description: In this work, a new generic parameterisation for $f(R)$ theories is presented. Our proposal for a new equation of state can reproduce an $f(R)$-like evolution that describes late and early time universe within 1-$σ$ C.L when we use a combination of distance ladder measurements based on Cosmic Chronometers, Supernovae Ia, Baryon Acoustic Oscillation and finally, Cosmic Microwave Background and Lyman-$α$ forest. Indeed, a family of $f(R)$ cosmological viable scenarios were extensively analysed in the light of late-time measurements, were an Eos reaches a precision better than $99.2\%$ over the numerical solutions for the field equations of this theory. Moreover, in this proposal we extended the study to find constraints at the very early time that can satisfy the Big Bang Nucleosynthesis data on helium fraction, $Y_{p}$. To perform this analysis, and with our generic $w_{f(R)}$ --which can be seemed it at the same level as other parameterisations into the pipeline and analysis of observational surveys-- we consider both background and linear perturbations evolution and constrain beyond the standard $Λ$CDM six cosmological parameters. While there are strong constraints at background on the free parameters of our $w_{f(R)}$, we found that $f(R)$ background viable models can set early constraints to the current Hubble constant $H_0$, which is in agreement with CMB data, but when late-time model-independent measurements are considered, $H_0$ is fully compatible with the $R^{H18}$ value. Finally, as an extension of these results, our proposal is capable to distinguish between $f(R)$ scenarios at both routes of the distance ladder showing a good approach to modify gravity at this level.

Effect of peripubertal androgen treatment on hepatic cytochrome P450 expression in adult female rats
Creators: name: Anderson, Mellissa Dawn
Publisher: name: University of British Columbia
Year: 2009

description: The goal of the current study was to investigate the pubertal period as a time when androgen imprinting of hepatic CYP enzymes can occur. Female Sprague-Dawley rats were ovariectomized, at 25 days of age, and injected subcutaneously with androgens during the pubertal period, on days 35-49. Plasma testosterone levels were measured following the treatment. Rats were killed at 90 days of age and microsomes were prepared. Daily s.c. injections of testosterone enanthate at 5 umol/kg were able to increase adult testosterone 2a- and 16a- hydroxylase activities and CYP2C11 protein levels to 20% of control male levels. This enzyme is normally expressed in adult male rats only. Protein levels of CYP3A, a male-dominant enzyme, were increased 50%, although testosterone 6p-hydroxylase activity was not significantly increased. The increase in CYP3A was not attributed to CYP3A1 or CYP3A2. Neither CYP2A1 nor its marker activity, testosterone 7a-hydroxylase, was affected by pubertal testosterone enanthate injections. These results were compatible with the hypothesis that adult expression of certain CYP enzymes can be regulated by pubertal exposure to androgens. Injections of unesterified testosterone at 2.5 umol/kg twice daily had the same effect as a single dose of unesterified testosterone at 5 umol/kg/day in increasing expression of CYP2C11 and CYP3A and decreasing expression of CYP2A1. These results indicated that increases in dosing frequency of pubertal androgen to twice daily at 2.5 umol/kg did not affect adult CYP expression. Unesterified testosterone did not appear to be as effective as testosterone enanthate at elevating expression of CYP2C11 and CYP3A. This indicated a possible pharmacokinetic component, which was further supported by the difference in half-lives measured for the two androgens used. Smaller elevations in CYP2C11 and CYP3A expression were observed at 129 and 169 days of age than at 90 days of age. These results indicated that the effect of pubertal testosterone enanthate treatment was not permanent. The results of this study did not support the hypothesis of pubertal imprinting of hepatic CYP enzymes. It is likely that pharmacokinetic differences between testosterone and testosterone enanthate resulted in the varied response to the androgen formulations.

description: Intrinsic and extrinsic spin Hall effects are considered together on an equal theoretical footing for the Rashba spin-orbit coupling in two-dimensional (2D) electron and hole systems, using the diagrammatic method for calculating the spin Hall conductivity. Our analytic theory for the 2D holes shows the expected lowest-order additive result for the spin Hall conductivity. But, the 2D electrons manifest a very surprising result, exhibiting a non-analyticity in the Rashba coupling strength $α$ where the strictly extrinsic spin Hall conductivity (for $α= 0$) cannot be recovered from the $α\to 0$ limit of the combined theory. The theoretical results are discussed in the context of existing experimental results.

Parallel Algorithms for the Longest Common Subsequence Problem

description: A subsequence of a given string is any string obtained by deleting none or some symbols from the given string. A longest common subsequence of two strings is a common subsequence of both that is as long as any other common subsequences. The longest common subsequence problem is to find the longest common subsequence of two given strings. The bound on the complexity of this problem under the decision tree model is known as mn if the number of distinct symbols that can appear in strings is infinite, where m and n are the lengths of the two strings, respectively, and m ≤ n. In this paper, we propose two parallel algorithms for this problem on the CREWPRAM model. One takes O(log2 m + log n) time with mn/ log m processors, which is faster than all the existing algorithms on the same model. The other takes O(log2 m log log m) time with mn/ log2 m log log m processors when log2 m log log m > log n, or otherwise O(log n) time with mn/ log n processors, which is optimal in the sense that the time x processors bound matches the complexity bound of the problem. Both algorithms exploit nice properties of the LCS problem that are discovered in this paper.

description: We discuss the results of the MEGA microlensing campaign towards M31. Our analysis is based on an analytical evaluation of the microlensing rate, taking into account the observational efficiency as given by the MEGA collaboration. In particular, we study the spatial and time duration distributions of the microlensing events for several mass distribution models of the M31 bulge. We find that only for extreme models of the M31 luminous components it is possible to reconcile the total observed MEGA events with the expected self-lensing contribution. Nevertheless, the expected spatial distribution of self-lensing events is more concentrated and hardly in agreement with the observed distribution. We find it thus difficult to explain all events as being due to self-lensing alone. On the other hand, the small number of events does not yet allow to draw firm conclusions on the halo dark matter fraction in form of MACHOs.

description: The motivation and construction of the original Quenched Eguchi-Kawai model are reviewed, providing much greater detail than in the first, 1982 QEK paper. A 2008 article announced that QEK fails as a reduced model because the average over permutations of eigenvalues stays annealed. It is shown here that the original quenching logic naturally leads to a formulation with no annealed average over permutations.

description: Problems associated with physical interactions using aerial mobile manipulators (AMM) are being independently addressed with respect to mobility and manipulability. Multirotor unmanned aerial vehicles (UAV) are a common choice for mobility while on-board manipulators are increasingly be used for manipulability. However, the dynamic coordination between the UAV and on-board manipulator remains a significant obstacle to enable dexterous manipulation with high precision. This paper presents an AMM system configuration to addresses both the mobility and manipulability issues together. A fully-actuated UAV is chosen to achieve dexterous aerial mobile manipulation, but is limited by the actuation range of the UAV. An on-board manipulator is employed to enhance the performance in terms of dexterity and precision at the end-effector. Experimental results on position keeping of the dexterous hexrotor by withstanding the disturbances caused by the motions of the on-board manipulator and external wind disturbances are presented. Preliminary simulation results on end-point tracking in a simple planar on-board manipulator case is presented.

description: The central extension of the Thompson group $T$ that arises in the quantized Teichmüller theory is 12 times the Euler class. This extension is obtained by taking a (partial) abelianization of the so-called braided Ptolemy-Thompson group introduced and studied in \cite{FK2}. We describe then the cyclic central extensions of $T$ by means of explicit presentations.

description: The Kentucky Transportation Cabinet spends millions of dollars each year in the repairs of highway landslides. In previous research, an inventory of highway landslides showed that about 1440 landslides of various sizes exist on major roadways maintained by the Kentucky Transportation Cabinet. Moreover, emergency repairs can exceed one million dollars for large embankment failures. In many instances, drilled-in, or driven, railroad steel rails were frequently used as a stop-gap measure to halt landslide movements or those efforts were tried as a permanent solution. The use of rails to serve as a restraining structure was usually not successful when the height of fill exceeded about 20 feet. The previous study also showed about 39 percent of the landslides were small and less than 20 feet in height. Cost estimates indicated that railroad steel rails, when drilled and socketed into bedrock, may be effective and economical when the embankment height is less than about 20 feet. This study had two major objectives. Because railroad steel rails are widely used, the development of a theoretical method of analyzing and predicting the success of rails that are drilled-in and socketed into bedrock was a major objective. To enhance this method and possibly extend the height that this technique may be used, theoretical equations were developed that include the use of lightweight backfill materials, such as geofoam, shedded tires, bundled tires, “red dog,” and byproducts from coal-fired power plants. Backfill materials with different unit weights, and existing in a layered system, may be analyzed. To facilitate the use of the approach and make it widely accessible to Cabinet engineers, and as a second major objective, the theoretical algorithms were programmed in a windows computer program and stored in the Kentucky Geotechnical Database. The twelve highway district offices and main central offices of the Cabinet are connected in a client server system. For a selected factor of safety, the program predicts the success of drilled-in rails so that the user may avoid using this technique when the factor of safety is not adequate to prevent failure. However, when failure is predicted using the unit weights of ordinary soil, or rock, backfill, the program shows the thickness of geofoam (or other lightweight material) necessary to increase the factor of safety to value greater than one. The program has been checked by comparing results with results obtained from a program written by KyTC. Several examples are performed to illustrate the use of the new computer program.

description: Highway crashes have significant direct and indirect costs associated with them. Substantial sources of indirect costs are the congestion and delays that result from lane blockages or road closures while the crash is being investigated and the site cleared. In many cases, vehicles could be moved and roadways reopened very quickly, but this does not occur because of the need (or perceived need) to conduct a detailed investigation of the crash scene. The objective of this study was to identify opportunities to reduce the time required to investigate and clear crash scenes. This project includes a review of state and national best practices with a specific, detailed examination of the use of photogrammetry for reconstruction. Recommendations are presented to reduce the time taken to investigate crash sites.

description: Thermalization in highly excited quantum many-body system does not necessarily mean a complete memory loss of the way the system was formed. This effect may pave a way for a quantum computing, with a large number of qubits $n\simeq 100$--1000, far beyond the quantum chaos border. One of the manifestations of such a thermalized non-equilibrated matter is revealed by a strong asymmetry around 90$^\circ $ c.m. of evaporating proton yield in the Bi($γ$,p) photonuclear reaction. The effect is described in terms of anomalously slow cross symmetry phase relaxation in highly excited quantum many-body systems with exponentially large Hilbert space dimensions. In the above reaction this phase relaxation is about eight orders of magnitude slower than energy relaxation (thermalization).

description: Thin films of azopolymer-nanoparticles hybrid materials were fabricated with poly[1-[4-(3-carboxy-4-hydroxyphenylazo) benzenesulfonamido]-1,2-ethanediyl] (PAZO) and different concentrations of Ag and AgAu nanoparticles (NPs). By illuminating the films with polarized interference patterns, surface relief gratings (SRGs) were recorded. It was found that for some concentrations of NPs their modulations and diffraction efficiency were higher than the obtained for PAZO films without NPs. The effect was mainly explained by the increase of the free volume available for the photoisomerization for certain concentrations of NPs. The dependence of the diffraction efficiency on concentration was directly related to changes in modulation depth. When doping with NPs, the maximum efficiency increases more than two times the efficiency without NPs.

The Hatsopoulos-Gyftopoulos resolution of the Schroedinger-Park paradox about the concept of "state" in quantum statistical mechanics

description: A seldom recognized fundamental difficulty undermines the concept of individual ``state'' in the present formulations of quantum statistical mechanics (and in its quantum information theory interpretation as well). The difficulty is an unavoidable consequence of an almost forgotten corollary proved by E. Schroedinger in 1936 and perused by J.L. Park, Am. J. Phys., Vol. 36, 211 (1968). To resolve it, we must either reject as unsound the concept of state, or else undertake a serious reformulation of quantum theory and the role of statistics. We restate the difficulty and discuss a possible resolution proposed in 1976 by G.N. Hatsopoulos and E.P. Gyftopoulos, Found. Phys., Vol. 6, 15, 127, 439, 561 (1976).

description: Irritable Bowel Syndrome (IBS) is a common disorder of the gastrointestinal tract characterized by repetitive attacks of abdominal pain and discomfort in association with irregular bowel habits affecting approximately 10-20% of the global population. It not only reduces work productivity in IBS patients, but also has become one of the major socioeconomic burdens. The pathophysiology of IBS is not yet completely understood, but studies have shown that significant modification in the gut microbiota may contribute to the development and persistence of IBS. Probiotics are viable microorganisms that provide health benefits to a host by supplementing the gut microbiota and improving the microbiota characteristics. In this report, the results of the five randomized, double-blind, placebo-controlled studies are outlined that were selected from “PUBMED” and “Google Scholar” search databases to evaluate the efficacy of probiotic supplements in improving IBS symptoms. The primary outcomes for the study were IBS symptoms, abdominal pain severity (change in intensity and frequency), and quality of life, whereas the secondary outcomes included stool frequency and consistency, and satisfaction with bowel habits. The use of multi-strain probiotics is safe and effective, compared to placebo in alleviating abdominal pain and IBS symptoms severity in adult patients assessed by using both IBS-SSS and IBS-GIS scores. The review also found that Clostridium butyricum (CB) improves overall symptoms, stool frequency, and quality of life in IBS-D patients and can be employed as a probiotic in clinically treating IBS-D. In summary, the IBS symptoms severity was significantly improved in all the probiotic intervention groups which supports the effectiveness of probiotic treatment in mitigating symptoms related to IBS.

description: The objective of this study is to evaluate the use of several warning signs and warning methods to identify those that have the greatest impact on reducing vehicle speeds when traversing a horizontal curve. Three sites were selected from a list of proposed sites for the testing of the various warning methods. Each warning treatment was installed and a five-day waiting period was allowed before operating speeds for the treatments were measured. The results of the various warning methods were mixed, however, some warning treatments were able to reduce operating speeds on a consistent basis. The most effective of these treatments were the transverse lines, the new combination Horizontal Alignment/Advisory Speed sign, and flashing lights on both the existing warning sign and new combination warning sign. It should also be noted here that for all three sites, a reduction in the average of the speeds over the 85th percentile speed was observed, indicating that most of the treatments have a reducing effect on the most unsafe driving, those traveling above the 85th percentile speed.

description: We study the primordial gravitational wave background produced in models of single field inflation. Using the inflationary flow approach, we investigate the amplitude of gravitational wave spectrum in the frequency range 1 mHz - 1 Hz pertinent to future space-based laser interferometers. For models that satisfy the current observational constraint on the tensor-to-scalar ratio, r<0.36, we derive a strict upper bound of omega_{gw}<1.6 x 10^{-15}, independent of the form of the inflationary potential. Applying, in addition, the observational constraints on the spectral index and its running, omega_{gw} is expected to be considerably lower than this bound unless the shape of the potential is finely tuned. We contrast our numerical results with those based on simple power-law extrapolation of the tensor power spectrum from CMB scales. In addition to single field inflation, we summarise a number of other possible cosmological sources of primordial gravitational waves and assess what might be learnt from direct detection experiments such as LISA, Big Bang Observer and beyond.

description: In recent years the number of biological assessments (BAs) for the presence of endangered species conducted by KYTC has risen significantly. This was primarily due to new/additional restrictions imposed by the United States Fish and Wildlife Service (USFWS) in 2005. The most consequential restriction was the listing of the Indiana bat as potentially present in all Kentucky counties. Previously BAs for the Indiana bat were only conducted when a project occurred in a county in which the Indiana bat had been observed (a known occurrence). This study reviewed the policies of the states adjacent to Kentucky, as well as those of North Carolina, in regard to the conditions that produce a BA for Indiana and Gray bats. The study found that some states tend to follow different policies. But, in addition to Kentucky, four states—Indiana, Missouri, Ohio, and West Virginia— assume that the Indiana bat is potentially present in all counties of the state. These states inspect for suitable habitat for the Indiana bat on all projects. The other states only inspect when a project is in a county where the species has been observed. Regarding the gray bat, the study found that Kentucky is not disadvantaged compared to other states, as the gray bat was not said to be present in a disproportionate number of Kentucky counties. During the course of the study, KYTC developed a Programmatic Agreement with USFWS that has reduced the number of BAs.

description: A method of Parity-Time (PT)-symmetry analysis is introduced to study the high dimensional, complicated parameter space of drift wave instabilities. We show that spontaneous PT-symmetry breaking leads to the Ion Temperature Gradient (ITG) instability of drift waves, and the collisional instability is the result of explicit PT-symmetry breaking. A new unstable drift wave induced by finite collisionality is identified. It is also found that gradients of ion temperature and density can destabilize the ion cyclotron waves when PT symmetry is explicitly broken by a finite collisionality.

description: We review recent progress in calculating kaon spectrum, pseudoscalar meson decay constants, $B_K$, $ε'/ε$, $K\to ππ$ matrix elements, kaon semileptonic form factors, and moments of kaon distribution amplitudes on the lattice. We also address the issue of how best to improve the staggered fermion formulation for the action and operators.

Parametrization of a nonlocal, chiral quark model in the instantaneous three-flavor case. Basic formulas and tables

description: In these notes we describe the basic formulation of the parametrization scheme for the instantaneous nonlocal chiral quark model in the three flavor case. We choose to discuss the Gaussian, Lorentzian-type, Woods-Saxon and sharp cutoff (NJL) functional forms of the momentum dependence for the formfactor of the separable interaction. The four parameters: light and strange quark mass, coupling strength (G_S) and range of the interaction (Lambda) have been fixed by the same phenomenological inputs: pion and kaon mass, pion decay constant and light quark mass in vacuum. The Wood-Saxon and Lorentzian-type formfactor is suitable for an interpolation between sharp cutoff and soft momentum dependence. Results are tabulated for applications in models of hadron structure and quark matter at finite temperatures and chemical potentials where separable models have proven successful.

On the evolution of density perturbations in f(R) theories of gravity

description: In the context of $f(R)$ theories of gravity, we study the evolution of scalar cosmological perturbations in the metric formalism. Using a completely general procedure, we find the exact fourth-order differential equation for the matter density perturbations in the longitudinal gauge. In the case of sub-Hubble modes, the expression reduces to a second-order equation which is compared with the standard (quasi-static) equation used in the literature. We show that for general $f(R)$ functions the quasi-static approximation is not justified. However, for those functions adequately describing the present phase of accelerated expansion and satisfying local gravity tests, it provides a correct description for the evolution of perturbations.

Sigma exchange in the nuclear force and effective field theory

Publisher: name: arXiv
Year: 2006
Subjects: subject: Nuclear Theory (nucl-th)
subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In the phenomenological description of the nuclear interaction a crucial role is traditionally played by the exchange of a scalar I=0 meson, the sigma, of mass 500-600 MeV, which however is not seen clearly in the particle spectrum and which has a very ambiguous status in QCD. I show that a remarkably simple and reasonably controlled combination of ingredients can reproduce the features of this part of the nuclear force. The use of chiral perturbation theory calculations for two pion exchange supplemented by the Omnes function for pion rescattering suffices to reproduce the magnitude and shape of the exchange of a supposed $σ$ particle, even though no such particle is present in this calculation. I also show how these ingredients can describe the contact interaction that enters more modern descriptions of the internucleon interaction.

description: This paper considers the use of successive interference cancellation (SIC) to decode superposed signals in Long Range (LoRa) networks. We build over a known stochastic geometry model for LoRa networks and include the effect of recovering colliding packets through SIC. We derive closed-form expressions for the successful decoding of packets using SIC taking path loss, fading, noise, and interference into account, while we validate the model by means of Monte Carlo simulations. Results show that SIC-enabled LoRa networks improve worst-case reliability by up to 34%. We show that, for at least one test scenario, SIC increases by 159% the number of served users with the same worst-case reliability level.

description: We propose a novel resilient drone service composition framework for delivery in dynamic weather conditions. We use a skyline approach to select an optimal set of candidate drone services at the source node in a skyway network. Drone services are initially composed using a novel constraint-aware deterministic lookahead algorithm using the multi-armed bandit tree exploration. We propose a heuristic-based resilient service composition approach that adapts to runtime changes and periodically updates the composition to meet delivery expectations. Experimental results prove the efficiency of the proposed approach.

description: Some visual search tasks require to memorize the location of stimuli that have been previously scanned. Considerations about the eye movements raise the question of how we are able to maintain a coherent memory, despite the frequent drastically changes in the perception. In this article, we present a computational model that is able to anticipate the consequences of the eye movements on the visual perception in order to update a spatial memory
Production of heralded pure single photons from imperfect sources using cross phase modulation

description: Realistic single-photon sources do not generate single photons with certainty. Instead they produce statistical mixtures of photons in Fock states $\ket{1}$ and vacuum (noise). We describe how to eliminate the noise in the output of the sources by means of another noisy source or a coherent state and cross phase modulation (XPM). We present a scheme which announces the production of pure single photons and thus eliminates the vacuum contribution. This is done by verifying a XPM related phase shift with a Mach-Zehnder interferometer.
description: 8 pages, 8 EPS figures, RevTeX4. Following changes have been made in v.3: Title and abstract slightly changed; numerous minor revisions and clarifications within the text; an appendix with three new figures has been added. In version v4 we have included a supplementary analysis of our scheme that takes into account absorption losses. Our analysis is heuristic and based on a phenomenological model, which is independent of the physical realization of the proposed scheme. We have estimated upper bounds up to which absorption losses can be tolerated, so as our scheme to improve the efficiency of single photon sources still works. Accepted for publication in Phys. Rev.

Where are the ``Missing'' Galactic Baryons?
Creators: name: Sommer-Larsen, Jesper
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Based on 19 high-resolution N-body/gas-dynamical galaxy formation simulations in the LCDM cosmology it is shown, that for a galaxy like the Milky Way, in addition to the baryonic mass of the galaxy itself, about 70% extra baryonic mass should reside around the galaxy (inside of the virial radius), chiefly in the form of hot gas. Averaging over the entire field galaxy population, this ``external'' component amounts to 64-85% of the baryonic mass of the population itself. These results are supported by the recent detection of very extended, soft X-ray emission from the halo of the quiescent, massive disk galaxy NGC 5746. Some of the hot gas may, by thermal instability, have condensed into mainly pressure supported, warm clouds, similar to the Galactic High Velocity Clouds (HVCs). Based on an ultra-high resolution cosmological test simulation of a Milky Way like galaxy (with a gas particle mass and gravity softening length of only 7600 h^-1 Msun and 83 h^-1 pc,respectively), it is argued, that the hot gas phase dominates over the warm gas phase, in the halo. Finally, an origin of HVCs as ``leftovers'' from filamentary, ``cold'' accretion events, mainly occurring early in the history of galaxies, is proposed.

description: We introduce a relative index for a pair of dissipative operators in a von Neumann algebra of finite type and prove an analog of the Birman-Schwinger principle in this setting. As an application of this result, revisiting the Birman-Krein formula in the abstract scattering theory, we represent the de la Harpe-Skandalis determinant of the characteristic function of dissipative operators in the algebra in terms of the relative index.
title: Shifting ideas: work-family policy reform in Germany and England, 1997-2008
Creators: name: Mohun Himmelweit, Samuel
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2021

description: Since the late-1990s high income countries have taken an increasing interest in work-family policies, expanding provision of childcare and early education and reconfiguring maternity, paternity and parental leave policies to better facilitate reconciliation between employment and care responsibilities. These changes have occurred in contexts in which they represent a dramatic shift away from long-established ‘paths’ of policies towards families, underpinned by assumptions about the existence and desirability of male-breadwinner/female-caregiver family roles. This thesis investigates this expansion of work-family policies in two countries in which they represent such a shift: England and Germany. Unlike much of the comparative literature, which seeks to explain the cross-national trend of expansion, this thesis examines variation in reform and particularly why Germany underwent dramatic ‘path switching’ change compared to more moderate ‘path departure’ in England. Arguing that to understand the content of change, it is necessary to examine the ideas underpinning reform, the thesis compares the processes of reform in the two countries and the role of ideas therein. Through documentary analysis and interviews with participants in the policymaking process, it investigates how new ideas about work-family policy came onto the political agenda and how they influenced policy development. Drawing on a novel framework of ideational change, it concludes that in Germany deep ideational change took place, in which ‘background ideas’ that underpinned work-family policymaking were altered, while in England change remained at the level of problems and solutions and background ideas served to constrain change. The thesis explains this through differences in the form in which new ideas arrived on the political agenda, the political context which helped shape their reception and the way in which key political actors framed the new ideas.
