description: Automatic Identification System (AIS) is a telecommunication sys-tem that allows ships to communicate with each other by sending information regarding their trajectory: location, speed, course and so on. Due to some technical issues, some parts of the transmitted data might be damaged or incomplete. In this paper, we propose a machine learning based approach for detecting AIS data that requires reconstruction. The general idea of the proposed approach, utilizing clustering and mutli-label classification algo-rithms, and its performance are discussed.

description: We describe a probabilistic PARAFAC/CANDECOMP (CP) factorization for multiway (i.e., tensor) data that incorporates auxiliary covariates, SupCP. SupCP generalizes the supervised singular value decomposition (SupSVD) for vector-valued observations, to allow for observations that have the form of a matrix or higher-order array. Such data are increasingly encountered in biomedical research and other fields. We describe a likelihood-based latent variable representation of the CP factorization, in which the latent variables are informed by additional covariates. We give conditions for identifiability, and develop an EM algorithm for simultaneous estimation of all model parameters. SupCP can be used for dimension reduction, capturing latent structures that are more accurate and interpretable due to covariate supervision. Moreover, SupCP specifies a full probability distribution for a multiway data observation with given covariate values, which can be used for predictive modeling. We conduct comprehensive simulations to evaluate the SupCP algorithm. We apply it to a facial image database with facial descriptors (e.g., smiling / not smiling) as covariates, and to a study of amino acid fluorescence. Software is available at https://github.com/lockEF/SupCP .

The role of extracellular Granzyme b in cytotoxic Lymphocyte migration
Creators: name: Prakash, Monica Devi
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Granzyme B (GrB) is a known intracellular cytotoxin that has also been shown to cleave extracellular substrates. GrB is detectable in extracellular fluids under normal, healthy conditions and its levels increase in many disease states that are associated with cytotoxic lymphocyte (eL) hyperactivity. Until now, the role of extracellular GrB has gone unexplained. Among the known extracellular substrates of GrB are several ECM proteins, cleavage of which leads to cell detachment and potential anoikis. Based on the known expression and substrates of GrB, it was hypothesised that extracellular GrB is derived from CLs, which release GrB to degrade extracellular matrix proteins and facilitate cell migration into target tissues. This study showed that zymogen and active forms of GrB are constitutively secreted from CLs, by both conventional and non-conventional pathways. It was subsequently shown that in the absence of GrB, or upon perturbation of its secretion/activity, CLs exhibit a cellautonomous defect in migration through basement membranes in vitro, and in homing to sites of inflammation and infection in vivo. No such defect was evident during interstitial migration. Using a proteomics-iJased approach, it was also demonstrated that GrB cleaves several components of the basement membrane in the context of a complex matrix. The proposed model requires GrB to be released by CLs upon exit from the vasculature (extravasation) and entry to target tissues to break down the basement membrane lining each compartment. This process was previously believed to be predominantly mediated by matrix metalloproteinases, but the studies here reveal the significant contribution made by GrB, and highlight the broader nature of granzyme function.

description: A geometric potential from the kinetic term of a constrained to a curved hyperplane of space-time quantum superconducting condensate is derived. An energy conservation relation involving the geometric field at every material point in the superconductor is demonstrated. At a Josephson junction the energy conservation relation implies the possibility of transforming electric energy into geometric field energy, that is, curvature of space-time. Experimental procedures to verify that the Josephson junction can act as a voltage-to-curvature converter are discussed.

description: Estimates of wave energy fluxes in the solar photosphere and chromosphere suggest that gravity waves carry more energy than co-spatial acoustic waves. This work presents an exploration of the upward propagation of gravity waves from the photosphere to the chromosphere, in a realistic model of the solar atmosphere. The purpose is to determine what happens to upward propagating gravity waves when they reach regions where the magnetic forces dominate. Wave motions are assumed linear and the atmosphere is static and horizontally invariant. Dispersion and ray diagrams provide insight into the mode con¬version mechanism. Numerical solution of the linear adiabatic wave equations quantify wave energy fluxes. The analysis shows that typically even weak magnetic fields cause the gravity wave to reflect back downwards as a slow magneto-acoustic wave well before the Alfven-acoustic equipartition level, and it fails to reach the chromosphere. However, highly inclined magnetic fields allow gravity waves to penetrate the equipartition level and experience substantial mode conversion to up-going Alfven waves, or field-guided acoustic waves. Wave energy fluxes are sensitive to the magnetic field orientation and short radiative damping times, but are insensitive to the magnetic field strengths over the range considered (lOG -100 G). The mode conversion pathways found in adiabatic analyses are preserved in the presence of damping. Mode conversion of gravity waves to Alfven waves is a possible pathway to the upper atmosphere for wave energy. The cause of the high frequency enhancement (the acoustic glory) in seismic power surrounding large active regions with complex field structures is not yet understood. This work presents an investigation of the properties of the seismic emission power and acoustic power of large active regions that have acoustic glories. Helioseismic holography is used to create seismic emission power maps for six large active regions with complex magnetic field structures. Acoustic glories are visible in high-frequency seismic emission power maps (5.0 mHz -7.0 mHz) for all active regions studied. The analysis of acoustic power about large active regions, in high and low frequency regimes, confirms behaviours that are consistent with the findings of previous analyses of smaller active regions. Several new properties of high frequency seismic emission power associated with large active regions are identified: The maximum enhancements in seismic emission and acoustic power occur at different spatial locations; acoustic glories are most prominent in seismic emission power maps in the 5.0 mHz -6.0 mHz bandwidth; the radius of the acoustic glory reduces as frequency increases; and the mean value of high frequency (above 5.0 mHz) seismic emission power for the active regions studied was enhanced at intermediate line-of-sight magnetic flux densities (50 G -300 G).

description: Malnutrition continues to be a major problem with negative implications on economic and human development in many parts of the world, including in Sub-Saharan Africa (SSA). Strengthening promising underutilized crops that are nutrient dense, climate resilient, and locally adaptable is an instrumental approach to enhancing dietary diversity. Due to their nutritional and economic benefits, African Indigenous Vegetables (AIVs) have the potential to contribute to livelihoods and address challenges of food and nutrition insecurity. Despite their importance but due to their perishability, AIVs tend to suffer from high post-harvest losses (PHLs). Effective distribution systems along the value chain have the potential to reduce PHLs for AIVs. We therefore conducted a scoping review on transport systems and coordination in AIVs value chains in SSA. The objectives of this review were to summarize and analyze the focus of research in AIVs transport, to analyze the extent to which the literature synthesizes interactions of sub-components of the chains, and to identify knowledge gaps in AIVs transport literature. Based on the research foci, we categorize the reviewed articles into seven themes. Our analyses indicate that distance to agricultural market is a fundamental aspect of AIVs transportation, as it interacts with transport costs, market participation, produce quality, and profit efficiency. Results show that collective action is instrumental in the coordination of AIVs transportation and that it contributes to cost reduction. Following light exploration of determinants of choice of means of transport, we recommend further research in this area for improvement of transportation in AIVs value chains.

description: The present study is part of the CESAREF (Concerted European action on Sustainable Applications of REFractories) doctoral network, started in late 2022. The aim of the consortium is the contribution to scientific breakthroughs inherent to refractories for steel making sector thanks to transversal competences deriving from academic and industrial realities. European green deal and circular economy targets set by EU for 2025 are also related to the massive consumption of refractory materials in the steel industry. Operative lifetimes of refractories range from hours to several months depending on their role. As a result of increasingly tightened policies and disposal costs, and due to recent supply chain shortages, end-of-life refractories recovery and recycling practices are receiving great attention. Some of the core requirements for sustainability and circularity are the reduction of open-loop and down scaling strategies, to maintain refractory materials value as long as possible, of the end-of-life materials. Over the years application of numerical models has proved to be a useful strategy for researchers facing in-use issues related to refractory materials. In this study, different finite element models (FEM) applied to end-use refractories are discussed to understand their suitability for potential recyclability prediction. Thermomechanical characterization of prior- and post-use materials allow to identify the critical issues related to numerical models' development. The comparison between empirical results and the appropriate numerical model allow us to identify suitable pathways to improve refractories sustainability.

An investigation of the acid catalysed conversion of carbohydrates to platform chemicals

description: Methods to obtain useful chemicals derived from sources other than fossil fuels is particularly challenging. The chemical conversion of biomass, a carbohydrate rich feedstock, into useful liquid products has thus become an intensely researched field. In this study, catalysis mediated by various acid catalysts such as Lewis acids, mineral acids and heterogeneous acid resins were investigated for the conversion of fructose, glucose, sucrose, cellulose as well as microalgae into useful chemical products. High yields of products were obtained in the short-chained alcohol solvents, polar aprotic solvents as well as a biphasic system under various reaction conditions. The one-pot synthesis of n-alkyl levulinates and 5-alkoxymethylfurfural in high yields was obtained in short-chained primary alcohol solvents. The solid resin Amberlyst-15 at moderate temperatures and under atmospheric pressure catalysed these reactions. High yields (~80 mol% ) of combined products were obtained from fructose and sucrose with product selectivity dependent on acid concentration and time. Importantly, good yields of 50 mol% of combined products were obtained from glucose under these reaction conditions. Furthermore, microwave irradiation reduced the time required to obtain such products. The production of levoglucosenone (LGN) from the acid catalysed thermolysis of cellulose was investigated in various polar aprotic solvents. Of the solvents investigated, the acid catalysed conversion using mineral acids was the most successful in sulfolane. Levoglucosenone, a valuable chemical intermediate, which can undergo further reactions, was found to convert into 5-chloromethylfurfural with high isolated yields of 72 mol%. Likewise, under the same reaction conditions high combined yields of n-alkyl levulinates and 5-alkoxymethylfurfural from fructose, glucose and sucrose, of >80 mol% were obtained from LGN. In the final component of this study, whole microalga Nannochloropsis sp., was subjected to a one-pot biphasic system for the carbohydrate component conversion to 5 chloromethylfurfural (CMF) alongside lipid extraction. Good isolated yields of CMF (44 mol%) were obtained after 3 hours. Model compounds from both macroalgae and microalgae were also investigated in this study, however these were found to give significantly lower yields of CMF.

Palynology, taphonomy and geology of the early cretaceous Dinosaur Dreaming Fossil Site, Inverloch, Victoria, Australia

description: The recovery of vertebrate fossils from the Early Cretaceous Dinosaur Dreaming Fossil Site (DDFS), near Inverloch, Victoria, Australia, is restricted to an approximately 1 metre thick fluvial deposit, consisting of interbedded conglomerate and sandstone units that were deposited as part of a braided stream under high energy hyperconcentrated flow conditions. Palynological analyses of samples from this, at the time of deposition, high latitudinal site reveals a vegetation dominated by ferns, lycopods, gymnosperms and subordinate hepatics and mosses, indicative of microthermal (temperate to possible cool – temperate) settings. The palynology has also restricted the age of the site to 116.5 – 120 Ma (early to mid Late Aptian) in the upper part of the Cyclosporites hughesii Zone as defined by Partridge (2006). Comparison of the floral assemblage between sites affected and unaffected by periglacial structures has revealed only marginal differences, strongly suggesting little climatic variations during time of sediment deposition during this part of the Aptian. The DDFS lay at high latitudes in the Early Cretaceous, and there is evidence of climatic seasonality coupled with the time of onset of polar night conditions and the concomitant reduction in light availability observed in growth rings of arborescent taxa. Charcoal fragments attest to periodic wildfires brought about by the possible drying of the landscape. Homogenisation of cell walls in charcoal samples indicates that the fires occurred at temperatures ranging between 230°C to 340°C. Sedimentological evidence indicates that the skeletal elements accumulated in and around a lake environment prior to reworking. Bone modification and articulation patterns plus climatic settings support a subaerial exposure of skeletal material of several years. Partial sorting of light¬weight bone material is a result of hydraulic winnowing, most likely due to flooding resulting from heavy rain, prior to the reworking of the assemblage. The majority of bones were broken prior to mineralisation, implying trampling activity. However, only a few traces have been observed so far, suggesting that trampling occurred in sediments too fine grained to leave characteristic marks. Evidence of scavenging activity is restricted to marks on only a few bones. Disarticulated skeletal material was eventually reworked, transported and re-deposited following a high discharge hyperconcentrated flood event, with a short transport distance evidenced by the low degree of abrasion on outer bone surfaces. Weathering patterns of faunal elements do not show deterioration, which might be linked to cycles of freezing and thawing associated with periglacial environments. This is further corroborated by the flora which supports a microthermal (temperate to possible cool-temperate) setting.

description: Dirac materials are systems in which the dispersion is linear in the vicinity of the Dirac points. As a consequence of this linear dispersion, these systems exhibit unusual behavior and possess unique physical properties that are of great interest. In this work we utilize the single walled carbon nanotube (SWNT) as a model Dirac material and examine the system within the framework of Tomanaga-Luttinger Liquid theory (TLL) revealing several unconventional properties unique to these systems. Specifically, the exponents of the Green's function are electron density independent leading to electron density independent thermodynamic quantities and speed of sound; both of which are vastly different from traditional TLL behavior. Additionally, we discuss the implications the Virial Theorem has for this system; in particular, the total average ground state energy is given by $E=\mathcal{B}/r_s$ where $\mathcal{B}$ is a constant independent of $r_s$. Finally, experimental techniques are discussed in which these predictions of density independent exponents and their behavior can be verified.

description: We study dispersive mixed-order systems of pseudodifferential operators in the setting of $L^p$-Sobolev spaces. Under the weak condition of quasi-hyperbolicity, these operators generate a semigroup in the space of tempered distributions. However, if the basic space is a tuple of $L^p$-Sobolev spaces, a strongly continuous semigroup is in many cases only generated if $p=2$ or $n=1$. The results are applied to the linear thermoelastic plate equation inertial term and with Fourier's or Maxwell-Cattaneo's law of heat conduction.

description: A sufficiently strong long-range Coulomb interaction can induce excitonic pairing in gapless Dirac semimetals, which generates a finite gap and drives semimetal-insulator quantum phase transition. This phenomenon is in close analogy to dynamical chiral symmetry breaking in high energy physics. In most realistic Dirac semimetals, including suspended graphene, Coulomb interaction is too weak to open an excitonic gap. The Coulomb interaction plays a more important role at low energies in a two-dimensional semi-Dirac semimetal, in which the fermion spectrum is linear in one component of momenta and quadratic in the other, than a Dirac semimetal, and indeed leads to breakdown of Fermi liquid theory. We study dynamical excitonic gap generation in a two-dimensional semi-Dirac semimetal by solving the Dyson-Schwinger equation, and show that a moderately strong Coulomb interaction suffices to induce excitonic pairing. Additional short-range four-fermion coupling tends to promote excitonic pairing. Among the available semi-Dirac semimetals, we find that TiO$_{2}$/VO$_{2}$ nanostructure provides a promising candidate for the realization of excitonic insulator. We also apply the renormalziation group method to analyze the strong coupling between the massless semi-Dirac fermions and the quantum critical fluctuation of excitonic order parameter at the semimetal-insulator quantum critical point, and reveal non-Fermi liquid behaviors of semi-Dirac fermions.

description: Abstract.  Fundamental care combines the needs of the person being cared for with the caregiver’s actions. The approach is not just about addressing an individual’s physical needs but about understanding and addressing the psychosocial and relational needs of the person receiving care while providing support, generating trust, and associated appropriate actions and behaviours. It is a relationship process that takes place within the framework of an organisation with solid policies and systems that place the person at the centre of attention while enabling workers' job satisfaction. These fundamental needs are only met through a positive and trusting relationship with the care recipient, including their family and everyone involved. Abstracto. Los cuidados fundamentales combinan las necesidades de la persona atendida con las acciones de quien la cuida. No se trata solo de las necesidades físicas, sino que también comprenden las necesidades psicosociales y relacionales de la persona, respaldadas por la confianza y acciones adecuadas de los que la cuidan. El proceso se desarrolla en el marco de una organización que cuenta con políticas y sistemas sólidos que sitúan a la persona en el centro de la atención, mientras habilitan la satisfacción laboral de los trabajadores. Estas necesidades fundamentales sólo se satisfacen a través de una relación positiva y de confianza con la persona que recibe los cuidados, incluyendo a su familia y a todos los involucrados en el proceso.

description: Most, if not all, scalar-tensor theories are equivalent to General Relativity with a disformally coupled matter sector. In extra-dimensional theories such a coupling can be understood as a result of induction of the metric on a brane that matter is confined to. This article presents a first look at the non-Gaussianities in disformally coupled inflation, a simple two-field model that features a novel kinetic interaction. Cases with both canonical and Dirac-Born-Infeld (DBI) kinetic terms are taken into account, the latter motivated by the possible extra-dimensional origin of the disformality. The computations are carried out for the equilateral configuration in the slow-roll regime, wherein it is found that the non-Gaussianity is typically rather small and negative. This is despite the fact that the new kinetic interaction causes the perturbation modes to propagate with different sounds speeds, which may both significantly deviate from unity during inflation.

description: We study Josephson junctions with weak links consisting of two parallel disordered arms with magnetic properties -- ferromagnetic, half-metallic or normal with magnetic impurities. In the case of long links, the Josephson effect is dominated by mesoscopic fluctuations. In this regime, the system realises a $φ_0$ junction with sample-dependent $φ_0$ and critical current. Cooper pair splitting between the two arms plays a major role and leads to $2Φ_0$ periodicity of the current as a function of flux between the arms. We calculate the current and its flux and polarization dependence for the three types of magnetic links.

description: Στη διατριβή αυτή αναζητούμε περιοδικές τροχιές και οικογένειες αυτών, σε ισχυρά διαταραγμένα βαρυτικά συστήματα όπως αυτό των τριών σωμάτων, σε σώματα τυχαίας κατανομής μάζας, με περιστροφή γύρω από τους άξονές τους, με επίδραση από την πίεση της ηλιακής ακτινοβολίας και άλλες παρόμοιες διαταραχές. Η διδακτορική αυτή εργασία έχει ως βασικό σκοπό τη μελέτη σύνθετων δυναμικών συστημάτων όπως αυτό ενός αληθινού αστεροειδούς. Η εύρεση των περιοδικών τροχιών γίνεται όχι μόνο με κλασικές μεθόδους, όπως αυτή των διαφορικών προσεγγίσεων αλλά και με τη βοήθεια γενετικών-εξελικτικών αλγορίθμων ή μεθόδων ελαχιστοποίησης που προσομοιώνουν φυσικές διεργασίες. Συγκεκριμένα αναλύονται οι περιοδικές τροχιές γύρω από τον αστεροειδή 433-Έρωτα και το διπλό σύστημα του 65803-Δίδυμου-Δίμορφου. Αναπτύσσεται μια μέθοδος συνέχισης σχήματος από ένα απλό, αναλυτικό γεωμετρικό στερεό, όπως το τριαξονικό ελλειψοειδές, σε αυτό του ανομοιόμορφου αστεροειδούς αποτελούμενου από πλήθος σημειακών μαζών.
description: With this thesis we expect to find periodic orbits and their families, in severely disturbed gravitational systems such as the 3-body problem, with bodies of random mass distribution, with rotation around their axes, influenced by solar radiation pressure and other similar perturbations. This PhD aims to study such complex dynamical systems in real asteroids such as 433-Eros and the binary system of 65803-Didymos-Dimorphos. The search for periodic orbits is done not only via classical methods such as differential corrections, but also by using genetic-evolutionary algorithms or other minimization methods that simulate natural processes. The basic model used is a uniformly rotating triaxial ellipsoid which serves as a starting point before simulating the shape of the real asteroid (by using multiple point masses). A new method of shape transformation is introduced for this transition.

description: In dieser Arbeit wird die Entwicklung eines Algorithmus beschrieben, der es erlaubt, das zustandsselektierende Multireference-Configuration-Interaction (MRCI) Verfahren auf massiv-parallelen Rechnerarchitekturen zur Anwendung zu bringen. Das MRCI Verfahren zählt zu den Standardverfahren in der Quantenchemie. Es ist daher wünschenswert, die leistungsfähigsten heute verfügbaren Rechnerarchitekturen für MRCI-Rechnungen verwenden zu können. Der hier vorgestellte Algorithmus erfüllt die an ein paralleles Programm zu stellenden Anforderungen der Effizienz und Skalierbarkeit.Wir haben unser Programm angewendet zur Berechnung der Elektronenaffinitäten von O2, BO und NO, zur Berechnung der spektralen Eigenschaften von VF2 und VCl2 und zur Berechnung der Potentialenergieoberfläche von NO2. Weiterhin haben wir quantenchemische Berechnungen des einfachsten Mitglieds der Endiin-Familie durchgeführt.

description: In the process of analyzing an observed light curve, one often confronts various scenarios that can mimic the planetary signals causing difficulties in the accurate interpretation of the lens system. In this paper, we present the analysis of the microlensing event OGLE-2016-BLG-0733. The light curve of the event shows a long-term asymmetric perturbation that would appear to be due to a planet. From the detailed modeling of the lensing light curve, however, we find that the perturbation originates from the binarity of the source rather than the lens. This result demonstrates that binary sources with roughly equal-luminosity components can mimic long-term perturbations induced by planets with projected separations near the Einstein ring. The result also represents the importance of the consideration of various interpretations in planet-like perturbations and of high-cadence observations for ensuring the unambiguous detection of the planet.

Tuned and Non-Higgsable U(1)s in F-theory

description: We study the tuning of U(1) gauge fields in F-theory models on a base of general dimension. We construct a formula that computes the change in Weierstrass moduli when such a U(1) is tuned, based on the Morrison-Park form of a Weierstrass model with an additional rational section. Using this formula, we propose the form of "minimal tuning" on any base, which corresponds to the case where the decrease in the number of Weierstrass moduli is minimal. Applying this result, we discover some universal features of bases with non-Higgsable U(1)s. Mathematically, a generic elliptic fibration over such a base has additional rational sections. Physically, this condition implies the existence of U(1) gauge group in the low-energy supergravity theory after compactification that cannot be Higgsed away. In particular, we show that the elliptic Calabi-Yau manifold over such a base has a small number of complex structure moduli. We also suggest that non-Higgsable U(1)s can never appear on any toric bases. Finally, we construct the first example of a threefold base with non-Higgsable U(1)s.
