Abstract

Objectives
Past studies showed that intergenerational contact is beneficial in improving attitudes toward older people. To date, however, research on the benefits of contact with older adults focused on younger adults (intergenerational contact), overlooking the effects for older adults (contact with same-age peers). In this study, we investigated the association between contact with older adults and views of the self in old age in a domain-specific way among younger and older adults.

Methods
The sample (n = 2,356) comprised younger (39–55 years) and older (65–90 years) adults who participated in the aging as future study and were from China (Hong Kong and Taiwan), the Czech Republic, Germany, and the United States. We used moderated mediation models for data analysis.

Results
Contact with older adults was related to more positive views of the self in old age and this effect was mediated by more positive stereotypes of older people. These relations were stronger for older adults. Beneficial effects of contact with older adults emerged mostly in the domains of friends and leisure, but less in the family domain.

Discussion
Having interactions with other older adults may help favorably shape how younger adults and particularly older adults view their own aging, especially in relation to friends and leisure activities. From the perspective of older adults, having regular contacts with other older adults may increase the heterogeneity of exposure to different aging experiences, thus encouraging the formation of more differentiated stereotypes of older people and of their views of themselves in old age.

SUMMARYThe 2008 Wenchuan earthquake, which occurred on the eastern edge of the Tibetan Plateau, produced significant time-dependent post-seismic deformation in the northeastern Tibetan Plateau. To explore the spatio-temporal evolution of crustal deformation and its impact on nearby active faults due to the Wenchuan earthquake, we first solve the velocity fields, strain rates and slip rates of the major faults at different stages of the earthquake cycle, based on GPS observations spanning approximately 10 yr before and after the Wenchuan earthquake. The results show that: (a) during the late interseismic phase, the GPS velocity fields relative to the Sichuan basin and strain rates near the Longmenshan fault (the seismogenic fault of the Wenchuan earthquake) are insignificant in magnitude, and the geodetic slip rates of the major faults are in good agreement with geological investigations; (b) After the Wenchuan earthquake, post-seismic deformation on both flanks of the causative Longmenshan fault is asymmetrically distributed, with significant deformation distributed between the Longmenshan fault and the Longriba fault. The post-seismic deformation decreases with increasing distance away from the Longmenshan fault. Furthermore, geodetic slip rates for the major active faults at the early post-seismic stage differ significantly from those at the late interseismic stage; (c) The crustal deformation in the northeastern Tibetan Plateau is generally small during the late interseismic phase, but it increases significantly during the early post-seismic stage and begins to decrease again as it progresses to the second post-seismic stage. We speculate that this kinematic evolution of crustal deformation is ascribed to that the Longmenshan fault was in a locking state during the late interseismic period, whereas the Longmenshan fault is no longer locked after the Wenchuan earthquake, and thus the marked post-seismic deformation occurred in the epicentral and its surrounding area. Then, the post-seismic deformation becomes weaker with time lapse, and generally the crustal deformation begins to slowly recover to the pre-seismic level. Using a forward model, we test whether post-seismic deformation caused by viscoelastic relaxation of the lower crust 4 yr after the Wenchuan earthquake can explain the observed spatio-temporal pattern of the crustal deformation. We find that this mechanism can account for the evolutionary pattern of crustal motion in the Songpan-Ganzi block east of the Longriba fault in central-east Tibet and central-eastern and southern regions of the West Qinling-Songpan Tectonic Syntaxis in east Tibet 4 yr after the Wenchuan earthquake. Moreover, the post-seismic viscoelastic relaxation of the Wenchuan earthquake is the main cause of loading rate variations of primary faults in the early post-seismic stage in the northeastern Tibetan Plateau.
Superposition of induced polarization signals measured on pyrite–sand mixtures
Authors: Martin Tina , Weller Andreas 
Published: March 2023

SUMMARY
Induced polarization (IP) is a common method in ore exploration. IP spectra measured over a wide frequency range can be used to characterize material properties of ores, slags and other residual material from mines and processing facilities. Previous studies have shown that IP parameters are sensitive to type, content or grain size of electronically conductive or semi-conductive minerals. Up to now, a variety of experiments has been performed on sand mixtures with fractions of ore minerals. Most experiments consider only a single fraction with a fixed grain size. We continue a series of experiments that have been done with sand–pyrite mixtures. The presented study compares IP spectra recorded for samples either with a single grain radius fraction (E-samples) or with two different grain radii fractions (Z-samples). The spectra are fitted to Pelton models. A Debye decomposition that provides a relaxation time distribution (RTD) is applied to the complex conductivity spectra. The RTD indicates separated maxima only if the ratio of mean grain radii is larger than a factor five. The resolution of the phase spectra and the spectra of imaginary part of conductivity is lower. Even though the volumetric pyrite content is equal in each fraction, the phase spectra and RTD of the Z-samples indicate much higher signals for the pyrite fraction with smaller grain radius. The same observation is made for the chargeability that shows larger values for decreasing grain radii. This finding contradicts existing theories that consider the chargeability as a suitable proxy of the volumetric content of ore minerals. We explain the observed effect by an interaction between neighbouring pyrite particles. The conductivity of the mixtures of the E-samples increases with decreasing grain radius of the pyrite fraction. This effect is attributed to dissolution effects on the surface of the pyrite particles during the sample preparation. We find that the additive superposition of the phase spectra of two E-samples is in good agreement with the measured phase spectra of the Z-samples (measured superposition) containing the two corresponding pyrite fractions. The agreement is slightly worse for the spectra of imaginary part of conductivity, where the measured superposition overestimates the mathematical superposition. The experimental results of our study motivate a further improvement of existing mechanistic models.

Published: March 2023

SUMMARYThe 15 January 2022 eruption of the Hunga–Tunga volcano generated a Lamb pressure wave propagating all over the globe and triggering a tsunami throughout the planet. A first atmospheric wave arrived 16 hr after the eruption on the French Mediterranean coasts and propagated southward. A second one originating from Africa was observed 4 hr later with an attenuated amplitude. The first wave can be roughly defined either by a N wave or a sinusoid signal with a period close to 50 min and an amplitude of 130 Pa. In the Mediterranean Sea, the tsunami was recorded by almost all standard coastal tide gauges or pressure gauges. The French tide gauge stations recorded water waves with amplitudes ranging from a few centimetres to 10 cm and with periods ranging from 10 min to 1 hr. Numerical simulation of the tsunami is performed by the operational code Taitoko for different atmospheric sources. Non-linear shallow water equations are solved by a finite-difference method, using the nested multigrid approach. The tsunami is generated by calculating analytically the atmospheric pressure gradient in the momentum equations. Comparisons of time-series between numerical solutions and records are satisfactory for most tide-gauges along the French Mediterranean coast. Sensitivity analysis on the atmospheric source and on the resolution is performed. For most tide-gauge stations, numerical results show that the wave forms depend first on local resonance phenomena.

Abstract
Access to newer, fast, and cheap sequencing techniques, particularly on the single-cell level, have made transcriptomic data of tissues or single cells accessible to many researchers. As a consequence, there is an increased need for in situ visualization of gene expression or encoded proteins to validate, localize, or help interpret such sequencing data, as well as put them in context with cellular proliferation. A particular challenge for labeling and imaging transcripts are complex tissues that are often opaque and/or pigmented, preventing easy visual inspection. Here, we introduce a versatile protocol that combines in situ hybridization chain reaction, immunohistochemistry, and proliferative cell labeling using 5-ethynyl-2′-deoxyuridine, and demonstrate its compatibility with tissue clearing. As a proof-of-concept, we show that our protocol allows for the parallel analysis of cell proliferation, gene expression, and protein localization in bristleworm heads and trunks.

AbstractBackgroundBacterial infections are common in patients with cancer, and many bacteria have developed resistance to currently used antibiotics.ObjectivesWe evaluated the in vitro activity of eravacycline (a recently developed fluorocycline) and comparators against bacterial pathogens isolated from patients with cancer.MethodsAntimicrobial susceptibility testing was performed using CLSI-approved methodology and interpretive criteria for 255 Gram-positive and 310 Gram-negative bacteria. MIC and susceptibility percentage were calculated according to CLSI and FDA breakpoints when available.ResultsEravacycline had potent activity against most Gram-positive bacteria, including MRSA. Of 80 Gram-positive isolates with available breakpoints, 74 (92.5%) were susceptible to eravacycline. Eravacycline had potent activity against most Enterobacterales, including ESBL-producing organisms. Of 230 Gram-negative isolates with available breakpoints, 201 (87.4%) were susceptible to eravacycline. Eravacycline had the best activity among comparators against carbapenem-resistant Enterobacterales, with 83% susceptibility. Eravacycline was also active against many non-fermenting Gram-negative bacteria, with the lowest MIC90 value among comparators.ConclusionsEravacycline was active against many clinically significant bacteria isolated from patients with cancer, including MRSA, carbapenem-resistant Enterobacterales, and non-fermenting Gram-negative bacilli. Eravacycline might play an important role in the treatment of bacterial infections in patients with cancer, and additional clinical evaluation is warranted.
Cyclical Time Is Greener: The Impact of Temporal Perspective on Pro-Environmental Behavior

Published: March 2023

Abstract
The natural environment is deteriorating. However, humans have not slowed down their pace of resource depletion and environmental destruction. This research takes a particular path to understanding environmental consumption—through a focus on temporal perspective. Evidence from six studies demonstrates the positive effect of a cyclical temporal perspective, versus a linear temporal perspective, on consumers’ pro-environmental behavior. The research shows that individuals with a cyclical perspective are more likely to include the environment in the self, which leads to higher pro-environmental behavioral intentions and more pro-environmental behavior. This temporal perspective effect is attenuated for consumers already high on green values. The authors also examine a marketer-controlled moderator and show that consumers are more likely to purchase a pro-environmental product when they see a temporal-perspective-congruent promotional appeal. The research contributes to both the time perception and the environmental consumption literature and offers several practical implications for organizations to promote sustainable consumer behavior.

AbstractIn environmental surveillance, cluster detection of environmental black spots is of major interest due to the adverse health effects of pollutants, as well as their known synergistic effect. Thus, this paper introduces three new spatial scan statistics for multivariate functional data, applicable for detecting clusters of abnormal air pollutants concentrations measured spatially at a very fine scale in northern France in October 2021 taking into account their correlations. Mathematically, our methodology is derived from a functional multivariate analysis of variance, an adaptation of the Hotelling T2-test statistic, and a multivariate extension of the Wilcoxon test statistic. The approaches were evaluated in a simulation study and then applied to the air pollution dataset.

Abstract

Background
International travel increases the risk of acquisition of antibiotic-resistant bacteria and antibiotic resistance genes (ARGs). Previous studies have characterized the changes in the gut microbiome and resistome of Western travellers; however, information on non-Western populations and the effects of travel-related risk factors on the gut microbiome and resistome remains limited.

Methods
We conducted a prospective observational study on a cohort of 90 healthy Chinese adult residents of Hong Kong. We characterized the microbiome and resistome in stools collected from the subjects before and after travelling to diverse international locations using shotgun metagenomic sequencing and examined their associations with travel-related variables.

Results
Our results showed that travel neither significantly changed the taxonomic composition of the faecal microbiota nor altered the alpha (Shannon) or beta diversity of the faecal microbiome or resistome. However, travel significantly increased the number of ARGs. Ten ARGs, including aadA, TEM, mgrB, mphA, qnrS9 and tetR, were significantly enriched in relative abundance after travel, eight of which were detected in metagenomic bins belonging to Escherichia/Shigella flexneri in the post-trip samples. In sum, 30 ARGs significantly increased in prevalence after travel, with the largest changes observed in tetD and a few qnrS variants (qnrS9, qnrS and qnrS8). We found that travel to low- or middle-income countries, or Africa or Southeast Asia, increased the number of ARG subtypes, whereas travel to low- or middle-income countries and the use of alcohol-based hand sanitizer (ABHS) or doxycycline as antimalarial prophylaxis during travel resulted in increased changes in the beta diversity of the faecal resistome.

Conclusions
Our study highlights travel to low- or middle-income countries, Africa or Southeast Asia, a long travel duration, or the use of ABHS or doxycycline as antimalarial prophylaxis as important risk factors for the acquisition/enrichment of ARGs during international travel.

Abstract

Background
Extended spectrum beta-lactamase producing Enterobacterales (ESBL-PE) present a risk to public health by limiting the efficacy of multiple classes of beta-lactam antibiotics against infection. International travellers may acquire these organisms and identifying individuals at high risk of acquisition could help inform clinical treatment or prevention strategies.

Methods
We used data collected from a cohort of 528 international travellers enrolled in a multicentre US-based study to derive a clinical prediction rule (CPR) to identify travellers who developed ESBL-PE colonization, defined as those with new ESBL positivity in stool upon return to the United States. To select candidate features, we used data collected from pre-travel and post-travel questionnaires, alongside destination-specific data from external sources. We utilized LASSO regression for feature selection, followed by random forest or logistic regression modelling, to derive a CPR for ESBL acquisition.

Results
A CPR using machine learning and logistic regression on 10 features has an internally cross-validated area under the receiver operating characteristic curve (cvAUC) of 0.70 (95% confidence interval 0.69–0.71). We also demonstrate that a four-feature model performs similarly to the 10-feature model, with a cvAUC of 0.68 (95% confidence interval 0.67–0.69). This model uses traveller’s diarrhoea, and antibiotics as treatment, destination country waste management rankings and destination regional probabilities as predictors.

Conclusions
We demonstrate that by integrating traveller characteristics with destination-specific data, we could derive a CPR to identify those at highest risk of acquiring ESBL-PE during international travel.
Possible evidence for a large-scale enhancement in the Lyman-α forest power spectrum at redshiftz≥ 4

Published: March 2023

ABSTRACTInhomogeneous reionization enhances the 1D Ly α forest power spectrum on large scales at redshifts z ≥ 4. This is due to coherent fluctuations in the ionized hydrogen fraction that arise from large-scale variations in the post-reionization gas temperature, which fade as the gas cools. It is therefore possible to use these relic fluctuations to constrain inhomogeneous reionization with the power spectrum at wavenumbers $\log _{10}(k/{\rm km^{-1}\, s})\lesssim -1.5$. We use the Sherwood-Relics suite of hybrid radiation hydrodynamical simulations to perform a first analysis of new Ly α forest power spectrum measurements at 4.0 ≤ z ≤ 4.6. These data extend to wavenumbers $\log _{10}(k/{\rm km^{-1}\, s})\simeq -3$, with a relative uncertainty of 10–20 per cent in each wavenumber bin. Our analysis returns a 2.7σ preference for an enhancement in the Ly α forest power spectrum at large scales, in excess of that expected for a spatially uniform ultraviolet background. This large-scale enhancement could be a signature of inhomogeneous reionization, although the statistical precision of these data is not yet sufficient for obtaining a robust detection of the relic post-reionization fluctuations. We show that future power spectrum measurements with relative uncertainties of ≲ 2.5 per cent should provide unambiguous evidence for an enhancement in the power spectrum on large scales.
Initial flash and spectral formation of Type Ia supernovae with an envelope: applications to overluminous SNe Ia

Published: March 2023

ABSTRACT
Overluminous Type Ia supernovae (SNe Ia) show peculiar observational features, for which an explosion of a super-massive white dwarf (WD) beyond the classical Chandrasekhar-limiting mass has been suggested, largely based on their high luminosities and slow light-curve evolution. However, their observational features are diverse, with a few extremely peculiar features whose origins have not been clarified; strong and persisting C II lines, late-time accelerated luminosity decline and red spectra, and a sub-day time-scale initial flash clearly identified so far at least for three overluminous SNe Ia. In the present work, we suggest a scenario that provides a unified solution to these peculiarities, through hydrodynamic and radiation transfer simulations together with analytical considerations; a C+O-rich envelope (∼0.01−0.1M⊙) attached to an exploding WD. Strong C II lines are created within the shocked envelope. Dust formation is possible in the late phase, providing a sufficient optical depth thereafter. The range of the envelope mass considered here predicts an initial flash with time-scale of ∼0.5−3 days. The scenario thus can explain some of the key diverse observational properties by a different amount of the envelope, but additional factors are also required; we argue that the envelope is distributed in a disc-like structure, and also the ejecta properties, e.g. the mass of the WD, play a key role. Within the context of the hypothesized super-Chandrasekhar-mass WD scenario, we speculatively suggest a progenitor WD evolution including a spin-up accretion phase followed by a spin-down mass-ejection phase.
Accretion within the innermost stable circular orbit: analytical thermodynamic solutions in the adiabatic limit
Authors: Mummery Andrew , Balbus Steven 
Published: March 2023

ABSTRACT
We present analytical solutions for the thermodynamic (temperature, pressure, density, etc.) properties of thin accretion flows in the region within the innermost stable circular orbit (ISCO) of a Kerr black hole, the first analytical solutions of their kind. These solutions are constructed in the adiabatic limit and neglect radiative losses, an idealization valid for a restricted region of parameter space. We highlight a number of remarkable properties of these solutions, including that these solutions cool for radii rI/2 &lt; r &lt; rI, before increasing in temperature for 0 &lt; r &lt; rI/2, independent of black hole spin and assumptions regarding the equation of state of the accretion flow. The radiative temperature of these solutions can, for some values of the free parameters of the theory, peak within the ISCO and not in the main body of the disc. These solutions represent a fundamentally new class of analytical accretion solutions, which are both non-circular and non-radial in character.
