Quasi-Resonant Zero-Current-Switching Bidirectional Converter for Battery Equalization Applications (2006)

A systematic approach to reform and analyze a soft-switching bidirectional dc-to-dc converter is proposed for cell voltage balancing control in a series connected battery string. quasi-resonant converter circuits have been designed to achieve the zero-current-switching (ZCS) to reduce the switching loss in bidirectional battery equalizers. The results indicate that the switching loss and energy transfer efficiency can be substantially improved using the quasi-resonant ZCS (QRZCS) technology in a battery charging system with an individual cell equalizer (ICE). The validity of the battery equalization is further verified using an experimental installation involving a battery string of three lithium–ion cells. The simulation and experimental results show that the proposed QRZCS battery equalization schemes can achieve bidirectional battery equalization performance and reduce the MOSFET transistor switch power losses by more than 96% and increase the efficiency by around 20% <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$sim$</tex> 30% compared with the conventional battery equalizer during an identical equalization process.
Circulating autoantibodies to troponin I in Emery-Dreifuss muscular dystrophy. (2008)

The pathogenesis of dilated cardiomyopathy in Emery- Dreifuss muscular dystrophy (EDMD) is still unknown. Autoimmune mechanisms have recently been taken into account. The aim of this investigation was to determine whether the level of circulating antibodies to heart proteins which were previously detected, correlates with disease progression. Troponin I was chosen as the target. Ten patients with EDMD and 10 age-matched normal controls were tested. An enzyme linked immunoassay (ELISA) technique was used to determine the possible relation between the level of anti-troponin I antibodies at diagnosis and at followup. Autoantibodies against troponin I were detected in all EDMD patients. At diagnosis the level was higher in the X-linked EDMD form (X-EDMD), as compared to the autosomal dominant form (AD-EDMD). At follow-up the elevated level of the autoantibodies persisted in all the EDMD cases. However, in the AD-EDMD form, the level was found to be significantly rising with disease progression, in the X-EDMD form, on the other hand, it was declining. No clear-cut relationship between the level of the circulating antibodies and cardiac symptomatology was present. Detection of anti-troponin I antibodies may provide a non-invasive marker of early stages of dilated cardiomyopathy in EDMD.
Narrowband UV-B Phototherapy vs Photochemotherapy in the Treatment of Chronic Plaque-Type Psoriasis (1999)

Our data demonstrate that in many patients with plaque-type psoriasis, narrowband UV-B is comparably as effective as PUVA and, given the lack of photosensitizer-related adverse reactions and the possibly lower long-term cancer risk, can be considered as first-line treatment. Treatment with PUVA, on the other hand, remains the mainstay for patients with high PASI scores who do not respond or whose psoriasis cannot be controlled adequately by narrowband UV-B.

Dynamic analysis method of rotating shaft with magnetic pattern (2017)

Vibration issue in rotating system has existed mostly due to imbalance response of a rotating shaft. In general, accelerometers or eddy current probes are commonly used to measure the shaft’s dynamic changes in form of acceleration and displacement. Originated from coding and operating algorithm of hard disk drive, a method to detect the position error of read head is applied on measuring and analyzing dynamic response of rotating shaft system. By magnetizing the pattern on magnetic medium surrounded on the rotating shaft, analog signal can be acquired to determine the shaft’s axial and radial displacement. In this paper, a method of dynamic measuring on rotating shaft is proposed by using magnetic pattern and validated through calibrated experiments.
Suppression of simian immunodeficiency virus replication by human immunodeficiency virus type 1 trans-dominant negative rev mutants (1995)

We demonstrate that trans-dominant negative rev mutants are able to suppress simian immunodeficiency virus provirus replication in both transient cotransfection assays and stably transduced HUT 78 cells. These studies suggest that the efficacy of trans-dominant rev strategies in reducing viral burden may be evaluated in a simian immunodeficiency virus-rhesus macaque animal model.
Vision-Based Framework for Intelligent Monitoring of Hardhat Wearing on Construction Sites (2018)

The construction industry is still considered among the riskiest industries in the world because workers are continuously exposed to injury from falls, slips, or trips or being struck by falling objects. Hence, safety programs have been according great emphasis on enforcing proper use of personal protective equipment (PPE) by deploying safety officers on construction sites. However, the current practice of supervising large construction areas is still manual, tedious, and ineffective. Therefore, this study aims at creating an integrated framework that can automatically and efficiently detect any noncompliance with safety rules and regulations, in particular a failure to wear a hardhat, using computer vision techniques applied on videos captured from construction sites. This is mainly achieved by (1) isolating mobile workers or construction personnel from the captured scene by means of a novel motion detection algorithm and a human classifier and (2) detecting the hardhat in the identified region of interest using an object detection tool coupled with a color-based image classification one. Several experiments were conducted and results highlighted that the proposed framework proved accurate, fast, and robust under different conditions and identified hardhats with high precision and recall. More specifically, the newly developed motion detection algorithm showed an improved accuracy compared to common background subtraction methods; the human classifier performed well and was able to identify several human postures, unlike support vector machine classifiers; and the hardhat detection algorithm achieved high precision and recall simultaneously.
Oxygen Transport and Stem Cell Aggregation in Stirred-Suspension Bioreactor Cultures (2014)

Stirred-suspension bioreactors are a promising modality for large-scale culture of 3D aggregates of pluripotent stem cells and their progeny. Yet, cells within these clusters experience limitations in the transfer of factors and particularly O2 which is characterized by low solubility in aqueous media. Cultured stem cells under different O2 levels may exhibit significantly different proliferation, viability and differentiation potential. Here, a transient diffusion-reaction model was built encompassing the size distribution and ultrastructural characteristics of embryonic stem cell (ESC) aggregates. The model was coupled to experimental data from bioreactor and static cultures for extracting the effective diffusivity and kinetics of consumption of O2 within mouse (mESC) and human ESC (hESC) clusters. Under agitation, mESC aggregates exhibited a higher maximum consumption rate than hESC aggregates. Moreover, the reaction-diffusion model was integrated with a population balance equation (PBE) for the temporal distribution of ESC clusters changing due to aggregation and cell proliferation. Hypoxia was found to be negligible for ESCs with a smaller radius than 100 µm but became appreciable for aggregates larger than 300 µm. The integrated model not only captured the O2 profile both in the bioreactor bulk and inside ESC aggregates but also led to the calculation of the duration that fractions of cells experience a certain range of O2 concentrations. The approach described in this study can be employed for gaining a deeper understanding of the effects of O2 on the physiology of stem cells organized in 3D structures. Such frameworks can be extended to encompass the spatial and temporal availability of nutrients and differentiation factors and facilitate the design and control of relevant bioprocesses for the production of stem cell therapeutics.
HapScope: a software system for automated and visual analysis of functionally annotated haplotypes (2002)

We have developed a software analysis package, HapScope, which includes a comprehensive analysis pipeline and a sophisticated visualization tool for analyzing functionally annotated haplotypes. The HapScope analysis pipeline supports: (i) computational haplotype construction with an expectation-maximization or Bayesian statistical algorithm; (ii) SNP classification by protein coding change, homology to model organisms or putative regulatory regions; and (iii) minimum SNP subset selection by either a Brute Force Algorithm or a Greedy Partition Algorithm. The HapScope viewer displays genomic structure with haplotype information in an integrated environment, providing eight alternative views for assessing genetic and functional correlation. It has a user-friendly interface for: (i) haplotype block visualization; (ii) SNP subset selection; (iii) haplotype consolidation with subset SNP markers; (iv) incorporation of both experimentally determined haplotypes and computational results; and (v) data export for additional analysis. Comparison of haplotypes constructed by the statistical algorithms with those determined experimentally shows variation in haplotype prediction accuracies in genomic regions with different levels of nucleotide diversity. We have applied HapScope in analyzing haplotypes for candidate genes and genomic regions with extensive SNP and genotype data. We envision that the systematic approach of integrating functional genomic analysis with population haplotypes, supported by HapScope, will greatly facilitate current genetic disease research.
Scalable Sequential Spectral Clustering (2016)

In the past decades, Spectral Clustering (SC) has become one of the most effective clustering approaches. Although it has been widely used, one significant drawback of SC is its expensive computation cost. Many efforts have been devoted to accelerating SC algorithms and promising results have been achieved. However, most of the existing algorithms rely on the assumption that data can be stored in the computer memory. When data cannot fit in the memory, these algorithms will suffer severe performance degradations. In order to overcome this issue, we propose a novel sequential SC algorithm for tackling large-scale clustering with limited computational resources, \textit{e.g.}, memory. We begin with investigating an effective way of approximating the graph affinity matrix via leveraging a bipartite graph. Then we choose a smart graph construction and optimization strategy to avoid random access to data. These efforts lead to an efficient SC algorithm whose memory usage is independent of the number of input data points. Extensive experiments carried out on large datasets demonstrate that the proposed sequential SC algorithm is up to a thousand times faster than the state-of-the-arts.
Petrophysical Parameters Estimated From Visual Descriptions of Carbonate Rocks: A Field Classification of Carbonate Pore Space (1983)

Summary The permeability, capillary properties. and m values of carbonate rocks are related to the particle size, amount of interparticle porosity, amount of separate vug porosity, and the presence or absence of touching vugs. Particle size. percent separate vug porosity, and the presence or absence of touching vugs usually can be determined visually. The amount of interparticle porosity is more difficult to determine visually and is done best by subtracting the visual estimate of separate vug porosity from the measure of total porosity obtained from wireline porosity logs or laboratory measurements. In the absence of touching vugs, the permeability, in values, and capillary properties can be estimated if the particle size, percent separate vug porosity, and total porosity are known. No acceptable method has been developed to estimate visually the permeability of touching vugs. A classification of carbonate porosity is proposed based on the data presented. This classification is intended to be used in the field or for routine laboratory description. Interparticle porosity is classified according to particle size and the dense or porous appearance of the interparticle area. Vuggy porosity is classified according to type of interconnection. Separate vugs are connected through the interparticle pore space and classified by percent porosity. Touching vugs are connected to each other and classified by presence or absence. Introduction The role played by the visual description of pore space in carbonate rocks in the field evaluation of a well has changed dramatically over the past 25 to 30 years. The change has been brought about by the development of new and improved logging techniques. The Archie classification, developed in 1952, was the only method at that time to estimate the amount of porosity in uncored wells. The development of porosity wireline tools (neutron, sonic, and density) has provided us with effective ways to measure wellbore porosity. The permeability of a carbonate rock, however, can not be measured directly by wireline tools and it is not directly related to total porosity. Visual descriptions of the pore geometry, therefore, still are needed to estimate permeability. While the Archie classification provides some insight into permeability relationships, new data presented here allow more accurate estimates. In addition, the relationship between pore types and Archie's m value and capillarity can be described. The role that the visual description of pore space can play in the evaluation is to describe factors that cannot be obtained from logging techniques but that are needed together with the logs to calculate saturations and productive capacities of the reservoir rock. This paper describes the basic geologic parameters that control the petrophysical parameters and shows how they are related. JPT P. 629^
Management of Hot Flushes in Breast Cancer Patients (2002)

In breast cancer patients, menopausal symptoms such as hot flushes can be a bothersome problem, with a significant impact on quality of life. Hormone replacement therapy, the mainstay for treatment of these symptoms in healthy women, is traditionally contraindicated. There are, however, several other strategies for the management of flushes in breast cancer patients and these are reviewed in this article.
Excited state reactions in fluorescent proteins (2009)

The green fluorescent protein is a key technology in bioimaging. In this critical review, we consider how its various applications can be tailored from knowledge of the excited state chemistry. The photophysics of the basic chromophore in solution are described in detail, and the dominant radiationless decay mechanism is characterised. The quite different photophysics of wild type GFP are described next. The unique excited state proton transfer reaction observed can be used to model proton transfer processes in proteins. Examples where the proton transfer is blocked, or redirected to occur over a low short barrier H-bond are discussed. Finally the photophysics underlying the new generation of photochemically active fluorescent proteins are discussed (155 references).
Fully Inkjet-Printed Flexible Temperature Sensors Based on Carbon and PEDOT:PSS1 (2016)

Printed organic sensors on plastic substrates are of great interest due to their flexibility and low-cost fabrication. We here present a fully inkjet-printed flexible Wheatstone bridge used for temperature sensing. A carbon nanoparticle ink and a mixture of poly(3,4-ethylenedioxythophene):poly(4-styrene-sulfonate) (PEDOT:PSS) and dimethyl sulfoxide (DMSO) are used as positive (PTC) and negative (NTC) thermal coefficient materials, respectively. Different carbon inks and DMSO concentrations from 0.5 to 40 wt% are evaluated in order to optimize the temperature coefficient of resistance (TCR) and the reliability of the PTC and NTC materials. The single materials are printed on PEN substrates, and subsequently encapsulated. A climate chamber is used to evaluate their reliability. The Wheatstone bridge sensors show good linearity and little hysteresis within a temperature range of 20 °C to 70 °C and exhibit a sensitivity of ∼4 mV/°C at a bias current of 1 mA. We furthermore investigate the reproducibility of the temperature sensor fabrication in order to analyze the potential of industrial applicability of inkjet-printing.
Using Cache-coloring to Mitigate Inter-set Write Variation in Non-volatile Caches (2013)

In recent years, researchers have explored use of non-volatile devices such as STT-RAM (spin torque transfer RAM) for designing on-chip caches, since they provide high density and consume low leakage power. A common limitation of all non-volatile devices is their limited write endurance. Further, since existing cache management policies are write-variation unaware, excessive writes to a few blocks may lead to a quick failure of the whole cache. We propose an architectural technique for wear-leveling of non-volatile last level caches (LLCs). Our technique uses cache-coloring approach which adds a software-controlled mapping layer between groups of physical pages and cache sets. Periodically the mapping is altered to ensure that write-traffic can be spread uniformly to different sets of the cache to achieve wear-leveling. Simulations performed with an x86-64 simulator and SPEC2006 benchmarks show that our technique reduces the worst-case writes to cache blocks and thus improves the cache lifetime by 4.07X.
On the Generation of Noise by Turbulent Jets (1959)

Abstract : Elementary methods are used to provide a fundamental understanding of the salient features of jet noise. Simple reasoning yields information about the total noise power and spectral shape which are in encouraging agreement with experiment. The possibilities of remedying certain deficiencies are discussed, and the failure of existing methods is illustrated by reference to rocket noise.
Periodic K-Alpha Sleep EEG Activity and Periodic Limb Movements During Sleep: Comparisons of Clinical Features and Sleep Parameters (1996)

The K-alpha sleep electroencephalographic (EEG) phenomenon is characterized by periodic (approximately 20-40 seconds) K-complexes, immediately followed by alpha-EEG activity (7.5-11 Hz) of 0.5- to 5.0-second duration. A group of 14 subjects with the periodic K-alpha anomaly was found to have a similar distribution pattern of interevent intervals as compared with previously published data for sleep-related periodic limb movements during sleep (PLMS). Sleep parameters and somatic symptoms of 30 patients with K-alpha were compared with 30 patients with PLMS. The periodic K-alpha group was predominantly female, younger, exhibiting more slow-wave sleep, gastrointestinal symptoms and muscular complaints and fewer movement arousals on overnight polysomnography. The K-alpha group presented uniformly with complaints of unrefreshing sleep, often associated with fibromyalgia and chronic fatigue syndrome. The PLMS group was predominantly male, showed greater sleep disruption and presented with a variety of sleep-related symptoms.

Während des Gynäkologen-Kongresses 1966 in Hannover konnte ich erstmalig über die Blockade des Nervus hypogastricus zur Bekämpfung des Wehenschmerzes berichten. Unter dem Titel „Geburtserleichterung durch paracervicale Leitungsanaesthesie“ teilte ich damals unsere Behandlungsergebnisse von 400 Fällen mit.
Neonatal Herpes Simplex Virus Infection Introduced by Fetal-Monitor Scalp Electrodes (1980)

An infant was severely infected with herpes simplex virus as a result of fetal monitoring with scalp electrodes on the buttocks. The first vesicles appeared at the site where the electrodes had been placed and, by day 9 after birth, additional lesions covered the entire perineum and lower extremities. The child developed acute meningoencephalitis and pneumatosis intestinalis. Herpes simplex virus was isolated from cultures of skin vesicle fluid, cornea, saliva, blood, and spinal fluid. The infection resolved after treatment with adenosine arabinoside, administered intravenously for 11 days and applied topically for another 15 days. A follow-up examination when the child was 2 years old disclosed no physical or neurologic abnormalities. This case illustrates the risk of introducing herpes simplex infection by internal fetal monitoring.

Exercise induces autophagy in peripheral tissues and in the brain (2012)

We recently identified physical exercise as a newly defined inducer of autophagy in vivo. Exercise induced autophagy in multiple organs involved in metabolic regulation, such as muscle, liver, pancreas and adipose tissue. To study the physiological role of exercise-induced autophagy, we generated mice with a knock-in nonphosphorylatable mutation in BCL2 (Thr69Ala, Ser70Ala and Ser84Ala) (BCL2 AAA) that are defective in exercise- and starvation-induced autophagy but not in basal autophagy. We found that BCL2 AAA mice could not run on a treadmill as long as wild-type mice, and did not undergo exercise-mediated increases in skeletal glucose muscle uptake. Unlike wild-type mice, the BCL2 AAA mice failed to reverse high-fat diet-induced glucose intolerance after 8 weeks of exercise training, possibly due to defects in signaling pathways that regulate muscle glucose uptake and metabolism during exercise. Together, these findings suggested a hitherto unknown important role of autophagy in mediating exercise-induced metabolic benefits. In the present addendum, we show that treadmill exercise also induces autophagy in the cerebral cortex of adult mice. This observation raises the intriguing question of whether autophagy may in part mediate the beneficial effects of exercise in neurodegeneration, adult neurogenesis and improved cognitive function.
