This paper presented the average BLER performance using the combination of low-rate turbo code and codebook based transmit diversity associated with the IDDCE for DFT-precoded OFDMA. Computer simulation results showed that the average BLER of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> for R = 1/15 (1/9) is achieved at the average received SNR of approximately -9.8 (- 8.2) and -11.8 (-10.4) dB for the N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Tx</sub> = 2- or 4-antenna codebook transmit diversity, respectively, with N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Rx</sub> = 4-antenna receiver diversity using the IDDCE. In conclusion, we confirmed the effectiveness of the combination of low-rate turbo code and codebook based transmit diversity using the IDDCE for achieving the very low required average received SNR satisfying the target average BLER.

A collection of the novel coronavirus (COVID-19) detection assays, issues, and challenges (2021)

The global pandemic of COVID-19 has rapidly increased the number of infected cases as well as asymptomatic individuals in many, if not all the societies around the world. This issue increases the demand for accurate and rapid detection of SARS-CoV-2. While accurate and rapid detection is critical for diagnosing SARS-CoV-2, the appropriate course of treatment must be chosen to help patients and prevent its further spread. Testing platform accuracy with high sensitivity and specificity for SARS-CoV-2 is equally important for clinical, regional, and global arenas to mitigate secondary transmission rounds. The objective of this article is to compare the current detection technology and introduce the most accurate and rapid ones that are suitable for pandemic circumstances. Hence, the importance of rapid detection in societies is discussed initially. Following this, the current technology for rapid detection of SARS-CoV-2 is explained and classified into three different categories: nucleic acid-based, protein-based, and point of care (PoC) detection testing. Then, the current issues for diagnostic procedures in laboratories are discussed. Finally, the role of new technologies in countering COVID-19 is also introduced to assist researchers in the development of accurate and timely detection of coronaviruses. As coronavirus continues to affect human lives in a detrimental manner, the development of rapid and accurate virus detection methods could promote COVID-19 diagnosis accessible to both individuals and the mass population at patient care. In this regard, rRT-PCR and multiplex RT-PCR detection techniques hold promise.
Synthesis and SAR of 1-Hydroxy-1H-benzo[d]imidazol-2(3H)-ones as Inhibitors of d-Amino Acid Oxidase (2012)

A series of 1-hydroxy-1H-benzo[d]imidazol-2(3H)-ones were synthesized and evaluated for their ability to inhibit human and porcine forms of D-amino acid oxidase (DAAO). Inhibitory potency is largely dependent on the size and position of substituents on the benzene ring with IC(50) values of the compounds ranging from 70 nM to greater than 100 µM. Structure-activity relationships of this new class of DAAO inhibitors will be presented in detail along with comparisons to previously published SAR data from other classes of DAAO inhibitors. Some of these compounds were given to mice orally together with D-serine to assess their effects on plasma D-serine pharmacokinetics.

Draft Genome Sequence of Saccharomyces cerevisiae NAM34-4C, a Lactic Acid-Assimilating Industrial Yeast Strain (2014)

We determined the genome sequence of industrial Saccharomyces cerevisiae strain NAM34-4C, which would be useful for bioethanol production. The approximately 11.5-Mb draft genome sequence of NAM34-4C will provide remarkable insights into metabolic engineering for effective production of bioethanol from biomass.
Growth and Characterization of Nitrogen‐Polar AlGaN/AlN Heterostructure for High‐Electron‐Mobility Transistor (2020)

A nitrogen‐polar (N‐polar) AlGaN/AlN high‐electron‐mobility transistor (HEMT) is proposed, and the generation of a 2D electron gas (2DEG) is simulated. The band diagram of N‐polar (Al)GaN/AlN shows the generation of the 2DEG, whereas that of the conventional metal‐polar (Al)GaN/AlN structure shows the generation of a 2D hole gas. Furthermore, the concentration of the 2DEG is considerably high even when the (Al)GaN layer is as thin as a few nanometers. N‐polar AlGaN/AlN is grown on sapphire substrates with a misorientation angle of 2°; furthermore, atomic force microscope measurements in a range of 5 × 5 μm 2 demonstrate that the root‐mean‐square value obtained from atomic force microscopy of N‐polar AlGaN is approximately 0.7 nm. N‐polar AlGaN layers with a thickness of approximately 40–60 nm with more than 50% Al content are almost coherently grown on the N‐polar AlN layer with a thickness of approximately 400 nm.

Parametric sideband generation in CMOS-compatible oscillators from visible to telecom wavelengths (2021)

We present an approach for generating widely separated first sidebands based solely on the four-wave-mixing process in optical parametric oscillators built on complementary metal–oxide–semiconductor-compatible photonic chips. Using higher-order transverse modes to perform dispersion engineering, we obtain zero-group-velocity dispersion near 796 nm. By pumping the chip in the normal dispersion region, at 795.6 nm, we generate a signal field in the visible band (at 546.2 nm) and the corresponding idler field in the telecom band (at 1465.3 nm), corresponding to a frequency span of approximately 346 THz. We show that the spectral position of signal and idler can be tailored by exploiting a delicate balance between second- and fourth-order dispersion terms. Furthermore, we explicitly demonstrate a change in the parametric oscillation dynamics when moving the pump field from the anomalous to normal dispersion, where the chip ceases producing multiple sidebands adjacent to the pump field and generates widely separated single sidebands. This provides a chip-scale platform for generating single-sideband fields separated by more than one octave, covering the visible and telecom spectral regions.
An Experimental Study on the Motion of Floating Bodies Arranged in Series for Wave Power Generation (2017)

This paper considered the optimal arrangement on the assumption that multiple power generation systems are used in a row ahead of the realization of the wave power generation system using the DE (dielectric elastomer) which is expected to be popularized in the future. A power generation system using DEs was studied as a moored floating body, and tank tests were conducted. There are few studies on the influence of multiple moored floating bodies on each other. Those studies clarified the fluctuation, energy absorption efficiency, tension mooring force and quietness characteristics produced from differences in the arrangement of the floating bodies within the floating body group and so on utilizing the principle of double oscillating water columns. The purpose of this paper is to clarify the influence of floating body intervals and number of floating bodies on floating motion and mooring tension when a plurality of floating bodies are moored in a row perpendicular to the advancing wave direction. We also discuss the conditions of the large power generation system in actual sea areas using the DEs.
LAT1 Is a Central Transporter of Essential Amino Acids in Human Umbilical Vein Endothelial Cells (2014)

Endothelial cell proliferation supporting angiogenesis requires sufficient nutrient supply because of facilitated intracellular metabolism. However, little is known about the mechanism for the promotion of nutrient incorporation in proliferating endothelial cells. Here we show that L-type amino acid transporter 1 (LAT1) is a major transporter of essential amino acids in human umbilical vein endothelial cells (HUVECs). Growing HUVECs express a certain level of LAT1. A LAT1-specific inhibitor suppressed leucine uptake, cell proliferation, and tube formation of HUVECs. Therefore, LAT1 acts to support effective uptake of amino acids, which is critical for the optimal function of HUVECs for angiogenesis.
Ionic Transport and Charge Distribution in Miniaturized Electrochemical Energy Storage Devices by Modeling Investigation (2022)

Ions are at the core of the mechanism involved in electrochemical energy storage. However, it remains difficult to physically measure the local ionic transport inside working devices. Limiting factors in the local transport in Miniaturized Electrochemical Energy Storage (MEES), especially in 3D Li-ion microbatteries, are investigated using finite element modeling with COMSOL Multiphysics®. This work aims to lay the basements for establishing a relationship between the main limiting factors of Li-ion microbatteries, to provide the critical points for designing the efficient microstructures. Contrary to what was reported in the literature, we demonstrate that the electronic conductivity of the electrodes does not play such a significant role in limiting the performance of a Li-ion microbattery. We show that the main limiting factor is the ionic diffusion inside the electrode, and also the geometry and charge applied to the battery (Crate) which are closely related to ionic diffusion in the electrode.
RIN: A Declarative Specification for Interactive Narratives over Rich Media (2012)

Rich media technologies like streaming video, gigapixel panoramas, and terapixel maps are becoming broadly available on the Internet. Although rich media offer wonderful opportunities for creating experiences that have strong interactive and narrative elements, the ways in which users experience these media are widely disparate, involving a plethora of similar-yet-different web sites and mobile applications, each with its own proprietary rendering logic, data formats, and back-end services. In this paper we introduce RIN —a declarative specification for orchestrating interactive, cinematic narratives that thread through an extensible set of rich media experiences. RIN’s XML (and JSON equivalent) markup makes it straightforward to represent complex, cinematic fly-throughs that fluidly compose diverse media technologies, including gigapixel panoramas, terapixel online maps, traditional paginated documents, and data visualizations, choreographed together with audio, text, and video. RIN introduces a concise representation of the logical state of an experience, called Small State, and the specification of the evolution of this state over time, called an Experience Stream. These abstractions along with others introduced in this paper enable a concise, declarative specification for a wide range of rich media experiences. We believe RIN can serve as the foundation for the next generation of standards-based rich media on the Internet, enabling a variety of new and compelling scenarios.
Ferroelectric Nematic Monolayer (2003)

Ferroelectricity is desirable for realizing fast-response liquid crystal devices. Existing ferroelectric liquid crystals are improper with the spontaneous polarization Ps being indirectly induced by the broken centrosymmetry of molecular arrangement. We found that Langmuir monolayers of certain dialkylated nematic compound exhibit a laterally polarized two-dimensional ferroelectric nematic. The Ps is comparable to that of chiral smectic liquid crystals, and shows a fast linear electro-optic switching with a microsecond response. Estimates of electrostatic energy suggest that the ferroelectricity may be driven by the direct dipolar interactions.
Continuous arterial spin labeling (CASL) in the monkey brain at high magnetic field using a three-coil approach (2005)

CASL experiments in the monkey brain were performed at 4.7 T and 7 T using a separate labeling coil. Increased sensitivity and SNR were achieved by a custom-made three-coil setup and high magnetic field with its increased T1. We report the development and optimization of the setup and first experiments in the monkey (macaca mulatta). Parameters for continuous labeling (label power, label duration, post label delay) were optimized to measure gray matter rCBF and fCBF changes, reporting excellent multi-slice coverage at high resolution of 0.75  1 mm in-plane.
Unsupervised Audio Segmentation using Extended Baum-Welch Transformations (2007)

Audio segmentation has applications in a variety of contexts, such as audio information retrieval, automatic sound analysis, and as a pre-processing step in speech recognition. Extended Baum-Welch (EBW) transformations are most commonly used as a discriminative technique for estimating parameters of Gaussian mixtures. In this paper, we derive an unsupervised audio segmentation approach using these transformations. We find that our algorithm outperforms both the Bayesian information criterion (BIC) and cumulative sum (CUSUM) segmentation methods. In particular, our EBW segmentation algorithm provides improvements over the baseline approaches in detecting landmarks of short duration and minimizing landmark oversegmentation. In addition, we show that the EBW approach provides faster computation compared to the baseline methods.

Energy-efficiency in decentralized wireless networks: A game-theoretic approach inspired by evolutionary biology (2014)

Energy efficiency is gaining importance in wireless communication networks which have nodes with limited energy supply and signal processing capabilities. We present a numerical study of cooperative communication scenarios based on simple local rules. This is in contrast to most of the approaches in the literature which enforce cooperation by using complex algorithms and require strategic complexity of the network nodes. The approach is motivated by recent results in evolutionary biology which suggest that, if certain mechanism is at work, cooperation can be favored by natural selection, i. e. even selfish actions of the individual nodes can lead to emergence of cooperative behavior in the network. The results of the simulations in the context of wireless communication networks verify these observations and indicate that uncomplicated local rules, followed by simple fitness evaluation, can generate network behavior which yields global energy efficiency.

Rec dependence of mu transposition from P22-transduced fragments (1987)

Derivatives of bacteriophage Mu carrying a lac operon and a selectable drug resistance element (Mu d phages) are frequently used tools of bacterial genetics. Mu d prophages used in this way can be treated as transposons, in that the inserted material can be transduced from one strain to another by general transducing phages, such as P1 and P22. When a Mu d prophage is transduced into a new recipient by P1 or P22, the Mu d element can transpose from the transduced fragment into the bacterial chromosome. Transposition of the Mu d element from a P22-transduced fragment shows several striking differences from transposition of a Mu d genome injected by a Mu virion. First, the frequency of transposition from a transduced fragment is greatly enhanced by a P22 helper genome. Second, transposition requires the host recA, B, and C functions. Transposition of Mu following injection by a Mu virion is rec independent. While the basis of these observations is not understood, we suggest that the Mu X protein, a 65-kilodalton protein injected by a Mu virion and required for Mu transposition, may not be packaged by P22. We suggest that the effects seen reflect the behavior of a Mu genome in the absence of the X protein.

Belatacept Does Not Inhibit Follicular T Cell-Dependent B-Cell Differentiation in Kidney Transplantation (2017)

Humoral alloreactivity has been recognized as a common cause of kidney transplant dysfunction. B-cell activation, differentiation, and antibody production are dependent on IL-21<sup>+</sup>CXCR5<sup>+</sup>follicular T-helper (Tfh) cells. Here, we studied whether belatacept, an inhibitor of the costimulatory CD28-CD80/86-pathway, interrupts the crosstalk between Tfh- and B-cells more efficiently than the calcineurin inhibitor tacrolimus. The suppressive effects of belatacept and tacrolimus on donor antigen-driven Tfh-B-cell interaction were functionally studied in peripheral blood mononuclear cells from 40 kidney transplant patients randomized to a belatacept- or tacrolimus-based immunosuppressive regimen. No significant differences in uncultured cells or donor antigen-stimulated cells were found between belatacept- and tacrolimus-treated patients in the CXCR5<sup>+</sup>Tfh cell generation and activation (upregulation of PD-1). Belatacept and tacrolimus <i>in vitro</i> minimally inhibited Tfh-cell generation (by ~6-7%) and partially prevented Tfh-cell activation (by ~30-50%). The proportion of IL-21<sup>+</sup>-activated Tfh-cells was partially decreased by <i>in vitro</i> addition of belatacept or tacrolimus (by ~60%). Baseline expressions and proportions of activated CD86<sup>+</sup> B-cells, plasmablasts, and transitional B-cells after donor antigen stimulation did not differ between belatacept- and tacrolimus-treated patients. Donor antigen-driven CD86 upregulation on memory B-cells was not fully prevented by adding belatacept <i>in vitro</i> (~35%), even in supratherapeutic doses. In contrast to tacrolimus, belatacept failed to inhibit donor antigen-driven plasmablast formation (~50% inhibition vs. no inhibition, respectively, <i>p</i> < 0.0001). In summary, donor antigen-driven Tfh-B-cell crosstalk is similar in cells obtained from belatacept- and tacrolimus-treated patients. Belatacept is, however, less potent <i>in vitro</i> than tacrolimus in inhibiting Tfh-cell-dependent plasmablast formation.
Pro-A-type and N-terminal pro-B-type natriuretic peptides in different thyroid function states (2005)

Natriuretic peptide levels are altered in different thyroid states with a more pronounced effect in hyperthyroidism than in hypothyroidism. Hyperthyroidism should be considered in patients presenting with unclear symptoms and mildly elevated natriuretic peptide levels, as overt hyperthyroidism results in increased serum A- and B-type natriurectic peptide levels, typically seen in mild heart failure.
Similarity Search for Efficient Active Learning and Search of Rare Concepts (2022)

Many active learning and search approaches are intractable for large-scale industrial settings with billions of unlabeled examples. Existing approaches search globally for the optimal examples to label, scaling linearly or even quadratically with the unlabeled data. In this paper, we improve the computational efficiency of active learning and search methods by restricting the candidate pool for labeling to the nearest neighbors of the currently labeled set instead of scanning over all of the unlabeled data. We evaluate several selection strategies in this setting on three large-scale computer vision datasets: ImageNet, OpenImages, and a de-identified and aggregated dataset of 10 billion publicly shared images provided by a large internet company. Our approach achieved similar mAP and recall as the traditional global approach while reducing the computational cost of selection by up to three orders of magnitude, enabling web-scale active learning.
