description: Surprisingly strong CO emission has been observed from more than a dozen debris disks around nearby main-sequence stars. The origin of this CO is unclear, in particular whether it is left over from the protoplanetary disk phase or is second-generation material released from collisions between icy bodies like debris dust. The primary unexplored avenue for distinguishing the origin of the material is understanding its molecular composition. Here we present a deep search for five molecules (CN, HCN, HCO+, SiO, and CH3OH) in the debris disk around 49 Ceti. We take advantage of the high sensitivity of the Atacama Large Millimeter/submillimeter Array (ALMA) at Band 7 to integrate for 3.2 hours at modest spatial (1") and spectral (0.8 km/s) resolution. Our search yields stringent upper limits on the flux of all surveyed molecular lines, which imply abundances relative to CO that are orders of magnitude lower than those observed in protoplanetary disks and Solar System comets, and also those predicted in outgassing models of second-generation material. However, if CI shielding is responsible for extending the lifetime of any CO produced in second-generation collisions, as proposed by Kral et al. (2018), then the line ratios do not reflect true ice phase chemical abundances, but rather imply that CO is shielded by its own photodissociation product, CI, but other molecules are rapidly photodissociated by the stellar and interstellar radiation field.

description: Most tests of general relativity with gravitational-wave observations rely on inferring the degree to which a signal deviates from general relativity in conjunction with the astrophysical parameters of its source, such as the component masses and spins of a compact binary. Due to features of the signal, measurements of these deviations are often highly correlated with the properties of astrophysical sources. As a consequence, prior assumptions about astrophysical parameters will generally affect the inferred magnitude of the deviations. Incorporating information about the underlying astrophysical population is necessary to avoid biases in the inference of deviations from general relativity. Current tests assume that the astrophysical population follows an unrealistic fiducial prior chosen to ease sampling of the posterior -- for example, a prior flat in component masses -- which is is inconsistent with both astrophysical expectations and the distribution inferred from observations. We propose a framework for fortifying tests of general relativity by simultaneously inferring the astrophysical population using a catalog of detections. Although this method applies broadly, we demonstrate it concretely on massive graviton constraints and parameterized tests of deviations to the post-Newtonian phase coefficients. Using observations from LIGO-Virgo-KAGRA's third observing run, we show that concurrent inference of the astrophysical distribution strengthens constraints and improves overall consistency with general relativity. We provide updated constraints on deviations from the theory, finding that, upon modeling the astrophysical population, the 90\%-credible upper limit on the mass of the graviton improves by $25\%$ to $m_g \leq 9.6 \times 10^{-24}\, \mathrm{eV}/c^2$ and the inferred population-level post-Newtonian deviations move ${\sim} 0.4 σ$ closer to zero.

The kinetics of Ca²⁺ transport and (Ca²⁺ + Mg²⁺)-ATPase activity in human erythrocyte inside-out vesicles
Creators: name: Akyempon, Christian Kweku
Publisher: name: University of British Columbia
Year: 2010

description: The kinetics and the stoichiometry of the Ca²⁺ pump in human erythrocytes was investigated using inside-out vesicles as a model. Inside-out vesicles were prepared by a modified procedure of Steck and Kant (12) outlined by Quist and Roufogalis(9), Since calmodulin has been shown to regulate the activites of the (Ca²⁺ + Mg²⁺)-ATPase, and the Ca²⁺ transport system (49, 50), its effect on the kinetics and stoichiometry was also investigated in inside-out vesicles treated with EDTA to remove endogeneous calmodulin (78). The calmodulin used in this study was purified from human erythrocytes. The stoichiometry of the Ca²⁺ pump was found to vary with intracellular Ca²⁺ concentration: in a low Ca²⁺ concentration range of 0.71 μM to 24 μM, it was estimated to be close to 2 whereas in the high Ca²⁺ range -50 μM to 300 μM, it was estimated to be close to 1. Calmodulin, ATP concentrations from 0.1 - 3 mM and Mg²⁺ concentrations of 3 mM and above did not alter the stoichiometry while a stoichiometry of 2 was obtained at 1 mM Mg²⁺ concentration at all Ca²⁺ concentrations studied. A model for Ca²⁺ efflux is suggested to explain these results. Calmodulin was found to increase the V[sub max] and the affinity of the (Ca²⁺+ Mg²⁺)-ATPase for Ca²⁺. The high affinity component was found to have a K[sub diss] (K[sub l]) of 2 to 4 μM Ca²⁺ whereas the low Ca²⁺ affinity component was found to have a K[sub diss] of 200 t0 300 μM Ca²⁺ Lowering Mg²⁺concentrations in the presence of calmodulin resulted in the predominance of the high affinity component of the Ca²⁺ - transport system which was inhibited at high Ca²⁺ concentrations. Competition between Ca²⁺ and Mg²⁺ for an inhibitory site located on the high affinity form, E[sub l]P of (Ca²⁺ + Mg²⁺ )-ATPase enzyme is suggested to account for the Ca²⁺ inhibition observed at low Mg²⁺ concentrations.

description: Ethylene is the simplest of the organic compounds known as alkenes, which contain carbon-carbon double bonds. It is a colourless, flammable gas having a sweet taste and odour. Ethylene is an important industrial organic chemical. It is produced by heating either natural gas, especially its ethane and propane components. Ethylene use falls into two main categories: as a monomer, from which longer carbon chains are constructed, and as a starting material for other two-carbon compounds. The first of these is the single largest use of ethylene, consuming about one-half of the annual output. Polymerization (the repetitive joining of many small molecules into larger ones) of ethylene gives polyethylene, a polymer having many uses, particularly in the production of packaging films, wire coatings, and squeeze bottles. When polymerization is carried out at high pressures and temperatures, the product is called low-density polyethylene and has properties different from the high-density polyethylene formed by polymerization under Ziegler-Natta catalytic conditions. Another use of ethylene as a monomer is in the formation of linear α-olefins. The oligomerization catalysts are similar to the Ziegler-Natta polymerization catalysts. Linear α-olefins have a number of applications, including the preparation of linear low-density polyethylene.

description: We develop a stochastic calculus for processes which are built by convoluting a pure jump, zero expectation Lévy process with a Volterra-type kernel. This class of processes contains, for example, fractional Lévy processes as studied by Marquardt [Bernoulli 12 (2006) 1090--1126.] The integral which we introduce is a Skorokhod integral. Nonetheless, we avoid the technicalities from Malliavin calculus and white noise analysis and give an elementary definition based on expectations under change of measure. As a main result, we derive an Itô formula which separates the different contributions from the memory due to the convolution and from the jumps.

description: Tomato (Solanum lycopersicum) is a popular fruit, grown worldwide for its culinary usages in fresh, processed and cooked foods. Additionally, consumption of tomato fruit is associated with health benefits due to their functional food properties. The signature hedonic measures of tomato fruits are their flavour, aroma and colour, which function as drivers of consumer perception of quality and are therefore associated with purchasing habits. Accordingly, there is interest in strategies to enhance these hedonic measures through supplementation of fertiliser regimens with biostimulants, which have demonstrated improvements to hedonic measures of other food crops. Herein, tomatoes were grown hydroponically with and without supplementation of a biostimulant complex (BC) comprising molasses, Aloe vera extract and fish-hydrolysate. Results identified significant increases in flower and fruit count (1.68-fold, p = 0.033), improvements to the hedonic measures of overall mouthfeel (p = 0.022) and overall visual assessment (p = 0.005), however decreased flavonoid content (0.61-fold, p = 0.022). Accordingly, supplementation of tomato growth with BC was associated with enhancements to the quantity and hedonic quality of tomato at the cost of functional food quality. These findings support the utilisation of biostimulants to enhance food goods’ cultivation and quality perception.

THE IMPACT OF ACOUSTICS ON THE DESIGN OF A VIBRANT CULTURAL CENTRE IN YENAGOA, BAYELSA STATE

Publisher: name: AYDEN JOURNAL
Year: 2024
Subjects: Acoustics, Culture, Cultural Centre, Sound

description: Cultural centres are venues or institutions dedicated to promoting and preserving the culture of a particular region, community or group of people. In this present era where almost everyone and everything is nearly taken over by technology, the cultural identity of the nation is gradually perishing. Cultural centres offer a wide range of activities relating to the arts and traditions of the people they represent and play a crucial role in fostering the understanding and appreciation of cultural heritage and diversity. In many states where diverse ethnic groups exist, like Bayelsa State for example, Cultural centres serve as focal points for people of the different ethnic groups, both within and outside the state, to promote cross-cultural understanding and social interactions. Bayelsa State lies in the heart of the Niger Delta in the Southern part of Nigeria and it is a home of a variety of cultures that reflect the history, beliefs, values and traditions of the different ethnic groups in the State. The existence of Cultural centres is essential in order to safeguard the customs and traditions of the people. The influence of acoustics in moulding the tourist experience is an aspect that is often overlooked or neglected in the design of these cultural centres. This research addresses the significance of acoustics in various spaces within the cultural centre, from performance halls and exhibition areas to communal gathering spaces. It explores the effective application of acoustic principles within the facility to create an immersive and engaging environment for the people and discusses how the design of the spaces in the facility, materials used for the construction, soundproofing techniques and acoustic treatments can enhance the quality of auditory experiences. Through qualitative and quantitative research methods, such as case studies and survey, the study explores several acoustics inclined construction materials and how it is integrated in the design of. Cultural Centre. Since technology has been constantly evolving and improving with time, new techniques of utilising it as a tool for improving architectural acoustics have begun to emerge. The effective application of acoustics in cultural centres serves to create a sound ambience where cultural expressions are celebrated, and the rich tapestry of traditions is woven into the fabric of the experience of all who visit.
On the robustness of H-deficient post-AGB tracks

Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: We analyze the robustness of H--deficient post--AGB tracks regarding previous evolution of their progenitor stars and the constitutive physics of the remnants. Our motivation is a recent suggestion of Werner & Herwig (2006) that previous evolution should be important in shaping the final post--AGB track and the persisting discrepancy between asteroseismological and spectroscopical mass determinations. This work is thus complementary to our previous work (Miller Bertolami & Althaus 2006) and intends to shed some light on the uncertainty behind the evolutionary tracks presented there. We compute full evolutionary models for PG1159 stars taking into account different extramixing (overshooting) efficiencies and lifetimes on the TP-AGB during the progenitor evolution. We also assess the effect of possible differences in the opacities and equation of state by artificially changing them before the PG1159 stage. Also comparisons are made with the few H-deficient post--AGB tracks available in the literature. Contrary to our expectations, we found that previous evolution is not a main factor in shaping H--deficient post--AGB tracks. Interestingly enough, we find that only an increase of $\sim50%$ in the intershell opacities at high effective temperatures may affect the tracks as to reconcile spectroscopic and asteroseismologic mass determinations. This forces us to conclude that our previous tracks (Miller Bertolami & Althaus 2006) are robust enough as to be used for spectroscopic mass determinations, unless opacities in the intershell region are substantially different. Our results, then, call for an analysis of possible systematics in the usually adopted asteroseismological mass determination methods.

Models for gamma-ray production in low-mass microquasars

Subjects: subject: Astrophysics (astro-ph)

description: Unlike high-mass gamma-ray binaries, low-mass microquasars lack external sources of radiation and matter that could produce high-energy emission through interactions with relativistic particles. In this work we consider the synchrotron emission of protons and leptons that populate the jet of a low-mass microquasar. In our model photohadronic and inverse Compton (IC) interactions with synchrotron photons produced by both protons and leptons result in a high-energy tail of the spectrum. We also estimate the contribution from secondary pairs injected through photopair production. The high-energy emission is dominated by radiation of hadronic origin, so we can call these objects proton microquasars.

The born again (VLTP) scenario revisited: The mass of the remnants and implications for V4334 Sgr

description: We present 1-D numerical simulations of the very late thermal pulse (VLTP) scenario for a wide range of remnant masses. We show that by taking into account the different possible remnant masses, the observed evolution of V4334 Sgr (a.k.a. Sakurai's Object) can be reproduced within the standard 1D-MLT stellar evolutionary models without the inclusion of any $ad-hoc$ reduced mixing efficiency. Our simulations hint at a consistent picture with present observations of V4334 Sgr. From energetics, and within the standard MLT approach, we show that low mass remnants \hbox{($M\lesssim0.6$\msun)} are expected to behave markedly different than higher mass remnants \hbox{($M\gtrsim0.6$\msun)} in the sense that the latter are not expected to expand significantly as a result of the violent H-burning that takes place during the VLTP. We also assess the discrepancy in the born again times obtained by different authors by comparing the energy that can be liberated by H-burning during the VLTP event.

description: Van der Waals magnetic materials are an ideal platform to study low-dimensional magnetism. Opposed to other members of this family, the magnetic semiconductor CrSBr is highly resistant to degradation in air, which, besides its exceptional optical, electronic, and magnetic properties, is the reason the compound is receiving considerable attention at the moment. For many years, its magnetic phase diagram seemed to be well-understood. Recently, however, several groups observed a magnetic transition in magnetometry measurements at temperatures of around 40 K that is not expected from theoretical considerations, causing a debate about the intrinsic magnetic properties of the material. In this letter, we report the absence of this particular transition in magnetization measurements conducted on high-quality CrSBr crystals, attesting to the extrinsic nature of the low-temperature magnetic phase observed in other works. Our magnetometry results obtained from large bulk crystals are in very good agreement with the magnetic phase diagram of CrSBr previously predicted by the mean-field theory; A-type antiferromagnetic order is the only phase observed below the Néel temperature at TN = 131 K. Moreover, numerical fits based on the Curie-Weiss law confirm that strong ferromagnetic correlations are present within individual layers even at temperatures much larger than TN.

The preprint is available upon request from the authors. For clarity, consistence of language and conciseness, we discuss the origin and conditions of the validity of Zipf's law using the terminology of firms' asset values. We use firms at the entities whose size distributions are to be explained. It should be noted, however, that most of the relations discussed in this book, especially the intimate connection between Zipf's and Gilbrat's laws, underlie Zipf's law in diverse scientific areas. The same models and variations thereof can be straightforwardly applied to any of the other domains of application.

In this work, the monolayer $\mathrm{GdCl_2}$ is proposed as a potential candidate material for valleytronic applications by the first-principles calculations. It is proved that monolayer $\mathrm{GdCl_2}$ is a FM semiconductor with the easy axis along out of plane direction and strong FM coupling. A spontaneous valley polarization with a valley splitting of 42.3 meV is produced due to its intrinsic ferromagnetism and spin orbital coupling (SOC). Although the VBM of unstrained monolayer $\mathrm{GdCl_2}$ is away from valley points, a very small compressive strain (about 1\%) can make VBM move to valley points. We propose a possible way to realize anomalous valley Hall effect in monolayer $\mathrm{GdCl_2}$ by piezoelectric effect, not an external electric field, namely piezoelectric anomalous valley Hall effect (PAVHE). This phenomenon could be classified as piezo-valleytronics, being similar to piezotronics and piezophototronics. The only independent piezoelectric strain coefficient $d_{11}$ is -2.708 pm/V, which is comparable to one of classical bulk piezoelectric material $α$-quartz ($d_{11}$=2.3 pm/V). The biaxial in-plane strain and electronic correlation effects are considered to confirm the reliability of our results. Finally, the monolayer $\mathrm{GdF_2}$ is predicted to be a ferrovalley material with dynamic and mechanical stabilities, PMA, VBM at valley points, strong FM coupling, valley splitting of 47.6 meV, and $d_{11}$ of 0.584 pm/V.

description: It is shown that above the temperature of maximum abundance, recombination rates into the excited states of He-like ions that are calculated using earlier, more approximate methods differ markedly from rates obtained from recent distorted-wave and R-Matrix calculations (unified recombination rate coefficients) for Ca, Fe, and Ni. The present rates lead to G ratios that are greatly lower than those resulting from the more approximate rates in previous works, by up to a factor of six at high electron temperatures. Excellent agreement between the distorted-wave and the R-Matrix rates, as well as excellent agreement in the G ratios calculated from them, provides support for the accuracy of these new values which have a broad applicability to the modelling and interpreting of X-ray spectra from a variety of astrophysical and laboratory sources.

title: Administrative reforms in pluralistic societies : the case of Lebanon.
Creators: name: Jamali, Dima
Publisher: name: University of Kent
Year: 2021

description: This dissertation examines the processes and dynamics of administrative reform in the Lebanese multi-confessional context. It explores whether these processes exhibit special features or characteristics and the extent to which they are conditioned by the realities of the Lebanese pluralistic environment. The orientation in this thesis is indeed consistent with recent writings in the administrative reform literature, which emphasize the contextual distinctiveness of administration and reform in each country and the need to account for embedded contextual differences. The research thus attempts to place Lebanese administrative reform in a specific historical, cultural, and political frame of reference and link it to the realities of pluralism and sectarian politics in Lebanon. Further, the research undertakes an in-depth case study examination of two adrninistrtive ectocs (tee a&3 ad &i g greater insight into post-war Lebanese reform patterns and dynamics. The research highlights the complexity of administrative reform and the fact that reform endeavors are invariably conditioned by a multitude of embedded and contingent factors, cultural, political and economic. The research also suggests the potential influence of the regional and international environments on country-specific programs of planned change. Indeed, the research suggests that the complex inter-relationships of these various factors and their specific constellations in specific periods can exert a significant influence on the course and fate of reform initiatives and help account for the specific reform trajectories observed in Lebanon before and after the war

description: The dynamics in mergers of binary neutron star (BNS) systems depend sensitively on the equation of state (EOS) of dense matter. This has profound implications on the emission of gravitational waves (GWs) and the ejection of matter in the merger and post-merger phases and is thus of high interest for multi-messenger astronomy. Today, a variety of nuclear EOSs are available with various underlying microphysical models. This calls for a study to focus on EOS effects from different physical nuclear matter properties and their influence on BNS mergers. We perform simulations of equal-mass BNS mergers with a set of 9 different EOSs based on Skyrme density functionals. In the models, we systematically vary the effective nucleon mass, incompressibility, and symmetry energy at saturation density. This allows us to investigate the influence of specific nuclear matter properties on the dynamics of BNS mergers. We analyze the impact of these properties on the merger dynamics, the fate of the remnant, disk formation, ejection of matter, and gravitational wave emission. Our results indicate that some aspects of the merger are sensitive to the EOS around saturation density while others are sensitive to the behavior towards higher densities, e.g., characterized by the slope of the pressure as a function of density. The detailed density dependence of the EOS thus needs to be taken into account to describe its influence on BNS mergers.

Limits on the Mass and Initial Entropy of 51 Eri b from Gaia EDR3 Astrometry

description: 51 Eri b is one of the only young planets consistent with a wide range of possible initial entropy states, including the cold-start scenario associated with some models of planet formation by core accretion. The most direct way to constrain the initial entropy of a planet is by measuring its luminosity and mass at a sufficiently young age that the initial conditions still matter. We present the tightest upper limit on 51 Eri b's mass yet (M < 11 Mjup at 2$σ$) using a cross-calibration of Hipparcos and Gaia EDR3 astrometry and the orbit-fitting code orvara. We also reassess its luminosity using a direct, photometric approach, finding log(Lbol/Lsun) = -5.5$\pm$0.2 dex. Combining this luminosity with the 24$\pm$3 Myr age of the $β$ Pic moving group, of which 51 Eri is a member, we derive mass distributions from a grid of evolutionary models that spans a wide range of initial entropies. We find that 51 Eri b is inconsistent with the coldest-start scenarios, requiring an initial entropy of >8 $k_B$/baryon at 97% confidence. This result represents the first observational constraint on the initial entropy of a potentially cold-start planet, and it continues the trend of dynamical masses for directly imaged planets pointing to warm- or hot-start formation scenarios.

Cooperative optical pattern formation in an ultrathin atomic layer

description: Spontaneous pattern formation from a uniform state is a widely studied nonlinear optical phenomenon that shares similarities with non-equilibrium pattern formation in other scientific domains. Here we show how a single layer of atoms in an array can undergo nonlinear amplification of fluctuations, leading to the formation of intricate optical patterns. The origin of the patterns is intrinsically cooperative, eliminating the necessity of mirrors or cavities, although introduction of a mirror in the vicinity of the atoms significantly modifies the scattering profiles. The emergence of these optical patterns is tied to a bistable collective response, which can be qualitatively described by a long-wavelength approximation, similar to a nonlinear Schrödinger equation of optical Kerr media or ring cavities. These collective excitations have the ability to form singular defects and unveil atomic position fluctuations through wave-like distortions.

description: Causal soliton formation (e.g. oscillons, Q-balls) in the primordial Universe is expected to give rise to a universal gravitational wave (GW) background, at frequencies smaller than scales of nonlinearity. We show that modifications of the soliton density field, driven by soliton interactions or initial conditions, can significantly enhance universal GWs. Gravitational clustering of solitons naturally leads to generation of correlations in the large-scale soliton density field. As we demonstrate for axion-like particle (ALP) oscillons, the growing power spectrum amplifies universal GW signals, opening new avenues for probing the physics of the early Universe with upcoming GW experiments. Our results are applicable to variety of scenarios, such as solitons interacting through a long range Yukawa-like fifth force.

description: Using hydrodynamical $N$-body simulations, we show that the observed structure and kinematics of the extremely metal-poor, dwarf irregular galaxy DDO 68 is compatible with a merger event with at least two smaller satellite galaxies. We were able to obtain a self-consistent model that simultaneously reproduces several of its observed features, including: the very asymmetric and disturbed shape of the stellar component, the overall HI distribution and its velocity field, the arc-like stellar structure to the west, the low-surface brightness stellar stream to the north. The model implies the interaction of the main progenitor of DDO 68 with two systems with dynamical masses $7\times10^8\,M_{\odot}$ and almost $10^8\,M_{\odot}$ -- 1/20 and 1/150 times the dynamical mass of DDO 68, respectively. We show that the merger between DDO 68 and the most massive of its satellites offers a route to explain the large offset of DDO 68 from the mass-metallicity relation. Assuming that the interacting galaxies have metallicities prior to the merger compatible with those of galaxies with similar stellar masses, we provide quantitative evidence that gas mixing alone does not suffice at diluting the gas of the two components; according to our simulations, the HII regions observed along the Cometary Tail trace the low metallicity of the accreted satellite rather than that of DDO 68's main body. In this case, the mass corresponding to the low metallicity is that of the secondary body and DDO 68 becomes consistent with the mass-metallicity relation.
