description: We explore a Z' boson with family-nonuniversal couplings to charged leptons. The general effect of Z-Z' mixing, of both kinetic and mass types, is included in the analysis. Adopting a model-independent approach, we perform a comprehensive study of constraints on the leptonic Z' couplings from currently available experimental data on a number of flavor-conserving and flavor-changing transitions. Detailed comparisons are made to extract the most stringent bounds on the leptonic couplings. Such information is fed into predictions of various processes that may be experimentally probed in the near future.

description: The article presents milk research and characteristics of indicators. Milk and dairy products (butter, cheese, fermented milk products and canned milk) are highly digestible and high in calories. They contain all the nutrients necessary for human life, growth and development of his body (proteins, fats, carbohydrates, min-eral salts, vitamins) and are among the most complete food products. So, milk and dairy products are of great importance for the organization of healthy and high-quality nutrition for the population. Milk is a biological fluid, the secretion of the mammalian mammary gland. It provides a young body with all the necessary nutrients, minerals and biologically active substances and is one of the main human food products and raw materials for the production of various dairy products [1].

description: In this paper, an analog linearizer using second harmonic signals feedforwarding is proposed. The harmonic generator of the proposed linearizer that consists of a small signal amplifier extracts second harmonic signals. A vector modulator, modulate fundamental signal with second harmonic signals, makes the inverse third order intermodulation distortion (IMD3) signals of power amplifier and controls amplitude/phase of them with modulation factors. As a result, this linearizer is suppressed IMD3 signals of power amplifier effectively. The test results show that IMD3 signals of power amplifier are suppressed more than 20dB for CW two-tone signals. Also, it’s improved the adjacent channel power ratio (ACPR) more than 7dB for CDMA (IS-95) signals.

description: Die Zunahme der Adipositas in der Bevölkerung ist ein weltweites Problem. Adipositas ist ein anerkannter Risikofaktor für die Entwicklung einer Osteoarthrose im Kniegelenk. Der Einfluss auf das postoperative Ergebnis nach primärer Knieendoprothesenversorgung ist in der Literatur jedoch kontrovers diskutiert. Das Ziel dieser prospektiven Studie war der Vergleich der mittelfristigen klinischen, funktionellen und radiologischen Ergebnisse von normalgewichtigen Patienten (BMI < 30 kg/m2) und adipösen Patienten (BMI ≥ 30 kg/m2) nach Versorgung mit einer Knieendoprothese vom Typ Medial Rotation Kniesystem (MRK). Es konnten 100 Knieendoprothesen bei 98 Patienten eingeschlossen werden, welche zwischen 2007 und 2011 ein MRK erhielten. Demographische Daten, Komplikationen, Revisionen sowie funktionelle Parameter (ROM, Flexion, Extension) wurden erfasst, klinische Scores (KSS, WOMAC) erhoben und Röntgenaufnahmen auf Lysesäume untersucht. Die Evaluation der Patienten erfolgte präoperativ, postoperativ und nach durchschnittlich 20 Monaten. Es konnte kein signifikant negativer Einfluss eines BMI ≥ 30 kg/m2 auf das klinische und funktionelle Ergebnis nachgewiesen werden, jedoch war eine negative Tendenz in der Funktionalität bei adipösen Patienten erkennbar. Ein Zusammenhang zwischen einer Adipositas und einer erhöhten Wahrscheinlichkeit für das Auftreten von Lysesäumen konnte nicht hergestellt werden. Bei adipösen Patienten kam es postoperativ signifikant häufiger zu Wundheilungsstörungen. Zudem waren die Patienten mit einem BMI ≥ 30 kg/m2 zum Zeitpunkt der Operation durchschnittlich 2,5 Jahre jünger als Normalgewichtige.

description: Indigenous early language learning programs for young children, commonly known as “language nests”, are well established in New Zealand and Hawai‘i. By contrast, in Canada there are few such programs and the concept is not commonly known in Indigenous communities. This study presents the experiences and insights of twenty-one fluent Elders, administrators, language teachers, early childhood educators and parents who have been involved in language nest programs in the start up years. These interviews were shaped by research questions on key issues, challenges and promising approaches. A thematic analysis was used to highlight dominant themes and to honour the words and ideas of the participants. The participants in this study described the benefits that young children and fluent Elders experience through their involvement in early language immersion programs. Research participants shared visions for nests, deeply held beliefs about the need to fully immerse young children in their language, as well as promising approaches. These insights give evidence that Language Nests support young children to understand, speak and sing in the language, and that participation in these programs has the added effect of enhancing the daily lives of involved fluent Elders. This research is presented in service to the reclamation of early learning, Indigenous languages, and intergenerational ways of knowing and being.

description: The current state of the soil cover is determined primarily by the activities of human society. This factor is today in the first place among the factors transforming the soil cover of the planet. Intensification of agricul-ture, increase of technogenic load on land resources, uncontrolled use of chemicals in conditions of low tech-nological culture and other influences lead to deterioration of soil quality, reduction of their fertility. Contam-ination of the atmosphere, water and soil with heavy metals is a very serious problem, because most cultural landscapes are affected by them, which in turn affects both crop productivity and product quality. Analysis of heavy metal contamination of meadows and pastures showed that the maximum permissible concentrations of lead, cadmium, zinc and copper were not detected. Thus, the concentration of lead, cadmium, zinc and copper in the soil of meadows was lower than the maximum allowable concentrations of 120; 7.7; 2.5; and 18.7 times. Less lead, cadmium, zinc and copper were found in pasture soils, respectively, in 113; 1.08; 1.09 and 1.88 times compared with the maximum allowable concentrations. Our studies have shown that the content of lead and copper in arable land is 1.03 and 1.20 times higher, respectively, compared to the maximum allowable concentrations. And the concentration of cadmium and cop-per is lower by 11.66 and 2.16 times, respectively, compared to the maximum allowable concentrations. In the soils of perennial grasses, a lower concentration of lead, cadmium, zinc and copper, respectively, was found in 1.25; 1.84; 4.25 and 1.05 times compared to the maximum allowable concentrations.

description: Recently, authors have proposed neural networks for modelling the temperature dependences of elements and parameters of microwave transistor small-signal equivalent circuit including noise. This neural model enables the prediction of modelled device noise parameters for any operating temperature. In this paper, an improvement of the neural model accuracy is proposed. It is done by using an additional neural network aimed to correct the noise parameters’ values.
A homomorphism between link and XXZ modules over the periodic Temperley-Lieb algebra

description: We study finite loop models on a lattice wrapped around a cylinder. A section of the cylinder has N sites. We use a family of link modules over the periodic Temperley-Lieb algebra EPTL_N(β, α) introduced by Martin and Saleur, and Graham and Lehrer. These are labeled by the numbers of sites N and of defects d, and extend the standard modules of the original Temperley-Lieb algebra. Beside the defining parameters β=u^2+u^{-2} with u=e^{iλ/2} (weight of contractible loops) and α(weight of non-contractible loops), this family also depends on a twist parameter v that keeps track of how the defects wind around the cylinder. The transfer matrix T_N(λ, ν) depends on the anisotropy νand the spectral parameter λthat fixes the model. (The thermodynamic limit of T_N is believed to describe a conformal field theory of central charge c=1-6λ^2/(π(λ-π)).) The family of periodic XXZ Hamiltonians is extended to depend on this new parameter v and the relationship between this family and the loop models is established. The Gram determinant for the natural bilinear form on these link modules is shown to factorize in terms of an intertwiner i_N^d between these link representations and the eigenspaces of S^z of the XXZ models. This map is shown to be an isomorphism for generic values of u and v and the critical curves in the plane of these parameters for which i_N^d fails to be an isomorphism are given.

description: We propose a new solution for sensing a terahertz (THz) wavefront based on a THz reference-less shear interferometer. The key component of the experimental configuration of the proposed interferometer is a THz Ronchi phase grating (RPG). The RPG is custom designed and fabricated for a 0.28 THz source using mechanical milling on a block of high-density polyethylene with a computer numerical control machine. It acts as a shearing element that generates two diffraction orders, thereby, creating two laterally shifted copies of the investigated wavefront in the sensor plane where a THz camera is placed. The direction of the shear can be varied by rotating the grating. Since the grating is a phase grating, the diffraction efficiency is very high. The approach is verified experimentally by demonstrating interferograms of a spherical wave and wavefront reconstruction from five different shears using a gradient-based iterative process.

description: Jeder medizinische Eingriff bedarf einer ärztlichen Aufklärung und einer informierten Einwilligung des Patienten. Doch die Unterschrift des Patienten auf dem Aufklärungsbogen ist nicht gleichzusetzen mit seinem Verständnis des Eingriffs. Aufgrund dieser Tatsache wurden in die vorliegende prospektive Studie zwischen Januar 2015 und November 2016 N=215 Patienten, die sich elektiv einer digitalen Subtraktions-Angiographie, perkutanen transluminalen Angioplastie oder einem offenen oder endovaskulären Eingriff an der Aorta unterzogen, eingeschlossen. Zudem wurden die Patienten konsekutiv in drei verschiedene Gruppen aufgeteilt: Standardaufklärung, Vortragsgruppe, Gehtrainingsgruppe). Das Ziel war, das Verständnis der Patienten bezüglich des Aufklärungsgesprächs mittels Fragebögen zu erfassen und beeinflussende Faktoren zu ermitteln. Die Analyse der Daten ergab, dass die zuvor im Aufklärungsgespräch genannte Diagnose in 35,9 %, der Eingriff in 44,2 %, die Inzisionsstelle in 74,4 %, mindestens eine leichte Komplikation in 38,5 % und mindestens eine schwere Komplikation in 22,4 % erinnert wurde. Zwischen den verschiedenen Trainings- und OP- Gruppen gab es keine signifikanten Unterschiede in der Erinnerungsrate. Das Alter der Patienten war der einzige Faktor, der signifikant mit der fehlenden Erinnerung irgendeiner möglichen, im Aufklärungsgespräch genannten, Komplikation assoziiert war (p=0,016, multiple logistische Regression).

description: We introduce a nonparametric graphical model whose observations on vertices are functions. Many modern applications, such as electroencephalogram and functional magnetic resonance imaging (fMRI), produce data are of this type. The model is based on additive conditional independence (ACI), a statistical relation that captures the spirit of conditional independence without resorting to multi-dimensional kernels. The random functions are assumed to reside in a Hilbert space. No distributional assumption is imposed on the random functions: instead, their statistical relations are characterized nonparametrically by a second Hilbert space, which is a reproducing kernel Hilbert space whose kernel is determined by the inner product of the first Hilbert space. A precision operator is then constructed based on the second space, which characterizes ACI, and hence also the graph. The resulting estimator is relatively easy to compute, requiring no iterative optimization or inversion of large matrices. We establish the consistency and the convergence rate of the estimator. Through simulation studies we demonstrate that the estimator performs better than the functional Gaussian graphical model when the relations among vertices are nonlinear or heteroscedastic. The method is applied to an fMRI dataset to construct brain networks for patients with attention-deficit/hyperactivity disorder. Supplementary materials for this article are available online

description: In den Neurowissenschaften geht man aktuell davon aus, dass Gehirnfunktionen nicht allein einzelnen Gehirnregionen, sondern neuronalen Netzwerken zugeordnet werden können. Eine Methode der Bildgebung um derartige Netzwerke darzustellen, ist die Konnektivitätsanalyse von funktionellen Magnetresonanztomographie-Aufnahmen im Ruhezustand. Frühere Studien zeigten in diesem Zusammenhang eine stärkere Entkoppelung der Aktivität von zwei Gehirnnetzwerken, dem Salienz- und dem Default-Mode-Netzwerk bei Patienten mit pathologisch kompromittierter Aufmerksamkeit im Rahmen eines Aufmerksamkeits-Defizits-Hyperaktivitäts-Syndroms. In der hier beschriebenen Studie wurde analysiert, inwiefern die Interaktion zwischen dem Salienz- und Default-Mode-Netzwerk, mit der Interferenz-Suszeptibilität gegenüber salienten Stimuli, einem Maß für Ablenkbarkeit, bei gesunden männlichen Probanden korreliert. Zur Bestimmung der Interferenz-Suszeptibilität führten die Probanden einen Test durch, in welchem ihnen Stimuli unterschiedlicher Salienz als Distraktoren gezeigt wurden, während sie die Aufgabe erhielten in möglichst kurzer Zeit einen auditorischen Stimulus zu klassifizieren. Es zeigte sich eine signifikant verminderte funktionelle Dissoziation zwischen jeweils einer Region des Salienz- und des Default-Mode-Netzwerks bei Probanden mit erhöhter Interferenz- Suszeptibilität gegenüber hochsalienten Stimuli. Dieses Ergebnis untermauert die Bedeutung der Interaktion dieser beiden Netzwerke für die Aufmerksamkeits-Funktion. So könnte zum Beispiel versucht werden, die Interaktion dieser beiden neuronalen Netzwerke im Rahmen eines Neurofeedback-Trainings zu modulieren und neue Therapieansätze für psychiatrische Erkrankungen, welche mit einem Aufmerksamkeits-Defizit einhergehen, zu entwickeln.

Seismic vulnerability assessment and retrofit optimization of non-code conforming buildings with consideration of mainshock-aftershock earthquake
Creators: name: Duerr, Konrad
Publisher: name: University of British Columbia
Year: 2014

description: Many seismically active locations in Canada and around the world have structures built before modern seismic design practices were established. More recently, the effects of aftershocks have been included as an important consideration when assessing the seismic risk of non-code conforming structures. Often, the large stock of at-risk structures limits the available resources to mitigate seismic damage. In this work, modern simulation software was used to perform a seismic hazard analysis of a non-code conforming reinforced-concrete structure including the effects of mainshock-aftershock sequences. Structure performance was measured with both drift and damage accumulation methods. Additionally, optimization methods were integrated with the structural analysis to reduce the cost and improve the performance of seismic mitigation retrofit schemes. Modern parallel computing techniques were implemented to reduce the overall computation time, further improving the usability of the process. The resulting retrofit location schemes were presented and compared.

description: Previous work has demonstrated that categories are useful and expressive models for databases. In the present paper we build on that model, showing that certain queries and constraints correspond to lifting problems, as found in modern approaches to algebraic topology. In our formulation, each so-called SPARQL graph pattern query corresponds to a category-theoretic lifting problem, whereby the set of solutions to the query is precisely the set of lifts. We interpret constraints within the same formalism and then investigate some basic properties of queries and constraints. In particular, to any database $π$ we can associate a certain derived database $\Qry(π)$ of queries on $π$. As an application, we explain how giving users access to certain parts of $\Qry(π)$, rather than direct access to $π$, improves ones ability to manage the impact of schema evolution.

description: We present a new technique for fast form measurement based on imaging with partially coherent illumination. It consists of a 4 f-imaging system with a digital micro-mirror device (DMD) located in the Fourier plane of its two lenses. The setup benefits from spatially partially coherent illumination that allows for depth discrimination and a DMD that enables a fast depth scan. Evaluating the intensity contrast, the 3D form of an object is reconstructed. We show that the technique additionally offers extended depth of focus imaging in microscopy and short measurement times of less than a second.

description: A mathematical optimization approach , including scaling properties of FET devices, has been used in order to control strong nonlinear non autonomous MMIC functions. In particular broadband distributed power amplification and balanced multiplication has been studied. Optimum choice of gate length and embedding impedances permits us to obtain the best compromise between the main performance parameters such as broadband gain, return loss etc, and the power behaviour. Good agreement between theoretical and experimental results has been obtained in order to validate the mathematical approach.

description: Consider an $n \times n$ non-Hermitian random matrix $M_n$ whose entries are independent real random variables. Under suitable conditions on the entries, we study the fluctuations of the entries of $f(M_n)$ as $n$ tends to infinity, where $f$ is analytic on an appropriate domain. This extends the results for symmetric random matrices to the non-Hermitian case.

description: How important are friendships in determining success by individuals and teams in complex collaborative environments? By combining a novel data set containing the dynamics of millions of ad hoc teams from the popular multiplayer online first person shooter Halo: Reach with survey data on player demographics, play style, psychometrics and friendships derived from an anonymous online survey, we investigate the impact of friendship on collaborative and competitive performance. In addition to finding significant differences in player behavior across these variables, we find that friendships exert a strong influence, leading to both improved individual and team performance--even after controlling for the overall expertise of the team--and increased pro-social behaviors. Players also structure their in-game activities around social opportunities, and as a result hidden friendship ties can be accurately inferred directly from behavioral time series. Virtual environments that enable such friendship effects will thus likely see improved collaboration and competition.

Es wurde zunächst anhand zweier verschiedener Verhaltensmodelle eine erhöhte Aktivität der homozygot PRG1-defizienten Tiere im Acht-Arm-Radiallabyrinth und eine schlechtere Lernleistung aller PRG1-defizienten Mäuse gezeigt. Zudem konnte die Motility-Box ein motorisch-stereotypisches Verhalten darlegen. Immunhistochemisch konnte eine signifikant erhöhte Konzentration an NPY im Hippocampus der homozygot PRG1-defizienten Tiere gezeigt werden. Die PARV-immunpositiven Neurone im Septum und Hippocampus waren ebenso wie die ChAT-immunpositiven Neurone im Septum nicht signifikant verändert im Vergleich der Geschwister. Die TIMM-Färbung ergab allerdings einen signifikant erhöhten Anteil an Moosfasern im Gyrus dentatus sowie an infra/intrapyramidalen Fasern der homozygot PRG1-defizienten Tiere. Molekularbiologisch zeigten die Wachstumsfaktoren im Hippocampus mittels ELISA einen Trend zur erhöhten BDNF-Konzentration der homozygot PRG1-defizienten Tiere. NT3 war bei beiden Gruppen der PRG1-defizienten Tieren im Vergleich zu den Wildtyp-Geschwistern erhöht, wobei die homozygot PRG1-defizienten Tiere absolut die höheren Werte zeigten. NGF erbrachte ebenso wie das Hormon CRF keinen Unterschied innerhalb der drei Gruppen. Die Arbeit bestätigt damit den Einfluss von PRG1 auf das Verhalten der PRG1-defizienten Tiere und liefert wichtige Hinweise für morphologische und molekularbiologische Veränderungen im Hippocampus dieser Tiere.

description: In this work it is proven that on the load reflection coefficient plane of a microwave low noise GaAs MESFET amplifier a locus of optimum values {TLO } does exist depending only on the transistor noise and scattering parameters and on the operating power gain to be obtained. The existence of this locus is proven in a rigorous way for lossless input equalizer amplifiers. The knowledge of {TLO } allows us to foresee the noise figure, the amplifier input reflection coefficient and any other performance useful in the low noise amplifier design.

description: Diabetic nephropathy is the leading cause of chronic kidney disease as well as the primary complication of diabetes worldwide. Although, the molecular function of endoplasmic reticulum (ER) stress in diabetes mellitus (DM) is well-established in the liver and the pancreas, the role of ER stress in diabetic nephropathy remained unknown when starting this project. We uncovered important pathophysiological consequences of insulin resistance and hyperglycemia towards maladaptive ER stress and its contributions to the progression of diabetic nephropathy (dNP). This study establishes causality between defective insulin signaling leading to maladaptive ER stress in podocytes and impaired kidney function in DM. Searching for potential pathways compensating for impaired insulin signaling, we identified a new role of the coagulation system. Coagulation protease signaling rescues defective insulin signaling in podocytes, thus, protecting these cells from the detrimental effects of hyperglycemia. Specifically, the coagulation protease activated protein C (aPC), known for its pleiotropic cytoprotective effects, activates the inositol-requiring enzyme 1α (IRE-1α) - spliced X-box-binding protein 1 (sXBP1) signaling arm of the adaptive unfolded protein response (UPR), restoring ER homeostasis. Insulin- and aPC-dependent signaling, despite acting through disjunct receptors, both signal through p85α/β- phosphatidylinositol 3-kinase (PI3K) to induce nuclear localization of sXBP1. Development of therapeutics that mimic aPC-signaling and restore ER homeostasis, or alterantive approaches to restore ER homeostasis in insulin resistant tissues constitute a new therapeutic approach in dNP.

description: In high data rate optical-fiber, it is necessary to employ an ultra broad-band transimpedance amplifier. In this paper, we present a technique for the design of a transimpedance amplifiers. It can be applied as well to the design of interstage equalizers for microwave transimpedance amplifiers. In the version described in this paper, the optimisation process is applied to the transimpedance gain and noise which is adjusted. Based on the load charge matching technique, a sequential procedure to design multistage microwave transimpedance amplifiers is developed. The synthesis of network is carried out with lumped elements. Then we give an example of design of a two stage 3-7 GHz transimpedance amplifier with HEMT transistor.
Calculating Jet $v_n$ and the Event Plane in the Presence of a Jet

description: Advances in measurements of jets and collective phenomena in ultrarelativistic heavy ion collisions have led to further understanding of the properties of the medium created in such collisions. Measurements of the correlations between the axes of reconstructed jets and the reaction plane or second-order participant plane of the bulk medium (defined as jet $v_2$), as well as the higher-order participant planes (jet $v_n$), provide information on medium-induced parton energy loss. Additionally, knowledge of jet $v_n$ as well as the ability to reconstruct the event plane in the presence of a jet are necessary in analyses of jet-triggered particle correlations, which are used to study medium-induced jet shape modification. However, the presence of a jet can bias the event plane calculation, leading to an overestimation of jet $v_2$. This paper proposes a method for calculating jet $v_2$ (and by extension, the higher jet $v_n$ harmonics) and the event plane in an unbiased way, using knowledge of the azimuthal angle of the jet axis from full jet reconstruction.

description: An abrupt change in microstrip linewidth, commonly called a microstrip impedance step, is a discontinuity that appears frequently in MMICs, such as, stepped impedance transformers and matching networks for example. Therefore, the accurate description of these step-discontinuties is important for the computer-aided design of conventional and monolithic MICs. In this work we have studied the set of modes that appears in a boxed microstrip in order to apply modal analysis in the spectral domain to the study of simple and cascaded step discontinuities. In order to check its precision, our method has been applied to a nine section low-pass filter, made up of a cascade of microstrip step discontinuities. Several filters have been designed, built and tested at different frequencies. We have compared these designs with Touchstone and shown that at low frequencies both methods give similar results, but when the frequency is higher, the Touchstone results are farther from the experimental results than the design obtained with the modal analysis method.

description: According to Shibukawa, ternary systems defined on quasigroups and satisfying certain conditions provide a way of constructing dynamical Yang-Baxter maps. After noticing that these conditions can be interpreted as 3-dimensional compatibility of equations on quad-graphs, we investigate when the associated dynamical Yang-Baxter maps are in fact parametric Yang-Baxter maps. In some cases these maps can be obtained as reductions of higher dimensional maps through compatible constraints. Conversely, parametric YB maps on quasigroups with an invariance condition give rise to 3-dimensional compatible systems. The application of this method on spaces with certain quasigroup structures provides new examples of multi-parametric YB maps and 3-dimensional compatible systems.

description: We give a complete classification of reductive symmetric pairs (g, h) with the following property: there exists at least one infinite-dimensional irreducible (g,K)-module X that is discretely decomposable as an (h,H \cap K)-module. We investigate further if such X can be taken to be a minimal representation, a Zuckerman derived functor module A_q(λ), or some other unitarizable (g,K)-module. The tensor product $π_1 \otimes π_2$ of two infinite-dimensional irreducible (g,K)-modules arises as a very special case of our setting. In this case, we prove that $π_1 \otimes π_2$ is discretely decomposable if and only if they are simultaneously highest weight modules.

description: Cytoprotection by activated protein C (aPC) following ischemia-reperfusion injury (IRI) is associated with apoptosis inhibition. However, IRI is hallmarked by inflammation and hence conceptually cell-death forms disjunct from immunologically silent apoptosis are more likely to be relevant. As pyroptosis, cell death resulting from inflammasome activation, is typically observed in IRI we speculated that aPC ameliorates IRI by inhibiting inflammasome activation. Here we analyzed the impact of aPC on inflammasome activity in myocardial and renal IRI. aPC treatment reduced infarct size and Nlrp3 inflammasome activation in mice. Kinetic in vivo analyses revealed that inflammasome activation preceded myocardial injury and apoptosis. The constitutively active Nlrp3A350V mutant abolished aPC’s protective effect, demonstrating that Nlrp3 suppression is required for aPC-mediated protection from IRI. In vitro aPC inhibited inflammasome activation via PAR-1 and mTORC1 signaling. Inhibiting PAR-1 signaling abolished aPC’s ability to restrict inflammasome activity and myocardial infarction, while specifically inhibiting aPC’s anticoagulant properties did not impair aPC’s effect on inflammasome activation. Targeting biased PAR-1 signaling via parmodulin-2 restricted inflammasome activation and limited myocardial IRI. aPC’s renal tissue protective effect was likewise dependent on Nlrp3 inflammasome suppression. These studies reveal that aPC protects from IRI by restricting mTORC1 dependent inflammasome activation and that mimicking biased aPC-PAR1 signaling using parmodulins may be a feasible therapeutic approach to combat IRI.
