Authors: Kimura Yoshinari , Sasaki Michihiro , Tohmyoh Hironori 
Published: August 2024

Abstract
Sensors for detecting chloride ions have been required for routine monitoring of industry and human health. This study proposes a concept of an ion sensor based on CuO
x
nanofilms with different oxygen contents. The CuO
x
-based sensors exhibited an increase in DC current for those with low oxygen content and a decrease for those with high oxygen content following exposure to a chloride ion solution. AC impedance analysis suggested differential reactions of chloride ions in the bulk and surface regions of CuO
x
, dependent on the oxygen content. For the CuO
x
-based sensors with a ratio of 0.78 oxygen to copper atoms at chloride ion concentrations of 10−1000 ppm, the sensitivity in the bulk region calculated from AC impedance was 61−2926, which was higher than the sensitivity of 1.3−2.6 calculated from DC impedance. Finally, CuO
x
-based sensors demonstrated identifiability for chloride ions compared to sodium and calcium ions.
Reduction mechanism of loss tangent of scandium-doped aluminum nitride thin film by post-deposition annealing
Authors: Teshigahara Akihiko , Enomoto Tetsuya , Yamada Hideo , Yoshida Shinya 
Published: August 2024

Abstract
Scandium-doped aluminum nitride thin films are key materials for MEMS applications including bulk acoustic wave devices for communication. Although one drawback is the increase in the loss tangent with increasing Sc concentration, the loss tangent is reported to decrease after post-deposition annealing. However, the underlying mechanisms remain unclear. In this study, we propose the hypothesis that a low-resistivity thin layer near the surface of a substrate is one of the main reasons for the high loss tangent, and that annealing enhances the resistivity, eventually decreasing the loss tangent. The reasonability of the hypothesis was successfully confirmed by analyzing the frequency response of the loss tangent using an equivalent circuit with current–voltage characteristics, cathodoluminescence, etc. This achievement represents a significant step toward advanced methods for reducing the loss tangent and its application to other thin-film materials.

Published: August 2024

Transparansi dan akuntabilitas adalah dua dari tujuh prinsip manajemen keuangan. Oleh karena itu maka laporan keuangan keuangan harus menganut prinsip tersebut baik laporan keuangan organisasi bisnis maupun organisasi nirlaba. Laporan keuangan yang telah manganut prinsip transparan dan akuntabilitas berdampak terhadap keberlanjutan organisasi. Para stake holder dapat mudah memahami dan memberikan kepercayaan yang tinggi terhadap pembacanya, sehingga laporan keuangan dapat dijadikan sebuah dasar untuk mengambil langkah atau menetapkan berbagai program. Secara khusus laporan keuangan organisasi nirlaba seperti gereja, masjid dan organisasi sosial lainnya yang nota bene sumber pendapatannya adalah berasal dari sumbangan anggota organisasi. Semakin tinggi tingkat kepercayaan maka berpotensi semakin besar sumbangan yang akan diberikan oleh anggota. Namun dalam rangka terwujudnya laporan keuangan yang transparan dan akuntabel dibutuhkan sistim informasi akuntansi yang memadai. Sistim informasi akuntansi yang baik tercermin dari berbagai dokumen yang dilahirkan yang dapat merekam seluruh transaksi yang terjadi di dalam organisasi. Penelitian ini dilaksanakan di Gerja Kristen Protestan Simalungun (GKPS) Hosianna. Hasil observasi menunjukkan terdapat banyak kegiatan ibadah yang terjadi di lingkup gereja dan rumit nya aliran kas. Setiap kegiatan ibadah terdapat pengumpulan dana. Penelitian ini dimulai dari mengidentifikasi berbagai kegiatan ibadah yang ada, merancang formulir sebagai media untuk merekam data keuangan yang terjadi, dan selanjutnya menyusun laporan keuangan berdasarkan Pernyataan Standar Akuntansi Keuagan (PSAK) 45. Hasil yang didapat dari penelitian ini yaitu terciptanya 19 formulir yang diberi nama formulir Hos-01 sampai Hos-19 dan berdasarkan data yang direkam di dalam formulir tersebut disusunlah laporan keuangan yang mengacu pada proses akuntansi. Laporan keuangan yang dilahirkan adalah laporan posisi keuangan, laporan aktivitas, laporan arus kas dan catatan atas laporan keuangan

In this paper, we show that in characteristic zero, the condition \textit{	finite local $k-$rational} is not necessary for the algebra of differential operators on a commutative and unitary $k-$algebra to be equal to that of endomorphisms. But the \textit{finite dimension} is necessary for the algebra of differential operators to be an algebra of finite dimension.
Unraveling the Origins of an Extreme Solar Eruptive Event with Hard X-Ray Imaging Spectroscopy
Authors: Vievering Juliana T. , Vourlidas Angelos , Krucker Säm 
Published: August 2024

Abstract
Hard X-ray (HXR) observations are crucial for understanding the initiation and evolution of solar eruptive events, as they provide a key signature of flare-accelerated electrons and heated plasma. The potential of high-cadence HXR imaging for deciphering the erupting structure, however, has not received adequate attention in an era of extreme ultraviolet (EUV) imaging abundance. An extreme solar eruptive event on 2022 September 5 observed on the solar far side by both Parker Solar Probe and Solar Orbiter provides the opportunity to showcase the power of HXR imaging in the absence of high-cadence EUV imaging. We investigate the evolution of flare energy release through HXR timing, imaging, and spectral analyses using data from the Spectrometer/Telescope for Imaging X-rays (STIX) on board Solar Orbiter. STIX provides the highest cadence imaging of the energy release sites for this far-side event and offers crucial insight into the nature of energy release, timing of flare particle acceleration, and evolution of the acceleration efficiency. We find that this is a two-phase eruptive event, rather than two distinct eruptions, as has been previously suggested. The eruption begins with an initial peak in flare emission on one side of the active region (AR), marking the rise/destabilization of a loop system followed by notable episodes of energy release across the AR and an eruptive phase associated with a very fast coronal mass ejection, type III radio bursts, and solar energetic particles. We demonstrate that high-cadence HXR imaging spectroscopy is indispensable for understanding the formation of powerful, space-weather relevant eruptions.
Solar Rotation and Activity for Cycle 24 from SDO/AIA Observations
Authors: Shokri Zahra , Alipour Nasibe , Safari Hossein 
Published: August 2024

Abstract
Differential rotation plays a crucial role in the dynamics of the Sun. We study the solar rotation and its correlation with solar activity by applying a modified machine learning algorithm to identify and track coronal bright points (CBPs) from the Solar Dynamics Observatory/Atmospheric Imaging Assembly observations at 193 Å during cycle 24. For more than 321,440 CBPs, the sidereal and meridional velocities are computed. We find the occurring height of CBPs to be about 5627 km above the photosphere. We obtain a rotational map for the corona by tracking CBPs at the formation height of Fe xii (193 Å) emissions. The equatorial rotation (14.°40 to 14.°54 day−1) and latitudinal gradient of rotation (−3.°0 to −2.°64 day−1) show very slightly positive and negative trends with solar activity (sunspots and flares), respectively. For cycle 24, our investigations show that the northern hemisphere has more differential rotation than the southern hemisphere, confirmed by the asymmetry of the midlatitude rotation parameter. The asymmetry (ranked) of the latitudinal gradient of the rotation parameter is concordant with the sunspot numbers for 7 yr within the 9 yr of the cycle; however, for only 3 yr, it is concordant with the flare index. The minimum horizontal Reynolds stress changes from about −2500 m2 s−2 (corresponding to high activity) in 2012 and 2014 to −100 m2 s−2 (corresponding to low activity) in 2019 over 5° to 35° latitudes within cycle 24. We conclude that the negative horizontal Reynolds stress (momentum transfer toward the Sun’s equator) is a helpful indication of solar activity.
Revealing the Production Mechanism of High-energy Neutrinos from NGC 1068
Authors: Das Abhishek , Zhang B. Theodore , Murase Kohta 
Published: August 2024

Abstract
The detection of high-energy neutrino signals from the nearby Seyfert galaxy NGC 1068 provides us with an opportunity to study nonthermal processes near the center of supermassive black holes. Using the IceCube and latest Fermi-LAT data, we present general multimessenger constraints on the energetics of cosmic rays and the size of neutrino emission regions. In the photohadronic scenario, the required cosmic-ray luminosity should be larger than ∼1%−10% of the Eddington luminosity and the emission radius should be ≲15R
S in low-β plasma and ≲3R
S in high-β plasma. The leptonic scenario overshoots the NuSTAR or Fermi-LAT data for any emission radii we consider, and the required gamma-ray luminosity is much larger than the Eddington luminosity. The beta-decay scenario also violates not only the energetics requirement but also gamma-ray constraints, especially when the Bethe–Heitler and photomeson production processes are consistently considered. Our results rule out the leptonic and beta-decay scenarios in a nearly model-independent manner and support hadronic mechanisms in magnetically powered coronae if NGC 1068 is a source of high-energy neutrinos.

Abstract
We present the phase-connected timing solutions of all five pulsars in globular cluster M3 (NGC 5272), namely PSRs M3A to F (PSRs J1342+2822A to F), with the exception of PSR M3C, from FAST archival data. In these timing solutions, those of PSRs M3E and F are obtained for the first time. We find that PSRs M3E and F have low-mass companions and are in circular orbits with periods of 7.1 and 3.0 days, respectively. For PSR M3C, we have not detected its signal in all 41 observations. We found no X-ray counterparts for these pulsars in archival Chandra images in the band of 0.2–20 keV. From the autocorrelation function analysis of M3A and M3B’s dynamic spectra, the scintillation timescale ranges from 7.0 ± 0.3 to 60.0 ± 0.6 minutes, and the scintillation bandwidth ranges from 4.6 ± 0.2 to 57.1 ± 1.1 MHz. The measured scintillation bandwidths from the dynamic spectra indicate strong scintillation, and the scattering medium is anisotropic. From the secondary spectra, we captured a scintillation arc only for PSR M3B with a curvature of 649 ± 23 m−1 mHz−2.

< 1.5 Mpc (∼70% of the Abell radius). For VC04, we obtained 90 new spectroscopic redshifts of galaxies, observed with the 11 m Southern African Large Telescope. We found the Schechter parameters of the VC04 LF to be M* = −24.ͫ41 ± 0.44, α = −1.10 ± 0.20, and ϕ* = 8.84 ± 0.20. Both the redshift data and the LF confirm VC04 to be a rich but not yet fully relaxed cluster. We independently determined the LF of VC04 on membership defined by the red-sequence method and demonstrated that this method can be used in the absence of high spectroscopic coverage over a cluster. This allowed us to determine the LFs of VC02 and VC08. We also derived the LFs of the Coma, Norma, and Virgo clusters to similar depth and extent as the VSCL clusters. We found that the Schechter parameters of VC04 are within 1σ uncertainties of these local clusters, as well as VC02 and VC08. We do not find significant differences between the LFs in the different cluster environments probed in this work down to

Lyα Emission Line Profiles of Extreme [O iii]- emitting Galaxies at z ≳ 2: Implications for Lyα Visibility in the Reionization Era
Authors: Tang Mengtao , Stark Daniel P. , Ellis Richard S. , Topping Michael W. , Mason Charlotte , Li Zhihui , Plat Adèle 
Published: August 2024

Abstract
JWST observations have recently begun delivering the first samples of Lyα velocity profile measurements at z > 6, opening a new window into the reionization process. Interpretation of z ≳ 6 line profiles is currently stunted by limitations in our knowledge of the intrinsic Lyα profile (before encountering the intergalactic medium (IGM)) of the galaxies that are common at z ≳ 6. To overcome this shortcoming, we have obtained resolved (R ∼ 3900) Lyα spectroscopy of 42 galaxies at z = 2.1–3.4 with similar properties as are seen at z > 6. We quantify a variety of Lyα profile statistics as a function of [O iii]+Hβ equivalent width (EW). Our spectra reveal a new population of z ≃ 2–3 galaxies with large [O iii]+Hβ EWs (>1200 Å) and a large fraction of Lyα flux emerging near the systemic redshift (peak velocity ≃0 km s−1). These spectra indicate that low-density neutral hydrogen channels are able to form in a subset of low-mass galaxies (≲1 × 108
M
⊙) that experience a burst of star formation (sSFR > 100 Gyr−1). Other extreme [O iii] emitters show weaker Lyα that is shifted to higher velocities (≃240 km s−1) with little emission near the line center. We investigate the impact the IGM is likely to have on these intrinsic line profiles in the reionization era, finding that the centrally peaked Lyα emitters should be strongly attenuated at z ≳ 5. We show that these line profiles are particularly sensitive to the impact of resonant scattering from infalling IGM and can be strongly attenuated even when the IGM is highly ionized at z ≃ 5. We compare these expectations against a new database of z ≳ 6.5 galaxies with robust velocity profiles measured with JWST/NIRSpec.
GRMHD Simulations of Accretion Structures with Different Angular Momentum Profiles
Authors: Bardiev Dilshodbek , Wang Yuhuan , Kološ Martin , Ahmedov Bobomurat 
Published: August 2024

Abstract
In this article, we explore the dynamics of accretion structures encircling spherically symmetric black holes, comparing three accretion disk models with distinct angular momentum profiles: (i) the geometrically thin Keplerian disk, (ii) the Fishbone–Moncrief torus; and (iii) the Polish Doughnut. Employing general relativistic magnetohydrodynamics simulations with the High Accuracy Relativistic Magnetohydrodynamics code, we investigate these three models, considering the magnetic field’s influence on the accretion disk angular momentum redistribution. We show that the magnetic field is a key factor in accretion disk structures, especially in regions with lower mass density. Our investigation verifies the well-established fact that the presence of a magnetic field significantly influences the accretion rate and its temporal variability.
