Rapid Arctic environmental change affects the entire Earth system as thawing permafrost ecosystems release greenhouse gases to the atmosphere. Understanding how much permafrost carbon will be released, over what time frame, and what the relative emissions of carbon dioxide and methane will be is key for understanding the impact on global climate. In addition, the response of vegetation in a warming climate has the potential to offset at least some of the accelerating feedback to the climate from permafrost carbon. Temperature, organic carbon, and ground ice are key regulators for determining the impact of permafrost ecosystems on the global carbon …

The Emergence Of Psychoanalytical Electrochemistry: The Translation Of Mdd Biomarker Discovery To Diagnosis With Electrochemical Sensing, Priyanka M. Nadar, Mckenna A. Merrill, Katherine Austin, Stephen M. Strakowski, Jeffrey M. Halpern

Faculty Publications

The disease burden and healthcare costs of psychiatric diseases along with the pursuit to understand their underlying biochemical mechanisms have led to psychiatric biomarker investigations. Current advances in evaluating candidate biomarkers for psychiatric diseases, such as major depressive disorder (MDD), focus on determining a specific biomarker signature or profile. The origins of candidate biomarkers are heterogenous, ranging from genomics, proteomics, and metabolomics, while incorporating associations with clinical characterization. Prior to clinical use, candidate biomarkers must be validated by large multi-site clinical studies, which can be used to determine the ideal MDD biomarker signature. Therefore, identifying valid biomarkers has been challenging, …

Adsorption Of Helium And Hydrogen On Triphenylene And 1,3,5-Triphenylbenzene, Bergmeister Bergmeister, Kollotzek Kollotzek, Florent Calvo, Elisabeth Gruber, Fabio Zappa, Paul Scheier, Olof E. Echt

Faculty Publications

The adsorption of helium or hydrogen on cationic triphenylene (TPL, C₁₈H₁₂), a planar polycyclic aromatic hydrocarbon (PAH) molecule, and of helium on cationic 1,3,5-triphenylbenzene (TPB, C₂₄H₁₈), a propeller-shaped PAH, is studied by a combination of high-resolution mass spectrometry and classical and quantum computational methods. Mass spectra indicate that He_nTPL⁺ complexes are particularly stable if n = 2 or 6, in good agreement with the quantum calculations which show that for these sizes the helium atoms are strongly localized on either side of the central carbon ring for n = …

A Global Assessment Of The Mixed Layer In Coastal Sediments And Implications For Carbon Storage, Shasha Song, Isaac R. Santos, Huaming Yu, Faming Wang, William C. Burnett, Thomas S. Bianchi, Junyu Dong, Ergang Lian, Bin Zhao, Lawrence Mayer, Qingzhen Yao, Zhigang Yu, Bochao Xu

Center for Coastal and Ocean Mapping

The sediment-water interface in the coastal ocean is a highly dynamic zone controlling biogeochemical fluxes of greenhouse gases, nutrients, and metals. Processes in the sediment mixed layer (SML) control the transfer and reactivity of both particulate and dissolved matter in coastal interfaces. Here we map the global distribution of the coastal SML based on excess 210Pb (210Pbex) profiles and then use a neural network model to upscale these observations. We show that highly dynamic regions such as large estuaries have thicker SMLs than most oceanic sediments. Organic carbon preservation and SMLs are inversely related as mixing stimulates oxidation in sediments …

Designing An Interchangeable Multi-Material Nozzle System For The 3d Bioprinting Process, Cartwright Nelson, Slesha Tuladhar, Md Habib

New Hampshire EPSCoR

Three-dimensional bioprinting is a rapidly growing field attempting to recreate functional tissues for medical and pharmaceutical purposes. Development of functional tissue requires deposition of multiple biomaterials encapsulating multiple cell types i.e. bio-ink necessitating switching ability between bio-inks. Existing systems use more than one print head to achieve this complex interchangeable deposition, which decreases efficiency, structural integrity, and accuracy. In this research, we developed a nozzle system capable of switching between multiple bio-inks with continuous deposition ensuring the minimum transition distance so that precise deposition transitioning can be achieved. Finally, the effect of rheological properties of different bio-material compositions on the …

Personal Intelligence Is Evident In The Sophistication Of People’S Narratives About Personality, Jayne L. Allen, John D. Mayer

UNH Personality Lab

Personal intelligence concerns the ability to understand personality in oneself and others—including the understanding of motives, socioemotional traits, and abilities. We examined if people’s scores on the ability-based Test of Personal Intelligence (TOPI) would be reflected in their narratives about someone whose personality they had learned about. In a Preliminary Study (N = 220), we collected narratives and open-ended descriptions about their learning. In Study 1 (N = 212), experts rated the respondents’ open-ended narratives for their sophistication about personality, defined as their knowledge and complexity of thought around the topic. Respondents also filled out checklists concerning what they learned …

Microtopography Matters: Belowground Ch4 Cycling Regulated By Differing Microbial Processes In Peatland Hummocks And Lawns, Clarice R. Perryman, Carmody K. Mccalley, Jessica G. Ernakovich, Louis J. Lamit, Joanne H. Shorter, Erik Lilleskov, Ruth K. Varner

Faculty Publications

Water table depth and vegetation are key controls of methane (CH4) emissions from peatlands. Microtopography integrates these factors into features called microforms. Microforms often differ in CH4 emissions, but microform-dependent patterns of belowground CH4 cycling remain less clearly resolved. To investigate the impact of microtopography on belowground CH4 cycling, we characterized depth profiles of the community composition and activity of CH4-cycling microbes using 16S rRNA amplicon sequencing, incubations, and measurements of porewater CH4 concentration and isotopic composition from hummocks and lawns at Sallie's Fen in NH, USA. Geochemical proxies of methanogenesis and methanotrophy indicated that microforms differ in dominant microbial …

The development of robust chronologies of Neoglaciation from individual glaciers throughout the high-altitude Andes can provide fundamental knowledge of influences such as regional temperature and precipitation variability, and aid in predicting future changes in the Andean climate system. However, records of Late Holocene glaciation from the Central Chilean Andes are sparse, and often poorly constrained. Here, we present ³⁶Cl surface exposure ages, dendrochronologic constraints, and glacial mass balance modeling simulations of Late Holocene glacier fluctuations in the Central-South Chilean Andes. A series of concentric moraine ridges were identified on Monte Sierra Nevada (38°S), where exposure dating of basaltic boulders …

Climate change is an existential threat to the vast global permafrost domain. The diverse human cultures, ecological communities, and biogeochemical cycles of this tenth of the planet depend on the persistence of frozen conditions. The complexity, immensity, and remoteness of permafrost ecosystems make it difficult to grasp how quickly things are changing and what can be done about it. Here, we summarize terrestrial and marine changes in the permafrost domain with an eye toward global policy. While many questions remain, we know that continued fossil fuel burning is incompatible with the continued existence of the permafrost domain as we know …

Brown carbon (BrC) associated with aerosol particles in western United States wildfires was measured between July and August 2019 aboard the NASA DC-8 research aircraft during the Fire Influence on Regional to Global Environments and Air Quality (FIREX-AQ) study. Two BrC measurement methods are investigated, highly spectrally resolved light absorption in solvent (water and methanol) extracts of particles collected on filters and in situ bulk aerosol particle light absorption measured at three wavelengths (405, 532 and 664 nm) with a photoacoustic spectrometer (PAS). A light-absorption closure analysis for wavelengths between 300 and 700 nm was performed. The combined light absorption of particle …

The physical and chemical changes that accompany permafrost thaw directly influence the microbial communities that mediate the decomposition of formerly frozen organic matter, leading to uncertainty in permafrost–climate feedbacks. Although changes to microbial metabolism and community structure are documented following thaw, the generality of post-thaw assembly patterns across permafrost soils of the world remains uncertain, limiting our ability to predict biogeochemistry and microbial community responses to climate change. Based on our review of the Arctic microbiome, permafrost microbiology, and community ecology, we propose that Assembly Theory provides a framework to better understand thaw-mediated microbiome changes and the implications for community …

Three Observations About Justice Alito's Draft Opinion In Dobbs - Commentary, John M. Greabe

Law Faculty Scholarship

[Excerpt] "There is much to say about Justice Samuel Alito's draft opinion in Dobbs v. Jackson Women's Health Organization, which was leaked from the United States Supreme Court on May 2 [2022].

Obviously, the most significant direct consequence of the proposed decision, which overrules Roe v. Wade (1973) and Planned Parenthood v. Casey (1992) while upholding the constitutionality of a Mississippi law that outlaws most abortions after 15 weeks of pregnancy, would be the restriction or elimination of abortion services throughout much of the nation. This will have all sorts of attendant consequences, large and smaller, many of which …

Oxen: Status, Uses And Practices In The U.S.A., Encouraging A Historic Tradition To Thrive, Andrew B. Conroy

Faculty Publications

Oxen in the United States of America have played an important role throughout its history. Unlike other countries,oxen were never completely given up for horses, mules, or tractors. Instead, the culture of keeping oxen has been maintained by a small group of teamsters in the North- eastern states collectively called New England. Their continued presence has been largely due to agricultural fairs and exhibitions where they have been used in competition for the last 200 years. Ox teamsters were sur- veyed in 2021via social media using Qualtrics. The 423 ox teamsters responding owned 1791 oxen in 39 states, with the …

You may see these tiny fish swimming in bowls at the county fair, but left alone in a lake or large pond, where they are dropped perhaps by a well-meaning child, they can grow to 20 pounds or more— and destroy ecosystems. The goldfish is a cautionary tale that has been told time and again in different forms, like Pandora’s box."

Equity Vs. Equality: How Differing Viewpoints Choose To Portray History, Sara Donatello

Comm-entary

This paper explores the themes of equity and equality, defining the terms and applying them to projects done by civil rights activists Nikole Hannah-Jones and Robert Woodson, and a government commission created by Donald Trump. The 1619 Project, founded by Hannah-Jones, pushes the narrative of equity, following the idea of the politics of difference. 1776 Unites, founded by Robert Woodson, provided a counterargument to the 1619 Project, and follows the politics of universalism and equality, holding everyone in the same esteem. Finally, the 1776 Commission, created by Donald Trump, is not associated with 1776 Unites but follows the same narrative …

The Effects Of Disorder In Van Der Waals Materials, Jake Riffle

Doctoral Dissertations

Due to their two-dimensional structure and wide range of electronic behaviors, van derWaals materials have garnered a lot of attention for new technological applications. However, much is still unknown about the consequences that impurities and disorder have on the performance of many new van der Waals materials. In my research I use scanning tunneling microscopy(STM) and electronic transport techniques to study the different types of disorder in three common van der Waals materials: tantalum disulfide (TaS2), black phosphorus (BP), and two-dimensional graphene. In TaS2 I show a sample preparation dependence on the surface state of the bulk crystal and emphasize …
