Enhancing Flow Separation Control Using Hybrid Passive and Active Actuators in a Matrix Configuration

open access: yesAerospace
Efficient control of flow separation holds significant economic promise. This study investigates flow separation mitigation using an experimental platform featuring a combination of passive and active actuators arranged in a matrix configuration.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Passivity-based output-feedback control of turbulent channel flow [PDF]

open access: yesAutomatica, 2016
This paper describes a robust linear time-invariant output-feedback control strategy to reduce turbulent fluctuations, and therefore skin-friction drag, in wall-bounded turbulent fluid flows, that nonetheless gives performance guarantees in the nonlinear turbulent regime.

474: lighting and thermal performance of innovative shading devices: new insights into their aesthetics and control in a Mediterranean climate [PDF]

open access: yes, 2008
With a view towards minimising energy demand for cooling and artificial lighting in buildings, this paper evaluates innovative shading devices and how they can balance a generous degree of control mastering seasonal natural light with thermal gains in a ...

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 ...

Review of Passive Flow Control Methods for Compressor Linear Cascades

open access: yesApplied Sciences
This paper reviews the evolution of flow control methods for bladed linear cascades, focusing on passive techniques like riblets, grooves, vortex generators (VGs), and blade slots, which have proven effective in reducing drag, suppressing flow separation,

Comparative efficacy of passive and mechanical fan-pad cooling system for microclimate modification and welfare in broiler production

open access: yesIndian Journal of Animal Sciences, 2016
Efficacy of passive cooling vis-à-vis mechanical fan-pad cooling system was assessed for microclimate modification to alleviate heat stress and improving growth performance and welfare of broilers. Cooling treatments comprised of Tc (control without any

Passive Control of Viscous Flow via Elastic Snap-Through [PDF]

open access: yesPhysical Review Letters, 2017
We demonstrate the passive control of viscous flow in a channel by using an elastic arch embedded in the flow. Depending on the fluid flux, the arch may `snap' between two states --- constricting and unconstricting --- that differ in hydraulic conductivity by up to an order of magnitude.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in
