AbstractBackground:Borderline personality disorder (BPD) is a chronic condition with a strong impact on patients’ affective, cognitive and social functioning. Neuroimaging techniques offer invaluable tools to understand the biological substrate of the disease. We aimed to investigate gray matter alterations over the whole cortex in a group of Borderline Personality Disorder (BPD) patients compared to healthy controls (HC).Methods:Magnetic resonance-based cortical pattern matching was used to assess cortical gray matter density (GMD) in 26 BPD patients and in their age- and sex-matched HC (age: 38 ± 11; females: 16, 61%).Results:BPD patients showed widespread lower cortical GMD compared to HC (4% difference) with peaks of lower density located in the dorsal frontal cortex, in the orbitofrontal cortex, the anterior and posterior cingulate, the right parietal lobe, the temporal lobe (medial temporal cortex and fusiform gyrus) and in the visual cortex (P < 0.005). Our BPD subjects displayed a symmetric distribution of anomalies in the dorsal aspect of the cortical mantle, but a wider involvement of the left hemisphere in the mesial aspect in terms of lower density. A few restricted regions of higher density were detected in the right hemisphere. All regions remained significant after correction for multiple comparisons via permutation testing.Conclusions:BPD patients feature specific morphology of the cerebral structures involved in cognitive and emotional processing and social cognition/mentalization, consistent with clinical and functional data.

AbstractA 59‐year‐old woman with hypertrophic obstructive cardiomyopathy was admitted to our institution with worsening heart failure. She developed mechanical intracardiac hemolysis due to left ventricular outflow tract (LVOT) obstruction. Despite surgical myectomy, the LVOT pressure gradient (PG) remained high and hemolytic anemia recurred. A dual‐chamber implantable cardioverter defibrillator was then implanted, which decreased the LVOT‐PG and improved hemolysis.
Soft suspensions: inertia cooperates with flexibility
Authors: Misbah Chaouqi 
Published: January 2015

AbstractCross-streamline migration of soft particles in suspensions is essential for cell and DNA sorting, blood flow, polymer processing and so on. Pioneering work by Poiseuille on blood flow in vivo revealed an erythrocyte-free layer close to blood vessel walls. The formation of this layer is related to a viscous lift force caused by cell deformation that pushes cells towards the centre of blood capillaries. This lift force has in this case a strong impact on blood flow. In contrast, rigid spherical particles migrate from the centre towards the periphery, owing to inertia (the Segré–Silberberg effect). An important open issue is to elucidate the interplay between particle deformation and inertia. By using a capsule suspension model, Krueger, Kaoui & Harting (J. Fluid Mech., 2014, vol. 751, pp. 725–745) discovered that capsule flexibility can suppress the Segré–Silberberg effect and inertia promotes overall flow efficiency thanks to a strong inertial flow focusing effect.
Osteology and taxonomy of Mosasaurus conodon Cope 1881 from the Late Cretaceous of North America
Authors: Ikejiri T. , Lucas S.G. 
Published: January 2015

AbstractTwo well-preserved skeletons of Mosasaurus conodon Cope 1881 (Squamata, Mosasaurinae) from the Pierre Shale (late Campanian) of Colorado and the Bearpaw Shale (Late Campanian to Early Maastrichtian) of Montana are described. The two specimens are important because they provide new osteological information, especially on the skull (including jaws with teeth) and forelimbs, whereas those elements are largely missing in the holotype (AMNH 1380) of M. conodon. Morphological comparisons of the holotype with the two new specimens allow us to emend the diagnosis of the species in the genus Mosasaurus, primarily using tooth and forelimb morphologies. Teeth of M. conodon are unique in their combination of having a slender, gently recurved overall shape (similar to Clidastes) with no serration on the developed carinae (less developed in Clidastes). The tooth count of M. conodon tends to be low (14–15 in the maxilla, 16 in the dentary and eight in the pterygoid, respectively) when compared to other species, such as Mosasaurus lemonnieri, Mosasaurus missouriensis and Mosasaurus hoffmanni–Mosasaurus maximus. The forelimb is short in the species, characterised by a much lower number of the manual digital formula, 4(+1?)–4(+2?)–4(+1?)–4(+1)–2 than other species of Mosasaurus. The forelimb bones are generally robust, especially the box-shaped humerus (width-to-length ratio 3/2). A variety of new morphological data support the conclusions that (1) M. conodon is a nominal species, (2) the European species M. lemonnieri is not a junior synonym and (3) one of the most complete skeletons of Mosasaurus from South Dakota (SDSM 452) is not assigned to M. conodon (but is likely to be Mosasaurus sp.). To date, M. conodon occurs only in North America during the late Campanian to early Maastrichtian.
Habitat preference of mosasaurs indicated by rare earth element (REE) content of fossils from the Upper Cretaceous marine deposits of Alabama, New Jersey, and South Dakota (USA)
Authors: Harrell T.L. , Pérez-Huerta A. 
Published: January 2015

AbstractKnowledge of habitat segregation of mosasaurs has been based on lithology and faunal assemblages associated with fossil remains of mosasaurs and stable isotopes (δ13C). These approaches have sometimes provided equivocal or insufficient information and, therefore, the preference of habitat by different mosasaur taxa is still suboptimally constrained. The present study is focused on the analysis of rare earth element (REE) ratios of mosasaur fossils from the Upper Cretaceous formations of western Alabama, USA. Results of the REE analysis are used to infer the relative paleobathymetry associated with the mosasaur specimens and then to determine if certain taxonomic groups showed a preference for a particular water depth. Comparisons are then made with mosasaur specimens reported in the literature from other regions of North America from different depositional environments. Results indicate that Mosasaurus, Platecarpus and Plioplatecarpus may have preferred more restricted habitats based on water depth whereas Tylosaurus and Clidastes favoured a wider range of environments. Results also suggest that Plioplatecarpus lived in a shallower environment than its Platecarpus predecessor. Although the results of this study are encouraging, caution must be exercised before drawing any final conclusions due to the small sample size of most of the taxa analysed.
Palaeomagnetism of Mesoproterozoic limestone and shale successions of some Purana basins in southern India
Authors: DE KOCK MICHIEL O. , BEUKES NICOLAS J. , MUKHOPADHYAY JOYDIP 
Published: January 2015

AbstractThe ‘Purana’ basins were long considered Neoproterozoic basins until geochronology and palaeomagnestism showed parts of the Chattisgarth and lower Vindhyan basins to be a billion years older. Historically, the successions in the Chattisgarth Basin are correlated with similar successions in the Pranhita–Godavari and Indravati basins. In India, differentiating between early–late Mesoproterozoic rocks and those spanning the Mesoproterozoic–Neoproterozoic boundary is possible by comparing magnetic declination and inclination; palaeomagnetism is therefore a very useful correlation tool. Here we report a new Stenian-aged palaeopole (50.1°N, 67.4°E, radius of cone of 95% confidence A95 = 12.4°, precision K = 30.1) from carbonate and shale successions of the Pranhita–Godavari and Chattisgarth basins (the C+/– magnetization). In addition, an early diagenetic remagnetization (component A) was identified. No primary or early diagenetic magnetizations were identified from the Indravati Basin. Here, as well as in stratigraphically higher parts of the other two successions, widespread younger magnetic overprints were identified (B+ and B– magnetic components). Our C+/– palaeopole is constrained by palaeomagnetic stability field tests, is different from known 1.4 Ga and 1.0 Ga Indian palaeopoles, but similar to a 1.19 Ga palaeopole. Penganga Group (Pranhita–Godavari Basin) deposition was probably initiated at around 1.2 Ga. A similar palaeomagnetic signature confirms its correlation with the Raipur Group (Chattisgarth Basin), of which the deposition spans most of the Stenian period (c. 1.2–1.0 Ga). Sedimentation in these groups began significantly later than c. 1.4 and c. 1.6 Ga, as suggested by ages reported from below the Raipur and Penganga groups, respectively.
RE-WRITING HISTORY: BERNHARD LANG'SMONADOLOGIESERIES (2007–PRESENT)
Authors: Dysers Christine 
Published: January 2015

AbstractThe oeuvre of Austrian composer Bernhard Lang (b. 1957) is based upon extreme musical repetition. In hisMonadologieseries (2007-present), short samples of pre-existing music form the starting point for a variety of automatically generated looping and transformation processes. The overwriting of pre-existing music results in the creation of meta-compositions that radically alter the listeners' understanding of the original piece.Sketching a general overview of the composer's aesthetic beliefs and the compositional strategies originating from them, this article focuses on Lang'sMonadologieseries. It aims to clarify the relationships between the individual pieces of the series, to analyse the musical techniques used to reinterpret pre-existing scores within a contemporary setting and, finally, to interpret the implications that arise from that procedure. The 2009Monadologie VII: …for Arnold…functions as a historico-analytical case study, from which a deeper insight into the series' hermeneutics can be gained.
Pubertal maturation and affective symptoms in adolescence and adulthood: Evidence from a prospective birth cohort
Authors: Gaysina Darya , Richards Marcus , Kuh Diana , Hardy Rebecca 
Published: January 2015

AbstractThe higher prevalence of affective symptoms among women compared to men emerges in adolescence, and it has been associated with pubertal maturation. However, it remains unclear whether pubertal timing has long-term influences on affective symptoms. Using data from the British 1946 birth cohort, we investigated whether pubertal timing was associated with affective symptoms over the life course, distinguishing those with symptoms in adolescence only, symptoms in adulthood only, and symptoms in both adolescence and adulthood. In females, there was no evidence that early pubertal maturation was a risk factor for affective symptoms. However, those with particularly late menarche (≥15 years) showed a lower risk of adult-onset affective symptoms (odds ratio = 0.54, 95% confidence interval = 0.31, 0.95). This effect of late pubertal timing was not explained by a range of sociobehavioral factors. In contrast, in males, late pubertal timing was associated with increased risk of adolescent-onset affective symptoms that tracked into adulthood (odds ratio = 2.10, 95% confidence interval = 1.44, 3.06). This effect was partly explained by low prepubertal body mass index. Sex-specific effects of pubertal timing on the long-term risk of affective symptoms might be due to different effects of gonadal hormonal on the central nervous system, as well as different social experiences during puberty.

AbstractBackgroundRecent efforts have focused on optimising interstage outcomes, including growth, for infants following the Norwood operation. The impact of the site of interstage care remains unclear, and it has been hypothesised that care at the surgical site may be beneficial due to greater access to resources such as nutritional support. This study evaluated the relationship between site of interstage care and weight gain in a large multicentre cohort.MethodsInfants enrolled in the National Paediatric Cardiology Quality Improvement Collaborative (2008–2013) surviving up to Stage 2 were included. Change in weight-for-age z-score between Norwood discharge and Stage 2 admission was compared in those receiving care at the surgical versus non-surgical site.ResultsOf the 487 interstage survivors, 60% received all care at the surgical site, and 40% received care at a non-surgical site. There was no significant difference between groups in change in weight-for-age z-score: +0.36±0.96 for the surgical site group versus +0.46±1.02 for the non-surgical site group, p=0.3. Results were unchanged in multivariable analysis adjusting for differences in important baseline characteristics, duration of interstage, and home surveillance strategy. The proportion of all patients with weight-for-age z-score <−2 decreased from 40% at Norwood discharge to 29% at Stage 2, with no significant difference in change between the two groups (p=0.1).ConclusionsThe site of interstage care was not associated with weight gain during the interstage period. Nearly one-third of patients overall had a weight-for-age z-score <−2 at Stage 2. Further study is required to identify methods to optimise weight gain in these patients.
What Next for Multilateral Trade Talks? Quantifying the Role of Negotiation Modalities
Authors: DECREUX YVAN , FONTAGNÉ LIONEL 
Published: January 2015

AbstractWhat are the lessons from the Doha Development Agenda (DDA) from a forward-looking point of view? A decade of negotiations is likely to go nowhere. This paper argues that absence of a landing-zone was in the data. Quantitative tools modelling the detail of the modalities predicted failure but were not taken seriously: the design of the negotiations implied that any achievements of the Round could only be limited. Such a weakness was induced by the way multilateral negotiations were organized – in separate groups, without much consideration for, or understanding of, how the different elements added up to more than the sum of the parts. We put sensible figures on that argument by using a dynamic computable general equilibrium model of the world economy, addressing exceptions, flexibilities, as well as the non-linear design of the liberalization formulas, a reduction in domestic support, the phasing out of export subsidies in agriculture, and trade facilitation. Our conclusion is that negotiators have to go back to simplicity and re-bundle the topics if they wish to revamp multilateral negotiations.
Formulas for Failure? Were the Doha Tariff Formulas too Ambitious for Success?
Authors: LABORDE DAVID , MARTIN WILL 
Published: January 2015

AbstractThis paper views tariff-cutting formulas as a potential solution to the free-rider problem that arises when market opening is negotiated bilaterally and extended on a most-favored-nation basis. The negotiators in the Doha Agenda chose formulas that are ideal from an economic efficiency viewpoint in that they most sharply reduce the highest – and most economically – costly tariffs. When the political support that gave rise to the original tariffs is considered, however, this approach appears to generate very high political costs per unit of gain in economic efficiency. The political costs associated with the formulas appear to have led to strong pressure for many, complex exceptions, which both lowered and increased uncertainty about members' market access gains. Where tariff cuts focus on applied rates, it seems likely that a proportional cut rule would reduce the political costs of securing agreements. However, detailed examination of the Doha proposals with their product exceptions suggests that negotiators are likely to find cuts with exceptions politically attractive but economically costly when cuts are based on bound tariffs with different degrees of binding overhang.
A Shifting Mandate: International Ownership, Global Fragmentation, and a Case for Deeper Integration under the WTO
Authors: BLANCHARD EMILY J. 
Published: January 2015

AbstractThis paper reviews several key implications of international investment and global supply chain fragmentation for the multilateral trading system. Based on existing economic research, I identify a two-fold challenge for policy makers: first, to leverage the trade-liberalizing potential of global fragmentation at the multilateral level; and, second, to counter the potential for opportunistic manipulation of behind-the-border policy instruments.
Psychopathological Factors that can Influence Academic Achievement in early Adolescence: a Three-Year Prospective Study
Authors: Voltas Núria , Hernández-Martínez Carmen , Aparicio Estefania , Arija Victoria , Canals Josefa 
Published: January 2015

AbstractThis three-phase prospective study investigated psychosocial factors predicting or associated with academic achievement. An initial sample of 1,514 school-age children was assessed with screening tools for emotional problems (Screen for Childhood Anxiety and Related Emotional Disorders; Leyton Obsessional Inventory-Child Version; Children’s Depression Inventory). The following year, 562 subjects (risk group/without risk group) were re-assessed and attention deficit/hyperactivity disorder (ADHD) was assessed. Two years later, 242 subjects were followed, and their parents informed about their academic achievement. Results showed that early depression (phase 1 B = –.130, p = .001; phase 1 + phase 2 B = –.187, p < .001), persistent anxiety symptoms (phase 1 + phase 2 B = –1.721, p = .018), and ADHD were predictors of lower academic achievement (phase 1 + phase 2 B = -3.415, p = .005). However, some anxiety symptoms can improve academic achievement (Social phobia B = .216, p = .018; Generalized anxiety B = .313, p < .001). Socio-economic status (SES) was positively related to academic achievement. We can conclude that in the transition period to adolescence, school-health professionals and teachers need to consider the emotional issues of students to avoid unwanted academic outcomes.
The Effect of the Emotive Decisions in Prospect Theory
Authors: Bonavia Tomas 
Published: January 2015

AbstractThe main purpose of this paper was to show that the certainty and reflection effects of prospect theory do not occur when stimuli have an affective value. To this end, 160 participants were asked to reply to a series of problems originally designed by Kahneman and Tversky (1979), but modified according to the contributions of Rottenstreich and Hsee (2001). The sample was divided into four experimental conditions, two in a gain situation and two in a loss situation. In both cases, affect-rich and affect-poor stimuli were applied in sure and probable alternatives. The findings showed that, in agreement with our hypotheses, the affective value of the stimuli altered the outcome predicted by prospect theory, showing response patterns contrary to certainty and reflection effects (p ≤ .01 and p ≤ .05 respectively). Therefore, this research supports the influence of the emotions in the decision-making process, and should be extended to other aspects of prospect theory.

Published: January 2015

AbstractAlthough in the last years several studies comparing male and female pathological gamblers have been published, most of them have been carried out using only samples of males. The aim of this study was to investigate gender differences in a sample of subjects diagnosed with pathological gambling (PG) attending three specialized outpatient units. Retrospective study was carried out of 96 patients (49% female and 51% male), comparing the main socio-demographic, clinical, and behavioral data. Most subjects (94%) met the criteria for pathological gambling. No significant differences between sexes were found in the severity of gambling behavior or the socio-demographic variables studied. Whereas slot machines were the main type of game for most subjects, a higher percentage of women were addicted to bingo (χ2(1, 4)= 5.19,p =.029 Cohen’sd= 0.48) and had more than one type of game as a secondary addiction χ2(1, 4)= 7.63,p =.006; Cohen’sd =0.59) . Women started gambling at a later age than men (t(94)= 2.95,p= .004; Cohen’sd =0.60), but developed a pattern of addiction faster (t(94)= 2.95,p= .004; Cohen’sd =–0.61) . Women also had higher comorbidity with other psychiatric disorders (χ2(1)= 7.28,p =.007; Cohen’sd =0.57), specifically with affective (χ2(1)= 11.31,p =.001; Cohen’sd =0.73) and personality disorders (χ2(1)= 4.71,p =.030; Cohen’sd =0.45). Our results indicate the existence of differences between women and men in the pattern of gambling behavior and in psychiatric comorbidity. These aspects should be considered in the design of treatment programs for pathological gamblers.
Undershoot suppression technique for fully integrated pulse‐width modulated switching converters
Authors: Huang Cheng , Mok Philip K.T. 
Published: December 2014

A shunt‐regulation control technique is presented to improve the load transient performance of fully integrated high‐frequency converters. The undershoot voltage, which used to be limited by the system loop response and the nanofarad range small on‐chip capacitor, is significantly suppressed. The proposed converter is simulated by a standard 0.13 μm CMOS process using a 6 nH inductor and 10 nF capacitor under different process corners with parasitics extracted from the layout of critical blocks. Compared to a conventional converter with the bandwidth pushed to the limit, the undershoot voltage is reduced from 360 to 100 mV with a transient step of 150–550 mA in 100 ps.

Authors: Wang Han , Zhang Zhijun , Feng Zhenghe 
Published: December 2014

A dual‐port planar MIMO antenna designed for 2.4 GHz WLAN applications is presented. It consist of two X‐shaped arms etched on a square‐shaped substrate, which forms a self‐decoupled structure that can generate two orthogonal modes with ultra‐high isolation. In measurement, the −10 dB bandwidth covers from 2.39 to 2.51 GHz, and better than 43 dB isolation is achieved between the two ports. Meanwhile, the patterns are orthogonal, and the envelope correlation coefficient is only 0.0052. The antenna it is fabricated on FR‐4 substrate, and the size is only 33 × 33 × 3.2 mm, which is very much suited to space‐limited MIMO applications that require ultra‐high isolation, good pattern diversity and low fabrication cost.
Source follower‐based high‐speed switched capacitor amplifier for pipelined ADCs
Authors: Qiu Lei , Zheng Yuanjin , Siek Liter 
Published: December 2014

A low‐power high‐speed source follower‐based switched capacitor (SC) amplifier for pipelined analogue‐to‐digital converters (ADCs) is proposed. Using the source follower as the core of the SC amplifier, the power consumption can be significantly reduced while obtaining the same linearity and bandwidth. Meanwhile, through replicating the input signal to the drain of the input transistor, the channel‐length modulation effect can be suppressed, achieving a high linearity (>60 dB). The functionality and linearity of the proposed SC amplifier are verified by simulation results.
