Non-adiabatic quantum electrodynamic effects on electron-nucleus-photon systems: Single photonic mode vs infinite photonic modes.

The quantum-electrodynamic non-adiabatic emission (QED-NAE) is a type of radiatively assisted vibronic de-excitation due to electromagnetic vacuum fluctuations on non-adiabatic processes. Building on our previous work [Tsai et al., J.

Effects of Non-Adiabatic Electromagnetic Vacuum Fluctuations on Internal Conversion.

To explore non-adiabatic effects caused by electromagnetic (EM) vacuum fluctuations in molecules, we develop a general theory of internal conversion (IC) in the framework of quantum electrodynamics and propose a new mechanism, "quantum electrodynamic internal conversion" (QED-IC). The theory allows us to compute the rates of the conventional IC and QED-IC processes at the first-principles level. Our simulations manifest that, under experimentally feasible weak light-matter coupling conditions, EM vacuum fluctuations can significantly affect IC rates by an order of magnitude.

Quantitative diffusion-weighted magnetic resonance imaging for the diagnosis of partial-thickness rotator cuff tears.

Background: This study investigated diffusion-weighted (DWI) magnetic resonance imaging (MRI) as an alternative to fat-suppressed T2-weighted imaging (FS-T2WI) for assessment of partial-thickness rotator cuff tears (RCTs).

Methods: Patients with arthroscopy proven partial-thickness RCTs who also received MRI (FS-T2WI and DWI) before surgery were prospectively included. Receiver operating characteristic curves were used to compare DWI vs.

Extraction equilibrium of indium(III) from nitric acid solutions by di(2-ethylhexyl)phosphoric acid dissolved in kerosene.

The extraction equilibrium of indium(III) from a nitric acid solution using di(2-ethylhexyl) phosphoric acid (D2EHPA) as an acidic extractant of organophosphorus compounds dissolved in kerosene was studied. By graphical and numerical analysis, the compositions of indium-D2EHPA complexes in organic phase and stoichiometry of the extraction reaction were examined. Nitric acid solutions with various indium concentrations at 25 °C were used to obtain the equilibrium constant of InR₃ in the organic phase.

Stabilization of the proximal ulnar stump after the Darrach or Sauvé-Kapandji procedure by using the extensor carpi ulnaris tendon.

The Darrach and Sauvé-Kapandji procedures are considered to be useful treatment options for distal radioulnar joint disorders. Postoperative instability of the proximal ulnar stump and radioulnar convergence, however, may cause further symptoms. From October 1999 to May 2002, a total of 19 wrists in 15 men and four women, with an average age of 48.

Surgical outcome of volar plate arthroplasty of the proximal interphalangeal joint using the Mitek micro GII suture anchor.

Background: The mechanism of injury in dorsal dislocation is usually a hyperextensive stress simultaneous with some degree of longitudinal compression. Operative treatment is indicated for those unstable and reduction is not achieved. We report the surgical outcome of volar plate arthroplasty of the proximal interphalangeal (PIP) joint using the Mitek Micro GII suture anchor.

Extensor-tendons reconstruction using autogenous palmaris longus tendon grafting for rheumatoid arthritis patients.

Background: The purpose of the study is to retrospectively review the clinical outcome of our study population of middle-aged RA patients who had suffered extensor-tendon rupture. We reported the outcome of autogenous palmaris tendon grafting of multiple extensor tendons at wrist level in 14 middle-aged rheumatoid patients.

Methods: Between Feb.

Combined extraforaminal and intradiscal cement leakage following percutaneous vertebroplasty.

Study Design: A case report and review of the literature are presented.

Objective: To describe an extremely rare case of combined extraforaminal and intradiscal cement leakage in different vertebral levels following percutaneous vertebroplasty.

Summary Of Background Data: Cement leaks in vertebroplasty are relatively common but generally not clinically significant.

Dorsal ganglion of the wrist: results of treatment by arthroscopic resection.

Between September 1997 and September 2000, 32 patients (20 males and 12 females; average age 23.7 years) received arthroscopic surgery for dorsal wrist ganglion. Five of the patients (15.
