Mapping inundation extents in Poyang Lake area using Sentinel-1 data and transformer-based change detection method

Accurate and timely mapping of inundation extents during flood periods is essential for disaster evaluation and development of rescue strategies. With unique advantages over the optical sensors (e.g., little effect of clouds, and observations at day and night), Synthetic aperture radar (SAR) sensors provide an important data source for mapping inundation, particularly during flood periods. Freely

Object Detector Differences when Using Synthetic and Real Training Data

To train well-performing generalizing neural networks, sufficiently large and diverse datasets are needed. Collecting data while adhering to privacy legislation becomes increasingly difficult and annotating these large datasets is both a resource-heavy and time-consuming task. An approach to overcome these difficulties is to use synthetic data since it is inherently scalable and can be automatical

A federated approach to identify women with early-stage cervical cancer at low risk of lymph node metastases

Objective: Lymph node metastases (pN+) in presumed early-stage cervical cancer negatively impact prognosis. Using federated learning, we aimed to develop a tool to identify a group of women at low risk of pN+, to guide the shared decision-making process concerning the extent of lymph node dissection. Methods: Women with cervical cancer between 2005 and 2020 were identified retrospectively from pop

The two-state impasse in Israel/Palestine : The EU caught between egalitarian norms and expansionist realpolitik

In recent years, many academics as well as local actors have started to question the feasibility of a two-state solution for Israeland Palestine. Increased Israeli unilateralism, expansionism as well as weak Palestinian institutions has instead pointed toward a‘one-state-reality’ where Israel is in de facto control over all lands. This in turn reveals a paradox, where internationalpolicymakers, mo

Windstorm impacts on European forest-related systems: an interdisciplinary perspective

Windstorms are considered the main disturbing abiotic agent in European forests. They affect a multiplicity of forest-related dimensions, such as forest ecology, forest operations, geomorphology, economy, and socio-cultural aspects. Due to the complex dynamics set off by windstorms, the design of post-windstorm forest management should be characterized by an interdisciplinary approach able to addr

A Psychometric Evaluation of the Expanded Version of the Inventory of Depression and Anxiety Symptoms (IDAS-II) in Children and Adolescents

The expanded version of the Inventory of Depression and Anxiety Symptoms (IDAS-II) is a self-report measure of 18 empirically derived internalizing symptom dimensions. The measure has shown good psychometric properties in adults but has never been evaluated in children and adolescents. A Swedish version of the IDAS-II was administered to 633 children and adolescents (Mage =16.6 [SD = 2.0]) and 203

From genes to blooms : Diversity in microcystin phenotypes and mcy biosynthesis genes in the cyanobacterium Microcystis

Cyanobakterier är urgamla prokaryoter, som finns i en mängd olika livsmiljöer över hela världen. Deras förmåga att utföra fotosyntes (det vill säga att använda solljus, vatten och koldioxid för att producera syre- och kolhydrater) gör dem till viktiga primära producenter, och tillsammans med andra växtplankton utgör de basen för akvatiska näringsvävar.Vid optimala tillväxtförhållandena kan populatCyanobacterial blooms are increasing in occurrence and frequency world-wide, mainly due to eutrophication and increased water temperatures. In freshwater, Microcystis is one of the most common bloom-forming genera, renowned for producing the toxin microcystin which is harmful to humans and other mammals. The ability of Microcystis strains to produce microcystins is largely due to the presence or a

Activism online : exploring how crises are communicated visually in activism campaigns

During the past years, activist movements have increasingly turned to social media to raise awareness and critically discuss current development and future scenarios. As a contribution to the discussion of new social movements and activism in the digital age, this study aims to explore and critically discuss how environmental risks and crisis are visually communicated in activism campaigns on Inst

Data-driven microscopy: placing high-fidelity data in a population-wide context

Mikroskopi är idag ett fundamentalt verktyg inom forskning, där det tillåter oss att skåda in och utforska våra prover i hög detalj. Mycket utav utvecklingen av nya mikroskopimetoder har strävat efter att öka den detaljnivå vi kan uppnå. Samtidigt har utvecklingen inom hårdvara, med tillgång till bättre och mer kraftfulla instrument, lett till utveckligen av metoder där fokuset är att studera en h

Petrochemicals and climate change: Powerful fossil fuel lock-ins and interventions for transformative change

With the risk of climate breakdown, pressure is increasing for all sectors of the economy to break with fossil fuel dependence and reduce greenhouse gas emissions. In this context, the chemical industry requires more focused attention as it uses more fossil-fuel based energy than any other industry and the production of chemicals is associated with very large emissions. Beyond the climate crisis,

Sustained delivery of a heterodimer bone morphogenetic protein-2/7 via a collagen hydroxyapatite scaffold accelerates and improves critical femoral defect healing

Despite the glimmer of hope provided by the discovery and commercialization of bone morphogenetic protein-2 (BMP-2) as a bone graft substitute, side effects related to the use of supraphysiological doses have hindered its clinical usage. In this study, we compared the osteoinductive potential of BMP-2 homodimer with a heterodimer of BMP-2/7, both delivered via a collagen-hydroxyapatite (CHA) scaff

The Meridian S03E02 : The Hunt for Dark Matter

We are on a hunt for the invisible in this second episode of the third season of The Meridian. Ruth Pöttgen is a senior lecturer at the Department of Physics where she is studying fundamental particles. She is especially interested in finding that mysterious and elusive Dark Matter particle.In this third season we are also including some Cosmic Curiosities. These are some ideas, events or trivia f

Sardex: A digital business-to-business currency

The case presents Sardex, a local complementary currency in the Mediterranean island of Sardinia designed to alleviate the economic hardships brought by the economic crisis of 2008.The reader gets an insight into the economic contexts of these currencies, the functioning of one of its most common designs (mutual credit systems or LETS), as well as the work of embedding these local currencies into
