A Developed LSTM-Ladder-Network-Based Model for Sleep Stage Classification

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
Sleep staging is crucial for diagnosing sleep-related disorders. The heavy and time-consuming task of manual staging can be released by automatic techniques.

On the exact asymptotic behaviour of the distribution of ladder epochs

open access: yesStochastic Processes and Their Applications, 1982
AbstractLet T+ denote the first increasing ladder epoch in a random walk with a typical step-length X. It is known that for a large class of random walks with E(X)=0,E(X2)=∞, and the right-hand tail of the distribution function of X asymptotically larger than the left-hand tail, PT+⩾n∽n1β−1L+(n) as n→∞, with ...

BAO signatures in the 2-point angular correlations and the Hubble tension

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
An observational tension on estimates of the Hubble parameter, $$H_0$$ H 0 , using early and late Universe information, is being of intense discussion in the literature.

Ladder epochs and ladder chain of a Markov random walk with discrete driving chain [PDF]

open access: yesAdvances in Applied Probability, 2018
Abstract Let (Mn,Sn)n≥0 be a Markov random walk with positive recurrent driving chain (Mn)n≥0 on the countable state space 𝒮 with stationary distribution π. Suppose also that lim supn→∞Sn=∞ almost surely, so that the walk has almost-sure finite strictly ascending ladder epochs σn>. Recurrence properties of the ladder chain (Mσn>)n≥0 and a closely

Local limit theorems for ladder epochs

open access: yes, 2007
Let {S_n, n=0,1,2,...} be a random walk generated by a sequence of i.i.d. random variables X_1, X_2,... and let tau be the first descending ladder epoch. Assuming that the distribution of X_1 belongs to the domain of attraction of an alpha-stable law, we study the asymptotic behavior of P(tau=n).

Transhumanist Elements in ‘Understand’

open access: yesCurrent Perspectives in Social Sciences
Humans are progressing machines. Naturally, it is continuously changing and modifying not only itself but also everything around it, from a simple gadget to abstract concepts or questions asked from the very beginning of conscious ancestors’ times ...

Advancing Efficient Error Reduction in DNA Data Storage Systems with Deep Learning‐Based Denoising Models

open access: yesAdvanced Intelligent Discovery, EarlyView.
Deep learning‐based denoising models are applied to DNA data storage systems to enhance error reduction and data fidelity. By integrating DnCNN with DNA sequence encoding methods, the study demonstrates significant improvements in image quality and correction of substitution errors, revealing a promising path toward robust and efficient DNA‐based ...

Ladder top-quark condensation imprints in supercooled electroweak phase transition

open access: yesJournal of High Energy Physics
The electroweak (EW) phase transition in the early Universe might be supercooled due to the presence of the classical scale invariance involving Beyond the Standard Model (BSM) sectors and the supercooling could persist down till a later epoch around ...
