description: Ultrafast pump-probe experiments open the possibility to track fundamental material behaviour like changes in its electronic configuration in real time. To date, most of these experiments are performed using an electron or a high-energy photon beam, which is synchronized to an infrared laser pulse. Entirely new opportunities can be explored if not only a single, but multiple synchronized, ultra-short, high-energy beams are used. However, this requires advanced radiation sources that are capable of producing dual-energy electron beams, for example. Here, we demonstrate simultaneous generation of twin-electron beams from a single compact laser wakefield accelerator. The energy of each beam can be individually adjusted over a wide range and our analysis shows that the bunch lengths and their delay inherently amount to femtoseconds. Our proof-of-concept results demonstrate an elegant way to perform multi-beam experiments in future on a laboratory scale.

description: Newell (1980; 1990) proposed that cognitive theories be developed in an effort to satisfy multiple criteria and to avoid theoretical myopia. He provided two overlapping lists of 13 criteria that the human cognitive architecture would have to satisfy in order to be functional. We have distilled these into 12 criteria: flexible behavior, real-time performance, adaptive behavior, vast knowledge base, dynamic behavior, knowledge integration, natural language, learning, development, evolution, and brain realization. There would be greater theoretical progress if we evaluated theories by a broad set of criteria such as these and attended to the weaknesses such evaluations revealed. To illustrate how theories can be evaluated we apply these criteria to both classical connectionism (McClelland & Rumelhart 1986; Rumelhart & McClelland 1986b) and the ACT-R theory (Anderson & Lebiere 1998). The strengths of classical connectionism on this test derive from its intense effort in addressing empirical phenomena in such domains as language and cognitive development. Its weaknesses derive from its failure to acknowledge a symbolic level to thought. In contrast, ACT-R includes both symbolic and subsymbolic components. The strengths of the ACT-R theory derive from its tight integration of the symbolic component with the subsymbolic component. Its weaknesses largely derive from its failure, as yet, to adequately engage in intensive analyses of issues related to certain criteria on Newell's list.

description: We present multidimensional non-LTE radiative transfer models of hydrogen and helium line profiles formed in the accretion flows and the outflows near the star-disk interaction regions of classical T Tauri stars (CTTSs). The statistical equilibrium calculations, performed under the assumption of the Sobolev approximation using the radiative transfer code TORUS, has been improved to include He I and He II energy levels. This allows us to probe the physical conditions of the inner wind of CTTSs by simultaneously modelling the robust wind diagnostic line He I (10830) and the accretion diagnostic lines such as Pa-beta, Br-gamma and He I (5876). The code has been tested in 1 and 2-D problems, and we have shown that the results are in agreement with established codes. We apply the model to the complex flow geometries of CTTSs. Example model profiles are computed using the combinations of (1) magnetospheric accretion and disc wind, and (2) magnetospheric accretion and the stellar wind. In both cases, the model produces line profiles which are qualitatively similar to those found in observations. Our models are consistent with the scenario in which the narrow blueshifted absorption component of He I (10830) seen in observations is caused by a disc wind, and the wider blueshifted absorption component (the P-Cygni profile) is caused by a bipolar stellar wind. However, we do not have a strong constraint on the relative importance of the wind and the magnetosphere for the `emission' component. Our preliminary calculations suggest that the temperatures of the disc wind, stellar wind and the magnetosphere cannot be much higher than ~10,000 K, on the basis of the strengths of hydrogen lines. With these low temperatures, we find that the photoionzation by high energy photons (e.g. X-rays) is necessary to produce He I (10830) in emission and to produce the blueshifted absorption components.

description: The transition from single-cell to multicellular behavior is important in early development but rarely studied. The starvation-induced aggregation of the social amoeba Dictyostelium discoideum into a multicellular slug is known to result from single-cell chemotaxis towards emitted pulses of cyclic adenosine monophosphate (cAMP). However, how exactly do transient short-range chemical gradients lead to coherent collective movement at a macroscopic scale? Here, we use a multiscale model verified by quantitative microscopy to describe wide-ranging behaviors from chemotaxis and excitability of individual cells to aggregation of thousands of cells. To better understand the mechanism of long-range cell-cell communication and hence aggregation, we analyze cell-cell correlations, showing evidence for self-organization at the onset of aggregation (as opposed to following a leader cell). Surprisingly, cell collectives, despite their finite size, show features of criticality known from phase transitions in physical systems. Application of external cAMP perturbations in our simulations near the sensitive critical point allows steering cells into early aggregation and towards certain locations but not once an aggregation center has been chosen.

EFFECT OF FINENESS OF SUGARCANE BAGASSE ASH ON MECHANICAL PROPERTY OF CONCRETE

Year: 2019
Subjects: Cement, Sugarcane Bagasse Ash, Sieve Size, Strength of Concrete

description: Sugarcane bagasse ash is a byproduct of the sugar factories found after burning sugarcane bagasse. The disposal of this material is already causing environmental problems around the sugar factories. In addition to that due to the boost of the construction activity in the country, a huge shortage is created in most of the construction materials especially cement, resulting in steady increase of price. Therefore the objective of this study is to examine the fineness of bagasse ash in concrete production using different percentage. Initially, bagasse ash samples were collected from Metehara sugar factory and its chemical properties were investigated. The range of application of using bagasse ash as a partial replacement for Ordinary Portland cement for concrete production has been experimentally investigated from the perspective of strength, fineness and workability of concrete. Strength of concrete was investigated at 7th and 28th day of the concrete. Systematic experiments were conducted for Bagasse ash retain at 45μm,75μm,150μm sieve size with replacement ratios of 0%, 5%, 10%,15% and 20% of ordinary Portland cement were prepared for 25MPa at constant water to cement ratio The properties of these mixes have then been assessed both at the fresh and hardened state. In the experimental result, a strength enhancement was observed in concrete mixes made with bagasse ash. This enhancement was seen in concrete mixes that were prepared with bagasse ash at all sieve size with amount up to 10% replacement by volume. Moreover, Bagasse ash retains at 45 μm sieve size showed better result than others sieve size. Thus it can be said that decreasing the sieve size can improve the property of concrete It can therefore be concluded that up to 10% replacement of cement by bagasse ash results increase in strength and higher replacement could also be used with a slight reduction in the performance of the concrete.

description: Events in the world are inherently multimodal. A ball bouncing provides correlated auditory and visual information to the senses. How are such events neurally represented? One possibility is that these distinct sources are integrated into a coherent percept of the event. Alternatively, auditory and visual information may be separably represented, but linked via semantic knowledge or their correlated temporal structure. We investigated this using event-related fMRI. Participants viewed and/or heard 2.5s environmental events, for example, paper ripping or door knocking, in two unimodal and three multimodal conditions: Auditory only (ripping sound) Visual only (movie of paper ripping) Congruent Auditory/Visual (sound + movie of same instance) Semantically Incongruent A/V (ripping sound + movie of knocking) Temporally Incongruent A/V (ripping sound + movie of different ripping instance) Of interest is the encoding of Congruent and Semantically Incongruent A/V events. The integrated proposal predicts sensory brain regions showing a differential response to semantic incongruencies, while under the separate representation account, there should be no difference. Critically, this multimodal response must be stronger than the responses for unimodal stimuli. We also consider whether integration processes function at the level of semantic congruity or at a fine-grained temporal level that binds sound to vision. The Congruent and Temporally Incongruent comparison addresses whether integrated multimodal responses arise due to A/V information from within the same semantic category. Alternatively, a single event gives rise to a high correlation between onsets, offsets, and temporal structures between domains. Such correlated information may be the “glue” that allows the brain to combine perceptually-distinct information into coherent representations of events. Preliminary results provide support for the perceptual integration of auditory and visual information originating from a common source, that is, one in which there is a correlation between the temporal structure across modalities.

description: As people learn more facts about a concept, those facts become more difficult to remember. This is called the fan effect, where fan refers to the number of facts known about a concept. Increasing fan has been shown to decrease accuracy and increase response time and left ventrolateral prefrontal cortex (VLPFC) activity during retrieval. In this study, participants learned 36 arbitrary person–location pairings and made recognition decisions while we recorded brain activity using fMRI. We separately manipulated the fan of each person and location, as well as the training procedure with which each pair was studied. In the person focus condition, participants studied pairs with a picture of the person's face and used the person as a retrieval cue during training. In the location focus condition, participants studied pairs with a picture of the location and used the location as a retrieval cue during training. We found that the fan of the focused cue had a greater effect on response time, accuracy, and left VLPFC activity during retrieval than the fan of the unfocused cue. We also found that the parahippocampal place area (PPA) was more active during the recognition of pairs studied in the location focus condition, but not when the fan of the location was high. Overall, we found opposite effects of fan on VLPFC and PPA that were modulated by cue focus.

description: The ongoing development of the fifth-generation (5G) wireless communication networks is reaching a commercial stage, which is capable of providing high reliability, low latency, and high transmission rate services. However, the fast development in terminal devices accompanying the surge of mobile users brings tremendous traffic. Meanwhile, diverse service requirements are starting to rise from emerging applications. These requirements encompass global coverage, ultra-high data rate transmission, ultra-low latency, ultra-dense connectivity, ultra-reliable and secure links, pervasive intelligence, etc. Given the constraint of licensed bandwidth, it may struggle to support diverse requirements of novel applications solely through physical layer advancements in the future. In this background, a promising avenue is to improve the utilization of available resources by investigating new communication paradigms and developing intelligent resource management schemes for the next-generation network. We first review and investigate two categories of potential paradigms and their corresponding resource management schemes in the next-generation network, including heterogeneous symbiotic communication (Het-SC) network and semantic communication (SemCom) network. Additionally, we separately investigate different resource management schemes under two specific Het-SC scenarios and two SemCom scenarios. Concretely, for Het SC scenarios, we propose a deep reinforcement learning (DRL)- based resource management scheme to trade-off different communication resources (especially bandwidth) via service/resource exchanges among symbiotic devices (SDs). In addition to communication resource management, we investigate and propose a DRL-based communication caching resource trade-off scheme for heterogeneous devices in a D2D communication network, which can improve the utilization of both communication and caching resources, as well as provide satisfied services for user equipments (UEs). Furthermore, as a preliminary investigation of resource management in SemCom scenarios, a DRL-based communication-computational resource trade-off scheme is proposed for end-to-end (E2E) SemCom-empowered artificial intelligence (AI)-generated content (AIGC) transmission. The scheme is capable of ensuring required latency and content quality with limited communication resources while improving computation resource utilization. In parallel, to maximize the utilization of communication and computational resources and provide high-quality services in multimodal SemCom (M SemCom) networks, we propose a DRL-based communication-computational resource trade off scheme to adjust the computing workload and transmitted data size in SemCom. Through comprehensive simulations, intelligent resource trade-off schemes are examined within diverse promising scenarios. Numerical results validate the performance gains achieved by the DRL-based resource trade-off schemes in terms of service quality and resource utilization.

description: Current research on the neurobiological bases of reading points to the privileged role of a ventral cortical network in visual word processing. However, the properties of this network and, in particular, its selectivity for orthographic stimuli such as words and pseudowords remain topics of significant debate. Here, we approached this issue from a novel perspective by applying pattern-based analyses to functional magnetic resonance imaging data. Specifically, we examined whether, where and how, orthographic stimuli elicit distinct patterns of activation in the human cortex. First, at the category level, multivariate mapping found extensive sensitivity throughout the ventral cortex for words relative to false-font strings. Secondly, at the identity level, the multi-voxel pattern classification provided direct evidence that different pseudowords are encoded by distinct neural patterns. Thirdly, a comparison of pseudoword and face identification revealed that both stimulus types exploit common neural resources within the ventral cortical network. These results provide novel evidence regarding the involvement of the left ventral cortex in orthographic stimulus processing and shed light on its selectivity and discriminability profile. In particular, our findings support the existence of sublexical orthographic representations within the left ventral cortex while arguing for the continuity of reading with other visual recognition skills.

description: We investigate continuous time random walks with truncated $α$-stable trapping times. We prove distributional ergodicity for a class of observables; namely, the time-averaged observables follow the probability density function called the Mittag--Leffler distribution. This distributional ergodic behavior persists for a long time, and thus the convergence to the ordinary ergodicity is considerably slower than in the case in which the trapping-time distribution is given by common distributions. We also find a crossover from the distributional ergodic behavior to the ordinary ergodic behavior.

description: The Weyl semimetallic compound Eu2Ir2O7 along with its hole doped derivatives (which is achieved by substituting trivalent Eu by divalent Sr) are investigated through transport, magnetic and calorimetric studies. The metal-insulator transition (MIT) temperature is found to get substantially reduced with hole doping and for 10% Sr doping the composition is metallic down to temperature as low as 5 K. These doped compounds are found to violate the Mott-Ioffe-Regel condition for minimum electrical conductivity and show distinct signature of non-Fermi liquid behavior at low temperature. The MIT in the doped compounds does not correlate with the magnetic transition point and Anderson-Mott type disorder induced localization may be attributed to the ground state insulating phase. The observed non-Fermi liquid behavior can be understood on the basis of disorder induced distribution of spin orbit coupling parameter which is markedly different in case of Ir4+ and Ir5+ ions.

description: We study the q-deformed Knizhnik-Zamolodchikov equation in path representations of the Temperley-Lieb algebras. We consider two types of open boundary conditions, and in both cases we derive factorised expressions for the solutions of the qKZ equation in terms of Baxterised Demazurre-Lusztig operators. These expressions are alternative to known integral solutions for tensor product representations. The factorised expressions reveal the algebraic structure within the qKZ equation, and effectively reduce it to a set of truncation conditions on a single scalar function. The factorised expressions allow for an efficient computation of the full solution once this single scalar function is known. We further study particular polynomial solutions for which certain additional factorised expressions give weighted sums over components of the solution. In the homogeneous limit, we formulate positivity conjectures in the spirit of Di Francesco and Zinn-Justin. We further conjecture relations between weighted sums and individual components of the solutions for larger system sizes.

To this end we calculate the imaginary part of the dynamical electron-hole pair susceptibility and analyze the wave-vector and energy dependence of excitonic resonances emerging in the band gap. We thereby confirm the existence of the exciton insulator and its exciton environment within a generic two-band lattice model with local Coulomb attraction.

Creators: name: Cozmuta, Adrian
Publisher: name: Dual Degree of Doctor of Philosophy in  Economic and Social History at the University of Glasgow and Economics at Kyoto University
Year: 2024

description: This study examines the underlying processes behind the airline privatisation experience in Europe through the cases of three main European airlines, British Airways, Lufthansa, and Air France as well as the resulting developments in terms of industry dynamics. The study examines various privatisation processes, including intra-firm planning related to rationalisation and operational strategy to industry-wide developments, such as alliances and mergers. The framework of Competition-Cooperation-Consolidation (“3C’s”) is developed in this study to best represent how the post-deregulated industry has changed since the 1980s.

The study reveals that in terms of intra-firm dynamics, Lufthansa and Air France followed a similar strategy of rationalisation ahead of privatisation as that of the first fully privatised British Airways. The British Airways rationalisation strategy has become an industry standard for cost-cutting and pre-flotation recovery. Furthermore, Lufthansa and Air France have followed the British Airways post-privatisation scale strategy of investments, acquisitions, and code-sharing agreements with partnered airlines. The aim has been to survive 1990s liberalisation and the Single European Aviation Market 1997 competition drive.

In terms of industry-wide dynamics, all three airlines have developed their code-sharing agreements to pursue cooperation within the industry given the pressures of deregulation. These partnerships evolved into the three main airline alliances, Star Alliance, Oneworld, and SkyTeam. As a result, closer cooperation led to alliances and eventually mergers like the Lufthansa Group, with the aim of consolidating market power within the international market. Consequently, the “3C’s” framework is exemplified as the common configuration that British Airways, Lufthansa, and Air France have followed and contributed toward.

This study also shows how the state has been involved in the privatisation process and since. A continued presence of the state in the functioning of these flag carriers has been noted despite privatisation due to strategic reasoning and, in the Air France case, political ambivalence related to privatisation. The most recent COVID-19 bailouts exemplify how the state continues to be involved, even if indirectly in the case of British Airways, often leading to a “too big to fail” type scenario and flag carrier favouritism. This aspect brings about concerns about continued government intervention within industry, resulting in distorted competition accusations.

description: Unravelling the nature of doping-induced transition between a Mott insulator and a weakly correlated metal is crucial to understanding novel emergent phases in strongly correlated materials. For this purpose, we study the evolution of spectral properties upon doping Mott insulating states, by utilizing the cluster perturbation theory on the Hubbard and t-J-like models. Specifically, a quasi-free dispersion crossing the Fermi level develops with small doping, and it eventually evolves into the most dominant feature at high doping levels. Although this dispersion is related to the free electron hopping, our study shows that this spectral feature is in fact influenced inherently by both electron-electron correlation and spin exchange interaction: the correlation destroys coherence, while the coupling between spin and mobile charge restores it in the photoemission spectrum. Due to the persistent impact of correlations and spin physics, the onset of gaps or the high-energy anomaly in the spectral functions can be expected in doped Mott insulators.

description: We consider the question of perfect local distinguishability of mutually orthogonal bipartite quantum states, with the property that every state can be specified by a unitary operator acting on the local Hilbert space of Bob. We show that if the states can be exactly discriminated by one-way LOCC where Alice goes first, then the unitary operators can also be perfectly distinguished by an orthogonal measurement on Bob's Hilbert space. We give examples of sets of N<=d maximally entangled states in $d \otimes d $ for d=4,5,6 that are not perfectly distinguishable by one-way LOCC. Interestingly for d=5,6 our examples consist of four and five states respectively. We conjecture that these states cannot be perfectly discriminated by two-way LOCC.

description: Computation of document image quality metrics often depends upon the availability of a ground truth image corresponding to the document. This limits the applicability of quality metrics in applications such as hyperparameter optimization of image processing algorithms that operate on-the-fly on unseen documents. This work proposes the use of surrogate models to learn the behavior of a given document quality metric on existing datasets where ground truth images are available. The trained surrogate model can later be used to predict the metric value on previously unseen document images without requiring access to ground truth images. The surrogate model is empirically evaluated on the Document Image Binarization Competition (DIBCO) and the Handwritten Document Image Binarization Competition (H-DIBCO) datasets.

description: Quasi-periodic modulations of the stellar light curve may result from dark spots crossing the visible stellar disc. Since the release of the first TESS sector the possibility of examining such quasi-periodic modulations by assumed dark spots has increased. Thanks to this observations we tried to detect starspot coverage of low mass stars with visible variability of their luminosity. Using the light curves from TESS satellite and the new, BASSMAN package to fit spot models of different complexities, will constructed starspots distribution on individual stars. These models will then be tested to reveal a connection between the starspots and the stellar flares, in order to provide insight into the overall stellar magnetic field. Here we present results of modeling of starspots on GJ 1243 with our new tool and compare the results with the previous reconstructions of the spatial distribution.
Spaces of Collibration: The Governance and Metagovernance of Failure
Creators: name: Jones, Martin
Publisher: name: Sociologica
Year: 2024

description: This essay offers a geographical political economy explanation to the failed state of the local and regional economic growth and development in England’s regions. The essay advances the field of inquiry known as metagovernance and increasingly multispatial metagovernance, i.e., how complex problems of economic life and the existence of various failures — market failure, state failure, and governance failure — necessitates a focus on governance coordination and its complex geographies. Taking metagovernance as a point of departure, the term “spaces of collibration”, taken initially from the work of Dunsire (1993, 1994 & 1996) and developed by Jessop (2016a, 2016b & 2020), is deployed to capture how altering the relative balance within and between different modes of spatial coordination through state intervention shapes the governance of local and regional economic development. Collibration critically gets behind how uneven development and state intervention in sub-national economic development is managed by creating an unstable equilibrium of compromise, which in turn helps to explain the governance of failure.

The Sphere Packing Bound For Memoryless Channels

Year: 2018
Subjects: subject: Information Theory (cs.IT)

description: Sphere packing bounds (SPBs) ---with prefactors that are polynomial in the block length--- are derived for codes on two families of memoryless channels using Augustin's method: (possibly non-stationary) memoryless channels with (possibly multiple) additive cost constraints and stationary memoryless channels with convex constraints on the composition (i.e. empirical distribution, type) of the input codewords. A variant of Gallager's bound is derived in order to show that these sphere packing bounds are tight in terms of the exponential decay rate of the error probability with the block length under mild hypotheses.

description: Dendritic polyelectrolytes constitute high potential drugs and carrier systems for biomedical purposes, still their biomolecular interaction modes, in particular those determining the binding affinity to proteins, have not been rationalized. We study the interaction of the drug candidate dendritic polyglycerol sulfate (dPGS) with serum proteins using Isothermal Titration Calorimetry (ITC) interpreted and complemented with molecular computer simulations. Lysozyme is first studied as a well-defined model protein to verify theoretical concepts, which are then applied to the important cell adhesion protein family of selectins. We demonstrate that the driving force of the strong complexation originates mainly from the release of only a few condensed counterions from the dPGS upon binding. The binding constant shows a surprisingly weak dependence on dPGS size (and bare charge) which can be understood by colloidal charge-renormalization effects and by the fact that the magnitude of the dominating counterion-release mechanism almost exclusively depends on the interfacial charge structure of the protein-specific binding patch. Our findings explain the high selectivity of P- and L- selectins over E-selectin for dPGS to act as a highly anti-inflammatory drug. The entire analysis demonstrates that the interaction of proteins with charged polymeric drugs can be predicted by simulations with unprecedented accuracy. Thus, our results open new perspectives for the rational design of charged polymeric drugs and carrier systems.
The topology of an open manifold with radial curvature bounded from below by a model surface with finite total curvature and examples of model surfaces

description: We will construct surfaces of revolution with finite total curvature whose Gauss curvatures are not bounded. Such a surface of revolution is employed as a reference surface of comparison theorems in radial curvature geometry. Moreover, we will prove that a complete non-compact Riemannian manifold M is homeomorphic to the interior of a compact manifold with boundary, if the manifold M is not less curved than a non-compact model surface of revolution, and if the total curvature of the model surface is finite and less than $2π$. Hence, in the first result mentioned above, we may treat a much wider class of metrics than that of a complete non-compact Riemannian manifold whose sectional curvature is bounded from below by a constant.

Membrane theory of entanglement dynamics from holography

description: Recently, a minimal membrane description of the entanglement dynamics of large regions in generic chaotic systems was conjectured in arXiv:1803.00089. Analytic results in random circuits and spin chain numerics support this theory. We show that the results found by the author in arXiv:1612.00082 about the dynamics of entanglement entropy in theories with a holographic dual can be reformulated in terms of the same minimal membrane, providing strong evidence that the membrane theory describes all chaotic systems. We discuss the implications of our results for tensor network approaches to holography and the holographic renormalization group.

Logarithm of the scale factor as a generalised coordinate in a lagrangian for dark matter and dark energy

description: A lagrangian for the $k-$ essence field is set up with canonical kinetic terms and incorporating the scaling relation of [1]. There are two degrees of freedom, {\it viz.},$q(t)= ln\enskip a(t)$ ($a(t)$ is the scale factor) and the scalar field $ϕ$, and an interaction term involving $ϕ$ and $q(t)$.The Euler-Lagrange equations are solved for $q$ and $ϕ$. Using these solutions quantities of cosmological interest are determined. The energy density $ρ$ has a constant component which we identify as dark energy and a component behaving as $a^{-3}$ which we call dark matter. The pressure $p$ is {\it negative} for time $t\to \infty$ and the sound velocity $c_{s}^{2}={\partial p\over\partialρ} << 1$. When dark energy dominates, the deceleration parameter $Q\to -1$ while in the matter dominated era $Q\sim {1\over 2}$. The equation of state parameter $w={p\over ρ}$ is shown to be consistent with $w={p\overρ}\sim -1$ for dark energy domination and during the matter dominated era we have $w\sim 0$. Bounds for the parameters of the theory are estimated from observational data. Keywords: k-essence models, dark matter, dark energy PACS No: 98.80.-k
