Published: January 2021

Явление структурной наследственности получило промышленное применение, несмотря на то что «механизм передачи наследственных признаков расплаву, их сохранение, зарождение в нем новых признаков и передача их твердому металлу - все это сложные, во многом неизученные вопросы» (Б.А. Баум с коллегами). На примерах стали, чугуна и алюминия предпринята попытка обоснования предположения, что одним из механизмов передачи наследственных признаков может быть эффект «памяти жидкости», который заключается в сохранении ее свойств при очень сильном разбавлении.

The phenomenon of structural heredity is used by industry, although «the mechanism of transmission of hereditary traits to the melt, their conservation, the generation of new traits in it and their transfer to solid metal are all complex, largely unexplored issues» (B.A. Baum with colleagues). On the examples of steel, cast iron and aluminum, an attempt was made to substantiate the assumption that one of the mechanisms of transmission of hereditary traits could be the effect of «fluid memory», which consists in maintaining its properties with very strong dilution.

Stochastic hydrology: the development of main ideas in Russia
Authors:   Institute of Water Problems RAS, Bolgov Mikhail V.
Published: January 2021

The aim of the work is to assess the current state of scientific research and the main results in the field of stochastic hydrology. Various problems of scientific and applied hydrology are solved on the basis of different types of stochastic models. On the basis of these models, methods are being developed for obtaining secure engineering runoff characteristics, or reliable hydrological forecasts of various lead times. Most of the water management, construction, environmental and other problems are solved today within the framework of probabilistic models and statistical methods. The main tasks of stochastic hydrology can be divided into several groups. Despite the discussion in hydrology on the applicability of the theory of probability and random processes to the analysis of fluctuations of hydrometeorological series, the problem of choosing a research methodology remains one of the most important, and is often discussed in connection with anomalous manifestations of hydrological phenomena (extreme floods, prolonged droughts). An important applied and theoretical problem in hydrology is the choice of a one-dimensional probability distribution. In this part, discussions are important both on the problem of the type of new distributions and on methods for estimating parameters. Ideas and hypotheses are considered that can significantly increase the reliability of statistical characteristics. Climatic changes in many cases cause disturbances in the stationarity of time series of hydrological characteristics. Progress in the development of new approaches to probabilistic modeling is associated both with the well-known problem of the sufficiency of the Markov hypothesis and with the need to introduce new, more complex models and Bayesian estimation methods. The article is devoted to the discussion of the current state of these problems in the form of a scientific review.
On the relation of bottom valley-type reservoir hydrocarbon carbon flux and hydrological structure of water body

Circulation of carbon in water bodies is fundamental process of nutriens cycle in water ecosystems. Carbon flux from bottom sediments is the less studied chain of this circulation nowdays. The aim of investigation was the study of HCO3 flux from bottom sediments in the valley-type reservoir and identification of their relation with hydrological structure of water body. Field works and laboratory experiments were fulfilled at Mozhaisk reservoir in 2017-2019. These years differed by weather conditions, level regime and stability of water masses. Hydrological surveys were fulfilled three times during summer period of each year. They included measuring of vertical distribution of hydrological characteristic and sampling of water and bottom sediments. The Kuznetsov-Romanenko tube method was used to study exchange processes. Hydrocarbonate carbon flux from sediments into the water may have a wide range (50-900 mgC/m2day). By comparison of HCO3 flux with hydrological structure it was revealed that in deep (>8 m) regions it depends on stratification and thickness of uniform hypolymnion, where seiches and compensation currents may promote transsedimentation from shallow places to flooded river bed. At the regions with depth <8 m hydrocarbonate carbon flux from sediments depends much more from autochthonic organic matter, produced by phytoplankton. The relationship of the HCO3 flux with the content of organic matter in the soil and its hygroscopic humidity is insignificant.

Plastid Transcriptomics: An Important Tool For Plastid Functional Genomics
Authors: Ahmad Niaz , Nielsen Brent L.
Published: January 2021

Plastids in higher plants carry out specialized roles such as photosynthesis, nitrogen assimilation,
biosynthesis of amino acids, fatty acids, isoprenoids, and various metabolites. Plastids
arise from undifferentiated precursors known as proplastids, which are found in the root and shoot
meristems. They are highly dynamic as they change their number, morphology, and physiology according
to the tissue they are present. In addition to housing various metabolic activities, plastids also
serve as a global sensor for both internal and external environmental cues including different
stresses, and help plants to respond/adjust accordingly. They relay information to the nucleus,
which then responds by changing the expression levels of specific genes. It has been shown that
plants with impaired plastid functions exhibit abnormalities. One of the sources emanating these
signals to the nucleus is plastid transcription. Normal plastid functioning is therefore critical for
plant survival. Despite immense significance for plant acclimation, the plastid transcriptome is
largely an unstudied research area. In this review, we discuss the importance of plastid transcriptomics
for the acclimation of plants under changing environmental conditions and summarize the
key literature published in this field.
Application of Two New Feature Fusion Networks to Improve Real-time Prostate Capsula Detection
Authors: Wu Shixiao , Guo Chengcheng , Wang Xinghuan
Published: January 2021

Background:

Excess prostate tissue is trimmed near the prostate capsula boundary during
transurethral plasma kinetic enucleation of prostate (PKEP) and transurethral bipolar plasmakinetic
resection of prostate (PKRP) surgeries. If a large portion of the tissue is removed, a prostate
capsula perforation can potentially occur. As such, real-time accurate prostate capsula (PC) detection
is critical for the prevention of these perforations.

Objective:

This study investigated the potential for using image denoising, image dimension reduction
and feature fusion to improve real-time prostate capsula detection with two objectives. First,
this paper mainly studied feature selection and input dimension reduction. Secondly, image denoising
was evaluated, as it is of paramount importance to transient stability assessment based on neural
networks.

Methods:

Two new feature fusion techniques, maxpooling bilinear interpolation single-shot multibox
detector (PBSSD) and bilinear interpolation single shot multibox detector (BSSD) were proposed.
Before original images were sent to the neural network, they were processed by principal
component analysis (PCA) and adaptive median filter (AMF) for dimension reduction and image
denoising.

Results:

The results showed that the application of PCA and AMF with PBSSD increased the
mean average precision (mAP) for prostate capsula images by 8.55% and reached 80.15%, compared
with single shot multibox detector (SSD) alone. Application of PCA with BSSD increased
the mAP for prostate capsula images by 4.6% compared with SSD alone.

Conclusion:

Compared with other methods, ours were proven to be more accurate for real-time
prostate capsula detection. The improved mAP results suggest that the proposed approaches are
powerful tools for improving SSD networks.

The aim of this study was to investigate the effects of the number of visual hints accompanying the educational content in the interactive video clips on the achievement of some learning outcomes among students of the second intermediate grade in the Ha’il region. Sixty students participated in this study and were divided into three groups and studied according to three scenarios, respectively, interactive videos without a hint, visual hints with color, visual hints with color and arrows. The results showed that a group that studied by color and hint got more results and improvements than a group that studied without a hint and visual hint with color and arrows group. This study recommended the necessity of working on the design and use of interactive video clips based on the use of visual hints in different courses, working on training teachers on how to use videos and employing them correctly, and working on conducting more research studies on the effectiveness and impact of using visual hints accompanying the interactive videos in teaching other courses.
The Impact of Electronic Health Record–Based Simulation During Intern Boot Camp: Interventional Study

Published: January 2021

Background

Accurate data retrieval is an essential part of patient care in the intensive care unit (ICU). The electronic health record (EHR) is the primary method for data storage and data review. We previously reported that residents participating in EHR-based simulations have varied and nonstandard approaches to finding data in the ICU, with subsequent errors in recognizing patient safety issues. We hypothesized that a novel EHR simulation-based training exercise would decrease EHR use variability among intervention interns, irrespective of prior EHR experience.

Objective

This study aims to understand the impact of a novel, short, high-fidelity, simulation-based EHR learning activity on the intern data gathering workflow and satisfaction.

Methods

A total of 72 internal medicine interns across the 2018 and 2019 academic years underwent a dedicated EHR training session as part of a week-long boot camp early in their training. We collected data on previous EHR and ICU experience for all subjects. Training consisted of 1 hour of guided review of a high-fidelity, simulated ICU patient chart focusing on best navigation practices for data retrieval. Specifically, the activity focused on using high- and low-yield data visualization screens determined by expert consensus. The intervention group interns then had 20 minutes to review a new simulated patient chart before the group review. EHR screen navigation was captured using screen recording software and compared with data from existing ICU residents performing the same task on the same medical charts (N=62). Learners were surveyed immediately and 6 months after the activity to assess satisfaction and preferred EHR screen use.

Results

Participants found the activity useful and enjoyable immediately and after 6 months. Intervention interns used more individual screens than reference residents (18 vs 20; P=.008), but the total number of screens used was the same (35 vs 38; P=.30). Significantly more intervention interns used the 10 most common screens (73% vs 45%; P=.001). Intervention interns used high-yield screens more often and low-yield screens less often than the reference residents, which are persistent on self-report 6 months later.

Conclusions

A short, high-fidelity, simulation-based learning activity focused on provider-specific data gathering was found to be enjoyable and to modify navigation patterns persistently. This suggests that workflow-specific simulation-based EHR training throughout training is of educational benefit to residents.

Metallic nanoparticles (NPs) are being used mainly because they have excellent physical, chemical and biological properties, intrinsic to their size, therefore there is a boom in the use of these nanoparticles in various fields and recently, due to the pandemic about coronavirus. Copper NPs began to be used for use in medical supplies such as face masks. NPs are normally obtained through inorganic synthesis, however, the methodologies used to obtain them are in general terms expensive and involve the use of hazardous chemicals, which has increased the development of sustainable and environmentally friendly alternatives, as one of the main objectives of nanotechnology. Considering that nanoparticle biosynthesis is of greatest importance since it allowed obtaining organic NPs through an environmentally friendly; quick and inexpensive.

In this work, the synthesis and characterization of AuNPs of six different plant extracts that in traditional medicine are used for respiratory diseases care, were performed. These NPs can be used in different fields; even they represent a good option to be added to medical supplies. As the AuNPs obtained from chamomile extract that turned out to be spherical, 20 nm in diameter, and well dispersed, these could be applied orally, as nanocapsules that are easily eliminated from the human body, or by aerosol, as a possible treatment for the pneumonia and SARS-CoV-2, in addition later for other nosocomial diseases. And to answer the question of what or which reducing agents are involved in the process? We proposed that, for biological synthesis, malic acid may be acting as a reducing agent and the amino group as a stabilizing agent, so we performed a synthesis with malic acid and obtained stable NPs. However, we do not dismiss other metabolites enzymes and/or proteins that could be involved in the process.

Los compuestos fenólicos son metabolitos secundarios presentes en una diversidad de material vegetal cuya concentración, en el caso del café se ve afectada durante el proceso de tostado. La investigación tuvo como objetivo determinar el efecto que tiene la temperatura de tostado en la contracción de los compuestos fenólicos totales y actividad antioxidante del café. Se contó con 300 gramos de café verde del cual 150 gramos sufrieron un proceso de tostado medio (195 0C aproximadamente). Se emplearon tres métodos colorimétricos para determinación de fenoles totales, flavonoides. La actividad antioxidante se evaluó por el método del radical libre 2,2-difenil-1-picrilhidrazil (DPPH) y poder reductor férrico (FRAP). Se observó una mayor concentración de fenoles totales y flavonoides en el café verde con diferencia significativa respecto al tostado (p<0,263). En relación a las antocianinas la contracción fue superior en el café tostado (p<0,324). Se observó una actividad antioxidante por el método de DPPH fue de 92,2 % (IC50=298,4 para el extracto de café verde y de 79,3 % para café tostado. Del estudio se concluye que la temperatura repercute en la contracción de los compuestos fenólicos presentes en el café, influyendo en la actividad antioxidante de una de las bebidas más consumidas a nivel mundial.

Homonymous and tautological rhymes in K. Simonov’s poetry
Authors: Korzhova Inessa N. , Ledenev Alexander V.
Published: January 2021

The article explores homonymous and tautological rhymes in K. Simonovs poetry as a form of language game. The study of rhymes in the authors poetry, as well as the appeal to the categories of play-element poetics in connection with his work, is realized for the first time. The term polysemantic rhyme is introduced to denote the transitional case between the two types of rhymes which is often found in Simonovs poetry. The dynamics of rhyme preferences and their functions throughout Simonovs work is revealed. In the early poems, he actively uses homonymous rhymes, that have a characterizing and world-modeling function. Rhyme becomes part of a more complex game and is reinforced by repetitions of similar-root and similar-sounding words, that create a dense semantic grid of important to Simonov concepts. In mature creativity, the poet often turns to polysemantic rhyme, and if he puts homonyms at the end of the line, they does not always rhyme with each other. While maintaining the previous functions, traditional humorous and compositional ones are added to them, the latter is associated with the separation of lines as independent aphorisms.
