Using the data taken at the Pierre Auger Observatory between December 2004 and December 2012, we have examined the implications of the distributions of depths of atmospheric shower maximum (Xmax), using a hybrid technique, for composition and hadronic interaction models. We do this by fitting the distributions with predictions from a variety of hadronic interaction models for variations in the composition of the primary cosmic rays and examining the quality of the fit. Regardless of what interaction model is assumed, we find that our data are not well described by a mix of protons and iron nuclei over most of …

The electromagnetic polarizabilities of the nucleon are fundamental properties that describe its response to external electric and magnetic fields. They can be extracted from Compton-scattering data—and have been, with good accuracy, in the case of the proton. In contradistinction, information for the neutron requires the use of Compton scattering from nuclear targets. Here, we report a new measurement of elastic photon scattering from deuterium using quasimonoenergetic tagged photons at the MAX IV Laboratory in Lund, Sweden. These first new data in more than a decade effectively double the world data set. Their energy range overlaps with previous experiments and extends …

The Tragicomedy Of The Commons, Brigham Daniels

BYU Law Review

Scholarship on the commons focuses on a diverse set of problems, ranging from crashing fisheries to crowded court dockets. Because we find commons resources throughout our natural and cultural environments, understanding old lessons and learning new ones about the commons gives us leverage to address a wide range of problems. Because the list of resources identified as commons resources continues to grow, the importance of gleaning lessons about the commons will also continue to grow.

That being said, while the resources that make up the commons are certainly diverse, so too are the ways scholars depict it and the challenges …

Metalanguage In Carroll's "Jabberwocky" And Biggs's Reread, Asunción López-Varela

CLCWeb: Comparative Literature and Culture

In her article "Metalanguage in Carroll's 'Jabberwocky' and Biggs's reRead" Asunción López-Varela discusses Simon Biggs's installation reRead <http://www.littlepig.org.uk/reRead/reRead.htm> in relation to Lewis Carroll's poem. López-Varela posits that both works draw attention to the functioning of self-reflexive semiotic mechanisms present in human discourse and gestures. Based on the examples of the poem and the installation, López-Varela discusses how the human mind creates narratological coherence out of random and recursive patterns and argues that it does so by including other media which enable formats beyond the textual and the iconic. Further, López-Varela discusses how we are pre-disposed to process any semiotic …

Ecosystem Restoration On Santa Catalina Island: A Review Of Potential Approaches And The Promise Of Bottom-Up Invader Management, Denise A. Knapp

Monographs of the Western North American Naturalist

Restoring large, complex landscapes can be challenging, especially given that some threats to native diversity and ecological function cannot be wholly eliminated. Santa Catalina Island, California, provides a valuable case study because its challenges include a variety of ecosystem threats, legal restrictions, and cultural attachments, as well as a vocal resident human population that often does not agree with conservation actions. Catalina Island has been highly modified by numerous invasive species, fragmentation and erosion from roads, altered hydrology from dams, and increased fire frequency. In this paper, I build on a previously published review of resources and threats and discuss …

Texas Groundwater And Tragically Stable “Crossovers”, Zachary Bray

BYU Law Review

One recurring question in the academic literature on common-pool resources relates to the persistence of “tragic” commons regimes—systems that encourage, or at least tolerate, the inefficient, wasteful, hazardous, or unfair exploitation of a resource that is easily accessed for and diminished by individual use and consumption. Of course, not all commons are tragic: some common-pool resources invite individual access in efficient, fair, and durable ways. Yet many commonly held resources do lie under systems of governance that are not just tragic but persistently and stubbornly so. Often the tragic aspects of such commons regimes are well known; indeed, for some …

Isolated Wetland Commons And The Constitution, Blake Hudson, Mike Hardig

BYU Law Review

Isolated wetlands provide great ecological and economic value to the United States. While some states provide protection for isolated wetlands, a great many do not. These wetlands are also left outside the ambit of federal wetland regulatory protections under the Clean Water Act, with its murky jurisdictional reach. Notwithstanding jurisdictional questions under current federal statutes, the U.S. Supreme Court has gone so far as to call into question the constitutionality of federal isolated wetland regulation. This Article makes a normative argument that, in the absence of state or local programs providing holistic isolated wetland protection, federal action is needed. The …

Congenital Epidermoid Cyst Results In Muscle Fusion Defect In The Upper Lip, Fatih Dogan, Ibrahim Hakan Bucak

Materials Science and Engineering Faculty Research & Creative Works

Epidermoid cysts are rarely detected malformations in the oral cavity. Their development sites are the sublingual, submaxillary, and submandibular spaces. In this paper, we report a three-month-old infant who was admitted to our hospital due upper lip swelling. Magnetic resonance imaging showed that she had a two-centimeter cystic lesion and fusion defects of orbicularis oris muscle. The cyst was surgically removed, and histopathological diagnosis was “epidermoid cyst.” In recent literature, we could not find reports related to orbicularis oris muscle fusion defects because of epidermoid cyst.
