Multivariable prediction models of caries increment : a systematic review and critical appraisal

Background: Multivariable prediction models are used in oral health care to identify individuals with an increased likelihood of caries increment. The outcomes of the models should help to manage individualized interventions and to determine the periodicity of service. The objective was to review and critically appraise studies of multivariable prediction models of caries increment. Methods: Longi

An ultralow-temperature cascade refrigeration unit with natural refrigerant pair R290-R170 : Performance evaluation under different ambient and freezing temperatures

The global demand for ultralow-temperature (ULT) refrigeration units gets greatly promoted, for storage, transportation, and distribution of COVID-19 vaccines. In this work, a ULT freezer is developed with a cascade refrigeration system (CRS) utilizing environmentally friendly refrigerants R290 and R170. The performance of the ULT freezer is experimentally evaluated under different ambient tempera

The rise and fall of the Malvinoxhosan (Malvinokaffric) bioregion in South Africa : Evidence for Early-Middle Devonian biocrises at the South Pole

Global reconstructions, inclusive of environments and ecosystems, and biodiversity counts for the Devonian Period are often done so at the expense of high latitude regions given a historical lack of data presented from these areas. This has bearing on the recognition of biocrises (events marked by extinctions and faunal turnovers) at high latitudes as well as their controls and potential correlati

To what extent are greenhouse-gas emissions offset by trees in a Sahelian silvopastoral system?

To assess the extent to which trees in a semi-arid silvopastoral system (SPS) can offset the greenhouse-gas (GHG) emissions of the system's livestock, this study used two process-based models (STEP-GENDEC-N2O and DynACof) to simulate 9 years of agricultural activity and resulting emissions in a SPS that has been operating in sahelian Senegal. STEP-GENDEC-N2O simulated soil N2O and CO2 fluxes, plus

Diffusion MRI with free gradient waveforms on a high-performance gradient system : Probing restriction and exchange in the human brain

The dependence of the diffusion MRI signal on the diffusion time carries signatures of restricted diffusion and exchange. Here we seek to highlight these signatures in the human brain by performing experiments using free gradient waveforms designed to be selectively sensitive to the two effects. We examine six healthy volunteers using both strong and ultra-strong gradients (80, 200 and 300 mT/m).

Assessing the risks and opportunities posed by AI-enhanced influence operations on social media

Large language models (LLMs) like GPT-4 have the potential to dramatically change the landscape of influence operations. They can generate persuasive, tailored content at scale, making campaigns using falsified content, such as disinformation and fake accounts, easier to produce. Advances in self-hosted open-source models have meant that adversaries can evade content moderation and security checks

Dude, Where's My Car? Cellular Navigation for Autonomous Driving

Position and direction estimation is useful for numerous engineering applications for commercial, scientific, and military purposes. Technology that fuses observations of signals broadcast by Global Navigational Satellite Systems (GNSS) with inertial measurements is standard for electronic devices, but this requires at least a periodically unobstructed view of the sky to perform reliably. This has

Skapa Demokrati

I Skapa demokrati utforskar deltagarna vilka utmaningar man kan stöta på när man försöker bygga en demokrati från grunden. Projektet är framtaget i samarbete med forskningsstiftelsen Institutet för framtidsstudier och ingår forsknings- och utvecklingsarbetet kring nya sceniska berättarformat på Teaterhögskolan i Malmö.

Measurement of the radius dependence of charged-particle jet suppression in Pb–Pb collisions at sNN=5.02TeV

The ALICE Collaboration reports a differential measurement of inclusive jet suppression using pp and Pb–Pb collision data at a center-of-mass energy per nucleon–nucleon collision sNN=5.02 TeV. Charged-particle jets are reconstructed using the anti-kT algorithm with resolution parameters R=0.2, 0.3, 0.4, 0.5, and 0.6 in pp collisions and R=0.2, 0.4, 0.6 in central (0–10%), semi-central (30–50%), an

Observation of WZγ Production in pp Collisions at sqrt[s]=13 TeV with the ATLAS Detector

This Letter reports the observation of WZγ production and a measurement of its cross section using 140.1±1.2 fb^{-1} of proton-proton collision data recorded at a center-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. The WZγ production cross section, with both the W and Z bosons decaying leptonically, pp→WZγ→ℓ^{'}^{±}νℓ^{+}ℓ^{-}γ (ℓ^{(^{'})}=e, μ), is measured in a fi

Early management of adult traumatic spinal cord injury in patients with polytrauma: a consensus and clinical recommendations jointly developed by the World Society of Emergency Surgery (WSES) & the European Association of Neurosurgical Societies (EANS)

Background: The early management of polytrauma patients with traumatic spinal cord injury (tSCI) is a major challenge. Sparse data is available to provide optimal care in this scenario and worldwide variability in clinical practice has been documented in recent studies. Methods: A multidisciplinary consensus panel of physicians selected for their established clinical and scientific expertise in th

Evidence for the Higgs Boson Decay to a Z Boson and a Photon at the LHC

The first evidence for the Higgs boson decay to a Z boson and a photon is presented, with a statistical significance of 3.4 standard deviations. The result is derived from a combined analysis of the searches performed by the ATLAS and CMS Collaborations with proton-proton collision datasets collected at the CERN Large Hadron Collider (LHC) from 2015 to 2018. These correspond to integrated luminosi

Öva Demokrati

Projektet är framtaget i samarbete med forskningsstiftelsen Institutet för framtidsstudier och ingår forsknings- och utvecklingsarbetet kring nya sceniska berättarformat på Teaterhögskolan i Malmö.

Against Book Enclosures : Moving Towards More Diverse, Humane and Accessible Book Publishing

Matthew Gandy's Commentary in Area (2023) criticised the decision of the national funder UKRI to mandate that all books resulting from the research that it funds must be published open access (OA) from 2024. This raises many issues of importance to geographers. We argue that scholars in the discipline need to fight for affordable and ethically produced OA books, not ‘legacy’ modes of publishing. I

Data-driven precision determination of the material budget in ALICE

The knowledge of the material budget with a high precision is fundamental for measurements of direct photon production using the photon conversion method due to its direct impact on the total systematic uncertainty. Moreover, it influences many aspects of the charged-particle reconstruction performance. In this article, two procedures to determine data-driven corrections to the material-budget des

Creating Democracy

Vi gjorde en engelska variant av Skapa demokrati som spelades på Svenska Ambassaden, Georgetown University och en skolklass i Whittier Elementary SchoolWorkshopen i Washington DC är en del av projektet Expanding Minds – together, ett samarbete mellan Institutet för Framtidsstudier, Kulturhuset Stadsteatern och ABF med stöd av Postkodstiftelsen. Syftet är att, med kulturens redskap och medborgares erfarenheter, skapa bryggor mellan forskning och allmänhet och på så sätt förnya demokratisk interaktion och organisering.

Improving breast cancer screening with artificial intelligence

Introduction: The current standard method for breast cancer screening is digital mammography (DM). Digital breast tomosynthesis (DBT) can detect more cancers but is more resource-demanding, not the least due to a more time-consuming reading, which hinders the implementation in screening. Artificial intelligence (AI) might open possibilities to overcome this, but different potential ways of using A
