This paper presents a straightforward method to convert non-uniformly sampled data to uniform samples in order to be processed by some off-line techniques such as system identification. In such scenarios, we deal with a finite-length measurement sequence. We assume periodic extension of the signals, which results in a simple system of linear equations. Furthermore, we take into account a number of
The thermodynamic behavior of a three-dimensional off-lattice model for protein folding is probed. The model has only two types of residues, hydrophobia and hydrophilic. In absence of local interactions, native structure formation does not occur for the temperatures considered. By including sequence independent local interactions, which qualitatively reproduce local properties of functional protei
A number of behaviours influence health in a non-monotonic way. Physical activity and alcohol consumption, for instance, may be beneficial to one's health in moderate but detrimental in large quantities. We develop a demand-for-health framework that incorporates the feature of a physiologically optimal level. An individual may still choose a physiologically non-optimal level, because of the trade-
Direct conversion receivers are widely used for full duplex mobile radio communication systems. This paper describes a novel SAW-less single-ended RF amplifier connected to a single-ended mixer with a feedback loop that suppresses the second-order distortion from TX cross modulation of the LO-leakage as well as DC-offset at the mixer output. In Monte Carlo simulations the design achieves +47 dBm m
Hyperinsulinemia is an adaptive mechanism that enables the maintenance of normoglycemia in the presence of insulin resistance. We assessed whether glucagon is also involved in the adaptation to insulin resistance. A total of 1,437 individuals underwent an oral glucose tolerance test with measurements of circulating glucose, insulin, and glucagon concentrations at 0, 30 and 120 min. Early glucagon
To meet yet higher speed and capacity demands, 5G will turn to mm-waves for more bandwidth. In this paper some receiver design issues occurring when moving from current 4G bands to mm-wave frequencies are discussed. The local oscillator phase noise increases by 6dB/octave with frequency and will ultimately limit spectrum efficiency. To analyze this, a phase noise model, based on a test chip design
Vasodilator responses to anandamide (arachidonylethanolamide) and potassium ions were compared with those mediated by endothelium-derived hyperpolarizing factor (EDHF) in guinea-pig isolated basilar artery contracted with prostaglandin F(2α). In this artery, EDHF-mediated responses can be evoked by acetylcholine in the presence of both indomethacin (10 μM) and N(G)-nitro-L-arginine (0.3 mM). In en
1. In the presence of N(G)-nitro-L-arginine (L-NOARG, 0.3 mM) and indomethacin (10 μM), the relaxations induced by acetylcholine and the calcium (Ca) ionophore A23187 are considered to be mediated by endothelium-derived hyperpolarizing factor (EDHF) in the guinea-pig basilar artery. 2. Inhibitors of adenosine 5'-triphosphate (ATP)-sensitive potassium (K)-channels (K(ATP); glibenclamide, 10 μM), vo
Popular Abstract in Swedish Avhandlingen har flera uppgifter, som på olika sätt hör ihop. Den första uppgiften går ut på att undersöka samvetskonflikter i det svenska samhället. I denna typ av konflikt är samvete och samvetsfrihet centrala begrepp och de är viktiga för att förstå och ta ställning i konflikterna. Den andra uppgiften blir därför att undersöka och förstå begreppet samvete och ge ett The aim of this study is to describe and analyse four conflicts and two concepts. Four conflicts of conscience found in Swedish society are studied in the second chapter. 2.2 - the state’s requirement that all male citizens do military service and the citizen’s right to refuse to do military service. 2.3 - obligatory course requirements and the college student’s right to refuse participation in c
Due to demanding customer needs and evolving technology, software organizations are forced to trade individual functional and non-functional product quality profiles against other factors such as cost, time, or productivity. The ability to influence or even control these factors requires a deep understanding of the complex relations between process and product attributes in relevant contexts. Base
Having access to realistic and empirically grounded passenger valuations of public transport trip components facilitate the undertaking of necessary trade-offs during planning of transport networks. Discrete choice estimation of path choice preferences is a practical way to obtain such preferences. This paper proposes a new take on the empirical foundation of path choice estimation based on reveal
Background. School health programs need to target all aspects of physical, psychological, and social well-being. Using a slightly modified version of the COSMIN Risk of Bias checklist, we developed and conducted the first validation of the School Health Assessment Tool for Primary Schools (SHAT-PS). Method. The exploratory sequential mixed method was used in this study. In the first phase, scienti
Bone tissue has a strong intrinsic regenerative capacity, thanks to a delicate and complex interplay of cellular and molecular processes, which tightly involve the immune system. Pathological settings of anatomical, biomechanical or inflammatory nature may lead to impaired bone healing. Innovative strategies to enhance bone repair, including the delivery of osteoprogenitor cells or of potent cytok
BACKGROUND: Primary headache disorders such as migraine and cluster headache exhibit circadian and circannual variations in attack onset. Melatonin plays a central role in regulating biological rhythms and likely influences the timing of headache attacks. Recent evidence suggests melatonin may be a promising treatment for migraine and cluster headache; however, underlying mechanisms need to be elu
BACKGROUND: Traumatic brain injury (TBI) constitutes a global epidemic. Overall outcome is poor, with mortality ranging from 10 to 70% and significant long-term morbidity. Several experimental reports have claimed effect on traumatic edema, but no clinical trials have shown effect on edema or outcome. Antisecretory factor, an endogenous protein, is commercially available as Salovum®, which is clas
When Iran directed over 300 missiles and drones at Israel on April 13, Jordan helped fend off the attack. Initial media reports suggested that several other Arab states assisted in Israel’s defense, efforts they later denied. Nonetheless, a chorus of Israeli leaders, as well as some observers in Washington, interpreted these acts as a sign of a major shift. These Arab states, the argument went, wo
