description: We develop an effective spin theory to describe magnetic properties of the $ν=2$ Quantum Hall bilayer systems. In the absence of disorder this theory gives quantitative agreement with the results of microscopic Hartree-Fock calculations, and for finite disorder it predicts the existence of a novel spin Bose glass phase. The Bose glass is characterized by the presence of domains of canted antiferromagnetic phase with zero average antiferromagnetic order and short range mean antiferromagnetic correlations. It has infinite antiferromagnetic transverse susceptibility, finite longitudinal spin susceptibility and specific heat linear in temperature. Transition from the canted antiferromagnet phase to the spin Bose glass phase is characterized by a universal value of the longitudinal spin conductance.

description: Moderate resolution spectra have been recorded for a sample of radio-selected QSOs (z=2.5) discovered in the ``Faint Images of the Radio Sky at Twenty centimeters'' (FIRST) VLA survey. This work is motivated by the study of a heterogeneous set of QSO absorption line spectra that showed that as many as 36% of the absorbers normally thought to be intergalactic are correlated with physical properties of the background QSO, including the radio source spectral index. Spectra were taken for 24 newly discovered quasars in order to test this finding on a more homogeneous data set. The spectra have been searched for the most frequently observed absorption lines. The absorption line properties are compared to the radio properties of the quasars. The primary results are summarized as follows: 1) an excess of CIV absorbers in flat-spectrum quasars as compared to steep-spectrum quasars is confirmed (based on a total sample of 165 systems), 2) a small excess of high-velocity CIV absorbers is seen in radio-quiet QSOs as compared to radio-loud quasars, and 3) the Sloan Digital Sky Survey QSO spectra will allow for the detection of a high-velocity, narrow, intrinsic population of absorbers that is as small as 7% of the CIV absorber population in QSOs at z=2.5.

description: A recurring theme in topological matter is the protection of unusual electronic states by symmetry, for example, protection of the surface states in Z2 topological insulators by time reversal symmetry [1-3]. Recently interest has turned to unusual surface states in the large class of nonsymmorphic materials [4-11]. In particular KHgSb is predicted to exhibit double quantum spin Hall (QSH) states [10]. Here we report observation of a novel feature of the Hall conductivity in KHgSb in strong magnetic field B. In the quantum limit, the Hall conductivity is observed to fall exponentially to zero, but the diagonal conductivity is finite. A large gap protects this unusual zero-Hall state. We propose that, in this limit, the chemical potential drops into the bulk gap, intersecting equal numbers of right and left-moving QSH surface modes to produce the zero-Hall state.

description: We present an analysis of the magnetic response of a mesoscopic superconductor, i.e. a system of sizes comparable to the coherence length and to the London penetration depth. Our approach is based on special properties of the two dimensional Ginzburg-Landau equations, satisfied at the dual point $(κ= \frac{1}{\sqrt{2}}).$ Closed expressions for the free energy and the magnetization of the superconductor are derived. A perturbative analysis in the vicinity of the dual point allows us to take into account vortex interactions, using a new scaling result for the free energy. In order to characterize the vortex/current interactions, we study vortex configurations that are out of thermodynamical equilibrium. Our predictions agree with the results of recent experiments performed on mesoscopic aluminium disks.

description: Classical phenomenological aspects of acoustic perturbations on a draining bathtub geometry where a surface with reflectivity $\mathcal{R}$ is set at a small distance from the would-be acoustic horizon, which is excised, are addressed. Like most exotic compact objects featuring an ergoregion but not a horizon, this model is prone to instabilities when $|\mathcal{R}|^2\approx 1$. However, stability can be attained for sufficiently slow drains when $|\mathcal{R}|^2\lesssim70\%$. It is shown that the superradiant scattering of acoustic waves is more effective when their frequency approaches one of the system's quasi-normal mode frequencies.

The boundary $K$ matrices depending on the local moments of the impurities are presented as a nontrivial realization of the graded reflection equation algebras in a two-dimensional impurity Hilbert space. Further,the model is solved by using the algebraic Bethe ansatz method and the Bethe ansatz equations are obtained.

description: Cardiac stem cell therapy has been considered as apromising strategy for heart tissue regeneration. Yet achieving cardiacdifferentiation after stem cell transplantation remains challenging. Thiscompromises the efficacy of current stem cell therapy. Delivery of cellsusing matrices that stimulate the cardiac differentiation may improve thedegree of cardiac differentiation in the heart tissue. In this report, weinvestigated whether elastic modulus of highly flexible poly(N-isopropylamide)(PNIPAAm)-based hydrogels can be modulated to stimulate theencapsulated cardiosphere derived cells (CDCs) to differentiate intocardiac lineage under static condition and dynamic stretching that mimicsthe heart beating condition. We have developed hydrogels whose modulido not change under both dynamic stretching and static conditions for 14days. The hydrogels had the same chemical structure but different elasticmoduli (11, 21, and 40 kPa). CDCs were encapsulated into thesehydrogels and cultured under either native heart-mimicking dynamic stretching environment (12% strain and 1 Hz frequency) orstatic culture condition. CDCs were able to grow in all three hydrogels. The greatest growth was found in the hydrogel withelastic modulus of 40 kPa. The dynamic stretching condition stimulated CDC growth. The CDCs demonstrated elastic modulusdependentcardiac differentiation under both static and dynamic stretching conditions as evidenced by gene and proteinexpressions of cardiac markers such as MYH6, CACNA1c, cTnI, and Connexin 43. The highest differentiation was found in the40 kPa hydrogel. These results suggest that delivery of CDCs with the 40 kPa hydrogel may enhance cardiac differentiation in theinfarct hearts.

description: We present high resolution radio data at 3.5 and 20 cm from the VLA in the A configuration for 144 quasars with known CIV absorption line properties. Using these measurements, we compare and contrast a number of quasar orientation indicators. These quantities are used to study the velocity distribution of CIV absorption lines as a function of quasar orientation measures. That there is an excess of narrow, high-velocity CIV absorbers in flat-spectrum quasars as compared to steep-spectrum quasars is confirmed. Orientation indicators that are not based upon spectral indices (e.g. R_V and the core-to-lobe ratio) do not show the same effect. These seemingly contradictory results may be reconciled if the absorber distribution is not strictly a function of orientation, but rather a function of intrinsic radio properties that may or may not be good orientation indicators.

description: Stem-cell therapy has the potential to regeneratedamaged heart tissue after a heart attack. Injectable hydrogels may beused as stem-cell carriers to improve cell retention in the heart tissue.However, current hydrogels are not ideal to serve as cell carriers becausemost of them block blood vessels after solidification. In addition, thesehydrogels have a relatively slow gelation rate (typically >60 s), whichdoes not allow them to quickly solidify upon injection, so as toefficiently hold cells in the heart tissue. As a result, the hydrogels andcells are squeezed out of the tissue, leading to low cell retention. Toaddress these issues, we have developed hydrogels that can quicklysolidify at the pH of an infarcted heart (6−7) at 37 °C but cannotsolidify at the pH of blood (7.4) at 37 °C. These hydrogels are alsoclinically attractive because they can be injected through catheterscommonly used for minimally invasive surgeries. The hydrogels weresynthesized by free-radical polymerization of N-isopropylacrylamide, propylacrylic acid, hydroxyethyl methacrylate-cooligo(trimethylene carbonate), and methacrylate poly(ethylene oxide) methoxy ester. Hydrogel solutions were injectablethrough 0.2-mm-diameter catheters at pH 8.0 at 37 °C, and they can quickly form solid gels under pH 6.5 at 37 °C. All of thehydrogels showed pH-dependent degradation and mechanical properties with less mass loss and greater complex shear modulusat pH 6.5 than at pH 7.4. When cardiosphere-derived cells (CDCs) were encapsulated in the hydrogels, the cells were able tosurvive during a 7-day culture period. The surviving cells were differentiated into cardiac cells, as evidenced by the expression ofcardiac markers at both the gene and protein levels, such as cardiac troponin T, myosin heavy chain α, calcium channelCACNA1c, cardiac troponin I, and connexin 43. The gel integrity was found to largely affect CDC cardiac differentiation. Theseresults suggest that the developed dual-sensitive hydrogels may be promising carriers for cardiac cell therapy.

description: We present results on the low-frequency dynamical and transport properties of random quantum systems whose low temperature ($T$), low-energy behavior is controlled by strong disorder fixed points. We obtain the momentum and frequency dependent dynamic structure factor in the Random Singlet (RS) phases of both spin-1/2 and spin-1 random antiferromagnetic chains, as well as in the Random Dimer (RD) and Ising Antiferromagnetic (IAF) phases of spin-1/2 random antiferromagnetic chains. We show that the RS phases are unusual `spin metals' with divergent low-frequency spin conductivity at T=0, and we also follow the conductivity through novel `metal-insulator' transitions tuned by the strength of dimerization or Ising anisotropy in the spin-1/2 case, and by the strength of disorder in the spin-1 case. We work out the average spin and energy autocorrelations in the one-dimensional random transverse field Ising model in the vicinity of its quantum critical point. All of the above calculations are valid in the frequency dominated regime $ω\agt T$, and rely on previously available renormalization group schemes that describe these systems in terms of the properties of certain strong-disorder fixed point theories. In addition, we obtain some information about the behavior of the dynamic structure factor and dynamical conductivity in the opposite `hydrodynamic' regime $ω< T$ for the special case of spin-1/2 chains close to the planar limit (the quantum x-y model) by analyzing the corresponding quantities in an equivalent model of spinless fermions with weak repulsive interactions and particle-hole symmetric disorder.

description: Integrable Kondo impurities in the one-dimensional supersymmetric U model of strongly correlated electrons are studied by means of the boundary graded quantum inverse scattering method. The boundary K matrices depending on the local magnetic moments of the impurities are presented as nontrivial realizations of the reflection equation algebras in an impurity Hilbert space. Furthermore, the model Hamiltonian is diagonalized and the Bethe ansatz equations are derived. It is interesting to note that our model exhibits a free parameter in the bulk Hamiltonian but no free parameter exists on the boundaries. This is in sharp contrast to the impurity models arising from the supersymmetric t-J and extended Hubbard models where there is no free parameter in the bulk but there is a free parameter on each boundary.

The quantum Zeno and anti-Zeno effects: from weak to strong system-environment coupling

description: By repeatedly measuring a quantum system, the evolution of the system can be slowed down (the quantum Zeno effect) or sped up (quantum anti-Zeno effect). We study these effects for a single two-level system coupled to a collection of harmonic oscillators. Previously, such systems have been studied in both the weak and the strong system-environment coupling regimes. In this paper, we apply a polaron transformation in a manner that allows us to study the quantum Zeno and anti-Zeno effects for a large variety of system-environment parameters. Using this approach, we reproduce previous results for the weak and strong system-environment coupling regimes. Moreover, as long as the environment is super-Ohmic, we show how our approach can be used to explore regimes such as the moderate system-environment coupling regime that could not be investigated before in a straightforward manner.

Anomalous EDGES 21-cm Signal and Moduli Dominated Era
Creators: name: Dhuria, Mansi
Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The EDGES collaboration has recently reported the detection of an unexpectedly stronger absorption signal in the global 21-cm spectrum around cosmic red-shift z = 17, resulting in the significant cooling of the primordial gas. The cooling of the gas can be expected to occur by considering the scattering off the baryons by a small fraction of DM carrying a tiny electromagnetic charge (milli-charged DM). However, it turns out the energy density of milli-charged DM obtained by considering thermal annihilation through massless photons will get overproduced in the range of parameters allowed by 21-cm line signal, if there are no new force carriers etc. In this study, we argue that the milli-charged DM particles might get decoupled during matter domination, in case there are moduli present in the theory. Therefore we estimated the value of relic abundance of milli-charged DM by taking into account an early matter dominated era. We found that for the value of modulus mass around m_Φ ~ 10^6TeV, the milli-charged DM particles could actually yield the desired fraction of DM particles for the values of charge and DM required to explain the 21-cm signal. Thus, the problem of an overproduction of the milli-charged DM density in the desirable range of mass and charge of DM can be evaded by considering an early moduli/matter dominated era.

title: While You Are in England: A Novel and Commentary about the Refugees of 1938-40
Creators: name: Lambert, Sonia
Publisher: name: Goldsmiths, University of London
Year: 2024

description: This Creative Writing PhD consists of two parts. The first part is a novel entitled Sea Air, which deals with the Internment of ‘Enemy Aliens’ (most of whom were in fact Jewish refugees) by the British in 1939-40. It is the story of Ludwig and Hilde, who have escaped from Germany to London, where they hope they will be safe. After war breaks out, Ludwig is interned by the British and then deported by ship, while Hilde is sent to Holloway Prison and then to the Isle of Man. The second part is a CriticalCommentary which looks at representations of female refugees to England in three novels published during the Second World War. The Inquest by Robert Neumann, Young Woman of Europe by Ruth Feiner, and Family from Vienna by Eunice Buckley (Rose Allatini) were written in English by German-speaking authors, drawing on their lived experience. The texts show how female refugees were forced to reconstruct their identities on every level. The experience of exile impacted on their relationships, economic circumstances and national and ethnic/religious affiliations, often prompting a reconsideration of the norms and codes by which they previously lived. I discuss these themes with reference to a wartime essay by Hannah Arendt, ‘We Refugees,’and explore the way that these issues have played out in the writing of my own novel.
Deep imaging of Q2112+059: A bright host galaxy but no DLA absorber

description: In a ongoing programme aimed at studying galaxy counterparts of Damped Ly-alpha Absorbers (DLAs) we have obtained high resolution deep I-band imaging data of the field around the z_em = 0.457 BAL QSO Q2112+059. In the literature this QSO is listed to have a candidate DLA at z_abs = 0.2039 along the line of sight. After subtraction of the QSO Point Spread Function (PSF) we detect a galaxy centred on the position of Q2112+059. To help answer whether this galaxy is the DLA or the QSO host galaxy we retrieved a GHRS spectrum of Q2112+059 from the HST-archive. This spectrum shows that there is no Ly-alpha absorption line at z_abs = 0.2039. This fact in combination with the perfect alignment on the sky of the galaxy and Q2112+059 lead us to the conclusion that the galaxy must be the host galaxy of Q2112+059. The host galaxy of Q2112+059 is bright (M_I^obs = -23.6), and has a radial profile well fitted by a {\it modified Hubble + de Vaucouleurs} profile with R_c = 0.5 kpc and R_e = 3.6 kpc. Our results are well in line with the conclusion of earlier work done at lower redshifts, that bright low redshift QSOs preferentially reside in luminous, elliptical galaxies. The host of Q2112+059 is however, despite it's brightness, very compact when compared to early type galaxies at lower redshifts.

description: Idiopathic scoliosis is a lateral deviation of the spine of unknown origin. Initiation and progression of AIS may result from vertebral column overgrowth through a lordo-scoliotic maladaptation of the spine to the subclinical (functional) tether of a relatively short spinal cord. Implications for treatment, however have not yet been derived from the findings as published so far with the exception of spinal manipulation described by Tomaschewski or neurosurgical release of the filum terminale as described by Royo-Salvador. Following the rationale of Tomaschewski external manipulation might influence the ‘flatback’ contracture as found in the lower thoracic area in patients with beginning AIS and have a beneficial effect on the 3D deformity of the spine and trunk. The hypothesis for this pilot investigation was that with the application of ECSWT, the ‘flatback’ contracture as commonly found in the lower thoracic area of patients with AIS can be reduced. Materials and Methods: Inclusion criteria for the study were: Girls with a Cobb angle between 20 and 50° (average 35.3°, SD 9.6), age 12 to 15 years (average 14.1years SD 1.1). The methodology included (1) Surface Topography (FormetricÔ Diers) before, (2) after 5 min in the treatment position without application of ECSWT and (3) after the application of ECSWT. Results: Lateral deviation (RMS = Root Mean Square) and Surface Rotation (RMS) both were consistently reduced after the intervention. The sagittal parameters kyphosis angle and lordosis angle both were consistently increased after the intervention. The results were consistent but not significant. Conclusions: The concept of a functional tethering of the spinal cord in patients with AIS is supported by the results from this investigation. The application of ECSWT in patients with AIS seems to have a beneficial influence on 3D deformity and the subjective feeling of a tensed back. Manipulation of the ‘flatback’ contracture as commonly found in the lower thoracic area may be beneficial as pointed out by Tomaschewski.

description: In this work we present full sets of solutions for rotating charged boson stars with different coupling values. By adopting local comoving coordinates, we are able to find expressions for the effective hydrodynamic quantities of the fluids as seen by this class of observers. We show that not only is the energy density non zero at the center, for the uncharged case it has a local maximum at the core from which it decreases until the point of local minimum where its variation is discontinuous. For the first time, it is reported how rotating boson stars, charged and uncharged, are completely anisotropic fluids featuring three different pressures. Furthermore, the character of the electromagnetic fields is analyzed.

description: The plateau-non-plateau transition in the antiferromagnetic-(ferromagnetic)$_{n}$ polymerized $S=1/2$ XXZ chains under the magnetic field is investigated. The universality class of this transition belongs to the Brezinskii-Kosterlitz-Thouless (BKT) type. The critical points are determined by level spectroscopy analysis of the numerical diagonalization data for $4 \leq p \leq 13$ where $p(\equiv n+1)$ is the size of a unit cell. It is found that the critical strength of ferromagnetic coupling decreases with $p$ for small $p$ but increases for larger enough $p$. It is also found that the plateau for large $p$ is wide enough for moderate values of exchange coupling so that it should be easily observed experimentally. This is in contrast to the plateaus for $p = 3$ chains which are narrow for a wide range of exchange coupling even away from the critical point.

description: Myocardial infarction (MI) affects millions of people worldwide.MI causes massive cardiac cell death and heart function decrease.However, heart tissue cannot effectively regenerate by itself.While stem cell therapy has been considered an effective approach forregeneration, the efficacy of cardiac stem cell therapy remains low due to inferior cell engraftment in the infarcted region. Thisis mainly a result of low cell retention in the tissue and poor cell survival under ischemic, immune rejection and inflammatoryconditions. Various approaches have been explored to improve cell engraftment: increase of cell retention using biomaterials ascell carriers; augmentation of cell survival under ischemic conditions by preconditioning cells, genetic modification of cells, andcontrolled release of growth factors and oxygen; and enhancement of cell survival by protecting cells from excessive inflammationand immune surveillance. In this paper, we review current progress, advantages, disadvantages, and potential solutions of theseapproaches.

description: The leading correction-to-scaling exponent $ω$ for the three-dimensional dilute Ising model is calculated in the framework of the field theoretic renormalization group approach. Both in the minimal subtraction scheme as well as in the massive field theory (resummed four loop expansion) excellent agreement with recent Monte Carlo calculations [Ballesteros H G, et al Phys. Rev. B 58, 2740 (1998)] is achieved. The expression of $ω$ as series in a $\sqrtε$-expansion up to ${\cal O}(ε^2)$ does not allow a reliable estimate for $d=3$.

description: We present detailed evidence for a warm absorber in the Seyfert 1 galaxy MCG--6-30-15 and dispute earlier claims for relativistic O line emission. The HETG spectra show numerous narrow, unresolved (FWHM < 200 km/s) absorption lines from a wide range of ionization states of N, O, Mg, Ne, Si, S, Ar, and Fe. The O VII edge and 1s^2--1snp resonance line series to n=9 are clearly detected at rest in the AGN frame. We attribute previous reports of an apparently highly redshifted O VII edge to the 1s^2--1snp (n > 5) O VII resonance lines, and a neutral Fe L absorption complex. The shape of the Fe L feature is nearly identical to that seen in the spectra of several X-ray binaries, and in laboratory data. The implied dust column density agrees with that obtained from reddening studies, and gives the first direct X-ray evidence for dust embedded in a warm absorber. The O VIII resonance lines and weak edge are also detected, and the spectral rollover below 2 keV is explained by the superposition of numerous absorption lines and edges. We identify, for the first time, a KLL resonance in the O VI photoabsorption cross section, giving a measure of the O VI column density. The O VII (f) emission detected at the systemic velocity implies a covering fraction of ~5% (depending on the observed vs. time-averaged ionizing flux). Our observations show that a dusty warm absorber model is not only adequate to explain all the spectral features > 0.48 keV (< 26 Å) the data REQUIRE it. This contradicts the interpretation of Branduardi-Raymont et al. (2001) that this spectral region is dominated by highly relativistic line emission from the vicinity of the black hole.

The vortex lattice melting theory as example of science fiction

description: The concept of the transition of type II superconductor into the Abrikosov state as the appearance of long-range phase coherence is considered. It is shown that this transition should be first order in ideal (without disorder) superconductor. Such transition is indeed observed in bulk superconductors with weak disorder at a field Hc4 < Hc2. No experimental evidence of the vortex lattice melting exists now. It is shown that this popular concept has appeared on a consequence of an incorrect interpretation of the Abrikosov state and incorrect definition of the phase coherence. The absence of a sharp transition in thin films with weak disorder is interpreted as absence of long-range phase coherence down to very low magnetic field. In order to explain the observed smooth phase coherence appearance in superconductors with strong disorder it is proposed to return to the Mendelssohn model.

description: Density-density response functions are evaluated for nondegenerate multisubband electron systems in the random-phase approximation for arbitrary wave number and subband index. We consider both quasi-two-dimensional and quasi-one- dimensional systems for electrons confined to the surface of liquid helium. The dispersion relations of longitudinal intrasubband and transverse intersubband modes are calculated at low temperatures and for long wavelengths. We discuss the effects of screening and two-subband occupancy on the plasmon spectrum. The characteristic absorption edge of the intersubband modes is shifted relatively to the single-particle intersubband separation and the depolarization shift correction can be significant at high electron densities.

description: The aim of this paper is to analyze the cosmological evolution of holographic dark energy in $f(\mathcal{G},T)$ gravity ($\mathcal{G}$ and $T$ represent the Gauss-Bonnet invariant and trace of the energy-momentum tensor, respectively). We reconstruct $f(\mathcal{G},T)$ model through correspondence scheme using power-law form of the scale factor. The qualitative analysis of the derived model is investigated with the help of evolutionary trajectories of equation of state, deceleration as well as state-finder diagnostic parameters and $ω_{_{\mathcal{G}T}}-ω'_{_{\mathcal{G}T}}$ cosmological phase plane. It is found that the equation of state parameter represents phantom epoch of the Universe whereas the deceleration parameter illustrates the accelerated phase. The state-finder plane corresponds to Chaplygin gas model while the freezing region is attained in $ω_{_{\mathcal{G}T}}-ω'_{_{\mathcal{G}T}}$ plane.

description: We have performed a new search for DPVs of short period in the ASAS catalog (Pojmanski, G., 1997), focusing on those stars with orbital periods between 2 to 3 days which also show variations in their brightness. From a total of 244 objects, we have found another candidate to DPV, one whose mean brightness is gradually decreasing. By fitting a 3rd order polynomial to the mean magnitude and then moving it to zero for a second analysis, a gradual decrease over 2500 days was revealed. During the last 1000 days of this decrease, a 42% increase in the variation between the minimum and maximum values of the magnitude was observed. We determined the orbital period by using the PDM IRAF software (Stellingwerf 1978) and estimated the errors for the orbital period and long cycle by visual inspection of the light curves phased with trial periods near the minimum of the periodogram given by PDM.

X-ray energy and power spectra of Seyfert 1 and Narrow Line Seyfert 1 galaxies: comparison to Black Hole Binaries
Creators: name: Zycki, Piotr T.

Year: 2001
Subjects: subject: Astrophysics (astro-ph)

description: I review observational data on X-ray energy spectra and variability of Seyfert 1 and Narrow Line Seyfert 1 galaxies, and compare them to black hole binary (BHB) systems. There seems to be greater similarity of time averaged properties (i.e. energy spectra) than time variability between the supermassive and stellar-mass black hole accreting systems. Energy spectra of Seyfert 1 galaxies are similar to BHB in low/hard state, but power spectra of Sy 1 are intermediate in properties between those for hard and soft states of BHB. There is growing evidence that NLSy 1 are accreting at higher accretion rates than Sy 1, which supports the view that they correspond to soft states of BHB. Again, they are more similar to their stellar counterparts with respect to their spectral properties than to the timing properties. I briefly outline some theoretical ideas which suggest explanations of those differences.

Symmetry Algebras of Stringy Cosets

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We find the symmetry algebras of cosets which are generalizations of the minimal-model cosets, of the specific form $\frac{SU(N)_{k} \times SU(N)_{\ell}}{SU(N)_{k+\ell}}$. We study this coset in its free field limit, with $k,\ell \rightarrow \infty$, where it reduces to a theory of free bosons. We show that, in this limit and at large $N$, the algebra $\mathcal{W}^e_\infty[1]$ emerges as a sub-algebra of the coset algebra. The full coset algebra is a larger algebra than conventional $\mathcal{W}$-algebras, with the number of generators rising exponentially with the spin, characteristic of a stringy growth of states. We compare the coset algebra to the symmetry algebra of the large $N$ symmetric product orbifold CFT, which is known to have a stringy symmetry algebra labelled the `higher spin square'. We propose that the higher spin square is a sub-algebra of the symmetry algebra of our stringy coset.

description: Although new hepatitis C treatments are a vast improvement on older, interferon-based regimens, there are those who have not taken up treatment, as well as those who have begun but not completed treatment. In this article, we analyse 50 interviews conducted for an Australian research project on treatment uptake. We draw on Berlant’s (2007, Critical Inquiry, 33) work on ‘slow death’ to analyse so-called ‘non-compliant’ cases, that is, those who begin but do not complete treatment or who do not take antiviral treatment as directed. Approached from a biomedical perspective, such activity does not align with the neoliberal values of progress, self-improvement and rational accumulation that pervade health discourses. However, we argue that it is more illuminating to understand them as cases in which sovereignty and agency are neither simplistically individualised nor denied, and where ‘modes of incoherence, distractedness, and habituation’ are understood to co-exist alongside ‘deliberate and deliberative activity […] in the reproduction of predictable life’ (Berlant, 2007, p. 754). The analysed accounts highlight multiple direct and indirect forces of attrition and powerfully demonstrate the socially produced character of agency, a capacity that takes shape through the constraining and exhausting dynamics of life in conditions of significant disadvantage.
