AutoShrink: A Topology-aware NAS for Discovering Efficient Neural Architecture. (arXiv:1911.09251v1 [cs.LG])

Science, StatisticsLeave a comment

Resource is an important constraint when deploying Deep Neural Networks (DNNs) on mobile and edge devices. Existing works commonly adopt the cell-based search approach, which limits the flexibility of network patterns in learned cell structures. Moreover, due to the topology-agnostic nature of existing works, including both cell-based and node-based approaches, the search process is time…

Spline Analysis of Biomarker Data Pooled From Multiple Matched/Nested Case-Control Studies. (arXiv:1911.09254v1 [stat.ME])

Science, StatisticsLeave a comment

Pooling biomarker data across multiple studies enables researchers to get more precise estimates of the association between biomarker exposure measurements and disease risks due to increased sample sizes. However, biomarker measurements vary significantly across different assays and laboratories, and therefore calibration of the local laboratory measurements to a reference laboratory is necessary before pooling data.…

Air, bone and soft-tissue Segmentation on 3D brain MRI Using Semantic Classification Random Forest with Auto-Context Model. (arXiv:1911.09264v1 [physics.med-ph])

Physics, ScienceLeave a comment

As bone and air produce weak signals with conventional MR sequences, segmentation of these tissues particularly difficult in MRI. We propose to integrate patch-based anatomical signatures and an auto-context model into a machine learning framework to iteratively segment MRI into air, bone and soft tissue. The proposed semantic classification random forest (SCRF) method consists of…

An optical test bench for the precision characterization of absolute quantum efficiency for the TESS CCD detectors. (arXiv:1911.09270v1 [astro-ph.IM])

Physics, ScienceLeave a comment

The Transiting Exoplanet Survey Satellite (TESS) will search for planets transiting bright stars with Ic<13. TESS has been selected by NASA for launch in 2018 as an Astrophysics Explorer mission, and is expected to discover a thousand or more planets that are smaller in size than Neptune. TESS will employ four wide-field optical charge-coupled device…

Doubling the near-infrared photocurrent in a solar cell via omni-resonant coherent perfect absorption. (arXiv:1911.09276v1 [physics.optics])

Physics, ScienceLeave a comment

Minimizing the material usage in thin-film solar cells can reduce manufacturing costs and enable mechanically flexible implementations, but concomitantly diminishes optical absorption. Coherent optical effects can help alleviate this inevitable drawback at discrete frequencies. For example, coherent perfect absorption guarantees that light is fully absorbed in a thin layer regardless of material or thickness but…

Analysis of peristaltic pumping patterns in closed elastic tubes. (arXiv:1911.09286v1 [physics.flu-dyn])

Physics, ScienceLeave a comment

Balloon dilation catheters are often used to quantify the physiological state of peristaltic activity in tubular organs and comment on its ability to propel fluid which is important for healthy human function. To fully understand this system’s behavior, we analyze the effect of a solitary peristaltic wave on a fluid-filled elastic tube with closed ends.…

Multi-level scalar structure in complex system analyses. (arXiv:1911.09294v1 [physics.flu-dyn])

Physics, ScienceLeave a comment

The geometrical structure is among the most fundamental ingredients in understanding complex systems. Is there any systematic approach in defining structures quantitatively, rather than illustratively? If yes, what are the basic principles to follow? By introducing the concept of extremal points at different scale levels, a multi-level dissipation element approach has been developed to define…

Subfemtosecond glory hologrammetry for vectorial optical waveform reconstruction. (arXiv:1911.09297v1 [physics.atom-ph])

Physics, ScienceLeave a comment

In this paper, we propose a new method to characterize the temporal structure of arbitrary optical laser pulses with low pulse energies. This approach is based on strong field photoelectron holography with the glory rescattering effect as the underlying mechanism in the near-forward direction. Utilizing the subfemtosecond glory rescattering process as a fast temporal gate…

Bayesian optimization with local search. (arXiv:1911.09159v1 [stat.ML])

Mathematics (math), ScienceLeave a comment

Global optimization finds applications in a wide range of real world problems. The multi-start methods are a popular class of global optimization techniques, which are based on the ideas of conducting local searches at multiple starting points, and then sequentially determine the starting points according to some prescribed rules. In this work we propose a…

Positive solutions to the sublinear Lane-Emden equation are isolated. (arXiv:1911.09163v1 [math.AP])

Mathematics (math), ScienceLeave a comment

We prove that on a smooth bounded set, the positive least energy solution of the Lane-Emden equation with sublinear power is isolated. As a corollary, we obtain that the first $q-$eigenvalue of the Dirichlet-Laplacian is not an accumulation point of the $q-$spectrum, on a smooth bounded set. Our results extend to a suitable class of…
