The Whitehead group of the Novikov ring

open access: yes, 2000
The Bass-Heller-Swan-Farrell-Hsiang-Siebenmann decomposition of the Whitehead group $K_1(A_{\rho}[z,z^{-1}])$ of a twisted Laurent polynomial extension $A_{\rho}[z,z^{-1}]$ of a ring $A$ is generalized to a decomposition of the Whitehead group $K_1(A_ ...

Comparing Self‐Reported and Physician‐Assessed Acne Severity Using Real‐World Data

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Background Real‐world data (RWD) offers access to vast amounts of health information; however, limited knowledge exists regarding its reliability in clinical and research practices. Objectives To analyse the agreement between self‐assessed severity of self‐reported acne vulgaris (AV), and physician‐assessed severity based on photographic ...

From Whitehead’s conception of Mass and Spacetime towards the Universe as a Giant Carnot Engine

open access: yesФилософия и космология
Whitehead’s conception of space and time discloses a substantivalistic 4D-spacetime of observable events. His mass concept makes room for Verlinde’s approach of gravity as elastic response of mass created out of the de Sitter Space.

Parent-of-Origin DNA Methylation Dynamics during Mouse Development

open access: yesCell Reports, 2016
Parent-specific differentially methylated regions (DMRs) are established during gametogenesis and regulate parent-specific expression of imprinted genes. Monoallelic expression of imprinted genes is essential for development, suggesting that imprints are

Whitehead moves for G-trees

open access: yes, 2008
We generalize the familiar notion of a Whitehead move from Culler and Vogtmann's Outer space to the setting of deformation spaces of G-trees. Specifically, we show that there are two moves, each of which transforms a reduced G-tree into another reduced G-

Immunotherapy‐Related Cutaneous Toxicities in Melanoma: A Dermoscopic Perspective

open access: yesJEADV Clinical Practice, EarlyView.
Dermoscopy serves as a valuable tool in the everyday dermatological and oncological practice for melanoma patients, allowing for the prompt identification of immune‐related cutaneous toxicities and guiding clinicians toward appropriate therapeutic decisions.

open access: yesJournal of French and Francophone Philosophy, 2015
It is by now generally understood that the nature of events are central to Deleuze’s philosophical endeavour. This has not meant, however, that the process mapped out by this concept has been adequately grasped.

Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

Age of the Rotoehu Ash. Comment. [PDF]

open access: yes, 1995
Suggests that the article by Whitehead & Ditchburn (1994), although presenting useful new data on 230Th/232Th analyses, is flawed and misleading in suggesting that the Rotoiti Tephra is considerably younger than c.

Coccolithophore particulate inorganic and organic carbon ratios: An evaluation of acid decalcification methods

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate direct measurements of coccolithophore particulate inorganic and organic carbon ratios (PIC/POC) are crucial for understanding the physiology and role these microbes play in global ocean carbon flux. Direct measurements of POC are commonly obtained by acid fuming or applying acid directly to filters to dissolve PIC (CaCO3) prior to CN
