title:  In Vitro Evaluation of the Reciprocating Disposable Prophylaxis Angle Versus the Rotating Disposable Prophylaxis Angle in Extrinsic Stain Removal Effectiveness
Creators: name: LaCross, Inma
Publisher: name: Old Dominion University Libraries
Year: 2006

description: The purpose of this study was to determine the extrinsic tooth stain removing effectiveness of a 90° counter-rotating disposable prophylaxis angle (DPA) with rubber cup as compared to the traditional 360° unirotational DPA with rubber cup. Four randomly assigned groups of cleaned, sterilized, extracted human teeth, artificially stained with coffee, tea, tobacco, and red wine were polished on the buccal and lingual surfaces using one of the two rubber cup DP As under study. Each dependent variable (four different stain types) was tested four times with each prophylaxis angle, using each of the four prophylaxis paste conditions, and three different rpm; therefore, 2 trials x 2 angles x 3 speeds x 4 stains x 4 grits = 192 trials on 96 teeth. For each trial, a rubber cup DPA attached to a handpiece and controlled by an eStylus™ was mounted on a researcher-designed testing apparatus that together controlled handpiece rpm and force of the rubber cup against the tooth; a timer was used to control contact time of the rubber cup against the tooth. Stain removal effectiveness of the DPA was measured, based on a before and after comparison of the tooth with a Bioform Color Ordered Shade Guide after the prophylaxis angle was used with one of three different grits of prophylaxis pastes and a trial using no paste at 1500, 2000, and 3000 rpm. The dental hygienist who scored the teeth was blind to the treatment status of each of the teeth. Four trials for each treatment were conducted and means and standard deviations were computed. Data were analyzed using a three-way analysis of variance at the .05 level.

After 192 trials on stained teeth, the results revealed no statistically significant difference between the two DPAs in extrinsic tooth stain removal. There was a statistically significant interaction among rpm (3,000) of the DPA and the grit abrasivity of the prophylaxis paste suggesting that additional study may be indicated since coarse prophylaxis pastes remove stain more rapidly, but in doing so, can scratch and roughen the tooth enamel. Extrinsic stain removal effectiveness of the two DP As were comparable when using different abrasivity prophylaxis paste and different rpm.

description: Aboriginal housing in Canada is in a state of crisis. The status quo is characterized by substandard and culturally inappropriate buildings, and insufficient access to essential services. This reality undermines individual and community health, wellbeing and socioeconomic development. Emerging green building methods and clean technologies have the potential to address key issues and problematic conditions in this context, where occupant health and safety, durability, and reduced operating and maintenance costs are primary concerns. Considerations for Aboriginal cultures are also essential to improved housing design, where their absence has perpetuated a legacy of cultural oppression. Adopting cultural considerations into Aboriginal housing design may increase sense of identity, belonging, ownership and responsibility. This research examines the integration of green building methods, clean technologies, and Aboriginal cultural design considerations as bases for improving Aboriginal housing. Recommendations are based on qualitative case studies within the Seabird Island, Saugeen, and Treaty 7 First Nations.

description: El siglo XX ha demostrado de manera reiterativa que los sueños de una parte de la población pueden convertirse en la pesadilla de los que no comparten tales ideales. La Albania socialista de Enver Hoxha (1908-1985) es, sin duda, una buena muestra de ello. Nacido tras la Segunda Guerra Mundial, el régimen enverista fue modifi cando su política exterior de alianzas con diversas potencias extranjeras (Yugoslavia, Unión Soviética y China). Tras cada ruptura con una u otra potencia internacional se llevaron a cabo las purgas pertinentes, que recibieron la oportuna denominación: titistas (proyugoslavos), jruschovistas (prosoviéticos) o prochinos. El régimen también persiguió con saña al arte y la literatura “desviacionistas” o “revisionistas”. En la década de 1970, en la que se desarrolla la novela de Rudi Erebara, el régimen también persiguió a literatos y artistas. Estamos ante las primeras consecuencias de la particular “revolución cultural” albanesa.

description: © 2020, © 2020 The Author(s). Published with license by Taylor & Francis Group, LLC. Epithelial-Mesenchymal Transition (EMT) and angiogenesis are crucial events for development of aggressive and often fatal Oral Squamous Cell Carcinomas (OSCCs). Both promote cancer progression and metastasis development, but while the former induces the loss of E-cadherin expression and, hence cadherin switching; the latter produces hematic blood vessel neo-formation and contribute to OSCC cell growth, tumor mass development, and dissemination. Cyclooxygenase-2 (COX-2) has an important role, not only in angiogenic mechanisms, but also in favoring cancer invasion. Indeed it decreases the expression of E-cadherin and leads to phenotypic changes in epithelial cells (EMT) enhancing their carcinogenic potential. Our aim is to evaluate the interplay between E-cadherin cytoplasmic delocalization, COX-2 up-regulation and COX-2 induced neo-angiogenesis in 120 cases of OSCC. We have analyzed the distribution and the number of neo-formed endothelial buds surrounding infiltrating cells that express COX-2, as well as the neo-formed vessels in chronic inflammatory infiltrate, which surround the tumor. A double immunostaining method was employed in order to verify co-localization of endothelial cell marker (CD34) and COX-2. IHC has also been used to assess E-cadherin expression. Our data demonstrate that the OSCC cells, which lose membranous E-cadherin staining, acquiring a cytoplasmic delocalization, overexpress COX-2. Moreover, we find a new CD34+ vessel formation (sprouting angiogenesis). Only basaloid type of OSCC showes low level of COX-2 expression together with very low level of neo-angiogenesis and consequent tumor necrosis. The well-known anti-metastatic effect of certain COX-2 inhibitors suggests that these molecules might have clinical utility in the management of advanced cancers.

This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Snacks, while widely consumed in the United States (U.S.), do not have a standard definition, complicating research to understand associations, if any, with weight status. Therefore, the purpose of this study was to examine the association between snacking frequency and weight status using various snacking definitions that exist in the scientific literature among U.S. adults (NHANES 2013–2016; ≥20y n = 9,711). Four event-based snacking definitions were operationalized including participant-defined snacks, eating events outside of meals, and operationally defined snacks based on absolute thresholds of energy consumed (>50 kcal). Weight status was examined using body mass index (BMI), waist circumference, and sagittal abdominal diameter risk. Logistic regression models examined snacking frequency and associations with weight status. Outcomes varied by the definition of a snack employed, but the majority of findings were null. Mean energy from snacks was significantly higher among women with obesity compared to women with normal weight when a snack was defined as any event outside of a typical mealtime (i.e. other than breakfast, lunch, dinner, super, brunch), regardless of whether or not it contributed ≥50 kcal. Further investigation into ingestive behaviors that may influence the relationship between snacking frequency and weight status is needed.
Spatial Curvature Falsifies Eternal Inflation

description: Inflation creates large-scale cosmological density perturbations that are characterized by an isotropic, homogeneous, and Gaussian random distribution about a locally flat background. Even in a flat universe, the spatial curvature measured within one Hubble volume receives contributions from long wavelength perturbations, and will not in general be zero. These same perturbations determine the Cosmic Microwave Background (CMB) temperature fluctuations, which are O(10^-5). Consequently, the low-l multipole moments in the CMB temperature map predict the value of the measured spatial curvature Ω_k. On this basis we argue that a measurement of |Ω_k| > 10^-4 would rule out slow-roll eternal inflation in our past with high confidence, while a measurement of Ω_k < -10^-4 (which is positive curvature, a locally closed universe) rules out false-vacuum eternal inflation as well, at the same confidence level. In other words, negative curvature (a locally open universe) is consistent with false-vacuum eternal inflation but not with slow-roll eternal inflation, and positive curvature falsifies both. Near-future experiments will dramatically extend the sensitivity of Ω_k measurements and constitute a sharp test of these predictions.

description: Due to the co-evolution of supermassive black holes and their host galaxies, understanding the mechanisms that trigger active galactic nuclei (AGN) are imperative to understanding galaxy evolution and the formation of massive galaxies. It is observationally difficult to determine the trigger of a given AGN due to the difference between the AGN lifetime and triggering timescales. Here, we utilize AGN population synthesis modeling to determine the importance of different AGN triggering mechanisms. An AGN population model is computed by combining an observationally motivated AGN triggering rate and a theoretical AGN light curve. The free parameters of the AGN light curve are constrained by minimizing a χsquared test with respect to the observed AGN hard X-ray luminosity function. The observed black hole space density, AGN number counts, and X-ray background spectrum are also considered as observational constraints. It is found that major mergers are not able to account for the entire AGN population. Therefore, non-merger processes, such as secular mechanisms, must also trigger AGN. Indeed, non-merger processes are the dominant AGN triggering mechanism at z \lesssim 1--1.5. Furthermore, the shape and evolution of the black hole mass function of AGN triggered by major mergers is intrinsically different from the shape and evolution of the black hole mass function of AGN triggered by secular processes.

description: The manifestation of failure in geomaterials and its proper analysis are constitutive aspects that geotechnical engineers are faced with routinely in design. In most instances, geostructures are examined at the ultimate plastic state where failure is deemed to occur along a slip surface where plastic deformations localize. This plasticity condition is classically analyzed with the Mohr-Coulomb failure criterion. However, other forms of failure also exist where the localization of deformations is totally absent such as in the case of static liquefaction. This distinct mode has been coined as ‘diffuse failure’ which has the peculiarity of occurring at stress levels well below the plastic limit, thus rendering a classic Mohr-Coulomb analysis insufficient. Hence, the signature of failure in geomaterials seems to be directly related to two principal modes by which it is manifested: one with localized slips, and another variant where deformations are diffused without any localization phenomena. In order to address the many subtle features of failure, a clear mathematical representation of the underlying physical phenomena is needed. In this thesis, failure is considered as an instability of homogeneous deformations, and as such the observed failuremode is a direct result of the underlying constitutive equations admitting bifurcations in solutions for the material response. Different failure criteria are derived, serving as failure indicators which signal the various modes that emerge during loading history following a certain hierarchy. To translate theory into engineering practice, the thesis endeavors to apply the above mathematical aspects of failure in the study of geomaterials undergoing multiphasic flow and thermal transport such as in the extraction of heavy oil from an oilsand reservoir in Alberta, Canada. Governing equations describing the physics of all phases (solid, water, gas and oil) involved are formulated within mixture theory using continuum mechanics principles. A special computational strategy is adopted to solve efficiently the coupled system of equations using both finite elements and finite differences. Finally, the developed computational model is tested in the context of an actual oil field case study implicating steam injection and oil production in an oilsand reservoir in Alberta, Canada. To close the loop, attention is obviously focused on material failure concepts developed in the first part of the thesis. Geomechanical properties that enter the computational model are obtained from a separate comprehensive laboratory testing of shales and oilsands at high temperature and pressure.

description: Privacy for online systems including social networks, specialized websites such as reviewing systems, movies forums, etc. have become primary concern people who use these websites. Users of these websites must register accounts and input personal information, which maybe directly related to their identities. Their reviews, tweeting, comments, or chat messages provide more information about them through their writing characteristics. This threatened to reveal their identities and other personal information. A patient's records need to be accessible for research purposes or be provided to a third party. The user’s identity or health status must remain protected. Current methods provide more tools to eliminate portions of text in the records that can be used to infer those sensitive information. We provide a new approach to select parts of the text that must be removed. The novelty of this approach is using information theoretic measures to capture the definition of sensitive inference. Using this approach we almost double the number of detected inferences compared to the existing state-of-the-art systems. Human characteristics such as writing characteristics can be used to identify them with more information. This information can be used to trace users' activities across websites by performing writing style matching. To protect users from being traced, obfuscating their writing styles is necessary. However this is not an easy-to-accomplish task. In this thesis, we will show that there are security flaws in current works and design a writing style obfuscation algorithm which has a number of important security properties. As stylometry techniques have been expanded to new domains such as tweets, comments, chat messages and codes, the same privacy concerns exist in both traditional and new domains. Number of challenges exist such as authors can be traced or identified across domains. We have analysed privacy of multi-user Twitter accounts, and showed that authors can be recognized using data from other domains such as blogs.

description: Maternal and under five-year-old mortality rates have reduced in the last two decades globally due to concerted effort, yet newborn deaths remain unacceptably prevalent. Behavior change is an important component of interventions to address newborn health problems in low-income countries. In Cambodia, maternal and newborn mortality has markedly decreased, and continued improvements will allow the country to achieve further reduction in newborn morbidity. The results of an implementation study of the Newborn Care and Infection Control Initiative using process evaluation are presented to provide insight into the trial implementation and context of the program that may have contributed to intervention results. The study utilized a mixed method process to explore the context, mechanisms, and implementation of intervention components: training of village health support group volunteers to provide home visits, training of midwives on infection prevention and control around the perinatal period, counseling on newborn care, and provision of training materials for counseling and intervention. Implementation was evaluated through quantitative and qualitative data collection including surveys, observation, semi-structured interviews, focus groups, and visual media. Descriptive statistics summarized the quantitative data and thematic analysis was used to explore the qualitative data. The evaluation identified several factors that might have influenced the outcomes of the trial: continuity of health center staff communication, timing and ability to complete home visits, and training quality. Additional support for parents in the perinatal period, preferably provided at the community level, will contribute to further improvement in health outcomes for newborns in this area. Researchers in this context should consider mechanisms to improve the coordination of health facility staff counseling while providing support and resources to ensure home visits to families with newborns are made on time. Attention to staffing, training, and quality of newborn health interventions is critical in planning for the scaling-up of newborn health programming.

description: The present study examined the positive developmental factors of First Nations youth. Online surveys were administered to 18 First Nations youths to measure their developmental assets (i.e., personal, social, family, school, and community strengths), school engagement (i.e., behavioural, emotional, and cognitive), and cultural identity. Results reveal that middle school students demonstrate higher degrees of all variables measured compared to high school students. Findings also indicate that this sample of First Nations youths possess a relatively low amount of developmental assets. Furthermore, it was found that the more developmental assets this sample of First Nations youth possess, the more they are engaged at school. Lastly, results indicated that school engagement was not related to the First Nations youths’ cultural identity. Interpretations of these findings along with implications, limitations, and suggestions for future research are provided.

description: © Copyright © 2020 Wilson, Thompson, McPherson, Zadikoff, Heckman and MacKinnon. Individuals with Parkinson's disease (PD) demonstrate deficits in muscle activation such as decreased amplitude and inappropriate bursting. There is evidence that some of these disturbances are more pronounced in extensor vs. flexor muscles. Surface EMG has been used widely to quantify muscle activation deficits in PD, but analysis of discharge of the underlying motor units may provide greater insight and be more sensitive to changes early in the disease. Of the few studies that have examined motor unit discharge in PD, the majority were conducted in the first dorsal interosseous, and no studies have measured motor units from extensor and flexor muscles within the same cohort. The objective of this study was to characterize the firing behavior of single motor units in the elbow flexor and extensor muscles during isometric contractions in people with mild-to-moderate PD. Ten individuals with PD (off-medication) and nine healthy controls were tested. Motor unit spike times were recorded via intramuscular EMG from the biceps and triceps brachii muscles during 30-s isometric contractions at 10% maximum voluntary elbow flexion and elbow extension torque, respectively. We selected variables of mean motor unit discharge rate, discharge variability, and torque variability to evaluate motor abnormalities in the PD group. The effects of group, muscle, and group-by-muscle on each variable were determined using separate linear mixed models. Discharge rate and torque variability were not different between groups, but discharge variability was significantly higher in the PD group for both muscles combined (p < 0.0001). We also evaluated the asymmetry in these motor variables between the triceps and biceps for each individual participant with PD to evaluate whether there was an association with disease severity. The difference in torque variability between elbow flexion and extension was significantly correlated with both the Hoehn and Yahr scale (rho = 0.71) and UPDRS (rho = 0.62). Our findings demonstrate that variability in motor output, rather than decreased discharge rates, may contribute to motor dysfunction in people with mild-to-moderate PD. Our findings provide insight into altered neural control of movement in PD and demonstrate the importance of measuring from multiple muscles within the same cohort.

description: Modelling the formation of super-km-sized planetesimals by gravitational collapse of regions overdense in small particles requires numerical algorithms capable of handling simultaneously hydrodynamics, particle dynamics and particle collisions. While the initial phases of radial contraction are dictated by drag forces and gravity, particle collisions become gradually more significant as filaments contract beyond Roche density. Here we present a new numerical algorithm for treating momentum and energy exchange in collisions between numerical superparticles representing a high number of physical particles. We adopt a Monte Carlo approach where superparticle pairs in a grid cell collide statistically on the physical collision time-scale. Collisions occur by enlarging particles until they touch and solving for the collision outcome, accounting for energy dissipation in inelastic collisions. We demonstrate that superparticle collisions can be consistently implemented at a modest computational cost. In protoplanetary disc turbulence driven by the streaming instability, we argue that the relative Keplerian shear velocity should be subtracted during the collision calculation. If it is not subtracted, density inhomogeneities are too rapidly diffused away, as bloated particles exaggerate collision speeds. Local particle densities reach several thousand times the mid-plane gas density. We find efficient formation of gravitationally bound clumps, with a range of masses corresponding to contracted radii from 100 to 400 km when applied to the asteroid belt and 150 to 730 km when applied to the Kuiper belt, extrapolated using a constant self-gravity parameter. The smaller planetesimals are not observed at low resolution, but the masses of the largest planetesimals are relatively independent of resolution and treatment of collisions.

description: Populations of nonlocally coupled, identical limit cycle oscillators can lead to the peculiar chimera state, in which subpopulations of synchronized and unsynchronized oscillators coexist in localized spatial domains. We study the existence and robustness of chimera states in populations of simple, complex and chaotic oscillators, which are different forms of oscillation realizable in experiments. In the case of simple oscillation, we investigate the existence and robustness of chimera states under physically relevant constraints in our model such as time delay and frequency heterogeneity. We show for the first time that chimera states can be extended to the general setting of complex and chaotic oscillators, in particular, we find spiral wave chimera together with synchronization defect lines. We also introduce several methods for selecting parameters in general models that lead to the formation of chimera states in 1D or 2D systems, which can provide important theoretical guidance to future experimental studies.
Forgiveness, Reconciliation and Hope in Trauma Healing
Creators: name: Worthington, Jr., Everett L .
Publisher: name: Revista d'Humanitats

description: In this talk, I argue that trauma healing is complex and individual. The internal experience of forgiveness can help heal traumas that have been experienced both individually and within a society because it (1) signals some perception of trustworthiness; (2) creates a desire to reconcile (though the person might not act on the desire), and (3) is perceived. Forgiveness can therefore lead to a change in one’s own and the other person’s behavior. Reconciliation is even harder than forgiveness. Forgiveness involves one person making a decision to forgive and experiencing emotional forgiveness. Reconciliation involves a society in which individuals on each confl icting side diff er both within and between the groups. Trustworthiness and perceptions by the other side that both sides are trustworthy are diffi cult to reach. But reconciliation is possible and it is aided by individuals forgiving others. Trustworthiness can be manifested by balancing justice and mercy, and trust can grow from perceptions of mutual trustworthiness. Trust can grow into hope, which can keep people seeking reconciliation even when it seems unlikely that it will occur.

description: © 2020, The Author(s). Roughly 10% of eukaryotic transmembrane proteins are found on the nuclear membrane, yet how such proteins target and translocate to the nucleus remains in dispute. Most models propose transport through the nuclear pore complexes, but a central outstanding question is whether transit occurs through their central or peripheral channels. Using live-cell high-speed super-resolution single-molecule microscopy we could distinguish protein translocation through the central and peripheral channels, finding that most inner nuclear membrane proteins use only the peripheral channels, but some apparently extend intrinsically disordered domains containing nuclear localization signals into the central channel for directed nuclear transport. These nucleoplasmic signals are critical for central channel transport as their mutation blocks use of the central channels; however, the mutated proteins can still complete their translocation using only the peripheral channels, albeit at a reduced rate. Such proteins can still translocate using only the peripheral channels when central channel is blocked, but blocking the peripheral channels blocks translocation through both channels. This suggests that peripheral channel transport is the default mechanism that was adapted in evolution to include aspects of receptor-mediated central channel transport for directed trafficking of certain membrane proteins.

description: We provide an individual analysis of 94 carbon enhanced metal-poor stars showing an s-process enrichment (CEMP-s) collected from the literature. The s-process enhancement observed in these stars is ascribed to mass transfer by stellar winds in a binary system from a more massive companion evolving faster toward the asymptotic giant branch (AGB) phase. The theoretical AGB nucleosynthesis models have been presented in Paper I. Several CEMP-s stars show an enhancement in both s and r-process elements (CEMP-s/r). In order to explain the peculiar abundances observed in CEMP-s/r stars, we assume that the molecular cloud from which CEMP-s formed was previously enriched in r-elements by Supernovae pollution. A general discussion and the method adopted in order to interpret the observations have been provided in Paper II. We present in this paper a detailed study of spectroscopic observations of individual stars. We consider all elements from carbon to bismuth, with particular attention to the three s-process peaks, ls (Y, Zr), hs (La, Nd, Sm) and Pb, and their ratios [hs/ls] and [Pb/hs]. The presence of an initial r-process contribution may be typically evaluated by the [La/Eu] ratio. We found possible agreements between theoretical predictions and spectroscopic data. In general, the observed [Na/Fe] (and [Mg/Fe]) provide information on the AGB initial mass, while [hs/ls] and [Pb/hs] are mainly indicators of the s-process efficiency. A range of 13C-pocket strengths is required to interpret the observations. However, major discrepancies between models and observations exist. We highlight star by star the agreements and the main problems encountered and, when possible, we suggest potential indications for further studies. These discrepancies provide starting points of debate for unsolved problems ...

El pacifismo de Soran Reader reconsiderado

description: En este artículo me dedico a reconsiderar el pacifismo moral de la filósofa Soran Reader (1963-2012). En la segunda sección reconstruyo los tres argumentos principales desarrollados por Reader en su artículo “Making Pacifism Plausible” (Haciendo el pacifismo plausible). En la tercera sección evalúo los argumentos de Reader y concluyo que el pacifismo moral de Reader es en efecto plausible. En la cuarta sección introduzco la noción del pacifismo político. El pacifismo moral es la tesis filosófica que mantiene que la guerra no se puede justificar moralmente. El pacifismo político, en cambio, es el movimiento político que busca abolir la institución de la guerra para reemplazarla por una institución de la paz. Mi propuesta es combinar el pacifismo político y el pacifismo moral con el fi n de argumentar que en el mundo contemporáneo nos encontramos en una situación de injusticia estructural en lo que se refiere a las resoluciones de conflictos internacionales. En el statu quo internacional la guerra es aceptada como institución para resolver conflictos internacionales, pero en el pacifismo moral la guerra es siempre moralmente problemática, argumento que, en la situación actual de injusticia estructural, cuando nos vemos amenazados por una invasión externa injusta, nos lleva a encontramos sin opciones para actuar de manera moralmente correcta. Tanto ir a la guerra como no ir nos presenta problemas morales graves. Sin alternativas viables, habrá ocasiones en las que terminemos yendo a la guerra para defender nuestro territorio y a nuestros hijos. Sin embargo, mantengo que debemos resistir la tentación de pensar que la guerra se nos presenta como una opción moral o justa, incluso en estas circunstancias. En la última sección, concluyo que la filosofía debe dejar de gastar tanta energía intelectual en proveer justificaciones filosóficas para la teoría de la guerra justa (que es ampliamente aceptada en los círculos filosóficos actuales) y debe dedicarse, en cambio, a demostrar que la guerra es injusta y que, precisamente por esta razón, debemos comprometernos a investigar cómo reemplazar la institución de la guerra por una institución de la paz, pensando cuál sería la forma apropiada para dicha institución. Por eso mismo me parece que hoy es realmente importante reconsiderar el pacifismo moral de Soran Reader.

description: © 2020, The Author(s). New developments in liquid scintillators, high-efficiency, fast photon detectors, and chromatic photon sorting have opened up the possibility for building a large-scale detector that can discriminate between Cherenkov and scintillation signals. Such a detector could reconstruct particle direction and species using Cherenkov light while also having the excellent energy resolution and low threshold of a scintillator detector. Situated deep underground, and utilizing new techniques in computing and reconstruction, this detector could achieve unprecedented levels of background rejection, enabling a rich physics program spanning topics in nuclear, high-energy, and astrophysics, and across a dynamic range from hundreds of keV to many GeV. The scientific program would include observations of low- and high-energy solar neutrinos, determination of neutrino mass ordering and measurement of the neutrino CP-violating phase δ, observations of diffuse supernova neutrinos and neutrinos from a supernova burst, sensitive searches for nucleon decay and, ultimately, a search for neutrinoless double beta decay, with sensitivity reaching the normal ordering regime of neutrino mass phase space. This paper describes Theia, a detector design that incorporates these new technologies in a practical and affordable way to accomplish the science goals described above.

description: Background: Telomeric DNA is highly susceptible to oxidative damage, and dietary habits may impact telomere attrition rates through the mediation of oxidative stress and chronic inflammation. Objectives: To examine the association between both the Dietary Inflammatory Index 2010 (DII) and the Alternative Healthy Eating Index 2010 (AHEI) with relative Leukocyte Telomere Length. Design: We conducted a cross-sectional analysis using baseline data from 301 healthy, inactive post-menopausal women. Diet quality was estimated using DII and AHEI scores derived from food frequency questionnaire data. LTL was measured using qPCR. Associations were examined using multivariable adjusted linear regression. Results: No statistically significant associations were detected between AHEI (p=0.20) or DII (p=0.91) and LTL in multivariable adjusted models. Conclusions: AHEI or DII scores were not related to LTL in this population. Future research is warranted to enhance understanding regarding the molecular processes involved in the relations between diet, telomere length and chronic disease risk.

Protein secondary structure prediction remains a vital topic with broad applications. Due to lack of a widely accepted standard in secondary structure predictor evaluation, a fair comparison of predictors is challenging. A detailed examination of factors that contribute to higher accuracy is also lacking. In this paper, we present: (1) new test sets, Test2018, Test2019, and Test2018-2019, consisting of proteins from structures released in 2018 and 2019 with less than 25% identity to any protein published before 2018; (2) a 4-layer convolutional neural network, SecNet, with an input window of ±14 amino acids which was trained on proteins ≤25% identical to proteins in Test2018 and the commonly used CB513 test set; (3) an additional test set that shares no homologous domains with the training set proteins, according to the Evolutionary Classification of Proteins (ECOD) database; (4) a detailed ablation study where we reverse one algorithmic choice at a time in SecNet and evaluate the effect on the prediction accuracy; (5) new 4- and 5-label prediction alphabets that may be more practical for tertiary structure prediction methods. The 3-label accuracy (helix, sheet, coil) of the leading predictors on both Test2018 and CB513 is 81–82%, while SecNet’s accuracy is 84% for both sets. Accuracy on the non-homologous ECOD set is only 0.6 points (83.9%) lower than the results on the Test2018-2019 set (84.5%). The ablation study of features, neural network architecture, and training hyper-parameters suggests the best accuracy results are achieved with good choices for each of them while the neural network architecture is not as critical as long as it is not too simple. Protocols for generating and using unbiased test, validation, and training sets are provided. Our data sets, including input features and assigned labels, and SecNet software including third-party dependencies and databases, are downloadable from dunbrack.fccc.edu/ss and github.com/sh-maxim/ss.

description: I am currently the Head Editor of a scientic journal in my institution. We are committed to improve the visibility of the published articles. A better and deeper understanding of the licensing of our articles is fundamental and belongs to our short term improvement plans. On the other hand, I am involved in the denition of the open access and open science policy in my institution. Therefore I thought that the CC Certicate for Educators can help with ideas and perspectives to contribute in the best manner to that project.
La desobediencia civil en democracia según Bertrand Russell y Martin Luther King
Creators: name: Prat Carvajal, Enric
Publisher: name: Revista d'Humanitats
Year: 2023

description: La desobediencia civil es una estrategia de lucha política que persigue cambiar el “status quo” inicialmente injusto, por una motivación colectiva y no interesada o personal, transgrediendo alguna norma jurídica y asumiendo a la vez sus consecuencias. No obstante, en un estado de derecho pareciera que la desobediencia civil no tenga lugar porque lo rigen leyes democráticas avaladas por mayorías parlamentarias. Sin embargo, según las aportaciones y experiencias de Russell y King, si la desobediencia se practica de manera no violenta y se limita a transgredir las leyes injustas y no todo un sistema que generaría caos y violencia. Por tanto, es legítimo seguir utilizando la desobediencia civil dentro de las democracias como una estrategia de mejora de sus imperfecciones. Que un sistema democrático permita la participación política y obedezca a la voluntad de las mayorías, no significa que todas las leyes sean perfectas y garanticen siempre todos los derechos. Las democracias deben ser controladas también por el activismo directo de la ciudadanía, y la desobediencia civil se convierte en un método de presión política abierto a la participación social, lo cual también es democratizador
