description: It is commonly accepted that institutions influence economic development of countries. But, can we also trace the effect of institutional endowment to specific sectors and regions of a country? There is a significant gap in knowledge and evidence of this issue in the literature. This paper examines this effect in the Indian electricity distribution sector and explores the influence of state-level institutional quality and economic factors on the performance of network utilities in India. Since the 1990s, India has adopted reform steps to improve the efficiency of its electricity sector. However, there remain performance differences among the utilities. We examine the performance of 52 electricity distribution utilities in 24 Indian states for the period from 2006-07 to 2011-12. The findings confirm that the quality of institutions and state-wide economic development affect the performance of the electricity distribution utilities in different states. Additionally, we simulate the cost savings from utilities� performance improvements linked with institutional enhancements. The results indicate the need to strengthen the institutions, for example through regulatory agencies reform to improve the performance of the sector.

description: In this work we propose the technique for phase-coded weak coherent states protocols utilizing two signal states and one decoy state which is found as linear combination of signal states (Schrödinger Cat states); the latter allows to overcome the USD attack. For instance, Schrödinger Cat states can be considered as even coherent states. Moreover we consider decoy states implementation based on squeezed vacuum states which might not disables USD completely yet produces discrimination probabilities low enough to distribute keys in channel with particular losses. Thus we can detect Eve simply by monitoring the detection rate of decoy states. It should be noted that this approach can be scaled to more complex schemes.

description: Blazars are radio-loud AGNs with a diluted Ca contrast, i.e., K4000 ≤ 40 %. From data reduction pipeline, the redshifts z=0.165, 0.26 and 0.09 measured for three blazar candidates, 3EG J1800-0146, 3EG J1709-0817 and 3EG J0159-3603 confirm their extragalactic nature. Their optical spectroscopic observations were obtained using Robert Stobie spectrograph (RSS) at SALT in South Africa. The spectra of 3EG J1800-0146 and 3EG J1709-0817 display spectral features of a BL Lac. The observed Ca II H & K lines at ~ 4000 Å in these spectra show a shallow depression of K4000 = 0.35 ± 0.04 and 0.24 ± 0.01, suggesting the presence of a strong non-thermal component in these sources. On the other hand, a deep depression K4000=0.54 ± 0.03 for 3EG J0159-3603 is not in accordance with what is expected for a blazar. This implies that this source is probably not a blazar.
Star Formation and Molecular Gas in Extremely Metal-poor Galaxies: Insights from the Thermal Balance in the Neutral Gas

description: The apparent lack of cold molecular gas in blue compact dwarf (BCD) galaxies is at variance with their intense star-formation episode. The CO molecule, often used a tracer of H2 through a conversion function, is selectively photodissociated in dust-poor environments and, as a result, a potentially large fraction of H2 is expected to reside in the so-called CO-dark gas, where it could be traced instead by infrared cooling lines [CI], [CII], and [OI]. Although the fraction of CO-dark gas to total molecular gas is expected to be relatively large in metal-poor galaxies, many uncertainties remain due to the difficulty in identifying the main heating mechanism associated to the cooling lines observed in such galaxies. Investigations of the Herschel Dwarf Galaxy Survey show that the heating mechanism in the neutral gas of BCDs cannot be dominated by the photoelectric effect on dust grains below some threshold metallicity, implying that other heating mechanisms need to be invoked, along with a new interpretation of the corresponding infrared line diagnostics. In the study presented here and in Lebouteiller et al. 2017, we use optical and infrared lines to constrain the physical conditions in the HII region + HI region of the BCD IZw18 (18Mpc; 2% solar metallicity) within a consistent photoionization and photodissociation model. We show that the HI region is entirely heated by a single ultraluminous X-ray source with important consequences on the applicability of [CII] to trace the star-formation rate and to trace the CO-dark gas. We derive stringent upper limits on the size of H2 clumps that may be detected in the future with JWST and IRAM/NOEMA. We also show that the nature of the X-ray source can be inferred from the corresponding signatures in the ISM. Finally we speculate that star formation may be quenched in extremely metal-poor dwarf galaxies due to X-ray photoionization.

description: It is shown that the fine structure splittings of the $2 ^3P_J$ and $3 ^3P_J$ excited states in charmonium are as large as those of the $1^3P_J$ state if the same $α_s(μ)\approx 0.36$ is used. The predicted mass $M(2 ^3P_0)=3.84$ GeV appears to be 120 MeV lower that the center of gravity of the $2 ^3P_J$ multiplet and lies below the $D\bar D^*$ threshold. Our value of $M(2 ^3P_0)$ is approximately 80 MeV lower than that from the paper by Godfrey and Isgur while the differences in the other masses are $\la 20$ MeV. Relativistic kinematics plays an important role in our analysis.

description: The existence of a nuclear electric octupole moment (EOM) requires both parity and time invariance violation. The EOMs of odd $Z$ nuclei that are induced by a particular T- and P-odd interaction are calculated. We compare such octupole moments with the collective EOMs that can occur in nuclei having a static octupole deformation. A nuclear EOM can induce a parity and time invariance violating atomic electric dipole moment, and the magnitude of this effect is calculated. The contribution of a nuclear EOM to such a dipole moment is found, in most cases, to be smaller than that of other mechanisms of atomic electric dipole moment production.

Since this calculation does not assume ordering of the transverse momenta, it includes important logarithmic contributions that are beyond those summed by the DGLAP evolution. These contributions lead to a power-like behavior for the forward DVCS amplitude.

description: Control and transport of nanoscale objects in fluids is challenging because of the unfavorable scaling of most interaction mechanisms to small length scales. We design energy landscapes for nanoparticles by accurately shaping the geometry of a nanofluidic slit and exploiting the electrostatic interaction between like charged particles and walls. Directed transport is performed by combining asymmetric potentials with an oscillating electric field to achieve a rocking Brownian motor. Using 60\,nm diameter gold spheres, we investigate the physics of the motors with high spatio-temporal resolution, enabling a parameter-free comparison with theory. We fabricated a sorting device that separates 60- and 100-nanometer particles in opposing directions within seconds. Modeling suggests that the device separates particles with a radial difference of 1 nanometer.

Bargaining with renegotiation in models with on-the-job search

Year: 2017
Subjects: On-the-job search
Bargaining
Renegotiation
Wage contracts

description: This paper studies renegotiation in models with on-the-job search, with an application to minimum wages. My formulation nests earlier models in the literature as limit cases when the frequency of renegotiation goes to zero or infinity. The equilibrium wage distribution and the bargaining outcomes are unique. When there is a strong response of turnover to a wage increase, firms accept higher wages, which increases the share of the surplus captured by the worker. Turnover responds more to wages when marginally better job offers arrive more frequently, and when renegotiation occurs less frequently. A minimum wage increase leads to a higher density of jobs at the minimum wage. This can spread up the wage distribution, as the increased density provides a motive for firms to accept higher wages in order to reduce turnover. However, this effect depends crucially on the frequency of renegotiation being low.

Implications of High-Frequency Trading for Security Markets
Creators: name: Linton, O.
name: Mahmoodzadeh, S.
Publisher: name: Apollo - University of Cambridge Repository
Year: 2018

description: High frequency trading (HFT) has grown substantially in recent years, due to fast-paced technological developments and their rapid uptake, particularly in equity markets. This paper investigates how HFT could evolve and, by developing a robust understanding of its effects, to identify potential risks and opportunities that it could present in terms of financial stability and other market outcomes such as volatility, liquidity, price efficiency and price discovery. Despite commonly held negative perceptions, the available evidence indicates that HFT and algorithmic trading (AT) may have several beneficial effects on markets. However, they may cause instabilities in financial markets in specific circumstances. Carefully chosen regulatory measures are needed to address concerns in the shorter term. However, further work is needed to inform policies in the longer term, particularly in view of likely uncertainties and lack of data. This will be vital to support evidence-based regulation in this controversial and rapidly evolving field.
Searches for new physics with tau leptons at the CMS experiment
Creators: name: Uttley, George
Publisher: name: Imperial College London
Year: 2023

description: The Standard Model (SM) of particle physics is currently the best model of the fundamental particles and their interactions. However, there are significant theoretical issues and experimental tensions with the model. The theoretical issues include the hierarchy problem which forecasts the breakdown of the SM when looking at the size of corrections needed to calculate the mass of the newest found member of the theory, the Higgs boson particle. The current experimental tensions include the B anomalies and the measurement of the muon anomalous magnetic moment. Looking for signatures of theoretical explanations to these issues offers excellent search options for new fundamental particles. This thesis describes searches for new physics that can explain both the theoretical problems and experimental tensions. This is done using tau leptons seen during Run 2 of the Large Hadron Collider at the Compact Muon Solenoid (CMS) experiment. The beyond SM theories searched for range from the Minimal Supersymmetric SM (MSSM), leptoquarks, and the type X two Higgs doublet models (2HDM). Two local excesses are observed with statistical significances of approximately 3 sigma for a resonance produced via gluon fusion in the di-tau final states, at masses of 100 GeV and 1.2 TeV. Otherwise, good agreement is observed between the SM background prediction and data. Leading constraints are placed on scenarios of the MSSM phase space and limits that shrink the allowed explanation to the B anomalies are set. The type X 2HDM, as an explanation for the muon anomalous magnetic moment measurement, is fully ruled out and many mass hypotheses in the type X 2HDM are completely excluded by this thesis.

Sub-Saharan Africa

description: In order to reduce the influence of corruption on electricity sector performance, most Sub-Saharan African countries have implemented sector reforms. However, after nearly two and half decades of reforms, there is no evidence whether these reforms have mitigated or exacerbated corruption. Neither is there evidence of performance improvements of reforms in terms of technical, economic or welfare impact. This paper aims to fill this gap. We use a dynamic panel estimator with a novel panel data set of 47 Sub-Saharan African countries from 2002 to 2013. We analyse the impact of corruption and two key aspects of electricity reform model - creations of independent regulatory agencies and private sector participation - on three performance indicators: technical efficiency, access to electricity and income. We find that corruption can significantly reduce technical efficiency of the sector and constrain the efforts to increase access to electricity and national income. However, these adverse effects are reduced where independent regulatory agencies are established and privatisation is implemented. Our results suggest that well-designed reforms not only boost economic performance of the sector directly, but also indirectly reduce the negative effects of macro level institutional deficiencies such as corruption on micro and macro indicators of performance.

Phenotypic screening reveals microbial effects on C. elegans behaviour
Creators: name: Moore, Saul
Publisher: name: Imperial College London
Year: 2022

description: Microbiota present a promising and underexploited source of novel neuroactive compounds for the treatment of neurological and psychiatric diseases in humans. However, due to the diverse and complex interactions that they have with each other and the host nervous system, identifying causal microbes and the molecules they produce remains a difficult challenge. Here, I address this challenge in the nematode worm, Caenorhabditis elegans, as it is a small bacterivore with a simple nervous system, yet it displays a variety of behavioural responses to bacteria that are observable in the laboratory and governed by conserved neural signalling pathways. I perform phenotypic screening and use custom animal tracking software to investigate worm behaviour in response to a library of Escherichia coli single- gene deletion mutants. I find that bacterial strains with disrupted iron import or respiratory chain function elicit an acute arousal behaviour in C. elegans. Subsequent experiments reveal a novel neural sensorimotor mechanism for arousal in C. elegans that is modulated by oxidative stress from its bacterial diet. Oxidative stress damage is known to contribute to the development of neurodegenerative diseases in humans, and the principal metabolic machinery and oxidative stress mechanisms involved are highly conserved in lower eukaryotes such as C. elegans. Further research using C. elegans as a model to understand how microbiota affect host oxidative stress mechanisms and alter host behaviour could lead to important therapeutic discoveries for the treatment of these diseases.

carbon pricing

description: Globally coordinated climate action has resulted in sub-optimal emissions reductions and unilateral (second-best) climate policies have so far provided the bulk of emissions reductions. This paper argues that the development of new unilateral carbon pricing policies was fostered by international signalling and technological spillover effects. The strength of both effects hinges, for each jurisdiction, on trade relations with other CO2-abating jurisdictions. We provide a stylised theoretical discussion in support of our proposition and investigate it using data on a panel of 121national jurisdictions over the period 1990-2014. Results show a strong positive association between import-weighted exposure to CO2-pricing partners and domestic environmental policy. The analysis also supports the technological spillover channel: trade-weighted installed capacity of wind and solar energy seems to prompt implementation of and more stringent carbon pricing policies.

description: Located along the Ring of Fire in the Asia Pacific, both Indonesia and the Philippines have tremendous natural resource endowments in geothermal energy. Yet, the two countries have dramatic differences in the share of installed capacity they have developed with international development assistance for geothermal development over the last decades. This paper investigates the major interests, institutions and barriers to geothermal development in Indonesia and the Philippines and then examines how closely clean energy development finance has addressed these barriers. Using qualitative analysis and data from field research in both countries, this paper investigates the effectiveness of the clean energy development finance for renewable energy development. The main findings of this research show that clean energy development finance targeted major barriers to geothermal energy development, but the finance was limited in its impacts on removing the barriers or addressing major domestic political interests, particularly in the case of Indonesia. This research also illuminated limitations of the project-based development approach to solving macro-level problems in clean energy development.

description: We employ new field-theoretical tools to study photons and jets in a non-equilibrium quark-gluon plasma. Jet broadening and photon emission takes place through radiation which is suppressed by repeated and coherent interaction with the medium. We analyze this physics in an anisotropic plasma such as is created in the early stages of heavy-ion collisions. The anisotropy introduces an angular dependence in radiation and reduces its overall rate. This can affect phenomenological predictions of the rapidity dependence and angular flow of jets and photons.

Pressure Dependence of Born Effective Charges, Dielectric Constant and Lattice Dynamics in SiC

description: The pressure dependence of the Born effective charge, dielectric constant and zone-center LO and TO phonons have been determined for $3C$-SiC by a linear response method based on the linearized augmented plane wave calculations within the local density approximation. The Born effective charges are found to increase nearly linearly with decreasing volume down to the smallest volume studied, $V/V_0=0.78$, corresponding to a pressure of about 0.8 Mbar. This seems to be in contradiction with the conclusion of the turnover behavior recently reported by Liu and Vohra [Phys.\ Rev.\ Lett.\ {\bf 72}, 4105 (1994)] for $6H$-SiC. Reanalyzing their procedure to extract the pressure dependence of the Born effective charges, we suggest that the turnover behavior they obtained is due to approximations in the assumed pressure dependence of the dielectric constant $\varepsilon_\infty$, the use of a singular set of experimental data for the equation of state, and the uncertainty in measured phonon frequencies, especially at high pressure.

Extreme canonical correlations and high-dimensional cointegration analysis

description: The simplest version of Johansen's (1988) trace test for cointegration is based on the squared sample canonical correlations between a random walk and its own innovations. Onatski and Wang (2017) show that the empirical distribution of such squared canonical correlations weakly converges to the Wachter distribution as the sample size and the dimensionality of the random walk go to infinity proportionally. In this paper we prove that, in addition, the extreme squared correlations almost surely converge to the upper and lower boundaries of the support of the Wachter distribution. This result yields strong laws of large numbers for the averages of functions of the squared canonical correlations that may be discontinuous or unbounded outside the support of the Wachter distribution. In particular, we establish the a.s. limit of the scaled Johansen's trace statistic, which has a logarithmic singularity at unity. We use this limit to derive a previously unknown analytic expression for the Bartlett-type correction coefficient for Johansen's test in a high-dimensional environment.
Ergodic properties of fractional-driven stochastic differential equations and their applications
Creators: name: Sieber, Julian
Publisher: name: Imperial College London
Year: 2023

description: This dissertation presents our research on the following problems in the asymptotic theory of dynamics driven by fractional noise: We derive regularity properties of the stationary density of stochastic differential equations driven by additive fractional Brownian motion. We prove a geometric rate of convergence of the law of the solution to fractional-driven stochastic differential equations to the stationary distribution. This improves previously known results which obtained algebraic and sub-exponential rates. We establish an averaging principle for slow-fast systems for which both motions are driven by fractional Brownian motions. We obtain an averaging principle for semi-linear stochastic differential equations driven by cylindrical fractional Brownian motion. We show a functional central limit theorem for non-autonomous ordinary differential equations in a random environment modeled by a fractional Ornstein-Uhlenbeck process.

description: We investigate the exclusive B -> pi e^+ e^- and B -> rho e^+ e^- decays in framework of the general two Higgs doublet model (model III), in which an extra phase angle in the charged--Higgs fermion coupling, i.e., a new source for CP violation exists. The CP violation for both decays are calculated and it is observed that the CP violating asymmetry in model III differs significantly than the one predicted by the standard model and model II which is a special case of model III. Furthermore, it is shown that the zero value of forward backward asymmetry A_{FB} is shifted when compared with the SM value, which can also serve as the efficiency tool for establishing new physics.

description: The analysis of the poles of the $ππ$ scattering amplitude is shown to favour a dynamical origin of the sigma meson: it is created by a strongly attractive $ππ$ interaction in the $J^{PC}=0^{++}I=0$ channel. In the limit $N_c\to\infty$, the $σ$ meson disappears, contrary to the case of conventional $q\bar{q}$ states. Implications for the search of the scalar $q\bar{q}$ and glueball states are discussed.

description: The magnetic field of a cuboidal cluster of eight magnetic spheres is measured. It decays with the inverse seventh power of the distance. This corresponds formally to a hitherto unheard-of multipole, namely a dotriacontapole. This strong decay is explained on the basis of dipole-dipole interaction and the symmetry of the ensuing ground state of the cuboidal cluster. A method to build such dotriacontapoles is provided.
Judith Butler et l'ontologie de la précarité. Repenser la vie en commun
Creators: name: BEUGRE, N'DRE SAM
Publisher: name: Zenodo
Year: 2023

description: La précarité révèle l'être dans son incomplétude. Judith Butler montre l'impossibilité d'être un à travers la notion hégélienne de sujet extatique. Le sujet ainsi défini se trouve projeté dans l'Autre — langage, normes sociales, regard extérieur —, ce qui entraîne un état de vulnérabilité : je dépends de ce que je ne suis pas pour être. Or, la vulnérabilité constitutive, loin d'être un déficit, peut se traduire en force, sans s'affranchir des limites qui la définissent, dans la mesure où elle interroge les illusions modernes d'autosuffisance et permet de découvrir et d'inventer la vie en commun. De même, loin de constituer la fin de l'éthique, elle engage radicalement les individus dans le monde qu'ils habitent.
European Industrial Energy Intensity: The Role of Innovation 1995-2009

description: We investigate the direct role of technological innovation and other influencing factors on industry-level energy intensity based on a sample of 12 industries across 17 EU countries over 1995–2009. We develop an innovative industry-level patent dataset and find compelling evidence that patent stock negatively influences industrial energy intensity. Using a fixed effects estimator, we find a much stronger effect on energy-intensive industries with an estimated coefficient of -0.138 almost double that of less energy-intensive industries (estimated at -0.085). While our results show energy price remains the major determinant of energy intensity, the chemicals industry appears to be more susceptible to energy prices relative to other energy-intensive industries that are covered by the EU Emissions Trading Scheme (ETS). Our study reveals that asymmetric response of energy intensity to energy prices in which price rises between 2004 and 2008 accounts for more change in efficiency than when prices fall. We also explore regional differences, notably that carbon tax policy in Northern European countries, which began in the early 1990s, is responsible for a significant fraction of the decline in energy intensity in Northern Europe.

description: The coherent and incoherent channels of the neutrinoless muon to electron conversion in nuclei, $μ^- (A,Z) \to e^- (A,Z)^*$, are studied throughout the periodic table. The relevant nuclear matrix elements are computed by explicitly constructing all possible final nuclear states in the context of the quasi-particle RPA. The obtained results are discussed in view of the existing at PSI and TRIUMF experimental data for $^{48}Ti$ and $^{208}Pb$ and compared with results obtained by: (i) shell model sum-rule techniques (ii) nuclear matter mapped into nuclei via a local density approximation and (iii) earlier similar calculations.

Mechanistic whole cell models of nitrogen metabolism in bacteria and their applications
Creators: name: Massie, Leanne
Publisher: name: Imperial College London
Year: 2022

description: Feeding the growing human population is a critical issue: one of the BBSRC's strategic research goals is increasing food security. Crop plants are limited in their ability to grow largely by a lack of bio-available nitrogen in the soil. Nitrogen fixing bacteria are one of the very few organisms able to fix atmospheric nitrogen into bioavailable forms by using the nitrogenase protein. A simulation of these bacteria is therefore of great interest for the biological modelling community and agricultural professionals to increase our understanding of these bacteria and to exploit their nitrogen fixing ability. In order to explore nitrogen metabolism generally, I have constructed a whole cell model of amino acid metabolism in bacteria and examined the applications of this amino acid model. I then go on to construct a separate whole cell model of nitrogenase in bacteria, both with and without amino acid metabolism. The end products of this thesis are three whole cell models: an amino acid model, a nitrogen fixing model, and a combined amino acid and nitrogen fixing model. It was found that there is a trade-off between the level of fixed nitrogen and the growth of the bacterial cell population, with a maximal yield of nitrogen occurring at high nitrogenase transcription levels and medium levels of transcription of metabolic proteins. These are the first nitrogen complete whole cell models available to the biological modelling community therefore I expect these models will improve future in silico experiments on bacteria and make their findings more translatable to the real world.
A Decade After Lehman: Taking Stock of Quantitative Easing and Regulation
Creators: name: Ramaswamy, R.
Publisher: name: Faculty of Economics
Year: 2018
Subjects: Quantitative Easing

deleveraging

description: The Lehman failure precipitated the Great Recession and forced economic policy into unchartered terrain. This paper provides a retrospective on the policy response and links to the underwhelming economic recovery. The exposition is kept non-technical to facilitate wider access. Contrary to perceptions that banks remain vulnerable, this paper argues that regulation strengthened U.S. banks across a variety of dimensions. The deleveraging involved in the transition to stronger banks tightened financial conditions and offset the significant monetary stimulus. The failure to fully capture these offsetting policy forces explains the systematic forecasting errors—both markets and the Fed have consistently overestimated the strength of the economic cycle. Quantitative Easing resulted in a ballooning of excess reserves in the banking system, but payment of interest on excess reserves helped bank recapitalisation. The combination of stronger banks and excess reserves has the potential, unlike in previous cycles, to drive a late cycle surge in growth.
An ultracold beam of YbF molecules for measuring the electron’s electric dipole moment
Creators: name: Swarbrick, Simon Christopher
Publisher: name: Imperial College London
Year: 2023

description: The observed matter-antimatter asymmetry of the universe remains unexplained and undiscovered sources of CP violation could yet prove to be its source. The electric dipole moment of leptons, strongly suppressed in the Standard Model, would be a source of CP violation and a sign of new physics. Recent measurements of the electron EDM have already pushed constraints on the energy range for new particles to be discovered beyond the reach of the LHC. This work focuses on the progress towards an experiment to measure the electron EDM using YbF. A buffer gas-cooled molecular source generates a pulsed beam of YbF molecules travelling at 180 m/s. Employing two-dimensional laser cooling, the transverse temperature of the beam drops below 200μK, significantly increasing its brightness by over two orders of magnitude compared to the uncooled beam. On average, each cooled beam pulse contains approximately 2x10^5 ultracold molecules. A hexapole magnetic lens will guide the molecular beam towards the cooling lasers. Simulations predict that the lens will enhance beam brightness by at least five-fold. Combined with transverse laser cooling, this magnetic lens has the potential to yield a beam three orders of magnitude brighter. This enhancement will enable a measurement of the electron EDM, with a statistical uncertainty of 2.2x10^(-31) e cm. This will represent an improvement of over an order of magnitude compared to the recent record established by JILA. Lastly, a new optical pumping scheme has been developed to transfer molecules from their laser cooling state to the absolute ground state of YbF, preparing for electron EDM measurement. This work lays the foundation for a high-precision measurement of the electron EDM using YbF.

description: Cybercrime, in the era of advanced technology, poses a significant threat to individuals and organizations, disrupting the fabric of global security and economic stability. The abstract examines the rise of cybercrime in the digital age, where criminals exploit the vulnerabilities of cyberspace to commit a wide range of offenses. The evolution of information technology has created a parallel world in cyberspace, offering opportunities and convenience to users, but it has also paved the way for malicious actors to exploit this interconnected network.

With the proliferation of netizens, the misuse of technology has led to a surge in cybercrime, both at domestic and international levels. In contrast to traditional physical crimes, modern cybercriminals can cause extensive damage and financial losses with the click of a button. This abstract highlights the economic toll of cybercrime, emphasizing the impact on individuals and businesses as criminals exploit vulnerabilities to steal, defraud, and compromise sensitive data. Cybersecurity measures have become crucial in safeguarding against these digital threats, protecting the global economy from this evolving challenge.
