Force Attraction Pen

Proceedings of the 2016 CHI Conference Extended Abstracts on Human Factors in Computing Systems, 2016
We present the Force Attraction Pen, a haptic stylus that encourages the users to move in a particular direction by providing variable attraction force feedback based on their actions. The tip of the stylus is augmented with an electromagnet that can repel or attract the stylus to a metallic surface.

Model for an attractive feeble force

Physical Review D, 1989
We present an economical and technically natural model for a scalar feeble force. The scalar couples to ordinary quarks and leptons only through mixing with the ordinary Higgs boson of the standard model. There is therefore a definite prediction for the composition dependence of the force, as well as the qualitative prediction that the physical Higgs ...

Forced Attraction?

Problems of Post-Communism, 2017
The “Bolotnaya” protests of 2011–2013 and the ongoing Ukraine crisis have brought to the forefront of Russian politics an increased preoccupation with soft power. Official discourse and directives seek to both avoid risks and exploit opportunities in using soft power toward state ends. This dichotomous approach to the “power of attraction” demonstrates

Attractive electroviscous forces

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1993
Abstract The electroviscous forces, acting between two equal-sized electrically charged spherical colloidal particles moving in opposite directions through a polar liquid, have been calculated theoretically. It is found that when the spheres meet, an attractive electroviscous force is experienced by each sphere.

Roles of the attractive and repulsive forces in atomic-force microscopy

Physical Review B, 1991
We present a calculation of the attractive (van ver Waals) forces that are to be expected between tips and samples in experiments using atomic-force microscopes and scanning tunneling microscopes, and we discuss the important roles that these attractive forces, and their repulsive counterparts, play in the experiments.

Myeloperoxidase attracts neutrophils by physical forces

Blood, 2011
AbstractRecruitment of polymorphonuclear neutrophils (PMNs) remains a paramount prerequisite in innate immune defense and a critical cofounder in inflammatory vascular disease. Neutrophil recruitment comprises a cascade of concerted events allowing for capture, adhesion and extravasation of the leukocyte.

An attractive force in metastasis

Nature, 2001
In breast-cancer patients, secondary tumours often form in the lungs and bone marrow, for example, but rarely in the kidneys. The explanation for this bias involves soluble attractant molecules called chemokines.

Nucleon size and the attractive nuclear force

Physical Review C, 1987
That the size of a nucleon increases when bound is shown to follow in first order from the attractive nature of the binding potential. We give two simple demonstrations of the connection of size change with the sign of the external potential, the generality of which helps to connect a wide class of successful explanations of medium modifications of the

There Is Neither Attraction nor Attractive Force in Nature

2014
Nothing is found more frequently among physicians and philosophers than the mention of an attractive quality or virtue. Although this word is uttered with haughtiness and arrogance, you will find nothing more absurd if you consider carefully what they mean by attraction. They thus say that there is obviously attraction in Nature, as appears in a magnet
