The experimental PNC results in 18F, 19F, 21Ne and the current theoretical analysis show a discrepancy . If one interprets the small limit of the experimentally extracted PNC matrix element for 21Ne as a destructive interference between the isoscalar and the isovector contribution, then it is difficult to understand why the isovector contribution in 18F is so small while the isoscalar + isovect...

I. ABSTRACT We present a Gallium Nitride (GaN) Lamb Wave resonator using a Phononic Crystal (PnC) to selectively confine elastic vibrations with wide-band spurious mode suppression. A unique feature of the design demonstrated here is a folded PnC structure to relax energy confinement in the non-resonant dimension and to enable routing access of piezoelectric transducers inside the resonant cavi...

Network coding, where relay nodes combine the information received from multiple links rather than simply replicating and forwarding the received packets, has shown the promise of significantly improving system performance. In very recent works, multiple researchers have presented methods for increasing system throughput by employing network coding inspired methods to mix packets at the physica...

OBJECTIVE To examine the effect of prenatal care (PNC) on the level and distribution of child stunting in three Andean countries-Bolivia, Colombia, and Peru-where expanding access to such care has been an explicit policy intervention to tackle child malnutrition in utero and during early childhood. METHODS An econometric analysis of cross-sectional Demographic and Health Survey (DHS) data was...

Studies of transmutation of long-lived fission products by accelerator and by fission reactor at PNC are described. Four transmutation methods by accelerators are compared in terms of transmutation energy and transmutation rate. A super-powered electron linear accelerator which could transmute a large quantity of fission products has been studied and development of PNC test linac in this line i...

In wireless networks, the bandwidth is considered one of the most scarce and valuable resources. The physical layer network coding (PNC) technique encourages strategically picked senders to interfere so that the destination nodes can leverage the network level information to recover the signals. PNC can yield higher capacity than network layer network coding when applied to wireless networks. H...

We report on a determination of the parity nonconserving (PNC) matrix element in the bound parity doublet f--y’ of “‘Tc. The experiment was carried out at the GSI, Darmstadt and LNL, Legnaro laboratories. The recoil-mass-separated radioactive beam of ‘“Tc nuclei in the yisomer, following a fusion-evaporation reaction, was polarized by the tilted-foil method and the resulting O”-180” y asymmetry...

This document describes the hierarchical agglomerative cluster algorithm Pnc 2 in the context of direct generation of If-Then rules for classification tasks. As an agglomerative cluster algorithm, the Pnc 2 initializes each learn data tuple as a single cluster. Then, if a merge test is passed, iteratively always those two clusters with the same output value are merged, that are closest to each ...

BACKGROUND AND AIMS Both nutrient availability and defoliation affect the carbon-nutrient balance in plants, which in turn influences biomass allocation (e.g. shoot-to-root ratio) and leaf chemical composition (concentration of nitrogen and secondary compounds). In this study it is questioned whether defoliation alters biomass allocation and chemical defence in a similar fashion to the response...
