BACKGROUND Semiquantitative evaluation and manual cell counting are the commonly used procedures to assess positive staining of molecular markers in tissue sections. Manual counting is also a laborious task in which consistent objectivity is difficult to achieve. Recently, image analysis has been explored, but the studies reported were limited to histological images acquired at high magnificati...

We recently proposed Counter Braids, an SRAM-only counter architecture for high-speed per-flow counting. Accurate per-flow counting was deemed complex and expensive because of the need for large arrays of counters operating at very high link speed (e.g. 40 Gbps). A naive algorithm needs an infeasible amount of SRAM to store both the counters and a flow-to-counter association rule, so that arriv...

The tremendous growth in the field of modern communication and network systems places demands on the security. As the network complexity grows, the need for the automated detection and timely alert is required to detect the abnormal activities in the network. To diagnose the system against the malicious signatures, a high speed Network Intrusion Detection System is required against the attacks....

This paper describes the preliminary results of an efficient language classifier using an ad-hoc Cumulative Frequency Addition of N-grams. The new classification technique is simpler than the conventional Naïve Bayesian classification method, but it performs similarly in speed overall and better in accuracy on short input strings. The classifier is also 5-10 times faster than N-gram based rank-...

Charged particles traveling through a conventional medium at a speed greater than the speed of light in the medium produce Cherenkov radiation in the forward directions, which is useful for particle identification and counting. Newly designed metamaterial, with their negative index of refraction, flips the radiated photons backward and thus readily separates the radiation from the emitting part...

Memory retrieval requires both accuracy and speed. Olfactory learning of the fruit fly Drosophila melanogaster serves as a powerful model system to identify molecular and neuronal substrates of memory and memory-guided behavior. The behavioral expression of olfactory memory has traditionally been tested as a conditioned odor response in a simple T-maze, which measures the result, but not the sp...

BACKGROUND Tumor proliferation speed, most commonly assessed by counting of mitotic figures in histological slide preparations, is an important biomarker for breast cancer. Although mitosis counting is routinely performed by pathologists, it is a tedious and subjective task with poor reproducibility, particularly among non-experts. Inter- and intraobserver reproducibility of mitosis counting ca...

We propose and experimentally demonstrate a high-efficiency single-pixel imaging (SPI) scheme by integrating time-correlated single-photon counting (TCSPC) with time-division multiplexing to acquire full-color images at an extremely low light level. This SPI uses digital micromirror device modulate sequence of laser pulses preset delays achieve three-color structured illumination, then employs ...
