Strong waveguide Bragg gratings (10.5 dB transmission dip) were fabricated using the femtosecond (fs) laser direct-write technique in ZBLAN glass. The Bragg gratings are based on depressed cladding waveguides and consist of planes, periodic according to the Bragg condition, which are constructed from a transverse hexagonal lattice of smaller point features. ...

A customized IQ modulator driven by equal-amplitude binary signals for generating offset-free 16-quadrature amplitude modulation (QAM) is proposed and validated through simulations. The incorporation of tunable splitters demonstrates the feasibility of the transmitter and enables more efficient constellations such as hexagonal 16-QAM.

Endoscopic treatment of biliary tract complications after Roux-en-Y surgery is still a challenge. With balloon enteroscopy, we can reach previously inaccessible areas changing the management of biliopancreatic diseases in patients with surgically altered anatomy. We report a case of single-balloon enteroscopy plus endoscopic retrograde cholangiopancreatography for the treatment of a ...

Bilberry anthocyanin bearing an ortho-dihydroxyl group on the B-ring was selectively isolated by complex formation with flavocommelin and aluminium ions (Al3+). The interaction between the anthocyanins, flavocommelin and Al3+ might be happened in the similar manner with rigid supramolecules such as commelinin, protocyanin and other complex pigments. Complex blue pigment ...

Hyperconjugation underlies many chemical phenomena of fundamental and practical importance. Owing to a great deal of interest in the anomeric effect, anomeric-like hyperconjugative effects have been thoroughly investigated in oxygen-containing systems. However, such interactions in the second- and third-row chalcogens are less well understood and have generated some controversy. Here, ...

SUMMARY:: Occipital lobe epilepsies (OLEs) manifest with occipital seizures from an epileptic focus within the occipital lobes. Ictal clinical symptoms are mainly visual and oculomotor. Elementary visual hallucinations are common and characteristic. Postictal headache occurs in more than half of patients (epilepsy-migraine sequence). Electroencephalography (EEG) is of significant diagnostic value, ...

We propose and experimentally demonstrate a simplified coherent receiver based on heterodyne detection with only two balanced photodetectors and two analog-to-digital converters. The polarization diversity hybrid can be simplified relative to the conventional one. The detected intermediate frequency signals are first downconverted to baseband with inphase and quadrature separation. Using ...

ABSTRACT: Adenosine-5'-phosphosulfate kinase (APSK) catalyzes the phosphorylation of adenosine-5'-phospho-sulfate (APS) to 3'-phospho-APS (PAPS). In plants, this enzymatic activity is biochemically regulated through an intersubunit disulfide bond between Cys86 and Cys119 in the N-terminal loop of APSK. To examine if O(3P) generat-ed by the photodeoxygenation of 2,8 dihydroxymethyldibenzothiophene S oxide could ...

Two novel routes based on [5C + 1N] annulations for the synthesis of 2,3-dihydrofuro[3,2-c]pyridines are described. Ammonium acetate (NH(4)OAc) is used as an ammonia source in both routes. The first route utilizes 1-acyl-1-[(dimethylamino)alkenoyl]cyclopropanes as a five-carbon 1,5-bielectrophilic species and combines the [5C + 1N] annulation and regioselective ring-enlargement of cyclopropyl ...

The adhesive properties of a material can be greatly affected simply by wrinkling its surface. We show the importance of selecting the wrinkle feature sizes (amplitude, b and wavelength, λ) that complement the materials-defined length scale related to the adhesion energy and modulus. A rigid circular cylindrical punch patterned with ...

The results of the federal election of 2012 will likely have very substantial impacts on the practice of radiology. Health care reform is likely to continue under the administration of either of the two major candidates, albeit in very different ways. In particular, radiologists should be aware of the candidates' ...

A simple and compact point-diffraction interferometer with circular common-path geometry configuration is developed. The interferometer is constructed by a beam-splitter, two reflection mirrors, and a telescope system composed by two lenses. The signal and reference waves travel along the same path. Furthermore, an opaque mask containing a reference pinhole and ...

Quantum-optical coherence tomography (QOCT) combines the principles of classical OCT with the correlation properties of entangled photon pairs [Phys. Rev. A65, 053817 (2002)]. The standard QOCT configuration is based on the Hong-Ou-Mandel interferometer, which uses entangled photons propagating in separate interferometer arms. This noncollinear configuration imposes practical limitations, e.g., misalignment ...
