International Journal of Impact Engineering
This study investigates a counterintuitive phenomenon in structural impact, i.e., the peak reaction force exceeds the peak impact force. While the other three counterintuitive phenomena have been collectively documented and studied, this fourth phenomenon was experimentally observed and has not yet been systematically investigated.

BJOG: An International Journal of Obstetrics & Gynaecology, 1996
Objective To assess the relation between peak active (above baseline) head‐to‐cervix force (paHCF) and peak active (above baseline) intrauterine pressure (paIUP) in labour, and to compare the relation between labours progressing well and ending in vaginal delivery and those labours progressing slowly and ending in caesarean section.Design ...

High-speed atomic force microscopy and peak force tapping control
SPIE Proceedings, 2012ITRS Roadmap requires defect size measurement below 10 nanometers and challenging classifications for both blank and patterned wafers and masks. Atomic force microscope (AFM) is capable of providing metrology measurement in 3D at sub-nanometer accuracy but has long suffered from drawbacks in throughput and limitation of slow topography imaging ...

Skyrme force with surface-peaked effective mass
Nuclear Physics A, 2001Abstract By adding to the conventional form of Skyrme force a term with simultaneous momentum and density dependence it is possible to define a new force, labeled SkSP.1, that gives a good fit to the masses of 416 spherical (or near-spherical) nuclei in Hartree–Fock BCS calculations, while having the nuclear-matter value of M ∗ .

Taking Photoacoustic Force into Account in Liquid-Phase Peak Force Infrared Microscopy
The Journal of Physical Chemistry LettersThe microscopic structure of the material's solid-liquid interface significantly influences its physicochemical properties. Peak force infrared microscopy (PFIR) is a powerful technique for analyzing these interfaces at the nanoscale, revealing crucial structure-activity relationships.

Unilateral arm strength training improves contralateral peak force and rate of force development
European Journal of Applied Physiology, 2008Neural adaptation following maximal strength training improves the ability to rapidly develop force. Unilateral strength training also leads to contralateral strength improvement, due to cross-over effects. However, adaptations in the rate of force development and peak force in the contralateral untrained arm after one-arm training have not been ...

Peak Distribution of Random Wave-Current Force
Journal of the Engineering Mechanics Division, 1974When waves encounter current, characteristics of waves, wave field kinematics, and fluid force undergo changes. Evaluation of fatigue damage of marine structures in random fluid field requires knowledge of peak distribution of fluid force. This paper examines the influence of wave-current interactions on peak distribution of fluid force on an element ...

Peak forces in flexible rockfall barriers
2002For the last 14 years flexible rockfall barriers have been improved considerably as far as their energy absorbing capacity is concerned. In design concepts a rock's kinetic energy is compared with the energy absorbing capacity of the retaining structure.

Programming of Time-to-Peak Force for Brief Isometric Force Pulses: Effects on Reaction Time
Quarterly Journal of Experimental Psychology, 2006According to the parallel force unit model (PFUM) the programming of an isometric force pulse requires the specification of the number of force units and force unit duration. The programming of a force pulse with minimal time-to-peak force is an exception, however, as force unit duration is limited by the minimal possible value, which should be easier ...

Ground Reaction Forces and Peak Throwing Shoulder Forces in Softball High School Pitchers
International Journal of Sports MedicineAbstract To optimize pitching performance, pitchers must generate substantial ground reaction forces to aid pitch velocity while minimizing the forces experienced in their throwing shoulder. Extremely high shoulder forces are generally thought to be injurious for softball ...
