A comparison between the observed spectrum of 155Dy and calculations suggests that the yrast states in the I+30-40 region are built from bands whose deformation smoothly changes towards oblate shape (γ=60°) with band terminations in the I=45-50 region. The presence of other bands which show no terminating features is also naturally understood within the same theoretical framework.
We report low-temperature magnetotransport studies of individual InAs nanowires grown by molecule beam epitaxy. At low magnetic fields, the magnetoconductance characteristics exhibit a crossover between weak antilocalization and weak localization by changing either the gate voltage or the temperature. The observed crossover behavior can be well described in terms of relative scales of the transpor
A paired cranked Nilsson-Strutinsky-Bogoliubov (CNSB) model is presented, which employs the same method to calculate the liquid-drop energy and moment of inertia as the unpaired cranked Nilsson-Strutinsky (CNS) model. In the CNSB model, the energy minimization is carried out in the mesh of pairing gaps Delta and Fermi levels lambda as well as deformation parameters. The high spin states in Lu-161
NMR spin relaxation in the rotating frame (R-1 rho) is a unique method for atomic-resolution characterization of conformational ( chemical) exchange processes occurring on the microsecond time scale. Here, we use amide H-1 off-resonance R-1 rho relaxation experiments to determine exchange parameters for processes that are significantly faster than those that can be probed using N-15 or C-13 relaxa
X-ray absorption spectroscopy is a powerful probe of molecular structure, but it has previously been too slow to track the earliest dynamics after photoexcitation. We investigated the ultrafast formation of the lowest quintet state of aqueous iron(II) tris(bipyridine) upon excitation of the singlet metal-to-ligand-charge-transfer ( 1
PURPOSE: To propose and assess an improved method for calculating the equilibrium magnetization of arterial blood ( M0a), used for calibration of perfusion estimates in arterial spin labeling.METHODS: Whereas standard M0a calculation is based on dividing a proton density-weighted image by an average brain-blood partition coefficient, the proposed method exploits partial-volume data to adjust this
We have used femtosecond resolution UV-visible and Kβ x-ray emission spectroscopy to characterize the electronic excited state dynamics of [Fe(bpy)2(CN)2], where bpy=2,20-bipyridine, initiated by metal-to-ligand charge transfer (MLCT) excitation. The excited-state absorption in the transient UV-visible spectra, associated with the 2,20-bipyridine radical anion, provides a robust marker for the MLC
Most of the decisive molecular events in biology take place at the protein-water interface. The dynamical properties of the hydration layer are therefore of fundamental importance. To characterize the dynamical heterogeneity and rotational activation energy in the hydration layer, we measured the 17O spin relaxation rate in dilute solutions of three proteins in a wide temperature range extending d
Quark spin effects in e+e- annihilation to pseudoscalar and vector mesons are implemented for the first time in the pythia Monte Carlo event generator. The spin-dependent fragmentation of the string stretched between the produced quark-antiquark pair with correlated spin states is described by the string+P30 model implemented in the string fragmentation routine of pythia by using the StringSpinner
Richter Group Our ResearchOsteoclasts and osteoblasts are two important mediators in the tightly regulated process of bone remodelling. The bone-forming osteoblasts are of mesenchymal origin while the multinucleate osteoclasts, which are responsible for bone resorption, are derived from hematopoietic stem cells (HSCs). An imbalance between the production and destruction of bone can lead to either

The position generator is a widespread method for measuring latent social capital in which respondents are queried about contacts on a list of occupations predefined by the analyst. We separate out the unique contribution of each occupation to aggregated measures of social capital. It turns out that this contribution varies vastly: knowing a person in some occupations provides substance to measure
BackgroundA concussion is a common injury in many sports, including para sport. Aside from a more comprehensive need for concussion education, clinicians face difficulties applying concussion assessment and management guidelines to para athletes.1 At present, there is a lack of para-sport concussion research, and prior International Concussion in Sport (CIS) consensus papers have not addressed thi
Swedish society is characterized by secularization, and at the same time, as a result of migration, the country has become more pluralistic. An important consequence of this is the increasing possibilities for cooperation between different religious communities, and a variety of inter-religious cooperation are currently taking place in Sweden. The aim of the article is to show how inter-religious
With near stagnant growth in most mature car markets, much of the attention of the world´s car industry has during recent years turned to China. The Chinese car market represents an important business opportunity for OEMs and dealers who want to keep growing and making profits. Initially, the focus of OEMs was mainly on setting up new dealerships, often giving processes and technology lower priori
The semiconductor industry is pivotal to Europe's economy, especially within the industrial and automotive sectors. However, Europe faces a significant shortfall in chip design capabilities, marked by a severe skilled labor shortage and lagging contributions in the design value chain segment. This paper explores the role of European universities and academic initiatives in enhancing chip design ed
The magnitude of variation in the gaze position signals recorded by an eye tracker, also known as its precision, is an important aspect of an eye tracker’s data quality. However, data quality of eye-tracking signals is still poorly understood. In this paper, we therefore investigate the following: (1) How do the various available measures characterizing eye-tracking data during fixation relate to
