Aim: To assess the predictive role of hematological indices in the first trimester of pregnancy for gestational diabetes mellitus (GDM) and to compare the progressive changes in these indices between patients with and without GDM in their first and second trimesters.
Materials and Methods: Pregnant women screened for GDM in 24-28 gestational weeks and who had CBC test in the first and second trimesters were retrospectively investigated. Platelet mass index (PMI), neutrophil-to-lymphocyte ratios (NLR) and platelet-to-lymphocyte ratios (PLR) were calculated. The first trimester hematological indices were compared between normal glycemic patients and the patients with subsequent GDM. The progressive changes of these indices were compared.
Results: Three-hundred-sixty-eight women were enrolled and 17.9% had GDM. There was no difference between first trimester hematological indices, except PLR which was lower in GDM group, however, PLR was not an independent predictor. In normal-glycemic pregnant women hemoglobin, hematocrit, lymphocytes, platelets, mean-platelet-volume (MPV), plateletcrit (PCT), platelet-large-cell-ratio (PLCR) and PMI decreased significantly from first trimester to second trimester. White-blood-cells(WBC), neutrophils, nucleated-red-blood-cells(NRBC), immature granulocytes and NLR increased significantly, while no significant changes were detected in red-cell-distribution-width(RDW), platelet-distribution-width(PDW) and PLR. In GDM patients, hemoglobin, hematocrit, lymphocytes, platelets and PMI significantly decreased while WBC, neutrophils, MPV, immature granulocytes and NLR increased from first trimester to second trimester. RDW, PDW, PCT, PLCR, NRBC and PLR did not change.
Conclusion: None of the first trimester hematological indices have a predictive ability for subsequent GDM. The progressive changes in MPV can be used as an indicator to assess the development of GDM.
On the Impact of Random Residual Calibration Error on the Gibbs ILC CMB Estimates over Large Angular Scales
Authors: Sudevan Vipin , Saha Rajib 
Published: October 2020

Abstract
Residual errors in calibration coefficients corresponding to observed cosmic microwave background (CMB) maps are an important issue when estimating a pure CMB signal. These errors in the input-foreground-contaminated CMB maps, if not properly taken into account in a component separation method, may lead to bias in the cleaned CMB map and estimated CMB angular power spectrum. But the inability to exactly determine the calibration coefficients corresponding to each observed CMB map from a multifrequency CMB experiment makes it very difficult to incorporate their exact and actual values during the component separation method. Hence, the effect of any random and residual calibration error in the cleaned CMB map and its angular power spectrum of a component separation problem can only be understood by performing detailed Monte Carlo simulations. In this paper, we investigate the impact of using input-observed CMB maps with random calibration errors on the posterior density of a cleaned CMB map and theoretical CMB angular power spectrum over large angular scales of the sky following the Gibbs Internal-Linear-Combination (ILC) method. By performing detailed Monte Carlo simulations of WMAP and Planck temperature anisotropy observations, including their estimate on calibration errors, we show that the best-fit map corresponding to the posterior maximum is minimally biased in the Gibbs ILC method by a CMB normalization bias and residual foreground bias. The residual calibration-induced error in the best-fit power spectrum causes an overall 6% increase of the net error when added in quadrature with the cosmic-variance-induced error.
Electron-impact Excitation of Fe i
Authors: Conroy Andrew T. , Ballance Connor P. , Ramsbottom Catherine A. , Keenan Francis P. 
Published: October 2020

Abstract
The Fe i spectra emitted by astrophysical sources contain information on plasma parameters such as chemical abundances and magnetic fields. However, to determine these parameters requires detailed plasma modeling, which in turn needs accurate atomic data for processes such as radiative decay and electron-impact excitation in Fe i. A lack of fine-structure resolved collision strengths for transitions in Fe i is addressed in this paper with the presentation of data obtained from a Dirac R-matrix calculation. The suitability of our choice of target description is shown, with our energies generally within 7% of literature values. Various A-values are compared with other theoretical and experimental results, and the quality of the collision strengths produced in this work demonstrated. A comparison of 300- and 1000-level close-coupling expansions is made, the latter shown to eliminate pseudoresonances in the collision strengths at electron energies between 0.5 and 1.0 Ry. Maxwell-averaged effective collision strengths are presented, and the convergence of our data is shown in the temperature range 1000–100,000 K.
On the Rotation of the Solar Chromosphere
Authors: Xu Jing-Chen , Gao Peng-Xin , Shi Xiang-Jun 
Published: October 2020

Abstract
Rotation is a significant characteristic of the Sun and other stars, and it plays an important role in understanding their dynamo actions and magnetic activities. In this study, the rotation of the solar chromospheric activity is investigated from a global point of view with an over 40 yr Mg ii index. We determined the time-varying rotational period lengths (RPLs) with the synchrosqueezed wavelet transform, which provides high temporal and frequency resolution; furthermore, we compared the RPLs with the photospheric and coronal RPLs obtained from the sunspot numbers and the 10.7 cm radio flux data. The significance of the RPLs is taken into consideration. We found that the RPLs of the chromosphere exhibit a downward trend, as do those of the photosphere and corona; in addition, their RPLs at the recent four solar maxima also show a declining trend. This suggests that the rotation of the solar atmosphere has been accelerating during the recent four solar cycles, which is inferred to be caused by the declining strength of solar activity. The variations of the solar atmospheric RPLs show periodicities of multiple harmonics of the solar cycle period, and it is modulated by the solar activity cycle.
Standing on the Shoulders of Giants: New Mass and Distance Estimates for Betelgeuse through Combined Evolutionary, Asteroseismic, and Hydrodynamic Simulations with MESA

Published: October 2020

Abstract
We conduct a rigorous examination of the nearby red supergiant Betelgeuse by drawing on the synthesis of new observational data and three different modeling techniques. Our observational results include the release of new, processed photometric measurements collected with the space-based Solar Mass Ejection Imager instrument prior to Betelgeuse’s recent, unprecedented dimming event. We detect the first radial overtone in the photometric data and report a period of 185 ± 13.5 days. Our theoretical predictions include self-consistent results from multi-timescale evolutionary, oscillatory, and hydrodynamic simulations conducted with the Modules for Experiments in Stellar Astrophysics software suite. Significant outcomes of our modeling efforts include a precise prediction for the star’s radius:

. In concert with additional constraints, this allows us to derive a new, independent distance estimate of

pc and a parallax of

mas, in good agreement with Hipparcos but less so with recent radio measurements. Seismic results from both perturbed hydrostatic and evolving hydrodynamic simulations constrain the period and driving mechanisms of Betelgeuse’s dominant periodicities in new ways. Our analyses converge to the conclusion that Betelgeuse’s ≈400 day period is the result of pulsation in the fundamental mode, driven by the κ-mechanism. Grid-based hydrodynamic modeling reveals that the behavior of the oscillating envelope is mass-dependent, and likewise suggests that the nonlinear pulsation excitation time could serve as a mass constraint. Our results place α Orionis definitively in the early core helium-burning phase of the red supergiant branch. We report a present-day mass of 16.5–19 M
⊙—slightly lower than typical literature values.

En 2015, dans un contexte de crise pour le bipartisme PP-PSOE en Espagne, les résultats des élections « autonomiques » ont éclaté encore un peu plus les Cortès d’Aragon traditionnellement multipartites. Aux partis d’obédience nationale (PP, PSOE, et IU) se sont greffées les nouvelles propositions de Podemos et Ciudadanos tandis que les partis autonomistes, Partido Aragonés (PAR) et Chunta Aragonesista (CHA), ont maintenu leur présence parlementaire aux Cortès aragonaises. Au Palais de la Aljafería, siège du parlement aragonais, une majorité de gauche progressiste s’est dessinée (35 députés de PSOE, Podemos, CHA et IU) contre 32 pour le bloc conservateur (PP, PAR et Ciudadanos). Ce résultat a donné lieu à une coalition inédite pour le pouvoir exécutif aragonais (PSOE-CHA) ponctuellement soutenue au niveau législatif par Podemos et Izquierda Unida. Il sera question de voir comment les nationalistes de CHA, pourtant très affaiblis, ont réussi à imposer avec un seul ministère régional (“consejería”) des thématiques cruciales de l’agenda politique nationaliste : droits historiques, articulation du territoire, politique linguistique…

Isabel Gille – migrante espagnole en France – a produit son autobiographie en fin de vie, pendant qu’elle apprenait à écrire le français. Elle rend ainsi compte des apprentissages sociaux et personnels multiples qui accompagnent son expérience migratoire. Son récit inédit n’avait jamais été publié et a été très peu diffusé en dehors du contexte familial. Les enjeux de mise en lumière de l’histoire d’une personne inconnue du grand public, à l’écriture dite ordinaire paraissent cependant importants.

Authors: Nasiri Ardalan , Ang Simon S. 
Published: October 2020

Abstract
A double-layer ceramic electronic packaging technology that survives the Venusian surface temperature of 465°C was developed using a ceramic interlayer dielectric with gold conductors. A 60-μm ceramic interlayer dielectric served as the insulator between the top and bottom gold conductors on high-purity ceramic substrates. Test devices with AuPtPd metallization were attached to the top gold pads using a thick-film gold paste. Thermal aging for 115 h at 500°C and thermal cycling from room temperature to 450°C were performed. Dielectric leakage tests of the interlayer ceramic layer between the top and bottom gold conductors revealed a leakage current density of less than 50 × 10−7 A/cm2 at 600 V after thermal cycling. Gold conductor resistance increased slightly after thermal cycling. The die shear test showed a 33% decrease in die shear strength after thermal tests and its 6.16 kg-F die shear strength satisfies the Military Standard Product Testing Services (MIL-STD) method.

Published: October 2020

Abstract
High-power semiconductor applications require a thermal interface die attach material with high thermal conductivity to efficiently release the heat generated from these devices. Current thermal interface material solutions such as thermal grease, thermal pads, and silicones have been industry standards, however may fall short in performance for high-temperature or high-power applications. This article focuses on development of a cutting-edge die attach solution for thermal interface management, focusing on fusion-type epoxy-based Ag adhesive with an extremely low storage modulus and the thermal conductivity reaching up to 30 W/mK, and also very low-modulus, low-temperature pressureless sintering silver die attach with a thermal conductivity of 70 W/mK.

Se compendia, a continuación, los resultados obtenidos del uso de varios tratamientos de abono aplicados a siembras experimentales de tomate, variedad Plamar, en un suelo del tipo Coto arcilloso en la Subestación Experimental de Isabela. 1. La aplicación de 100 libras de nitrógeno por acre produjo significativamente mayores rendimientos de tomates comerciales por acre, que cuando no se aplicó nitrógeno o se aplicó este elemento a razón de 200 libras por acre. 2. El uso de abonos fosfatados aumentó la producción de tomates, obteniéndose los mayores rendimientos cuando se aplicaron 200 libras de P2O5 por acre. 3. La cosecha no respondió a las aplicaciones de potasa. 4. La aplicación de cachaza a razón de 20 toneladas por acre, motivó aumentos significativos en los rendimientos, al compararse con los tratamientos en los cuales no se usó abono alguno. 5. Cuando se combinaron 20 toneladas de cachaza con 100 libras de nitrógeno por acre o con 200 libras de P2O5 y K2O por acre, los rendimientos fueron superiores comparados con los tratamientos que recibieron cachaza o abonos químicos solamente. 6.

Se llevó a cabo un experimento con caña de azúcar de la variedad P.R. 980 en un suelo del tipo turba Tiburones en el Caño Tiburones, Arecibo. Se cosecharon una plantilla y dos retoños con los resultados siguientes: 1. La aplicación de abonos nitrogenados no aumentó el tonelaje de la caña, ni el porcentaje de sacarosa en la caña, ni el número de toneladas de caña por cuerda. 2. La caña respondió en un alto grado significativo a las aplicaciones de abonos fosfatados a razón de 150 libras de P2O5 por cuerda, en cuanto al tonelaje de caña. El uso de 300 libras de P2O5 por cuerda no indujo aumentos significativos sobre el tonelaje de caña que produjo la aplicación de 150 libras de P2O5 por cuerda. 3. El tonelaje de la caña aumentó significativamente mediante la aplicación de 300 libras de K2O por cuerda, pero no así con la aplicación de 150 libras de K2O por cuerda. 4. El efecto de los abonos sobre el porcentaje de sacarosa en la caña varió en forma tal que hubo un descenso en este porcentaje debido a la presencia de nitrógeno en la plantilla y un aumento significativo debido a la presencia de potasa en la plantilla y en el segundo retoño. 5. El tonelaje de azúcar aumentó significativamente mediante la aplicación de 150 libras de P2O5 y 300 libras de K2O por cuerda. 6. Los valores de fósforo en la hoja se correlacionaron significativamente con los rendimientos relativos de azúcar disponible a 96° por cuerda. Un valor de fósforo en la hoja de 0.17 por ciento o mayor se asoció al hecho de que la caña no respondiera a la aplicación de los abonos fosfatados. 7. Los valores de potasio en la hoja no estuvieron correlacionados significativamente con los rendimientos relativos, como en el caso de los valores de fósforo en la hoja. Valores de potasio de 1.0 por ciento estuvo asociado con los rendimientos relativos de azúcar al 75 por ciento, por lo que la caña respondió a las aplicaciones de potasa.

Fertilizer trials were made with tomatoes, Rutgers variety, and cucumbers, P.R. 39 and Ashley varieties, in the Southwestern section of Puerto Rico with the following results: 1. For tomatoes at Jayuya, on a Jayuya silty clay loam, highest yields were obtained with 50 pounds of nitrogen and 100 pounds each of P2O5 and K2O per acre. Liming at 1,000 pounds per acre did not increase yields significantly. 2. The more fertile Santa Isabel clay of the Lajas Valley failed to respond significantly to variations in nitrogen, phosphate, or potash for tomatoes or cucumbers. 3. Cucumbers grown on a Paso Seco silty clay loam at the Fortuna Substation showed significant yield responses to 100 pounds of nitrogen and 50 pounds of P2O5 per acre.
Hydrolytic Proteins of Sugarcane: The Q Enzyme
Authors: Alexander Alex G. 
Published: October 2020

A polysaccharide branching factor, apparently identical with the Q enzyme of potatoes, has been extracted from sugarcane leaves and partly characterized. Procedures used successfully by other workers to isolate the Q enzyme from potato extracts failed to yield the branching system free from other catalysts of sugarcane. A preparation satisfactory for characterization studies was obtained by precipitating protein from water extracts with lead acetate, eluting the precipitate with bicarbonate solution, and fractionating the bicarbonate extract with ammonium sulfate. The Q enzyme was precipitated between 0 and 35-percent saturation, at pH 7.2 and 22°C. The 0 to 35-percent fraction was virtually free of acid phosphatase and ß-amylase. Traces of starch phosphorylase (P enzyme) were present but caused no difficulty in the absence of phosphate buffers. However, an amylase of the a type was present, which interferred seriously with Q enzyme measurements in acid media, particularly in the area of pH 4 to 5. Q enzyme was moderately active between pH 6.5 and 9.0, with optimum pH at approximately 7.5. The α-amylase was very weak at pH values higher than 6.5. Soluble potato starch was employed as substrate throughout these studies. Optimum concentration was 2.0 to 2.5 mg./ml. of digest, α-amylase was most active against 0.5 mg./ml. of digest. Q enzyme experienced an 85-percent inhibition by lead ions, 0.5 mg./ml., when acting upon a substrate level of 0.25 mg./ml. of digest. Increasing the starch concentration to 2.5 mg./ml. partly removed the lead effects, indicating that the inhibition was competitive. Fluoride, 0.025 mg./ml., completely eliminated α-amylase activity at pH 7.5, but had little effect at pH 4.0. α-amylase was also suppressed by copper. Dialysis against distilled water had little effect upon Q enzyme, but strongly retarded amylase after 6 and 10 hours. Twenty-two-hour dialysis caused no further changes in either enzyme. The most favorable temperature tested with Q enzyme was 30°C, although the system was fairly active at temperatures as low as 7°C. α-amylase was not active at 7°C, but achieved the maximum rate measured at 26°C. A series of sugarcane tissues was tested for Q enzyme, including meristem, leaves +1 and +2, leaves +6 and +7, sheaths +1 and +2, 8 to 10 nodes, and 8 to 10 internodes. Activity was far greater in leaves +6 and +7 than any other tissue tested, α-amylase was most active in the meristem preparations. Electrophoresis studies showed that the 0 to 35-percent fraction was composed of at least three distinct protein constituents. These were presumed to represent Q enzyme, α-amylase, and starch phosphorylase. The significance of Q enzyme in sugarcane is briefly discussed. A diagram is presented to illustrate the role of the polysaccharide branching factor in relation to the starch -and sucrose-forming pathways.
