description: Living systems use chemical fuel to process information, assemble structures and maintain fluxes. Many of these processes are dissipative: energy is consumed purely to maintain non-equilibrium steady-state outputs. How efficiently the input energy is transduced toward the output dissipation as opposed to being lost during intermediate steps, and whether the efficiency is constrained by general principles or specific fine-tuning, are open questions. Here, applying a recent mapping from non-equilibrium systems to battery-resistor circuits, an analytic expression for the efficiency of any dissipative molecular machine driven by a chemical potential difference is derived. This expression disentangles the chemical potential from the machine’s details, whose effect on the efficiency is fully specified by a constant called the load resistance. The efficiency passes through an inflection point separating totally inefficient machines from efficient machines if the balance between chemical potential difference and load resistance exceeds thermal noise. This explains all-or-none dynein stepping with increasing ATP concentration observed in single-molecule experiments. These results indicate that energy transduction in living systems is efficient not because of idiosyncratic optimization of biomolecules, but rather because the concentration of chemical fuel is kept above a threshold level.

description: Auch der 2014 veröffentlichte Comic „Irmina“, um den es hier gehen soll, entworfen und gezeichnet von der Berliner Comic-Autorin Barbara Yelin, behandelt eine Familiengeschichte im Deutschland der 1930er- und 40er-Jahre. „Irmina“ basiert auf Tagebüchern und Briefen ihrer Großmutter, auf die die Autorin vor einigen Jahren gestoßen ist. Wie nah die Geschichte sich an diesen Aufzeichnungen orientiert, bleibt offen, deutlich wird aber, dass dem Buch ausführliche historische Recherchen zugrunde liegen. Dabei nutzt Yelin, wie ich darlegen möchte, genau jene Potenziale des Comics, die das Medium für die Geschichtsschreibung bereithält.

description: Axion-like particles (ALPs) are ubiquitous in models of new physics explaining some of the most pressing puzzles of the Standard Model. However, until relatively recently, little attention has been paid to its interplay with flavour. In this work, we study in detail the phenomenology of ALPs that exclusively interact with up-type quarks at the tree-level, which arise in some well-motivated ultra-violet completions such as QCD-like dark sectors or Froggatt-Nielsen type models of flavour. Our study is performed in the low-energy effective theory to highlight the key features of these scenarios in a model independent way. We derive all the existing constraints on these models and demonstrate how upcoming experiments at fixed-target facilities and the LHC can probe a vast region of the parameter space, which is currently not excluded by cosmological and astrophysical bounds. We also emphasize how a future measurement of the currently unavailable meson decay $D \to π+ \rm{invisible}$ could complement these upcoming searches and help to probe a large unexplored region of their parameter space.

description: Finding and elucidating the properties of Lyman-continuum(LyC)-emitting galaxies is an important step for our understanding of cosmic reionization. Although the z - 0.3-0.4 LyC emitters found recently show strong optical emission lines, no consistent quantitative photoionization model taking into account the escape of ionizing photons and inhomogenous interstellar medium (ISM) geometry of these galaxies has yet been constructed. We hence construct one- and two-zone photoionization models accounting for the observed LyC escape, which we compare to the observed emission line measurements. We find that one-zone density-bounded photoionization models cannot reproduce the emission lines of the LyC leakers because they systematically underpredict the lines of species of low ionization potential, as [OI] and [SII]. Introducing a two-zone model, with differing ionization parameter and a variable covering fraction and where one of the zones is density-bounded, we show that the observed emission line ratios and escape fractions of the LyC emitters are well reproduced. The [OI] excess, which is observed in some LyC leakers, can be naturally explained in this model, e.g., by emission from low-ionization and low-filling-factor gas. LyC emitters with a high escape fraction (fesc > 38%) are deficient both in [OI]6300A and in [SII]6716,6731A. We also confirm that a [SII] deficiency can be used to select LyC emitter candidates. Finally, we find indications for a possible dichotomy in terms of escape mechanisms for LyC photons between galaxies with relatively low (fesc < 10%) and higher escape fractions. We conclude that two-zone photoionization models are sufficient and required to explain the observed emission line properties of z - 0.3-0.4 LyC emitters. These models provide a first step towards the use of optical emission lines and their ratios as quantitative diagnostics of LyC escape from galaxies.

Effect of exercise on three-equation D[sub L]CO in sarcoidosis and idiopathic pulmonary fibrosis
Creators: name: Rai, Sundeep
Publisher: name: University of British Columbia
Year: 2009

description: Impairment in CO pulmonary diffusing capacity (D[sub L]CO) may be a factor limiting exercise in interstitial lung disease (ILD). We used the three-equation D[sub L]CO (D[sub L]CO[sub 3EQ]) method to measure single breath D[sub L]CO during exercise to determine whether limited ability of D[sub L]CO to increase during exercise is related to exercise induced hypoxemia in two different ILD, idiopathic pulmonary fibrosis (IPF), and sarcoidosis. The D[sub L]CO[sub 3EQ] technique involves continuous monitoring of exhaled CO and an inert tracer gas and accounts for CO uptake during the inhalation, breath holding, and exhalation phases of a breathing maneuver. This technique determines D[sub L]CO without requiring breath holding, allowing its use in patients with ILD during exercise. In 15 patients with ILD (8 sarcoidosis and 7 IPF) and 7 normal, healthy subjects, we determined D[sub L]CO[sub 3EQ] at rest and during 2 levels of steady state exercise, 35% and 70% of the previously determined maximal power output. From rest to the 70% level of exercise, D[sub L]CO[sub 3EQ] (units in mL⋅min⁻¹⋅mmHg⁻¹ and in % predicted D[sub L]CO[sub SB] at rest) increased from 34.6+SE 2.7 (118%) to 48.7+SE 4.0 (164%) in control subjects, from 23.0 +SE 2.8 (86%) to 33.8 +SE 3.8 (126%) in sarcoidosis, and from 15.9 +SE 0.7 (67%) to 20.5 +SE 0.8 (87%) in the IPF patients. The % increase in D[sub L]CO[sub 3EQ] for a given increase in VO₂ expressed as % of maximal predicted, was smaller in the IPF group when compared to both the sarcoidosis (p<0.0001) and the control groups (p<0.01). In the IPF patients, O₂ saturation by pulse oximetry decreased markedly from rest (96+SE 0.3%, n=7) to 88+SE 1.8% at the 70% level of exercise, and was associated with severe arterial hypoxemia (mean P[sub a]O₂ 52±SE 2 mmHg, n=4) and a widened A-a O₂ gradient (63+SE 2 mmHg, n=4), whereas the controls and sarcoidosis maintained O₂ saturation. We estimated that 37+SE 6% (n=6) of the A-a O₂ gradient during exercise in IPF was due to diffusion limitation, assuming a constant venous admixture at rest and during exercise.

description: High volume integration of renewable energy like large offshore wind power plants (OWPP) has pushed the modern power system closer to its critical dynamic stability limits due to its inherent variability & availability uncertainty, decoupling due to power electronics interface and system-expansion constraints. Thus, an improper handling of certain partial failures can easily lead to severe chain reactions, which ultimately increases the risk of wide area blackouts due to stronger linking of national power systems. In contrast to conventional blackstart units (BSU), large OWPPs can provide fast and fully controlled, high power, environment-friendly blackstart capability. Moreover, grid-forming wind turbines (WT) need not only wait for network restoration to complete like traditional grid-following WTs, but can also participate & support the network energization & load restoration process in the earlier stages, thus reducing the overall impact of a blackout. Additionally, blackstart-able WTs can produce power to sustain themselves and avoid risk to their health, especially when offline for long durations. This minimizes the use of diesel generator and provides cost benefit. Since, grid-forming is a necessary capability for WTs to support the blackstart restoration process, this paper aims at presenting a conceptual classification of the various existing grid forming control strategies. The different control techniques that will be studied are virtual synchronous machine based (VISMA, VSM), power synchronization control (PSC, Synchronverter), Distributed PLL-based, direct power control (DPC, enhanced DPC) and Synchronous machine matching. Furthermore, the different control techniques will be implemented in an aggregated wind farm model for comparison in the scope of blackstart restoration and islanding operation using OWPPs. The main aim of this study will be to ensure controlled network energization and stable load recovery of the offshore collector grid for durations sufficiently long enough that OWPPs be considered as BSUs by TSO for early participation in power system restoration.

description: The origin and micro-texture of ooids remain controversial. This study presents a review of microstructure of ooids and explains the origin of microstructures in Cambrian ooids in the North China Platform. Factors controlling the morphology and mineral composition of ooid are very complex. Ooids form by a combination of physical, chemical and biological processes, in various environments. Recent studies on modern Bahamian ooids and laboratory experiments with microbial cultures highlight the formation of ooids without detailed explanation of the role of amorphous calcium carbonate (ACC). This review reinforces the biochemical hypothesis for the origin of ooids and proposes the sequence of microbial activities that involves the active and stationary stages in its formation. Microbes, particularly the filamentous fossils of calcified sheath of cyanobacteria, excrete extracellular polymeric substances (EPS) that act as a template for the formation of ACC. The dark micrite bands, dominated by filamentous cyanobacteria within the cortex and the core of the Cambrian pelagic and benthic ooids of the North China Platform supports the biochemical origin of ooid formation.

We use neutrons from a Cf-252 source to create low-momentum nuclear recoils in elastic scattering with the residual gas nuclei. The recoil track is imaged in low-pressure time-projection chamber with optical readout. We measure the ionization rate along the recoil trajectory, which allows us to determine the direction tag of the incoming neutrons.

We show that the two geometries coincide and we extract, using holographic relations, information about the CFT living on the 1-brane. Finally, we show that the quantum black hole has the same temperature of the bulk BTZ, as expected from the holographic principle.

description: We outline a formalism and develop a computational procedure to treat the process of multiphoton ionization (MPI) of atomic targets in strong laser fields. We treat the MPI process nonperturbatively as a decay phenomenon by solving a coupled set of the integral Lippmann-Schwinger equations. As basic building blocks of the theory we use a complete set of field-free atomic states, discrete and continuous. This approach should enable us to provide both the total and differential cross-sections of MPI of atoms with one or two electrons. As an illustration, we apply the proposed procedure to a simple model of MPI from a square well potential and to the hydrogen atom.

description: Dempster-Shafer Theory (DST) generalizes Bayesian probability theory, offering useful additional information, but suffers from a much higher computational burden. A lot of work has been done to reduce the time complexity of information fusion with Dempster's rule, which is a pointwise multiplication of two zeta transforms, and optimal general algorithms have been found to get the complete definition of these transforms. Yet, it is shown in this paper that the zeta transform and its inverse, the Möbius transform, can be exactly simplified, fitting the quantity of information contained in belief functions. Beyond that, this simplification actually works for any function on any partially ordered set. It relies on a new notion that we call focal point and that constitutes the smallest domain on which both the zeta and Möbius transforms can be defined. We demonstrate the interest of these general results for DST, not only for the reduction in complexity of most transformations between belief representations and their fusion, but also for theoretical purposes. Indeed, we provide a new generalization of the conjunctive decomposition of evidence and formulas uncovering how each decomposition weight is tied to the corresponding mass function.

description: We study the changes in the short-distance quark structure of the Nambu-Goldstone boson when the long-distance symmetry-breaking scales are depleted controllably. We achieve this by studying the valence Parton Distribution Function (PDF) of pion in 2+1 dimensional two-color QCD, with the number $N$ of massless quarks as the tunable parameter that slides the theory from being strongly broken for $N=0$ to the conformal window for $N>4$, where the theory is gapped by the fixed finite volume. We perform our study non-perturbatively using lattice simulations with $N=0,2,4,8$ flavors of nearly massless two-component Wilson-Dirac sea quarks and employ the leading-twist formalism (LaMET/SDF) to compute the PDF of pion at a fixed valence mass. We find that the relative variations in the first few PDF moments are only mild compared to the changes in decay constant, but the shape of the reconstructed $x$-dependent PDF itself dramatically changes from being broad in the scale-broken sector to being sharply peaked in the near-conformal region, best reflected in PDF shape observables such as the cumulants.

description: We study the large momentum limit of the monster potentials of Bazhanov-Lukyanov-Zamolodchikov, which -- according to the ODE/IM correspondence -- should correspond to excited states of the Quantum KdV model. We prove that the poles of these potentials asymptotically condensate about the complex equilibria of the ground state potential, and we express the leading correction to such asymptotics in terms of the roots of Wronskians of Hermite polynomials. This allows us to associate to each partition of $N$ a unique monster potential with $N$ roots, of which we compute the spectrum. As a consequence, we prove -- up to a few mathematical technicalities -- that, fixed an integer $N$, the number of monster potentials with $N$ roots coincides with the number of integer partitions of $N$, which is the dimension of the level $N$ subspace of the quantum KdV model. In striking accordance with the ODE/IM correspondence.

description: Magnetic excitations of the filled skutterudite PrRu4P12 exhibiting a metal-insulator (M-I) transition at TM-I= 63 K were studied by inelastic neutron scattering experiment. The spectra at temperatures much lower than TM-I are described as well-defined crystal-field excitations. With approaching TM-I, the excitation peaks broaden and shift considerably together with the temperature variation of the carrier number and the atomic displacement in the transition. The 4f-electron state evolve from the well localized state in the insulator phase to the strongly hybridized itinerant state by p-f mixing near TM-I. The hybridization is responsible for the M-I transition of PrRu4P12.

description: Geometrically frustrated materials, such as spin ice or kagome lattice, are known to exhibit exotic Hall effect phenomena due to spin chirality. We explore Hall effect mechanism in an artificial honeycomb spin ice of Nd--Sn element using Hall probe and polarized neutron reflectivity measurements. In an interesting observation, a strong enhancement in Hall signal at relatively higher temperature of $T$ $\sim$ 20 K is detected. The effect is attributed to the planar Hall effect due to magnetic moment configuration in spin ice state in low field application. In the antiferromagnetic state of neodymium at low temperature, applied field induced coupling between atomic Nd moments and conduction electrons in underlying lattice causes distinct increment in Hall resistivity at very modest field of $H$ $\sim$ 0.015 T. The experimental findings suggest the development of a new research vista to study the planar and the field induced Hall effects in artificial spin ice.

description: Bell proved that quantum entanglement enables two space-like separated parties to exhibit classically impossible correlations. Even though these correlations are stronger than anything classically achievable, they cannot be harnessed to make instantaneous (faster than light) communication possible. Yet, Popescu and Rohrlich have shown that even stronger correlations can be defined, under which instantaneous communication remains impossible. This raises the question: Why are the correlations achievable by quantum mechanics not maximal among those that preserve causality? We give a partial answer to this question by showing that slightly stronger correlations would result in a world in which communication complexity becomes trivial.

description: Concern has grown in recent years over the seismic activity of the New Madrid seismic zone in Western Kentucky. Western Kentucky is located in this region. To permit emergency medical, supply, and equipment traffic into this area after an earthquake has occurred, the Kentucky Transportation Cabinet is interested in the possibility of keeping selected routes passable. This report lists the routes that have been investigated and recommended as being the routes in Northern Tennessee that should be maintained in a passable condition. The recommended routes, US 79, US 41A, The Trace and US 641 have been visually surveyed and all seismically significant features cataloged. These features are logged by their location on strip maps contained in Appendix A and a detailed listing of all the potentially critical features is given in Appendix B.

description: We investigate the generalized second law of thermodynamics (GSL) in generalized theories of gravity. We examine the total entropy evolution with time including the horizon entropy, the non-equilibrium entropy production, and the entropy of all matter, field and energy components. We derive a universal condition to protect the generalized second law and study its validity in different gravity theories. In Einstein gravity, (even in the phantom-dominated universe with a Schwarzschild black hole), Lovelock gravity, and braneworld gravity, we show that the condition to keep the GSL can always be satisfied. In $f(R)$ gravity and scalar-tensor gravity, the condition to protect the GSL can also hold because the gravity is always attractive and the effective Newton constant should be approximate constant satisfying the experimental bounds.

description: We construct admissible circulant Laplacian matrix functions as generators for strictly increasing random walks on the integer line. These Laplacian matrix functions refer to a certain class of Bernstein functions. The approach has connections with biased walks on digraphs. Within this framework, we introduce a space-time generalization of the Poisson process as a strictly increasing walk with discrete Mittag-Leffler jumps subordinated to a (continuous-time) fractional Poisson process. We call this process `{\it space-time Mittag-Leffler process}'. We derive explicit formulae for the state probabilities which solve a Cauchy problem with a Kolmogorov-Feller (forward) difference-differential equation of general fractional type. We analyze a `well-scaled' diffusion limit and obtain a Cauchy problem with a space-time convolution equation involving Mittag-Leffler densities. We deduce in this limit the `state density kernel' solving this Cauchy problem. It turns out that the diffusion limit exhibits connections to Prabhakar general fractional calculus. We also analyze in this way a generalization of the space-time fractional Mittag-Leffler process. The approach of construction of good Laplacian generator functions has a large potential in applications of space-time generalizations of the Poisson process and in the field of continuous-time random walks on digraphs.

description: Given $α> -1$, consider the second order differential operator in $(0,\infty)$, $$L_αf \equiv (x^2 \frac{d^2}{dx^2} + (2α+3)x \frac{d}{dx} + x^2 + (α+1)^2)(f), $$ which appears in the theory of Bessel functions. The purpose of this paper is to develop the corresponding harmonic analysis taking $L_α$ as the analogue to the classical Laplacian. Namely we study the boundedness properties of the heat and Poisson semigroups. These boundedness properties allow us to obtain some convergence results that can be used to solve the Cauchy problem for the corresponding heat and Poisson equations.

description: In the star formation process, the vital impact of environmental factors such as feedback from massive stars and stellar density on the form of the initial mass function (IMF) at low-mass end is yet to be understood. Hence a systematic, highly sensitive observational analysis of a sample of regions under diverse environmental conditions is essential. We analyse the IMF of eight young clusters ($

Breaking chirality in nonequilibrium systems on the lattice

description: We study the dynamics of fronts in parametrically forced oscillating lattices. Using as a prototypical example the discrete Ginzburg-Landau equation, we show that much information about front bifurcations can be extracted by projecting onto a cylindrical phase space. Starting from a normal form that describes the nonequilibrium Ising-Bloch bifurcation in the continuum and using symmetry arguments, we derive a simple dynamical system that captures the dynamics of fronts in the lattice. We can expect our approach to be extended to other pattern-forming problems on lattices.

Abstract: High-performance data centers are increasingly bottlenecked by the energy and communications costs of interconnecting numerous compute and memory resources. Current systems face a gap of nearly two orders of magnitude between on-chip, intra-socket, communication capacities, and the capacities of links transporting data over longer distances. The per bit energy cost of data movement dominates that of data processing, as does density, throughput, and latency. Integrated silicon photonics offer the opportunity of optical connectivity that delivers high off-chip communication bandwidth densities with low power consumption. To realize these benefits deeply embedded packaging of photonics with the compute and memory is critical. This talk will cover these multi-chip packaging challenges as well as approaches for leveraging dense wavelength-division multiplexing photonic IO that can scale to realize Petabit/s chip escape bandwidths with sub-picojoule/bit energy consumption.

description: Data-driven solutions for the investment industry require event-based backend systems to process high-volume financial data feeds with low latency, high throughput, and guaranteed delivery modes. At vwd we process an average of 18 billion incoming event notifications from 500+ data sources for 30 million symbols per day and peak rates of 1+ million notifications per second using custom-built platforms that keep audit logs of every event. We currently assess modern open source event-processing platforms such as Kafka, NATS, Redis, Flink or Storm for the use in our ticker plant to reduce the maintenance effort for cross-cutting concerns and leverage hybrid deployment models. For comparability and repeatability we benchmark candidates with a standardized workload we derived from our real data feeds. We have enhanced an existing light-weight open source benchmarking tool in its processing, logging, and reporting capabilities to cope with our workloads. The resulting tool wrench can simulate workloads or replay snapshots in volume and dynamics like those we process in our ticker plant. We provide the tool as open source. As part of ongoing work we contribute details on (a) our workload and requirements for benchmarking candidate platforms for financial feed processing; (b) the current state of the tool wrench.

description: The cosmological variability of alpha is probed from individual observations of pairs of FeII lines. This procedure allows a better control of the systematics and avoids the influence of the spectral shifts due to ionization inhomogeneities in the absorbers and/or non-zero offsets between different exposures. Applied to the FeII lines of the metal absorption systems at zabs = 1.839 in Q1101--264 and at zabs = 1.15 in HE0515--4414 observed by means of UVES at the ESO-VLT, it provides da/a = 0.4 (+/- 1.5 stat)x10^{-6}. The result is shifted with respect to the Keck/HIRES mean da/a = -5.7(+/- 1.1 stat})x10^{-6} (Murphy et al. 2004) at a high confidence level (95%). Full details of this work are given in Levshakov et al (2005)
