2020-Current year OA Pubs

The study aimed to improve outcomes in Nucleus cochlear implant (CI) recipients with single-sided deafness (SSD) by reducing interaural frequency and loudness mismatches through device programming. In Experiment 1a, a modified frequency allocation table (FAT) was created to better match the tonotopicity of the contralateral ear and reduce interaural frequency mismatch. Twenty experienced SSD-CI users completed localization and speech recognition tests with their everyday FAT. Tests were repeated after 6 weeks' use of the modified FAT. Participants compared both FATs for 2 weeks before being tested again with each. For 10 newly implanted SSD-CI recipients (Experiment 1b), Group A was …

Examining The Presence And Effects Of Coherence And Fragmentation In The Gulf Of Maine Fishery Management Network, Derek A. Katznelson, Antonia Sohns, Dongkyu Kim, Evelyn Roozee, William Donner, Andrew M. Song, Jasper R. De Vries, Owen Temby, Gordon M. Hickey

School of Earth, Environmental, & Marine Sciences Faculty Publications

Natural resource management networks cohere due to mutual dependencies and fragment, in part, due to the perceived risks of interaction. However, research on these networks has tended to accept coherence a priori rather than problematizing dependence, and few studies exist on interorganizational risk perception. This article presents the results of a study operationalizing these concepts and measuring the distribution of three types of dependence (capital, legitimacy, and regulatory) and two types of perceived risk (performance and sanction) among nearly fifty stakeholder groups and organizations participating in the management of fisheries in the binational Gulf of Maine. The analysis reveals an …

Loss Of Endogenous Circadian Clock Function In Mice Alters Respiratory Cycle Timing In A Time Of Day- And Sex-Specific Manner, Aaron A. Jones, Deanna M. Arble

Biological Sciences Faculty Research and Publications

Resting breathing and ventilatory chemoreflexes are regulated in a 24-hr manner by the endogenous circadian clock. However, it is unclear how circadian biology influences different phases of the breath-to-breath respiratory cycle which are predominantly controlled by pontomedullary regions of the brainstem. Here, we performed whole-body plethysmography during quiet wakefulness in young adult male and female mice lacking the core clock gene Brain and Muscle Arnt-like 1 (BMAL1) to determine the extent to which the molecular clock affects respiratory cycle timing and ventilatory airflow mechanics. Breath waveform analysis revealed that male BMAL1 knockout (KO) mice exhibit time of day-specific differences in …

Elephant Megacarcasses Increase Local Nutrient Pools In African Savanna Soils And Plants, Courtney G. Reed, Michelle L. Budny, Johan T. Du Toit, Ryan Helcoski, Joshua P. Schimel, Izak P.J. Smit, Tercia Strydom, Aimee Tallian, Dave I. Thompson, Helga Van Coller, Nathan P. Lemoine, Deron E. Burkepile

Biological Sciences Faculty Research and Publications

African elephants (Loxodonta africana) are the largest extant terrestrial mammals, with bodies containing enormous quantities of nutrients. Yet, we know little about how these nutrients move through the ecosystem after an elephant dies. Here, we investigated the initial effects (1–26 months postmortem) of elephant megacarcasses on savanna soil and plant nutrient pools in the Kruger National Park, South Africa. We hypothesized that (H1) elephant megacarcass decomposition would release nutrients into soil, resulting in higher concentrations of soil nitrogen (N), phosphorus (P), and micronutrients near the center of carcass sites; (H2) carbon (C) inputs into the soil would stimulate …

Long-Term Increases In Wing Length Occur Independently Of Changes In Climate And Climate-Driven Shifts In Body Size, Tiffany Dias, Nathan P. Lemoine, Scott W. Yanco, Marketa Zimova, Rachael A. Bay, Brian C. Weeks

Biological Sciences Faculty Research and Publications

Recent widespread reductions in body size across species have been linked to increasing temperatures; simultaneous increases in wing length relative to body size have been broadly observed but remain unexplained. Size and shape may change independently of one another, or these morphological shifts may be linked, with body size mediating or directly driving the degree to which shape changes. Using hierarchical Bayesian models and a morphological time series of 27 366 specimens from five North American migratory passerine bird species, we tested the roles that climate and body size have played in shifting wing length allometry over four decades. We …

2020-Current year OA Pubs

Age is a significant risk factor for mild cognitive impairment (MCI) and Alzheimer's disease (AD) and identifying brain age patterns is critical for comprehending the normal aging and MCI/AD processes. Prior studies have widely established the univariate relationships between brain regions and age, while multivariate associations remain largely unexplored. Herein, various artificial intelligence (AI) models were used to perform brain age prediction using an MRI dataset (

Phase I Study Of Nt-I7, A Long-Acting Interleukin-7, In Severe Treatment-Related Lymphopenia Following Standard Radiation And Temozolomide For High-Grade Glioma, Jian L Campian, Milan G Chheda, John F Dipersio, Et Al.

2020-Current year OA Pubs

BACKGROUND: High-grade gliomas (HGG) have a poor prognosis despite aggressive treatment. Severe, persistent lymphopenia occurring in HGG patients after concurrent chemoradiation is associated with worse survival. NT-I7, a long-acting interleukin-7 analog, has been shown to increase CD4 and CD8 counts in healthy, septic, and HIV-positive adults. This multi-institutional, NCI-funded dose-escalation trial is the first to evaluate NT-I7 safety and activity in HGG patients with severe treatment-related lymphopenia (TRL) and the effect of co-administered glucocorticoids.

METHODS: Eligible HGG patients had CD4 counts < 300 cells/mm

RESULTS: NT-I7 was well tolerated in all 12 patients (median age 64; median CD4 count 161 cells/mm³) before the …

The Lim-7p::Ced-1::Gfp Transgene From The Md701 Strain Increases Embryonic Lethality In C. Elegans, Nina M. Zampetti, Kristin A. Quaglia, Lisa N. Petrella

Biological Sciences Faculty Research and Publications

The lim-7p::ced-1::GFP transgene has been widely used for evaluating germline apoptosis in C. elegans. Here we observed an increase in embryonic lethality in the MD701 strain that contains the lim-7p::ced-1::GFP transgene and a strain that outcrossed the lim-7p::ced-1::GFP transgene into the N2 wild-type strain. While the outcrossed strain had a significantly lower level of embryonic lethality than MD701, it still showed significantly higher embryonic lethality than wild type. Our results suggest that the presence of the lim-7p::ced-1::GFP transgene significantly increases embryonic lethality, but there may also be a secondary mutation in the MD701 strain that further increases embryonic lethality.

The Swiping Desire: Intimacy, Libidinal Capitalism, And The Digital Subject In The Tinder Swindler, Chanif Ainun Naim

Masyarakat: Jurnal Sosiologi

This article examines how dating applications operate as libidinal infrastructures that restructure and commodify intimacy within platform capitalism, using The Tinder Swindler as a cultural case study. Employing a visual-narrative approach within the framework of Critical Discourse Analysis, the film is analyzed to reveal the structural exploitation of user affect and desire. Grounded in Lacanian psychoanalysis and Baudrillard’s simulation theory, the study argues that these platforms capitalize on the subject’s ontological lack (manque) which fuels desire as the desire for the Other’s desire. This psychic lack sustains a perpetual pursuit of recognition that can never be fulfilled. The swindler’s hyper-curated …
