description: Objectives. We have described the epidemiology of co-occurring lower respiratory symptoms (LRS) and probable posttraumatic stress disorder (PTSD) 5 to 6 years after exposure to the 9/11 disaster.

Methods. We analyzed residents, office workers, and passersby (n = 16 363) in the World Trade Center Health Registry. Using multivariable logistic regression, we examined patterns of reported respiratory symptoms, treatment sought for symptoms, diagnosed respiratory conditions, mental health comorbidities, quality of life, and unmet health care needs in relation to comorbidity.

Results. Among individuals with either LRS or PTSD, 24.6% had both conditions. The odds of comorbidity was significantly higher among those with more severe 9/11 exposures. Independent of 9/11 exposures, participants with LRS had 4 times the odds of those without it of meeting criteria for PTSD, and those with PTSD had 4 times the odds of those without it of meeting criteria for LRS. Participants with comorbidity had worse quality of life and more unmet mental health care needs than did all other outcome groups.

Conclusions. Respiratory and mental illness are closely linked in individuals exposed to 9/11 and should be considered jointly in public health outreach and treatment programs

description: We study the isovalent substitution effect by partially introducing Se on S site in the newly discovered superconductor Nb$_2$PdS$_5$ ($T_c\sim$6 K) whose upper critical field is found to be far above its Pauli paramagnetic limit. In this Nb$_2$Pd(S$_{1-x}$Se$_x$)$_5$ (0$\leq$$x$$\leq$0.8) system, superconductivity is systematically suppressed by the Se concentration and ultimately disappears when $x\geq$ 0.5, after which a semiconducting-like ground state emerges. In spite of the considerably reduced $T_c$ with Se doping, the ratio of the upper critical field $H_{c2}$ to $T_c$, remains unaffected. Moreover, the size of the heat capacity jump at $T_c$ is smaller than that expected for a BCS superconductor, implying that a strong-coupling theory cannot be the origin of this large upper critical field. In addition, the low-lying quasiparticle excitations are consistent with a nodeless gap opening over the Fermi surface. These results combined impose severe constraints on any theory of exotic superconductivity in this system.

description: Background
Serious respiratory illnesses have been reported among rescue/recovery workers (RRW) following the World Trade Center (WTC) attacks.

Methods
We studied RRW enrolled in the WTC Health Registry to assess the effects of different respiratory protection equipment (RPE) types on respiratory outcomes, such as recurrent respiratory symptoms and diseases possibly associated with 9/11 exposures. We performed descriptive and multivariate analyses adjusting for demographics and exposure variables.

Results
A total of 9,296 RRW met inclusion criteria. The strongest predictors of using adequate RPE were being affiliated with construction, utilities or environmental remediation organizations and having received RPE training. Workers who used respirators were less likely to report adverse respiratory outcomes compared to those who reported no/lower levels of respiratory protection.

Conclusions
Level of respiratory protection was associated with the odds of reporting respiratory symptoms and diseases. Training, selection, fit testing, and consistent use of RPE should be emphasized among emergency responders.

description: In a case-control study of 302 male and 65 female bladder cancer patients and an equal number of other patients matched to them in age, sex, hospital, and hospital-room status, no association was found between use of artificial sweeteners or diet beverages and bladder cancer. No dose-response was observed with respect to quantity or duration of use or the two combined. No evidence was found to suggest that artificial sweeteners or diet beverages promote the tumorigenic effect of tobacco smoking. Artificial sweetener and diet beverage use strongly reflected socioeconomic status among controls with various diagnoses.

description: We study the competing effects of simultaneous Markovian and non-Markovian decoherence mechanisms acting on a single spin. We show the existence of a threshold in the relative strength of such mechanisms above which the spin dynamics becomes fully Markovian, as revealed by the use of several non-Markovianity measures. We identify a measure-dependent nested structure of such thresholds, hinting at a causality relationship amongst the various non-Markovianity witnesses used in our analysis. Our considerations are then used to argue the unavoidably non-Markovian evolution of a single-electron quantum dot exposed to both intrinsic and Markovian technical noise, the latter of arbitrary strength.

description: Extratropical cyclones play a principal role in wintertime precipitation and severe weather over North America. On average, the greatest number of cyclones track 1) from the lee of the Rocky Mountains eastward across the Great Lakes and 2) over the Gulf Stream along the eastern coastline of North America. However, the cyclone tracks are highly variable within individual winters and between winter seasons. In this study, the authors apply a Lagrangian tracking algorithm to examine variability in extratropical cyclone tracks over North America during winter. A series of methodological criteria is used to isolate cyclone development and decay regions and to account for the elevated topography over western North America. The results confirm the signatures of four climate phenomena in the intraseasonal and interannual variability in North American cyclone tracks: the North Atlantic Oscillation (NAO), the El Niño–Southern Oscillation (ENSO), the Pacific–North American pattern (PNA), and the Madden–Julian oscillation (MJO). Similar signatures are found using Eulerian bandpass-filtered eddy variances. Variability in the number of extratropical cyclones at most locations in North America is linked to fluctuations in Rossby wave trains extending from the central tropical Pacific Ocean. Only over the far northeastern United States and northeastern Canada is cyclone variability strongly linked to the NAO. The results suggest that Pacific sector variability (ENSO, PNA, and MJO) is a key contributor to intraseasonal and interannual variability in the frequency of extratropical cyclones at most locations across North America.

description: But de l’étude : Cette étude vise à décrire le processus de transition expérimenté par les nouveaux résidents dans un établissement médico-social (EMS) au travers d’une perspective transactionnelle. Méthodologie : Une étude de la portée a été retenue pour l’élaboration de notre étude. Le cadre de référence d’Arksey & O’Malley a été utilisé (Arksey & O’Malley, 2005). Neuf articles ont été sélectionnés et analysés. Résultats : Les résultats sont présentés de manière analytique et thématique afin de présenter un compte rendu narratif de la littérature. L’assemblage et la synthèse des données ont permis de ressortir les thèmes suivants : l’influence des occupations, de l’environnement, du contexte et de l’accompagnement, le tout dans le cadre de la transition occupationnelle lors de l’entrée en EMS. Ceux-ci sont analysés à l’aide de plusieurs sous-sujets. Discussion : Une posture réflexive concernant les enjeux socio-démographiques de la population vieillissante en Suisse et dans d’autres pays est mise en avant. Cette considération permet de faire émerger des thèmes abordés dans la discussion comme la communication, la multiplicité des acteurs ou encore les mouvements de population et leurs besoins intrinsèques. Conclusion : Cette étude permet de faire un état des lieux concernant la transition occupationnelle que peuvent expérimenter les nouveaux résidents en EMS. Face à la diversité des enjeux inhérents à cette transition notre travail permet de mettre en lumière l'importance d'une prise en charge personnalisée dans laquelle peut s’insérer une approche en ergothérapie.

This class includes the Dirichlet Laplacian, the fractional Laplacian, and also fractional differential operators with non-homogeneous symbols. Based on a sharp estimate for the sum of the eigenvalues we establish the first term of the semiclassical asymptotics. This generalizes Weyl's law for the Laplace operator.

description: We present BV photometry for 54 variables in the metal-rich inner halo globular cluster NGC6723. With the discovery of new RR Lyrae variables (RRLs), we obtain = 0.541 +/- 0.066 and = 0.292 +/- 0.030 day, n(c)/n(ab+c) = 0.167, and _int = 15.459 +/- 0.055. We carry out the Fourier decomposition analysis and obtain [Fe/H]_ZW = -1.23 +/- 0.11 and E(B-V) = 0.063 +/- 0.015 for NGC 6723. By calibrating the zero-point from the recent absolute trigonometric parallax measurements for RR Lyr, we derive the revised M_V(RR)-[Fe/H] relation, providing M_V(RR)= 0.52 at [Fe/H] = -1.50 and (m-M)_0 = 18.54 for Large Magellanic Cloud (LMC), in excellent agreement with others. We obtain (m-M)_0 = 14.65 +/- 0.05, equivalent to the distance from the Sun of 8.47 +/- 0.17 kpc, for NGC 6723 from various distance measurement methods using RRLs. We find that RRLs in NGC 6723 do not have magnitude dependency on the radial distance, due to a not severe degree of the apparent crowdedness. Finally, we show that there exists a relation between the degree of photometric contamination and the apparent crowdedness of the central region of globular cluster systems. The use of this relation can play a significantly role on mitigating the discrepancy to establish a cosmic distance scale using RRLs in resolved stellar populations in the near-field cosmology.

We have recently developed and tested a functional for the averaged radial distribution function at contact of the hard-sphere fluid that is dramatically more accurate at interfaces than earlier approximations. We now incorporate this improved functional into the association term of our free energy functional for water, improving its description of hydrogen bonding. We examine the effect of this improvement by studying two hard solutes: a hard hydrophobic rod and a hard sphere. The improved functional leads to a moderate change in the density profile and a large decrease in the number of hydrogen bonds broken in the vicinity of the solutes.We present a modification to our recently published SAFT-based classical density functional theory for water.

description: This report looks at the ways that credit-based transition programs (CBTPs) may help middle and low-achieving students enter and succeed in college. It highlights promising practices used by CBTPs to help students who might have been considered noncollege-bound prepare for college credit course work. The report also discusses the challenges that CBTPs face when trying to include such students. This report is the final report from the Accelerating Student Success Through Credit-Based Transition Programs study, which was initiated by the U.S. Department of Education, Office of Vocational and Adult Education (OVAE) in the fall of 2003. The goal of the study is to better understand the characteristics of CBTPs and the students they serve. These programs, such as Tech-Prep, dual or concurrent enrollment, International Baccalaureate (IB) and Middle College High School (MCHS), allow high school students to take college-level classes and earn college credit. They sometimes also provide services to support the main aspects of the high school-to-college transition. CBTPs are widespread and interest in them by policymakers, educators, parents, and students has increased in recent years. In addition, while these programs are not new, the idea that they should be accessible to a broader range of students is a new approach. In the past, CBTPs enrolled primarily academically proficient and high-achieving students. Today, however, a growing number of policymakers, education reform groups, and researchers argue that middle- and even low-achieving high school students may benefit from participation in these programs.

description: Context: User-Centered Design and Agile methodologies focus on human issues. Nevertheless, agile methodologies focus on contact with contracting customers and generating value for them. Usually, the communication between end users and the agile team is mediated by customers. However, they do not know the problems end users face in their routines. Hence, UX issues are typically identified only after the implementation, during user testing and validation. Objective: Aiming to improve the understanding and definition of the problem in agile projects, this research investigates the practices and difficulties experienced by agile teams during the development of data science and process automation projects. Also, we analyze the benefits and the teams' perceptions regarding user participation in these projects. Method: We collected data from four agile teams in an academia-industry collaboration focusing on delivering data science and process automation solutions. Therefore, we applied a carefully designed questionnaire answered by developers, scrum masters, and UX designers. In total, 18 subjects answered the questionnaire. Results: From the results, we identify practices used by the teams to define and understand the problem and to represent the solution. The practices most often used are prototypes and meetings with stakeholders. Another practice that helped the team to understand the problem was using Lean Inceptions. Also, our results present some specific issues regarding data science projects. Conclusion: We observed that end-user participation can be critical to understanding and defining the problem. They help to define elements of the domain and barriers in the implementation. We identified a need for approaches that facilitate user-team communication in data science projects and the need for more detailed requirements representations to support data science solutions.

description: Many risk factors for breast cancer are known, but each makes a relatively small contribution to individual risk. Nearly a dozen risk factors taken together accounted for only about 25% of total risk in a population of 570,000 women enrolled in the American Cancer Society's Cancer Prevention Study I (1959-66). This study was considered path-breaking in 1982. Nevertheless, breast cancer remains the leading cause of cancer in US women three decades later.

description: Aims. To validate the Einstein equivalence principle (local position invariance) by limiting the fractional changes in the electron-to-proton mass ratio, mu = m_e/m_p, measured in Galactic plane objects. Methods. High resolution spectral observations of dark clouds in the inversion line of NH3(1,1) and pure rotational lines of other molecules (the so-called ammonia method) were performed at the Medicina 32-m and the Effelsberg 100-m radio telescopes to measure the radial velocity offsets, Delta RV = V_rot - V_inv, between the rotational and inversion transitions which have different sensitivities to the value of mu. Results. In our previous observations (2008-2010), a mean offset of = 0.027+/-0.010 km/s [3 sigma confidence level (C.L.)] was measured. To test for possible hidden errors, we carried out additional observations of a sample of molecular cores in 2010-2013. As a result, a systematic error in the radial velocities of an amplitude ~0.02 km/s was revealed. The averaged offset between the radial velocities of the rotational transitions of HC3N(2-1), HC5N(9-8), HC7N(16-15), HC7N(21-20), and HC7N(23-22), and the inversion transition of NH3(1,1) = 0.003+/-0.018 km/s (3 sigma C.L.). This value, when interpreted in terms of Delta mu/mu= (mu_obs - mu_lab)/mu_lab, constraints the mu-variation at the level of Delta mu/mu < 2*10^{-8} (3 sigma C.L.), which is the most stringent limit on the fractional changes in mu based on astronomical observations.

description: We present a novel estimate of the cosmological microwave background (CMB) map by combining the two latest full-sky microwave surveys: WMAP nine-year and Planck PR1. The joint processing benefits from a recently introduced component separation method coined "local-generalized morphological component analysis'' (LGMCA) based on the sparse distribution of the foregrounds in the wavelet domain. The proposed estimation procedure takes advantage of the IRIS 100 micron as an extra observation on the galactic center for enhanced dust removal. We show that this new CMB map presents several interesting aspects: i) it is a full sky map without using any inpainting or interpolating method, ii) foreground contamination is very low, iii) the Galactic center is very clean, with especially low dust contamination as measured by the cross-correlation between the estimated CMB map and the IRIS 100 micron map, and iv) it is free of thermal SZ contamination.

Our approach will combine analytic properties of the time-like Liouville structure constants, together with the recursive formula of the Virasoro conformal blocks. Although the Coulomb Gas formalism forces a diagonal coupling between the chiral and antichiral sectors of the Conformal Field Theory (CFT), we present new results for the multi-screening integrals which are potentially interesting for applications to critical statistical systems described by Logarithmic CFTs. In particular our findings extend and complement previous results, derived with Coulomb Gas methods, at $c=0$ and $c=-2$.

description: Background
Co-occurrence of lower respiratory symptoms (LRS) and posttraumatic stress disorder (PTSD) has been increasingly recognized among responders and survivors of the World Trade Center (WTC) disaster. Information is limited on the degree which comorbidity intensifies symptoms and compromises quality of life across exposed groups.

Methods
Among responders who completed the first and second Registry surveys, measures of respiratory illness, psychological distress, and diminished quality of life were compared between responders comorbid for LRS and PTSD and responders with only LRS or PTSD.

Results
Of 14,388 responders, 40% of those with LRS and 57% of those with PTSD were comorbid. When demographic and WTC exposure-related factors were controlled, comorbid responders compared to those with LRS alone were twice as likely to have frequent dyspnea and to have sought care for dyspnea. Compared to responders with PTSD alone, comorbid responders were 2.1 times more likely to report intense re-experiencing of the disaster, 2.5 times more likely to express feelings of significant non-specific psychological distress, and 1.4 times more likely to have received mental health care. Comorbid responders were approximately three times more likely to report only fair or poor general health and more than twice as likely to report being unable to perform usual activities for ≥14 of 30 days before interview.

Conclusions
Outcomes in comorbid responders were similar to or more severe than in comorbid survivors. Health care and disaster relief providers must suspect comorbid illness when evaluating responders' respiratory or mental illnesses and consider treatment for both.
A Law Student Says "No" to Freezing Her Eggs

description: Tick-tock goes our biological clocks. A law professor who I admire greatly, only half-jokingly said to my class that the new gift for women graduating from law school would be our parents paying for us to freeze our eggs. The look on my fellow female classmates’ faces was a mixture of relief and panic. That moment was simply an illustration of what we were already thinking and talking about. These are the conversations that highly educated and accomplished women are having today. It is not an exaggeration to state that the majority of time when we discuss our future legal careers we are simultaneously wondering whether we will find someone to marry and when and/or if we are going to have children. For those who are married the conversation focuses on putting off childbirth, fearing that it would interfere with their careers. My classmates who are dating question whether their significant other will propose and how much time they can justifiably allocate to waiting. Lastly, for those that are single, anxiety increases as both statistics and anecdotes affirm that highly educated women are less likely to get married. This anxiety is further exasperated by our “standards.” We seek partners who are equally educated and partners that will also share our views on families, or more specifically when to have children. Bring egg freezing to the table and the women in law school breathe a sigh of relief. It gives us more time, it takes the pressure off, and we don’t have to worry about that pesky career/childrearing balance. However, egg freezing frees us from our concerns only because we often do not and are not meant to understand the dangers of the procedure. Firstly, the fertility industry has downplayed the risks associated with egg retrieval, the drugs that are used to hyperstimulate our ovaries, and the transvaginal aspiration needed to retrieve our eggs.[1][2][3]Secondly, the statistical chance of freezing eggs, fertilizing them in the future, and then having a successful implantation remain relatively low.[4]Fertility companies are profiting off of the anxiety of educated women. Aside from the potential medical issues, it’s concerning that society is constantly inundating us with different values we are encouraged to ascribe to. The “women can have it all,” “women can’t have it all,” “lean in,” “lean out,” mantras we throw around in our regular conversations oppress the ability of women to make choices for themselves. There will always be women who choose to stay home, mothers who work, and those who choose not to have children. However, when companies such as Apple, Facebook, and Citigroup provide “benefits” to women to freeze their eggs they send a clear message that educated and successful women should put off childbirth. Messages like this prevent women from thinking for themselves about what they personally want and further feed into the personal and societal angst we have regarding our biological clocks.

description: In order to figure out and to forecast the emergence phenomena of social systems, we propose several probabilistic models for the analysis of financial markets, especially around a crisis. We first attempt to visualize the collective behaviour of markets during a financial crisis through cross-correlations between typical Japanese daily stocks by making use of multi- dimensional scaling. We find that all the two-dimensional points (stocks) shrink into a single small region when a economic crisis takes place. By using the properties of cross-correlations in financial markets especially during a crisis, we next propose a theoretical framework to predict several time-series simultaneously. Our model system is basically described by a variant of the multi-layered Ising model with random fields as non-stationary time series. Hyper-parameters appearing in the probabilistic model are estimated by means of minimizing the 'cumulative error' in the past market history. The justification and validity of our approaches are numerically examined for several empirical data sets.

description: We present an accurate lattice QCD computation of the b-quark mass, the B and Bs decay constants, the B-mixing bag-parameters for the full four-fermion operator basis, as well as estimates for ξand f_{Bq}\sqrt{B_q} extrapolated to the continuum limit and the physical pion mass. We have used Nf = 2 dynamical quark gauge configurations at four values of the lattice spacing generated by ETMC. Extrapolation in the heavy quark mass from the charm to the bottom quark region has been carried out using ratios of physical quantities computed at nearby quark masses, having an exactly known infinite mass limit.

description: In this paper we present a characterization of the symmetric rotational periodic gravity water waves of finite depth and without stagnation points in terms of the underlying flow. Namely, we show that such a wave is symmetric and has a single crest and trough per period if and only if there exists a vertical line within the fluid domain such that all the fluid particles located on that line minimize there simultaneously their distance to the fluid bed as they move about. Our analysis uses the moving plane method, sharp elliptic maximum principles, and the principle of analytic continuation.

The Impact of Investment Treaties on Governance of Private Investment in Infrastructure

description: Governments are increasingly turning to the private sector to provide the capital, resources and/or know-how necessary for development and operation of infrastructure. In some cases, the involvement by the private sector will trigger coverage by an international investment treaty that overlies, and can override, the domestic law and contract that would otherwise be applicable to the project. This paper discusses the circumstances affecting when an investment treaty will apply and also highlights some of the ways that investment treaties can impact governance of infrastructure development and operation. While focusing on the relationship between investment treaties and investments in infrastructure, this paper is also relevant for the connections between investment treaties and other activities involving investor-state contracts (or quasi-contractual relationships) such as investments in the extractive industries.
High temperature non-collinear magnetism in a classical bilinear-biquadratic Heisenberg model

description: Motivated by the magnetically-driven high-temperature ferroelectric behavior of CuO and the subsequent theoretical efforts to understand this intriguing phenomenon, we study a spin model on a two-dimensional square lattice which possesses some of the key features of the models proposed for CuO. The model consists of Heisenberg couplings between nearest and next-nearest neighbor spins, and biquadratic couplings between nearest neighbors. We use a combination of variational calculations and classical Monte Carlo simulations to study this model at zero and finite temperatures. We show that even an arbitrarily weak biquadratic coupling plays a crucial role in selecting the magnetic ground state. More importantly, a non-collinear magnetic state, characterized by a finite spin current, is stable at finite temperatures. The interesting aspect is that the present model neither includes an inversion-symmetry-breaking term nor the effects of lattice distortions in the Hamiltonian. We conclude that non-collinear magnetism at high temperatures, as observed in CuO, can be explained via pure spin Hamiltonians. We find that the spiral phase is inhomogeneous, and is stabilized by entropic effects. Our study demonstrates that higher order interaction terms are of crucial importance if the stronger interactions together with the lattice geometry contemplate to generate a near degeneracy of magnetic states. The conclusions presented in this work are of particular relevance to the non-collinear magnetism and ferroelectricity observed at high temperatures in cupric oxide.

The Concept of Place Value

description: Motivation and aim of this paper An insufficient development of place value understanding is one of the main causes of mathematical weakness. Even though children already need a place value understanding from Grade 1 on (e.g., interpreting the number symbol 14 as 1 bundle of tens and 4 ones), many children in upper primary and junior secondary school still struggle with place value (e.g., with decimal numbers). Reading research publications indicates that researchers use different terminology when discussing place value, and this can cause misunderstanding for teachers. For example, Ross (1989) states four “properties of our numeration system” that concern place value: (1) the positional property; (2) the base-ten property; (3) the multiplicative property; and (4) the additive property. Houdement and Tempier (2019) indicate that the essence of place value is the juxtaposition of digits, which enables the representation of any quantity, regardless of its size, and that within this representation each individual digit also denotes a quantity. The starting point for Houdement and Tempier is the notion of unit, the foundation of all number systems, where (in the decimal system) ten ones1 form a new unit: one ten... and so on. Bailey (2015) indicates that a fundamental notion of base ten place value is the integration of early experiences of counting by ones and grouping numbers in tens; and later linking these groupings to the corresponding written numeral and how numbers are said. In our view, any of the existing accounts of what constitutes place value understanding is incomplete in some way and has led us to the point where we feel that there is an important need to clarify the concept of place value. In this regard, the aims of this paper are:
 • to clarify the concept of place value; • to distinguish the overarching concept of place value from prerequisite knowledge and from several sub-concepts of the concept of place value; and • to propose a way to develop a connected understanding of place value.

description: Transformer models have achieved state-of-the-art performance on various domains of applications and gradually becomes the foundations of the advanced large deep learning (DL) models. However, how to train these models over multiple GPUs efficiently is still challenging due to a large number of parallelism choices. Existing DL systems either rely on manual efforts to make distributed training plans or apply parallelism combinations within a very limited search space. In this approach, we propose Galvatron, a new system framework that incorporates multiple popular parallelism dimensions and automatically finds the most efficient hybrid parallelism strategy. To better explore such a rarely huge search space, we 1) involve a decision tree to make decomposition and pruning based on some reasonable intuitions, and then 2) design a dynamic programming search algorithm to generate the optimal plan. Evaluations on four representative Transformer workloads show that Galvatron could perform automatically distributed training with different GPU memory budgets. Among all evluated scenarios, Galvatron always achieves superior system throughput compared to previous work with limited parallelism.

description: Biofilms are structured communities of bacteria that play a major role in the pathogenicity of bacteria and are the leading cause of antibiotic resistant bacterial infections on indwelling catheters and medical prosthetic devices. Failure to resolve these biofilm infections may necessitate the surgical removal of the prosthetic device which can be debilitating and costly. Recent studies have shown that application of surface acoustic waves to catheter surfaces can reduce the incidence of infections by a mechanism that has not yet been clarified. We report here the effects of surface acoustic waves (SAW) on the capacity of human neutrophils to eradicate S. epidermidis bacteria in a planktonic state and within biofilms. Utilizing a novel fibrin gel system that mimics a tissue-like environment, we show that SAW, at an intensity of 0.3 mW/cm², significantly enhances human neutrophil killing of S. epidermidis in a planktonic state and within biofilms by enhancing human neutrophil chemotaxis in response to chemoattractants. In addition, we show that the integrin CD18 plays a significant role in the killing enhancement observed in applying SAW. We propose from out data that this integrin may serve as mechanoreceptor for surface acoustic waves enhancing neutrophil chemotaxis and killing of bacteria.
