Weak cosmic censorship, dyonic Kerr-Newman black holes and Dirac fields
Creators: name: Toth, Gabor Zsolt
Publisher: name: arXiv
Year: 2015
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: It was investigated recently, with the aim of testing the weak cosmic censorship conjecture, whether an extremal Kerr black hole can be converted into a naked singularity by interaction with a massless classical Dirac test field, and it was found that this is possible. We generalize this result to electrically and magnetically charged rotating extremal black holes (i.e. extremal dyonic Kerr-Newman black holes) and massive Dirac test fields, allowing magnetically or electrically uncharged or nonrotating black holes and the massless Dirac field as special cases. We show that the possibility of the conversion is a direct consequence of the fact that the Einstein-Hilbert energy-momentum tensor of the classical Dirac field does not satisfy the null energy condition, and is therefore not in contradiction with the weak cosmic censorship conjecture. We give a derivation of the absence of superradiance of the Dirac field without making use of the complete separability of the Dirac equation in dyonic Kerr-Newman background, and we determine the range of superradiant frequencies of the scalar field. The range of frequencies of the Dirac field that can be used to convert a black hole into a naked singularity partially coincides with the superradiant range of the scalar field. We apply horizon-penetrating coordinates, as our arguments involve calculating quantities at the event horizon. We describe the separation of variables for the Dirac equation in these coordinates, although we mostly avoid using it.

description: Second semester University: Panteion University, Athens
description: Raising the defence of duress for crimes against humanity and war crimes has always been contentious due to the tense relationship between law and morality. It poses serious philosophical, moral and legal challenges as it requires the judge to balance the accused life against the victims’. “How can a judge satisfy himself that the death of one person is the lesser evil that the death of another?” While the defence of duress is a well-established defence, substance of the defence under the Rome Statute is still rather elusive and ambiguous. This thesis aims to examine whether the current standard of duress under the Rome Statute reflects the realities of individuals experiencing duress. This thesis will analyse the criteria for a duress claim to succeed, the shortfalls of the current standard under the Rome Statute and balance the defendant’s justice with the wider goal of international criminal law.
Comparison of Reliable Change Indices of CNS Vital Signs for Different Ranges of Baseline Scores
Creators: name: Ikoma, Michelle M.

description: Computerized neurocognitive tests are widely used in the management of sport-related concussion. Many of these assessments use reliable change confidence intervals—computed as baseline score ± reliable change index (RCI)—to classify an individual as impaired or unimpaired at a follow-up test point. If an individual’s retest score falls outside of the reliable change confidence interval on a given domain, he or she is classified as impaired on that domain. The purpose of this study was to compare RCIs for three different ranges of CNS Vital Signs baseline scores: the lowest quintile (0-20th percentile), middle quintile (40-60th percentile), and highest quintile (80-100th percentile). One-hundred seven Division I student-athletes completed baseline and follow-up computerized neurocognitive testing on CNS Vital Signs and were divided into quintile groups based on their baseline score for each clinical domain. RCIs were computed for the lowest, middle, and highest quintiles for each domain. Overall group RCIs were also computed. The RCIs varied considerably across the quintile groups, with average and high baseline performers tending to have smaller RCIs than low baseline performers and the full group in each domain. In addition, significant interaction effects of time and quintile group were found for several domains as well as for Neurocognition Index. These results suggest that it is important for clinicians to consider an individual’s baseline performance level when interpreting CNS Vital Signs neurocognitive test results using a baseline/post-injury comparison model.

description: James Taggart developed the sketch recognition system HUNCH at MIT in 1972. Rather than the user trying to understand the software in order to progress a drawing, in the case of HUNCH, the software observed the user sketching. It enabled a conversation between user and software through the sketch as a medium. HUNCH was one component of the Architecture Machine, created in the Architecture Machine Group (Arch Mac), run by Nicholas Negroponte at MIT between 1967 and 1985 and a brainchild of cross-fertilization between architecture, computer sciences and cybernetics in the early 1970s. One of HUNCHs objectives was to enable even the layman to ‘design’ a dream home. The paper presents HUNCH’s concept as AI-equipped ‘partner’ for the architect, designer or layman.

HUNCH war eine Komponente der Architecture Machine, die in der Architecture Machine Group (Arch Mac) entwickelt wurde, die von Nicholas Negroponte am MIT zwischen 1967 und 1985 geleitet wurde und in den frühen 1970er Jahren eine Idee der gegenseitigen Befruchtung zwischen Architektur, Informatik und Kybernetik war. Eines der Ziele von HUNCH war es, auch dem Laien zu ermöglichen, ein Traumhaus zu "gestalten". Das Papier stellt das Konzept von HUNCH als KI-gestützter "Partner" für den Architekten, Designer oder Laien vor.

description: Since the last expansion of the Schengen area with the incorporation of Switzerland on December 2008 and Liechtenstein in 2011, the Schengen Agreement has been accumulating supporters and detractors regarding the free movement of persons. But, is it really a free movement of persons agreement? Or a free movement of privileged nationalities which switches in accordance to markets and political agreements? How does the Schengen border code affect third-country nationals? This thesis wants to expose how the Schengen Agreement affects third-country nationals human rights from the starting point of applying for a Schengen visa, until crossing the Schengen border. First, it analyses freedom of movement as a human right and its universality. Second, it discusses the common rules regarding the issuance of a Schengen visa (Visa Code) and the Common Consular Instructions, focusing on whether its implementation is really common or particular, universal or relative. And finally, it tries to clear up and examine if the Schengen acquis is in crisis, and it shows how the Schengen countries are emphasizing security more than human rights. The final questions are, when it comes to the implementation of the Schengen acquis, how do consular practices affect its application? Since Schengen countries consider themselves defender of human rights, does the implementation of the Schengen acquis really respect human rights?
Recent results of cosmic-ray studies with IceTop at the IceCube Neutrino

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: The IceCube Neutrino Observatory is a cubic-kilometer Cherenkov detector that is deployed deep in the Antarctic ice at the South Pole. A square kilometer companion surface detector, IceTop, located directly above in the in-ice array, measures cosmic-ray initiated extensive air showers with primary energies between 100 TeV and 1 EeV. By combining the events measured by IceTop and the in-ice detectors of IceCube in coincidence, we can reconstruct the energy spectra for different primary mass groups. Therefore, we provide information about the origin of cosmic rays, in particular, in the transition region from galactic to extra-galactic origin of high-energy cosmic rays. In this contribution we present recent experimental results, as well as prospects by the foreseen enhancement of the surface detectors of IceTop and the future IceCube-Gen2 surface array.

 Notes:— In the protologue of K. tucumanensis, the authors cited as holotype the specimen Lourteig & O’Donell s.n. [LIL2855]. However, four well conserved specimens with the number 2855 were found in LIL (LIL 000675, LIL000676, LIL000677, LIL 000678). All specimens catalogued as holotypes, and all with the information found in the protologue. To avoid misinterpretation, the specimen LIL000675 is designated here as lectotype because this is well preserved and has plenty of material to study the species.

Characterize the Dynamic Tertiary Interaction that Promotes Cleavage in an Extended Hammerhead Ribozyme
Creators: name: Mac, Quoc
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Recent bioinformatics studies have revealed the ubiquitous presence of hammerhead ribozyme, a small self-cleaving RNA, in all domains of life, from bacteria to complex eukaryotes. Their fundamental catalytic activity as well as genomic locations suggest some important biological functions, especially in gene regulation. While a minimal hammerhead’s catalytic core is essential for cleavage activity, the presence of transient tertiary interactions between stem I and stem II of the extended hammerhead helps to enhance cleavage by up to 1000 fold. In this study, we have attempted to study the dynamic tertiary interaction of c10orf118 hammerhead ribozyme, a highly-conserved ribozyme in mammalian species. While it has been suggested that a pseudoknot interaction helps to bring the top two stems together to stabilize the catalytic core, we hypothesized that this interaction is in fact facilitated by base pair formation within the loop of stem II and the bulge of stem I. By using chemical exchange saturation transfer (CEST), a recently developed NMR dynamics experiment, we were able to detect the presence of an excited state with population of only 0.9%. Conversely, this excited state was not observed in three other control constructs in which the proposed interactions were perturbed. From this evidence, we concluded that that during its catalytic pathway, the c10orf118 hammerhead ribozyme samples a rare state that is stabilized by specific loop-bulge interactions between stem I and stem II.

 Notes:— According to Stafleu & Cowan (1979) Spegazzini’s type specimens were deposited at LP. Only one L. ameghinoi specimen in LP (barcode LP006751!) was collected in the Golfo of San Jorge by C. Ameghino s.n., but the collection date (January 1896) does not match the information in the protologue. No other specimen from LP matched the original description, so it is presumed that the holotype is missed. A specimen found in CORD (CORD 00003022) is designated here as lectotype because coincides with the protologue. However, the plant material present on this specimen is not sufficient for diagnostic purposes because the specimen consists of only a few leaves (Art. 9.8; McNeill et al. 2012). Thus, the specimen Biganzoli & Larsen 1953 (SI 092511) is designated here as an epitype. This specimen consists of a complete plant with flowers and fruits, very well preserved and collected in the same region as mentioned in the protologue (Fig. 3).

Interactions of $ω$-Mesons in Nuclear Matter and with Nuclei
Creators: name: Lenske, Horst
Publisher: name: arXiv
Year: 2023
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: In--medium interactions of $ω$--mesons are investigated microscopically by coupling to $NN^{-1}$ and $N^*N^{-1}$ particle--hole excitations of the medium, including elativistic mean--field dynamics by self--consistent scalar and vector fields. The resulting self--energies are transmitted to finite nuclei in local density approximation. Real and imaginary parts of longitudinal and transversal self--energies are discussed. The relation of the present approach to meson cloud models is addressed and an ambiguity is pointed out. Applications to recent data on the in--medium width of $ω$ mesons scattered on a Niobium target serve to determine unknown $N^*Nω$ in-medium coupling constants. The data are well described by $N^*N^{-1}$ self--energies containing S--wave and P--wave $N^*$ resonances. Exploratory investigations, however, show that the spectroscopic composition of self--energies depends crucially on the near--threshold properties of the width which at present is known only within large error bars. The calculations predict the prevalence of transversal self--energies, implying that vector current conservation is still maintained in the nuclear medium by slightly more than 90\%. Schrödinger--equivalent potentials are derived and scattering lengths and effective range parameters are extracted for the longitudinal and transversal channel. Longitudinal and transversal spectral distributions are discussed and the dependencies on momentum and nuclear density are investigated. Schrödinger--type $ω+{}^{93}$Nb optical potentials are constructed. Low--energy parameters are determined, are used to study the pole structure of the S--matrix at threshold. The effective range expansion of the omega--nucleus K--matrix led to a $ω+{}^{93}$Nb bound states with binding energy $Re(\varepsilon_B)=-448$~keV but of width $Γ_B=4445$~keV.

description: Cavity-based large scale quantum information processing (QIP) may involve multiple cavities and require performing various quantum logic operations on qubits distributed in different cavities. Geometric-phase-based quantum computing has drawn much attention recently, which offers advantages against inaccuracies and local fluctuations. In addition, multiqubit gates are particularly appealing and play important roles in QIP. We here present a simple and efficient scheme for realizing a multi-target-qubit unconventional geometric phase gate in a multi-cavity system. This multiqubit phase gate has a common control qubit but different target qubits distributed in different cavities, which can be achieved using a single-step operation. The gate operation time is independent of the number of qubits and only two levels for each qubit are needed. This multiqubit gate is generic, e.g., by performing single-qubit operations, it can be converted into two types of significant multi-target-qubit phase gates useful in QIP and quantum Fourier transform. The proposal is quite general, which can be used to accomplish the same task for a general type of qubits such as atoms, NV centers, quantum dots, and qubits.

Directed Evolution of Adeno-associated Virus Targeting Heart and Skeletal muscle
Creators: name: Xu, Vivian
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The goal of this project is to engineer gene vectors that target a single tissue type,
especially striated muscles. A random library of adeno-associated virus (AAV) was constructed
by shuffling the capsid genes of AAV serotypes 1 to 9, and the resulting chimeric genes were
screened for muscle specificity by direct in vivo panning. Viruses expressed high in muscles
were collected, and the process was repeated to construct chimeric AAV library. To further
improve specificity, in vitro biopanning was done on three types of cultured cells that represent
kidney, liver and muscles. For the desirable features, selection was based on infection rate,
preferably high in muscle but low in liver. Using AAV2 as a standard, three reconstructed AAV
were found to be expressed at higher frequencies in myotubes with comparable or lower
frequencies in hepatocytes. These recombined AAV would be further selected in vivo through
tail vein injection in mice to identify the virus that was the most specific to muscles.
Secure Expansion of Energy Storage and Transmission Lines Considering Bundling Option Under Renewable Penetration

description: This paper presents a multi-stage expansion model for the co-planning of transmission lines, battery energy storage (ES), and wind power plants (WPP). High penetration of renewable energy sources (RES) is integrated into the proposed model concerning renewable portfolio standard (RPS) policy goals. The possibility of bundling existing transmission lines to uprate power flow capacity is considered. Renewable energy curtailment and load shedding are included in the model to assess the system operation more precisely. Battery ES devices are co-planned to defer transmission expansion and renewable management. To make the time complexity of the problem tractable and capture the uncertainties of load and RES in an hourly resolution, a chronological time-period clustering algorithm is used to extract the representative hours of each planning stage. Additionally, the flexible ramp reserve is utilized to handle the uncertainty of RES. An accelerated Benders dual decomposition (BDD) algorithm is developed to solve the proposed model mixed-integer linear programming (MILP) formulation. The N-1 security criterion is evaluated by considering a designed contingency screening (CS) algorithm to identify higher risk contingencies. The effectiveness of the proposed co-planning model is evaluated using IEEE RTS 24-bus and IEEE 118-bus test systems.

description: Evidence for small amounts of very hot plasma has been found in active regions and might be the indication of an impulsive heating, released at spatial scales smaller than the cross section of a single loop. We investigate the heating and substructure of coronal loops in the core of one such active region by analyzing the light curves in the smallest resolution elements of solar observations in two EUV channels (94 A and 335 A) from the Atmospheric Imaging Assembly on-board the Solar Dynamics Observatory. We model the evolution of a bundle of strands heated by a storm of nanoflares by means of a hydrodynamic 0D loop model (EBTEL). The light curves obtained from the random combination of those of single strands are compared to the observed light curves either in a single pixel or in a row of pixels, simultaneously in the two channels and using two independent methods: an artificial intelligent system (Probabilistic Neural Network, PNN) and a simple cross-correlation technique. We explore the space of the parameters to constrain the distribution of the heat pulses, their duration and their spatial size, and, as a feedback on the data, their signatures on the light curves. From both methods the best agreement is obtained for a relatively large population of events (1000) with a short duration (less than 1 min) and a relatively shallow distribution (power law with index 1.5) in a limited energy range (1.5 decades). The feedback on the data indicates that bumps in the light curves, especially in the 94 A channel, are signatures of a heating excess that occurred a few minutes before.

description: Heusler ferromagnetic shape-memory alloys (FSMAs) normally consist of transition-group d-metals and main-group p-elements. Here, we report the realization of FSMAs in Heusler phases that completely consist of d metals. By introducing the d-metal Ti into NiMn alloys, cubic B2-type Heusler phase is obtained and the martensitic transformation temperature is decreased efficiently. Strong ferromagnetism is established by further doping Co atoms into the B2-type antiferromagnetic Ni-Mn-Ti austenite. Based on the magnetic-field-induced martensitic transformations, collective multifunctional properties are observed in Ni(Co)-Mn-Ti alloys. The d metals not only facilitate the formation of B2-type Heusler phases, but also establish strong ferromagnetic coupling and offer the possibility to tune the martensitic transformation.

In Person Assisters:  Lessons Learned from Enrolling the Uninsured in North Carolina
Creators: name: Holtzman, Rachel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Confusion about the ACA’s coverage provisions underscores the importance of outreach
and enrollment. Successful efforts are crucial if the ACA is to meet its projected target for
covering the uninsured. Due to their widespread unfamiliarity with the health insurance
marketplaces, more than half of (60%) uninsured individuals report that they want personalized
help navigating the new online system.10 The federal government has established in person
assistance programs2 to identify, educate, and assist consumers with enrollment into the new
health insurance marketplaces. These in person assistors (IPAs) include Navigators, Certified
Application Counselors, and Non-Navigator Assistance Personnel. They receive training by the
state and/or federal government to help the uninsured enroll through the marketplace and will
need to implement a variety of strategies in order to help enroll the uninsured.
Although IPAs will play a central role in new enrollment efforts, not much is known on
best enrollment practices for the marketplaces. While policy makers and IPAs can learn key
lessons from previous enrollment efforts conducted in Massachusetts in 2006, and nationwide for
Children’s Health Insurance Program (CHIP) and Medicaid, it is unclear which practices will
prove most effective for enrolling the uninsured through the ACA. As ACA enrollment efforts
move forward, it will be important to both document and analyze the enrollment experience of
IPAs.
Given the importance of IPAs to ACA implementation, this study aims to explore the role
that IPAs play in enrolling the uninsured across the state. This research will use semi-structured

description: The van Leeuwen proof of linear-response time-dependent density functional theory (TDDFT) is generalized to thermal ensembles. This allows generalization to finite temperatures of the Gross-Kohn relation, the exchange-correlation kernel of TDDFT, and fluctuation dissipation theorem for DFT. This produces a natural method for generating new thermal exchange-correlation (XC) approximations.

description: Most democratic countries use election methods to transform election results into whole numbers which usually give the number of seats in a legislative body the parties obtained. Which election method does this best can be specified by measuring the error between the allocated result and the ideal proportion. We show how to find an election method which is best suited to a given error function. We also discuss several properties of election methods that have been labelled paradoxa. In particular we explain the highly publicised ``Alabama'' Paradox for the Hare/Hamilton method and show that other popular election methods come with their very own paradoxa.

Impact of Human Provisioning from the Chatham Fish Pier on the Ecology of Grey Seals (Halichoerus Grypus)
Creators: name: Voorhis, Rachel R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Human provisioning (feeding) of otherwise wild animals has been shown to significantly alter
their body condition and behavior as compared to other members of the population. However, the vast
majority of these studies tends to focus on either physiology or behavior, and thus do not provide a
holistic assessment of the impact of provisioning. The recent population boom of grey seals (Halichoerus
grypus) in the western Atlantic and their proximity to humans makes them an ideal candidate for such a
study. Morphological data was collected and GPS tags deployed for several seals in Chatham Harbor,
Massachusetts in June 2013. Movement analysis suggested one seal was provisioned via the Chatham
Fish Pier, and the assumption was later verified by photo identification. The provisioned female (#709)
was particularly small in terms of length, weight and girth for her age, and exhibited significantly
decreased blubber thickness compared to other female seals in the study. Stable isotope analysis
determined that #709 was foraging (or was fed) prey items from a higher tropic level than normal, as
well as indicated high levels of inshore feeding. Home range, trip and behavioral analysis generated by
GPS tag data suggest that the provisioned seal deviated from ‘normal’ patterns of movement including
number, location and length of foraging trips, home range size and location, and breeding behavior. The
cumulative analysis is limited by a small sample size, but implies that further research of this type could
support a direct link between human provisioning and significant deviations in grey seal ecology.

description: An abstract property (H) is the key to a complete a priori error analysis in the (discrete) energy norm for several nonstandard finite element methods in the recent work [Lowest-order equivalent nonstandard finite element methods for biharmonic plates, Carstensen and Nataraj, M2AN, 2022]. This paper investigates the impact of (H) to the a posteriori error analysis and establishes known and novel explicit residual-based a posteriori error estimates. The abstract framework applies to Morley, two versions of discontinuous Galerkin, $C^0$ interior penalty, as well as weakly over-penalized symmetric interior penalty schemes for the biharmonic equation with a general source term in $H^{-2}(Ω)$.

description: In the last few decades, knowledge organization systems (KOS), especially thesauri,
 classification schemes and lists of subject headings, have largely followed or conformed
 with the established data models defined by standards, recommendations or best practices.
 This long list contains some widely used models, such as ISO5964 Part 1, ISO2788, Z39.19,
 BS 5723 and BS 6723, (Dextre Clarke, 2008) IFLA Principles Underlying Subject Heading
 Languages (SHLs), and MARC 21 Format for Classification Data.
 The FRSAD (Functional Requirements for Subject Authority Data) conceptual model is the third member of the FRBR family, developed under the auspices of IFLA. The report was approved in 2010 and will be published in 2011. FRSAD is a general conceptual model that focuses on the subject relationship and therefore provides a theoretical framework for all KOS and their data models. In addition, it also assists in the assessment of the potential for international sharing and (re)use of subject authority data both within the library sector and beyond.
 In this paper FRSAD is compared to SKOS and SKOS XL as data models (with implementation examples).
Magnetic field induced anisotropy of $^{139}\mathrm{La}$ spin-lattice relaxation rates in stripe ordered ${\mathrm{La}}_{1.875}{\mathrm{Ba}}_{0.125}{\mathrm{CuO}}_{4}$

description: We report $^{139}$La nuclear magnetic resonance studies performed on a La$_{1.875}$Ba$_{0.125}$CuO$_4$ single crystal. The data show that the structural phase transitions (high-temperature tetragonal $\rightarrow$ low-temperature orthorhombic $\rightarrow$ low-temperature tetragonal phase) are of the displacive type in this material. The $^{139}$La spin-lattice relaxation rate $T_1^{-1}$ sharply upturns at the charge-ordering temperature $T_\text{CO}$ = 54 K, indicating that charge order triggers the slowing down of spin fluctuations. Detailed temperature and field dependencies of the $T_1^{-1}$ below the spin-ordering temperature $T_\text{SO}$ = 40 K reveal the development of enhanced spin fluctuations in the spin-ordered state for $H \parallel [001]$, which are completely suppressed for large fields along the CuO$_2$ planes. Our results shed light on the unusual spin fluctuations in the charge and spin stripe ordered lanthanum cuprates.

Ousting Social Orthodoxy and Instituting Teenager Control: The Young Adult Coup d'état for Representation in Hinton's Modern Classic
Creators: name: Farrington, Lauren
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This paper follows Ponyboy Curtis' deconstruction of identity in S.E. Hinton’s novel The Outsiders and asks the question "what does it mean to be an outsider?” The teenagers of The Outsiders are split into “haves” and “have-nots”—each group an outsider to the experience of the other. This “haves”/”have-not” binary is heralded by the orthodox of the community—adults—and perpetuated by teenagers who do not necessarily agree with the binary, but who do not know how to break free. Hinton presents a model for teenagers to follow in order to practically create representation and justice for themselves. Teenagers must reject the false impositions of identity and teenage reality projected by orthodoxy, and then teenagers must take responsibility for their own reality. The impact of The Outsiders on literary history is an example of success using Hinton’s model. Initially labeled an outsider by literary elites because of its adolescent story and teenage authorship, Hinton’s confidence in her novel’s attitude and message led to widespread popularity, awards, and eventual acceptance and representation of young adults in canonical literature.

description: If $X$ is a geodesic metric space and $x_1,x_2,x_3\in X$, a geodesic triangle $T=\{x_1,x_2,x_3\}$ is the union of the three geodesics $[x_1x_2]$, $[x_2x_3]$ and $[x_3x_1]$ in $X$. The space $X$ is $δ$-hyperbolic (in the Gromov sense) if any side of $T$ is contained in a $δ$-neighborhood of the union of the two other sides, for every geodesic triangle $T$ in $X$. The study of hyperbolic graphs is an interesting topic since the hyperbolicity of a geodesic metric space is equivalent to the hyperbolicity of a graph related to it. In the context of graphs, to remove and to contract an edge of a graph are natural transformations. The main aim in this work is to obtain quantitative information about the distortion of the hyperbolicity constant of the graph $G \setminus e$ (respectively, $\,G/e\,$) obtained from the graph $G$ by deleting (respectively, contracting) an arbitrary edge $e$ from it. This work provides information about the hyperbolicity constant of minor graphs.
Retrospective comparison of outcomes in patients with recurrent or refractory ovarian cancer treated with pegylated liposomal doxorubicin at an academic medical center
Creators: name: Shen, Eric
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Pegylated liposomal doxorubicin, or PLD, is a widely used agent in
treating recurrent and refractory ovarian cancer. The brand name drug, Doxil®
was the first FDA-approved PLD product used in the United States. In 2012,
Doxil® supply issues prompted the FDA to approve the emergency importation of
Lipodox™, which then was not FDA-approved, as an alternative to Doxil®,
despite little data existing comparing the equivalency of the two. UNC Medical
Center (UNCMC) has treated patients using both products based on availability.
Due to the nuanced nature of liposomal drug products and the limited data
concerning the therapeutic equivalency of these two drugs, outcomes of ovarian
cancer patients treated with Lipodox™ were compared to those treated with
Doxil®. This retrospective comparison suggests that the Doxil® drug shortage did
not result in differences in patient outcomes when Lipodox™ was used as a
monotherapy for relapsed and refractory ovarian cancer.
title: Elements of being: Reading Plato’s Theaetetus and Sophist as a critique of Wittgenstein’s Tractatus Logico-Philosophicus
Creators: name: Manning, Lucy Fay
Publisher: name: The Open University
Year: 2023

description: In his Philosophical Investigations, Wittgenstein suggests that the logical atoms of his Tractatus Logico-Philosophicus are similar to the primary elements of Socrates’ Dream in Plato’s Theaetetus (P.I. §46). I explore the texts in detail and argue that there are two key similarities between the Tractatus and the Dream: they both propose the existence of a single type of logical ‘atom’ and they both reject the object-property distinction. I suggest that Plato’s Theaetetus and Sophist are effectively two parts of one larger dialogue which can be read as a critique of Tractatus-type theories – theories that have object-only ontologies. I argue that Plato demonstrates that any theory lacking the object-property distinction will be unable to explain how strings of words are transformed into meaningful propositions about the world. Such theories relegate all propositions and mathematics to the class of nonsense. Wittgenstein acknowledges that, strictly speaking, the propositions of the Tractatus are nonsense (TLP 6.54); I show that the inexpressibility problem that Wittgenstein references is the same problem that Plato shows is faced by Heraclitus in the Theaetetus (183b). At the time of writing the Tractatus, Wittgenstein did not realise that all propositions, not just those of philosophy, like those in the Tractatus, were reduced to nonsense by his theory. Plato, on the other hand, foresaw the issues that any Tractatus-type theory would inevitably face, and resolved them in the Sophist with the introduction of a second type of logical atom with a different (metaphorical) shape. Different shapes account for how logical atoms combine to create propositions with unity. I argue that the version of logical atomism that Plato presents in the Sophist looks more Fregean than Tractarian. I discuss Wittgenstein’s criticism of Frege, rejection of the idea of a second type of atom representing properties, and preference for necessarily featureless atoms. I conclude that this preference comes at too high a price.
