Technetium (99mTc) mebrofenin is a radiopharmaceutical used in medical imaging, specifically in hepatobiliary scanning to assess liver and gallbladder function. It is a complex formed by the radiolabeling of mebrofenin, a compound that is a derivative of iminodiacetic acid (IDA).
Technetium (99mTc) fanolesomab is a radiolabeled monoclonal antibody that was developed for diagnostic imaging purposes, particularly in the context of detecting inflammation and certain infections in the body. It binds specifically to the surface receptor CD11b, which is found on the surface of activated leukocytes (white blood cells).
Technetium (99mTc) exametazime, often referred to as Tc-99m exametazime or merely exametazime, is a radiopharmaceutical used in medical imaging, particularly in single-photon emission computed tomography (SPECT) scans. It is a complex of technetium-99m, a radioisotope, with a radiolabeled agent that binds to brain tissues.

Technetium-99m albumin aggregated (99mTc-WBC) is a radiopharmaceutical used in medical imaging, particularly in nuclear medicine. It consists of technetium-99m, a radioactive isotope of technetium, that is bound to aggregated human serum albumin (HSA). The aggregation of albumin enhances its uptake by the reticuloendothelial system, specifically in tissues such as the liver, spleen, and bone marrow.
Sodium pertechnetate (Na^99TcO₄) is a chemical compound that contains the isotope technetium-99 (Tc-99), which is a radioactive element. It is typically found in the form of a sodium salt and has various applications, primarily in the field of nuclear medicine.
Myocardial perfusion imaging (MPI) is a non-invasive diagnostic technique used to assess blood flow to the heart muscle (myocardium). It helps evaluate the presence and severity of coronary artery disease (CAD) by visualizing how well blood is being delivered to different areas of the heart. The procedure typically involves the use of a radioactive tracer, which is injected into the bloodstream. This tracer emits gamma rays that can be detected by a specialized camera, creating images of the heart.
Bectumomab is a monoclonal antibody that was developed for use in the treatment of certain types of cancer, particularly non-Hodgkin lymphoma. It specifically targets the CD19 antigen, which is commonly expressed on the surface of B-cell lymphoid malignancies. By binding to CD19, Bectumomab may help to direct the immune system's response against cancer cells, potentially leading to their destruction.
The Wiener–Ikehara theorem is a result in analytic number theory, which deals with the asymptotic distribution of the partition function \( p(n) \), specifically in relation to the number of partitions of an integer. More formally, it connects the asymptotic behavior of a certain generating function with the distribution of partitions.
A "slowly varying function" is a concept from asymptotic analysis and number theory that refers to a function that grows very slowly compared to a linear function as its argument tends to infinity. More formally, a function \( L(x) \) is said to be slowly varying at infinity if: \[ \lim_{x \to \infty} \frac{L(tx)}{L(x)} = 1 \] for all \( t > 0 \).
Littlewood's Tauberian theorem is a result in the field of mathematical analysis that connects the properties of series (or sequences) and their associated generating functions, specifically in the context of summability methods. The theorem provides conditions under which the convergence of a series can be inferred from the behavior of its generating function, particularly in relation to its analytic properties.
The Hardy–Littlewood Tauberian theorem is an important result in analytic number theory and summability theory. It provides a bridge between the growth conditions of a generating function and the convergence behavior of its associated series. In particular, it establishes conditions under which the summation of a series can be related to the growth of its generating function.
Haar's Tauberian theorem is a result in the field of analytic number theory and harmonic analysis, specifically dealing with summability methods and their connection to convergence of series. The theorem is named after mathematician Alfréd Haar. The basic idea behind Haar's theorem is to establish conditions under which the summation of an infinite series can be deduced from information about the behavior of its partial sums.
Abelian and Tauberian theorems are concepts from mathematical analysis and number theory, specifically related to the convergence of series and the properties of generating functions. Here’s a brief overview of each: ### Abelian Theorem The Abelian theorem typically refers to the Abel's test, which is a criterion for the convergence of series and power series.
A Virtual Tape Library (VTL) is a data storage system that emulates a traditional tape library in a virtualized environment. It is designed to provide the benefits of tape storage while using disk-based storage solutions. Here are some key features and benefits of a VTL: ### Key Features: 1. **Emulation of Physical Tapes**: VTL mimics the behavior of physical tape drives and libraries, allowing existing backup software and systems that rely on tapes to interact with it without modifications.
The Tarbell Cassette Interface is a device designed for use with early microcomputers, particularly those that did not have integrated disk drives. It allows for the storage and retrieval of data on compact cassette tapes, which were a common medium for data storage during the late 1970s and early 1980s.
A tape library is a storage system used to manage and organize magnetic tapes—media that stores data. Tape libraries are typically employed for data backup, archiving, and long-term storage in various computing environments, including data centers and enterprise IT infrastructures. Key features of tape libraries include: 1. **Automation**: Tape libraries often include robotic mechanisms to automatically load and unload tapes into drives, improving the efficiency and speed of accessing data.
A tape drive is a data storage device that uses magnetic tape as a medium for recording and storing data. Originally developed in the 1950s, tape drives have traditionally been used for data backup, archiving, and data transfer due to their high capacity and relatively low cost per gigabyte, especially in large-scale environments.
The TX-2 Tape System was a magnetic tape storage system developed during the early 1960s for the TX-2, a research computer at the Massachusetts Institute of Technology (MIT). The TX-2 itself was notable for its advanced design, including features like word-lengths of 18 bits and floating-point arithmetic, which made it suitable for various complex calculations and simulations.
