Role of medial temporal lobe in extensive retrieval of task‐related knowledge

The role of medial temporal lobe (MTL) in deep semantic processing was examined in a triple semantic judgment task in which subjects were asked to decide which one of the two bottom words was more semantically fit to the top word. By changing the number of bottom words that are semantically related to the top word, we can disassociate effects of reactivating the “old” semantic associations and effects of establishing “new” semantic associations on the MTL. The results of event‐related fMRI analysis indicated that MTL was more activated in the retrieval of old semantic associations than in the establishment of new semantic associations. The function of MTL in this semantic judgment task was explained as subserving the process of extensive retrieval of task‐related knowledge. Hippocampus 2002;12:487–494. © 2002 Wiley‐Liss, Inc.
Detection and tracking targets under low SNR

Target tracking in the time is a difficult problem of dynamic state estimation; the problem is more complex in a low signal to noise ratio (SNR) or in high clutter conditions. An efficient approach for target detection and tracking under low signal to noise ratio (SNR) conditions is the Track-Before-Detect (TBDF) filter. This paper proposes to use the TBD method based on particle filtering includes unthresholded data and a binary variable of the existence of the target in the estimating target state for two motion model. Using simulations it is shown that with this method, it is possible to detect and track the target in low signal to noise ratio.
Efficacy of an insole shoe wedge and augmented pressure sensor for gait training in individuals with stroke: a randomized controlled trial

Objective: To determine whether external feedback to promote symmetrical weight distribution during standing and walking would improve gait performance and balance in people with stroke. Design: Randomized, controlled, assessor-blinded trial. Setting: Rehabilitation unit and physical therapy department. Subjects: Thirty-five individuals with stroke (mean (SD) age = 53.0 (9.3) years) were randomly assigned to an experimental (n = 17) or control group (n = 18). Time post stroke was less than six months for most subjects (n = 27, 77%). Interventions: Subjects participated in 15 rehabilitation sessions including 30 minutes of gait retraining per session. During gait retraining, the experimental group used an insole shoe wedge and sensors set-up (I-ShoWS) while the control group received a conventional programme. The I-ShoWS set-up consisted of a wedge insole and a footswitch for the non-paretic leg and a pressure sensor on the paretic leg. Outcome measures: Gait speed, step length and single support time asymmetry ratio, balance and amount of load on paretic leg during stance were evaluated twice: one day before and after training. Results: The experimental group demonstrated significant increase in standing and gait symmetry compared with the control group (P < 0.05). They demonstrated 3 times greater improvement in gait speed than the control group (P = 0.02). Balance improvement was significantly greater for the experimental than for the control group (P < 0.05). Conclusion: Gait retraining using the I-ShoWS set-up was more effective in restoration of gait speed, standing and walking symmetry and balance than a conventional treatment programme. These results indicate the benefit of implementing feedback during gait retraining.
ASSESSING THE STRUCTURE OF A CONCEPT MAP

This paper presents a framework for the evaluation of concept maps. We focus on supporting the student in dealing with ill-structured and complex problems. We argue that these problems require the application of the modularity approach. In view of this, the paper describes ways of providing student support for the implementation of this approach within the context of a concept mapping activity. As a basis we make use findings from the field of brain science and mathematical concepts and tools from the field of network theory, in order to present specific evaluation methods, the further development of which we consider extremely promising.
Studying Safe Online Banking Behaviour: A Protection Motivation Theory Approach

In this paper, a conceptual research model is proposed to study safe online banking behaviour. The Protection Motivation Theory functions as the core of the model. The model is extended with additional variables, making it suitable for the online banking context. The coping perspective, which is central to the Protection Motivation Theory, seems to be valuable to study behaviour in information systems. By taking a cognitive behavioural perspective, it can be examined how individuals cope with threats, which may contribute to the development of effective intervention programs aimed at safe online banking.
Time domain probe insertion to find steady state of strongly nonlinear high-Q oscillators

Probe insertion is traditionally used in the frequency domain to increase robustness of the harmonic balance method and avoid the DC degenerate solution. This technique evidences several good properties, for instance when simulating oscillators that are based on high quality factor resonators or AC coupled ones. In this paper the probe insertion technique is extended to the time domain, allowing the application of the shooting method to a wider class of circuits including for example crystal oscillators. Time domain methods, such as shooting, are superior in the simulation of strongly nonlinear, and, thanks to a recent extention, mixed analog/digital circuits. Moreover, time domain probe insertion can be used to find multiple steady state solutions and check their stability properties, without the need to compute the eigenvalues of the monodromy matrix.
Screening of selected plant extracts for in vitro inhibitory activity on Human Immunodeficiency Virus

As part of our screening of anti‐AIDS agents from natural sources, extracts of 15 medicinal plants widely used in the folk medicines of North America and Europe were evaluated in vitro. Most of the extracts tested were relatively nontoxic to human lymphocytic MT‐2 cells, but only the extracts of Hysopp officinalis and Dittrichia viscosa exhibited anti‐HIV activity in an in vitro MTT assay. The 50% hydroalcohol extract of Hysopp officinalis and the aqueous extract of Dittrichia viscosa showed inhibitory effects against HIV‐1 induced infections in MT‐2 cells at concentrations ranging from 50 to 100 μg/mL and 25 to 400 μg/mL, respectively. Both extracts showed no appreciable cytotoxicity at these concentrations. Copyright © 2002 John Wiley & Sons, Ltd.
Improvement of compact terminal antenna performance by incorporating open-end slots in ground plane

This letter describes a new idea of increasing operational bandwidth of a compact planar inverted F antenna (PIFA) by introducing open-end slots in the ground plane under the radiating patch. The slots are not in the way of active modules of a wireless transceiver and thus the proposed antenna size reduction method is attractive from the point of view of practical implementation.
Rapid attachment of adipose stromal cells on resorbable polymeric scaffolds facilitates the one‐step surgical procedure for cartilage and bone tissue engineering purposes

The stromal vascular fraction (SVF) of adipose tissue provides an abundant source of mesenchymal stem cells. For clinical application, it would be beneficial to establish treatments in which SVF is obtained, seeded onto a scaffold, and returned into the patient within a single surgical procedure. In this study, we evaluated the suitability of both a macroporous poly(L‐lactide‐co‐caprolactone) and a porous collagen type I/III scaffold for this purpose. Surprisingly, cell attachment was rapid (∼10 min) and sequestered the majority of adipose stem cells, as deduced from colony‐forming unit assays. Proliferation occurred in both polymeric scaffolds. Upon chondrogenic induction, up‐regulation of chondrogenic genes, production of glycosaminoglycans, and accumulation of collagen type II was observed, indicating differentiation of scaffold‐attached SVF cells along the chondrogenic lineage. Osteogenic differentiation was achieved in both scaffold types, as visualized by up‐regulation of osteogenic genes, increase of alkaline phosphatase production over time, and accumulation of bone sialoprotein and osteonectin. In conclusion, this study identifies both poly(L‐lactide‐co‐caprolactone) and collagen type I/III as promising scaffold materials for rapid attachment of adipose stem cell‐like (stromal) cells, enhancing the development of one‐step surgical concepts for cartilage and bone tissue engineering. © 2011 Orthopaedic Research Society Published by Wiley Periodicals, Inc.

Design and implementation of a highly efficient pure sine-wave inverter for photovoltaic applications

Due to rapid growth of photovoltaic (PV) power generation, highly efficient and cost effective pure sine wave inverters are greatly demanded in the local market. Based on the simulation result in PSIM software, a low ripple and almost 97% efficient single-phase pure sine-wave inverter for PV application has been designed and implemented which has a total harmonic distortion (THD) of less than 0.6%. Sinusoidal pulse width modulation (SPWM) generated by PIC16F876 Microcontroller is used to control the switching of the inverter power circuit. Error in the output signal is minimized for both inductive and capacitive load by employing a closed loop control scheme that ensures suitable harmonic elimination technique to achieve better performance of the inverter output waveform. To reduce cost we have used low frequency transformer that is available in the local market, which aids to make our design cheaper compared to the design that is based on high frequency transformer. To validate simulation results a prototype has been constructed and tested. Simulation and practical results were compared and both the results conform to each other.
Localization and map building using laser range sensors in outdoor applications

This paper presents the design of a high accuracy outdoor navigation system based on standard dead reckoning sensors and laser range and bearing information. The data validation problem is addressed using laser intensity information. The beacon design aspect and location of landmarks are also discussed in relation to desired accuracy and required area of operation. The results are important for simultaneous localization and map building applications (SLAM), since the feature extraction and validation are resolved at the sensor level using laser intensity. This facilitates the use of additional natural landmarks to improve the accuracy of the localization algorithm. The modelling aspects to implement SLAM with beacons and natural features are also presented. These results are of fundamental importance because the implementation of the algorithm does not require the surveying of beacons. Furthermore we demonstrate that by using natural landmarks accurate localization can be achieved by only requiring the initial estimate of the position of the vehicle. The algorithms are validated in outdoor environments using a standard utility car retrofitted with the navigation sensors and a 1 cm precision Kinematic GPS used as ground truth. © 2000 John Wiley & Sons, Inc.
Fairness uplink packet scheduling strategies in LTE networks

The scheduler was designed for uplink systems of LTE networks in this thesis. It makes different services correspond to different data streams to provide different QoS (Quality of Service) to various applications. For the broadest scope of coverage and to reduce the cost of terminal and power consumption, priority assignments and resource allocations were taken into consideration when the scheduler was designed. Limiting the users with lower priority settings in the scheduling algorithm is efficacious for regulating the order of resource allocations made to the users. The goal is to achieve the highest system performance by enhancing transmission efficacy and satisfying the fairness of resource allocation at the same time. Finally, the scheduler avoids connection latency and starvation related to lower priority resource allocation.
Tyrphostin AG1478 Inhibits Encephalomyocarditis Virus and Hepatitis C Virus by Targeting Phosphatidylinositol 4-Kinase IIIα

ABSTRACT Encephalomyocarditis virus (EMCV), like hepatitis C virus (HCV), requires phosphatidylinositol 4-kinase IIIα (PI4KA) for genome replication. Here, we demonstrate that tyrphostin AG1478, a known epidermal growth factor receptor (EGFR) inhibitor, also inhibits PI4KA activity, both in vitro and in cells. AG1478 impaired replication of EMCV and HCV but not that of an EMCV mutant previously shown to escape PI4KA inhibition. This work uncovers novel cellular and antiviral properties of AG1478, a compound previously regarded only as a cancer chemotherapy agent.
Corporate Strategy, Personnel Dependence and Evolution of Organizational Flexibility

This paper firstly induces three fields of former research and the research gap and defines the personnel flexibility. Then corporate flexibility is divided into five dimensions and the mechanism of tradeoff and promotion of personnel flexibility to others is discussed, which proves the core status of personnel flexibility in corporate flexibility. Finally, personnel flexibility is constructed from four respects through factorization.
Dynamic Interrupt Controller and Conflict Management for Transactional Memory in Embedded System

In hardware transactional memory system, selecting an interrupt handling mechanism is the one of problems. To handle interrupts occur in transactions, all systems need special mechanisms but these require more hardware or software resources, so this is not acceptable to the embedded system that has limitations. In this paper, we proposed interrupt handling process and interrupt controller that distributes interrupts to proper core in the system. Then we present performance metrics for the system and how transactional memory policies affect to the metrics. Simulation results show that roughly 80% of interrupts that occur in transaction can be improved and eager conflict detection, polite and polka contention managements are proper polices for the proposed system.

This paper introduces the resource allocation model which is based on the Continuous Double Auction(CDA) mechanism and the pricing strategy of the supplier and the demander under cloud computing environment.After the law of the failure of resources nodes is analyzed,it promotes a dynamic resource allocation strategy which is based on the CDA mechanism and the credibility of the nodes.Matlab simulation results show that the strategy can ensure the creditability of the resources,improve the operation efficiency and maximize the Quality of Service(QoS) when dynamically providing resources.
Lifetime trauma, personality traits, and health: A pathway to midlife health status.

OBJECTIVE This study investigated whether lifetime experience of trauma is related to personality through instrumental and reactive trait processes, and whether lifetime trauma is a mechanism underlying the association between childhood conscientiousness and objectively assessed adult physical health. METHOD Participants (N = 831) were 442 women and 389 men from the Hawaii longitudinal study of personality and health. Teacher assessments of personality were obtained when the participants were in elementary school. Self-reported adult personality assessments, lifetime histories of trauma experience, and objectively assessed physiological dysregulation were obtained between ages 45-55. RESULTS Women tended to report more high-betrayal trauma than men, whereas men reported more low-betrayal trauma than women. Women who were judged by their teachers to be less agreeable and less conscientious in childhood reported more lifetime trauma, suggesting instrumental trait processes. For both genders, neuroticism and openness/intellect/imagination in adulthood, but not in childhood, were associated with lifetime trauma, suggesting reactive trait processes. For both genders, trauma experience was correlated with dysregulation and with Body Mass Index (BMI). The indirect paths from childhood conscientiousness to adult dysregulation and BMI through total teen and adult trauma were significant for women, but not for men (indirect effect for women's dysregulation = -.025, p = .040, 95% confidence interval [CI] = -.048, -.001; indirect effect for women's BMI = -.037, p = .009, 95% CI = -.067, -.008). CONCLUSION Teen and adult trauma experience appears to be a hitherto unidentified mechanism in women underlying the association between conscientiousness and health. (PsycINFO Database Record
Bacterial community composition and colored dissolved organic matter in a coastal upwelling ecosystem

The aim of the present study was to correlate changes in dissolved organic matter (DOM) composition, as characterized through humic- and protein-like fluorescence, with changes in the abundance of major bacterial groups (Alphaproteobacteria, Betaproteobacteria, Gammapro- teobacteria and Bacteroidetes) and bacterial activity in an upwelling system during the season of low productivity. Sampling was conducted under 2 contrasting periods characterized by low (February) and high (October) precipitation. In October, the mean humic-like DOM fluorescence in surface waters (3.1 ppb equivalents of quinine sulphate (ppb QS)) was higher than the annual average for this coastal zone (2.2 ppb QS), which was attributed to enhanced continental runoff. Alphaproteobac- teria and Bacteroidetes were the most abundant groups, accounting for about 13 and 16% of total bacterial abundance, respectively. Betaproteobacteria were detectable only during the rainy period, accounting for 2 to 9% of total bacterial abundance. The bulk dissolved organic carbon concentration similarly explained the relative abundance of Alphaproteobacteria, Betaproteobacteria and Gamma- proteobacteria (ca. 50% of total variability). By contrast, a strong correlation was found between the humic-like DOM fluorescence and the relative abundance of the Betaproteobacteria group, explain- ing 68% of the total variability. Multivariate linear regression analyses revealed that the relative abundance of Betaproteobacteria has the greatest influence on bacterial carbon fluxes, explaining 61 and 65% of bulk bacterial activity and biomass variability, respectively. Despite their relatively low abundance, Betaproteobacteria might play a relevant biogeochemical role in this coastal transition ecosystem during the low productivity period as allochthonous DOM consumers.
Fast reroute for stateless multicast

Multicast applications such as real-time streaming and video/teleconferencing tolerate delay and packet loss poorly. As a consequence, multicast routing and forwarding should offer flexibility and resiliency for them. In this paper, we introduce fast reroute methods for LIPSIN, a novel Bloom filter based multicast forwarding fabric. We propose two different algorithms, both capable of rerouting traffic immediately after the failure is detected, keeping service disruption at minimum. The two solutions give flexibility to operators by allowing trade-offs between bandwidth and configuration complexity. Finally, we give guidelines about the applicability of our methods by conducting simulations.
Measuring Outcomes using the Australian Therapy Outcome Measures for Occupational Therapy (AusTOMs-OT): Data Description and Tool Sensitivity

Although there is increasing demand for greater accountability from occupational therapists for the outcomes of their practice, there are few quick, simple and psychometrically sound tools available to measure these outcomes. This paper reports on the first data collection exercise using a new outcome measure, the Australian Therapy Outcome Measures for Occupational Therapy (AusTOMs-OT). The aims of this paper are to present the scales, describe the data set and examine whether the scales are sufficiently sensitive to detect change over time in client status. Data were collected with 466 clients at 12 metropolitan and rural health care facilities using the 12 AusTOM-OT scales, which rate the client in relation to the four domains of Impairment, Activity limitation, Participation restriction and Distress/wellbeing. The findings indicated that the most frequently used scales were Self-care, Upper limb use, Transfers and Functional walking and mobility, and that all scales were successful in demonstrating statistically significant client change over time. The AusTOMs-OT can be used to document client outcomes in relation to four important practice domains and thus be of value in research and quality assurance activities seeking to provide evidence that occupational therapy does make a difference to the lives of clients.
Predicting Rapid Clinical Progression in Amnestic Mild Cognitive Impairment

Background/Aims: We investigated whether an initial neuropsychological assessment could predict rapid progression over 12 months, from amnestic mild cognitive impairment (aMCI) to Alzheimer’s disease (AD). Methods: A longitudinal study compared the neuropsychological profiles of 27 normal controls and 18 aMCI patients at baseline and 12 months. Results: At 12 months, 24 control subjects followed up remained cognitively normal. 7 aMCI patients (6 multiple-domain aMCI and 1 single-domain aMCI) progressed to AD, and 11 were non-progressors. Prognosis was best captured by a combination of associative learning, the paired associate learning task (PAL), and global cognition, the Addenbrooke’s Cognitive Examination (ACE). Conclusion: The PAL and ACE can sensitively detect meaningful differences in scores at baseline and may be used as prognostic indicators. Multiple-domain aMCI patients progressed rapidly to AD and may be more usefully labelled as early stage AD.
Effect of chronic renal failure on the expression and function of rat intestinal P-glycoprotein in drug excretion.

BACKGROUND In chronic renal failure, the renal excretion of certain drugs is dramatically reduced. To determine whether other routes of drug elimination, such as secretion through the intestinal barrier by intestinal P-glycoprotein can be altered, we compared P-glycoprotein activity, P-glycoprotein protein content, and P-glycoprotein mRNA levels in intestine of control and chronic renal failure rats. METHODS Chronic renal failure was surgically induced in rats by partial (7/8) nephrectomy. After 5 weeks, intestinal transport of rhodamine 123, a P-glycoprotein substrate, was carried out using an in vitro model of everted gut sacs. P-glycoprotein protein content was quantified by enzyme-linked immunosorbent assay and P-glycoprotein mRNA expression was evaluated by semi-quantitative reverse transcriptase polymerase chain reaction. RESULTS A decrease of intestinal rhodamine 123 transport was observed in chronic renal failure rats, pointing to an inhibition of P-glycoprotein activity. Transport was inhibited in both sham-operated rats and rats with chronic renal failure by verapamil and cyclosporin A, but relative inhibition vs baseline was less marked in chronic renal failure than in sham-operated rats. In contrast, no significant differences in levels of P-glycoprotein protein or mRNA were observed between the two groups. CONCLUSIONS Intestinal secretion of rhodamine 123 is mainly mediated by P-glycoprotein. It was reduced in rats with chronic renal failure, reflecting reduced intestinal drug elimination via a decrease in P-glycoprotein transport activity rather than via protein underexpression.
