Parallel processing of ECG and blood pressure waveforms for detection of acute hypotensive episodes: a simulation study using a risk scoring model (2009)

The aim of this study is to detect acute hypotensive episodes (AHE) and mean arterial pressure dropping regimes (MAPDRs) using electrocardiographic (ECG) signals and arterial blood pressure waveforms. To meet this end, the QRS complexes and end-systolic end-diastolic pulses are first extracted using two innovative modified Hilbert transform-based algorithms, namely ECGMHT and BPMHT. The resulting systolic and diastolic blood pressure pulses are then used to calculate the MAP trend. A new smoothing algorithm is developed, next based on piecewise polynomial fitting (PPF) to smooth the fast fluctuations observed in RR-tachogram and MAP trends. PPF algorithm operates by sequentially fitting N number of polynomials to the original signal and calculating the corresponding coefficients using the best linear unbiased estimation approach. In the next step, the proposed algorithm is applied to 15 subjects of the MIMIC II Database and AHE and MAPDRs (MAP ≤ 60 mmHg with a period of 30 min or more) are identified. As a result of this study, MAPDR is realised as a specific marker of cardiogenic shock, in that for a sequence of MAPDRs as long as 20 min or more, there will exist a consequent high peak with a duration of 3-4 min in the corresponding probability of cardiogenic shock diagram.
Discrete event simulation for quick service restaurant traffic analysis (1994)

This paper describes the development of a software tool that simulates and animates the traffic control in and around parking lots associated with quick service restaurants (QSR). The Quick Service Restaurant Simulation (QSRS) module provides restaurant planners and designers with the ability to experiment with various parking lot and adjacent street traffic configurations in an effort to optimize proposed sites or to improve existing ones. QSRS was designed to consider all of the important traffic parameters of a restaurant site in a flexible, user friendly environment. Each site's parameters can be varied and modified to make quantitative comparisons of proposed solutions to determine optimal site design. The QSRS module provides high quality 3-D graphics with accurate spatial representation, allowing the user to visually observe the site in operation for verification of proposed configurations. QSRS is currently being used at Taco Bell Corporation for three primary uses: post-construction fixes; development of standard layouts for site design standardization; and strategic permitting by visually communicating the proposed development to the community.
Insulin-mimetic effects of vanadate in isolated rat adipocytes (1980)

The effects of vanadate on hexose transport and (Na/sup +/-K/sup +/)ATPase function in isolated rat adipocytes were characterized. Incubation of these cells with vanadate elicited an insulin-like stimulation of the rate of glucose oxidation and 2-deoxyglucose transport, the magnitude of which was dependent on both the extracellular vanadate concentration and the duration of the incubation. The maximal 6- to 12-fold stimulation of transport observed in vanadate-treated adipocytes was equivalent to that produced by a maximally activating concentration of insulin. Vanadate produced no additional activation of sugar transport in adipocytes pretreated with a maximally activating concentration of insulin. Incubation of adipocytes with concentrations of vanadate which significantly stimulated sugar transport produced no inhibition of (Na/sup +/-K/sup +/)ATPase function measured as the rate of /sup 86/Rb/sup +/ uptake. The uptake of (/sup 48/V)-vanadate by adipocytes was linear for at least 3 h and exceeded the calculated equilibrium space. Progressive stimulation of the 2-deoxyglucose transport rate was correlated with the apparent vanadate content of the cells during prolonged incubation with (/sup 48/V) vanadate. The effects of vanadate on sugar transport were reversed by washing the cells in vanadate-free medium; the degree of reversibility was dependent on the duration of the cells' exposure tomore » vanadate. These findings suggest that adipocytes convert accumulated vanadate to a form (perhaps vanadyl) incapable of inhibiting the (Na/sup +/-K/sup +/)ATPase; in the course of this intracellular conversion, however, the insulin-sensitive hexose transport system is activated.« less
Hard‐tissue alterations following immediate implant placement in extraction sites (2004)

The marginal gap that occurred between the metal rod and the bone tissue following implant installation in an extraction socket may predictably heal with new bone formation and defect resolution. The current results further documented that marginal gaps in buccal and palatal/lingual locations were resolved through new bone formation from the inside of the defects and substantial bone resorption from the outside of the ridge.
Activation of <i>RAS</i> Family Genes in Urothelial Carcinoma (2009)

Our results underline the importance of H-RAS activation in human bladder cancer by codon 12 mutations. Moreover, they provide evidence that increased expression of all 3 RAS genes is a common event in bladder cancer that is associated with disease development.
Reconfigurable Closed-Loop Digital ΔΣ CapacitiveMEMS Accelerometer for Wide Dynamic Range, HighLinearity Applications (2013)

Closed-loop capacitive MEMS accelerometer is similar to a ΔΣ ADC where the MEMS sensor introduces second-order dynamics in the loop. The sensor has limited signal gain, hence provides very limited noise shaping capability to other noise contributions within the loop. Furthermore, fabrication non-idealities can cause unwanted stability issues in higher order closed-loop operation. We present a 4 th order ΔΣ closed-loop system with a digital 2 nd order ΔΣ modulator. The digital ΔΣ modulator allows fine accuracy in choosing the coefficients for the ΔΣ modulators. It also provides flexibility in the placement of poles and zeros for compensating the unforeseen phase delays caused by fabrication non-idealities. Our system is able to achieve an SNR > 120dB in simulation and > 90dB from experiment with an evaluation board. The digital implementation of ΔΣ modulator allows us to build reconfigurable closed-loop system with the potential for even higher order system which can be optimized to suit different MEMS sensor characteristics and performance.
Changing fashions in the Swan River colony 1829-1929 (2010)

Women brought the fashion of Europe and the British Empire to the Swan River colony but the local climate dictated adaptation and improvisation as Jo Pearson discovers.
Flexural–extensional behavior of composite piezoelectric circular plates (1980)

A plate-type theory is developed for the flexural-extensional vibratory response and static voltage deformation of heterogeneous piezoelectric circular transducer elements. Known results for homogeneous disks and bimorphs are shown to be special cases of the theory. Application is made to the design of simply supported metal-piezoceramic unimorph disks, and thin piezoceramic bimorph benders possessing metallic electrodes of non-negligible thickness.
Mixed-initiative interaction = mixed computation (2002)

We show that partial evaluation can be usefully viewed as a programming model for realizing mixed-initiative functionality in interactive applications. Mixed-initiative interaction between two participants is one where the parties can take turns at any time to change and steer the flow of interaction. We concentrate on the facet of mixed-initiative referred to as 'unsolicited reporting' and demonstrate how out-of-turn interactions by users can be modeled by 'jumping ahead' to nested dialogs (via partial evaluation). Our approach permits the view of dialog management systems in terms of their support for staging and simplifying inter-actions; we characterize three different voice-based interaction technologies using this viewpoint. In particular, we show that the built-in form interpretation algorithm (FIA) in the VoiceXML dialog management architecture is actually a (well disguised) combination of an interpreter and a partial evaluator.
The role of Th1 and Th17 in the pathogenesis of celiac disease (2018)

Celiac disease is a chronic autoimmune disease that is associated with genetic, environmental and immunological factors. The disease is closely associated with genes that code for human leukocyte antigens DQ2 and DQ8 haplotypes. In general, celiac disease has been recognized as a T lymphocyte associated disorders in which proteins derived gliadins, in the form of naive or deamidated by tissue Transglutaminase, activate T lymphocytes and as a result, release proinflammatory cytokines Such as IFN, IL-17, IL-21 and etc. These cytokines lead to histopathological changes like villous atrophy and crypt hyperplasia In addition, celiac disease has a specific antibody against gluten and an autoantigen of the transglutaminase 2(TG2) that provides strong opportunities to fully understand the adaptive immune response leading to disease. In this review, we investigated the role of Th1 and Th17 as an important mediators in pathogenesis of celiac disease.
A large-scale Web data collection as a natural language processing infrastructure (2008)

In recent years, language resources acquired from theWeb are released, and these data improve the performance of applications in several NLP tasks. Although the language resources based on the web page unit are useful in NLP tasks and applications such as knowledge acquisition, document retrieval and document summarization, such language resources are not released so far. In this paper, we propose a data format for results of web page processing, and a search engine infrastructure which makes it possible to share approximately 100 million Japanese web data. By obtaining the web data, NLP researchers are enabled to begin their own processing immediately without analyzing web pages by themselves. 1.

Synthetic Studies of Trichloroleucine Marine Natural Products. Michael Addition of LiCCl<sub>3</sub> to <i>N</i>-Crotonylcamphor Sultam (1999)

Conjugate addition of trichloromethyllithium to N-crotonylcamphorsultam occurs in good yield at −98 °C in THF−hexanes. The formal incorporation of the “CCl3-” anion by 1,4-addition allows subsequent transformation to useful trichloromethyl-substituted intermediates.
New chlorin and bacteriochlorine-type photosensitizers for photodynamic therapy (1995)

New chlorins and bacteriochlorins as perspective sensitizers for photodynamic therapy were synthesized. The influence on the position and the character of the substituents on the sensitizer optical properties was studied. The series of water soluble chlorin p6 derivatives with graded amphiphility were synthesized for studies on tumor accumulation. The influence of pH on sensitizer amphiphility was discussed. The photostability of water soluble chlorins and bacteriochlorins has been examined.
3D scan conversion of CSG models into distance volumes (1998)

A distance volume is a volume dataset where the value stored at each voxel is the shortest distance to the surface of the object being represented by the volume. Distance volumes are a useful representation in a number of computer graphics applications. We present a technique for generating a distance volume with sub-voxel accuracy from one type of geometric model, a constructive solid geometry (CSG) model consisting of superellipsoid primitives. The distance volume is generated in a two step process. The first step calculates the shortest distance to the CSG model at a set of points within a narrow band around the evaluated surface. Additionally, a second set of points, labeled the zero set, which lies on the CSG model's surface are computed. A point in the zero set is associated with each point in the narrow band. Once the narrow band and zero set are calculated, a fast marching method is employed to propagate the shortest distance and closest point information out to the remaining voxels in the volume. Our technique has been used to scan convert a number of CSG models, producing distance volumes which have been utilized in a variety of computer graphics applications, e.g. CSG surface evaluation, offset surface generation, and 3D model morphing.
Fast packet scheduling algorithm based on instantaneous SIR with constraint condition assuring minimum throughput in forward link (2004)

This paper proposes a new fast packet-scheduling algorithm based on instantaneous received signal-to-inference power ratio (SIR) with a constraint condition that assures a minimum throughput (minimum throughput assured instantaneous SIR (MTA-ISIR) method hereafter) and investigates its throughput performance in high-speed downlink packet access (HSDPA). In the proposed algorithm, packet transmission is assigned with priority based on the instantaneous received SIR for users with a larger average received SIR than the prescribed threshold value, and packet transmission is fairly assigned to users who have smaller average SIR than the threshold value by raising the instantaneous SIR corresponding to the threshold value. Computer simulation results elucidate that the number of high-rate users with a user throughput more than 2-Mbps employing the proposed MTA-ISIR method is increased by approximately 1.9 (1.5) times that using the proportional fairness method while maintaining a similar level of fairness for low-rate users when the threshold value is 18 dB in a 2(1)-path Rayleigh fading channel.
Identification of two toxins from scorpion (<i>Leiurus quinquestriatus</i>) venom which block distinct classes of calcium‐activated potassium channel (1986)

Two polypeptide toxins from scorpion (Leiurus quinquestriatus) venom which block distinct classes of calcium-activated potassium channels have been identified and partially purified. One toxin, at 50-100 ng/ml, blocks apamin-sensitive potassium fluxes in hepatocytes and inhibits [125I]monoiodoapamin binding. The other, more basic, toxin blocks apamin-insensitive potassium fluxes in erythrocytes at 200 ng/ml and, to our knowledge, is the first toxin shown to block the erythrocyte calcium-activated potassium channel with high affinity. The possible co-identity of this latter toxin with charybdotoxin is discussed.
Study of Magic-Size-Cluster Mediated Formation of CdS Nanocrystals: Properties of the Magic-Size Clusters and Mechanism Implication (2009)

The magic-size clusters (MSCs) of semiconductor nanocrystals (NCs) have attracted much attention the last few years. In this work, we studied the synthesis of CdS NCs in a liquid-paraffin/glycerol biphasic system at different temperatures. The properties of a 323-nm-absorbing MSC species, an intermediate in the synthesis, were investigated using an ultraviolet−visible (UV−vis) spectroscopic technique. Alcohol-induced transformations of the MSCs into a ∼309-nm-absorbing and/or a ∼348-nm-absorbing cluster/crystal species were studied in detail. Based on the studies, a plausible nucleation−growth mechanism was proposed for the MSC-mediated formation of CdS NCs.
A Novel Three-Dimensional Wound Healing Model (2014)

Wound healing is a well-orchestrated process, with various cells and growth factors coming into the wound bed at a specific time to influence the healing. Understanding the wound healing process is essential to generating wound healing products that help with hard-to-heal acute wounds and chronic wounds. The 2D scratch assay whereby a wound is created by scratching a confluent layer of cells on a 2D substrate is well established and used extensively but it has a major limitation—it lacks the complexity of the 3D wound healing environment. Established 3D wound healing models also have many limitations. In this paper, we present a novel 3D wound healing model that closely mimics the skin wound environment to study the cell migration of fibroblasts and keratinocytes. Three major components that exist in the wound environment are introduced in this new model: collagen, fibrin, and human foreskin fibroblasts. The novel 3D model consists of a defect, representing the actual wound, created by using a biopsy punch in a 3D collagen construct. The defect is then filled with collagen or with various solutions of fibrinogen and thrombin that polymerize into a 3D fibrin clot. Fibroblasts are then added on top of the collagen and their migration into the fibrin—or collagen—filled defect is followed for nine days. Our data clearly shows that fibroblasts migrate on both collagen and fibrin defects, though slightly faster on collagen defects than on fibrin defects. This paper shows the visibility of the model by introducing a defect filled with fibrin in a 3D collagen construct, thus mimicking a wound. Ongoing work examines keratinocyte migration on the defects of a 3D construct, which consists of collagen-containing fibroblasts. The model is also used to determine the effects of various growth factors, delivered in the wound defects, on fibroblasts’ and keratinocytes’ migration into the defects. Thus this novel 3D wound healing model provides a more complex wound healing assay than existing wound models.
Leveraging Digital Twin Technology in Model-Based Systems Engineering (2019)

Digital twin, a concept introduced in 2002, is becoming increasingly relevant to systems engineering and, more specifically, to model-based system engineering (MBSE). A digital twin, like a virtual prototype, is a dynamic digital representation of a physical system. However, unlike a virtual prototype, a digital twin is a virtual instance of a physical system (twin) that is continually updated with the latter’s performance, maintenance, and health status data throughout the physical system’s life cycle. This paper presents an overall vision and rationale for incorporating digital twin technology into MBSE. The paper discusses the benefits of integrating digital twins with system simulation and Internet of Things (IoT) in support of MBSE and provides specific examples of the use and benefits of digital twin technology in different industries. It concludes with a recommendation to make digital twin technology an integral part of MBSE methodology and experimentation testbeds.
Contextual spelling correction using latent semantic analysis (1997)

Contextual spelling errors are defined as the use of an incorrect, though valid, word in a particular sentence or context. Traditional spelling checkers flag misspelled words, but they do not typically attempt to identify words that are used incorrectly in a sentence. We explore the use of Latent Semantic Analysis for correcting these incorrectly used words and the results are compared to earlier work based on a Bayesian classifier.
Using High Rydberg States as Electric Field Sensors (1999)

High Rydberg states of the krypton atom have been investigated at high resolution by vacuum ultraviolet--millimeter wave double-resonance spectroscopy. The measurement of Stark shifts in the spectra of these high Rydberg states is used to determine electric fields with a $\ifmmode\pm\else\textpm\fi{}20\ensuremath{\mu}\mathrm{V}/\mathrm{cm}$ accuracy. The analysis of spectral line shapes provides information on inhomogeneous electric field distributions in the experimental volume.
[Study of the effects of air pollution on human health in Beijing]. (1992)

3000 habitants from different polluted areas of Beijing were examined for their states of health in both the summer and the winter in 1989, and 7000 questionnaires were filled. Meanwhile, the data of air pollution surveillance during 1980 and 1988 were collected and analysed. The air pollutants in the areas have been identified. The results of the study showed that the effects of air pollution on human health in urban were more severely than that in suburb and rural area; the complaints of respiratory system were correlative with the level of pollution in the areas; and the index method is useful in the studies of the effects of multi-factor pollution of human health.
