BACKGROUND: Successfully completing a drawing relies on the ability to accurately impose and manipulate spatial frames of reference for the object that is being drawn and for the drawing space. Typically developing (TD) children use cues such as the page boundary as a frame of reference to guide the orientation of drawn lines. Individuals with Williams syndrome (WS) typically produce incohesive drawings; this is proposed to reflect a local processing bias. AIMS: Across two studies, we provide the first investigation of the effect of using a frame of reference when drawing simple lines and shapes in WS and TD groups (matched for non-verbal ability)...

In this study, we report evidence of a novel duplication of <i>Melanocortin receptor 1 (Mc1r)</i> in the cavefish genome. This locus was discovered following the observation of excessive allelic diversity in a ~820 bp fragment of <i>Mc1r</i> amplified via degenerate PCR from a natural population of <i>Astyanax aeneus</i> fish from Guerrero, Mexico. The cavefish genome reveals the presence of two closely related <i>Mc1r</i> open reading frames separated by a 1...

Across 4,151 participants, the authors demonstrate a novel framing effect, attribute matching, whereby matching a salient attribute of a decision frame with that of a decision's options facilitates decision-making. This attribute matching is shown to increase decision confidence and, ultimately, consensus estimates by increasing feelings of metacognitive ease. In Study 1, participants choosing the more attractive of two faces or rejecting the less attractive face reported greater confidence in and perceived consensus around their decision...

To measure the activity of tissue at the microscopic level, laminar optical tomography (LOT), which is a microscopic form of diffuse optical tomography, has been developed. However, obtaining sufficient recording speed to determine rapidly changing dynamic activity remains major challenges. For a high frame rate of the reconstructed data, we here propose a new LOT method using compressed sensing theory, called compressive laminar optical tomography (CLOT), in which novel digital micromirror device-based illumination and data reduction in a single reconstruction are applied...

We developed a handheld optical coherence tomography angiography (OCTA) system using a 100-kHz swept-source laser. The handheld probe weighs 0.4 kg and measures 20.6 × 12.8 × 4.6 cm(3). The system has dedicated features for handheld operation. The probe is equipped with a mini iris camera for easy alignment. Real-time display of the en face OCT and cross-sectional OCT images in the system allows accurately locating the imaging target. Fast automatic focusing was achieved by an electrically tunable lens controlled by a golden-section search algorithm...

We formed a database gathering the wavefront aberrations of 50 healthy eyes measured with an original custom-built Shack-Hartmann aberrometer at a temporal frequency of 236 Hz, with 22 lenslets across a 7-mm diameter pupil, for a duration of 20 s. With this database, we draw statistics on the spatial and temporal behavior of the dynamic aberrations of the eye. Dynamic aberrations were studied on a 5-mm diameter pupil and on a 3.4 s sequence between blinks. We noted that, on average, temporal wavefront variance exhibits a n(-2) power-law with radial order n and temporal spectra follow a f(-1...

Leonard J Appleman, Jodi K Maranchie
Surgical resection for metastatic renal cell carcinoma (RCC) was first described several decades ago, but the appropriate role for surgery in coordinated multidisciplinary care has not been well-defined. The explosive development of new therapies for advanced RCC over the past 10 years has improved the outlook for patients, and there is now renewed interest in surgical metastasectomy for selected patients with metastatic RCC, moving away from the conventional dichotomy between surgery for local disease and systemic therapy for metastatic disease...

In molluscs, muscle contraction is triggered by a direct binding of Ca(2+) to myosin. The myosin essential light chain (MELC) provides the Ca(2+) binding site and is of importance for motor function and regulation. In this study, the complete cDNA sequence of MELC gene of the Pacific oyster, Crassostrea gigas, was obtained, and the expression profiles were performed in different tissues and different embryo-larval development stages. The results showed that the full length of C. gigas MELC (CgMELC) cDNA was 659 bp, containing a 5'-untranslated region of 73 bp, a 3'-untranslated region of 112 bp...

Intracranial aneurysms are common and, on a population-based perspective, are a major cause of morbidity and mortality as a result of mass effect or rupture. Cerebral angiography is the primary technique used for the diagnosis of cerebral aneurysms, and the imaging data have additional utility for planning medical, endovascular, or surgical treatments. An extremely rare periprocedural complication of cerebral angiography is rupture of the aneurysm, either as a chance phenomenon or as a result of some physiologic change or mechanical effect...

The infectivity of equine herpesvirus (EHV)-9 has been studied in different animal models including immunocompromised animals. The current study focused on the infectivity of EHV-9 in different mouse strains (C3H, C57BL, DBA, BALB/c-nu/nu, BALB/c and ICR) by intranasal inoculation of 2 × 10(6) plaque forming units (PFU). Various organs, including head and lungs, were collected 7 days post infection (dpi) to investigate microscopical lesions and the distribution of EHV-9 antigen. Immunopositivity of tissue sections was scored using ImageJ software...

Tarini Singh, Christian Frings, Birte Moeller
Binding theories assume that a stimulus and the response made to it are bound together in an event file (Hommel et al., Behav Brain Sci 24(05):849-937, 2001). Such bindings can occur even after single encounters. If the stimulus or parts of its features are repeated within the time frame in which the event file is still intact, the previously integrated response is retrieved. Stimulus-response binding can exist at a perceptual, conceptual or a response selection level (Henson et al., Trends Cogn Sci 18(7):376-384, 2014)...

As connected autonomous vehicles (CAVs) enter the fleet, there will be a long period when these vehicles will have to interact with human drivers. One of the challenges for CAVs is that human drivers do not communicate their decisions well. Fortunately, the kinematic behavior of a human-driven vehicle may be a good predictor of driver intent within a short time frame. We analyzed the kinematic time series data (e.g., speed) for a set of drivers making left turns at intersections to predict whether the driver would stop before executing the turn...

#17
Colin J Palmer, Colin W G Clifford
The primate visual system contains specialised neural mechanisms for encoding the direction of others' gaze. A foundational question that we can ask in this domain concerns the frame of reference in which another person's gaze is represented. Electrophysiological recordings in macaque monkeys suggest that direction of gaze might be encoded relative to the observer (i.e., in a first person reference frame) or relative to the head or body of the stimulus (i.e., in a second person reference frame). Here we use sensory adaptation to gaze direction as a psychophysical tool to probe how this property of the environment is represented in the human visual system...

P Vinoth, P Sankar
An in-silico system to encode structure, bonding and properties of coordination complexes is developed. The encoding is achieved through a semantic XML markup frame. Composition of the coordination complexes is captured in terms of central atom and ligands. Structural information of central atom is detailed in terms of electron status of valence electron orbitals. The ligands are encoded with specific reference to the electron environment of ligand centre atoms. Behaviour of ligands to form low or high spin complexes is accomplished by assigning a Ligand Centre Value to every ligand based on the electronic environment of ligand centre atom...

The quality of life and individual well-being are universally recognised as key factors in disease prevention. In particular, lifestyle interventions are effective tools for reducing the risk and incidence of major illnesses, such as cardiovascular diseases and metabolic disorders. On the other hand, patient role is progressively shifting from being a passive recipient of care towards being a co-producer of her/his health. In this frame, novel devices and systems able to help individuals in self-evaluation are expected to play a crucial role...

Jia Jin, Wuke Zhang, Mingliang Chen
Due to the limitations of the human ability to process information, e-consumers' decisions are likely to be influenced by various cognitive biases, such as the attribute framing effect. This effect has been well studied by numerous scholars; however, the associated underlying neural mechanisms with a critical temporal resolution have not been revealed. Thus, this study applies the measurement of event-related potentials (ERPs) to directly examine the role of attribute framing in information processing and decision-making in online shopping...
