description: We discuss astrophysical implications of $κ$-Minkowski space-time, in which there appears space-time noncommutativity. We first derive a velocity formula for particles based on the motion of a wave packet. The result is that a massless particle moves at a constant speed as in the usual Minkowski space-time, which implies that an arrival time analysis by $γ$-rays from Markarian (Mk) 421 does not exclude space-time noncommutativity. Based on this observation, we analyze reaction processes in $κ$-Minkowski space-time which are related to the puzzling detections of extremely high-energy cosmic rays above the Greisen-Zatsepin-Kuzmin cutoff and of high-energy ($\sim$20 TeV) $γ$-rays from Mk 501.

description: Only forty days after Governor Phillip's First Fleet entered Port Jackson on 26th January 1788 to found the first British settlement in the South Pacific, a second such settlement was established on Norfolk Island. The island lay 905 nautical miles to the east northeast, at 29 degrees south latitude, of what was to become the town of Sydney. From 6th March 1788 the island has been occupied continuously excepting for an eleven year period of abandonment from 1814 to 1825. In its early days it played an important part in the social, economic and administrative history of the colony of New South Wales. Later, from the mid nineteenth century to the period of World War 11, it slumbered in comparative quiet under the occupancy of the "Pitcairners", the descendants of the mutineers of KMS Bounty and their Tahitian consorts. Since 1945 improved communications have brought the island more into the forefront of Australian and world events to the extent that now, in 1976, the many facets of the island, its constitutional future, the welfare of its people, its economy and the retention of its numerous and varied natural attributes, present problems to which there are no quick or easy solutions.

description: With the increasing scale of antenna arrays in wideband millimeter-wave (mmWave) communications, the physical propagation delays of electromagnetic waves traveling across the whole array will become large and comparable to the time-domain sample period, which is known as the spatial-wideband effect. In this case, different subcarriers in an orthogonal frequency division multiplexing (OFDM) system will "see" distinct angles of arrival (AoAs) for the same path. This effect is known as beam squint, resulting from the spatial-wideband effect, and makes the approaches based on the conventional multiple-input multiple-output (MIMO) model, such as channel estimation and precoding, inapplicable. After discussing the relationship between beam squint and the spatial-wideband effect, we propose a channel estimation scheme for frequency-division duplex (FDD) mmWave massive MIMO-OFDM systems with hybrid analog/digital precoding, which takes the beam squint effect into consideration. A super-resolution compressed sensing approach is developed to extract the frequency-insensitive parameters of each uplink channel path, i.e., the AoA and the time delay, and the frequency-sensitive parameter, i.e., the complex channel gain. With the help of the reciprocity of these frequency-insensitive parameters in FDD systems, the downlink channel estimation can be greatly simplified, where only limited pilots are needed to obtain downlink complex gains and reconstruct downlink channels. Furthermore, the uplink and downlink channel covariance matrices can be constructed from these frequency-insensitive channel parameters rather than through a long-term average, which enables the minimum mean-squared error (MMSE) channel estimation to further enhance performance. Numerical results demonstrate the superiority of the proposed scheme over the conventional methods in mmWave communications.

description: In this paper, we propose a state-of-the-art video denoising algorithm based on a convolutional neural network architecture. Previous neural network based approaches to video denoising have been unsuccessful as their performance cannot compete with the performance of patch-based methods. However, our approach outperforms other patch-based competitors with significantly lower computing times. In contrast to other existing neural network denoisers, our algorithm exhibits several desirable properties such as a small memory footprint, and the ability to handle a wide range of noise levels with a single network model. The combination between its denoising performance and lower computational load makes this algorithm attractive for practical denoising applications. We compare our method with different state-of-art algorithms, both visually and with respect to objective quality metrics. The experiments show that our algorithm compares favorably to other state-of-art methods. Video examples, code and models are publicly available at \url{https://github.com/m-tassano/dvdnet}.

Eccentric Minidisks in Accreting Binaries

description: We show that gas disks around the components of an orbiting binary system (so-called minidisks) may be susceptible to a resonant instability which causes the minidisks to become significantly eccentric. Eccentricity is injected by, and also induces, regular impacts between the minidisks at roughly the orbital period of the binary. Such eccentric minidisks are seen in vertically integrated, two-dimensional simulations of a circular, equal-mass binary accreting from a circumbinary gas disk with a $Γ$-law equation of state. Minidisk eccentricity is suppressed by the use of an isothermal equation of state. However, the instability still operates, and can be revealed in a minimal disk-binary simulation by removing the circumbinary disk, and feeding the minidisks from the component positions. Minidisk eccentricity is also suppressed when the gravitational softening length is large ($\gtrsim 4\%$ of the binary semi-major axis), suggesting that its absence could be an artifact of widely adopted numerical approximations; a follow-up study in three dimensions with well-resolved, geometrically thin minidisks (aspect ratios $\lesssim 0.02$) may be needed to assess whether eccentric minidisks can occur in real astrophysical environments. If they can, the electromagnetic signature may be important for discriminating between binary and single black hole scenarios for quasi-periodic oscillations in active galactic nuclei; in turn, this might aid in targeted searches with pulsar timing arrays for individual supermassive black hole binary sources of low-frequency gravitational waves.

On future asymptotics of polarized Gowdy T^3-models

description: Gowdy's model of cosmological spacetimes is a much investigated subject in classical and quantum gravity. Depending on spatial topology recollapsing as well as expanding models are known. Several analytic tools were used in order to clarify singular behaviour in this class of spacetimes. Here we investigate the structure of a certain subclass, the polarized Gowdy models with spatial T^3-topology, in the large. The asymptotics for general solutions of the dynamical equation for one of the gravitational degrees of freedom plays a key role while the asymptotic behaviour of the remaining metric function is a result of solving the Hamiltonian constraint equation. Using both we are able to prove (future) geodesic completeness in all spacetimes of this type.

Metal-enriched Pair-instability supernovae: Effects of rotation

description: In this paper we revisit metal-enriched rotating pair instability supernovae (PISNe) models for metallicities consistent with the Small Magellanic Cloud (SMC), the Large Magellanic Cloud (LMC) and 0.1$Z_\odot$. By calculating multiple models, we intend to clarify mass ranges and the ejected $^{56}$Ni masses from the PISNe, and mass loss histories for progenitors. We find the choice of the Wolf-Rayet (WR) mass-loss rates are important and we adopt the recently proposed rate of Sander & Vink (2020), which covers the mass ranges for PISNe progenitors. We show that slow rotation lowers the PISN range due to the increase in core mass by rotational mixing. On the other hand, if we assume typical rotation speed for observed OB stars, the mass loss increase becomes more significant and the final stellar masses are smaller than non-rotating models. As a result, typical mass range for bright SNe, with $^{56}$Ni mass more than 10${ M}_\odot$ for such fast rotating models are more than 400, 350 ${ M}_\odot$, for LMC and 0.1$Z_\odot$ metallicities, respectively. It is interesting that, unlike previous works, we find Oxygen rich progenitors for most cases. This O-rich progenitor may be consistent with the recently identified PISN candidate SN2018ibb. He-rich progenitors are seen only for relatively dim and metal poor ($Z \lesssim 0.1 Z_\odot$) PISNe. We also discuss the black hole mass gap for metal-enriched PISNe, and show that the upperbound for the gap is lower than in the Pop III case.

description: We consider classical and quantum dynamics of a free particle in de Sitter's space-times with different topologies to see what happens to space-time singularities of removable type in quantum theory. We find analytic solution of the classical dynamics. The quantum dynamics is solved by finding an essentially self-adjoint representation of the algebra of observables integrable to the unitary representations of the symmetry group of each considered gravitational system. The dynamics of a massless particle is obtained in the zero-mass limit of the massive case. Our results indicate that taking account of global properties of space-time enables quantization of particle dynamics in all considered cases.

description: We discuss and prove a theorem which asserts that any n-dimensional semi-Riemannian manifold can be locally embedded in a (n+1)-dimensional space with a non-degenerate Ricci tensor which is equal, up to a local analytic diffeomorphism, to the Ricci tensor of an arbitrary specified space. This may be regarded as a further extension of the Campbell-Magaard theorem. We highlight the significance of embedding theorems of increasing degrees of generality in the context of higher dimensional spacetimes theories and illustrate the new theorem by establishing the embedding of a general class of Ricci-flat spacetimes.

description: We extend the branch point twist field approach for the calculation of entanglement entropies to time-dependent problems in 1+1-dimensional massive quantum field theories. We focus on the simplest example: a mass quench in the Ising field theory from initial mass $m_0$ to final mass $m$. The main analytical results are obtained from a perturbative expansion of the twist field one-point function in the post-quench quasi-particle basis. The expected linear growth of the Rényi entropies at large times $mt\gg 1$ emerges from a perturbative calculation at second order. We also show that the Rényi and von Neumann entropies, in infinite volume, contain subleading oscillatory contributions of frequency $2m$ and amplitude proportional to $(mt)^{-3/2}$. The oscillatory terms are correctly predicted by an alternative perturbation series, in the pre-quench quasi-particle basis, which we also discuss. A comparison to lattice numerical calculations carried out on an Ising chain in the scaling limit shows very good agreement with the quantum field theory predictions. We also find evidence of clustering of twist field correlators which implies that the entanglement entropies are proportional to the number of subsystem boundary points.

description: The investigation of the dynamical universality classes of quantum systems is an important, and rather less explored, aspect of non-equilibrium physics. In this work, considering the out-of-equilibrium dynamics of spinless fermions in a one-dimensional quasiperiodic model with and without a periodic driving, we report the existence of the dynamical one-parameter based Family-Vicsek (FV) scaling of the "quantum surface-roughness" associated with the particle-number fluctuations. In absence of periodic driving, the model is interestingly shown to host a subdiffusive critical phase separated by two subdiffusive critical lines and a triple point from other phases. An analysis of the fate of critical phase in the presence of (inter-phase) driving indicates that the critical phase is quite fragile and has a tendency to get absorbed into the delocalized or localized regime depending on the driving parameters. Furthermore, periodic driving can conspire to show quantum Kardar-Parisi-Zhang (KPZ)-like superdiffusive dynamical behavior, which seems to have no classical counterpart. We further construct an effective Floquet Hamiltonian, which qualitatively captures this feature occurring in the driven model

description: Localized or propagating Majorana boundary modes are the key feature of topological superconductors. They are rare in naturally-occurring compounds, but the tailored manipulation of quantum matter offers opportunities for their realization. Specifically, lattices of Yu-Shiba-Rusinov bound states $-$ Shiba lattices $-$ that arise when magnetic adatoms are placed on the surface of a conventional superconductor can be used to create topological bands within the superconducting gap of the substrate. Here, using scanning tunnelling microscopy to create and probe adatom lattices with single atom precision we reveal two signatures consistent with the realization of two types of mirror symmetry protected topological superconductors. The first has edge modes as well as higher-order corner states, and the second has symmetry-protected bulk nodal points. In principle, their topological character and boundary modes should be protected by the spatial symmetries of the adatom lattice. Our results highlight the potential of Shiba lattices as a platform to design the topology and sample geometry of 2D superconductors.

description: Chiefly authority has been exercised in Western Polynesia for at least 2,000 years. This thesis examines the transformation of chiefly power from its origin to the present-day function it exercises as a constituent element of the political and legal framework of the state. Western Samoa and Tonga are the focus for this study of the interaction of indigenous and introduced elements of politics and law. The approach is necessarily interdisciplinary , and the study commences with a reconstruction of the Samoan and Tongan societies prior to Western contact . Primary and secondary historical sources are then drawn on to recount the processes of the impact of Western ideas and the response of the chiefly systems. Much of the interest centres around the manner in which chiefly power has been recognised in constitutional and statutory provisions over the past 140 years , and the significance of its recognition. Western Samoa and Tonga are treated separately, and the consequences of early differences in political organisation become apparent within the broadly comparative framework. With the persistence of chiefly power as its theme, the study proceeds to examine the nature and role of that power in the political and constitutional settings of the independent states. Challenges to power, such as those posed by Western forms of government and administration, and by institutions for the maintenance of order , the settlement of disputes and the regulation of landholding, are considered in relation to the Western Samoan matai system and the Tongan monarchy and nobility . In response, Western models have been adapted to accommodate some of the realities of chiefly authority , with the culmination, in each state , of a political order in which such authority is entrenched in different ways. The study concludes with a review of the historical processes and a comparison of chiefship in the two societies, and with a discussion of implications for their future political organisation.

description: The Falicov-Kimball model is a simple quantum lattice model that describes light and heavy electrons interacting with an on-site repulsion; alternatively, it is a model of itinerant electrons and fixed nuclei. It can be seen as a simplification of the Hubbard model; by neglecting the kinetic (hopping) energy of the spin up particles, one gets the Falicov-Kimball model. We show that away from half-filling, i.e. if the sum of the densities of both kinds of particles differs from 1, the particles segregate at zero temperature and for large enough repulsion. In the language of the Hubbard model, this means creating two regions with a positive and a negative magnetization. Our key mathematical results are lower and upper bounds for the sum of the lowest eigenvalues of the discrete Laplace operator in an arbitrary domain, with Dirichlet boundary conditions. The lower bound consists of a bulk term, independent of the shape of the domain, and of a term proportional to the boundary. Therefore, one lowers the kinetic energy of the itinerant particles by choosing a domain with a small boundary. For the Falicov-Kimball model, this corresponds to having a single `compact' domain that has no heavy particles.

description: In this paper, a novel architecture of Recurrent Neural Network (RNN) is designed and experimented. The proposed RNN adopts a computational memory based on the concept of stigmergy. The basic principle of a Stigmergic Memory (SM) is that the activity of deposit/removal of a quantity in the SM stimulates the next activities of deposit/removal. Accordingly, subsequent SM activities tend to reinforce/weaken each other, generating a coherent coordination between the SM activities and the input temporal stimulus. We show that, in a problem of supervised classification, the SM encodes the temporal input in an emergent representational model, by coordinating the deposit, removal and classification activities. This study lays down a basic framework for the derivation of a SM-RNN. A formal ontology of SM is discussed, and the SM-RNN architecture is detailed. To appreciate the computational power of an SM-RNN, comparative NNs have been selected and trained to solve the MNIST handwritten digits recognition benchmark in its two variants: spatial (sequences of bitmap rows) and temporal (sequences of pen strokes).

description: Let n >= 1 and let p be a prime. Let t = 1 - zeta_{p^n}. Expand an integer j in [0,p^n-1], coprime to p, p-adically as j = sum_{s >= 0} a_s p^s. Denote the tensor product over Z_(p) by o . Then the #([0,j] - (p))th Z_(p)[t]-linear elementary divisor of the cyclotomic Dedekind embedding Z_(p)[t] o Z_(p)[t] --> prod_{i in (Z/p^n)^*} Z_(p)[t] has valuation -1 + sum_{s >= 0} (a_s (s+1) - a_{s+1} (s+2)) p^s at t. There is a similar result for the related cyclic Wedderburn embedding.

description: The algebraic approach to black hole quantization requires the horizon area eigenvalues to be equally spaced. As shown previously, for a neutral non-rotating black hole, such eigenvalues must be $2^{n}$-fold degenerate if one constructs the black hole stationary states by means of a pair of creation operators subject to a specific algebra. We show that the algebra of these two building blocks exhibits $U(2)\equiv U(1)\times SU(2)$ symmetry, where the area operator generates the U(1) symmetry. The three generators of the SU(2) symmetry represent a {\it global} quantum number (hyperspin) of the black hole, and we show that this hyperspin must be zero. As a result, the degeneracy of the $n$-th area eigenvalue is reduced to $2^{n}/n^{3/2}$ for large $n$, and therefore, the logarithmic correction term $-3/2\log A$ should be added to the Bekenstein-Hawking entropy. We also provide a heuristic approach explaining this result, and an evidence for the existence of {\it two} building blocks.

Non-perturbative SQED beta function using functional renormalization group approach and the NSVZ exact beta function

description: The renormalization group equations of massive $\mathcal{N}=1$ supersymmetric quantum electrodynamics (SQED) are studied using the functional renormalization group approach. A non-perturbative form of the beta function has been computed via a derivative expansion of the effective action. In the local potential approximation, the functional form of the non-perturbative beta function is closely related to the form of the NSVZ exact beta function; this relationship is exact if an effective fine-structure constant is defined. The non-massive limit of the same is also analyzed. Furthermore, the calculation of the beta function has been improved by incorporating the influence of momentum modes on the propagation of the superfields in the non-perturbative running of the electric charge, applying a second-order truncation for the derivative expansion, which we use to find the momentum contributions to the $β$ function. Again, we find the NSVZ relation for an effective fine-structure constant.

 Etymology. The specific name is a patronym given in honor of my friend, Evgeniy Yu. Kulikov (Rubtsovsk, Russia), who helped in the organization of the field trip to Ivanovskyi Mt. Range, where the types of the new species were collected.
 Diagnosis. The new species is similar to the widespread A. lignaria in having triangular epigynal fovea (Fo) and quadrangular septal base (Sb), but differs from this species by the apical pocket (Ap) with one hood (vs. apical pocket with two hoods) and by distinct apical lips of the epigyne (Al) (vs. indistinguishable, cf. Fig. 63 and fig. 120 in Marusik et al. 2004).
 Description. Female (holotype). Total length 8.3. Carapace: 4.2 long, 3.5 wide. General appearance as in Fig. 3. Coloration. Carapace and chelicerae dark brown. Eye field black. Sternum and labium brown. Endites, coxae and palps yellow-brown. Legs yellow-brown with yellow stripes. Femora III–IV with indistinct gray annulation. Abdomen dark gray dorsally, with dark brown cardiac mark. Venter of abdomen yellow-gray. Spinnerets dark gray. Spination of leg I: Fe d1-1-1 p0-0-2 r1-0-1; Pa r1; Ti p1-0-0 r1-0-0 v2-2-2-2-2-2; Mt p0-1-0 r0-1-0 v2-2-0. Leg measurements: I 4.1, 1.8, 3.9, 3.7, 1.65 (15.15); II 4.05, 1.8, 3.7, 3.85, 1.6 (15.0); III 4.0, 1.65, 3.5, 4.8, 1.8 (15.75); IV 4.95, 1.85, 4.5, 6.9, 2.45 (20.65).
 Epigyne and internal genitalia as in Figs 63–65. Fovea is very narrow. Septal base bulging fills almost the entire fovea. Septal stem undeveloped. Lips of the epigyne (Li) separated by twice their width. Apical pocket as wide as septal base. Receptacles (Re) clavate, clearly delineated from copulatory ducts (Cd). Copulatory ducts 2 times shorter than receptacles.
Male unknown.
 Distribution. Known from two closely spaced localities in the Ivanovskyi Mt. Range of the Altai Mountains (Figs 75–76).
 Comments. Members of Acantholycosa lignaria -group can be confidently recognized by males only. Despite this, A. kulikovi sp. n. is herein placed in this group based on strong similarity between its epigyne and those of A. lignaria.

description: This paper addresses the important problem of reconstructing a signal from multiple multirate observations. The observations are modeled as the output of an analysis bank, and time-domain analysis is carried out to design an optimal FIR synthesis bank. We pose this as a minimizing the mean-square problem and prove that at least one optimal solution is always possible. A parametric form for all optimal solutions is obtained for a non-maximally decimated filter bank. The necessary and sufficient conditions for an optimal solution, that results in perfect reconstruction (PR), are derived as time-domain pseudocirculant conditions. This represents a novel theoretical contribution in multirate filter bank theory. We explore PR in a more general setting. This results in the ability to design a synthesis bank with a particular delay in the reconstruction. Using this delay, one can achieve PR in cases where it might not have been possible otherwise. Further, we extend the design and analysis to non-uniform filter banks and carry out simulations to verify the derived results.

description: Large Language Models (LLMs) have revolutionized Artificial Intelligence (AI) services due to their exceptional proficiency in understanding and generating human-like text. LLM chatbots, in particular, have seen widespread adoption, transforming human-machine interactions. However, these LLM chatbots are susceptible to "jailbreak" attacks, where malicious users manipulate prompts to elicit inappropriate or sensitive responses, contravening service policies. Despite existing attempts to mitigate such threats, our research reveals a substantial gap in our understanding of these vulnerabilities, largely due to the undisclosed defensive measures implemented by LLM service providers.
 In this paper, we present Jailbreaker, a comprehensive framework that offers an in-depth understanding of jailbreak attacks and countermeasures. Our work makes a dual contribution. First, we propose an innovative methodology inspired by time-based SQL injection techniques to reverse-engineer the defensive strategies of prominent LLM chatbots, such as ChatGPT, Bard, and Bing Chat. This time-sensitive approach uncovers intricate details about these services' defenses, facilitating a proof-of-concept attack that successfully bypasses their mechanisms. Second, we introduce an automatic generation method for jailbreak prompts. Leveraging a fine-tuned LLM, we validate the potential of automated jailbreak generation across various commercial LLM chatbots. Our method achieves a promising average success rate of 21.58%, significantly outperforming the effectiveness of existing techniques. We have responsibly disclosed our findings to the concerned service providers, underscoring the urgent need for more robust defenses. Jailbreaker thus marks a significant step towards understanding and mitigating jailbreak threats in the realm of LLM chatbots.

description: Acantholycosa baltoroi group
 Acantholycosa baltoroi group — Marusik et al. 2004: 112.
 Diagnosis. Members of this group can be easily distinguished based on the following features: palea with a prominent extension in the terminal part and a triangle-shaped projection on the posterior edge, robust terminal apophysis with bifurcate or truncate tip, and anchor-shaped septum (Marusik et al. 2004).
 Composition. This species group includes six species: A. baltoroi (Caporiacco, 1935) (Himalaya, Tibet and Central, Northern and Northeastern China), A. levinae Marusik, Azarkina & Koponen, 2004 (Altai Mountains), A. sergeevi sp. n. (Western Sayan Mountains), A. solituda (Levi & Levi, 1951) (Rocky Mountains, USA), A. sterneri (Marusik, 1993) (Southern Siberia and Mongolia) and A. zonsteini Marusik & Omelko, 2017 (Sikhote-Alin Mountains).
 Comments. It should be noted that the baltoroi -group might represent a separate genus due to the unique cutlike palea with a relatively small, triangle-shaped projection, instead of well-developed paleal apophysis (Marusik et al. 2004).

Mixing Sinc kernels to improve interpolations in smoothed particle hydrodynamics without pairing instability

description: The smoothed particle hydrodynamic technique is strongly based on the proper choice of interpolation functions. This statement is particularly relevant for the study of subsonic fluxes and turbulence, where inherent small errors in the averaging procedures introduce excessive damping on the smallest scales. To mitigate these errors we can increase both the number of interpolating points and the order of the interpolating kernel function. However, this approach leads to a higher computational burden across all fluid regions. Ideally, the development of a single kernel function capable of effectively accommodating varying numbers of interpolating points in different fluid regions, providing good resolution and minimal errors would be highly desirable. In this work, we revisit and extend the main properties of a family of interpolators called $Sinc~kernels$ and compare them with the widely used family of Wendland kernels. We show that a linear combination of low- and high-order Sinc kernels generates good-quality interpolators, which are resistant to pairing instability while maintaining good sampling properties in a wide range of neighbor interpolating points, $60\le n_b\le 400$. We show that a particular case of this linear mix of Sincs produces a well-balanced and robust kernel that improves previous results in the Gresho-Chan vortex experiment even when the number of neighbors is not large, while yielding a good convergence rate. Although such a mixing technique is ideally suited for Sinc kernels owing to their excellent flexibility, it can be easily applied to other interpolating families such as the B-splines and Wendland kernels.
