We demonstrate that a single photon with an optimal temporal waveform can be efficiently loaded into a cavity. Using heralded narrow-band single photons with exponential growth wave packet shaped by an electro-optical amplitude modulator, whose time constant matches the photon lifetime in the cavity, we demonstrate a loading efficiency of (87±2)% from free space to a single-sided Fabry-Perot ca...

The dome-shaped radiopaque shadows frequently seen on the floor of the maxillary sinus, and sometimes inaccurately referred to as antral mucoceles, appear to represent focal accumulation of inflammatory exudate that lifts the epithelial lining of the sinus and the periosteum away from the underlying bone to form the characteristically shaped structures. Their histologic appearance is therefore ...

BACKGROUND The first Lippes Loop intrauterine device (IUD) was introduced in 1962. It was a plastic double "S" loop, a trapezoid shaped IUD that closely fit around the contours of the uterine cavity, reducing the incidence of expulsion. This IUD was commonly used from the 1960's to the 1980's. Some authors state that the IUD can be left in the uterine cavity for an indefinite amount of time. Pr...

INTRODUCTION Peritoneal loose body(PLB) is usually small, therefore giant Peritoneal loose body(gPLB) with a diameter >5cm has rarely been described in the literatures. We report a case of two gPLB simultaneously found in one patient. PRESENTATION OF CASE A healthy 79-year-old man palpated himself a solid mass with alternating localizations in his peritoneal cavity 6 months ago. It was not th...

BACKGROUND Remote ballistic femoral fractures are rare fractures reported in the literature but still debated as to their existence and, indeed, their treatment. This study aimed to prove their existence, understand how they occur and determine which ammunition provides the greatest threat. In addition, fracture patterns, soft tissue disruption and contamination were assessed to aid in treatmen...

In this work, we numerically study laminar flows in forced convection a U -shaped channel. Our was based on finite volume method by the fluent code carried out for Reynolds number varying range 100<Re<700, and Rayleigh Ra=105 Prandtl Pr=0.72. As function of number, results obtained are presented form thermal dynamic field, variation Nusselt speed average temperature at outlet channel as R...
