Authors: Giviziez Christiane Ricaldoni , Sanchez Eliane Gouveia de Morais , Lima Yanna Andressa Ramos de , Approbato Mário Silva 
Published: December 2021

Abstract
Objective It has been suggested that excess body weight could represent a risk factor for infertility outcomes. The present study aimed to evaluate the association of overweight and anovulation among infertile women with regular menstrual cycles.
Methods We conducted a retrospective case-control study with consistently anovulatory patients undergoing assisted reproduction treatment. The patients were stratified into normal weight (body mass index [BMI]: 18.5–24.9kg/m2) and overweight (BMI: 25.0–29.9kg/m2).Those with polycystic ovary syndrome or obesity were excluded. The groups were matched for age, duration of infertility, prolactin, follicle stimulating hormone (FSH), thydroid stimulating hormone (TSH), luteinizing hormone (LH), and estradiol levels.
Results Overweight was significantly associated with anovulation, when using the World Health Organization (WHO) criteria for anovulation: progesterone levels > 5.65 ng/ml and ultrasonography evidence of follicle collapse (odds ratio [OR]: 2.69; 95% confidence interval [CI95%]: 1.04–6.98).
Conclusion Body mass index above the normal range jeopardizes ovulation among non-obese infertile women with regular menstrual cycles.

Published: December 2021

Abstract
Objective To investigate the characteristics of women who had preterm birth (PTB) and related outcomes according to ethnicity.
Methods A secondary analysis of a multicenter cross-sectional study conducted in Brazil. Women who had PTB were classified by self-report as white and non-white. Clinical, pregnancy, and maternal data were collected through postpartum interviews and reviews of medical charts. The sociodemographic, obstetric and clinical characteristics of the women, as well as the mode of delivery and the neonatal outcomes among different ethnic groups were compared through a bivariate analysis.
Results Of the 4,150 women who had PTB, 2,317 (55.8%) were non-white, who were more likely: to be younger than 19 years of age (prevalence ratio [PR]: 1.05; 95% confidence interval [95%CI]: 1.01–1.09); to be without a partner; to live on low income; to have lower levels of schooling; to have ≥ 2 children; to perform strenuous work; to be from the Northeastern region of Brazil rather than the from Southern region; to have a history of ≥ 3 deliveries; to have an interpregnancy interval < 12 months; to have pregnancy complications such as abortion, PTB, preterm premature rupture of membranes (pPROM), and low birth weight; to initiate antenatal care (ANC) visits in the second or third trimesters; to have have an inadequate number of ANC visits; to be under continuous overexertion; to smoke in the first and second or third trimesters; and to have anemia and gestational hypertension. The maternal and neonatal outcomes did not differ between the groups, except for the higher rate of low birth weight (73.7% versus 69.0%) in infants born to non-white women, and the higher rate of seizures (4.05% versus 6.29%) in infants born to white women.
Conclusion Unfavorable conditions were more common in non-whites than in whites. Proper policies are required to decrease inequalities, especially in the context of prematurity, when women and their neonates have specific needs.
The nonlinear feedback dynamics of asymmetric political polarization

Published: December 2021

SignificancePolitical polarization threatens democracy in America. This article helps illuminate what drives it, as well as what factors account for its asymmetric nature. In particular, we focus on positive feedback among members of Congress as the key mechanism of polarization. We show how public opinion, which responds to the laws legislators make, in turn drives the feedback dynamics of political elites. Specifically, we find that voters’ “policy mood,” i.e., whether public opinion leans in a more liberal or conservative direction, drives asymmetries in elite polarization over time. Our model also demonstrates that once self-reinforcing processes among elites reach a critical threshold, polarization rapidly accelerates. By tying together elite and voter dynamics, this paper presents a unified theory of political polarization.

Published: December 2021

SignificanceCellular cryo-electron tomography suffers from severely compromised Z resolution due to the missing wedges of information not collected during the acquisition of tilt series. This paper shows that application of entropy-regularized deconvolution to transmission electron tomography substantially fills in this missing information, allowing for improved Z resolution and better interpretation of cellular structures.
Complex pathways and memory in compressed corrugated sheets
Authors: Bense Hadrien , van Hecke Martin 
Published: December 2021

SignificanceDescribing the response of materials is central to physics, yet the complex response of frustrated media—featuring multistep pathways which can be encoded by sequences of switching material bits—is poorly understood. Here we introduce compression of corrugated elastic sheets to experimentally observe and manipulate these bits, their interactions, and their pathways. We apply spatial gradients at the boundaries as a general technique to control the pathways. Besides mechanical memory, where the sheet remembers earlier extremal driving, we observe a pathway where interactions between material bits produce an elementary computation: counting to two. Our work paves the way for controlling material bits in other systems and suggests a tight link between computations and the complex response of frustrated matter.
Staying afloat
Authors: Walters Susan Gary 
Published: December 2021

Abstract
This qualitative study gives an emic account of the experiences of adult L2 learners studying Chinese characters. Using semi-structured interviews and written journals of Americans who have spent time in China, the study uncovers core experiences and common patterns, giving voice to the holistic experience of learners, including affective aspects. The results of the study show that the very complexity of Chinese characters simultaneously attracts and deters learners. Learners experience an ever-growing realization of deeper complexity and greater volume. The struggling that ensues compels learners to actively find strategies to enable them to remain afloat in the learning process: (1) breaking down the complexity, (2) managing the incoming volume, (3) finding satisfaction in using the learning, (4) leading their own learning, (5) making use of resources, and (6) maintaining their learning. Findings from this study suggest practical applications for both L2 learners and teachers of Chinese characters.

Abstract
For some decades, institutions such as galleries, libraries, archives, and museums (often abbreviated as GLAM institutions) have digitized numerous archival documents and made at least parts of these documents publicly available online. However, there is still a shortage of user-friendly and easily accessible interfaces for various user groups, especially regarding collections based on text sources. After a brief introduction to the research area and the project, this paper discusses a visualization and design study based on a selection of digitized archival material from the Ernst von Glasersfeld estate. We present a conceptual outline of this work and examples concerning discourse mapping, the analysis of argumentative structures as well as some didactical approaches. In so doing, conceptual backgrounds, educational material and design principles are outlined. The paper concludes with critical considerations as regards the limitations of the approaches discussed.
Considerations for predicting climate change implications on future spatial distribution ranges of ticks.
Authors: Raghavan Ram , Ganta Roman 
Published: December 2021

Abstract

This chapter focuses on spatial distribution models (SDMs) that are essential to producing reliable models of tick distributions, both in the present time and in the future, under climate change scenarios. It highlights the opinion that careful consideration of the methods is necessary in building SDMs, model assumptions, the limitations in predictions and making a careful interpretation of predictions, if possible, supported by field observations.
Climate change alone cannot explain altered tick distribution across Europe: a spotlight on endemic and invasive tick species.
Authors: Stachurski Frederic , Boulanger Nathalie , Blisnick Adrien , Vial Laurence , Bonnet Sarah 
Published: December 2021

Abstract

The effect of climate on the evolution of tick populations remains difficult to disentangle from other possible causes and undoubtedly varies depending on the region concerned and local tick species. Large-scale, long-term monitoring is, therefore, necessary to accurately assess climatic impact on tick populations. Climate change can alter tick populations, either indirectly by affecting vertebrate host populations or directly by increasing or decreasing their numbers. These ectoparasites, and in particular hard ticks, spend almost their entire life cycle in the external environment, thus climatic conditions influence their activity, viability and distribution. This expert opinion aims to illustrate the impact of climate change, and its association with other variables, on the distribution and abundance of tick populations in Europe using Ixodes ricinus and Hyalomma marginatum as typical examples of endemic and invasive species, respectively.
Climate-driven livestock management shifts and tick populations.
Authors: Titcomb Georgia 
Published: December 2021

Abstract

Climate change can affect all aspects of the tick life cycle, from altering host distributions to modulating tick development and survival. This expert opinion focuses on how humans can greatly affect tick populations via livestock management. This is likely to occur through at least three pathways: (i) by altering host abundance and composition; (ii) via habitat modification due to grazing and trampling; and (iii) by altering tick mortality via tick-control methods. Thus, climate-driven changes to livestock management can profoundly alter tick populations, especially in regions such as eastern and southern Africa, where high livestock density and worsening climate changes are coupled with high tick diversity and abundance.

It provides evidence and prediction of the climate change impact on the abundance, distribution and population dynamics of both ticks and tick-borne diseases.
Impact of climate change on co-feeding transmission.
Authors: Wu Jian-hong , Zhang Xue 
Published: December 2021

Abstract

Tick-borne pathogen co-feeding transmission is a non-systemic transmission in the tick-host enzootic cycle, through which the host provides a bridge between co-feeding susceptible and infected ticks to facilitate pathogen transmission. Co-feeding transmission requires co-feeding of susceptible ticks in close (both spatially and temporally) proximity to other infected ticks on the bridging host; hence, the contribution of co-feeding transmission to tick-borne pathogen transmission in the tick-host enzootic cycle is highly affected by environmental conditions. This expert opinion focuses on co-feeding transmission and infestation dynamics of ticks under changing climate conditions.

Authors: do Carmo Everton C. , Barroso Renato , Gil Saulo , da Silva Natalia R. , Bertuzzi Romulo , Foster Carl , Tricoli Valmor 
Published: December 2021

ABSTRACTThe effects of plyometric training (PT) on middle‐ and long‐distance running performances are well established. However, its influence on pacing behaviour is still unclear. The aim of this study was to evaluate the effects of PT on pacing behaviour. In addition, verify whether the adaptations induced by PT would change ratings of perceived exertion (RPE) and/or affective feelings during the race. Twenty‐eight male runners were assigned to two groups: control (C) and PT. PT held two weekly PT sessions for eight weeks. Drop jump (DJ) performance, 10‐km running performance, pacing behaviour, RPE and affective feelings, VO2peak, ventilatory thresholds (VT1 and VT2), peak treadmill speed (PTS), and running economy (RE) were measured. For group comparisons, a mixed model analysis for repeated measures, effect size (ES) and 90% confidence interval (90% CI) were calculated for all dependent variables. Significant differences pre‐to‐post was observed for PT group in DP (7.2%; p ≤ 0.01; ES = 0.56 (0.28–0.85)) and RE (4.5%; p ≤ 0.05; ES = −0.52 ((−0.73 to −0.31)) without changes in pacing behaviour. While PT was effective for improving DJ and RE, there is no evidence that pacing behaviour, RPE or affective feelings are directly affected by these adaptations during a 10‐km time trial run.
The angular pattern in the hyperfine structure of Xe I and Kr I atoms
Authors: Blondel C , Drag C 
Published: December 2021

Abstract
Recent reviews of the hyperfine structure of xenon and krypton have highlighted the variety of the values taken by the hyperfine coefficients A and B of these atoms. These variations, as functions of the atomic angular momenta, were however not explained quantitatively. This article shows the simple picture and angular momentum algebra that make it possible to account for the observed trend. The only necessary approximations are to consider the interaction of the outer electron negligible with respect to the coupling of the p
5 core with the nucleus, and to assume that the Racah

basis, conventionally used for the atomic states of noble gases, makes a fitting description of the hierarchy of their angular momentum couplings. The way the calculation corroborates the apparently erratic values of hyperfine coefficients A and B in Xe I and Kr I shows up as a confirmation of the validity of these approximations.
Terahertz interface physics: from terahertz wave propagation to terahertz wave generation
Authors: Du Wanyi , Huang Yuanyuan , Zhou Yixuan , Xu Xinlong 
Published: December 2021

Abstract
Terahertz (THz) interface physics as a new interdiscipline between the THz technique and condensed matter physics has undergone rapid development in recent years. In particular, the development of advanced materials, such as graphene, transitional metal dichalcogenides, topological insulators, ferromagnetic metals, and metamaterials, has revolutionized the interface field and further promoted the development of THz functional devices based on interface physics. Moreover, playing at the interface of these advanced materials could unveil a wealth of fascinating physical effects such as charge transfer, proximity effect, inverse spin-Hall effect, and Rashba effect with THz technology by engineering the charge, spin, orbit, valley, and lattice degrees of freedom. In this review, we start with a discussion of the basic theory of THz interface physics, including interface formation with advanced materials, THz wave reflection and transmission at the interface, and band alignment and charge dynamics at the interface. Then we move to recent progress in advanced materials from THz wave propagation to THz wave generation at the interface. In THz wave propagation, we focus on THz wave impedance-matching, Goos–Hänchen and Imbert–Fedorov shifts in THz region, interfacial modulation and interfacial sensing based on THz waves. In THz wave generation, we summarize ongoing coherent THz wave generation from van der Waals interfaces, multiferroic interfaces, and magnetic interfaces. The fascinating THz interface physics of advanced materials is promising and promotes novel THz functional devices for manipulating propagation and generation of THz waves at interfaces.

Published: December 2021

Abstract
Plasmon-induced transparency (PIT) is theoretically explored for a graphene metamaterial using finite-difference time-domain numerical simulations and coupled-mode-theory theoretical analysis. In this work, the proposed structure consists of one rectangular cavity and three strips to generate the PIT phenomenon. The PIT window can be regulated dynamically by adjusting the Fermi level of the graphene. Importantly, the modulation depth of the amplitude can reach 90.4%. The refractive index sensitivity of the PIT window is also investigated, and the simulation results show that a sensitivity of 1.335 THz RIU−1 is achieved. Additionally, when the polarization angle of the incident light is changed gradually from 0° to 90°, the performance of the structure is greatly affected. Finally, the proposed structure is particularly enlightening for the design of dynamically tuned terahertz devices.
Quantitative investigation of polarization-dependent photocurrent in ferroelectric thin films
Authors: Rani Komalika , Matzen Sylvia , Gable Stéphane , Maroutian Thomas , Agnus Guillaume , Lecoeur Philippe 
Published: December 2021

Abstract
Ferroelectric thin films are investigated for their potential in photovoltaic (PV) applications, owing to their high open-circuit voltage and switchable photovoltaic effect. The direction of the ferroelectric polarization can control the sign of the photocurrent through the ferroelectric layer, theoretically allowing for 100% switchability of the photocurrent with the polarization, which is particularly interesting for photo-ferroelectric memories. However, the quantitative relationship between photocurrent and polarization remains little studied. In this work, a careful investigation of the polarization-dependent photocurrent of epitaxial Pb(Zr, Ti)O3 thin films has been carried out, and has provided a quantitative determination of the unswitchable part of ferroelectric polarization. These results represent a systematic approach to study and optimize the switchability of photocurrent, and more broadly to get important insights on the ferroelectric behavior in all types of ferroelectric layers in which pinned polarization is difficult to investigate.

Published: December 2021

Abstract
Magnetic-field induced dynamic magnetoelectric coupling effects and polarization performance of Z-type Sr3Co2Fe24O41 (SCFO) ceramic has been investigated. Results found that SCFO’s transverse tapered magnetic structure can induce electric polarization, and its electric polarization direction will not change under external magnetic effects. First-order dynamic magnetoelectric coupling coefficient (α) and second-order dynamic magnetoelectric coupling coefficient (β) of SCFO exhibited strong response main in magnetic structural phase transition region. The magnetoelectric structural phase transition position appeared in low magnetic field, and the magnetic moment vector and its corresponding electric polarization vector of SCFO exhibited the most unstable state near its equilibrium position, which is beneficial for inducing strong dynamic magnetoelectric coupling response. When the applied magnetic fields to SCFO increased, the magnetic moment stability near the equilibrium position increased, and the dynamic magnetoelectric coupling response decreased. Results showed that the dynamic magnetoelectric coupling response of SCFO can bear T
1 = 370 K high temperature. The dynamic magnetoelectric coupling response induced by low magnetic fields in SCFO contributes to its actual application in next generation magnetoelectric information storage devices.
