description: We aim to understand how stellar parameters such as mass and rotation impact the distribution of starspots on the stellar surface. To this purpose, we have used Doppler imaging to reconstruct the surface brightness distributions of three fully convective M dwarfs with similar rotation rates. We secured high cadence spectral time series observations of the 5.5 AU separation binary GJ 65, comprising GJ 65A (M5.5V, Prot = 0.24 d) and GJ 65B (M6V, Prot = 0.23 d). We also present new observations of GJ 791.2A (M4.5V, Prot = 0.31 d). Observations of each star were made on two nights with UVES, covering a wavelength range from 0.64 - 1.03 microns. The time series spectra reveal multiple line distortions, which we interpret as cool starspots and which are persistent on both nights suggesting stability on the timescale of 3 days. Spots are recovered with resolutions down to 8.3 degs at the equator. The global spot distributions for GJ 791.2A are similar to observations made a year earlier. Similar high latitude and circumpolar spot structure is seen on GJ791.2A and GJ 65A. However, they are surprisingly absent on GJ 65B, which instead reveals more extensive, larger, spots concentrated at intermediate latitudes. All three stars show small amplitude latitude-dependent rotation that is consistent with solid body rotation. We compare our measurements of differential rotation with previous Doppler imaging studies and discuss the results in the wider context of other observational estimates and recent theoretical predictions.

description: The aim of this research is to explore the similarity and differences international students encounter while studying and living in a regional area as compared to their homeland. This study builds on both academic and lifestyle issues previous identified in research and explore the international students' experiences on their academic adjustments while living in a regional area. The findings of this investigation identified three themes: education, finance and culture. The analysis identified that students experience some level of difficulties at an initial stage but were positively accustomed to the local settings after a period of time. Finally, these and the findings in this paper are valuable to educational institutions especially those of regional areas seeking to understand what and how international students behave and act when studying and living in a regional area.

description: The current mobile applications have rapidly growing memory footprints, posing a great challenge for memory system design. Insufficient DRAM main memory will incur frequent data swaps between memory and storage, a process that hurts performance, consumes energy and deteriorates the write endurance of typical flash storage devices. Alternately, a larger DRAM has higher leakage power and drains the battery faster. Further, DRAM scaling trends make further growth of DRAMin the mobile space prohibitive due to cost. Emerging non-volatile memory (NVM) has the potential to alleviate these issues due to its higher capacity per cost than DRAM and mini-mal static power. Recently, a wide spectrum of NVM technologies, including phase-change memories (PCM), memristor, and 3D XPoint have emerged. Despite the mentioned advantages, NVM has longer access latency compared to DRAMand NVM writes can incur higher latencies and wear costs. Therefore integration of these new memory technologies in the memory hierarchy requires a fundamental rearchitect-ing of traditional system designs. In this work, we propose a hardware-accelerated memory manager (HMMU) that addresses both types of memory in a flat space address space. We design a set of data placement and data migration policies within this memory manager, such that we may exploit the advantages of each memory technology. By augmenting the system with this HMMU, we reduce the overall memory latency while also reducing writes to the NVM. Experimental results show that our design achieves a 39% reduction in energy consumption with only a 12% performance degradation versus an all-DRAM baseline that is likely untenable in the future.

description: [transcription] À Vézenobres, ce 6e décembre 1775.
Vous n’ignorez pas, Monsieur, qu’il faut être toujours un peu en garde contre les promesses de M. l’abbé Mauric et quelquefois même contre ses assertions. Il sait cependant qu’il m’aurait fait et me fera toujours plaisir de venir ici et je vous serai obligé de vouloir bien le lui répéter de ma part.
J’ai de nouveaux remerciements à vous faire des douze jolies plantes de Colutea maritime, que j’ai reçues en fort bon état et que j’ai commencé à faire planter dès hier. Les gens de mon âge ne doivent jamais rien différer à faire pour l’année qui vient, ni même pour le lendemain. Une demi-douzaine de plantes m’auraient suffi car je n’en ai que deux ou trois à planter, mais je ferai mettre le reste en un autre place en cas de besoin.
Ne vous en rapportez pas à l’abbé Mauric quand vos affaires vous permettront de me faire l’amitié de venir ici. Car ces affaires que je crains qui ne soient un peu délabrées ne lui laissent pas toujours la liberté de choisir son temps.
C’est quelque chose d’étonnant que la multitude de livres qui nous inonde depuis quelque temps. Il y en a quelques-uns d’assez curieux mais par malheur ce sont [ceux] là qui sont précisément les plus dangereux soit pour la religion soit pour les mœurs, deux choses qui marchent toujours de compagnie.
J’ai à me plaindre de ce que vous m’écrivez toujours avec trop de cérémonie. Regardez-moi s’il vous plait comme votre ami et comme un homme vrai, simple et qui sera toujours, mon cher Monsieur, votre très humble et très obéissant serviteur.

Calvière père.

description: The group of local unitary transformations acts on the space of n-qubit pure states, decomposing it into orbits. In a previous paper we proved that a product of singlet states (together with an unentangled qubit for a system with an odd number of qubits) achieves the smallest possible orbit dimension, equal to 3n/2 for n even and (3n + 1)/2 for n odd, where n is the number of qubits. In this paper we show that any state with minimum orbit dimension must be of this form, and furthermore, such states are classified up to local unitary equivalence by the sets of pairs of qubits entangled in singlets.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: A new method for non-perturbative calculation of Green functions in quantum mechanics and quantum field theory is proposed. The method is based on an approximation of Schwinger-Dyson equation for the generating functional by exactly soluble equation in functional derivatives. Equations of the leading approximation and the first step are solved for $ϕ^4_d$-model. At $d=1$ (anharmonic oscillator) the ground state energy is calculated. The renormalization program is performed for the field theory at $d=2,3$. At $d=4$ the renormalization of the coupling involves a trivialization of the theory.

On the consistency of ZF with an elementary embedding from $V_{λ+2}$ into $V_{λ+2}$

description: According to a theorem due to Kenneth Kunen, under ZFC, there is no ordinal $λ$ and non-trivial elementary embedding $j:V_{λ+2}\to V_{λ+2}$. His proof relied on the Axiom of Choice (AC), and no proof from ZF alone has been discovered.
 $I_{0,λ}$ is the assertion, introduced by W. Hugh Woodin, that $λ$ is an ordinal and there is an elementary embedding $j:L(V_{λ+1})\to L(V_{λ+1})$ with critical point ${<λ}$. And $I_0$ asserts that $I_{0,λ}$ holds for some $λ$. The axiom $I_0$ is one of the strongest large cardinals not known to be inconsistent with AC. It is usually studied assuming ZFC in the full universe $V$ (in which case $λ$ must be a limit ordinal), but we assume only ZF.
 We prove, assuming ZF + $I_{0,λ}$ + "$λ$ is an even ordinal", that there is a proper class transitive inner model $M$ containing $V_{λ+1}$ and satisfying ZF + $I_{0,λ}$ + "there is an elementary embedding $k:V_{λ+2}\to V_{λ+2}$"; in fact we will have $k\subseteq j$, where $j$ witnesses $I_{0,λ}$ in $M$. This result was first proved by the author under the added assumption that $V_{λ+1}^\#$ exists; Gabe Goldberg noticed that this extra assumption was unnecessary. If also $λ$ is a limit ordinal and $λ$-DC holds in $V$, then the model $M$ will also satisfy $λ$-DC.
 We show that ZFC + "$λ$ is even" + $I_{0,λ}$ implies $A^\#$ exists for every $A\in V_{λ+1}$, but if consistent, this theory does not imply $V_{λ+1}^\#$ exists.

First, white dwarfs are described by a Fermi gas model of degenerate electrons and neutrons and effects from general relativity are examined. For neutron star matter, the influence of a finite fraction of protons and electrons and of strong nucleon-nucleon interactions are studied. The nucleon--nucleon interactions are introduced within a Hartree-Fock scheme using a Skyrme-type interaction. Finally, masses and radii of neutron stars are computed for given central pressure.

Coordinated Assembly of the Mitochondrial Electron Transport Chain

description: Mitochondrial oxidative phosphorylation is an efficient source of cellular energy. This pathway couples the oxidation of NADH and FADH2 to the establishment of an electrochemical gradient across the inner mitochondrial membrane to facilitate ATP generation. The respiratory chain is comprised of five complexes; however, these are not simple enzymes. Rather, they are highly intricate membrane-bound complexes. As such, the biogenesis of these complexes presents the cell with numerous problems. Thus, the cell expresses dozens of assembly factors that are required to support the biogenesis of individual complexes. In the end, this promotes cellular energy production and protects the cell from potentially damaging insults. Succinate dehydrogenase (SDH) or complex II is a member of the electron transport chain (ETC) and TCA cycle. It plays a central role in cellular energy generation and mutations in the genes encoding SDH subunits and assembly factors are associated with human disease, including cancer and neurodegeneration. This highly conserved family supports the maturation of SDHA/Sdh1, the catalytic subunit of SDH. As such, Sdh8 functions as an Sdh1-specific chaperone and prevents the spurious generation of reactive oxygen species during the assembly process. In Drosophila, Sdhaf4 is required to prevent neurodegeneration and maintain normal motility. In the end, this work has expanded our understanding of the SDH assembly pathway and provided novel insights into the development of SDH-deficient pathologies. In addition to the canonical cytosolic pathway, eukaryotic cells have maintained a mitochondrial fatty acid synthesis pathway (FASII). This pathway is homologous to prokaryotic fatty acid synthesis and utilizes a number of enzymes that interact transiently with the acyl carrier protein (ACP) to support elongation of nascent acyl chains. Herein, we describe a novel and unexpected role for ACP and FASII in the assembly and activation of the ETC. As such, FASII-dependent synthesis of ACP-bound acyl chains activates a network of complex-specific assembly factors to support the assembly of the ETC complexes and synthesis of their essential cofactors. In the end, FASII and ACP couple mitochondrial acetyl-CoA to ETC biogenesis.

We measure the branching fractions Br(B^+-> \bar{K}^0 K^+ = (1.22^{+0.32+0.13}_{-0.28-0.16})x10^{-6} and Br(B^0-> \bar{K}^0 K^0) = (0.87^{+0.25}_{-0.20} +- 0.09)x10^{-6}, and partial-rate asymmetries A_{CP}(B^+-> \bar{K}^0 K^+) = 0.13^{+0.23}_{-0.24}+- 0.02 and A_{CP}(B^0-> \bar{K}^0 K^0) = -0.58^{+0.73}_{-0.66}+- 0.04. From a simultaneous fit we also obtain Br(B^+-> K^0π^+)= (22.8^{+0.8}_{-0.7} +- 1.3)x 10^{-6} and A_{CP}(B^+-> K^0 π^+) = 0.03 +- 0.03 +- 0.01. The first and second error in the branching fractions and the partial-rate asymmetries are statistical and systematic, respectively. No signal is observed for B^0-> K^+ K^- decays, and for this branching fraction we set an upper limit of 4.1x10^{-7} at the 90% confidence level.

description: The popularity of the Semantic Web (SW) encourages organizations to organize and publish semantic data using the RDF model. This growth poses new requirements to Business Intelligence (BI) technologies to enable On-Line Analytical Processing (OLAP)-like analysis over semantic data. The incorporation of semantic data into a Data Warehouse (DW) is not supported by the traditional Extract-Transform-Load (ETL) tools because they do not consider semantic issues in the integration process. In this paper, we propose a layer-based integration process and a set of high-level RDF-based ETL constructs required to define, map, extract, process, transform, integrate, update, and load (multidimensional) semantic data. Different to other ETL tools, we automate the ETL data flows by creating metadata at the schema level. Therefore, it relieves ETL developers from the burden of manual mapping at the ETL operation level. We create a prototype, named Semantic ETL Construct (SETLCONSTRUCT), based on the innovative ETL constructs proposed here. To evaluate SETLCONSTRUCT, we create a multidimensional semantic DW by integrating a Danish Business dataset and an EU Subsidy dataset using it and compare it with the previous programmable framework SETLPROG in terms of productivity, development time and performance. The evaluation shows that 1) SETLCONSTRUCT uses 92% fewer Number of Typed Characters (NOTC) than SETLPROG, and SETLAUTO (the extension of SETLCONSTRUCT for generating ETL execution flow automatically) further reduces the Number of Used Concepts (NOUC) by another 25%; 2) using SETLCONSTRUCT, the development time is almost cut in half compared to SETLPROG, and is cut by another 27% using SETLAUTO; 3) SETLCONSTRUCT is scalable and has similar performance compared to SETLPROG.

description: The Chandra X-ray Observatory is providing remarkable new views of massive star-forming regions, revealing all stages in the life cycle of high-mass stars and their effects on their surroundings. We present a Chandra tour of several high-mass star-forming regions, highlighting physical processes that characterize the life of a cluster of high-mass stars, from deeply-embedded cores too young to have established an HII region to superbubbles so large that they shape our views of galaxies. Along the way we see that X-ray observations reveal hundreds of stellar sources powering great HII region complexes, suffused by both hard and soft diffuse X-ray structures caused by fast O-star winds thermalized in wind-wind collisions or by termination shocks against the surrounding media. Finally, we examine the effects of the deaths of high-mass stars that remained close to their birthplaces, exploding as supernovae within the superbubbles that these clusters created. We present new X-ray results on W51 IRS2E and 30 Doradus and we introduce new data on Trumpler 14 in Carina and the W3 HII region complexes W3 Main and W3(OH).

description: Vascular mechanics plays a key role in both health and disease. Therefore, the mechanical properties of vessels have been under study for over a century. This thesis reports research with two computational models designed to better understand vessel mechanics in complex loading scenarios. Numerous methodologies have been utilized to evaluate the mechanical behavior of blood vessels, including distending arterial rings to investigate circumferential behavior, a configuration commonly used in wire myography. We previously used this configuration to experimentally characterize microstructural damage in cerebral arteries that may transpire in clinical procedures and due to trauma. However, due to the complexity of loading, we were not able to quantify strains throughout the vessel experimentally. As a consequence, we were not able to relate microstructural damage with vessel strains in all parts of the vessel. Thus, the aim of the current investigation was to quantify strains throughout the arterial ring by using a computational model. To achieve our goal, we created a finite element (FE) model of the experiment using FEBio. In the model, we observed complex vessel strain distributions along the circumference. Most vessel strains were observed to vary considerably through the wall thickness in regions near the needles, but circumferential strains remained largely constant throughout the ring. In this research, another computational model was constructed to understand the significance of perfusion in cerebral arteries' strain rate dependence. Although many investigators have attempted to characterize the strain rate dependence of arteries experimentally, there has been disagreement in the results. In our previous investigation, our lab observed strain rate dependence in dynamically-loaded middle cerebral arteries (MCAs) in rats. We hypothesized that perfusion was at least partly responsible for the observed behavior and designed a computational model using LS-DYNA to test our hypothesis. As expected, we observed a contribution of perfusion to strain rate dependence in the circumferential and the radial directions. However, it was not sufficient to influence experimentally witnessed axial strain rate dependence.

Measurements of the differential cross section for inclusive charged pion production at mid rapidity and for inclusive neutral pion production at forward rapidity (3.0 < eta < 4.2) as well as the first preliminary result from STAR for the differential cross section for inclusive neutral pion production near mid rapidity are presented. These cross sections are compared to next-to-leading order perturbative QCD calculations and can provide constraints on the pion fragmentation functions. Good agreement between data and pQCD has been found for all three cross sections.

description: Despite being the current "gold standard" for repair of nerve gaps there are downsides to autografts, including: limited donor tissue availability, and size mismatch between graft and nerve stumps. Nerve conduits are a promising alternative to autografts. They act as guidance cues for the regenerating axons and allow for tension-free bridging. Separately, it has been shown that localized delivery of neurotrophic factors (NTF) such as NGF (nerve growth factor)/GDNF (Glial cell line derived neurotrophic factor)/FK506 (Tacrolimus) can enhance axon growth. This dissertation describes the design of a novel drug delivery apparatus integrated with a PLGA (poly lactic-co-glycolic acid) or PTFE (polytetrafluoroethylene)-based nerve conduit for controlled local delivery of neurotrophic factors. We have fabricated and verified the efficacy of a novel biocompatible nerve conduit to (1) continuously deliver a therapeutic dose of small molecules or growth factors locally, and (2) improve the degree of peripheral nerve regeneration and functional recovery following a peripheral nerve injury. First, a drug dosage curve was acquired to determine the minimum in vitro concentration for optimal neurite outgrowth of DRG (dorsal root ganglion) cells. Next, drug delivery devices were designed to release sufficient neurotrophins to enhance neurite outgrowth and finally tested in vitro and in vivo. Mathematical models were developed to identify the optimal design of the nerve conduit in both dimension and drug dosage with respect to final drug concentration at the proximal nerve stump. The mathematical diffusion model was verified using a microfluidic setup of the device. The drug delivery nerve guides were able to release adequate concentration of NGF/GDNF/FK506 for 28 days at concentrations (0.1-10 ng/mL) that were shown to enhance DRG neurite growth. Following these tests, drug-releasing nerve conduits were implanted across 15-mm sciatic nerve gaps in a rat model or 10-mm sciatic nerve gaps in a mouse model, where they demonstrated significant nerve regeneration in vivo as compared to empty nerve conduits. This drug delivery nerve guide can release drugs for extended periods of time and enhance axon growth in vitro and in vivo and has the potential to improve nerve regeneration following a peripheral nerve injury.

description: Vacuum structures of supersymmetric (SUSY) Yang-Mills theories in $1+1$ dimensions are studied with the spatial direction compactified. SUSY allows only periodic boundary conditions for both fermions and bosons. By using the Born-Oppenheimer approximation for the weak coupling limit, we find that the vacuum energy vanishes, and hence the SUSY is unbroken. Other boundary conditions are also studied, especially the antiperiodic boundary condition for fermions which is related to the system in finite temperatures. In that case we find for gaugino bilinears a nonvanishing vacuum condensation which indicates instanton contributions.

description: Fuzzing and symbolic execution are popular techniques for finding vulnerabilities and generating test-cases for programs. Fuzzing, a blackbox method that mutates seed input values, is generally incapable of generating diverse inputs that exercise all paths in the program. Due to the path-explosion problem and dependence on SMT solvers, symbolic execution may also not achieve high path coverage. A hybrid technique involving fuzzing and symbolic execution may achieve better function coverage than fuzzing or symbolic execution alone. In this paper, we present Munch, an open source framework implementing two hybrid techniques based on fuzzing and symbolic execution. We empirically show using nine large open-source programs that overall, Munch achieves higher (in-depth) function coverage than symbolic execution or fuzzing alone. Using metrics based on total analyses time and number of queries issued to the SMT solver, we also show that Munch is more efficient at achieving better function coverage.

description: Adaptiveness is a key principle in information processing including statistics and machine learning. We investigate the usefulness of adaptive methods in the framework of asymptotic binary hypothesis testing, when each hypothesis represents asymptotically many independent instances of a quantum channel, and the tests are based on using the unknown channel and observing outputs. Unlike the familiar setting of quantum states as hypotheses, there is a fundamental distinction between adaptive and non-adaptive strategies with respect to the channel uses, and we introduce a number of further variants of the discrimination tasks by imposing different restrictions on the test strategies. The following results are obtained: (1) We prove that for classical-quantum channels, adaptive and non-adaptive strategies lead to the same error exponents both in the symmetric (Chernoff) and asymmetric (Hoeffding, Stein) settings. (2) The first separation between adaptive and non-adaptive symmetric hypothesis testing exponents for quantum channels, which we derive from a general lower bound on the error probability for non-adaptive strategies; the concrete example we analyze is a pair of entanglement-breaking channels. (3)We prove, in some sense generalizing the previous statement, that for general channels adaptive strategies restricted to classical feed-forward and product state channel inputs are not superior in the asymptotic limit to non-adaptive product state strategies. (4) As an application of our findings, we address the discrimination power of an arbitrary quantum channel and show that adaptive strategies with classical feedback and no quantum memory at the input do not increase the discrimination power of the channel beyond non-adaptive tensor product input strategies.

Computer-Aided Approaches to Enhance Systematic Review Development

description: Medical knowledge learned in medical school can become quickly outdated given the tremendous growth of the biomedical literature. It is the responsibility of medical practitioners to continuously update their knowledge with recent, best available clinical evidence to make informed decisions about patient care. However, clinicians often have little time to spend on reading the primary literature even within their narrow specialty. As a result, they often rely on systematic evidence reviews developed by medical experts to fulfill their information needs. At the present, systematic reviews of clinical research are manually created and updated, which is expensive, slow, and unable to keep up with the rapidly growing pace of medical literature. This dissertation research aims to enhance the traditional systematic review development process using computer-aided solutions. The first study investigates query expansion and scientific quality ranking approaches to enhance literature search on clinical guideline topics. The study showed that unsupervised methods can improve retrieval performance of a popular biomedical search engine (PubMed). The proposed methods improve the comprehensiveness of literature search and increase the ratio of finding relevant studies with reduced screening effort. The second and third studies aim to enhance the traditional manual data extraction process. The second study developed a framework to extract and classify texts from PDF reports. This study demonstrated that a rule-based multipass sieve approach is more effective than a machine-learning approach in categorizing document-level structures and iv that classifying and filtering publication metadata and semistructured texts enhances the performance of an information extraction system. The proposed method could serve as a document processing step in any text mining research on PDF documents. The third study proposed a solution for the computer-aided data extraction by recommending relevant sentences and key phrases extracted from publication reports. This study demonstrated that using a machine-learning classifier to prioritize sentences for specific data elements performs equally or better than an abstract screening approach, and might save time and reduce errors in the full-text screening process. In summary, this dissertation showed that there are promising opportunities for technology enhancement to assist in the development of systematic reviews. In this modern age when computing resources are getting cheaper and more powerful, the failure to apply computer technologies to assist and optimize the manual processes is a lost opportunity to improve the timeliness of systematic reviews. This research provides methodologies and tests hypotheses, which can serve as the basis for further large-scale software engineering projects aimed at fully realizing the prospect of computer-aided systematic reviews.

Optics

description: Optics is an old topic in physical science and engineering. Historically, bulky materials and components were dominantly used to manipulate light. A new hope arrived when Maxwell unveiled the essence of electromagnetic waves in a micro perspective. On the other side, our world recently embraced a revolutionary technology, metasurface, which modifies the properties of matter-interfaces in subwavelength scale. To complete this story, diffractive optic fills right in the gap. It enables ultrathin flat devices without invoking the concept of nanostructured metasurfaces when only scalar diffraction comes into play. This dissertation contributes to developing a new type of digital diffractive optic, called a polychromat. It consists of uniform pixels and multilevel profile in micrometer scale. Essentially, it modulates the phase of a wavefront to generate certain spatial and spectral responses. Firstly, a complete numerical model based on scalar diffraction theory was developed. In order to functionalize the optic, a nonlinear algorithm was then successfully implemented to optimize its topography. The optic can be patterned in transparent dielectric thin film by single-step grayscale lithography and it is replicable for mass production. The microstructures are 3?m wide and no more than 3?m thick, thus do not require slow and expensive nanopatterning techniques, as opposed to metasurfaces. Polychromat is also less demanding in terms of fabrication and scalability. The next theme is focused on demonstrating unprecedented performances of the diffractive optic when applied to address critical issues in modern society. Photovoltaic efficiency can be significantly enhanced using this optic to split and concentrate the solar spectrum. Focusing through a lens is no news, but we transformed our optic into a flat lens that corrects broadband chromatic aberrations. It can also serve as a phase mask for microlithography on oblique and multiplane surfaces. By introducing the powerful tool of computation, we devised two imaging prototypes, replacing the conventional Bayer filter with the diffractive optic. One system increases light sensitivity by 3 times compared to commercial color sensors. The other one renders the monochrome sensor a new function of high-resolution multispectral video-imaging.

Optical response of highly reflective film used in the water Cherenkov muon veto of the XENON1T dark matter experiment

description: The XENON1T experiment is the most recent stage of the XENON Dark Matter Search, aiming for the direct detection of Weakly Interacting Massive Particles (WIMPs). To reach its projected sensitivity, the background has to be reduced by two orders of magnitude compared to its predecessor XENON100. This requires a water Cherenkov muon veto surrounding the XENON1T TPC, both to shield external backgrounds and to tag muon-induced energetic neutrons through detection of a passing muon or the secondary shower induced by a muon interacting in the surrounding rock. The muon veto is instrumented with $84$ $8"$ PMTs with high quantum efficiency (QE) in the Cherenkov regime and the walls of the watertank are clad with the highly reflective DF2000MA foil by 3M. Here, we present a study of the reflective properties of this foil, as well as the measurement of its wavelength shifting (WLS) properties. Further, we present the impact of reflectance and WLS on the detection efficiency of the muon veto, using a Monte Carlo simulation carried out with Geant4. The measurements yield a specular reflectance of $\approx100\%$ for wavelengths larger than $400\,$nm, while $\approx90\%$ of the incoming light below $370\,$nm is absorbed by the foil. Approximately $3-7.5\%$ of the light hitting the foil within the wavelength range $250\,$nm $\leq λ\leq 390\,$nm is used for the WLS process. The intensity of the emission spectrum of the WLS light is slightly dependent on the absorbed wavelength and shows the shape of a rotational-vibrational fluorescence spectrum, peaking at around $λ\approx 420\,$nm. Adjusting the reflectance values to the measured ones in the Monte Carlo simulation originally used for the muon veto design, the veto detection efficiency remains unchanged. Including the wavelength shifting in the Monte Carlo simulation leads to an increase of the efficiency of approximately $0.5\%$.
