A robust capacitive angular position sensor (2002)

A noncontacting robust capacitive angular position sensor currently under development for industrial and automotive application is presented. The main advantages of this low-cost system are its simplicity, high accuracy (/spl plusmn/0,2/spl deg/) and resolution (/spl plusmn/0,04/spl deg/) over the range of up to 360/spl deg/, excessive temperature operating capability, insensitivity to dirt, moisture and dew on the sensor electrodes and fast measurement speed. The paper describes the working principle, derives the required relationships for computing the rotor position and discusses the sensor's properties in relation to those of established encoder principles. The sensitivity of the sensor to mechanical errors like radial and axial axis offset, tilted axis, and tilted electrodes is explained. Finally the sensor electronics and its realization is discussed and data obtained from prototype sensors is presented.

Observation of hot-carrier-induced nFET gate-oxide breakdown in dynamically stressed CMOS circuits (2003)

Subjecting a ring oscillator circuit with short-channel thin-oxide FETs to dynamic stress results in the majority of nFET and pFET drain-side gate-oxide breakdowns. The enhancement in the drain-side breakdowns, which are potentially the most detrimental to circuit operation, is shown to be induced in nFETs by channel hot carriers.
Radio-Frequency Magnetometry Using a Single Electron Spin (2013)

We experimentally demonstrate a simple and robust protocol for the detection of weak radio-frequency magnetic fields using a single electron spin in diamond. Our method relies on spin locking, where the Rabi frequency of the spin is adjusted to match the MHz signal frequency. In a proof-of-principle experiment we detect a 7.5 MHz magnetic probe field of ~40 nT amplitude with <10 kHz spectral resolution. Rotating-frame magnetometry may provide a direct and sensitive route to high-resolution spectroscopy of nanoscale nuclear spin signals.
Osmotic, biomass, and oxygen effects on the growth rate of <i>Fusarium oxysporum</i> using a dissolved‐oxygen‐controlled turbidostat (1989)

The system described is a modified Hospodka's turbidostat. This device helps to measure the maximum growth rate of fungi in steady-state aerobic conditions with defined and independent concentration of dissolved oxygen, biomass, and substrate even unlimited. The principle consists of a turbidostat controlled by the dissolved oxygen concentration. The inlet medium pump operates when the dissolved oxygen concentration falls below the set point value. This method allows us to study independently effects of different physical and chemical variables on the maximum specific growth rate of microorganisms. A fungus, Fusarium oxysporum 47 isolated from soil, does not show a depressive effect on growth when dissolved oxygen concentration decreases to 5% and osmotic potential to -25 bars. Increasing biomass concentration in the range 0.1-1.0 g/L appears to depress markedly the maximum growth rate.
Ote-OCR based text recognition and extraction from video frames (2014)

The goal of this paper is to provide a new method to detect and recognize the text from the video frames. The task performed is divided into three step approach that combines the text detection and text recognition from the video frame. The video frame creation involves in dividing the video into an individual frames. The individual frame is grabbed and passed to the rest two phases. The text detection is a two-step approach, which involves text localization phase and the text verification phase. The text recognition involves in text verification phase and the optical character recognition phase. The final outcome of this paper is the detection of the text from the video frames in a word file. Experimental results demonstrating the proposed approach was also included, which shows the accuracy level of Optical character recognition(OCR) in terms of text extraction.

A Novel Selective JAK2 Inhibitor Identified Using Pharmacological Interactions (2018)

The JAK2/STAT signaling pathway mediates cytokine receptor signals that are involved in cell growth, survival and homeostasis. JAK2 is a member of the Janus kinase (JAK) family and aberrant JAK2/STAT is involved with various diseases, making the pathway a therapeutic target. The similarity between the ATP binding site of protein kinases has made development of specific inhibitors difficult. Current JAK2 inhibitors are not selective and produce unwanted side effects. It is thought that increasing selectivity of kinase inhibitors may reduce the side effects seen with current treatment options. Thus, there is a great need for a selective JAK inhibitor. In this study, we identified a JAK2 specific inhibitor. We first identified key pharmacological interactions in the JAK2 binding site by analyzing known JAK2 inhibitors. Then, we performed structure-based virtual screening and filtered compounds based on their pharmacological interactions and identified compound NSC13626 as a potential JAK2 inhibitor. Results of enzymatic assays revealed that against a panel of kinases, compound NSC13626 is a JAK2 inhibitor and has high selectivity toward the JAK2 and JAK3 isozymes. Our cellular assays revealed that compound NSC13626 inhibits colorectal cancer cell (CRC) growth by downregulating phosphorylation of STAT3 and arresting the cell cycle in the S phase. Thus, we believe that compound NSC13626 has potential to be further optimized as a selective JAK2 drug.
COMBINED INVARIANTS TO LINEAR FILTERING AND ROTATION (1999)

A new class of moment-based features invariant to image rotation, translation, scaling, contrast changes and also to convolution with an unknown PSF are introduced in this paper. These features can be used for the recognition of objects captured by a nonideal imaging system of unknown position and blurring parameters.
Dysglycemia and Dyslipidemia Models in Nonhuman Primates: Part II. Model of Naturally Occurring or Experimental Obesity (2015)

Obesity is viewed as one of the most serious public health issues of this century, which is likely due to economic growth, urbanization, modernization, life-style change and decreased physical activity. In 2013, the American Medical Association classified obesity as a disease. Sustained excessive accumulation of body fat to the extent, such as overweight or obesity, can reduce life expectancy and increase health risks, particularly heart disease and type 2 diabetes. Cardiovascular, diabetes and other health problems of obesity have been studied for many decades. Inflammation, mitochondrial dysfunction, hyperinsulinemia, lipotoxicity, medical and others, such as genetic background and aging, may result in obesity. However, the underlying precise mechanisms have yet to be elucidated further. Various obesity animal models have been used and induced for obesity research and therapy. To better understand the pathophysiology of human obesity, corpulent nonhuman primates (NHPs) are useful models due to resembling humans, not only physiologically but in eating habits (bored-eat). NHP obesity models have been developed and used for delineating molecular and cellular mechanisms and for testing new novel therapies, which provides critical pre-clinic information for drug discovery. We recently published the data obtained from naturally occurring diabetes NHPs. This article summarizes the data collected from a large scale of naturally occurring and high calorie (fat) diet (HCD)-induced obesity monkeys housed in our facility. Manuscript for another NHP model, streptozocin-induced diabetes, developed in our facility will follow lately.

Comparative efficacy of transvenous cardioversion and pacing in patients with sustained ventricular tachycardia: a prospective, randomized, crossover study. (1985)

We performed a prospective, randomized crossover study to evaluate the comparative efficacy of transvenous cardioversion and rapid ventricular pacing for termination of induced ventricular tachycardia in patients with spontaneous ventricular tachycardia and organic heart disease. Sixty-two episodes of ventricular tachycardia were induced in 15 patients, mean age 60 +/- 10 years, during electrophysiologic studies. All patients underwent a preselected electrical therapy protocol in a randomized crossover sequence. Transvenous cardioversion was performed by an incremental protocol of three sequential shocks (0.5, 1.1, and 2.7 J). Six asynchronous sequential bursts of rapid ventricular pacing (10 and 15 paced stimuli at 90%, 75%, and 65% of ventricular tachycardia cycle length) were used. Mean cycle length of ventricular tachycardia for the study population was 391 +/- 85 msec. The morphology of the tachycardia was left bundle branch block in 27, right bundle branch block in 32, and indeterminate in three. Characteristics of ventricular tachycardia terminated by the two techniques were comparable. Rate of success for termination of tachycardia with the two methods was also comparable (transvenous cardioversion 83%, rapid ventricular pacing 80%; p greater than .1) and these responses were concordant in 78%. The modes of termination of ventricular tachycardia were similar. The incidence of acceleration of ventricular tachycardia per episode with these preselected protocols was also comparable (transvenous cardioversion 11%, rapid ventricular pacing 6%; p greater than .2). Transient supraventricular tachyarrhythmias were more frequent after transvenous cardioversion (23%) than after rapid ventricular pacing (3%). Significant patient discomfort occurred only after transvenous cardioversion (incidence of 57%).(ABSTRACT TRUNCATED AT 250 WORDS)
AND FIBRINOLYSIS IN INTACT AND THYMECTOMIZED RATS (1983)

Altogether 93 male rats were used. The thymus was removed from 61 of the animals at the age of 1.5-2 months, and the other 32 rats remained intact. The experiments were carried out 2-3 months after the operation. Histamine was injected in a dose of 0.00012 mg/kg body weight into all animals and 26 of the thymectomized rats received an injection of thymaline in 0.5% procaine solution (i mg per rat) in the course of 1 week. The blood clotting plasma recalcification, cephalin, kaolin, prothrombin, and thrombin times, activity of factors V and VII, total antithrombin activity, fibrinogen concentration, euglobulin lysis time, and Hageman-dependent fibrinolysis of control and thymectomized animals were determined and the ethanol test carried out [2]. These parameters were studied i0 min after injection of histamine. Intact and thymectomized rats (receiving or not receiving thymaline), into which the corresponding volume of physiological saline was injected instead of histamine, served as the control. EXPERIMENTAL RESULTS The rats developed marked hypercoagulation 2-3 months after thymectomy: The blood clotting and plasma recalcification times and the kaolin and cephalin times were shortened, the concentrations of factors V and VII were increased, the prothrombin and thrombin time were reduced, and the fibrinogen concentration increased. The development of hypercoagulation after thymectomy in the rats can be attributed primarily to shortening of the first phase of blood clotting -- prothrombinase formation. Evidence in support of this view is given by the increase in concentrations of factors V and VII and the decrease in the prothrombin, kaolin, and cephalin times. Moreover, in the thymectomized rats total and Hageman-dependent euglobulin fibrinolysis was inhibited, possibly on account of a decrease in the activating and an increase in the inhibitory component of fibrinolytic activity of the blood. Injection of thymaline for 1 week into the thymectomized animals as a rule restored these parameters of blood clotting and fibrinolysis to the characteristic values for intact
Integrating parametric and non-parametric models for scene labeling (2015)

We adopt Convolutional Neural Networks (CNN) as our parametric model to learn discriminative features and classifiers for local patch classification. As visually similar pixels are indistinguishable from local context, we alleviate such ambiguity by introducing a global scene constraint. We estimate the global potential in a non-parametric framework. Furthermore, a large margin based CNN metric learning method is proposed for better global potential estimation. The final pixel class prediction is performed by integrating local and global beliefs. Even without any post-processing, we achieve state-of-the-art performance on SiftFlow and competitive results on Stanford Background benchmark.
Chemical synthesis of marine saponins (2018)

Covering: 1989-2017 Saponins are characteristic metabolites of starfish and sea cucumbers, and occasionally are also found in sponges, soft coral, and small fish. These steroid or triterpenoid glycosides often show remarkable biological and pharmacological activities, such as antifungal, antifouling, shark repellent, antitumor and anti-inflammatory activities. Over one thousand marine saponins have been characterized; the majority of them can be categorized into three major structural types, i.e., asterosaponins, polyhydroxysteroid glycosides, and holostane glycosides. Thus far, only 12 marine saponins have been synthesized; those representing the major types were successfully synthesized recently. The syntheses involve preparation of the aglycones from the terrestrial steroid or triterpene materials, installation of the carbohydrate units, and manipulation of the protecting groups. Herein, we provide a comprehensive review on these syntheses.
Atoms of All Channels, Unite! Average Case Analysis of Multi-Channel Sparse Recovery Using Greedy Algorithms (2008)

This paper provides new results on computing simultaneous sparse approximations of multichannel signals over redundant dictionaries using two greedy algorithms. The first one, p-thresholding, selects the S atoms that have the largest p-correlation while the second one, p-simultaneous matching pursuit (p-SOMP), is a generalisation of an algorithm studied by Tropp in (Signal Process. 86:572–588, 2006). We first provide exact recovery conditions as well as worst case analyses of all algorithms. The results, expressed using the standard cumulative coherence, are very reminiscent of the single channel case and, in particular, impose stringent restrictions on the dictionary. We unlock the situation by performing an average case analysis of both algorithms. First, we set up a general probabilistic signal model in which the coefficients of the atoms are drawn at random from the standard Gaussian distribution. Second, we show that under this model, and with mild conditions on the coherence, the probability that p-thresholding and p-SOMP fail to recover the correct components is overwhelmingly small and gets smaller as the number of channels increases. Furthermore, we analyse the influence of selecting the set of correct atoms at random. We show that, if the dictionary satisfies a uniform uncertainty principle (Candes and Tao, IEEE Trans. Inf. Theory, 52(12):5406–5425, 2006), the probability that simultaneous OMP fails to recover any sufficiently sparse set of atoms gets increasingly smaller as the number of channels increases.

Light‐activated gene transduction enhances adeno‐associated virus vector–mediated gene expression in human articular chondrocytes (2002)

UV light at doses of up to 200 J/m(2) (which do not significantly affect cell viability) significantly enhances the transduction efficiency and expression of the transduced gene in cultures of rAAV-infected primary chondrocytes and in chondrocytes in the superficial zone of intact articular cartilage. These findings support the concept that UV-activated gene transduction could be used as an adjuvant for in vivo rAAV articular cartilage gene therapy with low viral titers to prevent and/or treat arthritis.
FTIR Study of CO<sub>2</sub> Adsorption on Amine-Grafted SBA-15: Elucidation of Adsorbed Species (2011)

The interaction between amines and CO2 offers a possible route for the catalytic activation of CO2. In situ infrared spectroscopy was used to study the interaction of CO2 with amine-grafted SBA-15. We employed three different types of amine-grafted SBA-15 surfaces to quantify the effect distinct tethered amine moieties have on the chemistry of CO2 interacting with amine-grafted SBA-15. When the SBA-15 surface has a low density of amines and is “capped” to mitigate against interactions with surface-bound moieties, no new chemical species are observed on exposure to carbon dioxide. An ionic carbamate and a surface-bound carbamate are observed on the other SBA-15 surfaces on exposure to CO2. The formation of carbamates decreases the bond order of the carbon oxygen bond of the carbon dioxide molecule. The role of the different amine moieties and the surface silanol groups in the formation of the carbamates is discussed. Our results suggest that controlling the local environment around surface-grafted amines, which could be achieved by the use of suitably engineered surface environments, could facilitate the adsorption and activation of CO2.
