摘要： A learning system for a search ranking function model may include a computer program that iteratively refines the model using new queries and associated documents from an unlabeled training set. The unlabeled training set may include a set of queries for which the associated documents have not been labeled as “relevant” or otherwise labeled. The new queries may be selected based on a similarity to and an accuracy of each neighbor from a labeled training set, such as a labeled validation set. Upon selection, the documents associated with the new queries may be labeled. The new queries and their associated documents may be accumulated into a labeled training set, such as a labeled training set, and a refined model may be learned based on the augmented labeled training set. The model may be iteratively refined until it is determined that the model is adequate.

摘要： The invention relates to treatment of neurodegenerative diseases with JAK/STAT pathway inhibitors to eliminate extracellular cell signaling events leading to cell cycle abrogation and/or apoptosis. Primary neurons were administered neurotoxic proteins, such as gp120, Tat, or gp120 and Tat, with or without IFN-γ added, resulting in neuronal death, and simulated neurodegenerative diseases. The neurodegenerative disease is treated using a JAK/STAT pathway inhibitor, including (-)-epigallocatechin-3-gallate (EGCG), to modulate JAK1 or STAT1 phosphorylation, resulting in resistance to gp120 or Tat neurotoxicity. The invention may be used to treat neurons afflicted with HIV-associated Dementia, multiple sclerosis, Alzheimer's Disease, Parkinson's Disease, amyotrophic lateral sclerosis, or Pick's Disease, and may act in conjunction with antiviral treatment, like HAART.

摘要： The Rabi frequency of oscillation of the nuclear magnetization vector of a sample in an NMR system may be controlled by modifying only the duty cycle of RF pulses delivered to the sample, without modifying the amplitude of the RF pulses, until the energy delivered at the Larmor frequency is adjusted to a desired amount. An impedance matching network between an NMR transceiver and an NMR coil may perform both power matching and noise matching simultaneously. During a transmission mode, the impedance matching network is connected to a transmitter portion of the transceiver, and the impedance of the coil is matched to the driver resistance. During a receiver mode, the impedance matching network is disconnected from the transmitter portion so that the impedance matching network remains connected only to the receiver portion, and signal-to-noise ratio in received NMR signals is maximized.
摘要翻译： NMR系统中样品的核磁化矢量的Rabi振荡频率可以通过仅修改传送到样品的RF脉冲的占空比而不修改RF脉冲的幅度来控制，直到在Larmor处传送的能量频率被调整到期望的量。 NMR收发器和NMR线圈之间的阻抗匹配网络可以同时执行功率匹配和噪声匹配。在传输模式期间，阻抗匹配网络连接到收发器的发射器部分，并且线圈的阻抗与驱动器电阻相匹配。在接收器模式期间，阻抗匹配网络与发射机部分断开，使得阻抗匹配网络仅保持连接到接收机部分，并且接收的NMR信号中的信噪比最大化。

摘要： Digital background calibration in a pipelined ADC is performed by extracting a capacitor mismatch value Δ that represents a mismatch between a sampling capacitor C1 and a feedback capacitor C2 in the pipelined ADC, and using Δ to correct the capacitor mismatch error. Δ is extracted by performing commutated feedback capacitor switching (CFCS) in a background correlation loop. The error caused by the capacitor mismatch is calibrated out by subtracting the error from a digital output Dout of the pipelined ADC. Convergence speed may be accelerated and convergence accuracy may be increased during digital background calibration of pipelined ADCs, by using a higher order LPF. A bandwidth switching scheme may be implemented by the LPF, i.e. a larger bandwidth may be utilized during calibration start-up to increase convergence speed during start-up and a smaller bandwidth may be utilized during steady state to increase convergence accuracy during steady state.
