Newton's Law of Universal Gravitation

2023
Source: Ketron Mitchell-Wynne, PhD, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA Legend states that Isaac Newton saw an apple fall from a tree. He noticed the acceleration of the apple and deduced that there must have been a force acting upon the apple. He then surmised that if gravity can act at the top of the tree, it can also act at even larger distances. He observed the motion of the moon and the orbits of the...

Light from astronomical objects must travel through the earth's turbulent atmosphere before it can be imaged by ground-based telescopes. To enable direct imaging at maximum theoretical angular resolution, advanced techniques such as those employed by the Robo-AO adaptive-optics system must be used.

2010
This procedure describes a quick and easy workflow to introduce siRNA into difficult to transfect cell lines and follow gene expression by real-time PCR. Use of an automated cell counter, multi-well electroporation plate, and automated electrophoresis station provide quick and reliable results without the need for expensive robotic handling.

Qualitative and Quantitative Validation of Tools with Rating Scales Aimed at Assessing the Quality of University Service-Learning
0 Views •
2025
This paper outlines the protocol for qualitatively and quantitatively validating a university service-learning instrument, following the parsimony criterion to create the most robust and optimal version possible. The Delphi qualitative validation method and Robust Unweighted Least Squares Exploratory Factor Analysis, as a quantitative item optimization method, are utilized for this purpose.

2017
Methods for generating large-scale gRNA libraries should be simple, efficient and cost-effective. We describe a protocol for the production of gRNA libraries based on enzymatic digestion of target DNA. This method, CORALINA (comprehensive gRNA library generation through controlled nuclease activity) presents an alternative to costly custom oligonucleotide synthesis.
FAQs
Recognition depends on coordinated changes across the face, voice, body posture, and attention rather than on a single isolated cue. These channels can provide converging information about an emotional state, helping observers interpret signals during social interaction. Studying their coordination allows psychologists to examine how emotion communication operates across different forms of human behavior.
Display rules can influence when, how strongly, and in which social situations people show an emotion, even when the underlying signal is recognizable across cultures. This distinction helps researchers separate the possible cross-cultural pattern of an expression from culturally shaped regulation of its use, improving interpretation of findings about emotional communication.
Researchers examine whether observers identify basic emotional states from facial, vocal, or bodily signals without relying on shared spoken language. Consistent recognition across diverse cultural groups would support the idea that some expression patterns are broadly interpretable. Variation in recognition can also reveal how cultural experience and social perception shape emotional understanding.
A cross-cultural investigation compares how people from diverse cultural backgrounds interpret facial, vocal, or bodily signals associated with emotions such as happiness, fear, anger, sadness, surprise, and disgust. Researchers focus on whether observers identify similar emotional states despite different languages and cultural experiences. The resulting comparisons inform debates about shared and culturally shaped communication.
These studies show how people extract emotional information from visible, vocal, and bodily behavior during social interaction. Their findings can clarify how observers interpret others, how empathy may be supported by recognizable signals, and how communication proceeds across cultural boundaries. They also help connect emotion research with broader questions about interpersonal understanding.
Research on these signals provides a framework for examining situations in which people have difficulty identifying emotional states in others. Comparing recognition of facial, vocal, or bodily cues can indicate which aspects of emotional communication are affected. This relevance connects basic research on expression and perception with psychological questions about social interaction and empathy.
