description: In order to extract maximal information from neutron-star merger signals, both gravitational and electromagnetic, we need to ensure that our theoretical models/numerical simulations faithfully represent the extreme physics involved. This involves a range of issues, with the finite temperature effects regulating many of the relevant phenomena. As a step towards understanding these issues, we explore the conditions for $β$-equilibrium in neutron star matter for the densities and temperatures reached in a binary neutron star merger. Using the results from our out-of-equilibrium merger simulation, we consider how different notions of equilibrium may affect the merger dynamics, raising issues that arise when attempting to account for these conditions in future simulations. These issues are both computational and conceptual. We show that the effects lead to, in our case, a softening of the equation of state in some density regions, and to composition changes that affect processes that rely on deviation from equilibrium, such as bulk viscosity, both in terms of the magnitude and the equilibration timescales inherent to the relevant set of reactions. We also demonstrate that it is difficult to determine exactly which equilibrium conditions are relevant in which regions of the matter due to the dependence on neutrino absorption, further complicating the calculation of the reactions that work to restore the matter to equilibrium.

description: The project aims to find traces of the Herodian city wall (‘Second Wall’) in Jerusalem. Since there is no possibility to undertake new excavations within the Old City the project uses geophysical methods. Within two seasons (autumn 2015 and 2016) the 7 m deep sondage underneath the Church of the Redeemer as well as several places at the Muristan, the Cardo, Suqs and of the ‘Via Dolorosa’ have been measured. The first season in 2015 was a pilot study in order to proof the geographical and local measurement conditions and to solve the technical challenges given by the deep and narrow sondage underneath the Church of the Redeemer as well as by a survey in an urban area. The geophysical survey of a historical city as Jerusalem pose some demands which requires new ground penetrating radar (GPR) concepts. The project tried to meet these requirements by the implementation of a unique GPR prototype. The new method has a large impact on the implementation technology of GPR devices leading to simplified electronics and better device performance. In the second season the locations mentioned above have been measured by using the new high sensitive devices.

description: Recent experiments by Larson et al. demonstrate the feasibility of measuring local $dd$ excitations using nonresonant inelastic X-ray scattering (IXS). We establish a general framework for the interpretation where the $dd$ transitions created in the scattering process are expressed in effective one-particle operators that follow a simple selection rule. The different operators can be selectively probed by employing their different dependence on the direction and magnitude of the transferred momentum. We use the operators to explain the presence of nodal directions and the nonresonant IXS in specific directions and planes. We demonstrate how nonresonant IXS can be used to extract valuable ground state information for orbiton excitations in manganite.

A colonial, postcolonial, and existential sense of self-destruction of Igbo characters in the narrative of Chinua Achebe

description: Taking Sartre’s existential theories as a point of departure, this thesis examines the theme of self-destruction as a phase resulting from the loss of identity among Igbo characters, both during and after British colonisation. Mainly concerned with colonialism and its aftermath, this thesis focuses on selected novels by the Nigerian writer, Chinua Achebe, especially Things Fall Apart and Arrow of God, set during the British colonial era, and No Longer at Ease and A Man of the People, set in a post-colonial context. I contend that this theme of self-destruction can not only be examined from colonial/post-colonial perspectives, but also from an existential angle by focusing on the absolute freedom of choice or free will of self-aware characters, who can make and take responsibility for their own decisions, and whose ‘authentic existence’ plays a major role in their decision-making. Consequently, the most important questions explored in this thesis include the following: To what extent can the self-proclaimed superiority of white colonisers over the ‘inferiority’ of colonised blacks lead to the latter’s self-destruction? Moreover, what is the impact of self-awareness on the decisions made by colonised people, which eventually result in their self-destruction? Likewise, how does the representation of self-destruction vary from one character to another? And finally, how can the investigation of self-destruction help colonised people to decolonise their own country and resist the effects of colonisation?

description: Feldforschungen und Aufarbeitung von Grundlagendaten In summer 2016, Uruk (modern Warka) became part of the cultural and natural World Heritage “The Ahwar of Southern Iraq: refuge of biodiversity and the relict landscape of the Mesopotamian cities“. Fieldwork at Uruk was therefore composed of a scientific as well as a management/conservation component. It focused on surveying the suburbs of the ancient town, amending the topographic base through further geodetic and photographic documentation, developing conservation measures, as well as on some emergency conservation activities. All activities were interconnected with the training program “Iraqi-German Expert Forum on Cultural Heritage” (IGEF). At Uruk, for example, modules were offered on the techniques of archaeological fieldwork, the professional documentation and analysis of architectural remains, and on the development of conservation measures. The training components were generously funded by the German Foreign Office. Konservierungen in der Uruk-Warka-Sammlung des Deutschen Archäologischen Instituts an der Universität Heidelberg For the Uruk-Warka-Collection of small finds, stored and used as study collection at the University of Heidelberg, the programme for improvement of the magazines and the conservation of objects was continued in a close cooperation between the University of Heidelberg and the Orient-Department of the German Archaeological Institute.
Quantum Entanglement Capacity with Classical Feedback

description: For any quantum discrete memoryless channel, we define a quantity called quantum entanglement capacity with classical feedback ($E_B$), and we show that this quantity lies between two other well-studied quantities. These two quantities - namely the quantum capacity assisted by two-way classical communication ($Q_2$) and the quantum capacity with classical feedback ($Q_B$) - are widely conjectured to be different: there exists quantum discrete memoryless channel for which $Q_2>Q_B$. We then present a general scheme to convert any quantum error-correcting codes into adaptive protocols for this newly-defined quantity of the quantum depolarizing channel, and illustrate with Cat (repetition) code and Shor code. We contrast the present notion with entanglement purification protocols by showing that whilst the Leung-Shor protocol can be applied directly, recurrence methods need to be supplemented with other techniques but at the same time offer a way to improve the aforementioned Cat code. For the quantum depolarizing channel, we prove a formula that gives lower bounds on the quantum capacity with classical feedback from any $E_B$ protocols. We then apply this formula to the $E_B$ protocols that we discuss to obtain new lower bounds on the quantum capacity with classical feedback of the quantum depolarizing channel.
Identifying low-amplitude pulsating stars through microlensing observations

description: One possibility for detecting low-amplitude pulsational variations is through gravitational microlensing. During a microlensing event, the temporary brightness increase leads to improvement in the signal-to-noise ratio, and thereby better detectability of pulsational signatures in light curves. We explore this possibility under two primary considerations. The first is when the standard point-source and point-lens approximation applies. In this scenario, dividing the observed light curve by the best-fitted microlensing model leads to residuals that result in pulsational features with improved uncertainties. The second is for transit events (single lens) or caustic crossing (binary lens). The point-source approximation breaks down, and residuals relative to a simple best-fitted microlensing model display more complex behavior. We employ a Monte-Carlo simulation of microlensing of pulsating variables toward the Galactic bulge for the surveys of OGLE and of KMTNet. We demonstrate that the efficiency for detecting pulsational signatures with intrinsic amplitudes of $<0.25$ mag during single and binary microlensing events, at differences in $χ^{2}$ of $Δχ^{2} >350$, is $\sim 50-60\%$. The maximum efficiency occurs for pulsational periods $P \simeq 0.1-0.3$ days. We also study the possibility that high-magnification microlensing events of non-radially pulsating stars (NRPs) could be misinterpreted as planetary or binary microlensing events. We conclude that small asymmetric features around lightcurve peaks due to stellar pulsations could be misdiagnosed with crossing (or passing close to) small caustic curves.

Niemeier. The recent campaigns of 2014 to 2016 led by K. Sporn aimed at a general study of the sanctuary’s area and infrastructure to find answers to the following questions: Can we surely identify the sanctuary of Kalapodi as the oracle of Abai – and where is the town of Abai to be located then? Is it an urban, suburban or even an extra urban sanctuary? Is it possible to determine the sanctuary’s boundaries and how are sacred and profane spaces distributed throughout its area?

description: Chaenopsidae   9) Stathmonotus. Stathmonotus stahli (Evermann & Marsh), was described based on specimens collected in Puerto Rico. Subsequently Stathmonotus tekla Nichols was described from Sand Key, Florida. Springer (1955) considered them subspecies and Hastings & Springer (1994) reported that they differ in number of segmented caudal-fin rays (11-13, modally 12 in stahli versus 10-12, modally 11 in tekla), number of dorsalfin spines (41-45, modally 43 in stahli versus 39-44, modally 42 in tekla) and number of precaudal vertebrae (17-19, modally 18 in stahli versus 16-19, modally 17 in tekla). These features reliably distinguish the forms and we consider them both as valid species.
 10) Chaenopsis. Chaenopsis alepidota (Gilbert) was described based on specimens from the northern Gulf of California collected aboard the Albatross. Subsequently Chaenopsis alepidota californiensis Böhlke was described based on three specimens collected from Isla Catalina off the coast of southern California. The latter subspecies was recognized based primarily on its having more rays in the dorsal and anal fins (total for all elements 95-97, mean = 96 versus 89-94, mean = 91.3), although Böhlke concluded that it “seems that little differentiation has taken place” (Böhlke, 1957, p. 97). These meristic characters follow the expected patterns of phenotypic variation as a consequence of the significantly colder environmental temperatures experienced by the populations in California. As noted by Böhlke (1957), populations of species from colder areas generally have more fin-ray elements (Jordan’s rule; Jordan, 1891; Lindsey, 1988) calling into question the significance of the diagnostic features of these forms of C. alepidota. A recent study on their genetics (Bernardi et al., 2003) found that the two forms are reciprocally monophyletic (albeit based on relatively small sample sizes), but also found evidence of recent gene flow among them. In addition, the percent sequence divergence in the mitochondrial control region between California and Gulf populations is low (1.87%) compared to disjunct sister species with similar distributions (Dawson et al., 2006). In the absence of additional morphological data and analysis of genetic variation across their distributions, we do not recommend elevation of the population from California to species status.

description: Although it is well recognized that gamma-ray burst (GRB) afterglows are obscured and reddened by dust in their host galaxies, the wavelength-dependence and quantity of dust extinction are still poorly known. Current studies on this mostly rely on fitting the afterglow spectral energy distributions (SEDs) with template extinction models. The inferred extinction (both quantity and wavelength-dependence) and dust-to-gas ratios are often in disagreement with that obtained from dust depletion and X-ray spectroscopy studies. We argue that this discrepancy could result from the prior assumption of a template extinction law. We propose an analytical formula to approximate the GRB host extinction law. With the template extinction laws self-contained, and the capability of revealing extinction laws differing from the conventional ones, it is shown that this is a powerful approach in modeling the afterglow SEDs to derive GRB host extinction.

Electromagnetic induction using powerlines

Publisher: name: University of British Columbia
Year: 2010

description: The possibility of obtaining information about subsurface conductivity structure using powerlines as a source has been investigated. Powerlines have been modelled as purely inductive sources over a layered earth. Solutions for the field components produced by an elevated straight line source of current over a layered earth are presented. Exact solutions are in the form of a (inverse) Fourier transform. These expressions are evaluated numerically using Fast Fourier Transform (FFT) algorithms. Preliminary interpretations of magnetic field data gathered in the vicinity of a powerline have been made using these expressions. Emphasis at this stage is on forward model results. For the case of a bent line of current the computation of exact solutions becomes costly, so that approximate solutions are used employing complex image theory. Image theory results agree with exact solution results throughout the quasi-static range, except at distances less than the order of a skin depth from the source. Effects due to lateral inhomogeneities in a homogeneous half space were modelled with the use of an electrolytic tank. A cylindrical wave analogue model was used to study the effect of a rectangular structure embedded in a homogeneous half space. Inphase and quadrature measurements of the total field are obtained.

description: Today we have a solid, if incomplete, physical picture of how inertia is created in the standard model. We know that most of the visible baryonic `mass' in the Universe is due to gluonic back-reaction on accelerated quarks, the latter of which attribute their own inertia to a coupling with the Higgs field -- a process that elegantly and self-consistently also assigns inertia to several other particles. But we have never had a physically viable explanation for the origin of rest-mass energy, in spite of many attempts at understanding it towards the end of the nineteenth century, culminating with Einstein's own landmark contribution in his Annus Mirabilis. Here, we introduce to this discussion some of the insights we have garnered from the latest cosmological observations and theoretical modeling to calculate our gravitational binding energy with that portion of the Universe to which we are causally connected, and demonstrate that this energy is indeed equal to mc^2 when the inertia m is viewed as a surrogate for gravitational mass.

description: WP4 was aimed at developing eco-innovative, collectively-based and gender-sensitive waste prevention and management strategies to reduce the amount of municipal waste production by developing reuse, recycling, and selective collection of waste in cities with high levels of tourism.

The present deliverable is the product of several tasks (4.1, 4.2, 4.3 and 4.5) from WP4 and was based on the input of WP2 (Operationalizing urban metabolism) and WP3 (Mobilization of stakeholders) that gave the basis for the strategies’ definition. WP6 in particular tasks 6.3 (implementation of selected measures) and 6.4 (monitoring systems) enabled to capitalize the lessons learnt during the implementation phase, and to identify the possible fine-tuning to make more efficient the measures that have been implemented.

D4.1 “URBAN-WASTE prevention and management strategies and guidelines for implementation” provides the description of each pilot case in terms of tourism characteristics, waste management, stakeholders, the process of selection of measures and the results and feedback from their implementation.

It provides also a thorough description of the waste prevention and management measures designed, defining their objectives and targets, type of waste addressed, operational steps to be taken, the potential solutions for the financing of the measure, guidelines for monitoring and set up evaluation indicators. In addition, each description of measure compiles mains results obtained and key points identified during the implementation phase in the different pilot cases. Its whole content constitutes guidelines for policy makers.

description: Three body systems where one of the bodies is ejected without escaping the binary system have previously been studied in various restricted forms. However, none of these studies dwells on the problem in a general setting. Thus, to study this phenomenon qualitatively, we try to expand this problem's scope to unequal mass systems and generalize them by considering various configurations of fixed initial points with precisely calculated initial velocities, some zero velocity models, and some optimized models. We will see the use of terminology similar to the previous studies done in this domain, but incorporate different analytical and evaluation methods.

By taking into account of the ionized impurity scattering we calculate Green's functions self-consistently and examine the effects of ionized impurity scattering on electron densities and currents. For nano-scale Si wires, it is found that, due to the impurity scattering, the local density of state profiles loose it's interference oscillations as well as is broaden and shifted. In addition, the impurity scattering gives rise to a different transconductance as functions of temperature and impurity scattering strength when compared with the transconductance without impurity scattering.

The iconographical analysis which is nearly completed deals with both traditional Egyptian and ‘international’ motifs depicted on the gold sheets and how they were integrated in the context of Egyptian art at the end of the 18th dynasty. Furthermore, various technical aspects concerning the backings of the gold sheets which consist of different layers of leather, textile, gesso and resins were investigated. In addition, the composition of the gold was examined by portable XRF-analysis resulting in the identification of six different material groups which broadly overlap with groups formed on grounds of iconographical results.

description: Resonant soft X-ray scattering with photon energies near the O K and the Cu L3 edges was used to study charge ordering in the system La_{1.8-x}Eu_{0.2}Sr_xCuO_4 as a function of temperature for x = 0.125 and 0.15. From the superstructure diffraction intensities a charge ordering with a doping dependent wave vector is derived which is in this system well below the transition temperature of the low-temperature tetragonal phase but well above the onset of spin ordering. This indicates that charge ordering is the primary driving force for the formation of stripe-like phases in two-dimensional doped cuprates. Analysis of the lineshape of the scattered intensity as a function of photon energy yields evidence for a high hole concentration in the stripes.

The aim of this season was to complete the documentation of the blocks that had been reused in the temple house of Nectanebos II. The blocks appear to originate from at least two different buildings. The first building was a small barque station built by Queen Hatshepsut in the early part of her reign for the processional barque of Khnum. The second building was founded by Thutmosis I and finished or enlarged by Thutmosis II. Both buildings originally stood to the west of the main temple of Khnum, in the area later occupied by the temple house of Nectanebos II.

description: The amplitude-dependent frequency of the oscillations, termed \emph{nonisochronicity}, is one of the essential characteristics of nonlinear oscillators. In this paper, the dynamics of the Rossler oscillator in the presence of nonisochronicity is examined. In particular, we explore the appearance of a new fixed point and the emergence of a coexisting limit-cycle and quasiperiodic attractors. We also describe the sequence of bifurcations leading to synchronized, desynchronized attractors and oscillation death states in the coupled Rossler oscillators as a function of the strength of nonisochronicity and coupling parameters. Further, we characterize the multistability of the coexisting attractors by plotting the basins of attraction. Our results open up the possibilities of understanding the emergence of coexisting attractors, and into a qualitative change of the collective states in coupled nonlinear oscillators in the presence of nonisochronicity.

description: We study the six-particle amplitude in planar $\mathcal{N} = 4$ super Yang-Mills theory in the double scaling (DS) limit, the only nontrivial codimension-one boundary of its positive kinematic region. We construct the relevant function space, which is significantly constrained due to the extended Steinmann relations, up to weight 13 in coproduct form, and up to weight 12 as an explicit polylogarithmic representation. Expanding the latter in the collinear boundary of the DS limit, and using the Pentagon Operator Product Expansion, we compute the non-divergent coefficient of a certain component of the Next-to-Maximally-Helicity-Violating amplitude through weight 12 and eight loops. We also specialize our results to the overlapping origin limit, observing a general pattern for its leading divergence.

description: The Sloan Digital Sky Survey has been instrumental in obtaining a homogeneous sample of the rare AM CVn stars: mass-transferring binary white dwarfs. As part of a campaign of spectroscopic follow-up on candidate AM CVn stars from the Sloan Digital Sky Survey, we have obtained time-resolved spectra of the g=20.2 candidate SDSS J155252.48+320150.9 on the Very Large Telescope of the European Southern Observatory. We report an orbital period of 3376.3+/-0.3 s, or 56.272+/-0.005 min, based on an observed `S-wave' in the helium emission lines of the spectra. This confirms the ultracompact nature of the binary. Despite its relative closeness to the orbital period minimum for hydrogen-rich donors, there is no evidence for hydrogen in the spectra. We thus classify SDSS J1552 as a new bona fide AM CVn star, with the second-longest orbital period after V396 Hya (P=65.5 min). The continuum of SDSS J1552 is compatible with either a blackbody or helium atmosphere of 12,000-15,000 K. If this represents the photosphere of the accreting white dwarf, as is expected, it puts the accretor at the upper end of the temperature range predicted by thermal evolution models. This suggests that SDSS J1552 consists of (or formerly consisted of) relatively high-mass components.

description: The season 2015 focused on the reconstruction of the ancient landscape in the northwestern Nile Delta by means of auger core drillings. In particular, two questions were addressed: Firstly, was there an ancient branch of the Nile flowing roughly in the area of two modern canals? This seemed to be indicated by the linear distribution of settlements, predominantly of the Roman and Late Roman age. Secondly, what is the precise extent of an ancient lagoon, which was first identified by the discovery of peat layers in the 1980s?

description: The method of an effective potential is used to investigate the possible types of evolution of vacuum shells in the Friedman-Schwarzschild world. Such shells are assumed to emerge during phase transitions in the early Universe. The possible global geometries are constructed for the Friedman- Schwarzschild worlds. Approximate solutions to the equation of motion of a vacuum shell have been found. The conditions under which the end result of the evolution of the vacuum shells under consideration is the formation of black holes and wormholes with baby universes inside have been found. The interior of this world can be a closed, flat, or open Friedman universe.

description: The field work of 2015/16 on Bigge, the little island between the two dams of Aswan south of the Philae temple complex, focussed on the examination of two Nubian villages: Balle and Bigge. Both villages date back between 1912 and 1933 and were left about 25 years ago and have since then been prone to massive decay through climatic circumstances as well as vandalism and illicit digging. The villages’ vernacular architecture consists of ca. 30 houses. In addition, pathways and commonly used spaces, cultivable land and two cemeteries in the island’s centre can still easily be traced.

description: Blue Large-Amplitude Pulsators (BLAPs) are a recently discovered class of pulsating star, believed to be proto-white dwarfs, produced by mass stripping of a red giant when it has a small helium core. An outstanding question is why the stars in this class of pulsator seem to form two distinct groups by surface gravity, despite predictions that stars in the gap between them should also pulsate. We use a binary population synthesis model to identify potential evolutionary pathways that a star can take to become a BLAP. We find that BLAPs can be produced either through common envelope evolution or Roche lobe overflow, with a Main Sequence star or an evolved compact object being responsible for the envelope stripping. The mass distribution of the inferred population indicates that fewer stars would be expected in the range of masses intermediate to the two known groups of pulsators, suggesting that the lack of observational discoveries in this region may be a result of the underlying population of pre-white dwarf stars. We also consider metallicity variation and find evidence that BLAPs at $Z = 0.010$ (half-Solar) would be pulsationally unstable and may also be more common. Based on this analysis, we expect the Milky Way to host around 12000 BLAPs and we predict the number density of sources expected in future observations such as the Legacy Survey of Space and Time at the Vera Rubin Observatory.

Development of tidal energy generation modelling using Morecambe Bay as a case study under different environmental, storage and demand scenarios.
Creators: name: Baker, Simon
Publisher: name: Lancaster University
Year: 2021

description: Electricity generation is a major source of greenhouse gas emissions. Renewable energy mitigates those emissions but poses different problems for the use of the power. This project examines the potential of using a barrage across Morecambe Bay to capture tidal range energy. The tidal system for a specific location is complex and requires multiple levels of robust detailed modelling. The optimum barrage operational parameter values (e.g. generating starting head and turbine speed) vary with the height of the tide. They are also influenced by the design and should be adjusted whenever the design changes. Using 0-D modelling, the energy from real tides can be modelled effectively by applying a set of linear functions to relate the operational parameters to the tidal range. The function coefficients were determined via an optimisation process, specific to each new design, to maximise the generated energy. The timing of electricity generation is dictated by the tide with little scope for adjustment. Electricity cannot be stored and is effectively lost if not needed. To store all the surplus energy from the barrage would require a dedicated facility on a similar scale to the barrage itself and is deemed impractical. With electricity usage patterns expected to change as the UK transitions to a low carbon economy, the solution is perhaps one of energy balancing in combination with storage and conversion to different energy carriers. At a global level the barrage addresses sea-level rise by generating large amounts of green energy. At a local level the barrage can mitigate the threat of increased flooding and can preserve the tidal range to help protect the inter-tidal zone. It is difficult to value all the aspects of a barrage with confidence and to reliably balance the costs of building a barrage against not building it. The environment plays a crucial part in this assessment and must be incorporated into the performance estimates of the barrage at all stages of the design.

description: We demonstrate that single crystals of methylammonium lead bromide (MAPbBr3) could be grown directly on vertically aligned carbon nanotube (VACNT) forests. The fast-growing MAPbBr3 single crystals engulfed the protogenetic inclusions in the form of individual CNTs, thus resulting in a three-dimensionally enlarged photosensitive interface. Photodetector devices were obtained, detecting low light intensities (~20 nW) from UV range to 550 nm. Moreover, a photocurrent was recorded at zero external bias voltage which points to the plausible formation of a p-n junction resulting from interpenetration of MAPbBr3 single crystals into the VACNT forest. This reveals that vertically aligned CNTs can be used as electrodes in operationally stable perovskite-based optoelectronic devices and can serve as a versatile platform for future selective electrode development.

description: The X-ray binary 4U 1626−67 consists of a 7.7 s pulsar in a 41-minute orbit around a white dwarf donor. Chandra/HETGS observations have revealed strong disklines of H-like neon and oxygen (Schulz et al. 2008; Schulz et al., in prep.). These features challenge our current understanding of the system, as they require a significantly higher inclination (~38°) than was previously thought possible, suggesting a carbon-oxygen-neon or oxygen-neon-magnesium composition for the white dwarf companion. Here we present results from a series of Chandra/LETGS observations, designed to further constrain these features and to obtain upper limits on carbon emission

Strong effect of weak diffusion on scalar turbulence at large scales

description: Passive scalar turbulence forced steadily is characterized by the velocity correlation scale, $L$, injection scale, $l$, and diffusive scale, $r_d$. The scales are well separated if the diffusivity is small, $r_d\ll l,L$, and one normally says that effects of diffusion are confined to smaller scales, $r\ll r_d$. However, if the velocity is single scale one finds that a weak dependence of the scalar correlations on the molecular diffusivity persists to even larger scales, e.g. $l\gg r\gg r_d$ \cite{95BCKL}. We consider the case of $L\gg l$ and report a counter-intuitive result -- the emergence of a new range of large scales, $L\gg r\gg l^2/r_d$, where the diffusivity shows a strong effect on scalar correlations.

description: It is proposed that the propagation of light in disordered photonic lattices can be harnessed as a random projection that preserves distances between a set of projected vectors. This mapping is enabled by the complex evolution matrix of a photonic lattice with diagonal disorder, which turns out to be a random complex Gaussian matrix. Thus, by collecting the output light from a subset of the waveguide channels, one can perform an embedding from a higher-dimension to a lower-dimension space that respects the Johnson-Lindenstrauss lemma and nearly preserves the Euclidean distances. It is discussed that distance-preserving random projection through photonic lattices requires intermediate disorder levels that allow diffusive spreading of light from a single channel excitation, as opposed to strong disorder which initiates the localization regime. The proposed scheme can be utilized as a simple and powerful integrated dimension reduction stage that can greatly reduce the burden of a subsequent neural computing stage.
