SPICE Compact BJT, MOSFET, and JFET Models for ICs Simulation in the Wide Temperature Range (From −200 °C to +300 °C)

The temperature range of SPICE models of bipolar and field-effect transistors is extended from the standard commercial level (<inline-formula> <tex-math notation="LaTeX">$-60\,\,^\circ {\mathrm{ C}}\cdots +150\,\,^\circ \text{C}$ </tex-math></inline-formula>) to harsh conditions level (<inline-formula> <tex-math notation="LaTeX">$-200\,\,^\circ {\mathrm{ C}}\cdots +300\,\,^\circ \text{C}$ </tex-math></inline-formula>) for low/high-temperature ICs design. This is done by including additional equations for temperature-dependent parameters, and by connecting additional elements to the device equivalent circuit to take into account the thermal effects. The universal automated methodology of model parameters extraction from the experimental data measured at low and high temperatures is proposed. The good agreement between simulated and measured device characteristics is achieved. The RMS error is not more than 10%–20%.
Geophysical Prospecting for Geothermal Resources in the South of the Duero Basin (Spain)

The geothermal resources in Spain have been a source of deep research in recent years and are, in general, well-defined. However, there are some areas where the records from the National Institute for Geology and Mining show thermal activity from different sources despite no geothermal resources being registered there. This is the case of the area in the south of the Duero basin where this research was carried out. Seizing the opportunity of a deep borehole being drilled in the location, some geophysical resources were used to gather information about the geothermal properties of the area. The employed geophysical methods were time-domain electromagnetics (TDEM) and borehole logging; the first provided information about the depth of the bedrock and the general geological structure, whereas the second one gave more detail on the geological composition of the different layers and a temperature record across the whole sounding. The results allowed us to establish the geothermal gradient of the area and to discern the depth of the bedrock. Using the first 200 m of the borehole logging, the thermal conductivity of the ground for shallow geothermal systems was estimated.
Static and Cyclic Performance of Repaired Reinforced Concrete Beams Using a Range of Underlays

The repair and strengthening of concrete structures has become a significant area of specialization in the construction industry, in many countries the cost of repair and strengthening is accounting for nearly 50% of the overall expenditure within the construction industry. Generally, concrete properly made and compacted has a high resistance against deterioration and possible damage. However, structures may suffer damage or deterioration from a variety of internal and external causes. Repair may carried out to protect the reinforcement, to restore the structure to its original strength, or merely to restore the original appearance. Whatever the reason, an essential requirement is that the repair achieves a satisfactory bond with the substrate concrete and maintains good adhesion and protection over the service life of the structure. A range of repair of repair materials and techniques are available to the maintenance engineer, the selection of the best suitable materials and most effective technique are essential in a durable and effective technique. In this investigation, three types of materials used representing the full range of repair materials available, namely, a basic cementitious, a polymer modified cementious and an epoxy render. Twelve reinforced concrete beams, with preformed faults, were repaired and tested under three loading systems, a static loading, a service level cyclic loading and a near ultimate fatigue loading, the results from these beams were compared to control beams with similar reinforcement and made from similar concrete, but with no faults. 
Effect of Molasses and Fermented Juice of Epiphytic Lactic Acid Bacteria on the Fermentation Characteristics and Nutrient Compositions of Cassava Leaves Silage

| Molasses and fermented juice of epiphytic lactic acid bacteria (FJLB) addition improved the quality of cassava leaves silage; however their effect depends on the types of forages ensiled. Thus, this study was aimed to compare the effect of molasses and FJLB additives on the fermentation characteristics and nutrient compositions of cassava leaves silage. Cassava leaves were chopped into pieces of 1-2 cm length before ensiling. The molasses 5% (w/w) and FJLB 1% (v/w) of fresh material were added as silage additives. As the measurement, the physical characteristics, chemical compositions, nutritive values, organic acid concentrations, lactic acid bacteria (LAB) count, volatile based nitrogen (VBN) and V-score of experimental silages were determined. In general, the physical characteristics and nutritive values of molasses and FJLB silages were not significantly different (p>0.05), however crude protein and fibre contents of FJLB silage were significantly higher (p<0.05) than molasses silage. Inversely, total carbohydrate and non fibre carbohydrate contents of molasses silage were also greater (p<0.05) than FJLB silage, resulted the higher feed intake in molasses silage. The acetic acid and propionic acid concentrations were greater (p<0.05) in molasses silage, whereas the higher (p<0.05) LAB count was found in FJLB silage. Regarding the indicators for good quality silage, VBN and V-score, both FJLB and molasses silages possessed the parameters for good quality silages. Thus, this experiment indicated that FJLB can be alternatively used as additive instead of using molasses in cassava leaves silage.

Heat-Assisted Magnetic Recording on Dual Structure Bit Patterned Media

Heat-assisted magnetic recording on bit patterned media dots with two magnetic structures is modeled. If the magnetic structures have different Curie temperatures two bits of information can be stored in each dot by writing at high and low temperatures. The areal density capability of the dual structure media was calculated and found to be in excess of 7 Tbit/in2, even when taking account of dot position distributions and magnetostatic fields from surrounding dots.
A Systematic Review on the Effect of Use of Impregnated Retraction Cords on Gingiva

Introduction: For teeth requiring crowns or replacement in the form of fixed dental prosthesis, gingival retraction becomes a mandatory procedure which aids in recording the prepared and unprepared surfaces of the abutment tooth. Various methods of retraction known in the past include mechanical (copper band, retraction cord packing, rubber dam placement), chemical and chemo mechanical (retraction cords soaked in racemic epinephrine, dl – aluminium sulfate, aluminium chloride, adrenaline hydrochloride and cordless paste – expasyl and expanding polyvinyl siloxane material) , rotary (gingettage, electro rotary) and laser. Though many new techniques have come up, by far, chemo-mechanical retraction of gingiva is widely preferred. Impregnated gingival retraction cords are known to efficiently perform retraction of the gingiva along with hemostasis. Objective: This systematic review is performed to assess the effects of gingival retraction done by cords impregnated with various chemicals on gingival health. Methods: Search Strategy: The data bases of Pubmed Central and Medline were searched for the related topics. Bibliographies of randomized control trials and reviews, identified in the electronic search, were analyzed for studies published outside the electronically searched journals. Results: The systematic search yielded 4 articles and one article was rejected on the basis of irrelevance of title and abstract. One article was excluded after examination of the core data, 2 articles were handpicked and a total of 4 articles were obtained based on the inclusion criteria. Conclusion: From all the articles considered in this review, we may conclude saying that knitted cords impregnated with aluminium chloride and potassium aluminium sulphate are more preferable than the rest.
Effects of nanoparticles loaded with Chaetomium globosum KMITL-NO805 extracts against leaf spot of rice Var. Sen Pidoa

Nano-CGH, nano-CGE, and nano-CGM from Chaetomium globosum KMITL-N0805 expressed antifungal activity (ED50 values of 1.21, 1.19, and 1.93ppm/mL, respectively) against Curvularia lunata, the causal agent of leaf spot disease of rice var. Sen Pidoa. It was demonstrated that these nanoparticles caused the disruption and distortion of the pathogen cells, leading to their loss of pathogenicity. Tests in a pot experiment showed that nano-CGH, nano-CGE, and nano-CGM could significantly control leaf spot of rice var. Sen Pidoa. Based on the disease severity index at 60 days after treatment, nano-CGH and nano- CGM resulted in higher disease reduction (61.54%) than nano-CGE (53.83%). From these findings, it can be concluded that nano-CGH, nano-CGE, and nano-CGM have the ability to decrease leaf spot disease of rice var. Sen Pidoa caused by C.lunata. Moreover, the research showed that all three types of nanoparticles significantly increased the height and number of tillers of the rice plant relative to the non-treated control.
Influence of Preparation and Isolation Methods on the Measurement of Calcium Levels in Dried Freshwater Shrimp (Macrobrachium sp.)

In Indonesia, shrimp are an important natural resource. They are easily obtained and are assumed to contain high levels of calcium. This research aims to determine the calcium levels in Macrobrachium sp. as well as the effects of preparation and isolation methods on such measurements. Ebi shrimp were divided into two preparation groups: oven-dried and nonheated. Oven drying was performed at 80°C for 20 min. The samples in each preparation group were divided according to three isolation methods: dilution, acid digestion, and dry ashing. In the dilution method, a sample was shaken in demineralized water. The acid digestion method used microwave-assisted digestion with nitric acid and hydrogen peroxide. In the dry ashing method, a sample was heated from 26°C to 550°C to produce ash before nitric acid and hydrochloric acid were added. Measurements were performed using atomic absorption spectrometry and an ion-selective electrode. The results showed that the highest calcium levels were obtained by acid digestion isolation: 7749 ppm (oven-dried) and 8853 ppm (nonheated). There were differences in the calcium level between the preparation methods and among the isolation methods. The preparation methods were found to have a strong correlation with calcium level measurement (r2 = 0.878, p < 0.05).
Activation of polarized cell growth by inhibition of cell polarity

A key feature of cells is the capacity to activate new functional polarized domains contemporaneously to pre-existing ones. How cells accomplish this is not clear. Here, we show that in fission yeast inhibition of cell polarity at pre-existing domains of polarized cell growth is required to activate new growth. This inhibition is mediated by the ERM-related polarity factor Tea3, which antagonizes the activation of the Rho-GTPase Cdc42 by its co-factor Scd2. We demonstrate that Tea3 acts in a phosphorylation-dependent manner controlled by the PAK kinase Shk1 and that, like Scd2, Tea3 is direct substrate of Shk1. Importantly, we show that Tea3 and Scd2 compete for their binding to Shk1, indicating that their biochemical competition for Shk1 underpins their antagonistic roles in controlling polarity. Thus, by preventing pre-existing growth domains from becoming overpowering, Tea3 allows cells to redistribute their polarity-activating machinery to prospective sites and control their timing of activation.

portuguesOs objetivos deste trabalho foram verificar se ha variabilidade genetica e avaliar as relacoes lineares entre a arquitetura de planta e a produtividade de graos de milho. Foram conduzidos tres experimentos no delineamento blocos completos ao acaso. Em 51 cultivares, foram avaliados caracteres relacionados ao numero de folhas, as alturas de planta e de espiga, ao ângulo foliar, ao comprimento da folha, a largura da folha, a area foliar e a produtividade de graos, totalizando 22 caracteres. Foram realizadas analises de variância individuais, verificados os pressupostos de normalidade dos erros e homogeneidade de variâncias residuais e agrupadas as medias de cultivares pelo teste de Scott-Knott. Foi determinada a matriz de correlacao fenotipica entre os 22 caracteres das 51 cultivares. Ha variabilidade genetica entre as cultivares em relacao ao numero de folhas, alturas de planta e de espiga, ângulo foliar, comprimento da folha, largura da folha, area foliar e produtividade de graos. Folhas localizadas proximas a espiga apresentam menor ângulo foliar e maiores comprimento da folha, largura da folha e area foliar. O ângulo foliar aumenta gradativamente em direcao as folhas da extremidade inferior e superior da planta. O comprimento da folha, a largura da folha e a area foliar diminuem gradativamente em direcao as folhas da extremidade inferior e superior da planta. Cultivares com maior numero de folhas e maior area foliar estao associadas a plantas com maior produtividade de graos EnglishThe objectives of this study were to analyze whether there is genetic variability and assess the linear relationships between plant architecture and maize grain yield. Three experiments were carried out in a complete randomized block design. A group of 51 cultivars was assessed in relation to 22 traits: number of leaves, plant height, ear height, leaf angle, leaf length, leaf width, leaf area, and grain yield. Individual analyses of variance were performed, the assumptions of normality of errors and homogeneity of residual variances were tested, and means were grouped by the Scott-Knott test. The phenotypic correlation matrix was constructed using the 22 traits of the 51 cultivars. Results showed that there is genetic variability among cultivars for number of leaves, plant height, ear height, leaf angle, leaf length, leaf width, leaf area, and grain yield. Leaves close to the ear have smaller leaf angle and larger length, width, and area of the leaves. Leaf angle gradually increases towards the lower and upper ends of the plant. Length, width, and area gradually decreases in leaves towards the lower and upper ends of the plant. Cultivars with higher number of leaves and larger leaf area are associated with higher grain yield
The buoyant cell density of Cryptococcus neoformans is affected by capsule size

Cryptococcus neoformans is an environmental pathogenic fungus with a worldwide geographical distribution that is responsible for hundreds of thousands human cryptococcosis cases each year. During infection, the yeast undergoes a morphological transformation involving capsular enlargement that increases microbial volume. To understand the factors that play a role in environmental dispersal of C. neoformans and C. gatii we evaluated the buoyant cell density of Cryptococcus using Percoll isopycnic gradients. We found differences in the buoyant cell density of strains belonging to C. neoformans and C. gatti species complexes. The buoyant cell density of C. neoformans strains varied depending on growth medium conditions. In minimal medium, the cryptococcal capsule made a major contribution to the buoyant cell density such that cells with larger capsules had lower density than those with smaller capsules. Removing the capsule, both by chemical or mechanical methods, decreased the C. neoformans cell density. Melanization of the C. neoformans cell wall, which also contributes to virulence, produced a small but consistent increase in cell density. C. neoformans sedimented much slower in seawater as its density approached the density of water. Our results suggest a new function for the capsule whereby it can function as a flotation device to facilitate transport and dispersion in aqueous fluids.
Faraway, Not So Close: The Conditions That Hindered Knowledge Sharing and Open Innovation in an Online Business Social Network

This article explains the main mechanisms influencing the knowledge collaboration dynamics occurring across an online business community. Prior research study had conceived firms as autonomous entities competing against each other to reach the competitive advantage. Nonetheless, online business social networks (BSNs) can be seen as networks of organizations that interact within digital structures, providing an optimal locus to foster external knowledge flows, enabling participants to share knowledge across organizational boundaries, and eventually leading to open innovation outcomes. We analyze how virtual networks of business relationships influence the form of knowledge collaboration firms can be engaged in. We analyze the entire three-year collaborative history of a BSN. After a promising launch of the BSN, it declined and failed. By analyzing front- and backstage combined with organizational and technological features of the online business community, we identify and discuss five categories of mechanisms affecting the knowledge collaboration over time and reducing the firms’ uncertainty in exchanging information: first, orchestrators’ skills and competencies in running the online platform; second, internal firm capabilities allocating proper organizational resources; third, usability of the digital platform; four, interconnections between frontstage and backstage combined with technological and organizational features; and fifth, perceived virtual copresence.
Microsphères résorbables pour embolisation et chimio embolisation

L’embolisation therapeutique est devenu le traitement de choix pour l’hemorragie, les malformations arterioveneuses ou certains types de cancer. Parmi differents agents d’embolisation,les microspheres non degradables (Embozene®, Bead BlockTM,…) sont les plus utilisees. Leur forme bien spherique et leur taille calibree permettent un meilleur ciblage dans les vaisseaux et une bonne qualite de l’occlusion. Dans certains cas cliniques, l’embolisation temporaire, envisageable avec l’utilisation des microspheres resorbables peut etre benefique pour les patients. Le but du travail realise au cours de cette these a ete le developpement de microspheres resorbables satisfaisant les differents criteres pour etre employees comme materiaux d’embolisation (taille calibree,biocompatibles, elastique pour etre injectee au travers des catheters mais suffisamment rigide pour resister a la pression sanguine). Dans cet objectif, nous avons developpe une methode de synthese de microspheres constituees d’hydrogels hydrolysables par polymerisation en suspension. Une large gamme de microspheres ont ete synthetisees en modulant la nature du reticulant et/ou la composition des milieux de polymerisation. Les experiences in vitro ont demontre que les microspheres obtenues sont satisfaisantes pour permettre leur injection au travers des catheters. La degradation rapide des ponts de reticulation a ete confirmee a travers la diminution du module elastique G’ et du pH du surnageant, accompagnee d’une augmentation du taux de gonflement.Malgre une degradation partielle des microspheres (due a une reaction secondaire formant des liaisons de reticulation non degradables), le temps de l’hydrolyse a repondu parfaitement au cahier de charges (entre 7 et 49 jours). Des etudes complementaires pour optimiser la reaction de polymerisation vont permettre le developpement de microspheres totalement degradables.
Information Weighting Under Least Squares Learning

This paper evaluates how adaptive learning agents weight different pieces of information when forming expectations with a recursive least squares algorithm. The analysis is based on a renewed and more general non-recursive representation of the learning algorithm, namely, a penalized weighted least squares estimator, where a penalty term accounts for the effects of the learning initials. The paper then draws behavioral implications of alternative specifications of the learning mechanism, such as the cases with decreasing, constant, regime-switching, adaptive, and age-dependent gains, as well as practical recommendations on their computation. One key new finding is that without a proper account for the uncertainty about the learning initial, a constant-gain can generate a time-varying profile of weights given to past observations, particularly distorting the estimation and behavioral interpretation of this mechanism in small samples of data. In fact, simulations and empirical estimation of a Phillips curve model with learning indicate that this particular misspecification of the initials can lead to estimates where inflation rates are less responsive to expectations and output gaps than in reality, or “flatter” Phillips curves.
Psychometric Properties of the Experiences in Close Relationship Scale (Short Form) with Pakistani Adolescents

Objective: Despite the increased interest globally in youth mental health, there is a lack of culturally-adapted psychometric measures for use with adolescents within the South Asian context in general, and Pakistan specifically. To address this gap one of the most efficient and cost effective methodological developments is to translate and validate psychometrically sound measures rather than developing indigenous scales. Method: This study validated the Experiences in Close Relationship Scale-12 (ECR-12), in a sample of Pakistani adolescents, using an Urdu translation. The ECR-12, Relationship Questionnaire (RQ), the Rosenberg`s Self-Esteem Scale (RSES), and the Hospital Anxiety and Depression Scale (HADS) were administered to 400 adolescents aged 12-18 years from three schools in Rawalpindi, Pakistan. Cronbach’s alphas, confirmatory factor analysis (CFA) and correlations were assessed. Results: High Cronbach-alphas across scales illustrated good reliability. A 2-factor model for the ECR-12 emerged, with adequate goodness-of-fit after removing the influence of response sets using method factors. ECR-12 showed factor specific significant associations with RQ attachment patterns, establishing both convergent and discriminant validity. Positive associations between ECR-12 and HADS scores, and ECR-12`s negative association with RSES scores demonstrate construct validity. Conclusion: This psychometric validation study demonstrates utility of the Urdu translation of the ECR-12 for youth mental health research in transcultural settings.
