Maximizing social welfare among EF1 allocations at the presence of two types of agents
We study the fair allocation of indivisible items to $n$ agents to maximize the utilitarian social welfare, where the fairness criterion is envy-free up to one item and there are only two different utility functions shared by the agents. We present a $2$-approximation algorithm when the two utility functions are normalized, improving the previous best ratio of $16 \sqrt{n}$ shown for general normalized utility functions; thus this constant ratio approximation algorithm confirms the APX-complete…

“For hours I was in their custody – phone and all devices confiscated, very rude bullying interrogation, threatening me with jail time. After (a) couple hours of this, they ultimately ordered to send me back home to Prague,” Skuta wrote.

Maximizing Social Welfare with Side Payments
We examine normal-form games in which players may \emph{pre-commit} to outcome-contingent transfers before choosing their actions. In the one-shot version of this model, Jackson and Wilkie showed that side contracting can backfire: even a game with a Pareto-optimal Nash equilibrium can devolve into inefficient equilibria once unbounded, simultaneous commitments are allowed. The root cause is a prisoner's dilemma effect, where each player can exploit her commitment power to reshape the equilibri…

To go back to my previous post, for a plant-based diet to be attractive, we need to help people choose plant based alternatives to meat for more or less all occasions. So meat is no longer the default
That's what we need good chefs for: to help turn traditional foods into vegetarian/vegan alternatives that are tasty and easy to prepare.
Most traditional dishes are surprisingly modern. Our tastes can easily be changed...
As an example, in France, the markets are laden with charcuterie and cheese, BUT ALSO, beautiful fresh fruits and vegetables - a nudge towards the latter would improve human health, animal welfare and reduce emissions...

The Ejecta Nebula Around the Wolf-Rayet Star WR 71: #WolfRayet star WR~71 (HD 143414). [...] Deep H and [O III] images like those presented here suggests that new and substantially deeper imaging reconnaissance of WR star nebulae compared to earlier surveys may lead to additional WR ring nebula detections, thereby enhancing our understanding on the frequency and formation of WR ring nebulae."

Auch im DLF wird die rechtsaußen-Vokabel 'Gendersprache' inzwischen ohne Einordnung benutzt.
"Immer wieder wird in Deutschland zum Teil kontrovers über die Gendersprache diskutiert."
Die deutsche Grammatik macht es unmöglich, nicht zu gendern. (Die.. Grammatik..)
Gemeint ist etwas anderes: Die Anpassung der deutschen Sprache an die Realität, dass in weiten Teilen der Gesellschaft angekommen ist, dass Männer nicht die Norm sind.

Detecting and measuring respiratory events in horses during exercise with a microphone: deep learning vs. standard signal processing

Detecting and measuring respiratory events in horses during exercise with a microphone: deep learning vs. standard signal processing
Monitoring respiration parameters such as respiratory rate could be beneficial to understand the impact of training on equine health and performance and ultimately improve equine welfare. In this work, we compare deep learning-based methods to an adapted signal processing method to automatically detect cyclic respiratory events and extract the dynamic respiratory rate from microphone recordings during high intensity exercise in Standardbred trotters. Our deep learning models are able to detect …

Design of a three-dimensional parallel-to-point imaging system based on inverse methods
We present an inverse method for designing a three-dimensional imaging system comprising of freeform optical surfaces. We impose an imaging condition on the optical map and combine it with the law of conservation of energy to conclude that the ratio of energy distributions at the source and target of an imaging system must be constant. A mathematical model for the design of a parallel-to-point system consisting of two freeform reflectors is presented. A Schwarzschild telescope, a classical desi…
