description: Broadband tomography statistically extracts the redshift distribution of frequency dependent emission from the cross correlation of intensity maps with a reference catalog of galaxy tracers. We make forecasts for the performance of future all-sky UV experiments doing broadband tomography. We consider the Cosmological Advanced Survey Telescope for Optical-UV Research (CASTOR) and the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx). We show that under reasonable error models, CASTOR measures the UV background SED 2-10 times better than existing data. It will also expand the applicable redshift range from the current z < 1 to z~0-3 with CASTOR and z=5-9 with SPHEREx. We show that CASTOR can provide competitive constraints on the EBL monopole to those available from galaxy number counts and direct measurement techniques. At high redshift especially, these results will help understand galaxy formation and reionization. Our modelling code and chains are publicly available.

On the space of elliptic genera

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Invariance under modular transformations and spectral flow restrict the possible spectra of superconformal field theories (SCFT). This paper presents a technique to calculate the number of constraints on the polar spectra of N=(2,2) and N=(4,0) SCFT's by analyzing the elliptic genus. The polar spectrum corresponds to the principal part of a Laurent expansion derived from the elliptic genus. From the point of view of the AdS_3/CFT_2 correspondence, these are the states which lie below the cosmic censorship bound in classical gravity. The dimension of the space of elliptic genera is obtained as the number of coefficients of the principal part minus the number of constraints. As an additional illustration of the technique, the constraints on the spectrum of N=4 topologically twisted Yang-Mills on CP^2 are discussed.

description: Due to its favorable conditions the area of the middle Orontes around the provincial capital Hama is one of the main settlement areas in western Syria. Archaeological surface prospecting carried out between 2003 and 2005 demonstrates the continuous use of this landscape since the Paleolithic period. In addition to numerous single period sites from the prehistoric periods, the settlement pattern comprises a number of large tall settlements, mostly located near the river valley of the Orontes and its tributary Sarut. Archaeological evidence indicates a high settlement density in the early and middle Bronze Age as well as the Roman/early Byzantine periods.

description: The concept of descent algebras over a field of characteristic zero is extended to define descent algebras over a field of prime characteristic. Some basic algebraic structure of the latter, including its radical and irreducible modules, is then determined. The decomposition matrix of the descent algebras of Coxeter group types $A$, $B$, and $D$ are calculated, and used to derive a description of the decomposition matrix of an arbitrary descent algebra. The Cartan matrix of a variety of descent algebras over a finite field is then obtained.

description: The 10 m high Copper Age settlement mound of Pietrele-Măgura Gorgana, situated close to the Danube was part of a large settlement system spread over the whole Westpontic region during the 5th millennium BC. The mound was the outstanding part of a far more complex and larger flat settlement as we now know thanks to geomagnetic prospections and subsequent excavations. Only recently it became evident that the oldest parts of the flat settlement belong into the late 6th millennium. Around 1000 years settlement history (5200–4250 BC) offers insight into one of the most dynamic periods in human history coined by first metallurgical activities. During the settlement period a lake covered huge parts of the floodplain. It provided not only a considerable part of the diet, but ensured continuous and extensive regional exchange. Sedimentological and paleo ecological research gave evidence that the paleo lake started to exist from early to mid-Holocene onward until it was subdivided in smaller lakes by prograding branches of the Danube about 1000 years ago. The ecological conditions within the lake changed considerably, which can be deduced from geochemical, paleo botanical and microe faunistic analyses and which might be attributed to human impact during the settlement period. This was corroborated by studies on the former landscape around the settlement mound of Pietrele and the geomorphological processes induced by land use and settlement activities.

description: In 2013 research work in Baalbek had to be re-organized due to increasing political crises in the wider region. In close cooperation with Lebanese researchers, an excavation in the famous quarry in the south of Baalbek has been carried out aiming at collecting hints for quarrying and transportation techniques for the monumental blocks. Unexpectedly, an even larger block came to light that has to be considered the largest block ever cut in antiquity. Between 2001 and 2011 a comprehensive research project was carried out in Baalbek for the documentation of excavated but not yet published archaeological architectural remains and findings. It aimed at investigating the urban development of the town from its beginning until present. Parts of its results have been published and made public in a WebGIS. In addition, a feasibility study for conservation work has been developed.

description: The Southern Photometric Local Universe Survey (S-PLUS) is an ongoing survey of $\sim$9300 deg$^2$ in the southern sky in a 12-band photometric system. This paper presents the second data release (DR2) of S-PLUS, consisting of 514 tiles covering an area of 950 deg$^2$. The data has been fully calibrated using a new photometric calibration technique suitable for the new generation of wide-field multi-filter surveys. This technique consists of a $χ^2$ minimisation to fit synthetic stellar templates to already calibrated data from other surveys, eliminating the need for standard stars and reducing the survey duration by $\sim$15\%. We compare the template-predicted and S-PLUS instrumental magnitudes to derive the photometric zero-points (ZPs). We show that these ZPs can be further refined by fitting the stellar templates to the 12 S-PLUS magnitudes, which better constrain the models by adding the narrow-band information. We use the STRIPE82 region to estimate ZP errors, which are $\lesssim10$ mmags for filters J0410, J0430, $g$, J0515, $r$, J0660, $i$, J0861 and $z$; $\lesssim 15$ mmags for filter J0378; and $\lesssim 25$ mmags for filters $u$ and J0395. We describe the complete data flow of the S-PLUS/DR2 from observations to the final catalogues and present a brief characterisation of the data. We show that, for a minimum signal-to-noise threshold of 3, the photometric depths of the DR2 range from 19.9 mag to 21.3 mag (measured in Petrosian apertures), depending on the filter.

description: We consider two-species of fermions in a rotating trap that interact via an s-wave Feshbach resonance, at total Landau level filling factor two (or one for each species). We show that the system undergoes a quantum phase transition from a fermion integer quantum Hall state to a boson fractional quantum Hall state as the pairing interaction strength increases, with the transition occurring near the resonance. The effective field theory for the transition is shown to be that of a (emergent) massless relativistic bosonic field coupled to a Chern-Simons gauge field, with the coupling giving rise to semionic statistics to the emergent particles.

description: We propose a learning system in which language is grounded in visual percepts without specific pre-defined categories of terms. We present a unified generative method to acquire a shared semantic/visual embedding that enables the learning of language about a wide range of real-world objects. We evaluate the efficacy of this learning by predicting the semantics of objects and comparing the performance with neural and non-neural inputs. We show that this generative approach exhibits promising results in language grounding without pre-specifying visual categories under low resource settings. Our experiments demonstrate that this approach is generalizable to multilingual, highly varied datasets.

description: Deep learning-based video manipulation methods have become widely accessible to the masses. With little to no effort, people can quickly learn how to generate deepfake (DF) videos. While deep learning-based detection methods have been proposed to identify specific types of DFs, their performance suffers for other types of deepfake methods, including real-world deepfakes, on which they are not sufficiently trained. In other words, most of the proposed deep learning-based detection methods lack transferability and generalizability. Beyond detecting a single type of DF from benchmark deepfake datasets, we focus on developing a generalized approach to detect multiple types of DFs, including deepfakes from unknown generation methods such as DeepFake-in-the-Wild (DFW) videos. To better cope with unknown and unseen deepfakes, we introduce a Convolutional LSTM-based Residual Network (CLRNet), which adopts a unique model training strategy and explores spatial as well as the temporal information in deepfakes. Through extensive experiments, we show that existing defense methods are not ready for real-world deployment. Whereas our defense method (CLRNet) achieves far better generalization when detecting various benchmark deepfake methods (97.57% on average). Furthermore, we evaluate our approach with a high-quality DeepFake-in-the-Wild dataset, collected from the Internet containing numerous videos and having more than 150,000 frames. Our CLRNet model demonstrated that it generalizes well against high-quality DFW videos by achieving 93.86% detection accuracy, outperforming existing state-of-the-art defense methods by a considerable margin.

Origin of multiple stellar populations in globular clusters and their helium enrichment
Creators: name: Renzini, Alvio
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The various scenarios proposed for the origin of the multiple, helium-enriched populations in massive globular clusters are critically compared to the relevant constraining observations. Among accretion of helium-rich material by pre-existing stars, star formation out of ejecta from massive AGB stars or from fast rotating massive stars, and pollution by Population III stars, only the AGB option appears to be viable. Accretion or star formation out of outflowing disks would result in a spread of helium abundances, thus failing to produce the distinct, chemically homogeneous sub-populations such as those in the clusters $ω$ Cen and NGC 2808. Pollution by Population III stars would fail to produce sub-populations selectively enriched in helium, but maintaining the same abundance of heavy elements. Still, it is argued that for the AGB option to work two conditions should be satisfied: i) AGB stars experiencing the hot bottom burning process (i.e., those more massive than $\sim 3 \msun$) should rapidly eject their envelope upon arrival on the AGB, thus experiencing just a few third dredge-up episodes, and ii) clusters with multiple, helium enriched populations should be the remnants of much more massive systems, such as nucleated dwarf galaxies, as indeed widely assumed.

description: In gauge/gravity duality, the bulk double cone geometry has been argued to account for a key feature of the spectral form factor known as the ramp. This feature is deeply associated with quantum chaos in the dual field theory. The connection with the ramp has been demonstrated in detail for two-dimensional theories of bulk gravity, but it appears natural in higher dimensions as well. In a general bulk theory the double cone might thus be expected to dominate the semiclassical bulk path integral for the boundary spectral form factor in the ramp regime. While other known spacetime wormholes have been shown to be unstable to brane nucleation when they dominate over known disconnected (factorizing) solutions, we argue that the double cone is stable to semiclassical brane nucleation at the probe-brane level in a variety of string- and M-theory settings. Possible implications for the AdS/CFT factorization problem are briefly discussed.

A geostatical evaluation of the southern tail zone of Equity Silver Mines, Limited, Houston, B.C.
Creators: name: Giroux, Gary Henri
Publisher: name: University of British Columbia
Year: 2010

description: The Southern Tail zone of Equity Silver Mines, Sam Goosly silver-copper deposit presents an interesting challenge not only for global and local ore reserve estimations, but also for maintaining quality control on sampling and assaying. Silver grades from both stockwork and massive galena-sphalerite lenses vary as much as, 3 orders of magnitude across very short distances. Geostatistical methods have been developed to minimize the effects of erratic mineralization on reserve estimation and quality control. Conditional probability is demonstrated as a global ore reserves estimation method for the Southern Tail zone using exploration diamond drill data. The entire procedure, including declustering, structural analysis and conditioning raw data distributions to block grade distributions is outlined. Results are presented as a grade tonnage curve and compared to estimates calculated by inverse distance. A statistical and graphical approach to evaluating paired data is presented as a method of monitoring the quality of sampling and assaying. Results from the Southern Tail zone indicate a bias in silver analyses between two laboratories, a large random error in the standard tube sampling technique for blasthole cuttings and an inverse relationship between sampling error and sample volume. An idealized calculation based on possible improvement of sampling method indicates that a significant increase in metal recovery could be attained through better sampling. For local block estimation, a variety of kriging techniques have been evaluated and compared with inverse distance and polygonal estimates. Both cross validation and comparison of kriging errors showed that log kriging of selection mining units using partitioned sample data is superior to other methods, although only marginally so in some cases. For a test area of 100 blocks on the 1310 N bench estimated by the various methods, the polygonal method predicted 1.4 million grams of silver more than a log partitioned method. While no conclusions can be drawn as to which method is correct, the necessity of monitering the metal content from specific blocks early in the production life of a mine is stressed.

Mathis - we define a complex structure on several spaces of real-valued elementary functions. This is used to algebraize inhomogeneous linear ordinary differential equations with inhomogenities stemming from these spaces. Thus we deduce an effective method to calculate particular solutions of these ODEs in a purely algebraic way.

The archaeological research is supplemented by interdisciplinary palaeo-environmental and geomorphological studies.
title: Essays in Islamic finance and banking
Creators: name: Al Balooshi, Sara
Publisher: name: University of St Andrews
Year: 2020

description: This thesis comprises three essays on Islamic investment securities (sukuk) and Islamic banking products. Data show that firms in dual financial system economies utilize traditional and Islamic instruments simultaneously to raise funds. Hence, religion is not the sole motive for Islamic transactions. That is attributed to the structure of sukuk, either promoting transparency or obscuring firm information. Chapter II investigates the relationship between firms' opacity and the choice to issue sukuk, given the availability of traditional external sources. We find that as opacity increases, the probability of firms' issuing zero-coupon (ZC) sukuk is the highest followed by conventional bonds and profit-loss sharing (PLS) sukuk. Therefore, opacity has a significant role in choosing between traditional and Islamic instruments, and that issuing zero-coupon sukuk requires more supervision. Chapter III uses a modified pecking order theory to place sukuk in firms' financial hierarchies among debt and equity. We look at the firms' funding choices at two thresholds: exhaustion of internal funds and maximum debt capacity. Firms' choice indicates the level of adverse selection and information asymmetry involved in issuing sukuk. When internal funds are exhausted, firms prefer to issue Profit-loss sharing sukuk over bonds, and fixed income sukuk is placed before equity beyond firms' maximum leverage. Thus, sukuk can widen the external funding spectrum, and the modified pecking order can accommodate sukuk. Chapter IV looks at the investors of such instruments. We investigate the Islamic banks' product mix to verify the claim that Islamic banks are identical to conventional banks due to the concentration of debt-like products. We hand-collected the values of each Islamic banking product otherwise aggregated under "loans". We document that while debt-like products positively affect bank performance, profit-loss sharing products enhance solvency. Contrary to theoretical claims, Islamic banks portfolios are not concentrated. Chapter I introduces Islamic finance and products, while Chapter V concludes.

Dielectric and polarization experiments in high loss dielectrics: a word of caution

description: The recent quest for improved functional materials like high permittivity dielectrics and/or multiferroics has triggered an intense wave of research. Many materials have been checked for their dielectric permittivity or their polarization state. In this report, we call for caution when samples are simultaneously displaying insulating behavior and defect-related conductivity. Many oxides containing mixed valent cations or oxygen vacancies fall in this category. In such cases, most of standard experiments may result in effective high dielectric permittivity which cannot be related to ferroelectric polarization. Here we list few examples of possible discrepancies between measured parameters and their expected microscopic origin.

description: A simple exactly solvable model is proposed for describing the decays $Υ(4S) \rightarrow B^0\bar B^0$ and $Υ(4S) \rightarrow B^+B^-$. Our predictions agree with available experimental data. Using this model, we analyze the Coulomb effects in the spectra of these decays. It is shown that the frequently used assumption of factorization of Coulomb effects is not fulfilled. The Coulomb interaction leads to the difference in the positions and heights of the peaks corresponding to the charged and neutral modes. As a result, the ratio of probability of $Υ(4S)\rightarrow B^+B^-$ decay and $Υ(4S) \rightarrow B^0\bar B^0$ decay is a nontrivial function of energy.

description: On Hokkaido Island, the northernmost island cluster of the Japanese archipelago, humans started to make clay vessels already about 9000 years BC. However, their use of pottery was not related to sedentary lifestyle and crop cultivation only started several millennia later. Hunter-gatherer communities with specialization on coastal seafood were common until historical periods, even until very recent times. The trajectory from use and management of natural resources to food production seems very different from what we know of other world regions. The aim of our research is to find out under which environmental and climate conditions the earliest inhabitants of Northern Japan developed which strategies of resource utilization. Networks of good exchange and ritual monuments receive special attention.

This collection lends new insight into the different phases of construction from pre-Flavian to Maxentian time and therefore enables a better understanding of the Imperial palace’s development. Furthermore, careful examination allows us to reflect on the supply mechanisms as well as repartition of the production centres from whence the bricks used on the Palatine Hill originated.

description: We have compared the optical emission line ratios of type 2 quasars from Zakamska et al. with standard AGN photoionization model predictions, Seyfert 2s, HII galaxies, and narrow line FRII radio galaxies. Moderate to high ionization narrow line radio galaxies and Seyfert 2s are indistinguishable from type 2 quasars based on their optical line ratios. The standard AGN photoionization models, widely discussed for other type 2 AGNs, can reproduce successfully the loci and trends of type 2 quasars in some of the main diagnostic diagrams. These models are not exempt of problems and the discrepancies with the data are the same encountered for other type 2 AGNs. As for these, realistic models must take into account a range of cloud properties, as widely demonstrated in the literature. We also study the possible impact of stellar photoionization.

description: Feature ranking and selection is a widely used approach in various applications of supervised dimensionality reduction in discriminative machine learning. Nevertheless there exists significant evidence on feature ranking and selection algorithms based on any criterion leading to potentially sub-optimal solutions for class separability. In that regard, we introduce emerging information theoretic feature transformation protocols as an end-to-end neural network training approach. We present a dimensionality reduction network (MMINet) training procedure based on the stochastic estimate of the mutual information gradient. The network projects high-dimensional features onto an output feature space where lower dimensional representations of features carry maximum mutual information with their associated class labels. Furthermore, we formulate the training objective to be estimated non-parametrically with no distributional assumptions. We experimentally evaluate our method with applications to high-dimensional biological data sets, and relate it to conventional feature selection algorithms to form a special case of our approach.

State reduction dynamics in a simplified QED model

Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)

description: A simplified model of quantum electrodynamics involving a charged two-state system interacting with an electromagnetic field mode is examined. By extending the Schrodinger equation to include stochastic and nonlinear terms the dynamical process of quantum state reduction can be represented. A specific choice of modified Schrodinger dynamics is shown to result in stable coherent field states. The two-state system undergoes an induced state reduction to a generalised current state due to its interaction with the field mode. Numerical results are presented demonstrating state reduction dynamics for an initial superposition of two current states. An induced reduction time-scale for the two-state system is derived and confirmed by the numerics.

description: The research project in Dumfriesshire aimed to survey two Iron Age and Roman sites and their immediate environs near Lockerbie (Scotland, United Kingdom). With the help of a magnetic survey and soil sampling (coring) in selected areas of the sites a team from the Romano-Germanic Commission investigated the sites of Burnswark (indigenous hillfort and fortlet, Roman siege or training camps) and Ladyward (Roman Fort) to prepare a larger research project, which will deal with the confrontation, cooperation or collaboration of indigenous societies and the Roman occupiers in Scotland between Hadrian’s and Antonine’s Wall in the late first and second century AD from a landscape archaeological perspective.

description: The research results presented here shed new light on various aspects of the Late Mycenaean community of Tiryns between ca. 1250 and 1150 BC. These roughly hundred years were of crucial significance for the site since they brought along the transformation of the palatial center into one of the most important towns of the early post-palatial period in Greece. The report focuses on four sub-projects that are relevant for this period: (1) the study of wallpaintings of the late palace which were uncovered in excavations since the early 20th century, (2) a paleoseismological investigation of whether the site was indeed destroyed around 1200 BC by an earthquake, (3) a physical anthropological and paleopathological study of skeletons of the late palatial and post-palatial periods encountered since the 1960s in the Lower Citadel and (4) the new excavation in the Northwestern Lower Town which tries to understand the unique phenomenon of the seemingly systematic rebuilding of the area to the north of the citadel in the immediate aftermath of the palatial destruction.
Roles of the tensor and pairing correlations on the halo formation in 11Li

description: We study the roles of the tensor and pairing correlations on the halo formation in 11Li with an extended 9Li+n+n model. We first solve the ground state of 9Li in the shell model basis by taking 2p-2h states using the Gaussian functions with variational size parameters to take into account the tensor correlation fully. In 11Li, the tensor and pairing correlations in 9Li are Pauli-blocked by additional two neutrons, which work coherently to make the configurations containing the 0p1/2 state pushed up and close to those containing the 1s1/2 state. Hence, the pairing interaction works efficiently to mix the two configurations by equal amount and develop the halo structure in 11Li. For 10Li, the inversion phenomenon of s- and p-states is reproduced in the same framework. Our model furthermore explains the recently observed Coulomb breakup strength and charge radius for 11Li.

description: At over 6000 square meters (74,1 m × 81,08 m), the Leonidaion is the largest preserved building at Olympia and is the focus of an ongoing building survey, which began as a dissertation project in May 2014. This well-known, important structure to the southwest of the Altis was funded by Leonides of Naxos in about 330 BC. The first German excavations from 1878 until 1881 uncovered its northern portion, and the southern part was excavated from 1954 until 1956 under the overall direction of Emil Kunze. Despite its unique design and its long and eventful history of renovation, the Leonidaion has otherwise remained unstudied. This project will provide the systematic, scientific building survey, which has been lacking.
