Turbulent magnetic reconnection

The effects of turbulence on magnetic reconnection are investigated by two‐dimensional spectral method magnetohydrodynamic computations. The nonlinear evolution of the periodic sheet pinch configuration is studied as an initial value problem. Turbulence is initiated by including a low level of broadband fluctuations in the initial data. Nonlinear features of the evolution, appropriately described as turbulence, are seen early in the solutions and persist throughout the runs. Small‐scale, unsteady coherent electric current and vorticity structures develop in the reconnection zone, resulting in enhanced viscous and resistive dissipation. Unsteady and often spatially asymmetric fluid flow develops. Large‐scale magnetic islands produced by reconnection activity, undergo internal pulsations. Small‐scale magnetic islands, or ‘‘bubbles’’ develop near the reconnection zone, prodcing multiple X points. Large‐amplitude electric field fluctuations, often several times larger than the reconnection electric field, are produced by large island pulsations and by motion of magnetic bubbles. Spectral analysis of the fluctuations show development of broad band excitations, reminiscent of inertial and dissipation range spectra in homogeneous turbulence. Two‐dimensional spectra indicate that the turbulence is broadband in both spatial directions. It is suggested that the turbulence that develops from the randomly perturbed sheet pinchbears a strong resemblence to homogeneous magnetohydrodynamic turbulence, and that analytical theories of reconnection must incorporate these effects.
Effect of cantilever–sample interaction on piezoelectric force microscopy

We report on the evidence for the cantilever–sample (CS) capacitive force contribution to the piezoelectric force microscopy (PFM). In addition, we present that positioning of the tip near the edge of the sample surface can significantly reduce this spurious contribution for any combinations of tip cantilever and film. As proof of both the existence of CS interaction and its reduction, the domains formed by the application of voltage pulses through the tip are observed by PFM at two different positions, i.e., sample center and edge. In accordance with the model that a piezoresponse consists of a piezoelectric vibration of the film and an electrostatic force induced vibration of cantilever, the domain contrasts are characterized by dot structure in the amplitude and negligible contrast in the phase images when the tip is placed in the center of the sample surface. However, reducing the CS interaction by placing the tip near the sample edge yields domain contrasts showing ring structure in the amplitude and.
X-ray photoelectron spectroscopic study of KrF excimer laser nitrided InP surface

Nitridation of InP is performed by KrF excimer laser irradiation in an NH3 ambient. The N–In and N–P bonds are formed in the irradiated area in proportion to the number of laser pulses. The x-ray photoelectron spectroscopy spectra of the nitrided samples contain a small concentration of oxide components after aging in an air atmosphere than nonirradiated samples
Interpretation of Mariner 10 infrared observations of Venus

Abstract The infrared radiometer experiment on Mariner 10 measured limb darkening curves for Venus in two spectral intervals, one near 11 µm and the other near 45 µm. In this paper, these are analyzed in terms of the vertical opacity profile at each wavelength over a limited altitude range, approximately 60–80 km above the surface of the planet. Accurate multiple scattering calculations are used to show that both opacity profiles are consistent with a model containing a cloud of 1.1 µm radius sulphuric acid droplets, and a small amount of water vapor. Profiles of particle number density and humidity vs height are presented.
A NEW SAMPLE OF VERY MASSIVE STAR FORMING COMPLEXES IN THE SPITZER GLIMPSE SURVEY

We examine the 13 most luminous sources in the WMAP free–free map using the Spitzer GLIMPSE and Midcourse Space Experiment surveys to identify massive star formation complexes, emitting one-third of the Galactic free–free luminosity. We identify star-forming complexes (SFCs) by a combination of bubble morphology in 8 μm emission and radio recombination line radial velocities. We find 40 SFCs associated with our WMAP sources and determine unique distances up to 31. We interpret the bubbles as evidence for radial expansion. The radial velocity distribution for each source allows us to measure the intrinsic speed of a complex's expansion. This speed is consistent with the size and age of the bubbles. The high free–free luminosities, combined with negligible synchrotron emission, demonstrate that the bubbles are not driven by supernovae. The kinetic energy of the largest bubbles is a substantial fraction of that measured in the older superbubbles found by Heiles. We find that the energy injected into the interstellar medium by our bubbles is similar to that required to maintain turbulent motion in the gas disk inside 8 kpc. We report a number of new SFCs powered by massive (M* > 104 M☉) star clusters. We measure the scale height of the Galactic O stars to be h* = 35 ± 5 pc. We determine an empirical relationship between the 8 μm and free–free emission of the form F8 μm ∝ F2ff. Finally, we find that the bubble geometry is more consistent with a spherical shell rather than a flattened disk.
Distance Estimation Based on RSSI and Log-Normal Shadowing Models for ZigBee Wireless Sensor Network

In the last few years, a mobile wireless sensor and its application in wireless sensor network (WSN) are commonly used. Localization of a mobile sensor node is considered a critical issue in some WSN applications. In this paper, an outdoor environments experiment was carried out to measure the distance between the mobile node and the coordinator node in a simple point-to-point ZigBee WSN. The distance was determined based on the measured Received Signal Strength Indicator (RSSI) of the mobile node by the coordinator node. In addition, a Log-Normal Shadowing Model (LNSM) was derived for outdoor condition. Moreover, the parameters of the propagation channel such as standard deviation and a path loss exponent were estimated. The RSSI was measured and analysed for outdoor environments for a distance range 1-100 m. The measurements were carried out by using 2.4 GHz ZigBee wireless protocol based on XBee series 2 modules. The results disclosed that the mean absolute error (MAE) of 3.44 and 6.72 m for a distance range 0-65 m and 0-100 m, respectively. These results point that the LNSM is only suited for short distance.
Strategic perspective of error management the role of leadership and an error management culture: a mediation model

PurposeErrors are inevitable, resulting from the human condition itself, system failures and the interaction of both. It is essential to know how to deal with their occurrence, managing them. However, the negative tone associated with them makes it difficult for most organizations to talk about mistakes clearly and transparently, for fear of being harmed, preventing their detection, treatment and recovery. Consequently, errors are not managed, remaining accumulated in the system, turning into successive failures. Organizations need to recognize the inevitability of errors, making the system robust, through leadership and an organizational culture of error management. This study aims to understand the role of these influencing variables in an error management approach.Design/methodology/approachIn this paper methodology of a quantitative nature based on a questionnaire survey that analyses error management, leadership and the organizational culture of error management of 380 workers in Portuguese companies.FindingsThe results demonstrate that leadership directly influences error management and indirectly through the organizational culture of error management, giving this last variable a mediating role.Originality/valueThe study covers companies from different sectors of activity on a topic that is little explored in Portugal, but part of the daily life of organizations, which should deserve greater attention from directors and managers, as they assume a privileged position to promote and develop error management mechanisms. Error management must be the daily work of leaders. This study contributes to theoretical knowledge and business practice on error management.
OPTIMAL MEASUREMENT COMBINATIONS AS CONTROLLED VARIABLES

Abstract Self-optimizing control is a promising method for finding appropriate controlled variables. Recently, locally optimal methods were introduced for finding controlled variables by minimizing the worst-case loss. In this paper, we extend these local methods for average-case loss minimization. Furthermore, we present a method for finding optimal combinations of measurements for local self-optimizing control, for both of worst- and average-case loss minimization. The proposed results find the optimal solution efficiently, as compared to the available techniques like non-linear optimization or null space method. The usefulness of the results is demonstrated using an evaporator case study.
A weaker condition for the stability of nonsymmetric CNN's

In this paper, a new sufficient condition is given for the stability of a nonsymmetric CNN. This condition is less strict than that was given in Savaci and Vandewalle (1993). It also assures a stronger stability property than that was given in Chua and Roska (1990) as the existence of a stable equilibrium point is guaranteed. Therefore this condition allows more CNN types to be included into the class of stable CNN's. <<ETX>>
Anti-racist translingualism: investigating race in translingual scholarship in US Writing and rhetoric studies over the past decade

ABSTRACT In this exploratory study, we adopt corpus linguistic methods to quantify, contextualize and investigate race in translingual scholarship in US writing and rhetoric studies over the past decade. Results indicate that while race is mentioned minimally in the corpus, in instances where it is mentioned many scholars pay attention to intersectionality, language, colonial history, and power relations. Additionally, while there is a large representation of international students and newly-arrived immigrants in translingual scholarship in US writing and rhetoric studies over the past decade, domestic multilingual writers of color remain underrepresented. Situating translingualism in greater anti-racist initiatives, we discuss research and pedagogical implications that call for joint efforts from translingual scholars and practitioners to strive for linguistic justice and anti-racist translingual practices.
Opinion dynamics on a group structured adaptive network

Many models have been proposed to analyze the evolution of opinion structure due to the interaction of individuals in their social environment. Such models analyze the spreading of ideas both in completely interacting backgrounds and on social networks, where each person has a finite set of interlocutors.Moreover, the investigation on the topological structure of social networks has been the object of several analyses, both from the theoretical and the empirical point of view. In this framework a particularly important area of study involves the community structure inside social networks.In this paper we analyze the reciprocal feedback between the opinions of the individuals and the structure of the interpersonal relationships at the level of community structures. For this purpose we define a group based random network and we study how this structure co-evolves with opinion dynamics processes. We observe that the adaptive network structure affects the opinion dynamics process helping the consensus formation. The results also show interesting behaviors also in regards to the size distribution of the groups and their correlation with opinion structure.
Acceptance and Commitment Therapy for Social Anxiety Disorder in Adolescence: Preliminary Appraisal Based on a Case Study Approach

Social anxiety disorder (SAD) is characterized by marked and persistent fear in social situations in which one may be exposed and/or anticipates being exposed to external evaluation and in which embarrassment/humiliation may occur. Acceptance and Commitment Therapy (ACT) has been showing promising results in several disorders, including adult SAD. Considering this evidence and given that adolescence is typically the age of onset for SAD, we developed the ACT@TeenSAD, which is a manualized approach to adolescent SAD delivered via videoconference. It encompasses 10 weekly, 90-minute sessions targeting core pathological processes and fostering higher levels of psychological flexibility; it also includes two booster sessions. The current work illustrates the case conceptualization and therapeutic trajectory of a 17-year-old adolescent (Josie; pseudonym) with a 5-year history of SAD that underwent the ACT@TeenSAD. During the course of the intervention, Josie found purpose and learned life skills to cope with adversity, especially in socially relevant situations. This aligns with the pre- to post-intervention progress shown by Josie (using the Reliable Change Index), particularly in measures assessing acceptance, psychological inflexibility, and self-reported social anxiety. Josie’s case study gives preliminary evidence of the acceptability and feasibility of the ACT@TeenSAD, making it a helpful tool for therapists to become familiarized with. The current work also discusses the limitations of the intervention and presents practical challenges and suggestions thought to be useful for therapists.
MdWRKY120 Enhance Apple Susceptibility to Alternaria alternata

Alternaria alternata (A. alternata) is a common pathogen that greatly influences apples’ quantity and quality. However, chemical treatments produce increased health risks along with decreased food and environmental safety. Advancements in plant molecular biology, such as transgenic technology, have increased apple trees’ resistance to pathogens and have therefore attracted widespread attention. WRKY transcription factors are involved in abiotic and biotic stress regulation; however, their biological role in non-model plants such as apple, is still unknown. In this investigation, MdWRKY120 was isolated from the ‘GL-3′ apple to determine its function during Alternaria alternate infection. The MdWRKY120-GFP fusion protein was located in the nucleus. MdWRKY120 in yeast cells exhibited activating transcriptional activity, meaning it is a transcription activator. MdWRKY120 overexpression transgenic plants were more sensitive to A. alternata, while RNAi transgenic plants showed increased resistance to A. alternata. This investigation demonstrates that MdWRKY120 enhances the susceptibility of apples to A. alternata.
Numerical simulations on ion acoustic double layers

A comprehensive numerical study of ion acoustic double layers has been performed for both periodic and nonperiodic systems by means of one-dimensional particle simulations. For a nonperiodic system, an external battery and a resistance are used to model the magnetospheric convection potential and the ionospheric Pedersen resistance. It is found that the number of double layers and the associated potential buildup across the system increase with the system length. The potential jump . delta.phi/sub D/ across a single double layer is approximately e.delta.phi/sub D//T/sub e/roughly-equal1 and the distance between two consecutive double layers is typically 1000 Debye length, where e and T/sub e/ are the electronic charge and temperature. There is little interaction among double layers, and each double layer behaves almost independently of the others. The maximum increase of plasma energy through the enhanced resistance associated with double layer formation is found to be about 15% of the initial plasma energy for the parameters used in the simulations. The resistivity takes its maximum value at the instance when the double layers are just formed and then drops to almost zero afterwards, indicating the presence of a superconducting phase due to the formation of a quasistable Bernstein-Green-Kruskal type equilibrium. The equilibriummore » is, however, unstable with respect to the emission of ion acoustic solitons, and the double layers eventually decay as the solitons carry the energy away from the double layers propagating through a plasma toward the downstream direction. « less
The Interaction of Radiative and Dynamical Processes during a Simulated Sudden Stratospheric Warming

Abstract An analysis of a spontaneous sudden stratospheric warming that occurred during a 2-year integration of the Langley Research Center Atmospheric Simulation Model is presented. The simulated warming resembles observed “wave 1&rdquo warmings in the Northern Hemisphere stratosphere and provides an opportunity to investigate the radiative and dynamical processes occurring during the warming event. Isentropic analysis of potential vorticity sources and sinks indicates that dynamically induced departures from radiative equilibrium play an important role in the warming event. Enhanced radiative cooling associated with a series of upper stratospheric warm pools leads to radiative dampening within the polar vortex. Within the “surf zone” large-scale radiative cooling leads to diabatic advection of high potential vorticity air from aloft. Lagrangian area diagnostics of the simulated warming agree well with LIMS analyses. Dynamical mixing is shown to account for the majority of the decrease in the size of the.
Inpatient Geriatric Rehabilitation: Definitions and Appropriate Admission Criteria, as Established by Maltese National Experts

(1) Background: The importance of having an appropriate admissions system for geriatric rehabilitation is on the increase. However, the process of admitting patients to inpatient rehabilitation is a complex process. This is yet to be standardised across the European Union, as the approach to geriatric rehabilitation tends to vary from one Member State to another. (2) Objective: To discuss evidence-based practice with clinical experts, in order to define geriatric rehabilitation and admission criteria based on the Maltese population. (3) Method: The study entailed conducting four panel sessions using a purposive sample of thirteen local clinicians with extensive knowledge in clinical rehabilitation and healthcare management. A total of 48 items, based on the literature and clinical experience, were presented to the panel. Data analysis was done quantitatively and qualitatively, using IBM SPSS Statistics Version 24 and thematic analysis. (4) Results: The panel formulated a definition of rehabilitation, which shared common elements with the definition provided by the World Health Organization (WHO) and other sources/literature. The panel agreed on a list of eight criteria for appropriate inpatient geriatric rehabilitation admission in Malta. Consensus was also reached on: the need for a consultant-led multidisciplinary approach to assessment; the adoption of a standardised assessment processes for an equitable chance for all older adults assessed; the benefit of digital health in assessments; and the consideration that most patients would have some form of rehabilitation potential, depending on availability of resources. (5) Conclusion: Inpatient geriatric rehabilitation hospitals should have a unified strategy for rehabilitation services. The conclusions reached by the panel, could be useful in supporting the clinical evidence and establishing future rehabilitation guidelines and standards for inpatient rehabilitation.
Advances in bone tissue engineering

Bone tissue, as an important tissue structure of human body, plays an great role. Bone defects caused by trauma, infection and tumour resection are difficult to be repaired by themselves. Traditional methods for repairing bone defects include autograft and allograft. However, these methods have some problems such as limited source and immune rejection. In recent years, bone tissue engineering has attracted much attention due to its sufficient supply and no risk of infection, and is expected to replace traditional bone grafting. In bone tissue engineering, seed cells are cultured on scaffolds and transplanted into bone defects to repair bone defects. In this paper, the research progress of the three elements of bone tissue engineering, namely seed cells, scaffold materials and growth factors, was summarized by reading the literature, aiming to further promote the development of bone repair field.
An exact algorithm to minimize mixed-radix exclusive sums of products for incompletely specified Boolean functions

An exact algorithm for the synthesis of mixed polarity exclusive sum of product (ESOP) expressions for arbitrary size incompletely specified Boolean functions is presented. For more than four input variables, this problem has not been solved yet. A decision function H is constructed for a Boolean function f that describes all possible ESOP solutions to f. The function H plays for the ESOP minimization problem a role analogous to that of the Petrick function for the minimization of the inclusive sum of product expression problem of classical logic. Each product of literals that satisfies the function H corresponds to one ESOP solution of f. The algorithms to create and solve function H are presented. <<ETX>>

Background This study aimed to evaluate acute toxicity and oncological outcomes of breast cancer patients who underwent adjuvant radiotherapy (RT) with tomotherapy. Materials and methods The results of 114 patients who underwent adjuvant RT with Tomotherapy device between 17.08. 10–12.06. 2021 in Ankara Atatürk Training and Research Hospital and Ankara City Hospital were evaluated retrospectively. The primary endpoint of the study was acute adverse events, and the secondary endpoints were overall survival (OS) and disease-free survival (DFS). Results The results of 103 patients who met the inclusion criteria were analyzed. The median follow-up was 21 (range 1–125.8) months. Grade +3 esophagitis was not observed in any patient; no esophagitis was observed in 60 (58.3%) patients. Grade 3 dermatitis was observed in 3 (2.9%) patients. In addition, dermatitis was not observed in 47 (45.6%) patients. The relationship between chest wall volume and esophagitis development was statistically significant (p = 0.006; Z score: −2769). The median OS was 24.1 (range 1–128.5) and median disease-free survival was 21.1 (range 1–125.8) months. Five patients (4.9%) died and 9 patients (8.7%) relapsed. Local recurrence was observed in only 1 (1%) patient. There was a statistically significant correlation between OS and contralateral lung V20 dose [p < 0.001; Spearman Correlation Coefficient (SCC) −406) and heart mean dose (p < 0.001; SCC −370)]. There was a statically significant correlation between DFS and cN (p < 0.001); pN (p < 0.001); heart mean dose (p < 0.001; SCC −351); contralateral lung V5 dose (p = 0.041; SCC −213); contralateral lung V20 dose (p < 0.001; SCC −434). Conclusion Acute toxicity results show improvement in breast cancer adjuvant radiotherapy with helical tomotherapy.
