description: We report the discovery of a pulsar with period P = 136 ms and dispersion measure 308 cm-3 pc in a deep observation of the supernova remnant (SNR) G54.1+0.3 with the Arecibo radio telescope. Timing measurements of the new pulsar, J1930+1852, reveal a characteristic age of P/2 = 2900 yr and a spin-down luminosity of = 1.2 × 1037 ergs s-1. We have subsequently searched archival ASCA X-ray data of this SNR and detect pulsations with a consistent period. These findings ensure that PSR J1930+1852 is the pulsar that powers the "Crab-like" SNR G54.1+0.3. Together with existing Chandra observations of the SNR, we derive an X-ray pulsed fraction (2-10 keV) of 27%. We also find that the cooling efficiency of the pulsar wind nebula (PWN) is intermediate between those of the Vela and Crab PWNe: LX(2-10 keV) ~ 0.002. PSR J1930+1852 is a very weak radio source, with a period-averaged flux density at 1180 MHz of 60 μJy. For a distance of 5 kpc, its luminosity, ~1 mJy kpc2, is among the lowest for known young pulsars.

description: Infineon has identified a need for engineers, account managers, and customers to rapidly obtain product information. This problem is traditionally addressed with retrieval-augmented generation (RAG) chatbots, but in this study, I evaluated the use of the newly popularized RAG-Fusion method. RAG-Fusion combines RAG and reciprocal rank fusion (RRF) by generating multiple queries, reranking them with reciprocal scores and fusing the documents and scores. Through manually evaluating answers on accuracy, relevance, and comprehensiveness, I found that RAG-Fusion was able to provide accurate and comprehensive answers due to the generated queries contextualizing the original query from various perspectives. However, some answers strayed off topic when the generated queries' relevance to the original query is insufficient. This research marks significant progress in artificial intelligence (AI) and natural language processing (NLP) applications and demonstrates transformations in a global and multi-industry context.

Re-writing History / Re-constructing Memory: Uses and Re-uses of Archival and Found Footage in Yervant Gianikian and Angela Ricci Lucchi’s Barbaric Land (Pays Barbare, 2013)

description: In the realm of the moving image we can find several examples of a tendency to revisit the past in order to rewrite or reconstruct historical events. Following the ideas of Ariella Azoulay (2019, 2013) about the potential history as a way to imagine other possible histories and the role of the archival materials for the reconstruction of the narratives about the past, this article analyzes the ways in which Yervant Gianikian (1942) and Angela Ricci Lucchi (1942-2018), throughout their works, call into question the hegemonic narratives of history. I will focus in the analysis of their film Barbaric Land (Pays Barbare, France, 2013), in which the directors worked with archival footage from the 1920's and 1930's, related to the Italian colonization of Ethiopia. The text addresses how, by using montage as a theoretical and technological tool, the couple examine critically those documents and narratives to contrast the colonial politics of Mussolini with the shocking reality of the African territory and its inhabitants. Finally, the paper analyzes the manipulation processes of those materials and the ways in which they explore the Fascist ideology that produced the images of the so called “barbaric land” and its “primitive” inhabitants.

description: We propose an improved tensor renormalization group (TRG) algorithm, the bond-weighted TRG (BTRG). In BTRG, we generalize the conventional TRG by introducing bond weights on the edges of the tensor network. We show that BTRG outperforms the conventional TRG and the higher-order tensor renormalization group with the same bond dimension, while its computation time is almost the same as that of TRG. Furthermore, BTRG can have non-trivial fixed-point tensors at an optimal hyperparameter. We demonstrate that the singular value spectrum obtained by BTRG is invariant under the renormalization procedure in the case of the two-dimensional Ising model at the critical point. This property indicates that BTRG performs the tensor contraction with high accuracy while keeping the scale-invariant structure of tensors.

Degenerate Fermions and Wilson Loop in $1+1$ Dimensions

description: We investigate the effect of finite fermion density on symmetry breaking by Wilson loops in $(1+1)$ dimensions. We find the breaking and restoration of symmetry at finite density in the models with $SU(2)$ and $SU(3)$ gauge symmetries, in the presence of the adjoint fermions. The transition can occur at a finite density of fermions, regardless of the periodic or antiperiodic boundary condition of the fermion field; this is in contrast to the finite-temperature ease examined by Ho and Hosotani (Nucl. Phys. B345 (1990) 445) where the boundary condition of fractional twist is essential to the occurrence of the phase transition.

The Relation of Gender and Perception of Others for Support Erosion

Subjects: subject: 170199 Psychology not elsewhere classified
subject: FOS: Psychology

description: Previous research on social support and depressive symptoms has found a relation between decreases in social support and increases in depressive symptoms. However, it is not clear whether support leads to decreases in depressive symptoms (support alleviation) or depressive symptoms leads to a decrease in support provision (support erosion). The current study explored this causal relation by having pairs of same‐sex friends complete measures of support requests, receipt, provision, and other support variables within that friendship three times over a six‐week period. We also explored whether the relation depended on gender, possible mechanisms behind the relation, and conducted exploratory analysis on relationship quality. Results showed no evidence for support alleviation but evidence for support erosion occurring for females. Provider burden limitedly explains this finding. Overall relationship quality does not seem to be influenced by depression. Future research should address communal strength in conjunction with the depressive symptom and social support relation.

description: In this article, we ponder how exile impacts the act of filming and its results in amateur filmmaking. I do so by studying the family films made by Herbert Duschenes, a German, partly Jewish architect and art history lecturer who moved to Brazil in 1940. I specifically analyze a sequence of the short film Ronny – 1949-1950 (1950), part of his earlier work focusing on the family he started in São Paulo. Thus, I address the sensitive relationship between the native household help that appears on camera and their European employer behind it, by bringing to light the interaction between the African-Brazilian nannies and the family they assist, and the blurry boundaries regarding the place these servants occupy not only in the home and society, but in the frame.

Since the prediction of a flare by RATAN-600, the source has been monitored from Jan 27 (UT) with these radio telescopes. At the eighteenth day after the quench of the activity, successive flares exceeding 1 Jy were observed successfully. The time scale of the variability in the active phase is presumably shorter in higher frequency bands. We also present the result of a follow-up VLBI observation at 8.4 GHz with the Japanese VLBI Network (JVN) 2.6 days after the first rise. The VLBI image exhibits a single core with a size of <8 mas (80 AU). The observed image was almost stable, although the core showed rapid variation in flux density. No jet structure was seen at a sensitivity of $T_b = 7.5\times 10^5$ K.

The Processing and Structure of Kanji and their Implications for Kanji Acquisition: a Theoretical Approach to Kanji Literacy
Creators: name: Hermalin, Noah

Year: 2015
Subjects: subject: Philosophy
subject: FOS: Philosophy, ethics and religion

description: The following paper approaches the topic of learning Japanese logographic characters, known as kanji, from the perspectives of both linguistic processing and second language acquisition. Three existing methods of kanji learning are analyzed in relation to four proposed key criteria of kanji literacy, and research on kanji structure and processing are synthesized to achieve a stronger understanding of the relationships between kanji, the Japanese language, and literacy. Finally, the information from the first two sections is tied together and a novel method of kanji learning, which is consistent with the results and evidence regarding kanji learning and kanji processing, is proposed.
Archival Re-appropriation and Discontents of Self-cine-identification in Iranian Cinema

Subjects: archival footages; cinematic strategies, re-appropriation, Islamic Republic of Iran; cinematic self-image

description: The indexical interpretation of the archival footages and historical theme of Mohsen Makhmalbaf's Once Upon a Time, Cinema (Iran 1991) has inspired many studies to read the movie as a semi-historical homage to (Iranian) cinema from 1900. However, this article questions the archival footages and cinematic strategies of the movie not as indexes/evidences of/from the past rather as organs of a crisis in remembering and forgetting in relation to the official power and the filmmaker’s career. In order to give a character to this crisis, this paper employs the notion of self-image or self-identification of the artist and the official power through cinema and archival images. This cine-memory crisis is traced in three overlapping forms of the artistic memory, the memory of power (both the post-revolution 1979 and the Qajar in 1900), and the memory of the religion (Islam). This article argues that beyond the represented political motifs and historical indexicality in the movie, the archival footages and history of cinema underline and perpetuate struggles in self-imaging/imagining with the medium of cinema in Iran since 1900. This investigation helps us understand how manipulating archival footages is not an artistic narrative or homage to the past but rather a product of hardships of cinematic re-appropriation or a re-personification of ‘self’ (artistic or institutional) in the present. Furthermore, in a bigger picture, it sheds light on the internal dynamics and paradoxes in Iranian post-revolution movies which are not tangible on the screen.

Maximum principle satisfying CWENO schemes for non-local conservation laws

description: Central WENO schemes are a natural candidate for higher-order schemes for non-local conservation laws, since the underlying reconstructions do not only provide single point values of the solution but a complete (high-order) reconstruction in every time step, which is beneficial to evaluate the integral terms. Recently, in [C. Chalons et al., SIAM J. Sci. Comput., 40(1), A288-A305], Discontinuous Galerkin (DG) schemes and Finite Volume WENO (FV-WENO) schemes have been proposed to obtain high-order approximations for a certain class of non-local conservation laws. In contrast to their schemes, the presented CWENO approach neither requires a very restrictive CFL condition (as the DG methods) nor an additional reconstruction step (as the FV-WENO schemes). Further, by making use of the well-known linear scaling limiter of [X. Zhang and C.-W. Shu, J. Comput. Phys., 229, p. 3091-3120], our CWENO schemes satisfy a maximum principle for suitable non-local conservation laws.

description: Feature extraction with convolutional neural networks (CNNs) is a popular method to represent images for machine learning tasks. These representations seek to capture global image content, and ideally should be independent of geometric transformations. We focus on measuring and visualizing the shift invariance of extracted features from popular off-the-shelf CNN models. We present the results of three experiments comparing representations of millions of images with exhaustively shifted objects, examining both local invariance (within a few pixels) and global invariance (across the image frame). We conclude that features extracted from popular networks are not globally invariant, and that biases and artifacts exist within this variance. Additionally, we determine that anti-aliased models significantly improve local invariance but do not impact global invariance. Finally, we provide a code repository for experiment reproduction, as well as a website to interact with our results at https://jakehlee.github.io/visualize-invariance.

description: We have observed the effect of pseudo magnetic field originating from the polaritonic analog of spin-orbit coupling (TE$-$TM splitting) on a polariton condensate in a ring-shaped microcavity. The effect gives rise to a stable four-leaf pattern around the ring as seen from the linear polarization measurements of the condensate photoluminescence. This pattern is found to originate from the interplay of the cavity potential, energy relaxation, and TE-TM splitting in the ring. Our observations are compared to the dissipative one-dimensional spinor Gross-Pitaevskii equation with the TE-TM splitting energy which shows good qualitative agreement.

Modification of the resistive tearing instability with Joule heating by shear flow

description: We investigate the influence of background shear flow on linear resistive tearing instabilities with Joule heating for two compressible plasma slab configurations: a Harris current sheet and a force-free, shearing magnetic field that varies its direction periodically throughout the slab, possibly resulting in multiple magnetic nullplanes. To do so, we exploit the latest version of the open-source, magnetohydrodynamic spectroscopy tool Legolas. Shear flow is shown to dramatically alter tearing behaviour in the presence of multiple magnetic nullplanes, where the modes become propagating due to the flow. Finally, the tearing growth rate is studied as a function of resistivity, showing where it deviates from analytic scaling laws, as well as the Alfvén speed, the plasma-beta, and the velocity parameters, revealing surprising nuance in whether the velocity acts stabilising or destabilising. We show how both slab setups can produce growth rate regimes which deviate from analytic scaling laws, such that systematic numerical spectroscopic studies are truly necessary, for a complete understanding of linear tearing behaviour in flowing plasmas.

The metric we obtain reproduces to leading order the metric recently found as a direct solution of the Einstein equations in five dimensions. Our results are also in agreement with recent exact results in three dimensions.

Subjects: Dissociative appropriation; hip-hop; articulation; space in cinema

description: Zoya Akhtar’s commercially and critically successful coming-of-age drama Gully Boy (2019), ostensibly traces the history of Mumbai-based rappers Divine and Naezy. It repurposes songs performed by them and other rappers based out of the city, and features a cover version of a music video by Divine and Neazy that borrows from the visual aesthetic of the "original". Gully Boy is imbricated in a dissonant relationship with the dominant ideology and the idea of authenticity. On the other hand, it hints at the imaginary of a space in which people are freely able to experiment with embodied performances of their cultural capital. Thus, Gully Boy’s repurposing of Divine and Naezy’s music video, and appropriation of songs by several other rappers, offers an opportunity to simultaneously examine the histories and politics that are at risk of seeping out through the cracks of such an articulation, and the spaces and communities created by this movement. This paper examines Gully Boy to follow the movement of images from counter-culture into the mainstream, and chart the consequences of this translation on the political identity of these images.

description: In this paper, we provide a survey on automotive surround-view fisheye optics, with an emphasis on the impact of optical artifacts on computer vision tasks in autonomous driving and ADAS. The automotive industry has advanced in applying state-of-the-art computer vision to enhance road safety and provide automated driving functionality. When using camera systems on vehicles, there is a particular need for a wide field of view to capture the entire vehicle's surroundings, in areas such as low-speed maneuvering, automated parking, and cocoon sensing. However, one crucial challenge in surround-view cameras is the strong optical aberrations of the fisheye camera, which is an area that has received little attention in the literature. Additionally, a comprehensive dataset is needed for testing safety-critical scenarios in vehicle automation. The industry has turned to simulation as a cost-effective strategy for creating synthetic datasets with surround-view camera imagery. We examine different simulation methods (such as model-driven and data-driven simulations) and discuss the simulators' ability (or lack thereof) to model real-world optical performance. Overall, this paper highlights the optical aberrations in automotive fisheye datasets, and the limitations of optical reality in simulated fisheye datasets, with a focus on computer vision in surround-view optical systems.

description: Fortelling er kunsten å fortelle historier for å formidle erfaringer, ideer, tanker og verdier på en engasjerende måte. I stedet for bare å presentere kunnskap eller informasjon, inneholder historier menneskelige og relaterbare elementer som resonnerer med publikum på et emosjonelt og personlig nivå. Dette fremmer empati, medfølelse og etablerer en felles forståelse.

Klimafortellinger bruker fortelling for å kommunisere temaer knyttet til klimaendringer. For mange føles klimaendringer abstrakte, fjerne og komplekse, noe som gjør det vanskelig å informere, utdanne eller engasjere dem på en måte som virkelig treffer. Fortelling gjør det mulig å formidle kompleks vitenskapelig data, modellresultater og kunnskap til den tiltenkte målgruppen. Denne tilnærmingen bidrar til å "bygge bro" mellom vitenskap og samfunn.

Denne praktiske veiledningen støtter klima-tilpasningspraktikere i å utvikle sine egne klimafortellinger med mål om å øke bevisstheten om klimatrusler og planlagte løsninger, eller motivere folk til å handle. Veiledningen er utviklet som en del av det europeiske forskningsprosjektet REACHOUT, der en metode for klimafortellinger ble utviklet, evaluert og forbedret. Eksempler fra seks europeiske byer i dette prosjektet fremheves gjennom veiledningen.

description: Roughly ten years ago, the following "Gorenstein Interval Conjecture" (GIC) was proposed: Whenever $(1,h_1,\dots,h_i,\dots,h_{e-i},\dots,h_{e-1},1)$ and $(1,h_1,\dots,h_i+α,\dots,h_{e-i}+α,\dots,h_{e-1},1)$ are both Gorenstein Hilbert functions for some $α\geq 2$, then $(1,h_1,\dots,h_i+β,\dots,h_{e-i}+β,\dots,h_{e-1},1)$ is also Gorenstein, for all $β=1,2,\dots,α-1$. Since an explicit characterization of which Hilbert functions are Gorenstein is widely believed to be hopeless, the GIC, if true, would at least provide the existence of a strong, and very natural, structural property for such basic functions in commutative algebra. Before now, very little progress was made on the GIC. The main goal of this note is to prove the case $e\le 5$, in arbitrary codimension. Our arguments will be in part constructive, and will combine several different tools of commutative algebra and classical algebraic geometry.

description: We study a two-parameter family of quantum spin systems on the complete graph, which is the most general model invariant under the complex orthogonal group. In spin $S=\frac{1}{2}$ it is equivalent to the XXZ model, and in spin $S=1$ to the bilinear-biquadratic Heisenberg model. The paper is motivated by the work of Björnberg, whose model is invariant under the (larger) complex general linear group. In spin $S=\frac{1}{2}$ and $S=1$ we give an explicit formula for the free energy for all values of the two parameters, and for spin $S>1$ for when one of the parameters is non-negative. This allows us to draw phase diagrams, and determine critical temperatures. For spin $S=\frac{1}{2}$ and $S=1$, we give the left and right derivatives as the strength parameter of a certain magnetisation term tends to zero, and we give a formula for a certain total spin observable, and heuristics for the set of extremal Gibbs states in several regions of the phase diagrams, in the style of a recent paper of Björnberg, Fröhlich and Ueltschi. The key technical tool is expressing the partition function in terms of the irreducible characters of the symmetric group and the Brauer algebra. The parameters considered include, and go beyond, those for which the systems have probabilistic representations as interchange processes.

description: Fortelling er kunsten å fortelle historier for å formidle erfaringer, ideer, tanker og verdier på en engasjerende måte. I stedet for bare å presentere kunnskap eller informasjon, inneholder historier menneskelige og relaterbare elementer som resonnerer med publikum på et emosjonelt og personlig nivå. Dette fremmer empati, medfølelse og etablerer en felles forståelse.

Klimahistorier bruker fortelling for å kommunisere temaer knyttet til klimaendringer. For mange føles klimaendringer abstrakte, fjerne og komplekse, noe som gjør det vanskelig å informere, utdanne eller engasjere dem på en måte som virkelig treffer. Fortelling gjør det mulig å formidle kompleks vitenskapelig data, modellresultater og kunnskap til den tiltenkte målgruppen. Denne tilnærmingen bidrar til å "bygge bro" mellom vitenskap og samfunn.

Denne praktiske veiledningen støtter klima-tilpasningspraktikere i å utvikle sine egne klimahistorier med mål om å øke bevisstheten om klimatrusler og planlagte løsninger, eller motivere folk til å handle. Veiledningen er utviklet som en del av det europeiske forskningsprosjektet REACHOUT, der en metode for klimahistorier ble utviklet, evaluert og forbedret. Eksempler fra seks europeiske byer i dette prosjektet fremheves gjennom veiledningen.
The Baffling Semileptonic Branching Ratio of $B$ Mesons

description: The apparent gap between the measured and the expected value for the semileptonic branching ratio of $B$ mesons has become more serious over the last year. This is due to the improved quality of the data and to the increasing maturity of the theoretical treatment of non-perturbative corrections. We discuss various theoretical options to reduce the semileptonic $B$ branching ratio; among the more spectacular resolutions of the apparent puzzle is the possibility of an unorthodox enhancement in non-perturbative corrections or even of an intervention by `New Physics'. Phenomenological implications of such scenarios are pointed out.

Nonequilibrium dynamics of superconductivity in the attractive Hubbard model

description: We present a framework of semiclassical superconductivity (SC) dynamics that properly includes effects of spatial fluctuations for the attractive Hubbard model. We consider both coherent and adiabatic limits. To model the coherent SC dynamics, we develop a real-space von~Neumann equation based on the time-dependent Hartree-Fock-Bogoliubov theory. Applying our method to interaction quenches in the negative-$U$ Hubbard model, we show that the relaxation of SC order at weak coupling is dominated by Landau-damping. At strong coupling, we find a two-stage relaxation of the pairing field: a collapse of the synchronized oscillation of Cooper pairs due to spatial inhomogeneity, followed by a slow relaxation to a quasi-stationary state. SC dynamics in adiabatic limit is described by a quantum Landau-Lifshitz equation with Ginzburg-Landau relaxation. Numerical simulations of the pump-probe process show that long time recovery of the pairing field is dominated by defects dynamics. Our results demonstrate the important role of spatial fluctuations in both limits.

description: Throughout history, the public image of the female politician has been influenced by the notion that the identity of a ‘politician’ is male. The female body enters into the representational “space” of a rhetorical event as it is limited by a masculine structure (de Beauvoir 1407). Since politicians are still subject to the limitations of engendered language, a woman in the public sphere must embrace the masculine image of the politician, while still identifying herself as a woman in order to gain respect and social acceptance. However, by adopting a masculine image, women can run the risk of upsetting gender roles and possibly threatening masculinity itself. If women are becoming more masculine in order to find their place in politics, what then becomes of the ‘male’ politicians?
This is How We See the War: Counter-narratives of the Conflict in Contemporary Jihadist Visuality

description: Contemporary warfare, especially from a Western point of view, is more and more an issue of distance, surgical strikes, machine vision and collateral damages. This image of a technical and “clean” war has been largely criticized from a theoretical point of view by the forensic approach promoted by Weizman. In his inspections in war zones, he stresses the importance of a new sensibility towards the indexical nature of photography, promoting the necessity of a counter-narrative towards the Western ideology of war. After addressing these theoretical issues in the context of the contemporary debate in image theory, the essay will focus on how contemporary jihadism ends up adopting the same approach towards images, in order to produce a personal and specific counter-narrative of warfare. The re-appropriation of Western war images and the production of specific visual outputs by groups such as the so-called Islamic State, has a strong political value. This will be demonstrated analyzing images and videos produced by the Islamic State that are largely unknown to the Western public. Here IS’ shows a different face of contemporary warfare, constructing a complex and multi-layered counter-narrative that focuses on concepts such as victimhood and brutality.

Boundary conditions for Dirac fermions on a terminated honeycomb lattice

description: We derive the boundary condition for the Dirac equation corresponding to a tight-binding model on a two-dimensional honeycomb lattice terminated along an arbitary direction. Zigzag boundary conditions result generically once the boundary is not parallel to the bonds. Since a honeycomb strip with zigzag edges is gapless, this implies that confinement by lattice termination does not in general produce an insulating nanoribbon. We consider the opening of a gap in a graphene nanoribbon by a staggered potential at the edge and derive the corresponding boundary condition for the Dirac equation. We analyze the edge states in a nanoribbon for arbitrary boundary conditions and identify a class of propagating edge states that complement the known localized edge states at a zigzag boundary.

Energy-Efficient User Access Control and Resource Allocation in HCNs with Non-Ideal Circuitry

description: In this paper, we study the energy-efficient user access control (UAC) based on resource allocation (RA) in heterogeneous cellular networks (HCNs) with the required downlink data rate under non-ideal power amplifiers (PAs) and circuit power. It is proved that the energy consumption minimization is achieved when the typical user accesses only one base station (BS), while the other BSs remain in idle mode on the transmission resource allocated to this user. For this purpose, we reformulate the original non-convex optimization problem into a series of convex optimization problems where, in each case, the transmit power and duration of the accessed BS are determined. Then, the BS with the minimal energy consumption is selected for transmission. Considering the approximate situation, it is showed that the optimal transmit duration of the accessed BS can be estimated in closed form. The benefits of our proposed UAC and RA schemes are validated using numerical simulations, which also characterize the effect that non-ideal PAs have on the total energy consumption of different transmission schemes.

Effects of underlying topology on quantum state discrimination

description: In this work, we show that quantum state discrimination can be modified due to a change in the underlying topology of a system. In particular, we explicitly demonstrate that the quantum state discrimination of systems with underlying discrete topology differs from that of systems with underlying continuous topology. Such changes in the topology of a spacetime can occur in certain quantum gravity approaches. In fact, all approaches to quantum gravity can be classified into two types: those with underlying continuous topology (such as string theory) and those with an underlying discrete topology (such as loop quantum gravity). We demonstrate that the topology of these two types of quantum gravity approaches has different effects on the quantum state discrimination of low-energy quantum systems. We also show that any modification of quantum mechanics, which does not change the underlying topology, does not modify quantum state discrimination.
