X-ray spectral studies of TeV gamma-ray emitting blazars
Creators: name: Wierzcholska, Alicja

description: This work is a summary of the X-ray spectral studies of 29 TeV $γ$-ray emitting blazars observed with Swift/XRT, especially focusing on sources for which X-ray regime allows to study the low and the high energy ends of the particle distributions function. Variability studies require simultaneous coverage, ideally sampling different flux states of each source. This is achieved using X-ray observations by disentangling the high-energy end of the synchrotron emission and the low-energy end of the Compton emission, which are produced by the same electron population. We focused on a sample of 29 TeV gamma-ray emitting blazars with the best signal-to-noise X-ray observations collected with Swift/XRT in the energy range of 0.3-10 keV during 10 years of Swift/XRT operations. We investigate the X-ray spectral shapes and the effects of different corrections for neutral hydrogen absorption and decompose the synchrotron and inverse Compton components. In the case of 5 sources (3C 66A, S5 0716+714, W Comae, 4C +21.35 and BL Lacertae) a superposition of both components is observed in the X-ray band, permitting simultaneous, time resolved studies of both ends of the electron distribution. The analysis of multi-epoch observations revealed that the break energy of X-ray spectrum varies only by a small factor with flux changes. Flux variability is more pronounced in the synchrotron domain (high-energy end of the electron distribution) than in the Compton domain (low energy end of the electron distribution). The spectral shape of the Compton domain is stable, while the flux of the synchrotron domain is variable. These changes cannot be described by simple variations of the cut-off energy, suggesting that the high-energy end of the electron distribution is not generally well-described by cooling only.

description: Gold atomic point contacts are prototype systems to evidence ballistic electron transport. The typical dimension of the nanojunction being smaller than the electron-phonon interaction length, even at room temperature, electrons transfer their excess energy to the lattice only far from the contact. At the contact however, favored by huge current densities, electron-electron interactions result in a nano hot electron gas acting as a source of photons. Using a home built Mechanically Controlled Break Junction, it is reported here, for the first time, that this hot electron gas also radiates in the infrared range (0.2eV to 1.2eV). Moreover, in agreement with the pioneering work of Tomchuk, we show that this radiation is compatible with a blackbody like spectrum emitted from an electron gas at temperatures of several thousands of Kelvin given by $(kB.Te)^2 = α. I.V$ where $α$, $I$ and $V$ are respectively a fitting parameter, the current flowing and the applied bias.

description: We propose NEDS-SLAM, a dense semantic SLAM system based on 3D Gaussian representation, that enables robust 3D semantic mapping, accurate camera tracking, and high-quality rendering in real-time. In the system, we propose a Spatially Consistent Feature Fusion model to reduce the effect of erroneous estimates from pre-trained segmentation head on semantic reconstruction, achieving robust 3D semantic Gaussian mapping. Additionally, we employ a lightweight encoder-decoder to compress the high-dimensional semantic features into a compact 3D Gaussian representation, mitigating the burden of excessive memory consumption. Furthermore, we leverage the advantage of 3D Gaussian splatting, which enables efficient and differentiable novel view rendering, and propose a Virtual Camera View Pruning method to eliminate outlier gaussians, thereby effectively enhancing the quality of scene representations. Our NEDS-SLAM method demonstrates competitive performance over existing dense semantic SLAM methods in terms of mapping and tracking accuracy on Replica and ScanNet datasets, while also showing excellent capabilities in 3D dense semantic mapping.

description: Phase transitions are investigated in the Bose-Fermi-Hubbard model in the mean field and hard-core boson approximations for the case of infinitely small fermion transfer and repulsive on-site boson-fermion interaction. The behavior of the Bose-Einstein condensate order parameter and grand canonical potential is analyzed as functions of the chemical potential of bosons at zero temperature. The possibility of change of order of the phase transition to the superfluid phase in the regime of fixed values of the chemical potentials of Bose- and Fermi-particles is established. The relevant phase diagrams are built.

description: High-entropy alloys (HEAs) are attracting attention due to their exceptional properties, such as enhanced mechanical toughness, superconducting robustness, and thermoelectric performance. Numerous HEAs have been developed for diverse applications, ranging from self-healing in fusion reactors to addressing environmental concerns with thermoelectric materials. Understanding atomic diffusion within HEA crystals is crucial for these applications. Here, this study investigates diffusion mechanisms in PbTe-based HEAs, focusing on the role of indium (In). Molecular dynamics simulations reveal that In inclusion prompts spontaneous Frenkel defect formation, notably enhancing diffusion not only of In$^+$ but also other cations. Frenkel defect formation, closely linked to alloy properties, is predominantly influenced by charge rather than cation size. This insight not only enhances comprehension of HEA diffusion mechanisms but also develops HEAs with properties such as self-healing from damage and high ion permeability, advancing the field of material science.

description: Super-resolution fluorescence microscopy is of great interest in life science studies for visualizing subcellular structures at the nanometer scale. Among various kinds of super-resolution approaches, image scanning microscopy (ISM) offers a doubled resolution enhancement in a simple and straightforward manner, based on the commonly used confocal microscopes. ISM is also suitable to be integrated with multi-photon microscopy techniques, such as two-photon excitation and second-harmonic generation imaging, for deep tissue imaging, but it remains the twofold limited resolution enhancement and requires expensive femtosecond lasers. Here, we present and experimentally demonstrate the super-linear ISM (SL-ISM) to push the resolution enhancement beyond the factor of two, with a single low-power, continuous-wave, and near-infrared laser, by harnessing the emission nonlinearity within the multiphoton excitation process of lanthanide-doped upconversion nanoparticles (UCNPs). Based on a modified confocal microscope, we achieve a resolution of about 120 nm, 1/8th of the excitation wavelength. Furthermore, we demonstrate a parallel detection strategy of SL-ISM with the multifocal structured excitation pattern, to speed up the acquisition frame rate. This method suggests a new perspective for super-resolution imaging or sensing, multi-photon imaging, and deep-tissue imaging with simple, low-cost, and straightforward implementations.

Retrieval of canopy chlorophyll content from hyperspectral sensing for bark beetle detection
Creators: name: Höppner, Johanne Malin
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: The European spruce bark beetle (Ips typographus) is an essential component of spruce ecosystems. Yet, for the forest industry, infestation may present serious economic loss. Early detection of bark beetles (green attack detection) is difficult due to infested trees not showing visual symptoms and biochemical changes being subtle. Chlorophyll is the primary pigment driving photosynthesis, and chlorophyll content is known to decrease responding to stress, including insect infestation. This study aimed at investigating the potential of airborne hyperspectral sensing to detect bark beetle green attack. It compared different models (narrowband VIs, PLSR and RF) in their accuracy to predict canopy chlorophyll content (CCC) by relating hyperspectral data with quantitative field measurements. Subsequently, it determined whether predicted CCC may be used to discriminate between healthy and green attacked areas. The study yielded the highest retrieval accuracies with PLSR (RMSE=0.25g/m2, R2=0.66). It indicated specific regions within the visible, red edge, NIR and SWIR regions that were important for CCC retrieval. The difference in CCC between green attacked and healthy areas was not significant. However, the constraints of the employed research design were identified, and changes for future research suggested to ascertain whether green attack detection using remote sensing technology is possible.

description: Quantum steering is a relatively simple test for quantumness of correlations, proving that the values of quantum-mechanical measurement outcomes come into being only in the act of measurement. By exploiting quantum correlations Alice can influence -- steer -- Bob's physical system in a way inaccessible in classical world, leading to violation of some inequalities. Demonstrating this and similar quantum effects for systems of increasing size, approaching even the classical limit, is a long-standing challenging problem. Here we provide experimentally feasible signature of unbounded violation of a steering inequality. We derive its universal form where tolerance for measurement-setting-errors is explicitly build-in by means of the Deutsch-Maassen-Uffink uncertainty relation. Then, generalizing the mutual unbiasedness, we apply the inequality to the multi-singlet and multi-particle bipartite Bell-state. However, the method is general and opens the possibility of employing multi-particle bipartite steering for randomness certification and development of quantum technologies, e.g.\ random access codes.

description: We show that electric fields in compactified spaces may produce Kaluza-Klein (KK) particles even when the energy of electric fields is smaller than KK scale. As an illustrating example, we consider a charged massless complex scalar coupled to U(1) gauge theory in $\mathbb{R}^{1,3}\times {\mathbb S}^1$ and discuss the effect of background gauge potential along a compact direction. The electric field produces the charged Kaluza-Klein particle non-perturbatively, which we call KK Schwinger effect. We quantitatively show that KK modes can be produced even when the electric field energy is much below the KK scale. The mechanism is rather general and similar phenomena would occur in any compactification models when a gauge potential along compact direction evolves in time and experiences large enough field excursion. We also discuss the subtlety of four dimensional effective theory truncated by KK modes at an initial time, when the electric field is turned on.

description: This paper studies the storage-latency tradeoff in the $3\times3$ wireless interference network with caches equipped at all transmitters and receivers. The tradeoff is characterized by the so-called fractional delivery time (FDT) at given normalized transmitter and receiver cache sizes. We first propose a generic cooperative transmitter/receiver caching strategy with adjustable file splitting ratios. Based on this caching strategy, we then design the delivery phase carefully to turn the considered interference channel opportunistically into broadcast channel, multicast channel, X channel, or a hybrid form of these channels. After that, we obtain an achievable upper bound of the minimum FDT by solving a linear programming problem of the file splitting ratios. The achievable FDT is a convex and piece-wise linear decreasing function of the cache sizes. Receiver local caching gain, coded multicasting gain, and transmitter cooperation gain (interference alignment and interference neutralization) are leveraged in different cache size regions.

description: This article presents the findings of a survey conducted in Turkey to evaluate the competencies and training experiences of radiology residents and specialists in obstetric ultrasound. The study highlights deficiencies in postgraduate training, including a low number of patients cared for, insufficient rotation time, and a lack of theoretical courses. Specialists considered themselves more competent compared to residents. Continuous medical training was identified as an important factor for acquiring competencies. The study emphasizes the need for improved obstetric ultrasound training in radiology residency programs and ongoing education for specialists. Understanding and teaching professionalism in medicine is crucial for medical schools and healthcare systems. Professionalism encompasses ethical behavior, communication skills, and commitment to patient care. It ensures trust, integrity, and accountability in healthcare. By integrating professionalism into the medical curriculum, medical students can develop the necessary skills and values to become competent and compassionate healthcare professionals, ultimately improving patient outcomes and the overall quality of healthcare delivery.

description: Let $F$ be a compact set of a Banach space $\mathcal{X}$. This paper analyses the "Generalized Empirical Interpolation Method" (GEIM) which, given a function $f\in F$, builds an interpolant $\mathcal{J}_n[f]$ in an $n$-dimensional subspace $X_n \subset \mathcal{X}$ with the knowledge of $n$ outputs $(σ_i(f))_{i=1}^n$, where $σ_i\in \mathcal{X}'$ and $\mathcal{X}'$ is the dual space of $\mathcal{X}$. The space $X_n$ is built with a greedy algorithm that is adapted to $F$ in the sense that it is generated by elements of $F$ itself. The algorithm also selects the linear functionals $(σ_i)_{i=1}^n$ from a dictionary $Σ\subset \mathcal{X}'$. In this paper, we study the interpolation error $\max_{f\in F} \Vert f-\mathcal{J}_n[f]\Vert_{\mathcal{X}}$ by comparing it with the best possible performance on an $n$-dimensional space, i.e., the Kolmogorov $n$-width of $F$ in $\mathcal{X}$, $d_n(F,\mathcal{X})$. For polynomial or exponential decay rates of $d_n(F,\mathcal{X})$, we prove that the interpolation error has the same behavior modulo the norm of the interpolation operator. Sharper results are obtained in the case where $\mathcal X$ is a Hilbert space.

Fast and compact self-stabilizing verification, computation, and fault detection of an MST

description: This paper demonstrates the usefulness of distributed local verification of proofs, as a tool for the design of self-stabilizing algorithms.In particular, it introduces a somewhat generalized notion of distributed local proofs, and utilizes it for improving the time complexity significantly, while maintaining space optimality. As a result, we show that optimizing the memory size carries at most a small cost in terms of time, in the context of Minimum Spanning Tree (MST). That is, we present algorithms that are both time and space efficient for both constructing an MST and for verifying it.This involves several parts that may be considered contributions in themselves.First, we generalize the notion of local proofs, trading off the time complexity for memory efficiency. This adds a dimension to the study of distributed local proofs, which has been gaining attention recently. Specifically, we design a (self-stabilizing) proof labeling scheme which is memory optimal (i.e., $O(\log n)$ bits per node), and whose time complexity is $O(\log ^2 n)$ in synchronous networks, or $O(Δ\log ^3 n)$ time in asynchronous ones, where $Δ$ is the maximum degree of nodes. This answers an open problem posed by Awerbuch and Varghese (FOCS 1991). We also show that $Ω(\log n)$ time is necessary, even in synchronous networks. Another property is that if $f$ faults occurred, then, within the requireddetection time above, they are detected by some node in the $O(f\log n)$ locality of each of the faults.Second, we show how to enhance a known transformer that makes input/output algorithms self-stabilizing. It now takes as input an efficient construction algorithm and an efficient self-stabilizing proof labeling scheme, and produces an efficient self-stabilizing algorithm. When used for MST, the transformer produces a memory optimal self-stabilizing algorithm, whose time complexity, namely, $O(n)$, is significantly better even than that of previous algorithms. (The time complexity of previous MST algorithms that used $Ω(\log^2 n)$ memory bits per node was $O(n^2)$, and the time for optimal space algorithms was $O(n|E|)$.) Inherited from our proof labelling scheme, our self-stabilising MST construction algorithm also has the following two properties: (1) if faults occur after the construction ended, then they are detected by some nodes within $O(\log ^2 n)$ time in synchronous networks, or within $O(Δ\log ^3 n)$ time in asynchronous ones, and (2) if $f$ faults occurred, then, within the required detection time above, they are detected within the $O(f\log n)$ locality of each of the faults. We also show how to improve the above two properties, at the expense of some increase in the memory.

These switchings between low-amplitude oscillations, nonlinear waves, and extreme events strongly resemble a random process, although the system is deterministic. We show that a chaotic saddle -- which contains all the patterns as well as channel-like structures that mediate the transitions between them -- is the backbone of such a pattern switching dynamics. Our analyses indicate that essential ingredients for the observed phenomena are that the system behaves like an inhomogeneous oscillatory medium that is capable of self-generating spatially localized excitations and that is dominated by short-range connections but also features long-range connections. With our findings, we present an alternative to the well-known ways to obtain self-induced pattern switching, namely noise-induced attractor hopping, heteroclinic orbits, and adaptation to an external signal. This alternative way can be expected to improve our understanding of pattern switchings in spatially extended natural dynamical systems like the brain and the heart.

description: The magnetic structure of the spin-chain antiferromagnet SrCo2V2O8 is determined by single-crystal neutron diffraction experiment. The system undergoes magnetic long range order below T_N = 4.96 K. The moment of 2.16μ_B per Co at 1.6 K in the screw chain running along the c axis alternates in the c-axis. The moments of neighboring screw chains are arranged antiferromagnetically along one in-plane axis and ferromagnetically along the other in-plane axis. This magnetic configuration breaks the 4-fold symmetry of the tetragonal crystal structure and leads to two equally populated magnetic twins with antiferromagnetic vector in the a or b axis. The very similar magnetic state to the isostructural BaCo2V2O8 warrants SrCo2V2O8 another interesting half-integer spin-chain antiferromagnet for investigation on quantum antiferromagnetism.

description: We extend to the Toda lattice hierarchy the approach of [3, 4] to computation of logarithmic derivatives of tau-functions in terms of the so-called matrix resolvents of the corresponding differ- ence Lax operator. As a particular application we obtain explicit generating series for connected GUE correlators. On this basis an efficient recursive procedure for computing the correlators in full genera is developed.

description: Artificial quantum systems have emerged as indispensable platforms to realize exotic topological matter in a well-controlled manner. Here, we demonstrate topological quantum Heisenberg spin lattices, engineered with spin chains and two-dimensional spin arrays using spin 1/2 atoms on insulating films in a scanning tunnelling microscope (STM). We engineered with atomic precision both topological and trivial phases of the quantum spin model, realizing first- and second-order topological quantum magnets. Their many-body excitations were probed by single-atom electron spin resonance with ultrahigh energy resolution. The atomically-localized magnetic field of the STM tip allows us to directly visualize various topological bound modes including topological edge states, topological defects, and higher-order corner modes. Our results provide an important bottom-up approach to simulating exotic quantum many-body phases of interacting spins.

description: The theory of nucleation of nanoscale structures of the adsorbed atoms (adatoms), which occurs as a result of the self-consistent interaction of adatoms with the surface acoustic wave and electronic subsystem is developed. Temperature regimes of formation of nanoclusters on ${n}$-GaAs surface under the action of laser irradiation are investigated. The offered model permits to choose optimal technological parameters (temperature, doping degree, intensity of laser irradiation) for the formation of the surface periodic defect-deformation structures under the action of laser irradiation.

Under the Magnifying Glass: Kazuo Ishiguro's When We Were Orphans
Creators: name: Calinescu, Amalia
Publisher: name: figshare
Year: 2023
Subjects: classificationCode: 470504
subject: British and Irish literature

description: The study proposes a theoretical analysis of Kazuo Ishiguro’s fifth novel from an interdisciplinary-holistic perspective on the nostalgic nature of the narrative. Firstly, some of the author's interviews are brought to the fore, in which he openly discusses the influences of the English detective novels from the 1920s and 1930s. The emotional logic behind Christopher Banks’ exaggerated professionalism and failed metacognition is then explained through the Dunning-Kruger effect. In the second part, the study deals extensively with the parentless theme, bringing forth other examples of orphan children, such as those in the Broadway musical Annie. Eric Berne’s life scenario is used to explain the nostalgic nature of the novel, which leads to a reinterpretation of the temporal subordinate in the title. In all three cases of orphanhood in the novel, the characters’ life scenarios are rewritten. Through conscious effort, Christopher, Jennifer and Sarah decide to break away from their past and appreciate their present. The moment they see the harshness of the world around them as an inherent part of their development and growth, they embrace their orphanhood, just as all children should do while stepping out of the protective bubble their parents have built around them.

description: This report presents a general model of the architecture of information systems for the speech recognition of children. It presents a model of the speech data stream and how it works. The result of these studies and presented veins architectural model shows that research needs to be focused on acoustic-phonetic modeling in order to improve the quality of children's speech recognition and the sustainability of the systems to noise and changes in transmission environment. Another important aspect is the development of more accurate algorithms for modeling of spontaneous child speech.

description: We study polynomial identities of finite dimensional simple color Lie superalgebras over an algebraically closed field of characteristic zero graded by the product of two cyclic groups of order $2$. We prove that the codimensions of identities grow exponentially and the rate of exponent equals the dimension of the algebra. A similar result is also obtained for graded identities and graded codimensions.

Remarks
This species was described from six females, of which two syntypes were found. The specimen numbered 9.713 is mounted on a card and is missing part of the right fore leg; the other is mounted on a card point and is missing the tip of the right hind leg. Both belong to Trichopria. In his treatment of this species Ashmead used the specific name grenadensis in the key (p. 809) and angulifera heading the description (p. 810 line 44 - species number 3) as is evident from the correspondence between the characters used in the key and the description, hence P. angulifera Ashmead, 1896: 810 line 44 and P. grenadensis are multiple original spellings. Ashmead (1900) is the first reviser under Art. 24.2.4, and he chose P. grenadensis as the correct original spelling. P. angulifera Ashmead, 1896: 810 line 44 is thus an incorrect original spelling, has no separate availability and cannot enter into homonymy with P. angulifera Ashmead, 1896: 810 lines 12, 29 (species number 2) q. v. above.

description: This study examined gender-related differences in measurements of the medial malleolus groove (MMG) and tendons passing through it. A total of 103 patients were included, and various measurements were taken. Findings revealed statistically significant differences between genders in MMG depth, width, and length, as well as in the width and thickness of the posterior tibial tendon (PTT) and flexor digitorum longus tendon (FDLT). The study suggests that these measurements can be used for gender differentiation and may have implications in forensic identification and surgical procedures. Additionally, the presence of asymptomatic cases without a detectable MMG highlights the need to consider other pathologies in addition to MMG depth. This study is important as it contributes to the understanding of gender-related differences in the measurements of the medial malleolus groove (MMG) and associated tendons. By identifying statistically significant differences between genders, such as MMG depth, width, and length, as well as the dimensions of the posterior tibial tendon (PTT) and flexor digitorum longus tendon (FDLT), it enhances our knowledge of anatomical variations between males and females in this region. This information can have practical implications in various fields. For forensic identification, these measurements can aid in gender differentiation when examining skeletal remains or unidentified individuals. In surgical procedures, particularly those involving the MMG and tendons, these measurements can help determine optimal surgical techniques and implant sizing, leading to improved surgical outcomes. Furthermore, the presence of asymptomatic cases without a visible MMG raises awareness of potential variations and other underlying pathologies in the region. Overall, this study provides valuable insights into the anatomical differences in the MMG and tendons between genders, enhancing our understanding and potentially influencing various medical disciplines.

description: We theoretically investigate the tunneling transport in a repulsively interacting ultracold Bose-Fermi mixture. A two-terminal model is applied to such a mixture and the supersymmetric-like tunneling current through the junction can be induced by the bias of fermion chemical potential between two reservoirs. The Goldstino, which is the Nambu-Goldstone fermionic mode associated with the spontaneous sypersymmetry breaking and appears as a gapped mode in the presence of the explicit supersymmetry breaking in existing Bose-Fermi mixtures, is found to contribute to the tunneling transport as a supercharge exchanging process. Our study provides a potential way to detect the Goldstino transport in cold atom experiments.
