The autonomic nervous system (ANS) is an important factor in cardiac arrhythmia, and information about ANS activity during atrial fibrillation (AF) may contribute to personalized treatment. In this study we aim to quantify respiratory modulation in the f-wave frequency trend from resting ECG. First, an f-wave signal is extracted from the ECG by QRST cancelation. Second, an f-wave model is fitted t

Proteogenomic approaches have enabled the generat̲ion of novel information levels when compared to single omics studies although burdened by extensive experimental efforts. Here, we improved a data-independent acquisition mass spectrometry proteogenomic workflow to reveal distinct molecular features related to mammographic appearances in breast cancer. Our results reveal splicing processes detecta

The global antimicrobial drug resistance crisis requires urgency in searching for more effective broad-spectrum antimicrobial drugs. Here, we present a complete circular genome sequence and a plasmid of an antimicrobial-producing isolate, Bacillus velezensis strain Sam8H1, from the Makgadikgadi saltpans in Botswana. Bioinformatic analyses revealed 12 putative secondary metabolite biosynthetic gene

Background: The management of cancer-related pain relies on access to opioids. When regular opioids are not tolerated, or are insufficient, methadone is an affordable and effective analgesic. Aim: The aim of the project was to describe the pattern of use and clinical experience of methadone in pediatric cancer pain at a governmental cancer hospital in Hyderabad, one of the four Indian cancer cente

Airway basal cells are crucial for regeneration of the human lung airway epithelium, and are thought to be important contributors to Chronic Obstructive Pulmonary Disease (COPD) and other lung disorders. In order to reveal how basal cells contribute to disease, and to discover novel therapeutic targets, these basal cells need to be further characterized. In this study, we optimized a flow cytometr

All kinds of public policies are being proposed to address our climate and sustainability challenges, for example, emission standards, substance bans, aviation taxes, energy efficiency labels, and even communication campaigns. However, global carbon dioxide emissions keep going up! Are these policies working? Under what circumstance? And, at what cost to other systems in society? To answer these q

Arctic archaeologists generally accept that Dorset Paleo-Inuit (Tuniit) (c. 800 BC-1300 AD) toolkits exhibit high levels of typological uniformity across Arctic Canada and Greenland. This understanding implies that the artifacts were likely produced according to a standardized set of practices that were somehow ÷einforced over time and shared across the isolated sites and communities inhabiting th

Particulate radioactivity, a characteristic of particulate matter, is primarily determined by the abundance of radionuclides that are bound to airborne particulates. Exposure to high levels of particulate radioactivity has been associated with negative health outcomes. However, there are currently no spatially and temporally resolved particulate radioactivity data for exposure assessment purposes.

Sleep has evolved as a universal core function to allow for restorative biological processes. Detailed knowledge of metabolic changes necessary for the sleep state in the brain is missing. Herein, we have performed an in-depth metabolic analysis of four mouse brain regions and uncovered region-specific circadian variations. Metabolites linked to oxidative stress were altered during sleep including

Background Recently there has been increased interest in a possible association between mast cell activation (MCA) disorder and postural orthostatic tachycardia syndrome (POTS). This study examined the frequency with which symptoms and laboratory findings suggesting MCA disorder occurred in patients diagnosed with POTS. Methods and Results Data were obtained from patients in whom symptoms and orth

Phase retrieval is a numerical procedure concerned with the recovery of a complex-valued signal from measurements of its amplitude. We describe a generalization of this method for multi-wavelength data acquired in a coherent diffractive imaging experiment. It exploits the wavelength-dependent scaling of the support domain to recover separate reconstructions for each wavelength, providing new possi

The raw material tier in companies’ supply chains can be a hotspot for sustainability issues like deforestation and resulting legal, reputational, financial and operational risks – yet companies’ supply chain management efforts as well as research on sustainable supply chain management still focus on direct suppliers due to poor upstream transparency. With technical progress, remote sensing and sa

Patterns of variation and the structuring of diversity in seed phenotype and allozymes were investigated in Sweden Gypsophila fastigiata, a perennial herb with a disjunct ‘Late Glacial relict’ distribution in eastern and northern Europe. The overall patterns of variation in allozymes and seed morphology are congruent and are significantly correlated with geographic distance. However, most of the c

Airborne observations conducted during the Northeast Monsoon onset as part of the Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX 2011) are used to link the activation properties of aerosols with the observed cloud microphysics. This study illustrates the significant spatial variability in the aerosol spectrum, cloud condensation nuclei (CCN) activation characteristics,
