We develop and apply two new methods for analyzing file system behavior and evaluating file system changes. First, semantic block-level analysis (SBA) combines knowledge of on-disk data structures with a trace of disk traffic to infer file system behavior; in contrast to standard benchmarking approaches, SBA enables users to understand why the file system behaves as it does. Second, semantic tr...
Alzheimer's disease (AD) is characterized pathologically by the abundance of senile plaques and neurofibrillary tangles in the brain. We synthesized over 1200 novel gamma-secretase modulator (GSM) compounds that reduced Abeta(42) levels without inhibiting epsilon-site cleavage of APP and Notch, the generation of the APP and Notch intracellular domains, respectively. These compounds also reduced...
We present a wide field, sub-arcminute resolution VLA image of the Galactic Center region at 330 MHz. With a resolution of ∼ 7 × 12 and an RMS noise of 1.6 mJy beam, this image represents a significant increase in resolution and sensitivity over the previously published VLA image at this frequency. The improved sensitivity has more than tripled the census of small diameter sources in the region...
Brain reserve refers to the ability of the brain to tolerate pathological changes such as those seen in AD before manifesting clinical signs and symptoms [1-3]. Neurotrophic factors (NTFs), most notably Brain Derived Neurotrophic Factor (BDNF) and its receptor Tyrosine kinase B (TrkB), regulate synaptic plasticity and functional efficiency in adulthood [4-6] and thus may influence brain reserve...
With the virtual machine technologies, Virtual Ad hoc Network (VAN) testbed was designed to evaluate functional correctness and communication performance of Mobile Ad hoc Network (MANET) applications. When VAN is used for large-scale testing that requires hundreds of virtual machines, storage redundancy becomes an issue. Although Content Addressable Storage (CAS) techniques were designed to add...
A design flow for ΔΣ modulators is illustrated, allowing quantization noise to be shaped according to an arbitrary weighting profile. Being based on FIR NTFs, possibly with high order, the flow is best suited for digital architectures. The work builds on a recent proposal where the modulator is matched to the reconstruction filter, showing that this type of optimization can benefit a wide range...
In vertebrates the development and function of the nervous system is regulated by neurotrophic factors (NTFs). Despite extensive searches no neurotrophic factors have been found in invertebrates. However, cell ablation studies in Drosophila suggest trophic interaction between neurons and glia. Here we report the invertebrate neurotrophic factor in Drosophila, DmMANF, homologous to mammalian MAN...
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by cognitive impairment and multiple pathological lesions. At the molecular level, AD is characterized by overt amyloid β (Aβ) production and tau hyper-phosphorylation. Hence, pharmacological agents that can attenuate Aβ accumulation and tau hyper-phosphorylation have potential promise for treatment of AD. Rapamycin, an inhi...
We propose and explore the applicability of file timestamps as a steganographic channel. We identify an information gap between storage and usage of timestamps in modern operating systems that use high-precision timers. Building on this, we describe a layered design of a steganographic system that offers stealthiness, robustness, and wide applicability. The proposed design is evaluated through ...
