A Novel Monitoring Method of RF Characteristics Variations for Sub-0.1&#x003BC;m MOSFETs with Precise Gate-resistance Model (2006)

RF characteristics for sub-0.1μm MOSFETs such as fT, fmax and their variations are estimated from the DC and capacitance parameters. A new RF gate resistance model with a silicide-polysilicon interface resistance is a key factor to estimate the RF characteristics precisely. The variations of RF characteristics are also inferred from correlation coefficient between the RF parameters and the DC and capacitance parameters. This method is effective in monitoring RF characteristics and their variations for scaled-down, RF/mixed-signal circuits at the chip fabrication.
The Role of IFN-β during the Course of Sepsis Progression and Its Therapeutic Potential (2017)

Sepsis is a complex biphasic syndrome characterized by both pro- and anti-inflammatory immune states. Whereas early sepsis mortality is caused by an acute, deleterious pro-inflammatory response, the second sepsis phase is governed by acute immunosuppression, which predisposes patients to long-term risk for life-threatening secondary infections. Despite extensive basic research and clinical trials, there is to date no specific therapy for sepsis, and mortality rates are on the rise. Although IFN-β is one of the most-studied cytokines, its diverse effects are not fully understood. Depending on the disease or type of infection, it can have beneficial or detrimental effects. As IFN-β has been used successfully to treat diverse diseases, emphasis has been placed on understanding the role of IFN-β in sepsis. Analyses of mouse models of septic shock attribute a pro-inflammatory role to IFN-β in sepsis development. As anti-inflammatory treatments in humans with antibodies to TNF-α or IL1-β resulted disappointing, cytokine modulation approaches were discouraged and neutralization of IFN-β has not been pursued for sepsis treatment. In the case of patients with delayed sepsis and immunosuppression, there is a debate as to whether the use of specific cytokines would restore the deactivated immune response. Recent reports show an association of low IFN-β levels with the hyporesponsive state of monocytes from sepsis patients and after endotoxin tolerance induction. These data, discussed here, project a role for IFN-β in restoring monocyte function and reversing immunosuppression, and suggest IFN-β-based additive immunomodulatory therapy. The dichotomy in putative therapeutic approaches, involving reduction or an increase in IFN-β levels, mirrors the contrasting nature of the early hyperinflammatory state and the delayed immunosuppression phase.
Temperature-Dependent Development of Immature Stages of the Western Corn Rootworm, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae) (1988)

Larval and pupal development of western corn rootworm was studied at eight constant temperatures ranging from 15 to 33°C. Development from hatch to adult stage occurred at 15–31.5°C; no larvae completed the second stage at 33°C. Adult survival decreased and wing deformities increased significantly at 15 and 31.5°C. Optimum development and survival occurred within the temperature range of 21–30°C. Males developed faster than females in all stages at temperatures from 18–30°C, but the sexes have a similar lower thermal threshold of development estimated to be near 9°C. The relationship between developmental rate and temperature was described for both sexes in all stages using linear and nonlinear equations. The information presented will facilitate the development of phenological models for this important pest species.
Tyrosinase related protein 1 (TYRP1/gp75) in human cutaneous melanoma (2011)

Melanoma prognosis is based on specific pathological features at the primary lesion. In metastatic patients, the extent of lymph node involvement is also an important prognosis indicator. Many progression markers both in tissues and serum, including circulating tumor cells, have been studied and new molecular markers are awaited from high-throughput screenings to discriminate between clinical stages and predict disease progression. The present review focuses on human tyrosinase related protein 1 also known as gp75 glycoprotein (Tyrp1/gp75), a melanosomal protein involved in the pigmentary machinery of the melanocyte and often used as differentiation marker, with a special emphasis on its emerging roles in the malignant melanocyte and melanoma progression.
Single-Image Super-Resolution Using Sparse Regression and Natural Image Prior (2010)

This paper proposes a framework for single-image super-resolution. The underlying idea is to learn a map from input low-resolution images to target high-resolution images based on example pairs of input and output images. Kernel ridge regression (KRR) is adopted for this purpose. To reduce the time complexity of training and testing for KRR, a sparse solution is found by combining the ideas of kernel matching pursuit and gradient descent. As a regularized solution, KRR leads to a better generalization than simply storing the examples as has been done in existing example-based algorithms and results in much less noisy images. However, this may introduce blurring and ringing artifacts around major edges as sharp changes are penalized severely. A prior model of a generic image class which takes into account the discontinuity property of images is adopted to resolve this problem. Comparison with existing algorithms shows the effectiveness of the proposed method.
Low-Voltage Poly(3-Hexylthiophene)/Poly(Vinyl Alcohol) Field-Effect Transistor and Inverter (2012)

We report on bottom-gate top-contact organic field-effect transistors that use regioregular poly(3-hexylthiophene) (rr-P3HT) as a channel semiconductor and poly(vinyl alcohol) as a gate insulator. We determine that the field-effect mobility of the rr-P3HT is 0.08 <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$\hbox{cm}^{2} \cdot\hbox{V}^{-1}\cdot\hbox{s}^{-1}$</tex></formula> , the threshold voltage is <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX"> $-$</tex></formula> 1.1 V, and the on/off current ratio is <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$\hbox{10}^{3}$</tex></formula> , demonstrating the transistor operation in an inverter.
Enzymic degradation of uracil-containing DNA. 3. Partial purification and characterization of a uracil DNA N-glycosidase from Bacillus subtilis (1977)

A uracil specific DNA N-glycosidase activity has been partially purified from crude extracts of Bacillus subtilis. The enzyme has a molecular weight of approximately 24 000 with no subunit structure. It has no requirement for any known cofactors but is inhibited in the presence of Co2+, Fe2+, or Zn2+. The enzyme is specific for uracil in single- and double-stranded deoxyribonucleopolymers and does not release free uracil from RNA or from poly(rU):poly(dA). In addition, neither Udr, dUMP, nor dUTP is recognized as substrate. The enzyme will attack small poly(dU) oligomers but the minimum size recognized as substrate is (pU)4. This enzyme may have a role in the repair (by base excision) or uracil in DNA arising either by incorporation during DNA synthesis or by deamination of cytosine in DNA.
Structures of cell wall mannans of pathogenic Candida tropicalis IFO 0199 and IFO 1647 yeast strains (1994)

We conducted a structural analysis of the cell wall mannans isolated from two Candida tropicalis strains, IFO 0199 and IFO 1647, exhibiting strong agglutinabilities against anti-Candida factor sera 5 and 6. The products released from these mannans by acid treatment were identified as the oligosaccharides, from biose to pentaose, consisting solely of beta-1,2-linked mannopyranose units corresponding to common epitopes of Candida albicans serotypes A and B (factor 5). Mild acetolysis of acid- and alkali-treated mannans produced large amounts of hexaose and heptaose, Man rho beta 1-2Man rho beta 1-2Man rho alpha 1-2Man rho alpha 1-2Man rho alpha 1-2Man and Man rho beta 1-2Man rho beta 1-2Man rho beta 1-2Man rho alpha 1-2 Man rho alpha 1-2Man, corresponding to the C. albicans serotype A-specific epitopes (factor 6). However, the homologous pentaose, Man rho beta 1-2Man rho alpha 1-2 Man, was not generated by this procedure. The oligosaccharides (biose to hexaose) obtained from the mannans by conventional acetolysis were composed exclusively of alpha-1,2-linked mannopyranose units. Therefore, the mannans of C. tropicalis IFO 0199 and IFO 1647 do not have the alpha-1,3-linked mannopyranose units previously observed in the mannans of C. albicans and Candida stellatoidea. The results of this study and previous findings indicate that the similarity of the antigenicities of three Candida species, C. albicans serotype A, C. stellatoidea type II, and C. tropicalis, reside in the beta-1,2 and alpha-1,2 linkages containing oligomannosyl side chain (factor 6) in the cell wall mannan.
Absence of a ``Threshold Effect'' in the Energy Loss of Slow Protons Traversing Large-Band-Gap Insulators (1997)

The electronic stopping cross section $\ensuremath{\varepsilon}$ of slow hydrogen projectiles in large-band-gap insulators has been measured at energies of a few keV. Even at velocities as low as ${v}_{0}/3$ $({v}_{0}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}c/137)$, we find no influence of the band gap on the velocity dependence of $\ensuremath{\varepsilon}$, contrary to the case of gaseous targets with similar minimum excitation energy. The magnitude of $\ensuremath{\varepsilon}$ and its essentially linear velocity dependence allow us to arrive at the following conclusion: Electron promotion processes contribute substantially to stopping due to formation of molecular orbitals. This points towards the existence of a bound electron state at a proton that moves slowly in an insulator. A simple model based on the calculation of molecular orbital correlation diagrams for the H/LiF collision system supports the idea of local reduction of the band gap of an insulating target.
Liner Collection Cone and pH Effects on Postthaw Motility, Staining, and Acrosomes of Bovine Spermatozoa (1991)

Sixteen ejaculates were collected, four each from four bulls, using artificial vaginas with polyethylene or rubber liner collection cones in a crossover design experiment. The ejaculates were diluted with egg yolk-citrate extender at pH 6.4 or 7.2, cooled, glycerolated, equilibrated, packaged in .5-ml French straws, frozen in nitrogen vapor, and stored in liquid nitrogen. Thirty frozen straws from each ejaculate were thawed rapidly (46.5 degrees C for 12 s), pooled, and then incubated at 46.5 degrees C for periodic evaluation of progressive motility, differential staining, and acrosome morphology under thermal stress conditions. The postthaw motility of spermatozoa and percentage of unstained cells were higher both when collected in polyethylene than in rubber and when extended at pH 7.2 vs. 6.4, but no interaction was found between liner collection cone composition and pII for postthaw motility. Retention of spermatozoan motility during incubation under thermal stress was greater for cells collected in polyethylene, but not different due to pH. Neither pH nor composition of liner collection cone had an effect on postthaw acrosomal scores, but the time required for a 50% increase in severely damaged acrosomes was greater for spermatozoa collected in polyethylene than in rubber liner collection cones.
A real-time robust global localization for autonomous mobile robots in large environments (2010)

Global localization aims to estimate a robot's pose in a learned map without any prior knowledge of its initial pose. Achieving highly accurate global localization remains a challenge for autonomous mobile robots especially in large-scale unstructured outdoor environments. This paper introduces a real-time reliable global localization approach with the capability of addressing the kidnapped robot problem using only laser sensors. Our approach includes four steps: 1) local Simultaneous Localization and Mapping 2) map matching 3) position tracking and 4) localization quality evaluation. For sensor perception, we use occupancy grid method to represent robot environment. A novel pyramid grid-map based coarse-to-fine matching approach is proposed to improve the localization accuracy. Experimental results including an outdoor environment of 25, 000 m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> are presented to validate the feasibility and reliability of the proposed approach.
Stabilities of single-layer and bilayer steps on Si(001) surfaces (1987)

The formation energies of single- and double-layer steps on Si(001) surfaces were calculated. For each case, two configurations with surface dimerization axes normal or parallel to the step edge were examined. Single-layer steps are found to have the lowest formation energy. Bilayer steps become energetically more favorable on surfaces misoriented towards [110] or [1\ifmmode\bar\else\textasciimacron\fi{}10] axes where low- and high-energy single-layer steps are forced to alternate with each other.
Graphene Modified Cotton Textiles (2011)

The graphene oxides are abundant in hydroxyl and carboxyl groups that are close to the reactive dyes. These structural features gave a possibility to modify textiles to enhance the conductivity by using the dyeing and finishing method. Herein, graphene modified cotton textiles are fabricated by soaking cotton cloth in graphene oxide colloid. After reduction, the modified textiles exhibit an improved conductivity. The present work contributed a facile strategy for graphene modified textiles.
A Specification and Tool for the Configuration of&#x0A0;&#x0A0;REST Applications (2009)

Service-enabled applications have become a need in todaypsilas environment of mashups and Web 2.0. Traditional SOAP-based Web services and Representational State Transfer (REST) are alternatives as the popularity of these applications grows. REST has recently gained visibility and its lower entry barrier seems adequate for many applications. This paper proposes the configuration of an applicationpsilas REST services using XML files. A remote administration service is also described in order to support fine grained run-time changes to the configuration of an applicationpsilas REST services. A GUI tool is presented for the creation and editing of these files as well as for providing an interface for the administration service. Finally, a default implementation of a server that supports the administration service is presented.
Metagenomic Functional Potential Predicts Degradation Rates of a Model Organophosphorus Xenobiotic in Pesticide Contaminated Soils (2018)

Chemical contamination of natural and agricultural habitats is an increasing global problem and a major threat to sustainability and human health. Organophosphorus (OP) compounds are one major class of contaminant and can undergo microbial degradation, however, no studies have applied system-wide ecogenomic tools to investigate OP degradation or use metagenomics to understand the underlying mechanisms of biodegradation <i>in situ</i> and predict degradation potential. Thus, there is a lack of knowledge regarding the functional genes and genomic potential underpinning degradation and community responses to contamination. Here we address this knowledge gap by performing shotgun sequencing of community DNA from agricultural soils with a history of pesticide usage and profiling shifts in functional genes and microbial taxa abundance. Our results showed two distinct groups of soils defined by differing functional and taxonomic profiles. Degradation assays suggested that these groups corresponded to the organophosphorus degradation potential of soils, with the fastest degrading community being defined by increases in transport and nutrient cycling pathways and enzymes potentially involved in phosphorus metabolism. This was against a backdrop of taxonomic community shifts potentially related to contamination adaptation and reflecting the legacy of exposure. Overall our results highlight the value of using holistic system-wide metagenomic approaches as a tool to predict microbial degradation in the context of the ecology of contaminated habitats.
Effects of Synthetic Versus Natural Colloid Resuscitation on Inducing Dilutional Coagulopathy and Increasing Hemorrhage in Rabbits (2008)

: TEG and thrombin generation assays identified more severe coagulopathy development with H and D than A dilution, whereas plasma PT and activated partial thromboplastin time measurements did not differentiate between these colloids. These results suggest that resuscitation with albumin maintained coagulation function, decreased blood loss, and improved survival time compared with the synthetic colloids.
Generation of reactive oxygen species in blood platelets (2002)

The generation of superoxide anion radicals (O2*-) and the other reactive oxygen species (ROS) was estimated by means of cytochrome c reduction and chemiluminescence, as well in resting blood platelets and in platelets stimulated by thrombin in the presence or absence of some inhibitors of pathways involved in platelet activation. We used allopurinol (xanthine oxidase inhibitor), wortmannin (PI 3-kinase inhibitor) and staurosporine (protein kinase C inhibitor). To determine the involvement of the glutathione in ROS generation, we used L-buthionine sulfoximine (BSO) which blocks GSH synthesis. Our results confirmed that thrombin stimulates the production of ROS concomitant with metabolism of arachidonate and production of malonyldialdehyde (MDA) in blood platelets (P < 0.05) and showed that, in the presence of inhibitors, the generation of ROS in platelets (resting and stimulated) was reduced. This indicates that xanthine oxidase, PI 3-kinase or protein kinase C take part in the formation of ROS in blood platelets. Moreover, adhesion of platelets to fibrinogen and secretion of adenine nucleotides from platelets after wortmannin and staurosporine action was also inhibited. BSO not only decreased GSH level, but also reduced the amount of ROS; a correlation between the depletion of GSH and the decrease of ROS was observed (R = -0.987; P < 0.02). It is concluded that in blood platelets, ROS are produced in the receptor-mediated signaling pathways and platelet activation (arachidonic acid metabolism, the glutathione cycle, metabolism of phosphoinositoides and due to xanthine oxidase). Our results support the importance of ROS in platelet function.
Proteomic analysis and immunodetection of the bovine milk osteopontin isoforms (2012)

The aim of this study was to characterize the osteopontin (OPN) secreted in bovine milk and to determine whether the different forms are the product of spliced variants. Spliced variants of the human gene and secreted osteopontin isoforms have been reported in human tumor tissue. In bovine milk, we identified 2 major forms: one corresponding to the full-length coding transcript and a truncated version of this form. No alternative spliced transcripts were detected in the lactating mammary gland tissue, in milk somatic cells, or in peripheral blood immune cells. The 60-kDa bovine osteopontin (bOPN) and a truncated 40-kDa protein isoform were confirmed by mass spectrometry and further characterized by immunoblotting using a panel of 6 antibodies targeting different domains of the protein. Of the 3 human anti-OPN antibodies targeting the N-terminal segment of the protein, only one detected all forms on sodium dodecyl sulfate-PAGE; one human anti-OPN antibody failed to detect bOPN, whereas the other detected only the 60-kDa protein, albeit barely in its phosphorylated form. Detection was generally more sensitive when the 60-kDa protein was dephosphorylated. Two polyclonal antibodies raised against bOPN were tested: one targeting the milk-purified bOPN (bOPN-121) and one targeting a bovine epitope (synthetic peptide) corresponding to a carboxy-terminal domain of the protein (bOPN-117). The bOPN-121 antibody detected all forms irrespective of the phosphorylation status of bOPN. The bOPN-117 and the mouse anti-human OPN (hOPN-4) antibodies, which recognized different domains of the carboxy-terminal segment of the protein, also preferentially detected the dephosphorylated 60-kDa protein. Whereas phosphorylation had a major effect on detection for several antibodies, deglycosylation slightly decreased immunodetection for the tested antibodies. In particular, phosphorylation is the major posttranslational modification that influenced the weak detection capacity of several antibodies. This fact needs to be taken into account for immunodetection of milk content. In conclusion, the OPN forms secreted in bovine milk are not the product of alternative splicing. The 40-kDa protein appears to be a truncated hypophosphorylated variant of the full-length 60-kDa form, which is highly phosphorylated. Together, the proteomic and immunoblotting analyses used to characterize bovine milk OPN revealed the complex nature of the bovine milk OPN forms.
Vaccination of Jirds, Meriones unguiculatus, against Litomosoides carinii and Brugia pahangi using irradiate larvae of L. carinii. (1982)

This study has shown tht exposure of jirds to radiation-attenuated larvae of one filarial species confers resistance to another species and thus indicates the potential for developing zooprophylactic regimens for the control of human filariasis. 13 and 8 Meriones unguiculatus were vaccinated with infective 3rd stage larvae of Litomosoides carinii attenuated by 40 krad Cobalt 60 irradiation and challenged with either L. carinii or Brugia pahangi respectively. Vaccinated jirds showed a 98% reduction in the expected challenge of L. carinii and a 71% reduction in the expected challenge of B. pahangi when compared to infectious in non-vaccinated controls.
Los gitanos en Siria (2003)

hPuf-A is a member of RNA-binding PUF family that regulates mRNA translation. Redistribution of hPuf-A from the nucleolus to the nucleoplasm upon genotoxic stress modulates the poly(ADP-ribosyl)ation activity of PARP-1. Here, we report a novel function of hPuf-A involved in promoting breast cancer progression. Immunohistochemical studies showed higher expression levels of hPuf-A in stage I, II, III, and IV breast cancer specimens in contrast with those of hPuf-A in ductal carcinoma in situ. The presence of hPuf-A is highly associated with colony formation capacities in breast cancer T47D and MDA-MB-231 cells. Xenograft growth of hPuf-A-silenced and hPuf-A overexpressing MDA-MB-231 cells in nude mice was substantially in concert with colony formation capacities. This promoting effect of hPuf-A in tumorigenesis might be correlated with the regulation of its associated mRNAs, such as RbAp48 and DDX3. Collectively, hPuf-A may have diagnostic values in breast cancer progression.
