Epoxy resin‐based sealers modified with clay nanoparticles: Evaluation of their physicochemical and mechanical properties

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract Epoxy resin‐based sealers are commonly used in endodontic treatment due to their superior physicochemical properties. Therefore, it is important to utilize these materials by enhancing their properties. Nonetheless, several of their properties remain suboptimal, including the relatively prolonged setting time, the moderate yet clinically ...

Approximate Capacities of Two-Dimensional Codes by Spatial Mixing

open access: yes, 2014
We apply several state-of-the-art techniques developed in recent advances of counting algorithms and statistical physics to study the spatial mixing property of the two-dimensional codes arising from local hard (independent set) constraints, including ...

Throughput Optimization in High Speed Downlink Packet Access (HSDPA) [PDF]

open access: yes, 2009
In this paper, we investigate throughput optimization in High Speed Downlink Packet Access (HSDPA). Specifically, we propose offline and online algorithms for adjusting the Channel Quality Indicator (CQI) used by the network to schedule data ...

Structural investigation of human U6 snRNA recognition by spliceosomal recycling factor SART3 RNA recognition motifs

open access: yesThe FEBS Journal, EarlyView.
Human SART3 has two RRM domains to engage with U6 snRNA for spliceosome recycling. This study reports solution structures of SART3 RRM domains and investigates the interaction between RRM and U6 snRNA. SART3 binds to the asymmetric bulge of U6 snRNA as a dimer via conserved positively charged surfaces.

The potato cyst nematode Globodera pallida overcomes major potato resistance through selection on standing variation at a single locus

open access: yesNew Phytologist, EarlyView.
Summary Globodera pallida poses a major threat to potato production, with management strategies primarily relying on genetic resistance. However, increasing virulence in field populations across Western Europe raises major concerns for G. pallida control.

Structure mirroring function: What's the ‘matter’ with the funny current?

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The ‘funny’ (If) current of cardiac pacemaker cells has been first identified in the late 1970s as a major mechanism in the generation and control of cardiac pacemaking. Decades of studies have since described the properties of the funny current and of its molecular components, HCN channels, in the heart and brain, providing the ...

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.
