Significant Power Consumption Reduction and Speed Boosting in Phase Change Memory with Nanocurrent Channels.

The excessive power consumption is challenging for phase change memory (PCM) on its way to becoming universal memory in complex hierarchies of memory systems. Here, from the perspective of device structure, by adding a nanocurrent-channel (NCC) layer between the electrode layer and phase change layer, a RESET power consumption reduction by more than 95% and 10 times faster SET speed were realized simultaneously. Through the first principle calculations, Au and SiO were screened as the metal and insulating matrix material of NCC layer, respectively.

Evaluative Skill in the Creative Process: A Cross-cultural Study.

Evaluative skill is the ability to accurately judge ideas on creativity (or originality), which is a critical component of creativity. Various aspects of creativity have been examined cross-culturally, but little research has focused on evaluative skill. The first goal of this study was to examine the measurement invariance of evaluative skill assessments, which were based on two types of divergent thinking tests (Line Meanings and Uses), between American ( = 341) and Chinese ( = 345) college students.

Herbicidal and Antifungal Xanthone Derivatives from the Alga-Derived Fungus D5.

Fungi have been proved as promising and prolific sources of functional secondary metabolites with potent agricultural applications. In this study, 14 xanthone derivatives (-), including six new ones, versicones I-N (, , ), and a biogenetically related derivative (), were isolated from the alga-derived fungus D5. Their structures were elucidated by comprehensive spectroscopic methods.
