PAPER 360 ° domain walls : stability , magnetic fi eld and electric current effects

The formation of 360°magnetic domainwalls (360DWs) inCo andNi80Fe20 thinfilmwires was demonstrated experimentally for different wirewidths, by successively injecting two 180° domain walls (180DWs) into thewire. For narrowwires (50 nmwide for Co), edge roughness prevented the combination of the 180DWs into a 360DW, and forwidewires (200 nm forCo) the 360DWwas unstable and annihilated spontaneously, but over an intermediate range of wirewidths, reproducible 360DW formation occurred. The annihilation and dissociation of 360DWswas demonstrated by applying amagneticfield parallel to thewire, showing that annihilation fieldswere several times higher than dissociation fields in agreementwithmicromagneticmodeling. The annihilation of a 360DWby current pulsingwas demonstrated. Magnetic domainwalls (DWs) in narrowwires provide a data token for devices such as racetrackmemory and logic gates [1–3]. DWdevicesmaintain the traditionalmerits ofmagnetic data storage including non-volatility and high density, but offer new functionality including fully electrical operation by using spin torque transfer to manipulate theDWs andmagnetoresistance to detect them. This can in principle enable faster switching speeds and lower energy consumption compared toDRAMs and other semiconductor devices [4]. Many proposedDW devices aremade fromnanowires containing 180DWs, where the orientation ofmagnetization rotates through 180° [5, 6]. An essential requirement forDWdevices is to be able to translateDWswithin the device, which can be accomplished using amagnetic field or a current pulse due to spin transfer torque [7, 8]. The 180DW in awirewith in-planemagnetization adopts a vortex or a transverse configuration, with transverseDWs favored in narrow or thinwires [6] as shown in the upper panel of figure 1(a). Closely spaced 180DWs in a nanowire interactmagnetostatically, and the attraction between two 180DWs of opposite core magnetization can lead to the formation of ametastable 360° domainwall (360DW), as shown in the lower panel offigure 1(a). 360DWs are also known as 1D skyrmions [9], an example of a class of topologically protected structures which are under intense study due to their stability and device applications [10]. 360DWshave been observed both in continuous ferromagnetic films [11] and in ferromagnetic nanostructures such as thinfilm rings or ellipses [12–14]. The orientation ofmagnetization rotates through 360°, and due to the opposite sense of coremagnetization in the two component 180DWs,magnetic flux closure reduces the stray field around the 360DW in a thinfilmwire compared to that of a 180DW [15]. 360DWs are not expected to be translated by an appliedfield, but instead can be dissociated or annihilated.However, micromagnetic simulations predict that a current can translate the 360DWvia spin torque transfer [15]. Moreover, instead ofWalker Breakdown as observed in 180DWs, a 360DW is predicted to undergo annihilation at a sufficiently high spin current density. Simulations predict that 360DWs of different chirality can befiltered OPEN ACCESS
Improving Active Queries with a Local Segmentation Step and Application to Land Cover Classification

Abstract. Active queries is an active learning method used for classification of remote sensing images. It consists of three steps: hierarchical clustering, dendrogram division, and active label selection. The goal of active learning is to reduce the needed amount of labeled data while preserving classification accuracy. We propose to apply local segmentation as a new step preceding the hierarchical clustering. We are using the SLIC (simple linear iterative clustering) algorithm for dedicated image segmentation. This incorporates spatial knowledge which leads to an increased learning rate and reduces classification error. The proposed method is applied to six different areas of the Vaihingen dataset.
Alleviation of Salt Stress in Seedlings of Black Glutinous Rice by Seed Priming with Spermidine and Gibberellic Acid

This study was carried out to elucidate the spermidine (Spd) and gibberellic acid (GA3) priming-induced physiological and biochemical changes responsible for induction of salinity tolerance in two rice (Oryza sativa L.) cultivars, namely â€˜Niewdam Gs. no. 00621â€™ (salt tolerant) and â€˜KKU-LLR-039â€™ (salt sensitive). The seeds of the two cultivars were primed separately with distilled water, 1 mM Spd or 0.43 mM GA3. Primed seeds were germinated and the resultant seedlings were hydroponically grown for 14 days before being exposed to salinity stress (150 mM NaCl) for 10 days. Seed priming with Spd or GA3 slightly improved salt-induced reductions in growth, anthocyanin and chlorophyll contents of the seedlings. Salt stress induced pronounced increases in Na+/K+ ratio, proline and H2O2 contents, particularly in the sensitive cultivar. The levels of these salt-sensitivity physiological indicators tended to be mitigated by priming with Spd and GA3. Salt-stressed seedlings grown from seeds primed with these growth regulators also possessed higher phenolic contents and greater antioxidant capacity than the control seedlings. Based on all growth and physiological data, Spd tended to be more effective than A3 in improving salt tolerance in both rice cultivars.
Effects of Linux Scheduling Algorithms on Mininet Network Performance

Software Defined Network (SDN) is considered a burgeoning technology in the field of computer networks particularly and in communication technologies in general. A promising architecture of SDN mainly depends on decoupling mechanisms of the control and management plane from the data forwarding plane in network device. Besides, the use of programmable interfaces between network layers. In another word, SDN uses open, flexible, and dynamic architecture that is defined through the use of different software's programming languages. Simulation and emulation network platforms play an important role in studying and evaluating different networks design and performance. Mininet is the most popular SDN platform. This research is concerned with the impacts of operating system scheduling algorithms used by Mininet emulator on network performance with different controllers and topologies types and sizes. It has been noted that network performance under PROC scheduling algorithm was better and more stable than those under CFS or RT scheduling algorithms. As well, when network topology be more complicated, i.e. contains a large number of switches and presence of loops, the network performance is worse than that with simple topology especially, this case is more worse with RT scheduling algorithm
Experimental-based simulated annealing for job shop scheduling problems with stochastic processing times

Job shop scheduling problem is widely known as one of the most difficult NP-Hard problems to solve and present efforts to solve the problems are mostly expressed in the form of heuristics. This thesis investigates the application of simulated annealing algorithm for solving job shop scheduling problem with stochastic processing times. Schedule quality is assessed based on the distribution of the schedule makespan, which is the maximum completion time of all jobs. The main idea is the integration of simulation into the simulated annealing algorithm. As such, variants of simulated annealing procedure for deterministic problems are first analyzed which are then extended to stochastic versions by incorporating simulation to evaluate schedules generated by the algorithms. Experimental results show that the stochastic variants provide an efficient tool in incorporating all the available distributional information on the processing times into the scheduling procedure. In addition, incorporating statistical tools such as the sampling methods enhance to certain extend the quality as well as the efficiency of the solutions. The performance of the simulated annealing variants is further investigated when three different temperature functions are proposed. The extensive computational tests and analysis on selected problem instances show the superiority of the proposed algorithms compared to some typical dispatching algorithms in high variability levels. Finally, the correlations between the expected makespan and the a-quantile of makespan are examined. The solutions obtained for low variability levels indicate that the two measures are perfectly correlated, and makespan distributions mostly follow the normal distributions, with few cases where they fail the normality tests. Although only stochastic processing times are considered in this thesis, the formulations and methodology can be extended to handle different objective functions as well as other kinds of uncertainties, such as uncertain arrival times, due dates and the handling of unpredictable machine breakdown and incorporation of new activities.

Evaluation of Social Risk in the Social Impact Investing

This study aimed at implementing the framework on social impact investing, focusing the attention on the identification, evaluation and measurement of social risk. In the last ten years, partly because of the financial crisis, there was an increasing interest in the world of social finance, especially in the theme of social impact investing. This theme attracts the attention not just of practitioner but also of research field in academia. However, the recent history of this theme, caused a lack of an adequate discussion about many aspects linked to SII regarding, in particular the evaluation and measurement of return and risk of this form of investment. Starting from this consideration this study follow three main passage. A formulation of a unique definition of social risk through a content analysis; an identification of main social risk factors, through a case study methodology; a construction of a social risk table score that is able to give a final quantitative value corresponding to the level of social risk of the program evaluated. This last step represent an innovation in the social finance evaluation topic, that could be considered an easy tool for practitioner and, in the same time, a first step to further research.
Diagnosis and treatment of ADHD: criteria used by different professional categories

Este estudio tuvo como objetivo investigar los criterios diagnosticos y propuestas de intervencion relacionados al TDAH de diferentes categorias profesionales en la ciudad de Natal – RN, Brasil. Participaron 34 profesionales seleccionados por conveniencia y a quienes se les realizo una entrevista semi-estructurada. Luego de la categorizacion de las informaciones se procedio al analisis descriptivo multidimensional de tipo Clusters. Se hizo evidente la division de la muestra total en otros dos grupos en relacion a las tres variables de mayor relevancia: educacion, numero de sesiones utilizadas en el diagnostico y uso de instrumentos formales. El Grupo 1, formado por medicos, se caracterizo por la utilizacion de dos o tres sesiones y por el uso de instrumentos y escalas formales. En el grupo 2, el numero promedio de sesiones fue superior a tres y todos los psicologos y la mayoria de los psicopedagogos no utilizaron escalas formales en el diagnostico. Se sugiere que la formacion academica determina las modalidades diagnosticas y de intervenciones utilizadas junto al TDAH.
CHAPTERR I I Transcriptionall modules in the developingg heart

T Fragment ss of regulator y DNA of cardiac genes drive reporter gene expression inn sometimes unexpecte d subdomains of the heart . These patterns have revealedd that the regulator y DNA of genes consist of distinct subfragment s (transcriptionall modules) that are active in different regions of the developing heart. In this review we give an overview of the activity of transcriptional moduless in vivo. Furthermore, we investigated the relation between the activity domainss of the transcriptional modules, the compartment s of the heart that weree added during evolution and the developmenta l patterning of the myocardium. The majority of the transcriptional modules show a domai n of activityy broader than the morphological boundar y of a cardiac compartment , andd sugges t that transcriptional modules largely respond to a patterning programm along the antero-posterio r axis.
Factors Affecting Adherence to Antihypertensive Medication: Results from a Rural Population Study in East of Iran

INTRODUCTION: Medication therapy is one of the most important interventions for the control of hypertension and its complications, but patient nonadherence to prescribed antihypertensive medication is a challenge. This study was conducted to measure medication adherence and examine its determinants in patients with hypertension in a rural population of Iran.METHODS: This cross-sectional study was conducted on 422 patients with hypertension covered by the healthcare network of Bajestan, Razavi Khorasan Province, Iran. Medication adherence was measured by using the Persian version of the 8 items Morisky Medication Adherence Scale (MMAS-8). The Chi-square test and Spearman’s correlation coefficient were used to examine the relationship between the determinants of medication adherence in SPSS.RESULTS: The mean age of the patients was 65.02±8.88 years. Of the total of 422 patients, 299 (70.9%) were female. Based on the MMAS-8, medication adherence was high in 39.6% of the patients, moderate in 10.9% and low in 49.5%. The variables that correlated significantly with the level of medication adherence included age (P=0.032), education (P=0.022), income (P=0.001), the satisfaction of patients-physician communication (P=0.006), physician based education (P= 0.003), occupation, time interval of physician’s consultation (P=0.001), medication regime complexity (P=0.001), medications meals frequency (P=0.001), side effects (P=0.081) duration of the disease (P=0.015), comorbidities (P=0.001), smoking (P=0.047), patient’s ability to read medication instruction (P=0.011), the patient’s beliefs about the effectiveness of medications (P=0.001) and the patient’s beliefs about the effectiveness of health system (P=0.001). The variables of gender (P=0.147), marital status (P=0.054), and distance problems to the health center (P=0.181) were not significantly correlated with the level of medication adherence.CONCLUSION: The results of the present study revealed a low medication adherence in half of the patients with hypertension due to various personal and socioeconomic determinants as well as factors associated with the health system, therapy-related factors, disease-related factors and patient-related factors. Purposeful interventions therefore appear essential to improving medication adherence in rural populations with a focus on the effect of each determinant of medication adherence.

The relevance of mathematics: Leaders and teachers as gatekeeper for Queensland senior calculus mathematics

The aim of the larger study, of which this paper is a part, is to investigate the decline in Year 10 male students’ participation in senior calculus mathematics courses at an independent boys’ school located in metropolitan Queensland. This paper draws on Sealey and Noyes’s (2010) relevance framework to conduct document analysis and interviews with leaders and teachers concerning the relevance of mathematics. In both cases results indicated that there was a limited understanding of relevance of mathematics.
Enhancement of phenylethanoid glycosides biosynthesis in Castilleja tenuiflora Benth: Shoot cultures with cell wall oligosaccharides from Fusarium oxysporum f. sp. lycopersici Race 3

Phenylethanoid glycosides (PhGs) are promising natural products for the treatment of chronic diseases because of their wide range of biological activities. Bio ic stress s pathoge attack (fungi) may stimulate the sy thesis of PhGs through activation of phenylalanine ammonia-lyase (PAL). Castilleja tenuiflora Ben h. (Orobanchaceae) in vitro cultures are alternative sources of PhGs, however in that conditions, cultures have a diminished synthesis of these compounds. To increase the yields of PhGs, the identifica ion of fact rs affec ng their biosynth sis is required. Here, we show that elicitation with cell wall oligosaccharides (CWOs) from Fusarium oxysporum f. sp. lycopersici race 3 (Hyphomycetes) stimulates biosynthesis of PhGs by increasing the activity of PAL. Upon elicitation with CWOs (13 μg/mL) the production of PhGs was enhanced by 5-fold compared with untreated control. The maximum PAL activity in shoots cultured under CWOs elicitation were also increased. Elicitation did not affect the shoot growth (length and biomass) but induced chlorosis, and delayed root formation of C. tenuiflora shoots. Our results demonstrate that elicitation with CWOs increases PhGs biosynthesis in C. tenuiflora shoot culture.
Structural and Morphological Characterization of Micro and Nanofibers Produced by Electrospinning and Solution Blow Spinning: A Comparative Study

Nonwoven mats of poly(lactic acid) (PLA), poly(ethylene oxide) (PEO), and poly(e-caprolactone) (PCL) were prepared at a nano- and submicron scale by solution blow spinning (SBS) and electrospinning in order to compare crystalline structure and morphology developed by both processes during fiber formation. Polymer solutions were characterized by rheometry and tensiometry. Spun fibers were characterized by several analytical steps. SEM analyses showed that both solution blow spun and electrospun fibers had similar morphology. Absence of residual solvents and characteristic infrared bands in the solution blow spun fibers for PLA, PCL, and PEO was confirmed by FTIR studies. XRD diffraction patterns for solution blow spun and electrospun mats revealed some differences related to distinct mechanisms of fiber formation developed by each process. Significant differences in thermal behavior by DSC were observed between cast films of PLA, PCL, and PEO and their corresponding spun nanofibers. Furthermore, the average contact angles for spun PLA and PCL were higher than for electrospun mats, whereas it was slightly lower for PEO. When comparing electrospun and solution blow spun fibers, it was possible to verify that fiber morphology and physical properties depended both on the spinning technique and type of polymer.
Experimental characterization of ultraviolet radiation of air in a high enthalpy plasma torch facility

During atmospheric reentry, a plasma is formed ahead of the surface of the vehicle and the excited particle present in the plasma produces radiative heating fluxes to the surface of the vehicle. A high-temperature air plasma torch operating at atmospheric pressure was used to experimentally reproduce atmospheric reentry conditions. A high-resolution and absolute intensity emission spectrum (full width at half maximum (FWHM) = 0.064 nm) was obtained from 200 to 450 nm and then compared with computational results provided by the SPECAIR code [1]. This paper discusses the comparison of the two spectra over this wavelength range in order to confirm the validity of the calculation and provide direction to improve the calculated spectrum.
Effects of the Form of Government and Property Tax Limits on Local Finance in the Context of Revenue and Expenditure Simultaneity

This paper examines the impact of the form of government and state‐imposed property tax limits on municipal finance. We suggest that municipal revenues and expenditures are determined concurrently and estimate revenue and expenditure functions as simultaneous equations. We use the instrumental variable approach and fixed effects to address revenue and expenditure endogeneity. By testing the model on a cross‐section of rich municipal data for fiscal year 2002, we find evidence that revenues and expenditures are simultaneously determined, that potentially binding state‐imposed property tax limits effectively restrict local revenues and that the form of government is a significant predictor of local expenditures.
Title The Hospitals/Residents Problem with Lower Quotas

The Hospitals/Residents problem is a many-to-one extension of the stable marriage problem. In an instance, each hospital specifies a quota, i.e., an upper bound on the number of positions it provides. It is well-known that in any instance, there exists at least one stable matching, and finding one can be done in polynomial time. In this paper, we consider an extension in which each hospital specifies not only an upper bound but also a lower bound on its number of positions. In this setting, there can be instances that admit no stable matching, but the problem of asking if there is a stable matching is solvable in polynomial time. In case there is no stable matching, we consider the problem of finding a matching that is “as stable as possible”, namely, a matching with a minimum number of blocking pairs. We show that this problem is hard to approximate within the ratio of (|H |+|R|) for any positive constant ǫ where H and R are the sets of hospitals and residents, respectively. We then tackle this hardness from two different angles.
