Gravity models are widely used to explain patterns of trade. However, two stylized features of trade data, sample selection and heteroskedasticity, challenge the estimation of gravity models. We propose a Two-Step Method of Moments (TS-MM) estimator that deals with both issues. The Monte-Carlo experiments show that the TS-MM estimates are resistant to various combinations of sample selection an...

Weare developing a 1 mm resolution breastdedicated Positron Emission Tomography (PET) system in an effort to increase the role of PET in earlier stages of breast cancer management. The system consists of two 16 cm x 9 cm x 2 cm detector panels constructed using stacked layers of 8x8 arrays of 1 mm LSO scintillation crystals coupled to Position Sensitive Avalanche Photodiodes (PSAPDs). Prelimina...

Number of Papers published in peer-reviewed journals: Number of Papers published in non peer-reviewed journals: Final Report: Information Dynamics in Networks: Models and Algorithms Report Title In this project, we investigated how network structure interplays with higher level processes in online social networks. We investigated the appropriateness of existing mathematical models for explainin...

ML-PMHT Track Detection Threshold Determination for K-Distributed Clutter Report Title Recentwork developed a novelmethod for determining tracking thresholds for theMaximumLikelihood ProbabilisticMultiHypothesis Tracker (ML-PMHT). Under certain “ideal” conditions, probability density functions (PDFs) for the peak points in the ML-PMHT log-likelihood ratio (LLR) due to just clutter measurements ...

Undersampling and pixelation affect a number of imaging systems, limiting the resolution of the acquired images, which becomes particularly significant for wide-field microscopy applications. Various superresolution techniques have been implemented to mitigate this resolution loss by utilizing sub-pixel displacements in the imaging system, achieved, for example, by shifting the illumination sou...

Advancements in semiconductor technology have led to a steady increase in the unity power gain frequency (fmax) of silicon transistors, both in CMOS and SiGe BiCMOS technologies. This, in turn, enables realization of complex monolithic silicon integrated circuits operating at the millimeter-wave (mm-wave) frequency range (typically defined as 30–300 GHz). Prime target applications of silicon mm...

We have reported that a novel c-Myc-binding protein, MM-1, repressed E-box-dependent transcription and transforming activities of c-Myc and that a mutation of A157R in MM-1, which is often observed in patients with leukemia or lymphoma, abrogated all of the repressive activities of MM-1 toward c-Myc, indicating that MM-1 is a novel tumor suppressor. MM-1 also binds to the ubiquitin-proteasome s...

Drug susceptibility of matrix-encapsulated Report Title The rise in the use of biomedical devices and implants has seen a concomitant surge in the advent of device-related nosocomial (hospital-acquired) infections of bacterial and fungal origins. The most common nosocomial fungal infection is candidiasis caused mainly by Candida albicans biofilms. Candidiasis is associated with an unacceptably ...
