description: This paper presents the projections on the anomalous neutral triple gauge couplings ($aNTGC$) via $pp \rightarrow ZZ$ production in the 2$\ell$2$ν$ final state at a 100 TeV proton-proton collider, \verb"FCC-hh". %100 TeV center of mass energy of The realistic \verb"FCC-hh" detector environments and its effects taken into account in the analysis. The study is carried out in the mode where one Z boson decays into a pair of same-flavor, opposite-sign leptons (electrons or muons) and the other one decays to the two neutrinos. The new bounds on the charge-parity (CP)-conserving couplings $C_{\widetilde{B}W} / Λ^{4}$ and CP-violating couplings $C_{WW} / Λ^{4}$, $C_{BW} / Λ^{4}$ and $C_{BB} / Λ^{4}$ achived at 95\% Confidence Level (C.L.) using the transverse momentum of the dilepton system ($p_{T}^{\ell \ell}$) are $[-\, 0.042, \,\, +\,0.042]$, $[-\,0.050, \,\, +\,0.050]$, $[-\,0.050, \,\, +\,0.050]$, and $[-\,0.048, \,\, +\,0.048]$ in units of TeV$^{-4}$, respectively.

African Afro-futurism: Allegories and Speculations
Creators: name: Steingo, Gavin
Publisher: name: Current Musicology
Year: 2017

description: In his seminal text, More Brilliant Than The Sun, Kodwo Eshun remarks upon a general tension within contemporary African-American music: a tension between the “Soulful” and the “Postsoul.” While acknowledging that the two terms are always simultaneously at play, Eshun ultimately comes down strongly in favor of the latter. I quote him at length: Like Brussels sprouts, humanism is good for you, nourishing, nurturing, soulwarming—and from Phyllis Wheatley to R. Kelly, present-day R&B is a perpetual fight for human status, a yearning for human rights, a struggle for inclusion within the human species. Allergic to cybersonic if not to sonic technology, mainstream American media—in its drive to banish alienation, and to recover a sense of the whole human being through belief systems that talk to the “real you”—compulsively deletes any intimation of an AfroDiasporic futurism, of a “webbed network” of computerhythms, machine mythology and conceptechnics which routes, reroutes and criss-crosses the Atlantic. This digital diaspora connecting the UK to the US, the Caribbean to Europe to Africa, is in Paul Gilroy’s definition a “rhizo-morphic, fractal structure,” a “transcultural, international formation.” [...] [By contrast] [t]he music of Alice Coltrane and Sun Ra, of Underground Resistance and George Russell, of Tricky and Martina, comes from the Outer Side. It alienates itself from the human; it arrives from the future. Alien Music is a synthetic recombinator, an applied art technology for amplifying the rates of becoming alien. Optimize the ratios of excentric-ity. Synthesize yourself. [...] From the outset, this Postsoul Era has been characterized by an extreme indifference towards the human. The human is a pointless and treacherous category. (Eshun 1998, 00[-006]-00[-005]) The debate that Eshun outlines—along with its rich lexicon of terms—has a formidable history, both preceding More Brilliant Than The Sun, and following that book’s publication. Taking a cue from Eshun, in this paper I examine a related—although not identical—tension within Afro-futurism, namely the tension between allegory and speculation.

description: Zooplankton is a vital component in the pelagic marine ecosystems, linking lower to higher trophic levels. A survey was conducted with R/V Dr. Fridtjof Nansen in Sri Lankan waters in summer 2018 to explore zooplankton dynamics in relation to abiotic and biotic variables. A distinct pattern in physical and biological properties characterized Sri Lankan waters into two ecosystems: (1) low production, high temperature, and low salinity in the east, and (2) high production, low temperature, and high salinity in the west. The highest mean abundance (1931 ind. m−3) and biomass (1.79 g dry wt. m−2) of zooplankton were significantly associated with cooler, high saline, and more productive waters in the North West and South West. In general, zooplankton were significantly more abundant in the west (1841 ind. m−3) than the east (707 ind. m−3). The most abundant copepod families were Paracalanidae (20.4%) and Tachidiidae (10.2%). The copepod Paracalanus parvus was the most dominant species. Our study reveals that temperature is a key driver explaining 67% of the variance in zooplankton biomass in this region. This study provides novel baseline results on spatial patterns of zooplankton abundance, biomass, and species composition from an understudied region of the north central Indian Ocean.
Recombinant Melody: Ten Things to Love About Willaert's Music
Creators: name: Schubert, Peter
Publisher: name: Current Musicology
Year: 2003

description: Willaert's music was much celebrated in its own time. Today, however, musicologists find little to praise outside of its sonorous richness and sen-sitivity to text. Its seamlessness and contrapuntal density seem to be re-spected but not loved. Michele Fromson writes that in spite of widespread and continued historical interest in his music, individual pieces have had a difficult time entering the musical mainstream. With the exception of a handful of especially tuneful chansons, madrigals and motets, few compositions have gained favor with modern performers or listeners, raising perplexing questions about the aesthetic quality of his music that still await satisfactory answers. In the following pages, I propose that the powerful expressive poten-tial of this music lies beneath the apparently seamless surface in the details of its contrapuntal complexity. Singling out a handful of "especially tune-ful pieces" is a dead end-most ofWillaert's music is melodically very uniform.

description: In contrast to many other domains, recommender systems in health services may benefit particularly from the incorporation of health domain knowledge, as it helps to provide meaningful and personalised recommendations catering to the individual's health needs. With recent advances in representation learning enabling the hierarchical embedding of health knowledge into the hyperbolic Poincare space, this work proposes a content-based recommender system for patient-doctor matchmaking in primary care based on patients' health profiles, enriched by pre-trained Poincare embeddings of the ICD-9 codes through transfer learning. The proposed model outperforms its conventional counterpart in terms of recommendation accuracy and has several important business implications for improving the patient-doctor relationship.

description: A scheme for implementing 2-qubit quantum controlled phase gate (QCPG) is proposed with two superconducting quantum interference devices (SQUIDs) in a cavity. The gate operations are realized within the two lower flux states of the SQUIDs by using a quantized cavity field and classical microwave pulses. Our scheme is achieved without any type of measurement, does not use the cavity mode as the data bus and only requires a very short resonant interaction of the SQUID-cavity system. As an application of the QCPG operation, we also propose a scheme for generating the cluster states of many SQUIDs.

Spectral line width decrease in the solar corona: resonant energy conversion from Alfv{é}n to acoustic waves

description: Observations reveal an increase with height of the line width of several coronal spectral lines probably caused by outwardly propagating Alfv{é}n waves. However, the spectral line width sometimes shows a sudden decrease at a height 0.1-0.2 R, where the ratio of sound to Alfven speeds may approach unity. Qualitative analysis shows that the resonant energy conversion from Alfven to acoustic waves near the region of the corona where the plasma $β$ approaches unity may explain the observed spectral line width reduction.

description: Metasurfaces consisting of electrically thin and densely packed planar arrays of subwavelength elements enable an unprecedented control of the impinging electromagnetic fields. Spatially modulated metasurfaces can efficiently tailor the spatial distribution of these fields with great flexibility. Similarly, time modulated metasurfaces can be successfully used to manipulate the frequency content and time variations of the impinging field. In this paper, we present time-modulated reflective metasurfaces that cause a frequency shift to the impinging radiation, thus realizing an artificial Doppler effect in a non-moving electrically thin structure. Starting from the theoretical analysis, we analytically derive the required time modulation of the surface admittance to achieve this effect, and present a realistic time-varying structure, based on a properly designed and dynamically tuned high-impedance surface. It is analytically and numerically demonstrated that the field emerging from the metasurface is up-,down-converted in frequency according to the modulation profile of the metasurface. The proposed metasurface concept, enabling a frequency modulation of the electromagnetic field on-the-fly, may find application in telecommunication, radar, and sensing scenarios.
Writing Under the Influence? Salieri and Schubert’s Early Opinion of Beethoven
Creators: name: Gibbs, Christopher H.
Publisher: name: Current Musicology
Year: 2003

description: In 1822, Schubert dedicated his Variations on a French Theme for Piano Four-Hands, Op. 10 (D624) to Beethoven. This dedication was his most public and extravagant proclamation of an abiding reverence for the older master that he held until his dying day. Indeed, if Ferdinand Schubert is to be believed, his younger brother’s last wish was to be buried near Beethoven, which is exactly what happened (Deutsch 1946:825). A lifelong devotion is implied in Schubert’s letters and plainly stated in the recollections of family and friends. The impress and challenge of Beethoven’s music on Schubert’s is also apparent from the start of his compositional career, and only intensified, I believe, as he matured and engaged with it ever more directly. Beyond purely compositional matters, Schubert modeled his professional career on Beethoven’s in crucial respects and benefited from his relations with many of the same performers, publishers, patrons, and critics who were involved with the older composer (Solomon 1979a; Gingerich 1996; Gibbs 2000). Contemporaries frequently made comparisons between their compositions; as we shall see, critics usually mentioned Beethoven when reviewing Schubert’s piano and chamber works.

description: The irreversible adsorption of polymers to a two-dimensional solid surface is studied. An operator formalism is introduced for chemisorption from a polydisperse solution of polymers which transforms the analysis of the adsorption process to a set of combinatorial problems on a two-dimensional lattice. The time evolution of the number of polymers attached and the surface area covered are calculated via a series expansion. The dependence of the final coverage on the parameters of the model (i.e. the parameters of the distribution of polymer lengths in the solution) is studied. Various methods for accelerating the convergence of the resulting infinite series are considered. To demonstrate the accuracy of the truncated series approach, the series expansion results are compared with the results of stochastic simulation.

description: The interest in two-dimensional and layered materials continues to expand, driven by the compelling properties of individual atomic layers that can be stacked and/or twisted into synthetic heterostructures. The plethora of electronic properties as well as the emergence of many different quasiparticles, including plasmons, polaritons, trions and excitons with large, tunable binding energies that all can be controlled and modulated through electrical means has given rise to many device applications. In addition, these materials exhibit both room-temperature spin and valley polarization, magnetism, superconductivity, piezoelectricity that are intricately dependent on the composition, crystal structure, stacking, twist angle, layer number and phases of these materials. Initial results on graphene exfoliated from single bulk crystals motivated the development of wide-area, high purity synthesis and heterojunctions with atomically clean interfaces. Now by opening this design space to new synthetic two-dimensional materials "beyond graphene", it is possible to explore uncharted opportunities in designing novel heterostructures for electrical tunable devices. To fully reveal the emerging functionalities and opportunities of these atomically thin materials in practical applications, this review highlights several representative and noteworthy research directions in the use of electrical means to tune these aforementioned physical and structural properties, with an emphasis on discussing major applications of beyond graphene 2D materials in tunable devices in the past few years and an outlook of what is to come in the next decade.

description: We analyze recent experiments on the dilute rare-earth compound LiHo_xY_(1-x)F_4 in the context of an effective Ising dipolar model. Using a Monte Carlo method we calculate the low-temperature behavior of the specific heat and linear susceptibility, and compare our results to measurements. In our model the susceptibility follows a Curie-Weiss law at high temperature, chi ~ 1/(T-T_cw), with a Curie-Weiss temperature that scales with dilution, T_cw ~ x, consistent with early experiments. We also find that the peak in the specific heat scales linearly with dilution, C_max(T) ~ x, in disagreement with recent experiments. Experimental studies do not reach a consensus on the functional form of these quantities, and in particular we do not see reported scalings of the form chi ~ T^-0.75 and chi ~ exp(-T/T_0). Furthermore we calculate the ground state magnetization as a function of dilution, and re-examine the phase diagram around the critical dilution x_c=0.24(3). We find that the spin glass susceptibility for the Ising model does not diverge below x_c, while recent experiments give strong evidence for a stable spin-glass phase in LiHo_0.167Y_0.833F_4.

description: The following discussion between Michael Veal and Whitney Slaten emerged amidst Veal’s presentations for Columbia’s Center for Jazz Studies in the 2015-2016 academic year. Drawing from the current research of Veal and Slaten, as well as the recent work in sound studies, this discussion explores the status of the human in black popular music studies. It begins by tracing the significance of how Veal situates his subjects locally, yet also in dialogue with important centers of black popular music throughout the Atlantic. In the wake of oppressive histories that have associated black musical expression to the permanent objectifications of slavery, the dis-course about Fred Moten’s important analysis of Aunt Hester’s scream as the supposed object’s resistance, and sound studies’ new turn to decenter social categories in favor of foregrounding sounds and sonic phenomena as objects, the second section asks the following question: how does post-humanism juxtapose with scholarship on black music? Considering the complexities associated with human and post-human approaches, the final section considers how blackness and labor figure in Slaten’s ethnographic research on professional live sound engineering in New York City.

description: We re-analyze the observed magnitude-redshift relation of type Ia supernovae (SNe Ia) and examine the possibility that the apparent acceleration of the cosmic expansion is not caused by dark energy but is instead a consequence of the large-scale inhomogeneities in the universe. We propose a method to phenomenologically describe the effects of the large-scale inhomogeneities without relying on the specific toy models of the inhomogeneous universe. This method clearly illustrates how the post-Friedmannian effects of inhomogeneities, i.e. the effects due to the deviation from a perfectly homogeneous and isotropic model, act as an effective cosmological constant in the magnitude-redshift relation of SNe Ia.

description: As it does with any continuing stimulus, the response to a prolonged tone or group of tones will eventually disappear from consciousness. How long this takes to happen will depend on the nature of the stimulus: in the case of a single tone, obviously on its loudness, but also on its structure, on whether this is simply sinusoidal, or compound. In any event, the tone must be repeated or a different tone sounded if a melodic formulation is to arise.

The Concept of Ausweichungin Music Theory, ca. 1770-1832
Creators: name: Saslaw, Janna K.
Publisher: name: Current Musicology
Year: 2003

description: In this essay I should like to address a misconception among some present-day writers who equate the late eighteenth-and early nineteenth-century German concept of Ausweichungwith the modern notion of modulation. One typical twentieth-century definition of modulation, from Arnold Schoenberg's the Structural Functions of Harmony, states that, "One should not speak of modulation unless a tonality has been abandoned definitely and for a considerable time, and another tonality has been established harmonically as well as thematically" (1968:19). Chromatic pitches intro-duced in a less definite manner are treated as embellishments to diatonic members of the prevailing key. Thus, the designation "V of V" indicates a harmony that, while not strictly diatonic, may be considered within the pitch constellation of a key.

O objetivo do presente estudo foi analisar e desmistificar informações veiculadas em mídia social e grupos de mensagens sobre pH, cloroquina e COVID-19.

Utilizou-se a metodologia de curadoria de conteúdo para analisar a qualidade, credibilidade e a veracidade ou falseabilidade de mensagens sobre COVID-19, pH e o uso de cloroquina.

As notícias analisadas apresentaram erros gramaticais, tipográficos e lógicos, mas tiveram alguns conteúdos parcialmente verdadeiros e outros pseudocientíficos que confundem os leitores. Baseando-se na fundamentação da biologia celular e molecular e da química, evidenciou-se uma complexidade nas possíveis relações entre pH, viabilidade viral e cloroquina.

Demonstrou-se, por meio da curadoria científica fundamentada na bioquímica, fisiologia e fisiopatologia, a falseabilidade da relação pH, SARS-Cov-2 e COVID-19, associada ou não à cloroquina, mensagem que deseduca e induz a uma falácia preventiva.

GSH : a new candidate neuropeptide in the CNS
Creators: name: Guo, Ningning
Publisher: name: University of British Columbia
Year: 2010

description: The physiological significance of glutathione (GSH) in the mammalian central nervous system is still uncertain, although some evidence has indicated that GSH may play an important role in the CNS. To address the question of whether GSH may be a candidate for a neuropeptide in the CNS, one step is to establish that GSH receptors are present. In the present study, biotinyl-GSH was synthesized and purified to detect the GSH receptor in the CNS. Histochemical experiments showed that GSH binding sites appeared on the white matter ( such as cingulum, dorsal hippocampal commissure, cerebral peduncle, fasciculus retrbflexus, mammillothalamic tract etc.) of the rat brain. It thus suggested that the GSH receptors might be on astrocytes or oligodendrocytes. Radioactive receptor assays were performed on cultured astrocytocytes using [³⁵S]GSH. Scatchard analysis revealed two binding sites of K₁ = 4.67±0.75 nM, Bmax₂ =70±9.2 fmoles / 6.4 x10⁵ cells (or Bmax₁=6.6 x10⁴molecules / cell), Kd₂=35.14±2.1 nM, Bmax₂=260±12.77 fmole / 6.4 x10⁵ cell (or Bmax₂ = 2.4 x10⁵ molecules / cell). The association and dissociation kinetics studies gave a K₊₁ of 0.003nM⁻¹min¹, and a K₋₁ of 0.0168 min⁻¹for site I. These rate constants gave a K₁ of 5.6 nM, consistent with that from Scatchard analysis. Colloidal gold technique and immunofluorescence double staining also showed the GSH binding sites on cultured astrocytes, and suggested that the binding sites might be GSH receptors. The present study is the first to report the presence of GSH receptors on astrocytes. Based on receptor binding assays and cytochemical experiments, this study not only depicts the biochemical characteristics of GSH receptors in the brain, but also shows the receptor at the cellular level. These results support the view that GSH might be a neuroactively signal substance in the CNS.

description: Flat bands near M points in the Brillouin zone are key features of honeycomb symmetry in artificial graphene (AG) where electrons may condense into novel correlated phases. Here we report the observation of van Hove singularity doublet of AG in GaAs quantum well transistors, which presents the evidence of flat bands in semiconductor AG. Two emerging peaks in photoluminescence spectra tuned by backgate voltages probe the singularity doublet of AG flat bands, and demonstrate their accessibility to the Fermi level. As the Fermi level crosses the doublet, the spectra display dramatic stability against electron density, indicating interplays between electron-electron interactions and honeycomb symmetry. Our results provide a new flexible platform to explore intriguing flat band physics.

A Suggestive Detail in Weber's Freischutz

description: But in Der Freischiitz I could never rejoice enough or without tears at the beginning of the third act. We are still full of horrible dark impressions from the gloomy Wolf's Glen-and all at once the curtain goes u~a calm, tranquil room, in which, through the green window drapes, a ray of sunshine brightly gleams, and about the sun, in which the presence of God is so palpable, and about the clouds, Agathe and the cello sing together! There is poetry, and scene-painting, and music-all together! (quoted in Gozenpud and Obram 1962:234). Thus waxed the twenty-three-year-old Alexander Serov to the nineteen-year-old Vladimir Stasov in a letter announcing his ambition to become a composer. Weber's Agathe is apt to strike even today's most sympathetic critics as "a little dull" (Warrack [1968] 1976:227), but nineteenth-century audiences loved and admired her as Weber intended. Intended? But yes.

description: We performed 2D and full 3D magnetohydrodynamic simulations of disk accretion to a rotating star with an aligned or misaligned dipole magnetic field. We investigated the rotational equilibrium state and derived from simulations the ratio between two main frequencies: the spin frequency of the star and the orbital frequency at the inner radius of the disk. In 3D simulations we observed different features related to the non-axisymmetry of the magnetospheric flow. These features may be responsible for high-frequency quasi-periodic oscillations (QPOs). Variability at much lower frequencies may be connected with restructuring of the magnetic flux threading the inner regions of the disk. Such variability is specifically strong at the propeller stage of evolution.

description: Using the Hamilton Echelle Spectrograph at Lick Observatory, we have obtained precise radial velocities (RVs) of a sample of 373 G- and K-giant stars over more than 12 years, leading to the discovery of several single and multiple planetary systems. The RVs of the long-period (~53 years) spectroscopic binary $ε$ Cyg (HIP 102488) are found to exhibit additional regular variations with a much shorter period (~291 days). We intend to improve the orbital solution of the $ε$ Cyg system and attempt to identify the cause of the nearly periodic shorter period variations, which might be due to an additional substellar companion. We used precise RV measurements of the K-giant star $ε$ Cyg from Lick Observatory, in combination with a large set of RVs collected more recently with the SONG telescope, as well as archival data sets. Our Keplerian model to the RVs characterizes the orbit of the spectroscopic binary to higher precision than achieved previously, resulting in a semi-major axis of $a = 15.8 \mathrm{AU}$, an eccentricity of $e = 0.93$, and a minimum mass of the secondary of $m \sin i = 0.265 M_\odot$. Additional short-period RV variations closely resemble the signal of a Jupiter-mass planet orbiting the evolved primary component with a period of $291 \mathrm{d}$, but the period and amplitude of the putative orbit change strongly over time. Furthermore, in our stability analysis of the system, no stable orbits could be found in a large region around the best fit. Both of these findings deem a planetary cause of the RV variations unlikely. Most of the investigated alternative scenarios, such as an hierarchical triple or stellar spots, also fail to explain the observed variability convincingly. Due to its very eccentric binary orbit, it seems possible, however, that $ε$ Cyg could be an extreme example of a heartbeat system.

description: In his near-classic The Recording Angel (2005), Evan Eisenberg points out that the actual legacy of automata in the twentieth century was machines like the phonograph or gramophone. Since so many automata were used as music boxes and existed for entertainment purposes and for refined contemplation in a European context, it is no surprise that they would evolve as they did in America. This emphasizes something more interest-ing than their pedigree: that in the years between Joice Heth, the black slave woman that P.T. Barnum passed for an automata, and (Karel Capek’s) R.U.R. (Rossum’s Universal Robots), the play that would introduce the term “robot” into the English language, ventriloquism and masquerade become increasingly properties of technology.

description: In this paper we construct massive supermultiplets out of appropriate set of massless ones in the same way as massive spin s particle could be constructed out of massless spin s,s-1,... ones leading to gauge invariant description of massive particle. Mainly we consider massive spin 3/2 supermultiplets in a flat d=4 Minkowski space both without central charge for N=1,2,3 as well as with central charge for N=2,4. Besides, we give two examples of massive N=1 supermultiplets with spin 3/2 and 2 in AdS_4 space.

Classifying Stars, Galaxies and AGN in CLAUDS+HSC-SSP Using Gradient Boosted Decision Trees

description: Classifying catalog objects as stars, galaxies, or AGN is a crucial part of any statistical study of galaxies. We describe our pipeline for binary (star/galaxy) and multiclass (star/galaxy/Type I AGN/Type II AGN) classification developed for the very deep CLAUDS+HSC-SSP $u^*grizy$ dataset. Our method uses the XGBoost implementation of Gradient Boosted Trees (GBT) to train ensembles of models which take photometry, colours, maximum surface brightnesses, and effective radii from all available bands as input, and output the probability that an object belongs to each of the classes under consideration. At $i_{AB}<25$ our binary star/galaxy model has AUC=0.9974 and at the threshold that maximizes our sample's weighted F1 score, selects a sample of galaxies with 99.7% purity and 99.8% completeness. We test the model's ability to generalize to objects fainter than those seen during training and find that extrapolation of ~1-2 magnitudes is reasonable for most applications provided that the galaxies in the training sample are representative of the range of redshifts and colours of the galaxies in the target sample. We also perform an exploratory analysis of the method's ability to identify AGN using a small x-ray selected sample and find that it holds promise for classifying type I AGN, although it performs less well for type II AGN. Our results demonstrate that GBTs provide a flexible, robust and efficient method for performing classification of catalog objects in large astronomical imaging surveys.

“Paths of Harmony” in the First Movement of Brahms’s Cello Sonata in E minor, Op. 38
Creators: name: Bernstein, David W.
Publisher: name: Current Musicology
Year: 2003

description: “The paths of harmony are tortuous,” wrote Arnold Schoenberg in his manuscript on the musical idea. They lead in all directions, approaching a starting point and leaving it again and again, leading astray, as they lend to a different point a momentary meaning that they soon take back again, producing climaxes that they know how to exceed, calling forth gigantic waves that ebb without coming to a standstill. Nevertheless, this seemingly random progress is based on a profound meaning that can be easily verified in music governed by tonality”. (1995:309-11) These words aptly describe Schoenberg’s dynamic model of tonality. Harmony creates states of rest and unrest-conditions which Schoenberg described as “centrifugal” and “centripetal” tendencies. He defined these relationships in terms of “distances” from the tonic, which he classified and graphically represented by the “chart of the regions” in Structural Functions of Harmony (1954:20,30,68-69). Schoenberg conceived of musical space in terms of two or more dimensions in which “musical ideas are presented as a unit.” Tonal function is multi-dimensional: pitches (i.e., scale-degrees), as well as chords and regions have either centripetal or centrifugal tendencies. They create states of rest or unrest, by either establishing the tonic region or undermining it. Schoenberg did not consider motivic processes as separate from harmony and large-scale tonal form, since a given motive implies certain tonal relationships.

description: Baisden, W. T., Pearson, L., & Rissman, C. W. F. 2021. A Source-To-Sink Contaminant Risk Framework to Support Water Quality Policy across Scales New Zealand Hydrological Society Conference, Wellington (30 November – 2 December 2021).

IntroductionIn the wrong place, or at excessive concentrations, nutrients (nitrogen and phosphorus) and sediment become contaminants. Along with pathogens, they require reduction to improve water quality. Our Land and Water National Science Challenge (OLW NSC) and Ministry for the Environment (MfE) have commissioned a research programme ‘Mapping Contaminants from Source to Sink’ to inform both national and local government policy and planning on the fate of freshwater contaminants, specifically nitrogen and phosphorus species, sediment, and microbes in our environment and will be used to support the implementation of the National Policy Statement for Freshwater Management (2020). The overall objective of this project is to produce a national landscape classification for water quality to support contaminant risk assessment for policy option development. The classification units will describe contaminant processes within parcels of land, surface water and shallow groundwater (hydrologically connected to streams and rivers). FrameworkThe water quality risk describes the intersection of three factors: 1. the pressure from land use and management contributing to contaminant generation, 2. the inherent susceptibility of the landscape to contaminant mobilisation, and3. the vulnerability of downstream receiving environments to contaminant loads.
Quantum Gaussian Channels with Additive Correlated Classical Noise

description: We provide a model to study memory effects in quantum Gaussian channels with additive classical noise over an arbitrary number of uses. The correlation among different uses is introduced by contiguous two-mode interactions. Numerical results for few modes are presented. They confirm the possibility to enhance the classical information rate with the aid of entangled inputs, and show a likely asymptotic behavior that should lead to the full capacity of the channel.
