On the multiway principal component analysis

open access: yesThe Annals of Statistics
Multiway data are becoming more and more common. While there are many approaches to extending principal component analysis (PCA) from usual data matrices to multiway arrays, their conceptual differences from the usual PCA, and the methodological implications of such differences remain largely unknown.

Why emerging leaders should focus on being good postdoctoral supervisors

open access: yesFEBS Letters, EarlyView.
Swamped with work and suddenly a new student is waiting at your doorstep for supervision? Great—this is your chance! In this article, we share tips on how postdocs can strengthen their leadership skills while supervising students. This image has been created using DALL·E. Many postdocs work as leaders later in their career.

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

MULTIPLE FACTOR ANALYSIS: MAIN FEATURES AND APPLICATION TO SENSORY DATA ANÁLISIS FACTORIAL MÚLTIPLE: PRINCIPALES CARACTERÍSTICAS Y SU APLICACIÓN A DATOS SENSORIALES

open access: yesRevista Colombiana de Estadística, 2004
Data table in which a single set of individuals is described by several groups of variables are frequently encountered. In the factor analysis framework, taking into account different groups of variables in a unique analysis firstly raises the problem of

Attempt to define morphological parameters enabling sex determination of Ips typographus (Linaeus, 1758) (Coleoptera: Curculionidae: Scolytinae) using PCA and CLU

open access: yesJournal of Forest Science, 2014
There are only two known methods for determining the sex of Ips typographus (L.) - dissection that can­not be used with live beetles and by distinguishing between the density of the hairs on the head, a less reliable method that requires experienced ...

Principal Component Projection Without Principal Component Analysis

open access: yes, 2016
We show how to efficiently project a vector onto the top principal components of a matrix, without explicitly computing these components. Specifically, we introduce an iterative algorithm that provably computes the projection using few calls to any black-box routine for ridge regression.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

The zinc finger domains of PARP‐1 are selectively and potently inhibited by the Au(I)‐based drugs sodium aurothiomalate and aurothioglucose

open access: yesFEBS Letters, EarlyView.
PARP‐1 is a key enzyme in the DNA damage response, and its inhibition induces cancer cell death via synthetic lethality. Au(I)‐based drugs, such as aurothioglucose and sodium aurothiomalate, block PARP‐1's DNA‐dependent activity by targeting its zinc finger domains.

Simultaneous Principal-Component Extraction with Application to Adaptive Blind Multiuser Detection

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
SIPEX-G is a fast-converging, robust, gradient-based PCA algorithm that has been recently proposed by the authors. Its superior performance in synthetic and real data compared with its benchmark counterparts makes it a viable alternative in applications
