High-luminosity ee storage rings designed for the study of CP violation, such as KEK-B, PEP-B, and DAΦNE, have opened a new possibility to measure ee annihilation using initialstate radiation (ISR) [1,2,3]. A large mass range becomes accessible in a single experiment, especially at B factories, contrary to the case with fixed energy machines which are optimized only in a limited region. The bro...

Populations living at high altitudes (HAs), particularly in the Peruvian Andes, are characterized by a mixture of subjects with erythrocytosis (16 g dl(-1)21 g dl(-1)). Elevated haemoglobin values (EE) are associated with chronic mountain sickness, a condition reflecting the lack of adaptation to HA. According to c...

In this paper, the energy efficiency (EE) of downlink distributed antenna system (DAS) with multiple receive antennas is investigated over composite fading channel that takes the path loss, shadow fading and Nakagami-m fading into account. Our aim is to maximize EE which is defined as the ratio of the transmission rate to the total consumed power under the constraints of maximum transmit power ...

Algorithms for joint subcarrier pairing and power allocation are investigated in order to maximize the worst-case energy efficiency (EE) in dual-hop decode-and-forward (DF) relay networks in the presence of an active eavesdropper. Accordingly, we study the impact of number of subcarriers on the trade-off in performance between the EE and the spectrum efficiency (SE). The formulated EE optimizat...

We report the first measurement of the absolute branching fraction ee → BB at the Υ (4S) resonance using data collected with the BABAR detector at the PEP-II asymmetric-energy ee storage ring. The analysis is performed with partial reconstruction of the decay B → Dlν̄l, where the presence of a signal decay is determined using only the lepton and the soft pion from the D∗ decay. By reconstructing...

Carbon dioxide production, water production, and energy expenditure (EE) determined with 2H2(18)O were validated using a room calorimeter. Nine human subjects (5 males, 4 females) resided in the calorimeter for five to seven consecutive 23.5-h days. Daily carbon dioxide and water production and EE were averaged from calorimeter data and compared with 2H2(18)O results for the same period and for...

Massive multi-input multi-output (MIMO) can support high spectral efficiency (SE) with simple linear transceivers, and is expected to provide high energy efficiency (EE). In this paper, we analyze the EE of downlink multi-cell massive MIMO systems under spatially correlated channel model, where both transmit and circuit power consumptions, training overhead, channel estimation and pilot contami...

This study investigates wireless information and energy transfer for dual-hop amplify-and-forward full-duplex relaying systems. By forming energy efficiency (EE) maximization problem into a concave fractional program of transmission power, three relay control schemes are separately designed to enable energy harvesting and full-duplex information relaying. With Rician fading modeled residual sel...

OBJECTIVES To determine the association between objectively measured physical activity (PA), fractures, and falls. DESIGN Longitudinal cohort study. SETTING Six U.S. clinical sites. PARTICIPANTS Two thousand seven hundred thirty-one men with a mean age of 79. MEASUREMENTS Total and active energy expenditure (EE) and minutes per day spent in sedentary and moderate intensity activities we...

BACKGROUND AND AIM: Ectopic eruption (EE) of the permanent first molars (PFMs) results from a discrepancy between the jaw growth rate and the growth rate of these teeth. The present study was undertaken to evaluate the prevalence of EE of PFMs in Kerman, Iran, and then determine the relationship between growth parameters (height and weight) and this developmental anomaly.METHODS: In the present...
