The League of Nations and the Protection of Minorities – Rediscovering a Great Experiment
Authors: Hilpold Peter 
Published: March 2022

After World War I the far-reaching border changes in Europe created a large number of new minorities. As a consequence, special protection measures had to be introduced. With the League of Nations’ minority protection system an extraordinary experiment was started. After World War II this system was largely ignored and fell into oblivion.
In the past all too easily the minorities themselves were held responsible for the failure of this system. In this context it is often said that minorities behaved in a disloyal manner and therefore it was at least understandable that minority states over the years treated their minorities badly and finally denounced their obligations. In reality, however, such an attitude rests on a radical misinterpretation of the loyalty principle and on a denial of historic facts. All in all, the ideas and concepts of these times live on and are shaping modern human rights thinking.
Playing Hide-and-Seek in the German Press

Published: March 2022

Abstract
This paper analyzes the topic of World War I vertical camouflage—that is, camouflaging objects on the ground from observation from the air—particularly showing its presence and absence in German public discourse of the time. Together with the dazzle scheme for ships, vertical camouflage represented a strategic visual novelty of World War i. The introduction of new visualities (e.g. the airplane view) and increased visibility (through optical technologies like aerial photography) drove the armies to elaborate specific camouflage patterns, employing both naturalistic and abstract motifs. Although widespread scholarship explores camouflage in the Great War, most of the narratives focus on the evolution of horizontal camouflage from the animal world, the mutual influences of military camouflage and avant-garde art, and the role of women in camouflage workshops. Nevertheless, contrary to the interest shown in large-scale deception projects in World War ii, only a restricted number of studies explore the practice of World War i vertical camouflage outside the context of Allied use.

Abstract
This paper addresses responses to Drawing Down the Moon by Shannon Grimes, James Davila, Gregory Shaw, and Naomi Janowitz, using the cues of extraordinary efficacy, performance, social location, and ends to determine whether something is labeled magic and by whom. In each of the papers, the cue of social location appears as the most significant, even though the others each play a role as well.
A Cascading Bias Correction Method for Global Climate Model Simulated Multiyear Precipitation Variability
Authors: Frei Allan , Mukundan Rajith , Chen Jie , Gelda Rakesh K. , Owens Emmet M. , Gass Jordan , Ravindranath Arun 
Published: March 2022

Abstract
The use of global climate model (GCM) precipitation simulations typically requires corrections for precipitation biases at subgrid spatial scales, typically at daily or monthly time scales. However, over many regions GCMs underestimate the magnitudes of multiyear precipitation extremes in the observed climate, resulting in a likely underestimation of the magnitudes of multiyear precipitation extremes in future scenarios. The objective of this study is to propose a method to extract from GCMs more realistic scenarios of multiyear precipitation extremes over time horizons of decades to one century. This proposed correction method is analogous to widely used bias correction methods, except that it is applied to variability at longer time scales than previous implementations (i.e., multiyear rather than daily or monthly). A case study of precipitation over a basin from the New York City water supply system demonstrates the potential magnitude of the underestimation of multiyear precipitation using uncorrected GCM scenarios, and the potential impact of the correction on multiyear hydrological extremes. Overall, it is a practical, conceptually simple approach meant for water supply system impact studies, but can be used for any impact studies that require more realistic multiyear extreme precipitation extreme scenarios.

Significance Statement
The purpose of this study is to present a practical method to address a particular difficulty that in some regions arises in climate change impact studies: global climate models tend to underestimate the multiyear variability of precipitation over some regions, resulting in an underestimation of the magnitudes and/or intensities of prolonged droughts as well as prolonged wet periods. The method is analogous to widely used bias correction methods, except it is applied to variability at longer time scales than previous implementations (i.e., multiyear rather than daily or monthly). It is designed to provide more realistic estimates of extreme hydrological scenarios during the twenty-first century. Our particular interest is for managers of water supply systems, but the method may be of interest to others for whom multiyear precipitation extremes are critical.

Abstract
Meanders formed where the Antarctic Circumpolar Current (ACC) interacts with topography have been identified as dynamical hot spots, characterized by enhanced eddy energy, momentum transfer, and cross-front exchange. However, few studies have used observations to diagnose the dynamics of ACC standing meanders. We use a synoptic hydrographic survey and satellite altimetry to explore the momentum and vorticity balance of a Subantarctic Front standing meander, downstream of the Southeast Indian Ridge. Along-stream anomalies of temperature in the upper ocean (150–600 m) show along-stream cooling entering the surface trough and along-stream warming entering the surface crest, while warming is observed from trough to crest in the deeper ocean (600–1500 m). Advection of relative vorticity is balanced by vortex stretching, as found in model studies of meandering currents. Meander curvature is sufficiently large that the flow is in gradient wind balance, resulting in ageostrophic horizontal divergence. This drives downwelling of cooler water along isopycnals entering the surface trough and upwelling of warmer water entering the surface crest, consistent with the observed evolution of temperature anomalies in the upper ocean. Progressive along-stream warming observed between 600 and 1500 m likely reflects cyclogenesis in the deep ocean. Vortex stretching couples the upper and lower water column, producing a low pressure at depth between surface trough and crest and cyclonic flow that carries cold water equatorward in the surface trough and warm water poleward in the surface crest (poleward heat flux). The results highlight gradient–wind balance and cyclogenesis as central to dynamics of standing meanders and their critical role in the ACC momentum and vorticity balance.
Significance Statement
The Antarctic Circumpolar Current (ACC) in the Southern Ocean is a nearly zonal current that encircles Antarctica. It acts as a barrier between warmer water equatorward and colder water poleward. In a few regions where the current encounters strong topographic changes, the current meanders and opens a pathway for heat to travel across the ACC toward Antarctica. We surveyed a meander in the ACC and examined the along-stream change of temperature. In the upper ocean, temperature changes are caused by a vertical circulation, bringing cool water down when entering the surface trough (the part of the meander closest to the equator), and warm water up when exiting the surface trough and entering the surface crest. At depth, cold water is transported equatorward in the surface trough and warm water poleward in the surface crest, leading to a net transport of heat poleward. This study highlights the importance of the secondary circulation within a meander for generating cross-ACC flows and moving heat toward Antarctica.

Abstract
The evaluation and usefulness of lightning prediction for the Indian subcontinent are demonstrated. Implementation of the lightning parameterizations based on storm parameters, in the Weather Research and Forecasting (WRF) Model, with different microphysics schemes are carried out. With the availability of observed lightning measurements over Maharashtra from the lightning detection network (LDN), lightning cases have been identified during the pre-monsoon season of 2016–18. Lightning parameterization based on cloud top height defined by a reflectivity threshold factor of 20 dBZ is chosen. Initial analysis is carried out for 16 lightning events with four microphysical schemes for the usefulness in lightning prediction. Objective analysis is carried out and quantitative model performance (skill scores) is assessed based on observed data. The skills are evaluated for 10- and 50-km2 boxes from the 1-km domain. There is good POD of 0.86, 0.82, 0.85, and 0.84, and false alarm ratio (FAR) of 0.28, 0.25, 0.29, and 0.26 from WSM6, Thompson, Morrison, and WDM6, respectively. There is an overestimation in lightning flash with a spatial and temporal shift. The fractional skill score is evaluated as a function of spatial scale with neighborhoods from 25 to 250 km. These high skill scores and high degree of correlation between observations and model simulation gives us confidence to use the system for real-time operational forecast over India. The skill for 2019 and 2020 pre-monsoon are calculated to address the predictability of operational lightning prediction over India.

Significance Statement
A high-resolution model, namely, the Weather Research and Forecasting (WRF) Model, with multiple microphysics parameterization schemes and lightning parameterization is used here. The objective analysis is carried out for the lightning cases over India and the quantitative performance is assessed. The results highlight that there is fairly good probability of detection (POD) of 0.86, 0.82, 0.85, and 0.84 and false alarm ratio (FAR) of 0.28, 0.25, 0.29, and 0.26 from four different microphysical schemes (WSM6, Thompson, Morrison, and WDM6, respectively). These high skill scores and high degree of correlation between observations and model simulation gives us confidence to use the system for real-time operational forecast. The validation of lightning forecast system deployed over India for five pre-monsoon months in real time is carried out, which gives POD of 0.90, FAR of 0.64, hit rate of 0.57, and POFD of 0.50 for the whole Indian region.
“I Was Learning Every Step of the Way”: Student Perceptions About a New Required Foundational Master of Public Health Program Planning Course
Authors: Stolow Jeni , Lederer Alyssa 
Published: March 2022

Objective: Tulane University School of Public Health and Tropical Medicine created a program planning course required for all master of public health (MPH) students to address the revised 2016 Council on Education for Public Health (CEPH) foundational competencies. The objective of this study was to examine students’ feedback on this new class based on their reflective writing. Methods: Students across 3 class sections during 3 semesters (fall 2018, spring 2019, and fall 2019) wrote a reflection paper as a final assignment about their course experience (N = 102). We conducted a conventional qualitative content analysis of deidentified student responses to systematically examine themes in the overarching areas of what students found valuable about the course and what they would want to be improved. We calculated frequency counts of themes to further contextualize the findings. Results: Students found the following aspects of the course valuable: a positive perception shift toward program planning (93.1%), new transferable career skills (87.3%), the course format (77.5%), course content (69.6%), working in teams (52.0%), course assignments (47.1%), and the instructional team (31.4%). Critiques included the following: more support for course assignments (39.2%), challenges of working in teams (27.5%), aspects of the course format (25.5%), gaps in course content (19.6%), and wanting more consultations with the instructional team (5.9%). About 14% of students stated there was nothing or little they would change about the course. Conclusion: Overall, the course received positive feedback from students. They identified several valuable course components and areas that could be enhanced, which we have worked to improve. We offer the course as a potential model for how schools and programs of public health can meet the 2016 CEPH competencies.
Hepatic enhancement at computed tomography: is there a dependence on body weight past institutional contrast dosing limits?
Authors: Kesen Savas , Svensson Anders , Thor Daniel , Brismar Torkel B. 
Published: March 2022

Background Although described in product monographs, the maximum contrast media (CM) dose at computed tomography (CT) varies among institutions. Purpose To investigate whether an upper limit of 40 g of iodine in women and 50 g in men is sufficient or if there is a body weight (BW) dependence of mean hepatic enhancement (MHE) beyond those thresholds. Material and Methods At our institution, CM injection duration is fixed to 30 s and dosed 600 mg iodine/kg up to 40 g in women and 50 g in men. Pre- and post-contrast hepatic attenuation values (HU) were retrospectively obtained in 200 women and 200 men with glomerular filtration rate >45 mL/min undergoing 18-flurodeoxyglucose PET-CT (18F-FDG PET-CT) of which half weighed below and half above those dose thresholds using iodixanol 320 mg iodine/mL or iomeprol 400 mg iodine/mL. The correlation between BW and MHE was assessed by simple linear regression. Results Weight range was 41–120 kg in women and 47–137 kg in men. There was no significant relationship between MHE and BW in women receiving <40 g (r = −0.05, P = 0.63) or in men receiving <50 g (r = 0.18, P = 0.07). Above those thresholds there was an inverse relationship (r = −0.64, P<0.001 in women and r = −0.30, P<0.002 in men). There was no apparent upper limit where the dependence of hepatic MHE on BW decreased. Hepatosteatosis limited MHE. Conclusion Adjusting CM to BW diminishes the dependence of MHE on BW. There was no apparent upper limit for the relationship between BW and MHE in heavier patients at CM-enhanced CT.

Objectives Most epidemiologic studies on soft tissue sarcomas (STS) and bone sarcomas (BS) are performed in western countries, with few in the Middle East and North Africa region. We describe the epidemiology of sarcomas in Lebanon using the medical records database at the American University of Beirut Medical Center (AUBMC). Methods This single-center retrospective cohort study included patients with sarcomas registered in the database between 2015 and 2019. Their charts were reviewed for baseline characteristics, tumor biology and location, treatment modalities, recurrence, metastasis, and death. Results The cohort included 234 patients with STS and 99 patients with BS. Most tumors were <10 cm in size. The most common subtypes were liposarcoma for STS and osteosarcoma for BS. The most common location of STS was the thigh. The most frequent sites of STS metastasis were the lungs. Histological subtype, smoking status, and tumor size and grade were significant for progression-free survival (PFS) in patients with STS. By multivariable analysis, smoking was significantly associated with poorer PFS in STS. For BS, only tumor grade was significant for PFS. Conclusion The epidemiology of sarcomas at AUBMC is similar to that previously reported. Smoking history was associated with poorer survival in patients with STS.
Study on the Quimby-tooth rotor profile for dry screw vacuum pumps
Authors: Li Dantong , He Zhilong , Wu Weifeng , Xing Ziwen 
Published: March 2022

This paper summarizes three Quimby-tooth rotor profile (QRP) generation models for dry screw vacuum pumps. Seven typical profiles are generated and compared to reveal their differences in curve structure, meshing line, parameter design range, and geometrical characteristics. The analysis indicates that there still is insufficient design flexibility for the typical profiles in the application of conical rotors. Therefore, a novel rotor profile is further proposed, in this paper, by modifying an existing profile. The advantage of the novel profile is identified through a specific design case. Results show that the summarized profile generation models provide an effective means to generate typical profiles and create novel profiles. In comparison with traditional profiles, the proposed profile achieves a 2.8% reduction of the contact line length and a 1% boost of the internal compression degree for conical rotors. This paper presents effective references for profile design and optimization of dry screw vacuum pumps. Graphic Abstract [Formula: see text]

Published: March 2022

Diabetic retinopathy (DR) is a common diabetic complication that severely impacts the life quality of diabetic patients. Recently, cellular senescence in human retinal endothelial cells (HRECs) induced by high glucose has been linked to the pathogenesis of DR. Fluorometholone (FML) is a glucocorticoid drug applied in the treatment of inflammatory and allergic disorders of the eye. The objective of the present study is to investigate the protective function of FML on high glucose-induced cellular senescence in HRECs. The in vitro injury model was established by stimulating HRECs with 30 mm glucose. After evaluating the cytotoxicity of FML in HRECs, 0.05% and 0.1% FML were used as the optimal concentration in the entire experiment. It was found that the excessive released inflammatory factors including tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-8 (IL-8) in HRECs induced by high glucose were significantly suppressed by FML, accompanied by the inhibitory effects on the expression levels of vascular endothelial growth factor (VEGF) and tissue factor (TF). Declined telomerase activity and enhanced senescence-associated β-galactosidase (SA-β-gal) activity were found in high glucose-challenged HRECs, which were dramatically alleviated by FML, accompanied by the inactivation of the p53/p21 and retinoblastoma (Rb) signaling. Interestingly, FML ameliorated high glucose-induced dephosphorylation of Akt. Lastly, the protective effects of FML against high glucose-induced cellular senescence in HRECs were abolished by the co-treatment of the PI3K/Akt signaling inhibitor LY294002, suggesting the involvement of this pathway. Taken together, these data revealed that FML-inhibited high glucose-induced cellular senescence mediated by Akt in HERCs, suggesting a novel molecular mechanism of FML.

Published: March 2022

Background Our purpose is to develop a model combining radiomic features of radiotherapy localisation computed tomography and clinical characteristics that can be used to estimate overall survival in patients with nasopharyngeal carcinoma treated with intensity-modulated radiotherapy following induction chemotherapy. Methods We recruited 145 patients with pathologically confirmed nasopharyngeal carcinoma between February 2012 and April 2015. In total, 851 radiomic features were extracted from radiotherapy localisation computed tomography images for the gross tumour volume of the nasopharynx and the gross tumour volume of neck metastatic lymph nodes. The least absolute shrinkage and selection operator algorithm was applied to select radiomics features, build the model and calculate the Rad-score. The patients were divided into high- and low-risk groups based on their Rad-scores. A nomogram for estimating overall survival based on both radiomic and clinical features was generated using multivariate Cox regression hazard models. Prediction reliability was evaluated using Harrell’s concordance index. Results In total, seven radiomic features and one clinical characteristic were extracted for survival analysis, and the combination of radiomic and clinical features was a better predictor of overall survival (concordance index = .849 [confidence interval: .782-.916]) than radiomic features (concordance index = .793 [confidence interval: .697-.890]) or clinical characteristics (concordance index = .661 [confidence interval: .673-.849]) alone. Conclusion Our results show that a nomogram combining radiomic features of radiotherapy localisation computed tomography and clinical characteristics can predict overall survival in patients with nasopharyngeal carcinoma treated with intensity-modulated radiotherapy following induction chemotherapy more effectively than radiomic features or clinical characteristics alone.
