The present study addresses the problem of respiratory rate estimation from ECG-derived respiration (EDR) signals during paroxysmal atrial fibrillation (AF). Novel signal-to-noise ratios between various components of the ECG including the influence of respiration, measured by QRS ensemble variance, the amplitude of fibrillatory waves (f-waves), and the QRS amplitude are introduced to characterize
In this paper a multimodal optical-resolution photoacoustic and fluorescence microscope in frequency domain is presented. Photoacoustic waves and modulated fluorescence are generated in chromophores by using a modulated diode laser. The photoacoustic waves, recorded with a hydrophone, and the fluorescence signals, acquired with an avalanche photodiode, are simultaneously measured using a lock-in t
In this study, the effect of axial heat conduction on thermal performance in a zigzag channel printed circuit heat exchanger (PCHE) with supercritical liquefied natural gas as the working fluid is studied by a numerical method under different conditions. The influence factors include Reynolds number, operating pressure, inlet temperatures of the cold side, and wall thermal conductivity. The result
In both economic and evolutionary theories of games, two general classes of evolution can be identified: dynamics based on myopic optimization and dynamics based on imitations or replications. The collective behavior of structured populations governed by these dynamics can vary significantly. Particularly in social dilemmas, myopic optimizations typically lead to Nash equilibrium payoffs that are
Membranous nephropathy (MN) is the most common cause of primary nephrotic syndrome among adults. The identification of phospholipase A2 receptor (PLA2R) as target antigen in most patients changed the management of MN dramatically, and provided a rationale for B-cell depleting agents such as rituximab. The efficacy of rituximab in inducing remission has been investigated in several studies, includi
Digital holography (DH) has been extensively applied in particle field measurements due to its promising ability to simultaneously provide the three-dimensional location and in-plane size of particles. Particle detection methods are crucial in hologram data processing to determine particle size and particle in-focus depth, which directly affect the measurement accuracy and robustness of DH. In thi
A numerical method is utilized in this paper to study the effects of varying divider inclination angle on the flow structure and heat transfer characteristics in a ribbed two-pass channel for Reynolds number varying from 10,000 to 50,000. The studied divider inclination angles are −3°,−2°,−1°,0°, +1°, +2° and +3°. The ribs have an orientating angle of 45°. The results show that the heat transfer i
The conservation community sorely lacks a global indicator of change in insect populations. Given widespread insect declines, addressing this gap is key for conservation and policy targets. We suggest that butterfly monitoring programs can serve as the foundation for an effective global network of insect monitoring. To assess this potential, we bring together an international consortium and calcul
The human side of corporate evaluation is frequently neglected in small firm and credit management research. However, it seems to matter both who is being evaluated, especially in smaller companies, and who is making the evaluation. A major reason is that individuals process information in different ways. The purpose of this paper is to develop a conceptual framework for the effects of human diffe
The use of charge balance functions in heavy-ion collision studies was initially proposed as a probe of delayed hadronization and two-stage quark production in these collisions. It later emerged that general balance functions can also serve as a probe of the diffusivity of light quarks as well as the evolution of the systems formed in heavy-ion collisions. In this work, we reexamine the formulatio
Forty-two chapters have been structured according to the toxicities in cancer entities, and the late effects and follow-up proposals have been discussed by European and American authors. Cancer diseases in children, adolescents and young adults are treated within specific treatment protocols and can produce different late effects that will have to be cared for by specific follow-up recommendations
Historiska aktörer är långt ifrån frånvarande i historieforskningen. Varje land och varje tidsepok har sin beskärda del av biografier över framstående vetenskapsmän, intellektuella och utbildningsreformatorer. Trots detta är det inte fel att hävda att de teoretiska strömningar som har satt sin prägel på historiska och sociologiska studier av kunskap sedan 1960-talet har betonat strukturer framför Historical actors are central to the history of knowledge as they are to all historical scholarship. Every country, every era has its biographies of eminent scientists, intellectuals, and educational reformers. Yet the theoretical currents that have left their mark on the historical and sociological study of knowledge since the 1960s have emphasized structures over actors, collectives over individ
A new series of 4-arylamino-3-nitrocoumarin analogues (4–18) have been synthesized and characterized by sophisticated spectroscopic techniques (1H NMR, 13C NMR) and mass spectrometry. All the new synthesized compounds were evaluated for their in vitro cytotoxic activity against the human cervix carcinoma cell line (KB-3-1) using resazurin assay with (+)-griseofulvin as the positive control (IC50 =
Pseudo-random functions are a fundamental building block in many cryptographic applications. In certain scenarios, a weaker notion (where security is restricted to uniformly random input), but more computationally efficient, called weak pseudo-random functions, is sufficient. In this work, we present new differential attacks on the main binary weak pseudo-random function constructions, namely the
Providing sensory feedback for myoelectric prosthetic users can not only increase the manipulation ability but can also introduce a feeling of embodiment. Previous research has demonstrated the feasibility of providing mechanotactile or vibrotactile feedback on the remaining stumps of amputees. To improve the recognition rate and reduce mental work load when identifying stimulation patterns, we pr
In this paper we present a novel method for predicting individual fingers movements from surface electromyography (EMG). The method is intended for real-time dexterous control of a multifunctional prosthetic hand device. The EMG data was recorded using 16 single-ended channels positioned on the forearm of healthy participants. Synchronously with the EMG recording, the subjects performed consecutiv
Reconstructing the evolution of baleen whales (Mysticeti) has been problematic because morphological and genetic analyses have produced different scenarios. This might be caused by genomic admixture that May have taken place among some rorquals. We present the genomes of six whales, including the blue whale (Balaenoptera musculus), to reconstruct a species tree of baleen whales and to identify phy
In recent decades, with the advancement of technologies facilitating reproduction, parents have been able to make decisions regarding their childrens’ reproductive potential: to preserve their fertility when threatened by genetic conditions or medical treatment; to use their gametes or embryos to make grandchildren; or even to collect their gametes posthumously and then use them to make grandchild
