Attempts to implement CRISPR/Cas9 for genome editing in the oomycete Phytophthora infestans
(2018)bioRxivFew techniques have revolutionized the molecular biology field as much as genome editing using CRISPR/Cas9. Recently, a CRISPR/Cas9 system has been developed for Phytophthora sojae, and since then it has been employed in two other Phytophthora spp. Here, we report our progress on efforts to establish the system in Phytophthora infestans. Using the original constructs as developed for P. sojae, we did not obtain any transformants displaying ...Working Paper -

A formal analysis of 5G authentication
(2018)arXivMobile communication networks connect much of the world's population. The security of users' calls, SMSs, and mobile data depends on the guarantees provided by the Authenticated Key Exchange protocols used. For the next-generation network (5G), the 3GPP group has standardized the 5G AKA protocol for this purpose. We provide the first comprehensive formal model of a protocol from the AKA family: 5G AKA. We also extract precise requirements ...Working Paper -
Does variation in residents’ spatial mobility affect their preferences concerning local governance?
(2018)Arbeitsberichte Verkehrs- und RaumplanungThe geographic scope of people’s mobility behaviour has generally been increasing over recent decades. Yet, many policies continue to be enacted and implemented at the local level (e.g. in municipalities), leading to a mismatch in geographical scope. Our research thus speaks to a debate over two contradictory arguments. First, residents’ increased spatial mobility has led to a mismatch between what residents want in terms of governance ...Working Paper -
The Value of Communication in Designing Robust Distributed Controllers
(2018)We consider computation of optimal distributed controllers with constraints on states and inputs. The problem of distributed control arises in several large-scale systems, such as transportation networks and power grid systems. Well-established results highlight the intractability of the corresponding optimization problem for many cases of interest. In particular, convex computation of controllers having a fixed sparsity pattern is not ...Working Paper -

Comparing values of travel time obtained from residential, workplace and short-term decisions
(2018)Arbeitsberichte Verkehrs- und RaumplanungThe value of travel time (VTT) is an important element cost-benefit analysis of transportation projects, by encapsulating the willingness to pay of the population for improvements in the transport system. Those values are typically obtained from mobility behaviour data, in form of revealed or stated preference survey data. Although short-term decisions are typically used for this purpose, a growing number of authors is arguing that long-term ...Working Paper -
The German value of time (VOT) and value of reliability (VOR) study
(2018)Arbeitsberichte Verkehrs- und RaumplanungIn 2012 Germany’s Federal Ministry of Transport and Digital Infrastructure (BMVI) initiated several projects in preparation of the new Federal Transport Investment Plan (BVWP) 2030. This included an update of the general methodology and in particular of its cost-benefit analysis (CBA) which is used to evaluate the effects of hundreds of German infrastructure projects under study. As part of the work the first official values of time (VOT) ...Working Paper -
Studying cyclists’ behavior in a non-naturalistic experiment utilizing cycling simulator with immersive virtual reality
(2018)Arbeitsberichte Verkehrs- und RaumplanungThis study investigates the combination immersive virtual reality (VR) and an instrumented cycling simulator for in-depth behavioral studies of cyclists. To this end, a cycling simulator was developed, virtual environments resembling Singapore were created, combined with the output of a traffic microsimulation. This set-up was created with the specific objective of evaluating the effects environment properties and road infrastructure ...Working Paper -
Multi-modal route choice modeling in a dynamic schedule-based transit network
(2018)Route choice behavior has predominantly been analyzed from the angle of a single mode, most often the car. Considering route choice in the broader context of multi- modal networks yet opens the way to more complex policy analysis and wider applications. The main modeling challenges in this context are the limited availability in time of public transport services and the definition of alternatives to the observed path. This paper tackles ...Working Paper -
The social aspect of residential location choice
(2018)Arbeitsberichte Verkehrs- und RaumplanungCommuting has been found to be one of the least enjoyable activities. As it is a consequence of the choice of home and work location, the question arises as to how its disutility is compensated. Urban location theory suggests a compensation in the housing or the labor market. While this provides part of the explanation, individuals’ personal networks may provide additional insights. Data from a social network survey were used to investigate ...Working Paper -

Modelling intermodal travel in Switzerland
(2018)Arbeitsberichte Verkehrs- und RaumplanungWe use data from the Swiss national household travel survey to 1. analyse the socioeconomic determinants for intermodal travel in Switzerland and 2. estimate a first large-scale multimodal recursive logit route choice model for urban trip making. We show that intermodal travel is mostly associated with ownership of transit subscriptions, which allow free at the point-of-use public transportation. We also present a framework using open-source ...Working Paper -

Assessing the welfare impacts of shared mobility and Mobility as a Service (MaaS)
(2018)Arbeitsberichte Verkehrs- und RaumplanungMobility as a Service (MaaS) aims to allow less biased mode choice decisions by overcoming market segmentation. To this end, all available modes are offered at their respective marginal cost for each trip. Such a setting favors shared modes, where fixed costs can be apportioned among a large number of users. In turn, car-sharing, bike-sharing or ride- hailing may themselves become an efficient alternative of public transport. Although ...Working Paper -
Privacy Loss Classes: The Central Limit Theorem in Differential Privacy
(2018)In recent years, privacy enhancing technologies have gained tremendous momentum and they are expected to keep a sustained importance. Quantifying the degree of privacy offered by any mechanism working on potentially sensitive data is a complex and well-researched topic; epsilon-differential privacy (DP) and its slightly weaker and more versatile variant (epsilon,delta)-approximate differential privacy (ADP) have become the de-facto standard ...Working Paper -

Bicycling accessibility based on dock-less bicycle-sharing data
(2018)Arbeitsberichte Verkehrs- und RaumplanungAccessibility for non-motorized traffic is an important topic in the transportation. To obtain the measures of bicycle accessibility, we estimated the impedance function for different purposes using the Shanghai dock-less bicycle-sharing data. In specific, as the bicycling data have no trip purpose information, the information was imputed by a Dirichlet-multinomial regression topic model (DMR), which could consider the arriving time and ...Working Paper -
Krylov and Modal Subspace based Model Order Reduction with A-Priori Error Estimation
(2018)Versatile model order reduction techniques for the reduction of dynamic systems have been presented in the last decades. Krylov subspace based methods are considered as efficient in terms of computational effort and reduction order and can be used in order to match the transfer function locally. However, they lack of a simple and efficient automatisation and error estimation. On the other hand, modal reduction is popular because it leads ...Working Paper
