description: Type Ia Supernovae (SNe Ia) are widely used as standard candles to probe the Universe. However, how these fierce explosions are produced itself is still a highly debated issue. There are mainly two popular models for SNe Ia, i.e. the double-degenerate scenario and the single-degenerate scenario. The double-degenerate scenario suggests that SNe Ia are produced by the coalescence of two degenerate white dwarfs, while the single-degenerate scenario suggests that the continuous accretion of a single degenerate white dwarf from its normal stellar companion will finally lead to a disastrous explosion when it is over-massive, resulting in an SN Ia. The rapid development of the gravitational wave astronomy sheds new light on the nature of SNe Ia. In this study, we calculate the gravitational wave emissions of double white dwarf coalescences and compare them with the sensitivities of several upcoming detectors. It is found that the gravitational wave emissions from double white dwarf mergers in the locale universe are strong enough to be detected by LISA. We argue that LISA-like gravitational wave detectors sensitive in the frequency range of 0.01 - 0.1 Hz will be a powerful tool to test the double-degenerate model of SNe Ia, and also to probe the Universe.

description: We explore how III-V semiconductor microring resonators can efficiently generate photon pairs and squeezed vacuum states via spontaneous parametric down-conversion by utilizing their built-in quasi phase matching and modal dispersion. We present an analytic expression for the biphoton wave function of photon pairs generated by weak pump pulses, and characterize the squeezed states that result under stronger pumping conditions. Our model includes loss, and captures the statistics of the scattered photons. A detailed sample calculation shows that for low pump powers conversion efficiencies of 10$^{-5}$, corresponding to a rate of $39$ MHz for a pump power of 1 $μ$W, are attainable for rudimentary structures such as a simple microring coupled to a waveguide, in both the continuous wave and pulsed excitation regimes. Our results suggest that high levels of squeezing and pump depletion are attainable, possibly leading to the deterministic generation of non-Gaussian states.

title: Energetics of moulting in phocid seals
Creators: name: Paterson, William David
Publisher: name: University of St Andrews
Year: 2019

description: The moult in phocid seals is a distinct period when behavioural and physiological changes occur. During this key stage in the annual life cycle animals elevate skin temperature to facilitate proliferation of hair follicle cells as they shed and renew their entire pelage. Due to the physiological constraints of raising skin temperature while in the water animals must haul out on land with increasing duration as the moult proceeds. The overall aim of this thesis was to provide insight into the physiology of moulting in phocid seals and to determine the physiological consequences associated with changes in haulout behaviour caused by anthropogenic disturbance. In harbour seals, metabolic rate was higher during the moult compared to when the moult had finished, particularly during the first 40 minutes after hauling out. Subcutaneous temperature increased at a faster rate and reached a higher asymptote when seals were moulting. High skin temperatures were also recorded in moulting southern elephant seals resulting in increased heat flux to the surrounding environment. Heat loss values equated to animals having a metabolic rate of up to 2.3 x Kleiber. Disturbance trials of harbour seals showed that individuals were highly site faithful to haulout locations despite repeated disturbance. The impact of disturbance is therefore not to cause animals to transition to another site but to increase the frequency with which animals enter the water and the duration of time spent at sea. Similar levels of disturbance may have thermoregulatory consequences when seals are in a moulting state. These results demonstrate physiological changes during the moult that incur an increased metabolic demand. Anthropogenic disturbance that causes seals to enter the water at a higher frequency than normal when moulting may incur a cumulative energetic cost. Mitigation to protect seals at haulout sites during the moult are supported by these findings.
An explanation for the muon and electron $g-2$ anomalies and dark matter

description: We propose simple models with a flavor-dependent global $U(1)_\ell$ and a discrete $\mathbb{Z}_2$ symmetries to explain the anomalies in the measured anomalous magnetic dipole moments of muon and electron, $(g-2)_{μ,e}$, while simultaneously accommodating a dark matter candidate. These new symmetries are introduced not only to avoid the dangerous lepton flavor-violating decays of charged leptons, but also to ensure the stability of the dark matter. Our models can realize the opposite-sign contributions to the muon and electron $g-2$ via one-loop diagrams involving new vector-like leptons. Under the vacuum stability and perturbative unitarity bounds as well as the constraints from the dark matter direct searches and related LHC data, we find suitable parameter space to simultaneously explain $(g-2)_{μ,e}$ and the relic density. In this parameter space, the coupling of the Higgs boson with muons can be enhanced by up to $\sim 38\%$ from its Standard Model value, which can be tested in future collider experiments.

description: We present a systematic study of the low mass X-ray binary (LMXB) populations of 6 elliptical galaxies. We utilize Chandra archival data to identify 665 X-ray point sources and HST archival data supplemented by ground observations to identify 6173 GCs. We associate 209 LMXBs with red GC (RGC) and 76 LMXBs with blue GCs (BGC), while we find no optical GC counterpart for 258 LMXBs. This is the largest GC-LMXB sample studied so far. We confirm previous reports suggesting that the fraction of GCs associated with LMXBs is 3 times larger in RGCs than in BGCs, indicating that metallicity is a primary factor in the GC-LMXB formation. While as already known, the brighter (and bigger) GCs have a higher probability to host LMXBs, we find that this optical luminosity (or mass) dependency is stronger in RGCs than in BGCs. We also find that GCs located near the galaxy center have a higher probability to harbor LMXBs compared to those in the outskirts. The radial distributions of GC-LMXBs (for both RGC and BGC) are steeper than those of the whole optical GC sample, but consistent with those of the optical halo light, suggesting that there must be another parameter (in addition to metallicity) governing LMXB formation in GCs. This second parameter must depend on the galacto-centric distance. We find no statistically significant difference in the X-ray properties among RGC-LMXBs, BGC-LMXBs and field-LMXBs. The similarity of the X-ray spectra of BGC-LMXBs and RGC-LMXBs is inconsistent with the irradiation-induced stellar wind model prediction. The similarity of the X-ray luminosity functions (XLFs) of GC-LMXBs and field-LMXBs indicates that there is no significant difference in the fraction of BH binaries present in these two populations, in contrast to Galactic LMXBs where BH binaries are not found in GCs.

description: We investigate the thermodynamics and signatures of a polariton condensate over a range of densities, using a model of microcavity polaritons with internal structure. We determine a phase diagram for this system including fluctuation corrections to the mean-field theory. At low densities the condensation temperature, T_c, behaves like that for point bosons. At higher densities, when T_c approaches the Rabi splitting, T_c deviates from the form for point bosons, and instead approaches the result of a BCS-like mean-field theory. This crossover occurs at densities much less than the Mott density. We show that current experiments are in a density range where the phase boundary is described by the BCS-like mean-field boundary. We investigate the influence of inhomogeneous broadening and detuning of excitons on the phase diagram.

Apart from that it is also an ideal laboratory for precision measurements in the top quark sector. Both applications require a solid theoretical prediction, which can be achieved only through a full next-to-leading order (NLO) calculation. In this work we describe the NLO computation of the subprocess gg -> t tbar g.

description: Outlines major social and ecological issues involved in the coevolution of social and ecological systems by initially reviewing relevant aspects of the recent literature relating to economic development and their implications for agricultural development. Coevolutionary qualitative-type models are presented. There has been a failure amongst advocates of structural adjustment policies (involving the extension of markets and economic globalisation) to take account of coevolutionary principles and allow for historical differences in the evolution of communities and their varied circumstances. This lack of sensitivity has had unfortunate social and ecological consequences for some communities eg The Russian Federation and subsistence agriculturalists in some less developed countries. The evolution of globalized market systems involving industrial/commercial agriculture (largely dependent on inputs external to the farm) under the 'patronage' of oligopolistic suppliers is seen to increasingly threaten the balance between social and ecological systems and as undermining the sustainability of both. Capitalistic processes of technological change eg advances in biotechnology, play a major role in this evolution

description: Recently, many new excited states of heavy mesons, especially the radially excited states, are discovered. The study of the production processes of these states from the ground b-flavored mesons is of interest. In this paper, we use the improved Bethe-Salpeter method to study the semi-leptonic and non-leptonic decays of $B$, $B_s$, and $B_c$ mesons, where the final states are focused on the radial excited $2S$ and $3S$ states. We find that many channels have branching ratios up to $10^{-4}$, which are within the detection accuracy of current experiments.

description: Considerable public funding is provided for research and development intended to improve the management and use of shared natural resources, such as water. In Australia the Land and Water Research and Development Corporation (LWRRDC) and Environment Australia are significant providers of such funds. These providers tend to judge the value of R & D projects supported by them on the basis of whether or not significant technology transfer and adoption takes place. Researchers involved in these projects and expected to be the prime movers of such transfer. However, it seems that research funders have been guided by over simplified models of processes of technology transfer and by false analogies with the transfer of industrial technology. There has been a failure to recognise that much of the new technology developed to improve the management of shared resources, such as water, affects the supply of social or collective commodities, a factor which materially alters the technology transfer process. Here processes of transferring publicly-funded intellectual knowledge are discussed and modelled, dynamic patterns of adoption of new technology are considered along with factors influencing adoption rates and barriers to adoption, particularly when the supply of social or collective commodities such as water, are involved. Some points from the analysis are illustrated by observations from a sample of LWRRDC-supported research projects.

description: Symbiotic vortex-bright soliton structures with non-trivial topological charge in one component are found to be robust in immiscibel two-component superfluids, due to the effective potential created by a stable vortex in the other component. We explore the properties of symbiotic vortex-bright soliton in strongly coupled binary superfluids by holography, which naturally incorporates finite temperature effect and dissipation. We show the dependence of the configuration on various parameters, including the winding number, temperature and inter-component coupling. We then study the (in)stability of symbiotic vortex-bright soliton by both the linear approach via quasi-normal modes and the full non-linear numerical simulation. Rich dynamics are found for the splitting patterns and dynamical transitions. Moreover, for giant symbiotic vortex-bright soliton structures with large winding numbers, the vortex splitting instability might be rooted in the Kelvin-Helmholtz instability. We also show that the second component in the vortex core could act as a stabilizer so as to suppress or even prevent vortex splitting instability. Such stabilization mechanism opens possibility for vortices with smaller winding number to merge into vortices with larger winding number, which is confirmed for the first time in our simulation.

description: Modern new biotechnology has the potential to provide major economic and other benefits, but at the same time it poses potential hazards for human health, the environment, the ‘natural’ biological order and can have adverse socio-economic consequences. The application of such technology frequently violates traditional ethical, moral and religious values. This paper after outlining possible benefits of modern new biotechnologies, discusses the type of biosafety risks which they pose, their possible adverse consequences for the sustainability of biodiversity and agriculture and their potential impacts on socioeconomic welfare and traditional cultures. Particular concern is expressed about the possible consequences of such technologies for developing countries and the practice in some developed countries of issuing patents conferring very broad rights over the use of genetically engineered material. Because these rights are so broad in some cases they have the potential to establish powerful multinational monopolies in the hands of private companies. Global debate about these issues suggest that more emphasis should be given globally to the socio-economic consequences of such technology than in the past. The need for this is highlighted by the North-South divide. Developing countries lag considerably in this new technological field, are placed in a dependant position and have weak institutional structures to control the application of such technology

description: Conservation of biodiversity can generate considerable indirect economic value and this is being increasingly recognized in China. For a forest ecosystem type of a nature reserve, the most important of its values are its ecological functions which provide human beings and other living things with beneficial environmental services. These services include water conservancy, soil protection, CO2 fixation and O2 release, nutrient cycling, pollutant decomposition, and disease and pest control. Based on a case study in Changbaishan Mountain Biosphere Reserve in Northeast China, this paper provides a monetary valuation of these services by using, opportunity cost and alternative cost methods. Using such an approach, this reserve is valued at 510.11 million yuan (USD61.68 mill.) per year, 10 times higher than the opportunity cost (51.78 mill. yuan/ha.a) for regular timber production. While China has heeded UNEP's call for economic evaluation of ecological functions, the assessment techniques used need to be improved in China and in the West for reasons mentioned.

description: Hydrogen cyanide (HCN) is a critical reactive source of nitrogen for building key biomolecules relevant for the origin of life. Still, many HCN reactions remain uncharacterized by experiments and theory, and the complete picture of HCN production in planetary atmospheres is not fully understood. To improve this situation, we develop a novel technique making use of computational quantum chemistry, experimental data, and atmospheric numerical simulations. First, we use quantum chemistry simulations to explore the entire field of possible reactions for a list of primary species in N2-, CH4-, and H2-dominated atmospheres. In this process, we discover 33 new reactions with no previously known rate coefficients. From here, we develop a consistent reduced atmospheric hybrid chemical network (CRAHCN) containing experimental values when available, and our calculated rate coefficients otherwise. Next, we couple CRAHCN to a 1D chemical kinetic model (ChemKM) to compute the HCN abundance as a function of atmospheric depth on Titan. Our simulated atmospheric HCN profile agrees very well with the Cassini observations. CRAHCN contains 104 reactions however nearly all of the simulated atmospheric HCN profile can be obtained using a scaled down network of only 19 dominant reactions. From here, we form a complete picture of HCN chemistry in Titan's atmosphere, from the dissociation of the main atmospheric species, down to the direct production of HCN along 4 major channels. One of these channels was first discovered and characterized in Pearce et al. (2019) and this work.

description: Important features of the safe minimum standard (SMS) rule as outlined by Ciriacy-Wantrup are ignored in the recent literature, e.g., the critical zone, institutional and normative dimensions, and the relationship between economic and biological irreversibility. Also, seeing SMS as an adjunct to social cost-benefit analysis is inconsistent with the original concept. Since SMS is usually applied to collective commodities, consideration of normative and institutional factors is inescapable. Hence, 'unacceptably large' social costs cannot be made operational by traditional social cost-benefit analysis. Close relatives of SMS such as discontinuous objective functions, the precautionary principle and reversal of proof are also discussed, as well as the determination of SMS by social discourse

description: The properties of antiferromagnetic materials with violated space-time parity are considered. Particular attention is given to the bismuth ferrite BiFeO3 ferroelectric magnet. This material is distinguished from other antiferromagnets in that the inversion center is absent in its crystal and magnetic structures. This circumstance gives rise to the diversified and unusual properties, namely, to the appearance of a spatially modulated spin structure and to the unique possibility of the linear magnetoelectric effect coexisting with a weak ferromagnetic moment. The magnetic-induced phase transitions accompanied by the suppression of the modulated spin structure and appearance of a number of new and unusual effects are considered. These are the linear magnetoelectric effect and the appearance of a toroidal moment and a weak ferromagnetic moment of the magnetoelectric nature.

Ultrafast coherent studies of excitons and excitonic complexes in doped and undoped GaAs quantum wells

Year: 2009

description: This thesis reports a systematic study of near-band edge linear and nonlinear optical properties of doped and undoped semiconductor multiple quantum well samples, aimed at quantifying and separating the numerous contributions to the overall material response from photon excitation. Information obtained from both linear absorption and nonlinear, degenerate four-wave-mixing experiments is compared with elaborate numerical simulations. Accurate measures of 1S-2S binding energies and dephasing rates as a function of temperature from 5 to 40K is established. The biexciton binding energy and dephasing. rate over the temperature range 5 to 40 K is measured and, by comparison with theories reported in the literature, it is found that localization effects have a significant influence on the biexciton binding energy in 5 nm quantum wells. The first systematic attempt to quantitatively account for the continuum contribution to nonlinear response by fitting a series of spectra obtained at various input laser pulse detunings was conducted. Unique evidence for coherent beating between multi-exciton/free electron complexes in lightly doped material was also found.

We identify a mapping that reveals a remarkable property, namely, fermionic and bosonic gases have the same many-body density of states, up to a shift corresponding to ground state energy. Additionally, we show that there is a regime, comprising the validity range of the Bethe approximation, where the many-body density of states becomes independent of the number of particles.

description: The public R&D system represents an important part of the framework conditions for carrying out innovation activities and creating commercially applicable knowledge (Drejer and Jørgensen, 2004). It is an important source of information for companies, particularly those that are developing new products (Tijssen, 2004). However, Rubenstein (2003) stated that there has been a perception that public research capacity and results were not being optimally used and thus that potential economic benefits were not entirely realised. It is also suggested that research conducted in the public sector is not efficiently or successfully transferred to industry (Markman et al, 1999) and that it is necessary to understand and improve the means of technology transfer for society to reap the benefits of public science (Geuna and Nesta, 2003). Thus, there is a growing interest, and indeed pressure, among policymakers and academics to ensure informed spending of taxpayers’ money, that useful and relevant research is conducted that represents good “value for money” and that wealth is generated from publicly-funded research (Carr, 1992; Lyall et al., 2004; Mustar et al., 2006). To achieve this requires, amongst other things, the establishment of scientific and technical human capital which is the sum of researchers’ professional network ties and their technical skills and resources (Bozeman and Coreley, 2004). This paper examines the interactions engaged in by researchers from Irish public science providers (public research centres and higher education institutions), with a particular focus on researchers- industry interactions, as well as their skills and resources. To provide context, it firstly briefly outlines the actors involved in conducting publicly funded R&D in Ireland. It then describes the methodology and presents the results of a national survey of publicly funded food researchers focusing on the extent and nature of researcher interactions with other researchers and with industry, the barriers to and motivations for researcher-industry interaction and researcher skills regarding technology transfer. It concludes with a discussion and some policy recommendations.

description: The recent explosion in the availability of echosounder data from diverse ocean platforms has created unprecedented opportunities to observe the marine ecosystems at broad scales. However, the critical lack of methods capable of automatically discovering and summarizing prominent spatio-temporal echogram structures has limited the effective and wider use of these rich datasets. To address this challenge, we develop a data-driven methodology based on matrix decomposition that builds compact representation of long-term echosounder time series using intrinsic features in the data. In a two-stage approach, we first remove noisy outliers from the data by Principal Component Pursuit, then employ a temporally smooth Nonnegative Matrix Factorization to automatically discover a small number of distinct daily echogram patterns, whose time-varying linear combination (activation) reconstructs the dominant echogram structures. This low-rank representation provides biological information that is more tractable and interpretable than the original data, and is suitable for visualization and systematic analysis with other ocean variables. Unlike existing methods that rely on fixed, handcrafted rules, our unsupervised machine learning approach is well-suited for extracting information from data collected from unfamiliar or rapidly changing ecosystems. This work forms the basis for constructing robust time series analytics for large-scale, acoustics-based biological observation in the ocean.

description: result, enterprises in the agribusiness sector are increasingly exposed to the public eye (Jansen/ Vellema: 2004). The perception of consumers and other stakeholders - which are according to Freeman “any group or individual who can affect, or is affected by, the achievement of the organization’s objectives” - is of growing criticism and risk-consciousness and manifests itself in changed attitudes towards food production (Jäckel/Spiller: 2006; Haddock: 2005). The use of GMO in agriculture, e.g., is regarded to be morally reprehensible (Becker: 1999). The BSE-crisis and other food scares led to growing consumer uncertainty and resulted in decreased meat consumption and in the increasing percentage of outspoken vegetarians and low-meat consumers (von Alvensleben: 1997; Staack: 2005). Moreover, the influence capacity of stakeholders is growing (Gerlach: 2006). As a result these factors have reduced the legitimacy of traditional (e.g., animal production) as well as new production technologies (e.g. bioenergy) in the agribusiness. In the long term the success of enterprises in the agribusiness can be affected by legitimacy losses. Against this background, legitimacy is regarded as a resource that guarantees the long-term survival of an enterprise (Palazzo/Scherer: 2006). Primarily the market based view in general management literature and the macro-institutional approach in neo sociological-institutionalism are employed to understand business operations embedded in societal structures. In this context legitimacy means the conformation of an organization with social norms, values and expectations (Oliver: 1996).

description: We analyse the renormalisation group flow for D-branes in WZW models from the point of view of the boundary states. To this end we consider loop operators that perturb the boundary states away from their ultraviolet fixed points, and show how to regularise and renormalise them consistently with the global symmetries of the problem. We pay particular attention to the chiral operators that only depend on left-moving currents, and which are attractors of the renormalisation group flow. We check (to lowest non-trivial order in the coupling constant) that at their stable infrared fixed points these operators measure quantum monodromies, in agreement with previous semiclassical studies. Our results help clarify the general relationship between boundary transfer matrices and defect lines, which parallels the relation between (non-commutative) fields on (a stack of) D-branes and their push-forwards to the target-space bulk.

description: Continuous quantum measurement and feedback induce energy exchange between a dissipative qubit and a monitor even in the steady state, as a measurement backaction. Using the Lindblad equation, we identified the maximum and minimum values of the steady-state energy flow as the measurement and feedback states vary, and we demonstrate the qubit cooling induced by these processes. Turning our attention to quantum trajectories under continuous measurement and feedback, we observe that the energy flow fluctuates around the steady-state values. We reveal that the fluctuations are strongly influenced by the measurement backaction, distinguishing them from the standard Poisson noise typically observed in electronic circuits. Our results offer potential application in the development of quantum refrigerators controlled by continuous measurement and feedback, and provide deep insight into quantum thermodynamics from the perspective of fluctuation.

Critical commentary from Tuning In to Characters: Translating Mónica Ojeda's La desfiguración Silva

description: Developments in narrative theory have seen a burgeoning of scholarly interest in the mimetic thickness of characters in fiction. Previously, structuralists were suspicious of the emotional involvement that comes with viewing characters as possible people, which may explain in part why character analysis in the practice of literary translation has been studied so seldom. My thesis seeks to address this gap, using Marie-Laurie Ryan’s ‘world model’ of characters. It seeks to argue that character analysis can be a powerful tool for translators of literary fiction. It can assist them to shape their translation strategy and define their translation choices. I argue as much through an approach that interweaves theoria and praxis. I devote half my thesis to a translation of Mónica Ojeda’s archival novel, La desfiguración Silva. In carrying out this translation, I mobilise character analysis in several ways: to formulate my preliminary translation strategy; to render voice; and to nuance other, genre-based decisions. In the process, I develop what I refer to throughout my critical commentary as an ethics of disfigurement, which recalls not only the source text through which this ethics was developed, but also Antoine Berman’s ‘textual deformation’. By way of this allusion, I cast disfigurement in a contrary posture, spotlighting the gains that works stand to accrue when they are recreated by other people in other cultures. My translation is full of deformations; it is also, if it has succeeded in what I set out to do, respectful of the work’s ‘shapeless polylogic’. Engaging with Gayatri Chakravorty Spivak’s translations and theories helped me envision this apparently paradoxical state as one I wished to strive for.

description: Economic and environmental challenges in the global economy raise significant issues that require public policy and private sector attention over the next decade. Price volatility, invasive species, sustainable biofuels production, and climate change all affect our agricultural and resource base and its future. Agricultural and resource economists must provide analyses of public policy and private sector strategies based on innovative research that integrates insights across disciplinary boundaries. Proactive communication of the results to decision makers can make a difference in how these important societal issues are addressed and help to shape the future.

An Overview of the U.S. Agricultural Economy and the 2008 Farm Bill

subject: farm bill
subject: farm programs
subject: ACRE
subject: permanent disaster assistance
subject: regulatory process

description: The 2008 farm bill involved 16 months of debate. The end product is similar to the 2002 farm bill in the crops arena, continuing counter-cyclical payments, direct payments, and marketing assistance loans. In addition, however, the 2008 bill adds a new, optional counter-cyclical revenue program (Average Crop Revenue Election, or ACRE), authorizes a new permanent disaster program, and contains various other changes. The new ACRE program provides an entirely new set of dimensions for producers to consider in deciding whether to opt into the program, including the multi-year trade-off between the loss of potential “traditional” payments and the revenue protection provided by ACRE, as well as the producer’s own expectations about yield and price trends and variability. The payment calculation associated with the new permanent disaster program appears at first glance to be relatively simple, although the whole-farm nature of the program and the number of variables makes it quite complex.
Torres funerarias chullpa en el valle del río Lauca: un primer análisis arqueoastronómico

description: In this work we employ the methods of archaeoastronomy to analyze the orientation, possibly astronomical, of numerous groups of chullpa funerary towers, mainly from the 12th to 16th centuries, located in the Lauca River valley of the central Bolivian highlands. Despite their great historical relevance, both regarding the beliefs and funerary customs of the local populations and the characteristics of the landscape in the highlands, little is known about the relationship of these mortuary monuments with the sky. Several authors, from chroniclers of the colonial era to more modern explorers, indicate that the tomb towers of these regions are oriented in such a way that important parts of their structure (in general, the entrances of the chullpas) point towards the sunrise on the eastern horizon, in order to be imbued with the first rays of the Sun. However, the sunrise changes its location noticeably at different times of the year. Given the lack of written information or other forms of original documentation, in order to affirm the use of a systematic orientation, it is necessary to measure a statistically significant number of monuments. We present here the results of the analysis of the precise spatial orientation of the entrances of 80 towers measured in situ during field work in the Lauca River valley. We find that, except for a few, all the buildings have the openings' axes oriented towards the east and within the solar range, between the extreme azimuths of the annual movement of the Sun as it crosses the local horizon, with a notable concentration of entrances that point slightly towards the north of due east. Our work is the first systematic study of the orientations of the chullpa towers of the Lauca River and can provide crucial information to understand the evolution and scope of the chullpa phenomenon in the Bolivian highlands and in the entire surrounding region.
