The University, the Universe, the World, and "Globalization"
Creators: name: Miyoshi, Masao
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2005

description: The discipline of the humanities - like the idea of "culture "- is a byproduct of the formation of the nation-state in the nineteenth-century West. Its decline began with the fundamental skepticism toward the idea of totality, authority, and centrality, which was replaced fairly rapidly by the ideology of difference, especially as the old colonies began to gain "independence." What has gradually emerged from this initially liberating movement, how­ever, is social and intellectual fragmentation. Socially, it coincided with the neo-liberal development. Intellectually and institutionally, it has en­couraged and has been encouraged by the emphasis on specialization and theorization." Yet, the way todays scholars and writers of different "kinds (in gender, ethnicity, class, and discipline) have ceased to talk together, discuss together, or even disagree together is quite alarm­ing - especially now that the environmental deterioration demands that the planet be understood and experienced as a commonality that belongs to every single being on earth. The humanities can now seize this demoral­ized moment and reorganize itself around the planet and the universe, the ultimate totality as the central imaginary. Environmental sustenance cannot be considered without rethinking social totality. The ever widening gap between the rich and the poor both among and within nations is a part of the ecological deterioration. This time, in other words, the need for a radical reformation is not merely ethical or political, but a necessity for everyone. Far from being vulnerable to the assault by totalitarianism, this transformation is integrated with singularities and connectives. Unlike the nation-state, the planet (and the universe) is an inspiring commonality on which writers, scholars, and scientists can work together in a truly transdisciplinary endeavor.

description: This is the first study in which the impact of a new bio-packaging on histamine formation in mackerel was investigated. To monitor the preservation of fresh fish samples a treatment with innovative polymeric film and a soaking procedure in liquid new biomaterial was adopted. Ultra HPLC diode array detection (UHPLC-DAD) analyses for histamine monitoring were performed on fresh, packaged, and soaked mackerel samples at different time. The histamine content threshold value was up to 7 days, and after this period the results showed that histamine levels were affected by application of biomaterial. Significant increase was detected in sample that was not treated with biofilm. The new biofilm extended the shelf-life and reveals a promising packaging system to prevent histamine biosynthesis.

description: The role of time in quantum mechanics is discussed. The differences between ordinary observables and an observable which corresponds to the time of an event is examined. In particular, the time-of-arrival of a particle to a fixed location is not an ordinary quantum mechanical observable. While we can measure if the particle arrives, we argue that the time at which it arrives always has an inherent ambiguity. The minimum inaccuracy of time-of-arrival measurements is given by dt>1/E where E is the kinetic energy of the particle. The use of time-of-arrival operators, as well as current operators, is examined critically.

description: We report on BeppoSAX and Chandra observations of three Hard X-Ray Transients in quiescence containing fast spinning (P<5 s) neutron stars: A 0538-66, 4U 0115+63 and V 0332+53. These observations allowed us to study these transients at the faintest flux levels thus far. Spectra are remarkably different from the ones obtained at luminosities a factor >10 higher, testifying that the quiescent emission mechanism is different. Pulsations were not detected in any of the sources, indicating that accretion of matter down to the neutron star surface has ceased. We conclude that the quiescent emission of the three X-ray transients likely originates from accretion onto the magnetospheric boundary in the propeller regime and/or from deep crustal heating resulting from pycnonuclear reactions during the outbursts.

description: Mutations allowing pathogens to escape host immunity promote the spread of infectious diseases in heterogeneous host populations and can lead to major epidemics. Understanding the conditions that slow down this evolution is key for the development of durable control strategies against pathogens. Here we use theory and experiments to compare the efficacy of three strategies for the deployment of resistance: (i) a mixing strategy where the host population contains two single-resistant genotypes, (ii) a pyramiding strategy where the host carries a double-resistant genotype, (iii) a combining strategy where host population is a mix of a single-resistant genotype and a double-resistant genotype. First, we use evolutionary epidemiology theory to clarify the interplay between demographic stochasticity and evolutionary dynamics to show that the pyramiding strategy always yields lower probability of evolutionary emergence. Second, we test experimentally these predictions with the introduction of bacteriophages into bacterial populations where we manipulated the diversity and the depth of immunity using a CRISPR-Cas system. These biological assays confirm that pyramiding multiple defenses into the same host genotype and avoiding combination with single-defense genotypes is a robust way to reduce pathogen evolutionary emergence. The experimental validation of these theoretical recommendations has practical implications for the optimal deployment of resistance varieties in agriculture and for the design of durable vaccination strategies.

Hauntologies of Form: Race, Genre, and the Literary World System
Creators: name: Cooppan, Vilashini
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2005

description: With its roots in world systems theory on the one hand, and the contem­porary realities of globalization on the other, the project of world litera­ture has taken capital as a crucial unit of analysis. This essay argues that genre and race be given a similar centrality in the theory of world literature. Like capital, genre and race are shown to be spectral," in Jacques Derridas sense of entities that resist straightforward narratives of progression and presence. Building on genre theorists such as Claudio Guillen, Michael McKeon, and Fredric Jameson, the essay discusses genres oscillating, forward-and-backward time. It then compares that model of generic time to the idea of race, as discussed by world systems theorists and discourse theorists. In the latter, the essay finds the basis for races speciality. Reading the spectral logics of capital, genre, and race together, and with specific reference to the novel, the essay argues for a hauntology of world literary history.

description: Two very different problems that can be studied by renormalization group methods are discussed with the aim of showing the conceptual unity that renormalization group has introduced in some areas of theoretical Physics. The two problems are: the ground state theory of a one dimensional quantum Fermi liquid and the existence of quasi periodic motions in classical mechanical systems close to integrable ones. I summarize here the main ideas and show that the two treatments, although completely independent of each other, are strikingly similar.

Jack London on the Fringe of Things
Creators: name: Auerbach, Jonathan
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2005

description: Looking at a pair of Jack London stories set in the South Seas (from Polynesia to Melanesia), this essay traces the material fate of objects that take on special significance during disorienting transactions between Westerners and native islanders encountering one another across nebulous zones of contact on land and at sea. For Westerners these commodities (including slaves) circulate in an abstract global system of exchange, homogenized in value either by money or trade items such as tobacco. But for the Pacific natives these objects come to signify a kind of irreducible subjectivity ultimately tied to a corporeal integrity that struggles to resist the depersonalizing tendencies of worldwide capitalism. While London understands that the postcolonial condition makes it impos­sible to return to indigenous forms of value and identity, his ironic depic­tions of these entanglements between peoples and things (suggesting at once the power and limits of Western incursion) testify to his rather shrewd understanding of early twentieth-century globalization and its discontents.

Interplaying National and Transnational Perspectives in post-1989 Comparative Literary History
Creators: name: Cornis-Pope, Marcel
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2005

description: The break-up of the bipolar world system in 1989 has removed the traditional ideological polarizations between East and West, "first" and "second" world, but has to some extent replaced them with nationalistic and ethnocentric perspectives that promote new cultural divisions. Under these circumstances, the input of a mediating consciousness is needed now more than ever. By comparing, translating and interfacing cultures, this type of consciousness can help us rediscover that middle ground between Eastern and Western, dominant and peripheral that we have neglected because of our polarized worldviews. Post-1989 comparative literary history can help us reconstruct that middle ground of intercultural coexistence, emphasizing "transference," "translation," and "cultural con­tact." The multifaceted landscape of East Central Europe, punctuated by multicultural and minority discourses, is an especially fertile ground for a transnational literary history that, while not neglecting the points of conflict, will foreground the conjunctions and crossings between cultures. I test these claims on examples taken from the History of the Literary Cultures of East-Central Europe, a multi-volume work I am currently co-editing with John Neubauer.

Enhanced magnetic fluctuations in doped spin-Peierls systems: a single-chain model analysis

description: We analyze by means of real space Renormalization Group (RG) as well as by exact diagonalizations the properties of a single-chain model of a doped spin-Peierls system, where a major role is played by the localized moments created by the impurities. We are able to follow analytically the RG flow, which allows us to determine the relevant cross-over temperatures. In particular, we find an enhancement of magnetic correlations due to disorder, coexisting with an underlying dimerization, in an intermediate temperature range below the spin-Peierls critical temperature and above the coherence temperature of a regular array built by those localized moments (so-called soliton bandwidth). The possible relevance of these results to the doped inorganic spin-Peierls compound CuGeO$_3$ is discussed.

description: Since there is no known symmetry in Nature that prevents a non-minimal coupling between the dark energy (DE) and cold dark matter (CDM) components, such a possibility constitutes an alternative to standard cosmology, with its theoretical and observational consequences being of great interest. In this paper we propose a new null test on the standard evolution of the dark sector based on the time dependence of the ratio between the CDM and DE energy densities which, in the standard $Λ$CDM scenario, scales necessarily as $a^{-3}$. We use the latest measurements of type Ia supernovae, cosmic chronometers and angular baryonic acoustic oscillations to reconstruct the expansion history using model-independent Machine Learning techniques, namely, the Linear Model formalism and Gaussian Processes. We find that while the standard evolution is consistent with the data at $3σ$ level, some deviations from the $Λ$CDM model are found at low redshifts, which may be associated with the current tension between local and global determinations of $H_0$.

description: Croton antisyphiliticus Mart. is a plant popularly used in folk medicine by traditional communities from Brazilian savannah to treat general inflammation. According to ethnopharmacological data, this specie can be considered a source of biologically active molecules for the development of new drugs. Thereby, this study reports the results of the dereplication approach of C. antisyphiliticus roots extracts and the in vivo evaluation of its potential antinociceptive and anti-inflammatory in albino Swiss mice. Based on HPLC coupled to Q-Exactive Orbitrap Mass Spectrometer and using GNPS, a total of thirteen polyphenolic compounds were noticed, including four compounds that have been reported for the first time in the genus Croton. Ethanolic and aqueous roots extracts demonstrated a dose-dependent inhibition for the number of writes, reduced pain induced by formalin and hyperalgesia induced by carrageenan. These extracts also reduced paw edema, cell migration, and myeloperoxidase activity, with effects similar to indomethacin and dexamethasone drugs.

description: We discuss topological properties of the ground state of spatially homogeneous ensemble of fermions. There are several classes of topologically different fermionic vacua; in each case the momentum space topology of the vacuum determines the low-energy (infrared) properties of the fermionic energy spectrum. Among them there is a class of the gapless systems which is characterized by the Fermi-hypersurface, which is the topologically stable singularity in momentum space. This class contains the conventional Landau Fermi-liquid and also the non-Landau Luttinger Fermi-liquid. Another important class of gapless systems is characterized by the topologically stable point nodes (Fermi points). Superfluid 3He-A and electroweak vacuum belong to this universality class. The fermionic quasiparticles (particles) in this class are chiral: close to the Fermi points they are left-handed or right-handed massless relativistic particles. Since the spectrum becomes relativistic at low energy, the symmetry of the system is enhanced in the low-energy edge. The low-energy dynamics acquires local invariance, Lorentz invariance and general covariance, which become better and better when the energy decreases. Interaction of the fermions near the Fermi point leads to collective bosonic modes, which look like effective gauge and gravitational fields. Since the vacuum of superfluid 3He-A and electroweak vacuum are topologically similar, we can use 3He-A for simulation of many phenomena in high energy physics, including axial anomaly. 3He-A textures induce a nontrivial effective metrics of the space, where the free quasiparticles move along geodesics. Possible simulation in 3He-A of event horizon, Hawking radiation, rotating vacuum and conical space are discussed.

Other People's Heroes: Intertexts, History, and Comparative Resistance to Totalization
Creators: name: Lee, Gregory B.
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2005

description: Given the remit of addressing the potential of "worlded" comparative literature, I raise here two principal questions. First, the importance of history in reading intertexts, or the historicity of the reception of texts (a reception which is often shielded by a penumbra of ignorance from those for whom the text was intended" or from those who are the object of interest of a particular text), for in the shade of parallel but distinct trajectories of history yet further meaning is produced. Texts discussed include the poetry of Byron in the context of its reception in China, the Chinese ballad Mulan, and its detournement by Disney. The second re­flection is on the nature of the impact of the global" on literary and cultural studies, and on the meaning of global or world cultural production; a consideration of this seemingly new "worldly" culture also obliging us to invoke the historicity of this concept. In discussing these two areas, I tangentially seek to broach my discomfort with the metaphors with which we imagine and write literary and cultural studies.

Weakly Supervised Disentangled Representation for Goal-conditioned Reinforcement Learning

description: Goal-conditioned reinforcement learning is a crucial yet challenging algorithm which enables agents to achieve multiple user-specified goals when learning a set of skills in a dynamic environment. However, it typically requires millions of the environmental interactions explored by agents, which is sample-inefficient. In the paper, we propose a skill learning framework DR-GRL that aims to improve the sample efficiency and policy generalization by combining the Disentangled Representation learning and Goal-conditioned visual Reinforcement Learning. In a weakly supervised manner, we propose a Spatial Transform AutoEncoder (STAE) to learn an interpretable and controllable representation in which different parts correspond to different object attributes (shape, color, position). Due to the high controllability of the representations, STAE can simply recombine and recode the representations to generate unseen goals for agents to practice themselves. The manifold structure of the learned representation maintains consistency with the physical position, which is beneficial for reward calculation. We empirically demonstrate that DR-GRL significantly outperforms the previous methods in sample efficiency and policy generalization. In addition, DR-GRL is also easy to expand to the real robot.

Optimized Fourier Bilateral Filtering

Subjects: subject: Image and Video Processing (eess.IV)

description: We consider the problem of approximating a truncated Gaussian kernel using Fourier (trigonometric) functions. The computation-intensive bilateral filter can be expressed using fast convolutions by applying such an approximation to its range kernel, where the truncation in question is the dynamic range of the input image. The error from such an approximation depends on the period, the number of sinusoids, and the coefficient of each sinusoid. For a fixed period, we recently proposed a model for optimizing the coefficients using least-squares fitting. Following the Compressive Bilateral Filter (CBF), we demonstrate that the approximation can be improved by taking the period into account during the optimization. The accuracy of the resulting filtering is found to be at least as good as CBF, but significantly better for certain cases. The proposed approximation can also be used for non-Gaussian kernels, and it comes with guarantees on the filtering accuracy.

description: We study the variances of the coordinates of an event considered as quantum observables in a Poincare' covariant theory. The starting point is their description in terms of a covariant positive-operator-valued measure on the Minkowski space-time. Besides the usual uncertainty relations, we find stronger inequalities involving the mass and the centre-of-mass angular momentum of the object that defines the event. We suggest that these inequalities may help to clarify some of the arguments which have been given in favour of a gravitational quantum limit to the accuracy of time and space measurements.

Mapping Texts Differently: A Case for Re-Reading the South African Imaginary
Creators: name: Gunner, Liz
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2005

description: This essay argues that an overly narrow conception of what constitutes a national or regional literature can skew the way in which literary history is "read" and a national and regional identity is understood. In the African and the South African case, the ongoing production and consumption of performed art in the form of song constitutes a major part of the way in which people imagine themselves in the world, both locally and globally. Such songs often stem from older oral forms and are frequently available through the electronic media. In other cases, classic art forms such as praise poetry are still present as ways of mediating identity and making history. The essay takes particular examples of genres that either cross between print and performance, or, when seen together as a co- presence, provide a much firmer understanding of how the "self-writing" of South Africa is taking place. The essay takes the example of praise poetry, and discusses how the tragic phenomenon of the pandemic of AIDS surfaces first in the contemporary performance tradition of isicathamiya, or nightsong,' and secondly in the novel Welcome to our Hillbrow by Phaswane Mpe. I argue that if the South African imaginary is to be deeply understood, such cross-readings need to take place. Only when literary scholars find a means of accessing such readings, can we begin to speak of meaningful transcultural literary histories.

Limonene (0.64 to 44.43%) and linalool (0.36 to 2.12%) were identified in all EOs by gas chromatography coupled to mass spectrometry analysis. The major components (relative intensity ≥ 10%) were cis-dihydro carvone, carvone, and cis-piperitone epoxide for Minthostachys mollis leaves; β-pinene, limonene, and ledol for Lepechinia heteromorpha leaves; limonene, neral, and geranial for Aloysia citriodora, both leaves and flowers; α-pinene, and limonene for Myrcianthes myrsinoides leaves; and α-pinene, β-myrcene, and (E)-β-Ocimene for Dalea carthagenensis leaves. Constituted by (Z)-β-ocimene, dihydrotagetone, (Z)-tagetone, and car-3-en-2-one, EO of Tagetes minuta leaves induced an irreversible cytostatic effect against MCF-7 human breast tumor cells. Further in vivo studies must be carried out to establish the safe and efficient dose of T. minuta EO as adjuvant treatment in oncological therapies.

If grains are randomly added to the pile, the power spectrum exhibits $1/f^2$ behaviour. The profile fluctuations of the pile under different driving mechanisms are also discussed.

description: We study the linear metric perturbations of the Reissner-Nordström solution for the case of axial perturbation modes. We find that the well-known perturbative analysis fails for the case of dipole $(l=1)$ perturbations, although valid for higher multipoles. We define new radial functions, with which the perturbation formalism is generalized to all multipole orders, including the dipole. We then complete the solution by constructing the perturbed metric and Maxwell tensors.

description: We show that weak off-diagonal disorder in degenerate ground state conjugated polymers results in a finite density of randomly positioned kinks (solitons and antisolitons) in the lattice dimerization. For realistic values of the disorder, these kinks should clearly show up in the optical and magnetic properties.

SU(2)$_{\rm CMB}$ and the cosmological model: angular power spectra

description: Driven by the CMB temperature-redshift ($T$-$z$) relation as demanded by deconfining SU(2) Yang-Mills thermodynamics, an according cosmological model is proposed and analysed. This model -- SU(2)$_\CMB$ -- exhibits a dark sector, representing $Λ$CDM with a certain late-time dark-matter density which transitions to a reduced (present-day) density parameter at high $z$. We statistically analyse constraints on cosmological parameters directly imposed by the values of the standard co-moving ruler $r_d$ and the angular size of the sound horizon $θ_*$. Compared to the $Λ$CDM best fit to 2015 Planck data, we require an increased (present-day) dark matter density when $r_d\cdot H_0=$\,const and a value $H_0\sim 73.5$ km\,s$^{-1}$Mpc$^{-1}$ -- typical for local extractions -- are used. The ratio between the density parameters of primordial and late-time dark matter ranges between 0.5 and 0.7. We confirm this trend by fitting the predictions of SU(2)$_\CMB$, obtained from a modified CLASS code, to the angular power spectra TT, TE, and EE. We consider adiabatic, scalar primordial curvature perturbations and distinguish two treatments of thermal quasi-particles in the perturbation equations. Best fits predict a red-tilted primordial power spectrum. Moreover, a low baryon density is obtained compared with the coincidence value of BBN, the $Λ$CDM best fit of the 2015 Planck data, and the observed deuterium abundance. Our derived values of $H_0$ support the results of local cosmological observations. Also, there is a tendency for late reionisation.

description: The rapid spread of SARS-CoV-2 and its infection severity require an urgent development of antiviral agents. In this respect, Usnic acid (UA), a natural dibenzofuran derivative, exerts antiviral activity against several viruses, though presenting very low solubility and high cytotoxicity. Here, UA was complexed with β-cyclodextrins (β-CDs), a pharmaceutical excipient used to improve drug solubility. The cytotoxic activity, tested on Vero E6 cells, revealed no effect for β-CDs alone whereas significant cytotoxicity for the UA/β-CDs complex was recorded at concentrations ≥ 0.05%. The neutralizing activity towards the fusion of SARS-CoV-2 Spike Pseudovirus showed no effects for β-CDs alone whereas the UA/β-CDs complex, when pre-incubated with the viral particles, efficiently inhibited the Pseudoviral fusion of about 90 and 82% at non-cytotoxic concentrations of 0.03 and 0.01%, respectively. In conclusion, although further evidences are needed to clarify the exact inhibition mechanism, UA/β-CDs complex could be useful in SARS-CoV-2 infection.

description: Can Multimodal Large Language Models (MLLMs), with capabilities in perception, recognition, understanding, and reasoning, function as independent assistants in art evaluation dialogues? Current MLLM evaluation methods, which rely on subjective human scoring or costly interviews, lack comprehensive coverage of various scenarios. This paper proposes a process-oriented Human-Computer Interaction (HCI) space design to facilitate more accurate MLLM assessment and development. This approach aids teachers in efficient art evaluation while also recording interactions for MLLM capability assessment. We introduce ArtMentor, a comprehensive space that integrates a dataset and three systems to optimize MLLM evaluation. The dataset consists of 380 sessions conducted by five art teachers across nine critical dimensions. The modular system includes agents for entity recognition, review generation, and suggestion generation, enabling iterative upgrades. Machine learning and natural language processing techniques ensure the reliability of evaluations. The results confirm GPT-4o's effectiveness in assisting teachers in art evaluation dialogues.

description: We investigate the low-temperature magnetic properties of the molecule-based chiral spin chain [Cu(pym)(H$_2$O)$_4$]SiF$_6\cdot$H$_2$O (pym = pyrimidine). Electron-spin resonance, magnetometry and heat capacity measurements reveal the presence of staggered $g$ tensors, a rich low-temperature excitation spectrum, a staggered susceptibility and a spin gap that opens on the application of a magnetic field. These phenomena are reminiscent of those previously observed in non-chiral staggered chains, which are explicable within the sine-Gordon quantum-field theory. In the present case, however, although the sine-Gordon model accounts well for the form of the temperature-dependence of the heat capacity, the size of the gap and its measured linear field dependence do not fit with the sine-Gordon theory as it stands. We propose that the differences arise due to additional terms in the Hamiltonian resulting from the chiral structure of [Cu(pym)(H$_2$O)$_4$]SiF$_6\cdot$H$_2$O, particularly a uniform Dzyaloshinskii-Moriya coupling and a four-fold periodic staggered field.
