generalisation of the SRVT from Euclidean spaces to shape spaces of curves on
Lie groups and on homogeneous manifolds. The main idea behind our approach is
to exploit the geome... | 0 | 0 | 1 | 0 | 0 | 0 |
Markov Models for Health Economic Evaluations: The R Package heemod | Health economic evaluation studies are widely used in public health to assess

guidelines: determ... | 0 | 0 | 0 | 1 | 0 | 0 |
Amorphous Alloys, Degradation Performance of Azo Dyes: Review | Today freshwater is more important than ever before and it is contaminated

Towards the ab initio based theory of the phase transformations in iron and steel | Despite of the appearance of numerous new materials, the iron based alloys
and steels continue to play an essential role in modern technology. The
properties of a steel are determined by its structural state (ferrite,
cementite, pearlite, bainite, martensite, and their combination) that is formed

Solitons in a modified discrete nonlinear Schroedinger equation | We study the bulk and surface nonlinear modes of the modified one-dimensional
discrete nonlinear Schroedinger (mDNLS) equation. A linear and a modulational
stability analysis of the lowest-order modes is carried out. While for the
fundamental bulk mode there is no power threshold, the fundamental surface mode

Functional renormalization-group approach to the Pokrovsky-Talapov model via modified massive Thirring fermion model | A possibility of the topological Kosterlitz-Thouless~(KT) transition in the
Pokrovsky-Talapov~(PT) model is investigated by using the functional

Reentrant Phase Coherence in Superconducting Nanowire Composites | The short coherence lengths characteristic of low-dimensional superconductors

temperature $T$, m... | 0 | 1 | 0 | 0 | 0 | 0 |
Micromagnetic Simulations for Coercivity Improvement through Nano-Structuring of Rare-Earth Free L1$_0$-FeNi Magnets | In this work we investigate the potential of tetragonal L1$_0$ ordered FeNi

In particular, we estimate the maximum energy product ($BH$)$_\mathrm{max}$ of

Semi-parametric Dynamic Asymmetric Laplace Models for Tail Risk Forecasting, Incorporating Realized Measures | The joint Value at Risk (VaR) and expected shortfall (ES) quantile regression
model of Taylor (2017) is extended via incorporating a realized measure, to

returns. Both a maximum likelihood and an adaptive Bayesian Markov Chain Monte

Mobility tensor of a sphere moving on a super-hydrophobic wall: application to particle separation | The paper addresses the hydrodynamic behavior of a sphere close to a

Influence of Resampling on Accuracy of Imbalanced Classification | In many real-world binary classification tasks (e.g. detection of certain
objects from images), an available dataset is imbalanced, i.e., it has much
less representatives of a one class (a minor class), than of another.
Generally, accurate prediction of the minor class is crucial but it's hard to
achieve since there ... | 1 | 0 | 0 | 1 | 0 | 0 |
Literature Survey on Interplay of Topics, Information Diffusion and Connections on Social Networks | Researchers have attempted to model information diffusion and topic trends

Extended B-Spline Collocation Method For KdV-Burgers Equation | The extended form of the classical polynomial cubic B-spline function is used

derivatives of the cubic B-splines forces us to reduce the order of the term

On smile properties of volatility derivatives and exotic products: understanding the VIX skew | We develop a method to study the implied volatility for exotic options and

Risk-Sensitive Optimal Control of Queues | We consider the problem of designing risk-sensitive optimal control policies

SPECULOOS exoplanet search and its prototype on TRAPPIST | One of the most significant goals of modern science is establishing whether

Small-dimensional representations of algebraic groups of type $A_l$ | For $G$ an algebraic group of type $A_l$ over an algebraically closed field
of characteristic $p$, we determine all irreducible rational representations of

Looping and Clustering model for the organization of protein-DNA complexes on the bacterial genome | The bacterial genome is organized in a structure called the nucleoid by a
