COVID-19 Death Rates in Iran and Iraq: Possible Relations Between Iraq’s Pre-COVID-19 Mass Gatherings and Its Low Death Rate
Authors: Amani Amir , Namdar Ahmadabad Hasan , Nikravesh Abbas , Zarei Javad , Haghbin Ali 
Published: October 2022

AbstractIn recent years, COVD-19 has made millions of death worldwide. When reviewing the death rate, we encountered a very notable difference in death rate of Iran and Iraq, which are two neighboring countries. Investigating the COVID-19 risk factors, parameters, such as ethnicity and vaccination, do not appear not to be affecting our observation. We also could not find important differences in mortality rate being under-reported in the two countries. In this letter, we tried to discuss the possible effect of Iraq pre-COVID-19 mass gatherings on the death rate. The authors would like to highlight the effect of immune system on COVID-19.
Reconstructing historical 3D city models
Authors: Morlighem Camille , Labetski Anna , Ledoux Hugo 
Published: October 2022

AbstractHistorical maps are increasingly used for studying how cities have evolved over time, and their applications are multiple: understanding past outbreaks, urban morphology, economy, etc. However, these maps are usually scans of older paper maps, and they are therefore restricted to two dimensions. We investigate in this paper how historical maps can be ‘augmented’ with the third dimension so that buildings have heights, volumes, and roof shapes. The resulting 3D city models, also known as digital twins, have several benefits in practice since it is known that some spatial analyses are only possible in 3D: visibility studies, wind flow analyses, population estimation, etc. At this moment, reconstructing historical models is (mostly) a manual and very time-consuming operation, and it is plagued by inaccuracies in the 2D maps. In this paper, we present a new methodology to reconstruct 3D buildings from historical maps, we developed it with the aim of automating the process as much as possible, and we discuss the engineering decisions we made when implementing it. Our methodology uses extra datasets for height extraction, reuses the 3D models of buildings that still exist, and infers other buildings with procedural modelling. We have implemented and tested our methodology with real-world historical maps of European cities for different times between 1700 and 2000.

AbstractIn the US Southwest and Northwest Mexico, people and turkeys (Meleagris gallopavo) have had a reciprocal relationship for millennia; turkeys supplied feathers, meat, and other resources, whereas people provided food, shelter, and care. To investigate how turkeys fit within subsistence, economic production, sociopolitical organization, and religious and ritual practice in the Mimbres Valley of southwestern New Mexico, we report on genetic (mtDNA) and stable isotope (δ13C, δ15N) data from turkeys recovered from Mimbres Classic period (AD 1000–1130) sites. Results indicate that Mimbres aviculturists had haplogroup H1 and H2 turkeys, and most ate maize-based diets similar to humans, but some ate nonmaize and mixed diets. We contextualize these data to other turkey studies from the northern Southwest and discuss how the human-turkey relationship began, the evidence for pens and restricting turkey movement, and the socioecological factors related to turkey management during the Classic period, particularly the challenges associated with providing maize to turkeys during times of environmental stress. This study has broad relevance to places where people managed wild, tame, and domestic animals, and we offer new insights into how prehispanic, small-scale, middle-range agricultural societies managed turkeys for ritual and utilitarian purposes.
Making and taking theriac: an experimental and sensory approach to the history of medicine
Authors: Ahnfelt Nils-Otto , Fors Hjalmar , Wendin Karin 
Published: October 2022

AbstractThis paper explores historically used medicaments by making them, or rather reworking them, in a modern laboratory and assessing them for taste, flavour and odour using sensory analysis and a trained panel of sensory assessors. Our test subject is the famous panacea theriac andromachalis, which is subjected to the methods of experimental history of science to create experimental data. We emphasize the importance of the sensory experience, in both the making and the taking of theriac. From antiquity and well into the nineteenth century, medical practitioners and patients held that the sensory qualities of medicaments were of significance. But sensory information is notoriously difficult to transmit textually, and today we know very little about the sensory characteristics of theriac, and other medicines of the past. This is a problematic lacuna in our knowledge of how actors perceived and used them. By choosing the reworking and sensory framework, we can approach early modern pharmacy both as a craft and as a creative process. Thus our study emphasizes the artisanal, or craft, aspect of medicine making. It indicates how the art of medicine making was integrated with and connected to a medical practice which relied heavily on direct sensory assessments of medicaments, disease and patients. Our purpose is, however, not to try to find out how historical medicine makers and patients ‘really felt’ when they experienced the act of smelling and tasting medicines. Our aim is rather to discuss what the sensory experience of making and tasting adds to the investigation of textual sources. Thus, by attempting to access information about the experience of medicine through experimental means, we aim to enrich and complement historical understanding of the medicines and medical theories of the past.
International Clientelistic Networks: The Case of Venezuela at the United Nations General Assembly, 1999–2015
Authors: Carvalho Thales , Belém Lopes Dawisson 
Published: October 2022

ABSTRACTThis article introduces the concept of international clientelism and discusses how this diplomatic tool was employed by Venezuela under Hugo Chávez and Nicolás Maduro as a means to get political support from several Latin American and Caribbean countries. We operationalize the concept and apply it to assess Venezuelan practices put forth in the region. We argue that the reach of Caracas’s diplomatic strategy is broader and deeper than that of simple vote-buying tactics, as it implies the promotion of structural rather than contingent ties, shielding the country against unfavorable moves in international fora. An empirical test using data for all LAC countries for the years 1999–2015 confirms that clientelistic linkages produced political support for Venezuela at the United Nations General Assembly while also moving its partners away from the United States in that institution.
The vicarious liability of sports governing bodies and competition organisers
Authors: Brown James 
Published: October 2022

AbstractThis is the first work to explore the possibility of holding sports governing bodies and competition organisers vicariously liable for the tortious behaviour of athletes that compete under their auspices. In contrast to other scholarly contributions on vicarious liability in sport, this paper examines the scope of responsibility for athletes in individual sports (as opposed to team sports). It begins by drawing upon the recent tribunal proceedings between professional cyclist Jess Varnish and British Cycling to analyse the employment status of government-funded individual athletes. In calling for a contextual and policy-sensitive approach to the definition of an ‘employee’, this paper argues that certain normative and theoretical considerations ought to be granted more or less weight depending on the particular legal issue animating the dispute. Thereafter, and with one eye on the overly intrusive regulatory provisions found in sports such as tennis and golf, this paper also demonstrates that the vicarious liability of governing bodies and competition organisers could equally be extended to cover the tortious conduct of non-funded individual athletes. In making these claims, it is demonstrated how a sport-specific application of the doctrine may help to teach us a few broader lessons about vicarious liability more generally.
Multiple solutions for a class of quasilinear problems with double criticality
Authors: Ait-Mahiout Karima , Alves Claudianor O. , Garain Prashanta 
Published: October 2022

AbstractWe establish multiplicity results for the following class of quasilinear problems
P\begin{equation*} \left\{ \begin{array}{@{}l} -\Delta_{\Phi}u=f(x,u) \quad \mbox{in} \quad \Omega, \\ u=0 \quad \mbox{on} \quad \partial \Omega, \end{array} \right. \end{equation*}where $\Delta _{\Phi }u=\text {div}(\varphi (x,|\nabla u|)\nabla u)$ for a generalized N-function $\Phi (x,t)=\int _{0}^{|t|}\varphi (x,s)s\,ds$. We consider $\Omega \subset \mathbb {R}^{N}$ to be a smooth bounded domain that contains two disjoint open regions $\Omega _N$ and $\Omega _p$ such that $\overline {\Omega _N}\cap \overline {\Omega _p}=\emptyset$. The main feature of the problem $(P)$ is that the operator $-\Delta _{\Phi }$ behaves like $-\Delta _N$ on $\Omega _N$ and $-\Delta _p$ on $\Omega _p$. We assume the nonlinearity $f:\Omega \times \mathbb {R}\to \mathbb {R}$ of two different types, but both behave like $e^{\alpha |t|^{\frac {N}{N-1}}}$ on $\Omega _N$ and $|t|^{p^{*}-2}t$ on $\Omega _p$ as $|t|$ is large enough, for some $\alpha >0$ and $p^{*}=\frac {Np}{N-p}$ being the critical Sobolev exponent for $1< p< N$. In this context, for one type of nonlinearity $f$, we provide a multiplicity of solutions in a general smooth bounded domain and for another type of nonlinearity $f$, in an annular domain $\Omega$, we establish existence of multiple solutions for the problem $(P)$ that are non-radial and rotationally non-equivalent.
The hidden homeownership welfare state: an international long-term perspective on the tax treatment of homeowners
Authors: Kholodilin Konstantin A. , Kohl Sebastian , Korzhenevych Artem , Pfeiffer Linus 
Published: October 2022

AbstractWelfare is traditionally understood as social security decommodifying labour markets or as social investment policies. In the domain of housing, however, welfare for homeowners is largely hidden in the tax codes’ fiscal exemptions. Based on a content analysis of legislation, this article introduces a novel yearly database of 37 countries between 1901 and 2020 to uncover the “hidden welfare state” of taxes on imputed rent, deductibility of mortgage payments, housing capital gains tax, and value-added tax on newly built dwellings. Summary indices of homeownership attractiveness and neutrality of the tax code show that fiscal homeownership policies have been in decline until the 1980s and risen ever since. They are in place where finance is liberally and labour restrictively regulated. Contrary to the classical welfare state, they are not associated with an economic logic of industrialism or left-wing governments. They rather are an alternative to rent regulation used by Common-law jurisdictions or smaller countries. As welfare for property owners, the logic of fiscal homeownership welfare diverges from the classical welfare for the labouring classes.
Touching while listening: Does infants’ haptic word processing speed predict vocabulary development?
Authors: BEAUDIN Kayla , POULIN-DUBOIS Diane , ZESIGER Pascal 
Published: October 2022

AbstractThe present study examined the links between haptic word processing speed, vocabulary, and inhibitory control among bilingual children. Three main hypotheses were tested: faster haptic processing speed, measured by the Computerized Comprehension Task at age 1;11, would be associated with larger concurrent vocabulary and greater longitudinal vocabulary growth. Second, early vocabulary size would be associated with greater vocabulary growth at 3;0 and 5;0. Finally, faster haptic processing speed would be associated with greater concurrent inhibitory control, as measured by the Shape Stroop Task. The results revealed that haptic processing speed was associated with concurrent vocabulary, but not predictive of later language skills. Also, early decontextualized vocabulary was predictive of vocabulary at 3;0. Finally, haptic processing speed measured in the non-dominant language was associated with inhibitory control. These results provide insight on the mechanisms of lexical retrieval in young bilinguals and expand previous research on haptic word processing and vocabulary development.

SummaryThis study aimed to analyze the clinical effects of microdissection testicular sperm extraction (micro-TESE) surgery combined with an intracytoplasmic sperm injection (ICSI) regimen in the treatment of non-obstructive azoospermia (NOA) patients with different etiologies. In total, 128 NOA patients participated in this study, in which they received infertility treatment by micro-TESE surgery combined with an ICSI regimen, and all patients were divided into three groups [the Klinefelter syndrome (KS), the idiopathic and the secondary NOA groups]. In addition, the sperm retrieval rate (SRR), fertilization rate, embryo development status and clinical treatment effects were analyzed. Among the 128 NOA patients, the SRR of KS NOA patients was 48.65%, those of idiopathic and the secondary patients were 33.82% and 73.91%, respectively. Regardless of etiologies, there was no correlation with age, hormone value or testicular volume. Further analysis showed that the SRR of the KS group was positively related with testosterone (T) values, and the SRR of the secondary group had a positive relationship with follicle-stimulating hormone or luteinizing hormone values. In the subsequent clinical treatment, the retrieved sperm was subjected to ICSI and achieved good treatment effects, especially in the secondary group, and the implantation rate (55.56%) and clinical pregnancy rate (68.42%) were both higher than those of the idiopathic group (28.75% and 40.00%) and KS group (22.05% and 30.77%). Micro-TESE surgery combined with ICSI insemination is the most effective treatment regimen for NOA patients. The SRR of NOA patients with different etiologies are related to certain specific factors, and micro-TESE surgery seems to be the ideal and only way to have biological children.
Accuracy of Local Polarization Measurements by Scanning Transmission Electron Microscopy
Authors: Calderon Sebastian , Funni Stephen D , Dickey Elizabeth C 
Published: October 2022

Abstract
Accurately determining local polarization at atomic resolution can unveil the mechanisms by which static and dynamical behaviors of the polarization occur, including domain wall motion, defect interaction, and switching mechanisms, advancing us toward the better control of polarized states in materials. In this work, we explore the potential of atomic-resolution scanning transmission electron microscopy to measure the projected local polarization at the unit cell length scale. ZnO and PbMg1/3Nb2/3O3 are selected as case studies, to identify microscope parameters that can significantly affect the accuracy of the measured projected polarization vector. Different STEM imaging modalities are used to determine the location of the atomic columns, which, when combined with the Born effective charges, allows for the calculation of local polarization. Our results indicate that differentiated differential phase contrast (dDPC) imaging enhances the accuracy of measuring local polarization relative to other imaging modalities, such as annular bright-field or integrated-DPC imaging. For instance, under certain experimental conditions, the projected spontaneous polarization for ZnO can be calculated with 1.4% error from the theoretical value. Furthermore, we quantify the influence of sample thickness, probe defocus, and crystal mis-tilt on the relative errors of the calculated polarization.
Gigantoproductid shell spiral and microstructure of tertiary layer: evaluation as taxonomical characters
Authors: MATEOS-CARRALAFUENTE J. Ricardo , CORONADO Ismael , CÓZAR Pedro , RODRÍGUEZ Sergio 
Published: October 2022

ABSTRACTBrachiopod taxonomy is based on descriptions of shell morphology and key characters, but diagenesis generally modifies or erases some of them, hindering brachiopod identification. Brachiopods that are taxonomically related usually present shells with similar appearance but can differ in size (i.e., Rhynchonellata). Some aspects of morphology – for example the angular measurement of the curvature of the shell or details of shell microstructure – could aid taxonomic identification. Gigantoproductids, which lack a robust taxonomy, have the largest shells among brachiopods and are ideal for this kind of study because of their gigantic size and morphological variability. Furthermore, they have a great abundance and worldwide distribution during the mid-Carboniferous. More than 700 samples have been collected from Sierra Morena (Spain), Montagne Noire (France) and Adarouch (Morocco) identifying up to six gigantoproductid genera: Globosoproductus, Semiplanus, Kansuella?, Latiproductus, Gigantoproductus and Datangia. Microstructural features from 170 thin sections belonging to gigantoproductid ventral valves have been studied, and six crystal morphologies have been distinguished within the tertiary layer: subhorizontal, imbricated, crenulated, acicular, short and long columnar morphologies. Moreover, 23 complete shells from all genera have been selected to investigate shell size and curvature. Results from this study emphasise that shell size, curvature and crystal shape are taxa-related. Finally, a remarkable morphological change in the gigantoproductid populations from the western Palaeo-Tethys occurred during the Viséan–Serpukhovian, from thin-shelled genera with subhorizontal morphology (Viséan) to thick-shelled genera with a tertiary layer consisting of long columnar crystals (Serpukhovian). This study proves that microstructure, maximum thickness and shell spiral characterisation are robust characters when applied to gigantoproductid taxonomy, but also have great potential in other brachiopod groups.
Critical period of weed control in an interseeded system of corn and alfalfa

Published: October 2022

AbstractAlfalfa (Medicago sativa L.) hectares in Michigan are declining partly due to reliance on corn (Zea mays L.) silage as a continuous feed source. By interseeding corn and alfalfa, farmers can replace the low alfalfa yield in the establishment year with corn silage while simultaneously establishing alfalfa. A randomized split-block field study was conducted in East Lansing, MI, over 3 yr (2019 to 2021) to determine the critical period of weed control (CPWC) in the interseeded corn and alfalfa system using two corn hybrids with differing leaf architecture (pendulum vs. upright). Whole plots were assigned to corn hybrids interseeded with alfalfa, and subplots were assigned to a surrogate weed, Japanese millet [Echinochloa esculenta (A. Braun) H. Scholz], for the duration of competition treatments. Weed-free and weedy plots were included as controls. At the end of the interseeding year, corn was harvested, while alfalfa was harvested the following year. The CPWC is made up of two components: the critical timing of weed removal (CTWR) and the critical weed-free period (CWFP). Corn hybrid had no impact on the CTWR or CWFP for interseeded corn or alfalfa. Averaged across hybrids, the CTWR was 303 growing degree days (GDD), and CWFP was estimated to be greater than the study duration. The CTWR in the first cutting of alfalfa was estimated to be 369 GDD. The CWFP was estimated to be 394 GDD for a 5% acceptable yield loss for the first alfalfa cutting. Identification of the CPWC in the interseeded system will increase adoption and interest in other interseeded systems that can mitigate potential negative environmental and economic impacts of monoculture agriculture.
Disentangling Aerosol and Cloud Effects on Dimming and Brightening in Observations and CMIP6

Published: October 2022

AbstractPeriods of dimming and brightening have been recorded in observational datasets of surface solar radiation (SSR) between the mid‐20th century and present day. Atmospheric components affect SSR, including aerosols and clouds, though studies disagree somewhat about the relative effect of each component in different regions. Current Earth system models (ESMs) are unable to simulate observed trends in SSR. This study includes an investigation into observed SSR variations between 1961 and 2014 and an evaluation of the effects of cloud cover variations and impacts of aerosol extinction, using timeseries of SSR and cloud cover from in‐situ measurements. Historical simulations by 42 ESMs participating in the Coupled Model Intercomparison Project phase 6 (CMIP6) have also been studied and compared to observations. The observational study indicates that cloud cover has had a dampening effect on the variations of SSR and that emissions of aerosol and aerosol precursors are the main cause of the general trends in observed SSR in four regions—China, Japan, Europe, and the United States—during 1961–2014. The study of simulated SSR in CMIP6 yields the conclusion that current ESMs remain unable to simulate the magnitude of observed dimming and brightening in China, Japan, and the United States, but that the European SSR trends between 1961 and 2014 are fairly well reproduced in the ESMs. A rough quantification of the regional surface radiation extinction efficiency of aerosol and precursor emissions in the simulations is found to agree with observed values in Europe, but not in the other three regions.
