description: Numa altura em que o YouTube evoluiu de simples repositório de vídeos para uma plataforma com características de interação semelhantes a das redes sociais, é pertinente a questão de quão útil pode ser esta plataforma para a aprendizagem de Inglês como língua estrangeira. Partindo da análise qualitativa dos conteúdos presentes nos vídeos e nos comentários de 5 canais do YouTube, procurou-se compreender como este tem sido usado enquanto ferramenta de apoio na aprendizagem informal do Inglês. Para tal abordou-se o corpus de dados disponíveis nos variados canais da plataforma, dedicados ao ensino desta língua. Após tratamento dos dados no webQDA e uma análise dos dados, chegou-se a conclusões que sugerem que o YouTube é uma ferramenta apreciada por aprendentes dos níveis iniciais de aprendizagem de Inglês. Também foram identificados alguns itens a melhorar apresentados como sugestões aos produtores/criadores dos canais, de forma a tornar ferramentas mais úteis à aprendizagem informal de inglês.

description: Adherens junctions are intercellular and cell-matrix junctions that, like desmosomes and hemidesmosomes, mediate adhesion of cells to each other or to matrix structures. These junctions have been detected recently in cultured human keratinocytes, indicating that they may be of importance in epidermis. To investigate the localization of adherens junctions in normal epidermis, we examined human epidermis, human oral mucosa, and monkey esophagus for the presence of vinculin, a major protein of the intracellular plaques of adherens junctions that is thought to be present in all adherens junctions. 'Western blot analysis demonstrated vinculin in extracts of epidermis. Immunohistochemistry of vinculin in these tissues displayed two distinct locations for adherens junctions: i) at the dermal-epidermal junction, and ii) in the region of cell-cell contacts in all layers of the epidermis. The location of vinculin in the region of the epidermal-dermal junction is reminiscent of the distribution of vinculin-containing focal contacts in cultured keratinocytes, and the intercellular staining of vinculin in epidermis is consistent with the presence of vinculin in adherens junctions in cultured keratinocytes at sites of cell-cell contact. These results demonstrate that adherens junctions are present in human epidermis, oral mucosa, and monkey esophagus. Vinculin-containing junctions in epidermis may be important in the pathogenesis, of skin diseases involving alterations in intercellular integrity.

description: The microalga Spirulina platensis is recognized for its high nutritional value, particularly in terms of protein and bioactive compounds, and can be used to produce functional foods. The aim of this study was to develop a novel functional Ricotta cheese fortified with different amounts of spirulina powder (SRC) (0.25 , 0.5, 0.75, and 1.0) g/100 g cheese and to evaluate the effects on the cheese’s physicochemical, sensorial, and microbiological properties over a 21- day storage period at 5°C. Spirulina platensis had 70.4, 5.02, 6.77, 5.43, and 12.06 g/100 g (as drymatter) for protein, lipids, ash, fiber, and carbohydrate, respectively. It also had a high concentration of bioactive compounds, including 240.50 mg (as Gallic acid equivalents/100 g) of phenolic compounds and 30.79 mg/100 g of β-carotene. Ricotta cheese fortified with spirulina powder had a significant increase in protein, fat, ash, fibers, carbohydrates, and mineral contents. The total phenols, β-carotene, and 2,2-Diphenyl-1-picrylhydrazyl scavenging capacity of SRC also increased when compared with control. The textural properties of SRC cheese were improved, and it exhibited a more attractive color and desirable microstructure. The number of aerobic bacteria increased in SRC cheese, while no yeasts or mold were detected in all fresh cheese samples, but they appeared on the 14th day for the control sample and on the 21st day for the Ricotta cheese fortified with spirulina powder sample. Coliform bacterial cells were not observed in all fresh cheese or during storage. The addition of 0.75 g/100 g dry-solids SPP is found to be optimum in terms of color and other sensorial properties.

description: Some lessons learned from our work getting electricity system data into the hands of activists and researchers who are trying to shift power in US energy policy making. Under what circumstances can data help drive policy changes, and how does that change happen? Is open data always preferable in an advocacy context? What does it really mean for data to be accessible to advocates? US energy regulation is extremely technocratic, and largely happens out of public view. For years we’ve tried to address the information asymmetry that exists between advocates and large utilities by publishing cleaned open datasets detailing the inner workings of the US electricity system. We use Python data science tools to prepare the data and they serve us well, but most advocates -- even those with a lot of domain expertise -- are either hardcore spreadsheet users, or are just starting to dabble in Jupyter Notebooks. Now that we have a decent data pipeline, we are turning our attention to improving the data’s accessibility for our target users, using Datasette, Docker containers that run Jupyter, and Intake data catalogs.

description: It has been demonstrated that the difference between the Renormalised Brane World (RBW) model and the Lambda Cold Dark Matter ($Λ$CDM) model occurs only at sufficiently distant times. In this paper, it is shown that for spherically symmetric situations an analog deviation between the RBW model and Newton's theory occurs at large distances. More precisely, this deviation of the RBW model is nothing other than the explanation of Milgrom's hypothesis and follows from itself. Therefore, the results of this paper explains flat rotation curves of galaxies without dark matter.

description: We study all possible texture zeros in the Majorana neutrino mass matrix which are allowed from neutrino oscillation as well as cosmology data when the charged lepton mass matrix is assumed to take the diagonal form. In case of one-zero texture, we write down the Majorana phases which are assumed to be equal and the lightest neutrino mass as a function of the Dirac CP phase. In case of two-zero texture, we numerically evaluate all the three CP phases and lightest neutrino mass by solving four real constraint equations. We then constrain texture zero mass matrices from the requirement of producing correct baryon asymmetry through the mechanism of leptogenesis. Adopting a type I seesaw framework, we consider the CP violating out of equilibrium decay of the lightest right handed neutrino as the source of lepton asymmetry. Apart from discriminating between the texture zero mass matrices and light neutrino mass hierarchy, we also constrain the Dirac and Majorana CP phases so that the observed baryon asymmetry can be produced. In two-zero texture, we further constrain the diagonal form of Dirac neutrino mass matrix from the requirement of producing correct baryon asymmetry.

É neste paradigma que os Blogs Escolares surgem como um meio para o reforço e promoção da aprendizagem dos alunos. Dessa forma, este artigo, que tem por base metodológica o estudo de caso em relação à analise de 12 Blogs Escolares de uma rede educacional particular do Brasil, procura averiguar se os posts publicados nestes Blogs Escolares poderiam proporcionar e potenciar ambientes propícios à aprendizagem ativa. Os 12 blogs analisados correspondem a diversas disciplinas do 1º e 2º nível de ensino do Brasil. A análise aos 221 posts e respetivos comentários destes Blogs Escolares permitiu aferir que os mesmos não estão a ser usados para a promoção de ambientes de aprendizagem ativa, revelando na sua grande maioria uma evidente preferência pela aprendizagem passiva.

The anisotropic fluid solution so obtained join continuously to Schwarzschild exterior solution across the pressure free boundary. It is observed that most of the new anisotropic solutions are well behaved and utilized to construct the super-dense star models such as neutron star and pulsars.

description: The low-energy effective Hamiltonian of the strong `spin'-orbit coupled one-dimensional hole gas in a cylindrical Ge nanowire in the presence of a strong magnetic field is studied both numerically and analytically. Basing on the Luttinger-Kohn Hamiltonian in the spherical approximation, we show this strong `spin'-orbit coupled one-dimensional hole gas can be accurately described by an effective two-band Hamiltonian $H^{\rm ef}=\hbar^{2}k^{2}_{z}/(2m^{*}_{h})+ασ^{x}k_{z}+g^{*}_{h}μ_{B}Bσ^{z}/2$, as long as the magnetic field is purely longitudinal or purely transverse. The explicit magnetic field dependent expressions of the `spin'-orbit coupling $α\equivα(B)$ and the effective $g$-factor $g^{*}_{h}\equiv\,g^{*}_{h}(B)$ are given. When the magnetic field is applied in an arbitrary direction, the two-band Hamiltonian description is still a good approximation.

description: Obesity is one of the major causes of non-communicable diseases (NCDs) associated with a dietary pattern rich in saturated fat. The present study utilized roasted and germinated chickpeas (Cicer arietinum) flour (RCPF and GCPF) as a replacement for fat in biscuits, known to have nutraceutical properties. The fat content was modified using the following ratios: 10%, 20%, and 30% (w/w) of RCPF/GCPF. Based on the physicochemical analysis, increased concentrations of RCPF and GCPF in the flour blends resulted in higher levels of protein, ash, and crude fiber contents. GCPF was found to contain higher levels of protein (20.20%), ash (4.86%), and crude fiber (3.64%) compared to RCPF. Increased RCPF and GCPF levels resulted in reduction of gluten content, which indicated weak gluten network. Scanning electron micrographs (SEM) of biscuit samples further supported these observations. The farinograph properties showed significant increase (P<0.05) in water absorption and dough development time. Furthermore, when RCPF and GCPF were added to flour blends and biscuits samples, significant increase (P<0.05) in antioxidant activity, total phenolic content, and total flavonoid content was observed. These trends were observed to be more prominent with higher quantities of RCPF and GCPF. Notably, the antioxidant properties of chickpeas were found to be significantly improved (P<0.05) by the process of germination compared to roasting. Moreover, improvements in antioxidant activity might be caused by the increased levels of phenolic compounds and ascorbic acid due to the actions of endogenous hydrolytic enzymes during germination. The dimensional, textural, and sensory properties indicated that RCPF 20% and GCPF 10% can effectively serve as an organic fat substitute in bakery products with enhanced concentrations of proteins, fibers, antioxidants, and bioactive compounds with nutraceutical properties.

description: Autoantibodies to type VII collagen are characteristic of the blistering diseases epidermolysis bullosa acquisita and bullous systemic lupus erythematosus (SLE). Blisters in those diseases are due to defective adhesion of the lamina densa subregion of the epithelial basement membrane to the underlying dermis. Previous studies indicating that type VII collagen contributes to lamina densa-dermal adhesion by cross-linking lamina densa and dermal matrix proteins suggests that autoantibodies may contribute to blisters by interfering with type VII collagen function. That hypothesis is supported by previous studies showing autoantibodies from a small number of epidermolysis bullosa acquisita patients recognize proteolytic fragments containing the 145-kD noncollagenous domain of type VII collagen. In this study, we examined reactivity of autoantibodies from a large number of epidermolysis bullosa acquisita and bullous SLE patients with fusion proteins representing most of the noncollagenous domain of type VII collagen and that those regions are homologous to type III repeats of fibronectin. These results suggest autoantibodies binding to fibronectin homology regions within the 145-kD noncollagenous domain may interfere with the adhesion function of type VII collagen and contribute to lamina densa-dermal dysadhesion in epidermolysis bullous acquisita and bullous SLE.

description: In-situ, two-dimensional (2D) Langmuir probe measurements across a large part of the TCV divertor are reported in L-mode discharges with and without divertor baffles. This provides detailed insights into time averaged profiles, particle fluxes, and fluctuations behavior in different divertor regimes. The presence of the baffles is shown to substantially increase the divertor neutral pressure for a given upstream density and to facilitate the access to detachment, an effect that increases with plasma current. The detailed, 2D probe measurements allow for a divertor particle balance, including ion flux contributions from parallel flows and ExB drifts. The poloidal flux contribution from the latter is often comparable or even larger than the former, such that the divertor parallel flow direction reverses in some conditions, pointing away from the target. In most conditions, the integrated particle flux at the outer target can be predominantly ascribed to ionization along the outer divertor leg, consistent with a closed-box approximation of the divertor. The exception is a strongly detached divertor, achieved here only with baffles, where the total poloidal ion flux even decreases towards the outer target, indicative of significant plasma recombination. The most striking observation from relative density fluctuation measurements along the outer divertor leg is the transition from poloidally uniform fluctuation levels in attached conditions to fluctuations strongly peaking near the X-point when approaching detachment.

description: The neutron-proton effective mass splitting in neutron-rich nucleonic matter reflects the space-time nonlocality of the isovector nuclear interaction. It affects the neutron/proton ratio during the earlier evolution of the Universe, cooling of protoneutron stars, structure of rare isotopes and dynamics of heavy-ion collisions. While there is still no consensus on whether the neutron-proton effective mass splitting is negative, zero or positive and how it depends on the density as well as the isospin-asymmetry of the medium, significant progress has been made in recent yeas in addressing these issues. We first recall the connections among the neutron-proton effective mass splitting, the momentum dependence of the isovector potential and the density dependence of the symmetry energy. We then make a few observations about the progress in calculating the neutron-proton effective mass splitting using various nuclear many-body theories and its effects on the isospin-dependence of in-medium nucleon-nucleon cross sections. Perhaps, our most reliable knowledge so far about the neutron-proton effective mass splitting at saturation density of nuclear matter comes from optical model analyses of huge sets of nucleon-nucleus scattering data accumulated over the last five decades. The momentum dependence of the symmetry potential from these analyses provide a useful boundary condition at saturation density for calibrating nuclear many-body calculations. Several observables in heavy-ion collisions have been identified as sensitive probes of the neutron-proton effective mass splitting in dense neutron-rich matter based on transport model simulations. We review these observables and comment on the latest experimental findings.

description: Oat (Avena sativa) is a cereal crop rich in dietary fibers, which are generally considered beneficial for human health. The objective of this work was to investigate the in vitro starch digestibility-reducing effect of the flour of a high arabinoxylan (AX) content (6.1%) oat line obtained from a random mutagenized oat population, compared to the original variety as a reference. The effect of the oat flours was tested on gelatinized potato starch as a dietary starch model, using a digestion dialysis method to calculate the predicted Glycaemic Index (pGI). The high AX flour reduced the potato starch pGI to larger extent than the flour from the original line. The pGI-lowering effect of the AX in the mutant line was confirmed by its attenuation following pre-treatment of the flour with xylanase. The larger pGI-lowering effect of the high AX oat line suggested this type of mutant as a potential functional food/ingredient for better management of postprandial glycemic responses.

description: Os resultados do desempenho dos estudantes portugueses no Programme for Internacional Student Assessment (PISA) têm sido alvo de inúmeras discussões na Blogosfera. O nosso interesse por estas discussões levaram-nos ao desenvolvimento do presente estudo, que teve por objetivo conhecer os fatores influenciadores dos resultados de Portugal nas edições do PISA, de 2000 a 2012, de acordo com posts e comentários de blogues. O referencial teórico englobou vários aspectos e evidências ligadas ao PISA, bem como uma breve contextualização do currículo em Portugal e da Blogosfera. O estudo foi desenvolvido com base na abordagem qualitativa, do tipo exploratório-descritivo, tendo como fonte dos dados dez blogues portugueses. Os dados consistiram em trinta e cinco posts com respectivos comentários, num total de cento e dezoito. Foram analisados através da análise de conteúdo, com o apoio do programa de análise qualitativa WebQDA. Os resultados apontaram três fatores influenciadores do desempenho dos estudantes portugueses no PISA: Ensino, Amostragem e Retenção/Reprovação. Dentre os resultados no fator Ensino é de salientar as discussões em torno do impacto do ensino privado e público e das condições socioeconómicas das famílias/estudantes nos resultados do PISA, e das mudanças políticas em curso, com possíveis ameaças à qualidade do ensino. Os critérios da definição da população de estudantes e consequente seleção da amostra foi considerado pouco efetivo, devido às variações ao longo das edições, o que dificulta a comparação dos resultados do PISA. A Retenção/Reprovação foi considerada uma medida pedagógica pouco eficaz, com impacto negativo nos resultados do PISA. Estes resultados foram apoiados pela literatura. Com este estudo, esperamos contribuir para ampliar o conhecimento e criar novos espaços para futuras discussões e investigações na área.

description: Trichohyalin is a major differentiation product of hard keratinizing tissues such as the inner root sheath and medullary cells of the hair follicle and the filiform papillae of the tongue, as well as terminally differentiating epidermal cells. It consists largely of quasi-repeating peptide repeats and functions primarily as an intermediate filament-associated protein in these tissues. By mapping with human-rodent somatic cell hybrids and fluorescent in situ hybridization, we demonstrate that its gene maps to chromosomal region 1q21. Interestingly, genes encoding several other structural proteins expressed during terminal differentiation in the epidermis map to this region, as do also several members of the S-100 class of small calcium-binding proteins.

To determine the temporal relationship of this unique immunohistochemical defect with course of clinical disease activity, we have longitudinally studied the expression of two epitopes of type VII collagen (LH 7:2; L3d) in nine patients in four such kindreds by immunofluorescence and immunoelectron microscopic technique. In every infant so studied at the time of active blistering, type VII collagen was detectable primarily within basilar and, to a lesser extent, suprabasilar keratinocytes. In contrast, type VII collagen was detectable solely in linear array along the dermoepidermal junction in skin from each patient following complete cessation or at least marked diminution of visible clinical disease activity. These findings support the hypothesis that the temporary mechanical fragility and blistering of the skin in infants with this rare subset of dominant dystrophic epidermolysis bullosa reflect the presence of reduced amounts of type VII collagen along the dermoepidermal junction, and that this diminution may be the result of either a delay in transport and integration of type VII collagen from basilar keratinocytes into the skin basement membrane or excessive phagocytosis of type VII collagen.

description: The bulk-edge correspondence (BEC) is the hallmark of topological systems. In continuous (nonlattice) Hermitian systems with an unbounded wave vector, it was recently shown that the BEC of Chern insulators is modified. How would it be further affected in non-Hermitian systems, experiencing loss and/or gain? In this work, we take the first step in this direction, by studying a bulk-Hermitian continuous system with non-Hermitian boundary conditions. We find in this case that edge modes emerge at the roots of the scattering matrix, as opposed to the Hermitian case, where they emerge at its poles (or, more accurately, coalescence of roots and poles). This entails a nontrivial modification to the relative Levinson's theorem. We then show that the topological structure remains the same as in the Hermitian case, and the generalized BEC holds, provided one employs appropriately modified contours in the wave-vector plane so that the scattering matrix phase winding counts the edge modes correctly. We exemplify all this using a paradigmatic model of waves in a shallow ocean or active systems in the presence of odd viscosity, as well as 2D electron gas with Hall viscosity. We use this opportunity to examine the case of large odd viscosity, where the scattering matrix becomes $2\times2$, which has not been discussed in previous works on the Hermitian generalized BEC.

description: On the cytoplasmic side of the plasma membrane of erythrocytes there is a dense protein filament matrix that maintains the shape of the cells. The main constituents of this system, actin and spectrin, which have also been detected in keratinocytes and fibroblasts, are known to be linked in erythrocytes in a network structure by additional proteins such as band 4.1 and adducin. The interaction between actin and spectrin, mediated by adducin, is regulated by calmodulin and protein kinase C. Because we have previously found adducin in cultured keratinocytes, we investigated epidermis by immunochemical techniques. We found adducin to be localized at cell-cell contact sites in epidermis using affinity-purified antibodies against human erythrocyte adducin. Immunofluorescence of epidermis revealed an intense fluorescence in the basal layer, whereas stratum spinosum and stratum granulosum showed moderate staining. There was intense staining at sites of cell-cell contact in cultured human keratinocytes. Immunoblot analysis indicated the presence of adducin polypeptides of 103 kd and 97 kd in epidermis, but in cultured keratinocytes only the higher molecular weight form could be detected. This study indicates adducin, a regulatory protein in erythrocytes, is also present in epidermis. Its localization suggests that it may be involved in the formation of the microfilament matrix of the membrane skeleton at cell-cell contact sites.

description: Yau proved an existence theorem for Ricci-flat Kähler metrics in the 1970's, but we still have no closed form expressions for them. Nevertheless there are several ways to get approximate expressions, both numerical and analytical. We survey some of this work and explain how it can be used to obtain physical predictions from superstring theory.

Normal Molecular Weight of Type VII Collagen Produced by Recessive Dystrophic Epidermolysis Bullosa Keratinocytes

description: Studies of the recessive dystrophic form of epidermolysis bullosa (RDEB) have suggested that an abnormality in type VII collagen may be involved in the pathogenesis of this disorder. Indirect immunofluorescence studies have shown that the staining for type VII collagen along the dermal-epidermal junction is markedly reduced or absent in all but rare cases of severe, generalized RDEB. These findings imply that the genetic defect may involve type VII collagen but do not exclude the possibility that the alterations demonstrated are secondary, for example, to nonspecific proteolysis of type VII collagen. To evaluate the ability of cells of affected patients to produce type VII collagen, we cultured keratinocytes from a severely affected patient and immunoprecipitated type VII collagen from the cells. Keratinocytes were metabolically labelled with 35S-methionine, and solubilized cell extracts were reacted with antibody to type VII collagen. The results indicate that the patient's keratinocytes synthesize type VII collagen and that the MI of the protein synthesized does not differ from that of an unaffected control. Because cultured cells from a patient severely affected with recessive dystrophic epidermolysis bullosa produce type VII collagen, the genetic defect, at least in this patient, is unlikely to reside in a major truncation of the type VII collagen molecule.

description: Sampling rate offsets (SROs) between devices in a heterogeneous wireless acoustic sensor network (WASN) can hinder the ability of distributed adaptive algorithms to perform as intended when they rely on coherent signal processing. In this paper, we present an SRO estimation and compensation method to allow the deployment of the distributed adaptive node-specific signal estimation (DANSE) algorithm in WASNs composed of asynchronous devices. The signals available at each node are first utilised in a coherence-drift-based method to blindly estimate SROs which are then compensated for via phase shifts in the frequency domain. A modification of the weighted overlap-add (WOLA) implementation of DANSE is introduced to account for SRO-induced full-sample drifts, permitting per-sample signal transmission via an approximation of the WOLA process as a time-domain convolution. The performance of the proposed algorithm is evaluated in the context of distributed noise reduction for the estimation of a target speech signal in an asynchronous WASN.

description: At present, analytical lab-on-chip devices find their usage in different facets of chemical analysis, biological analysis, point of care analysis, biosensors, etc. In addition, graphene has already established itself as an essential component of advanced lab-on-chip devices. Graphene-based lab-on-chip devices have achieved appreciable admiration because of their peerless performance in comparison to others. However, to accomplish a sustainable future a device must undergo Green-Screening to check its environmental compatibility. Thus, extensive research is carried out globally to make the graphene-based lab-on-chip green, though it is yet to be achieved. Nevertheless, as a ray of hope, there are few existing strategies that can be stitched together for feasible fabrication of environment-friendly green graphene-based analytical lab-on-chip, and those prospective pathways are reviewed in this paper.

description: Tourette Syndrome (TS) is a behavior disorder that onsets in childhood and is characterized by the expression of involuntary movements and sounds commonly referred to as tics. Behavioral therapy is the first-line treatment for patients with TS, and it helps patients raise awareness about tic occurrence as well as develop tic inhibition strategies. However, the limited availability of therapists and the difficulties for in-home follow up work limits its effectiveness. An automatic tic detection system that is easy to deploy could alleviate the difficulties of home-therapy by providing feedback to the patients while exercising tic awareness. In this work, we propose a novel architecture (T-Net) for automatic tic detection and classification from untrimmed videos. T-Net combines temporal detection and segmentation and operates on features that are interpretable to a clinician. We compare T-Net to several state-of-the-art systems working on deep features extracted from the raw videos and T-Net achieves comparable performance in terms of average precision while relying on interpretable features needed in clinical practice.

description: The problem of families, "Why are there three families of fermions?", is a long awaited question to be answered within a reasonable framework. We propose anti-SU($N$) groups for the unification of families in grand unification (GUT) groups, where the separation of color and weak gauge groups in the GUT is achieved by antisymmetric tensor Brout-Englert-Higgs boson instead of an adjoint representation. Theories of anti-SU($N$)'s are proposed for the unification of families. The minimal model is found as \antiSD \, GUT with the fermion representation [3]+2[2]+8[\bar-1]. We present an example in a Z(12-I) orbifold compactification, where the missing partner mechanism is also realized.
