description: The formation and evolution of leading jets can be described by jet functions which satisfy non-linear DGLAP-type evolution equations. Different than for inclusive jets, the leading jet functions constitute normalized probability densities for the leading jet to carry a longitudinal momentum fraction relative to the initial fragmenting parton. We present a parton shower algorithm which allows for the calculation of leading-jet cross sections where logarithms of the jet radius and threshold logarithms are resummed to next-to-leading logarithmic (NLL$'$) accuracy. By calculating the mean of the leading jet distribution, we are able to quantify the average out-of-jet radiation, the so-called jet energy loss. When an additional reference scale is measured, we are able to determine the energy loss of leading jets at the cross section level which is identical to parton energy loss at leading-logarithmic accuracy. We identify several suitable cross sections for an extraction of the jet energy loss and we present numerical results for leading subjets at the LHC. In addition, we consider hemisphere and event-wide leading jets in electron-positron annihilation similar to measurements performed at LEP. Besides the average energy loss, we also consider its variance and other statistical quantities such as the KL divergence which quantifies the difference between quark and gluon jet energy loss. We expect that our results will be particularly relevant for quantifying the energy loss of quark and gluon jets that propagate through hot or cold nuclear matter.

Reliability analysis of structural concrete elements
Creators: name: Jonsson, Gisli
Publisher: name: University of British Columbia
Year: 2008

description: The reliability of reinforced concrete elements and design iceberg impact loads for offshore structures were studied. The reliability program RELAN was used to perform FORM reliability analysis for reinforced beams subjected to bending, and for a reinforced concrete wall from the Hibernia offshore structure subjected to complex loading. RELAN was also used to establish the probabilistic distribution of ice impact loads. To study the reliability of concrete beams accounting for the variability of the intervening variables, and in order to determine the theoretical flexural capacity of concrete beam, computer program TIN was developed. TIN uses a strain compatibility approach accounting for the non-linear stress-strain relationships of concrete and reinforcing steel. As a pilot study on the reliability of concrete elements, a beam designed according to the Canadian concrete code was analyzed with the objective of evaluating the effect of different spans and reinforcing steel ratios on the reliability of the beam. To study the reliability of more complex elements, an element from the icewall of the Hibernia offshore structure was used. The theoretical strength of the wall element was evaluated with program SHELL474. In order to link SHELL474 to RELAN for the reliability study, the main subroutine in SHELL474 was modified. Since one of the major factors in reliability studies of concrete offshore structures are the uncertainties associated with extreme environmental load conditions, the statistics for ice impact loads for the Hibemia structure were derived using RELAN and applications of energy conservation principles. For the purpose of deriving the ice load distributions to evaluate the reliability of the Hibemia icewall element, the program PROB, which is a product of the reliability program RELAN and the energy conservation principles, was developed.

description: We discuss approximations of the vertex coupling on a star-shaped quantum graph of $n$ edges in the singular case when the wave functions are not continuous at the vertex and no edge-permutation symmetry is present. It is shown that the Cheon-Shigehara technique using $δ$ interactions with nonlinearly scaled couplings yields a $2n$-parameter family of boundary conditions in the sense of norm resolvent topology. Moreover, using graphs with additional edges one can approximate the ${n+1\choose 2}$-parameter family of all time-reversal invariant couplings.

The method can also deal with both massless and massive particles, thereby encompassing ultra-relativistic and mildly-relativistic regimes alike. The computational performance of the method for the simulation of relativistic flows across the aforementioned regimes is discussed in detail, along with prospects of future applications for Quark-Gluon Plasma, electron flows in graphene and systems in astrophysical contexts.

description: We prove that potential conservation laws have characteristics depending only on local variables if and only if they are induced by local conservation laws. Therefore, characteristics of pure potential conservation laws have to essentially depend on potential variables. This statement provides a significant generalization of results of the recent paper by Bluman, Cheviakov and Ivanova [J. Math. Phys., 2006, V.47, 113505]. Moreover, we present extensions to gauged potential systems, Abelian and general coverings and general foliated systems of differential equations. An example illustrating possible applications of proved statements is considered. A special version of the Hadamard lemma for fiber bundles and the notions of weighted jet spaces are proposed as new tools for the investigation of potential conservation laws.

description: The emission mechanism for hard $γ$-ray spectra from supernova remnants (SNRs) is still a matter of debate. Recent multi-wavelength observations of TeV source HESS J1912+101 show that it is associated with an SNR with an age of $\sim 100$ kyrs, making it unlikely produce the TeV $γ$-ray emission via leptonic processes. We analyzed Fermi observations of it and found an extended source with a hard spectrum. HESS J1912+101 may represent a peculiar stage of SNR evolution that dominates the acceleration of TeV cosmic rays. By fitting the multi-wavelength spectra of 13 SNRs with hard GeV $γ$-ray spectra with simple emission models with a density ratio of GeV electrons to protons of $\sim 10^{-2}$, we obtain reasonable mean densities and magnetic fields with a total energy of $\sim 10^{50}$ ergs for relativistic ions in each SNR. Among these sources, only two of them, namely SN 1006 and RCW 86, favor a leptonic origin for the $γ$-ray emission. The magnetic field energy is found to be comparable to that of the accelerated relativistic ions and their ratio has a tendency of increase with the age of SNRs. These results suggest that TeV cosmic rays mainly originate from SNRs with hard $γ$-ray spectra.

description: We have identified three ultraluminous X-ray sources (ULXs) hosted by globular clusters (GCs) within NGC 1316's stellar system. These discoveries bring the total number of known ULXs in GCs up to 20. We find that the X-ray spectra of the three new sources do not deviate from the established pattern of spectral behaviour of the other known GC ULXs. The consistency of the X-ray spectral behaviour for these sources points to multiple paths of formation and evolution mechanisms for these rare and unique sources. Using the now larger sample of GC ULXs, we compare the optical properties of the entire known population of GC ULXs to other GCs across five galaxies and find that the properties of clusters that host ULXs are quite different from the typical clusters. Lastly, any trend of GC ULXs being preferentially hosted by metal-rich clusters is not strongly significant in this sample.

description: We present 24 micron Spitzer/MIPS photometric observations of the ~50 Myr open cluster IC 2391. Thirty-four cluster members ranging in spectral type from B3-M5 were observed in the central square degree of the cluster. Excesses indicative of debris disks were discovered around 1 A star, 6 FGK stars, and possibly 1 M dwarf. For the cluster members observed to their photospheric limit, we find a debris disk frequency of 10 (-3,+17)% for B-A stars and 31 (-9,+13)% for FGK stars using a 15% relative excess threshold. Relative to a model of decaying excess frequency, the frequency of debris disks around A-type stars appears marginally low for the cluster's age while that of FGK stars appears consistent. Scenarios that may qualitatively explain this result are examined. We conclude that planetesimal activity in the terrestrial region of FGK stars is common in the first ~50 Myr and decays on timescales of ~100 Myr. Despite luminosity differences, debris disk evolution does not appear to depend strongly on stellar mass.

Thermodynamic uncertainty relation for first-passage times on Markov chains

Year: 2021
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We derive a thermodynamic uncertainty relation (TUR) for first-passage times (FPTs) on continuous time Markov chains. The TUR utilizes the entropy production coming from bidirectional transitions, and the net flux coming from unidirectional transitions, to provide a lower bound on FPT fluctuations. As every bidirectional transition can also be seen as a pair of separate unidirectional ones, our approach typically yields an ensemble of TURs. The tightest bound on FPT fluctuations can then be obtained from this ensemble by a simple and physically motivated optimization procedure. The results presented herein are valid for arbitrary initial conditions, out-of-equilibrium dynamics, and are therefore well suited to describe the inherently irreversible first-passage event. They can thus be readily applied to a myriad of first-passage problems that arise across a wide range of disciplines.
Seaweeds As Sustainable Food Sources: A Green Alternative to Traditional Agriculture

Publisher: name: The Science world a Monthly e magazine
Year: 2024

description: Introduction

Seaweeds are increasingly recognized as a sustainable food source, offering several environmental and nutritional benefits compared to traditional agriculture. Here’s a quick overview of why they’re considered a green alternative:

Environmental Benefits

1.     Low Carbon Footprint: Seaweeds absorb carbon dioxide as they grow, which can help mitigate climate change. They also don’t require land, freshwater, or fertilizers, reducing their overall environmental impact (Yong et al.,2022).

2.     Ocean Health: Cultivating seaweeds can improve water quality by absorbing excess nutrients and carbon. This can help prevent problems like algal blooms and ocean acidification.

3.     Biodiversity Support: Seaweed farms can create habitats for marine life, supporting biodiversity in the ocean.

description: Deactivation of broad quasi-one-dimensional dibosonic molecules is analyzed. Within integrable Lieb-Liniger-McGuire (LLMG) model an exact expression does not demonstrate suppression of the deactivation at low collision energies. Solution of Faddeev equations demonstrates that when a Feshbach resonance lifts the symmetry of the LLMG model the deactivation becomes suppressed. This effect shows a way for formation of a stable gas of dibosonic Feshbach molecules.

description: We present scanning tunneling microscopy and spectroscopy of the newly discovered superconductor CaC$_6$. The tunneling conductance spectra, measured between 3 K and 15 K, show a clear superconducting gap in the quasiparticle density of states. The gap function extracted from the spectra is in good agreement with the conventional BCS theory with $Δ(0)$ = 1.6 $\pm$ 0.2 meV. The possibility of gap anisotropy and two-gap superconductivity is also discussed. In a magnetic field, direct imaging of the vortices allows to deduce a coherence length in the ab plane $ξ_{ab}\simeq$ 33 nm.

description: We overview the concept of dynamical phase transitions in isolated quantum systems quenched out of equilibrium. We focus on non-equilibrium transitions characterized by an order parameter, which features qualitatively distinct temporal behaviour on the two sides of a certain dynamical critical point. Dynamical phase transitions are currently mostly understood as long-lived prethermal phenomena in a regime where inelastic collisions are incapable to thermalize the system. The latter enables the dynamics to substain phases that explicitly break detailed balance and therefore cannot be encompassed by traditional thermodynamics. Our presentation covers both cold atoms as well as condensed matter systems. We revisit a broad plethora of platforms exhibiting pre-thermal DPTs, which become theoretically tractable in a certain limit, such as for a large number of particles, large number of order parameter components, or large spatial dimension. The systems we explore include, among others, quantum magnets with collective interactions, $ϕ^4$ quantum field theories, and Fermi-Hubbard models. A section dedicated to experimental explorations of DPTs in condensed matter and AMO systems connects this large variety of theoretical models.

description: We have investigated random submonolayer films of 3d transition metals on W(001). The tight-binding linear muffin-tin orbital method combined with the coherent potential approximation was employed to calculate the electronic structure of the films. We have estimated local magnetic moments and the stability of different magnetic structures, namely the ferromagnetic order, the disordered local moments and the non-magnetic state, by comparing the total energies of the corresponding systems. It has been found that the magnetic moments of V and Cr decrease and eventually disappear with decreasing coverage. On the other hand, Fe retains approximately the same magnetic moment throughout the whole concentration range from a single impurity to the monolayer coverage. Mn is an intermediate case between Cr and Fe since it is non-magnetic at very low coverages and ferromagnetic otherwise.

description: Dwarf early-type galaxies (ETGs) display a rich diversity in their photometric, structural, and dynamical properties. In this work, we address their structural complexity by studying with deep imaging a sample of nine dwarf ETGs from the Virgo galaxy cluster, characterized by having faint disk features, such as bars and spiral arms, which lie mostly hidden within the bright diffuse light of the galaxies. We present a new, robust method that aims to identify and extract the disk substructure embedded in these dwarf ETGs. The method consists in an iterative procedure that gradually separates a galaxy image into two components; the bright, dominant diffuse component, and the much fainter, underlying disk component. By applying it to the dwarf ETG sample, we quantify their disk substructure and find that its relative contribution to the total galaxy light ranges between 2.2 to 6.4% within two effective radii. We test the reliability of the method, and prove that it is accurate in recovering the disk substructure we introduce in mock galaxy images, even at low disk-to-total light fractions of a few percent. As a potential application of the method, we perform a Fourier analysis on the extracted disk substructures and measure the orientation, length, and strength of the bars, and the pitch angle and strength of the spiral arms. We also briefly discuss a scenario based on the numerical simulations presented in our companion paper, Brought to Light II: Smith et al. 2021, in which we investigate the origins of the substructure in such dwarf systems.

Oblique wave reflection from a model rubble-mound breakwater
Creators: name: Papps, David Arnold
Publisher: name: University of British Columbia
Year: 2008

description: This thesis investigates the characteristics of oblique wave reflection from a model rubble-mound breakwater. An experimental investigation of the reflection of obliquely incident regular, irregular and multi-directional waves, undertaken at the Hydraulics Laboratory of the National Research Council of Canada in Ottawa, is described. A method of analysis, which uses a least squares fit to measurements from three wave probes to estimate the reflection coefficient and the reflected phase lag for regular wave tests, is extended to the case of oblique wave reflection. In the regular wave tests, the wave height, wave period, and angle of incidence were varied in order to determine relationships between the reflection characteristics and parameters describing the incident wave characteristics. Results show that both the reflection coefficient and the reflected phase lag are dependent on the depth to wavelength ratio and the angle of incidence. Reflection coefficients estimated from the analysis of irregular wave tests are also presented and are compared to reflection coefficients measured in regular wave tests, showing good agreement. For multi-directional waves, directional spectra of the incident and reflected wave fields were obtained using a maximum likelihood fit to measurements from five wave probes. Directionality results are presented for one multi-directional wave test showing increased directional spreading of the reflected wave field as compared to the incident wave field.

description: Despite recent advances in representation learning in hypercomplex (HC) space, this subject is still vastly unexplored in the context of graphs. Motivated by the complex and quaternion algebras, which have been found in several contexts to enable effective representation learning that inherently incorporates a weight-sharing mechanism, we develop graph neural networks that leverage the properties of hypercomplex feature transformation. In particular, in our proposed class of models, the multiplication rule specifying the algebra itself is inferred from the data during training. Given a fixed model architecture, we present empirical evidence that our proposed model incorporates a regularization effect, alleviating the risk of overfitting. We also show that for fixed model capacity, our proposed method outperforms its corresponding real-formulated GNN, providing additional confirmation for the enhanced expressivity of HC embeddings. Finally, we test our proposed hypercomplex GNN on several open graph benchmark datasets and show that our models reach state-of-the-art performance while consuming a much lower memory footprint with 70& fewer parameters. Our implementations are available at https://github.com/bayer-science-for-a-better-life/phc-gnn.

description: In our companion paper (Brought to Light I: Michea et al. 2021), we reveal spectacular spiral galaxy-like features in deep optical imaging of nine Virgo early-type dwarf galaxies, hidden beneath a dominating smooth stellar disk. Using a new combination of approaches, we find that bar- and spiral-like features contribute 2.2-6.4% of the total flux within 2 R$_{\rm{eff}}$. In this study, we conduct high resolution simulations of cluster harassment of passive dwarf galaxies. Following close pericenter passages of the cluster core, tidal triggering generates features in our model disks that bear a striking resemblance to the observed features. However, we find the disks must be highly rotationally supported (V$_{\rm{peak}}/σ_0 \sim 3$), much higher than typically observed. We propose that some early-type dwarfs may contain a few percent of their mass in a cold, thin disk which is buried in the light of a hot, diffuse disk, and only revealed when they undergo tidal triggering. The red optical colors of our sample do not indicate any recent significant star formation, and our simulations show that very plunging pericenter passages (r$_{\rm{peri}}<0.25$r$_{\rm{vir}}$) are required for tidal triggering. Thus, many cluster early-type dwarfs with less plunging orbits may host a yet undetected cold stellar disk component. We discuss possible origin scenarios and consider why similar mass star-forming galaxies in the field are significantly more thin disk dominated than in our cluster sample.

description: The null curvature condition (NCC) is the requirement that the Ricci curvature of a Lorentzian manifold be nonnegative along null directions, which ensures the focusing of null geodesic congruences. In this note, we show that the NCC together with the causal structure significantly constrain the metric. In particular, we prove that any conformal rescaling of a vacuum spacetime introduces either geodesic incompleteness or negative null curvature, provided the conformal factor is non-constant on at least one complete null geodesic. In the context of bulk reconstruction in AdS/CFT, our results combined with the technique of light-cone cuts can be used in vacuum spacetimes to reconstruct the full metric in regions probed by complete null geodesics reaching the boundary. For non-vacuum spacetimes, our results constrain the conformal factor, giving an approximate reconstruction of the metric.

description: The tomographic approach to quantum mechanics is revisited as a direct tool to investigate violation of Bell-like inequalities. Since quantum tomograms are well defined probability distributions, the tomographic approach is emphasized to be the most natural one to compare the predictions of classical and quantum theory. Examples of inequalities for two qubits an two qutrits are considered in the tomographic probability representation of spin states.

description: The subject of this Ph.D. thesis is the Greek mercenaries in the service of revolutionary France during the years 1789-1815. The thesis is composed by two parts. In the first part, we examined the creation of the first Greek mercenary corps in the service of France in the Ionian Islands from 1797 to 1799 and the origin, creation and presence of the Greek and Coptic Legions during the French campaign in Egypt from 1798 to 1801. We also studied the creation of the "Chasseurs d'Orient" battalion in France during the years 1801-1806 and their participation in the French campaign to Dalmatia from 1806 to 1809 as well as the creation and organization of the rest of the mercenary formations in the Ionian Islands, in particular the Albanian regiment and the Septinsular battalion from 1809 to 1815. In the second part of the thesis, we dealt with several aspects of the mercenary everyday life(including their tactics and military gear), the financial, political and social forces at play that underlie the phenomenon og Greek(and Balkan) mercenaries in the service of the French Republic and more general issues of their mentality and political ideology. The working hypothesis was thoroughly re-evaluated and examined at the end of the thesis followed by an exhaustive list of archival and literature sources
Distribution of local Lyapunov exponents in spin-glass dynamics

description: We investigate the statistical properties of local Lyapunov exponents which characterize magnon localization in the $d=1$ Heisenberg-Mattis spin glass (HMSG) at zero temperature, by means of a connection to a suitable version of the Fokker-Planck (F-P) equation. We consider the local Lyapunov exponents (LLE), in particular the case of {\em instantaneous} LLE. We establish a connection between the transfer-matrix recursion relation for the problem, and an F-P equation governing the evolution of the probability distribution of the instantaneous LLE. The closed-form (stationary) solutions to the F-P equation are in excellent accord with numerical simulations, for both the unmagnetized and magnetized versions of the HMSG. Scaling properties for non-stationary conditions are derived from the F-P equation in a special limit (in which diffusive effects tend to vanish), and also shown to provide a close description to the corresponding numerical-simulation data.

Object-oriented software development in structural engineering

Publisher: name: University of British Columbia

description: The recent emergence of the object-oriented paradigm has created a very powerful methodology to aid software developers in the creation of complex applications. This technology is quite common in fields such as computer science and computer engineering but still remains relatively unexplored in more traditional disciplines such as Civil Engineering. The paradigm enforces several basic necessities required by complex, modern software applications. These include management of complexity, data modelling, information hiding, software reusability, and software evolution. The purpose of this thesis is to give an overview of the object-oriented paradigm. This discussion includes a review of the necessary requirements of an object-oriented language. This is followed by the presentation of a software diagramming notation which can aid in the data modelling and design of a software system before coding is started. Also presented is a discussion on the pragmatics of object-oriented development. A universal structural analysis preprocessor called "Cross Link" is developed by the author to demonstrate the application of the object paradigm. Cross Link is intended to provide a unified, easy to use, graphical preprocessing environment that can be used as a front end for any type of finite element analysis programme or CADD package. This is achieved through the implementation of a powerful macro programming language which allows users to manipulate the finite element database in many different ways.

description: Binaries play a critical role in the formation, evolution, and fundamental properties of planets, stars, and stellar associations. Observational studies in these areas often include a mix of observations aimed at detecting or ruling out the presence of stellar companions. Rarely can non-detections rule out all possible binary configurations. Here we present MOLUSC, our framework for constraining the range of properties of unseen companions using astrometric, imaging, and velocity information. We showcase the use of MOLUSC on a number of systems, ruling out stellar false positives in the signals of HIP67522b, and DS Tuc Ab. We also demonstrate how MOLUSC could be used to predict the number of missing companions in a stellar sample using the ZEIT sample of young planet hosts. Although our results are not significant, with a larger sample MOLUSC could be used to see if close-in planets are less common in young binary systems, as is seen for their older counterparts.

description: We describe an experimental and computational investigation of the ordered and disordered phases of a vibrating thin, dense granular layer composed of identical metal spheres. We compare the results from spheres with different amounts of inelasticity and show that inelasticity has a strong effect on the phase diagram. We also report the melting of an ordered phase to a homogeneous disordered liquid phase at high vibration amplitude or at large inelasticities. Our results show that dissipation has a strong effect on ordering and that in this system ordered phases are absent entirely in highly inelastic materials.

description: L’objectif de cet article est d’identifier les déterminants de la pauvreté subjective en Côte d’Ivoire en période post-conflit. Pour ce faire, un échantillon de 5 060 ménages, issu de la base de données EHCVM 2018 a été utilisé. Cette étude s’est servie d’un modèle logit ordonné et des résultats significatifs ont été obtenus. Premièrement ils indiquent que les variables socio-démographiques telles que l’accès aux infrastructures de santé, de transport, à l’éducation, la nationalité et le secteur d’activité agricole et celui du transport ont un effet positif sur la perception de la pauvreté par contre l’accès à un logement décent a un effet négatif sur la perception de la pauvreté. Deuxièmement, les chefs de ménage ayant été affectés par le conflit de 2002 ou celui de 2010 ont une perception négative de la pauvreté. Sur la base de ces résultats des recommandations ont été faites.
