description: NeMeSys is a NUMA-aware graph pattern processing engine, which leverages intelligent resource management for energy adaptive processing. With modern server systems incorporating an increasing amount of main memory, we can store graphs and compute analytical graph algorithms like graph pattern matching completely in-memory. Such server systems usually contain several powerful multiprocessors, which come with a high demand for energy. We demonstrate, that graph patterns can be processed in given performance constraints while saving energy, which would be wasted without proper controlling.

description: The uncertainty in the absolute value of the fluorescence yield is still one of the main contributions to the total error in the reconstruction of the primary energy of ultra-energetic air showers using the fluorescence technique. A significant number of experimental values of the fluorescence yield have been published in the last years, however reported results are given very often in different units (photons/MeV or photons/m) and for different wavelength intervals. In this work we present a comparison of available results normalized to its value in photons/MeV for the 337 nm band at 800 hPa and 293 K. The conversion of photons/m to photons/MeV requires an accurate determination of the energy deposited by the electrons in the field of view of the experimental setup. We have calculated the energy deposition for each experiment by means of a detailed Monte Carlo simulation including when possible the geometrical details of the particular setup. Our predictions on deposited energy, as well as on some geometrical factors, have been compared with those reported by the authors of the corresponding experiments and possible corrections to the fluorescence yields are proposed.

description: We report on the experimental demonstration of the broadband "trapped rainbow" in the visible range using arrays of adiabatically tapered optical nano waveguides. Being a distinct case of the slow light phenomenon, the trapped rainbow effect could be applied to optical signal processing, and sensing in such applications as spectroscopy on a chip, and to providing enhanced light-matter interactions. As an example of the latter applications, we have fabricated a large area array of tapered nano-waveguides, which exhibit broadband "trapped rainbow" effect. Considerable fluorescence enhancement due to slow light behavior in the array has been observed.

description: My thesis traces the provenance of select works from the Aaron M. and Clara Weitzenhoffer Collection, bequeathed to the Fred Jones Jr. Museum of Art at The University of Oklahoma. This collection, which was the largest donation of Impressionist paintings and works on paper to a public university, lacks provenance documentation in the field’s literature. The recent litigations of the looted painting Shepherdess Bringing in Sheep or La Bergère Rentrant des Moutons (1886) by Camille Pissarro with the Jewish heir Léone-Noëlle Meyer stressed the need for the Fred Jones Jr. Museum of Art to renew and disclose the provenance of the rest of the collection. By closely examining four artworks’ origins, from original artists to the bequeathed objects within the Weitzenhoffer estate in 2000, my thesis will aim to solidify provenance documentation and further highlight the inherent requisite to change archival standards. I will trace the circulation of the following artworks: Mary Cassatt’s 1901 portrait, Sara in a Dark Bonnet Tied Under Her Chin, Edgar Degas’ 1885 pastel, Dancer at the Barre, Camille Pissarro’s 1894 landscape, Apple Trees in a Meadow at Éragny, and Claude Monet’s 1879 landscape painting, Riverbank at Lavacourt. My research will rely on Getty Research Institute catalogue materials narrating the selected artworks from the Weitzenhoffer Collection. In addition, I will compare the actual provenance materials from the Fred Jones Jr. Museum of Art with personal archival research to uncover historical trajectories and improve provenance research techniques.

flow past a sphere

description: We present an implementation of the finite-element method with hierarchical basis functions of arbitrary order for simulating incompressible steady-state fluid flow governed by Navier-Stokes equations (NSE). To verify the proposed formulation, we solved a problem of the fluid flow around a rigid sphere considering different velocity magnitudes. For a low-Reynolds-number flow the result coincides with the analytical solution for the Stokes flow, while for a higher Reynolds number a vortex is formed behind the sphere. The developed framework can be used to study the fluid flow in contact interfaces between solids with rough surfaces (e.g. in fractures) and compare the effect of the model describing the fluid flow (Reynolds, Stokes, or full NSE) on the transmissivity of these interfaces. The development is undertaken in MoFEM.
Initial Algebra Semantics for Cyclic Sharing Tree Structures

description: Terms are a concise representation of tree structures. Since they can be naturally defined by an inductive type, they offer data structures in functional programming and mechanised reasoning with useful principles such as structural induction and structural recursion. However, for graphs or "tree-like" structures - trees involving cycles and sharing - it remains unclear what kind of inductive structures exists and how we can faithfully assign a term representation of them. In this paper we propose a simple term syntax for cyclic sharing structures that admits structural induction and recursion principles. We show that the obtained syntax is directly usable in the functional language Haskell and the proof assistant Agda, as well as ordinary data structures such as lists and trees. To achieve this goal, we use a categorical approach to initial algebra semantics in a presheaf category. That approach follows the line of Fiore, Plotkin and Turi's models of abstract syntax with variable binding.

description: This research was conducted to investigate the Islamic Education Teachers’ (IET) readiness
in conducting 21st-century learning style in primary schools of Kuala KangsarDistrict. The
research was conducted by employing a quantitative approach with a survey method, which
involved 140 respondents of IET serving in primary schools of Kuala KangsarDistrict. The
data obtained were analyzed using the descriptive analysis to explain the readiness of
teachers in conducting 21st-century learning. The findings revealed that the teachers had a
high level of readiness (M=3.8, SD=0.5). In conclusion, the IET in the district of Kuala
Kangsaris ready to accept and conduct 21st-century learning as the current method of teaching
and learning in education. The teachers were identified to have high readiness to fulfill the
desire for executing 21st-century learning based on the guidelines given by the Malaysian
Ministry of Education. However, the teachers need to be trained and given workshops on the
21st century learning to improve their readiness and effectiveness. This is important as the
teachers are the ones implementing and executing the method in their classroom.
Instructors’ and students’ needs for next generation video in education
Creators: name: Fong, Matthew
Publisher: name: University of British Columbia
Year: 2021

description: As education moves towards a more digital experience, teachers and students are increasingly using video technology. This dissertation is composed of three studies that explored the use of video from both sides of the teaching and learning paradigm: an Instructor study, a Student study, and a Video Highlighting study. In the Instructor study, 16 instructors who teach with video were interviewed. Instructors use video because students are more likely to watch videos before class than read textbooks. Further, using a flipped classroom model and moving lectures into pre-class video enables active learning during class time. However, creating videos is not a trivial task, and there are limited ways that instructors can assess if their students have watched and/or understood the videos. Instructors are eager to leverage digital data from students' video use to generate both aggregate and individual level data about how students are using video for learning. In the Student study, we deployed a custom video player to five cohorts of an undergraduate chemistry class across three years. Students (n=248) used the video player to view nine videos per semester. Data were collected through activity traces generated from logs and a subset of students were interviewed. Students familiarised themselves with the content by watching sequentially and clarified their knowledge by re-watching. When students reviewed a video in preparation for a test, they searched through the video to find what they needed. Students optimised their use of video by spending more time on parts of the videos that were tied to their grades. Finally, in the Video Highlighting study, we introduced a method for highlighting a transcript and a filmstrip series of thumbnails of a video. A controlled laboratory study with 11 students revealed that for search tasks in video, users were able to find previously highlighted parts of video quickly, but transcripts were preferred over the filmstrip highlighting. The use of video in education is continuing to grow. Instructors use video to promote student engagement, yet future work is needed to make video easier to produce, evaluate, search and organise.
Higgs boson decays and production in the left-right twin Higgs model

Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The left-right twin Higgs model predicts one neutral Higgs boson $ϕ_{0}$ and it acquires mass $m_{ϕ_{0}}\sim μ_{r}$ with the $μ$ term, which can be lighter than half the SM-like Higgs boson mass in a portion of parameter space. Thus, the SM-like Higgs boson $h$ can dominantly decay into a pair of light neutral Higgs bosons especially when $m_{h}$ is below the $WW$ threshold. First, we examine the branching ratios of the SM-like Higgs boson decays and find that the new decay mode $h\rightarrow ϕ_{0}ϕ_{0}$ is dominant for the case of $m_{h}>2m_{ϕ_{0}}$. Then we study the production via gluon fusion followed by the decay into two photons or two weak gauge bosons and found that the production rate can be significantly suppressed for some part of parameter space. Finally, we comparatively study the process $γγ\rightarrow h \rightarrow b\bar{b}$ at ILC in the cases of $m_{h}>2m_{ϕ_{0}}$ and $m_{h}<2m_{ϕ_{0}}$, respectively. We find that these predictions can significantly deviated from the SM predictions, e.g., the gluon-gluon fusion channel, in the cases of $m_{h}>2m_{ϕ_{0}}$ and $m_{h}<2m_{ϕ_{0}}$, can be suppressed by about 80% and 45%, respectively. Therefor, it is possible to probe the left-right twin Higgs model via these Higgs boson production processes at the LHC experiment or in the future ILC experiment.

description: We revisit the moduli space approximation to the quantum mechanics of monopoles in N=4 supersymmetric Yang-Mills-Higgs theory with maximal symmetry breaking. Starting with the observation that the set of fermionic zero-modes in N=4 supersymmetric Yang-Mills-Higgs theory can be viewed as two copies of the set of fermionic zero-modes in the N=2 version, we build a model to describe the quantum mechanics of N=4 supersymmetric monopoles, based on our previous paper [1] on the N=2 case, in which this doubling of fermionic zero-modes is manifest throughout. Our final picture extends the familiar result that quantum states are described by differential forms on the moduli space and that the Hamiltonian operator is the Laplacian acting on forms. In particular, we derive a general expression for the total angular momentum operator on the moduli space which differs from the naive candidate by the adjoint action of the complex structures. We also express all the supercharges in terms of (twisted) Dolbeault operators and illustrate our results by discussing, in some detail, the N=4 supersymmetric quantum dynamics of monopoles in a theory with gauge group SU(3) broken to U(1) x U(1).

description: Delsarte showed that for any projective linear code over a finite field of characteristic p with two nonzero Hamming weights w1 < w2 there exist positive integers u and s such that w1 = (p^s)u and w2 = (p^s)(u+1). Moreover, he showed that the additive group of such a code has a strongly regular Cayley graph. Here we show that for any proper regular projective linear code C over a finite Frobenius ring with two integral nonzero homogeneous weights w1 < w2, there is a positive integer d, a divisor of the order of C, and positive integer u such that w1 = du and w2 = d(u+1). In doing so, we give a new proof of the known result that any proper regular projective two-weight code code yields a strongly regular graph. We apply these results to existence questions on two-weight codes.

description: Zero resistance differential states have been observed in two-dimensional electron gases (2DEG) subject to a magnetic field and a strong dc current. In a recent work we presented a model to describe the nonlinear transport regime of this phenomenon. From the analysis of the differential resistivity and the longitudinal voltage we predicted the formation of negative differential resistivity states, although these states are known to be unstable. Based on our model, we derive an analytical approximated expression for the Voltage-Current characteristics, that captures the main elements of the problem. The result allow us to construct an energy functional for the system. In the zero temperature limit, the system presents a quantum phase transition, with the control parameter given by the magnetic field. It is noted that above a threshold value ($B>B_{th}$), the symmetry is spontaneously broken. At sufficiently high magnetic field and low temperature the model predicts a phase with a non-vanishing permanent current; this is a novel phase that has not been observed so far.

Differences can be seen in the large-scale cutoffs of the distributions. Event duration distributions suggest that the scale-free aspects are related to the absence of characteristic scales in the meteorological mesoscale.

description: We calculate the spectrum of elementary excitations in a two-dimensional exciton superfluid in the vicinity of a two-dimensional electron gas. We show that attraction of excitons due to their scattering with free electrons may lead to formation of a roton minimum. The energy of this minimum may go below the ground state energy which manifests breaking of the superfluidity. The Berezinsky-Kosterlitz-Thouless phase transition temperature decreases due to the exciton-exciton attraction mediated by electrons.

description: Processes constitute the major vehicle to support companies to move towards digital business (models). One major application area is smart manufacturing, also referred to as Industrie 4.0. Here, processes connect and integrate machines, actors, sensors, information systems, and business partners, collecting, processing, and exchanging production-relevant data.  This yields manifold benefits such as optimized processing and integrated data analysis.  Designing and implementing such solutions touches and raises many research challenges, including the flexible and robust implementation of distributed process networks and the application and extension of process-oriented data analysis methods. We illustrate these challenges by our own journey from a LEGO-based Industrie 4.0 lab setting to the centurio.work manufacturing orchestration suite.
Shock waves in strongly coupled plasmas

description: Shock waves are supersonic disturbances propagating in a fluid and giving rise to dissipation and drag. Weak shocks, i.e., those of small amplitude, can be well described within the hydrodynamic approximation. On the other hand, strong shocks are discontinuous within hydrodynamics and therefore probe the microscopics of the theory. In this paper we consider the case of the strongly coupled N=4 plasma whose microscopic description, applicable for scales smaller than the inverse temperature, is given in terms of gravity in an asymptotically $AdS_5$ space. In the gravity approximation, weak and strong shocks should be described by smooth metrics with no discontinuities. For weak shocks we find the dual metric in a derivative expansion and for strong shocks we use linearized gravity to find the exponential tail that determines the width of the shock. In particular we find that, when the velocity of the fluid relative to the shock approaches the speed of light $v\to 1$ the penetration depth $\ell$ scales as $\ell\sim (1-v^2)^{1/4}$. We compare the results with second order hydrodynamics and the Israel-Stewart approximation. Although they all agree in the hydrodynamic regime of weak shocks, we show that there is not even qualitative agreement for strong shocks. For the gravity side, the existence of shock waves implies that there are disturbances of constant shape propagating on the horizon of the dual black holes.

description: The insulating ternary oxide YbFe$_2$O$_4$ displays an unusual frustration-driven incommensurate charge-ordering (CO) transition, linked to possible ferroelectricity. Based on high-resolution synchrotron data, we report a detailed structural model showing that the CO phase is an incommensurate charge-density wave and cannot be ferroelectric, since the electrical dipole moments are also incommensurately modulated. The change between continuous and "spotty" helices of scattering at the CO transition is attributed to three-dimensional fluctuations of the direction of the ordering wavevector.

description: The pulmonary system can maintain arterial blood gas homeostasis during exercise in healthy, young adults. However, some endurance athletes demonstrate a significant reduction in arterial oxygenation during exercise, a phenomenon termed exercise-induced arterial hypoxemia (EIAH). EIAH has been previously observed in young adults, and male masters athletes but there are no reports of gas exchange impairment in female masters athletes. It was hypothesized the majority of female masters athletes will develop EIAH during submaximal, near maximal, and maximal treadmill exercise. Pulmonary function was assessed followed by an incremental exercise test to determine maximal O2 uptake (V̇O2max). Participants were instrumented with a radial arterial catheter, an oesophageal balloon-tipped catheter, and temperature probe. Arterial samples were drawn while participants exercised at 60-70, 75, 90-95, and 100% V̇O2max for 2-4 minutes. Participants (n=6, 48-57 years) had an average V̇O2max of 47±2 ml/kg/min (range 40-55 ml/kg/min, 135-186% predicted). During submaximal, near maximal, and maximal exercise the arterial partial pressure of O2 (PaO2) decreased from rest by 14±2 mmHg (range 6-21), 13±4 (range -6-24), and 11±7 mmHg (range -7-21), respectively. The arterial partial pressure of CO2 (PaCO2) decreased from rest by 1.8±1 mmHg (range -2-6), 4±1 mmHg (range 0.3- 8), and 5±2 mmHg (range 2-5) at submaximal, near maximal, and maximal exercise, respectively. There was a reduction in oxyhemoglobin saturation 2.5± 0.3% (range 1.9-3.4) and arterial O2 content 1.2± 0.2 mL O2/100 mL of blood (range 0.7-1.8) at all intensities. Participants with a minimal change to PaCO2 tended to have a greater reduction in PaO2 (r = -0.85, R2 = 0.73, p< 0.05). The alveolar to arterial oxygen (A-aDO2) gradient increased during submaximal (range 7-34 mmHg), near maximal (range 7-47 mmHg) and maximal (range 7-48 mmHg) exercise. The decrease in PaO2 and increased A-aDO2 gradient indicates an inadequate ventilatory response to exercise. There was no relationship between V̇O2max and PaO2. These results suggest that female masters athletes develop EIAH at submaximal and maximal exercise intensities and a high level of aerobic fitness is not a requisite for the development of EIAH.

description: In this paper we consider a novel statistical inverse problem on the Poincaré, or Lobachevsky, upper (complex) half plane. Here the Riemannian structure is hyperbolic and a transitive group action comes from the space of $2\times2$ real matrices of determinant one via Möbius transformations. Our approach is based on a deconvolution technique which relies on the Helgason--Fourier calculus adapted to this hyperbolic space. This gives a minimax nonparametric density estimator of a hyperbolic density that is corrupted by a random Möbius transform. A motivation for this work comes from the reconstruction of impedances of capacitors where the above scenario on the Poincaré plane exactly describes the physical system that is of statistical interest.

description: We report the detection of several emission bands in the CO Fourth Positive Group from comet 103P/Hartley during ultraviolet spectroscopic observations from the Hubble Space Telescope (HST) on 2010 November 4 near the time of closest approach by NASA's EPOXI spacecraft. The derived CO/H2O ratio is 0.15-0.45%, which places 103P among the most CO-depleted comets. Apparently this highly volatile species, whose abundance varies by a factor of ~50 among the comets observed to date, does not play a major role in producing the strong and temporally variable activity in 103P/Hartley. The CO emissions varied by ~30% between our two sets of observations, apparently in phase with the temporal variability measured for several gases and dust by other observers. The low absolute abundance of CO in 103P suggests several possibilities: the nucleus formed in a region of the solar nebula that was depleted in CO or too warm to retain much CO ice, repeated passages through the inner solar system have substantially depleted the comet's primordial CO reservoir, or any CO still in the nucleus is buried below the regions that contribute significantly to the coma.

description: Hash tables are a core data structure in database systems, because they are fundamental for many database operators like hash-based join and aggregation. In recent years, the efficient vectorized implementation using SIMD (Single Instruction Multiple Data) instructions has attracted a lot of attention. Generally, all hash table implementations need to address what happens when collisions occur. In order to do that, the collisions have to be detected first. There are two types of collisions: (i) key duplicates and (ii) hash value duplicates. The second type is more complicated than the first type. In this paper, we investigate linear probing as a heavily applied hash table implementation and we present an extension of the state-of-the-art vectorized implementation with a hardware-supported duplicate or collision detection. For that, we use novel SIMD instructions which have been introduced with Intel’s SIMD instruction set extension AVX-512. As we are going to show, our approach outperforms the state-of-the-art vectorized version for the key handling, but introduces novel challenges for the value handling. We conclude the paper with some ideas how to tackle that challenge.

description: Stream Processing Engines (SPEs) must tolerate the dynamic nature of unbounded data streams and provide means to quickly adapt to fluctuations in the data rate. Many major SPEs however provide very little functionality to adjust the execution of a potentially infinite streaming query at runtime. Each modification requires a complete query restart, which involves an expensive redistribution of the state of a query and may require external systems in order to guarantee correct processing semantics. This results in significant downtime, which increase the operational cost of those SPEs. We present a modification protocol that enables modifying specific operators as well as the data flow of a running query while ensuring exactly-once processing semantics. We provide an implementation for Apache Flink, which enables stateful operator migration across machines, the introduction of new operators into a running query, and changes to a specific operator based on external triggers. Our results on two benchmarks show that migrating operators for queries with small state is as fast as using the savepoint mechanism of Flink. Migrating operators in the presence of large state even outperforms the savepoint mechanism by a factor of more than 2.3. Introducing and replacing operators at runtime is performed in less than 10 s. Our modification protocol demonstrates the general feasibility of runtime modifications and opens the door for many other modification use cases, such as online algorithm tweaking and up-or downscaling operator instances.

description: Topological defects in graphene, dislocations and grain boundaries, are still not well understood despites the considerable number of experimental observations. We introduce a general approach for constructing dislocations in graphene characterized by arbitrary Burgers vectors as well as grain boundaries, covering the whole range of possible misorientation angles. By using ab initio calculations we investigate thermodynamic and electronic properties of these topological defects, finding energetically favorable symmetric large-angle grain boundaries, strong tendency towards out-of-plane deformation in the small-angle regimes, and pronounced effects on the electronic structure. The present results show that dislocations and grain boundaries are important intrinsic defects in graphene which may be used for engineering graphene-based nanomaterials and functional devices.

description: K nearest neighbor search (kNN-Search) is a universal data processing technique and a fundamental operation for word embeddings trained by word2vec or related approaches. The benefits of operations on dense vectors like word embeddings for analytical functionalities of RDBMSs motivate an integration of kNN-Joins. However, kNN-Search, as well as kNN-Joins, have barely been integrated into relational database systems so far. In this paper, we develop an index structure for approximated kNN-Joins working well on high-dimensional data and provide an integration into PostgreSQL. The novel index structure is efficient for different cardinalities of the involved join partners. An evaluation of the system based on applications on word embeddings shows the benefits of such an integrated kNN-Join operation and the performance of the proposed approach.

description: Data Lakes haben sich in der industriellen Praxis als Plattformen für die Speicherung und Analyse aller Arten von (Roh-)daten etabliert. Erweiterte Anforderungen hinsichtlich Governance und Self-Service machen das Metadatenmanagement im Data Lake zum kritischen Erfolgsfaktor. Bisher gibt es dazu jedoch nur wenige wissenschaftliche Arbeiten, es mangelt insbesondere an einer ganzheitlichen Betrachtung zur Konzeption und Realisierung des Metadatenmanagements im Data Lake. Diese Arbeit adressiert das Thema und basiert auf praktischen Erfahrungen aus einem Industriekonzern beim Aufbau eines unternehmensweiten Data Lake. Es werden praktische Anforderungen und Anwendungsbeispiele für das Metadatenmanagement im Data Lake diskutiert und die unterschiedlichen Arten von Metadaten anhand des Praxisbeispiels analysiert. Zur Umsetzung des Metadatenmanagements werden anschießend unterschiedliche IT-Werkzeuge anhand definierter Kriterien analysiert. Das Analyseergebnis zeigt, dass Datenkataloge grundsätzlich die geeignete Werkzeugart darstellen, wobei noch technische Unzulänglichkeiten existieren. Abschließend werden die in der Praxis bestehenden Herausforderungen für ein ganzheitliches Metadatenmanagement im Data Lake zusammengefasst und zukünftige Forschungsbedarfe aufgezeigt.

description: Bei der Einhaltung von Schadstoffwerten nehmen öffentliche Verkehrsmittel eine immer entscheidendere Rolle ein. Daher wird vermehrt darauf geachtet, deren Attraktivität zu erhöhen. Ein wichtiger Punkt hierbei ist die Vorhersagegenauigkeit von Verspätungen zu verbessern, damit Fahrgäste entsprechend planen können. Die aktuell angewandten Ansätze sind häufig ungenau, da sie die zur Verfügung stehenden Daten nicht ausreichend nutzen. In diesem Beitrag stellen wir daher mit TAROT ein System vor, das mittels prädiktiver Analysen die Vorhersagegenauigkeit von Verspätungen verbessert, indem es in den Modellen Verspätungsfortpflanzungen berücksichtigt. Darüber hinaus ist es in der Lage, im Fall einer Störung augenblicklich auf ein besseres Vorhersagemodell umzusteigen und auf sowohl schleichende als auch abrupte Veränderungen automatisch zu reagieren. Die Vorteile dieser Eigenschaften lassen sich in unserem TAROT-Demonstrator anhand von vier repräsentativen Anwendungsszenarien zeigen. Auch wenn sich die gezeigten Szenarien alle auf die Verspätungs-vorhersage von S-Bahnen beziehen, lassen sich die Konzepte von TAROT auch auf viele andere Anwendungsbereiche (z. B. zur Bestimmung von Produktionszeiten in der Industrie 4.0) anwenden.

description: Modern real-time databases follow the same collection-based querying semantics as traditional database systems. Targeting interactive workloads, real-time databases do not only deliver a query’s result upon request, but also produce a continuous stream of informational updates thereafter. In theory, building interactive, reactive, or collaborative applications should thus be simple with collection-based real-time queries as they bridge the gap between traditional database queries over static collections and continuous queries over dynamic data streams. In practice, though, building real-time applications is still considered challenging, since most real-time databases today provide only poor scalability, confusing interfaces for real-time data access, and reduced query expressiveness in comparison to their pull-based counterparts. In this demo, we illustrate that scalability, query expressiveness, and simplicity can go hand-in-hand for modern real-time databases. To this end, we present the social media search app Twoogle which is built on top of Baqend’s real-time query API.

description: Proton hexality is a discrete symmetry that avoids the problem of too fast proton decay in the supersymmetric extension of the standard model. Unfortunately it is inconsistent with conventional grand unification. We show that proton hexality can be incorporated in the scheme of "Local Grand Unification" discussed in the framework of model building in (heterotic) string theory.
