A strong coupling standing wave, interacting with three-level L-type ~or ladder-type! atoms, can diffract a weak probe field ~propagating along a direction normal to the standing wave! into high-order diffractions, a phenomenon which we name electromagnetically induced grating ~EIG!. We develop in this work a theory for studying EIG in a homogeneously broadened medium consisting of three-level ...

Testicular atrophy is a rare but distressing complication of inguinal hernia repair. Apart from the postsurgical etiology, ischemic orchitis and subsequent testicular atrophy may occur secondary to compression of the testicular vessels by chronically incarcerated hernias. We present a rare case of testicular atrophy secondary to a large long standing incarcerated inguinal hernia of 2-decade dur...

Semiconductor nanowires are promising building blocks for next-generation photonics. Indirect proofs of large absorption cross sections have been reported in nanostructures with subwavelength diameters, an effect that is even more prominent in vertically standing nanowires. In this work we provide a three-dimensional map of the light around vertical GaAs nanowires standing on a substrate by usi...

BACKGROUND Impaired skeletal muscle metabolism is recognized in chronic fatigue syndrome (CFS). This study examined the relationship between skeletal and cardiac muscle function and symptoms on standing in CFS using magnetic resonance spectroscopy (MRS) and impedance cardiography. MATERIALS AND METHODS Phosphocreatine (PCr)/adenosine triphosphate (ATP) ratio by cardiac MRS, PCr/ADP and proton...

We develop a detailed analysis of edge bifurcations of standing waves in the nonlinear Schrödinger (NLS) equation on a tadpole graph (a ring attached to a semi-infinite line subject to the Kirchhoff boundary conditions at the junction). It is shown in the recent work [7] by using explicit Jacobi elliptic functions that the cubic NLS equation on a tadpole graph admits a rich structure of standin...

Numerous motion tests for diagnosing SIJ dysfunction have been described in the literature (van der Wurff et al 2000a & b). None is superior to another illustrating that physiotherapists should be suspicious with regard to the clinical relevance claimed by some authors. In general, motion tests of the SIJ can be reduced to 3 main directions: backward motion of the ilium (‘spine test’), forward ...
