Multi-wavelength WiMAX-PONs with overlapping cells
(2011)An access network architecture integrating standard wireless signal formats over multi-wavelength splitter-PON based on radio over fiber (RoF) technology is demonstrated. Frequency division multiplexing (FDM) is applied ... -
Multi-wavelength wireless-PON
(Institute of Electrical and Electronics Engineers (IEEE), 2010)An innovative architectural platform demonstrating transparent transmission of frequency division multiplexed (FDM) WiMAX channels over multi-wavelength splitter-PONs enriched by overlapping cell functionalities has been ... -
A multiband 2-beam optical and infrared polarimeter
(1991)A new polarimeter capable of simultaneous observations in the U, B, V, R and I optical bands and one of the J, H, K, L and M near-infrared bands has been constructed. The polarimeter has good polarization efficiency and ... -
Multiband Fractal PIFA (Planar Inverted F Antenna) for mobile phones
(Institute of Electrical and Electronics Engineers (IEEE), 2010)A novel Fractal planar inverted F antenna F-PIFA based on the self affinity design is presented in this paper. The procedure for designing a Fractal Planar Inverted F Antenna is explained and the 2nd iteration of Sierpinski ... -
Multiband photometric decomposition of nuclear stellar disks
(2010)Context. Small, bright stellar disks with scale lengths of a few tens of parsec are known to reside in the center of galaxies. They are believed to have formed in a dissipational process as the end result of star formation ... -
Multicast polling for 10G-EPON
(2012-04)A multicast polling scheme is proposed for 10G Ethernet passive optical networks (10G-EPONs). In the multicast polling scheme, the GATE message is broadcast to all ONUs with a new op-code of 0007. Comparing the proposed ... -
Multicenter Evaluation of Neoadjuvant and Induction Gemcitabine-Carboplatin versus Gemcitabine-Cisplatin Followed by Radical Cystectomy for Muscle-Invasive Bladder Cancer
(2022-09-28)PurposeCisplatin-based chemotherapy followed by radical cystectomy (RC) is recommended in patients with muscle-invasive bladder cancer (MIBC). However, up to 50% of patients are cisplatin-ineligible. The aim of this study ... -
A multicenter feasibility randomized controlled trial to assess the impact of incremental versus conventional initiation of hemodialysis on residual kidney function
(2021-08-19)Twice-weekly hemodialysis, as part of incremental initiation, has reported benefits including preservation of residual kidney function (RKF). To explore this, we initiated a randomized controlled feasibility trial examining ... -
Multicenter, Randomized, Active Comparator-Controlled, Double-Blind, Double-Dummy, Parallel Group, Dose-Finding Phase 2 Study Comparing the Safety of the Oral FXIa Inhibitor Asundexian with Apixaban in Patients with Atrial Fibrillation
(2022-04-09)Background Direct-acting oral anticoagulant use for stroke prevention in atrial fibrillation is limited by bleeding concerns. Asundexian, a novel, oral small molecule activated coagulation factor XIa (FXIa) inhibitor, might ... -
Multichannel protocols to prevent relay attacks
(2010)A number of security systems, from Chip-and-PIN payment cards to contactless subway and train tokens, as well as secure localization systems, are vulnerable to relay attacks. Encrypting the communication between the honest ... -
Multichannel Relay assisted NOMA-ALOHA with Reinforcement Learning based Random Access
(Institute of Electrical and Electronics Engineers (IEEE), 2023-08-14)We investigate multichannel relay assisted non-orthogonal multiple access (NOMA) in slotted ALOHA systems, where each user randomly accesses one of different channel slots and different transmit power for uplink transmissions ... -
Multicriteria ranking using weights which minimize the score range
(University of Hertfordshire, 2010)Various schemes have been proposed for generating a set of non-subjective weights when aggregating multiple criteria for the purposes of ranking or selecting alternatives. The maximin approach chooses the weights which ... -
Multicultural issues in the development of a Pan-European knowledge based system
(University of Hertfordshire, 1994)This paper explores the issues involved in the development of a knowledge based system targeted for use across Europe. It draws on the experiences of the multi-national team involved in the MODEMA project, addressing issues ... -
Multidimensional histogram equalization and modification
(Institute of Electrical and Electronics Engineers (IEEE), 2007)We describe an approach toward multidimensional histogram equalization for the enhancement of color and multispectral images, based on the histogram explosion algorithm. A development from first principles is presented. ... -
Multidimensional Quantum Stochastic Integrals
(American Institute of Physics (AIP), 2011-01-01)Quantum stochastic analogues (ℋ,script A,{script A} ,m,ℝ), of a classical stochastic base may be formed whereby a classical sample space Ω is replaced by a Hilbert Space ℋ, σ-field ℱ is replaced by a von Neumann algebra ... -
A multidimensional ranking of Members of Parliament
(2022-12-01)There has been a growing trend for public accountability of those who represent or act on behalf of the general public. Whilst politicians are forever appearing in the media to justify their actions, what has been lacking ... -
