Approximating Bribery in Scoring Rules
Authors: Keller Orgad , Hassidim Avinatan , Hazon Noam 
Published: June 2022

The classic bribery problem is to find a minimal subset of voters who need to change their vote to make some preferred candidate win.We find an approximate solution for this problem for a broad family of scoring rules (which includes Borda and t-approval), in the following sense: if there is a strategy which requires bribing k voters, we efficiently find a strategy which requires bribing at most k + Õ(√k) voters. Our algorithm is based on a randomized reduction from bribery to coalitional manipulation (UCM). To solve the UCM problem, we apply the Birkhoff-von Neumann (BvN) decomposition to a fractional manipulation matrix. This allows us to limit the size of the possible ballot search space reducing it from exponential to polynomial, while still obtaining good approximation guarantees. Finding the optimal solution in the truncated search space yields a new algorithm for UCM, which is of independent interest.
Syntax-Directed Attention for Neural Machine Translation

Published: June 2022

Attention mechanism, including global attention and local attention, plays a key role in neural machine translation (NMT). Global attention attends to all source words for word prediction. In comparison, local attention selectively looks at fixed-window source words. However, alignment weights for the current target word often decrease to the left and right by linear distance centering on the aligned source position and neglect syntax distance constraints. In this paper, we extend the local attention with syntax-distance constraint, which focuses on syntactically related source words with the predicted target word to learning a more effective context vector for predicting translation. Moreover, we further propose a double context NMT architecture, which consists of a global context vector and a syntax-directed context vector from the global attention, to provide more translation performance for NMT from source representation. The experiments on the large-scale Chinese-to-English and English-to-German translation tasks show that the proposed approach achieves a substantial and significant improvement over the baseline system.

DETERMINATION OF EMERGENCY REGIMES OF ELECTRIC MOTORS BY MEANS OF MODERN SYSTEMS OF DIAGNOSING THEIR CONDITION
Authors: Zakladnyi O. 
Published: June 2022

Electric motors are usually designed for a service life of 15… 20 years without major repairs, provided they are properly operated. Proper operation means operation in accordance with the nominal parameters specified in the passport data of the motor. However, in practice there is a significant deviation from the nominal modes of operation. These are, first of all, low quality of supply voltage and violation of rules of technical operation: technological overloads, environmental conditions (high humidity, temperature), decrease in insulation resistance, cooling disorders.
The consequence of such deviations are emergency modes of operation of electric motors. In some subsectors of the industry, the accident rate of electric motors ranges from 20 to 50% per year. Failure of the motor leads to severe accidents and significant material damage due to downtime, the cost of troubleshooting and repair of the failed motor. Repair of an electric car with a capacity of 1 kW costs 550-700 UAH. To estimate the cost of repairing a more powerful machine, you need to multiply this figure by the engine power. In addition, operation in emergency modes leads to increased energy consumption and increased reactive power consumption.
One of the promising types of protection against emergencies is the use of modern diagnostic systems with the function of monitoring the signs of emergencies. Therefore, the urgent task is to eliminate the shortcomings of protection devices through the use of modern intelligent systems for diagnosing their condition.
The task is to determine the set of diagnostic features of emergency electric modes of induction motors for the application of these features in the systems of functional diagnostics of energy and technical condition of the engine and increase the reliability of establishing the characteristic types of damage.
The article considers a set of signs of emergency electrical modes for different types of damage to induction motors. These features can be used in modern systems for diagnosing energy efficiency and technical condition of electromechanical systems, which can also perform the function of protecting electric motors from emergency modes.
PROBLEMS OF MODELING IN-VESSEL SEVERE ACCIDENT PHASE
Authors: Onyshchuk Y. , Klevtsov S. 
Published: June 2022

The process of a severe accident at a nuclear power plant is characterized by its complexity, versatility and wide relationships. When modeling the in-vessel phase of a severe accident, there are significant uncertainties, primarily related to the movement of materials of the destroyed core to the lower part of the reactor vessel, as well as its subsequent heating and accompanying high-temperature physical processes. A detailed comprehensive study of these processes will allow us to reliably predict the dynamics of a severe accident and correctly determine the time of failure of the reactor vessel and justify more effective actions of personnel in managing severe accidents and emergency response.
The article presents an analysis of the course of a severe accident, identifies and analyzes the main phases of the in-vessel phase of a severe accident. The analysis of processes and phenomena characteristic of these phases is carried out. The main uncertainties that arise when modeling the processes of a severe accident within the reactor vessel are considered. To eliminate/reduce uncertainty, an approach to conjugate severe accident modeling using the ANSYS CFX CFD code and the RELAP5/Mod 3.2 system thermohydraulic code is proposed.

Authors: Denysiuk S. , Melnychuk H. , Cherneshchuk І. , Lysyi V. 
Published: June 2022

The business model of energy as a service (Energy-as-a-service, EaaS) is considered as a direction of development of the concept of 3D (Decarbonization, Decentralization, Digitalization) and the conceptual model of the Internet of energy. At the same time, EaaS is formed in the form of a "package" service model, in which the customer is provided with hardware and software and energy services. EaaS solutions should include consumption management and energy efficiency services, promote the introduction of renewable energy sources (RES) and other decentralized energy sources, and optimize the balance between supply and demand in the electricity market. EaaS is shown to be a broad term for service-driven business models with innovative potential to transform the energy industry
To assess the specifics of EaaS application to Microgrid, the construction and operation of Microgrid as a local power system or power supply system, which is a technological complex consisting of generation facilities (energy sources), energy flexibility sources and electricity consumers, which are collected under a single management ensuring the most efficient and consumer-friendly energy supply. It is determined that the technological guarantee of the efficiency of modern Microgrid is the ability to integrate and optimally combine different energy sources and flexibility, as well as the presence of a single control loop that allows the best use of these sources.
Smart Grid as a Service (SGaaS) based on Service-Oriented Architecture is presented. The SGaaS hierarchical architecture provides a promising three-tier architecture that includes an intelligent network level for global optimization, such as minimizing global protection or global costs, a level of coordination to maintain reliability and security in the Smart Grid, and a Microgrid level to monitor end-user device status.
The implementation of the EaaS and SGaaS mechanisms has stimulated the development of Microgrid as a Service (MaaS) - as a service that offers the deployment of Microgrid, reducing the initial cost of investment and complexity. MaaS has been identified as a new flagship funding mechanism that allows organizations to deploy Microgrid without any prior investment, as a solution that does not require advance capital for energy consumers and focuses on results such as on-site energy. MaaS mechanisms offer customers more control over their energy needs, enabling them to increase the sustainability and reliability of their energy supply, balance energy use, achieve clean energy goals and explore other innovative products and services.
HEAT TRANSFER IN COIL HEAT EXCHANGERS WITH VARYING GEOMETRIC CHARACTERISTICS
Authors: Tuz V. , Lebed N. , Lytvynenko M. 
Published: June 2022

Coil-type heat exchangers are widely used in power industry and medical and electronic technology due to the relatively simple design of their basic elements, low operating costs, reliability and long service life. The process of designing the devices with coil heat exchangers requires choosing the tube surface configuration and taking into consideration the specific operating conditions, as well as thermophysical properties and parameters of the working fluid. One of the important factors that hinder the wider use of coil heat exchangers is the lack of reliable engineering techniques for calculating the heat transfer and aerodynamic drag.
This study aimed to improve the technique of calculating the heat transfer and aerodynamics of coil heat exchangers by modifying the dependences that take into consideration the specific operating conditions and allow determining the design characteristics of one-layer recuperative coil heat exchangers mounted in annular channels under the conditions of partially twisted working fluid flow. In order to do that, the authors conducted a physical experiment using a test setup, both of which are described in the article in detail.
The analysis of the experimental results on heat transfer in a coil heat exchanger under forced gas convection and laminar flow of the working fluid helped to establish the dependence of the heat transfer coefficient on the main geometric parameters of the heat exchanger and to determine the allowances taking into consideration the extent to which the heat transfer intensity is impacted by the step characteristics of the tube bundle and the gap between the tube bundle and the heat exchanger housing, thus making it possible to optimize the geometric characteristics of the coil heat exchangers mounted in annular channels for specific operating conditions.

Making high quality but affordable Pinot noir (PN) wine is challenging in most terroirs and New Zealand (NZ)’s situation is no exception. To increase the probability of making highly typical PN wines, producers choose to grow grapes in cool climates on lower fertility soils while adopting labour intensive practices. Stringent yield targets and higher input costs necessarily mean that PN wine cost is high, and profitability lower, in affordable varietal wine ranges.To understand if higher-yielding vines produce wines of lower quality we have undertaken an extensive study of PN in NZ. Since 2018, we established a network of twelve trial sites in three NZ regions to find individual vines that produced acceptable commercial yields (above 2.0 kg per metre of row) and wines of composition comparable to “Icon” labels. Approximately 20 % of 660 grape lots (N = 135) were selected within a narrow juice Total Soluble Solids (TSS) range of 22.0 ± 1.0 °Brix and made into single-vine wines under controlled conditions.Multiple Factor Analysis of the vine, berry, juice and wine parameters from three vintages found grape Berry Weight to be the most effective clustering variable. As the Berry Weight category decreased, there was a systematic increase in the probability of higher berry red colour and total phenolics with a parallel increase in wine phenolics and decreased juice amino acids. The influence of berry weight on wine composition would appear stronger than the individual effects of Vintage, Region, Vineyard or vine Yield. Our observations support the hypothesis that it is possible to produce PN wines that fall within an “Icon” benchmark composition range at yields above 2.5 kg per vine, provided that the Leaf Area:Fruit Weight ratio is above 11 cm2 per g, mean berry weight is below 1.2 g and juice TSS is above 22 °Brix.

Published: June 2022

Abstract
BackgroundGood glycaemic control is a crucial part of diabetes management. Traditional assessment methods, including HbA1c checks and self-monitoring of blood glucose, can be unreliable and inaccurate. Continuous glucose monitoring (CGM) offers a non-invasive and more detailed alternative. Availability of this technology is increasing worldwide. However, there is no current comprehensive evidence on the acceptability and feasibility of these devices. This is a protocol for a mixed-methods systematic review of qualitative and quantitative evidence about acceptability and feasibility of CGM in people with diabetes.MethodsWe will search Medline, Embase, CINAHL, CENTRAL for qualitative and quantitative evidence about the feasibility and acceptability of CGM in all populations with diabetes (any type) using search terms for “continuous glucose monitoring” and “diabetes”. We will not apply any study-type filters. Searches will be restricted to studies conducted in humans and those published from 2011 onwards. We will not restrict the search by language. Study selection and data extraction will be carried out by two reviewers independently using Rayyan and Eppi Reviewer, respectively, with disagreements resolved by discussion. Data extraction will include key information about each study, as well as qualitative evidence in the form of participant quotes from primary studies and themes and subthemes based on the authors’ analysis. Quantitative data relating to acceptability and feasibility including data loss, adherence, and quantitative ratings of acceptability will be extracted as means and standard deviations or n/N as appropriate. Qualitative evidence will be analysed using framework analysis informed by the Theoretical Framework of Acceptability. Where possible, quantitative evidence will be combined using random effects meta-analysis, otherwise a narrative synthesis will be performed. The most appropriate method for integrating qualitative and quantitative findings will be selected based on the data available. DiscussionOngoing assessment of the acceptability of interventions has been identified as crucially important to scale-up and implementation. This review will provide new knowledge with the potential to inform a programme theory of CGM as well as future roll-out to potentially vulnerable populations, including those with severe mental illness.

Published: June 2022

Abstract
BackgroundDespite improvement in the overall survival of patients with non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutation, the effects of EGFR tyrosine kinase inhibitor (EGFR-TKI) treatment on bone metastasis remain unclear. This study investigated radiological responses to gefitinib regarding bone metastasis in the patients.MethodsWe treated 260 patients with NSCLC and symptomatic bone metastasis. Thirty-seven patients harboring EGFR mutation were treated with gefitinib for more than 30 days and followed up for more than 3 months (GEF group). We performed a retrospective control study by selecting 36 cases with no EGFR-TKI treatment, at least 3 months of follow-up, and at least two radiological evaluations as the control group. We determined the radiological best overall response, interval from treatment initiation to appearance of a radiological response, and the local response maintenance rate. ResultsThe best effect in the GEF group was 98% partial response or better, which was significantly higher than the 57% observed in the control group (p<0.001). The GEF and control groups maintained 83% and 42% local response maintenance rate at one year, respectively (p<0.001). In the GEF with radiotherapy group, the local response maintenance rate was maintained at 92% at 1 year, while in the GEF without RT group, there was a decrease in the local response maintenance rate from 270 days. ConclusionGefitinib treatment for bone metastases in patients harboring EGFR mutation resulted in beneficial osteosclerotic change in most patients. Combined gefitinib and radiotherapy provides long-lasting local control of bone metastases.

Published: June 2022

Abstract
Purpose
The aim of the present study was to analyse the role of exercises' resistance profile in regional hypertrophy.
Methods
39 healthy women completed a 9-week resistance training program consisting of either 4 sets of 12 repetitions of inclined bicep curls (INC group) or preacher curls (PREA group) three times per week to muscle failure. Pre- and post-intervention muscle thickness was measured using B-mode ultrasound imaging with a linear-array transducer. Scan acquisition sites were determined by measuring the 50%, 60% and 70% of the distance between the posterior crest of acromion and the olecranon.
Results
No region of the INC group grew when comparing pre- to post-intervention. The 70% region of the PREA-group grew (Muscle thickness increased from 2.7 ± 0.43 to 2.94 ± 0.44). We found no growth differences between regions when analysing per group (p = 0.274), region (p = 0.571) or group*region (p = 0.367).
Conclusion
This study shows that regional hypertrophy is affected by the resistance profile of an exercise. Different regions of a muscle will grow in response to exercises that place the highest difficulty in specific points of the range of motion. Our results show that the distal region of the arm grows in response to exercises that place the highest amount of strain in the part of the range of motion in which the arm muscles are more elongated.
Correlation between accuracy in computer guided implantology and peri-implant tissue stability: a prospective clinical and radiological pilot study
Authors: Poli Pier Paolo , Manfredini Mattia , Maiorana Carlo , Beretta Mario 
Published: June 2022

Abstract
Purpose The present pilot study was designed to fill this gap in the literature, hypothesizing a possible correlation between lack of accuracy in implant placement and deterioration of peri-implant hard and soft tissue health. Methods a total of 5 male and female patients were enrolled. Patients underwent computer-guided implant surgery and full arch immediate load between 2013 and 2014. After a follow-up of 5 years, all patients treated with the computer-guided implant placement technique and undergoing evaluation of the accuracy of computer-guided implant placement by postoperative CBCT were recalled for a clinical-radiographic evaluation of peri-implant health status. Accuracy of implant placement was then related to peri-implant hard and soft tissue health variables such as marginal bone resorption, amount of keratinized tissue, recession and plaque and bleeding. Results: Mean linear deviation was 0.57 ± 0.23 mm at implant head and 0.69 ± 0.26 mm at implant apex, while mean angular deviation of the long axis was 2.88° ± 1.22°. A mean MBL of 1.16 ± 0.94 mm and 2.01 ± 1.76 mm was observed after 1 and 5 years of follow-up, respectively. At 5 years, mean PPD was 4.09 ± 1.44 mm, 66.6% of the evaluated implants showed BOP, KM was < 2 mm in 48.4% of cases, REC ≥ 1 mm was assessed in 45.4% of the included implants, plaque accumulation occurred in 66.6% of cases. A negative correlation was observed between bucco-palatal/lingual linear inaccuracy and MBL, PPD, BOP and KM. Conclusions: with the limit of a pilot study, it can be observed that the accuracy of computer-guided implant surgery as described here, obtained satisfactory results. A reduction in accuracy leading to the placement of an implant in an excessively vestibular position may be the cause of peri-implant hard and soft tissue suffering in terms of marginal bone resorption, amount of keratinized mucosa and bleeding on probing.
Optimization of residual stress field and improvement of fatigue properties of thin-walled pipes by filling laser shock peening

Published: June 2022

Abstract
In present work, a kind of filling laser shock peening (LSP) method is put forward and applied to thin-walled pipe. Specimens are experimentally and numerically investigated to identify the residual stress field and fatigue properties of pipe with and without LSP treatment. Numerical simulation indicates that the residual compressive stress increases first and subsequently drops as the laser power density increased, and the extent of influence of the stretching wave reflected from the lower surface on the unloaded area increases with the spot diameter causing surface tensile stress in the unloaded area. By filling the guided wave material within the pipe, the residual stress field of the pipe treated by LSP is optimized, and the influence of the stress wave reflection on the residual stress field is effectively decreased. The surface residual stress of the filled guided wave material is -326MPa, improving by 57.6% as compared with unfilled guided wave materials pipe. The fatigue life of the pipe with filled waveguide material treated by LSP is extended by 48.9% as compared with untreated pipe.
