description: The supply chain of cilantro was modeled for growth and die-off of Escherichia coli (E. coli) O157:H7 from infield and harvesting, transportation and storage and ultimately consumption at home. Using Visual Basic for Applications (VBA) macros and @RISK software, a simulation model was developed for exposure and estimation of illnesses. Test scenarios were modeled to determine the relative importance of different factors on the risk of illness. The developed model was simulated using Monte Carlo technique and Latin Hypercube sampling for 100,000 iterations. Results showed an increase in the mean E. coli O157:H7 concentration along the supply chain for cilantro grown in both winter and summer weather conditions. In the winter, the mean pathogen concentration increased from 5.6×10-5 CFU/g to 24.7 CFU/g from after harvest to after home storage, respectively. In summer conditions, the mean pathogen concentration increased from 3.2×10-4 CFU/g to 5.2×10-2 CFU/g. The inner quartile ranges (IQRs) for the same model conditions showed a decrease in E. coli O157:H7 concentration along the supply chain for cilantro grown in both winter and summer weather conditions. This indicates a majority of situations result in a decrease in E. coli O157:H7 concentration along the supply chain however rare situations can occur where the concentration will increase greatly. With a prevalence of 0.1% E. coli O157:H7 contamination for cilantro post-harvest used for illustration, the model predicted the mean number of illnesses per year due to the consumption of E. coli O157:H7 contaminated cilantro in the United States as 86 and 164 for cilantro grown during winter and summer conditions, respectively. Sensitivity analysis results indicated that transportation temperatures and quality of irrigation water had the largest impact on the number of illnesses per year. Scenario testing results for different risk factors demonstrated the importance of limiting and reducing cross contamination along the production chain, especially at higher initial prevalence levels and preventing temperature abuse during transportation from farm to retail, when reducing overall risk of illness. The developed risk model can be used to estimate the microbiological risks associated with E. coli O157:H7 in cilantro and determine areas along the supply chain with the most effect on the final concentration per serving for future mitigation strategies.

description: This afterword offers a deliberately external view on the contributions gathered in this volume. The author—an anthropologist and not a Hellenist—was sensitive to the diversity of interpretations of the famous fragment, and even more so to the diversity of meanings of the term aiôn. At the time of Heraclitus, this term seems to have been understood in the sense of a “vital force” deciding the life span of the individual. Would this meaning be a concrete anchor for an abstract notion destined to open up widely? This is suggested by the later uses of the term aiôn, which over the centuries came to designate time in terms of its duration, its cyclical or linear character, or the impact it has on human life when it becomes destiny. It will be personified following the example of other abstract notions of ancient Greece. As for the child who pushes pawns but does not play for lack of a partner, while being adorned with sovereignty, it could constitute an image of the advance of time, free of any constraint, of any bond of dependence. The history of the interpretations of the fragment of Heraclitus offers rich material for comparative
 anthropology.

Synthesis and medium-dependent photochemistry of tetrahydro-1,4- Anthraquinones and Anthraquinols : structure-reactivity relationships from X-ray crystallography
Creators: name: Askari, Syed Hasan
Publisher: name: University of British Columbia
Year: 2010

description: Previous work from our laboratory has been concerned with investigating the photochemical reactivity of tetrahydro-1,4-naphthalenedione and tetrahydronaphthoquinol systems, both in the solid state and in solution. The fascinating results obtained prompted us to extend the studies to the analogous tetrahydro-1,4-anthracenediones, tetrahydro-5,12-naphthacenediones and tetrahydroanthraquinol systems. Tetrahydro-1,4-anthracenedione is expected to undergo bis-enolization with extreme ease, and therefore its preparation requires mild and neutral conditions. These compounds were prepared by Diels-Alder reaction between o-quinodimethane and p-benzoquinone and other p-substituted quinones o-Quinodimethane was generated in situ by sulphur dioxide extrusion from 3,6-dihydrobenzo[b]oxathiin-2-oxide. The photochemistry of the tetrahydro-1,4-anthracenediones, tetra-hydro-5,12-naphthalenedione and tetrahydroanthraquinols has been investigated both in the solid state and solution. The effect of the solid state medium on the photoreactivity, compared to the solution, is significant; the nature and/or the number of the photoproducts formed in the solid state is generally different from the results obtained in solution. These differences have been explained on the basis of the crystal and molecular structures of the reactants. Special steric effects, which may impede the photochemical reactions in the solid state have been identified. The values of the geometric parameters (d, r and A) for hydrogen atom abstraction are found to be similar to those observed in earlier studies by Scheffer et al. It has been found that the o-quinodimethane/2,3-dimethyl-l,4-naphthoquinone adduct affords, via β-hydrogen atom abstraction and closure of the resulting 1,3-biradical, a cyclopropanol. The cyclopro-panol itself undergoes photolysis initiated by a novel ring opening process. Irradiation of crystals of the adduct does not result in any cyclopropanol. The reasons for the non-reactivity of the Diels-Alder adduct in the solid state have been suggested to be due to the non-bonded steric interactions between the lattice neighbors as shown by the X-ray crystal structure. The photorearrangement of one substrate, namely 2,3,4a,9a-tetra-methyl-4a,9a,9,10-tetrahydro-1,4-anthracenedione is found to be controlled by the temperature, multiplicity, and phase of the reaction. By carrying out the reaction at or above room temperature or in the presence of a sensitizer or in the crystalline state, the reaction can be forced in one direction. Lowering the photolysis temperature causes the formation of another product. The nature of the photoproduct is independent of the temperature in the crystalline state. The results have been interpreted in terms of a required ring inversion which is needed for the formation of the low temperature photoproduct (see Scheme 44). The ring inversion is not allowed in the solid state.

Astrometric reduction methods are also presented. The OGLE-III data constitute a unique data set covering the Magellanic Clouds, Galactic bulge and Galactic disk fields monitored regularly every clear night since 2001 and being significant extension and continuation of the earlier OGLE observations. With the earlier OGLE-II and OGLE-I photometry some of the observed fields have now 16-year long photometric coverage.

Non-Markovian Stochastic Liouville equation and its Markovian representation. Extensions of the continuous time random walk approach

description: Some specific features and extensions of the continuous time random walk (CTRW) approach are analyzed in detail within the Markovian representation (MR) and CTRW-based non-Markovian stochastic Liouville equation (SLE). In the MR CTRW processes are represented by multidimensional Markovian ones. In this representation the probability distribution function (PDF) W(t) of fluctuation renewals is associated with that of reoccurrences in a certain jump state of some Markovian controlling process. Within the MR the non-Markovian SLE, which describes the effect of CTRW-like noise on relaxation of dynamic and stochastic systems, is generalized to take into account the influence of relaxing systems on statistical properties of noise. The generalized non-Markovian SLE is applied to study two modifications of the CTRW approach. One of them considers the cascaded CTRWs in which the controlling process is actually CTRW-like one controlled by another CTRW process, controlled in turn by the third one, etc. Within the MR simple expression for the PDF W(t) of total controlling process is obtained in terms of Markovian variants of controlling PDFs in the cascade. The expression is shown to be especially simple and instructive in the case of anomalous processes determined by long time tailed W(t). The cascaded CTRWs can model the effect of complexity of a system on relaxation kinetics (in glasses, fractals, branching media, ultrametric structures, etc.). Another CTRW-modification describes the kinetics of processes governed by fluctuating W(t). Within the MR the problem is analyzed in a general form without restrictive assumptions on correlations of PDFs of consecutive renewals. The analysis shows that W(t) can strongly affect the kinetics of the process. Possible manifestations of this effect are discussed.

Tunable bandgaps and symmetry breaking in magneto-mechanical metastructures inspired by multi-layer 2D materials

description: In this Letter, we introduce a paradigm to realize magneto-mechanical metastructures inspired by multi-layer 2D materials, such as graphene bilayers. The metastructures are intended to capture two aspects of their nanoscale counterparts. One is the multi-layer geometry, which is implemented by stacking hexagonal lattice sheets. The other is the landscape of weak inter-layer forces, which is mimicked by the interactions between pairs of magnets located at corresponding lattice sites on adjacent layers. We illustrate the potential of this paradigm through a three-layer prototype. The two rigid outer lattices serve as control layers, while the thin inner layer is free to experience flexural motion under the confining action of the magnetic forces exchanged with the outer ones, thus behaving as a lattice on elastic foundation. The inner layer is free to rotate relatively to the others, giving rise to a rich spectrum of inter-layer interaction patterns. Our objective is to determine how the dynamical response can be tuned by changing the twist angle between the layers. Specifically, we demonstrate experimentally that switching between different stacking patterns has profound consequences on the phonon landscape, opening and closing bandgaps in different frequency regimes.
Fluctuation Effect in the π-flux State for Undoped High-Temperature Superconductors

Publisher: name: arXiv
Year: 2008
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: The effect of fluctuations about the pi-flux mean field state for the undoped high-temperature superconductors is investigated. It is shown that fluctuations of the mean fields lead to a self-energy correction that doubles the band width of the fermion dispersion in the lowest order. The dynamical mass generation is associated with the self-energy effect due to the interaction mediated by the Lagrange multiplier field, which is introduced to impose the constraint on the fermions. A self-consistent picture about the mass generation and the prop- agation of the Lagrange multiplier field without damping is proposed. The antiferromagnetic long-range ordering is described without introducing an additional repulsive interaction. The theory suggests a natural framework to study spin disordered systems in which fermionic excitations are low-lying excitations.

description: In der Forschungsarbeit wird die Zeitungskommunikation des 18. Jahrhunderts aus sprachwissenschaftlicher Perspektive untersucht. Es wird gezeigt, wie sich das Textsortenrepertoire der Zeitung weiterentwickelte, welche sprachlichen Wandelprozesse stattfanden und wie die Zeitung übergreifend allmählich zu einem Massenmedium avancierte. Der textlinguistische Zugang auf die Zeitungssprache wird an den relevanten Stellen ergänzt durch einschlägige Erkenntnisse aus der historischen Presseforschung und der linguistischen Kulturanalyse. So wird etwa nachgezeichnet, wie sich die Zeitungsschreiber im Laufe des Jahrhunderts immer stärker von den Einflüssen der Kanzleisprachen lösten und Formulierungsstrategien etablierten, die auf die Anforderungen des journalistischen Berichtens abgestimmt waren. Mit diesen und weiteren Ergebnissen wird der Versuch angestellt, eine Forschungslücke der Sprachgeschichtsforschung zu schließen, in der die Zeitungen des 18. Jahrhunderts bisher lediglich randständig untersucht wurden.
description: This study focusses on daily newspapers from the 18th century from a linguistic perspective. It shows the repertoire of different journalistic text types and their historical development and demonstrates the newspaper's progress to becoming the biggest and most influental form of mass media. The textlinguistic approach is combined with research from the fields of historical publicity and cultural linguistics. The analysis thus shows, for example, that journalists start to distance themselves from influences of the so-called "Kanzleisprachen" (i.e. the administrative language) in order to develop a form of new journalistic writing. These and further results are part of the attempt to gain empirical knowledge about 18th century German newspapers that have barely been examined in historical linguistics.
Critical Ignition Conditions of Structural Materials by Cylindrical Firebrands

description: Smoldering firebrands (embers) are a major cause of ignition and eventual structural damage during wildfires at the wildland-urban interface (WUI). These small pieces of wood can loft several kilometers ahead of the main flame front and ignitespot fires directly on structural elements such as decks. In this research, dense structural materials such as wood and engineered wood will be studied with a focus on capturing the critical thermal conditions necessary for ignition. Unique to this study will be a configuration where whole piles of firebrands are placed on the recipient material, emulating observations from WUI fires. In order to design appropriate fire safety standards at the WUI and, someday, to model the propagation of these fires, the conditions leading to ignition of common WUI materials by piles of lofted firebrands must be quantified. Firebrands were modeled using small cylindrical wooden dowels which were ignited and placed in a small-scale wind tunnel. Two tests were performed for each loading condition of firebrands, one studying ignition of wooden structural elements such as decking and marine-grade plywood and another measuring temperatures and heat fluxes over an inert piece of ceramic insulation. A single-point water-cooled heat flux gauge was used for time-resolved measurements of heat flux at the center of the inert setup surrounded by thin-skin calorimeters and K-type thermocouples which allowed for a spatial characterization of heating. The wind speed was the main quantity of interest changed during the test to determine the effects of wind speed on the heat flux released from the glowing dowels to recipient fuels. The results showed a drastic increase in heating from piles of firebrands vs. individual brands. The piles also produced higher heat fluxes under increasing winds. This is due, for the most part, to higher surface temperatures resulting from increased surface oxidation under higher wind speeds. Both smoldering and flaming ignition of wood was found to be similarly dependent on wind speed. Larger piles also produced higher peak heat fluxes at the center of the pile, highlighting the role of re-radiation within the pile influencing heat fluxes to recipient fuels. Critical heat flux and firebrand loading conditions required to achieve smoldering and flaming ignition of structural materialsused in the WUI are determined by comparing tests with inert and flammable fuels. These critical conditions can be used to model the propagation of WUI fires over structural elements to design appropriate fire safety standards at the WUI. A non-dimensional relationship incorporating fuel type, geometry, and ambient conditions is also proposed to describe the results.

description: Dark matter particles with Planck-scale mass ($\simeq10^{19}\text{GeV}/c^2$) arise in well-motivated theories and could be produced by several cosmological mechanisms. Using a blind analysis of data collected over a 813 d live time with DEAP-3600, a 3.3 t single-phase liquid argon-based dark matter experiment at SNOLAB, a search for supermassive dark matter was performed, looking for multiple-scatter signals. No candidate signal events were observed, leading to the first direct detection constraints on Planck-scale mass dark matter. Leading limits constrain dark matter masses between $8.3\times10^{6}$ and $1.2\times10^{19} \text{GeV}/c^2$, and cross sections for scattering on $^{40}$Ar between $1.0\times10^{-23}$ and $2.4\times10^{-18} \text{cm}^2$. These are used to constrain two composite dark matter models.

description: We present an interferometric and single dish study of small organic species toward Comets C/1995 O1 (Hale-Bopp) and C/2002 T7 (LINEAR) using the BIMA interferometer at 3 mm and the ARO 12m telescope at 2 mm. For Comet Hale-Bopp, both the single-dish and interferometer observations of CH3OH indicate an excitation temperature of 105+/-5 K and an average production rate ratio Q(CH3OH)/Q(H2O)~1.3% at ~1 AU. Additionally, the aperture synthesis observations of CH3OH suggest a distribution well described by a spherical outflow and no evidence of significant extended emission. Single-dish observations of CH3CN in Comet Hale-Bopp indicate an excitation temperature of 200+/-10 K and a production rate ratio of Q(CH3CN)/Q(H2O)~0.017% at ~1 AU. The non-detection of a previously claimed transition of cometary (CH2OH)2 toward Comet Hale-Bopp with the 12m telescope indicates a compact distribution of emission, D<9'' (<8500 km). For the single-dish observations of Comet T7 LINEAR, we find an excitation temperature of CH3OH of 35+/-5 K and a CH3OH production rate ratio of Q(CH3OH)/Q(H2O)~1.5% at ~0.3 AU. Our data support current chemical models that CH3OH, CH3CN and (CH2OH)2 are parent nuclear species distributed into the coma via direct sublimation off cometary ices from the nucleus with no evidence of significant production in the outer coma.

description: Quiescent black hole X-ray binaries (X-ray luminosities <1e34 erg/s) are believed to be fed by hot accretion flows that launch compact, relativistic jets. However, due to their low luminosities, quiescent jets have been detected in the radio waveband from only five systems so far. Here, we present radio observations of two quiescent black hole X-ray binaries with the Australia Telescope Compact Array. One system, GS 1124-684, was not detected. The other system, BW Cir, was detected over two different epochs in 2018 and 2020, for which we also obtained quasi-simultaneous X-ray detections with Chandra and Swift. BW Cir is now the sixth quiescent X-ray binary with a confirmed radio jet. However, the distance to BW Cir is uncertain, and we find that BW Cir shows different behaviour in the radio/X-ray luminosity plane depending on the correct distance. Estimates based on its G-type subgiant donor star place BW Cir at >25 kpc, while initial optical astrometric measurements from Gaia Data Release 2 suggested likely distances of just a few kpc. Here, we use the most recent measurements from Gaia Early Data Release 3 and find a distance d=7.1(+4.8/-3.9) kpc and a potential kick velocity PKV=165(+81/-17) km/s, with distances up to ~20 kpc possible based on its parallax and proper motion. Even though there is now less tension between the parallax and donor-star based distance measurements, it remains an unresolved matter, and we conclude with suggestions on how to reconcile the two measurements.

Association of NMT2 expression with patient clinicopathological features in DBCL (analyzed from the GSE31312 cohort). Table S3. PCLX-001 and PCLX-002 sensitive cells have multiple origins. The treated cell lines were grouped according to their sensitivity to PCLX-001 and PCLX-002 (IC50). The cell lines were sorted into quartiles representing NMTI-sensitive (0–25%), less sensitive (25–50%), less resistant (50–75%), and resistant (75–100%) cells. The origin of the cells sensitive to PCLX-001 [22] and PCLX-002 [31] is not restricted to hematologic cancers, but could also be found in cells originating from solid tumors. Therefore, MISS-54 is not a signature of hematological cancers. Table S4. List of the 54 genes included in the Myristoylation Inhibition Sensitive Signature (MISS-54). Table S5.

description: In this work, a plasmonic right-angled waveguide bend and divider are proposed. Using the Transformation Optics (TO) approach the transformation media of a bend and a T-shaped divider are obtained. Such media with continuous refractive index are realized with the help of graphene in the terahertz frequency range, key to effectively guiding the surface plasmon polariton (SPP) propagation on the 90 degree curves. Components with such capability are promising for THz device applications.

description: We study the ferromagnetism in the compound (Zn,Mn)O within the Haldane-Anderson impurity model by using the quantum Monte Carlo technique and the tight-binding approximation for determining the host band-structure and the impurity-host hybridization. This computational approach allows us to determine how the host crystal structure influences the impurity bound state, which plays an important role in the development of the ferromagnetic (FM) correlations between the impurities. We find that the FM correlations are strongly influenced by the crystal structure. In particular, in p-type (Zn,Mn)O, we observe the development of FM correlations with an extended range at low temperatures for wurtzite and zincblende crystal structures. However, for the rocksalt structure no FM correlations are observed between the impurities. In addition, in n-type ZnO with magnetic impurities, the impurity bound state and FM correlations are not found.

description: We describe in detail the application of four qubit cluster states, built on the simultaneous entanglement of two photons in the degrees of freedom of polarization and linear momentum, for the realization of a complete set of basic one-way quantum computation operations. These consist of arbitrary single qubit rotations, either probabilistic or deterministic, and simple two qubit gates, such as a c-not gate for equatorial qubits and a universal c-phase (CZ) gate acting on arbitrary target qubits. Other basic computation operations, such as the Grover's search and the Deutsch's algorithms, have been realized by using these states. In all the cases we obtained a high value of the operation fidelities. These results demonstrate that cluster states of two photons entangled in many degrees of freedom are good candidates for the realization of more complex quantum computation operations based on a larger number of qubits.

description: The Wolf Creek Dam situated on the Cumberland River in the state of Kentucky, United States is a multipurpose dam generating hydroelectricity, providing flood risk reduction, supporting year-round navigation on the lower Cumberland River, and it creating Lake Cumberland for recreation and water supply. The latter is a popular tourist attraction. Because of piping and internal erosion problems in the dam's foundation, it is a USACE top-priority structure. This thesis experiments with and tests the applicability of a stochastic simulation of the dam using historical inflow data based on a model built on GoldSim™. The model uses standard operating rules of the Dam to spot possible failures to the turbines that could affect the performance of the dam. In addition, the model simulates the behavior of the dam 50 years in to the future during which time the components reach their close to their maximum life. Results of the study suggest that simulation models of this type may serve to provide information for reliability-based maintenance strategies, and to help identify adverse patterns of dam performance which may be addressed through asset management.

description: We derive on-shell recursion relations for nonrelativistic effective field theories (EFTs) with enhanced soft limits. The recursion relations are illustrated through analytic calculation of tree-level scattering amplitudes in theories with a complex Schrödinger-type field, real scalar with linear dispersion relation, and real scalar with Lifshitz-type dispersion relation. Our results show that the landscape of gapless nonrelativistic EFTs with local $S$-matrix can be constrained by soft theorems and the consistency of the low-energy $S$-matrix similarly to massless relativistic EFTs.

description: The purpose of this thesis is to study the modern international literature on the latest data on benzodiazepines (diazepam, lorazepam, midazolam, temazepam) and their therapeutic uses. Benzodiazepines are CNS depressants with hypnotic, anxiolytic and antiepileptic effects. An evaluation of the pharmacokinetic and pharmacodynamic characteristics of benzodiazepines and monitoring of their therapeutic concentrations is carried out. In addition, the paper deals with the toxicity of benzodiazepines in overdose situations and the development of tolerance and dependence on these drugs. Particular attention was given to the phenomenon of postmortem redistribution in fatal cases and the appropriate methods of analysis of benzodiazepines in biological materials were clarified. This dissertation is a comprehensive monograph on diazepam, lorazepam, midazolam and temazepam, from the point of view of clinical and forensic toxicology

description: We describe new solutions for open string moving in AdS_5 and ending in the boundary, namely dual to Wilson loops in N=4 SYM theory. First we introduce an ansatz for Euclidean curves whose shape contains an arbitrary function. They are BPS and the dual surfaces can be found exactly. After an inversion they become closed Wilson loops whose expectation value is $W=\exp(-\sqrtλ)$. After that we consider several Wilson loops for N=4 SYM in a pp-wave metric and find the dual surfaces in an AdS_5 pp-wave background. Using the fact that the pp-wave is conformally flat, we apply a conformal transformation to obtain novel surfaces describing strings moving in AdS space in Poincare coordinates and dual to Wilson loops for N=4 SYM in flat space.

The binding of an afimbrial bacterial surface adhesin to glycophorin using aqueous polymer two-phase partitioning
Creators: name: Jones, Andrew John Melvill
Publisher: name: University of British Columbia
Year: 2010

description: Colonisation by many bacteria and viruses is now thought to depend upon their ability to adhere to host cells via proteinacious surface appendages called adhesins. Information relevant to the prevention and cure of many diseases therefore is supplied by knowledge of this adhesive process, especially the chemistry of the binding and the structure of the binding molecules. At this time, the structure of very few adhesin receptors is known. Similarly, the quaternary and primary structure of only a small number of adhesins is currently available. Those associated with Escherichia coli are known in some cases to be arranged as helical coils with repeating proteinacious subunits with molecular weights of 10-30 kDa, however there is conflicting information on the distribution along these coils of the polypeptide involved in adhesion. Thermodynamic binding studies have not yet been used to clarify this problem because of the size of the receptors for the adhesins. This thesis presents a thermodynamic study of the binding between the adhesin from an F41+ E.coli and its receptor, glycophorin, from the human red blood cell membrane using an aqueous polymer two-phase system. The study shows that 2.4±0.8 glycophorin molecules bind to the predominant subunit of this adhesin, suggesting that this subunit has one binding site, since glycophorin dissolves as a dimer. It is proposed that the assay could be used, in addition, to obtain information on the chemical specificity and the thermodynamics of this particular reaction, in order to obtain a broader understanding of the colonisation and infection by this particular pathogen.

description: Biological connectivity is the connection of habitats through the movement of organisms that need to utilize said habitats to maintain their life history. Macroinvertebrate communities in freshwater can create biological connectivity by dispersing between temporary and permanent water sources. For this study, I collected and analyzed seasonal and temporal macroinvertebrate data to understand macroinvertebrate communities in six Delmarva Bays and four surrounding streams and identify potential overlapping genera between habitats. Environmental data was also collected to understand seasonal and temporal similarities and differences between Delmarva Bays and streams. For environmental data, Delmarva Bays and streams were most similar during the winter sampling period and become progressively dissimilar until summer sampling periods. For macroinvertebrate data, there were seventeen overlapping taxa that were found within predator and collector-gather feeding guilds. From this data, I can conclude that there is a potential for isolated wetlands and streams to have a biological connection.

description: This report discusses research at the University of Texas at Austin that is directed toward the production and study of thin films with noteworthy optical and electrical properties. The properties of transition metal dichalcogenide monolayers, such as MoS₂ and WSe₂, are discussed in the context of light-matter interactions to lead into an overview of exciton-polaritons and the efforts by researchers at the University to produce optical systems favorable to their creation and maintenance. This topic necessarily includes the work done to make highly engineered optical thin films known as distributed Bragg reflectors through an intensively controlled manufacturing process called atomic layer deposition. Attempts were made to produce a strong light-matter coupling in a system comprised of a MoS₂ monolayer sandwiched between two distributed Bragg reflectors made from alternating layers of Al₂O₃ and HfO₂. The results of those experiments are discussed, and so are those of an unsuccessful adaptation of a recipe for growing WSe₂ monolayers.
