Characterizing Sleep Spindles in Sheep
Authors: Schneider Will T. , Vas Szilvia , Nicol Alister U. , Morton A. Jennifer
Published: March 2020

Sleep spindles are distinctive transient patterns of brain activity that typically occur during non-rapid eye movement (NREM) sleep in humans and other mammals. Thought to be important for the consolidation of learning, they may also be useful for indicating the progression of aging and neurodegenerative diseases. The aim of this study was to characterize sleep spindles in sheep (Ovis aries). We recorded electroencephalographs wirelessly from six sheep over a continuous period containing 2 nights and a day. We detected and characterized spindles using an automated algorithm. We found that sheep sleep spindles fell within the classical range seen in humans (10–16 Hz), but we did not see a further separation into fast and slow bands. Spindles were detected predominantly during NREM sleep. Spindle characteristics (frequency, duration, density, topography) varied between individuals, but were similar within individuals between nights. Spindles that occurred during NREM sleep in daytime were indistinguishable from those found during NREM sleep at night. Surprisingly, we also detected numerous spindle-like events during unequivocal periods of wake during the day. These events were mainly local (detected at single sites), and their characteristics differed from spindles detected during sleep. These “wake spindles” are likely to be events that are commonly categorized as “spontaneous alpha activity” during wake. We speculate that wake and sleep spindles are generated via different mechanisms, and that wake spindles play a role in cognitive processes that occur during the daytime.

Published: March 2020

The article is devoted to the problem of checkability of the circuits as an essential element in ensuring the functional safety of informational and control safety-related systems that monitoring objects of increased risk in the energy, transport, military, space and other industries to prevent accidents and reduce their consequences occurrence.The key role of checkabilityin the transformation of fault-tolerant structures used in such systems into fail-safe ones is noted. The problems of logical checkabilityare shown, including the problem of hidden faults, inherent for safety-related systems in the modern design of its components using matrix structures. It was proposed to supplement logical checkabilitywith other forms, among which the most promising are power-oriented checkability, supported by the successful development of green technologies in FPGA (Field Programmable Gate Array) design. The problems of limited accuracy in the assessment and measurement of temperature, which manifested themselves in the development of thermal testability and thermal methods for monitoring circuits, are noted. The lower and upper power-oriented checkability of the circuits is determined by the current consumption parameter. Analytical estimates of the lower and upper checkability of the circuits by current consumption were obtained considering the peculiarities of their design on FPGA using modern CAD (Computer-Aided Design) using the example of Quartus Prime Lite 18.1. The threshold values of consumption currents in the methods of monitoring circuits for detecting faults in the chains of common signals and short-circuit faults within the framework of the lower and upper checkability are estimated, respectively. Experiments have been performed, to evaluate the lower and upper power-oriented checkability of the circuits and threshold values for the presented monitoring methods, using the example of a scalable circuit of the shifting register, designed for FPGA. The dependences of the power-oriented lower and upper checkability of the circuits on the occupancy of the FPGA chip are shown.
PROOF-OF-GREED APPROACH IN THE NXT CONSENSUS

Published: March 2020

A fundamental problem in distributed computing systems is to make the same decision on an issue. The consensus protocol de-scribes a process to agree on some data value that is needed during computation. The work is devoted to development of the consen-sus algorithm based on the Nxt consensus protocol which can be implemented to blockchain systems with PoS (Proof-of-Stake). PoS consensuses based on node balances, and unlike PoW (Proof-of-Work) methods, are environmentally friendly and more energy effi-cient. Nowadays such types of consensuses are getting more popular. However, they remain less scrutinized than PoW. Moreover, there are some attacks and threats that cannot be completely resolved under PoS consensuses, and in particular under the Nxt.In this article we propose a modification of the Nxt protocol which solves some problems of PoS in accordance with modern requirements. The asymmetric method was used to select the best Nxt consensus parameters for decreasing of the blocktime variance. This im-proves theperformance and reliability of the entire blockchain system eliminating the risk of disruptions due to overflowing the transaction pool. For the Nxt consensus protocol researching, the mathematical simulating model was developed using Anylogic 8.4 software. Implementation of economic leverages (tokenomics), which we called Proof-of-Greed approach, allows to prevent some types of attacks, e.g. large stake attack, and to set a fair market-based transaction fee. The using of economic mechanisms to protect distributed systems allows to prevent a number of attacks that are resistant to cryptographic methods. But at the same time, theto-kenomics of the system should be strictly consistent with the protocols for the functioning of all system objects, combining them into an integrated unitary ecosystem. Also, a payback period of harvesters was investigated within Proof-of-Greed protocol. The parame-ters of such approach for sustained operation of a network were obtained as a result of mathematical simulating with Anylogic 8.4 software. The Proof-of-Greed approach can be implemented not only in the Nxt consensus but in some other blockchain systems based on PoS consensuses.

Published: March 2020

The work is devoted to the development of a control system for a wind generator with the use of a switched reluctance motor. The search for new structures for the construction of the power unit and control system of electromechanical systems of wind power complexes is an urgent task of today. The most common construction options for such systems include double-fed induction motors and permanent magnet synchronous generators. In the first case there is no possibility of full control of the flow of power transmitted to the network, and in the second case the main disadvantage is the high cost of such an electric machine, which is explained by the use of rare earth materials in its design. The use of a switched reluctance motor as a generator has significant differences compared to similar use of electric machines based on torque generation due to the Lorentz force. A mathematical model of the electromechanical system of a wind generator with a switched reluctance motor in the Matlab / Simulink environment was developed. It was shown by mathematical modeling that when changing the sign of load torque, the machine does not go into braking mode independently, as is the case with other electric machines. This creates considerable difficulties in the operation of such a system, since the transition to brake mode requires a change in control effects on the switched reluctance motor. Features of functioning of the switched reluctance motor in the mode of regenerative braking have been stated. The limits of change of control angles which allow to receive the maximum amount of the generated electric energy and reduction of pulsations of brake torque of the machine have been defined. The structure of the control system of a switched reluctance motor has been developed, which involves the use of a modified speed controller, which divides its output signal into a sign function, which is subsequently used to select the converter control angles, as well as the absolute value used in the operation of the modulation algorithm of the required current magnitude.

Abstract

Live traps usually can only trap rats in the first day of trapping because the bait become not luring anymore after the first day of trapping. The purpose of this study was to determine the  differences in lured rats number between uncombined bait trapping and combined bait trapping.

This is a quasi-experimental study with a post-test only non-equivalent control group design. Each house has 5 traps setup with 6 replications. One trap was set with combined bait types (rice, anchovy, tofu and roasted coconut) and four other traps set with separated uncombined bait types; (1) rice, (2) anchovy, (3) tofu, (4) roasted coconut. The instruments used were house screening sheets, traps and observation sheets. The data obtained were tested with the Mann-Whitney test.

The results showed that there were not significant differences in trapped rats number between combined bait and uncombined rice bait (p=0.748), between combined bait and uncombined anchovy bait (p=0.355), between combined bait and uncombined tofu bait (p=1.000), and also between combined bait and uncombined roasted coconut bait (p=0.734). Uncombined anchovies bait trapped rats most. Combined bait and uncombined anchovy bait were most consistent in trapping rats.

This study aimed to investigate the correlation between social anxiety and self-esteem among the special need university students from Peshawar city, Khyber Pakhtunkhwa, Pakistan. The sample size was comprised of 100 disable university students aged 18-30 years, out of which 50 were male and 50 were female. A correlational study was designed. The social anxiety levels of the recruited subjects were determined through Liebowitz Social Anxiety Scale. The level of self-esteem was determined through the standard self-report mechanism by applying the Rosenberg Self-esteem Scale. The data collected were tabulated, analyzed and interpreted through SPSS software, Version 23, for windows, by using means, percentages, Pearson’s product-moment correlation coefficient (r) and Independent sample t-test.  On average, the students with high social anxiety and low levels of self-esteem were found (r = -620), social anxiety of female students was high (M=78.14, SD=14.67) as compared to male students (M=59.34, SD=14.41). However, the self-esteem of female students (M=16.08, SD=1.77) was the same as compared with male students (M=16.38, SD= 1.86). There was a significant negative relationship found between social anxiety and self-esteem. The social anxiety of female disable university students was high, however, the male and female disable university students have the same self-esteem.

Impact of the Revised NRP Meconium Aspiration Guidelines on Term Infant Outcomes
Authors: Myers Patrick , Gupta Arika G.
Published: March 2020

OBJECTIVES:

To evaluate the association of the Neonatal Resuscitation Program, Seventh Edition changes on term infants born with meconium-stained amniotic fluid (MSAF).

STUDY DESIGN:

We evaluated the effect of no longer routinely intubating nonvigorous term infants born with MSAF in 14 322 infants seen by the resuscitation team from January 1, 2014 to June 30, 2017 in a large, urban, academic hospital.

RESULTS:

Delivery room intubations of term infants with MSAF fell from 19% to 3% after the change in guidelines (P = <.0001). The rate of all other delivery room intubations also decreased by 3%. After the implementation of the Seventh Edition guidelines, 1-minute Apgar scores were significantly more likely to be >3 (P = .009) and significantly less likely to be <7 (P = .011). The need for continued respiratory support after the first day of life also decreased. Admission rates to the NICU, length of stay, and the need for respiratory support on admission were unchanged.

CONCLUSIONS:

Implementation of the Neonatal Resuscitation Program, Seventh Edition recommendations against routine suctioning nonvigorous infants born with MSAF was temporally associated with an improvement in 1-minute Apgar scores and decreased the need for respiratory support after the first day of life. There was also a significant decrease in total intubations performed in the delivery room. This has long-term implications on intubation experience among frontline providers.
Parent Perspectives During Hospital Readmissions for Children With Medical Complexity: A Qualitative Study
Authors: Leary Jana C. , Krcmar Rachel , Yoon Grace H. , Freund Karen M. , LeClair Amy M.
Published: March 2020

OBJECTIVES:

Children with medical complexity (CMC) have high readmission rates, but relatively little is known from the parent perspective regarding care experiences surrounding and factors contributing to readmissions. We aimed to elicit parent perspectives on circumstances surrounding 30-day readmissions for CMC.

METHODS:

We conducted 20 semistructured interviews with parents of CMC experiencing an unplanned 30-day readmission at 1 academic medical center between December 2016 and January 2018, asking about topics such as previous discharge experiences, medical services and resources, and home environment and social support. Interviews were recorded, professionally transcribed, and analyzed thematically by using a modified grounded theory approach.

RESULTS:

Children ranged in age from 0 to 15 years, with neurologic complex chronic conditions being predominant (35%). Although the majority of parents did not identify any factors that they perceived to have contributed to readmission, themes emerged regarding challenges associated with chronicity of care and transitions of care that might influence readmissions, including frequency of hospital use, symptom confusion, lack of inpatient continuity, resources needed but not received, and difficulty filling prescriptions.

CONCLUSIONS:

Parents identified multiple challenges associated with chronicity of medical management and transitions of care for CMC. Future interventions aiming to improve continuity and communication between admissions, ensure that home services are provided when applicable and prescriptions are filled, and provide comprehensive support for families in both the short- and long-term may help improve patient and family experiences while potentially decreasing readmissions.

OBJECTIVES:

To assess the relationship between vaccination status and clinician adherence to quality measures for children with acute respiratory tract illnesses.

METHODS:

We conducted a multicenter prospective cohort study of children aged 0 to 16 years who presented with 1 of 4 acute respiratory tract illness diagnoses (community-acquired pneumonia, croup, asthma, and bronchiolitis) between July 2014 and June 2016. The predictor variable was provider-documented up-to-date (UTD) vaccination status. Our primary outcome was clinician adherence to quality measures by using the validated Pediatric Respiratory Illness Measurement System (PRIMES). Across all conditions, we examined overall PRIMES composite scores and overuse (including indicators for care that should not be provided, eg, C-reactive protein testing in community-acquired pneumonia) and underuse (including indicators for care that should be provided, eg, dexamethasone in croup) composite subscores. We examined differences in length of stay, costs, and readmissions by vaccination status using adjusted linear and logistic regression models.

RESULTS:

Of the 2302 participants included in the analysis, 92% were documented as UTD. The adjusted mean difference in overall PRIMES scores by UTD status was not significant (adjusted mean difference −0.3; 95% confidence interval: −1.9 to 1.3), whereas the adjusted mean difference was significant for both overuse (−4.6; 95% confidence interval: −7.5 to −1.6) and underuse (2.8; 95% confidence interval: 0.9 to 4.8) composite subscores. There were no significant adjusted differences in mean length of stay, cost, and readmissions by vaccination status.

CONCLUSIONS:

We identified lower adherence to overuse quality indicators and higher adherence to underuse quality indicators for children not UTD, which suggests that clinicians “do more” for hospitalized children who are not UTD.
PATHOMORPHOLOGICAL ASPECTS OF RELEVANT GASTROINTESTINAL DISEASES IN NEWBORN AND GROWING CALVES
Authors: Kalkanov I. , Dinev Iv.
Published: March 2020

The emphasis of this literature overview is placed on the etiology, epidemiology, specific gross and microscopic pathological changes of the commonest gastrointestinal diseases in newborn and growing calves in dairy and beef farms. Neonatal diarrhea in calves is a multifactorial disease accompanied with high morbidity and mortality rates. It incurs considerable economic losses for cattle industry worldwide. The gastroenteritis in calves is most commonly of infectious or parasitic etiology and the most frequently involved enteropathogens are Cryptosporidium parvum, bovine rotaviruses (GRA BRV), bovine coronaviruses (BCoV), mucosal disease virus - bovine viral diarrhoea (BVDV) and Escherichia coli K99 (F5). Affected calves are from 24th hours to 30 days of age, and the appearance of the disease is largely dependent on the immunological status of newborn calves, the amount of ingested colostrum, whether dams are vaccinated or not during the dry period, and the conditions of housing of newborns.
The specific gross and microscopic lesions of the gastrointestinal tract and of some parenchymal organs are essential for the diagnostics and differential diagnostics of reviewed diseases.
Apocheiridium ferum (Simon, 1879) (Arachnida, Pseudoscorpiones, Cheiridiidae), a newly recorded genus and species of pseudoscorpion for Hungary
Authors: Christophoryová Jana , Červená Martina
Published: March 2020

The genus Apocheiridium Chamberlin, 1924 is reported from Hungary for the first time. Adults of Apocheiridium ferum (Simon, 1879) were collected under the bark of a Platanus Linné, 1753 tree in Pápa, Veszprém County. Simultaneously, the second known European cheiridiid species, Cheiridium museorum (Leach, 1817), was found under the same bark. The differences between these two species are discussed. With the new record of A. ferum, 54 species and 21 genera are now known for the Hungarian fauna of Pseudoscorpiones.

What material and media are used in each Khitobah activity. To discuss the issue, researchers used a descriptive method of qualitative approach. This method is used to explain and tell. The facts that happened the Khitobah activity by Rohis Baitul Ilmi in SMK 1 Cikampek. The data collection technique is carried out through the observation and interview stages. The results of this study are the Rohis communication model at SMK 1 Cikampek which is the Aristotelian communication model and the Laswell communication model. Because in some circumcision activities carried out Rohis has the same communication elements as the elements of the communication model. While the form of Khitobah used is by way of Ershad Islam (coaching) conveying its message through verbal preaching. The media used in delivering da'wah messages is Facebook, Instagram, and YouTube. The material was delivered in accordance with the objectives of da'wah, which is around adolescents originating from Al-Qur'an and As-Sunnah.

 

Tujuan penelitian ini untuk mengetahui model komunikasi yang digunakan oleh Rohis Baitul Ilmi SMKN 1 Cikampek, mengetahui bagaimana kegiatan yang dilakukan oleh Rohis Baitul Ilmi SMKN 1 Cikampek.

Authors: Glushkov Alexander , Ternovsky Valentin , Prepelitsa Georgy
Published: March 2020

In the paper we present development of a new relativistic chaos-geometric and quantum-dynamic approach to solve problems of complete modelling relativistic chaotic dynamics of atoms in an electromagnetic field. As usually the approach consistently includes a number of new relativistic quantum models and a number of new or improved methods of analysis (correlation integral, fractal analysis, algorithms, average mutual information, false nearest neighbors, Lyapunov exponents, surrogate data, non-linear prediction, spectral methods, etc.) For  the first time we present   the corresponding atomic ionization quantitative data for some atoms in a microwave external field.

Intensive Consulting for Schools by Mitigating the Impact of Social, Economic and Cultural Context on Students’ Learning Achievements
Authors: Bruzgelevičienė Ramutė
Published: March 2020

The article analyses the question, how intensive consulting for schools can affect students’ learning achievements by mitigating the impact of social, economic and cultural context. Based on the case study methodological approach, the case of the project “Initiative for municipalities”, implemented in 2016–2018 in five schools of Kupiškis district municipality, was analysed. After conducting the analysis of the theoretical literature and documentary sources, and interviews, the following conclusions were made:Due to its duration and intensity, it was long-term consulting; mixed – expert and procedural – consulting approaches were used depending on the problems raised in the schools, the context, readiness of the teachers for change, and the nature of changes proposed by the consultant. It is recognized that the characteristics of the expert consulting dominated.The intensive long-term consulting, implemented in schools resulted in improvement of students’ achievements due to intentionally selected consulting targets – guiding of schools and teachers towards change in the school culture, orientation towards strengthening teaching/ learning assistance, and the application of teaching/learning strategies favourable to students. The consultant’s attempt to implement the teaching methodology based on post-cognitive principles in schools is discussed. The issues discussed remain open for further research.

Archbishop Mečislovas Reinys is one of the most prominent personalities. He paid much attention to personality development. According to him, multidisciplinary education is very important, where a person’s personality can unfold. The Archbishop was admired by Don Bosco’s ideas to make the school a community. This is important nowadays when the school’s threshold goes beyond personality with a variety of life experiences. Consequently, it must appear as one of the most important factors in education, to be a moral and valuable core, which is not differ from life. Therefore, it is right to call today‘s Catholic school a cross of experience and ideas. The ideas of Archbishop Mečislovas Reinys about education and upbringing have not lost their persistence. They find a proper response to the activities and mission of the current Catholic schools.
