Low-Intensity Resistance Training with Blood Flow Restriction Improves Metabolic Parameters in Men with Metabolic Syndrome
Authors:   The Urals State University of Physical Culture, Sverchkov Vadim V. , Bykov Evgeniy V.
Published: October 2023

Resistance training with blood flow restriction using inflatable cuffs or elastic bands produces a partial occlusion of the vessels of the exercising muscles. Compared to high-intensity resistance training, blood flow restriction training markedly reduces the mechanical load, while causing a similar increase in muscle mass and strength. Thus, this method is an effective training protocol for people with disabilities. Recent studies have shown that blood flow restriction training has beneficial effects on glucose metabolism and promotes mitochondrial biogenesis. Therefore, it can be considered as a valuable alternative to exercise for people with metabolic syndrome, a disorder characterized by impaired glucose metabolism, decreased skeletal muscle mass and progressive sarcopenia. The purpose of this research was to evaluate the effect of low-intensity resistance training with blood flow restriction on the metabolic parameters in men with metabolic syndrome. Materials and methods. The study involved 45 non-exercising men (mean age 35.2 ± 6.4 years) with metabolic syndrome. The participants were divided into three groups: low-intensity resistance training with blood flow restriction; high-intensity resistance training without blood flow restriction; low-intensity resistance training without blood flow restriction. Before and after the training course (12 weeks), blood plasma levels of glucose, triglycerides and high-density lipoproteins were assessed, as well as systolic blood pressure, waist circumference and metabolic syndrome severity z-score. Results. A statistically significant (p ˂ 0.05) decrease in all parameters was found in the groups of low-intensity resistance training with blood flow restriction and high-intensity resistance training. In the group of low-intensity resistance training without blood flow restriction, no statistically significant changes were identified (p ˃ 0.05). Thus, the research found that low-intensity resistance training with blood flow restriction improves the metabolic profile of men with metabolic syndrome and can, therefore, be used to prevent and treat metabolic disorders.

Published: October 2023

The research was conducted by a member of the 60th Russian Antarctic Expedition at the all-yearround Mirny Station. The purpose was to study the effect of changed patterns of tobacco smoking on the adaptive capabilities of polar station staff. Materials and methods. Adaptive capabilities were evaluated using the method of cardio-respiratory synchronism, assessing the index of regulatory and adaptive status (IRAS). It is based on recording the synchronization parameters of controlled high respiratory rate and heart rate. IRAS dynamics was compared in four subjects (three regular smokers and one non-smoker as a control) over the course of one year of wintering. The subjects had comparable anthropometric data, health status and working conditions at the station. They were exposed to a similar amount of adverse environmental factors due to their professional activities and lived according to the station’s standard schedule without any personalized changes in their day regimen. Smoking patterns were determined by independent decisions of each expedition member and by the size of personal stocks of tobacco products prepared for the wintering. Results. In polar expedition members faced with smoking cessation or inability to adequately meet this need, IRAS decrease, being a marker of human adaptive capabilities, allowed us to determine the relationship between pronounced changes in the dynamics of regular tobacco smoking and body’s adaptive capabilities. The authors assume that organizational arrangements (sufficient stocks of nicotine-containing products such as cigarettes and tobacco) at the station as well as educational activities (dissuading expedition members from abrupt non-supervised changes in their smoking patterns during Antarctic wintering and properly explaining the reasons why such actions are undesirable) may contribute to improving the health of expedition members and optimizing their living conditions at the polar station. Completing a smoking cessation programme with medical supervision in advance (while preparing for a polar expedition) as well as upon returning from the station (at the end of the adaptation period) can be recommended.

Published: October 2023

Aim: The ongoing global COVID-19 pandemic, caused by the SARS-CoV-2 virus, has generated significant apprehensions in maternal-fetal medicine. Initially considered to affect the respiratory system primarily, recent findings have indicated that the pandemic has far-reaching implications for various physiological functions, particularly in pregnant individuals. This study focused on examining the influence of COVID-19 on placental histopathology in pregnant women infected with SARS-CoV-2. Material and Methods: We conducted a comparative study involving two groups of pregnant women with similar demographic characteristics: a group testing positive for COVID-19 (n=31) and a control group of COVID-19-negative pregnant women (n=31). After delivery, placental tissues were collected and subjected to comprehensive histopathological examination to determine any potential alterations in the placenta induced by SARS-CoV-2 infection. Results: Our study revealed substantial histopathological alterations in pregnant women with COVID-19 placentas. Notably, the COVID-19 group displayed a higher incidence of cesarean deliveries, possibly due to concerns related to maternal-fetal transmission and respiratory complications. Furthermore, neonates born to mothers in the COVID-19 group had significantly lower birth weights. Several placental histopathological changes, including villous fibrin deposits, thrombosis, intervillous hemorrhage, agglutination, avascular fibrotic villi, and syncytial knots, were markedly increased in the COVID-19 group, indicating compromised fetal blood circulation. Although not statistically significant, trends toward elevated villous infarction, fetal vascular malperfusion, and chorioamnionitis were observed. Conclusion: Our study underscores the potential risks associated with COVID-19 on placental health, maternal well-being, and neonatal outcomes. We must understand the underlying physiological mechanisms behind these pathological changes to provide optimal maternal-fetal care during this ongoing crisis. Comprehensive and multicentric studies are urgently required to confirm and expand our findings.

The 107 GHz Methanol Transition Is a Dasar in G0.253+0.016

We present observations of population anti-inversion in the 31 − 40
A
+ transition of CH3OH (methanol) at 107.013831 GHz toward the Galactic center cloud G0.253+0.016 (“The Brick”). Anti-inversion of molecular level populations can result in absorption lines against the cosmic microwave background (CMB) in a phenomenon known as a “dasar.” We model the physical conditions under which the 107 GHz methanol transition dases and determine that dasing occurs at densities below 106 cm−3 and column densities between 1013 and 1016 cm−2. We also find that for this transition, dasing does not strongly depend on the gas kinetic temperature. We evaluate the potential of this tool for future deep galaxy surveys. We note that other works have already reported absorption in this transition (e.g., in NGC 253), but we provide the first definitive evidence that it is absorption against the CMB rather than against undetected continuum sources.
Nearby SNR: A Possible Common Origin of Multi-messenger Anomalies in the Spectra, Ratios, and Anisotropy of Cosmic Rays

Multi-messenger anomalies, including spectral hardening or excess of nuclei, leptons, ratios of

and B/C, and anisotropic reversal, have been observed in past years. The AMS-02 experiment also revealed different spectral breaks for positrons and electrons at 284 GeV and beyond tera electron volts, respectively. It is natural to ask whether all those anomalies originate from one unified physical scenario. In this work, the spatially dependent propagation (SDP) with a nearby supernova remnant (SNR) source is adopted to reproduce the abovementioned anomalies. There possibly exists a dense molecular cloud (DMC) around SNRs and the secondary particles can be produced by pp collision or fragmentation between the accelerated primary cosmic rays and DMC. As a result, the spectral hardening for primary and secondary particles and ratios of B/C and

p

p

can be well reproduced. Due to the energy loss at the source age of 330 kyr, the characteristic spectral break-off for a primary electron is at about 1 TeV as hinted at by the measurements. The secondary positrons and electrons from charged pion take up 5% of energy from their mother particles, so the positron spectrum has a break-off at ∼250 GeV. Therefore, the different spectral breaks for positrons and electrons together with other anomalies can be fulfilled in this unified physical scenario. More interesting is that we also obtain the featured structures as spectral break-offs at 5 TeV for secondary particles of Li, Be, and B, which can be used to verify our model. We hope that those tagged structures can be observed by the new generation of spaceborne experiment HERD in the future.

A growing number of far-infrared (FIR) bright sources completely invisible in deep extragalactic optical surveys hint at an elusive population of z > 4 dusty, star-forming galaxies. Cycle 1 JWST surveys are now detecting their rest-frame optical light, which provides key insight into their stellar properties and statistical constraints on the population as a whole. This work presents the JWST Near Infrared Camera (NIRCam) counterpart from the COSMOS-Web survey to an FIR SCUBA-2 and Atacama Large Millimeter/submillimeter Array (ALMA) source, AzTECC71, which was previously undetected at wavelengths shorter than 850 μm. AzTECC71, among the reddest galaxies in COSMOS-Web with F277W − F444W ∼ 0.9, is undetected in NIRCam/F150W and F115W and fainter in F444W than other submillimeter galaxies identified in COSMOS-Web by 2–4 magnitudes. This is consistent with the system having both a lower stellar mass and higher redshift than the median dusty, star-forming galaxy. With deep ground- and space-based upper limits combined with detections in F277W, F444W, and the FIR including ALMA Band 6, we find a high probability (99%) that AzTECC71 is at z > 4 with

This population of luminous, infrared galaxies at z > 4 is largely unconstrained but comprises an important bridge between the most extreme dust-obscured galaxies and more typical high-redshift star-forming galaxies. If further FIR-selected galaxies that drop out of the F150W filter in COSMOS-Web have redshifts z > 4 like AzTECC71, then the volume density of such sources may be ∼3–10 × greater than previously estimated.
Applicability domains of neural networks for toxicity prediction

Published: October 2023

In this paper, the term "applicability domain" refers to the range of chemical compounds for which the statistical quantitative structure-activity relationship (QSAR) model can accurately predict their toxicity. This is a crucial concept in the development and practical use of these models. First, a multidisciplinary review is provided regarding the theory and practice of applicability domains in the context of toxicity problems using the classical QSAR model. Then, the advantages and improved performance of neural networks (NNs), which are the most promising machine learning algorithms, are reviewed. Within the domain of medicinal chemistry, nine different methods using NNs for toxicity prediction were compared utilizing 29 alternative artificial intelligence (AI) techniques. Similarly, seven NN-based toxicity prediction methodologies were compared to six other AI techniques within the realm of food safety, 11 NN-based methodologies were compared to 16 different AI approaches in the environmental sciences category and four specific NN-based toxicity prediction methodologies were compared to nine alternative AI techniques in the field of industrial hygiene. Within the reviewed approaches, given known toxic compound descriptors and behaviors, we observed a difficulty in being able to extrapolate and predict the effects with untested chemical compounds. Different methods can be used for unsupervised clustering, such as distance-based approaches and consensus-based decision methods. Additionally, the importance of model validation has been highlighted within a regulatory context according to the Organization for Economic Co-operation and Development (OECD) principles, to predict the toxicity of potential new drugs in medicinal chemistry, to determine the limits of detection for harmful substances in food to predict the toxicity limits of chemicals in the environment, and to predict the exposure limits to harmful substances in the workplace. Despite its importance, a thorough application of toxicity models is still restricted in the field of medicinal chemistry and is virtually overlooked in other scientific domains. Consequently, only a small proportion of the toxicity studies conducted in medicinal chemistry consider the applicability domain in their mathematical models, thereby limiting their predictive power to untested drugs. Conversely, the applicability of these models is crucial; however, this has not been sufficiently assessed in toxicity prediction or in other related areas such as food science, environmental science, and industrial hygiene. Thus, this review sheds light on the prevalent use of Neural Networks in toxicity prediction, thereby serving as a valuable resource for researchers and practitioners across these multifaceted domains that could be extended to other fields in future research.

Published: October 2023

In this paper, we investigate the mixed solution of reduced biquaternion matrix equation $ \sum\limits_{i = 1}^nA_iX_iB_i = E $ with sub-matrix constraints. With the help of $ \mathcal{L_C} $-representation and the properties of vector operator based on semi-tensor product of reduced biquaternion matrices, the reduced biquaternion matrix equation (1.1) can be transformed into linear equations. A systematic method, $ \mathcal{GH} $-representation, is proposed to decrease the number of variables of a special unknown reduced biquaternion matrix and applied to solve the least squares problem of linear equations. Meanwhile, we give the necessary and sufficient conditions for the compatibility of reduced biquaternion matrix equation (1.1) under sub-matrix constraints. Numerical examples are given to demonstrate the results. The method proposed in this paper is applied to color image restoration.
Exploring optical soliton solutions of the time fractional q-deformed Sinh-Gordon equation using a semi-analytic method

Published: October 2023

The $ \mathsf{q} $-deformed Sinh-Gordon equation extends the classical Sinh-Gordon equation by incorporating a deformation parameter $ \mathsf{q} $. It provides a framework for studying nonlinear phenomena and soliton dynamics in the presence of quantum deformations, leading to intriguing mathematical structures and potential applications in diverse areas of physics. In this work, we imply the homotopy analysis method, to obtain approximate solutions for the proposed equation, the error estimated from the obtained solutions reflects the efficiency of the solving method. The solutions were presented in the form of 2D and 3D graphics. The graphics clarify the impact of a set of parameters on the solution, including the deformation parameter $ \mathsf{q} $, as well as the effect of time and the fractional order derivative.

Published: October 2023

This study aimed to develop a healthy blended oil with a balanced fatty acid ratio, as well as high thermal and oxidative stability. The blending of highly saturated Palm olein (PO) with polyunsaturated fatty acid-rich (PUFA) Perilla seed oil (PeO) in two different proportions, 70:30 (B1) and 80:20 (B2) v/v was studied. The physicochemical parameters, fatty acid composition, and oxidative stability of cold-pressed perilla seed oil (PeO), palm olein, and their blends were analyzed. The blends presented higher oxidative stability (6.5 h) with enhanced α-linolenic acid content (18%) than pure oils. The fatty acid ratio in both blend (B1- 1:1.4:1 and B2- 1.5:1.5:1) was found close to the WHO recommended ratio i.e., 1:1-5:1. The evaluation of the thermal stability of the blended oils revealed that PeO oxidized quickly during heating (Peroxide value-15.16 meq O2/kg); whereas thermal stability improved with blending (Peroxide value: B1-7.92 and B2- 7.69 meq O2/kg).

Published: October 2023

There is a contentious need for robust and rapid methodologies for maintaining the authenticity of foods. The aim of this study was to detect and quantify argan oil adulteration using Laser Induced Fluorescence (LIF) spectroscopy coupled with chemometric methods. Principal Component Analysis (PCA) and Partial Least Squares Regression (PLSR) were used to assess argan oil authenticity; PCA was used to classify samples according to their quality and the PLS model to determine the amount of adulterants in pure argan oil. The correlation coefficient of the obtained model was about 0.99, with Root Mean Square Error of Prediction (RMSEP) and Standard Error of Prediction (SEP) of 2%. This study demonstrated the feasibility of LIF spectroscopy combined with chemometric tools to identify adulterants in pure argan oil from a percentage of adulteration, of 0.35 % without the need to destruct samples.

Published: October 2023

Olive oil is the most popular product derived from Olea europaea L. due to its organoleptic characteristics and its beneficial effects on human health. Nowadays, there is a growing interest in olive oil enrichment with medicinal plants. In this regard, Artemisia absinthium L. is an edible source of antioxidants. The aim of the present study was to improve the oxidative stability and the nutritional value of Organic Tunisian Chetoui Olive oil by its enrichment with the phenolic compounds in Artemisia absinthium. The enrichment carried out by maceration and ultrasound-assisted extraction did not affect the organic criteria of olive oil. The comparative study, performed during one year of storage, showed that ultrasound-assisted extraction led to the lowest final peroxide and extinction coefficient values. At the end of storage, this method increased oleic acid content and biophenol contents. Furthermore, the anti-radical activities of enriched samples were higher than the control.

Authors: Wang S. , Wu W.
Published: October 2023

A green and efficient method for producing high quality oil and defatted meal is in high demand, which has promoted the development of a hydration method for extracting oils from hem seed kernels. The hydration method optimized in this study recovered > 96% oil, which was further proved by infrared spectra, and extracted > 91% tocopherols, vitamin A, carotenoids, coenzyme Q10, phytosterols and squalene into the oil phase; while only small portions of flavonoids, other phenolic compounds and free fatty acids were extracted. The defatted meal was rich in water-soluble vitamins (including thiamin, riboflavin, niacin, pyridoxine, folate and vitamin C), proteins, dietary carbohydrates and phospholipids. The hydration method produced oils with lower AV or PV compared to solvent extraction, supercritical CO2 and cold-pressing methods and a defatted meal with a protein content (52.69%) which was significantly higher than that obtained by supercritical CO2 and cold-pressing methods. The hydration method is a type of green technology for sustainablly processing hempseeds.
An Effective Intrusion Detection in Mobile Ad-hoc Network Using Deep Belief Networks and Long Short-Term Memory
Authors: Hanafi Abdulfatai Shola , Saheed Yakub Kayode , Arowolo Micheal Olaolu
Published: October 2023

A Mobile Ad-hoc Network (MANET) is a self-organizing collection of mobile devices communicating in a distributed fashion across numerous hops. MANETs are an appealing technology for many applications, including rescue operations, environmental monitoring, tactical operations, and so on, because they let people communicate without the usage of permanent infrastructure. This flexibility, however, creates additional security vulnerabilities. Because of its benefits and expanding demand, MANETs have attracted a lot of interest from the scientific community. They do, however, seem to be more vulnerable to numerous attacks that wreak havoc on their performance than any network. Traditional cryptography techniques cannot entirely defend MANETs in terms of fresh attacks and vulnerabilities due to the distributed architecture of MANETs; however, these issues can be overcome by using machine learning approaches-based intrusion detection systems (IDS). IDS, typically screening system processes and identifying intrusions, are commonly employed to supplement existing security methods because preventative techniques are never enough. Because MANETs are continually evolving, their highly limited nodes, and the lack of central observation stations, intrusion detection is a complex and tough process. Conventional IDSs are difficult to apply to them. Existing methodologies must be updated for MANETs or new approaches must be created. This paper aims to present a novel concept founded on deep belief networks (DBN) and long shortterm memory (LSTM) for MANET attack detection. The experimental analysis was performed on the probe, root to local, user to root, and denial of service (DoS) attacks. In the first phase of this paper, particle swarm optimization was used for feature selection, and subsequently, the DBN and LSTM were used for the classification of attacks in the MANET. The experimental results gave an accuracy reaching 99.46%, a sensitivity of 99.52%, and a recall of 99.52% for DBN and LSTM accuracy reaching 99.75%, a sensitivity of 99.79%, and a recall of 99.79%.

L’arrêt de la Cour africaine des droits de l’homme et des peuples rendu le 1er décembre 2022 dans l’affaire Tike Mwambipile et Equality Now contre République-unie de Tanzanie illustre la problématique de l’articulation entre les instruments juridiques internationaux des droits de l’homme et celle de la coexistence de leurs organes de protection. Il soulève en particulier le problème de la compétence concurrente en ce qui concerne les allégations de violations des droits de l’homme couvertes à la fois par la Charte africaine des droits de l’homme et des peuples et par la Charte africaine des droits et du bien-être de l’enfant. L’interprétation que la Cour africaine fait de la règle non bis in idem contenue dans l’article 56(7) de la Charte africaine des droits de l’homme et des peuples élargit considérablement la portée de l’interdiction de la duplication de procédure. Elle lui permet d’éviter d’exercer une compétence concurrente avec d’autres juridictions et quasi-juridictions internationales des droits de l’homme, en l’occurrence le Comité africain d’experts des droits et du bien-être de l’enfant.

There are numerous methods to enhance the quality of cellulose for efficient and sustainable fuel production, the acid and alkaline pretreatment methods have become increasingly popular due to their accessibility and affordability. These methods are typically used to eliminate lignin, disrupt the cellulose crystalline structure, and reduce its rigidity. This study focuses on the use of pretreatment with four different types of acids (Hydrochloric Acid, Phosphoric Acid, Acetic Acid, and Sulfuric Acid) and four types of alkaline (Calcium Hydroxide, Sodium hydroxide, Potassium Hydroxide, and Ammonium Hydroxide) were used to soak the used tea waste powder as a raw material under microwave-assisted pretreatment. The effectiveness of acid and alkaline pretreatment methods under microwave heating on used tea waste powder was evaluated through infrared analysis. The experiments were conducted at varying microwave temperatures (100–200 °C), reaction times (2–7 min), and with a 2 g doses of used tea waste powder in 100 mL of diluted acid, and 5% of alkaline solution. The weight loss of liquid and solid samples after acid and alkaline pretreatment under the aid of microwave pretreatment were calculated. FTIR analysis results showed a significant improvement in the characteristics of the treated samples compared to the untreated used tea waste powder.

Published: October 2023

Platelet-rich plasma (PRP) is gaining more and more attention in regenerative medicine as an innovative and efficient therapeutic approach. The regenerative properties of PRP rely on the numerous bioactive molecules released by the platelets: growth factors are involved in proliferation and differentiation of endothelial cells and fibroblasts, angiogenesis and extracellular matrix formation, while cytokines are mainly involved in immune cell recruitment and inflammation modulation. Attempts are ongoing to improve the therapeutic potential of PRP by combining it with agents able to promote regenerative processes. Two interesting candidates are ozone, administered at low doses as gaseous oxygen-ozone mixtures, and procaine. In the present study, we investigated the effects induced on platelets by the in vitro treatment of PRP with ozone or procaine, or both. We combined transmission electron microscopy to obtain information on platelet modifications and bioanalytical assays to quantify the secreted factors. The results demonstrate that, although platelets were already activated by the procedure to prepare PRP, both ozone and procaine induced differential morpho-functional modifications in platelets resulting in an increased release of factors. In detail, ozone induced an increase in surface protrusions and open canalicular system dilation suggestive of a marked α-granule release, while procaine caused a decrease in surface protrusions and open canalicular system dilation but a remarkable increase in microvesicle release suggestive of high secretory activity. Consistently, nine of the thirteen platelet-derived factors analysed in the PRP serum significantly increased after treatment with ozone and/or procaine. Therefore, ozone and procaine proved to have a remarkable stimulating potential without causing any damage to platelets, probably because they act through physiological, although different, secretory pathways.
The impact of openness to experience personality trait on attitudes of medical students toward euthanasia: the moderating role of spiritual intelligence
Authors: Khosravi Mohsen
Published: October 2023

Euthanasia is the most important ethical challenges in the entire field of medicine. Various factors may influence the medical students’ attitudes toward euthanasia, including personal beliefs, values, and personality traits. This research aimed at examining spiritual intelligence as a moderator of the relationship between openness to experience and attitude toward euthanasia. In this cross-sectional study, a total of 219 medical students (85 men and 134 women) in Zahedan, Iran, in 2022, were selected by convenience sampling method and evaluated using the socio-demographic information form (including age, gender, and medical education level), Spiritual Intelligence Self-Report Inventory, 24-item Brief HEXACO Inventory, and Euthanasia Attitude Scale, followed by using SPSS v25 for data analysis. The study results showed that openness to experience positively and spiritual intelligence negatively associated with attitude toward euthanasia. Also, the regression analysis revealed that spiritual intelligence had a moderating role in the relationship between openness to experience and attitude toward euthanasia. It seems that paying attention to personality differences and spiritual intelligence training among medical students can play an important role in changing their attitudes toward euthanasia.
A uniform characterisation of the varieties of the second row of the Freudenthal–Tits magic square over arbitrary fields

Published: October 2023

We characterise the projective varieties related to the second row of the Freudenthal–Tits magic square, for both the split and the non-split form, using a common, simple and short geometric axiom system. A special case of our result simultaneously captures the analogues over arbitrary fields of the Severi varieties (comprising the

27

-dimensional

\mathrm{E_6}

module and some of its subvarieties), as well as the Veronese representations of projective planes over composition division algebras (most notably the Cayley plane). It is the culmination of almost four decades of work since the original 1984 result by Mazzocca and Melone who characterised the quadric Veronese variety over a finite field of odd order. The latter result is a finite counterpart to the characterisation of the complex quadric Veronese surface by Severi from 1901.
Symmetry Breaking Operators for Strongly Spherical Reductive Pairs
Authors: Frahm Jan
Published: October 2023

A real reductive pair

(G,H)

is called strongly spherical if the homogeneous space

(G\times H)/\operatorname{diag}(H)

is real spherical. This geometric condition is equivalent to the representation-theoretic property that

\dim \operatorname{Hom}_H(\pi|_H,\tau)<\infty

for all smooth admissible representations

\pi

of

G

and

\tau

of

H

. In this paper we explicitly construct for all strongly spherical pairs

(G,H)

intertwining operators in

\operatorname{Hom}_H(\pi|_H,\tau)

for

\pi

and

\tau

spherical principal series representations of

G

and

H

. These so-called
symmetry breaking operators
depend holomorphically on the induction parameters and we further show that they generically span the space

\operatorname{Hom}_H(\pi|_H,\tau)

. In the special case of multiplicity one pairs we extend our construction to vector-valued principal series representations and obtain generic formulas for the multiplicities between arbitrary principal series. As an application, we prove an early version of the Gross–Prasad conjecture for complex orthogonal groups, and also provide lower bounds for the dimension of the space of Shintani functions.

C_0

-semigroups on a Banach lattice, which is assumed to be a Riesz subspace of a

\sigma

-Dedekind complete Banach lattice. Typical examples include the space of all bounded uniformly continuous functions and the space of all continuous functions vanishing at infinity. We show that the domain of the classical generator of a convex semigroup is typically not invariant. Therefore, we propose alternative versions for the domain, such as the monotone domain and the Lipschitz set, for which we prove invariance under the semigroup. As a main result, we obtain the uniqueness of the semigroup in terms of an extended version of the generator. The results are illustrated with several examples related to Hamilton–Jacobi–Bellman equations, including nonlinear versions of the shift semigroup and the heat equation. In particular, we determine their symmetric Lipschitz sets, which are invariant and allow us to define the generators in a weak sense.
Enhanced Nearby and Vanishing Cycles in Dimension One and Fourier Transform
Authors: D’Agnolo Andrea , Kashiwara Masaki
Published: October 2023

Enhanced ind-sheaves provide a suitable framework for the irregular Riemann–Hilbert correspondence. In this paper, we give some precision on nearby and vanishing cycles for enhanced perverse objects in dimension one. As an application, we give a topological proof of the following fact. Let

\mathcal{M}

be a holonomic algebraic

\mathcal{D}

-module on the affine line, and denote by

{^{\mathsf{L}}}\mathcal{M}

its Fourier–Laplace transform. For a point

a

on the affine line, denote by

\ell_a

the corresponding linear function on the dual affine line. Then the vanishing cycles of

\mathcal{M}

at

a

are isomorphic to the graded component of degree

\ell_a

of the Stokes filtration of

{^{\mathsf{L}}}\mathcal{M}

at infinity.

We show the existence of group-theoretic sections of certain
geometrically pro-nilpotent by abelian
arithmetic fundamental groups of hyperbolic curves over

p

-adic local fields which are
non-geometric
, i.e., which do not arise from rational points. Among these quotients is the
geometrically metabelian
arithmetic fundamental group.

Let

f

be an automorphism of a complex Enriques surface

Y

and let

p_f

denote the characteristic polynomial of the isometry

f^*

of the numerical Néron–Severi lattice of

Y

induced by

f

. We combine a modification of McMullen’s method with Borcherds’ method to prove that the modulo-

reduction

(p_f(x) \bmod 2)

is a product of modulo-

2

reductions of (some of) the five cyclotomic polynomials

\Phi_m

, where

m \leq 9

and

m

is odd. We study Enriques surfaces that realizevmodulo-

reductions of

\Phi_7

,

\Phi_9

and show that each of the five polynomials

(\Phi_m(x) \bmod 2)

is a factor of the modulo-

(p_f(x) \bmod 2)

for a complex Enriques surface.
Quasianalytic Functionals and Ultradistributions as Boundary Values of Harmonic Functions
Authors: Debrouwere Andreas , Vindas Jasson
Published: October 2023

We study boundary values of harmonic functions in spaces of quasianalytic functionals and spaces of ultradistributions of non-quasianalytic type. As an application, we provide a new approach to Hörmander’s support theorem for quasianalytic functionals. Our main technical tool is a description of ultradifferentiable functions by almost harmonic functions, a concept that we introduce in this article. We work in the setting of ultradifferentiable classes defined via weight matrices. In particular, our results simultaneously apply to the two standard classes defined via weight sequences and via weight functions.

OBJECTIVES: Proteinuria is widely used to predict cardiovascular risk. However, there is insufficient evidence to predict how changes in proteinuria may affect the incidence of cardiovascular disease.METHODS: The study included 265,236 Korean adults who underwent health checkups in 2003-2004 and 2007-2008. They were categorized into 4 groups based on changes in proteinuria (negative: negative → negative; resolved: proteinuria ≥1+ → negative; incident: negative → proteinuria ≥1+; persistent: proteinuria ≥1+ → proteinuria ≥1+). We conducted 6 years of follow-up to identify the risks of developing ischemic heart disease (IHD), acute myocardial infarction (AMI), and angina pectoris according to changes in proteinuria. A multivariate Cox proportional-hazards model was used to calculate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for incident IHD, AMI, and angina pectoris.RESULTS: The IHD risk (expressed as HR [95% CI]) was the highest for persistent proteinuria, followed in descending order by incident and resolved proteinuria, compared with negative proteinuria (negative: reference, resolved: 1.211 [95% CI, 1.104 to 1.329], incident: 1.288 [95% CI, 1.184 to 1.400], and persistent: 1.578 [95% CI, 1.324 to 1.881]). The same pattern was associated with AMI (negative: reference, resolved: 1.401 [95% CI, 1.048 to 1.872], incident: 1.606 [95% CI, 1.268 to 2.035], and persistent: 2.069 [95% CI, 1.281 to 3.342]) and angina pectoris (negative: reference, resolved: 1.184 [95% CI, 1.065 to 1.316], incident: 1.275 [95% CI, 1.160 to 1.401], and persistent: 1.554 [95% CI, 1.272 to 1.899]).CONCLUSIONS: Experiencing proteinuria increased the risks of IHD, AMI, and angina pectoris even after proteinuria resolved.
Protección y gestión holística de bosques de Nothofagus en la Península de Brunswick, Chile

Published: October 2023

El objetivo de este estudio fue evaluar el impacto del uso histórico del bosque costero de Nothofagus, sobre su valor natural y cultural a lo largo de la costa oriental de la Península de Brunswick, Chile. Para ello se revisaron archivos históricos del territorio y se evaluaron los cambios de estructura forestal a lo largo de transectos desde la costa hacia el interior, en tres sitios distintos. En cada parcela se midieron los diámetros y el área basal y se tomaron muestras dendrocronológicas de los árboles. Además, se midieron los árboles muertos y se registraron los signos de intervención histórica. Los resultados indican que estos bosques fueron explotados mediante tala y que existen diferencias significativas entre las parcelas taladas y las no taladas, que entre los sitios. Las variables que difirieron fueron los diámetros, la edad y las áreas basales de los árboles muertos y D. winteri. En algunos casos fue posible vincular las diferencias entre las parcelas de un sitio con los usos históricos. El tiempo transcurrido y la limitada extensión espacial de la explotación forestal presentan una oportunidad real para la conservación y restauración de esos bosques con altos valores naturales y culturales.
Incorporation of Green Infrastructure on Road Tunnel Ventilation Stacks: Potential Ambient Air Quality Improvement

Published: October 2023

Vehicular tunnels are an important part of transportation infrastructure, though there are concerns about air quality due to the concentrated release of polluted air at roadway portals and tunnel ventilation stacks. Urban green infrastructure offers opportunities as a nature-based solution to mitigate urban particulate matter pollution. Green walls have advantages over other types of urban green infrastructure, since they can be potentially applied to large vertical surfaces available within cities and since they can be retrofitted onto already built structures. However, uptake of green wall technology has been limited on infrastructure projects, let alone the integration of green walls and roadway portals and tunnel ventilation stacks, which represents the first of its type worldwide. Therefore, this study aims to describe the integration of green wall technologies and a tunnel ventilation facility, and models the potential ambient air quality improvement the green wall plants have through PM2.5 dry deposition. It was found that the project would increase ambient PM2.5 to a concentration of 13.6 ug/m3, and that the green walls would have the capacity to remove significant amounts of PM2.5, from not only the ambient air pollutant increase as a result of the ventilation outlets, but also the background and surrounding surface road contributions. Differences in the rate of pollutant removed per stack by the green walls were attributed mostly to the varying ratios of plants installed. The findings indicate the air quality benefits of green wall integration on major infrastructure projects, which will assist in the overall sustainability appraisal of large infrastructure projects which need to balance the needs of population growth with environmental and human health.

Esse estudo objetivou analisar como estudantes dos Anos Finais do Ensino Fundamental compreendem o lugar do corpo na escola, a partir da experiência da Educação Física escolar mediada pelas tecnologias digitais, no período da pandemia de COVID-19. Esse estudo justifica-se pela necessidade do olhar para o corpo no retorno às aulas presenciais. Trata-se de uma pesquisa com abordagem qualitativa e descritiva, realizada em duas escolas da rede municipal de ensino de um município do Vale do Taquari/RS. Participaram 16 estudantes dos anos finais do Ensino Fundamental, oito de uma turma do 6º Ano e oito de uma turma do 9º Ano, e duas professoras de Educação Física. As informações foram produzidas por meio de observações de aulas registradas em diário de campo, grupos de discussão com alunos e entrevista semiestruturada com professores. A metodologia utilizada foi a Análise Textual Discursiva. Em ambas as turmas, houve o entendimento de que a essência da Educação Física é movimentar-se e, por essa razão, não reivindicam o uso das tecnologias digitais nas aulas presenciais. Além disso, constata-se que a Educação Física escolar é um lugar onde os alunos sentem-se corpo e convivem com os corpos dos colegas. Por fim, conclui-se que as tecnologias digitais foram fundamentais para a continuidade do ensino no período de pandemia de COVID-19, mas, no retorno às aulas presenciais, os estudantes querem conhecer o mundo pelo próprio corpo, por meio da vivência das diferentes práticas corporais e na interação com professores e colegas de aula.
