Proximal junctional kyphosis is an increasingly recognized complication following long-segment posterior spinal fusion for adult spinal deformity. The authors describe a novel technique for interspinous ligament reinforcement at the proximal adjacent levels using a cadaveric semitendinosus tendon graft secured with an Ethibond No. 2 double filament (Ethicon, Somerville, New Jersey) via the Krac...

This paper investigates how a wide dynamic range of performance and power levels can be obtained in commercially available state-of-the-art hybrid FPGAs that include embedded processors. Adaptive voltage and frequency scaling obtained with embedded in-situ detectors is employed to scale performance and power in the FPGA fabric under processor control. The results show that it is possible to obt...

Cost-effective nanotechnology-based waterrepellent treatments for clothing fabrics are now commercially available. The effectiveness of these durable water repellent (DWR) fabric treatments were evaluated for application to military uniforms. The addition of a non-wicking finish to clothing fabric negatively impacts comfort in hot and humid environments. Clothing comfort may be improved by refi...

I. Reinhard,* C. Callegari, A. Conjusteau, K. K. Lehmann, and G. Scoles Department of Chemistry, Princeton University, Princeton, New Jersey 08544 (Received 18 February 1999) Purely rotational transitions of a molecule embedded in large 4He clusters have been detected for the first time. The saturation behavior shows that, in contrast to previous expectations, the microwave line profiles are do...

Electrical double layer supercapacitor is very significant in the field of electrical energy storage which can be the solution for the current revolution in the electronic devices like mobile phones, camera flashes which needs flexible and miniaturized energy storage device with all non-aqueous components. The multiwalled carbon nanotubes (MWNTs) have been synthesized by catalytic chemical vapo...

Before being processed into composites, reinforcement fabrics may undergo repeated involuntary deformation, the complete sequence of which is here referred to as specimen history. To mimic its effect, fabric specimens were subjected to sequences of defined shear operations. For single fabric layers with unconstrained thickness, quantitative evaluation of photographic image data indicated that r...
