Operational Momentum During Ordering Operations for Size and Number in 4-Month-Old Infants

open access: yesJournal of Numerical Cognition, 2017
An Operational Momentum (OM) effect is shown by 9-month-old infants during non-symbolic arithmetic, whereby they overestimate the outcomes to addition problems, and underestimate the outcomes to subtraction problems.

Orbital angular momentum: origins, behavior and applications [PDF]

open access: yes, 2011
As they travel through space, some light beams rotate. Such light beams have angular momentum. There are two particularly important ways in which a light beam can rotate: if every polarization vector rotates, the light has spin; if the phase structure ...

Momentum Has Its Own Values [PDF]

open access: yes, 2021
We find high momentum stocks with preserving substantial \fundamental value" are more likely to rebound after unexpected financial shocks. The portfolio test show that our proposed investment strategy can inherit more portfolio downside risk, especially ...

Intersatellite and Downlink Agile Attitude Maneuvers

open access: yesApplied Sciences, 2023
This research is focused on the problem of agile attitude maneuvering, aimed at the precise pointing of a satellite forming a typical constellation in low Earth orbit. We consider two different operational scenarios: (a) pointing toward a specific ground

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...
