Published: November 2024

ABSTRACT
This paper presents a novel perspective on correlation functions in the clustering analysis of the large-scale structure of the Universe. We begin with the recognition that pair counting in bins of radial separation is equivalent to evaluating counts in cells, which can be modelled using a filtered density field with a binning window function. This insight leads to an in situ expression for the two-point correlation function (2PCF). Essentially, the core idea underlying our method is to introduce a window function to define the binning scheme, enabling pair counting without binning. This approach develops an idea of generalized 2PCF, which extends beyond conventional discrete pair counting by accommodating non-sharp-edged window functions. In the context of multiresolution analysis, we can implement a fast algorithm to estimate the generalized 2PCF. To extend this framework to N-point correlation functions using current optimal edge-corrected estimators, we developed a binning scheme that is independent of the specific parametrization of polyhedral configurations. In particular, we demonstrate a fast algorithm for the three-point correlation function (3PCF), where triplet counting is accomplished by assigning either a spherical tophat or a Gaussian filter to each vertex of triangles. Additionally, we derive analytical expressions for the 3PCF using a multipole expansion in Legendre polynomials, accounting for filtered field (binning) corrections. Our method provides an exact solution for quantifying binning effects in practical measurements and offers a high-speed algorithm, enabling high-order clustering analysis in extremely large data sets from ongoing and upcoming surveys such as Euclid, Large Synoptic Survey Telescope (LSST), and Dark Energy Spectroscopic Instrument (DESI).

Published: November 2024

ABSTRACT
This work investigated the dynamics of planets in binary systems and provided insights into the stability and evolution of these systems. We explored the influence of a nearby secondary star on planetary growth and evolution, focusing on S-type configurations. We tracked the orbits of the planets and analysed their stability over long time-scales, considering various parameters such as mass, eccentricity, and inclination. Our results show that the presence of a secondary star can significantly impact the growth and evolution of planets, leading to changes in their orbits and potential ejection from the system, however, it was possible to identify stable planets even in systems experiencing multiple disturbances. One of the most significant results of the work was the analysis of the increased material in the disc near the primary star, which contributes to planet growth, driven by the density spirals influenced by the binary star. These findings have important implications for the search for habitable exoplanets and emphasize the need for further studies of planetary systems in binary star environments.

ABSTRACT
We conducted the MeerKAT Vela Supercluster survey, named Vela$-$$\textrm {H}\, \scriptstyle \mathrm{I}$, to bridge the gap between the Vela SARAO (South African Radio Astronomy Observatory) MeerKAT Galactic Plane Survey (Vela$-$SMGPS, $-2^{\circ } \le b \le 1^{\circ }$), and optical and near-infrared spectroscopic observations of the Vela Supercluster (hereafter Vela$-$OPT/NIR) at $|b| \gtrsim 7^{\circ }$. Covering coordinates from $263^{\circ } \le \ell \le 284^{\circ }$ and $1^{\circ } \le b \le 6.2^{\circ }$ above, and $-6.7^{\circ } \le b \le -2^{\circ }$ below the Galactic Plane (GP), we sampled 667 fields spread across an area of ${\sim } \rm 242 ~deg^2$. With a beam size of ${\sim } 38 \ \mathrm{ arcsec} \times 31 \ \mathrm{ arcsec}$, Vela$-$$\textrm {H}\, \scriptstyle \mathrm{I}$ achieved a sensitivity of $\langle \rm rms \rangle = 0.74$$\rm mJy\, beam^{-1}$ at 44.3 $\rm km\, s^{-1}$ velocity resolution over ${\sim }$67 h of observations. We catalogued 719 galaxies, with only 211 (29 per cent) previously documented in the literature, primarily through the H i Parkes Zone of Avoidance survey (HIZOA), Two Micron All-sky Survey Extended Source Catalog (2MASX), and Wide-field Infrared Survey Explorer (WISE) data bases. Among these known galaxies, only 66 had optical spectroscopic redshift information. We found marginal differences of less than one channel resolution for all galaxies in common between HIZOA and Vela$-$SMGPS, and a mean difference of $70 \pm 15$$\rm km\, s^{-1}$ between optical and $\textrm {H}\, \scriptstyle \mathrm{I}$ velocities. Combining data from Vela$-$SMGPS, Vela$-$$\textrm {H}\, \scriptstyle \mathrm{I}$, and Vela$-$OPT/NIR confirmed the connection of the Hydra/Antlia filament across the GP and revealed a previously unknown diagonal wall at a heliocentric velocity range of $6500\!\!-\!\!8000$$\rm km\, s^{-1}$. Vela$-$$\textrm {H}\, \scriptstyle \mathrm{I}$ reinforces the connection between the first wall at $18\,500\!\!-\!\!20\,000$$\rm km\, s^{-1}$ and the inner Zone of Avoidance. The second wall seems to traverse the GP at $270^{\circ } \le \ell \le 279^{\circ }$, where it appears that both walls intersect, jointly covering the velocity range $18\,500\!\!-\!\!21\,500$$\rm km\, s^{-1}$.
The formation of multiples in small-N subclusters
Authors: Ambrose Hannah E , Whitworth A P 
Published: November 2024

ABSTRACT
We explore the relative percentages of binary systems and higher-order multiples that are formed by pure stellar dynamics, within a small subcluster of N stars. The subcluster is intended to represent the fragmentation products of a single isolated core, after most of the residual gas of the natal core has dispersed. Initially, the stars have random positions, and masses drawn from a lognormal distribution. For low-mass cores spawning multiple systems with Sun-like primaries, the best fit to the observed percentages of singles, binaries, triples, and higher-order systems is obtained if a typical core spawns on average between $N=$ 4.3 and 5.2 stars, specifically a distribution of N with mean $\mu _{_{N}}\sim 4.8$ and standard deviation $\sigma _{_N}\sim 2.4$. This fit is obtained when $\sim 50~{{\ \rm per\ cent}}$ of the subcluster’s internal kinetic energy is invested in ordered rotation and $\sim 50~{{\ \rm per\ cent}}$ in isotropic Maxwellian velocities. There is little dependence on other factors, for example mass segregation or the rotation law. While such high values of N are at variance with the lower values often quoted (i.e. $N\!=\!1\,\,{\rm or}\,\,2$), very similar values ($N\!=\!4.3\pm 0.4$ and $N\!=\!4.5\pm 1.9$) have been derived previously by completely independent routes, and seem inescapable when the observed distribution of multiplicities is taken into account.
Alkaline phosphatase is useful for predicting giant cell arteritis complications in patients with polymyalgia rheumatica
Authors: Yamashita Ryo , Izumi Yusuke , Hiramoto Jun 
Published: November 2024

ABSTRACT

Objectives
This study determined whether alkaline phosphatase (ALP) can be used to distinguish giant cell arteritis (GCA) complications in patients with polymyalgia rheumatica (PMR).

Methods
This retrospective study included patients diagnosed with PMR between January 2014 and October 2023 at our hospital. The predictive accuracy of biomarkers for diagnosing GCA was evaluated. Logistic regression was performed to identify factors predicting GCA complications.

Results
In total, 128 participants were included in this study and divided into two groups: isolated PMR (n = 111) and PMR with GCA (n = 17). The median ALP level of PMR with GCA group was significantly higher than that of the isolated PMR group (242.0 [interquartile range, 221.0–595.0] vs. 187.0 [interquartile range 97.5–254.5] U/L, P &lt; .001). Setting a cut-off value of 214 U/L for ALP yielded a sensitivity and specificity of 0.88 and 0.55, respectively, for diagnosing GCA. Multivariate analysis revealed that ALP was a significant independent variable in the complications of GCA (odds ratio, 25.2; P = .032).

Conclusions
ALP can help distinguish GCA complications in patients with PMR.

Abstract
Ribosome profiling (Ribo-Seq) has revolutionised our understanding of translation, but the increasing complexity and volume of Ribo-Seq data present challenges for its reuse. Here, we formally introduce RiboSeq.Org, an integrated suite of resources designed to facilitate Ribo-Seq data analysis and visualisation within a web browser. RiboSeq.Org comprises several interconnected tools: GWIPS-viz for genome-wide visualisation, Trips-Viz for transcriptome-centric analysis, RiboGalaxy for data processing and the newly developed RiboSeq data portal (RDP) for centralised dataset identification and access. The RDP currently hosts preprocessed datasets corresponding to 14840 sequence libraries (samples) from 969 studies across 96 species, in various file formats along with standardised metadata. RiboSeq.Org addresses key challenges in Ribo-Seq data reuse through standardised sample preprocessing, semi-automated metadata curation and programmatic information access via a REST API and command-line utilities. RiboSeq.Org enhances the accessibility and utility of public Ribo-Seq data, enabling researchers to gain new insights into translational regulation and protein synthesis across diverse organisms and conditions. By providing these integrated, user-friendly resources, RiboSeq.Org aims to lower the barrier to reproducible research in the field of translatomics and promote more efficient utilisation of the wealth of available Ribo-Seq data.

Abstract
This article mainly discusses tritium concentrations in monthly precipitation at Hiroshima City during 2021. The tritium concentrations, which were measured with a low background liquid scintillation counter, fluctuated from 0.16 to 0.78 Bq L−1. Additionally, hydrogen and oxygen stable isotopes and ionic species were measured in order to characterize precipitation, and their trends including tritium concentrations were compared with data collected in other regions of Japan in previous studies. Although the results showed the characteristics of precipitation were similar to those observed in the other regions, the tritium concentrations were found to be contrary to behavior expected from the latitude effect and some of the observed ionic components were suggested to be continental in origin. Since these results are not common at other sites in Japan, the tritium concentration in the westernmost region of Honshu, including Hiroshima City, may be influenced by Asian continental influences.
Construction of a realistic voxel phantom of the Japanese red fox (Vulpes vulpes japonica) based on MRI imaging and estimation of its background external radiation dose rate from environmental radionuclides
Authors: Ohtsuka Yoshihito , Hisamatsu Shun’ichi 
Published: November 2024

Abstract
In this study, we selected the Japanese red fox (Vulpes vulpes japonica) as a representative mid-size mammal from the forests near the spent nuclear fuel reprocessing plant at Rokkasho. A fox voxel phantom was constructed based on magnetic resonance imaging of a female red fox caught in Rokkasho. This phantom consisted of 264 × 321 × 383 voxels (each voxel size: 0.78 × 0.78 × 2 mm) with internal organs. The external radiation dose rate to the voxel phantom by beta and gamma rays from environmental radionuclides was estimated using a Monte Carlo code (EGS4 and UCPIXEL). We estimated the dose rates to the phantom on the ground and in an average fox burrow in the Rokkasho forest, which were 11 and 27 nGy h−1, respectively. Assuming that the animal on the ground was irradiated by cosmic rays of 27 nGy h−1, the total external dose rate was evaluated to be 38 nGy h−1. Based on the assumption that the fox lives on the ground for 12 h and in the burrow for 12 h, the dose rate was estimated to be 33 nGy h−1.
Simulation of the shielding effect of lead apron undergoing chest CT scan
Authors: Xin Lin , Zhuo Weihai 
Published: November 2024

Abstract
Lead aprons are used to reduce radiation dose to patients. As the distance between the lead apron and the edge of the scan range increases, organ dose is expected to decrease, but with increasing scattered radiation dose in the body. By simulation, this work aims at estimate whether the organ dose increases due to the scattered radiation in the body with lead apron. A standard-sized male and a female phantom is used to simulate organ doses of chest scans in various lead apron shielding situations. Simulations in this work considered different distance between the edge of the 0.35-mm lead apron and the edge of the scan range. For the female phantom, the dose to the gonads was significantly reduced (56% on average), but not as much as men (78% on average). However, the amount of dose reduction is small for male and female phantoms (0.0082 mGy/100 mAs and 0.0160 mGy/100 mAs).

Published: November 2024

Abstract
Using D2 gas as a substrate, this study investigated the hydrogen deposition velocities of farmland soils around a reprocessing plant located in Rokkasho Village, Aomori, Japan. To determine the hydrogen deposition velocities, closed chambers with fans were set on the soils of farmlands that grow Japanese radishes, and changes in D2 concentration in the chambers were measured by gas chromatography. Results showed hydrogen deposition velocities of six soils were within the range of 1.0 × 10−4 ~ 2.0 × 10−4 m s−1. The heavy water (HDO) formations were detected in the soil after the experiment, showing the oxidation of D2 and conversion to water. Relationships between the obtained hydrogen deposition velocities and environmental conditions such as soil temperature, moisture and porosity were examined. A correlation was found between the hydrogen deposition velocities and soil gas phase rate (r = 0.98, p &lt; 0.05).
Absorption and translocation to fruit for cesium applied on apple tree leaf surface
Authors: Kawabata Hitoshi , Yanai Masumi , Takaku Yuichi , Hisamatsu Shun’ichi 
Published: November 2024

Abstract
We investigated the behavior of stable Cs+ ions contained in droplets applied directly on the leaf surfaces of plumleaf crab apple trees (2–3 years old Malus domestica ‘Alps Otome’) at three different fruit growing stages: before bearing fruit, early fruit development and late fruit development stages. Most of the Cs was rapidly transferred from the leaf surfaces into the applied leaves after application, and then gradually transferred to the fruit through the branches. The mean proportion of Cs transferred to fruit by harvest time ranged from 11 to 30% not directly depending on the fruit growing stages. Cs absorption from leaf surfaces was faster at early and late fruit development stages than before bearing fruit stage, and Cs transfer from leaf surfaces to the fruit was faster as the fruit growing stage progressed. To describe the transfer of Cs, we constructed a compartment model using the datasets of obtained for each fruit growing stage. However, it did not well reproduce the measured values, showing that further studies are necessary.
Effect of PI3-kinase inhibitors on DNA double strand break repair pathways: observations using a site specific DSB induction system
Authors: Myodo Tomoki , Sakamoto Yuki , Sato Keita , Kobayashi Honami , Iijima Kenta , Komatsu Kenshi , Matsuura Shinya , Tauchi Hiroshi 
Published: November 2024

Abstract
We established two types of site-specific DNA double strand breaks (DSB) induction systems to elucidate factors which affect the efficiency or quality of DSB repair. For mutation assays, a site specific DSB was generated by the transient expression of a zinc finger nuclease which targets the human HPRT1 gene. A cell line in which time and site specific DSBs can be generated in a HR reporter construct was used for homology-directed repair (HR) analysis. By using these two systems, we investigated the effects of PI3-kinase inhibitors on the efficiency and quality of DSB repair. Ataxia telangiectasia mutated (ATM) kinase inhibition resulted a decrease in mutant frequency and a slight increase in deletion-type mutations accompanied by microhomology. Furthermore, the HR frequency increased significantly when ATM kinase activity was inhibited. Thus, ATM kinase activity might be involved in the suppression of DSB end resection, and this may promote DSB repair through canonical non-homologous end joining.

Authors: Satoh Yuhi , Ohtsuka Yoshihito 
Published: November 2024

Abstract
To precisely evaluate the concentration of iodine-129 (129I) in soil samples, changes in this concentration after thermal drying under several temperature conditions were investigated. The soil sample used in this study was collected from a site located near a nuclear fuel reprocessing plant, which atmospherically released 129I in a test operation in 2006–2008, resulting in the soil sample containing higher 129I concentrations than their natural levels. Thermal drying was conducted from 60°C to 110°C and compared with lyophilization result, showing that the 129I concentration in the soil sample was statistically comparable among all the drying treatments.
Preliminary results of spatial distribution of radon and thoron with associated parameters in soil around active faults in Japan
Authors: Janik Miroslaw , Gomez Christopher , Kodaira Satoshi , Hasan Md Mahamudul 
Published: November 2024

Abstract
The radon (Rn) and thoron (Tn) concentrations and other environmental parameters were measured in the vicinity of active faults in two regions with different geology structure of Japan. The range of measured values was from 1.2 to 74 kBq m$^{-3}$, 1.1 to 38.9 kBq m$^{-3}$, 0% to 4.35%, and 2$\times $10$^{-13}$ to 4$\times $10$^{-11}$ m$^{2}$, for Rn, Tn, CO$_{2}$, and soil permeability, respectively. Significant differences in the measured parameters were observed, suggesting that Rn concentrations near faults are strongly influenced by geological structure and fault type. Based on statistical analysis, good correlations were found between Rn, Tn, and CO$_{2}$ (carried gas ) concentrations. It is planned to continue the study with measurements at a number of additional sites.
Study of seasonal variation of accident-derived atmospheric radiocesium in Koriyama City, Fukushima Prefecture, Japan during 2011–2014
Authors: Hasegawa Hidenao , Akata Naofumi , Okuyama Katsuhiko , Ochiai Shinya , Kakiuchi Hideki , Ueda Shinji 
Published: November 2024

Abstract
This study measured the atmospheric concentration and deposition flux of radiocesium in Koriyama City, Fukushima Prefecture, Japan, from November 2011 to October 2014. The results show synchronous seasonal change in atmospheric concentration and deposition flux of radiocesium, which is high during winter to early spring and low during summer to autumn. These seasonal variations are similar to those observed in Fukushima City but differ from those in Namie Town, Fukushima Prefecture, comprising a larger contaminated forest area. The evaluation of the relationship between atmospheric 137Cs concentration or 137Cs specific activity in atmospheric particulate matter (PM) and deposition density of 137Cs in PM source area suggest that stronger winds blowing from areas with relatively large 137Cs deposition (west of Koriyama City) toward the study site affect the site’s atmospheric 137Cs concentrations.
A pilot study to directly estimate radiation-induced mutation in large Japanese field mouse duo sample, mother and offspring, excluding unknown father, using ddRAD sequencing
Authors: Ishiniwa Hiroko , Endoh Daiji , Tamaoki Masanori , Onuma Manabu 
Published: November 2024

Abstract
DNA mutations are one of the effects of radiation exposure. A large amount of radioactive materials was released into the environment from the Fukushima Daiichi Nuclear Power Plant after a major earthquake and tsunami. Wild animals and plants living in highly radiation-contaminated areas are constantly exposed to high doses of radiation, and concerns occur about its effects on their health and the next generations. As a pilot study, double-digest restriction site-associated DNA (ddRAD) sequencing was conducted to assess the incidence of mutations in wild large Japanese field mice collected from the evacuation area. The optimal combination of restriction enzymes, encompassing the functionally important coding regions, was selected using in silico analysis. These enzymes were used for ddRAD sequence analysis of females and their fetuses to evaluate mutation rates. The results indicated that no significant differences were observed in mutation rates between mothers and fetuses in the study areas.
