Exactly Solvable Models: The Road Towards a Rigorous Treatment of Phase Transitions in Finite Systems
Creators: name: Bugaev, K. A.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: We discuss exact analytical solutions of a variety of statistical models recently obtained for finite systems by a novel powerful mathematical method, the Laplace-Fourier transform. Among them are a constrained version of the statistical multifragmentation model, the Gas of Bags Model and the Hills and Dales Model of surface partition. Thus, the Laplace-Fourier transform allows one to study the nuclear matter equation of state, the equation of state of hadronic and quark gluon matter and surface partitions on the same footing. A complete analysis of the isobaric partition singularities of these models is done for finite systems. The developed formalism allows us, for the first time, to exactly define the finite volume analogs of gaseous, liquid and mixed phases of these models from the first principles of statistical mechanics and demonstrate the pitfalls of earlier works. The found solutions may be used for building up a new theoretical apparatus to rigorously study phase transitions in finite systems. The strategic directions of future research opened by these exact results are also discussed.

description: The objectives of this phase of the overall "Roadway Delineation" study were to evaluate the luminosity and durability of several types of glass beads and one type of plastic bead used with paint stripes and to determine their effectiveness during rainy, nighttime conditions. Eleven types of beads were evaluated. They were applied at rates approximating 4, 5, and 6 pounds per gallon (479, 599, and 719 kg/m3). Photometer and visual observations extended to about 9 months after application of test stripes.

Subjects: Arctic economies, Economic development, Sustainable development, Values

description: This policy brief focused on decision-making in the Arctic, particularly regarding the main economic activities in the region. It emphasized creating new ways for stakeholders to participate and safeguarding traditional livelihoods in decision-making. The research highlights that decision-making plays a crucial role across the JUSTNORTH policy brief series. For example, it links with planning and shaping the landscapes and seascapes in northern areas. How spaces are managed determines how stakeholders can participate in decision-making processes about those spaces. Furthermore, decision-making is vital for evaluating the environmental and social effects of economic activities in the Arctic.
Komet: A Serverless Platform for Low-Earth Orbit Edge Services

description: Low-Earth orbit satellite networks can provide global broadband Internet access using constellations of thousands of satellites. Integrating edge computing resources in such networks can enable global low-latency access to compute services, supporting end users in rural areas, remote industrial applications, or the IoT. To achieve this, resources must be carefully allocated to various services from multiple tenants. Moreover, applications must navigate the dynamic nature of satellite networks, where orbital mechanics necessitate frequent client hand-offs. Therefore, managing applications on the low-Earth orbit edge will require the right platform abstractions.
 We introduce Komet, a serverless platform for low-Earth orbit edge computing. Komet integrates Function-as-a-Service compute with data replication, enabling on-demand elastic edge resource allocation and frequent service migration against satellite orbital trajectories to keep services deployed in the same geographic region. We implement Komet as a proof-of-concept prototype and demonstrate how its abstractions can be used to build low-Earth orbit edge applications with high availability despite constant mobility. Further, we propose simple heuristics for service migration scheduling in different application scenarios and evaluate them in simulation based on our experiment traces, showing the trade-off between selecting an optimal satellite server at every instance and minimizing service migration frequency.

Selective attention in object substitution masking
Creators: name: Tata, Matthew S.
Publisher: name: University of British Columbia
Year: 2009

description: Backward masking in visual perception occurs when the visibility of a brief target stimulus is decreased by interference from another visual object appearing at the same location. Of particular interest is a type of backward masking known as object substitution, which has been shown by Di Lollo, Enns, and Rensink (1999) to be modulated by factors that also influence visual attention. The results of three experiments are presented here that corroborate their findings. It is shown that object substitution increases with the number of distractor items in the display, decreases when the target location is validly pre-cued, and is eliminated when the target can be located rapidly in the display. A theory accounting for this phenomenon has been proposed by Di Lollo and colleagues. Implicit in the theory is the notion that the mask becomes the focus of object perception mechanisms in the brain. Recent advances in the understanding of the neural mechanisms mediating attentional selection of visual objects are consistent with this theory. It is argued on theoretical grounds that attentional selection of the mask is likely to be involved in object substitution. Finally, the results of three experiments are presented that lend support to this claim. It is shown that object substitution is eliminated by the presence of distractors that divert attention from the mask at the target location. Furthermore, a mask that precedes the target in the display sequence is shown to be ineffective unless its contours are hidden in the background during the preview period. This is consistent with the findings of recent investigations into the attentional capture phenomenon and suggests that the mask may capture attention during visual search for the target.
Theory of thermal and charge transport in diffusive normal metal / superconductor junctions

description: Thermal and charge transport in the diffusive normal metal(DN) / insulator / $s$-, $d$- and p-wave superconductor junctions are studied for various situations, where we have used the Usadel equation with Nazarov's generalized boundary condition. Thermal and electrical conductance of the junction and the Lorentz ratio are calculated by varying the magnitudes of the resistance, the Thouless energy and the magnetic scattering rate in DN, the transparency of the insulating barrier, and the angle between the normal to the interface and the crystal axis of d-wave superconductors or the angle between the normal to the interface and the lobe direction of the p-wave pair potential. New general expression is derived for the calculation of the thermal conductance. It is demonstrated that the proximity effect doesn't influence the thermal conductance while the mid gap Andreev resonant states suppress it. We have also discussed a possibility of distinguishing pairing symmetries based on the dependencies of the electrical and thermal conductance on temperatures.

Subjects: CREAM Portfolio

description: Kempadoo’s research focused on smartphone imagery in order to reflect multicultural urban life and the experiences of the diasporised self, addressing imagery deploying smartphone aesthetics in artistic production. Overheard dialogue on smartphones shaped the diasporic story lines, and led to technical research with a programmer in order to develop a novel visual approach. The methodological approach explored in written form considers the seductive, hypervisualised space of self and screen associated with the city, as a perpetual line of sight, a physical and virtual urban experience and environment. Central to this space is the racialised and diasporised networked body on the move, precarious in her condition and affective in the performative encounter with herself and others. These insights developed across the visual/written artwork reflect London as a supercity in which migration for work opportunities or to escape danger abroad is commonplace yet, for many, remains precarious. Exhibition venues included Lethaby Gallery, Central Saint Martins (2015), Aljira Center for Contemporary Art, New Jersey (2016) and others.

description: In this work we initiate an integrability-based approach to multipoint conformal blocks for higher dimensional conformal field theories. Our main observation is that conformal blocks for $N$-point functions may be considered as eigenfunctions of integrable Gaudin Hamiltonians. This provides us with a complete set of differential equations that can be used to evaluate multipoint blocks.

description: We study two simple real analytic uniformly hyperbolic dynamical systems: expanding maps on the circle S1 and hyperbolic maps on the torus T2. We show that the Ruelle-Pollicott resonances which describe time correlation functions of the chaotic dynamics can be obtained as the eigenvalues of a trace class operator in Hilbert space L2(S1) or L2(T2) respectively. The trace class operator is obtained by conjugation of the Ruelle transfer operator in a similar way quantum resonances are obtained in open quantum systems. We comment this analogy.

Survey Variables Classification with Hierarchical Machine Learning

Publisher: name: Zenodo
Year: 2023

description: Recent developments in Machine Learning (ML) show robust performance in the area of Natural Language Processing (NLP) tasks, such as sentiment analysis and document classification. Our ML task is one of short text classification, specifically we are endeavouring to annotate variables using the variable name, label, question text and representation. Our task is one of multi-class classification, where accuracy is known to be sensitive to the number of labels in the dictionary. For this particular ML task we are bounding the annotation to purely learn ‘key variables’ - socio-demographic indicators which feed our Disclosure Risk Analysis (DRA).

In this presentation, we present a Hierarchical Machine Learning (HML) approach to recognising variable concepts from studies available at the UKDS. Specifically, we decompose the task into first learning the broad group to which the variable belongs, e.g. Education and then the concept within that group, e.g. Highest Educational Qualification.

At a high level, we use a mix of shallow and deep learning models to minimize the number of target class labels and boost the overall performance of each individual algorithm. We present details of the cost function simplification process and each hierarchy metrics and benchmarks.
Second order contributions to the absorption of massive particles

Publisher: name: arXiv
Year: 2008

description: Recently, in analogy with multiphoton ionization, it has been suggested that multiparticle ionization can also be induced by massive systems. We explore in this paper the possibility that multiparticle absorption processes can also take place for massive particles. To study it we consider, in a perturbative way, a model of absorption which illustrates the analogies with Glauber's scheme for photons and previous analysis on matter-waves coherence. A major advantage of this approach is that the dependence of the absorption rates on the wavefunction of the incident system can be analyzed in an explicit way. The calculations confirm the form of the second order (two-particle) contributions.

description: The recently discovered fully charmed tetraquark candidate $X(6900)$ is analyzed within the frameworks of effective-range expansion, compositeness relation and width saturation, and a coupled multichannel dynamical study. By taking into account constraints from heavy-quark spin symmetry, the coupled-channel amplitude including the $J/ψJ/ψ,~ χ_{c0}χ_{c0}$ and $χ_{c1}χ_{c1}$ is constructed to fit the experimental di-$J/ψ$ event distributions around the energy region near $6.9$ GeV. Another dynamical two-coupled-channel amplitude with the $J/ψJ/ψ$ and $ψ(3770) J/ψ$ is also considered to describe the same datasets. The three different theoretical approaches lead to similar conclusions that the two-meson components do not play dominant roles in the $X(6900)$. Our determinations of the resonance poles in the complex energy plane from the refined coupled-channel study are found to be consistent with the experimental analyses. The coupled-channel amplitudes also have another pole corresponding to a narrow resonance $X(6825)$ that we predict sitting below the $χ_{c0}χ_{c0}$ threshold and of molecular origin. We give predictions to the line shapes of the $χ_{c0}χ_{c0}$ and $χ_{c1}χ_{c1}$ channels, which could provide a useful guide for future experimental measurements.

Our research corrects inaccuracies previously reported in the literature and addresses areas where the Wentzel--Kramers--Brillouin (WKB) approximation proves inadequate. Moreover, we introduce and evaluate a novel spectral technique designed to consolidate recent advancements in formulating QNM boundary conditions at both the wormhole throat and space-like infinity. This innovative approach bridges critical gaps in existing methodologies and enhances the accuracy and applicability of QNM analysis in the study of wormhole physics.

Quantum theory cannot violate a causal inequality

subject: FOS: Physical sciences

description: Within quantum theory, we can create superpositions of different causal orders of events, and observe interference between them. This raises the question of whether quantum theory can produce results that would be impossible to replicate with any classical causal model, thereby violating a causal inequality. This would be a temporal analogue of Bell inequality violation, which proves that no local hidden variable model can replicate quantum results. However, unlike the case of non-locality, we show that quantum experiments \emph{can} be simulated by a classical causal model, and therefore cannot violate a causal inequality.

description: Our X-ray study of the nuclear activity in a new sample of six quiescent early-type galaxies, and in a larger sample from the literature, confirmed (Soria et al., Paper I) that the Bondi accretion rate of diffuse hot gas is not a good indicator of the supermassive black hole (SMBH) X-ray luminosity. Here we suggest that a more reliable estimate of the accretion rate must include the gas released by the stellar population inside the sphere of influence of the SMBH, in addition to the Bondi inflow of hot gas across that surface. We use optical surface-brightness profiles to estimate the mass-loss rate from stars in the nuclear region: we show that for our sample of galaxies it is an order of magnitude higher (~ 10^{-4} - 10^{-3} M_sun/yr) than the Bondi inflow rate of hot gas, as estimated from Chandra (Paper I). Only by taking into account both sources of fuel can we constrain the true accretion rate, the accretion efficiency, and the power budget. Radiatively efficient accretion is ruled out, for quiescent SMBHs. For typical radiatively inefficient flows, the observed X-ray luminosities of the SMBHs imply accretion fractions ~ 1 - 10% (ie, ~ 90 - 99% of the available gas does not reach the SMBH) for at least five of our six target galaxies, and most of the other galaxies with known SMBH masses. We discuss the conditions for mass conservation inside the sphere of influence, so that the total gas injection is balanced by accretion plus outflows. We show that a fraction of the total accretion power (mechanical plus radiative) would be sufficient to sustain a self-regulating, slow outflow which removes from the nuclear region all the gas that does not sink into the BH (``BH feedback''). The rest of the accretion power may be carried out in a jet, or advected. We also discuss scenarios that would lead to an intermittent nuclear activity.

title: Perichoresis and participation : union between the persons of God and between God and humanity
Creators: name: Cress, Graydon
Publisher: name: University of St Andrews
Year: 2019

description: There exists a lack of clarity concerning the concept of perichoresis in contemporary theology. Although most theologians hold a similar formal definition of this term which attempts to describe the union of the persons of the Trinity, the variety of ways with which it is being used as a tool renders it potentially unhelpful. The most serious area of theology which is affected by these differences of usage for perichoresis is that of human participation with the divine. In order to seek clarity and logical consistency between these two concepts, this thesis first provides a brief overview of trinitarian theology as it stands today and expresses why these concepts are of importance at this time. Secondly, it explores the origins of perichoresis, categorizes the different ways modern theologians utilize the concept, and provides a definition which may be useful when moving forward. Thirdly, the thesis examines the concept of human participation with God, starting with an overview of the Eastern concept of theosis, followed by a categorization of the different ways the concept of human participation is expressed today, and ending with a brief definition which may be helpful in future conversations about the topic. Finally, the thesis explores the theological movements which are logically allowable when one takes his or her doctrine of perichoresis to bear on the concept of human participation with God. I argue that there are ways of using perichoresis which logically necessitate certain understandings of participation and logically prohibit others. The twofold goals of this thesis are, first, to provide clarity of language when discussing the concept of perichoresis by categorizing the thoughts of theologians into an understandable framework, and second, to encourage scholars to examine carefully the ways in which their understanding of perichoresis affects their understanding of human participation with the divine.

description: The objective of this paper is, in the main, twofold: Firstly, to develop an algebraic setting for dealing with Bell polynomials and related extensions. Secondly, based on the author's previous work on multivariate Stirling polynomials (2015), to present a number of new results related to different types of inverse relationships, among these (1) the use of multivariable Lah polynomials for characterizing self-orthogonal families of polynomials that can be represented by Bell polynomials, (2) the introduction of `generalized Lagrange inversion polynomials' that invert functions characterized in a specific way by sequences of constants, (3) a general reciprocity theorem according to which, in particular, the partial Bell polynomials $B_{n,k}$ and their orthogonal companions $A_{n,k}$ belong to one single class of Stirling polynomials: $A_{n,k}=(-1)^{n-k}B_{-k,-n}$. Moreover, of some numerical statements (such as Stirling inversion, Schlömilch-Schläfli formulas) generalized polynomial versions are established. A number of well-known theorems (Jabotinsky, Mullin-Rota, Melzak, Comtet) are given new proofs.

title: The effects of forage supplementation on grazing dairy cows
Creators: name: Hameleers, A. (A.L.J.)
Publisher: name: University of Glasgow
Year: 1999

description: This thesis first presents a review of the literature on intake from grazed herbage. It reviews animal factors and how theoretical ruminant intake concepts could be used in the grazing situation. The effects of sward conditions on herbage intake and various supplementation strategies and supplementation practices are evaluated. After which the various possible measurement techniques for estimating herbage intake are discussed. A number of experiments are presented, all carried out at the Scottish Agricultural College, Crichton Royal Farm. In the first experiment the n-alkane technique for estimating herbage intake and diet selection in dairy cows offered perennial ryegrass (Lolium perenne)/white clover (Trifolium repens) herbage was evaluated. In a second experiment, the potential use of n-alkanes was evaluated for estimating supplementary grass silage intake. In the first supplementation experiment, two forage supplementation systems were examined over a 15 week period, using a continuous design. Thereafter two experiments are described investigating the effect of ME-content and degradability of the forage supplement on animal performance and total dry matter intake. In these two experiments two groups of grazing lactating dairy cows were offered straw/sugar beet pulp mixtures of different straw and sugar beet pulp content. The final experiment investigated the effect of forage supplement dry matter content and stage of lactation on dairy cow performance and herbage intake response. The different types of supplements did not significantly affect animal performance. The yield of fat and protein corrected milk (FPCM) was significantly (P<0.01) affected by stage of lactation. Forage supplementation resulted in a negative milk production response in late lactation cows and in a positive milk production response in early lactation. However, this response was not significantly different. The increase in FPCM with supplementation was significantly (P<0.05) different between early (+3.3 kg FPCM day-1) and late lactation cows (-0.5 kg FPCM day-1). The results of this experiment suggest that early and late lactation animals will consume similar amounts of forage supplement when offered, but will respond differently with a positive response in early lactation and negative response in late lactation animals.

description: Coronal Mass Ejections (CMEs) are key drivers of space weather activity but most predictions have been limited to the expected arrival time of a CME, rather than the internal properties that affect the severity of an impact. Many properties, such as the magnetic field density and mass density, follow conservation laws and vary systematically with changes in the size of a CME. We present ANTEATR-PARADE, the newest version of the ANTEATR arrival time model, which now includes physics-driven changes in the size and shape of both the CME's central axis and its cross section. Internal magnetic and thermal and external drag forces affect the acceleration of the CME in different directions, inducing asymmetries between the radial and perpendicular directions. These improvements should lead to more realistic CME velocities, both bulk and expansion, sizes and shapes, and internal properties. We present the model details, an initial illustration of the general behavior, and a study of the relative importance of the different forces. The model shows a pancaking of both the cross section and central axis of the CME so that their radial extent becomes smaller than their extent in the perpendicular direction. We find that the initial velocities, drag, any form of cross section expansion, and the precise form of thermal expansion have strong effects. The results are less sensitive to axial forces and the specific form of the cross section expansion.

description: Meristogenys stigmachilus.
We recorded calls of six males on 5 March 2023 at Mahua. All males were calling on vegetation within 1.5 m of the ground, and within 3 m of the stream edge, and close to a paved path alongside the stream between the park entrance and the Mahua waterfall. Males started calling around dusk, and calling activity seemed to be strongest in the first three hours after dusk. There was no rain during recording hours. Other species active and calling in the same vicinity included Huia cavitympanum, Leptolalax pictus, Meristogenys orphnocnemis, and at least one Ansonia species. Recordings were between 3:07 and 9:23 min long, each with 1–30 calls at irregular intervals (Table 1). Visual inspection and measurements of dominant frequency, call duration, and delta frequency showed wide variation in call parameters and exact shape of calls (Fig. 2; supplementary material). For simplicity, we grouped calls into four broad types, but emphasise that three of the four groups contain variation in the exact call shape as well as in the dominant frequency, duration, and delta frequency. Type A: flat or slightly increasing, B: long slow decline, C: short rapid decline, and D: staccato. Due to the wide range of measured parameters within groups A–C, we report here the range of values observed rather than mean ± SE and provide data of each individual call in supplementary material. Type D (staccato) calls were much more consistent, with a dominant frequency of 3064.3 ± 63.9 (mean ± SE), consisting of 17.4 ± 3.3 pulses at a rate of 16.7 ± 0.3 pulses/sec.
Little has been published about this species beyond its initial description, and during repeated nocturnal surveys in 2022, the authors (JAS, PVG, and PY) noted that while existing records state that this species has fine dark spots or melanophores on the chest and throat (Inger et al., 2017) (https://www.frogsofborneo.org/frogs/ranidae/meristogenys/ stigmachilus), these spots only appear during the day or after preservation, while during nocturnal observations the chest and throat are white. Additionally, males and females were previously reported to be 43–50 mm and 69–80 mm SVL, respectively, but our observations included males of 45–53 mm and females 82–84 mm SVL.

For 3-manifolds $M$ with first Betti number 2 we give a characterization in terms of some generalized self-linking numbers of $M$, for there to exist a family of $\mathbb{Z}_n$ covering spaces, $M_n$, in which $β_1(M_n)$ increases linearly with $n$. The latter generalizes work of M. Katz and C. Lescop [KL], by showing that the non-vanishing of any one of these invariants of $M$ is sufficient to guarantee certain optimal systolic inequalities for $M$ (by work of Ivanov and Katz [IK]).

description: This article aims to investigate various anisotropic stellar models in the background of $f(\mathcal{R},\mathcal{T},\mathcal{Q})$ gravity, where $\mathcal{Q}=\mathcal{R}_{φ\vartheta}\mathcal{T}^{φ\vartheta}$. In this regard, we adopt two standard models as $\mathcal{R}+ζ\mathcal{Q}$ and $\mathcal{R}+ζ\mathcal{R}\mathcal{Q}$, where $ζ$ symbolizes an arbitrary coupling parameter. We take spherical interior geometry and find solution to the modified gravitational field equations corresponding to each model by employing the `Tolman IV' spacetime. We need an additional constraint to close the system of field equations, thus the $\mathbb{MIT}$ bag model equation of state is chosen. The effects of modified theory on physical properties of six compact stars like PSR J 1614 2230,~SMC X-1,~Cen X-3,~PSR J 1903+327,~SAX J 1808.4-3658 and 4U 1820-30 are analyzed by using their respective masses and radii. We also determine the values of three unknowns involving in Tolman IV solution as well as the bag constant for each star at the hypersurface. Furthermore, various characteristics of the resulting solutions are examined through graphical interpretation for $ζ=\pm5$. Finally, we explore the stability of the compact objects through two different approaches. We conclude that our model-I produces physically acceptable structures corresponding to each star candidate for both values of $ζ$ whereas model-II is stable only for $ζ=5$.

description: Pinnularia manausensis A.C. Pereira & Torgan sp. nov. (Figs 2–6, 22–25)
Type: — BRAZIL. Amazonas: Tupé Lake 03 o 02'17,1''S, 60 o 15'45,3''W, 16 December 2003, Melo S., plankton, station 9, (Holotype HAS slide n o 6492!, holotype = Figure 2, row sample; isotypes HAS 109582!; BR 4319!).
Valves linear with slightly triundulate margins, middle inflated, subcapitate rounded ends (Figs 2–6, 22), valve length 121–130.2 µm, breadth 15.5–18.5 µm, length/breadth ratio 7.0–7.8. Axial area 1/3 width of valve, widening near central area. Central area present, generally forming symmetric fascia. Raphe lateral, proximal raphe endings bent in same direction (Fig. 24), terminal fissures sickle-shaped (Fig. 23). Terminal raphe endings curved towards secondary side of valves, while drop-like central pores deflect to primary side (Figs 23, 24). Striae (10–11 in 10 µm) radiate at middle, convergent at ends. Alveoli pattern with 3–7 rows of rounded areolae, each row with 12–13 areolae in 2 µm (Fig. 25).
Etymology:— Dedicated to Manaus city, Amazonas State.
Observations:— P. monicae Metzeltin & Lange-Bertalot (2007: 211) exhibits some similarities to P. manausensis but differs by its valve outline and axial area shape (lanceolate), which is not linear as it is in P. manausensis. Furthermore, P. monicae has broadly rounded poles and a lower density of striae (Table 2).
Pinnularia manausensis was observed in the plankton, during low waters, which showed 0.30 m depth, 0.30 m transparency, high temperature (28.6ºC), low pH (4.7) and conductivity (7.10 µS.cm -1).

description: We demonstrate that by carefully analyzing the temperature dependent characteristics of the I-V measurements for a given complex system it is possible to determine whether it is composed of a single, double or multiple quantum-dot structure. Our approach is based on the orthodox theory for a double-dot case and is capable of simulating I-V characteristics of systems with any resistance and capacitance values and for temperatures corresponding to thermal energies larger than the dot level spacing. We compare I-V characteristics of single-dot and double-dot systems and show that for a given measured I-V curve considering the possibility of a second dot is equivalent to decreasing the fit temperature. Thus, our method allows one to gain information about the structure of an experimental system based on an I-V measurement.

description: Intelligent reflecting surface (IRS) enhanced multi-unmanned aerial vehicle (UAV) non-orthogonal multiple access (NOMA) networks are investigated. A new transmission framework is proposed, where multiple UAV-mounted base stations employ NOMA to serve multiple groups of ground users with the aid of an IRS. The three-dimensional (3D) placement and transmit power of UAVs, the reflection matrix of the IRS, and the NOMA decoding orders among users are jointly optimized for maximization of the sum rate of considered networks. To tackle the formulated mixed-integer non-convex optimization problem with coupled variables, a block coordinate descent (BCD)-based iterative algorithm is developed. Specifically, the original problem is decomposed into three subproblems, which are alternatingly solved by exploiting the penalty method and the successive convex approximation technique. The proposed BCD-based algorithm is demonstrated to be able to obtain a stationary point of the original problem with polynomial time complexity. Numerical results show that: 1) the proposed NOMA-IRS scheme for multi-UAV networks achieves a higher sum rate compared to the benchmark schemes, i.e., orthogonal multiple access (OMA)-IRS and NOMA without IRS; 2) the use of IRS is capable of providing performance gain for multi-UAV networks by both enhancing channel qualities of UAVs to their served users and mitigating the inter-UAV interference; and 3) optimizing the UAV placement can make the sum rate gain brought by NOMA more distinct due to the flexible decoding order design.

description: Fires create substantial ecosystem disturbances, which affect biodiversity and climate processes. Previously, satellite-derived burned areas were assessed, and fire patches and morphological traits related to fire spread functions identified. The cut-off value in days is a critical parameter for the algorithms used to identify fire patches, as it identifies when two contiguous burned pixels should be grouped together as one patch. Our understanding of how fire patches and their morphologies change with the cut-off values between satellite sensors is currently insufficient for model development and pyrogeographic studies. We have addressed this using the FRY v1.0 global database of fire patch functional traits, with cut-off values of 3, 5, 9, and 14 days, derived from two burned area products, the MERIS Fire_cci version 4.1 and MODIS MCD64A1 collection 6, from two satellite sensors with different spatial and temporal resolutions. We intercompared the FRY products with functional diversity trait methods that assess their morphological pyrodiversity structures and dissimilarities. We have assessed the functional pyrodiversity of the FRY products with four cut-off values, for fire patches ≥ 300 ha, on 1° resolution tiles for the world and Global Fire Emissions Database (GFED) region scales, from 2005–2011. The functional structures and dissimilarities between the FRY products varied with the regions, while cut-off value sensitivity varied with the regions and between the satellite sensor products. These variations in functional structures and dissimilarities mirrored the regional fire spread processes and satellite sensor resolutions. The functional pyrodiversity that varied with the regions and similar cut-off values did not lead to the best agreement between the satellite sensor products. These variations reinforce the need to combine high temporal resolution optical sensors with radar in tropical regions, to consistently meet the monitoring requirements and for international organizations, to enable improved assessments of climate and biodiversity.

description: A nationwide on-line survey of 3,000 households was conducted. Households were randomly selected from the database of 400,000 households who make up Ipsos-NPD marketing research panel. The purpose of this study is to examine how a household meal planner's perception of the importance of various dietary components in selecting food items is influenced by the person's or the household's socio-demographic factors and health attitude. Annual household income affected fat, calcium, and cholesterol considerations significantly but did not make any impact on the consideration of salt when consumers selected food items. Hence, the result implies that as income level increases, household meal planners are more likely to be concerned about fat, calcium and cholesterol. Older household meal planners were more likely to consider salt, calcium and cholesterols than their younger counterparts. Health attitude of the household meal planners significantly influenced their nutritional concerns. Those meal planners who read nutritional labels on food products and changed diet to reduce the risk of disease were concerned about all four types of nutritional factors included in the study.

description: In a general setting, we introduce a new bipartite state property sufficient for the validity of the perfect correlation form of the original Bell inequality for any three bounded quantum observables. A bipartite quantum state with this property does not necessarily exhibit perfect correlations. The class of bipartite states specified by this property includes both separable and nonseparable states. We prove analytically that, for any dimension d>2, every Werner state, separable or nonseparable, belongs to this class.
