This article is devoted to the question of constructing a regression model, which will make it possible to analyze and predict the outcome of e-sports meetings in the DOTA 2 discipline using the Virtus Pro team as an example. In addition, throughout the text, a brief analysis of the e-sports industry these days, as well as a brief explanation of the essence of the chosen e-sports discipline are taken into consideration. Convincing arguments are presented that make it possible for the reader to understand that e-sports today can equal traditional sports in the following indicators: the number of followers, peak views as well as the amount of money circulating in the industry. The law introduced during the research is intended for the following external users: e-sports organizations, potential investors, breeders as well as for the players themselves. The resulting model was analyzed and described using various statistical indicators. A correlation grid was obtained, indicators of regression statistics were described, analysis of variance was made with a detailed description of its results. Factor signs considered during the research are described in detail for reader’s understanding. It is important to note that the resulting law makes it possible to apply it not only to the object of study, but also to other e-sports organizations having a team in this discipline, provided that their styles of playing the game have similarities. The tool for deriving the regression law was Microsoft Excel. The source of data is the team’s statistics, which were collected during real e-sports meetings by the leading site of statistics and the gaming community DOTA 2 — Dotabuff.

This article focuses on the problematic issues that arise in the process of appointing a forensic handwriting examination, where the object of study are manuscripts performed in a state of intoxication. The reliability of the conclusions will largely depend on the correct quality and sufficient quantity of comparative material. This will be possible if the initiator of the study, after careful consideration of their work, qualitatively selects comparative material for the study. The purpose of this article is to further improve the purpose of forensic handwriting examination, the object of which is the study of manuscripts made in a state of intoxication, as well as to provide practical recommendations that will allow the initiators of the study to correctly select comparative material. Of particular importance in the conduct of forensic handwriting diagnostic examinations are information from the case file relating to the subject of examination, ie in the resolution, decision or statement must be indicated: first, it is information about the person - the actual or intended executor of the manuscript; second, essential information relating to the situation, the situation in which the manuscript in question was presumably performed, and in connection with it, the possible psychological attitude or emotional state of the person writing. When the initiator of the study informs the expert of the necessary information, he should not be afraid to "impose" a certain version, because the method of expert research is based on checking all the most likely alternatives (versions and counter version) and making decisions based only on objective data. Regarding the selection of comparative material provided for research in establishing whether a person was intoxicated, there are some peculiarities in the selection of experimental samples, because we cannot bring a person in such a state to take the necessary samples because the law prohibits harm to health, humiliation and infliction of moral suffering. They can be obtained without violating the law, by changing the condition, namely, you need to dictate the text at an extremely fast pace. The expert may also make a request, although the initiator of the study provided comparative material such as free, conditionally free and experimental samples, because there may be concomitant factors that the initiator did not take into account when selecting, such as experimental samples. The expert's request should be treated responsibly because the quality of the expert's opinion may depend on how well it is executed.

Abstract Introduction The CLSI EP15-A3 guideline “User Verification of Precision and Estimation of Bias” provides a simple experimental approach to estimate a method’s imprecision and bias. The objective is to determine if the laboratory precision performance of repeatability (SR) and within-laboratory imprecision (SWL) are in accordance to the manufacturer specification claims (MSCs). Objectives Evaluate the utility of the EP15-A3 protocol to verify method precision during a troubleshooting investigation and after major instrument maintenance, using a carcinoembryonic antigen (CEA) immunoassay as an example. Methods CEA was performed on the Beckman Coulter DxI (Beckman Coulter, Brea, CA). Quality control (QC) levels (L1: 2.89; L2: 21.10; L3: 39.10 ng/mL) (Bio-Rad Laboratories, Irvine, CA) were used. Each QC level was measured before and after instrument maintenance as follows: five replicates per run, one run per day, and during 5 days. Imprecision estimates (IEs) for SR (%CVR) and SWL (%CVWL) were calculated by one-way analysis of variance using Microsoft Excel Analyse-it software. Estimated imprecision was compared to MSC and desirable imprecision specifications based on biological variation (BV). Results A change in the analytical performance of CEA was detected by a decreased sigma-metric indicator. After a bias problem was ruled out, the observed %CVR for L1, L2, and L3 were 7.2%, 3.7%, and 4.8%, respectively. The %CVWL were 8.3%, 5.0%, and 5.5%, which exceeded the MSC of %CVWL~4.0% to 4.5%. After a laboratory investigation, major instrument maintenance was performed by the manufacturer. The %CVR and %CVWL estimates for L1, L2, and L3 after maintenance were 3.2%, 3.8%, 3.5% and 3.9%, 4.2%, 4.0%, respectively. After maintenance, the CEA performance was consistent with the MSC for each of the levels analyzed and within the BV impression goal of %CV ≤6.4. Conclusion CLSI EP15-A3 guideline is an alternative troubleshooting tool that can be used to investigate and verify method precision performance before and after significant instrument maintenance.

Abstract Objectives We aim to report the simultaneous effect of different protein and lipid concentrations on sodium (Na+) and potassium (K+) measurement by direct and indirect ion selective electrodes (dISE and iISE) in patient samples. Materials and Methods Na+ and K+ were measured in 195 serum samples received in the laboratory using iISE by Roche Modular P800 autoanalyzer and using dISE by XI-921 ver. 6.0 Caretium electrolyte analyzer. Serum total protein (TP), cholesterol (Chol), and triglycerides (TG) were measured using conventional photometric methods on Roche Modular P800 autoanalyzer. Differences for each pair of results for Na+ (Diff_Na+ = [Na+ dISE–Na+ iISE]) and K+ (Diff_K+ = [K+ dISE–K+ iISE]) were calculated. Patient subgroups with high, normal, or low TP (< 5, 5–7.9, or ≥ 8 g/dL), Chol (< 150, 150–299, or ≥300 mg/dL), or TG (< 150, 150–299, or ≥300 mg/dL) were compared using analysis of variance. Note that 95% confidence interval of Diff_Na+ and Diff_K+ were calculated to see the number of samples showing clinically significant differences. Results Diff_Na+ (p = 0.007) and Diff_K+ (p = 0.002) were found significant between samples with normal and high TP. However, effect of TG was not significant. Chol concentration affected Diff_Na+ significantly between low versus normal (p = 0.002), and high versus normal (p = 0.031) Chol groups. Diff_K+ was significant (p = 0.009) between low versus normal Chol. Clinically relevant disagreement of ≥|5| mmol/L for Na+ was observed in high percentage of samples including all subcategories; however, for K+ only 3.6% of the total samples showed disagreement of ≥ |0.5| mmol/L. A multivariate regression equation based on fit regression model was also derived. Conclusion Summarily, interchangeable use of electrolyte results from dISE and iISE is not advisable, especially in a setting of hyperproteinemia (≥8 g/dL) or hypercholesterolemia (≥300 mg/dL); more so for Na+.

Roaster chicken carcasses (2,928) were collected from the evisceration line of a poultry abattoir over a 5-month period and identified as to the lot (truck load) and supplier. Bacterial load was determined by mechanically rinsing each eviscerated carcass in sterile water and then using an automated hydrophobic grid membrane interpreter system to obtain the log10 most probable number of aerobic bacteria per gram of carcass. Analysis of variance demonstrated that the between-carcass, between-lots-within-supplier, and between-supplier components of variability in bacterial load represented 73.2, 14.2, and 12.6% of the total variability, respectively. There was a significant (p &lt; 0.001) supplier and lots-within-supplier effect on bacterial load of carcasses. A regression model demonstrated that bacterial load of lots significantly (p ≤ 0.05) decreased with increasing hours of operation of the evisceration line. Factors in the model which were significantly (p ≤ 0.05) associated with increased bacterial load included longer crating and holding times, higher visible contamination scores, slaughter during winter months, higher outdoor temperatures, and slaughter of lots composed of only pullets. The model explained about 23% of the variability in bacterial load.

The rise in consumer and corporate interest in action sports, also known as extreme sports, has been phenomenal. The apparent popularity of action sports, when combined with the sponsorships, endorsements, and advertising dollars they have quickly garnered, lends itself to scientific inquiry regarding the level and nature of public interest. The purpose of this study was to examine Generation Y's perceptions of action sports, with a specific focus on the expressed popularity of action sports and the relationship between action sports interest and use of the media. The 39-item Action Sports Questionnaire (ESQ) was constructed to examine Generation Y perceptions of action sports, sports related viewing preferences, and sports related media usage among middle and high school aged students. The present findings suggested that these members of the Generation Y(n= 367) niche market preferred action sports over the traditional sports of basketball and baseball. Respondents also indicated stronger preference for soccer, but would prefer to watch the X-Games over the World Cup. There is an indication that soccer and action sports are more popular among the younger generation than some traditional team sports. Males were slightly more supportive that action sports would become more popular in the future, and the male respondents were likewise more familiar with action sports. More members of Generation Y watch action sports than their predecessors, and they likewise tend to be optimistic about the future of action sports if they watch events on television.
