The frequency of laying gaps was studied in a nestbox breeding population of Blue Tits Parus caeruleus during the breeding season of 1990. In as many as 27% of the 55 clutches studied, laying was interrupted for at least one day. It is concluded that the interruption of egg laying depends on food availability since the frequency of laying gaps decreased in clutches laid by females experimentally p
In this work, we propose a novel measure of distance for quantifying dissimilarities between signals observed on a graph. Building on a recently introduced optimal mass transport framework, the distance measure is formed using the second-order statistics of the graph signals, allowing for comparison of graph processes without direct access to the signals themselves, while explicitly taking the dyn
There is a scarcity of work examining the relationship between culture and pain-related caregiver behaviors. Moreover, no pediatric pain studies have examined the relationship between caregiver cultural values and pain-related caregiver behaviors nor discern if this process is mediated by caregiver parenting styles and moderated by ecosocial context. Based on cross-cultural developmental theories,
In this work, we propose to utilize a recently developed covariance matrix interpolation technique in order to improve noise reduction in multi-microphone setups in the presence of a moving, localized noise source. Based on the concept of optimal mass transport, the proposed method induces matrix interpolants implying smooth spatial displacement of the noise source, allowing for physically reasona

The human B1 bradykinin (BK) receptor (B1R) is more efficacious than the human B2 BK receptor (B2R) in both ligand-independent and agonist-dependent coupling to Gq/11-mediated phospholipase Cβ activity. In fact, B1R is constitutively active, whereas B2R exhibits little if any constitutive activity. To evaluate the role of the C-terminal domain in receptor Gq/11 coupling, we constructed chimeric an
In this report, we show that desensitization regulates ligand- independent, spontaneous activity of the human B2 bradykinin (BK) receptor, and the level of spontaneous receptor activity determines the action of the BK antagonists and partial receptor agonists NPC17731 and HOE140 as agonists or inverse agonists. Spontaneous receptor activity was monitored by measuring basal cellular phosphoinositid
Elevated formation of bradykinin (BK) and Lys-BK or kallidin (KD) and their carboxypeptidase metabolites desArg9BK and desArg10KD is evident at sites of inflammation. Moreover, B2 receptors (B2R) which mediate the action of BK and KD, participates in the acute stage of the inflammatory and pain response, whereas B1 receptors (B1R), through which desArg9BK and desArg10KD act, partake in the chronic
In order to identify agonist- and antagonist-binding epitopes in the human B1 and B2 bradykinin (BK) receptors, we exploited the ability of these receptors to discriminate between peptide ligands that differ only by the absence (B1) grid presence (B2) of a C-terminal Arg. This was done by constructing chimeric proteins in which specific domains were exchanged between these receptors as recently de
The B1 and B2 bradykinin (BK) receptor subtypes belong to the GPCR faro ily, and they discriminate between peptides that differ only by the absence and presence of a C-terminal Arg, To identify receptor residues conferring tigand spe.cificity, chimeric constructs in which TM-III were exchanged between the receptors were expressed and assayed by radioligand binding and fluorescence Ca2+ imaging in
After a reperfused myocardial infarction (MI), dynamic tissue changes occur (edema, inflammation, microvascular obstruction, hemorrhage, cardiomyocyte necrosis, and ultimately replacement by fibrosis). The extension and magnitude of these changes contribute to long-term prognosis after MI. Cardiac magnetic resonance (CMR) is the gold-standard technique for noninvasive myocardial tissue characteriz
We present a terahertz quantum cascade laser operating on a thermoelectric cooler up to a record-high temperature of 210.5 K. The active region design is based on only two quantum wells and achieves high temperature operation thanks to a systematic optimization by means of a nonequilibrium Green's function model. Laser spectra were measured with a room temperature detector, making the whole setup
We present a new way of performing hypothesis tests on scattering data, by means of a perturbatively calculable classifier. This classifier exploits the “history tree” of how the measured data point might have evolved out of any simpler (reconstructed) points along classical paths, while explicitly keeping quantum–mechanical interference effects by copiously employing complete leading-order matrix
