New Diversity-Embedding STBC Constructions (2006)

Diversity-embedding space-time codes, introduced in S.N. Diggavi et al. (2003), embed a high-diversity code within a high-rate code making opportunistic use of the channel fading conditions. They encode the information symbols into layers each at a prescribed rate-diversity operating point; thus providing an unequal error protection capability. Previous diversity-embedding space-time block codes in S.N. Diggavi et al. (2003) were presented only for 4 transmit antennas. In this paper, we present three new constructions for 2, 3, and 4 transmit antennas by varying the relative transmit power levels between the layers without violating the total transmit power constraint. The relative power scaling factor is optimized (off-line as a function of the constellation size) to achieve a desirable tradeoff between the available coding gains of the transmission layers while controlling the peak to minimum transmit power ratio
Volume‐integral‐equation‐based analysis of transient electromagnetic scattering from three‐dimensional inhomogeneous dielectric objects (2001)

A novel technique for analyzing transient electromagnetic scattering from three‐dimensional inhomogeneous dielectric targets is proposed. An integral equation for the electric flux density throughout the scatterer is constructed by invoking the electromagnetic volume equivalence principle. This equation is solved using a marching‐on‐in‐time scheme in which the electric flux density is expanded in space by volumetric rooftop basis functions defined on a tetrahedral mesh and in time by piecewise polynomials. The proposed method is validated for representative dielectric structures by comparison via Fourier transformation of scattering data obtained with this method and various frequency domain techniques.
Overhead conductor dynamic thermal rating measurement and prediction (2011)

The integration of a power line sensor network (PLSN) has been proposed to monitor such a utility asset's status for maximizing existing power grid utilization with minimal risk of degradation and for extending the lifetime of said assets. Six USi Power Donut 2 (PD2) devices were used on 115kV transmission lines of a utility partner. The included sensors and wireless data communications system allow for the transmission of data pertinent to determining the ampacity of assets. Combined with techniques laid out in the IEEE 738 Standard, accurate temperature and ampacity predictions can be made, allowing operators to make informed decisions on line utilization.
Visible Frequency Plasmon Resonator exhibiting Quality Factors exceeding 750 (2017)

We propose a plasmon resonator consisting of a cylindrical hole in a metal film that supports whispering gallery type surface plasmon polariton modes exhibiting record-high quality factors (>750) in the visible frequency range.
Hepatocellular Sinusoidal Membrane Organic Anion Transport and Transporters (1996)

This review focuses on oatp, a rat liver protein that has been cloned on the basis of its ability to transport organic anions such as bilirubin and sulfobromophthalein (BSP). Although other proteins have been suggested as having bilirubin or BSP transport activity, these data have primarily been indirect, and their cloning and expression have not yet been accomplished. Although preliminary data suggest that organic anion transporting polypeptide (oatp) accounts for a significant amount of BSP transport into the hepatocyte, there is certainly the possibility that other transporters exist. In addition, oatp appears to be a member of a new family of integral membrane transport proteins that may have overlapping substrate specificities. Organic anions such as bilirubin and sulfobromophthalein (BSP) circulate bound tightly to albumin from which they are rapidly extracted by hepatocytes. This process of organic anion uptake has been the subject of extensive investigation over many years. Although details remain unresolved, much has been learned recently regarding the mechanisms of organic anion transport. This article will examine the history and current status of this field.
N-Alkyl-4-boronopyridinium Halides versus Boric Acid as Catalysts for the Esterification of α-Hydroxycarboxylic Acids (2005)

[reaction: see text] Boric acid is a highly effective catalyst for the dehydrative esterification reaction between equimolar mixtures of alpha-hydroxycarboxylic acids and alcohols. In contrast, N-methyl-4-boronopyridinium iodide (2a) is a more effective catalyst than boric acid for the similar esterification in excess alcohol. A heterogeneous catalyst, such as N-polystyrene-bound 4-boronopyridinium chloride, is also an effective catalyst and can be recovered by filtration.

Defective Apoptotic Cell Phagocytosis Attenuates Prostaglandin E2 and 15-Hydroxyeicosatetraenoic Acid in Severe Asthma Alveolar Macrophages (2005)

A decrease in AMphis LPS-responsiveness in severe asthma is manifested by defective apoptotic cell uptake and reduces secretion of inflammatory mediators. This may contribute to the chronicity of inflammation and remodeling in lungs of patients with asthma.

Effect of Urethane RIM Morphology on Deviation from Second-Order, Straight-Line Dependence (1985)

Conversion levels of polymerization at the deviation points from straight line dependence of the second order reaction graphs were correlated with the contents of rigid segments and of plasticizer in the urethane RIM formulations. Experimental data of exothermic temperature and of conversion levels versus reaction time were obtained in an adiabatic reactor and were programmed by a regression method using a computer. Formation of fringed micelle crystallites in the process of urethane RIM polymerization was a factor influencing deviation from the straight line dependence of regular kinetics. The crystalline aggregates were evaluated by the permanent set values and at three levels of temperature by the stress relaxation method.
Suitability of Lactobacillus plantarum SPC-SNU 72-2 as a Probiotic Starter for Sourdough Fermentation (2019)

In sourdough fermentation, lactic acid bacteria perform important roles in the production of volatile and antimicrobial compounds, and exerting health-promoting effects. In this study, we report the probiotic properties and baking characteristics of <i>Lactobacillus plantarum</i> SPC-SNU 72-2 isolated from kimchi. This strain is safe to use in food fermentation as it does not carry genes for biogenic amine production (<i>i.e.</i>, <i>hdc</i>, <i>tdc</i>, and <i>ldc</i>) and shows no β-hemolytic activity against red blood cells. The strain is also stable under simulated human gastrointestinal conditions, showing tolerance to gastric acid and bile salt, and adheres well to colonic epithelial cells. Additionally, this strain prevents pathogen growth and activates mouse peritoneal macrophages by inducing cytokines such as tumor necrosis factor-α, interleukin (IL)-6, and IL-12. Furthermore, the strain possesses good baking properties, providing rich aroma during dough fermentation and contributing to the enhancement of bread texture. Taken together, <i>L. plantarum</i> SPC-SNU 72-2 has the properties of a good starter strain based on the observation that it improves bread flavor and texture while also providing probiotic effects comparable with commercial strains.
Caspase-1 (interleukin-1β-converting enzyme) is inhibited by the human serpin analogue proteinase inhibitor 9 (1999)

The regulation of caspases, cysteine proteinases that cleave their substrates after aspartic residues, is poorly understood, even though they are involved in tightly regulated cellular processes. The recently discovered serpin analogue proteinase inhibitor 9 (PI9) is unique among human serpin analogues in that it has an acidic residue in the putative specificity-determining position of the reactive-site loop. We measured the ability of PI9 to inhibit the amidolytic activity of several caspases. The hydrolysis of peptide substrates by caspase-1 (interleukin-1beta-converting enzyme), caspase-4 and caspase-8 is inhibited by PI9 in a time-dependent manner. The rate of reaction of caspase-1 with PI9, as well as the rate of substrate hydrolysis of the initial caspase-PI9 complex, shows a hyperbolic dependence on the concentration of PI9, indicative of a two-step kinetic mechanism for inhibition with an apparent second-order rate constant of 7x10(2) M(-1).s(-1). The hydrolysis of a tetrapeptide substrate by caspase-3 is not inhibited by PI9. The complexes of caspase-1 and caspase-4 with PI9 can be immunoprecipitated but no complex with caspase-3 can be detected. No complex can be immunoprecipitated if the active site of the caspase is blocked with a covalent inhibitor. These results show that PI9 is an inhibitor of caspase-1 and to a smaller extent caspase-4 and caspase-8, but not of the more distantly related caspase-3. PI9 is the first example of a human serpin analogue that inhibits members of this class of cysteine proteinases.
Design methodology for IBM ASIC products (1996)

The IBM ASIC design methodology enables a product developer to fully incorporate the high-density, high-performance capabilities of the IBM CMOS technologies in the design of leading-edge products. The methodology allows the full exploitation of technology density, performance, and high testability in an ASIC design environment. The IBM ASIC design methodology builds upon years of experience within IBM in developing design flows that optimize performance, testability, chip density, and time to market for internal products. It has also been achieved by using industry-standard design tools and system design approaches, allowing IBM ASIC products to be marketed externally as well as to IBM internal product developers. This paper describes the IBM ASIC design methodology, and then focuses on the key areas of the methodology that enable a customer to exploit the technology in terms of performance, density, and testability, all in a fast-time-to-market ASIC paradigm. Also emphasized are aspects of the methodo logy that allow IBM to market its design experience and intellectual property.
Resveratrol analogue, HS-1793, induces apoptotic cell death and cell cycle arrest through downregulation of AKT in human colon cancer cells (2016)

Resveratrol, a polyphenolic compound, is a naturally occurring phytochemical and is found in a variety of plants, including grapes, berries and peanuts. It has gained much attention for its potential anticancer activity against various types of human cancer. However, the usefulness of resveratrol as a chemotherapeutic agent is limited by its photosensitivity and metabolic instability. In this study the effects of a synthetic analogue of resveratrol, HS-1793, on the proliferation and apoptotic cell death were investigated using HCT116 human colon cancer cells. Although this compound has been reported to have anticancer activities in several human cancer cell lines, the therapeutic effects of HS-1793 on human colon cancer and its mechanisms of action have not been extensively studied. HS-1793 inhibited cell growth and induced apoptotic cell death in a concentration-dependent fashion. Induction of apoptosis was determined by morphological changes, cleavage of poly(ADP-ribose) polymerase, alteration of Bax/Bcl-2 expression ratio, and caspase activations. Flow cytometric analysis revealed that HS-1793 induced G2/M arrest in the cell cycle progression in HCT116 cells. Furthermore, HS-1793 showed more potent anticancer effects in several aspects than resveratrol in HCT116 cells. In addition, HS-1793 suppressed Akt and the phosphatidylinositol-3 kinase/Akt inhibitor LY294002 was found to enhance its induction of apoptosis. Thus, these findings suggest that HS-1793 have potential as a candidate chemotherapeutic agent against human colon cancer.

The functional landscape of mouse gene expression (2004)

We conclude that 'functional genomics' strategies based on quantitative transcriptional co-expression will be as fruitful in mammals as they have been in simpler organisms, and that transcriptional control of mammalian physiology is more modular than is generally appreciated. Our data and analyses provide a public resource for mammalian functional genomics.
On the Influence of Boolean Encodings in SAT-Based ATPG for Path Delay Faults (2008)

Automatic Test Pattern Generation (ATPG) is an important task to ensure that a chip functions correctly. For high speed chips, testing for dynamic fault models such as the path delay fault model becomes more and more important. While classical algorithms for ATPG reach their limit, the significance of algorithms to solve the Boolean Satisfiability (SAT) problem grows due to recent developments of powerful SAT solvers. However, ATPG is not always a purely Boolean problem. For generating robust test patterns for delay faults, multiple-valued logics are needed. To apply a (Boolean) SAT solver on a problem modeled in multiple-valued logic, a Boolean encoding has to be used. In this paper, we consider the problem of SAT-based ATPG for the robust path delay fault model where a 19- valued logic is used and provide a detailed study on the influence of the chosen Boolean encoding on the performance of test generation. Further, we show a method to identify efficient encodings and show the behavior of these encodings on ISCAS benchmarks and large industrial circuits.
A High-Density L-Shaped Backscattering Chipless Tag for RFID Bistatic Systems (2018)

Chipless radiofrequency identification (RFID) technology is very promising for sensing, identification, and tracking for future Internet of Things (IoT) systems and applications. In this paper, we propose and demonstrate a compact 18-bit, dual polarized chipless RFID tag. The proposed tag is based on L-shaped resonators designed so as to maximize the spectral and spatial encoding capacities. The proposed RFID tag operates an over 4 GHz frequency band (i.e., 6.5 GHz to 10.5 GHz). The tag is simulated, fabricated, and tested in a nonanechoic milieu. The measured data have shown good agreement with the simulation results, with respect to resonators’ frequency positions, null depth, and null bandwidth over the operating spectrum. The proposed design achieves spectral and spatial encoding capacities of 4.5 bits/GHz and 18.8 bits/cm 2 , respectively. This, in turn, gives an encoding density of 4.7 bits/GHz/cm 2 . For code identification, we exploit the frequency content of the backscattered signals and identify similarity/correlation features with reference codes.
Eight-Channel Data Set for Clinical EEG Transmission Over Dial-Up Telephone Network (1974)

Telephone telemetry is becoming increasingly more applicable to health care delivery. Technical characteristics and results of field testing of a new eight-channel constant-bandwidth (CBW) frequency-modulated data set are described in this communication. These tests have shown that eight channels of quality EEG can now be successfully transmitted simultaneously over one conventional telephone line. Economic considerations and other applications are discussed.
Sodium–carboxylate contact ion pair formation induces stabilization of palmitic acid monolayers at high pH (2017)

Sea spray aerosols (SSA) are known to have an organic coating that is mainly composed of fatty acids. In this study, the effect of pH and salt on the stability and organization of a palmitic acid (PA) monolayer is investigated by surface vibrational spectroscopy and molecular dynamics simulations. Results indicate that alkyl chain packing becomes more disordered as the carboxylic headgroup becomes deprotonated. This is associated with packing mismatch of charged and neutral species as charged headgroups penetrate deeper into the solution phase. At pH 10.7, when the monolayer is ∼99% deprotonated, palmitate (PA<sup>-</sup>) molecules desorb and solubilize into the bulk solution where there is spectroscopic evidence for aggregate formation. Yet, addition of 100 mM NaCl to the bulk solution is found to drive PA<sup>-</sup> molecules to the aqueous surface. Free energy calculations show that PA<sup>-</sup> molecules become stabilized within the interface with increasing NaCl concentration. Formation of contact -COO<sup>-</sup>:Na<sup>+</sup> pairs alters the hydration state of PA<sup>-</sup> headgroups, thus increasing the surface propensity. As salts are highly concentrated in SSA, these results suggest that deprotonated fatty acids may be found at the air-aqueous interface of aerosol particles due to sea salt's role in surface stabilization.
Optimal microgrid component sizing using mixed integer linear programming (2014)

This paper proposes a novel method for determining the optimal number of renewable energy and storage components in a microgrid given typical load profiles, local pricing regime, and capital costs. Case studies using solar panels and advanced lead acid battery modules are performed under residential, commercial, and off-grid sites. Simple mixed integer linear programming (MILP) optimization problems are formulated, presented, and solved in each scenario where economic analysis highlights the utility of the proposed approach.
Details of the structure of bound excitons and bound multiexciton complexes in Si (1977)

The high resolution photoluminescence spectra reported here reveal new details of the structure of both bound excitons and bound multiexciton complexes in donor and acceptor doped Si. The bound exciton and bound multiexciton complexes in Si containing P impurities are found to have excited states, as was postulated in a recent shell-model of the bound multiexciton complexes. Several new features of the luminescence due to bound excitons and bound multiexciton complexes in acceptor doped Si are also found to be in agreement with the shell-model. In contrast to previous studies, we find no reason to doubt the original bound multiexciton complex explanation of the luminescence line series which are seen in lightly doped Si. The implications of these results are also discussed in relation to previously reported interpretations of the photoluminescence spectra of donor-doped Ge.
Variation in antimicrobial activity of lactoferricin-derived peptides explained by structure modelling (2004)

Antimicrobial peptides bovine lactoferricin (LfcinB) and human lactoferricin (LfcinH) are produced from the respective lactoferrin, but are more active than their precursors. Despite sequence homology, the bovine peptide and its derivatives are more active than their human homologs. Such differences between not only the peptides and their precursor but also between the bovine and the human peptides could relate to structural differences. Upon sequence alignment of both peptides with their parental proteins, the structural differences observed between the bovine lactoferrin (BLf) and LfcinB were also found between the human lactoferrin (HLf) and the LfcinH. The helical structures in HLf are replaced by b-strands separated by a strong turn in LfcinH suggesting an antiparallel b-sheet structure similar to LfcinB. MIC assays with HLP-2 and BLP-2, 11-residue peptides derived from the active core of both Lfcins, against Escherichia coli, showed that the bovine derivative, BLP-2, is more active than its human homolog HLP-2. Both 3D models for HLP-2 and BLP-2 showed that the b-strand is centred between the aromatic residues giving both side chains the same orientations. The displacement towards the N-terminus observed for the b-strand in HLP-2, compared with its central location in BLP-2, could be less favourable to membrane interaction and therefore responsible for the decrease in activity. Such a model suggests for LfcinH a mechanism similar to the one observed for LfcinB, where the absence of long-range interaction, present in lactoferrin, destabilises the first alpha helix, as observed in solution and, upon interaction with the membrane, could result in the formation of a b-strand, as observed in the presence of LPS. The location of the b-strand in relation to the positive charges, seems to define the efficiency of the activity of the peptide and may explain the difference in activity obtained between HLP-2 and BLP-2.
Floquet-Bloch Analysis for Distributed Feedback Quantum Cascade Lasers With a Non-Rectangular Top-Metal Grating Profile (2019)

A detailed description of a numerical model based on the Floquet-Bloch approach for designing distributed feedback quantum cascade lasers with a non-rectangular top-metal grating profile is presented. The numerical methods resulting in efficient numerical calculations and allowing for the accounting of over thirty partial waves are discussed. The practical examples show that a change in grating shape can change the coupling coefficient and surface loss by over a factor of two and should, therefore, be carefully controlled in quantum cascade laser design and fabrication.
