Glucose metabolism and insulin sensitivity in Dahl hypertensiverats (1999)

There is increasing recognition that hypertension is only one facet of a metabolic syndrome that represents a cluster of risk factors including insulin resistance evident during long-term development of cardiovascular disease. The objectives of the present study were to evaluate glucose metabolism and insulin sensitivity in the Dahl genetic salt-sensitive rat model of hypertension and to find out whether there is a correlation between high blood pressure, salt sensitivity and insulin sensitivity. The experiments were performed in Wistar and Dahl salt-resistant (DSR) and salt-sensitive (DSS) rats given a normal or salt-loaded (2% NaCl in the drinking water) diet for 2 months. Glucose turnover, metabolic clearance of glucose and insulin sensitivity were determined using the euglycemic clamp technique in anesthetized animals. Four different concentrations of insulin were used (2.1, 4.2, 8.4 and 16.8 mg/kg/min) with results showing that there were no significant differences in serum glucose and insulin levels, glucose utilization and clearance and insulin sensitivity between Wistar and DSR; these groups remained normotensive throughout the 2-month experiment. However, DSS rats, even on a normal diet, developed hypertension by the end of the experiment and consistent with their hypertensive condition, significantly decreased glucose utilization and clearance and decreased insulin sensitivity were observed. The changes were more marked at higher insulin infusion rates (8.4 and 16.8 mg/kg/min). These results demonstrate that DSS rats with fully developed hypertension were insulin resistant. In contrast, DSR rats remained normotensive despite sodium loading. Sodium loading significantly exaggerated the hypertensive state of DSS rats but did not further increase insulin resistance. The results from respective weanling rats showed that even at this early stage before development of hypertension, DSS rats already had significantly increased serum insulin suggesting insulin resistance. In conclusion, the present results suggest that DSR genetically hypertensive rats were insulin resistant although insulin resistance was unrelated to high blood pressure or NaCl intake.
A Distributed Parameter Electromechanical Model for Cantilevered Piezoelectric Energy Harvesters (2008)

Cantilevered beams with piezoceramic layers have been frequently used as piezoelectric vibration energy harvesters in the past five years. The literature includes several single degree-of-freedom models, a few approximate distributed parameter models and even some incorrect approaches for predicting the electromechanical behavior of these harvesters. In this paper, we present the exact analytical solution of a cantilevered piezoelectric energy harvester with Euler–Bernoulli beam assumptions. The excitation of the harvester is assumed to be due to its base motion in the form of translation in the transverse direction with small rotation, and it is not restricted to be harmonic in time. The resulting expressions for the coupled mechanical response and the electrical outputs are then reduced for the particular case of harmonic behavior in time and closed-form exact expressions are obtained. Simple expressions for the coupled mechanical response, voltage, current, and power outputs are also presented for excitations around the modal frequencies. Finally, the model proposed is used in a parametric case study for a unimorph harvester, and important characteristics of the coupled distributed parameter system, such as short circuit and open circuit behaviors, are investigated in detail. Modal electromechanical coupling and dependence of the electrical outputs on the locations of the electrodes are also discussed with examples.

Unraveling the Activation Mechanism of Taspase1 which Controls the Oncogenic AF4–MLL Fusion Protein (2015)

We have recently demonstrated that Taspase1-mediated cleavage of the AF4-MLL oncoprotein results in the formation of a stable multiprotein complex which forms the key event for the onset of acute proB leukemia in mice. Therefore, Taspase1 represents a conditional oncoprotein in the context of t(4;11) leukemia. In this report, we used site-directed mutagenesis to unravel the molecular events by which Taspase1 becomes sequentially activated. Monomeric pro-enzymes form dimers which are autocatalytically processed into the enzymatically active form of Taspase1 (αββα). The active enzyme cleaves only very few target proteins, e.g., MLL, MLL4 and TFIIA at their corresponding consensus cleavage sites (CSTasp1) as well as AF4-MLL in the case of leukemogenic translocation. This knowledge was translated into the design of a dominant-negative mutant of Taspase1 (dnTASP1). As expected, simultaneous expression of the leukemogenic AF4-MLL and dnTASP1 causes the disappearance of the leukemogenic oncoprotein, because the uncleaved AF4-MLL protein (328 kDa) is subject to proteasomal degradation, while the cleaved AF4-MLL forms a stable oncogenic multi-protein complex with a very long half-life. Moreover, coexpression of dnTASP1 with a BFP-CSTasp1-GFP FRET biosensor effectively inhibits cleavage. The impact of our findings on future drug development and potential treatment options for t(4;11) leukemia will be discussed.
Function of hisF and hisH gene products in histidine biosynthesis. (1994)

A mutant of the enterobacterium Klebsiella pneumoniae with a defect in the hisF gene (in the histidine biosynthesis pathway) was isolated, which can only grow with high but not low ammonia concentrations. The mutated hisF product can use ammonia for the formation of the imidazole ring of histidine but not glutamine provided by the hisH product. Site-directed insertional mutagenesis of hisH led to the same dependence of prototrophic growth on high ammonia levels. The nucleotide sequence of K. pneumoniae hisF is almost identical to that of hisF from other enterobacteria. Similarities of the hisF product with the hisA product and of HisH sequences with the glutamine binding domains of TrpG-type amidotransferases provide additional evidence for the functions of the hisF and hisH products in histidine biosynthesis, namely that HisF catalyzes the ammonolytic cleavage of N'-(5'-phosphoribulosyl)-formimino-5- aminoimidazole-4-carboxamide ribonucleotide either utilizing free ammonia or deriving the ammonia moiety from glutamine bound to HisH.
Relation of Bacterial Settlement Patterns to Anodic Activity on Stainless Steel Weldments (1999)

Abstract Bacterial settlement on welded stainless steel samples exposed to seawater occurred more rapidly in the heat-affected zone (HAZ) and the root of the weld as compared to the parent metal. Preferential attachment of bacteria to a network of surface cracks was an occasional feature, which became more conspicuous during mild anodic polarization of the samples. In a less corrosive fresh water system, bacterial settlement was more random, until application of anodic polarization which triggered bacterial settlement patterns analogous to the sea water system. Supplementary experiments on bacterial response to pre-initiated corrosion sites in the form of pits and scratches reinforced the idea that bacteria preferentially colonize areas of anodic electrochemical activity and/or metal ion release.
HUMAN TOLERANCE TO MAGNETIC FIELDS (1962)

BS>The physiological and psychological effects of magnetic fields on man were studied. There was no sensation in part and entire body exposure to non- changing fields up to 20 kilogauss for a duration of 15 minutes, and no after- effects following exposure to fields of 5 kilogauss for less than three days per year per man. However, taste and pain sensation may be caused by fillings of the teeth in high strength fields. Visual sensations are also noticed in alternating fields. (N.W.R.)
Nonideal magnetohydrodynamic instabilities and toroidal magnetic confinement (1985)

The marked divergence of experimentally observed plasma instability phenomena from the predictions of ideal magnetohydrodynamics led in the early 1960’s to the formulation of finite-resistivity stability theory. Beginning in the 1970’s, advanced plasma diagnostics have served to establish a detailed correspondence between the predictions of the finite-resistivity theory and experimental plasma behavior—particularly in the case of the resistive kink mode and the tokamak plasma. Nonlinear resistive-kink phenomena have been found to govern the transport of magnetic flux and plasma energy in the reversed-field pinch. The other predicted finite-resistivity instability modes have been more difficult to identify directly, and their implications for toroidal confinement are still unresolved.
Repeatability of scores on a novel test of endurance running performance (2008)

The aim of the present study was to determine the repeatability of a running endurance test using an automated treadmill system that requires no manual input to control running speed. On three separate occasions, 7 days apart, 10 experienced male endurance-trained runners (mean age 32 years, s = 10; VO2peak 61 ml x kg(-1) x min(-1), s = 7) completed a treadmill time trial, in which they were instructed to run as far as possible in 60 min. The treadmill was instrumented with an ultrasonic feedback-controlled radar modulator that spontaneously regulated treadmill belt speed corresponding to the changing running speed of each runner. Estimated running intensity was 70% VO2peak (s = 11) and the distance covered 13.5 km (s = 2), with no difference in mean performances between trials. The coefficient of variation, estimated using analysis of variance, with participant and trial as main effects, was 1.4%. In summary, the use of an automated treadmill system improved the repeatability of a 60-min treadmill time trial compared with time trials in which speed is controlled manually. The present protocol is a reliable method of assessing endurance performance in endurance-trained runners.
Region based /spl alpha/-semantics graph driven image retrieval (2004)

This work is about content based image database retrieval, focusing on developing a classification based methodology to address semantics-intensive image retrieval. With self organization map based image feature grouping, a visual dictionary is created for color, texture, and shape feature attributes, respectively. Labeling each training image with the keywords in the visual dictionary, a classification tree is built. Based on the statistical properties of the feature space we define a structure, called /spl alpha/-semantics graph, to discover the hidden semantic relationships among the semantic repositories embodied in the image database. With the /spl alpha/-semantics graph, each semantic repository is modeled as a unique fuzzy set to explicitly address the semantic uncertainty and the semantic overlap existing among the repositories in the feature space. A retrieval algorithm combining the built classification tree with the developed fuzzy set models to deliver semantically relevant image retrieval is provided. The experimental evaluations have demonstrated that the proposed approach models the semantic relationships effectively and outperforms a state-of-the-art content based image retrieval system in the literature both in effectiveness and efficiency.
A novel feature transformation for vocal tract length normalization in automatic speech recognition (1998)

This paper proposes a method to transform acoustic models that have been trained with a certain group of speakers for use on different speech in hidden Markov model based (HMM-based) automatic speech recognition. Features are transformed on the basis of assumptions regarding the difference in vocal tract length between the groups of speakers. First, the vocal tract length (VTL) of these groups has been estimated based on the average third formant F/sub 3/. Second, the linear acoustic theory of speech production has been applied to warp the spectral characteristics of the existing models so as to match the incoming speech. The mapping is composed of subsequent nonlinear submappings. By locally linearizing it and comparing results in the output, a linear approximation for the exact mapping was obtained which is accurate as long as the warping is reasonably small. The feature vector, which is computed from a speech frame, consists of the mel scale cepstral coefficients (MFCC) along with delta and delta/sup 2/-cepstra as well as delta and delta/sup 2/ energy. The method has been tested for TI digits data base, containing adult and children speech, consisting of isolated digits and digit strings of different length. The word error rate when trained on adults and tested on children with transformed adult models is decreased by more than a factor of two compared to the nontransformed case.
Inspection, Identification and Repair Monitoring of Cracked Concrete structure –An application of Image processing (2018)

The aim of this research is to identify the cracks on concrete walls and classify them into voids, cracks and micro thin cracks. It is imperative to plan an optimal repair technique that considers the necessary causes and problems that require special attention during repair. The proposed framework integrates Unmanned Aerial Vehicles (UAVs), data acquisition procedures and image processing for crack detection and evaluation of surface degradation. An ideal approach is implemented, Speeded Up Robust Features (SURF) and Scale-Invariant Feature Transform (SIFT) techniques are used for crack detection. The acquired images are section-overlapped and stitched together using image stitching program. In addition to the aforementioned strategies, gray-scale thresholding (where gray-scale is converted into binary) is a technique that is utilized for measurement of surface deterioration.
Range Data Registration Using Photometric Features (2005)

This paper investigates the use of photometric features for the pair-wise registration of range images. Many artificial and natural objects exhibit abundant surface texture that may not be revealed in range data, and most structured light and laser range sensors are capable of capturing either grayscale or color photometric intensity in addition to range data. Nevertheless, the use of photometric features has not been widely investigated for range data registration, despite widespread research into local feature descriptors for object recognition in 2D photometric images. This paper addresses some of the problems that arise in using photometric features for range data registration, and presents a systematic method for their use. Potentially useful photometric features are detected on planar regions in 3D, and then reprojected to 2D to remove the perspective distortion. Then, a well-established 2D rotation- and brightness-invariant image feature descriptor is used for matching. Range data alignment is performed using a RANSAC algorithm, with verification performed in 3D. Experimental results demonstrate the effectiveness of this method.

Numerical Analysis of the Photoeffects in GaAs (1992)

The photoeffects on the I-V characteristics of GaAs MESFET's have been studied by a two-dimensional numerical method. It is theoretically verified that the photovoltaic effect occurring at the channel/substrate interface is responsible for the substantial increase of the drain current. The reverse gate current due to illumination is caused by sweep-out by the high electrical field in the gate depletion region, where a large gra- dient in the depth profile of the hole Fermi energy is found. For devices with a lightly doped n-type buffer layer, the increase of the drain current is less than for devices without a buffer layer, but is still substantial.

36-GHz-bandwidth quad-channel driver module using compact QFN package for optical coherent systems (2015)

This paper presents a small quad-channel driver module for optical modulators in digital coherent systems. To decrease the size of the module, we designed a compact quad-channel package. The size of the package is 14 × 8 × 2.8 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> . The bandwidth of the driver module is 36 GHz with maximum differential gain of 15 dB. Waveforms with clear eye-openings at symbol rates of 32 and 50 Gbaud were observed. To the best of our knowledge, this is the most compact quad-channel driver module in 50-Gbaud class.

Wireality: Enabling Complex Tangible Geometries in Virtual Reality with Worn Multi-String Haptics (2020)

Today's virtual reality (VR) systems allow users to explore immersive new worlds and experiences through sight. Unfortunately, most VR systems lack haptic feedback, and even high-end consumer systems use only basic vibration motors. This clearly precludes realistic physical interactions with virtual objects. Larger obstacles, such as walls, railings, and furniture are not simulated at all. In response, we developed Wireality, a self-contained worn system that allows for individual joints on the hands to be accurately arrested in 3D space through the use of retractable wires that can be programmatically locked. This allows for convincing tangible interactions with complex geometries, such as wrapping fingers around a railing. Our approach is lightweight, low-cost, and low-power, criteria important for future, worn consumer uses. In our studies, we further show that our system is fast-acting, spatially-accurate, high-strength, comfortable, and immersive.
