Magnetoplasmonic nanoparticles for photothermal therapy

Magnetoplasmonic nanoparticles for photothermal therapy Following the urge to obtain new "smart" nanomaterials, the application of nanotechnology to medicine (nanomedicine) is developing towards new employments of great impact. This is the case of hyperthermia, where superparamagnetic and plasmonic nanoparticles are investigated as nanoheaters or nanotransducers, which can be activated remotely by radiations minimally harmful to physiological tissue and fluids. Furthermore, iron oxide - gold/silver nanocomposites offer the combination of the unique features of both gold/silver and iron oxide nanomaterials to enable applications in diagnostic and therapeutic environments. In this work, a detailed study of the aqueous synthesis of iron oxide - gold/silver nanocomposites is presented. This method uses citric acid as stabilizing agent and (3-aminopropyl)triethoxysilane (APTES) for the dual functions of attaching fine gold and silver nanoparticles onto the magnetite surface as well as preventing the formation of aggregates. The reduction of the metal nanoparticles was achieved thanks to tannic acid. In addition, the possible further applicability of tannic acid as stabilizing agent is analyzed. Morphology, structure, composition and stability were characterized with Transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR) and ζ potential. Magnetic and optical properties were analyzed with vibrating sample magnetometry (VSM) and ultraviolet – visible spectroscopy. These structures maintained the optical and magnetic features of gold/silver and iron oxide nanoparticles.
Adaption of multi-physics PEM fuel cell model using sensitivity analysis

This paper presents the adaption of an existing multiphysics 1D fuel cell model to an existing PEM fuel cell system. The input parameters of the model are separated into system properties, linked to physical values, and running conditions. On the 40 system properties required, a sensitivity analysis was applied in order to identify that only four membrane properties have the most influence on the stack voltage. These parameter values were identified by optimization. The prediction accuracy with the new parameter values decreased to 1.48%.
Validating analogically generated Indonesian words using Fisher’s exact test

We address the issue of generating previously unseen word forms by filling empty cells inside analogical grids. We verify the plausibility of these generated word forms using a morphological analyzer and count how many of them are valid word forms. In this paper, we compare the ratio of valid word forms generated from analogical grids constructed from the list of word forms contained in an annotated Indonesian corpus. We use different word vector representations and saturation thresholds to construct the analogical grids and compare with the use of Fisher’s exact test to measure the confidence of filling an empty cell. The experimental results show that although the confidence is low in general, using Fisher’s exact test gives twice more confidence when generating validated word forms.

A Note on a Cointegrating Vector for US Interest Rate Swaps

This note explores the temporal relationship among US interest rate swap spreads, US corporate credit spreads, LIBOR and the shape of the Treasury yield curve by performing cointegration test and estimating an error correction model. One cointegrating relationship is found, implying that a single common factor underlies these time series and a stable long-run linear relationship exists among them. In addition, the obtained cointegrating vector provides evidence for the existence of complex dynamics between the swap and the equity markets in the US.
Molecular Weight and Structural Properties of Biodegradable PLA Synthesized with Different Catalysts by Direct Melt Polycondensation

Production of biodegradable polylactic acid (PLA) from biomassbased lactic acid is widely studied for substituting petro-based plastics or polymers. This study investigated PLA production from commercial lactic acid in a batch reactor by applying a direct melt polycondensation method with two kinds of catalyst, γ-aluminium(III) oxide (γ-Al 2 O 3 ) or zinc oxide (ZnO), in reduced pressure. The molecular weight of the synthesized PLA was determined by capillary viscometry and its structural properties were analyzed by functional group analysis using FT-IR. The yields of polymer production with respect to the theoretical conversion were 47% for γ-Al 2 O 3 and 35% for ZnO. However, the PLA from ZnO had a higher molecular weight (150,600 g/mol) than that from γ-Al 2 O 3 (81,400 g/mol). The IR spectra of the synthesized PLA from both catalysts using polycondensation show the same behavior of absorption peaks at wave numbers from 4,500 cm -1 to 500 cm -1 , whereas the PLA produced by two other polymerization methods – polycondensation and ring opening polymerization –showed a significant difference in % transmittance intensity pattern as well as peak area absorption at a wave number of 3,500 cm -1 as –OH vibration peak and at 1,750 cm -1 as –C=O carbonyl vibrational peak.
Zero-Shot Cross-lingual Name Retrieval for Low-Resource Languages

In this paper we address a challenging cross-lingual name retrieval task. Given an English named entity query, we aim to find all name mentions in documents in low-resource languages. We present a novel method which relies on zero annotation or resources from the target language. By leveraging freely available, cross-lingual resources and a small amount of training data from another language, we are able to perform name retrieval on a new language without any additional training data. Our method proceeds in a multi-step process: first, we pre-train a language-independent orthographic encoder using Wikipedia inter-lingual links from dozens of languages. Next, we gather user expectations about important entities in an English comparable document and compare those expected entities with actual spans of the target language text in order to perform name finding. Our method shows 11.6% absolute F-score improvement over state-of-the-art methods.
Wheel Skid Correction is a Prerequisite to Reliably Measure Wheelchair Sports Kinematics Based on Inertial Sensors

Accurate knowledge of wheelchair kinematics during a match could be a significant factor in performance improvement in wheelchair basketball. To date, most systems for measuring wheelchair kinematics are not suitable for match applications or lack detail in key kinematic outcomes. This study describes the construction of wheel skid correction algorithms when using a three inertial measurement unit (IMUs) configuration for estimating wheelchair kinematics. The reliability of the skid corrected outcomes was assessed in wheelchair basketball match-like conditions. Twenty participants performed a series of tests reflecting different motion aspects of wheelchair basketball. IMU based estimations were compared to the outcomes of a 24-camera optical motion analysis system serving as gold standard. Once the skid correction algorithms were applied, estimation errors were reduced up to 4% of their original magnitude. Calculated Root Mean Square Errors (RMSE) showed good estimates for frame displacement (RMSE 0.05m) and speed (RMSE 0.1m/s) except for three truly vigorous tests. Estimates of horizontal frame rotation (RMSE<3°) and rotational speed (RMSE<7°/s) were very accurate in all conditions. Differences in calculated instantaneous rotation centers (IRC) were small, but somewhat larger in tests performed at high speed (RMSE up to 0.19m). Average test outcomes for linear speed (ICCs > 0.90), rotational speed (ICC>0.99) and IRC (ICC> 0.90) showed high correlations between IMU data and gold standard. Results indicate that wheel skid correction is a prerequisite to reliably measure wheelchair kinematics in sports conditions. Once applied, this method using cheap and affordable sensors, might enable prospective research in wheelchair basketball match conditions and contribute to individual support of athletes in everyday sports practice. © 2015 The Authors.

Design of an Underactuated Legged Robot With Prismatic Legs for Passive Adaptability to Terrain

Legged robots have the advantage of being able to maneuver unstructured terrains unlike their wheeled counterparts. However, many legged robots require multiple sensors and online computations to specify the gait, trajectory or contact forces in real-time for a given terrain, and these methods can break down when sensory information is unreliable or not available. Over the years, underactuated mechanisms have demonstrated great success in object grasping and manipulation tasks due to their ability to passively adapt to the geometry of the objects without sensors. In this paper, we present an application of underactuation in the design of a legged robot with prismatic legs that maneuvers unstructured terrains under open-loop control without any sensing. Through experimental results, we show that prismatic legs can support a statically stable stance and can facilitate locomotion over unstructured terrain while maintaining its body posture.
The Effect of Short-Term Supplementation of Melissa Officinalis Extract on the Level of Serum Malondialdehyde and Total Antioxidant Capacity after Aerobic Activity at a Negative Slope

The aim of this study was to investigate the effects of downhill running and short-term supplementation of Melissa officinalis on the level of serum Malondialdehyde and total antioxidant capacity in male athletes. In this study, 20 healthy male athletes were randomly divided into two groups of 10 subjects (supplement and placebo). The level of serum Malondialdehyde and total antioxidant capacity were measured before and after supplementation. After data collection, repeated variance analysis test for investigating time series and if significant, Bonferroni post hoc test was used and independent t-test was used to assess the differences between groups. The level of significance of (p≤0.05) was used. The study findings showed that the level of serum Malondialdehyde in the supplement group was increased less than placebo. Also, the total antioxidant capacity rate in the supplement group was more. In general, it is concluded that this herbal supplement can prevent the increase of serum malondialdehyde level and increase the total antioxidant capacity.
An air-bubble screen used as a countermeasure to reduce erosion in open-channel bends

In open-channel bends, interactions between streamwise flow, curvature-induced secondary flow and sediment transport lead to a typical bar-pool bed topography. Erosion occurs near the outer bank that can endanger structures, whereas deposition occurs near the inner bank that can reduce the navigable width. Laboratory experiments have been performed in a sharp open-channel bend to investigate how a bubble screen can influence the bend hydrodynamics and morphological evolution. A porous tube placed near the outer bank and connected at both ends to a pressurized-air system generated a bubble screen strong enough to counteract the descending velocities of the curvature-induced secondary flow. Foregoing clear-water scour experiments with and without the bubble screen have shown that the bubble screen modifies the velocity distribution and acts directly on the bend morphology by shifting the region of maximum scour further away from the outer bank. In the reported study, similar experiments have been performed under live-bed conditions. Measurements of the threedimensional flow field and topography were compared and allowed estimating the beneficial effect of the bubble screen. In the upstream part of the bend, the redistribution of velocity pattern is not sufficient to strongly modify the morphology whereas at the downstream part of the bend, the scour hole is reduced and shifted from the outer bank to the middle of the cross-section.
Expression of resistin in testis and epididymis of bulls

The resistin is an insulin-antagonizing factor that also plays a regulatory role in inflammation, immunity, food intake, and gonadal function. Although adipose tissue is the primary source of resistin, it is also expressed in other tissues, including the testis. This study was aimed to investigate the immunohistochemical (IHC) localization of resistin in testicular tissues of Holstein bulls. Mouse monoclonal antibody anti-resistin as primary antibody and rabbit anti-mouse IgG Horseradish Peroxidase (HRP) as secondary antibody were used. Samples of testis were collected from four bulls aged of 1.5 to 2 years old, and preserved in 10% formalin for posterior inclusion in paraffin. Histological sections with 5 micron in thickness were prepared for IHC. Immunoreactions were assessed for spermatogenic cells, Leydig cells, Sertoli cells and epididymis. Our results showed that the resistin is expressed in the testis. Immunoreactions were observed in Sertoli cells, Leydig cells, spermatogonia cells and cytoplasm of ciliated cells of the epididymis. But, the intensity of staining in Leydig cells and epididymis was very weak in comparison with other cells. Probably, resistin had autocrine effect in testis, therefore it could be involved in spermatogenesis and sperm motility.

Diferencias de género en estrategias y estilos de aprendizaje

Gender differences in learning strategies and styles. This study highlights some limitations of research into gender differences in learning strategies and styles (LSS) and these differences are analysed in relation to some contextual variables. 991 university students took 4 tests (LASSI, ILP, ASI and LSQ). Data obtained were subjected to a 2 x 3 x 2 MANOVA (gender-discipline-year) analysis which r evealed statistically significant effects for both these factors and gender x discipline interaction. Results of the discriminant analyses for each level of the discipline factor lead to two conclusions. First, LSS that differenciate between men and women (self-testing, relating ideas, etc.) were related to the type of discipline studied. Second, in all disciplines (pure sciences, social sciences, arts) female students showed more fear of failure. In all disciplines except arts, male students showed more ne gative attitudes towards academic study.
New fundamental and environmental aspects of atmospheric corrosion

Atmospheric corrosion involves chemical, electrochemical, and physical processes in three phases (solid, liquid, and gas) and two interfaces (solid/liquid and liquid/gas). Because of inherent experimental and conceptual difficulties, scientific efforts to characterize this highly complex interfacial regime came relatively late into the field. With the access and development of surface and interface sensitive analytical techniques, it has lately become possible to perform molecular in situ analyses of the interfaces involved in atmospheric corrosion. This lecture presents some highlights from our fundamental research in atmospheric corrosion, performed at the Royal Institute of Technology in Stockholm, Sweden. It includes results from the most recent efforts in our research group to provide a molecular understanding of the interfacial regime that governs atmospheric corrosion. Using copper or zinc as substrate and carboxylic acid as corrosion stimulator in the humidity-containing atmosphere, results have been obtained with particular emphasis on probing the metal oxide/water interface (by infrared reflection absorption spectroscopy (IRAS) combined with the quartz crystal microbalance (QCM) and sum frequency generation (SFG)) and the water/gas interface (by SFG), respectively. While research in atmospheric corrosion traditionally has aimed at understanding how the environment influences the metal, the opposite question- how the metal influences the environment during atmospheric corrosion- may be of equally technical importance. Some examples of on-going research on new environmental aspects of atmospheric corrosion of zinc will also be presented.
Numerical Modelling of Damage Response of Layered Composite Plates

The paper addresses the problem of impact on layered fibre composites. The behaviour of composite laminates under impact loading is dependent not only on the velocity but also on the mass and geometry of the impactor. Using micromechanical Mori-Tanaka approach, mechanical properties of the laminate have been calculated utilizing the material constants of the fibre and matrix. General purpose FEM software ABAQUS has been modified by means of user written subroutines for modelling of composite laminate and rigid impactor. The kinematics of the impact has been simulated using transient dynamic analysis. Employing user defined multi point constraints, delamination zones have been modeled and visualised
On discrete and continuous state adaptive network models

We consider adaptive network models with discrete and continuous state sets obeying dynamical rules that enable application to swarming systems. The 2-state adaptive network contains a supercritical pitchfork bifurcation in the transition between ordered and disordered stationary solutions. We derive an adaptive network model that works on a continuous state set and apply it to swarming motion in both a mean eld and a moment closure approximation. In numerical solutions of the mean eld approximation the relation between the variance of the ordered stationary distributions and the system parameters is given by a square root function. Cauchy distributions form a good t to these steady state distributions, although they are not the analytic stationary solutions. We show that in numerical solutions of the moment closure approximation a bistable region is formed, in which the initial condition determines if the system ends up in an ordered or a disordered state. Further research could focus on nding the exact details of the corresponding subcritical pitchfork and saddle-node bifurcations and comparing the derived models to real-life swarming systems.

Twin deficits in CEEC economies: evidence from panel unit root tests

This paper analyses the relation between the external and government deficits in a panel of CEEC economies. We first assess by panel unit root tests whether the fiscal and external intertemporal budget constraints hold, and then examine the role of public and private expenditure in the dynamics of external indebtedness by panel regression. The results show that government deficit is a significant but relatively minor source of external imbalances, and that the external indebtedness of CEEC economies is sustainable.
Colonic Pseudo-obstruction: Contemporary Concepts and Practice

Acute colonic pseudo-obstruction is characterised by massive colonic distension without distal mechanical obstruction. It affects a wide variety of patients who often have multiple comorbidities, which makes studies on pseudo-obstruction difficult to perform and interpret. Few advances have been made in recent years in our understanding and management, which remain challenging. This article explores and provides interpretation of the key studies and concepts that have shaped our management of this condition.
