description: Active flow control of the flow past a cylinder under Reynolds number variation using deep reinforcement learning This study is published in German! In a 2D cylinder flow, a Kármán vortex street is created in the wake of the cylinder, which causes oscillating forces on the cylinder. An agent trained with a deep reinforcement learning algorithm is designed to reduce these forces. To achieve this, the agent rotates the cylinder based on the pressure values on the cylinder surface and thus actively regulates the flow. This algorithm uses a probability distribution, which is often a normal distribution, to select the rotation speed. However, other probability distributions can also be chosen. In this case, the difference in training speed and result between the normal distribution, a normal distribution to which a tangent hyperbolic function was applied, and the beta distribution was investigated. The beta distribution achieves the best results and can achieve the agent’s reward with the normal distribution after only 13 episodes, compared to 86 episodes. In addition, the beta distribution can increase the reduction of the average drag by 0.43 percentage points to 5.48% compared to the normal distribution. The agent using the tangent hyperbolic function was also able to achieve better results than the unmodified normal distribution, reducing the average drag by 0.1 percentage point to 5.15%. An agent with a beta distribution was then trained on 3 different but constant Reynolds numbers and applied to a time-varying flow. The maximum drag was reduced by 14.43 %. At times, the formation of the Kármán vortex street could even be completely prevented. Meanwhile, the average drag coefficient was reduced by 36.21 %.

description: We have performed first order reversal curve measurements of the temperature-driven metal-insulator transition in VO$_2$ thin films, which enable quantitative analysis of the hysteresis behavior. An unexpected tail-like feature in the contour plot of the reversal curve distribution indicates the existence of metallic domains, even at temperatures below the closing of the hysteresis. These domains interact with the surrounding medium and change the reversal path relative to a path from a \emph{fully} insulating state. With this in mind, and assuming that such interaction persist through the entire phase transition, we develop a model where the driving force (or energy barrier) in charge of opening a hysteresis in VO$_2$ are inter-domain interactions. This model is intrinsically different from the Preisach model usually used to describe hysteresis; given that it looks for the microscopic origin of the hysteresis, and provides physical parameters to characterize it.

description: "Since the conflict of the 1980s, New Caledonia is often presented as a haven of stability in the region, in comparison to neighbouring Melanesian countries like Papua New Guinea and Solomon Islands. But this paper will argue that there are cultural, political and social tensions in New Caledonia, and the issue of peace building and reconciliation is just as relevant today for the French dependency as for neighbouring independent countries." - page 1

description: There is a lack of robust epidemiological evidence on antipsychotic (AP) use in patients with agitation in Alzheimer’s disease (AD). Authors studied AP use in patients with AD and agitation and compared their use with patients with other or no neuropsychiatric symptoms (NPS). A retrospective cohort study in the UK Clinical Practice Research Datalink, included patients with AD between January 1st, 2015, and December 31st, 2017. AP use was compared between patients with agitation, other types of NPS and no NPS. There were 24,464 patients with AD, median follow-up of 1.1 years (interquartile range [IQR] 0.5–2.1), and median age 83 years (78–88). A larger percentage of patients with agitation (n = 2432) were prescribed APs (38.2%) than other NPS (n = 13,076, 20.4%) and no NPS (n = 11,816, 12.2%). Compared to patients with no NPS, adjusted hazard ratios for AP use were 3.45 (95% CI 2.86–4.17) for patients with agitation and 1.31 (95% CI 1.19–1.44) for patients with other NPS. Among users of APs, the treatment discontinuation rate at six months was 44.8% in patients with agitation (other NPS 57.1%; no NPS 63.5%). Patients with AD and agitation were frequently prescribed APs and for long periods in routine clinical practice in the UK. The high real-life usage of APs suggests that physicians prefer using APs for the treatment of agitation despite recommendations against their long-term use. These data support a need for AP therapies that better address known safety concerns with currently used APs to treat agitation in elderly patients with AD.

description: We examine the statistics of active scalar fluctuations in high-Rayleigh number fingering convection with high-resolution three-dimensional numerical experiments. The one-point distribution of buoyancy fluctuations is found to present significantly non-Gaussian tails. A modified theory based on an original approach by Yakhot (1989) is used to model the active scalar distributions as a function of the conditional expectation values of scalar dissipation and fluxes in the flow. Simple models for these two quantities highlight the role of blob-like coherent structures for scalar statistics in fingering convection.

description: We have implemented the standard ESONE CAMAC routines [1] as Hypercard XFCN's, using MPW 3.1 pascal[2]. This implementation (and this manual as well) are based on a set of CAMAC routines, also written in MPW PASCAL, by E. Wunsch at DESY[3]. The hardware requirements are a MAC-II with MICRON/MacVEE[4] interface ane one to eight MacCC-CAMAC-controllers[5]. In this hardware configuration all data transfers are restricted to 16 bit mode. The routines are available in a demo stack, HYPPOCAMPUS (HYPercard POwer for CAMac PUShbutton), which implements the software equivalent of the standard CAMAC Manual Controller. There is no support for LAMs yet. This work continues our attempt to use Hypercard as a powerful and simple human interface tool for data acquisition and control. See Ref.[6] for an equivalent set of routines for VME interface.

Investigations on plasmas produced in electromagnetic shock tubes.
Creators: name: Cormack, George Douglas
Publisher: name: University of British Columbia
Year: 2011

description: Electromagnetic shock tubes were used to generate plasmas having a number density of the order of 10¹⁷ per cm³ and an energy per particle of 1-3 ev. In the shock tubes employed, the driving current was passed via electrodes through a discharge at one end of the tube. The discharge gases that were driven down the shock tube plus the ambient gas that was picked up and heated constituted the plasma that was studied. Many workers have assumed that shock equations can describe the discontinuity at the front of the plasma. An investigation into the effects of changes in the geometry of the driver mechanism has disclosed that the luminosity structure that can be attributed to the discharge gases stays very close to the luminosity front. The amount of ambient gas that is entrained in front of the discharge gases is thus small. Therefore, some doubt exists about the applicability of the shock equations both in the present shock tube and in the electromagnetic shock tubes of other workers. The shape of the luminosity front of the plasma was found to be affected by the properties of the driving discharge, even at a time long after the driving current had ceased to flow. Instabilities of the discharge and contamination by electrode material were found to drastically affect the homogeneity of the plasma. The homogeneity and reproducibility of the plasma produced by a small-cathode driver were found to be fairly good. However, there was a large amount of contamination in the plasma. The plasma was used to investigate the electro-dynamic response of an inductive magnetohydrodynamic power generator. Expressions for the output power were derived and compared with the experimental results. The electrodynamical response of a novel electrode-type Bɵ magnetohydrodynamic power generator was calculated. In an experiment performed with this generator a magnetohydrodynamic Interaction was observed indicating that the plasma was transporting an azimuthal magnetic field. No output power was obtained. The probable cause for this was that the applied magnetic field was insufficient to break down the sheath on the electrodes. A low pressure spark gap switch suitable for use as a main switch and as a "crowbar" switch on a capacitor bank was developed. The switch was operated over a voltage range of 0.5 to 25 kV, at energies up to 4 kJ and currents up to 500 kA. Under normal operating conditions the triggering time was 40 nsec and the jitter approximately 10 nsec. The inductance of the main switch was 4 nH and the inductance of the crowbar switch was about 1 nH. Other contributions are presented on a wide-voltage-range open-air spark gap switch, high voltage trigger circuits and on the dynamics of the plasma in an electromagnetic shock tube. The latter consists of an elementary treatment of the electromagnetic acceleration processes and a proposal of a model for the decelerating plasma.

description: Acute kidney injury (AKI) is common among hospitalized patients with community-acquired pneumonia (CAP). We aimed to estimate and compare the risk of AKI for various antibiotic combinations in adults hospitalized for CAP. We conducted a retrospective cohort study of the Premier Healthcare Database containing all admissions for 660 US hospitals from 2010 to 2015. We included adults aged ≥18 years hospitalized with CAP and considered 6 different antibiotic combinations based on continuous use in the first 3 hospital days. The primary outcome was incident AKI, defined by ICD-9 codes 584.5-584-9. We evaluated associations of AKI with in-hospital mortality and length-of-stay. We excluded patients who were admitted directly to the intensive care unit, had AKI codes present on admission or had dialysis in the first 2 days. We used generalized linear mixed models with the hospital as a random effect and covariate adjustment for patient demographics, comorbidities, other treatments on day 0/1, and hospital characteristics. The total sample included 449,535 patients, 3.15% of whom developed AKI. All other regimens but fluoroquinolones exhibited higher AKI odds than 3rd generation cephalosporin with or without macrolide. The combination of piperacillin/tazobactam and vancomycin with or without other antibiotics was associated with the highest AKI odds (OR = 1.89; 95% CI: 1.73–2.06). Patients with incident AKI had an increased odds of hospital mortality (OR = 6.37; 95% CI: 6.07–6.69) and longer length-of-stay (mean multiplier = 1.84; 95% CI: 1.82, 1.86). Compared to 3rd generation cephalosporin with or without macrolide, piperacillin/tazobactam, vancomycin, and their combination were associated with higher odds of developing AKI, which in turn were associated with worse clinical outcomes.

description: A model for the parton distributions of hadrons in impact parameter space has been constructed using soft gluon summation. This model incorporates the salient features of distributions obtained from the intrinsic transverse momentum behaviour of hadrons. Under the assumption that the intrinsic behaviour is dominated by soft gluon emission stimulated by the scattering process, the b-spectrum becomes softer and softer as the scattering energy inreases. In minijet models for the inclusive cross-sections, this will counter the increase from sjet .

description: We have obtained mid-infrared optical absorption spectra of the S=1/2 quasi one-dimensional CuO using polarized transmission measurement and interpreted the spectra in terms of phonon assisted magnetic excitations. When the electric field is parallel to the main antiferromagnetic direction a Delta shaped peak is observed with the maximum at 0.23eV which is attributed to spinons along Cu-O chains. At low temperatures in the antiferromagnetic phase another peak appears at 0.16eV which is attributed to two-magnon absorption but the spinon peak remains. This behavior is interpreted as due to a dimensional crossover where the low temperature three-dimensional magnetic phase keeps short range characteristics of a one-dimensional magnet.

description: To measure health state preferences and estimate utility values for tardive dyskinesia (TD) from the perspective of the US general population, accounting for factors affecting quality of life (QOL). Participants from the general population were recruited and asked to watch and assess videos of professional actors simulating nine health states, including psychiatric disorders with/without TD and moderate-to-severe TD without any underlying disease. Time tradeoff (TTO) methods were used to elicit utility values, which ranged from −1 (worse than death) to +1 (perfect health) and represented individual preferences for avoiding specific health states associated with TD. Lower TTO utility values indicated individuals’ willingness to give up more years of life to avoid living in each health state. Based on TTO responses (n = 157), mean ± standard deviation utility for TD alone was 0.59 ± 0.38. Mean utilities for schizophrenia with negative symptoms (without TD: 0.43; with TD: 0.29) and positive symptoms (without TD: 0.44; with TD: 0.30) were generally lower than those for bipolar disorder (without TD: 0.59; with TD: 0.46) and major depressive disorder (without TD: 0.60; with TD: 0.44). According to utility decrements associated with TD (0.13–0.16), respondents were willing to give up 1.3 to 1.6 years during a 10-year lifespan to avoid living with TD. Utility decrements for TD in this study were slightly larger than previously reported values, potentially due to incorporation of QOL and social consequences in TD health state descriptions. An important limitation of this analysis is that participants’ willingness to trade future years of healthy life may not indicate actual willingness to accept the life decrement. These findings can be leveraged to improve cost-effectiveness analyses used to assess the value of treatments for TD.

D* Production from e+e- to ep Collisions in NLO QCD

Year: 1997

description: Fragmentation finctions for D mesons, based on the convolution of a perturbative part, related to the heavy quark perturbative showering, and a non-perturbative model for its hadronization into the meson, are used to describe D* production in e+e- and ep collisions. The non-perturbative part is determined by fitting the e+e- data taken by ARGUS and OPAL at 10.6 and 91.2 GeV respectively. When fitting with a non perturbative Peterson fragmentation function and using next-to-leading evolution for the perturbative part, we find an  parameter significantly different from the one commonly used, wich is instead found with a leading order fit. The use of this new value is shown to increase considerably the cross section  D* production at HERA, suggesting a possible reconciliation between the next-to-leading order theoretical predictions and the experimental data.

description: The properties of the two-flavored Gross-Neveu model in the (1+1)-dimensional spacetime are investigated in the presence of the isospin $μ_I$ as well as quark number $μ$ chemical potentials both at zero and nonzero temperatures. The consideration is performed in the limit $N_c\to\infty$, i.e. in the case with an infinite number of colored quarks. In the plane of parameters $μ_I,μ$ a rather rich phase structure is found, which contains phases with and without pion condensation. Moreover, we have found a great variety of one-quark excitations of these phases, including gapless and gapped quasiparticles.

description: (Abridged) We study numerically the applicability of the effective-viscosity approach for simulating the effect of gravitational instability (GI) in disks of young stellar objects with different disk-to-star mass ratios ξ. We adopt two α$-parameterizations for the effective viscosity based on Lin & Pringle (1990) and Kratter et al (2008) and compare the resultant disk structure, disk and stellar masses, and mass accretion rates with those obtained directly from numerical simulations of self-gravitating disks around low-mass (M_\ast ~ 1.0 M_sun) protostars. We find that the effective viscosity can, in principle, simulate the effect of GI in stellar systems with ξ<= 0.2-0.3, thus corroborating a similar conclusion by Lodato & Rice (2004) that was based on a different α-parameterization. In particular, the Kratter et al's α-parameterization has proven superior to that of Lin & Pringle's, because the success of the latter depends crucially on the proper choice of the α-parameter. However, the α-parameterization generally fails in stellar systems with ξ>= 0.3, particularly in the Class 0 and Class I phases of stellar evolution, yielding too small stellar masses and too large disk-to-star mass ratios. The failure of the α-parameterization in the case of large ξis caused by a growing strength of low-order spiral modes in massive disks.

description: We report on the discovery and initial observations of the energetic type IIn supernova (SN), 2008fz. The optical energy emitted by SN 2008fz (based on the light curve over a 88 day period), is possibly the most ever observed for a supernova (1.4 x 10^51 erg). The event was more luminous than the type IIn SN 2006gy, but exhibited same smooth, slowly evolving light curve. As is characteristic of type IIn SN, the early spectra of 2008fz initially exhibited narrow Balmer lines which were replaced by a broader component at later times. The spectra also show a blue continuum with no signs of Ca or Na absorption, suggesting that there is little extinction due to intragalatic dust in the host or circumstellar material. No host galaxy is identified in prior coadded images reaching R ~ 22. From the supernova's redshift, z=0.133, we place an upper limit on the host of M_R=-17. The presence of the SN within such a faint host follows the majority of recently discovered highly luminous SN. A possible reason for this occurrence is the very high star formation rate occurring in low-mass galaxies in combination with the low metallicity environment, which makes the production of very massive stars possible. We determine the peak absolute magnitude of the event to be M_V = -22.3 from the initial photometry and the redshift distance, placing it among the most luminous supernovae discovered.

description: Several tests has been performed trying to over-load (D/Pd> 0.8) a Pd wire with Deuterium by mean of electrolytic procedures. A proper elicoidal electrodes geometry has been adopted to provide opportune electric fields during the electrolysis and several picks up has been located along the wires to obtain a profile of wire Deuterium concentration by mean the resistivity.Tests operated with high electric current (up to 1 A) flowing along the wire and low electrolytic voltage showed a D/Pd loading of 0.75 at maximum. Tests operated with high voltage (from 50 to 100 V) have showed in some cases an overcoming of D/Pd= 0.95. In these cases an anomalous effect of cyclical loading/deloading has been newly observed by this group. No average anomalous heat in excess (more than 15%) has been observed during these tests.

The CP-Conserving Contribution to the Transverse muon Polarization in K^+→μ^+ υγ
Creators: name: G. Hiller

Publisher: name: INFN Open Access Repository
Year: 1999

description: We present a detailed estimate of the transverse muon polarization (P_T) due to electromagnetic final-state interactions in the decay K^+→μ^+ υγ. This CP-conserving effect represents the dominant contribution to P_T within the Standard Model. As a result of an explicit calculation, we find that the CP-conserving contribution to P_T is quite small, typically of O(10^{-4}), essentially due to the suppression factor α/4π^2. This enforces the sensitivity of P_T in probing extensions of the Standard Model with new sources of time-reversal violations. A brief discussion about possible CP-violating contributions to P_Tin the framework of supersymmetric models with unbroken R-parity is also presented.

description: Nuclear magnetic resonance studies in single crystals of aluminum and tin have been done at liquid helium temperatures. The Knight shift in tin has been studied as a function of crystal orientation in a constant magnetic field for different values of field and temperature. The anisotropic Knight shift in tin was observed directly for the first time. The line width of the tin resonance was also studied and found to depend on the crystal orientation in the magnetic field. The second moment of the line has been calculated in terms of dipole-dipole interactions and indirect exchange interactions between nuclei of different magnetic moments and compared with the experimental results. The Knight shift was studied as a function of external field for both tin and aluminum in a search for de Haas-van Alphen type oscillations. No indication of these was found. An upper limit for this effect was determined for each sample.

description: The objective of this survey was to assess patient outcomes and caregiver status by disease severity among patients with schizophrenia in the United States. A point-in-time survey was conducted between July and October 2019 via the Adelphi Schizophrenia Disease Specific Programme. Psychiatrists reported on their next 10 eligible patients with schizophrenia including demographics, disease severity, treatment history and hospitalizations. Patients receiving treatment for schizophrenia were classified as mild, moderate or severe based on disease severity. Regression models adjusted for age, sex and race/ethnicity. Psychiatrists (n = 124) reported on 435 mild, 401 moderate and 247 severe patients. Greater severity of schizophrenia was associated with a greater number of hospitalizations related to schizophrenia relapse in the previous 12 months (moderate vs. mild: adjusted incidence rate ratio (aIRR) [95% CI] = 2.17 [1.60–2.94]; severe vs. mild: aIRR = 5.45 [3.59–8.27]), lower full-time employment (moderate vs. mild: adjusted odds ratio (aOR) = 0.15 [0.08–0.28]; severe vs. mild: aOR = 0.02 [0.002–0.12]) and greater unemployment due to disability (moderate vs. mild: aOR = 4.24 [3.02–5.97]; severe vs. mild: aOR = 10.85 [6.85–17.17]). Patients with severe vs. mild schizophrenia had lower average quality of life (QoL) measured by the EuroQoL 5-dimension Health Index (difference = −0.16 [−0.23−0.09]). Among patients requiring care, patients with severe vs. mild schizophrenia received more caregiver hours per week (aIRR = 1.89 [1.25–2.84]). Greater severity of schizophrenia was associated with a significantly greater number of hospitalizations and greater unemployment due to disability. Compared with mild schizophrenia, severe schizophrenia was associated with worse patient QoL and greater caregiver hours.
