Asymmetrical interference between number and item size perception provides evidence for a domain specific impairment in dyscalculia.

PLoS One 2018 14;13(12):e0209256. Epub 2018 Dec 14.

Cognitive Neuroimaging Unit, CEA DRF/I2BM, INSERM, Université Paris-Sud, Université Paris-Saclay, NeuroSpin Center, Gif-sur-Yvette, France.

Dyscalculia, a specific learning disability that impacts arithmetical skills, has previously been associated to a deficit in the precision of the system that estimates the approximate number of objects in visual scenes (the so called 'number sense' system). However, because in tasks involving numerosity comparisons dyscalculics' judgements appears disproportionally affected by continuous quantitative dimensions (such as the size of the items), an alternative view linked dyscalculia to a domain-general difficulty in inhibiting task-irrelevant responses. To arbitrate between these views, we evaluated the degree of reciprocal interference between numerical and non-numerical quantitative dimensions in adult dyscalculics and matched controls. Read More

The relation of culture, socio-economics, and friendship to music preferences: A large-scale, cross-country study.

PLoS One 2018 14;13(12):e0208186. Epub 2018 Dec 14.

Institute of Computational Perception, Johannes Kepler University Linz, Linz, Austria.

Music listening is an inherently cultural behavior, which may be shaped by users' backgrounds and contextual characteristics. Due to geographical, socio-economic, linguistic, and cultural factors as well as friendship networks, users in different countries may have different music preferences. Investigating cultural-socio-economic factors that might be associated with between-country differences in music preferences can facilitate music information retrieval, contribute to the prediction of users' music preferences, and improve music recommendation in cross-country contexts.

Medical Services, Ralph H. Johnson VA Medical Center, Charleston, SC, USA.

We read the recent article by Yoowannakul et al. [1] with great interest but we are at disagreement with some of their approach and conclusions. The Authors "found no association between overhydration and right ventricular volumes" using bioimpedance with the cardiac MRI, while they also "found that NT pro-BNP …was associated with left sided cardiac chamber sizes… but not right ventricular dimensions, which would suggest that NT-pro-BNP does not reflect plasma volume".

Age but no sex effects on subareas of the amygdala.

Hum Brain Mapp 2018 Dec 13. Epub 2018 Dec 13.

School of Psychology, University of Auckland, Auckland, New Zealand.

The amygdala, an anatomical composite of several nuclei that have been grouped anatomically and functionally into three major subareas, has been reported to decrease in size with increasing age and to differ in size between male and female brains. However, findings are rather inconsistent across existing studies, possibly reflecting differences in the cohorts examined or the approaches chosen to define and measure the dimensions of the amygdala. Here, we investigated possible effects of age and sex on the amygdala as well as age-by-sex interactions in 100 healthy subjects (50 men/50 women) aged 18-69 years. Read More

Polyelemental Nanolithography via Plasma Ion Bombardment: From Fabrication to Superior H Sensing Application.

Adv Mater 2018 Dec 14:e1805343. Epub 2018 Dec 14.

Department of Chemical and Biomolecular Engineering (BK-21 Plus), Korea Advanced Institute of Science and Technology (KAIST), Yuseong-gu, Daejeon, 34141, Republic of Korea.

The development of complex nanostructures containing a homo- and heteromixture of two or more metals is a considerable challenge in nanotechnology. However, previous approaches are considerably limited to the number of combinations of metals depending on the compatibility of elements, and to the complex shape control of the nanostructure. In this study, a significant step is taken toward resolving these limitations via the utilization of a low-energy argon-ion bombardment. Read More

DENTAL SIGNATURES FOR EXUDATIVORY IN LIVING PRIMATES, WITH COMPARISONS TO OTHER GOUGING MAMMALS.

Anat Rec (Hoboken) 2018 Dec 12. Epub 2018 Dec 12.

Dept. of Anthropology, University of Toronto Scarborough, Toronto, CANADA.

Exudativory, the consumption of gums, is an obligate or a facultative dietary niche for some primates and marsupials. Exudativory has been cited as a dietary niche that may have been present in early primates, so finding a dental signature for exudativory is highly desirable. The present study combines exudativorous lorisoids (galagos and lorises) into one sample to compare to closely related, non-exudativorous lorisoids to search for a consistent dental signature of exudativory.

Beijing National Laboratory for Molecular Sciences (BNLMS), CAS Research/Education Center for Excellence in Molecular Sciences, Institute of Chemistry, Chinese Academy of Sciences, Beijing, 100190, P. R. China.

The structural and interfacial stabilities of metal oxides (MOs) are key issues while facing the volumetric variation and intensive interfacial polarization in electrochemical applications, including lithium-ion batteries (LIBs), supercapacitors, and catalysts. The growth of a seamless all-carbon interfacial layer on MOs with complex dimensions is not only a scientific problem, but also a practical challenge in these fields. Here, the growth of graphdiyne under ultramild condition is successfully implemented in situ for coating MOs of complex dimensions. Read More

Getting into shape: Limb bone strength in perinatal Lemur catta and Propithecus coquereli.

Anat Rec (Hoboken) 2018 Dec 8. Epub 2018 Dec 8.

School of Physical Therapy, Slippery Rock University, Slippery Rock, PA, 16057.

Functional studies of skeletal anatomy are predicated on the fundamental assumption that form will follow function. For instance, previous studies have shown that the femora of specialized leaping primates are more robust than those of more generalized primate quadrupeds. Are such differences solely a plastic response to differential loading patterns during postnatal life, or might they also reflect more canalized developmental mechanisms present at birth? Here, we show that perinatal Lemur catta, an arboreal/terrestrial quadruped, have absolutely and relatively weaker femora than perinatal Propithecus coquereli, a closely-related species specialized for vertical clinging and leaping (a highly unusual locomotor mode in which the hindlimbs are used to launch the animal between vertical tree trunks).

'I'd like to report a suspicious looking tree': Public concern, public attention and the nature of reporting about ash dieback in the United Kingdom.

Public Underst Sci 2018 Dec 14:963662518814369. Epub 2018 Dec 14.

Imperial College London, UK.

'Public concern', a ubiquitous notion used in descriptive and explanatory modes by policy makers, academics and the media, is often presented as axiomatic. However, the variability with which it is deployed in different contexts, for example, as justification for policy attention or having equivalence with what is considered 'newsworthy', belies this status. This article presents an empirical analysis of emails and phone calls from the UK public to UK government agencies, reporting suspected cases of ash dieback disease - a tree health issue which attracted intense media and policy attention in the United Kingdom in 2012.

Reduced empathy and alexithymic traits are common across the autism spectrum, but it is unknown whether this is also true for intellectually advanced adults with autism spectrum disorder. The aim of this study was to examine whether college students with autism spectrum disorder experience difficulties with empathy and alexithymia, and whether this is associated with their cognitive levels of executive functioning. In total, 53 college students with autism spectrum disorder were compared to a gender-matched group of 29 neurotypical students on cognitive and affective dimensions of empathy and alexithymia.

Authors:
D A Pesin

Phys Rev Lett 2018 Nov;121(22):226601

Department of Physics and Astronomy, University of Utah, Salt Lake City, Utah 84112, USA.

We show that electrons undergoing a two-particle collision in a crystal experience a coordinate shift that depends on their single-particle Bloch wave functions and derive a gauge-invariant expression for such a shift, valid for arbitrary band structures and arbitrary two-particle interaction potentials. As an application of the theory, we consider two-particle coordinate shifts for Weyl fermions in space of three spatial dimensions. We demonstrate that such shifts in general contribute to the anomalous Hall conductivity of a clean electron liquid. Read More

Center for Language and Literature, Lund University, Lund, Sweden.

We report a series of 22 experiments in which the implicit associations test (IAT) was used to investigate cross-modal correspondences between visual (luminance, hue [R-G, B-Y], saturation) and acoustic (loudness, pitch, formants [F1, F2], spectral centroid, trill) dimensions. Colors were sampled from the perceptually accurate CIE-Lab space, and the complex, vowel-like sounds were created with a formant synthesizer capable of separately manipulating individual acoustic properties. In line with previous reports, the loudness and pitch of acoustic stimuli were associated with both luminance and saturation of the presented colors. Read More

The effect of flexible joint-like elements on the adhesive performance of nature-inspired bent mushroom-like fibers.

Beilstein J Nanotechnol 2018 19;9:2893-2905. Epub 2018 Nov 19.

Mechanical Engineering, Texas Tech University, Lubbock, TX 79409-1021, USA.

Many organisms rely on densely packed, tilted and curved fibers of various dimensions to attach to surfaces. While the high elastic modulus of these fibers enables an extremely large number of fibers per unit area, where each fiber stands freely without sticking to its neighbors, the tilt/curvature provides them with the compliance and the directional adhesion properties to attach strongly and efficiently to a surface. Recent studies have revealed that many of such organisms also feature materials with a graded elastic modulus that is tailored towards improving the contact area without sacrificing the fiber density.

The Over-Extended Mind? Pink Noise and the Ethics of Interaction-Dominant Systems.

Nanoethics 2018 1;12(3):269-281. Epub 2018 Nov 1.

4Department of Health and Social Sciences, UWE, Bristol, Coldharbour Lane, Bristol, BS16 1QY UK.

There is a growing recognition within cognitive enhancement and neuroethics debates of the need for greater emphasis on cognitive artefacts. This paper aims to contribute to this broadening and expansion of the cognitive-enhancement and neuroethics debates by focusing on a particular form of relation or coupling between humans and cognitive artefacts: interaction-dominance. We argue that interaction-dominance as an emergent property of some human-cognitive artefact relations has important implications for understanding the attribution and distribution of causal and other forms of responsibility as well as agency relating to the actions of human-cognitive artefact couplings.

Linking Cognitive Measures of Response Inhibition and Reward Sensitivity to Trait Impulsivity.

Front Psychol 2018 28;9:2306. Epub 2018 Nov 28.

Department of Psychiatry, Cumming School of Medicine, University of Calgary, Calgary, AB, Canada.

Impulsivity is regarded as a multifaceted construct that comprises two dimensions: rapid-response impulsivity and reward-delay impulsivity. It is unclear, however, which aspects of trait impulsivity, as assessed by self-report measures are related to rapid-response impulsivity and/or to reward-delay impulsivity, as different results have been reported in studies using both self-report and cognitive measures. This study aimed to directly relate self-report measures of impulsivity to cognitive measures of impulsivity in individuals at low- or high-levels on two impulsivity dimensions, specifically rapid-response impulsivity and reward-delay impulsivity.

Sport-specific differences in the left ventricle (LV) of land-based athletes have been observed; however, comparisons to water-based athletes are sparse. The purpose of this study was to examine differences in LV structure and function in elite swimmers and runners. Sixteen elite swimmers [23 (2) years, 81% male, 69% white] and 16 age, sex, and race matched elite runners participated in the study. Read More

3D nanofabrication by volumetric deposition and controlled shrinkage of patterned scaffolds.

Science 2018 Dec;362(6420):1281-1285

MIT Media Lab, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.

Lithographic nanofabrication is often limited to successive fabrication of two-dimensional (2D) layers. We present a strategy for the direct assembly of 3D nanomaterials consisting of metals, semiconductors, and biomolecules arranged in virtually any 3D geometry. We used hydrogels as scaffolds for volumetric deposition of materials at defined points in space. Read More

Cancer Epidemiology Department, Moffitt Cancer Center & Research Institute, 12902 Bruce B Downs Blvd, Mail Stop: MRC Can/Cont, Tampa, FL 33612. Electronic address:

Rationale And Objectives: Mammographic density is an important risk factor for breast cancer, but translation to the clinic requires assurance that prior work based on mammography is applicable to current technologies. The purpose of this work is to evaluate whether a calibration methodology developed previously produces breast density metrics predictive of breast cancer risk when applied to a case-control study.

Materials And Methods: A matched case control study (n = 319 pairs) was used to evaluate two calibrated measures of breast density. Read More
