A system and method for processing information in a data set that contains samples of at least two classes using an empirical risk minimization model, wherein each sample in the data set has an importance score. In one embodiment, the method includes the step of selecting samples of a first class being labeled with class label +1 and a second class with class label −1, from the data set, prescribing an empirical risk minimization model using the selected samples with an objective function and a plurality of constraints which adequately describes the solution of a classifier to separate the selected samples into the first class and the second class, modifying the empirical risk minimization model to include terms that individually limit the influence of each sample relative to its importance score in the solution of the empirical risk minimization model, and solving the modified empirical risk minimization model to obtain the corresponding classifier to separate the samples into the first class and the second class.

An imaging system includes an RF source, a focal plane array and device for focusing the RF signal from the RF source. The focal plane array includes a plurality of carbon nanotube mixers for capturing RF signals and down-converting the signals to a selected bandwidth and output an output signal. The device focuses the RF signal output from said RF source onto the focal plane array.

The emergence of multidrug-resistant pathogens necessitates the search for new antibiotics acting on previously unexplored targets. Nicotinate mononucleotide adenylyltransferase of the NadD family, an essential enzyme of NAD biosynthesis in most bacteria, was selected as a target for structure-based inhibitor development. To this end, the inventors have identified small molecule compounds that inhibit bacterial target enzymes by interacting with a novel inhibitory binding site on the enzyme while having no effect on functionally equivalent human enzymes.

A replacement buttstock includes a stock body and a locking lever assembly. The stock body has an elongated receiving chamber for receiving a connecting extension of a rifle. The locking lever assembly includes a lever element, a locking pin, a stopper element and a restoring element. The stopper element is operated to allow the lever element to move to an unlock state in which the locking pin is driven to move out of the receiving chamber for unlocking the connecting extension, so that the buttstock is convenient and easy to be quickly assembled with and detached from the rifle while the user does not have to change his or her original aiming gesture.
