Counterfeiting of valuable certificates, documents, and banknotes is a serious issue worldwide. As a result, the need for developing novel anticounterfeiting materials is greatly increasing. Herein, we report a new kind of ultralong hydroxyapatite nanowire (HAPNW)-based paper with luminescence, fire resistance, and waterproofness properties that may be exploited for anticounterfeiting applications. In this work, lanthanide-ion-doped HAPNWs (HAPNW:Ln(3+)) with lengths over 100 μm have been synthesized and used as a raw material to fabricating a free-standing luminescent, fire-resistant, water-proof paper through a simple vacuum filtration process...

Paper-based microfluidic biosensors have recently attracted increasing attentions in point-of-care testing (POCT) territories benefiting from their affordable, accessible and eco-friendly features, where technologies for fabricating such biosensors are preferred to be equipment free, easy-to-operate and capable of rapid prototyping. In this work, we developed a pen-on-paper (PoP) strategy based on two custom-made pens, i.e., a wax pen and a conductive-ink pen, to fully write paper-based microfluidic biosensors through directly writing both microfluidic channels and electrodes...

With the use of an ionic liquid as the ultrathermosensitive fluid, a paper thermometer is successfully developed with intrinsic ability of ultrafast response and high stability upon temperature change. The fluidic nature allows the ionic liquid to be easily deposited on paper by pen writing or inkjet printing, affording great promise for large-scale fabrication of low-cost paper sensors. Owing to the advantages of nonvolatilization, excellent continuity and deformability, the thermosensitive ink trapped within the cellulose fibers of paper matrix has no leakage or evaporation at open states, ensuring the excellent stability and repeatability of thermal sensing against arbitrary bending and folding operation...

Many ethicists writing about automated systems (e.g. self-driving cars and autonomous weapons systems) attribute agency to these systems. Not only that; they seemingly attribute an autonomous or independent form of agency to these machines. This leads some ethicists to worry about responsibility-gaps and retribution-gaps in cases where automated systems harm or kill human beings. In this paper, I consider what sorts of agency it makes sense to attribute to most current forms of automated systems, in particular automated cars and military robots...

Images acquired with a long exposure time using a camera embedded on UAVs (Unmanned Aerial Vehicles) exhibit motion blur due to the erratic movements of the UAV. The aim of the present work is to be able to acquire several images with a short exposure time and use an image processing algorithm to produce a stacked image with an equivalent long exposure time. Our method is based on the feature point image registration technique. The algorithm is implemented on the light-weight IGN (Institut national de l'information géographique) camera, which has an IMU (Inertial Measurement Unit) sensor and an SoC (System on Chip)/FPGA (Field-Programmable Gate Array)...

BACKGROUND: Although nursing has been an academic discipline for decades, the infrastructure for nursing research in many countries is still fragile and struggling. Postdoctoral nurses have difficulties developing sustaining careers in nursing research due to lack of career opportunities. Considerable research has been conducted on leadership and mentoring in various areas of nursing. We aimed to systematically review the literature investigating leadership programs and mentoring for postdoctoral nurse researchers, as well as the influence of leadership and mentoring on research productivity, research career development, leadership knowledge and skills, the nurses' health and well-being, staff relationships, work culture and collaboration, salaries and postdoctoral nurses' experiences...

Paul Joyce, Zaid Abdo
In Beisel et al. (2007), a likelihood framework, based on extreme value theory (EVT), was developed for determining the distribution of fitness effects for adaptive mutations. In this paper we extend this framework beyond the extreme distributions and develop a likelihood framework for testing whether or not extreme value theory applies. By making two simple adjustments to the Generalized Pareto Distribution (GPD) we introduce a new simple five parameter probability density function that incorporates nearly every common (continuous) probability model ever used...

Understanding family physical activity (PA) behaviour is essential for designing effective family-based PA interventions. However, effective approaches to capture the perceptions and "lived experiences" of families are not yet well established. The aims of the study were to: (1) demonstrate how a "write, draw, show and tell" (WDST) methodological approach can be appropriate to family-based PA research, and (2) present two distinct family case studies to provide insights into the habitual PA behaviour and experiences of a nuclear and single-parent family...

Hematopoietic stem cell transplantation (HSCT) offers potentially curative therapy for many hematologic and nonhematologic conditions. As a successful outcome of Qatar's National Cancer Strategy, the HSCT program was started in the National Center for Cancer Care and Research (NCCCR) in October 2015. The HSCT program in NCCCR is the only transplant program in Qatar and self-sufficient with all three core components: the stem cell collection facility, the stem cell processing facility, and the clinical program, which are locally available at Hamad Medical Corporation...

Colorimetric sensors based on Sudan- III (1) and Alizarin Red S (2) have been developed for the detection of a trace amount of water in organic solvents such as THF, acetone, acetonitrile and DMSO. The deprotonated (anionic) forms of 1 and 2 such as 1.F and 2.F are re-protonated by using a trace amount of water. Deprotonation of 1 and 2 were obtained by using fluoride anion. Test papers of 1.F and 2.F in organic solvents with and without moisture showed dramatic changes in color. Receptor 1.F exhibits high sensitivity for water in acetone and THF with the detection limit as low as 0...

Catherine Adams, Michael Anders van Manen
In this article, we describe our approach and philosophical methodology of teaching and doing phenomenology. The human science seminar that we offer involves participants in the primary phenomenological literature as well as in a variety of carefully engaged writing exercises. Each seminar participant selects a personal phenomenological project that aims at producing a publishable research paper. We show how the qualitative methodology of hermeneutic phenomenology requires of its practitioner a sensitivity and attitudinal disposition that has to be internalized and that cannot be captured in a procedural or step-by-step program...

BACKGROUND: Statins represent a class of medications widely prescribed to efficiently treat dyslipidemia. These drugs inhibit 3-βhydroxy 3β-methylglutaryl Coenzyme A reductase (HMGR), the rate-limiting enzyme of mevalonate (MVA) pathway. Besides cholesterol, MVA pathway leads to the production of several other compounds, which are essential in the regulation of a plethora of biological activities, including in the central nervous system. For these reasons, statins are able to induce pleiotropic actions, and acquired increased interest as potential and novel modulators in brain processes, especially during pathological conditions...

The UK needs to develop effective policy responses to the spread of tree pathogens and pests. This has been given the political urgency following the media and other commentary associated with the arrival of a disease that causes 'dieback' of European Ash (Fraxinus excelsior) - a tree species with deep cultural associations. In 2014 the UK government published a plant biosecurity strategy and linked to this invested in research to inform policy. This paper reports the findings of a survey of informed UK publics on the acceptability of various potential strategies to deal with ash dieback, including "no action"...
