Statistical scattering of waves in disordered waveguides: The limiting macroscopic statistics in the ballistic regime

description: In this work, we present a theoretical study of the statistical properties of wave scattering in a disordered ballistic waveguide of length L; we have called this system the "building block". The building block is interesting as a physical system because its statistical properties could be studied experimentally in the laboratory. In order to study the building block, as a physical system in itself, we have developed a perturbative method based on Born series. This method is valid only in the ballistic regime, when the length of the system L is smaller than the mean free path l, and in the short-wave-length approximation, when the the wave number k and the mean free path l satisfy kl >> 1. This method has allowed to find, analytically, the behavior of quantities of interest that we have not been able to find from the diffusion equation. In contrast with the diffusion equation method, which takes into account approximately the contribution of closed channels, this method takes them explicitly. In earlier works numerical evidence was found that the expectation values of some interesting quantities are insensitive to the number of closed channels that were used on the calculations; with this method, we could show that closed channels are relevant for the expectation values of amplitudes but irrelevant for the intensities and conductance expectation values. The results of this method show a good agreement with numerical simulations.

description: In the present paper, we handle the problem of finding a hypersurface family from a given asymptotic curve in R^4. Using the Frenet frame of the given asymptotic curve, we express the hypersurface as a linear combination of this frame and analyze the necessary and sufficient conditions for that curve to be asymptotic. We illustrate this method by presenting some examples.

description: There are many different semantics for general logic programs (i.e. programs that use negation in the bodies of clauses). Most of these semantics are Turing complete (in a sense that can be made precise), implying that they are undecidable. To obtain decidability one needs to put additional restrictions on programs and queries. In logic programming it is natural to put restrictions on the underlying first-order language.

description: La economía del desarrollo es la rama de la economía con la que nace el estudio moderno de la economía como ciencia. Adam Smith, considerado por muchos como el padre de la economía, formuló preguntas en el siglo XVIIIque nunca han dejado de interesar a las economistas. Las preguntas de Smith más relevantes para la economía del desarrollo son las relacionadas a las causas de la riqueza de las naciones y las políticas que la fomentan. Este curso introductorio ofrece una visión general de los principales temas de la economía del desarrollo. El carácter introductorio del curso permite que participen en él estudiantes de otras disciplinas distintas de la economía.El curso consta de cinco sesiones. Cada sesión dura dos horas académicas. Las clases se llevan a cabo usando un programa de reuniones virtuales (p. ej. Webex, Zoom, etc.) y un sistema de gestión de aprendizaje (p. ej. Blackboard, Moodle, etc.). Antes de la primera clase en el sistema de gestión de aprendizaje se comparten la sumilla y las lecturas obligatorias y sugeridas para que las estudiantes las puedan tener leídas antes de la clase. También se crea un foro de discusión para llevar a cabo una ronda virtual de presentación e intereses. En ella se presenta primero el facilitador del curso y éste les pide a los estudiantes que se presenten y escriban sobre sus intereses particulares en torno al tema.Al comenzar cada clase se comparte un enlace en el programa de reuniones virtuales con un video de la presentación magistral sobre el tema de la sesión. Luego de visto el video, la facilitadora organiza salas para grupos pequeños en el programa de reuniones virtuales con el fin de que las estudiantes respondan preguntas cuyas respuestas serán comentadas en la sesión plenaria luego de que los grupos hayan respondido las preguntas. El facilitador visita cada grupo para ayudar a las participantes a responder las preguntas. En la sesión plenaria voluntarios de cada grupo comparten sus respuestas y la facilitadora modera la discusión. Cada sesión termina con un comentario final dado por el facilitador

Populism, the Pandemic & Prospects for International Law

subject: 300 Sozialwissenschaften::340 Recht::340 Recht

description: Populism has fatally weakened the world’s ability to respond to COVID-19, by undermining the capacity of the structures and mechanisms of international law to address the pandemic. The pandemic has exposed as a fallacy a key tenet of populism – to protect the ‘people’ of a nation from external forces, including international law. In fact international law, through the principle of self-determination, enshrines the ability of peoples to determine their own political organization. But this does not preclude agreement at the international level on matters of common interest to humanity as a whole that require community action. The prevention of infectious disease is just such a case, which states have long agreed could not remain solely the preserve of national polities, but requires a common international response. This paper, placing the current crisis in light of the development of international health law, critically examines the response of key populist governments to COVID-19 in order to address the larger issue of the implications of populism for the fate of international law.

description: The precise knowledge of neutrino oscillation properties requires an accurate description of neutrino-nucleus interactions, constituting one of the largest source of current systematics. Accordingly, the development and implementation of sophisticated neutrino interaction models in the MonteCarlo event generators employed in neutrino oscillation experiments plays an essential role. In this context, the so-called SuSAv2-MEC model, based on the Relativistic Mean Field theory, has recently proven its validity to analyze neutrino-nucleus scattering data in the kinematical region of interest for current and forthcoming neutrino oscillation experiments, being a promising candidate to be implemented in event generators in order to improve the oscillation analysis. This work presents the first steps towards the implementation of sophisticated microscopic nuclear models (SuSAv2, RMF) in the NEUT event generator and the analysis of the low energy and nuclear-medium effects for several nuclei (C, O, Ar) in comparison with recent experimental analyses. https://www.youtube.com/watch?v=Yi6zdPCAQeY&feature=youtu.be
Application of Sediment Traps in Global Change Research in Mountain Lakes

Representativity of biota in the biosphere also have similar significance in the lithosphere after their death. Recently, taphonomic representation of biota in the lithosphere has been widely used for minimizing the biases in palaeo-environmental reconstructions including global climate change. In September 2001, a sediment trap was installed at the central area of the Loch Coire Fionnaraich (LCFR), a small, oligotrophic mountain loch in northwest Scotland for a taphonomic study of cladoceran zooplankton. The trap was emptied on a seasonal basis, where an average 0.14 g dry material was recovered in each season, January, May and August 2002 respectively. A sediment core was also taken from near the sediment trap location. The top 0.5 cm section, the 'core' was used for a comparative study with the trap sediment samples. The planktonic Cladocera consisted of Bosmina coregoni and appeared to have excellent preservation in the trap assemblages. Moreover, some common littoral Cladocera such as Alonella excisa and Alona guttata appear to be less well preserved in the fossil assemblages. Large littoral taxa such as Eurycercus lamellatus and Alona quadrangularis were rare in the trap but relatively common and well preserved in the sediment-water interface. It is suggested that taphonomic processes play a dominant role on deposition of fossil remains of Cladocera and caution should be taken while inferring the past environmental changes whilst using fossil assemblages recovered from the lake centre as a representation of the entire cladoceran community in the lake.

description: We numerically study the interplay between superconductivity and disorder on the graphene honeycomb lattice with on-site Hubbard attractive interactions U using a spatially inhomogeneous self-consistent Bogoliubov-de Gennes (BdG) approach. In the absence of disorder there are two phases at charge neutrality. Below a critical value Uc for attractive interactions there is a Dirac semimetal phase and above it there is a superconducting phase. We add scalar potential disorder to the system, while remaining at charge neutrality on average. Numerical solution of the BdG equations suggests that while in the strong attraction regime (U > Uc) disorder has the usual effect of suppressing superconductivity, in the weak attraction regime (U < Uc) weak disorder enhances superconductivity. In the weak attraction regime, disorder that is too strong eventually suppresses superconductivity, i.e., there is an optimal disorder strength that maximizes the critical temperature Tc. Our numerical results also suggest that in the weakly disordered regime, mesoscopic inhomogeneities enhance superconductivity significantly more than what is predicted by a spatially uniform mean-field theory a` la Abrikosov-Gorkov. In this regime, superconductivity consists of rare phase-coherent superconducting islands. We also study the enhancement of the superconducting proximity effect by disorder and mesoscopic inhomogeneities, and obtain typical spatial plots of the tunneling density of states and the superfluid susceptibility that can be directly compared to scanning tunneling miscroscopy (STM) experiments on proximity-induced superconductivity in graphene.

description: This is number nine of 42 preservation briefs prepared by the Technical Preservation Services of the National Park Service. This brief focuses on the repair of historic wooden windows. This Brief is based on the issues of significance and repair which are implicit in the standards, but the primary emphasis is on the technical issues of planning for the repair of windows including evaluation of their physical condition, techniques of repair, and design considerations when replacement is necessary. Much of the technical section presents repair techniques as an instructional guide for the do-it-yourselfer. The information will be useful, however, for the architect, contractor, or developer on large-scale projects. It presents a methodology for approaching the evaluation and repair of existing windows, and considerations for replacement, from which the professional can develop alternatives and specify appropriate materials and procedures.

The Barolo Palace: medieval astronomy in the streets of Buenos Aires

description: Cultural heritage relating to the sky in the form of sundials, old observatories and the like, are commonly found in many cities in the Old World, but rarely in the New. This paper examines astronomical heritage embodied in the Barolo Palace in Buenos Aires. While references to Dante Alighieri and his poetry are scattered in streets, buildings and monuments around the Western world, in the city of Buenos Aires, the only street carrying Dante's name is less than three blocks long and, appropriately, is a continuation of Virgilio street. A couple of Italian immigrants -a wealthy businessman, Luis Barolo, and an imaginative architect, Mario Palanti- foresaw this situation nearly a century ago, and did not save any efforts or money with the aim of getting Dante and his cosmology an appropriate monumental recognition, in reinforced concrete. The Barolo Palace is a unique combination of both astronomy and the worldview displayed in the Divine Comedy, Dante's poetic masterpiece. It is known that the Palace's design was inspired by the great poet, but the details are not recorded; this paper relies on Dante's text to consider whether it may add to our understanding of the building. Although the links of the Palace's main architectural structure with the three realms of the Comedy have been studied in the past, its unique astronomical flavor has not been sufficiently emphasized. The word of God, as interpreted by the Fathers of the Church in Sacred Scripture, Aristotle's physics and Ptolemy's astronomy, all beautifully converge in Dante's verses, and the Barolo Palace reflects this.

Reactivity of a ruthenium bis(dinitrogen) complex
Creators: name: Lau, Samantha
Publisher: name: Imperial College London
Year: 2018

description: This thesis investigated the reactivity of the ruthenium bis(dinitrogen) complex [Ru(H)2(N2)2(PCy3)2] (1), an analogue of the ruthenium bis(dihydrogen) complex [Ru(H)2(η2-H2)2(PCy3)2]. It was demonstrated that 1 was able to effect the sp2C–X (X= H, O) bond cleavage of acetophenone substrates to generate 5 membered organometallic intermediates. The by-products from the C–O cleavage reactions were identified as alcohols which also react with 1 at a faster or equal rate to the substrates. The mechanism of these C–X cleavage reactions were probed experimentally and computationally to show that the C–H bond cleavage pathway was operating through a σ-complex assisted metathesis pathway whereas the C–O cleavage pathway was operating through a Ru(II)/Ru(IV) redox mechanism. In addition, the reactivity of 1 with main group hydrides (aluminium, zinc and magnesium) was presented with the formation of a series of new ruthenium main group heterobimetallic hydride complexes, M•Ru (M = Al, Zn, Mg). These heterobimetallic hydride complexes contain either dinitrogen or dihydrogen ligated at the ruthenium centre depending on the partial pressure of N2 and H2 in the atmosphere. It was shown that the main group fragment can subtly tune the degree of dinitrogen activation in these M•Ru N¬2¬ complexes, Mg > Zn > Al. This trend was rationalised by probing the bonding and frontier molecular orbitals of these complexes. Furthermore, 27Al solid state NMR spectroscopy was implemented to analyse the ruthenium aluminium heterobimetallic hydride complexes and it was determined that that there was no linear correlation between the isotropic chemical shift obtained in the 27Al solid state NMR spectra and the oxidation state of the complex.

Extended periods of drawdown of reservoirs can result in the 'terrestrialization' of the lake bottom sediments, which describes the process whereby the exposed dry sediment takes on soil-like qualities. Opportunistic colonization of lake bed by terrestrial plants can occur under such conditions. A survey of plant communities of a large reservoir (Lake Hume) following its extreme drawdown, resulted in significant quantities of carbon, nitrogen and phosphorus being bound up in the terrestrial vegetation that colonized the lake bed. The phosphorus uptake from the sediment into plant material particularly could represent a significant pathway for phosphorus re-mobilization back into the lake. The potential of using stock grazing as a control measure for mitigating the effects of terrestrial plant colonization is also discussed.

description: Il Taccuino di Bonn, testimonianza preziosa, sino al 1891 del determinante soggiorno di Luigi Pi randello nella città tedesca, partecipa in modo particolarmente “avventuroso” delle vicissitudini redazionali che coinvolgono le carte private dello scrittore agrigentino. Restituito integralmente alla luce nella meritoria veste redazionale del 2022, il manoscritto pirandelliano si offre come «lo spazio in cui si deposita il magma creativo, a partire da dati e fatti, naturalistici e cronachistici, che si trasformano in rappresentazione e narra zione, in bozzetti lirici come in racconto in prosa e in versi» (R. Caputo, Prefazione a L. Pirandello, Taccuino di Bonn. Manoscritto, (a cura) di F. De Michele, C. A. Iacono, A. Perniciaro, Biblioteca Mu seo Regionale Luigi Pirandello, Parco Archeolo gico e Paesaggistico della Valle dei Templi, Agri gento 2022, p. 15». Il crogiuolo di temi e forme della poetica pirandelliana che così vi si condensa si configura, pertanto, come un’espressione ulte riormente esemplare dell’intertestualità interna che ne anima l’opera. Proprio sul fitto arsenale di tale “magazzino poietico”, sulla trama foltissima di riflessioni personali, di interpolazioni autoese getiche, di bilanci epocali di cui si sostanzia l’au tobiografismo intellettuale del taccuino, queste pagine intendono soffermarsi, per porre in risalto come sensibile ne appaia già l’inclinazione sulla “verticale del Novecento”.
description: The Taccuino di Bonn, a precious testimony until 1891 of Luigi Pirandello's decisive stay in the Ger man city, participates in a particularly "adven turous" way in the editorial vicissitudes involving the private papers of the writer from Agrigento. Restored to light in its entirety in the meritorious editorial guise of 2022, Pirandello's manuscript offers itself as "the space in which the creative magma is deposited, starting from data and facts, naturalistic and chronicle-like, which are trans formed into representation and narration, into lyrical sketches as well as into prose and verse narratives". The melting pot of themes and forms of Pirandello's poetics that is condensed here is thus configured as a further exemplary expression of the internal intertextuality that animates his work. It is precisely on the dense arsenal of this "poietic storehouse", on the dense weave of per sonal reflections, of self-exegetic interpolations, of epochal balances that substantiate the notebook's intellectual autobiographism, that these pages in tend to dwell, to highlight how sensitive its incli nation towards the "vertical of the twentieth cen tury" already appears.

Structural and dynamical analysis of ionic liquids in electric fields
Creators: name: Clark, Ryan Ashley Arthur
Publisher: name: Imperial College London
Year: 2020

description: Molecular rotors and molecular dynamics simulations are used to study changes in the structure and dynamics of ionic liquids in the presence of external electric fields. The immediate environment around the rotors is elucidated in the absence of the electric field from a study of the behaviour of the dyes in various ionic liquids. Using this knowledge, the effect of an electrode upon an ionic liquid at various depths was investigated by studying the change in the rotor properties upon application of a potential. This showed remarkable effects of an electrode upon the rotor properties up to 50 micrometres away from the electrode which persisted for over one hour. To attempt to rationalise these results, molecular dynamics simulations were performed on two ionic liquids in electric fields, and their structure and dynamics were studied over a range of electric fields. Particular focus was put onto the charge arm concept, as a replacement for the dipole in an ion. This was able to rationalise changes in the structure of the ion that were difficult to explain otherwise, such as changes to the conformation and rotation of the ions.

description: This paper reports the study of growth kinetics of ion beam sputtered aluminum thin films. Dynamic scaling theory was used to derive the kinetics from AFM measurements. AFM imaging revealed that surface incorporates distinctly different morphologies. Variation in deposition times resulted in such distinctiveness. The growth governing static (alpha) as well as dynamic (beta) scaling exponents have been determined. The exponent (alpha) decreased as the deposition time increased from 3 to 15 minutes. Consequently, the interfacial width (xi) also decreased with critical length (Lc), accompanied with an increase in surface roughness. Surface diffusion becomes a major surface roughening phenomenon that occurs during deposition carried out over a short period of 3 minutes. Extension of deposition time to 15 minutes brought in bulk diffusion process to dominate which eventually led to smoothening of a continuous film.

description: The Potts model plays an essential role in classical statistical mechanics, illustrating many fundamental phenomena. One example is the existence of partially long-range-ordered states, in which some degrees of freedom remain disordered. This situation may arise from frustration of the interactions, but also from an irregular but unfrustrated lattice structure. We study partial long-range order in a range of antiferromagnetic $q$-state Potts models on different two-dimensional lattices and for all relevant values of $q$. We exploit the power of tensor-based numerical methods to evaluate the partition function of these models and hence to extract the key thermodynamic properties -- entropy, specific heat, magnetization, and susceptibility -- giving deep insight into the phase transitions and ordered states of each system. Our calculations reveal a range of phenomena related to partial ordering, including different types of entropy-driven phase transition, the role of lattice irregularity, very large values of the critical $q_c$, and double phase transitions.

Evaluating the opportunities for image guidance as a surgical decision-support technology to improve the quality and safety of surgery
Creators: name: Dilley, James
Publisher: name: Imperial College London
Year: 2019

description: Image guidance has been developed to improve and augment the visual input to the surgeon before and during surgical procedure. Despite much interest and research it is not yet commonplace in operating theatres or surgical workflow. This thesis sought to understand the current landscape and provide evidence for future direction and integration of image guidance systems. An initial systematic review demonstrated how existing clinical image guidance systems focused their reported outcomes on traditional clinical measures, commonly neglecting to report on areas that image guidance were designed to improve, namely user interaction as well as patient acceptability and economic impact Within a simulated environment it was shown that image guidance allows the surgeon to perform a laparoscopic cholecystectomy more accurately. However, it was surgeons using a low-barrier image guidance system based on preoperative images rather than perfectly registered intraoperative system that experienced better surgical outcomes. A second study demonstrated that surgeon’s behaviour is unaltered between the simulated and real robotic environments. This validated the simulated robotic environment as a platform in which image guidance can be developed as well as the use of eye metrics as an objective measure of surgeon behaviour. The second part of the thesis explored image guidance in the preoperative workflow setting. After initially confirming the importance of imaging to surgeons in planning and predicting complications, two studies were performed. The first of these demonstrated that surgeons using an image guidance platform were more accurately able to predict the surgical procedures and complexity required to achieve their surgical aim. The second found that as the complexity of the cases increases, those using the image guidance system were more accurate in identifying the anatomy that was affected or involved. Importantly in both of these studies the surgeon’s mental workload was reduced. This thesis has demonstrated that image guidance can improve surgical outcomes and benefit the surgeon. Improving publication focus, leveraging the simulated environment and expanding use of image guidance into the preoperative workflow are key components towards realizing its translation as a surgical decision-support technology to improve the quality and safety of surgery.
