Validation of Serious Games Attributes Using the Technology Acceptance Model (2010)

The paper introduces a conceptual model for the design of serious games and uses the Technology Acceptance Model (TAM) for its validation. A specially developed game introduced international students to public transport in Southampton. After completing the game, participants completed a short questionnaire and the data was analyzed using structural equation modeling (SEM). The results identified the attributes and combinations of attributes that led the learner to accept and to use the serious game for learning. These findings are relevant in helping game designers and educational practitioners design serious games for effective learning.
On demand platform for online games (2006)

A shared infrastructure, based on emerging on demand computing models, that supports multiple games offers an attractive option for large-scale multiplayer online game providers who want to avoid the risk of investing in dedicated resources. In this paper, we describe a prototype implementation of a service platform for online games. The platform design follows the on demand computing paradigm. It offers integration using open standards and off-the-shelf software and embraces virtualization and simplification to enable sharing resources across games. We describe our experience with identifying appropriate performance metrics for provisioning game servers and with implementing reusable platform components that provide useful functionality for a variety of games.
Integrity verification method of Thai content for faxed document (2012)

Problem of altering content of faxed document extends in wider range including in Thailand. Since most companies/organizations in Thailand use only one fax machine for common use in each department to reduce the telephone payment and complexity of fax management, someone with malicious intention may get a faxed document directly and personally from fax machine, and then alter the content inside for his/her benefits. In this paper, such problem is addressed, and an integrity verification method of Thai content for faxed document based on MAC algorithm is proposed to detect changes in its content. Our proposed method can be applied to both traditional machine based faxing and Internet fax & fax software. The experimental results show the efficiency of the proposed method with different font sizes.
Fuzzy Evaluation Algorithm of Distribution Transformer Based on Adaptive Variable Weight (2017)

Considering status indicators degradation degree, a distribution transformer evaluation algorithm using adaptive variable weight is proposed based on fuzzy assessment. By analyzing the correlation of each single condition variable and the condition of transformer, condition variables are divided into important indexes and referential indexes. In terms of different condition variables, adaptive variable weight algorithm using suitable balance functions is built to calculate the weight coefficient separately. Combining existing fuzzy assessment procedures, an accurate transformer condition evaluation system is established using the variable weights obtained in this paper. The results of example showed that the proposed method can evaluate the condition of distribution transformer when referential index deviates from the normal state accurately.
Continuum Traffic Simulation (2010)

Abstract We present a novel method for the synthesis and animation of realistic traffic flows on large‐scale road networks. Our technique is based on a continuum model of traffic flow we extend to correctly handle lane changes and merges, as well as traffic behaviors due to changes in speed limit. We demonstrate how our method can be applied to the animation of many vehicles in a large‐scale traffic network at interactive rates and show that our method can simulate believable traffic flows on publicly‐available, real‐world road data. We furthermore demonstrate the scalability of this technique on many‐core systems.
Introduction (2010)

Easter 1992. A long line of people stretches across Red Square waiting their turn to visit the Lenin Mausoleum. Behind them the red bricks of the Historical Museum to which is attached a huge poster. As had been the case for many years the image is trinitarian, but in place of Marx, Engels and Lenin, are to be found Father, Son and Holy Ghost.
Online Monitoring Of Tool Wear In Drilling and Milling By Multi-Sensor Neural Network Fusion (2007)

In manufacturing systems the detection of tool wear during cutting process is one of the most important considerations. In order to perform online tool condition monitoring (TCM) for different cutting conditions, a sensor-integration strategy with machining parameters is proposed. TCM systems are most frequently based on the research which attempts to correlate the condition of drilling and milling tools to the signals obtained from multiple sensors (namely, cutting forces, vibration, current and sound connected to a CNC machine). The aim of the proposed study is to create a TCM system that will lead to a more efficient and economical machining tool usage. The used system is capable of accurate tool wear monitoring in around 97% accuracy. Experimental results under different conditions have demonstrated that TCM can be implemented by using neural network.
Effect of interfacial defects on the electronic properties of graphene/g-GaN heterostructures (2019)

To gain deep insights into their interactions, the effects of interfacial defects on the structural and electronic properties of graphene/g-GaN heterostructures were investigated by using first-principles calculations. The graphene/g-GaN-V<sub>Ga</sub> heterostructure maintains a p-type Schottky contact in the spin-up channel and the Schottky barrier height (SBH) is decreased to 0.332 eV, but there is not a metal/semiconductor contact in the spin-down channel. However, the n-type SBH is negative for the graphene/g-GaN-V<sub>N</sub> heterostructure, indicating an ohmic contact. Furthermore, the SBH in the graphene/g-GaN heterostructure can be effectively modulated by the interlayer distance. The research could provide a strategy for the development and fabrication of efficient novel nanoelectronic devices.
Japan, quo vadis? Strategic change in Japanese firms (1999)

Many Japanese firms have not adjusted to the aftermath of the bubble economy. The article explores reasons, arguing that many major Japanese firms followed an incremental strategy, whereas they now find themselves at the edge of chaos. A complete change of attitude is needed by the leaders of many companies. Suggestions are made for what is needed to take businesses into the 21st century. Copyright © 1999 John Wiley & Sons, Ltd.
At Light Speed: Advances in Optogenetic Systems for Regulating Cell Signaling and Behavior (2017)

Cells are bombarded by extrinsic signals that dynamically change in time and space. Such dynamic variations can exert profound effects on behaviors, including cellular signaling, organismal development, stem cell differentiation, normal tissue function, and disease processes such as cancer. Although classical genetic tools are well suited to introduce binary perturbations, new approaches have been necessary to investigate how dynamic signal variation may regulate cell behavior. This fundamental question is increasingly being addressed with optogenetics, a field focused on engineering and harnessing light-sensitive proteins to interface with cellular signaling pathways. Channelrhodopsins initially defined optogenetics; however, through recent use of light-responsive proteins with myriad spectral and functional properties, practical applications of optogenetics currently encompass cell signaling, subcellular localization, and gene regulation. Now, important questions regarding signal integration within branch points of signaling networks, asymmetric cell responses to spatially restricted signals, and effects of signal dosage versus duration can be addressed. This review summarizes emerging technologies and applications within the expanding field of optogenetics.

Efficient Photochemical Water Splitting by a Chemically Modified n-TiO <sub>2</sub> (2002)

Although n-type titanium dioxide (TiO2) is a promising substrate for photogeneration of hydrogen from water, most attempts at doping this material so that it absorbs light in the visible region of the solar spectrum have met with limited success. We synthesized a chemically modified n-type TiO2 by controlled combustion of Ti metal in a natural gas flame. This material, in which carbon substitutes for some of the lattice oxygen atoms, absorbs light at wavelengths below 535 nanometers and has a lower band-gap energy than rutile (2.32 versus 3.00 electron volts). At an applied potential of 0.3 volt, chemically modified n-type TiO2 performs water splitting with a total conversion efficiency of 11% and a maximum photoconversion efficiency of 8.35% when illuminated at 40 milliwatts per square centimeter. The latter value compares favorably with a maximum photoconversion efficiency of 1% for n-type TiO2 biased at 0.6 volt.
Resonating Valence Bond Phase in the Triangular Lattice Quantum Dimer Model (2001)

We study the quantum dimer model on the triangular lattice, which is expected to describe the singlet dynamics of frustrated Heisenberg models in phases where valence bond configurations dominate their physics. We find, in contrast to the square lattice, that there is a truly short ranged resonating valence bond phase with no gapless excitations and with deconfined, gapped, spinons for a finite range of parameters. We also establish the presence of crystalline dimer phases.
Distinguished Historical Geography Lecture: Carceral Space and the Usable Past (2013)

I am among a second generation of American feminist historical geographers. My advisor Jeanne Kay Guelke was a pioneer in the field, offering in the 1980s and 1990s some of the most incisive critiques of the masculinism of American historical geography.1 I was lucky to become her student while she also served as chair of the Geography Department at the University of Nebraska-Lincoln in the early 1990s; I think she was probably one of the first women to serve as such in the country. There are not many of us who would—then or now—self-identify as “feminist historical geographers,” though of course our work overlaps with that of scholars in many closely aligned fields such as critical historical geography, postcolonial studies, and feminist history and historiography. Nonetheless, it is important to pause and consider what the early feminist historical geographers and historians accomplished for us and for geography. Thanks to predecessors such as Jeanne, we can now take for granted altered notions about what events, places, processes, and especially people count in and for historical geography. They demanded new ways of thinking about traditional areas of historical geography research (e.g. settlement patterns, staple export production, and types of survey systems), and offered whole new scales and categories of study such as the home, domestic space, and social reproduction to do so. Of course what’s “in” and what’s “out” is always in flux. Thus one of the few areas where feminist historical geography aligned with critical race studies, for instance, was in colonial and postcolonial geographies.2 These, however, are now susceptible to drifting into the background, and places of colonial contact with them. We do not want to lose that foothold, though, and one way to keep race relations deeply in the mix is through historical carceral geographies, the subject of this paper. I recently became interested in critical prison studies as an activist—as a volunteer and now decade-long executive board member of a local nonprofit prisoner rights group called the Lewisburg Prison Project or LPP. The project’s focus is on conditions of confinement; that is, helping to protect the civil and human rights of inmates incarcerated in the 50+ prisons located in the Pennsylvania Middle (judicial) District. Where I live in Pennsylvania unfortunately has one of the highest concentrations of correctional facilities anywhere in the United States. Prisons are the second largest industry in Pennsylvania overall, and the state’s incarceration rate continues to outpace all the other US states.3 Recently, inspired by my association with LLP, my work has become more scholarly-activist in nature. I am presently working on a number of projects related to historical geographies of mass incarceration in the US and the “spatial violence” of late modern
AeGAN: Time-Frequency Speech Denoising via Generative Adversarial Networks (2020)

Automatic speech recognition (ASR) systems are of vital importance nowadays in commonplace tasks such as speech-to-text processing and language translation. This created the need for an ASR system that can operate in realistic crowded environments. Thus, speech enhancement is a valuable building block in ASR systems and other applications such as hearing aids, smartphones and teleconferencing systems. In this paper, a generative adversarial network (GAN) based framework is investigated for the task of speech enhancement, more specifically speech denoising of audio tracks. A new architecture based on CasNet generator and an additional feature-based loss are incorporated to get realistically denoised speech phonetics. Finally, the proposed framework is shown to outperform other learning and traditional model-based speech enhancement approaches.
Interrelations Between Socio-economic Development and Environmental Quality. a Simulation Integrating System Dynamics Models with GIS (2005)

System dynamics (SD) theory has long been deployed in modeling complex non-linear interrelationships but, so far it has not been common to do the kind of modeling in support of bringing environmental sustainability policies to practice. This is largely because the challenge of including spatial data has not yet been well met. Potential for adoption of SD and GIS methods in combination is exemplified with the results of a decision-support exercise designed for simulation and prediction of the dynamic inter-relationships between socio-economic development and environmental quality for the Wen, Pi, Du county in Sichuan province,southwestern China.
ϕX174 <i>cistron A</i> protein is a multifunctional enzyme in DNA replication (1977)

The cistron A protein induced by phage varphiX174 nicks (produces a single-strand break in) the viral strand of the superhelical varphiX duplex DNA, thereby forming a complex with the DNA. The protein, seen bound to the DNA in the electron microscope, was located in the restriction endonuclease fragment between nucleotides 4290 and 4330 on the varphiX map [Sanger, F., Air, G. M., Barrel, B. G., Brown, N. L., Coulson, A. R., Fiddes, J. C., Hutchison, C. A., III, Slocomb, P. M. Y. & Smith, M. (1977) Nature 265, 687-695]. Replication also was initiated at this point, thus identifying the site of cistron A protein nicking and binding as the origin of replication. The cisA-DNA complex (separated from free cistron A protein), upon the addition of Escherichia coli rep protein, ATP, and DNA binding protein, is unwound to generate a single-stranded linear [presumably the nicked (+) strand] and a circular [presumably the (-) strand] molecule. The cisA-DNA complex, upon the further addition of DNA polymerase III holoenzyme and deoxynucleoside triphosphates, supports replication to generate viral, single-stranded circles, as many as 15 circles per cisA-DNA complex. The replicating intermediates seen in the electron microscope are a novel form of "rolling circle" [Gilbert, W. & Dressler, D. H. (1969) Cold Spring Harbor Symp. Quant. Biol. 33, 473-485]. The 5' end (presumably with the cistron A protein bound to it) is locked in the replication fork and loops back to accompany the strand-separation and replication fork around the template [(-) strand] circle. Thus, the multiple functions of cistron A protein include: (i) nicking the viral strand at the origin of replication to initiate a round of replication, (ii) participating in a complex which supports fork movement in strand separation and replication, (iii) nicking again at the regenerated origin to produce a unit-length DNA, and (iv) ligating the newly generated 3'-OH end to the 5'-phosphate-complexed end to form a circular viral molecule.

ThriftStore: Finessing Reliability Trade-Offs in Replicated Storage Systems (2010)

This paper explores the feasibility of a storage architecture that offers the reliability and access performance characteristics of a high-end system, yet is cost-efficient. We propose ThriftStore, a storage architecture that integrates two types of components: volatile, aggregated storage and dedicated, yet low-bandwidth durable storage. On the one hand, the durable storage forms a back end that enables the system to restore the data the volatile nodes may lose. On the other hand, the volatile nodes provide a high-throughput front-end. Although integrating these components has the potential to offer a unique combination of high throughput and durability at a low cost, a number of concerns need to be addressed to architect and correctly provision the system. To this end, we develop analytical and simulation-based tools to evaluate the impact of system characteristics (e.g., bandwidth limitations on the durable and the volatile nodes) and design choices (e.g., the replica placement scheme) on data availability and the associated system costs (e.g., maintenance traffic). Moreover, to demonstrate the high-throughput properties of the proposed architecture, we prototype a GridFTP server based on ThriftStore. Our evaluation demonstrates an impressive, up to 800 Mbps transfer throughput for the new GridFTP service.
The pig as a model in liver xenotransplantation. (1997)

Xenotransplantation is considered to be the best solution to the critical shortage of human donors. Despite its phylogenetic distance, the pig appears to be the most appropriate source of organs for transplantation in humans. Its anatomy and physiology are similar to that of man, it can be raised in specific pathogen free environments and it is available in large quantities. The immunological barrier remains to be overcome, however. Considerable progress in the pathogeny of xenogenic rejection has led to the development of therapeutic strategies and the prospect of clinical xenografting appears realisable in the near future.
Core Fucosylation of IgG B Cell Receptor Is Required for Antigen Recognition and Antibody Production (2015)

Ag recognition and Ab production in B cells are major components of the humoral immune response. In the current study, we found that the core fucosylation catalyzed by α1,6-fucosyltransferase (Fut8) was required for the Ag recognition of BCR and the subsequent signal transduction. Moreover, compared with the 3-83 B cells, the coalescing of lipid rafts and Ag-BCR endocytosis were substantially reduced in Fut8-knockdown (3-83-KD) cells with p31 stimulation and then completely restored by reintroduction of the Fut8 gene to the 3-83-KD cells. Indeed, Fut8-null (Fut8(-/-)) mice evoked a low immune response following OVA immunization. Also, the frequency of IgG-producing cells was significantly reduced in the Fut8(-/-) spleen following OVA immunization. Our results clearly suggest an unexpected mode of BCR function, in which the core fucosylation of IgG-BCR mediates Ag recognition and, concomitantly, cell signal transduction via BCR and Ab production.
REM Sleep Classification with Respiration Rates (2007)

Polysomnagraphy, the method evaluating the sleep quality, is the reliable and standard method. However, to perform it, subject has to attach many sensors to their body. It seems intrusive, tangled and interrupting the subjects sleep. For the sake of monitoring the daily sleep pattern, simple method measuring the biosignal nonintrusively is needed. At that point, respiration is a beneficial signal, because it can be easily acquired by check the change of the thorax or abdomen. Respiration is one of the representatives of the reflection of the autonomic nervous system. According to the transition of the sleep stages, autonomic nervous system also changes and it can be shown by respiration. In this study, REM and non-REM sleep is classified by only using respiration for the 3 subjects. To enhance the performance, activity signal acquired by load-cell installed bed is added to divide the wake and REM sleep. At the results, hypnograms with polysomnagraphic data is compared with them. It can be seen that high correlation between the REM sleep and increasing pattern of the respiration rates.
