The capacity of aquatic systems to buffer acidification depends on the sum contributions of various chemical species to total alkalinity (TA). Major TA contributors are inorganic, with carbonate and bicarbonate considered the most important. However, growing evidence shows that many rivers, estuaries, and coastal waters contain dissolved organic molecules with charge sites that create organic alkalinity (OrgAlk). This study describes the first comparison of (1) OrgAlk distributions and (2) acid–base properties in contrasting estuary-plume systems: the Pleasant (Maine, USA) and the St. John (New Brunswick, CA). The substantial concentrations of OrgAlk in each estuary were sometimes not conservative with salinity …

Researchers have examined the influence of the factors on reducing return rates in retailing over the years. However, the returns experience is often an overlooked way to drive customer engagement and repeat sales in the now ubiquitous omnichannel setting. The focus on returns prevention in existing research overshadows management’s need to understand better the comprehensive mechanics linking the customer in-store return experience with their repurchase actions. Recognizing the need to bridge different stages of the returns management process, this research aims to explore the facilitators and barriers of in-store return activities.

El concepto del héroe quijotesco ha sido propuesto como modelo a seguir como parte de los esfuerzos nacionalizadores del régimen de Francisco Franco (1939-75). A diferencia de los símbolos formales de la nación española, como la bandera y el himno, que nunca se desasociaron políticamente por completo de la dictadura, el retrato como héroes nacionales de ciertos deportistas en disciplinas individuales los convirtió en exitosos símbolos informales de la nación española y su supuesto carácter nacional. El tenista Manolo Santana, cuya carrera cubrió principalmente la década de los 60, fue uno de los héroes quijotescos originales del deporte español, cuya …

Controlled intracellular delivery of biomolecular cargo is critical for developing targeted therapeutics and cell reprogramming. Conventional delivery approaches (e.g., endocytosis of nano-vectors, microinjection, and electroporation) usually require time-consuming uptake processes, labor-intensive operations, and/or costly specialized equipment. Here, we present an acoustofluidics-based intracellular delivery approach capable of effectively delivering various functional nanomaterials to multiple cell types (e.g., adherent and suspension cancer cells). By tuning the standing acoustic waves in a glass capillary, our approach can push cells in flow to the capillary wall and enhance membrane permeability by increasing membrane stress to deform cells via acoustic radiation forces. Moreover, by coating …

Frequent and unresolved conflict is a significant relationship risk factor for divorce, but it has also been shown that religion strengthens marriages, specifically in ways that give direction and motivation for couples in resolving marital conflict or other marital hardships. Thus, a study of how successful religious couples resolve conflict is pertinent in helping us better understand how to strengthen marriages and families. Our qualitative study of 113 highly religious women of diverse faiths and races found that women’s perceived relationship or connection with God reportedly impacted conflict resolution and coping with marital hardship. Results suggest greater reconciliation and unity …

Syntactic processing and verbal working memory are both essential components to sentence comprehension. Nonetheless, the separability of these systems in the brain remains unclear. To address this issue, we performed causal-inference analyses based on lesion and connectome network mapping using MRI and behavioural testing in two groups of individuals with chronic post-stroke aphasia. We employed a rhyme judgement task with heavy working memory load without articulatory confounds, controlling for the overall ability to match auditory words to pictures and to perform a metalinguistic rhyme judgement, isolating the effect of working memory load (103 individuals). We assessed non-canonical sentence comprehension, isolating …
New Insights Into Supradense Matter From Dissecting Scaled Stellar Structure Equations, Bao-Jun Cai, Bao-An Li
New Insights Into Supradense Matter From Dissecting Scaled Stellar Structure Equations, Bao-Jun Cai, Bao-An Li
Faculty Publications
The strong-field gravity in general relativity (GR) realized in neutron stars (NSs) renders the equation of state (EOS) P(ε) of supradense neutron star matter to be essentially nonlinear and refines the upper bound for ϕ≡P/ε to be much smaller than the special relativity (SR) requirement with linear EOSs, where P andεare respectively the pressure and energy density of the system considered. Specifically, a tight bound ϕ ≲ 0.374 is obtained by perturbatively anatomizing the intrinsic structures of the scaled Tolman–Oppenheimer–Volkoff (TOV) equations without using any input nuclear EOS. New insights gained from this novel analysis provide EOS-model-independent constraints on the …

Structure Of A Model Lipid Membrane Oxidized By Human 15-Lipoxygenase-2, Jamil Nemri, Cosme Morales, Nathaniel C. Gilbert, Jaroslaw Majewski, Marcia E. Newcomer, Crystal M. Vander Zanden
Faculty Publications
Enzyme-mediated lipid oxidation is an important regulatory event in cell signaling, with oxidized lipids being potent signaling molecules that can illicit dramatic changes in cell behavior. For example, peroxidation of an arachidonoyl poly-unsaturated fatty acid by the human enzyme 15-lipoxygenase-2 (15-LOX-2) has been associated with formation of atherosclerotic plaques. Previous work on synthetically oxidized membranes has shown that oxidized lipid tails will change their conformation to facilitate interactions between the peroxide group and the lipid headgroups. However, this phenomenon has not been directly observed for a lipid membrane that has undergone enzyme-catalyzed oxidation. In this study, we report on the …

The development of stable and buffered reference electrodes (REs) is crucial for molten salt electrochemistry, particularly in pyrochemical processing, such as electrorefining. These REs must maintain a stable potential to ensure precise control over electrorefining processes by preventing unwanted shifts in the potential that could lead to impurity deposition. This study evaluated metal chlorides and metal oxides as potential candidates for REs, with their stability assessed via electrochemical methods over extended durations. While metal chloride-based REs exhibited stable potential behavior over time, their response followed the Nernst equation, leading to potential shifts with varying concentrations of oxidized species. Metal oxide-based …

Library personnel are now expected to act as first responders and crisis leaders during times such as natural disasters. This report documents the critical crisis leadership qualifications required for library personnel, identified through comprehensive research from 2015 to 2023. Findings from these situation-specific case studies call attention to the community’s needs for library services during emergencies, underscoring the requirement for LIS education to include disaster management. Continuing education (CE) is also critical in preparing information professionals for these essential roles.
How Should Scientists Act? Assessing Public Perceptions Of Scientists And Scientific Practices And Their Implications For Science Communication, Thomas G. Safford, Emily H. Whitmore
How Should Scientists Act? Assessing Public Perceptions Of Scientists And Scientific Practices And Their Implications For Science Communication, Thomas G. Safford, Emily H. Whitmore
Faculty Publications
Is how science is conducted legitimate? Are scientists trustworthy? Whether the public answers “yes” to these questions is critical for science communicators. We explore how social factors affect public perceptions of the practice of science, and then test how those beliefs relate to views about how scientists engage with the public and policy making. Our results show that political ideology and religiosity affect these views. However, more importantly, respondents’ concerns about the integrity of the scientific process are the strongest predictor of views about scientists’ behavior, providing a focus area for future communication efforts in support of science-based decision making.

Electrostatic dispersion can significantly impact the microphysical behavior of charged particles and ions until reaching zero space charge. However, although radioactive particles can be strongly charged in air, the influence of electrostatic dispersion has been neglected in understanding their behavior. This study is aimed at investigating the time evolution of the charge and size distributions of radioactive and nonradioactive particles in air and developing simple approaches for applications. With processes involving charging, aggregation, and electrostatic dispersion, a comprehensive population balance model (PBM) has been developed to examine particle charge/size distribution dynamics. It is shown that compared to nonradioactive particles, the …

Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare genetic condition characterized by features of accelerated aging, and individuals with HGPS seldom live beyond their mid-teens. The syndrome is commonly caused by a point mutation in the LMNA gene which codes for lamin A and its splice variant lamin C, components of the nuclear lamina. The mutation causing HGPS leads to production of a truncated, farnesylated form of lamin A referred to as "progerin." Progerin is also expressed at low levels in healthy individuals and appears to play a role in normal aging. HGPS is associated with an accumulation of genomic DNA …

Coastal wetlands are one of the most productive ecosystems on Earth with the capacity to sequester large amounts of carbon dioxide (CO2). Wetland loss due to anthropogenic and natural causes reduces the carbon (C) storage capacity and potentially releases previously fixed C in biomass and soil to the water column and atmosphere through decomposition. Coastal wetland restoration has the potential to mitigate some of the C losses depending on the balance of C fluxes. However, the role of vegetation and environmental conditions in governing rates of C accumulation in restoration sites is not well resolved. The purpose of this study …

Although mangroves provide many beneficial ecosystem services, such as blue carbon storage and coastal protection, they are currently under threat due to changes in climate conditions, such as prolonged drought exposure. Under drought conditions, evaporation exceeds precipitation and high soil salinities can lead to stunted growth and die-back. To quantify this interplay, we developed a database for low-lying and uninhabited mangrove islands in the Caribbean under various evaporation and precipitation regimes. We extracted physical and biological information from each island using remote sensing techniques and coupled it with a process-based model. We used this database to develop a model that …
