description: In this letter, we propose a magnet-less non-reciprocal isolating system based on time-varying metasurfaces. Two parallel time-varying metasurfaces, one for frequency up-conversion and one for down-conversion by the same amount, are used for realizing a region of space where incident waves from opposite directions experience an opposite Doppler frequency shift. As a result, any device within this region becomes sensitive to the illumination direction, exhibiting a different scattering response from opposite directions and thus breaking reciprocity. Very importantly, thanks to the opposite frequency shift of the metasurfaces, the frequency of the transmitted electromagnetic field is the same as for the incident one. Here, we demonstrate this general approach by using a Bragg grating as the device between the time-varying metasurfaces. The combined structure of the metasurfaces and the grating exhibits different transmission and reflection properties for opposite illumination direction, thereby realizing an isolator. More broadly, this letter presents a strategy for converting any conventional electromagnetic device to a non-reciprocal one by placing it between two time-varying metasurfaces. This approach opens the door to several new non-reciprocal components based on thin and lightweight metasurfaces, which are simpler to realize compared to their volumetric counterparts.
General $SU(2)_L\times SU(2)_R \times U(1)_{EM}$ Sigma Model With External Sources, Dynamical Breaking And Spontaneous Vacuum Symmetry Breaking

description: We give a general $SU(2)_L\times SU(2)_R$ $\times U(1)_{EM}$ sigma model with external sources, dynamical breaking and spontaneous vacuum symmetry breaking, and present the general formulation of the model. It is found that $σ$ and $π^0$ without electric charges have electromagnetic interaction effects coming from their internal structure. A general Lorentz transformation relative to external sources $J_{gauge}$ $=(J_{A_μ},J_{A_μ^κ})$ is derived, using the general Lorentz transformation and the four-dimensional current of nuclear matter of the ground state with $J_{gauge}$ = 0, we give the four-dimensional general relations between the different currents of nuclear matter systems with $J_{gauge}\neq 0$ and those with $J_{gauge}=0$. The relation of the density's coupling with external magnetic field is derived, which conforms well to dense nuclear matter in a strong magnetic field. We show different condensed effects in strong interaction about fermions and antifermions, and give the concrete scalar and pseudoscalar condensed expressions of $σ_0$ and $π_0$ bosons. About different dynamical breaking and spontaneous vacuum symmetry breaking, the concrete expressions of different mass spectra are obtained in field theory. This paper acquires the running spontaneous vacuum breaking value $σ_0^{\prime},$ and obtains the spontaneous vacuum breaking in terms of the running $σ_0^{\prime}$, which make nucleon, $σ$ and $π$ particles gain effective masses. We achieve both the effect of external sources and nonvanishing value of the condensed scalar and pseudoscalar paticles. It is deduced that the masses of nucleons, $σ$ and $π$ generally depend on different external sources.

Can Plant Functional Traits Be Used as Integrators of Environmental Stressors in Urban Areas?
Creators: name: Dziedzic, Nicole
Publisher: name: University of Illinois at Chicago
Year: 2024

description: This study investigates the environmental differences and tree leaf structure and morphology in urban and suburban sites in the Chicago Metropolitan region. The leaf functional traits of Norway Maple and Littleleaved Linden were studied in three locations in the summer of 2023: an urban park (University of Illinois Chicago, Chicago, IL), a suburban park (Morton Arboretum in Lisle, IL), and a suburban residential site (Lombard, IL). Our urban site had higher daytime and nighttime air and land surface temperatures compared to suburban sites, with significant fluctuations observed across the sites. Cumulative growing degree days, a measure of potential photosynthetic active days, were higher in the urban site than in the suburban sites during March and August. Norway Maple trees growing in the urban site had higher specific leaf area (SLA) and lower leaf dry matter content (LDMC) than in suburban sites, resulting in bigger and thinner leaves than in suburban sites. Similarly, Little−leaved Linden trees in suburban residential sites displayed higher SLA and lower LDMC than trees of the same species in suburban park and residential sites. Gas exchange traits, namely photosynthetic assimilation, transpiration rates, and stomatal conductance, decreased between the urban and two suburban sites as temperatures increased throughout the summer. The influence of species and site on gas exchange traits was significant during the summer but not during the fall. Norway Maple gas exchange values decreased as the growing season progressed, as expected by ontogeny. In contrast, Little−leaved Linden maintained similar leaf gas exchange values throughout the growing season. Comparisons with existing global trait databases emphasize the need for localized data to capture site−specific responses accurately because although some traits aligned well with database values, others deviated significantly, underscoring the importance of comprehensive datasets for robust ecosystem modeling and management strategies.
On the cyclic subgroup separability of free products of two groups with amalgamated subgroup

description: Let $G$ be a free product of two groups with amalgamated subgroup, $π$ be either the set of all prime numbers or the one-element set \{$p$\} for some prime number $p$. Denote by $Σ$ the family of all cyclic subgroups of group $G$, which are separable in the class of all finite $π$-groups. Obviously, cyclic subgroups of the free factors, which aren't separable in these factors by the family of all normal subgroups of finite $π$-index of group $G$, the subgroups conjugated with them and all subgroups, which aren't $π^{\prime}$-isolated, don't belong to $Σ$. Some sufficient conditions are obtained for $Σ$ to coincide with the family of all other $π^{\prime}$-isolated cyclic subgroups of group $G$. It is proved, in particular, that the residual $p$-finiteness of a free product with cyclic amalgamation implies the $p$-separability of all $p^{\prime}$-isolated cyclic subgroups if the free factors are free or finitely generated residually $p$-finite nilpotent groups.

description: With increasingly large data sets, weak lensing measurements are able to measure cosmological parameters with ever greater precision. However this increased accuracy also places greater demands on the statistical tools used to extract the available information. To date, the majority of lensing analyses use the two point-statistics of the cosmic shear field. These can either be studied directly using the two-point correlation function, or in Fourier space, using the power spectrum. But analyzing weak lensing data inevitably involves the masking out of regions or example to remove bright stars from the field. Masking out the stars is common practice but the gaps in the data need proper handling. In this paper, we show how an inpainting technique allows us to properly fill in these gaps with only $N \log N$ operations, leading to a new image from which we can compute straight forwardly and with a very good accuracy both the pow er spectrum and the bispectrum. We propose then a new method to compute the bispectrum with a polar FFT algorithm, which has the main advantage of avoiding any interpolation in the Fourier domain. Finally we propose a new method for dark matter mass map reconstruction from shear observations which integrates this new inpainting concept. A range of examples based on 3D N-body simulations illustrates the results.

Associated Charm Production in Neutrino-Nucleus Interactions

Year: 2007
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: In this paper a search for associated charm production both in neutral and charged current $ν$-nucleus interactions is presented. The improvement of automatic scanning systems in the {CHORUS} experiment allows an efficient search to be performed in emulsion for short-lived particles. Hence a search for rare processes, like the associated charm production, becomes possible through the observation of the double charm-decay topology with a very low background. About 130,000 $ν$ interactions located in the emulsion target have been analysed. Three events with two charm decays have been observed in the neutral-current sample with an estimated background of 0.18$\pm$0.05. The relative rate of the associated charm cross-section in deep inelastic $ν$ interactions, $σ(c\bar{c}ν)/σ_\mathrm{NC}^\mathrm{DIS}= (3.62^{+2.95}_{-2.42}({stat})\pm 0.54({syst}))\times 10^{-3}$ has been measured. One event with two charm decays has been observed in charged-current $ν_μ$ interactions with an estimated background of 0.18$\pm$0.06 and the upper limit on associated charm production in charged-current interactions at 90% C.L. has been found to be $σ(c\bar{c} μ^-)/σ_\mathrm{CC} < 9.69 \times 10^{-4}$.

description: Excerpt from the report: ARS research on surface bonding Began in 1967 and is being continued at the College Station, The University of Georgia College of Agriculture Experiment Stations, Athens, Georgia. So far, this technique has been limited to one story construction. Even with one story height, long walls should be cross-braced with partitions or reinforced pilasters as required in conventional block walls. Because of relatively limited testing of the new process (2 ½ years), no guarantee can be made as to the life and durability of the surface bonding. Testing is continuing. Even if some deterioration of the glass fiber should occur due to alkaline reaction of the cement, the walls will continue to be structurally sound if tied down with rods as indicated. USDA is working with industry toward the development of a non-reactive fiber that will assure high durability and life of the bonding mix.
Identification of weak nodes in power systems
Creators: name: Dehnel, Morgan P.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes a method for determining weak nodes in power systems which may cause divergence in Newton-Raphson loadflow methods. When divergence occurs in production loadflow programs, information related to the cause of divergence is not available. The "Weak Node Method" of this thesis provides such information by identifying one or more weak nodes. The development of the Weak Node Method required extensive experimentation with the Newton-Raphson method. The behaviour of the vectors and matrices of the Newton-Raphson method during divergence are discussed in an effort to familiarize the reader with observed trends. These trends suggested the techniques which comprise the Weak Node Method. With this method, a "quasi" solution is sought first, and, secondly, three analysis procedures are then used to pinpoint the weak nodes. The method was tested using three test cases which would normally have caused the Newton-Raphson loadflow method to diverge.
Variational Theory of Mixtures in Continuum Mechanics

Year: 2008
Subjects: subject: Classical Physics (physics.class-ph)

description: In continuum mechanics, the equations of motion for mixtures are derived through the use of Hamilton's extended principle which regards the mixture as a collection of distinct continua. The internal energy is assumed to be a function of densities, entropies and successive spatial gradients of each constituent. We first write the equations of motion for each constituent of an inviscid miscible mixture of fluids without chemical reactions or diffusion. Our work leads to the equations of motion in an universal thermodynamic form in which interaction terms subject to constitutive laws, difficult to interpret physically, do not occur. For an internal energy function of densities, entropies and spatial gradients, an equation describing the barycentric motion of the constituents is obtained. The result is extended for dissipative mixtures and an equation of energy is obtained. A form of Clausius-Duhem's inequality which represents the second law of thermodynamics is deduced. In the particular case of compressible mixtures, the equations reproduce the classical results. Far from critical conditions, the interfaces between different phases in a mixture of fluids are layers with strong gradients of density and entropy. The surface tension of such interfaces is interpreted.

description: Excerpts from the report: Each year more than a million acres of land in the United States are converted from agricultural use to urban use. These changing acres are the sites for the new houses, shopping centers, schools, industrial parks, highways, and airports needed by our growing population. These changing acres also are the source of much of the sediment that pollutes streams and rivers and fills lakes and reservoirs. Studies show that erosion on land going into use for highways, houses, or shopping centers is about 10 times greater than on land in cultivated row crops, 200 times greater than on land in pasture, and 2,000 times greater than on land in timber.

description: We have known for more than thirty years that black holes behave as thermodynamic systems, radiating as black bodies with characteristic temperatures and entropies. This behavior is not only interesting in its own right; it could also, through a statistical mechanical description, cast light on some of the deep problems of quantizing gravity. In these lectures, I review what we currently know about black hole thermodynamics and statistical mechanics, suggest a rather speculative "universal" characterization of the underlying states, and describe some key open questions.

Control of the magnon current by the polarization and angle of incidence of the laser is demonstrated. Experimental detection by sizeable inverse spin Hall voltages in platinum contacts is proposed.

Abortion, potentiality, and the right to life
Creators: name: Thiessen, Eric Paul
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is about potentiality theory and the right to life. It is an attempt to distil the potentiality position into its strongest incarnation in order to see what it has to offer. In Chapter I various attempts to discredit potentiality theory are examined. Particular emphasis is placed on Michael Tooley's defense of abortion and infanticide and his critique of potentiality theory. It is concluded that a well articulated potentiality position need not lead to any obvious absurdity, and can resist the charge of philosophical arbitrariness. Thus, the potentiality position is a legitimate contender in the right to life dispute. In Chapter II, we ask the question whether the potential to become a person is sufficient for the right to life, or is actual personhood necessary? Various attempted resolutions are considered and rejected. It is concluded that the issue is still quite debateable but that some support for the potentiality position can be found in a Rawls-type validation procedure.

description: Abstract

Purpose - This paper concentrates on the Artificial Intelligence based e-vehicle market in INDIA. Every day we discuss the importance of E-Vehicles as trend seter in present Indian Market and what way the government support towards enacting laws to encourage the use of electric vehicles will lessen reliance on fossil fuels like crude oil or compressed natural gas, cut pollution, eliminate greenhouse gas emissions, enhance air quality, and safeguard the environment. Because metropolitan areas are a major source of pollution, it is crucial that residents there realize the risks associated with their consumption of pollutants and gasses that could be fatal and take steps to minimize it. The primary goal of this article is to document the opinions, feelings, difficulties, and perceptions of market participants, including manufacturers, distributors, and end users, regarding their awareness of and preparedness to select electric vehicles in order to save the environment. Findings: Based on the results of this study, we are able to conclude that the chi-square test fails to reject the null hypothesis. It implies that the null hypothesis must be accepted. The null hypothesis states that considerable people favor electric vehicles. It indicates that consumers favor electric vehicles more. All things considered, we can state that consumers prefer electric vehicles.

description: Drawing inspiration from bilayer graphene, this paper introduces its photonic analog comprising two stacked graphene-like photonic crystals, that are coupled in the near-field through spoof surface plasmons. Beyond the twist degree of freedom that can radically alter the band structure of the bilayer photonic graphene, the photonic dispersion can be also tailored via the interlayer coupling which exhibits an exponential dependence on the distance between the two photonic crystals. We theoretically, numerically, and experimentally characterize the band structures of AA- and AB-stacked bilayer photonic graphene, as well as for twisted bilayer photonic graphene with even and odd sublattice exchange symmetries. Furthermore, we numerically predict the existence of magic angles in bilayer photonic graphene, which are associated with ultra-flat bands resulted from interlayer hybridization. Finally, we demonstrate that the bilayer photonic graphene at a particular twist angle satisfying even sublattice exchange symmetry is a high-order photonic topological insulator. The proposed bilayer photonic graphene could constitute a useful platform for identifying new quantum materials and inspiring next-generation photonic devices with new degrees of freedom and emerging functionality.

The high mass end of the Tully-Fisher relation

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: We study the location of massive disk galaxies on the Tully-Fisher relation. Using a combination of K-band photometry and high-quality rotation curves, we show that in traditional formulations of the TF relation (using the width of the global HI profile or the maximum rotation velocity), galaxies with rotation velocities larger than 200 km/s lie systematically to the right of the relation defined by less massive systems, causing a characteristic `kink' in the relations. Massive, early-type disk galaxies in particular have a large offset, up to 1.5 magnitudes, from the main relation defined by less massive and later-type spirals. The presence of a change in slope at the high-mass end of the Tully-Fisher relation has important consequences for the use of the Tully-Fisher relation as a tool for estimating distances to galaxies or for probing galaxy evolution. In particular, the luminosity evolution of massive galaxies since z = 1 may have been significantly larger than estimated in several recent studies. We also show that many of the galaxies with the largest offsets have declining rotation curves and that the change in slope largely disappears when we use the asymptotic rotation velocity as kinematic parameter. The remaining deviations from linearity can be removed when we simultaneously use the total baryonic mass (stars + gas) instead of the optical or near-infrared luminosity. Our results strengthen the view that the Tully-Fisher relation fundamentally links the mass of dark matter haloes with the total baryonic mass embedded in them.

The low dimensionality and strong correlations of 2D systems give rise to electronic and structural properties, in the form of collective excitations, that do not have counterparts in ordinary 3D materials used in modern technology. These 2D materials present extraordinary opportunities for new technologies, such as in flexible electronics. In this Review, we focus on plasmons, excitons, phonons and magnons in 2D materials. We discuss the theoretical formalism of these collective excitations and elucidate how they differ from their 3D counterparts.

description: Surfaces inspired by nature and their replication find great interest in science, technology, and medicine due to their unique functional properties. This research aimed to develop an efficient laser milling technology using single-pulse- and burst-modes of irradiation to replicate bio-inspired structures over large areas at high speed. The ability to form the trapezoidal-riblets inspired by shark skin at high production speeds while maintaining the lowest possible surface roughness was demonstrated.

description: AIMS: We investigate here the nature of all the sources (35 in total) in the XBS survey (which is 86% optically identified) showing an optical spectrum dominated by the light from the host galaxy with no evidence (or little evidence) for the presence of an AGN. METHODS: We use the X-ray spectral analysis to assess the presence of an AGN in these sources and to characterize its properties. RESULTS: We detect AGN activity in 33 out of 35 sources. The remaining 2 sources are the ones with the lowest X-ray luminosity in the sample (L[2-10keV]<10^41 erg s^-1) and their X-ray emission could be produced within the host galaxy. We find that the ``recognition problem'' for AGN is very critical in the low-luminosity regime (at least 60% of the AGN with L[2-10keV]<10^43 erg s^-1 are elusive) becoming negligible for high X-ray luminosities (~1.5% of elusive AGN with L[2-10keV]>10^44 erg s^-1). This problem affects mostly absorbed AGN (~40% of type~2 AGN in the survey are elusive) but also a significant fraction of unabsorbed AGN (8%). CONCLUSIONS: We find that the simplest explanations of why these 33 (or most of them) AGNs are elusive are two: at low X-ray luminosities (<10^43 erg s^-1) the most important reason is the intrinsically low AGN/galaxy contrast (optical dilution) while at high luminosities (>10^44 erg s^-1) it is due to the optical absorption (in the Compton-thin regime, i.e. NH<10^24 cm^-2). Alternative hypotheses, like the presence of Compton-thick sources, BL Lac objects or ``non-standard'' AGN (e.g. with alpha_OX<1 or with weak/absorbed Narrow Line Region) are not supported by the data although we cannot exclude the presence in the sample of a few sources of these types.

Probing minimal supergravity in the type-I seesaw mechanism with lepton flavour violation at the CERN LHC

description: The most general supersymmetric seesaw mechanism has too many parameters to be predictive and thus can not be excluded by any measurements of lepton flavour violating (LFV) processes. We focus on the simplest version of the type-I seesaw mechanism assuming minimal supergravity boundary conditions. We compute branching ratios for the LFV scalar tau decays, ${\tilde τ}_2 \to (e,μ) + χ^0_1$, as well as loop-induced LFV decays at low energy, such as $l_i \to l_j + γ$ and $l_i \to 3 l_j$, exploring their sensitivity to the unknown seesaw parameters. We find some simple, extreme scenarios for the unknown right-handed parameters, where ratios of LFV branching ratios correlate with neutrino oscillation parameters. If the overall mass scale of the left neutrinos and the value of the reactor angle were known, the study of LFV allows, in principle, to extract information about the so far unknown right-handed neutrino parameters.

A close reading of L'Année dernière à Marienbad by Alain Robbe-Grillet
Creators: name: Schofer, Drew Christopher
Publisher: name: University of British Columbia
Year: 2010

description: L'Année Dernière à Marienbad is a narrative film which plays with Appearance and Reality in a baroque fashion. This thesis is an attempt to come to terms with the Marienbad world view. In the introduction are discussed the arguments against the film as expressed by Pauline Kael, as well as the commentary style of my critical approach. In the first chapter we are faced with film as high art, as the camera takes us on an architectural tour of a baroque chateau while a nameless narrator describes the set. Eventually the voice is revealed to be that of an actor in a play. In the audience discussing this play we meet our three protagonists: A, a mysterious woman; M, a man who may be her husband; and X, a man who tries to persuade her to leave with him. We are teased by meaning and symbolism at every turn as we await the plot of our story to unfold. Chapter two takes us to the gardens where we are presented a statue of a man, woman and dog. X evokes scenes from A's and his "shared" past. The style of Marienbad's editing replaces traditional Hollywood Découpage with a version its creators believe to be closer to reality as it should be presented on film. A possible reason for the number of detractors of Marienbad is discovered to be the inherent passive aggression present in the film. The final chapter outlines X's search for an ending and discusses our reactions to these various solutions. The conclusion compares the ending from Resnais's Hiroshima Mon Amour to the end of Marienbad presenting the timeless reality of fictitious film. The search for a conclusion or answer to the riddle of Marienbad however remains elusive. We are invited to encounter possibilities as often as we, an audience, encounter L'Année Dernière à Marienbad.
Absorption Line Survey of H3+ toward the Galactic Center Sources II. Eight Infrared Sources within 30 pc of the Galactic Center

description: Infrared absorption lines of H3+, including the metastable R(3,3)l line, have been observed toward eight bright infrared sources associated with hot and massive stars located in and between the Galactic Center Cluster and the Quintuplet Cluster 30 pc to the east. The absorption lines with high velocity dispersion arise in the Galaxy's Central Molecular Zone (CMZ) as well as in foreground spiral arms. The temperature and density of the gas in the CMZ, as determined from the relative strengths of the H3+ lines, are T=200-300K and n=50-200cm^-3. The detection of high column densities of H3+ toward all eight stars implies that this warm and diffuse gaseous environment is widespread in the CMZ. The products of the ionization rate and path length for these sight lines are 1000 and 10 times higher than in dense and diffuse clouds in the Galactic disk, respectively, indicating that the ionization rate, zeta, is not less than 10^-15 s^-1 and that L is at least on the order of 50 pc. The warm and diffuse gas is an important component of the CMZ, in addition to the three previously known gaseous environments: (1) cold molecular clouds observed by radio emission of CO and other molecules, (2) hot (T=10^4-10^6K) and highly ionized diffuse gas (n_e=10-100cm^-3) seen in radio recombination lines, far infrared atomic lines, and radio-wave scattering, and (3) ultra-hot (T=10^7-10^8K) X-ray emitting plasma. Its prevalence significantly changes the understanding of the environment of the CMZ. The sight line toward GC IRS 3 is unique in showing an additional H3+ absorption component, which is interpreted as due to either a cloud associated with circumnuclear disk or the "50 km s^-1 cloud" known from radio observations. An infrared pumping scheme is examined as a mechanism to populate the (3,3) metastable level in this cloud.

description: We have performed depth dependent muon spin rotation/relaxation studies of the dynamics of single layer films of {\it Au}Fe and {\it Cu}Mn spin glasses as a function of thickness and of its behavior as a function of distance from the vacuum interface (5-70 nm). A significant reduction in the muon spin relaxation rate as a function of temperature with respect to the bulk material is observed when the muons are stopped near (5-10 nm) the surface of the sample. A similar reduction is observed for the whole sample if the thickness is reduced to e.g. 20 nm and less. This reflects an increased impurity spin dynamics (incomplete freezing) close to the surface although the freezing temperature is only modestly affected by the dimensional reduction.
Cosmology with Galaxy Correlations
Creators: name: Nichol, Robert C.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In this review, I outline the use of galaxy correlations to constrain cosmological parameters. As with the Cosmic Microwave Background (CMB), the density of dark and baryonic matter imprints important scales on the fluctuations of matter and thus the clustering of galaxies, e.g., the particle horizon at matter--radiation equality and the sound horizon at recombination. Precision measurements of these scales from the Baryon Acoustic Oscillations (BAO) and the large scale shape of the power spectrum of galaxy clustering provide constraints on Omega_m h^2. Recent measurements from the Sloan Digital Sky Survey (SDSS) and 2dF Galaxy Redshift Survey (2dFGRS) strongly suggest that Omega_m < 0.3. This forms the basic evidence for a flat Universe dominated by a Cosmological Constant (Lambda) today (when combined with results from the CMB and supernova surveys). Further evidence for this cosmological model is provided by the late-time Integrated Sachs-Wolfe (ISW) effect, which has now been detected using a variety of tracers of the large scale structure in the Universe out to redshifts of z>1. The ISW effect also provides an opportunity to discriminate between Lambda, dynamical dark energy models and the modification of gravity on large scales.

From valence bond solid to unconventional superconductivity in the organic charge-transfer solids

description: We show that superconductivity is absent within the 1/2-filled band triangular lattice repulsive Hubbard model that has been proposed for organic charge-transfer solids. We posit that organic superconductivity is rather reached from a Bond-Charge Density Wave that either constitutes the insulating state proximate to superconductivity, or is extremely close in energy to the antiferromagnetic state, and replaces the latter under pressure. The Bond-Charge Density Wave can be described within an effective attractive $U$ extended Hubbard Hamiltonian with repulsive nearest neighbor interaction $V$. A first-order transition from the insulating to the superconducting state occurs within the model with increasing frustration.
