ObjectiveTo investigate the abundance and the prevalence of Dysosmobacter welbionis J115T, a novel butyrate-producing bacterium isolated from the human gut both in the general population and in subjects with metabolic syndrome. To study the impact of this bacterium on host metabolism using diet-induced obese and diabetic mice.DesignWe analysed the presence and abundance of the bacterium in 11 984 subjects using four human cohorts (ie, Human Microbiome Project, American Gut Project, Flemish Gut Flora Project and Microbes4U). Then, we tested the effects of daily oral gavages with live D. welbionis J115T on metabolism and several hallmarks of obesity, diabetes, inflammation and lipid metabolism in obese/diabetic mice.ResultsThis newly identified bacterium was detected in 62.7%–69.8% of the healthy population. Strikingly, in obese humans with a metabolic syndrome, the abundance of Dysosmobacter genus correlates negatively with body mass index, fasting glucose and glycated haemoglobin. In mice, supplementation with live D. welbionis J115T, but not with the pasteurised bacteria, partially counteracted diet-induced obesity development, fat mass gain, insulin resistance and white adipose tissue hypertrophy and inflammation. In addition, live D. welbionis J115T administration protected the mice from brown adipose tissue inflammation in association with increased mitochondria number and non-shivering thermogenesis. These effects occurred with minor impact on the mouse intestinal microbiota composition.ConclusionsThese results suggest that D. welbionis J115T directly and beneficially influences host metabolism and is a strong candidate for the development of next-generation beneficial bacteria targeting obesity and associated metabolic diseases.

Published: June 2021

ObjectivesThis meta-analysis aims to (1) evaluate the efficacy of physical activity interventions in heart failure and (2) to identify intervention characteristics significantly associated with the interventions’ efficacy.MethodsRandomised controlled trials reporting intervention effects on physical activity in heart failure were combined in a meta-analysis using a random-effect model. Exploratory meta-analysis was performed by specifying the general approach (eg, cardiac rehabilitation), strategies used (eg, action planning), setting (eg, centre based), mode of delivery (eg, face to face or online), facilitator (eg, nurse), contact time and behavioural change theory use as predictors in the random-effect model.ResultsInterventions (n=21) had a significant overall effect (SMD=0.54, 95% CI (0.13 to 0.95), p<0.0005). Combining an exercise programme with behavioural change intervention was found efficacious (SMD=1.26, 95% CI (0.26 to 2.26), p<0.05). Centre-based (SMD=0.98, 95% CI (0.35 to 1.62), and group-based (SMD=0.89, 95% CI (0.29 to 1.50),) delivery by a physiotherapist (SMD=0.84, 95% CI (0.03 to 1.65),) were significantly associated with efficacy. The following strategies were identified efficacious: prompts/cues (SMD=3.29, 95% CI (1.97 to 4.62)), credible source (standardised mean difference, SMD=2.08, 95% CI (0.95;3.22)), adding objects to the environment (SMD=1.47, 95% CI (0.41 to 2.53)), generalisation of the target behaviour SMD=1.32, 95% CI (0.22 to 2.41)), monitoring of behaviour by others without feedback (SMD=1.02, 95% CI (0.05 to 1.98)), self-monitoring of outcome(s) of behaviour (SMD=0.79, 95% CI (0.06 to 1.52), graded tasks (SMD=0.73, 95% CI (0.22 to 1.24)), behavioural practice/rehearsal (SMD=0.72, 95% CI (0.26 to 1.18)), action planning (SMD=0.62, 95% CI (0.03 to 1.21)) and goal setting (behaviour) (SMD=0.56, 95% CI (0.03 to 1.08)).ConclusionThe meta-analysis suggests intervention characteristics that may be suitable for promoting physical activity in heart failure. There is moderate evidence in support of an exercise programme combined with a behavioural change intervention delivered by a physiotherapist in a group-based and centre-based settings.PROSPERO registerationCRD42015015280.
Rotating behind Privacy: An Improved Lightweight Authentication Scheme for Cloud-based IoT Environment
Authors: Chaudhry Shehzad Ashraf , Irshad Azeem , Yahya Khalid , Kumar Neeraj , Alazab Mamoun , Zikria Yousaf Bin 
Published: June 2021

The advancements in the internet of things (IoT) require specialized security protocols to provide unbreakable security along with computation and communication efficiencies. Moreover, user privacy and anonymity has emerged as an integral part, along with other security requirements. Unfortunately, many recent authentication schemes to secure IoT-based systems were either proved as vulnerable to different attacks or prey of inefficiencies. Some of these schemes suffer from a faulty design that happened mainly owing to undue emphasis on privacy and anonymity alongside performance efficiency. This article aims to show the design faults by analyzing a very recent hash functions-based authentication scheme for cloud-based IoT systems with misunderstood privacy cum efficiency tradeoff owing to an unadorned design flaw, which is also present in many other such schemes. Precisely, it is proved in this article that the scheme of Wazid et al. cannot provide mutual authentication and key agreement between a user and a sensor node when there exists more than one registered user. We then proposed an improved scheme and proved its security through formal and informal methods. The proposed scheme completes the authentication cycle with a minor increase in computation cost but provides all security goals along with privacy.

Logic and the Movement of Reasoning: Pierre Gassendi on the Three Acts of the Mind
Authors: Corneanu Sorana 
Published: June 2021

AbstractThe aim of this paper is to assess the central role the imagination acquires in Pierre Gassendi’s logic. I trace the structuring scheme of the three acts of the mind—common to a good number of late scholastic and early modern logics—to the Thomistic notion of the movement of reasoning in knowledge and argue that Gassendi revisits this notion in his logic. The three acts scheme is from the beginning a bridge between logic and the natural philosophical treatment of the soul. I show how Gassendi’s take on the three acts is similarly poised between his Logic and his Physics and I discuss the rationale, sources and consequences of his attribution of the three acts to the imagination. I argue for the following points: Gassendi’s conception of the logical role of the imagination answers to his empiricist epistemology, his naturalized view of the mind (which involves a defense of thinking in animals) and his notion of a natural logic; it is also operative in his pairing of the formal mechanism of logical operations with a progressive mechanism of the operations of the mind; and it serves as a counterpart to his experimental understanding of the progress of knowledge.1
The Ontogeny of Kinship Categorization
Authors: Mitchell Alice , Jordan Fiona M. 
Published: June 2021

Abstract
Human kinship systems play a central role in social organization, as anthropologists have long demonstrated. Much less is known about how cultural schemas of relatedness are transmitted across generations. How do children learn kinship concepts? To what extent is learning affected by known cross-cultural variation in how humans classify kin? This review draws on research in developmental psychology, linguistics, and anthropology to present our current understanding of the social and cognitive foundations of kinship categorization. Amid growing interest in kinship in the cognitive sciences, the paper aims to stimulate new research on the ontogeny of kinship categorization, a rich domain for studying the nexus of language, culture, and cognition. We introduce an interdisciplinary research toolkit to help streamline future research in this area.
Secular Values, Economic Development, and Gender Inequality in a Global Context
Authors: Hekmatpour Peyman 
Published: June 2021

Abstract
This article investigates how cultural and material factors can explain disparities observed in different forms of gender inequality between and within nations. Using data from multiple sources, the author constructs a panel dataset that includes 150 country-year observations nested in 70 countries, covering 23 years from 1991 to 2013. Through estimating hybrid panel models, this article discovers that more secular countries have lower maternal mortality ratios, higher female labor force participation rates, greater shares of parliamentary seats held by women, higher rates of women with completed secondary education, and smaller shares of the total population who adhere to inequitable gender attitudes. Moreover, from a longitudinal perspective, secularization is the only predictor of declined maternal mortality ratios and increased female parliamentary representation within a country. Interactive models suggest that further secularization within high-income nations can increase maternal mortality ratios. Furthermore, secularization’s equalizing effect on parliamentary representation moderates as countries become more affluent.
Legislating without Evidence: The Recast of the EU Return Directive
Authors: Majcher Izabella , Strik Tineke 
Published: June 2021

Abstract
The article discusses the recast of the EU Return Directive (2008/115/EC) from the perspective of effectiveness and fundamental rights protection, as two underlying objectives of the Directive. Relying on the implementation assessment of the Directive carried out by the European Parliamentary Research Service, the article analyses the way in which Member States have implemented the Directive and how this has impacted the effectiveness of the Directive. If adopted as proposed, will the recast strengthen or further undermine the effectiveness? The assessment focuses on return decision, voluntary departure, entry ban, and detention. It also looks at omissions in the recast proposal, namely a missed opportunity to remedy the current shortcomings as regards non-returnable people. As the article concludes, the recast proposal will hardly improve the effectiveness of return and may lead to violations of fundamental rights of people in an irregular situation.
Down the Drain with General Principles of EU Law? The EU-Turkey Deal and ‘Pseudo-Authorship’
Authors: Hillary Lynn 
Published: June 2021

Abstract
This article aims to provide guidelines to the courts of the Member States and the CJEU concerning the authorship of external migration management deals, and the judicial review of such deals based on the general principles of EU law.
The selected example of external migration management is the EU-Turkey Deal, which is identified in this article as an example of ‘pseudo-authorship’: the EU is the de facto author of the deal, but the Member States (as pseudo-authors) are regarded by the General Court as the actual authors. The article shows that the pseudo-authorship approach may lead to the circumvention of general principles of EU law.
To avoid further erosion of these principles in the wake of any future deals on migration management, a definite need for a serious investigation of authorship exists. This article recommends assessing authorship with the three scenarios in mind that are identified in this article: the EU as only author; the EU as de facto author and the Member States as pseudo-authors; or the Member States as only authors. All three scenarios, it is argued here, induce judicial review based on the general principles of EU law.
Testing Turkey’s State Capacity: The Syrian Migration Crisis as Catalyst
Authors: Ulusoy Kivanç 
Published: June 2021

Abstract
The exodus of around 5 million people from Syria has evolved into a transnational ‘social question’, requiring a transnational response. The latest Syrian assault on Idlib in February 2020, creating one of the worst humanitarian crises of this brutal civil war, brought this to the world’s attention again. Highlighting the scale of this ‘social question’ on the eve of a Covid-19 pandemic, it shows that displaced Syrians of Idlib had been trapped between the advancing Syrian regime and Russian troops. In response, Turkey, already hosting almost 3.5 million Syrians and closing its border in 2015 to prevent a further influx, let refugees – Syrians and migrants from other countries – head for the EU. Aiming to cajole the EU into heeding its demands, Turkey linked this to its Syria cause. Once again, the latest crisis showed that Turkey had reached the limit of its capacity to absorb more Syrians. This paper deals with Turkey’s response and alternatives for the most relevant stakeholder, the EU.
A “New Lens” on African Military Tradition
Authors: Page Melvin E. 
Published: June 2021

Abstract
Asking the question, “Is there a common African military tradition?” leads to consideration of the all too readily accepted tripartite periodization of African history as precolonial, colonial, and postcolonial. Does such a model sufficiently encompass African agency and actions? Or instead—being keyed to the colonial moment in the African past—might it privilege institutions of a decidedly European character? As an alternative, this essay suggests examining Africa’s military tradition around four alternatively defined analytical touchstones, each built upon exemplars of indigenous African activity. It argues that using such a “new lens” offers an opportunity to consider if there are not a variety of African military traditions, rather than an over-generalized system of supposed military values historically common to all African soldiers.
Synthesis of Vortex Rossby Waves. Part III: Rossby Waveguides, Vortex Motion, and the Analogy with Midlatitude Cyclones
Authors: Gonzalez III Israel , Willoughby H. E. 
Published: June 2021

AbstractVortex Rossby waves (VRWs) affect tropical cyclones’ (TCs’) motion, structure, and intensity. They propagate within annular waveguides defined by a passband between Ω1D, the Doppler-shifted frequency of a one-dimensional VRW, and zero. Wavenumber-1 VRWs cause TC motion directly and have wider waveguides than wavenumbers ≥ 2. VRWs forced with fixed rotation frequency propagate away from the forcing. Initially outward-propagating waves are Doppler shifted to zero at a critical radius, where they are absorbed. Initially inward-propagating waves are Doppler shifted to Ω1D, reflect from a turning point, propagate outward, and are ultimately absorbed at the critical radius. Between the forcing and the turning radii, the VRWs have standing-wave structure; outward from the forcing they are trailing spirals. They carry angular momentum fluxes that act to accelerate the mean flow at the forcing radius and decelerate it at the critical radius. Mean-flow vorticity monopoles are inconsistent with Stokes’s theorem on a spherical Earth, because a contour enclosing the monopole’s antipode would have nonzero circulation but would enclose zero vorticity. The Rossby waveguide paradigm also fits synoptic-scale Rossby waves in a meridionally sheared zonal flow. These waves propagate within a waveguide confined between a poleward turning latitude and an equatorward critical latitude. Forced waves are comma-shaped gyres that resemble observed frontal cyclones, with trailing filaments equatorward of the forcing latitude and standing waves poleward. Even neutral forced Rossby waves converge westerly momentum at the latitude of forcing.
Low-level Updraft Intensification in Response to Environmental Wind Profiles
Authors: Goldacker Nicholas A. , Parker Matthew D. 
Published: June 2021

AbstractSupercell storms can develop a “dynamical response” whereby upward accelerations in the lower troposphere amplify as a result of rotationally induced pressure falls aloft. These upward accelerations likely modulate a supercell’s ability to stretch near-surface vertical vorticity to achieve tornadogenesis. This study quantifies such a dynamical response as a function of environmental wind profiles commonly found near supercells. Self-organizing maps (SOMs) were used to identify recurring low-level wind profile patterns from 20,194 model-analyzed, near-supercell soundings. The SOM nodes with larger 0–500 m storm-relative helicity (SRH) and streamwise vorticity (ωs) corresponded to higher observed tornado probabilities. The distilled wind profiles from the SOMs were used to initialize idealized numerical simulations of updrafts. In environments with large 0–500 m SRH and largeωs, a rotationally induced pressure deficit, increased dynamic lifting, and a strengthened updraft resulted. The resulting upward-directed accelerations were an order of magnitude stronger than typical buoyant accelerations. At 500 m AGL, this dynamical response increased the vertical velocity by up to 25 m s–1, vertical vorticity by up to 0.2 s–1, and pressure deficit by up to 5 hPa. This response specifically augments the near-ground updraft (the midlevel updraft properties are almost identical across the simulations). However, dynamical responses only occurred in environments where 0–500 m SRH andωsexceeded 110 m2s–2and 0.015 s–1, respectively. The presence vs. absence of this dynamical response may explain why environments with higher 0–500 m SRH andωscorrespond to greater tornado probabilities.
On the connection between intermittency and dissipation in ocean turbulence: a multifractal approach
Authors: Isern-Fontanet Jordi , Turiel Antonio 
Published: June 2021

AbstractThe multifractal theory of turbulence is used to investigate the energy cascade in the Northwestern Atlantic ocean. The statistics of singularity exponents of horizontal velocity gradients computed from in situ measurements at 2 km resolution are used to characterize the anomalous scaling of the velocity structure functions at depths between 50 ad 500 m. Here, we show that the degree of anomalous scaling can be quantified using singularity exponents. Observations reveal, on one side, that the anomalous scaling has a linear dependence on the exponent characterizing the strongest velocity gradient and, on the other side, that the slope of this linear dependence decreases with depth. Since the observed distribution of exponents is asymmetric about the mode at all depths, we use an infinitely divisible asymmetric model of the energy cascade, the log-Poisson model, to derive the functional dependence of the anomalous scaling with the exponent of the strongest velocity gradient, as well as the dependence with dissipation. Using this model we can interpret the vertical change of the linear slope between the anomalous scaling and the exponents of the strongest velocity gradients as a change in the energy cascade. This interpretation assumes the validity of the multifractal theory of turbulence, which has been assessed in previous studies.

Background This study evaluated thiamine levels in Indonesian children with congenital heart diseases before and after cardiopulmonary bypass and their relationship with clinical and surgical outcomes. Method A prospective, single center cross-sectional study was conducted to evaluate thiamine levels in 25 children undergoing congenital heart diseases surgery with cardiopulmonary bypass procedure. Thiamine levels were quantified using a high-performance liquid chromatography method. Result Preoperative thiamine deficiency was observed in one subject. Thiamine levels did not differ statistically between nutritional status and clinical outcomes categories. There were no significant changes in thiamine levels before and after cardiopulmonary bypass (median pre versus post (P25–75): 50 ng/mL (59.00–116.00) and 83.00 ng/mL (70.00–101.00), p = 0.84), although a significant reduction in thiamine levels were observed with longer cardiopulmonary bypass duration ( p = 0.017, R = −0.472). Conclusion Thiamine levels were not significantly impacted by cardiac surgery except in patients undergoing extremely long cardiopulmonary bypass duration. However, clinical outcome was not affected by thiamine levels.

Published: June 2021

Background Recent studies suggest increased complications when surgery closely follows corticosteroid injection. The purpose of this study was to understand the occurrence of surgical site infection (SSI), wound complications, and reoperation rates after carpal tunnel release (CTR) when corticosteroid injections were given within 180 days preoperatively. Methods Data were collected from the Truven MarketScan database from 2009 to 2018. Cohorts were created based on preoperative timing of injection (<30, 30-60, 61-90, 91-180 days) and number of injections (0, 1, 2, 3+). Logistic regression was performed to assess the contribution of preoperative injections on 90-day surgical site complications and 1-year reoperation while controlling for demographics and comorbidities. Results Overall, 223 899 patients underwent CTR. Of these, 17 391 (7.76%) had a preoperative injection in the 180 days preceding surgery. Univariate analysis demonstrated a relationship between timing of injections and noninfectious wound complications ( P = .006) and rate of 1-year reoperation ( P = .045). Univariate analysis demonstrated a relationship between number of injections and 1-year reoperation ( P < .001). On multivariate analysis, those receiving injections within 30 days preoperatively had increased rates of SSI ( P = .034) and noninfectious wound complications ( P = .006) compared with those with no injection or at other time points. Patients with 2 ( P = .002) or 3 or more injections ( P < .001) in the 180-day preoperative period had increased odds of 1-year reoperation. Conclusion Our study suggests increased risk of SSI, wound complications, and 1-year reoperation when corticosteroid injections are administered in the 30-day preoperative period. In addition, multiple steroid injections may increase the risk of 1-year reoperation.
