Isoparametric hypersurfaces and complex structures [PDF]
, 2022 The main purpose of this note is to construct almost complex or complex structures on certain isoparametric hypersurfaces in unit spheres. As a consequence, complex structures on $S^1\times S^7\times S^6$, and on $S^1\times S^3\times S^2$ with vanishing first Chern class, are built.

Fractional-Order Discrete-Time SIR Epidemic Model with Vaccination: Chaos and Complexity
Mathematics, 2022 This research presents a new fractional-order discrete-time susceptible-infected-recovered (SIR) epidemic model with vaccination. The dynamical behavior of the suggested model is examined analytically and numerically.

BMC Public Health, 2017 Background As service provision and patient behaviour varies by day, healthcare data used for public health surveillance can exhibit large day of the week effects. These regular effects are further complicated by the impact of public holidays.

Accurate Estimate of the Advantage of Impossible Differential Attacks
IACR Transactions on Symmetric Cryptology, 2017 Impossible differential attacks, which are taking advantage of differentials that cannot occur, are powerful attacks for block cipher primitives. The power of such attacks is often measured in terms of the advantage — number of key-bits found during the ...

Towards a Unified Framework of Matrix Derivatives
IEEE Access, 2018 The need of processing and analyzing massive statistics simultaneously requires the derivatives of matrix-to-scalar functions (scalar-valued functions of matrices) or matrix-to-matrix functions (matrixvalued functions of matrices).

Quantum chaos and the complexity of spread of states [PDF]
Physical Review D, 2022 We propose a measure of quantum state complexity defined by minimizing the spread of the wave-function over all choices of basis. Our measure is controlled by the"survival amplitude"for a state to remain unchanged, and can be efficiently computed in ...

Verifying Time Complexity of Deterministic Turing Machines [PDF]
, 2014 We show that, for all reasonable functions $T(n)=o(n\log n)$, we can algorithmically verify whether a given one-tape Turing machine runs in time at most $T(n)$. This is a tight bound on the order of growth for the function $T$ because we prove that, for $

Informer: Beyond Efficient Transformer for Long Sequence Time-Series Forecasting [PDF]
AAAI Conference on Artificial Intelligence, 2020 Many real-world applications require the prediction of long sequence time-series, such as electricity consumption planning. Long sequence time-series forecasting (LSTF) demands a high prediction capacity of the model, which is the ability to capture ...
