Weng, Wei-Lien,Liu, Vi-Chung,Lin, Chin-Wen Asian Australasian Association of Animal Productio 2001 Animal Bioscience Vol.14 No.10

Kou Woan Lao is an oriental-style dairy product, which is coagulated by milk-clotting enzyme from the culture filtrate of lao-chao. The product appears smooth, sweet, slightly wine flavour, and the flavour differs from yogurt. The aim of this study was to search for the optimum model to shorten the period of manufacture, and to improve the quality of Kou Woan Lao. A response surface design was used for studying the effects of addition of carrageenan, locust bean gum, and culture filtrate from lao-chao on the curd firmness, viscosity, and syneresis. Results indicated that the best rheological property, preservative quality and acceptability of Kou Woan Lao could be obtained by the combination of 0.22% carrageenan, 0.21 % locust bean gum and 12% culture filtrate from lao-chao. The curd firmness, viscosity and syneresis of resultant product were 29.3 g, 21,347.7 cps, and 8.92%, respectively and the microstructure of the curd revealed a relatively complete three-dimensional spider web-like structure.

A Multi-Domain Web Text Feature Extraction Model for e-Science Environment

Weng Yu 보안공학연구지원센터 2015 International Journal of Signal Processing, Image Vol.8 No.11

The traditional information extraction methods based on specific domain usually depend on the domain dictionaries to discover the text feature. It is inconvenient for reproducing and difficult to transplant in multi-domain environment. The application scope is limited seriously. Oriented to the deficiencies above, a multi-domain web text feature extraction model for e-Science is proposed (named e-FTM). This model adopts the Chinese split words technology without dictionary into the process of multi-domain text feature discovery and avoids the dependency of domain dictionaries effectively. With the help of classification of common and individual features, the model tracks the generation and the development trend of domain events dynamically, and forms a couple of local data centers eventually. Through cooperative scheduling the domain knowledge between different local data centers, the knowledge utilization efficiency of the domain information in the global scope is improved sharply. To validate the performance, the experiments on the multi-domain text feature extraction, topic features dynamical tracking and the domain knowledge cooperative scheduling demonstrate that the model has higher application validity and practicality in e-Science environment.

Effect of Nursing Frequency and Creep Feed Provision on the Milk and Feed Intake and Performance of Zero Day Weaned Piglets Reared on a Dummy Sow

Weng, R.C.,Edwards, S.A.,Hsia, L.C. Asian Australasian Association of Animal Productio 2009 Animal Bioscience Vol.22 No.11

One hundred and forty-four piglets with an average birth weight of 1,672${\pm}$13.4 g were used to evaluate different feeding strategies for piglets reared from birth on a dummy sow. A 3${\times}$2 factorial experiment compared three nursing frequencies (1, 3 or 6 h intervals) and two feeding regimes (milk only, or milk combined with access to creep feed and water). The piglets which were nursed at one hour intervals had the lightest body weights at all days, and the poorest combined milk and creep feed dry matter conversion efficiency to piglet body weight gain in the second week. Piglets which were nursed at 3 h intervals had the heaviest body weight at day 15 and 22, but those nursed at 6 h intervals achieved similar body weight by days 29 (milk withdrawal) and 36. Piglets offered creep feed were observed to wean themselves before cessation of milk availability, and the timing of this self-weaning depended on the nursing frequency. The piglets nursed at one hour intervals weaned themselves between day 22 and day 29, those nursed at 3 h intervals weaned themselves between day 15 and day 22, whilst those nursed at 6 h intervals weaned themselves between day 8 and day 15. The piglets which were nursed at 6 h intervals had the highest total dry matter intake in weeks 3 and 4 when fed with milk, creep feed and water but not when fed milk only. They consequently had the poorest dry matter conversion efficiency in the fourth week and overall when fed with milk, creep feed and water, but not when fed milk only. It is concluded that the optimal management routine under these conditions is a 3 h nursing cycle with provision of supplementary creep feed and water.

THE CHARACTERISTICS OF ZINC DIFFUSED NORMALLY ON GaAs AND InP JUNCTION FETs

Weng, Tung H. 대한전자공학회 1989 ICVC : International Conference on VLSI and CAD Vol.1 No.1

In this paper, a new technique using semi-sealed quartz bottle for zinc diffusion in GaAs and InP was employed. The basic requirement for zinc diffusion in these materials is to provide an overpressure ambient 50 that decomposition at the diffusion temperature can be avoided. This was done for the case of InP by placing InP wafer with diffusion charge which contained pure zinc and a small amount of InP powder in a semi-sealed bottle. This small amount of InP powder seemed to have provided the needed overpressure ambient to avoid decomposition. TA e surface showed no degradation after diffusion and maintained its original smooth surface. However, the surface was decomposed if no InP powder was added in the diffusion charge. For the case of GaAs, no GaAs powder was needed in the diffusion charge. Only pure zinc was required for producing heavily doped P-layer. The vapor produced by GaAs in the semi-sealed bottle during diffusion seemed to be sufficient to avoid decomposition. This is in sharp contrast to the behavior of zinc diffusion in InP using the same technique The detailed characteristics of the diffused layer of InP are presented. Similar characteristics for GaAs were also obtained. Junction field effect transistors were fabricated using the P layer formed by semi-sealed diffusion for both InP and GaAs. For InP junction FETs the measured transconductance varies from 80 to 100 ms/mm gate length. GaAs junction FETs show similar results with well behaved I-V characteristics.

Ternary organic solar cells based on two compatible PDI-based acceptors with an enhanced power conversion efficiency

Weng, Kangkang,Li, Chao,Bi, Pengqing,Ryu, Hwa Sook,Guo, Yikun,Hao, Xiaotao,Zhao, Dahui,Li, Weiwei,Woo, Han Young,Sun, Yanming The Royal Society of Chemistry 2019 Journal of Materials Chemistry A Vol.7 No.8

<P>Ternary solar cells have been proven to be an effective way to increase the power conversion efficiency (PCE) of organic solar cells (OSCs). Up to now, research effort has mostly focused on fullerene derivatives and acceptor-donor-acceptor (A-D-A) type non-fullerene acceptor-based ternary solar cells, while perylene diimide (PDI)-based ternary devices have been rarely studied. In this contribution, we introduced a new type of ternary solar cell based on a PDI-based small-molecule acceptor (PBI-Por) and a polymer donor (PTB7-Th) with a third PDI-based polymer acceptor (PDI-V). The introduction of PDI-V into the ternary blends not only broadens the absorption of blend films but also increases the electron mobilities. As a result, a high efficiency of 9.43% was obtained for the ternary OSC, which is 20% higher than that of the binary OSC. Detailed studies indicate that PDI-V showed good compatibility with PBI-Por in the blend films, which demonstrates a promising way to fabricate high-performance PDI-based OSCs.</P>

Characterization of the B cell receptor repertoire of patients with acute coronary syndrome

Weng Ruiqiang,Liu Sudong,Gu Xiaodong,Zhong Zhixiong 한국유전학회 2022 Genes & Genomics Vol.44 No.1

Background: Acute coronary syndrome (ACS) is a complex cardiovascular disease whose development involves the dysregulation of adaptive immune responses. Though it has been proven that T cells associate with inflammation in the development of ACS, the function of B cells in disease remains unclear. Objective: The aim of this study was to reveal the diversity of the B cell receptor (BCR) repertoire of patients with ACS. Methods: We conducted a pilot study to sequence the immune repertoire of peripheral blood mononuclear cells (PBMCs) from patients with ACS, including acute myocardial infarction (AMI) and unstable angina (UA), and quantitatively characterized BCR repertoires by bioinformatics analysis. Results: We found that patients with AMI and UA had lower BCR repertoire diversity compared with controls with normal coronary arteries (NCA). Lower percentages of productive unique BCR nt sequences and higher percentages of top 200 unique BCR sequences were identified in AMI and UA patients than NCA controls. Patients had various preferential usage of V and J genes from B cell clones in accordance with the disease severity of coronary arteries. AMI patients had distinct CDR3 amino acids, and their frequency differed among patients with ACS. Conclusions: Our results indicate that differential BCR signatures represent an imprint of distinct repertoires among ACS patients. This study thereby opens up the prospect of studying disease-relevant B cells to better understand and treat ACS.

Biosafety Risk Control Strategies in Laboratory Animal Research

Weng Shun-tai,Li Qu-wen,Gao Ya-dong,Qiu Yu-feng 한국산업안전보건공단 산업안전보건연구원 2024 Safety and health at work Vol.15 No.1

To understand biosafety's current situation in laboratory animal research and risk factors affecting occupational health. Compliance surveys were conducted by questionnaire via Questionnaire Star (an application app on the Internet) in Chinese. Thirty-nine anonymous questionnaires were collected. The surveyed institution has established 24 types of ABSL (Animal Biosafety Laboratory) and biosafety management organizations and systems equipped with safety equipment. Our study also suggests that the principal of the laboratory establishment fails to perform supervision and inspection responsibilities, the inappropriate design of the animal biosafety laboratory, non-standardized personnel training and health management, non-strict waste management, and insufficient emergency management. The administrative department and work units should address certain safety and occupational health risks in laboratory animal research. The author proposes control strategies based on organizational guarantee, personnel management, emergency management, etc., to help prevent risks and ensure occupational health. Due to regional limitations and small sample size, the results may not be generalisable to all parts of the world. However, some of the key common issues may also be present in other regions, so we believe that this research still has some relevance.

Roles of Formal Institutions and Social Capital in Innovation Activities: A Cross-Country Analysis

Weng Chang Lee,Siong Hook Law 연세대학교 동서문제연구원 2017 Global economic review Vol.46 No.3

This paper investigates the roles of formal institutions and social capital in countries’ innovation activities. The sample consists of 62 developed and developing countries, using the ordinary least squares robust standard error estimations, instrumental variable (IV) estimators, and quantile regression. The empirical results indicate that formal institutions and social capital complement one another in influencing countries’ innovations level. In terms of the relative importance of both in promoting innovation activities, the social capital has greater role compared to formal institutions. Furthermore, the empirical result suggests that innovation level tends to be higher in countries with higher social capital. We also use the quantile regression to estimate whether the relationship among formal institutions, social capital, and innovation differs at different points in the conditional distribution of innovation. The results demonstrate that formal institutions yield a significant positive impact only after exceeding in 50th quantile, whereas social capital do so at lower 10th quantile. Therefore, in addition to a policy focus on improving the formal institutions, countries with a low level of innovation should enrich social capital in their promotion of innovation activity.
