Locked, Unlocked and Semi-locked Network Weights for Four Different Camera Calibration Problems

Backpropagation training algorithms typically view network weights as a single vector of isotropic parameters to be minimized. In contrast, we present a neural network in which each network weight has its own physical meaning and its di erent role during network training. The network is used to solve four di erent types of calibration problems found in computer vision applications. A network we...

Uterine closure with unlocked suture in cesarean section: Safety and Quality

OBJECTIVE Comparing locked and unlocked uterine closure techniques in terms of bleeding control and uterine incision healing. METHODS The patients undergoing cesarean section in Sifa University Hospital between May - October 2012 were accepted to this prospective controlled study. Primarily, safety was evaluated. The hemoglobin count (HC) and serum creatine kinase (CK) levels of the patients ...

Revealing Time-Unlocked Brain Activity from MEG Measurements by Common Waveform Estimation

Brain activities related to cognitive functions, such as attention, occur with unknown and variable delays after stimulus onsets. Recently, we proposed a method (Common Waveform Estimation, CWE) that could extract such brain activities from magnetoencephalography (MEG) or electroencephalography (EEG) measurements. CWE estimates spatiotemporal MEG/EEG patterns occurring with unknown and variable...

Rural population survey of behavioral and demographic risk factors for loaded firearms.

OBJECTIVES In the United States, firearm deaths are almost as frequent as motor vehicle deaths. Firearm unintentional and suicide death rates are raised in rural areas. This study examines firearm prevalence and storage practices in three different types of rural households. METHODS Adults from a stratified random sample of 983 households in a rural Iowa county were interviewed. The chi2 test...
