The long-term consequences of short-term responses to disturbance: Experiences from whalewatching impact assessment

open access: yes, 2007
Studies often use behavioral responses to detect the impact of given disturbances on animals. However, the observation of these short-term responses can often lead to contradicting results.

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Long-term evolution of initially unvirialized, clumpy, mass-segregated star clusters in tidal fields

open access: yes, 2017
Star clusters can form in highly substructured configurations, possibly unvirialized and possibly with a primordial degree of mass segregation. None the less, a common assumption of many N-body simulations of star clusters is that the clusters are ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

O-2 evolution and cyclic electron flow around photo system I in long-term ground batch culture of Euglena gracilis

open access: yes, 2014
Based on the purpose of better exploring the function of green producers in the closed aquatic biological life support system, the condition of dynamic 02 evolution and performance of cyclic electron flow around photosystem I (CEF-PSI) in long-term ...

Long-term evolution of multiple sclerosis disability in the treatment era

open access: yesAnnals of Neurology, 2016
To characterize the accrual of long‐term disability in a cohort of actively treated multiple sclerosis (MS) patients and to assess whether clinical and magnetic resonance imaging (MRI) data used in clinical trials have long‐term prognostic value.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Research and Development for Near Detector Systems Towards Long Term Evolution of Ultra-precise Long-baseline Neutrino Experiments [PDF]

open access: yes, 2019
With the discovery of non-zero value of $\theta_{13}$ mixing angle, the next generation of long-baseline neutrino (LBN) experiments offers the possibility of obtaining statistically significant samples of muon and electron neutrinos and anti-neutrinos ...
