Online stator winding fault diagnosis in inverter-fed ac machines using high-frequency signal injection (2003)

The diagnosis of stator winding faults in inverter-fed AC machines using an injected high-frequency carrier signal is presented and analyzed in this paper. Measurement of the resulting high-frequency negative-sequence current (or alternatively of the negative-sequence impedance) is used to detect turn faults at an incipient stage. Though sharing the same physical principles of similar techniques applied to line-connected machines, the use of a high-frequency signal is shown to present important advantages, such as providing the same performance almost independently of the fundamental excitation frequency, and drastically reducing the sensitivity to the working condition of the machine, i.e., torque and flux levels.
Power, structural and noise performance tests on different wind turbine rotor blade designs (2011)

Most blades available for commercial-grade wind turbines incorporate a straight, span-wise profile and airfoil-shaped cross-sections. These blades are found to be very efficient at low and medium wind speeds compared with the potential energy that can be extracted. This paper explores the possibility of increasing the efficiency of the blades by modifying the blade design to incorporate a swept edge. The design intends to maintain efficiency at low to medium wind speeds by selecting the appropriate orientation and size of the airfoil cross-sections based on an oncoming wind speed and given constant rotation rate. The torque generated from a blade with straight-edge geometry is compared with that generated from a blade with a swept edge as predicted by CFD simulations. To validate the simulations, the experimental curve of the NTK500/41 turbine using LM19.1 blades is reproduced using the same computational conditions. In addition, structural deformations, stress distributions and structural vibration modes are compared between these two different turbine blade surfaces.

Abstract 11822: Pivotal Trial of a Deep-Learning-Based Retinal Biomarker (Reti-CVD) in the Prediction of Cardiovascular Disease: Data From CMERC-HI (2022)

Introduction: The Korean Ministry of Food and Drug Safety (K-MFDS) has authorized over 110 artificial intelligence (AI)-software as medical devices (AI-SaMDs) for diagnostic purposes. Herein, we clinically validate the efficacy of a three-tier cardiovascular disease (CVD) risk stratification system developed using Reti-CVD, an AI-SaMD that utilizes retinal images to estimate CVD risk. The aim of this study is to evaluate the efficacy of RetiCVD in predicting future CVD risk based on retrospective analysis of a prior prospective cohort study. Methods: This clinical study was a single-center, retrospective, conformity-design, confirmatory analysis of prior prospective cohort study. For primary endpoint, retinal images were evaluated by Reti-CVD to validate its three-tier CVD risk stratification system. For secondary endpoints, cardiac CT-measured coronary artery calcium (CAC, 0, &gt;0-100, and &gt;100), carotid intima-media thickness (CIMT, &lt;90 th and ≥90 th percentile), and brachial-ankle pulse wave velocity (baPWV, &lt;1800 and ≥1800 cm/s) were also measured as independent variables for future CVD risk. The cumulative incidence of non-fatal and/or fatal CVD events was evaluated. Cox proportional hazards models were used to estimate the hazard ratios (HR) trends. Results: In this clinical cohort (n=1106), 33 (3.0%) participants had non-fatal or fatal CVD events over 5 years, and RetiCVD scores were significantly associated with increased CVD risk (HR trend=2.02, 95% CI, 1.26-3.24). In a multivariable Cox model incorporating RetiCVD scores, CAC, CIMT, baPWV, and other traditional risk factors, RetiCVD scores for the high-risk tier were significantly associated with increased CVD risk (low risk as a reference; HR=3.56 [1.34-9.51] in high risk), while other biomarkers showed trends toward association: CAC showed a HR of 2.45 [0.88-6.84] in CAC of &gt;100 compared to zero CAC (reference); CIMT showed a HR of 1.50 (0.64-3.51) in CIMT of ≥90 th percentile compared to &lt;90 th percentile; and baPWV showed a HR of 1.27 (0.53-3.03) in baPWV of ≥1800 compared to &lt;1800 cm/s. Conclusions: This is the first K-MFDS approved AI-software that can potentially stratify future risk as biomarkers, which can have major implications such as identifying high-risk individuals.
Development of a swing estimation method using dynamic model and vibration analysis of torque during swing (2020)

In the sport of golf, the use of an appropriate club is of paramount importance. Hence, we developed a method to determine the optimal weight of a suitable club for an individual golfer. The ultimate goal of this method is to estimate changes in the swing when the club characteristics are changed and to fit the club to the golfer’s needs. To this end, it is first necessary to study the swing behavior of clubs of different types, based on standard club parameters. This report focuses on the measurement and estimation of the swing behavior of clubs of different weights. The first step of this study was to measure the swing of clubs of different weights and calculate the torque exerted during the swing. Then, power spectral density (PSD) values were obtained by performing fast Fourier transformations (FFT) on the obtained torque data. The PSD values for the different club weights were compared, and based on this comparison, the PSD values were corrected by applying an amplification function. The inverse Fourier transformation was then applied to the corrected PSD values to obtain estimated torque data. Finally, using the estimated torque data and performing forward dynamics calculations, the change in swing behavior was analyzed.
The guinea pig as a model of infectious diseases. (2008)

The words 'guinea pig' are synonymous with scientific experimentation, but much less is known about this species than many other laboratory animals. This animal model has been used for approximately 200 y and was the first to be used in the study of infectious diseases such as tuberculosis and diphtheria. Today the guinea pig is used as a model for a number of infectious bacterial diseases, including pulmonary, sexually transmitted, ocular and aural, gastrointestinal, and other infections that threaten the lives of humans. Most studies on the immune response to these diseases, with potential therapies and vaccines, have been conducted in animal models (for example, mouse) that may have less similarity to humans because of the large number of immunologic reagents available for these other species. This review presents some of the diseases for which the guinea pig is regarded as the premier model to study infections because of its similarity to humans with regard to symptoms and immune response. Furthermore, for diseases in which guinea pigs share parallel pathogenesis of disease with humans, they are potentially the best animal model for designing treatments and vaccines. Future studies of immune regulation of these diseases, novel therapies, and preventative measures require the development of new immunologic reagents designed specifically for the guinea pig.
Proceedings of the first ACM workshop on Smart energy grid security (2013)

Welcome to the first Smart Energy Grid Security Workshop -- SEGS'13. SEGS'13 is held in conjunction with the 20th ACM Conference on Computer and Communications Security in Berlin on November 8, 2013.

Recently, interest in smart grids has increased dramatically. Since the power grid is one of the most critical and pervasive infrastructures in modern societies, security and privacy are of great importance and are non-negotiable requirements to enable a large scale rollout of the smart grid. At the same time, classical security controls from the IT world often cannot be easily adapted to function in a smart grid setting where geographical distribution, resources, protection goals, and potential impact of an incident impose new challenges for security research. In this workshop, we aim to give academia a forum to present their ideas, and additionally involve different stakeholders in the power industry to foster future collaboration and help researchers focus on applicable solutions.

The SEGS'13 call for papers attracted 27 submissions from Asia, Europe, South America, and North America. program committee carefully reviewed all of the submissions and accepted the top 12 research papers covering monitoring, standards, privacy, and protocols for the smart grid. program also includes a keynote speech by Erwin Kooi from Alliander on The Future of Smart Grids and a panel titled Aligning Academia and Industry featuring power industry experts Michael John from Elster, Erwin Kooi, and Jos Weyers from TenneT.
The Influence of Flow Instability on the Lock-In of Distributed Elastic Resonators (2008)

Lock-in occurs between many different types of flow instabilities and structural-acoustic resonators. Factors that describe the coupling between the fluid and structure have been defined for low flow Mach numbers. This paper discusses how different flow instabilities influence lock-in experimentally and analytically. A key concept to the lock-in process is the relative source generation versus dissipation. The type of fluid instability source dominates the generation component of the process, so a comparison between a cavity shear layer instability with a relatively stronger source, for example wake vortex shedding from a bluff body, will be described as a coupling factor. In the fluid-elastic cavity lock-in case, the shear layer instability produced by flow over a cavity couples to the elastic structure containing the cavity. In this study, this type of lock-in was not achieved experimentally. A stronger source, vortex shedding from a bluff body however, is shown experimentally to locks into the same resonator. This study shows that fluid-elastic cavity lock-in is unlikely to occur given the critical level of damping that exists for a submerged structure and the relatively weak source strength that a cavity produces. Also in this paper, a unified theory is presented based on describing functions, a nonlinear control theory used to predict limit cycles of oscillation, where a self-sustaining oscillation or lock-in is possible. The describing function models capture the primary characteristics of the instability mechanisms, are consistent with Strouhal frequency concepts, capture damping, and are consistent with mass-damping concepts from wake oscillator theory. This study shows a strong consistency between the analytical models and experimental results.

Letters to the Editor: Local cooling for traumatic spinal cord injury (2014)

The authors describe the long-term clinical outcome in 20 patients who had American Spinal Injury Association Impairment Scale (AIS) Grade A SCI in either the cervical spine (n = 14) or thoracic spine (n = 6).This report includes the 10 patients described by the author in a previous report in 1984. 12The patients were accrued for 10 years starting from 1977 with a mean follow-up of around 5 years.Dexamethasone was given to patients for 18 days.A local cooling apparatus placed in the epidural space cooled the dura to 6°C for up to 4 hours while the instrumentation was being done after decompression.Overall, 65% of the patients improved from AIS Grade A to B, C, or D, with 2 patients regaining ambulatory function.The outcomes reported in this study are better than what would usually be expected for an AIS Grade A injury. 7 Local spinal cord cooling was more popular in 1970s and early 1980s when several groups had used local cooling in humans and animals with variable but generally good results. 3,4,8,10,11,16,18,20,21 The potential benefits of providing hypothermia directly to the injured region obviated many of the risks of deep systemic hypothermia and resulted in many studies in large animals, leading to application in humans.Local cooling trials for SCI in humans in that era were facilitated by the common performance of laminectomy as part of the treatment regimen.Wide laminectomy particularly after cervical injuries is now much less common, particularly with the advent of anterior cervical plating for cervical fracture-dislocations. 19 While the outcomes of some of these studies were encouraging, several factors, like the lack of control group, variable treatment window, confounding variables such as the administration of steroids, and small sample size led to failure in drawing any strong conclusions and gradual abandonment of local hypothermia for SCI.In contrast, there is very encouraging data from our center that modest systemic hypothermia (32°-34°C) can lead to both histological and functional recovery after SCI in animal models. 2,14,15,17,22 We have reported our technique and clinical data on the outcome and safety profile of modest systemic hypothermia for 48 hours after cervical AIS Grade A SCI. 1,5,6,13,15 In our initial study, 6 of

Alterations of p14ARF, p53, and p73 genes involved in the E2F-1-mediated apoptotic pathways in non-small cell lung carcinoma. (2001)

Overexpression of E2F-1 induces apoptosis by both a p14ARF-p53- and a p73-mediated pathway. p14ARF is the alternate tumor suppressor product of the INK4a/ARF locus that is inactivated frequently in lung carcinogenesis. Because p14ARF stabilizes p53, it has been proposed that the loss of p14ARF is functionally equivalent to a p53 mutation. We have tested this hypothesis by examining the genomic status of the unique exon 1beta of p14ARF in 53 human cell lines and 86 primary non-small cell lung carcinomas and correlated this with previously characterized alterations of p53. Homozygous deletions of p14ARF were detected in 12 of 53 (23%) cell lines and 16 of 86 (19%) primary tumors. A single cell line, but no primary tumors, harbored an intragenic mutation. The deletion of p14ARF was inversely correlated with the loss of p53 in the majority of cell lines (P = 0.02), but this relationship was not maintained among primary tumors (P = 0.5). E2F-1 can also induce p73 via a p53-independent apoptotic pathway. Although we did not observe inactivation of p73 by either mutation or DNA methylation, haploinsufficiency of p73 correlated positively with either p14ARF or p53 mutation or both (P = 0.01) in primary non-small cell lung carcinomas. These data are consistent with the current model of p14ARF and p53 interaction as a complex network rather than a simple linear pathway and indicate a possible role for an E2F-1-mediated failsafe, p53-independent, apoptotic pathway involving p73 in human lung carcinogenesis.
Symptomatic overlap between irritable bowel syndrome and microscopic colitis (2006)

In this population-based cohort of histologically confirmed microscopic colitis, approximately one-half met symptom-based criteria for the diagnosis of irritable bowel syndrome. The clinical symptom-based criteria for irritable bowel syndrome are not specific enough to rule out the diagnosis of microscopic colitis. Therefore, patients with suspected diarrhea-predominant irritable bowel syndrome should undergo biopsies of the colon to investigate for possible microscopic colitis if symptoms are not well controlled by antidiarrheal therapy.
An Antiviral Role for TRIM14 in Ebola Virus Infection (2023)

Ebola virus (EBOV) is a highly pathogenic virus that encodes 7 multifunctional structural proteins. Multiple host factors have been reported to interact with the EBOV proteins. Here, we found that tripartite motif-containing 14 (TRIM14), an interferon-stimulated gene that mediates cellular signaling pathways associated with type I interferon and inflammatory cytokine production, interacts with EBOV nucleoprotein to enhance interferon-β (IFN-β) and nuclear factor-κB (NF-κB) promotor activation. Moreover, TRIM14 overexpression reduced viral replication in an infectious but biologically contained EBOVΔVP30 system by approximately 10-fold without affecting viral protein expression. Furthermore, TRM14-deficient mice were more susceptible to mouse-adapted EBOV infection than wild-type mice. Our data suggest that TRIM14 is a host factor with anti-EBOV activity that limits EBOV pathogenesis.
A Novel Enhanced Oil Recovery Technique: Experimental Results and Modelling Workflow of the DME Enhanced Waterflood Technology (2015)

Abstract Dimethyl Ether Enhanced Waterflood (DEW) is a novel and promising solvent-based EOR technology developed by Shell. Dimethyl Ether (DME) is a widely-used industrial chemical which is applied as a water soluble solvent for EOR applications to enhance a conventional waterflood. Once the DME-brine solution is injected into the reservoir and comes in contact with the oil, the DME molecules partition into the oil phase which leads to oil swelling and mobilization of residual oil. Moreover the partitioning of the DME into the oil phase decreases the oil viscosity and improves its mobility. The combination of these effects results in both a significantly higher ultimate oil recovery compared to the conventional waterflood as well as accelerated oil production at lower energy footprint compared to thermal technologies. As the solvent is water soluble, it can be very effectively back-recovered from the reservoir by re-dissolving the trapped DME in the DME-free chase water slug. The solvent is recovered from the produced oil and water streams at surface and re-used. The main objectives of this paper are to present the first experimental results, explain the physical mechanisms of this novel concept and demonstrate the extra oil recovery. Additionally, modeling workflows used to interpret the experiments and predict the benefits of field EOR application are illustrated. To gain an insight into physical mechanisms behind the DEW, develop modeling workflows and de-risk the technology, an extensive experimental program was set up to investigate both the fluid-fluid and rock-fluid interactions. Phase behavior of DME/brine and DME/crude mixtures has been carried out, with a focus on the partitioning of the solvent between brine and crude. Mixing rules for properties affecting the phase mobilities have been determined. In parallel, a number of coreflood experiments were conducted on both carbonate and clastic cores of varying permeability to investigate the dynamic DME/crude behavior and DME/rock interaction. PVT experiments were used to build phase equilibrium models. Based on these PVT models, the coreflood experimental data was matched and interpreted using numerical simulation. Coreflood experiments confirmed the phase behavior-driven character of the DEW technology. A good match between the experimental and simulated oil recovery was obtained in most cases. This shows that PVT models, generated using measured basic data, are in a good agreement with the dynamic coreflood experiments.
P‐52: High‐Gain Source Followers Driven by Corbino Oxide TFTs for Integrated Display Data Drivers (2015)

A high‐gain source follower, utilizing oxide TFTs with a Corbino (circular) structure, is reported. Given the infinite output resistance exhibited by Corbino TFTs in the outer‐drain condition (i.e., when the outer electrode is biased as the drain), the Corbino TFT‐based source follower provides higher gain in operation than its rectangular TFT‐based counterparts.
High performing 8 /spl Orang/ EOT HfO/sub 2/ / tan low thermal-budget n-channel FETs with solid-phase epitaxially regrown (SPER) junctions (2005)

We demonstrate high-performing w-channel transistors with a HfO/sub 2//TaN gate stack and a low thermal budget process (570/spl deg/C anneal). The thinnest devices have an EOT of 8.3 A, a leakage current of 2.6 A/cm/sup 2/ at V/sub G/=1 V, and a drive-current of 815 /spl mu/A/um at an off-state current of 0.1 /spl mu/A//spl mu/m for VDD=1.2 V. We show that the performance improvement over identical gate-stacks processed with a 1000/spl deg/C spike anneal is related to a difference in V/sub T/.
