OBJECTIVE Life-threatening danger is assumed to produce, in tandem, increases in both vigilance toward threat and stress-related symptoms, but no data test the validity of this assumption. The authors examined associations, in real time, among imminent life-threatening danger, stress-related symptoms, and vigilance. METHOD Symptoms of posttraumatic stress(More)
This study examined rapid orthographic learning following silent reading in third-grade children as a function of number of target nonword repetitions and test delay. In each of two test sessions at least 6 days apart, children read a series of short stories, with each story containing a different nonword repeated either four or eight times. In the second(More)
Advances in three-dimensional (3D) electron microscopy (EM) and image processing are providing considerable improvements in the resolution of subcellular volumes, macromolecular assemblies and individual proteins. However, the recovery of high-frequency information from biological samples is hindered by specimen sensitivity to beam damage. Low dose electron(More)
The thickness of silicon dioxide that is used as the transistor gate dielectric in most advanced memory and logic applications has decreased below 7 nm. Unfortunately, the accuracy and reproducibility of metrology used to measure gate dielectric thickness during manufacture of integrated circuits remains in some dispute. In addition, detailed materials(More)
The introduction of corneal cross-linking (CXL) has changed the landscape of treatment and management of keratoconus and ectasia after refractive surgery. Previously, treatment options provided only temporary visual rehabilitation without limiting disease progression. Keratoconus and ectasia resulted in significant vision-related reduction in quality of(More)
Selective degradation of block copolymer templates and backfilling the open mesopores is an effective strategy for the synthesis of nanostructured hybrid and inorganic materials. Incorporation of more than one type of inorganic material in orthogonal ways enables the synthesis of multicomponent nanomaterials with complex yet well-controlled architectures;(More)
Postinfarction ventricular septal defect (VSD) is a rare complication after acute myocardial infarction, with an incidence rate of 1-2% of all myocardial infarcts (Hutchins, 1979). It is a medical emergency with sobering survival numbers, having a mortality rate of 70-80% within two weeks of the incident event (Bouchart et al., 1998). Cardiac surgery is(More)
A 46-year-old woman presented with a 6-month history of dyspnea and weight loss on a background of previous pneumonectomy for bronchial adenoid cystic carcinoma 14 years beforehand. Several years prior to this presentation, she had developed left vocal cord palsy and a metastatic lesion to the right buttock confirmed at resection. Investigations included CT(More)
Purpose. This paper describes an advanced system that combines corneal cross-linking with riboflavin with fluorescence dosimetry, the ability to measure riboflavin diffusion within the cornea both before and during UVA treatment. Methods and Results. A corneal cross-linking system utilizing a digital micromirror device (DMD) was assembled and used to(More)
