lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Nursing Code of Ethics

Nursing Code of Ethics

The Nursing Code of Ethics sets the ethical benchmark for the profession, and guides nurses in ethical analysis and decision making at the societal, organizational, and clinical levels. The code encompasses showing compassion and respect for the patient, their families, and communities in all circumstances while committing to providing patient-centered care. In addition, the code states that nurses must advocate for the patient by defending a cause or recommendation to protect their rights,...

Cable Subjected to Its Own Weight

Cable Subjected to Its Own Weight

Overhead power transmission lines rely on cables to carry electricity across large distances. To ensure the stability and functionality of these lines, it is crucial to understand the shape and tension experienced by the cables under the influence of their weight.
A generalized loading function is employed to analyze a cable subjected to its own weight. This function considers the force acting along the cable's arc length rather than its projected length, providing a more accurate...

Cable Subjected to Concentrated Loads

Cable Subjected to Concentrated Loads

Flexible cables are commonly used in various applications for support and load transmission. Consider a cable fixed at two points and subjected to multiple vertically concentrated loads. Determine the shape of the cable and the tension in each portion of the cable, given the horizontal distances between the loads and supports.

Cable Subjected to a Distributed Load

Cable Subjected to a Distributed Load

The analysis of suspension bridges is a complex and critical process that involves multiple factors, including the shape and tension of the main cables. The main cables of suspension bridges are subjected to distributed loads, which result in changes in tensile forces and deformation of the cable. These loads must be carefully considered to ensure that the bridge is safe and capable of supporting the weight of different loads.

Area of Science:

Cognitive neuroscience
Decision science
Computational psychiatry

Background:

Preference-based decisions are vital for survival but exhibit unexplained variability and irrationality.
Existing models struggle to mechanistically explain the nuances of subjective valuation.

Purpose of the Study:

To propose and validate an inference-based model for subjective valuation.
To explain variability in value reports, choices, and confidence levels.
To provide a unified account of environmental perception and behavior guidance.

Main Methods:

Developed a computational model of inference that maximizes information under coding constraints.
Validated the model's predictions against empirical data, including a novel preference illusion.
Analyzed subjective value reports, choice data, and confidence ratings.

Main Results:

The proposed inference model successfully explains preference variability and choice patterns.
The model predicts and validates a new preference illusion.
The model also accounts for the confidence associated with subjective reports.

Conclusions:

Subjective valuation is an information-maximizing inference process adapting to environmental value structures and coding limitations.
This framework offers a unified explanation for perception, valuation, and behavior optimization.
Findings suggest decisions reflect statistically optimal decoding within a limited-capacity system.
