Quantum information transfer for qutrits

We propose a scheme for the transfer of quantum information among distant qutrits. We apply this scheme to the distribution of entanglement among distant nodes and to the generation of multipartite antisymmetric states. We also discuss applications to quantum secret sharing

Unforeseen crystal forms of the natural osmolyte floridoside

Floridoside (2-α-O-D-galactopyranosyl glycerol) is a glycerol glycoside that is biosynthesised by most species of red algae and has been implicated as an intracellular regulator of various homeostatic functions. Here, we report the identification of two unforeseen crystal forms of the ubiquitous natural osmolyte floridoside including a seemingly unheralded second anhydrous conformational polymorph and the unambiguous description of an elusive monohydrated variant. By employing a variety of thermal and spectroscopic techniques, we begin to explore both their macro and molecular physicochemical properties, which are notably different to that of the previously reported polymorph. This work advances the characterisation of this important natural biomolecule which could aid in facilitating optimised utilisation across a variety of anthropocentric applications and improve comprehension of its role in-vivo as a preeminent compatible solute

INTRODUCTION The theme for the Lectures for 1934, “The New Testament Church in History,” is a very timely one and follows naturally the theme of the 1933 Lectures, “The Church We Read About in the New Testament.” There is no subject that is so vital in our work as Christians today as a proper understanding of the great spiritual kingdom of our Savior, the church which was built by Jesus Christ. It is a hard lesson to teach because all people are so dull of hearing concerning things spiritual. Just as Nicodemus marveled when the Christ told him of the spiritual kingdom so do people today wonder and marvel when they are told that there is only one great church, the spiritual kingdom of our Lord and Savior Jesus Christ, and that all the saved of earth belong to that church and that belonging to anything else profits little, and is unnecessary. Not only are numbers of denominational churches and people who have no religious affiliation ignorant of the true meaning of the church, but even those who claim to be members of the one body are lacking in understanding concerning the kingdom of Christ. It is therefore the purpose of the Abilene College Lectures last year, this year and next year to arouse a greater interest in the study and the teaching of this very vital matter. In this particular volume much valuable information is brought together on the trials and struggles of the church from its foundations to the present. The speakers have made careful preparation on their subjects and have given lessons that should prove helpful to all who desire to have a better understanding of the church. Our prayer is that these Lectures may be read by many and that they may do much good in the name of the Christ. Jas. F. Cox,President, Abilene Christian College. Nov. 6, 1934

The Radio Sky at Meter Wavelengths: m-Mode Analysis Imaging with the Owens Valley Long Wavelength Array

A host of new low-frequency radio telescopes seek to measure the 21-cm transition of neutral hydrogen from the early universe. These telescopes have the potential to directly probe star and galaxy formation at redshifts $20 \gtrsim z \gtrsim 7$, but are limited by the dynamic range they can achieve against foreground sources of low-frequency radio emission. Consequently, there is a growing demand for modern, high-fidelity maps of the sky at frequencies below 200 MHz for use in foreground modeling and removal. We describe a new widefield imaging technique for drift-scanning interferometers, Tikhonov-regularized $m$-mode analysis imaging. This technique constructs images of the entire sky in a single synthesis imaging step with exact treatment of widefield effects. We describe how the CLEAN algorithm can be adapted to deconvolve maps generated by $m$-mode analysis imaging. We demonstrate Tikhonov-regularized $m$-mode analysis imaging using the Owens Valley Long Wavelength Array (OVRO-LWA) by generating 8 new maps of the sky north of $\delta=-30^\circ$ with 15 arcmin angular resolution, at frequencies evenly spaced between 36.528 MHz and 73.152 MHz, and $\sim$800 mJy/beam thermal noise. These maps are a 10-fold improvement in angular resolution over existing full-sky maps at comparable frequencies, which have angular resolutions $\ge 2^\circ$. Each map is constructed exclusively from interferometric observations and does not represent the globally averaged sky brightness. Future improvements will incorporate total power radiometry, improved thermal noise, and improved angular resolution -- due to the planned expansion of the OVRO-LWA to 2.6 km baselines. These maps serve as a first step on the path to the use of more sophisticated foreground filters in 21-cm cosmology incorporating the measured angular and frequency structure of all foreground contaminants.Comment: 27 pages, 18 figure

A Southern Hemisphere record of global trace-metal drawdown and orbital modulation of organic-matter burial across the Cenomanian–Turonian boundary (Ocean Drilling Program Site 1138, Kerguelen Plateau)

Despite its assumed global nature, there are very few detailed stratigraphic records of the late Cenomanian to the early Turonian Oceanic Anoxic Event 2 from the Southern Hemisphere. A highly resolved record of environmental changes across the Cenomanian\u2013Turonian boundary interval is presented from Ocean Drilling Program Site 1138 on the central Kerguelen Plateau (southern Indian Ocean). The new data lead to three key observations. Firstly, detailed biostratigraphy and chemostratigraphy indicate that the record of Oceanic Anoxic Event 2 is not complete, with a hiatus spanning the onset of the event. A decrease in glauconite and highly weathered clays after the onset of Oceanic Anoxic Event 2 marks the end of the hiatus interval, which can be explained by a relative sea-level rise that increased sediment accommodation space on the Kerguelen Plateau margin. This change in depositional environment controlled the timing of the delayed peak in organic-matter burial during Oceanic Anoxic Event 2 at Site 1138 compared with other Oceanic Anoxic Event 2 locations worldwide. A second key observation is the presence of cyclic fluctuations in the quantity and composition of organic matter being buried on the central Kerguelen Plateau throughout the latter stages of Oceanic Anoxic Event 2 and the early Turonian. A close correspondence between organic matter, sedimentary elemental compositions and sediments recording sea-floor oxygenation suggests that the cycles were mainly productivity-driven phenomena. Available age-control points constrain the periodicity of the coupled changes in sedimentary parameters to ca 20 to 70 ka, suggesting a link between carbon burial and astronomically forced climatic variations (precession or obliquity) in the Southern Hemisphere mid-latitudes both during, and after, Oceanic Anoxic Event 2: fluctuations that were superimposed on the impact of global-scale processes. Finally, trace-metal data from the black-shale unit at Site 1138 provide the first evidence from outside of the proto-North Atlantic region for a global drawdown of seawater trace-metal (Mo) inventories during Oceanic Anoxic Event 2

River discharge study, Laughlin, Nevada: Colorado River model and diffusion study

A water quality modeling study of the Mohave Reach of the Lower Colorado River (from Davis Dam to the Nevada/California Stateline) was conducted to evaluate potential water quality impacts resulting from a proposed Laughlin, Nevada wastewater effluent discharge. The study included four major components: (1) review of the current regulatory framework; (2) a field data collection program to document existing water quality conditions in winter, summer, and fall; (3) development and verification of far-field and near-field (mixing zone) water quality models; and (4) application of the models to project future river quality conditions for several treatment-discharge alternatives as well as a no-discharge alternative. Water quality criteria established by Arizona and California for the Colorado River are less stringent than those established by Nevada. The State of Nevada\u27s Requirements to Maintain Existing Higher Quality for the Colorado River below Davis Dam (NAC 445.13495) are based on a strict interpretation of the Federal anti-degradation regulations, which have not yet been addressed by Arizona or California. For example, review of the Arizona and California regulatory framework showed that neither state\u27s water quality criteria would dictate phosphorus removal and only California requires dechlorination of an effluent discharge. A steady state water quality model of the Mohave Reach was developed using the EPA QUAL-2E program and verified against data from three water quality sampling programs conducted in 1987. The only direct wastewater discharge currently entering the Mohave Reach is the effluent from the River Bend wastewater treatment plant in Bullhead City, Arizona. The discharge from Bullhead City and the proposed discharge from Laughlin were the only point loadings simulated in the model. The major water user in the Reach is the Southern California Edison Mohave Generating Plant which has an average withdrawal rate of 18 cfs. A mixing zone model was also developed to estimate dilutions downstream of the proposed outfall at Laughlin, for various diffuser configurations. The model was calibrated for lateral mixing conditions in the river using data collected during a dye diffusion test (1987). It was assumed that the location of the discharge would be on the Nevada side of the River, just below the Laughlin Bridge. The study demonstrated that existing water quality in the Mohave Reach is usually in compliance with the State of Nevada and Federal regulatory requirements, and that the proposed discharge at Laughlin, with additional treatment beyond secondary, will not cause river quality to exceed these requirements for discharges up to 7 MGD. The treatment processes recommended are phosphorus removal and dechlorination. Under WP283A 1-1 868834 these conditions, adequate assimilative capacity is available for equivalent wastewater loadings from Arizona without measurably affecting compliance with water quality objectives
