Currently, scientific knowledge faces challenges including coordinated misinformation campaigns and the erosion of institutional trust. Information distortion heavily impacts public discourse on global development and governance. Join us for a compelling discussion on the challenges misinformation poses to science, including:The role of social media algorithms and their corresponding digital ecosystems in amplifying false narratives.The impact of politicized scientific communication on sectors such as public health (e.g., the COVID pandemic) and environmental policy (e.g., the ongoing effects of climate change).Practical strategies for rebuilding trust between scientific communities and the public.Speakers:Mariana Díaz García, Associate Programme Officer at the United Nations Interregional Crime and Justice Research Institute (UNICRI)Joan Donovan, Assistant Professor of Journalism and Emerging Media Studies at Boston UniversityChristopher Reddy, Senior Scientist at Woods Hole Oceanographic Institution (WHOI)Moderator:Jana M.

Speaker: Arka Adhikari (University of Maryland)Title: MODERATE DEVIATIONS FOR THE CAPACITY OF THE RANDOM WALK RANGE IN DIMENSION FOURAbstract:We find a natural four dimensional analog of the moderate deviation results for the capacity of the random walk, which corresponds to Bass, Chen and Rosen concerning the volume of the random walk range for d = 2. We find that the deviation statistics of the capacity of the random walk can be related to the following constant of generalized Gagliardo-Nirenberg inequalities, \begin{equation*} \inf_{f: \| abla f\|_{L^2}<\infty} \frac{\|f\|^{1/2}_{L^2} \| abla f\|^{1/2}_{L^2}}{ [\int_{(\mathbb{R}^4)^2} f^2(x) G(x-y) f^2(y) \text{d}x \text{d}y]^{1/4}}. \end{equation*}--Note: Back-to-back seminars with different times.
