Bovine Papillomavirus
Bovine papillomaviruses (BPV) are a paraphyletic group of DNA viruses of the subfamily ''Firstpapillomavirinae'' of ''Papillomaviridae'' that are common in cattle. All BPVs have a circular genome, circular double-stranded DNA genome. Infection causes warts (papillomas and fibropapillomas) of the skin and alimentary tract, and more rarely cancers of the alimentary tract and urinary bladder. They are also thought to cause the skin tumour equine sarcoid in horses and donkeys. BPVs have been used as a model for studying papillomavirus molecular biology and for dissecting the mechanisms by which this group of viruses cause cancer. Structure and genetic organisation Like other papillomaviruses, BPVs are small non-enveloped viruses with an icosahedral capsid around 50–60 nm in diameter. The capsid is formed of the L1 and L2 structural proteins, with the L1 C-terminus exposed. All BPVs have a circular genome, circular double-stranded DNA genome of 7.3–8.0 kb. The genetic organ ...

Basis Point Value
In finance, basis point value (BPV) denotes the change in the price of a bond given a basis point change in the yield of the bond.Martellini, Priaulet, Priaulet, Fixed-income securities. Wiley Finance, page 169 Basis point value tells us how much money the positions will gain or lose for a 0.01% per annum parallel (i.e. uniform at all durations) movement in the yield curve In finance, the yield curve is a graph which depicts how the yields on debt instruments - such as bonds - vary as a function of their years remaining to maturity. Typically, the graph's horizontal or x-axis is a time line of months or ye .... It is specified for interest rate risk and quantifies the interest rate risk for small changes in interest rates. The basis point value of a bond is roughly proportional to its duration. Notes {{reflist Fixed income analysis Bond valuation ...

Back Porch Video
''Back Porch Video'' was one of the first cable television-based music video programs. It premiered on January 28, 1984 and was created with Russ Gibb, former owner of the Grande Ballroom in Detroit, Michigan. Shown out of Westinghouse Broadcasting, Westinghouse's Group W Cable studios in Dearborn, Michigan, Back Porch Video stayed on the air for the better part of 16 years. What made Back Porch Video unique was that it was crewed and hosted primarily by area high school students; the document of which is found in 2020 on YouTube. The program aired live in Dearborn from 10pm - 1am on Saturday nights. The show expanded to 9pm - 1am after about one year of cablecasting, adding additional hosts. The program saw a short run of three programs broadcast nationwide on Detroit's PBS station WTVS Channel 56. In 1985, Back Porch Video won a CableACE Award.

Bipolar Violation
A bipolar violation, bipolarity violation, or BPV, is a violation of the bipolar encoding rules where two pulses of the same polarity occur without an intervening pulse of the opposite polarity. This indicates an error in the transmission of the signal. T-carrier and E-carrier signals are transmitted using a scheme called bipolar encoding, a.k.a. Alternate Mark Inversion (AMI), where ONE is represented by a pulse, and a ZERO is represented by no pulse. Pulses (which represent ones) always alternate in polarity, so that if, for example two positive pulses are received in succession, the receiver knows that an error occurred (a violation) in that one or more bits were either added or deleted from the original signal. Reliable transmission of data using this scheme requires a regular stream of pulses; too many zero bits in succession can cause a loss of synchronization between transmitter and receiver. To ensure that this is always present, there exist a number of modified AMI code ...
