description: Due to their exceptional characteristics, nanomaterials are applied in multiple fields, including automotive, textiles or biomedical sectors, being Nanotechnology conceived as a Key Enabling Technology (KET). For this reason, the risks to health and environment posed by the special particularities of nanomaterial enabled products are critical to identify and control their associated hazards. Environmental research has focussed on elucidating and modelling of toxicokinetics and toxicodynamics of different types of nanomaterials in soil and aquatic organisms. In this regard, biofilms are considered as good bioindicators of contamination due to their ability to accumulate and react quickly to xenobiotics. Despite this, currently there is not any OECD validated protocol to study toxicokinetics and toxicodynamics of xenobiotics, and there is only one available study in the current literature where both parameters are analysed in these structures (Chaumet et al., 2019)
 The aim of this work was to set up the appropriate conditions to develop a protocol to study Multi-Component NanoMaterials (MCNMs) and High Aspect Ratio Nanoparticles (HARNs) tokicokinetics and toxicodynamics in biofilms. Pseudomonas putida, a Gram-negative bacterium that can be found in soils being involved in several relevant functions, was selected as model organism. Different conditions of temperature, surface material, incubation time etc. were tested in order to obtain significant biofilm biomass to perform toxicokinetic studies. Results showed that the incubation of bacterial cultures during 96 hours at 37°C, in polystyrene well plates coated with a polyelectrolyte lead to the highest amount of biofilm. For toxicodynamics studies, ROS production was selected as a parameter to be analysed using the CM-H2DCFDA dye. The appropriate experimental conditions were first set up with planktonic bacteria exposed to H2O2, and then applied in biofilms.
 This study has received funding from the European Union’s Horizon 2020 program (DIAGONAL, Grant Agreement no 953152). The DIAGONAL project aims to address existing gaps at risk assessment, risk management and risk governance levels providing new knowledge on multicomponent nanomaterials and high aspect ratio nanomaterials.

description: In this contribution, the limitations of the Carleman linearization approach are presented and discussed. The Carleman linearization transforms an ordinary nonlinear differential equation into an infinite system of linear differential equations. In order to transform the nonlinear differential equation, orthogonal polynomials which represent solutions of a Sturm–Liouville problem are used as basis. The determination of the time derivate of this basis yields an infinite dimensional linear system that depends on the considered nonlinear differential equation. The infinite linear system has the same properties as the nonlinear differential equation such as limit cycles or chaotic behavior. In general, the infinite dimensional linear system cannot be solved. Therefore, the infinite dimensional linear system has to be approximated by a finite dimensional linear system. Due to limitation of dimension the solution of the finite dimensional linear system does not represent the global behavior of the nonlinear differential equation. In fact, the accuracy of the approximation depends on the considered nonlinear system and the initial value. The idea of this contribution is to adapt the range of validity for the Carleman linearization in order to increase the accuracy of the approximation for different ranges of initial values. Instead of truncating the infinite dimensional system after a certain order a Taylor series approach is used to approximate the behavior of the nonlinear differential equation about different equilibrium points. Thus, the adapted finite linear system describes the local behavior of the solution of the nonlinear differential equation.
Multi-omic analysis of plasma-derived extracellular vesicles in breast cancer

Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Liquid biopsy is an emerging technology with potential to identify disease markers in patient breast cancer blood. Plasma contains abundant, biological nanoparticles called small extracellular vesicles (sEVs) which carry glycoconjugates (glycoproteins, glycolipids and proteoglycans). These glycoconjugates have been previously shown to change in breast cancer tissues and cell lines, making sEVs an appropriate liquid biopsy target to monitor glycosylation changes during disease and treatment. This thesis aimed to optimise a workflow for the multi-omic (proteomics and glycomics) analysis of plasma-derived sEVs from healthy individuals and breast cancer patient (before/after surgery). Three common isolation methods (ExoQuick, ultracentrifugation and size exclusion chromatography (SEC)) were compared to determine which method provides an enriched sEV population with minimal plasma protein contamination. The purity of isolated sEVs was assessed using nanoparticle tracking analysis and ‘omics analyses. The proteomics and Gene Ontology analysis of de-N-glycosylated peptides indicated that SEC-isolated sEVs contained the least non-sEV protein contamination, while glycomics analysis of N-glycans from sEV glycoproteins indicated that sEVs isolated using ExoQuick and ultracentrifugation showed great similarity to whole plasma glycosylation, indicating a high degree of plasma protein contamination compared with SEC. These findings form the basis for the further development of a multi-omic sEV analysis platform.

description: This paper discusses a field measurement method, based on a two-antenna setup, to qualify the transmission of transient signals inside a GTEM cell. The transmission characteristic of the GTEM1250 is evaluated by the Pearson correlation coefficient (PCC) and is presented with a heatmap. Due to deviations of the uncertainty contribution of the field homogeneity, the frequency band around 100 MHz is evaluated and its effect to the PCC is discussed. Therefore, a comparable narrowband transient signal, a damped sinusoidal (DS) is used. Furthermore, a detailed discussion focussing on nonlinear and distorting effects of the GTEM1250 is performed. The measurements in time domain (TD) identify comparable high secondary E-field components in the propagation direction, which are characteristic for higher order modes. Based on the same setup, another measurement is performed in frequency domain (FD) and relates the phase response of the GTEM cell to the above mentioned effects. According to the measured phase response the propagation time is discussed to investigate the distorting effects caused by higher order modes.
Universally optimal crossover designs under subject dropout

description: Subject dropout is very common in practical applications of crossover designs. However, there is very limited design literature taking this into account. Optimality results have not yet been well established due to the complexity of the problem. This paper establishes feasible, as well as necessary and sufficient conditions for a crossover design to be universally optimal in approximate design theory in the presence of subject dropout. These conditions are essentially linear equations with respect to proportions of all possible treatment sequences being applied to subjects and hence they can be easily solved. A general algorithm is proposed to derive exact designs which are shown to be efficient and robust.

description: The following paper introduces a novel scanning method for mapping and localization purposes in mobile robotics. Our method is based on a rotating monostatic radar network, which determines the positions of objects around the scanner via a continuously running lateration algorithm. The estimation of surfaces with ultrawideband radar networks has been studied experimentally in lab environments, especially with lateration, envelopes of spheres, and SEABED algorithms. But we do not see a link to the field of mapping and localization of mobile robots, where laser scanners are dominating. Indeed, only few research groups use radars for mapping and localization, but their applied sensor principle is based on a rotating focused radar beam. Consequently, only 2D radar scanners are known inside the robotic world and methods for 3D scanning with radars need to be investigated. This paper will derive the theoretical background of the sensor principle, which is based on a radar network on a rotating joint, and discuss its erroneous influences. We were performing first scans of standard geometries and deriving a model in order to compare theoretical and experimental measurement results. Furthermore, we present first mapping approaches and a simulation of a scanner with multiple sensors.

description: We fabricate a saturable absorber mirror by coating a graphene film on an output coupler mirror. This is then used to obtain Q-switched mode-locking from a diode pumped linear cavity waveguide laser inscribed in Ytterbium-doped Bismuthate Glass, with high slope and optical conversion efficiencies. The laser produces mode-locked pulses at 1039nm, with 1.5GHz repetition rate at an average 202mW output power. This performance is due to the combination of the graphene saturable absorber with the high quality laser glass.

description: In this paper, we present a method to increase the time resolution of a pulse width modulator by using delay lines. The modulator is part of an open loop class D power amplifier, which uses the ZePoC algorithm to code the audio signal which is amplified in the class D power stage. If the time resolution of the pulse width modulator is high enough, ZePoC could also be used to build an high accuracy AC power standard, because of its open loop property. With the presented method the time resolution theoretically could be increased by a factor of 16, which means here the time resolution will be enhanced from 5 ns to 312.5 ps.

description: Two solid phases of cyclohexane have been investigated over a temperature range spanning 13 to 266 K on a powdered, perdeuterated sample using neutron total scattering. Phase II has an ordered structure (C2/c) that forms below 186 K. Between 186 and 280 K it exists as a plastic solid - phase I (Fm3m), where the molecules are rotationally disordered about the lattice points of the face-centred cubic cell. Data-dependent atomistic configurations that represent the 'instantaneous' crystal structure have been generated from the total scattering data using Reverse Monte Carlo refinement. Analysis of local structure reveals that instantaneous distortions in phase I resemble the average structure of phase II.

description: The implicit graph conjecture states that every sufficiently small, hereditary graph class has a labeling scheme with a polynomial-time computable label decoder. We approach this conjecture by investigating classes of label decoders defined in terms of complexity classes such as P and EXP. For instance, GP denotes the class of graph classes that have a labeling scheme with a polynomial-time computable label decoder. Until now it was not even known whether GP is a strict subset of GR where R is the class of recursive languages. We show that this is indeed the case and reveal a strict hierarchy akin to classical complexity. We also show that classes such as GP can be characterized in terms of graph parameters. This could mean that certain algorithmic problems are feasible on every graph class in GP. Lastly, we define a more restrictive class of label decoders using first-order logic that already contains many natural graph classes such as forests and interval graphs. We give an alternative characterization of this class in terms of directed acyclic graphs. By showing that some small, hereditary graph class cannot be expressed with such label decoders a weaker form of the implicit graph conjecture could be disproven.

description: The direct interaction theory of electromagnetism, also known as Wheeler-Feynman electrodynamics, is often misinterpreted and found unappealing because of its reference to the absorber and, more importantly, to the so-called absorber condition. Here we remark that the absorber condition is indeed questionable and presumably not relevant for the explanation of irreversible radiation phenomena in our universe. What is relevant and deserves further scrutiny is the emergent effective description of a test particle in an environment. We therefore rephrase what we consider the relevant calculation by Wheeler and Feynman and comment on the status of the theory.

description: Transverse electromagnetic (TEM) waveguides are predominantly used for emission and immunity tests. General requirements for TEM waveguides are given by the IEC 61000-4-20. Annex C of the IEC 61000-4-20 specifies immunity tests based on high-altitude electromagnetic pulses with a double exponential waveform. This waveform's shape is sufficiently defined by the rise time and the pulsewidth. The quality of its transmission within a waveguide can, thus, be expressed by the allowed variation of these parameters. However, other arbitrary signals cannot be reduced to just these characteristic parameters. In this paper, a method is described that offers the possibility to characterize the transmission quality of a TEM cell for arbitrary transient waveforms. It is based on the Pearson correlation coefficient of a so-called reference signal and the signals being measured within the test volume of a TEM cell. Both signals are measured simultaneously with identical field probes in order to be independent from the reproducibility of the signal generator. The signals are windowed and limited to include only the defining reflections and distortions. By means of this signal-dedicated validation procedure, the transmission quality of a TEM waveguide can be validated for an arbitrary transient waveform.

description: In this work, we study liquid gallium stirring by rotating permanent magnets. We demonstrate possibility of easily creating different flow patterns by rotating permanent magnets, which can be industrially important for controlling heat and mass transfer processes in the system. Unlike the typical approach of simulating magnet rotation as a transient problem and time-averaging the Lorentz forces, we solve the magnet rotation as a harmonic (frequency domain) problem, which leads to forces equal to time-averaged ones and decreases the simulation time considerably. Numerical results are validated using qualitative flow structure results from the neutron radiography visualization of tracer particles and quantitative data from Ultrasound Doppler velocimetry.

The method analyzes the susceptibility of an electronic system with respect to intentional electromagnetic interferences and classifies the intentional electromagnetic environment (IEME). It extends the well-known statistical-based models fault tree analysis, electromagnetic topology and Bayesian networks (BN) with imprecise data, uncertainness with linguistic terms, and opinions of experts. In a final step, the critical scenarios and the elements and the location that contribute most to the risk are identified, which can be used to enhance the protection level.

description: Quantum control is an essential tool for the operation of quantum technologies such as quantum computers, simulators, and sensors. Although there are sophisticated theoretical tools for developing quantum control protocols, formulating optimal protocols while incorporating experimental conditions remains a challenge. In this paper, motivated by recent advances in realization of real-time feedback control in circuit quantum electrodynamics systems, we study the effect of experimental imperfections on the optimality of qubit purification protocols. Specifically, we find that the optimal control solutions in the presence of detector inefficiency and non-negligible decoherence can be significantly different from the known solutions to idealized dynamical models. In addition, we present a simplified form of the verification theorem to examine the global optimality of a control protocol.

description: The complexity of modern systems on the one hand and the rising threat of intentional electromagnetic interference (IEMI) on the other hand increase the necessity for systematical risk analysis. Most of the problems can not be treated deterministically since slight changes in the configuration (source, position, polarization, ...) can dramatically change the outcome of an event. For that purpose, methods known from probabilistic risk analysis can be applied. One of the most common approaches is the fault tree analysis (FTA). The FTA is used to determine the system failure probability and also the main contributors to its failure. In this paper the fault tree analysis is introduced and a possible application of that method is shown using a small computer network as an example. The constraints of this methods are explained and conclusions for further research are drawn.

description: Im Ägyptischen Museum der Universität Bonn werden weltweit einmalige Objekte eines altägyptischen Bronzegussateliers aufbewahrt. Sie stammen von der Qubbet elHawa, einem Felsgräberberg gegenüber der modernen Stadt Assuan und wurden dort im Jahr 1969 von Bonner Ägyptologen unter Elmar Edel in Grab QH 207 entdeckt.
Das Grab datiert an das Ende des Alten Reiches (2347-2216 v. Chr.) und wurde in der ägyptischen Spätzeit (664-332 v. Chr.) für Bestattungen einer lokalen Priesterfamilie von der Nilinsel Elephantine wiederbenutzt. Die genannten
Artefakte stammen aus dem Kontext der jüngsten Bestattung (»Bestattung 1«), ihre genaue Lage ist damals jedoch nicht dokumentiert worden. Dennoch bieten eben diese Artefakte Ägyptologen, Restauratoren und Naturwissenschaftlern
zum ersten Mal die Möglichkeit, die Bronzegusstechnologie der Spätzeit mithilfe eines breiten Spektrums moderner Analysemethoden zu erforschen.

from modern Aswan. They were discovered in 1969 by members of the Bonn excavation team under Elmar Edel in tomb QH 207. This tomb dates back to the end of the Old Kingdom (2347-2216 BC). It was reused during the Late Period (664-332 BC) for several burials of members of the local Elephantine priesthood. The aforementioned artifacts belong to the latest burial (»Bestattung 1«), but their specific archaeological context has not been recorded in detail. Nevertheless, they enable Egyptologists, conservators and natural scientists alike to thoroughly study the technology of Bronze casting in the Late Period for the first time using a wide range of modern methods of analysis.

description: In this paper, firstly we study some left invariant Riemannian metrics on para-hypercomplex 4-dimensional Lie groups. In each Lie group, the Levi-Civita connection and sectional curvature have been given explicitly. We also show these spaces have constant negative scalar curvatures. Then by using left invariant Riemannian metrics introduced in the first part, we construct some left invariant Randers metrics of Berwald type. The explicit formulas for computing flag curvature have been obtained in all cases. Some of these Finsler Lie groups are of non-positive flag curvature.

description: Low temperature high magnetic field $^{57}Fe$ M$\ddot{o}$ssbauer measurements were carried out on inter-metallic $Hf_{0.77}Ta_{0.23}Fe_2$ compound by following novel paths in H-T space. The ferromagnetic (FM) fraction at 5K and zero magnetic field is shown to depend on cooling field i.e., higher the field higher is the FM fraction. M$\ddot{o}$ssbauer spectra collected in the presence of 4 Tesla magnetic field shows that the antiferromagnetic (AFM) spins cant with respect to the applied magnetic field and hence, contribute to the total bulk magnetization in this compound. The data also show induced magnetic moment even at the 2a site of AFM phase. M$\ddot{o}$ssbauer spectra collected using CHUF (cooling and heating in un-equal magnetic fields) protocol shows re-entrant transition when sample is cooled in zero field and measured during warming in 4 Tesla showing FM state as the equilibrium state.

description: This article adresses the model reduction of IC conducted emission models. A method to efficiently deal with the high number of independent sources in IC conducted emission models, which are a strong limitation for model order reduction, is presented. A network alteration is proposed, which allows for a much higher model reduction than standard approaches. The system of the altered network can be more efficiently reduced with standard model order reduction algorithms in order to speed up frequency-simulations. Synthesising the reduced system into a passive electrical network enables fast time-simulations to be made with circuit simulators. The whole procedure is validated by reducing an example of an IC conducted emission model of an 32 Bit microcontroller.

description: We report on the valence fluctuation of Ce in CeMo$_{2}$Si$_{2}$C as studied by means of magnetic susceptibility $χ(T)$, specific heat $C(T)$, electrical resistivity $ρ(T)$ and x-ray absorption spectroscopy. Powder x-ray diffraction revealed that CeMo$_{2}$Si$_{2}$C crystallizes in CeCr$_{2}$Si$_{2}$C-type layered tetragonal crystal structure (space group \textit{P4/mmm}). The unit cell volume of CeMo$_{2}$Si$_{2}$C deviates from the expected lanthanide contraction, indicating non-trivalent state of Ce ions in this compound. The observed weak temperature dependence of the magnetic susceptibility and its low value indicate that Ce ions are in valence fluctuating state. The formal $L_{III}$ Ce valence in CeMo$_{2}$Si$_{2}$C $$ = 3.11 as determined from x-ray absorption spectroscopy measurement is well bellow the value $ \simeq$ 3.4 in tetravalent Ce compound CeO$_{2}$. The temperature dependence of specific heat does not show any anomaly down to 1.8 K which rules out any magnetic ordering in the system. The Sommerfeld coefficient obtained from the specific heat data is $γ$ = 23.4 mJ/mol\,K$^{2}$. The electrical resistivity follows the $T{^2}$ behavior in the low temperature range below 35 K confirming a Fermi liquid behavior. Accordingly both the Kadowaki Wood ratio $A/γ^{2}$ and the Sommerfeld Wilson ratio $χ(0)/γ$ are in the range expected for Fermi-liquid systems. In order to get some information on the electronic states, we calculated the band structure within the density functional theory, eventhough this approach is not able to treat 4f electrons accurately. The non-$f$ electron states crossing the Fermi level have mostly Mo 4d character. They provide the states with which the 4f sates are strongly hybridized, leading to the intermediate valent state.

description: Abstract

Mango fruit export is significantly hindered by quarantine pests. Fruit fly, being a devastating quarantine pest need disinfectant treatments such as postharvest quarantine heat treatments (PQHT); hot water treatment (HWT) and vapour heat treatment (VHT) for export to high value markets. We reported for the first time, effects of HWT and VHT on fruit quality of two novel and emerging Pakistani mango cultivars ‘Azeem Chaunsa’ and ‘Chenab Gold’ after fruit harvest. For this purpose, an integrated study was executed to investigate the effects of HWT & VHT treatment on fruit quality of ‘Chenab Gold’ and ‘Azeem Chaunsa’ under simulated air conditions (Temp. 28±2 ºC; RH 60-65%) till fruit ripening in two independent experiments. Irrespective to days at shelf, VHT-treated mango fruit exhibited significant lower fruit weight loss, respiration rate and retained significantly higher fruit vitamin-c contents and sensory attributes in both commercial mango cultivars as compared to untreated and HWT-treated fruit. Moreover, significant improved fruit total phenolic contents (TPC), anti-oxidative activity and activity of catalase (CAT) enzyme were observed in VHT-treated fruit for both ‘Azeem Chaunsa’ and ‘Chenab Gold’ mango fruit during the entire fruit ripening at shelf. However, with progress in days at shelf, both VHT and HWT enhanced the fruit ripening as evident by higher fruit total soluble solid (TSS), sugar acid ratio, lowest fruit firmness and developed more peel colour development as compared to untreated fruit. So, it can be concluded that VHT treatment is more efficient PQHT for ‘Chenab Gold’ and ‘Azeem Chaunsa’ than HWT and can be employed as disinfectant treatment without compromising fruit physiological, anti-oxidative and sensory quality losses during simulated air shipments.

description: Up to now most limits for radiated emission are given as values for the electrical field strength. Battermann, 2007 has shown that the frequency range extension for radiated emission measurements above 1 GHz generates a lot of problems while performing the test on a classical test site as depicted in Fig. 1. This paper will give a motivation to use an other measurand namely the total-radiated-power than electrical field strength by using alternative test sites like reverberation chambers, TEM-waveguides, Fully Anechoic Rooms (FAR) etc. Nevertheless most of the existing standards still specify electrical field strength limits. This paper will show how to set the parameters in the given algorithm to establish a link between measured total radiated power and equivalent electrical field values.

description: This paper addresses issues related to the order reduction of systems with multiple input/output ports. The order reduction is divided up into two steps. The first step is the standard order reduction method based on the multipoint approximation of system matrices by applying Krylov subspace. The second step is based on the rejection of the weak part of a system. To recognise the weak system part, Lyapunov equations are used. Thus, this paper introduces efficient solutions of the Lyapunov equations for port to port subsystems.

SO(10) GUT in Four and Five Dimensions: A Review

description: We review SO(10) grand unified theories (GUTs) in four and five dimensions (4D and 5D). The renormalizable minimal SO(10) SUSY GUT is the central theme of this review. It is very predictive and makes it possible to construct all mass matrices including those of the Dirac and heavy right-handed Majorana neutrinos. So it is not only able to reproduce all the low energy data, except for too larger $θ_{13}$ in the lepton mixing angles (which can be evaded without spoiling the basic ingredients), but also predicts almost all new physics beyond the standard model (SM) like neutrinoless double beta decay, the electric and magnetic dipole moments of the quark-lepton, lepton flavour violation, leptogenesis etc. To be very predictive, on the other hand, implies that predictions are unambiguous and they are always exposed to severe compatibilities with observations as well as to a conceptual consistency check. The explicit construction of the Higgs superpotential and the explicit display of a symmetry breaking pattern from GUT to the SM show that the naive desert from the SM to GUT in the minimal supersymmetric standard model (MSSM) is a too simplified concept and we have many definitely determined intermediate energy scales in general.

description: Excerpts from the report: For many years the U.S. Department of Agriculture (USDA) has been helping private-land owners restore their surface-mined land as part of their regular programs of wise land use and conservation treatment. USDA also has done restoration work and research studies on the public land it administers. Its experience and skills range all the way from preplanning mining to prevent offsite damage to development of a mined area for highly intensive uses. Through studies and experience and through participation in the 2-year National Surface Mine Study under Public Law 89-4, USDA has gathered a great deal of information about surface-mined land conservation progress and needs. In this report highlights of the data are given as well as ideas for future action, suggested by research and experience, that can speed restoration of the surface-mined-land that is intermingled with farm, ranch, forest, and other land in rural and suburban America.
