Positron emission tomography (PET) and computed tomography (CT) scanner image analysis plays an important role in clinical radiotherapy treatment.PET and CT images provide complementary cues for identifying tumor tissues.In specific, PET images can clearly denote the tumor tissue, whereas this source suffers from the problem of low spatial resoluti
Macroalgae is the dominant trophic group on Mediterranean infralittoral rocky bottoms, whereas zooxanthellate corals are extremely rare.However, in recent years, the Reversing Camera Accessory invasive coral Oculina patagonica appears to be increasing its abundance through unknown means.Here we examine the pattern of variation of this species at a
Gel becomes an important class of soft materials since it can be seen in a wide variety of the chemical and the biological systems.The unique properties of gel arise from the structure, namely, the three-dimensional polymer network that is swollen by a huge amount of solvent.Despite the small volume fraction of the polymer network, which is usually
Compared to the normal tissues, cancer cells tend to have higher proliferation rate and often lost their ability to undergo apoptosis.In addition, cancer cells can separate themselves from their original tissue thus causing metastasis in other part of body.While undergoing program cell death, disordered cellular programming can happen.The main caus
A mobile ad hoc network (MANET) is a set of mobile, decentralized, and self-organizing nodes that are used in special cases, such as in the military.MANET Tool properties render the environment of this network vulnerable to different types of attacks, including black hole, wormhole and flooding-based attacks.Flooding-based attacks are one of the mo
