Introduction: The efficacy of mind-body therapies to manage urinary incontinence in women is outdated and inconclusive. This review aims to determine the efficacy of mind - body therapies for Stress Urinary Incontinence (SUI) in women. Methods: The databases AMED, CINAHL, EMBASE, Medline, Physiotherapy Evidence Database (PEDro), PubMed, Scopus, and Web of Science, were searched from database inception until May 2020. Randomized controlled trials comparing mind-body therapies to control were included. The methodological quality and the quality of the evidence were evaluated using the Physiotherapy Evidence Database (PEDro) scale and the Grading of Recommendations, Assessment, Development, and Evaluation tool, respectively. The risk of bias was assessed using the Cochrane risk of bias tool. Results: Six studies were included in the review. Pooled analysis of data from two studies of low to high methodological quality, low-grade evidence revealed a statistically significant decrease in the number of SUI episodes in the yoga group than in the control group (MD 0.83 [95% CI-1.64 to 0.02]; p=0.04). Pooled analysis of three methodologically low-quality, very low-grade studies revealed no significant difference between groups receiving Paula exercise and pelvic floor muscle training on grams of urine lost in the 1h pad test (MD 0.15 [95% CI-1.15 to 1.46] p=0.82). Conclusions: This review found hatha yoga poses intended to address the pelvic floor as beneficial for managing SUI in women. Yoga is a low-risk intervention and therefore it may be considered for clinical use. The effect of Paula exercise on SUI remains inconclusive.
Modelling Cationic Diffusion in Nickel-Based Honeycomb Layered Tellurates using Vashishta-Rahman Interatomic Potential and Relevant Insights

Published: May 2021

Although the fascinatingly rich crystal chemistry of honeycomb layered oxides has been accredited as the propelling force behind their remarkable electrochemistry, the atomistic mechanisms surrounding their operations remain unexplored. Thus, herein, we present an extensive molecular dynamics study performed systematically using a reliable set of inter-atomic potential parameters of A2Ni2TeO6 (where A = Li, Na, and K). We demonstrate the effectiveness of the Vashishta-Rahman form of the inter-atomic potential in reproducing various structural and transport properties of this promising class of materials and predict an exponential increase in cationic diffusion with larger inter-layer distances. The simulations demonstrate the correlation between broadened inter-layer (inter-slab) distances associated with the larger ionic radii of K and Na compared to Li and the enhanced cationic conduction exhibited in K2Ni2TeO6 and Na2Ni2TeO6 relative to Li2Ni2TeO6. Whence, our findings connect lower potential energy barriers, favourable cationic paths and wider bottleneck size along the cationic diffusion channel within frameworks (comprised of larger mobile cations) to the improved cationic diffusion experimentally observed in honeycomb layered oxides. Furthermore, we elucidate the role of inter-layer distance and cationic size in cationic diffusion. Our theoretical studies reveal the dominance of inter-layer distance over cationic size, a crucial insight into the further performance enhancement of honeycomb layered oxides.

Machine Learning of Quasiparticle Energies in Molecules and Clusters
Authors: Çaylak Onur , Baumeier Björn
Published: May 2021

We present a ∆-Machine Learning approach for the prediction of GW quasiparticle energies (∆MLQP) and photoelectron spectra of molecules and clusters, using orbital-sensitive graph-based representations in kernel ridge regression based supervised learning. Coulomb matrix, Bag-of-Bonds, and Bonds-Angles-Torsions representations are made orbital-sensitive by augmenting them with atom-centered orbital charges and Kohn–Sham orbital energies, which are both readily available from baseline calculations on the level of density-functional theory (DFT). We first illustrate the effects of different constructions of the orbital-sensitive representations (OSR) on the prediction of frontier orbital energies of 22K molecules of the QM8 dataset, and show that is is possible to predict the full photoelectron spectrum of molecules within the dataset using a single model with a mean-absolute error below 0.1eV. We further demonstrate that the OSR-based ∆MLQP captures the effects of intra- and intermolecular conformations in application to water monomers and dimers. Finally, we show that the approach can be embedded in multiscale simulation workflows, by studying the solvatochromic shifts of quasiparticle and electron-hole excitation energies of solvated acetone in a setup combining Molecular Dynamics, DFT, the GW approximation and the Bethe–Salpeter Equation. Our findings suggest that the ∆MLQP model allows to predict quasiparticle energies and photoelectron spectra of molecules and clusters with GW accuracy at DFT cost.
Environmentally Sensitive Luminescence Reveals Spatial Confinement, Dynamics and Their Molecular Weight Dependence in a Polymer Glass
Authors: Picken Stephen , Filonenko Georgy
Published: May 2021

Polymer glasses have an irregular structure. Among the causes for such complexity are the chemically distinct chain end-groups that are the most abundant irregularities in any linear polymer. In this work we demonstrate that chain end induced defects allow polymer glasses to create confined environments capable of hosting small emissive molecules. Using environmentally sensitive luminescent complexes we show that the size of these confinements depends on molecular weight and can dramatically affect the photoluminescence of free or covalently bound emissive complexes. We confirm the impact of chain end confinement on the bulk glass transition in poly(methyl acrylate) and show that commonly observed Tg changes induced by the chain ends should have a structural origin. Finally, we demonstrate that size and placement of luminescent molecular probes in pMA can dramatically affect the probe luminescence and its temperature dependence suggesting that polymer glass is a highly irregular and complex environment marking its difference with conventional small molecule solvents. Considering the ubiquity of luminescent glassy materials, our work lays down a blueprint for designing them with structural considerations in mind, ones where packing density and chain end size are key factors.
Stacking Gaussian Processes to Improve pKa Predictions in the SAMPL7 Challenge
Authors: Raddi Robert , Voelz Vincent
Published: May 2021

Accurate predictions of acid dissociation constants are essential to rational molecular design in the pharmaceutical industry and elsewhere. There has been much interest in developing new machine learning methods that can produce fast and accurate pKa predictions for arbitrary species, as well as estimates of prediction uncertainty. Previously, as part of the SAMPL6 community-wide blind challenge, Bannan et al. approached the problem of predicting pKas by using a Gaussian process regression to predict microscopic pKas, from which macroscopic pKa values can be analytically computed. While this method can make reasonably quick and accurate predictions using a small training set, accuracy was limited by the lack of a sufficiently broad range of chemical space in the training set (e.g., the inclusion of polyprotic acids). Here, to address this issue, we construct a deep Gaussian Process (GP) model that can include more features without invoking the curse of dimensionality. We trained both a standard GP and a deep GP model using a database of approximately 3500 small molecules curated from public sources, filtered by similarity to targets. We tested the model on both the SAMPL6 and more recent SAMPL7 challenge, which introduced a similar lack of ionizable sites and/or environments found between the test set and the previous training set. The results show that while the deep GP model made only minor improvements over the standard GP model for SAMPL6 predictions, it made significant improvements over the standard GP model in SAMPL7 macroscopic predictions, achieving a MAE of 1.5 pKa.

La investigación y la universidad, nuevas épocas para el desarrollo

A la universidad se le adjudican tres misiones esenciales. La enseñanza (o sea, producir licenciados o profesionales) es la más notoria y manifiesta de todas; tanto que la inmensa mayoría de sus recursos están dedicados a esa misión. Pero también tiene otra misión: la búsqueda y creación de conocimientos: la universidad es el sitio donde se produce el saber humano. Y, por último, tercera misión, debe relacionarse con su entorno social, en torno del cual nación, en el cual vive y del cual depende; a esta última misión comúnmente la llaman “extensión”, y las universidades la cubren prestando servicios a las comunidades que la rodean (servicios vinculados a sus facultades: médicos, jurídicos, técnicos), pero también la investigación sobre problemas de su medio, local o nacional, que diagnostica y plantea soluciones, es parte importantísima de esa relación universidad-entorno. Estas tres misiones u objetivos están inscritas en las leyes y demás textos que rigen y definen a estas instituciones. También se nombra a veces una cuarta misión: la de transmitir el saber. Sin embargo, la transmisión del conocimiento está implícita en el acto de la enseñanza y en la acción de la investigación (cuyo ciclo completo supone la publicación de los resultados).

La Psicología Jurídica un área de trabajo e investigación especializada, cuyo objeto es el estudio del comportamiento de los actores jurídicos en el ámbito del derecho, la ley y la justicia. Esta especialidad comprende el estudio, explicación, promoción, evaluación, prevención y en su caso, asesoramiento y tratamiento de aquellos fenómenos conductuales y relacionales que inciden en el comportamiento legal de las personas, mediante la utilización de métodos propios de la Psicología científica. En América Latina, la definición de la Psicología Jurídica ha ido en la misma línea, dado que es entendida como la encargada de los problemas relacionados con el comportamiento humano y que surgen en el sistema jurídico legal (policía, juzgados, tribunales, correccionales para infractores e instituciones carcelarias y penitenciarias, etc.). Reconocida como la Psicología aplicada en el campo del Derecho, que le ofrece al psicólogo un campo de acción interdisciplinario y que le permite asumir su ejercicio, utilizando los instrumentos que le son propios en armonía con elementos ofrecidos por el campo jurídico, como son las actuaciones judiciales y extrajudiciales, el medio carcelario y el conjunto de individuos sujetos de obligación o derecho que los hacen valer.
Determination of the permittivity of materials in a volume resonator with allowance for the surface roughness
Authors: Krylov V. P.
Published: May 2021

The accuracy of determining the permittivity of the material depends on the thickness of the intermediate layer with variable dielectric characteristics formed on the surface of the sample upon manufacturing. We present the results of studying the influence of the surface roughness of the test sample on the accuracy of determining the permittivity using the resonator method. An algorithm for calculating the permittivity in a volumetric cylindrical resonator is proposed, taking into account the roughness value and the residual gap. Using the matrix method for calculating the wave transmitted through the plate, a model for determination of the dielectric permittivity of a multilayer sample using a measuring resonator is developed. The results obtained can be used to improve the accuracy of the permittivity determination in a volume resonator when testing the samples with a roughness exceeding the required standard.

Published: May 2021

Background

Population-based studies characterising outcomes of COVID-19 in European settings are limited, and effects of socio-economic status (SES) on outcomes have not been widely investigated.

Aim

We describe the epidemiological characteristics of COVID-19 cases, highlighting incidence and mortality rate differences across SES during the first wave in Barcelona, Catalonia, Spain.

Methods

This population-based study reports individual-level data of laboratory-confirmed COVID-19 cases diagnosed from 24 February to 4 May 2020, notified to the Public Health Agency of Barcelona and followed until 15 June 2020. We analysed end-of-study vital status and the effects of chronic conditions on mortality using logistic regression. Geocoded addresses were linked to basic health area SES data, estimated using the composed socio-economic index. We estimated age-standardised incidence, hospitalisation, and mortality rates by SES.

Results

Of 15,554 COVID-19-confirmed cases, the majority were women (n = 9,028; 58%), median age was 63 years (interquartile range: 46–83), 8,046 (54%) required hospitalisation, and 2,287 (15%) cases died. Prevalence of chronic conditions varied across SES, and multiple chronic conditions increased risk of death (≥ 3, adjusted odds ratio: 2.3). Age-standardised rates (incidence, hospitalisation, mortality) were highest in the most deprived SES quartile (incidence: 1,011 (95% confidence interval (CI): 975–1,047); hospitalisation: 619 (95% CI: 591–648); mortality: 150 (95% CI: 136–165)) and lowest in the most affluent (incidence: 784 (95% CI: 759–809); hospitalisation: 400 (95% CI: 382–418); mortality: 121 (95% CI: 112–131)).

Conclusions

COVID-19 outcomes varied markedly across SES, underscoring the need to implement effective preventive strategies for vulnerable populations.

Published: May 2021

The purpose of the research is to determine the level of conservation and management of signifi Permian System geoheritage objects in special protected natural areas and world museum collections as well as to rehabilitate and preserve Perm Region on the Permian museums and geoheritage map. Th geographical distribution of modern geotoponyms of the Permian geological System, identifi in 1841 in Russia and named aft the city of Perm, was made in relation to the stratigraphic (geochronological) scale subdivisions at the place of discovery by the level of system, series, stage (period, epoch, age respectively), including Global Boundary Stratotype Sections and Points (GSSP). Geographical distribution of the geoheritage sites allows highlighting their primary and secondary localization for the Permian Period. Signifi objects of the Permian heritage were analyzed in conjunction with its representation of the place of its discovery based on the protected areas and signifi museum collections network. Ex situ conservation of the Permian spatial collections' localization is caused by two main factor: territorial linkage to the localities (primary type research and acquisition), and acquisition of the most signifi collections by museums, universities and research institutes (secondary type of research and acquisition). Th analysis of signifi Permian geoheritage sites in the world spatial distribution allows us to identify nine main clusters. Key clusters of the Permian refer to CisUral region, South of the USA, and WestEastern China (with the GSSP for the Lower, Middle, and Upper Perm respectively). Signifi in situ sites let develop geotourism activities. Proposals for the Permian geoheritage system optimization in the Perm Region are formulated in conjunction with the network of protected areas, university research and key museum collections.

variaciones sobre temas de carlos alchourrón y eugenio bulygin. derrotabilidad, lagunas axiológicas e interpretación
Authors: Guastini Riccardo
Published: May 2021

El trabajo pretende analizar las relaciones entre la derrotabilidad de las normas y las lagunas axiológicas desde la perspectiva de una teoría realista de la interpretación. Algunos ejemplos muestran que los dos conceptos denotan fenómenos que se presentan a lo largo del proceso de interpretación y que dependen de las estrategias interpretativas de los juristas. El análisis de los ejemplos permite desprender algunas conclusiones: entre otras, la siguientes: 1. La derrotabilidad no es una propiedad objetiva de las normas, antecedente a toda interpretación: por el contrario, es una de sus posibles consecuencias, es el resultado de una operación interpretativa (en particular, de una interpretación no literal, sino restrictiva, por medio de la cual se crean excepciones implícitas). 2. Al derrotar una norma se excluyen de su alcance algunos supuestos (que, sin embargo, de acuerdo con una distinta interpretación sí estarían reglados por la norma); si dichos supuestos no resultan reglados por otra norma del sistema, el sistema está lagunoso; entonces, la derrota produce una laguna. 3. Dicha laguna puede ser considerada axiólogica o normativa desde perspectivas interpretativas diferentes. Es decir, no se pueden distinguir las lagunas normativas de las lagunas axiológicas independientemente de la interpretación. Entonces incluso las lagunas normativas son variables dependientes de la interpretación: según una interpretación determinada hay una laguna normativa, mientras que según otra interpretación esta laguna milagrosamente desaparece, no subsiste en tanto laguna normativa, y entonces se convierte en laguna axiológica. 4. La derrotabilidad de las normas y las lagunas axiológicas dependen no de la presencia, en el sistema jurídico, de principios, como suponen algunos autores, sino de las valoraciones de los intérpretes, que a menudo toman la forma de «teorías» jurídicas o tesis dogmáticas: algo construido por los juristas antes e independientemente de la interpretación de uno u otro enunciado normativo específico.

Este documento discute una de las relaciones sociales de la tríada del análisis de modos de coordinación de K. Polanyi: la tierra (recursos naturales); concentrando la reflexión en un plano teórico (y cualitativo) sobre las energías renovables, consideradas la matriz energética del futuro. Se presenta una narrativa que exhibe una trayectoria intersticial alrededor de esa matriz. Si bien resulta predominante la apropiación capitalista, que cierta vertiente del pensamiento económico asume como uno de los ejes de la formación de la sexta onda larga de Kondratieff, también existen prácticas colectivas constitutivas del circuito de la economía social y solidario (ESS) que contribuyen a dislocar aquella formación capitalista.

Este artículo presenta el concepto de circuito económico del capital, que remonta a Karl Marx, y de circuito económico solidario, que remonta a dos décadas de nuestra elaboración — siendo retomados aspectos de las publicaciones que realizamos entre 1999 y 2008, anteriores a publicación de Circuiti economici solidali [Roma: Pioda, 2017]—. El artículo analiza cómo el valor económico circula entre ambos circuitos, pudiendo ser determinado como valor-capital o como valor-solidario. Y presenta, en clave de economía de liberación, algunos elementos de la estrategia de organización de circuitos económicos solidarios para la liberación de fuerzas económicas y organización de sociedades poscapitalistas.

Eimeria is a genus of apicomplexan parasites that infected various species and known as the enteric monoxenous coccidian. This study aims to determine the prevalence, identification and geographical distribution study of gastrointestinal protozoa Eimeria spp. in wild rodents in Malang city, East Java. A total of 74 rodents were collected from different part of Malang, using single live traps. Rats were euthanized with ketamine and xylazine. Samples of stools were taken from gastrointestinal tract. Coprological procedure using floatation method lead to the demonstration of Eimeria spp. oocysts in the faecal samples examined at 400 and 1000 magnifications of light microscope. Cultivation in dichromate potassium 2.5% was carried out for all of coccidian positive samples. The identification is based on morphology and morphometry. Eimeria identification data was analyzed descriptively, while the analysis of species and gender of rodents on prevalence used chi square. Result, the prevalence of Eimeria spp. in Malang is 11 (14.9%). It was suggesting coccidiosis caused by Eimeria nieschulzi. In addition, Chi square analysis showed that species of rats did not have a significant relationship (P>0.05) to the incidence of Eimeria infection, however it has significant correlation between gender of rats and Eimeria infection (P<0.05). The geographical of Eimeria spp. spots were showed in 8 Sampling area, in Lowokwaru, Klojen, Kedung kandang and Sukun sub district. Findings of this study showed that wild rodents in Malang city are infected with intestinal coccidian parasites.

Three-layer perceptron (TLP) is one of the approaches to the behavioral modeling of radio frequency (RF) power amplifiers (PAs) for wireless communication systems. A low-pass equivalent PA behavioral modeling should be able to represent the AM-AM and AM-PM characteristic curves, besides generating only useful contributions. This work shows that adapting a complex-valued activation function toencompass the strict characteristics from the AM-AM and AM-PM curves at the same time fulfilling the bandpass constraint gives better results in terms of network complexity and accuracy. Besides that, a novel TLP-based model for a multimode PA is proposed. This type of PA has characteristics that add difficulty to its inverse modeling. A modification in the ascendant method is also proposed for application with TLP-based PA models. This method simplifies the models in terms of operations needed for implementation. In a scenario of same number of network parameters, a significant reduction in modeling error is achieved when a complex-valued TLP that accounts for both AM-AM and AM-PM is used instead of a complex-valued TLP that accounts only for AM-AM. Such reduction is quantified by up to 5.73 dB (-35.53 dB to -41.26 dB) improvements in normalized mean square error (NMSE) metric. Moreover, when applying the ascendant method a 67% reduction in active parameters is achieved (36 to 12 active parameters), deteriorating the NMSE by less than 0.5 dB.
Logic Synthesis for Emerging Technologies

Published: May 2021

Emerging technologies are being considered to replace the conventional CMOS-based design that seems arriving to its end of life due to the limits of MOS transistor shrinking. However, since those novel devices are not necessarily switch-based ones, the traditional AND/OR logic synthesis process in the digital integrated circuit design flow tends to become inefficient, whereas threshold logic paradigm seems to be more appropriate for them. In this context, different methods for threshold logic synthesis, suitable for emerging technologies, are reviewed in this paper. The majority logic based design is also discussed herein since it represents a subset of threshold logic domain, and many new technologies have presented the 3-input majority Boolean function as the most basic logic gate. Experimental data, presented in previous works, are used to illustrate and compare the performance of the state-ofthe-art       logic synthesis methods related to

Tuberkulosis (TB) merupakan penyakit infeksi yang menempati peringkat utama penyebab kematian di dunia. Indonesia berada pada peringkat ke-3 dari 30 negara yang memiliki kasus TB terbanyak. Diabetes melitus (DM) tipe 2 merupakan salah satu faktor risiko terjadi TB. Paparan hiperglikemi pada pasien DM tipe 2 dapat memengaruhi sistem imun hingga lebih rentan menderita TB. Penelitian ini bertujuan menganalisis hubungan gula darah sewaktu pada saat pertama didiagnosis  DM tipe 2 dengan kejadian TB paru pada pasien DM tipe 2 di RSUD Al-Ihsan Bandung. Penelitian ini merupakan penelitian observasional analitik dengan pendekatan kasus kontrol. Kelompok kasus berjumlah 34 orang pasien DM tipe 2 yang mengalami TB, sedangkan kelompok kontrol berjumlah 59 pasien DM tipe 2 tanpa TB. Data penelitian merupakan data sekunder yang berasal dari rekam medis pasien. Pengumpulan dan pengolahan data diambil sesuai dengan kriteria inklusi dan eksklusi. Hasil penelitian terhadap 93 orang subjek di RSUD Al-Ihsan menunjuk bahwa pasien yang memiliki hiperglikemia berjumlah 19 pasien (56%) pada kelompok kasus dan 35 pasien (59%) pada kelompok kontrol. Hasil uji chi square didapatkan bahwa nilai p adalah 0,746 (p > 0,05) dengan alpha 5% (0,05), odd ratio sebesar 0,868.  Berdasar atas hasil uji analitik terhadap data penelitian dapat disimpulkan bahwa gula darah sewaktu pada pasien DM tipe 2 belum dapat menilai kemungkinan terjadi kejadian TB. Random Blood Sugar Unable to Predict the Incidence of TB in Type 2 DM PatientsTuberculosis (TB) the world’s leading cause of death from a single infectious disease. Indonesia is ranked 3rd out of the 30 countries with the most TB cases. Hyperglycemic exposure in type 2 DM patients can affect the immune system, making it more susceptible to TB. This study aims to look at the relationship of random blood sugar levels at the first time patient diagnosed as type 2 DM in pulmonary TB patients with type 2 DM at Al-Ihsan Hospital Bandung.

O modelo eclesiológico da Esposa de Cristo e o Documento de Santo Domingo
Authors: Bucker Bárbara Pataro
Published: May 2021

Neste artigo queremos falar da importância da Eclesiologia da Esposa na relação específica com a pastoral. Por um lado, a importância teórica da Eclesiologia mesma ajuda a orientar a pastoral; por outro - seguindo uma ideia muito íntima para a teologia latino-americana da libertação - a teologia é um ato segundo da vida da Igreja, e portanto nasce já de um processo histórico e vital. Por isso uma Eclesiologia do feminino na Igreja seria impensável se não tivesse existido primeiro um vigoroso movimento feminino na história, na pastoral e na teologia. Partindo de experiências tão concretas como o feminino da maternidade nas comunidades Eclesiais de Base (CEBs), é possível, entre outros fatos, descobrir este aspecto do feminino na Igreja...
