Review of radiographic measurements following Austin bunionectomy

This study compared preoperative and postoperative results for selected radiographic measurements of 30 patients undergoing the modified Austin bunionectomy procedure for the correction of hallux abducto valgus. Significant reductions in all postoperative radiographic values were demonstrated, including hallux abductus angle, metatarsus primus adductus angle, tibial sesamoid position, and first metatarsal protrusion distance.     

Optical Under-Sampling and Reconstruction of Several Bandwidth-Limited Signals

We demonstrate experimentally an optical system for under-sampling several bandwidth-limited signals with carrier frequencies that are not known apriori and can be located anywhere within a very broad frequency region between 0-18 GHz. The system is based on under-sampling asynchronously at three different sampling rates. The optical pulses required for the under-sampling are generated by a combination of an electrical comb generator and an electro-absorption optical modulator. To reduce loss and improve performance the implementation of the optical system is based on a wavelength division multiplexing technique. An accurate reconstruction of both the phase and the amplitude was obtained when two chirped signals each with a bandwidth of about 150 MHz were sampled.     

Microlens lithography: A new approach for large display fabrication

Microlens lithography is a new lithographic method, that uses microlens arrays to image a lithographic mask onto a substrate layer. Microlens lithography provides photolithography at a moderate resolution for an almost unlimited area. The imaging system consists of stacked microlens arrays forming an array of micro-objectives. Each micro-objective images a small part of the mask pattern, the images overlap in the image plane. Potential applications for microlens lithography are the fabrication of large area flat panel displays (FPD), color filters, and micromechanics.     

A 3-V 340-mW 14-b 75-Msample/s CMOS ADC with 85-dB SFDR at Nyquistinput

This paper describes the design of a 14-b 75-Msample/s pipeline analog-to-digital converter (ADC) implemented in a 0.35-μm double-poly triple-metal CMOS process. The ADC uses a 4-b first stage to relax capacitor-matching requirements, buffered bootstrapping to reduce signal-dependent charge injection, and a flip-around track-and-hold amplifier with wide common-mode compliance to reduce noise and power consumption. It achieves 14-b accuracy without calibration or dithering. Typical differential nonlinearity is 0.6 LSB, and integral nonlinearity is 2 LSB. The ADC also achieves 73-dB signal-to-noise ratio, and 85-dB spurious-free dynamic range over the first Nyquist band. The 7.8-mm² ADC operates with a 2.7- to 3.6-V supply, and dissipates 340 mW at 3 V     

Contrasting patterns of fantasy and motility in Irish and Italian schizophrenics.

Several hypotheses concerning differences in fantasy and motor activity of schizophrenics of Irish and Italian descent were developed on the basis of anthropological evaluation of cultural patterns and child-rearing practices. Schizophrenics of Irish descent were expected to be more given to imaginative behavior and motor control when compared with those of Italian descent. Psychological instruments used were the Rorschach, Barron's Movement-Threshold Inkblots, TAT, Porteus Mazes, tests of time estimation, motor inhibition, admission-denial of frustration, and ward behavior ratings. 60 male, veteran patients were used as Ss, one-half of Irish and one-half of Italian descent. The results appeared to support the hypothesis of persistent differences in motor and fantasy activity. Implications for review of psychiatric nosology, personality research, and interdisciplinary collaboration were suggested. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Investigating onset, cessation, relapse, and recovery: Why you should, and how you can, use discrete-time survival analysis to examine event occurrence.

Illustrates how discrete-time survival analysis can address questions about onset, cessation, relapse, and recovery. Using data on the onset of suicide ideation and depression and relapse into cocaine use, the authors introduce key concepts underpinning the method, describe the action of the discrete-time hazard model, and discuss several types of main effects and interactions that can be included as predictors. Practical issues of data analysis and strategies for interpretation and presentation are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
