Dust Detection in Satellite Data using Convolutional Neural Networks
(HPCF UMBC, 2019)Atmospheric dust is known to cause health ailments and impacts earth’s climate and weather patterns. Due to the many issues atmospheric dust contributes to, it is important to study dust patterns and how it enters the ... -
Turbulence-free two-photon double-slit interference with coherent and incoherent light
(Optical Society of America, 2019-11-11)This article reports a study on a turbulence-free Young’s double-slit interferometer. When the environmental turbulence blurs out the classic Young’s double-slit interference completely, a two-photon interference pattern ... -
Quantum speed limits and the maximal rate of entropy production
(2019-10-16)The Bremermann-Bekenstein bound sets a fundamental upper limit on the rate with which information can be processed. However, the original treatment heavily relies on cosmological properties and plausibility arguments. In ... -
Orthogonality Catastrophe as a Consequence of the Quantum Speed Limit
(2019-10-25)A remarkable feature of quantum many-body systems is the orthogonality catastrophe which describes their extensively growing sensitivity to local perturbations and plays an important role in condensed matter physics. Here ... -
Bosons Outperform Fermions – The Thermodynamic Advantage of Symmetry
(2019-10-11)We examine a quantum Otto engine with a harmonic working medium consisting of two particles to explore the use of wave function symmetry as an accessible resource. It is shown that the bosonic system displays enhanced ... -
Large Deflections of Inextensible Cantilevers: Modeling, Theory, and Simulation
(2019-10-16)A recent large deflection cantilever model is considered. The principal nonlinear effects come through the beam’s inextensibility—local arc length preservation—rather than traditional extensible effects attributed to ... -
Benchmarking Parallel K-Means Cloud Type Clustering from Satellite Data
(Springer, Cham, 2019-10-08)The study of clouds, i.e., where they occur and what are their characteristics, plays a key role in the understanding of climate change. Clustering is a common machine learning technique used in atmospheric science to ... -
Engineering of Large Third-Order Nonlinearities in Atomic Layer Deposition Grown Nitrogen-Enriched TiO₂
(ACS Publications, 2019-10-17)The third-order nonlinear optical properties of Nitrogen-enriched TiO₂ films deposited by Atomic Layer Deposition (ALD) at a temperature between 100 – 300°C on quartz substrates were studied using thermally managed Z-scan ... -
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 ...
