CTGaming: A Problem-Oriented Registry for Clinical TeleGaming Rehabilitation and Intervention

A clinical telegaming registry, called CTGaming, has been added as a new Problem-Oriented Registry of Tags And Labels (PORTAL) to the collection of prototype PORTAL registries for ongoing development of the PORTAL-DOORS System (PDS). As a distributed system of interacting PORTAL registries and DOORS directories, PDS provides metadata management services for who-what-where metadata about both online and offline resources. For the CTGaming PORTAL, the scope of the problem-oriented specialty domain for the registry encompasses gaming in physiotherapy, rehabilitation and intervention via telecare, and in general, diagnostic and therapeutic telegaming. This new PORTAL registry has also been incorporated into the design of an existing clinical telegaming system (CTGS). Operating as an adaptive gaming application for telerehabilitation, the CTGS functions either locally in a clinical care setting or remotely in a telecare setting in patients’ homes. Operating in concert with the CTGS, the CTGaming PORTAL has been established as a host for metadata representations of resources in the field of clinical telegaming with metadata representations for resources relevant to the CTGS served upon request. These resources may include external resources from the public web as well as internal resources such as telegaming session data from the private medical records associated with the CTGS.
Continuous-variable teleportation of a negative Wigner function

Teleportation is a basic primitive for quantum communication and quantum computing. We address the problem of continuous-variable (unconditional and conditional) teleportation of a pure single-photon state and a mixed attenuated single-photon state generally in a nonunity-gain regime. Our figure of merit is the maximum negativity of the Wigner function, which demonstrates a highly nonclassical feature of the teleported state. We find that the negativity of the Wigner function of the single-photon state can be unconditionally teleported for an arbitrarily weak squeezed state used to create the entangled state shared in teleportation. In contrast, for the attenuated single-photon state there is a strict threshold squeezing one has to surpass to successfully teleport the negativity of its Wigner function. The conditional teleportation allows one to approach perfect transmission of the single photon for an arbitrarily low squeezing at a cost of decrease of the success rate. In contrast, for the attenuated single photon state, conditional teleportation cannot overcome the squeezing threshold of the unconditional teleportation and it approaches negativity of the input state only if the squeezing increases simultaneously. However, as soon as the threshold squeezing is surpassed, conditional teleportation still pronouncedly outperforms the unconditional one. The main consequences for quantum communicationmore » and quantum computing with continuous variables are discussed. « less
New process and pixel structure of an SOI-CMOS imager

We present architecture, process design and results from test pixels of a new Active Pixel Sensor (APS) imager implemented in 0.8 /spl mu/m SOI-CMOS technology. The conventional partially-depleted SOI-CMOS process has been altered by adding one lithography for buried oxide window opening and two implants into the handle wafer. Results on front illuminated photodiode arrays show that the Quantum Efficiency (QE) are 2-10x improved in peak and red spectral response, respectively, compared to bulk APS imagers. Dark current tests on photodiodes and pixels indicate a periphery-dominated and voltage-dependent leakage current of 5-20 nA/cm/sup 2/ at 3V. Pixel linearity error of /spl sim/4% is observed at 80% of saturation. Test results indicate directions for further reduction of the dark current.
Diffusion-limited aggregation: A kinetic critical phenomenon?

Diffusion-limited aggregation (DLA) is a model which represents noisy growth limited by diffusion. This process is quite common in nature and the simple algorithm gives a good representation of the large-scale structure of many natural objects. The clusters grown in the computer and the real objects in question are tenuous and approximately self-similar. A good deal is known about the algorithm, but a complete theory is not yet available. I review the current state of knowledge about the model, its applications and theoretical analysis of the results.

The Pedagogical Applications of Mobile-Assisted Language Learning (MALL) in Improving the Iranian EFL Learners' Oral Performance

In the era of globalization, the use of mobile technologies changed the teaching-learning process in the various educational levels to make the pedagogy natural, vivid and interactive. Implementing global technologies in the educational contexts not only promote the level of teaching but also motivate the learners in providing information by means of innovative and attractive tasks. The appropriate use of mobile-related technologies in and outside classroom facilitates the teaching-learning process and helps the students learn the language better and gain information in depth. Language instructors can create the suitable environment for teaching by applying technology. The present article deals with the effective use of mobile-related technologies in the Iranian EFL contexts. The learners were divided into two groups of experimental and control, each group consisted of 30 students to assess the validity and utility of MALL in an English language institute. The results showed that the experimental group outperformed the control group and learners' fluency improved in their speaking skill.
The VVV-SkZ_pipeline: an automatic PSF-fitting photometric pipeline for the VVV survey

We present the VVV-SkZ pipeline, a DAOPHOT-based photometric pipeline, created to perform PSF-fitting photometry of "VISTA Variables in the V´oa Lctea" (VVV) ESO Public Survey data. The pipeline replaces the user avoiding repetitive interaction in all the operations, retaining all of the benefits of the power and accu- racy of the DAOPHOT suite. The pipeline provides an astrometrized photometric catalog reliable up to more than 2 magnitudes brighter than the saturation limit, where other techniques fail. It also produces deeper and more accurate photometry. These achievements allow the VVV-SkZ pipeline to produce data well anchored to the selected standard photometric system and analyze important phenomena (i.e. TRGB, RGB slope, HB morphology, RR Lyrae), that other methods are not able to manage.
Cryopreservation of buffalo (Bubalus bubalis) semen: Current status and future prospective

Most progress in improving reproductive efficiency of buffalo can be made by accurate estimation of the fertility of males and their selective use. Because of the major impact of individual males on multiple pregnancies and the ability to estimate fertility of males, more emphasis is placed on evaluating males. Spermatozoa were the first mammalian cells to be cryopreserved successfully due to the serendipitous discovery of the cryoprotective effect of glycerol. The development of cryopreservation protocols for the bull to be used for AI in the dairy industry began in the 1950s. Cryopreservation of semen has permitted the rapid expansion of reproductive technology such as artificial insemination. Advances in the reproductive biotechnology particularly cryopreservation of semen paved the way for better freezing of buffalo semen which was earlier considered as problematic. However, cryopreservation induces damage to all sperm compartments. Moreover, there is also variable degree of morphological, physiological and biochemical alterations in remaining population of live spermatozoa making them unsuitable for optimum fertility. Till today, there is no single objective test to evaluate the fertility of bull. The development of fertility markers to identify bulls of high breeding values at young age represents a remarkable way for achieving genetic gain in dairy farming. This review summarizes the developmental path of semen cryopreservation in buffalo along with the recent development in this field and critical gap therein.
IDENTIFIKASI PARAMETER OPTIMAL GAUSSIAN MIXTURE MODEL

One of the problems in the speaker identification system is a feature that generated less resistant to noise. In the noisy environment, the speaker identification system performance can drop significantly. It is caused by environmental differences when training and testing. One feature extraction method used to identify the speaker and sensitive to noise is Mel frequency cepstral coefficient (MFCC). In a clean environment, the performance generated by MFCC method is very high, but dropped dramatically when in the noisy environment. In this study, we propose to modify the MFCC method using endpoint detection residues. Results of endpoint detection algorithm is speech and nonspeech (residue). Nonspeech or residues are usually not used in the next process. At the noisy signal, the residue of endpoint detection algorithm is filled by the noise itself so that it can be used as information noise. The residue is extracted to get the magnitude of the noisy signal. Magnitude of the noisy signal is used to remove noise on the main signal or speech. The experiments using five types of noise with seven levels of SNR. The type of noise that used is f16, hfchannel, pink, volvo, and white. While the level of SNR that used is clean, 25, 20, 15, 10, 5, and 0 dB. Experimental results show that the proposed method superior to the majority of the speakers. In addition the proposed method is also superior to all types of noise and superior in nearly all levels of SNR. The proposed method shows the average accuracy 14.69% higher than MFCC, 2.74% higher than MFCC+Spectral Subtraction (SS), and 6.4% higher than MFCC+wiener.
Nucleolus Modulates the Shuttle of Telomere Components between Nucleolus and Telomere

Nucleolus was first described about two centuries ago, functioning as the factory of rRNA transcription, processing and assembly of ribosome. While recently studied reported that it can also participate in other bioprocesses such as cell cycle arrest, cellular senescence, protein sub-nuclear distribution and cancer cell proliferation, except its ribosome role. Shelterin as well telomerase is critical for the integration and length maintenance. Here are some studies found that some telomere components like telomere was also accumulated in nucleolus and its retention in nucleolus was regulated by nucleolus protein which is indispensable for the matured of telomerase. Our recent study also demonstrated that TRF2, a member of shelterin, also settled in nucleolus and its telomere protection function was affected by the shuttling between nucleolus and telomere. Here, we review the recent research on the communication between nucleolus and telomere with emphasis on the potential and valuable research direction.
Two coaches operating as a ‘learning pair’

Whilst an established aid to personal development, coaching is still in its early stages of maturity. So too, outside of the field of education, is the concept of learning teams. This paper concerns coach development via two complementary coaches working as a learning team when conducting live coaching sessions. It proposes a way in which practitioners might enhance their continuous professional development - and therefore their service to their clients - by making an increasingly efficient and effective use of their everyday work. It is not concerned with team coaching, although many of the principles will be the same.
Modeling of mechanical properties of as-cast Mg-Li-Al alloys based on PSO-BP algorithm

Artificial neural networks have been widely used to predict the mechanical properties of alloys in material research. This study aims to investigate the implicit relationship between the compositions and mechanical properties of as-cast Mg-Li-Al alloys. Based on the experimental collection of the tensile strength and the elongation of representative Mg-Li-Al alloys, a momentum back-propagation (BP) neural network with a single hidden layer was established. Particle swarm optimization (PSO) was applied to optimize the BP model. In the neural network, the input variables were the contents of Mg, Li and Al, and the output variables were the tensile strength and the elongation. The results show that the proposed PSO-BP model can describe the quantitative relationship between the Mg-Li-Al alloy's composition and its mechanical properties. It is possible that the mechanical properties to be predicted without experiment by inputting the alloy composition into the trained network model. The prediction of the influence of Al addition on the mechanical properties of as-cast Mg-Li-Al alloys is consistent with the related research results.
Preserving Anti-Corrosion Properties of Epoxy Based Coatings Simultaneously Exposed to Humidity and UV-Radiation Using Nano Zinc Oxide

Nano zinc oxide-containing epoxy-based coatings were prepared by co-deposition of zinc oxide nano particles and epoxy-based cathodic electrodeposition paint. The films were exposed to UV radiation for different periods and the corrosion resistance properties of the exposed films were evaluated by electrochemical impedance spectroscopy. It was found that the nano zinc oxide stabilized coatings maintain their protective properties even after a prolonged exposure to UV light. The more prolonged retention of protection properties of the coating was assigned to the morphology of the film containing nano ZnO after exposure to UV light. Nano ZnO stabilized coatings show a uniform degradation of the film surface while non-stabilized coating exhibit deep cracks which results in deterioration of the film integrity. UV exposure of non-stabilized films was found to result in formation of deep cracks and non-uniform photodegradation in epoxy coating.
Visual object retrieval by graph features

Our approach addresses the well-known problem of adding spatial information to the standard bag-of-visual-words (BoVW) approach. To that end, a set of graphs descriptors are constructed for the entire image or for local image regions. These descriptors are then incorporated into a bag-of-visual-words approach, leading to a method called bag-of-bag-of-visual-words (BBoVW).
The relationship between learning approaches and learning outcomes: a study of Irish accounting students

The higher education literature demonstrates that a student's approach to learning is a critical factor in determining the quality of the learning outcome. This is the first study undertaken in an Irish context which examines the relationship between accounting students' approaches to learning and their learning outcomes. The Approaches and Study Skills Inventory for Students (ASSIST) is used to measure the approaches to learning adopted by first year students in their study of management accounting. Students' learning outcomes are represented by their performance in the various assessment components of that module. Gender differences are specifically considered in this study. The analysis reveals that for the full group the deep and strategic approaches are positively associated with high academic performance and the instrumental approach is associated with poor performance. This relationship exists for female students but, surprisingly, there is little evidence of a relationship between performance and learning approaches for male students. This may be explained by male students failing to effectively report their actual approach to learning.
The impact of intellectual capital on firms' market value and financial performance

Purpose – Intellectual capital (IC) shows a significant growing acceptance as a worthy topic of academic investigation and practical implication. The purpose of this study is to examine the impact of IC on firms' market value and financial performance.Design/methodology/approach – The empirical data were drawn from a panel consisting of 96 Greek companies listed in the Athens Stock Exchange (ASE), from four different economic sectors, observed over the three‐year period of 2006 to 2008. Various regression models were examined in order to test the hypotheses included in the proposed conceptual framework.Findings – Results failed to support most of the hypotheses; only concluding that there is a statistically significant relationship between human capital efficiency and financial performance. Despite the fact that IC is increasingly recognised as an important strategic asset for sustainable corporate competitive advantage, the results of the present study give rise to various arguments, criticism and furthe.
Design and Fabrication of an Auto-Tilting Car

The narrow track cars have an increased rolling tendency. So, there is a need to develop such a mechanism which can increase the vehicle stability and passenger comfort. The main objective is to provide banking to the car on unbanked curves to run at high speed. The central front suspension has been used to provide vehicle stability. The design has been made and fabricated to minimize rolling tendency of the narrow track cars by introducing the auto-tilting mechanism. It improves the handling of the vehicle and hence provides more comfort to the passengers by minimizing rolling tendency and providing banking to the car. Keywords-narrow track car; rolling tendency; vehicle stability; banking to the car;auto-tilting mechanism
Critical thinking and cognitive biases

We argue that psychological research can enhance the identification of reasoning errors and the development of an appropriate pedagogy to instruct people in how to avoid these errors. In this paper we identify some of the findings of psychologists that help explain some common fallacies, give examples of fallacies identified in the research that have not been typically identified in philosophy, and explore ways in which this research can enhance critical thinking instruction.
Alternative Medicine: Stress Management and Opioids Use

The purpose of this paper is to provide literature review of studies that focused on stress and opioids use. The subjective nature of stress makes any given individual respond to any potential stressor in a unique individualized manner, based on the psychological, physical, and previous life experiences that build up the ability of the individual to adapt to stressors. Stress is defined as a “Perceptual phenomena arising from a comparison between the demand on the person and his ability to cope, an imbalance in this mechanism gives rise to the experience of stress” [1]. Stress can increase vulnerability to addiction. Research studies have defined the important role of endogenous opioids in modulating stressassociated behavior. Administration of mu opioid agonists reduces the risk of developing post-traumatic stress disorder (PTSD) following a traumatic event by inhibiting fear-related memory consolidation, on the other hand, stress induces opioid craving and reinstates drug of abuse [2].
Isolation and characterization of pyrimidine-psoralen-pyrimidine photodiadducts from DNA. [Ultraviolet radiation]

The isolation and characterization of pyrimidine-psoralen-pyrimidine photodiadducts from DNA are reported for the first time. For each of the four psoralens studied, a single pair of diastereomeric thymidine-psoralen-thymidine photodiadducts, each with cis-syn stereochemistry, was found to account for > 90% of the diadducts formed. Additionally, pulse-chase experiments that establish that these photo cross-links are formed by cycloaddition of a second thymidine residue to the 3,4 double bond (pyrone side) of an initially formed 4',5' (furan-side) psoralen-thymidine photomonoadduct have been carried out.
The investigation of substrate's dielectric properties for improving the performance of witricity devices

In designing a better Witricy device, there are several parameters that contribute to the improvement of efficiency. In this article, the substrate characteristics, which gaining less attention despite their potential for the improvement of Witricity performance are thoroughly studied. The characteristics such permittivity and loss tangent that very common in microwave design are investigated. The investigation has proven that RO 3010 substrate composed of ceramic-filled Polytetrafluoroethylene (PTFE) composites is the best material for the optimal Witricity performance, independent of the spiral coil's number of turns. This is due to its high-energy storage capacity obtained from the real permittivity, and roughly low loss factor and tangent loss. Hence, the Rogers RO 3010 substrate is proposed in this study as it performs reliable 50% to 74% coupling efficiency with the varied number of spiral coil turns.
The Effects of MsrA and MsrB in Anoxia Tolerance in Aging Drosophila melanogaster

Anoxia occurs when cells are deprived of oxygen. Throughout the animal kingdom, organisms respond differently to anoxia. Drosophila melanogaster (fruit fly) enters a protective coma that allows it to withstand hours of anoxia. The greatest oxidative stress occurs during the period called reoxygenation. A burst of reactive oxygen species (ROS) is produced when oxygen is reintroduced to the cells. In humans, ROS cause oxidative damage to critical cellular molecules, which contributes to aging and development of age-related neurodegenerative diseases. Methionine, a common amino acid in proteins, is especially sensitive to oxidation by ROS. Two methionine sulfoxide reductases (MsrA and MsrB) effectively reduce the methionine sulfoxide residues back to functional methionine. Our lab is investigating a link between the Msr genes and anoxia recovery using Drosophila. Currently, little is known about how the absence of Msr activity affects the ability of Drosophila to recover from anoxia. In this study, MsrA and MsrB, single deletion mutants, were exposed to one hour of anoxia and the Drosophila Activity Monitor (DAM) recorded their recovery times. RNA interference (RNAi) lines were used to mimic the effect of these deletion lines by ubiquitously knocking down Msr expression. My current data indicates that there was a significant difference in recovery time for the MsrA and MsrB single loss-of-function genetic mutants during middle age, but not near senescence. Insight into the role(s) of Msr genes under anoxic stress could lead to a better understanding of how these genes contribute to aging.
