      Background: Antivirals are needed to combat the COVID-19 pandemic, which is caused by SARS-CoV-2. The clinically-proven protease inhibitor Camostat mesylate inhibits SARS-CoV-2 infection by blocking the virus-activating host cell protease TMPRSS2. However, antiviral activity of Camostat mesylate metabolites and potential viral resistance have not ...
    • Campana points of bounded height on vector group compactifications 

      Pieropan, Marta; Smeets, Arne; Tanimoto, Sho; Várilly-Alvarado, Anthony (2021)
      We initiate a systematic quantitative study of subsets of rational points that are integral with respect to a weighted boundary divisor on Fano orbifolds. We call the points in these sets Campana points. Earlier work of Campana and subsequently Abramovich shows that there are several reasonable competing definitions for Campana points. We use a version ...
    • Can complex systems really be simulated? 

      (2014)
      The simulation of complex systems is important in many fields of science and in real-world applications. Such systems are composed of many interacting subsystems. There might exist different software packages for simulating the individual subsystems and co-simulation refers to the simultaneous execution of multiple interacting subsystem simulators. ...
    • Can Gap Tuning Schemes of Long-Range Corrected Hybrid Functionals Improve the Description of Hyperpolarizabilities? 

      (2014)
      Long-range corrected hybrid density functionals (LC-DFT), with range separation parameters optimally tuned to obey Koopmans' theorem, are used to calculate the first-order hyperpolarizabilities of prototypical charge-transfer compounds p-nitroaniline (PNA) and dimethylamino nitrostilbene (DANS) in the gas phase and various solvents. It is shown that ...
    • Can I Rely on You? 

      Aksoy, Billur; Eckel, Catherine C.; Wilson, Rick K. (2018)
      This paper introduces a strategic element into the dictator game by allowing recipients to select their dictator. Recipients are presented with the photographs of two dictators and the envelopes containing their allocations, and are then asked to select which dictator’s gift they would like to receive. The recipient is paid the contents of the envelope ...
    • Can postoperative process of care utilization or complication rates explain the volume-cost relationship for cancer surgery? 

      Ho, Vivian; Short, Marah N.; Aloia, Thomas A. (2017)
      Background: Past studies identify an association between provider volume and outcomes, but less is known about the volume-cost relationship for cancer surgery. We analyze the volume-cost relationship for 6 cancer operations and explore whether it is influenced by the occurrence of complications and/or utilization of processes of care. Methods: Medicare ...
    • Can Religiosity Be Explained by ‘Brain Wiring’? An Analysis of US Adults’ Opinions 

      Mehta, Sharan Kaur; Scheitle, Christopher P.; Ecklund, Elaine Howard (2019)
      Studies examining how religion shapes individuals’ attitudes about science have focused heavily on a narrow range of topics, such as evolution. This study expands this literature by looking at how religion influences individuals’ attitudes towards the claim that neuroscience, or “brain wiring,” can explain differences in religiosity. Our analysis of ...
    • Can Reservoir Regulation Along the Yellow River Be a Sustainable Way to Save a Sinking Delta? 

      Wu, Xiao; Bi, Naishuang; Syvitski, Jaia; Saito, Yoshiki; Xu, Jingping; (2020)
      Today's deltas are impacted negatively by (1) accelerated subsidence (e.g., from ground fluid extraction), (2) global eustatic sea level rise, and (3) decreased sediment supply, which increasingly starves these landforms of sediment necessary to sustain their footprint. This growing vulnerability threatens many megacities that have developed due to ...
    • Can Short- and Middle-Range Hybrids Describe the Hyperpolarizabilities of Long-Range Charge-Transfer Compounds? 

      (2014)
      The hyperpolarizabilities of five prototypical and four recently synthesized long-range charge-transfer (CT) organic compounds are calculated using short- and middle-range (SR and MR) hybrid functionals. These results are compared with data from MP2 and other DFT methods including GGAs, global hybrids, long-range corrected functionals (LC-DFT), and ...
    • Can we understand the mechanisms of tumor formation by analyzing dynamics of cancer initiation? 

      Teimouri, Hamid; Kolomeisky, Anatoly B.; Center for Theoretical Biological Physics (2022)
      Cancer is a collection of related genetic diseases exhibiting uncontrolled cell growth that interferes with normal functioning of human organisms. It results from accumulation of unfavorable mutations in tissues. While the biochemical picture of how cancer appears is known, the molecular mechanisms of tumor formation remain not fully understood despite ...
    • Cancer-Associated Fibroblasts Induce a Collagen Cross-link Switch in Tumor Stroma 

      Pankova, Daniela; Chen, Yulong; Terajima, Masahiko; Schliekelman, Mark J.; Baird, Brandi N.; (2016)
      Intratumoral collagen cross-links heighten stromal stiffness and stimulate tumor cell invasion, but it is unclear how collagen cross-linking is regulated in epithelial tumors. To address this question, we used KrasLA1 mice, which develop lung adenocarcinomas from somatic activation of a KrasG12D allele. The lung tumors in KrasLA1 mice were highly ...
    • Cancer-Related NEET Proteins Transfer 2Fe-2S Clusters to Anamorsin, a Protein Required for Cytosolic Iron-Sulfur Cluster Biogenesis 

      (2015)
      Iron-sulfur cluster biogenesis is executed by distinct protein assembly systems. Mammals have two systems, the mitochondrial Fe-S cluster assembly system (ISC) and the cytosolic assembly system (CIA), that are connected by an unknown mechanism. The human members of the NEET family of 2Fe-2S proteins, nutrient-deprivation autophagy factor-1 (NAF-1) ...
    • Cannibalism and Infectious Disease: Friends or Foes? 

      Van Allen, Benjamin G.; Dillemuth, Forrest P.; Flick, Andrew J.; Faldyn, Matthew J.; Clark, David R.; (2017)
      Cannibalism occurs in a majority of both carnivorous and noncarnivorous animal taxa from invertebrates to mammals. Similarly, infectious parasites are ubiquitous in nature. Thus, interactions between cannibalism and disease occur regularly. While some adaptive benefits of cannibalism are clear, the prevailing view is that the risk of parasite ...
    • Cannibalism and Intraguild Predation Community Dynamics: Coexistence, Competitive Exclusion, and the Loss of Alternative Stable States 

      Toscano, Benjamin J.; Hin, Vincent; Rudolf, Volker H.W. (2017)
      Predators often exert strong top-down regulation of prey, but in many systems, juvenile predators must compete with their future prey for a shared resource. In such life-history intraguild predation (LHIGP) systems, prey can therefore also regulate the recruitment and thus population dynamics of their predator via competition. Theory predicts that ...
    • (Can’t Get No) Neighborhood Satisfaction? How Multilevel Immigration Factors Shape Latinos’ Neighborhood Attitudes 

      Schachter, Ariela; Sharp, Gregory; Kimbro, Rachel T. (2020)
      How does immigrant generation shape Latinos’ neighborhood attitudes? We extend theoretical frameworks focused on neighborhood attainment to explore how immigrant generation structures Latinos’ neighborhood satisfaction, particularly with respect to neighborhood immigrant composition. Using longitudinal data from the Los Angeles Family and Neighborhood ...
    • Capacity as Aggregation: Promises, Water and a Form of Collective Care in Northeast Brazil 

      Ballestero, Andrea (2017)
      As the twenty-first century gets underway, people have been experimenting with many forms of political organization. In Northeast Brazil, that experimental spirit led to the creation of the Water Pact, a process involving more than eight thousand participants through a series of public promise-making rituals in which they made pledges to care for ...
    • Captive Aerosol Growth and Evolution (CAGE) chamber system to investigate particle growth due to secondary aerosol formation 

      Sirmollo, Candice L.; Collins, Don R.; McCormick, Jordan M.; Milan, Cassandra F.; Erickson, Matthew H.; (2021)
      Environmental chambers are a commonly used tool for studying the production and processing of aerosols in the atmosphere. Most are located indoors and most are filled with air having prescribed concentrations of a small number of reactive gas species. Here we describe portable chambers that are used outdoors and filled with mostly ambient air. Each ...
    • Capture and Release of tRNA by the T-Loop Receptor in the Function of the T-Box Riboswitch 

      Fang, Xianyang; Michnicka, Malgorzata; Zhang, Yikan; Wang, Yun-Xing; Nikonowicz, Edward P. (2017)
      In Gram-positive bacteria, the tRNA-dependent T-box riboswitch system regulates expression of amino acid biosynthetic and aminoacyl-tRNA synthetase genes through a transcription attenuation mechanism. Binding of uncharged tRNA “closes” the switch, allowing transcription read-through. Structural studies of the 100-nucleotide stem I domain reveal tRNA ...
    • Capturing static and dynamic correlations by a combination of projected Hartree-Fock and density functional theories 

      (2013)
      This paper explores the possibility of combining projected Hartree-Fock and density functional theories for treating static and dynamic correlations in molecular systems with mean-field computational cost. The combination of spin-projected unrestricted Hartree-Fock (SUHF) with the TPSS correlation functional (SUHF+TPSS) yields excellent results for ...
