The development of a dynamic amplification estimator for bridges with good road profiles

open access: yes, 2006
The paper considers the influence of the surface profile on the dynamic amplification of a simply supported bridge when subject to a quarter car vehicle model.

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 ...

Development of Aircraft Flight Loads Analysis Models with Uncertainties for Pre-Design Studies

open access: yes, 2005
This paper addresses the development of analysis tools for flight loads prediction in the pre-design stage. The analysis tools are embedded in a parametric modelling environment.

Assessment of the Dynamic Loads Effect on Underground Mines Supports [PDF]

open access: yes, 2011
Blasting operations generate seismic effects in underground mines. These effects apply additional dynamic loads on the support system, which should bear both static and dynamic loads.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Safe dynamic design of structures. [PDF]

open access: yes, 2000
The Design of structures under dynamic loading is a demanding subject in safety of engineering design since conventional static failure criteria are unable to deal with structures under transient loading.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Dynamic characteristics of steel-deck composite floors under human induced loads

open access: yes, 2009
Steel-deck composite floor systems are a popular choice in high-rise buildings as they are economical and easy to construct. These composite floor systems use high strength materials to achieve longer spans, but are slender and vulnerable to vibration ...

Dynamic mechanical loads on PV-modules

open access: yes, 2022
S.3395 - 3397Photovoltaic (PV)-modules are not only exposed to static mechanical loads, such as snow and wind loads (for building integrated modules), as tested in the current standard IEC 61215.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

open access: yesMolecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.
