Framework based on conformal predictors and power martingales for detection of fixed football matches
Authors: Zhuk Ivan , Chertov Oleg 
Published: May 2023

One of the difficult problems that arises during football competitions is match-fixing. In terms of negative effect, such shameful phenomena are commensurate with the problem of doping. This paper has analyzed known methods for the possible detection of match-fixing, including sociological analysis of participants in match-fixing, methods for predicting the outcome of the match, analysis of bets and performance of the player or team during the match. It is noted that the assessment of match-fixed results in the considered methods is carried out based on the analysis of a large amount of data. But such information is not always available. Given the insufficient formalization of the problem area, it is relevant to conduct research that does not require a large amount of non-publicly available data but, at the same time, makes it possible to effectively identify potentially suspicious matches regarding a fixed result. The description of the input data is formalized in the form of a data structure containing a chronological history of the results of football seasons, the ranking of teams and matches of the season depending on the overall result of the teams in the season. A method for detecting suspicious football matches with a fixed result has been built using conformal predictors and power martingales within which a new measure of non-conformity has been introduced to determine atypical football matches. To obtain a generalization of the statistics of atypical matches, a power submartingale was used. Evaluation of the effectiveness of the developed method for detecting suspicious football matches was carried out based on precision and recall of the classification metrics using data on the 2013–2014 season of the French II League. The quality of work of the developed method reaches 85 % in terms of precision metric, 96 % in terms of recall metric, and 0.853 in terms of metric F1.

To provide the quality of the surface layer and improve operational properties, a combined laser-ultrasonic surface hardening and finishing technology of steel products is proposed. This work is devoted to determining the range of rational parameters of laser heat treatment and ultrasonic impact treatment for enhancing the complex hardening process of AISI 1045 steel and AISI D2 steel. Laser surface transformation hardening was carried out with a constant temperature strategy using a fiber laser and scanning optics at a heating temperature of 1200–1,300 °C and a processing speed of 40–140 mm/min. Ultrasonic surface hardening and finishing were performed on technological equipment with an amplitude of ultrasonic vibration of 18 μm and a load of the ultrasonic tool of 50 N. The ultrasonic treatment duration varied from 60 to 180 s. The results showed that laser-ultrasonic treatment leads to an increase in the hardening intensity by more than 200 %, forming a hardening depth of 200–440 μm. Combined treatment leads to a significant increase in wear resistance due to the formation of ultrafine-grained martensitic microstructure with hardness (58–60 HRC5) in the near-surface layer. The combined laser-ultrasonic hardening process control algorithm for surface treatment of structural and tool steels is proposed, limiting the heating temperature, the duration of laser (ultrasonic) exposure, and the vibration amplitudes of the ultrasonic horn. Laser-ultrasonic treatment will allow the formation of a surface layer with a given set of properties, providing increased wear and corrosion resistance. The developed technology can be used for surface hardening and finishing of large-sized steel products in the mechanical engineering industry.

The aim. The study aimed to determine the prevalence of tobacco smoking among pharmacy workers in Ukraine, their awareness of the harmfulness of certain types of cigarettes, the attitude of pharmacy managers and pharmacists towards their colleagues’ smoking, as well as the ability of pharmacists to provide effective help in smoking cessation and assessment of prospects for the participation of pharmacists in tobacco smoking control programs if such programs are to be implemented in Ukraine.
Materials and methods. The survey involved 239 employees of Ukrainian pharmacies under the age of 30 working in different regions. According to the geographical structure, the respondents represent 22 regions of Ukraine.
Results. The experience of countries where active assistance to those who want to quit smoking pharmacists are involved suggests that pharmacists' support can help increase adherence to smoking cessation drugs and provide additional behavioural support as an adjunct to pharmacotherapy, which is quite effective. Currently, there are no such programs in Ukraine.
The survey results show that Ukrainian pharmacists under the age of 30 are aware of the dangers of smoking. Most of them assess the level of their training in smoking cessation assistance as sufficient, but they only mean advice on the use of drugs in smoking cessation.
Conclusions. Thus, in order to introduce the services of active support by pharmacists for people trying to quit smoking in Ukraine, it is required to create the necessary conditions for the interest of pharmacies and pharmacists in carrying out this type of activity and the implementation of programs of additional training in methods of active support for people trying to quit smoking

Published: May 2023

We consider special topological vector spaces with a commutative multiplication for some of elements of the spaces and monogenic functions taking values in these spaces.Monogenic functions are understood as continuous and differentiable in the sense of G\^ateaux functions.We describe relations between the mentioned monogenic functions and harmonic vectors in the three-dimensional real space and establish sufficient conditions for infinite monogeneity of functions. Unlike the classical complex analysis, it is done in the case where the validity of the Cauchy integral formula for monogenic functions remains an open problem.

Published: May 2023

BackgroundA pilot newborn hearing screening (NHS) program was established at 11 Corporation Maternity Hospitals in Chennai, a city in South India, to aid in the early detection of hearing loss. Nurses were trained how to screen newborns using both otoacoustic emissions (OAEs) and automated auditory brainstem responses (AABRs). The purpose of this qualitative study was to explore nurses’ perceptions of the NHS program and the challenges they faced in implementing it.Material and methodsSemi-structured interviews were conducted with 11 nurses, one from each hospital, who performed NHS in Corporation Maternity Hospitals. Interviews were conducted using guides and probes developed and validated by experts.ResultsFour general themes that covered the nurses’ responses were identified: their understanding of NHS and skills in its execution; gaps in their understanding of the NHS program, constraints faced in implementing the screening program, and additional needs for support.ConclusionsAddressing gaps in training needs, providing full documentation, and overcoming poor adherence to NHS protocols would help the program grow. The lessons learnt are also transferable to programs conducted in similar low–middle income countries.

Catfish is health food which contains good nutritional values. Aceh people frequently consume this fish in fresh with complicated special recipe, so that the rate consumption of this fish is still low. Therefore, it is important to find the method for preserving this fish to improve its consumption. Liquid smoke can be used as one method to prepare the fish. The purpose of this study is to assess the quality of catfish under the treatments with and without soaking the fish in liquid smoke.Catfish was cleaned and washed, then it was dipped in solution with 2% salt for 30 min. Afterthat, catfish were air-dried for about 1 hour. About 200 ml of liquid smoke was diluted in 9800 ml water. After soaking in solution with 2% liquid smoke for 10min, catfish were dried by using a cabinet dryer which has three layers. The parameters observed were moisture content and sensory analysis. About 25 panelists had evaluated the samples for appearance, flavor, taste, texture, and color.The results showed that the combination process of smoking and drying might maintain the product quality. The moisture contents of all products were still in appropriate amount as required by the Indonesian Standar (SNI). According to organoleptic test, the smoke-dried catfish was preferred by panelist than the unsmoked-dried one. Therefore, soaking catfish in liquid smoke can be used to improve the taste of the fish. Further study is recommended to evaluate the shelf life of smoke-dried catfish.

Wine made or stored in clayware ceramic pots attracts the attention of consumers, but this practice is less studied than when classic stainless steel tanks or wood barrels are used. It is known that wine can be influenced by the container in which it is aged. To analyse the influence of ceramics on the chemical composition of wine, Armenian clay-based ceramic tablets were immersed in model wine and aged from 1 hour up to 16 months at 25 °C in darkness. The concentrations of 26 elements (namely: Al, B, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sr, Ti, V, W and Zn) in 19 samples were determined by ICP-AES analysis. Proton time domain NMR relaxometry was used to characterise the iron redox processes that occurred in the model wine in contact with a ceramic. A fast increase in the pH of the model wine in contact with the bare ceramic tablet (from 2.35 to 5) was recorded in 4 days. The coating of the ceramic tablets with beeswax showed a significant effect on the interaction between the model wine and the ceramic.
Cosmic Dancers, Cosmetic Shells: Exploring the Queer Potential of London’s Blitz in the Early Thatcher Era
Authors: Edwards Chloë 
Published: May 2023

This paper concentrates on the ways in which masculinity and male (homo)sexuality were challenged, depicted, and expressed within the New Romantic subculture of Margaret Thatcher’s first term (1979-1983). Centring on the subculture’s nucleus, the Blitz nightclub in London’s Covent Garden, which served as a safe space in which its clientele could explore their identities away from the prevailing Conservative ideology of the time, I examine the work of prominent figures who prompted reflections on attitudes towards mainstream gay visibility and the shift in representations of queerness within popular culture in Thatcher’s Britain. Considering the legacy of punk’s contradictory attitudes towards non-heterosexual identities and its ‘do-it-yourself’ ethos with questions of class, this paper questions the intersections of and tensions between identity and consumption under Thatcher. Tracking the rise of the young, arts-oriented demographic of the Blitz and those who facilitated the subculture’s move from outside, to inside of the mainstream popular music scene, namely Steve Strange of Visage and Boy George, I offer a queer reading of their output that illustrates the subversive subculture’s ability to bring non-heterosexual masculinities into mainstream popular music in early 1980s Britain, concurrently demonstrating that assessments of the subculture as being only aesthetically-oriented are too reductive.

Published: May 2023

Background:
Robotic-arm-assisted unicompartmental knee arthroplasty (UKA) has been shown to result in high short- and mid-term survivorship. However, it is not known whether these outcomes are maintained at long-term follow-up. This study aimed to evaluate long-term implant survivorship, modes of failure, and patient satisfaction following robotic-arm-assisted medial UKA.

Methods:
A prospective multicenter study of 474 consecutive patients (531 knees) undergoing robotic-arm-assisted medial UKA was conducted. A cemented, fixed-bearing system with a metal-backed onlay tibial implant was used in all cases. Patients were contacted at 10-year follow-up to determine implant survivorship and satisfaction. Survival was analyzed using Kaplan-Meier models.

Results:
Data were analyzed for 366 patients (411 knees) with a mean follow-up of 10.2 ± 0.4 years. A total of 29 revisions were reported, corresponding to a 10-year survivorship of 91.7% (95% confidence interval, 88.8% to 94.6%). Of all revisions, 26 UKAs were revised to total knee arthroplasty. Unexplained pain and aseptic loosening were the most commonly reported modes of failure, accounting for 38% and 35% of revisions, respectively. Of patients without revision, 91% were either satisfied or very satisfied with their overall knee function.

Conclusions:
This prospective multicenter study found high 10-year survivorship and patient satisfaction following robotic-arm-assisted medial UKA. Pain and fixation failure remained common causes for revision following cemented fixed-bearing medial UKA, despite the use of a robotic-arm-assisted technique. Prospective comparative studies are needed to assess the clinical value of robotic assistance over conventional techniques in UKA.

Resampled dimensional reduction for feature representation in machine learning
Authors: Sufriyana Herdiantri , Wu Yu Wei , Su Emily Chia-Yu 
Published: May 2023

Abstract
We aimed to provide a resampling protocol for dimensional reduction resulting a few latent variables. The applicability focuses on but not limited for developing a machine learning prediction model in order to improve the number of sample size in relative to the number of candidate predictors. By this feature representation technique, one can improve generalization by preventing latent variables to overfit data used to conduct the dimensional reduction. However, this technique may warrant more computational capacity and time to conduct the procedure. The key stages consisted of derivation of latent variables from multiple resampling subsets, parameter estimation of latent variables in population, and selection of latent variables transformed by the estimated parameters.
