A second order expansion of the eigenvalues of a parameter perturbation of Hermitian matrices is derived using matrix decomposition methods. The method developed is then applied to give a novel proof of a second order approximation of the eigenvalues of a global perturbation of Hermitian matrices first described by M. Carlsson. The result generalizes an approximation given by G.W Stewart which tre
Cardiac arrest causes an abrupt cessation of circulation, which rapidly leads to global ischaemia and hypoxia. Immediate and competent care is vital, and even when the circulation has been restored, there is a profound risk of patients never regaining consciousness due to hypoxic–ischaemic brain injury, or death due recurrent cardiac arrest or multiorgan failure. The complex pattern of symptoms se
Most clinical laboratories measure total magnesium (tMg) which includes both the ionized (iMg) and bound forms. Only the ionized component is biologically active, and it may be influenced by acid-base status, plasma protein concentrations and electrolyte disturbances, potentially altering how well tMg reflects iMg. This multicenter observational study evaluated the relationship between tMg and iMg
Background: Swedish nationwide family and cancer data offer the largest global resource for study of familial cancer. We focus here on familial risks in prostate cancer (PC) with questions on risk in individuals from families of multiple affected members and association of familial risk with metastatic disease and survival. Methods: Familial relative risk of PC was estimated using standardized inc
While circular economy (CE) discourse emphasises technology-driven solutions and formal systems, cities in the Global South rely on grassroots waste workers (WWs) in the informal sector, who perform essential circular functions through waste collection, sorting, and recycling. In Delhi, informal WWs contribute substantially to material recovery and fill gaps left by formal solid waste management (
Objectives: Panax ginseng (P. ginseng, C.A. Meyer) is suggested to improve blood glucose regulation, but evidence remains inconsistent. We examined whether consuming P. ginseng as a preload before a carbohydrate-rich meal modulates postprandial glucose and insulin responses. Methods: In a randomized, double-blind, crossover trial, 22 healthy middle-aged adults consumed P. ginseng tablets containin
We report a radical extension of magnetic-resonance spectroscopy to the Terahertz (THz) spectral range by complete polarization-resolved measurement of the linear electromagnetic response of nuclear and electron spin associated magnetic resonance using principles of ellipsometry at high magnetic fields. This new method permits us to accurately test existing models and leads to discovery of new phy
The CRISPR/Cas9 system has emerged as a transformative tool in genome editing, playing a pivotal role in enabling precise genetic engineering. Achieving high on-target efficiency while minimizing off-target activity is critical for translating CRISPR/Cas9 into reliable experimental and therapeutic applications. Conventional off-target detection methods are labor-intensive and cost-prohibitive, lim
The glymphatic system facilitates cerebrospinal fluid (CSF)-interstitial fluid exchange and plays a key role in solute clearance and neurophysiological homeostasis. While dysfunction of this system has been shown in traumatic brain injury, stroke, meningitis, idiopathic normal pressure hydrocephalus and neurodegenerative diseases, direct measurement of glymphatic transport in humans remains elusiv
BACKGROUND AND OBJECTIVE: Achieving adequate concentrations of beta-lactam antibiotics in patients with severe infections is challenging, and therefore therapeutic drug monitoring (TDM) would be optimal for guiding beta-lactam dosing, but is often limited by availability. UV/VIS spectrophotometry can quantify drug levels in saline, and if those levels truly reflect plasma concentrations, it could
Who benefited from agricultural commercialization in colonial Africa? Using social tables for three African economies, we identify a small group of rural capitalists who captured disproportionate gains. We demonstrate how their strategies of accumulation varied across contexts and shaped divergent and often unequal development trajectories.
Municipalities shoulder the burden of creating business-friendly environments – managing infrastructure, navigating public resistance, and investing countless hours in smoothing the path for economic development. Yet, the rewards often flow elsewhere. Local taxes on economic activity offer a powerful solution. While a thriving local economy boosts budgets, different taxes shape municipal decision-
Background: This study evaluates deep learning (DL) using gene expression (GEX) and preoperatively available clinical data (PreopClinic) to predict sentinel lymph node macro-metastasis (SLNM), and explores their potential for guiding axillary surgery de-escalation and supporting prognostic assessment.Methods: We retrospectively included 6,836 clinically node-negative (cN0) T1-T2 patients with inva
