Magnetic Properties of Ultrathin Laminated Co/Cu Films Prepared by Electrodeposition (2002)

The magnetic properties of a series of electrodeposited multilayers have been examined as a function of the cobalt layer thickness. The multilayers were grown on Si(100) covered with a highly textured Cu(100) seed layer. Films with a cobalt layer thickness less than monolayer equivalents (ML) exhibit superparamagnetic behavior due to the finite size of the cobalt islands comprising the discontinuous multilayer structure. In contrast, in films with the lateral length scale becomes large enough to stabilize ferromagnetism and the giant magnetoresistance effect is observed. The influence of magnetocrystalline anisotropy is not apparent until The coercivity increases between 1.6 and 9 ML, reflecting the combined influence of the magnetocrystalline anisotropy and surface roughness. © 2002 The Electrochemical Society.

Classification and physiopathological data of superficial "angiomas" (1999)

This article emphasizes the progress achieved in the classification of superficial angiomas. The grouping of physicians in multidisciplinary groups and the analysis of advances in diagnosis, treatment, biology and genetics within an international society (the ISSVA) have resulted in better management of these orphan pathologies. Each type of angioma (vascular tumours such as hemangioma or vascular malformations) is described with its specificities and particular therapeutic approach.
The LIM protein RBTN2 and the basic helix-loop-helix protein TAL1 are present in a complex in erythroid cells. (1994)

Chromosomal translocations in T-cell acute leukemias can activate genes encoding putative transcription factors such as the LIM proteins RBTN1 and RBTN2 and the DNA-binding basic helix-loop-helix transcription factor TAL1 associated with T-cell acute lymphocytic leukemia. While not expressed in normal T cells, RBTN2 and TAL1 are coexpressed in erythroid cells and are both important for erythroid differentiation. We demonstrate, using anti-RBTN2 and anti-TAL1 antisera, that the LIM protein RBTN2 is not phosphorylated and is complexed with the TAL1 phosphoprotein in the nucleus of erythroid cells. A complex containing both RBTN1 and TAL1 also occurs in a T-cell acute leukemia cell line. Since both RBTN2 and TAL1 are crucial for normal erythropoiesis, these data have important implications for transcription networks therein. Further, since both proteins can be involved in leukemogenesis, these data provide a direct link between proteins activated by chromosomal translocations in T-cell acute leukemia.
Association of Plasma Matrix Metalloproteinase and Tissue Inhibitors of Matrix Metalloproteinase Levels With Adverse Treatment Outcomes Among Patients With Pulmonary Tuberculosis (2020)

Baseline plasma MMP and TIMP levels may be correlates of risk and prognostic biomarkers for treatment failure, relapse, and death in individuals with PTB and merit further evaluation as predictive biomarkers for stratification of patients to shortened or intensified treatment regimens.
A Device for Performing Automated Balloon Catheter Inflation Ischemia Studies (2014)

Coronary collateral growth (arteriogenesis) is a physiological adaptive response to transient and repetitive occlusion of major coronary arteries in which small arterioles (native collaterals) with minimal to no blood flow remodel into larger conduit arteries capable of supplying adequate perfusion to tissue distal to the site of occlusion. The ability to reliably and reproducibly mimic transient, repetitive coronary artery occlusion (ischemia) in animal models is critical to the development of therapies to restore coronary collateral development in type II diabetes and the metabolic syndrome. Current animal models for repetitive coronary artery occlusion implement a pneumatic occluder (balloon) that is secured onto the surface of the heart with the suture, which is inflated manually, via a catheter connected to syringe, to effect occlusion of the left anterior descending coronary artery (LAD). This method, although effective, presents complications in terms of reproducibility and practicality. To address these limitations, we have designed a device for automated, transient inflation of balloon catheters in coronary artery occlusion models. This device allows repeated, consistent inflation (to either specified pressure or volume) and the capability for implementing very complex, month-long protocols. This system has significantly increased the reproducibility of coronary collateral growth studies in our laboratory, resulting in a significant decrease in the numbers of animals needed to complete each study while relieving laboratory personnel from the burden of extra working hours and enabling us to continue studies over periods when we previously could not. In this paper, we present all details necessary for construction and operation of the inflator. In addition, all of the components for this device are commercially available and economical (Table S1). It is our hope that the adoption of automated balloon catheter inflation protocols will improve the experimental reliability of transient ischemia studies at many research institutions.
A tetraamido isophthaloyl-based macrocyclic calcium chloride and strontium chloride tritopic receptor (2012)

Several new macrocyclic di-, tetra-, hexa- and octa-amido macrocycles have been synthesized and their complexation properties are reported with Group 1 and 2 metal chlorides, and also with tetrabutylammonium tetrafluoroborate, phosphorus hexafluoride and halide salts.
Realistic and Repeatable Emulation of Energy Harvesting Environments (2017)

Harvesting energy from the environment makes it possible to deploy tiny sensors for long periods of time, with little or no required maintenance; however, this free energy makes testing and experimentation difficult. Environmental energy sources vary widely and are often difficult both to predict and to reproduce in the lab during testing. These variations are also behavior dependent—a factor that leaves application engineers unable to make even simple comparisons between algorithms or hardware configurations, using traditional testing approaches. In this article, we describe the design and evaluation of Ekho, an emulator capable of recording energy harvesting conditions and accurately recreating those conditions in the lab. This makes it possible to conduct realistic and repeatable experiments involving energy harvesting devices. Ekho is a general-purpose, mobile tool that supports a wide range of harvesting technologies. We demonstrate, using a working prototype, that Ekho is capable of reproducing solar, Radio Frequency (RF), and kinetic energy harvesting environments accurately and consistently. Our results show that Ekho can recreate harvesting-dependent program behaviors by emulating energy harvesting conditions accurately to within 77.4μA for solar and 15.0μA for kinetic environments, and can emulate RF energy harvesting conditions consistently.
Low PAPR Waveform Design for OFDM Systems Based on Convolutional Autoencoder (2020)

This paper introduces the architecture of a convolutional autoencoder (CAE) for the task of peak-to-average power ratio (PAPR) reduction and waveform design, for orthogonal frequency division multiplexing (OFDM) systems. The proposed architecture integrates a PAPR reduction block and a non-linear high power amplifier (HPA) model. We apply gradual loss learning for multi-objective optimization. We analyse the model' performance by examining the bit error rate (BER), the PAPR and the spectral response, and comparing them with common PAPR reduction algorithms.
Joint development of disparity tuning and vergence control (2011)

Behavior and sensory perception are mutually dependent. Sensory perception drives behavior, but behavior can also influence the development of sensory perception, by altering the statistics of the sensory input. Thus, there is a “chicken-and-egg” problem as to which arises first. We propose here a solution to this problem in the context of the neural processing of binocular disparity and the behavioral control of binocular vergence to maintain fixation. We show that it is possible for both the neural processing and the control policy to develop simultaneously. In particular, we assume that the neural processing develops through learning a sparse complex-cell representation of the input, and that the control policy simultaneously develops through reinforcement learning to maximize the activity in this complex cell representation. These processes are coupled. The control policy determines the statistics of the input, which determines the sparse coding that develops, which in turn determines the reward maximized by the control policy. Our experiments show that both disparity selective binocular receptive fields and a successful binocular fixation policy develop. Our results underline the importance of behavior, as we show that on the same input but in the absence of learned behavior, much fewer disparity selective binocular receptive fields develop.
Effects of Caffeine, Halothane, and 4-Chloro-m -cresol on Skeletal Muscle Lactate and Pyruvate in Malignant Hyperthermia–susceptible and Normal Swine as Assessed by Microdialysis (2005)

The authors data demonstrate that the in vivo muscle microdialysis of the porcine L/P system reveals distinct differences between MH-susceptible and MH-normal muscle, especially in response to highly specific RyR1 agonists such as 4CmC. The microdialysis L/P technique seems to have an MH diagnostic potential in the clinical setting.
Dark to Bright Mode Conversion on Dipolar Nanoantennas: A Symmetry-Breaking Approach (2014)

The excitation of plasmonic dark modes via a radiative channel is a phenomenon strongly hindered in the subwavelength regime. Recently, for achieving this purpose it has been proposed to exploit near-field interactions between radiating (bright) modes and lossless dark modes. However, this approach unveils challenging difficulties related to the excitation of dark modes through the near-field coupling with a bright mode. Here, it is experimentally and numerically shown how symmetry breaking applied to a nanoantenna dimer can conversely induce the excitation of plasmonic resonances, which play a key role for the dark modes’ activation in more complex nanoassemblies. On the basis of this study, a T-shaped nanoantenna trimer has been introduced as an elemental unit for the energy transfer between bright and dark modes in plasmonic nanostructures. Finally, we implemented an analytical perturbative model to further investigate the plasmonic hybridization of subwavelength systems.
Combined X-ray and neutron powder refinement of the magnetite (Fe3O4) structure below the Verwey transition (2002)

YNi2B2C and and other rare earth (R) compounds of the type RNi2B2C are of large interest due to their superconducting and magnetic ordering properties. These compounds have tetragonal structure which is composed by stacking of RC and BNi2B layers along c-axis. Reaction products from a melt sample series of YNi2-xNi2-xC (x = 0.2, 0.35 and 0.5) were investigated by X-ray single-crystal and TEM diffraction to verify that a change of the chemical composition and a variation of the layer arrangement had to lead to new structures. Apart from YNi2B2C and the known YNiBC and Y3Ni4B4C3 three metastable compounds could be analysed: Y5Ni6B6C5 and Y5Ni8B8C5 -bodycentred tetragonal structures with predicted layer sequences, Y5Ni9B9C5primitive tetragonal modulated structure.
Episomal Viral DNA in a Herpesvirus saimiri -Transformed Lymphoid Cell Line (1977)

The lymphoid cell line #1670 has been derived from the infiltrated spleen of a tumor-bearing marmoset monkey infected with Herpesvirus saimiri. The cells contain both types of H. saimiri DNA, unique light (L-) DNA (36% cytosine plus guanine) and repetitive heavy (H-) DNA (71% cytosine plus guanine), without producing infectious virus. Viral DNA was found to persist in these cells as nonintegrated circular DNA molecules. Closed circular superhelical viral DNA molecules were isolated by three subsequent centrifugation steps: (i) isopycnic centrifugation in CsCl, (ii) sedimentation through glycerol gradients, and (iii) equilibrium centrifugation in CsCl-ethidium bromide. The isolated circles had a molecular weight of 131.5 +/- 3.6 x 10(6). This is significantly higher than the molecular weight of linear DNA molecules isolated from purified H. saimiri virions (about 100 x 10(6)). Partial denaturation mapping of circular molecules from #1670 lymphoid cells showed uniform arrangement of H- and L-DNA sequences in all circles. All denatured molecules contained two L-DNA regions (molecular weights of 54.0 +/- 1.8 x 10(6) and 31.5 +/- 1.3 x 10(6)) and two H-DNA regions (molecular weight of 25.6 +/- 1.9 x 10(6) and 20.0 +/- 0.8 x 10(6)) of constant length. Maps of both L-regions suggested that the sequences of the shorter L-DNA region were a subset of those of the longer region. The sequences of both L-regions had the same orientation. Circular molecules from H. saimiri-transformed lymphoid cell line #1670 appeared to represent defective genomes, containing only 75% of the genetic information present in L-DNA of H. saimiri virions.
Properties of the B-Si-N ceramic thin films by plasma-CVD. (1988)

B-Si-N composite thin films were prepared by the plasma enhanced chemical vapour deposition method of inductive couple. The purpose of this paper is a micro structual control of boron nitride film, so we added Si in this film. The source gases used were B2H6, SiH4 and N2. The rf power, tempareture of substrate and gas pressure during depositions were 20 W, 300°C and 2 × 10-2 Torr, respectively. The physical, mechanical and optical properties of the films were investigated by several methods to clarify the effect of Si content. The following results were obtained;1) The prepared B-Si-N thin films were composed of two phases of BN and SiNx.2) The hardness (Hv) of the thin films gradually decreased from 6, 000 to 3, 000 as Si content increaced from O to 48 at%.3) The fracture toughness of the thin film improved dramatically when Si content exceeded 10 at%.4) The transmission and refractive index within a range between 700 and 2, 000 nm in wavelength, were 95-99% and 1.4-1.9 respectively depending on Si content.
Cellular Pathways Leading to Neuronal Dysfunction and Degeneration (2007)

There is no cure for devastating neurodegenerative disorders such as Alzheimer's, Parkinson's, Huntington's diseases or amyotrophic lateral sclerosis, which cause longterm suffering and ultimately death. Slowly progressing neurodegenerative diseases affect the lives of many thousands of patients and their families. These disorders are characterized by pathological changes in disease-specific areas of the brain. In each disease, these pathological processes lead to dysfunction and degeneration in distinct subsets of neurons. Research on neurodegenerative disorders has revealed a complex picture of cellular pathology involving abnormalities in biochemical processes, gene regulation, responses to external stimuli, etc. However, despite the differences in the clinical manifestations and selective neuronal vulnerability, on cellular and molecular levels the underlying pathological processes appear similar across different diseases, suggesting common pathways of neurodegeneration. Elucidation of the precise neurodegenerative mechanism(s) is essential for development of effective and safe therapy for these lethal human disorders.
Pipelined QR decomposition based multi-channel least square lattice adaptive filter architectures (2003)

QR decomposition based multi-channel least square lattice (QRD-MLSL) algorithm possesses a good numerical property and regularity which are attractive for VLSI implementation. However, due to the presence of a local recursive loop in its implementation, the algorithm's speed is limited to the computation time of each computation cell. In this paper, a novel approach for pipelining the QRD-MLSL adaptive filtering algorithm is developed. The proposed architecture is pipelined at fine-grain level, thus it can be operated at arbitrarily high speed. Furthermore, it provides an exact least square solution, so there is no performance degradation. Computer simulations are presented to demonstrate the functionality of the proposed pipelining methodology.
Scalable, effective, and rapid decontamination of SARS-CoV-2 contaminated N95 respirators using germicidal ultra-violet C (UVC) irradiation device (2020)

A scalable germicidal UVC device to deliver tailored UVC dose for rapid decontamination of SARS-CoV-2 was developed. UVC germicidal irradiation of N95 snippets inoculated with SARS-CoV-2 for 120s per side resulted in 100% (3.5 log in total) reduction of virus. These data support the reuse of N95 particle-filtrate apparatus upon irradiation with UVC and supports use of UVC-based decontamination of SARS-CoV-2 virus during the COVID19 pandemic.
A 40–170 MHz PLL-Based PWM Driver Using 2-/3-/5-Level Class-D PA in 130 nm CMOS (2016)

A high-speed driver that provides a pulsewidth modulated output while using a class-D Power Amplifier (PA) is described. A PLL-based architecture is employed, which eliminates the requirement for a precise ramp or triangular signal generator, and a high-speed comparator, which are typically used in pulsewidth modulation (PWM) generation. Multilevel signaling is proposed to enhance back-off as well as peak efficiency, which is critical for signals with high peak-to-average power ratios (PAPRs). A differential folded PWM scheme is introduced to achieve highly linear operation. 3-level operation is achieved without the requirement for additional supply source or sink paths, while 5-level operation is achieved with an additional supply source/sink path compared with the 2-level operation. The PWM driver has been implemented in a 130 nm CMOS process and can operate with a switching frequency of 40-170 MHz. For the 2-/3-/5-level PA operation, with a 500 kHz sinusoidal input and 60 MHz switching frequency, the measured THD is -61/-62/-53 dB and the corresponding efficiency is 71%/83%/86% with 175/200/220 mW output power level, respectively. Performance has also been verified for 2-/3-level PA with a high PAPR signal with 500 kHz bandwidth. While intended as a general-purpose amplifier, the approach is well-suited for applications such as power-line communications.
Eco-hydromorphic Classification for Understanding Stream Macroinvertebrate Biodiversity in Brunei Darussalam, Northern Borneo. (2016)

Kate Baker, Michael A. Chadwick, and Zohrah Haji Sulaiman (2016) Linking ecology with river geomor- phology and hydrology (geomorphic and hydraulic template) plays an important role in the study of macroinver- tebrate biodiversity. This understanding and knowledge is crucial in implementing sensible conservation management for ecosystem health monitoring. However, most macroinvertebrate research has been conducted in temperate ecosystems. This study examines the eco-hydrogeomorphology and macroinvertebrate biodiversity of two remote tropical streams in northern Borneo (Bukit Pagon catchment, Brunei Darussalam’s highest mountain - 1850 m) using temperate classification models, more specifically, biotopes. Fast flowing biotopes were defined as bedrock runs and cobble riffles whilst the slow flowing biotopes were deposition pools. Macroinvertebrate size structure associated with biotopes, which can influence overall ecological processes, was also investigated. Forty-three macroinvertebrate taxa were recorded during the study; biodiversity was similar between the study streams. There were differences among biotopes with the lowest diversity occurring in fast flowing biotopes (p = 0.05*). Community structure also varied among the biotopes. Cluster analysis of macroinvertebrate abundance revealed an 0.8 dissimilarity between the fast and slow biotopes. Several taxa were found in multiple biotopes, which is likely linked to the occurrence of moss and leaf litter. Macroinvertebrate size structure distribution between the fast and slow biotopes was statistically different. Our findings suggest biotopes may be an appropriate scale to investigate macroinvertebrate biodiversity in tropical streams. Specifically, we found that biotopes had different macroinvertebrate communities and richness. Further research is required to understand the importance of habitat parameters that are not directly related to flow velocities such as moss. These habitats are important as places of refuge, allowing colonisation that would otherwise be inhospitable during flood periods.

The Pleiotropic Effects of Statins – From Coronary Artery Disease and Stroke to Atrial Fibrillation and Ventricular Tachyarrhythmia (2018)

Statins, 3-hydroxy-methylglutaryl coenzyme A reductase inhibitors, have been used for decades for the prevention of coronary artery disease and stroke. They act primarily by lowering serum cholesterol through the inhibition of cholesterol synthesis in the liver, which results in the upregulation of low-density lipoprotein receptors in the liver. This results in the removal of low-density lipoproteincholesterol. Studies have suggested that statins may demonstrate additional effects that are independent of their effects on low-density lipoprotein-cholesterol. These have been termed “pleiotropic” effects. Pleiotropic effects may be due to the inhibition of isoprenoid intermediates by statins. Isoprenoid inhibition has effects on the small guanosine triphosphate binding proteins Rac and Rho which in turn effects nicotinamide adenine dinucleotide phosphate oxidases. Therefore, there are changes in endothelial nitric oxide synthase expression, atherosclerotic plaque stability, pro-inflammatory cytokines and reactive oxygen species production, platelet reactivity, and cardiac fibrosis and hypetrophy development. Recently, statins have been compared to the ezetimibe and the recently published outcomes data on the proprotein convertase subtilisin kexin type 9 inhibitors has allowed for a reexamination of statin pleiotropy. As a result of these diverse effects, it has been suggested that statins also have anti-arrhythmic effects. This review focuses on the mechanisms of statin pleiotropy and discusses evidence from the statin clinical trials as well as examining the possible anti-arrhythmic effects atrial fibrillation and ventricular tachyarrhythmias.
