description: Soybeans are an important crop for global food security. Every year, soybean yields are reduced by numerous soybean diseases, particularly the soybean cyst nematode (SCN). It is difficult to visually identify the presence of SCN in the field, let alone its population densities or numbers, as there are no obvious aboveground disease symptoms. The only definitive way to assess SCN population densities is to directly extract the SCN cysts from soil and then extract the eggs from cysts and count them. Extraction is typically conducted in commercial soil analysis laboratories and university plant diagnostic clinics and involves repeated steps of sieving, washing, collecting, grinding, and cleaning. Here we present a robotic instrument to reproduce and automate the functions of the conventional methods to extract nematode cysts from soil and subsequently extract eggs from the recovered nematode cysts. We incorporated mechanisms to actuate the stage system, manipulate positions of individual sieves using the gripper, recover cysts and cyst-sized objects from soil suspended in water, and grind the cysts to release their eggs. All system functions are controlled and operated by a touchscreen interface software. The performance of the robotic instrument is evaluated using soil samples infested with SCN from two farms at different locations and results were comparable to the conventional technique. Our new technology brings the benefits of automation to SCN soil diagnostics, a step towards long-term integrated pest management of this serious soybean pest.

description: This paper addresses the problem of integrating local guide policies into a Reinforcement Learning agent. For this, we show how to adapt existing algorithms to this setting before introducing a novel algorithm based on a noisy policy-switching procedure. This approach builds on a proper Approximate Policy Evaluation (APE) scheme to provide a perturbation that carefully leads the local guides towards better actions. We evaluated our method on a set of classical Reinforcement Learning problems, including safety-critical systems where the agent cannot enter some areas at the risk of triggering catastrophic consequences. In all the proposed environments, our agent proved to be efficient at leveraging those policies to improve the performance of any APE-based Reinforcement Learning algorithm, especially in its first learning stages.

description: Doing business internationally is a global thread in the 20th century; the GDP has a 40 percent difference if you connect to a global goods and services network (Manyika, 2024) or not. However, it also means it will have two or more cultures colliding together. Trompenaars (2021) points out the main dilemma when it comes to cross-cultural business: centralization versus decentralization. Decentralization means each culture goes its own way with the idea of more local better. Centralization means principles need to be the same in different countries. Decentralization can be done in individualistic cultures more like western culture, but not as a family model in eastern countries (Trompenaars, 2021). Culture differences in the business era often exist in the way people view friendship and contracts, the relationship between business partner and government. Cross-culture management, which provides more culture awareness and flatter organization, is the way to reconcile the culture problem nowadays in international companies like Tesla.

description: Monocular depth estimation (MDE) is essential for numerous applications yet is impeded by the substantial computational demands of accurate deep learning models. To mitigate this, we introduce a novel Teacher-Independent Explainable Knowledge Distillation (TIE-KD) framework that streamlines the knowledge transfer from complex teacher models to compact student networks, eliminating the need for architectural similarity. The cornerstone of TIE-KD is the Depth Probability Map (DPM), an explainable feature map that interprets the teacher's output, enabling feature-based knowledge distillation solely from the teacher's response. This approach allows for efficient student learning, leveraging the strengths of feature-based distillation. Extensive evaluation of the KITTI dataset indicates that TIE-KD not only outperforms conventional response-based KD methods but also demonstrates consistent efficacy across diverse teacher and student architectures. The robustness and adaptability of TIE-KD underscore its potential for applications requiring efficient and interpretable models, affirming its practicality for real-world deployment.

The Flower Calculus

Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: We introduce the flower calculus, a deep inference proof system for intuitionistic first-order logic inspired by Peirce's existential graphs. It works as a rewriting system over inductive objects called ''flowers'', that enjoy both a graphical interpretation as topological diagrams, and a textual presentation as nested sequents akin to coherent formulas. Importantly, the calculus dispenses completely with the traditional notion of symbolic connective, operating solely on nested flowers containing atomic predicates. We prove both the soundness of the full calculus and the completeness of an analytic fragment with respect to Kripke semantics. This provides to our knowledge the first analyticity result for a proof system based on existential graphs, adapting semantic cut-elimination techniques to a deep inference setting. Furthermore, the kernel of rules targetted by completeness is fully invertible, a desirable property for both automated and interactive proof search.

description: This paper presents an all-fiber telecom-range optical gyroscope employing a spontaneous parametric down conversion crystal to produce ultra-low intensity thermal light by tracing-out one of the heralded photons. The prototype exhibits a detection limit on photon delay measurements of $249$ zs over a $72$ s averaging time and 26 zs in differential delay measurements at $t=10^4$ s averaging. The detection scheme proves to be the most resource-efficient possible, saturating $>99.5\%$ of the Cramér-Rao bound. These results are groundbreaking in the context of low-photon regime quantum metrology, paving the way to novel experimental configurations to bridge quantum optics with special or general relativity.

description: Preschool mealtimes may be an overlooked context and an underutilized opportunity for teachers to support the development of children’s social–emotional competence and healthy eating habits. Emotion-focused teaching—how teachers model their own emotions, respond to children’s emotions and instruct about emotions—and responsive feeding practices—provider behaviors and mealtime environments that support healthy eating behaviors— can be both be employed during mealtimes to support these learning outcomes, but guidance for teachers during mealtimes is limited. guidance The purpose of this study is to understand how these practices are employed (or not employed) at mealtimes, and the relationship between them. Mealtime video footage (n=107) from 17 preschool classrooms were assessed using observational tools including the EMOtion TEaching Rating Scale (EMOTERS) to measure emotion-focused teaching, and the Mealtime Observation Childcare Checklist (MOCC) to measure adherence to recommended feeding practices. Additionally, this study identifies aspects of mealtimes that challenge, support, or provide opportunities for emotion-focused teaching. Emotion-focused teaching scores during mealtimes are low to moderate and instructing practices are rarely used. Responsive feeding scores were also low , and few mealtimes were observed to have indicators of family-style meal service. There was a significant, albeit weak, negative association between total MOCC and EMOTERS scores as well as between the Sensory Exploration subscale of the MOCC and the Modeling domain of the EMOTERS. However, given the limitations of this study, these findings do not support the hypothesis that there are clear relationships between emotion-teaching scores and responsive feeding practices or indicators of family-style meal service. An analysis of mealtime events and interactions (e.g., spills) demonstrate that mealtimes present several challenges to emotion-focused teaching, but also offer many opportunities to use such practices. Opportunities include: avoiding negativity when responding to spills; making space for playfulness and sensory exploration of food; handling misbehavior by explaining how it affects others, and addressing underlying emotions; creating and leveraging personal conversations as an opportunity for emotion-focused teaching; using emotionally-supportive strategies to encourage eating; and sitting and engaging with children at the table.

description: Ultracold atomic spin mixtures develop rich and intriguing magnetic properties when an external radiation coherently couples different spin states. In particular, the coupled mixture may acquire a critical behavior when the spin interactions equal the coupling energy. However, atomic mixtures generally feature a relatively high sensitivity to magnetic fields that can set a limitation to the observable phenomena. In this article, we present an overview of experimental studies of magnetism based on superfluid multicomponent gases in an ultrastable magnetic field environment, which recently became available.

description: La apendicitis aguda es una enfermedad que desde la antigüedad tenía una mortalidad abrumadora, ya que se desconocía su fisiopatología y por lo tanto su tratamiento. A medida que fue avanzando la medicina con las descripciones anatómicas, se pudo asociar la causa a ésta pequeña estructura y con los posteriores descubrimientos de la anestesia, es que fue posible pensar en un manejo quirúrgico y tratar esta patología. En la actualidad es una enfermedad con baja mortalidad, aunque hay casos donde se presenta con complicaciones que pueden ser locales o sistémicas con gran relevancia clínica y pronóstica para los pacientes.
Hay pacientes que sufren apendicitis complicada, ya sea por comorbilidades, retraso en la atención o falta de recursos para obtener un tratamiento médico adecuado. El manejo de estos pacientes puede llegar a ser complejo, por lo que tener una herramienta que sea económica, accesible y confiable, que ayude a clasificar a estos pacientes dentro de la categoría de apendicitis complicada, sería de gran utilidad.Por medio de un análisis retrospectivo de 362 pacientes con apendicitis aguda en un hospital de segundo nivel en México, se demostró que 159 (43.9%) pacientes con apendicitis aguda complicada presentaban hiponatremia con un OR de 1.744 con un IC del 95% (1.131-2.689), y al cruzar las dos poblaciones se encontró una p= 0.012, demostrando estadísticamente que la hiponatremia está presente en los pacientes con apendicitis complicada.Según los hallazgos en la literatura y en los resultados obtenidos por esta investigación se puede afirmar que existe un fuerte asociación entre la hiponatremia y la apendicitis complicada. Por lo que se debe considerar el uso de los electrolitos ´séricos en el abordaje inicial de los pacientes en quienes se sospeche apendicitis aguda.

description: Watermelon (Citrullus lanatus) and Banana (Musa acuminata) peels are lignocellulosic agricultural waste that has the potential to produce bioethanol as a renewable form of energy. Bioethanol is an alternative liquid fuel produced from biomass that contained large amount of sugar (e.g sugarcane grain or biomass of lignocellulosic). This study was carried out to the process of pretreating Citrullus lanatus (watermelon) and Musa acuminata (Banana) with liquid hot water and bacteria. Bacteria were isolated from soil using microbiological methods. Pretreatment potentials were identified by determining the structural composition of the sample before and after pretreatment. Occurrence of bacterial isolates from soil, Bacillus cereus (3), Micrococcus spp (1), Bacillus subtilis (8). A. niger was isolated from soil which was used for hydrolysis. Biological pretreatment produced more lignin (13%) and (10%) for watermelon and banana peels respectively and hemicelluloses (23%) and (21%) for watermelon and banana respectively. The pretreatment with Liquid hot water which yielded less reduction in lignin concentration (11%) and (09%) of watermelon and banana respectively. This research showed that pretreatment of the fruit peels with Bacillus subtilis can increase accessibility of plant component during enzymatic saccharification.

description: Superconductor-semiconductor hybrid devices, involving quantum dots interfaced with floating and/or grounded superconductors, have reached a level of complexity which calls for the development of versatile and numerically efficient modelling tools. Here, we propose an extension of the surrogate model solver for sub-gap states [Phys. Rev. B 108, L220506 (2023)], which is able to handle floating superconducting islands with finite charging energy. Upon eliminating all finite-size effects of the computationally demanding Richardson model approach, we achieve a more efficient way of calculating the sub-gap spectra and related observables without compromising their accuracy. We provide a number of benchmarks between the two approaches and showcase the versatility of the extended surrogate model solver by studying the stability of spin-triplet ground states in various tunable devices. The methods introduced here set the stage for reliable microscopic simulations of complex superconducting quantum circuits across all their relevant parameter regimes.

description: Transnational migration occurs in the flows of capital and people that are essential in the discourse of economic cooperation and cultural communication caused by factors including globalisation. In this context, many Chinese women independently migrated to Australia for work and/or study, or dependently migrated as tied movers to their husbands. Chinese women are now among the largest group of migrants in the 21st century Australia. However, the understanding of transnational motherhood through studying Chinese women's maternal experiences in this context is silent in existing literature.To investigate Chinese women's lived experiences of being a mother in a culturally and linguistically diverse society, the concepts of migration, identity, identification, transnationalism, and community and a qualitative case study approach were used in this study. A purposive sampling technique and snowball sampling technique were used to recruit seventeen self -identified Chinese women in one regional town and three metropolitan cities in Australia. Semi - structured interviews and literature were used for the main data sources.Three themes emerged from bilingual and recursive thematic analysis: (1) Migrating to Australia: becoming, that illuminated the profile of these Chinese mothers, factors influencing their movements and experiences after migration; (2) Symbols of `Chineseness': belonging, that described the language of Chineseness, images of Chineseness, and cognition of Chineseness; and (3) Not rong ru completely: adjusting, that demonstrated the approaches through which these Chinese mothers strove to integrate into Australian society and the outcome of these attempts. It is not assimilate completely but adjusting to some degree.Through constant comparison among these themes, it was found that zhong xi he bi is these Chinese women's lived experiences of being a mother in 21st century Australia. This metaphorical concept depicts the phenomenon of transnational motherhood.These findings have both theoretical and practical significance. Theoretically, investigating the phenomenon of transnational motherhood by using concepts of migration, identification, and community provides a new insight into this trans-disciplinary field. Practically, this study is of significance to the participants themselves and other people who wish to know about the cultural beliefs and practices of Chinese women in their childrearing. Particularly, it is of critical significance for clinicians who work with Chinese women in Australia and other countries, educators in early childhood, school, adult and community education sectors, policy makers, and the organisers of educational and medical intervention programs worldwide.

description: The L-fractional derivative is defined as a certain normalization of the well-known Caputo derivative, so alternative properties hold: smoothness and finite slope at the origin for the solution, velocity units for the vector field, and a differential form associated to the system. We develop a theory of this fractional derivative as follows. We prove a fundamental theorem of calculus. We deal with linear systems of autonomous homogeneous parts, which correspond to Caputo linear equations of non-autonomous homogeneous parts. The associated L-fractional integral operator, which is closely related to the beta function and the beta probability distribution, and the estimates for its norm in the Banach space of continuous functions play a key role in the development. The explicit solution is built by means of Picard's iterations from a Mittag-Leffler-type function that mimics the standard exponential function. In the second part of the paper, we address autonomous linear equations of sequential type. We start with sequential order two and then move to arbitrary order by dealing with a power series. The classical theory of linear ordinary differential equations with constant coefficients is generalized, and we establish an analog of the method of undetermined coefficients. The last part of the paper is concerned with sequential linear equations of analytic coefficients and order two.

Entrainment of Hot Gas into Cold Streams: The Origin of Excessive Star-formation Rates at Cosmic Noon

description: We explore the evolution of cold streams from the cosmic web that feed galaxies through their shock-heated circumgalactic medium (CGM) at cosmic noon, $z\simeq 1-5$. In addition to the hydrodynamical instabilities and radiative cooling that we have incorporated in earlier works, we embed the stream and the hot CGM in the gravitational potential of the host dark-matter halo, deriving equilibrium profiles for both. Self-gravity within the stream is tentatively ignored. We find that the cold streams gradually entrain a large mass of initially hot CGM gas that cools in the mixing layer and condenses onto the stream. This entrainment, combined with the acceleration down the gravitational potential well, typically triples the inward cold inflow rate into the central galaxy, compared to the original rate at the virial radius, which makes the entrained gas the dominant source of gas supply to the galaxy. The potential sources for the hot gas to be entrained are recycled enriched gas that has been previously ejected from the galaxy, and fresh virial-shock-heated gas that has accumulated in the CGM. This can naturally elevate the star formation rate in the galaxy by a factor of $\sim 3$ compared to the gas accretion rate onto the halo, thus explaining the otherwise puzzling observed excess of star formation at cosmic noon. When accounting for self-shielding of dense gas from the UV background, we find that the energy radiated from the streams, originating predominantly from the cooling of the entrained gas, is consistent with observed Lyman-$α$ blobs around galaxies.

description: The elliptic azimuthal anisotropy coefficient ($v_{2}$) of open-charm hadron at midrapidity ($|η<1|$) was studied in p--Pb collisions at $\sqrt{s_{\mathrm{NN}}}=$ 8.16 TeV using a multi-phase transport (AMPT) model included an additional charm quark--antiquark pair production trigger. The model provides a simultaneously description of the measured $p_{\mathrm{T}}$ spectrum and $v_{2}$ of $D^{0}$ meson, as well as the $v_{2}$ of light flavor meson $K_{s}^{0}$. We found that the $D^{0}$ and $K_{s}^{0}$ $v_{2}$ are both significantly affected by different parton scatterings among charm and light quarks. In addition, the predictions for the $v_{2}$ of other charm hadrons including $D^{+}$, $D_{s}^{+}$ and $Λ_{c}^{+}$ in p--Pb collisions are given for the first time. The $v_{2}$ of open-charm hadron reasonably follows the number-of-constituent-quark (NCQ) scaling up to 2.5 GeV, strongly indicating the importance of partonic degrees of freedom for the collectivity of heavy flavors in high-multiplicity p--Pb collisions. These findings may hint the formation of deconfined matter in small collision systems, and provide referential value for future measurements of azimuthal anisotropy at the LHC energies.

description: Modern trains act as Faraday cages making it challenging to provide high cellular data capacities to passengers. A solution is the deployment of linear cells along railway tracks, forming a cellular corridor. To provide a sufficiently high data capacity, many cell sites need to be installed at regular distances. However, such cellular corridors with high power sites in short distance intervals are not sustainable due to the infrastructure power consumption. To render railway connectivity more sustainable, we propose to deploy fewer high-power radio units with intermediate low-power support repeater nodes. We show that these repeaters consume only 5 % of the energy of a regular cell site and help to maintain the same data capacity in the trains. In a further step, we introduce a sleep mode for the repeater nodes that enables autonomous solar powering and even eases installation because no cables to the relays are needed.

description: We consider the emergence of a non-Fermi liquid fixed point in a two-dimensional metal, at the onset of a quantum phase transition from a Fermi liquid state to an incommensurate charge density wave (CDW) ordered phase. The momentum of the CDW boson is centred at the wavevector $ \boldsymbol{ \mathcal Q} $, which connects a single pair of antipodal points on the Fermi surface with antiparallel tangent vectors. We employ the dimensional regularization technique in which the co-dimension of the Fermi surface is extended to a generic value, while keeping the dimension of the Fermi surface itself fixed at one. Although the system is strongly coupled at dimension $d=2$, the interactions become marginal at the upper critical dimension $d=d_c$, whose value is found to be $ 5/2$. Using a controlled perturbative expansion in the parameter $ε= d_c - d $, we compute the critical exponents of the stable infrared fixed point characterizing the quantum critical point. The scalings of the original theory are determined by setting $ε=1/2$, where the fermion self-energy is seen to scale with the frequency with a fractional power law of $2/3$, which is the telltale signature of a typical non-Fermi liquid phase.

There are four ways to implement this symmetry in the fermion sector, leading to models known as Type-I, Type-II, Lepton-Specific and Flipped. In the latter three models, there is a priori the surprising possibility that the 125 GeV Higgs boson couples mostly as a scalar to top quarks, while it couples mostly as a pseudoscalar to bottom quarks. This ``maximal'' scenario was still possible with the data available in 2017. Since then, there have been more data on the 125 GeV Higgs boson, direct searches for CP-violation in angular correlations of $τ$-leptons produced in Higgs boson decays, new results on the electron electric dipole moment, new constraints from LHC searches for additional Higgs bosons and new results on $b\to s γ$ transitions. Highlighting the crucial importance of the physics results of LHC's Run 2, we combine all these experiments and show that the ``maximal'' scenario is now excluded in all models. Still, one can have a pseudoscalar component in $h τ\barτ$ couplings in the Lepton-Specific case as large as $87\%$ of the scalar component for all mass orderings of the neutral scalar bosons.

THE MAIN STAGES OF THE DEVELOPMENT OF THE BUKHARA PEOPLE'S SOVIET REPUBLIC
Creators: name: Jurayev, Sulton
Publisher: name: Zenodo
Year: 2025

description: The Bukhara People's Soviet Republic (BPSR) was a short-lived but significant political entity that emerged in Central Asia following the collapse of the Emirate of Bukhara in 1920. This thesis examines the main stages of the BPSR’s development from its revolutionary formation through its governance and legal transformations to its eventual integration into the Soviet Union. Drawing on primary sources (including the 1921 BPSR Constitution) and scholarly analyses, we chronologically outline the BPSR’s evolution: the revolutionary overthrow of the emirate and establishment of a People’s Republic, the formation of governmental institutions and initial reforms, the adoption of a unique constitution permitting limited private property and broadening political participation, the challenges of governance amid civil conflict (notably the Basmachi revolt), and the republic’s transition into a Soviet Socialist Republic leading to its voluntary dissolution in 1924.

description: We theoretically investigate high-harmonic generation (HHG) in honeycomb-lattice graphene models when subjected to a DC electric field. By integrating the quantum master equation with the Boltzmann equation, we develop a numerical method to compute laser-driven dynamics in many-electron lattice systems under DC electric current. The method enables us to treat both the weak-laser (perturbative) and intense-laser (nonperturbative) regimes in a unified way, accounting for the experimentally inevitable dissipation effects. From it, we obtain the HHG spectra and analyze their dependence on laser frequency, laser intensity, laser-field direction, and DC current strength. We show that the dynamical and static symmetries are partially broken by a DC current or staggered potential term, and such symmetry breakings drastically change the shape of the HHG spectra, especially in terms of the presence or absence of $(2n+1)$th-, $2n$th-, or $3n$th-order harmonics ($n\in \mathbb Z$). The laser intensity, frequency, and polarization are also shown to affect the shape of the HHG spectra. Our findings indicate that HHG spectra in conducting electron systems can be quantitatively or qualitatively controlled by tuning various external parameters, and DC electric current is used as such an efficient parameter.

description: Video-based point cloud compression (V-PCC) has been an emerging compression technology that projects the 3D point cloud into a 2D plane and uses high efficiency video coding (HEVC) to encode the projected 2D videos (geometry video and color video). In this work, we propose a rate control algorithm for the all-intra (AI) configuration of V-PCC. Specifically, based on the quality-dependency existing in the projected videos, we develop an optimization formulation to allocate target bits between the geometry video and the color video. Furthermore, we design a two-pass method for HEVC to adapt to the new characteristics of projected videos, which significantly improves the accuracy of rate control. Experimental results demonstrate that our algorithm outperforms V-PCC without rate control in R-D performance with just 0.43% bitrate error.

Emergent Transition from Radial Foraging to Tree-like Raiding Patterns Induced by Complete Following for Pheromone

description: Abstract: Among ants that show complex and diverse collective actions, army ants are known to raid prey in groups. It has been confirmed that the characteristic pattern in a swarm raid of army antschanges from radial to tree-like with time. There are some simulation studies focusing only on the emergence of tree-like patterns. However, the models adopted in their simulations cannot represent the transition of patterns from radial to tree-like observed in the real world. In this study, we propose an army ant model with a modification of the model adopted by Solé et al. and clarify the conditions of the emergence of the transition. From the experimental simulation results of our model, we deduce that the simple modification of the Solé model can move individuals in eight directions, but it is not enough to express multidirectional to unidirectional convergence. Additionally, our simulation experiments showed that for the pattern transition from radial to tree-like, it is necessary for the individuals to keep moving forward until they get food, and for the returning individual to completely follow the pheromone.

Keywords: army ant model, radial foraging pattern, tree-like raiding pattern, swarm raid, complete following for pheromone.

Tidal synchronization trapping in stars and planets with convective envelopes

description: Tidal torques can alter the spins of tidally interacting stars and planets, usually over shorter timescales than the tidal damping of orbital separations or eccentricities. Simple tidal models predict that, in eccentric binary or planetary systems, rotation periods will evolve toward a "pseudosynchronous" ratio with the orbital period. However, this prediction does not account for "inertial" waves that are present in stars or gaseous planets with (i) convective envelopes and (ii) even very slow rotation. We demonstrate that tidal driving of inertial oscillations in eccentric systems generically produces a network of stable "synchronization traps" at ratios of orbital to rotation period that are simple to predict but can deviate significantly from pseudosynchronization. The mechanism underlying spin synchronization trapping is similar to tidal resonance locking, involving a balance between torques that is maintained automatically by the scaling of inertial mode frequencies with the rotation rate. In contrast with many resonance locking scenarios, however, the torque balance required for synchronization trapping need not drive mode amplitudes to nonlinearity. Synchronization traps may provide an explanation for low-mass stars and hot Jupiters with observed rotation rates that deviate from pseudosynchronous or synchronous expectations.
