description: The properties of wind accretion in symbiotic X-ray binaries (SyXBs) consisting of red-giant and magnetized neutron star (NS) are discussed. The spin-up/spin-down torques applied to NS are derived based on a hydrodynamic theory of quasi-spherical accretion onto magnetized NSs. In this model, a settling subsonic accretion proceeds through a hot shell formed around the NS magnetosphere. The accretion rate onto the NS is determined by the ability of the plasma to enter the magnetosphere.Due to large Reynolds numbers in the shell, the interaction of the rotating magnetosphere with plasma initiates a subsonic turbulence. The convective motions are capable of carrying the angular momentum through the shell. We carry out a population synthesis of SyXBs in the Galaxy with account for the spin evolution of magnetized NS. The Galactic number of SyXBs with bright (M_v<1) low-mass red-giant companion is found to be from \sim 40 to 120, and their birthrate is \sim 5\times 10^{-5}-10^{-4} per year. According to our model, among known SyXBs, Sct X-1 and IRXS J180431.1-273932 are wind-fed accretors. GX 1+4 lies in the transition from the wind-fed SyXBs to SyXBs in which the giants overflow their Roche lobe. The model successfully reproduces very long NS spins (such as in IGR J16358-4724 and 4U 1954+31) without the need to invoke very strong magnetic fields.

description: Ця стаття присвячена вивченню застосування технології блокчейн у фінансовій сфері. Застосування технології блокчейн на фінансових ринках привертає все більше уваги з боку теоретичних кіл і практиків. Це пов’язано з тим, що технологія має багато переваг, які можуть значно оптимізувати процеси фінансового посередництва та вирішити ключові проблеми у відносинах на фінансовому ринку, а саме асиметрію інформації та зростання транзакційних витрат. Метою статті є дослідження сильних і слабких сторін української економіки. На поточному етапі розвитку фінансового ринку технологія блокчейн має величезний потенціал і швидко впроваджується. Основними проблемами впровадження технології блокчейн на фінансових ринках є: недостатня окупність інвестицій в технологію, відсутність чіткого нагляду і стандартизації, єдине ставлення регулюючих органів фінансового ринку до технології блокчейн, гарантія конфіденційності даних, проблеми з шифруванням і т. ін. Незважаючи на потенціал блокчейна, у нього також є свої ризики і проблеми. Одним із найбільших ризиків є безпека даних. Блокчейн захищає дані від змін, але не завжди забезпечує конфіденційність. Існують також випадки, коли зловмисники можуть зламати блокчейн. Інша проблема полягає в тому, що блокчейн ще не є повністю зрілою технологією і потребує подальшого розвитку та вдосконалення. Деякі проблеми, такі як масштабування та взаємодія зі старими системами, ще не вирішені. Держава повинна відігравати важливу роль у розробці та впровадженні технології блокчейн. Темпи технологічного розвитку і його входження в соціально-економічні процеси настільки високі, що нормативні акти і спеціальні положення можуть представляти певну загрозу для країни, якщо не буде отримана належна реакція через встановлення стандартів і загальних правил використання. Ця проблема особливо актуальна для фінансового сектора, де, наприклад, поява «спеціальних» валют може зробити істотний негативний вплив на фінансову стабільність країни. Швидкий розвиток технологій диктує необхідність подальших досліджень. Перспективою подальших досліджень у цьому контексті може бути застосування технологій у сфері державного управління.

description: We discuss how we formulate time evolution of physical quantities in the framework of the Rigged QED (Quantum Electrodynamics). The Rigged QED is a theory which has been proposed to treat dynamics of electrons, photons and atomic nuclei in atomic and molecular systems in a quantum field theoretic way. To solve the dynamics in the Rigged QED, we need different techniques from those developed for the conventional QED. As a first step toward this issue, we propose a procedure to expand the Dirac field operator, which represents electrons, by the electron annihilation/creation operators and solutions of the Dirac equation for electrons in nuclear potential. Similarly, the Schrodinger field operators, which represent atomic nuclei, are expanded by nucleus annihilation/creation operators. Then we derive time evolution equations for these annihilation and creation operators and discuss how time evolution of the operators for physical quantities can be calculated. In the end, we propose a method to approximate the evolution equations of the operators by the evolution equations for the density matrices of electrons and atomic nuclei. Under this approximation, we carry out numerical simulation of the time evolution of electron charge density of a hydrogen atom.

description: The American Samoa longline fishery continues to experience challenging conditions. Catch of the primary target species, albacore tuna has remained at a fairly low levels in comparison with long term averages. Catches of many other marketable species also remained relatively low during the first quarter of 2013, as they were throughout the previous year. However, increasing catches of low-volume-higher priced species, such as mahimahi and yellowfin tuna, may indicate an adaptation of the fishery to supply local demand through local fresh-fish markets. A summary of the fishery’s catch and effort statistics for the first quarter of 2013, based on date of haul, is provided in Table 1. This table was derived from all logbook data submitted to the American Samoa Department of Marine and Wildlife Resources by the first quarter posting date (June 25, 2013). We believe that Table 1 reflects data from 100% of sets made during this quarter by all longline vessels. Only large (>50ft in length) vessels participated in the fishery.

description: NGC 6369 is a double-shell planetary nebula (PN) consisting of a bright annular inner shell with faint bipolar extensions and a filamentary envelope. We have used ground- and space-based narrow-band optical and near-IR images, broad-band mid-IR images, optical long-slit echelle spectra, and mid-IR spectra to investigate its physical structure. These observations indicate that the inner shell of NGC 6369 can be described as a barrel-like structure shape with polar bubble-like protrusions, and reveal evidence for H2 and strong polycyclic aromatic hydrocarbons (PAHs) emission from a photo-dissociative region (PDR) with molecular inclusions located outside the bright inner shell. High-resolution HST narrow-band images reveal an intricate excitation structure of the inner shell and a system of "cometary" knots. The knotty appearance of the envelope, the lack of kinematical evidence for shell expansion and the apparent presence of emission from ionized material outside the PDR makes us suggest that the envelope of NGC 6369 is not a real shell, but a flattened structure at its equatorial regions. We report the discovery of irregular knots and blobs of diffuse emission in low-excitation and molecular line emission that are located up to 80" from the central star, well outside the main nebular shells. We also show that the filaments associated to the polar protrusions have spatial extents consistent with post-shock cooling regimes, and likely represent regions of interaction of these structures with surrounding material.

description: We present the results of a study of selection criteria to identify Type Ia supernovae photometrically in a simulated mixed sample of Type Ia supernovae and core collapse supernovae. The simulated sample is a mockup of the expected results of the Dark Energy Survey. Fits to the MLCS2k2 and SALT2 Type Ia supernova models are compared and used to help separate the Type Ia supernovae from the core collapse sample. The Dark Energy Task Force Figure of Merit (modified to include core collapse supernovae systematics) is used to discriminate among the various selection criteria. This study of varying selection cuts for Type Ia supernova candidates is the first to evaluate core collapse contamination using the Figure of Merit. Different factors that contribute to the Figure of Merit are detailed. With our analysis methods, both SALT2 and MLCS2k2 Figures of Merit improve with tighter selection cuts and higher purities, peaking at 98% purity.

Elucidation Of The Interactome Of G Protein Coupled Receptors In Hypothalamic Weight Regulation
Creators: name: Biebermann, Heike
Publisher: name: Zenodo
Year: 2015

description: Over the last decades obesity has become one of the mayor health burdens worldwide and the development of highly efficient drugs is of utmost importance. More than 40 different G-protein coupled receptors (GPCR) are expressed in different hypothalamic nuclei. They are essentially involved in regulation of food intake, body weight regulation and energy homeostasis, however, their detailed functions and impact on metabolism is not yet understood. So far targeting hypothalamic GPCRs in humans is not very satisfactory as drugs only lead to weight-loss of approximately 10 percent of body weight and have several side effects. One reason for side effects and the partial ineffectiveness might be that pharmacological interventions at one targeted GPCR should also affect interacting and therefore, functionally linked protein(s). Unfortunately, recognition of the full repertoire of interacting partners of GPCRs is not yet unraveled in the entirety. To determine new interacting partners for hypothalamic GPCRs we developed a hypothalamic library screen based on bimolecular fluorescence complementation. By screening for interaction partners of the melanocortin 3 and 4 receptor (MC3R and MC4R) we identified a variety of unexpected potential interactions (transmembrane and cytosolic proteins) that could link these receptors to e.g. glucose metabolism and inflammation on a molecular level. Several of these new interaction partners were confirmed by further experimental approaches and functional consequences of interaction were determined. Strikingly, we could demonstrate in vitro that the functionality of MC4R and MC3R is modulated indeed by so far unknown interacting proteins. Our study clearly points to a potentially much higher complexity of the melanocortin system in energy metabolism then previously assumed. We suggest that this has to be taken into consideration when targeting melanocortin receptors to combat obesity. Finally, under these aspects functional insights into GPCRs should be generally considered as incomplete and not be extrapolated easily to in vivo systems or pathophysiological situations without knowledge of specific interacting proteins.
Multicolor Fluorescent Biosensors For Multiplexed Detection Of Gpcr Receptor Activation
Creators: name: Isbaal Ramos
Publisher: name: Zenodo
Year: 2015

description: We describe a new live-cell assay that uses fluorescent biosensors co-expressed with several GPCRs for measuring the second messenger concentration changes and receptor internalization that occurs after GPCR activation. The molecular structure of the Biosensors comprises: a membrane localization peptide, a second messenger transduction protein binding peptide, a reticulum retention signal and a fluorescent peptide. The biosensors are normally localized in the Plasma Membrane but an increase in the second messenger concentration leads to a change in the structural folding of the Biosensor that promotes its vesicularization. The second messenger transduction protein binding peptide could be replaced depending on the second messenger, resulting three different versions of the biosensors: cAMP; Calcium and DAG Nomad Biosensor. In addition, we also present here the development of multiplexed assays using the different versions of the Biosensor enabling the analysis both different intracellular signaling and receptor internalization, simultaneously.
Adenosine Receptors As A Target In Colonic Inflammation
Creators: name: Nieber, Karen
Publisher: name: Zenodo
Year: 2015

description: The purine nucleoside adenosine, which is involved in several physiological functions, regulates a wide variety of immune and inflammatory responses and acts as modulator of gut functions. Although it is present at low concentrations in the extracellular space, stressful conditions, such as inflammation, can markedly increase its extracellular level up to micromolar range. Recent evidence suggests a prominent role of A2Areceptors (A2AR) and A2B receptors (A2BR) in the pathophysiology of inflammation (Sitkovsky and Lukashev 2005, Palmer and Trevethick 2008). In the current study we investigated the role of A2AR and A2BR to regulate contractility in untreated and inflamed rat colon preparations using specific receptor agonists and antagonists.
Inflammation was induced by intraluminal instillation of 2,4,6-trinitrobenzenesulfonic acid (TNBS, 0.01/0.1M, 30min). mRNA-expression was determined using RT-PCR. Contractions were measured isometrically in an organbath setup. All four adenosine receptor subtypes were expressed in untreated colon preparations. Activation of A1, A2B, and A3 receptor with specific agonists reduced the acetylcholine (ACh, 10?M)-induced contractions, while activation of A2BR enhanced. After incubation with TNBS morphologically damages in colonic mucosa and muscle walls were detectable followed by reduced ACh-contractions. The TNBS-mediated decrease of ACh-contractions as well as the morphological damages were partially normalized by co-incubation of TNBS with the A2AR agonist 2-p-[carboxyethyl]phenethylamino-5'-N-ethylcarboxamido-adenosine (CGS 21680, 10?M) or the A2BR antagonist 4-(2,3,6,7-tetrahydro-2,6-dioxo-1-propyl-1H-purin-8-yl-benzenesulfonic acid
(PSB 1115, 100?M).
In this study using an in-vitro inflammatory model, we demonstrate that the A2AR agonist CGS 21680 or the A2BR antagonist PSB 1115 effectively conteracted the development of TNBS-induced disturbances in colon preparations, so qualifying adenosine receptors as potential targets in colonic inflammation.

description: Recent searches performed by the CDF and D0 collaborations at the Tevatron for diboson production in final states containing heavy-flavor jets are reported. The searches for WZ and ZZ can be regarded as the ultimate benchmark for the corresponding searches for a low-mass Higgs boson in the WH and ZH final states. Using the exact same techniques as for those Higgs boson searches, the D0 collaboration measured a cross section for WZ/ZZ production of 1.13 +/- 0.36 times its expectation in the standard model, with a diboson signal significance of 3.3 standard deviations (2.9 expected).

description: We consider a graphene sheet in the presence of a strong perpendicular magnetic field with a single short-range delta-impurity situated at one of the carbon sites. We study the neutral inter-Landau level collective excitations, magnetoplasmons, which become localized on the impurity. Some of these excitations involve a pseudospin flip (intervalley transitions), since the impurity can scatter electrons between the two valleys. We propose a classification of states of the excitations in graphene and introduce the appropriate quantum numbers. The energies and optical strengths of collective excitations are calculated for a range of integer filling factors and impurity strengths. We establish a set of symmetries matching the energies and absorption strengths of collective excitations for different sublattice locations of the impurity, filling factors, circular light polarizations and signs of the impurity potential.

description: Several indices that measure the degree of balance of a rooted phylogenetic tree have been proposed so far in the literature. In this work we define and study a new index of this kind, which we call the total cophenetic index: the sum, over all pairs of different leaves, of the depth of their least common ancestor. This index makes sense for arbitrary trees, can be computed in linear time and it has a larger range of values and a greater resolution power than other indices like Colless' or Sackin's. We compute its maximum and minimum values for arbitrary and binary trees, as well as exact formulas for its expected value for binary trees under the Yule and the uniform models of evolution. As a byproduct of this study, we obtain an exact formula for the expected value of the Sackin index under the uniform model, a result that seems to be new in the literature.

description: Self-gravity becomes competitive as an angular momentum transport process in accretion discs at large radii, where the temperature is low enough that external irradiation likely contributes to the thermal balance. Irradiation is known to weaken the strength of disc self-gravity, and can suppress it entirely if the disc is maintained above the threshold for linear instability. However, its impact on the susceptibility of the disc to fragmentation is less clear. We use two-dimensional numerical simulations to investigate the evolution of self-gravitating discs as a function of the local cooling time and strength of irradiation. In the regime where the disc does not fragment, we show that local thermal equilibrium continues to determine the stress - which can be represented as an effective viscous alpha - out to very long cooling times (at least 240 dynamical times). In this regime, the power spectrum of the perturbations is uniquely set by the effective viscous alpha and not by the cooling rate. Fragmentation occurs for cooling times tau < beta_crit / Omega, where beta_crit is a weak function of the level of irradiation. We find that beta_crit declines by approximately a factor of two, as irradiation is increased from zero up to the level where instability is almost quenched. The numerical results imply that irradiation cannot generally avert fragmentation of self-gravitating discs at large radii; if other angular momentum transport sources are weak mass will build up until self-gravity sets in, and fragmentation will ensue.

description: We investigate the effect of the Plume/Interplume Lane (PIPL) structure of the solar Polar Coronal Hole (PCH) on the propagation characteristics of ion-cyclotron waves (ICW). The gradients of physical parameters determined by SOHO and TRACE satellites both parallel and perpendicular to the magnetic field are considered with the aim of determining how the efficiency of the ICR process varies along the PIPL structure of PCH. We construct a model based on the kinetic theory by using quasi-linear approximation. We solve the Vlasov equation for O VI ions and obtain the dispersion relation of ICW. The resonance process in the interplume lanes is much more effective than in the plumes, agreeing with the observations which show the source of fast solar wind is interplume lanes. The solution of the Vlasov equation in PIPL structure of PCH, the physical parameters of which display gradients along and perpendicular direction to the external magnetic field, is thus obtained in a more general form than the previous investigations.

description: We study the dynamics of systems on networks from a linear algebraic perspective. The control theoretic concept of controllability describes the set of states that can be reached for these systems. Under appropriate conditions, there is a connection between the quantum (Lie theoretic) property of controllability and the linear systems (Kalman) controllability condition. We investigate how the graph theoretic concept of a zero forcing set impacts the controllability property. In particular, we prove that if a set of vertices is a zero forcing set, the associated dynamical system is controllable. The results open up the possibility of further exploiting the analogy between networks, linear control systems theory, and quantum systems Lie algebraic theory. This study is motivated by several quantum systems currently under study, including continuous quantum walks modeling transport phenomena. Additionally, it proposes zero forcing as a new notion in the analysis of complex networks.

description: The process of determining the number and characteristics of sources in astronomical images is so fundamental to a large range of astronomical problems that it is perhaps surprising that no standard procedure has ever been defined that has well understood properties with a high degree of statistical rigour on completeness and reliability. There are now a large number of commonly used software tools for accomplishing this task, typically with different tools being used for images acquired using different technologies. Despite this, there have been relatively few quantitative analyses of the robustness or reliability of individual tools, or the details of the techniques they implement. We have an opportunity to redress this omission in the context of surveys planned with the Australian Square Kilometre Array Pathfinder (ASKAP). The Evolutionary Map of the Universe (EMU) survey with ASKAP, a continuum survey of the Southern Hemisphere up to declination +30 deg, aims to utilise an automated source identification and measurement approach that is demonstrably optimal, to maximise the reliability, utility and robustness of the resulting radio source catalogues. A key stage in source extraction methods is the background estimation (background level and noise level) and the choice of a threshold high enough to reject false sources yet not so high that the catalogues are significantly incomplete. In this analysis we present results from testing such algorithms as implemented in the SExtractor, Selavy (Duchamp), and sfind tools on simulated data. In particular the effects of background estimation, threshold and false-discovery rate settings are explored. For parameters that give similar completeness, the false-discovery rate method employed by sfind results in a more reliable catalogue compared to the peak threshold methods of SExtractor and Selavy.

description: We measured the electronic-structure of FeSe_xTe_1-x above and below Tc. In the normal state we find multiple bands with remarkably small values for the Fermi energy, E_F. Yet,below Tc we find a superconducting gap, Delta, that is comparable in size to E_F, leading to a ratio Delta/E_F~0.5 that is much larger than found in any previously studied superconductor. We also observe an anomalous dispersion of the coherence peak which is very similar to the dispersion found in cold Fermi-gas experiments and which is consistent with the predictions of the BCS-BEC crossover theory.

description: We calculate the masses and the strong decays of orbitally excited states $B_{s0}$, $B'_{s1}$, $B_{s1}$ and $B_{s2}$ by the improved Bethe-Salpeter method. The predicted masses of $B_{s0}$ and $B'_{s1}$ are $M_{B_{s0}}=5.723\pm0.280 {\rm GeV}$, $M_{B'_{s1}}=5.774\pm0.330 {\rm GeV}$. We calculate the isospin symmetry violating decay processes $B_{s0}\to B_s π$ and $B'_{s1}\to B_s^* π$ through $π^0-η$ mixing and get small widths. Considering the uncertainties of the masses, for $B_{s0}$ and $B'_{s1}$, we also calculate the OZI allowed decay channels: $B_{s0}\to B\bar K$ and $B'_{s1}\to B^*\bar K$. For $B_{s1}$ and $B_{s2}$, the OZI allowed decay channels $B_{s1}\to B^{*}\bar K$, $B_{s2}\to B\bar K$ and $B_{s2}\to B^{*}\bar K$ are studied. In all the decay channels, the reduction formula, PCAC relation and low energy theorem are used to estimate the decay widths. We also obtain the strong coupling constants $G_{B_{s0}B_sπ}$, $G_{B_{s0}B\bar K}$, $G_{B'_{s1}B_s^*π}$, $F_{B'_{s1}B_s^*π}$, $G_{B'_{s1}B^*\bar K}$, $F_{B'_{s1}B^*\bar K}$, $G_{B_{s1}B^{*}\bar K}$, $F_{B_{s1}B^{*}\bar K}$, $G_{B_{s2}B\bar K}$ and $G_{B_{s2}B^{*}\bar K}$.

description: We derive limits on the interactions of dark matter with quarks from ATLAS null searches for jets + missing energy based on ~1 fb^-1 of integrated luminosity, using a model-insensitive effective theory framework. We find that the new limits from the LHC significantly extend limits previously derived from CDF data at the Tevatron. Translated into the parameter space of direct searches, these limits are particularly effective for ~GeV mass WIMPs. Our limits indicate tension with isospin violating models satisfying minimal flavor violation which attempt to reconcile the purported CoGeNT excess with Xenon-100, indicating that either a light mediator or nontrivial flavor structure for the dark sector is necessary for a viable reconciliation of CoGeNT with Xenon.

description: For the last 4 years, the authors have been investigating the performance in practice of a range of sustainable commercial and institutional buildings worldwide. These investigations involved the principal author in one or more visits to each of the buildings and the personal distribution and collection of a questionnaire survey seeking users perceptions (on a 7-point scale) of a range of factors: operational, environmental, personal control and satisfaction. For this article, the authors focus on users perceptions of the quality of lighting in their work areas. The users overall perceptions of lighting conditions are presented and analysed, first with an overview of the average scores for each question, followed by a look at the shapes of their distributions over the set of buildings and then the results of some correlations between lighting overall and a number of other key performance factors such as health, productivity and overall comfort. It was found that lighting overall was one of the higher scoring factors of the environmental category, and the average scores for the amount of natural and artificial lighting were close to the ideal. However, direct glare from the lights and from the sun and sky were noted as issues to be addressed. © 2012 Taylor & Francis.
On the role of moist and dry processes for atmospheric blocking biases in the Euro-Atlantic region in CMIP6

description: Synoptic- and large-scale features such as extratropical cyclones, Rossby wave packets, and atmospheric blocking modulate the mid-latitude weather and climate. However, several studies have shown strong biases in the frequency of these features in state-of-the-art global climate models. One notable and persistent bias is an underestimation of the atmospheric blocking frequency in the Euro-Atlantic region. In this study, we validate the representation of synoptic- and large-scale features of the North Atlantic flow in eight climate models of the Coupled Model Intercomparison Project 6 (CMIP6), taking the ERA5 reanalysis as a reference. Validation includes atmospheric blocking, storm tracks, eddy heat and moisture fluxes, and warm conveyor belts (WCBs). The selected CMIP6 models underestimate the atmospheric blocking frequency over the eastern North Atlantic and Europe in winter (December to February) by up to 80 %. The frequency biases result from combined biases at different spatial and temporal scales described in the following. First, we define the background flow as the most frequent value of the latitudinal gradient of the geopotential at 500 hPa. In the CMIP6 models, the strongest latitudinal geopotential gradients are equatorward shifted in the North Atlantic basin. This shift favours more zonal and stronger winds to the south of the climatological jet. The differences in the background flow affect Rossby wave breaking and blocking onset and persistence, as illustrated by analysing the eddies in the Euro-Atlantic region. We find an equatorward shift in the eddies in CMIP6 that accelerates the mean flow in the exit region of the Atlantic jet, as indicated by a reduction of the divergence of E-Vectors. The shift in the eddies leads to a less diffluent flow in the east Atlantic and, thus, a less favourable flow for blocking formation. Second, we find a negative bias in WCB outflow frequency in the CMIP6 models in the North Atlantic. Reduced WCB outflow indicates weaker transport of low potential vorticity (PV) from the lower to the upper troposphere by moist diabatic processes and consequently weaker downstream ridge amplification and, therefore, a less diffluent flow over the eastern Atlantic and weaker diabatic contributions to blocking. The negative WCB outflow bias can be linked to an underestimation of the meridional moisture transport at low levels in the climatological WCB inflow area in the western Atlantic. Thus, the misrepresentation of moist processes contributes to the negative blocking biases. Accordingly, an improved representation of the moist processes in the next generation of climate models could improve the blocking representation.

description: The American Samoa longline fishery continues to experience challenging conditions. Catch of the primary target species, albacore tuna has remained at a fairly low level in comparison with long term averages. Catches of many other marketable species were also relatively low during the second quarter of 2013, as they were throughout 2012. However, increasing catches of low-volume-higher-priced species, yellowfin tuna and wahoo, may indicate an adaptation of the fishery to supply local demand through local fresh-fish markets. Table 1 provides a summary of the fishery’s catch and effort statistics for the second quarter of 2013, based on date of haul. The table was derived from all logbook data submitted to the American Samoa Department of Marine and Wildlife Resources by the second quarter posting date (September 25, 2013). We believe the data in Table 1 include 100% of the sets made during the second quarter. Only large (>50 ft in length) longline vessels participated in the fishery.

description: An edge-coloring of a multigraph G with colors 1,2,...,t is called an interval t-coloring if all colors are used, and the colors of edges incident to any vertex of G are distinct and form an interval of integers. In this paper we prove that if G is a connected cubic multigraph (a connected cubic graph) that admits an interval t-coloring, then t\leq |V(G)| +1 (t\leq |V(G)|), where V(G) is the set of vertices of G. Moreover, if G is a connected cubic graph, G\neq K_{4}, and G has an interval t-coloring, then t\leq |V(G)| -1. We also show that these upper bounds are sharp. Finally, we prove that if G is a bipartite subcubic multigraph, then G has an interval edge-coloring with no more than four colors.

description: In a previous paper [Phys.Rev.E 83, 051911] we have shown that the results of a quantum-mechanical calculation of electronic energy transfer (EET) over aggregates of coupled monomers can be described also by a model of interacting classical electric dipoles in a weak-coupling approximation, which we referred to as the realistic coupling approximation (RCA). The method was illustrated by EET on a simple linear chain of molecules and also by energy transfer on the Fenna-Matthews-Olson (FMO) complex relevant for photosynthesis. The study was limited to electronic degrees of freedom since this is the origin of coherent EET in the quantum case. Nevertheless, more realistic models of EET require the inclusion of the de-cohering effects of coupling to an environment, when the molecular aggregate becomes an open quantum system. Here we consider the quantum description of EET on a linear chain and on the FMO complex, incorporating environment coupling and construct the classical version of the same systems in the density matrix formalism. The close agreement of the exact quantum and exact classical results in the RCA is demonstrated and justified analytically. This lends further support to the conclusion that the coherence properties of EET in the FMO complex is evident at the classical level and should not be ascribed as solely due to quantum effects.
