Reactions on certain proton-rich, radioactive nuclei have been shown to have a significant influence on X-ray bursts. We provide an overview of two recent measurements of important X-ray burst reactions using in-flight radioactive ion beams from the RESOLUT facility at the J. D. Fox Superconducting Accelerator Laboratory at Florida State University. The 17F(d,n)18Ne reaction was measured, and Asymptotic Normalization Coefficients were extracted for bound states in 18Ne that determine the direct-capture cross section dominating the 17F(p,γ)18Ne reaction rate for T ≲ 0.45 GK. Unbound resonant states were also studied, and the single-particle strength for the 4.523-MeV (3+) state was found …

Money Over Marriage: Marriage Importance As A Mediator Between Materialism And Marital Satisfaction, Ashley B. Lebaron, Heather H. Kelley, Jason S. Carroll Dec 2017

Money Over Marriage: Marriage Importance As A Mediator Between Materialism And Marital Satisfaction, Ashley B. Lebaron, Heather H. Kelley, Jason S. Carroll

Faculty Publications

While the negative relationship between materialism and marital satisfaction is well documented, mediators that possibly explain this association have not been widely explored. Based on the Incompatibility of Materialism and Children Model and Marital Paradigms Theory, this article explores the perception of marriage importance as a potential mediator between materialism and marital satisfaction. Using a sample of 1310 married individuals, we found evidence of partial mediation in that materialism was negatively associated with perception of marriage importance, and this association partially explained why being materialistic was associated with lower marital satisfaction. Thus, as counselors, therapists, and financial planners work with …

The present study used in a person-centered approach to examine heterogeneity in children's patterns of routine disclosure (i.e., sharing information regarding their whereabouts and activities to parents) across adolescence and explored predictors and outcomes of different trajectories. Participants included 500 adolescents (51% female, 67% White, 33% single-parent families) who completed questionnaires every year from age 12 to age 18. Growth mixture modeling suggested that the majority of adolescents (82%) reported low and stable disclosure, and a third party (5%) a steep decrease and leveling out over time. Group membership varied as a function of predictors at age 12 (delinquency, prosocial …

During the past several decades, the Earth system has changed significantly, especially across Northern Eurasia. Changes in the socio-economic conditions of the larger countries in the region have also resulted in a variety of regional environmental changes that can have global consequences. The Northern Eurasia Future Initiative (NEFI) has been designed as an essential continuation of the Northern Eurasia Earth Science Partnership Initiative (NEESPI), which was launched in 2004. NEESPI sought to elucidate all aspects of ongoing environmental change, to inform societies and, thus, to better prepare societies for future developments. A key principle of NEFI is that these developments …

Perchlorate-Coupled Carbon Monoxide (Co) Oxidation: Evidence For A Plausible Microbe-Mediated Reaction In Martian Brines, Marisa R. Myers, Gary M. King Dec 2017

Perchlorate-Coupled Carbon Monoxide (Co) Oxidation: Evidence For A Plausible Microbe-Mediated Reaction In Martian Brines, Marisa R. Myers, Gary M. King

Faculty Publications

© 2017 Myers and King. The presence of hydrated salts on Mars indicates that some regions of its surface might be habitable if suitable metabolizable substrates are available. However, several lines of evidence have shown that Mars' regolith contains only trace levels of the organic matter needed to support heterotrophic microbes. Due to the scarcity of organic carbon, carbon monoxide (CO) at a concentration of about 700 parts per million (about 0.4 Pa) might be the single most abundant readily available substrate that could support near-surface bacterial activity. Although a variety of electron acceptors can be coupled to CO oxidation, …

Are The Stock Markets “Rigged”? An Empirical Analysis Of Regulatory Change, Stephen F. Diamond, Jennifer W. Kuan Dec 2017

Are The Stock Markets “Rigged”? An Empirical Analysis Of Regulatory Change, Stephen F. Diamond, Jennifer W. Kuan

Faculty Publications

Volatile events in the stock market such as the 2010 Flash Crash have sparked concern that financial markets are “rigged” in favor of trading firms that use high frequency trading (“HFT”) systems. We analyze a regulatory change implemented by the SEC in 2007 by examining its effect on a key market metric, the bid-ask spread, an investor cost, and find that the regulatory shift, indeed, disadvantages investors. We link the implementation of this change to a shift in the volume of trades from a low-cost venue to a high-cost venue. We argue that this outcome is predicted by the incentives …

Measurements of hadron production in the TeV energy range are one of the tasks of the future studies at the Large Hadron Collider (LHC). The main goal of these experiments is a study of the fundamental QCD processes at this energy range, which is very important not only for probing of the Standard Model but also for ultrahigh-energy cosmic particle physics. One of the key elements of these experiments measurements are hadron identification. The only detector technology which has a potential ability to separate hadrons in this energy range is Transition Radiation Detector (TRD) technology. TRD prototype based on straw …

In recent years, developments of gaseous detectors based on a combination of electron multiplication gap in the gas and pixel readout chips as a part of the anode plane (GasPixel detectors) reached a level where they can offer unique opportunities for particle detection. Transition radiation (TR) detectors based on this technology can be one of the possible applications. In this work, measurements of energy spectra and angular distributions of transition radiation photons produced by particles with different gamma factors made with a GridPix detector prototype are presented. The observed results are compared with theoretical predictions.

On 2017 June 8 at 02:01:16.49 UTC, a gravitational-wave (GW) signal from the merger of two stellar-mass blackholes was observed by the two Advanced Laser Interferometer Gravitational-Wave Observatory detectors with anetwork signal-to-noise ratio of 13. This system is the lightest black hole binary so far observed, with componentmasses of 12+7-2M⊙7+2-2 (90% credible intervals). These lie in the range of measured black hole masses inlow-mass X-ray binaries, thus allowing us to compare black holes detected through GWs with electromagneticobservations. The source's luminosity distance is 340+140-140corresponding to redshift -0.07+0.03003. We verify thatthe signal waveform is consistent with the predictions of general relativity.

Upper Bounds On Secret-Key Agreement Over Lossy Thermal Bosonic Channels, Eneet Kaur, Mark M. Wilde Dec 2017

Upper Bounds On Secret-Key Agreement Over Lossy Thermal Bosonic Channels, Eneet Kaur, Mark M. Wilde

Faculty Publications

Upper bounds on the secret-key-agreement capacity of a quantum channel serve as a way to assess the performance of practical quantum-key-distribution protocols conducted over that channel. In particular, if a protocol employs a quantum repeater, achieving secret-key rates exceeding these upper bounds is evidence of having a working quantum repeater. In this paper, we extend a recent advance [Liuzzo-Scorpo, Phys. Rev. Lett. 119, 120503 (2017)PRLTAO0031-900710.1103/PhysRevLett.119.120503] in the theory of the teleportation simulation of single-mode phase-insensitive Gaussian channels such that it now applies to the relative entropy of entanglement measure. As a consequence of this extension, we find tighter upper bounds …

By using magnetization and small-angle neutron scattering measurements, we have investigated the magnetic behavior of the Mn1-xIrxSi system to explore the effect of increased carrier density and spin-orbit interaction on the magnetic properties of MnSi. We determine estimates of the spin wave stiffness and the Dzyaloshinskii-Moriya (DM) interaction strength and compare with Mn1-xCoxSi and Mn1-xFexSi. Despite the large differences in atomic mass and size of the substituted elements, Mn1-xCoxSi and Mn1-xIrxSi show nearly identical variations in their magnetic properties with substitution. We find a systematic dependence of the transition temperature, the ordered moment, the helix period, and the DM interaction …

Orientation Dependence Of Temporal And Spectral Properties Of High-Order Harmonics In Solids, Mengxi Wu, Yongsing You, Shambhu Ghimire, David A. Reis, Dana A. Browne, Kenneth J. Schafer, Mette B. Gaarde

Faculty Publications

We investigate the connection between crystal symmetry and temporal and spectral properties of high-order harmonics in solids. We calculate the orientation-dependent harmonic spectrum driven by an intense, linearly polarized infrared laser field, using a momentum-space description of the generation process in terms of strong-field-driven electron dynamics on the band structure. We show that the orientation dependence of both the spectral yield and the subcycle time profile of the harmonic radiation can be understood in terms of the coupling strengths and relative curvatures of the valence band and the low-lying conduction bands. In particular, we show that in some systems this …

Alcohol Priming And Attribution Of Blame In An Acquaintance Rape Vignette, Elena V. Stepanova, Amy L. Brown Dec 2017

Alcohol Priming And Attribution Of Blame In An Acquaintance Rape Vignette, Elena V. Stepanova, Amy L. Brown

Faculty Publications

Research on nonpharmacological effects of alcohol shows that exposure to alcohol-related cues (i.e., alcohol priming) can increase behaviors associated with actual alcohol consumption. Attributions of responsibility to female victims in sexual assault scenarios are affected by whether or not alcohol was consumed by a victim and/or perpetrator. Victims often receive higher levels of blame if they consume alcohol prior to the assault. This work extends the research on nonpharmacological effects of alcohol into a novel domain of blame attribution toward rape victims. In two studies, participants in lab settings (Study 1; N = 184) and online (Study 2; N = …

Material State Awareness For Composites Part Ii: Precursor Damage Analysis And Quantification Of Degraded Material Properties Using Quantitative Ultrasonic Image Correlation (Quic), Subir Patra, Sourav Banerjee

Faculty Publications

Material state awareness of composites using conventional Nondestructive Evaluation (NDE) method is limited by finding the size and the locations of the cracks and the delamination in a composite structure. To aid the progressive failure models using the slow growth criteria, the awareness of the precursor damage state and quantification of the degraded material properties is necessary, which is challenging using the current NDE methods. To quantify the material state, a new offline NDE method is reported herein. The new method named Quantitative Ultrasonic Image Correlation (QUIC) is devised, where the concept of microcontinuum mechanics is hybrid with the experimentally …

Material State Awareness For Composites Part I: Precursor Damage Analysis Using Ultrasonic Guided Coda Wave Interferometry (Cwi), Subir Patra, Sourav Banerjee

Faculty Publications

Detection of precursor damage followed by the quantification of the degraded material properties could lead to more accurate progressive failure models for composite materials. However, such information is not readily available. In composite materials, the precursor damages—for example matrix cracking, microcracks, voids, interlaminar pre-delamination crack joining matrix cracks, fiber micro-buckling, local fiber breakage, local debonding, etc.—are insensitive to the low-frequency ultrasonic guided-wave-based online nondestructive evaluation (NDE) or Structural Health Monitoring (SHM) (~100–~500 kHz) systems. Overcoming this barrier, in this article, an online ultrasonic technique is proposed using the coda part of the guided wave signal, which is often neglected. Although …

© 2017. Published by The Company of Biologists Ltd . Social animals must constantly assess their environment to make appropriate behavioral decisions. The use of various sensory modalities is imperative in this process and it is hypothesized that the highly conserved brain nuclei comprising the social decisionmaking network (SDMN) integrates social information with an animal's internal state to elicit behavioral responses. Here, we used the highly social African cichlid fish, Astatotilapia burtoni, to investigate whether reproductively receptive (gravid) females show contextual chemosensory signaling, social behaviors and neural activation patterns within the SDMN. We exposed gravid females to different social contexts: …

We present a new method for probing the hadronic interaction models at ultrahigh energy and extracting details about mass composition. This is done using the time profiles of the signals recorded with the water-Cherenkov detectors of the Pierre Auger Observatory. The profiles arise from a mix of the muon and electromagnetic components of air showers. Using the risetimes of the recorded signals, we define a new parameter, which we use to compare our observations with predictions from simulations. We find, first, inconsistencies between our data and predictions over a greater energy range and with substantially more events than in previous …

© 2017 American Chemical Society. Many bacteria encode biosynthetic proteins that produce a vast array of natural products. These compounds are often synthesized during host invasion as they function as virulence factors. In addition, such secondary metabolites have yielded numerous molecular scaffolds with pharmaceutical and clinical importance. The gene clusters that encode proteins responsible for synthesis of these compounds are typically silenced or "cryptic" under laboratory growth conditions, hampering discovery of novel lead compounds. We report here that MftR is a global repressor of secondary metabolite synthesis in Burkholderia thailandensis and that urate functions as a physiologically relevant inducer of …

Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of continuous gravitational waves for ground-based interferometric detectors. In the case of known pulsars a fully coherent search, based on matched filtering, which uses the position and rotational parameters obtained from electromagnetic observations, can be carried out. Matched filtering maximizes the signal-to-noise (SNR) ratio, but a large sensitivity loss is expected in case of even a very small mismatch between the assumed and the true signal parameters. For this reason, narrow-band analysis methods have been developed, allowing a fully coherent search for gravitational waves from known pulsars …

We report results of a deep all-sky search for periodic gravitational waves from isolated neutron stars in data from the first Advanced LIGO observing run. This search investigates the low frequency range of Advanced LIGO data, between 20 and 100 Hz, much of which was not explored in initial LIGO. The search was made possible by the computing power provided by the volunteers of the Einstein@Home project. We find no significant signal candidate and set the most stringent upper limits to date on the amplitude of gravitational wave signals from the target population, corresponding to a sensitivity depth of 48.7 …
