description: YouSound is a social science research project that studies symphonic music education organizations centred on the inclusion of minor migrants and refugees in Europe – www.yousound.eu We have chosen two organisations in different countries to serve as case studies: the Dream Orchestra in Sweden, and El Sistema Greece. In 2022 and 2023, we are visiting both countries, applying ethnographic methods to better grasp the complexity of interactions between multicultural human beings in these music neducation contexts. Welcome to the fourth and final YouSound Zine! The two first issues were focused on the Dream Orchestra in Gothenburg, Sweden; the two final zines are about our ethnographic experience at El Sistema Greece in Athens. Beatriz Machado, the team’s ethnographic illustrator, has spent a month and a half observing music classes in multicultural neighbourhoods and at the Schisto Refugee Camp.\r\n\r\nIllustrating such complex and volatile realities has proven to be demanding for the eye that tries to see beyond the obvious and for the hand that tries to picture the subtleties of interactions. Clearly, such illustrations are subjective, even personal.\r\nFor these zines, I have asked Beatriz to accompany her drawings with her own words, making it a sort of ethnographic diary, in the hope that these two methods of communication – drawings and words – may be complementary and inclusive. Such a mix is risky: words might close off what could be left open by the drawn lines; illustrations might fix what could be more poetic between the written lines. YouSound Zines aim at being inclusive, stretching the communication tools of the social sciences through artistic ways of seeing and expressing. When paying attention to the illustrations in the four fanzines, questions are raised. Each interrogation is nurtured by what is seen and by who sees, when and from where. Such attention to relativism, in its question form, may serve as a good basis to begin analysing the intricacies of what is being done by Dream Orchestra, by El Sistema Greece, and by the YouSound Research Project too, by taking a reflexive perspective. We wish to thank all those who have engaged with us in both countries for opening our minds to new questions, to the pragmatism they practise daily for survival, and to social complexity.

description: We describe an algorithm for obtaining generators of the unit group of the integral group ring ZG of a finite abelian group G. We used our implementation in Magma of this algorithm to compute the unit groups of ZG for G of order up to 110. In particular for those cases we obtained the index of the group of Hoechsmann units in the full unit group. At the end of the paper we describe an algorithm for the more general problem of finding generators of an arithmetic group corresponding to a diagonalizable algebraic group.

description: Complex gene networks regulated by master control genes are critical for the coordination of fundamental molecular and cellular processes in metazoans. Their misfunction might cause severe diseases like cancer. In this thesis, two evolutionary highly conserved master control genes, namely p53 and Myc, have been comprehensively analyzed in the simple metazoan model system Trichoplax adhaerens (phylum Placozoa). Additionally, the newly described species, Polyplacotoma mediterranea, will provide further promising possibilities for functional and comparative studies. The tumor suppressor p53 is well known for the regulation of programmed cell death (apoptosis), but also controls the cell metabolism and cell cycle. In this work, functional and comparative genetic studies on the p53 homolog tap53 have been performed in T. adhaerens. The in vivo accumulation of tap53 by inhibiting the tap53-taMdm2 interaction as well as the tap53 knockdown resulted in a significant increase of apoptotic cells and an increased mortality. Furthermore, multiple tap53 interaction partners identified by transcriptomic analyses after tap53 knockdown suggest the existence of an alternative and tap53-independent apoptosis signaling pathway. Genes belonging to the innate immune system and the cellular stress response were likewise found differentially expressed in response to tap53 knockdown. These results suggest that tap53 fulfills multiple crucial functions in Trichoplax and is essential for the survival of the organism. As transcription factors, Myc and its most important interaction partner Max regulate cellular processes and mechanisms such as differentiation, proliferation and the cell cycle. The biochemical studies carried out in the course of this thesis on the full-length proteins taMyc and taMax of T. adhaerens provided first insight on their protein structure and interaction. Using different methods, dimerization of full-length proteins was demonstrated which is a prerequisite for functional DNA binding capabilities. This suggests that taMyc and taMax play an essential role as transcription factors in Trichoplax and support an evolutionary conserved function throughout metazoans. This thesis provides new important insights on the function and characteristics of p53 and Myc/Max regulatory networks in a simple metazoan and is the base for future applied medical research on cellular regulation processes.

description: Marginally outer trapped surfaces (MOTSs) are the main tool in numerical relativity to infer properties of black holes in simulations of highly dynamical systems. On the one hand, the present work extends previous numerical methods in order to allow tracking of highly distorted horizons in axisymmetry. On the other hand, by applying the new method to a family of initial data as well as to simulations of head-on collisions of black holes, we discover three new phenomena: (i) the merger of MOTSs providing a connected history of the full merger in terms of marginal surfaces without any "jumps", (ii) the formation of self-intersecting MOTSs immediately after the merger, and (iii) a non-monotonicity result for the area of certain smoothly evolving MOTSs. The merger of MOTSs closes a gap in our understanding of binary-black-hole mergers in terms of the quasilocal horizon framework and provides the quasilocal analog of the famous "pair-of-pants" picture of the event horizon of two merging black holes. It allows tracking the evolution of properties such as the area through the highly dynamical regimes from the initially separate to the final common horizon. Through a detailed analysis of geometrical and dynamical properties, we uncover features of the horizons not often considered. In particular, we show why the area increase law for smoothly evolving MOTSs fails to hold in some of the cases analyzed here. Furthermore, we demonstrate a surprisingly direct correspondence of the decay behavior of multipoles and the shear on the outermost horizon with the quasinormal modes of a Schwarzschild black hole. An important role is played by the spectrum of the MOTS stability operator, for which we provide numerical examples of the connection between invertibility of the operator and the existence of a MOTS. Furthermore, we give a prospect of how the full spectrum can become useful for gaining more insight into the merger in absence of symmetries. Finally, a first working generalization of the new numerical algorithm to non-axisymmetric situations is shown, proving the general applicability of the method.

description: Nowadays, the extraction of buildings from aerial imagery is mainly done through deep convolutional neural networks (DCNNs). Buildings are predicted as binary pixel masks and then regularized to polygons. Restricted by nearby occlusions (such as trees), building eaves, and sometimes imperfect imagery data, these results can hardly be used to generate detailed building footprints comparable to authoritative data. Therefore, most products can only be used for mapping at smaller map scale. The level of detail that should be retained is normally determined by the scale parameter in the regularization algorithm. However, this scale information has been already defined in cartography. From existing maps of different scales, neural network can be used to learn such scale information implicitly. The network can perform generalization directly on the mask output and generate multi-scale building maps at once. In this work, a pipeline method is proposed, which can generate multi-scale building maps from aerial imagery directly. We used a land cover classification model to provide the building blobs. With the models pre-trained for cartographic building generalization, blobs were generalized to three target map scales, 1:10,000, 1:15,000, and 1:25,000. After post-processing with vectorization and regularization, multi-scale building maps were generated and then compared with existing authoritative building data qualitatively and quantitatively. In addition, change detection was performed and suggestions for unmapped buildings could be provided at a desired map scale. . © 2020 International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences - ISPRS Archives.

description: Topological insulators (TIs) are a novel class of materials with nontrivial surface or edge states. Time-reversal symmetry (TRS) protected TIs are characterized by the Z2 topological invariant and their helical property becomes lost in an applied magnetic field. Currently there exist extensive efforts searching for TIs that are protected by symmetries other than TRS. Here we show, a topological phase characterized by a spin Chern topological invariant is realized in an inverted electron-hole bilayer engineered from indium arsenide-gallium antimonide (InAs/GaSb) semiconductors which retains robust helical edges under a strong magnetic field. Wide conductance plateaus of 2e2/h value are observed; they persist to 12T applied in-plane magnetic field without evidence for transition to a trivial insulator. In a perpendicular magnetic field up to 8T, there exists no signature to the bulk gap closing. While the Fermi energy remains inside the bulk gap, the longitudinal conductance increases from 2e2/h in strong magnetic fields suggesting a trend towards chiral edge transport. Our findings are first evidences for a quantum spin Hall (QSH) insulator protected by a spin Chern invariant. These results demonstrate that InAs/GaSb bilayers are a novel system for engineering the robust helical edge channels much needed for spintronics and for creating and manipulating Majorana particles in solid state.

description: Mithilfe der Magnetresonanztomographie (MRT) werden Schichtbilder der Patientenanatomie aufgenommen. Grundlage hierfür ist die Wechselwirkung zwischen den Wasserstoffprotonen im Gewebe und der elektromagnetischen Umgebung im MRT-Scanner. Da die Schichtbilder über einen sehr hohen Weichgewebekontrast verfügen und darüber hinaus in beliebigen Orientierungen aufgenommen werden können, ist diese Bildgebung auch zunehmend interessant als visuelle Unterstützung von minimal-invasiven Interventionen. Ein solcher Einsatz setzt hohe Anforderungen an Instrumente und Gerate, die in der elektromagnetischen Umgebung des MR-Scanners verwendet werden. Tabelle 1 zeigt eine Übersicht der vorherrschenden elektromagnetischen Felder. Die Instrumente und Gerate müssen einerseits in einer solchen Umgebung ihre Funktionserfüllung gewährleisten und dürfen andererseits kein Risiko für den Patienten und den interventionellen Radiologen darstellen. Zur Kategorisierung der Eignung werden in der Normenreihen EN 60601 folgende Kompatibilitätsstufen definiert: MR safe, MR conditional und MR unsafe. Diese beziehen sich jedoch lediglich auf den diagnostischen Einsatz und sollen hierfür die Patientensicherheit gewährleisten. Wahrend operativer Eingriffe unter MRT-Führung ist es darüber hinaus erforderlich, dass die Interventionsprozedur nicht durch die Verwendung der Gerate negativ beeinflusst wird. Ziel dieses Beitrages ist es daher, ein Sicherheitskonzept vorzustellen, welches neben der Patientensicherheit auch die sogenannte Behandlungssicherheit berücksichtigt.

description: The objective of this work is to study the effect that the addition of magnetic nanoparticles to a natural ester has on its properties and its cooling capacity. Some samples of ferrofluid (natural ester with maghemite) have been prepared using different concentrations. These have been characterized by measuring their thermo-hydraulic and dielectric properties, to find an optimal concentration. Then, the cooling capacities of the optimal nanofluid and the base fluid have been tested in a transformer immersed in these liquids. The experimental platform allowed the measurement of temperatures in different locations at different load levels. Parallel simulations of these tests have been carried out with a Computational Fluid Dynamics model of the experimental platform. The results show an improvement of the insulating capacity of the base fluid with the addition of maghemite nanoparticles, and an enhanced cooling capacity. .

Physiological responses to waterlogging in barley (Hordeum vulgare L.)
Creators: name: Pang, Jiayin
Publisher: name: University Of Tasmania
Year: 2023

description: Waterlogging is a major environmental constraint severely limiting crop production both in Australia and worldwide. In Australia, the problem is especially acute in higher rainfall areas with poorly draining soils. With most Australian commercial barley cultivars being waterlogging sensitive, waterlogging tolerant genetic material has to be selected and used in the breeding programs. Of specific interest is Chinese germplasm collection. However, lack of appropriate screening methodology makes selection ofwaterlogging tolerant cultivars difficult. Also, waterlogging is a complex abiotic stress encoding a large number of physiological and biochemical mechanisms and complicated by many confounding factors. Accordingly, the aims of this project were three-fold: (1) to develop an efficient screening methodology for waterlogging tolerance in barley breeding programs; (2) to select some waterlogging tolerant cultivars among existing barley germplasm; and (3) to understand the physiological, morphological and anatomical mechanisms encoding waterlogging tolerance in barley. The project was an integral part ofGRDC-funded collaboration between Australia and China on barley genetics. Barley plant growth was adversely affected by waterlogging. As waterlogging stress developed, chlorophyll content, net C02 assimilation and maximal photochemical efficiency of PSil (Fv/Fm) decreased significantly. Among these, chlorophyll fluorescence of dark-adapted samples (Fv/Fm values) was found to be the most efficient screening parameter for large-scale programs for waterlogging tolerance. Among studied genotypes, the Chinese cultivar TX9425 was found to be the most waterlogging tolerant, with the least reduction of plant growth, chlorophyll content, chlorophyll fluorescence and photosynthetic parameters. Naso Nijo (a Japanese cultivar) and Franklin (an Australian cultivar) were found to be the most susceptible to waterlogging. The adverse effects in stressed plants were alleviated following 2 weeks recovery in all cultivars. These contrasting genotypes were used later in all physiological studies. Overall, this study suggests that substantial genetic potential exists to improve waterlogging tolerance in barley. Measuring chlorophyll fluorescence of darkadapted samples (Fv/Fm values) is recommended as an efficient screening tool for waterlogging tolerance in barley breeding program. Key features targeted by breeding should include both morphological (production of more adventitious roots and formation of larger aerenchyma area in adventitious roots) and physiological (high ability of 0 2 uptake and K+ acquisition in plant roots) traits, as well as the plant's ability to withstand soil-borne phytotoxins. Foliar application of nutrient c~ be used in practice to alleviate the adverse effects ofwaterlogging.

description: Die moderne biopharmazeutische Industrie beschäftigt sich mit der Herstellung von Wirkstoffen, die in Bioprozessen produziert werden. Ein breites Anwendungsgebiet haben Biopharmaka, zu denen Impfstoffe, therapeutische Proteine und biologische Moleküle gehören. Säugetierzellen bilden eine wichtige Gruppe der Wirtszellen in der Bioproduktion. Der Zellkultivierungsprozess der Säugetierzellen ist komplexer als andere Grundoperationen (Engl. unit operations), daher sind hierbei umfangreiche Prozessüberwachung und -kontrolle notwendig, um eine hohe Qualität und Sicherheit der Biopharmaka zu gewährleisten. Im Rahmen der PAT-Initiative (Engl. Process Analytical Technology) setzen sich die biopharmazeutische Industrie und die regulatorischen Behörden dafür ein, dass der Bioprozess genauer überwacht und verstanden wird. Auf Basis von Multivariate Datenanalyse (MVDA) und Sensorik mit modernen Prozessanalysetechniken, zwei PAT-Elemente, stellt die Methode der Spektroskopie zur Bioprozessüberwachung als geeignet dar. Die Arbeit behandelt die Evaluierung der MIR-, 2DF- und UV/VIS-Spektroskopie zur Überwachung eines Zellkultivierungsprozesses mit CHO-Zellen. Methoden aus der MVDA wurden stets verwendet. In erstem Teil der Arbeit wurde mit Hilfe der MIR- und 2DF- Spektroskopie fünf CPPs (Engl. critical process parameters) untersucht: Glucose-, Laktat- und Glutamin-Konzentrationen, sowie Gesamtzellzahl und Lebendzellzahl. Es konnte gezeigt werden, dass die beiden spektroskopischen Methoden parallel zu einander verschiedene Zielanalyten simultan detektieren können. In zweitem Teil der Arbeit wurde eine Methode zur gezielten Induktion von Apoptose in CHO-Zellen entwickelt. Es konnten mit der Methode Zellkulturen mit verschiedenem Anteil apoptotischer Zellen generiert werden. Die induzierte Apoptose wurde als ein neuer Prozessparameter im letzten Teil der Arbeit eingeführt. Die 2DF- und UV/VIS-Spektroskopie diente hierbei erfolgreich der Überwachung, um den Anteil apoptotischer Zellen sowie die Gesamtzellzahl im Bioreaktor zu detektieren.

This new environment was tested in six tenth-grade chemistry classes (upper secondary) taught by five different teachers in three different schools over the course of five months and evaluated for effectiveness. Students completed knowledge tests before and after they used the AR learning environment to test their learning gain, and surveys to measure their acceptance of the technology, the cognitive load they experienced, and their attitude toward the use of AR to learn the mechanism for radical substitution. Analysis shows that the knowledge posttest scores were significantly higher than the pretest scores (p < 0.001), with a large effect size (r = 0.8). Student responses showed acceptance of the technology, experience of low extraneous cognitive load, and a positive attitude toward the use of AR to learn this reaction mechanism. These findings indicate that this AR learning environment can be used to teach the mechanism of radical substitution to tenth-grade students in introductory high school chemistry courses.

description: This paper is a sequel to arXiv:1108.0967. We further study Gromov-Hausdorff collapsing limits of Ricci-flat Kähler metrics on abelian fibered Calabi-Yau manifolds. Firstly, we show that in the same setup as arXiv:1108.0967, if the dimension of the base manifold is one, the limit metric space is homeomorphic to the base manifold. Secondly, if the fibered Calabi-Yau manifolds are Lagrangian fibrations of holomorphic symplectic manifolds, the metrics on the regular parts of the limits are special Kähler metrics. By combining these two results, we extend arXiv:math/0008018 to any fibered projective K3 surface without any assumption on the type of singular fibers.

description: In order to increase availability in a distributed system some or all of the data items are replicated and stored at separate sites. This is an issue of key concern especially since there is such a proliferation of wireless technologies and mobile users. However, the concurrent processing of transactions at separate sites can generate inconsistencies in the stored information. We have built a distributed service that manages updates to widely deployed counter-like replicas. There are many heavy-weight distributed systems targeting large information critical applications. Our system is intentionally, relatively lightweight and useful for the somewhat reduced information critical applications. The service is built on our distributed concurrency control scheme which combines optimism and pessimism in the processing of transactions. The service allows a transaction to be processed immediately (optimistically) at any individual replica as long as the transaction satisfies a cost bound. All transactions are also processed in a concurrent pessimistic manner to ensure mutual consistency.

description: Der Einsatz von Pulswechselrichtern in modernen Kraftfahrzeugen stellt für die EMV-Fachabteilungen der OEMs eine besondere Herausforderung dar. Im Gegensatz zum Industriebereich erschwert der wesentlich eingeschränktere Bauraum eine günstige EMV-Auslegung von drehzahlveränderlichen elektrischen Antriebssystemen im automobilen Umfeld. Darüber hinaus gelten deutlich strengere Grenzwertanforderungen, um die hochkomplexe Bordelektronik vor elektromagnetischen Interferenzen zu schützen und einen kundentauglichen Empfang von analogen und digitalen Funkdiensten zu gewährleisten. EMV-Betrachtungen von HV-Systemen in elektrifizierten Fahrzeugen sind mittlerweile fester Bestandteil wissenschaftlicher Konferenzen. Dennoch ist auffällig, dass sich vergleichsweise wenige Publikationen auf die Gesamtfahrzeugebene beziehen. Mögliche Gründe hierfür sind die deutlich höheren Kosten für Messvorhaben und die Geheimhaltungspolitik der OEMs für aktuelle Fahrzeugprojekte. Um Forschungen auf dieser Ebene zu ermöglichen, wurde im Rahmen des EU-Förderprojektes EM4EM ein elektrifizierter Fahrzeugdemonstrator mit seriennahen HV-Komponenten aufgebaut. Der Beitrag thematisiert Netzwerkmodelle zur Beschreibung und Einordnung charakteristischer Störgrößen auf dem Traktionsund Phasennetz automobiler HV-Systeme. Im Rahmen von leitungsgebundenen Zeitbereichsmessungen eines Forschungsdemonstrators werden sie für verschiedene Betriebszustände validiert. Die dafür verwendeten HV-Adapter ermöglichen hochohmige Spannungsmessungen mit differentiellen Tastköpfen und induktive Strommessungen für den geschirmten und ungeschirmten Teil der HV-Leitungen.

description: We have examined the singlet excitons in two representatives of acene-type (tetracene and pentacene) and phenacene-type (chrysene and picene) molecular crystals, respectively, using electron energy-loss spectroscopy at low temperatures. We show that the excitation spectra of the two hydrocarbon families significantly differ. Moreover, close inspection of the data indicates that there is an increasing importance of charge-transfer excitons at lowest excitation energy with increasing length of the molecules.

description: Die zunehmende Integration von leitungselektronischen Komponenten in Elektround Hybridfahrzeugen hat einen großen Einfluss auf die elektromagnetische Verträglichkeit (EMV) im Fahrzeugbereich. Die elektrischen Antriebssysteme mit Leistungen im 100kWBereich werden aus Gründen der Energieeffizienz bei aktuellen Fahrzeugen mit LithiumIonen Batterien mit hohen Gleichspannungen [1] betrieben. Der Antriebsumrichter erzeugt an seinen Ausgangsklemmen ein frequenzvariables gepulstes Drehstromsystem, mit dem entweder ein Asynchronmotor oder ein permanent erregter Synchronmotor betrieben wird. Um den Wirkungsgrad des Antriebssystems weiter zu steigern, werden im Antriebsumrichter möglichst schnell schaltende IGBTs [2] eingesetzt. Allerdings verursachen diese schnellen Schalthandlungen im Umrichter breitbandige Störaussendungen, die in andere Teile des Bordnetzes überkoppeln können. Im Vergleich zur klassischen Fahrzeug-EMV, die das 12V Bordnetz beinhaltet, sind die im Antriebsbordnetz entstehenden Störaussendungen wesentlich höher. Um diesen neuen Gegebenheiten zu begegnen, werden aktuell alle EMV Standards im Fahrzeugbereich um die neuen Antriebsstrangkomponenten ergänzt. Bezüglich des Antriebsstrangs werden in der aktuellen Version der CISPR 25 [3] Komponententests mit dem Antriebssystem beschrieben. Hierbei wird der Umrichter, der im Wesentlichen die Störquelle darstellt, in der Schirmkabine platziert. Um den Umrichter für Messungen sowohl der leitungsgebundenen Störaussendung auf der Antriebs-, wie der Batterieleitung als auch der gestrahlten Störaussendung betreiben zu können, muss er zum einen über eine Gleichspannungsquelle versorgt werden und zum anderen an seinen Motorklemmen eine Last also einen Antrieb antreiben können. Aktuell wird nach CISPR 25 ein realer Antrieb an den zu testenden Umrichter angeschlossen. Um den Umrichter in realitätsnahen Betriebspunkten betrieben zu können, wird die Welle des Antriebs aus der Halle geführt, um dort eine mechanische Belastungsmaschine (in der Regel ein zweiter leistungselektronisch geregelten Antrieb) anzuschließen. Um die Schirmwirkung der Halle nicht zu beeinträchtigen und die Lastmaschine zu entkoppeln wird die Welle entweder isoliert (Kunststoffwelle) oder über eine Wellenfilterung (Wellenschirmung) aus der Halle geführt, was zumindest bei einer bestehenden Halle problematisch ist. Da der Antrieb im Bezug auf die EMV eine passive Komponente darstellt, sind entsprechende Entstörmaßnahmen im Umrichter zielführend.

description: Water is key in the evolution of protoplanetary disks and the formation of comets and icy/water planets. While high excitation water lines originating in the hot inner disk have been detected in several T Tauri stars (TTSs), water vapor from the outer disk, where most of water ice reservoir is stored, was only reported in the closeby TTS TW Hya. We present spectrally resolved Herschel/HIFI observations of the young TTS DG Tau in the ortho- and para- water ground-state transitions at 557, 1113 GHz. The lines show a narrow double-peaked profile, consistent with an origin in the outer disk, and are ~19-26 times brighter than in TW Hya. In contrast, CO and [C II] lines are dominated by emission from the envelope/outflow, which makes H2O lines a unique tracer of the disk of DG Tau. Disk modeling with the thermo-chemical code ProDiMo indicates that the strong UV field, due to the young age and strong accretion of DG Tau, irradiates a disk upper layer at 10-90 AU from the star, heating it up to temperatures of 600 K and producing the observed bright water lines. The models suggest a disk mass of 0.015-0.1 Msun, consistent with the estimated minimum mass of the solar nebula before planet formation, and a water reservoir of ~1e2-1e3 Earth oceans in vapour, and ~100 times larger in the form of ice. Hence, this detection supports the scenario of ocean delivery on terrestrial planets by impact of icy bodies forming in the outer disk.

description: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has brought renewed attention to respiratory aerosol and droplet generation. While many studies have robustly quantified aerosol (<10 µm diameter) number and mass exhalation rates, fewer studies have explored larger droplet generation. This study quantifies respiratory droplets (>20 µm diameter) generated by a cohort of 76 adults and children using a water-sensitive paper droplet deposition approach. Unvoiced and voiced activities spanning different levels of loudness, different lengths of sustained phonation, and a specific manner of articulation in isolation were investigated. We find that oral articulation drives >20 µm droplet generation, with breathing generating virtually no droplets and speaking and singing generating on the order of 250 droplets min−1. Lip trilling, which requires extensive oral articulation, generated the most droplets, whereas shouting “Hey,” which requires minimal oral articulation, generated relatively few droplets. Droplet size distributions were all broadly consistent, and no significant differences between the children and adult cohorts were identified. By comparing the aerosol and droplet emissions for the same participants, the full size distribution of respiratory aerosol (0.5–1000 µm) is reported. Although <10 µm aerosol dominates the number concentration, >20 µm droplets dominate the mass concentration. Accurate quantification of aerosol concentrations in the 10–70 μm size range remains very challenging; more robust aerosol analysis approaches are needed to characterize this size range.
