Concurrency semantics refers to the set of principles and rules that govern the behavior of concurrent systems—systems where multiple processes or threads operate independently and potentially simultaneously. In computer science, particularly in the context of programming languages, operating systems, and distributed systems, concurrency semantics defines how operations interact when executed concurrently.

Proof-carrying code (PCC) is a formal method used in computer science, particularly in the field of software verification and security. The concept involves attaching a formal proof to a piece of code which guarantees that the code adheres to specific safety and security properties. Here’s a high-level overview of how it works: ### Key Concepts: 1. **Code and Proof**: When a developer writes code, they also generate a proof that the code satisfies certain properties.

George Johnson is an American writer and science journalist known for his work on topics related to science, especially space and the natural world.

Hubert Dreyfus (1929–2017) was an influential American philosopher and a prominent figure in the fields of existentialism, phenomenology, and the philosophy of technology. He was best known for his critiques of artificial intelligence and his interpretations of the works of existentialist philosophers, particularly Martin Heidegger, Jean-Paul Sartre, and Maurice Merleau-Ponty.

As of my last update in October 2021, there isn't widely recognized information about someone named Jessica Wahman. It's possible that she could be a private individual or a rising figure in a specific field after that time. If you have more context about who she is or what she is associated with, I could provide better assistance.

Lucy O'Brien is a prominent philosopher known for her work in the fields of feminist philosophy, philosophy of mind, and ethics. She has made significant contributions to the understanding of personal identity, moral responsibility, and the nature of self. O'Brien is often recognized for her explorations of how gender and social constructs influence our understanding of self and identity. Her writing might include discussions on the role of emotions in moral philosophy, as well as the philosophical implications of feminist issues.

ICME stands for Integrated Computational Materials Engineering, which is a field that focuses on the development and application of computational methods and tools to analyze and predict material behavior across multiple scales, from atomic to macroscopic levels. The concept of ICME cyberinfrastructure encompasses the computational resources, tools, software, and data management practices that facilitate research and development in this area.

e-Science infrastructures refer to the advanced digital frameworks and resources that support scientific research through the use of computing and information technologies. These infrastructures facilitate collaboration, data sharing, and various computational tasks across disciplines. Below is a list of notable e-Science infrastructures: 1. **GRID Computing** - **Open Science Grid (OSG)**: A resource for scientific research that provides a distributed computing environment.

MATHUSLA (Massive Absence of THresholL for Ultra-stable particles) is a proposed experiment designed to search for very light, long-lived particles that might be produced at high-energy particle colliders like the Large Hadron Collider (LHC). These particles could be candidates for dark matter or other new physics beyond the Standard Model.

GPGPU stands for General-Purpose computing on Graphics Processing Units. It refers to the use of a GPU (Graphics Processing Unit) to perform computation that is traditionally handled by the CPU (Central Processing Unit). GPGPU libraries are specialized software libraries designed to facilitate general-purpose computing on GPUs by providing tools, frameworks, and APIs to enable developers to leverage the parallel processing capabilities of GPUs for non-graphics workloads.

Graphics Core Next (GCN) is an architecture developed by AMD (Advanced Micro Devices) for its family of GPUs (graphics processing units). Introduced in 2011 with the AMD Radeon HD 7000 series, GCN represents a significant evolution in GPU design, focusing on compute performance, efficiency, and flexibility for various applications, including gaming, professional visualization, and compute workloads.

Single Instruction, Multiple Threads (SIMT) is a parallel computing architecture used primarily in graphics processing units (GPUs) and other such highly parallel computing environments. SIMT is closely related to Single Instruction, Multiple Data (SIMD), but with a key distinction that allows for more flexibility in thread execution. Here’s a breakdown of the key concepts: ### SIMT Characteristics: 1. **Single Instruction**: In SIMT, a single instruction is issued to multiple threads for execution.

The term "digital manifold" can refer to several concepts depending on the context in which it is used, particularly in fields like mathematics, computer science, and data science. Here's a brief overview of its usage: 1. **Mathematics and Geometry**: In mathematical terms, a manifold is a topological space that locally resembles Euclidean space. A "digital manifold" can refer to a discrete approximation of these structures, often used in computational geometry.

Women cryptographers are female individuals who have made significant contributions to the field of cryptography, which is the study and practice of techniques for securing communication and information from adversarial parties. Throughout history, numerous women have played vital roles in the development of cryptographic methods, the breaking of codes, and the advancement of secure communication technologies. Some notable women in cryptography include: 1. **Elizebeth Smith Friedman**: A pioneer in the field, she worked on cryptanalysis for the U.S.

Acoustic cryptanalysis is a technique used to extract cryptographic keys from devices by analyzing the sounds they make during operations. This method capitalizes on the acoustic emissions that result from electronic device activities, such as key presses on a keyboard or the operations of a computer's processor. The basic premise of acoustic cryptanalysis is that when a device performs cryptographic operations, it may generate subtle sounds that can reveal information about the keys being used.

A Birthday attack is a type of cryptographic attack that takes advantage of the mathematics behind the birthday problem in probability theory. It has implications for various cryptographic algorithms, particularly those that involve hash functions. ### How the Birthday Attack Works: 1. **Birthday Paradox**: The birthday problem refers to the counterintuitive probability that in a group of people, the chance that at least two people share a birthday is surprisingly high, even for a small group.

Vladimir Solovyov (1853–1900) was a prominent Russian philosopher, theologian, and poet known for his significant contributions to the fields of philosophy and religious thought. He is often regarded as a central figure in Russian religious philosophy and is known for his attempts to synthesize various philosophical and theological ideas, particularly those stemming from Orthodox Christianity.

Vasile Pogor was a Romanian writer, teacher, and politician, primarily known for his contributions to Romanian literature and his role in the cultural life of the 19th century. He was associated with various literary movements and was known for his involvement in the development of Romanian prose and poetry. His works often reflect the social and political issues of his time, and he played a part in the Romanian national renaissance.

A correlation attack is a type of statistical attack that is commonly used in cryptanalysis to exploit weaknesses in cryptographic algorithms, particularly those that involve block ciphers or stream ciphers. The fundamental idea behind a correlation attack is to take advantage of the statistical relationships between certain input and output variables. In simpler terms, the attacker looks for patterns in the encrypted data and attempts to correlate these patterns with the plaintext (the original unencrypted data) to recover secret keys or uncover sensitive information.
