Multi-Link Prediction For Mmwave Wireless Communication Systems Using Liquid Time-Constant Networks, Long Short- Term Memory, And Interpretation Using Symbolic Regression, Vishnu S. Pendyala, Milind Patil

Faculty Research, Scholarly, and Creative Activity

A significant challenge encountered in mmWave and sub-terahertz systems used in 5G and the upcoming 6G networks is the rapid fluctuation in signal quality across various beam directions. Extremely high-frequency waves are highly vulnerable to obstruction, making even slight adjustments in device orientation or the presence of blockers capable of causing substantial fluctuations in link quality along a designated path. This issue poses a major obstacle because numerous applications with low-latency requirements necessitate the precise forecasting of network quality from many directions and cells. The method proposed in this research demonstrates an avant-garde approach for assessing the quality of multi-directional …

Drosophila Nhe2 Overexpression Induces Autophagic Cell Death, Jobelle Peralta, Blake Dupriest, Daniel Orozco, Juan Reyna Pacheco, Laura Martins, Rachel Ann Soriano, Alan Wong, Ramy Wong, Bree Grillo-Hill

Faculty Research, Scholarly, and Creative Activity

Autophagy is a conserved catabolic process where double membrane-bound structures form around macromolecules or organelles targeted for degradation. Autophagosomes fuse with lysosomes to facilitate degradation and macromolecule recycling for homeostasis or growth in a cell autonomous manner. In cancer cells, autophagy is often up-regulated and helps cancer cells survive nutrient deprivation and stressful growth conditions. Here, we propose that the increased intracellular pH (pHi) common to cancer cells is sufficient to induce autophagic cell death. We previously developed tools to increase pHi in the Drosophila eye via overexpression of DNhe2, resulting in aberrant patterning and reduced tissue size. We examined …

Context. Mid-infrared emission features are important probes of the properties of ionized gas and hot or warm molecular gas, which are difficult to probe at other wavelengths. The Orion Bar photodissociation region (PDR) is a bright, nearby, and frequently studied target containing large amounts of gas under these conditions. Under the “PDRs4All” Early Release Science Program for JWST, a part of the Orion Bar was observed with MIRI integral field unit (IFU) spectroscopy, and these high-sensitivity IR spectroscopic images of very high angular resolution (0.2′′) provide a rich observational inventory of the mid-infrared (MIR) emission lines, while resolving the H …

Reading Colonial Transitions: Archival Evidence And The Archaeology Of Indigenous Action In Nineteenth-Century California, Lee M. Panich, Gustavo Flores, Michael Wilcox, Monica V. Arellano

Faculty Research, Scholarly, and Creative Activity

Archaeologists in North America and elsewhere are increasingly examining long-term Indigenous presence across multiple colonial systems, despite lingering conceptual and methodological challenges. We examine this issue in California, where archaeologists and others have traditionally overlooked Native persistence in the years between the official closing of the region’s Franciscan missions in the 1830s and the onset of US settler colonialism in the late 1840s. In particular, we advocate for the judicious use of the documentary record to ask new questions of Indigenous life during this short but critical period, when many Native Californians were freed from the missions and sought new …

Exploring Performance-Based Contracts: A Good Option To Address Long-Term Road Maintenance In California?, Maria Calahorra-Jimenez, Richard Poythress
