Authors: Timofeev Matthew I. , Guarnieri Francesco V. , Huddy Julia E. , Scheideler William J. 
Published: October 2023

Metal halide perovskites are a promising photovoltaic technology for energy harvesting due to their potential for low cost via high-speed manufacturing and their flexible light form factors offering high power per weight. This study presents an investigation of the energy harvesting performance of perovskite solar cells under monochromatic illumination via finite element simulations and experimental validation with high-efficiency double cation perovskite solar cells. Device performance across a broad range of illumination intensity is analyzed, providing insights into the mechanisms limiting energy harvesting in medium- and long-range wireless power transfer. The simulations also provide a guideline for compositional engineering of wide bandgap perovskites to improve the spectral match to efficient monochromatic sources. Based on these results, we show how perovskite solar cells can become a platform for efficient (&gt;33%) medium-range wireless power transfer at the 5–50 m scale for power levels of 1 mW to 1 W.
On indicating and dealing with uncertainty in healthcare dialogues
Authors: Gärtner Julia , Bührig Kristin , Harendza Sigrid 
Published: October 2023

Abstract
In the context of diagnostic uncertainty moments of irritation can arise, which linguistically disguise uncertainty of the physicians or result in uncertainty on the patient’s side. We investigated the occurrence of uncertainty in history-taking encounters by reconstructing the dealing with uncertainty within the interaction process. The analysis is based on data from a simulation where medical students in the physician’s role interact with simulated patients. In the case study, our hermeneutical in-depth-analysis of one interaction process between a medical student and a patient reveals a certain communication pattern by the medical student resulting from an emerging dilemma which consists of a diagnostically unreasonable procedure but an offer of ‘at least something’ to the desperate patient.
Porcine circoviruses in Malaysia

Published: October 2023

Abstract
Over one decade since the first report, Malaysian porcine circovirus 2 (PCV2) molecular detection rates remain high at 83.78 and 83.54% for farm and sampled domestic pig population levels respectively. Clinically healthy finishers also showed a high detection rate of 94.74%. Most notably, a major genotype shift from genotype PCV2b to PCV2d was observed. PCV2 antigen was also detected in the Malaysian wild boar population, sharing significant nucleotide identity similarities with PCV2 strains of domestic pigs. Porcine circovirus 3 (PCV3), which was discovered not too long ago in 2017, has been confirmed to be present among the Malaysian commercial pig population at a molecular prevalence of 41.67% at the farm level and 17.02% at the sampled domestic pig population level respectively. Most recently, PCV4 had been detected in Malaysia, albeit at a much lower molecular prevalence of 4.08%. Both PCV4-positive samples originated from clinically healthy finishers. Phylogenetic analyses suggested the possibility of PCV3 and PCV4 being introduced by international trade activities. For practical and economic reasons, in the local Malaysian pig industry, field diagnostics of PCV2 cases generally rely on clinical and post-mortem findings, together with herd antibody titer and qPCR viremia titer. Currently, commercial PCV3 diagnostics service and vaccines are not available locally. With updated local PCV2 epidemiology, control and management efforts could be adapted into more effective strategies. A common management strategy for PCV2 challenge in farms could be applied for the time being to control potential PCV3 problems in the farms. As for PCV4, a larger number of field samples from cases of different clinical manifestations needs to be included to obtain a more accurate epidemiological picture.
DFT insights into the effects of substitutionally doped Sb defects in CuIn(S,Se)2 solar cell absorber

Published: October 2023

Abstract
Metal chalcogenide-based semiconductors are gaining attention for optoelectronic applications like thin-film photovoltaics (PV). Sb dopant incorporation in CuIn(S,Se)2 (CISSe) solar cell has been proven to significantly enhance PV performance, as demonstrated in our previous experimental work. However, the underlying mechanisms behind this improvement remained unclear. In this study, we report on the influence of substitutionally doped Sb defect on the structural, formation energy, band structure, and optical absorption properties in CISSe, employing the hybrid HSE06 functional within the density functional theory framework. We find that the Sb prefers to substitute at In site, resulting in the most stable Sb-doped CISSe structure. Under cation-poor growth conditions, Sb prefers to substitute on In sites, while under anion-poor growth conditions, it shows a preference for substituting on Se sites. Interestingly, only SbIn defects do not form impurity states in the band gap. Additionally, SbIn, SbS, and SbSe show a reduction in the band gap. Our results reveal that Sb-doped CISSe exhibits enhanced optical absorption in the IR to visible regions, leading to increased photocurrent generation and improved photovoltaic device efficiency, consistent with our experimental findings. These findings provide valuable theoretical insights into the influence of Sb-doping in CISSe, aiding the design of effective metal chalcogenide PV.
Preparation and properties of MAO self-healing anticorrosion film on 5B70 Al alloy
Authors: Wu Mingjin , Jiang Feng 
Published: October 2023

Abstract
Micro-arc oxidation (MAO) was a new surface treatment technology for Al alloys. However, the MAO ceramic film could not provide long-term protective performance owing to its inherent porous structure. In this work, a new type of CeO2-sealed GO/Al2O3 composite film on 5B70 Al alloy with excellent corrosion resistance was prepared by integrating MAO and the hole sealing technique. The experimental results indicated that the loose and porous MAO ceramic film could serve as a ‘shield’ and a ‘reservoir’, respectively, to obtain improved impedance and sufficient corrosion inhibitor loading. Compared to the original MAO ceramic film or GO/Al2O3 composite film, The GO/Al2O3 composite film after sealing treatment for 60 min had lower porosity and better corrosion resistance. In addition, CeO2-sealed GO/Al2O3 composite film exhibited a positive self-healing effect in 3.5 wt% NaCl solution.
Quantum tunneling of spin-1/2 and spin-3/2 particles in the black holes of asymptotically safe gravity
Authors: Rahim Rehana , Rahim Kulsoom 
Published: October 2023

Abstract
Hawking initiated study of radiations from black holes. The black hole thermodynamics holds a significant importance in understanding of quantum nature of gravity. In this article, Hawking radiations have been studied by employing the semi-classical perspective of quantum tunneling. Dirac and Rarita-Schwinger equations have been employed to determine the tunneling probabilities of spin-1/2 and spin-3/2 particles, respectively, in the background of black holes developed in the asymptotically safe gravity. Hawking temperature determined in both cases is in agreement.

Abstract
We study the effect of the Large Magellanic Cloud (LMC) on the dark matter (DM) distribution in the Solar neighborhood, utilizing the Auriga magneto-hydrodynamical simulations of Milky Way (MW) analogues that have an LMC-like system. We extract the local DM velocity distribution at different times during the orbit of the LMC around the MW in the simulations. As found in previous idealized simulations of the MW-LMC system, we find that the DM particles in the Solar neighborhood originating from the LMC analogue dominate the high speed tail of the local DM speed distribution. Furthermore, the native DM particles of the MW in the Solar region are boosted to higher speeds as a result of a response to the LMC's motion.
We simulate the signals expected in near future xenon, germanium, and silicon direct detection experiments, considering DM interactions with target nuclei or electrons. We find that the presence of the LMC causes a considerable shift in the expected direct detection exclusion limits towards smaller cross sections and DM masses, with the effect being more prominent for low mass DM. Hence, our study shows, for the first time, that the LMC's influence on the local DM distribution is significant even in fully cosmological MW analogues.
The impact of cross-covariances between the CMB and reconstructed lensing power
Authors: Trendafilova Cynthia 
Published: October 2023

Abstract
Weak gravitational lensing of the Cosmic Microwave Background (CMB) changes CMB statistics in a nontrivial way, allowing for reconstruction of the lensing potential and the use of these reconstructed maps in determining cosmological parameters that affect the formation of intervening large-scale structures. Although in principle there are correlations between the primary CMB and the reconstructed lensing potential due to the lensing procedure itself, in practice CMB analyses treat these as negligible when combining these band powers in likelihoods. In this paper we quantify explicitly the impact on parameter constraints due to these cross-covariances between the lensed CMB and reconstructed lensing power, and we compare to the effect of including all lensing-induced non-Gaussian covariances, which have previously shown to impact parameter constraints on the order of 10%. We perform our analysis for a range of experimental setups, scanning over instrumental noise levels of 0.5 to 10.0 μK-arcmin in temperature assuming fully polarized detectors, and using a fixed beam size of 1.4 arcmin. When the correlations between the lensed CMB and lensing power are neglected, we find that forecasted constraints shift by at most 3% of the error bar for a 6-parameter ΛCDM model, and for the noise levels considered in this paper. For some of the ΛCDM extensions considered here, however, these correlations have a nontrivial impact, in some cases more than 10% of the error bar, even for current experimental noise levels.

Abstract
The fastest and heaviest pulsar, PSR J0952-0607, with a mass of M = 2.35±0.17 M
⊙,
has recently been discovered in the disk of the Milky Way Galaxy. In response to this discovery, a
new RMF model, 'NITR' has been developed. The NITR model's naturalness has been confirmed by
assessing its validity for various finite nuclei and nuclear matter properties, including
incompressibility, symmetry energy, and slope parameter values of 225.11, 31.69, and 43.86 MeV,
respectively. These values satisfy the empirical/experimental limits currently available. The
maximum mass and canonical radius of a neutron star (NS) calculated using the NITR model
parameters are 2.355 M
⊙ and 13.13 km, respectively, which fall within the range of PSR
J0952-0607 and the latest NICER limit. This study aims to test the consistency of the NITR model
by applying it to various systems. As a result, its validity is extensively calibrated, and all
the nuclear matter and NS properties of the NITR model are compared with two established models
such as IOPB-I and FSUGarnet. In addition, the NITR model equation of state (EOS) is employed to
obtain the properties of a dark matter admixed NS (DMANS) using two approaches (I) single-fluid
and (II) two-fluid approaches. In both cases, the EOS becomes softer due to DM interactions, which
reduces various macroscopic properties such as maximum mass, radius, tidal deformability, etc. The
various observational data such as NICER and HESS are used to constrain the amount of DM in both
cases. Moreover, we discuss the impact of dark matter (DM) on the nonradial f-mode frequency of
the NS in a single fluid case only and try to constrain the amount of DM using different
theoretical limits available in the literature.
Stochastic gravitational wave background from early dark energy
Authors: Kitajima Naoya , Takahashi Tomo 
Published: October 2023

AbstractWe study the production of stochastic gravitational wave background in early dark energy (EDE) models. It is generated by resonant amplification of scalar field fluctuations, which can easily take place for typical EDE potential based on the string axion or α-attractor model. The resultant spectrum of gravitational wave background is computed by performing 3D lattice simulations. We show that, specifically in some class of a generalized α-attractor EDE model, a significant amount of gravitational waves can be produced via tachyonic instability with a peak around femto-Hz frequency range. Models predicting such gravitational waves can be constrained by cosmic microwave background observations.
Random sequential adsorption of aligned rectangles with two discrete orientations: finite-size scaling effects
Authors: Petrone Luca , Lebovka Nikolai , Cieśla Michał 
Published: October 2023

Abstract
We study saturated packings produced according to the random sequential adsorption (RSA) protocol built of identical rectangles deposited on a flat, continuous plane. An aspect ratio of rectangles is defined as the length-to-width ratio,

f
=
l

/

w

. The rectangles have a fixed unit area (i.e.

l

), and therefore, their shape is defined by the value of f (

l

). The rectangles are allowed to align either vertically or horizontally with equal probability. The particles are deposited on a flat square substrate of side length

) and periodic boundary conditions are applied along both directions. The finite-size scaling are characterized by a scaled anisotropy defined as

α

. We showed that the properties of such packings strongly depend on the value of aspect ratio f and the most significant scaling effects are observed for relatively long rectangles when

l

(i.e.

α

). It is especially visible for the mean packing fraction as a function of the scaled anisotropy α. The kinetics of packing growth for low to moderate rectangle anisotropy is to be governed by

ln

law, where t is proportional to the number of RSA iterations, which is the same as in the case of RSA of parallel squares. We also analyzed global orientational ordering in such packings and properties of domains consisting of a set of neighboring rectangles of the same orientation, and the probability that such domain forms a percolation.
On the connection between temperature and volatility in ideal agent systems
Authors: Börner Christoph J , Hoffmann Ingo , Stiebel John H 
Published: October 2023

Abstract
Models for spin systems known from statistical physics are applied by analogy in econometrics in the form of agent-based models. Researchers suggest that the state variable temperature T corresponds to volatility σ in capital market theory problems. To the best of our knowledge, this has not yet been theoretically derived, for example, for an ideal agent system. In the present paper, we derive the exact algebraic relation between T and σ for an ideal agent system and discuss implications and limitations.

Abstract
Cosmic-ray muon imaging (muography) has been applied in
various fields in recent years, in which plastic scintillators are
one of the frequently selected detectors internationally. Therefore,
a triangular scintillator strip based muography detection system has
been proposed in the development of the μ Scattering and
Transmission imaging faCility (μSTC). Before the mass production
of detector units, this work studied the impacts of multiple factors
on the light collection efficiency (LCE) and the position resolution
(σ) of plastic scintillators. These factors include
configurations of wavelength shifting (WLS) fibers, fiber grooves on
scintillators, coupling optical glues and silicon photomultiplier
(SiPM) readout mode. According to the simulated results, an
empirical formula was proposed to quantitatively describe the
relation between the LCE and σ, which has seldom been studied
before. In this formula, σ reduces as a power-law function of
the LCE. The SiPM readout mode (single-end or double-end output) and
fiber groove treatments show no significant influence on the
σ-LCE relation. LCE variations due to different factors lead
to a difference in σ of less than 0.2 mm in the whole range
of LCE. Accordingly, these factors are nearly equivalent in the
improvement of detector position resolution. In comparison, the muon
hit position reconstruction method nearly halves the σ after
using angular and gap corrections. Thus, a better reconstruction
method shows greater importance than the efforts made to increase
LCEs. The simulation study in this work will provide good references
for the construction of plastic scintillators of the μSTC
platform in the near future.

Abstract
High precision experiments with muons and pions often
require tracking charged particles with O(100 μm)
single-hit resolution, possibly with particle identification
capabilities, down to very low momenta (p ≲
100 MeV/c). In such conditions, the particle trajectories are
strongly affected by the interaction with the detector material, and
the reconstruction of the kinematic observables consequently
deteriorates. A good compromise between resolution and material
budget can be obtained with a Time Projection Chamber (TPC), if very
light gases and a high-granularity readout are used. In this paper,
we present a characterization of the GridPix detector in
helium-isobutane gas mixtures, within a TPC with 9 cm maximum
drift. Measurements of the main electron drift properties for these
gas mixtures are also presented.
Landscape ecological risk assessment of chongming dongtan wetland in shanghai from 1990 to 2020
Authors: Cao Yong , Dong Bin , Xu Haifeng , Xu Zhili , Wei Zhezhu , Lu Zhipeng , Liu Xiao 
Published: October 2023

Abstract
Landscape ecological risk assessment can assess the stability, vulnerability, and anti-interference ability of the ecosystem based on the characteristics, structure, and function of the landscape in order to determine the degree and distribution of landscape ecological risk. In recent years, due to human activities and global climate change, the area and ecological quality of the Chongming Dongtan wetland have been decreasing. As an important wintering habitat and transit point on the ‘East Asia-Australia migration line’, the population and habitat security of wintering migratory birds are also threatened. Therefore, the landscape index method was used to assess the ecological risk of the Chongming Dongtan wetland. Based on transfer analysis and spatial autocorrelation analysis, the spatial and temporal changes of landscape ecological risk were revealed. The findings are as follows: (1) Natural landscapes such as mudflats, grasslands, and waters have been declining, while artificial landscapes such as cultivated land, construction land, and woodland have been gradually expanding, indicating a shift from natural to artificial landscapes. (2) Overall, the landscape ecological risk is showing an increasing trend. Wetlands have moved from being dominated by the lowest and medium ecological risks to being evenly distributed by all ecological risk classes. Notably, there has been a rapid increase in landscape ecological risk in 2000. The highest-risk areas have expanded by 9346.95 hm2, gradually encroaching from the buffer zone into the reclamation area and the nature reserve. Conversely, the lowest ecological risk areas have decreased by 7091.82 hm2, primarily concentrated in nature reserves. (3) The aggregation of landscape ecological risks continues to decrease, indicating a reduced likelihood of dramatic changes in ecological risks.
What would a US green hydrogen energy economy look like?
Authors: Tonon Thomas 
Published: October 2023

Abstract
Detailed description is given for a hypothetical US hydrogen economy with solar and wind energy supplying virtually all current energy needs and with electrolytic hydrogen the energy carrier and storage medium. Fossil fuels provide nonfuel products (plastics, chemicals, cement and asphalt). Only current technologies are considered and hydrogen storage accommodates generation intermittency and variability, using pit storage of high-pressure vessels in open air, yielding daily storage round-trip energy installation costs of 722 and 538 $/kWh for electric and thermal, respectively; and for power, 2351 and 2240 $/kW for electric and thermal, respectively. For long-duration storage, the costs are 94.1 and 23.8 $/kWh and 937 and 845 $/kW, respectively. Increased energy generation 20% over baseline accommodates low-season generation, obviates much required storage and ensures that reserves are topped off; 96% of US 2022 total energy consumption is provided for. In the default scenario (demand energy portions: half photovoltaic, quarter onshore wind and quarter offshore wind), the surface area for the farms (including offshore surface) requires ~4.6% of the US 48-state land area. About 350 pit storage sites provide both daily and long-duration storage, with the latter accounting for complete loss of generation for 4 days over a quarter of the nation. Hydrogen pipelines and a renewed electric grid transmit and distribute energy. The installation cost of the public infrastructure is ~$27.8 trillion for the default scenario. Alternative scenarios show significant infrastructure and cost savings when batteries are used for transportation and/or utility storage, provided current insufficiencies can be overcome. Broadly, cost levels in money, surface and infrastructure are within existing levels already achieved in historical events and modern living.
