description: Solar energy development has to be based on unique innovative technologies. Its role in the power
industry of the future will be defined by the potentialities in the field of development and practical use of new
physical principals, manufacturing techniques, materials and designs to create solar energy converters of high
competitive ability. In this work, the most perspective directions for the development of the silicon based solar power
have been overviewed and the basic manufacturing technologies for photoelectric converters and semiconductor
materials designed at VIESH have been presented that include: chloride-free solar-grade silicon manufacturing
technology, matrix solar cell technology providing an efficiency of 25% to 30% for conversion of concentrated solar
radiation, thermal and laser radiation, silicon solar module encapsulation technology providing the enhanced power
performance and life span of up to 50 years, new solar radiation concentration methods making it possible to achieve
uniform solar cell irradiation, for concentration ratios ranging from 50 to 100.

description: In many species, sucrose en route out of the leaf migrates from photosynthetically active mesophyll cells into the phloem down its concentration gradient via plasmodesmata, i.e., symplastically. In some of these plants the process is entirely passive, but in others phloem sucrose is actively converted into larger sugars, raffinose and stachyose, and segregated (trapped), thus raising total phloem sugar concentration to a level higher than in the mesophyll. Questions remain regarding the mechanisms and selective advantages conferred by both of these symplastic loading processes. Here we present an integrated model - including local and global transport and the kinetics of oligomerization - for passive and active symplastic loading. We also propose a physical model of transport through the plasmodesmata. With these models, we predict that: 1) relative to passive loading, oligomerization of sucrose in the phloem, even in the absence of segregation, lowers the sugar content in the leaf required to achieve a given export rate and accelerates export for a given concentration of sucrose in the mesophyll; and 2) segregation of oligomers and the inverted gradient of total sugar content can be achieved for physiologically reasonable parameter values, but even higher export rates can be accessed in scenarios in which polymers are allowed to diffuse back into the mesophyll. We discuss these predictions in relation to further studies aimed at the clarification of loading mechanisms, fitness of active and passive symplastic loading, and potential targets for engineering improved rates of export.

description: Screen-printed Al-BSF silicon solar cells have dominated the PV market for decades. Their long-term success is based on a low-complexity cell architecture and a robust production sequence. The full-area rear contact allows a simple and effective one-dimensional current flow pattern in the base resulting in high fill factors. Some of the successor technologies of this simple but yet successful cell architecture, i.e. PERL and IBC solar cells, have a significantly higher process and pattern complexity.
This presentation discusses a cell structure with an architecture very similar to the classical Al-BSF solar cell but with a higher efficiency potential. This is achieved by substituting the full-area doped back surface region by a passivated contact scheme consisting of a tunnel oxide covered by a heavily doped silicon film, called TOPCon. The current champion efficiency of 24.9% (Voc = 719 mV) on n-type silicon shows that this structure has a high potential while keeping the process effort low and the current flow pattern simple. The very high fill factor of 83.4% results from both, the very low recombination and transport losses caused by this contact scheme. This presentation will give a detailed overview on the ongoing improvement and up-scaling of the TOPCon technology.

description: We study coherent optics in topological insulator surface states with broken time-reversal symmetry and develop a theory for the dynamical Hall effect driven by intense electromagnetic field. The influence of optical Stark effect enters as nonlinear dependence on the optical field in the resulting Faraday $θ_F$ and Kerr $θ_K$ rotations. This nonlinear correction is found to decrease $θ_F$ with the strength of the A.C. electric field, whereas $θ_K$ exhibits a non-monotonic behavior. We also assess the effects of relaxation and dephasing on the Hall and magneto-optical responses when the frequency detuning is comparable to the inverse lifetime of the conduction electrons.

description: We developed a new architecture of crystalline solar cell, based on an ultrathin silicon membrane,
taking advantage of the technology of porous silicon.
The architecture consists of a macro-porous membrane, offering deeply textured surface, capable to efficiently
capture the impinging light, absorbed it in the porous structure, and delivering the photo-generated carriers to
contacts deposited at the extreme of the ultra-thin semiconductor layer.
The new method of realization of the ultra-thin cut from a silicon wafer, is based on the possibility to etch macroporous
structures at the silicon surface, by using the proper regime, to obtain nano-porous etching underneath it, and
from this obtain very thin membrane.
The cell was measured in dark and light condition. The rectifying junction appears as not jet optimized, nevertheless
the cell showed a very large current collection under AM1.5G, evidence of the excellent scattering process induced
by the porous structure, and of the optimal passivation achieved.

description: A $(d,h)$-decomposition of a graph $G$ is an ordered pair $(D, H)$ such that $H$ is a subgraph of $G$ of maximum degree at most $h$ and $D$ is an acyclic orientation of $G-E(H)$ with maximum out-degree at most $d$. In this paper, we prove that for $l \in \{5, 6, 7, 8, 9\}$, every planar graph without $4$- and $l$-cycles is $(2,1)$-decomposable. As a consequence, for every planar graph $G$ without $4$- and $l$-cycles, there exists a matching $M$, such that $G - M$ is $3$-DP-colorable and has Alon-Tarsi number at most $3$. In particular, $G$ is $1$-defective $3$-DP-colorable, $1$-defective $3$-paintable and 1-defective 3-choosable. These strengthen the results in [Discrete Appl. Math. 157~(2) (2009) 433--436] and [Discrete Math. 343 (2020) 111797].

description: In this work the fabrication of two-terminal tandem-solar cell using Perovskite/Si stacked structure is
reported and discussed. In principle this configuration permits to obtain an higher conversion efficiency than single c-
Si junction. While Perovskite cell is realized as top cell, a-Si:H/c-Si heterojunction is used as a bottom cell. The
realization process consists in the fabrication of Glass/FTO/c-TiO2/n-TiO2/CH3NH3PbI3/Spiro-OMeTAD/ITO top
cell, coupled to an ITO/a-Si:H/c-Si/back reflector/Al heterojunction bottom cell. ITO layer is used as a common
electrode for both top and bottom cell. Preliminary results show the feasibility of the tandem cell reaching Voc value
as high as 1.650mV. Numerical simulations is performed to estimate the limitation and the potential of this tandem
structure.

description: This paper gives a theoretical formulation of the electromagnetic response of the quasi-two-dimensional (Q2D) crystals suitable for investigation of optical activity and polariton modes. The response to external electromagnetic field is described by current-current response tensor $Π_{μν}$ calculated by solving the Dyson equation in the random phase approximation (RPA), where current-current interaction is mediated by the photon propagator $D_{μν}$. The irreducible current-current response tensor $Π^0_{μν}$ is calculated from the {\em ab initio} Kohn-Sham (KS) orbitals. The accuracy of $Π^0_{μν}$ is tested in the long wavelength limit where it gives correct Drude dielectric function and conductivity. The theory is applied to the calculation of optical absorption and conductivity in pristine and doped single layer graphene and successfully compared with previous calculations and measurements.

description: Curating research data to ensure it is findable, accessible, interoperable and reusable (FAIR) is gaining increasing importance in engineering sciences. ing.grid – FAIR Data Management in Engineering Sciences is a Diamond Open Access journal that provides a publishing platform for this field. As this field is being established, scientific discussion is of vital importance. Today, peer review hides much of the scientific discussion from the community and the public. In contrast, ing.grid uses an open peer review process that shows reviews, author responses and editor comments alongside the submitted preprints. By bringing the peer review process into the open, ing.grid ensures transparency and accountability and engages the relevant community. The hybrid open peer review concept is put into practice using the Janeway preprint server and journal platforms: After submission via the preprint repository, reviewers, editors, authors and community members post comments. The review comments are specially flagged. Once manuscripts are accepted, they are sent to the journal through a custom-built interface and typesetting. Finally, they are published as peer reviewed articles. ing.grid relies on the support of the publishing services provided by the University and State Library at Technical University of Darmstadt (Germany). The library facilitates the TUjournals press site for scholar-led Diamond Open Access journals. This cooperation allows ing.grid to draw on the library’s cataloguing and long term archiving experience. Moreover, common effort is made to develop a knowledge graph representing the journal. This will lead to improved discovery of published research and the transparency of interconnections between different contributions.

description: Consider three normalised cuspidal eigenforms of weight $2$ and prime level $p$. Under the assumption that the global root number of the associated triple product $L$-function is $+1$, we prove that the complex Abel-Jacobi image of the modified diagonal cycle of Gross-Kudla-Schoen on the triple product of the modular curve $X_0(p)$ is torsion in the corresponding Hecke isotypic component of the Griffiths intermediate Jacobian. The same result holds with the complex Abel-Jacobi map replaced by its étale counterpart. As an application, we deduce torsion properties of Chow-Heegner points associated with modified diagonal cycles on elliptic curves of prime level with split multiplicative reduction. The approach also works in the case of composite square-free level.

description: We study the extent to which very bright (-23.0 < MUV < -21.75) Lyman-break selected galaxies at redshifts z~7 display detectable Lya emission. To explore this issue, we have obtained follow-up optical spectroscopy of 9 z~7 galaxies from a parent sample of 24 z~7 galaxy candidates selected from the 1.65 sq.deg COSMOS-UltraVISTA and SXDS-UDS survey fields using the latest near-infrared public survey data, and new ultra-deep Subaru z'-band imaging (which we also present and describe in this paper). Our spectroscopy has yielded only one possible detection of Lya at z=7.168 with a rest-frame equivalent width EW_0 = 3.7 (+1.7/-1.1) Angstrom. The relative weakness of this line, combined with our failure to detect Lya emission from the other spectroscopic targets allows us to place a new upper limit on the prevalence of strong Lya emission at these redshifts. For conservative calculation and to facilitate comparison with previous studies at lower redshifts, we derive a 1-sigma upper limit on the fraction of UV bright galaxies at z~7 that display EW_0 > 50 Angstrom, which we estimate to be < 0.23. This result may indicate a weak trend where the fraction of strong Lya emitters ceases to rise, and possibly falls between z~6 and z~7. Our results also leave open the possibility that strong Lya may still be more prevalent in the brightest galaxies in the reionization era than their fainter counterparts. A larger spectroscopic sample of galaxies is required to derive a more reliable constraint on the neutral hydrogen fraction at z~7 based on the Lya fraction in the bright galaxies.

description: We have fabricated Si-doped InAs/GaAs quantum dot solar cells (QDSCs) and investigated the
difference in the QDSC properties by controlling density and methods of Si doping. The employed methods for Si
doping are (1) direct-doping into InAs QDs and (2) -doping into GaAs spacer layers. The open-circuit voltage (VOC)
is increased with increasing the Si doping density under the 1 sun solar irradiation and also with increasing the light
concentration. These features suggest that the increase in VOC is ascribed to carrier filling of the QD states.
Improvement of the minority carrier lifetime was also observed by the Si doping, which is most likely due to the
passivation of the recombination centers. This result is consistent with the improvement of the diode ideality factor
extracted from the relationship between the VOC and the light concentration ratio. Both doping methods exhibit
similar effects on these charactaristics. As a results, it is implied that Si doping can fill the QD states as well as
photofilling by light concentration.

Auf der Basis einer Literaturrecherche wird in dieser Arbeit das hierfür relevante Wissen ermittelt und dargelegt. Nachfolgend wird der Wissensstand von 1.-Klasse-Lehrpersonen anhand von sechs Interviews ergründet. Dabei interessiert es, über welches praktische Wissen sie verfügen. Die Analyse der Transkripte bringt zum Vorschein: Einerseits verfügen die interviewten Lehrpersonen in Teilbereichen über beachtenswerte Kenntnisse. Andererseits wird deutlich, dass sie tendenziell zu wenig wissen, um einer Rechenschwäche gezielt entgegenwirken zu können.

description: We give two new examples of non-hyperelliptic curves whose Ceresa cycles have torsion images in the intermediate Jacobian. For one of them, the central value of the $L$-function of the relevant motive is non-vanishing and the Ceresa cycle is torsion in the Griffiths group, consistent with the conjectures of Beilinson and Bloch. We speculate on a possible explanation for the existence of these torsion Ceresa classes, based on some computations with cyclic Fermat quotients.

description: Nuclear matter under extreme conditions can be investigated in ultra-relativistic heavy-ion collisions. The measurement of transverse momentum distributions and yields of identified particles is a fundamental step in understanding collective and thermal properties of the matter produced in such collisions. The ALICE Experiment results on identified charged hadron production are presented for pp collisions at \sqrt{s} = 0.9, 2.76 and 7 TeV and for Pb-Pb collisions at \sqrt{s_{NN}} = 2.76 TeV. Spectral shapes, production yields and nuclear modification factors are shown and compared to previous experiments and Monte Carlo predictions. The spectral shapes in Pb-Pb collisions indicate a strong increase of the radial flow velocity with respect to RHIC energies, which in hydrodynamic models is expected as a consequence of the increasing particle density. The observed suppression of high transverse momentum particles in central Pb-Pb collisions provides evidence for strong parton energy loss in the hot and dense medium.

description: We demonstrate a procedure for quantifying efficiency gains that treats resistive, recombinative, and optical losses on
an equal footing. For this we apply our Conductive Boundary (CoBo) model as implemented in the Quokka cell simulator. The
generation profile is calculated with a novel analytical light trapping model. This model parametrizes the measured reflection spectra
and is capable of turning the experimental case gradually into an ideal Lambertian scheme. Simulated and measured short circuit
current densities agree for our 21.2%-efficient screen-printed PERC cell and for our 23.4%-efficient ion-implanted laser-processed
IBC cell. For the loss analysis of these two cells we set all experimentally accessible control parameters (e.g. saturation current
densities, sheet resistances, and carrier lifetimes) one at a time to ideal values. The efficiency gap to the ultimate limit of 29% is
thereby fully explained in terms of individual improvements and in terms of their respective synergistic effects. This approach allows
comparing loss structures of different types of solar cells, e.g. PERC and IBC cells.

The kink structure around 70 meV in the $σ$ band, which is caused by electron coupling to the E2g phonon mode, is shifted to higher binding energy by ~3.5 meV in Mg(10)B2 and the shift is not affected by superconducting transition. These results serve as the benchmark for investigations of isotope effects in known, unconventional superconductors and newly discovered superconductors where the origin of pairing is unknown.

description: Silicon-tin alloy nanocrystals were successfully synthetized by laser ablation in liquid media technique.
This study underlines the feasibility of nanocrystals with a bandgap lower than the one of bulk silicon that remains
friendly with the silicon technology. The nanocrystals reveal a bandgap about 0.81eV due to the bandgap engineering
generated by the alloy, which allow absorption at longer wavelengths. Hybrid solar cells with silicon-tin nanocrystals
mixed with a conjugated polymer polythieno[3,4-b]thiophenebenzodithiophene, namely PTB7, as active layer were
fabricated to underline and characterize the photovoltaic properties resulting from the nanocrystals. The enhanced
absorption results in a better short-circuit current observed for hybrid solar cells with silicon-tin nanocrystals
compared to devices without nanocrystals. The open-circuit voltage is also enhanced, which underlines the benefic
behaviour of a heterojunction inside the active layer. Furthermore the laser ablation in liquid media technique enables
a surface engineering in situ during the fabrication process which allows stable photovoltaic properties.

description: We study a free fermion model where two sets of non-commuting non-projective measurements stabilize area-law entanglement scaling phases of distinct topological order. We show the presence of a topological phase transition that is of a different universality class than that observed in stroboscopic projective circuits. In the presence of unitary dynamics, the two topologically distinct phases are separated by a region with sub-volume scaling of the entanglement entropy. We find that this entanglement transition is well identified by a combination of the bipartite entanglement entropy and the topological entanglement entropy. We further show that the phase diagram is qualitatively captured by an analytically tractable non-Hermitian model obtained via post-selecting the measurement outcome. Finally we introduce a partial-post-selection continuous mapping, that uniquely associates topological indices of the non-Hermitian Hamiltonian to the distinct phases of the stochastic measurement-induced dynamics.

description: This article presents two area/latency optimized gate level asynchronous full adder designs which correspond to early output logic. The proposed full adders are constructed using the delay-insensitive dual-rail code and adhere to the four-phase return-to-zero handshaking. For an asynchronous ripple carry adder (RCA) constructed using the proposed early output full adders, the relative-timing assumption becomes necessary and the inherent advantages of the relative-timed RCA are: (1) computation with valid inputs, i.e., forward latency is data-dependent, and (2) computation with spacer inputs involves a bare minimum constant reverse latency of just one full adder delay, thus resulting in the optimal cycle time. With respect to different 32-bit RCA implementations, and in comparison with the optimized strong-indication, weak-indication, and early output full adder designs, one of the proposed early output full adders achieves respective reductions in latency by 67.8, 12.3 and 6.1 %, while the other proposed early output full adder achieves corresponding reductions in area by 32.6, 24.6 and 6.9 %, with practically no power penalty. Further, the proposed early output full adders based asynchronous RCAs enable minimum reductions in cycle time by 83.4, 15, and 8.8 % when considering carry-propagation over the entire RCA width of 32-bits, and maximum reductions in cycle time by 97.5, 27.4, and 22.4 % for the consideration of a typical carry chain length of 4 full adder stages, when compared to the least of the cycle time estimates of various strong-indication, weak-indication, and early output asynchronous RCAs of similar size. All the asynchronous full adders and RCAs were realized using standard cells in a semi-custom design fashion based on a 32/28 nm CMOS process technology.

description: Surface plasmon resonance of metallic nanoparticles can be applied to photovoltaic devices. In this
report, we propose Tin nanoparticles (Sn NPs) for crystalline silicon solar cells. Sn NPs have been fabricated easily
on different substrates by thermal evaporator for the Sn thicknesses: 5 nm, 10 nm and 15 nm. Various thicknesses and
thermal annealing processes can determine the average size, the shape and the surface coverage of Sn NPs on Si
wafer. For the optical properties of Sn NPs, reflectance spectra decrease after Sn NPs deposition, but we saw the
strong absorption of Sn NPs below wavelength 500 nm. In the end, Sn NPs were successfully integrated with c-Si
solar cells. Photocurrent at short wavelengths is declined due to the absorption of Sn NPs. After the annealing process
of Sn NPs, we can increase the efficiency of c-Si solar cells.

description: Die vorliegende Masterarbeit beschäftigt sich mit der Frage, inwiefern onkologisch erkrankte Kinder nach einer längeren Schulabsenz bei der Reintegration in die Regelschule durch Schulische Heilpädagog*innen unterstützt werden können. Im ersten Teil der Arbeit wird eine Zusammenstellung der aktuellen Literatur zur Thematik präsentiert. Zudem wurden Leitfadeninterviews mit drei ehemals betroffenen Personen sowie einer Lehrperson geführt. Die dadurch gewonnenen Informationen werden mittels einer qualitativen Inhaltsanalyse nach Mayring (2015) ausgewertet. Die Resultate zeigen, dass viele der in der Literatur beschriebenen Unterstützungsmassnahmen von den Befragten als fördernd angesehen werden. Die Befragten konnten aus eigener Erfahrung noch weitere Unterstützungsmöglichkeiten für betroffene Kinder nennen. Basierend auf den Erkenntnissen aus der Inhaltsanalyse der Interviews sowie der Literaturrecherche werden Handlungsempfehlungen für begleitende Schulische Heilpädagog*innen formuliert. Das Ermöglichen von «Normalität» stellt einen der zentralen Gelingensfaktoren für die Reintegration dar.

description: We address the evaluation of energy selective contacts for hot carrier solar cells through numerical
modeling of heterostructures based on III-V materials with a resonant energy level that acts as the energy selective
level. A self-consistent code is developed using the transfer matrix formalism and the effective mass approximation
to model the behavior of a double resonant tunneling barrier under various conditions. The application of a
polarization to the structure is found to significantly reduce the transmission of the double barrier through the
resonant level due to the breaking of the symmetry, and we show that such effect can be offset by using an
asymmetrical double barrier to recover a transmission close to one under a specific electric bias. The behavior of such
double barrier is also studied when hot electrons transit from the emitter side to the collector side, by modeling the
variation of the current voltage characteristic for different electrons’ temperatures. A negative differential resistance
is observed and the variations of some specific features of the curve are physically interpreted, giving important
insight on the expected behavior of a hot carrier solar cell using double resonant tunneling barriers as selective
contact.

description: The influence of Aluminum Oxide (Al1-xOx) films grown on two types of silicon micro wire (Si-MW) substrates
by thermal atomic layer deposition (ALD) technique as a passivation layer was investigated, compared to the one grown on
conventional flat wafer substrate. When the growth rate of the Al1-xOx film became closed to the ideal growth rate (0.11
nm/cycle), the Al1-xOx film has then shown good-passivation effect and were found to be uniformly deposited. Compared to
the samples grown on flat substrate and the Si-MW substrate fabricated using ICP-dry etching technique, the Al1-xOx film
deposited on the Si-MW substrate using Deep-RIE technique, blessed us with implied Voc of 0.646 V after annealing. We
investigated implied Voc of Al1-xOx films and reflectance properties for Si-MW substrates with various wire-array sizes ((1)D=2
um, P=4 um, (2)D=3 um, P=5 um, (3)D=5 um, P=8 um, (4)D=7 um, P=10 um, (5)D=10 um, P=13 um). We found that the
relation between implied Voc and reflectance properties for each of wire array size of Si-MW substrates, is in a trade-off.
Van der Waals metal-semiconductor junction: weak Fermi level pinning enables effective tuning of Schottky barrier

description: Two-dimensional (2D) semiconductors have shown great promise in (opto)electronic applications. However, their developments are limited by a large Schottky barrier (SB) at the metal-semiconductor junction (MSJ), which is difficult to tune by using conventional metals due to the strong Fermi level pinning (FLP) effect. Here we show that, this problem can be overcome by using 2D metals, which are bounded with 2D semiconductors through van der Waals (vdW) interaction. This success relies on a weak FLP at the vdW MSJ, which is attributed to the suppression of metal-induced gap states. Consequently, the SB becomes tunable and can vanish with proper 2D metals (e.g. H-NbS2). This work not only offers new insights into the fundamental properties of heterojunctions, but also uncovers great potential of 2D metals in device applications.

is proposed for deposition of anti-scratch and oleofobic protective coatings coatings for providing long-term clearness

down- and upconversion. Special in-line coater was constructed for continuous modification of solar cells and cover
glasses or foils. Our technology is also suitable for application on large-scale photovoltaic devices. The very wide
commercial potential of proposed technology will also give the industry direct tool for efficient, ecology friendly and
high quality fabrication of complex protective, photonic and nanoelectronic structures on different kinds of rigid and
flexible solar cells.
High magnetic field neutron stars and magnetars in binary systems

description: Situation with highly magnetized neutron stars in binary systems is not yet certain. On the one hand, all best studied magnetars seem to be isolated objects. On the other, there are many claims based on model-dependent analysis of spin properties or/and luminosity of neutron stars in X-ray binaries in favour of large fields. In addition, there are a few results suggesting a magnetar-like activity of neutron stars in close binary systems. Most of theoretical considerations do not favour even existence, not speaking about active decay, of magnetar-scale fields in neutron stars older than $\sim10^6$~yrs. However, alternative scenarios of the field evolution exist. I provide a brief review of theoretical and observational results related to the presence of neutron stars with large magnetic field in binaries and discuss perspectives of future studies.

description: A four-year sky survey with the use of the eROSITA telescope on board the Spektr-RG observatory will provide the best coverage in the soft (0.5-2 keV) and standard (2-10 keV) X-ray ranges, both in terms of sensitivity and angular resolution. We have analysed the possibility of detecting various types of isolated neutron stars with eROSITA. Among already known objects, eROSITA will be able to detect more than 160 pulsars, 21 magnetars, 7 central compact objects, all seven sources of the Magnificent Seven, and two other X-ray isolated neutron stars during the four-year survey mission.

description: Front-surface textures contribute both reduced reflection loss and light trapping to increase optical
absorption in thin wafer crystalline silicon solar cells. We investigated the impact of the modulated surface textures
that are composed of nanotextures for reducing reflection and microtextures for enhancing light trapping.
Electromagnetic wave simulations show that modulated surface textures shows sufficient photocurrent generation,
comparable to double-sided textures that exhibits light trapping close to Lambertian limit. Our finding indicates that
the modulated surface textures would be a promising approach for efficient photon management in thin wafer solar
cells. Simulation results show that optical design of modulated photonic nanostructure is critical for efficient light
trapping.
Pedestrians in static crowds are not grains, but game players

description: The local navigation of pedestrians amid a crowd is generally believed to involve no anticipation beyond (at best) the avoidance of the most imminent collisions. We show that current models rooted in this belief fail to reproduce some key features experimentally evidenced when a dense static crowd is crossed by an intruder. We identify the missing ingredient as the pedestrians' ability to plan their motion well beyond the next interaction, whence they may accept to move towards denser regions for a short time. To account for this effect, we introduce a minimal model based on mean-field game theory, which proves remarkably successful in replicating the aforementioned observations as well as other daily-life situations involving collective behaviour in dense crowds, such as partial metro boarding. This demonstrates the ability of game approaches to capture the anticipatory effects at play in operational crowd dynamics.
