Anthurium clavigerum

description: Anthurium clavigerum Poepp. & Endl. Material examined. Parque Nacional Darién, Cerro Pirre, Rancho Frío; 08°01′16″N, 077°44′04″W; 103 m; 13 Apr. 2016; O. O. Ortiz 2548 (PMA). Identification. This species is notable by having large pedatisect leaves, with sinuate margins and for its huge pendant inflorescence. This Anthurium has the largest leaves in comparison with the rest of the Central American species (Croat 1983). They can be confused with sympatric A. pentaphyllum var. bombacifolium (Schott) Madison and A. kunthii Poepp., but both differ by having slender stems, smaller leaves with entire or subauriculate lobes (never markedly sinuate). Distribution and ecology. Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Guyana, French Guiana, Honduras, Nicaragua, Panama, Peru, and Venezuela. Anthurium clavigerum represents a species of wide distribution. On Cerro Pirre, it grows along the lowland semideciduous forest and in mid-elevation evergreen forests, between 90 and 800 m. It is very common to observe adult individuals on trees associated with the banks of rivers and streams.

description: When it comes to modes of communication, sarcasm may be most commonly associated with the angst-ridden adolescent or rebellious teenager. While the use of sarcasm is certainly not exclusive to these communities, such a comparison may not be entirely without reason. Etymologically, the word ‘sarcasm’ is derived from the Greek sarkazein, meaning “to speak bitterly or sneer”, or, more literally, “to tear flesh” (“sarcasm,” 2014). Sarcasm, then, is far from a benign feature of language, and there appears to be an inherent acerbity, or even a note of provocation, located within. Indeed, sarcasm has been referred to in research in terms such as “jocular aggression” (Pogrebin & Poole, 1988, p. 192) or “humorous aggression” (Ducharme, 1994, p. 51). This does not mean it is rarely or fastidiously used, however. In spite of any innate or perceived aggression, sarcasm is, in fact, quite a common feature in spoken discourse. Studies have placed the use of sarcastic language at roughly 8% of conversational turns (Gibbs, 2000, p. 5; Tannen, 1984, p. 131), so it is certainly a notable and oft-tapped linguistic resource. As technology progresses, however, computer-mediated communication is becoming increasingly common and, with the advent of social media (Twitter, Facebook, Whatsapp, etc.), increasingly conversational. In this vein, perhaps sarcasm’s role as a feature of primarily spoken discourse needs to be re-evaluated. In this paper, I hope to offer a descriptive analysis of sarcasm as produced in an exclusively digital space, as well as bring attention to a novel use of sarcasm specific to this environment: sarcasm used as a pseudo-argument.

Journalism--Technological innovations

description: The relationship between technology platforms and news publishers has endured a fraught 18 months. Even so, the external forces of civic and regulatory pressure are hastening a convergence between the two fields at an accelerated rate beyond what we saw when we published our first report from this study, “The Platform Press: How Silicon Valley Reengineered Journalism,” in March 2017. Journalism has played a critical part in pushing for accountability into the practices of companies such as Facebook, Google and Twitter, yet newsrooms are increasingly oriented toward understanding and leveraging platforms as part of finding a sustainable future. In the latest phase of our multi-year research into the relationship between platforms and publishers, we found that despite negative rhetoric and sentiment in newsrooms toward technology companies, there is a rapid and ongoing merging in the functions of publishers and platforms, and an often surprisingly high level of involvement from platform companies in influencing news production.

This species is distinguished by its oblongelliptic and glandular-punctate blades, as well as by its yellow-greenish spadices with thickened tepals. On Cerro Pirre, A. crassitepalum is very similar to A. terryae Croat, but the latter species differs by its very short petioles and flowers lacking thickened tepals. Distribution and ecology. This species is endemic to the Darien Province. In the study area, it is found only in cloud forests that are above 1100 m. During the samplings, no individuals of this species were observed.

Advertising--Technological innovations

description: Advertising technology has built a massive technical infrastructure. The technology and motivations of advertising undergird the economy of the internet. News sites are no exception. The information we seek about our world is underpinned with, and shaped by, advertising and its needs. Journalists need to know more about these technologies, how they work, and how they influence the practice, distribution, and perception of journalism. Advertising technology may threaten the reputation and economic viability of news publishers in various ways. Ad tech promotes a specific type of audience engagement, and its incentive structures have been shown to alter how news gets produced, potentially undermining readers’ trust in publishers to provide objective coverage. Ad tech’s push of user data through opaque systems, and in some cases deposit malware onto readers’ devices, threatens reader privacy and safety and can further damage publishers’ reputations. The slow load times and distracting user experience of display ads can hamper the performance of news websites and drive readers towards walled information gardens like private apps and social-media platforms. This may siphon audiences away from professional journalism outlets and may render them more vulnerable to manipulative information operations, patterns which academics and policy-makers are only beginning to under- stand. Policies around advertising on social platforms threaten to blur the line between news and political messaging, and may incentivize so-called “influencers” to bypass publishers entirely and create their own content. Search-engine companies, meanwhile, have been accused of exploiting their power over how users find and access information. In producing this report we were driven by a set of questions, including: What’s the relationship between news publishers and advertisers? What’s changing? What’s contested? And how does the contemporary arrangement of advertising, writers, readers, and devices influence the news?
Multiband Effects on Superconducting Instabilities Driven by Electron-Electron Interactions

description: We explore multiband effects on d-wave superconducting instabilities driven by electron-electron interactions. Our models on the two-dimensional square lattice consist of a main band with an extended Fermi surface and predominant weight from $d_{x^2-y^2}$ orbitals, whose orbital character is influenced by the admixture of other energetically neighbored orbitals. Using a functional renormalization group description of the superconducting instabilities of the system and different levels of approximations, we study how the energy scale for pairing and hence the critical temperature is affected by the band structure. We find that a reduction of orbital admixture as a function of the orbital energies can cause a $T_c$ enhancement although the Fermi surface becomes more curved and hence less favorable for antiferromagnetic spin fluctuations. While our study does not allow a quantitative understanding of the $T_c$ differences in realistic high-$T_c$ cuprate systems, it may reveal an underlying mechanism contributing to the actual material trends.

description: The research on the second language (L2) speaking assessment has been predominantly concerned with formal proficiency tests. However, with a growing interest in learning-oriented assessment (LOA), more researchers are interested in learner involvement in speaking assessment (Blanche & Merino, 1989; Luoma, 2004; Ocarson, 1989). Self- and peer-assessment of speaking, where learners evaluate the performance of their own and their peers, can be an exemplar of assessment with its primary purpose on learning (Chen, 2006, 2008; Ibersson, 2012; Saito, 2008; Topping & Ehly, 1998). Depending on the purpose, self- and peer-assessment can take various forms: a questionnaire on general speaking ability, a learning log for metacognitive reflection, or a classroom activity where learners use the same rating criteria as their teachers (Bachman & Palmer, 1989; Chen, 2008, Rivers, 2001).
The Higgs mass range from Standard Model false vacuum Inflation in scalar-tensor gravity

description: If the Standard Model is valid up to very high energies it is known that the Higgs potential can develop a local minimum at field values around $10^{15}-10^{17}$ GeV, for a narrow band of values of the top quark and Higgs masses. We show that in a scalar-tensor theory of gravity such Higgs false vacuum can give rise to viable inflation if the potential barrier is very shallow, allowing for tunneling and relaxation into the electroweak scale true vacuum. The amplitude of cosmological density perturbations from inflation is directly linked to the value of the Higgs potential at the false minimum. Requiring the top quark mass, the amplitude and spectral index of density perturbations to be compatible with observations, selects a narrow range of values for the Higgs mass, $m_H=126.0\pm 3.5$ GeV, where the error is mostly due to the theoretical uncertainty of the 2-loop RGE. This prediction could be soon tested at the Large Hadron Collider. Our inflationary scenario could also be further checked by better constraining the spectral index and the tensor-to-scalar ratio.

description: We re-derive the Schrödinger-Robertson uncertainty principle for the position and momentum of a quantum particle. Our derivation does not directly employ commutation relations, but works by reduction to an eigenvalue problem related to the harmonic oscillator, which can then be further exploited to find a larger class of constrained uncertainty relations. We derive an uncertainty relation under the constraint of a fixed degree of Gaussianity and prove that, remarkably, it is saturated by all eigenstates of the harmonic oscillator. This goes beyond the common knowledge that the (Gaussian) ground state of the harmonic oscillator saturates the uncertainty relation.

description: In the last decade, Central Asia has received intense engagement from the United States, Russia, and China. However, the strategic goals of these three powers have varied considerably. But to focus exclusively on the competing agendas of these external powers neglects the considerable political agency shown by the Central Asian states themselves over the last decade. The real story of the 'New Great Game' is that as Moscow, Washington, and Beijing have intensified their competition for influence, Central Asian governments have learned to more actively play one external suitor off against the other for their own narrow domestic political interests.

description: No abstracts are to be cited without prior reference to the author.Results of long-term ichthyoplankton investigations in the deep basins of the Baltic Sea during the period 1957 – 1996 were used to estimate the annual cod egg production on the three main spawning grounds: the Bornholm Basin, the Gdansk Deep, the Southern and Central parts of the Gotland Basin. After a period of continuously increasing egg production from 1961 to 1966, the inter-annual variability in cod egg production in the Bornholm Basin until 1980 manifested itself mainly by moderate fluctuations around an average value without obvious trends. A similar increase however until end of the 1960`s was observed also in the eastern basins, but interannual variability was much more pronounced with few strong peaks. After the drastic cod egg production decline in the beginning of the 1980’s on all cod spawning grounds a period of substantially increasing egg production values was only observed in the Bornholm Basin during the mid 1990`s, while a minor increase was detected in the Gdansk Deep in 1994, but not in the Gotland Basin. The comparison of the inter-annual cod egg production dynamics with dates of major inflows into the central Baltic Sea via the Danish Straits evidenced that these events exerted the major positive effect upon cod egg production and subsequent reproductive success especially in the eastern basins (most pronounced in the Central Gotland Basin) before the early 1980’s. Contrary, after the major inflow activity in 1993/1994 only the egg production in the Bornholm basin was significantly affected. Biological implications of inflow events on the eastern Baltic cod reproduction as well as implications for further applications of egg production time series are discussed.

This species is characterized by having intact and persistent cataphylls, narrowly ovate to ovate-triangular (more than twice as long as wide) and moderately coriaceous blades; creamy-white spadices and cucculate spathes. Some specimens had inusual larger blades, Croat 68700 C (35.9 × 6.0 cm), Hammel 16112 (41.0 × 7.0 cm), and Hartman 4685 (31.5 × 7.5 cm); however, the floral characteristics are similar to the rest of the specimens. At the study site, A. cucullispathum may be confused with juvenile individuals of A. ravenii Croat & R.A. Baker and Anthurium sp. 4, but both species differs due to the deciduous cataphylls in most of the nodes and by its reflexed and brittle spathes. Distribution and ecology. Colombia, Costa Rica, and Panama. On Cerro Pirre, this species generally grows in low and mid elevation areas, in the semideciduous and evergreen forests, below 1000 m.

description: This research report explores archiving practices and policies across newspapers, magazines, wire services, and digital-only news producers, with the aim of identifying the current state of archiving and potential strategies for preserving content in an age of digital distribution. Between March 2018 and January 2019, we conducted interviews with 48 individuals from 30 news organizations and preservation initiatives. What we found was that the majority of news outlets had not given any thought to even basic strategies for preserving their digital content, and not one was properly saving a holistic record of what it produces. Of the 21 news organizations in our study, 19 were not taking any protective steps at all to archive their web output. The remaining two lacked formal strategies to ensure that their current practices have the kind of longevity to outlast changes in technology. Meanwhile, interviewees frequently (and mistakenly) equated digital backup and storage in Google Docs or content management systems as synonymous with archiving. (They are not the same; backup refers to making copies for data recovery in case of damage or loss, while archiving refers to long-term preservation, ensuring that records will still be available even as formatting and distribution technologies change in the future.) Instead, news organizations have handed over their responsibilities as public stewards to third-party organizations such as the Internet Archive, Google, Ancestry, and ProQuest, which store and distribute copies of news content on remote servers. As such, the news cycle now includes reliance on proprietary organizations with increasing control over the public record. The Internet Archive aside, the larger issue is that their incentives are neither journalistic nor archival, and may conflict with both. While there are a number of news archiving initiatives being developed by both individuals and nonprofits, it is worth noting that preserving digital content is not, first and foremost, a technical challenge. Rather, it’s a test of human decision-making and a matter of priority. The first step in tackling an archival process is the intention to save content. News organizations must get there. The findings of this study should be a wakeup call to an industry fond of claiming that democracy cannot be sustained without journalism, one which anchors its legitimacy on being a truth and accountability watchdog. In an era where journalism is already under attack, managing its record and future are as important as ever. Local, independent, and alternative news sources are especially at risk of not being preserved, threatening to leave critical exclusions in a record that will favor dominant versions of public history. As the sudden Gawker shutdown demonstrated in 2016, content can be confiscated and disappear instantly without archiving practices in place.
The role of connexin 43 in B cell receptor signaling and the high throughput screen for novel B cell receptor signaling inhibitors
Creators: name: Choi, Kate
Publisher: name: University of British Columbia
Year: 2012

description: B cells migrate throughout the body, following chemokine gradients, to search for foreign antigens. When a B cell encounters an antigen-presenting cell (APC) bearing antigens that bind its B cell receptors (BCRs), it spreads across the surface of the APC to scan for additional antigens. This spreading is followed by contraction in which BCR microclusters recruit signaling enzymes and form an immune synapse. The resulting BCR signaling initiates an activation process in which B cells differentiate into antibody-producing plasma cells, which are directed to the bone marrow by chemokines, where they survive and produce antibodies for long periods of time. Both chemokine-induced B cell migration and BCR-induced cell spreading involve changes in the cytoskeleton. The gap junction protein connexin 43 (Cx43) regulates the migration of neuronal cells during brain development and interacts with many cytoskeletal-regulating partners. Previous work in our lab showed that Cx43 is important for BCR-induced spreading and chemokine-induced B cell migration, and for sustained activation of Rap1 GTPases, master regulators of cytoskeletal organization. However, the mechanism by which Cx43 enhances BCR- and chemokine-induced Rap1 activation was not known. The goal of my project was to determine whether Cx43 modulates all BCR signaling reactions, perhaps by acting on BCR-proximal signaling components, or whether it selectively regulates the activation of Rap1. I found that Cx43 influences the activation of certain BCR signaling pathways, specifically the PLCγ pathway, while having less effect on other targets of BCR signaling. This is the first evidence that Cx43 modulates BCR signaling and provides new insights into how Cx43 contributes to BCR-induced cytoskeletal regulation. BCR signaling is also important for B lymphoma cell survival and for the negative selection processes that eliminate autoreactive B cells. Although B cell depleting drugs have been used to treat B cell malignancies and B cell-mediated autoimmune diseases, there is variable efficacy. Small molecule inhibitors might be useful alternatives or additions to B cell depletion. Although several inhibitors of B cell signaling enzymes are being clinically tested, I have developed and optimized assay conditions to enable a large-scale screen for additional inhibitors of key components of BCR signaling pathways.

This species is recognized by its terrestrial habit, short internodes, semi-intact and persistent cataphylls, yellow tapered spadices, and white berries with lilac apex. Based on the characteristics mentioned, there are no species similar to A. ochranthum in the study area. It could be confused with A. dukei Croat, but differs in having massive leaves, ribbed petioles and very long creamy-yellow cataphylls. Distribution and ecology. Colombia, Costa Rica, Honduras, Nicaragua, and Panama. Compared with other terrestrial aroid species, A. ochranthum is possibly the most abundant in the semideciduous lowland forest of Cerro Pirre, but as elevation increases, its occurrence decreases. It is usual to observe this species along trails, rivers and streams, in shady places or in open areas.

description: We start reviewing Giulini's dynamical approach to Bargmann superselection rule proposing some improvements. We discuss some general features of the central extensions of the Galileian group used in Giulini's programme, focussing on the interplay of classical and quantum picture, without making any particular choice for the multipliers. Preserving other features of Giulini's approach, we modify the mass operator of a Galilei invariant quantum system to obtain a mass spectrum that is positive and discrete, giving rise to a standard (non-continuous) superselection rule. The model is invariant under time reversal but a further degree of freedom appears, interpreted as an internal conserved charge. (However, adopting a POVM approach a positive mass operator arises without assuming the existence of such a charge.) The effectiveness of Bargmann rule is shown to be equivalent to an averaging procedure over the unobservable degrees of freedom of the central extension of Galileo group. Moreover, viewing the Galileian invariant quantum mechanics as a non-relativistic limit, we prove that the above-mentioned averaging procedure giving rise to Bargmann superselection rule is nothing but an effective de-coherence phenomenon due to time evolution if assuming that real measurements includes a temporal averaging procedure. It happens when the added term $Mc^2$ is taken in the due account in the Hamiltonian operator since, in the dynamical approach, the mass $M$ is an operator and cannot be trivially neglected as in classical mechanics. The presented results are quite general and rely upon the only hypothesis that the mass operator has point-wise spectrum. These results explicitly show the interplay of the period of time of the averaging procedure, the energy content of the considered states, and the minimal difference of the mass operator eigenvalues.

description: In a number of educational contexts, it is common for two or more teachers to co-teach, or collaborate on-site together in a classroom. Despite the popularity of this arrangement, the body of discourse-analytic literature on co-teaching remains small. A good number of the studies that have been done have analyzed the participation structures of the collaborative interaction, examining the nuanced ways the teachers participate in and adhere to various aspects of turn-taking protocols while teaching (Bloome, Carter, Christian, Otto & Shuart-Faris, 2005). In the English as a foreign language (EFL) classroom, where a native English-speaking teacher and a local English teacher co-teach, a handful of studies (e.g., Butterfield & Bhatta, 2015; Lee, 2016; Luo, 2013) have looked at how two instructors navigate the well-known Initiation-Response-Feedback (IRF) sequence. This work has shown that the collaboration can add both complexity and versatility to the ways IRF unfolds. Other work looking at interaction between novice teachers paired with expert cooperating teachers (e.g., Roth, Tobin, Carambo and Dalland, 2005) has revealed that two instructors can make use of spatial resources to facilitate more seamless turn-taking.

description: No abstracts are to be cited without prior reference to the author.Dispersal of fish early life stages explains part of the annual recruitment strength, through interannual variability in spawning, transport and survival. These processes depend on the physical and biological environment affecting individuals at different stages of the life cycle. In the context of climate change, this environment will be impacted, modifying characteristics of the dispersal through changes in the hydrodynamics, temperature, prey and predator fields. We propose to test the sensitivity of the dispersal to three factors that could affect the dispersal kernel: (i) reduction of the larval drift duration, (ii) shift in the spawning timing, both factors being responses to a temperature increase, and (iii) change in the hydrodynamics. First, we defined indices to describe the dispersal of anchovy early life stages in the Bay of Biscay from simulations of Lagrangian trajectories in a 3D hydrodynamic model with realistic forcing. These indices can be gathered in three main groups: (i) mean transport (distance, orientation), (ii) parameters of inertia of the distribution, and (iii) parameters of aggregation of the distribution. Then these indices were calculated for model simulations covering the period 1996-2007 to test the effect of the first two factors, and for simulations using different scenarios of atmospheric forcing to test the third one. These forcing are based on regional projections for the end of the century assessed in the IPCC framework. Rather than proceeding to a still challenging downscaling from IPCC scenarios, we instead simply modified mean atmospheric parameter values (air temperature, wind, river run-off, and a combination of them) with respect to the IPCC likely projections over the Bay of Biscay, and run simulations using the modified atmospheric forcing of the two contrasting years 2001 and 2002. Results indicate that the dispersal kernel is sensitive to the three tested factors. Reduction of drift duration may decrease the mean drift distance and its variability, increasing retention around spawning locations. Earlier spawning may induce change in the drift direction in relation to the seasonality of the Bay of Biscay coastal circulation. Combined effects of temperature and wind increase has the major effect on the dispersal among the tested climate change scenarios. Further studies combining the different climate change effects, and accounting for more biologically explicit response of the individuals to their physical-biological environment, are necessary to better estimate the future change in the dispersal kernel.

Lexicographic works in the manuscripts of Timbuktu

Treatises of Arab lexicographers and lexicographic works in general have long been in circulation in the region of Timbuktu. The presentation sets to assess the Timbuktu manuscripts containing lexical descriptions to understand what subjects these manuscripts represent and in what languages they are written. Another topic is the question of influence of Arabic on sub-Saharan languages, with a focus on Arabic loan words in Songhay. On the examples of manuscripts from Mamma Haidara Library and Institute Ahmed Baba (IHERI-AB), it is demonstrated that the Timbuktu authors employed lexicographic approaches. For example, the manuscripts IHERI-AB 3776 allegedly attributed to Ahmed Baba (1556-1627), uses a format of a bilingual dictionary to describe 45 Arabic words in Songhay. Many of these words are special terms for herbs and spices and some are also explained in Arabic before being translated into Songhay.

الفكر المعجمي في مخطوطات تمبكت

د.إسماعيل زنغو برزي، أستاذ في جامعة بماكو؛ أ. سيدي إمام ميغا، باحث في معهد أحمد بابا

في الواقع، غني عن الذكر أن المعاجم  اللغوية متداولةُ عند أغلب الشعوب التي عرفت الحضارات القديمة، من أروبيين وهنود وفرس وعرب .. إلخ؛ ولكن مما لا مندوحة عنه أن أغلب هذه الشعوب السابقة تقدمت منذ فترة متعاقبة وربما طويلة في صناعة المعاجم، وقد رأينا بعض هذه المعاجم أحادية اللغة، وأخرى ثنائية، وثلاثية .. إلخ حسب هدف المؤلف وحاجة القراء.

وإذا تعلقت المسألة باللغات الأفريقية الكبرى فقد عرفت أيضا بعض الأدبيات المعجمية عبر أبجديات لاتينية في أغلبها ـ إن لم اقل كلها ـ منذ فترة وربما عرفت أغلبها ذلك بُعيد الاستقلال إلى يومنا هذا، فاعتمدت أغلبها ثنائية لغوية؛ ذلك أن مؤلفيها غربيون يستهدفون إلى خدمة أبنانئهم في الدرجة الأولى، ثم إلى خدمة أطر خاص من المثقفين الأفريقيين.

أما إذا تعلقت المسألة باللغة العربية المتجسدة في أبجديتها التي تمثل الاولى من نوعها في كتابة الثقافة والحضارة الافريقيين منذ قرون، فهل اتخذتها أو وظفتها مخطوطات تنبكت  ـ عبر ما يعرف بالمخطوطات الأعجمية  ـ في صناعة المعاجم للغات الأفريقية؟

إذا كان الجواب بنعم فما تلك اللغة؟ وما نوعية المعاجم المتاحة في المجال؟ وما حجم المعاجم المتداولة؟ وهل يمكن وجود تاريخ تقريبي لهذا النوع من المخطوطات؟

هذه مجموعة من الاسئلة  المطروحة التي يحاول البحث  الاجابة عنها.

description: The competition between Kitaev and Heisenberg interactions away from half filling is studied for the the hole-doped Kitaev-Heisenberg $t$-$J_K$-$J_H$ model on a honeycomb lattice. While the isotropic Heisenberg coupling supports a time-reversal violating d-wave singlet state, we find that the Kitaev interaction favors a time-reversal invariant p-wave superconducting phase, which obeys the rotational symmetries of the microscopic model, and is robust for $J_Hμ_c$.

Anthurium ramonense is characterized by having a rosette-epiphytic habit, conglomerate roots, short petioles, black glandular-punctate blades only on the lower surface and long inflorescences. In the study area this species can be confused with A. salvinii Hemsl., which differs in having ribbed petioles and cucculate cataphylls. Distribution and ecology. Colombia, Costa Rica, Nicaragua, and Panama. This species of wide distribution is common to observe it in the evergreen and semideciduous forests of Cerro Pirre. Generally, it has an epiphytic habit, but when it falls from the branches of the host trees, can develop an accidental terrestrial habit.

description: Esterel is an imperative synchronous programming language for the design of reactive systems. Esterel* extends Esterel with a non-instantaneous jump instruction (compatible with concurrency, preemption, etc.) so as to enable powerful source-to-source program transformations, amenable to formal verification. In this work, we propose an approximate reachability algorithm for Esterel* and use its output to remove dead code. We prove the correctness of our techniques.

On Cerro Pirre, this species is very similar to A. ravenii Croat & R.A. Baker (for differences, see the notes on the latter species). Distribution and ecology. Colombia and Panama. In the study area, the populations of this species occur mainly in the transition area between the submontane and montane forest, which is approximately between 1050 and 1100 m. Individuals can also be seen sporadically in the montane forest (> 1100 m). Apparently this species has a preference for slightly open areas with exposure to direct light of the sun.
