A technic of measuring left ventricular coronary blood flow in dogs and man from the rate of desaturation of nitrous oxide from the myocardium is presented. The desaturation technic appears valid in comparison with the previously described saturation technic, and affords definite technical advantages. By combining the two technics, flows may be measured within much less time than by repeating e...

We describe the case of a 65-year-old man who presented with a false aneurysm of the right aortic coronary sinus, discovered after a routine medical examination. A complete resection of the aortic root and a reimplantation technique were performed. Herein, we describe the technical approach and immediate follow-up.

“Our [power] plant no longer needs imported equipment or skills. ...Recalling the past, [veteran machinery maintenance man] Lu said, ‘Under imperialist control, all important technical data was withheld from Chinese workers. ...Today all the technology is in our hands. And we run our plant ten times better than the imperialists!’” “Shanghai’s biggest power plant—then and now,” China Reconstruct...

Given the frequency of the disease and the difficulty of tumor resections, image-guided surgery technologies may aid the surgical management of prostate cancer patients. The "from molecule to man" translation of such approaches is, however, complex and depends on many different features, both from a technical and a practical perspective.

We construct a simple authentication protocol whose security is based solely on the problem of Learning Parity with Noise (LPN) that is secure against Man-in-the-Middle attacks. Our protocol is suitable for RFID devices, whose limited circuit size and power constraints rule out the use of more heavyweight operations such as modular exponentiation. The protocol is extremely simple: both parties ...

As Cuban–Soviet relations strengthened throughout the 1960s, Havana sent a significant number of becarios (scholarship holders) to USSR. This was intended improve Cuba’s technical advancement, but it also part broader attempt build, through education, what Ernesto ‘Che’ Guevara coined as ‘Cuban New Man’. To ensure students’ adherence socialism and avoid dissatisfaction with revolution, Cuban le...

our aim was to report techniques and our experience in one-stage angioplasty and stenting of ostium of left common carotid and left internal carotid arteries in an octogenarian man with transient ischemic attack, who was completely recovered from neurologic insults short time after the procedure. an 81-year-old man presented with a transient ischemic attack. neurologic examination showed left s...
