This paper proposes an efficient array beam-forming method using spatial matched filtering (SMF) for ultrasonic imaging. In the proposed method, ultrasonic waves are transmitted from an array subaperture with fixed transmit focus as in conventional array imaging. At receive, radio frequency echo signals from each receive channel are passed through a spatial matched filter that is constructed ba...

BACKGROUND The purpose of this study was to clarify the value of renal drainage half-time in the evaluation of pediatric hydronephrosis after dismembered pyeloplasty. METHODS We reviewed the records of 30 children who underwent dismembered pyeloplasty for unilateral ureteropelvic junction obstruction with no other associated urological abnormality. The follow-up duration was more than 5 years...

Abstract Introduction Theoretically, during dreaming, weak associations are explored, and information is combined in novel ways, which could lead to increased creativity waking. However, little research has explored direct relationships between dreaming objective measures of the ability creatively solve problems. Furthermore, personality influences dream recall frequency (DRF) other aspects sug...

[1] The Arctic is warming two to four times faster than the global average. Debate continues on the relative roles of local factors, such as sea ice reductions, versus remote factors in driving, or amplifying, Arctic warming. This study examines the vertical profile and seasonality of observed tropospheric warming, and addresses its causes using atmospheric general circulation model simulations...

INTRODUCTION Distal radius fracture (DRF) accompanied by intra-articular volar displaced fragment is difficult to reduce. This volar fragment remains when treated with a simple buttress effect alone, and V-shaped deformity may remain on the articular surface. We attempted to improve dorsal rotational deviation of volar fragment by osteosynthesis applying the condylar stabilizing technique. We r...

We present new characterizations of the Raiffa and Kalai-Smorodinsky solutions based on strategyproofness of an allocation mechanism for an underlying economy with Leontief preferences. Our first result shows that the 2-player Kalai-Smorodinsky solution is the unique bargaining solution which if Efficient, Symmetric, Scale Invariant and Strategyproof on a Leontief economy. Next we consider the ...

The aim of the present study was to assess recovery from hematopoietic and gastrointestinal damage by Ex-RAD(®), also known as ON01210.Na (4-carboxystyryl-4-chlorobenzylsulfone, sodium salt), after total body radiation. In our previous study, we reported that Ex-RAD, a small-molecule radioprotectant, enhances survival of mice exposed to gamma radiation, and prevents radiation-induced apoptosis ...

OBJECTIVE To assess the availability of essential drugs and the perceptions of clients on drugs situation in the primary health centres of Tafa Local Government Area, north central Nigeria. METHODS Checklist consisting of minimum drugs expected in a generic primary health centre developed by the National Primary Health Care Development Agency (NPHCDA) was adopted and used to assess drugs avai...

We investigate the performance of two discrete solvent models in connection with density functional theory (DFT) for the calculation of molecular properties. In our comparison we include the discrete reaction field (DRF) model, a combined quantum mechanics and molecular mechanics (QM/MM) model using a polarizable force field, and the frozen-density embedding (FDE) scheme. We employ these solven...

Basil (Ocimum basilicum) was cultivated in Rostock, Northern Germany, a decoupled aquaponic system with African catfish (Clarias gariepinus) under intensive rearing conditions by using three hydroponic components, the dynamic root floating technique (DRF), raft technique, and grow pipes. A 25% of recommended feed input still allowed growth provided adequate nitrogen calcium levels process water...
