An equality between entanglement and uncertainty

Heisenberg's uncertainty principle implies that if one party (Alice) prepares a system and randomly measures one of two incompatible observables, then another party (Bob) cannot perfectly predict the measurement outcomes. This implication assumes that Bob does not possess an additional system that is entangled to the measured one; indeed the seminal paper of Einstein, Podolsky and Rosen (EPR) showed that maximal entanglement allows Bob to perfectly win this guessing game. Although not in contradiction, the observations made by EPR and Heisenberg illustrate two extreme cases of the interplay between entanglement and uncertainty. On the one hand, no entanglement means that Bob's predictions must display some uncertainty. Yet on the other hand, maximal entanglement means that there is no more uncertainty at all. Here we follow an operational approach and give an exact relation - an equality - between the amount of uncertainty as measured by the guessing probability, and the amount of entanglement as measured by the recoverable entanglement fidelity. From this equality we deduce a simple criterion for witnessing bipartite entanglement and a novel entanglement monogamy equality.Comment: v2: published as "Entanglement-assisted guessing of complementary measurement outcomes", 11 pages, 1 figur

Measures of galaxy dust and gas mass with Herschel photometry and prospects for ALMA

(Abridged) Combining the deepest Herschel extragalactic surveys (PEP, GOODS-H, HerMES), and Monte Carlo mock catalogs, we explore the robustness of dust mass estimates based on modeling of broad band spectral energy distributions (SEDs) with two popular approaches: Draine & Li (2007, DL07) and a modified black body (MBB). As long as the observed SED extends to at least 160-200 micron in the rest frame, M(dust) can be recovered with a >3 sigma significance and without the occurrence of systematics. An average offset of a factor ~1.5 exists between DL07- and MBB-based dust masses, based on consistent dust properties. At the depth of the deepest Herschel surveys (in the GOODS-S field) it is possible to retrieve dust masses with a S/N>=3 for galaxies on the main sequence of star formation (MS) down to M(stars)~1e10 [M(sun)] up to z~1. At higher redshift (z<=2) the same result is achieved only for objects at the tip of the MS or lying above it. Molecular gas masses, obtained converting M(dust) through the metallicity-dependent gas-to-dust ratio delta(GDR), are consistent with those based on the scaling of depletion time, and on CO spectroscopy. Focusing on CO-detected galaxies at z>1, the delta(GDR) dependence on metallicity is consistent with the local relation. We combine far-IR Herschel data and sub-mm ALMA expected fluxes to study the advantages of a full SED coverage.Comment: Accepted for publication in Astronomy and Astrophysics.

Simultaneous Multiwavelength Observations of Magnetic Activity in Ultracool Dwarfs. IV. The Active, Young Binary NLTT 33370 AB (=2MASS J13142039+1320011)

We present multi-epoch simultaneous radio, optical, H{\alpha}, UV, and X-ray observations of the active, young, low-mass binary NLTT 33370 AB (blended spectral type M7e). This system is remarkable for its extreme levels of magnetic activity: it is the most radio-luminous ultracool dwarf (UCD) known, and here we show that it is also one of the most X-ray luminous UCDs known. We detect the system in all bands and find a complex phenomenology of both flaring and periodic variability. Analysis of the optical light curve reveals the simultaneous presence of two periodicities, 3.7859 $\pm$ 0.0001 and 3.7130 $\pm$ 0.0002 hr. While these differ by only ~2%, studies of differential rotation in the UCD regime suggest that it cannot be responsible for the two signals. The system's radio emission consists of at least three components: rapid 100% polarized flares, bright emission modulating periodically in phase with the optical emission, and an additional periodic component that appears only in the 2013 observational campaign. We interpret the last of these as a gyrosynchrotron feature associated with large-scale magnetic fields and a cool, equatorial plasma torus. However, the persistent rapid flares at all rotational phases imply that small-scale magnetic loops are also present and reconnect nearly continuously. We present an SED of the blended system spanning more than 9 orders of magnitude in wavelength. The significant magnetism present in NLTT 33370 AB will affect its fundamental parameters, with the components' radii and temperatures potentially altered by ~+20% and ~-10%, respectively. Finally, we suggest spatially resolved observations that could clarify many aspects of this system's nature.Comment: emulateapj, 22 pages, 15 figures, ApJ in press; v2: fixes low-impact error in Figure 15; v3: now in-pres

Comparison of Routine Health Screening Rates Between Two EMR Systems

An EMR, electronic medical record, system refers to the software widely adopted by medical practitioners to reduce the use of hard-copy files, and improve the documentation, storage, and retrieval of patient information. Some EMR systems can generate automatic alerts reminding providers when patients are due for certain preventive services or meet the criteria for various screening measures. Epic, one of the leading EMR systems in use today, contains this additional feature. The screening recommendations built into Epic are derived from a committee of USPSTF, U.S. Preventive Services Task Force, medical experts whose focus is to improve patient health across the nation. In September of 2021, the University of Tennessee-Family Medicine Jackson clinic switched from using the Centricity EMR to Epic EMR. The primary goal of this study was to measure whether there is any quantifiable improvement in USPSTF screening rates after implementing the Epic EMR, which contains the notifications to prevent lapses in patient care. For each EMR, 100 patients were selected at random including those greater than 44 years of age and less than 65 years of age. This study involved checking whether patients were up-to-date on thirteen potential USPSTF screening measures and recording the data in the SPSS statistical software program. Chi-square analysis comparing the data across both Centricity and Epic, revealed no statistical significance between screening rates. However, when accounting for sex (male vs. female) across both EMRs, women in the study had 16% more drug screening, 3% more tobacco screening, and 18% more statin use in comparison to men. Furthermore, statistical significance was found when comparing race (black vs. white). For example, black patients had 10% more syphilis screening and 33% more STD screening, whereas white patients had 28% more lung cancer screening across both EMR systems. Although reassuring to find no statistical significance when comparing screening rates across both EMRs, conclusions to explain the results for specific screening measures pertaining to race and sex cannot be drawn based on the data at this time. Future research analyzing external variables such as patient compliance, provider biases, and population risk, may be useful in providing further insight to explain the statistical significance of this data
