Preliminary Spectral Analysis of SN 1994I [PDF]

open access: yes, 1995
We present optical spectra of the Type Ic supernova 1994I in M51 and preliminary non-LTE analysis of the spectra. Our models are not inconsistent with the explosions of C+O cores of massive stars.

Sleep Neurophysiological Dynamics Through the Lens of Multitaper Spectral Analysis.

open access: yesPhysiology, 2017
During sleep, cortical and subcortical structures within the brain engage in highly structured oscillatory dynamics that can be observed in the electroencephalogram (EEG).

Robust Spectral Analysis [PDF]

open access: yesSSRN Electronic Journal, 2011
In this paper I introduce quantile spectral densities that summarize the cyclical behavior of time series across their whole distribution by analyzing periodicities in quantile crossings. This approach can capture systematic changes in the impact of cycles on the distribution of a time series and allows robust spectral estimation and inference in ...

Visual Analysis of Carbendazim Residues in Carrot Tubers via Postionization Mass Spectrometry Imaging

open access: yesApplied Sciences
Carbendazim (CBZ) residues in food are a severe threat to food safety, and their detection is a challenging problem in food science. We introduce here a new method based on laser desorption postionization mass spectrometry imaging (LDPI-MSI) for ...

Leveraging current insights on IL‐10‐producing dendritic cells for developing effective immunotherapeutic approaches

open access: yesFEBS Letters, EarlyView.
In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/

Spectral analysis of lithium tremor

open access: yesArchives of Neuropsychiatry, 2020
Lithium has proven efficacy in bipolar affective disorder (BAD) but induces tremor as a side effect in a quarter of patients. Lithium tremor (LT) shares some clinical characteristics of essential tremor (ET) and Parkinson's disease tremor (PT), which might cause difficulties in differential diagnosis.

Localized Manifold Harmonics for Spectral Shape Analysis [PDF]

open access: yes, 2017
The use of Laplacian eigenfunctions is ubiquitous in a wide range of computer graphics and geometry processing applications. In particular, Laplacian eigenbases allow generalizing the classical Fourier analysis to manifolds.
