In modern data warehousing, data skipping is essential for high query performance. While index structures such as B-trees or hash tables allow for precise pruning, their large storage requirements make them impractical for indexing secondary columns. Therefore, many systems rely on approximate indexes such as min/max sketches (ZoneMaps) or Bloom filters for cost-effective data pruning. For example, Google PowerDrill skips more than 90% of data on average using such indexes.
In this paper, we introduce Cuckoo Index (CI), an approximate secondary index structure that represents the many-to-many relationship between keys and data partitions in a highly space-efficient way. At its core, CI associates variable-sized fingerprints in a Cuckoo filter with compressed bitmaps indicating qualifying partitions. With our approach, we target equality predicates in a read-only (immutable) setting and optimize for space efficiency under the premise of practical build and lookup performance.
In contrast to per-partition (Bloom) filters, CI produces correct results for lookups with keys that occur in the data. CI allows to control the ratio of false positive partitions for lookups with non-occurring keys. Our experiments with real-world and synthetic data show that CI consumes significantly less space than per-partition filters for the same pruning power for low-to-medium cardinality columns. For high cardinality columns, CI is on par with its baselines.

Published: October 2020

Abstract
The effect of different nanomaterials on the aging resistance of asphalt was investigated. Three types of nanomaterials, organic expanded vermiculite (OEVMT), nano zinc oxide (ZnO), and multi-dimensional nanomaterials composed by OEVMT and ZnO, were compared. The results show that the single nanomaterial (OEVMT or ZnO) can only enhance one of the abilities to resist thermal-oxidative aging and ultraviolet aging, whereas the multi-dimensional nanomaterials can improve both types of aging resistance effectively. Moreover, compared with the single nanomaterials, the multi-dimensional nanomaterials under the same content show an excellent synergetic effect on thermal-oxidative antiaging ability and have the equivalent ultraviolet aging resistance.

Population Based Birth Prevalence of Disease-Specific Perinatal Stroke
Authors: Dunbar Mary , Mineyko Aleksandra , Hill Michael , Hodge Jacquie , Floer Amalia , Kirton Adam 
Published: October 2020

BACKGROUND:Perinatal stroke encompasses multiple disease-specific cerebrovascular syndromes that cause lifelong neurodevelopmental morbidity for millions worldwide. Acute presentations include neonatal arterial ischemic stroke (NAIS), neonatal cerebral sinovenous thrombosis, and neonatal hemorrhagic stroke (NHS). Delayed presentations include arterial presumed perinatal ischemic stroke, periventricular venous infarction, and presumed perinatal hemorrhagic stroke. Our objective was to define the birth prevalence of all subtypes of perinatal stroke by using a population-based cohort.METHODS:The Alberta Perinatal Stroke Project is a research cohort established in 2008 in southern Alberta, Canada, with prospective (2008–2017) and retrospective (1990–2008) enrollment leveraging universal health care at a single tertiary care pediatric center. The primary outcome was the estimated birth prevalence of each perinatal stroke syndrome, secondary outcomes were birth prevalence over time, sex ratios, and change in age at diagnosis. Analysis included Poisson regression, Wilcoxon rank test, and Fisher exact test.RESULTS:The overall estimated birth prevalence of term-born perinatal stroke was 1:1100. The estimated birth prevalence was 1:3000 for NAIS, 1:7900 for arterial presumed perinatal ischemic stroke, 1:6000 for periventricular venous infarction, 1:9100 for cerebral sinovenous thrombosis, 1:6800 for NHS, and 1:65000 for presumed perinatal hemorrhagic stroke. The apparent birth prevalence of NAIS and NHS increased over time. There were more males affected than females. The age at diagnosis decreased for late-presenting stroke types.CONCLUSIONS:The estimated birth prevalence of term perinatal stroke is higher than previous estimates, which may be explained by population-based sampling of disease-specific states. This emphasizes the need for further studies to better understand the disease-specific pathophysiology to improve treatment and prevention strategies.
The Rhythms of NEP
Authors: Ginzburg Lyubov 
Published: October 2020

The article revisits the story behind Dmitri Shostakovich's orchestration of a popular tune, "Tea for Two," by Vincent Youmans in 1924. The episode is discussed within a broader context of the NEP era and its infatuation with the innovative American art form known as jazz. Steeped with an array of newly revealed circumstances, it is bestowed with unexpected new meanings and symbols that reverberate in such disciplines as comparative cultural studies, international affairs, and Russian-American relations.
The Triumph and Anguish of the Russian Revolution: Bessie Beatty's Forgotten Chronicle
Authors: Ginzburg Lyubov 
Published: October 2020

The article gives a long-overdue consideration to a gendered narrative that until recently has been among discourses often excluded from historical scrutiny in the process of understanding and interpreting the Russian Revolutions of 1917. It is dedicated to American journalist Bessie Beatty, one of a dozen foreign correspondents who arrived in Russia to report on the history unfolding in the crumbling empire. The piece is a homage to Beatty's legacy of an ardent suffragist and devoted pacifist, whose life was effervescent with places, individuals, adventures, and events that would reverberate throughout the 20th century and beyond. Whether covering miners' unrest in Nevada, castigating the system for profiting from prostitutes' deplorable plight in San Francisco, or trying to decipher the convoluted social turmoil in revolutionary Petrograd, she would always manifest compassion and humanism, revealing the lives of individuals, rather than drawing an impersonal and generalized picture of the masses. Most importantly, the author strives to prevent Beatty's work from oblivion and amplify her opposition to war, the heavy toll of which she first witnessed reporting from the Russian front a century ago, when she exposed pervasive human suffering, denounced the lust for blood, and lamented the total deprivation of human dignity. While it may not bring to naught an ever-growing anguish in the face of current precarious rivalries and never-ending gnawing strife, it may help to revive Beatty's hope that "the muddled old world" would be once remade "upon a basis of human freedom and safety".

Published: October 2020

Introduction. The study of financial behaviour and human activity in relation to the management of material resources seems relevant both from the point of view of identifying potential risks of deviant behaviour patterns in this area, and identifying training opportunities for effective management of their own financial resources. The studies of financial behaviour of young people in conjunction with parent-child relationships are poorly presented in modern science and are conducted mainly abroad. Due to the lack of data, the value of the Russian research is great due to the high demand for scientific ideas about such relationship.The aimof the present research is to identify the interdependence between child-parent relationships and the financial activity of young people through the correlation of their models of financial behaviour, as well as the search for determinants of the activity of boys and girls in the system of parenting.Methodology and research methods. An empirical study was conducted on two related samples – youth representatives (young teenagers aged from 14 to 16 years old) and their parents. The total number of study participants was 144 people, of which 87 parents (57 women and 30 men) and 57 youth representatives (29 girls and 28 boys). For data collection, the authors compiled a questionnaire. This questionnaire contains two blocks: an assessment of the financial activity of the family and an assessment of the financial activity of youth. Also, the authors employed the methodology “Family Relationship Analysis” (by E. G Eidemiller, V. V. Yustitskis) and the questionnaire “Parent Behaviour and the Attitude of Children toward It” (by E. Schafer). Processing of the obtained data was carried out in the statistical package IBM SPSS Statistic 19.0. For mathematical and statistical analysis, the methods of descriptive statistics, cluster analysis, correlation analysis and regression analysis were used.Results and scientific novelty. As a result of an empirical study, two statistically significant regression models were constructed. According to the obtained models, some features of parent-child relationships really stimulate the financial activity and independence of youth. The groups of financially active and passive boys and girls are identified. It is established that these groups differ only in relation to their own assessments of parental impact by the mother.Practical significanceof the work lies in the possibility of using the obtained data to form a scientific understanding of the genesis and mechanisms of formation of a person’s financial activity, as well as in identifying target groups and developing effective methods for teaching financial literacy of the population.
IT education as a factor to influence gender imbalances in computing: Comparing Russian and American experience.
Authors: Khenner E. K. , Frieze C. , Zane O. 
Published: October 2020

Introduction. The problem of the relatively small number of women professionally employed in computing (computer science and information technology) is relevant throughout the world. Despite the fact that IT professionals are widely in demand, women in many countries, including theUSA andRussia, make up no more than a quarter of their total number, which requires explanation. One of the major reasons for this phenomenon, according to the authors, lies in the education system.The aim of this article was to analyse the factors affecting gender imbalance in IT professions, by comparing two countries in which information technology has historically played an important role, and which are very different from each other in many ways – economic, political, educational system and others.Research methodology. The present research is based on the comparison of data on IT education in schools and universities, and the degree of involvement of girls and women in computing in theUSA andRussia.Results. Both in theUSA and inRussia, gender imbalances in IT professions are formed largely in the field of education. Cultural stereotypes about computing as a male-dominated profession are produced by the media. Such stereotypes can discourage some girls and young women from studying computer science and also result in imbalance formation. The education system needs to increase the confidence of girls and young women in the possibilities of realising their abilities in the field of computer science and information technologies. Educational institutions should help to eliminate the negative attitude towards girls’ choice of IT professions.Scientific novelty. For the first time, general factors in the field of education were identified that affect gender imbalances among IT professionals inRussia and theUSA – the countries with significantly different traditions and educational systems.Practical significance of the present work is to justify the conditions for improving school and university education to solve the problem of gender inequality in IT industry.

Published: October 2020

AbstractParnassius (Lepidoptera: Papilionidae) is a genus of attractive butterflies mainly distributed in the mountainous areas of Central Asia, the Himalayas, and western China. In this study, we used the internal transcribed spacer (ITS1 and ITS2) sequence data as DNA barcodes to characterize the genetic differentiation and conduct the phylogenetic analysis and divergence time estimation of the 17 Parnassius species collected in China. Species identification and genetic differentiation analysis suggest that the ITS barcode is an effective marker for Parnassius species identification; additionally, a relatively high level of genetic diversity and low level of gene flow were detected in the five Parnassius species with diverse geographic populations. Phylogenetic analysis indicates that the 17 species studied were clustered in six clades (subgenera), with subgenus Parnassius at the basal position in the phylogenetic trees. Bayesian divergence time estimation shows that the genus originated about 18 million years ago during the early Miocene, correlated with orogenic events in the distribution region, probably southwestern China about 20–10 million years ago. Our estimated phylochronology also suggests that the Parnassius interspecific and intraspecific divergences were probably related with the rapid rising of the Qinghai-Tibet Plateau, the Tibet Movement, the Kunlun-Yellow River Tectonic Movement, and global cooling associated with intensified glaciation in the region during the Quaternary Period.

Authors: Mirhashemi AmirHossein , Arab Sepideh , Bahrami Rashin 
Published: October 2020

Background and Objective: sleep apnea is a disorder in which the person's breathing is interrupted periodically at night due to the physical blockage of the airway. Determining the best way to treat their sleep disorders requires careful studies, tests, counseling and various examinations. Orthodontics is the best way to get a patient to have oral equipment. The use of orthodontic equipment is a non-surgical and effective treatment for mild to moderate sleep apnea. The aim at this study is a systematic review and meta-analysis of orthodontics as a therapeutic tool for managing sleep apnea.
Methods: At first, all the papers (n=112) related to keywords (orthodontics therapeutic tools and sleep apnea) were searched for English databases; Google, Google scholar, PubMed, Embase, CINAHL, PsycInfo, and Cochrane Database of Systematic Reviews covering the period from 2010 through 2019 was studied. Then, papers related to orthodontics therapeutic tools of sleep apnea were selected and analyzed (n=8).As a result to inclusion and exclusion criteria, papers related to orthodontics therapeutic tools of sleepapnea were found and analyzed (n=8). Predefined inclusion and exclusion criteria were: papers related to orthodontics therapeutic tools of sleepapnea, papers were English, papers were original and all the papers were free full text.
Results: In the initial search, 112 papers were found that after reviewing the titles and abstract articles and removing repetitive and non-related ones, 26 possible related articles were investigated. Of these, 18 papers were omitted from the abstract because of lack of access to the original article and lack of sufficient information. Finally, 8 papers were included in the study. Data were collected based on study characteristics, measures of orthodontics therapeutic tools, prevalence rates and factors associated with sleep apnea. Orthodontics therapeutic tools for sleep apnea are very important and can play very significant role in health improvement. So, paying more attention to benefits of orthodontics therapeutic tools in sleep apnea is necessary. On important points is the orthodontist’s active role play in screening the patients for this disease and advice oral appliance therapy, if needed.
Conclusion: The most effective treatment for sleep apnea and snoring is orthodontics therapeutic tools. Orthodontics therapeutic tools are effective treatments for sleep apnea, snoring and night snoring. Orthodontics therapeutic tools are low cost, easy to use, portable and need little maintenance.
A Novel Method for Accurate Preoperative Templating for Total Hip Arthroplasty Using a Biplanar Digital Radiographic (EOS) System

Published: October 2020

Background:
Accurate preoperative planning for total hip arthroplasty (THA) relies on conventional anteroposterior radiographs. The difficulty of determining the magnification factor of radiographs is a major limitation. Despite the use of markers for calibration, identifying the plane of the hip joint is a major challenge. The aim of this study was to evaluate the accuracy of a novel method for image calibration and preoperative planning in THA involving the use of a biplanar radiographic (EOS imaging) system and a self-designed coin device.

Methods:
Biplanar radiographs (with the self-designed coin device) and a conventional anteroposterior radiograph (with a coin) were made for 26 patients after primary THA. The agreement between the actual and calculated diameters for each method was assessed using the concordance correlation coefficient (CCC) and Bland-Altman plots. In addition, 15 patients undergoing primary THA were prospectively enrolled to evaluate the EOS imaging-based method (EOS method), with biplanar radiographs made with use of the coin device. The accuracy of the preoperative predicted size of the implants was evaluated.

Results:
Both the EOS and conventional anteroposterior radiograph-based methods were reliable in repeated measurements of the diameter of the artificial femoral head in the reproducibility study, with the average CCCs for both methods >0.990. The agreement between the actual and EOS-based calculated diameters of the artificial femoral head was excellent, with a CCC of >0.990, while the agreement was poor between the actual and anteroposterior radiograph-based calculated diameters, with a CCC of <0.75. The EOS method exhibited a lower absolute difference (0.09 ± 0.07 mm) between the actual and calculated diameters compared with conventional anteroposterior radiography (1.26 ± 0.86 mm) (p < 0.001). EOS-based preoperative plans also exhibited excellent performance on the accuracy of the planning of the cups and stems; only 1 patient (6.7%) had a final implanted cup that differed by 1 size from the predicted size. Two patients (13.3%) had final implanted stems that differed by 1 size from the predicted size, and for 1 patient (6.7%), the stem size was off by ≥2 sizes.

Conclusions:
We describe a novel and easy-to-use method for the accurate calibration of radiographs and preoperative planning for THA. The EOS method evaluated in this study is an alternative method for preoperative planning in clinical practice.
