Numerical Study on the Aerodynamic Performance of the Rigid and Corrugated Forewing of Dragonfly in Flapping Flight
Authors: Song H , He G Y , Wang Q , Chen L S 
Published: June 2020

Abstract
The dragonfly flapping flight as a kind of important flight model, in order to explore the aerodynamic effect on the forewing of dragonfly in flapping. Based on the real dragonfly wings(with corrugation 3D forewing), this paper uses X-flow software numerical simulation for the model, analyzed the influence of different flow velocity and frequency on the aerodynamic effect of the forewing of dragonfly. When the dragonfly flies forward stably, the results show that it has a higher lift with the increase of inflow velocity and flapping frequency. The leading edge vortex (LEV) of the dragonfly’s forewing does not fall off in a flapping period, and the maximum positive lift is generated in the downstroke. When the trailing edge vortex is strong, the peak value of thrust coefficient appears in the process of flapping, and the energy of the trailing edge vortex may provide the thrust for the dragonfly forward flight.

Published: June 2020

Abstract
In this study, the Computational Fluid Dynamics code in SolidWorks was used to predict the aerodynamic coefficients of 122 mm rocket in order to get more accurate aerodynamic coefficients and derivatives for flight simulation. This paper presented the governing equations of fluid dynamics applied in SolidWorks and developed the computational model of the rocket. The results were compared against calculated data from an empirical method. The conducted analyses showed that the comparison results are nearly the same. However, the empirical method provided a faster way to obtain results.
Effects of a Splitter and an Endplate on Flow-induced Vibration Characteristics of Cantilevered Rectangular and D-section Prisms
Authors: Ahmad Barata La Ode , Kiwata Takahiro , Kono Takaaki , Ueno Toshiyuki 
Published: June 2020

Abstract
The effects of a splitter and an end plate on the flow-induced vibration characteristics of cantilevered rectangular and D-section prisms with the different finite lengths (aspect ratios L/H) and depth ratios (side ratio D/H of 0.2 and 0.5) have been investigated in a water tunnel. In order to suppress the alternating vortex shedding in the wake of buff bodies, a splitter plate was installed behind the prisms with a small gap and sufficient length to prevent vortex shedding intrusion. Meanwhile, to maintain a two-dimensional flow structure, an endplate was attached to the prism tip end. Mounting the splitter plate enhanced the response amplitude for all prisms. In this case, interferences of amplitude signal spectra for the period of displacement vanished on the prism with a side ratio of 0.5 yielding a uniform waveform on response amplitude. The attached endplate does not take an important role in enhancing the dynamic response of the prisms with a side ratio of 0.5 but it suppressed the response amplitude of prisms with D/H = 0.2.

Authors: Kuang T F , Qin H B , Liu F M , Li Q , Yue X , Gao H T , Yi Y Y 
Published: June 2020

Abstract
Because of the excellent mechanical property at high temperature, single-crystalline Ni3Al-based alloys, which belong to Ni-based superalloys, are widely adopted in the fields of aerospace, aviation and military. Usually, single-crystalline Ni-based alloys are bonded or welded together by polycrystalline Ni-based alloys. In this study, the Young’s modulus, shear modulus, bulk modulus, and Poisson ratio of polycrystalline Ni3Al at the temperature ranging from 10 °C to 850 °C were calculated according to Voigt–Reuss approximation, and the relationships between the mechanical properties and the temperatures were clarified. Moreover, the influence of temperature on the universal anisotropy index and mechanical properties of single-crystalline Ni3Al was evaluated. Results show that, except for Poisson ratio, the increase of temperature linearly decreases the mechanical properties of polycrystalline Ni3Al, while it increases the universal anisotropy index of the single-crystalline Ni3Al. Moreover, different with the bulk modulus, the Young’s modulus and shear modulus of single-crystalline Ni3Al are obvious anisotropic, and their anisotropic characteristics are quite opposite. The increasing temperature decreases both maximum and minimum values of Young’s modulus, shear modulus, and bulk modulus of single-crystalline Ni3Al.
Effect of different microstructure on dynamical stab-resistant property of TA15 alloy
Authors: Ruining Wang , Ruijun Sun , Lingjie Yu 
Published: June 2020

Abstract
The effects of different microstructure on the dynamical stab-resistant property of TA15 alloy are investigated. The specimens were tested on the stab apparatus after heat treatment at temperature of 850, 930 and 1030°C, time of 30min and air cooled. The impact force-time curves, microstructure and fracture morphology of specimens were analyzed. The results showed that the properties of higher strength and plasticity are benefit to the performance of stab resistance of TA15 specimens, and the curves of 930°C and 850°C exhibit two peaks and longer time ranges, but the curve of 1030°C exhibits the shortest time to reach the peak of impact force, and the specimens heat treated at 850°C exhibit the better performance against the knife impactor because of fine grain and stronger grain boundary binding force to absorb the impact force energy.

Published: June 2020

Abstract
The fundamental problem considered in this paper is the choice of materials, in this case stainless steels, for a particular industrial purpose. The choice of the appropriate material should be made based on the material behavior database established by experimental investigations. The mechanical behavior and mechanical properties of several stainless steels, such as ferritic, martensitic and austenitic stainless steels are investigated and analyzed in this research. Mechanical properties at room and high temperatures, creep behavior at different high temperatures and different stress levels as well as Charpy fracture impact energy were considered for several of the steels mentioned. Fracture toughness, based on the Charpy impact energy is calculated using known analytical procedure. In this sense, material properties are determined based on displayed engineering stress-strain diagrams while material creep behavior is displayed in the form of creep curves. Some of numerical values regarding the ultimate tensile strength, measured at room temperature, are given using the following order and in the following form: [σm, Mat.Nr
]20°C. In this sense, the stress levels of the u are: [9251.4122; 7821.4034; 7261.4305; 6861.4841; 5851.4762; 6071.4541]20°C.
Utilisation of Eggshell Powder (ESP) as Partial Replacement of Cement Incorporating Superplasticizer
Authors: Vasudevan Gunalaan , Chan Wei Seah 
Published: June 2020

Abstract
This research showed the results of experiments evaluating the use of eggshell powder from egg production industry as partial replacement for ordinary Portland cement. Research on the reuse of waste materials in the concrete industry has been quite intensive in the past decade. The objective of this research is to identify the performance of dried eggshell powder as a partial cement replacement in the production of concrete. Eggshell powder of various amounts, namely 5%, 10%, 15% and 20% by volume, was added as a replacement for ordinary Portland cement. The results showed that eggshell concrete greatly improved the compressive and flexural strength of concrete. The rate of water absorption of eggshell concrete was reduced as eggshell powder filled up the existing voids, making it more impermeable. However, the compressive strength of the eggshell concrete decreases gradually when the amount of eggshell powder increased. It can be concluded that the optimum percentage of dried eggshell powder as a partial cement replacement is 15%. In this direction, an experimental investigation of ultrasonic pulse velocity, rebound hammer concrete test, compressive strength, flexural strength and FTIR spectra and TGA analysis was undertaken to use eggshell powder and admixtures as partial replacement for cement in concrete.
Direct measurement methods of density matrix of an entangled quantum state
Authors: Turek Yusuf 
Published: June 2020

Abstract
In general, the state of a quantum system represented by the density operator and its determination is a fundamental problem in quantum theory. In this study, two theoretical methods such as using postselected measurement characterized by modular value and sequential measurements of triple products of complementary observables to direct measurement of matrix elements of density operator of a two photon entangled quantum state are introduced. The similarity and possible feasibilities of those two methods are discussed by considering the previous theoretical and experimental works.
Weight-Related Information Avoidance Prospectively Predicts Poorer Self-Monitoring and Engagement in a Behavioral Weight Loss Intervention
Authors: Schumacher Leah M , Martinelli Mary K , Convertino Alexandra D , Forman Evan M , Butryn Meghan L 
Published: June 2020

Abstract

Background
Self-monitoring is a key component of behavioral weight loss (BWL) interventions. Past research suggests that individuals may avoid self-monitoring in certain contexts (e.g., skipping self-weighing after higher-than-usual calorie intake). However, no studies have attempted to quantify individuals’ inclination to avoid information about their weight control (“weight-related information avoidance”; WIA) or prospectively examined its implications for treatment engagement and outcomes in BWL programs.

Purpose
Characterize WIA using a validated questionnaire among adults enrolled in BWL treatment and examine whether WIA prospectively predicts self-monitoring adherence, session attendance, treatment discontinuation, or weight loss.

Methods
Participants (N = 87; MBMI = 34.9 kg/m2, 83% female) completed a measure of WIA prior to starting a 12 week, group-based BWL intervention. Participants were given digital self-monitoring tools and instructed to self-monitor their food intake daily, physical activity daily, and body weight weekly (Weeks 1–10) and then daily (Weeks 11–12). Session attendance and treatment discontinuation were recorded. Weight was measured in-clinic pretreatment and posttreatment.

Results
While mean WIA was low (M = 2.23, standard deviation [SD] = 0.95; potential scale range: 1–7), greater WIA predicted poorer attendance (r = −.23; p = .03) and poorer self-monitoring of physical activity (r = −.28; p = .009) and body weight (r = −.32; p = .003). WIA did not predict food monitoring (p = .08), treatment discontinuation (p = .09), or 12 week weight loss (p = .91).

Conclusions
Greater WIA, as assessed via a brief questionnaire, may place individuals at risk for poorer self-monitoring and treatment engagement during BWL. Further research on the implications of WIA in the context of weight management is warranted, including evaluation of correlates, moderators, and mechanisms of action of WIA.

Prime Movers: Effects of Subliminal Primes, Music, and Music Video on Psychological Responses to Exercise
Authors: Pottratz Suzanne T , Hutchinson Jasmin C , Karageorghis Costas I , Mullin Elizabeth M , Zenko Zachary 
Published: June 2020

Abstract

Background
Priming is a process in which exposure to a stimulus activates relevant mental representations that are given increased weight in subsequent judgment tasks. Affective primes can influence affective evaluations and associations. Such influence has meaningful implications for the promotion of exercise behavior, yet there is scant research on priming effects in exercise settings.

Purpose
The purpose of the present pair of studies was to examine the efficacy of music (M), music video (MV), and music video with affective primes (PRIME) in modulating psychological responses during and immediately following an exercise bout among two distinct populations.

Methods
In Study 1, physically active participants completed a brisk walking task on a treadmill under four conditions: M, MV, PRIME, and control. Affective valence and rating of perceived exertion (RPE) were assessed during exercise and remembered/forecasted pleasure was measured immediately following each exercise bout. In Study 2, largely inactive and overweight participants completed a brisk walking task on a treadmill under two conditions: MV and PRIME. Affective valence was assessed during exercise, while exercise enjoyment and remembered/forecasted pleasure were assessed postexercise.

Results
In Study 1, PRIME yielded more positively valenced affect, remembered/forecasted pleasure, and lower RPE when compared to the other conditions (MCohen’s d for all DVs = 0.91). In Study 2, PRIME elicited more positively valenced affect, greater enjoyment, and enhanced remembered/forecasted pleasure when compared to MV (MCohen’s d for all DVs = 0.64).

Conclusions
Subliminal primes embedded in music video can elicit positive changes in psychological responses during and immediately following exercise.

AbstractMembrane proteins are unique in that they interact with lipid bilayers, making them indispensable for transporting molecules and relaying signals between and across cells. Due to the significance of the protein’s functions, mutations often have profound effects on the fitness of the host. This is apparent both from experimental studies, which implicated numerous missense variants in diseases, as well as from evolutionary signals that allow elucidating the physicochemical constraints that intermembrane and aqueous environments bring. In this review, we report on the current state of knowledge acquired on missense variants (referred to as to single amino acid variants) affecting membrane proteins as well as the insights that can be extrapolated from data already available. This includes an overview of the annotations for membrane protein variants that have been collated within databases dedicated to the topic, bioinformatics approaches that leverage evolutionary information in order to shed light on previously uncharacterized membrane protein structures or interaction interfaces, tools for predicting the effects of mutations tailored specifically towards the characteristics of membrane proteins as well as two clinically relevant case studies explaining the implications of mutated membrane proteins in cancer and cardiomyopathy.

Preclinical contraceptive development for men and women
Authors: Johnston Daniel S , Goldberg Erwin 
Published: June 2020

AbstractThis manuscript endeavors to present research considerations for the preclinical development of non-hormonal contraceptives. Topics include (1) how advances in genomics and bioinformatics impact the identification of novel targets for non-hormonal contraception, (2) the importance of target validation prior to investment in a contraceptive development campaign, (3) considerations on targeting gametogenesis vs gamete maturation/function, (4) how targets from the male reproductive system are expanding women’s options for ‘on demand’ contraception, and (5) some emerging non-hormonal methods that are not based on a specific molecular target. Also presented are ideas for developing a pipeline of non-hypothalamic-pituitary-gonadal-acting contraceptives for men and women while balancing risk and innovation, and our perspective on the pros and cons of industry and academic environments on contraceptive development. Three product development programs are highlighted that are biologically interesting, innovative, and likely to influence the field of contraceptive development in years to come.

AbstractMalnutrition linked to poor quality diets affects at least 2 billion people. Forests, as well as agricultural systems linked to trees, are key sources of dietary diversity in rural settings. In the present article, we develop conceptual links between diet diversity and forested landscape mosaics within the rural tropics. First, we summarize the state of knowledge regarding diets obtained from forests, trees, and agroforests. We then hypothesize how disturbed secondary forests, edge habitats, forest access, and landscape diversity can function in bolstering dietary diversity. Taken together, these ideas help us build a framework illuminating four pathways (direct, agroecological, energy, and market pathways) connecting forested landscapes to diet diversity. Finally, we offer recommendations to fill remaining knowledge gaps related to diet and forest cover monitoring. We argue that better evaluation of the role of land cover complexity will help avoid overly simplistic views of food security and, instead, uncover nutritional synergies with forest conservation and restoration.
Safe Haven or Dangerous Place? Stereotype Amplification and Americans’ Perceived Risk of Terrorism, Violent Street Crime, and Mass Shootings
Authors: Haner Murat , Sloan Melissa M , Pickett Justin T , Cullen Francis T 
Published: June 2020

AbstractPeople overestimate the risk of some events, such as terrorist attacks and immigrant crimes, but not of others. Stereotype amplification theory indicates that politicized, out-group stereotypes may be to blame. We examine Americans’ perceptions of the risk that different forms of violence—out-group, in-group and non-racialized—will occur in their local communities. We hypothesize that negative stereotypes of immigrants and Muslims will increase the perceived risk of out-group violence but not of other forms of violence. Analyses of original survey data from a sample of 1,068 Americans reveal four findings: (1) most Americans accurately perceive home-grown violence to be more likely than violence by foreigners, (2) political identification and ideology strongly predict out-group stereotypes, (3) out-group stereotypes strongly predict the perceived risk of out-group violence but are not significantly associated with risk perceptions for other forms of violence and (4) vulnerability factors predict risk perceptions for all forms of violence.
Social Work Scholarship on Forced Migration: A Scoping Review
Authors: Gonzalez Benson Odessa , Wachter Karin , Lee Jessica , Nichols Darlene , Hylton Erica 
Published: June 2020

Abstract
This scoping review identifies and analyses historical to present–day contributions of social work scholarship on forced migration, with the aim of reviewing trends and identifying priority areas for the discipline moving forward. This review examined 331 articles related to forced migration published in 40 social work journals over four decades (1978 to 2019). Findings illustrate notable trends in temporal, methodological, topical and geographical dimensions and how those vary by first authors' locations, research sites and study populations. Temporally, the number of articles has been increasing, quadrupling between 2001–2010 and 2011–2019, with 20 social work journals doubling their number of articles. Methodologically, the large majority of articles were qualitative and/or conceptual. Topically, the most common were practice, intervention, health and mental health, while the least common topics included human rights, social justice, poverty, religion, violence, history and theory. Geographically, social work scholarship was mainly focused on refugees in the Global North and third-country resettlement contexts, and authored by scholars in the Global North. Findings thus reveal critical gaps in topics and geographical biases, raising questions related to issues of ethics, power and the production of knowledge about forced migration in the social work academy.
