description: High-resolution medical images are beneficial for analysis but their acquisition may not always be feasible. Alternatively, high-resolution images can be created from low-resolution acquisitions using conventional upsampling methods, but such methods cannot exploit high-level contextual information contained in the images. Recently, better performing deep-learning based super-resolution methods have been introduced. However, these methods are limited by their supervised character, i.e. they require high-resolution examples for training. Instead, we propose an unsupervised deep learning semantic interpolation approach that synthesizes new intermediate slices from encoded low-resolution examples. To achieve semantically smooth interpolation in through-plane direction, the method exploits the latent space generated by autoencoders. To generate new intermediate slices, latent space encodings of two spatially adjacent slices are combined using their convex combination. Subsequently, the combined encoding is decoded to an intermediate slice. To constrain the model, a notion of semantic similarity is defined for a given dataset. For this, a new loss is introduced that exploits the spatial relationship between slices of the same volume. During training, an existing in-between slice is generated using a convex combination of its neighboring slice encodings. The method was trained and evaluated using publicly available cardiac cine, neonatal brain and adult brain MRI scans. In all evaluations, the new method produces significantly better results in terms of Structural Similarity Index Measure and Peak Signal-to-Noise Ratio (p< 0.001 using one-sided Wilcoxon signed-rank test) than a cubic B-spline interpolation approach. Given the unsupervised nature of the method, high-resolution training data is not required and hence, the method can be readily applied in clinical settings.

description: We set up the effective field theories which describe the SO(5)-invariant picture of the high-Tc cuprates in various regimes. We use these to get quantitative conclusions concerning the size of SO(5)-breaking effects. We consider two applications in detail: (i) the thermodynamic free energy, which describe the phase diagram and critical behaviour, and (ii) the Lagrangian governing the interactions of the pseudo-Goldstone bosons with each other and with the electron quasiparticles deep within the ordered phases. We use these effective theories to obtain predictions for the critical behaviour near the possible bicritical point and the pseudo-Goldstone boson dispersion relations, as well as some preliminary results concerning their contribution to response functions. We systematically identify which predictions are independent of the microscopic details of the underlying electron dynamics, and which depend on more model-dependent assumptions.

EVALUATION AND DEVELOPMENT OF NEW STRATEGY TO ACHIEVE SECURITY AND ENERGY EFFICIENCY IN WIRELESS NETWORK
Creators: name: Vishal Dattana
Publisher: name: Zenodo

description: Wireless Sensor Networks (WSN) consist of a number of nodes. In this type of infrastructureless network, nodes communicate without any centralized control or established infrastructure. One node acts as a router. The routing is a challenging task in WSN due to limited bandwidth and transmission range. Some nodes are fix and some moves quickly in this network and change their path quickly. Several small, inexpensive nodes and sensors are deployed in an open, unprotected environment for long periods of time to communication and collection of sensitive data. The nodes in WSN are supposed to self-organise into a network through wireless communication. The capability of self-configuration and wireless communication allows them to be deployed in an ad-hoc fashion in remote and hostile environments without any existing infrastructure. The figure 1 presents a WSN, where a node is forwarding information to the base station via other nodes.

description: The interaction of charged particles, moving in a uniform magnetic field, with a plane-polarized gravitational wave is considered using the Fokker-Planck- Kolmogorov (FPK) approach. By using a stochasticity criterion, we determine the exact locations in phase space, where resonance overlapping occurs. We investigate the diffusion of orbits around each primary resonance of order (m) by deriving general analytical expressions for an effective diffusion coeficient. A solution to the corresponding diffusion equation (Fokker-Planck equation) for the static case is found. Numerical integration of the full equations of motion and subsequent calculation of the diffusion coefficient verifies the analytical results.

description: Vor ungefähr einhundert Jahren begann die Erforschung der spät- und nacheiszeitlichen Vegetationsgeschichte der Schwäbischen Alb. Demzufolge wurde in der Späteiszeit dieses Mittelgebirge von einer Tundra bedeckt. Erst im Alleröd kam es zu einer Wiederbewaldung mit Kiefern. Auch noch im Präboreal herrschte ein lichter Kiefernwald vor. Im Boreal gelangte dann die Hasel zur Vorherrschaft; Eichen, Linden und Ulmen tauchten auf. Im anschließenden Atlantikum prägten Eichenmischwaldarten mit einer haselreichen Strauchschicht das Landschaftsbild. In dieser Zeit drangen Weiß-Tannen und Fichten auf die Südwestalb vor. Im darauffolgenden Subboreal wurde die Rot-Buche häufigste Baumart. Damals scheinen Nadelgehölze auch am Rande der nordöstlichen Alb aufgetaucht zu sein. Spätestens ab dem Subatlantikum konnte sich der Wald nicht mehr natürlich weiterentwickeln. Vielmehr wurde er in großem Umfang für die Landwirtschaft gerodet oder für andere Zwecke genutzt

description: The purpose of this paper is to investigate a condition \begin{equation*} (C_{p}) \hspace{1cm} α\int_{0}^{u}f(s)ds \leq uf(u)+βu^{p}+γ,\,\,u>0 \end{equation*} for some $α>2$, $γ>0$, and $0\leqβ\leq\frac{\left(α-p\right)λ_{p,0}}{p}$, where $p>1$ and $λ_{p,0}$ is the first eigenvalue of the discrete $p$-Laplacian $Δ_{p,ω}$. Using the above condition, we obtain blow-up solutions to discrete $p$-Laplacian parabolic equations \begin{equation*} \begin{cases} u_{t}\left(x,t\right)=Δ_{p,ω}u\left(x,t\right)+f(u(x,t)), & \left(x,t\right)\in S\times\left(0,+\infty\right), μ(z)\frac{\partial u}{\partial_{p} n}(x,t)+σ(z)|u(x,t)|^{p-2}u(x,t)=0, & \left(x,t\right)\in\partial S\times\left[0,+\infty\right), u\left(x,0\right)=u_{0}\geq0(nontrivial), & x\in S, \end{cases} \end{equation*} on a discrete network $S$, where $\frac{\partial u}{\partial_{p}n}$ denotes the discrete $p$-normal derivative. Here, $μ$ and $σ$ are nonnegative functions on the boundary $\partial S$ of $S$, with $μ(z)+σ(z)>0$, $z\in \partial S$. In fact, it will be seen that the condition $(C_{p})$, the generalized version of the condition $(C)$, improves the conditions known so far.

description: Panel data involving longitudinal measurements of the same set of participants taken over multiple time points is common in studies to understand childhood development and disease modeling. Deep hybrid models that marry the predictive power of neural networks with physical simulators such as differential equations, are starting to drive advances in such applications. The task of modeling not just the observations but the hidden dynamics that are captured by the measurements poses interesting statistical/computational questions. We propose a probabilistic model called ME-NODE to incorporate (fixed + random) mixed effects for analyzing such panel data. We show that our model can be derived using smooth approximations of SDEs provided by the Wong-Zakai theorem. We then derive Evidence Based Lower Bounds for ME-NODE, and develop (efficient) training algorithms using MC based sampling methods and numerical ODE solvers. We demonstrate ME-NODE's utility on tasks spanning the spectrum from simulations and toy data to real longitudinal 3D imaging data from an Alzheimer's disease (AD) study, and study its performance in terms of accuracy of reconstruction for interpolation, uncertainty estimates and personalized prediction.

description: The nonlinear dynamics of charged-surface instability development was investigated for liquid helium far above the critical point. It is found that, if the surface charge completely screens the field above the surface, the equations of three-dimensional (3D) potential motion of a fluid are reduced to the well-known equations describing the 3D Laplacian growth process. The integrability of these equations in 2D geometry allows the analytic description of the free-surface evolution up to the formation of cuspidal singularities at the surface.

description: A melting transition for a system of hard spheres interacting by a repulsive Yukawa potential of DLVO form is studied. To find the location of the phase boundary, we propose a simple theory to calculate the free energies for the coexisting liquid and solid. The free energy for the liquid phase is approximated by a virial expansion. The free energy of the crystalline phase is calculated in the spirit of the Lenard-Jonnes and Devonshire (LJD) theory. The phase boundary is found by equating the pressures and chemical potentials of the coexisting phases. When the approximation leading to the equation of state for the liquid breakes down, the first order transition line is also obtained by applying the Lindemann criterion to the solid phase. Our results are then compared with the Monte Carlo simulations.

description: Esports, short for electronic sports, is a form of competition using video games and has attracted more than 530 million audiences worldwide. To watch esports, people utilize online livestreaming platforms. Recently, a novel interaction method, namely "bullet chats," has been introduced on these platforms. Different from conventional comments, bullet chats are scrolling comments posted by audiences that are synchronized to the livestreaming timeline, enabling audiences to share and communicate their immediate perspectives. The real-time nature of bullet chats, therefore, brings a new perspective to esports analysis. In this paper, we conduct the first empirical study on the bullet chats for esports, focusing on one of the most popular video games, i.e., League of Legends (LoL). Specifically, we collect 21 million bullet chats of LoL from Jan. 2023 to Mar. 2023 across two mainstream platforms (Bilibili and Huya). By performing quantitative analysis, we reveal how the quantity and toxicity of bullet chats distribute (and change) w.r.t. three aspects, i.e., the season, the team, and the match. Our findings show that teams with higher rankings tend to attract a greater quantity of bullet chats, and these chats are often characterized by a higher degree of toxicity. We then utilize topic modeling to identify topics among bullet chats. Interestingly, we find that a considerable portion of topics (14.14% on Bilibili and 22.94% on Huya) discuss themes beyond the game, including genders, entertainment stars, non-esports athletes, and so on. Besides, by further modeling topics on toxic bullet chats, we find hateful speech targeting different social groups, ranging from professions, regions, etc. To the best of our knowledge, this work is the first measurement of bullet chats on esports livestreaming. We believe our study can shed light on esports research from the perspective of bullet chats.

description: Theories with varying gravitational constant $G$ have been studied since long time ago. Among them, the most promising candidates as alternatives of the standard General Relativity are known as scalar-tensor theories. They provide consistent descriptions of the observed universe and arise as the low energy limit of several pictures of unified interactions. Therefore, an increasing interest on the astrophysical consequences of such theories has been sparked over the last few years. In this essay we comment on two methodological approaches to study evolution of astrophysical objects within a varying-$G$ theory, and the particular results we have obtained for boson and white dwarf stars.

description: A computational framework is introduced to detect ransomware through entropy-based perturbation analysis of execution graphs, leveraging deviations in structural entropy to distinguish between benign and malicious behaviors. The proposed approach of ransomware detection models system execution as a dynamic graph, where nodes and edges encapsulate program interactions, enabling the identification of ransomware-induced anomalies. Entropy variations of ransomware, captured over successive execution intervals, quantify behavioral deviations, facilitating an entropy-based divergence scoring mechanism. The experimental evaluation demonstrated that the method achieves high accuracy in identifying ransomware variants, including LockBit, Conti, and REvil, while maintaining a controlled false positive rate. The robustness of the approach was further examined through ablation studies, highlighting the contributions of entropy estimation, graph feature extraction, and divergence scoring in ransomware detection. Comparative assessments against traditional methodologies, including signature-based and heuristic approaches, underscored the advantages of structural entropy analysis in detecting previously unseen ransomware strains. Computational efficiency of ransomware detection was also assessed, demonstrating that the framework remains viable for real-time deployment without imposing significant overhead on system resources. The findings reinforce the need for entropy-based analysis as an effective tool in combating ransomware threats, particularly against techniques designed to evade conventional detection mechanisms. The broader implications of entropy-driven anomaly detection suggest potential applications beyond ransomware identification, extending to a variety of cybersecurity challenges where structural deviations signal malicious intent.

description: The advection of passive tracers in a system of 4 identical point vortices is studied when the motion of the vortices is chaotic. The phenomenon of vortex-pairing has been observed and statistics of the pairing time is computed. The distribution exhibits a power-law tail with exponent $\sim 3.6$ implying finite average pairing time. This exponents is in agreement with its computed analytical estimate of 3.5. Tracer motion is studied for a chosen initial condition of the vortex system. Accessible phase space is investigated. The size of the cores around the vortices is well approximated by the minimum inter-vortex distance and stickiness to these cores is observed. We investigate the origin of stickiness which we link to the phenomenon of vortex pairing and jumps of tracers between cores. Motion within the core is considered and fluctuations are shown to scale with tracer-vortex distance $r$ as $r^{6}$. No outward or inward diffusion of tracers are observed. This investigation allows the separation of the accessible phase space in four distinct regions, each with its own specific properties: the region within the cores, the reunion of the periphery of all cores, the region where vortex motion is restricted and finally the far-field region. We speculate that the stickiness to the cores induced by vortex-pairings influences the long-time behavior of tracers and their anomalous diffusion.

description: The introduction of TEI P5 in 2007 was accompanied by efforts of mapping contents of TEI documents to high level conceptual models like CIDOC CRM. They focused on prosopographical information connecting the textual content with index metadata. Moreover, a flexible use of the  element was implemented, allowing for ontology-like thesauri which can be referred to by pointers from an edition. While these mechanisms for named entities and terms enable powerful indexing, little attention so far has been given to formalizing the ways of dealing with editorial and documentary typologies which are used in attributes like e.g. @type, @function and @reason. These typologies refer to document types, textual and editorial phenomena, the processes of text production and text redaction and similar categories of concepts which characterize the text itself rather than external entities referred to by the textual content. Attributes like @type do not permit the use of pointers to formal conceptual definitions as their expected data type is teidata.enumerated, not URI pointers (although the  element in ODD specifications could map different XML components to formal URIs externally). This paper presents the attempt made at the Heidelberg University Library to enable in TEI documents pointers to definitions of editorial phenomena administrated in a OWL ontology (“heiEDITIONS Concepts”) in order to replace teidata.enumerated attributes with URI pointer mechanisms. This strategy makes use of a few TEI attributes like @ana whose data type is teidata.pointer and some additional pointer attributes provided by a schema extension. A “private URI scheme” stated in the TEI header allows the use of abbreviated URI forms. The goal of this institutional strategy is not only a standardization of the TEI encoding adopted by in-house edition projects and cooperative endeavours but also a transparency in documentary and editorial terminology used in TEI code.

description: We investigate the existence of invariantly defined quasi-local hypersurfaces in the Kastor-Traschen solution containing $N$ charge-equal-to-mass black holes. These hypersurfaces are characterized by the vanishing of particular curvature invariants, known as Cartan invariants, which are generated using the frame approach. The Cartan invariants of interest describe the expansion of the outgoing and ingoing null vectors belonging to the invariant null frame arising from the Cartan-Karlhede algorithm. We show that the evolution of the hypersurfaces surrounding the black holes depends on an upper-bound on the total mass for the case of two and three equal mass black holes. We discuss the results in the context of the geometric horizon conjectures.

description: Im Laufe der vergangenen 15 Jahre wurden die Flechten im Gemeindegebiet von Lauda-Königshofen erfasst. Von großem Interesse waren die noch verbliebenen Reste an naturnah strukturierten Landschaftselementen wie alte Wälder, Hecken, Streuobstbestände, Trockenrasen, anstehende Gesteinsformationen und Lesesteinwälle. Insgesamt wurden bisher 206 Arten gefunden. Die stark gefährdeten Arten Anaptychia ciliaris, Gyalecta fagicola, Lecanora allophana, Lecanora varia, Placidium squamulosum, Ramalina fraxinea, Toninia sedifolia und Usnea glabrescens sind nur mehr mit sehr wenigen Exemplaren vertreten. Äußerst selten in Deutschland ist auch Xanthoparmelia perrugata. Bedingt durch den erhöhten Eintrag von Stickstoffverbindungen stieg der Anteil an nitrophytischen, baumbewohnenden Arten stark an. Für die Verbesserung der Lebensbedingungen der bodenbewohnenden Flechten wird eine Schaffung von Pufferzonen um die bestehenden Schutzgebiete von Trockenrasen empfohlen. Der Weiterbestand der seltenen baumbewohnenden Arten kann durch die Einrichtung von Naturwaldreservaten gewährleistet werden. Neu für die Flechtenflora des Taubertales sind: Acarospora impressula, Arthonia dispersa, Aspicilia simoensis, Bacidia rubella, Bilimbia sabuletorum, Calicium glaucellum, Calicium quercinum, Callome multipartita, Caloplaca aurantia, Caloplaca flavescens, Catillaria chalybeia, Catillaria detractula, Cladonia chlorophaea, Cladonia pocillum, Cladonia polydactyla, Cladonia rangiformis, Clauzadea metzleri, Coenogonium pineti, Flavoparmelia soredians, Hypocenomyce caradocensis, Hypogymnia farinacea, Lathagrium cristatum, Lecania cyrtella, Lecania cyrtellina, Lecania naegelii, Lecanora allophana, Lecanora intumescens, Lecanora subcarpinea, Lecidella euphorea, Lecidella scabra, Lepraria finkii, Lepraria jackii, Loxospora elatina, Micarea coppinsii, Micarea denigrata, Micarea misella, Ochrolechia androgyna, Opegrapha vulgata, Peltigera membranacea, Peltigera neckeri, Pertusaria coccodes, Phaeophyscia endophoenicea, Placynthiella icmalea, Placynthiella oligotropha, Placynthiella uliginosa, Porpidia cinereoatra, Protoblastenia rupestris, Protoparmelia hypotremella, Pseudevernia furfuracea var. ceratea, Punctelia jeckeri, Rhizocarpon geographicum subsp. geographicum, Rinodina pyrina, Sarcogyne regularis, Scytinium pulvinatum, Strangospora pinicola, Toninia physaroides, Trapelia glebulosa, Trapeliopsis granulosa, Xanthoparmelia perrugata.

description: We report on the design and performance of a velocity map imaging (VMI) spectrometer optimized for experiments using high-intensity extreme ultraviolet (XUV) sources such as laser-driven high-order harmonic generation (HHG) sources and free-electron lasers (FELs). Typically exhibiting low repetition rates and high single-shot count rates, such~experiments do not easily lend themselves to coincident detection of photo-electrons and -ions. In order to obtain molecular frame or reaction channel-specific information, one has to rely on other correlation techniques, such as covariant detection schemes. Our device allows for combining different photo-electron and -ion detection modes for covariance analysis. We present the expected performance in the different detection modes and present the first results using an intense high-order harmonic generation (HHG) source.

Dispersity-Driven Melting Transition in Two Dimensional Solids

description: We perform extensive simulations of $10^4$ Lennard-Jones particles to study the effect of particle size dispersity on the thermodynamic stability of two-dimensional solids. We find a novel phase diagram in the dispersity-density parameter space. We observe that for large values of the density there is a threshold value of the size dispersity above which the solid melts to a liquid along a line of first order phase transitions. For smaller values of density, our results are consistent with the presence of an intermediate hexatic phase. Further, these findings support the possibility of a multicritical point in the dispersity-density parameter space.

Soft colloids for complex interfacial assemblies

Publisher: name: arXiv
Year: 2022
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: The design of complex materials and the formation of specific patterns often arise from the properties of the individual building blocks. In this respect, colloidal systems offer a unique opportunity because nowadays they can be synthesized in the laboratory with many different shapes and features. Hence, an appropriate choice of the particle characteristics makes it possible to generate macroscopic structures with desired properties. The versatility of colloids can also be explored in two dimensions, using liquid-liquid or air-liquid interfaces as privileged substrates where they can adsorb and self-assemble. Besides being innovative model systems for fundamental studies, the great interest of the scientific community is also technological and applicative, since colloidal-scale surface patterns are very promising for example in photonics or biosensing. In a recent study published in PNAS, Menath and coworkers combine these elements and exploit core-shell colloids, consisting of a silica core and a soft, non-crosslinked polymer shell, to make an important step forward in controlling the assembly of complex structures at an interface.

description: There is a notion of non-commutative Lie algebra called "Leibniz algebra", which is characterized by the condition: left bracketing is a derivation. The purpose of this article is to introduce and study a new notion of algebra, called "associative dialgebra", which is, to the Leibniz algebras, what associative algebras are to Lie algebras. An associative dialgebra is a vector space equipped with two associative operations satisfying three more conditions. For instance, any differential associative algebra gives rise to a dialgebra. In this article we construct and study a (co)homology theory for associative dialgebras. The surprizing fact, in the construction of the chain complex, is the appearance of the combinatorics of planar binary trees (grafting and nesting). The principal result about this homology theory is its vanishing on free associative dialgebras. The Koszul dual (in the sense of Ginzburg and Kapranov) of the operad of associative dialgebras is the operad of "dendriform algebras". The dendriform algebras are characterized by two operations satisfying three linear conditions. The sum of these two operations defines a new operation which is associative. The free dendriform algebra can be described in terms of planar binary trees. As a consequence we give an explicitly description of strong homotopy associative dialgebras. This paper is part of a long-standing project whose ultimate aim is to study periodicity phenomenons in algebraic K-theory, as explained in ``Overview on Leibniz algebras, dialgebras and their homology".

Conductance Fluctuations of Generic Billiards: Fractal or Isolated?

description: We study the signatures of a classical mixed phase space for open quantum systems. We find the scaling of the break time up to which quantum mechanics mimics the classical staying probability and derive the distribution of resonance widths. Based on these results we explain why for mixed systems two types of conductance fluctuat ions were found: quantum mechanics divides the hierarchically structured chaotic component of phase space into two parts - one yields fractal conductance fluctuations while the other causes isolated resonances. In general, both types appear together, but on different energy scales.

description: A satisfactory theory of quantum gravity may necessitate a drastic modification of our perception of space-time, by giving it a foamy structure at distances comparable to the Planck length. It is argued in this essay that the experimental detection of such structures may be a realistic possibility in the foreseeable future. After a brief review of different theoretical approaches to quantum gravity and the relationships between them, we discuss various possible experimental tests of the quantum nature of space-time. Observations of photons from distant astrophysical sources such as Gamma-Ray Bursters and laboratory experiments on neutral kaon decays may be sensitive to quantum-gravitational effects if they are only minimally suppressed. Experimental limits from the Whipple Observatory and the CPLEAR Collaboration are already probing close to the Planck scale, and significant increases in sensitivity are feasible.
