Weighing the impacts of our goods and services on the environment and climate: how to measure?
The car we buy is made out of thousands of components, which are produced using different types of materials. These materials need to be sourced from different places, sent to production facilities and assembled. Once the car is dismissed, the components need to be taken care of by either reusing, recycling…

Decompositions in algebra
We show that Kirchhoff ’s law of conservation holds for non-commutative graph flows if and only if the graph is planar. We generalize the theory of (Euclidean) lattices to infinite dimension and consider the ring of algebraic integers as such a lattice.

Was the EU’s ban on electric fishing the right decision?
Last week, on 13 February 2019, the EU approved the ban on pulse trawling. This followed the vote for a ban by the European Parliament on 16 January 2018. Half of the 84 Dutch pulse trawling vessels must stop immediately; the other half will receive a transitional arrangement until July 2021. Outcomes…

Tim van Erven makes computers even smarter
In high school, Tim van Erven read about an artificially intelligent algorithm that could solve mazes. From that moment on, he was sold: ‘There’s something magical about algorithms. With a list of fixed rules you can make them learn the most diverse things.’ This year, he won a Vidi grant, which he…

The psychological poverty trap: How lack of money impacts decision-making, procrastination and loss of control
Lack of money impacts how a person takes financial decisions: now or preferably later. Procrastination and avoidance behaviours in turn have an effect on lack of money, which can result in a sense of loss of control. These are the findings of psychologist Leon Hilbert in his PhD research, although the…

eLaw publishes article in Computer Law & Security Review
In healthcare, gender and sex considerations are crucial because they affect individuals' health and disease differences. Yet, most algorithms deployed in the healthcare context lack close consideration of these aspects and do not account for bias detection. In their latest paper, Eduard Fosch-Villaronga,…

The widow, the neighbour and the pump in the garden pond: how court decisions could respond better to society
People come to court because of a legal dispute, and often think that the court decision will also resolve the underlying conflict. But that is not always the case. ‘Court decisions should provide a better response to the needs and the nature of citizens,’ argues professor by special appointment Rogier…

New scanning method turns objects inside out at high speed
What if you could watch a CT scan live, instead of analysing the images afterwards? If it is up to the Leiden mathematician Jan-Willem Buurlage, that will soon be a reality. He is developing methods to make the algorithms behind 3D scans faster. Quite a challenge: ‘Just like mathematicians, computers…

The search for a ‘quantum advantage’
Proving a quantum computer to be quicker than a normal one is one step closer. After a breakthrough in speeding up classical algorithms, researchers Vedran Dunjko and Casper Gyurik showed that only one quantum algorithm could beat its classical counterpart. They discuss their discovery in Quanta Mag…

The use of Deep Learning in the automated detection of archaeological objects in remotely sensed data
Generally the data from remote sensing surveys - the scanning of the earth by satellite or aircraft in order to obtain information about it - is screened manually in archaeology. However, constant monitoring of the earth's surface causes a huge influx of data of high complexity and high quality. To…
