Semianalytical Measures of Nonlinearity Based on Tensor Eigenpairs
Authors: Jenson Erica L. , Scheeres Daniel J. 
Published: November 2022

This paper proposes a semianalytical measure of nonlinearity (MoN) based on tensor eigenpairs. Approximating nonlinear dynamics via local linearization is a common practice that is used to enable analytical methods in dynamics, control, navigation, and uncertainty propagation. However, these linear approximations are only applicable near the linearization point, and the size and characteristics of the linear region are dependent on the system’s underlying degree of nonlinearity. This paper presents a novel MoN that is based on the eigenpairs of tensors that are derived from the higher-order terms in a Taylor series expansion, e.g., the local dynamics tensors and state transition tensors. Unlike existing MoN, the tensor eigenpair measure of nonlinearity (TEMoN) is semianalytical and its computation does not require empirical sampling or numerical optimization. TEMoN can be used to quantify nonlinearity, identify directions of strong nonlinearity, predict the size of a linear region, and justify the truncation order of a Taylor series expansion by distinguishing higher-order contributions to nonlinearity. The TEMoN method is demonstrated for equilibrium points in the circular restricted three-body problem, near-rectilinear halo orbits, and nonlinear parameter transformations.
Rozprawa zdalna w postępowaniu przed sądami administracyjnymi, a prawo do jawnego rozpoznania sprawy
Authors: Krzykowski Przemysław , Hrymowicz Karolina 
Published: November 2022

Przedmiotem niniejszej publikacji jest analiza obecnie obowiązujących regulacji ustawy z dnia 2 marca 2020 r. o szczególnych rozwiązaniach związanych z zapobieganiem, przeciwdziałaniem i zwalczaniem COVID-19, innych chorób zakaźnych oraz wywołanych nimi sytuacji kryzysowych (t. j. Dz. U. z 2021 r., poz. 2095 ze zm., dalej: ustawa covidowa) oraz wskazanie na ich niedostatki w kontekście realizacji zasady jawnego rozpatrywania spraw sądowoadministracyjnych.
Z zasad naczelnych postępowania sądowoadministracyjnego wynika, że proces powinien być jawny, a strona powinna mieć prawo dostępu do sądu, kontroli zaskarżonych aktów oraz czynnego w nim udziału. Prawo jednostki do sprawiedliwego i jawnego rozpatrzenia sprawy bez nieuzasadnionej zwłoki, przez właściwy, niezależny, bezstronny i niezawisły sąd, ma wymiar konstytucyjny. Celem zasady jawności jest motywowanie sądu do skrupulatnego i rzetelnego wypełniania obowiązków procesowych oraz umożliwianie osobom postronnym sprawowanie obywatelskiej kontroli nad działalnością sądów. Autorzy w artykule próbują odpowiedzieć na pytanie, czy rozprawa odmiejscowiona w sądach administracyjnych oraz zastępcza jego forma, jaką jest posiedzenie niejawne, spełnia konstytucyjne standardy jawności postępowania. Wartością nieocenioną dla strony jest jej osobisty udział w rozprawie i możliwość swobodnego zaprezentowania swojego stanowiska na sali rozpraw, bezpośrednio przed sądem. To stanowi realizację prawa do aktywnego udziału w postępowaniu. Strony mają wówczas możliwość wypowiedzenia swoich racji, a to przekłada się na poczucie podmiotowego ich traktowania.
Autorzy w konstatacji wskazują, że ustawodawca powinien wprost określić formułę dostępu publiczności do rozprawy zdalnej, ewentualnie zmodyfikować covidowe regulacje w ten sposób, by sąd miał swobodę w ocenie sytuacji pozwalającej lub nie, przeprowadzić rozprawę w budynku sądu. Być może większy wachlarz możliwości pozwoliłby na trafniejsze rozwiązania, które nie naruszałyby zasady jawności postępowania sądowego i nie ograniczałyby obywatelowi prawa do sądu.
The Centrality of Conceptual Metaphor in Second Language Teaching and Learning | Markaziyyah al Isti’aroh Attashowuriyah Fii Ta’lim wa Ta’allum Allughah Atsaniyah
Authors: Jaouhari Ahmed , Syaifullah Muhammad 
Published: November 2022

This researchseeks to prove the pivotalrole of conceptual metaphor - as presented by the cognitive orientation launched by George Lakoffat the beginning of the eighties of the last century - in teaching and learning the second language, and how metaphor contributes to developing the cognitive abilities of learnersat the level of understanding and interpreting the speech of the second language, whetheritis oral or written. In order to clarify the interactions that exist between the metaphorical competence and the communicative competences of the learner, wedecided, since the beginning of this research, to identify some of the issues and hypotheses that metaphor stems from, highlighting the importance of metaphorical awareness in acquiring the target language, by linking the conceptual domain of the first language as a source domain with the conceptual domain of the second language as a target domain. In the context of this transition, we have high lighted the importance of conceptual fluencyas a contrast to linguistic fluence in the teaching and learning of the second language. Linguistic, social, textual, grammatical, strategic, and other educational competencies.

Published: November 2022

Изложены результаты изучения семенной продуктивности кислотоустойчивых образцов клевера лугового F3211 и F3236 с использованием методов биотехнологии. Исследования проводили в условиях селекционно-тепличного комплекса, в камерах искусственного климата. Цель исследований — оценить лабораторными и вегетационными методами показатели семенной продуктивности кислотоустойчивых форм клевера лугового. При оценке in vitro в селективных условиях с различными концентрациями ионов алюминия наибольшую устойчивость показали проростки F3211, у которых в варианте с 50 мг/л Al3+ образовались корни длиннее на 45,2%, чем у проростков F330 (ВИК). Лучшие растения клевера лугового, полученные из устойчивых к ионам алюминия проростков, превышали контрольные растения по числу побегов на 53,6% и соцветий — на 186,3%. При этом токсическое последействие ионов алюминия в большей степени повлияло на образование цветков и семян в соцветиях клевера лугового. Так, у F3211 растений, полученных из проростков в вариантах с 50 и 100 мг/л Al3+, процент цветков и семян в одном соцветии был на 5,4 и 13,6%; 6,7 и 9,3% соответственно ниже по отношению к соответствующему контролю (вода). Отбор in vitro на уровне проростков F3211 и F3236 в селективных условиях повысил показатели семенной продуктивности по сравнению с исходными образцами F2211 и F2236: у F3211 по числу побегов — на 213,3%, числу соцветий — на 131,2%, у F3236 — на 47,4% и 48,5% соответственно. При этом лучшие растения по продуктивности семян с одного растения превышали таковую у F3211 на 115,7%, у F3236 — на 45,3%.
This article reports on seed productivity of acid-resistant genotypes of red clover F3211 and F3236 using biotechnology methods. The investigation took place in climate chambers of a greenhouse complex. The aim was to test seed productivity of acid-resistant red clover under the lab and greenhouse conditions. Experiments in vitro with various concentrations of aluminum ions showed that F3211 germs were the most tolerant. When using 50 mg/l Al3+ they formed 45.2% longer roots than F330 (VIK). The best plants grown from aluminum-resistant germs exceeded the control in shoot number by 53.6%, inflorescence number — by 186.3%. Toxicity of aluminum ions mostly affected flower and seed formation. F3211 plants, treated previously with 50 and 100 mg/l Al3+, produced less flowers and seeds in one inflorescence by 5.4 and 13.6% as well as 6.7 and 9.3%, respectively. In vitro selection of F3211 and F3236 germs resulted in better plant productivity: F3211 exceeded F2211 in shoot number by 213.3%, inflorescence number — by 131.2% while F3236 exceeded F2236 in the same parameters by 47.4% and 48.5%, respectively. The best plants exceeded the productivity per one F3211 plant by 115.7%, F3236 — by 45.3%.

Published: November 2022

Aim. To determine the incidence of premature ovarian failure (POF) and early menopause with regard to reproductive status in carriers of the pathogenic variant of the BRCA1 gene.
Materials and methods. According to the inclusion and exclusion criteria, out of 90 carriers of pathogenic variants of the BRCA1 gene, 38 females were included in the study group, and 110 females without these pathogenic variants were included in the control group. The reproductive status, age of menopause onset, history of pelvic surgeries, and palliative care were evaluated in the study groups.
Results. The incidence of POF in the group of carriers of pathogenic variants of the BRCA1 gene was significantly higher compared to the control group (p0.004), while the incidence of early menopause showed no significant differences in the studied groups (13.2% vs. 4.5%, respectively; p0,069). No significant differences were found in the analysis of reproductive status.
Conclusions. Females with and without pathogenic variants of the BRCA1 gene did not differ significantly by the main indices of reproductive status. Carriers of pathogenic BRCA1 gene variants have a significantly higher incidence of POF vs. controls. Adverse effects of pathogenic BRCA gene variants on women's ovarian reserve and reproductive potential cannot be excluded. Healthy carriers of pathogenic variants of the BRCA1/2 gene are recommended to plan pregnancy in the early reproductive period.

Experimental Study of a Solar Still Desalination System
Authors: Guo Jie , Liu Lin-Sen 
Published: November 2022

Solar still is a simple equipment for the fresh water production in the regions where water is scarce and is rich in solar energy sources. In this paper, a solar still unit was built and tested in the south of China to investigate its water production. The test results show that the fresh water production is affected by average solar irradiation intensity, the production of the unit averaged at 6.27 kg/day, the water production decreased to 1.9 kg/day when the daily average solar radiation decreased to 236 W/m2. At the same time, the test result show that because of the difference between the ambient and seawater temperatures, the solar still could produce water at night, and the daily production could increase to 7.55 kg/day when the daily average solar radiation is 533 W/m2.
