The role of integrin-linked kinase in tumour angiogenesis and inflammation
Creators: name: Tan, Clara Chia-Hua
Publisher: name: University of British Columbia
Year: 2010

description: Integrins act as transducers of extracellular matrix-mediated cell signaling [i.e. cell signalling]. A critical signaling component downstream of integrin engagement is integrin-linked kinase (ILK), a serine/threonine protein kinase and adaptor protein, that interacts with the cytoplasmic domains of β1 and β3 integrins. ILK couples integrins and receptor tyrosine kinases to the cytoskeleton, thus mediating multiple downstream signaling events that regulate cell adhesion, survival, proliferation, migration and differentiation. Inappropriate ILK activity as a result of deregulated upstream mechanisms or altered transcription, results in epithelial cell transformation that recapitulates malignant cancer cell behaviour. I provide novel data demonstrating that ILK plays an indispensable role in regulating downstream targets that induce nitric oxide synthase (iNOS) expression and nitric oxide (NO) production in murine macrophages, and cyclooxygenase-2 (COX-2), a pro-inflammatory macromolecule, expression in both murine and human macrophages. Cells treated with a highly specific small molecule ILK inhibitor or transfected with a dominant-negative mutant of ILK showed decreased ILK activity resulting in inhibition of lipopolysaccacharide (LPS) stimulated iNOS and NO production and reduction in COX-2 expression in a protein kinase B (Akt/PKB)-dependent manner. I also propose a novel model for induction of NF-κB transcription, where phosphorylation of IκB at the serine 32 position directly or indirectly by ILK or Akt/PKB targets IκB for degradation; consequently NF-κB translocates to the nucleus to initiate transcription of pro-inflammatory molecules. In addition, ILK and Akt/PKB are stimulated in a PI3-kinase dependent manner. I provide evidence for a new paradigm involving ILK in the improper production of vascular endothelial growth factor (VEGF) in normoxic conditions, shedding light on the role of ILK in tumor angiogenesis [i.e. tumour angiogenesis]. Mechanistically, I show that activated ILK stimulates the expression of hypoxia-inducible factor-1α (HIF-1α) transcription factor, the major inducer of VEGF expression, through the phosphorylation of mammalian target of rapamycin in an Akt/PKB dependent manner in prostate cancer cells. In a positive feedback process, exposure of endothelial cells to VEGF stimulates a transient increase in ILK kinase activity in a PI-3 kinase-dependent manner. Inhibition of ILK activity using small interfering RNA or exposure to the ILK inhibitor uncouples endothelial cell migration and proliferation in response to VEGF.

description: We show that dilute magnetic impurities in a conventional superconductor give origin to an odd-frequency component of superconductivity, manifesting itself in Yu-Shiba-Rusinov bands forming within the bulk superconducting gap. Our results are obtained in a general model solved within the dynamical mean field theory. By exploiting a disorder analysis and the limit to a single impurity, we are able to provide general expressions that can be used to extract explicitly the odd-frequency superconducting function from scanning tunneling measurements.

Charge- and pair-density-wave orders in the one-band Hubbard model with dynamical mean field theory
Creators: name: Dash, Sidhartha Shankar

Publisher: name: arXiv
Year: 2020
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We study the charge-density-wave order and its competition with superconductivity in the one-band Hubbard model for high-$T_c$ superconducting cuprates. We use cluster dynamical mean field theory (CDMFT) at $T=0$. The one-band Hubbard model only contains copper atoms, and a physical charge-density-wave with charge excesses located on the oxygen atoms manifests itself as a bond-density-wave (BDW) within this context. It arises purely out of local correlation effects and also leads to a $s'$-wave pair-density-wave in the presence of $d$-wave superconductivity. The $d$-wave BDW is suppressed on increasing $U$ and is favored on increasing the magnitude of the second-neighbor hopping $t'$. Further, the $d$-wave BDW order is weakened when in competition with superconductivity, as seen in experiments. Additionally it behaves quite differently on varying $U$ in the superconducting state compared to the normal state.

The Nature of the Molecular Environment within 5 pc of the Galactic Center

description: We present a detailed study of molecular gas in the central 10pc of the Galaxy through spectral line observations of four rotation inversion transitions of NH3 made with the VLA. Updated line widths and NH3(1,1) opacities are presented, and temperatures, column densities, and masses are derived. We examine the impact of Sgr A East on molecular material at the Galactic center and find that there is no evidence that the expansion of this shell has moved a significant amount of the 50 km/s GMC. The western streamer, however, shows strong indications that it is composed of material swept-up by the expansion of Sgr A East. Using the mass and kinematics of the western streamer, we calculate an energy of E=(2-9)x10^{51} ergs for the progenitor explosion and conclude that Sgr A East was most likely produced by a single supernova. The temperature structure of molecular gas in the central ~20pc is also analyzed in detail. We find that molecular gas has a ``two-temperature'' structure similar to that measured by Huttemeister et al. (2003a) on larger scales. The largest observed line ratios, however, cannot be understood in terms of a two-temperature model, and most likely result from absorption of NH3(3,3) emission by cool surface layers of clouds. By comparing the observed NH3 (6,6)-to-(3,3) line ratios, we disentangle three distinct molecular features within a projected distance of 2pc from Sgr A*. Gas associated with the highest line ratios shows kinematic signatures of both rotation and expansion. The southern streamer shows no significant velocity gradients and does not appear to be directly associated with either the circumnuclear disk or the nucleus. The paper concludes with a discussion of the line-of-sight arrangement of the main features in the central 10pc.

We solve the generalized Klein-Gordon oscillator in the cosmic string space-time with a linear scalar potential and obtain the energy eigenvalue and corresponding eigenfunction. We show that the energy spectrum depends on the global parameters characterizing the space-time and the confining potential parameter. We also solve the generalized Klein-Gordon oscillator in a magnetic cosmic string background in the Kaluza-Klein theory with a linear scalar potential and analyze the analogue effect to the Aharonov-Bohm effect for bound states.

description: In der Öffentlichkeit werden die Provisionen, die Immobilienmakler in Österreich für ihre Tätigkeiten verlangen dürfen, immer wieder als zu hoch kritisiert. Bei genauerer Betrachtung der Rahmenbedingungen der einzelnen europäischen Länder zeigt sich jedoch, dass die Entlohnung der Dienstleistung von Immobilienmaklern nur sehr bedingt vergleichbar ist, da Ausbildung, gesetzliche Rahmenbedingungen, Zugang zum Beruf sowie die Aufteilung der Provision zwischen Abgeber und Abnehmer höchst unterschiedlich geregelt sind. Der Immobilienmakler ist umso bedeutender, je intransparenter der Markt ist, da er zur Steigerung der Markttransparenz beiträgt. Neben der Objektivierung des Marktes sorgt er für eine optimale Preisgestaltung des Objektes, bereitet dieses fachmännisch auf und sorgt für einen geordneten Ablauf der Transaktion. Die Kunden eines Immobilienmaklers haben divergierende Ansprüche, wobei der Verkäufer bzw. Vermieter einer Immobilie einen möglichst hohen Preis erzielen will, jedoch der Käufer bzw. Mieter einen möglichst geringen Preis zu zahlen bereit ist. Beide erwarten sich von einem Makler Seriosität und marktgerechte Preise. Ziel dieser Arbeit ist es, die Leistungen des Immobilienmaklers dem zu erwartenden Provisionsanspruch gegenüberzustellen. Man wird möglicherweise überrascht sein über die analysierten Leistungen und individuellen Tätigkeiten, die ein gewissenhafter Immobilienmakler für die Vermarktung einer Immobilie zu erfüllen hat. Es soll hierbei möglichst klar zum Ausdruck kommen, welchen Mehrwert jemand mit der Beiziehung eines Immobilienmaklers erzielt. Anhand von Fragebögen wurde auch die Auswirkung der gesetzlichen Änderungen auf den Immobilienmarkt erforscht. Besonders hervorzuheben ist dabei, dass es insbesondere im Bereich Gemeinschaftsgeschäft zu einem Umdenken kommt. Immer mehr Immobilienmakler sind nun bereit ihre Objekte mit anderen Maklerkollegen zu teilen, wobei in der Arbeit detailliert auf die Vorteile einer solchen Zusammenarbeit eingegangen wird.

Habitat selection and reproductive success of Lewis’s Woodpecker in the South Okanagan Valley
Creators: name: Zhu, Xiang
Publisher: name: University of British Columbia
Year: 2010

description: Lewis’s Woodpecker (Melanerpes lewis) has been listed as a species of special concern due to its range-wide decline in population numbers, possibly as a result of habitat loss and degradation. Management plans for this species need information on habitat requirements. However, little is understood about how habitat features affect nest site selection and reproductive success. I conducted the first study of the species in Canada, in the South Okanagan Valley, British Columbia, during 2004-2005 in an effort to fill this gap. I examined the habitat features influencing nest site selection using multiple logistic regression models. I also evaluated effects of habitat features and clutch initiation date on nest success using multiple Weibull regression models. Nest tree decay class and total basal area of large trees (DBH[greater than or equal to]50cm)/ha were the most important factors for nest site selection. Of the 57 nests monitored, 34 were located in snags, 22 in dead-top trees, and only one in a live tree. Despite the importance of large, decayed trees and newly-burned forest for nest site selection, these factors were unrelated to the subsequent nest success. The Mayfield estimate of overall nest success was 0.52 ± 0.08 (mean±S.E. n=57 nests). Early and late clutch initiations had higher nest success than intermediate clutch initiations, possibly due to seasonal variation in nest predation and cavity competition. But early clutch initiations were more likely to produce large clutches and fledged broods than late clutch initiations. Deep cavities with small entrances were able to effectively lower predation risk especially during the peak of nest predation. Overall, my results suggest that: (1) the habitat features related to nest site selection were not correlated with nest success; (2) early clutch initiations allowed the bird to gain the highest annual production rate; and (3) nest predation and cavity competition appeared to be important limiting factors to the species in the South Okanagan Valley. Key words: Lewis’s Woodpecker, cavity nesting bird, habitat attribute, nest site selection, reproductive ecology.

description: Financial services are a volatile industry. Since the financial crisis, the industry has been dominated by historically low interest rates - the main source of income for retail banks and ever increasing regulations. Mergers & Acquisitions are an important strategic tool in order to gain competitive advantage inorganically - economies of scale, market share or access to new technology. Yet a major challenge in the acquisition of a company is the determination of a fair value. There is no objective price for a company but based on the expectation of synergies and future income as well as an assessment of the seller's current situation, each buyer is ready to pay a different price. This Master's Thesis compares established valuation methodologies and their applicability on financial institutes. A case study evaluates strategic considerations and their outcomes for a banking merger.
BTZ gems inside regular Born-Infeld black holes

description: The regular black hole solution arising as a spherically symmetric vacuum solution of Born-Infeld gravity possesses an asymptotic interior structure which is very well described by a four dimensional generalization of the non-rotating BTZ metric. According to this picture no singularity exists, and instead, infalling observers experience a constant curvature manifold as they travel towards future null infinity. This is characterized by the BTZ event horizon. The exterior structure of the black hole is also studied, and it is shown that it corresponds to the Schwarzschild solution provided the black hole mass is not too small. In this way, the regular black hole state can be seen as a spacetime which connects two constant curvature asymptotic spaces, namely, the flat Minkowski spacetime in the outside region, and the locally AdS constant negative curvature one characterizing the BTZ-like asymptotic interior.

A functional quantum programming language

description: We introduce the language QML, a functional language for quantum computations on finite types. Its design is guided by its categorical semantics: QML programs are interpreted by morphisms in the category FQC of finite quantum computations, which provides a constructive semantics of irreversible quantum computations realisable as quantum gates. QML integrates reversible and irreversible quantum computations in one language, using first order strict linear logic to make weakenings explicit. Strict programs are free from decoherence and hence preserve superpositions and entanglement - which is essential for quantum parallelism.

Towards Heim and Neuhauser's Unimodality Conjecture on the Nekrasov-Okounkov polynomials

Through a new recursive formula, we show that if $A_{n,k}$ is the coefficient of $z^k$ in $Q_n(z)$, then $A_{n,k}$ is log-concave in $k$ for $k \ll n^{1/6}/\log n$ and monotonically decreasing for $k \gg \sqrt{n}\log n$. We also propose a conjecture that can potentially close the gap.

description: Does gravity influence local measurements? We use a dual-species atom interferometer with $2\,\text{s}$ of free-fall time to measure the relative acceleration between $^{85}$Rb and $^{87}$Rb wave packets in the Earth's gravitational field. Systematic errors arising from kinematic differences between the isotopes are suppressed by calibrating the angles and frequencies of the interferometry beams. We find an Eötvös parameter of $η= [1.6\; \pm\; 1.8\; \text{(stat)}\; \pm \; 3.4 \; \text{(sys)}] \times 10^{-12}$, consistent with zero violation of the equivalence principle. With a resolution of up to $1.4 \times 10^{-11} \, g$ per shot, we demonstrate a sensitivity to $η$ of $5.4 \times 10^{-11}\,/\sqrt{\text{Hz}}$.

description: The density-matrix renormalization group (DMRG) is a numerical algorithm for the efficient truncation of the Hilbert space of low-dimensional strongly correlated quantum systems based on a rather general decimation prescription. This algorithm has achieved unprecedented precision in the description of one-dimensional quantum systems. It has therefore quickly acquired the status of method of choice for numerical studies of one-dimensional quantum systems. Its applications to the calculation of static, dynamic and thermodynamic quantities in such systems are reviewed. The potential of DMRG applications in the fields of two-dimensional quantum systems, quantum chemistry, three-dimensional small grains, nuclear physics, equilibrium and non-equilibrium statistical physics, and time-dependent phenomena is discussed. This review also considers the theoretical foundations of the method, examining its relationship to matrix-product states and the quantum information content of the density matrices generated by DMRG.

A Software Search Interface for Heliophysics & Space Physics
Creators: name: Barnum, Julie
Publisher: name: Zenodo
Year: 2024

description: Currently, there exists no adequate interface to search on Heliophysics software like exists for publications. Thus, the newly awarded Heliophysics Software Search Interface (HSSI) from the NASA ROSES 2023 call seeks to improve upon Heliophysics software findability, discoverability, accessibility, citability, and searchability. In doing so, we will further the transparency and inclusiveness of Heliophysics software. The HSSI will allow users to come to one landing page to search for software related to their scientific tasks, starting with software packages contained within the Python in Heliophysics community (PyHC)[1], and eventually expanding out to Heliophysics code in other programming languages and software areas not covered yet in PyHC. Along with the easy search interface, we will also design and implement a software metadata structure for Heliophysics software registration and add a RestAPI to each. To encourage adoption from the community, information for the search interface and software metadata structure will be sourced from community discussions and usability testing. Lastly, in the spirit of reducing duplication of effort and collaboration with other science disciplines, the HSSI will build off NASA Goddard’s Exoplanet Modeling and Analysis Center (EMAC)[2], as well as the Heliophysics System Observatory Connect (HSOConnect)[3], and the current PyHC website search interface and supporting metadata. Additionally, open repositories such as Zenodo[4] and existing resource search capabilities such as the ADS[5] will be used for inspiration.

This talk will present an introduction to the HSSI and plans moving forward now that funding has been received to begin work in October 2024.

The Discovery of Extended Thermal X-ray Emission from PKS 2152-699: Evidence for a `Jet-cloud' Interaction

description: A Chandra ACIS-S observation of PKS 2152-699 reveals thermal emission from a diffuse region around the core and a hotspot located 10" northeast from the core. This is the first detection of thermal X-ray radiation on kiloparsec scales from an extragalactic radio source. Two other hotspots located 47" north-northeast and 26" southwest from the core were also detected. Using a Raymond-Smith model, the first hotspot can be characterized with a thermal plasma temperature of 2.6$\times10^6$ K and an electron number density of 0.17 cm$^{-3}$. These values correspond to a cooling time of about 1.6$\times10^7$ yr. In addition, an emission line from the hotspot, possibly Fe xxv, was detected at rest wavelength 10.04Å. The thermal X-ray emission from the first hotspot is offset from the radio emission but is coincident with optical filaments detected with broadband filters of HST/WFPC2. The best explanation for the X-ray, radio, and optical emission is that of a `jet-cloud' interaction. The diffuse emission around the nucleus of PKS 2152-699 can be modeled as a thermal plasma with a temperature of 1.2$\times10^7$ K and a luminosity of 1.8$\times10^{41}$ erg s$^{-1}$. This emission appears to be asymmetric with a small extension toward Hotspot A, similar to a jet. An optical hotspot (EELR) is seen less than an arcsecond away from this extension in the direction of the core. This indicates that the extension may be caused by the jet interacting with an inner ISM cloud, but entrainment of hot gas is unavoidable. Future observations are discussed.

description: We construct explicit mode expansions of various tree-level propagators in the Rindler -- de Sitter universe, also known as the static (or compact) patch of the de Sitter spacetime. We construct in particular the Wightman functions for thermal states having a generic temperature $T$. We give a fresh simple proof that the only thermal Wightman propagator that respects the de Sitter isometry is the restriction to the Rindler -- de Sitter wedge of the propagator for the Bunch--Davies state. It is the thermal state with $T = (2 π)^{-1}$ in the units of de Sitter curvature. We show that propagators with $T\ne(2π)^{-1}$ are only time translation invariant and have extra singularities on the boundary of the static patch. We also construct the expansions for the so-called alpha-vacua in the static patch and discuss the flat limit.

He joined the Worcestershires in June 1916, died November 1916. He served in the UK only. It's not known that he had any pre-war military service. Family have never seen a silver war badge, so died before discharge. Alfred's family was awarded a Dead Man's Penny. This is still in the family. Sandy's son chrome-plated it as part of a metalworking course.Alfred worked for his father in Worcester, a butcher, but left after a falling out with his father. He used to deliver on a horse. When he delivered to Perdiswell House, Worcester he rode his horse on the grass beside the drive and was reported by the customer. Alfred's father told him "do it again and I'll horse whip you!" He did it again, and got horse whipped.

description: An EPR-Bell type experiment carried out on an entangled quantum system can produce correlations stronger than allowed by local realistic theories. However there are correlations that are no-signaling and are more non local than the quantum correlations. Here we show that any correlations more non local than those achievable in an EPR-Bell type experiment necessarily allow -in the context of the quantum formalism- both for signaling and for generation of entanglement. We use our approach to rederive Cirel'son bound for the CHSH expression, and we derive a new Cirel'son type bound for qutrits. We discuss in detail the interpretation of our approach.

description: The polarization of the chi_{c2} produced in psi(2S) decays into gamma chi_{c2} is measured using a sample of 14*10^6 psi(2S) events collected by BESII at the BEPC. A fit to the chi_{c2} production and decay angular distributions in psi(2S) to gamma chi_{c2}, chi_{c2} to pi pi and KK yields values x=A_1/A_0=2.08+/-0.44 and y=A_2/A_0=3.03 +/-0.66, with a correlation rho=0.92 between them, where A_{0,1,2} are the chi_{c2} helicity amplitudes. The measurement agrees with a pure E1 transition, and M2 and E3 contributions do not differ significantly from zero.

description: We continue to study doubled aspects of algebroid structures equipped with the C-bracket in double field theory (DFT). We find that a family of algebroids, the Vaisman (metric or pre-DFT), the pre- and the ante-Courant algebroids are constructed by the analogue of the Drinfel'd double of Lie algebroid pairs. We examine geometric implementations of these algebroids in the para-Hermitian manifold, which is a realization of the doubled space-time in DFT. We show that the strong constraint in DFT is necessary to realize the doubled and non-trivial Poisson structures but can be relaxed for some algebroids. The doubled structures of twisted brackets and those associated with group manifolds are briefly discussed.

YB-1 is a downstream component of the PI3K/Akt signaling pathway and regulates EGFR in breast carcinoma : a mechanism for breast cancer growth
Creators: name: Wu, Chia-Cheng Joyce
Publisher: name: University of British Columbia

description: High level of activated or phosphorylated serine/threonine kinase Akt is commonly observed in aggressive breast cancer. Hence, the Akt signaling pathway has become a popular target for therapeutic interventions. Previously our lab discovered that phosphorylated Akt is co-expressed with a transcription/translation factor called the Y-box Binding Protein-1 (YB-1) and that Akt phosphorylates YB-1 at Ser102 in vitro. It was also found that YB-1, but not the YB-1 mutant in which Ser102 is mutated to alanine (YB-1A102), enhanced breast cancer cell growth. Since YB-1 was originally isolated as a DNA binding protein that interacts with the regulatory elements of the epidermal growth factor receptor (EGFR), we addressed the possibility that phosphorylated YB-1 stimulates breast cancer cell growth by up-regulating EGFR expression. First, we demonstrated that YB-1 was phosphorylated through the PI3K/Akt pathway ex vivo by immunoprecipitation and western blotting. We then illustrated that loss of Ser102 affects the nuclear translocation of YB-1, implying that Akt may also regulate YB-1 nuclear trafficking. By exogenously expressing YB-1 or YB-1A102 in breast cancer cell lines we showed that YB-1 but not YB-1A102 induced the levels of EGFR mRNA and protein. It was revealed that YB-1 bound to the -2kb of the EGFR promoter by chromatin immunoprecipitation. Interestingly, disruption of Ser102 prevented YB-1 from interacting with the first 1 kb of the EGFR promoter, indicating that binding to this region by YB-1 is regulated by the PI3K/Akt signaling. We then demonstrated that mutation of Ser 102 perturbed YB-1 from activating the -1kb of the EGFR promoter by luciferase reporter assays. Finally, since activation of Akt depends on 3-phosphoinositide-dependent protein kinase-1 (PDK1), we examined the potential of a PDK1 inhibitor, OSU-03012, to inhibit the functions of YB-1. It was found that OSU-03012 blocked YB-1 nuclear translocation and binding to the -1 kb promoter of EGFR. Together these results suggested that activation of the PI3K/Akt pathway leads to phosphorylation of YB-1 at Ser102, resulting in up-regulation of EGFR gene expression. Here we propose that Akt, YB-1, and EGFR may all function in the same pathway to promote breast cancer cell growth.

Cumulant expansion for ferrimagnetic spin (S_1, s_2) systems

description: We have generalized the application of cumulant expansion to ferrimagnetic systems of large spins. We have derived the effective Hamiltonian in terms of classical variables for a quantum ferrimagnet of large spins. A noninteracting gas of ferrimagnetic molecules is studied systematically by cumulant expansion to second order of ($Js/T$) where $J$ is the exchange coupling in each molecule, $s$ is the smaller spin ($S_1, s_2$) and $T$ is temperature. We have observed fairly good results in the convergent regime of the expansion, i.e $T > Js$. We then extend our approach to a system of interacting ferrimagnetic molecules. For one dimensional nearest neighbor interaction we have observed that the correlation of more than two neighboring sites is negligible at moderate and high temperature behavior. Thus the results of a single molecule can be applied to the chain of interacting molecules for temperatures greater than classical energy scale, i.e $T>JS_1s_2$. Finally we will discuss the effect of spin inhomogeneity on the accuracy of this method.

description: We employ the jackknife algorithm to analyze the propagation of the statistical quantum Monte Carlo error through the Bethe--Salpeter equation. This allows us to estimate the error of dynamical mean-field theory calculations of the susceptibility and of dynamical vertex approximation calculations of the self-energy. We find that the different frequency components of the susceptibility are uncorrelated, whereas those of the self-energy are correlated. For improving the quality of the correlation matrix taking sufficiently many jackknife bins is key, while for reducing the standard error of the mean sufficiently many Monte Carlo measurements are necessary. We furthermore show that even in the case of the self-energy, the finite covariance does not have a sizable influence on the analytic continuation.

description: We have developed two radiation-hard ASICs for optical data transmission in the ATLAS pixel detector at the LHC at CERN: a driver chip for a Vertical Cavity Surface Emitting Laser (VCSEL) diode for 80 Mbit/s data transmission from the detector, and a Bi-Phase Mark decoder chip to recover the control data and 40 MHz clock received optically by a PIN diode. We have successfully implemented both ASICs in 0.25 mm CMOS technology using enclosed layout transistors and guard rings for increased radiation hardness. We present results from circuits of final design and from irradiation studies with 24 GeV protons up to 62 Mrad (2.3 x 10^15 p/cm^2).

description: We use the terahertz (THz) emission spectroscopy to study femtosecond photocurrent dynamics in the prototypical 2D semiconductor, transition metal dichalcogenide MoSe$_2$. We identify several distinct mechanisms producing THz radiation in response to an ultrashort ($30\,$fs) optical excitation in a bilayer (BL) and a multilayer (ML) sample. In the ML, the THz radiation is generated at a picosecond timescale by out-of-plane currents due to the drift of photoexcited charge carriers in the surface electric field. The BL emission is generated by an in-plane shift current. Finally, we observe oscillations at about $23\,$THz in the emission from the BL sample. We attribute the oscillations to quantum beats between two excitonic states with energetic separation of $\sim100\,$meV.
