Human Leukocyte Antigen (HLA) Class I Susceptible Alleles Against COVID-19 Increase Both Infection and Severity Rate

Introduction Each country's difference in the severity rate of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be explained by the difference in human leukocyte antigen (HLA) class I molecules, which affects the reactivity of cytotoxic T lymphocyte (CTL). Methods To clarify the relationship between HLA class I and the severity rate, the binding repertoires of each HLA class I allele to SARS-CoV-2 peptides and the allele frequencies of HLA-A, -B, and -A/B haplotypes in each country were quoted. Results HLA-A1 and the number of deaths per million population (severity rate) in each country had an exponential approximation correlation with correlation coefficient R=0.4879. In addition, the correlation between the infected cases per million (infection rate) and the severity rate was linearly approximated, with R=0.7422. Weak HLA-A alleles with a repertoire of under 300 also had an exponential approximation correlation with the severity rate (R=0.5972), whereas there was a linear approximation with the infection rate (R=0.6808). Weak HLA-B alleles of 30 repertoires or less had no correlation with the severity rate (R=-0.1530). The weak HLA-A/B haplotype has a stronger effect on the severity rate than the weak HLA-A alone. Therefore, the simple HLA class I susceptibility index was calculated, and a strong correlation (R=0.7388) of an exponential approximation with the severity rate was obtained. Conclusions HLA class I susceptible alleles against COVID-19 increase both infection and severity rate. The weak HLA-A is a major factor of severity rate, whereas the weak -B alone has no correlation. However, the weak HLA-A/B haplotype has a stronger effect on the severity rate than the weak -A alone.
An Exploratory Analysis of the Portrayal of Mental Illness in Qatar’s Newspapers

Background Concerns have been raised about the role of the media influencing the public’s understanding of mental illness. Aim This study explored the extent and nature of mental health coverage in Qatar’s newspapers. A secondary aim was to compare the mental health-related coverage with that of diabetes. Methods This was a retrospective quantitative and qualitative analysis of textual data published in Qatari newspapers. Quantitative descriptive analysis was employed to determine the extent of media coverage while qualitative content analysis was employed to examine the discourse tone and assess the stigmatization of the main messages on the text. Results A total of 659 mental health-related articles were published; the main focus of the articles was on autism, depression, and non-pharmacological therapies for mental illness. Analysis of the retrieved articles revealed a predominantly informative content, with mostly non-stigmatizing tone except for non-national news that often linked mental illness with dangerousness or violence. A higher number of articles with mental health-related content than about diabetes were found. Conclusion Although the newspaper content analysis revealed mostly a non-stigmatizing tone in mental health reporting in newspapers, there is a need to increase representation of people with mental illness in print media, increase awareness of the diversity of treatments available, and increase more scientific reporting to raise mental health literacy in Qatar.
Could tumor spread through air spaces benefit from adjuvant chemotherapy in stage I lung adenocarcinoma? A multi-institutional study

Background: The benefit of adjuvant chemotherapy (ACT) remains unknown for patients with stage I lung adenocarcinoma (ADC) with spread through air spaces (STAS). This study investigated the effect of adjuvant chemotherapy in stage I ADC/STAS-positive patients. Methods: A total of 3346 patients with stage I ADC from five institutions in China were identified from 2009 to 2013, of whom 1082 were diagnosed with STAS (32.3%). By using the Kaplan–Meier method and Cox proportional hazard regression model, we explored the impact of STAS on prognosis, and determined if the use of adjuvant chemotherapy was associated with improved outcomes in patients with stage I ADC/STAS-positive. A validation cohort was also included in this study. Results: Patients with stage I ADC/STAS-positive in the primary cohort had unfavorable overall survival (OS) and disease-free survival (DFS). A multivariate Cox regression model confirmed the survival disadvantages of STAS in patients with stage I ADC [OS: hazards ratio (HR) = 1.877, 95% confidence interval (CI): 1.579–2.231; p < 0.001; DFS: HR = 1.895, 95% CI: 1.614–2.225; p < 0.001]. Lobectomy was associated with better OS and DFS than sublobar resection (SR) in both stage IA and IB ADC/STAS-positive. Similar results were observed in the validation cohort. For patients with stage IB ADC/STAS-positive, ACT was revealed as an independent factor for favorable survival (OS: HR = 0.604, 95% CI: 0.397–0.919; p = 0.018; DFS: HR = 0.565, 95% CI: 0.372–0.858; p = 0.007). However, among patients with stage IA ADC/STAS-positive, ACT was associated with improved outcomes only for those undergoing SR (OS: HR = 0.787, 95% CI: 0.359–0.949; p = 0.034; DFS: HR = 0.703, 95% CI: 0.330–0.904; p = 0.029). Conclusion: The presence of STAS was correlated with poor prognosis in patients with stage I ADC. Our study suggested that ACT might be considered for patients with stage IB ADC/STAS-positive and those with stage IA ADC/STAS-positive who underwent SR.
Meniscus-Mediated Organization of Colloidal Nanoparticles

We put forward a new strategy to elucidate and guide the processes underlying the organization of colloidal nanoparticles. The high wettability of toluene on a Teflon ring causes a nanoparticle solution on a silicon substrate to adopt a meniscus, rather than a droplet, shape. This simple ring configuration enables a systematic investigation of the interplay of contact-line dynamics and evaporation in pattern formation in nanoparticle assemblies.
The patterns of long-term repeat-buying in Dirichlet markets

Dirichlet markets are stationary and unsegmented, and characterised by predictable patterns of split-loyal buying. This is because, across the population, individual but different household purchase propensities tend to remain stable. Although Dirichlet theory is among the most robust in marketing science, it has not yet been shown from empirical evidence how or if these purchase propensities evolve in the long run, knowledge crucial to marketers concerned with disrupting category structure. This thesis now describes the patterns of long-term repeat-buying. The research approach adopted was the differentiated replication and extension of empirical generalisations under the new condition of extended time, evaluating observations in a 26-quarter household panel of continuous reporters against steady-state Dirichlet benchmarks. In successive and non-adjacent quarters, contrary to widely held beliefs, few cases of persistent brand share growth or decline were observed and quarterly category structures retained Dirichlet characteristics even over six years. But analysis of cumulative data aggregations revealed that underlying purchase propensities were not entirely stable, leading to a gradual deterioration in model fit to longer reference periods. The main pattern observed was an unpredicted and substantial increase in brand switching, but since this remained governed by Double Jeopardy, and category purchase incidence was largely steady, no segmentation resulted and cumulative shares remained near-stationary. Findings contribute to knowledge of the nature of long-run behavioural loyalty. They establish that new uses of the Dirichlet in modelling management periods at wider intervals are possible since the effects of trending propensities are marginal when viewed in medium term data. They reveal the evolution of the DJ relationship over the long-run, and they confirm the behavioural drivers of exceptional brand dynamics. Findings also account for several well-reported systematic deviations in short term Dirichlet fit, but perhaps most importantly, the discovery of long-run equilibrium coupled with the unpredicted but systematic underlying churn of buyers between brands offers no support for loyalty strategies. Rather, it emphasises the importance for practitioners of maintaining market share transaction by transaction.
Drivers and History of Late Fluid Flow: Impact on Midcontinent Reservoir Rocks

Abstract Late diagenesis records a common history of fluid flow in sub-Permian strata in the midcontinent, where fluid inclusion Th are higher than burial temperatures and Tmice show evolving salinity. Most negative δ18Odolomite and highest Th are at the top of the Mississippian. Fluid inclusion and geochemical data point to advective fluid flow out of basins utilizing Cambrian–Ordovician–Mississippian strata as an aquifer for hydrothermal fluids. The Pennsylvanian was a leaky confining unit. This system evolved from: Stage 1 Pennsylvanian–early Permian pulsed hydrothermal migration of connate brine and gas; between Stages 1 and 2, low-temperature Permian brine reflux; Stage 2 mixing between high-temperature and low-temperature brines during the Permian; and Stage 3 large-scale migration of hydrothermal brines and oil later during the Permian or after. Stages 1–3 were the most important late processes affecting Mississippian reservoirs, and record an inverted thermal structure with most impact of hot fluids at the top of the Mississippian. Stage 4 shows radiogenic 87Sr/86Sr in calcite, supporting a transition to localized fault pumping from basement, likely driven by Laramide fault reactivation. Stage 5 is the current system, with Ozark and Front Range uplift-driven fluid flow and potential for small-scale sporadic fault pumping.
Temperature, density, and pressure dependence of relaxation times in supercooled liquids

We have examined experimental and simulation data on the relaxation times (τα) and the viscosities in liquids and supercooled liquids as functions of temperature (T), density (ρ), and pressure (p). We achieve a data collapse by placing the data on master curves that depend only on a single density- and species-dependent (but T independent) effective interaction energy, E∞(ρ).

Membranes based on polyimide–polyaniline nanocomposites for pervaporation of organic mixtures

Polyimide-polyaniline nanocomposites were obtained by mixing poly{(4,4 0 -bis(4 00 -N-phenoxy)diphenylsul- fone)imide-1,3-bis(3,4-dicarboxyphenoxy)benzene} (PI) and polyaniline (PANI) solutions in N-methylpyrrolidone. These solutions were used for the preparation of homo- geneous and composite membranes. Uniform distribution of PANI particles in the membranes, resulted from inter- actions between macromolecules, was confirmed by transmission electron microscopy. Membranes based on PI and PI-PANI were tested in pervaporation of binary organic mixtures: methanol/toluene and methanol/cyclo- hexane and showed a remarkable selectivity with respect to methanol. In both pervaporation processes, selectivity was improved in PANI-containing membranes. Interac- tions between membrane polymers and liquid penetrants (methanol, toluene, and cyclohexane) were studied by measurements of surface tension, sorption, and pervapo- ration parameters.

EFFECT OF DIFFERENT LEVELS OF LIGNITIC COAL DERIVED HUMIC ACID ON GROWTH OF MAIZE PLANTS

In view of the high cost of chemical fertilizers, use of natural fertilizer sources for increasing crop production on a sustainable basis has become imperative. A pot experiment was conducted in silty clay loam, mixed, hyperthermic typic calciustepts, and Tarnab soil series to study the effect of different levels of humic acid (HA) derived from lignitic coal on the growth of maize (Zea maysL. Kissan). HA was sprayed on soil at the rate of 0, 50, 100, 150, 200, 250, and 300 mg kg−1 soil along with uniform dose of nitrogen–phosphorus–potassium (NPK) (120–90–60 kg ha−1). The addition of 50 and 100 mg kg−1 HA caused significant increase of 20 and 23% in shoot and 39 and 32% in root dry weight of maize plants as compared to control. The increasing levels of HA above 50 and 100 mg kg−1 produced no significant effect on maize yield. Soil organic matter content was improved slightly (7 to 14%) and pH values were decreased by 0.2 to 0.3 unit by the HA treatments. Addition of HA increased soil N concentration and plant N accumulation significantly over control with no significant differences within the treatments of different levels of HA applied. Soil P concentration improved significantly by the addition of 200 mg kg−1 HA whereas plant P accumulation was not significantly affected by the application of different levels of HA. Micronutrients [zinc (Zn), iron (Fe), manganese (Mn), and copper (Cu)] concentrations of soil and their accumulations by maize plants increased nonsignificantly over control by the application of HA. Laboratory incubation experiment conducted to study the effect of HA on soil biological and physicochemical properties showed that the addition of 0.5 and 1.0 kg ha−1 HA promoted CO2 evolution, increased bacterial population by 355% to 476%, fungi 610 to 716%, and cation exchange capacity of the soil by 13.8 to 28.9%. Results suggest that increases in growth of maize due to HA addition may be associated with the improved biochemical environment of the soil.
First Principles Calculations of Thermodynamic Quantities and Phase Diagrams of High Temperature BCC Ta-W and Mo-Ta Alloys

The thermodynamic properties of high temperature metals and alloys are studied using the statistical moment method, going beyond the quasi-harmonic approximations. Including the power moments of the atomic displacements up to the fourth order, the Helmholtz free energies and the related thermodynamic quantities are derived explicitly in closed analytic forms. The configurational entropy term is taken into account by using the tetrahedron cluster approximation of the cluster variation method (CVM). The energetics of the binary (Ta-W and Mo-Ta) alloys are treated within the framework of the first-principles TB-LMTO (tight-binding linear muffin tin orbital) method coupled to CPA (coherent potential approximation) and GPM (generalized perturbation method). The equilibrium phase diagrams are calculated for the refractory Ta-W and Mo-Ta bcc alloys.
Experimental study of the Ioffe-Regel criterion for amorphous indium oxide films

The Ioffe-Regel criterion predicts the existence of a metal-insulator transition in a film series when the parameter satisfies the criterion ; here is the Fermi wavenumber and is the elastic mean free path of the carriers. According to this criterion, films having are metallic, while films having are insulating. We experimentally observe the metal-insulator transition in amorphous indium oxide films at . The values of were calculated from room temperature resistivity and Hall voltage measurements, while the metal-insulator transition was determined from low-temperature resistivity data using the `w'-criterion of Mobius and of Zabrodskii and Zinov'eva.
Influence of Tire Formulation on the Products of Continuous Pyrolysis in a Conical Spouted Bed Reactor

The pyrolysis of waste tires in continuous mode has been studied in a pilot plant provided with a conical spouted bed reactor, in the 425−600 °C range, by feeding two types of tire materials with different contents of natural and synthetic rubber. The properties of the pyrolysis products have been characterized using different techniques for both the volatile and solid fraction. The liquid has been analyzed by means of GC/MS, GC×GC and simulated distillation, and the residual carbon black by elemental analysis and surface characterization. Neither temperature nor tire composition has a significant effect on the yields of gas, liquid and residual carbon black fractions, but they considerably affect product properties. The contents of natural rubber and styrene−butadiene rubber in the tire have a significant effect on the liquid composition (contents of aromatics and interesting raw materials, such as styrene and limonene). The carbon black obtained at 600 °C has a high surface area and is suitable for acti.
Physicochemical, Rheological, and Thermal Properties of Six Types of Honey from Various Floral Origins in Tunisia

The present study was undertaken to determine the physicochemical, rheological, and thermal properties of six types of Tunisian honey samples from various floral origins (eucalyptus, orange, thyme, mint, rosemary, and horehound). All the honey samples exhibited non-Newtonian behavior at a shear rate ranging between 0.01 and 500 s–1, with the highest levels of viscosity (µ) being observed for thyme, followed by eucalyptus, rosemary, mint, orange, and horehound honeys, respectively. The effect of temperature on the dynamic viscosity of the samples followed an Arrhenius-like pattern, with activation energy values ranging from 21.23 to 34.91 kJ/mol. The results from oscillatory rheology analysis also revealed that the loss modulus predominated over the storage one in the whole frequency range. As determined by differential scanning calorimetry, the glass transition (Tg) and melting temperatures of the Tunisian honey samples varied between –41.55 and –47.06 °C and between 197.9 and 221.1°C depending on their sugar compositions, respectively.
Multiple constraint analysis of regional land-surface carbon flux

We applied and compared bottom-up (process model-based) and top-down (atmospheric inversion-based) scaling approaches to evaluate the spatial and temporal patterns of net ecosystem production (NEP) over a 2.5 × 105 km2 area (the state of Oregon) in the western United States. Both approaches indicated a carbon sink over this heterogeneous region in 2003 (a relatively warm, dry year in western Oregon) and 2007 (near normal), with carbon uptake primarily in forested and agricultural areas. The statewide mean NEP for 2007 using the bottom-up approach was 80 gC m-2 yr-1, which compares with 145 gC m-2 yr-1 for the top-down approach. Seasonality of daily NEP at the ecoregion scale showed similar patterns across the two approaches, but with less sensitivity to seasonal drought in the top-down model. In 2003, simulated annual NEP was lower than in 2007 for both scaling approaches, but the reduction was stronger with the bottom-up approach. Estimates of mean NEP on forested lands from a forest inventory approach, and from the CarbonTracker inversion scheme, bracketed that of our bottom-up approach (ratios to bottom-up estimates were 1.3 and 0.3, respectively). These results support the need for a multiple constraint approach to evaluation of regional trace gas budgets.
Algebraic Models for Turbulent Transports in Premixed Flames

The thermal expansion induced by the chemical reactions taking place in a turbulent reactive flow of premixed reactants affects the velocity field so strongly that turbulent transports can be controlled by reaction rather than by turbulence. Moreover, thermal expansion is well-known to cause countergradient turbulent diffusion as well as flame-generated turbulence phenomena. In the present article, a splitting procedure of the velocity field is used that allows the identification of two different effects of the thermal expansion in the specific flamelets regime of turbulent premixed combustion: (i) the thermal expansion occurring through the local flames (direct effect) and (ii) the effect of thermal expansion on the velocity field associated to the growth of the flame surface (indirect effect). Algebraic closures for the turbulent transport terms of mass and momentum are proposed where the effect of the turbulent mixing (nonreactive effect) is modeled by classical closures, i.e., gradient law, while the contributions associated with thermal expansion are closed by taking advantage of flamelet relationships. Finally, this simple model is applied to the numerical simulation of a turbulent flame stabilized by the sudden expansion of a 2D channel. Corresponding results are satisfactorily compared with experimental data and confirm the ability of the model to represent the behavior of turbulent transports in premixed flames.
Soil dissolved organic matter sorption as influenced by organic and sesquioxide coatings and sorbed sulfate

The sorption of dissolved organic carbon (DOC) and its fractions as influenced by organic C (OC), sesquioxides amorphous Al(OH) 3 , ferrihydrite, goethite], and extractable SO 4 2 was investigated by modifying the properties of the Bs horizon of an Entic Haplorthod. Coating the Bs material with OC extracted from the Oa horizon of a mor forest floor layer decreased the sorption of total DOC. The effects on the sorption of the hydrophobic DOC fraction were little, whereas the sorption of the hydrophilic fraction was strongly reduced. At the highest OC coating levels, a net release of hydrophilic DOC occurred, indicating a displacement of indigenous hydrophilic substances from the soil by the sorbing hydrophobic dissolved organic matter (DOM). Coating of the soil material with sesquioxides clearly increased the sorption of DOC and its fractions. The strongest effects occurred when amorphous Al(OH) 3 was added, followed by ferrihydrite and goethite. Increased contents of extractable SO 4 2- did not affect the sorption of DOC on soil material. With increasing addition of DOC. however, the concentrations of SO 4 2- in the equilibrium solution increased. Adsorbing DOM seems to displace SO 4 2 bound to soil materials. Thus, DOM shows a higher affinity to sorb on soil material than SO 4 2 .

Modern version of volumetric apparatus for measuring gas-solid equilibrium data

This paper describes a modern version of the volumetric apparatus which was used for measuring gas-solid equilibrium data. It presents adsorption data for methane, ethane, ethylene, and propane at 38 and 149/sup 0/C on Kureha beads (GP Grade), an attrition-resistant activated carbon. The new apparatus was validated with literature data for the ethane-ethylene system on a molecular sieve (13X), and excellent agreement was obtained. The vacancy solution model was used for correlating pure-component isotherms, and excellent agreement was obtained.
