Oxidative metabolism of estrogens
Creators: name: Lewis, Joyce
Publisher: name: University of British Columbia
Year: 2011

description: This project was undertaken to obtain more information about the nature of the water-soluble metabolites formed by rat liver since these had been shown to differ from the normal conjugates found in other species and are influenced by the sex of the animal and also by compounds in the soluble fraction of the cell. A comparison was made between these products and those formed from estrogens by mushroom phenolase under similar conditions, and it was found that glutathione had the same effect as the soluble fraction of the cell in increasing the yield of water-soluble metabolites in the rat liver microsomal system. This tripeptide also competed effectively with protein-binding and proposals to account for this reaction have been put forward. A marked increase in the yield of water-soluble estrogen derivatives was also observed when glutathione was added to the phenolase system, and although a different mechanism may be involved, similar types of products were formed. A competitive reaction for protein-binding in the presence of glutathione was again demonstrated. Sulphydryl compounds such as cysteine, ergothionine, homocysteine and thiolhistidine had little or no effect in either of the two systems, and the reaction therefore appears to be specific for glutathione. Oxidized glutathione was ineffective in increasing the yield of water-soluble metabolites indicating that the sulphydryl group was involved, and N-ethylmaleimide was found to be strongly inhibitory. The effect of estrogen oxidation products on the in vitro inactivation of gonadotropins was also investigated.

description: Solid semiconductor sensors are used as detectors in high-energy physics experiments, in medical applications, in space missions and elsewhere. Minimal knowledge of the electric field inside the elementary cells of these sensors is highly important for their performance understanding. The field governs the charge propagation processes and ultimately determines the size and quality of the electronic signal of the cell. Hence, the simulation of these sensors as detectors in different analyses relies strongly on the field knowledge. For a certain voltage applied to the cell, the field depends on the specifics of the device's growth and fabrication. The information about these is often commercially protected or otherwise very difficult to encode in state-of-the-art technology computer-aided-design (TCAD) software. In this work, we show that by taking the top-down approach, combining public beam-test data and a very limited public TCAD knowledge, we are able to effectively approximate the 3D electric field function in the pixel cell of one important and widely used example, namely the ALPIDE sensor, for simulating the charge propagation processes. Despite its broad usage worldwide, the ALPIDE field is not available to the community. We provide an effective field function, that adequately describes the sensor behaviour without trying to reconstruct further details about the device or the details behind its processing. We comment on the process by which the effective field function is derived with the help of the Allpix$^2$ software, and on how similar work can be performed for other devices, starting from the same grounds.

GRB optical afterglow and redshift selection effects: The learning curve effect at work

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We show how the observed gamma ray burst (GRB) optical afterglow (OA) and redshift distributions are changing in time from selection effects. For a subset of {\it Swift} triggered long duration bursts, we show that the mean time taken to acquire spectroscopic redshifts for a GRB OA has evolved to shorter times. We identify a strong correlation between the mean time taken to acquire a spectroscopic redshift and the measured redshift. This correlation reveals that shorter response times favour smaller redshift bursts. This is compelling evidence for a selection effect that biases longer response times with relatively brighter high redshift bursts. Conversely, for shorter response times, optically fainter bursts that are relatively closer are bright enough for spectroscopic redshifts to be acquired. This selection effect could explain why the average redshift, $\approx2.8$ measured in 2005, has evolved to $\approx2$, by mid 2008. Understanding these selection effects provides an important tool for separating the contributions of intrinsically faint bursts, those obscured by host galaxy dust and bursts not seen in the optical because their OAs are observed at late times. The study highlights the importance of rapid response telescopes capable of spectroscopy, and identifies a new redshift selection effect that has not been considered previously, namely the response time to measure the redshift.

description: Structural Best Management Practices (BMPs) have been used for stormwater treatment and management for several decades. How to monitor these BMPs performance reliably and economically is a challenge. This paper reports the feasibility of developing a flow through passive sampler (PS) based on Amberlite IRC748 ion exchange resin operated in kinetic regime for sampling heavy metals in BMPs (infiltration systems) for stormwater treatment and management. Tests were conducted using batch reactors and laboratory-scale BMPs. Batch reactor results indicate that PSs performed desirably with consistent and rapid metal uptake, and thus, the resin-based PS is feasible to be used for stormwater sampling. In lab-scale BMPs tests, the resin PSs were employed for sampling influent and effluent of BMPs loaded with synthetic stormwater for storm durations of 0.5, 3, and 12 hours. The removal efficiency of heavy metals in the BMPs as predicted by PSs was very similar to the actual treatment efficiencies obtained from control BMPs, with errors ranging from –5% to 2%, indicating that the PSs can be used for sampling stormwater and monitoring BMPs. The next step for this sampler will be to develop a method for evaluating the volume of water passing the PS during the sampling period.

description: Puffy disc is a numerical model, expected to capture the properties of the accretion flow in X-ray black hole binaries in the luminous, mildly sub-Eddington state. We fit the kerrbb and kynbb spectral models in XSPEC to synthetic spectra of puffy accretion discs, obtained in general relativistic radiative magnetohydrodynamic simulations, to see if they correctly recover the black hole spin and mass accretion rate assumed in the numerical simulation. We conclude that neither of the two models is capable of correctly interpreting the puffy disc parameters, which highlights a necessity to develop new, more accurate, spectral models for the luminous regime of accretion in X-ray black hole binaries. We propose that such spectral models should be based on the results of numerical simulations of accretion.

description: Nonlinear optics has been a very dynamic field of research with spectacular phenomena discovered mainly after the invention of lasers. The combination of high intensity fields with resonant systems has further enhanced the nonlinearity with specific additional effects related to the resonances. In this paper we review a limited range of these effects which has been studied in the past decades using close-to-room-temperature atomic vapors as the nonlinear resonant medium. In particular we describe four-wave mixing (4WM) and generation of nonclassical light in atomic vapors. One-and two-mode squeezing as well as photon correlations are discussed. Furthermore, we present some applications for optical and quantum memories based on hot atomic vapors. Finally, we present results on the recently developed field of quantum fluids of light using hot atomic vapors.

Nuclear Structure

description: Deformation of nuclei is present across the nuclear landscape. With the use of experimental techniques, such as Coulomb excitation, this property of nuclei can be probed further and thus can provide a more complete picture of their structure. Lying between two magic number shell closures of 28 and 50, the N ≈ Z ≈ 40 region of the nuclear chart has long been associated with strongly deformed nuclear shapes. The strong deformation present in this area has been confirmed through studies of the lifetimes of N ≈ Z Sr and Zr nuclei. Recent theoretical calculations predict near prolate axial deformation for N = Z and N = Z+2 nuclei between N = Z = 36 and N = Z = 40 (76,78Sr and 80Zr). 80Sr is on the edge of this predicted axially prolate region. In this work, Coulomb excitation of 80Sr was carried out. The first experimental measurement of the spectroscopic quadrupole moment for 80Sr is shown in this work to be Qs(2+1) = 0.45±0.83 0.88 eb. This measurement of Qs is inconsistent with theoretical predictions. As such, this points to the expected region of axially prolate nuclei having somewhat sharply defined edges around the quartet of nuclei: 76,78Sr and 78,80Zr. Further along the nuclear chart, neutron-rich Sr, Zr, and Mo nuclei have been observed to undergo a dramatic evolution, becoming strongly deformed around N = 60. This is sometimes interpreted as a quantum phase transition between “normal” and intruder configurations. A key to understanding this evolution is to observe the configurations in isolation, in regions where this interference can be neglected. A deformed coexisting configuration is inferred from the presence of a 0+2state which decreases in excitation energy with increasing neutron number, which becomes the first-excited state of 98Mo. Another part of this work covers the results of the Coulomb excitation of 96Mo. The values extracted are for B(E2) and spectroscopic quadrupole moments. While in agreement with the literature values of B(E2), there is a significant disagreement with the literature spectroscopic quadrupole moments. The presented results are compared with shell-model calculations using an 88Sr core with a good agreement found, likely indicating that intruder structures do not significantly impact the ground-state structure, in contrast with

description: Technology in agriculture has changed more in the past hundred years than in the previous thousand, and the rate of change seems to be accelerating. No longer can one farm successfully for the duration of a lifetime with the same knowledge, understanding and skill which he possessed as a young farmer (1).
Senators and representatives recognized the need for the continuous preparation of farm people for proficiency in their chosen field and in 1917 introduced and passed the Smith-Hughes Act. This enabled school administrators to offer vocational instruction in agriculture to young and adult farmers by providing additional funds to local districts for classes in vocational education. The act also provided for agriculture education in the high school curriculum (15).

description: Motivated by the recent experimental realization of ultracold quantum gases in shell topology, we propose a straightforward implementation of matter-wave lensing techniques for shell-shaped Bose-Einstein condensates. This approach allows to significantly extend the observation time of the condensate shell during its free expansion and enables the study of novel quantum many-body effects on curved geometries. With both analytical and numerical methods we derive optimal parameters for realistic lensing schemes to conserve the shell shape of the condensate for times up to hundreds of milliseconds.

description: The oblate-prolate shape coexisting/mixing phenomena in proton-rich 68,70,72Se are investigated by means of the adiabatic self-consistent collective coordinate (ASCC) method. The one-dimensional collective path and the collective Hamiltonian describing the large-amplitude shape vibration are derived in a fully microscopic way. The excitation spectra, B(E2) and spectroscopic quadrupole moments are calculated by requantizing the collective Hamiltonian and solving the collective Schroedinger equation. The basic properties of the coexisting two rotational bands in low-lying states of these nuclei are well reproduced. It is found that the oblate-prolate shape mixing becomes weak as the rotational angular momentum increases. We point out that the rotational energy plays a crucial role in causing the localization of the collective wave function in the (beta,gamma) deformation space.

description: The present article is the last in a series of five devoted to the study of the effect of anisotropic pressure on the gravitationnal impact of a stationary rigidly rotating cylindrically symmetric fluid with the use of new exact solutions of General Relativity. In the four first papers in this series, three kinds of pressures directed each along one of the principal stresses of the fluid have been considered and new interior solutions of the field equations have been constructed and analyzed. Here, key results and issues raised in these previous works are synthesized and some fundamental notions of general relativity, causality, regularity of Lorentzian manifolds, elementary flatness in the vicinity of a symmetry axis, singularities, physics of angular deficits, weak and strong energy conditions, are revisited. Then, a new derivation of the corresponding dust solution is displayed and shown to correspond indeed to the Lanczos-van Stockum solution shedding new light to this well-known spacetime.

description: To date over 4000 exoplanets have been identified and thousands of candidates are to be confirmed. Our knowledge of exoplanets is expanding in the Galaxy, from the solar neighborhood (~0.1 kpc) to several kpc away. What are the differences between planetary systems in different galactic environments, and how do they evolve with time? To address these questions, we conduct a research project, dubbed Planets Across Space and Time (PAST). In this talk, we present some first results of the PAST. We revisit the kinematic method for classification of Galactic components and extend the applicable range of velocity ellipsoid from ∼100 pc to ∼1500 pc from the Sun. Furthermore, we revisited the age–velocity dispersion relation (AVR), which allows us to derive kinematic ages with a typical uncertainty of 10–20%. Applying the above revised methods, we present catalogs of kinematic properties as well as other basic stellar parameters for 2174 host stars of 2872 planets and 35,864 Kepler stars by combining data from Gaia, LAMOST, APOGEE, RAVE, Kepler, and the NASA exoplanet archive. We find that the fraction of thin (thick) disk stars increases (decreases) with the transiting planet multiplicity (Np = 0, 1, 2 and 3+) and the kinematic age decreases with Np, which could be a consequence of the dynamical evolution of planetary architecture with age. The revised kinematic method and AVR, as well as the kinematic catalogs, lay the foundation for future studies of exoplanets in space and time in the Galactic context.

description: Observed X-ray spectra of some isolated magnetized neutron stars display absorption features, sometimes interpreted as ion cyclotron lines. Modeling the observed spectra is necessary to check this hypothesis and to evaluate neutron star parameters.We develop a computer code for modeling magnetized neutron star atmospheres in a wide range of magnetic fields (10^{12} - 10^{15} G) and effective temperatures (3 \times 10^5 - 10^7 K). Using this code, we study the possibilities to explain the soft X-ray spectra of isolated neutron stars by different atmosphere models. The atmosphere is assumed to consist either of fully ionized electron-ion plasmas or of partially ionized hydrogen. Vacuum resonance and partial mode conversion are taken into account. Any inclination of the magnetic field relative to the stellar surface is allowed. We use modern opacities of fully or partially ionized plasmas in strong magnetic fields and solve the coupled radiative transfer equations for the normal electromagnetic modes in the plasma. Spectra of outgoing radiation are calculated for various atmosphere models: fully ionized semi-infinite atmosphere, thin atmosphere, partially ionized hydrogen atmosphere, or novel "sandwich" atmosphere (thin atmosphere with a hydrogen layer above a helium layer. Possibilities of applications of these results are discussed. In particular, the outgoing spectrum using the "sandwich" model is constructed. Thin partially ionized hydrogen atmospheres with vacuum polarization are shown to be able to improve the fit to the observed spectrum of the nearby isolated neutron star RBS 1223 (RX J1308.8+2127).

description: Recent theories and experiments have suggested that strong spin-orbit coupling effects in certain band insulators can give rise to a new phase of quantum matter, the so-called topological insulator, which can show macroscopic entanglement effects. Such systems feature two-dimensional surface states whose electrodynamic properties are described not by the conventional Maxwell equations but rather by an attached axion field, originally proposed to describe strongly interacting particles. It has been proposed that a topological insulator with a single spin-textured Dirac cone interfaced with a superconductor can form the most elementary unit for performing fault-tolerant quantum computation. Here we present an angle-resolved photoemission spectroscopy study and first-principle theoretical calculation-predictions that reveal the first observation of such a topological state of matter featuring a single-surface-Dirac-cone realized in the naturally occurring Bi$_2$Se$_3$ class of materials. Our results, supported by our theoretical predictions and calculations, demonstrate that undoped compound of this class of materials can serve as the parent matrix compound for the long-sought topological device where in-plane surface carrier transport would have a purely quantum topological origin. Our study further suggests that the undoped compound reached via n-to-p doping should show topological transport phenomena even at room temperature.

It can be viewed either as a group field theory over the additive group of a vector space or as an asymptotic expansion of any group field theory around the unit group element. We prove exact power counting theorems for any graph of such models. For linearized colored models the power counting of any amplitude is further computed in term of the homology of the graph. An exact power counting theorem is also established for a particular class of graphs of the nonlinearized models, which satisfy a planarity condition. Examples and connections with previous results are discussed.

description: Recent studies on organic thin-film transistors (OTFTs) have reported high mobility values, but many of them showed non-ideal current–voltage characteristics that could lead to the overestimation of the mobility values. In this study, the non-ideal transistor behavior was briefly investigated by considering the effect of charge injection, and a method of overcoming the effect was developed. Correspondingly, various charge injection layers were developed, and their effects on the modification of metal contacts, including work function tuning and interfacial doping, were studied. The materials that had been coated formed a good metal-semiconductor interface through fine manipulation in the wetting and dewetting of the selected liquid. With such electrodes, the OTFTs were fabricated at room temperature and exhibited almost ideal transistor behavior in terms of the current–voltage characteristics, featuring high (over 10 cm2/Vs) field-effect mobility.
Comparison of Vertebrate Collagenase and Gelatinase Using a New Fluorogenic Substrate Peptide.

description: A fluorogenic substrate for vertebrate collagenase and gelatinase,Dnp-Pro-Leu-Gly-Leu-Trp-Ala-D-Arg-NH2,was designed using structure-activity data obtained from studies with synthetic inhibitors and other peptide substrates of collagenase. Tryptophan fluorescence was efficiently quenched by the NH2-terminal dinitrophenyl group,presumably through resonance energy transfer. Increased fluorescence accompanied hydrolysis of the peptide by collagenase or gelatinase purified from culture medium of porcine synovial membranes or alkali-treated rabbit corneas. Amino acid analysis of the two product peptides showed that collagenase and gelatinase cleaved at the Gly-Leu bond. The peptide was an efficient substrate for both enzymes,with kcat/Km values of 5.4 microM-1 h-1 and 440 microM-1 h-1 (37 degrees C,pH 7.7) for collagenase and gelatinase,respectively. Under the same conditions,collagenase gave kcat/Km of about 46 microM-1 h-1 for type I collagen from calf skin. Since both enzymes exhibited similar Km values for the synthetic substrate (3 and 7 microM,respectively),the higher catalytic efficiency of gelatinase reflects predominantly an increase in kcat. Both enzymes were inhibited by HSCH2(R,S)CH[CH2CH(CH3)2]CO-L-Phe-L-Ala-NH2 in this assay (50% inhibition at 20 nM and less than 1 nM for collagenase and gelatinase,respectively). Soluble type I collagen was a competitive inhibitor of peptide hydrolysis by collagenase (KI = 0.8 microM) and exhibited mixed inhibition of gelatinase (KI = 0.3 microM).

description: In recent work, we developed a screening theory for describing the effect of plastic events in amorphous solids on its emergent mechanics. The suggested theory uncovered an anomalous mechanical response of amorphous solids where plastic events collectively induce distributed dipoles that are analogous to dislocations in crystalline solids. The theory was tested against various models of amorphous solids in two-dimensions, including frictional and friction-less granular media and numerical models of amorphous glass. Here we extend our theory to screening in three-dimensional amorphous solids and predict the existence of anomalous mechanics similar to the one observed in two-dimensional systems. We conclude by interpreting the mechanical response as the formation of non-topological distributed dipoles that have no analogue in the crystalline defects literature. Having in mind that the onset of dipole screening is reminiscent of Kosterlitz-Thouless and Hexatic transitions, the finding of dipole screening in three-dimensions is particularly novel.

description: Approximately 46 million acres or 88 per cent of the land area of the state of Utah has been classified by Reuss and Blanch (1951) as "range land open for grazing." Although some of this area cannot be grazed because of inaccessibility, lack of water, poison plants, and similar factors, it is estimated that some 40 million acres or 78 per cent of the total land area is available for grazing. Most of this grazing land is federally owned (73 per cent), while only 22 per cent is privately held, and 5 per cent is state owned.

description: During the last two decades, Utah's market milk industry has changed from one of local processing and distribution by small-scale plants to one of state-wide distribution by large-scale dairies. At present, four large producer cooperatives control most of the state's market milk and six large processing plants accounts for more than 80 percent of the state's fluid milk sales.
Along with centralized processing and distribution has also come some centralization of production. Statistics recently published by Utah State University show that in 1957, 56 percent of the market milk produced in the state came from the five counties of Cache, Utah, Weber, Salt Lake, and Summit (13, p. 8)*. These same five counties accounted for over 50 percent of the increase in total production of market milk between 1948 and 1957 (13, p.9).

The female usually has the last tergite convex and fi nely pubescent, the pygidial area is delimited only in shestakovi, and vaguely so in some specimens of nanus. The sternites of the male are not distinctly modi fi ed, although slight differences may be discovered in the pilosity or puncturation. The clypeus always lacks a median tooth (but one African species has in its place a tubercle or small transverse projection). Its anterior margin is not cut out for the labrum, although short and blunt submedian teeth are often present. The upper face is without an orbital fovea. The oral fossa is broadly V-shaped as hypostomal carinae diverge in a more or less obtuse angle anteriorly reaching the base of the mandibles, and with the hypostome more or less sloping.
The pterostigma is bicolorous in Palaearctic species, except in some specimens of shestakovi which have generally very pale venation (fi gure 68) and in two Madagascan species. One Madagascan species has the mandibles pointed, without the upper apical tooth, another Afro-Mediterranean species has a short lobe at the base of lower edge of the mandible (fi gure 58) and yet another has a blunt tubercle outside the oral fossa on the underside of the head.
Whilst in the Palaerarctic region only a few species belong to Ammoplanellus, in the Afrotropical region, except the South African mandibularis Cameron, all belong to this subgenus. However, fi ve Madagasca n species exhibit a horizontal (subscrobal) crenulate groove on the mesepimeron. The importance of this character is still uncertain, but could be used to help delimit another subgenus.

description: Magnetic topological materials and their physical signatures are a focus of current research. Here, by first-principles calculations and symmetry analysis, we reveal topological semimetal states in an existing antiferromagnet ThMn2Si2. Depending on the Néel vector orientation, the topological band crossings near the Fermi level form either a double-nodal loop or two pairs of Dirac points,which are all fourfold degenerate and robust under spin-orbit coupling. These topological features produce large Berry connection polarizability, which leads to enhanced nonlinear transport effects. Particularly, we evaluate the third order current response, which dominates the transverse charge current. We show that the nonlinear response can be much more sensitive to topological phase transitions than linear response, which offers a powerful tool for characterizing magnetic topological semimetals.

description: Ischemic cerebral stroke is a severe cause of human death and disability. Natural products play an important role in the discovery of novel therapy for cerebral ischemia. Herein, we investigate the neuroprotective effects of sikokianin A identifiedfrom Wikstroemia indica using PC12 cell exposed to OGD/R. The results revealed sikokianin A can improve the poor viability and release of intracellular LDH in PC12 cells induced by OGD/R. Further studies have demonstrated the increased ROS and MDA together with reduced SOD activity were attenuated by sikokianin A. Meanwhile, decreased mitochondrial membrane potential, activated Caspase-3, down-regulated Bcl-2 and up-regulated Bax were reversed. These results indicate the protective effects of sikokianin A are associated with inhibiting oxidative stress and apoptosis resulting from OGD/R. Additionally, sikokianin A can activate Nrf2 and downstream HO-1 in PC12 cells treated by OGD/R, which implied Nrf2/HO-1 signaling pathway was involved in the protective effects of sikokianin A.

The Battered Child Syndrome : medical, legal and social work machinery for dealing with the Battered Child Syndrome
Creators: name: Atkinson, Raymond Gareth
Publisher: name: University of British Columbia
Year: 2011

description: The focus of this thesis is to assess the existing "machinery" of the Medical, Social Work and Legal professions in the Vancouver area, as they combine their services to cope with the recently identified problem of the Battered and Abused Child Syndrome. Knowledge of this social problem is of paramount importance in the field of child protection as the greater proportion of victims are babies of three months and younger. The swiftness and destructiveness of this syndrome, which sometimes results in death to the victim, makes early detection and immediate protection of the child imperative. Therefore the three affected professions in each community must devise a definite and cooperative pattern of response to the syndrome. Each profession must shoulder a share of the responsibility as the services of all three are necessary for the ultimate goal of protection for a helpless child. A three-pronged approach involving each discipline was selected. Piles of victims were provided for examination by a local hospital and child protection agency. Information was transferred to a predesigned schedule, and tables constructed depicting injuries and other characteristics of the victims and also common parental traits within the battering families. Due to the time element and difficulty in locating actual cases that had been before the courts, examination as to legal involvement was restricted to case studies. Results of the study indicate that present machinery is adequate and that each discipline has become more adept and thorough at, handling such situations within the last few years. Definite recognition must be given to the planned establishment of a Battered Child Registry in Victoria. The Protection of Children Act is, as it stands, a proper vehicle for bringing cases of battered children before the court. Individual professionals must be aware of any subjective emotional reaction that could prevent their objective handling of such cases. This is one social problem in which rehabilitation and treatment of the family must take a subordinate position to the absolute protection of a single family member. Medical evidence in court should be focused on establishing persistence of abuse, and social work evidence should portray the existence of an unsafe environment. More follow up work must be done with the families even after permanent removal of a child, in hopes of rendering the family safe for the care of future children. The emotional impact felt by the family on the removal of such a child is yet to be documented and resultant behavior noted. Care must be taken by Child Welfare authorities to follow the emotional development of the victims, documenting the resultant adult personality type and any treatment found necessary during the formative years and its degree of success.
title: Economics of Farm Flock Sheep Production in Northern Utah
Creators: name: Nielson, Bruce E.
Publisher: name: Utah State University
Year: 1961

description: Throughout the history of mankind, sheep have played a very important and unique part in the economies of the world. They have been a source of meat, milk, skins and fiber. They have become adapted to nearly every kind of husbandry, from nomadic types to intensively managed flocks on small farms and have thrived under nearly all climatic conditions, ranging from sub-artic regions of Greenland to hot areas of the mediterranean countries; from desert areas of Africa to wet lowland of England.
Domestic sheep were introduced on the American continent by Spanish discovered and conquerors in 1493. (8, p.281) The other route by which they came was from England in 1607. (e, p. 21)

description: Bosonic Gaussian states are a special class of quantum states in an infinite dimensional Hilbert space that are relevant to universal continuous-variable quantum computation as well as to near-term quantum sampling tasks such as Gaussian Boson Sampling. In this work, we study entanglement within a set of squeezed modes that have been evolved by a random linear optical unitary. We first derive formulas that are asymptotically exact in the number of modes for the Rényi-2 Page curve (the average Rényi-2 entropy of a subsystem of a pure bosonic Gaussian state) and the corresponding Page correction (the average information of the subsystem) in certain squeezing regimes. We then prove various results on the typicality of entanglement as measured by the Rényi-2 entropy by studying its variance. Using the aforementioned results for the Rényi-2 entropy, we upper and lower bound the von Neumann entropy Page curve and prove certain regimes of entanglement typicality as measured by the von Neumann entropy. Our main proofs make use of a symmetry property obeyed by the average and the variance of the entropy that dramatically simplifies the averaging over unitaries. In this light, we propose future research directions where this symmetry might also be exploited. We conclude by discussing potential applications of our results and their generalizations to Gaussian Boson Sampling and to illuminating the relationship between entanglement and computational complexity.

description: The production of livestock in Utah is important to the economy of the state. The economic life of many communities throughout the state depends on income from livestock. Cash receipts from range livestock were $62.7 million or 38.8 percent of the total from agriculture in Utah in 1958 (18).
Much land in Utah is used almost exclusively for livestock production. Of the 52.7 million acres in Utah about 78 percent is used for the production of range livestock (15). Sheep obtain approximately 86 percent and cattle 56 percent of their forage needs from range lands (15, p.28). Although there are alternative uses for some areas, grazing livestock is the only significant economic use for much range land in the state.
