Association of Computing Machinery Open Access Agreement Publications-Archive

We present a comprehensive and in-depth study of Intel Optane DC persistent memory (DCPMM). Our focus is on exploring the internal design of Optane’s on-DIMM readwrite buffering and its impacts on application-perceived performance, read and write amplifications, the overhead of different types of persists, and the tradeoffs between persistency models. While our measurements confirm the results of the existing profiling studies, we have new discoveries and offer new insights. Notably, we find that read and write are managed differently in separate on-DIMM read and write buffers. Comparable in size, the two buffers serve distinct purposes. The read buffer offers higher …

The bromination of poly(isobutylene-co-isoprene) rubber introduces a small amount of bromide groups (1–2 mol%) to the elastomer backbone and creates new opportunities for functionalisation, as compared to other saturated and diene elastomers. In this work, three types of nucleophile reagents: namely pyridine, triphenylphosphine and imidazoles bearing four types of side groups of methyl, ethyl, hydroxyl or vinyl group were introduced to brominated poly(isobutylene-co-isoprene) rubber (BIIR) through nucleophile substitution with the bromine via solid-state rubber compounding and curing processes. The resulted ionic aggregates act as physical crosslinks and their size and density directly affected the mechanical reinforcement, self-healing and dynamic mechanical …


Mönckeberg Sclerosis With Giant Cells As A Masquerade Of Giant Cell Arteritis, Andrew Johannemann, A D. Proia, Lisa Criscione-Schreiber Apr 2022

Mönckeberg Sclerosis With Giant Cells As A Masquerade Of Giant Cell Arteritis, Andrew Johannemann, A D. Proia, Lisa Criscione-Schreiber

Osteopathic Medicine, Jerry M. Wallace School of

Giant cell arteritis (GCA) is the most common type of vasculitis in adults, which is classified as a large/medium vessel vasculitis. It has a predilection for the ophthalmic circulation and extracranial carotid system. Temporal artery biopsy specimens can show the presence of inflammatory multinucleated giant cells. Here, we report just the third case of Mönckeberg sclerosis with multinucleated giant cells affecting the temporal artery and mimicking GCA. This rare finding in the evaluation of a common vasculitis is important for rheumatologists to be aware of and emphasizes close collaboration between clinicians and pathologists.

Osteopathic Medicine, Jerry M. Wallace School of

Lipopolysaccharide (LPS), also known as endotoxin, can trigger septic shock, a severe form of inflammation-mediated sepsis with a very high mortality rate. However, the precise mechanisms underlying this endotoxin remain to be defined and detoxification of LPS is yet to be established. Macrophages, a type of immune cells, initiate a key response responsible for the cascade of events leading to the surge in inflammatory cytokines and immunopathology of septic shock. This study was undertaken to determine whether the LPS-induced inflammation in macrophage cells could be ameliorated via CDDO-IM (2-cyano-3,12 dioxooleana-1,9 dien-28-oyl imidazoline), a novel triterpenoid compound. Data from this study …

Increasing Accessibility Of Language Models With Multi-Stage Information Extraction, Conrad Czejdo, Sambit Bhattacharya

College of Health, Science, and Technology

The capabilities of Language Models (LMs) have continued to increase in recent years, as have their computational requirements. Widely available APIs have also become available. These APIs present new challenges for ease of gradient based fine-tuning by users, resulting in the use models which may be larger than necessary and more expensive, therefore reducing accessibility. In this paper, we present a new methodology for increasing performance of single-shot LMs by chaining multiple smaller LMs. Additionally, as the derived representation is in plain-text it is readily human interpretable. We show that optimizing the context which leads to this derived representation results …
