Laser-enhanced cavitation during high intensity focused ultrasound (HIFU) was studied in vivo using a small animal model. Laser light was employed to illuminate the sample concurrently with HIFU radiation. The resulting cavitation was detected with a passive cavitation detector. The in vivo measurements were made under different combinations of HIFU treatment depths, laser wavelengths, and HIFU...

Search tasks, comprising a series of search queries serving a common informational need, have steadily emerged as accurate units for developing the next generation of task-aware web search systems. Most prior research in this area has focused on segmenting chronologically ordered search queries into higher level tasks. A more naturalistic viewpoint would involve treating query logs as convolute...

The heterogeneity of CD4+ T cells has been investigated since the late 1970s, when their Th1 and Th2 subsets were coined. Later studies on the cutaneous form of the Leishmaniasis were focused on the experimental models of Leishmania major infection using the susceptible BALB/c and the resistant C57BL/6 mice. At the early 21st century, the regulatory T-cells subpopulation was introduced and its ...

Previous research has examined the relationship between avatar representation and the sense of presence and co-presence in a shared virtual environment. A positive correlation has been found between the realism of the representation and both categories of presence. However, to our knowledge no research has focused explicitly on the effect of avatar representation in general and connectedness or...

recent versions of international high-stakes tests like toefl and ielts have made use of integrated tasks in addition to the traditional independent tasks in a claim to provide a more realistic estimation of the test takers’ language abilities. the present study aimed to investigate how test takers’ performance may differ on such tasks. as such, the test takers’ performance was compared on ielt...
