‘I partied my way to [my] Hungary’: The agency-driven engagements of Hungarian-Australians to shape feelings of place and belonging outside their diaspora tourism programme
Authors: Kantek Julia , Onnudottir Helena , Veljanova Irena 
Published: October 2022

ABSTRACT
The Balassi Institute is Hungary’s cultural diplomacy organisation. The Institute’s 10-month ‘Balassi program’ invites Hungarians from the diaspora to participate in a culturally immersive and educational experience in Hungary. This paper draws on interviews with 17 Hungarian-Australians who attended the programme between 2001 and 2018. Bourdieu’s Habitus, capital and ‘field of possibles’ are used to analyse their experiences of belonging during their time in Hungary, particularly everyday engagements where they partied, danced, and formed friendships in nightclubs, folk bars, and community groups. The paper highlights that while the Balassi programme’s curriculum aims to habituate national consciousness, the defining elements of belonging were agency-driven. By manoeuvring their capital and prioritising everyday social engagements, participants constructed ‘relationships with the nation’, while maintaining a minimum commitment to the programme. Thus, when exploring the aims of State-led diaspora tourism programmes, participant choices outside these programmes must be considered a prominent force in shaping belonging.
Enemies and friends. The instrumental social construction of populist identity through twitter in Italy at the time of COVID-19
Authors: Loner Enzo 
Published: October 2022

ABSTRACT
Based on 2020 Twitter data, this article studies the social construction of populist identity in Italy. Starting from Tajfel's social identity theory (1978), the research aims at dissecting the elements at the basis of the populist identity construction process. The analysis focuses on both quantitative analysis and qualitative inspection of the tweets of four populist leaders, namely Salvini (LN), Meloni (FDI), Berlusconi (FI), and Di Maio (M5S). Results highlight the outgroup's position and its functional role in strengthening relative deprivation to facilitate ingroup identification. In addition, the populist social identity is built on group membership and the biased comparison between the ingroup and one or more outgroups. Results demonstrate how leaders’ strategies change based on being in government or not and according to their position on the left-right axis. In this context, the pandemic offered a further political opportunity, especially to those who have found themselves in government.
Dynamics of a nonminimally coupled scalar field in asymptotically AdS
4 spacetime
Authors: Pandya Alex , Ripley Justin L 
Published: October 2022

Abstract
We numerically investigate the stability of four-dimensional asymptotically anti-de Sitter (AdS
4) spacetime for a class of nonminimally coupled scalar field theories. In particular, we study how the coupling affects the formation of black holes, and the transfer of energy to different spatial/temporal scales. We conclude by detailing the well-known analogy between the nonminimally coupled scalar-field stress-energy tensor and that of a viscous relativistic fluid, and discuss the limitations of that analogy when it is applied to anisotropic scalar field configurations in asymptotically AdS spacetimes.
Size-tunable bismuth quantum dots for self-powered photodetectors under ambient conditions

Published: October 2022

Abstract
Although black phosphorus analogue, bismuthene, has been extensively investigated in recent years, yet the investigation into the photoelectronic devices is still in its infancy. In this contribution, uniform zero-dimensional (0D) bismuth (Bi) quantum dots (QDs) with different sizes were successfully synthesized by a simple solvothermal method. The as-synthesized 0D Bi QDs serve as working electrode materials by a direct deposition for photoelectrochemical (PEC)-type photodetection. The PEC results demonstrate that the as-fabricated 0D Bi QD-based electrode not only possess suitable self-powered broadband photoresponse, but also displays excellent photodetection performance. Under simulated light, the photocurrent density and photoresponsivity of the as-fabricated 0D Bi QD-based electrode can reach 2690 nA cm−2, and 22.0 μA W−1, respectively. In addition, the as-prepared Bi QDs with the average diameter of 17 nm exhibit the best PEC photoresponse behavior in the studied size range of Bi QDs, mainly ascribed to the synergistic effect of suitable band gap and accessible active sites. It is anticipated that the uniform Bi QDs can be served as building blocks for a variety of photoelectronic devices, further expanding the application prospects of bismuthene, and can provide in-depth acknowledge on the performance optimization of monoelement Bi-based optical devices.
Fisher forecasts for primordial non-Gaussianity from persistent homology

Published: October 2022

Abstract
We study the information content of summary statistics built from the multi-scale topology
of large-scale structures on primordial non-Gaussianity of the local and equilateral type. We use
halo catalogs generated from numerical N-body simulations of the Universe on large scales as a
proxy for observed galaxies. Besides calculating the Fisher matrix for halos in real space, we
also check more realistic scenarios in redshift space. Without needing to take a distant observer
approximation, we place the observer on a corner of the box. We also add redshift errors
mimicking spectroscopic and photometric samples. We perform several tests to assess the
reliability of our Fisher matrix, including the Gaussianity of our summary statistics and
convergence. We find that the marginalized 1-σ uncertainties in redshift space are
Δf
NL
loc ∼ 16 and Δf
NL
equi ∼ 41 on a survey volume of 1 (Gpc/h)3. These
constraints are weakly affected by redshift errors. We close by speculating as to how this
approach can be made robust against small-scale uncertainties by exploiting (non)locality.
Concealing Dirac neutrinos from cosmic microwave background
Authors: Biswas Anirban , Ghosh Dilip Kumar , Nanda Dibyendu 
Published: October 2022

Abstract
The existence of prolonged radiation domination prior to
the Big Bang Nucleosynthesis (BBN), starting just after the inflationary
epoch, is not yet established unanimously. If instead, the universe undergoes
a non-standard cosmological phase, it will alter the Hubble expansion rate
significantly and may also generate substantial entropy through non-adiabatic
evolution. This leads to a thumping impact on the properties of relic species
decoupled from the thermal bath before the revival of the standard radiation
domination in the vicinity of the BBN. In this work, considering the Dirac nature
of neutrinos, we have studied decoupling of ultra-relativistic right-handed
neutrinos (νR
s) in presence of two possible non-standard cosmological phases.
While in both cases we have modified Hubble parameters causing faster expansions
in the early universe, one of the situations predicts a non-adiabatic evolution
and thereby a slower redshift of the photon temperature due to the expansion.
Considering the most general form of the collision term with
Fermi-Dirac distribution and Pauli blocking factors, we have solved
the Boltzmann equation numerically to obtain ΔNeff for the
three right-handed neutrinos. We have found that for a large portion
of parameter space, the combined effect of early decoupling of νR

as well as the slower redshift of photon bath can easily hide the
signature of right-handed neutrinos, in spite of precise measurement
of ΔNeff, at the next generation CMB experiments
like CMB-S4, SPT-3G etc. This however will not be applicable for the scenarios
with only fast expansion.
Equation of states in the curved spacetime of slowly rotating degenerate stars
Authors: Hossain Golam Mortuza , Mandal Susobhan 
Published: October 2022

Abstract
We compute the equation of state for an ensemble of degenerate fermions by
using the curved spacetime of a slowly rotating axially symmetric star. We show
that the equation of state computed in such curved spacetime depends on the
gravitational time dilation as well as on the dragging of inertial frames,
unlike an equation of state computed in a globally flat spacetime. The effect
of gravitational time dilation leads to a significant enhancement of the
maximum mass limit of a degenerate neutron star. However, such an enhancement
due to the frame-dragging effect is extremely small. Nevertheless, in general
relativity the frame-dragging effect is crucial for computing angular momentum
of the star which is also shown to be enhanced significantly due to the usage of
curved spacetime in computing the equation of state.
Terahertz radiation generation in doped semiconductor interacting with femtosecond pulse in constant magnetic field
Authors: Grishkov V E , Uryupin S A 
Published: October 2022

Abstract
The generation of terahertz (THz) radiation in a doped semiconductor with a sufficiently large bandgap interacting with a femtosecond pulse of IR range has been investigated. Generation occurs due to the simultaneous effect on the conduction electrons of a constant magnetic field and time-dependent ponderomotive force. The spectral composition, total energy and shape of the THz radiation pulse are found.
Detection of laser-plasma experiment radiation using nanoparticle coatings as fluorescent sensors
Authors: Barberio M. , Salvadori M. , Vallières S. , Skantzakis E. , Sarkissian A. , Antici P. 
Published: October 2022

Abstract
In this paper, we test the possibility to use luminescence
of metal (aluminum and silver) nanoparticles (NPs), synthesized
using different laser-driven ablation methods, as sensors for
radiation detection. Energetic photon and electron radiation
produced by intense plasma induces a red-shift in the luminescence
emitted by the NPs. Observing the phenomenon over long time periods
(hours), we see an oscillating behavior of the luminescence signal,
which can be explained in terms of de-trapping of electrons caused
by energetic radiations and re-trapping in the empty levels of low
energetic electrons emitted from the plasma. Observing the
luminescence shift allows detecting electromagnetic and radiation
pollution, e.g. when dispersed in an experimental chamber.
Practical X-ray beam spectrometry with cadmium telluride detector in 10–300 kVp range at Czech Metrology Institute. Part II. Unfolding
Authors: Šolc J. , Dryák P. , Rusňák J. , Sochor V. , Vykydal Z. 
Published: October 2022

Abstract
The paper summarizes computational methods and software tools used at Czech Metrology Institute for unfolding of X-ray photon fluence spectra from detector spectra measured with a cadmium telluride (CdTe) spectrometer directly in the X-ray beam. Fluence spectra were determined using multi-channel unfolding software GRAVEL. Response functions were calculated by Monte Carlo (MC) method using the general-purpose code MCNP® in version 6.2 with EPRDATA14 photon cross-section tables. The detailed MC model of the CdTe spectrometer was developed and it was validated by comparison with full-energy peak detection efficiencies measured with selected radionuclide sources. The adopted methods and tools enable to fulfil requirements of the ISO 4037 standard dealing with the necessity of direct measurement of X-ray beam photon fluence spectra whose parameters do not comply with the ones listed in the standard. The instrumentation part for the X-ray beam spectrometry at CMI is described in a separate paper [1].

Published: October 2022

Abstract
Tropical rivers are dynamic CO2 sources. Regional patterns in the partial pressure of CO2 (pCO2) and relationships with other a/biotic factors in densely populated and rapidly developing river delta regions of Southeast Asia are still poorly constrained. Over one year, at 21 sites across the river system in the Red River Delta (RRD), Vietnam, we calculated pCO2 levels from temperature, pH, and total alkalinity and inter-linkages between pCO2 and phytoplankton, water chemistry and seasonality were then assessed. The smaller, more urbanized, and polluted Day River had an annual median pCO2 of 5000 ± 3300 µatm and the larger Red River of 2675 ± 2271 µatm. pCO2 was 1.6 and 3.2 times higher during the dry season in the Day and Red rivers respectively than the rainy season. Elevated pCO2 levels in the Day River during the dry season were also 2.4-fold higher than the median value (2811 ±  3577 µatm) of calculated and direct pCO2 measurements in >20 sub/tropical rivers. By further categorizing the river data into Hanoi City vs. other less urban-populated provinces, we found significantly higher nutrients, organic matter content, and riverine cyanobacteria during the dry season in the Day River across Hanoi City. Forward selection also identified riverine cyanobacteria and river discharge as the main predictors explaining pCO2 variation in the RRD. After accounting for the shared effects (14%), river discharge alone significantly explained 12% of the pCO2 variation, cyanobacteria uniquely a further 21%, while 53% of the pCO2 variance was unexplained by either. We show that the urbanization of rivers deltas could result in increased sources of riverine pCO2, water pollution, and harmful cyanobacterial blooms. Such risks could be mitigated through water management to increase water flows in problem areas during the dry season.
Exact solutions of temperature-dependent Smoluchowski equations
Authors: Osinsky A I , Brilliantov N V 
Published: October 2022

Abstract
We report a number of exact solutions for temperature-dependent Smoluchowski equations (TDSEs). These equations quantify the ballistic agglomeration, where the evolution of densities of agglomerates of different size is entangled with the evolution of the mean kinetic energy (partial temperatures) of such clusters. The obtained exact solutions may be used as a benchmark to assess the accuracy and computational efficiency of the numerical approaches, developed to solve the TDSEs. Moreover, they may also illustrate the possible evolution regimes in these systems. The exact solutions have been obtained for a series of model rate coefficients, and we demonstrate that there may be an infinite number of such model coefficient which allow exact analysis. We compare our exact solutions with the numerical solutions for various evolution regimes; an excellent agreement between numerical and exact results proves the accuracy of the exploited numerical method.
Fabry–Perot interference enhanced transverse magneto-optical Kerr effect in Ce:YIG nanopore array on an anodic aluminum oxide template
Authors: Zhang Weiwei , Lu Yao , An Kang 
Published: October 2022

Abstract
The all-dielectric magneto-optical (MO) structure has garnered considerable interest due to its enhanced MO effect and low ohmic loss compared to the magnetoplasmonic structure. In this study, the effect of Fabry–Perot (F–P) interference on the enhancement of the transverse magneto-optical Kerr effect (T-MOKE) as well as sensing performance is theoretically investigated in a dielectric MO structure composed of cerium-substituted yttrium iron garnet (Ce:YIG) nanopore array coating a nanoporous anodic aluminum oxide (AAO) film standing on an aluminum sheet referred to as the AAO/Al template. The system is particularly interesting because the MO response is significantly enhanced in the position of the F–P interference, in which the T-MOKE signal is close to a 5-fold increase compared with the reference Ce:YIG film. Additionally, the sensing performance shows that the all-dielectric nanopore-based system proposed here provides an alternative to fabricating gas and solution detectors with low ohmic loss.

Published: October 2022

Abstract
MXene with expanding interlayer and tunable terminations emerge as promising candidates for metal ion storage. Herein, we develop a facile urea decomposition strategy to obtain ultrathin nitrogen-modified Ti3C2T
x
(N-UT-Ti3C2T
x
) with optimized terminations as anode for sodium/potassium ion storage. Experimental results have shown that NH3 molecules produced by urea pyrolysis could introduce two types of nitrogen modifications in Ti3C2, function substitution for –OH (FS) and surface absorption on –O (SA). During subsequent hydrothermal and heating processes, the nitrogen atoms in situ substitute the lattice carbon in Ti3C2 (LS). Further, the effects of these nitrogen modifications in Ti3C2 on diffusion kinetics of Na+ and K+ are investigated by first-principles calculations. The superior Na+ storage performances of the N-UT-Ti3C2T
x
anode are the main attribute of the nitrogen modification of LS in Ti3C2, while the excellent K+ storage performances come from the synergistic effects of the nitrogen modifications of FS and LS in Ti3C2. This work emphasizes the effectiveness of surface engineering of nitrogen modifications and optimized terminations for improving the electrochemical performances of Ti3C2T
x
and inspires the design of heteroatom modified MXenes for energy storage.
Changes in extreme rainfall over mainland China induced by landfalling tropical cyclones

Published: October 2022

AbstractLandfalling tropical cyclones (LTCs) is one of the most serious meteorological disasters in China due to the provided severe wind and heavy rainfall. Tropical cyclone–induced rainfall in China has been proved to decrease in recent decades. However, how landfalling tropical cyclone–induced extreme rainfall (LTCER) has changed across China, as well as the relationship between LTCER and LTCs remains poorly understood. Accordingly, the spatiotemporal distribution characteristics and long-term changes of LTCER over mainland China during the past 60 years were investigated, by using an Objective Synoptic Analysis Technique to identify LTCER. Mid and high latitudes are exposed to a greater risk of extreme rainfall from northward-moving landfalling tropical cyclones (LTCs). Meanwhile, LTCER tends to increase from 1960 to 2019 across mainland China (characterized by a decrease from 1960 to 1989 and an increase from 1990 to 2019). The LTCER trend exhibits a large spatial difference, with an increase near and to the north of 30°N, but no significant change to the south of 30°N. Moreover, the central latitude of the LTCER zone to the north of 30°N has shifted significantly southwards, while that to the south of 30°N has shifted north. Further analysis revealed that the average latitude of the LTC intensity centers to the north/south of 30°N exhibits the same shift to that of LTCER, indicating that the shift of LTCER has mainly been imposed by the migration of LTCs.
Methods for comparing digital applications in buildings and districts
Authors: Rehmann Felix , Cudok Falk , Streblow Rita 
Published: October 2022

Abstract
The so-called Energiewende is a complex task with a variety of stakeholders, regulations, technical infrastructure, and proposed solutions. Buildings are an important sector for increasing resource and energy efficiency, as in Germany around 35% of end energy usage can be attributed to them. Digital applications can help reduce these emissions through more efficient planning, operating, renovation, or demolition. Depending on the task and the parties involved, the complexity of descriptions and data models can vary from simple energy efficiency labels used in the labeling process of buildings to complex individual data models used for simulation. However, these specific information systems are often non-transferable, are hard to compare in their restrictions and requirements, and hence increase the overall costs of digital solutions. A good understanding is needed to preserve economic and ecological benefits while maintaining privacy and security aspects. To compare digital applications, a variety of solutions are identified. This paper first provides an overview of the identified solutions, namely frameworks, taxonomies, and ontologies. While the identified frameworks focus more on technological aspects and are complex to use, they provide an in-depth understanding. Taxonomies can be used for a scientific (e.g., classification of methods) comparison and provide simple relationships. Ontologies provide relationships and definitions while being task-dependent. We conclude that comparing the underlying data models of digital applications is a complex task and dependent on the application and its infrastructure. However, a variety of tasks refers to the same tools and data. After discussing these approaches, we then give an overview of digital applications developed by German researchers. Last, we give an insight on how to combine these aspects in our ongoing research. To summarize, in this paper we give an overview of the complexity involved in transferring digital solutions in the building sector, provide a method used for comparing applications and describe a solution to compare infrastructure and digital tools built for it.
