• 2-chains: an interesting family of posets 

  Fayers, M (Elsevier, 2020-05-23)

  We introduce a new family of finite posets which we call 2-chains. These first arose in the study of 0-Hecke algebras, but they admit a variety of different characterisations. We give these characterisations, prove that ...

• Multicritical Scaling in a Lattice Model of Vesicles 

  Haug, N; Prellberg, T

  Vesicles, or closed fluctuating membranes, have been modeled in two dimensions by self-avoiding polygons, weighted with respect to their perimeter and enclosed area, with the simplest model given by area-weighted excursions. ...

  Yela, DF; Thalmann, F; Nicosia, V; Stowell, D; Sandler, M (American Physical Society, 2020-04)

  A visibility algorithm maps time series into complex networks following a simple criterion. The resulting visibility graph has recently proven to be a powerful tool for time series analysis. However its straightforward ...

• Explosive higher-order Kuramoto dynamics on simplicial complexes 

  Millán, AP; Torres, JJ; Bianconi, G (American Physical Society, 2020)

  The higher-order interactions of complex systems, such as the brain, are captured by their simplicial complex structure and have a significant effect on dynamics. However the existing dynamical models defined on simplicial ...

• Randomly weighted d-complexes: Minimal spanning acycles and Persistence diagrams 

  Skraba, P; Thoppe, G; Yogeshwaran, D (The Electronic Journal of Combinatorics, 2020-04-17)

  A weighted d -complex is a simplicial complex of dimension d in which each face is assigned a real-valued weight. We derive three key results here concerning persistence diagrams and minimal spanning acycles (MSAs) ...

  BACKGROUND: In the face of rapidly changing data, a range of case fatality ratio estimates for coronavirus disease 2019 (COVID-19) have been produced that differ substantially in magnitude. We aimed to provide robust ...

• Correlation for permutations 

  Johnson, J; Leader, I; Long, E (Elsevier, 2020-04)

  In this note we investigate correlation inequalities for `up-sets' of permutations, in the spirit of the Harris--Kleitman inequality. We focus on two well-studied partial orders on $S_n$, giving rise to differing notions ...

• A covariance formula for topological events of smooth Gaussian fields 

  Muirhead, S; Beliaev, D; Rivera, A (Institute of Mathematical Statistics, 2020)

  We derive a covariance formula for the class of `topological events' of smooth Gaussian fields on manifolds; these are events that depend only on the topology of the level sets of the field, for example (i) crossing events ...

• A second moment bound for critical points of planar Gaussian fields in shrinking height windows 

  Muirhead, S (Elsevier, 2020-05)

  We consider the number of critical points of a stationary planar Gaussian field, restricted to a large domain, whose heights lie in a certain interval. Asymptotics for the mean of this quantity are simple to establish via ...

• Anderson localisation in stationary ensembles of quasiperiodic operators 

  Chulaevsky, V; Sodin, A (Yokohama Publishers, 2020)

  An ensemble of quasi-periodic discrete Schro ̈dinger operators with an arbitrary number of basic frequencies is considered, in a lattice of arbitrary dimension, in which the hull function is a realisation of a stationary ...

• Nonextensive statistical mechanics, superstatistics and beyond: theory and applications in astrophysical and other complex systems 

  Beck, C; Benedek, G; Livadiotis, G; Rapisarda, A; Tirnakli, U; Tsallis, C (Springer, 2020-03)

  A brief illustration is presented about the scientific motivation and contributions of this Special Issue.

• GENERATING FUNCTIONS AND TOPOLOGICAL COMPLEXITY 

  Farber, M; Kishimoto, D; Stanley, D (Elsevier, 2020)

  We examine the rationality conjecture raised in [1] which states that (a) the formal power series 􏰀 a rational function of x with a single pole of order 2 at x = 1 and (b) the leading coefficient of the pole equals ...

• Using Scanning Electron Microscopy and Atomic Force Microscopy to Study the Formation of Nanoparticles on Red Blood Cell Surface in Cervical Cancer Patients 

  Mamaeva, S; Kononova, I; Ruzhansky, M; Nikiforov, P; Nikolaevа, N; Pavlov, A; Fedorova, N; Huang, J; Semenova, M; Barashkova, D (International Medical Research and Development Corporation, 2020-03-25)

  Background: In this study, we used scanning electron microscopy (SEM) and atomic force microscopy (AFM) to examine the changes in morphology of red blood cells (RBCs) and to investigate the nanoparticles (NPs) found on ...

• ON A NON-LOCAL PROBLEM FOR A MULTI-TERM FRACTIONAL DIFFUSION-WAVE EQUATION 

  Ruzhansky, M; Tokmagambetov, N; Torebek, BT (De Gruyter, 2020)

  This paper deals with the multi-term generalisation of the time-fractional diffusion-wave equation for general operators with discrete spectrum, as well as for positive hypoelliptic operators, with homogeneous multi-point ...

• Substitutes for the Non-existent Square Lattice Designs for 36 Varieties 

  Bailey, RA; Cameron, PJ; Soicher, LH; Williams, ER (Springer, 2020-01-01)

  Square lattice designs are often used in trials of new varieties of various agricultural crops. However, there are no square lattice designs for 36 varieties in blocks of size six for four or more replicates. Here, we use ...

• Simplicial complexes: higher-order spectral dimension and dynamics 

  Torres, JJ; Bianconi, G (IOP, 2020)

  Simplicial complexes constitute the underlying topology of interacting complex systems including among the others brain and social interaction networks. They are generalized network structures that allow to go beyond the ...

• On the standard $L$-function for $GSp_{2n} \times GL_1$ and algebraicity of symmetric fourth $L$-values for $GL_2$ 

  Pitale, A; Saha, A; Schmidt, R (Springer (part of Springer Nature), 2020)

  We prove an explicit integral representation -- involving the pullback of a suitable Siegel Eisenstein series -- for the twisted standard $L$-function associated to a holomorphic vector-valued Siegel cusp form of degree ...

• A Large Deviation Perspective on Ratio Observables in Reset Processes: Robustness of Rate Functions 

  Coghi, F; Harris, RJ (Springer Science and Business Media LLC, 2020-03)

  We study large deviations of a ratio observable in discrete-time reset processes. The ratio takes the form of a current divided by the number of reset steps and as such it is not extensive in time. A large deviation rate ...
