1. Multi Agent Reinforcement Learning for Karma Economies 

   Vaishampayan, Saurabh (2024)

   Recently, new class of dynamic resource allocation mechanisms, called karma mechanisms, have shown great promise in acheiving fair and efficient outcomes. The analysis of karma mechanisms relies on the availability of versatile computational tools to predict the Nash equilibrium of a "karma game". Existing algorithms used to compute Nash equilibria of a karma game are centralized in nature, severely limiting the size and complexity of ...

2. On Automatic Person-in-Water Detection for Marine Search and Rescue Operations 

   Taipalmaa, Jussi; Raitoharju, Jenni; Queralta, Jorge Pena; et al. (2024)

   IEEE Access

   In marine search and rescue missions, the objective is to find a missing person in the water. Time is a critical factor in the identification of the missing person, as any delay in locating them can have life-threatening consequences. Autonomous unmanned aerial vehicles (UAVs) possess the potential to help in the search task by providing a bird's-eye view helping to cover larger areas faster. Therefore, it is very important that UAVs can ...

3. Modeling the morphological response of gravel-bed rivers subject to repeated sediment bypass tunnel operations 

   Facchini, Matteo; Vetsch, David F.; Boes, Robert M.; et al. (2024)

   FRONTIERS IN EARTH SCIENCE

   Introduction: Sediment bypass tunnels (SBTs) are operated during floods to re-establish sediment continuity past dams with the ultimate goal of decreasing accumulation in reservoirs. Depending on the location of the intake structure and operational conditions, SBTs may release either bed load-laden or bed load-free flows in the form of sudden floods (pulses). When evaluating the impacts of SBTs, the traditional approach has been to monitor ...

4. Evidence for an RNAi-independent role of Arabidopsis DICER-LIKE2 in growth inhibition and basal antiviral resistance 

   Nielsen, Carsten Poul Skou; Arribas-Hernandez, Laura; Han, Lijuan; et al. (2024)

   The Plant Cell

   Flowering plant genomes encode four or five DICER-LIKE (DCL) enzymes that produce small interfering RNAs (siRNAs) and microRNAs, which function in RNA interference (RNAi). Different RNAi pathways in plants effect transposon silencing, antiviral defense, and endogenous gene regulation. DCL2 acts genetically redundantly with DCL4 to confer basal antiviral defense. However, DCL2 may also counteract DCL4 since knockout of DCL4 causes growth ...

5. Functional graded NiTi manufactured with powder bed fusion 

   Weber, Rico; Tosoratti, Enrico; Spierings, Adriaan B.; et al. (2024)

   Progress in Additive Manufacturing

   Nickel-titanium (NiTi) is a versatile material with unique inherent properties, such as shape recovery, superelasticity, and biocompatibility, that makes it suitable for various engineering applications. While NiTi can be additively manufactured using powder bed fusion for metals (PBF-LB/M), challenges arise due to the material sensitivity to process parameters and the challenge of achieving desired mechanical and functional properties. ...
