The mutational constraint spectrum quantified from variation in 141,456 humans

open access: yesNature, 2020
Genetic variants that inactivate protein-coding genes are a powerful source of information about the phenotypic consequences of gene disruption: genes that are crucial for the function of an organism will be depleted of such variants in natural ...

The empirical mode decomposition and the Hilbert spectrum for nonlinear and non-stationary time series analysis

open access: yesProceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1998
A new method for analysing nonlinear and non-stationary data has been developed. The key part of the method is the ‘empirical mode decomposition’ method with which any complicated data set can be decomposed into a finite and often small number of ...

Raman spectrum of graphene and graphene layers.

open access: yesPhysical Review Letters, 2006
Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality. We show that its electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers. The D peak second order changes in

Spectrum matching in licensed spectrum sharing [PDF]

open access: yesTransactions on Emerging Telecommunications Technologies, 2018
AbstractSpectrum sharing is one of the promising solutions to meet the spectrum demand in fifth‐generation networks that results from the emerging services like machine‐to‐machine and vehicle‐to‐infrastructure communication. The idea is to allow a set of entities to access the spectrum whenever and wherever it is unused by the licensed users.

A mobilization poster stimulates early in-hospital rehabilitation after cardiac surgery: a prospective sequential-group study

open access: yesJournal of Cardiothoracic Surgery, 2023
Background Patients infrequently mobilize at the surgical ward after cardiac surgery. Inactivity results in prolonged hospital stay, readmissions and increased cardiovascular mortality. Next, the course of in-hospital mobilization activities for patients

The Spectrum of the Universe [PDF]

open access: yesApplied Spectroscopy, 2018
Cosmic background (CB) radiation, encompassing the sum of emission from all sources outside our own Milky Way galaxy across the entire electromagnetic spectrum, is a fundamental phenomenon in observational cosmology. Many experiments have been conceived to measure it (or its constituents) since the extragalactic Universe was first discovered; in ...

Local spectrum and generalized spectrum [PDF]

open access: yesProceedings of the American Mathematical Society, 1991
This paper provides the proofs of those results announced in [ 5 , § 5 ] [5,\S 5] that deal with the connection between the regular set and the local resolvant set of closed operators on a Hilbert space. We also give some characterizations and properties of Cowen-Douglas operators.

Singular Spectrum Analysis: Methodology and Comparison

open access: yesJournal of Data Science, 2021
In recent years Singular Spectrum Analysis (SSA), used as a powerful technique in time series analysis, has been developed and applied to many practical problems. In this paper, the performance of the SSA tech- nique has been considered by applying it to
