Observation of Genuine High-dimensional Multi-partite Non-locality in Entangled Photon States

Quantum information science has leaped forward with the exploration of high-dimensional quantum systems, offering greater potential than traditional qubits in quantum communication and quantum computing. To advance the field of high-dimensional quantum technology, a significant effort is underway to progressively enhance the entanglement dimension between two particles. An alternative effective st

The Mitochondrial Signature for Predicting Outcome of Early-Stage Breast Cancer by Machine Learning

INTRODUCTION: Breast cancer, a leading female cancer worldwide, can be influenced by mitochondrial dysfunction. Dysregulation of mitochondria by the nuclear genome may cause breast cancer initiation and progression. However, the comprehensive investigation of mitochondrial-related genes as prognostic marker for the overall survival of early-stage breast cancer patients is still limited.METHODS: To

Postoperative leukopenia after cytoreductive surgery and hypertherm intraperitoneal chemotherapy for colorectal carcinomatosis- causes and implication on outcomes in a population-based study

BACKGROUND: Leukocytes have been reported to have tumor stimulating effects in colorectal cancer, among other malignancies. In line with this, earlier research has shown improved disease-free survival in patients with postoperative neutropenia compared to non-neutropenic patients following cytoreductive surgery (CRS) and hypertherm intraperitoneal chemotherapy (HIPEC).AIM: To evaluate the impact o

Global Methane Budget 2000-2020

Understanding and quantifying the global methane (CH4) budget is important for assessing realistic pathways to mitigate climate change. CH4 is the second most important human-influenced greenhouse gas in terms of climate forcing after carbon dioxide (CO2), and both emissions and atmospheric concentrations of CH4 have continued to increase since 2007 after a temporary pause. The relative importance

Decipherment of Historical Manuscripts with Unknown or Rare Writings : The DESCRYPT Project

We present a newly funded research program, DESCRYPT, aimed at deciphering and analyzing historical texts with rare or unknown scripts. The project leverages advancements in computational linguistics, artificial intelligence (AI), and image processing, alongside traditional philological methods, to develop innovative tools for transcription, recognition, and interpretation of historical writings w

What psi research can -and cannot- say about 'mind beyond the brain'

Research on parapsychological (psi) phenomena is very relevant in the discussion of whether mental processes might go beyond the known limits of brain capacities. Nonetheless, most scientific and philosophical discussions of mind-brain relations do not even mention such research, despite showing similar empirical robustness to that of acknowledged mainstream research in psychology, medicine, and t

Fusion Imaging in Endovascular Thrombectomy for Acute Ischemic Stroke

BACKGROUNDRecanalization sometimes fails during endovascular thrombectomy due to target vessel access failure. Two‐dimensional/3‐dimensional fusion imaging in the Siemens ARTIS Icono biplane platform may facilitate access by fusing the preoperative computed tomography angiography with procedural imaging. This observational study aimed to evaluate vascular access, success rates, and procedure times

Outcomes After Thrombectomy for Primary and Secondary Medium Vessel MCA Occlusions : a Nationwide Registry Study

BACKGROUND: Medium vessel occlusions (MeVO) can be either isolated events (primary), or secondary to thrombus migration from a large vessel occlusion to a medium-sized vessel. Outcomes following endovascular thrombectomy (EVT) in the middle cerebral artery (MCA) may differ between primary and secondary MeVOs. This study aimed to assess the association between primary/secondary MeVOs and clinical o

Modern handläggning av intracerebralt hematom

Intracerebral hemorrhage (ICH) carries the highest mortality and morbidity of all stroke types. Although small vessel disease accounts for the majority of ICH, there is a broad spectrum of other etiologies. Modern imaging techniques are a cornerstone of the work-up process. The goals of acute management are to prevent hematoma expansion, stabilize and prevent failure of vital functions, and establ

The impact of comorbidity burden on outcomes following endovascular thrombectomy for acute ischemic stroke : A nationwide prospective observational study

Introduction: Patients with substantial comorbidity burden are underrepresented in clinical trials on endovascular thrombectomy (EVT), despite being common in clinical routine care. Therefore, analysis of observational data is needed to evaluate how increasing comorbidity burden affects procedural success rate, complication rate, and clinical outcome following EVT. Patients and methods: We conduct

The effect of intravenous ferric carboxymaltose on health-related quality of life in iron-deficient patients with acute heart failure : the results of the AFFIRM-AHF study

AIMS: Patients with heart failure (HF) and iron deficiency experience poor health-related quality of life (HRQoL). We evaluated the impact of intravenous (IV) ferric carboxymaltose (FCM) vs. placebo on HRQoL for the AFFIRM-AHF population.METHODS AND RESULTS: The baseline 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12), which was completed for 1058 (535 and 523) patients in the FCM and p

Long-term prognosis after coronary bifurcation PCI-A nationwide observational study

BACKGROUND: Long-term outcomes of percutaneous coronary intervention (PCI) for bifurcation lesions are underexplored. We investigated long-term PCI outcomes for proximal LAD bifurcation lesions involving D1.METHODS: Using Swedish registries, we included all patients undergoing LAD-D1 bifurcation PCI with drug-eluting stents between 2010 and 2020. Patients were stratified into two groups: simple PC

Practice patterns and percutaneous coronary intervention outcomes : a comparison between Sweden and the US

AIMS: Comparisons of international practice patterns and their impact on percutaneous coronary intervention (PCI) outcomes are lacking. We compared temporal PCI trends between Sweden and a large university hospital system in the US.METHODS AND RESULTS: Data within the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) and the University of California San Diego Health internal National C

A reliable and objective method of measuring soft tissue changes in 2D photographs after distraction osteogenesis in individuals with CL/P

Pre-and postoperative photos to assess results are widely used in plastic and reconstructive surgery, for instance, in patients with cleft lip and palate (CL/P). Evaluations are often performed by assessment panels by viewing the photos. However, these are prone to be subjective. Measurements of soft tissues in photos could be an alternative method but have not been widely used so far. Some patien

Large-Eddy Simulation of Supersonic Combustion in a Mach 2 Cavity Model Scramjet Combustor

In this study, we report on reactive large-eddy simulations (LESs) of flow and combustion in the U.S. Air Force Research Laboratory Research Cell 19 cavity-based scramjet combustor. This case involves the combustion of ethylene that is injected into a cavity. It has previously been studied experimentally with multiple techniques, including particle image velocimetry, hyperspectral imagining, and l
