Frictional Behavior of Plain Woven Fabrics Constructed from Polyester and Cotton Yarns in Different Environmental Conditions (2012)

Frictional characteristics of woven fabrics can determine smoothness and softness values of the fabric. Moreover different environmental conditions can leads to change the properties of the weaves. In this paper, we studied the effect of temperature and relative humidity variations on the frictional properties of cotton and polyester fabrics. Plain woven fabrics were produced with polyester warp yarn and two different weft yarns (cotton and polyester). Each fabric was examined in various temperatures and relative humilities; then the frictional forces measurement was carried out on the fabrics in warp over warp direction. The results show that there is a statistically significant difference between the frictional parameters. This difference relates to the type of fiber material (weft yarns), temperature, and relative humidity. In addition, the data reveal that cotton fabrics have more static and kinetic forces than polyester fabrics in all environmental conditions. Moreover, polyester fabrics exposed to a temperature of nearly 45°C and 100% RH, have the maximum smoothness. The highest roughness values for cotton fabrics were under conditions of 45°C and 20% RH.
Relaxed silicon–germanium-on-insulator fabricated by oxygen implantation and oxidation-enhanced annealing (2005)

The application of separation-by-implantation-of-oxygen (SIMOX) for silicon–germanium-on-insulator (SGOI) fabrication is always limited by the Ge loss caused by the high temperature annealing. A unique SIMOX method was introduced to fabricate SGOI and resolve the problem of Ge loss. During the process, a SiO2 layer was formed pre-annealing to block the Ge out-diffusion. As the x-ray rocking curve and Raman spectra studies show, the Ge fraction of the SGOI was improved to 17 at.%. The final sample exhibits a planar and continuous buried oxide layer, sharp interfaces and a defect free top SiGe layer as the cross-sectional transmission-electron- microscopy (XTEM) and secondary-ion-mass-spectrometry studies show. The Rutherford backscattering spectroscopy demonstrated that the superficial SiGe layer was superior in quality (derived channelling yield of 10%). The results indicate that the additional step of thermal oxidation pre-annealing is vital to resolve the problem of Ge loss and the modified SIMOX process is applicable for SGOI fabrication.
Clinical and Experimental Histological Studies on Effects of Salicylate and Quinine on the Ear (1942)

The war apparently has not been able, even in Europe, to smother entirely the type of detailed clinical study represented by this monograph, which evidences a great deal of work and is in the true continental style with full preliminary remarks on the pharmacology of the drugs investigated, namely salicylic acid and quinine; and it includes an extensive critical survey of all available pertinent preexisting contributions on the subject of the author's studies. He then relates the manner in which he tested hearing and labyrinthine functions in order to establish normal criteria. Under proper controls both tuning forks and the audiometer were used; healthy volunteers were examined after ingestion of sodium salicylate and quinine sulfate; patients with abnormal hearing were similarly tested and there were a number of instances in which individuals with acute quinine poisoning and protracted salicylate ingestion were observed. There were, in addition, controlled animal experiments with
Integrated vertical screen microfilter system using inclined SU-8 structures (2003)

A multidimensional, vertical screen filter system is developed in which structures analogous to the mesh of a window screen are extended vertically through the cross-sectional area of a simultaneously-formed flow channel. Vertical screens with heights of up to 400 microns and aperture sizes of 10 microns have been achieved in a simple, multiexposure fabrication approach without the need for stacking or lamination. A triple filtering system with multiple inlet and outlet streams and three different mesh sizes of 57.3 /spl mu/m, 27.3 /spl mu/m, and 10.0 /spl mu/m in its horizontal diagonal has been simultaneously fabricated with flow channels and tested. Each mesh filters out microparticles larger than 35 /spl mu/m, 18 /spl mu/m, and 6 /spl mu/m, accordingly. In addition to microfiltering, the utility of the vertical screen filter structure as a passive micromixer has been demonstrated.
Higher Alcohol Synthesis over Double Bed Cs−Cu/ZnO/Cr<sub>2</sub>O<sub>3</sub> Catalysts:  Optimizing the Yields of 2-Methyl-1-propanol (Isobutanol) (1998)

Higher alcohol synthesis from H2/CO has been carried out over two tandem beds of a cesium-promoted Cu/ZnO/Cr2O3 catalyst with a temperature difference between the beds. Lower alcohols produced in the low temperature top bed are supplied as oxygenated precursors to the higher temperature bottom bed to react further in the chain growth process leading to the formation of higher alcohols. In this configuration, a high space time yield of 202 g/kg of catalyst/h of 2-methyl-1-propanol (isobutanol) was obtained. This presently observed yield of isobutanol in a double bed configuration with the copper-based catalyst in both beds represents a very significant enhancement over the earlier reported isobutanol yields in a double bed confiuration with a copper-free catalyst in the second bed (Beretta et al., 1996). A kinetic reaction network (Smith et al., 1991) was modified to model this double bed catalyst configuration. This model was then used to obtain kinetic parameters and predict product yields for the reaction system in the current study. It was also demonstrated that the kinetic model could be used as a predictive tool to optimize experimental parameters. In particular, the model was used to predict the optimum mass ratio of the two catalyst beds to produce the maximum yield of isobutanol.
Synthesizing human motion in a CG authoring environment for nonprofessionals (2002)

We describe the system we developed to make the authoring of 3D computer graphic animations easy for nonprofessionals. The system features several new elements such as the lip-synchronization system and motion edit software. Using the lip-synchronization system, we can easily synchronize the motion of the mouth shape with voice data. We apply automatic segmentation of voice data to properly set keyframes. The motion edit software intelligently emphasizes the motion data, which is obtained from real motion by motion capturing, to make it fit to a particular animation character.
Designer diatom episomes delivered by bacterial conjugation (2015)

Eukaryotic microalgae hold great promise for the bioproduction of fuels and higher value chemicals. However, compared with model genetic organisms such as Escherichia coli and Saccharomyces cerevisiae, characterization of the complex biology and biochemistry of algae and strain improvement has been hampered by the inefficient genetic tools. To date, many algal species are transformable only via particle bombardment, and the introduced DNA is integrated randomly into the nuclear genome. Here we describe the first nuclear episomal vector for diatoms and a plasmid delivery method via conjugation from Escherichia coli to the diatoms Phaeodactylum tricornutum and Thalassiosira pseudonana. We identify a yeast-derived sequence that enables stable episome replication in these diatoms even in the absence of antibiotic selection and show that episomes are maintained as closed circles at copy number equivalent to native chromosomes. This highly efficient genetic system facilitates high-throughput functional characterization of algal genes and accelerates molecular phytoplankton research.
Radiofrequency ablation of arrhythmias guided by non-fluoroscopic catheter location: a prospective randomized trial (2006)

Ensite NavX and Carto procedures have similar effectiveness and safety to a conventional approach; however, they both reduce X-ray exposure, with NavX producing a significantly greater effect than Carto. Although this benefit is achieved at a greater financial cost, there may be long-term benefits to catheter laboratory staff.
Designing and Implementing the OP and OP2 Web Browsers (2011)

Current web browsers are plagued with vulnerabilities, providing hackers with easy access to computer systems via browser-based attacks. Browser security efforts that retrofit existing browsers have had limited success because the design of modern browsers is fundamentally flawed. To enable more secure web browsing, we design and implement a new browser, called the OP web browser, that attempts to improve the state-of-the-art in browser security. We combine operating system design principles with formal methods to design a more secure web browser by drawing on the expertise of both communities. Our design philosophy is to partition the browser into smaller subsystems and make all communication between subsystems simple and explicit. At the core of our design is a small browser kernel that manages the browser subsystems and interposes on all communications between them to enforce our new browser security features. To show the utility of our browser architecture, we design and implement three novel security features. First, we develop flexible security policies that allow us to include browser plugins within our security framework. Second, we use formal methods to prove useful security properties including user interface invariants and browser security policy. Third, we design and implement a browser-level information-flow tracking system to enable post-mortem analysis of browser-based attacks. In addition to presenting the OP browser architecture, we discuss the design and implementation of a second version of OP, OP2, that includes features from other secure web browser designs to improve on the overall security and performance of OP. To evaluate our design, we implemented OP2 and tested both performance, memory, and filesystem impact while browsing popular pages. We show that the additional security features in OP and OP2 introduce minimal overhead.
An Improved Role-Based Workflow Access Control Model (2008)

The Role-Based Access Control (RBAC) model is widely accepted as the model of access control of workflow management system (WFMS). However, the RBAC model exist a lot of limit when it describe the authorization constraint of access control. Especially , the RBAC model cannot express the transaction character and the phase authorization constraint when the role and the user perform the task. This paper proposed an improved role-Based access control model for WFMS. The new authorization concepts for WfMS are defined respectively. The access control rules of IRBAC model are build, which can express complex access control constraints for WfMS.

Generative Temporal Models with Spatial Memory for Partially Observed Environments (2018)

In model-based reinforcement learning, generative and temporal models of environments can be leveraged to boost agent performance, either by tuning the agent's representations during training or via use as part of an explicit planning mechanism. However, their application in practice has been limited to simplistic environments, due to the difficulty of training such models in larger, potentially partially-observed and 3D environments. In this work we introduce a novel action-conditioned generative model of such challenging environments. The model features a non-parametric spatial memory system in which we store learned, disentangled representations of the environment. Low-dimensional spatial updates are computed using a state-space model that makes use of knowledge on the prior dynamics of the moving agent, and high-dimensional visual observations are modelled with a Variational Auto-Encoder. The result is a scalable architecture capable of performing coherent predictions over hundreds of time steps across a range of partially observed 2D and 3D environments.

Geometrical optimization of a longitudinal resonant photoacoustic cell for sensitive and fast trace gas detection (1996)

We present a quantitative discussion of the acoustic transmission line theory pertaining to experimental results from a resonant photoacoustic cell excited in its first longitudinal mode. Window absorption is optimally suppressed by buffer volumes and tunable air columns. The acoustic behavior of an ultrasensitive one inch condenser microphone is quantitatively described. A small and sensitive photoacoustic cell has been developed for intracavity use in a CO2 waveguide laser permitting measurements of ethylene down to 6 pptv (long term stability 20 pptv) with a time response of 2 s at a trace gas flow of 6 1/h. To demonstrate the fast time response within a biological application the instant ethylene release of a single tomato is measured.
RUNX1 regulates phosphoinositide 3-kinase/AKT pathway: role in chemotherapy sensitivity in acute megakaryocytic leukemia (2009)

RUNX1 (AML1) encodes the core binding factor alpha subunit of a heterodimeric transcription factor complex which plays critical roles in normal hematopoiesis. Translocations or down-regulation of RUNX1 have been linked to favorable clinical outcomes in acute leukemias, suggesting that RUNX1 may also play critical roles in chemotherapy responses in acute leukemias; however, the molecular mechanisms remain unclear. The median level of RUNX1b transcripts in Down syndrome (DS) children with acute megakaryocytic leukemia (AMkL) were 4.4-fold (P < .001) lower than that in non-DS AMkL cases. Short hairpin RNA knockdown of RUNX1 in a non-DS AMkL cell line, Meg-01, resulted in significantly increased sensitivity to cytosine arabinoside, accompanied by significantly decreased expression of PIK3CD, which encodes the delta catalytic subunit of the survival kinase, phosphoinositide 3 (PI3)-kinase. Transcriptional regulation of PIK3CD by RUNX1 was further confirmed by chromatin immunoprecipitation and promoter reporter gene assays. Further, a PI3-kinase inhibitor, LY294002, and cytosine arabinoside synergized in antileukemia effects on Meg-01 and primary pediatric AMkL cells. Our results suggest that RUNX1 may play a critical role in chemotherapy response in AMkL by regulating the PI3-kinase/Akt pathway. Thus, the treatment of AMkL may be improved by integrating PI3-kinase or Akt inhibitors into the chemotherapy of this disease.
Example-Based Color Stylization of Images (2005)

We describe a new computational approach to stylize the colors of an image by using a reference image. During processing, we take the characteristics of human color perception into account to generate more appealing results. Our system starts by classifying each pixel value into one of the basic color categories, derived from our psychophysical experiments. The basic color categories are perceptual categories that are universal to everyone, regardless of nationality or cultural background. These categories are used to provide restrictions on color transformations to avoid generating unnatural results. Our system then renders a new image by transferring colors from a reference image to the input image, based on these categorizations. To avoid artifacts due to the explicit clustering, our system defines fuzzy categorization when pseudocontours appear in the resulting image. We present a variety of results and show that our method performs a large, yet natural, color transformation without any sense of incongruity and that the resulting images automatically capture the characteristics of the colors used in the reference image.
Button battery ingestion: a case report and review of the literature. (1987)

Disc batteries represent a distinct type of pediatric foreign body because of their potential for severe morbidity and mortality. We present the case of an 18-month-old boy who ingested a lithium battery and, despite a delay in diagnosis, had a favorable outcome. Button batteries are being used with increasing frequency in a variety of devices including hearing aids, watches and calculators. Most contain a heavy metal such as mercury, and an alkaline electrolyte. Esophageal impaction results in a corrosive esophagitis leading to perforation with the attendant sequelae. Injury may occur by four mechanisms: (1) electrolyte leakage from batteries; (2) alkali produced from external currents; (3) mercury toxicity, and (4) pressure necrosis. Early diagnosis and urgent removal are required for esophageal impaction. More distal sites can be managed conservatively with spontaneous passage occurring in the majority of cases. Prevention should be directed at placing the cells out of reach and child-proofing battery-powered appliances.

CMOS quaternary latch (1989)

A new CMOS current-mode quaternary threshold logic latch circuit is presented. This circuit accepts and requantises quaternary logical currents during a SETUP clock mode and latches the input value during the HOLD clock mode. Using logical current increments of 10μA, the quaternary latch has been simulated to have a worst-case, three logic level transition, total SETUP and HOLD time of about 40 ns, and single level transition total SETUP and HOLD time of about 10 ns.

Selective Hybrid RSS/AOA Approximate Maximum Likelihood Mobile intra cell Localization. (2013)

We present in this paper two selective combined schemes for mobile location. These schemes are based respectively on the Linear Least Squares (LLS) and the Approximate Maximum Likelihood (AML) approaches. The proposed positioning techniques apply to intra cell localization in which the serving base station (BS) Angle Of Arrival (AOA) and the best two Received Signal Strength (RSS) measurements taken at some reference points (with known positions) are combined for mobile user localization. Such nodes are either localized users or anchors. The proposed approach achieves better performance compared to the selective RSS LLS method. The use of only the two best RSS measures reduces the location bias effect induced by propagation. It also decreases the computational burden implied by multiple RSS combining. Simulation results show that, for certain scenarios, the proposed selective hybrid RSS/AOA LLS (respectively AML) with two nodes outperforms the selective RSS LLS with up to seven nodes (respectively to ten nodes)and achieves equivalent performances to AOA-based approaches.
Conversion From Intravenous to Oral Medications (2003)

Computer-generated reminders can produce a substantial reduction in excessive use of targeted intravenous medications. As online prescribing becomes more common, this approach can be used to reduce excess use of intravenous medications, with potential benefits in patient comfort, safety, and cost.
Water blown free rise polyurethane foams (1999)

Abstract A model is developed in this work for predicting the bubble size distribution in polyurethane foams generated by using water as a chemical blowing agent. The model combines equations of energy balance, kinetics of the reactions of isocyanate with water and polyol, and nucleation and growth of CO 2 bubbles. It is found that as the water content of the reaction mixture is increased, the mean bubble size decreases and the bubble size distribution become narrower. Exactly the opposite occurs in polyurethanes foamed with a physical blowing agent, e.g., DuPont Freons. This suggests that a combination of physical and chemical blowing agents can be employed to control bubble size distribution.
Measurement and prediction of the flow through an annular turbine cascade (1993)

An annular turbine cascade was designed and manufactured for laser Doppler velocimetry and probe measurements in a small-scale rig. The purpose of the experiment was to determine the limitations of these measurements in a confined annulus, and to compare the experimental results with numerical predictions. Downstream probe surveys were conducted at a Reynolds number of 500000. Total pressure and temperature measurements were taken upstream of the test section, and hub static pressure was measured downstream of the cascade. A two-dimensional laser anemometer was used to obtain preliminary velocity field measurements for code validation. The two main problem areas identified were the type of seeding material used and the configuration of the optical access window. Flowfield characteristics were predicted using a three-dimensional viscous code, which were then compared to experimental measurements. The comparison showed that the numerical simulator predicted well the general features of the flow field that were measured in the experiment. Recommendations are made which would improve the mapping of the velocity field for a more complete code validation. RVC3D, Numerical simulation, Turbine, LDV, Cascade
0.15 μm T-shaped gate fabrication for GaAs MODFET using phase shift lithography (1996)

A new fabrication process of GaAs MODFETs with 0.15 micron T-shaped gate has been developed by using phase shift lithography. Sub-quarter micron footprints of T-shaped gates are defined as line patterns by PEL (pattern-edge line) method using chemically stable positive photoresist. Parasitic capacitances such as C/sub gs/ and C/sub gd/ are also reduced by the air-gap incorporated in the present process. An implemented GaAs MODFET exhibited the NF of 0.36 dB and the gain of 11.5 dB at the frequency of 12 GHz.
