In this work, we improve the reliability of agent behaviors by closed-loop fine-tuning of behavior models with reinforcement learning. Our method demonstrates improved overall performance, as well as targeted metrics such as collision rate, on the Waymo Open Sim Agents challenge. Additionally, we ...
Prior to the injection of the contrast agent, a sequence was scanned during diastole using prospective gated acquisition. This non-contrast sequence was used to extract the CAC scores, which were automatically calculated by the software and confirmed manually. The segmentation of PVAT was performed...
RL is commonly viewed as a problem where an intelligent agent learns from its trial-and-error interactions with an uncertain environment. An interaction can be described as a discounted Markov Decision Process (MDP) in the form \(\langle S,A,P,R, \gamma \rangle \) [13], where \(\gamma...
Another aspect to consider is the potential influence of conducting an audit on providers’ prescribing behaviors. The HCPs are aware of being observed, which can lead to what is known as the Hawthorne effect. It is important to note that this study is not a clinical trial and lacks a ...
Instead of explicitly modelling behaviors like cruising, dispatching, and matching, these studies directly learn from agent interactions in simulation environments (Peng et al., 2021). Verma et al. (2017) based their formulation of taxi cruising problem on an activity graph and learned value ...
approaches to optimize physicochemical properties of DDSs as well as considering specific cancer cell receptors in the TME, which are two critical parameters that could significantly impact on drug delivery performance [20]. In this study, we used SPION as an MRI contrast agent within the MSN to...
In the present work, we used a small mole fractions (5 wt.%) of metallic glassy of Zr70Ni20Pd10 powders as a new enhancement agent to improve its hydrogenation/dehydrogenation behaviors of MgH2. This short- range ordered material led to lower the decomposition temperature of MgH2 and its ...
As an important case example of the range of candidate drugs that could fit into a new anti-maladaptive aggression agent category, we will review an investigational IA pharmacotherapy. SPN-810 (extended-release molindone) is currently being investigated as a novel treatment for children with IA ...
Li et al. on the other hand, used the electrostatic interaction between mulberry leaf polysaccharides and lysozyme to construct self-assembled micelles loaded with luteolin for the treatment of liver lipid accumulation [45]. These self-assembly behaviors not only improve the stability and ...
However, its flexural strength decreases even in the presence of a compatibilizing agent. This reduction in flexural strength can be attributed to poor matrix/reinforcement anchoring. Although the deleterious effect of excess SMA in PS-based composites is well-known, it is more likely that in ...
