description: Background and Objectives: Studies have highlighted psychosocial factors associated with drug use among adolescents. Association of specific psychiatric comorbidity with substance use has not been properly established in Brazil. This study aimed to investigate alcohol, tobacco, and marijuana use by 15–18-year-old high school Brazilian students and to estimate associations with psychiatric symptoms. Methods: A cross-sectional survey of 4,034 students from 128 public and private schools in São Paulo State was carried out using a two-step probability sample. Data were collected through self-report standardized questionnaires including questions on substance use patterns and the Strengths and Difficulties Questionnaire (SDQ). Key outcome variables were past-month use and past-month frequent use of alcohol, tobacco and marijuana. Questionnaires with missing information were excluded, resulting in a final sample of 2,532 adolescents. Weighted data was analyzed through logistic regressions, adjusted by gender and by socio-economic status (SES). Results: Regarding SDQ total score, 43.6% of students had no psychiatric symptoms, 7.9% had subclinical symptoms and 48.5% presented clinically significant symptoms. Respondents with a clinically significant SDQ score were more likely to be past month alcohol (aOR = 1.51; 95%CI 1.22–1.88), tobacco (aOR = 1.82; 95%CI 1.25–2.66), and marijuana (aOR = 1.79; 95%CI 1.21–2.64) users as compared to those with no symptomatology. Discussion and Conclusions: Psychopathological symptoms were associated with alcohol, tobacco and marijuana use by 15–18-year-old adolescents. These associations should also be considered when planning public policies of mental health promotion. Scientific Significance: This study discusses the importance of the association between psychopathological symptoms and substance use in a middle-income country, with high level of social inequalities, in a state representative sample.

description: The mass distribution of dark matter halos is a sensitive probe of primordial non-Gaussianity (NG). We derive an analytical formula of the halo mass function by perturbatively computing excursion set path-integrals for a non-Gaussian density field with non-vanishing skewness, fnl. We assume a stochastic barrier model which captures the main features of the ellipsoidal collapse of halos. Contrary to previous results based on extensions of the Press-Schechter formalism to NG initial conditions, we find that the non-spherical collapse of halos directly alter the signature of primordial NG. This points toward a potential degeneracy between the effect of primordial non-Gaussianity and that of non-linear halo collapse. The inferred mass function is found to be in remarkable agreement with N-body simulations of NG local type. Deviations are well within numerical uncertainties for all values of -80 < fNL^loc < 300 in the range of validity of the perturbative calculation. Moreover, the comparison with simulation results suggests that for fNL > 150 or fNL < -50 the non-linear collapse of halos, as described by our barrier model, strongly deviates from that of Gaussian initial conditions. This is not surprising since the effect of non-linear gravitational processes may be altered by initially large NG. Hence, in the lack of prior theoretical knowledge, halo collapse model parameters should be included in statistical halo mass function data analysis which aim to constrain the signature of primordial NG

Towards a high-performance scalable storage system for workflow applications
Creators: name: Vairavanathan, Emalayan
Publisher: name: University of British Columbia
Year: 2012

description: This thesis is motivated by the fact that there is an urgent need to run scientific many-task workflow applications efficiently and easily on large-scale machines. These applications run at large scale on supercomputers and perform large amount of storage I/O. The storage system is identified as the main bottleneck on large-scale computers for many-task workflow applications. The goal of this thesis is to identify the opportunities and recommend solutions to improve the performance of many-task workflow applications. To achieve the above goal this thesis proposes a two-step solution. As the first step, this thesis recommends and designs an intermediate storage system which aggregates the resources available on compute nodes (local disk, SSDs, memory and network) and provides a minimal POSIX API required by workflow applications. An intermediate storage system facilitates a high performance scratch space for workflow applications and allows the applications to scale transparently compare to a regular shared storage systems. As the second step, this thesis performs a limit study on workflow-aware storage system: an intermediate storage that is tuned depending on I/O characteristics of a workflow application. Evaluation with synthetic and real workflow applications highlights the significant performance gain attainable by an intermediate storage system and a workflow-aware storage system. The evaluation shows that an intermediate storage can bring up to 2x performance gain compared to a central storage system. Further a workflow-aware storage system can bring up to 3x performance gain compared to a vanilla distributed storage system that is unaware of the possible file-level optimizations. The findings of this research prove that an intermediate storage system with minimal POSIX API is a promising direction to provide a high-performance scalable storage system for workflow applications. The findings also strongly advocate and provide design recommendations for a workflow-aware storage system to achieve better performance gain.

description: Recent progress on scattering amplitudes has benefited from the mathematical technology of symbols for efficiently handling the types of polylogarithm functions which frequently appear in multi-loop computations. The symbol for all two-loop MHV amplitudes in planar SYM theory is known, but explicit analytic formulas for the amplitudes are hard to come by except in special limits where things simplify, such as multi-Regge kinematics. By applying symbology we obtain a formula for the leading behavior of the imaginary part (the Mandelstam cut contribution) of this amplitude in multi-Regge kinematics for any number of gluons. Our result predicts a simple recursive structure which agrees with a direct BFKL computation carried out in a parallel publication.

description: We investigate on the scalability of multihop wireless communications, a major concern in networking, for the case that users access content replicated across the nodes. In contrast to the standard paradigm of randomly selected communicating pairs, content replication is efficient for certain regimes of file popularity, cache and network size. Our study begins with the detailed joint content replication and delivery problem on a 2D square grid, a hard combinatorial optimization. This is reduced to a simpler problem based on replication density, whose performance is of the same order as the original. Assuming a Zipf popularity law, and letting the size of content and network both go to infinity, we identify the scaling laws and regimes of the required link capacity, ranging from O(\sqrt{N}) down to O(1).

Modular localization and the holistic structure of causal quantum theory, a historical perspective

description: Recent insights into the conceptual structure of localization in QFT ("modular localization") led to clarifications of old unsolved problems. The oldest one is the Einstein-Jordan conundrum which led Jordan in 1925 to the discovery of quantum field theory. This comparison of fluctuations in subsystems of heat bath systems (Einstein) with those resulting from the restriction of the QFT vacuum state to an open subvolume (Jordan) leads to a perfect analogy; the globally pure vacuum state becomes upon local restriction a strongly impure KMS state. This phenomenon of localization-caused thermal behavior as well as the vacuum-polarization clouds at the causal boundary of the localization region places localization in QFT into a sharp contrast with quantum mechanics and justifies the attribute "holstic". In fact it positions the E-J Gedankenexperiment into the same conceptual category as the cosmological constant problem and the Unruh Gedankenexperiment. The holistic structure of QFT resulting from "modular localization" also leads to a revision of the conceptual origin of the crucial crossing property which entered particle theory at the time of the bootstrap S-matrix approach but suffered from incorrect use in the S-matrix settings of the dual model and string theory. The new holistic point of view, which strengthens the autonomous aspect of QFT, also comes with new messages for gauge theory by exposing the clash between Hilbert space structure and localization and presenting alternative solutions based on the use of stringlocal fields in Hilbert space. Among other things this leads to a radical reformulation of the Englert-Higgs symmetry breaking mechanism.

description: Aim: Concurrently with increasingly permissive attitudes towards marijuana use and its legalization, the prevalence of marijuana use has increased in recent years in the U.S. Substance use is generally more prevalent in men than women, although for alcohol, the gender gap is narrowing. However, information is lacking on whether time trends in marijuana use differ by gender, or whether socioeconomic status in the context of the Great Recession may affect these changes. Methods: Using repeated cross-sectional data from the National Survey on Drug Use and Health (2002–2014), we examined changes over time in prevalence of past-year marijuana use by gender, and whether gender differences varied across income levels. After empirically determining a change point in use in 2007, we used logistic regression to test interaction terms including time, gender, and income level. Results: Prevalence of marijuana use increased for both men (+4.0%) and women (+2.7%) from 2002 to 2014, with all of the increase occurring from 2007 to 2014. Increases were greater for men, leading to a widening of the gender gap over time (p < 0.001). This divergence occurred primarily due to increased prevalence among men in the lowest income level (+6.2%) from 2007 to 2014. Conclusion: Our findings are consistent with other studies documenting increased substance use during times of economic insecurity, especially among men. Corresponding with the Great Recession and lower employment rate beginning in 2007, low-income men showed the greatest increases in marijuana use during this period, leading to a widening of the gender gap in prevalence of marijuana use over time.

description: The superposition of chiral states of chiral molecules, as delocalized quantum states of a many-particle system, can be used for the experimental investigations of decoherence theory. In this regard, a great challenge is the precise quantification of the robustness of these superpositions against environmental effects. The methods so far proposed need the detailed specification of the internal states of the molecule, usually requiring heavy numerical calculations. Here, by using the linearized quantum Boltzmann equation and by borrowing ideas employed for analyzing other quantum systems, we present a general and simple approach, of large applicability, which can be used to compute the dominant contribution to the decoherence rate for the superpositions of chiral states of chiral molecules, due to environmental scattering.

description: Aims: Several states in the U.S. have legalized cannabis for recreational or medical uses. In this context, cannabis edibles have drawn considerable attention after adverse effects were reported. This paper investigates Twitter users’ perceptions concerning edibles and evaluates the association edibles-related tweeting activity and local cannabis legislation. Methods: Tweets were collected between May 1 and July 31, 2015, using Twitter API and filtered through the eDrugTrends/Twitris platform. A random sample of geolocated tweets was manually coded to evaluate Twitter users’ perceptions regarding edibles. Raw state proportions of Twitter users mentioning edibles were ajusted relative to the total number of Twitter users per state. Differences in adjusted proportions of Twitter users mentioning edibles between states with different cannabis legislation status were assesed via a permutation test. Results: We collected 100,182 tweets mentioning cannabis edibles with 26.9% (n = 26,975) containing state-level geolocation. Adjusted percentages of geolocated Twitter users posting about edibles were significantly greater in states that allow recreational and/or medical use of cannabis. The differences were statistically significant. Overall, cannabis edibles were generally positively perceived among Twitter users despite some negative tweets expressing the unreliability of edible consumption linked to variability in effect intensity and duration. Conclusion: Our findings suggest that Twitter data analysis is an important tool for epidemiological monitoring of emerging drug use practices and trends. Results tend to indicate greater tweeting activity about cannabis edibles in states where medical THC and/or recreational use are legal. Although the majority of tweets conveyed positive attitudes about cannabis edibles, analysis of experiences expressed in negative tweets confirms the potential adverse effects of edibles and calls for educating edibles-naïve users, improving edibles labeling, and testing their THC content.

description: We report on the experimental realization of a robust and efficient magneto-optical trap for erbium atoms, based on a narrow cooling transition at 583nm. We observe up to $N=2 \times 10^{8}$ atoms at a temperature of about $T=15 μK$. This simple scheme provides better starting conditions for direct loading of dipole traps as compared to approaches based on the strong cooling transition alone, or on a combination of a strong and a narrow kHz transition. Our results on Er point to a general, simple and efficient approach to laser cool samples of other lanthanide atoms (Ho, Dy, and Tm) for the production of quantum-degenerate samples.

description: Precision data generally require the threshold for physics beyond the Standard Model to be at the deca-TeV (10 TeV) scale or higher. This raises the question of whether there are interesting deca-TeV models for which the LHC may find direct clues. A possible scenario for such physics is a 5D warped model of fermion masses and mixing, with Kaluza-Klein masses m_KK ~ 10 TeV, allowing it to avoid tension with stringent constraints, especially from flavor data. Discovery of a Standard-Model-like Higgs boson, for which there are some hints at ~125 GeV at the LHC, would also require the KK masses to be at or above 10 TeV. These warped models generically predict the appearance of a much lighter radion scalar. We find that, in viable warped models of flavor, a radion with a mass of a few hundred GeV and an inverse coupling of order m_KK ~ 10 TeV could typically be accessible to the LHC experiments -- with sqrt(s) = 14 TeV and 100 fb^-1 of data. The above statements can be applied, mutatis mutandis, to 4D dual models, where conformal dynamics and a dilaton replace warping and the radion, respectively. Detection of such a light and narrow scalar could thus herald the proximity of a new physical threshold and motivate experiments that would directly probe the deca-TeV mass scale.

description: We determine Lambda_msbar for QCD with n_f=2 dynamical quark flavors by fitting the Q-Q-bar static potential known analytically in the perturbative regime up to terms of O(alpha_s^4) and ~alpha_s^4 ln(alpha_s) to corresponding results obtained from lattice simulations. This has become possible, due to recent advances in both perturbative calculations, namely the determination and publication of the last missing contribution to the Q-Q-bar static potential at O(alpha_s^4), and lattice simulations with n_f=2 dynamical quark flavors performed at the rather fine lattice spacing of a~0.042 fm. Imposing conservative error estimates we obtain Lambda_msbar=315(30) MeV.

description: Let $S(k)$ be the scattering matrix for a Schrödinger operator (Laplacian plus potential) on $\RR^n$ with compactly supported smooth potential. It is well known that $S(k)$ is unitary and that the spectrum of $S(k)$ accumulates on the unit circle only at 1; moreover, $S(k)$ depends analytically on $k$ and therefore its eigenvalues depend analytically on $k$ provided the values stay away from 1. We give examples of smooth, compactly supported potentials on $\RR^n$ for which (i) the scattering matrix $S(k)$ does not have 1 as an eigenvalue for any $k > 0$, and (ii) there exists $k_0 > 0$ such that there is an analytic eigenvalue branch $e^{2iδ(k)}$ of S(k)$ converging to 1 as $k \downarrow k_0$. This shows that the eigenvalues of the scattering matrix, as a function of $k$, do not necessarily have continuous extensions to or across the value 1. In particular this shows that a `micro-Levinson theorem' for non-central potentials in $\RR^3$ claimed in a 1989 paper of R. Newton is incorrect.

description: For dynamical systems modeled by a Young tower with exponential tails, we prove an exponential concentration inequality for all separately Lipschitz observables of n variables.

description: Mary Manning was one of a handful of women active behind the camera in Ireland’s two waves of silent film production. Between 1914 and 1926, a prolific mass-market industry specialized in popular film genres like historical melodramas and romantic comedies and dramas. Ellen O’Mara Sullivan (co-founder of and producer at Film Company of Ireland, 1914-1920), Margaret T. Pender (source writer, O’Neil of the Glen, 1916), Ulster novelist Mrs. N. F. Patton (adapter, Knocknagow, 1918), and Dorothy Donn-Byrne (source writer, Land of Her Fathers, 1925) were the female pioneers in this first wave. Between 1930 and 1935, a second silent industry produced more experimental, less commercial films, extending this second silent era well beyond the 1927 advent of sound in the U.S and much of Europe. In addition to Manning, women filmmakers included Lettice Ramsey and British- born Frances Baker Farrell who designed sets (Some Say Chance, 1934) and Gate Theatre actress Maírín Hayes who edited (Guests of the Nation, 1935). Scholars offer few details on Manning’s contribution in this second wave, though she appears to have been one of the driving forces behind five of the six films produced. In her brief, but significant film career, Manning was a screenwriter, adapter, director, assistant director, and actress who also worked on props and casting. In addition, she was a film critic and a founding member of an art house film society and an amateur filmmaking club.

DISTRIBUTION. — Savu Sea, Indonesia, in 247 m (type locality), and Fiji (new record), shells in 150-295 m. REMARKS. — Daphnellopsis lamellosus differs from D. fimbriatus in having a more elongated, narrow shell with weakly shouldered whorls. The spiral cords are comparatively narrower, more uniform and more widely spaced. The axial lamellae are lower and the teleoconch whorls are comparatively higher. The protoconch is shorter, with flatter whorls. Daphnellopsis lamellosus was until now only known from the type material illustrated by Houart (1995a). The discovery of this species in the Fiji archipelago confirms the differences between the two species, noted by Houart (1995a).

description: Objectives. To assess the association between medical marijuana laws (MMLs) and the odds of a positive opioid test, an indicator for prior use.

Methods. We analyzed 1999–2013 Fatality Analysis Reporting System (FARS) data from 18 states that tested for alcohol and other drugs in at least 80% of drivers who died within 1 hour of crashing (n = 68 394). Within-state and between-state comparisons assessed opioid positivity among drivers crashing in states with an operational MML (i.e., allowances for home cultivation or active dispensaries) versus drivers crashing in states before a future MML was operational.

Results. State-specific estimates indicated a reduction in opioid positivity for most states after implementation of an operational MML, although none of these estimates were significant. When we combined states, we observed no significant overall association (odds ratio [OR] = 0.79; 95% confidence interval [CI] = 0.61, 1.03). However, age-stratified analyses indicated a significant reduction in opioid positivity for drivers aged 21 to 40 years (OR = 0.50; 95% CI = 0.37, 0.67; interaction P

description: In 1919, when Moving Picture World asked her what her work meant, Frances Marion said, “Stories, working scenarios ready for the director to proceed, tarrying with him through every scene as it is filmed; editing and cutting the complete product and title-writing every bit of it.” The native San Franciscan, born Marion Benson Owens, worked in every facet of film production and wrote the stories and scenarios for over three hundred films in a career that spans from early cinema to the sound era and netted her two Academy Awards for screenwriting. Trained by director-producer Lois Weber, Marion worked with nearly every major player over the years, and maintained ongoing collaborations with Mary Pickford, Irving Thalberg, and William Randolph Hearst. She excelled at writing scripts that accentuated the strengths of specific actors and is often credited with defining the careers of Marie Dressler, Greta Garbo, Marion Davies, and Pickford as well as her husband, cowboy star actor Fred Thomson.

description: Background: Increases in illicit pharmaceutical opioid (PO) use have been associated with risk for transition to heroin use. We identify predictors of transition to heroin use among young, illicit PO users with no history of opioid dependence or heroin use at baseline. Methods: Respondent-driven sampling recruited 383 participants; 362 returned for at least one biannual structured interview over 36 months. Cox regression was used to test for associations between lagged predictors and hazard of transition to heroin use. Potential predictors were based on those suggested in the literature. We also computed population attributable risk (PAR) and the rate of heroin transition. Results: Over 36 months, 27 (7.5%) participants initiated heroin use; all were white, and the rate of heroin initiation was 2.8% per year (95% CI = 1.9%–4.1%). Mean length of PO at first reported heroin use was 6.2 years (SD = 1.9). Lifetime PO dependence (AHR = 2.39, 95% CI = 1.07–5.48; PAR = 32%, 95% CI = −2% to 64%), early age of PO initiation (AHR = 3.08, 95%; CI = 1.26–7.47; PAR = 30%, 95% CI = 2%–59%), using illicit POs to get high but not to self-medicate a health problem (AHR = 4.83, 95% CI = 2.11–11.0; PAR = 38%, 95% CI = 12%–65%), and ever using PO non-orally most often (AHR = 6.57, 95% CI = 2.81–17.2; PAR = 63%, 95% CI = 31%–86%) were significant predictors. Conclusion: This is one of the first prospective studies to test observations from previous cross-sectional and retrospective research on the relationship between illicit PO use and heroin initiation among young, initially non-opioid dependent PO users. The results provide insights into targets for the design of urgently needed prevention interventions.

description: We show how correlated steps introduces significant contributions to the modification of the halo mass function in modified gravity models, taking the chameleon models as an example, in the framework of the excursion set approach. This correction applies to both Lagrangian and Eulerian environments discussed in previous studies. Correlated steps also enhances the modifications due to the fifth force in the conditional mass function as well as the halo bias. We found that abundance and clustering measurements from different environments can provide strong constraints on the chameleon models.

description: This paper focuses on the distributed optimization of stochastic saddle point problems. The first part of the paper is devoted to lower bounds for the centralized and decentralized distributed methods for smooth (strongly) convex-(strongly) concave saddle point problems, as well as the near-optimal algorithms by which these bounds are achieved. Next, we present a new federated algorithm for centralized distributed saddle-point problems – Extra Step Local SGD. The theoretical analysis of the new method is carried out for strongly convex-strongly concave and non-convex-non-concave problems. In the experimental part of the paper, we show the effectiveness of our method in practice. In particular, we train GANs in a distributed manner.

description: We formulate an effective theory for systems containing a heavy Majorana fermion, such as bound states of a long-lived gluino. This "Majorana HQET" has the same degrees of freedom as the well-studied Dirac HQET. It respects an emergent U(1) symmetry despite the fundamental absence of a U(1) for Majorana fermions. Reparameterization invariance works identically in the two HQETs. Remarkably, while a Dirac HQET may or may not be charge conjugation symmetric, a charge conjugation symmetry emerges in all Majorana HQETs, potentially offering low energy probes to distinguish the two theories.
