The Pursuit of Happiness

Perfection, it is the expectation perpetuated by mass media. We are spoon-fed the propaganda of the American Dream through sex-filled advertisements of beer and food our entire lives. Anything less than a god-fearing nuclear family eating three square name-brand meals a day and wearing the newest clothes is seen as a moral failing. We willingly participate in the capitalist game of conformity, it doesn’t have to be policed, only continually advertised. How far can this go until it becomes a cult mindset? And does any of this actually equate to happiness? I am depicting a “fictional” world where social conformity has become a cult practice, representing the visual culture and values of mass media within it. The figures in my paintings are set in liminal environments where they interact with symbols like the smiley face, which acts as logo and figurehead of the cult, in these spaces they wrestle with their perceptions of themselves, their mental health, and the cult. The imagery all relates to the “sex, drugs, and money” mindset valued by the media, as well as party culture. This party imagery is really key to the work because partying is not only valued as a form of conformity that often perpetuates an environment of self-medication but it is also a form of escapism for the figures. They battle between letting go in the only way they know how and being confronted by the ever-present subconsciously ingrained cult pressures. I critique the outcomes of our capitalist, consumerist society by exploring the materials and symbols commonly found within it. The wearable pieces use plastic and some readymade items to comment on the value we hold of those materials. A few of the pieces represent how an oppressive society could even make oppression or addiction opulent and visible on the body. I work from personal experience. When constantly flooded with new information from brands, ads, T.V., music, social media, and just people with their general opinions this “mind pollution” has to find its way out as new imagery. I’m interested in how we fit ourselves into the narrative around this overwhelming amount of information and the pressure to somehow agree with it all.https://digitalcommons.murraystate.edu/art498/1073/thumbnail.jp

Properties of nitrogen-vacancy centers in diamond: group theoretic approach

We present a procedure that makes use of group theory to analyze and predict the main properties of the negatively charged nitrogen-vacancy (NV) center in diamond. We focus on the relatively low temperatures limit where both the spin-spin and spin-orbit effects are important to consider. We demonstrate that group theory may be used to clarify several aspects of the NV structure, such as ordering of the singlets in the ($e^2$) electronic configuration, the spin-spin and the spin-orbit interactions in the ($ae$) electronic configuration. We also discuss how the optical selection rules and the response of the center to electric field can be used for spin-photon entanglement schemes. Our general formalism is applicable to a broad class of local defects in solids. The present results have important implications for applications in quantum information science and nanomagnetometry.Comment: 30 pages, 6 figure

The negatively charged nitrogen-vacancy centre in diamond: the electronic solution

The negatively charged nitrogen-vacancy centre is a unique defect in diamond that possesses properties highly suited to many applications, including quantum information processing, quantum metrology, and biolabelling. Although the unique properties of the centre have been extensively documented and utilised, a detailed understanding of the physics of the centre has not yet been achieved. Indeed there persists a number of points of contention regarding the electronic structure of the centre, such as the ordering of the dark intermediate singlet states. Without a sound model of the centre's electronic structure, the understanding of the system's unique dynamical properties can not effectively progress. In this work, the molecular model of the defect centre is fully developed to provide a self consistent model of the complete electronic structure of the centre. The application of the model to describe the effects of electric, magnetic and strain interactions, as well as the variation of the centre's fine structure with temperature, provides an invaluable tool to those studying the centre and a means to design future empirical and ab initio studies of this important defect.Comment: 24 pages, 6 figures, 10 table

Status of Coral Reefs in the US Caribbean and Gulf of Mexico: Florida, Texas, Puerto Rico, US Virgin Islands and Navassa

The following report on the status of US Caribbean coral reef ecosystems has been summarised from more extensive reports submitted to the US Coral Reef Task Force (USCRTF) working group that implemented in 2000 ‘A National Program to Assess, Inventory, and Monitor US Coral Reef Ecosystems’. The more-lengthy reports are also the basis for the biennial-issued document, ‘Status and Trends of US Coral Reef Ecosystems’. Each author is a recognised technical expert with responsibility for monitoring and/or managing aspects of their respective coral reef ecosystems

Evaluation of machine-learning methods for ligand-based virtual screening

Machine-learning methods can be used for virtual screening by analysing the structural characteristics of molecules of known (in)activity, and we here discuss the use of kernel discrimination and naive Bayesian classifier (NBC) methods for this purpose. We report a kernel method that allows the processing of molecules represented by binary, integer and real-valued descriptors, and show that it is little different in screening performance from a previously described kernel that had been developed specifically for the analysis of binary fingerprint representations of molecular structure. We then evaluate the performance of an NBC when the training-set contains only a very few active molecules. In such cases, a simpler approach based on group fusion would appear to provide superior screening performance, especially when structurally heterogeneous datasets are to be processed

Copper-nickel-rich, amalgamated ferromanganese crust-nodule deposits from Shatsky Rise, NW Pacific

A unique set of ferromanganese crusts and nodules collected from Shatsky Rise (SR), NW Pacific, were analyzed for mineralogical and chemical compositions, and dated using Be isotopes and cobalt chronometry. The composition of these midlatitude, deep-water deposits is markedly different from northwest-equatorial Pacific (PCZ) crusts, where most studies have been conducted. Crusts and nodules on SR formed in close proximity and some nodule deposits were cemented and overgrown by crusts, forming amalgamated deposits. The deep-water SR crusts are high in Cu, Li, and Th and low in Co, Te, and Tl concentrations compared to PCZ crusts. Thorium concentrations (ppm) are especially striking with a high of 152 (mean 56), compared to PCZ crusts (mean 11). The deep-water SR crusts show a diagenetic chemical signal, but not a diagenetic mineralogy, which together constrain the redox conditions to early oxic diagenesis. Diagenetic input to crusts is rare, but unequivocal in these deep-water crusts. Copper, Ni, and Li are strongly enriched in SR deep-water deposits, but only in layers older than about 3.4 Ma. Diagenetic reactions in the sediment and dissolution of biogenic calcite in the water column are the likely sources of these metals. The highest concentrations of Li are in crust layers that formed near the calcite compensation depth. The onset of Ni, Cu, and Li enrichment in the middle Miocene and cessation at about 3.4 Ma were accompanied by changes in the deep-water environment, especially composition and flow rates of water masses, and location of the carbonate compensation depth. Key Points - Fe-Mn crusts can have a diagenetic component - Mid-latitude N. Pacific deep-water Fe-Mn crusts are uniquely enriched in Cu, Th, Li - Temporal changes in deep-ocean geochemical processes are recorde
