RTA‐408 Enhances Radiosensitivity and Inhibited Tumor Progression via JNK Pathway in Glioblastoma

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Glioblastoma (GBM) is an aggressive brain tumor with poor prognosis owing to its high invasiveness and resistance to therapy. RTA‐408, a synthetic triterpenoid and nuclear factor erythroid 2‐related factor 2 activator, exhibits anti‐inflammatory and anti‐cancer properties; however, its effects on GBM remain unclear. This study investigated the

The Kinematic and Microphysical Control of Storm Integrated Lightning Flash Extent [PDF]

open access: yes, 2012
Objective: To investigate the kinematic and microphysical control of lightning properties, particularly those that may govern the production of nitrogen oxides (NOx) in thunderstorms, such as flash rate, type (intracloud [IC] vs.

Critters in the Classroom: A 3D Computer-Game-Like Tool for Teaching Programming to Computer Animation Students [PDF]

open access: yes, 2007
The brewing crisis threatening computer science education is a well documented fact. To counter this and to increase enrolment and retention in computer science related degrees, it has been suggested to make programming "more fun" and to offer ...

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

open access: yesOikos, EarlyView.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.

Detection of VLF Attenuation in the Earth‐Ionosphere Waveguide Caused by X‐Class Solar Flares Using aGlobal Lightning Location Network

open access: yesSpace Weather, 2020
Solar flares, energetic particles, and Earth‐impacting coronal mass ejections enhance ionization in the lower ionosphere, inhibiting radio wave propagation in the Earth‐ionosphere waveguide (EIWG).

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

open access: yesPeople and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Environmental Impact of Silicic Magmatism in Large Igneous Province Events

open access: yesGeophysical Monograph Series, Page 133-151., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A 3-year observation on analyzing cloud-to-ground lightning in Peninsular Malaysia using graph theory

open access: yesAin Shams Engineering Journal
Malaysia has a high amount of lightning events due to its geographical location and tropical climate, leading to substantial destruction of electrical systems and human injuries.

The effect of the Earth's oblate spheroid shape on the accuracy of a time-of-arrival lightning ground strike locating system [PDF]

open access: yes
The algorithm used in previous technology time-of-arrival lightning mapping systems was based on the assumption that the earth is a perfect spheroid. These systems yield highly-accurate lightning locations, which is their major strength.

Detecting and attributing climate change effects on vegetation: Australia as a test case

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.
