We analyze reinforcement learning under so-called "dynamic reinforcement." In reinforcement learning, each agent repeatedly interacts with an unknown environment (i.e., other agents), receives a reward, and updates the probabilities of its next action based on its own previous actions and received rewards. Unlike standard reinforcement learning, dynamic reinforcement uses a combination of long-ter
The aim of this study was to investigate the association between smoking and bone mineral density (BMD) and radiographically verified prevalent vertebral fractures and incident fractures in elderly men. At baseline 3003 men aged 69 to 80 years of age from the Swedish Mr Os Study completed a standard questionnaire concerning smoking habits and had BMD of the hip and spine measured using dual-energy
The phenomenon of adopting open source software development practices in a corporate environment is known by many names, one being inner source. The objective of this study is to investigate how an organization consisting of small development teams can benet from adopting inner source and assess the level of applicability. The research has been conducted as a case study at a software development c
The increasing number of new psychoactive substances made available for recreational drug use has created a challenge for clinical toxicology and drug testing laboratories. As a consequence, the routine immunoassay drug testing may become less effective due to an increased occurrence of false negative and false positive screening results. This work aimed to extend the knowledge about analytical cr
Nowadays, the same piece of code should run on different architectures, providing performance guarantees in a variety of environments and situations. To this end, designers often integrate existing systems with ad-hoc adaptive strategies able to tune specific parameters that impact performance or energy—for example, frequency scaling. However, these strategies interfere with one another and unpred
Stochastic optimal power flow can provide the system operator with adequate strategies for controlling the power flow to maintain secure operation under stochastic parameter variations. One limitation of stochastic optimal power flow has been that only steady-state variable limits have been used as security constraints. In many systems voltage stability and small-signal stability also play an impo
Forskningsprojektet Urban Nature undersöker möjligheten att möta olika urbana utmaningar med naturbaserade lösningar. Vad är naturbaserade lösningar? Naturbaserade lösningar är lösningar som är inspirerade eller stöds av naturen. Med naturbaserade lösningar finns möjligheten att möta urbana utmaningar, som den globala klimatförändringen, på ett hållbart sätt samtidigt som lösningarna bidrar till e

We present a generic way to obtain level lower bounds for (promise) CSP hierarchies from degree lower bounds for algebraic proof systems. More specifically, we show that pseudo-reduction operators in the sense of Alekhnovich and Razborov [Proc. Steklov Inst. Math. 2003] can be used to fool the cohomological k-consistency algorithm. As applications, we prove optimal level lower bounds for c vs. ℓ-c
The impoundment of hydroelectric reservoirs is associated with significant emissions of green house gases. In addition, the loss of the pre-flooded landscape is a substantial factor in the long-term carbon footprint of hydroelectric reservoirs. The Paix-des-Braves reservoir in Québec was one of the first reservoirs to be studied in regards of its total carbon footprint, combining pre- and post-imp
Biodiversity hotspots are biogeographic regions exceptionally rich in endemic species showing high rates of habitat loss, making them the priority of global conservation efforts. As part of the biodiversity hotspot with the highest density of endemic species, the West Usambara Mountains in Tanzania require an efficient and resourceful monitoring solution. This thesis aimed to model the tree specie
Forest Aboveground biomass (AGB) is an important indicator of forest carbon storage, but long-term, high-resolution, and spatially continuous Aboveground biomass estimation remains challenging. This study produced annual forest Aboveground biomass estimates across mainland Spain and the Balearic Islands from 2000 to 2024 at 30 m resolution by combining Landsat time series, Global Ecosystem Dynamic
Renewable energy expansion and carbon sink enhancement are central to developing sustainable climate pathways, yet the rapid deployment of renewable energy technologies is intensifying land-use competition and increasing the need for more resource-efficient siting strategies. Solar development on former peat extraction sites represents one such approach, as it enables the use of degraded land whil
Atserias and Müller (JACM, 2020) proved that for every unsatisfiable CNF formula ℓ, the formula Ref(ℓ) stating that 'ℓ has small Resolution refutations"-does not have subexponential-size Resolution refutations. Conversely, when ℓ is satisfiable, Pudlák (TCS, 2003) showed how to construct a polynomial-size Resolution refutation of REF(ℓ) given a satisfying assignment of ℓ. A question that had remai
We present a simple method based on a variant of Hölder’s inequality to lower-bound the trace norm of Boolean matrices. As the main result, we obtain an exponential separation between the randomized decision tree depth and the spectral norm (i.e. the Fourier L1-norm) of a Boolean function. This answers an open question of Cheung, Hatami, Hosseini, and Shirley (CCC 2023). As immediate consequences,
