description: In systems such as block copolymer mesophases or physical gels formed by associating copolymers, the dynamical properties are often controlled by the extraction/association of a sticking group. We propose a description of the extraction/association process of a single sticker. The statistical physics of these associated systems is usually dominated by stretched brush-like regions. A sticker has to overcome a potential barrier both to penetrate the stretched structure or to escape a favorable region built by associated stickers. Our main result is that these barriers are crossed by tension fluctuations and that the corresponding processes are thus local with a friction independent of molecular weight. When the potential barriers are high, the (very stretched) equilibrium structures are not likely to develop on reasonable time scales. Stretched model systems may also be grown in situ from nuclei bearing initiating groups. These, irreversibly bound structures, are also briefly discussed.

description: This Introduction is by way of explanation and apology. First, let us treat of the explanation. In the following pages will be found what at first sight must appear an odd assortment of topics, an assortment not easily reconciled in terms of traditional pedagogical classifications. True, they have one thing in common; they all deal with some aspect of monopoly theory. But they also have a contextual unity and perhaps it will help to see the matters dealt with here in perspective, if we briefly outline the context in which they have arisen. Ultimately, the writer is concerned with the effects of monopoly upon economic growth, with determining whether monopoly represents the "hardening of capitalism's arteries” as suggested by Marxists and secular stagnationists, or whether monopoly gives capitalism new direction, "planning" and stability as argued by others, whether it tends to neutralize itself by the development of "countervailing power", or whether it is merely unimportant one way or the other, as often seems to be implied.
title: The Assessment of Different Cerebral Locations in the Study of Arousal and Attention Using a Closed Loop Tracking System

description: The present experiment assessed the importance of the temporal, parietal, and frontal lobes in a sustained attention task using a closed-loop arousal monitoring system for a tracking task. Thirty-six undergraduates from Old Dominion University in Norfolk, Virginia served as subjects. Subjects were randomly assigned to one of the lobe conditions and recordings were taken from sites over either their temporal, parietal or frontal lobes while they performed a compensatory tracking task. The monitoring system recorded the subject's beta, theta, and alpha wave production, an engagement index (derived from an algebraic function of the individual bandwidths) and the root mean square error on the tracking task. Each subject alternated between an automatic (computer-controlled) and manual (subject-controlled) tracking condition based upon their engagement index and the feedback modes, positive (designed to keep arousal levels moving in one direction) and negative (designed to keep arousal at a median level). It was hypothesized that the negative feedback mode would contain a significantly greater number of switches between control modes. This hypothesis was only supported by the frontal lobe group, E (1, 33) = 2.5, R < .10. Additionally, weak effects were found for tracking error E (1, 32) = 2.93, R < .10, with significantly greater tracking error under negative feedback. Trends in the individual bandwidths and engagement indexes are also discussed.

description: In hybrid digital-analog (HDA) systems, resource allocation has been utilized to achieve desired distortion performance. However, existing studies on this issue assume error-free digital transmission, which is not valid for fading channels. With time-varying channel fading, the exact channel state information is not available at the transmitter. Thus, random outage and resulting digital distortion cannot be ignored. Moreover, rate allocation should be considered in resource allocation, since it not only determines the amount of information for digital transmission and that for analog transmission, but also affects the outage probability. Based on above observations, in this paper, we attempt to perform joint rate and resource allocation strategies to optimize system distortion in HDA systems over fading channels. Consider a bandwidth expansion scenario where a memoryless Gaussian source is transmitted in an HDA system with the entropy-constrained scalar quantizer (ECSQ). Firstly, we formulate the joint allocation problem as an expected system distortion minimization problem where both analog and digital distortion are considered. Then, in the limit of low outage probability, we decompose the problem into two coupled sub-problems based on the block coordinate descent method, and propose an iterative gradient algorithm to approach the optimal solution. Furthermore, we extend our work to the multivariate Gaussian source scenario where a two-stage fast algorithm integrating rounding and greedy strategies is proposed to optimize the joint rate and resource allocation problem. Finally, simulation results demonstrate that the proposed algorithms can achieve up to 2.3dB gains in terms of signal-to-distortion ratio over existing schemes under the single Gaussian source scenario, and up to 3.5dB gains under the multivariate Gaussian source scenario.

description: Pseudogap phenomena of high-T_c cuprates are examined. In terms of AFM (antiferromagnetic) and dSC (d_{x^2-y^2}-wave superconducting) auxiliary fields introduced to integrate out the fermions, the effective action for 2D electron systems with AFM and dSC fluctuations is considered. By the self-consistent renormalization (SCR), the NMR relaxation rate T_1^{-1}, the spin correlation length ξ_σand the pairing correlation length ξ_d are calculated. From this calculation, a mechanism of the pseudogap formation emerges as the region of dominant d-wave short-range order (SRO) over AFM-SRO. When damping for the AFM fluctuation strongly depends on the dSC correlation length through the formation of precursor singlets around (π,0) and (0,π) points in the momentum space, the pseudogap appears in a region of the normal state characterized by decreasing 1/T_1T and increasing AFM correlation length with decrease in temperature. This reproduces a characteristic feature of the pseudogap phenomena in many underdoped cuprates. When the damping becomes insensitive to the dSC correlation length, the pseudogap region shrinks as in the overdoped cuprates.

description: Background and Purpose: Neuropsychiatric diseases are protean, affecting cognition, emotion and behaviour, including such diseases as reactions to traumatic stress (post-traumatic stress disorder), cerebrovascular disease and the neurodegenerative dementias. There has been much interest in understanding the neural basis of neuropsychiatric disease. A model that has been employed to investigate such disease has been the endophenotype, a restricted set of phenotypic or clinical features that may have a more specific structural and hence, genetic basis. An example of an endophenotype is frontal-executive neuropsychological function, localised to the neural substrate of dorsolateral prefrontal cortex frontostriatal circuit. Consequently, it is possible to explore the structural basis of an endophenotype by studying the components of neural circuits carrying such functions. Thus, frontostriatal circuits may be useful as a structural basis for endophenotypes related to frontal cognitive function. These circuits extensively mediate cognition, emotion and behaviour within humans. The caudate nucleus and putamen, comprising the human neostriatum, serve crucial roles within frontostriatal circuits. The caudate and putamen may thus serve as a potential, quantifiable component of the structural basis for endophenotypes. It was hypothesized that functional change may be reflected in structural changes in the neostriatum due to neuroplasticity. Thus functional activation or disconnection might impact upon the structure of the caudate or putamen. Other corticostriatal circuits in addition to frontostriatal circuits may thus be affected. These studies were designed to measure the volume of the neostriatum as a quantified neuroanatomical basis of the endophenotype of frontostriatal dysfunction within specific neuropsychiatric diseases.

description: Activation of quantum capacity is a surprising phenomenon according to which the quantum capacity of a certain channel may increase by combining it with another channel with zero quantum capacity. Superactivation describes an even more particular occurrence, in which both channels have zero quantum capacity, but their composition has a nonvanishing one. We investigate these effects for all single-mode phase-insensitive Gaussian channels, which include thermal attenuators and amplifiers, assisted by a two-mode positive-partial-transpose channel. Our result shows that activation phenomena are special but not uncommon. We can reveal superactivation in a broad range of thermal attenuator channels, even when the transmissivity is quite low. This means that we can transmit quantum information reliably through very noisy Gaussian channels having zero quantum capacity. We further show that no superactivation is possible for entanglement-breaking Gaussian channels in physically relevant circumstances by proving the non-activation property of the coherent information of bosonic entanglement-breaking channels with finite input energy.

Stephenson Percy Smith
Polynesian cociety
New Zealand

description: Stephenson Percy Smith, militia member, surveyor, ethnologist and ethnographer, and founder of the Polynesian Society and its Journal, had a major impact on the New Zealand of his day and on a world-wide community of Polynesianist scholars. Whereas a good deal of attention and critique has been given to his work on Māori and the settlement of New Zealand, the purpose of this thesis is to explore those of his writings substantially devoted to the island Pacific outside New Zealand. To that end, I assemble a single Text comprising all of those writings and proceed to read it in terms of itself but also in the light of the period in which it was written and of its intellectual context. My method, largely based on elements of the approach proposed by Roland Barthes in the early 1970s, involves first presenting a representation of that Text and then reading within it a historical figure, the author of its components, as a character in that Text. Before doing so, in a Prologue I set out the broad current understanding of the patterns of settlement of the Pacific and some of the origins of Smith’s racial framing. In order to establish context, the early chapters outline his life and career and the intellectual framework, European and New Zealand, within which he thought and wrote as well as the early history of the Hawaiki that would come to absorb him. The following chapters set out my representation and reading of the Smith Text and open up new perspectives on aspects of Smith’s concepts of race, of relations among those he conceives as races, and of the settlement of the Pacific. My reading reveals Smith’s concern to separate his Polynesians from the other ‘races’ with which they came into contact in order to preserve their integrity and purity. In particular, in exploring the relationship between possible origins and a certain destination, it throws light on the nature of his quest for Hawaiki, the Polynesian homeland, and, in particular, his drive to locate it beyond and prior to Polynesian contact with those other ‘races’. I conclude that, at least in one sense, the real origin of Smith’s Polynesians lies in the racial classification of Oceania that emerged in Europe in the eighteenth and nineteenth centuries and still flourished in the twentieth. I end with a vignette of Smith’s presence in contemporary Aotearoa New Zealand.

description: Quantum error correction and symmetry arise in many areas of physics, including many-body systems, metrology in the presence of noise, fault-tolerant computation, and holographic quantum gravity. Here we study the compatibility of these two important principles. If a logical quantum system is encoded into $n$ physical subsystems, we say that the code is covariant with respect to a symmetry group $G$ if a $G$ transformation on the logical system can be realized by performing transformations on the individual subsystems. For a $G$-covariant code with $G$ a continuous group, we derive a lower bound on the error correction infidelity following erasure of a subsystem. This bound approaches zero when the number of subsystems $n$ or the dimension $d$ of each subsystem is large. We exhibit codes achieving approximately the same scaling of infidelity with $n$ or $d$ as the lower bound. Leveraging tools from representation theory, we prove an approximate version of the Eastin-Knill theorem: If a code admits a universal set of transversal gates and corrects erasure with fixed accuracy, then, for each logical qubit, we need a number of physical qubits per subsystem that is inversely proportional to the error parameter. We construct codes covariant with respect to the full logical unitary group, achieving good accuracy for large $d$ (using random codes) or $n$ (using codes based on $W$-states). We systematically construct codes covariant with respect to general groups, obtaining natural generalizations of qubit codes to, for instance, oscillators and rotors. In the context of the AdS/CFT correspondence, our approach provides insight into how time evolution in the bulk corresponds to time evolution on the boundary without violating the Eastin-Knill theorem, and our five-rotor code can be stacked to form a covariant holographic code.

description: The recently emerged concept of all-dielectric nanophotonics based on optical Mie resonances in high-index dielectric nanoparticles has proven a promising pathway to boost light-matter interactions at the nanoscale. In this work, we discuss the opportunities enabled by the interaction of dielectric nanoresonators with 2D transition metal dichalcogenides (2D TMDCs), leading to weak and strong coupling regimes. We perform a comprehensive analysis of bright exciton photoluminescence (PL) enhancement from various 2D TMDCs, including WS2, MoS2, WSe2, and MoSe2 via their coupling to Mie resonances of a silicon nanoparticle. For each case, we find the system parameters corresponding to maximal PL enhancement taking into account excitation rate, Purcell factor, and radiation efficiency. We demonstrate numerically that all-dielectric Si nanoantennas can significantly enhance the PL intensity from 2D TMDC by a factor of hundred through precise optimization of the geometrical and material parameters. Our results may be useful for high-efficiency 2D TMDC-based optoelectronic, nanophotonic, and quantum optical devices.

description: In the third catalog of active galactic nuclei detected by the Fermi-LAT (3LAC) Clean Sample, there are 402 blazars candidates of uncertain type (BCU). Due to the limitations of astronomical observation or intrinsic properties, it is difficult to classify blazars using optical spectroscopy. The potential classification of BCUs using machine learning algorithms is essential. Based on the 3LAC Clean Sample, we collect 1420 Fermi blazars with 8 parameters of γ-ray photon spectral index, radio flux, flux density, curve significance, the integral photon flux in 100 to 300 MeV, 0.3 to 1 GeV, 10 to 100 GeV and variability index. Here, we apply 4 different supervised machine learning (SML) algorithms (\emph{Decision trees, Random forests, support vector machines and Mclust Gaussian finite mixture models}) to evaluate the classification of BCUs based on the direct observational properties. All the 4 methods can perform exceedingly well with a more accuracy and can effective forecast the classification of Fermi BCUs. The evaluating results show the results of these methods (SML) are valid and robust, where, about 1/4 sources are FSRQs and 3/4 are BL Lacs in 400 BCUs, which are consistent with some other recent results. Although a number of factors influence the accuracy of SML, the results are stable at a fixed ratio 1:3 between FSRQs and BL Lacs, which suggests that the SML can provides an effective method to evaluate the potential classification of BCUs. Among the 4 methods, Mclust Gaussian Mixture Modelling has the highest accuracy for our training sample (4/5, seed=123).

description: A generalized Noether's theorem and the operational determination of a physical geometry in quantum physics are used to motivate a quantum geometry consisting of relations between quantum states that are defined by a universal group. Making these relations dynamical implies the non local effect of the fundamental interactions on the wave function, as in the Aharonov-Bohm effect and its generalizations to non Abelian gauge fields and gravity. The usual space-time geometry is obtained as the classical limit of this quantum geometry using the quantum state space metric.

description: This thesis explores the institutional choices available to Timor-Leste to manage their natural resource wealth wisely and avoid the resource curse. Timor-Leste is a poor country and its challenge is to use its large per capita resource wealth to alleviate poverty and enable sustainable development. This research examines the Petroleum Fund Law, and other mechanisms to manage petroleum revenue that the Government of Timor-Leste has established. These mechanisms appear to be resilient, but remain untested. Based on field interviews in Timor-Leste, the study offers insights into the opinions of East Timorese and foreign advisers about how Timor-Leste´s petroleum revenue should be managed, and how a poor country can raise the living standards of its people.¶...

description: The extensive penetration of wind farms (WFs) presents challenges to the operation of distribution networks (DNs). Building a probability distribution of the aggregated wind power forecast error is of great value for decision making. However, as a result of recent government incentives, many WFs are being newly built with little historical data for training distribution models. Moreover, WFs with different stakeholders may refuse to submit the raw data to a data center for model training. To address these problems, a Gaussian mixture model (GMM) is applied to build the distribution of the aggregated wind power forecast error; then, the maximum a posteriori (MAP) estimation method is adopted to overcome the limited training data problem in GMM parameter estimation. Next, a distributed MAP estimation method is developed based on the average consensus filter algorithm to address the data privacy issue. The distribution control center is introduced into the distributed estimation process to acquire more precise estimation results and better adapt to the DN control architecture. The effectiveness of the proposed algorithm is empirically verified using historical data.

description: The Coalsack is a single dark nebula in Crux. It is probably the most conspicuous compact absorbing cloud in the southern Milky Way, visible to the naked eye against the background of diffuse light from the faint Milky Way stars. The only star visible in the body of the nebula is HD 110432, a Bo star of visual magnitude 5.4. The approximate centre of the nebula is at right ascension 12h 40m and southern declination 62° 40’, i.e. at galactic longitude 270° and latitude 0°. The main body of the nebula covers an area of approximately 23 square degrees in the sky and south of this an irregular tail extends towards the west losing itself in broken absorption patches in Carina. Though the Coalsack may seem a compact and isolated nebula, on photographic plates patches of widely varying obscuration become noticeable. On the Franklin Adams charts two main centres of absorption can be seen, one to the south-east of X Crucis and about one degree from it and the other similarly situated with respect to o^Crucis.

description: We propose a new quintessence scenario in the brane cosmology, assuming that a quintessence field $Q$ is confined in our 3-dimensional brane world. With a potential $V(Q)= μ^{α+4} Q^{-α}~(α\geq 2)$, we find that the density parameter of the scalar field decreases as $Ω_Q \sim a^{-4(α-2)/(α+2)}$ in the epoch of quadratic energy density dominance, if $α\leq 6$. This attractor solution is followed by the usual tracking quintessence scenario after a conventional Friedmann universe is recovered. With an equipartition of initial energy density, we find a natural and successful quintessence model for $α\gsim 4$.

description: The geometry and hydrodynamics of river reaches are key ecohydraulic descriptors. Statistics of water depth and velocity measurements are usually taken as proxies for habitat suitability in rivers. However, little is known about the sufficiency of data to produce effective and representative results. In this research, 19 reaches with differences in terms of discharge, river width, substrate, reach length, cross-section spacing and geomorphology are investigated. Measurements of flow depth and velocity were taken at multiple, equally spaced cross-sections along each reach. Data were sub-sampled using different methodologies and analysed each time. The sets of sub-sampled data were then compared with those calculated with the full data set from a reach. The focus was put towards the hydro-morphological index of diversity (HMID), a combination of the classical ecohydraulic variables flow depth and velocity. It represents the spatial variability of hydraulic habitats in a reach. The results point out that, with a well-defined sampling strategy, 100 measurement points lead to a good estimation of the HMID value in a reach, if more than eight measurement points are taken per cross-section. For geomorphologies with small complexity or when the analysis only includes the estimation of mean flow depth or mean flow velocity, this number can be decreased according to the results presented here. These findings help both, aquatic ecologists and engineers to estimate their data reliability for hydraulic field measurements in a river reach and are herein discussed taking into account the different studied morphologies.
White dwarf stars

Subjects: White dwarf stars Spectra

description: White dwarf stars were first discovered only fifty years ago, when the science of astrophysics was in its infancy. The original discovery appears to have been made by Russell (l). He had just found from his work on trigonometrical parallaxes that all intrinsically faint stars were of spectral type M and then learnt that 40 Eri B was both intrinsically faint and hot. Slightly later Adams (2) gave the spectrum of Sirius B as A or early F and van Maanen (3) described the spectrum, of van Maanen 2. These three stars were soon realised to be the prototype members of a class of stars of very small radius and high temperature which consequently became known as the white dwarfs. The small radius and high temperature of these stars implied a high density. The mass of Sirius B was known from its double star orbit with Sirius A and its parallax and apparent magnitude were also known. Adams’ spectra implied a temperature of 10,000°K. This temperature and the absolute magnitude implied a radius of about 19,000 km and this, combined with the mass of between 0.75 and 0.95 solar masses, gives a mean density of about 60,000 gm/cm3.

description: CO2 capture is a pressing global environmental issue that drives scientists to develop creative strategies for tackling this challenge. The concept in this contribution is to produce site specific nitrogen doping in microporous carbon fibers. It creates a carbon/carbon heterojunction by using poly(ionic liquid) (PIL) as soft activation agent that deposits nitrogen species exclusively on the skin of commercial microporous carbon fibers. Such carbon-based biphasic heterojunction amplifies the interaction between carbon fiber and CO2 molecule for unusually high CO2 uptake and resistive sensing.

description: Whereas some work has been done on triethylenetetramine (trien) complexes by relating magnetism (1,2,3,10) and spectra (4,5,6,7) to stereochemistry in the solid state, little is known about the precise configurations of the few compounds isolated, Even less structural information on complexes obtained only in solution has been provided by studies of complex formation by carious methods (1,2,11,21,23,26) and measurements of formation constants (20,21,22,24).

description: Flares are powerful events ignited by a sudden release of magnetic energy. With the aim of studying flares in the 125-Myr-old stars in the Pleiades observed simultaneously in optical and X-ray light, we obtained new XMM-Newton observations of this cluster during the observations of Kepler K2 Campaign 4. Our objective is to characterize the most powerful flares observed in both bands and to constrain the energy released in the optical and X-ray, the geometry of the loops, and their time evolution. We aim to compare our results to existing studies of flares occurring in the Sun and stars at different ages. We selected bright X-ray/optical flares occurred in 12 known members of the Pleiades from their K2 and XMM-Newton light curves. The sample includes ten K-M stars, one F9 star, and one G8 star. Flare average properties were obtained from integrated analysis of the light curves during the flares. The time evolution of the plasma in the magnetic loops is constrained with time-resolved X-ray spectral analysis. Most of the flares studied in this work emitted more energy in optical than in X-rays, as in most solar flares, even if the Pleiades flares output a larger fraction of their total energy in X-rays than typical solar flares do. Additionally, the energy budget in the two bands is weakly correlated. We also found comparable flare duration in optical and X-rays and observed that rapidly rotating stars (e.g., with rotation period shorter than 0.5 days) preferentially host short flares. We estimated the slope of the cooling path of the flares in the log(EM)-versus-log(T) plane. The values we obtained are affected by large uncertainties, but their nominal values suggest that the flares analyzed in this paper are mainly due to single loops with no sustained heating occurring during the cooling phase. We also observed and analyzed oscillations with a period of 500 s during one of the flares.

Subjects: subject: trade union
subject: Australia
subject: Labor unions
subject: Industrial policy

description: This thesis is concerned with the present relationship between trade unions and the state in Australia. It is argued that the relationship can be understood adequately only in terms of the relations existing in each of three areas - legal, administrative and party-political. The first involves the law affecting trade unions; the second, the unions' role in government administration, and the third, their role within a political party with which they are closely linked. An analysis of the relations established in each of theses areas is the main purpose of the thesis.

description: We report the results of extensive Dynamic Monte Carlo simulations of systems of self-assembled Equilibrium Polymers without rings in good solvent. Confirming recent theoretical predictions, the mean-chain length is found to scale as $\Lav = \Lstar (ϕ/\phistar)^α\propto ϕ^α\exp(δE)$ with exponents $α_d=δ_d=1/(1+γ) \approx 0.46$ and $α_s = [1+(γ-1)/(νd -1)]/2 \approx 0.60, δ_s=1/2$ in the dilute and semi-dilute limits respectively. The average size of the micelles, as measured by the end-to-end distance and the radius of gyration, follows a very similar crossover scaling to that of conventional quenched polymer chains. In the semi-dilute regime, the chain size distribution is found to be exponential, crossing over to a Schultz-Zimm type distribution in the dilute limit. The very large size of our simulations (which involve mean chain lengths up to 5000, even at high polymer densities) allows also an accurate determination of the self-avoiding walk susceptibility exponent $γ= 1.165 \pm 0.01$.

description: In the present study, an attempt was made to examine the mental forms related to brain hemisphericity of academic administrators. For the study, a sample of 1000 Academic Administrators working in various institutions of Tamil Nadu under the categories of High School, Higher Secondary School, Arts College, Science College, Teacher training Institutes, Colleges of Education, Polytechnics, Para-medical Colleges, Engineering Colleges, Medical Colleges. These were chosen, using stratified random sampling technique. The sample was administered through Index of Brain Hemisphericity consists of 50 statements which are designed by Venkataraman. D (1989) and Mental Forms Inventory constructed and Standardized by Venkataraman. D, Radhika.R (2011). Mean, Standard Deviation (S.D), t-test were used for the analysis and interpretation of the data. The findings of the study revealed that the Right Brain dominated Academic Administrators uses all the Mental Forms better than the Left and Integrated Brain dominants. Irrespective of Brain dominance Academic Administrators apply monarchic and Anarchic Mental Forms. The Mental Forms of Male are activated more than the Female. The Right Brain Female and Integrated Brain Male Academic Administrators are dominant in their Anarchic Mental Form. Left Brain oriented people do not show any gender difference glaringly. Right Brainers perform better Mental Forms than the Left and Integrated Brain dominants.

description: Basic mechanisms in gene expression are currently being investigated as targets in cancer therapeutics. One such fundamental process is the addition of the cap to pre-mRNA, which recruits mediators of mRNA processing and translation initiation. Maturation of the cap involves mRNA cap guanosine N-7 methylation, catalysed by RNMT (RNA guanine-7 methyltransferase). In a panel of breast cancer cell lines, we investigated whether all are equivalently dependent on RNMT for proliferation. When cellular RNMT activity was experimentally reduced by 50%, the proliferation rate of non-transformed mammary epithelial cells was unchanged, whereas a subset of breast cancer cell lines exhibited reduced proliferation and increased apoptosis. Most of the cell lines which exhibited enhanced dependency on RNMT harboured oncogenic mutations in PIK3CA, which encodes the p110α subunit of PI3 Kα. Conversely, all cell lines insensitive to RNMT depletion expressed wild-type PIK3CA. Expression of oncogenic PIK3CA mutants, which increase PI3 K p110α activity, was sufficient to increase dependency on RNMT. Conversely, inhibition of PI3 Kα reversed dependency on RNMT, suggesting that PI3 Kα signalling is required. Collectively, these findings provide evidence to support RNMT as a therapeutic target in breast cancer and suggest that therapies targeting RNMT would be most valuable in a PIK3CA mutant background.

description: We introduce a filter using a noise-free quantum buffer with large optical bandwidth that can both filter temporal-spectral modes, as well as inter-convert them and change their frequency. We show that such quantum buffers optimally filter out temporal-spectral noise; producing identical single-photons from many distinguishable noisy single-photon sources with the minimum required reduction in brightness. We then experimentally demonstrate a noise-free quantum buffer in a warm atomic system that is well matched to quantum dots and can outperform all intensity (incoherent) filtering schemes for increasing indistinguishability.
