Study of Ultrasonic Guided Wave Propagation in Bone Composite Structures for Revealing Osteoporosis Diagnostic Indicators.

Tubular bones are layered waveguide structures composed of soft tissue, cortical and porous bone tissue, and bone marrow. Ultrasound diagnostics of such biocomposites are based on the guided wave excitation and registration by piezoelectric transducers applied to the waveguide surface. Meanwhile, the upper sublayers shield the diseased interior, creating difficulties in extracting information about its weakening from the surface signals.

Occurrences of Threatened Species included in the Third Edition of the Red Data Book of the Komi Republic (Russia).

Background: The purpose of the data paper was to introduce into scientific literature the results of scientific work carried out for the third edition of the 'Red Data Book of the Komi Republic'. The article reflects methodological approaches to the formation of a list of rare and in need of protection species and describes the corresponding datasets published in GBIF.

New Information: Information about 7,187 occurrences of 438 rare species and infraspecies included in the third edition of the 'Red Data Book of the Komi Republic' have been published.

The effect of galanin gene polymorphism rs948854 on the severity of multiple sclerosis: A significant association with the age of onset.

Background: Data on genetic markers that determine the prognosis of multiple sclerosis (MS) is still limited. The association between galanin gene polymorphism rs948854 and prognosis of MS had been demonstrated earlier.

Objectives: To confirm earlier findings in a distinct from the previously studied cohort of patients, and to further characterized the rs948854 polymorphism as one of the candidates for the risk stratification in patients with MS.

Azimuthal separation in nearly back-to-back jet topologies in inclusive 2- and 3-jet events in collisions at .

A measurement for inclusive 2- and 3-jet events of the azimuthal correlation between the two jets with the largest transverse momenta, , is presented. The measurement considers events where the two leading jets are nearly collinear ("back-to-back") in the transverse plane and is performed for several ranges of the leading jet transverse momentum. Proton-proton collision data collected with the CMS experiment at a center-of-mass energy of and corresponding to an integrated luminosity of are used.

Measurement of exclusive photoproduction in ultraperipheral pPb collisions at .

Exclusive photoproduction is measured for the first time in ultraperipheral pPb collisions at with the CMS detector. The cross section is b at for photon-proton centre-of-mass energies between 29 and . The differential cross section is measured in the interval as a function of , where is the squared four-momentum transfer at the proton vertex.
