The quantum divided power algebra of a finite-dimensional Nichols algebra of diagonal type

Let $\mathcal{B}_\mathfrak{q}$ be a finite-dimensional Nichols algebra of diagonal type corresponding to a matrix $\mathfrak{q}$. We consider the graded dual $\mathcal{L}_{\mathfrak{q}}$ of the distinguished pre-Nichols algebra $\widetilde{\mathcal{B}}_{\mathfrak{q}}$ from [A3] and the divided powers algebra $\mathcal{U}_{\mathfrak{q}}$, a suitable Drinfeld double of $\mathcal{L}_{\mathfrak{q}} # \mathbf{k} \mathbb{Z}^{\theta}$. We provide basis and presentations by generators and relations of $\mathcal{L}_{\mathfrak{q}}$ and $\mathcal{U}_{\mathfrak{q}}$, and prove that they are noetherian and have finite Gelfand-Kirillov dimension.
Characterization of polycaprolactone and starch blends for potential application within the biomaterials field

Thermally blending starch and polycaprolactone with the compatibilizer methylenediphenyl diisocyanate (MDI) distributed in the polyester phase had been previously confirmed to enhance the mechanical properties and interface between the two phases of the blends. In this study, blends of polycaprolactone with various levels of starch and 1.0% MDI were prepared through melt blending using a twin-screw extruder, and an extensive characterization including mechanical properties, microstructure, melting, thermo-mechanical behaviour, hydrophilicity and degradation in Hank’s solution were further carried out, aiming at an alternative for orthopaedic applications. The results demonstrated that MDI had improved the mechanical properties of polycaprolactone (PCL) and starch blends, but an optimal ratio of starch level and MDI content was required, which had been found to be 1.0 wt % MDI with 30 wt % starch content. The present study indicated the starch and polycaprolactone blends may present a significant potential for biomedical applications. Key words: Polycaprolactone, starch blends, biomaterials.
Pure spin currents in magnetically ordered insulator/normal metal heterostructures

Pure spin currents, i.e. the transport of angular momentum without an accompanying charge current, represent a promising new avenue in modern spintronics from both a fundamental and an application point of view. Such pure spin currents are not only able to flow in electrical conductors via mobile charge carriers, but also in magnetically ordered electrical insulators as a flow of spin excitation quanta. Over the course of the last few years, remarkable results have been obtained in heterostructures consisting of magnetically ordered insulators interfaced with a normal metal, where a pure spin current flows across the interface. This topical review article deals with the fundamental principles, experimental findings and recent developments in the field of pure spin currents in magnetically ordered insulators. Here, we focus on four different manifestations of pure spin currents in such heterostructures: the spin pumping effect, the longitudinal spin Seebeck effect, the spin Hall magnetoresistance and the all-electrical injection and detection of magnon transport in non-local device concepts. In this article, we utilize a common theoretical framework to explain all four effects and explain the important material systems (especially rare-earth iron garnets) used in the experiments. For each effect, we introduce basic measurement techniques and detection schemes and discuss their application in the experiment. We account for the remarkable progress achieved in each field by reporting recent developments and by discussing the research highlights obtained by our group. Finally, we conclude the review article with an outlook on future challenges and obstacles in the field of pure spin currents in magnetically ordered insulator/normal metal heterostructures. This topical review aims to be a useful introductory resource for readers from the outside or just starting in this field, and also provides perspective for those who already have an established understanding of the underlying physics.
An Analytical Model for the Lift on an Inline Oscillating Cylinder under No Resonance Condition

An analytical model under the no resonance condition is developed to determine the lift on inline oscillating circular cylinder under the lock-on regime. From numerical simulations of the flow field, lift coefficient data are obtained over the inline oscillating circular cylinder. Spectral analysis is applied to the data to characterize the non-linear coupling between the vortex shedding frequency and its third harmonic. From this analysis it is concluded that the van der Pol equation should be used to model the lift coefficient on inline oscillating circular cylinder in the lock-on regime.
32. OXIDATION FRONTS IN MADEIRA ABYSSAL PLAIN TURBIDITES: PERSISTENCE OF EARLY DIAGENETIC TRACE-ELEMENT ENRICHMENTS DURING BURIAL, SITE 950 1

The emplacement of organic-rich turbidite units on abyssal plains is commonly followed by the early diagenetic redistribution of redox-sensitive elements. This occurs only at the summit of the turbidite unit, where it is caused by the downward diff usion of seawater oxygen, which continues for as long as each turbidite is in diffusive contact with bottom waters. The duration of this process is generally a few tens of thousands of years on the Madeira Abyssal Plain (MAP), where turbidite emplacement occurs at frequent intervals. The known sequence of redox-sensitive element redistribution peaks around oxidation fronts in tur bidites, derived from studies of conventional piston core material sampling the upper few tens of meters of Quaternary sediments on the MAP, is compared here with that in a single turbidite recovered at Site 950, and now buried to 230 mbsf. This unit was deposited during the late Miocene (~7.6 Ma) and has experienced consecutively post-oxic and sulfate-reducing conditions during burial. The organic carbon (C org) profile and C org/S ratio are remarkably similar to those in more recent examples. The labile (nondetrital) fractions of many redox-sensitive elements remain concentrated around a sharp color change from dark green (below) to greenish gray (above), which marks the limit of penetration of oxygen when the turbidite top was exposed on the seafloor. The elements Cd, Sb, Se, Tl, and V are all still found in peaks immediately below the original oxic/post-oxic boundary although, as in the younger turbidites, the peak maxima are not exactly coincident. Cobalt, Cu, Ni, and Zn have apparently moved upward in chromatographic-like fronts, which are seen as thin dark-purple or gray bands in the core. Labile As, S, and U, which were selectively removed from sediment above the color change by the bacterially driven redox processes that accompanied the oxic decomposition of Corg in the turbidite, have retained their characteristic stepped-concentration profiles. The successive passage through ~130 m of post-oxic and ~100 m of sulfate-reducing conditions (each lasting ~3.8 m.y.) has had remarkably little effect on trace-metal distributions.
Work Addiction is not New to the Psychological Literature and has Evolved over Time

In a recent edition of the journal Addiction, Kardefelt-Winther et al. [1] drew attention to the conceptualization and assessment of behavioural addiction and argued that it may lead to pathologizing of common activities. One such example provided by the authors was work addiction. Consequently, readers might have been left with the impression that work addiction is a newly developed concept. However, this is not the case. The occurrence of psychosomatic symptoms on days where individuals were unable to work can be traced back to 1919 [2], while the formal notion of work addiction entered the psychological literature almost 50 years ago following the publication of Oates’ seminal book, Confessions of a Workaholic [3] with a large increase in papers on the disorder over the last 30 years [4]. Consequently, work addiction is not a recently identified problem. Furthermore, work addiction also fits well into Kardefelt-Winther et al.’s [1] conceptualization of a behavioural addiction. More specifically, three principal observations are worth noting.
TIM OLIVER BERG Cross-country evidence on the relation between equity prices and the current account Institute for Monetary and Financial Stability

This paper explores the relationship between equity prices and the current account for 17 industrialized countries in the period 1980-2007. Based on a panel vector autoregression, I compare the effects of equity price shocks to those originating from monetary policy and exchange rates. While monetary policy shocks have a limited impact, shocks to equity prices have sizeable effects. The results suggest that equity prices impact on the current account through their effects on real activity and exchange rates. Furthermore, shocks to exchange rates play a key role as well.
Effects of Black Pepper (Piper nigrum Linn.) Extract on Sexual Drive in Male Mice

Black pepper (Piper nigrum L.), known as the king of spices, proven to contain various types of active substances that are allegedly beneficial to the human body functions including sexual function. This study was conducted to determine whether black pepper extract can be used to improve sexual function in male subjects. Thirty six healthy male mice, four months old, weighing between 25-30 g, were used as experimental animals and grouped into four. The first one mice was given pellets that do not contain black pepper extract as a control. The second and third groups, respectively were treated with pellets containing aqueous and ethanol extracts. The last group was given pellets containing aqueous extract and ethanolic extracts with a ratio of 1:1. Pellets were given once every day for 90 days. Mating behavior test was conducted in an open round plastic tray with a diameter of 40 cm and height 25 cm. Throughout the test, videotaping was performed for the following parameters: courtship latency and mounting frequency. The results revealed that compared with control group, male mice fed on aqueous as well as ethanol extract of black pepper significantly showed a shorter courtship latency (p<0.05). On the other hand, there was no difference in the mounting frequency between treated groups. Interestingly, the mounting frequency showed a strong negative correlation with the courtship latency (r = -0.968). In conclusion, the fruit extract of black pepper potentially affect sexual drive in male mice.
Residual stress measurements and structural integrity implications for selective laser melted TI-6al-4v#

Selective laser melting (SLM) of Ti-6Al-4V has significant potential in the aerospace and biotechnology industries. SLM employs a focused laser beam to melt successive layers of metallic powder into complex components. This process can result in the generation of high thermally-induced residual stresses. These residual stresses, together with micro-flaws/ pores from the inherent fabrication process, may lead to premature fatigue crack initiation and propagation at relatively low cyclic stresses. The hole-drilling strain gauge method was used to evaluate residual stresses within SLM Ti-6Al-4V specimens, with the intention of understanding the associated mechanisms for the successful application of SLM Ti-6Al-4V in industry.
High occurrence of new particle formation events at the Maïdo high-altitude observatory (2150 m), Réunion (Indian Ocean)

Abstract. This study aims to report and characterise the frequent new particle formation (NPF) events observed at the Maïdo observatory, Réunion, a Southern Hemisphere site located at 2150 m (a.s.l.) and surrounded by the Indian Ocean. From May 2014 to December 2015, continuous aerosol measurements were made using both a differential mobility particle sizer (DMPS) and an air ion spectrometer (AIS) to characterise the NPF events down to the lowest particle-size scale. Carbon monoxide (CO) and black carbon (BC) concentrations were monitored, as well as meteorological parameters, in order to identify the conditions that were favourable to the occurrence of nucleation in this specific environment. We point out that the annual NPF frequency average (65 %) is one of the highest reported so far. Monthly averages show a bimodal variation in the NPF frequency, with a maximum observed during transition periods (autumn and spring). A high yearly median particle growth rate (GR) of 15.16 nm h−1 is also measured showing a bimodal seasonal variation with maxima observed in July and November. Yearly medians of 2 and 12 nm particle formation rates (J2 and J12) are 0.858 and 0.508 cm−3 s−1, respectively, with a seasonal variation showing a maximum during winter, that correspond to low temperature and RH typical of the dry season, but also to high BC concentrations. We show that the condensation sink exceeds a threshold value (1.04×10−3 s−1) with a similar seasonal variation than the one of the NPF event frequency, suggesting that the occurrence of the NPF process might be determined by the availability of condensable vapours, which are likely to be transported together with pre-existing particles from lower altitudes.

Pardosa vlijmi sp. nov., a new ethospecies sibling Pardosa proxima (C.L. Koch, 1848), from France, with description of courtship display (Araneae, Lycosidae)

A new species of the wolfspider genus Pardosa C. L. Koch, 1848, P. vlijmi, is described from France. The species, which is morphologically almost identical to P. proxima (C. L. Koch, 1848), regarding both males and females, differs clearly from the latter in its pattern of courtship behaviour. The courtship patterns of P. vlijmi and P. proxima are compared on the basis of a detailed analysis.
Scale effect on runoff and soil loss control using rice straw mulch under laboratory conditions

Abstract. Amendments can control the runoff and soil loss by protecting the soil surface. However, scale effects on runoff and soil loss control have not been considered yet. The present study has been formulated to determine the efficiency of two plot sizes of 6 and 0.25 m2 covered by 0.5 kg m−2 of straw mulch with regard to changing the time to runoff, runoff coefficient, sediment concentration and soil loss under laboratory conditions. The study used a sandy-loam soil taken from summer rangeland, Alborz Mountains, northern Iran, and was conducted under simulated rainfall intensities of 50 and 90 mm h−1 and in three replicates. The results of the study showed that the straw mulch had a more significant effect on reducing the runoff coefficient, sediment concentration and soil loss on a 0.25 m2 plot scale. The maximum effectiveness in time to runoff for both the scales was observed at a rainfall intensity of 90 mm h−1. The maximum increasing and decreasing rates in time to runoff and runoff coefficient were observed at a rainfall intensity of 90 mm h−1, with 367.92 and 96.71% for the 0.25 m2 plot and 110.10 and 15.08% for the 6 m2 plot. The maximum reduction in the runoff coefficient was in the 0.25 m2 plot for the two rainfall intensities of 50 and 90 mm h−1, with rates of −89.34 and −96.71%. The maximum change in soil loss at the intensities of both 50 and 90 mm h−1 occurred in the 0.25 m2 plot, with 100%, whereas in the 6 m2 plot, decreasing rates of soil loss for the intensities of both 50 and 90 mm h−1 were 46.74 and 63.24%, respectively.
Spatial sampling in human visual cortex is modulated by both spatial and feature-based attention

Spatial attention changes the sampling of visual space. Behavioral studies suggest that feature-based attention modulates this resampling to optimize the attended feature's sampling. We investigate this hypothesis by estimating spatial sampling in visual cortex while independently varying both feature-based and spatial attention. Our results show that spatial and feature-based attention interacted: resampling of visual space depended on both the attended location and feature (color vs. temporal frequency). This interaction occurred similarly throughout visual cortex, regardless of an area's overall feature preference. However, the interaction did depend on spatial sampling properties of voxels that prefer the attended feature. These findings are parsimoniously explained by variations in the precision of an attentional gain field. Our results demonstrate that the deployment of spatial attention is tailored to the spatial sampling properties of units that are sensitive to the attended feature.
An Evolutionary and Ecological Perspective of the Insect Fauna of Ferns

Analysis of the number and distribution of insects attacking ferns demonstrates that significantly fewer insects than expected utilize ferns as a food source. Also, insects which do attack ferns are not a representative sample of phytophagous insects in general. Analysis of the feeding habits of these insects indicates that few families or even genera of insects have specialized on ferns. Juxtaposition of the evolutionary histories of ferns and phytophagous insect groups fails to adequately explain the anomalies seen, since evolutionarily old groups are no better represented on ferns than younger groups. Differences in morphological complexity between angiosperms and ferns (primarily lack of flowers) probably accounts for a portion of the underutilization of ferns, but chemical defense mechanisms and ecological characteristics such as population size or phenology may be of importance. The present insect fauna of ferns appears to have been derived from insects utilizing woody plants via host-plant switching.
Socially Mediated Internet Surveys: Recruiting Participants for Online Experiments

Abstract The Socially Mediated Internet Survey (SMIS) method is a cost-effective technique used to obtain web-based, adult samples for experimental research in political science. SMIS engages central figures in online social networks to help recruit participants among visitors to these websites, yielding sizable samples for experimental research. We present data from six samples collected using the SMIS method and compare them to those gathered by other sampling approaches such as Amazon's Mechanical Turk. While not representative of the general adult population, our SMIS samples are significantly more diverse than undergraduate convenience samples, not only demographically but also politically. We discuss the applicability of the method to experimental research and its usefulness for obtaining samples of special, politically relevant subpopulations such as political sophisticates and activists. We argue that the diversity of SMIS samples, along with the ability to capture highly engaged citizens, can circumvent questions about the artificiality of political behavior experiments entirely based on student samples and help to document sources of heterogeneous experimental treatment effects.
Pretreatment serum lactate level as a prognostic biomarker in patients undergoing supratentorial primary brain tumor resection

Introduction Malignant primary brain tumors are one of the most aggressive cancers. Pretreatment serum nonneuronal biomarkers closely associated with postoperative outcomes are of high clinical relevance. The present study aimed to identify potential pretreatment serum biomarkers that may influence oncological outcomes in patients with primary brain tumors. Methods A total of 74 patients undergoing supratentorial primary brain tumor resection were enrolled. Before tumor resection, serum neuronal biomarkers, namely neuron-specific enolase (NSE), S100β, and glial fibrillary acidic protein (GFAP), and serum nonneuronal biomarkers, namely neutrophil gelatinase-associated lipocalin (NGAL), lactate dehydrogenase (LDH), and lactate, were measured and associated postoperative oncological outcomes, including brain tumor grading, progression-free survival (PFS), and overall survival (OS), were compared. Results Patients with high-grade brain tumors had significantly higher pretreatment serum lactate levels (p = 0.011). By contrast, other biomarkers were comparable between patients with high-grade and low-grade brain tumors. Receiver operating characteristic curve analysis of serum lactate levels yielded an area under the curve of 0.71 for differentiating between high-grade and low-grade brain tumors. Kaplan–Meier survival analysis revealed patients with high serum lactate levels (≧2.0 mmol/L) had shorter PFS and OS (p = 0.021 and p = 0.093, respectively). In a multiple regression model, only elevated serum lactate levels were associated with poor PFS and OS (p = 0.021 and p = 0.048, respectively). Conclusions An elevated pretreatment serum lactate level is a prognostic biomarker of high-grade primary brain tumors and is significantly associated with poor PFS in patients with supratentorial brain tumors undergoing tumor resection. By contrast, other serum biomarkers are not significantly associated with oncological outcomes.
Improvement of the Fatigue Resistance and Increase Its Life of Specimens of Naval Brass Alloy Using Laser Shock Wave Processing

Laser shock processing (LSP) was performed on naval brass alloy specimen to reveal effectiveness on fatigue life. LSP experimental array was performed as follows: A convergent lens was used to deliver 0.5-1 J/pulse (1064 nm). In a 10 ns, laser FWHM pulse produced by Q-switched Nd:YAG laser of 6 Hz with spots of 0.5-2 mm in diameter moving forward along the work piece with pulse density of 500 pulses/cm 2 . Deionized water (3 mm thickness) was used as a transparent confining layer while the non-prate black paint (20 μm thickness) was used as an absorbing layer of laser beam. The optimum values of 1mm spot size, pulse energy of 1 J. LSP effective parameters, microstructure and fatigue life test were evaluated. Chemical composition analysis was conducted. The microstructure analysis included surface morphology by SEM, grain analysis by AFM. The results demonstrated that the LSP can be improving fatigue resistance for specimens which were used in this work by comparing with the untreated specimens. The fatigue life’s of the specimens after LSP was obviously increased by 64% at lower stress level due to the compressive residual stresses near the surface.
Vlerick Working Papers 2002/09 IS DESIGN - MANUFACTURING INTEGRATION THAT IMPORTANT?

There is limited empirical evidence to support the importance of design-manufacturing (DM) integration on the performance of new product development projects. This article focuses on the impact of integration processes and their outcomes on multidimensional project performance. When considering integration as interaction processes, we find that the degree of interaction is positively correlated with respect for time and prestige. If one succeeds in smoothing the production start-up, which is an outcome of integration, a better respect for time, budget and technical specifications is realized. Finally, we provide some insights into the perceived room to improve integration. Even though perceptions do not always correspond with reality, it is interesting to examine them since product development decisions are often taken in response to an individual’s perceptions (Kleinschmidt & Cooper, 1995).
