Parameter extraction and modelling of the MOS transistor by an equivalent resistance

ABSTRACT During the analysis of multi-transistor circuits, the need arises to evaluate the time delay or the power consumption of the circuit. Due to the complexity of the transistor model, several complicated equations arise from which a compact-form solution cannot be obtained and a suitable physical insight cannot be drawn. With this regard, two contributions are presented in this paper. The first one is a fully analytical parameter extraction approach to be applied on the MOS transistors. The second one is a quantitative method for simplifying the analysis of MOS circuits by modelling the MOS transistor by a suitable equivalent resistance adopting the time-delay or the power-consumption equivalence criteria. The parameter-extraction method is verified by using the extracted parameters in the derived expressions according to the second contribution. Compared to other representations, the agreement of the proposed model with the simulation results is very good.
Message framing effects on food consumption: A social marketing perspective

Across two studies, this research examines the effects of positive versus negative framing of health messages on food consumption, in the relatively short and long run. Specifically, it studies the effects of multiple exposures to health messages over time (Study 1), using daily food consumption diary data. It replicates and extends those findings in a cross-sectional, single exposure setting to tease out the individual effects of positive and negative framing with consumption intentions as the dependent variable (Study 2). With this combination of an externally and internally valid setup, our research provides robust evidence of the associations of message effectiveness and behavioral outcomes. Our findings suggest that negative messages are more effective than positive messages in the short term but importantly, in the long term as well, suggesting that transforming consumption in the long term can be a viable social marketing objective with the appropriate message tactics.

Metal-Organic Frameworks in Oxidation Catalysis with Hydrogen Peroxide

In recent years, metal–organic frameworks (MOFs) have received increasing attention as selective oxidation catalysts and supports for their construction. In this short review paper, we survey recent findings concerning use of MOFs in heterogeneous liquid-phase selective oxidation catalysis with the green oxidant–aqueous hydrogen peroxide. MOFs having outstanding thermal and chemical stability, such as Cr(III)-based MIL-101, Ti(IV)-based MIL-125, Zr(IV)-based UiO-66(67), Zn(II)-based ZIF-8, and some others, will be in the main focus of this work. The effects of the metal nature and MOF structure on catalytic activity and oxidation selectivity are analyzed and the mechanisms of hydrogen peroxide activation are discussed. In some cases, we also make an attempt to analyze relationships between liquid-phase adsorption properties of MOFs and peculiarities of their catalytic performance. Attempts of using MOFs as supports for construction of single-site catalysts through their modification with heterometals will be also addressed in relation to the use of such catalysts for activation of H2O2. Special attention is given to the critical issues of catalyst stability and reusability. The scope and limitations of MOF catalysts in H2O2-based selective oxidation are discussed.
The Effects of Rice Husk Biochar Rate on Arbuscular Mycorrhizal Fungi and Growth of Soursop (Annona muricata L.) Seedlings

Soursop (Annona muricata L.) is increasingly planted in Malaysia for its agronomical importance as a multipurpose plant with medicinal and health benefits. However, there is limited information on soursop cultivation in Malaysia. Soursop can be inoculated with arbuscular mycorrhizal fungi (AMF) as a sustainable approach for successful seedlings growth before transplanting to field. As a beneficial symbiotic soil microorganism, AMF has been known as biofertilizer which can improve soil conditions and plant growth. Following the need to understand the soil management using soil beneficial microorganisms for soursop cultivation, this experiment aimed to determine the effects of AMF and biochar on the growth of soursop seedlings. The polybag experiment was conducted under glasshouse conditions at Farm 15, Faculty of Agriculture, UPM Serdang, Selangor. The study was arranged in Randomised Complete Block Design (RCBD) with eight treatments comprising different rates of rice husk biochar (RHB), with and without AMF and four replications. The treatments were; T1 (Control), T2 (AMF only), T3 (−AMF with 10 t/ha RHB), T4 (+AMF with 10 t/ha RHB), T5 (−AMF with 15 t/ha RHB), T6 (+AMF with 15 t/ha RHB), T7 (−AMF with 20 t/ha RHB) and T8 (+AMF with 20 t/ha RHB). Plant growth measurement were determined upon harvesting after four months of planting. Shoot and root biomass, leaf area meter, root surface area and root length were found significantly highest in soursop seedlings grown in soils amended with 10 t/ha RHB with or without AMF as compared to control. It was concluded that RHB, either individually or when in combination with AMF, had significantly improved the growth performance of soursop seedlings at nursery stage. Therefore, earliest inoculation of soursop seedlings with AMF at nursery stage could ensure successful mycorrhizal establishment and growth performance of soursop seedlings before transplanted under field condition.
Angiotensin II Type 1 Receptor Antibody-mediated Rejection Following Orthotopic Heart Transplant: A Single-center Experience

Supplemental Digital Content is available in the text. Background. Antibody-mediated rejection (AMR) following orthotopic heart transplant (OHT) causes significant morbidity and mortality. There are limited data on antibodies to the angiotensin II type 1 receptor antibody (AT1R-Ab) causing rejection following OHT. Methods. This is a retrospective, single-center study that presents our 2-y experience with a series of 11 patients with evidence of nonspecific graft dysfunction and pathologic levels of AT1R-Ab. The clinical outcomes and treatments were compared to a group of 10 patients, also with evidence of nonspecific graft dysfunction, but who had nonsignificant AT1R-Ab titers. Results. The mean age of the AT1R-Ab cohort was 52% and 73% were bridged to transplant with an left ventricular assist device. The average left ventricular ejection fraction at presentation was 45%, and most were not on an angiotensin receptor blocker (ARB). Endomyocardial biopsies in those with elevated AT1R-Ab levels frequently showed reactive endothelium/endocardium without C4d or intravascular CD68 staining. Ten patients (91%) were started on an ARB. Other therapies included plasmapheresis and IVIg (64%), with 4 patients also receiving rituximab. Most patients had symptom improvement, but minimal change in graft function at an average 6 mo of follow-up. Conclusions. The role of AT1R-Ab-mediated rejection in OHT recipients remains poorly understood. More than half of patients at our center who presented with graft dysfunction in the absence of acute cellular rejection or AMR were found to have elevated AT1R-Ab titers. Empiric AMR treatment in conjunction with ARB therapy may improve patient outcomes. Future studies are needed to better define the optimal treatment modalities for ATR1-Ab-mediated AMR.
Analysis of tumor mutation burden combined with immune infiltrates in endometrial cancer

Background Tumor mutational burden (TMB) is widely regarded as a predictor of response to immunotherapy. Few researchers have focused on the activity and prognosis of TMB in endometrial cancer (EC) and immune cells. Our study aimed to identify the prognostic role of TMB in EC. Methods We downloaded transcriptome data from The Cancer Genome Atlas (TCGA) database. Kaplan-Meier analysis with log-rank test was conducted to assess the difference in overall survival (OS) between the high and low TMB groups. The “CIBERSORT” scripts were performed to evaluate the immune compositions of EC patients. Cox regression analysis and survival analysis were used to verify the prognostic value prognosis of TMB. Results We obtained the single nucleotide mutation data for 529 EC patients. A missense mutation was the most common mutation type. TMB was associated with survival outcome, tumor grades, and pathological types. We identified 10 hub TMB-related signature and found that elevated T-cell subsets infiltrating density in the high TMB group revealed improved survival outcomes. According to Kaplan-Meier analysis, T cells gamma delta and T cells regulatory were prognostic immune cells in EC samples. Moreover, many top gene set enrichment analysis (GSEA) results, including amino sugar and nucleotide sugar metabolism, nucleotide excision repair, or p53 signaling pathway, were enriched significantly with TMB level as phenotype. Conclusions TMB is an important prognostic factor for EC, and TMB-related genes may be potential therapeutic targets for EC.
Advances in Tissue Engineering for Disc Repair

Intervertebral disc (IVD) degeneration is a leading cause of chronic low back pain (LBP) that results in serious disability and significant economic burden. IVD degeneration alters the disc structure and spine biomechanics, resulting in subsequent structural changes throughout the spine. Currently, treatments of chronic LBP due to IVD degeneration include conservative treatments, such as pain medication and physiotherapy, and surgical treatments, such as removal of herniated disc without or with spinal fusion. However, none of these treatments can completely restore a degenerated disc and its function. Thus, although the exact pathogenesis of disc degeneration remains unclear, there are studies examining the effectiveness of biological approaches, such as growth factor injection, gene therapy, and cell transplantation, in promoting IVD regeneration. Furthermore, tissue engineering using a combination of cell transplantation and biomaterials has emerged as a promising new approach for repair or restoration of degenerated discs. The main purpose of this review was to provide an overview of the current status of tissue engineering applications for IVD regenerative therapy by performing literature searches using PubMed. Significant advances in tissue engineering have opened the door to a new generation of regenerative therapies for the treatment of chronic discogenic LBP.
Dyeing Properties of Natural Dyes Extracted from the Junipers Leaves (J. excelsa Bieb. and J. oxycedrus L.)

ABCTRACT In this paper, two natural dyes were extracted from Junipers leaves (Juniperus oxycedrus L. and Juniperus excelsa Bieb.). Wool yarn (for carpet) was dyed with the extract using ferrous (II) sulfate, potassium dichromate and sodium sulfate as mordant. Then, CIELab (L*, a*, b*, c,* and h) values, color differences (ΔE) and color strength (K/S) values of dyed wool yarns were examined and the fastness properties of dyed wool against dry and wet rubbing were evaluated. According to the experimental results, the use of mordant increased the color strength of dye goods. All mordant increased the rub fastness of dyed samples such as similar scientific studies previously. Compared to two junipers, dyeing samples of J. excelsa are dyed darker than that of J. oxycedrus.
Explaining Ignoring: Working with Information that Nobody Uses

Research has demonstrated how ignorance is made, manipulated and called upon; how it is the result of strategies, activities and structures. This article extends the literature on ignorance by exploring actors’ own explanations of their self-inflicted ignorance following acts of ignoring. By means of a case analysis, we explore how actors explain and justify ignoring data they themselves produced. We provide a multifaceted model of how ignoring actors’ own rationales, facilitated by contextual conditions, enables persistent acts of ignoring the content and dysfunction of collectively upheld systems. We contribute to the understanding of ignorance by demonstrating how self-inflicted ignorance is made possible by the combination of ignoring rationales and their facilitators, which configures buffers against knowledge-seeking efforts.
Environmental Conditions Associated with Horizontal Convective Rolls, Cellular Convection, and No Organized Circulations

Typical environmental conditions associated with horizontal convective rolls (HCRs) and cellular convection have been known for over 50 years. Yet our ability to predict whether HCRs, cellular convection, or no discernable organized (null) circulation will occur within a well-mixed convective boundary layer based upon easily observed environmental variables has been limited. Herein, a large database of 50 cases each of HCR, cellular convection, and null events is created that includes observations of mean boundary layer wind and wind shear, boundary layer depth; surface observations of wind, temperature, and relative humidity; and estimates of surface sensible heat flux. Results from a multiclass linear discriminant analysis applied to these data indicate that environmental conditions can be useful in predicting whether HCRs, cellular convection, or no circulation occurs, with the analysis identifying the correct circulation type on 72% of the case days. This result is slightly better than using a mean convective boundary layer (CBL) wind speed of 6 m s−1 to discriminate between HCRs and cells. However, the mean CBL wind speed has no ability to further separate out cases with no CBL circulation. The key environmental variables suggested by the discriminant analysis are mean sensible heat flux, friction velocity, and the Obukhov length.
Anastrepha spp. (Diptera: Tephritidae) in Ximenia americana and other tropical fruits in a Brazilian savannah

The aim of this work was to evaluate the infestation of Anastrepha species in several fruit tree species and A. alveata in wild plum Ximenia americana L. (Olacaceae), as well as the fruit fly community in a Savannah area using faunal indexes and population fluctuation. For this, we installed McPhail traps and carried out collections at Palmeiras home garden, municipality of São Pedro of Piauí, state of Piaui, northeastern Brazil. We noted high infestation of A. alveata in wild plum, with 144.2 puparia/kg, 216.1 puparia/kg and 321.6 puparia/kg for the years 2014, 2015 and 2016 respectively. The infestation indexes of A. obliqua in red mombin (Spondias purpurea) were 146.1 puparia/kg in 2016 and 479.2 puparia/kg in 2017, and in umbu-hog plum (Spondias bahiensis) 607.3 puparia/kg in 2017, both from the Anacardiaceae family. The species that composed the fruit fly community were A. alveata, A. ethalea (predominant), A. obliqua, A. zenildae (dominant and accessory), A. sororcula and A. fraterculus (accidental). The population fluctuation of A. ethalea occurred from March to October, while A. alveata presented population peaks in the fruiting of wild plum, between October and December.
Protective effect of pomegranate peel extract on diabetic ocular structural changes in experimental diabetic rats: A histological, immunohistochemical and clinical study

Ocular complications of diabetes mellitus are rapidly progressing and have become a leading cause of vision impairment. The present study evaluated the potential protective role of pomegranate peel extract, as a powerful antioxidant agent, on the ocular complications of diabetes. One hundred, 8 weeks old, male Wistar rats were subdivided into three groups; the first control group (non-diabetic) was injected intraperitoneally with a single dose (2 ml/animal) of citrate buffer alone. The second group (diabetic untreated) was subjected to induction of diabetes by an intraperitoneal single dose of streptozotocin (60 mg/kg body weight). The third group (diabetic treated) was subjected to induction of diabetes as the second group and given simultaneously, 500 mg/kg body weight of pomegranate peel extract orally once per day with the drinking water. Clinical examination of lens and fundus was made, and the biochemical analysis was done at 8, 12, 16, 20, 24, 28, 32, 36 and 40 weeks after diabetes induction. At the end of the investigation (40 weeks), the rats were anesthetized, and the eyeballs were removed and sampled for histopathological, immunohistochemical, and ultrastructural investigations. The study revealed that the lens of 12 rats from a total of 40 rats of the second group (diabetic untreated) depicted the onset of cataract at 16 week, which increased gradually. The retina of the same group showed gradual inter-retinal microvascular abnormalities and histopathological changes. The third group (diabetic treated) showed marked amelioration as compared to the second group. ANOVA test for the biomedical indicators showed a statistically significant improvement in the third group. In conclusion, the pomegranate peel extract possesses strong potential for its development as a protective agent against ocular complications of diabetes.
Simulation of the Residual Stress of the Y2O3/Al2O3 Composite Deuterium Permeation Barrier under Thermal Shock

A deuterium permeation barrier is an essential part in the core component of nuclear reactors. It can protect the structure made of steel from being penetrated by deuterium in a fusion reactor. However, residual stress induced in the operation would dramatically influence the mechanical endurance of the coating, threatening the safety of the facilities. In this paper, finite element analysis was conducted to investigate the residual stress in nanoscale Al2O3 and Y2O3 coatings and their composites under thermal shock, from 700°C to 25°C. The max principal stress is assumed as the cause of crack initiation in the coating, because ceramics are brittle and fragile under tensile stress. Max shear stress and max Mises stress in the systems are also analyzed, and the effect of thickness in the range 100 nm to 1000 nm was investigated. The max principal stress in Al2O3 coating reaches its maximum value, 1.33 GPa, when the thickness of coating reaches 450 nm. And the max principal stress decreases at a very low rate as the thickness increases exceeding 450 nm. The max principal stress in Y2O3 coating increases rapidly as the thickness increases when the thickness of the coating is below 250 nm, and the max principal stress is at about 0.9 GPa when the thickness exceeds 500 nm. The max principal stress in the Y2O3/Al2O3 (150 nm) composite coating occurs in the Al2O3 layer and shows no difference from the single layer of 150 nm thick Al2O3 coating. The max principal stress site of all three kinds of coating is located at the edge of the coating 25 nm away from the interface. The result shows that residual thermal stress in the coating increases as the thickness increases when the thickness of the coating is below 200 nm due to the stress singularity of the interface. And as the thickness exceeds 500 nm, the increase in thickness has little impact on the residual thermal stress in the coating. Coating an Y2O3 top layer will not introduce any more residual thermal stress under the thermal shock condition. The Y2O3 coating causes much less residual stress under thermal shock compared with Al2O3 owing to its much lower Young’s modulus. The max principal stress in the 300 nm thick Y2O3 coating is 0.85 GPa while that of the Al2O3 coating is 1.16 GPa. The max residual stress of the composite Y2O3/Al2O3 (150 nm) coating is determined by the Al2O3 layer.
Lecture capture, social topology, and the spatial and temporal arrangements of UK universities

This article considers how technologies actively shape the topologies of UK higher education. Using the example of lecture capture systems, we examine the relationship between learning technologies and formations of space and time. Combining theories of sociomateriality and social topology, and concepts of assemblage and relationality, we expose the entanglement of interests that influence university spaces and times. Across 3 months coinciding with the onset of COVID-19 we collected over 500 tweets that discussed lecture capture within UK higher education, leading towards 2 central arguments. First, the topology of the lecture is fluid, and, even while being radically technologised, re-spatialised and disrupted, it persists as a lecture and a central pedagogical feature of university life. Second, lecture capture is a rich site of ‘issuefication’, and viewing learning technologies as dynamic issues enables a better understanding of how their meaning, function and influence are contingent on shifting and relational assemblages of human and non-human interests. Lecture capture can be pedagogical, commercial and political, thereby resisting deterministic framings of the relationship between technologies and the temporal and spatial arrangements of higher education.
Use of biological nano zinc as a feed additive in quail nutrition: biosynthesis, antimicrobial activity and its effect on growth, feed utilisation, blood metabolites and intestinal microbiota

Abstract A total of 200 1-week-old Japanese quails were randomly allocated into five treatment groups, each consisting of 40 unsexed birds (five replicates, eight birds each). Quails were reared in traditional cages (90 × 40 × 40 cm), and feed and water were made available throughout the 5-week trial. The treatment groups were as follows: the 1st was fed basal diet, whereas the 2nd, 3rd, 4th, and 5th groups were fed with ration supplemented with nano zinc (Zn-NPs) at doses of 0.1, 0.2, 0.3, and 0.4 g/kg diet, respectively. Results showed that, a significant (p ≤ .0001) improvement in body weight, weight gain, feed intake, and feed conversion ratio was observed in birds fed diets supplemented with 0.2 g/kg of Zn-NPs. Supplementation of Zn-NPs at doses of 0.1–0.3 g/kg diet demonstrated a positive impact on the activity of ALT, AST, and LDH. The liver profile parameters were not statistically influenced (p > .05) by dietary biological nano zinc, with the exception of total cholesterol (TC), high density lipoprotein (HDL), and low density lipoprotein (LDL). Also, dietary supplementation of biological Zn-NPs at concentrations of 0.1–0.3 g/kg diet demonstrated a positive impact on superoxide dismutase (SOD), glutathione peroxidase (GPX), malondialdehyde (MDA), immunoglobulin G (IgG), and immunoglobulin M (IgM). Dietary supplementation of Zn-NPs led to an increase in beneficial microbial populations. From the obtained results, Zn-NPs supplementation at 0.2 g/kg diet had a positive effect on the performance and physiological status of growing Japanese quails. HIGHLIGHTS Zinc (Zn) is an important trace element for the general functioning of the animal body. A significant improvement in growth performance was observed in birds fed diet enriched with 0.2 g/kg of Zn-NPs. Supplementation of Zn-NPs (0.1–0.3 g/kg diet) demonstrated a positive impact on immunity and antioxidant indices
Sensitive Skins May Be Neuropathic Disorders: Lessons from Studies on Skin and Other Organs

Sensitive skin can be considered a neuropathic disorder. Sensory disorders and the decrease in intra-epidermal nerve ending density are strong arguments for small-fiber neuropathies. Sensitive skin is frequently associated with irritable bowel syndrome or sensitive eyes, which are also considered neuropathic disorders. Consequently, in vitro co-cultures of skin and neurons are adequate models for sensitive skin.
