"The function of lateral line organ system of jack mackerel (Trachurusjaponicus) was studied through histological observations, for identifying the structure and distribution of lateral line organs both for the head part and body trunk, with the identification of the histological details of pores and hair cells. Histological observations were conducted with a binocular microscope, with three different approaches as haematoxylin, methylene blue and di-4-ASP dye for identifying the structure and distribution of lateral line organs, and then to identify the histological details of pores and hair cells by preparing the sampled tissue for photo-microscopic observations. The results showed that seven canal systems were identified in the head part; such as supra temporal, postoptic, optic, supra orbital, infra orbital, operculum and mandibular canals, with the width ranging 0.9-1.5 mm. Higher density of pore distribution was examined on the nasal and dorsal areas of the head part, which is 7-8 and 5 pores/mm2 respectively. In the other areas of the head part, the density of pores was ranged as 1-2 pores/mm2. Concerning the body trunk, 29 pores of 12-13 pm diameters were identified along the main lateral line. The functions of lateral line organ of jack mackerel are discussed in relation to the swimming behaviour and performance."

""Copper accumulation and development of nephrocyte in the gill of the shrimp Penaeus japonicus.The effect of sublethal concentrations of copper on the gills copper accumulation and the development of nephrocytes has been studied in juvenile Penaeus japonicus. The copper concentration increased in the gills according to the external copper concentration and the exposure time. The high development of nephrocytes was occurred in the gills of shrimps exposed to 100 ug Cu L-1. In the gills of shrimps exposed to 500 and 1000 ug Cu L-1. The size of nephrocyte was bigger than that of the controls.""

"This book presents a comprehensive review of the recent developments in fast L1-norm regularization-based compressed sensing (CS) magnetic resonance image reconstruction algorithms. Compressed sensing magnetic resonance imaging (CS-MRI) is able to reduce the scan time of MRI considerably as it is possible to reconstruct MR images from only a few measurements in the k-space; far below the requirements of the Nyquist sampling rate. L1-norm-based regularization problems can be solved efficiently using the state-of-the-art convex optimization techniques, which in general outperform the greedy techniques in terms of quality of reconstructions. Recently, fast convex optimization based reconstruction algorithms have been developed which are also able to achieve the benchmarks for the use of CS-MRI in clinical practice. This book enables graduate students, researchers, and medical practitioners working in the field of medical image processing, particularly in MRI to understand the need for the CS in MRI, and thereby how it could revolutionize the soft tissue imaging to benefit healthcare technology without making major changes in the existing scanner hardware. It would be particularly useful for researchers who have just entered into the exciting field of CS-MRI and would like to quickly go through the developments to date without diving into the detailed mathematical analysis. Finally, it also discusses recent trends and future research directions for implementation of CS-MRI in clinical practice, particularly in Bio and Neuro-informatics applications."
