description: The non-equilibrium gas dynamics is described by the Boltzmann equation, which can be solved numerically through the deterministic and stochastic methods. Due to the complicated collision term of the Boltzmann equation, many kinetic relaxation models have been proposed and used in the past seventy years for the study of rarefied flow. In order to develop a multiscale method for the rarefied and continuum flow simulation, by adopting the integral solution of the kinetic model equation a DVM-type unified gas-kinetic scheme (UGKS) has been constructed. The UGKS models the gas dynamics on the cell size and time step scales while the accumulating effect from particle transport and collision has been taken into account within a time step. Under the UGKS framework, a unified gas-kinetic wave-particle (UGKWP) method has been further developed for non-equilibrium flow simulation, where the time evolution of gas distribution function is composed of analytical wave and individual particle. In the highly rarefied regime, particle transport and collision will play a dominant role. Due to the single relaxation time model for particle collision, there is a noticeable discrepancy between the UGKWP solution and the full Boltzmann or DSMC result, especially in the high Mach and Knudsen number cases. In this paper, besides the kinetic relaxation model, a modification of particle collision time according to the particle velocity will be implemented in UGKWP. As a result, the new model greatly improves the performance of UGKWP in the capturing of non-equilibrium flow. There is a perfect match between UGKWP and DSMC or Boltzmann solution in the highly rarefied regime. In the near continuum and continuum flow regime, the UGKWP will gradually get back to the macroscopic variables based Navier-Stokes flow solver at small cell Knudsen number.

description: The structure of the caudal portion of a vertebral column belonging to a complete phytosaur skeleton is described. The skeleton has been collected from the Calcare di Zorzino (Zorzino Limestone) of Norian (Late Triassic) age, in the small quarry of Endenna (Bergamo, Lombardy, Northern Italy). The specimen is currently being prepared, and only a detailed description of the tail is possible. The exposed portion of the skull, which shows, among other characters, a narrow, flattened snout, suggests possible relationships with the genus Mystriosuchus, but preparation of the skull must be finished prior to attempting any classification. The morphology of the tail vertebrae has never been figured for phytosaurs; however, the structure of the tail vertebrae of this specimen reflects a great degree of adaptation toward aquatic life, justifying its description prior to complete preparation. If this specimen represents a new species, it should have been highly specialised toward marine life than most other phytosaurs in which the postcranial skeleton is known.

Multi-Group Discontinuous Asymptotic $P_1$ Approximation in Radiative Marshak Waves Experiments

description: We study the propagation of radiative heat (Marshak) waves, using modified $P_1$-approximation equations. In relatively optically-thin media the heat propagation is supersonic,~i.e. hydrodynamic motion is negligible, and thus can be described by the radiative transfer Boltzmann equation, coupled with the material energy equation. However, the exact thermal radiative transfer problem is still difficult to solve and requires massive simulation capabilities. Hence, there still exists a need for adequate approximations that are comparatively easy to carry out. Classic approximations, such as the classic diffusion and classic $P_1$, fail to describe the correct heat wave velocity, when the optical depth is not sufficiently high. Therefore, we use the recently developed discontinuous asymptotic $P_1$ approximation, which is a time-dependent analogy for the adjustment of the discontinuous asymptotic diffusion for two different zones. This approximation was tested via several benchmarks, showing better results than other common approximations, and has also demonstrated a good agreement with a main Marshak wave experiment and its Monte-Carlo gray simulation. Here we derive energy expansion of the discontinuous asymptotic $P_1$ approximation in slab geometry, and test it with numerous experimental results for propagating Marshak waves inside low density foams. The new approximation describes the heat wave propagation with good agreement. Furthermore, a comparison of the simulations to exact implicit Monte-Carlo slab-geometry multi-group simulations, in this wide range of experimental conditions, demonstrates the superiority of this approximation to others.

Proton NMR measurements of the local magnetic field in the paramagnetic metal and antiferromagnetic insulator phases of $λ$-(BETS)$_{2}$FeCl$_{4}$

description: Measurements of the $^{1}$H-NMR spectrum of a small ($\sim$ 4 $μ$g) single crystal of the organic conductor $λ$-(BETS)$_{2}$FeCl$_{4}$ are reported with an applied magnetic field $\bf{B}$$_{0}$ = 9 T parallel to the a-axis in the $ac$-plane over a temperature $(T)$ range 2.0 $-$ 180 K. They provide the distribution of the static local magnetic field at the proton sites in the paramagnetic metal (PM) and antiferromagnetic insulator (AFI) phases, along with the changes that occur at the PM$-$AFI phase transition. The spectra have six main peaks that are significantly broadened and shifted at low $T$. The origin of these features is attributed to the large dipolar field from the 3d Fe$^{3+}$ ion moments (spin $S_{\rm{d}}$ = 5/2). Their amplitude and $T-$dependence are modeled using a modified Brillouin function that includes a mean field approximation for the total exchange interaction ($J_{0}$) between one Fe$^{3+}$ ion and its two nearest neighbors. A good fit is obtained using $J_{0}$ = $-$ 1.7 K. At temperatures below the PM$-$AFI transition temperature $T_{MI}$ = 3.5 K, an extra peak appears on the high frequency side of the spectrum and the details of the spectrum become smeared. Also, the rms linewidth and the frequency shift of the spectral distribution are discontinuous, consistent with the transition being first-order. These measurements verify that the dominant local magnetic field contribution is from the Fe$^{3+}$ ions and indicate that there is a significant change in the static local magnetic field distribution at the proton sites on traversing the PM to AFI phase transition.

description: As the largest radio telescope in the world, the Square Kilometre Array (SKA) will lead the next generation of radio astronomy. The feats of engineering required to construct the telescope array will be matched only by the techniques developed to exploit the rich scientific value of the data. To drive forward the development of efficient and accurate analysis methods, we are designing a series of data challenges that will provide the scientific community with high-quality datasets for testing and evaluating new techniques. In this paper we present a description and results from the first such Science Data Challenge (SDC1). Based on SKA MID continuum simulated observations and covering three frequencies (560 MHz, 1400MHz and 9200 MHz) at three depths (8 h, 100 h and 1000 h), SDC1 asked participants to apply source detection, characterization and classification methods to simulated data. The challenge opened in November 2018, with nine teams submitting results by the deadline of April 2019. In this work we analyse the results for 8 of those teams, showcasing the variety of approaches that can be successfully used to find, characterise and classify sources in a deep, crowded field. The results also demonstrate the importance of building domain knowledge and expertise on this kind of analysis to obtain the best performance. As high-resolution observations begin revealing the true complexity of the sky, one of the outstanding challenges emerging from this analysis is the ability to deal with highly resolved and complex sources as effectively as the unresolved source population.

description: (Abridged) The projected structures and integrated properties of the Andromeda I, II, III, V, VI, VII and Cetus dwarf spheroidal galaxies are analysed based upon resolved counts of red giant branch stars. For each object, we have derived isopleth maps, surface brightness profiles, absolute magnitudes, central surface brightnesses, and a large number of other morphological parameters. Our analysis probes to larger radius and fainter surface brightnesses than most previous studies and as a result we find that the galaxies are generally larger and brighter than has previously been recognised. In particular, the luminosity of Andromeda V is found to be consistent with the higher metallicity value which has been derived for it. Andromeda I shows strong evidence of tidal disruption and S-shaped tidal tails are clearly visible. On the other hand, Cetus does not show any evidence of tidal truncation, let alone disruption. Andromeda II shows compelling evidence of a large excess of stars at small radius and suggests that this galaxy consists of a secondary core component. Comparing the M31 dwarf spheroidal population with the Galactic population, we find that the scale radii of the M31 population are larger than those for the Galactic population by at least a factor of two, for all absolute magnitudes. We also find that the two populations are offset from one another in the central surface brightness - luminosity relation. Finally, we find that the M31 dwarf spheroidals show the same correlation with distance-from-host as shown by the Galactic population, such that dwarf spheroidals with a higher central surface brightness are found further from their host. This again suggests that environment plays a significant role in dwarf galaxy evolution.

description: We answer the long-standing question of which production mechanism is responsible for the cataclysmic variables (CVs) in globular clusters. Arguments have been given that range from mostly primordial presence to a significant contribution of later dynamical formation in close stellar encounters. We conclude, based on a thorough analysis of a homogeneous {\it Chandra} data set, that the majority of CVs in globulars has a dynamical origin.

description: We have measured the superconducting critical temperature (Tc) and the diamagnetic susceptibility of La2-xSrxCuO4 single crystals in various magnetic fields. We observed a field-induced evolution from an apparent Tc phase to an intrinsic Tc1 = 15 K or Tc2 = 30 K phase characterized by "magic" hole concentration which is commensurate with that of a two dimensional electronic lattice. The onset Tc of the intrinsic superconducting phases remains robust up to H = 5 Tesla. We suggest that the intrinsic superconducting phases at "magic" doping concentrations are the pristine electronic phases of high temperature superconductivity.

description: A child’s health is strongly affected by the family and community environment in which he or she lives, learns and plays, as well as by access to high-quality health care, high-quality early learning and educational opportunities, and nurturing relationships with parents and other adults. Reducing disparities in child health requires community-based strategies and health care policies that support children’s healthy development at home, at school and in the community. Health insurance and health care are vital to children’s health status as a means of preventing or mitigating health problems and educating families about health issues. Health disparities are associated with family income, educational status, race and ethnicity, and geography. Poor and low-income children have higher rates of mortality and disability than higher income children and are more likely to be in fair or poor health. Research shows that as neighborhood poverty levels increase, child well-being and opportunities for success decrease. One in ten Rhode Island children lives in a neighborhood of concentrated poverty (defined as census tracts with poverty rates of 30% or more). African American and Latino children are more likely than White children to live in these neighborhoods. Black and Latino children are more likely to be in poor health than their White counterparts. Children who are poor, of color or uninsured are more likely to lack access to appropriate health care. Rhode Island’s children are diverse in terms of race, ethnicity and income. In 2010 in Rhode Island, 72% of children under age 18 were White, 8% were Black or African-American, 3% were Asian, less than 1% were Native American, 9% were Some other race and 7% were Two or more races. Twenty-one percent of Rhode Island children were Hispanic.

Home alone : the experiences of home support workers in a climate of health care reform
Creators: name: Aitken, Jennifer Allison
Publisher: name: University of British Columbia
Year: 2009

description: The transition from institutional to home based health care relies heavily on the caring work of Home Support Workers (HSWs). Despite the importance of their labor, HSWs are under paid, under valued and misunderstood. Policy guiding home based care does little to alleviate this paradox. Therefore, the purpose of this study is to improve understanding about the ways home care policy impacts the caring experience. The question posed is, What are the experiences of Home Support Workers providing care to cognitively impaired elderly people in the community? A feminist approach is applied in this qualitative study. Unstructured, interviews conducted with a sample of three HSWs where succeeded by a focus group of leaders in the home support industry. Findings reveal an emotional component to their caring work which is hidden and unrecognized. A model for integrating HSWs into the interdisciplinary care team is proposed. Limitations of the study and future research are discussed. The timeliness of this topic, and the critical inequities inherent in the home support industry makes this study particularly relevant to social work.

description: For conventional ion traps, the trapping potential is close to independent of the electronic state, providing confinement for ions dependent primarily on their charge-to-mass ratio $Q/m$. In contrast, storing ions within an optical dipole trap results in state-dependent confinement. Here we experimentally study optical dipole potentials for $^{138}\mathrm{Ba}^+$ ions stored within two distinctive traps operating at 532 nm and 1064 nm. We prepare the ions in either the $6\mathrm{S}_{\mathrm{1/2}}$ electronic ground or the $5\mathrm{D}_{\mathrm{3/2}}$/ $5\mathrm{D}_{\mathrm{5/2}}$ metastable excited state and probe the relative strength and polarity of the potential. On the one hand, we apply our findings to selectively remove ions from a Coulomb crystal, despite all ions sharing the same $Q/m$. On the other hand, we deterministically purify the trapping volume from parasitic ions in higher-energy orbits, resulting in reliable isolation of Coulomb crystals down to a single ion within a radio-frequency trap.

description: We study the properties of two dimensional topological spin hall insulators which arise through spontaneous breakdown of spin symmetry in systems that are spin rotation invariant. Such a phase breaks spin rotation but not time reversal symmetry and has a vector order parameter. Skyrmion configurations in this vector order parameter are shown to have electric charge that is twice the electron charge. When the spin Hall order is destroyed by condensation of skyrmions superconductivity results. This may happen either through doping or at fixed filling by tuning interactions to close the skyrmion gap. In the latter case the superconductor- spin Hall insulator quantum phase transition can be second order even though the two phases break distinct symmetries.

description: Three sphinctozan sponges: Amblysiphonella sp., Colospongia sp. and the new species Deningeria iannacei n. sp., are described from a loose boulder derived from Triassic dolomites ("Dolomia principale") of the Argentino valley in Northern Calabria (Southern Italy). All three genera are reported for the first time from Calabria. The sphinctozoans are associated with other sponges (inozoans, "sphinctozoans," "hydrozoans", chaetetids), "microproblematica", foraminifers, abundant worm tubes, biogenic crusts, and rare dasycladacean algae. The age of the association is referred to Upper Triassic (Norian-Rhaetian) on the basis of its similarity to the classic reef assemblages of Upper Triassic in the Tethys realm and by the close proximity of the boulder to the well dated (macrofauna) outcropping Upper Triassic carbonate successions.

description: The globular cluster G1 (Mayall II) in M31 is the most massive (~10^7 M_sun) stellar cluster in the Local Group, and it has the highest central velocity dispersion (~28 km/s). It has been claimed to host a central ~20,000 M_sun black hole, but these claims have been controversial. We report here the XMM-Newton detection of X-ray emission from G1 at a level of Lx ~ 2x10^{36} erg/s. This emission could be the result of Bondi-Hoyle accretion of ionized cluster gas by a central black hole, or it could be produced by a conventional low-mass X-ray binary. A precise localization of the X-ray emission, which is not possible with the current XMM data, could distinguish between these possibilities. While such a measurement may be difficult, it is of sufficient potential importance to pursue.

BIOCHRONOLOGY OF THE PLEISTOCENE MAMMAL FAUNA FROM PONTE GALERIA (ROME) AND REMARKS ON THE MIDDLE GALERIAN FAUNAS

description: Taking into account the fossil mammal material recently discovered at Cava di Breccia (sands outcropping at Ponte Galeria, Rome), the revised fossils from the area and the updated stratigraphical settings of the Ponte Galeria Formation (Rome), the Authors discuss the biochronology of the Middle Galerian faunal assemblages with a new definition of its Faunal Units.
1) The mammal fauna of Isernia in our opinion is strongly conditioned by palaeoenvironmental factors and by human influence. The occurrence at Isernia La Pineta of the rodent Arvicola cantiana, which was widespread in Western Europe from 0.6 MA, does not match with the biochronology of the fauna and with the absolute dating (0.736 MA). A new radiometric dating will be useful to determine the age of the Isernia La Pineta local fauna, which can be considered younger than 0.736 MA on the basis of its faunal assemblage.  2) The age of the faunal assemblage of Ponte Galeria is between 0.8 and 0.75 MA, approximately in correspondence with the Brunhes-Matuyama paleomagnetic reversal event. The first occurrence of Bos galerianus and Megaloceros savini testifies a faunal renewal in comparison with the faunal assemblage of Slivia. The megacerine cervids from Ponte Galeria are more primitive than those from Isernia La Pineta and Venosa-Notarchirico. The Ponte Galeria local fauna has to be considered as a distinct Faunal Unit, younger than Slivia F.U. and older than the Isernia La Pineta fauna.

description: Multi-modal multi-objective optimization aims to find all Pareto optimal solutions including overlapping solutions in the objective space. Multi-modal multi-objective optimization has been investigated in the evolutionary computation community since 2005. However, it is difficult to survey existing studies in this field because they have been independently conducted and do not explicitly use the term "multi-modal multi-objective optimization". To address this issue, this paper reviews existing studies of evolutionary multi-modal multi-objective optimization, including studies published under names that are different from "multi-modal multi-objective optimization". Our review also clarifies open issues in this research area.

The "Bohr" Model for the High Tc Superconductivity

Year: 2006
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: We propose a charge crystal model that captures all the essential physics of the high temperature superconductivity (HTS) in the long wavelength limit. Based on the recent transport and the far-infrared (far-IR) experiments, we argue that the three-dimensional (3D) ordering of the pinned two-dimensional (2D) square electronic lattice (EL) in each CuO2 plane is the building block of HTS. Incorporating the physical picture derived from the neutron scattering experiments, we demonstrate that our model presents a coherent picture of the HTS. We suggest that the charge crystal model serves as a model for the microscopic theory and, hence, offers the key to the mechanism for the HTS.

DISCOVERY OF PARATIROLITES FROM THE BELLEROPHON FORMATION (UPPER PERMIAN, DOLOMITES, ITALY)
Creators: name: POSENATO, RENATO
name: PRINOTH, HERWIG
Publisher: name: Università degli Studi di Milano
Year: 1999

description: The first discovery of Paratirolites in the western Tethys is here described. The ammonoid was collected in the debris of the Bellerophon Fm. near Santa Cristina Valgardena (Bolzano, Dolomites). The specimen is contained in a small slab made of marly dark grey limestone with a biomicrofacies dominated by ostracods. It probably comes from the Ostracod Assemblage beds (Badiota Facies), which are situated few metres below the Comelicania beds. The occurrence of Paratirolites allow us to date this segment of the upper Bellerophon Fm. to the late Dorashamian, and to define the Comelicania and Nankinella beds of the Dolomites as younger than the Phisonites - Comelicania (= Gruntallina) beds of the Transcaucasia (basal Dorashamian). This assemblage is equivalent to or younger than the Paratirolites Zone (late Dorashamian).

LATE DEVONIAN-CARBONIFEROUS CONODONTS FROM EASTERN IRAN
Creators: name: YAZDI, MEHDI
Publisher: name: Università degli Studi di Milano
Year: 1999

description: Conodont data from acid-leaching 110 samples from two Late Devonian-Carboniferous areas in the Shotori Range (Tabas region) of eastern Iran are presented. At Howz-e-Dorah, a section (88 samples) commencing high in the Bahram Formation (Givetian-early Frasnian) extended through the Shishtu Formation (Frasnian, Early hassi Zone or older, to latest Tournaisian, anchoralis-latus Zone) and the Sardar Formation (earliest Visean, texanus Zone, to late Namurian, sinuatus-corrugatus-sulcatus Zone) and into the Jamal Formation (Permian). Four less exhaustively sampled sections (22 samples) show the Kale Sardar area to be tectonically more complicated than the Howz-e-Dorah area. Useful marker horizons in the Howz-e-Dorah section, well constrained by conodont data, are: the early Frasnian (no older than Early hassi Zone) biostromal beds of the Shishtu Formation, an early Famennian (Late triangularis to Early crepida) interval of oolitic limestone, a cyclothem sequence straddling the Early Carboniferous-Late Carboniferous boundary, and an Early Permian interval of siliceous sand ("the white quartzite" of previous authors). Additionally, several iron-rich horizons, readily traceable from locality to locality, are well constrained by conodont ages. Eighty-five conodont species/subspecies are documented representing 24 genera.. Two new species, Polygnathus capollocki and Polygnathus ratebi and one new subspecies, Icriodus alternatus mawsonae are described.

description: Extensive tracts of Devonian and older sedimentary and igneous units occur within the axial region of the western Karakoram Block of northernmost Pakistan over a distance in excess of 200 km between the the headwaters of the Karambar valley in northwestern Gilgit Agency to southwestern Chitral. Conodont data indicate that the oldest sedimentary unit so far discriminated within this belt, the Yarkhun Formation, includes horizons of Ordovician (Arenig) age, consistent with an earlier-presented acritarch-based Arenig age for part of the same unit. Conodont data from the "Lun Shales", a stratigraphic potpourri with little-known Silurian and Devonian tracts, demonstrate the presence of Early Devonian (early Emsian) horizons. The Shogrâm Formation, widely distributed through the region, spans an appreciable interval of the Middle and Late Devonian mid-Givetian through until at least early Famennian. A major lacuna in sedimentation may be present, represented by all or most of the earlier half of Frasnian time. A biostratigraphically and possibly biogeographically important new species, Icriodus homeomorphus, is described; it is encountered in horizons of early Famennian age (Late triangularis Zone to ?Early crepida Zone).

Solar Winds Driven by Nonlinear Low-Frequency Alfven Waves from the Photosphere : Parametric Study for Fast/Slow Winds and Disappearance of Solar Winds

description: (abridged) We investigate how the properties of the corona and solar wind in the open coronal holes depend on the properties of the magnetic fields and their footpoint motions at the surface, by perfoming 1D MHD simulations from the photosphere to 0.3 or 0.1AU. We impose low-frequency (<0.05Hz) transverse fluctuations of the field lines at the photosphere with various amplitude, spectrum, and polarization in the open flux tubes with different photospheric field strength, B, and super-radial expansion of the cross section, f_max. We find that a transonic solar wind is the universal consequence. The atmosphere is also stably heated up to >10^6K by the dissipation of the Alfven waves through compressive-wave generation and wave reflection in the case of the sufficient wave input with photospheric amplitude, > 0.7km/s. The density, and accordingly the mass flux, of solar winds show a quite sensitive dependence on because of an unstable aspect of the heating by the nonlinear Alfven waves. A case with =0.4km/s gives ~50 times smaller mass flux than the fiducial case for the fast wind with =0.7km/s; solar wind almost disappears only if becomes half. We also find that the solar wind speed has a positive correlation with B/f_max, which is consistent with recent observations. We finally show that both fast and slow solar winds can be explained by the single process, the dissipation of the low-frequency Alfven waves, with different sets of and B/f_max. Our simulations naturally explain the observed (i) anticorrelation of the solar wind speed and the coronal temperature and (ii) larger amplitude of the Alfvenic fluctuations in the fast winds. In Appendix, we also explain our implementation of the outgoing boundary condition of the MHD waves with some numerical tests.

description: A new realization of the International Celestial Reference Frame (ICRF) is presented based on the work achieved by a working group of the International Astronomical Union (IAU) mandated for this purpose. This new realization, referred to as ICRF3, is based on nearly 40 years of data acquired by very long baseline interferometry. The ICRF3 includes positions at 8.4 GHz for 4536 sources, supplemented with positions at 24 GHz for 824 sources and at 32 GHz for 678 sources, for a total of 4588 sources. A subset of 303 sources among these, uniformly distributed on the sky, are identified as "defining sources" and as such serve to define the axes of the frame. Source positions are reported for epoch 2015.0 and must be propagated for observations at other epochs for the most accurate needs, accounting for the acceleration toward the Galactic center, which results in a dipolar proper motion field of amplitude 0.0058 milliarcsecond/yr (mas/yr). The frame shows a median positional uncertainty of about 0.1 mas in right ascension and 0.2 mas in declination, with a noise floor of 0.03 mas in the individual source coordinates. A subset of 500 sources is found to have extremely accurate positions at 8.4 GHz, in the range of 0.03 to 0.06 mas. Comparing ICRF3 with the Gaia Celestial Reference Frame 2 in the optical domain, there is no evidence for deformations larger than 0.03 mas between the two frames. Significant positional offsets between the three ICRF3 frequencies are detected for about 5% of the sources. Moreover, a notable fraction (22%) of the sources shows optical and radio positions that are significantly offset. There are indications that these positional offsets may be the manifestation of extended source structures. This third realization of the ICRF was adopted by the IAU at its 30th General Assembly in August 2018 and replaced the previous realization, ICRF2, on January 1, 2019.

description: Brachiopods are described from two horizons of the Bachu Formation from the Bachu area of the Tarim Basin, Xinjiang Province, northwest China. We assign the brachiopods from the basal Bachu Formation to late Famennian and correlate those from its upper part to the Eochoristites-Martiniella Assemblage of South China, of early Tournaisian age. The brachiopod fauna of the Bachu Formation exhibits strong generic and specific links with coeval South Chinese faunas, suggesting a close biogeographical affinity with the South China block. Eleven species are described, including one new species, Ptychomaletoechia bachuensis sp. nov.

description: Understanding social behavior requires observing freely behaving animals in natural environments. Ecological context is required to ask meaningful questions in the lab. Further some behaviors only manifest in the wild. Unfortunately, the small rodents that are common in the lab are exceedingly difficult to observe in the wild. Prairie voles are a prominent model in social biology, important for the study of pair bonding, parental care and social buffering. Though prairie voles are socially monogamous, in natural environments pairing and territorial behavior vary with individual differences in neuroanatomy and with differences in population density. First, I tested the hypothesis that the retrosplenial cortex contributes to social and spatial memory in the field. Male prairie voles received retrosplenial cortex lesion or sham treatment. Then pair-bond formation was assessed with the partner preference test in the lab. Mated pairs were then radio-tracked in the field to assess pair-bond maintenance. Following tracking, male spatial memory was assessed with a homing test following a random displacement. Lesions disrupted partner preference in the lab and homing in the field, suggesting a role for the retrosplenial cortex in social behavior and demonstrating a contribution to spatial memory in the field. Second, I deployed an automated radio-telemetry system in the field to better monitor social behavior of freely living prairie voles. I radio-mapped the field site and radio tracked 48 prairie voles. These data were used to train nonlinear least-squares, nonparametic, and Bayesian trilateration localization models. The most accurate model (the Bayesian trilateration) had a median fix error of 4.5 m. The system was then used to observe the activity of freely living prairie voles, uncovering both circadian and ultradian patterns of behavior. Finally, I use our automated telemetry system to detect differences in social behavior using active-RFID and Bayesian trilateration approaches. Three cohorts of 48 prairie voles were tracked at low and high population densities by manual and automated radiotelemetry. Pairing, territorial classification, same-sex, and opposite sex encounter rates were estimated and compared for each method. Despite lower per-fix accuracy Bayesian trilateration was found to have the best agreement with manual telemetry inference of social behavior. Hopefully these studies will provide ecological validation and new observational tools for the study of prairie vole social behavior in the lab and field
