Development and validation of a method for linear-viscoelastic characterization of the dynamic complex modulus of short-fiber reinforced plastics using flexural resonances

open access: yesPolymer Testing, 2021
At present, the simulation cannot satisfactorily reproduce the actual vibration behavior of short-fiber reinforced plastics. This is because the required linear-viscoelastic material properties, in particular damping, are often not useable in the desired

The niche variation hypothesis predicts hunting returns across human cultures

open access: yesOikos, EarlyView.
The niche variation hypothesis (NVH) proposes that a broader population niche arises from greater individual specialization. Despite decades of empirical testing, research remains constrained to non‐human foragers, and the generality of NVH may extend beyond wildlife. The analysis of > 8000 hunting records from 12 human societies across four continents

Condition number analysis and preconditioning of the finite cell method [PDF]

open access: yes, 2016
The (Isogeometric) Finite Cell Method - in which a domain is immersed in a structured background mesh - suffers from conditioning problems when cells with small volume fractions occur.

Task co‐use and product improvement: An organization design perspective

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Co‐using tasks—using the same task to produce more than one product—promises economies of scope. However, task co‐use also ties products together, changing a firm's task network by introducing cross‐product interdependencies. In light of these interdependencies, we identify an unrecognized downside of task co‐use for product ...

Experimental and Comparative Study of Rotor Vibrations of Permanent Magnet Machines with Two Different Fractional Pole/Slot Combinations

open access: yesApplied Sciences, 2020
This study deals with the noise, vibration, and harshness (NVH) characteristic analysis of permanent magnet synchronous motors (PMSMs) for electrical machines, such as electrically driven tools that are used in industries.

Relationships Among Trophic Niche Width, Morphological Variation, and Genetic Diversity of Hemiculter leucisculus in China

open access: yesFrontiers in Ecology and Evolution, 2021
According to the niche variation hypothesis (NVH), the populations with wider niches are phenotypically more variable than those with narrow niches. Giller expanded the NVH, suggesting that the niche width, morphological variation, and genetic diversity ...

The Development of Indo‐Iranian Voiced Fricatives

open access: yesTransactions of the Philological Society, Volume 123, Issue 1, Page 97-115, March 2025.
Abstract The development of voiced sibilants is a long‐standing puzzle in Indo‐Iranian historical phonology. In Vedic, all voiced sibilants are lost from the system, but the details of this loss are complex and subject to debate. The most intriguing development concerns the word‐final ‐aḥ to ‐o in sandhi.

Emetic toxin-producing strains of Bacillus cereus show distinct characteristics within the Bacillus cereus group. [PDF]

open access: yes, 2006
One hundred representative strains of Bacillus cereus were selected from a total collection of 372 B. cereus strains using two typing methods (RAPD and FT-IR) to investigate if emetic toxin-producing hazardous B.

From Loss to Transformation? Towards Pluralistic and Politicised Agrarian‐Climate Futures

open access: yesAsia Pacific Viewpoint, EarlyView.
ABSTRACT Understanding how actors perceive and anticipate future states of the world is gaining traction in climate change governance scholarship and related calls for sustainability transformations. However, smallholder farmers, indigenous groups, and local communities, who are expected to bear disproportionate burdens of loss and damage from climate ...
