Implied Repo Rate
Implied repo rate (IRR) is the rate of return of borrowing money to buy an asset in the spot market and delivering it in the futures market where the notional is used to repay the loan. Simplified closed form IRR = \left( \frac \text \text -1 \right)\left( \frac \text \text \right) where dayBase is 365 or 360 Usage Determine the cheapest to deliver asset To determine the cheapest bond in a basket of deliverable bonds against a futures contract, implied repo rate is computed for each bond; the bond with the highest repo rate is the cheapest. It is the cheapest because it has the lowest initial value to yield a higher return provided it is delivered with the stated futures price. The net basis between a futures price and its underlying bonds may provide an indication of which bond is the cheapest. However, since the method, unlike the IRR method, neglects the actual running cost of bonds, it is less accurate as a measure for CTD ranking. See also *Official bank rate *Repo ...

Image Rejection Ratio
Image response (or more correctly, image response rejection ratio, or IMRR) is a measure of performance of a radio receiver that operates on the superheterodyne principle. In such a radio receiver, a local oscillator (LO) is used to heterodyne or "beat" against the incoming radio frequency (RF), generating sum and difference frequencies. One of these will be at the intermediate frequency (IF), and will be selected and amplified. The radio receiver is responsive to any signal at its designed IF frequency, including unwanted signals. For example, with a LO tuned to 110 MHz, there are two incoming signal frequencies that can generate a 10 MHz IF frequency. A signal broadcast at 100 MHz (the wanted signal), and mixed with the 110 MHz LO will create the sum frequency of 210 MHz (ignored by the receiver), and the difference frequency at the desired 10 MHz. However, a signal broadcast at 120 MHz (the unwanted signal), and mixed with the 110 MHz LO will create a sum frequency of 230 ...

Infusion-related Reaction
Cytokine release syndrome (CRS) is a form of systemic inflammatory response syndrome (SIRS) that can be triggered by a variety of factors such as infections and certain drugs. It refers to cytokine storm syndromes (CSS) and occurs when large numbers of white blood cells are activated and release inflammatory cytokines, which in turn activate yet more white blood cells. CRS is also an adverse effect of some monoclonal antibody medications, as well as adoptive T-cell therapies. When occurring as a result of a medication, it is also known as an infusion reaction. The term cytokine storm is often used interchangeably with CRS but, despite the fact that they have similar clinical phenotype, their characteristics are different. When occurring as a result of a therapy, CRS symptoms may be delayed until days or weeks after treatment. Immediate-onset CRS is a cytokine storm, although severe cases of CRS have also been called cytokine storms. Signs and symptoms Symptoms include fever that ...

Individual Ready Reserve
The Individual Ready Reserve (IRR) is a category of the Ready Reserve of the Reserve Component of the Armed Forces of the United States composed of former active duty or reserve military personnel. Its governing statute is codified at . For soldiers in the National Guard of the United States, its counterpart is the Inactive National Guard (ING). As of 22 June 2004, the IRR had approximately 112,000 members (does not include all service IRR populations) composed of enlisted personnel and officers, with more than 200 Military Occupational Specialties are represented, including combat arms, combat support, and combat service support. Overview An individual assigned to the IRR typically receives no pay and is not obligated to drill, conduct annual training, or participate in any military activities (except for periodic Muster activities) unless activated by Presidential Reserve Callup Authority or electing to drill, train, or serve in a "Drill without Pay" or an "Active Duty" role.

Incidence Rate Ratio
In epidemiology, a rate ratio, sometimes called an incidence density ratio or incidence rate ratio, is a relative difference measure used to compare the incidence rates of events occurring at any given point in time. It is defined as: : \text = \frac where incidence rate is the occurrence of an event over person-time (for example person-years): : \text = \frac The same time intervals must be used for both incidence rates. A common application for this measure in analytic epidemiologic studies is in the search for a causal association between a certain risk factor and an outcome. See also *Odds ratio *Ratio *Risk ratio The relative risk (RR) or risk ratio is the ratio of the probability of an outcome in an exposed group to the probability of an outcome in an unexposed group. Together with risk difference and odds ratio, relative risk measures the association bet ... References Biostatistics Epidemiology Rates {{statistics-stub ...

Irregular Galaxy
An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure. Collectively they are thought to make up about a quarter of all galaxies. Some irregular galaxies were once spiral or elliptical galaxies but were deformed by an uneven external gravitational force. Irregular galaxies may contain abundant amounts of gas and dust. This is not necessarily true for dwarf irregulars. Irregular galaxies are commonly small, about one tenth the mass of the Milky Way galaxy. Due to their small sizes, they are prone to environmental effects like crashing with large galaxies and intergalactic clouds. Types There are three major types of irregular galaxies: * An Irr-I galaxy (Irr I) is an irregular galaxy that features some structure but not ...

Internet Routing Registry
An Internet Routing Registry (IRR) is a database of Internet route objects for determining, and sharing route and related information used for configuring routers, with a view to avoiding problematic issues between Internet service providers. The Internet routing registry works by providing an interlinked hierarchy of objects designed to facilitate the organization of IP routing between organizations, and also to provide data in an appropriate format for automatic programming of routers. Network engineers from participating organizations are authorized to modify the Routing Policy Specification Language (RPSL) objects, in the registry, for their own networks. Then, any network engineer, or member of the public, is able to query the route registry for particular information of interest. Relevant objects * AUT-NUM * INETNUM6 * ROUTE * INETNUM * ROUTE6 * AS-SET Status of implementation In some RIR regions, the adoption/updates of for e.g. AUT-NUM (Represents for e.g. Autonomous sy ...

Internal Rate Of Return
Internal rate of return (IRR) is a method of calculating an investment’s rate of return. The term ''internal'' refers to the fact that the calculation excludes external factors, such as the risk-free rate, inflation, the cost of capital, or financial risk. The method may be applied either ex-post or ex-ante. Applied ex-ante, the IRR is an estimate of a future annual rate of return. Applied ex-post, it measures the actual achieved investment return of a historical investment. It is also called the discounted cash flow rate of return (DCFROR)Project Economics and Decision Analysis, Volume I: Deterministic Models, M.A.Main, Page 269 or yield rate. Definition (IRR) The internal rate of return on an investment or project is the "annualized effective compounded return rate" or rate of return that sets the net present value of all cash flows (both positive and negative) from the investment equal to zero. Equivalently, it is the interest rate at which the net present value of the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
