An Efficient ISAR Imaging Method for Multiple Targets
This paper proposes an efficient method to obtain TSAR images of multiple targets flying in formation. The proposed method improves the coarse alignment and segmentation of the existing method. The improved coarse alignment method models the flight trajectory using a combination of a polynomial and Gaussian basis functions, and the optimum parameter of the trajectory is found using particle swarm optimization. In the improved segmentation, the binary image of the bulk TSAR image that contains all targets is constructed using a two-dimensional constant false alarm detector, then the image closing method is applied to the binary image. Finally, the connected set of binary pixels is used to segment each target from the bulk image. Simulations using three targets composed of point scattering centers and the measured data of the Boeing747 aircraft prove the effectiveness of the proposed method to segment three targets flying in formation.X113Ysciescopu

In vitro embryo rescue for the production of hypotetraploids after cross between hypotetraploid and tetraploid grape cultivars
Consumer demand for seedless grape with high quality and large berry has been increasing. Breeding of hypotetraploid grape was suggested as one of promising methods to satisfy it, but low frequency of hypotetraploid occurrence and low seed germination by abortive embryo were indicated as the major problem to hamper the development of hypotetraploid grape. Hence, this study was carried out to evaluate the basic efficiency of in ovulo embryo culture after the cross between hypotetraploid (‘Hanareum’) and tetraploid (‘Honey Black’ and ‘Kyoho’) grape cultivars on the establishment of hypotetraploid grapes. Embryos and plantlets were hardly obtained in ovules cultured at six after the cross pollination (WAP), but ovules inoculated at 10 WAP produced more embryos as well as plantlets regardless of cross combination. Furthermore, we found that embryo formation was not affected by the basal media in ovules cultured at six WAP, but utilization of specific medium can be more beneficial for embryo formation when ovules were cultured at 10 WAP. A total of 17 plants were obtained from ovules cultured at 10 WAP, and above 50% of plants were identified as hypotetraploid grapes. These results indicate that in vitro embryo rescue after cross pollination between hypotetraploid and tetraploid grape can enhance the efficiency for the breeding of hypotetraploid grapes
Animal Assisted Intervention for Rehabilitation Therapy and Psychotherapy
Animal-assisted Intervention (AAI) is a goal-oriented intervention that intentionally includes or incorporates animals in health, education, and human service for the purpose of therapeutic gains in humans. AAI incorporates human-animal teams in formal human service such as Animal-assisted Therapy (AAT) or Animal-assisted Education (AAE). Animal-assisted Activity (AAA) is the informal AAI often conducted on a volunteer basis by the human-animal team for motivational, educational, and recreational purposes. AAI could be used for rehabilitation therapy and psychotherapy for patients with various symptoms. AAI uses animals, mostly dogs, to aid in healing patients holistically. Dogs have an overwhelming gratitude and exuberance for life and this effect on people is astounding. Furthermore, AAI has been researched and its effectiveness on patients’ outcomes and healing is documented. With a soaring trend of the incorporation of complementary therapies into the mainstream of therapy and health care, animal-facilitated therapy has become a popular interest for the therapy team to integrate into a patient’s plan of therapy
Necrotizing fasciitis involving the chest and abdominal wall caused by Raoultella planticola
<p>Abstract</p> <p>Background</p> <p><it>Raoultella planticola </it>was originally considered to be a member of environmental <it>Klebsiella</it>. The clinical significance of <it>R. planticola </it>is still not well known.</p> <p>Case presentation</p> <p>We describe the first case of necrotizing fasciitis involving the chest and abdominal wall caused by <it>R. planticola</it>. The identity of the organism was confirmed using 16S rRNA sequencing. The patient was successfully treated with the appropriate antibiotics combined with operative drainage and debridement.</p> <p>Conclusions</p> <p><it>R. planticola </it>had been described as environmental species, but should be suspected in extensive necrotizing fasciitis after minor trauma in mild to moderate immunocompromised patients.</p
