Ultrafast Electron-Electron Scattering in Metallic Phase of
2H−NbSe2
Probed by High Harmonic Generation
Authors: Takeda K. S. , Uchida K. , Nagai K. , Kusaba S. , Takahashi S. , Tanaka K. 
Published: May 2024

Electron-electron scattering on the order of a few to tens of femtoseconds plays a crucial role in the ultrafast electron dynamics of conventional metals. When mid-infrared light is used for driving and the period of light field is comparable to the scattering time in metals, unique light-driven states and nonlinear optical responses associated with the scattering process are expected to occur. Here, we use high-harmonics spectroscopy to investigate the effect of electron-electron scattering on the electron dynamics in thin film 2H−NbSe2 driven by a mid-infrared field. We observed odd-order high harmonics up to 9th order as well as a broadband emission from hot electrons in the energy range from 1.5 to 4.0 eV. The electron-electron scattering time in 2H-NbSe2 was estimated from the broadband emission to be almost the same as the period of the mid-infrared light field. A comparison between experimental results and a numerical calculation reveals that competition and cooperation between the driving and scattering enhances the nonperturbative behavior of high harmonics in metals, causing a highly nonequilibrium electronic state corresponding to several thousand Kelvin.

Frustration-induced quantum criticality in Ni-doped CePdAl as revealed by the
µSR
technique
Authors: Ishant I. , Shiroka T. , Stockert O. , Fritsch V. , Majumder M. 
Published: May 2024

In CePdAl, the 4f moments of cerium arrange to form a geometrically frustrated kagome lattice. Due to frustration, in addition to Kondo and Ruderman-Kittel-Kasuya-Yosida interactions, this metallic system shows a long-range magnetic order (LRO) with a TN of only 2.7 K. Upon Ni doping at the Pd sites, TN is further suppressed, to reach zero at a critical concentration xc≈0.15. Here, by using muon-spin relaxation and rotation (µSR), we investigate CePd1−xNixAl at a local level for five different Ni concentrations, both above and below xc. Like the parent CePdAl compound, for x=0.05, we observe an incommensurate LRO, which turns into a quasistatic magnetic order for x=0.1 and 0.14. More interestingly, away from xc, for x=0.16 and 0.18, we still observe a non-Fermi-liquid (NFL) regime, evidenced by a power-law divergence of the longitudinal relaxation at low temperatures. In this case, longitudinal field measurements exhibit a time-field scaling, indicative of cooperative spin dynamics that persists for x>xc. Furthermore, like the externally applied pressure, the chemical pressure induced by Ni doping suppresses the region below T*, characterized by a spin-liquid-like dynamical behavior. Our results suggest that the magnetic properties of CePdAl are similarly affected by the hydrostatic and the chemical pressure. We also confirm that the unusual NFL regime (compared with conventional quantum critical systems) is due to the presence of frustration that persists up to the highest Ni concentrations.

Socio-cognitive mindfulness is a well-being booster: a serial mediation model to test the mindfulness reappraisal hypothesis with managers
Authors: Junça Silva Ana 
Published: May 2024

PurposeThe purpose of this study was to investigate the relationship between mindfulness and two types of well-being, namely subjective and psychological well-being, particularly in a managerial context. The mindfulness-to-meaning theory (MMT) suggests that the practice of mindfulness might lead individuals to reevaluate and find greater meaning in their experiences, ultimately contributing to increased well-being. Accordingly, we argue that mindfulness boosts well-being because it may potentially lead managers to reappraise what surrounds them, making them experience more frequent positive affect.Design/methodology/approachA two-wave survey with a two-week interval was used to gather quantitative data. An overall sample of 1,260 managers with and without experience with mindfulness took part in the study.FindingsStructural equation modeling showed that mindfulness had a direct and positive relationship with both subjective and psychological well-being. Furthermore, both processes – positive reappraisal and positive affect – mediated the path from mindfulness to both forms of well-being.Practical implicationsThe findings emphasize the importance of creating training strategies that develop managers’ ability to positively reappraise daily events and occurrences, which may trigger more frequently positive affective experiences. Therefore, promoting mindfulness training at the workplace may develop mindful employees, especially by working on specific strategies, such as positive reappraisal, which may be a promising empirical-based strategy to enhance well-being.Originality/valueThis study adds knowledge about how mindfulness can contribute to well-being and contributes to expanding the mindfulness-to-meaning theory by adding positive affective experiences as an additional mechanism in the relationship between mindfulness and well-being. Specifically, it demonstrates that the practice of mindfulness helps managers to positively reappraise their surroundings, which results in more frequent experiences of positive affect.

Human centered digital transformation in travel: a horizon 2050 paper
Authors: Inversini Alessandro 
Published: May 2024

Purpose
The impact of digital technology in the wider travel field has been substantial and significant, changing both the competitive landscape of businesses and the behavior of travelers. However, we are now on the cusp of new digital developments encompassing cloud computing, blockchain, internet of things (IoT) and above all, artificial intelligence (AI), which are predicted to disrupt the business and consumer sides of several industries – travel included. This study aims to frame this upcoming digital transformation in travel within a human-centered approach where the critical understanding of digital humanism principles will enrich social scientists’ research agenda in the coming years.

Design/methodology/approach
The viewpoint follows a structure based on (i) setting the scene for the rise of digital transformation, (ii) the historical perspective on digital transformation in travel, (iii) the pandemic’s impact and (iv) future development and research agenda.

Findings
It is only by fostering a human-centered digital transformation perspective that social science researchers in travel can realize the “high-tech for high-touch” promise of fostering a human-to-human encounter empowered and possibly hampered, by digital technologies. This work proposes to start from the concepts of digital technology control, participation, education and ethics to design a research agenda with a 2050 horizon.

Originality/value
This work has been designed to shift the attention of researchers toward a human-centered digital transformation approach to reflect on the human-machine relationship for a better society. Due to its inner characteristics the travel field can foster a reflection on this topic by reaffirming the centrality of human beings and their authorship in the travel product creation.

Published: May 2024

AbstractCTCE‐9908, a CXC chemokine receptor 4 (CXCR4) antagonist, prevents CXCR4 phosphorylation and inhibits the interaction with chemokine ligand 12 (CXCL12) and downstream signalling pathways associated with metastasis. This study evaluated the in vitro effects of CTCE‐9908 on B16 F10 melanoma cells with the use of mathematical modelling. Crystal violet staining was used to construct a mathematical model of CTCE‐9908 B16 F10 (melanoma) and RAW 264.7 (non‐cancerous macrophage) cell lines on cell viability to predict the half‐maximal inhibitory concentration (IC50). Morphological changes were assessed using transmission electron microscopy. Flow cytometry was used to assess changes in cell cycle distribution, apoptosis via caspase‐3, cell survival via extracellular signal‐regulated kinase1/2 activation, CXCR4 activation and CXCL12 expression. Mathematical modelling predicted IC50 values from 0 to 100 h. At IC50, similar cytotoxicity between the two cell lines and ultrastructural morphological changes indicative of cell death were observed. At a concentration 10 times lower than IC50, CTCE‐9908 induced inhibition of cell survival (p = 0.0133) in B16 F10 cells but did not affect caspase‐3 or cell cycle distribution in either cell line. This study predicts CTCE‐9908 IC50 values at various time points using mathematical modelling, revealing cytotoxicity in melanoma and non‐cancerous cells. CTCE‐9908 significantly inhibited melanoma cell survival at a concentration 10 times lower than the IC50 in B16 F10 cells but not RAW 264.7 cells. However, CTCE‐9908 did not affect CXCR4 phosphorylation, apoptosis,\ or cell cycle distribution in either cell line.

AbstractIntroductionThe aim of this study was to investigate changes in echocardiographic right ventricular (RV) indices in relation to the degree of fluid accumulation between hemodialysis sessions, evaluated according to the recommended threshold of interdialytic‐weight‐gain corrected for dry weight (IDWG%).MethodsA post‐hoc analysis was performed using data from 41 maintenance hemodialysis patients. Patients were divided into a higher (>4.5%) and a lower (<4.5%) IDWG% group and underwent an echocardiographic assessment at the start and the end of the 3‐day and the 2‐day interdialytic interval.ResultsRV systolic pressure (RVSP) increments were more pronounced in the higher compared to the lower IDWG% group (16.43 ± 5.37 vs. 14.11 ± 13.38 mm Hg respectively, p = 0.015) over the 3‐day interval, while changes in RV filling pressures, did not differ significantly between the groups (p = 0.84).ConclusionsDuring the 3‐day interdialytic interval, pulmonary circulation is particularly overloaded in patients with fluid accumulation higher than the recommended thresholds, as evidenced by higher RVSP elevations.
Expanding the applications of the standardized streamflow index through regionalization
Authors: Anderson Elliot S. , Schilling Keith E. 
Published: May 2024

AbstractThe Standardized Streamflow Index (SSI) has frequently been used to quantify drought by comparing periods of streamflow against a river's historical values. This study expands upon previous SSI methodologies by creating a more flexible, regionalized version of the metric for Iowa, a Midwestern state located in the central United States. Five drought regions were developed for Iowa that largely correspond to the state's Major Land Resource Areas. Several United States Geological Survey gauges were identified within each drought region and streamflow data were used to calculate daily water yields from 1960 to the present. SSI values calculated for both individual river sites and the entire drought region provide insights into the relative dryness of Iowa watersheds over the past several decades. The SSI methodology can be used to evaluate river dryness with limited data records and water yields of specific streams can be compared to each other and across the overall region. This study demonstrates the potential for developing versions of the SSI that enable real‐time calculations at a daily scale at locations with limited historical streamflow data. The new SSI metric may be a valuable tool for decision‐makers as state and federal agencies continue to identify and manage drought.

Published: May 2024

AbstractIntroductionLong‐read whole genome sequencing like Oxford Nanopore Technology, is increasingly being introduced in clinical settings. With its ability to simultaneously call sequence variation and DNA modifications including 5‐methylcytosine, nanopore is a promising technology to improve diagnostics of imprinting disorders.MethodsCurrently, no tools to analyze DNA methylation patterns at known clinically relevant imprinted regions are available. Here we present NanoImprint, which generates an easily interpretable report, based on long‐read nanopore sequencing, to use for identifying clinical relevant abnormalities in methylation levels at 14 imprinted regions and diagnosis of common imprinting disorders.Results and conclusionNanoImprint outputs a summarizing table and visualization plots displays methylation frequency (%) and chromosomal positions for all regions, with phased data color‐coded for the two alleles. We demonstrate the utility of NanoImprint using three imprinting disorder samples from patients with Beckwith‐Wiedemann syndrome (BWS), Angelman syndrome (AS) and Prader‐Willi syndrome (PWS).

AbstractObjectiveObesity has been associated with chronic low‐grade systemic inflammation. This study aimed to investigate the relationship of pentraxin‐3 (PTX‐3) with anthropometric measurements, dietary content and physical activity level in children.DesignA matched group study.PatientsThis study was conducted with 91 children aged 6–17 years, divided into two groups: “non‐obese group” (Body Mass Index Standard Deviation Score [BMI SDS] <95th percentile) and “obese group” (BMI SDS ≥95th percentile).MeasurementsPlasma PTX‐3 levels.ResultsThe mean age of 91 children included in the study was 12.34 ± 2.86 years. Plasma PTX‐3 levels were significantly higher in obese children (p = .028). No significant correlation was found between BMI SDS and plasma PTX‐3 values, but a weak positive correlation was found when physical activity level was controlled (r = .176, p = .049). In addition, it was found that fat mass was a partial mediator of plasma PTX‐3 level, and an increase in the amount of subcutaneous adipose tissue negatively affected plasma PTX‐3 level. Plasma PTX‐3 level showed a weak positive correlation (r = .223, p = .017) with physical activity score and dietary polyunsaturated fatty acid intake, while a weak negative correlation with neutrophil‐to‐lymphocyte ratio. One unit increase in physical activity score or polyunsaturated fatty acid level caused 0.730 and 2.061 unit increases in plasma PTX‐3 level, respectively; while one unit increase in dietary fat intake caused 0.413‐unit decrease.ConclusionThere was an indirect relationship between the amount of subcutaneous adipose tissue and PTX‐3 level. The results of our study suggested that plasma PTX‐3 was associated with lower levels of inflammation in children.

Is imagination really more important than knowledge? In this invited article, I will briefly describe two innovations—OrganJet and Nudge Videos—that I have implemented in the US Transplantation System that have extended the lives of many.
Emigrant voyages from the UK to North America and Australasia, 1853–1913
Authors: Hatton Timothy J. 
Published: May 2024

AbstractStudies of the determinants of emigration from Europe from 1850 to 1913 include the gains to migrants but often neglect the costs. One component of those costs is earnings forgone on the voyage. In this paper, I present new data on the voyage times for emigrants from the UK traveling to the United States and to Australia. Between 1853–7 and 1909–13 the voyage time from Liverpool to New York fell from 38 days to just 8 days (or 79 per cent). Over the same years, the emigrant voyage to Sydney fell by more in absolute terms, from 105 days to 46, but by less in relative terms (56 per cent). Differences in profiles of travel times are explained with a focus on the transition from sailing to steam ships and (for Australia) the use of the Suez Canal. Data series for fare prices and foregone wage costs during transit are combined to create new series on the ‘total’ cost of emigrant voyages. Econometric analysis of the determinants of UK emigration to the United States, Canada, and Australia supports the view that time costs mattered.

AbstractAimThis study investigates the psychopathological characteristics of a sample of individuals at ultra‐high risk for psychosis with and without comorbid attention‐deficit hyperactivity disorder (ADHD).MethodsTwenty‐eight subjects (aged 13–21 years; 13 females) with attenuated psychosis syndrome (APS) were recruited in a cross‐sectional study and divided into two groups, each with 14 patients, according to the presence or absence of ADHD.ResultsThe APS group showed a significantly higher prevalence of negative symptoms than the APS + ADHD group. Other characteristics investigated (positive symptoms, aberrant salience, psychotic‐like experiences and prodromal symptoms) did not differ between groups.ConclusionsThe different profiles of negative symptoms in the APS with or without ADHD might suggest the presence of a specific subtype among individuals at ultra‐high risk for psychosis. Longitudinal studies with larger samples will provide information about the role of negative symptoms in determining conversion to full psychosis in those people with ‘pure’ APS and those with APS + ADHD.

AbstractA novel glass additive of 10Bi2O3‒5Li2O‒7.5Na2O‒7.5K2O‒21Nb2O5‒20.5SiO2‒10.5BaO‒11SrO‒4.5Al2O3‒0.5La2O3‒2TiO2 was melted to improve the energy‐storage properties of (Ba0.94Li0.02La0.04)(Mg0.04Ti0.96)O3 (BLLMT) ceramics (BLLMT‒x wt% G), which overcomes the paradox between polarization and voltage endurance. The dielectric constant and resistance of BLLMT ceramics are improved by glass modification, while the grain size decreases. Consequently, excellent breakdown strength of 565.9 kV/cm is obtained, and the difference between maximum polarization and remnant polarization reaches up to 22.14 µC/cm2. Weibull distribution and finite element simulation prove that grain boundary density, grain size, resistance, and bandgap width have significant effects on the breakdown strength. Finally, outstanding energy‐storage density of 4.82 J/cm3 is obtained at x = 2, accompanied with an excellent pulse discharged energy density of 3.42 J/cm3, current density of 1226.12 A/cm2, and power density of 337.19 MW/cm3. Excellent temperature stability is gained with the variation of the pulse discharged energy density less than 10% at 20°C‒140°C. The outstanding pulse energy‐storage parameters are related to phase structure, small grain size, high grain boundary density, formation of liquid phase, increased ceramic resistance, and destroyed long‐range ordered ferroelectrics. This work provides a novel idea for fabricating glass to obtain excellent energy‐storage performance and promotes practical application of BaTiO3 ceramics.
