The Role of Thyrotropin-Releasing Hormone Stimulation Test in Management of Hyperthyrotropinemia in Infants.

Journal of clinical research in pediatric endocrinology
OBJECTIVE: Hyperthyrotropinemia, which can be either a permanent or a transient state, is an asymptomatic condition and there is a controversy in management and long-term consequences. The aim of this study was to evaluate the results of thyrotropin-...

New results for global exponential synchronization in neural networks via functional differential inclusions.

Chaos (Woodbury, N.Y.)
This paper is concerned with the synchronization dynamical behaviors for a class of delayed neural networks with discontinuous neuron activations. Continuous and discontinuous state feedback controller are designed such that the neural networks model...

Aortic Annulus Diameter Affects Durability of the Repaired Bicuspid Aortic Valve.

The Journal of heart valve disease
BACKGROUND AND AIM OF THE STUDY: An investigation was made as to whether the preoperative aortic annular diameter affects the durability of bicuspid aortic valve (BAV) repair in patients who had undergone concomitant root stabilization with subcommis...

Robotic Low Ligation of the Inferior Mesenteric Artery for Rectal Cancer Using the Firefly Technique.

Yonsei medical journal
PURPOSE: By integrating intraoperative near infrared fluorescence imaging into a robotic system, surgeons can identify the vascular anatomy in real-time with the technical advantages of robotics that is useful for meticulous lymphovascular dissection...

Robotic real-time translational and rotational head motion correction during frameless stereotactic radiosurgery.

Medical physics
PURPOSE: To develop a control system to correct both translational and rotational head motion deviations in real-time during frameless stereotactic radiosurgery (SRS).

Robots that can adapt like animals.

Nature
Robots have transformed many industries, most notably manufacturing, and have the power to deliver tremendous benefits to society, such as in search and rescue, disaster response, health care and transportation. They are also invaluable tools for sci...

Reinforcement learning improves behaviour from evaluative feedback.

Nature
Reinforcement learning is a branch of machine learning concerned with using experience gained through interacting with the world and evaluative feedback to improve a system's ability to make behavioural decisions. It has been called the artificial in...

Laparoscopic Total Gastrectomy for Remnant Gastric Cancer Following Distal Gastrectomy with Radical Lymphadenectomy.

Hepato-gastroenterology
BACKGROUND/AIMS: In cases of remnantgastric cancer (RGC) with previous lymphadenectomy, laparoscopic total gastrectomy (LTG) is still uncommon because of the technical difficulties associated with adhesions from previous gastric cancer surgery and va...

A method for volumetric imaging in radiotherapy using single x-ray projection.

Medical physics
PURPOSE: It is an intriguing problem to generate an instantaneous volumetric image based on the corresponding x-ray projection. The purpose of this study is to develop a new method to achieve this goal via a sparse learning approach.

A universal concept based on cellular neural networks for ultrafast and flexible solving of differential equations.

IEEE transactions on neural networks and learning systems
This paper develops and validates a comprehensive and universally applicable computational concept for solving nonlinear differential equations (NDEs) through a neurocomputing concept based on cellular neural networks (CNNs). High-precision, stabilit...
