BACKGROUND Locking compress plate, as external fixator, is an attractive technique for distal tibial fracture treatment. But it still remains unclear whether the external LCP has sufficient stiffness. Thus, the present study aims to make a comprehensive evaluation of the stiffness of external locking compress plate when it is used as an external fixator in distal tibial fractures treatment. M...

Given its specific thermal characteristics, the sesquioxide crystal Lu(2)O(3) is a particularly promising laser host material. We demonstrate mode locking of a Yb:Lu(2)O(3) laser by use of a semiconductor saturable-absorber mirror. The laser emits up to 470 mW in the picosecond regime, corresponding to a pump efficiency as high as 32%. With dispersion compensation, pulses as short as 220 fs at ...

USING transesophageal echocardiography, echogenic material can be shown in the right ventricle during many orthopedic procedures. Recently, transcranial Doppler–recorded microembolic signals have been described during femoral fracture fixation, suggesting that medullary pressurization may be associated with systemic microembolism and pulmonary fat and marrow emboli. Although reamed, locked intr...

Minimization of the torsional barrier for phenyl ring flipping in a metal-organic framework (MOF) based on the new ethynyl-extended octacarboxylate ligand H(8)TDPEPE leads to a fluorescent material with a near-dark state. Immobilization of the ligand in the rigid structure also unexpectedly causes significant strain. We used DFT calculations to estimate the ligand strain energies in our and all...

The temperature is measured by the fluorescent lifetime of fluorescent material. In this work, the analog switch was controlled by single chip to trigger exciting light emission of LED. In order to measure the fluorescent lifetime, photoelectric detector, amplifier and active power filter were used. The modulation frequency of fluorescent signal was detected by phase locking detection method. T...

The polarization of highly divergent modes of broad-area square vertical-cavity surface-emitting lasers is shown to be only marginally affected by material anisotropies but determined by an interplay of the polarization properties of the Bragg cavity mirrors and of the transverse boundary conditions. This leads to a locking of the polarization direction to the boundaries and its indeterminacy f...

Oracle Parallel Server (OPS) is a shared disk RDBMS. We present a high level overview of the main architectural issues of OPS and their evolution throughout the releases of the Oracle database. The Oracle relational database can be used either in exclusive or shared mode. In exclusive (the most traditional) mode only one Oracle instance can mount or open the database. The Oracle Parallel Server...
