Published: December 2023

The issue of factual consistency in abstractive summarization has received extensive attention in recent years, and the evaluation of factual consistency between summary and document has become an important and urgent task. Most of the current metrics are adopted from the question answering (QA) or natural language inference (NLI) task. However, the application of QA-based metrics is extremely time-consuming in practice while NLI-based metrics are lack of interpretability. In this paper, we propose a cloze-based evaluation framework called ClozE and show its great potential. It inherits strong interpretability from QA, while maintaining the speed of NLI-level reasoning. We demonstrate that ClozE can reduce the evaluation time by nearly 96$\%$ relative to QA-based metrics while retaining their interpretability and performance through experiments on six human-annotated datasets and a meta-evaluation benchmark GO FIGURE\cite{gabriel2021go}. Finally, we discuss three important facets of ClozE in practice, which further shows better overall performance of ClozE compared to other metrics. The codes and models are released at https://github.com/Mr-KenLee/ClozE.
Multi-flavor quantum criticality

Published: December 2023

The electronic density of states, and, hence, the quasiparticle mass on the Fermi surface, is strongly enhanced through electronic correlations in quantum-critical metals [1, 2]. The nature of electronic correlations in such systems can be constrained by comparing different probes of the electronic density of states. Comparative studies in high-Tc superconductors present a significant challenge because of the masking effect of the superconducting phase [3]. In contrast, the normal state can be readily accessed in the unconventional superconductor CeCoIn5, because the energy scale associated with superconductivity is small [4]. Here we use thermal impedance spectroscopy [5] to simultaneously access the electronic density of states in CeCoIn5 in two independent ways; via the nuclear spin-lattice relaxation rate and via the electronic specific heat. We establish that the temperature- and magnetic field dependence of the nuclear spin-lattice relaxation rate is determined entirely by the electronic density of states on the Fermi surface, where mass enhancement is cut off at high magnetic fields. Surprisingly, the specific heat reveals excess entropy in addition to that associated with the density of states on the Fermi surface. The electronic nature of this excess entropy is evidenced by its suppression in the superconducting state. We postulate that a second “flavor” of boson generates the observed quantum critical physics beyond the mass renormalization on the Fermi surface in CeCoIn5. We suggest such a multi-flavor character for a broader range of quantum critical metals.
Television broadcasting of the Sumy region during the period of martial law: problems and challenges
Authors: Kyrylenko Oksana
Published: December 2023

Introduction. From the first day of Russia’s full-scale invasion of Ukraine, the majority of regional broadcasters and program service providers of Sumy Oblast found themselves in the zone of active hostilities. Therefore, the description of the work of border regional broadcasters during martial law is extremely relevant.
Relevance of the study. The proposed study will provide an opportunity to learn the practical experience of border regional TV broadcasters of Sumy Oblast in war conditions, to identify problem areas that need to be eliminated, and the reactions of the media community and the state to them.
Methodology. During the work on the research, a number of general scientific methods and techniques were used, including interviews with the heads of regional TV channels of Sumy Oblast, monitoring, content analysis, descriptive, analysis and synthesis.
Results. It was found that the majority of TV and radio companies and software service providers of the Sumy region work today in difficult financial and economic conditions, their activities are affected by such factors as a lack of personnel; danger during business trips; emotional burnout and anxiety disorders; loss of confidence in financial stability; end of grant support and inability to finance work; stoppage of the advertising market; attacks on websites; loss of competitive advantages in the media environment. In addition, the threat of a repeated attack by the Russian army from the north and north-east is not excluded; new intense attacks on critical infrastructure will lead to blackouts and the absence of communication and the Internet. Despite this, the TRC of the region showed considerable solidarity in the most acute period, did not stop broadcasting and continue to work. Although it is becoming more and more difficult to do this every day. Currently, private media survive on the principle: «Make money for salaries or close the company» The financial component comes to the fore, which is a dangerous signal. As for the Public Broadcaster, the reformation (creation of a system of regional HUBs) worsened the position of regional branches. Regional broadcasters on the ground are currently not associated as separate “players”. Therefore, under such conditions, regional television companies cannot be as efficient as possible and fully fulfill their task of providing citizens with high-quality information services.
Conclusions. The state already needs to think about the perspective of regional broadcasters’ functioning and their support, especially those broadcasters who work in border areas and are an informational outpost of Ukraine.

The inheritance of energy conditions: Revisiting no-go theorems in string compactifications
Authors: Bernardo Heliudson , Brahma Suddhasatwa , Faruk Mir Mehedi
Published: December 2023

One of the fundamental challenges in string theory is to derive realistic four-dimensional cosmological backgrounds from it despite strict consistency conditions that constrain its possible low-energy backgrounds. In this work, we focus on energy conditions as covariant and background-independent consistency requirements in order to classify possible backgrounds coming from low-energy string theory in two steps. Firstly, we show how supergravity actions obey many relevant energy conditions under some reasonable assumptions. Remarkably, we find that the energy conditions are satisfied even in the presence of objects which individually violate them due to the tadpole cancellation condition. Thereafter, we list a set of conditions for a higher-dimensional energy condition to imply the corresponding lower-dimensional one, thereby categorizing the allowed low-energy solutions. As for any no-go theorem, our aim is to highlight the assumptions that must be circumvented for deriving four-dimensional spacetimes that necessarily violate these energy conditions, with emphasis on cosmological backgrounds.

Planning frameworks, usually in the form of master plans, provide the direction for investment priorities necessary to achieve development objectives in many sub-Saharan African countries. Traditionally, master plans were developed using engineering methodologies with little stakeholder participation. There is little understanding of how master plans for sanitation infrastructure and services can be collaboratively designed. Through the application of a case study from Freetown, Sierra Leone, the paper proposes a framework for shifting infrastructure planning from conventional models to participatory, evidence-based methods. Findings highlight that the commitment of government and funding institutions created a sense of urgency and importance around sanitation issues and unlocked opportunities for increased financing and a better enabling policy and regulatory environment. Active engagement of the community and evidence-based decision-making ensured that the master plan aligned with the specific needs, preferences, and aspirations of all stakeholders. It was however challenging to use the principles of citywide inclusive sanitation (CWIS) for participatory planning because the implementing agencies and stakeholders lacked adequate capacity to do so. These findings hold significant implications for decision-makers, sanitation planners, and municipal authorities engaged in the development of sanitation master plans.
A comparative analysis of the methods of evaluating dependability using Big Data of complex system operation
Authors: Bursian E. Yu. , Prourzin V. A. , Prourzin O. V.
Published: December 2023

Aim. The paper aims to research the methods of evaluating dependability indicators based on the analysis of Big Data obtained in the course of monitoring the operation of technical systems and their components. A comparative analysis is performed of the efficiency of robust statistical methods of evaluating the dependability indicators of complex technical systems based on operation data.

Methods. The paper uses methods of mathematical statistics, specifically robust methods of evaluating the translation parameter of a noisy sample and numerical methods of statistical modeling. The authors consider five methods of evaluating the translation parameter: sample mean as a nonrobust method used for comparison; sample median as the simplest robust method of evaluating the translation parameter; two-stage evaluation procedure with truncation of outliers according to the three sigma rule; two-stage evaluation procedure with truncation of outliers using Tukey’s box-and-whisker plot; Huber’s robust method. The comparative analysis of the methods of evaluating system dependability indicators was conducted by means of statistical modeling in the R statistical computation package. Five distribution laws for generating an element’s time-to-failure and recovery time samples were considered: exponential distribution, Weibull distribution, log-normal distribution, gamma distribution and uniform distribution.

Results. Statistical analysis of Big Data associated with the operation of technical systems is complicated by the heterogeneity and noisiness of such data, as well as the presence of errors and outliers of varied nature. That is primarily due to the varied loads and operating conditions of each object. Herein this problem is examined as regards the problem of evaluating the dependability indicators of a structurally complex monotonic system with independent element recovery. The paper examines methods of rejecting anomalous data and robust evaluation of the sample position parameter and performs a comparative analysis of the efficiency of such methods for various distribution laws. It is shown that robust methods of evaluation enable significantly higher accuracy as compared to the standard sample mean. The two-stage procedure based on the truncation of outliers and Tukey’s box-and-whisker plot proved to be the most efficient.

Conclusions. The paper’s findings allow improving the accuracy of evaluation of dependability indicators based on complex technical system operation data. They can be used in Big Data processing and complex system dependability theory.

Abstract. Tungsten (W) exhibits excellent thermal properties such as the highest melting point among the metallic elements, however, its engineering usefulness is limited due to the recrystallization embrittlement. Aiming at solving the recrystallization embrittlement, TFGR (Toughened Fine-Grained Recrystallized) W-1.1% TiC that exhibits high bending strength of 3.2~4.4 GPa and appreciable bend ductility at room temperature was developed. In collaboration with KEK, Sunric Co., Ltd., and Metal Technology Co. Ltd. (MTC) is upgrading the development phase for the engineering applicability of TFGR W-1.1TiC to increase the scale of manufacturing, to achieve mass production, and improve heat resistance and toughness. Reduction of gas-impurities such as oxygen and nitrogen is one of the essential factors in the manufacturing process. In this presentation, a fundamental study to understand outgassing behavior inside the HIP capsule will be introduced.
Powder Metallurgy HIP and Extrusion Study of FeCrAl Alloy for Accident Tolerant Fuel Cladding
Authors: Huang S.
Published: December 2023

Abstract. Powder metallurgy HIP and extrusion processing conditions were investigated in a FeCrAl alloy (Fe-Cr-Al-Mo based PM-C26M) for accident tolerant fuel cladding applications. The powder size range, HIP temperature (900 ~ 1100°C), HIP time (2 hours vs. 4 hours) were varied in lab-scale experiments, using argon gas atomized powder. The resulting density, grain size distribution, and retained plastic strain were characterized to recommend the HIP condition with full consolidation, fine grain size for formability, and good powder economics. The subsequent extrusion process was also studied in the temperature range of 950 ~ 1050°C as well as post annealing conditions. Based on the microstructure evaluation, sensitivity of HIP and extrusion process parameters were better understood.
Modelling of Powder Filling of HIP Canisters
Authors: Chung S.
Published: December 2023

Abstract. Hot-isostatic pressing (HIPing) of powders is achieved by placing them inside a canister, which is then evacuated and sealed. Canister filling is a critical step. Consistency in powder packing in the canister and increases in packing density will improve process efficiency and the predictability of HIP canister collapse, leading to less wastage. Understanding the effect of powder morphology, properties and characteristics on the can filling process and subsequent compaction is vital to optimizing canister design and the filling system. Conventionally, this has involved conducting numerous costly and time-consuming trial-and-error experiments. Computational modelling offers an alternative optimization path. Discrete element method (DEM) simulation of a powder filling process has been developed by GRI Inc. and its application to the US Department of Energy’s radioactive Idaho calcine powders has been investigated. A comprehensive analysis of a non-radioactive simulant powder has been conducted. A DEM model was developed with validation of the model using experimental data obtained from the filling system development program.
HIP Modeling and Design of Large Complex Shape Parts Close to the Size of the HIP Furnace Accounting Capsules Manufacturing Technology and their Movement Inside it During the Cycle
Authors: Seliverstov D.
Published: December 2023

Abstract. The size of the parts needed to be HIPed for critical applications, especially in nuclear, is growing and very often the HIP capsules become so large that they take not only the entire diameter of the HIP furnace, but almost all its volume. Often, these parts weigh thousands of pounds, do not have axial symmetry and cannot stand by themselves in the furnace requiring complex shape supporting frames. For such parts additional problems need to be solved in the HIP tooling design and HIP process itself due to: (1) difficulties in maintaining dimensional accuracy, (2) non-uniform temperature field inside the HIP during heating and ramping the pressure, (3) different mechanical properties in HIP capsule elements and (4) HIP capsule movement during deformation inside the supporting frame. HIP modeling allows to approach these problems. Several examples of the solutions allowing HIPing of complex shape non-symmetrical parts up to 70" in size are analyzed.

Authors: Berment-Parr I.
Published: December 2023

Abstract. Polymer Electrolyte Membrane (PEM) electrolyzers are a key to the future of global hydrogen production. However, current systems rely on titanium components manufactured through energy and resource intensive processes which make up a large proportion of the overall capital cost of an electrolyzer stack. In this work circular economy principles have been applied to investigate net shape powder manufacturing routes for these titanium plate and porous film components. Approaches include (1) direct HIP of waste stream materials such as un-melted titanium sponge fines or subtractive machining swarf (2) net shape manufacturing of complex geometries using innovative dissolvable salt space holding inserts (3) in-situ nitriding methods (4) streamlining a large number of processing stages within the existing supply chain. In order to assess the environmental impact of the proposed manufacturing routes an embodied carbon analysis was conducted comparing the emissions potentially generated via this powder process versus the traditional supply chain.

Published: December 2023

Abstract. Powder Metallurgy - Hot Isostatic Pressing (PM-HIP) is considered a key technology for component fabrication. By offering near-net shape forming, long lead-time components can be delivered quicker and more efficiently, ultimately supporting on-time construction of nuclear components and structures. To this end, ferrous (A508 Grade 4N) and nickel-base alloys (A600) have been examined in the consolidated PM-HIP condition to assess the mechanical behavior as well as similarity to their wrought/forged counterparts. In this study, various aspects of the PM-HIP process were explored from the powder production to the consolidated material and eventual heat treatment to develop a greater understanding of optimized mechanical properties of PM-HIP material. Trends in processing conditions and various heat treatments were correlated to the performance of each material and related to the wrought counterpart.

Authors: Beamer C.
Published: December 2023

Abstract. Recent advancements in hot isostatic pressing (HIP) equipment now offer the ability to integrate HIP and heat treatment in the HIP furnace with the aid of controllable high-speed cooling and in-HIP quenching. This approach not only offers improvement in productivity but provides a path to prevent anomalies during heat treatment including thermally induced porosity (TIP) and part quench cracking or distortion. This manuscript will cover the approach of High Pressure Heat Treatment (HPHTTM) applied to SLM Solutions laser powder bed fusion (L-PBF) printed high strength aluminum alloy F357. Microstructure, tensile properties, and part distortion are evaluated. The results capture a post process method making it possible to prevent hydrogen blistering, mitigate defects present in the L-PBF material, offer strength properties exceeding that of MMPDS cast properties, and minimize geometric distortion of complex part geometries.

La presente investigación tiene como objetivo demostrar que el derecho humano a la doble instancia, establecido en el artículo 8o., fracción 2, inciso h), de la Convención Americana sobre Derechos Humanos, que en esencia implica el derecho a recurrir un fallo ante un tribunal o juez superior, debe ser instituido dentro del procedimiento laboral mexicano. No obstante, la existencia del juicio de amparo directo como último medio de impugnación del juicio laboral no es el recurso a que hace referencia la jurisprudencia de la Corte Interamericana de Derechos humanos, por lo que, ante las recientes reformas laborales constitucionales y legales que no contemplan medio de impugnación en el procedimiento del trabajo, es dable proponer la implementación de un doble grado de jurisdicción, a efecto de respetar los derechos humanos procesales y eficientar la administración de justicia.

Published: December 2023

Taking into consideration the increasing relevance that environmental constitutionalism has currently assumed, the aim of this article is to critically analyze the constitutional protection of the environment in the Amazonian countries. It seeks to identify whether there is a common language among the constitutions concerning environmental protection in order to improve international cooperation. The hypothesis states that: 1) the Amazon environmental constitutionalism follow the epistemological opening of contemporary constitutionalism, by assimilating innovations in each new constitution; and, 2) the constitutions establish normative elements for the improvement of international cooperation in the region. The reflection is grounded on the field of comparative constitutional law, in dialogue with international constitutional law and constitutional theory, in a functional-structural perspective, focusing the “legislative” formant.

Shooting Simulator «Inhibitor»: Mathematical Supportof Fire Range and Shielding
Authors: Egorov S. F.
Published: December 2023

Mathematical support for constructing the relief of a shooting range from an image with support for the height and range of each point and taking into account the screening of targets by folds terrain for tactical optical-electronic simulator of the small arms 'Inhibitor' developed at Institute of mechanics UdmFRC UB RAS and at Computer facilities department of Kalashnikov ISTU jointly with JSC «Kalashnikov Concern» was described. The tactical and technical task for the functional capabilities of implementing the relief of the shooting range is given: hills, ravines, mountains at a distance of up to 2 km in the sector up to 60°, shielding targets with folds of the area. A relief model is proposed in the form of a bilinear interpolated matrix of heights with a pitch of 10 m, and an editor is developed that allows interactively specifying range boundaries and terrain height along the front on the image of the shooting range. Screening the visibility of targets by folds of the terrain is implemented using the central projection of all relief profiles for a single workplace of shooters, and for the implementation of trenches, a mechanism for the height of the target above the surface of the shooting range is proposed, which optimizes the 'quality-speed' ratio. Studies of the «projector-screen-observer» system showed the presence of factors of errors in the virtual shooting range, some of which are of a fundamental nature, and the rest can be compensated for by the regression model of the target point recorder and taking into account its cumulative error by reducing the tabular ballistic dispersion of simulated shots. Based on the prospects for further research and development of electronic shooting simulators and thanks to the improvement of computing tools and the development of software graphics libraries, it is necessary to expand the functionality of the simulators and reduce the cost, which means to increase competitiveness, for example, improving the realism of simulating the terrain of the shooting range with screening of targets by folds of the terrain.
Comparative Study of Methods to Present the Results of Texture Analysis of Polycrystalline Materials
Authors: Mokrova S. M. , Milich V. N.
Published: December 2023

It is necessary to use various methods of texture analysis at all stages of the technological processing of metals and alloys in order to select the optimal parameters for processing materials and obtain the necessary properties of final products. The article deals with the methods of presenting the results of texture analysis. Usually, the texture of a material is described by several preferred texture components, where the way of representation depends on the given task. The textural components combine the orientations of crystals having similar position in the sample volume. The results of texture analysis are the distribution of orientations relative to the base coordinate system. Orientation is described by four parameters: three coordinates in space and intensity, which is defined as the probability of occurrence of this orientation in the sample. Methods for representing the orientation of a single crystal by several descriptors: Euler angles, Miller indices, Rodrigues vectors, etc., each describing the rotation of the crystal coordinate system relative to the selected sample coordinate system, are given in the article. The formulae for the transition from one descriptor to another are given. The texture calculation algorithms depend on the way orientations are represented. Some representations are more convenient to use for calculations, others - for visualization and data processing. In particular, the use of the Rodrigue space allows not only to visualize the orientation cloud, but also to form textural components in it with a given accuracy by clustering. Variants of the analysis result presentation are shown in a model example. The textural components computed with high accuracy are displayed in the spaces of Euler angles and Rodrigues vectors. The orientation distributions are shown as a histogram and a pole figure {001}.
Multichannel Generator Time-To-Pulse Converter of the Telemetry Temperature Measurement System
Authors: Kulikov V. A. , Syakterev V. N. , Syaktereva V. V. , Varlamova D. M.
Published: December 2023

The article considers the multichannel time-to-pulse intermediate converter as a part of telemetric temperature measurement system. The principle of operation is based on the use of aperiodic transient in a first-order circuit formed by resistance temperature device and capacitor. Switching of resistance temperature device in the process of temperature measurements is carried out by MIS keys (metal-insulator-semiconductor) according to the signal from the output of the circuit, and the allocation of the output information interval is carried out by a voltage comparator. The article illustrates an electric circuit of a time-to-pulse converter. Based on the equivalent scheme, the main metrological characteristics were obtained by calculation, namely, the dependences of the sensitivity of the output value of the converter to changes in the parameters of the circuit elements expressed in terms of temperature. The scheme of a time-to-pulse converter with an optical output, designed for use with semiconductor resistance temperature devices was experimentally investigated. Variants of multichannel converters for 7 and 15 measuring channels are implemented. Digital elements of the MIS-type (metal-insulator-semiconductor) are used. Information about the temperature at the output of the converters was encoded in the duration of 128 periods of pulse signals, which ensured reliable of information intervals in the receiving part of the equipment. A laboratory tester with an optoelectronic input was used as a receiver of optical pulses. The duration of the information intervals was measured by an industrial measuring device with a resolution of 10 billiseconds. The experimental and rated characteristics of the conversion and the dependence of the conversion error on the supply voltage, operating temperature and resistance of primary thermal converters are presented. It is established that in terms of the main operational parameters, a generator-type time-to-pulse converter is not inferior to a circuit with external excitation. At the same time, the generator converter is less sensitive to the errors of the comparator in terms of electrical bias and speed. The use of a multichannel generator time-to-pulse converter is advisable in telemetric temperature measurement systems when transmitting information in a communication channel during the duration of the period of information, in particular, optical pulses.

The article discusses the features of software and hardware complex development to monitor the efficiency of employees by means of an ESP8266 microcontroller and video cameras with a YOLOv8 neural network that meets the requirements of a 'smart shop'. The purpose of this study is to justify and evaluate the working concept of the created software and hardware complex in the form of a working prototype. Examples of current developments of similar monitoring systems realized within the paradigm of the Internet of Things, are given. However, the systems found in international practice focus on processing images of moving personnel only and do not analyze the technical parameters of the equipment this personnel work on. This study attempts to overcome this limitation. A schematic diagram of the system operation consisting of four key modules has been developed: a data collection module from machine-tools, an employee identification module, a primary data processing module, a web server with software application to manage the entire system in real time. The MQTT (Message Queuing Telemetry Transport) protocol is used for communication between devices and the server in the designed system to provide quality of data transmission under conditions of channel bandwidth limitations. Combined analysis of data from both machine-tools (control of the load of the electric motor) and the movement of workers in the space of the production room is proposed within the concept of developing such systems for the first time. Evaluation tests on the monitored data showed the operability of the entire complex, the problem of object automatic detection in the camera image flow and their location within the coordinate system of the production room was solved.

Published: December 2023

Mathematical support of target layout with pre-scaling during storage and mixing of target image boundaries is described when displaying on a shooting range for the optical-electronic shooting simulator 'Inhibitor' developed at Institute of mechanics UdmFRC UB RAS and at Computer Engineering department of Kalashnikov ISTU jointly with JSC «Kalashnikov» Concern». The tactical and technical task for the implementation of the target layout is given: support for all targets from the Shooting Course and realistic targets, the angular dimensions of objects on the screen must correspond to the real ranges to them, and the speed of visualization algorithms allows simultaneously displaying at least 32 targets with a frequency of at least 25 frames/s. When developing mathematical support, the BMP format for storing TrueColor images with the scale of 1 pixel = 1cm2 was chosen, scaling targets to speed up further processing and the obligatory mixing of object-background border colors when displaying fractional coordinate support with pixel fractions of greatly reduced targets on the screen (so a thoracic target 50 cm wide at a distance of 100 m should be 12.8 points wide, while at a distance of 600 m - 2.13 points only) was emphasizes. The carried out studies of mathematical support performance for the target layout images formation confirmed compliance with the tactical and technical task requirements and recommended a pre-scaling factor of 0.5 (1:2) for optimal «quality-performance» ratio. Based on the prospects for further research and development of electronic shooting simulators and due to the improvement of computing tools and the development of software graphics libraries, it is necessary to expand the eficiency of simulators and reduce costs, which means to increase competitiveness, for example, by increasing the target layout display realism.
A Study on Microstrip Array Antenna with FSS for Next Generation Cellular Communication
Authors: Jain Palak
Published: December 2023

Abstract: Fifth-generation wireless, often known as 5G, is the next version of cellular technology and is intended to provide major improvements to the speed and responsiveness of wireless networks. In addition, the increased bandwidth and improved antenna technologies that come with 5G make it possible for a significant increase in the quantity of data that can be transmitted via a wireless network. In order to build a successful next-generation cellular communication system in the terahertz (THz) regime, it is necessary to create high-directivity antennas, which will enable the signal to travel further than 0.1 km. This will allow the system to function effectively. Concurrently, large bandwidth antennas should be designed in order to facilitate the information's transmission

Authors: Shende Pranay
Published: December 2023

Abstract: A Time-based One-Time Password (TOTP) validator is interposed between a principal and a network service. The validator interacts with a mobile application (app) on the mobile device associated with the principal to` dynamically supply a validator secret. The secret and, perhaps, other information are processed by the app to generate a TOTP when the principal attempts to access a protected resource of the network service. The validator independently generates the TOTP and compares the app generated TOTP, and on a successful match, a principal's access device is redirected for access to the protected resource.
