Accurate BER Analysis of QPSK Modulated Asynchronous DS-CDMA Systems Communicating over Rayleigh Channels

, 2006
The accurate average BER calculation of an asynchronous DS-CDMA system using random spreading sequences is studied in Rayleigh fading channels. An accurate closed-form expression is derived for the conditional characteristic function of the multiple ...

Missed opportunities to prevent HIV acquisition with pre‐exposure prophylaxis: A mixed methods study of people with recently acquired HIV in the United Kingdom

HIV Medicine, EarlyView.
Abstract Objectives To explore missed opportunities for PrEP use among people with recently acquired HIV in the United Kingdom. Methods Data were derived from CASCADE, an international, longitudinal, mixed‐methods study of adults (≥16 years) with recently acquired HIV (≤12 months).

The Random Power Function for Tests Based on Pivotal Quantities

International Statistical Review, EarlyView.
Summary In clinical trials planning, evaluation of the probability of success of an experiment is of central interest, for instance, in sample size determination. This assessment typically involves analyses of the power function of a test on a parameter of interest, such as a relevant treatment effect.

Insights into the morphometric and molecular characterisation of ber fruit fly (Carpomyia vesuviana Costa) infesting jujube ber, Ziziphus mauritiana (Lamk.)

Plant Protection Science
Carpomyia vesuviana Costa, a fruit fly species, is a major pest affecting the jujube (Ber). This monophagous insect pest causes significant economic losses in regions where the jujube is cultivated.

Co‐Design at the Boundary: Understanding the Dynamics of Open Innovation Between Companies and Communities

Journal of Product Innovation Management, EarlyView.
ABSTRACT For over two decades, firms have built platforms and engaged open innovation communities to improve and customize their products through widened participation in the design process. While the benefits of involving those outside a firm as co‐designers have been well described, how co‐design processes unfold over time at the boundary between ...

Acquisitive root exploration strategies help maintain higher peak sap flux rates during summer drought, but more root biomass does not

New Phytologist, EarlyView.
Summary Roots are responsible for soil water uptake, yet little is known about how variation in fine‐root traits relates to whole‐tree water movement, particularly during periods of drought. By combining a 3‐yr dataset monitoring sap flow rates with measures of fine‐root biomass, length, and morphology across 10 tree species, we addressed hypotheses ...

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

New Phytologist, EarlyView.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

PPT1‐mediated plastidic phosphoenolpyruvate import enhances fatty acid biosynthesis in sugar‐rich tissues

New Phytologist, EarlyView.
Summary Metabolic engineering of vegetative tissues for lipid production holds transformative potential for sustainable biofuels, yet achieving sufficient yields remains challenging. Here, we present a strategy to enhance fatty acid synthesis by redirecting cytosolic phosphoenolpyruvate (PEP) into plastids through overexpression of the plastidial ...
