Cannabis Concentrate Use in Adolescents
Authors: Meier Madeline H. , Docherty Meagan , Leischow Scott J. , Grimm Kevin J. , Pardini Dustin
Published: August 2019

BACKGROUND:

Cannabis concentrates, which are cannabis plant extracts that contain high concentrations of Δ-9-tetrahydrocannbinol (THC), have become increasingly popular among adults in the United States. However, no studies have reported on the prevalence or correlates of cannabis concentrate use in adolescents, who, as a group, are thought to be particularly vulnerable to the harms of THC.

METHODS:

Participants are a racially and ethnically diverse group of 47 142 8th-, 10th-, and 12th-grade students recruited from 245 schools across Arizona in 2018. Participants reported on their lifetime and past-month marijuana and cannabis concentrate use, other substance use, and risk and protective factors for substance use problems spanning multiple life domains (ie, individual, peer, family, school, and community).

RESULTS:

Thirty-three percent of all 8th-, 10th-, and 12th-graders reported lifetime cannabis use, and 24% reported lifetime concentrate use. Seventy-two percent of all lifetime cannabis users had used concentrates. Relative to adolescent cannabis users who had not used concentrates, adolescent concentrate users were more likely to use other substances and to experience more risk factors, and fewer protective factors, for substance use problems across numerous life domains.

CONCLUSIONS:

Most adolescent cannabis users have used concentrates. Based on their risk and protective factor profile, adolescent concentrate users are at higher risk for substance use problems than adolescent cannabis users who do not use concentrates. Findings raise concerns about high-risk adolescents’ exposure to high-THC cannabis.
Word Embedding as Maximum A Posteriori Estimation
Authors: Jameel Shoaib , Fu Zihao , Shi Bei , Lam Wai , Schockaert Steven
Published: August 2019

The GloVe word embedding model relies on solving a global optimization problem, which can be reformulated as a maximum likelihood estimation problem. In this paper, we propose to generalize this approach to word embedding by considering parametrized variants of the GloVe model and incorporating priors on these parameters. To demonstrate the usefulness of this approach, we consider a word embedding model in which each context word is associated with a corresponding variance, intuitively encoding how informative it is. Using our framework, we can then learn these variances together with the resulting word vectors in a unified way. We experimentally show that the resulting word embedding models outperform GloVe, as well as many popular alternatives.
Predicting the Argumenthood of English Prepositional Phrases
Authors: Kim Najoung , Rawlins Kyle , Van Durme Benjamin , Smolensky Paul
Published: August 2019

Distinguishing between arguments and adjuncts of a verb is a longstanding, nontrivial problem. In natural language processing, argumenthood information is important in tasks such as semantic role labeling (SRL) and prepositional phrase (PP) attachment disambiguation. In theoretical linguistics, many diagnostic tests for argumenthood exist but they often yield conflicting and potentially gradient results. This is especially the case for syntactically oblique items such as PPs. We propose two PP argumenthood prediction tasks branching from these two motivations: (1) binary argumentadjunct classification of PPs in VerbNet, and (2) gradient argumenthood prediction using human judgments as gold standard, and report results from prediction models that use pretrained word embeddings and other linguistically informed features. Our best results on each task are (1) acc. = 0.955, F1 = 0.954 (ELMo+BiLSTM) and (2) Pearson’s r = 0.624 (word2vec+MLP). Furthermore, we demonstrate the utility of argumenthood prediction in improving sentence representations via performance gains on SRL when a sentence encoder is pretrained with our tasks.
A Unified Model for Opinion Target Extraction and Target Sentiment Prediction
Authors: Li Xin , Bing Lidong , Li Piji , Lam Wai
Published: August 2019

Target-based sentiment analysis involves opinion target extraction and target sentiment classification. However, most of the existing works usually studied one of these two sub-tasks alone, which hinders their practical use. This paper aims to solve the complete task of target-based sentiment analysis in an end-to-end fashion, and presents a novel unified model which applies a unified tagging scheme. Our framework involves two stacked recurrent neural networks: The upper one predicts the unified tags to produce the final output results of the primary target-based sentiment analysis; The lower one performs an auxiliary target boundary prediction aiming at guiding the upper network to improve the performance of the primary task. To explore the inter-task dependency, we propose to explicitly model the constrained transitions from target boundaries to target sentiment polarities. We also propose to maintain the sentiment consistency within an opinion target via a gate mechanism which models the relation between the features for the current word and the previous word. We conduct extensive experiments on three benchmark datasets and our framework achieves consistently superior results.
Unsupervised Post-Processing of Word Vectors via Conceptor Negation
Authors: Liu Tianlin , Ungar Lyle , Sedoc João
Published: August 2019

Word vectors are at the core of many natural language processing tasks. Recently, there has been interest in post-processing word vectors to enrich their semantic information. In this paper, we introduce a novel word vector post-processing technique based on matrix conceptors (Jaeger 2014), a family of regularized identity maps. More concretely, we propose to use conceptors to suppress those latent features of word vectors having high variances. The proposed method is purely unsupervised: it does not rely on any corpus or external linguistic database. We evaluate the post-processed word vectors on a battery of intrinsic lexical evaluation tasks, showing that the proposed method consistently outperforms existing state-of-the-art alternatives. We also show that post-processed word vectors can be used for the downstream natural language processing task of dialogue state tracking, yielding improved results in different dialogue domains.
Learning Personalized End-to-End Goal-Oriented Dialog
Authors: Luo Liangchen , Huang Wenhao , Zeng Qi , Nie Zaiqing , Sun Xu
Published: August 2019

Most existing works on dialog systems only consider conversation content while neglecting the personality of the user the bot is interacting with, which begets several unsolved issues. In this paper, we present a personalized end-to-end model in an attempt to leverage personalization in goal-oriented dialogs. We first introduce a PROFILE MODEL which encodes user profiles into distributed embeddings and refers to conversation history from other similar users. Then a PREFERENCE MODEL captures user preferences over knowledge base entities to handle the ambiguity in user requests. The two models are combined into the PERSONALIZED MEMN2N. Experiments show that the proposed model achieves qualitative performance improvements over state-of-the-art methods. As for human evaluation, it also outperforms other approaches in terms of task completion rate and user satisfaction.
Application of Genetic Algorithm for Optimization of Heat-Transfer Parameters
Authors: AKPINAR Mustafa
Published: August 2019

Nowadays,
new materials are developed with the aim to reduce heat transfer and energy
loss. Thus, energy can be reduced and heat energy can be transferred
efficiently. Many researches on the field of heat transfer have been made in
the literature. However, there are few studies on the determination of
insulation material thickness using heuristic algorithms and there is no study
on finding the thermal boundary layer thickness using heuristic algorithms. One
of the heuristic algorithms used in the field of computer science is Genetic Algorithm
(GA), which is frequently applied in optimization problems. We propose that GA
could be used to solve heat transfer problems of insulation material selection
and laminar thermal boundary layer thickness determination. The goal of the
proposal is to estimate the optimal parameters using a GA. In the first case,
the thickness of insulation material selection and the maximum amount of heat
loss that can be caused by different thicknesses of the insulating material
under the boundary conditions and assumptions are calculated using GAs. It is
shown that, using the heat-transfer coefficient and unit length cylinder, GAs
can be used in everyday problems, such as determining the thickness of the
insulating material or the outer temperature of the insulating material. In the
second case, the boundary layer thickness is determined using GA for air flow
with a laminar flow, where its characteristics are constant, irradiation is
neglected, and plate and air temperatures are constant in the continuous regime
on the plate. For both cases, the GA results are repeated 5 times and it is
observed that the results are very close to each other. The experimental
results demonstrate that, for both cases GA gives optimal target, minimum and
maximum values, thus, GAs are applicable in heat-transfer problems that require
optimization.
Morphological phylogeny of Megachilini and the evolution of leaf-cutter behavior in bees (Hymenoptera: Megachilidae)
Authors: Gonzalez Victor H. , Gustafson Grey T , Engel Michael S
Published: August 2019

A unique feature among bees is the ability of some species of Megachile Latreille s.l. to cut and process fresh leaves for nest construction. The presence of a razor between the female mandibular teeth (interdental laminae) to facilitate leaf-cutting (LC) is a morphological novelty that might have triggered a subsequent diversification in this group. However, we have a limited understanding of the phylogeny of this group despite the large number of described species and the origins and patterns of variations of this mandibular structure are unknown. Herein, using a cladistic analysis of adult external morphological characters, we explored the relationships of all genera of Megachilini and the more than 50 subgenera of Megachile s.l. We coded 272 characters for 8 outgroups and 114 ingroup species. Depending on the weighting scheme (equal or implied weighting), our parsimony analyses suggested the monophyly of Megachile s.l. and that either Noteriades Cockerell or the clade Coelioxys Latreille + Radoszkowskiana Popov is the extant sister group of all other Megachilini. In addition, we conducted Bayesian total-evidence tip-dating analyses to examine other possible hypotheses of relationships and patterns of variation of the interdental lamina. Our analyses suggest that interdental laminae developed asynchronicaly from two different structures in the mandible, and differ in their phenotypic plasticity. Character correlation tests using phylogenetic pairwise comparisons indicated that the presence of interdental lamina is not associated with head size, mandible size and shape, and pubescence on the adductor interspace. We discuss the implications of our findings for the classification of Megachilini and the development of novel evolutionary, ecological, and functional hypotheses on this behavior. New taxa established are Pseudoheriadini Gonzalez & Engel, new tribe, Ochreriadini Gonzalez & Engel, new tribe, Cremnomegachile Gonzalez & Engel, new genus, Rozenapis Gonzalez & Engel, new genus, and Saucrochile Gonzalez & Engel, new genus, along with the following new combinations: Cremnomegachile dolichosoma (Benoist), new combination, Rozenapis ignita (Smith), new combination, and Saucrochile heriadiformis (Smith), new combination.
A new genus of augochlorine bees from northern Venezuela (Hymenoptera: Halictidae)
Authors: Engel Michael S.
Published: August 2019

A new genus and species of the bee tribe Augochlorini (Halictinae) is described and figured from northern Venezuela.  Trichommation osculans Engel, new genus and species, is a member of the Megaloptidia-group of genera as evidenced by the narrow and elongate mouthparts and sharply pointed galeal apex.  The genus is most similar to Megommation Moure and Megaloptidia Cockerell, particularly in the enlarged ocelli present only in these genera among those in the group.  Aside from intermingling traits of both of these genera, Trichommation is further distinct from both owing to the presence of ocular setae, a pectinate inner metatibial spur, and basal rugae on the basal area of the propodeum.  Emendations to the key to genera of the Megaloptidia group are provided to allow for the identification of Trichommation.

Perioperative management of patients with rheumatic disorders: problems and solutions
Authors: Klimenko A. A. , Kondrashov A. A.
Published: August 2019

Currently management of patients with rheumatic disorders (RD) involves not only application of all of the known spectrum of mediations in accordance with current guidelines and algorithms but also timely use of high-tech medical care, for example, endoprosthesis of the large joints, spinal surgery, dental care, endovascular surgery, aimed at decreasing the level of disability and improving patients’ quality of life. The article considers modern approaches to management of patients with RD in the perioperative period, special emphasis is given to administration of background anti-inflammatory and genetically engineered biological medications, as well as prevention of thrombosis of the deep veins and thromboembolic complications. In the postoperative period, use of pharmacological control of development of “painful endoprosthesis” is vital as it is the main cause of unsatisfaction with the outcome of orthopedic aid. An effective method for controlling pain syndrome in patients with RD is use of non-steroidal anti-inflammatory drugs (NSAIDs). Selection of a specific NSAID should be based on the knowledge of gastrointestinal and cardiovascular side effects, as well as evidence of effectiveness in the perioperative period. In the group of patients with RD, namely with ankylosing spondylitis and psoriatic arthritis, prevention of heterotopic ossification after orthopedic manipulations, endoprosthesis is very important. Considering high comorbidity in RD, it is necessary to determine perioperative risk taking into account patient’s condition and operative urgency: to evaluate clinical features of the main and concomitant disorder (ischemic heart disease, cerebrovascular pathology, diabetes mellitus, chronic kidney disease), type of the surgery, results of electrocardiogram at rest, lab tests, and other noninvasive procedures. Correct planning of management of the perioperative period in patients with RD, adequate pain relief prior to surgery and after it, early activization are the main elements of rehabilitation of patients with pathologies of the locomotor apparatus.

Published: August 2019

Coronary heart disease is the leading cause of death worldwide. Over the past few decades, life expectancy has increased, which has led to an aging population in developed countries, so the average age of patients with acute coronary syndrome (ACS) has steadily increased in recent decades. The inclusion of elderly and senile patients in randomized clinical trials does not reflect the age-related association of these diseases. However, antithrombotic therapy and interventional treatment are the basis of treatment in patients with ACS of any age, including the elderly. For older patients, there may be a mismatch between chronological and biological age. The question of how close the treatment of elderly patients with ACS is to the level of current recommendations and whether it is possible to apply them unconditionally in this group of patients does not have a definite answer. Current recommendations and the underlying randomized clinical trials are focused on any one disease, whereas in the elderly in most cases multimorbid pathology occurs. In general, elderly patients with ACS should be treated using the same methods as younger patients, however, the presence of comorbid diseases in an elderly patient naturally increases the risk of complications, makes the patient’s prognosis heavier, significantly affects treatment tactics, limits the possibility of using conventional approaches when choosing a drug therapy.

Authors: Izmozherova N. V. , Popov A. A. , Sherstobitov V. E.
Published: August 2019

Objective: evaluation of the effectiveness of selection for coronary angiography of women who have applied to a cardiologist for thoracalgia and dorsalgia and regarded primarily as having a clinic of stable angina.

Materials and methods. 108 women (median age 59.5) applying to cardiologist due to chest pain were included in a cross-sectional study and underwent coronary angiography. Subjects with identified clinically significant atherosclerotic coronary lesions were compared to persons with intact coronary arteries.

Results. One-, two- and three-vessel lesions were diagnosed in accordingly 16; 21 and 26 % of patients. Intact coronary arteries were detected in 37 % subjects. In 17 of 40 persons with intact structure of the coronary arteries spasm of the coronary arteries was diagnosed. Odds ratio for atherosclerotic coronary arteries lesions in type 2 diabetic persons were 7.91 (1.74–36.00), for hypertension odds ratio 4.79 (1.52–15.01). Severe angina (3 and 4 functional class) was significantly more often diagnosed in women with identified coronary atherosclerosis. Severe coronary atherosclerosis was associated with absence of negative or doubtful results, whereas intact coronary vessels, negative and questionable results revealed more than half of the women. The obtained data reflect the relevance of the development of more effective algorithms for diagnosis of coronary artery disease in women, since the gender peculiarities of the formation of coronary atherosclerosis have been clearly confirmed in a number of large studies.

Conclusion. Medical history, physical load tests results, and subject’s emotional status should be evaluated to assess the feasibility of coronary angiography.

The paper discusses the concept of ethnic identity of the author. Various approaches to the study of the socio-biographical background of the author based on of his written speech aimed at solving and investigating crimes are analyzed. Peculiar features of the diagnostic study of the ethnic identity of the author are defined. The results of the study allow us to conclude that the author of an anonymous text can be referered to a specific ethnic group. Social groups were monitored on the Internet, and on the basis of an empirical analysis of the results obtained, a set of diagnostic features was identified, allowing the author of an anonymous text to be refferred to as an ethnic group of Kabardians. It is also noted that in modern conditions speech traces containing criminalistically significant information about the identity of the offender, are most often found in a digital form in blogs and social networks. It is noted that the need of operational investigative and investigative practice in obtaining and studying speech traces in the digital environment is increasing. It indicates the need for information and computer support for the study of products of speech activity. In this regard, it justifies the urgent need for research in the field of written speech of ethnic groups living in the territory of the Russian Federation, with the aim of obtaining forensically significant information about the ethnic group of the author of an anonymous text. In conclusion, the author mentions that the determination of the ethnicity of the author is one of the tasks for establishing the demographic characteristics of the author

The Effect Of Fatigue And Sleepiness Upon Driver Behaviors
Authors: BAŞ Fatih İrfan , GÖKDAĞ Mahir
Published: August 2019

Human factor has appeared as the most important factor in traffic
accidents.  It has statistically been
revealed that the rate of defect in death and injuries of drivers, passengers
and pedestrians has reached up to 99%. This has necessitated the analysis of
human behaviors in traffic accidents as driver, pedestrian and passengers.

In this study, the effect
of fatigue and sleeplessness upon behaviors of drivers was investigated. Even
driving and resting periods’ being determined with legal regulations could not
provide drivers to display adequate level of sensitivity. And this caused
drivers to drive until service points or their destination, and therefore the
possibility of their being involved in an accident due to sleeplessness and
fatigue increased. Suggestions were offered to prevent and decrease these
considering the fatal results of traffic accidents.
AUDIENCE CULTURE IN THE RECEPTION OF TEXT: BLACK CAMPAIGNS ON ONLINE MEDIA DURING INDONESIA'S 2014 AND 2019 PRESIDENTIAL ELECTIONS
Authors: Abdullah Irwan , Wahyono Sugeng Bayu , Persadha Pratama Dahlian
Published: August 2019

Purpose of the study: This study seeks to explore the influence of culture on audiences' responses to online negative campaigns during Indonesia's 2014 and 2019 presidential elections. It shows that voter behavior is not determined entirely by media messages, as voters' decisions are strongly informed by their cultural and family backgrounds.

Methodology: Negative campaign messages conveyed through online mass-media coverage were used as the main object of this study. These messages were analyzed categorically, with a focus on their themes, values, and ideologies. Data inference was made contextually, with a specific focus on cultural context.

 Main Findings: Mass media audiences' reception of negative campaigns is not homogenous, but influenced by political ideologies, social statuses, cultures, past experiences, and family characteristics. As such, negative campaigns do not influence the perceptions of mass media audiences, but rather reinforces audiences' existing political preferences. This is because Indonesian audiences are not individual (as common among new media audiences), but rather collective. They are divided into specific groups based on their political ideologies and the socio-cultural values that they learn from their families.

Applications of this study: The findings can be applied to evaluate the media's effectiveness in constructing public knowledge and shaping public decisions.

Novelty/Originality of this study: Although it has long been argued that the media can shape public opinions and decisions, this study shows that it plays a significant role in reinforcing existing political preferences. Audiences use the media to justify values that, owing to their specific family backgrounds and social environments, they have already embraced.

Não falta o que abordar em torno dos diferentes aspectos e questões que respeitam ao financiamento e ao gasto público na prestação de serviços públicos essenciais – como educação, saúde e segurança –, ou à concessão de benefícios – como os de previdência, assistência e proteção ao trabalhador. Apesar disso, em uma economia emergente, na qual seus governos gastam com o serviço de sua dívida um volume de recursos igual ou superior ao que se despende com muitos dos gastos sociais antes mencionados, nunca é demais conhecer e refletir sobre o citado endividamento governamental.Voltando recentemente à berlinda no debate econômico brasileiro, a dívida pública teria saltado, no diagnóstico da situação atual, para seu ponto mais alto na história do Real.

Due to the continued research into chemistry, biology, pharmaceutics and rocket space technology, interest in the study of the dynamics of layered fluids has increased significantly. The paper focuses on oscillations of a three-layer viscous fluid, gives the formulation of the viscous fluid free oscillations problem. Within the research, we determined natural frequencies and damping coefficients of oscillations of the three-layer viscous fluid in a cylindrical vessel by means of the boundary layer method and a mechanical analog. Oscillations of the three-layer viscous fluid were considered as joint oscillations of two partial hydrodynamic systems, one of which corresponds to oscillations of the upper and middle viscous fluids, and the other one - to oscillations of the middle and lower fluids. Then, we determined the coefficients of viscous resistance in partial hydrodynamic systems of a two-layer viscous fluid. Using the mechanical analog of oscillations of the three-layer liquid, we derived the characteristic equation for determining natural frequencies of the hydrodynamic system under consideration. Next, we calculated the dependency of natural frequencies and liquid-liquid interface damping coefficients on the height of the middle layer and the density of the upper fluid. Finally, we analyzed and compared theoretical calculations with the results obtained by other researchers and experimental investigation. The paper gives the results of experimental studies of oscillations of the three-layer fluid in a stationary cylindrical tank.

Separated flows are widespread in many areas of science and technology, such as space technology, aviation, gas turbines, etc., which has a significant effect on the processes of hydrodynamics and heat transfer in them. The separation of the flow and its reattachment can serve as a powerful means of enhancing heat and mass transfer processes, and its organization is quite simple and reliable in terms of technology. This paper presents the results of the experimental study on hydrodynamics and heat transfer in the separation zone in front and behind a single rectangular perforated rib located on a flat plate heated by the law of qw = const. Experimental measurements were carried out using the Pitot-Prandtl tube and Dantec Dynamics hot-wire anemometry system, which allows us to obtain new characteristics of the turbulent boundary layer, both mean and oscillatory ones. We analyzed the influence of the perforation ratio of the rib and the location of the holes in the rib on the heat transfer efficiency. It was established that the stagnant and recirculation zones in front and behind the perforated rib were shifted and became smaller or disappeared. Findings of research show that jet flows, impinging on the heat transfer surface from the perforation holes, provide more efficient heat transfer behind the perforated rib, compared to that behind the solid rib.

The paper focuses on the main components of the logistics planning process and justifies the connection between the qualitative planning of the required number of units and the availability factor of aircraft. We consider the potential of simulation modeling as applied to the study of the complex systems behavior, and substantiate the application of such modeling in the inventory planning and control system for the operation of state aircraft. It was found that the availability factor, the health coefficient and the cost of purchasing spare parts can serve as efficiency criteria. The increased aircraft availability or serviceability is achieved by minimizing downtime due to the lack of spare parts. In our research we describe the simulation model of inventory stock usage and test the model for aircraft operating as part of an aviation regiment. The simulation model showed almost complete coincidence with the results of an analytical model of a queuing system. This means that when planning material and technical support, on the basis of this simulation model, it is possible to build more complex models for analyzing multi-inventory stocks without applying a complex mathematical apparatus. The model can be used as a tool for planning the required number of units for the operation of state aircraft.
Restoration of target work in automatic failure- and fault-tolerant multitasking distributed information-control system

Published: August 2019

The paper deals with the organization of target work recovery processes after admissible failures and faults in an automatic failure and fault tolerant multitask distributed multi-machine system of the network structure performing a set of the target functions set by external users. The system is characterized by parallel execution of a set of interacting target tasks performed on separate computer subsystems, which are organized sets of digital computers. The specified level of failure- and fault-tolerance of the task is provided by its replication, i.e. parallel execution of copies of this task on several computers that make up the system, with the exchange of results and the choice of the correct one.
The study introduces the characteristics, principles of construction, features of the considered systems and their "philosophical" essence from the point of view of failure- and fault-tolerance. Within the research, we determined the factors of complexity in the design of failure- and fault-tolerant systems of this class. The most general model of malicious computer failure is adopted, in which the computer behavior can be arbitrary, different in relation to other computers interacting with it, and even as malicious. We focus on the part of the problem of organizing dynamic redundancy in the developed system. The problem arises after an acceptable set of faults is detected in this system in some complex (or some set of F complexes) by each of the fault-free digital computers of each such complex and each such fault is also synchronously and consistently identified by place of origin and by type as a software failure of a certain digital computer of this complex. This part of the problem is solved by restoring all necessary information identified in a state of software malfunction of a certain complex. The information is transmitted to this digital computer from fault-free digital computers of this complex. The list of instructions required for such a recovery, as well as the actions of the complex in the recovery process, is determined.
