High‐temperature H2 anneal of interface defects in electron‐beam‐irradiated MNOS structures

A thermal anneal technique is proposed to effectively remove electron beam irradiation damage in metal‐nitride‐oxide semiconductor structures. Using a high‐temperature (800–950 °C) H2 anneal treatment the SiO2 layer is impregnated with hydrogen after the nitride deposition. This leads to very low surface state densities for both thick‐oxide and thin‐oxide devices. After irradiation the device is given a mild heat treatment at 450 °C in an inert ambient. A complete removal of the radiation‐induced fixed charges and surfaces states is observed. The effectiveness of the high‐temperature H2 anneal is most pronounced for thin‐oxide MNOS structures. The technique is shown also to be effective in case of other types of ionizing radiation.
Szemerédi-type clustering of peer-to-peer streaming system

In this work we made a preliminary clustering analysis of an experimental peer-to-peer system, tested in a small scale experiments within PlanetLab. The application was an Internet-TV like streaming system based on Chord architecture. Our clustering is inspired by the Szemeredi's Regularity Lemma (SzRL). Such approach was already demonstrated in biology and appeared to be a powerful tool. Szemeredi's result suggests that the nodes of a large enough graph can be partitioned in few clusters in such a way that link distribution between most of the pairs look like random. Our main goal is to study what can this type of clustering tell us about p2p systems using our experimental system as source of data. We searched clusterings of Szemeredi-type by using max likelihood as guidance. Our graph is directed and weighted. The link direction indicates a client-server relation and the value is the proportion of all chunks obtained from such a link during the whole experiment. We think that the preliminary results are interesting. Most of the cluster pairs have very distinguished patterns of link distribution, indicating that such a novel approach has potential in classifying peers effectively. The values of weights between clusters and their distribution show some apparent patterns. We end up with 9 cluster pairs. Contributions: practical implementations of streaming system by V. P. and analysis by H. R.
Practitioner Experiences with Domestic and Family Violence in COVID‐19

The advent of COVID‐19 as a global public health crisis in 2020 was quickly followed by predictions regarding likely increases in occurrences of domestic and family violence (DFV). The aim of this study was to understand the impact of the pandemic on practitioner experiences of DFV in one service organisation in New South Wales, Australia. Qualitative focus group interviews were performed with senior practitioners at Relationships Australia (NSW), and a grounded theory approach was employed in formulation of a perspective which highlighted social isolation under public health management social distancing measures as that which distinguished practitioner experiences of DFV during COVID‐19. Social isolation was conceived as the overarching factor across categorisations of practitioner responses, including: (a) situations of client domestic relations; (b) client general life circumstances; (c) emerging client self‐awareness; (d) organisational and social systems changes; and (e) necessary work practice changes. Organisational and workplace recommendations address the relative difference of pandemic management measures from natural disaster occurrences, with respect to supporting people experiencing DFV.
Far‐infrared step‐tunable coherent radiation source: 70 μm to 2 mm

Noncollinear mixing of radiation from CO2 TEA lasers has been used to generate phase‐matched far‐infrared difference‐frequency radiation in GaAs. The wavelength of the far‐infrared radiation was tuned from [inverted lazy s] 70 μm to 2 mm in small steps by selecting the frequencies of the two CO2 lasers by means of intracavity diffraction gratings. A theoretical analysis of the two‐dimensional phase matching is presented.
Peptic Ulcer Disease Associated with Central Obesity

This retrospective cross-sectional study aimed to evaluate associations between peptic ulcer disease (PUD), bone mineral density, and metabolic syndrome (MetS) and its components in healthy populations. Data were collected from the health examination database of a tertiary medical center in southern Taiwan from January 2015 to December 2016. Subjects who had undergone metabolic factors assessment, upper gastrointestinal endoscopy, and dual energy X-ray absorptiometry scans were enrolled. In total, 5102 subjects were included, with mean age 52.4 ± 12.0 years. Among them, 1332 (26.1%) had PUD. Multivariate logistic regression analysis showed that age (OR 1.03, p < 0.001), male (OR 1.89, p < 0.001), diabetes (OR 1.23, p = 0.004), BMI (OR 1.03, p = 0.001), and GOT (OR 1, p = 0.003) are risk factors for PUD. Regarding MetS parameters, larger waist circumference (OR 1.26, p = 0.001) is associated with PUD, and high triglycerides (OR 1.20, 95% CI 1.01–1.43) is associated with gastric ulcer, while low HDL (OR 1.31, 95% CI 1.07–1.59) and osteoporosis (OR 1.44, 95% CI 1.08–1.91) are associated with duodenal ulcer. In conclusion, central obesity is associated with PUD in a middle-aged healthy population. Subjects with high triglycerides are prone to gastric ulcers, and those with osteoporosis and low HDL are prone to duodenal ulcers.

The Effect of BMI on Blood Lipids and Dyslipidemia in Lactating Women

Background: This study aimed to explore the correlation between body mass index (BMI) and dyslipidemia and the optimal cut-off point for BMI to distinguish the risk of dyslipidemia in lactating women. Methods: A total of 2295 lactating women subjects were included in this study, all within 2 years postpartum. All samples were from “China Children and Lactating Mothers Nutritional Health Surveillance (2016–2017)”. BMI, blood lipids, demographic information, lifestyle habits, and other serum indicators were obtained in this survey. Generalized linear model, logistic regression, restricted cubic spline (RCS) and ROC curve analysis were used to evaluate the relationship among BMI, blood lipids, and dyslipidemia. Results: BMI in lactating women was positively correlated with total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), but negatively correlated with high-density lipoproteincholesterol (HDL-C) (p < 0.05). Higher BMI in lactating women was associated with higher ORs of dyslipidemia (hypercholesterolemia, hypertriglyceridemia, high-LDL-cholesterolemia, low HDL-cholesterolemia) (p < 0.05). These associations were stable across age groups, breastfeeding child age (months), parity, physical activity level, fasting plasma glucose (FPG), and hemoglobin. These factors did not interact with this relationship (p > 0.05). The optimal cut-off point for BMI was 24.85 kg/m2 determined by using ROC analysis, which can distinguish the risk of dyslipidemia. Conclusions: BMI was positively correlated with risk of dyslipidemia. Maintaining an ideal weight may prevent dyslipidemia in lactating women, and BMI is recommended to be controlled below 24.85 kg/m2.
Percolation threshold and electrical conductivity of graphene-based nanocomposites with filler agglomeration and interfacial tunneling

The dispersion state or degree of agglomeration of graphene is known to have a significant influence on the percolation threshold and electrical conductivity of graphene-based polymer nanocomposites. In addition, an imperfectly conducting interface and tunneling-assisted interfacial conductivity can also affect the overall conductivity. In this paper, a continuum theory is developed that considers all these factors. We first present a two-scale composite model consisting of graphene-rich regions serving as the agglomerates and a graphene-poor region as the matrix. We then introduce the effective-medium theory to determine the percolation threshold and electrical conductivity of the agglomerate and the composite. To account for the effect of imperfect interfaces, a thin layer of interphase with low conductivity is introduced to build a thinly coated graphene, while to account for the contribution of electron hopping from one graphene to another, Cauchy's statistical function which can reflect the increased.
Novel Experimental Setup for Coulometric Signal Transduction of Ion-Selective Electrodes

In this work, a novel and versatile experimental setup for coulometric signal transduction of ion-selective electrodes (ISEs) is introduced and studied. It is based on a constant potential coulometric measurement carried out using a one-compartment three-electrode electrochemical cell. In the setup, a potassium ion-selective electrode (K+- ISE) is connected as the reference electrode (RE). A poly(3,4-ethylenedioxythiophene) doped with polystyrene sulfonate (PEDOT:PSS)-based electrode with a dummy membrane (DM) and a glassy carbon (GC) rod are connected as the working electrode (WE) and counter electrode (CE), respectively. Adding a non-selective dummy membrane to the structure of the WE facilitates the regulation of the measured signal and response time. The results from electrochemical impedance spectroscopy measurements carried out on the WE showed that the time constant is profoundly influenced by the dummy membrane thickness. In addition, the redox capacitance of the PEDOT:PSS film shows a better correlation with the electrode area than the film thickness. Sequential addition/dilution experiments showed the improvement of current and cumulated charge signals in the new setup studied in this work compared to the setup used in the original coulometric signal transduction method. Both conventional ISEs and solid-contact ISEs (SCISEs) were used in this work. The results showed that the coulometric response was independent of the type of ISE used as RE, confirming the versatility of the novel set-up.
Prevalence of High Blood Pressure in Pediatric Patients with Sleep-Disordered Breathing, Reversibility after Treatment: The KIDS TRIAL Study Protocol

Current data support an increase in the prevalence of high blood pressure (HBP) in pediatric patients with sleep-disordered breathing (SDB). Adeno-tonsillectomy has been shown to be an effective treatment for most patients. Our objective was to determine the prevalence of HBP in pediatric patients with SDB and the impact of adeno-tonsillectomy with a multicenter, longitudinal, and prospective study that included 286 children referred for suspected SDB. The diagnosis of SDB was established by polysomnography (PSG) and the diagnosis of HBP by 24-h ambulatory blood pressure monitoring (ABPM). In patients without SDB and SDB without treatment indication, these tests were repeated six months after the baseline visit. For patients with medical treatment for SDB, the tests were repeated six months after the treatment initiation. Finally, in patients with surgery indication, ABPM was performed just before surgical treatment and ABPM and PSG six months after the intervention. The study contributes to elucidating the association between SDB and HBP in pediatric patients. Moreover, it contributes to determining if intervention with adeno-tonsillectomy is associated with BP reduction. The results have direct implications for the management of SDB, providing essential information on treatment indications for existing clinical guidelines. NCT03696654.
A New Biotin Labeling and High-Molecular-Weight RNA Northern Method and Its Application in Viral RNA Detection

Viruses cause severe crop losses. Studying the interaction between viruses and plants is very important for development of control measures. Northern blot is a well-accepted but very challenging technique to monitor the infection of viruses. Here, we modified the high-molecular-weight (hmw)RNA Northern blot experiment process, utilizing vertical electrophoresis to separate the RNA with denatured agarose gel. This protocol is compatible with regular equipment for Western blots and small RNA Northern blots and requires less input of total RNA. A new method to label the probe with biotin was also developed, which requires commonly used T4 DNA polymerase and detects viral RNA with high sensitivity. These new protocols made hmwRNA Northern blot cost-effective and easy-to-operate, very suitable for studying virus–host interactions.
The Prevalence of Ocular Extra-Intestinal Manifestations in Adults Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis

Patients with inflammatory bowel disease (IBD) have a greater frequency of ocular extra-intestinal manifestations (O-EIMs) than the general population, while Crohn’s disease (CD) and ulcerative colitis (UC) have inconsistent prevalence, according to previous studies. This study aimed to examine the prevalence of O-EIMs in CD and UC, respectively. We systemically reviewed O-EIMs and IBD across several online databases. Inclusion criteria are as follows: (1) observational studies examining the association between O-EIMs and IBD, such as cross-sectional, case–control, or cohort studies; (2) human and adult individuals; and (3) with case and control groups consisting of patients with and without O-EIMs, respectively. Patients under the age of 18 or any study on pediatric IBD will be excluded. The prevalence of uveitis in adults was determined by 21 studies comprising 190,941 individuals with IBD, including 62,874 CD and 128,067 UC. The pooled analysis revealed significantly increased odds of uveitis in patients with CD than with UC (pooled odd ratio (OR) 1.603, 95% confidence interval 1.254–2.049). The subgroup analysis revealed that European populations had significantly higher odds of developing uveitis and episcleritis in patients with CD than UC (pooled OR 1.683 and 2.401, respectively). Although O-EIMs may be the prodrome of IBD, no consistent finding was obtained as a result of the high heterogeneity from the two included studies. This meta-analysis indicates the significantly increased odds of uveitis in adults with CD than those with UC. In subgroup analysis, European with CD seemed to have higher odds of uveitis and episcleritis than those with UC. Nonetheless, the link between O-EIMs and IBD remained unclear.
Evaluation of the Carotenoids Profile from Annona muricata and Protective Effects Against Copper Accumulation: Wilson’s Disease

Abstract Wilson’s disease is characterized by the accumulation of copper (Cu) in the body and does not have a curative treatment, having a high rate of patients who abandon the use of treatment drugs. Thus, there is a need to use raw materials from natural and easily accessible sources, which mitigates the consequences of the disease and provides beneficial adjuvant effects. Medicinal plants are part of this context, Annona muricata, better known as soursop, has a widespread use all around the world. In the present study, the carotenoid profile from leaves of the plant was assessed by high performance liquid chromatography coupled with a photodiode array and mass spectrometry detectors. In parallel the bioactivity of carotenoid extract was evaluated. The cytotoxicity of the aerial parts of the plant was evaluated through the MTT assay, as well as the IC50 of the treatments with copper in cell lines 293T, BV-2, and RAW 264.7. The anti-inflammatory activity and production of nitric oxide induced by lipopolysaccharide (LPS) were also evaluated. A total of nine carotenoids were separated in Annona muricata, with lutein being the major one 72.87%. A. muricata showed important antioxidant, cytoprotective, and anti-inflammatory activity in in vitro model of Wilson’s disease. Finally, it can be concluded that A. muricata proves to be a potential candidate for future studies for therapeutic alternatives of chronic diseases. GRAPHICAL ABSTRACT
Peripheral Neuropathy in Beta-Thalassemia: Corneal Confocal Microscopy-Based Study

Background Peripheral neuropathy is a controversial but serious complication of beta-thalassemia (β-Th). Although few studies have reported no relationship between neuropathy and thalassemia, many have linked it with increasing age, iron overload, and iron chelator toxicity. This study aims to investigate the presence of neuropathy in β-Th using corneal nerve fibers. Methodology A cross-sectional study was conducted using corneal confocal microscopy on individuals with intermediate and major β-Th who were compared to healthy individuals. The main outcome variables were corneal main nerve and branch nerve densities which were calculated using Image J software. The comparison between groups was done using the independent-samples F-test and Bonferroni post-hoc analysis. Results There was reduced corneal main nerve and branch nerve density in β-Th intermediate and major patients compared to the control group, and the results were statistically significant (p-value <0.05). However, a significant correlation was not observed between serum ferritin levels and corneal nerve parameters. Conclusions The reduction in corneal nerve parameters in β-Th patients compared to healthy controls can be an indication of peripheral neuropathy in β-Th. Further work is needed to confirm these findings.
General imaging properties of two-dimensional multimode interference couplers

Based on the guided-mode propagation analysis method and the self-imaging effect, the general imaging properties of the two-dimensional multimode interference coupler (2-D MMI) are generalized and discussed. The general formulas for the positions, intensities, and phases of the self-images, and for image overlap in 2-D MMIs are derived. The numbers, positions, intensities, and phases of the self-images are directly related to the position of the input field and the positional number. The self-imaging properties of 2-D MMIs can be regarded as the interference superposition of two orthogonal one-dimensional self-imaging effects. These results are verified by guided-mode propagation analysis.
Observation of the size-dependent blueshifted electroluminescence from nanocrystalline Si fabricated by KrF excimer laser annealing of hydrogenated amorphous silicon/amorphous-SiNx:H superlattices

Nanocrystalline silicon (nc-Si) was fabricated by KrF excimer laser annealing of hydrogenated amorphous silicon/amorphous-SiNx:H superlattices. A stable and reproducible electroluminescence (EL) based on these structures was observed at room temperature. It was found that the EL peak was significantly blueshifted from 780 to 600 nm with decreasing the a-Si:H sublayer thickness from 4.0 to 1.0 nm, while the intensity was also notably enhanced. The results suggest that the quantum confinement effect may play an essential role in visible light emissions from our present samples.
Systematic Trends in Hybrid-DFT Computations of BaTiO3/SrTiO3, PbTiO3/SrTiO3 and PbZrO3/SrZrO3 (001) Hetero Structures

We performed predictive hybrid-DFT computations for PbTiO3, BaTiO3, SrTiO3, PbZrO3 and SrZrO3 (001) surfaces, as well as their BaTiO3/SrTiO3, PbTiO3/SrTiO3 and PbZrO3/SrZrO3 (001) heterostructures. According to our hybrid-DFT computations for BO2 and AO-terminated ABO3 solid (001) surfaces, in most cases, the upper layer ions relax inwards, whereas the second layer ions shift upwards. Our hybrid-DFT computed surface rumpling s for the BO2-terminated ABO3 perovskite (001) surfaces almost always is positive and is in a fair agreement with the available LEED and RHEED experiments. Computed B-O atom chemical bond population values in the ABO3 perovskite bulk are enhanced on its BO2-terminated (001) surfaces. Computed surface energies for BO2 and AO-terminated ABO3 perovskite (001) surfaces are comparable; thus, both (001) surface terminations may co-exist. Our computed ABO3 perovskite bulk Γ-Γ band gaps are in fair agreement with available experimental data. BO2 and AO-terminated (001) surface Γ-Γ band gaps are always reduced with regard to the respective bulk band gaps. For our computed BTO/STO and PTO/STO (001) interfaces, the average augmented upper-layer atom relaxation magnitudes increased by the number of augmented BTO or PTO (001) layers and always were stronger for TiO2-terminated than for BaO or PbO-terminated upper layers. Our B3PW concluded that BTO/STO, as well as SZO/PZO (001) interface Γ-Γ band gaps, very strongly depends on the upper augmented layer BO2 or AO-termination but considerably less so on the number of augmented (001) layers.
Iterative Estimation of a Set of Linear Regression Equations

Abstract This article develops a method of calculating iterative estimates of the coefficients of a set of linear regression equations. There are p equations such that the explanatory variables are non-stochastic and it is assumed that the random disturbances of at least one pair of equations are correlated. Provided that either different explanatory variables enter the various equations or that if the same explanatory variables enter then the observations are different, it is possible to obtain estimators that are asymptotically more efficient than the simple one-at-a-time least squares estimators. The estimators developed herein are calculated recursively using the Gauss-Seidel method of iteration. It is shown that all of the iterations are asymptotically normal, and that in the limit the iterations have the same asymptotic distribution as the generalized least squares estimator proposed by Zellner. The iterative estimators directly exploit the correlations among the random disturbances. In addition p l.
