Effects of carbon on magnetic properties and magnetic entropy change of the LaFe11.5Si1.5 compound

Effects of the interstitial carbon atoms on the magnetic properties, especially on the magnetic entropy change, of the LaFe11.5Si1. 5 compound, have been studied. X-ray diffraction patterns reveal a monotonous increase of the lattice constant with the concentration of carbon, while the cubic NaZn13-type structure remains unchanged. The Curie temperatures TC of LaFe11.5Si1. 5Cy are ∼195, 225, and 241 K for y=0, 0.2, and 0.5, respectively, increasing with the increase of carbon concentration. The maximal magnetic entropy changes |ΔS| of LaFe11.5Si1. 5Cy at the respective TC under a magnetic field change of 0–5 T are ∼24.6, ∼22.8, and ∼12.7 J/kg K for y=0, 0.2, and 0.5, respectively, notably exceeding that of Gd (|ΔS| ∼9.8 J/kg K at TC=293 K). The |ΔS| of LaFe11.5Si1. 5C0.2 is nearly as giant as that of the parent alloy LaFe11.5Si1. 5 due to the first-order field-induced itinerant-electron metamagnetic transition that occurs in both compounds clearly observed for the LaFe11.5Si1. 5C0.5 compound. With the increase .
An analytical model to demonstrate the reliability of reconstructed ‘active longitudes’.

Photometric light curves show apparent spot concentrations separated by 180 degrees in longitude that are commonly referred to as ‘active longitudes’. These spot concentrations have been observed to change in strength resulting in the ‘flip‐flop’ effect. We use a simple analytical model to calculate the light curve of a star with an arbitrary spot pattern to show that ‘active longitudes’ are a likely consequence of the limited information content contained in a light curve. We also show that the same effects apply to heavily spotted stars.
Reply to comment on 'Spatial Coherence and Optical Beam Shifts'

In a comment, Wang, Zhu and Zubairy repeat their previous claim that the spatial Goos-H\"anchen (GH) shift happening at total internal reflection at a dielectric-air interface depends on the spatial coherence of the incident beam. This contradicts our theoretical and experimental findings. Here, we show that the apparent disagreement between their numerical simulations and our results occurs only in a parameter range where the concept of a spatial beam shift is invalid, and that therefore their claim is inapplicable. We clarify this by discussing two key issues.

Hemodynamic and Geometric Risk Factors for In-Stent Restenosis in Patients with Intracranial Atherosclerotic Stenosis

Methods Severe ICAS patients managed with percutaneous transluminal angioplasty and stenting (PTAS) were included in the retrospective cohort study and were divided into two groups according to whether ISR occurred at follow-up (ISR group and no-ISR group). Computational fluid dynamics models were built based on digital subtraction angiography before and after PTAS to simulate blood flow and quantify hemodynamic parameters. The associations between vessel geometry, hemodynamics, and ISR in ICAS patients were investigated. Results Among 39 patients, ISR occurred in seven patients (17.95%) after a mean follow-up period of 6.69 ± 3.24 months. Stenting decreased vessel angulation (51.11° [40.07°–67.27°] vs. 15.97° [0.00°–36.16°], P = 0.000) and vessel tortuosity (0.09 [0.06–0.13] vs. 0.01 [0.00–0.03], P = 0.000). Meanwhile, the translational pressure ratio (PR) dramatically increased (0.07 [0.00–0.31] vs. 0.62 [0.41–0.82], P = 0.000) with the wall shear stress ratio decreased (13.93 [8.37–40.30] vs. 2.90 [1.69–4.48], P = 0.000). In the multivariate analysis, smaller Δ tortuosity (P = 0.038) was independently associated with the occurrence of ISR, and smaller post-PTAS translesional PR was also a predictive factor of marginal significance (P = 0.059). Conclusion PTAS decreased vessel angulation, vessel tortuosity, and translesional wall shear stress ratio while it increased translesional pressure ratio (PR) dramatically in ICAS patients. Smaller Δ tortuosity was found to be a risk factor for ISR, and smaller post-PTAS translesional PR was also a predictive factor of marginal significance, indicating that both geometric and hemodynamic parameters played important roles in the occurrence of ISR after PTAS.

Non-fragile consensus control for nonlinear singular multi-agent systems: An event-triggered sampling scheme

This paper is devoted to the problem of non-fragile consensus control for a class of nonlinear singular multi-agent systems based on an event-triggered control strategy. To reduce the resource occupancy, a decentralized event-triggered sampling consensus control protocol for each agent is proposed, which does not require continuous communication among agents. Analysis of non-fragile consensus problem in the multi-agent systems is transformed into asymptotical stability issues of some lower dimensional subsystems via nonsingular transformation. Using the Lyapunov theory, sufficient conditions are obtained such that for all possible norm-bounded parameter variations in the protocol gains, the designed protocol can bring all agents’ states to a point of agreement. Furthermore, the corresponding protocol design method is also given. Numerical examples are included to illustrate the effectiveness of the derived results.
Analyzing Ground-Truth Data of Mobile Gambling Scams

With the growth of mobile computing techniques, mobile gambling scams have seen a rampant increase in the recent past. In mobile gambling scams, miscreants deliver scamming messages via mobile instant messaging, host scam gambling platforms on mobile apps, and adopt mobile payment channels. To date, there is little quantitative knowledge about how this trending cybercrime operates, despite causing daily fraud losses estimated at more than ${\$}$522,262 USD. This paper presents the first empirical study based on ground-truth data of mobile gambling scams, associated with 1,461 scam incident reports and 1,487 gambling scam apps, spanning from January 1, 2020 to December 31, 2020. The qualitative and quantitative analysis of this ground-truth data allows us to characterize the operational pipeline and full fraud kill chain of mobile gambling scams. In particular, we study the social engineering tricks used by scammers and reveal their effectiveness. Our work provides a systematic analysis of 1,068 confirmed Android and 419 iOS scam apps, including their development frameworks, declared permissions, compatibility, and backend network infrastructure. Perhaps surprisingly, our study unveils that public online app generators have been abused to develop gambling scam apps. Our analysis reveals several payment channels (ab)used by gambling scam app and uncovers a new type of money mule-based payment channel with the average daily gambling deposit of ${\$}$400,000 USD. Our findings enable a better understanding of the mobile gambling scam ecosystem, and suggest potential avenues to disrupt these scam activities.
Is there a role for controlled repositioning and mini-open primary osteoplasty in the management of unstable slipped capital femoral epiphysis?

ABSTRACT The management of unstable slipped capital femoral epiphysis is controversial with variable rates of avascular necrosis (AVN). Treatment options include in-situ stabilization, gentle/positional reduction and screw fixation and modified Dunn’s procedure (MDP). We present a technique of controlled repositioning (CRP) of the epiphysis to pre-acute slip stage, screw fixation and primary osteoplasty. Between 2015 and 2020, 38 unstable slips were treated in our institution. Of these, 14 underwent successful CRP and the rest were treated with MDP. All the 14 patients who had CRP and completed 1-year follow-up were included for this study. The head–neck angle (HNA) was measured at presentation and alpha angle, head–neck offset and AVN were assessed during follow-up. The average age was 14 years (9–18) and mean follow-up was 17.7 months (12–43). The average intraoperative flexion internal rotation before osteoplasty was −18.5° (−40° to −5°) which improved to +22.1° (+15° to +30°). The average preoperative HNA was 48.7° (34.1° to 70.7°) which improved to 18.4° (1.8° to 35.7°) post-operatively. At final follow-up, the average alpha angle and head–neck offset were 46.4° (30.9° to 64.6°) and 0.22 (0.09 to 0.96), respectively. The AVN rate in the CRP group was 7.1% compared with 20.8% in the MDP group, which was not significant (P = 0.383). Two patients had screw breakage. CRP, screw fixation and mini-open primary osteoplasty is a feasible treatment option in a subgroup of patients with unstable SCFEs. The limitation with this technique is that the final decision is made intraoperatively, and hence the patient and parents need to be counselled and consented appropriately. Level of evidence: Level IV—Case series.
Distributed adaptive dynamic event-based consensus control for nonlinear uncertain multi-agent systems

In order to tackle the real network constraints such as unknown state time-varying delays and limited communication resources, this article proposes a dynamic event-triggered control framework to satisfy the distributed consensus of heterogeneous strict-feedback multi-agent systems. Each follower agent is subject to nonlinear-in-parameter uncertainties regardless of satisfying the Lipschitz condition. Having considered the follower’s uncertainties, the adaptive neural network strategy is used to approximate uncertain functions. To further simplify the controller form, the minimal learning parameter technique is introduced to evade the updated information of the neural network weight vectors. Graph-based Lyapunov–Krasovskii functionals are utilized to handle the unknown state time-delays. A command filter dynamic event-triggered control scheme is then introduced to remove the complexity explosion regardless of global information of network. Different from the existing triggering strategies for the strict-feedback multi-agent systems, the proposed triggering mechanism is proved to include a positive bounded dynamical variable which results in the exclusion of the Zeno phenomenon and reducing the communication load in the controller to actuator channels. That can lead to the save of energy and communication resources, which are meaningful for employing the proposed scheme in the real practical applications. It is eventually proved that under the proposed approach, all the closed-loop network errors converge to a small neighborhood of the origin. A simulation example is finally given to show the effectiveness of the control scheme.

And there is a blue shift the absorption curves and red shift in fluorescence curves with the concentration increase. The quantum efficiency for liquid were larger than the solid matrix. Also, the stock shift increases the concentration in both liquid and solid samples.
Positive Influence Maximization in Signed Networks Within a Limited Time

With the rapid development of science and technology, influence maximization (IM) problem has been a hot research issue. There are positive and negative relations in social networks, so the problem of IM in signed networks has a wide range of applications. Moreover, the dissemination of information is usually time-sensitive in social networks. Therefore, in this article, we propose a problem about maximizing the positive influence in signed networks within a limited time (PIMST), further we utilize the influence path to calculate the influence probability and propose an algorithm that is based on forwarding index and inverted index. In the proposed algorithm, we first select candidate seed nodes by combining two effective heuristic methods. Then, we design an algorithm to get the activation probability between node pairs in social networks. At last, we devise a method which combining forward index, inverted index with the idea of cost delay, this method speed up the selection process of seed nodes. Finally, the experimental results on three social network datasets illustrate the effectiveness of our approach compared with other algorithms.
The Impact of Facebook Marketing on Customer-Based Brand Equity and Purchase Intention on Fashionwear Retail Industry in Sri Lanka

Purpose –This study focuses on examining the impact of Facebook marketing components on customer-based brand equity (CBBE) and purchase intention (PI). Design/methodology/approach – A conceptual model was developed based on the literature and related hypotheses were tested based on the responses of 390 Facebook (FB) fans of four leading fashion-wear retailers in Sri Lanka who have been selected on a random basis. The data was collected using an online survey and analyzed using the structural equation modeling. Findings- The results indicate that Facebook marketing has a strong impact on customer-based brand equity. The items entertainment, reputation and relationship remain for Facebook marketing construct to test its impact on customer-based brand equity. This finding helps to recognize the role of Facebook marketing from the strategic point of view, confirming its significant contribution in taking a brand to the next level. Furthermore, the direct impact of Facebook marketing on purchase intention was not significant and customer-based brand equity fully mediates the relationship between Facebook marketing and purchase intention. Originality –This research applies the Honeycomb model which is a rarely used model to identify the components of Facebook marketing. Hence, this can be identified as one of first this kind of research in Sri Lanka. Further, this study address Fashion-wear retail industry which another important but understudied sector in Sri Lanka. Implications – This article connects the consumers’ opinion on Facebook marketing. The findings of Facebook marketing on taking brand equity into next level will be useful for decision making in business organizations. The effective use of social media will reduce the promotional expenses. Further, the application of Honeycomb model shows the appropriate criteria for Facebook marketing and fill the gap of the unavailability of criteria for social marketing evaluation.
Understanding Inclusive Placemaking through the Case of Klostergata56 in Norway

Public participation and the placemaking approach are receiving continuously increasing attention and are therefore likely to become, in a near future, the norm of shaping our cities. They are instruments of local democracy, enabling citizens to stake a claim and exercise their influence on the city, repositioning them from recipients to active participants in this shaping. Research has shown that these democratic processes are the best way to ensure better physical environments, while also bringing social development. However, this attempt to shift from government to governance by power redistribution can at times pose a challenge to democracy, by repeating existing power relations between participating actors. If representation is not done right and communities are not equally engaged, the social benefits are at stake and issues of inclusion and exclusion arise. The need for assessment in this field is therefore highly relevant, but little progress has been done in developing measurable evaluation tools. This article is based on action research, following as a case study the process of co-designing Klostergata56, a small, underutilized public space in the Norwegian city of Trondheim. It presents a new framework of evaluating a participatory process, applied to the project to investigate its level of inclusion. Results of the study showed that the process had significant limitations to being inclusive to the expense of marginalized groups, due to unequal participation of stakeholders and differences in levels of nurtured social capital and civic trust. The challenges highlighted by the research make it possible to identify lessons for further processes to be more inclusive. Until such challenges are addressed, participatory placemaking will continue to be a trial-and-error process, therefore bound to repeat, at least to some extent, the inequality patterns present in a society.
Electromagnetic interactions of high energy cosmic ray muons

Electromagnetic interactions of high energy muons incident in the nearly horizontal direction at Durham, I98 ft. above sea level, have been studied by detecting electron-photon bursts produced in iron absorbers. Over the measured burst size range, bremsstrahlung and knock-on electron production were the predominant energy transfer processes. No divergence from accepted theory has been observed for energy transfer in the range 3 - 240 GeV. A second burst experiment has been performed to measure the spectra of nuclear-active particles incident at Durham in the nearly vertical direction. The observed spectra of both charged and neutral nuclear-active particles show a discontinuity at energies >100 GeV, which can be taken as support for the SU(_3) prediction that a protonis a tightly bound system of three charged quarks. This interpretation would indicate a quark mass of 10 GeV, and that high energy protons dissociate into their constituent quarks in about l8^ of their collisions above threshold (18OO GeV). A further implication isthat quarks interact strongly in the atmosphere, otherwise telescope detectors would have recorded an abundance of quarks. A decrease-2in the nucleon attenuation length from 127 gm. cm to a value ofp117 gm. cm(^-2) for sea level nucleon energies > 100 GeV would also account for the observed discontinuity.

A coupling construction for spin systems with infinite range interactions

Given a countable set of sites and a collection of flip rates at each site, we give a sufficient condition on the long-range dependancies of the flip rates ensuring the well-definedness of the corresponding spin system. This hypothesis has already been widely used since the interacting particle systems were introduced, but our construction brings a new insight to understand why it is natural. The process is first constructed as a limit of finite spin systems. Then we identify its generator and give a simple criterion for a measure to be invariant with respect to it.
Communicative and Supportive Strategies: A Qualitative Study Investigating Nursing Staff’s Communicative Practice With Patients With Aphasia in Stroke Care

This study aimed to provide detailed descriptions of the influences on the nursing staff’s communicative practices with patients with aphasia in the context of usual stroke care interactions, and secondly to explore the nursing staff’s use or non-use of supportive techniques, including the SCATM method. A qualitative design was chosen, combining field observations and semi-structured interviews. Inductive and deductive qualitative content analysis was used. The results showed that the nursing staff’s interactions with patients with aphasia were influenced by organizational and environmental influences, nurses’ roles and functions and supporting patients with aphasia in communication. The role of the nursing staff in caring for the psychosocial well-being of patients is deprioritised in favor of other tasks. If there is no time or culture for prioritizing time for conversing with patients and supporting their psychosocial well-being, communication-partner training like SCATM is likely hindered.
Exploit the Last Straw That Breaks Android Systems

The Android system services usually play a critical role in running multiple important tasks, and delivering seamless user experiences, e.g., conveniently storing user data. In this paper, we conduct the first systematic security study on the data storing process in Android system services, and consequently discover a novel class of design flaws (named Straw), which can lead to serious DoS (Denial-of-Service) attacks, e.g., permanently crashing the whole victim Android device.Then we propose a novel directed fuzzing based approach, called StrawFuzzer, to automatically vet all system services against the straw vulnerabilities. StrawFuzzer balances the tradeoff between path exploration and vulnerability exploitation. By applying StrawFuzzer on three Android systems with the latest security updates, we identified 35 unique straw vulnerabilities affecting 474 interfaces across 77 system services and successfully generated corresponding exploits, which can be used to conduct various permanent/temporary DoS attacks. We have reported our findings with suggestions for repairing the vulnerabilities to corresponding vendors. Up to now, Google has rated our vulnerability as high severity.
