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).

[Recruiting maneuver used in the treatment of respiratory heart failure in cardiosurgical patients].

The possibility of performing the recruiting artificial ventilation technique with a high plateau and positive end-expiratory pressure was studied in 32 cardiosurgical patients, including those with cardiovascular insufficiency. The lung opening maneuver, by using the artificial ventilation adjustable by pressure and the monitoring peak pressure, PDKV, tidal volume, and dynamic compliance, by accurately determining the points of opening and closure is the method of choice in alveolar recruitment. This method permits a significant improvement of arterial oxygenation and dynamic compliance of the lung in patients with acute respiratory failure.

[Using non-invasive mask lung ventilation in cardiosurgical patients with acute respiratory distress syndrome].

Twenty patients aged 33 to 71 (54 +/- 6) years (male - 13, female - 7) operated on the heart and main vessels were included in the case study. I.e.
