description: Most person re-identification (ReID) approaches assume that person images are captured under relatively similar illumination conditions. In reality, long-term person retrieval is common, and person images are often captured under different illumination conditions at different times across a day. In this situation, the performances of existing ReID models often degrade dramatically. This paper addresses the ReID problem with illumination variations and names it as {\em Illumination-Adaptive Person Re-identification (IA-ReID)}. We propose an Illumination-Identity Disentanglement (IID) network to dispel different scales of illuminations away while preserving individuals' identity information. To demonstrate the illumination issue and to evaluate our model, we construct two large-scale simulated datasets with a wide range of illumination variations. Experimental results on the simulated datasets and real-world images demonstrate the effectiveness of the proposed framework.

description: We define a two-sided analog of Erdös measure on the space of two-sided expansions with respect to the powers of the golden ratio, or, equivalently, the Erdös measure on the 2-torus. We construct the transformation (goldenshift) preserving both Erdös and Lebesgue measures on $\Bbb T^2$ which is the induced automorphism with respect to the ordinary shift (or the corresponding Fibonacci toral automorphism) and proves to be Bernoulli with respect to both measures in question. This provides a direct way to obtain formulas for the entropy dimension of the Erdös measure on the interval, its entropy in the sense of Garsia-Alexander-Zagier and some other results. Besides, we study central measures on the Fibonacci graph, the dynamics of expansions and related questions.

description: Raman spectroscopic observations of the characteristics and dissociation of methane hydrate were carried out on hydrates synthesized in silica sands with particle sizes of 53-75 μm, 90-106 μm, 106-150 μm, and 150-180 μm. The results obtained indicate that methane hydrates formed in silica sands had similar characteristics regarding cage occupancy and hydration number (5.99) to bulk hydrate, indicative of no influence of particle size on hydrate composition. During hydrate dissociation, the change in average intensity ratio of large to small cages were generally consistent with that of bulk hydrate but dropped dramatically after a certain time, and this turning point seems to be related to the particle size of silica sands.

description: We theoretically study Rashba-Edelstein magnetoresistance (REMR) in a two-dimensional electron gas (2DEG) system with Rashba and Dresselhaus spin-orbit interactions. We consider a microscopic model of a junction system composed of a ferromagnetic insulator and a 2DEG, and derive analytic expressions for the spin and current densities in the 2DEG using the Boltzmann equation, while taking into account dynamical contributions from magnons. Our findings reveal that the sign of the REMR varies depending on the type of interface. We also discuss the experimental relevance of our results.

description: The breakup pathway of Rayleigh fission of a charged drop is unequivocally demonstrated by first of its kind, continuous, high-speed imaging of a drop levitated in an AC quadrupole trap. The experimental observations consistently exhibited asymmetric, sub-critical Rayleigh breakup with an upward (i.e. opposite to the direction of gravity) ejection of a jet from the levitated drop. These experiments supported by numerical calculations show that the gravity induced downward shift of the equilibrium position of the drop in the trap cause significant, large amplitude shape oscillations superimposed over the center-of-mass oscillations. The shape oscillations result in sufficient deformations to act as triggers for the onset of instability well below the Rayleigh limit (a subcritical instability). At the same time, the center-of-mass oscillations which are out of phase with the applied voltage, lead to an asymmetric breakup such that the Rayleigh fission occurs upwards via the ejection of a jet at the pole of the deformed drop. As an important application, it follows from corollarial reasoning that the nanodrop generation in electrospray devices will occur, more as a rule rather than as an exception, via asymmetric, subcritical Rayleigh fission events of micro drops due to inherent directionality provided by the external electric fields.

description: Visible light communication (VLC) complements radio frequency in indoor environments with large wireless data traffic. However, VLC is hindered by dramatic path losses when an opaque object is interposed between the transmitter and the receiver. Prior works propose the use of plane mirrors as optical reconfigurable intelligent surfaces (ORISs) to enhance communications through non-line-of-sight links. Plane mirrors rely on their orientation to forward the light to the target user location, which is challenging to implement in practice. This paper studies the potential of curved mirrors as static reflective surfaces to provide a broadening specular reflection that increases the signal coverage in mirror-assisted VLC scenarios. We study the behavior of paraboloid and semi-spherical mirrors and derive the irradiance equations. We provide extensive numerical and analytical results and show that curved mirrors, when developed with proper dimensions, may reduce the shadowing probability to zero, while static plane mirrors of the same size have shadowing probabilities larger than 65%. Furthermore, the signal-to-noise ratio offered by curved mirrors may suffice to provide connectivity to users deployed in the room even when a line-of-sight link blockage occurs.

Magnification effects as measures of large-scale structure
Creators: name: Jain, Bhuvnesh
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The magnification effects of clustered matter produce variations in the image sizes and number density of galaxies across the sky. This paper advocates the use of these effects in wide field surveys to map large-scale structure and the profiles of galaxy and cluster sized halos. The magnitude of the size variation as a function of angular scale is computed and the signal-to-noise is estimated for different survey parameters. Forthcoming surveys, especially well designed space-based imaging surveys, will have high signal-to-noise on scales of about 0.1 arcminute to several degrees. Thus the clustering of matter could be measured on spatial scales of about 50 Kpc to 100 Mpc. The signal-to-noise is dominated by sample variance rather than shot-noise due to the finite number density of galaxies, hence the accuracy of the measurements will be limited primarily by survey area, sampling strategy and possible systematics. Methods based on magnification are compared with the use of shape distortions and the contrasts and complementarities are discussed. Future work needed to plan survey strategy and interpret measurements based on magnification is outlined.

description: This work uses hierarchical logistic Gaussian processes to infer true redshift distributions of samples of galaxies, through their cross-correlations with spatially overlapping spectroscopic samples. We demonstrate that this method can accurately estimate these redshift distributions in a fully Bayesian manner jointly with galaxy-dark matter bias models. We forecast how systematic biases in the redshift-dependent galaxy-dark matter bias model affect redshift inference. Using published galaxy-dark matter bias measurements from the Illustris simulation, we compare these systematic biases with the statistical error budget from a forecasted weak gravitational lensing measurement. If the redshift-dependent galaxy-dark matter bias model is mis-specified, redshift inference can be biased. This can propagate into relative biases in the weak lensing convergence power spectrum on the 10% - 30% level. We, therefore, showcase a methodology to detect these sources of error using Bayesian model selection techniques. Furthermore, we discuss the improvements that can be gained from incorporating prior information from Bayesian template fitting into the model, both in redshift prediction accuracy and in the detection of systematic modeling biases.

description: We report the discovery of Ge III $λ$1088.46 in the planetary nebulae (PNe) SwSt 1, BD+30$^{\rm o}$3639, NGC 3132, and IC 4593, observed with the Far Ultraviolet Spectroscopic Explorer. This is the first astronomical detection of this line and the first measurement of Ge (Z = 32) in PNe. We estimate Ge abundances using S and Fe as reference elements, for a range of assumptions about gas-phase depletions. The results indicate that Ge, which is synthesized in the initial steps of the s-process and therefore can be self-enriched in PNe, is enhanced by factors of > 3-10. The strongest evidence for enrichment is seen for PNe with Wolf-Rayet central stars, which are likely to contain heavily processed material.

Holomorphic automorphic forms have the property that they analytically extend to holomorphic functions on a complex Ol'shanski\uı semigroup $S\subeq G_\C$. As an application we prove that the bounded holomorphic functions on $Γ\bs S\subseteq Γ\bs G_\C$ separate the points.

description: This work is a continuation of our previous paper arXiv:1812.06473 where we have constructed ${\cal N}=2$ supersymmetric Yang-Mills theory on 4D manifolds with a Killing vector field with isolated fixed points. In this work we expand on the mathematical aspects of the theory, with a particular focus on its nature as a cohomological field theory. The well-known Donaldson-Witten theory is a twisted version of ${\cal N}=2$ SYM and can also be constructed using the Atiyah-Jeffrey construction. This theory is concerned with the moduli space of anti-self-dual gauge connections, with a deformation theory controlled by an elliptic complex. More generally, supersymmetry requires considering configurations that look like either instantons or anti-instantons around fixed points, which we call flipping instantons. The flipping instantons of our 4D ${\cal N}=2$ theory are derived from the 5D contact instantons. The novelty is that their deformation theory is controlled by a transversally elliptic complex, which we demonstrate here. We repeat the Atiyah-Jeffrey construction in the equivariant setting and arrive at the Lagrangian (an equivariant Euler class in the relevant field space) that was also obtained from our previous work arXiv:1812.06473. We show that the transversal ellipticity of the deformation complex is crucial for the non-degeneracy of the Lagrangian and the calculability of the theory. Our construction is valid on a large class of quasi toric 4 manifolds.

description: This paper presents a geometric-variational approach to continuous and discrete mechanics and field theories. Using multisymplectic geometry, we show that the existence of the fundamental geometric structures as well as their preservation along solutions can be obtained directly from the variational principle. In particular, we prove that a unique multisymplectic structure is obtained by taking the derivative of an action function, and use this structure to prove covariant generalizations of conservation of symplecticity and Noether's theorem. Natural discretization schemes for PDEs, which have these important preservation properties, then follow by choosing a discrete action functional. In the case of mechanics, we recover the variational symplectic integrators of Veselov type, while for PDEs we obtain covariant spacetime integrators which conserve the corresponding discrete multisymplectic form as well as the discrete momentum mappings corresponding to symmetries. We show that the usual notion of symplecticity along an infinite-dimensional space of fields can be naturally obtained by making a spacetime split. All of the aspects of our method are demonstrated with a nonlinear sine-Gordon equation, including computational results and a comparison with other discretization schemes.

Constraining the Equation of State of Neutron Stars through GRB X-Ray Plateaus

description: The unknown equation of state (EoS) of neutron stars (NSs) is puzzling because of rich non-perturbative effects of strong interaction there. A method to constrain the EoS by using the detected X-ray plateaus of gamma-ray bursts (GRBs) is proposed in this paper. Observations show some GRB X-ray plateaus may be powered by strongly magnetized millisecond NSs. The properties of these NSs should then satisfy: (i) the spin-down luminosity of these NSs should be brighter than the observed luminosity of the X-ray plateaus; (ii) the total rotational energy of these NSs should be larger than the total energy of the X-ray plateaus. Through the case study of GRB 170714A, the moment of inertia of NSs is constrained as $I>1.0\times 10^{45}\left ( \frac{P_{\rm cri}}{1\;\rm ms} \right )^{2} \;\rm g\cdot cm^{2}$, where $P_{\rm cri}$ is the critical rotational period that an NS can achieve. The constraint of the radii of NSs according to GRB 080607 is shown in Table 1.

description: The purpose of this study was to determine whether teaching students about the structure of a text would be associated with improved reading comprehension. Science texts were used with the intention of adding to what is known about content-area reading comprehension. To investigate the effects of teaching science text structure, a reading comprehension program called Comprehending Science Texts with Structure (CSTS) was developed and tested using an true experimental design. Importantly, the study was conducted in China with Mandarin-speaking students, with whom there has been a great shortage of reading research. The CSTS program is a 15-lesson reading comprehension program designed to teach middle school students how to comprehend science texts by using three text structure strategies, namely asking generic questions (GQs), using graphic organizers (GOs), and summary writing (SW). A total of 88 sixth grade students participated in this study and were randomly assigned to either the CSTS intervention group or the content-only control group. After the completion of the CSTS program, students’ text structure knowledge and reading comprehension were measured using researcher-designed measures of the comprehension of both science and generic text. The generic text was used in order to investigate near-transfer effects. Far transfer was measured post-intervention through the use of two standardized reading tests, one taken from a state assessment and the other from the PISA reading test. Results from multivariate analyses of covariance indicated that, overall, students in the treatment group significantly outperformed their counterparts in the control group after controlling for pretest reading skill and science knowledge. Specifically, students who received the CSTS intervention showed significant acquisition of science texts structure knowledge and also significantly outperformed the controls in the comprehension of science texts. The results also demonstrated the near-transfer effects of the CSTS from science texts to generic texts; here, students in the treatment group significantly gained generic text structure knowledge and also significantly outperformed the controls in the comprehension of generic texts significant. A far-transfer effect, however, was not found, as the two groups did not show a statistically significant difference in performance on the post-test standardized reading comprehension tests.

description: For every finite graph $Γ$, we define a simplicial complex associated to the outer automorphism group of the RAAG $A_Γ$. These complexes are defined as coset complexes of parabolic subgroups of $Out^0(A_Γ)$ and interpolate between Tits buildings and free factor complexes. We show that each of these complexes is homotopy Cohen-Macaulay and in particular homotopy equivalent to a wedge of d-spheres. The dimension d can be read off from the defining graph $Γ$ and is determined by the rank of a certain Coxeter subgroup of $Out^0(A_Γ)$. In order to show this, we refine the decomposition sequence for $Out^0(A_Γ)$ established by Day-Wade, generalise a result of Brown concerning the behaviour of coset posets under short exact sequences and determine the homotopy type of free factor complexes associated to relative automorphism groups of free products.

description: In two experiments, I tested the effects of a curriculum-based intervention on preschool students’ degree of stimulus control for bidirectional naming (BiN) across familiar and unfamiliar word-picture relation levels of complexity. In Experiment I, I used a multiple probe design to test the effects of the curriculum-based intervention on the degree of BiN for familiar word-picture relations. All four participants in the first experiment demonstrated an increase in the degree of BiN for familiar picture-word relation, with three participants meeting the incidental BiN criterion level of 80% across three response topographies. In Experiment II, I compared the curriculum-based intervention and repeated novel naming experience (RNNE) on preschool students’ degree of BiN and learning. The dependent variables were 1) degree of stimulus control for BiN across familiar and unfamiliar word-picture relations 2) learn units to criterion across math and reading 3) percentage of correct responses to unconsequated post-math and reading instruction probes. I investigated whether the method of acquisition of BiN, a curriculum based or RNNE, has differential effects on the dependent variables. Three out of four participants who received the curriculum-based intervention acquired BiN for picture-word relations following a novel experience, while one out of four participants under the RNNE condition acquired BiN. The results of the study suggest that a curriculum-based instruction can simultaneously induce BiN while teaching academic objectives to preschool students. Experiment II also implicates the effects of a technology-mediated intervention on developing academic and verbal behavior development cusps even in young children.

Accretion of low angular momentum material onto black holes: 2D hydrodynamical inviscid case

Publisher: name: arXiv
Year: 2002

description: We report on the first phase of our study of slightly rotating accretion flows onto black holes. We consider inviscid accretion flows with a spherically symmetric density distribution at the outer boundary, but with spherical symmetry broken by the introduction of a small, latitude-dependent angular momentum. We study accretion flows by means of numerical 2D, axisymmetric, hydrodynamical simulations. Our main result is that the properties of the accretion flow do not depend as much on the outer boundary conditions (i.e., the amount as well as distribution of the angular momentum) as on the geometry of the non-accreting matter. The material that has too much angular momentum to be accreted forms a thick torus near the equator. Consequently, the geometry of the polar region, where material is accreted (the funnel), and the mass accretion rate through it are constrained by the size and shape of the torus. Our results show one way in which the mass accretion rate of slightly rotating gas can be significantly reduced compared to the accretion of non-rotating gas (i.e., the Bondi rate), and set the stage for calculations that will take into account the transport of angular momentum and energy.

description: Η ανάπτυξη των νέων τεχνολογιών που έχουν προκύψει από τα μέσα της δεκαετίας του 1990 οδήγησε σε εφαρμογές βασισμένες στο διαδίκτυο γνωστές ως «κοινωνικά μέσα» που επιτρέπουν στους ανθρώπους να αλληλεπιδρούν και να έχουν πρόσβαση σε πληροφορίες. Στην παρούσα εργασία εξετάζεται πως οι οργανισμοί έκτακτης ανάγκης χρησιμοποιούν τις διαθέσιμες τεχνολογίες των κοινωνικών μέσων για την αντιμετώπιση μιας κρίσης. Σκοπός της παρούσης εργασίας είναι να διερευνηθεί αν τα κοινωνικά μέσα μπορούν να χρησιμοποιηθούν και να γίνουν αποδεκτά ως πιθανά εργαλεία που επιτρέπουν σε άτομα και οργανώσεις να συνεργαστούν με αμοιβαία επωφελείς τρόπους, σε όλα τα στάδια της διαχείρισης καταστάσεων έκτακτης ανάγκης: μετριασμός, ετοιμότητα, αντιμετώπιση.
 Η έρευνα βασίζεται σε βιβλιογραφική επισκόπηση και εμπειρική μελέτη περιπτώσεων στα πλέον γνωστά κοινωνικά δίκτυα όπως το Facebook, twitter, youtube κ.τ.λ.
 Οι συνδεμένοι ιστότοποι κοινωνικής δικτύωσης γίνονται εξαιρετικά δημοφιλείς και μπορούν να χρησιμοποιηθούν σε μια ποικιλία από περιβάλλοντα και κατά πολλούς ερευνητές μπορούν σε καταστάσεις έκτακτης ανάγκης να προφέρουν μια λύση ως “on – stop shop”.
 Τα αποτελέσματα αυτής της αναγνωριστικής έρευνας δείχνουν ότι οι συνδεμένοι ιστότοποι κοινωνικής δικτύωσης θα πρέπει να θεωρούνται βιώσιμη λύση στα προβλήματα που μαστίζουν τη διάδοση των πληροφοριών και των επικοινωνιών στον τομέα έκτακτης ανάγκης. Ερευνητικά θέματα προκύπτουν στους τομείς της πρόσβασης στα δεδομένα, την ποιότητα των δεδομένων, τη σύνθεση των πληροφοριών, αναδυόμενα πρότυπα της ανθρώπινης συμπεριφοράς σε καταστάσεις έκτακτης ανάγκης, προστασία της ιδιωτικής ζωής κτλ.

Effects of War After War: A Quantitative Comparison of the Economic Performance of Jewish World War II Veterans to Non-Jewish World War II Veterans
Creators: Shields, Michael
Publisher: name: Columbia University
Year: 2013
Subjects: subject: Sociology
subject: FOS: Sociology

description: There is relatively little comparative research studying religious subgroups of military veterans. Using data from the 1970 United States Census, the income and the influences on the income of Jewish World War II veterans were compared to the income and the influences on the income of non-Jewish World War II veterans. The same analyses were then performed on veterans of the Korean War and the Vietnam War and compared to World War II veterans. Additionally, a novel approach was used to quantify the association of military service during World War II with the income of veterans. Jewish World War II veterans and Jewish Korean War veterans earn a greater amount of income than non-Jewish World War II veterans and non-Jewish Korean War veterans. Military service during World War II is associated with a decrease in the income of Jews and an increase in the income of non-Jews. The influences on income differ by religion, war, and veteran status. The results are discussed within a framework of sociological theory. This paper was submitted in partial fulfillment of the requirements for the degree of Master of Arts in Quantitative Methods in the Social Sciences.
CLATHRATES OF HYDROGEN WITH APPLICATION TOWARDS HYDROGEN STORAGE

description: In the current work we present a significant advancement in the area of hydrogen storage in clathrates: hydrogen storage from both enclathrated molecular hydrogen as well as storage from the clathrate host lattice. We have investigated the hydrogen storage potential in all of the common clathrate hydrate structures with techniques such as gas evolution, X-ray / neutron diffraction, and NMR / Raman spectroscopy. We have determined that the common clathrate structures may not suffice as H2 storage materials, although these findings will aid in the design and production of enhanced hydrogen storage materials and in the understanding of structure-stability relations of guest-host systems. In view of current storage limitations, we propose a novel chemical – clathrate hybrid hydrogen storage concept that holds great promise for future materials.

description: The discovery of two-dimensional transition metal dichalcogenides (2D TMDs) has promised next-generation photonics and optoelectronics applications, particularly in the realm of nanophotonics. Arguably, the most crucial fundamental processes in these applications are the exciton migration and charge transfer in 2D TMDs. However, exciton dynamics in 2D TMDs have never been studied on a nanophotonic platform and more importantly, the control of exciton dynamics by means of nanophotonic structures has yet to be explored. Here, for the first time, we demonstrate the control of exciton dynamics in MoS2 monolayers by introducing a hyperbolic metamaterial (HMM) substrate. We reveal the migration mechanisms of various excitons in MoS2 monolayers. Furthermore, we demonstrate the Förster radius of the A-excitons can be increased by introducing HMMs through the nonlocal effects of HMMs due to the Purcell effect. On the other hand, the diffusion coefficient is unchanged for the C-excitons on HMMs. This study provides a revolutionary step forward in enabling 2D TMD nanophotonics hybrid devices.

Gauge theory and the division algebras

description: We present a novel formulation of the instanton equations in 8-dimensional Yang-Mills theory. This formulation reveals these equations as the last member of a series of gauge-theoretical equations associated with the real division algebras, including flatness in dimension 2 and (anti-)self-duality in 4. Using this formulation we prove that (in flat space) these equations can be understood in terms of moment maps on the space of connections and the moduli space of solutions is obtained via a generalised symplectic quotient: a Kaehler quotient in dimension 2, a hyperkaehler quotient in dimension 4 and an octonionic Kaehler quotient in dimension 8. One can extend these equations to curved space: whereas the 2-dimensional equations make sense on any surface, and the 4-dimensional equations make sense on an arbitrary oriented manifold, the 8-dimensional equations only make sense for manifolds whose holonomy is contained in Spin(7). The interpretation of the equations in terms of moment maps further constraints the manifolds: the surface must be orientable, the 4-manifold must be hyperkaehler and the 8-manifold must be flat.

Contextual advantage for state-dependent cloning

description: A number of noncontextual models exist which reproduce different subsets of quantum theory and admit a no-cloning theorem. Therefore, if one chooses noncontextuality as one's notion of classicality, no-cloning cannot be regarded as a nonclassical phenomenon. In this work, however, we show that there are aspects of the phenomenology of quantum state cloning which are indeed nonclassical according to this principle. Specifically, we focus on the task of state-dependent cloning and prove that the optimal cloning fidelity predicted by quantum theory cannot be explained by any noncontextual model. We derive a noise-robust noncontextuality inequality whose violation by quantum theory not only implies a quantum advantage for the task of state-dependent cloning relative to noncontextual models, but also provides an experimental witness of noncontextuality.

description: We review and summarize recent works on the relation between form factors in integrable quantum field theory and deformation of geometrical data associated to hyper-elliptic curves. This relation, which is based on a deformation of the Riemann bilinear identity, in particular leads to the notion of null vectors in integrable field theory and to a new description of the KdV hierarchy.
