THEORETICAL APPROACHES TO THE SELECTION OF DETECTION METHODS OF EXPLOSIVE DEVICES IN ENVIRONMENTS THAT CONCEAL THEM, ADVANTAGES AND DISADVANTAGES
Authors: Krivtsun V. , Lyashenko V. 
Published: April 2024

The results of the analysis of trends in the development of armed struggle indicate the ever-increasing role of the use of mine weapons. At the same time, there is a significant imbalance between the development of mine weapons and detection means, which in turn causes a number of problematic issues in demining. It is noted that due to the aggression of the russian federation, Ukraine has become the most mined country in the world. In addition to the problem of demining the contaminated territory with explosive objects, the issue of reconnaissance of the area for mines and making passages in enemy minefields has become acute.
The paper analyzes the demining process, identifies the factors that influence it, and presents the main demasking factors of explosive objects, as well as the performance of terrain demining tasks. Taking into account these features, theoretical approaches to the detection and identification of explosive objects based on various physical principles are considered. An analysis of the use of the main methods of detection and identification of explosive objects is carried out, their advantages and disadvantages are determined.
Based on the analysis of theoretical approaches, a generalized characterization of the main methods of detecting explosive objects is given. It is noted that, taking into account the experience of performing demining tasks in the war of the russian federation against Ukraine, the main methods of searching for explosive objects are contact, mechanized, induction, optical, thermal and in some cases biophysical. Today, the use of advanced explosive detection methods is limited by the need to solve technical problems to reduce the number of false signals. The paper notes that in order to increase the efficiency of the process of detecting explosive objects and ensure proper safety, it is advisable to combine detection methods, as well as combine them with remotely controlled (robotic) means, as well as UAVs.
TEMPERATURE ERROR OF THE MEANS OF MEASURING THE GEOMETRIC CHARACTERISTICS OF BORES OF FIREARMS: MATHEMATICAL MODEL AND QUANTITATIVE EVALUATION
Authors: Kriukov O. , Mihura O. 
Published: April 2024

The work is devoted to the construction of mathematical models and quantitative assessment of the components of the temperature error of a laser triangulation sensor for measuring the geometric characteristics of bores of firearms.
The existence of problematic issues in the field of evaluating the metrological characteristics of laser triangulation means for technical diagnostics of firearms barrel channels is highlighted. An analysis of publications
on the evaluation of the error of a laser triangulation sensor caused by the influence of ambient temperature is carried out, and known approaches to their mathematical modeling are considered. The need to develop mathematical models of the components of the temperature error of a laser triangulation sensor and to quantify this error is substantiated.
The parameters of the optical scheme of the laser triangulation sensor, whose deviation from their nominal (calculated) values will affect the conversion function, are determined. It is shown that the presence of a temperature error during the processing of measurement information will be perceived as an apparent change in the measured value with a constant input signal.
On the basis of algebraic transformations of expressions reflecting the relationship between the output value of a laser triangulation sensor and deviations of the optical circuit parameters from their nominal values, mathematical models of the temperature error components are obtained and presented in the form of error component limits at the input of the measuring instrument. The expressions for determining the confidence limits of the total temperature error, taking into account the correlation between its components, are substantiated.
A quantitative assessment of the temperature error for the characteristic combinations of weapon parameters (for four ranges of barrel calibers) in the range of ambient temperature variations inherent in the region where measurements are made is carried out. The results of the quantitative evaluation are presented in the form of graphs of the dependence of the limits of relative and absolute temperature errors on temperature and on the increase in the bore radius in the measurement range. The data obtained were analyzed, the peculiarities of the dependencies were determined, and conclusions were drawn about the compliance of the temperature error characteristics of the measuring instrument with the requirements for its accuracy.

Kepala Desa sebagai lembaga pemerintah terkecil diberikan kewenangan oleh pemerintah dalam mewujudkan otonomi desa salah satunya diwujudkan dengan pemberian kewenangan pembangunan secara lokal-partisipatif kepada desa. Namun dalam praktiknya, kewenangan yang telah diberikan tersebut justru dimanfaatkan oleh sebagian kepala desa untuk korupsi. Kesadaran tentang korupsi dan dampaknya yang menghambat pembangunan dan kesejahteraan masyarakat belum dirasakan oleh Kepala Desa dengan masih banyak Kepala Desa yang terjerat kasus korupsi. Atas permasalahan tersebut Tim Pengabdian Masyarakat Fakultas Ilmu Sosial Universitas Negeri Surabaya melakukan Upaya Pendidikan anti korupsi kepada pada Kepala Desa untuk memberikan pemahaman terhadap peraturan-peraturan tentang korupsi dan akibatnya. Hasil dari kegiatan ini sangat bermanfaat dan mampu memberikan pengetahuan lebih kepada Kepala Desa untuk lebih akuntabel dan transparan dalam membangun desa

The Sustainable Development Goals (SDGs) represented a key landmark in collaboration and shared agenda-setting to address global challenges across scales and geographies. However, despite initial optimism that measurable goals would support accountability and transparency in development, progress towards realising goals has been mixed. Global development agendas increasingly face challenges from the intensification of climate change, the return of populism and ethnonationalism, and a deepening of inequalities at intra- and inter-national scales.
This article interrogates the priorities that must inform a critical post-SDG development agenda. To think towards this, we first explore three questions of the development agenda: 1) can development be sustainable? 2) Can development be delivered through markets? And 3) can development be ‘global’? To address these tensions and take a first step towards a more critical post-2030 agenda, we call for a focus on spatialities, multiplicities and historicities of development.

Abstract
Spectroscopic observations of nine cataclysmic variables that have been postulated to contain magnetic white dwarfs were obtained to further characterize their classifications, orbital parameters, inclinations, and/or accretion properties. Zwicky Transient Facility (ZTF) and Transiting Exoplanet Survey Satellite (TESS) data were also used when available. This information enables these systems to be useful in global population and evolution studies of close binaries. Radial velocity curves were constructed for eight of these systems, at various states of accretion. High-state spectra of ZTF0548+53 reveal strong He ii emission, large radial velocity amplitudes, as well as cyclotron harmonics yielding a magnetic field strength of 50 MG, confirming this as a polar system. Analysis of TESS data reveals an orbital period of 92.1 minutes. High-state spectra of SDSS0837+38 determine a period of 3.18 hr, removing the ambiguity of periods found during the low state, and showing this is a regular polar and not a pre-polar system. The ZTF light curve of CSS0026+24 shows a total eclipse with a period of 122.9 minutes, and features indicative of two accretion poles. A new, remarkably large spin-to-orbit ratio is found for ZTF1631+69 (0.61), making it, along with 2011+60 (=Romanov V48), likely stream-accreting intermediate polars. ZTF data reveal the presence of ∼2 mag low states in ZTF1631+69, and along with McDonald Observatory 2.1 m and TESS light curves, confirm a grazing eclipse that is deepest at a narrow subset of beat phases. The TESS data on PTF12313+16 also indicate a partial eclipse. Analysis of ZTF data on SDSS1626+33 reveals a period of 3.17 hr and suggests the presence of a partial eclipse.
Was There a 3.5 keV Line?
Authors: Dessert Christopher , Foster Joshua W. , Park Yujin , Safdi Benjamin R. 
Published: April 2024

Abstract
The 3.5 keV line is a purported emission line observed in galaxies, galaxy clusters, and the Milky Way whose origin is inconsistent with known atomic transitions and has previously been suggested to arise from dark matter decay. We systematically reexamine the bulk of the evidence for the 3.5 keV line, attempting to reproduce six previous analyses that found evidence for the line. We only reproduce one of the analyses; in the other five, we find no significant evidence for a 3.5 keV line when following the described analysis procedures on the original data sets. For example, previous results claimed 4σ evidence for a 3.5 keV line from the Perseus cluster; we dispute this claim, finding no evidence for a 3.5 keV line. We find evidence for background mismodeling in multiple analyses. We show that analyzing these data in narrower energy windows diminishes the effects of mismodeling but returns no evidence for a 3.5 keV line. We conclude that there is little robust evidence for the existence of the 3.5 keV line. Some of the discrepancy of our results from those of the original works may be due to the earlier reliance on local optimizers, which we demonstrate can lead to incorrect results. For ease of reproducibility, all code and data are publicly available.
Modeling the Reverberation Response of the Broad-line Region in Active Galactic Nuclei
Authors: Rosborough Sara A. , Robinson Andrew , Almeyda Triana , Noll Madison 
Published: April 2024

Abstract
The variable continuum emission of an active galactic nucleus (AGN) produces corresponding responses in the broad emission lines, which are modulated by light travel delays, and contain information on the physical properties, structure, and kinematics of the emitting gas region. The reverberation mapping technique, a time series analysis of the driving light curve and response, can recover some of this information, including the size and velocity field of the broad-line region (BLR). Here we introduce a new forward-modeling tool, the Broad Emission Line MApping Code, which simulates the velocity-resolved reverberation response of the BLR to any given input light curve by setting up a 3D ensemble of gas clouds for various specified geometries, velocity fields, and cloud properties. In this work, we present numerical approximations to the transfer function by simulating the velocity-resolved responses to a single continuum pulse for sets of models representing a spherical BLR with a radiatively driven outflow and a disklike BLR with Keplerian rotation. We explore how the structure, velocity field, and other BLR properties affect the transfer function. We calculate the response-weighted time delay (reverberation “lag”), which is considered to be a proxy for the luminosity-weighted radius of the BLR. We investigate the effects of anisotropic cloud emission and matter-bounded (completely ionized) clouds and find the response-weighted delay is only equivalent to the luminosity-weighted radius when clouds emit isotropically and are radiation-bounded (partially ionized). Otherwise, the luminosity-weighted radius can be overestimated by up to a factor of 2.
The NuSTAR View of Perseus: The Intracluster Medium and a Peculiar Hard Excess

Published: April 2024

Abstract
As the brightest galaxy cluster in the X-ray sky, Perseus is an excellent target for studying the intracluster medium (ICM), but until recently, its active galactic nucleus (AGN) made studies of the diffuse emission near its center nearly impossible to accomplish with NuSTAR, due to the extended wings of NuSTAR's point-spread function. The development of a new open-source software package—nucrossarf—now allows the contribution from point and diffuse sources to be modeled so that scattered light from the AGN can be accounted for. Using this technique, we present an analysis of diffuse hard X-ray (3–25 keV) emission from the ICM using three archival NuSTAR observations of the Perseus cluster. We find a ∼10% excess of emission beyond 20 keV not describable by purely thermal models. By performing similar analyses of AGNs in archival observations, we have characterized the systematic uncertainty of the modeled AGN contribution to be 3.4%. However, in order to explain the excess, the total scattered AGN emission would have to be 39% stronger than we have measured. We test physical explanations for the excess, such as diffuse inverse-Compton emission potentially originating from the radio mini-halo, but we determine that none of the models are compelling. An upper limit on the inverse-Compton flux (≤1.5 × 10−11 erg s−1 cm−2) and a corresponding lower limit on the global magnetic field strength (≥0.35 μG) are derived. We discuss the potential origin and implications of the excess and present our characterization of the nucrossarf systematic uncertainty, which should be useful for future work.
The Molecular Exoskeleton of the Ring-like Planetary Nebula NGC 3132

Published: April 2024

Abstract
We present Submillimeter Array (SMA) mapping of 12CO J = 2 → 1, 13CO J = 2 → 1, and CN N = 2 → 1 emission from the ring-like planetary nebula NGC 3132, one of the subjects of JWST Early Release Observation near-infrared imaging. The ∼5″ resolution SMA data demonstrate that the Southern Ring’s main, bright, molecule-rich ring is indeed an expanding ring, as opposed to a limb-brightened shell, in terms of its intrinsic (physical) structure. This suggests that NGC 3132 is a bipolar nebula viewed more or less pole-on (inclination ∼15°–30°). The SMA data furthermore reveal that the nebula harbors a second expanding molecular ring that is aligned almost orthogonally to the main, bright molecular ring. We propose that this two-ring structure is the remnant of an ellipsoidal molecular envelope of ejecta that terminated the progenitor star’s asymptotic giant branch evolution and was subsequently disrupted by a series of misaligned fast, collimated outflows or jets resulting from interactions between the progenitor and one or more companions.
Is the Radio Source Dipole from NVSS Consistent with the Cosmic Microwave Background and ΛCDM?
Authors: Cheng Yun-Ting , Chang Tzu-Ching , Lidz Adam 
Published: April 2024

Abstract
The dipole moment in the angular distribution of the cosmic microwave background (CMB) is thought to originate from the doppler effect and our motion relative to the CMB frame. Observations of large-scale structure (LSS) should show a related “kinematic dipole” and help test the kinematic origin of the CMB dipole. Intriguingly, many previous LSS dipole studies suggest discrepancies with the expectations from the CMB. Here, we reassess the apparent inconsistency between the CMB measurements and dipole estimates from the NVSS catalog of radio sources. We find that it is important to account for the shot noise and clustering of the NVSS sources, as well as kinematic contributions, in determining the expected dipole signal. We use the clustering redshift method and a cross-matching technique to refine estimates of the clustering term. We then derive a probability distribution for the expected NVSS dipole in a standard ΛCDM cosmological model including all (i.e., kinematic, shot noise, and clustering) dipole components. Our model agrees with most of the previous NVSS dipole measurements in the literature at better than ≲2σ. We conclude that the NVSS dipole is consistent with a kinematic origin for the CMB dipole within ΛCDM.
