Subjects: corpus
Sanskrit
Buddhist Sanskrit

description: This is a proof-of-concept Sanskrit corpus developed for the study of Buddhist Sanskrit lexicology. It comprises: 102 metadata-enriched Buddhist Sanskrit texts for a total of ~ 3.5 million tokens a 4 million tokens reference corpus comprising 30 metadata-enriched non-Buddhist Sanskrit texts. The corpus is in romanised Sanskrit (UTF-8 encoding) and is available in three configurations: segmented (with dash-separated words) segmented and stemmed (with capitalised word stem and compounds separated by an @ sign). segmented, stemmed and normalised (normalisation treats some spelling variation and solves sandhi of stems' initials in most cases), recommended for Word Sketches. The latter version can be used to generate word sketches in Sketch Engine if used in conjunction with the included sketch grammar, which infers likely syntactic dependencies from morphological cues. Limitations
 As a proof of concept, this corpus suffers from several limitations. It is very small by contemporary standards, it has not been proof-read and it is currently only segmented and stemmed (not lemmatised or PoS tagged).
 A funding bid has been submitted to expand and lemmatise the corpus. Data Quality
 The corpus has been segmented with Lugli's Sanskrit segmenter (10.5281/zenodo.3459215). The accuracy of this segmenter has been evaluated at 97% on a sample of Buddhist Sanskrit literature. No evaluation has been performed on non-Buddhist materials and the quality of the segmentation may be worse in the non-Buddhist section of the corpus. Acknowledgments
 The corpus has been realised as part of the project 'Lexis and Tradition: variation in the vocabulary of Sanskrit Mahāyāna literature'. This project was funded by the British Academy through a Newton International Fellowship (NF161436) and hosted at the Department of Theology and Religious Studies at King's College London under the supervision of Prof. Henrietta Kate Crosby. Thanks to GRETIL, Dr. Vinita Tseng and Prof. Steinkellner for kindly giving their permission to include automatically processed versions of some of their editions in this corpus.

description: We study correlations between geometric subfactors living on the Ryu-Takayanagi surface that bounds the entanglement wedge. Using the surface-state correspondence and the bit threads program, we are able to calculate mutual information and conditional mutual information between subfactors. This enables us to count the shared Bell pairs between subfactors, and we propose an entanglement distillation procedure over these subsystems via a SWAP gate protocol. We comment on extending to multipartite entanglement.

description: The City of Tucson has proposed to develop part of a commercial block, Historic Block 208, also known as the Thrifty Block, in downtown Tucson, Pima County, Arizona. Three parcels within the block had been razed prior to the current project. Archival research indicated that Historic Block 208 had a long history of both residential and commercial use, and that intact subsurface archaeological deposits could be expected within the project area. A testing and data recovery plan was proposed (Diehl 2006). Testing and data recovery were conducted by Desert Archaeology, Inc., in July 2006, and required 4 person-days to complete. A total of 41 m of backhoe trench was excavated during testing, and four features were identified. One feature was completely excavated during data recovery. The details and findings of the testing and data recovery plan at Historic Block 208 are presented in this report, and recommendations are provided.
Conformal Symmetry and Differential Regularization of the Three-Gluon Vertex

description: The conformal symmetry of the QCD Lagrangian for massless quarks is broken both by renormalization effects and the gauge fixing procedure. Renormalized primitive divergent amplitudes have the property that their form away from the overall coincident point singularity is fully determined by the bare Lagrangian, and scale dependence is restricted to $δ$-functions at the singularity. If gauge fixing could be ignored, one would expect these amplitudes to be conformal invariant for non-coincident points. We find that the one-loop three-gluon vertex function $Γ_{μνρ}(x,y,z)$ is conformal invariant in this sense, if calculated in the background field formalism using the Feynman gauge for internal gluons. It is not yet clear why the expected breaking due to gauge fixing is absent. The conformal property implies that the gluon, ghost and quark loop contributions to $Γ_{μνρ}$ are each purely numerical combinations of two universal conformal tensors $D_{μνρ}(x,y,z)$ and $C_{μνρ}(x,y,z)$ whose explicit form is given in the text. Only $D_{μνρ}$ has an ultraviolet divergence, although $C_{μνρ}$ requires a careful definition to resolve the expected ambiguity of a formally linearly divergent quantity. Regularization is straightforward and leads to a renormalized vertex function which satisfies the required Ward identity, and from which the beta-function is easily obtained. Exact conformal invariance is broken in higher-loop orders, but we outline a speculative scenario in which the perturbative structure of the vertex function is determined from a conformal invariant primitive core by interplay of the renormalization group equation and Ward identities.

Local Optimality and Generalization Guarantees for the Langevin Algorithm via Empirical Metastability

description: We study the detailed path-wise behavior of the discrete-time Langevin algorithm for non-convex Empirical Risk Minimization (ERM) through the lens of metastability, adopting some techniques from Berglund and Gentz (2003. For a particular local optimum of the empirical risk, with an arbitrary initialization, we show that, with high probability, at least one of the following two events will occur: (1) the Langevin trajectory ends up somewhere outside the $\varepsilon$-neighborhood of this particular optimum within a short recurrence time; (2) it enters this $\varepsilon$-neighborhood by the recurrence time and stays there until a potentially exponentially long escape time. We call this phenomenon empirical metastability. This two-timescale characterization aligns nicely with the existing literature in the following two senses. First, the effective recurrence time (i.e., number of iterations multiplied by stepsize) is dimension-independent, and resembles the convergence time of continuous-time deterministic Gradient Descent (GD). However unlike GD, the Langevin algorithm does not require strong conditions on local initialization, and has the possibility of eventually visiting all optima. Second, the scaling of the escape time is consistent with the Eyring-Kramers law, which states that the Langevin scheme will eventually visit all local minima, but it will take an exponentially long time to transit among them. We apply this path-wise concentration result in the context of statistical learning to examine local notions of generalization and optimality.

description: We have studied the properties of hot $^{234,236}$U and $^{240}$Pu nuclei in the framework of relativistic mean field formalism. The recently developed FSUGarnet and IOPB-I parameter sets are implemented for the first time to deform nuclei at finite temperature. The results are compared with the well-known NL3 set. The said isotopes are structurally important because of the thermally fissile nature of $^{233,235}$U and $^{239}$Pu as these nuclei ($^{234,236}$U and $^{240}$Pu) are formed after the absorption of a thermal neutron, which undergoes fission. Here, we have evaluated the nuclear properties, such as shell correction energy, neutron-skin thickness, quadrupole and hexadecapole deformation parameters and asymmetry energy coefficient for these nuclei as a function of temperature.

Speech Enhancement Using Deep Neural Networks
Creators: name: Xia, Yangyang
Publisher: name: Carnegie Mellon University
Year: 2024
Subjects: Computer Engineering

description:  Speech enhancement algorithms aim to improve the quality and intelligibility of speech signals degraded by noise to improve human or machine interpretation of speech. Thanks to large-scale datasets and online simulation, supervised algorithms based on deep neural networks can accurately suppress non-stationary noise, making them useful in practice for real-time communication systems and as the front end of automatic speech recognition systems. Despite all the advances, the extent to which these algorithms are robust to adverse acoustic conditions and phonetic categories of speech stimuli is still being investigated.
 This thesis addresses supervised speech enhancement in three parts. First, we describe the four-region error that serves as a diagnostic tool for speech enhancement algorithms. Compared to popular perceptual measures of speech quality, the four-region error distinguishes between two universal problems: under-suppression and over-suppression. We will show that all algorithms exhibit a trade-off between these error types and describe loss functions that balance the two. Second, we address the under-suppression problem within the frequency-domain speech enhancement framework. In the domain of instantaneous signal-to-noise ratio (ISNR), we unify algorithms trained on different targets. We will show that all methods face inevitable uncertainties as the ISNR decreases. We then introduce uncertainty learning that quantifies these uncertainties and improves noise reduction capability. Third, we address the over-suppression problem by incorporating phonetic information into the supervised framework. Through measurements of phonetically-dependent four-region error, we identify the over-suppression problem in obstruents in American English as the critical challenge of frequency-domain algorithms. We further identify a class of time-domain algorithms that exhibit different trade-offs and use them to train a phonetic segregation network. Finally, we explore phonetically-dependent channel selection rules to improve automatic speech recognition accuracy.

description: The number of sampling methods could be daunting for a practitioner looking to cast powerful machine learning methods to their specific problem. This paper takes a theoretical stance to review and organize many sampling approaches in the ``generative modeling'' setting, where one wants to generate new data that are similar to some training examples. By revealing links between existing methods, it might prove useful to overcome some of the current challenges in sampling with diffusion models, such as long inference time due to diffusion simulation, or the lack of diversity in generated samples.

The Visit of Prof. Hideki Yukawa to Kochi to Attend the Unveiling Ceremony of the Yukawa Bronze Statue: Turning Point in Life
Creators: name: Ohkubo, Shigeo
Publisher: name: arXiv
Year: 2022
Subjects: subject: History and Philosophy of Physics (physics.hist-ph)

description: We have discovered unknown very valuable old photos of Prof. Hideki Yukawa at the unveiling ceremony of his bronze statue at an elementary school in Kochi in 1954. The statue was moved to a newly created garden in1982, which in the subsequent decades accelerated the forgetting of its existence. The forgetting of the statue by the local people is related by chance to a historic event in the Marshall Islands. Prof. Yukawa's visit to attend the unveiling ceremony occurred just after news that Japanese fishermen were heavily injured by atomic testing at the Bikini Atoll in the Pacific Ocean. At the news conference when he arrived at Kochi, he was unexpectedly asked about his attitude to the bomb testing by the US. He was considered to be the foremost top scientist in nuclear science in Japan at that time, having been awarded the Nobel Prize for physics in 1949. People in Kochi were very anxious about the test since many fishermen worked near Bikini Atoll. Contrary to the expectation of local people, he refused to comment on the matter at the news conference and in public lectures, which were held several times during his stay in Kochi. After returning to Kyoto, he issued the famous statement titled Nuclear Era and the Turning Point of Mankind in an influential national newspaper. This was a time in Prof. Yukawa's life when he had to reflect and consult his conscience, and he chose to take a principled stance that became a turning point in his life. After the visit to Kochi, he devoted himself with his wife to the peace movement against nuclear weapons. Looking back, it can be observed that the visit in 1954 to attend the unveiling ceremony of his bronze statue in Kochi marked the start of that change. The statue can be seen to symbolize not only his Nobel Prize but also the turning point in his life that led him to support the peace movement against nuclear weapons.

description: Motivated by the recently developed classical spin model for Migdal-Eliashberg theory, we develop new numerical and analytical methods based on this spin-chain representation and apply these methods to the Bogoliuov-Tomachov-Morel-Anderson pairing potential, which incorporates the phonon-mediated attraction and Coulomb repulsion. We show that the Monte Carlo method with heat bath updates can efficiently obtain the gap functions even for the situations challenging for the iterative solvers, suggesting an unprecedented robust approach for solving the full nonlinear Migdal-Eliashberg theory. Moreover, we derive the renormalization of all the couplings by tracing out the high-frequency spins in the partition function. The derived analytical renormalization equations produce the well-known $μ^*$ effect for the Bogoliuov-Tomachov-Morel-Anderson pairing potential and can be generalized to other superconductivity problems. We further point out that several interesting features (e.g., sign changing in the frequency-dependent gap function) can be intuitively understood using the classical spin-chain representation for Migdal-Eliasherg theory. Our results show the advantage of using the spin-chain representation for solving Migdal-Eliashberg theory and provide new ways for tackling general superconductivity problems.

Cm$^{15+}$ and Bk$^{16+}$ ion clocks with enhanced sensitivity to new physics

description: We perform calculations of electronic structure of Cm$^{15+}$ and Bk$^{16+}$ ions and demonstrate that they have transitions which combine the features of atomic optical clocks with the enhanced sensitivity to the variations of the fine structure constant $α$. The high sensitivity is due to large nuclear charge $Z$, high ionisation degree $Z_i$ and the effect of {\em level crossing}, which enables optical transitions between states of different configurations. These are the $6p_{1/2}-5f_{5/2} $ and $6p_{1/2}-5f_{7/2} $ transitions in the single valence electron approximation. Variation of $α$ may be due to the interaction with scalar and pseudoscalar (axion) dark matter fields. Therefore, Cm$^{15+}$ and Bk$^{16+}$ clocks are promising candidates to search for these fields.

description: In this work, we made an extensive study about the possible presence of anisotropies in strange stars. To accomplish this task, we use three different configurations for the strange matter: the unpaired matter, a two-flavor super-conducting (2SC) strange matter, and a fully three-flavor super-conducting strange matter (CFL). For each configuration, we calculate the relevant quantities for the strange stars, such as the mass-radius relation, the dimensionless tidal parameter, the moment of inertia, and the surface curvature for different degrees of anisotropies. Whenever possible, we compare our results with constraints found in the literature, especially focusing on the existence of very massive pulsars (PSR J0952-0607), as well as very light compact objects (HESS J1731-347).

description: Recently, the semiclassical theory of the anomalous Hall effect induced by the Berry curvature in Bloch bands has been introduced. The theory operates only with gauge invariant concepts, that have a simple semiclassical interpretation and provides a clear distinction among various contributions to the Hall current. While the construction of such an approach to the anomalous Hall effect problem has been long sought, only the new semiclassical theory demonstrated the agreement with quantitative results of rigorous approaches based on the Green function techniques. The purpose of this work is to review the semiclassical approach including the early ideas and the recent achievements.

Long-range Coulomb Interaction effects on Topological Phase Transitions between Semi-metals and Insulators

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: Topological states may be protected by a lattice symmetry in a class of topological semi-metals. In three spatial dimensions, the Berry flux around gapless excitations in momentum space defines a chirality concretely, so a protecting symmetry may be referred to as a chiral symmetry. Prime examples include Dirac semi-metal (DSM) in a distorted spinel, BiZnSiO$_4$, protected by a mirror symmetry and DSM in Na$_3$Bi, protected by a rotational symmetry. In these states, topology and a chiral symmetry are intrinsically tied. In this work, we investigate characteristics interplay between a chiral symmetry order parameter and instantaneous long-range Coulomb interaction with the standard renormalization group method. We show that a topological transition associated with a chiral symmetry is stable under the presence of the Coulomb interaction and the electron velocity always becomes faster than one of a chiral symmetry order parameter. Thus, the transition {\it must not} be relativistic, which implies a supersymmetry is intrinsically forbidden by the long-range Coulomb interaction. {Asymptotically exact} universal ratios of physical quantities such as energy gap ratio are obtained, and connections with experiments and recent theoretical proposals are also discussed.

description: We link the lack of FR I type structure among quasars to the void of radio loud quasars below a critical disk luminosity of ~10^46 erg/sec in the PG sample. We argue that the opening angle of the obscuring torus in radio loud quasars depends on the power of the central engine, approaching the jet's beaming angle near the FR I/FR II break. Consequently, low power radio quasars would either be classified as radio galaxies (FR I) or strongly core-boosted (BL Lac) object, depending on the aspect angle, and no conspicuous transitional population would be expected for FR I sources. A closing torus with decreasing power would not only obscure the optical nucleus for most aspect angles but would also enhance the entrainment of the cool torus material into the jet stream, causing obscuration along the jet's periphery, as well as the jet's deceleration to form a FR I source. Above a critical luminosity, the wider torus allows for FR II type jets and visibility of the nuclear optical emission, characteristic of radio loud quasars. Apparently, at the same engine power the torus opening in radio weak quasars and Seyferts is substantially wider than in radio loud quasars, probably because of different dynamics or feeding mechanisms in disk and elliptical galaxies. This provides a clue for the radio-loud/radio-quiet dichotomy of quasars if the the jet/torus interaction leads to injection of relativistic e^+/- pairs via p-p collisions. Strong jet/torus interaction may lead to a substantial injection of secondary pairs and collimation in radio loud quasars, while weak interaction in radio weak quasars leads neither to pair injection nor to good collimation.

description: One of the goals of Space Weather studies is to achieve a better understanding of impulsive phenomena, such as Coronal Mass Ejections (CMEs), in order to improve our ability to forecast them and mitigate the risk to our technologically driven society. The essential part of achieving this goal is to assess the performance of forecasting models. To this end, the quality and availability of suitable data are of paramount importance. In this work, we have merged already publicly available data of CMEs from both in-situ and remote instrumentation in order to build a database of CME properties. To evaluate the accuracy of such a database and confirm the relationship between in-situ and remote observations, we have employed the drag-based model (DBM) due to its simplicity and inexpensive cost of computational resources. In this study, we have also explored the parameter space for the drag parameter and solar wind speed using a Monte Carlo approach to evaluate how well the DBM determines the propagation of CMEs for the events in the dataset. The dataset of geoeffective CMEs constructed as a result of this work provides validation of the initial hypothesis about DBM, and solar wind speed and also yields further insight into CME features like arrival time, arrival speed, lift-off time, etc. Using a data-driven approach, this procedure allows us to present a homogeneous, reliable, and robust dataset for the investigation of CME propagation. On the other hand, possible CME events are identified where DBM approximation is not valid due to model limitations and higher uncertainties in the input parameters, those events require more thorough investigation.

description: We present a versatile imaging scheme for fermionic $^6$Li atoms with single-particle sensitivity. Our method works for freely propagating particles and completely eliminates the need for confining potentials during the imaging process. We illuminate individual atoms in free space with resonant light and collect their fluorescence on an electron-multiplying CCD camera using a high-numerical-aperture imaging system. We detect approximately \num{20} photons per atom during an exposure of 20 $μ$s and identify individual atoms with a fidelity of $99.4\pm0.3$ % . By addressing different optical transitions during two exposures in rapid succession, we additionally resolve the hyperfine spin state of each particle. The position uncertainty of the imaging scheme is 4.0 $μ$m, given by the diffusive motion of the particles during the imaging pulse. The absence of confining potentials enables readout procedures, such as the measurement of single-particle momenta in time of flight, which we demonstrate here. Our imaging scheme is technically simple and easily adapted to other atomic species.

The N=4 string is the same as the N=2 string

description: We redo the quantization of the N=4 string, taking into account the reducibility of the constraints. The result is equivalent to the N=2 string, with critical dimension D=4 and signature (++--). The N=4 formulation has several advantages: the sigma-model field equations are implied classically, rather than by quantum/beta-function calculations; self-duality/chirality is one of the super-Virasoro constraints; SO(2,2) covariance is manifest. This reveals that the theory includes fermions, and is apparently spacetime supersymmetric.

description: Fast, accurate, and generalizable simulations are a key enabler of modern advances in robot design and control. However, existing simulation frameworks in robotics either model rigid environments and mechanisms only, or if they include flexible or soft structures, suffer significantly in one or more of these performance areas. To close this "sim2real" gap, we introduce DisMech, a simulation environment that models highly dynamic motions of rod-like soft continuum robots and structures, quickly and accurately, with arbitrary connections between them. Our methodology combines a fully implicit discrete differential geometry-based physics solver with fast and accurate contact handling, all in an intuitive software interface. Crucially, we propose a gradient descent approach to easily map the motions of hardware robot prototypes to control inputs in DisMech. We validate DisMech through several highly-nuanced soft robot simulations while demonstrating an order of magnitude speed increase over previous state of the art. Our real2sim validation shows high physical accuracy versus hardware, even with complicated soft actuation mechanisms such as shape memory alloy wires. With its low computational cost, physical accuracy, and ease of use, DisMech can accelerate translation of sim-based control for both soft robotics and deformable object manipulation.

description: In this letter, we generalize the convolutional NMF by taking the $β$-divergence as the contrast function and present the correct multiplicative updates for its factors in closed form. The new updates unify the $β$-NMF and the convolutional NMF. We state why almost all of the existing updates are inexact and approximative w.r.t. the convolutional data model. We show that our updates are stable and that their convergence performance is consistent across the most common values of $β$.
Imaging through a scattering medium by speckle intensity correlations

description: In this paper we analyze an imaging technique based on intensity speckle correlations over incident field position proposed in [J. A. Newmann and K. J. Webb, Phys. Rev. Lett. 113, 263903 (2014)]. Its purpose is to reconstruct a field incident on a strongly scattering random medium. The thickness of the complex medium is much larger than the scattering mean free path so that the wave emerging from the random section forms an incoherent speckle pattern. Our analysis clarifies the conditions under which the method can give a good reconstruction and characterizes its performance. The analysis is carried out in the white-noise paraxial regime, which is relevant for the applications in optics that motivated the original paper.

description: Combining experiments and ab initio models we report on $\rm SrPt_4Ge_{12}$ and $\rm BaPt_4Ge_{12}$ as members of a novel class of superconducting skutterudites, where Sr or Ba atoms stabilize a framework entirely formed by Ge-atoms. Below $T_c=5.35$ K, and 5.10 K for $\rm BaPt_4Ge_{12}$ and $\rm SrPt_4Ge_{12}$, respectively, electron-phonon coupled superconductivity emerges, ascribed to intrinsic features of the Pt-Ge framework, where Ge-$p$ states dominate the electronic structure at the Fermi energy.

description: Several works have recently suggested to model the problem of coordinating the charging needs of a fleet of electric vehicles as a game, and have proposed distributed algorithms to coordinate the vehicles towards a Nash equilibrium of such game. However, Nash equilibria have been shown to posses desirable system-level properties only in simplified cases. In this work, we use the concept of price of anarchy to analyze the inefficiency of Nash equilibria when compared to the social optimum solution. More precisely, we show that i) for linear price functions depending on all the charging instants, the price of anarchy converges to one as the population of vehicles grows; ii) for price functions that depend only on the instantaneous demand, the price of anarchy converges to one if the price function takes the form of a positive pure monomial; iii) for general classes of price functions, the asymptotic price of anarchy can be bounded. For finite populations, we additionaly provide a bound on the price of anarchy as a function of the number vehicles in the system. We support the theoretical findings by means of numerical simulations.

Femtosecond Photodissociation of Molecules Facilitated by Noise

description: We investigate the dynamics of diatomic molecules subjected to both a femtosecond mid-infrared laser pulse and Gaussian white noise. The stochastic Schrödinger equation with a Morse potential is used to describe the molecular vibrations under noise and the laser pulse. For weak laser intensity, well below the dissociation threshold, it is shown that one can find an optimum amount of noise that leads to a dramatic enhancement of the dissociation probability. The enhancement landscape which is shown as a function of both the noise and the laser strength, exhibits a global maximum. A frequency-resolved gain profile is recorded with a pump-probe set-up which is experimentally realizable. With this profile we identify the linear and nonlinear multiphoton processes created by the interplay between laser and noise and assess their relative contribution to the dissociation enhancement.

description: Copper transporter 1 (CTR1) is the main copper transporter in the eukaryotic system. CTR1 has several important roles: It binds Cu(II) ions that are present in the blood; it reduces those Cu(II) ions to Cu(I); and it subsequently transfers Cu(I) to the cytoplasmic domain, where the ion is delivered to various cellular pathways. Here, we seek to identify CTR1 binding sites for Cu(II) and Cu(I) and to shed light on the Cu(II)-to-Cu(I) reduction process. We focus on the first 14 amino acids of CTR1. This N-terminal segment is rich with histidine and methionine residues, which are known to bind Cu(II) and Cu(I), respectively; thus, this region has been suggested to have an important function in recruiting Cu(II) and reducing it to Cu(I). We utilize electron paramagnetic resonance (EPR) spectroscopy together with nuclear magnetic resonance (NMR) and UV-VIS spectroscopy and alanine substitution to reveal Cu(II) and Cu(I) binding sites in the focal 14-amino-acid segment. We show that H5 and H6 directly coordinate to Cu(II), whereas M7, M9, and M12 are involved in Cu(I) binding. This research is another step on the way to a complete understanding of the cellular copper regulation mechanism in humans.

description: We discuss the chemical evolution of metal poor galaxies and conclude that their oxygen deficiency is not due to: the production of black holes by massive stars or a varying slope of the Initial Mass Function, IMF, at the high-mass end. A varying IMF at the low-mass end alone or in combination with: (a) an outflow of oxygen-rich material, (b) an outflow of well-mixed material, and (c) the presence of dark matter that does not participate in the chemical evolution process, is needed to explain their oxygen deficiency. Outflow of material rich in oxygen helps to account for the large helium to oxygen mass ratio values derived from these objects, but it works against explaining the carbon to oxygen mass ratio and the heavy elements minus carbon and oxygen to oxygen mass ratio values.
