A Low‐Cost, Handheld Optical Stiffness Sensor for Minimally Invasive Surgery
Advanced Robotics Research, EarlyView.A novel handheld stiffness sensor is presented for real‐time tissue stiffness characterization. By simultaneously sensing contact force and tissue deformation, the device enables accurate stiffness quantification without requiring precise manual control. This approach offers a promising solution for intraoperative tumor detection and minimally invasive

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic
Advanced Robotics Research, EarlyView.Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

“Saffar, how many push-ups can you do in 10 seconds?” “I'll show you, T2.” With that exchange, Saffar proceeded to do 15 push-ups as T2 (Terrence Toepker) did the timing. “I think that the upper limit is set by physical principles and not by your strength.” Assuming that you cannot pull yourself down by grabbing the floor, the shortest time down is ...

The Biomechanics of the Push-up
Strength & Conditioning Journal, 2012SUMMARY THE PUSH-UP IS WIDELY USED BY FITNESS PROFESSIONALS TO DEVELOP UPPER-BODY STRENGTH, POWER, AND LOCAL MUSCULAR ENDURANCE. ALTHOUGH THE LOAD DURING A PUSH-UP IS LIMITED BY AN INDIVIDUAL'S BODYWEIGHT AND ANTHROPOMETRY, MANY BIOMECHANICAL VARIATIONS OF THE EXERCISE CAN BE PERFORMED.

For M a finite group, p a prime and S a Sylow p-subgroup of M, consider the following two properties: (P) no non-trivial characteristic subgroup of S is normal in M; (A) \(\bar M/\Phi(\bar M)\cong L_ 2(p^ n)\) for \(\bar M=M/O_ p(M)\) and some positive integer n.

Quadriplegia caused by push-up exercises
Archives of Orthopaedic and Trauma Surgery, 1994This paper describes a case of a 52-year-old male patient with spinal cord injury caused by doing push-up exercises in the prone position. To our knowledge, no previous report has been published describing a case of spinal cord injury caused by push-up exercise. These days, sport is recommended not only to the young but also to older persons.

The pushing up problem for a finite group P is the following: If G is a p-constrained group with \(G/O_ p(G)\cong P\) and \(S\in Syl_ p(G)\), then either find a characteristic subgroup of S normal in G, or describe the structure of G. In the paper under review the author handles a certain generalization of this problem.
