description: We derive the timescale for two initially pure subsystems to become entangled with each other through an arbitrary Hamiltonian that couples them. The entanglement timescale is inversely proportional to the "correlated uncertainty" between the two subsystems, a quantity which we will define and analyze in this paper. Our result is still applicable when one of the subsystems started in an arbitrarily mixed state, thus it generalizes the well-known "decoherence timescale" while coupled to a thermal state.

description: The cellular cytoskeleton is an active material, driven out of equilibrium by molecular motor proteins. It is not understood how the collective behaviors of cytoskeletal networks emerge from the properties of the network's constituent motor proteins and filaments. Here we present experimental results on networks of stabilized microtubules in Xenopus oocyte extracts, which undergo spontaneous bulk contraction driven by the motor protein dynein, and investigate the effects of varying the initial microtubule density and length distribution. We find that networks contract to a similar final density, irrespective of the length of microtubules or their initial density, but that the contraction timescale varies with the average microtubule length. To gain insight into why this microscopic property influences the macroscopic network contraction time, we developed simulations where microtubules and motors are explicitly represented. The simulations qualitatively recapitulate the variation of contraction timescale with microtubule length, and allowed stress contributions from different sources to be estimated and decoupled.

description: Management of spontaneously emerging natural flora and invasive plant species (also known as ‘weeds’) is generally a main challenge in plant production and it is even more important under organic farming systems. Therefore, it is crucial to highlight effective strategies and methodologies of weed control. Besides selecting the right variety, the foundation for successful chickpea production lies in choosing the optimal sowing date, and implementing thoughtful management of spontaneously emerging flora and invasive species. Ensure that the soil temperature reaches at least 10-12°C before planting, as recent cold springs have often been too frosty. Exposure to cold can inhibit seed germination.It is crucial to assess the predominant weed species in the selected sowing area. In fields heavily infested with perennial plants (e.g., creeping thistle, bitter dock, convolvulus species), organic chickpea production should be reconsidered or potentially avoided.Pre-crops with strong weed suppression effects can significantly aid in weed control. Although crop rotation is often challenging to plan due to seasonal variability, cereals (e.g., winter wheat) are essential, and cover crops can also be beneficial.The choice of row spacing and planting density should be adapted to the available row-cropping tools. In irrigated areas, a false seedbed can be prepared to promote weed emergence, followed by a single mechanical weed control using a harrow. Weed control strategies may also include mixed sowings (e.g., flax/wheat/mustard/chickpea) or planting chickpea in mulch (direct sowing of chickpea after rolling rye).

description: Bothrops jararacussu venom’s (Bj2015) batch was biomonitored quarterly for one year to assess phospholipase A2 (PLA2) activity, immunogenicity, neurotoxicity, and myotoxicity. In silico models were applied to evaluate losses using decay model and recoveries by predictive trend analysis. Mice were immunized with Bj2015. Antibodies were detected by double-immunodiffusion and total protein and albumin were measured. Neuromuscular blockade-induced by 40 μg mL−1 venom solution was carried out using mouse nerve phrenic-diaphragm preparation. Resulting muscles were submitted to light microscopy to evaluate the myotoxicity. PLA2 activity of 0.1 mg mL−1 Bj2015 was measured using 4-nitro-3-(octanoyloxy)benzoic acid as substrate. Over time, greater losses occurred in neurotoxicity than PLA2, but not in myotoxicity and immunogenicity. Concluding, the neurotoxicity decrease can be related to enzymatic losses, including PLA2. Depending on the purpose of use, the collected venom responds on a long time, avoiding unnecessary new collections, improving life quality of animals in captivity and increasing their longevity.

В сухой степи влага является фактором, определяющим уровень урожайности сельскохозяйственных культур и формирования биомассы естественной растительностью. Коэффициент корреляции (r) между урожайностью яровой пшеницы и атмосферными осадками составил 0,8. Основой сельскохозяйственного землепользования в условиях вододефицитного Южного Урала должны быть эффективно использующие водные ресурсы системы использования земель с обеспечением сохранения их плодородия. Хозяйственная целесообразность развития орошения на Южном Урале обусловлена малой влагообеспеченностью сельскохозяйственных культур в богарном земледелии и большим коэффициентом неравномерности их урожайности по годам независимо от уровня агротехники. Предлагаемые пути повышения эффективности использования водных ресурсов на орошаемых землях позволят сохранить их плодородие, повысить биопродуктивность и биоразнообразие биоценозов и улучшить природные условия жизни населения и его хозяйственной деятельности.
Finite Mathematics, Finite Quantum Theory And A Conjecture On The Nature Of Time

description: We first give a rigorous mathematical proof that classical mathematics (involving such notions as infinitely small/large, continuity etc.) is a special degenerate case of finite one in the formal limit when the characteristic $p$ of the field or ring in finite mathematics goes to infinity. We consider a finite quantum theory (FQT) based on finite mathematics and prove that standard continuous quantum theory is a special case of FQT in the formal limit $p\to\infty$. The description of states in standard quantum theory contains a big redundancy of elements: the theory is based on real numbers while with any desired accuracy the states can be described by using only integers, i.e. rational and real numbers play only auxiliary role. Therefore, in FQT infinities cannot exist in principle, FQT is based on a more fundamental mathematics than standard quantum theory and the description of states in FQT is much more thrifty than in standard quantum theory. Space and time are purely classical notions and are not present in FQT at all. In the present paper we discuss how classical equations of motions arise as a consequence of the fact that $p$ changes, i.e. $p$ is the evolution parameter. It is shown that there exist scenarios when classical equations of motion for cosmological acceleration and gravity can be formulated exclusively in terms of quantum quantities without using space, time and standard semiclassical approximation.

В связи с этим выглядело символичным проведение в центре Европы Международной конференции «Советская степь культура, окружающая среда, экономика и политика» (International Conference «The Soviet Steppe Culture, Environment, Economics and Politics»). В статье представлен краткий обзор Международной конференции «Советская степь культура, окружающая среда, экономика и политика», которая проходила 15-16 февраля 2019 г. в Университете Фрибурга (Швейцария). Отражены взгляды и позиции зарубежных ученых по отношению к советскому периоду в истории степи и освоения степного пространства. В Западной Европе и США в области гуманитарных и естественных наук проявляется профессиональный интерес к проблемам освоения степного пространства Евразии. Зарубежные контакты в области степеведения позволяют расширить представления о социально-экономических и экологических последствиях освоения природных ресурсов СССР в 20 веке.

description: We study collisions between neutral, deuterated ammonia molecules (ND$_3$) stored in a 50 cm diameter synchrotron and argon atoms in co-propagating supersonic beams. The advantages of using a synchrotron in collision studies are twofold: (i) By storing ammonia molecules many round-trips, the sensitivity to collisions is greatly enhanced; (ii) The collision partners move in the same direction as the stored molecules, resulting in low collision energies. We tune the collision energy in three different ways: by varying the velocity of the stored ammonia packets, by varying the temperature of the pulsed valve that releases the argon atoms, and by varying the timing between the supersonic argon beam and the stored ammonia packets. These give consistent results. We determine the relative, total, integrated cross-section for $\mathrm{ND}_3+\mathrm{Ar}$ collisions in the energy range of 40-140 cm$^{-1}$, with a resolution of 5-10 cm$^{-1}$ and an uncertainty of 7-15%. Our measurements are in good agreement with theoretical scattering calculations.

Selecting the right sowing time in arable cultivation of cowpea (vigna unguiculata) (Deliverable 6.4)

description: Cowpea tolerates heat and extreme drought well. However, it is highly intolerant of competition, with any significant emergence of natural flora leading to a noticeable yield reduction. Post-sowing cold spells or insufficient soil temperatures can cause delayed germination and reduced seedling emergence. While cowpea can tolerate some thinning, excessive gaps in plant coverage — especially due to delayed germination — can give weeds a competitive edge, negatively impacting the entire cultivation cycle. Achieving uniform plant coverage is essential, and the key to this lies in selecting the right sowing time with optimal soil temperatures. Ideal germination occurs when soil temperatures are at least 15-18°C. However, sowing later rather than earlier is recommended to avoid the risks associated with cool soil conditions. Effective weed control measures are also crucial for a successful yield. Delay sowing until late May or early June, when soil temperature is as high as 20°C. This will,ensure moist seedbeds, or applying irrigation to promote germination can result in an explosive emergence. In conventional farming systems, a single post-emergent herbicide treatment can help maintain a relatively weed-free crop. In organic farming, shallow tillage is crucial for spontaneous flora management. This latter practice preserves moisture in the soil while removing emerging weeds from the top layer without bringing up new weed seeds. Additionally, two rounds of inter-row cultivation can keep the field largely weed-free. Any significant weed presence will result in a marked reduction in yield.

description: We discuss the three spacetime dimensional $\mathbb{C}\mathbb{P}^N$ model and specialize to the $\mathbb{C}\mathbb{P}^1$ model. Because of the Hopf map $π_3(\mathbb{C}\mathbb{P}^1)=\mathbb{Z}$ one might try to couple the model to a periodic $θ$ parameter. However, we argue that only the values $θ=0$ and $θ=π$ are consistent. For these values the Skyrmions in the model are bosons and fermions respectively, rather than being anyons. We also extend the model by coupling it to a topological quantum field theory, such that the Skyrmions are anyons. We use techniques from geometry and topology to construct the $θ=π$ theory on arbitrary 3-manifolds, and use recent results about invertible field theories to prove that no other values of $θ$ satisfy the necessary locality.

description: Online social networks, World Wide Web, media and technological networks, and other types of so-called information networks are ubiquitous nowadays. These information networks are inherently heterogeneous and dynamic. They are heterogeneous as they consist of multi-typed objects and relations, and they are dynamic as they are constantly evolving over time. One of the challenging issues in such heterogeneous and dynamic environments is to forecast those relationships in the network that will appear in the future. In this paper, we try to solve the problem of continuous-time relationship prediction in dynamic and heterogeneous information networks. This implies predicting the time it takes for a relationship to appear in the future, given its features that have been extracted by considering both heterogeneity and temporal dynamics of the underlying network. To this end, we first introduce a feature extraction framework that combines the power of meta-path-based modeling and recurrent neural networks to effectively extract features suitable for relationship prediction regarding heterogeneity and dynamicity of the networks. Next, we propose a supervised non-parametric approach, called Non-Parametric Generalized Linear Model (NP-GLM), which infers the hidden underlying probability distribution of the relationship building time given its features. We then present a learning algorithm to train NP-GLM and an inference method to answer time-related queries. Extensive experiments conducted on synthetic data and three real-world datasets, namely Delicious, MovieLens, and DBLP, demonstrate the effectiveness of NP-GLM in solving continuous-time relationship prediction problem vis-a-vis competitive baselines

Pronto saro' bensi' di ubbidire agli ordini di questa nostra Accademia, e di giovare ad ogni accademico in particolare. La prego di farla partecipe di questi miei sentimenti, e del mio ringraziamento. Mi auguro di avere qualche occasione di fare anche conoscere a Lei quanto divotamente mi rassegno

description: Principia Logico-Metaphysica contains a foundational logical theory for metaphysics, mathematics, and the sciences. It includes a canonical development of Abstract Object Theory [AOT], a metaphysical theory (inspired by ideas of Ernst Mally, formalized by Zalta) that distinguishes between ordinary and abstract objects. This article reports on recent work in which AOT has been successfully represented and partly automated in the proof assistant system Isabelle/HOL. Initial experiments within this framework reveal a crucial but overlooked fact: a deeply-rooted and known paradox is reintroduced in AOT when the logic of complex terms is simply adjoined to AOT's specially-formulated comprehension principle for relations. This result constitutes a new and important paradox, given how much expressive and analytic power is contributed by having the two kinds of complex terms in the system. Its discovery is the highlight of our joint project and provides strong evidence for a new kind of scientific practice in philosophy, namely, computational metaphysics. Our results were made technically possible by a suitable adaptation of Benzmüller's metalogical approach to universal reasoning by semantically embedding theories in classical higher-order logic. This approach enables one to reuse state-of-the-art higher-order proof assistants, such as Isabelle/HOL, for mechanizing and experimentally exploring challenging logics and theories such as AOT. Our results also provide a fresh perspective on the question of whether relational type theory or functional type theory better serves as a foundation for logic and metaphysics.

description: Цель. Выявление исторического опыта разработки и внедрения приёмов природоподобного неразрушительного землепользования в трудах классиков отечественного земледелия, изучение вклада учёных в агрономическую науку, теорию и практику ресурсосберегающего землепользования. Материалы и методы. Объектом исследования являлось агрономическое наследие передовых учёных российской сельскохозяйственной науки и агрономов практиков, для которых чернозёмная полоса России с её пошатнувшимся плодородием и участившимися засухами, следовавшими практически непрерывной чередой, и особенно страшной засухи 1891 и 1892 гг., породившей небывалые страдания, нищету и голод населения России, стала предметом пристального исследования. Для достижения поставленной цели использовались методы теоретического контент анализа первоисточников, обобщения и систематизации полученных результатов. Результаты. В комплексности подхода к выявлению причин усиления засушливости и снижения плодородия степных почв наиболее примечательны работы В.В. Докучаева, К.А. Тимирязева, П.А. Костычева и А.А. Измаильского, показавших, что засушливые проявления представляют собой явления не всегда климатические, а почти исключительно почвенно ландшафтные, зачастую «подготовленные» земледельческой практикой. Они указывали, что сельское хозяйство XIX века, в степных регионах страны являлось своеобразной биржевой игрой, которое, не считаясь с нарушением первозданности ландшафтов, было нацелено только на извлечение максимальной прибыли. При таком подходе нет ничего удивительного во всё более и более частом повторении засух. Заключение. Предшествующими поколениями гениальных отечественных учёных аграриев накоплен огромный опыт конструирования прибыльных, неразрушительных и экологоориентированных агроландшафтов. Грамотное наложение на этот фундамент современных приёмов «умного землепользования» может рассматриваться как реальный путь выхода из экологического кризиса, поскольку именно ландшафтный подход даёт самые стабильные и надёжные результаты при внедрении приемов природоподобного неразрушительного землепользования во всём мире.
Optomechanical analogy for a toy cosmology with a quantized scale factor

description: The simplest cosmology --- the Friedmann-Robertson-Walker-Lemaître (FRW) model --- describes a spatially homogeneous and isotropic universe where the scale factor is the only dynamical parameter. Here we consider how quantized electromagnetic fields become entangled with the scale factor in a toy version of the FRW model. A system consisting of a photon, source, and detector is described in such a universe, and we find that the detection of a redshifted photon by the detector system constrains possible scale factor superpositions. Thus, measuring the redshift of the photon is equivalent to a weak measurement of the underlying cosmology. We also consider a potential optomechanical analogy system that would enable experimental exploration of these concepts. The analogy focuses on the effects of photon redshift measurement as a quantum back-action on metric variables, where the position of a movable mirror plays the role of the scale factor. By working in the rotating frame, an effective Hubble equation can be simulated with a simple free moving mirror.

Organisational solutions for pre-processing and processing (Deliverable 6.4)
Creators: name: Clair, Dylan
Publisher: name: Zenodo
Year: 2024

description: Many farmers, especially organic, would like to pre-process harvested crops before delivering it to their customer or to the cooperative. If they deliver raw grains, possibly polluted by weeds, the price is low and the cooperative can charge them cleaning fees. But pre-processing equipment, such as sorter or dehuller, can be expensive and difficult to amortise especially for small businesses. Furthermore, some skills are needed for the design and the installation of such machineries.These issues may lead farmers to expose themselves to significant financial investments and increased working time that need to be mitigated. Two collective organisation examples are given from the Cerr-Occ living lab (Occitania, France) 1) a mobile grain cleaning unit, for which some farmers have organised themselves to collectively buy and use a mobile grain sorting unit.2) a processing unit, including cleaning/sorting and dehulling unit and stone mill, entirely owned by a cooperative.  A number of farmers have come together to form a cooperative called SCIC Graines Equitables, which focuses on the production of certified organic cereals, pulses and processing products such flour, pasta and aperitive seeds. No matter what is the collective organisation considered, it is important to be supported by specialists. The pro-ject must technically meet the expectations of the community, while remaining within investment levels that will generate added value in the medium term.The collective aspect is also very important, often requiring external leadership and the establishment of clear, shared collective rules.

description: We suggest a single-mode spin injection scheme in non-ferromagnetic quantum channels utilizing perpendicular strong Rashba spin-orbit and Zeeman fields. By applying a positive top-gate potential in order to inject electrons from the spin-orbit gap to the low-energy regime, we observe coherent destruction of transport signatures of a hole-like quasi-bound state, an electron-like quasi-bound state, or a hole-like bound state features that are sensitive to the selection of the top-gate length along the transport direction.

Orbital advection with magnetohydrodynamics and vector potential

description: Orbital advection is a significant bottleneck in disk simulations, and a particularly tricky one when used in connection with magnetohydrodynamics. We have developed an orbital advection algorithm suitable for the induction equation with magnetic potential. The electromotive force is split into advection and shear term, and we find that we do not need an advective gauge as solving the orbital advection implicitly precludes the shear term from canceling the advection term. We prove and demonstrate the third order in time accuracy of the scheme. The algorithm is also suited for non-magnetic problems. Benchmarked results of (hydrodynamical) planet-disk interaction and the of the magnetorotational instability are reproduced. We include detailed descriptions of the construction and selection of stabilizing dissipations (or high frequency filters) needed to generate practical results. The scheme is self-consistent, accurate, and elegant in its simplicity, making it particularly efficiently in straightforward finite-difference methods. As a result of the work, the algorithm is incorporated in the public version of the Pencil Code, where it can be used by the community.

description: Цель. Повышение эффективности удобрений и урожайности яровой пшеницы за счёт получения сверхранних всходов и результативности использования растениями весенних запасов влаги и осадков вегетационного периода. Материалы и методы. Исследована отзывчивость растений и посевов яровой пшеницы подзимнего срока сева на подкормки жидкими минеральными удобрениями на черноземе обыкновенном Предуралья. Опыт проведен в соответствии с методикой опытного дела (Б.А. Доспехов, 2005; Госсортсети, 1981). Результаты. Подзимний посев яровой пшеницы обеспечивает более раннее появление всходов и развитие растений в благоприятных водных и температурных условиях, в сравнении с весенними посевами, повышает продуктивность использования воды и 1,6 раза урожайность. Подкормка жидкими минеральными удобрениями «Агрис» «Азот» обеспечивает прибавку урожайности зерна яровой пшеницы подзимнего посева, на 26,5 % по отношению к варианту без удобрений и в 1,8 раза повышает эффективность использования ими влаги. Дополнение азотных удобрений серосодержащим препаратом «Аминовит Сера» уменьшает дефицит серы, обусловленной большим количеством меди в почвах, приуроченных к местам добычи медной руды, и повышает урожайность ещё на 18 %. Заключение. Подзимний посев и подкормка в фазу кущения яровой пшеницы жидкими минеральными удобрениями, содержащими азот и серу, на почвах с дефицитом их, повышают эффективность влаги, удобрений и урожайность яровой пшеницы.
On the Possibility of Fast Radio Bursts from Inside Supernovae: The Case of SN 1986J

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We discuss the possibility of obtaining Fast Radio Bursts (FRBs) from the interior of supernovae, in particular SN 1986J. Young neutron stars are involved in many of the possible scenarios for the origin of FRBs, and it has been suggested that the high dispersion measures observed in FRBs might be produced by the ionized material in the ejecta of associated supernovae. Using VLA and VLBI measurements of the Type IIn SN 1986J, which has a central compact component not so far seen in other supernovae, we can directly observe for the first time radio signals which originate in the interior of a young (~30 yr old) supernova. We show that at age 30 yr, any FRB signal at ~1 GHz would still be largely absorbed by the ejecta. By the time the ejecta have expanded so that a 1-GHz signal would be visible, the internal dispersion measure due to the SN ejecta would be below the values typically seen for FRBs. The high dispersion measures seen for the FRBs detected so far could of course be due to propagation through the intergalactic medium provided that the FRBs are at distances much larger than that of SN 1986J, which is 10 Mpc. We conclude that if FRBs originate in Type II SNe/SNRs, they would likely not become visible till 60 ~ 200 yr after the SN explosion.
