description: The advent of the internet has allowed non-institutional actors to release information into the public realm due to reduced gatekeeping. Recently, this has raised concerns about the spread of low-credibility information such as misinformation and fake news. While most research has focused on low-credibility information spreading in the context of social media or mainstream media, less attention has been paid to whether they have been channeled into policy documents. Given the new waves of increasingly partisan think tanks, this study aims to identify the extent to which low-credibility information has also been spreading in policy documents. Using the Overton policy dataset, we identified the citations of low-credibility news sites and traced the citation patterns of those news sites onto congressional committee documents. We find that despite the alarming proportion of low credibility documents cited in policy documents, the channeling of misinformation from fake news articles onto legislation and policy-making is relatively rare, with the exception of “invited speaker” citations. Compared with the social media ecosystem that previous researchers have found to amplify the spread of fake news, the ecosystem of policy documents was found to suppress the spread of it by selecting out problematic misinformation claims at every step of the citation process. These findings provide reassurance that think tanks, while increasingly partisan, have generally not crossed the boundary towards producing misinformation. However, further work is needed to solidify these preliminary findings.

description: We report MERLIN, VLA, OCRA-p, VLBA, Effelsberg and GMRT observations beginning 4.5 days after the discovery of RS Ophiuchi undergoing its 2006 recurrent nova outburst. Observations over the first 9 weeks are included, enabling us to follow spectral development throughout the three phases of the remnant development. We see dramatic brightening on days 4 to 7 at 6 GHz and an accompanying increase in other bands, particularly 1.46 GHz, consistent with transition from the initial "free expansion" phase to the adiabatic expansion phase. This is complete by day 13 when the flux density at 5 GHz is apparently declining from an unexpectedly early maximum (compared with expectations from observations of the 1985 outburst). The flux density recovered to a second peak by approximately day 40, consistent with behaviour observed in 1985. At all times the spectral index is consistent with mixed non-thermal and thermal emission. The spectral indices are consistent with a non-thermal component at lower frequencies on all dates, and the spectral index changes show that the two components are clearly variable. The estimated extent of the emission at 22 GHz on day 59 is consistent with the extended east and west features seen at 1.7 GHz with the VLBA on day 63 being entirely non-thermal. We suggest a two-component model, consisting of a decelerating shell seen in mixed thermal and non-thermal emission plus faster bipolar ejecta generating the non-thermal emission, as seen in contemporaneous VLBA observations. Our estimated ejecta mass of 4+/-2x10^{-7} M_\odot is consistent with a WD mass of 1.4 M_\odot. It may be that this ejecta mass estimate is a lower limit, in which case a lower WD mass would be consistent with the data.

description: Safety is an important element of dependability. It is defined as the absence of accidents. Most accidents involving software-intensive systems have been system accidents, which are caused by unsafe inter-system or inter-component interactions. To validate the absence of system hazards concerning dysfunctional interactions, industrials call for approaches of modeling system safety requirements and interaction constraints among components. This paper proposes such a formalism, namely interface control systems (or shortly C-Systems). An interface C-System is composed of an interface automaton and a controlling automaton, which formalizes safe interactions and restricts system behavior at the meta level. This framework differs from the framework of traditional model checking. It explicitly separates the tasks of product engineers and safety engineers, and provides a top-down technique for modeling a system with safety constraints, and for automatically composing a safe system that conforms to safety requirements. The contributions of this work include formalizing safety requirements and a way of automatically ensuring system safety.

Fake star formation bursts: blue horizontal branch stars masquerade as young stars in optical integrated light spectroscopy

Publisher: name: arXiv
Year: 2009
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: Model color magnitude diagrams of low-metallicity globular clusters usually show a deficit of hot evolved stars with respect to observations. We investigate quantitatively the impact of such modelling inaccuracies on the significance of star formation history reconstructions obtained from optical integrated spectra. To do so, we analyse the sample of spectra of galactic globular clusters of Schiavon et al. with STECKMAP (Ocvirk et al.) and the stellar population models Vazdekis et al. and Bruzual & Charlot, and focus on the reconstructed stellar age distributions. Firstly, we show that background/foreground contamination correlates with E(B-V), which allows us to define a clean subsample of uncontaminated GCs, on the basis of a E(B-V) filtering. We then identify a "confusion zone" where fake young bursts of star formation pop up in the star formation history although the observed population is genuinely old. These artifacts appear for 70-100% of cases depending on the population model used, and contribute up to 12% of the light in the optical. Their correlation with the horizontal branch ratio indicates that the confusion is driven by HB morphology: red horizontal branch clusters are well fitted by old stellar population models while those with a blue HB require an additional hot component. The confusion zone extends over [Fe/H]=[-2,-1.2], although we lack the data to probe extreme high and low metallicity regimes. As a consequence, any young starburst superimposed on an old stellar population in this metallicity range could be regarded as a modeling artifact, if it weighs less than 12% of the optical light, and if no emission lines typical of an HII region are present.

description: S0 galaxies are often thought to be passively evolved from spirals after star formation is quenched. To explore what is occurring in S0s, we present a multi-wavelength study of NGC5866--an isolated nearby edge-on S0. This study shows strong evidence for dynamic activities in the interstellar medium, which are most likely driven by supernova explosions in the galactic disk and bulge. We utilize Chandra, HST, and Spitzer data as well as ground-based observations to characterize the content, structure, and physical state of the medium and its interplay with stars in NGC5866. A cold gas disk is detected with an exponential scale height of 100pc. Numerous off-disk dusty spurs are clearly present: prominent ones can extend as far as 300pc from the galactic plane and are probably produced by individual SNe, whereas faint filaments can have ~ kpc scale and are likely produced by SNe collectively in disk/bulge. We also detect substantial amounts of diffuse Ha- and Pa-emitting gas with a comparable scale height as the cold gas. We find that the heating of the dust and warm ionized gas cannot be explained by the radiation from evolved stars alone, strongly indicating the presence of young stars in the disk at a low formation rate of ~ 0.05Msun/yr. We reveal the presence of diffuse X-ray-emitting hot gas, which extends as far as 3.5kpc from the disk and can be heated easily by Type Ia SNe in the bulge. However, the temperature of this gas is ~ 0.2keV, substantially lower than what might be expected from the mass-loss of evolved stars and Type Ia SNe heating alone, indicating mass loading from cool gas is important. The total masses of the cold, warm and hot gases are ~ 5*10^8, 10^4 and 3*10^7Msun. The relative richness of the gases, undergoing circulations between disk/halo, is perhaps a result of its relative isolation.

description: We study the occurrence of ground-state factorization in dimerized $XY$ spin chains in a transverse field. Together with the usual ferromagnetic and antiferromagnetic regimes, a third case emerges, with no analogous in translationally-invariant systems, consisting of an antiferromagnetic Neél-type ground state where pairs of spins represent the unitary cell. Then, we calculate the exact solution of the model and show that the factorizing field represent an accidental degeneracy point of the Hamiltonian. Finally, we extend the study of the existence of ground-state factorization to a more general class of models.

description: Der vorliegende Beitrag beschäftigt sich mit dem zeitlichen Verlauf von Entscheidungsprozessen in Organisationen. Anhand eines Simulationsmodells werden die zeitlichen Konsequenzen von De-fiziten in der Problemzuwendung aufgezeigt. Gemeint ist mit dem Begriff der Problemzuwendung, die Zuwendung zu Kerntätigkeiten des Entscheidens: der Aufmerksamkeit, der Problemdefinition, der Erarbeitung von Problemlösungen und der Umsetzung der Lösungen. Problematisch ist das Thema der Problemzuwendung, weil Organisationen praktisch niemals mit nur einem einzigen Problem konfrontiert werden, sondern immer viele Probleme gleichzeitig auf Bearbeitung drän-gen. Der zeitliche Verlauf von Entscheidungsprozessen wird allerdings nicht allein von der Prob-lemzuwendung bestimmt, sondern auch von den vielen Hindernissen, die sich in jedem Entschei-dungsprozess ganz unvermeidlich (in mehr oder weniger großem Ausmaß) einstellen. Weitere wichtige Einflussgrößen sind der Problemzufluss, die Problemlösungskapazitäten und die Prob-lemlösungsfähigkeiten. Das Simulationsmodell, das im vorliegenden Beitrag vorgestellt wird, be-schreibt das Zusammenwirken dieser Größen. Es zeigt, dass der zeitliche Verlauf von Entschei-dungsprozessen ganz maßgeblich von strukturellen Parametern bestimmt wird, die sich nur in be-grenztem Maße beeinflussen lassen, die sich also – paradoxerweise – dem willentlichen Entschei-dungshandeln entziehen.
Power Shifts in International Standardization: Explaining a Leading Standard Setter in Telecommunication

description: Technical Standards have become a new arena of competition in the race for technological leadership since securing their control and ownership provides considerable economic and political advantages. Particularly telecommunication standards, which underpin global networks, can produce substantial economic and strategic benefits for the country and industry that largely shape their process and outcome. In light of these implications, new aspiring standard setters, such as China and South Korea, have actively increased their participation in international standards settings, challenging the predominant position of traditional standard setters such as the United States and European countries. The rise of new aspiring standard setters has provoked shifts in the power structures of international standardization regimes that had mostly reflected the preferences of traditional standard setters in the last decade, implying a redistribution of gains and costs among countries and industries. Despite this, only a few studies have focused on explaining power shifts in international standardization, drawing on IR/IPE theories. In addition, studies have only partially inquired about the political and economic of conditions that might explain such shifts. Against this background, this study aims to contribute to the literature focusing on power shifts in standardization by assessing under what conditions countries turn into leading standard setters. This is evaluated empirically by analyzing the capacity of six technological powers in shaping the three latest generations of telecommunication standards, namely 3G, 4G, and 5G. It deploys a multimethod approach to perform the analysis, combining a Qualitative Comparative Analysis (QCA) with a process tracing (PT) analysis. The study found that the combination of conditions composed of a great innovator, a large economic power, and a highly complementary domestic system resulted in the most consistent sufficiency path, suggesting that when countries hold roughly the same technological and economic capabilities, a complementary system conducive to a strong government-industry partnership proves crucial to shaping standardization. This interpretation calls for further research on the role and influence of governments in securing technological leadership by providing competitive advantages to industries contributing to global standards.
Photometric Orbits of Extrasolar Planets

Year: 2009
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: We define and analyze the photometric orbit (PhO) of an extrasolar planet observed in reflected light. In our definition, the PhO is a Keplerian entity with six parameters: semimajor axis, eccentricity, mean anomaly at some particular time, argument of periastron, inclination angle, and effective radius, which is the square root of the geometric albedo times the planetary radius. Preliminarily, we assume a Lambertian phase function. We study in detail the case of short-period giant planets (SPGPs) and observational parameters relevant to the Kepler mission: 20 ppm photometry with normal errors, 6.5 hour cadence, and three-year duration. We define a relevant "planetary population of interest" in terms of probability distributions of the PhO parameters. We perform Monte Carlo experiments to estimate the ability to detect planets and to recover PhO parameters from light curves. We calibrate the completeness of a periodogram search technique, and find structure caused by degeneracy. We recover full orbital solutions from synthetic Kepler data sets and estimate the median errors in recovered PhO parameters. We treat in depth a case of a Jupiter body-double. For the stated assumptions, we find that Kepler should obtain orbital solutions for many of the 100-760 SPGP that Jenkins & Doyle (2003) estimate Kepler will discover. Because most or all of these discoveries will be followed up by ground-based radial-velocity observations, the estimates of inclination angle from the PhO may enable the calculation of true companion masses: Kepler photometry may break the "m sin i" degeneracy.

description: We emphasize that a muon based neutrino factory could show the existence of light right-handed neutrinos, if a deficit in the number of detected events is observed at a near detector. This could be as large as ~10% if the size of the new interactions saturates the present limits from electroweak precision data, what is not excluded by the oscillation experiments performed up to now. A simple model realizing such a scenario can be obtained adding right-handed neutrinos to the minimal Standard Model, together with an extra scalar doublet and a triplet of hypercharge 1. In this case, however, the possible deficit is reduced by a factor of ~3, and the Yukawa couplings must be adequately chosen. This is also generically required if lepton flavour violation must be below present bounds.

description: Der Begriff „Beschäftigungsmanagement“ umspannt ein breites Themenspektrum.In einem sehr allgemeinen Verständnis geht es beim Beschäftigungsmanagement um die Konzipierung und Umsetzung der Personalbedarfsplanung, also darum, dass es weder zu einer Personalunterversorgung noch zu einer Personalüberdeckung kommt. Einen etwas anderen Akzent erhält das Beschäftigungsmanagement, wenn man ihm die Aufgabe zuweist, für eine Verstetigung der Beschäftigung zu sorgen, also Personalfluktuationen zu glätten und für eine kontinuierliche –die wirtschaftlichen Veränderungen flankierende– Beschäftigungsentwicklung zu sorgen. In wirtschaftlich unbeständigen Zeiten stellt sich diese Aufgabe als Herausforderung zur "Beschäftigungssicherung“. Das Beschäftigungsmanagement befasst sich aber nicht nur mit der rein "quantitativen“ Seite der Personalanpassung, sondern ebenso mit deren qualitativen Aspekten, also z.B. mit der Frage, welche Rolle die besonderen Charakteristika der Mitarbeiter (z.B. deren Qualifikation) bei Beschäftigungsentscheidungen spielen sollen.

Data was gathered from healthcare workers in both public and private hospitals in Somalia, focusing on key factors such as the extent of digital health technology adoption (e.g., Electronic Health Records (EHR), telemedicine platforms, mobile health apps) and their perceived usefulness and ease of use. Additionally, the adoption of digital health technology dataset includes self-reported measures of healthcare workers' performance, including patient care quality, efficiency, decision-making, and job satisfaction, as well as perceived workload, including hours worked, task complexity, and stress levels. The data also explores factors related to technology infrastructure (e.g., internet access, training), organizational support (e.g., leadership, training programs), and environmental factors (e.g., government policies, regulatory frameworks). Data was collected using a structured questionnaire administered to 286 healthcare workers across various public and private hospitals, including doctors, nurses, and administrative staff. The survey used Likert scale questions to assess the impact of digital health technologies on performance and workload.

description: We investigate an XMM-Newton observation of SCR 1845-6357, a nearby, ultracool M8.5/T5.5 dwarf binary. The binary is unresolved in the XMM detectors, however the X-ray emission is very likely from the M8.5 dwarf. We compare its flaring emission to those of similar very low mass stars and additionally present an XMM observation of the M8 dwarf VB 10. We detect quasi-quiescent X-ray emission from SCR 1845-6357 at soft X-ray energies in the 0.2-2.0 keV band, as well as a strong flare with a count rate increase of a factor of 30 and a duration of only 10 minutes. The quasi-quiescent X-ray luminosity of log L_x = 26.2 erg/s and the corresponding activity level of log L_x/L_bol = -3.8 point to a fairly active star. Coronal temperatures of up to 5 MK and frequent minor variability support this picture. During the flare, that is accompanied by a significant brightening in the near-UV, plasma temperatures of 25-30 MK are observed and an X-ray luminosity of L_x= 8 x 10^27 erg/s is reached. SCR 1845-6357 is a nearby, very low mass star that emits X-rays at detectable levels in quasi-quiescence, implying the existence of a corona. The high activity level, coronal temperatures and the observed large flare point to a rather active star, despite its estimated age of a few Gyr.

By eliminating all the auxiliary fields, we show that the simple action reduces to the one obtained by taking non-relativistic limit from the relativistic Chern-Simons-Matter theory proposed in the literature. As a further application, we give a manifestly supersymmetric derivation of the non-relativistic ABJM theory.

description: Begriff Mit dem Begriff eskalierendes Commitment beschreibt man ein Phänomen, wonach sich Menschen oft von einem einmal eingeschlagenen Kurs (d.h. einer konkreten Verhaltensweise, einer Verhaltensstrategie, einem Handlungsmuster) nicht abbringen lassen und zwar selbst dann nicht, wenn sich immer deutlicher abzeichnet, dass der eingeschlagene Kurs in die Irre führt. Unter Commitment versteht man die Festlegung auf ein bestimmtes Verhalten. Sich auf ein Verhalten festzulegen ist unumgänglich. Wenn es denn überhaupt möglich wäre, sich auf gar nichts festzulegen (also keinerlei Commitment aufzubringen), könnte man nicht ein einziges Ziel erreichen, ohne Commitment gibt es kein Handeln und damit auch kein Überleben. Commitment ist also ein „normales“ Phänomen. Problematisch wird Commitment allerdings dann, wenn man es nicht auch wieder aufgeben kann, wenn es also gewissermaßen eingefroren ist und sich gegen bessere Einsichten verschließt – oder sich vielleicht sogar verstärkt, also eskaliert, gerade dann, wenn es eigentlich geboten ist, sich von seinem Commitment wieder zu lösen.

description: A theory is presented which allows us to accurately calculate the surface tensions and the surface potentials of electrolyte solutions. Both the ionic hydration and the polarizability are taken into account. We find a good correlation between the Jones-Dole viscosity $B$-coefficient and the ionic hydration near the air-water interface. The kosmotropic anions such as fluoride, iodate, sulfate and carbonate, are found to be strongly hydrated and are repelled from the interface. The chaotropic anions such as perchlorate, iodide, chlorate and bromide are found to be significantly adsorbed to the interface. Chloride and bromate anions become weakly hydrated in the interfacial region. The sequence of surface tensions and surface potentials is found to follow the Hofmeister ordering. The theory, with only one adjustable parameter, quantitatively accounts for the surface tensions of 10 sodium salts for which there is experimental data.
Four novels of Patrick White
Creators: name: Bellette, Antony Frank
Publisher: name: University of British Columbia
Year: 2011

description: The intention of this thesis is to remedy the lack of serious critical attention given to the Australian novelist Patrick White. In Australia critical reaction has been tepid if not openly hostile, while in Britain and America only a small number of critics have dissociated White from his regional background and endeavoured to place him in a wider context. It is the purpose of the thesis to define this context, and to demonstrate that White is a highly original novelist in his own right. Of White's total output to the present time of six novels, only four are discussed here—The Aunt's Story (1948), The Tree of Man (1955), Voss (1957), and Riders in the Chariot (1961). As an introduction to these four novels the first chapter attempts to define White's place in the 'Australian tradition', to give an account of his local critical reception, and to discuss in brief the nature of his central preoccupations as an artist and the forms in which they are manifested. An examination of the four novels reveals the development of White's thought from the time when his artistic maturity became fully evident. From The Aunt's Story to Riders in the Chariot White is concerned above all with the besetting problems of the present time: the dilemma of the individual when faced with the break-down of traditional modes of thought, the possibility of meaningful communication, the problem of identity in a world of inner and outer chaos, and the origin and nature of evil in the world. From a subjective view of the world seen through the isolated consciousness of Theodora Goodman in The Aunt's Story, to the massive fourfold vision of Riders in the Chariot, White has demonstrated an ever-increasing range of tone and subject matter. He records with deadly accuracy the Australian 'comedy of manners', and in this respect he can be said to be the first genuine Australian satirist. At the other extreme, White is capable of rendering the profoundest mystical experience. Whether satirist or mystic, or mere observer and recorder of the world around him, White has at his disposal a lucid and poetic style which, though often startling in its unorthodoxy, is capable of conveying and enlarging upon the subtlest nuance of thought and image. In his style, and in his broadness of vision, lie White's chief claims to excellence. This study of the four novels, in chronological order, endeavours to demonstrate that underlying them is a constantly expanding vision, and that Patrick White is a significant and powerful novelist, and worthy of the closest critical attention.

The variation of the superconducting gap Δ as a function of the temperature was measured by recording the I-V characteristics. The experimental data are in good agreement with the dependence numerically computed from the BCS theory. The magnetic behavior of the maximum Josephson current was measured and both the magnetic penetration depth and the Josephson penetration depth were computed. By means of the Kulik theory on the junction self-induced resonances the microwave quality factor Q of the junctions, and surface impedance of the films have been estimated.

description: This paper examines good governance and administrative reform issues in 12 South Pacific Island countries. The paper concludes that to be effective, reform measures must specifically relate to the country’s geography, history, society and economy, and should not blindly follow other countries. Pacific Island countries vary is size: the smallest, Nauru, and the largest, Papua New Guinea, have total land areas of 21 and 453,000 square kilometres respectively. Pacific Islands are different from the other major island groups: the Caribbean and the Indian Ocean. Caribbean Islands are clustered together, and close to the United States market, Indian Ocean Islands are fast developing into the gateway to Africa for business in the East and South Asia. Pacific Islands do not have such advantages. They are scattered over a wider area, away from major markets and the size of their internal markets is small. The development of a new form of transport (containerisation) and advances in air transport technology have made the situation worse as the small volume of goods loaded and unloaded, and the small number of passengers did not justify the investment and reorganisation required to participate in these new forms of transport. Pacific Islands face severed destructive cyclones almost every year costing them a fortune in financial and resource terms. The ‘green-house’ effect is also threatening the physical existence of number of Pacific Island.

description: Die Ergebnisse, über die im Folgenden berichtet wird, wurden im Rahmen von zwei Meinungsumfragen ermittelt. Die erste Umfrage erfolgte im April 2009 und befasste sich mit der Wettbewerbssituation von Arbeitnehmern, die zweite Umfrage richtete sich auf die Beurteilung der betrieblichen Sozialordnung und wurde im November 2009 durchgeführt. Ergänzend zu den genannten Hauptfragen wurden in beiden Studien jeweils identische Fragen nach den beruflichen Folgen der Wirtschaftskrise gestellt. Eine der Fragen befasst sich speziell mit der Berücksichtigung von Arbeitnehmerinteressen in der Krise durch die Arbeitgeber, worauf in diesem Bericht etwas näher eingegangen wird. Zuvor werden jedoch die Ergebnisse der beiden Umfragen gegenübergestellt, die sich ganz allgemein mit der Arbeitssituation in der Wirtschaftskrise beschäftigen.

Year: 1993

description: We show that the hamiltonian formalism of compact QED on the lattice gauge transformations appear as representations of translations on a circle or on a line according to the boundary conditions on the wave functions. When gauge invariance is enforced, one gets at strong coupling a linear potential in the first case and a Coulombic potential in the second.

An analytic parameterization of self-gravity wakes in Saturn's rings, with application to occultations and propellers

description: We have developed a semi-analytic method of parameterizing N-body simulations of self-gravity wakes in Saturn's rings, describing their properties by means of only 6 numbers: 3 optical depths and 3 weighting factors. These numbers are obtained using a density-estimation procedure that finds the frequencies of various values of local density within a simulated ring patch. Application of our parameterization to a suite of N-body simulations implies that the distribution of local optical depths is trimodal, rather than bimodal as previous authors have assumed. Rings dominated by self-gravity wakes appear to be mostly empty space. The implications of this result for the analysis of occultation data are more conceptual than practical. The only adjustment needed is that the model parameter $τ_{gap}$ should be interpreted as representing the area-weighted average optical depth within the gaps (or inter-wake regions). The most significant consequence of our results applies to the question of why "propeller" structures observed in the mid-A ring are seen as relative-bright features, even though the most prominent features of simulated propellers are regions of relatively low density. We find preliminary quantitative support for the hypothesis that propellers would be bright if they involve a local and temporary disruption of self-gravity wakes, flooding the region with more "photometrically active" material (i.e., material that can contribute to the rings' local optical depth) even though the overall density is lower, and thus raising their apparent brightnesses in agreement with observations. We suggest that this mechanism be tested by future detailed numerical models.

Segment 1, between Pemberton and Wrightstown, traversed western portions of Fort Dix within the former Pemberton and Hightstown Railroad right-of-way. Auger testing and five posthole tests completed in Segment 1 document disturbed soils. No surface or subsurface artifacts were encountered and no potentially significant archaeological resources were identified.
Targeting Vascular Stiffness.
Creators: name: Mack, Christopher P
Publisher: name: Wolters Kluwer
Year: 2024

description: Artery stiffening, a biomechanical vascular property
closely related to but separate from hypertension, is
a strong and independent cardiovascular disease risk
factor that also predicts end-organ failure. Decreased
aortic compliance elevates the mechanical load on the
myocardium, increases peripheral pulse pressure which
damages high-flow organs such as the brain and kidneys,
and contributes to atherosclerotic plaque formation and
progression by altering mechanical stress signaling within
the vessel wall. Many cardiovascular risk factors in addition
to hypertension including aging, smoking, inflammation,
and obesity have been associated with vessel stiffening.
However, difficulties in assessing vascular stiffness as
an independent variable in experimental models have
made it challenging to determine the molecular mechanisms
that drive its progression. Although decreases in
aortic compliance were originally thought to be mediated
by changes in extracellular matrix content and composition
(ie, elastin degradation, collagen deposition), it has
now become clear that the intrinsic mechanical properties
of vascular smooth muscle cells (SMCs) also play a role.
