Residual stress in low pressure chemical vapor deposition SiNx films deposited from silane and ammonia (1998)

Varied SiNx films have been deposited by low pressure chemical vapor deposition from silane SiH4 and ammonia NH3 and the influences of the deposition parameters (temperature, total pressure and NH3/SiH4 gaseous ratio) on the film deposition rate, refractive index (assessed at a 830 nm wavelength), stoichiometry and thermomechanical stress are investigated and correlated. Low stress (≈600 MPa) Si3N4 films are obtained for the highest deposition temperature and the lowest total pressure but the gaseous ratio is shown to be the dominant parameter. According to the SiNx stoichiometry, silicon-rich silicon nitride and nitrogen-doped silicon (called NIDOS) depositions are obtained and compressive to tensile stresses are reported. A maximum in compressive stress is put into evidence for N/Si ratio roughly equal to 0.7 and is related to the cumulated effects of silicon nitridation and crystallization, characterizing the transition between nitrogen-doped silicon and silicon-rich silicon nitride. Finally, by considering stress, deposition rate, nonuniformity along the load and resistance to alkaline solutions, optimal (silicon-rich) silicon nitride deposition conditions are proposed for microelectromechanical applications.
Comprehensive Analysis of Prognostic and Genetic Signatures for General Transcription Factor III (GTF3) in Clinical Colorectal Cancer Patients Using Bioinformatics Approaches (2021)

Colorectal cancer (CRC) has the fourth-highest incidence of all cancer types, and its incidence has steadily increased in the last decade. The general transcription factor III (GTF3) family, comprising GTF3A, GTF3B, GTF3C1, and GTFC2, were stated to be linked with the expansion of different types of cancers; however, their messenger (m)RNA expressions and prognostic values in colorectal cancer need to be further investigated. To study the transcriptomic expression levels of GTF3 gene members in colorectal cancer in both cancerous tissues and cell lines, we first performed high-throughput screening using the Oncomine, GEPIA, and CCLE databases. We then applied the Prognoscan database to query correlations of their mRNA expressions with the disease-specific survival (DSS), overall survival (OS), and disease-free survival (DFS) status of the colorectal cancer patient. Furthermore, proteomics expressions of GTF3 family members in clinical colorectal cancer specimens were also examined using the Human Protein Atlas. Finally, genomic alterations of GTF3 family gene expressions in colorectal cancer and their signal transduction pathways were studied using cBioPortal, ClueGO, CluePedia, and MetaCore platform. Our findings revealed that GTF3 family members' expressions were significantly correlated with the cell cycle, oxidative stress, WNT/β-catenin signaling, Rho GTPases, and G-protein-coupled receptors (GPCRs). Clinically, high GTF3A and GTF3B expressions were significantly correlated with poor prognoses in colorectal cancer patients. Collectively, our study declares that GTF3A was overexpressed in cancer tissues and cell lines, particularly colorectal cancer, and it could possibly step in as a potential prognostic biomarker.
La educación integral y las nuevas bases curriculares (2019)

espanolA lo largo de las reformas educacionales que ha tenido nuestro pais, se ha intentado establecer coherencia entre los contenidos y la formacion de valores y aptitudes en los estudiantes. Sin embargo, estas pretensiones se han visto relegadas por el sistema de mediciones que tiene nuestro modelo educativo y que se traduce en pruebas estandarizadas que intenta medir el nivel de logro de los contenidos curriculares. La reforma en curso aparentemente nos ofrece la oportunidad de desarrollar una educacion integral desde una mirada innovadora y atingente a las necesidades de nuestra realidad pais, pero surgen interrogantes acerca de su aplicacion real y la relacion con el actual sistema de mediciones, el que se presenta entonces como una amenaza para las nuevas Bases Curriculares y sus proyecciones a futuro. EnglishThroughout the educational reforms that our country has had, it has tried to establish coherence between the contents and the formation of values and aptitudes in the students. However, these claims have been relegated by the measurement system that our educational model has and which results in standardized tests that attempt to measure the level of achievement of curricular content. The ongoing reform apparently offers us the opportunity to develop a comprehensive education from an innovative and attentive perspective to the needs of our country reality, but questions arise about its real application and the relationship with the current measurement system, which is presented then as a threat to the new Curriculum Bases and their future projections.
Cognition studies with pigs: Livestock cognition and its implication for production (2002)

Abstract The purpose of this paper is twofold. First, it discusses in general terms how animal production can be affected by the animals' cognitive abilities; second, it aims to introduce our work on pig cognition. We suggest that livestock cognition does not only affect production indirectly through its effects on livestock welfare, but also that cognition can have direct effects. Direct effects are evident when cognitive abilities limit feed intake, for example, or in the recognition of groupmates or offspring. We illustrate such direct effects with two case studies from pig production: voluntary feed intake after weaning and production losses associated with aggression in groups. Voluntary feed intake after weaning is affected by preweaning experiences, weaning age, and postweaning practices. Some studies suggest a link between early environment and cognitive development in piglets, as has previously been demonstrated in other species. We suggest this as a possible contributing factor to low feed intake immediately after weaning. The other case study centers on aggression in groups of pigs. Several studies indicate that some social assessment and recognition take place between individuals, allowing them to judge each other's aggressiveness and to avoid fighting once a dominance hierarchy has been established. However, the regrouping of previously familiar pigs can also lead to high aggression levels. This suggests that pigs may be able to form only short-term social memories, or that some aspects of their social memory are disrupted before regrouping. Our work shows that pigs have well-developed spatial memory abilities, which can be disrupted by common management procedures. If this were also the case for social memory, it could help explain increased aggression levels in previously familiar pigs after routine procedures. We also show that pigs are able to adjust their foraging behavior depending on the presence or absence of a subordinate, exploitable co-forager that knows where food is. This ability has potential implications for the way feed is best dispensed to pigs such that all group members can maximize their intake.
A dataset and evaluation methodology for visual saliency in video (2009)

Recently, visual saliency has drawn great research interest in the field of computer vision and multimedia. Various approaches aiming at calculating visual saliency have been proposed. To evaluate these approaches, several datasets have been presented for visual saliency in images. However, there are few datasets to capture spatiotemporal visual saliency in video. Intuitively, visual saliency in video is strongly affected by temporal context and might vary significantly even in visually similar frames. In this paper, we present an extensive dataset with 7.5-hour videos to capture spatiotemporal visual saliency. The salient regions in frames sequentially sampled from these videos are manually labeled by 23 subjects and then averaged to generate the ground-truth saliency maps. We also present three metrics to evaluate competing approaches. Several typical algorithms were evaluated on the dataset. The experimental results show that this dataset is very suitable for evaluating visual saliency. We also discover some interesting findings that would be addressed in future research. Currently, the dataset is freely available online together with the source code for evaluation.
Optical response of epitaxial films of YBa2Cu3O7−δ (1988)

We present the results of measurements of optical detection in epitaxial films of YBa2Cu3O7−δ, at wavelengths of 0.63 and 10.6 μm. In contrast to the behavior observed in granular materials, these films appear to show no evidence of nonequilibrium response (breaking of Cooper pairs by photons), but only a bolometric effect (heating of the sample by radiation) in the resistive transition regime. This suggests that epitaxial films do not contain intrinsic links weak enough to be modulated by the incident radiation. For 0.63 μm radiation, mechanically chopped at 725 Hz, measurements of a 10 μm ×90 μm bridge yield a bolometric responsivity of approximately 4×103 V/W, and a detectivity D* of more than 108 cm Hz1/2/W.
Periodontal disease and bisphosphonates induce osteonecrosis of the jaws in the rat (2011)

Bisphosphonates (BPs) are medications used commonly to treat primary and metastatic bone cancer, as well as osteoporosis. Although BPs improve bone mineral density, reduce fracture risk, and reduce hypercalcemia of malignancy, some patients develop BP-related osteonecrosis of the jaws (BRONJ). This devastating complication is defined as clinically exposed bone in the maxillofacial region for more than 8 weeks. Despite an increasing number of BRONJ cases since first reported, the disease pathophysiology remains largely unknown. Since published studies suggest a significant role for dental disease in the pathophysiology of BRONJ, we developed a BRONJ animal model where aggressive periodontal disease is induced by ligature placement around the crown of the right maxillary first molar in the presence of vehicle (veh) or zoledronic acid (ZA), a potent BP. Ligature placement induced significant alveolar bone loss, which was attenuated by ZA treatment. Osteonecrosis was observed associated with ligature-induced periodontitis in the ZA-treated group. This was seen as sequestration and extensive periosteal alveolar bone formation on micro-computed tomography (µCT) in the ligated site of BP-treated animals. Histologic examination confirmed these findings, seen as necrotic bone with diffuse loss of osteocytes and empty lacunae, rimming of the necrotic bone by squamous epithelium and inflammation, and exposure to the oral cavity. Importantly, the rat lesions were strikingly similar to those of BRONJ patients. Our data suggest that dental disease and potent BP therapy are sufficient for BRONJ development in the rat.
Application of Peanut Shells Composts in Replacement with Peat on Growth Indices and Physical and Chemical Properties of Violet Growth Media (&lt;i&gt;Viola&lt;/i&gt; spp) in Outdoor (2017)

Peanut Shells as the waste left from peanut planting, which considerable amount of compost can be used as available resources to replace with peat in cultivation of Ornamental plant growth media. So, in this experiment, five treatments in a completely randomized design with three replications were conducted in outdoor in Lahijan ornamental plants Research Station. Treatments were included: 2 peat + 1 perlite + 0 Shells Peanut composts (control), 1.5 Peat + 1 perlite + 0.5 Shells peanut compost, 1 Peat + 1 perlite + 1 Shells Peanut composts, 0.5 Peat + 1 perlite + 1.5 peanut shells compost, 0 peat + 1 perlite + 2 peanut shells compost. In this experiment growth index of violets are included, number of flower, plant height, fresh and dry weight of canopy, root length, root fresh and dry weight, and physical and chemical properties of substrates were measured. The results showed that replacement of Shells Peanut compost has a significant effect on, number of flowers, plant height, Dry weight of canopy, root fresh and dry weight in comparison to control. Increasing levels of Peanut Shells compost caused to reduce in bulk density and an increase in total porosity, Water capacity and air fill porosity.
Fabrication of polycaprolactone scaffolds using a sacrificial compression‐molding process (2005)

A method of compression-molding fine-powder blends of polycaprolactone (PCL) and poly(ethylene oxide) (PEO) and subsequently dissolving the PEO phase was investigated to prepare porous PCL scaffolds. Different mixing ratios of the two polymers from 20 to 70% PCL were used to study the effect of the mixing ratio on the morphology formation of the scaffold. The mixing ratio was found to play an important role in affecting the porosity of the scaffold and the size of pores. Murine embryonic stem cell derived osteogenic cells were utilized to test the suitability of these scaffolds in tissue engineering applications. The seeded cells were able to colonize and grow in these scaffolds. Based on the overall consideration of morphology, mechanical performance, and ability for cell attachment and proliferation, the scaffolds with approximately 30-40% PCL appear to be an appropriate choice for tissue engineering. These findings suggest that sacrificial compression-molding of PCL-PEO powder blends can be used in the generation of biocompatible scaffolds with controllable porosity and pore size and may be used for in vitro tissue engineering applications.
Unbiased guard ring for latchup-resistant, junction-isolated smart-power ICs (2002)

The measurements of the effects of high current, emitter area, and layout of unbiased guard rings are reported and explained. Measurements show a reduction of the parasitic gain by up to six orders of magnitude, while also avoiding the crosstalk and power consumption of biased rings.
Pyomelanin Production by <i>Pseudomonas aeruginosa</i> (1980)

Pseudomonas aeruginosa was successfully transformed from a pyomelanin-producing strain to a non-pyomelanin-producing strain by genetic transformation, with an average frequency of 1.17 X 10-3/recipient. Although the transformation frequency was not affected by doses of DNA between 17 and 51 microgram/ml, it was influenced by the growth phase of the recipient bacteria, i.e., it was highest in the late logarithmic phase. Biochemical functions of the transformants were the same as those of the recipient strain except for pyomelanin production. Some of them, however, showed an intermediate growth behavior and cell arrangement between the donor and recipient. The serological type of the donor strain was sometimes contransduced although a few transformants became nonagglutinable with either donor or recipient type antiserum. The pyomelanin producing activity and serological type gained of some transformants were eliminated by either subculturing in nutrient broth or acridine treatment. The results obtained suggested that the pyomelanin productivity of P. aeruginosa is controlled by a plasmid.
Observation of enhanced single longitudinal mode operation in 1.5-μm GaInAsP erbium-doped semiconductor injection lasers (1986)

We propose a new type of current injection semiconductor laser with rare-earth dopant in the active layer for achieving stable, single longitudinal mode operation. In this laser, the rare-earth/semiconductor combination is chosen such that the wavelengths of the dominant emission from the trivalent rare-earth ion internal 4f-4f transitions are shorter than that of the band-edge emission of the host semiconductor. Spectrally, the narrow optical gain due to the rare-earth ion transition will superimpose on top of the broad gain peak of the host semiconductor. Such laser diodes will attain lasing action at the rare-earth transition wavelength resulting in single longitudinal mode operation with conventional Fabry–Perot cavity. Furthermore, reproducible precise lasing wavelength insensitive to temperature variation should be possible. Such a proposed rare-earth/semiconductor injection laser was investigated with erbium doping in the GaInAsP (λ=1.55 μm) active layer of the heteroepitaxial ridge-overgrown laser. Stable, single longitudinal mode operation at 15 322 Å was obtained. Furthermore, this lasing line shifted at a slow rate of ≲1 Å/°C with heat-sink temperature. Initial results do appear to confirm this new proposed rare-earth/semiconductor laser operation scheme.
Security and Cloud Computing: InterCloud Identity Management Infrastructure (2010)

Cloud Computing is becoming one of the most important topics in the IT world. Several challenges are being raised from the adoption of this computational paradigm including security, privacy, and federation. This paper aims to introduce new concepts in cloud computing and security, focusing on heterogeneous and federated scenarios. We present a reference architecture able to address the Identity Management (IdM) problem in the InterCloud context and show how it can be successfully applied to manage the authentication needed among clouds for the federation establishment.
Bacteria help desulfurize gas (1988)

We compared the cardiovascular, hepatic and metabolic responses to individual dietary n-3 fatty acids (α-linolenic acid, ALA; eicosapentaenoic acid, EPA; and docosahexaenoic acid, DHA) in a high-carbohydrate, high-fat diet-induced model of metabolic syndrome in rats. Additionally, we measured fatty acid composition of plasma, adipose tissue, liver, heart and skeletal muscle in these rats. The same dosages of ALA and EPA/DHA produced different physiological responses to decrease the risk factors for metabolic syndrome. ALA did not reduce total body fat but induced lipid redistribution away from the abdominal area and favorably improved glucose tolerance, insulin sensitivity, dyslipidemia, hypertension and left ventricular dimensions, contractility, volumes and stiffness. EPA and DHA increased sympathetic activation, reduced the abdominal adiposity and total body fat and attenuated insulin sensitivity, dyslipidemia, hypertension and left ventricular stiffness but not glucose tolerance. However, ALA, EPA and DHA all reduced inflammation in both the heart and the liver, cardiac fibrosis and hepatic steatosis. These effects were associated with complete suppression of stearoyl-CoA desaturase 1 activity. Since the physiological responses to EPA and DHA were similar, it is likely that the effects are mediated by DHA with EPA serving as a precursor. Also, ALA supplementation increased DHA concentrations but induced different physiological responses to EPA and DHA. This result strongly suggests that ALA has independent effects in metabolic syndrome, not relying on its metabolism to DHA.
Extracting Diurnal Patterns of Real World Activity from Social Media (2021)

In this study, we develop methods to identify verbal expressions in social media streams that refer to real-world activities. Using aggregate daily patterns of Foursquare checkins, our methods extract similar patterns from Twitter, extending the amount of available content while preserving high relevance. We devise and test several methods to extract such content, using time-series and semantic similarity. Evaluating on key activity categories available from Foursquare (coffee, food, shopping and nightlife), we show that our extraction methods are able to capture equivalent patterns in Twitter. By examining rudimentary categories of activity such as nightlife, food or shopping we peek at the fundamental rhythm of human behavior and observe when it is disrupted. We use data compiled during the abnormal conditions in New York City throughout Hurricane Sandy to examine the outcome of our methods.
Correction factors for <sup>13</sup>C-labelled substrate oxidation at whole-body and muscle level (1999)

The oxidation of fatty acids, carbohydrates and amino acids can be measured by quantifying the rate of excretion of labelled CO2 following administration of 14C- or 13C-labelled substrates at whole-body and tissue level. However, there is a theoretical need to correct the oxidation rates for the proportion of labelled CO2 that is produced via oxidation but not excreted. Furthermore, depending on the substrate and position of the C label(s), there may also be a need to correct for labelled C from the metabolized substrate that does not appear as CO2, but rather becomes temporarily fixed in other metabolites. The bicarbonate correction factor is used to correct for the labelled CO2 not excreted. Recently, an acetate correction factor has been proposed for the simultaneous correction of CO2 not excreted and label fixed in other metabolites via isotopic exchange reactions, mainly in the tricarboxylic acid cycle. Changes in metabolic rate induced, for example, by feeding, hormonal changes and physical activity, as well as infusion time, have been shown to affect both correction factors. The present paper explains the theoretical and physiological basis of these correction factors and makes recommendations as to how these correction factors should be used in various physiological conditions.
Covalent Deposition of Zwitterionic Polymer and Citric Acid by Click Chemistry-Enabled Layer-by-Layer Assembly for Improving the Blood Compatibility of Polysulfone Membrane (2014)

Development of blood compatible membranes is critical for biomedical applications. Zwitterionic polymers have been proved to be resistant to nonspecific protein adsorption and platelet adhesion. In this work, two kinds of zwitterionic copolymers bearing alkynyl and azide groups are synthesized by atom transfer radical polymerization (ATRP) and subsequent reactions, namely alkynyl-poly(sulfobetaine methacrylate) (alkynyl-PSBMA) and azide-poly(sulfobetaine methacrylate) (azide-PSBMA). The copolymers are directly used to modify azido-functionalized polysulfone (PSf-N3) membrane via click chemistry-enabled layer-by-layer (LBL) assembly. Alkynyl-citric acid is then clicked onto the membrane when the outermost layer was azide-PSBMA. The chemical compositions, surface morphologies, and hydrophilicity of the zwitterionic polymer and citric acid multilayer modified membranes are characterized. The composite multilayer is resistant to protein adsorption and platelet adhesion and also prolongs clotting times, indicating that the blood compatibility is improved. Moreover, after clicking the small molecule anticoagulant alkynyl-citric acid onto the outermost of the zwitterionic multilayer, the membrane shows further improved anticoagulant property. The deposition of zwitterionic polymer and citric acid via click chemistry-enabled LBL assembly can improve the blood compatibility of the PSf membrane.

Boundary conditions for the maintenance of memory by PKMζ in neocortex (2009)

We report here that ZIP, a selective inhibitor of the atypical protein kinase C isoform PKMzeta, abolishes very long-term conditioned taste aversion (CTA) associations in the insular cortex of the behaving rat, at least 3 mo after encoding. The effect of ZIP is not replicated by a general serine/threonine protein kinase inhibitor that is relatively ineffective toward PKMzeta, is independent of the intensity of training and the perceptual quality of the taste saccharin (conditioned stimulus, CS), and does not affect the ability of the insular cortex to re-encode the same specific CTA association again. The memory trace is, however, insensitive to ZIP during or immediately after training. This implies that the experience-dependent cellular plasticity mechanism targeted by ZIP is established following a brief time window after encoding, consistent with the standard period of cellular consolidation, but then, once established, does not consolidate further to gain immunity to the amnesic agent. Hence, we conclude that PKMzeta is not involved in short-term CTA memory, but is a critical component of the cortical machinery that stores long- and very long-term CTA memories.
