Polyp Segmentation of Colonoscopy Images by Exploring the Uncertain Areas

Colorectal cancer is one of the leading causes of death worldwide. Polyps are early symptoms of colorectal cancer and prone to malignant transformation. Polyp segmentation of colonoscopy images can help diagnosis. However, existing studies on polyp segmentation of colonoscopy images face two main difficulties: blurry polyp boundaries, close resemblances between polyps and surrounding tissues. The

The surface composition of amino acid - halide salt solutions is pH-dependent

In atmospheric aerosol particles, the chemical surface composition governs both heterogenous chemical reactions with gas-phase species and the ability to act as nuclei for cloud droplets. The pH in aerosol particles is expected to affect these properties, but it is very challenging to measure the pH in individual droplets, precluding the investigation of its influence on the particle's surface com

Compositions for reprogramming cells into dendritic cells or antigen presenting cells, methods and uses thereof.

The present disclosure relates to compositions, nucleic acid constructs, methods and kits thereof for cell induction or reprogramming cells to the dendritic cell state or antigen presenting cell state, based, in part, on the surprisingly effect described herein of novel use and combinations of transcription factors that permit induction or reprogramming of differentiated or undifferentiated cells

Review: Representing Islam: Hip-Hop of the September 11 Generation

The book Representing Islam: Hip-Hop of the September 11 Generation (2020) by Kamaludeen Mohmed Nasir explores the entangled relationship between Islam and hip-hop. The book centers around Muslim hip-hop artists affected by the war on terror and the long-term consequences of the 9/11 attacks; increased surveillance, a securitization of Islam, and an amplified islamophobia, not only in the United S

The Kinetic Energy of PAH Dication and Trication Dissociation Determined by Recoil-Frame Covariance Map Imaging

We investigated the dissociation of dications and trications of three polycyclic aromatic hydrocarbons (PAHs), fluorene, phenanthrene, and pyrene. PAHs are a family of molecules ubiquitous in space and involved in much of the chemistry of the interstellar medium. In our experiments, ions are formed by interaction with 30.3 nm extreme ultraviolet (XUV) photons, and their velocity map images are rec

Swedish conditions? Characteristics of locations the Swedish Police label as vulnerable

Deprived neighborhoods in Sweden in which criminal networks have a negative impact on local residents are labeled as “vulnerable neighborhoods” by the police. The method used by the police to classify such neighborhoods is largely based on perceptions, which raises issues of subjectivity and potential biases. The present study explores the characteristics of such neighborhoods based on registry da

Vem bestämmer hur staden ska bli?

Kapitlet behandlar medskapandets process i stadsutveckling. Bidraget beskriver utifrån olika aktörers perspektiv - tjänstepersoner, chefer och politiker - hur medskapandeprocesser inte bara handlar om relationen till invånarna, utan mellan olika aktörer inom en kommun. Kapitlet argumenterar för att medskapande inte endast kan handla om vilka tekniker som används för att skapa relationer med invåna

Risk stratification score screening for infective endocarditis in patients with Gram-positive bacteraemia

Background: A feared cause of bacteraemia with Gram-positives is infective endocarditis. Risk stratification scores can aid clinicians in determining the risk of endocarditis. Six proposed scores for the use in bacteraemia; Staphylococcus aureus (PREDICT, VIRSTA, POSITIVE), non-β-haemolytic streptococci (HANDOC) and Enterococcus faecalis (NOVA, DENOVA) were validated for predictive ability and the

A complex and demanding situation – Midwifery preceptors and midwifery students’ experiences of teaching and learning prevention of severe perineal trauma

BackgroundMany high-income countries have seen an increase in severe perineal trauma. Teaching strategies and conditions for learning during the active second stage of labour are scarcely described.AimTo describe midwifery preceptors and midwifery students’ experiences’ of teaching and learning how to manage the second stage of labour, with the specific aim of preventing severe perineal trauma.Met

A more efficient braking system for heavy vehicles

Pneumatiska bromssystem i tunga fordon är oeffektiva ur energiperspektiv, artikeln beskriver mätningar som jämför pneumatiska och elektromekaniska bromssystem för en batterielektrisk buss.Electric powertrains increase efficiency in road vehicles and enable zero tailpipe emissions, but introduce practical limitations in on board energy storage capacity, due to the low energy density in battery systems when compared with chemical fuels in tanks. The increased powertrain efficiency and lower on-board energy storage levels place focus on other energy consumers in the vehicle system, su
