Yttrium fluoride YF3 layer with different coating contents is successfully covered on the surface of Li1.2Mn0.54Ni0.13Co0.13O2 via a common wet chemical approach. The XRD, SEM, TEM, and charge-discharge tests are applied to investigate the influence of YF3 layer on the micro-structural, morphology, and electrochemical properties of Li1.2Mn0.54Ni0.13Co0.13O2. And the electrochemical test results demonstrate...
Background Relapse of acute lymphoblastic leukemia (ALL) occurring in the breast after allografting is extremely rare, with only 22 reported cases in the literature thus far. Further, the lack of a systemic analysis provides little information about this entity. We present a case of isolated extramedullary relapse from acute T lymphoblastic leukemia (ATLL) after allogeneic hematopoietic stem cell...
Male breast carcinoma (MBC) is rarely encountered in clinical practice. Due to its paucity, our knowledge of MBC only rely on small or single-institutional studies and sporadic cases. The current guidelines for MBC are extrapolated from its female counterparts Rudlowski (Breast Care (Basel) 3(3):183–189, 2008). Nowadays, MBC is actively studied and viewed as a potentially different entity on the aspects...
Autonomous underwater vehicles (AUV) are unmanned underwater robots. They are always used to investigate sea environments, oceanography and deep-sea resources autonomously. Navigation of underwater vehicles is a very demanding task, especially in dynamic environment, which has great reflection on ocean current. In order to avoid different risk and to save energy, the path of AUV is usually calculated...
Swarm Intelligence inspired by social animals has gained a lot of attention recently. It always appeals to the collective behaviors observed in social animals. In this paper, a mean field model of rescue process in robotic system is given and its dynamic with noise and emergency ability is implemented by Monte Carlo type of simulation.
As for the increasing complexity of AUV missions, more reliable and robust abilities of AUV system are required. After introducing the classical control system of AUV, the paper presents a layered self-healing architecture, and a mechanism based on micro-reboot which is applied to self-healing process. This work aims to develop an architecture on how to provide a stable and continued implementation...
Swarm Intelligence which is inspired by social animals has gained a lot of attention recently. It always appeals to the collective behaviors observed in social animals. Foraging behavior in ant colonies have come to be viewed as a prototypical example of how complex group behavior can arise from simple individuals. In this paper, foraging process with two sources observed in ant system is simulated...
Reactive control has the character of flexibility and timeliness. Aimed at the formation control of multiple robots, this paper presents a behavior-based method on it. In the process of moving to the goal, the robots take the leader-referenced technique. And the dynamic-dead-zone method is used to maintain the formation predetermined. The combination of potential-based avoidance and following-wall...
