Nuclear surface dynamics and pairing correlations

We solve the Nambu-Gor'kov equations in 120Sn, demonstrating that the coupling of quasiparticles with collective surface vibrations renormalizes the low-lying part of the nuclear spectrum and influences pairing correlations in a substantial way.

Dynamical processes in the structure of halo nuclei and their experimental evidence

High polarizability and halo phenomena are strongly correlated, as evidenced by the qualitative changes of the nuclear spectrum which arise taking into account the dynamical coupling of the valence neutrons with the collective vibrations of the system. Direct experimental evidence of their role in the induced pairing interaction binding the halo neutrons of 11Li to the core 9Li is provided by the

Contribution of Nuclear Field Theory medium effects to the pairing gap

We calculate the different contributions to the pairing gap for the case of the superfluid nucleus 120Sn, making use of the Dyson equation (also known as the Nambu-Gor'kov equation in the case of superfluid systems) to propagate leading medium polarization Nuclear Field Theory (NFT) processes to all orders. Starting from a mean field obtained with the SLy4 effective force (mk ≈ 0.7), we renormaliz

Dose painting based on tumor uptake of Cu-ATSM and FDG : a comparative study

BACKGROUND: Hypoxia and increased glycolytic activity of tumors are associated with poor prognosis. The purpose of this study was to investigate differences in radiotherapy (RT) dose painting based on the uptake of 2-deoxy-2-[(18) F]-fluorodeoxyglucose (FDG) and the proposed hypoxia tracer, copper(II)diacetyl-bis(N(4))-methylsemithiocarbazone (Cu-ATSM) using spontaneous clinical canine tumor model

Patterns of failure for patients with glioblastoma following O-(2-[18F]fluoroethyl)-L-tyrosine PET- and MRI-guided radiotherapy

Background and purpose To evaluate the patterns of failure following clinical introduction of amino-acid O-(2-[18F]fluoroethyl)-L-tyrosine (FET)-PET-guided target definition for radiotherapy (RT) of glioblastoma patients. Materials and methods The first 66 consecutive patients with confirmed histology, scanned using FET-PET/CT and MRI were selected for evaluation. Chemo-radiotherapy was delivered

Robustness of the Voluntary Breath-Hold Approach for the Treatment of Peripheral Lung Tumors Using Hypofractionated Pencil Beam Scanning Proton Therapy

Purpose The safe clinical implementation of pencil beam scanning (PBS) proton therapy for lung tumors is complicated by the delivery uncertainties caused by breathing motion. The purpose of this feasibility study was to investigate whether a voluntary breath-hold technique could limit the delivery uncertainties resulting from interfractional motion. Methods and Materials Data from 15 patients with

The association of partial pressures of oxygen and carbon dioxide with neurological outcome after out-of-hospital cardiac arrest : an explorative International Cardiac Arrest Registry 2.0 study

BACKGROUND: Exposure to extreme arterial partial pressures of oxygen (PaO2) and carbon dioxide (PaCO2) following the return of spontaneous circulation (ROSC) after out-of-hospital cardiac arrest (OHCA) is common and may affect neurological outcome but results of previous studies are conflicting.METHODS: Exploratory study of the International Cardiac Arrest Registry (INTCAR) 2.0 database, including

Association between pelvic obliquity and scoliosis, hip displacement and asymmetric hip abduction in children with cerebral palsy : a cross-sectional registry study

BACKGROUND: Pelvic obliquity (PO) is common in individuals with cerebral palsy (CP). The prevalence of PO in a population of children with CP and its associations with scoliosis, hip displacement and asymmetric range of hip abduction were analysed. METHODS: Over a 5-year period all pelvic radiographs from the Swedish surveillance programme for CP and the recorded data for scoliosis and hip abducti

Frequency synchronization of a high-order multi-converter system

We investigate the stability properties of a multi-converter power system model, defined on a high-order manifold. For this, we identify its symmetry (i.e., rotational invariance) generated by a static angle shift and rotation of AC signals. We characterize the steady state set, primarily determined by the steady state angles and DC power input. Based on eigenvalue conditions of its Jacobian matri

Incidence and Associated Risk Factors of Venous Thromboembolism After Open and Laparoscopic Nephrectomy in Patients Administered Short-period Thromboprophylaxis : A Danish Nationwide Population-based Cohort Study

Objective: To report the incidence of venous thromboembolism (VTE) after nephrectomy in Denmark and explore associated risk factors. Materials and Methods: A nationwide population-based retrospective cohort study was performed. All nephrectomies from January 2010 to August 2018 were assessed for postoperative VTE events. Univariable and multivariable analyses were used to evaluate the odds ratio (

Confirmation of sex pheromone biosynthesis from (16-D3)palmitic acid in the turnip moth using capillary gas chromatography

(16-D3)palmitic acid was applied topically to pheromone glands of the turnip moth. After incubation omega labeled analogues of fatty acid methyl esters and acetates were identified by gas chromatography with flame ionization detection and selected ion monitoring. The pheromone components (Z)-5-decenyl, (Z)-7-dodecenyl- and (Z)-9-tetradecenyl acetate were all biosynthesized from palmitic acid along

Affordance-based evaluation of signage design for areas of refuge

The evacuation of disabled persons from multi-storey buildings requires, typically, the provision and use o Areas of Refuge (AoR). Building complexity, together with the low level of detail in the regulatory guidance- relating to AoR signage, may lead to inappropriate signage system designs. In turn. this may lead to difficulties in locating and or identifying AoR. This paper illustrates the use o

Continuous single sensillum recording as a detection method for moth pheromone components in the effluent of a gas chromatograph

ABSTRACT. Single sensillum recordings were made from male antennal pheromone receptors of Agrotis segetum (Schiff.) (Noctuidae) and Adoxophyes orana (F.v.R.) (Tortricidae). A gas chromatograph (GC) was used to prepare and to deliver the odour stimuli. Samples of female abdominal gland extracts were injected into the column of the GC and the responses of the receptor cells to the effluent were reco

Core polarization and neutron halos

The effects of core polarization on the structure of Li and Be halos and their consequences on one-and two-neutron transfer reactions are discussed.

Premature Termination of a Randomized Controlled Trial on Image-Guided Stereotactic Body Radiotherapy of Metastatic Spinal Cord Compression

Lessons Learned: It is possible to plan and treat some patients with stereotactic body radiotherapy (SBRT) in a timely fashion in an acute setting. Advanced and, in some indications, already implemented technologies such as SBRT are difficult to test in a randomized trial. Background: Stereotactic body radiotherapy (SBRT) in metastatic spinal cord compression (MSCC) could be an alternative to deco
