Tactile perception of the roughness of 3D-printed textures.

Surface roughness is one of the most important qualities in haptic perception. Roughness is a major identifier for judgments of material composition, comfort, and friction and is tied closely to manual dexterity. Some attention has been given to the study of roughness perception in the past, but it has typically focused on noncontrollable natural materials or on a narrow range of artificial materials.

Assessing T cell clonal size distribution: a non-parametric approach.

Clonal structure of the human peripheral T-cell repertoire is shaped by a number of homeostatic mechanisms, including antigen presentation, cytokine and cell regulation. Its accurate tuning leads to a remarkable ability to combat pathogens in all their variety, while systemic failures may lead to severe consequences like autoimmune diseases. Here we develop and make use of a non-parametric statistical approach to assess T cell clonal size distributions from recent next generation sequencing data.

Real-time creased approximate subdivision surfaces with displacements.

We present an extension of Loop and Schaefer's approximation of Catmull-Clark surfaces (ACC) for surfaces with creases and corners. We discuss the integration of ACC into Valve's Source game engine and analyze performance of our implementation.

[Transurethral electrosurgery of a new generation (TURis) in the treatment of the lower urinary tract and prostate diseases].

Surgical interventions were made in 175 patients aged 23-87 years (mean age 64.8 years) with different diseases of the lower urinary tract (adenoma, prostatic cancer, cancer of the urinary bladder, etc.) with application of a new generation of endoscopic technique--transurethral resection in saline (TURis system) with a generator UES-40 SurgMaster (Olympus).
