Integrated packet loss and error control schemes in wireless multimedia data links (2002)

This paper describes a novel forward error correction (FEC) based technique, VHPG FEC, which combats packet losses and packet errors simultaneously. The scheme proposed uses a two-dimensional (2-D) coding approach in which, at the encoder, information carrying packets are arranged vertically to form the 2-D matrix. The first code is applied along the horizontal direction to form the redundancy packets mainly to recover from lost packets; the second code is applied along the vertical direction within the individual packets to minimize the bit error rate (BER). Within the group of packets, the overall effect of this scheme is the reduction in the effective packet loss and the BER without need for retransmission. The scheme is applicable in environments where the packet loss is not exclusively a result of high BER and where the transmission time constraints are critical. The adaptive extension of the scheme proposed, AVHPG FEC, is introduced to deal with dynamic wireless channel characteristics. The performance of the VHPG coding is analyzed through theoretical calculations to illustrate the choice of coding parameters for various channels.
MCL-1 Inhibits BAX in the Absence of MCL-1/BAX Interaction (2007)

The BCL-2 family of proteins plays a major role in the control of apoptosis as the primary regulator of mitochondrial permeability. The pro-apoptotic BCL-2 homologues BAX and BAK are activated following the induction of apoptosis and induce cytochrome c release from mitochondria. A second class of BCL-2 homologues, the BH3-only proteins, is required for the activation of BAX and BAK. The activity of both BAX/BAK and BH3-only proteins is opposed by anti-apoptotic BCL-2 homologues such as BCL-2 and MCL-1. Here we show that anti-apoptotic MCL-1 inhibits the function of BAX downstream of its initial activation and translocation to mitochondria. Although MCL-1 interacted with BAK and inhibited its activation, the activity of MCL-1 against BAX was independent of an interaction between the two proteins. However, the anti-apoptotic function of MCL-1 required the presence of BAX. These results suggest that the pro-survival activity of MCL-1 proceeds via inhibition of BAX function at mitochondria, downstream of its activation and translocation to this organelle.
Au-nanoparticle–bis-bipyridinium cyclophane superstructures: assembly, characterization and sensoric applications (1999)

A three-dimensional conductive superstructure of 12 ± 1 nm Au-nanoparticles was built up on a conductive (indium-doped tin oxide) glass support by means of alternating treatments with Au-nanoparticle and cyclobis(paraquat-p-phenylene) tetrachloride solutions. The structure was characterized by absorbance spectroscopy (showing layer build-up and interparticle coupling), and cyclic voltammetry of the gold surface and crosslinking bipyridinium units (showing near-monolayer packing of each nanoparticle layer and a ratio of ca. 100 crosslinker molecules for each nanoparticle). The organic crosslinker molecule acts as a receptor for π-donor substrates, thus causing the concentration of such guests at the conductive superstructured array. This effect facilitates the use of the electrode as an effective sensing matrix for p-hydroquinone, 3,4-dihydroxyphenylacetic acid, dopamine and adrenaline, to concentrations as low as 1 µM. The sensitivity of the nanostructured array is controlled by the number of receptor/Au-nanoparticle layers associated with the electrode. Control experiments reveal that the superstructured electrode exhibits selectivity which is a consequence of specific interactions between the guests and the receptor, rather than the result of surface area or microenvironmental effects.
Electrochemical Reduction of Carbon Dioxide Using a Proton Exchange Membrane (2012)

전기화학적 환원을 통한 이산화탄소의 활용을 위한 노력은 오래 전부터 계속되어 왔다. 최근에는 액체연료 중 가격이 비싸고 그 활용도가 높은 포름산의 생성을 위한 연구가 많이 진행되고 있지만 실제 포름산을 생성하고 분석하는 과정에서 효율의 개선과 분석에 어려움이 따른다. 따라서 이산화탄소 환원을 이용한 포름산 생성에 필요한 시스템의 제조, 반응 조건의 개발 및 분석 방법의 정량화가 필요하다. 본 연구에서는 이산화탄소의 전기화학적 환원을 통한 포름산의 생성을 진행하고 생성된 포름산의 양을 분석하였다. 실험에 이용된 셀은 양이온 교환막을 사용하는 대용량의 회분형 셀을 이용하였으며 전위차계를 통하여 삼전극에서 전기화학 실험을 진행하였다. 전기화학 실험은 다양한 촉매 금속을 이용하여 선형 전위 주사법과 chronoamperometry를 통해 진행했으며 이 때 기준전극은 염화은 전극을 이용하였고 상대전극은 백금 전극을 사용하였다. 실험을 통해 생성된 포름산의 농도를 high performance liquid chromatography(HPLC)를 통하여 분석하여 시스템의 적정성과 분석 방법의 유효성을 검증하였다. Electrochemical reduction of carbon dioxide has been widely studied by many scientists and researchers. Recently, the production of formic acid, which is expensive but highly useful liquid material, is receiving a great attention. However, difficulties in the electrochemical reduction process and analyzing methods impede the researches. Therefore, it is important to design an adequate system, develop the reduction process and establish the analyzing methods for carbon dioxide reduction to formic acid. In this study, the production of formic acid through electrochemical reduction of carbon dioxide was performed and concentration of the product has been analyzed. Large scale batch cell with proton exchange membrane was used in the experiment. The electrochemical experiment has been performed using a series of metal catalysts. Linear sweep voltammetry (LSV) and chronoamperometry were performed for carbon dioxide reduction and electrochemical analysis using silver chloride and platinum electrode as a reference electrode and counter electrode, respectively. The concentration of formic acid generated from the reduction was monitored using high performance liquid chromatography (HPLC). The results validate the appropriateness and effectiveness of the designed system and analyzing tool.
Peritoneal Catheters and Exit-Site Practices toward Optimum Peritoneal Access: A Review of Current Developments (2005)

There is substantial variability in catheter outcomes between centers, and this variability is more closely correlated with operator and center characteristics than with catheter design. Some catheter designs appear to impact long-term catheter success, and, in some cases, specific patient characteristics and dialysis formats combine with specific catheter designs to influence catheter survival. Most reporters prefer two-cuff designs and placement of the deep cuff at an intramuscular location. Intramuscular cuff placement results in fewer pericatheter leaks and hernias, but makes catheter removal more difficult. High-risk patients (those with previous pelvic surgery) benefit from visual inspection of the peritoneum during catheter placement, and in randomized controlled trials, catheters with pre-shaped arcuate subcutaneous segments ("swan neck" designs) reduce the risk of early drainage failure via "migration."

Infrared Kerr rotation and magnetic properties of amorphous U-Sb films (1992)

Magnetron-sputtered thin films of amorphous U-Sb with various U concentrations x have been measured in the infrared photon energy range as low as 0.65 eV using polar Kerr rotation. For x>50 at.% the polar Kerr spectra are dominated by a broad negative peak near 1 eV. For x<50 at.% this peak is absent and the negative Kerr rotation is strongly increasing towards low energies with some indication of a peak at 0.7 eV. Maximum rotation measured is 2.4 degrees at 1 eV in U/sub 51/Sb/sub 49/ at a temperature of 10 K and in a field of 3 T.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High-Performance BiHEMT HBT / E-D pHEMT Integration (2007)

We report on the status of TriQuint’s BiHEMT process--the cointegration of TriQuint’s InGaP/GaAs HBT power amplifier technology with an InGaAs/AlGaAs E/D-Mode pHEMT technology into a single GaAs process. This added pHEMT functionality over previously reported GaAs HBT/FET cointegration technologies adds an additional level of versatility and potential circuit applications. Potential applications include the cointegration of HBT power amplifier circuitry with pHEMT-based bias control and logic circuitry, RF switches, and low noise amplifiers. The growth and process technologies developed for this process, as well as the preliminary device characteristics and process features, will be described. Finally, we will describe the process and performance tradeoffs featured in the BiHEMT process.

Flow profile induced in spinneret during hollow fiber membrane spinning (1997)

A methodology is presented to establish the flow profile induced in a spinneret during the spinning of hollow fiber membranes. The flow equations are derived for a power law fluid passing through a concentric annulus. The pressure drop, the velocity profile, the shear stress profile, and the shear rate profile induced during spinning can then be determined. This type of rheological knowledge is useful if membrane structure and properties are to be related to the flow conditions experienced in the spinneret. © 1997 John Wiley & Sons, Inc.

A rare genetic variant of BPIFB4 predisposes to high blood pressure via impairment of nitric oxide signaling (2017)

BPIFB4 is associated with exceptional longevity: four single-nucleotide polymorphisms distinguish the wild-type form from a longevity-associated variant conferring positive effects on blood pressure. The effect of a rare variant (RV; allele frequency, 4%) on blood pressure is unknown. Here, we show that overexpression of RV-BPIFB4 in ex-vivo mouse vessels impairs phosphorylation of endothelial nitric oxide synthase (eNOS), blunting acetylcholine-evoked vasorelaxation; in vivo, virally mediated overexpression of RV-BPIFB4 increases blood pressure, an action absent in eNOS-deficient mice. In humans, we found RV carriers to have increased diastolic blood pressure, a finding that was more marked in subjects on anti-hypertensive medication; moreover, recombinant RV-BPIFB4 protein impaired eNOS function in ex-vivo human vessels. Thus, RV-BPIFB4 acts directly on blood pressure homeostasis and may represent a novel biomarker of vascular dysfunction and hypertension.
High accuracy subwavelength distance measurements: A variable-angle standing-wave total-internal-reflection optical microscope (2009)

We describe an extension of the total-internal-reflection microscopy technique that permits direct in-plane distance measurements with high accuracy (&lt;10 nm) over a wide range of separations. This high position accuracy arises from the creation of a standing evanescent wave and the ability to sweep the nodal positions (intensity minima of the standing wave) in a controlled manner via both the incident angle and the relative phase of the incoming laser beams. Some control over the vertical resolution is available through the ability to scan the incoming angle and with it the evanescent penetration depth.
Depinning and Collective Dynamics of Magnetically Driven Colloidal Monolayers (2012)

We study the collective dynamics of interacting paramagnetic colloids transported via a magnetic ratchet effect above a modulated periodic potential. Upon increasing the modulation frequency, the particles undergo a series of dynamic transitions, from a continuous smectic flow to a disorder flow, and later enter into a two phase flow regime, ending in a complete pinned state. In the disordered phase, the system organizes into density waves due to traffic jams, as in granular systems, while the two phase flow regime shows strong similarities with plastic flow in vortex matter. Finally, it is shown that induced attractive interactions between the moving colloids lead to enhancement of the particle current due to formation of condensed chains traveling along the modulated landscape.

Classes of Ruscheweyh-type analytic univalent functions. (2003)

Abstract. A class of univalent functions is dened by making use of the Ruscheweyh derivatives. This class provides an interesting transition from starlike functions to convex functions. In special cases it has close inter-relations with uniformly starlike and uniformly convex functions. We study the eects of certain integral transforms and convolutions on the functions in this class. A.M.S. (MOS) Subject Classication Codes. 30C45,30C50
Selenoprotein H is an essential regulator of redox homeostasis that cooperates with p53 in development and tumorigenesis (2016)

Selenium, an essential micronutrient known for its cancer prevention properties, is incorporated into a class of selenocysteine-containing proteins (selenoproteins). Selenoprotein H (SepH) is a recently identified nucleolar oxidoreductase whose function is not well understood. Here we report that seph is an essential gene regulating organ development in zebrafish. Metabolite profiling by targeted LC-MS/MS demonstrated that SepH deficiency impairs redox balance by reducing the levels of ascorbate and methionine, while increasing methionine sulfoxide. Transcriptome analysis revealed that SepH deficiency induces an inflammatory response and activates the p53 pathway. Consequently, loss of seph renders larvae susceptible to oxidative stress and DNA damage. Finally, we demonstrate that seph interacts with p53 deficiency in adulthood to accelerate gastrointestinal tumor development. Overall, our findings establish that seph regulates redox homeostasis and suppresses DNA damage. We hypothesize that SepH deficiency may contribute to the increased cancer risk observed in cohorts with low selenium levels.

화천(花川) 조즙(趙즙)의 연행(燕行)과 한시 창작 (2012)

Cho Ji(趙즙) was nominated as Dongjisa(冬至使) and Sungjolsa(聖節使) and Saunsa(謝恩使), to be sent on a diplomatic mission to Ming Dynasty in July, 1623. His diplomatic corps got to Peking by sea-line, after crossed over the Bohai Sea and went ashore at Dengzhou. As soon as his arrival, he explained the whole story about the King Injo Restoration to the Ministry of Rites etc., with Lee Kyoung-Jun(李慶全), who was the messenger for asking instructions(Juchongsa, 奏請使) had arrived earlier date. They presented the report and asked for legal ratification of the new king. The Ming royal court agreed to give seal at last, and sent diplomatic envoy to confer the title to Chosun. The work of Jocheonnok by Sea-line of Gyehae(癸亥水路朝天錄), written by Cho Ji, is not only the first hand data for understanding relation between Chosun and Ming Dynasty, but also an important information for understanding the tributary trading and the paying sections in the East Asia at that time. His another work, Responding Poems in Peking( 燕行酬唱錄), records some poems spreading in the main envoys with Lee Kyoung-Jun. The poems reflects the diplomatic activities, social customs of Ming Dynasty, homesickness and object-chanting recollecting past memories with high literary value.
A qualitative exploration of the media's influence on UK women's views of breastfeeding (2021)

Background In the UK, rates of exclusive breastfeeding at 6 months are at 1%, highlighting the need to encourage and improve the support provided to women to initiate and continue breastfeeding and to improve infant and maternal health. This study aimed to qualitatively explore the influence of media on the intention to initiate and continue breastfeeding. Methods This ethnographic study recruited 40 women; 31 with children and nine of childbearing age (19–28 years), with the intention to have children. Data were collected with semi-structured interviews and analysed using thematic analysis. Results Five themes associated with sociocultural influences on breastfeeding perceptions and behaviour were identified: family influence, privacy, media as a double-edged sword, negative exposure to breastfeeding and planned behaviour versus experience. Conclusions Media influences strengthened preconceived notions of breastfeeding. Social media can play an important role in maintaining breastfeeding though support but can also put undue negative pressure on mothers who struggle to breastfeed.
Graphical description for Hardware-in-the-loop simulation (2008)

Hardware-in-the-loop (HIL) simulations are more and more used to assess performances of electric drives before their insertion on a whole system. But HIL simulation requires a lot of subsystems and control parts. A graphical description is used in this paper in order to organise HIL simulation. Two examples are given with experimental results: an electric vehicle traction system and a wind generator.
Activation of heparin cofactor II by heparin and dermatan sulfate. (1984)

Heparin cofactor II is a glycoprotein present in human plasma at a concentration of approximately 1.2 microM. It inhibits thrombin by forming a stable, 1:1 complex with the protease. The rate of complex formation is increased approximately 1,000-fold by heparin or dermatan sulfate. Heparin cofactor II appears to be the only thrombin inhibitor in plasma that can be activated by dermatan sulfate. Platelet factor 4 abolishes the activation of heparin cofactor II by dermatan sulfate, but plasma histidine-rich glycoprotein does not. Heparin cofactor II is activated by dermatan sulfate oligosaccharides that are at least 12-14 sugar residues in length and contain a high-affinity binding site for the inhibitor protein.
Initiation of RNA synthesis<i>in vitro</i>by vesicular stomatitis virus: single Internal initiation in the presence of aurintricarboxylic acid and vanadyl ribonucleoside complexes (1983)

In the presence of aurintricarboxylic acid (ATA) and vanadyl ribonucleoside complexes (VRC), we have isolated and characterized a small RNA, product of VSV in vitro transcription. This RNA is capped and lacks poly(A) at its 3'-end. Nucleotide sequence analysis revealed that this RNA corresponds to the 5'-terminal transcription product of the N-gene. The termination of the transcription occurs precisely at the 118th base from the 3'-end of the VSV genome. Analysis of the nucleotide sequence around this region reveals a potential secondary structure. Photoreaction of the VSV with 4'-substituted psoralen fails to inhibit the synthesis of the 68-mer RNA under conditions where full length mRNA synthesis is blocked, indicating that the psoralen binding site is located further into the N-gene. Since this RNA is the only in vitro transcription product synthesized under these conditions, the existence of two types of polymerase activities, one for the synthesis of leader RNA and one for mRNA, is suggested.
Designing a trust chain for a thin client on a live Linux cd (2007)

CD-boot Linuxi is a live Linux environment, which is easy to use because it is not installed in the hard disk, but simply boots directly from a CD. This helps protect the sensitive information because a clean environment can be prepared at boot time. To insure this environment protects sensitive information, we adapted the trusted computing technology to define a trustworthy environment.
Integrin α <sub>v</sub> β <sub>3</sub> mediates rotavirus cell entry (2000)

Rotavirus strains differ in their need for sialic acid (SA) for initial binding to the cell surface; however, the existence of a postattachment cell receptor, common to most, if not all, rotavirus strains, has been proposed. In the present study, antibodies to the alpha(v) and beta(3) integrin subunits, and the alpha(v)beta(3) ligand, vitronectin, efficiently blocked the infectivity of the SA-dependent rhesus rotavirus RRV, its SA-independent variant nar3, and the neuraminidase-resistant human rotavirus strain Wa. Vitronectin and anti-beta(3) antibodies, however, did not block the binding of virus to cells, indicating that rotaviruses interact with alpha(v)beta(3) at a postbinding step, probably penetration. This interaction was shown to be independent of the tripeptide motif arginine-glycine-aspartic acid present in the natural ligands of this integrin. Transfection of CHO cells with alpha(v)beta(3) genes significantly increased their permissiveness to all three rotavirus strains, and the increment of virus infectivity was reverted by incubation of these cells either with antibodies to beta(3) or with vitronectin. These findings implicate alpha(v)beta(3) integrin as a cellular receptor common to neuraminidase-sensitive and neuraminidase-resistant rotaviruses, and support the hypothesis that this integrin could determine, at least in part, the cellular susceptibility to rotaviruses.
