Long-term Potentiation
In neuroscience, long-term potentiation (LTP) is a persistent strengthening of synapses based on recent patterns of activity. These are patterns of synaptic activity that produce a long-lasting increase in signal transmission between two neurons. The opposite of LTP is long-term depression, which produces a long-lasting decrease in synaptic strength. It is one of several phenomena underlying synaptic plasticity, the ability of chemical synapses to change their strength. As memories are thought to be encoded by modification of synaptic strength, LTP is widely considered one of the major cellular mechanisms that underlies learning and memory. LTP was discovered in the rabbit hippocampus by Terje Lømo in 1966 and has remained a popular subject of research since. Many modern LTP studies seek to better understand its basic biology, while others aim to draw a causal link between LTP and behavioral learning. Still, others try to develop methods, pharmacologic or otherwise, of enhanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lipid Transfer Proteins
Plant lipid transfer proteins, also known as plant LTPs or PLTPs, are a group of highly- conserved proteins of about 7-9kDa found in higher plant tissues. As its name implies, lipid transfer proteins facilitate the shuttling of phospholipids and other fatty acid groups between cell membranes. LTPs are divided into two structurally related subfamilies according to their molecular masses: LTP1s (9 kDa) and LTP2s (7 kDa). Various LTPs bind a wide range of ligands, including fatty acids with a C10–C18 chain length, acyl derivatives of coenzyme A, phospho- and galactolipids, prostaglandin B2, sterols, molecules of organic solvents, and some drugs. The LTP domain is also found in seed storage proteins (including 2S albumin, gliadin, and glutelin) and bifunctional trypsin/ alpha-amylase inhibitors. These proteins share the same superhelical, disulfide-stabilised four-helix bundle containing an internal cavity. There is no sequence similarity between animal and plant LTPs. In animals, ...

Licklider Transmission Protocol
Licklider Transmission Protocol is a point to point protocol for use in deep space links. LTP is commonly seen as the standard underlying convergence layer protocol for the Bundle ProtocolsRFC 5050, supporting a wide selection of networks. LTP is named in honor of American computer scientist Joseph Carl Robnett Licklider. Design LTP is designed to run directly over a data link layer (e.g. the Advanced Orbiting Systems (AOS) Space Data Link Protocol). It can also run on the User Datagram Protocol (UDP), e.g. if used in a sensor network, in a private network (where bandwidth contestation isn’t an issue), or for software debug purposes. Therefore, it does not address issues like routing or congestion control. It was originally designed to support “long-haul” transmission in an interplanetary network; its design is based on experiences with the CCSDS File Delivery Protocol (CFDP). Developed for space communication, its features are: * Reliable data transport for importa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
'The All-Species Living Tree' Project
The All-Species Living Tree' Project is a collaboration between various academic groups/institutes, such as ARB Project, ARB, SILVA rRNA database project, and List of Prokaryotic names with Standing in Nomenclature, LPSN, with the aim of assembling a database of 16S ribosomal RNA, 16S rRNA sequences of all validly published species of ''Bacteria'' and ''Archaea''. At one stage, 23S ribosomal RNA, 23S sequences were also collected, but this has since stopped. Currently there are over 10,950 species in the aligned dataset and several more are being added either as new species are discovered or species that are not represented in the database are sequenced. Initially the latter group consisted of 7% of species. Similar (and more recent) projects include the Genomic Encyclopedia of Bacteria and Archaea (GEBA), which focused on whole genome sequencing of bacteria and archaea. Tree The tree was created by maximum likelihood analysis without bootstrap: consequently accuracy is traded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Local Transport Plan
{{Unreferenced, date=April 2008 Local transport plans, divided into full local transport plans (LTP) and local implementation plans for transport (LIP) are an important part of transport planning in England. Strategic transport authorities (county councils, unitary authorities, passenger transport authorities and London Borough councils), are expected to prepare them as forward-looking plans covering a number of years (typically five years), and present them to the Department for Transport (DfT). Different arrangements apply to Scotland, Wales and Northern Ireland as transport is a devolved matter. LTPs must: * Outline the current baseline with regard to transport, accessibility and pollution * Set out challenging but achievable objectives * Set out the programme for achieving these objectives * Outline 'bids' for funding from the DfT Once an LTP is prepared it is submitted to the Secretary of State for Transport (England only); in London, the related LIP is submitted to the May ...

Panzer 38(t)
The 38(t), originally known as the ČKD LT vz. 38, was a tank designed during the 1930s, which saw extensive service during World War II. Developed in Czechoslovakia by ČKD, the type was adopted by Nazi Germany following the annexation of Czechoslovakia. With the German Army and other Axis forces, the type saw service in the invasions of Poland, France and the USSR. Production ended in 1942, when its main armament was deemed inadequate. In all, over 1,400 Pz. 38(t)s were manufactured. The chassis of the Pz. 38(t) continued to be produced for the Marder III (1942–1944) with some of its components used in the later Jagdpanzer 38 (1944–1945) tank destroyer and its derivative vehicles. The (t) stands for , the German word for Czech; the Czechoslovak military designation was LT vz. 38 (, Light Tank model 38). Manufacturer's designations included TNH series, TNHPS, LTP and LTH. The special vehicle () designation for the tank in Germany was Sd. Kfz. 140. Description ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Transient Phenomena
A transient lunar phenomenon (TLP) or lunar transient phenomenon (LTP) is a short-lived light, color or change in appearance on the surface of the Moon. The term was created by Patrick Moore in his co-authorship of NASA Technical Report R-277 ''Chronological Catalog of Reported Lunar Events'', published in 1968. Claims of short-lived lunar phenomena go back at least 1,000 years, with some having been observed independently by multiple witnesses or reputable scientists. Nevertheless, the majority of transient lunar phenomenon reports are irreproducible and do not possess adequate control experiments that could be used to distinguish among alternative hypotheses to explain their origins. Most lunar scientists will acknowledge transient events such as outgassing and impact cratering do occur over geologic time. The controversy lies in the frequency of such events. Description of events Reports of transient lunar phenomena range from foggy patches to permanent changes of the lunar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Local Tangent Plane
Local tangent plane coordinates (LTP), also known as local ellipsoidal system, local geodetic coordinate system, or local vertical, local horizontal coordinates (LVLH), are a spatial reference system based on the tangent plane defined by the local vertical direction and the Earth's axis of rotation. It consists of three coordinates: one represents the position along the northern axis, one along the local eastern axis, and one represents the vertical position. Two right-handed variants exist: east, north, up (ENU) coordinates and north, east, down (NED) coordinates. They serve for representing state vectors that are commonly used in aviation and marine cybernetics. Axes These frames are location dependent. For movements around the globe, like air or sea navigation, the frames are defined as tangent to the lines of geographical coordinates: *East-West tangent to parallels, *North-South tangent to meridians, and *Up-Down in the direction normal to the oblate spheroid used as Ear ...

Long Term Prediction
In GSM, a Regular Pulse Excitation-Long Term Prediction (RPE-LTP) scheme is employed in order to reduce the amount of data sent between the mobile station (MS) and base transceiver station (BTS). In essence, when a voltage level of a particular speech sample is quantified, the mobile station's internal logic predicts the voltage level for the next sample. When the next sample is quantified, the packet sent by the MS to the BTS contains only the error (the signed difference between the actual and predicted level of the sample). See also * GSM * Quantization (signal processing) Quantization, in mathematics and digital signal processing, is the process of mapping input values from a large set (often a continuous set) to output values in a (countable) smaller set, often with a finite number of elements.
