Co-Circulation of Leishmania Parasites and Phleboviruses in a Population of Sand Flies Collected in the South of Portugal

open access: yesTropical Medicine and Infectious Disease, 2023
In the Old World, phlebotomine sand flies from the genus Phlebotomus are implicated in the transmission of Leishmania spp. parasites (Kinetoplastida: Trypanosomatidae) and viruses belonging to the genus Phlebovirus (Bunyavirales: Phenuiviridae).

No-reference video quality measurement: added value of machine learning

open access: yesJournal of Electronic Imaging, 2015
Video quality measurement is an important component in the end-to-end video delivery chain. Video quality is, however, subjective, and thus, there will always be interobserver differences in the subjective opinion about the visual quality of the same video.

Modeling of Quality of Experience in No-Reference Model

open access: yesJournal of Telecommunications and Information Technology, 2017
The key objective of no-reference (NR) visual metrics is to predict the end-user experience concerning remotely delivered video content. Rapidly increasing demand for easily accessible, high quality video material makes it crucial for service providers ...

Identification of neutralizing epitopes on the D/A domain of the E2 glycoprotein of classical swine fever virus

open access: yesVirus Research, 2023
Classical swine fever virus (CSFV) shares high antigenic homology with other members of the genus Pestivirus. Because several pestivirus species can also infect swine, eliciting cross-reactive antibodies, it is important to define CSFV-specific epitopes ...

A no-reference perceptual blur metric [PDF]

open access: yesProceedings. International Conference on Image Processing, 2003
We present a no-reference blur metric for images and video. The blur metric is based on the analysis of the spread of the edges in an image. Its perceptual significance is validated through subjective experiments. The novel metric is near real-time, has low computational complexity and is shown to perform well over a range of image content.

Human Metapneumovirus: Etiological Agent of Severe Acute Respiratory Infections in Hospitalized and Deceased Patients with a Negative Diagnosis of Influenza

open access: yesPathogens, 2020
Human metapneumovirus (HMPV) is one of the four major viral pathogens associated with acute respiratory tract infections (ARI) and creates a substantial burden of disease, particularly in young children (<5 years) and older individuals (≥65 ...

Suggested Rational Considerations for ANA-IF and ENA-Profile Test Requisition: Clinical Manifestation, Gender, Pattern, and Titer of ANA-IF

open access: yesIndonesian Biomedical Journal, 2023
BACKGROUND: The anti-nuclear antibody immunofluorescence (ANA-IF) test is used for screening of autoantibody presence in patients with suspected autoimmune disease.

Collective electrodynamics I [PDF]

open access: yes, 1997
Standard results of electromagnetic theory are derived from the direct interaction of macroscopic quantum systems; the only assumptions used are the Einstein-deBroglie relations, the discrete nature of charge, the Green's function for the vector ...

No-Reference Stereo Image Quality Assessment by Learning Dictionaries and Color Visual Characteristics

open access: yesIEEE Access, 2019
Since a large proportion of the information that is received daily is in the form of images, a highly effective no-reference stereo image quality assessment (SIQA) method is desired.

Running coupling expansion for the renormalized $\phi^4_4$-trajectory from renormalization invariance [PDF]

open access: yes, 1996
We formulate a renormalized running coupling expansion for the $\beta$--function and the potential of the renormalized $\phi^4$--trajectory on four dimensional Euclidean space-time. Renormalization invariance is used as a first principle. No reference is
