Resumo
Objetivo Correlacionar alterações radiográficas e lesões de estruturas intra-articulares do acetábulo com a intensidade da dor e a incapacidade de pacientes com diagnóstico de síndrome do impacto femoroacetabular.
Métodos Realiou-se uma análise retrospectiva de dados pré-operatórios de 182 pacientes (190 quadris). Foram avaliadas variáveis clínicas como idade, sexo e prática de atividade física, e variáveis radiográficas, como ângulo de Wiberg e o ângulo alfa. Por meio do vídeo intraoperatório, foi avaliada a extensão das lesões condrais e labiais considerando-se o método clock-face, o grau de comprometimento articular pela classificação de Outerbridge, e a presença de lesão em onda. As variáveis foram analisadas por meio de regressão linear, tendo como variáveis dependentes a intensidade da dor, avaliada pela Escala Visual Analógica (EVA), e a incapacidade funcional, mensurada pelo Harris Hip Score modificado (HHSm).
Resultados A média de idade dos pacientes foi de 38,5 ±  9,6 anos, a da intensidade da dor, 7,8 ±  1,6, e a do HHSm, 56,3 ±  12,7. No total, 61% da amostra apresentava Outerbridge III ou IV, e 12,6% apresentava lesão em onda. Observou-se correlação do sexo masculino (r = 0,497) com menor intensidade da dor, e correlação da idade (r = −0,27), do sexo masculino (r = 8,419) e da realização de atividade física com maior escore funcional no HHSm (r = 4,729).
Conclusão Não houve correlação dos parâmetros radiográficos e artroscópicos deste estudo com a intensidade da dor e a incapacidade dos pacientes. O sexo masculino está relacionado com menor intensidade da dor, e maior capacidade funcional está relacionada com o sexo masculino, menor idade, e a prática de atividade física.

Resumo
Objetivo Nosso objetivo foi estudar a resistência à extração “in vitro” do parafuso SpineGuard/Zavation Dynamic Surgical Guidance Z-Direct (Parafuso DSG Guia Cirúrgico Dinâmico, SpineGuard Inc, Boulder, Colorado, USA), um parafuso projetado para ser inserido utilizando a técnica de inserção direta.
Métodos Os parafusos DSG de 5,5 e 6,5 mm foram introduzidos em blocos de poliuretano com densidade de 10 PCF (0,16g/cm3). De acordo com o grupo experimental, os parafusos foram inseridos sem um orifício piloto, com um orifício piloto sem o macheamento, com macheamento e com macheamento linha a linha. Os testes de extração do parafuso foram realizados em uma máquina de teste universal, após a inserção do parafuso em blocos de poliuretano.
Resultados Os parafusos inseridos diretamente nos blocos de poliuretano sem o orifício piloto e o macheamento mostraram uma resistência à extração estatisticamente maior. A inserção do parafuso sem o macheamento ou com o macho de menor diâmetro aumenta a resistência à extração do parafuso em comparação com o macheamento linha a linha.
Conclusão O parafuso DSG apresentou a maior resistência à extração após a inserção sem o orifício piloto e o macheamento.

Published: January 2022

Background Endothelial and complement activation were both associated with immunothrombosis, a key determinant of COVID-19 severity, but their interrelation has not yet been investigated.
Objectives We aimed to determine von Willebrand factor (VWF) antigen (VWF:Ag) concentration, VWF collagen binding activity (VWF:CBA), a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS13) activity (ADAMTS13:Ac), and their ratios in hospitalized COVID-19 patients, and to investigate how these parameters and their constellation with complement activation relate to disease severity and in-hospital mortality in COVID-19.
Methods Samples of 102 hospitalized patients with polymerase chain reaction-confirmed severe acute respiratory syndrome coronavirus 2 positivity were included in our observational cohort study. Patients were stratified according to the peak severity of COVID-19 disease in agreement with the World Health Organization ordinal scale. Twenty-six convalescent plasma donors with previous COVID-19 disease formed the control group. VWF:Ag concentration and VWF:CBA were determined by enzyme-linked immunosorbent assay (ELISA); ADAMTS13:Ac was determined by fluorescence resonance energy transfer. Complement C3 and C3a were measured by turbidimetry and ELISA, respectively. Clinical covariates and markers of inflammation were extracted from hospital records.
Results VWF:Ag and VWF:CBA were elevated in all groups of hospitalized COVID-19 patients and increased in parallel with disease severity. ADAMTS13:Ac was decreased in patients with severe COVID-19, with the lowest values in nonsurvivors. High (> 300%) VWF:Ag concentrations or decreased (< 67%) ADAMTS13:Ac were associated with higher risk of severe COVID-19 disease or in-hospital mortality. The concomitant presence of decreased ADAMTS13:Ac and increased C3a/C3 ratio—indicating complement overactivation and consumption—was a strong independent predictor of in-hospital mortality.
Conclusion Our results suggest that an interaction between the VWF-ADAMTS13 axis and complement overactivation and consumption plays an important role in the pathogenesis of COVID-19.

AbstractBackground Artificial intelligence (AI) has been successfully applied in numerous scientific domains. In biomedicine, AI has already shown tremendous potential, e.g., in the interpretation of next-generation sequencing data and in the design of clinical decision support systems.Objectives However, training an AI model on sensitive data raises concerns about the privacy of individual participants. For example, summary statistics of a genome-wide association study can be used to determine the presence or absence of an individual in a given dataset. This considerable privacy risk has led to restrictions in accessing genomic and other biomedical data, which is detrimental for collaborative research and impedes scientific progress. Hence, there has been a substantial effort to develop AI methods that can learn from sensitive data while protecting individuals' privacy.Method This paper provides a structured overview of recent advances in privacy-preserving AI techniques in biomedicine. It places the most important state-of-the-art approaches within a unified taxonomy and discusses their strengths, limitations, and open problems.Conclusion As the most promising direction, we suggest combining federated machine learning as a more scalable approach with other additional privacy-preserving techniques. This would allow to merge the advantages to provide privacy guarantees in a distributed way for biomedical applications. Nonetheless, more research is necessary as hybrid approaches pose new challenges such as additional network or computation overhead.
How many roots of a system of random Laurent polynomials are real?
Authors: Kazarnovskii B. Ya. 
Published: January 2022

Abstract
We say that a zero of a Laurent polynomial that lies on the unit circle with centre

is real. We also say that a Laurent polynomial that is real on this circle is real. In contrast with ordinary polynomials, it is known that for random real Laurent polynomials of increasing degree the average proportion of real roots tends to

rather than to

. We show that this phenomenon of the asymptotically nonvanishing proportion of real roots also holds for systems of Laurent polynomials of several variables. The corresponding asymptotic formula is obtained in terms of the mixed volumes of certain convex compact sets determining the growth of the system of polynomials.

Turning traditionally nonwetting surfaces wetting for even ultra-high surface energy liquids
Authors: Wilke Kyle L. , Lu Zhengmao , Song Youngsup , Wang Evelyn N. 
Published: January 2022

Significance
Control over the interaction between liquids and surfaces is used in numerous thermofluidic systems, with behaviors ranging from highly repellent to highly wetting. In this work, we demonstrate that surface engineering enables highly wetting behavior from liquid/surface combinations that are typically nonwetting, broadening the design space for thermofluidic systems.
Perfective aspect and perfect aspect
Authors: Jin Lixin , Wang Wei , Xie Kun , Wang Xiaohua , Tang Xiaodong 
Published: January 2022

AbstractThe “perfective” (Chinese term:wánzhěngtǐ) and the “perfect”(Chinese term: wánchéngtǐ) seem to be two different terms that are distinguished by definition. But in the description of actual languages, the boundary between them is not clear. The use of these two terms in many literatures is very arbitrary. This arbitrariness frequently causes confusion in typological studies in tense and aspect. This arbitrary use has a lot to do with the classification and definition ofComrie (1976). Based on a description of the perfective/imperfective distinction in Russian, this paper finds that perfective is sensitive to the inner boundaries of events, and perfect is sensitive to the relation between event time and reference time. Based on a description of the four aspectual markers (zhe, le, guo, andzai) in Mandarin Chinese, this paper finds that they respectively express three different event phases (inchoative, durative and terminative) in realization aspect. The present study shows that Mandarin is not a language sensitive to boundaries of events, but to phasal aspect. Phasal aspect also exists in Japanese.
Asymmetries in two types ofde-related verb-copying constructionsin Mandarin Chinese
Authors: Wang Changsong 
Published: January 2022

AbstractThis article studies Chinese V-desentences from the perspective of verb-copying constructions (VCC) and presents some more evidence in favor of the distinction between descriptive V-deconstructions and resultative V-deconstructions. VCC with descriptive V-desentences (VCCD) and VCC with resultative V-desentences (VCCR) are linearly described as [NP1+ V1+ NP2 + V2 + de +XP]. Five asymmetries, though not very sharp, have been observed between VCCD and VCCR: (a) the movement asymmetry of [V1+NP2], (b) the questioning asymmetry betweenweishenme‘why’ andshenme‘what’, (c) the definiteness asymmetry of NP2, (d) the repetition asymmetry of V1, and (e) the asymmetry of subject-oriented adverbguyi‘intentionally’. To explain these differences, we assume that [V1+NP2] in VCCD is a constituent, acting as an internal topic. While similar analysis cannot be extended to VCCR. We propose instead that [NP1+V1+NP2] is a constituent in VCCR, projecting further into a complex NP and acting as a sentential subject. These structural differences can well explain the five asymmetries from the island effects, and the semantic and pragmatic constraints (on internal topics and subject-oriented adverbs). Meanwhile, based on the restriction of manner adverbial modification, the V2 in VCCD and VCCR is assumed to be externally merged at the morphological level via External Morphological Merger to satisfy the affixal properties ofde. The copying of V1 as V2 is not driven syntactically, but morphologically. This morphosyntactic approach to VCCD and VCCR provides a new perspective to explore V-desentences and VCC, which may shed light on the morphosyntactic studies of Mandarin Chinese from a crosslinguistic perspective.
The syntax and semantics of coherence relations
Authors: Crible Ludivine 
Published: January 2022

AbstractThis corpus-based study investigates the inter-relation between discourse markers (DMs) and other contextual signals that contribute to the interpretation of coherence relations. The objectives are three-fold: (i) to provide a comprehensive and systematic portrait of the syntax and semantics of a set of coherence relations in English; (ii) to draw a distinction between mere tendencies of co-occurrence and strong predictive signals; (iii) to identify factors that account for the variation of these signals, focusing on relation complexity, DM strength and genre preferences. The methodology combines systematic coding (description) and multivariate statistical modelling (prediction). While the effect of genre and relation complexity was found to be null or moderate, the presence of discourse signals systematically varies with the ambiguity of the DM in the relation: signals co-occur more with ambiguous DMs than with more informative ones.
Towards multilingualism in English‑medium higher education
Authors: Dafouz Emma , Smit Ute 
Published: January 2022

Abstract
Reflecting the global push for internationalisation, higher education institutions (HEIs) have experienced a surge
in English-medium education in multilingual university settings (EMEMUS). Of the many topics and angles pursued in the equally
vast research landscape, multilingualism has so far received comparatively less attention, especially when approached from the
perspective of students. By combining recent conceptualisations of multilingualism and of EMEMUS, this paper offers a qualified
literature review, discussing four research scenarios that foreground different student groups and some of their multilingual
experiences and practices. Based on the ROAD‑MAPPING framework, such discussions retain a level of detail that allows for a
comprehensive interpretation across scenarios, offering insights into the complexity and fluidity of multilingualism within
EMEMUS.
English language teaching and English-medium instruction
Authors: McKinley Jim , Rose Heath 
Published: January 2022

Abstract
The role of English language teaching (ELT) in English-medium instruction (EMI) can vary widely depending on education policy objectives and teachers’ responses to EMI students’ language and learning needs. In this paper, we provide a narrative review of a growing number of studies reporting language-related challenges as the foremost barrier to successful implementation of EMI. Such research highlights the fundamental roles that English for Academic Purposes (EAP) and English for Specific Purposes have in the provision of targeted language support for EMI students. Based on this review, we set a future research agenda, calling for explorations into the efficacy of English language programs for supporting EMI students to reach educational outcomes. We also call for explorations of greater collaboration between English language practitioners and content lecturers to ensure the right type of language support is being provided to students. The paper ends with a discussion for the need to reposition EAP as English for Specific Academic Purposes to ensure students’ specific academic needs are met. Essentially, universities offering EMI will need to account for their unique institutional characteristics to ensure ELT provision is central in organizational and curricular structures; otherwise, they may be setting their own students up to fail.
The communicative participation in pre-school children estimated by the FOCUS questionnaire
Authors: Piazzalunga Silvia , Salerni Nicoletta , Ambrogi Federico , Limarzi Sofia , Gianera Sabrina , Schindler Antonio 
Published: January 2022

Purpose
Participation-outcome measures are required in the phoniatric and speech-language pathology practice to evaluate real-life changes during interventions. In line with the bio-psycho-social model of health, ‘Focus on the Outcomes of Communication Under Six’ (FOCUS) is a validated scale by which parents rate their child’s Communicative Participation (CP). CP has been widely investigated in atypically-developing population, and it may be an innovative construct also for typically-developing children (TDC). The aim of the study is to describe the CP and its components observed in a large group of TDC, exploring whether children’s CP is influenced by their age.

Method
Through a cross-sectional observational study, parents of 355 Italian-speaking TDC aged 3.0–5.11 years without developmental impairments completed the Italian FOCUS (FOCUS-I).

Result
CP significantly increased with age (p < .001). Components’ scores differed by age, with some competences (‘pragmatics’, ‘receptive language/attention’, ‘social competence/play’, ‘coping strategies/emotions’) increased with age less than others (‘speech’, ‘intelligibility’, ‘independence’, ‘expressive language’).

Conclusion
The study suggests that a spontaneous significant increase in CP should be expected with a child’s development and it discusses the differences in the profile scores. When exploring real-life communicative participation, parents rate their children as changing mostly in their speech and expressive-linguistic competences.

Fountain fringe field switching (FFFS) for wide viewing angle LCDs
Authors: Komitov Lachezar , Barbero Giovanni , Ibn Elhaj Mohammed , Morawiak Przemysław , Piecek Wiktor 
Published: January 2022

Abstract
To reduce or completely remove the viewing angle dependence of liquid crystal (LC) displays and devices, we have recently introduced a new electrode structure for LC displays. This electrode structure has openings (holes) in the pixel electrode (PixE) for generating fringe electric field with azimuthal degenerated distribution of the field lines around each hole, resembling a fountain. Such a field is promoting azimuthally degenerated switching of the LC molecules and thus generation of images with 360° viewing angle constant contrast when a pair of crossed circular polarisers are used. A theoretical model of the fountain fringe field, generated around a single circular hole and plurality of such holes in the PixE, is presented.
Micromagnetic prediction strain and current co-mediated spindynamics in skyrmion-based spin-torque nano-oscillator
Authors: Cui Shuting , Zhu Mingmin , Qiu Yang , Guo Rongdi , Wu Guohua , Yu Guoliang , Zhou Haomiao 
Published: January 2022

Abstract
In this article, we theoretically investigate the influence of strain on the oscillation frequency characteristics of a skyrmion-based spin-torque nano-oscillator (STNO) using micromagnetic simulations. The system consists of an ultrathin nanopillar magnetic film with interfacial Dzyaloshinskii–Moriya interactions and a ring-shaped region to offer a tunable spatial strain source. The applied strain gives rise to an extra effective field in the magnetic film through magnetoelastic coupling and forms a strong confined potential for skyrmion dynamics. Our simulation results show that the operation frequency of the STNO can be effectively modulated by the strain. Furthermore, we introduce a simplified analytical expression of the skyrmion gyration dynamics to explain the micromagnetic simulation results. Our results will be useful in the development of wide-range frequency-tunable microwave emitters and frequency-shift keying for wireless communication.
Plasma re-activation: a promising approach to enhance chemical activity for plasma activated water

Published: January 2022

Abstract
Plasma activated water (PAW) is a green prospective solution for a wide range of biotechnology applications. However, the drawback for the transient chemical activity of PAW would make it lose versatility in possible applications. Herein, we propose a promising approach for plasma re-activation aimed at enhancing the chemical activity of PAW again before it entirely decays. Our results indicate that the PAW generated by re-activation displays superior physicochemical properties and higher production of RONS. Especially, the concentrations of ONOO−/O2
− and H2O2 by re-activation can remarkably increase by 17.88% and 34.83% compared to the initial activation, respectively. Furthermore, the low temperature storage shows excellent synergetic effects with re-activation, indicating that the re-activation actually enhances the chemical activity of PAW to a higher level. The possible reasons for high chemical activity of PAW by plasma re-activation may be affected by the synergistic effect of multi-factors including the residual RONS in stored PAW and the lower pH value, temperatures of electrode and liquid during re-activation. This study provides good insight into the nature of liquid chemistry for PAW prepered by plasma re-activation, and demonstrates a new alternative for improving the chemical activity of PAW.
Testing the superposition model in small CORSIKA shower simulations
Authors: Wibig Tadeusz 
Published: January 2022

Abstract
The idea of superposition in the high-energy interactions of cosmic ray nuclei and the development of extensive air showers initiated by them has been known for more than half a century. It has been thoroughly and successfully tested in a number of simulations for primary energies around 1015 and above. In this work, we will investigate its applicability to lower energies. At the lowest energies, when the shower contains on average about one charged particle (or even less), deviations from the superposition model can be seen in the simulation results. Fluctuations of higher moments of the main shower parameters are systematically broader than expected. Further studies to confirm superposition in particular in the shower longitudinal profile are in progress. A correct description of the longitudinal development of the small shower, a precise description of its fluctuations on the observational level with a correct implementation of the superposition principle will enable to construct a simple and fast phenomenological algorithm generating small showers indispensable for the interpretation of measurements made using a small local shower array and determination of the flux of single, incoherent, secondary cosmic ray particles.
