Nouvelles données sur les caractéristiques morphologiques immatures du crâne chez les Homo erectus asiatiques

open access: yesBulletins et Mémoires de la Société d’Anthropologie de Paris, 2007
It is critical to be able to recognize the juvenile specimens within the fossil record in order to determine the adult variability of the different taxa and to approach their ontogenetic and phylogenetic characteristics.

Impact of the Process Atmosphere During Hot Isostatic Pressing on the Near‐Surface Composition of an Additively Manufactured Austenitic High‐Interstitial Steel

open access: yesAdvanced Engineering Materials, EarlyView.
A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.

Testing the adaptive value of gastropod shell morphology to flow: a multidisciplinary approach based on morphometrics, computational fluid dynamics and a flow tank experiment

open access: yesZoological Letters, 2019
A major question in stream ecology is how invertebrates cope with flow. In aquatic gastropods, typically, larger and more globular shells with larger apertures are found in lotic (flowing water) versus lentic (stagnant water) habitats.

Boron-based refiners: Advantages in semi-solid-metal casting of Al-Si alloys

open access: yes, 2007
Inoculation has been studied in the semi-solid-metal (SSM) casting by sole boron addition. By boron addition, the structure is not only refined but also the sphericity of the primary α-Al particles increased.

Gyroid Structured Globugraphite Carbon Foam With Hierarchical and Tailored Pore Size

open access: yesAdvanced Engineering Materials, EarlyView.
Secondary sacrificial templates were designed and printed to create a defined network within a porous carbon. Lattices thermally degrades during the sintering process. Lattices are imprinted into the ceramic template and transferred to the morphology of Globugraphite.

Simple sequence proteins in prokaryotic proteomes

open access: yesBMC Genomics, 2006
Background The structural and functional features associated with Simple Sequence Proteins (SSPs) are non-globularity, disease states, signaling and post-translational modification.

Optimizing NiMo Electrocatalyst Coatings for Hydrogen Evolution in Alkaline Electrolysis With The Machine Learning‐Guided Autonomous Platform CatBot

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a closed‐loop optimization workflow integrating CatBot, an automated synthesis and testing system, to discover NiMo hydrogen‐evolution catalysts. CatBot synthesised and evaluated 228 unique samples, identifying the best performing catalysts for transfer to nickel‐foam electrodes. The best candidate is highly active, reaching 1 Acm−2${

Protein-based signatures of functional evolution in Plasmodium falciparum

open access: yesBMC Evolutionary Biology, 2011
Background It has been known for over a decade that Plasmodium falciparum proteins are enriched in non-globular domains of unknown function. The potential for these regions of protein sequence to undergo high levels of genetic drift provides a ...

Association-induced Folding of Globular Proteins

open access: yes, 1998
It has generally been assumed that the aggregation of partially folded intermediates during protein refolding results in the termination of further protein folding.
