cavity Recent advan.ces in cementless hip replacement surgery have significantly improved the accuracy of bone cavity preparation and custom implant shape design. With the increased accuracy and tighter fit, determining whether the implant can actually be inserted t o its f i nal working position inside ihe cavity during surgery is essential to guarantee full implant functionality. This paper p...

The aim of this study was to evaluate the dissemination of cancer cells at laparoscopic hysterectomy according to the intraperitoneal cytology.Patients with endometrial cancer underwent total laparoscopic modified radical hysterectomy. Peritoneal wash cytology was performed on entering the peritoneal cavity before surgical preparation and just after hysterectomy.Seventy-eight patients underwent...

Current research on micromechanical resonators strives for quantum-limited detection of the motion of macroscopic objects. Prerequisite to this goal is the observation of measurement backaction consistent with quantummetrology limits. However, thermal noise currently dominates measurements and precludes ground-state preparation of the resonator. Here, we establish the collective motion of an ul...

The purpose of the present study was to establish a geometric design method for class I inlay cavities as a future method of computer-aided tooth preparation. Major occlusal fissures were used as a starting point of the cavity design and marked as multiple continuous line segments. An experimental cavity outline was defined by circular arcs and Bézier curves with three design parameters: minimu...

An approach is presented for converting a two-atom singlet state into a three-atom singlet state based on the quantum Zeno dynamics induced by continuous coupling. The scheme can be achieved within one step through appropriately regulating the Rabi frequencies of the classical fields. The effects of decoherence such as atomic spontaneous emission and the loss of cavity are also considered in vi...

Cavity-directed chemical transformations represent one of the most important features in 3-D host chemistry, yet they are unexplored as synthetic receptors. We are developing such functions with the large cavity of self-assembled cages, particularly an M6L4-type cage. The photodimerization of olefins within this cage shows remarkable rate enhancement, perfect regioand stereoselection, and high ...

Optical nonlinearities sensitive to individual photons may be extremely useful as elements in quantum logic circuits for photonic qubits. A much cited example is the work of Turchette et al. [Phys. Rev. Lett. 75, 4710 (1995)], in which a phase shift of about 10 degrees was reported. To improve this result, we propose a single sided cavity geometry with minimal cavity losses. It should then be p...

AIMS To identify promising intervention components intended to help smokers to attain and maintain abstinence in their quit smoking attempts. DESIGN A fully crossed, six-factor randomized fractional factorial experiment. SETTING Eleven primary care clinics in southern Wisconsin, USA. PARTICIPANTS A total of 637 adult smokers (55% women, 88% white) motivated to quit smoking who visited pri...
