description: In his 2016 book, The Fourth Industrial Revolution, Klaus Schwab, the founder of the World Economic Forum, predicted the advent of the next technological revolution, underpinned by artificial intelligence (AI). He argued that, like its predecessors, the AI revolution would wield global socio-economic repercussions. Schwab’s writing was prescient. In November 2022, OpenAI released ChatGPT, a large language model (LLM) embedded with a conversation agent. The reception was phenomenal, with more than 100 million people accessing it during the first two months. Not only did ChatGPT garner widespread personal use, but hundreds of corporations promptly incorporated it and other LLMs to optimize their processes and to enable new products. In this blog post, adapted from our recent whitepaper, we examine the capabilities and limitations of LLMs. In a future post, we will present four case studies that explore potential applications of LLMs. Despite the consensus that this technology revolution will have global consequences, experts differ on whether the impact will be positive or negative. On one hand, OpenAI’s stated mission is to create systems that benefit all of humanity. On the other hand, following the release of ChatGPT, more than a thousand researchers and technology leaders signed an open letter calling for a six-month hiatus on the development of such systems out of concern for societal welfare. As we navigate the fourth industrial revolution, we find ourselves at a juncture where AI, including LLMs, is reshaping sectors. But with new technologies come new challenges and risks. In the case of LLMs, these include disuse - the untapped potential of opportune LLM applications; misuse - dependence on LLMs where their usage may be unwarranted; and abuse - exploitation of LLMs for malicious intent. To harness the advantages of LLMs while mitigating potential harms, it is imperative to address these issues. This post begins by describing the fundamental principles underlying LLMs. We then delve into a range of practical applications, encompassing data science, training and education, research, and strategic planning. Our objective is to demonstrate high leverage use-cases and identify strategies to curtail misuse, abuse, and disuse, thus paving the way for more informed and effective use of this transformative technology.

description: The solar-wind magnetosphere interaction primarily occurs at altitudes where the dipole component of Earth's magnetic field is dominating. The disturbances that are created in this interaction propagate along magnetic field lines and interact with the ionosphere-thermosphere system. At ionospheric altitudes, the Earth's field deviates significantly from a dipole. North-South asymmetries in the magnetic field imply that the magnetosphere ionosphere-thermosphere (M-I-T) coupling is different in the two hemispheres. In this paper we review the primary differences in the magnetic field at polar latitudes, and the consequences that these have for the M-I-T coupling. We focus on two interhemispheric differences which are thought to have the strongest effects: 1) A difference in the offset between magnetic and geographic poles in the Northern and Southern Hemispheres, and 2) differences in the magnetic field strength at magnetically conjugate regions. These asymmetries lead to differences in plasma convection, neutral winds, total electron content, ion outflow, ionospheric currents and auroral precipitation.

description: Due to the balanced ratio of soluble and insoluble fiber, small amount of lipids and sugar, and the low
 energy value, sugar beet fibers provide excellent physiological benefits to human body and their physicochemical
 characteristics allow a better compounding whit the other ingredients of the product. Sugar beet fibers are derived
 from sugar beet pulp, which is obtained in the course of the technological processing of sugar beet following the
 process of extraction of sucrose from the sweet pulp. The aim of this investigation was the characterization of the
 sugar beet fiber for bread and toast production, as well as the definition of exact drying temperature of sugar beet
 fiber to reach the best physicochemical properties for implementation in bread. In all samples the chemical
 composition: soluble and insoluble fibers, ash and protein content are determined. During experimental work the
 physicochemical (water holding capacity, aw value, colour parameters), and microbiological characteristics (total
 number of bacteria, aerobe and anaerobe bacteria, yeast and mold) of sugar beet pulp dried on different temperatures:
 at 55, 65 and 75 °C in the chamber drier are defined. The content of the total fiber content is about 75%, regardless
 of drying temperature. In sugar beet fibers dominate nonsoluble fiber. Samples dried in the chamber dryer have
 highwater holding capacity (from 488% to 524%) depend on temperature. By drying the samples in chamber dryer
 at55°C, the highest lightness of the dried sugar beet pulp were reached (L* =71). The presence of the sporogenaous
 aerobic and anaerobic bacterias are determined in all samples.

description: We report the experimental evidence of the existence of a random attractor in a fully developed turbulent swirling flow. By defining a global observable which tracks the asymmetry in the flux of angular momentum imparted to the flow, we can first reconstruct the associated turbulent attractor and then follow its route towards chaos. We further show that the experimental attractor can be modeled by stochastic Duffing equations, that match the quantitative properties of the experimental flow, namely the number of quasi-stationary states and transition rates among them, the effective dimensions, and the continuity of the first Lyapunov exponents. Such properties can neither be recovered using deterministic models nor using stochastic differential equations based on effective potentials obtained by inverting the probability distributions of the experimental global observables. Our findings open the way to low dimensional modeling of systems featuring a large number of degrees of freedom and multiple quasi-stationary states.

description: This article considers nonparametric regression models with multivariate covariates and with responses missing at random. We estimate the regression function with a local polynomial smoother. The residual-based empirical distribution function that only uses complete cases, i.e. residuals that can actually be constructed from the data, is shown to be efficient in the sense of Hájek and Le Cam. In the proofs we derive, more generally, the efficient influence function for estimating an arbitrary linear functional of the error distribution; this covers the distribution function as a special case. We also show that the complete case residual-based empirical distribution function admits a functional central limit theorem. The article concludes with a small simulation study investigating the performance of the complete case residual-based empirical distribution function.

description: User involvement in transport decision-making (often referred to as ‘public participation’) has been actively encouraged by government for many years. However, the methods used for engaging the public are mostly traditional (e.g. questionnaires, consultation documents and focus groups) with very little use of creative techniques. Furthermore, the level of involvement is generally ‘passive’ (i.e. agreeing pre-established local authority priorities) rather than ‘active’ (i.e. generation of problem areas, priorities or potential solutions using participatory approaches).‘Participatory design’ encompasses a broad range of methods and is often resource-heavy but leads to user-centric outcomes. If it is to be more widely employed in the development of sustainable transport solutions, then there needs to be more evidence of its value in this context, more exploration of which participants and which methods are beneficial, and more exploration of novel ways to engage with the travelling public. To address the latter, there is an opportunity to utilise the affordances of technology (e.g. mobile accessibility, location-enabled, immediacy, content-creation, mass-engagement) to understand what is needed, to co-create ideas and to collaborate in the pursuance of these solutions. It is this overlapping of direct user involvement, innovative approaches and technology affordances that is explored in this thesis in the context of sustainable transport innovations.This thesis presents ten publications that, as a collection, show how the author has investigated the role of user participation in the development of transport service innovations. This body of work makes a contribution to knowledge predominantly in participatory design but also in other domains including transport studies, crowdsourcing and grassroots innovation. The work has provided evidence of the benefits of user participation at different stages of the design process including problem identification via crowdsourced content, identifying novel and diverse solutions using generative methods and actively creating solutions using ‘volunteered information’.

description: Analyzing the achievable rate of molecular communication via diffusion (MCvD) inherits intricacies due to its nature: MCvD channel has memory, and the heavy tail of the signal causes inter symbol interference (ISI). Therefore, using Shannon's channel capacity formulation for memoryless channel is not appropriate for the MCvD channel. Instead, a more general achievable rate formulation and system model must be considered to make this analysis accurately. In this letter, we propose an effective ISI-aware MCvD modeling technique in 3-D medium and properly analyze the achievable rate.

description: We present a method for the calculation of photoemission spectra in terms of reduced density matrices. We start from the spectral representation of the one-body Green's function G, whose imaginary part is related to photoemission spectra, and we introduce a frequency-dependent effective energy that accounts for all the poles of G. Simple approximations to this effective energy give accurate spectra in model systems in the weak as well as strong correlation regime. In real systems reduced density matrices can be obtained from reduced density-matrix functional theory. Here we use this approach to calculate the photoemission spectrum of bulk NiO: our method yields a qualitatively correct picture both in the antiferromagnetic and paramagnetic phases, contrary to mean-field methods, in which the paramagnet is a metal.

description: The railway industry is a complex system with a continuously changing environment. Within 2018, passenger trains covered 520 billion kilometres carrying 1700 million passengers. During the period 1994-2007 there were seven fatal accidents on the UK railway network, four of which were Signals Passed at Danger (SPAD) events. These were Cowden in 1994, Watford Junction in 1996; Southall in 1997 and Ladbroke Grove in 1999. SPAD events vary in severity and whilst most are not fatal there is the potential to cause serious injuries to passengers and train staff and damage to railway infrastructure. The rapid technological advances due to these fatal incidents of the late 1990’s has seen an improvement in safety systems; however, these changes have had a limited impact on the occurrence of SPAD events. The number of SPAD events has fluctuated since 2003-04 with an average of 307 SPAD events occurring each year. Between 2017 and 2018, a SPAD occurred on average 5-6 times each week, totalling 295 SPADs in the year. Whilst the developments in safety systems and infrastructure has caused a decline in fatalities of both passengers and workforce each SPAD event has the potential to be catastrophic. Therefore, the aim of this thesis was to investigate human and organisational factors contributing to SPAD events and to explore the underlying stakeholder perceptive of the barriers to learning from SPAD events to identify why SPADs are continuing to be a near daily occurrence on the UK railway network.

Naive methods based on term frequency weighing perform on par with specialized session models. In addition, we investigate the viability of lexical query models in the setting of session search. We give important insights into the potential and limitations of lexical query modeling for session search and propose future directions for the field of session search.

Optimal design of building envelopes for passive structural control
Creators: name: Pipitone, Giovanni
Publisher: name: Loughborough University
Year: 2020
Subjects: subject: 129999 Built Environment and Design not elsewhere classified
subject: FOS: Civil engineering

description: In the civil engineering field, passive control devices are used to prevent structures from damages caused by a variety of events such as earthquakes, winds, blast and traffic. A control strategy based on the use of \ac{DSF} as passive vibration absorbers has been recently proposed in order to mitigate vibrations induced by environmental hazards on tall buildings.
In this Thesis, the multi-hazard design of different \ac{DSF} layouts subject to seismic and wind actions is investigated through several numerical applications. Both hazards are modelled in a probabilistic framework, taking into account prescriptions of building codes. Firstly, the optimal \ac{DSF} design is found studying the two load cases separately. Particularly, the seismic excitation is modelled using recorded accelerograms and then as a stochastic process defined by its \ac{PSD} function. In the first case, the optimal configurations of the \ac{DSF} are obtained solving four optimisation problems: two minimising the statistics of the structural response (displacement and accelerations) due to each single earthquake record, and two taking into account the average response to the full set of records analysed. In the second case, the objective of the optimisation is the minimisation of the variance of the displacements of the main structure, constrained with respect to the maximum relative displacement between the structure itself and the DSF. Taking advantage of the reduced computational effort, the optimisation has been performed varying the peak ground acceleration, herein considered as intensity measure. The results shown that the proposed layout is capable to absorb the seismic vibration inside a well identified operative range.
A similar approach is used for the wind hazard. However, in this case, the variance of the accelerations of the top storey of the building is used to define the optimisation objective function. A velocity range in which the DSF can reduce the vibrations induced by the wind actions has been found.Similarities in the mathematical definition of the optimisation problem for the two cases (seismic and wind hazards) allow for approaching the multi-hazard design of the DSF as a multi-objective optimisation problem. In the latter, the Pareto fronts of optimal solutions have been determined varying load intensities and identifying three hazard ranges in which the DSF-dynamic behaviour tends to be different. \\
All the analyses have been conducted considering four different layout of the DSF formed by either one single panel or multiple panels spanning a finite number of storeys. The design problem aims to find the optimal damping ratio and flexural stiffness of the \ac{DSF} and optimal the stiffness of the connection elements. Finally, a comparison among the proposed \ac{DSF} layouts is carried out aiming to identify the best configuration.

description: We intensively studied the flare activity on the stellar object KIC011764567. The star was thought to be solar type, with a temperature of $T_{eff} = (5640 \pm 200)\,$K, $\log(g) = (4.3 \pm 0.3)\,$dex and a rotational period of Prot 22 d (Brown et al. 2011). High resolution spectra turn the target to an evolved object with Teff = (5300 \pm 150) K, a metalicity of $[m/H] = (-0.5 \pm 0.2)$, a surface gravity of $log(g) = (3.3 \pm 0.4)\,$dex, and a projected rotational velocity of $v sin i = (22 \pm 1)\,kms^{-1}$. Within an observing time span of 4 years we detected 150 flares in Kepler data in an energy range of $10^{36} - 10^{37}$ erg. From a dynamical Lomb-Scargle periodogram we have evidence for differential rotation as well as for stellar spot evolution and migration. Analysing the occurrence times of the flares we found hints for a periodic flare frequency cycle of $430 - 460 $d, the significance increases with an increasing threshold of the flares equivalent duration. One explanation is a very short activity cycle of the star with that period. Another possibility, also proposed by others in similar cases, is that the larger flares may be triggered by external phenomena, such as magnetically interaction with an unseen companion. Our high resolution spectra show that KIC011764567 is not a short period binary star.
Steady-state entanglement between distant quantum dots in photonic crystal dimers

description: We show that two spatially separated semiconductor quantum dots under resonant and continuous-wave excitation can be strongly entangled in the steady-state, thanks to their radiative coupling by mutual interaction through the normal modes of a photonic crystal dimer. We employ a quantum master equation formalism to quantify the steady-state entanglement by calculating the system {\it negativity}. Calculations are specified to consider realistic semiconductor nanostructure parameters for the photonic crystal dimer-quantum dots coupled system, determined by a guided mode expansion solution of Maxwell equations. Negativity values of the order of 0.1 ($20\%$ of the maximum value) are shown for interdot distances that are larger than the resonant wavelength of the system. It is shown that the amount of entanglement is almost independent of the interdot distance, as long as the normal mode splitting of the photonic dimer is larger than their linewidths, which becomes the only requirement to achieve a local and individual qubit addressing. Considering inhomogeneously broadened quantum dots, we find that the steady-state entanglement is preserved as long as the detuning between the two quantum dot resonances is small when compared to their decay rates. The steady-state entanglement is shown to be robust against the effects of pure dephasing of the quantum dot transitions. We finally study the entanglement dynamics for a configuration in which one of the two quantum dots is initially excited and find that the transient negativity can be enhanced by more than a factor of two with respect to the steady-state value. These results are promising for practical applications of entangled states at short time scales.

description: In order to compare magnetic and non-magnetic pinning we have nanostructured two superconducting films with regular arrays of pinning centers: Cu (non-magnetic) dots in one case, and Py (magnetic) dots in the other. For low applied magnetic fields, when all the vortices are pinned in the artificial inclusions, magnetic dots prove to be better pinning centers, as has been generally accepted. Unexpectedly, when the magnetic field is increased and interstitial vortices appear, the results are very different: we show how the stray field generated by the magnetic dots can produce an effective reduction of the penetration length. This results in strong consequences in the transport properties, which, depending on the dot separation, can lead to an enhancement or worsening of the transport characteristics. Therefore, the election of the magnetic or non-magnetic character of the pinning sites for an effective reduction of dissipation will depend on the range of the applied magnetic field.

description: This presentation will describe a case study based on a user-centered software design to develop a visualization of scientometric data in research profiles. The outcome will be a reference implementation for several software systems with application in VIVO research information system software as a starting point. One of the objectives is to achieve research profile ownership by enabling researchers to adjust individual visualizations, indicators and data sources publicly displayed on their online profiles. For the study, we combined qualitative interviews and workshops with focus groups, which included researchers from four academic disciplines (i.e., engineering, the humanities, the natural sciences and mathematics as well as the social sciences) and three career levels (i.e., research assistants, doctoral researchers and professors) in the German national research system. By national research system, we do not refer to a Current Research Information Systems (CRIS), but the system of all researchers that publish research outputs in Germany. To begin with, we completed 16 semi-structured interviews with researchers from all four academic disciplines. Following that, two workshops were conducted with focus groups consisting of 10 researchers from the natural sciences and mathematics as well as engineering. Due to COVID-19, virtual workshops with a similar number of researchers from the humanities and social sciences are currently being planned as an alternative. Our study findings thus far suggest that the study participants frequently use research profiles, such as searching for literature, their own profile or profiles of others researchers. Additionally, the analysis suggests differences between academic disciplines, but not between career levels. Qualitative user feedback contributed to an iterative process in software development. The results of this small-scale, non-representative study and the feedback have been applied to develop the visualization as part of our research and development project. The final steps of the user study will include the usability testing of the visualization with researchers.

description: Although many different nonlinear analysis techniques for steel frame structures, they causes the increase in total computational cost. A data-driven approach can then be used to substitute the classic finite element nonlinear analysis including second order methods and inelastic modelling. In this paper, a novel data-driven method using ensemble learning models for geometric and material nonlinear analyses of frame structures is proposed. For this approach, the data acquisition process and machine learning-based models are needed to train a large amount of dataset, which is collected from the nonlinear analysis and a yield surface equation. Ensemble learning algorithms are then used to build the data-driven models. After training, the sequence of plastic hinge formation in steel frame structures can be predicted without any nonlinear analysis process. In that situation, the data-driven model is more effective, especially in practical cases with the lack of experimental information due to limited sensors. The validity of the proposed method has been demonstrated by several numerical examples.

description: We analyze uncertainty relations on finite dimensional Hilbert spaces expressed in terms of classical fidelity, which are stronger then metric uncertainty relations introduced by Fawzi, Hayden and Sen. We establish validity of fidelity uncertainty relations for random unitary matrices with optimal parameters (up to universal constants) which improves upon known results for the weaker notion of metric uncertainty. This result is then applied to locking classical information in quantum states and allows to obtain optimal locking in Hellinger distance, improving upon previous results on locking in the total variation distance, both by strengthening the metric used and by improving the dependence on parameters. We also show that general probabilistic estimates behind the main theorem can be used to prove existence of data hiding schemes with Bayesian type guarantees. As a byproduct of our approach we obtain existence of almost Euclidean subspaces of the matrix spaces $\ell_1^n(\ell_2^m)$ with a better dimension/distortion dependence than allowed in previously known constructions.

Inclusive production of J/$ψ$ and $ψ'$ mesons at the LHC

description: We discuss the prompt production of $J/ψ$ mesons in proton-proton collisions at the LHC within a NRQCD $k_{t}$-factorization approach using Kimber-Martin-Ryskin (KMR) unintegrated gluon distributions (UGDF). We include both direct color-singlet production ($gg \to J/ψ$g) as well as a feed-down from $χ_{c} \to J/ψγ$ and $ψ' \to J/ψX$. The production of the decaying mesons ($χ_{c}$ or $ψ'$)is also calculated within NRQCD $k_{t}$-factorization. The corresponding matrix elements for $gg \to J/ψ$, $gg \to ψ'$ and $gg \to χ_{c}$ include parameters of the nonrelativistic spatial wave functions of quarkonia at $r=0$, which are taken from potential models from the literature. We get the ratio of the corresponding of the cross sections for $χ_{c}(2)$-to-$χ_{c}(1)$ much closer to experimental data than obtained in recent analyses. Differential distributions in rapidity of $J/ψ$ and $ψ'$ are calculated and compared to experimental data of the ALICE and LHCb collaborations. We discuss possible onset of gluon saturation effects at forward/backward rapidities. One can describe the experimental data for $J/ψ$ production within model uncertainties with color-singlet component only. Therefore our theoretical results leave only a relatively small room for the color-octet contributions.

A Paradox of Presence: Time-constraints in the Organ Donation Approach following Brain Death in Contemporary Midwestern America

description: In the current American healthcare system, bereaved families of brain-dead patients are approached almost immediately following the diagnosis, often by nonprofit workers associated with organ procurement organizations (OPOs), to question if the family will authorize organ procurement. The intertwined histories of brain death and organ donation reveal how the implementation of new medical technologies often exists as a socio-political process, where institutional policies and social discourses reshape assumptions about the body’s condition. In this thesis, I explore the experiences of the organ donation approach following brain death through interviews I conducted with donation specialists (DSes) at a Midwest OPO and family decision makers (FDMs). I examine the interviews through an analytic of ‘presence’ and temporality to understand how the ‘active mode of presence’ and language employed by the OPOs in the time-constrained approach for donation renders certain meanings about life, death, and the body’s value perceptible, while other meanings become erased. I show that, in adhering to the rational-utilitarian philosophy upon which western biomedical intuitions operate, the professional work – trainings, actions, and language – employed by the OPO within the ICU dictate a specific, and sometimes contradictory, mode of presence that both creates the immediate moment and defines the body’s social, moral, and economic value within the procurement process. Specifically, I elaborate on the contradictions imposed through language by proposing a new form of the ‘transplant paradox’ (Sharp 2006) not covered in previous research – the paradox of presence. Ultimately, I aim to elucidate how OPO professionals have substantial authority in mediating family’s experiences of brain death to co-produce opinions of organ donation as a sensible outcome. Furthermore, I argue an analysis of temporality (Munn 1992) offers a unique entry point for investigating how meanings of life and death are coordinated and created within this contemporary Midwestern American OPO.
Isentropic 'shock waves' in numerical simulations of astrophysical bodies

description: Strong discontinuities in solutions of the gas dynamic equations under isentropic conditions, i.e., with continuity of entropy at the discontinuity, are examined. Solutions for a standard shock wave with continuity of energy at the discontinuity are compared with those for an isentropic 'shock wave'. It is shown that numerical simulation of astrophysical problems in which high-amplitude shock waves are encountered (supernova explosions, modelling of jets) with conservation of entropy, rather than of energy, leads to large errors in the shock calculations. The isentropic equations of gas dynamics can be used only when there are no strong discontinuities in the solution or when the intensity of the shocks is not high and they do not significantly affect the flow.

description: The Anode Hydrogen Release (AHR) mechanism at interfaces is responsible for the generation of defects, that traps charge carriers and can induce dielectric breakdown in Metal-Oxide-Semiconductor Field Effect Transistors. The AHR has been extensively studied at Si/SiO$_2$ interfaces but its characteristics at metal-silica interfaces remain unclear. In this study, we performed Density Functional Theory (DFT) calculations to study the hydrogen release mechanism at the typical Al/SiO$_2$ metal-oxide interface. We found that interstitial hydrogen atoms can break interfacial Al-Si bonds, passivating a Si $sp^3$ orbital. Interstitial hydrogen atoms can also break interfacial Al-O bonds, or be adsorbed at the interface on aluminum, forming stable Al-H-Al bridges. We showed that hydrogenated O-H, Si-H and Al-H bonds at the Al/SiO$_2$ interfaces are polarized. The resulting bond dipole weakens the O-H and Si-H bonds, but strengthens the Al-H bond under the application of a positive bias at the metal gate. Our calculations indicate that Al-H bonds and O-H bonds are more important than Si-H bonds for the hydrogen release process.
