description: We propose an interferometric method to measure Z2 topological invariants of time-reversal invariant topological insulators realized with optical lattices in two and three dimensions. We suggest two schemes which both rely on a combination of Bloch oscillations with Ramsey interferometry and can be implemented using standard tools of atomic physics. In contrast to topological Zak phase and Chern number, defined for individual 1D and 2D Bloch bands, the formulation of the Z2 invariant involves at least two Bloch bands related by time- reversal symmetry which one has keep track of in measurements. In one of our schemes this can be achieved by the measurement of Wilson loops, which are non-Abelian generalizations of Zak phases. The winding of their eigenvalues is related to the Z2 invariant. We thereby demonstrate that Wilson loops are not just theoretical concepts but can be measured experimentally. For the second scheme we introduce a generalization of time-reversal polarization which is continuous throughout the Brillouin zone. We show that its winding over half the Brillouin zone yields the Z2 invariant. To measure this winding, our protocol only requires Bloch oscillations within a single band, supplemented by coherent transitions to a second band which can be realized by lattice-shaking.

description: ABSTRACTTHE RESEARCH PROBLEMThe concept of justice is an integral part of every democratic society. Whatexactly it means in any age is always the subject of debate but there is nodoubt that it exists. The aspiration to achieve justice is timeless, transcendinghistory and national borders and acknowledged by some of the most influentialtexts in UK history: The Magna Carta, in 1215, The American Constitution in 1787,The Great Reform Act in 1867, the Universal Declaration of Human Rights in1948, The Human Rights Act in 1998. (1) The UKSC is the means by which thisaspiration is secured: the bricks and mortar and golden robes, are all the physicalmanifestation of a national aspiration to be governed justly and in accordancewith the rule of law. It is the highest point of arbitration between the individualand the state. Its rulings reflecting the constant tensions between competinginterests, shaping the relationship between the state and those it seeks togovern. This Masters Study explores the interface between the aspiration forjustice, the intangible artefact of the rule of law, and the architectural designof its physical space : a UK Supreme Court building, hereafter UKSC. It asks thequestion what is the appropriate artefact to give physical expression to thepresence of the intangible cultural artefact the rule of law?

description: Fast and efficient data management is one of the demanding technologies of todays aspect. This paper proposes a system which makes the working procedures of present manual system of storing and retrieving huge citizens information of Bangladesh automated and increases its effectiveness. The implemented search methodology is user friendly and efficient enough for high speed data retrieval ignoring spelling error in the input keywords used for searching a particular citizen. The main concern in this research is minimizing the total searching time for a given keyword. This can be done if we can pre-establish the idea of getting the data belonging to the searching keyword. The primary and secondary key-code generated by the Double Metaphone Algorithm for each word is used to establish that idea about the word. This algorithm is used for creating the map of the original database, through which the keyword is matched against the data.

description: We present experiments in which an ultra-cold sample of ammonia molecules is released from an electrostatic trap and recaptured after a variable time. It is shown that, by performing adiabatic cooling before releasing the molecules and adiabatic re-compression after they are recaptured, we are able to observe molecules even after more than 10 ms of free expansion. A coherent measurement performed during this time will have a statistical uncertainty that decreases approximately as the inverse of the square root of the expansion time. This offers interesting prospects for high-resolution spectroscopy and precision tests of fundamental physics theories.

The TESs formed from a bilayer of 40 nm of Mo and 106 nm of Au showed transition temperatures of about 320 mK, higher than identical TESs with a MoCu bilayer which is consistent with a reduced electron transmission coefficient between the bilayer films. We report measurements of thermal conductance in the 200 nm thick silicon nitride SiNx support structures at this temperature, TES dynamic behaviour and current noise measurements.

description: In the majority of mammals, gestation length is relatively consistent and seldom varies by more than 3%. In a few species, females can adjust gestation length by delaying the development of the embryo after implantation. Delays in embryonic development allow females to defer the rising energetic costs of gestation when conditions are unfavourable, reducing the risk of embryo loss. Dispersal in mammals that breed cooperatively is a period when food intake is likely to be suppressed and stress levels are likely to be high. Here we show that pregnant dispersing meerkats (Suricata suricatta), which have been aggressively evicted from their natal group and experience weight loss and extended periods of social stress, prolong their gestation by means of delayed embryonic development. Repeated ultrasound scans of wild, unanaesthetised females throughout their pregnancies showed that pregnancies of dispersers were on average 6.3% longer and more variable in length (52-65 days) than those of residents (54-56 days). The variation in dispersers shows that, unlike most mammals, meerkats can adapt to stress by adjusting their pregnancy length by up to 25%. By doing so, they potentially rearrange the costs of gestation during adverse conditions of dispersal and enhance offspring survival.

description: L'esperienza più completa della libertà, per Hannah Arendt, rappresenta la conditio sine qua non della vita umana, e risiede nell'azione, nella possibilità di agire che si attualizza in atti e discorsi. È per questo che il totalitarismo, caratterizzato dai fenomeni del lavoro servile e dei campi di concentramento, dalla totale negazione e distruzione della facoltà umana della libertà, è la manifestazione del "male" nel mondo, un male senza precedenti nella storia dell'umanità.

description: The implementation of a quantum computer requires a qubit-specific measurement capability to read-out the final state of a quantum system. The model of spin dependent tunneling followed by charge readout has been highly successful in enabling spin qubit experiments in all-electrical, semiconductor based quantum computing. As experiments grow more sophisticated, and head towards multiple qubit architectures that enable small scale computation, it becomes important to consider the charge read-out overhead. With this in mind, Reilly et al. demonstrated a gate readout scheme in a GaAs double quantum dot that removed the need for an external charge sensor. This readout, which achieved sensitivities of order me/$\sqrt(Hz)$, was enabled by using a resonant circuit to probe the complex radio-frequency polarisability of the double quantum dot. However, the ultimate performance of this technology and the noise sources that limit it remain to be determined. Here, we investigate a gate-based readout scheme using a radio-frequency resonant circuit strongly coupled to a double quantum at the corner states of a silicon nanowire transistor. We find a significantly improved charge sensitivity of 37 $μ$e/$\sqrt(Hz)$. By solving the dynamical master equation of the fast-driven electronic transitions we quantify the noise spectral density and determine the ultimate charge and phase sensitivity of gate-based read-out. We find comparable performance to conventional charge sensors and fundamental limits of order ne/$\sqrt(Hz)$ and $μ$rad/$\sqrt(Hz)$, with the gate-based sensor improving on standard detection for certain device parameters. Our results show that, especially in state-of-the-art silicon qubit architectures, charge detection by probing the complex polarisability has advantages in terms of reducing the readout overhead but also in terms of the absolute charge sensitivity.

Plasmid Instability: Measurement and Use in Antimicrobial Action

description: The discovery of antibiotics in the early 20th century revolutionised medicine, but quickly bacteria began to demonstrate resistance to these agents. Antibiotic resistance is still on the increase, and soon, if this trend continues, bacterial infections may not be treatable with antibiotics. In an effort to prevent this occurring, the search for novel antibiotics is under way and new antibiotic targets are being considered. One target that has not been studied in depth is the partitioning systems of bacterial plasmids. Disruption of plasmid partition would prevent effective plasmid inheritance, which, in the case of resistance plasmids, would render the host cell antibiotic sensitive.The aim of this study was to determine whether plasmid partitioning is a viable target for a new antibiotic. A series of plasmids that contained genetically altered partitioning systems was used, which provided a range of plasmid stabilities. The plasmids all conferred antibiotic resistance on the host cell, allowing the effect of plasmid instability on a population grown in the presence of antibiotics to be determined.Several different methods of cell culture were used. Simple batch culture experiments allowed the observation that few plasmid-free cells were produced from cells containing plasmids that had a functional system. In contrast, plasmids containing a faulty system were found to be rapidly lost from the host cells. Steady-state chemostat culture was used to provide a simple model of a clinical infection. The formation of equilibria between plasmid-free and plasmid-bearing cells was observed, and the cultures contained a large proportion of plasmid-free cells when the experiments involved unstable plasmids. The slow growth rate of cultures in the chemostat was seen to dramatically affect the inheritance of plasmids relying on random distribution.Finally, cultures were subjected to washout in order to determine their maximum specific growth rate (µmax). While the results from these experiments are not entirely conclusive, there is a strong indication that the growth rate of cultures containing unstable plasmids grown in the presence of antibiotics is reduced.

The interest of this approach for photovoltaic applications is finally demonstrated by overcoming the integrated absorption of an optimized single pattern membrane through the introduction of a proper pseudo disordered perturbation.

Immigration, Race, and Local Media in the Midlands: 1960-­?1985

Subjects: V214 - English history

description: The passing of the Television Act in 1954 introduced commercial television to British screens for the first time; ITV was formed as a network of regional channels that broadcast content aimed specially at the regions they served. The arrival of regional television also coincided with mass immigration from Britain’s former colonies, a significant proportion of which settled in the Midlands. Scholars of both twentieth-century British history and media history have tended to underplay regional variation. There is a growing but small field of historians who have examined race and media in the same frame but even they have generally not acknowledged the important role of local and regional media in shaping the public response to post-war immigration. This study addresses this absence by examining depictions of immigrants on ATV, ITV’s regional Midlands channel, from 1960 to 1985, focusing primarily on ATV’s news programme through a series of case studies, as well as the production of Here and Now, an ethnic minority arts and culture magazine programme broadcast by ATV (later Central Television) throughout the 1980s. It also examines the previously underexplored role of the local press in the formation of public responses to immigration, highlighting significant links between different forms of local and regional media in post-war Britain by arguing that ATV was, at times, influenced by local press reporting of immigration. ATV and the local press played a crucial role in forming local responses to immigration within the region, one that differed at times to that of the national press, television news and current affairs programming. Unlike the national television news, which reported immigration from a national perspective, ATV broadcast local content which focused specifically on local issues, for example the impact of immigration on local services, employment and housing. This content also crucially provided images of immigrants within the audience’s towns, neighbourhoods and streets. Despite the large immigrant community in the Midlands during the period, ATV failed to properly represent black and Asian people. In doing so, ATV played an important role in defining the boundaries of exclusion and inclusion within Midlands communities. A comparison of regional and national television news and current affairs programming also indicates that ATV understood neutrality differently than the BBC and ITV, often resulting in far more negative representations of race and immigration. By examining the role of local and regional media in public responses to post-war immigration, this study adds depth to our existing understanding of the uneven development of race relations in post-war Britain.

description: Per María Zambrano il lungo periodo dell'esilio dalla Spagna, dal 1939 al 1984, è stato «qualcosa di sacro» di «ineffabile»; una «circostanza» alla quale non poteva rinunciare, perché l'esiliato è «una condizione ineludibile della vita umana». L'esiliato vive senza raggiungere uno «stare» e rimane ai margini della storia. Questa dimensione ontologica dell'esilio non appare dissimile da quella della riflessione politico-esistenziale di Hannah Arendt che la sua origine ebraica fu perseguitata dal nazismo e fuggì dalla Germania nel 1993. Per Arendt la condizione dell'apolide consiste nell'annullamento di qualsiasi diritto, che trasforma l'individuo in uomo generico, spoglio di ogni significato e privo dell'espressione e dell'azione.

description: We discuss the propagation of bosons (scalars, gauge fields and gravitons) at high energy in the context of the spectral action. Using heat kernel techniques, we find that in the high-momentum limit the quadratic part of the action does not contain positive powers of the derivatives. We interpret this as the fact that the two point Green functions vanish for nearby points, where the proximity scale is given by the inverse of the cutoff.

Known distribution: Northeast Pacific Ocean: Oregon (Karling, 1986).
Material: Observations on five live animals. Three whole mounts (BBM MI4046 – MI4048). 18S rRNA (G e n B a n k a c c e s s i o n # M F 3 2 1 7 4 9), 2 8S r R N A (GenBank accession # MF321759).
Remarks: Animals are 0.7– 1 mm long and appear plumper and more Proxenetes- shaped than described by Karling (1986) (Fig. 4B). Internal organization typical for species of Ceratopera with paired lenticular eyes, rostral rhabdite tracks, a pharynx located mid-body, paired testes situated behind the pharynx, paired ovaries and vitellaria. Two large ovate seminal vesicles are connected to the rounded copulatory bulb.
The stylet is 97–106 μ m long (x = 100 μ m, n = 3; non-axial: 52–57 μ m) and resembles the stylet of C. pilifera as described by Karling (1986). It consists of a curved stylet proper, measuring 74–80 μ m (x = 76 μ m, n = 3), with a 23- to 26- μ m-long (x = 24 μ m, n = 3) proximal base, and a curved, funnel-shaped, 46- to 47- μ m-long (x = 46 μ m, n = 3) accessory mantle piece (Fig. 4F). These measurements correspond to the ones from the Oregonian specimens. The hair-like eponymous protrusion of the accessory mantle piece could not be observed in our specimens. However, a thickened part of the convex edge of the mantle piece (arrow in Fig. 4F) corresponds to this structure. Moreover, the needle-like structure on the accessory piece in figure 67 in Karling (1986) could easily be interpreted as a thickened edge rather than a hair-like protrusion.
The funnel-shaped and distally curled bursal appendage measures 78–88 μ m (x = 82 μ m; n = 3) and is typical for species of Ceratopera sensu Den Hartog. Distally it splits into two 29- to 32- μ m-long tubes (x = 31 μ m; n = 3).
Based on the strong resemblance of the stylet and bursal appendage with those of C. pilifera, we attribute our specimens to this species.

description: We study a microscopic model of a thermocouple device with two connected correlated quantum wires driven by a constant electric field. In such isolated system we follow the time-- and position--dependence of the entropy density using the concept of the reduced density matrix. At weak driving, the initial changes of the entropy at the junctions can be described by the linear Peltier response. At longer times the quasiequilibrium situation is reached with well defined local temperatures which increase due to an overall Joule heating. On the other hand, strong electric field induces nontrivial nonlinear thermoelectric response, e.g. the Bloch oscillations of the energy current. Moreover, we show for the doped Mott insulators that strong driving can reverse the Peltier effect.

description: We compute the logarithmic correction to black hole entropy about exponentially suppressed saddle points of the Quantum Entropy Function corresponding to Z(N) orbifolds of the near horizon geometry of the extremal black hole under study. By carefully accounting for zero mode contributions we show that the logarithmic contributions for quarter--BPS black holes in N=4 supergravity and one--eighth BPS black holes in N=8 supergravity perfectly match with the prediction from the microstate counting. We also find that the logarithmic contribution for half--BPS black holes in N = 2 supergravity depends non-trivially on the Z(N) orbifold. Our analysis draws heavily on the results we had previously obtained for heat kernel coefficients on Z(N) orbifolds of spheres and hyperboloids in arXiv:1311.6286 and we also propose a generalization of the Plancherel formula to Z(N) orbifolds of hyperboloids to an expression involving the Harish-Chandra character of SL(2,R), a result which is of possible mathematical interest.

The data were obtained with the EUDET telescope Aconite at DESY and are compared to parametrisations as used in the Geant4 software package. We find good agreement between data and simulation in the scattering distribution width but large deviations in the shape of the distribution. In order to achieve a better description of the shape, a new scattering model based on a Student's t distribution is developed and compared to the data.

description: Deep imaging of the Sgr A complex at 6 cm wavelength with the B and C configurations of the Karl G. Jansky VLA has revealed a new population of faint radio filaments. Like their brighter counterparts that have been observed throughout the Galactic Center on larger scales, these filaments can extend up to ~10 parsecs, and in most cases are strikingly uniform in brightness and curvature. Comparison with a survey of Paschen-alpha emission reveals that some of the filaments are emitting thermally, but most of these structures are nonthermal: local magnetic flux tubes illuminated by synchrotron emission. The new image reveals considerable filamentary substructure in previously known nonthermal filaments (NTFs). Unlike NTFs previously observed on larger scales, which tend to show a predominant orientation roughly perpendicular to the Galactic plane, the NTFs in the vicinity of the Sgr A complex are relatively randomly oriented. Two well-known radio sources to the south of Sgr A - sources E and F - consist of numerous quasi-parallel filaments that now appear to be particularly bright portions of a much larger, strongly curved, continuous, nonthermal radio structure that we refer to as the "Southern Curl". It is therefore unlikely that sources E and F are HII regions or pulsar wind nebulae. The Southern Curl has a smaller counterpart on the opposite side of the Galactic Center - the Northern Curl - that, except for its smaller scale and smaller distance from the center, is roughly point-reflection symmetric with respect to the Southern Curl. The curl features indicate that some field lines are strongly distorted, presumably by mass flows. The point symmetry about the center then suggests that the flows originate near the center and are somewhat collimated.

description: Self-aligned double patterning (SADP) has become a promising technique to push pattern resolution limit to sub-22nm technology node. Although SADP provides good overlay controllability, it encounters many challenges in physical design stages to obtain conflict-free layout decomposition. In this paper, we study the impact on placement by different standard cell layout decomposition strategies. We propose a SADP friendly standard cell configuration which provides pre-coloring results for standard cells. These configurations are brought into the placement stage to help ensure layout decomposability and save the extra effort for solving conflicts in later stages.
The Royal Court Theatre 1968-1975: Fraught and Fruitful Years

description: From the establishment of the English Stage Company at The Royal Court Theatre in 1956through to the late 1960s, the Court was widely viewed as a champion of theatricalfreedoms and progressive ideals, playing a decisive role in the abolition of censorship asexercised by the Lord Chamberlain until 1968. Narratives of the ensuing 1968-1975 periodtend to recount an era when the Court was out of step with contemporary developments intheatre and blame is frequently placed on intergenerational tensions between the Court’sestablished management and a band of emerging English male playwrights who claim tohave been unsupported by the theatre at this time.This study goes against the received scholarly grain concerning these years at theCourt, and maps an alternative reading of this narrative. This thesis provides evidence thatthe Court of the early 1970s experienced a time of significant seed-sowing, that these wereyears in which the Sloane Square institution experimented with alternative theatre andenthusiastically programmed subaltern and female playwrights, and that this was a move instepwith contemporaneous international trends in theatre. By revealing this understandingof events, the thesis contends that the artistic directorship of Oscar Lewenstein (1972-1975)was a direct reaction against an elitist culture at the Court and an institutional habitus whichwas rooted in and informed by the decline of the British Empire and a related fear of theforeign. This thesis proposes that the subsequent occlusion of this version of events is due ingreat part to the consistent and ongoing privileging of negative accounts of the period by theemerging young white English male playwrights of the era, over the more positivecommentary provided by their subaltern and female counterparts who were empoweredunder Lewenstein’s aegis.

description: We derive the generalized magneto-absorption spectra for curved graphene nanorib- bons and carbon nanotubes by using the Peierls tight-binding model. The main spectral characteristics and the optical selection rules result from the cooperative or competitive relationships between the geometric structure and a magnetic field. In curved ribbons, the dominant selection rule remains unchanged during the variation of the curvature. When the arc angle increases, the prominent peaks are split, with some even vanishing as the angle exceeds a critical value. In carbon nanotubes, the angular-momentum coupling induces extra selection rules, of which more are revealed due to the increase of either (both) of the factors: tube diameter and field strength. Particularly once the two factors exceed certain critical values, the optical spectra could reflect the quasi-Landau-level structures. The identifying features of the spec- tra provide insight into optical excitations for curved systems with either open or closed boundary condition.

description: Searching in the Internet for some object characterised by its attributes in the form of data, such as a hotel in a certain city whose price is less than something, is one of our most common activities when we access the Web. We discuss this problem in a general setting, and compute the average amount of time and the energy it takes to find an object in an infinitely large search space. We consider the use of N search agents which act concurrently. Both the case where the search agent knows which way it needs to go to find the object, and the case where the search agent is perfectly ignorant and may even head away from the object being sought. We show that under mild conditions regarding the randomness of the search and the use of a time-out, the search agent will always find the object despite the fact that the search space is infinite. We obtain a formula for the average search time and the average energy expended by N search agents acting concurrently and independently of each other. We see that the time-out itself can be used to minimise the search time and the amount of energy that is consumed to find an object. An approximate formula is derived for the number of search agents that can help us guarantee that an object is found in a given time, and we discuss how the competition between search agents and other agents that try to hide the data object, can be used by opposing parties to guarantee their own success.

Publisher: name: University of Lincoln

Subjects: W160 - Fine art conservation

description: This thesis contributes towards the understanding of nineteenth-century decorative wall-coverings by establishing a foundational understanding of the first ten years of Lincrusta-Walton, invented in 1877 by Frederick Walton (1834 –1928), the inventor of Linoleum. As a business history, this study builds upon the very limited literary, archival andmaterial reference held by LINCRUSTA® by establishing and highlighting contemporary use. Additionally, an understanding of the foundation of the company will be established by scrutinising previously unexplored primarysources from contemporary trade literature and other published materials sourced through LINCRUSTA®, Crown Paints and other relevant archives and on-line resources. Moreover, this thesis recognises and identifies the earliest dated catalogue within the public domain and establishes the first Lincrusta-Walton designs; whilst also reconciling and illuminating previously unattributed designs by Dr Christopher Dresser and contributions made to the design catalogue by Lewis Foreman Day. Additionally, discussion of the commercial, cultural and consumer history of the company will provide rigor and a contextual rationale from which Lincrusta-Walton and its significance within the home and market setting of the 1870’s and 1880’s, can be more fully appreciated and understood.
A Complete Spectral Analysis of the Jackiw-Rebbi Model, Including its Zero Mode

description: In this paper we present a complete and exact spectral analysis of the $(1+1)$-dimensional model that Jackiw and Rebbi considered to show that the half-integral fermion numbers are possible due to the presence of an isolated self charge conjugate zero mode. The model possesses the charge and particle conjugation symmetries. These symmetries mandate the reflection symmetry of the spectrum about the line $E=0$. We obtain the bound state energies and wave functions of the fermion in this model using two different methods, analytically and exactly, for every arbitrary choice of the parameters of the kink, i.e. its value at spatial infinity ($θ_0$) and its scale of variations ($μ$). Then, we plot the bound state energies of the fermion as a function of $θ_0$. This graph enables us to consider a process of building up the kink from the trivial vacuum. We can then determine the origin and evolution of the bound state energy levels during this process. We see that the model has a dynamical mass generation process at the first quantized level and the zero-energy fermionic mode responsible for the fractional fermion number, is always present during the construction of the kink and its origin is very peculiar, indeed. We also observe that, as expected, none of the energy levels crosses each other. Moreover, we obtain analytically the continuum scattering wave functions of the fermion and then calculate the phase shifts of these wave functions. Using the information contained in the graphs of the phase shifts and the bound states, we show that our phase shifts are consistent with the weak and strong forms of the Levinson theorem. Finally, using the weak form of the Levinson theorem, we confirm that the number of the zero-energy fermionic modes is exactly one.

The Effectiveness of Compulsory Arbitration in the Settlement of Disputed Marine Insurance Claims: A Case Study of Saudi Arabia
Creators: name: Marer, Amer
Publisher: name: University of Lincoln
Year: 2023
Subjects: M200 - Law by topic

description: Arbitration has an effective role in the settlement of commercial disputes. Legal practitioners in arbitration argue that it is more efficient, faster and economical than the litigation system. It is trite that investors gravitate towards emerging economies with effective legal framework. Saudi Arabia being an important shipping hub, its dispute resolution system is of paramount importance to investors particularly in respect of settlement of disputed marine insurance claims. The legal system of Saudi Arabia is principally moulded along the lines of Sharia law. There are, however, western-styled legislations regulating specific aspects of the Saudi Arabian legal system. The dual existence of Sharia laws and legislations led to the respective creation of Sharia courts and administrative committees for the settlement of disputes. This duality creates ambiguity, tension and chaos in the legal system thereby making settlement of disputed marine insurance claims difficult and unpredictable. The author believes in the effectiveness of compulsory arbitration as an efficient tool in resolving complex commercial disputes generally and as a result of the inherent complications of the present Saudi Arabian legal framework. This thesis, therefore, examines the present legal regime for the resolution of disputed marine insurance claims in Saudi Arabia and recommends the introduction of compulsory arbitration in light of the recently enacted Saudi Arbitration Law of 2012, the Enforcement Law of 2012 and the establishment of the Saudi Centre for Commercial Arbitration. The compulsory arbitration suggested by the author is a statutory obligation to arbitrate imposed on disputing parties as opposed to a pre-dispute arbitration agreement entered into by the parties. If introduced, compulsory arbitration will create certainty in the marine insurance dispute resolution framework, which will invariably boost investors’ confidence in the Kingdom. In discussing the theme of this research, the laws governing marine insurance in Saudi Arabia, the validity of conventional forms of insurance under Sharia law and Sharia compliant forms of insurance will be considered. A comparison will also be undertaken between the old Saudi Arbitration Law of 1983 and the Arbitration Law of 2012 showing the improvement in the Saudi Arabian arbitration system and the areas where reforms are needed to ensure compatibility with international standards.

description: We give certain properties which are satisfied by the descendant set of a vertex in an infinite, primitive, distance transitive digraph of finite out-valency and provide a strong structure theory for digraphs satisfying these properties. In particular, we show that there are only countably many possibilities for the isomorphism type of such a descendant set, thereby confirming a conjecture of the first Author. As a partial converse, we show that certain related conditions on a countable digraph are sufficient for it to occur as the descendant set of a primitive, distance transitive digraph.
