Preliminary geological interpretation of long-wavelength magnetic anomalies over China and surrounding regions

open access: yesEarth and Planetary Physics
Long-wavelength (>500 km) magnetic anomalies originating in the lithosphere were first found in satellite magnetic surveys. Compared to the striking magnetic anomalies around the world, the long-wavelength magnetic anomalies in China and surrounding ...

Reducing People?s Vulnerability to Natural Hazards: Communities and Resilience [PDF]

open access: yes
The concepts vulnerability, resilience and community are widely used and abused in the literature on natural hazards and disaster risk reduction. This paper seeks to bring greater rigour in their use.

Combining Ethological Thinking and Epidemiological Knowledge to Enhance the Naturalness of Organic Livestock Systems [PDF]

open access: yes, 2004
Organic livestock farming places strong emphasis on conditions that allow animals to exhibit behavioural needs. This involves the provision of a natural environment and, in particular, outdoor conditions and a reliance on natural forages.

CX3CL1 in Early Detection of Alzheimer's Disease: Plasma Dynamics Across Age and Disease Stages

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Backgrounds Alzheimer's disease (AD) is characterized by amyloid‐beta plaques, tau tangles, and neuroinflammation. C‐X3‐C motif chemokine ligand 1 (CX3CL1, also known as fractalkine), a neuroimmune chemokine implicated in AD pathogenesis, shows inconsistent alterations in plasma/serum across studies.

模拟地震波传播的谱元-有限差分混合方法

open access: yesDizhen xuebao
为了充分发挥谱元法和有限差分法各自在数值模拟复杂介质中地震波传播的优点,同时避免各自缺点,本文提出了模拟地震波传播的谱元-有限差分(SEM-FDM)混合方法。该混合方法在起伏地形附近采用谱元法计算地表附近的地震波传播;在远离起伏地形的区域之下,采用有限差分法计算地震波传播;之后通过构建数据交换区实现两种方法的耦合。结果表明,本文提出的谱元-有限差分混合方法能有效地模拟任意非均匀介质中的地震波传播,具有刻画复杂地形的能力,能处理自由地表边界条件,且能适应模型内的速度间断面。通过模型试算,并与谱元法进行对比,

Compound geohazards : planning for environmental change [PDF]

open access: yes, 2011
This research sets out to determine the potential effects of climate change on geohazards in the UK and focuses on one of the foremost natural hazards affecting the UK — flooding. In addition to the immediate effects of flooding, areas that are prone

Validity of a Wearable Digital Insole for Assessing Gait ON and OFF in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Gait impairment is a distinctive symptom of Parkinson's disease that negatively impact mobility. We assessed the validity of wearable digital insoles against a validated reference gait analysis system for measuring select gait characteristics in patients with Parkinson's disease. Methods A comparative analysis between digital insoles

24/7 population modelling for enhanced assessment of exposure to natural hazards

open access: yes, 2013
There is a growing need for accurate spatio-temporal population estimates free from arbitrary administrative boundaries and temporal divisions to make enhanced assessments of population exposure to natural hazards. The approach proposed here combines the
