Methods: We prospectively recruited asymptomatic patients with no history or symptoms of hip pathology who underwent abdomen-pelvis computed tomography (CT) for a nonorthopaedic indication. The acetabular and femoral parameters related to FAI were measured. Results: We studied 101 subjects (202 hips) with a mean age of 36.8 ± 14.4 years. The mean center-edge angle was 39.4 ± 7.2 . The crossover...

Monoclonal antibodies specific to the alpha subunits of the photosynthetic coupling factor 1 (CF(1)) were used as marker molecules in an electron microscopic analysis of the subunit organization of this enzyme. Immune complexes were obtained by incubation of CF(1) with saturating amounts of anti-alpha-subunit IgG, isolated by gel filtration, and visualized by electron microscopy. The maximum nu...

A method is described for sequential resonance assignment of protein 1H-NMR spectra relying on the detection of long-range correlations between 15N and C alpha H atoms using 1H-detected heteronuclear multiple-bond correlation spectroscopy. In particular, the observation of the two-bond 15N(i)-C alpha H(i) and three-bond 15N(i)-C alpha H(i-1) correlations enables one to connect one residue with ...

We have studied the ground state of a fullerene-based magnet, the alpha;{'}-phase tetra-kis-(dimethylamino)-ethylene-C60 (alpha'-TDAE-C(60)), by electron spin resonance and magnetic torque measurements. Below T(N) = 7 K, nonparamagnetic field dependent resonances with a finite excitation gap (1.7 GHz) are observed along the a axis. Strong enhancement in their intensity as temperature is decreas...

Complexes of double-stranded DNA with the cationic surfactant cetyltrimethylammonium bromide have been studied using small angle x-ray diffraction at varying concentrations of DNA and the cosurfactant hexanol. At low DNA concentrations, an intercalated hexagonal (H(c)(I))-->lamellar (L(c)(alpha))-->inverted hexagonal (H(c)(II)) transformation is found on increasing hexanol content. The H(c)(II)...

The optical appearance of etched alpha-particle tracks in CR-39 SSNTDs under the transmission mode of the optical microscope were studied. The mean grey levels revealed using a digital camera installed on the microscope, together with the major and minor axes were systematically determined for tracks from alpha particles with different incident energies and angles. The grey level properties for...

The nucleon energy-energy correlator (NEEC) was proposed recently [X. Liu and H. X. Zhu, Phys. Rev. Lett. 130, 091901 (2023)] as a new way of studying intrinsic dynamics. In this work, we present detailed derivation the factorization theorem that enables measurement unpolarized NEEC in lepton-nucleon collisions. As first step toward precise quantity, obtained next-to-leading-logarithmic [NLL, $...

Two-dimensional (2D) Dirac states with linear band dispersion have attracted enormous interest since the discovery of graphene. However, to date, 2D semimetals are still very rare due fact that generally fragile against perturbations such as spin-orbit couplings. Nonsymmorphic crystal symmetries can enforce formation nodes, providing a new route establishing symmetry-protected in materials. Her...

The Alpha Magnetic Spectrometer (AMS) to be installed on the International Space Station (ISS) will be equipped with a proximity focusing Ring Imaging Čerenkov detector (RICH). Reconstruction of the Čerenkov angle and the electric charge with RICH are discussed. A likelihood method for the Čerenkov angle reconstruction was applied leading to a velocity determination for protons with a resolutio...

We investigate the stability of a granular monolayer composed of spherical grains on an inclined plate. When the tilt angle alpha increases, some reorganizations are observed throughout the pile. The packing fraction rho of the packing evolves by successive jumps. Those discontinuous events precede the collapse of the pile at a critical angle alphac. The occurrence of precursors before avalanch...
