Gold catalysis has become one of the fastest growing fields in chemistry, providing new organic transformations and offering excellent chemoselectivities under mild reaction conditions. Methodological developments have been driven by wide applicability in the synthesis of complex structures, whereas the mechanistic understanding of Au(III)-mediated processes remains scanty and have become the Achilles' heel of methodology development. Herein, the systematic investigation of the reactivity of bis( ...

Clonidine and morphine depress nociceptive reflex responses when given alone; when given in combination, the effect of each is potentiated by the other. The present study was designed to test if activity in ascending axons evoked by electrical stimulation of afferent C-fibers in the sural nerve of the rat also exhibits potentiation of the depressant effects of clonidine and morphine when both drugs are administered in combination by intrathecal (i.t.) injection to the lumbar spinal cord. For comparison, ...

Making predictions with an associated confidence is highly desirable as it facilitates decision making and resource prioritization. Conformal regression is a machine learning framework that allows the user to define the required confidence and delivers predictions that are guaranteed to be correct to the selected extent. In this study, we apply conformal regression to model molecular properties and bioactivity values and investigate different ways to scale the resultant prediction intervals to create ...

In central theories of monetary non-neutrality, the Ramsey optimal steady-state inflation rate varies between the negative of the real interest rate and zero. This paper explores how the interaction of nominal wage and search and matching frictions affect the policy prescription. We show that adding the combination of such frictions to the canonical monetary model can generate an optimal inflation rate that is significantly positive. Specifically, for a standard U.S. calibration, we find a Ramsey ...

The isolated silicon vacancy is one of the basic intrinsic defects in SiC. We present new experimental data as well as new calculations on the silicon vacancy defect levels and a new model that explains the optical transitions and the magnetic resonance signals observed as occurring in the singly negative charge state of the silicon vacancy in 4H and 6H SiC.

A model is presented for the silicon vacancy in SiC. The previously reported photoluminescence spectra in 4H and 6H SiC attributed to the silicon vacancy are in this model due to internal transitions in the negative charge state of the silicon vacancy. The magnetic resonance signals observed are due to the initial and final states of these transitions.

Abstract 200 µm thick 4H‐SiC epilayers have been grown by chloride‐based chemical‐vapor deposition using methyltrichlorosilane (MTS) as single precursor. The very high crystalline quality of the grown epilayer is demonstrated by high resolution X‐Ray Diffraction rocking curve with a full‐width‐half‐maximum value of only 9 arcsec. The high quality of the epilayer is further shown by low temperature photoluminescence showing strong free exciton and nitrogen bound exciton lines. The very high crystalline ...

Progresses in defects characterization of high-purity semi-insulating (HPSI) SiC substrates are reviewed. The vacancies, divacancy, and carbon vacancy–carbon antisite pairs were found to be dominating defects in HPSI 4H-SiC substrates with the thermal activation energy Ea in the range ∼0.6–1.6 eV. Several vacancy-related deep acceptor levels were estimated and suggested to be responsible for the semi-insulating (SI) behavior in substrates with different Ea. Deep levels associated with different activation ...

Laparoscopic radical prostatectomy has shown excellent results concerning patient morbidity, with less blood loss compared to conventional surgery. Robot-assisted laparoscopy offers several additional important technical improvements and therefore it might be suggested that robotic radical prostatectomy would also offer surgical advantages. The objective of this study was to evaluate urinary continence for the first 72 cases of robot-assisted radical prostatectomy performed by a single surgical ...

In this paper, we outline a baseline DSGE model which enables a straightforward analysis of wage bargaining between firms and households/unions in a model with both staggered prices and wages. Relying on empirical evidence, we assume that prices can be changed whenever wages are changed. This feature of the model greatly reduces the complexity of the price and wage setting decisions; specifically it removes complicated interdependencies between current and future price and wage decisions. In an ...

The lithium abundances in metal-poor halo stars are of importance for cosmology, galaxy evolution and stellar structure. In an attempt to study possible systematic errors in the derived Li abundances, the line formation of LiI lines has been investigated by means of realistic 3D hydrodynamical model atmospheres of halo stars and 3D non-LTE radiative transfer calculations. These are the first detailed 3D non-LTE computations reported employing a multi-level atomic model showing that such problems ...

The synthesis of the ubiquitous tripeptide glutathione is impaired in patients with glutathione synthetase deficiency. The defect is inherited in an autosomal recessive manner, and the diagnosis is based on clinical, biochemical, and genetic criteria. In seven of our 30 index cases, however, no disease causing mutations could be identified in the coding exons or exon-intron boundaries of the glutathione synthetase gene GSS. These patients had severely decreased glutathione synthetase activities ...

Heparin-induced thrombocytopenia (HIT) is an immune-mediated adverse drug reaction associated with a decrease of platelet counts that usually begins after at least 5 days of heparin treatment. Uncertainty exists about the risk of early onset of HIT (ie, < 5 days) in relation to previous heparin exposure. We therefore analyzed the temporal pattern of thrombocytopenia in patients with laboratory-confirmed HIT to assess whether patients with previous heparin exposure have an increased risk of early onset ...
