description: Within the framework of a high-twist approach, we calculate the next-to-leading order (NLO) perturbative QCD corrections to the transverse momentum broadening in semi-inclusive hadron production in deeply inelastic $e+A$ collisions, as well as lepton pair production in $p+A$ collisions. With explicit calculations of both real and virtual contributions, we verify, for the first time, the factorization theorem at twist 4 in NLO for the nuclear-enhanced transverse momentum weighted differential cross section and demonstrate the universality of the associated twist-4 quark-gluon correlation function. We also identify the QCD evolution equation for the twist-4 quark-gluon correlation function in a large nucleus, which can be solved to determine the scale dependence of the jet transport parameter in the study of jet quenching.

description: We study the neutrino oscillation physics performance of the Long-Baseline Neutrino Experiment (LBNE) in various configurations. In particular, we compare the case of a surface detector at the far site augmented by a near detector, to that with the far site detector placed deep underground but no near detector. In the latter case, information from atmospheric neutrino events is also utilized. For values of θ_{13} favored by reactor experiments and a 100 kt-yr exposure, we find roughly equivalent sensitivities to the neutrino mass hierarchy, the octant of θ_{23}, and to CP violation. We also find that as the exposure is increased, the near detector helps increase the sensitivity to CP violation substantially more than atmospheric neutrinos.

description: We present a decomposition technique that uses non-deterministic circuits to approximate an arbitrary single-qubit unitary to within distance $ε$ and requires significantly fewer non-Clifford gates than existing techniques. We develop "Repeat-Until-Success" (RUS) circuits and characterize unitaries that can be exactly represented as an RUS circuit. Our RUS circuits operate by conditioning on a given measurement outcome and using only a small number of non-Clifford gates and ancilla qubits. We construct an algorithm based on RUS circuits that approximates an arbitrary single-qubit $Z$-axis rotation to within distance $ε$, where the number of $T$ gates scales as $1.26\log_2(1/ε) - 3.53$, an improvement of roughly three-fold over state-of-the-art techniques. We then extend our algorithm and show that a scaling of $2.4\log_2(1/ε) - 3.28$ can be achieved for arbitrary unitaries and a small range of $ε$, which is roughly twice as good as optimal deterministic decomposition methods.

description: We decompose, within an ARCH framework, the daily volatility of stocks into overnight and intra-day contributions. We find, as perhaps expected, that the overnight and intra-day returns behave completely differently. For example, while past intra-day returns affect equally the future intra-day and overnight volatilities, past overnight returns have a weak effect on future intra-day volatilities (except for the very next one) but impact substantially future overnight volatilities. The exogenous component of overnight volatilities is found to be close to zero, which means that the lion's share of overnight volatility comes from feedback effects. The residual kurtosis of returns is small for intra-day returns but infinite for overnight returns. We provide a plausible interpretation for these findings, and show that our Intra-Day/Overnight model significantly outperforms the standard ARCH framework based on daily returns for Out-of-Sample predictions.
Revenge of the 'Neurds': Characterizing Creative Thought in terms of the Structure and Dynamics of Memory

description: There is cognitive, neurological, and computational support for the hypothesis that defocusing attention results in divergent or associative thought, conducive to insight and finding unusual connections, while focusing attention results in convergent or analytic thought, conducive to rule-based operations. Creativity appears to involve both. It is widely believed that it is possible to escape mental fixation by spontaneously and temporarily engaging in a more associative mode of thought. The resulting insight (if found) may be refined in a more analytic mode of thought. The questions addressed here are: (1) how does the architecture of memory support these two modes of thought, and (2) what is happening at the neural level when one shifts between them? Recent advances in neuroscience shed light on this. Activated cell assemblies are composed of multiple neural cliques, groups of neurons that respond differentially to general or context-specific aspects of a situation. I refer to neural cliques that would not be included in the assembly if one were in an analytic mode, but would be if one were in an associative mode, as neurds. It is posited that the shift to a more associative mode of thought is accomplished by recruiting neurds that respond to abstract or atypical microfeatures of the problem or task. Since memory is distributed and content-addressable, this fosters the forging of associations to potentially relevant items previously encoded in those neurons. Thus it is proposed that creative thought not by searching a space of predefined alternatives and blindly tweaking those that hold promise, but by evoking remotely associated items through the recruitment of neurds in a distributed, content-addressable memory.

description: The Casimir-Polder interaction of ground-state and excited atoms with graphene is investigated with the aim to establish whether graphene systems can be used as a shield for vacuum fluctuations of an underlying substrate. We calculate the zero-temperature Casimir-Polder potential from the reflection coefficients of graphene within the framework of the Dirac model. For both doped and undoped graphene we show limits at which graphene could be used effectively as a shield. Additional results are given for AB-stacked bilayer graphene.

description: Let W be a Coxeter group. In this paper, we establish that, up to going to some finite index normal subgroup W_0 of W, any two cyclically reduced expressions of conjugate elements of W_0 only differ by a sequence of braid relations and cyclic shifts. This thus provides a simple description of conjugacy classes in W_0. As a byproduct of our methods, we also obtain a characterisation of straight elements of W, namely of those elements w in W for which $\ell(w^n)=n\ell(w)$ for any integer n. In particular, we generalise previous characterisations of straight elements within the class of so-called cyclically fully commutative (CFC) elements, and we give a shorter and more transparent proof that Coxeter elements are straight.

description: How did the human species evolve the capacity not just to communicate complex ideas to one another but to hold such conversations from across the globe, using remote devices constructed from substances that do not exist in the natural world, the raw materials for which may have been hauled up from the bowels of the earth? How did we come to be so intelligent? Research at the interface of psychology, biology, anthropology, archaeology, and cognitive science is culminating in an increasingly sophisticated understanding of how human intelligence evolved. Studies of the brains of living humans and great apes and the intellectual abilities they support are enabling us to assess what is unique about human intelligence and what we share with our primate relatives. Examining the habitats and skeletons of our ancestors gives cues as to environmental, social, and anatomical factors that both constrain and enable the evolution of human intelligence. Relics of the past also have much to tell us about the thoughts, beliefs, and abilities of the individuals who invented and used them.

Futuristic multimodal business model for European freight railways: A survival and revival strategy
Creators: name: Jain, Anuradha
Publisher: name: Zenodo
Year: 2023

description: Abstract European freight rail though environmentally favorable and economic over long distances has still low market share. This is due to its failure to deliver key customer requirements: reliability, quality of service, a door-to-door service and price/cost. The purpose of this paper is to discuss the status of rail freight and to suggest innovative IT based solutions which support the achievement of European Commission objectives on modal shift to revive and increase the rail market share i.e. bringing 30% of road traffic beyond 300 Kms to multimodal transport modes. It does so by drawing lessons from electronic trading in power exchanges to present a multimodal transport exchange. Method The paper first depicts the key strategic issues of European freight railway market using the porter’s five forces analysis at a high level. It then discusses why lessons can be drawn from power exchanges and why the model is from today’s perspective futuristic. Results The important strategic and organizational aspects of power exchanges applicable to the multimodal transport exchanges with relevant modification. The description of the model includes the expected market behavior due to the introduction of such exchanges, a basis for future research. Conclusions The paper fosters the idea, that a multimodal transport exchange model using criteria’s of environment friendliness and economical transport for transport selection can help in the revival and survival of rail. Especially when road traffic is aggregated using automatic algorithms and transported on rail. This will increase the rail market share and also reduce emissions.

description: Analysing the strategic alignment of software requirements primarily provides assurance to stakeholders that the software-to-be will add value to the organisation. Additionally, such analysis can improve a requirement by disambiguating its purpose and value, thereby supporting validation and value-oriented decisions in requirements engineering processes, such as prioritisation, release planning, and trade-off analysis. We review current approaches that could enable such an analysis. We focus on Goal Oriented Requirements Engineering methodologies, since goal graphs are well suited for relating software goals to business goals. However, we argue that unless the extent of goal-goal contribution is quantified with verifiable metrics, goal graphs are not sufficient for demonstrating the strategic alignment of software requirements. Since the concept of goal contribution is predictive, what results is a forecast of the benefits of implementing software requirements. Thus, we explore how the description of the contribution relationship can be enriched with concepts such as uncertainty and confidence, non-linear causation, and utility. We introduce the approach using an example software project from Rolls-Royce.

description: This paper summarizes efforts to computationally model two transitions in the evolution of human creativity: its origins about two million years ago, and the 'big bang' of creativity about 50,000 years ago. Using a computational model of cultural evolution in which neural network based agents evolve ideas for actions through invention and imitation, we tested the hypothesis that human creativity began with onset of the capacity for recursive recall. We compared runs in which agents were limited to single-step actions to runs in which they used recursive recall to chain simple actions into complex ones. Chaining resulted in higher diversity, open-ended novelty, no ceiling on the mean fitness of actions, and greater ability to make use of learning. Using a computational model of portrait painting, we tested the hypothesis that the explosion of creativity in the Middle/Upper Paleolithic was due to onset of con-textual focus: the capacity to shift between associative and analytic thought. This resulted in faster convergence on portraits that resembled the sitter, employed painterly techniques, and were rated as preferable. We conclude that recursive recall and contextual focus provide a computationally plausible explanation of how humans evolved the means to transform this planet.

description: The covariant spectator quark model is applied to the $γ^\ast N \to N^\ast(1520)$ reaction. The valence quark contributions to the electromagnetic form factors and helicity transition amplitudes are estimated from the covariant structure of the $N^\ast(1520)$ wave function calibrated by the experimental data for large squared momentum transfer $Q^2$. The difference between the model results and the experimental data is then used to parameterize the low $Q^2$ behavior, where meson cloud effects are assumed to dominate. This parametrization can be very useful for future studies of the reaction, as well as for the extension of the transition form factors to the timelike region.

description: Recently, realizations of Kitaev physics have been sought in the A2IrO3 family of honeycomb iridates, originating from oxygen-mediated exchange through edge-shared octahedra. However, for the j = 1/2 Mott insulator in these materials exchange from direct d-orbital overlap is relevant, and it was proposed that a Heisenberg term should be added to the Kitaev model. Here we provide the generic nearest-neighbour spin Hamiltonian when both oxygen-mediated and direct overlap are present, containing a bond dependent off-diagonal exchange in addition to Heisenberg and Kitaev terms. We analyze this complete model using a combination of classical techniques and exact diagonalization. Near the Kitaev limit, we find new magnetic phases, 120 degree and incommensurate spiral order, as well as extended regions of zigzag and stripy order. Possible applications to Na2IrO3 and Li2IrO3 are discussed.

It is a lower bound for the classical Hermite constant, and these two constants coincide when $K$ has class number one. Using the geometric tools developed by Mendoza and Vogtmann for their study of the homology of the Bianchi groups, we compute the projective Hermite constants for those $K$ whose absolute discriminants are less than 70, and determine the hermitian forms that attain the projective Hermite constants in these cases. A comparison of the projective hermitian constant with some other generalizations of the classical Hermite constant is also given.

description: The goals of this research were to (1) determine if there is agreement both amongst viewers, and between viewers and the performer, about the extent to which performances are authentic, and (2) ascertain whether or not performers and/or viewers can distinguish between authenticity and skill. An authentic performance is one that is natural or genuine, while an inauthentic performance feels faked, forced, or imitative. Study participants were asked to rate the authenticity and skill level of a series of videotaped performances by dancers and stand-up comedians. Performers also rated their own performances. Authenticity ratings amongst viewers were significantly positively correlated. Ratings between viewers and performers were not significant but all positive. A higher correlation between ratings of both authenticity and skill of performances for viewers than for performers suggests that viewers make less of a distinction between authenticity and skill than performers. The relationship between authenticity and creativity is discussed.

We show that maximum coherence between the ground state |1> and the excited state |2> could be achieved using a train of femtosecond pulses. In addition, it is possible to control the trajectory of the atoms in an atomic beam by using the same scheme. The robustness of the scheme against the variation of the pulse parameters is also investigated.

We focus on systems with constant dispersion, and present three different models that describe atomic Bose-Einstein condensates in different experimentally relevant settings. For these models, we identify exact rogue wave solutions. Our analytical findings are corroborated by direct numerical integration of the original equations, performed by two different schemes. Very good agreement between numerical results and analytical predictions for the emergence of the rogue waves is identified. Additionally, the nontrivial fate of small numerically induced perturbations to the exact rogue wave solutions is also discussed.

description: Carbon capture and storage intends to inject anthropogenic carbon dioxide from large point sources into the geologic formations for emissions mitigation. In geological carbon sequestration, it is critical to understand the behavior of carbon dioxide as it displaces subsurface, resident fluids during storage to assure its safety and permanence. The multiphase nature of carbon dioxide displacing saline water over long-term periods of post-injection relies heavily on the buoyancy forces arising from the density contrast between CO2 and saline water and the capillary forces controlled by the pore geometry at the pore scale. The competition of those governing forces controls the field-scale migration and confinement of CO2 in reservoir formations. In this study, we use high fidelity pore-scale simulations of multiphase flow to investigate this phenomenon in porous geometries representative of sedimentary rock formations. A computational fluid dynamic technique known as the volume of fluid method is taken to model the buoyancy-driven flow of CO2 in subsurface reservoirs. There are many computational burdens in these simulations. High-resolution meshes with a high number of grid cells are required to capture the complexity of the pore morphology leading to a high computational burden when considering the number of necessary simulated timesteps. Even reducing the domain size of the models to an effective 2-dimensional (2-d) structure with an area less than 1 cm2, nearly prohibitive computational time is needed. Furthermore, to replicate the capillary dominated flow, low velocity values are needed. However, the slower the flowrate, the more an interfacial issue known as spurious currents occurs, leading to numerical instabilities. To handle this numerical issue, simulations with smaller timesteps are required, but in tandem with the slow velocities, computational expense is further compounded. The usage of TACC’s parallel processing resources along with optimization techniques facilitates solutions and results that inform us about the fundamental mechanics of this flow.

Three expert painters created four paintings, each of which was the artist's interpretation of one of four different pieces of instrumental music. Participants were able to identify which paintings were inspired by which pieces of music at statistically significant above chance levels. The findings support the hypothesis that creative ideas can exist in an at least somewhat domain independent state of potentiality and become more well defined as they are actualized in accordance with the constraints of a particular domain.

description: We study the site version of (independent) first-passage percolation on the triangular lattice $\mathbb{T}$. Denote the passage time of the site $v$ in $\mathbb{T}$ by $t(v)$, and assume that $P(t(v)=0)=P(t(v)=1)=1/2$. Denote by $a_{0,n}$ the passage time from $\textbf{0}$ to $(n,0)$, and by $b_{0,n}$ the passage time from $\textbf{0}$ to the halfplane $\{(x,y):x\geq n\}$. We prove that there exists a constant $0

description: Spatial transcriptomics (ST) is an emerging technology that quantifies gene expression at spatial resolution from intact tissue sections. Although ST is enabling unprecedented studies on spatial gene expression, it has posed new challenges to biological data science. A typical ST dataset contains information of ~20K genes from 50K-100K cells. It is challenging to design efficient and scalable algorithms that generate new biological insights from these datasets. Here we feature an efficient and scalable non-negative matrix factorization (NMF) algorithm for identifying “spatial gene modules” (spatial-gems), i.e., groups of genes that express at spatially adjacent locations, in ST data. Spatial-gems are fundamental aspects of multi-cellular organisms. NMF is suitable for this problem since, in theory, NMF can identify the “informative parts” constituting a dataset, e.g., lips and eyes in human facial images and spatial-gems in ST data. The basic NMF formulation, however, can give sub-optimal results for spatial datasets – it ignores spatial locations of data points and thus does not guarantee informative parts that are spatially coherent. Graph-regularized NMF (GNMF) overcomes this issue by constraining the informative parts to comprise spatially adjacent data points. We introduce three changes to tailor the state-of-the-art GNMF algorithm for ST data. First, we statistically determine the optimal number of spatial-gems in an ST dataset. Secondly, we introduce regularizations that minimize the number of genes common between spatial-gems. Finally, we leverage numerical libraries and efficient data structures to obtain a scalable implementation. We benchmarked our GNMF against alternative algorithms on a brain ST dataset. Our algorithm comprehensively charted the spatial-gems in this dataset with a 20x speedup in execution time, making this an attractive tool for large-scale ST consortia like HuBMAP (Human BioMolecular Atlas Program). This tool and our multifaceted approach to enhance efficiency and scalability will be of major interest to the broad userbase of TACC.

description: We tested the hypothesis that threatening situations enhance creativity. 60 participants viewed a series of photographs and rated them on level of threat. They then wrote two short stories: one based on the photograph they rated as most threatening, and the other based on the photograph they rated as least threatening. The stories were rated for level of creativity. Paired samples t-tests revealed that stories based on threatening pictures produced a higher degree of creativity than those based on non-threatening pictures. Theoretical frameworks consistent with these findings are discussed.

description: Abstract: Microalgae of the genus Gambierdiscus are producers of precursors of ciguatoxins (CTXs), which bioaccumulate in the marine trophic chain and are responsible for ciguatera fish poisoning in humans. Ciguatera is a foodborne illness typically known as a tropical disease, but ciguatera cases are being increasingly reported in the North-Eastern Atlantic. The appearance of fish contaminated with CTXs has become more and more common in areas such as the Canary Islands, but the mechanisms underlying the bioaccumulation and biotransformation of the CTXs in this region are still poorly discerned (Soliño & Costa, 2020). The study presented here is part of the European project “Ciguarisk” and has the objective to assess cell growth and toxin production of two Gambierdiscus strains from the Atlantic region selected for fish feeding experiments, i.e., G. excentricus IRTA-SMM-17-429 and G. carolineanus BEA1923. Cell growth was performed in culture flasks under the same culture conditions, using a semi-continuous batch approach. The culture method is aimed to harvest the highest biomass production possible for use in dietary exposure experiments in fish. Two culture media (L1 and F2) were evaluated for their influence on the growth of the strains. Both media were suitable for culturing Gambierdiscus, although some slight differences were observed in growth rates and cell behaviour. G. excentricus IRTA-SMM-17-429 presented slower growth with respect to G. carolineanus BEA1923 in all conditions tested. Ciguatoxins were extracted from fresh biomass samples and pre-purified using liquid-liquid partitioning. CTX-like toxicity of the strains was screened using the neuroblastoma neuro-2a assay (Caillaud et al., 2010). Preliminary data suggest that G. excentricus IRTA-SMM-17-429 is more toxic than G. carolineanus BEA1923. These results presented in this study are in accordance with previous studies on other strains of G. carolinianus and G. excentricus (Pisapia et al., 2017). Further studies will focus on culture optimization and scale-up, quantitation of the toxic content, and micro-encapsulation of the biomass for the feeding experiments. The results obtained from this project will ultimately help to a better understanding of the bioaccumulation and biotransformation of CTXs in the food chain in the Atlantic region.

description: We use Pseudo Quantum Electrodynamics (PQED) in order to describe the full electromagnetic interaction of the p-electrons of graphene in a consistent 2D formulation. We first consider the effect of this interaction in the vacuum polarization tensor or, equivalently, in the current correlator. This allows us to obtain the dc conductivity after a smooth zero-frequency limit is taken in Kubo's formula.Thereby, we obtain the usual expression for the minimal conductivity plus corrections due to the interaction that bring it closer to the experimental value. We then predict the onset of an interaction-driven spontaneous Quantum Valley Hall effect (QVHE) below a critical temperature of the order of $0.05$ K. The transverse (Hall) valley conductivity is evaluated exactly and shown to coincide with the one in the usual Quantum Hall effect. Finally, by considering the effects of PQED, we show that the electron self-energy is such that a set of P- and T- symmetric gapped electron energy eigenstates are dynamically generated, in association with the QVHE.

description: Timing the arrival of radio pulses from an array of rapidly spinning neutron stars (Pulsars) is a promising method for detecting gravitational waves (GWs) in the ultra-low frequency regime (10!" Hz to 10!# Hz), primarily from supermassive (billion solar mass and above) black hole binaries . It is expected that next-generation radio telescopes, namely, the Five-Hundred-Meter Aperture Spherical Radio Telescope (FAST) and the Square Kilometer Array (SKA), will grow the number of well-timed pulsars to 𝑂(10$). This will result in greater distance reach for GW sources, uncovering multiple resolvable GW sources in addition to an unresolved population. The multisource resolution problem for PTAs poses a unique set of data analysis challenges such as nonuniformly sampled data, a large number of so-called pulsar phase parameters that arise from the inaccurately measured distances to the pulsars, and poor separation of signals in the Fourier domain due to a small number of cycles in the observed waveforms. We are developing an end-to-end software pipeline for addressing these challenges. The core idea is the iterative subtraction of individually estimated GW sources from the data. However, multiple stages of refinement are needed improve the sample of identified sources, including a novel approach that mitigates spurious sources by cross-checking the outputs from two semi-independent refinement steps. The performance of the current version of the pipeline was quantified on simulated data from PTAs containing 10% and 10$ pulsars, leading to state-of-the-art results in all cases. For example, the fraction of sources found by the method that correspond to true sources in the simulated data exceeds 78% and 93% for a large-scale (with 10$ pulsars and 200 sources) and a midscale (with 10% pulsars and 100 sources) PTA, respectively. The pipeline is currently implemented as a mix of Matlab and parallelized C-code running on TACC resources.

description: In this paper we give a new proof of the ELSV formula. First, we refine an argument of Okounkov and Pandharipande in order to prove (quasi-)polynomiality of Hurwitz numbers without using the ELSV formula (the only way to do that before used the ELSV formula). Then, using this polynomiality we give a new proof of the Bouchard-Mariño conjecture. After that, using the correspondence between the Givental group action and the topological recursion coming from matrix models, we prove the equivalence of the Bouchard-Mariño conjecture and the ELSV formula (it is a refinement of an argument by Eynard).
