We modified the conventional Pudendal Thigh Flap (PTF) on the vaginoplasty including reconstruction of vaginal vestibule. After the operation, no stenosis of the vaginal vestibule and opening of the vagina was observed. It is believed that our technique is cosmetically and functionally possible and a useful method.

Abstract This paper presents the ONCLE (One Clock Ensemble) solution for Galileo time and frequency reference system with advanced features in terms of robustness, performance, continuity, simplicity. Each component clock is frequency-steered to ensemble time, which itself creates an average those steered outputs, while faults are detected corrected real within integrated system. The f...

An increasing number of studies around the world are showing that a long-held assumption rock fragments (RFs) inert with respect to water retention is incorrect. Yet very few pedotransfer functions (PtFs) account for held by RFs or effect have on fine earth. The PtFs incorporate content (WC) relied upon measurement methods may not be representative field conditions. This indicates gap in resear...

S ENSOR failure can have catastrophic consequences when the measurements are used for control. For example, failures of pitot probes for airspeed measurement have resulted in several major aircraft disasters [1]. Consequently, there is a pressing need to continually diagnose the health of sensors to ensure reliable controlsystem operation [2–5]. Various techniques can be used to detect a sensor...

The paper considers the digital control of a continuous-time process under stochastic disturbances. The problem consists in finding a controller that guarantees a certain performance of the closed loop, while the disturbances belong only to a given class of disturbances. The digital controller has two parts with different sampling rates, where one rate is a multiple of the other one. The soluti...

The Precise Time Facility (PTF) of the Royal Observatory of Belgium (ROB) contains presently 4 Cesium clocks HP5071A, one with standard tubes (since 1995), and three with High Perf. Tubes (since 2012), and one active H-maser CH175A (since 2006). UTC(ORB) is generated from the CH1-75A frequency, steered weekly upon the rapid UTC values. Due to an important maser failure, UTC(ORB) was generated b...

The adoption of tillage during summer fallow can effectively store precipitation in and increase the soil water content dryland wheat fields eastern Loess Plateau; however, its influencing mechanism is still unknown. Three measures were implemented 2018, namely, no-tillage (NTF), subsoiling (STF), plough (PTF), to investigate changes porosity different growth periods winter their contribution s...
