Abstract: An apparatus, system, and method for an excimer laser having lasing gas and electron emitters emitting electrons upon the application of an emitting voltage is described herein.

Abstract: Optical waveguides with power monitoring or optical detection capabilities are disclosed. The waveguide includes a lower cladding, a core disposed on the lower cladding, an upper cladding disposed on the core and a trench extending transversely through a distal end of the lower cladding, core and upper cladding. The trench includes a distal wall that provides a reflective surface disposed at an angle relative to the end of the core of greater than 90°. A detector is disposed above the trench for receiving a reflected light beam off of the reflective surface. Various methods of manufacturing these devices are also disclosed.

Abstract: An intestinal lengthening device and method for lengthening the intestine of infants and neonates. The method steps include: resecting a section of intestine to be lengthened; closing the one end of the intestine section, preferably the proximal end, and attaching the other end to an opening in the abdominal wall to form a fistula with stoma; allowing the attachments to heal; attaching the intestinal lengthening device; applying and maintaining 5-20 kPa of tension to the device; allowing the gut to rest for 7 days when the desired length is reached; removing the intestinal lengthening device; reattaching the intestinal section to the intestine. The device includes an inserted end that attaches to the mucosal surface of an intestinal section, an abdominal end that attaches to the abdomen of the patient, and a tension rod to incrementally increase the distance between the two ends. An in situ device includes a sealed tension rod between 2 expansion tips.

Abstract: An electro-optic modulator comprises two electrodes and a waveguide. The waveguide is formed between the electrodes in the presence of an electric field.

Abstract: The invention provides methods for designing lenses useful for correcting presbyopia, lenses incorporating such designs and methods for producing these lenses. The lenses of the invention exhibit a better distribution of the distance and near vision powers within the multifocal zone and, thus, improved visual acuity and wearer satisfaction.

Abstract: The invention relates to an anhydrous crystalline form of (2-[2-amino-1,6-dihydro-6-oxo-purin-9-yl)methoxy]ethyl L-valinate hydrochloride (otherwise known as valaciclovir hydrochloride) and a process for preparing it.

Abstract: An attenuated enterovirus or rhinovirus, suitable for use as a vaccine, has a reversed base pairing in the part, or in a part corresponding to the part, of the 5' non-coding region of the genome of poliovirus type 3 Leon strain shown below: ##STR1## A suitable attenuated poliovirus has the bases G and C at positions 469 and 534 respectively for a type 1 or type 2 poliovirus or at positions 472 and 537 respectively for a type 3 poliovirus.

Abstract: An attenuated enterovirus or rhinovirus, suitable for use as a vaccine, has an attenuating mutation at least at a position which is, or corresponds with, position 471 or 484 of the genome of poliovirus type 3 Leon strain.

Abstract: An attenuated enterovirus or rhinovirus, suitable for use as a vaccine, has an attenuating mutation at least at a position which is, or corresponds with, position 479 and/or 482 of poliovirus type 3 Leon strain.
