Serial production of glued wooden structures (GWS) in Russia was organized in 1975. The structural system “TSNIISK” was created and improved since 1975. The feature of the system is the use of prefabricated GWS joints on glued rods in nodes and joints. They were applied in hundreds of large-span buildings: water parks, playpens, fertilizer terminals, sports facilities, which were designed in the Loadbearing wood structures of laboratory of TSNIISK named after V. A. Koucherenko. According to Federal Law FL No. 384 of 12/30/2009, the structures of these buildings are subject to field surveys and monitoring. The article presents systematized conclusions about the state of GWS based on the results of their examination. Characteristic defects of the GWS are delaminations along the adhesive seams and cracks along the wood. The main causes of delamination are operating conditions with low relative humidity, violations of bonding technology and design errors. The analysis of the state of the GWS allowed to form recommendations for safe operation and suggestions to the design standards.

THE INFLUENCE OF THE TRANSPORT FACTOR ON THE DEVELOPMENT OF URBAN AGGLOMERATIONS OF THE FERGANA VALLEY
Authors:   Lecturer Andijan State University Andijan, Uzbekistan, Isayev Akbarjon A. , . Abdurakhmonova Hilola L ,   Student Andijan State University Andijan, Uzbekistan
Published: March 2023

Population in Uzbekistan has long been connected with transport routes. Settlements were formed in areas where different roads passed from any settlements and, on the contrary, different transport routes passed. Such geographical features are especially evident in the regions of the Fergana Valley, where the population and transport networks are densely populated and land resources are limited. With the development of modern urban planning, the creation of new settlements, new cities and towns, the "appearance" of the regions is changing, and agglomerations are developing. The agglomerations of Fergana-Margulon, Namangan, Andijan, and Kokan, formed in the Fergana Valley, where the network of cities is dense in Uzbekistan, are sharply different from each other, despite being located in the same region. These differences were primarily influenced by the transport network and configuration of the region. The article mainly evaluates the impact of the transport factor on the development of the Andijan agglomeration, and comments on the formation of the Andijan-Asaka-Shakhrikhan-Poitug quadrangle of Andijan and its neighboring cities are put forward.

As the term fulfills tasks such as separating clear concepts in the fields of science, technology, art, and setting boundaries between them, it keeps its terminological character only within one terminological system. The difference in the definition of the term is often explained by the fact that the term can be more than one object of science at the same time. In the article, it is analyzed that the syntactic method of term creation dominates the derivation system of computer and internet terms in the Uzbek language.

Review question / Objective: For the sake of better apprehending the nexus between ferroptosis and chondrocytes in osteoarthritis (OA), proffering novel insights and opening-up new orientation for in-depth research in both pre-clinical and clinical settings, it is warranted to initiate one rigorous and robust systematic review (SR) based upon up-to-date in-vivo and in-vitro research advances on this topic. To the best our knowledge, no SRs concerning ferroptosis and chondrocytes in OA have been published thus far. Condition being studied: Osteoarthritis (OA) is the most common form of arthritis, which menaces 7% of the human population globally. With the aged tendency of population and higher rates of obesity, the incidence of OA is anticipated to proliferate, which will entail a mounting impact and major challenges for global health care and each country’s public health systems unavoidably. In virtue of the onset of OA is mighty knotty, its etiology and underlying molecular mechanisms have not been expressly expounded. However, the salient role that cartilage degeneration acts in the progression of OA has been widely acknowledged. Chondrocytes are consequential for the safeguard of cartilage homeostasis and the functional integrity of the articular cartilage. Once the homeostatic equilibrium of the extracellular matrix (ECM) synthesis and degradation is smashed, OA comes up.

The current rapid development of information technology has encouraged various sectors to shift from manual to digital, especially in the era of the pandemic. If the private sector is able to adapt to the massive use of digital technology, what about the government sector? The method in this study uses descriptive analysis of secondary data from various surveys and in-depth interviews at the Department of Information, Communication, and Statistics of Gorontalo Province. The digital ecosystem in the Gorontalo community is considered quite ready to enter the digital era. This can be seen from the coverage of digital infrastructure which has reached 93.3 percent of villages that have been served with an internet signal. A total of 72.68 percent of households have access to a cellular phone. In 2020, as many as 76. 68 percent of Gorontalo households have been accustomed to accessing the internet. On the other hand, the government has also begun to prepare digital public services, this can be seen from the Gorontalo Province SPBE index value in 2019 which has reached a value of 3.18 with a good predicate, although at the Regency / City level it is still categorized as sufficient a nd lacking. People who are getting easier to get information and are getting smarter, are starting to demand easy and quality public services. So that the government needs to be encouraged to digitize public services in order to be able to meet various demands in the current technological era. this can be seen from the Gorontalo Province SPBE index value in 2019 which has reached a value of 3.18 with a good predicate, although at the Regency / City level it is still categorized as sufficient and lacking.

The purpose of this study is to describe how the coordination of the Village Community Empowerment Institution (LPMD) in the implementation of development in Butu Village, Tilongkabila District, Bone Bolango Regency. The research method is descriptive with a qualitative approach. The results of the study indicate that the vertical coordination in Butu Village has not been maximized, this can be seen by the absence of togetherness between all parties in the institution, so that the problems that arise cannot be overcome together. Horizontal coordination between institutions in the village can be said to have not gone well, this can be seen from the lack of cooperation between the LPMD management and other institutions, so that planning and decision-making related to village development does not involve LPMD. LPMD is a partner of the Village government, it should know the duties and functions of each administrator. Every important decision making related to development in an area can be well coordinated between the village government and other institutions. The coordination carried out by the LPMD can assist the village government in implementing village development programs, but this has not gone well, because the Butu LPMD has not played an active role in the activities carried out by Butu Village.

Published: March 2023

This cross-sectional study enrolled 267 patients with metabolic risk factors and established non-alcoholic fatty liver disease in the prospective cohort. The performance of fibrosis-4 (FIB-4) score (≥1.3) to diagnose advanced fibrosis using transient elastography (liver stiffness measurement [LSM] ≥8 kPa) was analyzed. Comparing patients with type 2 diabetes (T2D, n=87) and without (n=180), not FIB-4, but LSM was significantly higher in T2D (P=0.026). The prevalence of advanced fibrosis was 17.2% in T2D and 12.8% in non-T2D. FIB-4 exhibited higher proportion of false negatives in T2D patients (10.9%) than those without (5.2%). The diagnostic performance of FIB-4 was suboptimal in T2D (area under curve [AUC], 0.653; 95% confidence interval [CI], 0.462 to 0.844) compared to that in non-T2D (AUC, 0.826; 95% CI, 0.724 to 0.927). In conclusion, patients with T2D might be beneficial to conduct transient elastography without screening to avoid missing advanced fibrosis.
Haciendo género con pizarras: aportes de la antropología simétrica al estudio del género en la investigación matemática
Authors: Valenzuela Fernando , Cortéz María Isabel , Sáez Mariel
Published: March 2023

En este artículo revisitamos el libro de Bruno Latour, Nunca fuimos modernos. Ensayos de antropología simétrica (NFM), publicado originalmente en 1991, en que el autor inició su exploración de las repercusiones del programa de una sociología de la traducción en la principal clave de autodescripción de la sociedad contemporánea en términos de modernidad. Nos centramos en el caso de la investigación matemática. Siendo el ejemplo más notorio de una disciplina pura, ella permite estudiar con mayor detenimiento las prácticas de purificación con que Latour caracteriza a los modernos. Proponemos que el análisis de la posición que ocupan las pizarras en los sitios de investigación matemática permite evaluar potencialidades y limitaciones del programa de antropología simétrica, tal como se presenta en NFM. Por un lado, su análisis revela las prácticas de traducción que sostiene el trabajo de investigación matemática y su demarcación respecto de otros dominios, que los recuentos purificados de la disciplina tienden a invisibilizar. Por otro lado, la participación de las pizarras en la reproducción del esquema de género da cuenta de una dimensión mayormente ignorada en este programa de investigación. En lugar de identificar en este último aspecto un punto ciego de la antropología simétrica, reconocemos en él un aporte que este programa de investigación aún puede hacer al estudio del género en la investigación matemática.
Estimation of the Full-sky Power Spectrum between Intermediate and Large Angular Scales from Partial-sky CMB Anisotropies Using an Artificial Neural Network
Authors: Pal Srikanta , Chanda Pallav , Saha Rajib
Published: March 2023

Reliable extraction of cosmological information from observed cosmic microwave background (CMB) maps may require removal of strongly foreground-contaminated regions from the analysis. In this paper, we employ an artificial neural network (ANN) to predict the full-sky CMB angular power spectrum between intermediate and large angular scales from the partial-sky spectrum obtained from a masked CMB temperature anisotropy map. We use a simple ANN architecture with one hidden layer containing 895 neurons. Using 1.2 × 105 training samples of full-sky and corresponding partial-sky CMB angular power spectra at HEALPix pixel resolution parameter N
side = 256, we show that the spectrum predicted by our ANN agrees well with the target spectrum at each realization for the multipole range 2 ≤ l ≤ 512. The predicted spectra are statistically unbiased, and they preserve the cosmic variance accurately. Statistically, the differences between the mean predicted and underlying theoretical spectra are within approximately 3σ. Moreover, the probability densities obtained from predicted angular power spectra agree very well with those obtained from “actual” full-sky CMB angular power spectra for each multipole. Interestingly, our work shows that the significant correlations in input cut-sky spectra due to mode–mode coupling introduced on the partial sky are effectively removed, since the ANN learns the hidden pattern between the partial- and full-sky spectra preserving all of the statistical properties. The excellent agreement of statistical properties between the predicted and the ground truth demonstrates the importance of using artificial intelligence systems in cosmological analysis more widely.
The Oceanus Moving Group: A New 500 Myr Old Host for the Nearest Brown Dwarf
Authors: Gagné Jonathan , Moranta Leslie , Faherty Jacqueline K. , Kiman Rocio , Couture Dominic , Larochelle Arnaud René , Popinchalk Mark , Morrone Daniella
Published: March 2023

We report the discovery of the Oceanus moving group, a ≈500 Myr old group with 50 members and candidate members at distances 2–50 pc from the Sun, using an unsupervised clustering analysis of nearby stars with Gaia DR3 data. This new moving group includes the nearest brown dwarf WISE J104915.57–531906.1 AB (Luhman 16 AB) at a distance of 2 pc, which was previously suspected to be young (600–800 Myr) based on a comparison of its dynamical mass measurements with brown dwarf evolutionary models. We use empirical color–magnitude sequences, stellar activity, and gyrochronology to determine that this new group is roughly coeval with the Coma Ber open cluster, with an isochronal age of 510 ± 95 Myr. This newly discovered group will be useful to refine the age and chemical composition of Luhman 16 AB, which is already one of the best substellar benchmarks known to date. Furthermore, the Oceanus moving group is one of the nearest young moving groups identified to date, making it a valuable laboratory for the study of exoplanets and substellar members, with eight brown dwarf candidate members already identified here.
A Superflare on YZ Canis Minoris Observed by the Seimei Telescope and TESS: Red Asymmetry of Hα Emission Associated with White-light Emission

Published: March 2023

Active M-type stars are known to often produce superflares on the surface. Radiation from stellar (super)flares is important for exoplanet habitability, but the mechanisms are not well understood. In this paper, we report simultaneous optical spectroscopic and photometric observations of a stellar superflare on an active M dwarf, YZ Canis Minoris, with the 3.8 m Seimei telescope and the Transiting Exoplanet Survey Satellite. The flare bolometric energy is

. The Hα emission line profile shows red asymmetry throughout the flare, with a duration of 4.6–5.1 hr. The velocity of the red asymmetry is ∼200–500 km s–1 and the line width of Hα broadens up to 34 ± 14 Å. The redshifted velocity and line width of Hα line decay more rapidly than the equivalent width, and their time evolutions are correlated with that of the white-light emission. This indicates the possibility of the white light, the Hα red asymmetry, and the Hα line broadening originating from nearly the same site, i.e., the dense chromospheric condensation region, heated by nonthermal electrons. On the other hand, the flux ratio of the redshifted excess components to the central components is enhanced one hr after the flare’s onset. This may be due to the main source of the red asymmetry changing to post-flare loops in the later phase of the flare.
Resolving the Emission Regions of the Crab Pulsar’s Giant Pulses. II. Evidence for Relativistic Motion
Authors: Lin Rebecca , van Kerkwijk Marten H. , Main Robert , Mahajan Nikhil , Pen Ue-Li , Kirsten Franz
Published: March 2023

The Crab Pulsar is the prime example of an emitter of giant pulses. These short, very bright pulses are thought to originate near the light cylinder, at ∼1600 km from the pulsar. The pulsar’s location inside the Crab Nebula offers an unusual opportunity to resolve the emission regions, using the nebula, which scatters radio waves, as a lens. We attempt to do this using a sample of 61,998 giant pulses found in coherently combined European VLBI network observations at 18 cm. These were taken at times of relatively strong scattering and hence good effective resolution. From correlations between pulse spectra, we show that the giant pulse emission regions are indeed resolved. We infer apparent diameters of ∼2000 and ∼2400 km for the main and interpulse components, respectively, and show that with these sizes the correlation amplitudes and decorrelation timescales and bandwidths can be understood quantitatively, both in our observations and in previous ones. Using pulse-spectra statistics and correlations between polarizations, we also show that the nebula resolves the nanoshots that comprise individual giant pulses. The implied diameters of ∼1100 km far exceed light-travel-time estimates, suggesting the emitting plasma is moving relativistically, with γ ≃ 104, as inferred previously from drifting bands during the scattering tail of a giant pulse. If so, the emission happens over a region extended along the line of sight by ∼107 km. We conclude that relativistic motion likely is important for producing giant pulses, and may be similarly for other sources of short, bright radio emission, such as fast radio bursts.

Purpose: There has been limited work assessing the use of re-irradiation (re-RT) for local failure following stereotactic spinal radiosurgery (SSRS). We reviewed our institutional experience of conventionally-fractionated external beam radiation (cEBRT) for salvage therapy following SSRS local failure. Materials and Methods: We performed a retrospective review of 54 patients that underwent salvage conventional re-RT at previously SSRS-treated sites. Local control following re-RT was defined as the absence of progression at the treated site as determined by magnetic resonance imaging. Results: Competing risk analysis for local failure was performed using a Fine-Gray model. The median follow-up time was 25 months and median overall survival (OS) was 16 months (95% confidence interval [CI], 10.8–24.9 months) following cEBRT re-RT. Multivariable Cox proportional-hazards analysis revealed Karnofsky performance score prior to re-RT (hazard ratio [HR] = 0.95; 95% CI, 0.93–0.98; p = 0.003) and time to local failure (HR = 0.97; 95% CI, 0.94–1.00; p = 0.04) were associated with longer OS, while male sex (HR = 3.92; 95% CI, 1.64–9.33; p = 0.002) was associated with shorter OS. Local control at 12 months was 81% (95% CI, 69.3–94.0). Competing risk multivariable regression revealed radioresistant tumors (subhazard ratio [subHR] = 0.36; 95% CI, 0.15–0.90; p = 0.028) and epidural disease (subHR = 0.31; 95% CI, 0.12–0.78; p =0.013) were associated with increased risk of local failure. At 12 months, 91% of patients maintained ambulatory function.Conclusion: Our data suggest that cEBRT following SSRS local failure can be used safely and effectively. Further investigation is needed into optimal patient selection for cEBRT in the retreatment setting.

Five new wood-inhabiting fungi, Lyomyces albopulverulentus, L. yunnanensis, Xylodon daweishanensis, X. fissuratus, and X. puerensisspp. nov., are proposed based on a combination of morphological features and molecular evidence. Lyomyces albopulverulentus is characterized by brittle basidiomata, pruinose hymenophore with a white hymenial surface, a monomitic hyphal system with clamped generative hyphae, and ellipsoid basidiospores. Lyomyces yunnanensis is characterized by a grandinioid hymenial surface, the presence of capitate cystidia, and ellipsoid basidiospores. Xylodon daweishanensis is characterized by an odontioid hymenial surface, a monomitic hyphal system with clamped generative hyphae, and broad ellipsoid-to-subglobose basidiospores. Xylodon fissuratus is characterized by a cracking basidiomata with a grandinioid hymenial surface, and ellipsoid basidiospores. Xylodon puerensis is characterized by a poroid hymenophore with an angular or slightly daedaleoid configuration, and ellipsoid-to-broad-ellipsoid basidiospores. Sequences of ITS and nLSU rRNA markers of the studied samples were generated and phylogenetic analyses were performed with the maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogram based on the ITS+nLSU rDNA gene regions (Fig. 1) included six genera within the families Chaetoporellaceae, Hyphodontiaceae, Hymenochaetaceae, and Schizoporaceae (Hymenochaetales)—Fasciodontia, Hastodontia, Hyphodontia, Kneifiella, Lyomyces, and Xylodon—in which the five new species were grouped into genera Lyomyces and Xylodon. The phylogenetic tree inferred from the ITS sequences highlighted that Lyomyces albopulverulentus formed a monophyletic lineage and was then grouped closely with L. bambusinus, L. orientalis, and L. sambuci; additionally, L. yunnanensis was sister to L. niveus with strong supports. The topology, based on the ITS sequences, revealed that Xylodon daweishanensis was retrieved as a sister to X. hyphodontinus; X. fissuratus was grouped with the four taxa X. montanus, X. subclavatus, X. wenshanensis, and X. xinpingensis; and X. puerensis was clustered with X. flaviporus, X. ovisporus, X. subflaviporus, X. subtropicus, and X. taiwanianus.
Entre le regain et l’incendie : l’étape oubliée du compostage industriel, voie médiane abandonnée du traitement des ordures ménagères (Île-de-France, années 1940 – années 1990)
Authors: Dufour Étienne
Published: March 2023

Focalisée sur les grandes innovations techniques et les trajectoires sociotechniques dominantes, l’histoire du traitement des déchets organiques urbains a partiellement négligé les techniques alternatives de recyclage agricole. Celles-ci ont pourtant perduré dans les usages jusque tard dans certains contextes territoriaux. Dans la région parisienne, entre les années 1940 et les années 1990, une partie des flux de matières résiduelles des villes de l’agglomération a ainsi continué d’être orientée, de manière assez décentralisée et en dehors des grands réseaux techniques, vers les sols cultivés des campagnes voisines. Avant que ne s’impose assez tardivement et presque sans partage le système du tout-réseau qui destine l’ensemble des ordures à la destruction-dispersion en usine d’incinération ou à l’enfouissement en décharges, ces techniques alternatives telles que le compostage ont même connu un certain regain. Le compostage industriel s’est ainsi développé de façon éphémère autour des années 1960. Cependant, il ne survit pas aux années 1970 qui reconfigurent profondément les rapports de force et la hiérarchie entre les technologies. En suivant la trajectoire de ces alternatives, une autre histoire du traitement des déchets se dessine, où villes et campagnes maintiennent de fertiles liens organiques avant que les unes et les autres ne scellent définitivement (?) leur rupture à la fin du XX e  siècle. Elle permet d’esquisser quelques raisons de ce succès éphémère puis de cet échec.
Handicap et institution : Posture du psychologue face à la prise en compte de la diversité du public
Authors: Pittiglio Serge
Published: March 2023

L'institution scolaire doit être pensée et organisée autour du principe de l'inclusion de tous les élèves. Tous les professionnels témoignent de la complexité accrue de leurs pratiques lorsqu’il s’agit de prendre en compte l'hétérogénéité du public scolaire tout en visant l'objectif de garantir les apprentissages de façon individuelle et personnalisée. Cet article interroge les conséquences de ces évolutions sur la posture des psychologues, notamment au regard de la nécessaire mise en place de projets de scolarité qui associent authentiquement tous les membres de l’équipe éducative plutôt de prendre la forme d’injonctions pensées par les uns pour être mises en œuvre par les autre.

Rice is grown almost everywhere in the world, especially in Asian countries, because it is part of the diets of about half of the world's population. However, farmers and planting experts have faced several persistent agricultural obstacles for many years, including many rice diseases. Severe rice diseases might result in no grain harvest; hence, in the field of agriculture, a fast, automatic, less expensive, and reliable approach to identifying rice diseases is widely needed. This paper focuses on how to build a lightweight deep learning model to detect rice plant diseases more precisely. To achieve the above objective, we created our own CNN model "LW17" to detect rice plant disease more precisely in comparison to some of the pre-trained models, such as VGG19, InceptionV3, MobileNet, Xception, DenseNet201, etc. Using the proposed methodology, we took UCI datasets for disease detection and tested our model with different layers, different training–testing ratios, different pooling layers, different optimizers, different learning rates, and different epochs. The Light Weight 17 (LW17) model reduced the complexity and computation cost compared to other heavy deep learning models. We obtained the best accuracy of 93.75% with the LW17 model using max pooling with the "Adam" optimizer at a learning rate of 0.001. The model outperformed the other state-of-the-art models with a limited number of layers in the architecture.
Modeling COVID-19 pandemic with financial markets models: The case of Jaén (Spain)

The main objective of this work is to test whether some stochastic models typically used in financial markets could be applied to the COVID-19 pandemic. To this end, we have implemented the ARIMAX and Cox-Ingersoll-Ross (CIR) models originally designed for interest rate pricing but transformed by us into a forecasting tool. For the latter, which we denoted CIR*, both the Euler-Maruyama method and the Milstein method were used. Forecasts obtained with the maximum likelihood method have been validated with 95% confidence intervals and with statistical measures of goodness of fit, such as the root mean square error (RMSE). We demonstrate that the accuracy of the obtained results is consistent with the observations and sufficiently accurate to the point that the proposed CIR* framework could be considered a valid alternative to the classical ARIMAX for modelling pandemics.
Stability of multi-population traffic flows
Authors: Hayat Amaury , Piccoli Benedetto , Xiang Shengquan
Published: March 2023

Traffic waves, known also as stop-and-go waves or phantom jams, appear naturally as traffic instabilities, also in confined environments as a ring-road. A multi-population traffic is studied on a ring-road, comprised of drivers with stable and unstable behavior. There exists a critical penetration rate of stable vehicles above which the system is stable, and under which the system is unstable. In the latter case, stop-and-go waves appear, provided enough cars are on the road. The critical penetration rate is explicitly computable, and, in reasonable situations, a small minority of aggressive drivers is enough to destabilize an otherwise very stable flow. This is a source of instability that a single population model would not be able to explain. Also, the multi-population system can be stable below the critical penetration rate if the number of cars is sufficiently small. Instability emerges as the number of cars increases, even if the traffic density remains the same (i.e., number of cars and road size increase similarly). This shows that small experiments could lead to deducing imprecise stability conditions.
L’ambassadeur français aux droits LGBT+

Published: March 2023

Pour la première fois en France, un ambassadeur aux droits LGBT+ a été nommé en octobre dernier. L’indétermination juridique du statut de ce nouvel acteur interroge la pertinence d’une diplomatie LGBTQI+ française. Une perspective critique queer de cette initiative permet de l’appréhender comme un outil – cette fois-ci discursif – d’instrumentalisation étatique de la protection des personnes LGBTQI+, aux conséquences pouvant contredire l’objectif initialement affiché de protéger les droits des personnes LGBTQI+.
Metastatic choriocarcinoma of the breast: report of a rare case and review of literature
Authors: Imam Mohammed Ibrahim
Published: March 2023

Choriocarcinoma (CC) is a malignant tumor of trophoblastic tissue composed of cytotrophoblastic, intermediate and syncytiotrophoblast cells. Choriocarcinoma predominantly has a gestational origin. The non-gestational type is said to arise from the gonads and pluripotent germ cells. It is a rapidly invasive tumor and metastasizes widely, but it has a good response to chemotherapy once identified. Metastatic choriocarcinoma are extremely rare in the breast. Choriocarcinomatous differentiation has also been described in neoplasm arising from many organs including colon, stomach, rectum, urinary bladder and lung. In this case report, the history, physical examination, laboratory findings and pathological findings of metastatic choriocarcinoma of the breast in a 24-year-old female are described and previous literature about metastatic choriocarcinoma is reviewed.
