The ubiquity and mobility of contemporary computing devices has enabled users to consume content, anytime, anywhere. Yet, when we need to create content, touch input is far from perfect. When coupled with touch input, the stylus should enable users to simultaneously ink, manipulate the page, and switch between tools with ease, so why has the stylus yet to achieve universal adoption? Michelle Annett's thesis sought to understand the usability barriers and tensions that have prevented stylus input from gaining traction and reaching widespread adoption...

OBJECTIVES: The current study sought to characterize changes in salivary oxytocin (OT) secretion patterns across the breastfeeding cycle, and to evaluate whether breastfeeding has a positive effect on mood disturbances related to postpartum depression, via endogenous OT release. MATERIALS AND METHODS: Twenty-four primiparous mothers who delivered vaginally at term and were exclusively breastfeeding were examined 4-5 days postpartum. Salivary OT was measured using enzyme immunoassays at 30 minutes before breastfeeding (baseline), during breastfeeding (feeding), and 30 minutes after completing breastfeeding (postfeeding)...

Kinked silicon (Si) nanowires (NWs) have many special properties that make them attractive for a number of applications, such as microfluidics devices, microelectronic devices, and biosensors. However, fabricating NWs with controlled 3D geometry has been challenging. In this work, a novel method called alternating metal-assisted chemical etching, or alternating MACE, is reported for the fabrication of kinked Si NWs with controlled 3D geometry. By the use of multiple etchants with carefully selected composition, one can control the number of kinks, their locations, and their angles by controlling the number of etchant alternations and the time in each etchant...

Nanosphere lithography, an inexpensive and high throughput technique capable of producing nanostructure (below 100 nm feature size) arrays, relies on the formation of a monolayer of self-assembled nanospheres, followed by custom-etching to produce nanometre size features on large-area substrates. A theoretical model underpinning the self-ordering process by centrifugation is proposed to describe the interplay between the spin speed and solution concentration. The model describes the deposition of a dense and uniform monolayer by the implicit contribution of gravity, centrifugal force and surface tension, which can be accounted for using only the spin speed and the solid/liquid volume ratio...

OBJECTIVE: We describe client-therapist relational narratives collected in relationship anecdotes paradigm (RAP) interviews during psychotherapy and the application of the core conflictual relationship theme (CCRT) method. Changes in clients' and therapists' CCRT in relation to each other are examined and associations between their CCRTs and self-reported ruptures and repairs are explored. METHOD: Sixty-seven clients and 27 therapists underwent RAP interviews and completed self-report rupture and repair items at early, middle, and late psychodynamic psychotherapy...

This article draws on the free-text commentaries from trans-Tasman studies that used the MISSCARE questionnaire to explore the reasons why nurses miss care. In this paper, we examine the idea that nurses perpetuate a self-effacing approach to care, at the expense of patient care and professional accountability, using what they describe as the art of nursing to frame their claims of both nursing care and missed nursing care. We use historical dialogue alongside a paradigmatic analysis to examine why nurses allow themselves to continue working within settings that put their professional/personal selves aside in an attempt to deliver care within constraints that make completing care an impossible task...

Phospholipids and their partial hydrolysates, namely lysophospholipids (LPLs), have been widely used in food, pharmaceutical, and cosmetic products as highly efficient emulsifiers. This study was conducted to produce docosahexaenoic acid (DHA)-esterified LPLs by enzymatic modification of phospholipids obtained from the head of autumn chum salmon (Oncorhynchus keta). The emulsifying properties of the obtained LPLs were also evaluated. Two different types of substrates of salmon head phospholipids were prepared via silica gel and cold acetone precipitation...

Mangroves in hypersaline coastal habitats are under constant high xylem tension and face great risk of hydraulic dysfunction. To investigate the relationships between functional traits and salt management, we measured 20 hydraulic and photosynthetic traits in four salt-adapted (SA) and two non-SA (NSA) mangrove tree species in south China. The SA species included two salt secretors (SSs), Avicennia marina (Forsskål) Vierhapper and Aegiceras corniculatum (L.) Blanco and two salt excluders (SEs), Bruguiera gymnorrhiza (L...

Background Different advantages of virtually planned and guided mandibular reconstructions have been described. Functional analyses and comparisons with conventionally reconstructed patients. Methods We retrospectively analyzed 30 cases of mandibular reconstructions that involved virtually planned or conventional microvascular, fibular free flaps that occurred between April 2011 and December 2014 at a single center. The results were also compared with a healthy cohort of 30 participants. Axiographic measurements were performed postoperatively, and uni- and multivariate regressions analyses were performed to determine the association between possible predictor variables on functional outcome...

Preoxygenation before anesthetic induction and tracheal intubation is a widely accepted maneuver, designed to increase the body oxygen stores and thereby delay the onset of arterial hemoglobin desaturation during apnea. Because difficulties with ventilation and intubation are unpredictable, the need for preoxygenation is desirable in all patients. During emergence from anesthesia, residual effects of anesthetics and inadequate reversal of neuromuscular blockade can lead to hypoventilation, hypoxemia, and loss of airway patency...

Acrylic latexes are valuable waterborne materials used in controlled-release fertilizers. Controlled-release urea coated with these latexes release a large amount of nutrients, making it difficult to meet the requirement of plants. Herein, FeⅢ-Tannic Acid (TA) complexes, which were blended with acrylic latex and subsequently reassembled capsules on a surface of polyacrylate particles. These complexes remarkably retarded the release of urea (the preliminary solubility was decreased from 22.3% to 0.8%) via decreasing the coating tackiness (Tg was increased from 4...

OBJECTIVE: Many patients are admitted to the ICU at or near the end of their lives. Consequently, the increasingly common debate regarding physician-assisted suicide and euthanasia holds implications for the practice of critical care medicine. The objective of this article is to explore core ethical issues related to physician-assisted suicide and euthanasia from the perspective of healthcare professionals and ethicists on both sides of the debate. SYNTHESIS: We identified four issues highlighting the key areas of ethical tension central to evaluating physician-assisted suicide and euthanasia in medical practice: 1) the benefit or harm of death itself, 2) the relationship between physician-assisted suicide and euthanasia and withholding or withdrawing life support, 3) the morality of a physician deliberately causing death, and 4) the management of conscientious objection related to physician-assisted suicide and euthanasia in the critical care setting...

Our bodies are in constant motion and so are the neurons that invade each tissue. Motion-induced neuron deformation and damage are associated with several neurodegenerative conditions. Here, we investigated the question of how the neuronal cytoskeleton protects axons and dendrites from mechanical stress, exploiting mutations in UNC-70 β-spectrin, PTL-1 tau/MAP2-like and MEC-7 β-tubulin proteins in Caenorhabditis elegans. We found that mechanical stress induces supercoils and plectonemes in the sensory axons of spectrin and tau double mutants...

Silicon-based two-dimensional (2D) materials are uniquely suited for integration in Si-based electronics. Silicene, an analog of graphene, was recently fabricated on several substrates and was used to make a field-effect transistor. Here, we report that, when Ru(0001) is used as a substrate, a range of distinct monolayer silicon structures forms, evolving towards silicene with increasing Si coverage. Low Si coverage produces a herringbone structure, a hitherto undiscovered 2D phase of silicon. With increasing Si coverage, herringbone elbows evolve into silicene-like honeycomb stripes under tension, resulting in a herringbone-honeycomb 2D superlattice...

Skin injuries are the most common type of injuries occurring in day-to-day life. A skin injury usually manifests itself in the form of a wound or a cut. While a shallow wound may heal by itself within a short time, deep wounds require surgical interventions such as suturing for timely healing. To date, suturing practices are based on a surgeon's experience and may vary widely from one situation to another. Understanding the mechanics of wound closure and suturing of the skin is crucial to improve clinical suturing practices and also to plan automated robotic surgeries...

PURPOSE: Lumbar incisional hernias (LIH) are a rare wall defect, whose surgical management is challenging because no recommendation exists. Moreover, LIH are frequently associated with flank bulging which should be taken into account during LIH surgical repair. We aimed to describe a cohort of patients operated on for LIH using a homogeneous surgical technique and to report surgical outcomes. METHODS: The records of all consecutive patients operated on in a specialized surgical center between January 2009 and January 2015 were retrospectively reviewed...

Double seismic zones are two-layered distributions of intermediate-depth earthquakes that provide insight into the thermomechanical state of subducting slabs. We present new precise hypocenters of intermediate-depth earthquakes in the Tonga subduction zone obtained using data from local island-based, ocean-bottom, and global seismographs. The results show a downdip compressional upper plane and a downdip tensional lower plane with a separation of about 30 km. The double seismic zone in Tonga extends to a depth of about 300 km, deeper than in any other subduction system...

Domain migration is observed on the surface of ternary giant unilamellar vesicles held in a temperature gradient in conditions where they exhibit coexistence of two liquid phases. The migration localizes domains to the hot side of the vesicle, regardless of whether the domain is composed of the more ordered or disordered phase and regardless of the proximity to chamber boundaries. The distribution of domains is explored for domains that coarsen and for those held apart due to long-range repulsions. After considering several potential mechanisms for the migration, including the temperature preferences for each lipid, the favored curvature for each phase, and the thermophoretic flow around the vesicle, we show that observations are consistent with the general process of minimizing the system's line tension energy, because of the lowering of line interface energy closer to mixing...
