description: We show that little string theory on S^5 can be obtained as double-scaling limits of the maximally supersymmetric Yang-Mills theories on RxS^2 and RxS^3/Z_k. By matching the gauge theory parameters with those in the gravity duals found by Lin and Maldacena, we determine the limits in the gauge theories that correspond to decoupling of NS5-brane degrees of freedom. We find that for the theory on RxS^2, the 't Hooft coupling must be scaled like ln^3(N), and on RxS^3/Z_k, like ln^2(N). Accordingly, taking these limits in these field theories gives Lagrangian definitions of little string theory on S^5.

description: We perform an extensive analysis of the statistics of axion masses and interactions in compactifications of type IIB string theory, and we show that black hole superradiance excludes some regions of Calabi-Yau moduli space. Regardless of the cosmological model, a theory with an axion whose mass falls in a superradiant band can be probed by the measured properties of astrophysical black holes, unless the axion self-interaction is large enough to disrupt formation of a condensate. We study a large ensemble of compactifications on Calabi-Yau hypersurfaces, with $1 \leq h^{1,1} \leq 491$ closed string axions, and determine whether the superradiance conditions on the masses and self-interactions are fulfilled. The axion mass spectrum is largely determined by the Kähler parameters, for mild assumptions about the contributing instantons, and takes a nearly-universal form when $h^{1,1} \gg 1$. When the Kähler moduli are taken at the tip of the stretched Kähler cone, the fraction of geometries excluded initially grows with $h^{1,1}$, to a maximum of $\approx 0.5$ at $h^{1,1} \approx 160$, and then falls for larger $h^{1,1}$. Further inside the Kähler cone, the superradiance constraints are far weaker, but for $h^{1,1} \gg 100$ the decay constants are so small that these geometries may be in tension with astrophysical bounds, depending on the realization of the Standard Model.

description: Despite abundant negotiation strategies in literature, the complexity of automated negotiation forbids a single strategy from being dominant against all others in different negotiation scenarios. To overcome this, one approach is to use mixture of experts, but at the same time, one problem of this method is the selection of experts, as this approach is limited by the competency of the experts selected. Another problem with most negotiation strategies is their incapability of adapting to dynamic variation of the opponent's behaviour within a single negotiation session resulting in poor performance. This work focuses on both, solving the problem of expert selection and adapting to the opponent's behaviour with our Autonomous Negotiating Agent Framework. This framework allows real-time classification of opponent's behaviour and provides a mechanism to select, switch or combine strategies within a single negotiation session. Additionally, our framework has a reviewer component which enables self-enhancement capability by deciding to include new strategies or replace old ones with better strategies periodically. We demonstrate an instance of our framework by implementing maximum entropy reinforcement learning based strategies with a deep learning based opponent classifier. Finally, we evaluate the performance of our agent against state-of-the-art negotiators under varied negotiation scenarios.

description: Metric of axially symmetric asymptotically flat black holes in an arbitrary metric theory of gravity can be represented in the general form which depends on infinite number of parameters. We constrain this general class of metrics by requiring the existence of additional symmetries, which lead to the separation of variables in the Hamilton-Jacobi and Klein-Gordon equations, and show that once the metric functions change sufficiently moderately in some region near the black hole, the black-hole shadow depends on a few deformation parameters only. We analyze the influence of these parameters on the black-hole shadow. We also show that the shadow of the rotating black hole in the Einstein-dilaton-Gauss-Bonnet theory is well approximated if the terms violating the separation of variables are neglected in the metric.

description: Diagrammatic, analogical or iconic representations are often contrasted with linguistic or logical representations, in which the shape of the symbols is arbitrary. The aim of this paper is to make a case for the usefulness of diagrams in inferential knowledge representation systems. Although commonly used, diagrams have for a long time suffered from the reputation of being only a heuristic tool or a mere support for intuition. The first part of this paper is an historical background paying tribute to the logicians, psychologists and computer scientists who put an end to this formal prejudice against diagrams. The second part is a discussion of their characteristics as opposed to those of linguistic forms. The last part is aimed at reviving the interest for heterogeneous representation systems including both linguistic and diagrammatic representations.

description: Thermodynamics of $z=4$ Hořava-Lifshitz black holes in 3+1 dimensions is studied in extended phase space. By using the scaling argument we find the Smarr relation and the first law for the black hole solutions of $z=4$ Hořava-Lifshitz gravity. We find that it is necessary to take into account the variation of dimensionful parameters of the theory in the first law. We find that the reverse isoperimetric inequality can be violated for spherical, flat, and hyperbolic horizons and in all such cases we have black holes for which the specific heat at constant pressure and volume are positive. This provides a counterexample to a recent conjecture stating that black holes violating the reverse isoperimetric inequality are thermodynamically unstable. We find for $z=4$ Hořava-Lifshitz black holes with hyperbolic horizons that there are two critical points: one showing Van der Waals behavior, the other reverse Van der Waals behavior.

In addition to the literary value inherent in Cervantes’s last work Los trabajos de Persiles y Segismunda, the short stories intercalated in the novel that constitute our corpus are culturally complex and fascinating. The narration is marked by traditional components signaling both oral and written transmission. Therein lies the purpose of this study, which is to examine the characteristics that mark and define the stories from both of these traditions that have been inserted throughout the work of Persiles.

description: Mallorca, the largest island in the Balearic archipelago, is well-known throughout the world as a place of rest, holiday destination, an ideal spot to enjoy the sunshine and the sea. This postcard image is the product of tourism marketing; From its origins, cinema has contributed to this depiction through documentaries and fiction films. The Mallorca shown in the films of the 1920s and 1930s differs greatly from the one that appears in the1950s and 1960s films. During these decades, Spain and the Balearic Islands in particular underwent a true tourist boom. The unspoilt beaches, the mountains and the fields which appear in the early movies are substituted by crowded beaches, hammocks and parasols; peasant farmers and popular traditions give way to massive hotels, fashionable music bands, discos and night clubs. These images reflect the transformation that Mallorca, as many other holiday destinations in the world, underwent: a process of gradual homogenization leading to a loss of its identity.

description: The standard lore in noncommutative physics is the use of first order variational description of a dynamical system to probe the space noncommutativity and its consequences in the dynamics in phase space. As the ultimate goal is to understand the inherent space noncommutativity we propose a variational principle for noncommutative dynamical systems in configuration space, based on results of our previous work [14]. We hope that this variational formulation in configuration space can be of help to elucidate the definition of some global and dynamical properties of classical and quantum noncommutative space.

The genre of españolada (a book, film, show, etc., giving a clichéd, stereotypical image of Spain) is an interdisciplinary category established during the last four centuries through art forms belonging to the Spanish folk tradition. The objectification of this reality as a commercial product and cultural label promoted by Romanticism has served the literature, painting, music and cinema to transmit an exaggerated misconception of Spain. As an inevitable process, the españolada has also been developed in video games via a twofold dimension, which starts an on-going line of research for Game Studies in Spanish.

description: Many tasks in robot-assisted surgery require planning and controlling manipulators' motions that interact with highly deformable objects. This study proposes a realistic, time-bounded simulator based on Position-based Dynamics (PBD) simulation that mocks brain deformations due to catheter insertion for pre-operative path planning and intra-operative guidance in keyhole surgical procedures. It maximizes the probability of success by accounting for uncertainty in deformation models, noisy sensing, and unpredictable actuation. The PBD deformation parameters were initialized on a parallelepiped-shaped simulated phantom to obtain a reasonable starting guess for the brain white matter. They were calibrated by comparing the obtained displacements with deformation data for catheter insertion in a composite hydrogel phantom. Knowing the gray matter brain structures' different behaviors, the parameters were fine-tuned to obtain a generalized human brain model. The brain structures' average displacement was compared with values in the literature. The simulator's numerical model uses a novel approach with respect to the literature, and it has proved to be a close match with real brain deformations through validation using recorded deformation data of in-vivo animal trials with a mean mismatch of 4.73$\pm$2.15%. The stability, accuracy, and real-time performance make this model suitable for creating a dynamic environment for KN path planning, pre-operative path planning, and intra-operative guidance.

Temporal Journeys in Octavio Paz’ Extensive Poems

Year: 2014

description:

The study of some of the main extensive poems of Octavio Paz, from Piedra de sol (1957) to Pasado en claro (1975), allows us to underline the mnemonic mechanism often used by this author. A place, a date, a time of the day, trigger a temporal and sentimental journey. But the poetic I sometimes becomes a We. In the 1970s, the personal and intimate dimension of memory is completed by a collective dimension, both moral and political. The poem, then, expresses with great intensity a crisis of conscience. Nevertheless, it remains the best way of recovering the Eliotian “timeless moment” that Paz always sought, moment lost and regained through love, through the beloved’s presence – up to the threshold of death.

Entrance examinations in prewar Japan, late Meiji to 1941
Creators: name: Datta, Shammi
Publisher: name: University of British Columbia
Year: 2008

description: The focus of this thesis is the influence of entrance examinations on the education and lives of students in prewar Japan. I investigate the content and the extent of the tests’ effect through contemporary media reports and official criticism. I show that the influence was similar to that in postwar Japan, and that it extended beyond the few who entered the elite schools. In a direct or indirect manner, the tests affected the education of most elementary school students. Official criticism of this extensive influence was followed by vigorous reform efforts from the late 1920s. Despite these attempts, the influence persisted and was routinized. The reasons for this are explored by tracing the responses of the schools, the students and their parents to the bureaucratic reforms. These sectors of society defied official directives, for the tests (in their established form) served an important purpose for each of them. The government tried to alter the nature of the examinations and prohibited many activities resulting form them, but it had an interest in the continuation of the tests as well. This multiple interest facilitated the persistence of difficult entrance examinations and their effects. The basic reason for their extensive influence and for their multiple utility is found in the gap between the demand for and supply of post-elementary education in a society where success through academic credentials was accessible and appealing to most youths. The defiance of government orders by the concerned sectors of society illustrates aspects in the government-society relationship that suggest the need for revisions in the existing general interpretation of that relationship--the former exercising totalitarian control over the latter.

description: The collective-mode spectrum of a multicomponent magnetized ionic mixture for small wave number k is studied with the use of magnetohydrodynamics and formal kinetic theory. Apart from the usual thermal and diffusive modes, the spectrum contains a set of four oscillating modes. By evaluating the k^2 contributions to the eigenfrequencies, the damping and the dispersion of these oscillating modes are determined. The long-range nature of the Coulomb interactions is shown to imply that Burnett terms with higher-order gradients in the linear phenomenological laws have to be taken into account in order to obtain a full description of all damping and dispersion effects.

description: Tunable biphotons are highly important for a wide range of quantum applications. For some applications, especially interesting are cases where two photons of a pair are far apart in frequency. Here, we report a tunable biphoton source based on a xenon-filled hollow-core photonic crystal fiber. Tunability is achieved by adjusting the pressure of the gas inside the fiber. This allows us to tailor the dispersion landscape of the fiber, overcoming the principal limitations of solid-core fiber-based biphoton sources. We report a maximum tunability of 120 THz for a pressure range of 4 bar with a continuous shift of 30 THz/bar. At 21 bar, the photons of a pair are separated by more than one octave. Despite the large separation, both photons have large bandwidths. At 17 bar, they form a very broad (110 THz) band around the frequency of the pump.

Possibility of the total thermodynamic entropy production rate of a finite-sized isolated quantum system to be negative for the Gorini-Kossakowski-Sudarshan-Lindblad-type Markovian dynamics of its subsystem

description: We investigate a total thermodynamic entropy production rate of an isolated quantum system. In particular, we consider a quantum model of coupled harmonic oscillators in a star configuration, where a central harmonic oscillator (system) is coupled to a finite number of surrounding harmonic oscillators (bath). In this model, when the initial state of the total system is given by the tensor product of the Gibbs states of the system and the bath, every harmonic oscillator is always in a Gibbs state with a time-dependent temperature. This enables us to define time-dependent thermodynamic entropy for each harmonic oscillator and total nonequilibrium thermodynamic entropy as the summation of them. We analytically confirm that the total thermodynamic entropy satisfies the third law of thermodynamics. Our numerical solutions show that, even when the dynamics of the system is well approximated by the Gorini-Kossakowski-Sudarshan-Lindblad (GKSL)-type Markovian master equation, the total thermodynamic entropy production rate can be negative, while the total thermodynamic entropy satisfies the second law of thermodynamics. This result is a counterexample to the common belief that the total entropy production rate is non-negative when the system is under the GKSL-type Markovian dynamics.

description: In recent years, a vast increase in spectroscopic observations of transiting exoplanets has for the first time allowed us to search for broad trends in their atmospheric properties. Analysis of these observations has revealed that, even for the highly irradiated hot Jupiters, aerosol is a common presence and must be accounted for in modelling efforts. An additional challenge for hot Jupiters is the large variation in temperature across the planet, which is likely to result in partial or patchy cloud cover. As our observational capability is due to increase further with the launch of the James Webb Space Telescope, anticipated in autumn 2021, community efforts are underway to prepare modelling and analysis tools capable of recovering information about variable and patchy cloud coverage on hot exoplanets

description: We investigate the properties of a strongly interacting imbalanced mixture of bosonic $^{41}$K impurities immersed in a Fermi sea of ultracold $^6$Li atoms. This enables us to explore the Fermi polaron scenario for large impurity concentrations including the case where they form a Bose-Einstein condensate. The system is characterized by means of radio-frequency injection spectroscopy and interspecies interactions are widely tunable by means of a well-characterized Feshbach resonance. We find that the energy of the Fermi polarons formed in the thermal fraction of the impurity cloud remains rather insensitive to the impurity concentration, even as we approach equal densities for both species. The apparent insensitivity to high concentration is consistent with a theoretical prediction, based on Landau's quasiparticle theory, of a weak effective interaction between the polarons. The condensed fraction of the bosonic $^{41}$K gas is much denser than its thermal component, which leads to a break-down of the Fermi polaron description. Instead, we observe a new branch in the radio-frequency spectrum with a small energy shift, which is consistent with the presence of Bose polarons formed by $^{6}$Li fermions inside the $^{41}$K condensate. A closer investigation of the behavior of the condensate by means of Rabi oscillation measurements support this observation, indicating that we have realized Fermi and Bose polarons, two fundamentally different quasiparticles, in one cloud.

description: The decay of quantum vortex rings in counterflow regimes, visualized in Helium II with the help of solid hydrogen particles trapped to their cores, has been a puzzling issue within the usual description of superfluid vortex dynamics, grounded on the hypothesis that a vortex filament is, effectively, an extended massless object subject to a canceling superposition of Magnus and mutual friction forces. We discuss, from a general energy-budget point of view, a phenomenological solution of this problem, which relies on viscous and quantum dissipation mechanisms, the later associated to the backreaction of vortex singular structures on the surrounding two-component fluid mixture.

description: The housing market within Melbourne is becoming increasingly difficult to enter into. Tiny homes have been seen as a more affordable means of owning a home. However, land is still the primary expense when buying a property, and tiny homes do not address this. Additionally, there are legal barriers that prevent tiny homes being used as the primary residence on unused land. This research repositions the value of a tiny home away from the narrative advertised in popular media, as a cheaper home, to align more closely with observed real-world use cases. The resulting design acts as additional occupancy on a rental property within Greater Melbourne, supporting amenity for sleep, study, relaxation and storage.

description: The apparent dichotomy between information-processing and dynamical approaches to complexity science forces researchers to choose between two diverging sets of tools and explanations, creating conflict and often hindering scientific progress. Nonetheless, given the shared theoretical goals between both approaches, it is reasonable to conjecture the existence of underlying common signatures that capture interesting behaviour in both dynamical and information-processing systems. Here we argue that a pragmatic use of Integrated Information Theory (IIT), originally conceived in theoretical neuroscience, can provide a potential unifying framework to study complexity in general multivariate systems. Furthermore, by leveraging metrics put forward by the integrated information decomposition ($Φ$ID) framework, our results reveal that integrated information can effectively capture surprisingly heterogeneous signatures of complexity -- including metastability and criticality in networks of coupled oscillators as well as distributed computation and emergent stable particles in cellular automata -- without relying on idiosyncratic, ad-hoc criteria. These results show how an agnostic use of IIT can provide important steps towards bridging the gap between informational and dynamical approaches to complex systems.
Mothers’ perception of early childhood education as a function of ethnic background
Creators: name: Yung, Yanchi Gary
Publisher: name: University of British Columbia
Year: 2008

description: This exploratory study examined what mothers from different ethnic backgrounds perceived as important to their children in early childhood education programs. The question as to whether there are differences between Caucasian and non-Caucasian mothers was tested by Spearman's rank-difference correlation coefficient (rho). A total of 85 questionnaires were collected from a university-based preschool, a college-based daycare, and a community-based preschool. The mothers were asked to rank order eight developmental goals listed in the questionnaire. The development of good self-concept was ranked as the most important goal, whereas physical development was ranked the least important. There was a statistically significant correlation between the Caucasian and non-Caucasian mothers in their perception of importance of developmental goals in early childhood education (rho=.90, p<.001). To gather qualitative data, six mothers were interviewed to examine if they had a similar pattern of thinking and reasoning in regard to choosing what were and were not the important goals for their children. Despite the overall similarity in perception, mothers from different ethnic backgrounds expressed some different concerns and reasons for their decisions of what specific goals were and were not important for their children. Further studies were recommended to improve the understanding of parents' values and beliefs in regard to education in general.

description: Pion-kaon ($πK$) pairs occur frequently as final states in heavy-particle decays. A consistent treatment of $πK$ scattering and production amplitudes over a wide energy range is therefore mandatory for multiple applications: in Standard Model tests; to describe crossed channels in the quest for exotic hadronic states; and for an improved spectroscopy of excited kaon resonances. In the elastic region, the phase shifts of $πK$ scattering in a given partial wave are related to the phases of the respective $πK$ form factors by Watson's theorem. Going beyond that, we here construct a representation of the scalar $πK$ form factor that includes inelastic effects via resonance exchange, while fulfilling all constraints from $πK$ scattering and maintaining the correct analytic structure. As a first application, we consider the decay ${τ\to K_Sπν_τ}$, in particular, we study to which extent the $S$-wave $K_0^*(1430)$ and the $P$-wave $K^*(1410)$ resonances can be differentiated and provide an improved estimate of the $CP$ asymmetry produced by a tensor operator. Finally, we extract the pole parameters of the $K_0^*(1430)$ and $K_0^*(1950)$ resonances via Padé approximants, $\sqrt{s_{K_0^*(1430)}}=[1408(48)-i\, 180(48)]$ MeV and $\sqrt{s_{K_0^*(1950)}}=[1863(12)-i\,136(20)]$ MeV, as well as the pole residues. A generalization of the method also allows us to formally define a branching fraction for ${τ\to K_0^*(1430) ν_τ}$ in terms of the corresponding residue, leading to the upper limit ${\text{BR}(τ\to K_0^*(1430) ν_τ)<1.6 \times 10^{-4}}$.

For a Concept of Afro-Brazilian Literature
Creators: name: Assis Duarte, Eduardo De
Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2014

description:

The present article debates the concepts of black literature and afro-brazilian literature from the existent debates in our history and literary critics. Taking as a reference the production of afro-descendent authors from the XIX and XX centuries. Also, it tries to establish a group of elements that, once reunited, may present references of distinction that provides the specificity of the afro-brazilian literature along with the brazilian ‘tout court’ literature.

Foreignness as Extimacy
Creators: name: Seifert, Marcos
Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2014

description:

In the stories that comprise Paloma Vidal’s book Más al sur (2011) we find a variety of characters in transit who speculate about their status as foreigners. Their foreignness is not presented only as an identity’s destabilization, but also it is proposed as a way of inadequacy respect to memory and inheritance. This foreingnness allows us to think a space that combines both alienation and belonging in cultural, linguistic and family dimensions. The term extimacy is relevant to understand this position because it refers to an intimacy that has a quality of exteriority.

Why is cheating wrong?

description: Since cheating is obviously wrong, arguments against it (it provides an unfair advantage, it hinders learning) need only be mentioned in passing. But the argument of unfair advantage absurdly takes education to be essentially a race of all against all; moreover, it ignores that many cases of unfair (dis)advantages are widely accepted. That cheating can hamper learning does not mean that punishing cheating will necessarily favor learning, so that this argument does not obviously justify sanctioning cheaters. -- Keywords: academic dishonesty, academic integrity, academic misconduct, education, ethics, homework, plagiarism

description: This report presents an independent evaluation of the extent to which Together for Humanity’s programs – particularly the Prejudice and Belonging and Good Practice Programs – achieve their aims. Critical, was understanding the extent to which Together for Humanity programs support learners to improve their understandings and skills in intercultural understanding, belonging and connectedness, resilience, compassion, and creative and critical thinking. Further, the report contextualises Together for Humanity’s operations within an updated scope of current research on best practice. A qualitative methodology was utilised. Students and school staff participated in in-depth interviews pre- and post-program delivery. Participants were from eight diverse primary and secondary schools across the South-Eastern Sydney metropolitan region where Together for Humanity programs were delivered from 2018 to 2019. The evaluation found that TFH programs are effective in assisting students to challenge stereotypes and alleviate their fears; TFH programs empower students to deal with prejudice and discrimination and promote the acquisition of empathy and mutual acceptance and belonging. TFH’s operational processes are also discussed, including staff engagement, student involvement, and suggestions for enhanced operations. The authors draw five key recommendations from the findings: to engage a whole-school community approach, to enhance student ownership of programs, increase inclusivity of programs along particular domains, consider the development of a social media strategy and to review specific program mechanisms.We recognise that recommendations can only be implemented to the extent that available funding can support them. Given currently rising levels of discrimination, for example, Islamophobia and anti-Semitism in Australia and more broadly; there is an urgent need for antiracism education and promotion of intercultural understanding in schools making the work of TFH compellingly relevant.
Formation of an extended stellar halo around an ultra-faint dwarf galaxy following one of the earliest mergers from galactic building blocks

description: Ultra-faint dwarf galaxies (UFDs) are promising observable proxies to building blocks of galaxies formed in the early Universe. We study the formation and evolution of UFDs using cosmological hydrodynamic simulations. In particular, we show that a major merger of two building block galaxies with 3,900 Msun and 7,500 Msun at the cosmic age of 510 Myr results in a system with an extended stellar distribution consistent with the de Vaucouleurs profile. The simulated galaxy has an average stellar metallicity of [Fe/H]=-2.7 and features a metallicity gradient. These results closely resemble the properties of a recently discovered UFD, Tucana II, which is extremely metal-poor and has a spatially extended stellar halo with the more distant stars being more metal-poor. Our simulation suggests that the extended stellar halo of Tucana II may have been formed through a past major merger. Future observational searches for spatially extended structures around other UFDs, combined with further theoretical studies, will provide tangible measures of the evolutionary history of the ancient, surviving satellite galaxies.

Dealing with Metonymic Readings of Named Entities
Creators: name: Poibeau, Thierry
Publisher: name: arXiv
Year: 2006
Subjects: subject: Artificial Intelligence (cs.AI)
subject: Computation and Language (cs.CL)
subject: FOS: Computer and information sciences

description: The aim of this paper is to propose a method for tagging named entities (NE), using natural language processing techniques. Beyond their literal meaning, named entities are frequently subject to metonymy. We show the limits of current NE type hierarchies and detail a new proposal aiming at dynamically capturing the semantics of entities in context. This model can analyze complex linguistic phenomena like metonymy, which are known to be difficult for natural language processing but crucial for most applications. We present an implementation and some test using the French ESTER corpus and give significant results.

Violation of Strong Energy Condition in Effective Loop Quantum Cosmology

description: In loop quantum cosmology nonperturbative modification to a scalar matter field at short scales implies inflation which also means a violation of the strong energy condition. In the framework of effective Hamiltonian we discuss the issue of violation of the strong energy condition in the presence of quantum geometry potential. It shows that the appearance of quantum geometry potential strengthens the violation of the strong energy condition in small volume regions. In the small volume regions superinflation can easily happen. Furthermore, when the evolution of the universe approaches the bounce scale, this trend of violating the strong energy condition can be greatly amplified.

description: Antibiotic-resistant bacteria are becoming increasingly difficult to treat. In the United States, at least 2 million people are diagnosed with an antibiotic-resistant infection yearly (CDC 2013). Bacteriophage therapy serves as an emerging solution for the treatment of bacterial infections, and understanding environmental conditions that affect bacteriophage stability is fundamental to developing effective phage treatments. Additionally, bacteriophages exhibit a varying degree of host range specificity that determines their utility for targeting specific bacterial hosts and their efficacy in applications of phage therapies. This study tested the thermal stability of a novel Bacillus subtilis bacteriophage, Zorp, by measuring bacterial lysis after preheating phage at different temperatures. Experiments demonstrated that phage Zorp was stable between 35ºC and 65ºC, but became inactivated when heated to 80ºC. The phage Zorp genome was unable to be sequenced; consequently, the genome of Gordonia terrae phage Tanis was annotated using a suite of bioinformatics programs. Comparative genomic analyses supported established clustering patterns and evolutionary relationships among phage, suggesting that actinobacteriophages share genomic similarity while Bacillus phages were more genetically unique. Notably, phages which share nucleotide similarity also share similar codon biases, all of which may be reliably organized depending on the genus of the host they are infecting, suggesting a model for predicting host specificity given raw sequence data. In summary, our results indicate that Phage Zorp is thermally stable and thus a viable candidate for phage therapy. Analysis of Gordonia phage Tanis indicates variance in the suitability of phage clusters for targeted phage therapy of pathogenic bacteria.
