The management of herniated lumbar intervertebral disc for patients not responding to an initial trial of conservative therapy is generally surgical. Little is known about the effect of continued conservative therapy on patients who have not improved or have deteriorated within the first 3 months. This study assessed which form of treatment, surgical or(More)
THz CMOS imagers integrated with hyperhemispherical Si-lenses are presented and characterized. FPAs are implemented in 65nm CMOS bulk and SOI technologies. Lens-integrated detectors at 0.65 THz show an increase of 15dB and 20dB in SNR compared to front-side illumination for SOI and bulk respectively. The responsivities R<inf>v</inf> are increased and a(More)
Non-ionizing terahertz imaging using solid-state integrated electronics has been gaining increasing attention over the past few years. However, there are currently several factors that deter the implementations of fully-integrated imaging systems. Due to the lack of low-noise amplification above f max , the sensitivity of THz pixels on silicon cannot match(More)
The successful treatment of a patient with a tumor involves an estimate of weakening due to the tumor and a consideration of the probability of gross fracture through that defect. Weakening due to an open section defect usually results in fracture. Holes produce a stress concentration that is of concern to the orthopedist in reconstituting such fractures.(More)
—A high-power 320 GHz transmitter using 130 nm SiGe BiCMOS technology (220/280 GHz) is reported. This transmitter consists of a 4 × 4 array of radiators based on coupled harmonic oscillators. By incorporating a signal filter structure called return-path gap coupler into a differential self-feeding oscillator, the proposed 320 GHz radiator simultaneously(More)
Concordant advances in cancer chemotherapy, radiotherapy, and surgical technique have been of apparent benefit to many cancer patients suffering from skeletal involvement at the hip. Consideration of the effects of underlying disease and prior treatment must be evaluated prior to developing a surgical plan. Acetabular involvement can be treated by either(More)
