description: Clay minerals are ubiquitous in nature, and the manner in which they interact with their surroundings has important industrial and environmental implications. Consequently, a molecular-level understanding of the adsorption of molecules on clay surfaces is crucial. In this regard computer simulations play an important role, yet the accuracy of widely used empirical force fields (FF) and density functional theory (DFT) exchange-correlation functionals is often unclear in adsorption systems dominated by weak interactions. Herein we present results from quantum Monte Carlo (QMC) for water and methanol adsorption on the prototypical clay kaolinite. To the best of our knowledge, this is the first time QMC has been used to investigate adsorption at a complex, natural surface such as a clay. As well as being valuable in their own right, the QMC benchmarks obtained provide reference data against which the performance of cheaper DFT methods can be tested. Indeed using various DFT exchange-correlation functionals yields a very broad range of adsorption energies, and it is unclear a priori which evaluation is better. QMC reveals that in the systems considered here it is essential to account for van der Waals (vdW) dispersion forces since this alters both the absolute and relative adsorption energies of water and methanol. We show, via FF simulations, that incorrect relative energies can lead to significant changes in the interfacial densities of water and methanol solutions at the kaolinite interface. Despite the clear improvements offered by the vdW-corrected and the vdW-inclusive functionals, absolute adsorption energies are often overestimated, suggesting that the treatment of vdW forces in DFT is not yet a solved problem.

description: Venus Express provided a long-term monitoring of Venus atmosphere. Several works focused on the dynamics of the upper cloud visible on the day-side in ultraviolet images sensitive to the 65-70 km altitude and in the lower cloud level (50 km height) observable in the night-side of the planet in 1.74 microns. Here we use VIRTIS-M spectral images to study the upper cloud layer in ultraviolet (360-400 nm), visible (570-680 nm) and near infrared (900-955 nm) extending in time previous analysis of VIRTIS-M data. UV images show relatively well contrasted cloud features at the cloud top. Cloud features in the visible and near infrared images lie a few kilometers below the upper cloud top, have low contrast and are distinct to the features observed in the uv. Wind measurements were obtained over a six-year period using a semi-automatic cloud correlation algorithm. Results for the upper cloud confirm analysis based on images obtained by the Venus Monitoring Camera (Khatuntsev et al. 2013). At the cloud top the mean zonal and meridional winds vary with local time accelerating towards the local afternoon. The upper branch of the Hadley cell reaches maximum velocities at 45deg latitude and local times of 14-16h. The mean zonal winds in the uv cloud accelerated in the course of the 2006-2012 period 15 ms-1. The near infrared and visible images show a more constant circulation without time variability or longitudinal variations. The meridional circulation is absent in near infrared and visible images indicating thatthe Hadley-cell circulation in Venus atmosphere is shallow or the returning branch of the meridional circulation extends to levels below levels sensed in near infrared images. At the clod tops observed in UV images there are signatures of a long-term acceleration of the zonal winds when comparing winds from 2006-2008 to 2009-2012 with a mean acceleration of 17 ms-1 between both time periods

description: A hallmark of Weyl semimetal is the existence of surface Fermi arcs connecting two surface-projected Weyl nodes with opposite chiralities. An intriguing question is what determines the connectivity of surface Fermi arcs, when multiple pairs of Weyl nodes are present. To answer this question, we first show that the locations of surface Fermi arcs are predominantly determined by the condition that the Zak phase integrated along the normal direction to the surface is $π$. More importantly, the Zak phase can reveal the peculiar topological structure of Weyl semimetal directly in the bulk. Here, we show that the non-trivial winding of the Zak phase around each projected Weyl node manifests itself as a topological defect of the Wannier-Stark ladder, the energy eigenstates emerging under an electric field. Remarkably, this structure leads to "bulk Fermi arcs," i.e., open line segments in the bulk momentum spectra. It is argued that bulk Fermi arcs should exist in conjunction with the surface counterparts to conserve the Weyl fermion number under an electric field, which is supported by explicit numerical evidence.

description: We consider the gravitational force exerted on a point-like perturber of mass $M$ travelling within a uniform gaseous, opaque medium at constant velocity $V$. The perturber irradiates the surrounding gas with luminosity $L$. The diffusion of the heat released is modelled with a uniform thermal diffusivity $χ$. Using linear perturbation theory, we show that the force exerted by the perturbed gas on the perturber differs from the force without radiation (or standard dynamical friction). Hot, underdense gas trails the mass, which gives rise to a new force component, the heating force, with direction $+V$, thus opposed to the standard dynamical friction. In the limit of low Mach numbers, the heating force has expression $F_\mathrm{heat}=γ(γ-1)GML/(2χc_s^2)$, $c_s$ being the sound speed and $γ$ the ratio of specific heats. In the limit of large Mach numbers, $F_\mathrm{heat}=(γ-1)GML/(χV^2)f(r_\mathrm{min}V/4χ)$, where $f$ is a function that diverges logarithmically as $r_\mathrm{min}$ tends to zero. Remarkably, the force in the low Mach number limit does not depend on the velocity. The equilibrium speed, when it exists, is set by the cancellation of the standard dynamical friction and heating force. In the low Mach number limit, it scales with the luminosity to mass ratio of the perturber. Using the above results suggests that Mars- to Earth-sized planetary embryos heated by accretion in a gaseous protoplanetary disc should have eccentricities and inclinations that amount to a sizeable fraction of the disc's aspect ratio, for conditions thought to prevail at a few astronomical units.

description: One of the remaining challenges within the standard model is to gain a good understanding of QCD in the non-perturbative regime. A key step towards this aim is baryon spectroscopy, investigating the spectrum and the properties of baryon resonances. To gain access to resonances with small $πN$ partial width, photoproduction experiments provide essential information. Partial wave analyses need to be performed to extract the contributing resonances. Here, a complete experiment is required to unambiguously determine the contributing amplitudes. This involves the measurement of carefully chosen single and double polarisation observables. In a joint endeavour by MAMI, ELSA, and Jefferson Laboratory, a new generation of experiments with polarised beams, polarised proton and neutron targets, and $4π$ particle detectors have been performed in recent years. Many results of unprecedented quality were recently published by all three experiments, and included by the various partial wave analysis groups in their analyses, leading to substantial improvements, e.g. a more precise determination of resonance parameters. An overview of recent results is given, with an emphasis on results from the CBELSA/TAPS experiment, and their impact on our understanding of the nucleon excitation spectrum is discussed.

description: This paper investigates the link between the null controllability property for some abstract parabolic problems and an inequality that can be seen as a quantified Fattorini-Hautus test. Depending on the hypotheses made on the abstract setting considered we prove that this inequality either gives the exact minimal null control time or at least gives the qualitative property of existence of such a minimal time. We also prove that for many known examples of minimal time in the parabolic setting, this inequality recovers the value of this minimal time.

description: This report was commissioned in 2019 by the LSHTM Senior Leadership Team (now Executive Team) to conduct a time-limited piece of research on the School’s colonial history (1899-1960). LSHTM was set up as a colonial institution and benefitted from and contributed to British colonialism in a variety of ways between 1899 and 1960. It is largely to its role in British colonialism that the LSHTM owes its current power and position as a leader in health research and teaching.

First we provide a systematic recipe for translating from a Weinstein Lefschetz bifibration to a Legendrian handlebody. Then we present several applications of this technique to symplectic topology. This includes the detection of flexibility and rigidity for several families of Weinstein manifolds and the existence of closed exact Lagrangian submanifolds. In addition, we prove that the Koras--Russell cubic is Stein deformation equivalent to affine complex 3-space and verify the affine parts of the algebraic mirrors of two Weinstein 4-manifolds.

description: The aggressive update programme and continuous introduction of new generation of detec-tors and cameras across the Photon and Neutron (PaN) community have resulted in a rapid-ly rising awareness of data management problems across the data continuum of the large facilities. Today, facilities, synchrotrons and increasingly neutron facilities, are witnessing the arrival of big data experiments, that is, experiments that collect 10s of TBs of data within a few days of beam time. This has not only putting strain on the frontline “conventional” data services, e.g. data acquisition, storage and archiving, butalso motivate the facilities to im-prove its data management and support services across the entire data continuum, from proposals, experiment, data analysis to (data and paper) publications. This is to ensure that the description of the data, in the form of metadata, can be better captured in the first in-stance. And subsequently, they can be better exploited, during and immediately after the data are collected, but also over time when the data is analysed by the people who conduct the experiment and by others who need to exploit the data in other context, for example, for validation, secondary analysis, or meta-analysis. To do that, it is of interest to the facilities, the scientists, and the science communities in general, to keep track of the data, i.e. experiment, analysed, and resultant data, across the data continuum. That is the problem of provenance management for scientific data in the facility science domain. The aim of this deliverable is to assess the impact and value of provenance management in the PaN facilities in the PaNData-ODI project. It analyses the responses gathered from 11 operational large facilities in Europe regarding metadata capturing, storage, usage, and standardisation across the data continuum. Our survey has shown that there is still a long way to go in standardising metadata and metadata management across the data continuum within one facility and across different facilities. However, there are emerging efforts which aim at bridging the gap, including PaNKOS - an ontology for facility science, and ongoing work that leverages standardised metadata publishing and access protocol OAI-PMH to share metadata about experiment data. In particular, we show how PaNKOS can be used to encapsulate contextual metadata for experiment data and how it can be used to tag proposals to enhance the understanding of the science conducted in a facility.

description: We make an inventory of the interstellar medium material in three low-metallicity dwarf spheroidal galaxies of the Local Group (NGC147, NGC185 and NGC205). Ancillary HI, CO, Spitzer IRS spectra, Hα and X-ray observations are combined to trace the atomic, cold and warm molecular, ionised and hot gas phases. We present new Nobeyama CO(1-0) observations and Herschel SPIRE FTS [CI] observations of NGC205 to revise its molecular gas content. We derive total gas masses of M_gas = 1.9-5.5x10^5 Msun for NGC185 and M_gas = 8.6-25.0x10^5 Msun for NGC205. Non-detections combine to an upper limit on the gas mass of M_gas =< 0.3-2.2x10^5 Msun for NGC147. The observed gas reservoirs are significantly lower compared to the expected gas masses based on a simple closed-box model that accounts for the gas mass returned by planetary nebulae and supernovae. The gas-to-dust mass ratios GDR~37-107 and GDR~48-139 are also considerably lower compared to the expected GDR~370 and GDR~520 for the low metal abundances in NGC 185 (0.36 Zsun) and NGC205 (0.25 Zsun), respectively. To simultaneously account for the gas deficiency and low gas-to-dust ratios, we require an efficient removal of a large gas fraction and a longer dust survival time (~1.6 Gyr). We believe that efficient galactic winds (combined with heating of gas to sufficiently high temperatures in order for it to escape from the galaxy) and/or environmental interactions with neighbouring galaxies are responsible for the gas removal from NGC147, NGC185 and NGC205.

description: Finding obstacle-free paths in unknown environments is a big navigation issue for visually impaired people and autonomous robots. Previous works focus on obstacle avoidance, however they do not have a general view of the environment they are moving in. New devices based on computer vision systems can help impaired people to overcome the difficulties of navigating in unknown environments in safe conditions. In this work it is proposed a combination of sensors and algorithms that can lead to the building of a navigation system for visually impaired people. Based on traditional systems that use RGB-D cameras for obstacle avoidance, it is included and combined the information of a fish-eye camera, which will give a better understanding of the user's surroundings. The combination gives robustness and reliability to the system as well as a wide field of view that allows to obtain many information from the environment. This combination of sensors is inspired by human vision where the center of the retina (fovea) provides more accurate information than the periphery, where humans have a wider field of view. The proposed system is mounted on a wearable device that provides the obstacle-free zones of the scene, allowing the planning of trajectories for people guidance.
title: The philosophy of good.

Publisher: name: University of Kent

description: This Thesis discusses the nature of "good", as it exists and in its character as the goal of human action. I seek to show the integral relations of "good" within the world-order and its wider cosmological context. In the Introduction, I discuss the epistemological orientation of my approach and give an account of Husserl's epistemology. This leads to preliminary discussion of ontological structures of consciousness and description of the manifestation of "good" in "good-feeling". In Section 1, I describe the phenomena of good-feeling in their relations to the structures of consciousness and experience. In Section 2 . I give expositions of the works of Kant, Hegel and Sartre with respect to "good" and criticize phenomenologically. In Section 3 . I begin with an account of Scheler's theory of value and love, followed by criticism. This leads up to my presentation of my theory of "valour", using this term in a technical sense of my own adoption, meaning one's sense of personal value. This involves the "politics" and "pathology" of valour and its relations to mutual love, sexual attraction and, finally, morality. In the Conclusion, I firstly recapitulate my findings regarding "good" so far. Hollowing this, I present what in my view "a priori ontology" can establish concerning the being and nature of "good". In the final Appendix, I extend my discussion into what, epistemologically speaking, is the province of speculative metaphysics. Here I suggest and outline a world-view which expresses the changing relations of human beings and their "good" in relation to the wider context of the cosmos and its "good". This draws heavily on the works and insights of Rudolf Steiner. From his indications concerning social organization, I finally focus on proposing a concrete direction for the present human good.
The Healthy Ageing Questionnaire (HAQ) Index: Validation in the Singapore Longitudinal Ageing Study

description: Healthy ageing (HA) indices typically use full questionnaire, performance or blood-based assessment of functional ability which are time-consuming and resource-intensive. We developed and validated a simple and brief Healthy Ageing Questionnaire (HAQ) index with comparable measurement accuracy. Study Design and Setting: The 15-item HAQ (scored 0-100) was developed using data of 500 participants in the Singapore Study of Successful Ageing (SSOSA) a sub-cohort of the Singapore Longitudinal Ageing Study (SLAS2). Its construct, concurrent and predictive validity was evaluated in 2161 participants in the SLAS2 who were non-participants of the SSOSA. Results: The HAQ index (mean=64.0, SD=11.8) showed a coherent 3-factor structure (Cronbach’s alpha=0.735). HAQ scores were higher among participants who were female, highly educated, not living alone, non-smoking, non-alcohol drinkers, not at risk of malnutrition, were robust or pre-frail, not disabled, had no or <5 medical conditions, and no recent fall or hospitalization. It was positively correlated with MMSE and life satisfaction, and negatively correlated with age, logMAR vision, 5 times sit-and-stand, and timed-up-and-go. The HAQ index was significantly correlated but showed modest concordance with the Rowe-Kahn SA index. Increasing HAQ index quintiles were associated with increased mortality risks from 40.6 to 9.7 deaths per 1,000 p-y; covariate-adjusted hazard ratio for the highest Q5 levels (HAQ score >70) was 0.44 (95%CI=0.28-0.67). Using ROC analysis of predictive accuracy for survival, the AUC of HAQ was 0.675, and Rowe-Kahn SA index was 0.660 (p=0.361). Conclusion: The HAQ is a brief and accurate HA index that is potentially useful across diverse settings and purposes in research, healthcare and policy-making.
Bootstrapping Mixed Correlators in the Five Dimensional Critical O(N) Models

description: We use the conformal bootstrap approach to explore $5D$ CFTs with $O(N)$ global symmetry, which contain $N$ scalars $ϕ_i$ transforming as $O(N)$ vector. Specifically, we study multiple four-point correlators of the leading $O(N)$ vector $ϕ_i$ and the $O(N)$ singlet $σ$. The crossing symmetry of the four-point functions and the unitarity condition provide nontrivial constraints on the scaling dimensions ($Δ_ϕ$, $Δ_σ$) of $ϕ_i$ and $σ$. With reasonable assumptions on the gaps between scaling dimensions of $ϕ_i$ ($σ$) and the next $O(N)$ vector (singlet) scalar, we are able to isolate the scaling dimensions $(Δ_ϕ$, $Δ_σ)$ in small islands. In particular, for large $N=500$, the isolated region is highly consistent with the result obtained from large $N$ expansion. We also study the interacting $O(N)$ CFTs for $1\leqslant N\leqslant100$. Isolated regions on $(Δ_ϕ,Δ_σ)$ plane are obtained using conformal bootstrap program with lower order of derivatives $Λ$; however, they disappear after increasing $Λ$. We think these islands are corresponding to interacting but nonunitary $O(N)$ CFTs. Our results provide a lower bound on the critical value $N_c>100$, below which the interacting $O(N)$ CFTs turn into nonunitary. The critical value is unexpectedly large comparing with previous estimations.

description: In this work we present a novel approach for 3D layout recovery of indoor environments using a non-central acquisition system. From a non-central panorama, full and scaled 3D lines can be independently recovered by geometry reasoning without geometric nor scale assumptions. However, their sensitivity to noise and complex geometric modeling has led these panoramas being little investigated. Our new pipeline aims to extract the boundaries of the structural lines of an indoor environment with a neural network and exploit the properties of non-central projection systems in a new geometrical processing to recover an scaled 3D layout. The results of our experiments show that we improve state-of-the-art methods for layout reconstruction and line extraction in non-central projection systems. We completely solve the problem in Manhattan and Atlanta environments, handling occlusions and retrieving the metric scale of the room without extra measurements. As far as the authors knowledge goes, our approach is the first work using deep learning on non-central panoramas and recovering scaled layouts from single panoramas.

description: The increasing ability to collect data from urban environments, coupled with a push towards openness by governments, has resulted in the availability of numerous spatio-temporal data sets covering diverse aspects of a city. Discovering relationships between these data sets can produce new insights by enabling domain experts to not only test but also generate hypotheses. However, discovering these relationships is difficult. First, a relationship between two data sets may occur only at certain locations and/or time periods. Second, the sheer number and size of the data sets, coupled with the diverse spatial and temporal scales at which the data is available, presents computational challenges on all fronts, from indexing and querying to analyzing them. Finally, it is non-trivial to differentiate between meaningful and spurious relationships. To address these challenges, we propose Data Polygamy, a scalable topology-based framework that allows users to query for statistically significant relationships between spatio-temporal data sets. We have performed an experimental evaluation using over 300 spatial-temporal urban data sets which shows that our approach is scalable and effective at identifying interesting relationships.

description: We develop a manifest non-Hermitian approach of spectral and transport properties of two- dimensional mesoscopic systems in strong magnetic field. The finite system to which several ter- minals are attached constitutes an open system that can be described by an effective Hamiltonian. The life time of the quantum states expressed by the energy imaginary part depends specifically on the lead-system coupling and makes the difference among three regimes: resonant, integer quan- tum Hall effect and superradiant. The discussion is carried on in terms of edge state life time in different gaps, channel formation, role of hybridization, transmission coefficients quantization. A toy model helps in understanding non-Hermitian aspects in open systems.

description: The solar observatory Einstein Tower (Einsteinturm) at the Telegrafenberg in Potsdam is both a landmark of modern architecture and an important place for solar physics. Originally built for high-resolution spectroscopy and measuring the gravitational redshift, research shifted over the years to understanding the active Sun and its magnetic field. Nowadays, telescope and spectrographs are used for research and development, i.e., testing instruments and in particular polarization optics for advanced instrumentation deployed at major European and international astronomical and solar telescopes. In addition, the Einstein Tower is used for educating and training of the next generation astrophysicists as well as for education and public outreach activities directed at the general public. This article comments on the observatory's unique architecture and the challenges of maintaining and conserving the building. It describes in detail the characteristics of telescope, spectrographs, and imagers; it portrays some of the research and development activities.

description: Incorporation of sugar beet fibers in bakery products reduces the deficit in the intake of fiber and provides
 the improvement in the general condition of the body, due to the positive effects of fiber on physiological function
 and prevention of diseases of modern society (obesity, type 2 diabetes, cardiovascular disease, cancer). Because of
 the favorable balance of soluble and insoluble fiber and a small content of fat and sugar, extracted sugar beet
 cossettes are good raw material for the production of dietary fiber. However, to the fibers could be used in bakery
 must make their chemical modification in order to reduce the intensity of gray, unpleasant taste and odor. By
 treatment of sugar beet noodles with hydrogen peroxide at pH = 11, to obtain fibers which can be easily incorporated
 into the matrix of starch and gluten, in which there is minimal distortion of the structure. In this study was
 investigated the influence of drying temperature (55, 65 and 75°C) on the physico-chemical and microbiological
 characteristics of the modified fiber for application in bakery products. Total fiber content of samples is about 75%,
 soluble fiber 16% and insoluble 60%. A modified sugar beet fiber regardless of drying temperature has a highwater
 holding capacity (WHC) in the range of 1412 to 1736%, which prevents the release of bound water by the fiber and
 softening of dough during processing. Share of yellow color in samples is higher than the share of green color. The
 aw values of all sample, regardless of drying temperature, are under the limit value of 0.6, which confirmed the
 microbiological quality of the tested fibers and makes them suitable for application in bakery products.

OmniSCV: An Omnidirectional Synthetic Image Generator for Computer Vision

description: Omnidirectional and 360° images are becoming widespread in industry and in consumer society, causing omnidirectional computer vision to gain attention. Their wide field of view allows the gathering of a great amount of information about the environment from only an image. However, the distortion of these images requires the development of specific algorithms for their treatment and interpretation. Moreover, a high number of images is essential for the correct training of computer vision algorithms based on learning. In this paper, we present a tool for generating datasets of omnidirectional images with semantic and depth information. These images are synthesized from a set of captures that are acquired in a realistic virtual environment for Unreal Engine 4 through an interface plugin. We gather a variety of well-known projection models such as equirectangular and cylindrical panoramas, different fish-eye lenses, catadioptric systems, and empiric models. Furthermore, we include in our tool photorealistic non-central-projection systems as non-central panoramas and non-central catadioptric systems. As far as we know, this is the first reported tool for generating photorealistic non-central images in the literature. Moreover, since the omnidirectional images are made virtually, we provide pixel-wise information about semantics and depth as well as perfect knowledge of the calibration parameters of the cameras. This allows the creation of ground-truth information with pixel precision for training learning algorithms and testing 3D vision approaches. To validate the proposed tool, different computer vision algorithms are tested as line extractions from dioptric and catadioptric central images, 3D Layout recovery and SLAM using equirectangular panoramas, and 3D reconstruction from non-central panoramas.

$N-$body dynamics of Intermediate mass-ratio inspirals in globular clusters

description: The intermediate mass-ratio inspiral of a stellar compact remnant into an intermediate mass black hole (IMBH) can produce a gravitational wave (GW) signal that is potentially detectable by current ground-based GW detectors (e.g., Advanced LIGO) as well as by planned space-based interferometers (e.g., eLISA). Here, we present results from a direct integration of the post-Newtonian $N$-body equations of motion describing stellar clusters containing an IMBH and a population of stellar-mass black holes (BHs) and solar mass stars. We take particular care to simulate the dynamics closest to the IMBH, including post-Newtonian effects up to order $2.5$. Our simulations show that the IMBH readily forms a binary with a BH companion. This binary is gradually hardened by transient 3-body or 4-body encounters, leading to frequent substitutions of the BH companion, while the binary's eccentricity experiences large amplitude oscillations due to the Lidov-Kozai resonance. We also demonstrate suppression of these resonances by the relativistic precession of the binary orbit. We find an intermediate mass-ratio inspiral in one of the 12 cluster models we evolved for $\sim 100$ Myr. This cluster hosts a $100 M_\odot$ IMBH embedded in a population of 32 $10M_\odot$ BH and 32,000 $1M_\odot$ stars. At the end of the simulation, after $\sim 100$ Myr of evolution, the IMBH merges with a BH companion. The IMBH--BH binary inspiral starts in the eLISA frequency window ($\gtrsim 1\rm mHz$) when the binary reaches an eccentricity $1-e\simeq 10^{-3}$. After $\simeq 10^5$ years the binary moves into the LIGO frequency band with a negligible eccentricity. We comment on the implications for GW searches, with a possible detection within the next decade.

description: We present a multi-wavelength temporal analysis of the blazar 3C 454.3 during the high $γ$-ray active period from May-December, 2014. Except for X-rays, the period is well sampled at near-infrared (NIR)-optical by the \emph{SMARTS} facility and the source is detected continuously on daily timescale in the \emph{Fermi}-LAT $γ$-ray band. The source exhibits diverse levels of variability with many flaring/active states in the continuously sampled $γ$-ray light curve which are also reflected in the NIR-optical light curves and the sparsely sampled X-ray light curve by the \emph{Swift}-XRT. Multi-band correlation analysis of this continuous segment during different activity periods shows a change of state from no lags between IR and $γ$-ray, optical and $γ$-ray, and IR and optical to a state where $γ$-ray lags the IR/optical by $\sim$3 days. The results are consistent with the previous studies of the same during various $γ$-ray flaring and active episodes of the source. This consistency, in turn, suggests an extended localized emission region with almost similar conditions during various $γ$-ray activity states. On the other hand, the delay of $γ$-ray with respect to IR/optical and a trend similar to IR/optical in X-rays along with strong broadband correlations favor magnetic field related origin with X-ray and $γ$-ray being inverse Comptonized of IR/optical photons and external radiation field, respectively.

description: We study polarization squeezing of a light beam initially in the coherent state using the nonlinear interaction hamiltonian $ H=k\big(\hat a_{x}^{\dagger2}+{\hat a_{x}}^2\big)$. For the degree of polarization squeezing, we use a definition written in the final form by the authors and also used in earlier papers. We find that the polarization squeezing can be very high and the degree of polarization squeezing can be less than unity by a very small amount. We achieve the polarization squeezing even for very low beam intensity under some conditions involving phase angles in the polarization modes.
