JQuery is a JavaScript library that simplifies common JavaScript tasks like selecting parts of a page, modifying appearances and content, adding animations and handling events. It works by selecting DOM elements and wrapping them in JQuery objects, allowing methods to be called on the selection. Key features include CSS-style selectors to find elements, chaining of method calls, and events to trigger functions. The document.ready() method runs code when the page DOM is loaded but before images.

JavaScript - Chapter 12 - Document Object Model
What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents:
"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
The W3C DOM standard is separated into 3 different parts:
Core DOM - standard model for all document types
XML DOM - standard model for XML documents
HTML DOM - standard model for HTML documents
The HTML DOM (Document Object Model)
When a web page is loaded, the browser creates a Document Object Model of the page.
The HTML DOM model is constructed as a tree of Objects.
With the HTML DOM, JavaScript can access and change all the elements of an HTML document.
ReactJS.ppt
React JS is a library for creating user interfaces that focuses on the view layer. It uses a virtual DOM which is a JavaScript object representation of real DOM elements to efficiently update and render components when data changes. Components can contain subcomponents in a nested structure similar to HTML. Data flows through states that store application data and react to changes, and props are used to pass data between components. The DOM represents elements in a web page as JavaScript objects that can be manipulated. React components can be functions or classes, accept arbitrary inputs via props, and return React elements describing what should appear on screen.

Ajax Performance Tuning and Best Practices
Ajax Performance Tuning and Best Practices
Perhaps the most primary motivation to develop Ajax application is to have better user experience hence how to achieve the optimized response time becomes an important aspect in Ajax performance optimization. In this session, we will focus on discussing the improvement of the network transfer time and the JavaScript processing time as the server response is already generally well understood. We will use an Ajax framework case study to show how an Ajax optimization process can be used to optimize the performance. During the optimization process, we will demonstrate how to measure the performance, how to determine the bottlenecks and how to resolve the problems by applying various best practice. Various tools like NetBeans, Firebug, and YSlow will be illustrated to show when to use what and how to use them. The list of Ajax Performance tuning tips on combining CSS and JavaScript resources, setting the correct headers, using minifed JavaScript, GZip contents, and Strategically placing of CSS links and JavaScript tags will be discussed in the session.
Intermediate level Ajax and Enterprise developers can really benefit from this session.
After the session, the audience will be able to:
-apply Ajax Performance Optimization process
-choose the right tool and use them
-lleverage various best practice and performance tuning tips

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

Signatures of wave erosion in Titan’s coasts
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.

Anti-Universe And Emergent Gravity and the Dark Universe
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.

- 2. JQuery • Powerful JavaScript library – Simplify common JavaScript tasks – Access parts of a page • using CSS or XPath-like expressions – Modify the appearance of a page – Alter the content of a page – Change the user’s interaction with a page – Add animation to a page – Provide AJAX support – Abstract away browser quirks
- 3. Introductory Sample <html> <body> <h1>Cities of the World</h1> <dl> <dt>Paris</dt><dd>Chic, fashionable, expensive rude</dd> <dt>Sydney</dt><dd>Opera house but no culture, Mardi Gras, fireworks</dd> </dl> </body> </html> h1 {font-size: 2.5em; margin-bottom: 0;} .emphasize {font-style: italic; color:red;}
- 4. Basic JQuery • Selecting part of document is fundamental operation • A JQuery object is a wrapper for a selected group of DOM nodes • $() function is a factory method that creates JQuery objects • $(“dt”) is a JQuery object containing all the “dt” elements in the document
- 5. Basic JQuery • .addClass() method changes the DOM nodes by adding a ‘class’ attribute – The ‘class’ attribute is a special CSS construct that provides a visual architecture independent of the element structures • $(“dt”).addClass(“emphasize”) will change all occurrences of <dt> to <dt class=“emphasize”> • See also .removeClass()
- 6. Basic JQuery • To make this change, put it in a function and call it when the document has been loaded and the DOM is created function doEmph(){$(“dt”).addClass(“emphasize”)} <body onLoad=“doEmph()”> • We had to alter the HTML (bad) • Structure and appearance should be separated! • Also, onLoad waits until all images etc are loaded. Tedious.
- 7. Basic JQuery • JQuery provides an independent scheduling point after DOM is created and before images are loaded – $(document).ready(doEmph); • No HTML mods required. All done in script. • Better solution: – $(document).ready(function(){ $(“dt”).addClass(“emphasize”) }); <html><head> <script src="jquery.js" type="text/javascript"></script> <script src="test.js" type="text/javascript"></script> …
- 8. JQuery Selectors • CSS p element name #id identifier .class classname p.class element with class p a anchor as any descendant of p p > a anchor direct child of p
- 9. JQuery Selectors • XPath /html/body//div paths a[@href] anchor with an href attr div[ol] div with an ol inside //a[@ref='nofollow'] any anchor with a specific value for the ref attribute
- 10. JQuery Filters p:first first paragraph li:last last list item a:nth(3) fourth link a:eq(3) fourth link p:even or p:odd every other paragraph a:gt(3) or a:lt(4) every link after the 4th or up to the fourth a:contains(‘click’) links that contain the
- 11. Example • JQuery uses chaining as follows $(‘a:contains("ECS")’). parent(). addClass("emphasize")
- 12. JQuery Events • bind(eventname, function) method – ‘click’ – ‘change’ – ‘resize’ • $(“a[@href]”).bind(‘click’,function(){ $(this).addClass(‘red’);});
- 13. Other JQuery Effects • .css(‘property’, ‘value’) • .css({‘prop1’:‘value1’, ‘prop2’:’value2’…}) • E.g. .css(‘color’, ‘red’) • .hide(speed) or .show(speed) – Where speed is ‘slow’, ‘normal’ or ‘fast’
- 14. More JQuery Changes DOM • .attr({‘name’, ‘value’}) – sets a new attribute (or many) • $(‘<i>hello</i>’) – Creates a new element • $(‘<i>hello</i>’).insertAfter(‘div.chapter p’); – Creates element and inserts it into the document • .html() or .text() or .empty() will replace matched elements with newly created elements
