Q Fu, D H Wang, L Xu, G Yuan
Nonlinear oscillators are usually utilized by bionic scientists for establishing central pattern generator models for imitating rhythmic motions by bionic scientists. In the natural word, many rhythmic motions possess asymmetric time ratios, which means that the forward and the backward motions of an oscillating process sustain different times within one period. In order to model rhythmic motions with asymmetric time ratios, nonlinear oscillators with asymmetric forward and backward trajectories within one period should be studied...

Dror Dotan, Naama Friedmann
We propose a detailed cognitive model of multi-digit number reading. The model postulates separate processes for visual analysis of the digit string and for oral production of the verbal number. Within visual analysis, separate sub-processes encode the digit identities and the digit order, and additional sub-processes encode the number's decimal structure: its length, the positions of 0, and the way it is parsed into triplets (e.g., 314987 → 314,987). Verbal production consists of a process that generates the verbal structure of the number, and another process that retrieves the phonological forms of each number word...

Introduction: Patients with obsessive compulsive disorder (OCD) have impaired cognitive functions, including attention, verbal and visual memory, and visual-spatial abilities as well as executive function But some studies did not show any disturbance in executive function of patients with OCD. To date, only few studies have been conducted on neuropsychological functioning of patients with panic disorder (PD). There are limited studies to reach a definite conclusion on executive functions of patients with OCD and those with PD...

We present here emoFinder ( http://usc.es/pcc/emofinder ), a Web-based search engine for Spanish word properties taken from different normative databases. The tool incorporates several subjective word properties for 16,375 distinct words. Although it focuses particularly on normative ratings for emotional dimensions (e.g., valence and arousal) and discrete emotional categories (fear, disgust, anger, happiness, and sadness), it also makes available ratings for other word properties that are known to affect word processing (e...

Across 3 studies we show that emotion words support the acquisition of conceptual knowledge for emotional facial actions that then biases subsequent perceptual memory for later emotional facial actions. In all studies, participants first associated emotional facial actions with a word during a learning phase or completed a control task. In a target phase, participants studied slightly different category exemplars. During a final test phase, participants identified which face the individual had been making during the target phase (i...

L C Pardo, S E McLain
In his comment on a recent publication by us, G. Graziano claims that solubility differences of indole in methanol and water can be rationalized by the reversible work needed to create a cavity in the solvent of the size of the solute, in this case indole. This quantity, he argues, is closely related to the solvent accessible surface area, which is greater for methanol compared with water, thus making indole more soluble in the former solvent. G. Graziano asserts that it is this property which is responsible for the large difference between the solubilities of indole in methanol and water...

INTRODUCTION: The SAGE Working Group on Vaccine Hesitancy developed a vaccine hesitancy measure, the Vaccine Hesitancy Scale (VHS). This scale has the potential to aid in the advancement of research and immunization policy but has not yet been psychometrically evaluated. METHODS: Using a cross-sectional design, we collected self-reported survey data from a large national sample of Canadian parents from August to September 2016. An online questionnaire was completed in English or French...

R Kenny, M Reed, A Subramanian
BACKGROUND: Prophylactic or 'risk-reducing' mastectomy refers to the procedure of completely removing a healthy breast in order to reduce the risk of developing breast cancer. This may be bilateral or may be performed to the contralateral breast as part of the treatment of a proven breast cancer. The rate of this procedure being performed has been shown to be increasing over the last two decades. Recent guidance for Breast clinicians has been issued over the last 12 months by both The Association of Breast Surgery of Great Britain and Ireland (ABSGBI) and the American Society of Breast Surgeons (ASBrS)...

In neuroimaging, functional magnetic resonance imaging (fMRI) measures the blood-oxygenation-level dependent (BOLD) signal in the brain. The degree of correlation of the BOLD signal in spatially independent regions of the brain defines the functional connectivity of those regions. During a cognitive fMRI task, a psychophysiological interaction (PPI) analysis can be used to examine changes in the functional connectivity during specific contexts defined by the cognitive task. An example of such a task is one that engages the memory system, asking participants to learn pairs of unrelated words (encoding) and recall the second word in a pair when presented with the first word (retrieval)...

Sofoklis Kakouros, Nelli Salminen, Okko Räsänen
Perceptual prominence of linguistic units such as words has been earlier connected to the concepts of predictability and attentional orientation. One hypothesis is that low-probability prosodic or lexical content is perceived as prominent due to the surprisal and high information value associated with the stimulus. However, the existing behavioral studies have used stimulus manipulations that follow or violate typical linguistic patterns present in the listeners' native language, i.e., assuming that the listeners have already established a model for acceptable prosodic patterns in the language...

This paper presents a novel approach to recognize a scene presented in an image with specific application to scene classification in field sports video. We propose different variants of the algorithm ranging from bags of visual words to the simplified real-time implementation, that takes only the most important areas of similar colour into account. All the variants feature similar accuracy which is comparable to very well-known image indexing techniques like SIFT or HoGs. For the comparison purposes, we also developed a specific database which is now available online...

A single word, Epigenetics, underlies one exciting subject in today's Science, with different sides and with interactions with philosophy. The apparent trivial description includes everything in between genotype and phenotype that occurs for a given unique DNA sequence/genome. This Perspective article first presents an historical overview and the reasons for the lack of consensus in the field, which derives from different interpretations of the diverse operative definitions of Epigenetics. In an attempt to reconcile the different views, we propose a novel concept, the "cytocrin system...

BACKGROUND: Children with developmental language disorder (DLD) frequently have difficulties with word learning and understanding vocabulary. For these children, this can significantly impact on social interactions, daily activities and academic progress. Although there is literature providing a rationale for targeting word learning in such children, there is little evidence for the effectiveness of specific interventions in this area for children with identified DLD. AIMS: To establish whether direct one-to-one intervention for children with DLD over 9 years of age leads to improved abilities to identify, comprehend, define, and use nouns and verbs targeted in intervention as compared with non-targeted control items and whether or not the participants' rating of their own knowledge of the words changes with intervention...

Emma V Ward
Older adults often show greater implicit/unconscious memory than young adults for incidental information that was task-irrelevant during its acquisition. Shallow/perceptual encoding by older adults may boost performance on implicit tasks that reinstate this type of processing, whereas deeper/conceptual encoding by young adults may support greater explicit/conscious memory. To test this, young and older participants were exposed to incidental words in a text color identification task before the trial-by-trial capture of priming and recognition...

Tropical mountains are usually characterized by a vertically-arranged sequence of ecological belts, which, in contrast to temperate habitats, have remained relatively stable in space across the Quaternary. Such long-lasting patterning of habitats makes them ideal to test the role of environmental pressure in driving ecological and evolutionary processes. Using Sumatran freshwater mayfly communities, we test whether elevation, rather than other spatial factors (i.e. volcanoes, watersheds) structures both species within communities and genes within species...

Executive function (EF) includes a range of decision-making and higher-order thinking processes. Although the genetic basis of EF has been studied and reviewed, epigenetic factors that influence EF are an emerging field of interest; here, we summarize the current research. Work relating to different word combinations of 'Executive Function' and 'Epigenetic' was identified through three academic search directories. Inclusion criteria were human populations, EF testing, epigenetic testing or genotyping related to epigenetic regulation...

In this article, I do not intend to present the many and well-known treatments for relieving pain and distress symptoms of the physical body, damaged by terminal diseases, such as cancer, AIDS, multiple sclerosis. In this article, I'd rather focus my attention on clinical hypnosis for subjects who, freed from physical pain, thanks to palliative care, are open to receiving comfort and support for their psychological and spiritual suffering. The intent of this article is to express how clinical hypnosis can harmoniously integrate psychological and spiritual aspects so that the terminal patient can make peace with his/her past, with the people who have hurt him/her, and with the people who will suffer because of his/her death...

BACKGROUND: Carpal tunnel syndrome (CTS) is the most common peripheral neuropathy, characterized by the presence of many sensory and motor abnormalities. In the physiotherapy of patients with CTS, neurodynamic tech-niques are very common, while the scientific literature does not show clear evidence of beneficial effects obtained by using these techniques. Therefore, the aim of this work was to critically evaluate the use of neurodynamic techniques in the conservative treatment of CTS...
