description: Most of the Milky Way's evolved massive stellar population is hidden from view. We can attempt to remedy this situation with near-infrared observations, and in this paper we present our method for detecting Wolf-Rayet stars in highly extincted regions and apply it to the inner Galaxy. Using narrow band filters at K-band wavelengths, we demonstrate how WR stars can be detected in regions where they are optically obscured. Candidates are selected for spectroscopic follow-up from our relative line and continuum photometry. The final results of applying this method with a NIR survey in the Galactic plane will provide a more complete knowledge of the structure of the galactic disk, the role of metallicity in massive stellar evolution, and environments of massive star formation. In this paper we briefly describe the survey set-up and report on recent progress. We have discovered four emission-line objects in the inner Galaxy: two with nebular emission lines, and two new WR stars, both of late WC subtype.

description: This study adapts Semantic Network of Adposition and Case Supersenses (SNACS) annotation to Mandarin Chinese and demonstrates that the same supersense categories are appropriate for Chinese adposition semantics. We annotated 15 chapters of The Little Prince, with high interannotator agreement. The parallel corpus gives insight into differences in construal between the two languages' adpositions, namely a number of construals that are frequent in Chinese but rare or unattested in the English corpus. The annotated corpus can further support automatic disambiguation of adpositions in Chinese, and the common inventory of supersenses between the two languages can potentially serve cross-linguistic tasks such as machine translation.

description: Spatial transformer network has been used in a layered form in conjunction with a convolutional network to enable the model to transform data spatially. In this paper, we propose a combined spatial transformer network (STN) and a Long Short-Term Memory network (LSTM) to classify digits in sequences formed by MINST elements. This LSTM-STN model has a top-down attention mechanism profit from LSTM layer, so that the STN layer can perform short-term independent elements for the statement in the process of spatial transformation, thus avoiding the distortion that may be caused when the entire sequence is spatially transformed. It also avoids the influence of this distortion on the subsequent classification process using convolutional neural networks and achieves a single digit error of 1.6\% compared with 2.2\% of Convolutional Neural Network with STN layer.

description: The repton model is a simple model of the "reptation" motion by which DNA diffuses through a gel during electrophoresis. In this paper we show that the model can be mapped onto a system consisting of two types of particles with hard-sphere interactions diffusing on a one-dimensional lattice. Using this mapping we formulate an efficient Monte Carlo algorithm for the model which allows us to simulate systems more than twice the size of those studied before. Our results confirm scaling hypotheses which have previously been put forward for the model. We also show how the particle version of the model can be used to construct a transfer matrix which allows us to solve exactly for the diffusion constant of small repton systems. We give results for systems of up to 20 reptons.

description: Acoustic metamaterials are structures with exotic acoustic properties, having promising applications in acoustic beam steering, focusing, impedance matching, absorption and isolation. Recent work has shown that the efficiency of many acoustic metamaterials can be enhanced by controlling an additional parameter known as Willis coupling, which is analogous to bianisotropy in electromagnetic metamaterials. The magnitude of Willis coupling in an acoustic meta-atom has been shown theoretically to have an upper limit, however the feasibility of reaching this limit has not been experimentally investigated. Here we introduce a meta-atom with Willis coupling which closely approaches this theoretical limit, that is much simpler and less prone to thermo-viscous losses than previously reported structures. We perform two-dimensional experiments to measure the strong Willis coupling, supported by numerical calculations. Our meta-atom geometry is readily modeled analytically, enabling the strength of Willis coupling and its peak frequency to be easily controlled. Together with its ease of fabrication, this will facilitate the design of future high efficiency acoustic devices.

description: We study numerically and analytically the properties of the stationary state of a particle moving under the influence of an electric field $\bE$ in a two dimensional periodic Lorentz gas with the energy kept constant by a Gaussian thermostat. Numerically the current appears to be a continuous function of $\bE$ whose derivative varies very irregularly, possibly in a discontinuous manner. We argue for the non differentibility of the current as a function of $\bE$ utilizing a symbolic description of the dynamics based on the discontinuities of the collision map. The decay of correlations and the behavior of the diffusion constant are also investigated.

description: We report the presence of giant spontaneous exchange bias (HSEB) in a hard and soft antiferromagnetic composite of BiFeO3-TbMnO3 (BFO-TMO in 7:3 and 8:2 ratio). The HSEB varies between 5-778Oe, but persists up to room temperature with a maximum near a spin reorientation transition temperature observed from magnetization vs. temperature measurement in Zero-field cooled (ZFC) and Field cooled (FC) modes. Isothermal remnant magnetization measurements at room temperature indicate the presence of an interfacial layer of a 2 dimensional dilute antiferromagnet in a field (2D DAFF). A stable value of the exchange bias has been observed via training effect measurements which signify the role of interfacial exchange coupling in the system. Based on the experimental results we explain the presence of the giant spontaneous exchange bias on the basis of a strong strain-mediated magnetoelectriccoupling induced exchange interaction and the creation of 2D DAFF layer at the interface. Theproperties of this layer are defined by canting and pinning of BFO spins at the interface with TMO due to Fe and Mn interaction. X-ray Magnetic Circular Dichroism (XMCD) confirms the presence of canted antiferromagnetic ordering of BiFeO3, charge transfer between Mn ions and different magnetically coupled layers which play vital role in getting the exchange bias.

description: Due to the different losses caused by various photovoltaic (PV) array faults, accurate diagnosis of fault types is becoming increasingly important. Compared with a single one, multiple PV stations collect sufficient fault samples, but their data is not allowed to be shared directly due to potential conflicts of interest. Therefore, federated learning can be exploited to train a collaborative fault diagnosis model. However, the modeling efficiency is seriously affected by the model update mechanism since each PV station has a different computing capability and amount of data. Moreover, for the safe and stable operation of the PV system, the robustness of collaborative modeling must be guaranteed rather than simply being processed on a central server. To address these challenges, a novel asynchronous decentralized federated learning (ADFL) framework is proposed. Each PV station not only trains its local model but also participates in collaborative fault diagnosis by exchanging model parameters to improve the generalization without losing accuracy. The global model is aggregated distributedly to avoid central node failure. By designing the asynchronous update scheme, the communication overhead and training time are greatly reduced. Both the experiments and numerical simulations are carried out to verify the effectiveness of the proposed method.

description: The two-dimensional flows around a cylinder between two parallel walls at Re=40 and Re=100 are simulated with computational fluid dynamics (CFD). The governing equations are Navier-Stokes equations. They are discretized with finite volume method (FVM) and the solution is iterated with PISO Algorithm. Then, the calculating results are compared with the numerical results in literature, and good agreements are obtained. After that, the mechanism of the formation of Karman vortex street is investigated and the instability of the entire flow field is analyzed with the energy gradient theory. It is found that the two eddies attached at the rear of the cylinder have no effect on the flow instability for steady flow, i.e., they don't contribute to the formation of Karman vortex street. The formation of Karman vortex street originates from the combinations of the interaction of two shear layers at two lateral sides of the cylinder and the absolute instability in the cylinder wake. For the flow with Karman vortex street, the initial instability occurs at the region inner a vortex downstream of the wake and the center of a vortex firstly loses its stability inner a vortex. For pressure driven flow, it is confirmed that the inflection point on the time-averaged velocity profile leads to the instability. It is concluded that the energy gradient theory is potentially applicable to study the flow stability and to reveal the mechanism of turbulent transition.

description: Quantum canonical transformations corresponding to time-dependent diffeomorphisms of the configuration space are studied. A special class of these transformations which correspond to time-dependent dilatations is used to identify a previously unknown class of exactly solvable time-dependent harmonic oscillators. The Caldirola-Kanai oscillator belongs to this class. For a general time-dependent harmonic oscillator, it is shown that choosing the dilatation parameter to satisfy the classical equation of motion, one obtains the solution of the Schrödinger equation. A simple generalization of this result leads to the reduction of the Schrödinger equation to a second order ordinary differential equation whose special case is the auxiliary equation of the Lewis-Riesenfeld invariant theory. Time-evolution operator is expressed in terms of a positive real solution of this equation in a closed form, and the time-dependent position and momentum operators are calculated.

description: As human activities on the Moon expand through initiatives like NASA's Artemis program, the need for sustainable post-mission disposal strategies becomes critical to maintaining the lunar environment. This paper analyzes the logistics and environmental implications of waste products generated by In-Situ Resource Utilization technologies employed in oxygen production on the Moon. The study examines the inputs, generation of products, and the resulting byproducts from Molten Regolith Electrolysis, Soil/Water Extraction, and Direct Water Electrolysis systems. These technologies yield varied byproducts, including slag, metals and volatiles, each presenting unique challenges for disposal and recycling. The analysis assesses the economic and ecological impacts of In-Situ Resource Utilization activities on lunar operations using a multi-commodity flow model adapted from cislunar logistics frameworks. The results inform that ISRU-enabled missions achieve a significant threefold cost reduction. However, the management of byproducts remains a critical challenge, demanding innovative solutions to address their impact and support scalable and sustainable lunar exploration.

Somewhere in the Universe: Where is the Information Stored When Histories Decohere?

description: We investigate the idea that decoherence is connected with the storage of information about the decohering system somewhere in the universe. The known connection between decoherence of histories and the existence of records is extended from the case of pure initial states to mixed states. Records may still exist but are necessarily imperfect. We formulate an information-theoretic conjecture about decoherence due to an environment: the number of bits required to describe a set of decoherent histories is approximately equal to the number of bits of information thrown away to the environment in the coarse-graining process. This idea is verified in a simple model consisting of a particle coupled to an environment that can store only one bit of information. We explore the decoherence and information storage in the quantum Brownian motion model. It is shown that the variables that the environment naturally measures and stores information about are the Fourier components of the function $x(t)$ (describing the particle trajectory). The records storing the information about the Fourier modes are the positions and momenta of the environmental oscillators at the final time. Decoherence is possible even if there is only one oscillator in the environment. The information count of the histories and records in the environment add up according to our conjecture. These results give quantitative content to the idea that decoherence is related to ``information lost''.

description: This thesis presents the results of my angle-resolved photoemission (ARPES) study of the delafossite oxides PdCoO₂, PtCoO₂ and PdCrO₂ as well as delafossite-like AgCrSe₂. When cleaving the sample, their layered ABX₂ structure results in distinct surface terminations that are spatially distributed across the sample. These are either electron (A-termination) or hole doped (BX₂-termination) with respect to the bulk, resulting in their markedly different surface electronic structures. These electronic surface structures host a delicate interplay between the spin-, charge-, and orbital-degrees of freedom, driving the formation of new phases. The understanding of this interplay is the central concept of this thesis. Probing defined surface domains has often been challenging due to the beam spot of the incoming light being larger than a single domain. Here, I show that by using μ-ARPES, where the beam spot is focused to 4 μm, it is possible to probe the electronic structure of a distinct surface termination and study the extent of spatial variations in the electronic structure across the sample. Identifying areas of pristine terminations greatly increased the effective resolution, enabling the detailed study of the surface electronic structure. I show that PdCrO₂ undergoes a charge-order driven surface reconstruction that protects the insulating nature of the CrO₂ states at the surface. For PdCoO₂, I demonstrate strong electron-phonon coupling on both the CoO₂- and Pd-terminated surfaces, with an unusually strong coupling on the Pd-termination driving the formation of two distinct polaron modes. I conclude by presenting my study on non-centrosymmetric delafossite-like AgCrSe₂. Here, a delicate interplay between bulk and surface inversion symmetry breaking results in a Rashba-type splitting of the states derived from different magnetic domains. I will also revise the role of the subsurface layer for these systems which has thus far been widely neglected but is crucial to achieve an accurate description of the underlying physics.

description: Despite its potential for device application, the non-magnetic Zeeman effect has only been predicted and observed in two-dimensional compounds. We demonstrate that non-centrosymmetric three-dimensional compounds can also exhibit a Zeeman-type spin splitting, allowing the splitting control by changing the growth direction of slabs formed by these compounds. We determine the required conditions for this effect: $i$) non-centrosymmetric including polar and non-polar point groups, $ii$) valence band maximum or conduction band minimum in a generic $k$-point, i.e., non-time-reversal-invariant momentum, and $iii$) zero magnetic moment. Using these conditions as filters, we perform a material screening to systematically search for these systems in the aflow-ICSD database. We find 20 material candidates featuring the Zeeman-type effect. We also found that the spin-splitting in confined systems can be controlled by an external electric field, which in turns can induce a metal-insulator transition. We believe that the Zeeman-type effect in three-dimensional compounds can potentially be used for spin-filtering devices.

Ownerless artworks: an analysis of the Musée du Louvre's unpossessed possessions
Creators: name: Boutillier, Erin Virginia
Publisher: name: No Publisher Supplied
Year: 2021

description: The impact of the Third Reich’s large-scale art thefts across Europe during World War II are still being thoroughly examined in the modern day. France, in particular, was left with some 60,000 works that were destined to be repatriated to museums, Jewish families, Jewish art collectors, and various cultural institutions in the aftermath of the war. After much time was spent returning these works, the French state was left with about 2,000 pieces of art that had gone unclaimed. The Musée du Louvre was given just over 1,000 of the aforementioned works. Three years ago, in February of 2018, the Musée du Louvre presented the installation of a small, permanent gallery space that would display thirty-one of their MNR (Musées Nationaux Récupération) works. The curators that worked on the exhibition asserted that it would become a stage in which French Holocaust survivors could visit and potentially find (as well as reclaim) their stolen works. This thesis strives to determine whether or not a museum’s gallery spaces can function as a pathway to legitimate restitution of stolen and forced-sale artworks. Among the variety of points that will be touched upon in this thesis, the most critical is the ethical implication of such an exhibition, and if it is as accessible as the museum claims it to be. These queries will be disseminated through a methodological study of discourse analysis with specific focus on the system of archival silencing. In turn, the question is asked, does the exhibition, in its present format, allow for repatriation of cultural heritage objects or does it perpetuate the silences that are glaringly present in museum practices?

With a mass of ${\rm M}_{\star}$ = $1.284_{-0.016}^{+0.020}$ ${\rm M}_{J}$, a radius of ${\rm R}_{\star}$ = 2.314$_{-0.042}^{+0.049}$ ${\rm R_J}$, and an age of 4.7 $\pm$ 0.2 Gyr, the solar metallicity host star has already departed from the main sequence. We find evidence in the radial velocity measurements for a long term acceleration, and a $P \approx 18$ d periodic signal that we attribute to rotational modulation by stellar activity. The HD1397 system is among the brightest systems currently known to host a transiting planet, which will make it possible to perform detailed follow-up observations in order to characterize the properties of giant planets orbiting evolved stars.

The Object-Gaze: Shame, Hejab, Cinema
Creators: name: Copjec, Joan
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2006

description: The method for torturing prisoners at Abu Ghraib was chosen because it was assumed that the Islamic modesty system, or hejab, makes Muslims especially vulnerable to shame. Through an examination of the films of the Iranian filmmaker, Abbas Kiarostami, who directs films under the censorship rules imposed by hejab, and an examination of the philosoph­ical and psychoanalytic literature on shame, this paper calls into ques­tion both the assumption of the torturers and many of the restraints of the modesty system.

"The Roma Do Not Exist": The Roma as an Object of Cinematic Representation and the Question of Authenticity
Creators: name: Homer, Sean
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2006

description: Representations of the Roma are ubiquitous in the history of Balkan cin­ema. These films have tended to be by non-Roma directors, with the Ro­ma as the object of representation. Consequently, the critical reception of the films has focused on the issue of verisimilitude. In recent scholarship critics have utilized the psychoanalytic concept of "projective identifica­tion" to account for the persistent interest in Gypsy culture and life. In this paper I draw on an alternative tradition of Lacanian psychoanalysis to argue that Tony Gatlif's Gadjo dilo, rather than presenting an authen­tic picture of Roma culture, foregrounds the impossibility of representa­tion ever truthfully capturing the object. Deploying the Lacanian con­cepts of das Ding and "The Woman does not exist," the paper demon­strates how Gatlif problematises the very notion of the Roma as a ho­mogenized culture and identity.

An examination of cardiac vagal control indices and cognitive stress appraisal in cigarette smokers
Creators: name: Brinkman, Hannah Rose
Publisher: name: No Publisher Supplied
Year: 2021

description: Cigarette smokers represent a vulnerable group for mounting a dysregulated stress response. One predominant determinant of the stress response is the autonomic nervous system’s ability to flexibly shift between arousal and rest states largely driven by the interplay between the sympathetic and parasympathetic nervous system branches. Cardiac vagal control (CVC) has been cited as one measure of autonomic flexibility with evidence suggesting that greater CVC is associated with more adaptive functioning and flexible emotional responding. However few studies have examined how measures of CVC relate to regulatory processes implicated in smoker stress-responsivity. The primary aim of this study sought to explore how two indices of CVC relate to smoker threat appraisal in response to a laboratory stress test. Sixty cigarette smokers underwent a modified trier social stress test during which they gave an impromptu speech to a panel of evaluators while unknowingly randomized to receive positive or negative social feedback. Resting and reactivity measures of CVC were computed, along with a post-task threat appraisal index reflecting the ratio of how demanding participants perceived the task to be relative to their available coping resources. In efforts to build off the exploratory nature of our first aim, we also examined whether social feedback condition moderated the effect of CVC on post-task threat appraisal. In contrast to previous empirical findings from healthy samples, we found no significant main or interactive effects of CVC indices and feedback condition on smoker post-task threat appraisal. Findings from this study have several implications when considering the relationship between these variables in smokers and can be used to inform future investigative efforts.

description: We report intrinsic spin decay length of an antiferromagnetic insulator. We found that at an antiferromagnetic/ferromagnetic interface, a spin current generated by spin pumping is strongly suppressed by two-magnon scattering. By eliminating the two-magnon contribution, we discovered that the characteristic length of spin decay in NiO changes by two-orders of magnitude through the paramagnetic to antiferromagnetic transition. The spin decay length in the antiferromagnetic state is longer than 100 nm, which is an order of magnitude longer than previously believed. These results provide a crucial piece of information for the fundamental understanding of the physics of spin transport.
Stationary Nonequilibrium States in Boundary Driven Hamiltonian Systems: Shear Flow

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We investigate stationary nonequilibrium states of systems of particles moving according to Hamiltonian dynamics with specified potentials. The systems are driven away from equilibrium by Maxwell demon ``reflection rules'' at the walls. These deterministic rules conserve energy but not phase space volume, and the resulting global dynamics may or may not be time reversible (or even invertible). Using rules designed to simulate moving walls we can obtain a stationary shear flow. Assuming that for macroscopic systems this flow satisfies the Navier-Stokes equations, we compare the hydrodynamic entropy production with the average rate of phase space volume compression. We find that they are equal when the velocity distribution of particles incident on the walls is a local Maxwellian. An argument for a general equality of this kind, based on the assumption of local thermodynamic equilibrium, is given. Molecular dynamic simulations of hard disks in a channel produce a steady shear flow with the predicted behavior.

Filming the Dutch Still Life: Peter Greenaway's Objects
Creators: name: Karastathi, Sylvia
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2006

description: This article examines the symbolic and visual function of objects in four of Peter Greenaway's films made in the 1980s, a period when the film­maker was exploring the relation between cinema and painting. It traces his references to the objects of seventeenth-century Dutch still life paint­ing and, informed by art-historical criticism on the subject, argues for the objects' multivalent nature, varying from symbols and allegories to vi­sual and material props. His treatment of decay and his study of the hu­man dependence on material culture in films like A Zed and Two Noughts and Drowning by Numbers have their visual origins in the images of Dutch still life. In true Dutch mode Greenaway employs fruits, flowers and food in order to shift subject/object hierarchies and foreground the material aspect of being human.

Prepare for Trouble and Make it Double. Supervised and Unsupervised Stacking for AnomalyBased Intrusion Detection

description: In the last decades, researchers, practitioners and companies struggled in devising mechanisms to detect malicious activities originating security threats. Amongst the many solutions, network intrusion detection emerged as one of the most popular to analyze network traffic and detect ongoing intrusions based on rules or by means of Machine Learners (MLs), which process such traffic and learn a model to suspect intrusions. Supervised MLs are very effective in detecting known threats, but struggle in identifying zero-day attacks (unknown during learning phase), which instead can be detected through unsupervised MLs. Unfortunately, there are no definitive answers on the combined use of both approaches for network intrusion detection. In this paper we first expand the problem of zero-day attacks and motivate the need to combine supervised and unsupervised algorithms. We propose the adoption of meta-learning, in the form of a two-layer Stacker, to create a mixed approach that detects both known and unknown threats. Then we implement and empirically evaluate our Stacker through an experimental campaign that allows i) debating on meta-features crafted through unsupervised base-level learners, ii) electing the most promising supervised meta-level classifiers, and iii) benchmarking classification scores of the Stacker with respect to supervised and unsupervised classifiers. Last, we compare our solution with existing works from the recent literature. Overall, our Stacker reduces misclassifications with respect to (un)supervised ML algorithms in all the 7 public datasets we considered, and outperforms existing studies in 6 out of those 7 datasets. In particular, it turns out to be more effective in detecting zero-day attacks than supervised algorithms, limiting their main weakness but still maintaining adequate capabilities in detecting known attacks.
