description: We describe numerical methods for incorporating gas dynamics into cosmological simulations and present illustrative applications to the cold dark matter (CDM) scenario. Our evolution code, a version of TreeSPH (Hernquist \& Katz 1989) generalized to handle comoving coordinates and periodic boundary conditions, combines smoothed--particle hydrodynamics (SPH) with the hierarchical tree method for computing gravitational forces. The Lagrangian hydrodynamics approach and individual time steps for gas particles give the algorithm a large dynamic range, which is essential for studies of galaxy formation in a cosmological context. The code incorporates radiative cooling for an optically thin, primordial composition gas in ionization equilibrium with a user-specified ultraviolet background. We adopt a phenomenological prescription for star formation that gradually turns cold, dense, Jeans-unstable gas into collisionless stars, returning supernova feedback energy to the surrounding medium. In CDM simulations, some of the baryons that fall into dark matter potential wells dissipate their acquired thermal energy and condense into clumps with roughly galactic masses. The resulting galaxy population is insensitive to assumptions about star formation; we obtain similar baryonic mass functions and galaxy correlation functions from simulations with star formation and from simulations without star formation in which we identify galaxies directly from the cold, dense gas.

Structural and functional studies on Photosystem II from thermosynechococcus elongatus
Creators: name: Douglass, Jeffrey
Publisher: name: Imperial College London
Year: 2015

description: Photosystem II is a membrane-bound complex found in plants, eukaryotic algae and cyanobacteria which converts photo-excitation energy into chemical energy in the form of both oxidising and reducing power, catalysing the oxidation of water and reduction of quinone. The structure of this enzyme is tuned to balancing thermodynamic and quantum efficiency while minimising photodamage. This thesis tests a number of hypotheses regarding structural and functional aspects of this enzyme, addressing (1) the importance of structural differences between normal- and high-light-induced protein isoforms, (2) the binding mode of the inhibitor DCMU, (3) electron transfer from the primary quinone acceptor QA to the terminal quinone acceptor QB and (4) the structural origins of functional differences between redox-active tyrosines YZ and YD, using the thermophilic cyanobacterium Thermosynechococcus elongatus as a model organism. A crystal structure of PSII containing the PsbA3, the high-light isoform of the D1 protein which binds cofactors involved in the active electron transfer chain, is presented, demonstrating structural similarities with PsbA1. Crystallographic evidence is also presented which supports the binding of DCMU to D2-Ser264 and D2-Phe265 in this isoform, similar to predictions from PsbA1. Kinetic studies show that the half-times of electron transfer from QA- to QB and QA- to QB- are around 400 μs and 1 ms respectively, and the implications of these rates for structural studies are discussed. Finally, electron paramagnetic resonance experiments provide evidence that a hydrogen-bonding network linking YD and CP47-Glu364 is not a major determinant of functional differences between YZ and YD.

Numerical modelling of polydispersed flows using an adaptive-mesh finite element method with application to froth flotation
Creators: name: Bhutani, Gaurav
Publisher: name: Imperial College London
Year: 2016

description: An efficient numerical framework for the macroscale simulation of three-phase polydispersed flows is presented in this thesis. The primary focus of this research is on modelling the polydispersity in multiphase flows ensuring the tractability of the solution framework. Fluidity, an open-source adaptive-mesh finite element code, has been used for solving the coupled equations efficiently. Froth flotation is one of the most widely used mineral processing operations. The multiphase, turbulent and polydispersed nature of flow in the pulp phase in froth flotation makes it all the more challenging to model this process. Considering that two of the three phases in froth flotation are polydispersed, modelling this polydispersity is particularly important for an accurate prediction of the overall process. The direct quadrature method of moments (DQMOM) is implemented in the Fluidity code to solve the population balance equation (PBE) for modelling the polydispersity of the gas bubbles. The PBE is coupled to the Eulerian--Eulerian flow equations for the liquid and gas phases. Polydispersed solids are modelled using separate transport equations for the free and attached mineral particles for each size class. The PBE has been solved using DQMOM in a finite element framework for the first time in this work. The behaviour of various finite element and control volume discretisation schemes in the solution of the PBE is analysed. Rigorous verification and benchmarking is presented along with model validation on turbulent gravity-driven flow in a bubble column. This research also establishes the importance of modelling the polydispersity of solids in flotation columns, which is undertaken for the first time, for an accurate prediction of the flotation rate. The application of fully-unstructured anisotropic mesh adaptivity to the polydispersed framework is also analysed for the first time. Significant improvement in the solution efficiency is reported through its use.

description: Out-of-time-ordered correlators (OTOCs) have received considerable recent attention as qualitative witnesses of information scrambling in many-body quantum systems. Theoretical discussions of OTOCs typically focus on closed systems, raising the question of their suitability as scrambling witnesses in realistic open systems. We demonstrate empirically that the nonclassical negativity of the quasiprobability distribution (QPD) behind the OTOC is a more sensitive witness for scrambling than the OTOC itself. Nonclassical features of the QPD evolve with timescales that are robust with respect to decoherence and are immune to false positives caused by decoherence. To reach this conclusion, we numerically simulate spin-chain dynamics and three measurement protocols (the interferometric, quantum-clock, and weak-measurement schemes) for measuring OTOCs. We target experiments based on quantum-computing hardware such as superconducting qubits and trapped ions.

description: Cardosin A is an aspartic protease present in large amount in the pistils of cardoon flowers. This
protease is known to contain an -Arg-Gly-Asp- (RGD) motif located on the molecular surface. In
this study, we found that isolated recombinant cardosin A attached to human epithelial cells
A549, mediated by the binding of its RGD motif to cell surface integrins. The cell bound cardosin
A was internalized to endosomes and lysosomes and triggered the permeability of lysosomal
membrane leading to apoptosis of the epithelial cells. These events are identical to those
observed for three RGD-containing aspartic proteases, Saps 4-6, secreted by Candida albicans.
Such a process, which has been called the Trojan Horse mechanism, is believed to benefit the
invasion of C. albican into the epithelium of the host. The location of the RGD motifs of cardosin
A and Saps 4-6 are on the opposite ends of the homologous three-dimensional structures,
suggesting that the Trojan Horse mechanism is insensitive to the RGD position. Current finding
also suggests that cardosin A may have a defensive function against the ingestion of cardoon
flowers by human, insects, and other herbivores.

Dust in High Redshift Radio Galaxies and the Early Evolution of Spheroidal Galaxies

Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)

description: Several lines of evidence suggest that early-type galaxies might have been very dusty during their initial evolutionary stages, characterized by intense star formation activity. The radio selection has provided, by far, the richest samples of high-$z$ galaxies, most likely of early type, which may therefore yield crucial direct information on the period when the bulk of stars were born. In order to investigate the role of dust in these phases, we have analyzed recent observations of a number of high-$z$ radio galaxies in the framework of a self-consistent scenario for the evolution of early type galaxies. The available data can be fully accounted for by ``opaque'' models similar to that already used by Mazzei and De Zotti (1994a) to fit the spectrum of the hyperluminous galaxy IRAS~F$10214+4724$. However, there is still considerable latitude for models. Good fits can be obtained with galactic ages ranging from 0.05 to 2 Gyr. Crucial constraints may be provided by ground-based sub-mm measurements and by observations with the forthcoming Infrared Space Observatory (ISO).

A UV assisted methodology for functional oxide film formation from small molecules
Creators: name: Bhamrah Harley, Jasvir Kaur
Publisher: name: Imperial College London
Year: 2016

description: The development of organic electronics has progressed rapidly due to the demand for lower cost, large scale fabrication of devices using inexpensive materials with flexible substrates. The field has seen the discovery of many suitable organic substitutes for traditional electronic component materials, in particular, by polymers and small molecules. One class of materials, metal oxides, have yet to find organic alternatives capable of performing to standards required. In this thesis, a non-toxic, room temperature method for functional oxide film formation from small molecules frequently employed as active layers in devices is explored to fully determine the mechanism by which the metal oxide is formed. Comparison of precursors, ZnPc (zinc phthalocyanine) and ZnTPP (zinc tetraphenylporphyrin), with contrasting morphology when deposited as thin films demonstrates the importance of the oxygen-assisted mechanism and its relation to grain boundaries. It is demonstrated that efficiency of oxide formation may be improved by choice of a crystalline precursor. Heterostructures of ZnPc and PTCDA (3,4,9,10-perylenetetracarboxylic dianhydride), an archetypal organic semiconductor, are used as a model to determine the effect of the UV process for oxide production on underlying organic layers. We show that approximately half the precursor film reacts before the underlying layer is affected. The structures also reveal no effect of molecular orientation on the rate of oxide formation and templated films of ZnPc on PTCDA are correctly indexed for the first time. The use of PTCDA also confirms that inclusion of an oxygen-containing molecule can be employed as a method to increase the rate of film degradation. Finally, nanosphere lithography of ZnPc films is combined with the UV assisted process to form regular arrays of hollow triangular nanostructures or pillars with the aim of creating structures suitable for photonic use.

description: When multilingual communication through a speech-to-speech translation system is supported by multimodal features, e.g. pen-based gestures, the following issues arise concerning the nature of the supported communication: a) to what extend does multilingual communication differ from ‘ordinary’ monolingual communication with respect to the dialogue structure and the communicative strategies used by participants; b) the patterns of integration between speech and gestures. Building on the outcomes of a previous work, we present results from a study aimed at addressing those issues. The initial findings confirm that multilingual communication, and the way in which it is realized by actual systems (e.g., with or without the push-to-talk mode) affects the form and structure of the conversation.

description: Determining the internal kinematics of a galaxy from planetary nebulae (PN) is usually a two step process in which the candidate PN are first identified in a target galaxy and then, in a follow up run, spectra are obtained. We have implemented a new technique in which two dispersed images at the wavelength of the [OIII] emission line at 5007A are combined to yield positions, magnitudes and velocities of the PN population in a single step. A reduction in observing time of about a factor 2 is attainable. We present here the proof-of-principle results.

Field Stars and Clusters of the Galactic Bulge: Implications for Galaxy Formation
Creators: name: Minniti, Dante
Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The results of a kinematic study of the Galactic bulge based on spectra of red giants in fields at projected distances of 1.4-1.8 kpc from the Galactic center are presented. There is a marked trend of kinematics with metallicity, in the sense that the more metal-poor population has higher velocity dispersion and lower rotation velocity than the metal-rich population. The K giants more metal--poor than [Fe/H] = -1 have halo-like kinematics, with no significant rotation and sigma = 120 km/s independent of Galactocentric distance. The velocity dispersion of the giants with [Fe/H] > -1 decreases with increasing Galactocentric distance, and this population is rotating with V = 0.9 km/s/degree. The present observations, together with the observed metallicity gradient imply bulge formation through dissipational collapse. In such a picture, low angular momentum gas lost from the formation of the halo was deposited in the bulge. The bulge would then be younger than the halo. Observations of the Galactic globular cluster system are consistent with this picture, if we associate the metal-rich globular clusters within 3 kpc of the Galactic center with the bulge rather than with the thick disk or halo. Data on the RR Lyr in Baade's window are also consistent with this picture if these stars are considered part of the inner halo rather than the bulge.

Regulation of calcium handling proteins by microRNA-1 in heart failure
Creators: name: Mills, Adam
Publisher: name: Imperial College London
Year: 2015

description: Heart failure has a complex pathophysiology, a diverse aetiology, an increasing prevalence and only palliative treatment is currently available. The underlying molecular cause of cardiomyocyte malfunction is not fully understood. MicroRNA-1 is a post transcriptional genetic regulator that is highly expression expressed in the myocardium and has been found to influence cardiomyocyte proteins that are key for maintaining calcium homeostasis and contractility; the sarcoplasmic reticulum calcium transport ATPase (SERCA2a) and the sodium calcium exchanger (NCX). MicroRNA-1 expression is disrupted in both in vivo models and heart failure patients; this makes the impact of altered microRNA-1 expression on the development of heart failure pathophysiology an interesting target for investigation. Using in vitro and in vivo models of heart failure, experiments were conducted to increase microRNA-1 expression by viral or non-viral transfection techniques. This produced a number of interesting results relating to cardiomyocyte function; impaired Beta-adrenoceptor mediated contractility, a hallmark of the heart failure phenotype, was reversed and can most likely be attributed to an increase in cyclic adenosine monophosphate (cAMP) production. SERCA2a driven sarcoplasmic reticulum (SR) calcium loading was improved and a greater release of calcium from the SR was recorded. Questions remain around the mechanism connecting microRNA-1 to these targets, particularly as gene expression was unaffected by increased microRNA-1. Future experiments would focus on bridging this understanding to expand upon these results. The prognostic potential of circulating microRNAs in serum samples taken from a well characterised population of heart failure patients was also investigated. Two separate microarray platforms were conducted and the expression of a shortlist of 15 microRNAs validated further. Unfortunately no microRNA could be identified that could consistently distinguish between good and poor prognosis heart failure patients. This does not discount circulating microRNAs as possible prognostic biomarkers of heart failure, but a different approach would be required for future experiments.

description: The electromagnetic Casimir effect manifests as the interaction between uncharged conducting objects that are placed in a vacuum. More generally, the Casimir-like effect denotes an induced interaction between external bodies in a fluctuating medium. We study the Casimir-like interaction between two impurities embedded in a weakly interacting one-dimensional Bose gas. We develop a theory based on the Gross-Pitaevskii equation that accounts for the effect of quantum fluctuations. At small separations, the induced interaction between the impurities decays exponentially with the distance. This is a classical result that can be understood using the mean-field Gross-Pitaevskii equation. We find that at larger distances, the induced interaction crosses over into a power law dependence due to the quantum fluctuations. We obtain an analytic expression for the interaction that interpolates between the two limiting behaviors. The obtained result does not require any regularization.

Minimal Hypersurfaces in nearly $\mathrm{G}_2$ Manifolds

description: We study hypersurfaces in a nearly $\mathrm{G}_2$ manifold. We define various quantities associated to such a hypersurface using the $\mathrm{G}_2$ structure of the ambient manifold and prove several relationships between them. In particular, we give a necessary and sufficient condition for a hypersurface with an almost complex structure induced from the $\mathrm{G}_2$ structure of the ambient manifold, to be nearly K$\ddot{\text{a}}$hler. Then using the nearly $\mathrm{G}_2$ structure on the round sphere $S^7$, we prove that for a compact minimal hypersurface $M^6$ of constant scalar curvature in $S^7$ with the shape operator $A$ satisfying $|A|^2>6$, there exists an eigenvalue $λ>12$ of the Laplace operator on $M$ such that $|A|^2=λ- 6$, thus giving the next discrete value of $|A|^2$ greater than $0$ and $6$, thus generalizing an earlier result about nearly K$\ddot{\text{a}}$hler $S^6$.

Maximum variations in UBVRI: 5.12, 5.31, 4.73, 2.59, and 2.54 and color indices of U-B = -0.11 +/- 0.20, B-V= 1.0 +/- 0.11, V-R= 0.73 +/- 0.19, V-I= 1.42 +/- 0.25, R-I= 0.82 +/- 0.11, and B-I= 2.44 +/- 0.29 have been obtained from the literature; The Jurkevich method is used to investigate the existence of periods in the B band light curve, and a long-term period of 14 years is found. The 0.6 and 0.88 year periods reported by Webb et al.(1988) are confirmed. In addition, a close relation between B-I and B is found, suggesting that the spectra flattens when the source brightens.

description: We consider the constraints on the physical parameters of a homogeneous SSC model that can be derived from the spectral shape and variability of TeV blazars. Assuming that the relativistic electron spectrum is a broken power law, where the break energy $γ_b$ is a free parameter, we write the analytical formulae that allow to connect the physical parameters of the model to observable quantities. The constraints can be summarized in a plane where the coordinates are the Doppler factor and the magnetic field. The consistency between the break energy and the balance between cooling and escape and the interpretation of the soft photon lags measured in some sources as radiative cooling times are treated as additional independent constraints. We apply themethod to the case of three well known blazars, PKS 2155-304, Mrk 421 and Mrk 501.

Doing good while making profit: perspectives on reconciling multiple objectives in social enterprises
Creators: name: De Cuyper, Lien
Publisher: name: Imperial College London
Year: 2017

description: This dissertation looks at social ventures that create social impact whilst being self-sustainable. By adopting three different theoretical perspectives, various aspects of organizations with multiple social and economic objectives are highlighted. Study 1 examines the hybrid nature of social ventures. It examines the conditions under which social ventures develop hybrid value creating activities to deal with their economic and social goals. Based on data from 11 social ventures, the findings are based on a combination of an inductive analysis and fsQCA analysis. The focal point of the study is how the interplay of the exclusiveness of the beneficiary target group, the overlap between customers and beneficiaries, and the visibility of the social mission in the value offering, influences the extent to which social ventures hybridize their means. The study contributes to the literature on social ventures specifically, and hybrid ventures more generally. Study 2 is based on a qualitative and inductive ethnographic study of a social venture. It sheds light on how organizational members have an imprinting effect on a venture beyond the founding phase. The model proposed in this study illuminates how the imprinting process is an ongoing, two-way interaction between the individual and the organizational level. The analysis shows how the initial imprint of the venture attracts people with specific social identities, and how bottom-up involvement of organizational members impacts on the imprint through three processes: projecting, sharing and contextualizing. This study adds to the literature on imprinting on one hand, and to literature on social ventures on the other hand. Study 3 is a comparative study of two social ventures bringing electrification to rural communities in a bottom-of-the-pyramid market. The study unpacks how these ventures design governance models to align the heterogeneous interests of their stakeholders - including customers, employees and local communities – with their own organizational social and economic objectives. On one hand, the results of the analysis show how the two ventures differ in terms of a customer versus community focus in their governance approach. On the other hand, the analysis shows how this divergent take on governance is driven by a different perception of stakeholder categories, a dissimilar conceptualization of beneficiaries of the social mission, and a different extent of adopting relational versus transactional approaches towards the stakeholders. The study is a response to calls for research on governance in the context of organizations with multiple social and economic objectives.

description: In this thesis, we develop a perturbative approximation for the solution of Lindblad master equations with time-dependent generators that satisfies the fundamental property of complete positivity, as essential for quantum simulations and optimal control of open quantum systems. By probing our method to several explicit examples we show that ensuring this property not only improves the accuracy of the perturbative approximation substantially, but also it permits to read off the effective dissipative processes . Subsequently, we design optimal entangling quantum gates for trapped ions mediated by a bus mode which is subject to decoherence. We show that suitably designed polychromatic control pulses, help to suppress the qubit-phonon entanglement substantially while maintaining the mediated interaction. This leads to a considerable reduction in the gate infidelity, in particular, for multi-qubit gates this yields a significant improvement in the gate performance.

description: We calculate the damping of quadrupole f and low order g modes (primary modes) by nonlinear coupling to other modes of the star. This damping is orders of magnitude more rapid than direct radiative damping when the primary amplitude is large, as in tidal capture. Primary modes destabilize high degree g-modes of half their frequency (daughter modes) by 3-mode coupling in radiative zones. In sunlike stars, the growth time $\equivη^{-1}\approx 4 E_{0,42}^{-1/2}$ days, where $E_{0,42}$ is the initial energy of the primary mode in units of $10^{42}~$erg, and of order $10^{10}E_{0,42}^{5/4}$ daughters are unstable. The growth rate is approximately equal to the angular frequency of the primary mode times its dimensionless radial amplitude, $δR/R_*\approx 0.002E_{0,42}^{1/2}$. Although the daughter modes are limited by their own nonlinearities, collectively they absorb most of the primary mode's energy after a time $\sim 10η^{-1}$ provided $E_{0}> 10^{40}~\mbox{erg}$. In fact nonlinear mode interaction may be the dominant damping process if $E_0\gtrsim 10^{37}~\mbox{erg}$. Our results have application to tidally captured main sequence globular cluster stars of mass $\ge 0.5 M_{\sun}$; the tidal energy is dissipated in the radiative core of the star in about a month, which is less than the initial orbital period.

description: The demand of Rare Earth Elements (REEs) has increased for the development of clean and green technologies. Conventional geological sources of REE are insufficient to overcome the high demand of REE; hence, the secondary resources are being actively explored. Coal ashes (CAs), a potentially hazardous material, is one of the best secondary sources containing high concentration of REE. The present study aims to explore the abundance of REE in coal and coal ash from different Thermal Power Stations (TPS). The mineralogy and surface morphology of all samples have been determined. The coals mostly consist of quartz and kaolinite, whereas CAs predominantly contain quartz and mullite. Both coal and CAs are dominated by LREE elements, followed by MREE and HREE. The outlook coefficient (Cout) is close to “1” and the critical percentage (Cp) is more than 30%. Coal ash from some of the TPS is identified as secondary source for REE. Fractionation study of REE from coal to CA is carried out to understand the feasibility of CA. A Pearson correlation has been plotted for individual REE elements with other parameters to understand the affinity of REE to different phases of CA.

description: In recent papers, a few physicists studying Black Hole perturbation theory in General Relativity have tried to construct the initial part of a differential sequence based on the Kerr metric, using methods similar to the ones they already used for studying the Schwarzschild geometry. Of course, such a differential sequence is well known for the Minkowski metric and successively contains the Killing (order 1), the Riemann (order 2) and the Bianchi (order 1 again) operators in the linearized framework, as a particular case of the {\it Vessiot structure equations}. In all these cases, they discovered that the {\it compatibility conditions} (CC) for the corresponding Killing operator were involving {\it a mixture of both second order and third order CC} and their idea has been to exhibit only a {\it minimal number of generating ones}. However, even if they exhibited a link between these differential sequences and the number of parameters of the Lie group preserving the background metric, they have been unable to provide an intrinsic explanation of this fact, being limited by the technical use of Weyl spinors, complex Teukolsky scalars or Killing-Yano tensors. Using the formal theory of systems of partial differential equations and Lie pseudogroups, the purpose of this difficult computational paper is to provide new intrinsic differential and homological methods involving the Spencer operator in order to revisit and solve these questions, not only in the previous cases but also in the specific case of any Lie group or Lie pseudogroup of transformations. These new tools are now available as computer algebra packages.
description: In this v2 we improve the search of generating compatibility conditions for the Killing operators used in general relativity and the corresponding differential sequences, by means of new differential homological methods. The existence of a partition 10=4+4+2 of the Ricci tensor questions the mathematical coherence of Einstein equations with group theory and formal integrability
Electronic social capital for self-organising multi-agent systems
Creators: name: Petruzzi, Patricio
Publisher: name: Imperial College London

description: It is a recurring requirement in open systems, such as networks, distributed systems and socio-technical systems, that a group of agents must coordinate their behaviour for common good. In those systems – where agents are heterogeneous – unexpected behaviour can occur due to errors or malice. Agents whose practices free-ride the system can be accepted to a certain level; however, not only do they put the stability of the system at risk, but they also compromise the agents that behave according to the system’s rules. In social systems, it has been observed that social capital is an attribute of individuals that enhances their ability to solve collective action problems. Sociologists have studied collective action through human societies and observed that social capital plays an important role in maintaining communities though time as well as in simplifying the decision making in them. In this work, we explore the use of Electronic Social Capital for optimising self-organised collective action. We developed a context-independent Electronic Social Capital framework to test this hypothesis. The framework comprises a set of handlers that capture events from the system and update three different forms of social capital: trustworthiness, networks and institutions. Later, a set of indicators are generated by the forms of social capital and used for decision-making. The framework was tested in different scenarios such as 2-player games, n-player games and public goods games. The experimental results show that social capital optimises the outcomes (in terms of long-term satisfaction and utility), reduces the complexity of decision-making and scales with the size of the population. This work proposes an alternative solution using Electronic Social Capital to represent and reason with qualitative, instead of traditional quantitative, values. This solution could be embedded into socio-technical systems to incentivise collective action without commodifying the resources or actions in the system.

description: In cosmological models where local cosmic strings are formed at the end of a period of inflation, the perturbations are seeded both by the defects and by the quantum fluctuations. In a subset of these models, for example those based on $D$-term inflation, the amplitudes are similar. Using our recent calculations of structure formation with cosmic strings, we point out that in a flat cosmology with zero cosmological constant and 5% baryonic component, strings plus inflation fits the observational data much better than each component individually. The large-angle CMB spectrum is mildly tilted, for Harrison-Zeldovich inflationary fluctuations. It then rises to a thick Doppler bump, covering $\ell=200-600$, modulated by soft secondary undulations. The standard CDM anti-biasing problem is cured, giving place to a slightly biased scenario of galaxy formation.
Towards an information formalism in group decision making systems with incomplete information
Creators: name: Kumar, Rishi Nalin
Publisher: name: Imperial College London

description: Human democratic and economic decision making systems face unprecedented challenges in terms of the scope and scale of their application. Owing to advances in information technology, the individuals within these systems also face fundamen- tal shifts in their ability to pool, process and share decision-relevant information, which are essential in enabling the system to function as a whole. While the de- cision making systems that prevail in industry and society are now thousands of years old, recent literature has provided inspiration for new systems in the form of empirical observations concerning how various non-human species have evolved to solve various group decision making problems throughout nature. One of the main challenges in adapting lessons from these observations is the lack of formal underpinnings in existing explanatory schemes that encompass the mechanisms of observation and communication that are both essential to making these systems work in practice and fundamental to defining them in theory. In this thesis, we demonstrate that by formalising information as a property of observables, in a systems framework, one can account for the origin and nature of the observable landscape, whilst maintaining consistency with existing definitions from previously established schemes. As will be demonstrated, introducing information formalism o↵ers a new means of establishing insights into how the components of the sys- tem interact to produce the observed, often desirable, substantive results. More broadly, by applying a cross-species information-based formalism consistently to the growing conspecific empirical literature, one can develop a new explanatory theory of the substantive properties of group decision making systems with in- complete information. Such a theory could be used to apply lessons from nature’s evolved systems to the human designed systems prevailing throughout industry and society.
