Comparison and validation of point spread models for imaging in natural waters (2008)

It is known that scattering by particulates within natural waters is the main cause of the blur in underwater images. Underwater images can be better restored or enhanced with knowledge of the point spread function (PSF) of the water. This will extend the performance range as well as the information retrieval from underwater electro-optical systems, which is critical in many civilian and military applications, including target and especially mine detection, search and rescue, and diver visibility. A better understanding of the physical process involved also helps to predict system performance and simulate it accurately on demand. The presented effort first reviews several PSF models, including the introduction of a semi-analytical PSF given optical properties of the medium, including scattering albedo, mean scattering angles and the optical range. The models under comparison include the empirical model of Duntley, a modified PSF model by Dolin et al, as well as the numerical integration of analytical forms from Wells, as a benchmark of theoretical results. For experimental results, in addition to that of Duntley, we validate the above models with measured point spread functions by applying field measured scattering properties with Monte Carlo simulations. Results from these comparisons suggest it is sufficient but necessary to have the three parameters listed above to model PSFs. The simplified approach introduced also provides adequate accuracy and flexibility for imaging applications, as shown by examples of restored underwater images.

Mössbauerite, Fe63+O4(OH)8[CO3]·3H2O, the fully oxidized ‘green rust’ mineral from Mont Saint-Michel Bay, France (2014)

Abstract The new mineral mössbauerite (IMA2012−049), Fe 6 3+ O 4 (OH) 8 [CO 3 ]·3H 2 O, is a member of the fougèrite group of the hydrotalcite supergroup. Thus, it has a layered double hydroxide-type structure, in which brucite-like layers [Fe 6 3+ O 4 (OH) 8 ] 2+ are intercalated with CO 3 2− anions and water molecules. Mössbauerite is the fully oxidized analogue of fougèrite and trébeurdenite, related to them chemically by the exchange of (Fe 3+ O 2− ) with (Fe 2+ OH − ). Mössbauerite, intimately intergrown with trébeurdenite, was discovered in intertidal gleys from Mont Saint-Michel Bay, France, along with quartz, feldspars and clay minerals. Mössbauerite is formed by the oxidation of the other members of the fougèrite group. Like them, it occurs as μm-scale platelets in gleys with restricted access to atmospheric O and decomposes rapidly when exposed to air. Identification and characterization of these minerals has relied on an electrochemical study of synthetic analogues and Mössbauer spectroscopy, which inspired the name of the new mineral. Unlike fougèrite and trébeurdenite, which are blue-green, pure synthetic mössbauerite is orange in colour. Detailed optical and other physical properties could not be determined because of the small platelet size and instability. The hardness is probably 2−3, by analogy with other members of the supergroup and the density, calculated from unit-cell parameters, is 2.950 g/cm 3 . Synchrotron X-ray data indicate that the natural material is a nanoscale intergrowth of 2 T and 3T polytypes; the latter probably has the 3T 7 stacking sequence. The corresponding maximum possible space group symmetries are P m 1 and P 3 m 1. Unit-cell parameters for the 3 T cell are a = 3.032(7) Å, c = 22.258(4) = 367.420 Å and Z = ½. Mössbauer spectroscopy at 78 K indicates that two distinct Fe 3+ environments exist in a 2:1 ratio. These are interpreted to be ordered within each layer, but without the development of a threedimensional superlattice. Mössbauerite undergoes gradual magnetic ordering at 70−80 K to a ferromagnetic state, below which it splits into three sextets S 1m , S 2m and S 3m , as measured at 15 K, and shows the same intensity ratio ½:⅙:⅓ as the three doublets for fougèrite D 1f , D 2f , D 3f in the paramagnetic state at 78 K. This suggests that there is also short-range coupling of interlayer carbonate anions with respect to the octahedral layers and that the 2D long-range order of carbonates in interlayers remains unchanged.
Magnetization of modulation doped Si/SiGe quantum wells in high magnetic fields (2005)

We have fabricated highly sensitive micromechanical cantilever magnetometers and, by this means, investigated the de Haas‐van Alphen effect of a two‐dimensional electron system in a modulation‐doped Si/SiGe heterostructure. As a function of perpendicular magnetic field component B⊥ we observe at low temperature sawtooth‐like oscillations of the magnetization M. These are found at even integer filling factors v = ns/(eB⊥/h) = 4(N + 1) with N = 0, 1, 2…, when the chemical potential is in the Landau energy gap, and at v = (4N + 2) where the spin splitting of the Landau levels occurs. In particular, we also observe oscillations at odd v where the valley degeneracy is lifted. This signal increases significantly with B⊥. We discuss our findings in the framework of electron‐electron interaction in the presence of disorder.
Batch-Size Independent Regret Bounds for the Combinatorial Multi-Armed\n Bandit Problem (2019)

We consider the combinatorial multi-armed bandit (CMAB) problem, where the\nreward function is nonlinear. In this setting, the agent chooses a batch of\narms on each round and receives feedback from each arm of the batch. The reward\nthat the agent aims to maximize is a function of the selected arms and their\nexpectations. In many applications, the reward function is highly nonlinear,\nand the performance of existing algorithms relies on a global Lipschitz\nconstant to encapsulate the function's nonlinearity. This may lead to loose\nregret bounds, since by itself, a large gradient does not necessarily cause a\nlarge regret, but only in regions where the uncertainty in the reward's\nparameters is high. To overcome this problem, we introduce a new smoothness\ncriterion, which we term \\emph{Gini-weighted smoothness}, that takes into\naccount both the nonlinearity of the reward and concentration properties of the\narms. We show that a linear dependence of the regret in the batch size in\nexisting algorithms can be replaced by this smoothness parameter. This, in\nturn, leads to much tighter regret bounds when the smoothness parameter is\nbatch-size independent. For example, in the probabilistic maximum coverage\n(PMC) problem, that has many applications, including influence maximization,\ndiverse recommendations and more, we achieve dramatic improvements in the upper\nbounds. We also prove matching lower bounds for the PMC problem and show that\nour algorithm is tight, up to a logarithmic factor in the problem's parameters.\n

A SFTPC BRICHOS mutant links epithelial ER stress and spontaneous lung fibrosis (2019)

Alveolar type 2 (AT2) cell endoplasmic reticulum (ER) stress is a prominent feature in adult and pediatric interstitial lung disease (ILD and ChILD), but in vivo models linking AT2 cell ER stress to ILD have been elusive. Based on a clinical ChILD case, we identified a critical cysteine residue in the surfactant protein C gene (SFTPC) BRICHOS domain whose mutation induced ER stress in vitro. To model this in vivo, we generated a knockin mouse model expressing a cysteine-to-glycine substitution at codon 121 (C121G) in the Sftpc gene. SftpcC121G expression during fetal development resulted in a toxic gain-of-function causing fatal postnatal respiratory failure from disrupted lung morphogenesis. Induced SftpcC121G expression in adult mice resulted in an ER-retained pro-protein causing AT2 cell ER stress. SftpcC121G AT2 cells were a source of cytokines expressed in concert with development of polycellular alveolitis. These cytokines were subsequently found in a high-dimensional proteomic screen of bronchoalveolar lavage fluid from ChILD patients with the same class of SFTPC mutations. Following alveolitis resolution, SftpcC121G mice developed spontaneous pulmonary fibrosis and restrictive lung impairment. This model provides proof of concept linking AT2 cell ER stress to fibrotic lung disease coupled with translationally relevant biomarkers.
Esculentin‐1b(1–18) – a membrane‐active antimicrobial peptide that synergizes with antibiotics and modifies the expression level of a limited number of proteins in Escherichia coli (2009)

Antimicrobial peptides constitute one of the main classes of molecular weapons deployed by the innate immune system of all multicellular organisms to resist microbial invasion. A good proportion of all antimicrobial peptides currently known, numbering hundreds of molecules, have been isolated from frog skin. Nevertheless, very little is known about the effect(s) and the mode(s) of action of amphibian antimicrobial peptides on intact bacteria, especially when they are used at subinhibitory concentrations and under conditions closer to those encountered in vivo. Here we show that esculentin-1b(1-18) [Esc(1-18)] (GIFSKLAGKKLKNLLISG-NH(2)), a linear peptide encompassing the first 18 residues of the full-length esculentin-1b, rapidly kills Escherichia coli at the minimal inhibitory concentration. The lethal event is concomitant with the permeation of the outer and inner bacterial membranes. This is in contrast to what is found for many host defense peptides, which do not destabilize membranes at their minimal inhibitory concentrations. Importantly, proteomic analysis revealed that Esc(1-18) has a limited ability to modify the bacterium's protein expression profile, at either bactericidal or sublethal concentrations. To the best of our knowledge, this is the first report on the effects of an antimicrobial peptide from frog skin on the proteome of its bacterial target, and underscores the fact that the bacterial membrane is the major target for the killing mechanism of Esc(1-18), rather than intracellular processes.

Cystic Artery Pseudoaneurysm: Over Warfarinisation and Management (2013)

Cystic artery pseduoaneurym is a rare cause of haemobilia. A 78 year old man who was over-warfarinised, developed jaundice, upper abdominal pain and melena. He also required blood transfusions due to rapidly reducing haemoglobin. Computed tomography showed a cystic artery pseudoaneurysm caused by possible cholecystitis or gallbladder cancer. He successfully underwent angiographic coil embolisation. Haemobilia should be considered a differential cause of gastrointestinal bleeding if the above clinical features are present and especially if the patient is over anticoagulated.

Extrinsic parameters calibration of multi-camera with non-overlapping fields of view using laser scanning (2019)

An extrinsic parameters calibration method of multi-cameras with non-overlapping fields of view (FOV) using laser scanning is presented. Firstly, two lasers are mounted on a multi-degree-of-freedom manipulator and can scan objects freely by the projected line-structured light. Then, controlling the movement of the manipulator, the line-structured light is projected into the field of view of one of the multi-cameras, and the light plane equation in the camera coordinate frame is calibrated by the target. The manipulator is moved several times in small amplitude to change the position of structured light in the field of vision of the camera and to continue to calibrate the light plane. The light plane equation of line-structured light in the manipulator coordinate frame are solved by the hand-eye calibration method. Secondly, with the help of the light planes, projected into the field of vision of other cameras to be calibrated, the light plane equation in the camera coordinate frame is calibrated, and the external parameters between the camera coordinate frame and the manipulator coordinate frame are calculated, so that the calibration of the external parameters of multiple cameras can be realized. The proposed method connects the non-overlapping multi-cameras by the laser scanning. It can effectively solve the problem of multi-camera extrinsic parameter calibration under the conditions of long working distance and complex environment light.

THE BLOOD CYANATES IN THE TREATMENT OF HYPERTENSION (1936)

A few years ago I gave a number of patients with hypertension potassium or sodium thiocyanate with results that were generally unsatisfactory. Some showed extreme weakness, nausea and dizziness, while an occasional one seemed to be considerably improved as far as the symptoms and blood pressure level were concerned. In general, it seemed that older patients or those who had a blood pressure elevation over a long period of time seemed to tolerate cyanate therapy less well than the younger group. Careful observation indicated that individual dosage was necessarily dependent on the individual response and the toxicity. An attempt has been made, therefore, to gage the dosage by a study of the cyanate clearance from the body through the urine and a correlation by the blood cyanate level and the blood pressure. The following material is being presented as a preliminary report on such observations extending over a period of
Pharmacotherapy of overactive bladder: epidemiology and pathophysiology of overactive bladder (2011)

With recent advances in our understanding of the basic science of OAB, it is becoming clear that the control of bladder function is far more complex than previously believed. Recent research has highlighted several potential targets for the treatment of OAB, particularly within the mechanosensory pathways.
Mode of cytotoxic action of pseudomonal leukocidin on phosphatidylinositol metabolism and activation of lysosomal enzyme in rabbit leukocytes (1984)

The cytotoxic action of leukocidin from Pseudomonas aeruginosa was supported by the following observations. (i) The destruction of rabbit leukocytes by the toxin was reduced in the absence of Ca2+ and stimulated by the addition of calcium ionophore A23187 but inhibited by EDTA, EGTA, and TMB-8, an antagonist of intracellular Ca2+ transport. (ii) Uptake of 45Ca into leukocytes exposed to the toxin was enhanced about threefold the rate of uptake into untreated cells. The increased 45Ca uptake into the cells was slightly inhibited by trifluoperazine, an inhibitor of Ca2+-calmodulin activity, but not by ruthenium red. (iii) Pseudomonal leukocidin enhanced rapidly the labeling of phosphatidylinositol, polyphosphoinositides, phosphatidic acid, and lysophosphatidic acid from [32P]phosphate. The time course experiments of the labeling and breakdown of these phospholipids suggested that the initial action of this toxin was to stimulate phosphatidic acid production, presumably causing a rapid metabolic change of phosphatidylinositol correlating with the activities of phosphatidylinositol-specific phospholipase C and 1,2-diacylglycerol kinase. It was considered that a rapid formation of phosphatidic acid and degradation of polyphosphoinositides might be related to a Ca2+ movement from extra- and intracellular space. (iv) In leukocytes exposed to the toxin, acid phosphatase activity as a marker enzyme of lysosome was activated up to 75% of the lysosomal enzyme before cell destruction. The leakage of lysosomal enzyme from the cells occurred at the almost same time as leukocyte destruction. The mode of cytotoxic action of pseudomonal leukocidin is discussed.

Multiwavelength optically controlled phased-array antennas (1998)

A novel multiwavelength scheme is proposed and demonstrated for one-dimensional (1-D) and two-dimensional (2-D) optically controlled phased-array antenna (OCPAA) systems with true time delay (TTD). This hardware-compressive architecture employs a multiwavelength laser source in conjunction with a programmable dispersion matrix (PDM) and switched optical delay lines (SODLs) to generate all the required time delays for beam steering in 2-D phased-array antenna systems. Independent control of elevation and azimuthal scan is achieved by combining wavelength-dependent and wavelength-independent time delays. An experimental prototype of 4/spl times/2 array with 2-b/spl times/2-b resolution is constructed to demonstrate the feasibility of the multiwavelength OCPPA (MWOCPAA). Broadband linear RF phase shift is measured in both elevation and azimuthal planes over the entire bandwidth of the electro-optic (EO) modulator. System issues such as insertion loss, array size, and channel isolation are discussed. Extension of the multiwavelength scheme to a common transmit/receive (T/R) module with TTD is also described.

Abstract MP70: Conventional and Novel Lipid Measures and Subsequent Risk of Lower-extremity Peripheral Artery Disease: The Atherosclerosis Risk in Communities (aric) Study (2020)

Introduction: The association of conventional lipids (total cholesterol, low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], and triglycerides [TG]) with incident peripheral artery diseases (PAD) has been reported. Understanding novel lipids (remnant lipoprotein cholesterol [RLP-C], LDL-TG, small dense LDL-C [sdLDL-C], Apo-E containing HDL [ApoE-HDL]) in this regard could inform risk classification and preventive approaches for PAD. Hypothesis: Some novel lipids will be more evidently related to incident PAD than some conventional lipid measures. Methods: In 8808 ARIC participants (mean age 62.6 [SD 5.7] y) free of PAD at baseline (visit 4, 1996-98), we assessed the associations of each lipid measure (as quartiles and continuous variable) and incident PAD-related hospitalization through 2015 using multivariable Cox models. Since some lipids are closer biologically correlated than others, indicating collective effects among lipids, we used factor analysis to identify underlying factors and modeled them for PAD risk. Results: There were 262 incident PAD cases. After accounting for potential confounders, HDL-C, TG, RLP-C, LDL-TG, and ApoE-HDL were independently associated with incident PAD, with the largest hazard ratio between Q4 and Q1 for HDL-C (Table). LDL-C showed a J-shaped association, and Q4 and Q3 became significant when compared to Q2 (1.57 [1.09-2.25] and 1.46 [1.02-2.11], respectively). The associations of LDL-TG, and ApoE-HDL remained significant after adjusting for LDL-C. The factor analysis identified 3 factors (Factor 1: mainly loaded by TG, RLC, LDL-TG and sdLDL-C; Factor 2: by total cholesterol, LDL-C, and sdLDL-C; Factor 3: by HDL-C and ApoE-HDL), and only Factor 3 showed an independent association with incident PAD (0.78 [0.65-0.93]). Conclusions: These findings suggest the importance of HDL-related and TG-related lipids in the development of PAD, with potential therapeutic implications.
