CMOS plasmonics in WDM data transmission: 200 Gb/s (8 × 25Gb/s) transmission over aluminum plasmonic waveguides
2018
We demonstrate wavelength-division-multiplexed (WDM) 200 Gb/s (8 × 25 Gb/s) data transmission over 100 μm long aluminum (Al) surface-plasmon-polariton (SPP) waveguides on a Si3N4 waveguide platform at telecom wavelengths. The Al SPP waveguide was evaluated in terms of signal integrity by performing bit-error-rate (BER) measurements that revealed error-free operation for all eight 25 Gb/s non-return-to-zero (NRZ) modulated data channels with power penalties not exceeding 0.2 dB at 10−9. To the best of our knowledge, this is the first demonstration of WDM enabled data transmission over complementary-metal-oxide-semiconductor (CMOS) SPP waveguides fueling future development of CMOS compatible …
23.1: Invited Paper: Models and Experiments of Mechanical Integrity for Flexible Displays
2008
Flexible displays present a challenging problem in terms of mechanical integrity, a result of the considerable hygro-thermo-mechanical contrast between the inorganic, brittle device layers and the compliant polymer substrates. This paper reviews the main approaches to study and identify the key factors, which control the mechanical stability of this class of displays. Focus is put on the analyses of residual stress and damage under tensile loading. Novel electro-mechanical methods are used for accurate insight into critical phenomena. An important result is that the thickness and stiffness of the substrate control the critical strain for failure of the device layers.
Evaluation of the apical sealing ability and adaptation to the dentin of two resin-based Sealers: An in vitro study
2013
Aim: To quantitatively evaluate the apical sealing ability and adaptation of two resin-based sealers to dentin. Materials and Methods: Fifty freshly extracted mandibular first premolars were taken and sectioned at the cemento-enamel junction. Thirty teeth were subjected to a leakage study by the resin infiltration method with two groups of 10 teeth each. Group I teeth were obturated with methacrylate resin-based sealer (EnoRez) and Group II teeth were obturated with epoxy resin-based sealer (AH Plus). The remaining 10 teeth were used as controls (positive and negative of five teeth each). Twenty teeth were divided into two groups and obturated as in the leakage study and subjected to a scan…
Monitoring Human Viral Pathogens Reveals Potential Hazard for Treated Wastewater Discharge or Reuse
2022
Wastewater discharge to the environment or its reuse after sanitization poses a concern for public health given the risk of transmission of human viral diseases. However, estimating the viral infectivity along the wastewater cycle presents technical challenges and still remains underexplored. Recently, human-associated crAssphage has been investigated to serve as viral pathogen indicator to monitor fecal impacted water bodies, even though its assessment as biomarker for infectious enteric viruses has not been explored yet. To this end, the occurrence of potentially infectious norovirus genogroup I (GI), norovirus GII, hepatitis A virus (HAV), rotavirus A (RV), and human astrovirus (HAstV) a…
Optical Link Card Design for the Phase II Upgrade of TileCal Experiment
2011
This paper presents the design of an optical link card developed in the frame of the R&D activities for the phase 2 upgrade of the TileCal experiment. This board, that is part of the evaluation of different technologies for the final choice in the next years, is designed as a mezzanine that can work independently or be plugged in the optical multiplexer board of the TileCal backend electronics. It includes two SNAP 12 optical connectors able to transmit and receive up to 75 Gb/s and one SFP optical connector for lower speeds and compatibility with existing hardware as the read out driver. All processing is done in a Stratix II GX field-programmable gate array (FPGA). Details are given on th…
Multiphysics Optimization for First Wall Design Enhancement in Water-Cooled Breeding Blankets
2021
Abstract The commercial feasibility of the first fusion power plant generation adopting D-T plasma is strongly dependent upon the self-sustainability in terms of tritium fuelling. Within such a kind of reactor, the component selected to house the tritium breeding reactions is the breeding blanket, which is further assigned to heat power removal and radiation shielding functions. As a consequence of both its role and position, the breeding blanket is heavily exposed to both surface and volumetric heat loads and, hence, its design requires a typical multiphysics approach, from the neutronics to the thermo-mechanics. During last years, a great deal of effort has been put in the optimization of…
The Topological Processor for the future ATLAS Level-1 Trigger: From design to commissioning
2014
The ATLAS detector at the Large Hadron Collider (LHC) is designed to measure decay properties of high energetic particles produced in the proton-proton collisions. During its first run, the LHC collided proton bunches at a frequency of 20 MHz, and therefore the detector required a Trigger system to efficiently select events down to a manageable event storage rate of about 400 Hz. By 2015 the LHC instantaneous luminosity will be increased up to 3×1034cm−2s−1: this represents an unprecedented challenge faced by the ATLAS Trigger system. To cope with the higher event rate and efficiently select relevant events from a physics point of view, a new element will be included in the Level-1 Trigger …
Empowerment – a Double Edged Sword?
2015
The concept of empowerment is a democratic tool and a logical next step in the evolution of public administration. In this article we explore the possibility of this concept to be used as a tool of unconventional warfare under a certain set of conditions. The carried out case study of the recent events in Ukraine, Crimea allows to conclude that empowerment can indeed be used to compromise the territorial integrity of a sovereign country.
The Correlation of the Principles of International Law in the Context of Nagorno-Karabagh Conflict Resolution
2009
The Nagorno-Karabakh conflict is one of the most bloody and large-scale conflicts in the post-Soviet region. This is an old conflict with its own genesis and internal dynamics. The conflict is considered to be a real obstacle to the normalization of relations between Armenia and Azerbaijan. Different political and economic factors play a major role in the regulation of the Nagorno-Karabakh conflict: the geostrategic interests of regional hegemons and the question of who controls its oil riches. Not surprisingly, the process of conflict regulation in Nagorno-Karabakh is a highly politicized issue. To date, little or no attention has been paid to the legal aspects of the conflict, and the pos…
The impact of foreign language mediated teaching on teachers’ sense of professional integrity in the CLIL classroom
2011
Content and language integrated learning (CLIL) has received significant interest in recent years as a practical means of creating a plurilingual European community. A key feature of CLIL is the non-native speaking teacher responsible for developing learners’ content and language knowledge in a foreign language mediated environment. Teachers often enter the CLIL classroom with established expertise in either content or language learning; however, the impact of entering the foreign language mediated environment is little explored in existing literature. This investigative research is based on six teacher interviews intended to access the teachers’ own understanding of how foreign language me…
