description: This paper continues the Wu-Shamai-Verdu program [3] on characterizing the degrees of freedom (DoF) of interference channels (ICs) through Renyi information dimension. Specifically, we find a single-letter formula for the DoF of vector ICs, encompassing multiple-input multiple-output (MIMO) ICs, time- and/or frequency-selective ICs, and combinations thereof, as well as scalar ICs as considered in [3]. The DoF-formula we obtain lower-bounds the DoF of all channels--with respect to the choice of the channel matrix--and upper-bounds the DoF of almost all channels. It applies to a large class of noise distributions, and its proof is based on an extension of a result by Guionnet and Shlyakthenko [3] to the vector case in combination with the Ruzsa triangle inequality for differential entropy introduced by Kontoyiannis and Madiman [4]. As in scalar ICs, achieving full DoF requires the use of singular input distributions. Strikingly, in the vector case it suffices to enforce singularity on the joint distribution of each individual transmit vector. This can be realized through signaling in subspaces of the ambient signal space, which is in accordance with the idea of interference alignment, and, most importantly, allows the scalar entries of the transmit vectors to have non-singular distributions. The DoF-formula for vector ICs we obtain enables a unified treatment of "classical" interference alignment a la Cadambe and Jafar [5], and Maddah-Ali et al. [6], and the number-theoretic schemes proposed in [7], [8]. Moreover, it allows to calculate the DoF achieved by new signaling schemes for vector ICs. We furthermore recover the result by Cadambe and Jafar on the non-separability of parallel ICs [9] and we show that almost all parallel ICs are separable in terms of DoF. Finally, our results apply to complex vector ICs, thereby extending the main findings of [2] to the complex case.

Geometry of the faithfulness assumption in causal inference

description: Many algorithms for inferring causality rely heavily on the faithfulness assumption. The main justification for imposing this assumption is that the set of unfaithful distributions has Lebesgue measure zero, since it can be seen as a collection of hypersurfaces in a hypercube. However, due to sampling error the faithfulness condition alone is not sufficient for statistical estimation, and strong-faithfulness has been proposed and assumed to achieve uniform or high-dimensional consistency. In contrast to the plain faithfulness assumption, the set of distributions that is not strong-faithful has nonzero Lebesgue measure and in fact, can be surprisingly large as we show in this paper. We study the strong-faithfulness condition from a geometric and combinatorial point of view and give upper and lower bounds on the Lebesgue measure of strong-faithful distributions for various classes of directed acyclic graphs. Our results imply fundamental limitations for the PC-algorithm and potentially also for other algorithms based on partial correlation testing in the Gaussian case.

description: We revise primordial black holes (PBHs) production in the axion-curvaton model, in light of recent developments in the computation of their abundance accounting for non-gaussianities (NGs) in the curvature perturbation up to all orders. We find that NGs intrinsically generated in such scenarios have a relevant impact on the phenomenology associated to PBHs and, in particular, on the relation between the abundance and the signal of second-order gravitational waves. We show that this model could explain both the totality of dark matter in the asteroid mass range and the tentative signal reported by the NANOGrav and IPTA collaborations in the nano-Hz frequency range. En route, we provide a new, explicit computation of the power spectrum of curvature perturbations going beyond the sudden-decay approximation.

description: Motivated by genome-wide association studies, we consider a standard linear model with one additional random effect in situations where many predictors have been collected on the same subjects and each predictor is analyzed separately. Three novel contributions are (1) a transformation between the linear and log-odds scales which is accurate for the important genetic case of small effect sizes; (2) a likelihood-maximization algorithm that is an order of magnitude faster than the previously published approaches; and (3) efficient methods for computing marginal likelihoods which allow Bayesian model comparison. The methodology has been successfully applied to a large-scale association study of multiple sclerosis including over 20,000 individuals and 500,000 genetic variants.

Pseudorapidity density of charged particles in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV

Subjects: subject: Nuclear Experiment (nucl-ex)

description: The charged-particle pseudorapidity density measured over 4 units of pseudorapidity in non-single-diffractive (NSD) p-Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}} = 5.02$ TeV is presented. The average value at midrapidity is measured to be $16.81 \pm 0.71$ (syst.), which corresponds to $2.14 \pm 0.17$ (syst.) per participating nucleon. This is 16% lower than in NSD pp collisions interpolated to the same collision energy, and 84% higher than in d-Au collisions at $\sqrt{s_{\rm NN}} = 0.2$ TeV. The measured pseudorapidity density in p-Pb collisions is compared to model predictions, and provides new constraints on the description of particle production in high-energy nuclear collisions.

We advocate stochastic control as a finite time and low variance alternative to popular steady-state methods such as stochastic gradient Langevin dynamics. Furthermore, we discuss and adapt the existing theoretical guarantees of this framework and establish connections to already existing VI routines in SDE-based models.

description: Closed-loop chemical recycling provides a solution to the end-of-use problem of synthetic polymers. However, it remains a major challenge to design dynamic bonds, capable of effective bonding and reversible cleaving, for preparing chemically recyclable cross-linked polymers. Herein, we report a dynamic maleic acid tertiary amide bond based upon reversible amidation reaction between maleic anhydrides and secondary amines. This dynamic bond allows for the construction of polymer networks with tailorable and robust mechanical properties, covering strong elastomers with a tensile strength of 22.3 MPa and rigid plastics with a yield strength of 38.3 MPa. Impressively, these robust polymeric materials can be completely depolymerized in an acidic aqueous solution at ambient temperature, leading to efficient monomer recovery with >94% separation yields. Meanwhile, the recovered monomers can be used to remanufacture cross-linked polymeric materials without losing their original mechanical performance. This work unveils a general approach to design polymer networks with tunable mechanical performance and closed-loop recyclability, which will open a new avenue for sustainable polymeric materials.

description: We study a class of nonstandard interactions of the newly discovered 125 GeV Higgs-like resonance that are especially interesting probes of new physics: flavor violating Higgs couplings to leptons and quarks. These interaction can arise in many frameworks of new physics at the electroweak scale such as two Higgs doublet models, extra dimensions, or models of compositeness. We rederive constraints on flavor violating Higgs couplings using data on rare decays, electric and magnetic dipole moments, and meson oscillations. We confirm that flavor violating Higgs boson decays to leptons can be sizeable with, e.g., h -> tau mu and h -> tau e branching ratios of order 10% perfectly allowed by low energy constraints. We estimate the current LHC limits on h -> tau mu and h -> tau e decays by recasting existing searches for the SM Higgs in the tau-tau channel and find that these bounds are already stronger than those from rare tau decays. We also show that these limits can be improved significantly with dedicated searches and we outline a possible search strategy. Flavor violating Higgs decays therefore present an opportunity for discovery of new physics which in some cases may be easier to access experimentally than flavor conserving deviations from the Standard Model Higgs framework.

description: We investigate the structure of the medium formed in heavy ion collisions using three different models: the Color String Percolation Model (CSPM), the Core-Shell-Color String Percolation Model (CSCSPM), and the Color Glass Condensate (CGC) framework. We analyze the radial distribution function of the transverse representation of color flux tubes in each model to determine the medium's structure. Our results indicate that the CSPM behaves as an ideal gas, while the CSCSPM exhibits a structural phase transition from a gas-like to a liquid-like structure. Additionally, our analysis of the CGC framework suggests that it produces systems that behave like interacting gases for AuAu central collisions at RHIC energies and liquid-like structures for PbPb central collisions at LHC energies.

description: Episodic accretion is a low-mass pre-main sequence phenomenon characterized by sudden outbursts of enhanced accretion. These objects are classified into two: protostars with elevated levels of accretion that lasts for decades or more, called FUors, and protostars with shorter and repetitive bursts, called EXors. HBC 494 is a FUor object embedded in the Orion Molecular Cloud. Earlier Atacama Large (sub-)Millimeter Array (ALMA) continuum observations showed an asymmetry in the disk at 0.''2 resolution. Here, we present follow-up observations at ~0.''03, resolving the system into two components: HBC 494 N (primary) and HBC 494 S (secondary). No circumbinary disk was detected. Both disks are resolved with a projected separation of ~0.''18 (75 au). Their projected dimensions are 84+/-1.8 x 66.9+/-1.5 mas for HBC 494 N and 64.6+/-2.5 x 46.0+/-1.9 mas for HBC 494 S. The disks are almost aligned and with similar inclinations. The observations show that the primary is ~5 times brighter/more massive and ~2 times bigger than the secondary. We notice that the northern component has a similar mass to the FUors, while the southern has to EXors. The HBC 494 disks show individual sizes that are smaller than single eruptive YSOs. In this work, we also report 12CO, 13CO, and C18O molecular line observations. At large scale, the 12CO emission shows bipolar outflows, while the 13CO and C18O maps show a rotating and infalling envelope around the system. At a smaller scale, the 12CO and 13CO moment zero maps show cavities within the continuum disks' area, which may indicate continuum over-subtraction or slow-moving jets and chemical destruction along the line-of-sight.

description: Mit dem Traktor beim Pflügen außerhalb der Furche zu fahren, ist eine aus der Sicht der Bodenschonung schon lange erhobene Forderung. Der überwiegende Teil der Landwirte interessierte sich bisher für diese Möglichkeit erst, wenn die Reifen des Traktors beim Fahren in der Furche den gepflügten Boden zu stark rückverdichteten. Da dies bei kleineren Pflugaggregaten selten der Fall war und die Schwierigkeiten des Onlandpflügens mit abnehmender Arbeitsbreite zunehmen, beschränkte sich das Onlandpflügen bislang auf die größeren Pflüge. Untersuchungen an einem Dreischarpflug unter ebenen Bedingungen auf sandigen Böden belegen, dass heute die technischen Probleme des Onlandpflügens mit Pflügen geringer Arbeitsbreite weitestgehend gelöst sind und eine Anwendung in der Praxis für die genannten Bedingungen zu empfehlen ist.

description: ObjectivesWe developed a guided self-help intervention (Supporting Weight Management during COVID-19, "SWiM-C") to support adults with overweight or obesity in their weight management during the COVID-19 pandemic. This parallel, two-group trial (ISRCTN12107048) evaluated the effect of SWiM-C on weight and determinants of weight management over twelve months.MethodsParticipants (≥18 years, body-mass-index ≥25 kg/m2) were randomised to the SWiM-C intervention or to a standard advice group (unblinded). Participants completed online questionnaires at baseline, four months, and twelve months. The primary outcome was change in self-reported weight from baseline to twelve months; secondary outcomes were eating behaviour (uncontrolled eating, emotional eating, cognitive restraint of food intake), experiential avoidance, depression, anxiety, stress, wellbeing and physical activity.InterventionsSWiM-C is based on acceptance and commitment therapy (ACT). Participants had access to an online web platform with 12 weekly modules and email and telephone contact with a trained, non-specialist coach. Standard advice was a leaflet on managing weight and mood during the COVID-19 pandemic.Results388 participants were randomised (SWiM-C: n = 192, standard advice: n = 196). The baseline-adjusted difference in weight change between SWiM-C (n = 119) and standard advice (n = 147) was -0.81 kg (95% CI: -2.24 to 0.61 kg). SWiM-C participants reported a reduction in experiential avoidance (-2.45 [scale:10-70], 95% CI: -4.75 to -0.15), uncontrolled eating (-3.36 [scale: 0-100], 95% CI: -5.66 to -1.06), and emotional eating (-4.14 [scale:0-100], 95% CI: -7.25 to -1.02) and an increase in physical activity (8.96 [MET-min/week], 95% CI: 0.29 to 17.62) compared to standard advice participants. We found no evidence of an effect on remaining outcomes. No adverse events/side effects were reported.ConclusionsWhilst we were unable to conclude that the intervention had an effect on weight, SWiM-C improved eating behaviours, experiential avoidance and physical activity. Further refinement of the intervention is necessary to ensure meaningful effects on weight prior to implementation in practice.Trial registration numberISRCTN 12107048.

description: We demonstrate how to use feedback to control the internal states of trapped coherent ensembles of two-level atoms, and to protect a superposition state against the decoherence induced by a collective noise. Our feedback scheme is based on weak optical measurements with negligible back-action and coherent microwave manipulations. The efficiency of the feedback system is studied for a simple binary noise model and characterized in terms of the trade-off between information retrieval and destructivity from the optical probe. We also demonstrate the correction of more general types of collective noise. This technique can be used for the operation of atomic interferometers beyond the standard Ramsey scheme, opening the way towards improved atomic sensors.

description: This report describes the results of 10 test shipments of naked-pack iceberg lettuce shipped by highway trailer during the warm summer months. On arrival at eastern markets, lettuce in boxes that were loaded directly on the floor averaged 4.6°F (2.6°C) warmer than lettuce in boxes that were loaded on racks that raised the lettuce about 4 inches (10.1 cm) above the truck floor. The temperature of lettuce loaded against trailer sidewalls that had recessed vertical grooves was about 2°F (1.1 °C) cooler than the temperature of lettuce loaded against sidewalls that were flat. This study also included an enumeration of the various features of 623 randomly selected trailers at lettuce loading docks in central California in 1979. Most had flat sidewalls, wide canvas air-delivery chutes, front bulkheads, and extruded aluminum grooved floors. Most of the trailers were not precooled before loading.

description: Eine energiesparende Zerkleinerung von Restholz zu Hackschnitzeln für eine energetische Nutzung erfordert die zielgerichtete Gestaltung der Schneidpaarung Messerkeil-Gegenschneide. ln einer speziellen Versuchseinrichtung sind der Schnittvorgang und die antriebswirksamen Kräfte am Hackermesser analysiert worden. Die Kräfte und somit das Antriebsmoment nehmen erwartungsgemäß zu, wenn die Hackstücklänge steigt. Ein zügiger Schnittvorgang führt nur bedingt zu geringeren Schnittwiderständen, jedoch zu höherem Energieaufwand. Der spezifische Energieaufwand, bezogen auf die zerkleinerte Masse, sinkt auf Werte unter 50 %, wenn die Hackstücklänge von 1 cm auf 5 cm erhöht wird.

description: 早产是围生医学中的一个重要、复杂而又常见的妊娠并发症，因其围生儿发病率、病死率和后遗症较足月者显著升高而成为一个世界性的卫生问题。世界卫生组织将早产明确定义为在37孕周或<259d妊娠终止者，但没有规定底线，我国指妊娠满28周至不满37周间分娩者。早产在全球的发病率为9.6%,每年有超过100万的早产新生儿死亡。在中国，每年有超过1600万的早产儿，是全球第二大的早产儿人群国家。尽管早产的发病率高，但是其发病机制仍然不清楚。因此，了解早产的致病机理和识别其生物标志物，对与我国预防早产发生有着重要意义。 研究显示，正常怀孕是一种低强度的炎症反应，但是早产患者由于受到感染、炎症反应加强等各种刺激，使得生产提前发生。近来，有证据显示，在整个的怀孕过程中炎症反应是由一系列的内源活性物质所诱导的，在早产的炎症反应过程中，这些物质在不同时间空间进行释放。虽然免疫激活被假设是一个重要的步骤，但在近来的早产的多组学研究中，在炎症引起的通路中并没有发现特定的细胞因子、生物标记物等。另有证据表明，自发早产患者的膜完整性及羊水代谢物可用来测定是否有感染／炎症存在，以用来评估早产的风险，但是收集羊水属于侵入式取样，会增加流产的风险，使得筛查的风险也增高，所以这个研究方法的实际可行性不高。相反，外周血样本更加适合用于孕产妇代谢物分析以预测早产风险，从而帮助诊断和预防早产的发生。本研究探索早产和足月分娩孕妇，孕期血浆脂质组和代谢组之间的差异，以寻找早产早诊早预测的生物标志物。

description: Kuranishi's fundamental result (1962) associates to any compact complex manifold $X_0$ a finite-dimensional analytic space which has to be thought of as a local moduli space of complex structures close to $X_0$. In this paper, we give an analogous statement for Levi-flat CR manifolds fibering properly over the circle by associating to any such $\mathcal X_0$ the loop space of a finite-dimensional analytic space which serves as a local moduli space of CR structures close to $\mathcal X_0$. We then develop in this context a Kodaira-Spencer deformation theory making clear the likenesses as well as the differences with the classical case. The article ends with applications and examples.

description: This presentation explores how emerging Fourth Industrial Revolution (4IR) technologies—such as artificial intelligence (AI), virtual reality (VR), and quantum computing—are transforming artistic practice. The study investigates how these advanced digital tools influence cultural production, from ideation to dissemination.

The argument traces the historical evolution of creative cognition theories, including Guilford’s Divergent Thinking model (1950), the Geneplore Model (1992), and modern frameworks like Process Modification (2020). A central case study follows the journey of Polish painter Roman Lipski, who transitioned from traditional landscape painting to AI-assisted abstraction. Collaborating with data scientist Florian Dohmann, Lipski utilized Generative Adversarial Networks (GAN) and Quantum Blur technology to iterate new visual forms rapidly, redefining his artistic identity.

The presentation also reflects on the aesthetic implications of these technological interventions—how they affect the artist’s creative voice, audience reception, and the collaborative nature of contemporary artmaking. Butler concludes by highlighting how 4IR tools accelerate artistic innovation while simultaneously raising questions about the future of human creativity in an increasingly digitized world.
A Deduction from Dirac Sea Model

description: Whether the Dirac sea model is right is verifiable. Assuming the Dirac sea is a physical reality, we have one imagination that a negative energy particle(s) in the sea and a usual positive energy particle(s) will form a neutral atom. The features of the atom can be studied using the nonrelativistic reduction of the Bethe-Salpeter equation, especially for a two body system. This work is dedicated to discuss the bound state of spin-0 and spin-$\frac{\displaystyle 1}{\displaystyle 2}$ constituents. The study shows that an atom consisting of a negative energy particle $(e^-$ or $hc)$ and a positive energy particle $(u\overline{d}$ or $hc)$ has some features of a neutrino, such as spin, lepton number and oscillation. One deduction is that if the atom is a real particle, an atom $X$ consisting of two negative energy particles and a nucleus with double charges exists in nature, which can be observed in Strangeonium, Charmonium and Bottomonium decays $[s\overline{s}]$, $[c\overline{c}]$ and $[b\overline{b}]\rightarrow X π^-π^- e^+e^+~+~hc$ with $X$ invisible at KLOE, CLEOc, BESIII, Belle and BaBar.

On the geodesic hypothesis in general relativity

description: In this paper, we give a rigorous derivation of Einstein's geodesic hypothesis in general relativity. We use scaling stable solitons for nonlinear wave equations to approximate the test particle. Given a vacuum spacetime $([0, T]\times\mathbb{R}^3, h)$, we consider the scalar field coupled Einstein equations. For all sufficiently small $ε$ and $δ\leq ε^q$, $q>1$, where $δ$, $ε$ are the amplitude and size of the particle, we show the existence of solution $([0, T]\times\mathbb{R}^3, g, ϕ^ε)$ to the coupled Einstein equations with the property that the energy of the particle $ϕ^ε$ is concentrated along a timelike geodesic. Moreover, the gravitational field produced by $ϕ^ε$ is negligibly small in $C^1$, that is, the spacetime metric $g$ is $C^1$ close to $h$. These results generalize those obtained by D. Stuart.

description: BaRuO3 having five different crystal structures has been synthesized by varying the pressure while sintering. Contrary to the other phases being nonmagnetic, the cubic perovskite phase synthesized recently shows an itinerant ferromagnetic character. We investigated this ferromagnetic BaRuO3 using first principles calculations. A few van Hove singularities appear around the Fermi energy, causing unusually high magnetovolume effects of $ΔM/Δa$ ~ 4.3 $μ_B$/Åas well as a Stoner instability [IN(0) ~ 1.2]. At the optimized lattice parameter a, the magnetic moment M is 1.01 $μ_B$ in the local spin density approximation. When spin-orbit coupling is included, the topologies of some Fermi surfaces are altered, and the net moment is reduced by 10% to a value very close to the experimentally observed value of ~ 0.8 $μ_B$. Our results indicate that this ferromagnetism is induced by the Stoner instability, but the combined effects of the p-d hybridization, the magnetovolume, and the spin-orbit coupling determine the net moment. In addition, we briefly discuss the results of the tight-binding Wannier function technique.

description: Durch die Reduzierung der Sämengen bei der Drillsaat gewinnt das Gleichmaß der Kornlängsabstände immer mehr an Bedeutung. Während die Kornabstände bei Einzelkornsägeräten mit ausreichender Genauigkeit durch Lichtschranken vermessen werden können, muss bei Drillmaschinen aufgrund der hohen Kornfrequenz und der damit einhergehenden Häufung gleichzeitig fallender Körner ein erheblicher Messfehler in Kauf genommen werden. Aus diesem Grund wurde ein Optosensor entwickelt, mit welchem durch Einzelabfrage der Empfängerdioden der genaue Fallort der Körner lokalisiert werden kann. Dadurch werden auch gleichzeitig fallende Körner separat erfasst. Der Messfehler des Optosensors beträgt selbst bei hohen Kornfrequenzen nicht mehr als 2 %.

description: Die meisten Ackerflächen weisen eine heterogene Struktur hinsichtlich Bodenart, Nährstoffvorrat oder Wasserversorgung auf. Dennoch werden in der Regel Düngermenge und Aussaatstärke während der Ausbringung unverändert konstant gehalten. Eine Anpassung auf die tatsächlichen Gegebenheiten erfolgt nicht. Die einfache Positionsbestimmung mithilfe der Satellitenortung (DGPS) bietet nun die Möglichkeit, in Verbindung mit einer detaillierten Vorplanung auf dem PC, auf standortspezifische Gegebenheiten zu reagieren. Durch die intelligente Verknüpfung von Betriebsdaten und maschinenspezifischen Funktionen ist eine optimale Umsetzung der Applikationskarte möglich.

description: From behavioral sciences to biology to quantum mechanics, one encounters situations where (i) a system outputs several random variables in response to several inputs, (ii) for each of these responses only some of the inputs may "directly" influence them, but (iii) other inputs provide a "context" for this response by influencing its probabilistic relations to other responses. These contextual influences are very different, say, in classical kinetic theory and in the entanglement paradigm of quantum mechanics, which are traditionally interpreted as representing different forms of physical determinism. One can mathematically construct systems with other types of contextuality, whether or not empirically realizable: those that form special cases of the classical type, those that fall between the classical and quantum ones, and those that violate the quantum type. We show how one can quantify and classify all logically possible contextual influences by studying various sets of probabilistic couplings, i.e., sets of joint distributions imposed on random outputs recorded at different (mutually incompatible) values of inputs.
