<P>Three new quaternary lithium metal tellurites, Li3MTe4O11 (M = Al, Ga, and Fe), have been synthesized through hydrothermal and solid-state reactions by heating a mixture of LiOH center dot H2O, TeO2, and M2O3. The structures of the title compounds have been determined by single-crystal and powder X-ray diffraction. Li3MTe4O11 reveal three-dimensional (3D) frameworks that consist of MO6 octahedra, TeO3 trigonal pyramids, and TeO4 polyhedra. The variable coordination mode of Te4+ within the framework leads to the formation of 1D channels that host Li+ cations on both tetrahedral and octahedral sites. The bulk and grain boundary Li+ ion conductivities for a Li3FeTe4O11 pellet in open air are estimated to be 1.0 x 10(-4) and 2.7 x 10(-6) S cm(-1), respectively, at room temperature from the impedance profile analysis. A lower activation energy of 19.9 kJ mol(-1) is obtained for the system, which is similar to that of Li10GeP2S12 (24 kJ mol(-1)). Detailed characterizations such as thermal, spectroscopic, and magnetic properties for the reported materials are also reported.</P>

Objective: Hypoactivity in the reward system among patients with attention deficit hyperactivity disorder (ADHD) is a well-known phenomenon. Whether the activity in the reward pathway is related to harm avoidance, such as in sensitivity to punishment, is unclear. Evidence regarding the potential difference between ADHD patients and controls in terms of this association is scarce. Methods: Event-related functional magnetic resonance imaging was conducted on subjects performing the Iowa gambling test. Fourteen adults with ADHD and 14 controls were enrolled in the study. Results: Harm avoidance was found to be positively correlated with the activities of the bilateral orbitofrontal cortex and right insula in individuals with ADHD. A group difference was also confirmed. Conclusion: Understanding the roles of harm avoidance and brain activation during risk tasks is important.
Path Loss Exponent Estimation for Indoor Wireless Sensor Positioning
( Yu-sheng Lu ),( Chin-feng Lai ),( Chia-cheng Hu ),( Yueh-min Huang ),( Xiao-hu Ge ) 한국인터넷정보학회 2010 KSII Transactions on Internet and Information Syst Vol.4 No.3
Rapid developments in wireless sensor networks have extended many applications, hence, many studies have developed wireless sensor network positioning systems for indoor environments. Among those systems, the Global Position System (GPS) is unsuitable for indoor environments due to Line-Of-Sight (LOS) limitations, while the wireless sensor network is more suitable, given its advantages of low cost, easy installation, and low energy consumption. Due to the complex settings of indoor environments and the high demands for precision, the implementation of an indoor positioning system is difficult to construct. This study adopts a low-cost positioning method that does not require additional hardware, and uses the received signal strength (RSS) values from the receiver node to estimate the distance between the test objects. Since many objects in indoor environments would attenuate the radio signals and cause errors in estimation distances, knowing the path loss exponent (PLE) in an environment is crucial. However, most studies preset a fixed PLE, and then substitute it into a radio propagation loss model to estimate the distance between the test points; such method would lead to serious errors. To address this problem, this study proposes a Path Loss Exponent Estimation Algorithm, which uses only four beacon nodes to construct a radio propagation loss model for an indoor environment, and is able to provide enhanced positioning precision, accurate positioning services, low cost, and high efficiency.

Objective: To create genetically modified goat as a biopharming source of recombinant human lacotoferrin (hLF) with transcription activator-like effector nucleases. Methods: TALENs and targeting vector were transferred into cultured fibroblasts to insert hLF cDNA in the goat beta-lactoglobulin (BLG) locus with homology-directed repair. The gene targeted efficiency was checked using sequencing and TE7I assay. The bi-allelic gene targeted colonies were isolated and confirmed with polymerase chain reaction, and used as donor cells for somatic cell nuclear transfer (SCNT). Results: The targeted efficiency for BLG gene was approximately 10%. Among 12 Bi-allelic gene targeted colonies, five were used in first round SCNT and 4 recipients (23%) were confirmed pregnant at 30 d. In second round SCNT, 7 (53%), 4 (31%), and 3 (23%) recipients were confirmed to be pregnant by ultrasound on 30 d, 60 d, and 90 d. Conclusion: This finding signifies the combined use of TALENs and SCNT can generate bi-allelic knock-in fibroblasts that can be cloned in a fetus. Therefore, it might lay the foundation for transgenic hLF goat generation and possible use of their mammary gland as a bioreactor for large-scale production of recombinant hLF.

In recent years, the ripple-based constant on-time (RBCOT) control scheme for voltage regulators has been adopted in many applications because of its high efficiency feature under light-load conditions. However, a RBCOT control suffers from output-voltage offset problem. Therefore, an offset correction circuit (OC) is often added to the basic RBCOT scheme to correct the problem. In the OC circuit, there is a RC filter. The size of this RC filter not only affects the circuit stability and converter transient responses but also directly affects the controller chip size/cost. The main focus of the present paper is to investigate the relationship between the RC filter value and the feedback stability so that RC value can be minimized while avoiding circuit instability. A time-domain analysis approach is proposed to model OCRBCOT scheme for a buck converter configuration. Experimental and simulation results are given for verification.
Finger Vein Recognition Using Generalized Local Line Binary Pattern
( Yu Lu ),( Sook Yoon ),( Shan Juan Xie ),( Jucheng Yang ),( Zhihui Wang ),( Dong Sun Park ) 한국인터넷정보학회 2014 KSII Transactions on Internet and Information Syst Vol.8 No.5
Finger vein images contain rich oriented features. Local line binary pattern (LLBP) is a good oriented feature representation method extended from local binary pattern (LBP), but it is limited in that it can only extract horizontal and vertical line patterns, so effective information in an image may not be exploited and fully utilized. In this paper, an orientation-selectable LLBP method, called generalized local line binary pattern (GLLBP), is proposed for finger vein recognition. GLLBP extends LLBP for line pattern extraction into any orientation. To effectually improve the matching accuracy, the soft power metric is employed to calculate the matching score. Furthermore, to fully utilize the oriented features in an image, the matching scores from the line patterns with the best discriminative ability are fused using the Hamacher rule to achieve the final matching score for the last recognition. Experimental results on our database, MMCBNU_6000, show that the proposed method performs much better than state-of-the-art algorithms that use the oriented features and local features, such as LBP, LLBP, Gabor filter, steerable filter and local direction code (LDC).

Yu Lu 국제문화기술진흥원 2024 International Journal of Advanced Culture Technolo Vol.12 No.1
The growth of the national economy and the improvement of household consumption have had a profound impact on the design of children's food packaging. As household economic conditions improve, children's consumption needs and habits are becoming more diverse. Especially in the field of children's food, food packaging still plays a key role, not only to protect the freshness and safety of food, but also to create a pleasant and fun emotional atmosphere in the minds of children. The aim of this study is to explore the close link between emotional interaction and the children's food market, and to study approaches to children's food packaging design to provide beneficial insights to promote sales and meet changing consumer needs.
