The DJEHUTY project is an intensive effort at the Lawrence Livermore National Laboratory (LLNL) to produce a general purpose 3-D stellar structure and evolution code to study dynamic processes in whole stars.
Public health investigations require rapid assessment, response, and initiation of control measures. In 2012, the New Hampshire Department of Health and Human Services used digital pens to rapidly acquire epidemiologic data during a gastrointestinal illness outbreak.
Menus were obtained and a standard questionnaire was administered to exposed persons using digital pens. Questionnaire data were downloaded into an electronic file for analysis.
Sixty-nine (74%) of 93 exposed persons completed a questionnaire. Of 6389 data entries made on digital paper, 218 (3%) required correction; of these, 201 (92%) involved a free-form variable and 17 (8%) involved a check-box variable. Digital pens saved an estimated 5 to 6 hours of data-entry time.
This outbreak provided an opportunity to assess the value of digital pens for decreasing data-entry burden and allowing more timely data analysis in an emergent setting. Depending on the size of the outbreak and complexity of the survey, there is likely a threshold when use of digital pens would provide a clear benefit to outbreak response. As new technology becomes available for use in emergency preparedness settings, public health agencies must continuously review and update response plans and evaluate investigation tools to ensure timely disease control and response activities.

Artificial opal films have been prepared by sedimentation of monodisperse silica spheres in water suspension. Atomic force microscope images show a triangular packing of the spheres at the surface of the films. The presence and the energy position of an optical pseudo gap in incidence-angle-dependent transmittance and reflectance spectra is observed and accounted for by theoretical calculations of the photonic band structure. These calculations indicate that the pseudo gap is due to the splitting of the photonic bands in the L point of the Brillouin zone. The spectroscopic data show additional loss structures due to both other features of the Brillouin zone and the diffraction of the light from the regular surface of the sample. The effect of the infiltration of opals with polydiacetylene solutions is also reported.
Endoscopic endonasal transphenoidal surgery has been recently proposed as a minimally invasive procedure for the treatment of pituitary adenomas. The main objective of the anaesthesiologist is to induce sufficient haemodynamic control together with rapid recovery at the end of surgery. The aim of this study was to examine recovery profile, surgical operative conditions and haemodynamic differences using remifentanil infusion with either propofol target controlled infusion system or sevoflurane.
Forty-four adult patients were enrolled in a prospective, randomized, single-blind, two-group study: Group P received propofol target controlled infusion system and remifentanil; Group S received sevoflurane and remifentanil for maintenance of anaesthesia.
No statistically significant differences between the two groups with regards to the haemodynamic changes, operative conditions as assessed by a four-step bleeding score (0–3), were obtained. Recovery times were considerably shorter after remifentanil–sevoflurane in comparison with remifentanil–propofol target controlled infusion system group (7.4 vs. 12.8 min, P < 0.01).
This study demonstrates that sevoflurane–remifentanil gives a faster recovery and equivalent intraoperative status compared with propofol target controlled infusion system with remifentanil for the endoscopic endonasal transphenoidal approach.
