White matter variability, cognition, and disorders: a systematic review
Authors: Forkel Stephanie J. , Friedrich Patrick , Thiebaut de Schotten Michel , Howells Henrietta 
Published: November 2021

AbstractInter-individual differences can inform treatment procedures and—if accounted for—have the potential to significantly improve patient outcomes. However, when studying brain anatomy, these inter-individual variations are commonly unaccounted for, despite reports of differences in gross anatomical features, cross-sectional, and connectional anatomy. Brain connections are essential to facilitate functional organization and, when severed, cause impairments or complete loss of function. Hence, the study of cerebral white matter may be an ideal compromise to capture inter-individual variability in structure and function. We reviewed the wealth of studies that associate cognitive functions and clinical symptoms with individual tracts using diffusion tractography. Our systematic review indicates that tractography has proven to be a sensitive method in neurology, psychiatry, and healthy populations to identify variability and its functional correlates. However, the literature may be biased, as the most commonly studied tracts are not necessarily those with the highest sensitivity to cognitive functions and pathologies. Additionally, the hemisphere of the studied tract is often unreported, thus neglecting functional laterality and asymmetries. Finally, we demonstrate that tracts, as we define them, are not correlated with one, but multiple cognitive domains or pathologies. While our systematic review identified some methodological caveats, it also suggests that tract–function correlations might still be a promising tool in identifying biomarkers for precision medicine. They can characterize variations in brain anatomy, differences in functional organization, and predicts resilience and recovery in patients.
Issues in clustering algorithm consistency in fixed dimensional spaces. Some solutions for k-means
Authors: Kłopotek Mieczysław A. , Kłopotek Robert A. 
Published: November 2021

AbstractKleinberg introduced an axiomatic system for clustering functions. Out of three axioms, he proposed, two (scale invariance and consistency) are concerned with data transformations that should produce the same clustering under the same clustering function. The so-called consistency axiom provides the broadest range of transformations of the data set. Kleinberg claims that one of the most popular clustering algorithms, k-means does not have the property of consistency. We challenge this claim by pointing at invalid assumptions of his proof (infinite dimensionality) and show that in one dimension in Euclidean space the k-means algorithm has the consistency property. We also prove that in higher dimensional space, k-means is, in fact, inconsistent. This result is of practical importance when choosing testbeds for implementation of clustering algorithms while it tells under which circumstances clustering after consistency transformation shall return the same clusters. Two types of remedy are proposed: gravitational consistency property and dataset consistency property which both hold for k-means and hence are suitable when developing the mentioned testbeds.
Simulation of Counter-Current Spontaneous Imbibition Based on Momentum Equations with Viscous Coupling, Brinkman Terms and Compressible Fluids
Authors: Tantciura Sergei , Qiao Yangyang , Andersen Pål Ø. 
Published: November 2021

AbstractA numerical model is investigated representing counter-current spontaneous imbibition of water to displace oil or gas from a core plug. The model is based on mass and momentum conservation equations in the framework of the theory of mixtures. We extend a previous imbibition model that included fluid–rock friction and fluid–fluid drag interaction (viscous coupling) by including fluid compressibility and Brinkman viscous terms. Gas compressibility accelerated recovery due to gas expansion from high initial non-wetting pressure to ambient pressure at typical lab conditions. Gas compressibility gave a recovery profile with two characteristic linear sections against square root of time which could match tight rock literature experiments. Brinkman terms decelerated recovery and delayed onset of imbibition. Experiments where this was prominent were successfully matched. Both compressibility and Brinkman terms caused recovery deviation from classical linearity with the square root of time. Scaling yielded dimensionless numbers when Brinkman term effects were significant.Article Highlights

Spontaneous imbibition with viscous coupling, compressibility and Brinkman terms.

Viscous coupling reduces spontaneous imbibition rate by fluid–fluid friction.

Brinkman terms delay early recovery and explain seen delayed onset of imbibition.

Gas compressibility accelerates recovery and can be significant at lab conditions.

Gas compressibility gives recovery with two root of time lines as seen for shale.
How personality affects reaction. A mental health behavioral insight review during the Pandemic
Authors: Mourelatos Evangelos 
Published: November 2021

AbstractThe fear caused by the Covid-19 pandemic is changing our psychology and behavior. This ongoing negative event, imposing restrictions such as home isolation and social distancing, can result in heightened anxiety, depression and a sense of loneliness, with immediate effects on mental health. This study investigates adolescents’ reaction to the pandemic, by analyzing the behavioral mental health trends of depression, anxiety and sense of loneliness, in relation to personality traits. After controlling for demographics and family background, our results reveal strong relationships between several personality traits and psychological health indicators, during the pandemic in Greece. A total of 419 secondary school students (aged 12–18) were administered the State-Trait Anxiety Inventory for Children (STAIC), the Child Depression Inventory (CDI), the Big Five Inventory for measuring personality (BFI) and the Children’s Loneliness Questionnaire (CLS) during two time periods within pandemic. Overall, it appears that depression increased significantly in line with the escalation of the pandemic, while anxiety decreased, with the strongest predictors being the personality variables of extraversion, neuroticism and openness. Surprisingly, the study also revealed that the level of extraversion has a positive effect on changes in anxiety, while a negative one on changes in depression. On the other hand, neuroticism and openness seem to negatively correlate with anxiety changes and positively with depression changes. These findings highlight the importance of considering these variables in addressing individuals’ mental health behavior during the Covid-19 pandemic and elucidate the literature by offering a deeper understanding of the strong relationship between personality, depression and anxiety.
Knowing How to Feel: Racism, Resilience, and Affective Resistance
Authors: Rogers Taylor 
Published: November 2021

AbstractThis article explores the affective dimension of resilient epistemological systems. Specifically, I argue that responsible epistemic practice requires affective engagement with nondominant experiences. To begin, I outline Kristie Dotson's account of epistemological resilience whereby an epistemological system remains stable despite counterevidence or attempts to alter it. Then, I develop an account of affective numbness. As I argue, affective numbness can promote epistemological resilience in at least two ways. First, it can reinforce harmful stereotypes even after these stereotypes have been rationally demystified. To illustrate, I examine the stereotype of Black criminality as it relates to false confessions (Lackey 2018). Second, it can encourage “epistemic appropriation” (Davis 2018), which I demonstrate by examining the appropriation of “intersectionality” and #MeToo by white culture. Finally, I conclude that resisting harmful resilience requires affective resistance, or efforts that target numbness via different kinds of affective engagement. I consider Kantian “disinterestedness” as a candidate.
Racialized Forgiveness
Authors: Cherry Myisha 
Published: November 2021

AbstractThis article introduces a concept that I refer to as racialized forgiveness. Cases that exemplify certain conditions that I take as paradigmatic of the problem of racialized forgiveness include instances in which: (a) who is forgiven or not is determined by the race of the offender; (b) praise and criticisms of forgiveness are determined by the race of the victim; and (c) praise and criticisms of forgiveness are, at least implicitly, racially self-serving. I argue that this practice is morally objectionable because of its psychological origins, moral failures, and negative effects. Accordingly, in order to dodge these pitfalls, we need to practice forgiveness differently.

Published: November 2021

AbstractObjectiveTracheostomy is required to ensure a safe airway in open partial horizontal laryngectomies. The presence of the tracheostomy tube can contribute to post-operative dysphagia. This study aimed to evaluate the effects of a circumferential tracheostomy technique on swallowing.MethodsA retrospective study was conducted of patients who underwent open partial horizontal laryngectomies between April 2018 and June 2019. Patients were divided into two groups based on the tracheostomy technique: group 1 had two stitches from the inferior tracheal ring to the skin; group 2 had circumferential fixation of the trachea to the skin. Demographic information, surgical data, post-operative rehabilitation course and complication details were collected and analysed.ResultsTwenty-four patients were enrolled. Patients in group 2 had significant improvement in the initial phases of swallowing rehabilitation.ConclusionTracheostomy with anchorage of the trachea to the skin by circumferential stitches could allow early removal of the tracheal tube, with a better swallowing outcome.

AbstractObjectivesTo correlate computed tomography findings and endoscopic localisation of the anterior ethmoidal artery during surgery, and to analyse the intranasal landmarks and abnormalities of the artery.MethodThe anterior ethmoidal artery was studied with high-resolution computed tomography and endoscopic surgery in 30 patients undergoing functional endoscopic sinus surgery (group A), and with endoscopic dissection on 30 human cadavers (group B).ResultsThe anterior ethmoidal artery was demonstrated on computed tomography in 25 patients and intra-operatively in 12 (group A). It was identified in 26 cadavers (group B). Dehiscence of bony canal and branching was noted in 10.53 per cent of cases. The mean (± standard deviation) intranasal length of the anterior ethmoidal artery was 7.29 (± 1.21) mm, the distance of the artery from the axilla of the middle turbinate was 16.24 (± 2.75) mm, and the mean distance from the ground lamella was 8.97 (± 1.46) mm.ConclusionHigh-resolution computed tomography scanning prior to functional endoscopic sinus surgery is mandatory to identify the anterior ethmoidal artery. Endoscopically, the axilla of the middle turbinate and the ground lamella can serve as dependable reference points to identify the artery. Cadaver dissection improves understanding of anatomy.

Published: November 2021

AbstractOne of the three Critically Endangered and endemic primate species in Viet Nam, Delacour's langur Trachypithecus delacouri, is restricted to the north of the country. The largest remaining population is in Van Long Nature Reserve, Ninh Binh Province, and the second largest is in nearby Kim Bang Protection Forest, Ha Nam Province, with other populations believed to be too small for recovery. The population in Van Long has been well studied but the status of that of Kim Bang has not previously been adequately evaluated. To address this, a survey was conducted during 10 August–7 October 2018. In total, we recorded 13 groups comprising a total of at least 73 individuals, almost doubling the highest number reported in previous studies. We documented six new groups in Lien Son and Ba Sao communes in Kim Bang. Our findings indicate there is a high likelihood that Delacour's langur population in Kim Bang will recover and could be important for the long-term conservation of this Critically Endangered species. However, immediate and appropriate conservation measures need to be implemented to protect the population from major anthropogenic threats, namely poaching and habitat destruction, detected during our survey.
Dietary protein supplementation results in molecular and cellular changes related to T helper type 2 immunity in the lung and small intestine in lactating rats re-infected with Nippostrongylus brasiliensis

AbstractAcquired immunity to gastrointestinal nematodes reduces during late pregnancy and lactation which is known as periparturient relaxation of immunity (PPRI). Protein supplementation reduces the degree of PPRI in a rat model re-infected with Nippostrongylus brasiliensis, but the underlying molecular mechanisms have yet to be elucidated. Here, we hypothesized that protein supplementation will enhance T helper type 2 immunity (Th2) in the lung and small intestine. Nulliparous Sprague-Dawley rats were given a primary infection of N. brasiliensis prior to mating and restrictedly fed diets with either low protein (LP) or high protein (HP) during pregnancy and lactation. Dams were secondary infected with N. brasiliensis on day 2 post-parturition, and histology and gene expression were analysed for tissue samples collected at days 5, 8 and 11. Genes related to Th2 immunity in the lung, Retnla, Il13 and Mmp12, and in the intestine, Retnlb, were upregulated in HP dams compared to LP dams, which indicates the effect of dietary protein on Th2 immunity. HP dams also had increased splenic CD68+ macrophage populations compared to LP dams following secondary infection, suggesting enhanced immunity at a cellular level. Our data assist to define strategic utilization of nutrient supply in mammals undergoing reproductive and lactational efforts.

Published: November 2021

AbstractBackgroundTourette disorder (TD), hallmarks of which are motor and vocal tics, has been related to functional abnormalities in large-scale brain networks. Using a fully data driven approach in a prospective, case–control study, we tested the hypothesis that functional connectivity of these networks carries a neural signature of TD. Our aim was to investigate (i) the brain networks that distinguish adult patients with TD from controls, and (ii) the effects of antipsychotic medication on these networks.MethodsUsing a multivariate analysis based on support vector machine (SVM), we developed a predictive model of resting state functional connectivity in 48 patients and 51 controls, and identified brain networks that were most affected by disease and pharmacological treatments. We also performed standard univariate analyses to identify differences in specific connections across groups.ResultsSVM was able to identify TD with 67% accuracy (p = 0.004), based on the connectivity in widespread networks involving the striatum, fronto-parietal cortical areas and the cerebellum. Medicated and unmedicated patients were discriminated with 69% accuracy (p = 0.019), based on the connectivity among striatum, insular and cerebellar networks. Univariate approaches revealed differences in functional connectivity within the striatum in patients v. controls, and between the caudate and insular cortex in medicated v. unmedicated TD.ConclusionsSVM was able to identify a neuronal network that distinguishes patients with TD from control, as well as medicated and unmedicated patients with TD, holding a promise to identify imaging-based biomarkers of TD for clinical use and evaluation of the effects of treatment.
Toward greater sustainability: how investing in soil health may enhance maize productivity in Southern Africa

Published: November 2021

AbstractClimate change and soil fertility decline are major threats to smallholder farmers' food and nutrition security in southern Africa, and cropping systems that improve soil health are needed to address these challenges. Cropping systems that invest in soil organic matter, such as no-tillage (NT) with crop residue retention, have been proposed as potential solutions. However, a key challenge for assessing the sustainability of NT systems is that soil carbon (C) stocks develop over long timescales, and there is an urgent need to identify trajectory indicators of sustainability and crop productivity. Here we examined the effects of NT as compared with conventional tillage without residue retention on relationships between soil characteristics and maize (Zea maysL.) productivity in long-term on-farm and on-station trials in Zimbabwe. Our results show that relationships between soil characteristics and maize productivity, and the effects of management on these relationships, varied with soil type. Total soil nitrogen (N) and C were strong predictors of maize grain yield and above-ground biomass (i.e., stover) in the clayey soils, but not in the sandy soils, under both managements. This highlights context-specific benefits of management that fosters the accumulation of soil C and N stocks. Despite a strong effect of NT management on soil C and N in sandy soils, this accrual was not sufficient to support increased crop productivity in these soils. We suggest that sandy soils should be the priority target of NT with organic resource inputs interventions in southern Africa, as mineral fertilizer inputs alone will not halt the soil fertility decline. This will require a holistic management approach and input of C in various forms (e.g., biomass from cover crops and tree components, crop residues, in combination with mineral fertilizers). Clayey soils on the other hand have greater buffering capacity against detrimental effects of soil tillage and low C input.
Exploring foundational convergence between the Islamic law of armed conflict and modern international humanitarian law: Evidence from al-Shaybani's Siyar al-Kabir
Authors: Çakmak Cenap , Güneysu Gökhan 
Published: November 2021

AbstractThis paper compares and contrasts the Islamic law of armed conflict with the modern international humanitarian law, with the view of identifying foundational similarities between these two separate canons, drawing extensively from al-Siyar al-Kabir. To this end, it raises the question as to whether the Islamic law of armed conflict is compatible with its modern counterpart, and, if it is, to what extent. To address these interlinked questions, the study departs from the premise that in order to identify resemblance, it is necessary to enquire into the foundations (both legal and philosophical) of the Islamic and contemporary approaches vis-à-vis armed conflicts.
Evaluation of CloudSat Radiative Kernels Using ARM and CERES Observations and ERA5 Reanalysis

Published: November 2021

AbstractDespite the widespread use of the radiative kernel technique for studying radiative feedbacks and radiative forcings, there has not been any systematic, observation‐based validation of the radiative kernel method. Here, we utilize observed and reanalyzed radiative fluxes and atmospheric profiles from the Atmospheric Radiation Measurement (ARM) program and ERA5 reanalysis to assess a set of observation‐based radiative kernels from CloudSat for six ARM sites. The CloudSat radiative kernels, convoluted with the ERA5 state variables, can almost perfectly reconstruct the monthly anomalies of shortwave (SW) and longwave (LW) radiative fluxes in ERA5 at the surface (SFC) and top‐of‐atmosphere (TOA) with correlations significantly being greater than 0.95. The biases of kernel‐estimated flux anomalies calculated using the ARM‐observed state variables can be more than twice as large when compared with the ARM‐observed surface flux anomalies and Clouds and Earth's Radiant Energy System observed anomalies at the TOA. Generally, clouds contribute to most (>60%) of the variance of flux anomalies at Southern Great Plain (SGP), Tropical Western Pacific (TWP), and Eastern North Atlantic (ENA), and surface albedo dominates (>69%) the variance of SW flux anomalies at North Slope of Alaska. The radiative kernels exhibit the lowest correlation (r∼[0.55,0.85]) when reconstructing SFC LW flux anomalies at SGP, TWP, and ENA, whose biases are related to the possibility that the kernels may not fully capture the characteristics associated with Madden‐Julian oscillation and El Niño‐Southern Oscillation at TWP and the presence of clouds at SGP and ENA.

AbstractChorus waves outside the plasmapause influence the Earth's radiation belt dynamics by interacting with energetic electrons via cyclotron and Landau resonance. Recent numerical diffusion experiments indicate that the diffusion process is sensitive to the spatial and temporal scale of variability in the wave‐particle interaction, which is reported to be more efficient than that based on the traditional average model. Using Van Allen Probes A and B data from November 2012 to July 2019, the spatial and temporal scale size of chorus waves are calculated by the correlation between the wave amplitudes detected by two satellites with varying spatial separation or time lag. We found that, the chorus wave is incoherent when the spatial extent is greater than 433 km or the time lag lasts ∼10 s, which are significantly smaller than that of plasmaspheric hiss. In addition, the spatial correlations of chorus tend to be higher near noon or with lower geomagnetic activity. The temporal correlations of chorus are always statistically near zero, which are not influenced by the location and geomagnetic activity. Our results can help refine the model of the interactions between energetic particles and chorus waves in the radiation belt.
