Ab initiocalculation of pressure coefficients of band gaps of silicon: Comparison of the local-density approximation and quasiparticle results (1989)

The pressure coefficients of band gaps of silicon are calculated with use of a first-principles quasiparticle approach. For comparison, the same quantities are also computed within the Hohenberg-Kohn-Sham local-density approximation (LDA). In both cases, the calculations were performed for volumes corresponding to pressures between 0 and 150 kbar using ab initio norm-conserving pseudopotentials. The electron self-energy in the quasiparticle calculation is obtained with use of a first-order expansion in the dressed Green's function G and the screened Coulomb interaction W with local fields. The quasiparticle results show a linear dependence of changes in the band gaps on lattice constant, while the dependence on pressure deviates from linearity at high pressure. The LDA band-gap pressure coefficients, obtained using three commonly used exchange-correlation potential forms, are shown to be very close to the quasiparticle values for the whole range of crystal volumes we considered. At some of the volumes considered, the LDA band gaps are negative. Both sets of pressure-coefficient results are in very good agreement with available experimental values for Si.

Three dimeric hydrolyzable tannins having a valoneoyl group, rugosins D (1), E (2) and F (3), and a trimeric hydrolyzable tannin having two valoneoyl groups, rugosin G (4), were isolated from flower petals of Rosa rugosa (Rosaceae), and their structures including the orientation of the valoneoyl groups were established.
Evidence against tetrapod-wide digit identities and for a limited frame shift in bird wings (2019)

In crown group tetrapods, individual digits are homologized in relation to a pentadactyl ground plan. However, testing hypotheses of digit homology is challenging because it is unclear whether digits represent distinct and conserved gene regulatory states. Here we show dramatic evolutionary dynamism in the gene expression profiles of digits, challenging the notion that five digits have conserved developmental identities across amniotes. Transcriptomics shows diversity in the patterns of gene expression differentiation of digits, although the anterior-most digit of the pentadactyl limb has a unique, conserved expression profile. Further, we identify a core set of transcription factors that are differentially expressed among the digits of amniote limbs; their spatial expression domains, however, vary between species. In light of these results, we reevaluate the frame shift hypothesis of avian wing evolution and conclude only the identity of the anterior-most digit has shifted position, suggesting a 1,3,4 digit identity in the bird wing.
Self-Discharge of Graphite Electrodes at Elevated Temperatures Studied by CV and Electrochemical Impedance Spectroscopy (2004)

We propose a new method for the kinetic treatment of self-discharge of intercalation electrodes based on a combination of cyclic voltammetry (CV) and chronopotentiometry under net zero current conditions. This was applied to composite graphite electrodes in 1 M dimethyl polycarbonate at four different temperatures from 25 to 80°C, and was quantitatively proved for small degrees of self-discharge. The degree of self-discharge and the self-discharge current, were shown to substantially increase with the increase in temperature. Self-discharge experiments, which continued for 50 h, were complemented by detailed impedance characterizations of the gradually discharged electrodes, which show an increase in the diameter of the high-frequency semicircles (HFS) with open-circuit time at different temperatures. A comparison between Arrhenius plots for the HFS, the chemical diffusion coefficient, and the self-discharge current may create a basis for a new method of "electrochemical temperature spectroscopy" for identification of the nature of the rate-determining step of self-discharge for different temperature ranges. Our results are discussed in light of studies by others of self-discharge phenomena and mechanisms (Li-graphite electrodes). © 2004 The Electrochemical Society. All rights reserved.
Extending the range of primary nursing (1993)

One of the key achievements of the primary nursing system was to put the patient at the forefront of care and raise the status of clinical nursing. The values associated with primary nursing, however, need to be adopted by the whole organisation. The author highlights what actions need to be taken to maintain the momentum of primary nursing and urges the introduction of case management.

FSSRE: Fusing Semantic Feature and Syntactic Dependencies Feature for threat intelligence Relation Extraction (2021)

Threat intelligence relation extraction plays an important role in threat intelligence text analysis and processing. To extract the relation between two threat entities in a sentence, we develop a novel framework called FSSRE which fuses sematic feature and syntactic dependencies feature for threat intelligence relation extraction. We utilize graph convolutional networks (GCN) to extract syntactic dependencies features, and utilize Sentence-BERT to extract contextual semantic features. To keep vital information with irrelevant content removed to the most extent, we further apply a novel pruning strategy, SDP-VP, to the input trees. With retaining the shortest path and nodes that are hops away from nodes on the shortest path, we give the edge connected to the verb nodes a weight of times. We create an advanced persistent threat (APT) intelligence entities and intra-sentence relations dataset, APTER-SENT, for that there is no public dataset can be used for relation extraction research in the threat intelligence field. Experimental results on APTER-SENT demonstrate improved performance over competitive baselines. At the same time, we also conducted experiments on the SemEval-2010 dataset. The results of the experiment indicate that our method is still effective on this dataset.

Fabrication and Characterization of Poly(3-hexylthiophene)-Based Field-Effect Transistors with Silsesquioxane Gate Insulators (2008)

The preparation of organic–inorganic hybrid gate dielectrics of poly(methyl silsesquioxane) (PMSQ) at a low processing temperature has been studied for use in organic field-effect transistors (OFETs) by the solution process. It is found that the electrical resistivity of a PMSQ film synthesized by a sol–gel method is significantly influenced by the synthesis conditions such as the type of organic solvent used and water content. PMSQ films prepared in toluene show a high resistivity of over 1014 Ω cm even at a low thermal treatment of 150 °C, which is attributed to the decrease in the silanol concentration of the PMSQ films. Top-contact OFET fabricated on a PMSQ-coated SiO2 gate dielectric using poly(3-hexylthiophene) exhibits mobility improvement similarly to devices with self-assembled monolayer-modified SiO2 dielectrics.
Pipelining in algorithms with quantizer loops (1991)

High-speed implementation of signal processing algorithms for digital transmission is addressed. The internal feedback or recursion in these algorithms makes it difficult to implement recursive systems concurrently using either pipelining or parallelism. In the past, look-ahead computation techniques were successfully applied to create necessary concurrency in linear recursive and some nonlinear recursive operations (such as the add-compare-select operation). Novel computation approaches are proposed, and the look-ahead technique is extended to pipeline the feedback loops containing finite-level quantizers. Approaches to pipeline piecewise-linear recursive systems are presented. The proposed architectures are suitable for real-time high-speed implementation of quantizer loop operations where the levels of quantizer and the order of the loops are small.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Android users in the wild: Their authentication and usage behavior (2016)

In this paper, we performed a longitudinal field study with 41 participants, who installed our monitoring framework on their Android smartphones and ran it for at least 20 days. We examined how unlocking mechanisms perform in the wild in terms of time it takes to authenticate and error-rate, and how the users' choices of the unlocking mechanisms are linked to the different patterns of smartphone usage. Based on our findings, we offer insights into improving Android unlocking mechanisms and related user experience.
Ketoconazole Versus Nystatin as Prophylaxis Against Fungal Infection for Lymphoma Patients Receiving Chemotherapy (1987)

We evaluated the efficacy and toxicity of ketoconazole versus nystatin antimycotic prophylaxis in a prospective randomized study of 32 patients receiving intensive weekly outpatient combination chemotherapy for non-Hodgkin's lymphoma with crossover to the other drug if failure occurred. Thirteen patients were assigned to nystatin and 19 to ketoconazole. Fungal infections occurred in three patients receiving nystatin (16%) and one patient receiving ketoconazole (8%); one patient refused his assigned drug due to taste intolerance. Including the crossover courses of drug, the failure rate associated with ketoconazole was 6% while that for nystatin was 20% (p = 0.23). We favor ketoconazole as antifungal prophylaxis during antilymphoma chemotherapy because of at least equivalent and possibly superior efficacy, better acceptance by patients, easier administration, and systemic absorption.
Free radical‐scavenging properties of lignin (1998)

Lignin is one of the major components of dietary fiber. It is a complex hydrophobic molecule that typically occurs in cell walls with heteroxylans. Our experimental data show that lignin is a free radical scavenger. When the NADH-phenazine methosulfate-nitro blue tetrazolium free radical-producing system is used, an alkali-lignin concentration of 46.29 micrograms/ml that causes 50% inhibition of uric acid production by xanthine oxidase (IC50) is a scavenger of superoxide anion radicals. Spectrophotometric assay has shown that alkali-lignin with an IC50 of 59.08 micrograms/ml inhibits the activity of xanthine oxidase, one of the enzymes related to the production of superoxide anion radicals, and presents a mixed-type noncompetitive inhibition pattern. Using the deoxyribose method, we have found that alkali-lignin is a hydroxyl radical scavenger with an IC50 of 250 micrograms/ml, and using the thiobarbituric acid method, we can see that alkali-lignin inhibits nonenzymatic and enzymatic lipid peroxidation with an IC50 of 72 and 100 micrograms/ml, respectively. Alkali-lignin also hinders the activity of glucose-6-phosphate dehydrogenase, another enzyme related to the generation of superoxide anion radicals, with an IC50 of 123.6 micrograms/ml, and obstructs the growth and viability of cancer (HeLa) cells in a dose-dependent manner. Our experimental results suggest another mechanism whereby the free radical-scavenging activity of lignin in dietary fiber may be involved in the fiber-colon cancer interaction. We also suggest that the ability of dietary fiber to protect against colon cancer may be partly determined by the amount of lignin in dietary fiber as well as the free radical-scavenging ability of lignin.

A Short History of the Consideration of Sex Differences in Biomedical Research — Lessons for the In Vitro Community from Animal Models and Human Clinical Trials (2023)

In recent decades, it has become clear that in many fields - such as drug development, particularly with regard to drug dosage and specific disease treatment - the sex of a patient must be taken into consideration, in view of the fact that male and female physiology and pathophysiology show many differences of practical concern. While, in the last decade or so, considerable efforts have been undertaken to consider the sex of the animals during the planning of experiments, this topic has just started to be acknowledged in <i>in vitro</i> studies. Cells in such studies seem mainly to be used according to their availability, without considering the sex of the original donor. Even when such information is available, experimental data are reported without overtly detailing this information. In recent years, the increasing complexity of <i>in vitro</i> models (e.g. stem cell-based, 3-D cultures, organoids, or organ-on-a-chip technologies) has contributed to systems that better resemble the human <i>in vivo</i> situation. However, the issue of the sex of the experimental organisms being used has not yet been properly taken up by the cell culture community. Thus, alongside the increasing complexity of multicell-type models, we now see <i>in vitro</i> models that incorporate cells from both male and female origin - this representing, in fact, a genetic chimaera. Here, we aim to discuss where we are currently, with respect to considering the sex of any animals or humans used in experiments, and we try to identify what is lacking in the cell culture field, in order to help facilitate change.
Combined LIBS-Raman for remote detection and characterization of biological samples (2015)

Laser-Induced Breakdown Spectroscopy (LIBS) and Raman Spectroscopy have rich histories in the analysis of a wide variety of samples in both in situ and remote configurations. Our team is working on building a deployable, integrated Raman and LIBS spectrometer (RLS) for the parallel elucidation of elemental and molecular signatures under Earth and Martian surface conditions. Herein, results from remote LIBS and Raman analysis of biological samples such as amino acids, small peptides, mono- and disaccharides, and nucleic acids acquired under terrestrial and Mars conditions are reported, giving rise to some interesting differences. A library of spectra and peaks of interest were compiled, and will be used to inform the analysis of more complex systems, such as large peptides, dried bacterial spores, and biofilms. These results will be presented and future applications will be discussed, including the assembly of a combined RLS spectroscopic system and stand-off detection in a variety of environments.

Possible role of interferon tau on the bovine corpus luteum and neutrophils during the early pregnancy (2015)

When pregnancy is established, interferon tau (IFNT), a well-known pregnancy recognition signal in ruminants, is secreted by embryonic trophoblast cells and acts within the uterus to prepare for pregnancy. IFNT acts as an endocrine factor on the corpus luteum (CL) to induce refractory ability against the luteolytic action of PGF2 α. Hypothesising that IFNT may influence not only the uterine environment but also the CL in cows via local or peripheral circulation, we investigated qualitative changes in the CL of pregnant cows during the maternal recognition period (day 16) and the CL of non-pregnant cows. The CL of pregnant animals had a higher number of neutrophils, and the expression of interleukin 8 (IL8) mRNA and its protein was higher as well as compared with the CL of non-pregnant animals. Although IFNT did not affect progesterone (P4) secretion and neutrophil migration directly, it stimulated IL8 mRNA expression on luteal cells (LCs), influencing the neutrophils, resulting in the increased migration of IFNT-activated neutrophils. Moreover, both IFNT-activated neutrophils and IL8 increased P4 secretion from LCs in vitro. Our novel finding was the increase in neutrophils and IL8 within the CL of pregnant cows, suggesting the involvement of IFNT function within the CL toward establishment of pregnancy in cows. The present results suggest that IFNT upregulates neutrophil numbers and function via IL8 on LCs in the CL of early pregnant cows and that both neutrophils and IL8, stimulated by IFNT, are associated with an increase in P4 concentrations during the maternal recognition period in cows.

Jamming detection on 802.11p under multi-channel operation in vehicular networks (2015)

Multichannel operation has been suggested for vehicular networks in order to support simultaneously safety and non-safety applications. Without awareness of lower layers, safety messages may be generated out of the control channel interval that leads to synchronous contention at the beginning of control channel interval (CCHI). The jamming attacks at this period are difficult to detect as they can be confused with collisions in contention. In this work, we proposed a detection method that can distinguish between packet lost due to normal collisions and due to jamming attacks. An analytical model is also introduced and validated in order to study the efficiency and the precision of the proposed detection method. Obtained numerical results from analytical model and network simulation show that our detection method has a high detection probability under reactive jamming attacks.
Intensification of a fermentation process for producing lactic acid in a ceramic membrane combined bioreactor system (2013)

A membrane-based filtration process could efficiently reduce the cost of lactic acid production, which is mainly due to its downstream separation and purification steps. In order to achieve high-volumetric productivity of lactic acid, ceramic micro (MF)- and ultrafiltration (UF) membranes are selected to separate the lactic acid from the fermentation broth. For a successful combination of separation unit and fermentation system, membranes should be characterized separately for the determination of membrane performance and the impact of process parameters on it. In this work, the statistical design of experiment was explored to investigate the effects of the physical properties of fermentation broth (cell density, glucose concentration) and process parameters of filtration (transmembrane pressure (TMP) and tangential flow velocity (CFV)) on membrane performances (flux and membrane fouling). In the meantime, the cell density was tracked with the scattered light sensor (FAUDI Aviation AFGUARD®), which is designed for in situ measurement of particulate matters and firstly developed for online control of biotechnical processes. Under the application of AFGUARD® sensor in the filtration process the cell rejection could be online monitored efficiently and economically. The results indicated that the 50 nm and 100 kDa membranes had the better performances (higher flux and lower fouling) in comparison to the other membranes (0.2 μm and 20 kDa) under the same operating condition. Biomass was successfully remained in retentate and not found in permeate. In the further experiments, the filtration unit will be integrated to the bioreactor system in order to establish a continuous fermentation process in which cell growth kinetics, lactic acid productivity and membrane performance will be studied.
Expression of MEF2 Genes during Human Cardiac Development. (1999)

To better understand the regulatory mechanisms in gene expression of human cardiomyocytes, we studied the expression of MEF2 genes encoding transcription factors during the course of cardiac development. Expression of all four MEF2 transcripts (MEF2A, MEF2B, MEF2C, and MEF2D) were detected in all developmental stage of the human heart, while Mef2b transcripts were down-regulated in mouse heart development. Although none of the MEF2 genes, besides mouse Mef2b, exhibited any remarkable quantitative change in their transcripts, qualitative changes in MEF2 transcripts were found during the course of cardiac development. In particular, MEF2D transcripts showed prominent changes by alternative splicing in the perinatal period. MEF2D transcripts containing the 21-base exon (exon b) were predominantly expressed after birth. At the same time, transcripts of the alpha myosin heavy chain (alphaMHC) gene increased after birth, as the splicing pattern in transcripts of the cardiac troponin T (cTnT) gene changed to decrease the transcripts of cTnT1 after birth. These changes seemed to be correlated with the alternative splicing changes of MEF2 genes, especially MEF2D. The alternative splicing as well as transcriptional regulation in MEF2 genes might be important for regulating the alphaMHC gene and the maturation of cardiomyocytes.
