Search for π0 decays to invisible particles

The NA62 experiment at the CERN SPS reports a study of a sample of 4 × 109 tagged π0 mesons from K+ → π+π0(γ), searching for the decay of the π0 to invisible particles. No signal is observed in excess of the expected background fluctuations. An upper limit of 4.4 × 10−9 is set on the branching ratio at 90% confidence level, improving on previous results by a factor of 60. This result can also be i

Implementation of the Recovery Guide in inpatient mental health services in Sweden-A process evaluation study

Background: Involving service users in inpatient care and recovery planning has gained interest worldwide. Our purpose was to evaluate the process of implementation of a coproduced Recovery Guide (RG) intervention in 22 inpatient wards in Sweden, in terms of context, implementation process and mechanisms of impact over 12 months.Methods: A mixed method design and a process evaluation framework wer

Monte Carlo simulations of the GE discovery alcyone CZT SPECT system

Compact SPECT systems with cadmium zinc telluride (CZT) solid-state detectors with improved energy resolution and shorter acquisition times have recently been introduced. These systems have, however, different energy characteristics compared to NaI(Tl) crystal-based cameras. There is therefore a need to develop new simulation models for these cameras. We modeled the charge transport within the CZT

Disentangling transient charge order from structural dynamics contributions during coherent atomic motion studied by ultrafast resonant x-ray diffraction

We report on the ultrafast dynamics of charge order and structural response during the photoinduced suppression of charge and orbital order in a mixed-valence manganite. Employing femtosecond time-resolved resonant x-ray diffraction below and at the Mn K absorption edge, we present a method to disentangle the transient charge order and structural dynamics in thin films of Pr0.5Ca0.5MnO3. Based on

Production of K∗(892)0 and ϕ (1020) in p–Pb collisions at √sNN = 5.02 TeV

The production of K∗(892)0 and ϕ(1020) mesons has been measured in p–Pb collisions at sNN= 5.02 TeV. K∗ 0 and ϕ are reconstructed via their decay into charged hadrons with the ALICE detector in the rapidity range - 0.5 < y< 0. The transverse momentum spectra, measured as a function of the multiplicity, have a pT range from 0 to 15 GeV/c for K∗ 0 and from 0.3 to 21 GeV/c for ϕ. Integrated yields, m

Monocular Estimation of Translation, Pose and 3D Shape on Detected Objects using a Convolutional Autoencoder

This paper present a 6DoF-positioning method and shape estimation method for cars from monocular images.We pre-learn principal components, using Principal Component Analysis (PCA), from the shape of cars anduse a learnt encoder-decoder structure in order to position the cars and create binary masks of each camera instance. The proposed method is tailored towards usefulness for autonomous driving a

Iterative cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy for colorectal peritoneal metastases : A multi-institutional experience

BACKGROUND AND OBJECTIVES: The aims of this multi-institutional study were to assess the feasibility of iterative cytoreductive surgery (iCRS)/hyperthermic intraperitoneal chemotherapy, iCRS in colorectal peritoneal carcinomatosis (CRPC), evaluate survival, recurrence, morbidity and mortality outcomes, and identify prognostic factors for overall survival.METHODS: Patients with CRPC that underwent

Politics Makes for Strange Bedfellows : Exigency and Sectarian Politics in Lebanon

The alliance between the seemingly disparate Lebanese Christian party Free Patriotic Movement and the Shi’a organization Hezbollah has survived many local and regional upheavals since the signing of the memorandum of understanding (MoU) in February 2006. The pact was strengthened after the 2006 summer war and has stood for 15 years - despite political assassinations and low-intensity conflict in L

Production cross section and decay study of Es 243 and Md 249

In the study of the odd-Z, even-N nuclei Es243 and Md249, performed at the University of Jyväskylä, the fusion-evaporation reactions Au197(Ca48,2n)Es243 and Tl203(Ca48,2n)Md249 have been used for the first time. Fusion-evaporation residues were selected and detected using a gas-filled separator coupled with its focal-plane spectrometer. For Es243, the recoil decay correlation analysis yielded a ha

Cubic anisotropy in (Ga,Mn)As layers : Experiment and theory

Historically, comprehensive studies of dilute ferromagnetic semiconductors, e.g., p-type (Cd,Mn)Te and (Ga,Mn)As, paved the way for a quantitative theoretical description of effects associated with spin-orbit interactions in solids, such as crystalline magnetic anisotropy. In particular, the theory was successful in explaining uniaxial magnetic anisotropies associated with biaxial strain and nonra

Search for heavy diboson resonances in semileptonic final states in pp collisions at √s=13 TeV with the ATLAS detector

This paper reports on a search for heavy resonances decaying into WW, ZZ or WZ using proton–proton collision data at a centre-of-mass energy of s=13 TeV. The data, corresponding to an integrated luminosity of 139 fb 1, were recorded with the ATLAS detector from 2015 to 2018 at the Large Hadron Collider. The search is performed for final states in which one W or Z boson decays leptonically, and the

Breaking into language in a new modality : the role of input and of individual differences in recognising signs

A key challenge when learning language in naturalistic circumstances is to extract linguistic information from a continuous stream of speech. This study investigates the predictors of such implicit learning amongst adults exposed to a new language in a new modality (a sign language). Sign-naïve participants (N=93; British-English speakers) were shown a 4-minute weather forecast in Swedish Sign

Surface guided radiation therapy: : An international survey on current clinical practice

Introduction: Surface Guided Radiation Therapy (SGRT) is being increasingly implemented into clinical practiceacross a number of techniques and irradiation-sites. This technology, which is provided by different vendors, canbe used with most simulation- and delivery-systems. However, limited guidelines and the complexity of clinicalsettings have led to diverse patterns of operation. With the aim to

Micellar crowding and branching in a versatile catanionic system

The catanionic system didodecyldimethylammonium bromide (DDAB)-sodium taurodeoxycholate (STDC)-D2O is characterized by an exceptionally extended L1 region. The comparison of self-diffusion coefficient of the solvent and the DDAB embedded in the micelles provided information about hydration of the aggregates. Moreover, correlating self-diffusion and 14N NMR relaxation measurements new insight could
