Published: May 2017

Inverted list compression is a topic that has been studied for 50 years due to its fundamental importance in numerous applications including information retrieval, databases, and graph analytics. Typically, an inverted list compression algorithm is evaluated on its space overhead and query processing time. Earlier list compression designs mainly focused on minimizing the space overhead to reduce expensive disk I/O time in disk-oriented systems. But the recent trend is shifted towards reducing query processing time because the underlying systems tend to be memory-resident. Although there are many highly optimized compression approaches in main memory, there is still a considerable performance gap between query processing over compressed lists and uncompressed lists, which motivates this work.
In this work, we set out to bridge this performance gap for the first time by proposing a new compression scheme, namely, MILC (memory inverted list compression). MILC relies on a series of techniques including offset-oriented fixed-bit encoding, dynamic partitioning, in-block compression, cache-aware optimization, and SIMD acceleration. We conduct experiments on three real-world datasets in information retrieval, databases, and graph analytics to demonstrate the high performance and low space overhead of MILC. We compare MILC with 12 recent compression algorithms and experimentally show that MILC improves the query performance by up to 13.2× and reduces the space overhead by up to 4.7×.

Published: May 2017

Abstract
In this paper, we compute explicitly the oscillation constant for certain half-linear second-order differential equations having different periodic coefficients. Our result covers known result concerning half-linear Euler type differential equations with α—periodic positive coefficients. Additionally, our result is new and original in case that the least common multiple of these periods is not defined. We give an example and corollaries which illustrate cases that are solved with our result.

Loan pricing under estimation risk
Authors: Neuberg Richard , Hannah Lauren 
Published: May 2017

Abstract
Financial product prices often depend on unknown parameters. Their estimation introduces the risk that a better informed counterparty may strategically pick mispriced products. Understanding estimation risk, and how to properly price it, is essential. We discuss how total estimation risk can be minimized by selecting a probability model of appropriate complexity. We show that conditional estimation risk can be measured only if the probability model predictions have little bias. We illustrate how a premium for conditional estimation risk may be determined when one counterparty is better informed than the other, but a market collapse is to be avoided, using a simple example from pricing regime credit scoring. We empirically examine the approach on a panel data set from a German credit bureau, where we also study dynamic dependencies such as prior rating migrations and defaults.

Diving in to new materialist theory, this paper explores what might be learnt at a public swimmingpool, through poetry as arts-based research. Writing, sitting, thinking and swimming, the learnerenters new spaces and atmospheres, where learning emerges as unpredictable and involving awhole range of human and non-human bodies. Public spaces, where we can think about causalityand design without the strictures of school curriculum, may emerge as key sites for new understandings of learning where abiding humanist preoccupations can slip away. While this papercannot offer the physical and material movement, touching, flesh, smelling, silicone, cotton andwater of the poem as performed at the Public Pedagogies Institute conference in Melbourne in2015, readers can still be prepared to get changed!

Authors: Matuzevičiūtė Giedrė Motuzaitė , Telizhenko Sergey 
Published: May 2017

This paper presents the results of archaeobotanical investigations performed during excavations of a Linear Pottery Culture (LBK) site in western Ukraine. The collection of cultivated plants and weeds found in the hearth of the LBK dwelling fits well with what was grown by LBK inhabitants elsewhere in Europe. The direct dating of cereal grains reveals the existence of early-stage LBK in Ukraine during a much earlier timeframe than previously thought. The new archaeobotanical results and their dates exclude other previously postulatedtheories on the timing and geographical origins of agriculture in Ukraine, pointing towards the western LBK phenomenon as the earliest carrier of crop cultivation to Ukraine.

Many authors noticed the actuality of fish hematological parameters usage as indices of anthropogenic influence. Blood system reflects the reaction of the body on the action of different ecological factors. The problem of heavy metals influence on hematological parameters of silver cap (Hypopthalmichtys molitrix) needs to be investigated. The aim of the work was studying of ecotoxical Plumbum and Cadmium influence on hematological indices of silver carp (Hypopthalmichtys molitrix) during the period exposition. The results of the investigations concerning the influence of Plumbum and Cadmium on some hematological indices of silver carp (Hypopthalmichtys molitrix) for 12 days exposition up to the action of these heavy metals are given in this article. Experimental part was realized at the Lviv research station of Institute of fisheries NAAS (Lviv oblast, Horodok region, Velykyi Lyubin). Experimental groups contained 10 two-years individuals each. Fish were adopted to laboratory conditions for 5 days under the temperature 19 ± 2ºС, рН = 7.3 ± 0.2, oxygen content 7–8 mg/l. Blood parameters were measured on the sixth and twelfth days at the control group and groups which were under the influence on the level of 2 and 5 MPC of the appropriate metal. It was proved that the influence of Plumbum and Cadmium causes the lowering of erythrocytes number, hemoglobin and corpuscular volume: the effect becomes stronger when he concentration increases and in time. The effect from intoxication by Cadmium comes faster than by Plumbum.

The influence of bullock`s different breeding value for reproductive ability and milk production of their daughters were investigated. Established that the age of first productive insemination of heifers Ukrainian black spotted milk breed, was 17.5–18.6 months and age of first calving – 26.6–27.8 months. Heifers` live weight at the first insemination was 361.4–407.1 kg. During first lactation the highest productivity had daughters from parents with breeding value by milk yield more than 801 kg. In the first lactation wasn’t found significant difference in duration service-period and interparturition-period for cows derived from progenitors with different breeding value. In the second lactation best indexes in duration service-period and interparturition-period for cows derived from progenitors with breeding value by milk yield 601–800 kg and more than 801 kg. In the third, the highest lactation, these indexes were best for cows derived from progenitors with breeding value by milk yield 601–800 kg. The difference in milk yield during first lactation between heifers received from progenitors with breeding value by milk yield less than 200 kg and heifers from bullock`s with breeding value 401–600 kg was 292 kg. The difference in milk yield between heifers received from progenitors with breeding value by milk yield less than 200 kg and heifers from bullock`s with breeding value with breeding value 601–800 kg was 660.3 kg. The difference in milk yield between heifers received from progenitors with breeding value by milk yield less than 200 kg and heifers from bullock`s with breeding value more than 801 kg was 920.8 kg In the second lactation this difference was 589.8 (Р < 0.001), 841.5 (Р < 0.001) і 894.4 (Р < 0.001) kg of milk, in the third, the highest lactation – 754.5 (Р < 0.001), 951.8 (Р < 0.001) і 1335.7 кг (Р < 0.001).

Published: May 2017

It is well known with an increase of milk productivity of cows their reproductive capacity in general became worse. Therefore, it is important to establish optimal parameters of the first age insemination and first calving, duration of service- and inter-calving periods. In view of the above, the purpose of our researches was to study the influence of reproductive capacity parameters of Simmental cows on the formation of milk productivity. The study were conducted on 331 cows in agricultural LLC «Litynskyy» Drohobych raion, Lviv oblast. Evaluation of milk productivity and reproductive capacity of the animals (in 20 years) were performed according to the data of zootechnical accounting for the first, second, third and the best lactations. The differences in rates of milk productivity depending on the parameters of their reproductive capacity were established. Animals with age of first fruitful insemination 18.1–20.0, with first calving age – 27.1–29.0, duration of service period – 101–120 and duration of the inter-calving period – 381–400 days had the best yields and the highest quantity of milk fat. According to the above mentioned indicators of milk productivity they are likely dominated by animals with bigger or smaller indicators of reproductive capacity, but in most cases, this advantage was unreliable. It was found positive highly significant links between indicators of reproductive capacity of cows and milk yield. The highest correlation coefficients were observed between age of first calving and their milk yields, depending on lactation, they were 0.380–0.498, lower – between age of first insemination and milk yield – 0.316–0.456 and the lowest – between service- and inter-calving periods and yield – 0.124–0.335; 0.127–0.331 respectively. The impact of the abovementioned indicators on yield was within 23.13–39.88; 28.63–45.02; 30.98–35.17%, respectively.

Published: May 2017

The analysis of publication related to the usage of embryo transplantation method in breeding sheep had been conducted. It is proved that the theoretical basis of the method of embryo transplantation is the large number of germ cells in the ovaries of females, most of which during the usual method of reproduction does not participate in these processes, and the high probability of inheriting genetic characteristics of embryos after transplantation by recipient. On this basis, from females throughout her life we can get a few dozen of descendants. The main aspects of embryos transplantation technology is to development of new methods that will ensure obtaining of the greatest number of good-quality embryos with desirable genotypes, both by the induction of multiple ovulation and by cultivation of follicular oocytes outside the body. It has been defined, that its usage is limited by a number of factors that are not well studіed and many of them are contradictional, in particular unpredictable results of the multiple ovulation induction. The development of the method of predicting the results of polyovulation will significantly increase the efficiency of embryos transplantation and significantly reduce the cost of labor and financial resources. It has been shown, that one of the main factors of making transplantation more practical is to develop the methods of embryos cryopreservation. This will simplify the selection of recipients and donors by the sexual cycle, will further long distance transportation and will enable the transplantation in the planned breeding herds. The further of the method, along with modern advances of genetics, embryology, endocrinology, will in the near future lead to develop a comprehensive method for the accelerated creation in sheep breeding flocks of high performance animals.

The influence of probiotic «Monosporin» on the growth performance of piglets using feed rations varying degrees of balance. Is defined nutrients of basic ratio which is used at the farm, and normalized by the inclusion of corn bran and premix «Tekro». It is shown that the use of the basic diet with probiotic live weight of piglets increased by 1.3% and the average daily weight gain of animals – by 1.7–2.3% over the control. By using normalized diet with probiotic preparations value of body weight and daily weight gain of young pigs increased by 13.2–18.7% and 19.4–39.2% respectively. Comparison of productivity indices of piglets who consumed diets normalized without probiotics and with probiotic, indicates a an increase of 3.0–6.5% and 7.5–11.7% in favor of the latter. Along with the increase of animal growth performance using normalized diets with probiotic preparation «Monosporin» costs of fodder units per 1 kg of gain is reduced by 25.3%. The results indicate that the effect of the use of probiotics is associated with the fact that increases the digestibility of feed, improving their digestibility, it activates the body's metabolism, stimulates the synthesis of amino acids, vitamins, enzymes and antibiotic substances that suppress pathogens and increase the overall resistance of the animal organism to viral diseases and various adverse (stressful) factors. In assessing the cost efficiency of using normalized ration with the addition of premix TM «Tekro» and probiotic «Monosporin» shows that in complex their application the best result is observed: the level of profitability of 47.7%, and the profit from the sale of 1 head – 185.09 UAH. While the profitability of pork production of using probiotic together with the basic feed ration is 7,8%.

The materials of the article the analysis of periodic research reports on prospects of feed «Aller Aqua» in the diet of rainbow trout. Overview conceptual experience of increasing the volume of production of this important sector of agricultural production as the breeding and rearing of trout. Trout industry is the most productive direction of the coldwater aquaculture. Costs highly specialized feed for growing trout reach 70% of the total cost of the fish, so the features of feeding, nutritional feed and cultivation technology is relevant and of interest to manufacturers. Today on the Ukrainian market sales volume of feed for trout is a leading foreign firms: Aller Aqua, Biomar, Skretting and others. The quality of the manufactured products of domestic manufacturers often inferior to the requirements of the feed for trout, as domestic production is not always withstand competition. Therefore, at the present rate of trout industry as a promising field of fish farming, and the corresponding demand for feed for valuable fish species such high dependence on imports, now greatly reduces the volume of cold-water aquaculture cultivation sites that accordingly obliges producers special animal feed to improve their quality. The basis of our research is tasked with optimizing normalized using feeding trout feed «Aller Aqua» and results analysis and comparative characteristics of growing trout using Ukrainian feed manufacturers. Purpose is to clarify the nature of the impact of feed «Aller Aqua» and physiological metabolism, growth, development, reproduction and obtaining marketable products rainbow trout that could be the basis for conclusions about the appropriateness and use of feed rules «Aller Aqua», and the possibility of alternative feed means in terms of economy.

Published: May 2017

On the first stage experiments are conducted by the aim of establishment on how many higher the real indexes of fresh sperm and dilute protective environments after moving away of cellular debris, extraneous cages and dead cages. On the second stage, comparison of basic physiological indexes of the fertilization faction got from deconservation sperm and compared to the corresponding indexes of з sperm was conducted, that was not subject to the special cleansing procedure. Difference between research and control groups, in relation to survivability of sperm and index of absolute survivability of sperm was statistically reliable (Р < 0,001), as for fresh sperm so for sperm, that carried freezing and thawing in liquid nitrogen. Faction of sperm, that has impregnating ability potentially, as fresh sperm so that was subject to freezing and thawing substantially differ in the row of biological indexes of sperm, that creates the necessity of introduction of new additional descriptions for the analysis of sperm. Index of survivability of sperm, that potentially has impregnating ability at deconservation sperm rose on three hours or on a 32,8 percent’s . Index of absolute survivability of sperm, that potentially has impregnating ability rose on 8,19 conditional units. The modernized method of estimation of quality of sperm of bulls is offered. It is set that treatment of sperm with the use of gradients of closeness exceeds the indexes of activity, to survivability and absolute survivability as at fresh standards of sperm so at deconservation standards of sperm, that gives an opportunity more objectively to describe quality of sperm. Results over of researches of biological quality of sperm of bulls of meat blackly-pied and red-pied suckling breed are brought depending on the method of treatment of tests. Additional descriptions of analysis sperm are entered, they can become the major criteria of estimation of full value and impregnating ability.
