Post-earnings-announcement drift (PEAD) is a phenomenon in financial markets where a company's stock price continues to react to its earnings announcements over a period of time after the announcement has been made, rather than adjusting immediately and completely. This means that after a company releases its earnings report, if the results are significantly better or worse than expected, the stock price may drift upwards or downwards over the following days or weeks as investors continue to process the information and adjust their expectations.

Ciphertext stealing (CTS) is a technique used in cryptography when encrypting data, particularly when data size does not align with the block size of the encryption algorithm being used. In block cipher algorithms, data is processed in fixed-size blocks (e.g., 128 bits for AES). If the plaintext is not a multiple of the block size, padding is typically added to make it fit.

Image processing is a method of performing operations on images to enhance them, extract useful information, or prepare them for analysis or interpretation.

The Journal of the Korean Astronomical Society (JKAS) is a scientific journal that publishes research in the field of astronomy and astrophysics. It is the official journal of the Korean Astronomical Society and typically features peer-reviewed articles, research papers, and reviews covering a wide range of topics related to astronomy, including observational studies, theoretical analyses, and advancements in astronomical techniques. The journal aims to promote the exchange of knowledge among astronomers and astrophysicists, both within Korea and internationally.

The term "Hubble bubble" refers to a large, somewhat spherical region of space that exhibits a lower density of galaxies and other cosmic structures compared to the surrounding universe. This phenomenon is associated with the Hubble Space Telescope and relates to the observation of cosmic expansion. In the context of cosmology, the Hubble bubble is typically discussed in relation to the Hubble flow, which describes how galaxies are observed to be moving away from each other as the universe expands.

As of my last knowledge update in October 2023, "Autapse" does not refer to a widely recognized term in scientific literature or popular culture. However, it is possible that it could refer to a specific concept, product, technology, or niche subject in fields like neuroscience, artificial intelligence, or perhaps even a brand or software that has emerged after my last update.

Dendritic spines are small, protruding structures found on the dendrites of neurons. They serve as the primary sites for synaptic transmission and are critical for neural communication and plasticity. Each spine forms a synapse with an axon terminal from another neuron, allowing for the transfer of signals across the synapse. Dendritic spines vary in shape and size, and their morphology can change in response to neural activity, a phenomenon known as synaptic plasticity.

The Modular Ocean Model (MOM) is a widely used numerical model for simulating ocean circulation and climate systems. It was developed to provide researchers and scientists with tools to understand oceanographic processes and their interactions with the atmosphere, ice, and land systems. Key features of the Modular Ocean Model include: 1. **Modularity**: The "modular" aspect refers to the model's flexible design, which allows different components or modules to be added, modified, or replaced.

The Regional Atmospheric Modeling System (RAMS) is a complex numerical model used for simulating and forecasting atmospheric conditions at regional scales. It is primarily designed to investigate and predict the behavior of atmospheric phenomena, such as weather systems, air quality, and climate variations, with a higher resolution than global models can provide.

A laser level is a tool used in construction, surveying, and various other industries to establish a straight and level reference line or point. It employs a laser beam to project a line or dot onto a surface, allowing users to accurately measure and align installations, such as cabinets, shelves, or flooring. ### Types of Laser Levels: 1. **Line Laser Levels**: Projects a straight line of laser light along a horizontal or vertical plane. These are useful for tasks like aligning cabinets or marking walls.

Zettascale computing is a term that describes computing systems capable of processing, storing, and analyzing data on the scale of zettabytes, which is 10^21 bytes or one sextillion bytes. As data generation increases exponentially from sources like the Internet of Things (IoT), social media, enterprise applications, and scientific research, there is a growing need for computational frameworks that can efficiently manage and derive insights from such vast amounts of information.

BPCS (Bitmap Combination Pattern Steganography) is a method of covertly embedding information within bitmap images. This technique takes advantage of the way digital images are stored, manipulating the pixel values in a way that the changes are imperceptible to human viewers. The primary goal of BPCS-steganography is to hide data within an image in such a manner that it remains undetectable by casual examination.
