Tuberous Sclerosis Complex
Tuberous sclerosis complex (TSC) is a rare multisystem autosomal dominant genetic disease that causes non-cancerous tumours to grow in the brain and on other vital organs such as the kidneys, heart, liver, eyes, lungs and skin. A combination of symptoms may include seizures, intellectual disability, developmental delay, behavioral problems, skin abnormalities, lung disease, and kidney disease. TSC is caused by a mutation of either of two genes, ''TSC1'' and ''TSC2'', which code for the proteins hamartin and tuberin, respectively, with ''TSC2'' mutations accounting for the majority and tending to cause more severe symptoms. These proteins act as tumor growth suppressors, agents that regulate cell proliferation and differentiation. Prognosis is highly variable and depends on the symptoms, but life expectancy is normal for many. The prevalence of the disease is estimated to be 7 to 12 in 100,000. The disease is often abbreviated to tuberous sclerosis, which refers to the ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuberous Sclerosis Protein
Tuberous sclerosis proteins 1 and 2, also known as TSC1 (hamartin) and TSC2 (tuberin), form a protein-complex. The encoding two genes are ''TSC1'' and ''TSC2''. The complex is known as a tumor suppressor. Mutations in these genes can cause tuberous sclerosis complex. Depending on the grade of the disease, intellectual disability, epilepsy and tumors of the skin, retina, heart, kidney and the central nervous system can be symptoms. Physiological roles The TSC1/TSC2-complex integrates environmental signals such as stress and energy status in yeast and stress, energy status and growth factors in mammals into TOR signalling. In the case of stress (DNA damage, hypoxia) or low energy availability, it is activated and regulates protein synthesis down. Growth factors lead to an inhibition of the complex and have a positive effect on protein synthesis. Defects in its genes result in less control of cell growth and may cause tuberous sclerosis or tuberous sclerosis complex (TSC). TSC i ...

Thyristor Switched Capacitor
A thyristor-switched capacitor (TSC) is a type of equipment used for compensating reactive power in electrical power systems. It consists of a power capacitor connected in series with a bidirectional thyristor valve and, usually, a current limiting reactor (inductor). The thyristor switched capacitor is an important component of a Static VAR Compensator (SVC),Hingorani, N.G. & Gyugyi, L. Understanding FACTS - Concepts and Technology of Flexible AC Transmission Systems. IEEE. . where it is often used in conjunction with a thyristor controlled reactor (TCR). Static VAR compensators are a member of the Flexible AC transmission system (FACTS) family. Circuit diagram A TSC is usually a three-phase assembly, connected either in a delta or a star arrangement. Unlike the TCR, a TSC generates no harmonics and so requires no filtering. For this reason, some SVCs have been built with only TSCs .[Horwill, C., Young, D.J., Wong, K.T.G.

Time Stamp Counter
The Time Stamp Counter (TSC) is a 64-bit register present on all x86 processors since the Pentium. It counts the number of CPU cycles since its reset. The instruction RDTSC returns the TSC in EDX:EAX. In x86-64 mode, RDTSC also clears the upper 32 bits of RAX and RDX. Its opcode is 0F 31. Pentium competitors such as the Cyrix 6x86 did not always have a TSC and may consider RDTSC an illegal instruction. Cyrix included a Time Stamp Counter in their MII. Use The Time Stamp Counter was once an excellent high-resolution, low-overhead way for a program to get CPU timing information. With the advent of multi-core/ hyper-threaded CPUs, systems with multiple CPUs, and hibernating operating systems, the TSC cannot be relied upon to provide accurate results — unless great care is taken to correct the possible flaws: rate of tick and whether all cores (processors) have identical values in their time-keeping registers. There is no promise that the timestamp counters of multiple CPUs on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Time To Succeed Coalition
The Time to Succeed Coalition (TSC) is a U.S. based non-profit organization working to build a coalition in support of expanded learning time (ELT) for students in communities of concentrated poverty. Background TSC is co-chaired by Chris Gabrieli, Chairman of the National Center on Time & Learning, and Luis Ubiñas, President of the Ford Foundation. Expanded learning time is an issue that has long been on the education agenda in the United States. As more schools across the country began exploring how to expand their school schedules following new federal investments and research noting the impact of longer school years on student achievement became available, the coalition was formed. TSC launched on May 10, 2012 with a mission: to inspire and motivate communities across the country to add more learning time to a redesigned school day and year, enabling children everywhere – especially in disadvantaged schools – to get the education they need to succeed.
