We present what we believe to be a new application of scanning holographic microscopy to superresolution. Spatial resolution exceeding the Rayleigh limit of the objective is obtained by digital coherent addition of the reconstructions of several off-axis Fresnel holograms. Superresolution by holographic superposition and synthetic aperture has a long history, which is briefly reviewed. The meth...
A deep understanding of natural decadal variability is pivotal to discuss recently observed climate trends. Paleoclimate proxies allow reconstructing natural variations before the instrumental period. Typically, regional-scale reconstructions depend on factors like dating, multi-proxy weighting and calibration, which may lead to non-robust reconstructions. Riverine records inherently integrate ...
Large-scale climate history of the past millennium reconstructed solely from tree-ring data is prone to underestimate the amplitude of low-frequency variability. In this paper, we aimed at solving this problem by utilizing a novel method termed "MDVM", which was a combination of the ensemble empirical mode decomposition (EEMD) and variance matching techniques. We compiled a set of 211 tree-ring...
We investigate the extension of previous work by Krishnaswami et al. in [6] on Handwaving Logic, a logic that can be effectively modeled by Fairtlough and Mendler’s Lax Logic [4], towards trying to achieve a reasonable formalization of ”drunken logic.” More advanced formalizations of drunken logic fail to be modeled effectively by lax logic, and we argue that much more study deserves to be paid...
Smoldering and flaming fires, which emit different proportions of organic (OC) and black carbon (BC, in the form of char and soot), have long been recognized in modern wildfire observations but never in a paleo-record, and little is known about their interactions with climate. Here we show that in the late glacial-early Holocene transition period, when the climate was moist, relatively high qua...
Events with a leptonic W -decay plus jets should contain top-quark signals, but a QCD W + jets background must be separated. We compare transverse W -momentum, jet multiplicity, and b-tagging separation criteria, and find that the main background after tagging comes from mistagging. We illustrate how to extract the mass mt via event reconstructions and how to confirm signal purity by lepton ang...
M any different physicians perform cosmetic and reconstructive surgical procedures of the face. Limited studies have suggested that medical students are most likely to choose a plastic surgeon or an oral and maxillofacial surgeon for various facial procedures. To our knowledge, these limited studies have not involved more than several hundred medical students in limited geographic areas. Owing ...
OBJECTIVES To provide an analytical overview of contemporary indications, techniques, and outcomes of urologic minilaparoscopy (ML) in multiple European centers. METHODS Data of patients who had undergone a minilaparoscopic urologic procedure at nine European institutions between 2009 and 2012 were retrospectively gathered. Surgical procedures were classified as upper or lower urinary tract a...
Atomic structures obtained by electron microscopy for tubulin, and by X-ray crystallography for bacterial FtsZ, show that the two proteins are highly homologous. The complementarity between such high-resolution studies and low-resolution reconstructions of microtubule complexes is clear, but controversy still abounds.
