Society's drive toward ever faster socio-technical systems 1-3 , means that there is an urgent need to understand the threat from 'black swan' extreme events that might emerge 4-19. On 6 May 2010, it took just five minutes for a spontaneous mix of human and machine interactions in the global trading cyberspace to generate an unprecedented system-wide Flash(More)
In this experiment, sensitivity to female facial attractiveness was examined by comparing event-related potentials (ERPs) in response to attractive and unattractive female faces within a study-test paradigm. Fourteen heterosexual participants (age range 18-24 years, mean age 21.67 years) were required to judge 84 attractive and 84 unattractive face images(More)
Previous event-related potential (ERP) and brain imaging studies have suggested observer responses to others’ pain are modulated by various bottom-up and top-down factors, including emotional primes. However, the temporal dynamics underlying the impact of emotional primes on responses to others’ pain remains poorly understood. In the present study, we(More)
The nature of interactions between observing pain in others (other-pain) and subjective pain perception (self-pain) has been debated. To test whether other-pain and self-pain primes increase or decrease responsiveness to complementary self-pain or other-pain targets, two ERP studies were conducted. In Study 1, twenty participants (10 women, 10 men) were(More)
The maternal effect gene swallow ( swa) of Drosophila is required for bicoid and htsN4 mRNA localization during oogenesis. Swallow is also required for additional, poorly understood, functions in early embryogenesis. We have examined the cytoskeleton in swa mutant oocytes and embryos by immunocytochemistry and confocal microscopy. Mid- and late-stage(More)
Summary form only given. Knowing the positions of nodes in sensor networks are essential for many applications. We propose a new method, MDS-MAP(R), that determines the relative positions of nodes based on local distance information. Given a communication path between a starting node and a remote node, the nodes on the path first compute their local(More)
Compressed sensing (CS) can recover sparse signals from under-sampled measurements. In this work, we have developed an advanced CS framework for photoacoustic computed tomography (PACT). During the reconstruction, a small part of the nonzero signals' locations in the transformed sparse domain is used as partially known support (PKS). PACT reconstructions(More)
MiR-125a has been characterized as a tumor suppressor in several cancers. However, the role of miR-125a in cervical cancer is unknown. In this study, we found the expression of miR-125a was downregulated in cervical cancer patients, and negatively correlated with the tumor size, FIGO stage, and preoperative metastasis. Kaplan-Meier analysis showed that(More)
Optical-resolution photoacoustic microscopy is becoming a powerful research tool for studying microcirculation in vivo. Moreover, ultrasonic-array-based optical-resolution photoacoustic computed tomography (OR-PACT), providing comparable resolution at an improved speed, has opened up new opportunities for studying microvascular dynamics. In this Letter, we(More)
