We demonstrate a novel alignment-free all-fiber source for generating telecom-band polarization-entangled photon pairs. Polarization entanglement is created by injecting two relatively delayed, orthogonally polarized pump pulses into a piece of dispersion-shifted fiber, where each one independently engages in four-photon scattering, and then removing any distinguishability between the correlate...

The effects of the residual proton-neutron interactions on bandcrossing features are studied by means of shell model calculations for nucleons in a high-j intruder orbital. The presence of an odd-nucleon shifts the frequency of the alignment of two nucleons of the other kind along the axis of rotation. It is shown that the anomalous delayed crossing observed in nuclei with aligning neutrons and...

Treatment of acute ankle fractures is clear in the approach; however, questions about delayed repair of chronic malunited ankle fractures still remain. Illustrated here is a case report of a 49 year old female that presented with a bimalleolar malunion, with severe lateral talar displacement and valgus position. She presented to our clinic 8 months following the initial injury. In the presence ...

The current report reviews a case of mixed dental trauma consequent to a fall by an older patient. The patient's teeth were forced out of alignment by the trauma and suffered pulpal necrosis. Treatment involved not only healing the acute injuries, but also attending to some subtle delayed problems that became apparent during treatment. Treatments involving endodontics, periodontics, orthodontic...

This retrospective study evaluated the surgical management of 117 tibial plateau fractures treated between 1990 and 1998. At last patient follow-up, results were rated good to excellent in 94, fair in 13, and poor in 10 cases. Follow-up radiographs showed degenerative changes in the lateral compartment in 29 cases. Other complications included five wound infections, two deep venous thromboses, ...

Four idealized direct numerical simulations are performed to examine the dynamics arising from the superposition of a monochromatic gravity wave (GW) and sinusoidal linear and rotary fine structure in the velocity field. These simulations are motivated by the ubiquity of such multiscale superpositions throughout the atmosphere. Three simulations explore the effects of linear fine structure alig...

normal axial alignment restoration in lower extremities is crucial for surgeons performing reconstructive surgeries. since reference normal values of axial alignment are affected by age, sex, and ethical issues, we tried to scrutinize these parameters in iranian adults and compare them with normal values in literatures. through a cross-sectional design, standing axial alignment views of lower e...

In Pierrehumbert (1980) three rising accents are posited for English, H*, L+H* and L*+H, but this three-way contrast has often been disputed. In the present experiment, Minnesotan and Southern Californian speakers read two dialogs which included four levels of emphasis. Emphasis lengthened segmental duration, raised the scaling of all tones and delayed H alignment in L+H*. Independently of emph...

We have measured the alignment of the photofragments produced by photodissociation of Hg-Ar van der Waals molecules using light around 253.7 nm. The molecules are produced in the X0+ ground state in a supersonic expansion. Tunable laser light close to the Hg 6 ‘Se-6 3P, transition is then used to excite the molecule to the Bl* state, in which it dissociates. The alignment of the resulting Hg( 3...
