Published: January 2022

Chronic Pain (CP) is prevalent in industrialized countries and stands among the top 10 causes of disability. Given the widespread problems of pharmacological treatments such as opioids, a need to find alternative therapeutic approaches has emerged. Virtual Reality (VR) has shown potential as a non-pharmacological alternative for controlling pain over the past 20 years. The effectiveness of VR has been demonstrated in treating CP, and it has been suggested that VR’s analgesic effects may be associated with the Sense of Embodiment (SoE): the sensation of being inside, having and controlling a virtual body in VR. Studies have shown correlations among brain signals, reported pain and a SoE, and correlations have been observed between using an avatar in VR and pain alleviation among CP patients. However, little has been published about the changes in brain physiology associated with having an avatar in VR, and current published studies present methodological issues. Defining a proper methodology to investigate the underlying brain mechanisms of pain, a SoE associated with having an avatar in VR, and its effect on reducing pain in CP patients is key to the emerging field of VR-analgesia. Here, we propose an intervention trial design (test/intervention/test) to evaluate the effects of having a virtual avatar in VR on pain levels and SoE in CP patients using Electroencephalogram (EEG) recordings. Resting-state EEG recordings, perceived pain levels, and SoE scores will be collected before and after the VR intervention. Patients diagnosed with CP will be recruited from local pain clinics and pseudo-randomly assigned to one of two groups—with or without an avatar. Patients will experience a 10-min VR intervention built to treat CP while their EEG signals are recorded. In articulating the study procedure, we propose a framework for future studies that explores the mechanisms of VR-analgesia in patients with chronic pain.

Published: January 2022

The hydrodynamic dispersion tensor (HDT) of a porous medium is a key parameter in engineering and environmental sciences. Its knowledge allows for example, to accurately predict the propagation of a pollution front induced by a surface (or subsurface) flow. This paper proposes a new mathematical model based on inverse problem-solving techniques to identify the HDT (noted D=) of the studied porous medium. We then showed that in practice, this new model can be written in the form of an integrated optimization algorithm (IOA). The IOA is based on the numerical solution of the direct problem (which solves the convection–diffusion type transport equation) and the optimization of the error function between the simulated concentration field and that observed at the application site. The partial differential equations of the direct model were solved by high resolution of (Δx=Δy=1 m) Lattice Boltzmann Method (LBM) whose computational code is named HYDRODISP-LBM (HYDRO-DISpersion by LBM). As for the optimization step, we opted for the CMA-ES (Covariance Matrix Adaptation-Evolution Strategy) algorithm. Our choice for these two methods was motivated by their excellent performance proven in the abundant literature. The paper describes in detail the operation of the coupling of the two computer codes forming the IOA that we have named HYDRODISP-LBM/CMA-ES. Finally, the IOA was applied at the Beauvais experimental site to identify the HDT D=. The geological analyzes of this site showed that the tensor identified by the IOA is in perfect agreement with the characteristics of the geological formation of the site which are connected with the mixing processes of the latter.

Currently, Autism Spectrum Disorder has gained greater visibility. Being a global developmental disorder and knowing its implications for children's lives, emerged the need for new therapies and approaches to address the needs of autistic children has arisen in a way that can fully develop. In this context comes the equine therapy with a proposal of therapy linked to psychomotricity, in which, through psychomotor development, socialization, learning and affectivity, these children can have greater autonomy in the ir lives. In this way, the general objective of this work is to verify the contribution of Equoterapia in the psychomotor development of the child with Autism Spectrum Disorder (ASD) from the perspective of the Physical Education teacher and the Psychologist. As methodology, we applied an open questionnaire to five professionals who work in equine therapy centers in São Paulo and work or have worked with children with ASD. For the treatment of the data we used the thematic analysis where we chose five themes to analyze. As results we could observe that as the literature states, Equine therapy, under the view of psychologists and physical education teacher, brings affective, cognitive and motor benefits to ASD practitioners, although the centers use heterogeneous approach and evaluative methods. Regardless of the factors questioned in this work, it was evident the dedication of all the professionals involved and, above all, the incredible experience of seeing these children perceiving a new world with the horse and through this the process of self-discovery as people in the world.

Reward learning and statistical learning independently influence attentional priority of salient distractors in visual search
Authors: Le Pelley Mike E. , Ung Rhonda , Mine Chisato , Most Steven B. , Watson Poppy , Pearson Daniel , Theeuwes Jan 
Published: January 2022

AbstractExisting research demonstrates different ways in which attentional prioritization of salient nontarget stimuli is shaped by prior experience: Reward learning renders signals of high-value outcomes more likely to capture attention than signals of low-value outcomes, whereas statistical learning can produce attentional suppression of the location in which salient distractor items are likely to appear. The current study combined manipulations of the value and location associated with salient distractors in visual search to investigate whether these different effects of selection history operate independently or interact to determine overall attentional prioritization of salient distractors. In Experiment 1, high-value and low-value distractors most frequently appeared in the same location; in Experiment 2, high-value and low-value distractors typically appeared in distinct locations. In both experiments, effects of distractor value and location were additive, suggesting that attention-promoting effects of value and attention-suppressing effects of statistical location-learning independently modulate overall attentional priority. Our findings are consistent with a view that sees attention as mediated by a common priority map that receives and integrates separate signals relating to physical salience and value, with signal suppression based on statistical learning determined by physical salience, but not incentive salience.

ABSTRACT

Objectives:
An alarming rate of adverse perinatal outcomes as well as maternal deaths has been reported worldwide during this pandemic. It would be prudent to start thinking on the lines of acute or chronic intrauterine fetal hypoxia due to placental microvascular pathology or villitis caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection. Autopsy studies of deceased patients with severe COVID-19 have revealed the presence of diffuse pulmonary alveolar damage, thrombosis, and microvascular injuries. It is expected that similar pathological features such as microvascular injuries could be found in the placenta of infected pregnant women.

Materials and Methods:
Placentas of singleton pregnancies from 42 SARS-CoV-2 positive mothers delivered at term were submitted for histopathological examination. Those with multifetal gestation, hypertensive disorder, fetal growth restriction, structural or chromosomal anomalies in the fetus, thrombophilia, prolonged prelabor rupture of membranes, and placenta accreta spectrum were excluded from the study. Histopathological examination was done by two pathologists independently and only those results concurred by both were reported. Histopathological features and corresponding neonatal outcome were analyzed.

Results:
Reports of 42 placentas from patients with SARS-CoV-2, delivered at term (37–40 weeks) were analyzed in our study. Features of maternal vascular malperfusions (MVM) were present in 45% (n = 19) cases. Features of fetal vascular malperfusions (FVM) were present in 23.8% (n = 10) cases. There were 47.6% (n = 20) cases showing at least one feature of acute inflammatory pathology (AIP) and 42.8% (n = 18) showing features of chronic inflammatory pathology (CIP). Neonatal respiratory distress syndrome was found in 19% (n = 8) of the neonates. Correspondingly, nearly all placentas (n = 7) of these neonates showed features of MVM, FVM, AIP and CIP. There was no maternal or neonatal mortality in our study group.

Conclusion:
The main findings of our study include maternal as well as fetal vascular malperfusions and placental inflammatory pathology. These findings provide an outline for better understanding of etiological factors and pathogenesis of adverse perinatal outcomes in SARS-CoV-2 infection.
Kneser’s theorem in -finite abelian groups
Authors: Bienvenu Pierre-Yves , Hennecart François 
Published: January 2022

AbstractLet G be a
$\sigma $
-finite abelian group, i.e.,
$G=\bigcup _{n\geq 1} G_n$
where
$(G_n)_{n\geq 1}$
is a nondecreasing sequence of finite subgroups. For any
$A\subset G$
, let
$\underline {\mathrm {d}}( A ):=\liminf _{n\to \infty }\frac {|A\cap G_n|}{|G_n|}$
be its lower asymptotic density. We show that for any subsets A and B of G, whenever
$\underline {\mathrm {d}}( A+B )<\underline {\mathrm {d}}( A )+\underline {\mathrm {d}}( B )$
, the sumset
$A+B$
must be periodic, that is, a union of translates of a subgroup
$H\leq G$
of finite index. This is exactly analogous to Kneser’s theorem regarding the density of infinite sets of integers. Further, we show similar statements for the upper asymptotic density in the case where
$A=\pm B$
. An analagous statement had already been proven by Griesmer in the very general context of countable abelian groups, but the present paper provides a much simpler argument specifically tailored for the setting of
$\sigma $
-finite abelian groups. This argument relies on an appeal to another theorem of Kneser, namely the one regarding finite sumsets in an abelian group.
Operator valued analogues of multidimensional Bohr’s inequality
Authors: Allu Vasudevarao , Halder Himadri 
Published: January 2022

AbstractLet
$\mathcal {B}(\mathcal {H})$
be the algebra of all bounded linear operators on a complex Hilbert space
$\mathcal {H}$
. In this paper, we first establish several sharp improved and refined versions of the Bohr’s inequality for the functions in the class
$H^{\infty }(\mathbb {D},\mathcal {B}(\mathcal {H}))$
of bounded analytic functions from the unit disk
$\mathbb {D}:=\{z \in \mathbb {C}:|z|<1\}$
into
$\mathcal {B}(\mathcal {H})$
. For the complete circular domain
$Q \subset \mathbb {C}^{n}$
, we prove the multidimensional analogues of the operator valued Bohr-type inequality which can be viewed as a special case of the result by G. Popescu [Adv. Math. 347 (2019), 1002–1053] for free holomorphic functions on polyballs. Finally, we establish the multidimensional analogues of several improved Bohr’s inequalities for operator valued functions in Q.

ABSTRACT.
The malaria vector, Anopheles stephensi, which is typically restricted to South Asia and the Middle East, was recently detected in the Horn of Africa. Addressing the spread of this vector could involve integrated vector control that considers the status of insecticide resistance of multiple vector species in the region. Previous reports indicate that the knockdown resistance mutations (kdr) in the voltage-gated sodium channel (vgsc) are absent in both pyrethroid-resistant and pyrethroid-sensitive An. stephensi in eastern Ethiopia; however, similar information about other vector species in the same areas is limited. In this study, kdr and the neighboring intron were analyzed in An. stephensi, An. arabiensis, and Culex pipiens s.l. collected between 2016 and 2017 to determine the evolutionary history of kdr in eastern Ethiopia. A sequence analysis revealed that all of Cx. pipiens s.l. (N = 42) and 71.6% of the An. arabiensis (N = 67) carried kdr L1014F, which is known to confer target-site pyrethroid resistance. Intronic variation was only observed in An. stephensi (six segregating sites, three haplotypes), which was previously shown to have no kdr mutations. In addition, no evidence of non-neutral evolutionary processes was detected at the An. stephensi kdr intron, thereby further supporting the target-site mechanism not being a major resistance mechanism in this An. stephensi population. Overall, these results show key differences in the evolution of target-site pyrethroid/dichlorodiphenyltrichloroethane resistance mutations in populations of vector species from the same region. Variations in insecticide resistance mechanism profiles between eastern Ethiopian mosquito vectors may lead to different responses to insecticides used in integrated vector control.

ABSTRACT.
Schistosomiasis control requires multisectoral approaches including praziquantel treatment, access to safe water, sanitation and hygiene, and health education. Community input can help ensure health education programs are culturally appropriate to effectively direct protective behavior change. This study reports on the three-stage development of an education program for Malagasy children, with an impact evaluation on their knowledge, attitudes, and practices (KAP) related to intestinal schistosomiasis. A cross-sectional study took place in 2017 with follow-up in 2018 in the hard-to-reach Marolambo district, Madagascar. A novel schistosomiasis education program (SEP) was designed in collaboration with researchers, stakeholders, and local community and included cartoon books, games, songs, puzzles, and blackboard lessons, costing $10 USD per school. KAP questionnaires were completed by 286 children pre-SEP and 273 children post-SEP in 2017, and by 385 and 337 children pre-SEP and post-SEP, respectively, in 2018. Improvements were observed in responses to all questions between pre- and post-education answers in 2017 (53–77%, P < 0.0001) and 2018 (72–98%, P < 0.0001) and in the pre-education answers between years (53–72%, P < 0.0001). Praziquantel mass drug administration attendance improved, rising from 64% to 91% (P < 0.0001), alongside improved latrine use, from 89% to 96% (P = 0.005). This community-consulted and -engaged SEP resulted in substantial improvements in children’s understanding of schistosomiasis, with improvements in praziquantel uptake and latrine use. Socioculturally tailored education programs can help gain schistosomiasis control. Continued investment in SEP will help promote the future well-being of children through increased participation in control and treatment activities.

Published: January 2022

AbstractCarbohydrate translocation, which follows anatomical and developmental patterns, is ruled by source-sink relations where energy-containing compounds are moved from sources of production to sinks of utilization. Seasonal carbohydrate concentrations in various tree parts were measured and compared in 10 cm (4 in) trunk diameter live oaks (Quercus virginianaP. Miller). Tissue samples from roots, trunks, twigs and leaves were collected from three-year-old field-grown trees on four dates throughout the 2005–2006 seasons. Laboratory analyses of glucose and starch were performed, and values were compared and contrasted according to sample location and time of year. Glucose levels were significantly higher in leaves during the winter (P≤ 0.001), while starch concentrations were significantly higher in root and trunk tissues during the spring and winter assessments (P≤ 0.001). Carbohydrate concentrations varied among tissues sampled within the tree. This study provides valuable information on the spatial and temporal partitioning of energy reserves, glucose and starch, in live oak so that arborists will have a better understanding of tree vitality, and the effects and environmental impacts of arboricultural treatments.
A framework to evaluate and elucidate the driving mechanisms of coastal sea surface pCO2 seasonality using an ocean general circulation model (MOM6-COBALT)

Published: January 2022

Abstract. The temporal variability of the sea surface partial pressure of CO2
(pCO2) and the underlying processes driving this variability are poorly
understood in the coastal ocean. In this study, we tailor an existing method
that quantifies the effects of thermal changes, biological activity, ocean
circulation and freshwater fluxes to examine seasonal pCO2 changes in
highly variable coastal environments. We first use the Modular Ocean Model
version 6 (MOM6) and biogeochemical module Carbon Ocean Biogeochemistry And
Lower Trophics version 2 (COBALTv2) at a half-degree resolution to simulate
coastal CO2 dynamics and evaluate them against pCO2 from the
Surface Ocean CO2 Atlas database (SOCAT) and from the continuous
coastal pCO2 product generated from SOCAT by a two-step neuronal
network interpolation method (coastal Self-Organizing Map Feed-Forward neural Network SOM-FFN, Laruelle et al., 2017). The
MOM6-COBALT model reproduces the observed spatiotemporal
variability not only in pCO2 but also in sea surface temperature, salinity and
nutrients in most coastal environments, except in a few specific regions
such as marginal seas. Based on this evaluation, we identify coastal regions
of “high” and “medium” agreement between model and coastal SOM-FFN where the
drivers of coastal pCO2 seasonal changes can be examined with
reasonable confidence. Second, we apply our decomposition method in three
contrasted coastal regions: an eastern (US East Coast) and a western (the
Californian Current) boundary current and a polar coastal region (the
Norwegian Basin). Results show that differences in pCO2 seasonality in
the three regions are controlled by the balance between ocean circulation and
biological and thermal changes. Circulation controls the pCO2 seasonality in the Californian Current; biological activity controls
pCO2 in the Norwegian Basin; and the interplay between biological
processes and thermal and circulation changes is key on the US East Coast.
The refined approach presented here allows the attribution of pCO2 changes with small residual biases in the coastal ocean, allowing for future
work on the mechanisms controlling coastal air–sea CO2 exchanges and
how they are likely to be affected by future changes in sea surface
temperature, hydrodynamics and biological dynamics.
Un viaje hacia el pasado mexicano: Diego Cañedo, seguidor de H. G. Wells
Authors: Arteaga Martínez Alejandro 
Published: January 2022

Palamás, Echevete y yo o el lago asfaltado (Palamás, Echevete and I or the asphalted lake), Mexican Diego Cañedo’s second novel (1945), elaborates the time travel to the Mexican past. The sci-fi theme of the novel sustains a social criticism, and imitates H. G. Wells’ The Time Machine plot. In this essay, the sociocritical part of Cañedo’s work is studied, on one hand, because it seems to respond to the social problems of the period 1934-1946; and, on the other hand, because the relations established with Wells’ novel.
