Where Does Work End and Home Life Begin?
(IGI Global Disseminator of Knowledge, 2009)Many years ago, it was a commonly held belief that technology would improve industries and service professions, which means that people could work shorter hours and their employers would make just as much money. Essentially, ... -
The Origin of the X-Ray Emission in Two Well-aligned Extragalactic Jets: The Case for IC/CMB
(The American Astronomical Society, 2019-09-17)Over the past two decades, the most commonly adopted explanation for high and hard X-ray emission in resolved quasar jets has been inverse-Compton upscattering of the cosmic microwave background (IC/CMB), which requires ... -
Why do females sing?—pair communication and other song functions in eastern bluebirds
(Oxford University Press, 2019-08-03)Female bird song has been underappreciated and understudied, especially in temperate species. Birdsong was originally thought to be a trait used primarily by male songbirds for mate attraction and male/male contest. However, ... -
Generating photon-added states without adding a photon
(The American Physical Society, 2019-10-02)We show that a continuous range of nonclassical states of light can be generated using conditional measurements on the idler mode of an optical parametric amplifier. The output state is prepared by introducing a coherent ... -
Survival of the fittest: how myeloid‑derived suppressor cells survive in the inhospitable tumor microenvironment
(Springer Berlin Heidelberg, 2019-09-09)Myeloid-derived suppressor cells (MDSC) are present in most cancer patients where they are signifcant contributors to the immune suppressive tumor microenvironment (TME). The TME is a hostile locale due to defciencies in ... -
Myeloid-Derived Suppressor Cells: Not Only in Tumor Immunity
(Frontiers Media S.A., 2019-05-15)Since the realization that immature myeloid cells are powerful modulators of the immune response, many studies on “myeloid-derived suppressor cells” (MDSCs) have documented their ability to promote tumor progression in ... -
The Accretion History of AGN: A Newly Defined Population of Cold Quasars
(2019-08-15)Quasars are the most luminous of active galactic nuclei (AGN), and are perhaps responsible for quenching star formation in their hosts. The Stripe 82X catalog covers 31.3 deg² of the Stripe 82 field, of which the 15.6 deg² ... -
Top-down Proteomic Characterization of Truncated Proteoforms
(ACS Publications, 2019-09-10)A top-down proteomic strategy with semi-automated analysis of data sets has proven successful for global identification of truncated proteins without the use of chemical derivatization, enzymatic manipulation, immunoprecipitation ... -
Analytically parameterized solutions for robust quantum control using smooth pulses
(2019-06)Achieving high-fidelity control of quantum systems is essential for realization of a practical quantum computer. Composite pulse sequences which suppress different types of errors can be nested to suppress a wide variety ... -
Long-Wavelength Reflecting Filters Found in the Larval Retinas of One Mantis Shrimp Family (Nannosquillidae)
(Elsevier B.V., 2019-09-23)Both vertebrates and invertebrates commonly exploit photonic structures adjacent to their photoreceptors for visual benefits. For example, use of a reflecting structure (tapetum) behind the retina increases photon capture, ... -
Differential Regulation of T-cell Immunity and Tolerance by Stromal Laminin Expressed in the Lymph Node
(Wolters Kluwer Health, 2019-10-01)Background. Stromal laminins α4 and α5 are differentially regulated in transplant tolerance and immunity, respectively, resulting in altered T-cell trafficking. We hypothesized that laminins directly regulated T-cell ... -
Effects of Lyse-It on endonuclease fragmentation, function and activity
(PLOS, 2019-09-30)Nucleases are enzymes that can degrade genomic DNA and RNA that decrease the accuracy of quantitative measures of those nucleic acids. Here, we study conventional heating, standard microwave irradiation, and Lyse-It, a ... -
Velocity-dependent optical forces and Maxwell’s demon
(Nature, 2019-09-24)An atom placed in a focused laser beam will experience a dipole force due to the gradient in the interaction energy, which is analogous to the well-known optical tweezers effect. This force will be dependent on the velocity ... -
Numerical efficacy study of data assimilation for the 2D magnetohydrodynamic equations
(American Institute of Mathematical Sciences, 2019-06)We study the computational efficiency of several nudging data assimilation algorithms for the 2D magnetohydrodynamic equations, using varying amounts and types of data. We find that the algorithms work with much less ... -
NOD-CC: A Hybrid CBR-CNN Architecture for Novel Object Discovery
(Springer, Cham, 2019-08-09)Deep Learning methods have shown a rapid increase in popularity due to their state-of-the-art performance on many machine learning tasks. However, these methods often rely on extremely large datasets to accurately train ... -
Lisinopril preserves physical resilience and extends life span in a genotype-specific manner in Drosophila melanogaster
(Oxford University Press, 2019-06-14)Physical resiliency declines with age and comorbid conditions. In humans, Angiotensin Converting Enzyme (ACE) has been associated with attenuation of the decline in physical performance with age. ACE-inhibitor (ACEi) ... -
Data Compression for Optimization of a Molecular Dynamics System: Preserving Basins of Attraction
(Springer, Cham, 2019-06-08)Understanding the evolution of atomistic systems is essential in various fields such as materials science, biology, and chemistry. The gold standard for these calculations is molecular dynamics, which simulates the dynamical ... -
Production of reproductively sterile fish by a non-transgenic gene silencing technology
(Nature, 2015-10-29)We developed a novel bath-immersion technology to produce large numbers of infertile fish. As seafood consumption shifts from fishery harvests towards artificially propagated species, optimization of aquaculture practices ... -
Functionally Significant Features in the 5' Untranslated Region of the ABCA1 Gene and Their Comparison in Vertebrates
(MDPI, 2019-06-21)Single nucleotide polymorphisms located in 5' untranslated regions (50UTRs) can regulate gene expression and have clinical impact. Recognition of functionally significant sequences within 5' UTRs is crucial in next-generation ... -
Transmission characteristics of optical nanofibers in metastable xenon
(2019-06-17)We study the transmission characteristics of sub-wavelength diameter silica optical nanofibers (ONF’s) surrounded with a xenon plasma produced by a low-pressure inductive RF discharge. In contrast to related experiments ...
