In this paper, we propose a human activity recognition method from first-person videos, which provides a supplementary method to improve the recognition accuracy. Conventional methods detect objects and derive a user's behavior based on their taxonomy. One of the recent works has achieved accuracy improvement by determining key objects based on hand(More)
This paper investigates substrate noise influence on circuit performance in a variable threshold-voltage scheme (VT scheme) where threshold voltage is dynamically varied by substrate-bias control to reduce active power dissipation. It is experimentally examined that substrate-bias can be controlled stably with very few substrate-contacts. Measured tracking(More)
Histochemical and morphological studies in culture were carried out on 4 cases from the normal human adrenal cortex (NHA), 1 case from CUSHING'S adenoma (CS), 4 cases from CONN'S adenoma (primary aldosteronism, PA) and 1 case from adrenocorti-cal carcinoma (ACC). Cultured cells from CS and ACC transformed rapidly into fibroblast-like cells, while those from(More)
Epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) are validated molecular targets in cancer therapy. Dual blockade has been explored and one such agent, lapatinib, is in clinical practice but with modest activity. Through chemical screening, we discovered a novel EGFR and HER2 inhibitor, S-222611, that selectively(More)
This paper proposes a hierarchical secret sharing method for image data. In the conventional secret sharing scheme (SSS), secret data is reconstructed only if more shares are gathered and combine than a pre-decided number, k. Though large k makes a strong security feature, it creates problems with the handling of the many shares required to reconstruct the(More)
