The maximum field effect mobility measured in the saturation region was . A unity current gain cutoff frequency, , and maximum frequency of oscillation, of 180 and 155 MHz, respectively, were obtained. The equivalent device parameters were extracted by fitting the measured parameters to obtain the intrinsic transconductance, drain resistance, drain-source resistance, transit time, and gate-drain and gate-source capacitance.
Parallel community detection on large networks with propinquity dynamics (2009)

Graphs or networks can be used to model complex systems. Detecting community structures from large network data is a classic and challenging task. In this paper, we propose a novel community detection algorithm, which utilizes a dynamic process by contradicting the network topology and the topology-based propinquity, where the propinquity is a measure of the probability for a pair of nodes involved in a coherent community structure. Through several rounds of mutual reinforcement between topology and propinquity, the community structures are expected to naturally emerge. The overlapping vertices shared between communities can also be easily identified by an additional simple postprocessing. To achieve better efficiency, the propinquity is incrementally calculated. We implement the algorithm on a vertex-oriented bulk synchronous parallel(BSP) model so that the mining load can be distributed on thousands of machines. We obtained interesting experimental results on several real network data.
An Automatic Magnetic Balance for the Study of Ferromagnetic Materials (1951)

An instrument is described for plotting, automatically, magnetization-temperature curves for ferromagnetic substances. The sample is placed on a torsion arm in an inhomogenous magnetic field, and the force to which it is subjected is opposed by a torque applied to a torsion wire by a reversible motor. The shaft of the motor is connected to a Beckmann Helipot, and the motion of the shaft is converted into a change in emf. which is recorded by a Leeds and Northrup Speedomax. The temperature of the sample is also controlled and recorded by the Speedomax. Data on the performance of the instrument are given and sample plots of thermomagnetic runs for Ni, Fe3O4, and Fe3C are shown.
Electron Spin Resonance in Amorphous Silicon, Germanium, and Silicon Carbide (1969)

The $g$ values, line shapes, and linewidths of the ESR signals from within the bulk of amorphous silicon, germanium, and silicon carbide are found to be similar to those of the electron states observed in the surface regions of the corresponding crystalline forms. Discussion is given in terms of a microcrystalline model.
CATCHING UP ON COMPOSITES (1996)

Until recently, Japan and Germany were way ahead of the U.S. in composite material technology for construction. Lighter, stronger and possibly more durable than conventional materials like concrete, steel and timber, composites are finally seeping out of the lab and into the U.S. construction market. Trying to get your mind around the term composites is like a walk on the dunes--the ground is constantly shifting beneath your feet. Some people consider concrete a fine example of a composite material, while others hold up fiber reinforced plastic (FRP) or carbon fiber reinforced concrete (CFRC) as the materials that define composite. Regardless of how they split the semantic hair, many civil engineers are looking at composites as a viable building material for both new large scale projects and retrofits. And the research is finally being conducted to help them conceptualize applications and determine usages for these valuable and versatile materials.

Functional conjugated microporous polymers: from 1,3,5-benzene to 1,3,5-triazine (2012)

Conjugated microporous polymers (CMPs) based on the electron-withdrawing 1,3,5-triazine node (TCMPs) were synthesized by palladium-catalyzed Sonogashira-Hagihara cross-coupling. The porosity in these polymers was found to be comparable to the analogous 1,3,5-connected benzene CMP systems that we reported previously, demonstrating that nodes can be substituted in these amorphous materials in a rational manner, much as for certain crystalline porous metal–organic frameworks. The CO2 adsorption properties of the TCMPs were measured and compared with the corresponding CMPs, and it was found that the TCMP networks adsorbed more CO2 than CMP analogues with comparable BET surface areas. Network TNCMP-2 showed the highest surface area (995 m2 g−1) and a CO2 uptake of 1.45 mmol g−1 at 1 bar at 298 K. The band gap in these triazine-based CMPs could also be engineered through copolymerization with other functional monomers.
A substitution at a non-glycine position in the triple-helical domain of pro alpha 2(I) collagen chains present in an individual with a variant of the Marfan syndrome. (1990)

A substitution for a highly conserved non-glycine residue in the triple-helical domain of the pro alpha 2(I) collagen molecule was found in an individual with a variant of the Marfan syndrome. A single base change resulted in substitution of arginine618 by glutamine at the Y position of a Gly-X-Y repeat, and is responsible for the decreased migration in SDS-polyacrylamide gels of some pro alpha 2(I) chains of type I collagen synthesized by dermal fibroblasts from this individual. Family studies suggest that this substitution was inherited from the individual's father who also produces abnormally migrating pro alpha 2(I) collagen chains and shares some of the abnormal skeletal features. This single base change creates a new Bsu36 I (Sau I, Mst II) restriction site detectable in genomic DNA by Southern blot analysis when probed with a COL1A2 fragment. The analysis of 52 control individuals (103 chromosomes) was negative for the new Bsu36 I site, suggesting that the substitution is not a common polymorphism.
Fine structure in thermal growth patterns of bacteria by microcalorimetry (1973)

Thermal growth patterns of Enterobacter cloacae , Proteus rettgeri, and Klebsiella pneumoniae have been determined with the new NBS Clinical Microcalorimeter. These patterns show more fine structure than those made by previous calorimeters. This is due to the much faster time constant (half-time 30 seconds), the use of smaller volumes (0.4 ml) or thicknesses (2.5 mm) of samples, and the high sensitivity of the NBS Microcalorimeter.. Furthermore, this fine structure is shown to be reproducible and thus is valuable for finer bacterial "fingerprinting" or identification than was previously available. The simplicity of the apparatus and the ease of insertion of samples and operation of the calorimeter make this method attractive for possible routine use in detection and identification of bacteria.
Potential antitumor agents. 20. Structure-activity-site relations for the 4'-(9-acridinylamino)alkanesulfonanilides (1976)

A series of 87 L1210 active 4'-(9-acridinylamino)alkanesulfonanilides has been screened against L1210 cells (10(5)) implanted at various sites (ip, sc, ic) employing early ip drug administration for a limited time. With each implantation site a different most active congener was selected. For good activity against tumor implanted remotely from the ip drug administration site, an agent should be more lipophilic than that found optimal for ip implanted tumor. An acridine 4-CH3 group appears to assist drug translocation, possibly by sterically hindering binding to nonproductive sites. An unprotected NH2 group on the acridine ring system is incompatible with activity against sc implanted tumor. Agents in which NH2 is shielded by N-acetylation, N-monomethylation, or ortho substitution with a bulky group can inhibit sc implanted tumor.

Levosimendan in Acute and Advanced Heart Failure: An Appraisal of the Clinical Database and Evaluation of Its Therapeutic Applications (2017)

The use of inotropes for correcting hemodynamic dysfunction in patients with congestive heart failure has been described over many decades. However, negative or insufficient data have been collected regarding the effects of cardiac glycosides, catecholamines, and phosphodiesterase inhibitors on quality of life and survival. More recently, the calcium sensitizer and potassium channel-opener levosimendan has been proposed as a safer inodilator than traditional agents in some heart failure settings, such as advanced heart failure. At the 2017 annual congress of the Heart Failure Association of the European Society of Cardiology (Paris, April 30-May 2), a series of tutorials delivered by lecturers from 8 European countries examined how to use levosimendan safely and effectively in acute and advanced heart failure. The proceedings of those tutorials have been collated in this review to provide an expert perspective on the optimized use of levosimendan in those settings.
Development of Loan Module using Business Rules Engine (2014)

Banking loan module is a runtime business application. It is the automatic processing of all the loans, due to which the loan form can be filled from anywhere and the bank person approves loan within short span of time. There is very big crowd to fill the loan form manually which is very tiresome job. Also the manual process is very lengthy process which requires 3 days for approval of loan. Our customers will having their loan applications approved within 60 minutes of lodging the application instead of 3 days as per the paper-centric solution we were persisting with. This paper consists of method of development of dynamic loan module system which includes the loan origination process, loan form filling process and loan verification process. The method is developed by using the RETE pattern matching algorithm. Due to which the loan module system becomes very fast and work effective. In addition to this loan module system, we have also developed the CIBIL score generating system for the approved loan applications and determination of rupee dollar rate and calculation of rate of interest of loans. Due to which the manager originates the roi of loans that also helps the manager to stabilize the India’s economy and prevents itself from recession and other economic falls.
Fiber-loop ring-down spectroscopy (2002)

Pulsed, visible and near-infrared laser light is coupled into an optical fiber, which is wound into a loop using a fiber splice connector. The light pulses traveling through the fiber-loop are detected using a photomultiplier detector. It is found that once the light is coupled into the fiber it experiences very little loss and the light pulses do a large number of round trips before their intensity is below the detection threshold. Measurements of the loss-per-pass and of the ring-down time allow for characterization of the different loss mechanisms of the light pulses in the fiber and splice connector. This method resembles “cavity ring-down absorption spectroscopy” and is well suited to characterize low-loss processes in fiber optic transmission independent from power fluctuations of the light source. It is demonstrated that by measuring the ring-down times one can accurately determine the absolute transmission of an optical fiber and of the fiber connector. In addition it is demonstrated that the technique is useful as an absorption spectroscopic technique of very small sample volumes. A solution of an organic dye was placed between the fiber ends instead of the usual index matching fluid, and an absorption spectrum of 7×10−15 mol of the dye 1,1′-diethyl-4,4′-dicarbocyanine iodide in 7×10−12 L of dimethylsulfoxide was recorded.
Experimental analysis of waveform effects on satellite and ligament behavior via<i>in situ</i>measurement of the drop-on-demand drop formation curve and the instantaneous jetting speed curve (2010)

In situ techniques to measure the drop-on-demand (DOD) drop formation curve and the instantaneous jetting speed curve are developed such that ligament behavior and satellite behavior of inkjet droplets can be analyzed effectively. It is known that the droplet jetting behavior differs by ink properties and the driving waveform voltage. In this study, to reduce possible droplet placement errors due to satellite drops or long ligaments during printing, waveform effects on drop formation are investigated based on the measured DOD drop formation curve and the instantaneous jetting speed curve. Experimental results show that a dwell time greater than the so-called efficient dwell time was effective in reducing placement errors due to satellite drops during the printing process.
Alumite disc using anodic oxidation. (1987)

Details are given of a method of measuring perpendicular magnetic alumite discs using anodization with an additional new process called “pore widening” which is effective in controlling the coercive force. Electro-deposited fine iron needles were in a single crystalline state, and the perpendicular orientation of magnetization was confirmed. The resulting magnetic recording characteristics of the rigid discs were satisfactory, indicating usefulness of the method as a perpendicular recording medium.
Tissue-specific expression and developmental regulation of the rat apolipoprotein B gene. (1986)

Expression of the apolipoprotein B (apoB) gene was examined in a variety of fetal, neonatal, and adult rat tissues by probing RNA blots with a cloned rat apoB cDNA. Among 10 adult male tissues surveyed, small intestine had the highest concentration of apoB mRNA. Its abundance in liver and adrenal gland was 40% and 0.5%, respectively, of that in small bowel, while none was detected in colon, kidney, testes, spleen, lung, heart, or brain. ApoB mRNA is as abundant in 18-day fetal liver as at any subsequent period of hepatic development. In contrast, the concentration of apoB mRNA remains low in fetal intestine until the last (21st) day of gestation, when it increases sharply to levels that are several-fold higher than in the liver. ApoB mRNA levels in fetal membranes harvested during this late gestational period were 10 times greater than in fetal liver. Since the major lipoprotein species in 19-day fetal plasma is low density lipoprotein, these observations suggest that fetal liver, and particularly its functional homologue, the yolk sac, are the principal sites of fetal lipoprotein synthesis at this stage of development. A 20-fold increase in placental apoB mRNA concentrations during the last 48 hr of pregnancy (to a level that is 50% of that encountered in fetal membrane RNA) suggests a specific role for this organ in maternal-fetal lipid transport immediately prior to parturition. Pulse-labeling experiments using 21-day fetal tissue slices showed that the liver synthesizes both apoB-100 (B-PI) and apoB-48 (B-PIII) albeit in somewhat different ratios than the adult organ. Fetal intestine produces almost exclusively the smaller apoB species, while fetal membranes and placenta synthesize only the larger peptide. The postnatal pattern of apoB mRNA accumulation is similar in liver and intestine. Profound decreases were observed during the late suckling and weaning periods, followed by an increase to adult levels. These final concentrations were similar to those encountered at birth. Analysis of these developmental changes offers an opportunity to generate testable hypotheses about the factors that modulate apoB synthesis.
VisMOOC: Visualizing video clickstream data from Massive Open Online Courses (2015)

Massive Open Online Courses (MOOCs) platforms are becoming increasingly popular in recent years. With thousands of students watching course videos, enormous amounts of clickstream data are produced and recorded by the MOOCs platforms for each course. Such large-scale data provide a great opportunity for instructors and educational analysts to gain insight into online learning behaviors on an unprecedented scale. Nevertheless, the growing scale and unique characteristics of the data also pose a special challenge for effective data analysis. In this paper, we introduce VisMOOC, a visual analytic system to help analyze user learning behaviors by using video clickstream data from MOOC platforms. We work closely with the instructors of two Coursera courses to understand the data and collect task analysis requirements. A complete user-centered design process is further employed to design and develop VisMOOC. It includes three main linked views: the List View to show an overview of the clickstream differences among course videos, the Content-based View to show temporal variations in the total number of each type of click action along the video timeline, the Dashboard View to show various statistical information such as demographic information and temporal information. We conduct two case studies with the instructors to demonstrate the usefulness of VisMOOC and discuss new findings on learning behaviors.
Human action recognition using fusion of modern deep convolutional and recurrent neural networks (2018)

This paper studies the application of modern deep convolutional and recurrent neural networks to video classification, specifically human action recognition. Multi-stream architecture, which uses the ideas of representation learning to extract embeddings of multimodal features, is proposed. It is based on 2D convolutional and recurrent neural networks, and the fusion model receives a video embedding as input. Thus, the classification is performed based on this compact representation of spatial, temporal and audio information. The proposed architecture achieves 93.1% accuracy on UCF101, which is better than the results obtained with the models that have a similar architecture, and also produces representations which can be used by other models as features; anomaly detection using autoencoders is proposed as an example of this.
Novel poly(pyridine imide) with pendent naphthalene groups: Synthesis and thermal, optical, electrochemical, electrochromic, and protonation characterization (2007)

Abstract A new diamine containing a pyridine heterocyclic group and a naphthalene substituent, 4‐(2‐naphthyl)‐2,6‐bis(4‐aminophenyl) pyridine (NBAPP), was synthesized with the Chichibabin reaction and used in the preparation of poly(pyridine imide) by direct polycondensation with 4,4′‐hexafluoroisopropylidenediphathalic anhydride in N ‐methyl‐2‐pyrrolidinone (NMP). The poly(pyridine imide) derived from diamine NBAPP with naphthalene substituents was highly organosoluble: it was soluble in tetrahydrofuran, NMP, N,N ‐dimethylacetamide (DMAc), N,N ‐dimethylformamide, and γ‐butyrolactone at room temperature and in pyridine, dimethyl sulfoxide, and cyclohexanone upon heating at 70 °C. The poly(pyridine imide) was converted into lightly colored, optically transparent, flexible, and tough polyimide films via casting onto glass from a DMAc solution. This polymer exhibited good thermal stability (temperature of 10% weight loss = 527 °C) in air and high dielectric constants (as high as 4.20 at 1 kHz). The polyimide films had a tensile strength of 102 MPa and a tensile modulus of 1.8 GPa. As for the optical properties, the polymer exhibited UV–vis absorption bands in the region of 223–450 nm and possessed strong green‐yellow fluorescence (500 nm) after being protonated with acid. © 2007 Wiley Periodicals, Inc.

A subset of the ISDN network layer protocol suitable for implementation in hardware (2003)

A discussion is presented of the selection of a subset of the ISDN (integrated-services digital network) signalling system's network-layer protocol for point-to-point links suitable for processing in VLSI. A symmetric subset of the CCITT Q.931 recommendation as it stood in August 1987 is proposed. The need for bearer-channel negotiations is eliminated by using a 'two-way independent channel selection' technique in which each end of the link is master in the transmit direction and slave in the receive direction. A logical model for the signalling system's network layer processor is developed to aid in understanding the Q.931 protocol. The model also serves as the initial functional partitioning for the VLSI implementation. The key element of the model is the separation of the network-layer processor into a protocol-specific module (PSM) and an application-specific module (ASM).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Study on examination center scheduling problem based on genetic algorithm and simulated annealing algorithm (2014)

A new hybrid flow shop scheduling problem is studied, which is abstracted from the physical examination centre. The problem is characterized by multi-stage unrelated parallel rooms and continuous examination. Firstly, the math model of this hybrid scheduling problem is constructed. And then the computation method of examination period is given. In order to keep examining continuously, the examination period is obtained through reversely pushing from the examination scheduling problem with multistage unrelated parallel rooms and examining interruption. Then the scheduling results are obtained based on genetic algorithm and simulated annealing algorithm(GASA). Function objective of the proposed method was to minimize the examination period. Finally scheduling results based on two cases show that the method proposed in this paper is effective and feasible.
