HFE (gene)
Human homeostatic iron regulator protein, also known as the HFE protein (High FE2+), is a protein which in humans is encoded by the ''HFE'' gene. The ''HFE'' gene is located on short arm of chromosome 6 at location 6p22.2 Function The protein encoded by this gene is a membrane protein that is similar to MHC class I-type proteins and associates with beta-2 microglobulin (beta2M). It is thought that this protein functions to regulate circulating iron uptake by regulating the interaction of the transferrin receptor with transferrin. The ''HFE'' gene contains 7 exons spanning 12 kb. The full-length transcript represents 6 exons. HFE protein is composed of 343 amino acids. There are several components, in sequence: a signal peptide (initial part of the protein), an extracellular transferrin receptor-binding region (α1 and α2), a portion that resembles immunoglobulin molecules (α3), a transmembrane region that anchors the protein in the cell membrane, and a short cytoplasmic t ...

H-parameter Model
A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor, uses only one kind of charge carrier. A bipolar transistor allows a small current injected at one of its terminals to control a much larger current flowing between the terminals, making the device capable of amplification or switching. BJTs use two p–n junctions between two semiconductor types, n-type and p-type, which are regions in a single crystal of material. The junctions can be made in several different ways, such as changing the doping of the semiconductor material as it is grown, by depositing metal pellets to form alloy junctions, or by such methods as diffusion of n-type and p-type doping substances into the crystal. The superior predictability and performance of junction transistors quickly displaced the original point-contact transistor. Diffused transistors, along wit ...

Hello From Earth
Active SETI (Active Search for Extra-Terrestrial Intelligence) is the attempt to send messages to intelligent extraterrestrial life. Active SETI messages are predominantly sent in the form of radio signals. Physical messages like that of the Pioneer plaque may also be considered an active SETI message. Active SETI is also known as METI (Messaging to Extra-Terrestrial Intelligence). The term METI was coined by Russian scientist Alexander Zaitsev, who proposed a subtle distinction between Active SETI and METI: In 2010, Douglas A. Vakoch from SETI Institute, addressed concerns about the validity of Active SETI alone as an experimental science by proposing the integration of Active SETI and Passive SETI programs to engage in a clearly articulated, ongoing, and evolving set of experiments to test various versions of the Zoo Hypothesis, including specific dates at which a first response to messages sent to particular stars could be expected. On 13 February 2015, scientists (includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herschend Family Entertainment Corporation
Herschend Family Entertainment (HFE) is a privately owned themed-entertainment company that operates several theme parks and tourist attractions within the United States, and as of 2021, one aquarium in Vancouver, Canada. Founded by Jack and Pete Herschend of Branson, Missouri, in its early years HFE was simply known as Herschend Enterprises. In the 1980s the name was changed to Silver Dollar City Inc., and in 2003, the company gained the current name. HFE is currently headquartered in Peachtree Corners, Georgia. The company's mission is to "Create Memories Worth Repeating” in a manner “consistent with Christian values and ethics.” History HFE traces roots back to Hugo and Mary Herschend from Chicago, Illinois along with sons Jack and Pete. The family vacationed in Missouri's Ozark Mountains region and fell in love with the nature the area offered. In 1951 Hugo obtained a 99-year lease on a Branson, Missouri area attraction called Marvel Cave. Hugo suffered a heart attack ...

Hidden Field Equations
Hidden Fields Equations (HFE), also known as HFE trapdoor function, is a public key cryptosystem which was introduced at Eurocrypt in 1996 and proposed by Jacques Patarin following the idea of the Matsumoto and Imai system. It is based on polynomials over finite fields \mathbb_q of different size to disguise the relationship between the private key and public key. HFE is in fact a family which consists of basic HFE and combinatorial versions of HFE. The HFE family of cryptosystems is based on the hardness of the problem of finding solutions to a system of multivariate quadratic equations (the so-called MQ problem) since it uses private affine transformations to hide the extension field and the private polynomials. Hidden Field Equations also have been used to construct digital signature schemes, e.g. Quartz and Sflash. Mathematical background One of the central notions to understand how Hidden Field Equations work is to see that for two extension fields \mathbb_ \mathbb_ ...

Horizontal Fiscal Equalisation
Equalization payments are cash payments made in some federal systems of government from the federal government to subnational governments with the objective of offsetting differences in available revenue or in the cost of providing services. Many federations use fiscal equalisation to reduce the inequalities in the fiscal capacities of sub-national governments arising from the differences in their geography, demography, natural endowments and economies. The level of equalisation sought can vary, however. The payments are generally calculated based on the magnitude of the subnational "fiscal gap": essentially the difference between fiscal need and fiscal capacity. Fiscal capacity and fiscal need are not equivalent to measures of fiscal revenue and expenditure, as making them so would induce perverse incentives to subnational governments to reduce fiscal effort. Australia Australia introduced a formal system of horizontal fiscal equalisation (HFE) in 1933 to compensate states/territ ...

Human Factors Engineering
Human factors and ergonomics (commonly referred to as human factors) is the application of psychological and physiological principles to the engineering and design of products, processes, and systems. Four primary goals of human factors learning are to reduce human error, increase productivity, and enhance safety, system availability, and comfort with a specific focus on the interaction between the human and the engineered system. The field is a combination of numerous disciplines, such as psychology, sociology, engineering, biomechanics, industrial design, physiology, anthropometry, interaction design, visual design, user experience, and user interface design. Human factors research employs methods and approaches from these and other knowledge disciplines to study human behavior and generate data relevant to the four primary goals above. In studying and sharing learning on the design of equipment, devices, and processes that fit the human body and its cognitive abilities, t ...
