description: The aim of this paper is sketch a theory of divisibility and factorisation in topological monoids, where finite products are replaced by convergent products. The algebraic case can then be viewed as the special case of discretely topologised topological monoids. In particular, we define the topological factorisation monoid, a generalisation of the factorisation monoid for algebraic monoids, and show that it is always topologically factorial: any element can be uniquely written as a convergent product of irreducible elements. We give some sufficient conditions for a topological monoid to be topologically factorial.

description: Applications of neural networks to data analyses in natural sciences are complicated by the fact that many inputs are subject to systematic uncertainties. To control the dependence of the neural network function to variations of the input space within these systematic uncertainties, several methods have been proposed. In this work, we propose a new approach of training the neural network by introducing penalties on the variation of the neural network output directly in the loss function. This is achieved at the cost of only a small number of additional hyperparameters. It can also be pursued by treating all systematic variations in the form of statistical weights. The proposed method is demonstrated with a simple example, based on pseudo-experiments, and by a more complex example from high-energy particle physics.

description: We theoretically study high-harmonic generation (HHG) from transition metal elements Mn and Mn$^+$, using full-dimensional, all-electron, first-principles simulations. The HHG spectra calculated with the time-dependent complete-active-space self-consistent-field (TD-CASSCF) and occupation-restricted multiple-active-space (TD-ORMAS) methods exhibit a prominent peak at $\sim 50$ eV, successfully reproducing resonant enhancement observed in previous experiments [R.A. Ganeev \textit{et al.}, Opt. Express \textbf{20}, 25239 (2012)]. Artificially freezing $3p$ orbitals in simulations results in its disappearance, which shows the essential role played by $3p$ electrons in the resonant harmonics (RH). Further transition-resolved analysis unambiguously identifies constructively interfering $3p$-$3d$ ($m=0,\pm 1$) giant resonance transitions as the origin of the RH, as also implied by its position in the spectra. Time-frequency analysis indicates that the recolliding electron combines with the parent ion to form the upper state of the transitions. In addition, this study shows that the TD-CASSCF and TD-ORMAS methods can be applied to open-shell atoms with many unpaired inner electrons.

description: Decoherence is a fundamental obstacle to the implementation of large-scale and low-noise quantum information processing devices. In this work, we suggest an approach for suppressing errors by employing pre-processing and post-processing unitary operations, which precede and follow the action of a decoherence channel. In contrast to quantum error correction and measurement-based methods, the suggested approach relies on specifically designed unitary operators for a particular state without the need in ancillary qubits or post-selection procedures. We consider the case of decoherence channels acting on a single qubit belonging to a many-qubit state. Pre-processing and post-processing operators can be either individual, that is acting on the qubit effected by the decoherence channel only, or collective, that is acting on the whole multi-qubit state. We give a classification of possible strategies for the protection scheme, analyze them, and derive expressions for the optimal unitary operators providing the maximal value of the fidelity regarding initial and final states. Specifically, we demonstrate the equivalence of the schemes where one of the unitary operations is individual while the other is collective. We then consider the realization of our approach for the basic decoherence models, which include single-qubit depolarizing, dephasing, and amplitude damping channels. We also demonstrate that the decoherence robustness of multi-qubit states for these decoherence models is determined by the entropy of the reduced state of the qubit undergoing the decoherence channel.

description: We prove that time-periodic solutions arise via Hopf bifurcation in a finite closed system of coagulation-fragmentation equations. The system we treat is a variant of the Becker-Doering equations, in which clusters grow or shrink by addition or deletion of monomers. To this is added a linear atomization reaction for clusters of maximum size. The structure of the system is motivated by models of gas evolution oscillators in physical chemistry, which exhibit temporal oscillations under certain input/output conditions.

description: The Landau level laser has been proposed a long time ago as a unique source of monochromatic radiation, widely tunable in the THz and infrared spectral ranges using an externally applied magnetic field. In spite of decades of efforts, this appealing concept never resulted in the design of a reliable device. This is due to efficient Auger scattering of Landau-quantized electrons, which is an intrinsic non-radiative recombination channel that eventually gains over cyclotron emission in all materials studied so far: in conventional semiconductors with parabolic bands, but also in graphene with massless electrons. The Auger processes are favored in these systems by Landau levels (or their subsets) equally spaced in energy. Here we show that this scheme does not apply to massless Kane electrons in gapless HgCdTe alloy, in which undesirable Auger scattering is strongly suppressed and the sizeable cyclotron emission observed, for the first time in the case of massless particles. The gapless HgCdTe thus appears as a material of choice for future technology of Landau level lasers.

Brain mechanisms of affect and learning

Subjects: subject: Psychology

subject: FOS: Clinical medicine

description: Learning and affect are considered empirically separable, but these constructs bidirectionally interact.  While it has been demonstrated that dopamine supports the informational component of reward learning, the term "reward" inherently infers that a subjective positive experience is necessary to drive appetitive behavior.
      In this dissertation, I will first review the ways in which dopamine operates on the levels of physiology and systems neuroscience to support learning from both positive and negative outcomes, as well as how this framework may be employed to study mechanism and disease. I will then review the ways in which learning may interact with or be supported by other brain systems, starting with affective networks and extending into systems that support memory and other types of broader decision making processes. Finally, my introduction will discuss a disease model, schizophrenia, and how applying questions pertaining to learning theory may contribute to understanding symptom-related mechanisms.
      The first study (Chapter 2) will address the way in which affective and sensory mechanisms may alter pain-related decisions. I will demonstrate that subjects will choose to experience a stimulus that incorporates a moment of pain relief over a shorter stimulus that encompasses less net pain, and will suggest that the positive prediction error associated with the pain relief may modulate explicit memory in such a way that impacts later decision making.
      In the second study (Chapter 3), I will examine reward learning in patients with schizophrenia, and demonstrate selective learning deficits from gains as opposed to losses, as well as relationships in performance to affective and motivational symptoms. The third study (Chapter 4) will extend this disease model to a novel cohort of subjects who perform the same reward learning task while undergoing functional MRI. The data from this chapter will reveal deficits in the patient group during choice in orbitofrontal cortex, as well as an abnormal pattern of learning signal responses during feedback versus outcome, particularly in orbitofrontal cortex, a finding that correlates with affective symptoms in medial PFC.
      Taken together, these data demonstrate that learning is comprised of both informational and affective processes that incorporate input from dopaminergic midbrain neurons and its targets, as well as integration from other affective, mnemonic, and sensory regions to support healthy learning, emotion, and adaptive behavior.

Holotype: MNHN S2 PYU 402, tunic, body on microscope slides S2643–644, Mozambique: Ibo Island, coll. C. Monniot, 1995.
 Description
The single specimen is spherical, 12 mm in diameter. The tunic is red, hard and thick. Its surface is irregularly corrugated, with bumps that are more defined around the siphons. The siphons are sessile. The thin body wall reveals the internal organs in transparency. The musculature comprises strong sphincters at the siphons and radiating ribbons, strong and regularly spaced at their origin and dividing down the sides of the body into thinner fibres that reach the medioventral line.
There are a dozen long oral tentacles with only short first order ramifications, intercalated with some much shorter tentacles with lateral buttons, and between them one or two orders of very small tentacles that are not ramified. The prepharyngeal band has two equal rims. It curves in a dorsal V and extends as a groove at the start of the dorsal lamina.
The dorsal tubercle, flat and discoid, opens anteriorly in a C (Fig. 28A).
The branchial sac has six high, wide folds on each side, each with 13–15 longitudinal vessels; the folds are separated from each other by two vessels. The folds are not well delimited. There are parastigmatic vessels. The dorsal lamina is made of long denselypacked languets.
The digestive tract makes a wide loop on most of the left side of the body (Fig. 28A). The hepatic gland is divided into several lobes along half of the ascending limb of the gut (Fig. 28A). The anus is gaping with a smooth rim that is not rolled.
There is a voluminous gonad on each side (Fig. 28B,C), the left one totally included in the gut loop (Fig. 28A). The right gonad is ventral, parallel to the endostyle. In each gonad, the ovary is made of regularly spaced lobes perpendicular to a straight axial part. On the top of each ovarian lobe a few testis vesicles make a cap (Fig. 28D). Each testicular element produces a duct joining a common sperm duct that runs along the surface of the ovarian axis. Male and female papillae are united.
The internal layer of the body wall is covered with numerous, more-or-less elongated endocarps, as well as with the gonads and gut (Fig. 28A).
The cloacal siphon’s internal opening is surrounded by a network of large ramified tentacles.
This new species differs from congenerics mainly by the large number of its endocarps and the very large and branched cloacal tentacles.
 Etymology
The species name refers to the geographical origin of the species.

description: This project proceeds from a narrow question: What, if anything, is a brain wave? Beguiling in its simplicity, this question prompts a cultural-historical investigation that spans over 150 years of science, technology, and society. Proposed in 1869, the original theory of brain waves cites etheric undulations to explain reports of apparent thought transference. Though most modern thinkers no longer believe in outright telepathy, I argue that dreams of thought transmission and other mental miracles subtly persist—not in obscure and occult circles, but at the forefront of technoscience.
      A hybrid of science and fiction, brain waves represent an ideal subject through which to explore the ways in which technical language shrouds spiritual dreams. Today, the phrase “brain waves” often function as shorthand for electrical changes in the brain, particularly in the context of technologies that purport to “read” some aspect of mental function, or to transmit neural data to a digital device. While such technologies appear uniquely modern, the history of brain waves reveals that they are merely the millennial incarnation of a much older hope—a hope for transmission and transcendence via the brain’s emanations.

Using spatial partitioning to reduce the bit error rate of diffusion-based molecular communications

description: This work builds on our earlier work on designing demodulators for diffusion-based molecular communications using a Markovian approach. The demodulation filters take the form of an ordinary differential equation (ODE) which computes the log-posteriori probability of observing a transmission symbol given the continuous history of receptor activities. A limitation of our earlier work is that the receiver is assumed to be a small cubic volume called a voxel. In this work, we extend the maximum a-posteriori demodulation to the case where the receiver may consist of multiple voxels and derive the ODE for log-posteriori probability calculation. This extension allows us to study receiver behaviour of different volumes and shapes. In particular, it also allows us to consider spatially partitioned receivers where the chemicals in the receiver are not allowed to mix. The key result of this paper is that spatial partitioning can be used to reduce bit-error rate in diffusion-based molecular communications.

description: Point feature selection aims at preserving global patterns of point cluster during map scaling. This is an important technique for clear presentation of points in multi-scale maps. However, existing methods tend to include single point features ignoring the spatial interactions between two types of points. For example, based on the Input Sharing mechanism in agglomeration economics, different types of facilities are usually co-located together to reinforce their functions in business competition. In this respect, generalization of a point feature should consider not only its own importance but also the reinforcing effects from other features. In this paper, an improved method is proposed by including the spatial contextual information. Experiments suggest that our method can preserve service patterns after generalization.

Distributions for different ranges of electron number are obtained in both symmetric and asymmetric potentials. The even/odd effect is pronounced for small symmetric dots but vanishes for large asymmetric ones, suggesting substantially stronger interaction effects than expected. The fraction of high-spin ground states is remarkably large.

description: Modern design communication fails to engage our tactile senses. In an age where the majority of messages are delivered digitally, this preferences our eyes and ears over the remaining senses and as a result, the touch or ‘tactile’ senses are being neglected. Imagine a child born into a digital world where they no longer get to touch the ‘real thing’. What happens to us when there is no longer a stored memory of textures? As a child, touching rough, smooth and a variety of different textures to discover what they ‘feel’ like is essential to developing an understanding of our world (Elgin 1997). Since the introduction of digital technology into our everyday lives however, the computer mouse, keyboards, trackpads, and touch screens are fast becoming the main textures we spend our day touching (Bergmann 2010). If we as graphic communicators ignore the tactile, we are missing out on delivering some valuable sensory information by neglecting touch in the communication equation. My studio research seeks to discover if engaging with touch and re-imagining the digital aesthetic as analogue ‘one-offs’ are effective ways for graphic designers to reinvigorate their creativity and enrich visual communication within the digital landscape. The desktop computer has ultimately been responsible for a wealth of changes to the graphic design landscape. Typography as an art form, is also undergoing reinvention as a result of the digital revolution, but type usage is still embedded within graphic design as a primary tool of communication. Typography as an art, if it is to be preserved, must have a clear and renewed focus as a visual art form.

description: Collaborative filtering (CF) is a core technique for recommender systems. Traditional CF approaches exploit user-item relations (e.g., clicks, likes, and views) only and hence they suffer from the data sparsity issue. Items are usually associated with unstructured text such as article abstracts and product reviews. We develop a Personalized Neural Embedding (PNE) framework to exploit both interactions and words seamlessly. We learn such embeddings of users, items, and words jointly, and predict user preferences on items based on these learned representations. PNE estimates the probability that a user will like an item by two terms---behavior factors and semantic factors. On two real-world datasets, PNE shows better performance than four state-of-the-art baselines in terms of three metrics. We also show that PNE learns meaningful word embeddings by visualization.

description: We elaborate the trigonometric version of intertwining vectors and factorized L-operators. The starting point is the corresponding elliptic construction with Belavin's R-matrix. The naive trigonometric limit is singular and a careful analysis is needed. It is shown that the construction admits several different trigonometric degenerations. As a by-product, a quantum Lax operator for the trigonometric Ruijsenaars model intertwined by a non-dynamical R-matrix is obtained. The latter differs from the standard trigonometric R-matrix of $A_n$ type. A connection with the dynamical R-matrix approach is discussed.

description: With a computer-aided approach based on the connection with equitable partitions, we establish the uniqueness of the orthogonal array OA$(1536,13,2,7)$, constructed in [D.G.Fon-Der-Flaass. Perfect $2$-Colorings of a Hypercube, Sib. Math. J. 48 (2007), 740-745] as an equitable partition of the $13$-cube with quotient matrix $[[0,13],[3,10]]$. By shortening the OA$(1536,13,2,7)$, we obtain $3$ inequivalent orthogonal arrays OA$(768,12,2,6)$, which is a complete classification for these parameters too. After our computing, the first parameters of unclassified binary orthogonal arrays OA$(N,n,2,t)$ attending the Friedman bound $N\ge 2^n(1-n/2(t+1))$ are OA$(2048,14,2,7)$. Such array can be obtained by puncturing any binary $1$-perfect code of length $15$. We construct orthogonal arrays with these and similar parameters OA$(N=2^{n-m+1},n=2^m-2,2,t=2^{m-1}-1)$, $m\ge 4$, that are not punctured $1$-perfect codes. Additionally, we prove that any orthogonal array OA$(N,n,2,t)$ with even $t$ attending the bound $N \ge 2^n(1-(n+1)/2(t+2))$ induces an equitable $3$-partition of the $n$-cube.

The authors also indicate how, using singular points and singular submanifolds of a lightlike hypersurface $V \subset (M, c)$, to construct an invariant normalization of $V$ intrinsically connected with $V$.

With their large dielectric constants, stable and low-formation-energy interfaces, large valence offsets, and reasonable (though not optimal) conduction offsets (electron injection barriers), zirconia and hafnia appear to have a considerable potential as gate oxides for Si electronics.

description: Recent developments in enhanced sampling methods showed that it is possible to reconstruct ligand unbinding pathways with spatial and temporal resolution inaccessible to experiments. Ideally, such techniques should provide an atomistic definition of possibly many reaction pathways, because crude estimates may lead either to overestimating energy barriers, or inability to sample hidden energy barriers that are not captured by reaction pathway estimates. Here we provide an implementation of a new method [J. Rydzewski \& O. Valsson, J. Chem. Phys. {\bf 150}, 221101 (2019)] dedicated entirely to sampling the reaction pathways of the ligand-protein dissociation process. The program, called \texttt{maze}, is implemented as an official module for PLUMED 2, an open source library for enhanced sampling in molecular systems, and comprises algorithms to find multiple heterogeneous reaction pathways of ligand unbinding from proteins during atomistic simulations. The \texttt{maze} module requires only a crystallographic structure to start a simulation, and does not depend on many \textit{ad hoc} parameters. The program is based on enhanced sampling and non-convex optimization methods. To present its applicability and flexibility, we provide several examples of ligand unbinding pathways along transient protein tunnels reconstructed by \texttt{maze} in a model ligand-protein system, and discuss the details of the implementation.

description: We consider subtorus actions on divisorial toric varieties. Here divisoriality means that the variety has many Cartier divisors like quasiprojective and smooth ones. We characterize when a subtorus action on such a toric variety admits a categorical quotient in the category of divisorial varieties. Our result generalizes previous statements for the quasiprojective case. An important tool for the proof is a universal reduction of an arbitrary toric variety to a divisorial one. This is done in terms of support maps, a notion generalizing support functions on a polytopal fan. A further essential step is the decomposition of a given subtorus invariant regular map to a divisorial variety into an invariant toric part followed by a non-toric part.

description: Since the collapse of the Soviet Union in the early 1990s, there has been remarkable enthusiasm for theorising how transitional processes have unfolded in post-socialist cities. In seeking to extend literature that uses the post- socialist condition as a tool for theory building, we draw attention to the ongoing processes of institutional change in post-socialist cities. In doing so, we reject a ‘top-down’ perspective and examine how these institutional transitions are shaped through processes of ‘domestication’, negotiation and contestation between different interest groups in the city. We develop our argument, by drawing attention to the local political debates surrounding the propiska in Bishkek, Kyrgyzstan. The propiska developed throughout the Soviet Union to control internal migration and is still used today in a less restrictive form. By discussing our case study, we hope to foster attention towards the ongoing contested processes of institutional transition in post- socialist cities.

Dynamic nuclear spin polarization induced by Edelstein effect at Bi(111) surfaces

description: Nuclear spin polarization induced by hyperfine interaction and the Edelstein effect due to strong spin-orbit interaction is investigated by quantum transport in Bi(111) thin film samples. The Bi(111) films are deposited on mica by van der Waals epitaxial growth. The Bi(111) films show micrometer-sized triangular islands with 0.39 nm step height, corresponding to the Bi(111) bilayer height. At low temperatures a high current density is applied to generate a non-equilibrium carrier spin polarization by the Edelstein effect at the Bi(111) surface, which then induces dynamic nuclear polarization by hyperfine interaction. Comparative quantum magnetotransport antilocalization measurements indicate a suppression of antilocalization by the in-plane Overhauser field from the nuclear polarization and allow a quantification of the Overhauser field. Hence nuclear polarization was both achieved and quantified by a purely electronic transport-based approach.

title: An Analytical Index for Evaluating Low-Pressure Hollow-Fibre Membrane Systems

Subjects: subject: Wastewater treatment
subject: Membrane filtration technology

description: Water and wastewater treatment through the use of membrane filtration technology is one of the processes utilised currently to meet the growing demand for water. While new technologies can harness water from various non-traditional sources such as oceans, there remains the possibility of making drinking water more expensive through the use of costly treatment equipment. To prevent this and ensuing catastrophes around the world, the water industry needs a strategy that keeps the price of water and price of products aiding in the treatment of water controlled into the future. The overall aim of this study is to develop an analytical index that could be used by the water industry to measure, monitor, and control the price of water. A structured method to evaluate membrane manufacturing costs against the lifetime performance of membranes was developed. The method was then extended and a costing model for the application of membrane in water and wastewater treatment plants was established. Thereafter, a software application was developed to aid in the implementation of the analytical index. The results indicate that, with a measurable index in place, the evaluation of technologies with respect to the cost of water production can be effectively carried out.
Expansion of an interacting Fermi gas

description: We study the expansion of a dilute ultracold sample of fermions initially trapped in a anisotropic harmonic trap. The expansion of the cloud provides valuable information about the state of the system and the role of interactions. In particular the time evolution of the deformation of the expanding cloud behaves quite differently depending on whether the system is in the normal or in the superfluid phase. For the superfluid phase, we predict an inversion of the deformation of the sample, similarly to what happens with Bose-Einstein condensates. Viceversa, in the normal phase, the inversion of the aspect ratio is never achieved, if the mean field interaction is attractive and collisions are negligible.

description: ZYGOPALME GEN. NOV.    Diagnosis
Colony encrusting, uni- to biserial. Autozooids with smooth gymnocystal frontal shield lacking foramina. Zooidal orifices with minute proximolateral indentations and a median suboral suture; no excavations in adjacent gymnocyst. No spines or avicularia. Maternal orifice slightly larger than autozooidal orifice; brooding internal, with a distal ovicell-like kenozooid with a large central perforation; two tiny accessory pores frontally. Ancestrula with membranous frontal wall only, no spines. Interzooidal communications via uniporous mural septula.
 Type species: Eurystomella crystallina Gordon (1984).
 Etymology
 From zygas (Greek) pair, and palme (f. Greek) shield, alluding to the linear colonial morphology in which zooids may be biserial.
 Remarks
 Cladistic analysis has tended to highlight the differences between Zygopalme crystallina and other encrusting eurystomellids. Two characters are unique for this species and considered synapomorphies for this monotypic genus. These are the scarcely differentiated proximal corners of the orificial anter, and three kenozooidal foramina (one central, plus two small frontal pores) (see also Cladistic Analysis, below). Autapomorphic characters include the linear colony form and absence of gymnocystal foramina but retention of the median suboral suture. At present the genus is known only from a single station on the southern half of the Kermadec Ridge (33°S), on scleractinian coral at 350 m depth. It was fully described and illustrated by SEM by Gordon (1984).

Brand New Worlds: Disney's Theatre Assemblages

description: The significance of brands within our media-intensive culture can hardly be overstated. Having emerged in the mid-20th century as platforms for the distribution of commodities, brands have since become, as scholar Celia Lury argues, “the logos of the global economy.” Brand interfaces not only differentiate mass production, but produce cultural assemblages that rewrite social and political relations. This dissertation concerns itself with the meaning of theatrical production within brand performance, with a specific focus on the Walt Disney Company. Although there are many corporate producers in commercial theatre today — Warner Brothers, MGM, Universal, and Cirque du Soleil, to name a few — Disney has the distinction of being the first to make live theatre a cornerstone of its brand relationships. Disney has also had, in branding terms, the most depth, breadth and consistency of any global entertainment brand. Using the concept of assemblage as an applied framework, I consider how Disney’s brand theatre functions as a form of communicative/affective capitalism, as an interface for consumer interactivity and exchange. Following Deleuze and Guattari, DeLanda and Lury, I argue that Disney’s theatre assemblages are heterogeneous, contingent, emergent and most of all generative. At the heart of this project is the question of how Disney’s theatre assemblages cohere – the question of identifiable, intensive continuities. What kinds of historical contingencies are replicated in Disney’s texts and territories? How does the company code cultural flows? In what ways are Disney’s theatre assemblages networked to social formations like childhood, gender, race, sexuality, and nation? What kinds of consumer interactions and socio-technical conditions are most important to the ongoing process of developing brand relations? Although Disney’s multi-modal theatre assemblages are a function of neoliberal logic and labor norms, and sustain dominant modes of production, they are also highly mutable, often supporting contested claims of intelligibility and citizenship. The company produces a vast range of theatre experiences. This dissertation focuses on character encounters, children’s theatre, Broadway musicals, a re-creation of Buffalo Bill’s Wild West and animal/safari performance. The chapters are composed as a nested set of assemblages, starting with theatre for Disney’s most important demographic: children. I then move into larger social fields/assemblages, considering theatre that addresses the nation, theatre that reframes transnational/global space, and finally, animal/ecological theatre. Taken together, the chapters present an argument for the significance of brand theatre as a localized, expressive, collaborative and extremely flexible site of cultural affiliation, agency and assembly.
