The people behind the papers – Léa Rambaud-Lavigne, Namrata Gundiah, Arezki Boudaoud and Pradeep Das
No full textInternational audienceThe shoot apical meristem is a key stem cell niche in plants, and proper stem cell maintenance is partly regulated by CLAVATA3 (CLV3). Without CLV3 meristems overgrow, but the mechanistic basis of this phenotype was unclear. A new paper in Development suggests that CLV3 modulates the physical properties of meristematic stem cells, and that these properties help shape meristem morphology. To learn more about the story behind the paper, we caught up with first author Léa Rambaud-Lavigne and corresponding authors Namrata Gundiah, Arezki Boudaoud and Pradeep Das

The combined incidence of taxes and public expenditures in the Philippines
No full textIncidence studies of fiscal policy in developing countries typically examine either the distribution of tax burdens or the incidence of public expenditures. But the central issue for policymakers is the combined or net incidence of fiscal activities. One reason that combined incidence studies are so rare is that they require detailed data on both taxation and public spending. The authors show that the net incidence of fiscal policy in a country with average data - the Philippines - can be estimated using a variety of data sources and tools, using simplifying assumptions. For 20 years, the Philippine economy has experienced a series of balance of payments crises triggered by fiscal crises. It has had an unsatisfactory record of poverty alleviation. The authors examine net fiscal incidence to find out how poverty will be affected by the rise in taxes and the cut in spending. They found that: 1) the incidence pattern of taxes is basically neutral. Contrary to expectations, indirect taxes are only slightly regressive; and 2) it is the pattern of expenditures that drives the combined incidence, which is progressive.Public Sector Economics&Finance,Environmental Economics&Policies,Health Systems Development&Reform,Economic Theory&Research,Health Economics&Finance,Environmental Economics&Policies,Public Sector Economics&Finance,Economic Theory&Research,Health Economics&Finance,Banks&Banking Reform

Biochar for horticultural and agricultural applications using high temperature torrefaction technology: Biochar for horticultural and agricultural applications using high temperature torrefaction technology
No full textBiochar for horticultural and agricultural applications using high temperature torrefaction technology Pradeep Ravi Supervisors: Prof Dr. D.J.E.M Roekaerts, ir.Bart de Vries, Dr. Luis Cutz, Dr.Lorenzo Botto & Dr.Ralph Lindeboom Biomass currently accounts for less than 10 percentage of the world’s renewable energy production. Currently the major global sustainability issue stems from the sourcing of virgin wood chips from dense forests for pellet production. An alternative is to use residual biomass from agriculture or forestry, which is produced in large volumes, to produce different products that range from biofuels to chemicals via thermochemical conversion technologies. Among thermochemical technologies, torrefaction is a promising route to produce solid biofuel known as biochar. With an increasing potential for biomass production coupled with an increased scrutiny on the use of biomass as a green fuel, the need for alternative clean applications for the biochar is critical. The aim of this study is to investigate new and novel agricultural residues or other waste streams to produce biochar using high temperature (350 °C) torrefaction technology. The obtained biochar is evaluated experimentally to determine the best feedstocks out of the ones that are selected from a performance and cost point of view for horticultural applications. . This research aims to provide a clear and useful analytical tool which will benefit the scientific community to select suitable biomass materials based on material properties and end applications. The efficacy for the various torrefied biomass feedstocks on the soil and its stability are tested. Overall, about 50 different biomass feedstocks were identified and evaluated based on past performances from literature. The top 10 best performing feedstocks were sourced and subjected to various physical and chemical characterization tests with a specific focus on soil remediation. The selected materials were torrefied in a fixed bed pilot reactor Scanning Electron Microscopy with Energy Dispersive X-Ray Spectroscopy (SEM-EDS), Brunauer–Emmett–Teller (BET) and pH measurements. Ultimately the feedstocks were scored and ranked from best to worst performing biochar for soil remediation and sequestration-based applications. The results of this project indicate potential for biochar production from woody, grassy and other processed materials that could help to remove the dependence on evergreen forests and wood chips. The system proposed in this work could also yield negative emissions since the feedstocks are residual flows and the biochar is going to be used in the soil.Electrical Engineering | Sustainable Energy Technolog

No full textOn Providing Support For Protocol Adaptation in Mobile Wireless Networks
No full textThe availability of a variety of communication devices o ers a choice among networks with vastly di erent characteristics. A mobile host is likely to encounter these di erent networks and no single protocol or application can be expected to perform well under all these networks. The problem of adapting to a changing network environment is further complicated by the fact that changes in network conditions are usually transparent to the applications. In order to allow automatic adaptation of applications and protocols, awareness of link conditions and network environment is required. In this paper we present a uniform mechanism based on ICMP messages for providing environmental information to all the network protocol layers. We also show how applications and protocols can adapt to changes in the environment and in particular, demonstrate dynamic ne tuning of some of the well known protocols such as UDP and TCP. Performance measurements demonstrate that our mechanism imposes very little overhead and results in better performance of protocols that can adapt to changing network conditions.Technical report DCS-TR-33
Talking Trucks: Decentralized Collaborative Multi-Agent Order Scheduling for Self-Organizing Logistics
No full textLogistics planning is a complex optimization problem involving multiple decision makers. Automated scheduling systems offer support to human planners; however state-of-the-art approaches often employ a centralized control paradigm. While these approaches have shown great value, their application is hindered in dynamic settings with no central authority. Motivated by real-world scenarios, we present a decentralized approach to collaborative multi-agent scheduling by casting the problem as a Distributed Constraint Optimization Problem (DCOP). Our model-based heuristic approach uses message passing with a novel pruning technique to allow agents to cooperate on mutual agreement, leading to a near-optimal solution while offering low computational costs and flexibility in case of disruptions. Performance is evaluated in three real-world field trials with a logistics carrier and compared against a centralized model-free Deep Q-Network (DQN)-based Reinforcement Learning (RL) approach, a Mixed-Integer Linear Programming (MILP)-based solver, and both human and heuristic baselines. The results demonstrate that it is feasible to have virtual agents make autonomous decisions using our DCOP method, leading to an efficient distributed solution. To facilitate further research in Self-Organizing Logistics (SOL), we provide a novel real-life dataset.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Algorithmic
