Infection with mouse adenovirus type 1 (MAV-1) results in fatal acute encephalomyelitis in susceptible mouse strains via infection of brain endothelial cells. Wild-type (wt) MAV-1 causes less brain inflammation than an early region 3 (E3) null virus in C57BL/6 mice. A mouse brain microvascular endothelial cell line infected with wt MAV-1 had higher expression of mRNAs for the proinflammatory ch...

The cellular sites of integration of the avian myeloblastosis-associated virus type 2 (MAV-2) DNA have been examined by Southern blot analysis of cellular DNA from infected cloned and uncloned chicken embryonic fibroblasts. Provirus-cell juncture fragments were not detected in restriction enzyme digests of DNA from MAV-2-infected uncloned cells. However, each MAV-2-infected cell clone examined ...

Tracking a micro aerial vehicle (MAV) is challenging because of its small size and swift motion. A new model was developed by combining compact adaptive search region (SR). The can accurately robustly track MAVs with fast computation speed. SR, which slightly larger than target MAV, less likely to include distracting background large SR; thus, it the MAV. Moreover, SR reduces time tracking be c...

In this article, a dynamic model of a six degrees of freedom (6 DOF) Eight-Rotor MAV (micro aerial vehicles) is derived on the basis of the Newton-Euler formalism. The derivation comprises determining equations of the motion of the Eight-Rotor MAV in three dimensions and approximating the actuation forces through the modelling of aerodynamic coefficients and electric motor dynamics. For Eight-R...

There is a large amount of research currently being done on autonomous micro-aerial vehicles (MAV), such as quadrotor helicopters or quadcopters. The ability to create a working autonomous MAV depends mainly on integrating a simultaneous localization and mapping (SLAM) solution with the rest of the system. This paper provides an introduction for creating an autonomous MAV for enclosed environme...

Mycobacterium avium subsp. hominissuis (MAH) causes disease in both humans and swine; however, the genetic variations in MAH isolates are unclear. The aim of this study was to elucidate the genetic variations in MAH isolates from humans and swine in Japan. We analysed the 16S-23S rDNA internal transcribed spacer (ITS) sequence and variable number of tandem repeats (VNTRs) using the Mycobacteriu...

In this paper, we propose an approach to autonomously control a quadrotor micro aerial vehicle (MAV). With take-off weight of 50 g and 8-min flight endurance, the MAV platform codenamed ‘KayLion’ developed by the National University of Singapore (NUS) is able to perform autonomous flight with pre-planned path tracking. The vision-based autonomous control is realized with a light weight camera s...

We propose a continuous merger activity variable (MAV) as an alternative to discrete industry merger waves. Ranking industries by MAV within a quarter removes the market-wide trend and gives a powerful measure of relative industry stock merger activity that is associated with strong patterns in before and after industry returns and operating performance. During 1989-2015, bucket 1 containing in...

Suspensions of leukemic lymphocytes and myeloblasts and blood of leukemic patients were studied to examine (a) the effect of leukemic cells on blood viscosity and (b) the ability of leukemic cells to traverse channels of capillary diameter. The viscosity of suspensions of leukemic cells was dependent logarithmically on (a) shear strain rate and (b) cytocrit, although, suspensions of small lymph...

OBJECTIVES To describe a large multigenerational family with migraine-associated vertigo (MAV) combining a detailed phenotypic and genetic analysis. BACKGROUND Migraine-associated vertigo is said to be highly prevalent in the general population and, like other migraine syndromes, its etiology is felt to have a strong genetic component. However, so far, there have been no reports of large fami...
