Transforming cumulative hazard estimates

Mats Julius Stensrud, Pal Christie Ryalen

Time-to-event outcomes are often evaluated on the hazard scale, but interpreting hazards may be difficult. Recently in the causal inference literature concerns have been raised that hazards actually have a built-in selection bias that prevents simple causa ...

Selection Bias in News Coverage: Learning it, Fighting it

Karl Aberer, Jérémie Rappaz

News entities must select and filter the coverage they broadcast through their respective channels since the set of world events is too large to be treated exhaustively. The subjective nature of this filtering induces biases due to, among other things, res ...

Reducing false positives in tractography with microstructural and anatomical priors

Jean-Philippe Thiran, Gabriel Girard, Alessandro Daducci, Muhamed Barakovic, Maxime Descoteaux

Tractography has proven particularly effective for studying noninvasively the neuronal architecture of the brain but recent studies have showed that the high incidence of false positives can significantly bias any connectivity analysis. We present a novel ...

The STM bias voltage-dependent polymorphism of a binary supramolecular network

Klaus Kern, Magalí Alejandra Lingenfelder, Fernando Pablo Cometto, Bart Willem Stel, Kilian Frank

A Scanning Tunneling Microscope (STM) is used to induce a reversible transition between different polymorphs in a binary supramolecular network at the liquid/solid interface. The transition is driven externally by switching the polarity of the sample by po ...

No money, no honey? Financial versus knowledge and demand constraints on innovation

Gabriele Pellegrino

The paper adds to the literature on the barriers to innovation in two ways. First, we assess comparatively what mostly constrains firms' ability to translate investment in innovation activity into new products and processes, whether it is mainly finance, a ...

A start-up boosting circuit with 133× speed gain for 2-transistor voltage reference

Kyojin Choo

This work presents a start-up boosting circuit designed for fast stabilization of a 2-transistor voltage reference. A clock injection method is used to induce a large bias on the 2-transistor voltage reference resulting in a fast output voltage settling wh ...

Structural estimation for route choice models considering link specificity of measurement error variances

Yuki Oyama

For estimating parameters of discrete choice models, observations corresponding to the models are required. In the context of route choice models, we need the information of paths, which are sequences of links and connect between the origin-destination pa ...

Heading for new shores! Overcoming pitfalls in BCI design

Ricardo Andres Chavarriaga Lozano

Research in brain-computer interfaces has achieved impressive progress towards implementing assistive technologies for restoration or substitution of lost motor capabilities, as well as supporting technologies for able-bodied subjects. Notwithstanding this ...

Strong paramagnon scattering in single atom Pd contacts

Klaus Kern, Markus Ternes, Uta Schlickum, Peter Wahl, Ivan Pentegov, Verena Katharina Schendel

Among all transition metals, palladium (Pd) has the highest density of states at the Fermi energy at low temperatures yet does not fulfill the Stoner criterion for ferromagnetism. However, close proximity to magnetism renders it a nearly ferromagnetic meta ...

Quantifying the Bullwhip Effect Using Two-Echelon Data: A Cross-Industry Empirical Investigation

Ralf Seifert, Olov Isaksson

The bullwhip effect denotes the phenomenon whereby demand variability is amplified from a downstream site (buyer) to an upstream site (supplier) in the supply chain. This paper contributes to the literature that empirically investigates the bullwhip effect ...
