Pump‐Probe Imaging of Ultrafast Laser Percussion Drilling of Glass in Single Pulse, MHz‐ and GHz‐Burst Regimes

open access: yesAdvanced Materials Interfaces, EarlyView.
Pump‐probe shadowgraphy of glass drilling is shown with a femtosecond laser operating in MHz‐ and GHz‐burst regime. A comparison with standard femtosecond micro‐processing using repetitive single pulses is provided. The ablation plume lifetime is measured in all three regimes, and the drilling dynamics of Through Glass Via (TGV) in GHz‐burst mode are ...

A Bilayer Micro/Nanostructured Water‐Based Paint With Effective Thermal Insulating and Reflective Properties

open access: yesAdvanced Materials Interfaces, EarlyView.
The design, optimization and characterization of a new bilayer painting system is presented. The underlying layer is engineered to provide exceptional thermal insulation through the synergistic effect of hollow perlite microspheres and micrometer‐sized cellulose particles. The external painting layer is designed to induce the formation of a homogeneous

Molecular recognition in olfaction

open access: yesAdvances in Physics: X, 2017
The mechanism by which the chemical identity of odourants is established by olfactory receptors is a matter of intense debate. Here we present an overview of recent ideas and data with a view to summarising what is known, and what has yet to be ...

Genetic algorithm eclipse mapping [PDF]

open access: yesarXiv, 2008
In this paper we analyse capabilities of eclipse mapping technique, based on genetic algorithm optimization. To model of accretion disk we used the "fire-flies" conception. This model allows us to reconstruct the distribution of radiating medium in the disk using less number of free parameters than in other methods. Test models show that we can achieve

Defect Generation and Evolution in Irradiated Epitaxial Films and Heterostructures of Fe3O4 and Cr2O3

open access: yesAdvanced Materials Interfaces, EarlyView.
The functionality of nuclear structural materials, sensors, and microelectronics in radiation environments relies on understanding defect generation and evolution processes in oxide layers. The initial radiation response of Fe3O4 epitaxial thin films is characterized by the formation of large vacancy clusters, but these defects do not lead to lattice ...

Continuous Circadian Phase Estimation Using Adaptive Notch Filter [PDF]

open access: yesarXiv, 2018
Actigraphy has been widely used for the analysis of circadian rhythm. Current practice applies regression analysis to data from multiple days to estimate the circadian phase. This paper presents a filtering method for online processing of biometric data to estimate the circadian phase.

Preferential Membrane Remodeling on Curved Biointerfaces Induced by Conjugated Oligoelectrolyte

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores how membrane shape influences the interaction of conjugated oligoelectrolytes (COEs) with lipid bilayers. Using a curved biointerface composed of nanobar arrays and supported lipid bilayers, it is revealed that COE intercalation preferentially remodels curved regions, forming distinct structures. These findings highlight the role of

Flies: The Important Role in Medicine

open access: yesJournal of Health Science and Medical Research (JHSMR), 2012
Filth flies are major insect vectors responsible for the spread of human food-borne disease, especially those causing diarrheal illness. In Thailand, the three most common families of synanthropic flies are Muscidae (house flies), Sarcophagidae (flesh ...
