Phosphatocopids are a group of small extinct marine crustaceans, which occur widespread in Cambrian dysoxic benthic lithofacies. Whereas the anatomy of the earliest ontogenetic stages of phosphatocopids, from the head larva with four pairs of appendages onward, is well documented, that of more advanced or adult growth stages has remained almost unknown (except for the external shields). Here we de
Photoionization with a single photon is one of the fundamental processes in nature, in which one electron is ripped away from its atom. Traditionally studied in the energy domain, this process was believed to be instantaneous, but recent advances in the production of attosecond pulses (1 as 10−18 s) in the eXtreme UltraViolet (XUV) have renewed interest in understanding the temporal aspects of ele
Objectives To compare short-term cardiovascular (CV) outcome in type 2 diabetes (T2D) patients without ischaemic heart disease (IHD), with IHD but no prior myocardial infarction (MI), and those with prior MI; and assess the impact on risk of age when initiating first-time glucose-lowering drug (GLD). Design Cohort study linking morbidity, mortality and medication data from Swedish national registr
Low frequency impact sound insulation is a challenging task in wooden buildings. Low frequency prediction tools are needed to access the dynamic behavior of a wooden floor in an early design phase to ultimately reduce the low frequency impact noise. However, due to the complexity of wood and different structural details, accurate vibration predictions of wood structures are difficult to attain. Me
Background: We have previously reported quantitative exposure-response relationships between physical exposures recorded by technical methods, and complaints and diagnoses in the neck/shoulders, and the elbows/hands, based on group data. In the present study the number of workers was doubled, and information on individual factors, and psychosocial working conditions was used. Relationships between
New techniques capable of accessing ultrafast demagnetisation processes on the sub-10 femtosecond timescale are presently in great demand. Achieving a high temporal resolution in pump-probe time-resolved experiments is very important for studying ultrafast processes in matter, providing an ideal platform for understanding interaction mechanisms, such as the spin-orbit coupling, the exchange intera
Background: It has been suggested that smoking is associated with reduced risk of knee osteoarthritis (OA). However, supplementary studies are needed to further investigate any such potential association. Thus, our aim was to examine the relationship between smoking and early or more established knee OA in a cohort of relatively young patients with meniscal tears. Methods: This cross-sectional stu
In this study, we investigate the molecular structural characteristics of organic remains in various cellular organelles from a 180 Ma Jurassic royal fern belonging to the Osmundaceae family of ferns, and compare their carbon isotopic compositions to a now-living species of royal fern (Osmunda regalis). We discovered molecular structural variations indicated by Raman and infrared spectral paramet
The generation of XUV supercontinua is of high interest for different applications in that region of the spectrum, such as spectral interferometry and spectroscopy. In high-order harmonic generation (HHG) supercontinua are usually obtained only when a single attosecond pulse is produced, but this implies gating techniques or sub-3-fs IR driving pulses. In this work we demonstrate a new approach fo
Extreme climate events occur more frequently and stronger in the future due to climate change. Maintaining the energy security during extreme conditions is essential to reduce the impacts of extreme climate and avoid disasters. Resilient design of the energy system to resist against extreme climate events are investigated considering four scenarios, namely, typical demand (TD), extreme demand (ED)
The IEEE Std. P1687.1 is exploring alternatives to IEEE Std. 1149.1 test access port for accessing IEEE Std. 1687 scan networks of instruments. In this paper, we investigate the use of universal asynchronous receiver-transmitter (UART) to access IEEE Std. 1687 networks. We have developed a protocol to describe scan-data transported over UART and a hardware component to translate (retarget) informa
A bioassay screening against protozoa parasites of several Tacana medicinal plants gave Hyptis brevipes (Id'ene eidhue), traditionally used as decoction for intestinal parasites, as the most active extract. In this work we did a bioguided isolation of active constituents found in leaves. Structure elucidation was carried out by NMR spectroscopy and MS spectrometry analyses. Active constituents sho
Background: The gracilis tendon is commonly used as an autograft to reconstruct torn tendons or ligaments in many parts of the body. Little is known about the subjective and functional outcome after gracilis tendon harvest. The aim of this study was to evaluate the outcome of the donor leg in patients undergoing such surgery. Methods: Patients with chronic acromioclavicular joint dislocations unde
ObjectivesThis study aimed to investigate the rate of dizziness and occurrence of benign paroxysmal positional vertigo in the elderly by physical examination in those reporting dizziness symptoms when lying down or turning over in bed.MethodsA total of 498 people, aged 70-85 years, were asked to complete a questionnaire regarding dizziness symptoms. Subjects answering that they became dizzy in bed
Background: Tendons are a crucial component of the musculoskeletal system and responsible for transmission forces derived from muscle to bone. Patients with tendon injuries are often observed with decreased collagen production and matrix degeneration, and healing of tendon injuries remains a challenge as a result of limited understanding of tendon biology. Recent studies highlight the contribution
Background: The impact of perioperative care interventions on postreconstructive complications and short-term colorectal outcome in patients with anorectal malformation (ARM) type rectovestibular fistula is unknown. Methods: An ARM-Net consortium multicenter retrospective cohort study was performed including 165 patients with a rectovestibular fistula. Patient characteristics, perioperative care i
The current monolithic and lengthy scheme behind the standardization and the design of new video coding standards is becoming inappropriate to satisfy the dynamism and changing needs of the video coding community. Such a scheme and specification formalism do not enable designers to exploit the clear commonalities between the different codecs, neither at the level of the specification nor at the le
