Benchmarking Marl On Long Horizon Sequential Multi-Objective Tasks, Minghong Geng, Shubham Pateria, Budhitama Subagdja, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

Current MARL benchmarks fall short in simulating realistic scenarios, particularly those involving long action sequences with sequential tasks and multiple conflicting objectives. Addressing this gap, we introduce Multi-Objective SMAC (MOSMAC), a novel MARL benchmark tailored to assess MARL methods on tasks with varying time horizons and multiple objectives. Each MOSMAC task contains one or multiple sequential subtasks. Agents are required to simultaneously balance between two objectives - combat and navigation - to successfully complete each subtask. Our evaluation of nine state-of-the-art MARL algorithms reveals that MOSMAC presents substantial challenges to many state-of-the-art MARL methods and effectively fills a critical gap …

California And Europe Require Scope 3 Climate Disclosures Despite Sec Retreat, Michael B. Gerrard

Faculty Scholarship

In March 2022, the U.S. Securities and Exchange Commission (SEC) issued proposed regulations on disclosure of climate-related information by public companies, including their material Scope 3 greenhouse gas (GHG) emissions. This created a firestorm, drawing more than 24,000 comment letters.On March 6, 2024, the SEC issued its final rule, significantly narrowing the requirements and, notably, eliminating the Scope 3 disclosures. Companies that do not want to make Scope 3 disclosures should not rejoice and environmental advocates and others who do want to see such disclosures should not despair, because new requirements from both California and Europe do mandate this information …

Bail At The Founding, Kellen R. Funk, Sandra G. Mayson

Faculty Scholarship

How did criminal bail work in the Founding era? This question has become pressing as bail, and bail reform, have attracted increasing attention, in part because history is thought to bear on the meaning of bail-related constitutional provisions. To date, however, there has been no thorough account of bail at the Founding. This Article begins to correct the deficit in our collective memory by describing bail law and practice in the Founding era, from approximately 1790 to 1810. In order to give a full account, we surveyed a wide range of materials, including Founding-era statutes, case law, legal treatises, and …

The Role Of Extracellular Vesicles In Immunomodulation During Bovine Pregnancy, Amber E. Thornton

All Graduate Theses and Dissertations, Fall 2023 to Present

During pregnancy, the maternal immune system must be altered to protect the partially non-self fetus from attack. Our previous studies show an inflammatory response in the uterus of cows carrying somatic cell nuclear transfer (SCNT), commonly known as cloned, pregnancies due to abnormalities in proteins expressed by placental trophoblast cells. Between 30 and 90 days the rate of pregnancy loss is 50-100% for SCNT compared to 2-10% for artificial insemination (AI) pregnancies. Abnormal communication between the maternal and fetal systems during placentation is a major cause of this loss. The trafficking of extracellular vesicles (EVs), membrane-bound cargo carriers, potentially represents …

Introduction Extracorporeal membrane oxygenation (ECMO) is associated with a high rate of neurologic complications. Multimodal neurologic monitoring (MNM) has the potential for early detection and intervention. We examined the safety and feasibility of noninvasive MNM during ECMO. We hypothesized that survivors and non-survivors would have meaningful differences in transcranial Doppler (TCD) sonography and electroencephalographic (EEG) characteristics, which we aimed to identify. We also investigated adverse neurologic events and attempted to identify differences in EEG and TCD characteristics among patients based on the type of ECMO and the occurrence of these events. Material and methods We performed an observational study on …
