AbstractObjectiveThe Repetitive Eating Questionnaire (Rep(eat)‐Q) is a brief self‐report measure developed to assess grazing behavior—an understudied problematic eating behavior associated with eating disorder psychopathology and poor weight management. This study aimed to adapt and test the psychometric properties and factor structure of the Rep(eat)‐Q in a Brazilian community sample.MethodWe used the International Test Commission guidelines for the adaptation of psychological measures between cultures. Participants were recruited from the community and on a university campus and completed a set of questionnaires including the Rep(eat)‐Q, psychological measures, and sociodemographic data.ResultsA total of 718 (86.4% female) completed the Rep(eat)‐Q and were eligible for the confirmatory factor analysis (CFA). Only 542 completed the entire survey (Rep(eat)‐Q and other psychological measures) and were eligible for the analysis of the validity evidence based on the relations to other variables. CFA revealed support for a two first‐order model as originally proposed, however, a hierarchical (i.e., second‐order) model is proposed. We found support for second‐order scalar invariance across sex. Both first‐ and second‐order internal consistency estimates presented very good evidence. Analysis (n = 542) revealed moderate to strong correlations (≥.58 to .77) between grazing (total score and subscales) and binge eating and other psychological measures, presenting good convergent evidence.DiscussionThis study reports good psychometric properties of the Rep(eat)‐Q for the Brazilian community sample.Public SignificanceGrazing is a problematic eating behavior and the Rep(eat)‐Q is one of the measures to assess grazing. The article aimed to adapt and test the psychometric properties of the Rep(eat)‐Q in a Brazilian community sample. The results support a two‐factor structure and suggest that the Rep(eat)‐Q possesses good psychometric properties to be used with the Brazilian populations.
Regeneration strategies and forest resilience to changing fire regimes: Insights from a Goldilocks model
Authors: Ramiadantsoa Tanjona , Ratajczak Zak , Turner Monica G. 
Published: March 2023

AbstractDisturbances are ubiquitous in ecological systems, and species have evolved a range of strategies to resist or rebound following disturbance. Understanding how the presence and complementarity of regeneration traits will affect community responses to disturbance is increasingly urgent as disturbance regimes shift beyond their historical ranges of variability. We define “disturbance niche” as a species' fitness across a range of disturbance sizes and frequencies that can reflect the fundamental or realized niche, that is, whether the species occurs alone or with other species. We developed a model of intermediate complexity (i.e., a Goldilocks model) to infer the disturbance niche. We parameterized the model for subalpine forests in Yellowstone National Park (USA) adapted to infrequent stand‐replacing fires and included the three major tree‐regeneration strategies: (1) obligate seeders that rely on ex situ seeding into burned areas (non‐serotinous lodgepole pine, Pinus contorta var. latifola), (2) obligate seeders that depend on in situ seedbanks (serotinous lodgepole pine, Pinus contorta var. latifola), and (3) species that can resprout from surviving roots following fire (quaking aspen, Populus tremuloides). Our results showed which regeneration strategies increase or decrease in prevalence as fire rotation declines. Non‐serotinous pines were extirpated when fire rotation was below 50 years in a monoculture and 100 years in a mixed forest; serotinous pines were extirpated when fire rotation was below 20 years; and aspen was extirpated when fire rotation fell below 6 years. The fundamental and realized disturbance niches pinpointed the key mechanisms limiting regeneration for each strategy, namely, increasing fire size for non‐serotinous pine (ex situ seeders), decreasing fire frequency for serotinous pine (in situ seeders), and interspecific competition for aspen (resprouters). In a mixed forest, the three regeneration strategies were complementary and each dominated at different combinations of fire size and frequency. Consequently, diversity of regeneration strategies enhanced forest resilience to declining fire rotations. Despite its simplicity, our Goldilocks model produced realistic dynamics and could be readily adapted to other disturbance‐prone ecosystems to explore the generality of these results. The disturbance niche is a key concept for anticipating community resilience to changing disturbance regimes.

AbstractWe present a case of a 47‐year‐old woman with a history of asthma and mononeuritis who presented with shortness of breath and fatigue. Heart failure was diagnosed and echocardiography revealed large floating thrombi attached to the left ventricular walls. Cardiac magnetic resonance imaging showed evidence of myocarditis and angiitis. Blood count revealed eosinophilia. She was diagnosed with eosinophilic granulomatosis with polyangiitis or Churg–Strauss syndrome (CSS) according to recently updated criteria. Medical management with specific aetiology (anticoagulation or immunosuppression) and heart failure treatment resulted in clinical improvement. We further discuss the diagnostic approach of CSS with cardiovascular complications and therapeutic management.

Published: March 2023

AbstractAimsHeart failure (HF) is a progressive disease in which periods of clinical stability are interrupted by episodes of clinical deterioration known as worsening heart failure (WHF). Patients who develop WHF are at high risk of subsequent death, rehospitalization, and excessive healthcare costs. As such, WHF could be seen as a separate disease stage and precursor of advanced HF. Whether WHF has a substantial health, societal, and economic impact evidence regarding its multifactorial nature and the specific barriers in treatment, including advanced HF therapies, remains scarce. The CHAIN‐HF registry aims to describe the incidence, characteristics, current treatment, and outcomes of WHF. Additionally, it will promote structured regional collaboration and educate on increasing awareness for WHF and describe the implementation of guideline directed medical therapy and utilization of advanced HF therapies in a collaborative network.Methods and resultsThe CHAIN‐HF registry is a prospective, observational, and multicentre study from the collaborating hospitals (Rijnmond HF Network) in the Rotterdam area. Unselected and consecutive patients (irrespective of ejection fraction) with a WHF event will be included. Comprehensive data including demographics, co‐morbidities, treatment, and in‐hospital and post‐discharge outcomes will be collected. Notably, data on socio‐economic status, treatment decisions, and referral for advanced HF therapies will be included.ConclusionsCHAIN‐HF will be the first prospective, dedicated WHF registry in a collaborative network of hospitals that will provide robust real‐world evidence on the incidence, characteristics, and outcomes of WHF. Moreover, it will provide information on of the value of regional collaboration to improve awareness and outcomes of WHF.

Published: March 2023

AbstractHerein we report the syntheses of highly rigid silicon‐ and tin‐containing cyclic and bicyclic compounds with unsaturated organic backbones. The syntheses proceed via di‐lithiated diethynylbenzene derivatives. The protocols for the known precursor compounds were significantly improved in a two‐step one‐pot reaction with yields up to 45 % by alternating addition of the lithiation reagent and starting material. A total of ten compounds were synthesized and the molecular structure in the solid state was elucidated for six novel compounds. Host‐guest‐experiments with selected molecules were conducted to investigate on the potential of the complexation of small anions. All compounds were characterized by multinuclear NMR spectroscopy and elemental analyses or mass spectrometry and in most parts by SC‐XRD analyses.
Nickel Molybdenum Bimetallic Nitrides as Efficient Catalysts for the Hydrodeoxygenation of Methyl Palmitate
Authors: Zhao Chenxi , Wang Jiequan , Chen Xiao , Liang Changhai 
Published: March 2023

AbstractHighly efficient catalysts play an important role in the effective use of biomass oil to produce clean fuel. In this work, pure‐phase Ni−Mo bimetallic nitrides (Ni2Mo3N and Ni3Mo3N) with different stoichiometric ratios are prepared by temperature‐programmed nitridation of the metal oxide precursors in ammonia, which are investigated in the hydrodeoxygenation of methyl palmitate in the fixed‐bed reactor at moderate conditions. The physical and chemical properties of catalysts were evaluated by H2‐TPR, XRD, SEM, TEM, XPS, and CO chemisorption. The Ni2Mo3N catalyst presents the best methyl palmitate hydrogenation activity (con.%=95.4 %) and the maximum hexadecane selectivity (95.0 %), which is obviously higher than those of Ni3Mo3N and Mo2N catalysts. By introducing transition metal Ni into the Mo2N lattice to form nickel‐molybdenum bimetallic nitride, the lattice structure and electronic structure of the Mo active center have been changed, which greatly enhances the hydrodeoxygenation performances for the transformation of biomass oil to clean fuel.
Evolution of mixing length empirical equation for recouping of heat from industrial waste flue gases using air‐quarry dust/iron ore
Authors: Kaki Pramod , Popuri Ashok Kumar 
Published: March 2023

AbstractIndustry processes require large amounts of energy inputs and often generate high temperatures exit gases that can potentially serve as secondary sources of energy. Waste heat recovery offers an opportunity for energy conservation that deserves more attention in the current global effort. Recovery of such waste heat can result in substantial reductions in net energy demand. Based on these objectives, this report describes the result of an experimental study that used solid particles in a vertical riser to recover gas energy from hot air through co‐current contact with solid particles. To study the hydrodynamic aspects of the riser section, this study utilized a fabricated experimental apparatus similar to the vertical duct used in the cement industry. The purpose of this study is to collect hydrodynamic data because there is limited information available about these aspects in the literature. A metallic fluid particle heat exchanger has been investigated through experiments. Various sizes of quarry dust and iron ore particles are studied in the present study. An empirical correlation is used to fit the mixing length (LA) determined at different parametric levels (gas velocity, particle size, solid feed rate, and solid density). Experimental correspondence for mixing length or LA is given as . The constructed experimental setup demonstrates a suspension preheater (SP) used in modern cement plants, but the correlation can be extended to a variety of other industries where waste heat recovery is feasible.
A performance‐based seismic loading protocol: The generated sequential ground motion
Authors: Golestani Maryam , Alam M. Shahria , Calvi Gian Michele 
Published: March 2023

AbstractA realistic performance‐based seismic loading protocol called generated sequential ground motion (GSGM) has been developed in this paper. GSGM is a ground motion fabricated from segments of real recorded ground motions that could enable the introduction of performance‐based seismic assessment and design to experimental testing in setups such as shaking table testing. It can also significantly reduce the number of nonlinear time history analyses required in performance‐based seismic design. The protocol optimizes the behavioral information output of an experimental test or numerical analysis by incorporating dynamic demands corresponding to design limit states with different probabilities of exceedance (i.e. 10%, 5%, and 2% in 50 years) in a single record. In addition, since the segments are matched to relevant target spectra, the number of ground motions required to estimate the mean response is reduced. This paper presents the algorithm developed to produce the GSGM. The capability of the GSGM to replicate the structural responses produced by code‐compliant suites, and a suite of 100 ground motions as a more robust estimation of the actual response is investigated. The results of the case study bridge pier show that the drift variation of the GSGMs compared to code‐compliant suites is within 10%. Compared to the estimate of the actual response, the drift variation of GSGMs and the code‐compliant suites is 20% and 15%, respectively, and the damage variation is 30% and 15%, respectively. Furthermore, considering other relevant intensity measures when producing GSGMs can reduce these variations. This study suggests that the GSGM can replicate structural responses of the current code procedures.
Geophysical surveys for non‐invasive characterization of sinkhole phenomena: A case study of Murisengo
Authors: Bonetto Sabrina Maria Rita , Caselle Chiara , Comina Cesare , Vagnon Federico 
Published: March 2023

AbstractThe present research investigates the morphology and genetical mechanism of a sinkhole which occurred in 2019 in Murisengo (NW Italy). This landform is representative of several subsidence phenomena that often concern the Monferrato area (NW Italy). In concomitance with the appearance of the sinkhole at the surface, a cone of detrital material was found in the drifts of a nearby underground quarry. A geological survey was performed in the underground quarry in order to understand the interaction between the geological and geostructural features of the rock body and the generation of the sinkhole. Moreover, the underground sinkhole morphology was investigated through electrical resistivity tomography (ERT) surveys performed at the surface. The ERT outputs were combined to obtain a 3D image of the phenomenon and the 3D reconstruction was then compared with the geomorphological and structural setting of the area. Results suggest that a viscoplastic flow of clay‐rich sediments within a conduit in the gypsum bedrock (suffusion process) generated the sinkhole.

Published: March 2023

AbstractIn this paper, three‐transmit antennas uncoded space‐time labeling diversity (USTLD) scheme in arbitrarily correlated Nakagami‐fading channels are presented. The authors apply eigenfilter decomposition technique to synthesize the average branch signal‐to‐noise ratio (SNR), while deriving the theoretical probability density function (PDF) for the channel. The analytical mean bit error rate (BER) for the correlated channel was formulated using the moment generating function based on a virtual branch approach. Monte Carlo simulations are used to validate the derived analytical expression, which converge tightly at high values of SNR. Based on the decorrelation transformation technique, a further investigation of the USTLD scheme was performed in identically distributed fading channels. The results in this paper indicate that the best error performance is observed when the antenna spacings are 0.4for the 16QAM and 64QAM constellations respectively, whereis the antenna spacing distance. Simulations for the USTLD scheme with different values ofindicate that as the value forincreases, the error performance improved. Additionally, it can be seen that in similar conditions, the USTLD scheme in the identically distributed fading channels had illustrated an improved error performance over the traditional multiple‐input multiple‐output (MIMO) scheme respectively.

AbstractThe formation and release of eggs during ovulation are impacted by high amounts of androgens. Seed cycling is powerful in the treatment of polycystic ovary syndrome (PCOS). For efficacy studies, 90 women with PCOS, between 15 and 40 years were selected from the department of gynecology, Tertiary care unit. Women with PCOS were divided into three groups (T0, T1, T2) (20 women/group). Among these three groups, the first was the control group (T0). The second group was the experimental group (T1). In T1, 20 women with PCOS were treated with a portion control diet and METFORMIN 500 mg tab/day for 90 days. The third group was also an experimental group (T2). In this group, 20 women with PCOS were also treated with another treatment plan for 90 days, in which portion control diet and seed cycling were included. During the 12‐week efficacy trial, the highest follicle stimulating hormone (FSH) levels were found in the control group T0 (8.18 ± 0.13 mIU/mL). In T2, FSH falls from 6.545 ± 0.16 mIU/mL to 3.51 ± 0.13 mIU/mL throughout a 12‐week period. Overall, a portion‐controlled diet and seed cycling reduced FSH levels by 1.2% to 2.5%. LH value was 10.118 ± 0.1874 IU/L in the control group (T0), which climbed 12.82 ± 0.15 IU/L, but decreased from 10.62 ± 0.26 IU/L to 9.79 ± 0.17 U/L and 11.015 ± 0.24 IU/L 6.217 ± 0.167 IU/L in the other groups (T1, T2). It was determined that the LH levels were reduced by 1.5%–2% in T2. Conclusively, the seed cycling approach is effective and has significant results in women with PCOS. Seed cycling improves hormonal disturbance in women which promotes a healthy life.
Strategic trading and manipulation in trade at settlement contracts
Authors: Pirrong Craig 
Published: March 2023

AbstractTrade at settlement (“TAS”) contracts are widely employed by futures exchanges. They are an example of a “derived pricing” mechanism that reduces the transactions costs of uninformed traders. However, TAS contracts are susceptible to strategic, and indeed manipulative, trading by large intermediaries. Those with large TAS positions can profit from trading strategically/manipulatively, and this trading tends to cause excessive price movements. Moreover, some of the price impacts of such strategic trading are permanent. The severity of strategic/manipulative trading and its effects depends on the concentration of TAS positions, and information on concentration and price movements can be used to detect such trading.
Global strategy collections: Multinationality and performance
Authors: Pedersen Torben , Tallman Stephen 
Published: March 2023

AbstractResearch SummaryIn this second collection of articles relating to global strategy, we address the well‐established but unresolved issue of the relationship between multinationality and performance among multinational firms. The M‐P relationship has been the topic of many articles in many journals for many years, but its true nature is still not established. Both theory and empirical findings provide different and often opposed views, as can be seen in the articles collected here. We see two main perspectives on this issue. Some scholars suggest that differences in data and analytical tools have prevented consistent empirical results, and that more consistent and carefully chosen empirical modeling can yet establish the true M‐P connection. Others believe that basic problems in theory and in building testable frameworks that are truly consistent with theory have made this an inherently intractable problem. The collection provides important articles that test the M‐P relationship as well as critiques from both perspectives. We see considerable power in the view that individual firms are likely to have their own idiosyncratic optimal level of multinationaliation. We finish by calling for and suggesting new approaches to the issue, such as a micro‐foundations approach, as opposed to simply using more sophisticated tools to test problematic models based on well‐established but ultimately inadequate theory.Managerial SummaryThe relationship between the level of multinational diversification and performance in multinational firms is at the heart of global strategy. If operating at ever increasing levels in ever more countries does not provide reliably superior performance, why do firms continue to expand internationally? One view suggests that since firms continue to increase their international presence, there must be some ultimate benefits—difficult as they may be to establish. The opposing view suggests that since an equal amount of research finds no such benefits, it may be that no level of multinational diversification is generally optimal, but that depending on its particular resources and capabilities, experience, industry, and national portfolio, each multinational must discover its own optimal level of cross‐border investment.
