description: In his work on singularities, expanders and topology of maps, Gromov showed, using isoperimetric inequalities in graded algebras, that every real valued map on the $n$-torus admits a fibre whose homological size is bounded below by some universal constant depending on $n$. He obtained similar estimates for maps with values in finite dimensional complexes, by a Lusternik--Schnirelmann type argument. We describe a new homological filling technique which enables us to derive sharp lower bounds in these theorems in certain situations. This partly realizes a programme envisaged by Gromov. In contrast to previous approaches our methods imply similar lower bounds for maps defined on products of higher dimensional spheres.

description: Bayesian analysis often concerns an evaluation of models with different dimensionality as is necessary in, for example, model selection or mixture models. To facilitate this evaluation, transdimensional Markov chain Monte Carlo (MCMC) relies on sampling a discrete indexing variable to estimate the posterior model probabilities. However, little attention has been paid to the precision of these estimates. If only few switches occur between the models in the transdimensional MCMC output, precision may be low and assessment based on the assumption of independent samples misleading. Here, we propose a new method to estimate the precision based on the observed transition matrix of the model-indexing variable. Assuming a first order Markov model, the method samples from the posterior of the stationary distribution. This allows assessment of the uncertainty in the estimated posterior model probabilities, model ranks, and Bayes factors. Moreover, the method provides an estimate for the effective sample size of the MCMC output. In two model-selection examples, we show that the proposed approach provides a good assessment of the uncertainty associated with the estimated posterior model probabilities.

Subjects: Marketing management (incl. strategy and customer relations)

description: Retailing is the largest private industry in the world. It is also India's largest industry accounting for over 10% of the country's GDP and around 8% of the employment. Customer relationship management is an emerging tool that enables marketers to maintain their presence in the dynamic marketing environment. In the city like Udaipur these organized retail store and firms are concentrating and targeting the consumer from the different segments like rural. urban, low, middle and high income segments etc. The research paper attempts to evaluate the CRM practices of the retail stores in Udaipur city. CRM is highly exercised in the industry like hospitality, services industry etc, but it is having equal importance in the retail industry also The results of this research paper shows that the customers don't take a single second when it comes to change the preference and break the loyalty for an organization, in such a situation it the CRM of the organization which will compel the customers to visit the retail outlet again and again. CRM is accepted and practised as the most effective tool of marketing to retain customers. It involves the commitment of the organisation to align its people, process and technology to serve the customers. This research paper is intended to find the relevance of CRM as a tool for maintaining and retaining customers in Indian retail sector.

description: WITH all the aplomb that made our forefathers draw a military parallel, old Fuller of The Worthies of England remarked that the scouts of Charles, Duke of Burgundy, who mistook a field full of high thistles for the army of the King of France with their lances held upright, might have been pardoned for the like mistake about the plenteous beans of Leicestershire where, especially about Barton-in-the-Beans, they looked like a forest at harvest. He emphasises the county's prolificacy in this pulse by a reference to the nickname 'Bean-belly Leicestershire', and to the neighbouring men's quip, 'Shake a Leicestershire yeoman by the collar, and you shall hear the beans rattle in his belly', which the Leicester men answered by rattling the silver in their pockets.

description: In this paper, we study a circle action on a compact oriented manifold with a discrete fixed point set. The fixed point data consists of the weights of the $S^1$-representations at the fixed points. We prove various results and properties of the action, in terms of the fixed point data. We show that the manifold can be described by a multigraph associated to it. Specializing into the case of dimension 4, we classify the fixed point data. Moreover, we prove that there exist oriented $S^1$-manifolds with these fixed point data. Finally, we show that a certain multigraph behaves like a manifold.

description: Quantum coherence and quantum correlations are of fundamental and practical significance for the development of quantum mechanics.They are also cornerstones of quantum computation and quantum communication theory. Searching physically meaningful and mathematically rigorous quantifiers of them are long-standing concerns of the community of quantum information science, and various faithful measures have been introduced so far. We review in this paper the measures of discordlike quantum correlations for bipartite and multipartite systems, the measures of quantum coherence for any single quantum system, and their relationship in different settings. Our aim is to provide a full review about the resource theory of quantum coherence, including its application in many-body systems, and the discordlike quantum correlations which were defined based on the various distance measures of states. We discuss the interrelations between quantum coherence and quantum correlations established in an operational way, and the fundamental characteristics of quantum coherence such as their complementarity under different basis sets, their duality with path information of an interference experiment, their distillation and dilution under different operations, and some new viewpoints of the superiority of the quantum algorithms from the perspective of quantum coherence. Additionally, we review properties of geometric quantum correlations and quantum coherence under noisy quantum channels. Finally, the main progresses for the study of quantum correlations and quantum coherence in the relativistic settings are reviewed. All these results provide an overview for the conceptual implications and basic connections of quantum coherence, quantum correlations, and their potential applications in various related subjects of physics.

description: Sir William Herrick (1562-1653) bought Beaumanor in Woodhouse from the Earl of Essex in 1595. The youngest son of John Herrick, a former mayor of Leicester, he had been apprenticed to his brother Nicholas, a goldsmith of London. After his brother's death he set up in business for himself and eventually became James I's jeweller. He was also appointed one of the Tellers of the Exchequer by James I and carried off some of the papers of that office when he retired. He married Joan May, a daughter of Richard May, a citizen and Merchant Taylor of London. Her father was the son of an English merchant who settled in Portugal during the first half of the sixteenth century and married there. Being a younger son he was sent back to England, obtained letters of naturalisation as an insurance against his foreign birth, and became a successful merchant. He eventually retired to Rawmere in Sussex, a house and manor in Lavant parish, which he had bought in 1581. The family lived there until it was sold to the Duke of Richmond in the eighteenth century.

description: St. Bartholomew's Day 1662 marks the foundation of many Nonconformist chapels in the county because on that day many ministers were ejected from their benefices foc refusing to subscribe to the newly-revised Book of Common Prayer. Not all of them were ministers intruded by the Parliamentary commissioners during the Civil War or appointed by the Lord Protector or private patrons during the Commonwealth. Some had been regularly instituted and inducted before "the Great Rebellion". George Green, vicar of Theddingworth since 1620, embraced the Parliamentary cause and was unwilling to subscribe to the new conditions. Others presented during the Commonwealth had successfully concealed their episcopalian sympathies; some had even been ordained by one of the bishops active during the period. These willingly subscribed, sought eipiscopal ordination if needed, and retained their benefices unless an ejected predecessor appeared. The ejected ministers followed different courses. Some took part of their parishioners with them to form separatist congregations; some became school-teachers or doctors ; others retired to a patron's house and acted as his chaplain. In leaving the established church the ministers and their congregations were only following the example of the Baptists, Quakers and other gathered churches, but they did so most reluctantly. They still believed in one State church, but a church founded on Presbyterian or Congregational principles. Several attempts at reunion during the following years were welcomed by them.

description: Finding the solutions of the equations that describe the dynamics of a given physical system is crucial in order to obtain important information about its evolution. However, by using estimation theory, it is possible to obtain, under certain limitations, some information on its dynamics. The quantum-speed-limit (QSL) theory was originally used to estimate the shortest time in which a Hamiltonian drives an initial state to a final one for a given fidelity. Using the QSL theory in a slightly different way, we are able to estimate the running time of a given quantum process. For that purpose, we impose the saturation of the Anandan-Aharonov bound in a rotating frame of reference where the state of the system travels slower than in the original frame (laboratory frame). Through this procedure it is possible to estimate the actual evolution time in the laboratory frame of reference with good accuracy when compared to previous methods. Our method is tested successfully to predict the time spent in the evolution of nuclear spins 1/2 and 3/2 in NMR systems. We find that the estimated time according to our method is better than previous approaches by up to four orders of magnitude. One disadvantage of our method is that we need to solve a number of transcendental equations, which increases with the system dimension and parameter discretization used to solve such equations numerically.

description: Channel estimation is challenging for millimeter-wave (mmWave) massive MIMO with hybrid precoding, since the number of radio frequency (RF) chains is much smaller than that of antennas. Conventional compressive sensing based channel estimation schemes suffer from severe resolution loss due to the channel angle quantization. To improve the channel estimation accuracy, we propose an iterative reweight (IR)-based super-resolution channel estimation scheme in this paper. By optimizing an objective function through the gradient descent method, the proposed scheme can iteratively move the estimated angle of arrivals/departures (AoAs/AoDs) towards the optimal solutions, and finally realize the super-resolution channel estimation. In the optimization, a weight parameter is used to control the tradeoff between the sparsity and the data fitting error. In addition, a singular value decomposition (SVD)-based preconditioning is developed to reduce the computational complexity of the proposed scheme. Simulation results verify the better performance of the proposed scheme than conventional solutions.

description: We consider the problem of routing a data packet through the visibility graph of a polygonal domain $P$ with $n$ vertices and $h$ holes. We may preprocess $P$ to obtain a label and a routing table for each vertex of $P$. Then, we must be able to route a data packet between any two vertices $p$ and $q$ of $P$, where each step must use only the label of the target node $q$ and the routing table of the current node. For any fixed $\varepsilon > 0$, we present a routing scheme that always achieves a routing path whose length exceeds the shortest path by a factor of at most $1 + \varepsilon$. The labels have $O(\log n)$ bits, and the routing tables are of size $O((\varepsilon^{-1}+h)\log n)$. The preprocessing time is $O(n^2\log n)$. It can be improved to $O(n^2)$ for simple polygons.

description: It is well known that there is an absolute constant $\mathfrak{C}>0$ such that if the Laplace transform $G(s)=\int_{0}^{\infty}ρ(x)e^{-s x}\:\mathrm{d}x$ of a bounded function $ρ$ has analytic continuation through every point of the segment $(-iλ,iλ)$ of the imaginary axis, then $$ \limsup_{x\to\infty} \left|\int_{0}^{x}ρ(u)\:\mathrm{d}u - G(0)\right|\leq \frac{ \mathfrak{C}}λ \: \limsup_{x\to\infty} |ρ(x)|. $$ The best known value of the constant $\mathfrak{C}$ was so far $\mathfrak{C}=2$. In this article we show that the inequality holds with $\mathfrak{C}=π/2$ and that this value is best possible. We also sharpen Tauberian constants in finite forms of other related complex Tauberian theorems for Laplace transforms.

description: Key Messages • Diversification away from tobacco production has been framed as a priority for Malawi. • From 2004 to 2019, the share of Malawian crop farmers producing tobacco fell from 16% to 5%, and tobaccoʼs share of the total value of crop production also declined sharply. • In important respects, a transition away from tobacco has already occurred. • Over this period, farm-gate prices for tobacco have declined relative to the prices of maize or fertilizer, as has the share of the export price that is received by farmers. • Research is needed to understand why the farm-gate share of tobacco export prices has declined, and how the livelihoods of smallholder farm-households that exited tobacco production have been affected. • Additional research should also identify the investments needed to develop viable alternatives to tobacco, including improvements in non-tobacco value chains and on-farm technologies.

description: We prove convergence results for expanding curvature flows in the Euclidean and hyperbolic space. The flow speeds have the form $F^{-p}$, where $p>1$ and $F$ is a positive, strictly monotone and 1-homogeneous curvature function. In particular this class includes the mean curvature $F=H$. We prove that a certain initial pinching condition is preserved and the properly rescaled hypersurfaces converge smoothly to the unit sphere. We show that an example due to Andrews-McCoy-Zheng can be used to construct strictly convex initial hypersurfaces, for which the inverse mean curvature flow to the power $p>1$ loses convexity, justifying the necessity to impose a certain pinching condition on the initial hypersurface.
description: 18 pages. We included an example for the loss of convexity and pinching. In the third version we dropped the concavity assumption on F. Comments are welcome

description: We make the case for studying the complexity of approximately simulating (sampling) quantum systems for reasons beyond that of quantum computational supremacy, such as diagnosing phase transitions. We consider the sampling complexity as a function of time $t$ due to evolution generated by spatially local quadratic bosonic Hamiltonians. We obtain an upper bound on the scaling of $t$ with the number of bosons $n$ for which approximate sampling is classically efficient. We also obtain a lower bound on the scaling of $t$ with $n$ for which any instance of the boson sampling problem reduces to this problem and hence implies that the problem is hard, assuming the conjectures of Aaronson and Arkhipov [Proc. 43rd Annu. ACM Symp. Theory Comput. STOC '11]. This establishes a dynamical phase transition in sampling complexity. Further, we show that systems in the Anderson-localized phase are always easy to sample from at arbitrarily long times. We view these results in the light of classifying phases of physical systems based on parameters in the Hamiltonian. In doing so, we combine ideas from mathematical physics and computational complexity to gain insight into the behavior of condensed matter, atomic, molecular and optical systems.

description: Reinforcement learning (RL) has recently regained popularity, with major achievements such as beating the European game of Go champion. Here, for the first time, we show that RL can be used efficiently to train a spiking neural network (SNN) to perform object recognition in natural images without using an external classifier. We used a feedforward convolutional SNN and a temporal coding scheme where the most strongly activated neurons fire first, while less activated ones fire later, or not at all. In the highest layers, each neuron was assigned to an object category, and it was assumed that the stimulus category was the category of the first neuron to fire. If this assumption was correct, the neuron was rewarded, i.e. spike-timing-dependent plasticity (STDP) was applied, which reinforced the neuron's selectivity. Otherwise, anti-STDP was applied, which encouraged the neuron to learn something else. As demonstrated on various image datasets (Caltech, ETH-80, and NORB), this reward modulated STDP (R-STDP) approach extracted particularly discriminative visual features, whereas classic unsupervised STDP extracts any feature that consistently repeats. As a result, R-STDP outperformed STDP on these datasets. Furthermore, R-STDP is suitable for online learning, and can adapt to drastic changes such as label permutations. Finally, it is worth mentioning that both feature extraction and classification were done with spikes, using at most one spike per neuron. Thus the network is hardware friendly and energy efficient.

description: Zipf-like distributions characterize a wide set of phenomena in physics, biology, economics and social sciences. In human activities, Zipf-laws describe for example the frequency of words appearance in a text or the purchases types in shopping patterns. In the latter, the uneven distribution of transaction types is bound with the temporal sequences of purchases of individual choices. In this work, we define a framework using a text compression technique on the sequences of credit card purchases to detect ubiquitous patterns of collective behavior. Clustering the consumers by their similarity in purchases sequences, we detect five consumer groups. Remarkably, post checking, individuals in each group are also similar in their age, total expenditure, gender, and the diversity of their social and mobility networks extracted by their mobile phone records. By properly deconstructing transaction data with Zipf-like distributions, this method uncovers sets of significant sequences that reveal insights on collective human behavior.

description: We apply Heine's method---the key idea Heine used in 1846 to derive his famous transformation formula for $_2ϕ_1$ series---to multiple basic series over the root system of type $A$. In the classical case, this leads to a bibasic extension of Heine's formula, which was implicit in a paper of Andrews which he wrote in 1966. As special cases, we recover extensions of many of Ramanujan's $_2ϕ_1$ transformations. In addition, we extend previous work of the author regarding a bibasic extension of Andrews' $q$-Lauricella function, and show how to obtain very general transformation formulas of this type. The results obtained include transformations of an $n$-fold sum into an $m$-fold sum.

description: To-day the Reverend Humphrey Perkins is best remembered for the school which he founded in the village of his birth, Barrow-upon-Soar; yet his clerical career is important in several ways. It shows that a boy of middle-class parents could in the late seventeenth century make his way up the clerical ladder of preferment, but only so far. Humphrey Perkins never reached the top - he never enjoyed a well paid prebend or other Cathedral dignity. His career shows, too, the extreme importance of influence in ecclesiastical affairs at that time. Humphrey Perkins was fortunate in that he possessed several influential friends - otherwise, with his background, he would not have enjoyed such success in the clerical world as he did. He was a pluralist parson and, while the Anglican authorities realised that they could do little to stem the practice, they did take measures designed to curb its growth. Finally; his career is important in an attempt to form a judgment of the Church of England in the early eighteenth century.

description: We study covariant open bosonic string field theories on multiple $Dp$-branes by using the deformed cubic string field theory which is equivalent to the string field theory in the proper-time gauge. Constructing the Fock space representations of the three-string vertex and the four-string vertex on multiple $Dp$-branes, we obtain the field theoretical effective action in the zero-slope limit. On the multiple $D0$-branes, the effective action reduces to the Banks-Fishler-Shenker-Susskind (BFSS) matrix model. We also discuss the relation between the open string field theory on multiple $D$-instantons in the zero-slope limit and the Ishibashi-Kawai-Kitazawa-Tsuchiya (IKKT) matrix model. The covariant open string field theory on multiple $Dp$-branes would be useful to study the non-perturbative properties of quantum field theories in $(p+1)$-dimensions in the framework of the string theory. The non-zero-slope corrections may be evaluated systematically by using the covariant string field theory.

description: Following the emergence of many novel two-dimensional (2-D) materials beyond graphene, interest has grown in exploring implications for fundamental physics and practical applications, ranging from electronics, photonics, phononics, to thermal management and energy storage. In this Colloquium, we first summarize and compare the phonon properties, such as phonon dispersion and relaxation time, of pristine 2-D materials with single layer graphene to understand the role of crystal structure and dimension on thermal conductivity. We then compare the phonon properties, contrasting idealized 2-D crystals, realistic 2-D crystals, and 3-D crystals, and synthesizing this to develop a physical picture of how the sample size of 2-D materials affects their thermal conductivity. The effects of geometry, such as number of layers, and nanoribbon width, together with the presence of defects, mechanical strain, and substrate interactions, on the thermal properties of 2-D materials are discussed. Intercalation affects both the group velocities and phonon relaxation times of layered crystals and thus tunes the thermal conductivity along both the through-plane and basal-plane directions. We conclude with a discussion of the challenges in theoretical and experimental studies of thermal transport in 2-D materials. The rich and special phonon physics in 2-D materials make them promising candidates for exploring novel phenomena such as topological phonon effects and applications such as phononic quantum devices.

description: We address the problem of magnetic field dissipation in the neutron star cores, focusing on the role of neutron superfluidity. Contrary to the results in the literature, we show that in the finite-temperature superfluid matter composed of neutrons, protons, and electrons, magnetic field dissipates exclusively due to Ohmic losses and non-equilibrium beta-processes, and only an admixture of muons restores (to some extent) the role of particle relative motion for the field dissipation. The reason for this discrepancy is discussed.

description: One of the most important Leicestershire personalities in the Tudor period was Thomas Nevill of Nevill Holt. Leland said of him in 1564: 'Neville of Holte was among the Gentilmen of Leyrcestershir that be there most of reputation.' Nevill was a fairly common surname in sixteenth-century England and to distinguish this Thomas from several other Thomas Nevills who lived at this time contemporaries usually referred to him, as Leland did, as Nevill of the Holt. Nevill of the Holt owed some of his reputation to the fact that he spent a period at court where in the 1530s he was one of a group of courtiers who supported Thomas Cromwell

description: It is a common problem in lattice QCD calculation of the mass of the hadron with an annihilation channel that the signal falls off in time while the noise remains constant. In addition, the disconnected insertion calculation of the three-point function and the calculation of the neutron electric dipole moment with the $θ$ term suffer from a noise problem due to the $\sqrt{V}$ fluctuation. We identify these problems to have the same origin and the $\sqrt{V}$ problem can be overcome by utilizing the cluster decomposition principle. We demonstrate this by considering the calculations of the glueball mass, the strangeness content in the nucleon, and the CP violation angle in the nucleon due to the $θ$ term. It is found that for lattices with physical sizes of 4.5 - 5.5 fm, the statistical errors of these quantities can be reduced by a factor of 3 to 4. The systematic errors can be estimated from the Akaike information criterion. For the strangeness content, we find that the systematic error is of the same size as that of the statistical one when the cluster decomposition principle is utilized. This results in a 2 to 3 times reduction in the overall error.

Validation of semi-analytical approach for prediction of crack initiation in adhesive joints for wind turbine blades subjected to cyclic loading

description: Wind turbine rotor blades are subject to high dynamic loads and designed for life cycles of at least 20 years, which means that materials are subjected to high-cycle fatigue. Fatigue is a design-driving loading for current and future blades. Bond lines of blades are exposed to a multi-axial stress-state due to the anisotropic thin-walled blade structure and curved, tapered, twisted, and airfoil-shaped blade geometry. To eliminate undesirable failure modes and thus increase the reliability of wind turbine rotor blades, standards and guidelines recommend that the multi-axial stress-states be taken into consideration for the limit state analysis. In addition, thermal residual stresses that develop during manufacture can have a significant impact on the fatigue life of the bond line. To this end, we propose a sub-model system of analytical and semi-analytical approaches that take into account the multi-axial mean and amplitude stress-state in the trailing-edge adhesive joint. First, classical laminated plate theory (Reddy, 2004) represents the trailing-edge as a plate and takes into account longitudinal and transverse stresses within the adhesive layer plane. Second, Mittelstedt and Becker’s (2006) approach considers the free-edge effect that occurs at the outer trailing-edge adhesive joint. Third, a 2D finite element model of the adhesive joint subjected to a generalized plane strain, peel, and shear forces was considered as a reference. A finite element shell model was implemented which provided the loads for the sub-model system. The stress-life of the adhesive material was estimated on the basis of coupon tests of different stress ratios within the low cycle to high cycle fatigue regime. Probabilistic linear and non-linear stress-life models on this basis were used. By means of a cyclic full-scale blade test of a commercial 81.6 m long offshore blade, we validate the sub-model system of the trailing-edge adhesive joints, which takes into account multi-axial thermal and mechanical stress-states, to predict the crack initiation. On the one hand, qualitative criteria were considered such as the span-wise position and adhesive edge, and quantitative criteria such as cycle number to failure and equivalent stress level on the other. Both, qualitative and quantitative experimental observations agreed well with the simulations. All residual normal stress components and cross-sectional plane shear stress made up the major part of the mean equivalent stress while the mechanical stress amplitude components longitudinal, peel, and cross-sectional plane shear stress made up the major part of the equivalent stress amplitude.
