Adversity, Uncertainty and Elevated Symptoms of Obsessive Compulsive Disorder: A New Understanding through Resiliency and Positive Psychotherapy
Authors: Güney Sevgi
Published: June 2021

The content of thought, which emerges from the processing of information from the social context lived, is a critical factor that guides whether the behavior is psychopathological or not. In cases where worry, anxiety and fear are dominant in the content of thought, the individual may find himself in some psychopathological processes. Adversity and uncertainty are the main factors that lead to the experience of worry, anxiety and fear which is the last point of these. Uncertainty of information from the social context lived, when matched with adversity, may lead to chaotic situations at the cognitive level, e.g., thought contents such as distortions in thought, severe anxiety and fear. Obsessive compulsive disorder derives from severe worry and anxiety. Although the disorder is classified under anxiety disorders, it is actually a thought distortion disorder. The individual finds himself repeating the strange behavior patterns accompanied by strange thought contents in order to get rid of the severe anxiety and accelerated thought cycle he is exposed to. Ambiguity and uncertainty also may lead to the accelerated thought cycle, ruminations, severe thought distortions, over-generalizations. Ruminations, especially, impair the individual’s ability to think and process emotions gradually. Obsessive Compulsive Disorder will be discussed in terms of ambiguity and uncertainty with the combination of adversity. Positive Psychotherapy, which is one of the latest effective technique in recovery processes of the diseases, will be mentioned.

Moreover, we consider different enable technologies that facilitate computing paradigm evolution. In this context, we focus mainly on fog computing considering its related fundamental issues and recent advances. Besides, we present further research directions toward the sixth generation fog computing paradigm.
Discerning the Strategies for Exiting Your Business
Authors: M. Shepard Jeffrey
Published: June 2021

For many business owners, strategies for operations are well thought out, whereas strategies for exit are not. Exiting a business does not need to occur due to a challenge or disaster. It is possible to plan and exit for the purposes of business growth, retirement, mergers and more. An exit affects the business owner, as it means that they are no longer involved in running or operations of the organization. The aim of this chapter is to identify common exit strategies and understand how they are of benefit to both the business owner or manager and the individual taking over the business. Secondary qualitative research is the research method used, with analysis of strategies and structures used across countries. These findings include differentiation between exit strategies with an understanding of their impact or influence on the business. These include the process of creating and exit strategy and the benefits for having one in place. The expectations of the investor and how they are to be paid back are taken into consideration. The chapter concludes with a solution for any business owner, including how to work with a qualified team to create a logical, well thought out exit plan.
Training the Conductor of the Brainwave Symphony: In Search of a Common Mechanism of Action for All Methods of Neurofeedback
Authors: A. Markovics Jen
Published: June 2021

There are several different methods of neurofeedback, most of which presume an operant conditioning model whereby the subject learns to control their brain activity in particular regions of the brain and/or at particular brainwave frequencies based on reinforcement. One method, however, called infra-low frequency [ILF] neurofeedback cannot be explained through this paradigm, yet it has profound effects on brain function. Like a conductor of a symphony, recent evidence demonstrates that the primary ILF (typically between 0.01–0.1 Hz), which correlates with the fluctuation of oxygenated and deoxygenated blood in the brain, regulates all of the classic brainwave bands (i.e. alpha, theta, delta, beta, gamma). The success of ILF neurofeedback suggests that all forms of neurofeedback may work through a similar mechanism that does not fit the operant conditioning paradigm. This chapter focuses on the possible mechanisms of action for ILF neurofeedback, which may be generalized, based on current evidence.
Low Temperature Characterization and Modeling of FDSOI Transistors for Cryo CMOS Applications
Authors: Cassé Mikaël , Ghibaudo Gérard
Published: June 2021

The wide range of cryogenic applications, such as spatial, high performance computing or high-energy physics, has boosted the investigation of CMOS technology performance down to cryogenic temperatures. In particular, the readout electronics of quantum computers operating at low temperature requires larger bandwidth than spatial applications, so that advanced CMOS node has to be considered. FDSOI technology appears as a valuable solution for co-integration between qubits and consistent engineering of control and read-out. However, there is still lack of reports on literature concerning advanced CMOS nodes behavior at deep cryogenic operation, from devices electrostatics to mismatch and self-heating, all requested for the development of robust design tools. For these reasons, this chapter presents a review of electrical characterization and modeling results recently obtained on ultra-thin film FDSOI MOSFETs down to 4.2 K.
Current Therapeutic Approaches for Osteosarcoma
Authors: Öztürk Recep
Published: June 2021

Osteosarcoma is classically defined as a high-grade spindle-shaped neoplasm with malignant cells that produce osteoid. It is the most common primary malignant bone tumor in children and young adults. It is <1% of all cancers diagnosed, approximately 3.4% of all childhood cancers. The age-adjusted incidence of osteosarcoma is bimodal, with an initial peak in adolescence and then a second peak in patients over 60 years of age. Osteosarcoma is divided into two main groups. In most of the osteosarcomas, the etiological agent cannot be determined and it is called primary osteosarcoma. Osteosarcoma, which develops due to etiologies such as Paget’s disease, radiotherapy or osteonecrosis, is called seconder osteosarcoma. Osteosarcomas are most commonly located in the appendicular skeleton. The most common settlement here is the knee circumference. The distal femur and proximal tibia are the most common locations in the knee. A multidisciplinary approach is indicated in the management of osteosarcoma. The treatment is multimodal, including systemic chemotherapy and local therapy. In this section, we will outline the current standard of care for the systemic and surgical approach to osteosarcoma treatment, as well as an overview of current studies.
Bacterial Resistance in Urinary Tract Infections: Multidrug Resistant ESBL Producing Gram Negative Uropathogens from Patients
Authors: Bonsu Karikari Akosua , Kosi Setsoafia Saba Courage , Yembilla Yamik David
Published: June 2021

Urinary tract infection is one of the most common bacterial infectious diseases encountered in clinical practice. The development and spread of multidrug resistant isolates are of great global health burden; among them, extended spectrum beta-lactamase (ESBL) producing Enterobacteriaceae has been a prime concern. This topic describes the resistance patterns of eighty three (83) Gram negative uropathogens to different classes of antibiotics. Bacteria isolates were obtained from patients of all age groups who sought medical attention at a secondary and tertiary hospital in Northern Ghana. Culture and isolation methods employed were the quantitative urine culture on Cysteine Lysine Electrolyte Deficient (CLED) agar and standard biochemical tests. ESBL production was detected using the CLSI recommended phenotypic confirmatory test along with routine antibiotic susceptibility test, adopting the Kirby-Bauer disk diffusion method. Out of 83 isolates, seven (7) Gram negative uropathogens were characterized and ESBLs were detected in 32 of the isolates. Escherichia coli was the pathogen with most ESBL positive strains. Generally high and multiple drug resistance were recorded in both ESBL and non-ESBL strains to the empirical drugs, however, ESBL positive strains significantly (p = 0.000) showed greater resistance. A notable finding was the appreciable resistance exhibited by ESBL strains to last line treatment drugs that include aminoglycosides and imipenem.
Siega Verde and the open-air rock art of the northern Iberian Peninsula (Spain)
Authors: BALBÍN-BEHRMANN Rodrigo De , ALCOLEA-GONZÁLEZ Jose Javier
Published: June 2021

Siega Verde was the third open-air rock art site to be discovered in the Iberian Peninsula, even before Côa and the controversy that followed that discovery. Its practicable size and the study carried out without any publicity allowed the analysis of a new reality that would change the interpretation of Palaeolithic art. From the start of the research, stylistic criteria were used to date the art in the absence of archaeological excavations. Although this has often been criticized, it meant that Siega Verde and Côa could be dated from Leroi-Gourhan’s Style II onwards. Excavations at Fariseu, a site belonging to Côa in Portugal, have proved that hypothesis archaeologically, as well as supporting the applicability of Leroi-Gourhan’s styles. Siega Verde is a good representative of Palaeolithic art in the open, on rocks by a river-bank or on prominent hills, but it is not the only form that can be catalogued as open-air rock art, because there are intermediate forms. These are found in cave entrances and in rock-shelters all over the Iberian Peninsula, especially in areas where little evidence of Palaeolithic art used to be known, such as on the southern Mediterranean coast and in Andalusia. This site possesses an exterior Upper Palaeolithic art ensemble, similar to the art found inside caves and of the same age, but in a different location. Formal relationships are usual inside and outside the caves and in both cases they represent a communicative code that did not need the dark and mystery to be expressed.
Outlandish names on the provincial doors: German Jews in Victorian Bradford and their expression of identities
Authors: morawska Lucia
Published: June 2021

This paper seeks to integrate the study of the German Jewish minority in the Victorian north of England, Yorkshire in particular, within the wider context of Victorian history and Jewish and migration studies. Its aim is to contribute to English-Jewish social and cultural history by uncovering the complex relationship between German Jewish and Victorian communities in the provinces and how these affected national and religious identity formation in the modern period. The essay analyses international political and social engagements of German Jews in Bradford and the impact of those engagements on their identity. It selectively looks at two prominent German Jewish figures: Jacob Behrens (1806–1889) and Jacob Moser (1839–1922).
A Comparison of a RANS Based VPP to on the Water Sailing Performance
Authors: Doyle Tyler , Knight Bradford , Swain Duncan
Published: June 2021

This paper compares performance predictions from a Reynolds Averaged Navier Stokes (RANS) based Velocity Prediction Program (VPP) to on the water testing of a J70. The J70 has been outfitted with a system to determine sail flying shapes, apparent wind conditions and performance data. The on the water testing is conducted in both racing and controlled sailing conditions. Data taken during racing conditions is analyzed to determine optimal performance envelopes while data taken in controlled conditions is used to match exact sailing and VPP states. The data acquisition system combines a number of standard marine sensors including a sonic anemometer, a GPS, a digital compass, an accelerometer and a gyroscope with custom sensors that measure rudder and boom angles as well as a custom sail shape acquisition system. The RANS based VPP developed by Doyle CFD has three main components; an aerodynamic force model, a hydrodynamic force model and an algorithm to balance the forces. The force balance routine uses four degrees of freedom; boat speed, yaw, heel and rudder angle to balance the aerodynamic and hydrodynamic forces for a given true wind speed and angle. The force models are derived from RANS CFD data calculated using OpenFOAM. The aerodynamic forces are calculated using steady state RANS as a function of apparent wind angle, apparent wind speed and sail flying shape. The VPP force model is derived by fitting response surfaces to this data. The aerodynamic CFD is run with sail flying shapes recorded from on the water testing. Using accurate flying shapes is critical for picking out slight aerodynamic differences in sail and rig setup. The hydrodynamic CFD data points are calculated using RANS Volume of Fluid CFD (VOF) as a function of boat speed, rudder angle, yaw angle, heel angle and displacement. Response surfaces are generated from a 64 data point array of RANS VOF simulations.
Modal Analysis of Pressures on a Full Scale Spinnaker
Authors: Deparday Julien , Bot Patrick , Hauville Fréderic , Augier Benoit , Rabaud Marc , Motta Dario , Le Pelley David
Published: June 2021

While sailing offwind, the trimmer typically adjusts the downwind sail "on the verge of luffing", letting occasionally the luff of the sail flapping. Due to the unsteadiness of the spinnaker itself, maintaining the luff on the verge of luffing needs continual adjustments. The propulsive force generated by the offwind sail depends on this trimming and is highly fluctuating. During a flapping sequence, the aerodynamic load can fluctuate by 50% of the average load. On a J/80 class yacht, we simultaneously measured time resolved pressures on the spinnaker, aerodynamic loads, boat and wind data. Significant spatio-temporal patterns are detected in the pressure distribution. In this paper we present averages and main fluctuations of pressure distributions and of load coefficients for different apparent wind angles as well as a refined analysis of pressure fluctuations, using the Proper Orthogonal Decomposition (POD) method. POD shows that pressure fluctuations due to luffing of the spinnaker can be well represented by only one proper mode related to a unique spatial pressure pattern and a dynamic behavior evolving with the Apparent Wind Angles. The time evolution of this proper mode is highly correlated with load fluctuations. Moreover, POD can be employed to filter the measured pressures more efficiently than basic filters. The reconstruction using the first few modes allows to restrict to the most energetic part of the signal and remove insignificant variations and noises. This might be helpful for comparison with other measurements and numerical simulations.
Towards a New Mathematical Model for Investigating Course Stability and Maneuvering Motions of Sailing Yachts
Authors: Angelou Manolis , Spyrou Kostas J.
Published: June 2021

In order to create capability for analyzing course instabilities of sailing yachts in waves, the authors are at an advanced stage of development of a mathematical model comprised of two major components: an aerodynamic, focused on the calculation of the forces on the sails, taking into account the variation of their shape under wind flow; and a hydrodynamic one, handling the motion of the hull with its appendages in water.

Regarding the first part, sails provide the aerodynamic force necessary for propulsion. But being very thin, they have their shape adapted according to the locally developing pressures. Thus, the flying shape of a sail in real sailing conditions differs from its design shape and it is basically unknown. The authors have tackled the fluid-structure interaction problem of the sails using a 3d approach where the aerodynamic component of the model involves the application of the steady form of the Lifting Surface Theory, in order to obtain the force and moment coefficients, while the deformed shape of each sail is obtained using a relatively simple Shell Finite Element formulation. The hydrodynamic part consists of modeling hull reaction, hydrostatic and wave forces.

A Potential Flow Boundary Element Method is used to calculate the Side Forces and Added Mass of the hull and its appendages. The Side Forces are then incorporated into an approximation method to calculate Hull Reaction terms. The calculation of resistance is performed using a formulation available in the literature. The wave excitation is limited to the calculation of Froude - Krylov forces.
Advanced CFD Simulations of free-surface flows around modern sailing yachts using a newly developed openFOAM solver
Authors: Meyer Janek , Renzsch Hannes , Graf Kai , Slawig Thomas
Published: June 2021

While plain vanilla OpenFOAM has strong capabilities with regards to quite a few typical CFD-tasks, some problems actually require additional bespoke solvers and numerics for efficient computation of high-quality results. One of the fields requiring these additions is the computation of large-scale free-surface flows as found e.g. in naval architecture. This holds especially for the flow around typical modern yacht hulls, often planing, sometimes with surface-piercing appendages. Particular challenges include, but are not limited to, breaking waves, sharpness of interface, numerical ventilation (aka streaking) and a wide range of flow phenomenon scales. A new OF-based application including newly implemented discretization schemes, gradient computation and rigid body motion computation is described. In the following the new code will be validated against published experimental data; the effect on accuracy, computational time and solver stability will be shown by comparison to standard OF-solvers (interFoam / interDyMFoam) and Star CCM+. The code’s capabilities to simulate complex “real-world” flows are shown on a well-known racing yacht design.
The role of dominant personality traits in multiple perpetrator rape proclivity
Authors: Petrella Alessia A. , Harkins Leigh
Published: June 2021

Background/Aim

Multiple perpetrator sexual assaults (MPSA) often involve more severe forms of sexual violation and result in a host of impairments for the victim. To further investigate the characteristics of MPSA, researchers have taken an interest in personality traits, varying group dynamics, and the role a leader may play. This study examines the possible linkage between dominant personality characteristics and the propensity to engage in multiple perpetrator sexual assault.

Method

Using anonymous online surveys, university student participants were assessed on The Personality Scale for Dominance and the Multiple Perpetrator Rape Proclivity Scale (M-PRIS). We hypothesized that dominant personality traits would predict M-PRIS proclivity score.

Results

Of 176 respondents, 84 heterosexual males completed both measures. Dominance scores did not significantly predict total M-PRIS score, F(1,82) = 1.1, p = .296, the Enjoyment subscale score, F(1,82) = .66, p = .420, the Likelihood subscale score, F(1,86) = 1.13, p = .292, or the Arousal subscale score, F(1,82) = 0.66, p = .419.

Conclusion

In this study, dominance was not associated with a proclivity for multiple perpetrator sexual violence. Other important factors, such as psychopathy or deviant sexual interests, may mediate the relationship between dominant personality traits and the tendency to initiate a multiple perpetrator sexual assault. Future studies should examine alternative relationships in hopes of gaining a clearer picture of individuals who exhibit a proclivity for sexual violence with the aim to inform prevention and practice.

Research suggests that the news media plays an important role in shaping public opinion about sex crimes and the people who commit them, thereby influencing the development of laws and policies. The media has potential to fuel non-evidence-based policies that are ineffective and counterproductive. Alternatively, the media offers a powerful vehicle for educating the public and promoting evidence-based practices and policies. The current study aimed to examine newspaper reports of sexual crimes across four countries with different criminal justice responses to sexual offending. Constructed week sampling was used to generate samples of newspaper articles over a six-month period in 2015. Episodic articles were coded to examine how people accused/charged with sexual offenses were portrayed, the extent to which articles aligned with stereotypes, and the extent to which rehabilitation was mentioned as a solution (n = 240). Episodic and thematic articles were combined to code for systemic/environmental solutions to sexual crimes (n = 290). Overall, Norwegian articles demonstrated more neutral and less informative portrayals of individuals who have sexually offended, compared to US, UK, and New Zealand. At the same time, Norwegian articles were less likely to discuss solutions to sexual offending. Rehabilitation was rarely discussed as a solution. However, environmental/systemic solutions were discussed in approximately one third of articles. Implications for framing sexual abuse as a public health problem rather than a criminal justice problem are discussed.
The Newcomer’s Guide to Edmonton and Community Translation: Materially and Culturally Situated Practices
Authors: Cisneros Odile , De Léon Ann
Published: June 2021

In line with the current turn towards the study of material culture in Translation Studies, this paper explores community translation in Edmonton through the case study of the Newcomer’s Guide to Edmonton (NGE). A 63-page handbook of essential information for new residents published by the City of Edmonton (2016), the NGE was translated into 7 languages in a project that employed community translators. This research examines community translation as both a materially and a culturally situated practice. We discuss how the materialities of communication and translation (Littau, 2016) can be addressed through this case study on community translation (Taibi and Ozolins, 2016). We also look at the process of community translation, specifically, the material conditions under which community translators work, often as volunteers with limited training who serve newcomers. We explore the case of the translation of the NGE as a culturally situated practice where community translators faced the particularities not only of the material translated, but also of the local context and target communities. Our research suggests that the process of the NGE’s translation not only empowered translators to make appropriate choices for their local communities, but also developed strategies for elevating the quality of the final product.

THE ROLE OF MULTINATIONAL CORPORATIONS IN THE MAIN CONCEPT OF GREEN PRODUSTION IN THE CEMENT INDUSTRY
Authors: Petrović-Ranđelović Marija
Published: June 2021

The concept of corporate environmental responsibility is under-implemented in developing countries, especially in those where there is insufficient application of environmental legislation regulating the way in which the business activities of the participants are carried out. In the face of insufficient government support, many multinational corporations, in collaboration with the World Business Council for Sustainable Development, have initiated collective action to adopt best environmental practices in their industries to better protect the environment. It is about adopting green programs, and this is characteristic of corporations in the cement industry, which face many challenges such as: lack of raw materials, depletion of fossil fuel reserves, increased demand for cement and concrete, strong environmental concerns related to climate change. Several different forms of voluntary initiatives can be identified by which multinational corporations seek to achieve more favourable position on the global market, such as: unilateral initiatives initiated by enterprises in the absence of government support, adoption of environmental standards on a voluntary basis have been prescribed by the state, and partnership agreements resulting from the cooperation of public and private actors. This paper reviews individual multinational corporations from the African state of Morocco and how they adopt best environmental practices from other corporations in the cement industry. Adopted environmental practices can increase the capacity of these corporations in the field of environmental protection, and provide them with communication skills that will enhance collaboration and exchange of ideas with other corporations.

Authors: Mitrović Goran , Starčević Vitomir
Published: June 2021

Globalization, in its current form, represents a new dynamic complex, especially when it comes to its implications for the economy and business of economic entities. It manifests its implications not only through competition, but also through economic growth and development. A modern company should provide adequate management that is able to create and develop comparative advantages that will enable it to be actively involved in global market flows. Global changes have conditioned a new way of doing business, and thus a significant turn in the approach to financial management. This has led to changes in the basic economic settings and criteria for successful management and business. The financial position of a company is one of the indicators of the company's success to function in a global and turbulent market environment. Starting from this fact, a practical treatment of this problem and analytical indicators of the financial position of the three dependent production companies operating within the MH Elektroprivreda Republike Srpske will be done. The aim of the research is to show the extent to which the management of these companies has accepted the requirements of global economic processes and adapted their business to them. That is, whether financial management provides a satisfactory level of liquidity and financial stability of these three companies.
Video transaction algorithm considering FISCO alliance chain and improved trusted computing
Authors: Yang Yang , Yu Dingguo , Yang Chen
Published: June 2021

With the advent of the era of self media, the demand for video trading is becoming more and more obvious. Alliance blockchain has the characteristics of traceable transaction records, tamper proof transaction records, decentralized transactions and faster transaction speed than public chains. These features make it a trading platform. Trusted computing can solve the problem of non Byzantine attack in the aspect of hardware. This paper proposes a video transaction algorithm considering FISCO alliance chain and improved trusted computing. First, an improved trusted computing algorithm is used to prepare a trusted transaction environment. Second, the video summary information extraction algorithm is used to extract the summary information that can uniquely identify the video. Finally, based on the video transactions algorithm of FISCO alliance chain, the video summary information is traded on the chain. Experimental results show that the proposed algorithm is efficient and robust for video transactions. At the same time, the algorithm has low computational power requirements and algorithm complexity, which can provide technical support for provincial and county financial media centers and relevant media departments.

Kidney Transplantation and Cardiovascular Events Among Patients With End‐Stage Renal Disease Due to Lupus Nephritis: A Nationwide Cohort Study
Authors: Jorge April , Fu Xiaoqing , Cook Claire , Lu Na , Zhang Yuqing , Choi Hyon K. , Wallace Zachary S.
Published: June 2021

Objective

To assess the potential impact of kidney transplantation on cardiovascular (CV) events among patients with end‐stage renal disease (ESRD) due to lupus nephritis (LN).

Methods

In a nationwide cohort study, we identified all patients with LN‐ESRD enrolled in the US Renal Data System who were waitlisted for a kidney transplant and enrolled in Medicare between January, 2000 and December, 2016. The primary outcome was incident CV events, including myocardial infarction (MI) and ischemic cerebrovascular accident (CVA). We used time‐dependent Cox regression to estimate the hazard ratios (HRs) of these outcomes associated with kidney transplant as a time‐varying exposure, adjusting for sex, age, race, ethnicity, geographic region, year of ESRD onset, first ESRD treatment modality (e.g., hemodialysis or peritoneal dialysis), Charlson Comorbidity Index score, and history of prior organ transplants.

Results

Of 5,963 waitlisted patients with LN‐ESRD, 3,209 (54%) had a kidney transplant during the study period. The majority were female (82%), and African American patients represented 48% of waitlisted patients and 43% of transplanted patients. Kidney transplantation was associated with a lower risk of incident CV events (adjusted HR 0.31 [95% confidence interval (95% CI) 0.18–0.53]) as well as lower risks of MI and CVA (adjusted HRs 0.13 [95% CI 0.08–0.34] and 0.30 [95% CI 0.16–0.54], respectively).

Conclusion

Kidney transplantation was associated with a reduced risk of CV events, including MI and CVA, in patients with LN‐ESRD. Our findings highlight the importance of identifying barriers to transplantation in this population, as improved access could reduce CV morbidity.

Objective

To examine associations between changes in rheumatoid arthritis (RA) symptoms and depressive symptoms adjusted for other time‐varying characteristics, and to test if these associations differed by education, race/ethnicity, or gender.

Methods

Data from the 1988–1998 US National Rheumatoid Arthritis Study were analyzed (n = 854). Time‐varying covariates included year of the study, pain, functional ability, household work disability, parental status, marital status, employment status, and social support. The time‐invariant covariates included years since diagnosis, education, race/ethnicity, and gender. Multivariate multilevel‐model analyses were used to estimate associations within people over time.

Results

Patients with RA experience considerable change in depressive symptoms, pain, functional disability, and household work disability over the study period. Depressive symptoms were driven more by differences between people compared to changes within people over time. Findings show that patients experienced increases in depressive symptoms over the study period. The rate of change in depressive symptoms did not differ by education, race/ethnicity, or gender. Times of worse pain, functional disability, and household disability were associated with worse depressive symptoms. The association of functional disability and depressive symptoms was stronger for men than women.

Conclusion

Increases in pain and disability were associated with worse depressive symptoms, adjusted for covariates. It is important to monitor and treat both mental and physical health symptoms. Future research efforts should focus on collecting data reflecting the educational, gender, and racial/ethnic diversity of individuals with RA.

Objective

Patients with inflammatory arthritis have a high risk of sleep disturbances and disorders. The objective was to evaluate the evidence of nonpharmacologic interventions targeting sleep disturbances or disorders in patients with inflammatory arthritis.

Methods

A systematic search was undertaken from inception to September 8, 2020. We included randomized trials concerning nonpharmacologic interventions applied in adults with inflammatory arthritis and concomitant sleep disturbances or disorders. The primary outcome was the sleep domain, while secondary outcomes were core outcome domains for inflammatory arthritis trials and harms. The Cochrane Risk of Bias tool was applied, and the overall quality of the evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation criteria. Effect sizes for continuous outcomes were based on the standardized mean difference, combined using random‐effects meta‐analysis.

Results

Six trials (308 patients) were included in the quantitative synthesis; 3 of these reported improvement in sleep in favor of the nonpharmacologic interventions. The meta‐analysis of the sleep domains indicated a large clinical effect of –0.80 (95% confidence interval –1.33, –0.28) in favor of nonpharmacologic interventions targeting sleep disturbances or disorders. The estimate was rated down twice for risk of bias and unexplained inconsistency; this risk was assessed as corresponding to low‐quality evidence. None of the secondary core outcomes used in contemporary inflammatory arthritis trials indicated a clinical benefit in favor of nonpharmacologic interventions targeting sleep.

Conclusion

Nonpharmacologic interventions targeting sleep disturbances/disorders in patients with inflammatory arthritis indicated a promising effect on sleep outcomes, but not yet with convincing evidence.

Highly efficient electrocatalysts composed of earth‐abundant elements are desired for water‐splitting to produce clean and renewable chemical fuel. Herein, a heteroatomic‐doped multi‐phase Mo‐doped nickel phosphide/nickel sulfide (Mo‐NiPx/NiSy) nanowire electrocatalyst is designed by a successive phosphorization and sulfuration method for boosting overall water splitting (both oxygen and hydrogen evolution reactions (HER)) in alkaline solution. As expected, the Mo‐NiPx/NiSy electrode possesses low overpotentials both at low and high current densities in HER, while the Mo‐NiPx/NiSy heterostructure exhibits high active performance with ultra‐low overpotentials of 137, 182, and 250 mV at the current density of 10, 100, and 400 mA cm−2 in 1 m KOH solution, respectively, in oxygen evolution reaction. In particular, the as‐prepared Mo‐NiPx/NiSy electrodes exhibit remarkable full water splitting performance at both low and high current densities of 10, 100, and 400 mA cm−2 with 1.42, 1.70, and 2.36 V, respectively, which is comparable to commercial electrolysis.

Neuromorphic computing, which merges learning and memory functions, is a new computing paradigm surpassing traditional von Neumann architecture. Apart from the plasticity of artificial synapses, the simulation of neurons’ multi‐input signal integration is also of great significance to realize efficient neuromorphic computing. Since the structure of transistors and neurons is strikingly similar, capacitively coupled multi‐terminal pectin‐gated oxide electric double layer transistors are proposed here as artificial neurons for classification. In this work, the free logic switching of “AND” and “OR” is realized in the device with triple in‐plane gates. More importantly, the linear classification function on a single neuron transistor is demonstrated experimentally for the first time. All the results obtained in this work indicate that the prepared artificial neuron can improve the efficiency of artificial neural networks and thus will play an important role in neuromorphic computing.

Published: June 2021

Donor–acceptor type polymers and supramolecules are promising electrets in photonic field‐effect transistor (FET)‐type memory because of their diversified polymer‐structure design and favorable mechanical tolerance. Using intermolecular association, supramolecule electrets can surpass donor–acceptor type polymers with versatile facile combining processes. Currently, there has been no application of charge‐transfer (CT) supramolecules in electrets of photonic FET memory devices. Herein, a novel series of CT‐based supramolecular electrets comprising poly(1‐pyrenemethyl methacrylate) (PPyMA) and 7,7,8,8‐tetracyanoquinodimethane (TCNQ) is used to elucidate the effect of CT on photonic FET memory. Accordingly, memory devices based on the supramolecular electret with an equimolar content of pyrene and TCNQ exhibit superior bistable memory switchability using electrical/photoprograming with UV (365 nm) and green light (525 nm). This shows a broad memory window of 34 V and favorable memory ratio of over 106 after 104 s. The memory performance can be attributed to the favorable molecular association and dispersion between pyrene and TCNQ in the solid state. The results provide evidence that CT‐based supramolecular electrets warrant applications in optoelectronic applications.

Published: June 2021

Bi2S3‐based thermoelectric materials without toxic and expensive elements have a high Seebeck coefficient and intrinsic low thermal conductivity. However, Bi2S3 suffers from low electrical conductivity, which makes it a less‐than‐perfect thermoelectric material. In this work, halogen elements F, Cl, and Br from halogen acid are successfully introduced into the Bi2S3 lattice using a hydrothermal procedure to efficiently improve the carrier concentration. Compared with the pure sample, the electron concentration of the Bi2S3 sample treated with HCl is increased by two orders of magnitude. An optimal power factor of 470 µW m−1 K−2 for the Bi2S2.96Cl0.04 sample at 673 K is obtained. Density functional theory calculations reveal that an effective delocalized electron conductive network forms after Cl doping, which raises the Fermi level into the conduction bands, thus generating more free electrons and improving the conductivity of the Bi2S3‐based materials. Ultimately, an excellent ZT of ≈0.8 is achieved at 673 K for the Bi2S2.96Cl0.04 sample, which is one of the highest values reported for a state‐of‐the‐art Bi2S3 system. The energy conversion efficiency of the module reaches 2.3% at 673 K with a temperature difference of 373 K. This study offers a new method for enhancing the thermoelectric properties of Bi2S3 by adding halogen acid in the hydrothermal process for powder synthesis.

The anode materials for sodium‐ion batteries (SIBs) such as soft carbon, hard carbon, or alloys suffer from low specific capacity, poor rate capability, and high cost. Various transition metal oxides materials possess high specific capacity and suitable working potential, however, huge volume change and unstable electrode/electrolyte interfaces limit their practical applications. Herein, an ultrathin carbon‐coated iron‐based borate, (Fe3BO5), as an anode material for SIBs is reported. The carbon coated Fe3BO5 composite as an anode material possesses a reversible specific capacity of 548 mAh g−1 with a high initial coulombic efficiency of 72.6% at a current density of 50 mA g−1, and maintains a capacity retention ratio of 99% after 1000 cycles at 2000 mA g−1. Moreover, this anode can work well over a wide temperature range (‐40–60 °C). Furthermore, a sodium‐ion full cell using this anode coupling with iron‐based cathode (Na3Fe2(PO4)2(P2O7)@rGO) cathode is fabricated, which exhibits a wide operating temperature range from −40 to 60 °C with a maximum energy density of 175 Wh Kg−1 and a maximum power density of 1680 W Kg−1. Most importantly, this full‐cell configuration is low‐cost due to its inexpensive iron based raw material for both anode and cathode.
