This paper reports our learning support system for a human learner to visualize his/her mental learning processes with invisible mazes. The objective of this research is to bring the learning ability of the learning agent close to that of a human. To fill in the missing piece of reinforcement learning whose learning process is mainly behavior change, we add two mental learning processes, awareness as pre-learning process and reflection as post-learning process. To observe mental learning processes of a human, we propose a new method for visualizing mental learning processes by the reflection subtask with invisible mazes. As the experimental results, there is a strong negative correlation between the number of discovered solutions of the continuous learning task and the reflection cost. It suggests that subjects whose number of discovered solutions is upper do a very good job of the reflection subtask.

A new N-acetylsulfanilylation series of uridine have been synthesized in good yield using direct acylation method and afforded the 5’-O-N-acetylsulfanilyluridine. In order to obtain newer products, the 5’-O-N-acetylsulfanilyluridine derivative was further transformed to a series of 2’,3’-di-O-acyl derivatives containing a wide variety of functionalities in a single molecular framework. The chemical structures of the newly synthesized compounds were confirmed on the basis of their FTIR, 1H-NMR spectroscopy, physicochemical properties and elemental analysis. All the synthesized uridine derivatives were tested for their in vitro antibacterial activity against six human pathogenic bacterial strains and for comparison standard antibiotic Ampicillin was also determined. The study revealed that the selectively acylated deriva-tives 5’-O-N-acetylsulfanilyl-2’,3’-di-O-lauroyluridine and 5’-O-N-acetylsulfanilyl-2’,3’-di-O-pivaloyluridine showed highest inhibition against Staphylococcus aureus and Bacillus cereus, respectively. We also observed that the introduction of hexanoyl, decanoyl, lauroyl, myristoyl and pivaloyl groups, the antibacterial functionality of the compound uridine increases. Another noteworthy observation was that the uridine derivatives were found comparatively more effective against Gram-positive microorganisms than those of Gram-negative microorganisms. In addition, the test chemicals were also tested for cyto-toxicity by brine shrimp lethality bioassay and compounds showed different rate mortality with different concentrations.

AIM: To investigate child and adolescent psychiatrists'(CAPs) attention deficit hyperactivity disorder(ADHD) and oppositional defiant disorder(ODD) diagnoses and treatments in real-world clinical practice. METHODS: The medical records of 69 ADHD children(mean age = 9.5 years), newly referred to the ADHD clinic, were reviewed for their scores of parent- and teacher-reported Vanderbilt ADHD Diagnostic Rating Scales(VADRSs), CAPs' diagnoses of ADHD and ODD, and CAPs' treatment recommendations. Among 63 ADHD subjects who completed both parent and teacher VADRSs, we examined the agreement of the parent and teacher VADRSs. We also examined the concurrent validity of CAPs' ODD diagnoses against the results from the VADRSs. In addition, we compared CAPs' treatment recommendations against established ADHD and ODD ***: Among 63 ADHD subjects, the majority of the subjects(92%) met full ADHD diagnostic criteria at least in one setting(parent or teacher) on the VADRSs. Nearly half of the patients met full ADHD diagnostic criteria in two settings(parent and teacher). Relatively low agreement between the parent and teacher VADRSs were found(95%CI:-0.33 to 0.14). For 29 children who scored positive for ODD on the rating scales, CAPs confirmed the ODD diagnosis in only 12 of these casepositives, which is considered as a fair agreement between CAPs and VADRSs(95%CI: 0.10-0.53). For 27 children with no ODD diagnosis made by either CAP or VADRS, more than half of them were recommended for medication only. In contrast, where CAPs made the diagnosis of ODD, or where the parent or teacher VADRS was positive for ODD, almost all of the patients received recommendations for medication and behavior ***: CAPs' ADHD diagnoses have strong concurrent validity against valid rating scales, but ADHD's most common comorbid condition- ODD- may be underrecognized.

粒子网格混合方法在求解两相流动问题时耗时巨大,本文对此提出了一种基于MPI(Message Passing Interface)环境的并行算法,其中包括并行求解网格与粒子两部分。通过与原有串行程序对比验证了并行化的正确性,通过实例计算证明该方法在一定范围内可以缩短计算时间,对于改进粒子网格混合方法与扩大其应用范围具有一定的参考价值。

核,一剂治病良药

大学生 2012年第10期 69-69页

作者： yuki 南开大学

所谓核医学,是指在检查或治疗中应用核技术的医学即利用放射性核素诊断和治疗疾病,现在主要应用于心脏显像、骨显像、甲亢、肾病及肿瘤的治疗,因此在我们眼里,＂核＂就是一剂治病良药。
