Presentism and the Micro-Structure of Time

open access: yesPhilosophy Kitchen, 2020
The standard account of the micro-structure of time is based on Cantor’s conception of continuity and thus views the time line as consisting of undenumerably many instants ordered by the B-theoretic earlier than relation. This may seem problematic for an A-theory of time such as presentism, according to which only what is present exists, for it seems ...

Study of Evaporation Phenomena in Micro Channels [PDF]

open access: yes, 2010
Two-phase convective flow in micro channels has numerous promising applications such as electronic cooling. This study investigates evaporation phenomena and capillary-driven heat in a rectangular micro channels structure with hydraulic diameters of 100 ~

Preparation and Properties Study of Cr on FeCrAl Cladding Materials

open access: yesFrontiers in Materials, 2021
FeCrAl alloy is a promising candidate material for the fourth-generation reactor core cladding material. Adjustment of the Cr content is one of the effective ways to obtain enhanced performance for the FeCrAl alloy. In this work, Fe–xCr–6Al alloy (11 ≤ x

Micro-crystalline structure of platinum [PDF]

open access: yesProceedings of the Royal Society of London, 1902
Abstract The crystalline structure of platinum does not appear to have been studied, although it forms an interesting subject for investigation. A small ingot of pure platinum was obtained for the experiments. A section was cut therefrom and machined to 5/16 inch square and 1/10 inch in thickness.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Capital structure decision: micro- and macroeconomic determinants in Malaysia [PDF]

open access: yes, 2020
This paper attempts to analyse the determinants of capital structure decisions among Malaysian firms by considering both the firm-specific (micro-economic) and the macro-economic factors.

Design and Experimental Performance of a Novel Piezoelectric Inertial Actuator for Magnetorheological Fluid Control Using Permanent Magnet

open access: yesIEEE Access, 2019
A piezoelectric inertial actuator for magnetorheological fluid (MRF) control using permanent magnet is proposed in this paper. The stable linear motion of the actuator with high controllability is obtained by integrating the piezoelectric vibrator and ...

The role of mechanobiology on the Schwann cell response: A tissue engineering perspective

open access: yesFrontiers in Cellular Neuroscience, 2022
Schwann cells (SCs), the glial cells of the peripheral nervous system (PNS), do not only form myelin sheaths thereby insulating the electrical signal propagated by the axons, but also play an essential role in the regeneration of injured axons.

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 ...
