description: Groundwater supply in the Ogallala Aquifer is diminishing at an unsustainable rate, which is affecting the crop and animal production in the region. The desired future condition adopted by the North Plains Groundwater Conservation District states that at least 40% of the volume of groundwater should remain in the Ogallala Aquifer after 50 years in Dallam, Sherman, Hartley, and Moore counties. The main objective of this study is to evaluate the effects of 3 proposed groundwater management policies on future groundwater levels using a calibrated MODFLOW model. The 3 groundwater management policies considered are permanent conversion of 10% of the total irrigated area to dryland production, temporary conversion of 10% of the total irrigated area to dryland production for the first 15 years, and adoption of advances in biotechnology that allow groundwater use reductions at a rate of 1% per year during the next 50 years. Results indicated that if future average groundwater pumping rates are kept at 2010 withdrawal rates, then 50% of groundwater in the Ogallala Aquifer would remain in 50 years, thus meeting the groundwater district's desired future condition in Dallam, Sherman, Hartley and Moore counties. The most favorable impact on diminishing depletion was obtained with the adoption of advances in biotechnology, which would leave 60% of groundwater remaining in 50 years in the study area. Similar results can be obtained if 1% of irrigated cropland is retired per year.

description: Municipalities continue to implement efforts to encourage water conservation among residents. Landscape irrigation has been central to many of those conservation efforts. Reference evapotranspiration data is a tool that can be used in determining the appropriate amount of water to apply to amenity landscapes. Monthly water-use data for 3 years was examined in 1 neighborhood in Huntsville, Texas. The irrigated area for 1,229 residents was calculated and used to determine the depth of monthly irrigation for each residence. Replacement of 100% of local reference evapotranspiration data, minus rainfall, was used as a determinant of how much water to apply to the landscape each month for 3 years. Potential over-irrigation for each month was then compiled. Data expressed that over-irrigation was occurring among 99.51% of residents, of which 12% of these residents over-irrigated by at least 100,000 gallons in at least 1 month during the 36 month study. In 2011, the entire neighborhood of study over-irrigated by 21.2 million gallons. Outdoor water use accounted for 64% of the total water use by households. Average indoor water usage was 4,302 gallons per month. Based on the data overall, greater conservation efforts in landscape irrigation are crucial for Texas residents if water demands are to be met in the 21st century.

A New View of the Size-Mass Distribution of Galaxies: Using $r_{20}$ and $r_{80}$ instead of $r_{50}$

description: When investigating the sizes of galaxies it is standard practice to use the half-light radius, $r_{50}$. Here we explore the effects of the size definition on the distribution of galaxies in the size -- stellar mass plane. Specifically, we consider $r_{20}$ and $r_{80}$, the radii that contain 20% and 80% of a galaxy's total luminosity, as determined from a Sersic profile fit, for galaxies in the 3D-HST/CANDELS and COSMOS-DASH surveys. These radii are calculated from size catalogs based on a simple calculation assuming a Sersic profile. We find that the size-mass distributions for $r_{20}$ and $r_{80}$ are markedly different from each other and also from the canonical $r_{50}$ distribution. The most striking difference is in the relative sizes of star forming and quiescent galaxies at fixed stellar mass. Whereas quiescent galaxies are smaller than star forming galaxies in $r_{50}$, this difference nearly vanishes for $r_{80}$. By contrast, the distance between the two populations increases for $r_{20}$. Considering all galaxies in a given stellar mass and redshift bin we detect a significant bimodality in the distribution of $r_{20}$, with one peak corresponding to star forming galaxies and the other to quiescent galaxies. We suggest that different measures of the size are tracing different physical processes within galaxies; $r_{20}$ is closely related to processes controlling the star formation rate of galaxies and $r_{80}$ may be sensitive to accretion processes and the relation of galaxies with their halos.

description: Quantum string, which was brought into discussion recently as a model for the stripe phase in doped cuprates, is simulated by means of the density-matrix-renormalization-group method. String collides with adjacent neighbors, as it wonders, owing to quantum zero-point fluctuations. The energy cost due to the collisions is our main concern. Embedding a quantum string between rigid walls with separation d, we found that for sufficiently large d, collision-induced energy cost obeys the formula \sim exp (- A d^alpha) with alpha=0.808(1), and string's mean fluctuation width grows logarithmically \sim log d. Those results are not understood in terms of conventional picture that the string is `disordered,' and only the short-wave-length fluctuations contribute to collisions. Rather, our results support a recent proposal that owing to collisions, short-wave-length fluctuations are suppressed, but instead, long-wave-length fluctuations become significant. This mechanism would be responsible for stabilizing the stripe phase.

description: Exosomes, small extracellular vesicles of endocytic origin, have emerged as pivotal mediators in intercellular communication, driving transformative advancements across diverse fields of biology and medicine. This comprehensive review delves into the multifaceted roles of exosomes in health and disease, elucidating their biogenesis, cargo composition, and far-reaching implications. Exosomes, secreted by virtually all cell types, encapsulate a cargo comprising proteins, lipids, and nucleic acids, reflecting their cellular origin. Their molecular cargo modulates cellular processes, facilitating complex signalling cascades and contributing to the pathogenesis of various diseases, including cancer, neurodegenerative disorders, and infectious diseases. In cancer, exosomes serve as messengers of tumorigenesis and metastasis, orchestrating critical events within the tumor micro environment. Furthermore, exosomes participate in drug resistance mechanisms, presenting significant challenges in cancer therapy. The diagnostic potential of exosomes, particularly in the context of liquid biopsy, is underscored by their presence in various biofluids. This offers non-invasive disease monitoring and biomarker discovery, revolutionizing early detection and monitoring strategies. Additionally, exosomes have gained recognition as therapeutic vehicles, holding promise for targeted drug delivery, immunomodulation, and regenerative medicine. This review comprehensively explores the ever-expanding landscape of exosome biology, emphasizing their roles in health and disease. It underscores the transformative potential of exosomes in liquid biopsy-based diagnostics and therapeutics while acknowledging the complexities and challenges that lie ahead in harnessing their full clinical utility.

description: This paper tackles the problem of finding the optimal non-coherent detector for the reacquisition of weak Global Navigation Satellite System (GNSS) signals in the presence of bits and phase uncertainty. Two solutions are derived based on using two detection frameworks: the Bayesian approach and the generalized likelihood ratio test (GLRT). We also derive approximate detectors of reduced computation complexity and without noticeable performance degradation. Simulation results reveal a clear improvement of the detection probability for the proposed techniques with respect to the conventional detectors implemented in high sensitivity GNSS (HS-GNSS) receivers to acquire weak GNSS signals. Finally, we draw conclusions on which is the best technique to reacquire weak GNSS signals in practice considering a trade-off between performance and complexity.

We show that the amplitude of the fluctuations reaches maximum at a partially opened channel, G\lesssim e^2/π\hbar. Parametric correlations of fluctuations at different values of the applied voltage and magnetic field can be studied experimentally, and we find the corresponding correlation functions for the differential capacitance.

description: A Animação Sociocultural, tem desde o início do Sec. XX afirmado o seu papel no quotidiano, sendo utilizada na gíria comum e com um papel cada vez mais presente em inúmeros contextos. Para sustentar a sua prática, encontra- se regulada por elementos normativos como o estatuto do animador sociocultural e o código deontológico do animador. Infelizmente, a prática de animação sociocultural, não é legislada por nenhum tipo de ordem, ao contrário de uma enormidade de outras profissões. O objetivo deste artigo, além de dar a conhecer o que é a animação sociocultural, pretende informar que a prática de atividades levadas a cabo pelos animadores deve ser sustentada em elementos normativos, numa ótica de promoção das relações entre pares e numa base de prática reflexiva. Esta prática reflexiva, pretende que o animador seja capaz de analisar as suas ações, perspectivando o que correu bem e menos bem, tendo em conta o seu público, meio e atividade.

description: Nearly all young stars are initially surrounded by `protoplanetary' discs of gas and dust, and in the case of single stars at least 30\% of these discs go on to form planets. The process of protoplanetary disc formation can result in initial misalignments, where the disc orbital plane is different to the stellar equator in single star systems, or to the binary orbital plane in systems with two stars. A quirk of the dynamics means that initially misaligned `circumbinary' discs -- those that surround two stars -- are predicted to evolve to one of two possible stable configurations, one where the disc and binary orbital planes are coplanar, and one where they are perpendicular (a `polar' configuration). Prior work has found coplanar circumbinary discs, but no polar examples were known until now. Here we report the first discovery of a protoplanetary circumbinary disc in the polar configuration, supporting the predictions that such discs should exist. The disc shows some characteristics that are similar to discs around single stars, and that are attributed to dust growth. Thus, the first stages of planet formation appear able to proceed in polar circumbinary discs.

description: Single-loop methods for reliability-based design optimization are characterized by high computational efficiency. However, the accuracy of these methods may be low for highly nonlinear probabilistic constraints. A new hybrid method called ‘SLShV-CG’ is proposed for improving accuracy in which the single-loop method is coupled with the shifting vector approach of the sequential optimization and reliability assessment method. This shifting vector approach is incorporated with the probabilistic constraints without approximating them for reliability analysis. The most probable points for the probabilistic constraints are found using the Karush–Kuhn–Tucker conditions and the conjugate gradient search direction is used for determining the approximate most probable point in every iteration. The proposed method is tested on four mathematical and four engineering reliability-based design optimization problems, and the accuracy of the solutions is verified using Monte Carlo simulations. The results demonstrate the better accuracy and computational efficiency of the proposed method over six reliability-based design optimization methods from the literature.

description: We analyze the cosmology of the Randall-Sundrum model and that of compact brane models in general in the presence of a radius stabilization mechanism. We find that the expansion of our universe is generically in agreement with the expected effective four dimensional description. The constraint (which is responsible for the appearance of non-conventional cosmologies in these models) that must be imposed on the matter densities on the two branes in the theory without a stabilized radius is a consequence of requiring a static solution even in the absence of stabilization. Such constraints disappear in the presence of a stablizing potential, and the ordinary FRW (Friedmann-Robertson-Walker) equations are reproduced, with the expansion driven by the sum of the physical values of the energy densities on the two branes and in the bulk. For the case of the Randall-Sundrum model we examine the kinematics of the radion field, and find that corrections to the standard FRW equations are small for temperatures below the weak scale. We find that the radion field has renormalizable and unsuppressed couplings to Standard Model particles after electroweak symmetry breaking. These couplings may have important implications for collider searches. We comment on the possibility that matter off the TeV brane could serve as a dark matter candidate.

description: With the mobile technology widespread, new functionalities are being integrated in devices, namely augmented reality (AR), which can be used to enhance learning. Combining mobile AR learning with game-based approaches supports new forms of instruction in the outdoors and students’ engagement and motivation for learning are enhanced. However, new practices require teacher training. This is the case of the EduPARK workshop that aims to support teachers in the development of innovative outdoor practices, using mobile devices, AR and games. In this exploratory case study, qualitative and quantitative data were collected from five editions of the EduPARK workshop through a mandatory questionnaire and a voluntary reflexive self-account. Results show that teachers value this training for: i) the access to new educational resources, ii) the practices changing support, iii) knowledge update, although not necessarily in what concerns mobile learning, AR and game-based approaches, and iv) learning about cross-subjects approaches to teaching.

description: Polarimetric interferometry is a method allowing the study of the distribution of polarized flux at diffraction-limited resolution. Its basic observable is the ratio $\mathcal{R}$ of the visibilities of the object in two orthogonal polarizations. Here, we demonstrate how this observables can be measured with the SPeckle Polarimeter (SPP) of the 2.5-m telescope. The SPP is a combination of a dual-beam polarimeter and an EMCCD-based visible-range speckle interferometer. We propose a simple method for the correction of $\mathcal{R}$ for the instrumental polarization and polarization differential aberrations of the telescope. The polarized intensity image can be estimated from $\mathcal{R}$ under the assumption that the object is a point-like unpolarized source plus a faint extended polarized envelope. The phase of $\mathcal{R}$ can be used for measurement of the polaroastrometric signal - the difference between the photocentres of orthogonally polarized images of the object. We investigate both possibilities using observations of unpolarized stars and stars with a significant polarized circumstellar environment - $μ$~Cep and RY~Tau.

description: Background Few studies have examined epigenetic age acceleration (AA), the diference between DNA methylation (DNAm) predicted age and chronological age, in relation to somatic genomic features in paired cancer and normal tissue, with less work done in non-European populations. In this study, we aimed to examine DNAm age and its associations with breast cancer risk factors, subtypes, somatic genomic profles including mutation and copy number alterations and other aging markers in breast tissue of Chinese breast cancer (BC) patients from Hong Kong.
Methods We performed genome-wide DNA methylation profling of 196 tumor and 188 paired adjacent normal tissue collected from Chinese BC patients in Hong Kong (HKBC) using Illumina MethylationEPIC array. The DNAm age was calculated using Horvath’s pan-tissue clock model. Somatic genomic features were based on data from RNA sequencing (RNASeq), whole-exome sequencing (WES), and whole-genome sequencing (WGS). Pearson’s correlation (r), Kruskal–Wallis test, and regression models were used to estimate associations of DNAm AA with somatic features and breast cancer risk factors.
Results DNAm age showed a stronger correlation with chronological age in normal (Pearson r=0.78, P<2.2e−16) than in tumor tissue (Pearson r=0.31, P=7.8e−06). Although overall DNAm age or AA did not vary signifcantly by tissue within the same individual, luminal A tumors exhibited increased DNAm AA (P=0.004) while HER2-enriched/basal-like tumors exhibited markedly lower DNAm AA (P=<.0001) compared with paired normal tissue. Consistent with the subtype association, tumor DNAm AA was positively correlated with ESR1 (Pearson r=0.39, P=6.3e−06) and PGR (Pearson r=0.36, P=2.4e−05) gene expression. In line with this, we found that increasing DNAm AA was associated with higher body mass index (P=0.039) and earlier age at menarche (P=0.035), factors that are related to cumulative exposure to estrogen. In contrast, variables indicating extensive genomic instability, such as TP53 somatic mutations, high tumor mutation/copy number alteration burden, and homologous repair defciency were associated with lower DNAm AA.

description: The exponentially strong damping of the conventional Friedel oscillations at elevated temperature T as well as due to disorder poses a severe problem to the Hume-Rothery (HR) stabilization mechanism of amorphous and quasicrystalline alloys. We show that quantum correlations induced by electron-electron interactions in the presence of random impurity scattering can play an important role in stabilizing these systems: When there is strong backscattering off local ion clusters, the static electron density response chi(0,q) acquires a powerlaw divergence at q=2k_F even at T>0. This Fermi surface singularity leads to an enhancement as well as to a systematical phase shift of the Friedel oscillations, consistent with experiments. In addition, the spatial decay exponent is reduced, strongly supporting the validity of a HR-like mechanism at T>0. This effect may be accounted for in pseudopotential calculations through the local field factor.

description: We investigate the ground-state heavy quarkonium $χ_{c1}(1P)$ and its first excited state $χ_{c1}(2P)$ with quantum numbers $J^{PC}=1^{++}$. The masses and decay constants of these charmonium states are computed using two-point QCD sum rule method by including quark, gluon and mixed condensates up to dimension-8. We compare our numerical results with the available experimental data as well as existing theoretical predictions in the literature.

description: O presente artigo apresenta uma revisão dos estudos Tandem nacionais acerca da qualidade da interação e da comunicação de pais e educadores em atividades colaborativas com a criança em idade pré-escolar. Para o efeito, os resultados de todos os artigos publicados são organizados pelas seguintes áreas: autoria do produto; tipo de produto realizado; componentes, materiais e ferramentas usadas na realização do produto; qualidade interativa; comunicação verbal; fatores ligados à criança e fatores ligados ao adulto. Os dados ainda, exploratórios pela dimensão reduzida das amostras, indicam sobretudo que a forma como os Pais atuam é distinta dos Educadores. Igualmente, são encontradas diferenças de género, na medida em que são proporcionadas às meninas e aos meninos distintas oportunidades na realização das tarefas. O corpo de conhecimento acumulado permite compreender como a comunicação facilita e desencadeia a interrogação e a reflexão da criança, e de que forma a qualidade da interação a motiva para participar nesse espaço. Palavras-chave: Tarefas Colaborativas, Interação, Comunicação, Pais, Educadores

description: We introduce a method for producing a galaxy sample unbiased by surface brightness and stellar mass, by selecting star-forming galaxies via the positions of core-collapse supernovae (CCSNe). Whilst matching $\sim$2400 supernovae from the SDSS-II Supernova Survey to their host galaxies using IAC Stripe 82 legacy coadded imaging, we find $\sim$150 previously unidentified low surface brightness galaxies (LSBGs). Using a sub-sample of $\sim$900 CCSNe, we infer CCSN-rate and star-formation rate densities as a function of galaxy stellar mass, and the star-forming galaxy stellar mass function. Resultant star-forming galaxy number densities are found to increase following a power-law down to our low mass limit of $\sim10^{6.4}$ M$_{\odot}$ by a single Schechter function with a faint-end slope of $α= -1.41$. Number densities are consistent with those found by the EAGLE simulations invoking a $Λ$-CDM cosmology. Overcoming surface brightness and stellar mass biases is important for assessment of the sub-structure problem. In order to estimate galaxy stellar masses, a new code for the calculation of galaxy photometric redshifts, zMedIC, is also presented, and shown to be particularly useful for small samples of galaxies.

description: O objetivo do estudo foi elaborar e aplicar o Plano Educacional Individualizado (PEI) nas aulas de Educação Física em uma escola especial, como estratégia de inclusão e aprendizagem. A pesquisa partiu do seguinte problema: De que forma o PEI pode contribuir para a aprendizagem nas aulas de Educação Física? Assim, o PEI foi elaborado de forma colaborativa, conforme os pressupostos da pesquisa-ação colaborativa. As intervenções ocorreram no campo do estágio, em uma escola especial com uma aluna com deficiência física e intelectual. Focou-se na oratória e nos movimentos dos membros superiores. O conteúdo Dança sustentou a organização do PEI. Durante o período das intervenções notou-se melhoras significativas no desenvolvimento da aluna, especialmente na oratória mais desinibida, nos movimentos de locomoção e coordenação. Considera-se que o PEI mostrou-se como uma ferramenta positiva para o ensino da Educação Física no contexto da Educação Especial.

description: A hybrid orbit propagator based on the analytical integration of the Kepler problem is designed to determine the future position and velocity of any orbiter, usually an artificial satellite or space debris fragment, in two steps: an initial approximation generated by means of an integration method, followed by a forecast of its error, determined by a prediction technique that models and reproduces the missing dynamics. In this study we analyze the effect of slightly changing the initial conditions for which a hybrid propagator was developed. We explore the possibility of generating a new hybrid propagator from others previously developed for nearby initial conditions. We find that the interpolation of the parameters of the prediction technique, which in this case is an additive Holt-Winters method, yields similarly accurate results to a non-interpolated hybrid propagator when modeling the J2 effect in the main problem propagation.

Fuchsian analysis of singularities in Gowdy spacetimes beyond analyticity

description: Fuchsian equations provide a way of constructing large classes of spacetimes whose singularities can be described in detail. In some of the applications of this technique only the analytic case could be handled up to now. This paper develops a method of removing the undesirable hypothesis of analyticity. This is applied to the specific case of the Gowdy spacetimes in order to show that analogues of the results known in the analytic case hold in the smooth case. As far as possible the likely strengths and weaknesses of the method as applied to more general problems are displayed.

Clumpiness of the interstellar medium in the central parsec of the Galaxy from H2 flux extinction correlation

description: The central parsec of the Galaxy contains a young star cluster embedded in a complex interstellar medium. The latter mainly consists of a torus of dense clumps and streams of molecular gas (the circumnuclear disk, CND) enclosing streamers of ionized gas (the Minispiral). In this complex environment, knowledge of the local extinction that locally affects each feature is crucial to properly study and disentangle them. We previously studied molecular gas in this region and inferred an extinction map from two H2 lines. Extinction appears to be correlated with the dereddened flux in several contiguous areas in the field of view. Here, we discuss the origin of this local correlation. We model the observed effect with a simple radiative transfer model. H2 emission arises from the surfaces of clumps (i.e., shells) that are exposed to the ambient ultraviolet (UV) radiation field. We consider the shell at the surface of an emitting clump. The shell has a varying optical depth and a screen of dust in front of it. The optical depth varies from one line of sight to another, either because of varying extinction coefficient from the shell of one clump to that of another or because of a varying number of identical clumps on the line of sight. In both scenarios, the model accurately reproduces the dependence of molecular gas emission and extinction. The reason for this correlation is that, in the central parsec, the molecular gas is mixed everywhere with dust that locally affects the observed gas emission. In addition, there is extinction due to foreground (screen) dust. This analysis favors a scenario where the central parsec is filled with clumps of dust and molecular gas. Separating foreground from local extinction allows for a probe for local conditions (H2 is mixed with dust) and can also constrain the three-dimensional (3D) position of objects under study.

description: The polysaccharides were acquired from the seeds of T. sinensis by hot water extraction, ethanol precipitation, decoloration with macroporous 900 resin, and deproteinization with sevag reagent, which possessed significantly immunomodulatory activity on the levels of IgA, IgG, and IgM, the relative indices of thymus and spleen, and the phagocytosis index of mice in vivo. T. sinensis seeds polysaccharides (TSP) were separated and purified using DEAE-52 cellulose and Sephacryl S-300 column chromatography to obtain TSP-3a characterized of molecular weight, monosaccharides composition, and other preliminary structural features. TSP-3a (758.6 kDa) mainly contained Man, GalN, GlcA, Rha, Glc, Gal, Ara, and Fuc in a molar ratio of 0.26:0.24:0.19:1.80:0.45:12.56:1.09:0.21. FT-IR analysis suggested TSP-3a was an acid polysaccharide and the presence of β configuration within the TSP-3a was discovered. Combining 1H NMR, 13C NMR, and comparison with those reported in the literature, the backbone of TSP-3a might contain →6)-α-D-Glc-(1→, →3)-β-D-GlcA-(1→, →6)-α-D-Gal-(1→, α-D-Glc-(1→, and →6)-β-D-Gal-(1→.
