Stress-induced magnetic properties of PLD-grown high-quality ultrathin YIG films

Yttrium iron garnet (YIG:Y3Fe5O12) thin films were grown on (111) gadolinium gallium garnet (Gd3Ga5O12, GGG) substrates using pulsed-laser deposition under several different deposition and annealing conditions. X-ray diffraction measurements revealed that the crystallographical orientation of the YIG films is pseudomorphic to and the same as that of the GGG substrate, with a slight rhombohedral distortion along the surface normal. Furthermore, X-ray reciprocal space mapping evidenced that in-situ annealed YIG films during film growth are under compressive strain, whereas ex-situ annealed films have two different regions under compressive and tensile strain. The saturation magnetization ( 4 π M S) of the films was found to vary, according to the deposition conditions, within the range of 1350 to 1740 G, with a very low coercivity of H C < 5 Oe. From ferromagnetic resonance (FMR) measurements, we estimated the effective saturation magnetization ( 4 π M e f f) to be 1810 to 2530 G, which are larger than that of single crystalline bulk YIG (∼1750 G). Such high values of 4 π M e f f are attributable to the negative anisotropy field ( H U) that increases in size with increasing compressive in-plane strain induced in YIG films. The damping constant ( α G) of the grown YIG films was found to be quite sensitive to the strain employed. The lowest value of α G obtained was 2.8 × 10−4 for the case of negligible strain. These results suggest a means of tailoring H U and α G in the grown YIG films by the engineering of strain for applications in spintronics and magneto-optical devices.

The study should be replicated on large sample and in different hospitals setting to generalize the results
The beneficial effect of sulforaphane on platelet responsiveness during caloric load: a single-intake, double-blind, placebo-controlled, crossover trial in healthy participants

Background and aims As our understanding of platelet activation in response to infections and/or inflammatory conditions is growing, it is becoming clearer that safe, yet efficacious, platelet-targeted phytochemicals could improve public health beyond the field of cardiovascular diseases. The phytonutrient sulforaphane shows promise for clinical use due to its effect on inflammatory pathways, favorable pharmacokinetic profile, and high bioavailability. The potential of sulforaphane to improve platelet functionality in impaired metabolic processes has however hardly been studied in humans. This study investigated the effects of broccoli sprout consumption, as a source of sulforaphane, on urinary 11-dehydro-thromboxane B2 (TXB2), a stable thromboxane metabolite used to monitor eicosanoid biosynthesis and response to antithrombotic therapy, in healthy participants exposed to caloric overload. Methods In this double-blind, placebo-controlled, crossover trial 12 healthy participants were administered 16g of broccoli sprouts, or pea sprouts (placebo) followed by the standardized high-caloric drink PhenFlex given to challenge healthy homeostasis. Urine samples were collected during the study visits and analyzed for 11-dehydro-TXB2, sulforaphane and its metabolites. Genotyping was performed using Illumina GSA v3.0 DTCBooster. Results Administration of broccoli sprouts before the caloric load reduced urinary 11-dehydro-TXB2 levels by 50% (p = 0.018). The amount of sulforaphane excreted in the urine during the study visits correlated negatively with 11-dehydro-TXB2 (rs = −0.377, p = 0.025). Participants carrying the polymorphic variant NAD(P)H dehydrogenase quinone 1 (NQO1*2) showed decreased excretion of sulforaphane (p = 0.035). Conclusion Sulforaphane was shown to be effective in targeting platelet responsiveness after a single intake. Our results indicate an inverse causal relationship between sulforaphane and 11-dehydro-TXB2, which is unaffected by the concomitant intake of the metabolic challenge. 11-Dehydro-TXB2 shows promise as a non-invasive, sensitive, and suitable biomarker to investigate the effects of phytonutrients on platelet aggregation within hours.

Transient absorption measurement of laser-accelerated ion bunch radiolysis on sub-ps timescales

Modern laser-based accelerators for ions reach peak kinetic ion energies of > 100MeV, over 1MA of total beam currents with only a few picoseconds of bunch duration in close vicinity to the target at ≈ 1 Hz repetition rate and with a high controllability. Thus, the number of potential applications is growing rapidly. This raises a high interest in the processes of ion-matter-interactions in the energy deposition region of these ultra-intense particle bunches. In our recent experiments we investigated these interactions by single-shot time-resolved optical streaking of the energy deposition region of laser-accelerated proton bunches in liquid water. The absolute timing reference provided by the x-rays emitted from the laser-plasma-interaction and the sub-ps time resolution revealed that ionized electrons solvate > 20 ps delayed compared to experiments with lower deposited energy density. In this paper we discuss first approaches to explain these observations by micro-dosimetric considerations regarding the background molecules excitation of vibration states and polarization. This is highly relevant for applications, e.g. to understand the FLASH-effect in radio-biology. We further present the planned experiments at the Centre for Advanced Laser Applications where these phenomena will be investigated in more detail with advanced diagnostics.
Three-dimensional vibration of rotating functionally graded beams

The three-dimensional free vibration and time response of rotating functionally graded (FG) cantilevered beams are studied. Material properties of functionally graded beams are assumed to change gradually through both the width and the thickness in power-law form. The second-kind Lagrange’s equations are used in conjunction with the Ritz method to derive the comprehensive coupling dynamic equations for the axial, chordwise, and flapwise motions. The trial functions of deformations are taken as the products of the Chebyshev polynomials and the corresponding boundary functions. Nonlinear coupling deformations are considered to capture the dynamic stiffening effect due to the rotating motion. The influences of the material gradient index and rotational speed on modal characteristics are investigated by the state space method. The eigenvalue loci veering phenomena with modal conversions are exhibited. The time responses indicate that the deformations of rotating functionally graded beams are greatly affected by the material gradient index. It is shown that for large deformation problems, using Chebyshev polynomials is more efficient in computing precision and robustness than using other polynomials.
Induction of Hepcidin Expression in the Renal Cortex of Sickle Cell Disease Mice

In patients with sickle cell disease (SCD), chronic hemolysis and frequent blood transfusions cause iron overload and accumulation in the kidneys. The iron deposition is found in the renal cortex and correlates with the severity of hemolysis. In this study, we observed a significant accumulation of iron in the renal cortex of a mouse model of SCD, and assessed the expression of the proteins involved in maintaining renal iron homeostasis. Despite the intracellular iron accumulation, the levels of the transferrin receptor in the kidneys were increased, but the levels of the iron exporter ferroportin were not altered in SCD mice. Ferroportin is regulated by hepcidin, which binds to it and promotes its degradation. We found reduced serum hepcidin levels but increased renal hepcidin production in SCD mice. Furthermore, we observed significant macrophage infiltration and increased expression of intercellular adhesion molecule 1 in the endothelial cells of the kidneys in SCD mice. These observations correlated with elevated levels of proinflammatory cytokines IL-1β and IL-6, which can potentially stimulate hepcidin expression. Taken together, our results demonstrate that in individuals with SCD, a renal inflammation state induces renal hepcidin production that blocks the upregulation of ferroportin levels, resulting in dysregulation of iron homeostasis in the kidney and iron deposition in the renal cortex.
Analysis of a variational model for motion compensated inpainting

We study a variational problem for simultaneous video inpainting and motion estimation. We consider a functional proposed by Lauze and Nielsen [ 25 ] and we study, by means of the relaxation method of the Calculus of Variations, a slightly modified version of this functional. The domain of the relaxed functional is constituted of functions of bounded variation and we compute a representation formula of the relaxed functional. The representation formula shows the role of discontinuities of the various functions involved in the variational model. The present study clarifies the variational properties of the functional proposed in [ 25 ] for motion compensated video inpainting.
A Log Parsing Framework for ALICE O2 Facilities

The ALICE (A Large Ion Collider Experiment) detector at the European Organization for Nuclear Research (CERN) generates a substantial volume of experimental data, demanding efficient online and offline processing. To enhance the stability and reliability of the ALICE computing system, this study introduces an Artificial Intelligence-based logging system designed to detect, identify, and resolve issues through the analysis of system runtime information contained in logs. Existing online log parsing methods, however, often lack full automation and generality, relying instead on manual parameter definition and regular expressions that are better suited for static logs. In this study, we propose a novel and fully automated online log parsing framework for ALICE O2 (Online-Offline). To overcome key challenges, we employ the Term Frequency-Inverse Document Frequency (TF-IDF) algorithm to create ground truth, employ genetic programming to generate regular expressions, utilize the Artificial Bee Colony (ABC) algorithm for hyperparameter optimization, and implement a log template reduction algorithm to reduce similarity among log templates. Our framework’s effectiveness is validated through experiments on 5 benchmark log datasets and ALICE application logs, comparing its performance with the state-of-art online log parsing framework, Drain. The empirical results demonstrate the automated nature of our approach and its ability to achieve accurate parsing with high accuracy (i.e., 99.89% on the ALICE application log).
Assistance for Student Entrepreneurial Character Development through Compost Fertilizer Production Activities from Household Waste

Socialization activities on composting practices by utilizing household waste as an effort to take advantage of potential and protect the surrounding environment. This activity was carried out at Junior High School 2 Jatinangorwith the aim of creating a mindset for productive behavior and an entrepreneurial spirit from the production of compost which has high economic value. The method of implementing community service activities is carried out with training that produces skills, lecture methods, questions and answers, discussions, simulations and mentoring. The results of the activity revealed that the implementation of this composting activity was recognized by some students as an easy, simple, and beneficial practice for greening the environment. Socialization of making compost provides great benefits, namely an increase in students' knowledge about the benefits of organic waste residue as raw material for making compost. With this activity it is hoped that the impact will affect students' desire to always protect the environment and be able to apply it at home and in the environment around where they live in stages.
Implementation of a Peer Support Program to Increase Resilience in Nurse Managers in Acute Care Hospitals

Background: Nurse managers are at risk for experiencing stress and burnout. The peer support program was implemented to increase resilience among nurse managers. Methods: A one-group pretest and posttest design was employed to examine the impact of peer support on nurse manager resilience. The nurse managers participated in bi-weekly 30-minute peer sessions over 12 weeks. The Connor-Davidson Resilience Scale was utilized prior to and following the intervention along with demographic and satisfaction surveys. Results: There were six nurse managers who participated in the peer support program; however, only four completed both the preand post-survey. The peer support program intervention did not yield a significant result in increasing resilience levels among nurse managers (p = 0.832). Conclusion: Although the peer support intervention did not yield significant results, it shows promise as a needed intervention to address resilience in the nursing manager workforce. Based on the prevalence of stress and burnout among nurse managers, there is a continued need to utilize resilience as a mechanism to provide support. Further research would benefit with a larger sample size, a structured peer session format, and a controlled educational environment.
The Role of Brand Anthropomorphism In Shaping Brand Love and Brand Loyalty To European Car Consumers In Indonesia

This study will examine the influence of brand anthropomorphism and brand experience on brand love and its impact on brand loyalty with perceived price fairness as the moderation variable. The research uses a quantitative approach with a survey method. The sample in this study amounted to 250 European car users spread across DKI Jakarta, DI Yogyakarta, Central Java, East Java. The analysis model in this study will be divided into 3 stages of analysis. The first stage is multiple regression analysis, the second stage is simple regression analysis. The third stage of the moderation test with hierarchical moderated regression Brand anthropomorphism had a positive effect on the formation of brand love. Brand experience also has a positive and significant effect on brand love. Brand love has a positive effect on brand engagement. perceived price fairness does not moderate the relationship between brand love and brand engagement. For further research it is suggested to add subjective norm variables to this research model.
Medium-term and long-term renal function changes with direct oral anticoagulants in elderly patients with atrial fibrillation

Objective: Atrial Fibrillation (AF) and chronic kidney disease frequently coexist in the elderly. Warfarin-like drugs (WLDs) may be associated with a relatively greater decrease of estimated glomerular filtration rate (eGFR) as compared to direct oral anticoagulants (DOACs), but there is no evidence on the medium- and long-term changes. To further elucidate this issue in elderly patients with AF, we investigated the renal function deterioration in the two groups of the study (DOACs or WLDs). Patients and Methods: A total of 420 AF patients were enrolled (mean age: 77.0 ± 6.0 years; 136 on WLDs and 284 on DOACs). These patients underwent three eGFR measurements during the follow-up period. The between-arms difference of eGFR decline over time was investigated by Linear Mixed Models and group-based trajectory model analyses. Results: In the whole study cohort, after a median follow-up of 4.9 years (interquartile range: 2.7–7.0 years), eGFR decreased from 67.4 ± 18.2 to 47.1 ± 14.3 mL/min/1.73 m2 (p < 0.001). Remarkably, patients on DOACs experienced a significantly smaller eGFR decline than WLDs patients (−21.3% vs. −45.1%, p < 0.001) and this was true both in the medium-term (−6.6 vs. −19.9 mL/min/1.73 m2) and in the long-term (−13.5 versus −34.2 mL/min/1.73 m2) period. After stratification into five subgroups according to trajectories of renal function decline over time, logistic regression showed that DOACs patients had from 3.03 to 4.24-fold greater likelihood to belong to the trajectory with less marked eGFR decline over time than WLDs patients. Conclusion: Elderly patients with AF on treatment with DOACs had a relatively smaller decline of eGFR over time compared to those on treatment with WLDs. This is consistent with what was partly reported in the literature.
The influence of patient safety culture on incident reporting among health care professionals working in public hospitals in Addis Ababa, Central Ethiopia

Background: Patient safety is crucial to the quality of patient care and remains challenging for countries at all levels of development. There is a popular acknowledgement of the importance of establishing patient safety culture in healthcare organizations. Hospitals with a positive patient safety culture are transparent and fair with staff when incidents occur, learn from mistakes, and rather than blaming individuals, look at what went wrong in the system. Health care providers are willing to report the errors but, due to poor reporting system and culture of blame and shame, there exists struggle of disclosure of adverse events. Objective: To investigate the influence of patient safety culture on incident reporting behavior among health care professionals in public hospitals in Addis Ababa, central Ethiopia. Methods: Institution based cross-sectional study was conducted from March 15-20, 2017 at public hospitals in Addis Ababa. A total of 697health professionals were selected by simple random sampling method. Self-administered questionnaire was distributed to collect the data. A multivariate linear regression model was fitted. Then the effect of the socio-demographic variables and patient safety culture dimensions on the dependent variable “incident reporting behavior” was assessed using multiple linear regression analysis. Results: Among the participants, 20.4% never reported an incident, 13.1% reported rarely, 19.9% reported sometimes. Only 30.4 % reported incidents al ways. Feedback about error (β=0.136, p=0.008), management support for safety (β=0.28, p< 0.001), Non-punitive response to error, Supervisor/manager expectation and actions promoting patient safety (β=0.356, p< 0.001) and communication openness (β=0.170, p< 0.001) were the most predictive dimensions of patient safety culture for the incident reporting. Conclusions: Incident reporting behavior among health care professionals was very low. To increase the incident reporting behavior, placing priority on improving event reporting feedback mechanisms, communication regarding systems and process, giving priority by top-level hospital leadership and non-punitive response to errors.
Broadband spoof surface plasmon polariton couplers based on transmissive phase gradient metasurface

In this paper, we propose the design of broadband spoof surface plasmon polariton (SSPP) couplers based on transmissive phase gradient metasurfaces (TPGMs). Due to the large parallel phase gradient, transmitted waves through the TPGM are converted to driven surface waves (DSW). By placing the TPGM above a square patch array, the DSW can be coupled to an eigenmode SSPP in a broadband. High efficiency can be achieved since there is no initial reflection and SSPP decoupling effect in such SSPP couplers. A SSPP coupler was demonstrated in a microwave regime. Both the simulated and measured results show that the SSPP coupler can operate effectively in 7.0–9.9 GHz under normal incidence. Our finding may pave the way for broadband applications of SSPP.
Optimal dynamic promotion strategies in the multiple competing supply chains

ABSTRACT In this paper, the optimal decision problem is investigated for a class of dynamic promotions in the multiple competing supply chains. Here, the dynamic advertising model is allowed to be influenced by horizontal joint promotions (HJP) and vertical joint promotions (VJP). We extend the classical Nerlove–Arrow model by considering the effect of competitive manufacturer's VJP effort on brand goodwill. Also, the continuous-time demand is constructed with the effect of competitive retailer's VJP and HJP efforts. Based on the Hamilton–Jacobi–Bellman equation, the optimal HJP and VJP strategies of supply chain members and the optimal promotion cost sharing rate of each manufacturer are obtained under the Decentralized–Decentralized and Decentralized–Centralized structures, respectively. Subsequently, the comparison between the two structures shows that the optimal VJP and HJP efforts of supply chain members increase with their marginal profits and each manufacturer is willing to pay for the retailer's VJP effort level when the marginal profit of manufacturer exceeds the half of retailer's marginal profit. Numerical examples are provided to show the change of profit difference with parameters α and β under the different structures.
