Wood frog Lithobates sylvaticus tadpoles develop in temporary wetlands where high population densities can force tadpoles into aggregations that intensify competition and can lead to cannibalism. However, chemical alarm cues released from injured conspecifics could also dissuade cannibalism. The purpose of this study was to test mechanisms that may influence can- nibalistic behaviour. We tested whether the tendency of tadpoles to consume conspecifics would increase with the presence of competition and/or cues of profitable diets. Tadpoles placed in 1L experimental containers were tested for feeding initiation times of multiple diets, including conspecific tissues and conspecific tissues combined with chemical cues from the alternative diets （brine shrimp and comrneal）. Tadpoles were tested in the presence and absence of a competitor, and at multiple times over the course of the study. Tadpoles exhibited an altered response to diets over time; however the presence of a competitor reduced re- sponse times to all diets including conspecific tissues. similarly, the presence of specific diets also reduced the response time of tadpoles to conspecific tissues. These results suggest competition among feeding tadpoles could result in aggressive behaviour leading to indiscriminate predation and cannibalism [Current Zoology 60 （5）： 571-580, 2014 ].

Staghorn calculi comprise a unique subset of complex kidney stone disease. Percutaneousnephrolithotomy (PCNL) is the gold standard treatment for staghorn stones. Despitecontinuous refinements to the technique and instrumentation of PCNL, these stones remaina troublesome challenge for endourologists and are associated with a higher rate of perioperativecomplications than that for non-staghorn stones. Common and notable intraoperativecomplications include bleeding, renal collecting system injury, injury of visceral organs, pulmonarycomplications, thromboembolic complications, extrarenal stone migration, andmisplacement of the nephrostomy tube. Postoperative complications include infection and urosepsis,bleeding, persistent nephrocutaneous urine leakage, infundibular stenosis, and *** this review, we report recommendations regarding troubleshooting measures that can beused to identify and characterize these complications. Additionally, we include informationregarding management strategies for complications associated with PCNL for staghorn calculi.

This paper proposes a new architecture-level thermal modeling method to address the emerging thermal related analysis and optimization problem for high-performance multi-core microprocessor *** new approach,called Thermsid,builds the thermal behavioral models from the measured or simulated thermal and power information at the architecture *** builds the thermal models by first generating a Hankel matrix of Markov parameters,from which state matrices are obtained through minimum square *** to existing behavioral thermal modeling algorithms,the proposed method is much more general as it does not require step temperature responses,leading to greater flexibility during the modeling *** results on a real quad-core microprocessor show that Thermsid provides accurate thermal behavioral models comparable existing approaches.

一、前言在材料化学中,一个很重要的问题是确定材料中加入多少量的别种离子或离子团以取代原来的离子,而不使原来的结构产生变化。这是寻找新材料的一个重要途径。目前,迅速发展的核能源中,一个迫切需要解决的重大研究课题是核废料处理。而将核废料用固体反应引入一种稳定的矿物,如硅灰石,可能是解决这一课题的一个十分有希望的途径。以前的研究指出,Sr2+取代ca2+可以使链状硅灰石（caSiO3）(照片1a)成为环状的假硅灰石结构（照片1b）;锗取代硅氧四面体中的硅可以形成环-链结构的共生长。从几何因素上考虑,铝氧四面体[AlO4]和硅氧四面体[SiO4]大小相近。因此用[AlO4]

硅灰石（caSiO3）是链状硅酸盐。本工作发现,用锗局部取代硅所形成的硅锗酸钙,只要取代量X≤0.2,其结构与硅灰石完全相同。但形成的多型体无序程度较高。样品由氧化钙、二氧化锗和二氧化硅在1500℃反应制得。在制备过程中,配料按照关系MSi+MGe=Mca进行。式中MSi,MGe和Mca分别代表SiO2,GeO和caO的克分子数。由此取代量为:X=MGe/MGe+MSi。对制得的ca(Si1-xGex)O3晶体进行X—射线衍射和电子衍射,均证明其结构与硅灰石相同。样品用JEOL200CX高分辨电子显微镜进行了观察并获得晶格象照片。晶格象指出ca(Si0.8Ge0.2O3具有硅灰石结构。晶格象还显示单斜和三斜两种多型体交替分布的情形。其无序分布程度较高。
