SLC/SLD provides the ideal experimental environment to directly measure the parity violation parameters at the Zbb, Zcc vertex decays. Three di erent analysis techniques exploit the multi-purpose detector capabilities and are brie y described; the updated result obtained with the semileptonic decay method is presented. Presented at the 28th International Conference on High Energy Physics Warsaw...

The strong coupling a, has been measured using hadronic decays of 2° bosons co~ected by the SLD experiment at SLAC. The data were compared with QCD predictions both at fixed order, O(a~ ), and including resummed analytic formulae based on the leading and next-toleading logarithm approximation. We studied event shapes, jet rates, particle correlations, and energy fraction and checked the consist...

The present paper supplements recent contributions to the systematics of derelomine flower weevils from the Neotropics (Franz 2001, Franz & O’Brien 2001a, 2001b). Under the current conception, Derelomini (Coleoptera: Curculionidae: Curculioninae sensu Alonso-Zarazaga & Lyal 1999) comprise 220 species and 39 genera, the majority of which are associated with the inflorescences of Arecaceae. Some ...

We have measured the di erential cross sections for the production of , K, K, K , , p, and their corresponding antiparticles in separate samples of avor-tagged Z ! lightavor (u u, d d, or s s), Z ! c c and Z ! b b events. Clear avor dependences are observed, and the results are compared with the predictions of three fragmentation models. We have also performed a direct measurement of As, the pa...

Physostigmine (Phy) was determined in plasma and cerebrospinal fluid (CSF) by HPLC with electrochemical detection, with use of a normal-phasecolumn and methanolic sodium acetate buffer, pH 4.6. The detection limit of the method was 0.5 ig/L for a 2-mL sample of plasma or 0.5 mL of CSF. Analytical recovery of Phy in the range from 0.5 to 40 ,ug/L was 60% (SD 5%) for plasma and 78% (SD 8%) for CS...

The main target of this article is to propose a simple Received Signal Strength Indicator- (RSSI-) based adaptive Physical Layer (PHY) selection approach for Bluetooth Low Energy 5.0 (BLE 5) and compare the performance PHY with individual PHY. This also validates simulation results acquired from in-house developed Ray Tracing (RT) tool BLE 5 measurements conducted in corridor TUAS building, Aal...

This proposal is a first pass at adding what is required in 08-015r3 for the phy and link layer state diagrams to include the low power transceiver options of partial and slumber modes for SAS. 1) The following are the proposed changes to the SP state machine. 6.8.1 SP state machine overview The SP state machine controls the phy reset sequence. This state machine consists of three four sets of ...

Intelligent reflecting surface (IRS) has emerged as an appealing solution to enhance wireless communication performance by reconfiguring the propagation environment. In this paper, we propose apply IRS physical-layer service integration (PHY-SI) system, where a single-antenna access point (AP) integrates two sorts of messages, i.e., multicast message and confidential message, via superposition ...

The collagen prolyl 4-hydroxylases (collagen P4Hs, EC 1.14.11.2) play a key role in the synthesis of the extracellular matrix. The vertebrate enzymes are alpha(2)beta(2) tetramers, the beta subunit being identical to protein disulfide isomerase (PDI). The main Caenorhabditis elegans collagen P4H form is an unusual PHY-1/PHY-2/(PDI)(2) mixed tetramer consisting of two types of catalytic alpha su...

Motivation: In recent years, researchers have developed a large and growing set of protocols and algorithms to improve the throughput and capacity of wireless networks. These schemes span the physical (PHY), medium access control (MAC), and higher layers of the protocol stack. Most effective innovations however require cross-layer modifications of both PHY and higher layers. To date, the verifi...
