Published: August 2023

The article deals with the definition and estimation of the parameters of a nonlinear regression model using a genetic algorithm. Parameter estimation is a type of optimization problem that can be solved using stochastic algorithms, which presents the possibility of using such algorithms to fit nonlinear regression models. The trees data set, which displays the non-linear relationship between traits, was investigated. The nonlinear method of least squares (NLS) was used to find the coefficients of the regression equation using a genetic algorithm on the trees data set belonging to the spuRs library. The set contains 1200 observations and three variables: tree ID; age of the tree; volume of wood. Visual analysis revealed the presence of additional signs that affect the volume of wood. Only data for trees with a certain location are selected for further work. As a result, the sample has 12 observations and two variables. The dependence of the volume of wood (Vol) on the age of the tree (Age) was analyzed. Attention to tree locations made it possible to choose the Richards logistic function as a functional dependence, nonlinear both in terms of parameters and variables. A genetic algorithm was used to estimate the parameters of the Richards function. The result of the work of the genetic algorithm depends on how its parameters are configured. When implementing the genetic algorithm, the following parameters were set: population size; the maximum number of iterations after which the work of the genetic algorithm stops; the number of consecutive generations without any improvement in the value of the fitness function before stopping the algorithm. A random scheme was used for the selection operation. A mutation operation involves changing a randomly selected bit. The type of crossover operation is one-point. Coefficients of nonlinear models were calculated for randomly selected tree locations. The coefficient of determination R2 was used to assess the quality of the models.
Improving the interference resistance of multi-color barcode images
Authors: Sulema Yevgeniya , Dychka Andrii
Published: August 2023

A method of improving the interference resistance of multi-color barcodes is pro-posed, which is based on the application of two-level control of errors that occur when scanning a multi-color barcode image, using two multi-valued correcting codes: the BCH code - at the level of barcode patterns (lower level), and the Reed-Solomon code - at barcode symbol level (top level). The proposed method makes it possible to create multi-color barcodes with im-proved immunity characteristics, which ensure reliable reproduction of data during scanning of large-capacity multi-color barcode images in automatic identification sys-tems.

Authors: Poliskyi Yu.D.
Published: August 2023

The purpose of the study. The purpose of the study is an analytical consideration of the system of residual classes for the implementation of the operation of converting numbers from one system of residual classes to another. Method. System analysis, number theory, and the Chinese remainder theorem are tools of the research methodology. The method uses the representation of the number both by its remainders and in the polyadic code. The methodology is based on determining the positional characteristics for this module on the basis of the received positional characteristics for the remaining modules of the original system, with the subsequent construction on their basis of the residuals for the modules of the sought system. The proposed method is algorithmically simple. The results. The theoretical substantiation of the considered approach to obtain an effective solution of the non-modular transformation operation in the system of residual classes for the transition from the representation of a number by one system of modules to its representation by another system of modules is performed.

The information system for the liveness detection process using aws
Authors: Yakovlieva M.A. , Kovylin Ye.R.
Published: August 2023

Analysis of recent studies and publications. The analysis of the modern market of software and algorithmic solutions for performing the Liveness detection process showed that the currently existing approaches are completely commercial solutions with closed algorithms of their work. In addition, the Liveness detection algorithm is not yet standardized, and has many implementation options that can sometimes lead to am-biguous results [7]. That is why, it was decided to develop our own algorithm and liveness detection system based on obtaining face characteristics using the AWS API [8], because this service offers a high accuracy of face recognition, which is 99.99%, and provides 10,000 free requests to use every month, which enough to fulfill the purpose of our work. Purpose of the study. Development of the algorithm for the Liveness Detection process using AWS and the construction of a video identification system based on it. Main research material. This paper investigates the video identification of a per-son using the Liveness Detection process. The basis of the question, complexity of the Liveness Detection process and the implementation of biometric human video identifica-tion have been studied. An algorithm for conducting the Liveness Detection process based on the execution of random tasks by an identified person has been developed. Integration with the Amazon DetectFaces API was carried out in order to obtain the character of a digital image of the head, as a result of which it becomes possible to analyze a photo of a person for a wide range of key facial features. A manual test of the Amazon DetectFaces API was conducted, in the process of which, empirically, thresh-olds of facial characteristics in the image for the Liveness Detection process were set. Integration with the Amazon CompareFaces API was implemented to execute the bio-metric video identification. The testing of the developed Liveness Detection application system based on the created Liveness passing algorithm and selected AWS API thresholds consisted of 100 tests of different orientations, from direct user-flow testing to tests with a medical mask, glasses and beard, a photo of a face and a video image of a person for the purpose of forgery his personality. Thanks to the initial accuracy of Amazon API facial recognition of 99.99% and the random selection of tasks in the developed Liveness Detection algo-rithm, all tests gave the expected result - the person was either successfully video-identified at the enterprise, or his identity was faked during the Liveness Detection pro-cess. Conclusions. Based on the research, the software system of biometric human video identification has been developed, which allows to automatically establish the presence of a person in front of a video camera and identify it, preventing the use of fake artifacts to falsify a person's identity.
Malignant mesothelioma in females: the institutional failure by WHO and IARC to protect public health
Authors: Baur Xaver , Frank Arthur L. , Magnani Corrado , Oliver L. Christine , Soskolne Colin L.
Published: August 2023

Malignant mesothelioma (MM) is a highly aggressive and difficult-to-diagnose tumor that is almost always caused by asbestos or other asbestiform fibers. Chapter 2 in the Fourth (2015) and Fifth (2021) Editions of the WHO/IARC Classification of Tumours is devoted to the classification and pathologic diagnosis of MM. The authors of these Chapters state that most of the cases of MM in females do not show asbestos as the cause when, in fact, the epidemiologic literature shows that the risk of MM in females exposed to asbestos approaches that in males.

While it is correct that the overall incidence of MM in females is lower than in males, the view that MM in females is not caused by asbestos is unsupported. This view results from an inadequate occupational history, the failure to recognize the importance of environmental exposures, and the misrepresentation of published literature by the selection of limited literature and biased bibliographies, often by authors with financial conflicting interests.

In this article, we present an example of the institutional failure (1) to protect the public health by permitting the publication of inaccurate statements about the adverse health effects of exposure to asbestos among females, and (2) to make suggested corrections that more accurately reflect reality.

Responsibility for correcting the misinformation lies, in our assessment, both with the authors of the erroneous statements and with the editors and publisher of the books that contain these statements. At issue is nothing less than scientific accuracy, the fate of at-risk females for whom early diagnosis could result in improved health outcome, a missed opportunity to promote primary and secondary prevention, and the social injustice of the loss of compensation for females so affected. We describe the steps that we took to correct the inaccuracies, and to expose the dereliction of duty among responsible parties based, at least in part, on what we believe to be undisclosed conflicting interests. Our efforts failed.

Basques ethnogenesis, acculturation, and the role of language contacts
Authors: Haarmann Harald
Published: August 2023

In an interdisciplinary approach, processes of ethnic fusion and of language contacts in the Basque country are investigated. Human genetics has confirmed the long continuity of settlement in the Basque country. The Basque people and their language have emerged out of an ethnic fusion in which several pre-Indo-European populations participated, among them groups affiliated to the Caucasian genetic stock. Processes of a long-term acculturation in Basque-speaking communities started in late antiquity when, via the influence of Latin as a language of prestige, the lexical structures of Basque were partly reshaped. Social contacts between Basques and non-Basques were minimal in the Roman era but intensified in post-Roman times. Evidence of this are the foreign elements in Basque kinship terminology which stem from Romance sources.

Broadband focusing of seismic Rayleigh waves by Luneburg lens in the semi-infinite soil
Authors: Tang Zepei , Linghu Zhiang , Yang Hongwu , Peng Pai , Liu Fengming , Du Qiujiao
Published: August 2023

We propose a Luneburg lens for focusing the seismic Rayleigh waves composed of blind holes with varying radii in a semi-infinite soil substrate. Luneburg lenses have a broadband property of achieving a focusing effect from 6 Hz to 9 Hz. It can enhance the wave amplitude by almost 4 times at the focus, and concentrate about 71% of the incident seismic wave energy in the focal area. And its FWHM can reach a minimum of 0.7λ. The effect of wavefront conversion of the Luneburg lens from a cylindrical wave to a plane wave is effectively demonstrated.

Mist CVD was applied to grow the β-Ga2O3 channel layer of a MESFET on a semi-insulating β-Ga2O3 (010) substrate. The mobility and carrier concentration of the channel layer were 80 cm2 V–1 s–1 and 6.2 × 1017 cm−3, respectively. The device exhibited a pinch-off characteristic with a threshold gate voltage of −9 V, and the maximum drain current was 240 mA mm−1. The maximum transconductance was 46 mS mm−1 and the on-resistance was 30 Ω mm. This device performance suggests that mist CVD is a potential growth technology capable of providing low-cost devices in the future.
Homeworking, Care Work and Gender-Based Violence The Condition of Women and Mothers during Covid-19 Domestic Confinement
Authors: Dello Preite Francesca
Published: August 2023

The Covid-19 pandemic, like any social event characterised by the loss of securities and balances, has caused a worsening of the living conditions of women who, suddenly, have experienced the expansion of many problems that already existed before the sanitary emergency, including: job insecurity, the increase in family tasks and loads, and the exacerbation of domestic violence. The contribution, taking into consideration some recent documents and studies published at an international and national level, attempts to analyse these issues and their consequences from a pedagogical and gender perspective, highlighting both the political strategies designed to contrast the forms of discrimination still suffered by women and the crucial role that pedagogy plays in the promotion of educational paths and practices aimed at implementing and consolidating gender equality.
Il profilo dell’insegnante specializzato. Quali variabili nei saperi e nelle prassi di inclusione ed equità?
Authors: Pileri Anna
Published: August 2023

School inclusion in Italy, since its beginnings, opens up the complex issue, not without controversy, of teacher for educational support, defined as specialised if in possession of specific training. It is a profession that, even today, is compromised by representations, opinions, perceptions, and dichotomous postures among curricular and specialised teachers, by cultural resistance and by critical nodes in the co-construction of alliances with families and the territory and among teachers. Aspects that inevitably affect the knowledge and practices of inclusion and equity, the integrated management of the class group and, not secondarily, the involvement of families in their children’s life project. These peculiar elements will be discussed by analysing some of the results of a research-training project involving specialised teachers during their university training and after taking up their posts at school.
Enhancing Engineering Electromagnetics Education: A Comparative Analysis of Synchronous and Asynchronous Learning Environments
Authors: Bilad Muhammad Roil
Published: August 2023

This study evaluates implementation of asynchronous learning in teaching engineering electromagnetics module. A group of first-year engineering students participated in the study. The instruction was divided into two periods, with the first period using asynchronous online mode and the second period using synchronous face-to-face mode. The performance evaluation was based on essay questions on class tests, and the data variances were statistically analysed. In addition, student feedback was gathered through interviews conducted at the end of the semester. In terms of overall performance, the results indicate that synchronous and asynchronous learning methods were equally effective, as no significant difference was found. However, individual student grades revealed a variety of outcomes for the asynchronous learning method, suggesting that students have different learning preferences and levels of adaptability. Positive feedback for asynchronous learning included the ability to adjust the pace of learning and conveniently access course materials. Students valued the availability of recorded lectures for reviewing difficult subject matter. Students with lower study motivation or limited experience with independent learning were negatively affected by the absence of scaffolding and immediate feedback in the asynchronous learning approach. Some students emphasized the importance of face-to-face interaction with the instructor, especially in a subject like electromagnetics that requires intuitive thought and elaboration.

Authors: Saha Prabir Kumar , Begum Ferdousy
Published: August 2023

Introduction: Lymphoma, a type of cancer affecting the lymphatic system, requires accurate diagnostic methods for effective treatment. This study aimed to evaluate the validity of Cell Block Histopathology and Fine Needle Aspiration Cytology (FNAC) in the diagnosis of lymphoma. Methods: A total of 30 patients with clinically suspected lymphoproliferative disorder were included in the study. Both Cell Block Histopathology and FNAC were used to diagnose lymphoma in these patients. The results were then compared with the final diagnosis based on histopathology, immunochemistry, and clinical follow-up, which was considered the gold standard. Result: The study included 30 patients with clinically suspected lymphoproliferative disorder. The Cell Block Histopathology method diagnosed 12 patients (40%) as lymphoma positive, 11 patients (36.67%) as lymphoma negative, and 7 cases (23.33%) were inconclusive. The Fine Needle Aspiration Cytology (FNAC) method diagnosed 13 patients (43.33%) as lymphoma positive, 12 patients (40%) as lymphoma negative, and 5 cases (16.67%) were inconclusive.When compared with the final diagnosis based on histopathology, immunochemistry, and clinical follow-up, the sensitivity, specificity, and accuracy of Cell Block Histopathology were 91.67%, 90.91%, and 93.33% respectively. The positive predictive value (PPV) and negative predictive value (NPV) were both 91.67%. The FNAC method demonstrated a sensitivity, specificity, and accuracy of 92.31%, 91.67%, and 93.33% respectively. The PPV and NPV were 92.31% and 91.67% respectively. Conclusion: This study concludes that both Cell Block Histopathology and FNAC are valid and effective diagnostic tools for lymphoma. They can be used independently or in conjunction with one another to enhance diagnostic accuracy. The findings contribute to the growing body of evidence supporting the use of these methods in lymphoma diagnosis.

Acute appendicitis is the most frequent abdominal surgical emergency in the world. The aim of this study was to analyse the results of surgical management of acute appendicitis. Methodology: This was a prospective study from January 2020 to December 2020 in the reference health centre in Commune I of Bamako. Results: During this period, we operated on 108 patients for acute appendicitis, including 78 men and 30 women, for a sex ratio of 2.5. The mean age was 26.92 years, ranging from 5 to 70 years. Abdominal pain was the main reason for consultation. Physical signs were dominated by a positive Blumberg's sign in 99.1% of cases, right iliac fossa defensiveness in 97.2% of cases, Rovsing's sign in 50% of cases, psoitus (Psoitis) in 18.5% and pain on the right in the cul de sac of Douglas in 69.4%. This physical examination enabled the diagnosis to be made in the majority of cases. In some doubtful cases, we requested an abdominal ultrasound scan. Locoregional anaesthesia was the most commonly used anaesthetic technique (63.9%). Classic Mac Burney appendectomy with burial of the stump was the surgical technique most frequently used. Postoperative recovery was straightforward in 97.2% of cases. However, we recorded one case of death. Conclusion: Acute appendicitis remains the most frequent abdominal surgical emergency in the community. Early diagnosis and rapid management improve prognosis. Treatment is essentially surgical.
Fixed Prosthesis on Two Implants from Different Manufacturing Companies Case Report
Authors: González Jesús M. González-
Published: August 2023

The following is a clinical case of a screw-retained prosthesis on two implants with different designs and manufacturers. A 73-year-old man visited the dentist in January 2023 to rehabilitate the edentulous right area of the mandible. In December 2018 another dentist placed implants (Biohorizons, Madrid. Spain) in positions 45 and 46 with a metal-porcelain bridge over both. In 2022 he lost implant 45 (Biohorizons tapered internal 3.8 x 9) and with it also the bridge, although he still had implant 46 (Biohorizons tapered short 4.6 x 7.5). On the day of surgery, a simple opening flap was performed and drills were used sequentially until a 4 x 8 mm Galimplant IPX implant (Sarria, Spain) was placed in position 45. After a period of four months, the impression abutments of implants 46 and 45 were attached with dental floss and flowable composite, and an open-tray impression was taken. One week later, the screwed metal-porcelain fixed prosthesis was placed on both implants. It is difficult to find bibliographic information about fixed prostheses on implants manufactured by different companies and placed in the same patient. The placement of a prosthesis on two implants from different manufacturers is not a complication, but rather an unscheduled inconvenience. The clinical case presented allows us to point out that a fixed prosthesis on implants from different manufacturers can give excellent results.
Crime Analysis of Payment Transactions Using Checks and Giro Bilyets
Authors: Paturochman Iwan Ridwan
Published: August 2023

Background: The growing level of crimes committed by unscrupulous businessmen related to payments using blank checks or giro drafts makes it important to conduct research whether this includes criminal law in the realm of criminal law or only civil law. Object: The object of this research is a payment crime involving the use of blank checks and demand deposits in a banking environment. The purpose of this analysis is to ascertain whether this is a crime that belongs to the realm of crime or not. Method: The research method used is literature study and relevant data analysis. In this analysis, data were collected on payment crime cases using blank checks and demand deposits, as well as interviews. The data includes statistics, case studies, and reports from law enforcement and related financial institutions. Result: The results of the analysis show that payment traffic using blank checks and giro forms is a form of criminal offense in accordance with articles 378 and 379a of the Criminal Code in Indonesia. Payments using blank checks and demand deposits have a significant impact on banking and society. This crime is detrimental to the parties who become victims, such as traders, entrepreneurs, and individuals who receive payments with these financial instruments. Several factors that influence payment crimes include technological developments, lack of public awareness, ineffective banking supervision systems, and the increased ability of criminals to manipulate financial instruments. In an effort to deal with payment crimes using blank checks and demand deposits, effective preventive measures and law enforcement are needed. These efforts include increasing public awareness of the risks and signs of this crime, increasing the security of financial instruments, cooperation between banks and law enforcement agencies, and using more sophisticated security technology.

Published: August 2023

Background: Prior vaccination can prevent a COVID-19 patient from falling into moderate, severe, and critical conditions. The effect of vaccination on COVID-19 patients’ recovery has been widely studied. However, its correlation in critically severe COVID-19 patients with comorbidity has not been fully understood yet. This study aims to determine the correlation of vaccination in critically severe COVID-19 patients with comorbidity of hypertension and/or Diabetes Mellitus (DM).Methods: A retrospective cohort study was conducted in critically severe COVID-19 patients with hypertension and/or DM treated in Dr. Moewardi Hospital, Surakarta, Indonesia from March 2021 to September 2021. The data were taken from patients’ medical records. We analyzed all data statistically with Chi-Square and fisher's exact test, and a p-value of < 0.05 was considered significant.Results: There were 489 patients included in our study, 247 patients with hypertension and DM, and 242 patients without comorbidities. Vaccination status was significantly associated with the cure rate of critically severe COVID- 19 patients with hypertension (p=0.018), but not with DM (p=0.606). There was no significant association between age to the cure rate of critically severe COVID-19 patients with hypertension and DM (p=0.953). Vaccination status was related among patients with comorbidities and without comorbidities (p<0.001).Conclusion: Vaccination was significantly correlated the cure rate of moderate to critically severe COVID-19 patients with hypertension and without comorbidities.
Association of the Vaccination Status of Health Workers of COVID-19 Survivors with The Outcomes of Treatment of COVID-19 At General Hospital in Padang City
Authors: Aribowo Kornelis , Basyar Masrul , Sabri Yessy Susanty
Published: August 2023

Background: Health workers are on the front lines of treating and fighting the COVID-19 pandemic. Health workers face COVID-19 patients at work. Health workers are at increased risk of infection if they are not properly protected. Increased risk for health workers can be caused by contact with patients without personal protective equipment (PPE) and surfaces contaminated with the virus. Infected health workers can infect other people around them and will increase the workload of other health workers. One of the efforts to reduce the risk of transmission to health workers is vaccination. Vaccines against COVID-19 are considered very important to prevent and control COVID-19. The aim is to determine the relationship between the COVID-19 vaccine status and the outcomes of healthcare workers treated for confirmed COVID-19 at hospitals throughout Padang.Methods: This observational study was conducted using a retrospective cohort method. The study was conducted from August 2021 to May 2022 in hospitals across Padang by completing a questionnaire in the form of a Google form link. Results: Vaccination status of health workers who survived COVID-19 who were treated at Padang City General Hospital (66.97%) were not vaccinated, aged 26–35 years (57.80%), female (80.73%), worked as paramedics (63, 55%), symptom onset 3 to 7 days (44.95%), number of symptoms 3 (55.96%), most fever (24.68%), number of comorbid 1 to 2 (66.06%), obesity (66.67%), length of stay <21 days (84.40%), and mild clinical (55.96%) and recovered (92.66%). The highest degree of COVID-19 severity for health workers who were not vaccinated was moderate clinical, 42 samples (57.53%), and vaccinated, predominantly mild clinical, 34 samples (94.44%). The duration of stay of health workers vaccinated was higher than that who were not vaccinated (97.22% vs. 78.08%).Conclusion: The vaccination status of health workers who have survived COVID-19 relates to a clinical degree, length of stay, and outpatient treatment.

This study's objective is to assess the level of customer satisfaction and product quality in the consultation and project office of Ethiopian Leather Industry Development Institute. Importance of customer satisfaction cannot be undermined for any organisation. The processes and practices of Corporate governance should assess the service gaps and should aim to fulfil the same. The SERVQUAL instrument is used in conjunction with the gap model of service quality to carry out this research. the five SERVQUAL dimensions of tangibles, reliability, responsiveness, assurance, and empathy were used to gauge the extent of customers' expectations and perceptions of service quality. A sample of 240 respondents was selected using a non-probabilistic convenience sampling technique. According to the findings of the study all the five dimensions of service quality have shown a negative gap score. This indicates that customers of Ethiopian leather industry development institute consultancy and project office are dissatisfied with the service provided to them hence; there perceptions are below their expectations. The dimension with the lowest negative gap score is assurance followed by tangibles and responsiveness. The findings of the gap analysis also indicate that tangibility and responsiveness are the two dimensions with the highest negative gap scores which makes these two dimensions the largest contributors to customer’s dissatisfaction. Pearson correlation analysis was conducted to examine the relationship between SERVQUAL dimensions and service quality the results shows that all the five dimensions of service quality have a positive relationship with customer satisfaction where tangibility, empathy and responsiveness have a moderate and positive correlation with satisfaction while assurance and reliability have a weak positive correlation with customer satisfaction. Generally, only tangibility and responsiveness dimensions of service quality have shown statistically significant impact on customer satisfaction. Accordingly, Ethiopian leather industry development institute consultancy and project office needs to give more emphasis and due attention to tangibility and responsiveness dimensions of service quality to improve the level of customer satisfaction.

Beside of environmental conditions, ship characteristics also greatly affect in ship behavior when operating at sea, called seakeeping ability. The shape of the hull, appendages, damping, and the weight distribution of ship are some of the factors that determine how the ship motion response occurred. This paper examines how much the pitch motion is influenced in high-speed craft due to the changing of the gyration radius. By using the strip theory method, and by taking the irregular head sea condition and a wave height of 4 meters, then the ship speed and the wave period are varied to determine the pitch motion amplitude at 3 values ​​of gyration radius: 0.2, 0.25 and 0.3 of the ship's length. The results of the study show that at higher ship speeds, the gyration radii greatly influence the pitch amplitude. As for changes in the wave period, the influence is significant at value of 5 second. From these two results, it is clear that the ship's gyration radii must be determined precisely to be able to predict an accurate pitch motion response on a high-speed craft.

Coal mines are generally located in very remote areas and so far from the reach of the power grid. This study designs a coal waste measurement device using solar energy as the power source. The parameter being measured for coal waste is its acidity level to determine water quality standards. The test results show that the photovoltaic (PV) system is capable of supplying power to the pH meter device for a duration of 24 hours with a battery capacity of 18 Ah. The total load of this system is 5.6983 Watts. With variations in load and different weather conditions such as clear, cloudy, and overcast, the solar panel voltage can effectively meet the load requirements within the voltage range of 16.7 volts to 20.9 volts.

Solar energy is extraordinary and the largest energy on earth and no pollution. Solar cell technology is a technology that can absorb solar energy and convert in to electrical energy. In general, the installation of solar panels is only in one direction so that the absorption by the photovoltaic collector will not be optimal. Subsequence, the electricity produced is also less than optimal. To optimize the absorption of sunlight, the photovoltaic collector must be parallel to the sun. In this study, 4 LDR light sensors were used as detectors of the highest intensity of sunlight, the LDR output would enter the Arduino Mega microprocessor and control the DC motor to drive the solar panels. The monitoring process used a current/voltage sensor (INA219), temperature and humidity sensor (DHT 11), data from the sensor was processed by the ESP8266 Node MCU and then the data can be accessed via an Android Smartphone using the Blynk application. These data were transmitted to users wirelessly via the ESP8266 Node MCU module. From the test results, the energy generated when the solar cell was stationary averages V = 14.28 volts, I = 0.66 A and the energy when the solar cell moved averages V = 14.63 volts, I = 0.92 A. Therefore, the comparison of electric power in the condition that the solar panels moved according to the movement of the sun has increased by 30.13% compared to the stationary condition.

A Further Extension of Rödl's Theorem
Authors: Nguyen Tung
Published: August 2023

Fix $\varepsilon>0$ and a nonnull graph $H$. A well-known theorem of Rödl from the 80s says that every graph $G$ with no induced copy of $H$ contains a linear-sized $\varepsilon$-restricted set $S\subseteq V(G)$, which means $S$ induces a subgraph with maximum degree at most $\varepsilon |S|$ in $G$ or its complement. There are two extensions of this result:

quantitatively, Nikiforov (and later Fox and Sudakov) relaxed the condition "no induced copy of $H$" into "at most $\kappa|G|^{|H|}$ induced copies of $H$ for some $\kappa>0$" depending on $H$ and $\varepsilon$; and

qualitatively, Chudnovsky, Scott, Seymour, and Spirkl recently showed that there exists $N>0$ depending on $H$ and $\varepsilon$ such that $G$ is $(N,\varepsilon)$-restricted, which means $V(G)$ has a partition into at most $N$ subsets that are $\varepsilon$-restricted.

A natural common generalization of these two asserts that every graph $G$ with at most $\kappa|G|^{|H|}$ induced copies of $H$ is $(N,\varepsilon)$-restricted for some $\kappa,N>0$. This is unfortunately false, but we prove that for every $\varepsilon>0$, $\kappa$ and $N$ still exist so that for every $d\ge0$, every graph with at most $\kappa d^{\vert H\vert}$ induced copies of $H$ has an $(N,\varepsilon)$-restricted induced subgraph on at least $\vert G\vert-d$ vertices. This unifies the two aforementioned theorems, and is optimal up to$\kappa$ and $N$ for every value of $d$.
Probabilistic Parking Functions

Published: August 2023

We consider the notion of classical parking functions by introducing randomness and a new parking protocol, as inspired by the work presented in the paper ``Parking Functions: Choose your own adventure,'' (arXiv:2001.04817) by Carlson, Christensen, Harris, Jones, and Rodríguez. Among our results, we prove that the probability of obtaining a parking function, from a length $n$ preference vector, is independent of the probabilistic parameter $p$. We also explore the properties of a preference vector given that it is a parking function and discuss the effect of the probabilistic parameter $p$. Of special interest is when $p=1/2$, where we demonstrate a sharp transition in some parking statistics. We also present several interesting combinatorial consequences of the parking protocol. In particular, we provide a combinatorial interpretation for the array described in OEIS A220884 as the expected number of preference sequences with a particular property related to occupied parking spots. Lastly, we connect our results to other weighted phenomena in combinatorics and provide further directions for research.
