This study investigates the morphological variation and taxonomic affinities of 28 fossil gibbon molars from eight newly discovered Pleistocene cave sites in the area of Chongzuo, Guangxi Zhuang Autonomous Region, China. A recent descriptive analysis demonstrated that these fossil teeth form a uniform group that can be assigned to a single species of Nomascus. In this contribution, a two-dimensional morphometric approach is employed to examine the Chongzuo specimens in comparison with a large sample of extant hylobatids, as well as with previously reported hylobatid dental remains from the Pleistocene of China. Buccolingual and mesiodistal measurements and crown outline areas reveal that the Chongzuo molars correspond most closely with Nomascus and, to a lesser extent, Hoolock. Crown shape was investigated using elliptical Fourier analysis. Our results show that the Chongzuo specimens fall in most cases either within the range of variation of extant Nomascus to the exclusion of all other hylobatid genera, or their distance from the cluster represented by the Nomascus sample is relatively small. Similarly, the Mahalanobis distances for crown shape show a trend towards smaller morphological distances between the Chongzuo specimens and Nomascus, followed by Hoolock and Hylobates. The Chongzuo molars are also morphometrically distinct from Bunopithecus sericus, but fall within the range of overlap of other Pleistocene hylobatid dental remains from southern China. The balance of evidence indicates that the Chongzuo teeth can be attributed to cf. Nomascus. The fossil teeth are sufficiently distinct from those of extant Nomascus that they may represent an extinct species.

中国新疆ウィグル自治区のハミウリは <i>cassaba</i>, <i>chandalak</i>, <i>ameri</i> および <i>zard</i> の 4 変種に分類されているが,その遺伝的多様性についてはほとんど研究されていない.そこで,ハミウリおよび近隣地域の在来品種を含むメロン 120 系統を供試して,遺伝的多様性ならびに類縁関係を解析した.ハミウリ 24 品種の種子長はいずれも 9 mm 以上であり,欧米のフユメロン変種と同じく大粒系に分類され,中国東部のマクワ・シロウリ(小粒系)とは明瞭に異なった.一方,イラン,アフガニスタン,パキスタンおよび中央アジア諸国では,大粒系および小粒系の両者が混在していた.PS-ID 領域(<i>Rpl16-Rpl14</i>)の SNP(一塩基多型)および ccSSR7 マーカーにより葉緑体ゲノムの塩基配列多型を解析した結果,供試したメロン品種が 3 種類の細胞質型(母系)に分けられること,そしてハミウリの細胞質型(T/338bp 型)が欧米のフユメロン品種(T/333bp 型)と異なることが明らかになった.一方,RAPD および SSR マーカーを用いた核ゲノムの多様性解析では,ハミウリの多様性指数(D = 0.243)が他地域の在来メロンより低いことが判明した.系統間での遺伝的距離に基づくクラスター分析の結果,ハミウリのうち果実の貯蔵性に優れる <i>ameri</i> 変種および <i>zard</i> 変種のほとんどが第 2 クラスターに分類されたことから,両変種は遺伝的に分化していないと考えられた.一方,早熟で果実の貯蔵性が悪い <i>chandalak</i> 変種は第 4,第 6 クラスターに分類され,上記 2 変種とは遺伝的に分化していることが判明した.第 2 クラスターには他地域のメロン 12 系統も含まれたが,このうちトルクメニスタンおよびアフガニスタンのメロン 3 系統がハミウリと同じく大粒系(種子)で T/338bp 型(細胞質)であったことから,ハミウリが西方から導入されたと考えられた.これに対して,中国東部のマクワ・シロウリは小粒系,A/338bp 型であり,また核ゲノムの解析でも第 1~第 9 クラスターから遠く離れた第 10 クラスターに分類されたことから,ハミウリとは別起源であることが示された.<br>

Tissue engineering offers considerable promise in the repair or replacement of diseased and/or damaged tissues. The cellular component of this regenerative approach will play a key role in bringing these tissue engineered constructs from the laboratory bench to the clinical bedside. However, the ideal source of cells still remains unclear and may differ depending upon the application. Current research for many applications is focused on the use of adult stem cells. The properties of adult stem cells that make them well-suited for regenerative medicine are (1) ease of harvest for autologous transplantation, (2) high proliferation rates for ex vivo expansion and (3) multilineage differentiation capacity. This review will highligh the use of adipose tissue as a reservoir of adult stem cells and draw conclusions based upon comparisons with bone marrow stromal cells.

This paper proposes approaches to perform HW/SW (Hardware/Software) partition and parallelization of computing-intensive tasks of the H.264 HiP (High Profile) decoding algorithm on an embedded coarse-grained reconfigurable multimedia system, called REMUS (REconfigurable MUltimedia System). Several techniques, such as MB (Macro-Block) based parallelization, unfixed sub-block operation etc., are utilized to speed up the decoding process, satisfying the requirements of real-time and high quality H.264 applications. Tests show that the execution performance of MC (Motion Compensation), deblocking, and IDCT-IQ (Inverse Discrete Cosine Transform-Inverse Quantization) on REMUS is improved by 60%, 73%, 88.5% in the typical case and 60%, 69%, 88.5% in the worst case, respectively compared with that on XPP PACT (a commercial reconfigurable processor). Compared with ASIC solutions, the performance of MC is improved by 70%, 74% in the typical and in the worst case, respectively, while those of Deblocking remain the same. As for IDCT_IQ, the performance is improved by 17% no matter in the typical or worst case. Relying on the proposed techniques, 1080p@30 fps of H.264 HiP@ Level 4 decoding could be achieved on REMUS when utilizing a 200 MHz working frequency.

This paper introduces a cycle-accurate Simulator for a dynamically REconfigurable MUlti-media System, called SimREMUS. SimREMUS can either be used at transaction-level, which allows the modeling and simulation of higher-level hardware and embedded software, or at register transfer level, if the dynamic system behavior is desired to be observed at signal level. Trade-offs among a set of criteria that are frequently used to characterize the design of a reconfigurable computing system, such as granularity, programmability, configurability as well as architecture of processing elements and route modules etc., can be quickly evaluated. Moreover, a complete tool chain for SimREMUS, including compiler and debugger, is developed. SimREMUS could simulate 270 k cycles per second for million gates SoC (System-on-a-Chip) and produced one H.264 1080p frame in 15 minutes, which might cost days on VCS (platform: CPU: E5200@ 2.5 Ghz, RAM: 2.0 GB). Simulation showed that 1080p@30 fps of H.264 High Profile@ Level 4 can be achieved when exploiting a 200 MHz working frequency on the VLSI architecture of REMUS.
