收藏家460枚雨花石组华夏盛宴

收藏家460枚雨花石组华夏盛宴



糖藕 汤先锋 供图 糖藕 汤先锋 供图

  昨日起,一场别开生面的“象形雨花石展”在南京雨花台风景区的雨花石博物馆举行,888枚“象形雨花石”让人大开眼界.榴莲果、芒果、葡萄……博物馆里,一盘盘几乎乱真的“果肴”让人称奇,460枚雨花石组成的“华夏盛宴”更让人垂涎,“油炸鸡腿”、“烤卤猪头”、“白扒广肚”.这些雨花石来自南京雨花石协会副秘书长、摄影家汤先锋的收藏.整个展览为期两个月,5月28日结束.

  通讯员 张洪 扬子晚报记者 蔡震 杨娟

  看看他收藏的石头宝贝

  “罗汉果”上装把子能骗人

  几天前的一个下午,当记者走进汤先锋的家时,你会发现没地方插脚,满地都是一个个盘子、碟子.“盘子里都是石头,这是一桌水果宴席.”老汤拿起一个梨子让记者品尝,知道这位玩家,玩的是石头,所以记者不敢对梨子开口.于是他自己将梨子放进嘴里,咬了一口,是真的梨子.接着,老汤又从盘子里拿起几个罗汉果,有了前面的诚意,记者毫不犹豫地伸手去接,没想到这次上当了.老汤说,他忙了一夜,就是给这些石头打扮,按照水果的分类,装上不同的把子.

  扬子晚报记者看到,这桌水果宴有数十道,分3个玻璃转盘,最中间的是一组葡萄,一个椭圆白瓷盘里盛着紫红色的密植葡萄,周边6个瓷盘也全是葡萄.外围的两层盘子里,苹果、梨子、柿子、杏子、芒果、香蕉等水果一应俱全,3层共盛了满满56盘178枚雨花石,组成“硕果飘香”系列.

  “糖藕”里灌米饭还冒热气

  “水果宴”只是汤先锋展览的配角,共123盘的“华夏盛宴”还没“开席”.在客厅背后,有一间密室,很少让外人进.记者走进这间大约10个平方的房间,一张罗汉床上没有任何铺盖,只有几块玻璃台板,板上摆放着一个个用塑料膜密封的盘子.“这张床是件古董,原先买下是想给客人歇息的,但客厅全都被石头占据了,我自己也不曾坐过它,只好让位给石头了.”

  除了罗汉床摆满了“石盘”,床边也堆放着一个个很大的塑料箱子,里面全是密封好的瓷盘.老汤随便打开一个,一段“糖藕”展现在眼前.老汤说这是他的看家宝贝,不仅外形逼真,就连莲藕里面的空心都惟妙惟肖,空心中居然还灌满了米饭,仿佛冒着热气,从炉子上刚刚端下来.而一盘“紫茄子”更是叫绝,靠近把子的润色清晰可见,可谓是绝品.

  他就这样爱上了石头

  穿越沙漠时捡到一块“烤红薯”

  作为玩家,老汤玩石头10年都不到,之所以他玩出了名堂,靠的全是独特的创新意识.老汤告诉记者,七八年前,他背着摄影包,穿越蒙古的沙漠上.一次他坐在沙漠中,偶然一伸手从沙子中摸出一块石头,活像个烤红薯.从小生活在徐州农村,老汤说如果没有红薯,他活不到今天,红薯对他有着“救命之恩”.他没有丢弃这块戈壁石,把它塞进了摄影包中.

  从此,老汤开始与石头结下渊源,他开始四处寻找这样的石头.可是,他跑来跑去,南京玩石头的人,大部分都是玩放在水中看图纹的雨花石,哪有什么象形石?可老汤有股不服输的劲头,他经过在六合和仪征等地无数次的寻访,如愿以偿.说来也巧,居然他在清凉山又寻到一枚“山芋”,比那枚戈壁石还要逼真.

  专门收藏蛋形石,已有三千枚

  对六合当地采石的乡民来说,老汤相中的石头,他们根本就没往眼里去,要想寻找,必须得亲自上山.为此,老汤专门买了一辆车,一到周末就出发.有时一去就是一整天,连饭都顾不上吃.一次,老汤为了寻找石头,爬上了采石场的悬崖,不小心脚下一滑,他连人带相机滚下七八十米的山谷,同去的石友过了半天才找到他.

  从此,老汤玩石头玩命出了名,当地乡民见他就开玩笑说:“玩蛋来了.”因为,老汤有阵子专门挑雨花石中的蛋形石买,大伙也知道他的“怪癖”.开始,大家都很便宜地卖给他,后来,2009年老汤举办了展览,出版画册,大伙一下明白了,原来那些毛糙的,不起眼的雨花石也是宝贝.后来,跟着老汤的玩法的人越来越多,蛋石价格也越涨越高.他告诉记者,他收藏的各种七彩蛋石,已经达3000多枚.

  填补象形类雨花石的空白

  汤先锋说,他想通过这次展览告诉大家,雨花石不仅是“富人”玩的,老百姓也同样玩得起.而且,他还想证明,玩石头,绝不只是看价钱,最重要的是懂得欣赏,与石头建立友情.看着自己满屋子的石头,老汤说,“我绝不是为了拥有这些石头,我是想通过我的创意,将雨花石推向世界.”

  在老汤心中,传统的玩法,把雨花石放在水中,只看图文,不是不好,但显然过于单一,已经不能与世界接轨.“创作‘华夏盛宴’、‘水果宴’,是为了填补雨花石象形类的空白.希望我的探索,能为雨花石文化开创出一条新路子来.”老汤感慨地说.

浅谈翡翠和黄龙玉的特点与运用

玻璃种翡翠麒麟挂件欣赏

内容摘要:玉在中国人的心目中有着无比美好的形象,被认为是光荣和幸福的化身,是刚毅和仁慈的象征,已经深深地嵌镶在博大的中国文化之中。玉石历经沧桑岁月,仍旧美仑美奂、光彩不改。笔者在多年的从艺历程中,发现具有着“玉石之王”的翡翠和“后起之秀”的黄龙玉是雕刻艺术家青睐的品种,本文将从翡翠和黄龙玉独有的特点出发来谈它们在玉石雕刻中的运用。
  关键词:翡翠;黄龙玉;特点:运用
  “翡翠齐火,络以美玉。流悬黎之夜光,缀隋珠以为烛。金玉阶,彤庭辉辉。珊瑚琳碧,孺珉磷彬”,这是《西京赋》咏玉的名句。中国玉器经过七千年的持续发展,经过无数能工巧匠的精雕细琢,经过历代统治者和鉴赏家的使用赏玩,经过礼学家的诠释美化,成为了一种具有超自然力的物品,成为了人生不可缺少的精神寄托。玉已深深地融合在中国传统文化与礼俗之中,充当着特殊的角色,发挥着其他工艺美术材料不能替代的作用。
  中国有句至理名言,叫“他山之石,可以攻玉”,这道出了琢玉的真谛。事实上,巧夺天工的玉器,不是雕刻出来的,而是利用硬度高于玉的金刚砂、石英、柘榴石等“解玉砂”,辅以水来研磨玉石,琢制成所设计的成品。所以,用行话来说,制玉不叫雕玉,而称治玉,或是琢玉、碾玉、碾琢玉。琢玉的技巧是高超的,而治玉工具却是简陋的。语言为案例,来分析、论证剪纸艺术在城市景观空间中审美的独特性和可行性,以此为剪纸艺术的广阔发展和城市景观空间设计的发展思路提供了新的理念和方向。
  城市的概念属于非常复杂的社会范畴,它涉及到政治、经济、文化、历史等诸多方面的内容。由于不同的文化背景、经济状态以及社会意识形态,人们对于什么是“好的城市景观”会有各自不同的答案。20世纪80年代兰州黄河岸边的景观雕塑和公共空间设计,确立了自己的形象并影响深远,如《黄河母亲》《西天取经》《激流勇进》等雕塑作品,这些作品周围的空间景观经历了30年的岁月,在今天依然散发着独有的魅力。近年来如“兰州儿童公园”和“龙源”的景观空间又成为兰州城市的一大亮点。其独特性在于,在景观空间中不同程度地应用了民间剪纸的造型语言,并使之成为空间主题的一部分。在儿童公园景观空间中,像屏风一样的立体装饰墙上镶嵌着用红色钢板材料制作的剪纸,巧妙地将剪纸的平面性应用在立体的空间造型中,由于采用了剪纸镂空的特点,整体装饰性和通透性很强,就像中国画中追求“虚实”的原理一样。作为儿童的主要活动场所,使儿童在整体空间中既能体会游戏时的快乐,又能得到民间艺术潜移默化的熏陶。对于整个景观来讲,无论其独特性、创造性还是实用性和美观性在此逐一得到了体现。因此,城市形态和城市景观对生活在城市中的人们会产生巨大的影响确是不争的事实。我们应该多多探索民间传统文化艺术如何嫁接并融汇在当代生活的方方面面,如兰州“龙源”属于兰州滨河路上的标志性建筑,和儿童公园一样也采用了剪纸艺术语言,与立体的造型相结合成为整个龙源空间的点睛之笔,透过火烈烈的镂空剪纸屏风,流动的黄河从后穿越而过,与安静祥和、古拙质朴、粗犷奔放、单纯明快的“剪纸”相互映衬,有着强烈的空间艺术生命力。其完整的造型、独特的空间艺术视觉显示出剪纸艺术语素的独特魅力。
  剪纸艺术在过去曾被看作“粗俗”“雕虫小技”,被打入“大雅之堂外的另册”。但剪纸艺术以其所蕴含的巨大精神力量,象山花那样倔强地生长,一代代传承下来,今天她逐渐被人们所发现,带给人们惊诧和心灵的震憾。在今天一味西化的空间设计意识充斥、泛滥的状况下,借鉴民间剪纸元素,汲取民间剪纸艺术的营养是十分有益的,从而对提升城市景观空间的艺术品味、激发民众的地域自豪感、以及增强新形式、
  笔者从14岁开始在莆田民间习事传统木雕工艺,26岁创办莆田市艺峰工艺厂,原先以设计制作出口到日本寺庙古建装饰的平雕为主,但因市场竞争激烈,订单有限,企业发展维艰。于是,我开始谋划转向发展。经反复的市场调查,发现一些原先从事木雕的朋友在转向从事玉雕以后,发展势头良好。我便先与几位交情甚深的中国台湾客户商议,由我厂试产一些小件玉雕艺品,例如,我将莆田木雕的传统题材《三羊开泰》《麻姑献寿》等以玉的材质来雕刻,然后经他们的店铺及销售渠道试行推广;初试成功后,客户的兴致也来了,订单便逐渐变多变大。不仅小件传统玉雕人物,动物等各种题材的订单多了,而且中、大件玉雕佛像的订单也多了,甚至大型西方体裁的玉雕人物的订单也多了起来。玉料越进越多,越进越大;设备也越添越多,越添越新。短短几年时间,企业己经成功开发投产包括缅甸玉、黄龙玉、汉白玉和翡翠雕刻佛道神像、西方人物、动物艺品达五百多类,一千多个花色品种。产品远销欧美、日本、新加坡、马来西亚和台港地区,深受海内外客户好评。
  每次从云南到缅甸北部密支那地区购买玉料,都是难忘的学习过程。识货的,可以用较低的进价购得品质上乘的好料。不识货的,则可能枉费上倍的进价贴得品质下等的次料,甚至假货。因为企业产品大部分以佛像为主,所以我购买的材料大部分为缅甸白玉,其中也有备受青睐的翡翠。一些缅甸白玉会含带绿色,甚至含带黄石,如果以自为主,兼具绿黄紫等色,即属难得上品,就可以设计成配有道具、花叶巧色背景的佛像或花鸟巧色的摆件,这种作品的艺术附加值必然成倍增加。
  利用“巧色”是中国玉雕工艺的绝活,是根据一块玉料中巧出的颜色来设计作品,使玉料的不同颜色被应用得恰到好处而且非常巧妙,使天然的色斑在雕件中起到了点石成金的作用。说到巧色,我想以翡翠这种材质来分析。翡翠,是玉的一种,颜色呈翠绿色或红色,被称为“玉石之王”。郭沫若赋诗赞日:“玉王称翡翠,含耀尚流英。浓绿春心动,凝装古德馨。瑕瑜犹易辨,人鬼实难分。透视开门子,陶然赌石灵。”翡翠是世界五大珠宝之一,它具有着自己的特点:一是它的色泽绚烂、多彩多姿,有红翡,黄翡、绿翠、紫罗兰、白青等许多颜色,这么多种颜色能够齐聚在同一块玉料之中,这是其他玉石所没有胀二是其种类丰富,它是一种多晶体,其晶体的粗细、晶形的不同影响到它的透明度;三是可遇不可求,翡翠玉材的表现和颜色色彩、分布等各不相同,很难找到完全相同的翡翠;四是几乎所有的宝石均可用重量计价,雨翡翠具有的上述几大特性则要求综合衡量,没有一种标准的公式定价;五是翡翠的抗压性和抗热性很大,这些特有的物理性质提高了它的收藏保存价值。
  在我创作翡翠玉雕《硕果累累》中,采用的则是一块粉紫带绿的翡翠,晶莹剔透。在设计之时,以一块紫色为底,其上带有绿色的质地较细,透明度较好的粉紫翡翠上品为雕材,将绿色表层雕刻为茂密的葡萄叶,但见叶下藤蔓缠绕、硕果累累,葡萄架下荫凉处欢快的两只鸭子又令画面平添几分动感。作品构图风趣,取色巧妙,是一件质地、形色、工艺俱佳的作品。而我创作的另一件绿色含紫的翡翠玉雕《屏风十二花神》,以屏风的形式将十二花神展现其

冰种翡翠紫罗兰玉佛吊坠

间,斑驳翠绿的部分雕琢成随风摇曳的鲜花,这些鲜花在风的吹拂下此起彼伏地摇曳,犹如花神绰约的风姿、妩媚的笑容若隐若现地绽放在花丛之中。整个画面淡雅柔美,荡漾着一股唯美的气息。此作品荣获第五届中国(莆田)海峡工艺品博览会金奖。
  花开两朵,各表一枝:再说黄龙玉,又称龙黄石,是一种新兴美玉。在中华传统文化中,黄色最为尊贵并带有神秘的色彩。国人一直都在致力于黄色玉石的发现,以至于田黄石一出世就被封为石帝,为皇家和显贵专宠。黄龙玉在玉雕行业中,是一种堪称后起之秀的玉种,有和田玉之温润、田黄之色泽、翡翠之硬度、寿山石之柔韧,观之晶莹欲滴,抚之温润腻手。既可以是把玩的原石,也适合雕刻成各种摆件、饰品。黄龙玉,依出产地不同,可分为籽料、草皮料、山料等。目前市场价格最高的是籽料和草皮料。由于长年累月历经流水、山风的冲刷,赋予这两类原石滋润色彩和通透的灵气。黄龙玉的摩氏硬度6.5~7,与翡翠相当,比和田玉稍高。从时间来看,和田玉“出生”有7000多年。翡翠“出生”有300多年,黄龙玉只有7年。短短7年间,它从几毛钱一斤飞涨到了万元以上,创下了中国玉石史上的一个涨价奇迹。黄龙玉雕的研创要领有四点:即本身玉质、造型设计、作品意境、文化内涵等。
  一、本身玉质:赏析黄龙玉雕件酋先就要看它的自身品质:颜色、硬度、透明度、光泽等。
  二、造型设计:黄龙玉雕就造型设计而言主要应把握三点:玉雕物象的结构层次及空间表现力、色调的处理运用、形态及力点的美感。
  三、作品意境:玉雕的意境是玉石神韵的体现,是匠师精神的寄托与延伸。同一件黄龙玉雕件,不同的人可能有不同的精神感受,这就取决于个人的品味与境界的高低了。
  四、文化内涵:黄龙玉雕题材丰富多样,它承载和沿继了中华民族丰富的玉文化内涵。“玉必有工、工必有意、意必吉祥”。对玉石的品味和玩赏,自古以来就蕴含着文化,美学、宗教以及人们对未来的美好期盼和精神层面的享受。赏析黄龙玉雕件,不仅仅是评判它的审美价值、市场价值,也是在品读一个故事、分享一份情感,感受一个生命,更是一种自由自在的审美愉悦。
  例如我新近创作的黄龙玉雕《女娲补天》,据说远古水神共工和火神祝融交战时,共工被祝融打败后,气得用头去撞西方的不周山,将这座撑天的大柱撞塌了,天上出了一个巨大的窟窿,大地也被震裂。裂口中喷出的火焰燃烧着人间房屋和庄稼。洪水漫过两岸,人类生活的地方变成了…片汪洋大海。女娲为救苦救难,在黄河边挑选许多五彩石,加热或熔化后,再把天上的洞补起来。九天九夜过去后,天边才又重现五色云霞。作品以一块含红黄龙玉,刻画烧红的天际、挺身托举补天彩石的黄袍龙尾造型的女祸和腾空鼎力相助的神龙,画面色彩绚丽、人物动态感人。
  识玉难,研玉更难!然而为了谋生为了创新,必须知难而上。不论是坚硬的翡翠。稍软的缅甸玉、新兴的黄龙玉,均须坚持软硬兼攻勤创新,古今中外敢雕造。对材料喜新不厌旧,对作品创新不守旧,是我始终如一的研玉准则,藕有新面目的,在雕塑的语言上,形体的表现上,甚至连雕塑材料的选择上都需要突破。
  1.雕塑材料
  优秀的雕塑,除了内容的深邃,形式的生动感人,语言的独具匠心外,材料的选用上也有着非常重要的作用。成功力作,很大程度上受所用材料质地的直接影响。语言形式表现力发挥的充分与否,相应条件下取决于材料。各种材质因其不同的性能,会带给观者不一样的感觉,形成各种意想不到的效果。例如岩石坚硬质朴,青铜高雅抒情,陶土稚拙坦诚,木头温暖柔情……很长时间笔者一直在寻找什么材料能最好地表现自己的创作构想。
  天然大漆,又名国漆、生漆、土漆、木漆等,是我国的土特产之一,天然生漆就是人工从漆树割取的天然漆树液。中国人用漆的历史长达七千年,史书上关于漆最早的记载,出现在《韩非子》里,早在尧舜禹时代,漆器就已经成为部落联盟领袖使用的奢华之物了。从新石器时代第一件漆器的发现,到战国时期的繁荣,到唐代的空前发展,再到明清时期的百花齐放,漫长的岁月中,漆被赋予了浓郁的东方气质。生漆具有防腐蚀、耐强酸、耐强碱、防潮绝缘、耐高温等特征。经过提炼的大漆可以与不同的矿物质调和成各种颜色,加入铁变黑,加入朱砂则变赤,这些幻化而成的色彩,或明亮,或温婉,或雅静,满足了不同人的审美情趣,也让漆的包容性与可塑性得以彰显。可以产生晶莹剔透。

FDA’s 510(k) gets tougher, more predictable

FDA’s 510(k) gets tougher, more predictable



SAN JOSE, Calif. – The U.S. Food and Drug Administration has become tougher but more predictable in how it handles medical products seeking approval under its 510(k) process, said a consultant at the DesignMed conference, part of the Design West event here.

The observations come at a time when the FDA process has been undergoing internal reforms and intense scrutiny. The 510(k) is the fastest and most widely employed regulatory path for medical devices, used for about 4,000 products a year classified as moderate risk.

Since June, the FDA has been rejecting a greater number of 510(k) applications. However it is also becoming more consistent about its criteria and engaging applicants more directly, said the consultant.

Under the 510(k), applicants ask FDA examiners to approve a new device because it is “substantially equivalent” to an existing device, called a predicate. “Our experience is the FDA is getting pickier and picker on what they will accept as a predicate device,” said Chris Henza, a regulatory affairs specialist at Regulatory Compliance Associates, Inc. (Kenosha, Wis.), speaking in a DesignMed session.

In addition, the FDA has tightened up some parameters. In the past, applicants frequently pointed to as many as 30 predicate devices. But going forward, the FDA’s guidance suggests it will only consider one main and one secondary predicate device, she said.

However examiners also have been “consistently asking all the same questions,” said Henza who submitted a diverse set of five 510(k) applications in the last nine months.

“It’s definitely getting more predictable, they are actually doing what they say they are doing,” she said. “In the past there were more inconsistencies,” she added.

Late last year, the FDA issued new guidance on the 510(k) process as part of ongoing reforms it initiated in January 2011. The guidance included a flow chart to explain the process, something the agency seems to be following, Henza said.

The latest guidance statement was more detailed—nearly three times the length of past FDA guidelines for 510(k) applications—and the agency seems to be adhering closely to it. “They expect you to go through every point of your device and refer to all the guidance questions” in an application, she said.

In the past, examiners typically informed applicants of rejections by letter and fax. Since June, “they have actually called and asked questions” of applicants, she said.

“If you can explain what you are trying to do, they will put [the application] through,” she added.

The changes come at a time when the FDA has been under intense scrutiny. Congress mandated an external review of the 510(k) process, a job handled by a group of experts from the Institute of Medicine. The IoM’s report, issued last July, called for scrapping the 510(k) process completely, a conclusion the FDA and industry both were quick to reject.

GrammaTech transforms code analysis with visualization

GrammaTech transforms code analysis with visualization



San Jose, Ca. – At ESC DESIGN West here, source-code analysis specialist GrammaTech took the wraps off its next-generation software architecture visualization system.

According to Paul Anderson, VP of Engineering at GrammaTech, the new system incorporates a sophisticated new interface for viewing the relationships between software program elements. The system has been integrated with CodeSonar, GrammaTech’s static-analysis tool for detecting defects.

CodeSonar is a sophisticated static-analysis tool that performs a whole-program, interprocedural analysis on C/C++ code, and identifies complex programming bugs that can result in system crashes, memory corruption, concurrency errors and other serious problems.

According to Anderson the growing complexity of large software systems makes it more difficult for developers to test and analyze the interrelationships between elements of source code.

He said the CodeSonar visualization has been designed to optimize visual inspection and analysis of software, with real-time, fluid transitions for developers to visualize massive data sets to work at different levels of abstraction. The software makes extensive use of the graphics processing unit (GPU), is very high performance and can handle very large code bases (10M+ lines of code).

“Typically, text editors show just a few dozen lines of code at a time,” Anderson said. “Currently available visualization tools are effective at displaying small-scale parts of the program structure such as fragments of class hierarchies and subsets of the call graph, but it is infeasible to use those tools to show whole-program structures.Even for small projects, such tools become unusable because of complexity and performance.”

The new program-visualization capability was specifically designed to perform well on millions of lines of code. It presents data in a layered fashion, so users can choose to see only the information appropriate to the desired level of abstraction.

“Users can explore the program in a top-down fashion, starting with the outermost high-level modules and zooming in to reveal detail at a finer granularity; or can take a bottom-up approach if that is more appropriate to the task.”

CodeSonar visualization displays the program’s call graph organized according to the module structure of the program. Graph layouts can be changed in real time and present data in tree, map, circuit, cluster, flow, radial and other layouts. Data is featured in a layered way that provides a high-level view with drill-down capability; users can explore the program from the bottom up as well.

The new tool capability also includes other program understanding and navigation features, and supports annotations and sharing of diagrams between team members. Anderson said that with this capability, users can start at individual functions to gain insight from a bottom-up perspective, annotate nodes and edges with additional information and overlay the visualization with information on defects and source-code metrics such as complexity.

Other features include the ability of users to search the graph for functions of interest, view the graph in a variety of different layouts, and navigate to and from the source code of the program. In addition, the architecture is extensible, so users can generate graphs from other sources, feed them in an XML format to the tool and see them in the same user interface.

CodeSonar visualization can be by means of a standard web client such as Microsoft Internet Explorer, Firefox or Chrome browsers. An early release version is available to customers today. To learn more, go towww.grammatech.com.

藏家888枚雨花石呈现视觉盛宴

藏家888枚雨花石呈现视觉盛宴



糖藕 汤先锋 供图 糖藕 汤先锋 供图 茄子 茄子 罗汉果 罗汉果

  28日起,一场别开生面的“象形雨花石展”在南京雨花台风景区的雨花石博物馆举行,888枚“象形雨花石”让人大开眼界。榴莲果、芒果、葡萄……博物馆里,一盘盘几乎乱真的“果肴”让人称奇,460枚雨花石组成的“华夏盛宴”更让人垂涎,“油炸鸡腿”、“烤卤猪头”、“白扒广肚”。这些雨花石来自南京雨花石协会副秘书长、摄影家汤先锋的收藏。整个展览为期两个月,5月28日结束。

  看看他收藏的石头宝贝

  “罗汉果”上装把子能骗人

  几天前的一个下午,当记者走进汤先锋的家时,你会发现没地方插脚,满地都是一个个盘子、碟子。“盘子里都是石头,这是一桌水果宴席。”老汤拿起一个梨子让记者品尝,知道这位玩家,玩的是石头,所以记者不敢对梨子开口。于是他自己将梨子放进嘴里,咬了一口,是真的梨子。接着,老汤又从盘子里拿起几个罗汉果,有了前面的诚意,记者毫不犹豫地伸手去接,没想到这次上当了。老汤说,他忙了一夜,就是给这些石头打扮,按照水果的分类,装上不同的把子。

  扬子晚报记者看到,这桌水果宴有数十道,分3个玻璃转盘,最中间的是一组葡萄,一个椭圆白瓷盘里盛着紫红色的密植葡萄,周边6个瓷盘也全是葡萄。外围的两层盘子里,苹果、梨子、柿子、杏子、芒果、香蕉等水果一应俱全,3层共盛了满满56盘178枚雨花石,组成“硕果飘香”系列。

  “糖藕”里灌米饭还冒热气

  “水果宴”只是汤先锋展览的配角,共123盘的“华夏盛宴”还没“开席”。在客厅背后,有一间密室,很少让外人进。记者走进这间大约10个平方的房间,一张罗汉床上没有任何铺盖,只有几块玻璃台板,板上摆放着一个个用塑料膜密封的盘子。“这张床是件古董,原先买下是想给客人歇息的,但客厅全都被石头占据了,我自己也不曾坐过它,只好让位给石头了。”

  除了罗汉床摆满了“石盘”,床边也堆放着一个个很大的塑料箱子,里面全是密封好的瓷盘。老汤随便打开一个,一段“糖藕”展现在眼前。老汤说这是他的看家宝贝,不仅外形逼真,就连莲藕里面的空心都惟妙惟肖,空心中居然还灌满了米饭,仿佛冒着热气,从炉子上刚刚端下来。而一盘“紫茄子”更是叫绝,靠近把子的润色清晰可见,可谓是绝品。

  他就这样爱上了石头

  穿越沙漠时捡到一块“烤红薯”

  作为玩家,老汤玩石头10年都不到,之所以他玩出了名堂,靠的全是独特的创新意识。老汤告诉记者,七八年前,他背着摄影包,穿越蒙古的沙漠上。一次他坐在沙漠中,偶然一伸手从沙子中摸出一块石头,活像个烤红薯。从小生活在徐州农村,老汤说如果没有红薯,他活不到今天,红薯对他有着“救命之恩”。他没有丢弃这块戈壁石,把它塞进了摄影包中。

  从此,老汤开始与石头结下渊源,他开始四处寻找这样的石头。可是,他跑来跑去,南京玩石头的人,大部分都是玩放在水中看图纹的雨花石,哪有什么象形石?可老汤有股不服输的劲头,他经过在六合和仪征等地无数次的寻访,如愿以偿。说来也巧,居然他在清凉山又寻到一枚“山芋”,比那枚戈壁石还要逼真。

  专门收藏蛋形石,已有三千枚

  对六合当地采石的乡民来说,老汤相中的石头,他们根本就没往眼里去,要想寻找,必须得亲自上山。为此,老汤专门买了一辆车,一到周末就出发。有时一去就是一整天,连饭都顾不上吃。一次,老汤为了寻找石头,爬上了采石场的悬崖,不小心脚下一滑,他连人带相机滚下七八十米的山谷,同去的石友过了半天才找到他。

  从此,老汤玩石头玩命出了名,当地乡民见他就开玩笑说:“玩蛋来了。”因为,老汤有阵子专门挑雨花石中的蛋形石买,大伙也知道他的“怪癖”。开始,大家都很便宜地卖给他,后来,2009年老汤举办了展览,出版画册,大伙一下明白了,原来那些毛糙的,不起眼的雨花石也是宝贝。后来,跟着老汤的玩法的人越来越多,蛋石价格也越涨越高。他告诉记者,他收藏的各种七彩蛋石,已经达3000多枚。

  填补象形类雨花石的空白

  汤先锋说,他想通过这次展览告诉大家,雨花石不仅是“富人”玩的,老百姓也同样玩得起。而且,他还想证明,玩石头,绝不只是看价钱,最重要的是懂得欣赏,与石头建立友情。看着自己满屋子的石头,老汤说,“我绝不是为了拥有这些石头,我是想通过我的创意,将雨花石推向世界。”

  在老汤心中,传统的玩法,把雨花石放在水中,只看图文,不是不好,但显然过于单一,已经不能与世界接轨。“创作‘华夏盛宴’、‘水果宴’,是为了填补雨花石象形类的空白。希望我的探索,能为雨花石文化开创出一条新路子来。”老汤感慨地说。

碧玺成投资客新宠 一年里身价翻番

碧玺成投资客新宠 一年里身价翻番



  “疯狂的石头”遇冷,有价无市

  业内人士提醒,买碧玺忌盲目跟风,要综合考虑其质量和稀有程度

  按照惯例,每年开春时节,玉石市场都会迎来旺季.而近两个月,我市翡翠等玉石价格不断下跌.据临海紫阳路古玩集市上的玉石商贩反映,今年玉石几乎卖不动,即使是去年一度被热炒的黄龙玉也遭遇了跌价的命运.

  “疯狂的石头”价格暴跌

  上周六在临海紫阳路上的古玩集市上,玉石商戚亚林说,前几年,翡翠、和田玉等玉石价格很“疯狂”,几乎每一季以10%至15%的幅度增长,部分玉石一年时间能增值50%以上,这些玉石一度被称为“疯狂的石头”.然而,自年前开始,中低档玉石价格持续下滑,高档玉石虽然价格依然坚挺,但普遍呈现有价无市的现象.

  “中低档玉石以次充好的现象非常普遍,自然受到了人们的冷落,价格不断下跌.”戚亚林说.

  另一位玉石商周立新告诉记者,近两个月,低档玉石的价格已下跌25%~30%左右.“我现在每次去进货,低档玉石都不进了,中档玉石我会进多一点,放在店里也能卖出一些.”

  半年间碧玺价格涨一倍

  与玉石命运截然不同的是属中档宝石类的碧玺,随着时尚界刮起的彩色宝石风,碧玺成了投资客的“新宠”.

  “市场上一些不专业的商家介绍碧玺时,往往称它为水晶中的高档品,这是不对的.事实上,水晶是低档宝石,而碧玺属中档宝石.另外,水晶的硬度约6.7度至7.2度.碧玺又称电气石,硬度在7.6度至8.0度左右.”戚亚林说,碧玺常被用来镶嵌,流行于缅甸和泰国.近些年,碧玺采矿业迅猛发展,再加上时尚界的追捧,碧玺有望取代红、蓝宝石,成为消费市场的主流宝石.

  “碧玺计价模式,已由几年前的以‘件’计算改为‘克’计算.半年前,六七十元一克的碧玺,现在涨到了110元至120元了,短短半年时间,碧玺的价格几乎翻了一番.”周立新说.

  据了解,碧玺涨价快,除了颜色艳丽多彩、资源稀缺外,还与很多人信风水有关.碧玺谐音“辟邪”,而且“玺”字与古代的玉玺同字,所以广受欢迎.

  周立新介绍,碧玺共有14种颜色,其中两种颜色最昂贵:一是红色碧玺,红得越鲜艳品级越高;再者是绿色碧玺;与之相比,彩色碧玺的价格就大打折扣.“消费者购买时,不要盲目跟风,要买适合自己的.若是投资和收藏的话,还要考虑碧玺的稀有程度和质量.”周立新提醒到.

Exar cuts 40% of jobs

Exar cuts 40% of jobs



SAN JOSE, Calif.—Analog mixed-signal IC vendor Exar Corp. said Wednesday (March 28) it has eliminated about 40 percent of its global headcount in the past two months.

Exar (Fremont, Calif.) said it cut about 120 jobs Wednesday, or 30 percent of its worldwide headcount. The company eliminated 53 positions last month, Exar said.

Together, Exar expects the layoffs and other actions to save the company nearly $22 million per year, the company said.

"We believe that our remaining headcount of approximately 270 people is adequate and appropriate to support our needs in sales, marketing, product development, finance, human resources and other functional disciplines while we drive growth in our target markets," said Louis DiNardo, Exar's president and CEO, in a statement. "Our basic cost structure is sound; we have a major design center in China, a majority of test operations offshore and we are now a lean organization."

DiNardo said Exar was "very comfortable" with the company's ability to recruit and retain top talent to support product development in its areas of focus.

Exar outlined its areas of product focus, including power management and control, data compression and security, connectivity and interface, and high-performance analog mixed-signal.

DiNardo said Exar is on track to hit its sales targets in the current quarter and that the company's bookings have improved compared to the previous quarter. Exar also sees positive signs in sales through its channel partners, DiNardo said.

Indian design firms eye chip IP model

Indian design firms eye chip IP model




BANGALORE, India – When Ittiam Systems, a media processing company here, said last week that more than 35 percent of its $20 million in annual revenues came from licensing its intellectual property, one observer called it a “landmark” for the company, adding that it was “an encouraging sign for the new generation technology companies in India.”

Ittiam is one of the few Indian companies to successfully deploy an IP licensing model, with sales of about $7 million. That’s small by global standards, but significant here. Another Indian company, Cosmic Circuits, a provider of analog and mixed-signal IP cores, has since announced it “aims to be a major player in semiconductor IP.”

“Cosmic started with power management IP in 2005 and has over 300 IP [offerings] and also solutions at 28 nm,” said CEO Ganapathy Subramaniam. “We estimate that over 50 million ICs have been shipped with Cosmic IP. We wanted to expand our portfolio and decided to focus on the connectivity IPs. We are now developing solutions for PCI Express, USB3.0, USB2.0 and HDMI apart from MIPI DPHY and MPHY in 28 nm and 20 nm.”

The early success of Ittiam and Cosmic illustrates the shift in India from design projects for overseas chip companies to generating and retaining chip IP.

According to Ganesh Ramamoorthy, research director at Gartner: “As is the tradition in the Indian technology sphere, most Indian companies try and avoid the risks associated with a product business – low margins, high development and marketing costs, rapid technological changes, ongoing R&D investments and, last but not the least, product acceptance by consumers in a market filled with” large, established players. This aversion to risk has prompted most Indian electronics companies to pursue the safer services business.

Cosmic is targeting what Ramamoorthy called the “wired interface IP market.” During 2010, that market was worth $305 million and is estimated to grow at a compound annual rate of nearly 11 percent through 2015 to $508 million.

India has trailed the rest to the industry in IP generation due to factors like high investment costs needed to acquire the necessary tools for IP generation, the lack of qualified analog/mixed signal engineers and the absence of a local ecosystem. Even if Indian companies could generate IP, few product companies would license this IP, said Deepa Doraiswamy, an analyst with Frost & Sullivan.

“Semiconductor IP creation is a long-drawn process where the IP has to be proven before it is marketed,” added Venkat Mattela, chairman and CEO of Redpine Signals. That means several silicon tape outs, reference designs and other time-consuming steps. “This requires spending a lot of time with experts, [it] means burning cash,” Mattela added. Indian engineers “are more inclined towards doing software where the results could be obtained much sooner, hence semiconductor IP development is lagging.

Still, some industry trends offer hope for more IP development here. India accounted for less than 1 percent of global chip IP in 2005, but currently produces about 5.5 percent, Doraiswamy estimated. That makes India the second largest IP producer along with the U.K.

Doraiswamy added that growing expertise in mixed-signal IP for wireless applications could become a key niche for Indian developers.

Time-to-market pressures and shortened product life cycles may also work to the advantage of Indian IP developers. “As a result, we believe that the standards-based interface IP market offers significant growth opportunity for third-party semiconductor design IP vendors like Cosmic Circuits,” said Ramamoorthy of Gartner.

Either way, companies like Ittiam and Cosmic Circuits seem determined to make some noise in the chip IP market as others here continue to focus on traditional chip design services.

'Thermal cloak' to dissipate heat in electronics

'Thermal cloak' to dissipate heat in electronics



MANHASSET, NY -- A team of French researchers have found a way of isolating or cloaking objects from sources of heat by diffusing the heat around the objects.

The “thermal cloaking” method taps into some of the same principles as optical cloaking and may lead to novel ways to control heat in electronics.

Recent advances in invisibility cloaks are based on the physics of transformation optics, which involves metamaterials and bending light so that it propagates around a space rather than through it. The French researchers investigated whether a similar approach might be possible for thermal diffusion.

“Our key goal with this research was to control the way heat diffuses in a manner similar to those that have already been achieved for waves, such as light waves or sound waves, by using the tools of transformation optics,” said researcher Guenneau Sebastien.

Guenneau is affiliated with both the University of Aix-Marseille and France’s Centre National de la Recherche Scientifique (CRNS).

The researchers applied the mathematics of transformation optics to equations for thermal diffusion to create their thermal invisibility cloak. They altered the geometry of isotherms to make them go around rather than through a circular region so that any object placed in this region can be shielded from the flow of heat.

“We can design a cloak so that heat diffuses around an invisibility region, which is then protected from heat. Or we can force heat to concentrate in a small volume, which will then heat up very rapidly,” Guenneau said.

Guenneau and colleagues said they are developing prototypes of their thermal cloaks for microelectronics, which they expect to have ready within the next few months.

The original research paper was first reported in the journal Optics Express.

Panel ponders many-core ICs tripping 'the singularity'

Panel ponders many-core ICs tripping 'the singularity'




SAN JOSE, Calif. – Will the rapidly increasing processing power being enabled by many-core processors cause the advent of machines with super-human intelligence, an event sometimes referred to as the singularity?

That was the question put to a panel of some of the best minds in multicore processor theory and design assembled on Tuesday (March 27) by analyst Jon Peddie at the Multicore DevCon, part of DESIGN West being held here this week. A small but enthusiastic audience was there to listen.

Peddie set up the debate by referencing Vernor Vinge, a science fiction writer, who had predicted that computing power would be equivalent to human processing power by about 2023. One particular aspect of the concept of the singularity is that once machines either in single units or collectively exceed human intelligence there may be an explosion of machine learning advancement that it would not be possible for humans to fathom, by definition, making the singularity a kind of event horizon.

Another extrapolation of computing progress had 2045 as the year in which it might be possible to buy a machine with the processing power of human brain for $2,000 in 2045.

Pradeep Dubey of Intel parallel computing labs illustrated the progress by saying that a petaflops supercomputer can already simulate a cat's brain. A human brain has 20 to 30 times more neurons and 1,000 times more synapses, he said, so the complete simulation of human brain is only a matter of a 5 or 6 years away. "Exaflops could simulate a human brain," he said.

Dubey said there are currently three approaches: simulate the process with a neuron- and synapse-level model; ignore brain architecture and treat the problem as data and statistical problem; or to build hardware that mimics neurons and synapses.

However, the simulation of the brain is not the same as thinking or generating the emotional intelligence we see in human beings, said Ian Oliver director of Codescape development tools at processor licensor Imagination Technologies Group plc. "We probably have the wrong memory model. The human brain is non-deterministic. It operates on the edge of chaos," he said.

Oliver pointed out that the use of genetic algorithms to derive FPGA designs through evolution produced much more brain-like architectures but were not readily usable in the real world and as such computer and human intelligence appeared to be distinct.

Mike Rayfield, vice president of the mobile business unit at Nvidia argued that the number of processor cores is a red herring. But Intel's Dubey countered that more cores is better saying that massive data engines can capture correlations if not causality. He pointed out that machines can already do some things far better than humans, which is the reason they exist. "We can build planes but we can't build birds," he said.

SAN JOSE, Calif.—UBM Electronics, a division of UBM plc and the publisher of EE Times, EDN and other publications, honored companies, teams and individuals for achievements over the past year by presenting the 2012 UBM Electronics ACE Awards in a ceremony here Tuesday (March 27).

The new award program, which combines the EE Times ACE (Annual Creativity in Electronics) Awards and EDN's Innovation Awards, was conducted in conjunction with DESIGN West, a new conference and expo built around the rich foundation of training, education and products available at ESC, combined with popular summits and new event launches in one venue for the first time.

The UBM Electronics ACE Awards recognize and honors the people and companies behind the technologies and new products that are changing the world of electronics globally.

A panel of EE Times editors narrowed down the entries to five finalists in each category, based on the criteria set forth in an online submission form. Winners were determined from among the finalists by a panel of independent judges. Judging took place from Nov. 1, 2011, to Jan. 6, 2012.

"It was a challenge for our judges to select one winner in each category from all of the creative and innovative technologies represented by the finalists," said Junko Yoshida, editor in chief of EE Times. "The winners have proven that they are pioneers in developing and implementing breakthroughs in electronics. We hope this awards program gives companies worldwide the impetus to stretch their imaginations and their resources for even more progress in the coming year."

Stay tuned for a slideshow that depicts the 2012 ACE Award winners at Tuesday's ceremony, which will be posted later today.

Imperas preps fast models of ARM Cortex-A15 processor

Imperas preps fast models of ARM Cortex-A15 processor




SAN JOSE, Calif. – Imperas Software Ltd. (Thame, England), a pioneer of high-level modeling and virtual prototyping, has models of the ARM Cortex-A15 processor in beta and expects them to be available in the first half of 2012. The range of available models, together with Imperas tool and operating system support, is helping platform and software developers debug systems in parallel with SoC design, speeding up and improving system development, the company said.

The company now has about 75 fast processor models covering MIPS, Renesas, ARM and Synopsys's ARC architectures, according to Larry Lapides, vice president of sales at Imperas. The support of the Renesas V850 architecture for microcontrollers has helped Imperas win work in the automotive domain, Lapides said.

OVP processor models are instruction accurate and employ a use a method of just-in-time code transformation to accelerate simulation speeds. The processor models can also be integrated into SystemC/TLM2 based virtual platforms using the native TLM2 interface available with all OVP models. The OVP simulator can also be encapsulated within the Eclipse IDE, enabling easy use for software developers.

In addition to models Imperas offers the Open Virtual Platform (OVP) simulator OVPsim that executes the models. The use of the open-source models, verified to accurately demonstrate the processor behavior, allows users to put together a simulation model of a platform, compile it to an executable, and connect it to a debugger to provide an embedded software development environment before an SoC has been manufactured. This allows software to be run and bugs to be caught, even extending to errors in compilers, the company said.

Simon Davidmann, founder and CEO of Imperas, said that the offering of virtual platforms for processor-FPGA platforms by Altera and Xilinx had helped business as it had validated the high-level modeling concept. "In fact it is our technology in the Xilinx Zynq virtual platform."

Imperas is now also offering the M*SDK set of Eclipse-based debug tools for use with OVPsim and fast processor models. And has validated support for a variety of operating systems running on top of software simulations. The speed of OVPsim makes the running of portions of applications feasible.

OS support now includes: Linux, Nucleus, uC/OS and FreeRTOS amongst others, said Lapides. "And, of course, Android sits on top of Linux, which opens up a broad applications space," said Davidmann.

Akustica develops two-chip analog MEMS microphone

Akustica develops two-chip analog MEMS microphone



PORTLAND, Ore. -- Akustica is entering the mobile device market with its first analog microphone, a low-cost two-chip solution that it hopes will widen its market share.

The Bosch subsidiary pioneered the single-chip digital MEMS microphone back in 2006, when its biggest competition was analog mics designed for hearing aids.

Akustica is the world leader in digital MEMS microphones with its elegant one-chip CMOS solution that has captured the lion's share of the microphone market for digital devices like laptop computers. However, the larger mobile phone market has been slow to adopt digital microphones, opting instead to stick with the ultra-inexpensive analog microphones produced by high-volume manufacturers like Knowles Acoustics (Itaska, Ill.). Now Akustica, backed by Bosch's high-volume manufacturing capabilities, hopes to carve out a bigger share of the billion-unit mobile phone market.
