description: We discuss charged lepton flavour violating processes occurring in the presence of muonic atoms, such as muon-electron conversion in nuclei $\text{CR}(μ-e, \text{ N})$, the (Coulomb enhanced) decay of muonic atoms into a pair of electrons BR($μ^- e^- \to e^- e^-$, N), as well as Muonium conversion and decay, $\text{Mu}-\bar{\text{Mu}}$ and $\text{Mu}\to e^+ e^-$. Any experimental signal of these observables calls for scenarios of physics beyond the Standard Model. In this work, we consider minimal extensions of the Standard Model via the addition of sterile fermions, providing the corresponding complete analytical expressions for all the considered observables. We first consider an "ad hoc" extension with a single sterile fermion state, and investigate its impact on the above observables. Two well motivated mechanisms of neutrino mass generation are then considered: the Inverse Seesaw embedded into the Standard Model, and the $ν$MSM. Our study reveals that, depending on their mass range and on the active-sterile mixing angles, sterile neutrinos can give significant contributions to the above mentioned observables, some of them even lying within present and future sensitivity of dedicated cLFV experiments. We complete the analysis by confronting our results to other (direct and indirect) searches for sterile fermions.

description: We study the rheology of confined suspensions of neutrally buoyant rigid monodisperse spheres in plane-Couette flow using Direct Numerical Simulations. We find that if the width of the channel is a (small) integer multiple of the sphere's diameter, the spheres self-organize into two-dimensional layers that slide on each other and the suspension's effective viscosity is significantly reduced. Each two-dimensional layer is found to be structurally liquid-like but their dynamics is frozen in time.

description: Description. Co-use of cannabis and alcohol (either general or simultaneous) represents an increasing public health concern in the US. Cannabis is the most commonly reported co-use substance among college-aged alcohol users, and adults with cannabis use disorder are at an increased risk of developing concurrent alcohol use disorder (for a review, please see (Yurasek et al., 2017)). Importantly, despite evidence that cannabis and alcohol mono-use are associated with depressive symptoms (Kishore et al., 2015; Lev-Ran et al., 2014), a recent review concluded that the effects of co-use on mental health outcomes represents an important open research question (Romaguera et al., 2017). Specifically, it is unclear whether cannabis and alcohol use represent distinct, additive, or interrelated effects on depressive symptoms. Before assembling this secondary data analysis protocol, we tested a mediation model involving cannabis use, alcohol use, and depressive symptoms in an exploratory assessment among young-adults co-users (N = 402). Specifically, we found a positive association between cannabis use and depressive symptoms (Bstandard = .18, 95% CI (.09, .28), p = < .001), a positive association between alcohol use and depressive symptoms (Bstandard = .28, 95% CI (.19, .38), p < .001), and near-complete mediation of the association between cannabis use and depressive symptoms through alcohol use (proportion mediated = .34, 95% CI (.17, .74), p < .001). Objective. a. To test/validate the mediation model described above in a representative national sample. Hypotheses a. There is a positive association between cannabis use and depressive symptoms.* b. There is a positive association between alcohol use and depressive symptoms.* c. The association between cannabis use and depressive symptoms is partially mediated through alcohol use.* *Statistical significance for simple linear models and mediation models will be determined using standard thresholds (α = .05).

description: The field theoretic renormalization group and the operator product expansion are applied to the model of passive vector (magnetic) field advected by a random turbulent velocity field. The latter is governed by the Navier--Stokes equation for compressible fluid, subject to external random force with the covariance $\propto δ(t-t') k^{4-d-y}$, where $d$ is the dimension of space and $y$ is an arbitrary exponent. From physics viewpoints, the model describes magnetohydrodynamic turbulence in the so-called kinematic approximation, where the effects of the magnetic field on the dynamics of the fluid are neglected. The original stochastic problem is reformulated as a multiplicatively renormalizable field theoretic model; the corresponding renormalization group equations possess an infrared attractive fixed point. It is shown that various correlation functions of the magnetic field and its powers demonstrate anomalous scaling behavior in the inertial-convective range already for small values of~$y$. The corresponding anomalous exponents, identified with scaling (critical) dimensions of certain composite fields ("operators" in the quantum-field terminology), can be systematically calculated as series in $y$. The practical calculation is performed in the leading one-loop approximation, including exponents in anisotropic contributions. It should be emphasized that, in contrast to Gaussian ensembles with finite correlation time, the model and the perturbation theory presented here are manifestly Galilean covariant.

description: Laparoscopic sleeve gastrectomy (LSG) has reached wide popularity during the last 15 years, due to the limited morbidity and mortality rates, and the very good weight loss results and effects on comorbid conditions. However, there are concerns regarding the effects of LSG on gastroesophageal reflux disease (GERD). The interpretation of the current evidence is challenged by the fact that the LSG technique is not standardized, and most studies investigate the presence of GERD by assessing symptoms and the use of acid reducing medications only. A few studies objectively investigated gastroesophageal function and the reflux profile by esophageal manometry and 24-h pH monitoring, reporting postoperative normalization of esophageal acid exposure in up to 85% of patients with preoperative GERD, and occurrence of de novo GERD in about 5% of cases. There is increasing evidence showing the key role of the surgical technique on the incidence of postoperative GERD. Main technical issues are a relative narrowing of the mid portion of the gastric sleeve, a redundant upper part of the sleeve (both depending on the angle under which the sleeve is stapled), and the presence of a hiatal hernia. Concomitant hiatal hernia repair is recommended. To date, either medical therapy with proton pump inhibitors or conversion of LSG to laparoscopic Roux-en-Y gastric bypass are the available options for the management of GERD after LSG. Recently, new minimally invasive approaches have been proposed in patients with GERD and hypotensive LES: the LINX® Reflux Management System procedure and the Stretta® procedure. Large studies are needed to assess the safety and long-term efficacy of these new approaches. In conclusion, the recent publication of pH monitoring data and the new insights in the association between sleeve morphology and GERD control have led to a wider acceptance of LSG as bariatric procedure also in obese patients with GERD, as recently stated in the 5th International Consensus Conference on sleeve gastrectomy.

description: At the epoch of decoupling, cosmic baryons had supersonic velocities relative to the dark matter that were coherent on large scales. These velocities subsequently slow the growth of small-scale structure and, via feedback processes, can influence the formation of larger galaxies. We examine the effect of streaming velocities on the galaxy correlation function, including all leading-order contributions for the first time. We find that the impact on the BAO peak is dramatically enhanced (by a factor of ~5) over the results of previous investigations, with the primary new effect due to advection: if a galaxy retains memory of the primordial streaming velocity, it does so at its Lagrangian, rather than Eulerian, position. Since correlations in the streaming velocity change rapidly at the BAO scale, this advection term can cause a significant shift in the observed BAO position. If streaming velocities impact tracer density at the 1% level, compared to the linear bias, the recovered BAO scale is shifted by approximately 0.5%. This new effect, which is required to preserve Galilean invariance, greatly increases the importance of including streaming velocities in the analysis of upcoming BAO measurements and opens a new window to the astrophysics of galaxy formation.

description: We stabilize the idler frequency of a singly-resonant optical parametric oscillator directly to the resonance of a mid-infrared Fabry-Pérot reference cavity. This is accomplished by the Pound-Drever-Hall locking scheme, controlling either the pump laser or the resonant signal frequency. A residual relative frequency noise power spectral density below 10$^3$ Hz$^2$/Hz is reached, with a Gaussian linewidth of 920 Hz over 100 ms, which demonstrates the potential for reaching spectral purity down to the Hz level by locking the optical parametric oscillator against a mid-infrared cavity with state-of-the-art superior performance.

description: Minimal models of active Brownian colloids consisting of self-propelled spherical particles with purely repulsive interactions have recently been identified as excellent quantitative testing grounds for theories of active matter and have been the subject of extensive numerical and analytical investigation. These systems do not exhibit aligned or flocking states, but do have a rich phase diagram, forming active gases, liquids and solids with novel mechanical properties. This article reviews recent advances in the understanding of such models, including the description of the active gas and its swim pressure, the motility-induced phase separation and the high-density crystalline and glassy behavior.

Finite-Size Effects on Traveling Wave Solutions to Neural Field Equations

description: Neural field equations are used to describe the spatio-temporal evolution of the activity in a network of synaptically coupled populations of neurons in the continuum limit. Their heuristic derivation involves two approximation steps. Under the assumption that each population in the network is large, the activity is described in terms of a population average. The discrete network is then approximated by a continuum. In this article we make the two approximation steps explicit. Extending a model by Bressloff and Newby, we describe the evolution of the activity in a discrete network of finite populations by a Markov chain. In order to determine finite-size effects—deviations from the mean-field limit due to the finite size of the populations in the network—we analyze the fluctuations of this Markov chain and set up an approximating system of diffusion processes. We show that a well-posed stochastic neural field equation with a noise term accounting for finite-size effects on traveling wave solutions is obtained as the strong continuum limit.
Effects of Subthalamic Deep Brain Stimulation on Neuropsychiatric Parkinson’s Disease Symptoms by its Impact on Distributed Brain Networks

description: Above and beyond a mere modulation of neuronal activity on a focal level, subthalamic-deep brain stimulation (STN-DBS) unfolds its substantial potential in the therapy of Parkinson’s disease (PD) symptomatology by recalibrating widespread dysfunctional brain networks. Crucially, given the non-monolithic, multisymptomatic disease structure of PD, the optimal therapy of each different symptom domain may require modulating distinct “symptomatotopic” networks. Apart from evidence regarding motor deficits paradigmatic for PD, prior attempts to identify such symptom-specific circuit targets have, however, often neglected the effects of remote connectivity seeding from precisely placed electrodes on the neuropsychiatric symptom spectrum. Within our project, we thus aim at leveraging DBS network mapping by combining patient-specific electrode locations derived from magnetic resonance imaging (MRI) and computer tomography with a normative PD connectome (diffusion-weighted tractography and resting state functional MRI). Based on these training data, we strive to model and cross-validate segregated symptom-specific, structural and functional connectivity profiles passing by STN-DBS electrode stimulation sites, which are predictive of patients’ improvement or worsening in neuropsychiatric assessments. We will perform parameter optimization and model selection on a training and cross-validation set and validate final results in a left-out independent test dataset. Secondly, by integrating these domain-specific beneficial and detrimental connectivity profiles into a convergent circuit target model which can be weighted by individual intensities of symptom constellations, we hope to pave the way towards personalized precision neuromodulation targeting.

description: Background In 2002, Disease Management Programs (DMPs) were introduced within the German healthcare system with the aim to increase the quality of chronic disease care. Due to the enrollment procedures, it can be assumed a) that only certain patients actively decide to enroll in a DMP and/or b) that only certain patients get the recommendation for DMP enrollment from their physician. How strong this assumed effect of self- and/or professional selection is, is still unclear. Methods We used data from a cross-sectional postal-survey linked on individual level with administrative claims data from a German sickness fund. The sample consisted of individuals suffering from coronary heart disease (CHD) who i) were either enrolled in the respective DMP or ii) fulfilled the disease related criteria for enrollment but were not enrolled. We applied multivariate logistic regression analyses to assess factors on patient level associated with DMP enrollment. Results We included 7070 individuals in our analyses. Male sex, higher age and receiving old age pension, a higher Charlson Score and a diagnosis of type 2 diabetes increased the odds for DMP-CHD enrollment significantly. Individuals with a diagnosed myocardial infarction (MI) were also more likely to be enrolled in the DMP-CHD. We found a significant interaction effect for MI and sex, indicating that the association between MI and DMP enrollment is stronger for women than for men. Conclusion DMP-enrollees and non-enrollees differ in various factors. Studies analyzing the effectiveness of DMP-CHD should carefully take into account these group differences. Furthermore, the results suggest that the DMP-CHD assessed reaches men better than women.
Centrosomes are multifunctional regulators of genome stability

Year: 2016

description: The maintenance of genome stability is critical for proper cell function, and loss of this stability contributes to many human diseases and developmental disorders. Therefore, cells have evolved partially redundant mechanisms to monitor and protect the genome. One subcellular organelle implicated in the maintenance of genome stability is the centrosome, best known as the primary microtubule organizing center of most animal cells. Centrosomes serve many different roles throughout the cell cycle, and many of those roles, including mitotic spindle assembly, nucleation of the interphase microtubule array, DNA damage response, and efficient cell cycle progression, have been proposed to help maintain genome stability. As a result, the centrosome is itself a highly regulated entity. Here, we review evidence concerning the significance of the centrosome in promoting genome integrity. Recent advances permitting acute and persistent centrosome removal suggest we still have much to learn regarding the specific function and actual importance of centrosomes in different contexts, as well as how cells may compensate for centrosome dysfunction to maintain the integrity of the genome. Although many animal cells survive and proliferate in the absence of centrosomes, they do so aberrantly. Based on these and other studies, we conclude that centrosomes serve as critical, multifunctional organelles that promote genome stability.

description: Abstract The aim is to analyze upper limb functioning and disability, and its association with health-related quality of life among artisanal fisherwomen from Bahia, Brazil. Cross-sectional epidemiological study was conducted with a sample of 209 fisherwomen. Structured questionnaires were used for socio-demographic and comorbidity information, as well as the instruments Disabilities of the Arm, Shoulder and Hand (DASH) and Short-Form Healthy Survey (SF-36) respectively, to evaluate the upper limbs and health-related quality of life. The results demonstrated that the presence of musculoskeletal disorders in the upper limbs directly affects the values of the DASH instrument and the SF-36v01 questionnaire scores, while also generating a negative correlation between the DASH and SF-36v01. The varying functioning abilities, pain and social aspects negatively affect upper limb function, and the daily activities and work of fisherwomen. The presence of chronic disease and the absence of intervention and rehabilitation for these professionals, that could produces, in a long-term, cases of disability.

description: We present a magnetometer based on optically pumped Cs atoms that measures the magnitude and direction of a 1 $μ$T magnetic field. Multiple circularly polarized laser beams were used to probe the free spin precession of the Cs atoms. The design was optimized for long-time stability and achieves a scalar resolution better than 300 fT for integration times ranging from 80 ms to 1000 s. The best scalar resolution of less than 80 fT was reached with integration times of 1.6 to 6 s. We were able to measure the magnetic field direction with a resolution better than 10 $μ$rad for integration times from 10 s up to 2000 s.

description: General genealogical processes such as $Λ$- and $Ξ$-coalescents, which respectively model multiple and simultaneous mergers, have important applications in studying marine species, strong positive selection, recurrent selective sweeps, strong bottlenecks, large sample sizes, and so on. Recently, there has been significant progress in developing useful inference tools for such general models. In particular, inference methods based on the site frequency spectrum (SFS) have received noticeable attention. Here, we derive a new formula for the expected SFS for general $Λ$- and $Ξ$-coalescents, which leads to an efficient algorithm. For time-homogeneous coalescents, the runtime of our algorithm for computing the expected SFS is $O(n^2)$, where $n$ is the sample size. This is a factor of $n^2$ faster than the state-of-the-art method. Furthermore, in contrast to existing methods, our method generalizes to time-inhomogeneous $Λ$- and $Ξ$-coalescents with measures that factorize as $Λ(dx)/ζ(t)$ and $Ξ(dx)/ζ(t)$, respectively, where $ζ$ denotes a strictly positive function of time. The runtime of our algorithm in this setting is $O(n^3)$. We also obtain general theoretical results for the identifiability of the $Λ$ measure when $ζ$ is a constant function, as well as for the identifiability of the function $ζ$ under a fixed $Ξ$ measure.

description: The purpose of this paper is to explore practical issues in developing and implementing a culturally tailored Internet Cancer Support Group for a group of ethnic minority cancer patients—Asian American cancer patients. Throughout the research process of the original study testing the Internet cancer support group, research team made written records of practical issues and plausible rationales for the issues. Weekly group discussion among research team members was conducted, and the discussion records were evaluated and analyzed using a content analysis (with individual words as the unit of analysis). The codes from the analysis process were categorized into idea themes, through which the issues were extracted. The issues included those in: (a) difficulties in using multiple languages; (b) collaboration with the IT department and technical challenges (c) difficulties in recruitment; (d) difficulties in retention; (e) optimal timing; and (f) characteristics of the users. Based on the findings, we suggested researchers to plan a workable translation process, check technical needs in advance, use multiple strategies to recruit and retain research participants, plan the right time for data collection, and consider characteristics of the users in the study design.

description: We study the average value of the divisor function $τ(n)$ for $n\le x$ with $n \equiv a \bmod q$. The divisor function is known to be evenly distributed over arithmetic progressions for all $q$ that are a little smaller than $x^{2/3}$. We show how to go past this barrier when $q=p^k$ for odd primes $p$ and any fixed integer $k\ge 7$.

description: BACKGROUND: Cangrelor is an intravenous P2Y12 inhibitor approved to reduce periprocedural ischemic events in patients undergoing percutaneous coronary intervention not pretreated with a P2Y12 inhibitor.

METHODS: A total of 11 145 patients were randomized to cangrelor or clopidogrel in the CHAMPION PHOENIX trial (Cangrelor versus Standard Therapy to Achieve Optimal Management of Platelet Inhibition). We explored the effects of cangrelor on myocardial infarction (MI) using different definitions and performed sensitivity analyses on the primary end point of the trial.

RESULTS: A total of 462 patients (4.2%) undergoing percutaneous coronary intervention had an MI as defined by the second universal definition. The majority of these MIs (n=433, 93.7%) were type 4a. Treatment with cangrelor reduced the incidence of MI at 48 hours (3.8% versus 4.7%; odds ratio [OR], 0.80; 95% confidence interval [CI], 0.67-0.97; P=0.02). When the Society of Coronary Angiography and Intervention definition of periprocedural MI was applied to potential ischemic events, there were fewer total MIs (n=134); however, the effects of cangrelor on MI remained significant (OR, 0.65; 95% CI, 0.46-0.92; P=0.01). Similar effects were seen in the evaluation of the effects of cangrelor on MIs with peak creatinine kinase-MB ≥10 times the upper limit of normal (OR, 0.64; 95% CI, 0.45-0.91) and those with peak creatinine kinase-MB ≥10 times the upper limit of normal, ischemic symptoms, or ECG changes (OR, 0.63; 95% CI, 0.48-0.84). MIs defined by any of these definitions were associated with increased risk of death at 30 days. Treatment with cangrelor reduced the composite end point of death, MI (Society of Coronary Angiography and Intervention definition), ischemia-driven revascularization, or Academic Research Consortium definite stent thrombosis (1.4% versus 2.1%; OR, 0.69; 95% CI, 0.51-0.92).

CONCLUSIONS: MI in patients undergoing percutaneous coronary intervention, regardless of definition, remains associated with increased risk of death in the current era. Cangrelor compared with clopidogrel significantly reduces MI regardless of the definition.

description: Intrinsic alignment (IA) of source galaxies is one of the major astrophysical systematics for ongoing and future weak lensing surveys. This paper presents the first forecasts of the impact of IA on cosmic shear measurements for current and future surveys (DES, Euclid, LSST, WFIRST) using simulated likelihood analyses and realistic covariances that include higher-order moments of the density field in the computation. We consider a range of possible IA scenarios and test mitigation schemes, which parameterize IA by the fraction of red galaxies, normalization, luminosity and redshift dependence of the IA signal (for a subset we consider joint IA and photo-z uncertainties). Compared to previous studies we find smaller biases in time-dependent dark energy models if IA is ignored in the analysis; the amplitude and significance of these biases vary as a function of survey properties (depth, statistical uncertainties), luminosity function, and IA scenario: Due to its small statistical errors and relatively shallow observing strategy Euclid is significantly impacted by IA. LSST and WFIRST benefit from their increased survey depth, while the larger statistical errors for DES decrease IA's relative impact on cosmological parameters. The proposed IA mitigation scheme removes parameter biases due to IA for DES, LSST, and WFIRST even if the shape of the IA power spectrum is only poorly known; successful IA mitigation for Euclid requires more prior information. We explore several alternative IA mitigation strategies for Euclid; in the absence of alignment of blue galaxies we recommend the exclusion of red (IA contaminated) galaxies in cosmic shear analyses. We find that even a reduction of 20% in the number density of galaxies only leads to a 4-10% loss in cosmological constraining power.

description: Quasifission is the primary reaction mechanism that limits the formation of superheavy nuclei and consequently an important ingredient for choosing the best target-projectile combinations for the heavy element searches. Quasifission is characterized by nuclear contact-times that are much longer than those found in deep-inelastic reactions, resulting in a substantial mass and charge transfer. In this manuscript we employ the fully microscopic time-dependent Hartree-Fock (TDHF) theory to study quasifission. New results are presented for the $^{48}$Ca+$^{249}$Bk system.
