description: We present CHANDRA X-ray data of the nearby Magellanic Irregular dwarf starburst galaxy NGC4449. Contributions to the X-ray emission come from discrete point sources and extended diffuse emission. The extended emission has a complex morphology with an extent of 2.4x1.6kpc down to a flux density of 1.3E-13 erg/s/cm2/arcmin2. The best spectral fit to this emission is obtained with an absorbed, two temperature model giving temperatures for the two gas components of 0.28keV and 0.86keV, a total mass content of ~10^7 Msun compared with a galactic mass of several 10^{10} Msun and a total thermal energy content of ~2.5E55erg, with an average energy injection rate for the galaxy of a few 1E41 erg/s. Comparison of the morphology of the diffuse X-ray emission with that of the observed Halpha emission shows similarities in the two emissions. An expanding super-bubble is suggested by the presence of diffuse X-ray emission within what appears to be a cavity in the Halpha emission. The kinematics of this bubble suggest an expansion velocity of ~220km/s and a mass injection rate of 0.14Msun/yr, but the presence of NGC4449's huge HI halo (r~40kpc) may prevent the ejection, into the IGM, of the metal-enriched material and energy it contains. The arcsecond-resolution of CHANDRA has detected 24 X-ray point sources down to a completeness level corresponding to a flux of ~2E-14 erg/s/cm2, within the optical extent of NGC4449 and analysis of their spectra has shown them to be from at least 3 different classes of object. As well as the known SNR in this galaxy, it also harbours several X-ray binaries and super-soft sources. The point source X-ray luminosity function, for the higher luminosity sources, has a slope of ~-0.51, comparable to those of other starburst galaxies.

description: We elucidate the close connection between the repulsive lattice gas in equilibrium statistical mechanics and the Lovasz local lemma in probabilistic combinatorics. We show that the conclusion of the Lovasz local lemma holds for dependency graph G and probabilities {p_x} if and only if the independent-set polynomial for G is nonvanishing in the polydisc of radii {p_x}. Furthermore, we show that the usual proof of the Lovasz local lemma -- which provides a sufficient condition for this to occur -- corresponds to a simple inductive argument for the nonvanishing of the independent-set polynomial in a polydisc, which was discovered implicitly by Shearer and explicitly by Dobrushin. We also present some refinements and extensions of both arguments, including a generalization of the Lovasz local lemma that allows for "soft" dependencies. In addition, we prove some general properties of the partition function of a repulsive lattice gas, most of which are consequences of the alternating-sign property for the Mayer coefficients. We conclude with a brief discussion of the repulsive lattice gas on countably infinite graphs.

description: Realistic predictions for the arrival directions of ultra-high-energy cosmic rays require extensive simulations of UHECR propagation through 3D space, potentially even including cosmological evolution and timing effects. Such 3D or 4D simulations of cosmic-ray propagation suffer from the fact that a relatively small target - the observer sphere - needs to be hit. If particles are ejected in any direction from the source according to the source emission geometry, such simulations are tremendously inefficient. We present here a targeting mechanism which finds an optimal emission geometry to maximize the number of hits while remaining unbiased in the arrival-direction distribution. This can lead to speedups by many of orders of magnitude, depending on the simulation setup. We present the basic mathematics to produce unbiased results from targeted simulations, demonstrate its effectiveness with the simulation package CRPropa 3 for various propagation scenarios, and discuss prospects to include this mechanism as a standard part of CRPropa in the future.

Chinatown Park & A programmatic speculation for intergenerational gathering
Creators: name: Kuo, Marco
Publisher: name: The University of British Columbia
Year: 2024

description: Vancouver’s Chinatown as an enclave of resilience has a century-long history of being a neighbourhood for entrepreneurship, leadership and comfort. The struggle to survive and resist displacement and alienation is masked with an Asiatic decoration. Chinatown’s aesthetic has played two roles - a background for nostalgia, reminding inhabitants of an Asiatic past and an identifier for outsiders to imagine a foreign and curious land. With parkades being relatively large monoliths in Chinatown, they hold the interior space and are a familial infrastructure for existing Chinatown life. This thesis begins with the story of Chinese migration to Canada, specifically Vancouver, and proposes a programmatic speculation in Joe Wai’s Chinatown Parkade and Plaza.
Energy Crisis or a New Soliton in the Noncommutative CP(1) Model?
Creators: name: Ghosh, Subir
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The Non-Commutative (NC) CP(1) model is studied from field theory perspective. Our formalism and definition of the NC CP(1) model differs crucially from the existing one \cite{nccp}. Due to the U(1) gauge invariance, the Seiberg-Witten map is used to convert the NC action to an action in terms of ordinary spacetime degrees of freedom and the subsequent theory is studied. The NC effects appear as (NC parameter) $θ$-dependent interaction terms. The expressions for static energy, obtained from both the symmetric and canonical forms of the energy momentum tensor, are {\it {identical}}, when only spatial noncommutativity is present. Bogomolny analysis reveals a lower bound in the energy in an unambiguous way, suggesting the presence of a new soliton. However, the BPS equations saturating the bound are not compatible to the full variational equation of motion. This indicates that the definitions of the energy momentum tensor for this particular NC theory, (the NC theory is otherwise consistent and well defined), are inadequate, thus leading to the "energy crisis". A collective coordinate analysis corroborates the above observations. It also shows that the above mentioned mismatch between the BPS equations and the variational equation of motion is small.

 Type material. Holotype (male) and allotype (female): CHINA: Sichuan: “CHINA Sichuan SE of Lixian Danzhamu vall. Miyaluo Nat. Res. 3251 m 31.23.902"N 104.14.827E 18.6.2005 R. Sehnal & M. Tryzna (ASC).
 Diagnosis. Ocypus gorgias shares all character states with O. elpenor and differs from it mainly by the differently shaped aedoeagus and sternite 9 of the male genital segment.
 Description. In all character states quite similar to O. elpenor and different only by the differently shaped aedoeagus and sternite 9 of the male genital segment.
M a l e. Sternite 8 with medioapical emargination narrower. Genital segment with sternite 9 of similar shape, but with apex narrowly subtruncate, not emarginate (Fig. 151). Tergite 10 not appreciably different (Fig. 152). Aedoeagus large, shaped as in Figs. 153, 154; median lobe slightly asymmetrical, with narrowly arcuate apex; paramere markedly elongate, situated on median lobe slightly asymmetrically, with apical portion almost straight, narrowly arcuate apex not quite reaching apex of median lobe; sensory peg setae on underside of paramere forming two short lateral groups connected anteriorly; apical setae minute, situated as in Fig. 154.
 Female. Tergite 10 of genital segment similar to that of O. elpenor, but somewhat narrower with more acute apex (see Comments).
Length 16.0 mm.
 Bionomics. Nothing is known about collection circumstances of the two original specimens.
 Geographical distribution. Ocypus gorgias is at present known only from the type locality in Sichuan.
 Recognition and comments. Ocypus gorgias may be positively distinguished from O. elpenor only by the differently shaped aedoeagus (Figs. 136, 153) and sternite 9 of the male genital segment (Figs. 134, 151).
 The allotype is in fair shape, it is missing four outer segments of the left antenna, all but three basal segments of the right antenna, and the left hind tarsus. Due to the extended exposure to the fluids in pitfall traps, the setation of the sclerites of both the male and female genital segments is entirely missing. It is therefore impossible to establish, whether or not the peculiar setation of tergite 10 of the female genital segment of O. elpenor (Fig. 139) is present, or absent in O. gorgias.
 Etymology. The specific epithet is the name of Gorgias, - ae, m, the famous Greek sophist, a contemporary of Socrates, in apposition.

description: We propose a low-scale renormalizable trinification theory that successfully explains the flavor hierarchies and neutrino puzzle in the Standard Model (SM), as well as provides a dark matter candidate and also contains the necessary means for efficient leptogenesis. The proposed theory is based on the trinification $\SU{3}{C}\times \SU{3}{L}\times \SU{3}{R}$ gauge symmetry, which is supplemented with an additional flavor symmetry $\U{X}\times Z_{2}^{(1)} \times Z_{2}^{(2)}$. In the proposed model the top quark and the exotic fermions acquire tree-level masses, whereas the lighter SM charged fermions gain masses radiatively at one-loop level. In addition, the light active neutrino masses arise from a combination of radiative and type-I seesaw mechanisms, with the Dirac neutrino mass matrix generated at one-loop level.

description: Defects are common in software systems and can potentially cause various problems to software users, as software systems are getting larger and more complex, more defects can occur. Despite meticulous planning, well documentation and proper process control during software development, occurrences of a certain defects are inevitable. Many software development activities are performed by individuals, which may lead to different software defects over the development to occur, causing disappointments in the not-so distant future. Software defect prediction identifies the modules that are defect-prone and require extensive testing by capturing the syntax and different levels of semantics of source code. Software defect prediction plays an important role in improving software quality and it helps to reduce cost, time, and resources. Different methods have been developed to quickly predict the most likely locations of defects in large code bases. Most of them focus on designing features (e.g. complexity metrics) that correlate with potentially defective code. Those approaches however do not sufficiently capture the syntax and different levels of semantics of source code. However, to overcome this issue, a new technique has been introduced using source code to generate an abstract syntax tree to capture syntax and semantics. In addition to powerful deep learning techniques. This paper used recurrent neural networks and convolutional neural networks to achieve an accuracy of 78%, and 91% respectively.
Warped $AdS_{2}$ and $SU(1,1|4)$ symmetry in Type IIB

description: We investigate the existence of solutions with 16 supersymmetries to Type IIB supergravity on a spacetime of the form $AdS_{2}\times S^{5}\times S^{1}$ warped over a two-dimensional Riemann surface $Σ$. The existence of the Lie superalgebra $SU(1,1|4) \subset PSU(2,2|4)$, whose maximal bosonic subalgebra is $SO(2,1)\oplus SO(6)\oplus SO(2)$, motivates the search for half-BPS solutions with this isometry that are asymptotic to $AdS_{5} \times S^{5}$. We reduce the BPS equations to the Ansatz for the bosonic fields and supersymmetry generators compatible with these symmetries, then show that the only non-trivial solution is the maximally supersymmetric solution $AdS_{5}\times S^{5}$. We argue that this implies that no solutions exist for fully back-reacted D7 probe or D7/D3 intersecting branes whose near-horizon limit is of the form $AdS_{2}\times S^{5}\times S^{1}\times Σ$.

description: We consider the lattice version of the free field in two dimensions and study the fractal structure of the sets where the field is unusually high (or low). We then extend some of our computations to the case of the free field conditioned on being everywhere nonnegative. For example, we compute the width of the largest downward spike of a given length. Through the prism of these results, we find that the extrema of the free field under entropic repulsion (minus its mean) and those of the unconditioned free field are identical. Finally, when compared to previous results these findings reveal a suggestive analogy between the square of the free field and the two-dimensional simple random walk on the discrete torus.

description: Unconventional features of relativistic Dirac/Weyl quasi-particles in topological materials are most evidently manifested in the 2D quantum Hall effect (QHE), whose variety is further enriched by their spin and/or valley polarization. Although its extension to three dimensions has been long-sought and inspired theoretical proposals, material candidates have been lacking. Here we have discovered valley-contrasting spin-polarized Dirac fermions in a multilayer form in bulk antiferromagnet BaMnSb$_2$, where the out-of-plane Zeeman-type spin splitting is induced by the in-plane inversion symmetry breaking and spin-orbit coupling (SOC) in the distorted Sb square net. Furthermore, we have observed well-defined quantized Hall plateaus together with vanishing interlayer conductivity at low temperatures as a hallmark of the half-integer QHE in a bulk form. The Hall conductance of each layer is found to be nearly quantized to $2(N+1/2)e^2/h$ with $N$ being the Landau index, which is consistent with two spin-polarized Dirac valleys protected by the strong spin-valley coupling.

Isokrates as an observer and commentator upon his times

Subjects: subject: Isocrates Political and social views

description: This thesis sets out to provide the first major study in English of the historical significance of the six political discourses of Isokrates (Panegyrikos. Plataikos. Archidamos. On the Peace, Areopagitikos and Philippos). Each discourse is discussed individually, and each is closely examined with respect to its content and its historical context. For each, Isokrates' perspectives, ideas and judgements, whether idiosyncratic or compatible with other contemporary viewpoints, are assessed against available historical data, for both their historical plausibility and validity. Throughout the six chapters, which examine each of the political discourses in turn, it is argued that, despite the fact that these works are neither deliberate historical works nor genuine orations, designed for public delivery in the political contexts which constitute the settings, these discourses provide important historical evidence for the history of the times in which each was composed. Each work addresses at least one significant contemporary political issue; other related social, economic and military issues are also drawn into the discussion. Isokrates' own statements about the serious nature of his advice are shown to afford a more persuasive interpretation of these works than do attempts by some scholars to detach the composition of individual works from their proclaimed historical contexts or to show the works as principally rhetorical display-pieces. Isokrates eschewed a personal involvement in political life, either as rhetor or strategos. but his discourses reveal him as astute to contemporary issues of state and of inter-state relations. His commentary and advice upon current affairs was sometimes subtle, sometimes personal, but it cannot reasonably be portrayed as absurd, or even inept. Issues are not approached ideologically, but with a pragmatism not incompatible with a conservative and patriotic Athenian spirit. Isokrates cannot be characterized as a panhellenic visionary, pursuing persistently a singleminded policy: each discourse addresses its own peculiar situation, and, where apposite, policies are adapted to contemporary circumstances. Comparison with other evidence indicates that it is unlikely that Isokrates acted through these works as the mouthpiece of an active politician or of a political faction. Furthermore, his views and his advice, whether seen to be shared by others or whether perceived to be more idiosyncratic, can be perceived as a reasonable interpretation of the individual situations. Moreover, the advice appears to have been not entirely without influence, although two quite specific historical events have been mistakenly attributed to the direct influence of Isokrates' advice. In short, historians of Greek history of the Fourth century B. C. neglect these discourses at their peril.

Upward $μ^+ +μ^-$ event rates are estimated by taking into account total and nadir--angle dependent regeneration effects due to neutral current interactions. For exploring extragalactic neutrino sources at highest energies (\raisebox{-0.1cm}{$\stackrel{>}{\sim}$} $10^8$ GeV) with modern (future) ground--level telescopes, we analyze horizontal air shower event rates and shower events caused by Earth--skimming tau--neutrinos, in particular their detailed shower-- and cosmic neutrino--energy dependence. As an illustration of `new physics' implications we estimate the relevant horizontal air shower event rates due to spin--2 Kaluza--Klein `graviton' exchanges in neutral current neutrino--quark and neutrino--gluon interactions at low TeV--scales.

description: Providing high-quality, single-crystal diamond (SCD) with a large area is desirable for up-scaling quantum technology applications that rely on color centers in diamond. Growth methods aiming to increase the area of SCD are an active research area. Native color centers offer a sensitive probe for local crystal quality in such novel materials e.g., via their reaction to stress. In this work, we investigate individual native nitrogen-vacancy (NV) centers in SCD layers manufactured via laterally overgrowing hole arrays in a heteroepitaxially grown large-scale substrate. Heteroepitaxy has become a common tool for growing large SCDs; however, achieving the high crystal quality needed for quantum applications remains a challenge. In the overgrown layer, we identify NV centers with spin-decoherence times in the order of hundreds of microseconds, comparable to high-purity homoepitaxial SCD. We quantify the effective crystal strain in different regions of the overgrown layer, indicating a low stress overall and a stress reduction in the diamond layer above the holes.

description: A critical review is given of the current status of cosmological nucleosynthesis. In the framework of the standard model with 3 types of relativistic neutrinos, the baryon-to-photon ratio, η, corresponding to the inferred primordial abundances of helium-4 and lithium-7 is presently ~2 σbelow the value implied by the abundance of deuterium. The latter value is also coincident with the independent determination of ηfrom WMAP observations of CMB anisotropy. However taking systematic uncertainties in the abundance estimates into account, there is overall concordance in the range η= (3.4 - 6.9) x 10^{-10} @ 95% c.l. corresponding to a cosmological baryon density Ω_B h^2 = 0.012 - 0.025. If the above discrepancy is due to a neutrino chemical potential, then upto 7.1 effective neutrino species are allowed by nucleosynthesis. Other constraints on new physics are briefly discussed.

description: We study the worldvolume supersymmetries of M2 branes in the maximally supersymmetric plane wave background of M theory. For certain embeddings the standard probe analysis indicates that the worldvolume theory has less than 16 supersymmetries. We show that at the quadratic level the worldvolume theory admits additional linearly realized supersymmetries, and that the spectra of the branes are organized into multiplets of these symmetries. We find however that these supersymmetries are not respected by worldvolume interactions. Our analysis was motivated by recent work showing that D-branes in the maximally supersymmetric plane wave background of IIB string theory admit supersymmetries beyond those of the probe analysis. The construction of the additional supercharges in this case was specific to a string worldsheet that is a strip and the present results suggest that string interactions do not preserve these symmetries.

description: This paper proposes a multi-layer neural network structure for few-shot image recognition of novel categories. The proposed multi-layer neural network architecture encodes transferable knowledge extracted from a large annotated dataset of base categories. This architecture is then applied to novel categories containing only a few samples. The transfer of knowledge is carried out at the feature-extraction and the classification levels distributed across the two training stages. In the first-training stage, we introduce the relative feature to capture the structure of the data as well as obtain a low-dimensional discriminative space. Secondly, we account for the variable variance of different categories by using a network to predict the variance of each class. Classification is then performed by computing the Mahalanobis distance to the mean-class representation in contrast to previous approaches that used the Euclidean distance. In the second-training stage, a category-agnostic mapping is learned from the mean-sample representation to its corresponding class-prototype representation. This is because the mean-sample representation may not accurately represent the novel category prototype. Finally, we evaluate the proposed network structure on four standard few-shot image recognition datasets, where our proposed few-shot learning system produces competitive performance compared to previous work. We also extensively studied and analyzed the contribution of each component of our proposed framework.

description: Journal article published in Journal of Maps 2021 (http://dx.doi.org/10.1080/17445647.2021.1897047) Abstract: We present a method of digital geomorphological mapping of mountainous areas with a legend consisting of a three-tiered nested hierarchy using two case study areas from Vorarlberg, Austria. Users can easily visualize maps in a geographical information system (GIS) at the finest level with a legend of 33 morphogenetic domains. Reclassification of the morphogenetic classes in an automated GIS-workflow generates the medium and high levels of hierarchy, and each tier is accompanied bysuggested scale ranges for visualization. A variety of high-resolution input data (LiDAR-derived data, geomorphological and geological raster maps) supports the mapping method, which also strongly benefits from field knowledge. The method facilitates analysis, interpretation, visualization and application of geomorphological data at a large range of scales and corresponding information densities within one database. The structure of the legend allows for inclusion of additional morphogenetic classes and for application and adaptation in other environments.
The cold circumgalactic environment of MAMMOTH-I: dynamically cold gas in the core of an Enormous Ly-alpha Nebula

description: The MAMMOTH-I Nebula at redshift 2.3 is one of the largest known Ly-alpha nebulae in the Universe, spanning ~440 kpc. Enormous Ly-alpha nebulae like MAMMOTH-I typically trace the densest and most active regions of galaxy formation. Using sensitive low-surface-brightness observations of CO(1-0) with the Very Large Array, we trace the cold molecular gas in the inner 150 kpc of the MAMMOTH-I Nebula. CO is found in four regions that are associated with either galaxies or groups of galaxies that lie inside the nebula. In three of the regions, the CO stretches up to ~30 kpc into the circum-galactic medium (CGM). In the centermost region, the CO has a very low velocity dispersion (FWHM$_{\rm CO}$ ~ 85 km/s), indicating that this gas is dynamically cold. This dynamically cold gas coincides with diffuse restframe optical light in the CGM around a central group of galaxies, as discovered with the Hubble Space Telescope. We argue that this likely represents cooling of settled and enriched gas in the center of MAMMOTH-I. This implies that the dynamically cold gas in the CGM, rather than the obscured AGN, marks the core of the potential well of this Ly-alpha nebula. In total, the CO in the MAMMOTH-I Nebula traces a molecular gas mass of M$_{\rm H2}$ ~ 1.4 ($α_{\rm CO}$/3.6) $\times$ 10$^{11}$ M$_{\odot}$, with roughly 50% of the CO(1-0) emission found in the CGM. Our results add to the increasing evidence that extended reservoirs of molecular gas exist in the CGM of massive high-z galaxies and proto-clusters.

description: We proposed two different methods for simulating theta-vacuum systems. Both can be affected by systematic effects but these errors can be controlled by comparing the results of the two unrelated methods. This has been done for some analytically soluble models and here the same procedure is successfully applied to the interesting case of CP^9 in the scaling region.

description: Given multi-type point maps from different place-types (e.g., tumor regions), our objective is to develop a classifier trained on the source place-type to accurately distinguish between two classes of the target place-type based on their point arrangements. This problem is societally important for many applications, such as generating clinical hypotheses for designing new immunotherapies for cancer treatment. The challenge lies in the spatial variability, the inherent heterogeneity and variation observed in spatial properties or arrangements across different locations (i.e., place-types). Previous techniques focus on self-supervised tasks to learn domain-invariant features and mitigate domain differences; however, they often neglect the underlying spatial arrangements among data points, leading to significant discrepancies across different place-types. We explore a novel multi-task self-learning framework that targets spatial arrangements, such as spatial mix-up masking and spatial contrastive predictive coding, for spatially-delineated domain-adapted AI classification. Experimental results on real-world datasets (e.g., oncology data) show that the proposed framework provides higher prediction accuracy than baseline methods.

description: The great plains region is one of the most extensively altered ecosystems on earth, with less than 1% of its 2 million acres not being used for agricultural development. Landscapes have been divided, sold, machined, and squeezed of resources over the last century and a half. These actions constructed new landscapes, hostile and void of native flora and fauna, with the ruins of failed ventures telling a stunted story of the landscape. People are left unfamiliar and incurious about the natural prairie landscape. This project proposes an intervention within a 1.6km square plot of abandoned agricultural land, including the ruins of a ghost town, to invite the occasional visitor to experience and imagine the stories of the site, beyond what we see on the surface. The site, as well as others like it, will not return to what it looked like before human disturbance, the landscape moving forward reflects the life cycle of the natural landscape and past interventions, with lessons to be learnt.

At low ionic strength and low surface charge density in which a single polyelectrolyte is able to be adsorbed onto the surface, different regimes in the phase diagram are identified. The possibility of multi-layer structure formed by polyelectrolytes of like charge is also investigated.
