description: The demand response provides an opportunity for load serving entities (LSEs) that operate retail electricity markets (REMs) to strategically purchase energy and provide reserves in wholesale electricity markets (WEMs). This paper concerns with the problem of simultaneously determining the optimal energy bids and reserve offers an LSE submits to the WEM as well as the optimal energy and reserve prices it sets in the REM so as to maximize its profit. To this end, we explicitly model the tri-layer market structure that consists of a WEM, a REM, and a set of end user customers, so as to capture the coupling between the bidding problem and the pricing problem. Based on the tri-layer market model, we then formulate the joint bidding and pricing problem as a bi-level programming problem and further transform it into a single-level mixed integer linear programming problem, which can be solved efficiently. Numerical studies using the IEEE test cases are presented to illustrate the application of the proposed methodology as well as to reveal several interesting characteristics of the LSE's profit-seeking behavior.

description: We study the half-chain entanglement entropy in the ground state of the spin-1/2 XX chain across an extended random defect, where the strength of disorder decays with the distance from the interface algebraically as $Δ_l\sim l^{-κ}$. In the whole regime $κ\ge 0$, the average entanglement entropy is found to increase logarithmically with the system size $L$ as $S_L\simeq\frac{c_{\rm eff}(κ)}{6}\ln L+const$, where the effective central charge $c_{\rm eff}(κ)$ depends on $κ$. In the regime $κ<1/2$, where the extended defect is a relevant perturbation, the strong-disorder renormalization group method gives $c_{\rm eff}(κ)=(1-2κ)\ln2$, while, in the regime $κ\ge 1/2$, where the extended defect is irrelevant in the bulk, numerical results indicate a non-zero effective central charge, which increases with $κ$. The variation of $c_{\rm eff}(κ)$ is thus found to be non-monotonic and discontinuous at $κ=1/2$.

description: We present a practical scheme for the decomposition of a bipartite mixed state into a sum of direct products of local density matrices, using the technique developed in Li and Qiao (Sci. Rep. 8: 1442, 2018). In the scheme, the correlation matrix which characterizes the bipartite entanglement is first decomposed into two matrices composed of the Bloch vectors of local states. Then we show that the symmetries of Bloch vectors are consistent with that of the correlation matrix, and the magnitudes of the local Bloch vectors are lower bounded by the correlation matrix. Concrete examples for the separable decompositions of bipartite mixed states are presented for illustration.

description: The origin and nature of extreme energy cosmic rays (EECRs), which have energies above the 50 EeV, the Greisen-Zatsepin-Kuzmin (GZK) energy limit, is one of the most interesting and complicated problems in modern cosmic-ray physics. Existing ground-based detectors have helped to obtain remarkable results in studying cosmic rays before and after the GZK limit, but have also produced some contradictions in our understanding of cosmic ray mass composition. Moreover, each of these detectors covers only a part of the celestial sphere, which poses problems for studying the arrival directions of EECRs and identifying their sources. As a new generation of EECR space detectors, TUS (Tracking Ultraviolet Set-up), KLYPVE and JEM-EUSO, are intended to study the most energetic cosmic-ray particles, providing larger, uniform exposures of the entire celestial sphere. The TUS detector, launched on board the Lomonosov satellite on April 28, 2016, from Vostochny Cosmodrome in Russia, is the first of these. It employs a single-mirror optical system and a photomultiplier tube matrix as a photo-detector and will test the fluorescent method of measuring EECRs from space. Utilizing the Earth's atmosphere as a huge calorimeter, it is expected to detect EECRs with energies above 100 EeV. It will also be able to register slower atmospheric transient events: atmospheric fluorescence in electrical discharges of various types including precipitating electrons escaping the magnetosphere and from the radiation of meteors passing through the atmosphere. We describe the design of the TUS detector and present results of different ground-based tests and simulations.

description: I was a child during the war, living in a small village in South Wales. At the age of 3 or 4 years I remember American soldiers driving through the village in open trucks. Everyone was waving and the soldiers were waving back. In one of the trucks there were some black men waving - I had never seen a black face before. Everyone was happy, especially as they were throwing sweets, though I was sad that I didn't get any!I remember VE Day in the same village in 1945. I knew there was something special going on, and that Hitler was a very bad man. My friend and I stood at the garden gate and some young men from the village had an effigy of Hitlerand said they were going to hang him from a lamppost. We thought it really was Hitler and seeing him strung up on a lamppost made us very, very frightened. Then we had a street party on some ground nest to the main road. Bus drivers stopped and shouted and waved to us. It was a very special day!

description: Contribution from WP11 to SETAC Europe 26th LCA Symposium
description: Background and Purpose: In the social life cycle assessment (S-LCA), selecting impact subcategories is a crucial component of the social life cycle impact assessment (S-LCIA) phase. Projects with limited time and resources often face challenges in including numerous impact subcategories, making the prioritization of the most relevant subcategories essential for conducting meaningful S-LCA and generating relevant results for stakeholders. This study demonstrates the use of participatory approaches for prioritizing impact subcategories in the context of an S-LCA of clean solid biofuels produced from encroacher bushes in Southern Africa. The EU Horizon 2020 SteamBioAfrica project (GA 101036401) intends to produce a scalable and replicable technology platform to support a large-scale transformation of the widespread problem of invasive and encroaching biomass into a sustainable and secure source of bioenergy and biochemicals in Southern Africa. The project also addresses the effects of this novel bioenergy system on other environmental and societal challenges in the region, including climate change impacts, energy insecurity, water shortage, social inclusion, and unemployment. Methods: Participatory tools, including brainstorming sessions, participatory subcategory ranking, and semi-structured interviews, were utilized to engage stakeholders across the entire biomass-based value chain in Southern Africa. Results: This approach facilitated the identification of primary concerns and the definition of priority impact subcategories for each stakeholder category. For example, unemployment was one key concern to prioritize for smallholders, while supplier relationship is one of the most relevant impact subcategories for representatives of commercial farmers (value chain actor stakeholder category). Conclusions: The use of participatory approaches proved valuable in identifying and prioritizing impact subcategories for the S-LCA, ensuring that the assessment of potential social effects is more authentic and relevant to local actors. Moreover, engaging stakeholders enhanced the understanding of the assessed system and its value chain, contributing to other phases of the S-LCA.

description: To date, scholars are somewhat divided to what extent conflicts with parents are detrimental for adolescent development and their well-being, some argue that conflicts can even be beneficial (e.g., Adams & Laursen, 2007; Laursen & Hafen, 2010). In this paper we argue that positive and negative effects of conflict may co-exist but potentially play out on different timescales. A structural examination of this question of how time may affect these estimates is currently lacking – but a crucial first step is to move our field beyond time-naïve designs towards a more dynamic understanding of the transactional processes between parents and adolescents. Hence, the current study addresses this gap in our knowledge by using two datasets (N1 = 159, t1max = 100 and N2 = 259, t2max = 26) which span several timescales (from days to three months). This unique feature of these datasets allows to aggregate the same measures of the same samples across six different timescales (daily, weekly, bi-weekly, monthly, bi-monthly, and three-monthly) while holding other factors (e.g., sample, questionnaires, and analytical approach) constant. Differences between estimates are thus solely due to differences in timescale.

description: Pseudorapidity and azimuthal three-particle correlations are studied based on a correlated-cluster model of multiparticle production. The model provides a common framework for correlations in proton-proton and heavy-ion collisions allowing easy comparison with the measurements. It is shown that azimuthal cluster correlations are definitely required in order to understand three-particle correlations in the near-side ridge effect. This is similar to the explanation of the ridge phenomenon found in our previous analysis of two-particle correlations and generalizes the model to higher-order correlations.

Effective-range corrections to the ground-state energy of the weakly-interacting Bose gas in two dimensions

description: Nonuniversal effects due to leading effective-range corrections are computed for the ground-state energy of the weakly-coupled repulsive Bose gas in two spatial dimensions. Using an effective field theory of contact interactions, these corrections are computed first by considering fluctuations around the mean-field free energy of a system of interacting bosons. This result is then confirmed by an exact calculation in which the energy of a finite number of bosons interacting in a square with period boundary conditions is computed and the thermodynamic limit is explicitly taken.

description: We address a number of outstanding questions associated with the analytic properties of the universal equation of state of the $ϕ^4$ theory, which describes the critical behavior of the Ising model and ubiquitous critical points of the liquid-gas type. We focus on the relation between spinodal points that limit the domain of metastability for temperatures below the critical temperature, i.e., $T < T_{\rm c}$, and Lee-Yang edge singularities that restrict the domain of analyticity around the point of zero magnetic field $H$ for $T > T_{\rm c}$. The extended analyticity conjecture (due to Fonseca and Zamolodchikov) posits that, for $T < T_{\rm c}$, the Lee-Yang edge singularities are the closest singularities to the real $H$ axis. This has interesting implications, in particular, that the spinodal singularities must lie off the real $H$ axis for $d < 4$, in contrast to the commonly known result of the mean-field approximation. We find that the parametric representation of the Ising equation of state obtained in the $\varepsilon = 4-d$ expansion, as well as the equation of state of the ${\rm O}(N)$-symmetric $ϕ^4$ theory at large $N$, are both nontrivially consistent with the conjecture. We analyze the reason for the difficulty of addressing this issue using the $\varepsilon$ expansion. It is related to the long-standing paradox associated with the fact that the vicinity of the Lee-Yang edge singularity is described by Fisher's $ϕ^3$ theory, which remains nonperturbative even for $d\to 4$, where the equation of state of the $ϕ^4$ theory is expected to approach the mean-field result. We resolve this paradox by deriving the Ginzburg criterion that determines the size of the region around the Lee-Yang edge singularity where mean-field theory no longer applies.

description: En 2022, le secteur de l'assurance au Maroc a maintenu une croissance significative, avec des primes émises atteignant 49,6 milliards de dirhams, en hausse de 9,9%. L'objectif principal était de consolider la robustesse du secteur, démontrée par la progression de l'assurance vie de 12,5% et de l'assurance non-vie de 7,7%. Les résultats techniques nets ont également enregistré une amélioration notable, avec une augmentation de 31,1% pour l'assurance vie et de 16% pour l'assurance non-vie. Bien que la réassurance ait légèrement diminué en termes de primes acceptées, cette baisse a été compensée par une augmentation du solde de cession à 101,8%. Les placements financiers ont également connu une croissance, totalisant 221,3 milliards de dirhams, avec un résultat net en hausse de 31,4%, atteignant 4,2 milliards de dirhams et un ROE de 9,5%. La distribution des produits d'assurance a également prospéré, avec une hausse de 16% de la production des intermédiaires d'assurances et BGD, ainsi qu'une augmentation de 16,5% dans la production bancassurance. L'assurance Takaful a clôturé son premier exercice avec un chiffre d'affaires de 11,8 millions MAD, marquant une étape dans la diversification des produits. Les lois 59-13 et 87-18 ont respectivement modifié et complété la loi 17-99 portant code des assurances, introduisant ainsi un cadre réglementaire pour l'assurance Takaful et la séparation des comptes. Ces indicateurs soulignent la résilience et la vitalité continues du secteur des assurances au Maroc, promettant une contribution significative au développement économique et social.

description: Evolutionary dynamics are controlled by a number of driving forces, such as natural selection, random genetic drift and dispersal. In this perspective article, we aim to emphasize that these forces act at the population level, and that it is a challenge to understand how they emerge from the stochastic and deterministic behaviour of individual cells. Even the most basic steric interactions between neighbouring cells can couple evolutionary outcomes of otherwise unrelated individuals, thereby weakening natural selection and enhancing random genetic drift. Using microbial examples of varying degrees of complexity, we demonstrate how strongly cell–cell interactions influence evolutionary dynamics, especially in pattern-forming systems. As pattern formation itself is subject to evolution, we propose to study the feedback between pattern formation and evolutionary dynamics, which could be key to predicting and potentially steering evolutionary processes. Such an effort requires extending the systems biology approach from the cellular to the population scale. This article is part of the theme issue ‘Self-organization in cell biology’.

description: Classical reverse-mode automatic differentiation (AD) imposes only a small constant-factor overhead in operation count over the original computation, but has storage requirements that grow, in the worst case, in proportion to the time consumed by the original computation. This storage blowup can be ameliorated by checkpointing, a process that reorders application of classical reverse-mode AD over an execution interval to tradeoff space \vs\ time. Application of checkpointing in a divide-and-conquer fashion to strategically chosen nested execution intervals can break classical reverse-mode AD into stages which can reduce the worst-case growth in storage from linear to sublinear. Doing this has been fully automated only for computations of particularly simple form, with checkpoints spanning execution intervals resulting from a limited set of program constructs. Here we show how the technique can be automated for arbitrary computations. The essential innovation is to apply the technique at the level of the language implementation itself, thus allowing checkpoints to span any execution interval.

description: This study assesses the effects of urban governance structure on the spatial expansion of metropolitan areas. A more fragmented governance structure, represented by a high number of administrative units with decision power on land use per inhabitant, is expected to increase the competition between small towns in the suburbs of metropolitan areas to attract households and workers, which, in turn, induces more land uptake. We study empirically the relationship between administrative fragmentation and the spatial size of cities in a sample of 180 metropolitan areas in the contexts of the US and Europe in the period 2000-2012. Results shed light on the structural differences between the two broad regions and suggest that administrative fragmentation impacts positively on land uptake in both the United States and Europe, although to different extents.

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: The theory of correlated electron systems on a lattice proves notoriously complicated because of the exponential growth of Hilbert space. Mean-field approaches provide valuable insight when the self-energy has a dominant local structure. Additionally, the extraction of effective low-energy theories from the generalized many-body representation is highly desirable. In this respect, the rotational-invariant slave boson (RISB) approach in its mean-field formulation enables versatile access to correlated lattice problems. However in its original form, due to numerical complexity, the RISB approach is limited to about three correlated orbitals per lattice site. We thus present a thorough symmetry-adapted advancement of RISB theory, suited to efficiently deal with multi-orbital Hubbard Hamiltonians for complete atomic-shell manifolds. It is utilized to study the intriguing problem of Hund's physics for three- and especially five-orbital manifolds on the correlated lattice, including crystal-field terms as well as spin-orbit interaction. The well-known Janus-face phenomenology, i.e. strenghtening of correlations at smaller-to-intermediate Hubbard $U$ accompanied by a shift of the Mott transition to a larger $U$ value, has a stronger signature and more involved multiplet resolution for five-orbital problems. Spin-orbit interaction effectively reduces the critical local interaction strength and weakens the Janus-face behavior. Application to the realistic challenge of Fe chalcogenides underlines the subtle interplay of the orbital degrees of freedom in these materials

description: We investigate signatures of spin and orbital states of $R$VO$_{3}$ ($R$=Y and La) in the optical conductivity using density functional theory plus dynamical mean-field theory (DFT+DMFT). From the assignment of multiplet states to optical transitions, DFT+DMFT reproduces experimental temperature dependent evolutions of optical conductivity for both YVO$_{3}$ and LaVO$_{3}$. We also show that the optical conductivity is a useful quantity to probe the evolution of the orbital state even in the absence of spin order. The result provides a reference to investigate spin and orbital states of ${t_{2g}}^{2}$ vanadate systems which is an important issue for both fundamental physics on spin and orbital states and applications of vanadates by means of orbital state control.

A numerical method to simulate such a system, for a physically relevant number of barriers, is proposed. It is shown that the disordered model converges to the periodic case as $N$ increases, with a rate of convergence which depends on the disorder degree. Compression always leads to a decrease of the transmission coefficient which may be exploited to design nano-technological sensors. Effective choices for the physical parameters to improve the sensitivity are provided. Eventually large fluctuations and rate functions are analysed.

description: The cage problem asks for the smallest number $c(k,g)$ of vertices in a $k$-regular graph of girth $g$ and graphs meeting this bound are known as cages. While cages are known to exist for all integers $k \ge 2$ and $g \ge 3$, the exact value of $c(k, g)$ is known only for some small values of $k, g$ and three infinite families where $g \in \{6, 8, 12\}$ and $k - 1$ is a prime power. These infinite families come from the incidence graphs of generalized polygons. Some of the best known upper bounds on $c(k,g)$ for $g \in \{6, 8, 12\}$ have been obtained by constructing small regular induced subgraphs of these cages. In this paper, we first use the Expander Mixing Lemma to give a general lower bound on the size of an induced $k$-regular subgraph of a regular bipartite graph in terms of the second largest eigenvalue of the host graph. We use this bound to show that the known construction of $(k,6)$-graphs using Baer subplanes of the Desarguesian projective plane is the best possible. For generalized quadrangles and hexagons, our bounds are new. In particular, we improve the known lower bound on the size of a $q$-regular induced subgraphs of the classical generalized quadrangle $\mathsf{Q}(4,q)$ and show that the known constructions are asymptotically sharp. For prime powers $q$, we also improve the known upper bounds on $c(q,8)$ and $c(q,12)$ by giving new geometric constructions of $q$-regular induced subgraphs in the symplectic generalized quadrangle $\mathsf{W}(3,q)$ and the split Cayley hexagon $\mathsf{H}(q)$, respectively. Our constructions show that \[c(q,8) \le 2(q^3 - q\sqrt{q} - q)\] for $q$ an even power of a prime, and \[c(q, 12) \le 2(q^5 - 3q^3)\] for all prime powers $q$. For $q \in \{3,4,5\}$ we also give a computer classification of all $q$-regular induced subgraphs of the classical generalized quadrangles of order $q$.

description: We investigated cell shape differentiation among Apis florea populations distributed in four states (Hormuzgan-Bushehr-Khuzestan-Ilam states) of Iran using elliptic Fourier analysis (EFA - outline-based geometric morphometric analysis) on all forewing cells. Outline-based analysis was performed on all closed cells on the forewings of 114 A. florea colonies from 13 locations in Iran. According to the statistical analysis of each cell shape, the most efficient cells to discriminate populations were 2nd cubital, 3rd submarginal and marginal cells. Discriminant Function Analysis of Fourier coefficients (FCs) for each cell resulted in two clusters: southern A. florea populations from lower latitude (Hormuzgan state); and the rest of the populations from higher latitude (Ilam, Khuzestan, Bushehr state) with different differential discrimination values (1st submarginal cell = 75.4%, 2nd submarginal cell = 86.0%, 1st medial cell and 2nd medial cell = 86.8%, marginal cell = 88.6%, 3rd submarginal cell = 90.4%, 2nd cubital cell = 92.1%). This study showed that EFA has been functional and effective for distinguishing A. florea populations based on the wing cell shapes. The outline-based geometric morphometric applied in our study has been as successful as the other morphometric approaches such as standard morphometric and landmark-based geometric morphometric in previous studies.

description: Irene worked at the Humber factory on Humber Road, Coventry. She worked in offices before the war, and then when the war broke out, she was sent to work on the production line. She worked a 5 1/2 day week: 47 hours a week, 8-6 Monday to Friday and Saturday morning.The factory took 70 hits during the Coventry Blitz. Irene was in an air raid shelter on King Edward Road in Stoke, Coventry on the night of the Blitz. Irene cycled to work every day, and she saw the Cathedral in ruins and the city destroyed. She had nightmares for years. After the bombing, Irene was told by soldiers to report to the factory; they were given fresh water, bread and milk if they reported. A soldier brought the rubble onto Humber Road. Women, Irene included, washed the rubble and bricks so they could be reused. Irene continued working there until the war ended.Irene received a certificate from the Rootes Group (who owned the factory) in 1945.
Updating the (Supermassive Black Hole Mass) - (Spiral Arm Pitch Angle) Relation: A Strong Correlation for Galaxies with Pseudobulges

description: We have conducted an image analysis of the (current) full sample of 44 spiral galaxies with directly measured supermassive black hole (SMBH) masses, $M_{\rm BH}$, to determine each galaxy's logarithmic spiral arm pitch angle, $ϕ$. For predicting black hole masses, we have derived the relation: $\log({M_{\rm BH}/{\rm M_{\odot}}}) = (7.01\pm0.07) - (0.171\pm0.017)[|ϕ|-15°]$. The total root mean square scatter associated with this relation is 0.43 dex in the $\log{M_{\rm BH}}$ direction, with an intrinsic scatter of $0.33\pm0.08$ dex. The $M_{\rm BH}$-$ϕ$ relation is therefore at least as accurate at predicting SMBH masses in spiral galaxies as the other known relations. By definition, the existence of an $M_{\rm BH}$-$ϕ$ relation demands that the SMBH mass must correlate with the galaxy discs in some manner. Moreover, with the majority of our sample (37 of 44) classified in the literature as having a pseudobulge morphology, we additionally reveal that the SMBH mass correlates with the large-scale spiral pattern and thus the discs of galaxies hosting pseudobulges. Furthermore, given that the $M_{\rm BH}$-$ϕ$ relation is capable of estimating black hole masses in bulge-less spiral galaxies, it therefore has great promise for predicting which galaxies may harbour intermediate-mass black holes (IMBHs, $M_{\rm BH}<10^5$ ${\rm M_{\odot}}$). Extrapolating from the current relation, we predict that galaxies with $|ϕ| \geq 26.7°$ should possess IMBHs.

description: The main purpose of the current study is to analyse how desire, perceived self, social values and involvement are related to consumer engagement in the fashion luxury industry. A sample of 295 fashion luxury consumers participate in the study. Findings suggest that desire is the most significant driver of consumer engagement; subjective well-being (SWB) acts as an outcome of consumer engagement; and past experience has an important role in the relationship between engagement and SWB. The article also provides managerial implications, lists out the limitations of current research and offers scope for further research.

description: In this work, we obtained an approximate bound state solution to Schrodinger with Hulthen plus exponential Coulombic potential with centrifugal potential barrier using parametric Nikiforov-Uvarov method. We obtained both the eigen energy and the wave functions to non -relativistic wave equations. We implement Matlab algorithm to obtained the numerical bound state energies for various values of adjustable screening parameter at various quantum state.. The developed potential reduces to Hulthen potential and the numerical bound state energy conform to that of existing literature.

description: The two-point correlation functions of kaonic viscous stress tensors and electro-magnetic currents have been calculated respectively to estimate the contributions of the strange sector in the shear viscosity and electrical conductivity of hadronic medium. In the one-loop correlators, kaon propagators contain a non-zero thermal width that leads to non-divergent values of transport coefficients. With the help of effective Lagrangian densities of strange hadrons, we have calculated in-medium self-energy of kaon for different possible mesonic loops, whose imaginary part provide the estimation of kaon thermal width. It is observed that near the quark-hadron transition temperature, the contribution of kaons to shear viscosity is larger and increases faster with temperature than pionic contribution. In case of electrical conductivity the trend due kaon component appears to be opposite in nature with respect to pion component.
