Los orígenes de una ciudad olímpica: Barcelona y el asociacionismo deportivo decimonónico ante la gestación de los primeros Juegos Olímpicos
Authors: TORREBADELLA I FLIX Xavier 
Published: May 2023

A mediados del siglo XIX Barcelona emprendió un acelerado proceso de expansión industrial y empresarial que la consolidó como la ciudad más próspera de España. Esta posición provocó la presencia de una elevada colonia extranjera europea, que asimismo participó del asociacionismo recreativo del llamado sport. Los vínculos entre la elitista colonia extranjera y la emergente burguesía de Barcelona facilitaron la puesta en marcha de un fenómeno asociativo de signo liberal sin precedentes que tomó su máxima expresión en las prácticas gimnástico-deportivas. Esta consideración representó a finales del siglo XIX, coincidiendo con la gestación de los Juegos Olímpicos modernos, la imagen que sustentó a Barcelona como la precursora y primer referente del incipiente asociacionismo deportivo en España. Palabras clave: Barcelona, historia del deporte, asociacionismo deportivo, Juegos Olímpicos, siglo XIX. THE ORIGINS OF AN OLYMPIC CITY: BARCELONA AND THE 19th CENTURY SPORTING ASSOCIATIONS TO THE GESTATION OF THE FIRST OLYMPIC GAMES In the mid-19th century Barcelona started an accelerated process of industrial and business expansion which established it as the most prosperous city of Spain. This position led to the presence of a high European foreign colony, which also participated in recreational associations of the so-called sport. The links between the elitist foreign colony and the emerging bourgeoisie of Barcelona provided implementation underway an associative phenomenon of liberal sign unprecedented that took its maximum expression in gymnastics and sport activities. This consideration represented at the end of the 19th century, coinciding with the emergence of the modern Olympic Games, the image which propped up Barcelona as the precursor and first reference for budding sports associations in Spain.Keywords: Barcelona, history of sports, sports associations, Olympic Games, 19th century

AbstractElectrophysiological recording and stimulation are the gold standard for functional mapping during surgical and therapeutic interventions as well as capturing cellular activity in the intact human brain. A critical component probing human brain activity is the interface material at the electrode contact that electrochemically transduces brain signals to and from free charge carriers in the measurement system. Here, we summarize state-of-the-art electrode array systems in the context of translation for use in recording and stimulating human brain activity. We leverage parametric studies with multiple electrode materials to shed light on the varied levels of suitability to enable high signal-to-noise electrophysiological recordings as well as safe electrophysiological stimulation delivery. We discuss the effects of electrode scaling for recording and stimulation in pursuit of high spatial resolution, channel count electrode interfaces, delineating the electrode–tissue circuit components that dictate the electrode performance. Finally, we summarize recent efforts in the connectorization and packaging for high channel count electrode arrays and provide a brief account of efforts toward wireless neuronal monitoring systems.

AbstractMagnetic functional materials remain an area of research interest for applications in electronic devices. Among these materials, Mn50Pt50 alloy has received a great deal of attention in practical potential applications such as spintronics due to its high-thermal and magnetic stability. It was reported previously that L10 Mn50Pt50 alloy shows ferromagnetic ordering at room temperature. In this study, the effect of the partial substitution of Pt with Co was investigated using density functional theory (DFT) approach. The thermodynamic, magnetic and mechanical properties were determined to check the stability of Mn50Pt50-xCox alloys. The results showed that the L10 phase has the lowest heat of formation when the c/a ratio is 1.10 for 6.25 at.% Co. Overall magnetic moments improve with an increase in Co compositions when the c/a ratio is 1.10. The obtained results reveal that Mn50Pt50-xCox alloys exhibit attractive magnetic and mechanical properties for future magnets in spintronics applications.

O efeito do fim das coligações nas eleições proporcionais na composição da Câmara dos Deputados eleita em 2022
Authors: Nicolau Jairo 
Published: May 2023

As eleições de 2022 foram as primeiras, desde a redemocratização, em que os partidos foram proibidos de se coligarem para deputado federal e estadual. O artigo avalia o impacto dessa mudança na composição das bancadas eleitas para a Câmara dos Deputados. A primeira seção mostra as principais características do modelo de representação proporcional utilizado no Brasil. A seção seguinte faz um resumo das alterações promovidas pelas reformas eleitorais de 2017 e 2021. A terceira seção analisa a evolução de alguns indicadores da representação dos partidos, tomando as unidades a federação como unidade de análise: o número de partidos que concorreram; o número de partidos que elegeu deputados; a fragmentação partidária eleitoral e parlamentar. Todos os indicadores mostram que houve uma redução significativa do número de partidos representados e da fragmentação partidária nas eleições para a Câmara dos Deputados em 2022; essa redução é observada em todas as unidades da federação. O artigo mostra que o fim das coligações teve um papel decisiva para a reconfiguração do quadro partidário brasileiro.

Significance Statement
Nephrosclerosis (glomerulosclerosis, interstitial fibrosis, and tubular atrophy) is the defining pathology of both kidney aging and CKD. Optimal thresholds for nephrosclerosis that identify persons with a progressive disease are unknown. This study determined a young-age threshold (18–29 years) and age-based 95th percentile thresholds for nephrosclerosis on the basis of morphometry of kidney biopsy sections from normotensive living kidney donors. These thresholds were 7.1-fold to 36-fold higher in older (70 years or older) versus younger (aged 18–29 years) normotensive donors. Age-based thresholds, but not young-age threshold, were prognostic for determining risk of progressive CKD among patients who underwent a radical nephrectomy or a for-cause native kidney biopsy, suggesting that age-based thresholds are more useful than a single young-age threshold for identifying CKD on biopsy.

Background
Nephrosclerosis, defined by globally sclerotic glomeruli (GSG) and interstitial fibrosis and tubular atrophy (IFTA), is a pathology of both kidney aging and CKD. A comparison of risk of progressive CKD using aged-based thresholds for nephrosclerosis versus a single young-adult threshold is needed.

Methods
We conducted morphometric analyses of kidney biopsy images for %GSG, %IFTA, and IFTA foci density among 3020 living kidney donors, 1363 patients with kidney tumor, and 314 patients with native kidney disease. Using normotensive donors, we defined young-age thresholds (18–29 years) and age-based (roughly by decade) 95th percentile thresholds. We compared age-adjusted risk of progressive CKD (kidney failure or 40% decline in eGFR) between nephrosclerosis that was “normal compared with young,” “normal for age but abnormal compared with young,” and “abnormal for age” in patients with tumor and patients with kidney disease.

Results
The 95th percentiles in the youngest group (18–29 years) to the oldest group (70 years or older) ranged from 1.7% to 16% for %GSG, 0.18% to 6.5% for %IFTA, and 8.2 to 59.3 per cm2 for IFTA foci density. Risk of progressive CKD did not differ between persons with nephrosclerosis “normal compared with young” versus “normal for age but abnormal compared with young.” Risk of progressive CKD was significantly higher with %GSG, %IFTA, or IFTA foci density that was abnormal versus normal for age in both cohorts.

Conclusions
Given that increased risk of progressive CKD occurs only when nephrosclerosis is abnormal for age, age-based thresholds for nephrosclerosis seem to be better than a single young-age threshold for identifying clinically relevant CKD.
Differentiated, immunobased approach of anaplastic large cell lymphoma treatment in children and adolescents: literature review and protocol ALCL-NII DOG-2003 results
Authors: Volkova A. S. , Valiev T. T. 
Published: May 2023

Background. Anaplastic large cell lymphoma (ALCL) is a rare variant of highly aggressive lymphomas in children and adolescents. ALCL is characterized by a heterogeneous clinical manifestation with nodal and extranodal lesions, various morphological variants, variable expression of T-cell markers and cytogenetic aberrations involving the ALK gene. Due to the rarity of this disease (up to 10–15 % of all non-Hodgkin’s lymphomas in children), there are no uniform standards for ALCL therapy. Block treatment schemes similar to those applied in the treatment of B-cell non-Hodgkin’s lymphomas are used; less often there can be used protocols similar to the therapy of acute lymphoblastic leukemia. Taking into account the unfavorable effect on the prognosis of T-cell markers expression in ALCL, we developed protocol ALCL-NII DOG-2003, which considered the immunological features of the tumor.Aim. To assess the effectiveness of differentiated immunobased ALCL therapy by domestic protocol ALCL-NII DOG-2003.Materials and methods. From 01.03.1997 to 01.10.2022, 60 patients with primary diagnosed ALCL were included in the study. The diagnosis was based on histological, immunohistochemical and cytogenetic criteria of WHO classification of hematopoietic and lymphoid tissues tumors. According to treatment program, patients were subdivided in 2 groups: patients treated by NHL-BFM 95 protocol (n = 21) and by ALCL-NII DOG-2003 (n = 39). The male:female ratio was 1,3:1 in group of patients with NHL-BFM 95 protocol and 1,4:1 – in ALCL-NII DOG 2003. The effectiveness assessment was based on overall, event-free and relapse-free survival with SPSS 21.0 computed program. The differences between groups were significant with p ≤0.05.Results. The use of risk-adopted, immuno-oriented protocol made it possible to obtain a 10‑year EFS in 97.4 ± 2.6 %, whereas results of the standard NHL-BFM 95 protocol are 63.9 ± 10 % (p = 0.001).Conclusion. The use of a differentiated approach to ALCL treatment, considering not only the stage and prognostic risk group, but also the immunological features of the tumor, is more effective, and allows achieving significantly higher survival rates, than standard program (NHL-BFM 95).
Stochastic Ground-Motion Simulation of the 2021 Mw 5.9 Woods Point Earthquake: Facilitating Local Probabilistic Seismic Hazard Analysis in Australia
Authors: Tang Yuxiang , Martin Mai P. 
Published: May 2023

ABSTRACT
The 2021 Mw 5.9 Woods Point event is the largest onshore earthquake that has occurred in the recorded history of southeastern Australia since European settlement. To study its source and ground-motion characteristics and to extract information for local seismic hazard analysis, we employ a stochastic finite-fault simulation approach to simulate ground motions for this event based on the observations collected from 36 onshore stations. We determine the regional distance-dependent attenuation parameters using the horizontal Fourier acceleration amplitude spectrum in the frequency range of 0.1–20 Hz. We parameterize path parameters using different models to consider uncertainties and sensitivities. To investigate local site effects, we construct a VS30-based site amplification model. Source parameters are then determined by fitting the theoretical Brune’s ω2 model with a reference Fourier source spectrum at 1.0 km. The κ0 value for the reference rock site is estimated as κ0=0.01  s, and dynamic stress drop is found to be 41.0 MPa by minimizing the overall absolute residual of 5% damped pseudospectral acceleration. We validate the simulations by comparing simulated and observed ground motions in terms of various intensity measurements; analyses of residuals show that the simulations are in good agreement with observations (average residual is close to 0). To facilitate future probabilistic seismic hazard analysis, six selected ground-motion models are ranked using the deviance information criteria based on an independent data set consisting of field observations and simulated ground motions.

Authors: Aggarwal Paratibha , Gurjar Gulshan K. , Aggarwal Yogesh , Kumar Pankaj 
Published: May 2023

The paper deals with the use of Deep Neural Networks (DNN), Artificial Neural Network (ANN), and Random Forest (RF) for estimating the 28- day compressive strength of self-compacting concrete (SCC) containing silica and filler (fly ash, marble powder, and lime powder) with a comparative performance analysis of all techniques. A total of 179 data were taken from literature already published with eight input variables for modelling. The evaluation and comparison of the performance of predicted models were made using the same datasets in training and testing based on correlation coefficient (CC), Coefficient of determination (R2), root mean square error (RMSE), and mean absolute error (MAE). The results showed that proposed model's performance could be improved when training takes place in a Deep Neural Network model with multiple hidden layers. Sensitivity analysis was used to quantify the effect of different variables on concrete strength with coarse aggregate greatly affecting the compressive strength of SCC, followed by fine aggregate content and quantity of silica. A dependable prediction tool is provided through this investigation which suggests that the present model can help scientists and engineers in the optimization of the mixture design of SCC.

The relevance of the research is determined by the modern trend in the field of thermal power engineering and heat engineering for the transition from traditional gaseous fuel (methane) to the use of hydrogen, methane-hydrogen mixtures, as well as thermochemical conversion gases. Switching to new non-design fuel is justified by considerations of reducing the negative impact on the environment and increasing the thermal efficiency of fuel combustion plants. In this case, the use of fuels with a composition different from the design one will affect the heat transfer processes. The main aim: carrying out a comparative analysis of indicators of the intensity of radiant and convective heat transfer of combustion products of non-design fuels, such as hydrogen, methane-hydrogen mixture and thermochemical conversion gases. As an assumption in the formulation of the problem and objectives of the study, the constancy of the heat release power in the apparatus due to changes in the amount of fuel burned was taken. Objects: heat exchange surface of a fire-tube hot water boiler. Methods: carrying out numerical calculation using traditional approaches to determine the indicators of the intensity of heat transfer in the system «combustion products – metal wall of the pipe of thermal power plants». We also used the relations tested earlier by other authors to calculate the thermophysical parameters of gas mixtures. Results. According to the results of the performed comparative calculations, we can conclude that the transition from the use of conventional fuel (natural gas/methane) to its thermochemical conversion gases under the considered conditions has almost no effect on the integral heat transfer performance. To a greater extent, this transition is caused by changes in the intensity of heat transfer for products of combustion of hydrogen and methane-hydrogen mixture, which will affect the operation of thermal power and heat technological installations. At the same time, it is necessary to conduct additional research on the combustion kinetics of thermochemical methane conversion gases, their thermophysical properties, etc., because the hardware design, type of the catalyst used and operating parameters of the process will affect the composition of obtained synthesis gas.
Las kancha circulares: espacios de interacción social en la sierra norte del Perú
Authors: Herrera Alexander 
Published: May 2023

Este trabajo aborda el papel activo y cambiante de las kancha de planta circular, estructuras públicas organizadas en torno a un patio abierto y que son comunes en la sierra norcentral del Perú. Se discuten la distribución y cronología de este tipo de monumentos a partir de las investigaciones a escala regional y local en la región de Los Conchucos y la parte media del Callejón de Huaylas. El enfoque en su emplazamiento en el paisaje y la estructura del espacio interno, ligado al análisis de los restos de cerámica hallados en las excavaciones realizadas en el sitio de Gotushjirka (distrito de San Nicolás, provincia de Carlos Fermín Fitzcarrald, región Áncash), revela que se trata de espacios diseñados para crear un impresionante sentido de “liminalidad”, estrechamente vinculado con prácticas mortuorias. La remodelación de kancha circulares según un plano ortogonal, detectada en dos sitios de la Cordillera Blanca —Kishwar (distrito deYanama, provincia de Yungay) y Keushu (distrito y provincia de Yungay)— suscita interrogantes acerca de trayectorias sociohistóricas disímiles a nivel subregional.

Authors: Dick Daniel T , Henningsen David Dryden 
Published: May 2023

Social exchange theory and equity theory were used to examine the perception of leaders in a small group context. Participants (n = 154), involved in a semester long group project assessed their leaders contributions to the task and maintenance of the group using measures gauging social exchange and equity forces. These measures were regressed onto desire to work with the leader again in the future. Overall, the results indicate greater support for social exchange theory.
