RHIC SPIN FLIPPER COMMISSIONING.

An ac dipole with horizontally oriented oscillating magnetic field (spin flipper) was installed in FU-IIC to reverse the spin direction in the presence of two full Siberian snakes, thereby reducing the systematic errors for the spin physics experiments in RHIC. With two full snakes, the spin vector completes one full precession around the vertical direction in two revolutions, and the spin depolarization resonances due to the machine imperfections and betatron oscillations are eliminated. Since the spin flipper provides an oscillating horizontal dipole field, a ''spin resonance'' can occur if the spin flipper frequency is placed in the neighborhood of the spin precession frequency [ 1,2,3]. By slowly sweeping the spin flipper frequency across the spin precession frequency, a full spin flip can be achieved. This paper reports the results of the FZUC spin flipper commissioned during the RHIC 2002 polarized proton run. By running the spin flipper at a slightly different configuration, one can also measure the spin precession tune.
Sensitivity of land-surface variables to scale in identifying landslide scarps

Geomorphological features, in general, and landslides, in particular, come on different sizes and shapes. However, the landsurface variables (LSVs) that are used to describe them are often employed at a unique scale, as resulted from derivation in a standard 3×3 moving window. In this paper we test the hypothesis that identification of landslide scarps improves when individual LSVs are calibrated to scale. For this purpose, we set up an experimental design, which was run in two topographically different locations: Shizuoka Prefecture, Japan and Buzau County, Romania. The experiment includes two steps: i) finding the scale at which each LSV achieves the best prediction of the scarps, and ii) comparing the modeling results of the scaled LSVs against LSVs at the default scale. In the first step, each LSV is up-scaled using focal mean statistics in a steadily increasing moving window, which starts at 3×3 and grows until the respective LSV achieves the maximum degree of fitting with the scarps. The degree of fitting is determined with logistic regression. In the second step, the LSVs at the calibrated scales are used as the input data for a random forest (RF) model. The RF model was ran with the same settings on the default LSVs (i.e. derived in a 3×3 window) as well, for comparison. The results show a consistent increase in the AUC score when LSVs where calibrated to scale, as compared to the modeling with the default LSVs, from 80.31 to 91.54 in the first study area, and from 74.62 to 83.11 in the second one. The results also show that each predictor operates at its specific scale; therefore a single ‘optimal’ scale does not apply for all LSVs.
NEAR-IR IMAGING POLARIMETRY TOWARD A BRIGHT-RIMMED CLOUD: MAGNETIC FIELD IN SFO 74

We have made near-infrared (JHKs) imaging polarimetry of a bright-rimmed cloud (SFO 74). The polarization vector maps clearly show that the magnetic field in the layer just behind the bright rim is running along the rim, quite different from its ambient magnetic field. The direction of the magnetic field just behind the tip rim is almost perpendicular to that of the incident UV radiation, and the magnetic field configuration appears to be symmetric as a whole with respect to the cloud symmetry axis. We estimated the column and number densities in the two regions (just inside and far inside the tip rim) and then derived the magnetic field strength, applying the Chandrasekhar–Fermi method. The estimated magnetic field strength just inside the tip rim, ∼90 μG, is stronger than that far inside, ∼30 μG. This suggests that the magnetic field strength just inside the tip rim is enhanced by the UV-radiation-induced shock. The shock increases the density within the top layer around the tip and thus increases the strength of the magnetic field. The magnetic pressure seems to be comparable to the turbulent one just inside the tip rim, implying a significant contribution of the magnetic field to the total internal pressure. The mass-to-flux ratio was estimated to be close to the critical value just inside the tip rim. We speculate that the flat-topped bright rim of SFO 74 could be formed by the magnetic field effect.

Publication Rights Licensed to ACM. Abstract Large-scale immersive environments can convey a large amount of information to many participants simultaneously. When equipped with occupant-awareness, not only does the ability of the participants to interact with the environment increase dramatically, but also the environment’s understanding of its audience. Using ceiling-mounted timeof-flight distance sensors, we discuss how person tracking, body orientation estimation, and pointing gesture recognition can augment an immersive environment to become simultaneously aware of all its participants. The testbed for our exploration is a large circular space 12 m in diameter enclosed by a 360 degree display 4.3 meters high, which can comfortably house more than 30 people at a time. This large-scale occupant-aware immersive environment is an ideal space to simulate different “living lab” scenarios or conduct group behavioral studies.
Mining Sequential Patterns Using I-PrefixSpan

— In this paper, we propose an improvement of pattern growth-based PrefixSpan algorithm, called I-PrefixSpan. The general idea of I-PrefixSpan is to use sufficient data structure for Seq-Tree framework and separator database to reduce the execution time and memory usage. Thus, with I-PrefixSpan there is no in-memory database stored after index set is constructed. The experimental result shows that using Java 2, this method improves the speed of PrefixSpan up to almost two orders of magnitude as well as the memory usage to more than one order of magnitude.
Multigrid Methods for Nearly Singular Linear Equations and Eigenvalue Problems

The purpose of this paper is to develop a convergence theory for multigrid methods applied to nearly singular linear elliptic partial differential equations of the type produced from a positive definite system by a shift with the identity. One of the important aspects of this theory is that it allows such shifts to vary anywhere in the multigrid scheme, enabling its application to a wider class of eigenproblem solvers. The theory is first applied to a method for computing eigenvalues and eigenvectors that consists of multigrid iterations with zero right-hand side and updating the shift from the Rayleigh quotient before every cycle. It is then applied to the Rayleigh quotient multigrid (RQMG) method, which is a more direct multigrid procedure for solving eigenproblems. Local convergence of the multigrid V-cycle and global convergence for a full multigrid version of both methods is obtained.
Semi-metallic, strong and stretchable wet-spun conjugated polymer microfibers

A dramatic improvement in electrical conductivity is necessary to make conductive polymer fibers viable candidates in applications such as flexible electrodes, conductive textiles, and fast-response sensors and actuators. In this study, high-performance poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT/PSS) conjugated polymer microfibers were fabricated via wet-spinning followed by hot-drawing. Due to the combined effects of the vertical hot-drawing process and doping/de-doping the microfibers with ethylene glycol (EG), we achieved a record electrical conductivity of 2804 S cm−1. This is, to the best of our knowledge, a six-fold improvement over the best previously reported value for PEDOT/PSS fibers (467 S cm−1) and a two-fold improvement over the best values for conductive polymer films treated by EG de-doping (1418 S cm−1). Moreover, we found that these highly conductive fibers experience a semiconductor–metal transition at 313 K. They also have superior mechanical properties with a Young's modulus up to 8.3 GPa, a tensile strength reaching 409.8 MPa and a large elongation before failure (21%). The most conductive fiber also demonstrates an extraordinary electrical performance during stretching/unstretching: the conductivity increased by 25% before the fiber rupture point with a maximum strain up to 21%. Simple fabrication of the semi-metallic, strong and stretchable wet-spun PEDOT/PSS microfibers described here could make them available for conductive smart electronics.

Fall Conference 2015 – College of Veterinary Medicine at Urbana-Champaign Strategies to Improve Reproductive Performance in Cattle

Introduction The decline in fertility reported from 1960 to early 2000’s (Lucy, 2001) was the motive for prolific research in dairy cows, which in instance lead to identification of multiple culprit factors for this impaired reproductive performance in dairy cattle. (Norman et al., 2009; Santos et al., 2004). Reduced fertilization, embryonic survival, and high prevalence of anovulation in dairy cows compromising detection of estrus, pregnancy per AI and maintenance of pregnancy were defined as the major factors responsible for impaired reproductive performance in dairy cattle (Santos et al., 2004; Santos et al., 2010a). Extensive use of timed AI started with the development of OvSynch program (Pursley et al., 1995), the implementation of daughter pregnancy rate (DPR), the phenotypic measure used by the USDA for daughter fertility (Norman et al., 2009), and use of production life in selection program halted the decline in reproductive performance of dairy cows reported for the previous 40 years. However, DPR is influenced by voluntary waiting period and breeding policy at the farm level, thus it is unclear how much of this improvement is a true function of better fertility, or just implementation of better reproductive management. Herein, reproductive management strategies that empower veterinarians with tools to help dairy producers improve fertility will be discussed with emphasis on its implementation. Although data presented on this manuscript is from dairy cattle, there are many physiological responses and strategies that can be applied to beef cows. I will present some examples to illustrate scenarios for beef cattle during my seminar at the fall conference.
Elemental, isotopic, and structural changes in Tagish Lake insoluble organic matter produced by parent body processes

Here, we present the results of a multitechnique study of the bulk properties of insoluble organic material (IOM) from the Tagish Lake meteorite, including four lithologies that have undergone different degrees of aqueous alteration. The IOM C contents of all four lithologies are very uniform and comprise about half the bulk C and N contents of the lithologies. However, the bulk IOM elemental and isotopic compositions vary significantly. In particular, there is a correlated decrease in bulk IOM H/C ratios and δD values with increasing degree of alteration—the IOM in the least altered lithology is intermediate between CM and CR IOM, while that in the more altered lithologies resembles the very aromatic IOM in mildly metamorphosed CV and CO chondrites, and heated CMs. Nuclear magnetic resonance (NMR) spectroscopy, C X‐ray absorption near‐edge (XANES), and Fourier transform infrared (FTIR) spectroscopy confirm and quantitate this transformation from CR‐like, relatively aliphatic IOM functional group chemistry to a highly aromatic one. The transformation is almost certainly thermally driven, and probably occurred under hydrothermal conditions. The lack of a paramagnetic shift in 13C NMR spectra and 1s‐σ* exciton in the C‐XANES spectra, both typically seen in metamorphosed chondrites, shows that the temperatures were lower and/or the timescales were shorter than experienced by even the least metamorphosed type 3 chondrites. Two endmember models were considered to quantitatively account for the changes in IOM functional group chemistry, but the one in which the transformations involved quantitative conversion of aliphatic material to aromatic material was the more successful. It seems likely that similar processes were involved in producing the diversity of IOM compositions and functional group chemistries among CR, CM, and CI chondrites. If correct, CRs experienced the lowest temperatures, while CM and CI chondrites experienced similar more elevated temperatures. This ordering is inconsistent with alteration temperatures based on mineralogy and O isotopes.
Rate and apparent quantum yield of photodissolution of sedimentary organic matter

We quantified rates of photochemical dissolution (photodissolution) of organic carbon in coastal Louisiana suspended sediments, conducting experiments under well‐defined conditions of irradiance and temperature. Optical properties of the suspended sediments were characterized and used in a radiative transfer model to compute irradiances within turbid suspensions. Photodissolution rate increased with temperature (T), with activation energy of 32 ± 7 kJ mol−1, which implicates indirect (non‐photochemical) steps in the net reaction. In most samples, dissolved organic carbon (DOC) concentration increased approximately linearly with time over the first 4 h of irradiation under broadband simulated sunlight, after higher rates in the initial hour of irradiation. Four‐hour rates ranged from 2.3 µmol DOC m−3 s−1 to 3.2 µmol DOC m−3 s−1, but showed no relation to sample origin within the study area, organic carbon or reducible iron content, or mass‐specific absorption coefficient. First‐hour rates were higher—from 3.5 µmol DOC m−3 s−1 to 7.8 µmol DOC m−3 s−1—and correlated well with sediment reducible iron (itself often associated with organic matter). The spectral apparent quantum yield (AQY) for photodissolution was computed by fitting DOC photoproduction rates under different spectral irradiance distributions to corresponding rates of light absorption by particles. The photodissolution AQY magnitude is similar to most published dissolved‐phase AQY spectra for dissolved inorganic carbon photoproduction, which suggests that in turbid coastal waters where particles dominate light absorption, DOC photoproduction from particles exceeds photooxidation of DOC.
PHANTOM , GHOSTDAG : Two Scalable BlockDAG protocols

In 2008 Satoshi Nakamoto invented the basis for blockchain based distributed ledgers. The core concept of this system is an open and anonymous network of nodes, or miners, which together maintain a public ledger of transactions. The ledger takes the form of a chain of blocks, the blockchain, where each block is a batch of new transactions collected from users. One primary problem with Satoshi’s blockchain is its highly limited scalability. The security of Satoshi’s longest chain rule, more generally known as the Bitcoin protocol, requires that all honest nodes be aware of each other’s blocks very soon after the block’s creation. To this end, the throughput of the system is artificially suppressed so that each block fully propagates before the next one is created, and that very few “orphan blocks” that fork the chain be created spontaneously. In this paper we present PHANTOM, a PoW based protocol for a permissionless ledger that generalizes Nakamoto’s blockchain to a direct acyclic graph of blocks (blockDAG). PHANTOM includes a parameter k that controls the level of tolerance of the protocol to blocks that were created concurrently, which can be set to accommodate higher throughput. It thus avoids the security-scalability tradeoff which Satoshi’s protocol suffers from. PHANTOM uses a greedy algorithm on the blockDAG to distinguish between blocks mined properly by honest nodes and those that created by non-cooperating nodes who chose to deviate from the mining protocol. Using this distinction, PHANTOM provides a robust total order on the blockDAG in a way that is eventually agreed upon by all honest nodes.
AN INTEGRATED WASTE ASSAY SYSTEM USING TOMOGRAPHIC AND SEGMENTED GAMMA SCANNING FOR NUCLEAR POWER PLANT APPLICATIONS -10375

An integrated system was built and tested for the non-destructive assay of drummed radioactive waste from nuclear power plants. The system is intended for assaying waste items of contact dose rates over a wide dynamic range with a maximum of 200 R/hr. The system is capable of assaying 208 liter drums (55 U.S. Gallons) and 320 liter (85 U.S. Gallons) over-pack drums in two different modes; a Tomographic Gamma Scanning (TGS) mode and a Segmented Gamma Scanning (SGS) mode. The assay geometry for a given item is configured by automatically adjusting a variable aperture collimator, the distance of the detector from the drum, and the usage of lead attenuators of three different thicknesses. The geometry adjustment is chosen based on the measured dose rate of the item. A 15 milli-Curie Eu-152 transmission source is used in the system to determine matrix attenuation. Waste items with matrix densities between 0 and 1 g/cc were assayed in the TGS mode. TGS combines High Resolution Gamma Spectrometry (HRGS) with low spatial resolution image reconstruction to yield matrix attenuation compensated assay results. In a TGS assay, the item is scanned in 3-degrees of freedom; rotation, translation and elevation. Matrix attenuation and radionuclide concentration are obtained on a ~50 mm voxel by voxel basis. Therefore, the TGS technique is well suited for assaying non-uniform distributions of radionuclides in non-homogeneous matrices. The SGS mode can be used to increase throughput at low densities but also extends the density range to circa 3.0 g/cc by relying on simplified assumptions when the quality of the transmission data deteriorates. One of the distinguishing features of the current system is that the TGS scan was done in a direction opposite to the scans performed by other Canberra systems in the field. The unique scan direction was necessitated because of site specific requirements for installing the system. The site installation also required data acquisition to be collected via Ethernet through the Canberra Lynx instead of the AccuspecB used on other Canberra systems. In this work, we discuss the performance characteristics of the TGS system and show results of image reconstructions of point sources placed in known voxel locations. The efficiency calibration in the SGS mode was performed using Canberra’s In Situ Object Calibration Software (ISOCS). ISOCS, which uses mathematical ray-tracing techniques to determine gamma ray full energy peak efficiencies. This paper presents also the system performance in the SGS mode.

A Compactness Theorem for the Yamabe Problem

In this paper we prove compactness for the full set of solutions to the Yamabe Problem, if n ≤ 24. After proving sharp pointwise estimates at a blowup point, we prove the Weyl Vanishing Theorem in those dimensions, and reduce the compactness question to showing positivity of a quadratic form. We also show that this quadratic form has negative eigenvalues, if n ≥ 25.
Reliability and Evaluation of Identification Models Exemplified by a Histological Diagnosis Model

Expert systems, or more precise decision support systems, are valuable tools for structuring the results of scientific research and to translate this to knowledge. The decision support sys‐ tem Determinator is now used for several years as a platform for models to identify subjects [1, 2]. The system is based on the two main different procedures for identification [3, 4]; a sin‐ gle access key (tree) and a free access key (matrix). The latter option provides the possibility to calculate the match between the subject as chosen by the user and the objects as included in the data model, based on a range of characteristics. In addition, a matrix allows to make selections, to filter the set of available objects and to compare two objects for their variability.
