description: The membrane paradigm is the remarkable view that, to an external observer, a black hole appears to behave exactly like a dynamical fluid membrane, obeying such pre-relativistic equations as Ohm's law and the Navier-Stokes equation. It has traditionally been derived by manipulating the equations of motion. Here we provide an action formulation of this picture, clarifying what underlies the paradigm, and simplifying the derivations. Within this framework, we derive previous membrane results, and extend them to dyonic black hole solutions. We discuss how it is that an action can produce dissipative equations. Using a Euclidean path integral, we show that familiar semi-classical thermodynamic properties of black holes also emerge from the membrane action. Finally, in a Hamiltonian description, we establish the validity of a minimum entropy production principle for black holes.

description: To halt the proliferation of cancer cells by leveraging their surroundings, a closer look at a proposed bi-directional relationship between the tumor and its stroma is studied. While previous research has established key factors within this mechanism such as TGF-βand SDF-1, we still lack the knowledge about the mechanism by which reprogramming occurs. Using HCT-116 immortalized colorectal cancer(CRC)cell lines and the readily available human foreskin fibroblasts (HFF), the reprogramming of fibroblast to cancer-associated fibroblasts is analyzed using 3D culture while optimizing an in-vivo like CRC model to be used for drug toxicity and further inter-relational studies. To address this endeavor, a co-culture of the mentioned cells was assessed for markers to better understand how the addition of naïve fibroblast affect the growth of tumor-derived spheroids. In return, the morphology of the naïve fibroblasts in comparison to that of an adenocarcinoma in addition to the protein expression change of fibroblasts when in the vicinity of a tumor were studied. Markers and number of fibroblasts were observed to increase due to tumor interaction. The tumor model was successfully optimized and studied to understands the micro (spheroids) to macro (in vivo tumor) translation.

description: Coherently displaced harmonic oscillator number states of a harmonically bound ion can be coupled to two internal states of the ion by a laser-induced motional sideband interaction. The internal states can subsequently be read out in a projective measurement via state-dependent fluorescence, with near-unit fidelity. This leads to a rich set of line shapes when recording the internal-state excitation probability after a sideband excitation, as a function of the frequency detuning of the displacement drive with respect to the ion's motional frequency. We precisely characterize the coherent displacement based on the resulting line shapes, which exhibit sharp features that are useful for oscillator frequency determination from the single quantum regime up to very large coherent states with average occupation numbers of several hundred. We also introduce a technique based on multiple coherent displacements and free precession for characterizing noise on the trapping potential in the frequency range of 500 Hz to 400 kHz. Signals from the ion are directly used to find and eliminate sources of technical noise in this typically unaccessed part of the spectrum.

description: Mobile phones play a very important role in our life. Mobile phone sales have been soaring over the last decade due to the growing acceptance of technological innovations, especially by Generations Y and Z. Understanding the change in customers' requirement is the key to success in the smartphone business. New, strong mobile phone models will emerge if the voice of the customer can be heard. Although it has been widely known that country of origin has serious impact on the attitudes and purchase decisions of mobile phone consumers, there lack substantial studies that investigate the mobile phone preference of young adults aged 18-25, members of late Generation Y and early Generation Z. In order to investigate the role of country of origin in mobile phone choice of Generations Y and Z, an online survey with 228 respondents was conducted in Hungary in 2016. Besides the descriptive statistical methods, crosstabs, ANOVA and Pearson correlation are used to analyze the collected data and find out significant relationships. Factor analysis (Principal Component Analysis) is used for data reduction to create new factor components. The findings of this exploratory study support the idea that country of origin plays a significant role in many respects related to young adults' mobile phone choice. Mobile phone owners with different countries of origin attribute crucial importance to the various product features including technical parameters, price, design, brand name, operating system, and memory size. Country of origin has a moderating effect on the price sensitivity of consumers with varied net income levels. It is also found that frequent buyers of mobile phones, especially US brand products, spend the most significant amount of money for their consumption in this aspect.

 The casted burrows of M. depressus were complex, with multiple entrances and branches (Figures 2 and 3). In fact, we never managed to make a complete cast of an entire burrow as the tunnels always continued after where the plaster stopped. One burrow appeared to have five entrances and another had two entrances (the 10 burrow entrances into which plaster was poured ultimately proved to belong to five burrows). Branches were observed leading in every direction and tunnels had various slopes and angles. The maximum depth of a cast was 35 cm, at which the water level was reached. In two casted burrows a single crab was found. In the three other burrows the crabs were probably able to escape, as the burrows were more extensive than our casts. The 16 excavated burrows were similarly complex as the casted burrows. In six of the 16 excavated burrows more than one crab per burrow was encountered (up to four crabs per burrow; Figure 4). In total 27 crabs were captured, of which we identified seven as males and eight as females. Sex could not be convincingly determined in 12 smaller individuals. There was no relationship between burrow size at entrance and crab size (t = 1.109, P = 0.28, R2 = 0.01; Figure 4).

description: The ability to respond to stress is universal in all domains of life. Failure to properly execute the stress response compromises the fitness of the organism. Several key stress pathways are conserved from unicellular organisms to higher eukaryotes, so knowledge of how these pathways operate in model organisms is crucial for understanding stress-related diseases and aging in humans. The mechanisms of stress tolerance have been well-studied in the budding yeast Saccharomyces cerevisiae. Yeast respond to diverse stresses by initiating both general and stress-specific responses that generally protect the cells during and after the stress exposure. While previous work has revealed mechanistic insights on adaptation and survival under mild and long-term exposure to stress, how they cope with acute exposure to lethal stress is not well understood. Here, we combined transcriptional profiling, fitness profiling, and laboratory evolution to investigate how S. cerevisiae survive acute exposure to lethal ethanol stress. By using high throughput methods such as RNA-seq and barcode sequencing of the pooled yeast deletion library, we were able to discover and characterize both existing and novel pathways that yeast utilize to adapt to and survive ethanol stress. We found both ethanol-specific and as well general stress response mechanisms. We were also able to evolve a strain of ethanol under lethal ethanol stress to exhibit a survival of at least an order of magnitude greater than the parental wild-type strain. Additionally, this evolved strain exhibited cross protection to other stresses without compromising bulk growth rate. We found that this strain adapted its global expression levels to a post-stress state, making it more robust to various stresses even under optimal growth conditions.

description: We show that a multi-walled carbon nanotube film can be used as the sensing element of a low-cost sensor for the alcoholic concentration in liquid solutions. To this purpose, we investigate the electrical resistance of the film as a function of the isopropanol concentration in a water solution. The analysis reveals a growing resistance with increasing isopropanol concentration and a fast response. The sensing element is re-usable as the initial resistance value is restored once the solution has evaporated. The electrical resistance increases linearly when the multi-walled carbon nanotube film is exposed to common beverages with increasing alcoholic content. This work paves the way for the development of low-cost, miniaturized MWCNT-based sensors for quality monitoring and control of alcoholic beverages and general liquid solutions.

description: The aim of this study was to investigate the effect of yoga on anxiety using meta-analytic methods, examining overall effect size, the effect size of sub-categories of dependent variables, and moderation.
      A systematic search was conducted for published randomized controlled trials on yoga and anxiety on electronic databases over key terms. Reference lists of quantitative studies and literature review articles were inspected for additional articles. Once included studies were determined, outcome data were extracted and moderators were coded across studies in order to characterize differences in study sample, delivery method, and type of dependent variable. Effect size aggregation and omnibus analyses were performed, and moderator tests were conducted.
      Results support the hypothesis that yoga significantly decreases anxiety symptoms, in addition to symptoms more globally (i.e., anxiety and other mental health outcomes, physical health outcomes, etc taken in aggregate).   Results from sub-omnibus analysis show significant effects of the yoga intervention on biological measures, non-anxiety mental health outcomes, physical health measures, stress, mental and physical health outcomes combined, and life satisfaction. In addition, significant moderation was found by location, with highest effects appearing in Indian samples.

Characterization of the Transformation/Transition of Naïve Fibroblasts to Cancer Associated Fibroblasts using 3D Co-cultures

description: The tumor stoma is an important component of the tumor that plays an increasingly significant role as the tumor grows and progresses, and encompasses abasement membrane, resident fibroblasts, extracellular matrix, immune cells, and endothelial cells lining the vasculature. Fibroblasts are a common and major stromal cell type. Although typical naive fibroblasts display suppressive functions against cancer-initiating and metastatic cells through a variety of mechanisms (cell-cell interaction, paracrine signaling by soluble factors, ECM integrity, etc.).This anti-inflammatory role is lost when fibroblasts evolve into cancer-associated fibroblasts (CAFs), which have been the subject of many recent studies as well as potential new cancer targets. The main aim of the study is to evaluate the reprogramming of the naïve fibroblast when cultured in proximity to tumor cells using the 3D spheroid model and to further analyze the effect of activatedfibroblast on tumor cellswithin spheroids by assessing their rates of proliferation.To accomplish our goal, various approaches were employed, including Flow cytometryand immunofluorescence staining using histological tissues.By performing a flow cytometry on 2D condition, we saw 2 Pankeratin+ populations which clearly means that fibroblasts are exerting effects on the tumor cell population. This implied that fibroblasts are attenuating the tumor cells.
Yiddish and the Avant-Garde in American Jewish Poetry

Subjects: Comparative literature

description: This dissertation traces the evolution of a formalist literary strategy through the twentieth century in both Yiddish and English, through literary and historical analyses of poets and poetic groups from the turn of the century until the 1980s.  It begins by exploring the ways in which the Yiddish poet Yehoash built on the contemporary interest in the primitive as he developed his aesthetics in the 1900s, then turns to the modernist poetic group In zikh (the Introspectivists) and their efforts to explore primitive states of consciousness in individual subjectivity.  In the third chapter, the project turns to Louis Zukofsky's inclusion of Yehoash's Yiddish translations of Japanese poetry in his own English epic, written in dialogue with Ezra Pound.  It concludes with an examination of the Language poets of the 1970s, particularly Charles Bernstein's experimental verse, which explores the way that language shapes consciousness through the use of critical and linguistic discourse.  Each of these poets or poetic groups uses experimental poetry as a lens through which to peer at the intersections of language and consciousness, and each explicitly identifies Yiddish (whether as symbol or reality) as an essential component of their poetic technique.

description: It is shown how the technique of restricted path integrals (RPI) or quantum corridors (QC) may be applied for the analysis of relativistic measurements. Then this technique is used to clarify the physical nature of thermal effects as seen by an accelerated observer in Minkowski space-time (Unruh effect) and by a far observer in the field of a black hole (Hawking effect). The physical nature of the "thermal atmosphere" around the observer is analysed in three cases: a) the Unruh effect, b) an eternal (Kruskal) black hole and c) a black hole forming in the process of collapse. It is shown that thermal particles are real only in the case (c). In the case (b) they cannot be distinguished from real particles but they do not carry away mass of the black hole until some of these particles are absorbed by the far observer. In the case (a) thermal particles are virtual.

description: Dynamic classifier selection systems aim to select a group of classifiers that is most adequate for a specific query pattern. This is done by defining a region around the query pattern and analyzing the competence of the classifiers in this region. However, the regions are often surrounded by noise which can difficult the classifier selection. This fact makes the performance of most dynamic selection systems no better than static selections. In this paper, we demonstrate that the performance dynamic selection systems end up limited by the quality of the regions extracted. Thereafter, we propose a new dynamic classifier selection that improves the regions of competence in order to achieve higher recognition rates. obtained from several classification databases show the proposed method not only increase the recognition performance but also decreases the computational cost.

description: Substituted naphthalene anions (deprotonated 2-naphthol and 6-hydroxy-2-naphthoic acid) are spectroscopically probed in a tandem drift tube ion mobility spectrometer (IMS). Target anions are selected according to their drift speed through nitrogen buffer gas in the first IMS stage before being exposed to a pulse of tunable light that induces either photodissociation or electron photodetachment, which is conveniently monitored by scavenging the detached electrons with trace \ce{SF6} in the buffer gas. The photodetachment action spectrum of the 2-naphtholate anion exhibits a band system spanning 380-460\,nm~with a prominent series of peaks spaced by 440\,\cme, commencing at 458.5\,nm, and a set of weaker peaks near the electron detachment threshold corresponding to transitions to dipole-bound states. The two deprotomers of 6-hydroxy-2-naphthoic acid are separated and spectroscopically probed independently. The molecular anion formed from deprotonation of the hydroxy group possesses a photodetachment action spectrum similar to that of the 2-naphtholate anion with an onset at 470\,nm and a maximum at 420\,nm. Near threshold, photoreaction with \ce{SF6} is observed with displacement of an OH group by an F atom. In contrast, the anion formed from deprotonation of the carboxylic acid group features a photodissociation action spectrum, recorded on the \ce{CO2} loss channel, lying to much shorter wavelength with an onset at 360\,nm and maximum photoresponse at 325\,nm.

It is shown that such maps have continuously many conditionally invariant measures $μ_σ$ scaling at the fixed point at x=0 as $x^σ$, but smooth elsewhere. Here $σ$ should be smaller than a critical value $σ_{c}$ that is related to the spectral properties of the Frobenius-Perron operator. The corresponding natural measures are proven to be entirely concentrated on the fixed point.

description: On April 11th 2019 the Sudanese people succeeded in ending the 30-year presidency of Omar Al Bashir. This paper discusses the transformational impact of months of protest on conceptions of Sudanese national identity within the revolutionary community. It is argued that a human rights state was created in the Sudan, comprised of revolutionaries practicing and embodying human rights, which transcended deeply entrenched ethnic, gendered, regional and religious divides and engendered a more inclusive national identity in its wake. Focusing on the revolutionary experiences in Khartoum, Nyala (Darfur), Kadugli (Nuba Mountains) and Atbara, this paper explores the oft-neglected and mischaracterized relationship between human rights, revolutions and nationalism. By focusing on protester testimony and the artistic artefacts of the revolution, the westerncentricity and elitism of conventional human rights approaches is challenged as the experiences of non-elite and non-western actors in Sudan are foregrounded and the localization of human rights through revolutionary protest in these spaces elucidated.

Yoga as a treatment for reducing maternal stress and negative birth outcomes

Publisher: name: Columbia University
Year: 2012
Subjects: Obstetrics

description: In America today, over 15 million people practice yoga. In recent years the practice has been specialized and adapted for the pregnant body. From this, a body of research developed. Past research has focused on basic concepts of yoga, and found significant benefits for the mother. However, fewer studies have done follow-ups to look at birth outcomes and long-term treatment effects of practicing yoga. This study will investigate how to reduce maternal stress and pain, as well as negative birth outcomes in a high-risk population of mothers, by answering the question what kinds of yoga and at what point during pregnancy yoga is useful? This study will specifically target pregnant women whose fetus has been diagnosed with a congenital heart defect. The diagnosis is given around 14 weeks, and with it mothers experience an extraordinary amount of stress. Stress has been shown to increase the risk of premature delivery and low birth weight, which can have long-term effects on the neonate (Narendran, Nagarathna, Narendran, Gunasheela and Nagendra, 2005). Participants will take the Perceived Stress Scale and Brief Pain Inventory when entering the study. They will be randomly assigned to one of five conditions: Vinyasa yoga starting at time of diagnosis, Vinyasa yoga starting at the beginning of third trimester, hatha yoga starting at time of diagnosis, hatha yoga starting at the beginning of third trimester or receiving literature on stress reduction without yoga. Participants will be instructed to use one of two local yoga studios three times a week. Every 3-4 weeks, mothers will go to their OB-GYN for routine blood pressure check, blood drawl, saliva test for cortisol and ultrasound. At time of delivery, results of birth outcomes and a final evaluation on maternal stress will be taken. The results will indicate whether one type of yoga has benefits that the other does not, such as one might reduce pain or stress more than another. Another predicted result is that their will be a significant benefit to practicing any kind of yoga compared to standard obstetric procedures, and yoga practiced throughout pregnancy will decrease negative birth outcomes and maternal stress more than practicing yoga only in the third trimester. This will suggest that yoga is a comprehensive, holistic and long-term approach for reducing stress, pain and negative birth outcomes in high-risk pregnancies. If the hypothesis holds true, yoga during pregnancy might become a widely used treatment, which will be advantageous, not just high-risk mother, but all pregnant women. Ultimately, the implications of this research will provide a useful tool for revising standard obstetric recommendations, which are currently limited.

description: We perform numerical simulations of the gravitational collapse of a spherically symmetric scalar field. For those data that just barely do not form black holes we find the maximum curvature at the position of the central observer. We find a scaling relation between this maximum curvature and distance from the critical solution. The scaling relation is analogous to that found by Choptuik for black hole mass for those data that do collapse to form black holes. We also find a periodic wiggle in the scaling exponent.

description: Based on $ab$ $initio$ calculations and low-energy effective $k{\cdot}p$ model, we propose a type of Weyl nodal point-line fermion, composed of 0D Weyl points and 1D Weyl nodal line, in ferromagnetic material Eu$_5$Bi$_3$. In the absence of spin-orbital coupling (SOC), the spin-up bands host a pair of triply degenerate points together with a unique bird-cage like node structure. In the presence of SOC with (001) magnetization, each triplet point splits into a double Weyl point and a single Weyl point accompanied by two nodal rings, forming two sets of Weyl nodal point-line fermions near the Fermi level. The novel properties of Weyl nodal point-line fermion are explored by revealing the unusual Berry curvature field and demonstrating the pinned chiral surface states with exotic Fermi arcs at different planes. Moreover, a large anomalous Hall conductivity of -260 ($\hbar$/$e$)($Ω$cm)$^{-1}$ parallel to [001] direction is predicted. Our work offers a new perspective for exploring novel topological semimetal states with diverse band-crossing dimensions, and provides an ideal material candidate for future experimental realiztion.

description: We present new results from the Parallaxes of Southern Extremely Cool dwarfs program to measure parallaxes, proper motions and multi-epoch photometry of L and early T dwarfs. The observations were made on 108 nights over the course of 8 years using the Wide Field Imager on the ESO 2.2m telescope. We present 118 new parallaxes of L \& T dwarfs of which 52 have no published values and 24 of the 66 published values are preliminary estimates from this program. The parallax precision varies from 1.0 to 15.5 mas with a median of 3.8 mas. We find evidence for 2 objects with long term photometric variation and 24 new moving group candidates. We cross-match our sample to published photometric catalogues and find standard magnitudes in up to 16 pass-bands from which we build spectral energy distributions and H-R diagrams. This allows us to confirm the theoretically anticipated minimum in radius between stars and brown dwarfs across the hydrogen burning minimum mass. We find the minimum occurs between L2 and L6 and verify the predicted steep dependence of radius in the hydrogen burning regime and the gentle rise into the degenerate brown dwarf regime. We find a relatively young age of 2 Gyr from the kinematics of our sample.

description: A spherical gravitational wave antenna is distinct from other types of gravitational wave antennas in that only a single detector is necessary to determine the direction and polarization of a gravitational wave. Zhou and Michelson showed that the inverse problem can be solved using the maximum likelihood method if the detector outputs are independent and have normally distributed noise with the same variance. This paper presents an analytic solution using only linear algebra that is found to produce identical results as the maximum likelihood method but with less computational burden. Applications of this solution to gravitational waves in alternative symmetric metric theories of gravity and impulsive excitations also are discussed.

description: The hierarchical structure of production planning has the advantage of assigning different decision variables to their respective time horizons and therefore ensures their manageability. However, the restrictive structure of this top-down approach implying that upper level decisions are the constraints for lower level decisions also has its shortcomings. One problem that occurs is that deterministic mixed integer decision problems are often used for long-term planning, but the real production system faces a set of stochastic influences. Therefore, a planned utilisation factor has to be included into this deterministic aggregate planning problem. In practice, this decision is often based on past data and not consciously taken. In this paper, the effect of long-term forecast error on the optimal planned utilisation factor is evaluated for a production system facing stochastic demand and the benefit of exploiting this decision's potential is discussed. Overall costs including capacity, backorder and inventory costs, are determined with simulation for different multi-stage and multi-item production system structures. The results show that the planned utilisation factor used in the aggregate planning problem has a high influence on optimal costs. Additionally, the negative effect of forecast errors is evaluated and discussed in detail for different production system environments.

description: The conventional postulate for the probabilistic interpretation of quantum mechanics is asymmetric in preparation and measurement, making retrodiction reliant on inference by use of Bayes' theorem. Here, a more fundamental symmetric postulate is presented, from which both predictive and retrodictive probabilities emerge immediately, even where measurement devices more general than those usually considered are involved. It is shown that the new postulate is perfectly consistent with the conventional postulate.

description: The rate of adolescent unintended pregnancy in the United States is high compared to other developed countries. While past research and interventions have largely focused on young women, the role of young men in pregnancy prevention has increasingly been recognized. Studies have assessed young men’s knowledge and attitudes toward pregnancy prevention as well as their role in male-controlled methods of birth control like condoms or withdrawal. However, less is known about how young men can contribute to or participate in decision-making with female partners about contraception other than condoms. The purpose of this systematic review was to explore how young men communicate with their partners and its impact on contraception use to prevent pregnancy. A systematic review of five databases was conducted to identify English-language articles published from January 1, 2002, through July 7, 2018. The review specifically explored how male partner communication affects female partner use of contraception other than condoms among young men ages 11-24 years. The systematic review explored additional questions, including those pertaining to the timing of partner communication in a relationship, strategies employed by young men, and which dynamics of partner communication are measured in studies. Of the 15 articles identified as exploring areas of communication, five of the articles used quantitative analysis to measure any association between partner communication and contraception use, and three of those produced statistically significant findings suggesting that communication increases the use of contraception other than condoms. Three qualitative studies provided supporting narratives of how young men have communicated with partners and influenced their contraception use with female partners. The remaining seven articles explored the other research questions of timing, strategies, and dynamics identifying topics, prompts, and communication cues among young men. Measurements of both communication and contraception varied across studies. With the small number of studies identified in this systematic review, it is recommended that future research seek to corroborate the relationship between partner communication and contraception use with more robust and precise measurements of both communication and contraception.

description: Learning via apprenticeship is widely regarded as a powerful mechanism. To examine the role of apprenticeship learning and practice in developing argumentive thinking and writing, young adolescents (n = 64) participated in a four-week dialogic argumentation activity. They drew on available evidence and engaged 20 daily sessions in one-to-one electronic dialogues on contemporary social issues, anonymously, with a series of opposing-side partners. To assess the proposition that adolescents' argumentation skill advances via apprenticeship with a more skilled partner, in an experimental (but not control) discourse condition, a skilled adult arguer replaced a peer in half of the dialogues. Effects on students were evaluated in the dialogue and individual writing contexts. In the dialogue context, performance in initial peer dialogues during the first day of the workshop and in a final dialogic assessment on a new topic were evaluated. In the individual writing context, performance on the last workshop-debate-topic essay and non-workshop-debate topic essay were evaluated. Data were analyzed according to previously identified and well-validated coding schemes on counterargument and argument strategies. Although all participants showed skill gains, students in the experimental condition advanced in argumentive reasoning more rapidly than those in the peer-only control condition. Specifically, the strongest counterargument strategy (counter-undermine) appeared in greater proportions of idea units in the dialogues of students in the experimental condition, compared to those in the comparison condition. Only “weaken-other” improvements in dialogue reached significance in transferring to essays. These findings extend upon and support previous work on the power of dialogic engagement and engagement with more competent others as a mechanism of apprenticeship learning. Pedagogical and social implications are discussed.

description: Predator–prey interactions have been suggested as drivers of diversity in different lineages, and the presence of anti-predator defences in some clades is linked to higher rates of diversification. Warning signals are some of the most widespread defences in the animal world, and there is evidence of higher diversification rates in aposematic lineages. The mechanisms behind such species richness, however, are still unclear. Here, we test whether lineages that use aposematism as anti-predator defense exhibit higher levels of genetic differentiation between populations, leading to increased opportunities for divergence. We collated from the literature more than 3000 pairwise genetic differentiation values across more than 700 populations from over 60 amphibian species. We find evidence that over short geographical distances, populations of species of aposematic lineages exhibit greater genetic divergence relative to species that are not aposematic. Our results support a scenario where the use of warning signals could restrict gene flow, and suggest that anti-predator defences could impact divergence between populations and potentially have effects at a macro-evolutionary scale.
