Resource depletion aspects are repeatedly used as an argument for a shift towards new battery technologies. However, whether serious shortages due to the increased demand for traction and stationary batteries can actually be expected is subject to an ongoing discussion. In order to identify the principal drivers of resource depletion for battery production, we assess different lithium-ion batte...

Submitted: July 20, 2007; Revised: September 2, 2007; Accepted: September 5, 2007 Background: Cognitive deficits are fundamental features in schizophrenia (SZ) and major determinants of psychosocial functioning. Cognitive deficits in bipolar disorder (BD) were only recently recognized, and research on them is limited, especially in the euthymic stage. Earlier attempts to establish and compare t...

Executive functioning is a multidimensional concept encompassing higher-order adaptive abilities, such as judgment, decision-making, self-monitoring, planning, and emotional regulation.

PURPOSE The lack of agreement regarding assessment methods is responsible for the variability in the reported rate of occurrence of unilateral neglect (UN) after stroke. In addition, dissociations have been reported between performance on traditional paper-and-pencil tests and UN in everyday life situations. METHODS In this paper, we present the validation studies of a quantitative test batte...

The surgical procedure used to treat an unruptured intracranial aneurysm (UIA) has controversial effects on cognitive function. From January 2010 through December 2012, we enrolled patients who underwent surgical clipping for a UIA. Patients were tested within one week prior to surgery and again postoperatively (6.8 ± 2.3 days) using a neuropsychological battery comprising the Mini-Mental State...

Contrary to what was originally thought (Hassabis, Kumaran, Vann, & Maguire, 2007) recent data have shown that imagining the future is not entirely dependent on the hippocampus (Squire et al., 2010) and neuroimaging studies have demonstrated a frontopolar activation during future thinking tasks (Okuda et al., 2003). The present study investigated whether the performance of people with Parkinson...

OBJECTIVE We aimed to establish the cut-off point of the Montreal Cognitive Assessment (MoCA-Beijing) in screening for cognitive impairment (CI) within 2 weeks of mild stroke or transient ischaemic attack (TIA). METHODS A total of 80 acute mild ischaemic stroke patients and 22 TIA patients were recruited. They received the MoCA-Beijing and a formal neuropsychological test battery. CI was defi...
