This review gives an overview of our recent findings and developments in research on brain mechanisms of morphine reward from studies using the place preference conditioning paradigm. Intracranial place conditioning methodology has become a valuable and firmly established and very widely used tool in behavioural pharmacology and drug reward mechanisms.

Identification functions of 20 initial and 20 final consonants were characterized in 9600 randomly sampled consonant-vowel-consonant (CVC) tokens presented in speech-spectrum noise. Because of differences in the response criteria for different consonants, signal detection measures were used to quantify identifiability. Consonant-specific baseline signal-to-noise ratios (SNRs) were adjusted to p...

Nonlinear system identification is a vast research field, today attracting a great deal of attention in the structural dynamics community. Ten years ago, an MSSP paper reviewing the progress achieved until then [1] concluded that the identification of simple continuous structures with localised nonlinearities was within reach. The past decade witnessed a shift in emphasis, accommodating the gro...

A family of lightweight authentication protocols, HB-family, has been proposed for low-computationload-required applications such as radio frequency identification (RFID). Security of this family is based on the learning parity with noise (LPN) problem which has been proven to be an NP-complete problem. But, we find that security of these LPN-problem-based protocols is doubted. We will demonstr...

We describe our system at the ImageCLEF 2013 plant identification task. Plant identification is extremely challenging because target classes are often visually quite similar. To distinguish them, we need to extract highly informative visual features. We believe that the key to achieving this is to enhance the discriminative power of local descriptors. We employed multiple local features with ou...

A state-of-the-art seismic monitoring system comprising 36 accelerometers and a data-logger with real-time capability was recently installed at Building 54 on the Massachusetts Institute of Technology’s (MIT) Cambridge, MA, campus. The system is designed to record translational, torsional, and rocking motions, and to facilitate the computation of drift between select pairs of floors. The cast-i...

During pauses in exploration, ensembles of place cells in the rat hippocampus re-express firing sequences corresponding to recent spatial experience. Such "replay" co-occurs with ripple events: short-lasting (approximately 50-120 ms), high-frequency (approximately 200 Hz) oscillations that are associated with increased hippocampal-cortical communication. In previous studies, rats exploring smal...

This paper presents a novel intellectual-property (IP) identification scheme using the existing System-on-a-Chip (SOC) watermarking design. An efficient and novel principle is established for IP identification which depends on the current IP design flow. The principle is embedding different Advanced Encryption Standard (AES) encoders in to System-on-a-Chip (SOC) based watermarked devices at beh...
