Properties of solid hydrogen doped by heavy atomic and molecular impurities

Using powder x-ray diffraction we studied the structural characteristics of normal and para hydrogen crystals doped with Ar, Kr, N₂, and O₂ impurities over the range from 5 K to the melting point of the hydrogen matrix. It has been established that in spite of very low solubility of the dopants in solid hydrogen, these impurities appreciably affect the structural characteristics. In particular, only nitrogen impurities do not change the molar volume of the matrix, the other three make the matrix expand. The Ar and Kr impurities also change the c/a ratio of the hcp matrix. The fact that both Ar and O₂ have smaller molar volumes than hydrogen may be treated as evidence that these impurities form van der Waals complexes with the hydrogen lattice environment

Scheduling real-time tasks in mobile devices

Спроектирован и разработан диспетчер задач реального масштаба времени для мобильных устройств, работающих на базе операционной системы Android. Исследованы особенности планирования задач, подлежащих выполнению на современных мобильных устройствах. Отмечено, что в настоящее время для диспетчеризации задач чаще всего применяются скалярные критерии, приводящие к задержкам в работе мобильных устройств, вызванных конфликтами, возникающими при использовании общих ресурсов. Использованный в диспетчере алгоритм планирования задач по структурному критерию, предложенный авторами, обеспечивает функционирование в многозадачном режиме до 64-х задач с учетом важности каждой задачи, времени первого запуска и/или периода повторения задачи и другими характеристиками, которые назначаются индивидуально для каждой задачи.Спроектований та розроблений диспетчер задач реального виміру часу для мобільних пристроїв, працюючих на базі операційної системи Android.

Were analyzed the features of scheduling tasks to be performed on modern mobile devices. It is noted that at the present time for scheduling tasks often scalar criteria are applied, leading to delays in the work of mobile devices, due to the conflicts that arise when using shared resources. Used in Task Scheduler scheduling algorithm on structural criteria proposed by the authors, it operates multitask up to 64 tasks, taking into account the importance of each task, the time of the first startup and / or the repetition period of the tasks and other characteristics that are assigned individually for each task

Using software support for quantum superposition effects to speed up the solution of the targeted enumeration issue in biometric data when extracting knowledge from a neural network

Background. The continuum/discrete processing of information by natural neurons and artificial neurons is considered. The purpose of the work is to demonstrate the possibilities of unlimitedly long-term support of the effects of quantum superposition by artificial neurons. Materials and methods. As an example, a network of 256 artificial binary neurons (perceptrons) is used. When simplifying the computational complexity of entropy estimates, the state standard GOST R 52633.3–2011 is used. When duplicating data, GOST R 52633.2–2010 is used. The inversion of matrices of neural network functionals with dimensions of 416×256 is performed iteratively according to the criterion of reducing the entropy of the output codes of the neural network. Results and conclusions. It is shown that the support of the effects of quantum superposition with a duration of about 20 minutes on a conventional computer makes it possible to solve the inverse problem of neural network biometrics. It is possible to extract knowledge from the neural network with a confidence probability of 0.97 about the cryptographic key of the user “Svoy” and about the parameters of the biometric image of the user “Svoy”

SCHEMES FOR THE ERADICATION OF HELICOBACTER PYLORI STRAINS RESISTANT TO METRONIDAZOLE AMONG CHILDREN

Treatment of the gastroenterological diseases associated with the helicobacterial infection is a complex issue. This is due to the new strains of microorganisms resistant to the medications applied. Based on the data acquired during the examination of 30 children, they showed the high efficacy of the scheme for the triple eradication therapy against helicobacteriosis, which included nifuroxazide suspension (enterofuril) along with omeprazole and clarithromycin. The authors also substantiated the expediency to prolong the treatment up to 10–14 days to improve the eradication efficacy.Key words: children, helicobacter pylori, nifuroxazide, treatment
