Neonatal jaundice is very common problem encountered s in the newborns. It is observed during the first week of life in around 60 % of term and 80 % of preterm babies. The initial sign of hearing loss is very subtle and systematic neonatal hearing screening methods are the most effective means of early detection. Early diagnosis and intervention are decisive factors in development and prognosis of these children.

(Caracal)
MATERIAL EXAMINED. — CD 9172, a left 1st metacarpal.
DESCRIPTION AND TAXONOMIC ASSIGNMENT
 This specimen is complete, but heavily encrusted with pyrolusite. From the size (total length = 18.5 mm) and visible morphology it is a good match for caracal. Note that the specimen (CD 324) tentatively identified as a lower carnassial of a caracal in Berger et al. (2003) is the posterior portion of a very heavily damaged P 4 and is not identifiable.

description: Micro/nanoscale single photon source is a building block of on-chip quantum information devices. Owing to possessing ultrasmall optical mode volume, plasmon structures can provide large Purcell enhancement, however scattering and absorption are two barriers to prevent them from being used in practice. To overcome these barriers, we propose the topological photonic structure containing resonant plasmon nanoantenna, where nanoantenna provides large Purcell enhancement while topological photonic crystal guides all scattering light into its edge state. Through the optical mode design, the rate of single photons emitted into the edge state reaches more than 104γ0 simultaneously accompanied with an obvious reduction of absorption. This kind of nonscattering large Purcell enhancement will provide new sight for on-chip quantum light sources such as a single photon source and nanolaser.

description: We examine the dynamics of a closed cosmology whose matter source is that of a conformally coupled scalar field with a broken ${\rm SO}(1,1)$ symmetry, which correspond to the $α$-attractors proposed by Linde and Kallosh. Following a field redefinition, such models give rise to "T-model" inflationary potentials, whose dynamics provide both an inflationary phase and a classical bounce. We show that the universe can undergo bounces far from the regime of quantum gravity. We analyse perturbations on this background with particular attention given to the effects of a double-bouncing scenario (with rapid recollapse between bounces) on the long wavelength modes. We demonstrate that the predictions of such models agree well with observations and might explain the suppression of power in the low multiples of the CMB.

Resonance Behavior and Partial Averaging in a Three-Body System with Gravitational Radiation Damping

description: In a previous investigation, a model of three-body motion was developed which included the effects of gravitational radiation reaction. The aim was to describe the motion of a relativistic binary pulsar that is perturbed by a third mass and look for resonances between the binary and third mass orbits. Numerical integration of an equation of relative motion that approximates the binary gives evidence of such resonances. These $(m:n)$ resonances are defined for the present purposes by the resonance condition, $mω=2nΩ$, where $m$ and $n$ are relatively prime integers and $ω$ and $Ω$ are the angular frequencies of the binary orbit and third mass orbit, respectively. The resonance condition consequently fixes a value for the semimajor axis $a$ of the binary orbit for the duration of the resonance because of the Kepler relationship $ω=a^{-3/2}$. This paper outlines a method of averaging developed by Chicone, Mashhoon, and Retzloff which renders a nonlinear system that undergoes resonance capture into a mathematically amenable form. This method is applied to the present system and one arrives at an analytical solution that describes the average motion during resonance. Furthermore, prominent features of the full nonlinear system, such as the frequency of oscillation and antidamping, accord with their analytically derived formulae.

Portable preservation
Personal digital archiving

description: Personal (Digital) Archiving. A concept often talked about, but one that is often difficult to realise in practice, especially for individuals, minority and indigenous peoples, and communities without access to significant resources. Many individuals/groups have specialised knowledge relating to subjects of great personal interest. However, more often than not, these people/groups don't have the resources/know-how to record this information in sufficient detail, with sufficient surrounding meta data to make it of use to scholars worldwide. To an extent, projects such as Wikipedia, Project Gutenberg (http://www.gutenberg.org/), Europeana (http://www.europeana1914-1918.eu/en) have allowed basic recording and cataloguing to take place. Indeed the written word, sound, and two dimensional imagery have been transformed by modern recording tools. However, the current widely available tools still leave a lot to desired, particularly when it comes to preparing the data for “proper” preservation. Anything beyond the basic scan/photograph/record/video also tends to require specialised (for specialised read big, bulky and expensive) equipment and operators. But what if such individuals/groups could have access to a cheap portable workstation for preservation? Preservation in a box? The cost of recording devices and techniques is falling all the time. It should now be possible to create a "standards compliant" low-cost digital preservation workstation using standard, widely available, cheap technology and open source software and hardware (see http://www.diybookscanner.org/). These workstations could record (and OCR) books, paintings, objects), spatial info, non-invasive material/composition sampling, related ephemera (like instruction books), etc. Couple such a device to a 3d printer, large format printer, digital book printer and you can reproduce copies for people to handle (imagine the impact of handling a replica bone harpoon head, or reproduction of an actual d-day map) In this poster I intend to explore how such a device could be built using standard, cheap components and present a design concept for a prototype.

description: We investigate the irreversibility of entanglement distillation for a symmetric d-1 parameter family of mixed bipartite quantum states acting on Hilbert spaces of arbitrary dimension d x d. We prove that in this family the entanglement cost is generically strictly larger than the distillable entanglement, such that the set of states for which the distillation process is asymptotically reversible is of measure zero. This remains true even if the distillation process is catalytically assisted by pure state entanglement and every operation is allowed, which preserves the positivity of the partial transpose. It is shown, that reversibility occurs only in cases where the state is quasi-pure in the sense that all its pure state entanglement can be revealed by a simple operation on a single copy. The reversible cases are shown to be completely characterized by minimal uncertainty vectors for entropic uncertainty relations.

Einstein Gravity as an emergent phenomenon?

description: In this essay we marshal evidence suggesting that Einstein gravity may be an emergent phenomenon, one that is not ``fundamental'' but rather is an almost automatic low-energy long-distance consequence of a wide class of theories. Specifically, the emergence of a curved spacetime ``effective Lorentzian geometry'' is a common generic result of linearizing a classical scalar field theory around some non-trivial background. This explains why so many different ``analog models'' of general relativity have recently been developed based on condensed matter physics; there is something more fundamental going on. Upon quantizing the linearized fluctuations around this background geometry, the one-loop effective action is guaranteed to contain a term proportional to the Einstein--Hilbert action of general relativity, suggesting that while classical physics is responsible for generating an ``effective geometry'', quantum physics can be argued to induce an ``effective dynamics''. This physical picture suggests that Einstein gravity is an emergent low-energy long-distance phenomenon that is insensitive to the details of the high-energy short-distance physics.

A metasomatized lithospheric mantle contribution to the genesis of Li-rich magmas in slab-window settings

description: The geological factors controlling Li abundances in the mantle and mantle-derived magmas rising through the continental lithosphere, as well as their implications for Li ore genesis in the shallow crust, are still under debate. Here, we look from the mantle source perspective at those mechanisms that may boost the Li inventory in continental arc magmas, by characterizing a set of sub-arc mantle xenoliths from the southern Andes (Coyhaique volcanic field, western Patagonia). The mineral trace element signatures and oxygen fugacity estimates (FMQ > +3) in these peridotite xenoliths are consistent with those expected for a mantle wedge fluxed by oxidizing, subduction-related silicate melts rich in slab-derived volatile components. However, our data support that subduction-related metasomatism did not enhance significantly the Li inventory of the sub-arc lithospheric mantle, at odds with the generally claimed major role of slab-derived fluids in enriching Li in the supra-subduction mantle wedge. Major and trace element compositions of minerals also record transient thermal and chemical anomalies fingerprinting the interaction with OIB-type alkaline melts, which percolated through the shallow (7.2-16.8 kbar) and hot (952-1054 °C) mantle wedge in response to the opening of an asthenosphere slab window and ridge collision. This alkaline metasomatism produced exceptionally high Li abundances (6-15 ppm) in metasomatic clinopyroxene, promoting the generation of a Li-rich and fertile lithospheric mantle wedge. A numerical model suggests that low degrees (< 10%) of partial melting of this alkaline-metasomatized sub-arc lithospheric mantle generates primitive melts having Li abundances (⁓13 ppm) much higher than average subduction-zone basalts. Extreme differentiation by fractional crystallization of these Li-rich magmas may provide an effective pathway for enhancing the fold enrichment process required for a magmatic rock to effectively source ore deposition in the shallow arc crust.

Estimation of dynamic networks for high-dimensional nonstationary time series

description: This paper is concerned with the estimation of time-varying networks for high-dimensional nonstationary time series. Two types of dynamic behaviors are considered: structural breaks (i.e., abrupt change points) and smooth changes. To simultaneously handle these two types of time-varying features, a two-step approach is proposed: multiple change point locations are first identified based on comparing the difference between the localized averages on sample covariance matrices, and then graph supports are recovered based on a kernelized time-varying constrained $L_1$-minimization for inverse matrix estimation (CLIME) estimator on each segment. We derive the rates of convergence for estimating the change points and precision matrices under mild moment and dependence conditions. In particular, we show that this two-step approach is consistent in estimating the change points and the piecewise smooth precision matrix function, under certain high-dimensional scaling limit. The method is applied to the analysis of network structure of the S\&P 500 index between 2003 and 2008.

description: Magma worlds, due to their hot, extended atmospheres are readily characterized spectroscopically by ground- and space-based telescopes, such as JWST. As yet, the lack of direct observations means that the nature and composition of these planets’ atmospheres are poorly constrained. Because the atmospheres of these planets are thought to be the result of chemical equilibrium with their interiors, their mass and composition are modulated by the solubilities of major gases in the magma. Therefore, we require a theoretical framework, informed by experimental data, to determine how volatile elements partition between the interior and atmosphere for diverse planetary compositions. However, there is limited experimental data on the solubilities of major atmosphere-forming gases in a range of silicate liquids relevant for exoplanets, which may be unlike that of the present-day Earth. To fill this gap, we performed new volatile (e.g., H, C, O) solubility experiments on exoplanet melt analog materials at high temperatures (≥ 1400 °C) using a 1-bar H2-CO2 gas-mixing furnace and an aerodynamic laser levitation furnace coupled to an FTIR spectrometer. We incorporate these experimental results into a new Python package (atmodeller), which computes chemical equilibrium at the melt-atmosphere interface of low-mass planets, from rocky worlds to sub-Neptunes. Given a set of planetary parameters (e.g., surface temperature, planetary mass, radius, mantle melt fraction) and initial volatile inventory, atmodeller uses experimentally calibrated solubility laws (including those determined from our experiments), together with free energy data for condensed and gas species, to determine how volatiles partition between the atmosphere and interior. Within the H-He-C-N-O-S-Cl system, we investigate a range of plausible atmospheric compositions and the impact of volatile dissolution into the interior for a set of known rocky exoplanets (e.g., the Trappist-1 system, 55 Cancri e) given current observational constraints from JWST. We also apply atmodeller to understand super-Earth and sub-Neptune atmospheres, simulating the effects of both volatile solubilities and non-ideal gas conditions for exoplanets like K2-18 b.

description: The magma ocean (MO) phase typically describes the early stage of rocky planets, during which the entire planet is molten due to heat generated by accretion processes. In the case of short-period exoplanets inside the runaway greenhouse limit, this phase may last Gyrs, until the inventory of major greenhouse gasses, such as H2O and H2, is exhausted. The internal evolution of these planets is influenced by various factors, including the exchange of volatiles between the molten planetary interior and the atmosphere. This exchange significantly impacts planetary climate, exoplanet bulk densities, surface conditions , and long-term geodynamic activity by controlling greenhouse effects, surface water stability, and atmospheric composition. This research focuses on modeling this interaction under different redox conditions. Using a coupled computational framework of the planetary interior and atmosphere, we study the detailed evolution of the magma oceans phase, aiming to understand the crystallization sequence and the resulting internal structure of the planet. We investigate the impact of the cooling sequence and evolving climatic conditions on mantle differentiation, mineralogy, formation of crusts, and the consequent composition of the atmosphere.

metadata

description: We have created tools that automate one of the most burdensome aspects of documenting the provenance of research data: describing data transformations performed by statistical software. Researchers in many fields use statistical software (SPSS, Stata, SAS, R, Python) for data transformation and data management as well as analysis. The C2Metadata ("Continuous Capture of Metadata for Statistical Data") Project creates a metadata workflow paralleling the data management process by deriving provenance information from scripts used to manage and transform data. C2Metadata differs from most previous data provenance initiatives by documenting transformations at the variable level rather than describing a sequence of opaque programs. Command scripts for statistical software are translated into an independent Structured Data Transformation Language (SDTL), which serves as an intermediate language for describing data transformations. SDTL can be used to add variable-level provenance to data catalogues and codebooks and to create "variable lineages" for auditing software operations. Better data documentation makes research more transparent and expands the discovery and re-use of research data.

description: Deforestation for cropland expansion in the sloping landscapes along the East African Rift system causes severe soil erosion and thus the loss of fertile, organic rich topsoil. However, the varying effect of land degradation in the region on soils developed from different parent material - which may influence soil fertility and carbon stabilization - are still largely unknown. To examine these factors, we compared soil organic carbon (SOC) and soil fertility indicators in undisturbed forest topsoils with cropland hillslope topsoils along a chronosequence after deforestation (2–7, 10–20, 20–40, > 60 years of cropping, land abandonment) on mafic (South Kivu, Democratic Republic of Congo) and felsic parent material (western Uganda). From previous studies, we expected higher soil fertility and SOC contents and therefore slower degradation on mafic soils due to the higher amounts of clay and pedogenic metal phases which stabilize SOM and thus further maintain soil fertility.
However, we found similar SOC contents on both parent materials and a consistent decrease with time after deforestation. SOC values were significantly lower in soils that were cleared more than 60 years ago, compared to cropland which was cleared 2–7 years ago and nearby undisturbed forest topsoils (0–10 cm soil depth). While the effective cation exchange capacity (ECEC) positively correlated with SOC in soils on felsic parent material, this was not observed in soils with mafic parent material, where it correlated with mineralogical proxies (total reserves in bases). In both regions, SOC did not correlate with clay content. Mid-Holocene carbonate volcanism appears to have offset soil degradation in the felsic region, contributing to higher pH and ECEC and impeding land abandonment due to the maintenance of acceptable soil fertility levels. Surprisingly, abandoned cropland sites in the mafic region still had an average SOC content of 14–29 g kg-1 in topsoils, likely due to strong fixation of SOC with reactive metal phases; however, they were characterized by extremely low pH values and high Al3+ mobility, combined with low available nutrient status.
Our results emphasize that soil fertility and carbon stabilization are reliant on the mineral composition of the underlying parent material, even in deeply weathered soils of the humid tropics. Soil organic matter in degraded tropical cropland soils does not appear to be a reliable indicator of soil fertility.

description: Magma worlds, due to their hot, extended atmospheres are readily characterized spectroscopically by ground- and space-based telescopes, such as JWST. As yet, the lack of direct observations means that the nature and composition of these planets’ atmospheres are poorly constrained.  Because the atmospheres of these planets are thought to be the result of chemical equilibrium with their interiors, their mass and composition are modulated by the solubilities of major gases in the magma. Therefore, we require a theoretical framework, informed by experimental data, to determine how volatile elements partition between the interior and atmosphere for diverse planetary compositions. Of the major gases, hydrogen is particularly important due to its cosmic abundance, significant presence during rocky planet formation if the planet forms before the nebular gas disk dissipates, and its role as an essential life-forming element. However, there is currently a lack of experimental data on hydrogen solubilities in diverse planetary magmas at the temperature, pressure and redox conditions relevant for magma worlds. To fill this gap, we performed new hydrogen solubility experiments on exoplanet melt analog materials at high temperatures (≥1400 ℃) using a 1-bar H2-CO2 gas-mixing furnace and an aerodynamic laser levitation furnace coupled to an FTIR spectrometer. Using FTIR spectroscopy, we determine the mechanism for hydrogen’s dissolution and its concentrations in these melts. We will present the findings of our experiments and how we can incorporate them into volatile partitioning models to determine the effect of hydrogen solubility on the atmospheric compositions of magma exoplanets. We will discuss the implications of volatile dissolution on the interior-atmosphere connection for magma planets including the early Earth.

description: On the basis of the first law of black hole thermodynamics, we propose the concept of effective temperature of de Sitter (dS) black holes and conjecture that the effective temperature should be the temperature of the dS black holes when the Hawking radiation temperatures of the black hole horizon and the cosmological horizon are equal. Choosing different independent variables, we can find a differential equation satisfied by the entropy of the dS black hole. It is shown that the differential equation of entropy is independent of the choice of independent variables. From the differential equation, we get the entropy of dS black hole and other effective thermodynamic quantities. We also discuss the influence of several parameters on the effective thermodynamic quantities.

description: Given the host of existing and upcoming observations of rocky (exo)planet atmospheres, a quantitative understanding of the key factors that control the nature and composition of atmospheres around these diverse worlds is needed. The speciation of major atmosphere-forming components around molten rocky planets, both within and beyond the solar system, is dictated by their abundances, the equilibrium chemistry between gas species, and their solubilities in the rocky interior. Moreover, as pressure increases at the atmosphere-interior interface, the thermodynamic behaviour of the gas phase diverges from that of the ideal case. Here, we combine these considerations into a new Python package, atmodeller, which is a flexible tool kit for computing the equilibrium conditions at the melt-atmosphere interface. Given a set of planetary parameters (e.g., surface temperature, planetary mass, radius, mantle melt fraction) and an initial volatile budget, atmodeller uses experimentally calibrated solubility laws, together with free energy data for gas species, to determine how volatiles partition between the atmosphere and interior of the planet. This package can be applied widely to rocky planets, from super-Earths to sub-Neptunes with gaseous envelopes. Within the H-C-N-O-S-Cl system, we investigate the diverse range of atmospheric compositions and the impact of volatile dissolution into the interior for a set of known rocky exoplanets (e.g., the TRAPPIST-1 system) based on the current observational constraints from JWST. In addition, we use atmodeller to simulate the effects of volatile solubilities and non-ideal conditions on H2-dominated super-Earth- and sub-Neptune atmospheres (in the H-O-Si system), such as that of the recently observed exoplanet K2-18 b. Atmodeller is a new tool to study rocky (exo)planets, uniquely incorporating equilibrium chemistry, volatile solubilities and gas non-ideality to establish the connection between rocky planet interiors and their atmospheres.

description: There are rare occurrences on Earth where mantle plumes intersect with continents, resulting in surface volcanism.Unlike their more common counterparts in oceanic lithosphere, where the ascent of melts is facilitated by a thinner lithosphere, identifying continental plumes is challenging. Surface volcanism, traditionally a key indicator of mantle plumes, may play a diminished role in regions characterized by complex tectonics and variations in lithospheric thickness.

Eastern Oman provides an excellent example where a continental mantle plume has remained undetected due to the absence of current surface volcanism. The region exhibits evidence of intraplate basanites, although with an age of ~35-40 Ma. Given their geochemical signature, these alkaline rocks likely originated from a mixture of melts from a plume-derived source and those from a lithosphere-derived component. Using P- and S-wave arrival-time residuals from distant earthquakes, we image a new mantle plume in eastern Oman, which we name the Salma plume. This continental plume is revealed in our 3-D P- and S-wave tomographic models as a 200 km low-velocity conduit extending to at least the base of the upper mantle, and located below the area of Tertiary intraplate volcanism. Despite experiencing minimal shortening since the Paleogene, the shallow-marine sediments of the Salma Plateau in eastern Oman reach elevations exceeding 2000 meters. Ongoing uplift, indicated by elevated Quaternary marine terraces, suggests that the plateau is still rising. The present uplift rate is modest but maps of residual topography show a positive trend in eastern Oman that can be associated to the presence of a plume.

Incorporating a geodynamic perspective, our analysis of noise-mitigated Indian plate motion relative to Somalia reveals that India underwent a constant-velocity reorientation of approximately 15˚  from 48 to 30 Ma, concurrent with the arrival of the plume head beneath eastern Oman. We quantitatively demonstrate that increased asthenospheric flow induced by the plume flux in eastern Oman, adjacent to the Indian plate in the Eocene, may be responsible for deflecting the Indian plate path, as indicated in kinematic reconstructions.

The consequence of ignoring a plume in Oman is that we were unable to understand many of the enigmatic observations from plume impingement at ~40 Ma. Our study underscores the potential of combining seismology, geology, geochemistry, and geodynamics to be a more effective approach for detecting continental plumes than relying solely on surface volcanism, and has transformed our understanding of the tectonic evolution of the area and beyond.

description: Auroral records found in historical archives and cosmogenic isotopes found in natural archives have served as sound proxies of coronal mass ejections (CMEs) and solar energetic particles (SEPs), respectively, for dates prior to the onset of telescopic sunspot observations in 1610. These space weather events constitute a significant threat to a modern civilization, because of its increasing dependency on an electronic infrastructure. Recent studies have identified multiple extreme space weather events derived from solar energetic particles (SEPs) in natural archives, such as the event in 660 BCE. While the level of solar activity around 660 BCE is of great interest, this had not been within the coverage of the hitherto-known datable auroral records in historical documents that extend back to the 6th century BCE. Therefore, we have examined Assyrian astrological reports in the 8th and 7th centuries BCE, identified three observational reports of candidate aurorae, and dated these reports to approximately 680 BCE -- 650 BCE. The Assyrian cuneiform tablets let us extend the history of auroral records and solar activity by a century. These cuneiform reports are considered to be the earliest datable records of candidate aurorae and they support the concept of enhanced solar activity suggested by the cosmogenic isotopes from natural archives.

description: Time projection chambers (TPCs) are widely used in nuclear and particle physics. They are particularly useful when measuring reaction products from heavy ion collisions. Most nuclear experiments at low energy are performed in a fixed target configuration, in which the unreacted beam will pass through the detection volume. As the beam intensity increases, the buildup of positive ions created from the ionization of the detector gas by the beam creates the main source of space charge, distorting the nominal electric field of the TPC. This has a profound effect on the accuracy of the measured momenta of the emitted particles. In this paper we will discuss the magnitude of the effects and construct an observable more appropriate for fixed target experiments to study the effects. We also will present an algorithm for correcting the space charge and some of the implications it has on the momentum determination.
