Retinal Fundus Multi-Disease Image Dataset (RFMiD): A Dataset for Multi-Disease Detection Research (2021)

The world faces difficulties in terms of eye care, including treatment, quality of prevention, vision rehabilitation services, and scarcity of trained eye care experts. Early detection and diagnosis of ocular pathologies would enable forestall of visual impairment. One challenge that limits the adoption of computer-aided diagnosis tool by ophthalmologists is the number of sight-threatening rare pathologies, such as central retinal artery occlusion or anterior ischemic optic neuropathy, and others are usually ignored. In the past two decades, many publicly available datasets of color fundus images have been collected with a primary focus on diabetic retinopathy, glaucoma, age-related macular degeneration and few other frequent pathologies. To enable development of methods for automatic ocular disease classification of frequent diseases along with the rare pathologies, we have created a new Retinal Fundus Multi-disease Image Dataset (RFMiD). It consists of 3200 fundus images captured using three different fundus cameras with 46 conditions annotated through adjudicated consensus of two senior retinal experts. To the best of our knowledge, our dataset, RFMiD, is the only publicly available dataset that constitutes such a wide variety of diseases that appear in routine clinical settings. This dataset will enable the development of generalizable models for retinal screening.

Asymmetry of cerebral autoregulation does not correspond to asymmetry of cerebrovascular pressure reactivity (2012)

Small cerebral vessels respond to variations of cerebral perfusion pressure (CPP) by changes of vessel diameter inducing changes of blood flow resistance and keeping cerebral blood flow constant. This mechanism is called cerebral autoregulation (CA). Recently stronger reactions of CA during pressure increase than during decrease were reported. Aim of this study was to assess the symmetry behavior of CA during spontaneous CPP changes and compare it to cerebrovascular pressure reactivity (CVR). In 238 patients with traumatic brain injury or stroke, correlation indices between CPP and cerebral blood flow velocity (CBFV) were calculated during periods of increasing (upMx) and decreasing CPP (downMx). The indices range from −1 to +1, values ≤0 indicating intact, values >0 indicating impaired autoregulation. Similar correlation between arterial blood pressure (ABP) and ICP was calculated during increasing (upPRx) and decreasing ABP (downPRx), negative values indicating intact, positive values indicating impaired CVR. Only recordings with strong pressure changes (CPP/ABP > 10 mmHg) were evaluated. CA was assessed in 62 patients. On average (mean ± SD) upMx was 0.06 ± 0.52, downMx was 0.15 ± 0.55 (P < 0.005). CVR was assessed in 47 patients. On average upPRx was 0.45 ± 0.43, downPRx was 0.38 ± 0.48 (P < 0.05). In 40 patients both Mx and PRx were calculated. On average upMx was 0.21 ± 0.55 and downMx was 0.27 ± 0.56 (P = 0.05), upPRx was 0.35 ± 0.43 and downPRx was 0.27 ± 0.47 (P < 0.05). During pressure increase the autoregulatory response was significantly stronger than during decrease, while in contrast the cerebrovascular reactivity was significantly weaker. The reason for this opposed behavior remains unclear and needs further exploration.
Continuous Wasserstein-2 Barycenter Estimation without Minimax Optimization (2021)

Wasserstein barycenters provide a geometric notion of the weighted average of probability measures based on optimal transport. In this paper, we present a scalable algorithm to compute Wasserstein-2 barycenters given sample access to the input measures, which are not restricted to being discrete. While past approaches rely on entropic or quadratic regularization, we employ input convex neural networks and cycle-consistency regularization to avoid introducing bias. As a result, our approach does not resort to minimax optimization. We provide theoretical analysis on error bounds as well as empirical evidence of the effectiveness of the proposed approach in low-dimensional qualitative scenarios and high-dimensional quantitative experiments.
Design of Optimal Operating Conditions of Simulated Moving Bed Adsorptive Separation Units (1995)

The design of the optimal operating conditions for simulated moving bed (SMB) adsorptive separation units is considered. A procedure for the a priori selection of the operating conditions to achieve an assigned separation requirement is developed in the frame of equilibrium theory for the equivalent four section countercurrent unit, using a model where the adsorption equilibria are described through the constant selectivity stoichiometric model, while both mass transfer resistance and axial dispersion are neglected. The space of the operating parameters, i.e. the mass now rate ratios m(j), is divided in regions with different separation regimes. Curves at constant outlets purity and recovery are drawn in the (m(2),m(3)) plane. The introduction of three performance parameters, desorbent requirement, adsorbent requirement, and productivity, allows the development of a procedure for the design of optimal operating conditions. This procedure is completed, accounting for the effect of the switching time on the separation performances, with a detailed model of the SMB unit, considering both axial dispersion and mass transfer resistance. This result constitutes a useful tool for determining the range of operating conditions to achieve an assigned separation requirement and then for selecting the optimal operating condition within this range.
A Pixel-Parallel Self-Similitude Processing for Multiple-Resolution Edge-Filtering Analog Image Sensors (2009)

A pixel-parallel <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">self-similitude</i> computation architecture has been developed for multiple-resolution directional edge filtering based on focal-plane image processing. The <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">self-similitude</i> organization has enabled pixel-by-pixel multiple-resolution image filtering with minimal complexity in interconnects. As a result, it has become possible to accomplish any (1/2) <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n</i> -resolution directional edge filtering in ( <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n</i> +2) steps. An analog edge-filtering chip implemented using a switched floating-gate MOS (neuMOS) technology that is capable of performing four-directional edge filtering at full, half, and quarter resolutions was designed and fabricated in a 0.35-mum 3-metal CMOS technology. The concept has been experimentally verified using the fabricated chip, and the four-directional edge filtering at full, half, and quarter resolutions was demonstrated by measurement.
Cholesterol-induced stimulation of platelet aggregation is prevented by a hempseed-enriched dietThis article is one of a selection of papers published in the special issue Bridging the Gap: Where Progress in Cardiovascular and Neurophysiologic Research Meet. (2008)

Hypercholesterolemia indirectly increases the risk for myocardial infarction by enhancing the ability of platelets to aggregate. Diets enriched with polyunsaturated fatty acids (PUFAs) have been shown to reduce the detrimental effects of cholesterol on platelet aggregation. This study investigated whether dietary hempseed, a rich source of PUFAs, inhibits platelet aggregation under normal and hypercholesterolemic conditions. Male New Zealand white rabbits were fed one of 6 dietary interventions: regular control diet (RG); control diet + 10% hempseed (HP); control diet + 10% partially delipidated hempseed (DHP); control diet + 0.5% cholesterol (OL); control diet + 0.5% cholesterol + 10% hempseed (OLHP); control diet + 5% coconut oil (CO). After 8 weeks, blood was collected to measure ADP- and collagen-induced platelet aggregation and plasma levels of fatty acids, cholesterol, and triglycerides. The hempseed-fed animals (HP and OLHP) displayed elevated plasma levels of PUFAs and a prominent enhancement in 18:3n-6 (gamma-linolenic acid, GLA) levels, a unique PUFA found in hempseed. The cholesterol-supplemented groups (OL and OLHP) had significantly elevated plasma levels of cholesterol and triglycerides, but platelet aggregation was significantly augmented only in the OL group. The addition of hempseed to this diet (OLHP) normalized aggregation. The direct addition of GLA to the OL platelet samples blocked the cholesterol-induced stimulation of platelet aggregation. The results of this study demonstrate that when hempseed is added to a cholesterol-enriched diet, cholesterol-induced platelet aggregation returns to control levels. This normalization is not due to a reduction in plasma cholesterol levels, but may be partly due to increased levels of plasma GLA.

Diode-pumped high-power cw all solid state laser at 266 nm (1999)

The first cw high-power UV laser at 266 nm--DELTATRAIN--is accomplished by frequency doubling the 532 nm output of a diode-pumped Nd:YAG laser with an actively stabilized unidirectional ring cavity based on the novel DELTACONCEPT, where a minimum number of optical components--two mirrors and one prism are used. The symmetrical Brewster-angled beam path through the prism guarantees minimum losses and hence maximum power enhancement and efficiency. The cavity length control is done by moving the prism along its symmetry axis using a piezoelectric element. The beam path in the cavity remains not only completely unaffected during this movement but also unaffected in the first order by small tilts of the prism due to possible imperfection of the piezoelectric element. Furthermore, the stabilization loop has excellent dynamic behavior owing to the small mass of the prism. The name of this concept results from the (Delta) -geometrical configuration of this novel ring resonator. The unique feature of the DELTACONCEPT shown above adopted in the DELTATRAIN results in long term UV power stability, high beam pointing stability, excellent beam profile and reduced effort in alignment. By using Brewster-cut BBO crystals the high-power cw UV laser can deliver 266 nm radiation with an output power of 1.4 Watt at a green pumping power of 5 W.
Completeness of excision and follow up cytology in patients treated with loop excision biopsy (2000)

At long term follow up, patients with CIN who have residual disease are at increased risk of persistent disease and should therefore be followed up regularly with cytology and colposcopy. The findings support national policy of returning women with treated CIN of any grade to normal recall after five years except for cases of CIN3 where excision was incomplete or equivocal. In these cases follow up with annual smear for 10 years is recommended.

A survey of film processing illustrated with poly(ethylene terephthalate) (1978)

Abstract Polymeric films are used to enclose other materials (as for packaging), to carry information (as for magnetic tapes), and as an engineering material (as for capacitor dielectrics). There is an appropriate combination of the bulk and the surface properties engineered to fit each particular use. This duality is illustrated by the “processing for properties” of poly(ethylene terephthalate) films. An overview is presented of stretching, stabilization and relaxation methods of manufacture. These processing techniques, in conjunction with changes in the polymer composition, provide the property levels that are commercially significant.
A numerical method for ocean-acoustic normal modes (1984)

The method of normal modes is frequently used to solve acoustic propagation problems in stratified oceans. The propagation numbers for the modes are the eigenvalues of the boundary value problem to determine the depth dependent normal modes. Errors in the numerical determination of these eigenvalues appear as phase shifts in the range dependence of the acoustic field. Such errors can severely degrade the accuracy of the normal mode representation, particularly at long ranges. In this paper we present a fast finite difference method to accurately determine these propagation numbers and the corresponding normal modes. It consists of a combination of well-known numerical procedures such as Sturm sequences, the bisection method, Newton’s and Brent’s methods, Richardson extrapolation, and inverse iteration. We also introduce a modified Richardson extrapolation procedure that substantially increases the speed and accuracy of the computation.
Pathogenic Role of IL-17-Producing Immune Cells in Obesity, and Related Inflammatory Diseases (2017)

Obesity is associated with low-grade chronic inflammation. Indeed, adipose tissues (AT) in obese individuals are the former site of progressive infiltration by pro-inflammatory immune cells, which together with increased inflammatory adipokine secretion induce adipocyte insulin resistance. IL-17-producing T (Th17) cells are part of obese AT infiltrating cells, and are likely to be promoted by adipose tissue-derived mesenchymal stem cells, as previously reported by our team. Whereas Th17 cell are physiologically implicated in the neutralization of fungal and bacterial pathogens through activation of neutrophils, they may also play a pivotal role in the onset and/or progression of chronic inflammatory diseases, or cancer, in which obesity is recognized as a risk factor. In this review, we will highlight the pathogenic role of IL-17A producing cells in the mechanisms leading to inflammation in obesity and to progression of obesity-related inflammatory diseases.

It is designed to operate at supply voltages less than 400 mV in a low threshold-voltage CMOS technology, and uses a unique "data-caching" memory architecture and "hierarchical bitline" memories to reduce power.
Evolución del peso corporal en corderas de raza churra (2004)

Mesenteric approach is an artery-first approach during pancreaticoduodenectomy (PD). In the present study, we evaluated clinical and oncological benefits of this procedure for pancreatic ductal adenocarcinoma (PDAC) of the pancreas head. Between 2000 and 2015, 237 consecutive PDAC patients underwent PD. Among them, 72 experienced the mesenteric approach (mesenteric group) and 165 the conventional approach (conventional group). A matched-pairs group consisted of 116 patients (58 patients in each group) matched for age, gender, resectability status, and neoadjuvant therapy. Surgical and oncological outcomes were compared between the two groups in unmatched- and matched-pair analyses. Intraoperative blood loss was lower in the mesenteric group than in the conventional group in both resectable PDAC (R-PDAC) and borderline resectable PDAC (BR-PDAC) on unmatched- and matched-pairs analyses (R-PDAC, unmatched: 312.5 vs 510 mL, <i>P</i>=.008; matched: 312.5 vs 501.5 mL, <i>P</i>=.023; BR-PDAC, unmatched: 507.5 vs 935 mL, <i>P</i><.001; matched: 507.5 vs 920 mL, <i>P</i>=.003). Negative surgical margins (R0) and overall survival (OS) rates in the mesenteric group were better in R-PDAC patients (R0 rates, unmatched: 100% vs 87.7%, <i>P</i>=.044; matched: 100% vs 86.7%, <i>P</i>=.045; OS, unmatched: <i>P</i>=.008, matched: <i>P</i>=.021), although there were no significant differences in BR-PDAC patients. Mesenteric approach might reduce blood loss by early ligation of the vessels to the pancreatic head. Furthermore, it might increase R0 rate, leading to improvement of survival for R-PDAC patients. However, R0 and survival rates could not be improved only by the mesenteric approach for BR-PDAC patients. Therefore, effective multidisciplinary treatment is essential to improve survival in BR-PDAC patients.
Generalized coiflets: a new family of orthonormal wavelets (2002)

We generalize an existing family of wavelets, coiflets, by replacing the zero-centered vanishing moment condition on scaling functions by a nonzero-centered one in order to obtain a novel class of compactly supported orthonormal wavelets (we call them generalized coiflets). This generalization offers an additional free parameter i.e., the center of mass of the scaling function, which can be tuned to obtain improved characteristics of the resulting wavelet system such as near-symmetry of the scaling functions and wavelets, near-linear phase of the filter banks, and sampling approximation properties. Therefore, these new wavelets are promising in a broad range of applications in signal processing and numerical analysis.
Chronic urotensin II infusion enhances macrophage foam cell formation and atherosclerosis in apolipoprotein E-knockout mice (2008)

Our results provide the first evidence that increased plasma urotensin II level stimulates oxidized low-density lipoprotein and reactive oxygen species production and macrophage foam cell formation via increased expression of CD36, scavenger receptor class A, and acyl-CoA:cholesterol acyltransferase-1, contributing to the development of atherosclerosis in apolipoprotein E-deficient mice. Urotensin II receptor antagonism may be a promising therapeutic strategy against atherosclerosis.
Review article: defining remission in ulcerative colitis (2011)

A standard based on clinical symptoms and endoscopy is proposed. Histopathology is a third dimension of remission that may have prognostic value. The definition of remission should help predict long-term outcome. The expectations of patients and their physicians need to be raised, as the goal of treatment of active ulcerative colitis should be to induce remission.

Diagnosis and Therapy of Polycythemia Vera (2006)

Polycythemia vera (PV) is a hematopoietic stem cell disorder characterized by a predominant proliferation of the erythroid cell line. The diagnosis is commonly based on the WHO criteria. The acquired V617F mutation in the tyrosine kinase gene JAK2 represents a new molecular marker proving clonality in PV and other chronic myeloproliferative disorders. Phlebotomy is still the treatment of choice to reduce the red cell mass. Low-dose acetylsalicylic acid is successful in the primary prophylaxis of vascular complications. However, the majority of patients require myelosuppressive therapy during the course of their disease due to progressive myeloproliferation. Hydroxyurea still plays a role in patients of all age groups. Interferon alpha represents an alternative, particularly for younger patients. Apart from sporadic cases of bone marrow transplantation, there is no known curative treatment in PV. To date, the diagnosis of PV was based mainly on clinical criteria. The identification of the JAK2 mutation enables new approaches to the diagnosis, classification, and treatment of PV and of the other myeloproliferative disorders.
Solid phase epitaxial regrowth of amorphous silicon on molecular beam epitaxial silicon/Si layers (1983)

The recrystallization and epitaxial regrowth of amorphous silicon layers on molecular beam epitaxial (MBE) silicon at 650 °C is described. MBE silicon layers were deposited at 650 °C followed by deposition of amorphous layers at 100–400 °C. Subsequent solid phase epitaxial regrowth of these layers has been achieved at 650 °C.

Height-diameter equations for seventeen tree species in southwest Oregon (1987)

Equations for predicting total height as a function of diameter at breast height are presented for 17 tree species from southwest Oregon. Because basal area and site index often influence tree height, additional equations are presented which may include either or both of these as independent variables. Equation coefficients were estimated with weighted nonlinear regression techniques and validated on an independent data set. When tree heights are not measured in stand exams or inventories, these equations are useful for estimating height or, indirectly, height growth.
A Review on Automated Brain Tumor Detection and Segmentation from MRI of Brain (2013)

Tumor segmentation from magnetic resonance imaging (MRI) data is an important but time consuming manual task performed by medical experts. Automating this process is a challenging task because of the high diversity in the appearance of tumor tissues among different patients and in many cases similarity with the normal tissues. MRI is an advanced medical imaging technique providing rich information about the human soft-tissue anatomy. There are different brain tumor detection and segmentation methods to detect and segment a brain tumor from MRI images. These detection and segmentation approaches are reviewed with an importance placed on enlightening the advantages and drawbacks of these methods for brain tumor detection and segmentation. The use of MRI image detection and segmentation in different procedures are also described. Here a brief review of different segmentation for detection of brain tumor from MRI of brain has been discussed.
A fast method for finding the exact N-best hypotheses for multitarget tracking (1993)

The necessity for multiple hypothesis tracking (MHT) is recognized throughout the SDI tracking community. However, implementations of MHT techniques have required enormous amounts of computer time and memory. An efficient method of measurement-to-target association that makes MHT practical for the first time is presented. The method finds the exact N-best feasible hypotheses directly from a sequence of linear assignment problem solutions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
