Principal components of nuclear mass model residuals

Physics Letters B
Principal Component Analysis (PCA) is applied to the residuals of six widely used nuclear mass models to uncover systematic deviations and identify missing physical effects in theoretical nuclear mass predictions. By analyzing the principal components of

Dynamic Functional Principal Components [PDF]

Journal of the Royal Statistical Society Series B: Statistical Methodology, 2014
SummaryWe address the problem of dimension reduction for time series of functional data (Xt:t∈Z). Such functional time series frequently arise, for example, when a continuous time process is segmented into some smaller natural units, such as days. Then each X  t represents one intraday curve.

Prognosis of Long‐Term Continuous Renal Replacement Therapy and the Impact of Combined Continuous Intravenous Sodium Infusion Therapy

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.

Using artificial intelligence in analyzing principal components

Sustainable Engineering and Innovation
In this research, the basic concepts of both principal component analysis and artificial neural networks were reviewed, let alone tackling breast cancer, its most important causes and early detection. To add more, obtaining the principal components of a

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

A principal components approach to parent-to-newborn body composition associations in South India [PDF]

, 2009
Background: size at birth is influenced by environmental factors, like maternal nutrition and parity, and by genes. Birth weight is a composite measure, encompassing bone, fat and lean mass. These may have different determinants. The main purpose of this

Nonlocal foveated principal components [PDF]

2014 IEEE Workshop on Statistical Signal Processing (SSP), 2014
Patch foveation corresponds to a spatially variant representation where the center of the patch is sharp while the periphery is blurred. This mimics the non-uniformity of the human visual system, whose acuity is maximal at the fixation point (imaged by the fovea, i.e. the central part of the retina) and low at the periphery of the visual field.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Face processing: human perception and principal components analysis [PDF]

, 1996
Principal component analysis (PCA) of face images is here related to subjects' performance on the same images. In two experiments subjects were shown a set of faces and asked to rate them for distinctiveness.
