Abstract

We present first results from radio observations with the Murchison Widefield Array seeking to constrain the power spectrum of 21 cm brightness temperature fluctuations between the redshifts of 11.6 and 17.9 (113 and 75 MHz). 3 h of observations were conducted over two nights with significantly different levels of ionospheric activity. We use these data to assess the impact of systematic errors at low frequency, including the ionosphere and radio-frequency interference, on a power spectrum measurement. We find that after the 1–3 h of integration presented here, our measurements at the Murchison Radio Observatory are not limited by RFI, even within the FM band, and that the ionosphere does not appear to affect the level of power in the modes that we expect to be sensitive to cosmology. Power spectrum detections, inconsistent with noise, due to fine spectral structure imprinted on the foregrounds by reflections in the signal-chain, occupy the spatial Fourier modes where we would otherwise be most sensitive to the cosmological signal. We are able to reduce this contamination using calibration solutions derived from autocorrelations so that we achieve an sensitivity of 104 mK on comoving scales k ≲ 0.5 h Mpc[superscript −1]. This represents the first upper limits on the 21 cm power spectrum fluctuations at redshifts 12 ≲ z ≲ 18 but is still limited by calibration systematics. While calibration improvements may allow us to further remove this contamination, our results emphasize that future experiments should consider carefully the existence of and their ability to calibrate out any spectral structure within the EoR window., National Science Foundation (U.S.) (AST-0457585), National Science Foundation (U.S.) (AST-0821321), National Science Foundation (U.S.) (AST-1105835), National Science Foundation (U.S.) (AST-1410719), National Science Foundation (U.S.) (AST-1410484), National Science Foundation (U.S.) (AST-1411622), National Science Foundation (U.S.) (AST-1440343), National Science Foundation (U.S.) (1122374), National Science Foundation (U.S.) (PHY-0835713), National Science Foundation (U.S.) (CAREER-0847753), National Science Foundation (U.S.) (AST-0908884), United States.

Abstract

A cytologic method for sampling the normal breast by fine-needle aspiration (FNA) was used to determine the frequency of clinically inapparent proliferative breast disease (PBD) in women with family histories of breast cancer. The authors attempted to obtain specimens from each quadrant of both breasts in 51 female first-degree relatives of breast cancer patients. The study group had no detectable masses by physical examination or mammography. Samples were prepared on membrane filters, Papanicolaou stained, and evaluated cytomorphologically. Three hundred seventy-eight of 408 (92.6%) possible quadrants were sampled; cellular material was obtained from 290 (76.7%) quadrants. PBD was identified in 20 of the 51 women (39.2%). When epithelium was obtained, nuclear area, perimeter, and diameter were measured with the use of computerized image analysis. Nuclei in samples containing atypical hyperplasia showed significant differences in these parameters when compared with cells from samples containing normal epithelium or benign hyperplasia. The authors' findings indicate that FNA sampling and computerized image analysis are useful in the detection and characterization of clinically inapparent PBD.

Abstract

The two methods of preparing sputum specimens for cytologic study, the (fresh) pick-and-smear technique and the (blended) Saccomanno technique, were compared using 249 consecutive specimens. Two slides were prepared for each specimen by each technique. Of the specimens, 103 showed squamous metaplasia, carcinoma in situ or carcinoma. A semiquantitative rating system (0 to 4+) was used to determine the number of diagnostic cells for each method for those 103 cases. More diagnostic cells were found on the Saccomanno preparations (217) than on the fresh preparations (154). There were 121 diagnostic cells in the Saccomanno preparations versus 95 diagnostic cells in the fresh preparations from 63 squamous metaplasias; 7 versus 3 for the preparations from 5 carcinomas in situ; 64 versus 42 from 28 squamous cell carcinomas; 3 versus 1 from 1 large cell undiffernomas; and 12 diagnostic cells in Saccomanno preparations versus 5 in fresh preparations from 3 small cell cancers. Twelve squamous metaplasias, two carcinomas in situ, four squamous carcinomas, one adenocarcinoma and one small cell cancer had no diagnostic cells on the fresh preparations; four squamous metaplasias and one squamous carcinoma had no diagnostic cells on the Saccomanno preparations. More diagnostic information and fewer false-negative results were achieved with the Saccomanno technique.

Abstract

After discussing the problems of elderly amputees with a peripheral vaxcular surgeon, some of the relevant literaure is surveyed, with views from different specialists, none of whom claim understanding nor consistent success in treatment of phantom limb complaints at present. Dorsal column stimulation has still to be evaluated. Psychological aspects indicate a need for a multidisciplinary team approach to this problem.
