The Contentious Roots of the Egyptian Revolution

AbstractAlthough real socio-economic injustices may have been the justification for the Egyptian revolution of 2011, it was not the cause of Egypt's politicization. Demonstrators peacefully toppled a strong Western ally on the premise of high unemployment, lack of opportunity, lack of free elections, food inflation, corruption, and lack of democracy, among other factors. Why did social mobilization lead to a social movement against a state that is highly dependent on coercion? Considering that access to social networks, high unemployment, systematic corruption, and economic stagnation are all commonplace throughout the world, the Egyptian revolution is an anomaly. This article argues that an analysis of the possible roots of the modern era of contentious politics in Egypt and its subsequent politicization will help demystify and decipher how this anomaly occurred. Focusing on the transnationally inspired dynamics of historically unprecedented protest events in relation to Egypt's political and social cont...
Assessment of regional myocardial wall stress before and after surgical correction of functional ischaemic mitral regurgitation using multidetector computed tomography and novel software system☆☆☆

The objective of this study was to assess changes in left ventricular (LV) volume, function and regional myocardial wall stress in non-infarcted segments following restrictive mitral annuloplasty (RMA) in patients with ischaemic cardiomyopathy (ICM) and severe functional mitral regurgitation (MR).Twenty-two patients with ICM (ejection fraction <35%) and severe MR were investigated before and 3 months after RMA using cine-angiographic multidetector row computed tomography (cine-MDCT). For comparative purposes, 38 normal subjects were also studied. Cine-MDCT LV images were reconstructed in a cardiac cycle and regional circumferential wall stress (end-systolic stress (ESS)) was evaluated from the LV end-systolic image using Janz's method. The ESS was determined in six basal and six mid-LV segments of the ventricle based on AHA/ASE criteria. Five apical infarcted segments were not analysed. Mean circumferential fibre shortening (CFS) in both basal and mid-LV regions was determined as a parameter of regional systolic performance.Left ventricular end-diastolic volume (index) (LVEDVI) and left ventricular end-systolic volume (index) (LVESVI) decreased significantly and left ventricular ejection fraction (LVEF) increased after surgery. Neither end-systolic nor end-diastolic sphericity index changed significantly after surgery. Regional ESS significantly decreased in both basal and mid-LV regions after surgery. There was a significant inverse correlation between the change in average value of regional ESS and magnitude of increase in mean CFS of the mid-LV region (r=-0.67, p=0.0018). Postoperative reduction in ESS in the mid-LV region was also correlated with improvement in global EF (r=-0.72, p<0.01).The present cine-MDCT may be useful for assessing regional myocardial stress in patients with ICM. We found that RMA could reduce both end-diastolic and end-systolic volume leading to reduction in regional systolic wall stress, which resulted in improved ejection performance of non-infarcted myocardium in patients with functional MR and ICM.
Modeling and simulation of organic solar cells

We present our investigation of organic solar cells by modeling and simulation after numerically solving Poisson and continuity equations that describe the electric property of semiconductors. Specifically, simulations reveal that Langevin type recombination, which describes the loss mechanism in pristine materials with low mobility, is not proper to predict the performance of BHJ organic solar cells and will lead counterintuitive simulation results. Then, the recombination mechanism has been studied in bulk heterojunction (BHJ) organic solar cells by simulating intensity-dependent current-voltage (J-V) measurements. The simulation results indicate that primary loss mechanism is monomolecular recombination. Moreover, the unbalanced carrier transport in organic solar cells is explored and the simulation suggests that increasing hole mobility is an effective method to improve the performance of organic solar cells.
Molecular simulations of peptides and proteins with Molecular Fragment Dynamics (MFD)

Molecular Fragment Dynamics (MFD) is a mesoscopic simulation technique based on dissipative particle dynamics. The method has been shown to successfully describe the phase behaviour and interfacial tensions of large chemical systems in good agreement with experimental results [1]. Unlike molecular mechanics a MFD simulation is based on coarse-grained molecular fragments rather than fine-grained atom types.

The current MFD fragment definition is based on a SMILES like one-dimensional line notation which is visualized with the Structure Diagram Generator of the Chemistry Development Kit (CDK) [2]. For an extension of the MFD technique to chemical ensembles containing peptides and proteins an appropriate molecular fragment cheminformatics tool for their design is in need.

This work provides an editor for the construction of peptides and proteins from molecular fragments. It includes building blocks for all 20 proteinogenic amino acids, their charged species and disulfide bonds. A flexible input of one-letter and three-letter amino acid codes is supported. Additionally, the editor has the capability to set charges of side chains manually or automatically.
Long distance telephone switching system with enhanced subscriber services

A long distance telephone switching system is adapted to provide various enhanced subscriber services, such as an audio news and information service, conference calling, voice messaging, message storage and forwarding, and speed dialing, in addition to conventional long distance calling. Additional improvements include the use of pre-recorded opening and closing scripts to facilitate the handling of operator-assisted calls, the retrieval of stored subscriber billing data prior to each call reorigination in order to detect instances of possible abuse, and the concatenation of subscriber-input authorization codes with access number data to allow the use of shorter authorization codes by the subscribers.
Algebraic and kähler geometry

The purpose of this project is to study basic questions in algebraic and Kähler geometry. It is well known that the structure of projective or Kähler manifolds is governed by positivity or negativity properties of the curvature tensor. However, many fundamental problems are still wide open. Since the mid 1980's, I have developed a large number of key concepts and results that have led to important progress in transcendental algebraic geometry. Let me mention the discovery of holomorphic Morse inequalities, systematic applications of L² estimates with singular hermitian metrics, and a much improved understanding of Monge-Ampère equations and of singularities of plurisuharmonic functions.  My first goal will be to investigate the Green-Griffiths-Lang conjecture asserting that an entire curve drawn in a variety of general type is algebraically degenerate. The subject is intimately related to important questions concerning Diophantine equations, especially higher dimensional generalizations of Faltings' theorem - the so-called Vojta program. One can rely here on a breakthrough I made in 2010, showing that all such entire curves must satisfy algebraic differential equations. A second closely related area of research of this project is the analysis of the structure of projective or compact Kähler manifolds. It can be seen as a generalization of the classification theory of surfaces by Kodaira, and of the more recent results for dimension 3 (Kawamata, Kollár, Mori, Shokurov, ...) to other dimensions. My plan is to combine powerful recent results obtained on the duality of positive cohomology cones with an analysis of the instability of the tangent bundle, i.e. of the Harder-Narasimhan filtration. On these ground-breaking questions, I intend  to go much further and to enhance my national and international collaborations. These subjects already attract many young researchers and postdocs throughout the world, and the grant could be used to create even stronger interactions.
Smart voltage control in distribution networks with a large share of distributed renewable generation

Traditionally, voltage control in medium voltage (MV) distribution networks has been focused on dealing with voltage drops along radially operated feeders. The presence of distributed renewable generation (DRG) can introduce voltage rise issues, thus complicating voltage control in distribution systems. The proposed coordinated voltage control strategy deploys control of HV/MV transformers On-Load Tap Changers in combination with active power control provided by Intelligent Nodes, which also allow for network reconfiguration. The analysis of simulation results shows that the proposed voltage control strategy is capable of facilitating the transition towards active distribution networks, by offering considerably higher DRG penetration levels while maintaining strictly bound node voltages. The limiting factors for an increased DRG penetration are identified, as well as the effects of reactive power control. The modelled controller is particularly applicable to MV distribution networks across North Europe.
Development of biomolecular tools for the spatiotemporal photocontrol of ampa receptors mobility

The PhotoXLink project aims to develop original tools to elucidate the role of various AMPA receptor mediated forms of plasticity in both physiological and pathological situations. AMPAR is a transmembrane ionotropic receptor for glutamate molecule that mediates most fast excitatory synaptic transmission in the mammalian central nervous system. Its regulation is vital for their synaptic function, which underlies memory and learning theories. In the PhotoXLink project, we propose to engineer novel optogenetic tools (photocrosslinkers) that will specifically recognize AMPAR subunits and control their oligomeric state with spatial and temporal resolution. The photocrosslinkers will hence provide a unique control locally, acutely and in a reversible manner on the mobility and local number of AMPARs. The development of these photocrosslinkers will address current technical limitations and ultimately allow investigating with an unprecedented spatiotemporal resolution the impact of AMPARs mobility in short and long term plasticity in the brain function. 
The multidisciplinary nature of the project is strong, involving molecular/cell biology, biochemistry and protein engineering for the design and production of the tools and advanced fluorescence imaging techniques for validating them in cellular context. It will be carried out at an internationally recognized neuroscience institute that will enhance my skills and diversify my individual competences through advanced training and quality research for improving my future career development. My expertise in photochemistry and photobiology combined with the host´s in neurobiology and protein engineering ensures the best chance for successfully fulfil the goals of the PhotoXLink project. This project is in line with the brain research priority for EU research funding.
Adhesion and differentiation of human mesenchymal stem cells on plasma-functionalized graphenes with different feeding gases

Abstract Surface functionalisation of graphene layer has been investigated to improve the efficiencies in bio-applications such as stem cell differentiation or protein sensing. Plasma treatment can induce various functionalities on graphene surface simply by changing feeding gas. In this study, the surface chemistry of graphene is modified by plasma treatment using three different feeding gases of H2, N2, and O2. The effects of differential functionalisation are examined by the adsorption of fibronectin and the adhesion, proliferation, and differentiation of human mesenchymal stem cells. Fibronection adsorption is enhanced on the N2 plasma-treated graphene, but it is not clear on the others. hMSCs adhesion is broadened on all of the plasma-treated graphene substrates, especially on the N2 plasma-treated one. H2 plasma treatment enhances cell proliferation and osteogenic differentiation, and N2 and O2 plasma treatments show a tendency of heterogeneous differentiation to osteoblasts and myoblasts. Different responses of stem cell adhesion, proliferation, and differentiation depending on the plasma-treated graphene surface indicate the importance of highly specific surface functionality in stem cell engineering.

The Effects of Descriptive Associational Leadership on Civic Engagement: The Case of Clergy and Gender in Protestant Denominations

Given the attention that has been paid to the presence of women in leadership positions throughout the economy and society as well as the role that associations play in shaping citizen political participation, it is surprising that their confluence has not been systematically studied. What effect does men's versus women's associational leadership have on the political engagement of women and men members? Using a set of surveys drawn from Protestant denominations that ordain women as part of the 2001 U.S. Congregational Life Study, I investigate clergy gender effects on church leadership and political participation conditional on member gender using hierarchical models. Across four denominations, I find descriptive evidence but little systematic evidence supporting an effect due to clergy gender, though somewhat more evidence on church leadership than on political activity.
Intra-parasequence architecture of an interpreted asymmetrical wave-dominated delta

Although modern wave-dominated shorelines exhibit complex geomorphologies, their ancient counterparts are typically described in terms of shoreface-shelf parasequences with a simple internal architecture. This discrepancy can lead to poor discrimination between, and incorrect identification of, different types of wave-dominated shoreline in the stratigraphic record. Documented in this paper are the variability in facies characteristics, high-resolution stratigraphic architecture and interpreted palaeo-geomorphology within a single parasequence that is interpreted to record the advance of an ancient asymmetrical wave-dominated delta. The Standardville (Ab1) parasequence of the Aberdeen Member, Blackhawk Formation is exposed in the Book Cliffs of central Utah, USA. This parasequence, and four others in the Aberdeen Member, record the eastward progradation of north/south-trending, wave-dominated shorelines. Within the Standardville (Ab1) parasequence, distal wave-dominated shoreface-shelf deposits in the eastern part of the study area are overlain across a downlap surface by southward prograding fluvial-dominated delta-front deposits, which have previously been assigned to a separate ‘stranded lowstand parasequence’ formed by a significant, allogenic change in relative sea-level. High-resolution stratigraphic analysis of these deposits reveals that they are instead more likely to record a single episode of shoreline progradation characterized by alternating periods of normal regressive and forced regressive shoreline trajectory because of minor cyclical fluctuations in relative sea-level. Interpreted normal regressive shoreline trajectories within the wave-dominated shoreface-shelf deposits are marked by aggradational stacking of bedsets bounded by non-depositional discontinuity surfaces. Interpreted forced regressive shoreline trajectories in the same deposits are characterized by shallow incision of fluvial distributary channels and strongly progradational stacking of bedsets bounded by erosional discontinuity surfaces that record enhanced wave-base scour. Fluvial-dominated delta-front deposits most probably record the regression of a lobate delta parallel to the regional shoreline into an embayment that was sheltered from wave influence. Wave-dominated shoreface-shelf and fluvial-dominated delta-front deposits occur within the same parasequence, and their interpretation as the respective updrift and downdrift flanks of a single asymmetrical wave-dominated delta that periodically shifted its position provides the most straightforward explanation of the distribution and relative orientation of these two deposit types.
Mind and time: investigation of the temporal traits of human-machine convergence

Contemporary research endeavours aim at equipping artificial systems with human-like cognitive skills, in an attempt to promote their intelligence beyond repetitive task accomplishment. However, despite the crucial role that the sense of time has in human cognition, both in perception and action, the capacity of artificial agents to experience the flow of time remains largely unexplored. The inability of existing systems to perceive time constrains their potential understanding of the inherent temporal characteristics of the dynamic world, which in turn acts as an obstacle to their symbiosis with humans. Time perception is without doubt, not an optional extra, but a necessity for the development of truly autonomous, cognitive machines.
TIMESTORM aims at bridging this fundamental gap by shifting the focus of human-machine confluence to the temporal, short- and long-term aspects of symbiotic interaction. The integrative pursuit of research and technological developments in time perception will contribute significantly to ongoing efforts in deciphering the relevant brain circuitry and will also give rise to innovative implementations of artifacts with profoundly enhanced cognitive capacities.
Equipping artificial agents with temporal cognition establishes a new framework for the investigation and integration of knowing, doing, and being in artificial systems. The proposed research will study the principles of time processing in the human brain and their replication in-silico, adopting a multidisciplinary research approach that involves developmental studies, brain imaging, computational modelling and embodied experiments. By investigating artificial temporal cognition, TIMESTORM inaugurates a novel research field in cognitive systems with the potential to contribute to the advent of next generation intelligent systems, significantly promoting the seamless integration of artificial agents in human societies.
Analysis of tropical peatland fire risk using drought standardized precipitation index method and TRMM rainfall data

The area of peatlands in Indonesia is about 20 million hectares or about 10.5% of the total land area of Indonesia, which is spread on the islands of Sumatra, Kalimantan and Papua. Almost every year, these peatlands experience fires in various places. The great fires that occurred in most of Indonesia's peatlands have occurred in 2014 and 2015 which caused severe haze disasters, especially on the islands of Sumatra and Kalimantan, even to neighboring country. The peatland fires continue to recur, which usually occurs in the dry season. In what kind of dryness level that usually peatland fires starting to occur, was analyzed in this study. The analysis was carried out using the drought index of SPI (Standardized Precipitation Index) method and TRMM (Tropical Rainfall Measuring Mission) rainfall data. The study was focused on the Bengkalis Island, which the peatland covered about 90% of the total area of Bengkalis Island. The analysis of SPI was carried out on a half monthly and monthly period for each grid with longitude and latitude size of 0.1° x 0.1°, so that the Bengkalis Island area was divided into 13 grids. TRMM data were downloaded using FileZilla and were analyzed using the Command Prompt application and the GrADS (The Grid Analysis and Display System) application. The values of SPIs were categorized as extremely wet, very wet, moderately wet, Mildly wet, mild wet, moderate drought, severe drought, and extreme drought. The spatial and temporal distribution of SPI were then compared with the historical data of fire events originating from hotspots. This study found that the peatlands start to be high risk against peat fire on meteorological drought index of SPI number of 0.5 with the status of “near normal”. The other factors can generate the fire event such as the level of degraded peatland, over-drained peatland, peat thickness, social economic, lack of law enforcement and culture. However, it is important to note that to keep peatlands not burned is always keeping peatlands wet with the application of a good water management system.
Harvesting low-frequency acoustic energy using quarter-wavelength straight-tube acoustic resonator

Abstract An acoustic energy harvester is introduced that uses a quarter-wavelength straight-tube acoustic resonator with polyvinylidene fluoride (PVDF) piezoelectric cantilever beams placed inside the resonator. When the tube is excited by an incident wave at its first acoustic eigenfrequency, an amplified acoustic resonant standing wave is developed inside the tube. The acoustic pressure gradient of the amplified standing wave then drives the vibration motion of the PVDF piezoelectric beams, generating electricity due to the direct piezoelectric effect. In order to maximize the amount of the harvested energy, each PVDF piezoelectric beam has been designed to have the same structural eigenfrequency as the acoustic eigenfrequency of the tube. With a single PVDF beam placed inside the tube, the harvested voltage and power become the maximum near the tube open inlet where the largest acoustic pressure gradient vibrates the PVDF beam. As the beam is moved to the tube closed end, the voltage and power gradually decrease due to the decreased acoustic pressure gradient. Multiple piezoelectric beams have been placed inside the tube with two different configurations: the aligned and zigzag configurations. With the zigzag configuration which has the more open path for acoustic air particle motions, the significant increases in the harvested voltage and power have been observed. Due to the interruption of acoustic air particle motion caused by the beams, it is found that placing PVDF beams near the closed tube end is not beneficial. The total output voltage of the piezoelectric beams increases linearly as the incident sound pressure increases.
Impact of environmental moisture on C3A polymorphs in the absence and presence of CaSO4· 0·5 H2O

The phenomenon of water vapour sorption by anhydrous C3A polymorphs both in the absence and in the presence of CaSO4·0·5 H2O was studied utilising dynamic and static sorption methods. It was found that orthorhombic C3A starts to sorb water at 55% relative humidity (RH) and cubic C3A at 80% RH. Also, C3Ao sorbs a higher amount of water which is predominantly physically bound, whereas C3Ac preferentially interacts with water by chemical reaction. In the presence of calcium sulfate hemihydrate, ettringite was observed as the predominant pre-hydration product for both C3A modifications: that is, ion transport had occurred between C3A and sulfate. Environmental scanning electron microscopic imaging revealed that in a moist atmosphere, a liquid water film condenses on the surface of the phases as a consequence of capillary condensation between the particles. C3A and sulfate can then dissolve and react with each other. Seemingly, pre-hydration is mainly facilitated through capillary condensation and less through...
