Children’s Television as a Medium for Social Orientation? – An Approach in the Perspective of Children’s Use of Television
Creators: name: Raabe, Claudia
Publisher: name: JSSE - Journal of Social Science Education
Year: 2009

description: The development of individualism, distinction and pluralism has not simply slipped by the every-day life of children and youth. Today they are moreover understood as humans, who take an active role in their social life. On the threshold from being a child to becoming an adolescent, children find themselves in a state of radical change, during this process they look out for possibilities of orientation. Accordingly questions of orientation are no longer mainly/principally asked within a personal environment, but increasingly outwards; for example towards the media. Television is still today the main form of media and presents an attractive source of orientation from which the youth today summon up their symbolic materials for their structuring of life. Adults to whom the children relate most closely and educationalists have their own opinion of what is important regarding the social orientation of the children. However which subjects of social orientation interest today’s youth? This question follows the existing work related to the background of the living situation. Which programmes are they viewing and which subjects of social orientation are in their favourites?

title: Nest‐Site Selection, Success, and Response to Predators by Cinnamon Teal and Other Ground‐Nesting Ducks in the Wetlands of Great Salt Lake, Utah
Creators: name: Bell, Mark E.
Publisher: name: Utah State University
Year: 2022

description: The wetlands of Great Salt Lake once supported hundreds of thousands of nesting ducks each year. In recent years, the number of nesting ducks in the same area was a fraction of those historic numbers. While many species of ducks do not rely on these wetlands for primary nesting habitat, cinnamon teal (Spatula cyanoptera) do. Great Salt Lake and its associated wetlands are in the heart of the cinnamon teal breeding range, and once supported half of the continental population.
These wetlands are unique from other wetlands where waterfowl nest because they are artificially created using dams to hold water in large ponds. The vegetation on the dams provides most of the upland nesting habitat in wet springs, as the impoundments fill with water. Nest predators, who depredate duck nests, easily search these narrow trips of vegetation along the sides and tops of the dam.
To be successful at nesting, a duck can hide its nest from predators by selecting a nest site situated in tall and thick vegetation, concealing it from the view of avian predators flying overhead and mammalian predators viewing the nest from the side or at ground level. A duck can also select a nest site concealed from predators that use their sense of smell (olfaction) rather than sight to locate nests. Olfactory concealment comes in the form of vegetation with a rough surface that creates turbulence and breaks up the odor plumes emitted from a duck sitting on its nest making the odor plume difficult to find and follow.
Predators find and destroy nests regardless of weather conditions throughout the spring and early summer. Most predator visits to nests occurred during the periods before and after the new moon, when little illumination from the moon is present. When a predator chases a hen off its nest, there is only a 21% chance the hen will return to the nest, a 90% chance that it will incubate the nest, and only a 5% chance that the nest will go on to successfully hatch an egg.

description: A biexciton in a semiconductor quantum dot is a source of polarization-entangled photons with high potential for implementation in scalable systems. Several approaches for non-resonant, resonant and quasi-resonant biexciton preparation exist, but all have their own disadvantages, for instance low fidelity, timing jitter, incoherence or sensitivity to experimental parameters. We demonstrate a coherent and robust technique to generate a biexciton in an InGaAs quantum dot with a fidelity close to one. The main concept is the application of rapid adiabatic passage to the ground state-exciton-biexciton system. We reinforce our experimental results with simulations which include a microscopic coupling to phonons.

title: Bedrock Geology Map of the Naomi Peak 7.5' Quadangle, Cache County, Utah and Novel Age Constraints on its Cambrian Strata
Creators: name: Cothren, Hannah R.
Publisher: name: Utah State University
Year: 2022

description: Geologists use various “rock-clocks” in order to interpret the timing and tempo of events in Earth’s history. These include global geochemical events in the oceans (chemostratigraphy), the evolution of certain fossil species (trilobite biostratigraphy), and the radiogenic decay of uranium to lead in certain mineral such as zircon (U-Pb geochronology). Integrating these methods in the stratigraphic record in one location can provide a well-constrained timeline for a select part of the Geologic, or Deep Time, record. This technique is especially important in the Cambrian Period (538.8 to 486.9 million years; Ma), which sets the stage for life today with the rise of animals including familiar groups like arthropods.
The Naomi Peak 7.5’ Quadrangle, situated in the Bear River Range, Northern Utah boasts a largely unstudied yet well-preserved and exposed package of sedimentary rocks, with an unusually thick succession of Cambrian strata. We present an updated bedrock geology map of the Naomi Peak Quadrangle, which provides greater detail regarding the character of the sedimentary succession of the rocks in the map area and reveals small, previously unmapped faults.
We use these strata as a living laboratory to test the integration and calibration of traditional rock-clocks and have refined the biostratigraphy of several map units. We build upon previous work in the area by integrating trilobite biostratratigraphy and chemostratigraphy of a prominent oceanic geochemical event called the Steptoean Positive Isotopic Carbon Excursion (SPICE), which provides the first useful age constraint ≤494.4 ± 0.5 Ma. This requires boundaries of the late Cambrian Time Scale to become younger by several millions of years. Dating the SPICE and associated trilobite biozones is key to understanding patterns in evolution and environmental changes due to variations in the ancient carbon cycle, which will be important to understanding the effects of a rapidly changing carbon cycle in the modern.
title: Immunological Tradeoffs and the Impacts of Urbanization on the Reproductive Ecology and Physiology of the Side-Blotched Lizard (Uta stansburiana)
Creators: name: Virgin, Emily E.
Publisher: name: Utah State University
Year: 2022

description: Investing resources into reproduction can limit energy available to other competing demands, such as fighting off an infection; yet, both processes are necessary for organisms to survive and pass on their genes to the next generation. These strategies often follow patterns associated with lifespan, such that shorter-lived animals are more likely to invest more resources into reproduction over survival, and vice versa in long-lived animals. However, environmental change caused by urbanization can disrupt these relationships, and the within- and transgenerational costs of urbanization on females and offspring are unknown. I address these uncertainties in three research chapters to better understand the effects of urbanization on reproductive investment in female Side-blotched Lizards (Uta stansburiana), a small and abundant species of reptile found throughout the western United States. In my second chapter, I examine general variation in female immunity and stress and how it relates to egg number, egg mass, and egg yolk immunity and stress. I found oxidative stress and immunity vary in females depending on how many eggs they produced, and that larger eggs had lower yolk stress levels. I built upon this by examining how metabolism differs across the reproductive cycle and tested whether simulating an infection in females affected immunity, stress, and metabolism. Metabolism was higher at the onset of reproduction and decreased until ovulation, and females differentially responded to infection depending on their stage in the reproductive cycle, which may suggest limited resources underly these findings. In my final chapter, I investigated the impacts of urbanization on female and egg yolk physiology and tested whether simulating infection altered female investment into egg yolk. I found immunity and stress in females and eggs were only apparent in rural females with ectoparasites, but not in urban females and eggs. Fertilization rates were lower in urban populations, which also influenced egg yolk physiology. Differential physiological investment can drastically alter offspring traits; therefore, it is imperative to develop a better understanding of the transgenerational costs of inhabiting an urban environment.
Generating enhanced parity-violating gravitational waves during inflation with violation of the null energy condition

description: A violation of the null energy condition (NEC) during inflation in a single-field inflation model will naturally enhance the amplitude of the parity violation effect (defined by $Δχ$) of inflationary primordial gravitational waves (GWs), provided the inflaton is non-minimally coupled to a gravitational Chern-Simons term. After going through the NEC-violating phase, the Universe enters subsequent slow-roll inflation with a higher energy scale (i.e., a greater Hubble parameter $H$), which results in an enhanced nearly scale-invariant power spectrum (i.e., $P_{\rm T}$) of inflationary primordial GWs in the high-frequency band, while $P_{\rm T}$ remains consistent with observations in the frequency band of the cosmic microwave background. Therefore, the violation of NEC during inflation will amplify the observability (i.e., $P_{\rm T}\cdotΔχ$) of the parity violation effect on small scales. Intriguingly, our model has particular oscillatory features on $Δχ$ that may not be mimicked by others.

description: A study is made of an integral identity of Helffer and Sj{ö}strand, which for some class of probability measures yields a formula for the covariance of two functions (of a stochastic variable). In comparison with the Brascamp--Lieb inequality, this formula is a more flexible and in some contexts stronger means for the analysis of correlation asymptotics in statistical mechanics. Using a fine version of the Closed Range Theorem, the identity's validity is shown to be equivalent to some explicitly given spectral properties of Witten-Laplacians on Euclidean space, and the formula is moreover deduced from the obtained abstract expression for the range projection. As a corollary, a generalised version of Brascamp--Lieb's inequality is obtained. For a certain class of measures occurring in statistical mechanics, explicit criteria for the means are found from the Persson--Agmon formula, from compactness of embeddings and from the Weyl calculus of pseudo-differential operators, which give results for closed range, strict positivity, essential self-adjointness and domain characterisations.

title: Insecticide Susceptibility and Resistance Detection in Phlebotomus argentipes Sandflies (Diptera: Psychodidae: Phlebotominae)

description: Leishmaniasis is an understudied disease found predominantly in high heat and humidity areas. The disease is transmitted by sandflies which are blood-feeding, biting insects. There is currently no known vaccine for any form of leishmaniasis and treatment imposes a significant economic impact on already poor and marginalized populations, as well as severe, lingering side effects for afflicted individuals. Annually, there are millions of people around the world afflicted with a form of Leishmaniasis that is transmitted by species of sandflies. The primary sandfly population control method for over half a century has been indoor residual spraying using insecticides. The selective pressure from utilizing insecticides over such a long period has resulted in selection for resistance which requires an assay to monitor and identify these populations.
The goal of this thesis is to determine and assess insecticide susceptibility and resistance of the sandfly species, Phelebotomus argentipes. Research started by understanding the response of sandflies to particular insecticides of interest. This was completed by assessing levels of susceptibility of the P. argentipes colony to three insecticides which have been used extensively in India throughout the years. Susceptibility curves were developed to determine lethal concentration (LC) of insecticides capable of reducing populations by 50%, 75%, and 90%.
An amplification assay (Polymerase Chain Reaction) was optimized to specifically amplify genetic regions associated with insecticide resistance for P. argentipes sandflies. Whereas, another amplification assay (Loop-mediated Isothermal Amplification) was developed as an effective and rapid procedure for integrated pest management (IPM) professionals to assess the degree of insecticide susceptibility in field collected populations of P. argentipes sandflies. This rapid detection of field collected samples could allow IPM professionals to determine the degree of susceptibility of sandfly populations collected from afflicted areas. Thus, allowing the disease vector to be controlled in a more timely and effective manner.

description: Building management systems tout numerous benefits, such as energy efficiency and occupant comfort but rely on vast amounts of data from various sensors. Advancements in machine learning algorithms make it possible to extract personal information about occupants and their activities beyond the intended design of a non-intrusive sensor. However, occupants are not informed of data collection and possess different privacy preferences and thresholds for privacy loss. While privacy perceptions and preferences are most understood in smart homes, limited studies have evaluated these factors in smart office buildings, where there are more users and different privacy risks. To better understand occupants' perceptions and privacy preferences, we conducted twenty-four semi-structured interviews between April 2022 and May 2022 on occupants of a smart office building. We found that data modality features and personal features contribute to people's privacy preferences. The features of the collected modality define data modality features -- spatial, security, and temporal context. In contrast, personal features consist of one's awareness of data modality features and data inferences, definitions of privacy and security, and the available rewards and utility. Our proposed model of people's privacy preferences in smart office buildings helps design more effective measures to improve people's privacy.

description: The application of Stochastic Differential Equations (SDEs) to the analysis of temporal data has attracted increasing attention, due to their ability to describe complex dynamics with physically interpretable equations. In this paper, we introduce a non-parametric method for estimating the drift and diffusion terms of SDEs from a densely observed discrete time series. The use of Gaussian processes as priors permits working directly in a function-space view and thus the inference takes place directly in this space. To cope with the computational complexity that requires the use of Gaussian processes, a sparse Gaussian process approximation is provided. This approximation permits the efficient computation of predictions for the drift and diffusion terms by using a distribution over a small subset of pseudo-samples. The proposed method has been validated using both simulated data and real data from economy and paleoclimatology. The application of the method to real data demonstrates its ability to capture the behaviour of complex systems.

In particular, we compute the so-called resolved contributions and explore the numerical impact on observables. In these contributions the virtual photon couples to light partons instead of connecting directly to the effective weak-interaction vertex. They represent an irreducible uncertainty in the inclusive $\bar B \to X_s \ell^+ \ell^-$ decay which cannot be removed by relaxing the experimentally necessary cuts in the hadronic mass spectrum.

description: In the present article, we discover a new well-behaved charged anisotropic solution of Einstein-Maxwell's field equations. We ansatz the metric potential $g_{00}$ of the form given by Maurya el al. (arXiv:1607.05582v1) with $n=2$. In their article it is mentioned that for $n=2$ the solution is not well-behaved for neutral configuration as the speed of sound is non-decreasing radially outward. However, the solution can represent a physically possible configuration with the inclusion of some net electric charged i.e. the solution can become a well-behaved solution with decreasing sound speed radially outward for a charged configuration. Due to the inclusion of electric charged the solution leads to a very stiff equation of state (EoS) with the velocity of sound at the center $v_{r0}^2=0.819, ~v_{t0}^2=0.923$ and the compactness parameter $u=0.823$ is closed to the Buchdahl limit 0.889. This stiff EoS support a compact star configuration of mass $5.418M_\odot$ and radius of $10.1 km$.

description: The effect of baryons on the matter power spectrum is likely to have an observable effect for future galaxy surveys, like Euclid or LSST. As a first step towards a fully predictive theory, we investigate the effect of non-radiative hydrodynamics on the structure of galaxy groups sized halos, which contribute the most to the weak lensing power spectrum. We perform high resolution (more than one million particles per halo and one kilo-parsec resolution) non-radiative hydrodynamical zoom-in simulations of a sample of 16 halos, comparing the profiles to popular analytical models. We find that the total mass profile is well fitted by a Navarro, Frenk & White model, with parameters slightly modified from the dark matter only simulation. We also find that the Komatsu & Seljak hydrostatic solution provides a good fit to the gas profiles, with however significant deviations, arising from strong turbulent mixing in the core and from non-thermal, turbulent pressure support in the outskirts. The turbulent energy follows a shallow, rising linear profile with radius, and correlates with the halo formation time. Using only three main structural halo parameters as variables (total mass, concentration parameter and central gas density), we can predict with an accuracy better than 20% the individual gas density and temperature profiles. For the average total mass profile, which is relevant for power spectrum calculations, we even reach an accuracy of 1%. The robustness of these predictions has been tested against resolution effects, different types of initial conditions and hydrodynamical schemes.

description: Inequality indices are quantitative scores that gauge the divergence of wealth distributions in human societies from the "ground state" of pure communism. While inequality indices were devised for socioeconomic applications, they are effectively applicable in the context of general non-negative size distributions such as count, length, area, volume, mass, energy, and duration. Inequality indices are commonly based on the notion of Lorenz curves, which implicitly assume the existence of finite means. Consequently, Lorenz-based inequality indices are excluded from the realm of infinite-mean size distributions. In this paper we present an inequality index that is based on an altogether alternative Langevin approach. The Langevin-based inequality index is introduced, explored, and applied to a wide range of non-negative size distributions with both finite and infinite means.

title: Design of Environment Aware Planning Heuristics for Complex Navigation Objectives
Creators: name: Bailey, Carter D.
Publisher: name: Utah State University
Year: 2022

description: A heuristic is the simplified approximations that helps guide a planner in deducing the best way to move forward. Heuristics are valued in many modern AI algorithms and decision-making architectures due to their ability to drastically reduce computation time. Particularly in robotics, path planning heuristics are widely leveraged to aid in navigation and exploration. As the robotic platform explores and navigates, information about the world can and should be used to augment and update the heuristic to guide solutions. Complex heuristics that can account for environmental factors, robot capabilities, and desired actions provide optimal results with little wasted exploration, but are computationally expensive. This thesis demonstrates results of research into simplifying heuristics that maintains the performance improvements from complicated heuristics.
The research presented is validated on two complex robotic tasks: stealth planning and energy efficient planning. The stealth heuristic was created to inform a planner and allow a ground robot to navigate unknown environments in a less visible manner. Due to the highly uncertain nature of the world (where unknown observers exist) this heuristic implemented was instrumental to enabling the first high-uncertainty stealth planner. Heuristic guidance is further explored for use in energy efficient planning, where a machine learning approach is used to generate a heuristic measure. This thesis demonstrates effective learned heuristics that simplify convergence time and accounts for the complexities of environment. A reduction of 60% in required compute time for planning was found.

description: Vitamin D plays an important pleiotropic role in maintaining global homeostasis of the human body. Its functions go far beyond skeletal health, playing a crucial role in a plethora of cellular functions, as well as in extraskeletal health, ensuring the proper functioning of multiple human organs, including the skin. Genes from the Grainyhead-like (GRHL) family code for transcription factors necessary for the development and maintenance of various epithelia. Even though they are involved in many processes regulated by vitamin D, a direct link between vitamin D-mediated cellular pathways and GRHL genes has never been described. We employed various bioinformatic methods, quantitative real-time PCR, chromatin immunoprecipitation, reporter gene assays, and calcitriol treatments to investigate this issue. We report that the vitamin D receptor (VDR) binds to a regulatory region of the Grainyhead-like 1 (GRHL1) gene and regulates its expression. Ectopic expression of VDR and treatment with calcitriol alters the expression of the GRHL1 gene. The evidence presented here indicates a role of VDR in the regulation of expression of GRHL1 and correspondingly a role of GRHL1 in mediating the actions of vitamin D.

description: Genetic selection of dairy animals until the early 2000s was focused on productive traits while disregarding reproductive traits. It is believed that such selection strategy was associated with compromised estrous expression and reproductive performance. Since the mid 2000s, genetic selection of dairy breeds has included reproductive traits. We hypothesized that genomic breeding values for daughter pregnancy rate (GDPR) and heifer conception rate (GHCR) are associated with estrous characteristics. Therefore, the objectives of the current experiment were to evaluate the association among GDPR and GHCR with estrous characteristics measured by an automated device.

title: Dust Deposition Changes Production, Chlorophyll-a and Community Composition in Mountain Lakes
Creators: name: Wen, Jiahao
Publisher: name: Utah State University
Year: 2022

description: Increasing quantities of dust emitted from semi-arid soils, agricultural soils, and urban regions are blown to remote mountain lakes in the American West. Remote mountain lakes lacking local nutrient inputs and presenting simple food webs that are easily affected by climate changes. Dust can carry nutrients (e.g., nitrogen and phosphorus) to mountain lakes and potentially enhance algae growth and change algal communities. However, experimental tests of this hypothesis are lacking. Using in situ experiments, we investigated the effects of dust enrichment on the production, biomass, and primary algal species in three mountain lakes in the American West. We found that dust additions increased algal biomass at all three lakes, but the magnitude differed, ranging from 32% to 226%. This variation may be associated with the initial algal biomass before the experiments and nutrient limitation of lakes (limited by nitrogen, phosphorus, or both). Surprisingly, bioassays with increased dust additions showed decreased 14C primary productivity (the ability to fix carbon). The first reason could be that dust inputs stimulated bacteria that could fix carbon under dark conditions while suppressing algal production that can fix carbon during the day. The second reason could be that nutrient-limited algae allocated energy to uptake dust nutrients instead of fixing carbon after the dust was added. The relative abundance of algal species changed in dust treatments compared to the controls. Mixotrophs (algal species that both photosynthesize and take up organic matter or eat other plankton) increased at Castle Lake but decreased at the other lakes compared to phototrophs (species that only photosynthesize). Our study presented experimental evidence on how dust deposition influences remote mountain lakes. We proposed the hypothesis that the pre-existing status of the lake may affect the responses of dust inputs. This hypothesis needs to be tested in the future.

description: We discuss a Rydberg atom chain with a tunable blockade radius from the gauge theoretic perspective. When the blockade radius is one lattice spacing, this system can be formulated in terms of the PXP model, and there is a $\mathbb{Z}_2$ Ising phase transition known to be equivalent to a confinement-deconfinement transition in a gauge theory, the lattice Schwinger model. Further increasing the blockade radius, one can add a next-nearest neighbor (NNN) interaction into the PXP model. We discuss the interpretation of NNN interaction in terms of the gauge theory and how finite NNN interaction alters the deconfinement behavior and propose a corresponding experimental protocol. When the blockade radius reaches two lattice spacing, the model reduces to the PPXPP model. A novel gauge theory equivalent to the PPXPP model is formulated, and the phases in the two formulations are delineated. These results are readily explored experimentally in Rydberg quantum simulators.

description: With the race to build large-scale quantum computers and efforts to exploit quantum algorithms for efficient problem solving in science and engineering disciplines, the requirement to have efficient and scalable verification methods are of vital importance. We propose a novel formal verification method that is targeted at Quantum Fourier Transform (QFT) circuits. QFT is a fundamental quantum algorithm that forms the basis of many quantum computing applications. The verification method employs abstractions of quantum gates used in QFT that leads to a reduction of the verification problem from Hilbert space to the quantifier free logic of bit-vectors. Very efficient decision procedures are available to reason about bit-vectors. Therefore, our method is able to scale up to the verification of QFT circuits with 10,000 qubits and 50 million quantum gates, providing a meteoric advance in the size of QFT circuits thus far verified using formal verification methods.

title: The Relationship Between Bird Species Richness and Human Appropriation of Net Primary Productivity

description: As humans harvest increasing amounts of biomass, it is crucial to gain an understanding of how much energy is being appropriated and the impact that this could have on ecosystems and biodiversity. The primary way in which humans impact biodiversity loss is through land use change. One way of quantifying the impact of land use change is through human appropriation of net primary production (HANPP). This measurement represents the total amount of energy derived from photosynthesis that humans remove from ecosystems and appropriate for their own use.My research studies the relationship between HANPP and bird species richness at the county level of the conterminous U.S. using a linear model with a spatial correlation structure. I produce a new dataset of bird species richness per county in 2001 from the USGS GAP species richness data. HANPP is negatively correlated with species richness, supporting the hypothesis that counties with higher HANPP had a lower number of bird species.Bird species richness, however, is overwhelmingly influenced by environmental and climatic factors such as coastal proximity and temperature.
title: Analysis of Substrate Specificity and Dimer Disruption in Protein Arginine Methyltransferases

description: Each of us begins life as a single cell containing our DNA and a complement of varied pieces of machinery capable of reading and acting on information stored in the genome. The cell copies itself and each copy makes copies. As this cycle repeats, different lineages of cells begin to take on different roles, eventually maturing into the different tissues and organs that make up a healthy organism. All of this requires exquisite coordination which requires different cells, and different parts of a cell, to be able to communicate with one another. How the mindless components of mindless cells manage to transmit and respond to information is one of the more interesting questions in biology. While there is no single mechanism by which cells communicate, one common mechanism uses a process termed post-translational modification. In this process a protein (which is a specific type of cellular machinery) is modified, typically by the addition of a small chemical group, and this modification changes the function of the modified protein. One type of post-translational modification is called arginine methylation, in which a particular component (arginine) of certain proteins is modified by the addition of a methyl group. Arginine methylation is involved in normal cellular processes such as cellular replication and the manufacture of new proteins, and it is involved in stress responses such as DNA repair and cellular self-destruction. Arginine methylation is conducted by a family of proteins called protein arginine methyltransferases (PRMTs). These proteins are manufactured in all eukaryotes and in all tissues. Their malfunction has been associated with several human diseases including cardiovascular disease and cancer. The processes that cause these proteins to malfunction are not well understood, nor are the basic mechanisms that drive their function. Here we describe our work toward understanding features that allow the PRMTs to recognize other proteins they need to modify, and our work characterizing a mechanism that may drive PRMT dysfunction in cancer. This work will improve our understanding of PRMT biochemistry, the roles of the PRMTs in cellular biology, and may help lead to the development of new treatments for human diseases.

description: We study structural and magnetic properties of rare-earth based semimetals RAuGe (R = Y, Gd-Tm, and Lu) using flux-grown single crystals. These compounds belong to the noncentrosymmetric polar space group P63mc. We confirm the systematic structural evolution at room temperature as a function of ionic radius of rare earths to clarify the isopointal crossover between two polar structures: three-dimensional LiGaGe-type and quasi-two-dimensional NdPtSb-type. Magnetism shows a characteristic anisotropy in reasonable agreement with the crystal electric field (CEF) theory; the easy-plane-type anisotropy for R = Tb and Dy turns into the Ising-type anisotropy for R = Er and Tm. We evaluate the CEF parameters based on the Stevens operators to reasonably reproduce the temperature dependence of magnetic susceptibilities and specific heat for RAuGe (R = Tb-Tm). The estimated energy scale of the Ising gap (~ 11 meV) in TmAuGe is consistent with an excitation observed in an inelastic neutron scattering experiment. These findings suggest an opportunity for interplay between conduction electrons and nontrivial spin structures in the family of magnetic polar semimetals RAuGe.

ALMA Observations Show Major Mergers Among the Host Galaxies of Fast-growing, High-redshift Supermassive Black Holes

description: We present new ALMA band-7 data for a sample of six luminous quasars at z~4.8, powered by fast-growing supermassive black holes (SMBHs) with rather uniform properties: the typical accretion rates and black hole masses are L/L_Edd~0.7 and M_BH~10^9 M_sol. Our sample consists of three "FIR-bright" sources, which were individually detected in previous Herschel/SPIRE observations, with star formation rates of SFR>1000 M_sol/yr, and three "FIR-faint" sources for which Herschel stacking analysis implies a typical SFR of ~400 M_sol/yr. The dusty interstellar medium in the hosts of all six quasars is clearly detected in the ALMA data and resolved on scales of ~2 kpc, in both continuum (λ_rest ~150 um) and [C II]157.74 um line emission. The continuum emission is in good agreement with the expectations from the Herschel data, confirming the intense SF activity in the quasar hosts. Importantly, we detect companion sub-millimeter galaxies (SMGs) for three sources -- one FIR-bright and two FIR-faint, separated by ~14-45 kpc and <450 km/s from the quasar hosts. The [C II]-based dynamical mass estimates for the interacting SMGs are within a factor of ~3 of the quasar hosts' masses, while the continuum emission implies SFR(quasar)~(2-11)xSFR(SMG). Our ALMA data therefore clearly support the idea that major mergers are important drivers for rapid early SMBH growth. However, the fact that not all high-SFR quasar hosts are accompanied by interacting SMGs and the gas kinematics as observed by ALMA suggest that other processes may be fueling these systems. Our analysis thus demonstrates the diversity of host galaxy properties and gas accretion mechanisms associated with early and rapid SMBH growth.
