Traditional rotary drilling for planetary rock sampling, in-situ analysis and sample return, is challenging because the axial force and holding torque requirements are not necessarily compatible with lightweight spacecraft architectures in low-gravity environments. This article seeks to optimize an ultrasonic-percussive drill tool to achieve rock penetration with lower reacted force requirements, with a strategic view towards building an Ultrasonic Planetary Core Drill (UPCD) device. The UPCD is a descendant of the Ultrasonic/Sonic Driller/Corer (USDC) technique...

INTRODUCTION: The efficacy of a series of interventions to reduce risk of alcohol-exposed pregnancies is well-established, yet some subsets of women remain at risk. For instance, in CHOICES, a randomized clinical trial of an intervention to prevent alcohol-exposed pregnancy, nondepressed women reduced risk drinking at roughly twice the rate of women with depression (49% vs. 24%). This secondary analysis of CHOICES data examines constructs that can explicate differences between nondepressed and depressed women in the process of changing alcohol behavior...

REVIEW
Khullat Munir, Ilse Worm
In the aftermath of the Ebola crisis and with renewed attention to resilient health systems, the process of improving approaches of global health actors to health systems strengthening is of great relevance. Despite the increased amount of attention paid to health systems strengthening, there is no standard definition of this concept among global health actors. Germany is no exception. Though there have been recent commitments to increase resources allocated to health systems strengthening, German Development Cooperation has no comprehensive strategy for its pursuit...

Patrick K W Chan, Ronald A Li
Electronic pacemakers have been used in patients with heart rhythm disorders for device-supported pacing. While effective, there are such shortcomings as limited battery life, permanent implantation of catheters, the lack of autonomic neurohumoral responses, and risks of lead dislodging. Here we describe protocols for establishing porcine models of sick sinus syndrome and complete heart block, and the generation of bioartificial pacemaker by delivering a strategically engineered form of hyperpolarization-activated cyclic nucleotide-gated pacemaker channel protein via somatic gene transfer to convert atrial or ventricular muscle cardiomyocytes into nodal-like cells that rhythmically fire action potentials...

Nuclear emergency planning arrangements in the UK are continually kept under review. This work proposes to outline how experience from nuclear exercises and undertaking emergency response duties can be based on radiological knowledge of specific sites and utilised in the future. In 2014, the UK regulator, the Office for Nuclear Regulation (ONR) revised their principles for the determination of off-site emergency planning areas around nuclear sites where predetermined countermeasures and other protection measures are applied to protect those people who may be affected by a radiation emergency...

As demand for nurse practitioners in all types of intensive care units continues to increase, ensuring successful integration of these nurses into adult and pediatric general and specialty intensive care units poses several challenges. Adding nurse practitioners requires strategic planning to define critical aspects of the care delivery model before the practitioners are hired, develop a comprehensive program for integrating and training these nurses, and create a plan for implementing the program. Key strategies to ensure successful integration include defining and implementing the role of nurse practitioners, providing options for orientation, and supporting and training novice nurse practitioners...

C Richard Chapman, Charles J Vierck
The nature of the transition from acute to chronic pain still eludes explanation, but chronic pain resulting from surgery provides a natural experiment that invites both clinical epidemiological investigation and basic scientific inquiry into the mechanisms of this transition. The primary purpose of this paper is to review current knowledge and hypotheses on the transition from acute to persistent postsurgical pain, summarizing literature on clinical epidemiological studies of persistent postsurgical pain development, as well as basic neurophysiological studies targeting mechanisms in the periphery, spinal cord, and brain...

: Reliable quantification of low-abundance proteins in complex proteomes is challenging largely owing to the limited number of spectra/peptides identified. In this study we developed a straightforward method to improve the quantitative accuracy and precision of proteins by strategically retrieving the less confident peptides that were previously filtered out using the standard target-decoy search strategy. The filtered-out MS/MS spectra matched to confidently-identified proteins were recovered, and the peptide-spectrum-match FDR were re-calculated and controlled at a confident level of FDR≤1%, while protein FDR maintained at ~1%...

PURPOSE OF STUDY: The medical record is a sea of information that can reveal what patients are trying to tell us about their health condition. It can reveal hints and trends as to why veterans with congestive heart failure (CHF) are being readmitted within 30 days after hospital discharge. These hints and trends lead caregivers to key contributing variables to veterans' readmission. Furthermore, these variables can be used to predict patient outcomes such as readmission and even prognosis...
