Published: December 2023

AbstractTopoclimate, orographically enhanced rain on windward slopes and leeward rain shadows, control rainfall variability in tropical mountains. Such variability may cause a substantial societal impact in populated highlands such as in Ethiopia. This study aims at understanding the rainfall diurnal cycle and the orographic driving factors over the Ethiopian highlands using the ALARO‐0 regional climate model at convection‐permitting resolution, over a period of 21 years. While the evaluation against satellite‐based observations shows a too early onset of the model diurnal cycle and a too low nocturnal rainfall, several conclusions can be drawn from the model simulations presented here. Elevation is the most important determining factor for modelled rainfall with increased average rainfall and rainfall per rainfall event towards higher elevations. Ethiopia's simulated summer rain exhibits a pronounced diurnal cycle with the highest rainfall occurring during the early afternoon hours and the minimum values occurring in the late night. Average rainfall and rainfall per rainfall event are substantially larger on the windward sides than on the leeward sides of the mountains, except during the peak hours. The diurnal cycles of temperature and humidity start earlier in the morning and recede later than the cycles of wind speed and rainfall. Moreover, rainfall peaks occur earlier in the day at higher elevations, and at night in valleys and in Afar Triangle. Rain intensities around noon on the leeward side are slightly higher than those on the windward side of the highest mountains (>3000 m). This could be due to delayed onset of cloudiness and larger morning insolation on the leeward side of the mountain, but this needs further study. The prevalence of windward over leeward rainfall, the stark contrast in wind‐speed diurnal cycle between windward and leeward slopes, and the early peak hour of surface air and dew point temperature all point towards temperature‐induced rather than wind‐induced convection. These differences are likely to determine hydrology and vegetation distribution, and farmers economy at large. Hence, the need for a way out from the ‘one‐size‐fits‐all’ agro‐ecosystem management approach towards a site‐specific policy that takes into account climatic differences.

Published: December 2023

AbstractAnimals face strong environmental variability even on short time scales particularly in shallow coastal habitats, forcing them to permanently adjust their metabolism. Respiration rates of aquatic ectotherms are directly influenced by water temperature, whereas ingestion rates might additionally be influenced by behavior. We aim to understand how respiration and ingestion rates of an aquatic invertebrate respond to changing temperature during a diurnal thermal fluctuation cycle and how both processes are related. We studied the benthopelagic mysid Neomysis integer as an important food web component of coastal ecosystems. Mysids were collected at the southern Baltic Sea coast and exposed in the laboratory to either constant temperature of 15°C or daily temperature fluctuation of 15 ± 5°C. Short‐term (1–2 h) respiration and ingestion rates were measured at four equidistant time points within 24 h and did not differ among time points at constant temperature, but differed among time points in the fluctuating treatment. Respiration was highest at the thermal maximum and lowest at the thermal minimum. Ingestion rates showed the opposite pattern under fluctuation, likely due to differences in underlying thermal performance curves. When temperature transited the average, the direction of temperature change influenced the animals' response in respiration and ingestion rates differently. Our results suggest that respiration is not only instantaneously affected by temperature, but also influenced by the previously experienced direction of thermal change. Our experiment, using an important non‐model organism, delivered new insights on the relationship between the crucial organismal processes ingestion and respiration under thermal variability.

Published: December 2023

AbstractBackgroundHeating around deep brain stimulation (DBS) in magnetic resonance imaging (MRI) occurs when the time‐varying electromagnetic (EM) fields induce currents in the electrodes which can generate heat and potentially cause tissue damage. Predicting the heating around the electrode contacts is important to ensure the safety of patients with DBS implants undergoing an MRI scan. We previously proposed a workflow to predict heating around DBS contacts and introduced a parameter, equivalent transimpedance, that is independent of electrode trajectories, termination, and radiofrequency (RF) excitations. The workflow performance was validated in a unilateral DBS system.PurposeTo predict RF heating around the contacts of bilateral (DBS) electrodes during an MRI scan in an anthropomorphic head phantom.MethodsBilateral electrodes were fixed in a skull phantom filled with hydroxyethyl cellulose (HEC) gel. The electrode shafts were suspended extracranially, in a head and torso phantom filled with the same gel material. The current induced on the electrode shaft was experimentally measured using an MR‐based technique 3 cm above the tip. A transimpedance value determined in a previous offline calibration was used to scale the shaft current and calculate the contact voltage. The voltage was assigned as a boundary condition on the electrical contacts of the electrode in a quasi‐static (EM) simulation. The resulting specific absorption rate (SAR) distribution became the input for a transient thermal simulation and was used to predict the heating around the contacts. RF heating experiments were performed for eight different lead trajectories using circularly polarized (CP) excitation and two linear excitations for one trajectory. The measured temperatures for all experiments were compared with the simulated temperatures and the root‐mean‐squared errors (RMSE) were calculated.ResultsThe RF heating around the contacts of both bilateral electrodes was predicted with ≤ 0.29°C of RMSE for 20 heating scenarios.ConclusionThe workflow successfully predicted the heating for different bilateral DBS trajectories and excitation patterns in an anthropomorphic head phantom.

AbstractObjectivesThe aim of this study was to evaluate the psychometric properties of the newly developed Diagnostic Interview for Sexual Dysfunctions in Women (DISEX‐F), which covers diagnostic criteria of DSM‐5 and ICD‐11.MethodsThirty‐two actresses portrayed 32 cases of female sexual dysfunctions (= standardized patients). To calculate inter‐rater reliability, each standardized patient was interviewed independently by two trained diagnosticians using the DISEX‐F. Interviews were videotaped, and each videotape was evaluated by two other independent diagnosticians. Sensitivity and specificity were calculated by comparing the assigned diagnoses to the target diagnoses pre‐determined in the case vignettes. As a side criterion, the acceptance of the DISEX‐F among diagnosticians was assessed.ResultsSpecificity was found to be generally clinically satisfying (DSM‐5: 0.90–0.99; ICD‐11: 0.95–0.99), while sensitivity (DSM‐5: 0.40–0.92; ICD‐11: 0.71–0.96) and inter‐rater reliability (DSM‐5: Cohen's kappa = 0.44–1; ICD‐11: Cohen's kappa = 0.75–0.94) greatly varied between classification systems and disorders. Imprecise acting and false differential diagnostic decisions were identified as major sources of mismatch. The acceptance of the DISEX‐F was high.ConclusionResults encourage usage of the DISEX‐F for ICD‐11 diagnoses. Mixed results were found for DSM‐5 diagnoses, which can partly be explained by shortcomings in DSM‐5 criteria.

Published: December 2023

AbstractAdaptability is an important psychological trait for college students. However, the components of adaptability contained significant inconsistencies in previous studies. On the one hand, there were discrepancies among the adaptability dimensions. On the other hand, significant inconsistencies were found in the connections among different aspects of adaptability. Therefore, the current research aimed to investigate the latent relationship among various components of adaptability. To achieve this, 565 volunteers were recruited to complete a 5‐min cross‐sectional survey. Subsequently, 402 participants were recruited to complete an 8‐min longitudinal survey. The current study comprised two sub‐studies: Study 1 utilized a structural equation model to examine the relationship between various dimensions of adaptability in a cross‐sectional dataset, while Study 2 employed the cross‐lagged panel model to validate the latent relationship between emotional adaptability and other types of adaptability using a longitudinal dataset. Results from the cross‐sectional study indicated significant associations between emotional adaptability and other types of adaptability, with coefficients ranging from .231 to .588. The longitudinal study revealed that emotional adaptability at Time 2 and 3 could be predicted by learning adaptability, professional adaptability, and economic adaptability at Time 1 and 2. Consequently, the research concluded that individuals' emotional maladjustment could be predicted by maladaptive difficulties in learning, professional settings, homesickness, interpersonal relationships, and economics.
Helicobacter pylori FlgN binds its substrate FlgK and the flagellum ATPase FliI in a similar manner observed for the FliT chaperone

Published: December 2023

AbstractIn bacterial flagellum biogenesis, secretion of the hook–filament junction proteins FlgK and FlgL and completion of the flagellum requires the FlgN chaperone. Similarly, the related FliT chaperone is necessary for the secretion of the filament cap protein FliD and binds the flagellar export gate protein FlhA and the flagellum ATPase FliI. FlgN and FliT require FliJ for effective substrate secretion. In Helicobacter pylori, neither FlgN, FliT, nor FliJ have been annotated. We demonstrate that the genome location of HP1120 is identical to that of flgN in other flagellated bacteria and that HP1120 is the homolog of Campylobacter jejuni FlgN. A modeled HP1120 structure contains three α‐helices and resembles the FliT chaperone, sharing a similar substrate‐binding pocket. Using pulldowns and thermophoresis, we show that both HP1120 and a HP1120Δ126–144 deletion mutant bind to FlgK with nanomolar affinity, but not to the filament cap protein FliD, confirming that HP1120 is FlgN. Based on size‐exclusion chromatography and multi‐angle light scattering, H. pylori FlgN binds to FlgK with 1:1 stoichiometry. Overall structural similarities between FlgN and FliT suggest that substrate recognition on FlgN primarily involves an antiparallel coiled‐coil interface between the third helix of FlgN and the C‐terminal helix of the substrate. A FlgNΔ126–144 N100A, Y103A, S111I triple mutant targeting this interface significantly impairs the binding of FlgK. Finally, we demonstrate that FlgNΔ126–144, like FliT, binds with sub‐micromolar affinity to the flagellum ATPase FliI or its N‐terminal domain. Hence FlgN and FliT likely couple delivery of low‐abundance export substrates to the flagellum ATPase FliI.

Published: December 2023

AbstractAn effective way to enhance the photovoltaic properties of a small molecule is to modify the side groups into donor units. Herein three news small molecules A‐π‐D‐π‐A, denoted Dye1‐3, have been designed, from experimentally reported one noted (R), by insertion of various heteroatoms (S, O, Se) on the electron‐donating benzodithiophene (Donor (D = BDT)) part. From the calculated results, the dihedral angle between BDT and side‐chain affects the distribution of density on the ground state, gap energy, and intramolecular charge transfer of Dyes. In particular, the Dye3 compound, with the smaller dihedral angle, shows that the furan groups in the side chain of D, participates in the distribution of density on the ground state and consequently the charge transfer is improved. Additionally, Dye3 has the lower reorganization energy revealing that this material exhibits better charge mobility. Using the Scharber diagram, Dye3‐PCBM heterojunction shows a power conversion efficiency of around 7%. Overall, this work suggests that the photovoltaic properties can be affected by the modification of heteroatoms on side groups of donor parts in small molecules.
Theoretical insights into the effect of surface structure and anion ordering on the properties of SrTaO2N for photocatalytic water splitting
Authors: Qu He , Yang Shuyuan , Zhou Xin 
Published: December 2023

AbstractAs one of the representative perovskite‐type oxynitride photocatalysts, SrTaO2N has the ability to split water in the visible‐light region. It was found that the surface modification and interfacial design of SrTaO2N‐based materials are closely related to the photocatalytic activity, but the microscopic mechanisms of these experimental phenomena are not well understood. In this work, we have utilized density functional theory (DFT) calculations to investigate the effect of anion ordering and exposed terminations on the electronic structures, optical absorption, water adsorption and the mechanisms of water oxidation and reduction reactions of SrTaO2N. Our results indicate that cis configurations are more stable than trans configurations. The anion ordering has an important effect on the band gap and optical absorption coefficient. The terminations with exposed Ta atoms are more stable and have bigger work functions than those with exposed Sr atoms possibly due to the bonding ionicity and surface dipoles. The dissociative adsorption of water is energetically more favorable than the molecular adsorption on most surfaces. The highly active sites of hydrogen evolution reaction (HER) are the exposed nonmetal atoms. Terminations with exposed Sr and N atoms have lower overpotentials (0.70–0.77 V) of oxygen evolution reaction (OER) than others. They are comparable to the calculated results of common photocatalysts, such as Co3O4 and TiO2. This study sheds light on the relationship between the termination structure with different anion orders and the photocatalysis‐related properties of SrTaO2N at a molecular level, which provides guidance for constructing highly active photocatalytic materials.
Adaptive neural network control of non‐affine multi‐agent systems with actuator fault and input saturation

Published: December 2023

AbstractAn adaptive neural network fault‐tolerant control method is proposed for the non‐affine multi‐agent systems with actuator failure and input saturation. Through the transformation of the original multi‐agent systems, an equivalent model is proposed. Considering that the signal input of multi‐agent systems is limited, this article will solve the input saturation problem. But in a real system, the actuator would probably fail. Therefore, a fault tolerant control algorithm is proposed to solve the fault problem in the systems. In this article, an adaptive distributed controller is designed to eliminate the uncertainty of the systems. At the same time, the integral barrier Lyapunov function is selected to verify the stability. Finally, a simulation example is given to demonstrate the effectiveness of the proposed method.

Herein, a simple method is proposed for developing bimetallic Fe/M‐N4/nitrogen‐doped porous carbon (NPC) (M‐Zn or Mg) conductive metal–organic framework (c‐MOF) composites because of their great potential in replacing conventional catalysts. The prepared composite MOF exhibits remarkable catalytic activity for both hydrogen evolution reaction (HER) and oxygen reduction reaction (ORR), surpassing the performance of the state‐of‐the‐art transition metal‐N4 cathode catalysts. These composites demonstrate excellent selectivity for a four‐electron transfer, facilitated by an associative reaction pathway that functions as the rate‐determining step. Therefore, they offer high half‐wave and onset potential values for ORR, i.e., 0.92 and 1.02 V for Fe/Mg‐N4‐NPC (hexaminobenzene (HAB)‐3@NPC) at a current density of 4.11 mA cm−2, and 0.89 and 0.99 V for Fe/Zn‐N4‐NPC (HAB‐2@NPC) at a current density of 3.8 mA cm−2, respectively. In addition, they provide low overpotentials of 21 and 64 mV at the current density of 10 mA cm−2 with Tafel slopes of 47.9 and 34.2 mV dec−1 for HER, respectively. Furthermore, when utilized as the cathode in bifunctional electrode assembly cells, they provide low cell voltages of 1.412 V at a current density of 20mA cm−2. In the membrane electrode assembly, the HAB‐3@NPC composite demonstrates an optimal power density of 0.861 Wcm−2, thus underscoring its potential in practical applications.

Published: December 2023

AbstractAtmospheric water vapor is a crucial factor in the Earth's water cycle. As an important greenhouse gas, changes in the spatio‐temporal distribution of atmospheric water vapor can contribute to the occurrence of various extreme weather phenomena. Lidar, with its high spatial and temporal resolutions, has great potential for applications in water vapor profile detection. Raman lidar and differential absorption lidar (DIAL) have been successfully used to detect atmospheric water vapor. System calibration is crucial to ensure that the measured profile accurately represents the concentration profile of atmospheric water vapor. Choosing an effective system calibration method can ensure the accuracy of long‐term lidar measurements. This paper reviews the latest progress and applications of atmospheric water vapor lidar calibration in recent years. The basic principles of Raman lidar and DIAL calibration are introduced. Various methods and benefits of system calibration are discussed. Raman lidar has three commonly used calibration methods: external calibration, internal calibration, and hybrid calibration methods. The most commonly used method is external calibration based on radiosondes. DIAL is usually implemented with an advantageous self‐calibration method. Finally, potential development directions for atmospheric water vapor lidar and calibration technology are discussed.This article is categorized under:

AbstractBringing together discussions of voice and second-order choices, the chapter addresses the complexity of financial solutions for women’s disempowerment and how radio as a tool can represent the voices of impoverished and/or marginalised communities. Drawing on broadcasts by a radio studio in each of Niger and Burkina Faso and listener feedback, it discusses how listeners, women and men alike, perceive the financial needs of women. It examines how guests use radio to call out both to those in authority to make changes and to women to actively seek solutions. The chapter finds that whilst audiences are anxious to find ways to obtain money, guests raise a note of caution, warn against quick fixes and advise to look to the long term.
The Genocide of the Christians, Turkey 1894–1924
Authors: Morris Benny , Ze’evi Dror 
Published: December 2023

AbstractWe set out in 2010 to look afresh at the massacre of Turkey’s Armenians in 1915. While most of the world’s historians accepted the narrative that the Ottoman Turkish government had carried out a deliberate, pre-planned, systematic “genocide,” there were some—especially in Turkey—who disputed this. So, having no real knowledge or opinion either way, we decided to take a look at the vast, accessible documentation, in Turkey, the United States and Western Europe, and make up our own minds.What we discovered was that the story was much deeper and wider. The campaign of mass murder and ethnic cleansing was carried out, in staggered fashion, over a thirty-year period, between 1894 and 1924. It encompassed not only Turkey’s Armenians but also all the other Christian communities in the country, primarily the Greeks, but also the various Assyrian sects. The process of ethnic-religious cleansing was characterized by rounds of deliberate large-scale massacre, alongside systematic expulsions, forced conversions, and cultural annihilation that together amounted to genocide. At the beginning of this period, Christians had constituted about 20 percent of the population of Asia Minor; by 1924 the proportion of Christians in Turkey had fallen to 2 percent.The destruction of the Christian communities was the result of the deliberate policy of three successive Ottoman and Turkish governments –Abdülhamid II in 1894–1896, the CUP (the Young Turks) from 1914–1918, and the Nationalist regime under Ataturk during 1919–1924 –a policy that most of the country’s Muslim inhabitants did not oppose, and many enthusiastically supported. The murders, expulsions, and forced conversions were ordered by government officials and carried out by other officials, soldiers, gendarmes, policemen and, often, tribesmen and the civilian inhabitants of towns and villages. All of this occurred with the active participation of Muslim clerics and the encouragement of the Turkish-language press. This, we believe, is the inescapable conclusion to be drawn from the massive documentation we consulted, some of it seen and used for the first time.
