Brane/flux annihilation in double-throat system

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study the brane/flux annihilation in the double-throat system in which the corresponding cycles of two throats are homologically equivalent. When we put $\overline{\rm D3}$-branes at only one of throat tips, two throats are no longer identical. Then the brane/flux annihilation can be interpreted as the process for reducing the difference between two throat geometries through the transition to the supersymmetric vacuum. To see this, we describe the changes in the amounts of the NSNS 3-form flux supporting the B-cycle contained in two throat regions during the brane/flux annihilation. We also compare our analysis with the recently proposed thraxion scenario, which also describes the inequivalence of two throats caused by the different NSNS 3-form flux distributions in two throat regions.

description: We investigate the interplay of the electronic and structural transition in La$_{0.2}$Sr$_{0.8}$MnO$_{3}$. The transport and specific heat measurements exhibit unusual evolutions and signature of a first order phase transition around 265 K. Mn K-edge extended $x$-ray absorption fine structure results reveal distortion in the MnO$_6$ octahedra even in the cubic phase and a remarkable evolution of the distortion across the phase transition. These results manifest the importance of fluctuations in Mn 3$d$ orbital occupancy and disorder in their electronic properties, which may help in understanding the orbital and spin ordering proposed in these systems.

description: Background: Little is known about the knowledge and use of technology-based interventions (TBIs) by health personnel working in the addiction field across Europe. Methods: An online questionnaire was designed using SurveyMonkey® in order to determine the level of knowledge, use and perceived efficacy of TBIs in substance use disorders (SUDs), among health professionals across six EU Member States: Germany, Italy, UK, France, Poland and the Netherlands. The survey was sent to a convenience sample of 1200 addiction experts. Results: Surveyed participants (311, response rate 26%), had a mean professional addiction experience of 17 years; 23% stated to have good knowledge of TBIs, while 12% use them in their clinical practice. Forty-six percent consider TBIs useful in the treatment of addiction, and 44% foresee a significant increase of them in the future. TBIs were considered important for people facing barriers to accessing treatment (63%) and for providing support outside the formal care settings (60%). Lack of technical support (48%), poor infrastructure and equipment (42%), and lack of digital literacy among health workers (38%) were identified as the main obstacles in the diffusion of TBIs. Conclusions: Knowledge and utilisation of TBIs among health workers in drug addiction field is low. Nevertheless, TBIs are perceived as a possible means of facilitation in providing access to treatment, and as therapeutic tools which will become more important in the future. The need to improve training policies, awareness and attitudes towards TBIs among EU health professionals, working in the field of addiction is paramount.

description: The high accuracy envisaged for future measurements of W-boson production at hadron colliders has to be matched by precise theoretical predictions. We study the impact of electroweak radiative corrections on W-boson production cross sections and differential distributions at the Tevatron and at the LHC. In particular, we include photon-induced processes, which contribute at O(alpha), and leading radiative corrections beyond O(alpha) in the high-energy Sudakov regime and from multi-photon final-state radiation. We furthermore present the calculation of the complete supersymmetric next-to-leading-order electroweak and QCD corrections to W-boson hadroproduction within the MSSM. The supersymmetric corrections turn out to be negligible in the vicinity of the W resonance in general, reaching the percent level only at high lepton transverse momentum and for specific choices of the supersymmetric parameters.

description: We consider the first few virial coefficients of the osmotic pressure, the radius of gyration, the hydrodynamic radius, and the end-to-end distance for a monodisperse polymer solution. We determine the corresponding two-parameter model functions which parametrize the crossover between the good-solvent and the ideal-chain behavior. These results allow us to predict the osmotic pressure and the polymer size in the dilute regime in a large temperature region above the theta-point.

description: Background: There is increasing recognition that the workplace holds potential as an alcohol prevention/intervention setting. However, few robust studies of workplace interventions have been conducted. Research to-date has yielded mixed results. The current study aimed to address this knowledge gap by undertaking a process evaluation of the Workplace Alcohol Harm Reduction Project (WRAHP), a co-produced workplace alcohol intervention. Methods: A process evaluation was embedded within the WRAHP intervention trial. It included site visits (n = 41), site observations (N = 8) and on-site semi-structured key informant interviews (N = 50), conducted over the 3-year evaluation period. Results: A ‘whole-of-workplace’ plus a ‘co-production’ approach during intervention development and implementation contributed to uptake and sustainability. Seven potential barriers or facilitators emerged: (i) attitudes toward alcohol in the workplace, (ii) policy development and awareness, (iii) referral pathways and access to support, (iv) participation and equity: production pressure, (v) participation and equity: language barriers, (vi) communication and (vii) sustainability of the intervention. Conclusions: Embedding a tailored alcohol intervention within a ‘worker-wellbeing’ framework promoted acceptance. This approach enabled barriers to be addressed whilst identifying facilitators of success. These results add to a growing evidence base regarding the value of interventions that target alcohol and support replication of similar co-produced interventions in other workplace settings.
Global firing induced by network disorder in ensembles of active rotators

description: We study the influence of repulsive interactions on an ensemble of coupled excitable rotators. We find that a moderate fraction of repulsive interactions can trigger global firing of the ensemble. The regime of global firing, however, is suppressed in sufficiently large systems if the network of repulsive interactions is fully random, due to self-averaging in its degree distribution. We thus introduce a model of partially random networks with a broad degree distribution, where self-averaging due to size growth is absent. In this case, the regime of global firing persists for large sizes. Our results extend previous work on the constructive effects of diversity in the collective dynamics of complex systems.

description: Precise segmentation and anatomical identification of the vertebrae provides the basis for automatic analysis of the spine, such as detection of vertebral compression fractures or other abnormalities. Most dedicated spine CT and MR scans as well as scans of the chest, abdomen or neck cover only part of the spine. Segmentation and identification should therefore not rely on the visibility of certain vertebrae or a certain number of vertebrae. We propose an iterative instance segmentation approach that uses a fully convolutional neural network to segment and label vertebrae one after the other, independently of the number of visible vertebrae. This instance-by-instance segmentation is enabled by combining the network with a memory component that retains information about already segmented vertebrae. The network iteratively analyzes image patches, using information from both image and memory to search for the next vertebra. To efficiently traverse the image, we include the prior knowledge that the vertebrae are always located next to each other, which is used to follow the vertebral column. This method was evaluated with five diverse datasets, including multiple modalities (CT and MR), various fields of view and coverages of different sections of the spine, and a particularly challenging set of low-dose chest CT scans. The proposed iterative segmentation method compares favorably with state-of-the-art methods and is fast, flexible and generalizable.

We determined the scaling of the torque with Reynolds numbers at various angular velocity ratios (Rotation numbers), and the behaviour of the wall shear stress when varying the Rotation number at high Reynolds numbers. We compare the curves with PIV analysis of the mean flow and show the peculiar role of perfect counterrotation for the emergence of organised large scale structures in the mean part of this very turbulent flow that appear in a smooth and continuous way: the transition resembles a supercritical bifurcation of the secondary mean flow.

description: The effect of 8 MeV energy electron beam radiation at 40, 80 and 120 kGy dosage on surface morphology and thermal properties of lithium perchlorate-doped poly (vinylidene fluoride-co-hexafluoropropylene) polymer electrolyte films have been studied. The field emission scanning electron microscopic image shows small-porous structured morphology for unirradiated film, but it changed drastically into large and deep porous structure as well as the size of spherulites is reduced for 120 kGy confirming the influence of irradiation on morphology. The atomic force microscope reveals the significantly changed surface roughness of unirradiated film from 116.8 to 123.4 nm with a hill-like pattern morphology for 120 kGy confirming the increased amorphousity after irradiation. The thermal study confirmed that the decrease in the melting point of unirradiated film 160.86–155.24°C for 120 kGy doses is attributed to the formation of defects by the chain scissioning process resulting in the degradation of polymer electrolytes at high dose.

Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: A multi-dimension, time-dependent Monte Carlo code is used to compute sample gamma-ray spectra to explore whether unambiguous constraints could be obtained from gamma-ray observations of Type Ia supernovae. Both spherical and aspherical geometries are considered and it is shown that moderate departures from sphericity can produce viewing-angle effects that are at least as significant as those caused by the variation of key parameters in one-dimensional models. Thus gamma-ray data could in principle carry some geometrical information, and caution should be applied when discussing the value of gamma-ray data based only on one-dimensional explosion models. In light of the limited sensitivity of current gamma-ray observatories, the computed theoretical spectra are studied to revisit the issue of whether useful constraints could be obtained for moderately nearby objects. The most useful gamma-ray measurements are likely to be of the light curve and time-dependent hardness ratios, but sensitivity higher than currently available, particularly at relatively hard energies (~2-3 MeV), is desirable.

description: Understanding the origin of accretion and dispersal of protoplanetary disks is fundamental for investigating planet formation. Recent numerical simulations show that launching winds are unavoidable when disks undergo magnetically driven accretion and/or are exposed to external UV radiation. Observations also hint that disk winds are common. We explore how the resulting wind mass loss rate can be used as a probe of both disk accretion and dispersal. As a proof-of-concept study, we focus on magnetocentrifugal winds, MRI (magnetorotational instability) turbulence, and external photoevapotaion. By developing a simple, yet physically motivated disk model and coupling it with simulation results available in the literature, we compute the mass loss rate as a function of external UV flux for each mechanism. We find that different mechanisms lead to different levels of mass loss rate, indicating that the origin of disk accretion and dispersal can be determined, by observing the wind mass loss rate resulting from each mechanism. This determination provides important implications for planet formation. This work thus shows that the ongoing and future observations of the wind mass loss rate for protoplanetary disks are paramount to reliably constrain how protoplanetary disks evolve with time and how planet formation takes place in the disks.

A Fast and Scalable Polyatomic Frank-Wolfe Algorithm for the LASSO

description: We propose a fast and scalable Polyatomic Frank-Wolfe (P-FW) algorithm for the resolution of high-dimensional LASSO regression problems. The latter improves upon traditional Frank-Wolfe methods by considering generalized greedy steps with polyatomic (i.e. linear combinations of multiple atoms) update directions, hence allowing for a more efficient exploration of the search space. To preserve sparsity of the intermediate iterates, we re-optimize the LASSO problem over the set of selected atoms at each iteration. For efficiency reasons, the accuracy of this re-optimization step is relatively low for early iterations and gradually increases with the iteration count. We provide convergence guarantees for our algorithm and validate it in simulated compressed sensing setups. Our experiments reveal that P-FW outperforms state-of-the-art methods in terms of runtime, both for FW methods and optimal first-order proximal gradient methods such as the Fast Iterative Soft-Thresholding Algorithm (FISTA).

description: The extremely luminous supernova SN 2006gy challenges the traditional view that the collapse of a stellar core is the only mechanism by which a massive star makes a supernova, because it seems too luminous by more than a factor of ten. Here we report that the brightest supernovae in the modern Universe arise from collisions between shells of matter ejected by massive stars that undergo an interior instability arising from the production of electron-positron pairs. This "pair instability" leads to explosive burning that is insufficient to unbind the star, but ejects many solar masses of the envelope. After the first explosion, the remaining core contracts and searches for a stable burning state. When the next explosion occurs, several solar masses of material are again ejected, which collide with the earlier ejecta. This collision can radiate 1E50 erg of light, about a factor of ten more than an ordinary supernova. Our model is in good agreement with the observed light curve for SN 2006gy and also shows that some massive stars can produce more than one supernova-like outburst.

Perfect Zero-Knowledge PCPs for #P
Creators: name: Gur, Tom
Publisher: name: Apollo - University of Cambridge Repository
Year: 2025

description: We construct perfect zero-knowledge probabilistically checkable proofs (PZK-PCPs) for every language in #P. This is the first construction of a PZK-PCP for any language outside BPP. Furthermore, unlike previous constructions of (statistical) zero-knowledge PCPs, our construction simultaneously achieves non-adaptivity and zero knowledge against arbitrary (adaptive) polynomial-time malicious verifiers. Our construction consists of a novel masked sumcheck PCP, which uses the combinatorial nullstellen- satz to obtain antisymmetric structure within the hypercube and randomness outside of it. To prove zero knowledge, we introduce the notion of locally simulatable encodings: randomised encodings in which every local view of the encoding can be efficiently sampled given a local view of the message. We show that the code arising from the sumcheck protocol (the Reed–Muller code augmented with subcube sums) admits a locally simulatable encoding. This reduces the algebraic problem of simulating our masked sumcheck to a combinatorial property of antisymmetric functions.

description: We investigate some of the properties and extensions of a dynamic innovation network model recently introduced in \citep{koenig07:_effic_stabil_dynam_innov_networ}. In the model, the set of efficient graphs ranges, depending on the cost for maintaining a link, from the complete graph to the (quasi-) star, varying within a well defined class of graphs. However, the interplay between dynamics on the nodes and topology of the network leads to equilibrium networks which are typically not efficient and are characterized, as observed in empirical studies of R&D networks, by sparseness, presence of clusters and heterogeneity of degree. In this paper, we analyze the relation between the growth rate of the knowledge stock of the agents from R&D collaborations and the properties of the adjacency matrix associated with the network of collaborations. By means of computer simulations we further investigate how the equilibrium network is affected by increasing the evaluation time $τ$ over which agents evaluate whether to maintain a link or not. We show that only if $τ$ is long enough, efficient networks can be obtained by the selfish link formation process of agents, otherwise the equilibrium network is inefficient. This work should assist in building a theoretical framework of R&D networks from which policies can be derived that aim at fostering efficient innovation networks.

description: The Group on Earth Observations (GEO) is transitioning from its previous Engagement Priorities (such as the Sustainable Development Goals and the Paris Agreement) to a new set of Thematic Areas, including Agriculture and Food Security, Water and Land Sustainability, and One Health, among others. This session will specifically focus on the GEO Thematic Area of One Health. 
The objectives of this session are: 
Exploring the evolution of the GEO Infrastructure: The session aims to discuss how GEO's infrastructure can evolve to better support the initiatives and activities within the Thematic Area of One Health. This includes identifying the necessary functionalities, tools, and datasets that should be available within the infrastructure, as well as exploring how GEO's knowledge and services can be organized more effectively. The outcomes of this discussion will be addressed by the GEO Infrastructure Development Task Team (GIDTT), the group responsible for driving the ongoing evolution of the GEO infrastructure. 
Fostering Open Knowledge practices: Another key goal is to explore how best to integrate open knowledge practices within the GEO Thematic Areas. By doing so, participants can ensure that these areas are better equipped to connect, collaborate, reuse, and generate new, innovative insights and knowledge. 
Addressing barriers to Open Knowledge adoption: The session identifid and discussed the main barriers to adopting Open Knowledge practices in GEO's Thematic Areas, with the goal of proposing solutions to overcome these challenges.

Noise-Induced Limitations to the Scalability of Distributed Integral Control

Year: 2018
Subjects: subject: Optimization and Control (math.OC)

description: We study performance limitations of distributed feedback control in large-scale networked dynamical systems. Specifically, we address the question of how the performance of distributed integral control is affected by measurement noise. We consider second-order consensus-like problems modeled over a toric lattice network, and study asymptotic scalings (in network size) of H2 performance metrics that quantify the variance of nodal state fluctuations. While previous studies have shown that distributed integral control fundamentally improves these performance scalings compared to distributed proportional feedback control, our results show that an explicit inclusion of measurement noise leads to the opposite conclusion. The noise's impact on performance is shown to decrease with an increased inter-nodal alignment of the local integral states. However, even though the controller can be tuned for acceptable performance for any given network size, performance will degrade as the network grows, limiting the scalability of any such controller tuning. In particular, the requirement for inter-nodal alignment increases with network size. We show that this in practice implies that large and sparse networks will require any integral control to be centralized, rather than distributed. In this case, the best-achievable performance scaling, which is shown to be that of proportional feedback control, is retrieved.

description: In this paper, we discuss distributed optimization over directed graphs, where doubly-stochastic weights cannot be constructed. Most of the existing algorithms overcome this issue by applying push-sum consensus, which utilizes column-stochastic weights. The formulation of column-stochastic weights requires each agent to know (at least) its out-degree, which may be impractical in e.g., broadcast-based communication protocols. In contrast, we describe FROST (Fast Row-stochastic-Optimization with uncoordinated STep-sizes), an optimization algorithm applicable to directed graphs that does not require the knowledge of out-degrees; the implementation of which is straightforward as each agent locally assigns weights to the incoming information and locally chooses a suitable step-size. We show that FROST converges linearly to the optimal solution for smooth and strongly-convex functions given that the largest step-size is positive and sufficiently small.

description: We provide an affirmative answer to the question posed in the title. Our argument is based on a treatment of the Schroedinger dynamics of the composite of a quantum microsystem, S, and a macroscopic measuring apparatus, I, consisting of N interacting particles. The pointer positions of this apparatus are represented by orthogonal subspaces of its representative Hilbert space that are simultaneous eigenspaces of coarse-grained macroscopic observables. By taking explicit account of their macroscopicality via a large deviation principle, we prove that, for a suitably designed apparatus I, the evolution of the composite (S+I) leads both to the reduction of the wave packet of S and to a one-to-one correspondence between the resultant state of this microsystem and the pointer position of I, up to utterly negligible corrections that decrease exponentially with N.

On the Power of Interactive Proofs for Learning
Creators: name: Gur, Tom
Publisher: name: Apollo - University of Cambridge Repository
Year: 2025

description: We continue the study of doubly-efficient proof systems for verifying agnostic PAC learning, for which we obtain the following results. • We construct an interactive protocol for learning the t largest Fourier characters of a given function f : {0, 1}n → {0, 1} up to an arbitrarily small error, wherein the verifier uses poly(t) random examples. This improves upon the Interactive Goldreich-Levin protocol of [GRSY21], whose sample complexity is poly(t, n). • For agnostically learning the class AC0[2] under the uniform distribution, we build on the work of [CIKK17] and design an interactive protocol, where given a function f : {0, 1}n → {0, 1}, the verifier learns the closest hypothesis up to polylog(n) multiplicative factor, using quasi- polynomially many random examples. In contrast, this class has been notoriously resistant even for constructing realisable learners (without a prover) using random examples. • For agnostically learning k-juntas under the uniform distribution, we obtain an interactive protocol, where the verifier uses O(2k ) random examples to a given function f : {0, 1}n → {0, 1}. Crucially, the sample complexity of the verifier is independent of n. We also show that if we do not insist on doubly-efficient proof systems, then the model becomes trivial. Specifically, we show a protocol for an arbitrary class C of Boolean functions in the distribution-free setting, where the verifier uses O(1) labeled examples to learn f.

description: In this work I demonstrate how to characterize topological phase transitions in BDI symmetry class superconductors (SCs) in 1D, using the recently introduced approach of Berry singularity markers (BSMs). In particular, I apply the BSM method to the celebrated Kitaev chain model, as well as to a variant of it, which contains both nearest and next nearest neighbor equal spin pairings. Depending on the situation, I identify pairs of external fields which can detect the topological charges of the Berry singularities which are responsible for the various topological phase transitions. These pairs of fields consist of either a flux knob which controls the supercurrent flow through the SC, or, strain, combined with a field which can tune the chemical potential of the system. Employing the present BSM approach appears to be within experimental reach for topological nanowire hybrids.

description: [transcription] A Dijon, le 1er mai 1768.

Depuis trois mois mon cher Monsieur une cruelle fluxion s'est jetée sur mes yeux et à peine je commence à m'en sortir. Je regarde comme un augure heureux le peu d'emploi que je fais de mes yeux pour vous écrire. Il y a plus, c'est qu'à peine pendant tout ce temps [...] j'ai cru même vous avoir donné avis de la réception de votre lettre et du livre des marnres d'Arundel que vous avez eu la bonté de me renvoyer qui cependant est arrivée un mois plus tard que vous ne me [fol. 146 v] marquez dans votre lettre, vous deviez bien vous épargner l'embarras et les frais de transport. Je vous avoue que cette exactitude ne m'a pas fait plaisir. Vous n'aviez qu'à me l'adresser tout uniment. Je voudrais bien être à portée d'avoir quelque chose qui vous fit plaisir. Comptez toujours sur un serviteur qui vous est bien dévoué. Monsieur de Ruffé m'a dit qu'il était venu un curieux anglais le voir de votre part. c'est un homme à ce qu'il m'a dit qui était versé dans la connaissance des médailles. Comme tous les antiquaires, nous aurions bien envie d'avoir ici quelque de vos savantes dissertations. Nous sommes esturiens bonis, desaltérez nous, envoyez-moi quelque chose que je lirai de votre part à notre Académie ou que je ferai lire si mes yeux encore me refusent ce service. L'on a fondé ici une académie de dessin et nous avons un professeur assez habile. [fol. 147 r] Depuis huit à dix mois cent cinquante écoliers, peintres ou sculpteurs, ont déjà fait de grands progrès et je donnerai dans le mois d'août trois médailles, une d'or et deux d'argent pour encourager nos jeunes artistes et ce sera à l'académie de Dijon à qui j'ai remis le soin de les distribuer et d'en [...][déchirure] les honneurs. Elle est même donnée sous leurs auspices dans une assemblée publique où l'on distribuera des couronnes avec fanfare. Vous savez que l'éclat fait quelquefois plus d'effet sur les corps que la véritable gloire. Il faut tenter tout pour elle au bien de la patrie. J'ai déjà fait placer dans notre académie dix des plus grands hommes de notre pays et je continuerai le plus longtemps que je pourrais, pour tâcher d'animer nos aiglons, pour s'élever vers le soleil. Eclairez-nous de quelque chose de votre façon. Nous joindrons la reconnaissance à l'estime que méritent vos vertus et ferai mon honneur de me dire toute ma vie avec une amitié respectueuse, mon cher Monsieur, votre très humble et très obéissant serviteur,

Legouz de Gerland

description: The chemical investigation of the leaves and stem bark of Acacia polyacantha (Fabaceae) led to the isolation of a new oleanane-type triterpenoid saponin named polyacanthoside A 1 together with fifteen known compounds. Their structures were established from spectral , mainly HRESIMS, 1D NMR and 2D NMR and by comparison with literature data. The cytotoxicity of compound 1 and the analogues 8 as well as doxorubicin was determined in a panel of 9 cancer cell lines including sensitive and drug resistant phenotypes. Unlike the analogue 8, compound 1 as well as doxorubicin displayed cytotoxic effects in all the 9 tested cancer cell lines with IC50 values ranged from 8.90 μM (towards CCRF-CEM leukemia cells) to 35.21 μM (towards HepG2 hepatocarcinoma cells) for compound 1 and from 0.02 μM (towards CCRF-CEM leukemia cells) to 66.83 μM (against CEM/ADR5000 leukemia cells) for doxorubicin.

description: Salient segmentation aims to segment out attention-grabbing regions, a critical yet challenging task and the foundation of many high-level computer vision applications. It requires semantic-aware grouping of pixels into salient regions and benefits from the utilization of global multi-scale contexts to achieve good local reasoning. Previous works often address it as two-class segmentation problems utilizing complicated multi-step procedures including refinement networks and complex graphical models. We argue that semantic salient segmentation can instead be effectively resolved by reformulating it as a simple yet intuitive pixel-pair based connectivity prediction task. Following the intuition that salient objects can be naturally grouped via semantic-aware connectivity between neighboring pixels, we propose a pure Connectivity Net (ConnNet). ConnNet predicts connectivity probabilities of each pixel with its neighboring pixels by leveraging multi-level cascade contexts embedded in the image and long-range pixel relations. We investigate our approach on two tasks, namely salient object segmentation and salient instance-level segmentation, and illustrate that consistent improvements can be obtained by modeling these tasks as connectivity instead of binary segmentation tasks for a variety of network architectures. We achieve state-of-the-art performance, outperforming or being comparable to existing approaches while reducing inference time due to our less complex approach.

description: We present measurements of the internal state distribution of electrostatically guided formaldehyde. Upon excitation with continuous tunable ultraviolet laser light the molecules dissociate, leading to a decrease in the molecular flux. The population of individual guided states is measured by addressing transitions originating from them. The measured populations of selected states show good agreement with theoretical calculations for different temperatures of the molecule source. The purity of the guided beam as deduced from the entropy of the guided sample using a source temperature of 150K corresponds to that of a thermal ensemble with a temperature of about 30 K.
