Electromagnetic Form Factors of Hadrons in the Space-Like Region
The theory of the strong force is unique amongst the known forces of nature in that the strength of its interactions grow with distance. It is postulated that this leads to the empirically observed colour con nement hypothesis. This hypothesis states that quarks and gluons, the fundamental degrees …

Effect of kinetic degrees of freedom in multi-finger force and moment stabilizing synergies.
… redundance, by investigating the changes in force stabilizing and moment stabilizing synergies for pressing tasks involving different number of fingers (IM, IR, IL, MR, ML, RL, IMR, IML, IRL, MRL, IMRL; where I=Index, M=Middle, R=Ring, L=Little). Twelve healthy right-handed subjects (6 males …

The structure of hadrons and other potential phases of QCD
… particles called quarks and gluons, and the strong force that binds them together into protons and neutrons. This thesis centers on two major thrusts of modern QCD research: (1) uncovering the inner quark and gluon structure of the proton, and (2) mapping out other phases of matter that …

A measurement of the contribution of the gluon to the spin of the nucleon
… of the nucleon from the gluons mediating the strong force within the nucleon. The experimental data was obtained using the HERMES instrument at the Deustches Elektronen-Synchroton (DESY) in Hamburg, Germany during the year 2000. The effort was motivated by an earlier observation at HERMES that …

Exotic charm resonances and coupled-channel scattering from lattice QCD
… describing the electromagnetic, weak and strong forces all under one mathematical framework. Despite its extraordinary success, large parts of the theory remain theoretically poorly understood. In particular, the strong force -- governed by a subset of the standard model called quantum …

Dielectric Elastomer Actuators in Electro-Responsive Surfaces Based on Tunable Wrinkling and the Robotic Arm for Powerful and Continuous Movement
… robotic arms for large deformation and strong force also become desirable for their efficiency, low manufacturing cost, high force-to-weight ratio, and noiseless operation. The DEA-based responsive surfaces in microscale roughness control, however, exhibit limited durability due to …

Evidence for Absence of Latchbridge Formation in Phasic Saphenous Artery
Tonic arterial smooth muscle can produce strong contractions indefinitely by formation of slowly cycling crossbridges (latchbridges) that maintain force at a high energy economy. To fully understand the uniqueness of mechanisms regulating tonic arterial contraction, comparisons have been made to …

The plight of the humanists: a reinterpretation of the battle between the ancients and the moderns
… II in 1660, the new philosophy emerged as a strong force in the quest for knowledge. The new philosophers' vitality encouraged them to denounce human learning and propose the subordination of human learning to the ever-advancing new philosophy. As a result, the humanists staunchly defended …

Measuring the Neutron Spin Asymmetry A1n in the Valence Quark Region in Hall C at Jefferson Lab
… OAM and other non-perturbative effects of the strong force. A1^n was measured in the deep inelastic scattering region of 0.40 < x < 0.75 and 6 < Q^2 < 10 GeV^2 in Hall C at Jefferson Lab using a 10.4 GeV longitudinally polarized electron beam, upgraded polarized He-3 target, and the High …

Self-Esteem in Relation to Gender, Socioeconomic Status, Ethnic/Cultural Origin, Family Characteristics, and Academic Achievement in Middle School Students
… of self-esteem as well as the family acting as a strong force in the development of academic self-esteem. No significant difference was found between the peer self-esteem of males and females from all socioeconomic groups. Students who are home alone after school for extended periods of time tend …

Field Theoretical Approach to the Phases of QCD

The First Laboratory Searches for Low-Mass Axion Dark Matter
