Aims. We aim to investigate the infrared excess of 45 Milky Way (MW) Cepheids combining different observables in order to constrain the presence of circumstellar envelopes (CSEs).
Methods. We used the SpectroPhoto-Interferometry of Pulsating Stars (SPIPS) algorithm, a robust implementation of the parallax-of-pulsation method that combines photometry, angular diameter, stellar effective temperature, and radial velocity measurements in a global modelling of the pulsation of the Cepheid. We obtained new photometric measurements at mid-infrared (mid-IR) with the VISIR instrument at the Very Large Telescope complemented with data gathered from the literature. We then compared the mean magnitude of the Cepheids from 0.5 μm to 70 μm with stellar atmosphere models to infer the IR excess, which we attribute to the presence of a circumstellar envelope.
Results. We report that at least 29% of the Cepheids of our sample have a detected IR excess (> 3σ). We estimated a mean excess of 0.08 ± 0.04 mag at 2.2 μm and 0.13 ± 0.06 mag at 10 μm. Other Cepheids possibly also have IR excess, but they were rejected due to their low detection level compared to a single-star model. We do not see any correlation between the IR excess and the pulsation period as previously suspected for MW Cepheids, but a rather constant trend at a given wavelength. We also do not find any correlation between the CO absorption and the presence of a CSE, but rather with the stellar effective temperature, which confirms that the CO features previously reported are mostly photospheric. No bias caused by the presence of the circumstellar material is detected on the average distance estimates from a SPIPS analysis with a fitted colour excess. We also do not find correlation between the presence of IR excess and the evolution stage of the Cepheids.
Conclusions. We report a fraction of 29% of Cepheids with an IR excess likely produced by the circumstellar envelope surrounding the stars. Longer period Cepheids do not exhibit greater excess than short periods as previously suspected from observations and theoretical dusty-wind models. Other mechanisms such as free-free emission, among others, may be at the origin of the formation of the CSEs. We also show that not fitting the colour excess leads to a bias on the distance estimates in our Galaxy.

The article presents the study results of changes in flow hydraulic parameters and morphometric elements of the river in the area of the main dam intake structure. A model for studying the direction of flow and other parameters of the flow in the area of the main structure for obtaining water from the Amudarya without a dam has been developed. A functional graph of the depth dependence of the expenditure on the study object was obtained. Graphs of the functional dependence of the diurnal cross-section of the riverbed on the flow depth and the variation of the flow velocity depending on the flow depth were constructed.
The direction and distribution of the flow in the area of the main dam intake structure were studied.

The article presents the main results of substantiating the materials used when conducting experimental studies of channel processes in a river, the channel of which is composed of easily eroded soils. It is substantiated that the Amudarya sand cannot be modeled on a geometric scale since the model deposits are too small (powder) and lose the property of loose bodies. In such cases, a material with a decrease in specific gravity without a decrease in diameter is used as a substitute for sand. Since the sediment diameter cannot be reduced, the actual scale of the model remains distorted. It is indicated that the sediment diameter cannot be reduced, then in fact, the scale of the model remains distorted. Therefore, when the bottom of a river bank is made of sand that does not lend itself to geometric modeling, regardless of the change in the specific gravity of the natural material, to ensure the mobility of the sand on the model, it is necessary to distort the vertical scale.
Distortion of scales is also necessary because when using in laboratory conditions the same sand that formed the bed of the river, at any depth with a low velocity, the model observes bottom resistances to the flow of the flow compared with nature. The vertical and plan scales of modeling were calculated, respectively, equal to 50 and 57. According to the results of the calculations, the value of the coefficient of mobility of bottom sediments was established, which was equal to 1.

SummaryStudien belegen, dass die Ernährung direkt mit dem Gesundheitszustand des oralen Systems in Verbindung steht. Bei oralen Beschwerden resultieren häufig eine eingeschränkte Kaufähigkeit sowie ungünstige Veränderungen der Nahrungsmittelauswahl mit beispielsweise verringertem Obst- und Gemüseverzehr.Für die Mundgesundheit wichtige Nährstoffe wie Vitamin C, Kalzium, Vitamin B12, Folsäure und Eisen werden dann oft nur unzureichend aufgenommen.Die Nahrungsmittelauswahl sollte sich an der vollwertigen Mischkost orientieren, mit hohem Obst- und Gemüseanteil. Mit den entsprechenden Lebensmitteln können typische Probleme im Alter wie Mundtrockenheit und entzündliche Schleimhautveränderungen positiv beeinflusst werden. Mit der geeigneten Zubereitung lassen sich Hürden z.B. bei eingeschränkter Kaufähigkeit überwinden.
Fractura de fémur proximal (31-A3.2) asociada al uso de tenofovir en paciente VIH + : Reporte de caso
Authors: Ruiz Pia Franz , Avilez Marco Poblete 
Published: June 2021

ResumenPresentamos el primer reporte de caso en paciente adulto con virus de la inmunodeficiencia humana (VIH + ) con fractura por fragilidad en fémur proximal asociada al uso de terapia antirretroviral (TARV) con fumarato de disoproxilo de tenofovir (FDT) en Chile. Actualmente, los pacientes diagnosticados con VIH inician tratamiento precoz con TARV, lo que implica mayor cantidad de años de exposición a los fármacos de la terapia. El tiempo de exposición acumulado al FDT se ha asociado a disminución de la densidad mineral ósea y falla renal progresiva, pudiendo el paciente desarrollar síndrome de Fanconi adquirido y osteomalacia, con riesgo aumentado de fractura. Presentamos el caso de un hombre de 44 años, VIH + , evaluado en urgencia tras caída a nivel que resultó en fractura patológica del fémur proximal. Los exámenes de ingreso destacaron hipocalemia, hipocalcemia, hipofosfatemia e hipovitaminosis D. Se realizó manejo multidisciplinario, con suspensión del FDT, un cambio en la TARV, y suplementación con calcio y carga de vitamina D. Se realizó reducción cerrada y fijación con clavo cefalomedular largo, que evolucionó favorablemente con rehabilitación motora precoz; el paciente recuperó su funcionalidad previa, y se observó consolidación ósea a las 12 semanas. La aparición de dolor osteomuscular en pacientes VIH+ en TARV debe levantar alta sospecha clínica de efecto adverso a medicamiento; el seguimiento de estos pacientes debe incluir el control seriado de la función renal y de los niveles séricos de calcio y fósforo. La búsqueda y sospecha de estas complicaciones permitiría una intervención precoz, mejorando la condición de los pacientes y previniendo fracturas patológicas.

Published: May 2021

Abstract
Introduction Fosfomycin and nitrofurantoin are increasingly being prescribed in outpatients for the oral treatment of urinary tract infection (UTI). Although ample literature is available on the in vitro sensitivity pattern of fosfomycin and nitrofurantoin in UTI cases, clinical data are scant.
Methodology Voided midstream urine, collected from patients ≥ 16 years of age of both genders with suspected sign and symptoms, was plated on cystine lactose electrolyte-deficient agar. Uropathogen was defined as an organism known to be associated with the signs and symptoms of UTI with > 105 colony forming units/mL of urine. Antimicrobial susceptibility testing was determined by Kirby-Bauer disc diffusion method. Further, for fosfomycin, agar dilution method was also performed.
Results A total of 143 patients, 47 treated with fosfomycin and 96 with nitrofurantoin, were followed for clinical outcome. The most common isolated uropathogen was Escherichia
coli. In vitro susceptibility rate of uropathogens against fosfomycin and nitrofurantoin was 99.3% and 81.2%, respectively. Overall, the clinical cure rate with fosfomycin and nitrofurantoin treatment groups was 80.85% and 90.06% respectively (not statistically significant).
Conclusion Fosfomycin and nitrofurantoin showed good in vitro activity against uropathogens from lower UTI and can be used for empirical therapy in our area. Multiple confounding factors may have contributed to the discrepancy between in vitro susceptibility and clinical cure, which needs to be studied further.

Abstract

Eragrostis pilosa is an annual grass native to Eurasia and Africa that has become naturalized in many other tropical and temperate regions of the world. It is a common weed in disturbed areas such as roadsides and crop fields. It is invasive in a number of Pacific Islands, the Philippines, Australia, and North America but no further information is available about its impacts or invasiveness in natural or semi-natural habitats in its non-native range.
Grapholita molesta (Oriental fruit moth).
Authors: Il'ichev Alex 
Published: May 2021

Abstract

G. molesta is a serious pest of economic importance of commercial stone and pome fruits around the world. G. molesta damages peaches, nectarines, plums, cherries, apricots, apples, pears, quinces and nashi (Asian pears) and can also attack and cause economic damage on other commercial fruits. In severe attacks, young trees can suffer distortion of growing shoots and stems, which makes pruning, training and shaping the tree canopy difficult, particularly for close-planting industrial systems such as Tatura trellis. One larva can damage many shoots by tunnelling deep into young shoot tips. Larvae move to feed on the green fruits usually after shoots mature and harden. One larva can damage many fruits, particularly when fruits are located close to each other.
Opuntia stricta (erect prickly pear).
Authors: Pasiecznik Nick , Rojas-Sandoval Julissa 
Published: May 2021

Abstract

Opuntia stricta is a cactus species native to the Americas that has been introduced worldwide as a popular ornamental. This species escaped from cultivation and has become invasive in many countries across Africa and Australia, but also more recently in the Mediterranean basin. Large and serious invasions have been reported in Australia, South Africa, Namibia, Yemen, India, Sri Lanka, Madagascar and lately also Spain and some North African countries. It has also become naturalized in many other regions (primarily in Africa and Asia) where it has not yet been recorded as a pest. In South Africa and Namibia large infestations have been reported, mainly in dry savanna bushlands, while in Australia all states are invaded with widespread populations invading southeastern Queensland and northeastern New South Wales. Successful biological control programmes have, however, severely reduced the spread of this species in many areas where introduced, though there continues to be a risk of further introduction through the nursery trade.
Universalism doesn’t entail extensionalism
Authors: Loss Roberto 
Published: May 2021

Abstract
In the literature on mereology it is often accepted that mereological universalism entails extensionalism. More precisely, many accept that, if parthood is assumed to be a partial order (and, thus, the relevant theory of parthood is taken to be at least as strong as ‘core mereology’), the thesis that every plurality of entities has a mereological fusion entails the thesis that different composite entities have different proper parts. Central to this idea is the principle known as ‘Weak Supplementation’ which many take to impose an important constraint on the relation of proper parthood. In this paper I argue that this claim is false as the principle that I will call ‘Minimal Supplementation’ appears to be capable of doing all the work done by Weak Supplementation but without entailing extensionalism if conjoined with universalism and core mereology.
Species cohesion of an extremophyte (Carex angustisquama, Cyperaceae) in solfatara fields maintained under interspecific natural hybridization

Published: May 2021

Abstract

Background and Aims
Hybridization is the main driver of plant diversification, and gene flow via hybridization has multifaceted effects on plant evolution. Carex angustisquama is an extremophyte that grows on soils heavily acidified by volcanism. Despite its habitat distinct from that of other species, this species is known to form interspecific hybrids, implying interspecific gene flow. It is crucial to verify the extent and direction of interspecific gene flow between C. angustisquama and closely related species to understand the evolutionary process of an extremophyte in solfatara fields.

Methods
In this study, expressed sequence tag–simple sequence repeat markers were utilized to infer the extent and direction of interspecific gene flow between C. angustisquama and closely related species.

Key Results
Bayesian clustering and simulation analyses revealed that all individuals of the three hybrid species were classified into the first hybrid generation or first backcross to C. angustisquama; therefore, current interspecific gene flow is limited. Moreover, in the Bayesian inference of historical gene flow based on multispecies samples, the model that assumed no interspecific gene flow was the most strongly supported across all species pairs, including phylogenetically close but ecologically distinctive species pairs.

Conclusions
Our results revealed that interspecific gene flow between C. angustisquama and its related species has been limited both currently and historically. Moreover, our results of Bayesian inference of historical gene flow indicated that extrinsic, rather than intrinsic, factors probably act as isolating barriers between Carex species, with hybrid breakdown via microhabitat segregation being the probable potential barrier. Overall, our findings provide insights into the evolutionary process of an extremophyte in solfatara fields and offer an important example of the mechanisms of diversification of the speciose genus Carex.
Binding non-signatories to arbitrate—the United States approach
Authors: Mišović Andrijana 
Published: June 2021

Abstract
Parties’ consent to the arbitration is the basis for tribunal’s authority to decide the case and, as such, is of fundamental importance in any arbitration proceedings. Commercial reality, however, often requires from the so called ‘non-signatories’ of the contract containing an arbitration clause to participate in performance of such contract. Being sensitive to such commercial concerns, the US courts have developed different domestic theories for binding the non-signatories. Recent ruling of the US Supreme Court holds that such domestic theories are also applicable in cases governed by Chapter 2 of the Federal Arbitration Act (incorporating New York Convention). However, the Supreme Court did not resolve the question which law should be applied to the issue of binding the non-signatories. Although US courts might be more inclined to apply federal principles to this issue, this is not the only possible solution based on the current SCOTUS case-law. The US court could also resort to the choice of law analysis and apply appropriate (foreign) state principles for binding the non-signatories. However, different states clearly have different views of the issue of binding the non-signatories, as this article briefly outlines. Thus, the same factual pattern might lead to completely different results.
Circ_0091702 relieves lipopolysaccharide (LPS)-induced cell injury by regulating the miR-182/PDE7A axis in sepsis
Authors: Zhang Xinliang , Dong Shimin 
Published: June 2021

ABSTRACT
Circular RNA plays an important role in the progression of sepsis. Circ_0091702 has been found to be an important regulator of sepsis progression, so its role and mechanism in sepsis progression deserve to be further explored. Lipopolysaccharide (LPS) could suppress cell viability, while enhance cell apoptosis and inflammation to induce cell injury. Circ_0091702 was downregulated in LPS-induced HK2 cells, and its overexpression alleviated LPS-induced cell injury. MiR-182 could be sponged by circ_0091702. Moreover, miR-182 inhibitor could relieve LPS-induced cell injury, and its overexpression also reversed the inhibition of circ_0091702 on LPS-induced cell injury. PDE7A was a target of miR-182, and its expression was reduced in LPS-induced HK2 cells. Additionally, silencing of PDE7A reversed the suppressive effect of circ_0091702 on LPS-induced cell injury. Our data suggested that circ_0091702 sponged miR-182 to regulate PDE7A, thereby alleviating LPS-induced cell injury in sepsis.

Abstract
Moderate or severe burns are potentially devastating injuries that can even cause death, and many of them occur every year. Infection prevention, anti-inflammation, pain management and administration of growth factors play key roles in the treatment of burn wounds. Novel therapeutic strategies under development, such as nanotherapeutics, are promising prospects for burn wound treatment. Nanotherapeutics, including metallic and polymeric nanoformulations, have been extensively developed to manage various types of burns. Both human and animal studies have demonstrated that nanotherapeutics are biocompatible and effective in this application. Herein, we provide comprehensive knowledge of and an update on the progress of various nanoformulations for the treatment of burn wounds.
Altered Dynamic Information Flow through the Cortico-Basal Ganglia Pathways Mediates Parkinson’s Disease Symptoms
Authors: Chiken Satomi , Takada Masahiko , Nambu Atsushi 
Published: May 2021

Abstract
Parkinson’s disease (PD) is a progressive neurodegenerative disorder caused by dopamine deficiency. To elucidate network-level changes through the cortico-basal ganglia pathways in PD, we recorded neuronal activity in PD monkeys treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine. We applied electrical stimulation to the motor cortices and examined responses in the internal (GPi) and external (GPe) segments of the globus pallidus, the output and relay nuclei of the basal ganglia, respectively. In the normal state, cortical stimulation induced a triphasic response composed of early excitation, inhibition, and late excitation in the GPi and GPe. In the PD state, cortically evoked inhibition in the GPi mediated by the cortico-striato-GPi “direct” pathway was largely diminished, whereas late excitation in the GPe mediated by the cortico-striato-GPe-subthalamo (STN)-GPe pathway was elongated. l-DOPA treatment ameliorated PD signs, particularly akinesia/bradykinesia, and normalized cortically evoked responses in both the GPi and GPe. STN blockade by muscimol injection ameliorated the motor deficit and unmasked cortically evoked inhibition in the GPi. These results suggest that information flow through the direct pathway responsible for the initiation of movements is largely reduced in PD and fails to release movements, resulting in akinesia/bradykinesia. Restoration of the information flow through the direct pathway recovers execution of voluntary movements.
Joining Formal Concept Analysis to Feature Extraction for Data Pruning in Cloud of Things
Authors: Moulahi Tarek 
Published: May 2021

Abstract
The enormous increase in the number of Internet of Things data sources (sensors, personal devices and embedded systems) has given rise to a huge amount of unnecessary and redundant data being sent to the cloud. This makes the task of processing and storing this volume of information a very hard one. Therefore, data pre-processing and filtering closer to data sources, such as in fog computing, is necessary. In particular, data reduction in the fog nodes may play a significant role in preventing the dramatic decrease in the Cloud of Things performance, especially in energy consumption, storage space, bandwidth and throughput. However, existing solutions are still lacking, considering they do not achieve the optimal data reduction performance especially in terms of delay and accuracy. In this article, we introduce an approach aiming to eliminate useless and redundant data captured by things basing on some intelligent information extraction techniques. We also evaluate the performance of the proposed solution on a real data set sample to demonstrate that it achieves a good features reduction.
CARAF: Crypto Agility Risk Assessment Framework
Authors: Ma Chujiao , Colon Luis , Dera Joe , Rashidi Bahman , Garg Vaibhav 
Published: May 2021

AbstractCrypto agility refers to the ability of an entity to replace existing crypto primitives, algorithms, or protocols with a new alternative quickly, inexpensively, with no or acceptable risk exposure. These changes may be driven by regulatory action, advances in computing, or newly discovered vulnerabilities. Yet everyday operational needs may put crypto agility considerations on the back burner when deploying technology, designing processes, or developing products/services. Consequently, changes are often performed in an ad hoc manner. Transition from one crypto solution to another can then take a long time and expose organizations to unnecessary security risk. This paper presents a framework to analyze and evaluate the risk that results from the lack of crypto agility. The proposed framework can be used by organizations to determine an appropriate mitigation strategy commensurate with their risk tolerance. We demonstrate the application of this framework with a case study of quantum computing and related threats to cryptography in the context of TLS for Internet of Things.
