Plastic deformation of bulk and micropillar single crystals of Mo5Si3 with the tetragonal D8 structure (2022)

The plastic deformation behavior of single crystals of Mo5Si3 with the tetragonal D8m structure has been investigated in compression as a function of crystal orientation and temperature (1200–1500°C) in the bulk form and as a function of crystal orientation and specimen size at room temperature in the micropillar form. The slip system of {112¯}<111> is identified to be the only one that operates at high temperatures above 1200°C in bulk crystals, while any plastic flow is not detected at room temperature in micropillar crystals. The critical resolved shear stress (CRSS) for {112¯}<111> slip at room temperature estimated from the extrapolation of the temperature dependence of CRSS obtained for bulk crystals is considerably higher than fracture stresses obtained for micropillar crystals, indicating that the room-temperature brittleness is due in principle to the difficulty in dislocation motion arising from the very high CRSS value. The value of fracture toughness evaluated with a chevron-notched micro-beam specimen with a notch plane parallel to (001) is 1.54 MPa•m1/2, which is comparable to those reported for other transition-metal (TM) silicides of the TM5Si3-type. The selection of {112¯} slip plane and the dissociation of the 1/2<111> dislocation on the slip plane are discussed based on generalized stacking fault energy (GSFE) curves theoretically calculated by first-principles calculations.
Key role of the 5-HT1A receptor addressing protein Yif1B in serotonin neurotransmission and SSRI treatment (2020)

These data support the concept that Yif1B plays a critical role in 5-HT1AR functioning and brain 5-HT homeostasis. The opposite changes in its expression observed in anxious or depressive states and after therapeutic fluoxetine treatment suggest that Yif1B might be involved in vulnerability to anxiety and depression, and fluoxetine efficacy.
Antigen-Antibody Interaction-Based GaN HEMT Biosensor for C3G Detection (2022)

In this paper, we demonstrate the design and fabrication of an AlGaN/GaN High Electron Mobility Transistor (HEMT) as a bio sensing platform. Bio-compatible functionalization process with thioglycolic acid and antibody-antigen immobilization process with EDC-NHS chemistry is optimized, and the AlGaN/GaN HEMT biosensor is validated using recombinant C3G (RAPGEF1) protein and an indigenously developed mouse monoclonal antibody (clone 3F6mAb). The designed biosensor with its extended source-drain pads and inter-digital gate sensing design increases sensitivity of device to detect low concentration of biological samples. C3G protein is detected by antigen-antibody conjugation over extended functionalized sensing gate area which resulted in 36.2% change in drain current output and the corresponding antigen is detected up to 500 pg/ml. The biosensor shows a resolution in mA range, which is easily implementable by circuit due to low noise factor. It can therefore be adopted for use to detect antigens in very small biological samples, required in diagnostic assays of bio-medical applications.

A compact and directive UWB antenna for biomedical applications (2007)

Ultra wideband (UWB) (3.1–10.6 GHz) microwave imaging systems offer much promise for biomedical applications such as cancer detection because of their good penetration and resolution characteristics. The underlying principle of UWB cancer detection is a significant contrast in dielectric properties, which is estimated to be greater than 2:1 between normal and cancerous tissue. UWB imaging systems have shown promising results in the detection of tumours for early breast cancer detection [1]. In UWB imaging systems, a very narrow pulse is transmitted from an UWB antenna and allowed to impinge on the body. As the pulse propagates through various tissues, reflections occur at interfaces between different tissues. This scattered signal can be received using another UWB antenna, or array of antennas, and used to map different layers of the body. For an accurate imaging system with high resolution and dynamic range, the transmitting/receiving UWB antenna should be planar, compact in size and directive with high radiation efficiency. Several UWB antenna designs have been proposed for the use in medical imaging systems [2-4]. Each has its own merits and drawbacks. Some of the proposed antennas have a non-planar structure while others have low gain and/or low radiation efficiency. The low efficiency is a major parameter
The Lion's Algorithm: A New Nature-Inspired Search Algorithm (2012)

Natural Computing is an efficient computing field that intends to develop search, optimization and machine learning algorithms by the inspiration of nature's behavior in problem solving circumstances. In the same way, numerous biologically or naturally inspired search and optimization algorithms have been proposed in the literature. This paper proposes a novel solution search algorithm called lion's algorithm. The natural inspiration behind the proposed algorithm is lion's social behavior that aids to keep the mammal be strong in the world. The interpretation of such social behavior to algorithmic perspective helps in searching out highly optimal solutions from a huge solution space. The algorithm solves both single variable and multi-variable cost function problems through the generation of binary structured and integer structured lion, respectively. The algorithm is implemented and tested using De-Jong's Type I function and the results are compared against the evolutionary programming. The test results show the algorithm performance under varying sizes of solution spaces.
Wireless nanosensors and systems (WiNS) (2009)

Wireless Nanosensors and Systems research project has been investigating a systems approach to designing sensors systems. The effort is multifaceted and ranges from the design of low-cost sensors for various applications, such as biomedical or structural health monitoring, to the design of wireless interfaces and protocols with suitable networking and design of protocols to transmit sensor data from one place to another securely and to the design of appropriate applications themselves. The research team has been developing a system-engineering framework that forms the basis for collaborative activities across three campuses, University of Arkansas at Fayetteville, University of Arkansas at Little Rock and Arkansas State University, that captures the relationship between sensors, wireless interfaces, the network, the testbed that facilitates applications-level communications.

Development of TNFSF as molecular adjuvants for ALVAC HIV-1 vaccines (2010)

A phase III clinical trial finished in Thailand recently showed that an ALVAC HIV-1 vaccine prime-gp120 protein boost vaccination regimen could modestly protect persons from HIV-1 infection, demonstrating that development of an effective and safe HIV-1 preventive vaccine is possible. ALVAC HIV-1 vaccines are candidate HIV-1 vaccines based on canarypox vectors. Previous clinical trials proved that ALVAC HIV-1 vaccines were safe but weak in immunogenicity when used in human subjects. We have been exploring to use tumor necrosis factor superfamily (TNFSF) members as adjuvants to enhance the immunogenicity of ALVAC HIV-1 vaccines. In this commentary, we will summarize our findings in using two TNFSF molecules, CD40L and OX40L, as adjuvants for an ALVAC HIV-1 vaccine in mouse model. We will also briefly discuss the challenges and prospects of using TNFSF molecules as adjuvants for HIV-1 vaccines in humans.
Crystal Structure of Nonstoichiometric Tetranuclear Platinum Compound, cis-Diammineplatinum α-Pyrrolidone Violet, [Pt4(NH3)8(C4H6NO)4](PF6)2(NO3)2.56·5H2O (1985)

Abstract Nonstoichiometric platinum tetranuclear compound, cis-Diammineplatinum α-Pyrrolidone Violet, [Pt4(NH3)8(C4H6NO)4)(PF6)2(NO3)2.56·5H2O, has been synthesized and the crystal structure has been solved with X-ray diffraction analysis. The crystal is triclinic with the space group of P\bar1 and cell dimensions of a=13.530(8), b=19.242(9), c=10.222(3) Å, α=96.56(9), β=93.82(9), γ=74.64(8)°, V=2547.4 Å3, and Z=2. The structure have been solved by heavy atom method and the final discrepancy index R1 was 0.094 and R2 was 0.090. The cation is structurally identical with those of cis-Diammineplatinum α-Pyridone Yellow(PPY), [Pt4(NH3)8(C5H4NO)4]4+, cis-Diammineplatinum α-Pyridone Blue(PPB), [Pt4(NH3)8((C5H4NO)4]5+, and cis-Diammineplatinum α-Pyrrolidone Tan(PPT), [Pt4(NH3)8(C4H6NO)4]6+, and consists of four platinum atoms linked in a chain with bridging pyrrolidone ligands. Each platinum atom is cis coordinated by two ammine ligands and either two exocyclic oxygen atoms or two deprotonated ring nitrogen atoms of α-pyrrolidone ligands. The Pt-Pt bond distances are 2.848(2), 2.875(2), 2.839(2), and 2.875(2) Å, which are intermediate between those of PPY and PPB, indicating that the average platinum oxidation state is between 2.0 and 2.25. According to the potentiometric: oxidative titration of the compound using Ce(IV), the average platinum oxidation state is 2.14 and therefore the compound is considered to consist of 44% of [Pt4(NH3)8(C4H6NO)4]4+ and 56% of [Pt4(NH3)8(C4H6NO)4]5+.
Experiment analysis in newspaper topic detection (2002)

We present several methods for topic detection on newspaper articles, using either a general vocabulary or topic-specific vocabularies. Specific vocabularies are determined manually or statistically. In both cases, we aim at finding the most representative words of a topic. Several methods have been experimented, the first one is based on perplexity, this method achieves a 100% topic identification rate, on large test corpora, when the two first propositions are taken into account. Other methods are based on statistical counts and achieve 94% of identification on smaller test corpora. The major challenge of this work is to identify topics with only few words in order to be able, during speech recognition, to determine the best adequate language model.
Mid-infrared upconversion imaging using femtosecond pulses (2019)

Mid-infrared (mid-IR) imaging and spectroscopic techniques have been rapidly evolving in recent years, primarily due to a multitude of applications within diverse fields such as biomedical imaging, chemical sensing, and food quality inspection. Mid-IR upconversion detection is a promising tool for exploiting some of these applications. In this paper, various characteristics of mid-IR upconversion imaging in the femtosecond regime are investigated using a 4f imaging setup. A fraction of the 100 fs, 80 MHz output from a Ti:sapphire laser is used to synchronously pump an optical parametric oscillator, generating 200 fs mid-IR pulses tunable across the 2.7–4.0 μm wavelength range. The signal-carrying mid-IR pulses are detected by upconversion with the remaining fraction of the original pump beam inside a bulk LiNbO3 crystal, generating an upconverted field in the visible/near-IR range, enabling silicon-based CCD detection. Using the same pump source for generation and detection ensures temporal overlap of pulses inside the nonlinear crystal used for upconversion, thus resulting in high conversion efficiency even in a single-pass configuration. A theory is developed to calculate relevant acceptance parameters, considering the large spectral bandwidths and the reduced interaction length due to group velocity mismatch, both associated with ultrashort pulses. Furthermore, the resolution of this ultrashort-pulsed upconversion imaging system is described. It is demonstrated that the increase in acceptance bandwidth leads to increased blurring in the upconverted images. The presented theory is consistent with experimental observations.
The Formalist Crusade of Antonin Scalia (2013)

This chapter describes Antonin Scalia's orginalism, which is distinctive in several respects and is more concerned with restricting judicial lawmaking than with the value of popular sovereignty. It is not believed that Scalia has successfully resolved the internal tensions in his thinking. His recent theoretical writings seem to have reverted to a more simplistic version of originalism. His best-known opinion on the separation of powers is his dissent in a case concerning the constitutional status of the independent counsel. Originalism plays a limited role in some of Justice Scalia's most notable opinions despite its centrality in his thinking about judicial review. Hence, despite his views on originalism, he has tended in practice to invoke entrenched interpretations of constitutional provisions by either the Court itself or by long-standing public consensus.
Simultaneous forward and backward Raman scattering in low-attenuation single-mode fibers (1986)

The coupled steady-state rate equations that govern the simultaneous forward and backward first Stokes line Raman scattering in low-loss single-mode optical fibers have been solved. The theory includes the feedback due to end-surface reflections. Experimental measurements of threshold power and scattering behavior above threshold were found to yield close agreement with theoretical predictions.

Evolution of uplink MIMO for LTE-advanced (2011)

The evolution of LTE uplink transmission toward MIMO has recently been agreed in 3GPP, including the support of up to four-layer transmission using precoded spatial multiplexing as well as transmit diversity techniques. In this article, an overview of these uplink MIMO schemes is presented, along with their impact on reference signals and DL control signaling. Receivers suitable for uplink MIMO are presented, and their link performances are compared.
Improving the performance of probabilistic neural networks (2003)

A methodology for selection of appropriate widths or covariance matrices of the Gaussian functions in implementations of PNN (probabilistic neural network) classifiers is presented. The Gram-Schmidt orthogonalization process is employed to find these matrices. It has been shown that the proposed technique improves the generalization ability of the PNN classifiers over the standard approach. The result can be applied to other Gaussian-based classifiers such as the radial basis functions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Calcitonin gene‐related peptide in gingival crevicular fluid in periodontal health and disease (1999)

The aims of the present study were to investigate whether calcitonin gene-related peptide (CGRP) was present in gingival crevicular fluid in both periodontal health and disease and to study the relationship with periodontal inflammation. Gingival crevicular fluid (GCF) was collected from a healthy, a gingivitis and a periodontitis site in 18 subjects with periodontitis and from a healthy site in 19 subjects without periodontitis. The volume of GCF was measured and each sample subsequently analysed for CGRP by radioimmunoassay. In subjects with periodontitis, CGRP immunoreactivity (CGRP-IR) was not detected in any periodontitis sites, nor in 67% of gingivitis and 28% of periodontally-healthy sites. The total amount of CGRP-IR was significantly elevated in periodontally healthy (p=0.0015) and gingivitis (p=0.027) compared with periodontitis sites. CGRP-IR was present in 89% of the healthy sites sampled in control subjects at comparable levels to those in healthy sites in periodontitis subjects. It is concluded that in periodontal inflammation, particularly in deep pockets, constituents of GCF process and degrade CGRP.
The measurement and tuning of SiC Diode Voltage Doubler represented as diffusion-welded stack (2018)

In this paper, the results of measurements and settings for various output parameters of device are presented. The object of research was the prototype of a voltage multiplier represented as the diffusion-welded stack. Two options of voltage multiplier prototypes have been considered: first is the scheme with external capacitors and the second is the multiplier of the vertical composition using the diode's own capacitance. The capacitance-voltage as well as oscillograms of input and output signals for both multiplier prototypes are presented.
Air travel demand and airline seat inventory management (1987)

Many airlines practice differential pricing of fare products that share a common inventory of available seats on an aircraft. Seat inventory management is the process of limiting the number of seats made available to each fare class. The objective of both strategies is to maximize the total revenues generated by the mix of fare products sold for a flight. This dissertation first examines the evolution of airline marketing and seat in-ventory management practices. A demand segmentation model is developed to help explain current airline fare structures. A conceptual model of the consumer choice process for air travel is then presented, and extended to describe the airline reserva-tions process and the probabilistic elements that can affect seat inventory control. A survey of current airline practice in this area revealed that seat inventory control is an ad-hoc process which depends heavily on human judgement. Past work on quantitative approaches has focused on large-scale optimization models that solve simple representations of the problem. A primary objective of this research was the
Activation of β-Catenin Signaling in Prostate Cancer by Peptidyl-Prolyl Isomerase Pin1-Mediated Abrogation of the Androgen Receptor-β-Catenin Interaction (2006)

Androgen receptor (AR) interacts with β-catenin and can suppress its coactivation of T cell factor 4 (Tcf4) in prostate cancer (PCa) cells. Pin1 is a peptidyl-prolyl cis/trans isomerase that stabilizes β-catenin by inhibiting its binding to the adenomatous polyposis coli gene product and subsequent glycogen synthase kinase 3β (GSK-3β)-dependent degradation. Higher Pin1 expression in primary PCa is correlated with disease recurrence, and this study found that Pin1 expression was markedly increased in metastatic PCa. Consistent with this result, increased expression of Pin1 in transfected LNCaP PCa cells strongly accelerated tumor growth in vivo in immunodeficient mice. Pin1 expression in LNCaP cells enhanced β-catenin/Tcf4 transcriptional activity, as assessed using Tcf4-regulated reporter genes, and increased expression of endogenous Tcf4 and c-myc. However, in contrast to results in cells with intact PTEN and active GSK-3β, Pin1 expression in LNCaP PCa cells, which are PTEN deficient, did not increase β-catenin. Instead, Pin1 expression markedly inhibited the β-catenin interaction with AR, and Pin1 abrogated the ability of AR to antagonize β-catenin/Tcf4 binding and transcriptional activity. These findings demonstrate that AR can suppress β-catenin signaling, that the AR-β-catenin interaction can be regulated by Pin1, and that abrogation of this interaction can enhance β-catenin/Tcf4 signaling and contribute to aggressive biological behavior in PCa.

Development of the Purchase Terminal for Nationwide Interoperable Transportation Card System in Korea (2010)

During the past decade, the transportation smart card system and its market has been developed and grown significantly. The essential infrastructure for the system has been implemented throughout the country. The authors can see there are several types of terminals or gates used in all forms of public transportation. Each terminal has its own operable transportation card. A key problem is that interoperability is not supported, either in transportation methods (e.g. bus, train, etc.), or in regional areas. The authors are required to develop a novel interoperable transportation smart card system, called the OCAP card (One Card All Pass in Korea) system based on the Korea Industry Standard. This paper proposes the purchase terminal, one of the components of the OCAP card system. The authors have designed and developed the purchase terminal which is able to recognize the existing regular card and the OCAP card with a standard PSAM inside. Through running a test-bed, the authors expect their proposed terminal could be used with a reasonable degree of certainty and reliability.
TESTICULAR SPERM EXTRACTION WITH INTRACYTOPLASMIC SPERM INJECTION FOR NONOBSTRUCTIVE AZOOSPERMIA: TESTICULAR HISTOLOGY CAN PREDICT SUCCESS OF SPERM RETRIEVAL (1999)

Critical examination of the most advanced pattern of spermatogenesis from open diagnostic testis biopsy allows prediction of sperm retrieval success with testicular sperm extraction. In this study population spermatozoa were retrieved in 58% of attempts. When this testicular sperm was used with intracytoplasmic sperm injection, clinical pregnancy rate was 55% for men with nonobstructive azoospermia.
Mechanism of the slow induction of apolipoprotein A-I synthesis by retinoids in cynomolgus hepatocytes: involvement of retinoic acid and retinoid X receptors (1997)

We showed previously that retinoids stimulate apolipoprotein A-I (apoA-I) synthesis in cultured cynomolgus hepatocytes only after a 24-h lag phase. Here we report on the biochemical background of the slow response, the requirement for high retinoic acid concentrations, and the involvement of different retinoid receptors. The time course of the effect of 10 microM all-trans retinoic acid (at-RA) on apoA-I mRNA levels and protein secretion were comparable, i.e., minor increases were observed after a 24-h incubation and mRNA levels were increased 2.2- and 3.5-fold after 48 h and 72 h, respectively. In contrast, apoA-I gene transcription was already increased (2.6-fold) after a 4-h incubation with 10 microM at-RA. At-RA disappeared rapidly from the cultures: after 2 h of incubation 40% of the added amount was left and after 24 h only 2%. RAR beta mRNA and gene expression were increased after incubation with 10 microM at-RA, whereas RAR alpha and RXR alpha mRNA levels and expression remained unchanged. No transcriptional activity and mRNA for other retinoid receptors were detectable. Both RAR-selective (TTNPB) and RXR-selective (3-methyl-TTNEB) agonists induced apoA-I synthesis at 1 and 10 microM. These results show that i) the slow increase in apoA-I secretion is caused by a slow increase of its mRNA level; ii) the apoA-I gene transcription in cynomolgus hepatocytes is induced rapidly by retinoids; iii) the added at-RA disappeared rapidly from the cultures, explaining the necessity for high initial concentrations; iv) RLR alpha and/or RAR beta and RXR alpha are involved in the activation of apoA-I expression by retinoids.
