description: The class of relativistic spin particle models reveals the `quantization' of parameters already at the classical level. The special parameter values emerge if one requires the maximality of classical global continuous symmetries. The same requirement applied to a non-relativistic particle with odd degrees of freedom gives rise to supersymmetric quantum mechanics. Coupling classical non-relativistic superparticle to a `U(1) gauge field', one can arrive at the quantum dynamical supersymmetry. This consists in supersymmetry appearing at special values of the coupling constant characterizing interaction of a system of boson and fermion but disappearing in a free case. Possible relevance of this phenomenon to high-temperature superconductivity is speculated.

description: Glioma grading before surgery is very critical for the prognosis prediction and treatment plan making. We present a novel wavelet scattering-based radiomic method to predict noninvasively and accurately the glioma grades. The method consists of wavelet scattering feature extraction, dimensionality reduction, and glioma grade prediction. The dimensionality reduction was achieved using partial least squares (PLS) regression and the glioma grade prediction using support vector machine (SVM), logistic regression (LR) and random forest (RF). The prediction obtained on multimodal magnetic resonance images of 285 patients with well-labeled intratumoral and peritumoral regions showed that the area under the receiver operating characteristic curve (AUC) of glioma grade prediction was increased up to 0.99 when considering both intratumoral and peritumoral features in multimodal images, which represents an increase of about 13% compared to traditional radiomics. In addition, the features extracted from peritumoral regions further increase the accuracy of glioma grading.

description: The 22 GHz H_2O masers in the circumstellar envelope of the Mira variable star U Her have been observed with MERLIN using a phase referencing technique to determine accurate astrometric positions. The positions were compared with the optical positions obtained with the Hipparcos satellite to an accuracy of 18 mas. The absolute radio position of the brightest H_2O maser spot is found to match the optical position, indicating that this spot is the stellar image amplified by the maser screen in front of it. The occurrence of an amplified image in the 22 GHz maser can be used to accurately determine the positions of the H_2O with respect to the star as well as with respect to the SiO and OH masers. Our observations seem to indicate that the star is not in the centre of the distribution of maser spots, which has been interpreted as a ring.

description: The Megleno-Romanians, who constitute a separate branch of the Latin-speaking peoples ofEastern Europe, originated in northern Greece. They emigrated to Romania at the start of thetwentieth century. From a cultural perspective, the Megleno-Romanians are to be distinguishedfrom other neighbouring ethnic populations on the basis of their dialect, religion, and history. TheMegleno-Romanians’ characteristic modes of thought and action distinguish them from theAromanians. Meanwhile their creative instinct has manifested itself in artistic productions of nolittle originality, productions which are assured a place within the national cultural heritage. Ourstudy of authentic Megleno-Romanian songs has led us the conclusion that the Megleno-Romanianrepertoire in the village of Cerna is, to a very large extent, composed in their own dialect. Thisfinding leads us to believe that there has always existed within the family context a pure, Megleno-Romanian repertoire which has survived and developed through oral transmission.

description: Self-testing is a method to infer the underlying physics of a quantum experiment in a black box scenario. As such it represents the strongest form of certification for quantum systems. In recent years a considerable self-testing literature has been developed, leading to progress in related device-independent quantum information protocols and deepening our understanding of quantum correlations. In this work we give a thorough and self-contained introduction and review of self-testing and its application to other areas of quantum information.

Swift prosodic modulation of lexical access (Hjortdal et al., 2024)

subject: Psycholinguistics (incl. speech production and comprehension)

description: Purpose: According to most models of spoken word recognition, listeners probabilistically activate a set of lexical candidates, which is incrementally updated as the speech signal unfolds. Speech carries segmental (speech sound) as well as suprasegmental (prosodic) information. The role of the latter in spoken word recognition is less clear. We investigated how suprasegments (tone and voice quality) in three North Germanic language varieties affected lexical access by scrutinizing temporally fine-grained neurophysiological effects of lexical uncertainty and information gain.Method: Three event-related potential (ERP) studies were reanalyzed. In all varieties investigated, suprasegments are associated with specific word endings. Swedish has two lexical “word accents” realized as pitch falls with different timings across dialects. In Danish, the distinction is in voice quality. We combined pronunciation lexica and frequency lists to calculate estimates of lexical uncertainty about an unfolding word and information gain upon hearing a suprasegmental cue and the segment upon which it manifests. We used single-trial mixed-effects regression models run every 4 ms.Results: Only lexical uncertainty showed solid results: a frontal effect at 150–400 ms after suprasegmental cue onset and a later posterior effect after 200 ms. While a model including only segmental information mostly performed better, it was outperformed by the suprasegmental model at 200–330 ms at frontal sites.Conclusions: The study points to suprasegmental cues contributing to lexical access over and beyond segments after around 200 ms in the North Germanic varieties investigated. Furthermore, the findings indicate that a previously reported “pre-activation negativity” predominantly reflects forward-looking processing.Supplemental Material S1.

Education--Sociological aspects

description: A central feature of modern government is its role in designing welfare improving policies to address and correct market failures stemming from externalities and public goods. The rationale for most modern environmental regulations stems from the failure of markets to efficiently allocate goods and services. Yet, as with any policy, distributional effects are important there exist clear winners and losers. Despite the clear theoretical justification for environmental and energy policy, empirical work credibly identifying both the source and consequences of these externalities as well as the distributional effects of existing policies remains in its infancy. My dissertation focuses on the development of empirical methods to investigate the role of environmental and energy policy in addressing market failures as well as exploring the distributional implications of these policies. These questions are important not only as a justification for government intervention into markets but also for understanding how distributional consequences may shape the design and implementation of these policies. My dissertation investigates these questions in the context of programs and policies that are important in their own right. Chapters 1 and 2 of my dissertation explore the economic costs and distributional implications associated with the largest environmental regulatory pro- gram in the United States, the Clean Air Act. Chapters 3 and 4 examine the social costs of air pollution in the context of transportation externalities, showing how effective transportation policy has additional co-benefits in the form of environmental policy. My dissertation remains unified in both its subject matter and methodological approach - using unique sources of data and sound research designs to understand important issues in environmental policy.
A [CII]-158-micron Survey of DLA galaxies at z~4: Observations of Dense and Metal-Enriched Neutral Gas within the Circumgalactic Medium of Star-Forming Galaxies

description: We present a survey undertaken with the Atacama Large Millimeter/submillimeter Array (ALMA) to study the galaxies associated with a representative sample of 16 damped Ly-alpha absorbers (DLAs) at z~4.1-4.5, using the [CII]-158-micron ([CII]) line. We detect seven [CII]-emitting galaxies in the fields of 5 DLAs, all of which have absorption metallicity [M/H] > -1.5. We find that the detectability of these HI-selected galaxies with ALMA is a strong function of DLA metallicity, with a detection rate of 71^{+11}_{-20}% for DLAs with [M/H] > -1.5 and 0^{+18}% for DLAs with [M/H] <-1.5. The identified DLA galaxies have far-infrared properties similar to those of typical star-forming galaxies at z ~ 4, with estimated obscured star-formation rates ranging from ~6 Msun/yr to 110 Msun/yr. High-metallicity DLAs therefore provide an efficient way to identify and study samples of high-redshift, star-forming galaxies without preselecting the galaxies by their emission properties. The agreement between the velocities of the metal absorption lines of the DLA and the [CII] emission line of the DLA galaxy indicates that the metals within the DLA originated in the galaxy. With observed impact parameters between 14 and 59 kpc, this indicates that star-forming galaxies at z ~ 4 have a substantial reservoir of dense, cold neutral gas within their circumgalactic medium that has been enriched with metals from the galaxy.

description: Since a number of school fire accidents occurred in 2002, the Saudi Arabian government has realised that providing school safety regulations is necessary in order to avoid accidents in the nation’s schools. The Saudi Ministry of Education has been actively seeking to develop applicable regulations to measure the safety performance of each school. Nowadays, school safety has become an important topic for all Saudi parents, especially parents of children who are just starting school for the first time; it also has become an important priority for the Saudi Minister of Education. For this reason, the Minister, in 2012, issued an important decision to develop an administrative unit, under the name of Schools Security and Safety Administration, to achieve the following goals: provide a safe and healthy environment in schools; prevent accidents or injuries during school hours; control school accidents and emergencies; provide necessary information and instructions to know the risks that students and staff may face at school and guide them on methods of prevention; contribute to educating students on the safety aspects in their schools; and finally, document accidents and injuries for the purpose of evaluating school safety processes. Kaplan and Norton (1992) developed an innovative performance management system that includes three core subsystems, namely, a measurement system, a strategic management system and a communication system. This performance management system, called a balanced scorecard (BSC), showed great potential to be adapted to enable the Saudi Ministry of Education to meet its need for effective safety performance at each school. Therefore, the study’s key aim was to develop a BSC, which includes diverse perspectives for evaluating the various leading and lagging indicators of safety performance in Saudi schools.

description: Systems Biology and Bioinformatics have emerged as scientific fields as a consequence of our increasing capacity to use systems-wide technologies to understand biology. However, the internal scales of Systems Biology and Bioinformatics are currently unbalanced: informatically obese and biologically anorexic. The scale of information collected in a single experiment is now vast, but very often the use is limited. Producing meaning from this data has not been elevated to the same level as data collection and so by comparison our understanding of biology remains relatively anorexic. How best to deal with large amounts of gene expression data has been a research topic of nearly two decades. This research has provided improvements to technologies, processing algorithms and the understanding of the translation of genome to transcriptome. However, it remains that the current and interwoven challenges for understanding biology are; (i) to invent technologies that can determine how the genome is used; (ii) to identify and validate biological mechanisms, and; (iii) to provide meaning to data collected in a high-throughput biologically driven experiment. The focus of this thesis is to provide context to data collected from high-throughput gene expression experiments related specifically to striated muscle.

It is shown that their (appropriately adapted) method is applicable to a large class of mechanical models with a semisimple gauge group in the adjoint and fundamental representation. This includes cases where the Faddeev-Popov method fails. Simple models are found also, however, which do not allow for a well-defined global extension of the Batalin-Marnelius inner product due to a Gribov obstruction. Reasons for the partial success and failure are worked out and possible ways to circumvent the problem are briefly discussed.

ABSTRACT Although Artabanos II, king of Parthia (ca. AD 10/11-39/40) had scored substantial successes in his endeavour to consolidate the Parthian Empire and in his Roman policy (to gain control of Armenia), he had not managed to definitively resolve the issue of succession. This was a difficult task at the time, since the authority of Parthia’s central power relied very substantially on the potential of the sundry political factions, which were powerful enough jointly and severally to depose their King of Kings. The main factions fighting for supremacy in Parthia in the first half of the 1st century AD were the Hyrcanian-Dahaean, the Atropatenian, and the Phraatid (including the Sūrēn and Kārin clans) parties. Artabanos II managed to eliminate the Sūrēn clan from the power struggle in the Imperium Parthicum, but he failed to effect a lasting collapse of the Phraatid party, supporting the progeny of Phraates IV (37-4 BC). Moreover, his death in AD 39 or 40 meant the disintegration of the coalition of two of the major forces, the Hyrcanian-Dahaean faction and the Atropatenian faction. Their representatives, Gotarzes II (supported by the Dahae and Hyrcanians) and Vardanes (from Media Atropatene) pounced on one another. The extent of the territories on which their battles were fought was remarkably broad – from Babylonia and Armenia to Bactria and Chorasmia/Khorezm – and engaged the forces of a diversity of vassal kingdoms, satrapies, large cities such as Seleukeia on the Tigris, Susa, Charax Spasinou, Ktesiphon, and Babylon, not to mention neighbouring powers like the Kushans and Indo-Parthians.
Essays on Exchange Rates and Emerging Markets

description: This dissertation consists of three essays on exchange rates and international finance with an emphasis on emerging economies. In Chapter 1, I provide empirical evidence that supports the hypothesis that exchange rate based stabilization programs are expansionary during their early phases. I derive a new set of stabilization episodes using extensive country chronologies from Reinhart and Rogoff (2004) and I find that even after controlling for external conditions, the initial expansion associated with the introduction of an exchange rate based program, is caused by both, the program itself and positive external conditions. These expansionary effects are robust to different estimation methods and different criteria for detecting stabilization episodes. In Chapter 2, I study the relationship between foreign interest rates, country spreads, terms of trade and macro fundamentals in emerging markets. I estimate a structural VAR for 15 emerging economies. I find that country spreads explain 12% of output fluctuations, foreign interest rates an additional 7% and the terms of trade about 5%. I also find that country spreads account for a quarter of real exchange rate variability while the terms of trade account for just 1%. To further validate these results, I develop a dynamic stochastic general equilibrium (DSGE) model for a small open economy. The model incorporates several open economy frictions: i) bond-holding adjustment costs, ii) investment adjustment costs, iii) a working capital constraint, and iv) a country spread component that depends upon macro fundamentals, which is taken from the estimated VAR. The model is able to replicate fairly good the propagation effects of foreign rates and country spread shocks but overestimates the importance of the terms of trades. In Chapter 3, I investigate the relation between volatility in the foreign exchange market and excess returns on carry trade portfolios for the G10 currencies. I develop and compare three different investment strategies that aim at avoiding losses when volatility jumps, a common feature of the carry trade. I find that two trading strategies, one based on implied volatility from FX options and the other on exponentially-weighted moving averages, provide better risk-adjusted returns than the standard carry trade. A third strategy, based on Markov-switching exchange rate forecasts, provides excess returns for some currencies but fails for portfolios of currencies. I also show that currency investing provides superior Sharpe ratios than a benchmark bond portfolio and a benchmark stock portfolio, even after including the recent global financial crisis.

description: The concept of logarithmic representation of infinitesimal generators is introduced, and it is applied to clarify the algebraic structure of bounded and unbounded infinitesimal generators. In particular, by means of the logarithmic representation, the bounded components can be extracted from generally-unbounded infinitesimal generators. In conclusion the concept of module over a Banach algebra is proposed as the generalization of Banach algebra. As an application to mathematical physics, the rigorous formulation of rotation group, which consists of unbounded operators being written by differential operators, is provided using the module over a Banach algebra.

A data base of accurately measured stellar profiles will be needed to correctly subtract the stellar flux in planetary transient events. The amount of data that is being and will be produced in current and future microlensing surveys, from the space and the ground, requires algorithms that can quickly compute light curves for different source-lens configurations. Based on the convolution method we describe a general formalism to compute those curves for single lenses. We develop approximations in terms of quadratures of elliptic integrals that we integrate by solving the associated first order differential equations. We construct analytic solutions for a limb darkening and, for the first time, for a parabolic profile that are accurate at the $\sim 1-3\%$ and $0.5\%$ level, respectively. These solutions can be computed orders of magnitude faster than other integration routines. They can be implemented in pipelines processing large data sets to extract stellar parameters in real time.

description: In the era of climate change, there is an increased interest in including different types of green infrastructure in building legislation as a strategy to improve the built environment. Among these different types, trees on buildings have received little attention, and there is limited literature and policies to guide their design and implementation. Therefore, this research aims to explore trees on buildings from various perspectives to enrich the scholarship and policies and to enable their implementation. To achieve this, the research includes a four-stage mixed method using qualitative and quantitative approaches.

description: Underwater quantum key distribution (QKD) has potential applications in absolutely secure underwater communication. However, the performance of underwater QKD is limited by the optical elements, background light, and dark counts of the detector. In this paper, we propose a modified formula for the quantum bit error rate (QBER), which takes into account the effect of detector efficiency on the QBER caused by the background light. Then we calculate the QBER of the polarization encoding BB84 protocol in Jerlov type seawater by analyzing the effect of the background light and optical components in a more realistic situation. Finally, we further analyze the final key rate and the maximum secure communication distance in three propagation modes, i.e., upward, downward and horizontal modes. We find that secure QKD can be performed in the clearest Jerlov type seawater at a distance of hundreds of meters, even in the worst downward propagation mode. Specifically, by optimizing the system parameters, it is possible to securely transmit information with a rate of 67kbits/s at a distance of 100 m in the seawater channel with an attenuation coefficient of 0.03/m at night. For practical underwater QKD, the performance can also be improved by using decoy states. Our results are useful to long distance underwater quantum communication.

description: Uncontrolled proliferation is a fundamental trait that defines all malignant neoplasms. The acquisition of such ability for unrestrained growth is governed by mechanisms encompassing a multitude of complementary molecular events that include somatic mutations, epigenetic alterations, and constant phenotypic changes driven by the ever changing tumour microenvironment. In time, while going through the evolutionary process of tumourigenesis, tumours acquire and adapt unique sets of these molecular events driving proliferation and growth. As a result, a multitude of growth pathways, each unique in its molecular makeup, yet similar in conferring unlimited proliferative capacity can potentially arise. A major challenge therefore is to establish a way to pinpoint the specific molecular alterations actively driving proliferation and tumour growth. In this study, we design a method that has the ability to detect and isolate the proliferating tumour cells for their molecular characterisation.
Material slow and fast light in a zero-dispersion configuration

description: We study the propagation of light pulses in an absorbing medium when the frequency of their carrier coincides with a zero of the refractive index dispersion. Although slow light and, a fortiori, fast light are not expected in such conditions, we show that both can be obtained by selecting particular phase-components of the transmitted field. Analytical expressions of the resulting signals are obtained by a procedure of periodic continuation of the incident pulse and a proof of principle of the predicted phenomena is performed by means of a very simple electrical network, the transfer function of which mimics that of the medium.
3-D TRAVEL TIME TOMOGRAPHY INVERSION FOR GAS HYDRATE DISTRIBUTION FROM OCEAN BOTTOM SEISMOMETER DATA

description: This paper presents results of a seismic tomography experiment carried out at the Bullseye cold vent site offshore Vancouver Island. In the experiment, a seismic air gun survey was recorded on an array of five ocean bottom seismometers (OBS) deployed around the vent. The locations of the shots and the OBSs were determined to high accuracy by an inversion based on the shot travel times. A three-dimensional tomographic inversion was then carried out to determine the velocity structure around the vent, using the localized source and receiver positions. The inversion indicates a relatively uniform velocity field around and inside the vent. The velocities are close to the values expected for sediments containing no hydrate, which supports previous claims that the bulk concentrations of gas hydrates are low at the site. However, the largest resolved velocity anomalies of + 25 m/s are spatially within the limits of the acoustic blank zone seen in multichannel seismic data near the Bullseye vent. The velocity inversion is consistent with zones of high concentration (15-20 % of the pore space) in the top 50-100 m of sediment.

description: In this paper, we consider local holomorphic mappings f: M\to M' between real algebraic CR generic manifolds (or more generally, real algebraic sets with singularities) in the complex euclidean spaces of different dimensions and we search necessary and sufficient conditions for f to be algebraic. These conditions appear to exclude two certain flatness of M and of M'. From the point of view of CR geometry, a real analytic CR manifold M can be flat in essentially to ways, being biholomorphic to a product M_1\times Δ^k, k\geq 1, by a polydisc (algebraic degeneracy), or to a product M_1\times I^l,l\geq 1 by a real cube (transversal degeneracy), in a neighborhod of a Zariski generic point. We also require that the CR manifold M is minimal in the sense of Tumanov at a generic point. Our first result provides a characterization of mappings with positive transcendence degree k. Such maps have the property that near a Zariski generic point f(p) in M', there exists a k-algebraically degenerate real algebraic set X'' which contains f(M) and which is contained in M'. This solves the algebraic mapping problem for a minimal source M completely. Our second main result is the construction of canonical foliations by Segre surfaces of the extrinsic complexification of M. We prove in particular that a holomorphic function defined in a neighborhood of a minimal M is algebraic if and only if its restriction to each Segre surface of M is algebraic. We also show by an example that the double reflection foliation in the spirit of tangential CR derivations does not yield a characterization of positivity of transcendence degree of holomorphic mappings.

description: ECH capacities were developed by Hutchings to study embedding problems for symplectic $4$-manifolds with boundary. They have found especial success in the case of certain toric symplectic manifolds where many of the computations resemble calculations found in cohomology of $\mathbb{Q}$-line bundles on toric varieties, or in lattice point counts for rational polytopes. We formalise this observation in the case of convex toric lattice domains $X_Ω$ by constructing a natural polarised toric variety $(Y_{Σ(Ω)},D_Ω)$ containing the all the information of the ECH capacities of $X_Ω$ in purely algebro-geometric terms. Applying the Ehrhart theory of the polytopes involved in this construction gives some new results in the combinatorialisation and asymptotics of ECH capacities for convex toric domains.

description: This paper is devoted to represent a complete classification of space curves under affine transformations in the view of Cartan’s theorem. Spivak has applied the method without trying to complite the problem and to find the invariants. Furthermore, we propose a necessary and sufficient condition for the invariants and suggest their applications in physics, computer vision and image processing.

description: We simulate numerically the surface flow of a gas-supplying companion star in a semi-detached binary system. Calculations are carried out for a region including only the mass-losing star, thus not the mass accreting star. The equation of state is that of an ideal gas characterized by a specific heat ratio gamma, and the case with gamma=5/3 is mainly studied. A system of eddies appears on the surface of the companion star: an eddy in the low pressure region near the L1 point, one around the high pressure at the north pole, and one or two eddies around the low pressure at the opposite side of the L1 point. Gas elements starting near the pole region rotate clockwise around the north pole (here the binary system rotates counter-clockwise as seen from the north pole). Because of viscosity, the gas drifts to the equatorial region, switches to the counter-clockwise eddy near the L1 point and flows through the L1 point to finally form the L1 stream. The flow field in the L1 region and the structure of the L1 stream are also considered.
