Nonlocality, Bell's Ansatz and Probability

Quantum Mechanics lacks an intuitive interpretation, which is the cause of a generally formalistic approach to its use. This in turn has led to a certain insensitivity to the actual meaning of many words used in its description and interpretation. Herein, we analyze carefully the possible mathematical meanings of those terms used in analysis of EPR's contention, that Quantum Mechanics is incomplete, as well as Bell's work descendant therefrom. As a result, many inconsistencies and errors in contemporary discussions of nonlocality, as well as in Bell's Ansatz with respect to the laws of probability, are identified. Evading these errors precludes serious conflicts between Quantum Mechanics and both Special Relativity and Philosophy.Comment: 8&1/2 pages revtex; v2: many corrections, clairifications & extentions, all small; v3: editorial scru

Using the gene pool of CIMMYT cultivars and lines in spring durum wheat breeding in Western Siberia

Background. Preservation and expansion of the source material genetic diversity and its purposeful use is the basis for the development of adaptable spring durum wheat cultivars for the environments of Western Siberia.Materials and methods. The target research material included the cultivars and promising material of Triticum durum Desf. developed in the Spring Durum Wheat Breeding Laboratory of Omsk Agrarian Scientific Center as well as the gene pool of cultivars and lines obtained under the CIMMYT International Cooperation Program. Field trials, disease resistance assessment and phenological observations were carried out on the experimental fields of the Institute in 2000–2020 according to generally accepted methods. Principal component analysis was carried out using the R version of the 4.0.3 package.Results. The studies have shown that CIMMYT lines differ from local cultivars and lines in disease resistance (brown rust, stem rust, hard smut, and powdery mildew), test weight, pasta-making properties, and lodging resistance, but under the conditions of Western Siberia they are significantly inferior in adaptability to local cultivars and lines and suffer greatly from drought, especially during the grain-filling period. In the genetic control of the studied traits, the additive-dominant system with the inclusion of the complementary recessive epistasis prevails. Local cultivars dominated in most of the studied traits, except the stem length, and the length and diameter of the second internode, where short-stemmed cultivars affected the degree of the traits’ expression in hybrids.Conclusion. The result of such activity was the release of cv. ‘Omsky Korall’, which combines high yield, adaptability to the climate of Western Siberia, and resistance to the local population of Puccinia graminis Pers. f. sp. tritici Erikss. et Henn. and Ug99, with excellent pasta-making properties, as well as the presence of promising lines in all breeding nurseries

Is "entanglement" always entangled?

Entanglement, including ``quantum entanglement,'' is a consequence of correlation between objects. When the objects are subunits of pairs which in turn are members of an ensemble described by a wave function, a correlation among the subunits induces the mysterious properties of ``cat-states.'' However, correlation between subsystems can be present from purely non-quantum sources, thereby entailing no unfathomable behavior. Such entanglement arises whenever the so-called ``qubit space'' is not afflicted with Heisenberg Uncertainty. It turns out that all optical experimental realizations of EPR's \emph{Gedanken} experiment in fact do not suffer Heisenberg Uncertainty. Examples will be analyzed and non-quantum models for some of these described. The consequences for experiments that were to test EPR's contention in the form of Bell's Theorem are drawn: \emph{valid tests of EPR's hypothesis have yet to be done.}Comment: 5 p.

Promising genetic sources for the creation of varieties of durum spring wheat in Western Siberia

The study, expansion and preservation of the genetic diversity of the source material, and its purposeful use in hybridization is the basis for the creation of adaptive varieties of durum spring wheat that are resistant to biotic and abiotic factors of the environment of Western Siberia. The objects of research were samples of durum spring wheat. Over the years of research (2000–2020), about 3 thousand samples were worked out from the world gene pool of various countries and regions: from the collection of the VIR, the gene pool from Mexico (CIMMYT) within the framework of the agreement and cooperation program (2000–2007), from 2000 to the present time under the program of the Kazakh-Siberian Spring Wheat Breeding Network (KASIB), from other scientific institutions of Russia in exchange activities. Using generally accepted techniques, the obtained material was studied for a complex of traits: yield, adaptability, grain quality, resistance to diseases. In the cycle of studying the gene pool from CIMMYT, 50 genotypes were identified in terms of yield at the level of the Omskaja jantarnaja standard, 276 grains by test weight, 131 samples by pasta color, 131 samples by resistance to hard smut, and 112 by resistance to powdery mildew. Almost all samples were not affected by leaf rust. The study set showed high sensitivity to extreme conditions and most forms of interest in quality and disease resistance were low-productive in our environment. In KASIB nurseries, 29 samples were identified in terms of yield and adaptability, 29 samples in terms of grain quality, 21 in terms of resistance to diseases, including 8 resistant to stem rust. In the set of varieties received from the VIR, 15 genotypes were adaptive, 16 had high grain quality, 11 were resistant to stem rust. In the breeding material, 17 samples of the local population resistant to stem rust (6 of them were comprehensively resistant) and 25 race-resistant to Ug99 were identified. The genotypes identified as a result of research are of interest as sources of valuable traits

Оценка адаптивной способности и взаимодействий генотипа и среды перспективных линий яровой твердой пшеницы в условиях Омской области

The stability of grain production largely depends on prevailing weather conditions and cultivation technology. It also depends on the ability of the variety to maintain a high-level yield and grain quality under adverse environmental conditions. The study aims to determine the adaptive properties and genotype-medium interactions in yield formation in spring durum wheat lines. The authors conducted field research in 2019-2021 based on the breeding rotation of the durum wheat breeding laboratory of the FSBSI Omsk Research Center. The authors also conducted research at a seed production site in the steppe zone in the village of Novouralskiy, Tavrinsky district, Omsk region. Competitive varietal trials were laid on the pure pairing of 40 numbers and three registry varieties. The area of the plots was ten m², the repetition was double, and the placement was randomized. Weather conditions were contrasting both in terms of precipitation and temperature regime. Atypical meteorological conditions prevailed in 2019: favorable in the first vegetation period and drought conditions in the second (Volga type of drought). Drought conditions were observed throughout the summer of 2020. The most unfavorable conditions for grain filling and ripening occurred in 2021. Ecological plasticity parameters were calculated according to S.A. Eberhart and W.A. Russel. AMMI-analysis (additive main effect and multiplicative interaction) were determined according to R.W Zobel et al. The analysis showed the effectiveness of differentiation of genotype response to the environment by AMMI-analysis and the model of S.A. Eberhart, W.A. Russell. At the same time, AMMI analysis with graphs was more informative. The varieties Gordeiforme 11-70-7-7, Gordeiforme 11-47-1, and Gordeiforme 11-49-1-1 proved to be most responsive to changing growing conditions. The genotypes Gordeiforme 14-83-1, Gordeiforme 13-18-3, and Gordeiforme 13-37-2 stably form high productivity. The line of the variety Gordeiforme 12-11-7 has the least interaction between genotype and environment.Стабильность производства зерна во многом зависит от складывающихся погодных условий, технологии возделывания и способности сорта сохранить высокий уровень урожайности и качества зерна при воздействии неблагоприятных условий среды. Цель исследований – определение адаптивных свойств и генотип-средовых взаимодействий в формировании урожайности у линий яровой твердой пшеницы. Полевые исследования выполнялись в 2019–2021 гг. на базе селекционного севооборота лаборатории селекции твердой пшеницы ФГБНУ «Омский АНЦ», а также на опорном пункте семеноводства в степной зоне в пос. Новоуральский Таврического района Омской области. Конкурсное сортоиспытание было заложено по чистому пару в количестве 40 номеров и 3 реестровых сорта. Площадь делянок 10 м², повторность двукратная, размещение рендомизированное. Погодные условия отличались контрастностью как по осадкам, так и по температурному режиму. В 2019 г. сложились нетипичные метеорологические условия: благоприятные в первый период вегетации и засушливые во второй (поволжский тип засухи), в 2020 г. засуха наблюдалась в течение всего лета. Самые неблагоприятные условия для налива и созревания зерна складывались в 2021 г. Параметры экологической пластичности рассчитывали по S.A. Eberhart, W.A. Russel. Эффекты аддитивных и мультипликативных взаимодействий (АММИ-анализ) были определены по R.W Zobel и др. Проведенный анализ показал эффективность дифференциации реакции генотипа на окружающую среду AMMI-анализа и модели S.A. Eberhart, W.A. Russell. В то же время AMMI-анализ с отображением графиков был более информативен. Наиболее отзывчивыми на изменение условий произрастания оказались Гордеиформе 11-70-7, Гордеиформе 11-47-1 и Гордеиформе 11-49-1-1. Стабильно формируют высокую продуктивность генотипы Гордеиформе 14-83-1, Гордеиформе 13-18-3, Гордеиформе 13-37-2. Наименьшее взаимодействие генотипа и среды отмечается у линии Гордеиформе 12-11-7
