Rotating the magnetization of a shape anisotropic magnetostrictive nanomagnet with voltage-generated stress/strain dissipates much less energy than most other magnetization rotation schemes, but its application to writing bits in non-volatile magnetic memory has been hindered by the fundamental inability of stress/strain to rotate magnetization by full 180(o). Normally, stress/strain can rotate the magnetization of a shape anisotropic elliptical nanomagnet by only up to 90(o), resulting in incomplete magnetization reversal...

Background: Cancer screening rates are lower in Japan than in Western countries such as the United States and the United Kingdom. While health professionals publish pro-cancer-screening messages online to encourage proactive seeking for screening, anti-screening activists use the same medium to warn readers against following guidelines. Contents of pro- and anti-cancer-screening sites may contribute to readers’ acceptance of one or the other position. We aimed to use a text-mining method to examine frequently appearing contents on sites for and against cancer screening...

The clinical effectiveness of patient-controlled analgesia has been demonstrated in a variety of settings. However, patient-controlled analgesia is rarely utilised in the emergency department. The aim of this study was to compare the cost-effectiveness of patient-controlled analgesia vs. standard care in participants admitted to hospital from the emergency department with pain due to traumatic injury or non-traumatic abdominal pain. Pain scores were measured hourly for 12 h using a visual analogue scale. Cost-effectiveness was measured as the additional cost per hour in moderate to severe pain avoided by using patient-controlled analgesia rather than standard care (the incremental cost-effectiveness ratio)...

Speech perception can improve substantially with practice (perceptual learning) even in adults. Here we compared the effects of four training protocols that differed in whether and how task difficulty was changed during a training session, in terms of the gains attained and the ability to apply (transfer) these gains to previously un-encountered items (tokens) and to different talkers. Participants trained in judging the semantic plausibility of sentences presented as time-compressed speech and were tested on their ability to reproduce, in writing, the target sentences; trail-by-trial feedback was afforded in all training conditions...

The ability to create 3D tissues from induced pluripotent stem cells (iPSCs) is poised to revolutionize stem cell research and regenerative medicine, including individualized, patient-specific stem cell-based treatments. There are, however, few examples of tissue engineering using iPSCs. Their culture and differentiation is predominantly planar for monolayer cell support or induction of self-organizing embryoids (EBs) and organoids. Bioprinting iPSCs with advanced biomaterials promises to augment efforts to develop 3D tissues, ideally comprising direct-write printing of cells for encapsulation, proliferation, and differentiation...

Two carbon-rich ruthenium complexes bearing a dithienylethene (DTE) unit and a hexylthiol spacer were designed to be attached on gold surfaces. Both compounds display photochemically-driven switching properties, allowing reversible conversion from open to closed forms of the DTE units upon irradiation in solution. In contrast, only the bimetallic complex undergoes an efficient electrochemical ring closure at low potential, (0.5 V vs SCE), whereas the monometallic complex show a simple one electron reversible redox event...

We present a self-assembled template of tetraphenylmethane-based variants on a Au(111) surface which feature a periodic lateral arrangement of acetyl groups sticking out of the molecular film. Using the tip of a scanning tunneling microscope, this acetyl group can be removed in a spatially controlled way without a significant effect on the remaining molecular assembly. The chemically modified molecule can readily be distinguished from the original ones such that information can be engraved in the molecular film...

This historical study aims to refine understanding of the nature of nursing work. The study focuses on the 1880 crisis at Guy's Hospital in London to examine the nature and meaning of nursing work, particularly the concept of nursing work as many 'little things.' In this paper, an examination of Margaret Lonsdale's writing offers an original contribution to our understanding of the ways in which nursing work differs from medical practice. In this way, we use the late-nineteenth-century controversy at Guy's Hospital as a prism through which to examine the contested nature of nursing work...

Automatic structure elucidation of small molecules by means of the "Logic for Structure Elucidation" software (LSD) is introduced in the context of the automatic exploitation of chemical shift correlation data and with minimal input from chemical shift values. The first step in solving a structural problem by means of LSD is the extraction of pertinent data from the 1D and 2D spectra. This operation requires the labeling of the resonances and of their correlations; its reliability highly depends on the quality of the spectra...

Presidential commissions come and go by design, and it is reasonable to wonder about the impact of their recommendations. I have been involved in the work of two presidential commissions: as a member of the Advisory Committee on Human Radiation Experiments (from 1994 to 1995) and as senior consultant to the National Bioethics Advisory Commission (from 1999 to 2000) for its report on multinational research. I continue to reflect on and look for the impact of both these commissions. ACHRE's charter included the review of experiments with ionizing radiation sponsored or conducted by the United States government since the 1940s...

Shortly after the Presidential Commission for the Study of Bioethical Issues was constituted in 2010 and days before the commission members were to join a conference call to discuss possible topics for their deliberation, Craig Venter held a press conference announcing that his lab had created a synthetic chromosome for a species of mycoplasma and had inserted this genetic material into organisms of another species of mycoplasma (the genes of which had been deactivated), transforming the host species into the donor species...

This is a paper showing how a concept central to the work of Wilfred Bion, and one of Klein's important recommendations concerning the practice of analysis with adults and small children, can both be seen in the light of Freud's earliest formulation of the origin of anxiety and the mother's first responses to her infant in distress. In the paper I suggest that these clinically influential concepts of Klein and Bion show an underlying consistency and affinity with Freud's early ideas about the management of anxiety in the mother-infant relationship, described in two of his pre-psychoanalytic writings, How Anxiety Originates (1894b), and The Project for a Scientific Psychology (1950 [1895])...

Given that an estimated 0.6% of the U.S. population is transgender (trans) and that large health disparities for this population have been documented, government and research organizations are increasingly expanding measures of sex/gender to be trans inclusive. Options suggested for trans community surveys, such as expansive check-all-that-apply gender identity lists and write-in options that offer maximum flexibility, are generally not appropriate for broad population surveys. These require limited questions and a small number of categories for analysis...

Academic self-concept (ASC) is comprised of individual perceptions of one's own academic ability. In a cross-sectional quasi-representative sample of 3,779 German elementary school children in grades 1 to 4, we investigated (a) the structure of ASC, (b) ASC profile formation, an aspect of differentiation that is reflected in lower correlations between domain-specific ASCs with increasing grade level, (c) the impact of (internal) dimensional comparisons of one's own ability in different school subjects for profile formation of ASC, and (d) the role played by differences in school grades between subjects for these dimensional comparisons...

The current study examined the effect of academic interventions and modifications on behavioral outcomes in a meta-analysis of 32 single-case design studies. Academic interventions included modifying task difficulty, providing instruction in reading, mathematics, or writing, and contingent reinforcement for academic performance. There was an overall small to moderate effect (ϕ = .56) on behavioral outcomes, with a stronger effect on increasing time on task (ϕ = .64) than on decreasing disruptive behavior (ϕ = ...

Breast cancer is the most common cancer affecting women in South Africa. There is little knowledge of beliefs to help identify key areas to improve support and education in this demographically and culturally diverse population. Women with a variety of demographic and socioeconomic characteristics accessing care for breast cancer were asked their agreement to statements of knowledge and beliefs about breast cancer. Of the 259 participants, positive statements of medical cure (87.9%) and family support (90.5%) were most commonly believed...
