Investigation Of Retention And Dehydration Of Preformed Particle Gel For Conformance Control In Fractured Carbonates, Abdulaziz A. Almakimi, Abdullah O. Almansour, Junchen Liu, Baojun Bai, Ibnelwaleed A. Hussein

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Preformed particle gel (PPG) treatment has proved to be among the most effective methods to reduce excessive water production in fractured reservoirs. The blocking ability of PPGs to fractures or fracture-like features is highly dependent on injected gel properties and volume. Gel dehydration during extrusion through fracture is common and has a considerable effect on gel properties, transport, and plugging efficiency. As the gel particles propagate through the fracture, continuous dehydration is often associated and causes the gel to concentrate and require high-pressure gradients to move. Dehydration might be desirable to a certain limit because it can help to form …

Classical trajectory Monte Carlo calculations for 1 keV positron impact ionization of argon are presented. A combination of energy-weighted triple differential cross-sections is shown to provide good to excellent agreement compared with experimental data, depending on the ejected electron azimuthal angular acceptance range used to define in-plane scattering. For ejected electron energies less than 100 eV, information about the influence of pre- (the impact parameter) and post-(the direction of scattering) collision kinematics on the triple differential level is obtained. An overall picture of these kinematic properties is also presented for single differential cross-sections as a function of ejected electron energy …

From Idea To Action: Defining And Measuring Voice Implementation, Ann E. Schlotzhauer, Mark G. Ehrhart

Psychological Science Faculty Research & Creative Works

Despite increasing interest in the topic, research on managerial responses to voice is underdeveloped. In this article, we differentiate voice implementation from voice appreciation to add much-needed nuance to our understanding of how voice targets respond to voice behavior. We define voice implementation as the extent to which a voice target undertakes voluntary effort with the goal of enacting a suggestion from a voicer, including attempting to put a suggestion into action and/or advocating for the idea to those with the power to enact the suggestion. A 5-item scale based on this definition demonstrated strong content validity, construct validity, and …

Photoluminescent defects in diamond, such as the nitrogen-vacancy (NV) color center, are at the forefront of emerging optical quantum technologies. Most emit in the visible and near-infrared spectral region below 1000 nm (NIR-I), limiting their applications in photonics, fiber communications, and biology. Here, we show that the nitrogen-vacancy-nitrogen (N2V) center, which emits in the visible and near-infrared-II (NIR-II, 1000-1700 nm), is ubiquitous in as-synthesized and processed nitrogen-doped diamond, ranging from bulk samples to nanoparticles. We demonstrate that N2V is also present in commercially available state-of-the-art NV diamond sensing chips made via chemical vapor deposition (CVD). In high-pressure high-temperature (HPHT) diamonds, …

Extended gamma-ray emission around isolated pulsars at TeV energies, also known as TeV halos, have been found around a handful of middle-aged pulsars. The halos are significantly more extended than their pulsar wind nebulae but much smaller than the particle diffusion length in the interstellar medium. The origin of TeV halos is unknown. Interpretations invoke either local effects related to the environment of a pulsar or generic particle transport behaviors. The latter scenario predicts that TeV halos would be a universal phenomenon for all pulsars. We searched for extended gamma-ray emission around 36 isolated middle-aged pulsars identified by radio and …

The Anorexigenic Peptide Nesfatin-1 Dampens The B Cell Response To Receptor-Mediated Stimulation Through Inhibition Of Nf-Jb Signaling, Tara L. Steffen, Joshua D. Stafford, Colleen R. Bocke, Willis K. Samson, Gina L.C. Yosten

Biological Sciences Faculty Research & Creative Works

Nesfatin-1, a posttranslational product of the protein encoded by the nucleobindin 2 gene (NUCB2), was functionally identified as an appetite regulatory molecule in rat hypothalamic nuclei. In the years following the discovery, those findings have been corroborated and expanded upon, and we now know that nesfatin-1 is expressed throughout peripheral tissues and exerts physiological effects beyond feeding control. Literature indicates that adipose tissue is one of the peripheral sources of NUCB2/nesfatin-1, and in this setting, it has anti-inflammatory effects that have recently been implicated in regulating chronic inflammation associated with diet-induced obesity. Currently, there are gaps in our understanding of …

Variable Selection In Mixture Cure Models Using Elastic Net Penalty: Application To Covid-19 Data, Aluwani Ramalata, Akim Adekpedjou, Maseka Lesaoana

Mathematics and Statistics Faculty Research & Creative Works

In survival analysis, it is often assumed that all individuals will eventually experience the event of interest if followed long enough. However, in many real-world scenarios, a subset of individuals remains event-free indefinitely. For instance, in clinical studies, some patients never relapse and are considered cured rather than censored. Traditional survival models are inadequate for capturing this heterogeneity. Mixture cure models address this limitation by distinguishing between cured and susceptible individuals while modeling the survival of the latter. A key challenge in mixture cure modeling is selecting relevant covariates, particularly when dealing with time-varying effects. This study develops a penalized …

Re-Analysis Of The Anthropogenic Effect Of The Covid-19 Global Lockdown On Night-Time Lunar Surface Temperatures, W. Schonberg, S. Haque

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

A study by Durga Prasad and Ambily observed an anomalous decrease in the lunar surface temperatures during the period April–May 2020, which they then attributed to the anthropogenic effects of the COVID-19 global lockdown effect. We have re-examined their data and while the anomalous decrease in the lunar surface temperature during April–May 2020 appears in our analysis as well, so does another significant dip in early 2018. Furthermore, the decline to the minimum observed during April–May 2020 is seen to begin in 2019, that is, quite some time before the COVID-19 event that led to the global lockdown and the …

Reflections On Linear B, (Part 11): Linear B Sign 55 And The Ancient Egyptian Wish For An Eternity Of Life Or Rule, Gerald Leonard Cohen

Arts, Languages and Philosophy Faculty Research & Creative Works

Linear B sign 55 (pronounced /nu/) is evidently of unknown origin, and the present article suggests a possible solution. As with several other Linear B signs I have treated, the solution is sought in Egyptian hieroglyphs, only this time two hieroglyphs are required for the solution (one for the shape, one for the pronunciation).

The shape of the Linear B sign is explainable as a simplified and somewhat altered form of a similarly shaped Egyptian hieroglyph which was pronounced /ḥeḥ/ and meant ‘a great but indefinite number;’ then by extension: ‘eternity’ and from there to Ḥeḥ, a god symbolizing eternity. …
