Benefit of assimilating satellite all‐sky infrared radiances on the cloud and precipitation prediction of a long‐lasting mesoscale convective system over the Tibetan plateau
Authors: He Jie , Ma Xulin , Chen Xingchao 
Published: July 2023

AbstractHeavy rainfall events in the warm season (May–September) over the Tibetan Plateau (TP) region and its downstream areas are often closely related to eastward‐propagating Tibetan Plateau Vortices (TPVs). Hence, improving the prediction of TPVs and their associated convective activity is of paramount importance, given the significant potential impacts they can have on densely populated downstream regions, including but not limited to flooding and damages. In this study, a typical long‐lived TPV that occurred in July 2008 was used for the first time to explore the benefit of assimilating satellite all‐sky infrared radiances on the cloud and precipitation prediction of the TPV‐induced eastward‐propagating mesoscale convective system (MCS). The all‐sky infrared radiances from the water vapor (WV) channel of the geostationary Meteosat‐7 and other conventional observations were assimilated into a 4‐km grid spacing regional model using the ensemble Kalman filter. The results revealed that the all‐sky infrared data assimilation improved the cloud, precipitation, dynamical, and thermodynamical analyses as well as 0–12‐hr deterministic and ensemble forecasts. Compared with the experiment in which the all‐sky infrared radiances were not assimilated (non‐radiance experiment), the experiment with assimilated all‐sky infrared radiances yielded clearly improved initial wind and cloud fields, 1–12‐hr cloud forecasts, and 1–6‐hr precipitation forecasts. This study indicates that assimilation of all‐sky satellite radiances has the potential for improving the operational cloud and precipitation forecasts over the TP and its downstream areas.
Automated fluvial hydromorphology mapping from airborne remote sensing
Authors: Hedger Richard D. , Gosselin Marie‐Pierre 
Published: July 2023

AbstractMapping fluvial hydromorphology is an important part of defining river habitat. Mapping via field sampling or hydraulic modeling is however time consuming, and mapping hydromorphology directly from remote sensing data may offer an efficient solution. Here, we present a system for automated classification of fluvial hydromorphology based on a deep learning classification scheme applied to aerial orthophotos. Using selected rivers in Norway, we show how surface flow patterns (smooth or rippled surfaces vs. standing waves) can be classified in imagery using a trained convolutional neural network (achieving a training and validation accuracy of >95%). We show how integration of these classified surface flow patterns with information on channel gradient, obtained from airborne topographic LiDAR data, can be used to compartmentalize the rivers into hydromorphological units (HMUs) that represent the dominant flow features. Automated classifications were broadly consistent with manual classifications that had been made in previous ground surveys, with equivalency in automated and manually derived HMU classes ranging from 61.5% to 87.7%, depending on the river stretch considered. They were found to be discharge‐dependent, showing the temporally dynamic aspect of hydromorphology. The proposed system is quick, flexible, generalizable, and provides consistent classifications free from interpretation bias. The deep learning approach used here can be customized to provide more detailed information on flow features, such as delineating between standing waves and advective diffusion of air bubbles/foam, to provide a more refined classification of surface flow patterns, and the classification approach can be further advanced by inclusion of additional remote sensing methods that provide further information on hydromorphological features.

Published: July 2023

AbstractThe cost‐effective hydrogen production via electrolyser depends on the availability of highly efficient, low‐cost, and robust OER and HER catalysts. We fabricated Ni−NC and NC electrocatalysts via a simple, cheap, and scalable by direct mixing route followed by carbonization at 900 °C under the N2 atmosphere. The addition of Ni into NC substantially increases the crystallite size, particle size, and ID/IG ratio. The Ni−NC sample exhibits excellent bifunctional OER and HER activities. The overpotentials to achieve (−) 10 mA.cm−2 current density for the OER were 400 mV and 263 mV for the HER in 0.1 M NaOH electrolyte. The Tafel slope analysis of the Ni−NC sample for the OER (123 mV.dec−1) revealed the hydroxyl‐ion discharge is the rate‐determining step. In comparison, for the HER (145 mV.dec−1), the Volmer‐Heyrovsky pathway is the rate‐determining step. The short‐term stability test displayed the sustained current density for 10 h at 1.68 V vs. RHE.

Sequential One‐Pot Process to Construct a Dual C−C Bond: Synthesis of Fluorenes and Total Synthesis of 4‐O‐Demethyl‐nobilone
Authors: Shekhar Chander , Satyanarayana Gedu 
Published: July 2023

AbstractHerein, a sequential one‐pot process is described for accessing 9,9‐disubstituted‐9H‐fluorenes via the formation of a dual C−C bond, and this protocol is successfully extended to the total synthesis of the naturally occurring 4‐O‐demethyl‐nobilone. The overall process proceeds via Suzuki coupling between ortho‐bromobenzylic(tertiary) alcohols and arylboronic acids, followed by zinc(II) iodide‐mediated intramolecular cyclization reactions. The strategy has been applied to an inclusive range of substitutions over ortho‐bromobenzylic(tertiary) alcohols and arylboronic acids.

Published: July 2023

AbstractHerein, a general applicable method for the atom‐economic catalytic construction of a broad range of 1,2‐dialkylaminoethers is presented. By taking advantage of an elaborated protocol for the photocatalyzed anti‐Markovnikov selective hydroamination of nonactivated alkenes, a series of 1,2‐dialkylaminoethers was accessed by reacting readily available vinyl ethers with secondary alkyl amines. It was demonstrated that the reaction can be performed at low catalyst loadings while the commonly employed triisopropylbenzene thiol Hydrogen Atom Transfer (HAT)‐catalyst was replaced by an easier accessible mesityl thiol. Furthermore, the inexpensive and readily available diphenyl disulfide was proven as suitable HAT‐catalyst alternative for the efficient hydroamination of simple vinyl ethers.

Published: July 2023

AbstractMetal‐free trifluoromethyltellurolation of indoles with [Me4N][TeCF3] in the presence of NIS allowed a convenient synthesis of 3‐TeCF3‐substituted indole derivatives in good yields. The reaction proceeded smoothly under mild conditions and showed good functional group tolerance. It was noteworthy that [Me4N][TeCF3] had a distinct reaction profile for indole systems in comparison with [Me4N][SeCF3]. The trifluoromethyltellurolated products were unprecedented and decomposed rapidly even in the darkness and under a N2 atmosphere. This work represents the first metal‐free trifluoromethyltellurolation of indoles with the sensitive [Me4N][TeCF3] salt as TeCF3 reagent.

Published: July 2023

AbstractThe synthesis of large‐scale 2D conductive metal‐organic framework films with tunable thickness is highly desirable but challenging. In this study, an Interface Confinement Self‐Assembly Pulling (ICSP) method for in situ synthesis of 4‐in. Ni‐BHT film on the substrate surface is developed. By modulating the thickness of the confined space, the thickness of Ni‐BHT films could be easily varied from 4 to 42 nm. To eliminate interference factors and evaluate the effect of film thickness on the catalytic performance of HER, an electrocatalytic microdevice based on the Ni‐BHT film is designed. The effective catalytic thickness of the Ni‐BHT film is found to be around 32 nm. Finally, to prepare the electrocatalytic microdevice array, over 100 000 microdevices on a 4‐in. Ni‐BHT film are integrated. The results show that the microdevice array has good stability and a high hydrogen production rate and could be used to produce large amounts of hydrogen. The wafer‐scale 2D conductive metal‐organic framework's fabrication greatly advances the practical application of microdevices for massive hydrogen production.

AbstractPotassium‐ion batteries (PIBs) have broad application prospects in the field of electric energy storage systems because of its abundant K reserves, and similar “rocking chair” operating principle as lithium‐ion batteries (LIBs). Aiming to the large volume expansion and sluggish dynamic behavior of anode materials for storing large sized K‐ion, bismuth telluride (Bi2Te3) nanoplates hierarchically encapsulated by reduced graphene oxide (rGO), and nitrogen‐doped carbon (NC) are constructed as anodes for PIBs. The resultant Bi2Te3@rGO@NC architecture features robust chemical bond of Bi─O─C, tightly physicochemical confinement effect, typical conductor property, and enhanced K‐ion adsorption ability, thereby producing superior electrochemical kinetics and outstanding morphological and structural stability. It is visually elucidated via high‐angle annular dark‐field scanning transmission electron microscopy (HAADF‐STEM) that conversion‐alloying dual‐mechanism plays a significant role in K‐ion storage, allowing 12 K‐ion transport per formular unit employing Bi as redox site. Thus, the high first reversible specific capacity of 322.70 mAh g−1 at 50 mA g−1, great rate capability and cyclic stability can be achieved for Bi2Te3@rGO@NC. This work lays the foundation for an in‐depth understanding of conversion‐alloying mechanism in potassium‐ion storage.
High consumption of pesticides in agricultural fields leads to prevalence of cancer cases in rural pockets of eastern India: A case study
Authors: Bhoi Rosismita , Mahananda Malaya Ranjan , Pradhan Abanti 
Published: July 2023

AbstractThis study was performed to evaluate the carcinogenic health risk of pesticides used in agricultural field in rural pockets of eastern India. The analysis of pesticide residue in rice grain sample was performed by Gas Chromatography Mass Spectrometry (GC‐MS). It was observed that for pesticide DDT, the HR values was ranging between 0.5 to 3.2 and for lindane HR was 0.4 to 1.1, respectively. The DDT and Lindane exhibited HR values >1 in some sampling sites which revealed the carcinogenic effects and HR <1 in some sampling sites which revealed non carcinogenic effects of same pesticide. These results revealed a clear indication of potential carcinogenic health risk to human health through consumption of contaminated rice in some areas of Bargarh district. DDT has a long half‐life, so it persists in the environment for a longer period of time and induces carcinogenic risk to human health predominantly than other pesticide lindane. A case study on cancer prevalence in Bargarh district was also carried out to support the findings of quantitative analysis. The primary data collected from the cancer affected area by personal questionnaires method to the person concern and the secondary data collected from the Bargarh District Head Quarters Hospital's register. The cancer death reported by the from the year 2015 to 2021 was 320, 380, 293, 323, 278, 409, 346 in the year of 2015, 2016, 2017, 2018, 2019, 2020, 2021 respectively, with the total number of 2349 cases. From the questionnaire data, it was observed that the occurrence of male and female cancer cases was 51.75% and 48.25%, respectively. Therefore, it was concluded that there was no significant difference in gender wise cancer prevalence. The most affected age group was 51–60, that is, 26.92% followed by 41–50, that is, 23.42%. Therefore, it was concluded that the middle‐aged adults (40–60) were more vulnerable to the cancer than young adults (3–40) and old adults (60–100). The most prevalent cancer was breast (22.72%) followed by stomach (14.33%).

Published: July 2023

ABSTRACTObjectivePre‐eclampsia (PE) is a pregnancy complication associated with premature cardiovascular disease morbidity and mortality (i.e. before 60 years of age or in the first year postpartum). PE is associated with adverse left ventricular (LV) remodeling in the peri‐ and postpartum periods, an independent risk factor for cardiovascular disease. This study aimed to compare LV geometry by LV mass (LVM) and LVM index (LVMI) between participants with a high vs low screening risk for preterm PE in the first trimester.MethodsThis was a prospective cohort study of singleton pregnancies between 11 + 0 and 13 + 6 weeks' gestation that underwent screening for preterm PE as part of their routine first‐trimester ultrasound assessment at a tertiary center in London, UK, from February 2019 until March 2020. Screening for preterm PE was performed using the Fetal Medicine Foundation algorithm. Participants with a screening risk of ≥ 1 in 50 for preterm PE were classified as high risk and those with a screening risk of ≤ 1 in 500 were classified as low risk. All participants underwent two‐dimensional and M‐mode transthoracic echocardiography.ResultsA total of 128 participants in the first trimester of pregnancy were included in the analysis, with 57 (44.5%) participants screened as low risk and 71 (55.5%) participants as high risk for PE. The risk groups did not vary in maternal age and gestational age at assessment. Maternal body surface area and body mass index were significantly higher in the high‐risk group (all P < 0.05). The high‐risk participants were significantly more likely to be Afro‐Caribbean, nulliparous and have a family history of hypertensive disease in pregnancy as well as other cardiovascular disease (all P < 0.05). In addition, mean arterial blood pressure (P < 0.001), mean heart rate (P < 0.001), median LVM (130.06 (interquartile range, 113.62–150.50) g vs 97.44 (81.68–114.16) g; P < 0.001) and mean LVMI (72.87 ± 12.2 g/m2 vs 57.54 ± 12.72 g/m2; P < 0.001) were significantly higher in the high‐risk group. Consequently, those in the high‐risk group were more likely to have abnormal LV geometry (37.1% vs 7.0%; P < 0.001).ConclusionsEarly echocardiographic assessment in participants at high risk of preterm PE may unmask clinically healthy individuals who are at increased risk for future cardiovascular disease. Adverse cardiac remodeling in the first trimester of pregnancy may be an indicator of decreased cardiovascular reserve and subsequent dysfunctional cardiovascular adaptation in pregnancy. © 2023 The Authors.

Published: July 2023

AbstractPurposePatients undergoing total knee arthroplasty (TKA) are at high risk for thromboembolic events compared to non‐surgical patients. Both anticoagulants and antiplatelet agents are used as antithrombotic prophylaxis in TKA. The aim of this review is to understand the role of aspirin in the prevention of thromboembolic events and to compare its efficacy and safety with the main anticoagulants used in antithromboembolic prophylaxis in TKA.MethodsA systematic review and meta‐analysis was performed according to the PRISMA guidelines. An electronic systematic search was conducted using PubMed, Scopus, and the Cochrane Central Registry to evaluate studies that compared aspirin with other anticoagulants, in terms of deep venous thrombosis and pulmonary embolism after TKA. The meta‐analysis compared the rate of complications between aspirin and other anticoagulants.ResultsThirteen studies were included in the systematic review for a total of 163,983 patients, and 10 studies were included in the meta‐analysis. The meta‐analysis demonstrated no statistically significant differences between aspirin and other anticoagulants in terms of the rate of deep venous thrombosis (OR 0.93, 95% CI 0.81–1.08, p = 0.35) and pulmonary embolism (OR 0.89, 95% CI 0.56–1.41, p = 0.61).ConclusionAspirin is safe, effective, and not inferior to other main anticoagulants in preventing thromboembolic events following TKA.
Proof of Vogan’s conjecture on Arthur packets: irreducible parameters of p-adic general linear groups
Authors: Cunningham Clifton , Ray Mishty 
Published: July 2023

AbstractIn this paper we prove Vogan’s conjecture on local Arthur packets, as recalled in Cunningham et al. [Arthur packets for p-adic groups by way of microlocal vanishing cycles of perverse sheaves, with examples, Memoirs of the American Mathematical Society, Boston, 2022, Section 8.3, Conjecture 1(a)], for irreducible Arthur parameters of p-adic general linear groups. This result shows that these Arthur packets may be characterized by properties of simple perverse sheaves on a moduli space of Langlands parameters.
The behavioral economics of dynamically inconsistent behavior: a critical assessment
Authors: Krügel Sebastian , Uhl Matthias 
Published: July 2023

AbstractPreferences often change—even in short time intervals—due to either the mere passage of time (present-biased preferences) or changes in visceral or environmental conditions (state-dependent preferences). On the basis of empirical findings concerning state-dependent preferences, we critically discuss the “Aristotelian” view of unitary decision makers in economics. We illustrate that the conceptualization of preferences as “present-biased” as opposed to “state-dependent” has very different normative implications for which preferences should be considered “rational.” Empirically, however, the two concepts are very difficult to distinguish. The economist can justify any paternalistic intervention if she can conceptualize changing preferences so flexibly, and she can easily become a benevolent despot. We therefore urge for a more careful “Heraclitean” view of decision-making that accepts that a person may consist of multiple selves.
Auerbach, Lotka, and Zipf: pioneers of power-law city-size distributions
Authors: Rybski Diego , Ciccone Antonio 
Published: July 2023

AbstractPower-law city-size distributions are a statistical regularity researched in many countries and urban systems. In this history of science treatise we reconsider Felix Auerbach’s paper published in 1913. We reviewed his analysis and found (i) that a constant absolute concentration, as introduced by him, is equivalent to a power-law distribution with exponent $$\approx 1$$

, (ii) that Auerbach describes this equivalence, and (iii) that Auerbach also pioneered the empirical analysis of city-size distributions across countries, regions, and time periods. We further investigate his legacy as reflected in citations and find that important follow-up work, e.g. by Lotka (Elements of physical biology. Williams & Wilkins Company, Baltimore, 1925) and Zipf (Human behavior and the principle of least effort: an introduction to human ecology, Martino Publishing, Manfield Centre, CT (2012), 1949), does give proper reference to his discovery—but others do not. For example, only approximately 20% of city-related works citing Zipf (1949) also cite Auerbach (Petermanns Geogr Mitteilungen 59(74):74–76, 1913). To our best knowledge, Lotka (1925) was the first to describe the power-law rank-size rule as it is analyzed today. Saibante (Metron Rivista Internazionale di Statistica 7(2):53–99, 1928), building on Auerbach and Lotka, investigated the power-law rank-size rule across countries, regions, and time periods. Zipf’s achievement was to embed these findings in his monumental 1949 book. We suggest that the use of “Auerbach–Lotka–Zipf law” (or “ALZ-law”) is more appropriate than “Zipf’s law for cities”, which also avoids confusion with Zipf’s law for word frequency. We end the treatise with biographical notes on Auerbach.
