Anomalous Sequence of Quantum Hall Liquids Revealing a Tunable Lifshitz Transition in Bilayer Graphene

Fermi surface topology plays an important role in determining the electronic properties of metals. In bulk metals, the Fermi energy is not easily tunable at the energy scale needed for reaching conditions for the Lifshitz transition - a singular point in the band structure where the connectivity of the Fermi surface changes. Bilayer graphene is a unique system where both Fermi energy and the low-energy electron dispersion can be tuned using the interplay between trigonal warping and a band gap opened by a transverse electric field. Here, we drive the Lifshitz transition to experimentally controllable carrier densities by applying large transverse electric fields through a h-BN-encapsulated bilayer graphene structure, and detect it by measuring the degeneracies of Landau levels. These degeneracies are revealed by filling factor -3 and -6 quantum Hall effect states of holes at low magnetic fields reflecting the existence of three maxima on the top of the valence band dispersion. At high magnetic fields all integer quantum Hall states are observed, indicating that deeper in the valence band the constant energy contours are singly-connected. The fact that we observe ferromagnetic quantum Hall states at odd-integer filling factors testifies to the high quality of our sample, and this enables us to identify several phase transitions between correlated quantum Hall states at intermediate magnetic fields, in agreement with the calculated evolution of the Landau level spectrum.
Fast protein structure alignment using Gaussian overlap scoring of backbone peptide fragment similarity

Aligning and comparing protein structures is important for understanding their evolutionary and functional relationships. With the rapid growth of protein structure databases in recent years, the need to align, superpose and compare protein structures rapidly and accurately has never been greater. Many structural alignment algorithms have been described in the past 20 years. However, achieving an algorithm that is both accurate and fast remains a considerable challenge.We have developed a novel protein structure alignment algorithm called 'Kpax', which exploits the highly predictable covalent geometry of C(α) atoms to define multiple local coordinate frames in which backbone peptide fragments may be oriented and compared using sensitive Gaussian overlap scoring functions. A global alignment and hence a structural superposition may then be found rapidly using dynamic programming with secondary structure-specific gap penalties. When superposing pairs of structures, Kpax tends to give tighter secondary structure overlays than several popular structure alignment algorithms. When searching the CATH database, Kpax is faster and more accurate than the very efficient Yakusa algorithm, and it gives almost the same high level of fold recognition as TM-Align while being more than 100 times faster.

Carbon nanotube bearings in theory and practice

Carbon Nanotubes (CNTs) are attractive elements for
bearings in Micro-Electro-Mechanical Systems (MEMS), because their
structure comprises nested shells with no bonding and sub-nanometer
spacing between them, enabling relative motion with low friction
and wear. A few demonstrations of CNT bearings have been reported
in the literature, and atomistic simulations have been used to
probe the properties of these bearings. This thesis extends the
state of knowledge about these bearing systems, by building on
these prior works in both the experimental and simulation domains.
The prototype CNT rotor device presented in this thesis, and
accompanying fabrication process, improve on existing CNT bearing
demonstrators by establishing a vertical bearing orientation
(enabling superior rotor balance and speed, and flexibility of
placement for drive mechanisms) and a more manufacturable process
(employing CNTs grown in place by chemical vapor deposition, and
evaluating trade-offs in growth parameters). The device consists of
a silicon rotor, supported on a cantilevered CNT shaft, and
actuated by impingement of air jets on blades around its perimeter.
For the fabrication development, extensive and consistent studies
on the compatibility of CNTs with a suite of standard MEMS process
were conducted, yielding valuable information for future CNT-based
device designers on the effects of these processes on CNTs.
Additionally, manual manipulation and placement of loose CNTs into
the required vertical alignment was demonstrated, providing an
alternate fabrication route, as well as a useful research technique
for development of CNT devices. Simulation of friction in a CNT
bearing system has been a popular topic, yet many questions remain
open. For example, the quantitative estimates of this friction
reported to date range by as much as eight orders of magnitude, and
simulation techniques employ a variety of disparate simulation
paradigms and parameters. This thesis presents a new suite of
consistently implemented but complementary and independent
simulations, which span the approaches reported to date, yet agree
quantitatively within the error margin. Furthermore, the
quantitative relationships between friction and sliding speed,
temperature, geometry, and simulation implementation parameters are
determined, and a description of the causes of friction based on
phonon analyses is offered.
Suivi des variables hydrologiques par télédétection et modélisation dans le bassin du fleuve Congo

Cette étude a pour but d'intégrer des observations hétérogènes de télédétection et la modélisation hydrologique dans un cadre simple pour le suivi des variables hydrologiques dans le bassin du fleuve Congo (CRB), qui est peu jaugé. Elle se concentre sur la possibilité d'estimer les profondeurs et les débits effectifs des rivières sur l'ensemble du bassin en temps quasi réel (NRT). Tout d'abord, cet article traite de la complexité de la calibration et de la validation d'un modèle hydrologique-hydrodynamique (à savoir le modèle MGB) dans le CRB. Ensuite, il fournit une double méthodologie pour déduire le débit aux stations virtuelles nouvellement surveillées (VSs, croisements d'une trace au sol du satellite avec un corps d'eau). Il y est fait usage d'un ensemble de données de télédétection et de données in situ pour contraindre, calibrer et valider le modèle, et aussi pour construire un jeu de données de courbes de tarage hauteur/débit (RC) à 709 VSs localisées dans tout le bassin. Le modèle a été bien calibré aux quatre jauges avec des données récentes (efficacité de Nash-Sutcliffe, NSE > 0.77). La qualité satisfaisante des RC à l’échelle du bassin (NSE moyen entre le débit simulé et le débit par CT et altimétrie aux VS, NSE moyen = 0.67) est un indicateur de la cohérence globale des simulations de débit, même dans les sous-bassins amont non jaugés. Cet base de données de RC offre une possibilité sans précédent de suivi NRT de l’état hydrologique du CRB à partir de la constellation opérationnelle actuelle de satellites altimétriques. Les débits estimés aux endroits nouvellement surveillés se sont avérés cohérents avec les observations. Ils peuvent être utilisés pour augmenter l’échantillonnage temporel de la surveillance de l’élévation de la surface de l'eau (WSE) depuis l'espace sans avoir besoin d'exécuter de nouveaux modèles. La RC située sous l'orbite d'échantillonnage rapide du satellite SWOT, qui sera lancé en 2022, sera utilisée pour déduire le débit quotidien dans les principaux contributeurs et dans la Cuvette Centrale, dès que les données seront disponibles.

The cChromic shaped bricks have been used as the refractory lining in alumina kiln for long time, whose service life is about 120~250 days. Besides the short working time, the environmental pollution led to by the chromic component is also serious. In this thesispaper (thesis 是硕士论文), some materials are were chosen based on the actual situation of the usage of the refractory lining in the current alumina kiln. The choosing principals are were the extensive source and the relatively low price. Finally, a new formula of the refractory castable is was acquired based on the orthogonal test and has passed the properties testing.
Agent-Based System Design for Service Process Scheduling: Challenges, Approaches and Opportunities

Compared with traditional manufacturing scheduling, service process scheduling poses additional challenges attributable to the significant customer involvement in service processes. In services, there are typically no inventoried products, which make the service provider's capacity more sensitive to dynamic changes. Service process scheduling objectives are also more complicated due to the consideration of customer preferences, customer waiting costs and human resource costs. After describing the Unified Services Theory and analysing its scheduling implications, this paper reviews the research literature on service process scheduling system design with a particular emphasis on agent-based approaches. Major issues in agent-based service process scheduling systems design are discussed and research opportunities are identified. The survey of the literature reveals that despite of many domain-specific designs in agent-based service process scheduling, there is a lack of general problem formulations, classifications, solution frameworks, and test beds. Constructing these general models for service process scheduling system design will facilitate the collaboration of researchers in this area and guide the effective development of integrated service process scheduling systems.

Sustainable Mobility in the Port Cities of the Southern Adriatic Area

SUMO project involves some of the main port cities of the Southern Adriatic area: Termoli, Brindisi, Bar, Valona. SUMO project aims to improve sustainability and mobility relative to the port areas of the area starting from the problems and solutions identified in the European strategy in the field of "Mobility and Transport" , through the analysis of the state of the art of the port areas involved in the project. In fact for Europe the maritime transport has been considerate a catalyst for economic development, moreover almost 90% of the EU’s external freight trade is seaborne and short sea shipping represents one third of intra-EU exchanges in terms of ton-kilometers. For this ensuring a good quality of life on Europe’s islands and in peripheral maritime regions depends on good and green maritime transport services and it is one of the important objectives of Europe Strategy. In this sense the project Sumo poses two important challenges: to improve transport efficiency, in terms of sustainability and quality, through pilot actions in each area of the program involved, and to develop an efficient planning ciruit for sustainable mobility. Thus triggering a long-term network for the program area regions involved in the project. The main objective of SUMO is to support the bodies involved in the process of transition to sustainable mobility, and at the same time favour at the final users the sustainable and efficient intermodality services. The pilot action consist of the purchase of innovative equipments able to improve sustainability and mobility in the port cities involved in the project, with a relevant reduction of air pollutant emissions. Strength of the project is the fact that all the pilot actions result replicable  and already completely defined for their implementation, in the first 6 months of the project, respecting the foreseen timeline of 18 months. Crucially, the specific competences of each PPs ensure the suistainability of the project results.
DESIGN AND PERFORMANCE EVALUATION OF A PLANT FOR GLYCEROL CONVERSION TO ACROLEIN

The development of biodiesel industry in the recent past brought into discussion the valorization of glycerol as the byproduct of this technology. Dehydration of glycerol leads to acrolein, mainly used as a raw material in the production of acrylic acid and its esters. Several research efforts dealing with the synthesis of acrolein from glycerol are reported in the literature. However, they are limited to catalyst testing on laboratory scale, no attention being paid to the process feasibility at an industrial scale. The goal of this paper is to fill this gap by presenting an integrated design study of the glycerol dehydration process. A simplified kinetic model was developed based on published data, this one being able to predict with sufficient accuracy the rate of the main reaction and the formation of relevant by-products (carbonyl compounds, hydrocarbons, carbon monoxide and coke). A reaction system was designed, similar to the reactor-regenerator unit usually used in hydrocarbon catalytic cracking (FCC). Moreover, the operating conditions were determined in such a way to maximize the selectivity and ensure the autothermal operation. The reactor effluent is sent to a separation section consisting mainly in distillation units. Due to formation of a low-boiling azeotrope, extractive distillation is employed for separating the acrolein-water mixture, using a part of the fresh glycerol feed as solvent. For a set of typical operating conditions, the separation section was designed in Aspen Plus environment. An economic evaluation study was performed using Aspen Economic Evaluation module, following which an acrolein price of 1.13 EUR/kg was determined. By comparing this value with the market one of 3.3 EUR/kg, the feasibility of the proposed process from the economical point of view will be emphasized.
Emotional implications of the arrival of a sibling for the firstborn: a literature review

The birth of a second child is a specific phase of the family life cycle, which brings changes, especially for the firstborn. The present article examines some theoretical questions and empirical studies concerning the emotional implications of the birth of a second child for the firstborn. The studies suggest that this is a special moment both for mothers, who need to take care of two children, and for the firstborn who is no longer an only child and needs to share maternal care. The literature on the impact of the birth of a second child on the firstborn has presented contradictory results. If, on the one hand, it has highlighted the firstborn’s greater dependence and regressive behaviours, on the other, it has indicated more independent behaviours. Moreover, the literature considers dependence behaviours as negative, while independence behaviours are seen as positive and a sign of growth. It is fundamental to identify transition points in the family cycle, so as to help parents to understand that the child follows its own rhythm of development towards independence, and may present more regressive behaviours in moments of transition.
The first b2b marketplace for fast moving consumer goods, connecting all brand manufacturers and retailers globally

Fast Moving Consumer Goods (FMCGs) are products sold quickly at relatively low prices, like foods, beverages, and toiletries. Most people consume FMCGs every day. Despite the huge size of this market, FMCG producers and retailers experience a number of challenges. First, the need for more product data is continuously growing due to legal and consumer expectations. Second, there is no commonly agreed structure for product information exchange between producers and retailers. Plus, current processes are inadequate for big data exchange, since they are mostly performed manually and, thus, more error-prone.

Alkemics has developed a Peer-to-Peer platform to overcome these challenges. B2BMarketplace is the first and unique global B2B marketplace for FMCGs. It connects retailers and producers to sell and buy FMCG goods. It enables producers to get their products discovered by retailers, streamline product data exchange in order to accelerate product launch, and increase the quality of the product content across the retailer ecosystem. At the core of B2BMarketplace lie Alkemics’ unique algorithms which allow the automated product information sharing by translating the inserted ‘raw product data’ into data that is compatible with the common systems used by the stakeholders of the marketplace.

Alkemics is a French start-up founded in 2011 and focused on Artificial Intelligence for Big Data exchange. The company is already serving two European key FMCG markets (France and UK) and working with several important retailers (Tesco, Carrefour) and multinational producers (Nestlé, Unilever). It is supported by the recognised GS1 Organisation, which develops global standards for business operations. 

The proposed work in Phase 1 of the SME Instrument fits into Alkemics' overall plan to reach the market by contributing the financial resources needed to plan a fast, sound deployment of B2BMarketplace.
Los museos militares y el turismo. El caso de la Sala-museo del Automóvil (Torrejón de Ardoz) y su gestión turística

The purpose of military museums is to transmit a democratic culture of defence. The boom in cul‑ tural tourism, as well as the use of museums as tourist resources, may be an opportunity for the Ministry of Defence museums to increase their audiences. The purpose of this work is to establish possible links between military museums and tourism in order to see if these institutions could benefit in the future from such a relationship. The research focused on the Automobile Museum of Torrejón de Ardoz as a model for this type of institution, analysing its current situation with respect to the public and the possibilities that it might offer with adequate tourism management. The methodology was based on questionnaires, interviews and direct observation, and may be applicable to other small and medium‑sized museum institutions with low demand. Among the main conclusions we have reached, we would like to highlight that there are many improvements that should be introduced by this type of museum, if they are really interested in increasing the number and di‑ versity of visitors, opening up to tourism and thus transmitting an idea of a renewed present culture of defence.
