description: Although the majority of radial velocity detected planets have been found orbiting solar-type stars, a fraction of them have been discovered around giant stars. These planetary systems have revealed different orbital properties when compared to solar-type stars companions. In particular, radial velocity surveys have shown that there is a lack of giant planets in close-in orbits around giant stars, in contrast to the known population of hot-Jupiters orbiting solar-type stars. The reason of this distinctive feature in the semimajor-axis distribution has been theorized to be the result of the stellar evolution and/or due to the effect of a different formation/evolution scenario for planets around intermediate-mass stars. However, in the past few years, a handful of transiting short-period planets (P$\lesssim$ 10 days) have been found around giant stars, thanks to the high precision photometric data obtained initially by the Kepler mission, and later by its two-wheels extension K2. These new discoveries, have allowed us for the first time to study the orbital properties and physical parameters of these intriguing and elusive sub-stellar companions. In this paper we report on an independent discovery of a transiting planet in field 10 of the K2 mission, also reported recently by Grunblatt et al. (2017). The main orbital parameters of EPIC\,228754001\,$b$, obtained with all the available data for the system, are the following: $P$ = 9.1708 $\pm$ 0.0025 $d$, $e$ = 0.290 $\pm$ 0.049, Mp = 0.495 $\pm$ 0.007 Mjup \,and Rp = 1.089 $\pm$ 0.006 Rjup. This is the fifth known planet orbiting any giant star with $a < 0.1$, and the most eccentric one among them, making EPIC\,228754001\,$b$ a very interesting object.

description: Metal contamination in drinking water, especially heavy metals such as lead, and corrosion issues, pose a threat to human health and have received increasing attention in recent years. This study reports on the results of ‘The Massachusetts Assistance Program for Lead in School Drinking Water’ and provides a better understanding of the dynamics of sampling protocols, premise plumbing and their influence on lead and copper concentrations. ‘The Massachusetts Assistance Program for Lead in School Drinking Water’ that was announced in April 2016, implemented tap-based water sampling for lead and copper at K-12 public schools and Early Education and Childcare centers in Massachusetts, thus targeting the most vulnerable populations to the health risks of lead and copper exposure. The Program funded by the Massachusetts Department of Environmental Protection (MassDEP) and implemented by both UMass Amherst and MassDEP, saw the collection and testing of about 68,000 water samples across 992 school buildings between June 2016 and December 2018. About 44% of school buildings had one or more samples exceeding the lead AL, 9% of school buildings had one or more samples exceeding the copper AL, and another 29% had exceedances of both the lead and copper ALs. Flushing was found to have a higher impact in decreasing lead concentrations as compared to the impact on copper concentrations. A decrease in lead concentration levels is seen in schools constructed later than the year 1990, possibly indicating the implementation of lead materials control following the regulations in the 1980s and the LCR.

description: We obtained Halpha diffraction limited data of the LBV star P Cyg using the ONERA Adaptive Optics (AO) facility BOA at the OHP 1.52m telescope on October 1997. Taking P Cyg and the reference star 59 Cyg AO long exposures we find that P Cyg clearly exhibits a large and diffuse intensity distribution compared to the 59 Cyg's point-like source. A deconvolution of P Cyg using 59 Cyg as the Point Spread Function was performed by means of the Richardson-Lucy algorithm. P Cyg clearly appears as an unresolved star surrounded by a clumped envelope. The reconstructed image of P Cyg is compared to similar spatial resolution maps obtained from radio aperture synthesis imaging. We put independent constraints on the physics of P Cyg which agree well with radio results. We discuss future possibilities to constrain the wind structure of P Cyg by using multi-resolution imaging, coronagraphy and long baseline interferometry to trace back its evolutionary status.

description: We use the Bosnian Living Standards Measurement Study (LSMS) survey to show that conflict-induced displacement of agricultural households dramatically affects the adoption of new technologies in agriculture. We exploit the heterogeneity in the level of violence in the pre-war location to account for selection bias. This natural experiment seems to be a source of exogenous variation in our case because violence aims at ethnic cleansing, without economic consideration. We find that the displaced are less likely than stayers to adopt fertiliser and pesticide.

description: Using renormalization-group techniques we analyze equilibrium properties of a large gated quantum dot coupled via a long and narrow channel to a reservoir of electrons. Treating the electrons in the channel as one-dimensional and interacting, we demonstrate that for nearly-open dot and not very strong spin fluctuations the ground-state properties as a function of the gate voltage are non-analytic at the points of half-integer average dot population. Specifically, the exact result of K. A. Matveev, Phys. Rev. B 51, 1743 (1995), that the dot capacitance shows periodic logarithmic singularities is rederived as a special case corresponding to non-interacting electrons. We demonstrate that this conclusion also holds in the presence of SU(2) spin symmetry, and argue that logarithmic singularities persist as long as the Coulomb blockade is destroyed which will be the case for sufficiently large tunneling and not very strong interparticle repulsions. We show that interparticle repulsions aid the Coulomb blockade to survive disordering effect of zero-point motion provided the tunneling is sufficiently weak. Upon increase of tunneling, the Coulomb blockade disappears through a Kosterlitz-Thouless phase transition characterized by a dot population jump whose magnitude is only determined by interparticle repulsions in the channel. Similar conclusions are applicable to systems without SU(2) spin symmetry except that the logarithmic singularity of the capacitance is replaced by a power-law non-analyticity whose exponent characterizes the degree of spin fluctuations.

title: The predictive utility of the theory of planned behaviour for physical activity in a Malaysian population: A mixed methods approach
Creators: name: Ng, KB
Publisher: name: Liverpool John Moores University
Year: 2021

description: Participation in physical activity is a key component of a healthy lifestyle. The objectives of this dissertation were to test the utility of predicting physical activity behaviour of the Theory of Planned Behaviour (TPB) as well as self-efficacy using a specifically devised questionnaire for a Malaysian population and the Exercise Self-Efficacy Scale. This study was carried out among the Non-Governmental Organizations (NGO) receiving support from the Ministry of Health Malaysia to run physical activity programmes. To fulfil the objectives, both quantitative and qualitative methods were employed in this research. The first study used qualitative methods to develop a Malaysian TPB questionnaire. This was then used in the main study where quantitative data were collected at four time points in a longitudinal study of engagement with physical activity programmes. In addition, to gather an in-depth understanding of beliefs, qualitative data was also collected via interviews with attendees and organisers of the NGOs, as well as senior officials in the Ministry of Health Malaysia. Findings from the main study provided support for the utility of the TPB in identifying the determinants of the physical activity behaviour. Attitude emerged as the strongest predictor of behavioural intention across all time points. The study found a significant association between quality of life and physical activity, particularly of vigorous intensity. TPB has been shown to be effective in predicting physical activity behaviour among the Malaysian population. This study provides support of the relationship between performing physical activity and quality of life especially among the Malaysian population.

description: A strong electromagnetic field interacting with an electron system generates both the Rabi oscillations and the Stark splitting of the electron density. Changing of the electron density gives rise to nonadiabatic effects due to existence of the electron-vibrational interaction in a dissipative system. In this Letter, the mechanism of energy transfer between the electron system and the phonon reservoir is presented. This mechanism is based on establishment of the coupling between the electron states dressed by the electromagnetic field and the forced vibrations of reservoir oscillators under the action of rapid changing of the electron density with the Rabi frequency. The photoinduced vibronic coupling results in appearance of the states that are doubly dressed by interaction, first time due to the electron-photon interaction, and second time due to the electron-vibrational interaction. Moreover, this coupling opens the way to control energy which can be transferred to (heating) or removed from (cooling) the phonon reservoir depending on the parameters of the electromagnetic pulse.

description: In this letter, we propose a new routing strategy with a single free parameter $α$ only based on local information of network topology. In order to maximize the packets handling capacity of underlying structure that can be measured by the critical point of continuous phase transition from free flow to congestion, the optimal value of $α$ is sought out. By investigating the distributions of queue length on each node in free state, we give an explanation why the delivering capacity of the network can be enhanced by choosing the optimal $α$. Furthermore, dynamic properties right after the critical point are also studied. Interestingly, it is found that although the system enters the congestion state, it still possesses partial delivering capability which do not depend on $α$. This phenomenon suggests that the capacity of the network can be enhanced by increasing the forwarding ability of small important nodes which bear severe congestion.

description: Data-driven predictive analytics are in use today across a number of industrial applications, but further integration is hindered by the requirement of similarity among model training and test data distributions. This paper addresses the need of learning from possibly nonstationary data streams, or under concept drift, a commonly seen phenomenon in practical applications. A simple dual-learner ensemble strategy, alternating learners framework, is proposed. A long-memory model learns stable concepts from a long relevant time window, while a short-memory model learns transient concepts from a small recent window. The difference in prediction performance of these two models is monitored and induces an alternating policy to select, update and reset the two models. The method features an online updating mechanism to maintain the ensemble accuracy, and a concept-dependent trigger to focus on relevant data. Through empirical studies the method demonstrates effective tracking and prediction when the steaming data carry abrupt and/or gradual changes.

description: A large fraction of giant planets have gaseous envelopes that are limited to about 10 % of their total mass budget. Such planets are present in the Solar System (Uranus, Neptune) and are frequently observed in short periods around other stars (the so-called Super-Earths). In contrast to these observations, theoretical calculations based on the evolution of hydrostatic envelopes argue that such low mass envelopes cannot be maintained around cores exceeding five Earth masses. Instead, under nominal disc conditions, these planets would acquire massive envelopes through runaway gas accretion within the lifetime of the protoplanetary disc. In this work, we show that planetary envelopes are not in hydrostatic balance, which slows down envelope growth. A series of 3-dimensional, global, radiative hydrodynamical simulations reveal a steady state gas flow, which enters through the poles and exits in the disc midplane. Gas is pushed through the outer envelope in about 10 orbital timescales. In regions of the disc that are not significantly dust-depleted, envelope accretion onto cores of about five Earth masses can get stalled as the gas flow enters the deep interior. Accreted solids sublimate deep in the convective interior, but small opacity-providing grains are trapped in the flow and do not settle, which further prevents rapid envelope accretion. The transition to runaway gas accretion can however be reached when cores grow larger than typical Super-Earths, beyond 15 Earth masses, and preferably when disc opacities are below kappa=1 cm^2/g. These findings offer an explanation for the typical low-mass envelopes around the cores of Super-Earths.

description: We study the statistics of the Voronoi cell perimeter in large bi-pointed planar quadrangulations. Such maps have two marked vertices at a fixed given distance $2s$ and their Voronoi cell perimeter is simply the length of the frontier which separates vertices closer to one marked vertex than to the other. We characterize the statistics of this perimeter as a function of $s$ for maps with a large given volume $N$ both in the scaling limit where $s$ scales as $N^{1/4}$, in which case the Voronoi cell perimeter scales as $N^{1/2}$, and in the local limit where $s$ remains finite, in which case the perimeter scales as $s^2$ for large $s$. The obtained laws are universal and are characteristics of the Brownian map and the Brownian plane respectively.

Neutronic Analysis on Potential Accident Tolerant Fuel-Cladding Combination U$_3$Si$_2$-FeCrAl

description: Neutronic performance is investigated for a potential accident tolerant fuel (ATF),which consists of U$_3$Si$_2$ fuel and FeCrAl cladding. In comparison with current UO$_2$-Zr system, FeCrAl has a better oxidation resistance but a larger thermal neutron absorption cross section. U$_3$Si$_2$ has a higher thermal conductivity and a higher uranium density, which can compensate the reactivity suppressed by FeCrAl. Based on neutronic investigations, a possible U$_3$Si$_2$-FeCrAl fuel-cladding systemis taken into consideration. Fundamental properties of the suggested fuel-cladding combination are investigated in a fuel assembly.These properties include moderator and fuel temperature coefficients, control rods worth, radial power distribution (in a fuel rod), and different void reactivity coefficients. The present work proves that the new combination has less reactivity variation during its service lifetime. Although, compared with the current system, it has a little larger deviation on power distribution and a little less negative temperature coefficient and void reactivity coefficient and its control rods worth is less important, variations of these parameters are less important during the service lifetime of fuel. Hence, U$_3$Si$_2$-FeCrAl system is a potential ATF candidate from a neutronic view.

description: We present results from a Chandra X-ray Observatory study of the field X-ray source populations in 4 different observations: two high-redshift (z~0.5) clusters of galaxies 3C295 and RXJ003033.2+261819; and two non-cluster fields with similar exposure time. Surprisingly, the 0.5-2 keV source surface densities (~900-1200 sources deg**-2 at a flux limit of 1.5x10**-15 erg cm**-2s**-1) measured in an ~8'x8' area surrounding each cluster exceed by a factor of ~2 the value expected on the basis of the ROSAT and Chandra logN-logS, with a significance of ~2 sigma each, or ~3.5 sigma when the 2 fields are combined (i.e. a probability to be a statistical fluctuation of <1% and <0.04%, respectively). The same analysis performed on the non-cluster fields and on the outer chips of the cluster fields does NOT show evidence of such an excess. In both cluster fields, the summed 0.5-10 keV spectrum of the detected objects is well fitted by a power-law with Gamma~1.7 similar to AGNs and shows no sign of intrinsic absorption. The few (~10 out of 35) optical identifications available to date confirm that most of them are, as expected, AGNs but the number of redshifts available is too small to allow conclusions on their nature. We discuss possible interpretations of the overdensity in terms of: a statistical variation of Cosmic Background sources; a concentration of AGNs and/or powerful starburst galaxies associated with the clusters; and g ravitational lensing of background QSO's by the galaxy clusters. All explanations are however difficult to reconcile with the large number of excess sources detected. Deeper X-ray observations and more redshifts measurements are clearly required to settle the issue.

description: As a first step towards a quantitative understanding of the SU(4)/Sp(4) composite Higgs model through lattice calculations, we discuss the low energy effective field theory resulting from the SU(4) $\to$ Sp(4) global symmetry breaking pattern. We then consider an Sp(4) gauge theory with two Dirac fermion flavours in the fundamental representation on a lattice, which provides a concrete example of the microscopic realisation of the SU(4)/Sp(4) composite Higgs model. For this system, we outline a programme of numerical simulations aiming at the determination of the low-energy constants of the effective field theory and we test the method on the quenched theory. We also report early results from dynamical simulations, focussing on the phase structure of the lattice theory and a calculation of the lowest-lying meson spectrum at coarse lattice spacing.

description: We further study the unusual trend we found at statistically significant levels in some globular clusters, including NGC 3201: a decreasing iron abundance in red giants towards the cluster centers. We first show that recently published new estimates of iron abundance in the cluster reproduce this trend, in spite of the authors' statement about no metallicity spread due to a low scatter achieved in the [FeII/H] ratio. The mean of [FeII/H] within $R \sim 2'$ from the cluster center is lower, by $Δ$[FeII/H] = 0.05$\pm$0.02 dex, than in the outer region, in agreement with our original estimate for a much larger sample size within $R \approx 9'$. We found that an older dataset traces the trend to a much larger radial distance, comparable with the cluster tidal radius, at $Δ$[Fe/H]$\sim$0.2 dex due to higher metallicity of distant stars. We conclude the trend is reproduced by independent datasets and find that it is accompanied with both a notable same-sign trend of oxygen abundance which can vary by up to $Δ$[O/Fe]$\sim$0.3 dex within $R \approx 9'$, and opposite-sign trend of sodium abundance.

description: We present new results of point-contact Andreev-reflection (PCAR) spectroscopy in single-phase Mg_{1-x}Al_{x}B_{2} single crystals with x up to 0.32. Fitting the conductance curves of our point contacts with the two-band Blonder-Tinkham-Klapwijk model allowed us to extract the gap amplitudes Delta_{sigma} and Delta_{pi}. The gap values agree rather well with other PCAR results in Al-doped crystals and polycrystals up to x=0.2 reported in literature, and extend them to higher Al contents. In the low-doping regime, however, we observed an increase in the small gap Delta_{pi} on increasing x (or decreasing the local critical temperature of the junctions, T_{c}^{A}) which is not as clearly found in other samples. On further decreasing T_{c}^{A} below 30 K, both the gaps decrease and, up to the highest doping level x=0.32 and down to T_{c}^{A}= 12 K, no gap merging is observed. A detailed analysis of the data within the two-band Eliashberg theory shows that this gap trend can be explained as being mainly due to the band filling and to an increase in the interband scattering which is necessary to account for the increase in Delta_{pi} at low Al contents (x < 0.1). We suggest to interpret the following decrease of Delta_{pi} for T_{c}^{A} < 30 K as being governed by the onset of inhomogeneity and disorder in the Al distribution that partly mask the intrinsic effects of doping and is not taken into account in standard theoretical approaches.

description: evaluation of transformer insulation wear is one of the main conditions for their normal and long-term operation. Abrasion directly depends on the operating temperature of the equipment, external influences on it and working time. The main drawback during operation is that the insulation loses its quality due to wear and tear. This increases the humidity of the transformer during the aging process, further accelerating the aging process. By knowing the moisture content of solid insulation, you can get an idea of its wear rate and subsequent use. Various methods of frequency spectroscopy (FS) are known.

description: We present a simple analysis of the design of a passive miniature resonant optical gyroscope. By combining the requirements on the angular random walk and the bias stability, we end up with simple expressions of the minimum diameter of the ring waveguide cavity and the maximum power that should be used to probe it. Using state-of-the-art performances of photonic integrated circuit and whispering gallery mode technologies in terms of propagation losses and mode size, we show that tactical grade gyroscope performances can be achieved with a diameter of a few cm provided the detrimental influence of Kerr effect is mitigated, using for instance an active control of the unbalance in the intensities. We further extend the analysis to medium performance gyroscope and give some hints on the efforts to be made to potentially demonstrate a miniature resonant optical gyroscope with this level of performance.
STRUCTURE OF AQUEOUS AND NON-AQUEOUS ELECTROLYTE SOLUTIONS

description: As is known, solutions of electrolytes in solvents with hydrogen bonds have abnormally high values of dielectric constant, electrical conductivity (solutions of acids, alkalis and salts) and thermal conductivity. These facts, in our opinion, cannot be explained without taking into account the structure and structure of solutions. The properties of aqueous solutions of electrolytes are mainly determined by the structure of water. The dissolution of the electrolyte causes a change in the structure of water depending on the nature of the dissolved ions. The structure of water is especially important for studying the properties of water and aqueous solutions associated with the transfer phenomenon. This is due to the fact that the structure determines the conditions for the translational movement of the liquid. The article shows that water has its own, which partially changes with the appearance of a charged particle.

Chiral condensate and Dirac spectrum of one- and two-flavor QCD at nonzero $θ$-angle

description: In the $ε$-domain of QCD we have obtained exact analytical expressions for the eigenvalue density of the Dirac operator at fixed $θ\ne 0$ for both one and two flavors. These results made it possible to explain how the different contributions to the spectral density conspire to give a chiral condensate at fixed $θ$ that does not change sign when the quark mass (or one of the quark masses for two flavors) crosses the imaginary axis, while the chiral condensate at fixed topological charge does change sign. From QCD at nonzero density we have learnt that the discontinuity of the chiral condensate may move to a different location when the spectral density increases exponentially with the volume with oscillations on the order of the inverse volume. This is indeed what happens when the product of the quark masses becomes negative, but the situation is more subtle in this case: the contribution of the "quenched" part of the spectral density diverges in the thermodynamic limit at nonzero $θ$, but this divergence is canceled exactly by the contribution from the zero modes. We conclude that the zero modes are essential for the continuity of the chiral condensate and that their contribution has to be perfectly balanced against the contribution from the nonzero modes. Lattice simulations at nonzero $θ$-angle can only be trusted if this is indeed the case.

Pushing the Limits of Quantum Flux: A Rigorous Exploration of the Trinity Equation

Subjects: Quantum Holographic Lens, Quantum, holography

description: Description:
This whitepaper presents an in-depth exploration of the Trinity Equation, a novel framework that extends our understanding of quantum flux within holographic spacetime. By combining principles from quantum mechanics and general relativity, the Trinity Equation models how quantum flux behaves at extreme energy and time scales. The paper rigorously derives the equation, verifies its dimensional consistency, and analyzes its implications for quantum field theory, spacetime manipulation, and advanced quantum technologies. The results provide new insights into high-energy quantum phenomena, potentially influencing fields such as black hole thermodynamics, quantum computing, and cosmology.
Black hole masses from power density spectra: determinations and consequences

description: We analyze the scaling of the X-ray power density spectra with the mass of the black hole on the example of Cyg X-1 and Seyfert 1 galaxy NGC 5548. We show that the high frequency tail of the power density spectrum can be successfully used for determination of the black hole mass. We determine the masses of the black holes in 6 Broad Line Seyfert 1 galaxies, 5 Narrow Line Seyfert 1 galaxies and two QSOs using available power density spectra. The proposed scaling is clearly appropriate for other Seyfert galaxies and QSOs. In all but 1 normal Seyferts the resulting luminosity to the Eddington luminosity ratio is smaller than 0.15, with a source MCG -6-15-30 being an exception. The applicability of the same scaling to Narrow Line Seyfert 1 is less clear and there may be a systematic shift between the power spectra of NLS1 and S1 galaxies of the same mass, leading to underestimation of the black hole mass. However, both the method based on variability and the method based on spectral fitting show that those galaxies have relatively low masses and high luminosity to the Eddington luminosity ratio, supporting the view of those objects as analogs of galactic sources in their high/soft or very high state based on the overall spectral shape. Bulge masses of their host galaxies are similar to normal Seyfert galaxies so they do not follow the black hole mass-bulge mass relation for Seyfert galaxies, being evolutionary less advanced, as suggested by Mathur (2000). The bulge mass-black hole mass relation in our sample is consistent with being linear, with black hole to bulge ratio $\sim$ 0.03 %, similar to Wandel (1999) and Laor (1998, 2001) for low mass objects but significantly shifted from the relation of Magorrian et al. (1998) and McLure & Dunlop (2000).

description: In the framework of the Joos-Weinberg 2(2S+1)- theory for massless particles, the dynamical invariants have been derived from the Lagrangian density which is considered to be a 4- vector. A la Majorana interpretation of the 6- component "spinors", the field operators of S=1 particles, as the left- and right-circularly polarized radiation, leads us to the conserved quantities which are analogous to those obtained by Lipkin and Sudbery. The scalar Lagrangian of the Joos-Weinberg theory is shown to be equivalent to the Lagrangian of a free massless field, introduced by Hayashi. As a consequence of a new "gauge" invariance this skew-symmetric field describes physical particles with the longitudinal components only. The interaction of the spinor field with the Weinberg's 2(2S+1)- component massless field is considered. New interpretation of the Weinberg field function is proposed.

description: In the summer of 2016, physicists gathered in Torun, Poland for the 48th annual Symposium on Mathematical Physics. This Symposium was special; it celebrated the 40th anniversary of the discovery of the Gorini-Kossakowski-Sudarshan-Lindblad master equation, which is widely used in quantum physics and quantum chemistry. This article forms part of a Special Volume of the journal Open Systems & Information Dynamics arising from that conference; and it aims to celebrate a related discovery -- also by Sudarshan -- that of Quantum Maps (which had their 55th anniversary in the same year). Nowadays, much like the master equation, quantum maps are ubiquitous in physics and chemistry. Their importance in quantum information and related fields cannot be overstated. In this manuscript, we motivate quantum maps from a tomographic perspective, and derive their well-known representations. We then dive into the murky world beyond these maps, where recent research has yielded their generalisation to non-Markovian quantum processes.
