description: In order to study the reason phylloxera (Daktulosphaira vitifolia Fitch) feeding on roots leads to decreased plant productivity, the uptake and distribution of 13C photosynthates and 15N in the grape vine 'Wuhe 8612' in response to phylloxera infestation were investigated. Phylloxera and grapevines cocultivated in pots were treated with 13CO2 and 15N-urea. The plant weight, nitrogen concentration and accumulation, 15N utilization efficiency, Nitrogen derived from fertilizer (Ndff%), and carbon isotope ratio (δ13C) of different organs were measured. Phylloxera infestation significantly reduced grape weight, shoot length, and N concentration and accumulation in different organs, whereas it increased the ratio between N content of the of roots and above-ground organs. Phylloxera infestation reduced leaf and root nitrogen 15N utilization efficiency, by 24 % and 14 %, respectively compared to controls. Labeled leaves of infested plants took up rather more 13C and 15N and exported a substantial amount of these nutrients to roots. Labeled roots took up rather more 15N and exported a small amount of these nutrients to upper leaves. This study found that phylloxera infestation reduced 13C and 15N uptake in leaves and roots, but increased N and photosynthates, which were mostly distributed to the roots, but also to the upper leaves. These factors together led to weak grape vine growth.

description: The aims of this study were to achieve correct cultivar classification of leaf samples by using phyllometric parameters to determine the performance of parameters applied as the discriminant criteria and to determine the minimal number of leaf parameters needed to accurately classify leaf samples within cultivars. Seventy-nine phyllometric parameters were measured/calculated on 360 leaf samples from eleven grapevine cultivars, gathered during several years, from different growing conditions and with some differences in the sampling methods applied. Stepwise discriminant analysis was used to rank the phyllometric parameters according to their efficiency in the discrimination of cultivars. A series of discriminant analyses was performed with successive introduction of new parameters as discriminatory elements until 100 % correct classification of leaf samples into the correct cultivar was achieved. This was achieved using only the seven highest ranking phyllometric parameters from the stepwise discriminant analysis. Additionally, canonical discriminant analysis was performed to evaluate the differences between cultivars in the same parameters. This study represents a model for analysis of the efficiency of different ampelometric parameters for discrimination of V. vinifera cultivars.

description: The zero-shot effectiveness of neural retrieval models is often evaluated on the BEIR benchmark -- a combination of different IR evaluation datasets. Interestingly, previous studies found that particularly on the BEIR subset Touché 2020, an argument retrieval task, neural retrieval models are considerably less effective than BM25. Still, so far, no further investigation has been conducted on what makes argument retrieval so "special". To more deeply analyze the respective potential limits of neural retrieval models, we run a reproducibility study on the Touché 2020 data. In our study, we focus on two experiments: (i) a black-box evaluation (i.e., no model retraining), incorporating a theoretical exploration using retrieval axioms, and (ii) a data denoising evaluation involving post-hoc relevance judgments. Our black-box evaluation reveals an inherent bias of neural models towards retrieving short passages from the Touché 2020 data, and we also find that quite a few of the neural models' results are unjudged in the Touché 2020 data. As many of the short Touché passages are not argumentative and thus non-relevant per se, and as the missing judgments complicate fair comparison, we denoise the Touché 2020 data by excluding very short passages (less than 20 words) and by augmenting the unjudged data with post-hoc judgments following the Touché guidelines. On the denoised data, the effectiveness of the neural models improves by up to 0.52 in nDCG@10, but BM25 is still more effective. Our code and the augmented Touché 2020 dataset are available at \url{https://github.com/castorini/touche-error-analysis}.

description: Agent based distributed manufacturing control and scheduling systems are subsets of new manufacturing systems. Multi agent systems (MAS) not only drive design and engineering control solutions but also influence flexibility, agility, and re-configurability, which makes MASs a better centralized systems than its traditional counterparts. However, implementation of all MASs in the real factories are timely, also extremely costly. A simulation environment that would allow independent development and testing of the services and business processes of the related manufacturing hardware is needed. This paper presents the design and implementation of a userfriendly simulation platform for multi agent based manufacturing control systems by considering the shop floor level. The proposed simulation platform can simulate the software level of the factory by considering the hardware level of the mentioned factory. An example of the simulation platform is presented for a flexible manufacturing system, which is located in EMU CIM lab.
The Scientific Foundation for inertia
Creators: name: Wilcox, Clyde Jermaine
Publisher: name: Zenodo
Year: 2025

description: Today I bring the first Foundation for inertia!!!

This paper introduces the Triadic Exchange Model, a novel, mechanistic theory of inertia grounded in electromagnetic principles. Unlike classical and quantum vacuum models, this framework proposes that inertia arises from dynamic impedance between external field pressure (FP) and an internal electromagnetic structure called Magnetic Information Density (MID). This internal coding, unique to each mass, determines resistance to acceleration through a structured EM exchange, not stochastic vacuum drag.

 

The model offers clear testable pathways, including plasma-based lag detection and EM field modulation experiments, and presents a unified lens bridging classical mechanics, field theory, and potential quantum interpretations. By offering an internal structure to inertia, this work establishes a true physical foundation for a force long defined only by its effects.

description: Tandem repeats in proteins identification, classification and curation is a complex process that requires manual processing from experts, processing power and time. There are recent and relevant advances applying machine learning for protein structure prediction and repeat classification that are useful for this process. However, no service contemplates required databases and software to supplement researching on repeat proteins. In this publication we present Daisy, an integrated repeat protein curation web service. This service can process Protein Data Bank (PDB) and the AlphaFold Database entries for tandem repeats identification. In addition, it uses an algorithm to search a sequence against a library of Pfam hidden Markov model (HMM). Repeat classifications are associated with the identified families through RepeatsDB. This prediction is considered for enhancing the ReUPred algorithm execution and hastening the repeat units identification process. The service can also operate every associated PDB and AlphaFold structure with a UniProt proteome registry. Availability: The Daisy web service is freely accessible at daisy.bioinformatica.org.

D3.1 Technical Requirements, Architecture and Testing Plan
Creators: name: HARPOCRATES Consortium
Publisher: name: Zenodo
Year: 2024

description: Project HARPOCRATES investigates technologies, tools and solutions for secure and privacy-preserving data processing and sharing. We use two demonstrators to validate the security solutions developed in the project. The demonstrators are (i) threat intelligence generation and sharing between local authorities, exploring exchange of threat intelligence information between two regional governments in EU member states (Italy and Spain) and (ii) collaborative use of Machine Learning in Sleep Medicine, exploring exchange of sleep research data between three research institutions located in three EU member states (Finland, France, and Germany). Solutions developed in the project will be applied to these demonstrators and subsequently presented. This document contains the technical requirements solicited in close collaboration with the demonstrator partners, architecture of the HARPOCRATES solution toolbox containing the enablers developed by the technical partners, as well as the testing plan for the solutions. The two demonstrators described in this document represent vastly different technological prerequisites, data models and operational constraints. This is reflected both in their overall descriptions, as well as in the threat models, requirements, and target operations. Their detailed description in this document is an important early contribution of the project. They highlight the stringent requirements towards privacy-preserving solutions based on practicalchallenges, as well challenge to various implicit and explicit assumptions. 

The document also describes the enablers to be developed in HARPOCRATES to address the demonstrator requirements. The enablers described in this document reflect the variety of complementary approaches that need to be combined and tailored according to the specific context and peculiarities of the application use cases.

This document reconciles the wide range of demonstrator requirements with the limitations of the state-of-the art technologies used in the enablers. It also serves as a roadmap for the remainder of the project in the implementation of the HARPOCRATES solution toolbox and implementation of the demonstrators.

description: An engaging first programming class (CS1) often inspires students’ passion for computer science (CS). However, the evidence in the literature suggests that the average CS1 classes are anything but engaging for many students. The performance of CS compared to other science, technology, engineering, and mathematics (STEM) courses in international student engagement surveys seems to substantiate CS1 failure, attrition rates, and lack of diversity in most CS classes. Meanwhile, for its simplicity in introducing programming to beginners, primary and secondary schools use Scratch, an educational programming environment developed by the Massachusetts Institute of Technology, USA. For the same reason, higher institutions now include some forms of Scratch instruction in CS1.The question remains, to what extent is Scratch engaging, especially for students in higher education? This study addressed this gap by observing college computer science students exposed to a constructionist Scratch programming pedagogy.

description: The extreme outer Galaxy (EOG), which we define as the region of the Milky Way with a galactocentric radius of more than 18 kpc, provides an excellent opportunity to study star formation in an environment significantly different from that in the solar neighborhood because of its lower metallicity and lower gas density. We carried out near- and mid-infrared (NIR and MIR) imaging observations toward two star-forming clusters located in the EOG using JWST NIRCam and MIRI with nine filters: F115W, F150W, F200W, F350W, F405N, F444W, F770W, F1280W, and F2100W. In this paper, we present an overview of the observations, data reduction, and initial results. The NIR sensitivity is approximately 10--80 times better than our previous observation with the Subaru 8.2 m telescope. Accordingly, the mass detection limit reaches to about 0.01--0.05 $M_\odot$, which is about 10 times better than the previous observations. At MIR wavelengths, the high sensitivity and resolution data enable us to resolve individual young stellar objects in such a distant region for the first time. The mass detection limit at MIR F770W filter reaches about 0.1--0.3 $M_\odot$. With these new observations, we have identified components of the clusters that previous surveys did not detect, including class 0 candidates, outflow/jet components, and distinctive nebular structures. These data will enable us to investigate the properties of star formation in the EOG at the same depth of detail as previous observations of star formation in the solar neighborhood.

Beyond Senate Bill 3: How to Achieve Environmental Flows in Texas Under Prior Appropriation

Publisher: name: Texas Water Journal
Year: 2022

description: In 2007, the 80th Texas Legislature enacted Senate Bill 3 on the 140th and last day of session. This bill was the third far-reaching piece of water legislation after Senate Bill 1 passed in 1997 and Senate Billl 2 passed in 2001. Collectively, these bills changed how Texas plans for future water needs, regulates groundwater, promotes conservation, studies the need for environmental flows balanced with population needs, and establishes environmental flow standards for Texas’ rivers, bays, and estuaries. Senate Bill 3 created a process through which scientists, stakeholders, and the Texas Commission on Environmental Quality set environmental flow standards. Over 12 years have passed since Senate Bill 3 became law, allowing us to consider the efficacy of the enabling legislation and the resulting rules. In short, identifying and securing water for the environment has been difficult due to little if any unallocated water in the state’s river basins and limitations in Senate Bill 3 and Texas Water Code. We identified seven options for the stakeholders and the state to consider to increase the protection of environmental flows while respecting private property rights: (1) protecting water-right owners that participate in forbearance agreements from cancellation, (2) pursuing cancellations and affirming abandonments, (3) requiring that cancelled or abandoned water be set-aside to meet environmental flow standards, (4) modernizing how surface-water use and diversions are tracked, (5) requiring water rights holders to demonstrate the pursuit of other water supplies before suspending environmental flows, (6) studying ways how environmental flows can co-exist and be protected within a prior-appropriation system, and (7) studying how dedications of water under existing water rights can be considered for tax credit or deductions so as to further incentivize transactions for environmental benefit. If implemented, these options could allow Texas and Texans to more closely achieve the desired outcomes hoped for from Senate Bill 3.

description: This paper studies the organization and decision-making process of the Ministry of State Security’s (MSS) regarding cyber-operations through three hypotheses. The first hypothesis explores the MSS's centralized goal-setting mechanism. It examines the MSS’ structure from the State Council down to regional bureaus, focusing on intelligence collection pipelines. It also evaluates how national priorities and intelligence requirements are shaped, utilizing broad and vague terminologies rooted in traditional slogan politics, and how cyber-operations at the APT level align with strategic plans such as the 14th Five Year Plan and Made in China 2025. The second hypothesis challenges the first by suggesting a decentralized execution of cyber-operations within the MSS, through the varied command relationships among hacker groups, front companies, and MSS authorities under the contractor model. By studying the operational autonomy of groups like APT41 and the control dynamics in cases like APT40, the paper assesses the decentralization in cyber operations and explores the nature of relationships—whether competitive or coordinated—among different hacking groups. The third hypothesis argues that the MSS has priority access to zero-day vulnerabilities and influences their disclosure, thereby gaining strategic advantages in cyber-operations. This hypothesis is examined through the lens of the 2021 Regulations on the Management of Network Product Security Vulnerabilities, which has facilitated the MSS's capability to exploit these vulnerabilities.

description: We investigate numerical methods for wave equations in $n+2$ spacetime dimensions, written in spherical coordinates, decomposed in spherical harmonics on $S^n$, and finite-differenced in the remaining coordinates $r$ and $t$. Such an approach is useful when the full physical problem has spherical symmetry, for perturbation theory about a spherical background, or in the presence of boundaries with spherical topology. The key numerical difficulty arises from lower-order $1/r$ terms at the origin $r=0$. As a toy model for this, we consider the flat space linear wave equation in the form $\dotπ=ψ'+pψ/r$, $\dotψ=π'$, where $p=2l+n$, and $l$ is the leading spherical harmonic index. We propose a class of summation by parts (SBP) finite differencing methods that conserve a discrete energy up to boundary terms, thus guaranteeing stability and convergence in the energy norm. We explicitly construct SBP schemes that are second and fourth-order accurate at interior points and the symmetry boundary $r=0$, and first and second-order accurate at the outer boundary $r=R$.

Our preferred model is based on equivariant infinite loop space theory applied to elementary categorical data. It recasts equivariant stable homotopy theory in terms of point-set level categories of G-spans and nonequivariant spectra. We also give a more topologically grounded model based on equivariant Atiyah duality.

As a consequence, we establish a structure theory for module categories over deformation quantizations that mirrors, at a higher categorical level, the Bialynicki-Birula stratification of a variety with an action of the multiplicative group. The resulting categorical cell decomposition provides an algebro-geometric parallel to the structure of Fukaya categories of Weinstein manifolds. From it, we derive concrete consequences for invariants such as K-theory and Hochschild homology of module categories of interest in geometric representation theory.

description: Bell's theorem shows a profound contradiction between local realism and quantum mechanics on the level of statistical predictions. It does not involve directly Einstein-Podolsky-Rosen (EPR) correlations. The paradox of Greenberger-Horne-Zeilinger (GHZ) disproves directly the concept of EPR elements of reality, based on the EPR correlations, in an all-versus-nothing way. A three-qubit experimental demonstration of the GHZ paradox was achieved nearly twenty years ago, and followed by demonstrations for more qubits. Still, the GHZ contradictions underlying the tests can be reduced to three-qubit one. We show an irreducible four-qubit GHZ paradox, and report its experimental demonstration. The reducibility loophole is closed. The bound of a three-setting per party Bell-GHZ inequality is violated by $7σ$. The fidelity of the GHZ state was around $81\%$, and an entanglement witness reveals a violation of the separability threshold by $19σ$.

Here we present and demonstrate a general technique that simplifies the construction of QFT interferometers using both path and polarization modes. On that basis, we first observed the generalized Hong-Ou-Mandel effect with up to four photons. Furthermore, we directly exploited number-path entanglement generated in these QFT interferometers and demonstrated optical phase supersensitivities deterministically.

description: The biological complexity present in Nature has been attributed to a number of processes, here we consider coevolutionary arms races. Previous coevolutionary research has shown that such monotonic progress is possible, but these existing monotonic algorithms employ engineered techniques not likely to have influenced Natural evolution, such as comparisons to archives of historical individuals. We study Markovian coevolution, where the only preserved information is contained within the evolving population itself. In a signaling game from evolutionary game theory we show how parameters of evolutionary dynamics influence the reachability of evolutionary equilibria. We build on these ideas to show how a model of escalation in evolutionary arms races can continue to increase in complexity under finite population dynamics, but is vulnerable to coevolutionary pathologies even at large population sizes. When using a coevolutionary game that incorporates an external environment we find that more complex external environments better facilitate coevolutionary escalation. Finally, this idea is extended to consider how population diversity can play the same role as exogenous environmental complexity by facilitating escalation in 2 models: a minimalist coevolutionary game, and a swarm game. We conclude that competitive coevolution is a productive evolutionary mechanism capable of escalation, and show that both exogenous and endogenous complexity can facilitate the escalation of coevolutionary arms races.

description: We study smooth complex hypersurfaces in direct products of closed hyperbolic Riemann surfaces and give a classification in terms of their fundamental groups. This answers a question of Delzant and Gromov on subvarieties of products of Riemann surfaces in the smooth codimension one case. We also answer Delzant and Gromov's question of which subgroups of a direct product of surface groups are Kähler for two classes: subgroups of direct products of three surface groups; and subgroups arising as kernel of a homomorphism from the product of surface groups to $\mathbb{Z}^3$. These results will be a consequence of answering the more general question of which subgroups of a direct product of surface groups are the image of a homomorphism, which is induced by a holomorphic map, for the same two classes. This provides new constraints on Kähler groups.

description: We investigate the weight distribution of random binary linear codes. For $0<λ<1$ and $n\to\infty$ pick uniformly at random $λn$ vectors in $\mathbb{F}_2^n$ and let $C \le \mathbb{F}_2^n$ be the orthogonal complement of their span. Given $0<γ<1/2$ with $0< λ< h(γ)$ let $X$ be the random variable that counts the number of words in $C$ of Hamming weight $γn$. In this paper we determine the asymptotics of the moments of $X$ of all orders $o(\frac{n}{\log n})$.

description: We develop axiomatics of highest weight categories and quasi-hereditary algebras in order to incorporate two semi-infinite situations which are in Ringel duality with each other; the underlying posets are either upper finite or lower finite. We also consider various more general sorts of stratified categories. In the upper finite cases, we give an alternative characterization of these categories in terms of based quasi-hereditary algebras and based stratified algebras, which are certain locally unital algebras possessing triangular bases.

description: In recent years, there has been a considerable amount of interest in stability of equations and their corresponding groups. Here, we initiate the systematic study of the quantitative aspect of this theory. We develop a novel method, inspired by the Ornstein-Weiss quasi-tiling technique, to prove that abelian groups are polynomially stable with respect to permutations, under the normalized Hamming metrics on the groups $\operatorname{Sym}(n)$. In particular, this means that there exists $D\geq 1$ such that for $A,B\in \operatorname{Sym}(n)$, if $AB$ is $δ$-close to $BA$, then $A$ and $B$ are $ε$-close to a commuting pair of permutations, where $ε\leq O(δ^{1/D})$. We also observe a property-testing reformulation of this result, yielding efficient testers for certain permutation properties.

description: The degenerate Heisenberg category $\mathcal{H}eis_k$ is a strict monoidal category which was originally introduced in the special case $k=-1$ by Khovanov in 2010. Khovanov conjectured that the Grothendieck ring of the additive Karoubi envelope of his category is isomorphic to a certain $\mathbb{Z}$-form for the universal enveloping algebra of the infinite-dimensional Heisenberg Lie algebra specialized at central charge $-1$. We prove this conjecture and extend it to arbitrary central charge $k \in \mathbb{Z}$. We also explain how to categorify the comultiplication (generically).

Morse-Bott cohomology from homological perturbation theory

description: In this paper, we construct cochain complexes generated by the cohomology of critical manifolds in the abstract setup of flow categories for Morse-Bott theories under minimum transversality assumptions. We discuss the relations between different constructions of Morse-Bott theories. In particular, we explain how homological perturbation theory is used in Morse-Bott theories, and both our construction and the cascades construction can be interpreted as applications of homological perturbations. In the presence of group actions, we construct cochain complexes for the equivariant theory. Expected properties like the independence of approximations of classifying spaces and the existence of the action spectral sequence are proven. We carry out our construction for Morse-Bott functions on closed manifolds and prove it recovers the regular cohomology. We outline the project of combining our construction with the polyfold theory.

description: We consider the group of pure welded braids (also known as loop braids) up to (link-)homotopy. The pure welded braid group classically identifies, via the Artin action, with the group of basis-conjugating automorphisms of the free group, also known as the McCool group P $Σ$ n. It has been shown recently that its quotient by the homotopy relation identifies with the group hP $Σ$ n of basis-conjugating automorphisms of the reduced free group. In the present paper, we describe a decomposition of this quotient as an iterated semi-direct product which allows us to solve the Andreadakis problem for this group, and to give a presentation by generators and relations. The Andreadakis equality can be understood, in this context, as a statement about Milnor invariants; a discussion of this question for classical braids up to homotopy is also included.

description: The convex dimension of a $k$-uniform hypergraph is the smallest dimension $d$ for which there is an injective mapping of its vertices into $\mathbb{R}^d$ such that the set of $k$-barycenters of all hyperedges is in convex position. We completely determine the convex dimension of complete $k$-uniform hypergraphs, which settles an open question by Halman, Onn and Rothblum, who solved the problem for complete graphs. We also provide lower and upper bounds for the extremal problem of estimating the maximal number of hyperedges of $k$-uniform hypergraphs on $n$ vertices with convex dimension $d$. To prove these results, we restate them in terms of affine projections that preserve the vertices of the hypersimplex. More generally, we provide a full characterization of the projections that preserve its $i$-dimensional skeleton. In particular, we obtain a hypersimplicial generalization of the linear van Kampen-Flores theorem: for each $n$, $k$ and $i$ we determine onto which dimensions can the $(n,k)$-hypersimplex be linearly projected while preserving its $i$-skeleton. Our results have direct interpretations in terms of $k$-sets and $(i,j)$-partitions, and are closely related to the problem of finding large convexly independent subsets in Minkowski sums of $k$ point sets.

description: We show that Gallager's ensemble of Low-Density Parity Check (LDPC) codes achieves list-decoding capacity with high probability. These are the first graph-based codes shown to have this property. This result opens up a potential avenue towards truly linear-time list-decodable codes that achieve list-decoding capacity.
 Our result on list decoding follows from a much more general result: any $\textit{local}$ property satisfied with high probability by a random linear code is also satisfied with high probability by a random LDPC code from Gallager's distribution. Local properties are properties characterized by the exclusion of small sets of codewords, and include list-decodability, list-recoverability and average-radius list-decodability.
 In order to prove our results on LDPC codes, we establish sharp thresholds for when local properties are satisfied by a random linear code. More precisely, we show that for any local property $\mathcal{P}$, there is some $R^*$ so that random linear codes of rate slightly less than $R^*$ satisfy $\mathcal{P}$ with high probability, while random linear codes of rate slightly more than $R^*$, with high probability, do not. We also give a characterization of the threshold rate $R^*$.

description: In this work we propose a discretization of the second boundary condition for the Monge-Ampere equation arising in geometric optics and optimal transport. The discretization we propose is the natural generalization of the popular Oliker-Prussner method proposed in 1988. For the discretization of the differential operator, we use a discrete analogue of the subdifferential. Existence, unicity and stability of the solutions to the discrete problem are established. Convergence results to the continuous problem are given.

description: Background: Experiments have reported low normal tissue toxicities during FLASH radiation, but the mechanism has not been elaborated. Several hypotheses have been proposed to explain the mechanism. The oxygen depletion hypothesis has been introduced and mostly studied qualitatively. Methods: We present a computational model to describe the time-dependent change of oxygen concentration in the tissue. The kinetic equation of the model is solved numerically using the finite difference method. The model is used to analyze the FLASH effect with the oxygen depletion hypothesis, and the brain tissue is chosen as an example. Results: The oxygen distribution is determined by the oxygen consumption rate of the tissue and the distance between capillaries. The change of oxygen concentration with time after radiation has been found to follow a negative exponential function, and the time constant is determined by the distance between capillaries. When the dose rate is high enough, the same dose results in the same change of oxygen concentration regardless of dose rate. The analysis of FLASH effect in the brain tissue based on this model does not support the explanation of the oxygen depletion hypothesis. Conclusions: The oxygen depletion hypothesis remains controversial because oxygen in most normal tissues cannot be depleted by FLASH radiation according to the mathematical analysis with this model and experiments on the expression and distribution of the hypoxia-inducible factors.
