description: The characteristic feature of the Kepler Problem is the existence of the so-called Laplace--Runge--Lenz vector which enables a very simple discussion of the properties of the orbit for the problem. It is found that there are many classes of problems, some closely related to the Kepler Problem and others somewhat remote, which share the possession of a conserved vector which plays a significant rôle in the analysis of these problems.

description: A Convolutional Recurrent Neural Network (CRNN) is trained to reproduce the evolution of the spinodal decomposition process in three dimensions as described by the Cahn-Hilliard equation. A specialized, physics-inspired architecture is proven to provide close accordance between the predicted evolutions and the ground truth ones obtained via conventional integration schemes. The method can accurately reproduce the evolution of microstructures not represented in the training set at a fraction of the computational costs. Extremely long-time extrapolation capabilities are achieved, up to reaching the theoretically expected equilibrium state of the system, consisting of a layered, phase-separated morphology, despite the training set containing only relatively-short, initial phases of the evolution. Quantitative accordance with the decay rate of the Free energy is also demonstrated up to the late coarsening stages, proving that this class of Machine Learning approaches can become a new and powerful tool for the long timescale and high throughput simulation of materials, while retaining thermodynamic consistency and high-accuracy.

description: The one-dimensional nearest-neighbor totally asymmetric simple exclusion process can be constructed in the same space as a last-passage percolation model in Z^2. We show that the trajectory of a second class particle in the exclusion process can be linearly mapped into the competition interface between two growing clusters in the last-passage percolation model. Using technology built up for geodesics in percolation, we show that the competition interface converges almost surely to an asymptotic random direction. As a consequence we get a new proof for the strong law of large numbers for the second class particle in the rarefaction fan and describe the distribution of the asymptotic angle of the competition interface.

description: Whilst undertaking observations of trainee design and technology teachers in a variety of settings across the North West of England, we have encountered an increasing rise in the number of schools offering catering as part of a varied and diverse range of curriculum options within the suite of design and technology subjects studied across KS3/KS4 and into KS5. This short article seeks to highlight and celebrate just one of these examples. It looks at the rationale behind the investment in catering as a Key Stage 4 option, both in terms of capital spend (from the point of facilities and rooms) and staffing. Clearly these should be framed against the successes achieved by the young people at the school in question.

description: The theory for single stellar evolution predicts a gap in the mass distribution of black holes (BHs) between approximately 45-130M$_{\odot}$, the so-called "pair-instability mass gap". We examine whether BHs can pollute the gap after accreting from a stellar companion. To this end, we simulate the evolution of isolated binaries using a population synthesis code, where we allow for super-Eddington accretion. Under our most extreme assumptions, we find that at most about 2% of all merging binary BH systems contains a BH with a mass in the pair-instability mass gap, and we find that less than 0.5% of the merging systems has a total mass larger than 90M$_{\odot}$. We find no merging binary BH systems with a total mass exceeding 100M$_{\odot}$. We compare our results to predictions from several dynamical pathways to pair-instability mass gap events and discuss the distinguishable features. We conclude that the classical isolated binary formation scenario will not significantly contribute to the pollution of the pair-instability mass gap. The robustness of the predicted mass gap for the isolated binary channel is promising for the prospective of placing constraints on (i) the relative contribution of different formation channels, (ii) the physics of the progenitors including nuclear reaction rates, and (iii), tentatively, the Hubble parameter.

description: A rich inventory of complex organic molecules (COMs) has been observed in high abundances in the gas phase toward Class 0 protostars. These molecules are suggested to be formed in ices and sublimate in the warm inner envelope close to the protostar. However, only the most abundant COM, methanol (CH3OH), has been firmly detected in ices before the era of James Webb Space Telescope (JWST). Now it is possible to detect the interstellar ices of other COMs and constrain their ice column densities quantitatively. We aim to determine the column densities of several oxygen-bearing COMs (O-COMs) in both gas and ice for two low-mass protostellar sources, NGC 1333 IRAS 2A and B1-c, as case studies in our JWST Observations of Young protoStars (JOYS+) program. By comparing the column density ratios w.r.t. CH3OH between both phases measured in the same sources, we can probe into the evolution of COMs from ice to gas in the early stages of star formation. We are able to fit the fingerprints range of COM ices between 6.8 and 8.8 um in the JWST/MIRI-MRS spectra of B1-c using similar components as recently used for IRAS 2A. We claim detection of CH4, OCN-, HCOO-, HCOOH, CH3CHO, C2H5OH, CH3OCH3, CH3OCHO, and CH3COCH3 in B1-c, and upper limits are estimated for SO2, CH3COOH, and CH3CN. The comparison of O-COM ratios w.r.t CH3OH between ice and gas shows two different cases. 1) the column density ratios of CH3OCHO and CH3OCH3 match well between the two phases, which may be attributed to a direct inheritance from ice to gas or strong chemical links with CH3OH. 2) the ice ratios of CH3CHO and C2H5OH w.r.t. CH3OH are higher than the gas ratios by 1-2 orders of magnitudes. This difference can be explained by the gas-phase reprocessing following sublimation, or different spatial distributions of COMs in the envelope.

(2) to provide the flower farmers with strategies of management improvement and the government officers with policy support direction in order to overcome current difficulties. The Korean floricultural industry with a high income-elasticity has been growing along with national income increase. However real floricultural production in 2001 is expected to decrease due to depressed consumption expectation as a result of the recent economic slowdown. Among this situations, flower exports has increased due to rising exchange rates. developing new sales channels due to sluggish domestic demand. Korea's floricultural exports is primarily targeted to Japan. Meanwhile China's floricultural industry is growing rapidly as the Chinese government is fostering the industry. Therefore, china is expected to rise as a competitor in the Japanese market.

description: Leadership and its culturally preferred style is influenced by national culture. At same time, leaders make influence on corporate culture, trying to create, maintain or change it, in order to improve organizational performance. The leader’s main contribution lies precisely in the management of corporate culture. On the other hand, corporate cultures influence the leaders. It “allowed” to behave on a certain way, make restrictions and exc. In general, corporate culture shapes the behavior of leaders. The critical factor that determines the success of any organization is leadership abilities of its management. National, political and corporate cultures show a high level of diversity at the international level, and predispose the favored type of cultural leaders. GLOBE project results indicate that there is a trend towards convergence of leadership practice, considering that the majority of organizations surveyed are in favor of charismatic or transformational leadership. The new leader is not the authoritarian dictator, or person with unusual charisma. Characteristics of leaders are seen as linked to “soft” skills, person enthusiasm, inspiration, etc... It is certain that the turbulent air, lots of competitors and unexpected everyday pressures, impose that leader has a style with attributes such as inspiration and visionary. New super-transformational leader possesses qualities that can respond to a changing environment. The new leader will always encourage knowledge and creativity of employees, thereby building an organization that continually learns.

description: In the first chapter, co-authored with Dr. Christian Julliard, we study the impact of option expiration on underlying stock volatility. We find a negative direct effect on stock realized volatility and a positive and significant effect on stock implied volatility. Moreover, a positive spillover effect on stocks with no options expiring on a given expiration date is observed. Two possible explanations are discussed, namely investors’ delta hedging and stock pinning around option expiration dates. Both seem to affect stock volatility. Finally, we implement a trading strategy that takes advantage of these findings. The second chapter studies the investment behaviour of mutual funds during financial bubbles. I find that mutual funds over-invest in bubble sectors during the run-up and withdraw money right before the collapse. This result is robust across different benchmark specifications and across fund styles. I also document that this strategy generates a positive and significant alpha (4% on an annual basis), with respect to both a risk-neutral expectation and the Fama-French factors. The paper provides evidence supporting the theory that mutual funds ride the bubble rather than causing it. It also demonstrates that mutual fund holdings can predict the future returns of a sector over a short to medium horizon. Building on the previous findings, the third chapter studies the fee setting behaviour of mutual funds during financial bubbles. It shows that, besides the well-documented persistence of fees, mutual funds charge higher fees during price run-ups. Two theoretical models support the finding: the first shows that investors’ sensitivity to fees decreases during bubble episodes, while the second demonstrates that the increase in fees translates into a higher mark-up over marginal cost.
Josephson frequency of resonantly-coupled atomic and molecular condensates

description: Motivated by recent experiments [Claussen N R et al. 2003 Preprint cond-mat/0302195] we investigate the magnetic-field dependence of the Josephson frequency of coherent atom-molecule oscillations near a Feshbach resonance. Far off resonance this frequency is determined by two-body physics. However, the Josephson frequency is relatively large and a description purely in terms of scattering lengths turns out to be inadequate. In particular, we have to include the effective range parameter of the interatomic interaction in our calculations. Close to resonance, the frequency deviates from the two-body results due to various many-body shifts. Considering also the many-body effects, we find perfect agreement with the experimental results over the entire range of magnetic field.

The first star (TOI-6002) is located $32.038\pm0.019$ pc away, with a radius of $0.2409^{+0.0066}_{-0.0065}$ \rsun, a mass of $0.2105^{+0.0049}_{-0.0048}$ \msun, and an effective temperature of $3229^{+77}_{-57}$ K. The second star (TOI-5713) is located $40.946\pm0.032$ pc away, with a radius of $0.2985^{+0.0073}_{-0.0072}$ \rsun, a mass of $0.2653\pm0.0061$ \msun, and an effective temperature of $3225^{+41}_{-40}$ K. We validated the planets using TESS data, ground-based multi-wavelength photometry from many ground-based facilities, as well as high-resolution AO observations from Keck/NIRC2. TOI-6002 b has a radius of $1.65^{+0.22}_{-0.19}$ \re\ and receives $1.77^{+0.16}_{-0.11} S_\oplus$. TOI-5713 b has a radius of $1.77_{-0.11}^{+0.13} \re$ and receives $2.42\pm{0.11} S_\oplus$. Both planets are located near the radius valley and near the inner edge of the habitable zone of their host stars, which makes them intriguing targets for future studies to understand the formation and evolution of small planets around M-dwarf stars.

description: For graph classes $P_1,...,P_k$, Generalized Graph Coloring is the problem of deciding whether the vertex set of a given graph $G$ can be partitioned into subsets $V_1,...,V_k$ so that $V_j$ induces a graph in the class $P_j$ $(j=1,2,...,k)$. If $P_1 = ... = P_k$ is the class of edgeless graphs, then this problem coincides with the standard vertex $k$-{\sc colorability}, which is known to be NP-complete for any $k\ge 3$. Recently, this result has been generalized by showing that if all $P_i$'s are additive induced-hereditary, then generalized graph coloring is NP-hard, with the only exception of recognising bipartite graphs. Clearly, a similar result follows when all the $P_i$'s are co-additive. In this paper, we study the problem where we have a mixture of additive and co-additive classes, presenting several new results dealing both with NP-hard and polynomial-time solvable instances of the problem.

The Role of Design in Business ROI: A Literature Review
Creators: name: Beausoleil, Angele
Publisher: name: The University of British Columbia
Year: 2012

description: This paper reviews select literature that examines the role of design in shaping, influencing and affecting an organization’s return on investment (ROI). It explores the meaning, context and application of the concept of “design ROI” across disciplines and sectors and provides an analysis of the most recent research on the subject of the economic value and performance of design. The bulk of this paper highlights the authors and organizations currently investing in research and proposing design value metrics. The vast inventory of research and methodologies infers the need for a linguistic typology -- a common and shared vocabulary -- to better communicate design’s positive economic impact across economic and industry sectors. It concludes that good design is good for business and suggests research gaps to better understand the value of design in business. The purpose of this research is to broaden the understanding of the impact of design on business ROI and to present evidence on why design is good for business.

description: Laboratory (laser and Z-pinch) opacity measurements of well-characterized plasmas provide data to assist inertial confinement fusion, astrophysics and atomic-physics research. In order to test the atomic-physics codes devoted to the calculation of radiative properties of hot plasmas, such experiments must fulfill a number of requirements. In this work, we discuss some sources of uncertainty in absorption-spectroscopy experiments, concerning areal mass, background emission, intensity of the backlighter and self-emission of the plasma. We also study the impact of spatial non-uniformities of the sample.

description: For years companies in Serbia have functioned according to non-market principles. This led to a growing imbalance between domestic and market economies. In fact, in modern market economies, and especially in those which seek to build a market, there is a need for timely, adequate and integrated market information. That need caused the development of certain approaches and methods of market research in the function of helping the company managers to solve emerging problems in business for which they lack competences, knowledge and management skills. Accordingly, the aim of this research is to inform the employess in meat processing industry in Serbia about key elements necessary for effective menagement of marketing activities of the company. Check was carried out according to the procedure by which relevant scientific conclusions were reached – by researching data in the field, specifically, by collecting relevant data in companies in meat processing industry in Serbia. Desk research was also carried out with the aim to present certain methodology of market researches to companies in meat processing industry, since, as empirical research shows, marketing activities in most companies are poorly developed. Therefore, successful business of companies in meat processing industry in Serbia requires availability of timely information about changes in the environment, especially on the market, in order to reduce risk and uncertainty.

description: A new density matrix renormalisation group (DMRG) approach is presented for quantum systems of two spatial dimensions. In particular, it is shown that it is possible to create a multi-chain-type 2D DMRG approach which utilises previously determined system and environment blocks {\it at all points}. One firstly builds up effective quasi-1D system and environment blocks of width $L$ and these quasi-1D blocks are then used to as the initial building-blocks of a new 2D infinite-lattice algorithm. This algorithm is found to be competitive with those results of previous 2D DMRG algorithms and also of the best of other approximate methods. An illustration of this is given for the spin-half and spin-one Heisenberg models on the square lattice. The best results for the ground-state energies per bond of the spin-half and spin-one square-lattice Heisenberg antiferromagnets for the $N = 20 \times 20$ lattice using this treatment are given by $E_g/N_B = -0.3321$ and $E_g/N_B = -1.1525$, respectively.

description: Modern business environment has lack of competitive advancement opportunities. Beside innovations in new technologies, other areas have decline in number of fundamentally new products in favor of only cosmetically changed ones. The most of companies are not ones that are developing and producing symbols of current technical and technological revolution, and they are forced to accept and use existing remedies for business improvement, or often, just for survival. New technologies, Internet particularly, set some new business rules that majority of subjects had to accept. Companies that early anticipated importance of Internet facilitation, and was continually accepting innovations in this area, had significant chances to create specific advancement. Shortly, competitive environment and change intensive customer demands, imposed internet utilization as imperative to all that would like to survive on today’s market. As result, today we are not deciding should we use new technologies. Today we are about to decide the extent to which we replace traditional market resorts with e-solutions. This sets relatively such new concept, as Internet marketing is, as subject of consideration in practice as well as in theoretical discussions. Beneficial effects of this concept are especially underlined in area of Customer Relations Management (CRM), and in process of good-relations building with all subjects in chain of value. As number of fields where competitive advantages could be realized, internet marketing and CRM are becoming very important subjects in marketing discussions frame.

description: The recently discovered APt$_3$P (A=Sr,Ca,La) family of superconductors offers a platform to study frequency dependent superconducting phenomena as the electron-phonon coupling varies from weak to strong. Here we perform ab initio Eliashberg theory calculations to investigate two such phenomena, the occurrence of dip-hump structures in the tunneling spectra and the magnetic field induced coexistence of even and odd frequency superconductivity in these compounds. By calculating the superfluid density, we make predictions for the occurrence of the paramagnetic Meissner effect as a hallmark of odd frequency pairing. Our results provide a link between two seemingly uncorrelated aspects of even and odd frequency superconductivity and provide theoretical guidance for the experimental identification of bulk odd frequency superconductivity in this material's family.

description: We analyze the electrostatic self-energy of a point like electrically charged particle induced by a cosmic string in the context of gravity's rainbow, as well the electrostatic self-force on this particle. The possibility of the solution associated with a charged particle to be altered by modifications in dispersion relations of the space-time is discussed. We show that the self-energy depends on the rainbow functions and that this quantity can either increase or decrease depending on the rainbow function chosen, as compared with analogous result in the framework of general relativity. With respect to the self-force, its dependence with the rainbow functions is also pointed out

description: Properties of non-canonical GC Base Pairs and their relation with mechanochemical cleavage of DNA are analyzed. A hypothesis of the involvement of the Transient GC Wobble Base Pairs in the mechanisms of the mechanochemical cleavage of DNA and epigenetic mechanisms with participation of 5-methylcytosine is proposed. The hypothesis explains the increase in the frequency of the breaks of the sugar-phosphate backbone of DNA after cytosines, asymmetric character of these breaks, and an increase in the frequency of breaks in CpG after cytosine methylation.

description: The energy spectra of two different quantum systems are paired through supersymmetric algorithms. One of the systems is Hermitian and the other is characterized by a complex-valued potential, both of them with only real eigenvalues in their spectrum. The superpotential that links these systems is complex-valued, parameterized by the solutions of the Ermakov equation, and may be expressed either in nonlinear form or as the logarithmic derivative of a properly chosen complex-valued function. The non-Hermitian systems can be constructed to be either parity-time-symmetric or non-parity-time-symmetric.

description: We experimentally study electron transport across a single planar junction between the indium electrode and MnTe altermagnet candidate. We confirm standard Ohmic behavior with strictly linear current-voltage curves above the indium critical field or temperature, although with high, about 100~kOhm, junction resistance. At low temperatures and in zero magnetic field, we observe a well-developed Andreev curve with the pronounced coherence peaks, which cannot be normally expected for these high values of normal junction resistance. The conclusion on the Andreev reflection is also supported by suppression in magnetic field, as well as by universality of the observed behavior for all of the investigated samples. The experimental results can be explained by specifics of Andreev transport through the disordered region at the superconductor-altermagnet interface. Due to a different set of restrictions on the possibility of Andreev reflection, an altermagnet suffers from the presence of disorder less than a normal spin-degenerate metal, so the conductance enhancement is retained throughout the superconducting gap.

On the propagation of non stationary pressure waves in stellar interiors
Creators: name: Mach, Patryk
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: An analysis of the propagation of non stationary waves in the adiabatic region of stellar interior is presented. An equation of motion with an effective potential is derived, similar to the Zerilli equation known in the propagation of gravitational waves. The Huyghens principle is violated in this case and the energy diffusion outward null cones is expected. Numerical calculations demonstrate that the diffusion is weak for the case of standard Solar model; thus no significant effect corresponding to quasinormal modes can be expected. The likely reason for the absence of stronger features is the restriction of our analysis to adiabatic regions only, where the breakdown of the Huyghens principle is insignificant.

Chromo-natural inflation supported by enhanced friction from Horndeski gravity

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We study the extension of the chromo-natural inflation model by incorporating nonminimal coupling between the axion field and gravity. Nonminimal coupling is introduced so that it enhances friction in the axion's equation of motion and thus supports slow-roll inflation. This enhanced friction effectively delays the activation of the gauge field, thereby preventing the overproduction of gravitational waves in the CMB scale. We extend previous results by describing the nonminimal coupling in a general and unifying way utilizing Horndeski gravity. This allows us to explore systematically and comprehensively possible enhanced friction models of chromo-natural inflation consistent with observations. We find a novel enhanced friction model that shows better agreement (within 1$σ$) with CMB measurements than the previous nonminimally coupled chromo-natural inflation model. The gravitational-wave spectrum starts to rise at some wavenumber due to retarded activation of the gauge field in the late stage of inflation. We show how one can identify the wavenumber at which this occurs based on the background evolution and present a universal analytic formula for the gravitational-wave spectrum that can be used for any enhanced friction model of chromo-natural inflation.
