    1. Surprisingly, quorum sensing promotes V. cholerae virulence factor expression and biofilm formation at low cell density and represses these traits at high cell density

      Vibrio cholerae QS (high density) inhibits biofilm and virulence

    2. Quorum sensing is essential for chronic P. aeruginosa respiratory infection because it controls adhesion, biofilm formation, and virulence factor expression

      Psuedomonas aeruginosa QS induces biofilm formation

    1. i-1 times for each i.

      R^(i) = R⋅R^(i-1)--- remember: you already have an R as a "coefficient"

      so: R^(0) = R⋅R^(-1) ??? Wait, then what's R^(-1) which then must exist by this definition?

      ANS:?

    1. An application of a user-defined function substitutes some values forthe corresponding parameters in the definition’s expression

      The application of a function will substitute some values in the place of the corresponding parameters in the function's definition (body) expression.

    2. the computed final result is the same as for other choices.

      if you were to do this a different way you would get the same result?

    1.   #map { height: 100%; }

      isn't html and body already declared as having height of 100%?

      Why isnt' that enough?


      ANS :

      "Note that divs usually take their width from their containing element, and empty divs usually have 0 height. For this reason, you must always set a height on the

      <div> explicitly."

      </div>

      the thing that the arrow goes down to

      are those objects that extend the properties of the objects above it?

    1. //Instance Variables private String name = ""; private String sex = ""; private int max_hit_points = 0; private current_hit_points = 0;

      //Constructors Character (String name, String sex, int max_hit_points, int current_hit_points){ this.name = name; this.sex = sex; this.max_hit_points = max_hit_points; this.current_hit_points = current_hit_points; } Character ( ){ this.name = "harvester"; this.sex = "male"; this.max_hit_points = 50; this.current_hit_points = 0; }

      The name, sex, and max_hit_points given to the Character constructor won't override what's in the class by default, will it?

    1. label.repaint();

      you cannot access the JFrame from in here esp. using this

    2. this.addMouseListener (new MouseAdapter() {
      

      adding a mouse listener to THE WINDOW

    1. The statements below placed in the main() method runs the GUI (Graphical User Interface) from an event dispatching-thread. GUIs should ve invoked from an event-dispatching thread to ensure that each event-handler finishes executing before the next one executes. Thorough coverage of this topic is beyond the scope of this lesson. However, the code shown is needed in every application that implements a Swing GUI.

    2. A Swing timer (an instance of javax.swing.Timer) fires one or more action events after a specified delay. You can use Swing timers to perform a task repeatedly. For example, you might perform animation or update a component that displays progress toward a goal.

      Swing timers are very easy to use. You create the timer, and you specify an action listener to be notified when the timer "goes off". The actionPerformed() method in this listener should contain the code for whatever task you need to be performed. To start the timer, call its start() method. In our example, the actionPerformed() method contains a call to the repaint() method. Basically this is how the paint() method is being called. We don't call paint() directly, we call repaint(), and the Java environment will run the paint() method.

    1. It makes sense that we do "addActionListener(this)" because this object is an action listener (We have implemented it, and made it a child of ActionListener. Someone (who?) calls actionPerformed upon an action event )

    1. g2.drawString("Hello world", 100, 100)

      How does g2 know where to paint? Is it because it is in the JFrame object? And within the paint method?
