description: Following the paradigm on the sphere, we begin the study of irrational conformal field theory (ICFT) on the torus. In particular, we find that the affine-Virasoro characters of ICFT satisfy heat-like differential equations with flat connections. As a first example, we solve the system for the general $g/h$ coset construction, obtaining an integral representation for the general coset characters. In a second application, we solve for the high-level characters of the general ICFT on simple $g$, noting a simplification for the subspace of theories which possess a non-trivial symmetry group. Finally, we give a geometric formulation of the system in which the flat connections are generalized Laplacians on the centrally-extended loop group.

description: X-ray fiber diffraction experiments on Alzheimer Aβ(1–40) fibrils formed in an assembly process thought to simulate a portion of the pathophysiological process in Alzheimer's disease, indicated protofilaments with tilted β-strands rather than strands oriented perpendicular to the fibril axis as is usually interpreted from cross-β patterns. The protofilament width and tilt angle determined by these experiments were used to predict a β-strip helix model – a β-helix-like structure in which multiple identical polypeptide molecules assemble in-register to form a helical sheet structure such that the outer strands 1 and m join with a register shift t – with m = 11 and t = 22. Starting from untwisted β-sheets comprising 10, 11, and 12 strands, multiple explicit solvent molecular dynamics (MD) simulations were performed to determine whether the sheets form β-strip helices matching the dimensions of the experimentally measured protofilament. In the simulations, the predicted 11-strand sheets curled up to form a closed β-strip helix-like structure with dimensions matching experimental values, whereas the 10- and 12-strand sheets did not form a closed helical structure. The 12-strand structure did, however, show similarity to a cross-β structure determined by a solid-state NMR experiment. The 11-strand β-strip helix resembles a trans-membrane β-barrel which could explain the ability of small oligomers of Aβ(1–40) to form toxic ion channels. A further consequence of opposite sides of the 11-strand strip coming together at a register shift of 22 is end-to-end joins between neighboring β-strip helices, resulting in a protofilament that keeps growing in both directions.

Binary companions of evolved stars in APOGEE DR14: Orbital circularization

description: Short-period binary star systems dissipate orbital energy through tidal interactions that lead to tighter, more circular orbits. When at least one star in a binary has evolved off of the main sequence, orbital circularization occurs for longer-period (~100 day) systems. Past work by (Verbunt & Phinney 1995) has shown that the orbital parameters and the circularization periods of a small sample of binary stars with evolved-star members can be understood within the context of standard tidal circularization theory. Using a sample of binaries with subgiant, giant, and red clump star members that is nearly an order of magnitude larger, we reexamine predictions for tidal circularization of binary stars with evolved members. We confirm that systems predicted by equilibrium-tide theory to have circular orbits generally have negligible measured eccentricities. The circularization period is correlated with the surface gravity (i.e. size) of the evolved member, indicating that the circularization timescale must be shorter than the evolutionary timescale along the giant branch. A few exceptions to the conclusions above are mentioned in the discussion: Some of these exceptions are likely systems in which the spectrum of the secondary biases the radial velocity measurements, but four appear to be genuine, short-period, moderate-eccentricity systems.

description: In this paper we construct manifestly covariant relativistic coherent states on the entire complex plane which reproduce others previously introduced on a given $SL(2,R)$ representation, once a change of variables $z\in C\rightarrow z_D \in $ unit disk is performed. We also introduce higher-order, relativistic creation and annihilation operators, $\C,\Cc$, with canonical commutation relation $[\C,\Cc]=1$ rather than the covariant one $[\Z,\Zc]\approx$ Energy and naturally associated with the $SL(2,R)$ group. The canonical (relativistic) coherent states are then defined as eigenstates of $\C$. Finally, we construct a canonical, minimal representation in configuration space by mean of eigenstates of a canonical position operator.

description: Five groups of 4-substituted phenyl 4ʹ-(2ʺ- (or 3″-) substituted-4ʺ-alkoxyphenylazo) benzoates (Ina-c to Vna-c) were investigated in which, within each group, the length of the terminal alkoxy group varies between 8 and 16 carbons, while the other terminal substituent, X, is a polar group that alternatively changed between the electron-donating CH3O and the electron-withdrawing Br group, in addition to the un-substituted analogue (X = H). The lateral substituent (Y) in the five groups I–V varies, respectively, between H, 3-CH3, 2-CH3, 3-F and 2-F. Their mesophase stabilities were determined by differential scanning calorimetry and phases identified by polarised light microscopy. The two newly prepared groups of compounds (IVna-c and Vna-c) are structurally characterised by infrared, 1H-NMR, mass spectroscopy, thermogravimetric and elemental analyses. Binary phase diagrams were constructed for each pair of isomers from groups IV and V bearing the same wing substituents but the lateral F is attached to different positions (2ʺ or 3″).

description: Using trajectories from acoustically tracked (RAFOS) floats in the Gulf of Mexico, we construct a geography of its Lagrangian circulation within the 1500--2500-m layer. This is done by building a Markov-chain representation of the Lagrangian dynamics. The geography is composed of weakly interacting provinces that constrain the connectivity at depth. The main geography includes two provinces of near equal areas and separated by a roughly meridional boundary. The residence time is about 4.5 (3.5) years in the western (eastern) province. The exchange between these provinces is effected through a slow cyclonic circulation, which is well constrained in the western basin by preservation of $f/H$, where $f$ is the Coriolis parameter and $H$ is depth. Secondary provinces of varied shapes covering smaller areas are identified with residence times ranging from about 0.4 to 1.2 years or so. Except for the main provinces, the deep Lagrangian geography does not resemble the surface Lagrangian geography recently inferred from satellite-tracked drifter trajectories. This implies disparate connectivity characteristics with potential implications for pollutant (e.g., oil) dispersal at the surface and depth. A ventilation conduit through the southeastern corner of the domain from the Caribbean Sea balanced by weak vertical exchange is also inferred. This is supported by the inspection of satellite-tracked profiling (Argo) floats, which, while forming a smaller dataset and having seemingly different water-following characteristics than the RAFOS floats, replicate the main aspects of the Lagrangian geography. Finally, consistency with independent results from a chemical tracer release experiment is found to provide additional support to the results.

In such cases there are inequivalent ways of gauging (generalizing the axial and vector cases for abelian groups) corresponding to external automorphisms of the group. Different $\s$-models obtained this way correspond to the same conformal field theory. We use the method of quotients to formulate this equivalence as a new duality symmetry.

A Low Lyman Continuum Escape Fraction of $<10\%$ for Extreme [OIII] Emitters in an Overdensity at z$\sim3.5$

description: Recent work has suggested extreme [OIII] emitting star-forming galaxies are important to reionization. Relatedly, [OIII]/[OII] has been put forward as an indirect estimator of the Lyman Continuum (LyC) escape fraction ($f_{esc}$) at $z\gtrsim4.5$ when the opaque IGM renders LyC photons unobservable. Using deep archival U-band (VLT/VIMOS) imaging of a recently confirmed overdensity at $z\sim3.5$ we calculate tight constraints on $f_{esc}$ for a sample (N=73) dominated by extreme [OIII] emitters. We find no Lyman Continuum signal ($f_{esc}^{rel} < 6.3^{+0.7}_{-0.7} \%$ at $1σ$) in a deep U-band stack of our sample (31.98 mag at 1$σ$). This constraint is in agreement with recent studies of star-forming galaxies spanning $z\sim1-4$ that have found very low average $f_{esc}$. Despite the galaxies in our study having an estimated average rest-frame EW([OIII]$\lambda5007$)$\sim400Å$ and [OIII]/[OII]$\sim 4$ from composite SED-fitting, we find no LyC detection, which brings into question the potential of [OIII]/[OII] as an effective probe of the LyC--a majority of LyC emitters have [OIII]/[OII]$>3$, but we establish here that [OIII]/[OII]$>3$ does not guarantee significant LyC leakage for a population. Since even extreme star-forming galaxies are unable to produce the $f_{esc}\sim10-15\%$ required by most theoretical calculations for star-forming galaxies to drive reionization, there must either be a rapid evolution of $f_{esc}$ between $z\sim3.5$ and the Epoch of Reionization, or hitherto observationally unstudied sources (e.g. ultra-faint low-mass galaxies with $\log(M/M_\odot)\sim7-8.5$) must make an outsized contribution to reionization.

description: Computing reactive trajectories and free energy (FE) landscapes associated to rare event kinetics is key to understanding the dynamics of complex systems. The analysis of the FE surface on which the underlying dynamics takes place has become central to compute transition rates. In the overdamped limit, most often encountered in biophysics and soft condensed matter, the Kramers' Theory (KT) has proved to be quite successful in recovering correct kinetics. However, the additional calculation to obtain rate constants in complex systems where configurational entropy is competing with energy is still challenging conceptually and computationally. Building on KT and the metadynamics framework, the rate is expressed in terms of the height of the FE barrier measured along the minimum FE path and an auxiliary measure of the configurational entropy. We apply the formalism to two different problems where our approach shows good agreement with simulations and experiments and can present significant improvement over the standard KT.

Changing Lives and Livelihoods: Culture, Capitalism and Contestation over Marine Resources in Island Melanesia
Creators: name: Kinch, Jeffrey
Publisher: name: The Australian National University
Year: 2020

description: TThis thesis is both a contemporary and a longitudinal ethnographic case study of Brooker Islanders. Brooker Islanders are a sea-faring people that inhabit a large marine territory in the West Calvados Chain of the Louisiade Archipelago in Milne Bay Province of Papua New Guinea. In the late 19th Century, Brooker Islanders began to be incorporated into an emerging global economy through the production of various marine resources that were desired by mainly Australian capitalist interests. The most notable of these commodified marine resources was beche-de-mer. Beche-de-mer is the processed form of several sea cucumber species. The importance of the sea cucumber fishery for Brooker Islanders waned when World War I started. Following the rise of an increasingly affluent China in the early 1990s, the sea cucumber fishery and beche-de-mer trade once again became an important source of cash income for Brooker Islanders. With an increasing dependency on cash and a subsequent decline in sea cucumber stocks, a number of conflicts emerged across the Louisiade Archipelago due to competition to access areas that still held sea cucumbers stocks. In October 2009, the National Fisheries Authority imposed a moratorium on the sea cucumber fishery and beche-de-mer trade. This moratorium remained in place until April 2017. This moratorium caused major impacts on Brooker Islander livelihoods. Brooker Islanders have limited alternative income opportunities available and also have to contend with regular environmental shocks such as cyclones and El Nino associated droughts. An increasing population and projected impacts of climate change make for a very uncertain future for Brooker Islanders. This thesis is based on anthropological fieldwork, historical research and continued contact with Brooker Islanders that now spans a 22-year period from 1998 to the present. Using a historical political ecology approach, I argue that the incorporation of Brooker Islanders into the global economy and the unevenness of development has produced profound changes in their livelihoods, local marine tenureship arrangements and social relations with their island neighbours. This thesis provides a case study of the role that capitalism plays in changing livelihoods and institutions over time when market opportunities arise and consumer dependencies become essential to maintaining livelihoods. The contestation over commodified marine resources is also viewed in the context of changing political and legal domains. Issues of governability for the sustainability of sea cucumber stocks are also explored.

description: The appealing feature of inverse seesaw models is that the Standard Model (SM) neutrino mass emerges from the exchange of TeV scale singlets with sizable Yukawa couplings, which can be tested at colliders. However, the tiny Majorana mass splitting between TeV singlets, introduced to accommodate small neutrino masses, is left unexplained. Moreover, we argue that these models suffer from a structural limitation that prevents a successful leptogenesis if one insists on having unsuppressed Yukawa couplings and TeV scale singlets. In this work we propose a hybrid seesaw model, where we replace the mass splitting with a coupling to a high scale seesaw module including a TeV scalar. We show that this structure achieves the goal of filling both the above gaps with couplings of order unity. The necessary structure automatically arises embedding the seesaw mechanism in composite Higgs models, but may also be enforced by new gauge symmetries in a weakly-coupled theory. Our hybrid seesaw models have distinguishing features compared to the standard high scale type-I seesaw and inverse seesaw. Firstly, they have much richer phenomenology. Indeed, they generally predict new TeV scale physics (including scalars) potentially accessible at present and future colliders, whereas weakly-coupled versions may also have astrophysical and cosmological signatures due to the presence of a light Nambu-Goldstone boson coupled to neutrinos. Secondly, our scenario features an interesting interplay between high scale and TeV scale physics in leptogenesis and enlarges the range of allowed high scale singlet masses beyond the usual $\sim 10^9-10^{ 15 }$ GeV, without large hierarchies in the Yukawa couplings nor small mass splitting among the singlets.

description: The novel triphenylene-Bodipy derivatives 6 and 7 based on 1,3,5-triazine core were designed and synthesised by introducing BODIPY unit and triphenylene units sequentially onto cyanuric chloride. The Bodipy derivative 6 with one triphenylene unit was a nematic liquid crystal but the derivative 7 with two triphenylene units was a hexagonal columnar liquid crystal. The investigation on photophysical properties suggested that both of them exhibited excellent fluorescence with high fluorescence quantum yields and the Stokes shifts were larger than their Bodipy precursors. This research presented a good example of design and synthesis of columnar Bodipy liquid crystal with high fluorescence and large Stokes shift.

description: We report the enhancement in the molecular ordering of ferroelectric liquid crystal (FLC) doped with CdSe/ZnSe graded core/shell (CZ) quantum dots (QDs) by using optical methods. Significant decrease in operating voltage and enhancement in optical brightness are assigned to the large primary order parameter (θ) and hence anchoring of FLC molecules by CZ QDs. The enhancement in photoluminescence is conjectured to be due to an increase in molecular alignment yielding higher absorption which is confirmed by excitation spectra. These observations would definitely offer a promising tool to get superior core/shell QD incorporated FLC-based display devices.

description: X-ray fibre diffraction experiments on Alzheimer Aβ(1-40) fibrils (Fraser et al. Biochemistry 31, 1992; Malinchik et al. Biophysical Journal, 74, 1998) indicated protofilaments with tilted β-strands rather than strands oriented perpendicular to the fibril axis as is usually interpreted from cross-β patterns. The protofilament width and tilt angle determined by these experiments were used to predict a β-strip helix model – a β-helix-like structure in which multiple identical polypeptide molecules assemble in-register to form a helical sheet structure such that the outer strands 1 and m join with a register shift t – with m = 11 and t = 22. Starting from untwisted β-sheets comprising 10, 11 and 12 strands, multiple explicit solvent Molecular Dynamics simulations were performed to determine whether the sheets form β-strip helices matching the dimensions of the experimentally measured protofilament. In the simulations, the predicted 11-strand sheets curled up to form a closed β-strip helix like structure with dimensions matching experimental values, whereas the 10- and 12-strand sheets did not form a closed helical structure. However, the 12-strand structure did show similarity to a cross-β structure determined by a solid-state NMR experiment. The 11-strand β-strip helix resembles a trans-membrane β-barrel which could explain the ability of small oligomers of Aβ(1-40) to form toxic ion channels. A further consequence of opposite sides of the 11-strand strip coming together at a register shift of 22 is end-to-end joins between neighbouring β-strip helices, resulting in a protofilament that keeps growing in both directions.

description: We use the quantum symmetries present in string compactification on Landau-Ginzburg orbifolds to prove the existence of a large class of exactly marginal (0,2) deformations of (2,2) superconformal theories. Analogous methods apply to the more general (0,2) models introduced in \DK, lending further credence to the fact that the corresponding \LG\ models represent bona-fide (0,2) SCFTs. We also use the large symmetry groups which arise when the worldsheet superpotential is turned off to constrain the dependence of certain correlation functions on the untwisted moduli. This allows us to approach the problem of what happens when one tries to deform away from the \LG\ point. In particular, we find that the masses and three-point couplings of the massless $E_{6}$ singlets related to ${\rm H^{1}}(\ET)$ vanish at all points in the quintic \Ka\ moduli space. Putting these results together, and invoking some plausible dynamical assumptions about the corresponding linear \sm s, we show that one can deform these \LG\ theories to arbitrary values of the \Ka\ moduli.

description: We use ALMA observations of four sub-millimetre galaxies (SMGs) at $z\sim2-3$ to investigate the spatially resolved properties of the inter-stellar medium (ISM) at scales of 1--5 kpc (0.1--0.6$''$). The velocity fields of our sources, traced by the $^{12}$CO($J$=3-2) emission, are consistent with disk rotation to first order, implying average dynamical masses of $\sim$3$\times10^{11}$M$_{\odot}$ within two half-light radii. Through a Bayesian approach we investigate the uncertainties inherent to dynamically constraining total gas masses. We explore the covariance between the stellar mass-to-light ratio and CO-to-H$_{2}$ conversion factor, $α_{\rm CO}$, finding values of $α_{\rm CO}=1.1^{+0.8}_{-0.7}$ for dark matter fractions of 15 \%. We show that the resolved spatial distribution of the gas and dust continuum can be uncorrelated to the stellar emission, challenging energy balance assumptions in global SED fitting. Through a stacking analysis of the resolved radial profiles of the CO(3-2), stellar and dust continuum emission in SMG samples, we find that the cool molecular gas emission in these sources (radii $\sim$5--14 kpc) is clearly more extended than the rest-frame $\sim$250 $μ$m dust continuum by a factor $>2$. We propose that assuming a constant dust-to-gas ratio, this apparent difference in sizes can be explained by temperature and optical-depth gradients alone. Our results suggest that caution must be exercised when extrapolating morphological properties of dust continuum observations to conclusions about the molecular gas phase of the ISM.

description: Exploiting the efficiency and stability of Position-Based Dynamics (PBD), we introduce a novel crowd simulation method that runs at interactive rates for hundreds of thousands of agents. Our method enables the detailed modeling of per-agent behavior in a Lagrangian formulation. We model short-range and long-range collision avoidance to simulate both sparse and dense crowds. On the particles representing agents, we formulate a set of positional constraints that can be readily integrated into a standard PBD solver. We augment the tentative particle motions with planning velocities to determine the preferred velocities of agents, and project the positions onto the constraint manifold to eliminate colliding configurations. The local short-range interaction is represented with collision and frictional contact between agents, as in the discrete simulation of granular materials. We incorporate a cohesion model for modeling collective behaviors and propose a new constraint for dealing with potential future collisions. Our new method is suitable for use in interactive games.

Quantum Symmetries and Stringy Instantons

description: The quantum symmetry of many \LG\ orbifolds appears to be broken by Yang-Mills instantons. However, isolated Yang-Mills instantons are not solutions of string theory: They must be accompanied by gauge anti-instantons, gravitational instantons, or topologically non-trivial configurations of the $H$ field. We check that the configurations permitted in string theory do in fact preserve the quantum symmetry, as a result of non-trivial cancellations between symmetry breaking effects due to the various types of instantons. These cancellations indicate new constraints on \LG\ orbifold spectra and require that the dilaton modulus mix with the twisted moduli in some \LG\ compactifications. We point out that one can find similar constraints at all fixed points of the modular group of the moduli space of vacua.

Gauge Invariance and Second Class Constraints in 3-D Linearized Gravity

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

description: A recently introduced approach for the dynamical analysis and quantization of field theoretical models with second class constraints is ilustrated applied to linearized gravity in 3-D. The canonical structure of two different models of linerized gravity in 3-D, the intermediate and the self dual models, is discussed in detail. It is shown that the first order self dual model whose constraints are all second class may be regarded as a gauge fixed version of the second order gauge invariant intermediate model. In particular it is shown how to construct the gauge invariant hamiltonian of the intermediate model starting from the one of the self dual model. The relation with the t opologically massive linearized gravity is also discussed.

description: Samarium hexaboride is a topological Kondo insulator, with metallic surface states manifesting from its insulating band structure. Since the insulating bulk itself is driven by strong correlations, both the bulk and surface host compelling magnetic and electronic phenomena. We employed X-ray absorption spectroscopy (XAS) and X-ray magnetic circular dichroism (XMCD) at the Sm M$_{4,5}$ edges to measure surface and bulk magnetic properties of Sm$^{2+}$ and Sm$^{3+}$ within SmB$_6$. We observed anti-alignment to the applied field of the Sm$^{3+}$ magnetic dipole moment below $T = 75$ K and of the total orbital moment of samarium below 30 K. The induced Sm$^{3+}$ moment at the cleaved surface at 8 K and 6 T implies 1.5% of the total Sm as magnetized Sm$^{3+}$. The field dependence of the Sm$^{3+}$ XMCD dichorism at 8 K is diamagnetic and approximately linear. The bulk magnetization at 2 K is however driven by Sm$^{2+}$ Van Vleck susceptibility as well as 1% paramagnetic impurities with $μ_{\rm Eff} = 5.2(1)~μ_{\rm B}$. This indicates diamagnetic Sm$^{3+}$ is compensated within the bulk. The XAS and XMCD spectra are weakly affected by Sm vacancies and carbon doping while XAS is strongly affected by polishing.
Putin’s Mini-Armies: The Chechen Kadyrovites

Publisher: name: Pericles Institute

description: Chechnya may soon become a larger player in the international field. Instead of over-focusing on Russia, the United States needs to keep an eye on Chechnya’s moves. Claims that Chechnya may again enter conflict against Russia have gained validity in the past decade. Kadyrov presents a present danger to Western interests and attention must be diverted to watching these smaller factions for exploitable signs of dissent against Russia. NATO and other international organizations should move to exploit potential divisions in the Russian system, like Chechnya and the Kadyrovites, without empowering Chechen fighters to commit additional human rights violations in Eurasia and around the world.

description: This essay explores the cultural and scientific significance of stereoscopic photography, focusing on its role as both an optical illusion and a philosophical toy in the 19th century. It examines the contributions of Sir Charles Wheatstone, David Brewster, and Jules Duboscq in refining stereoscopic technology and its widespread adoption in Victorian society. The essay also discusses the stereoscope’s influence on visual culture, its function as a medium for virtual travel, and its impact on perceptions of reality. Special attention is given to Jersey’s engagement with stereoscopy, highlighting historical advertisements and commercial practices that shaped public interaction with this technology. Through a critical lens, the study considers stereography’s role in constructing narratives and reinforcing ideological frameworks, reflecting both the scientific curiosity and social contradictions of its time.
