PHP is a widely used open source scripting language that allows web developers to create dynamic content that interacts with databases. Some key points:
- PHP code is executed on the server-side and can generate dynamic web page content. It allows creation of data-driven websites and web applications.
- PHP scripts can connect to and manipulate databases, collect form data, send and receive cookies, add/modify data, and encrypt data for security.
- It runs on most web servers, supports many databases, and can be used across platforms like Windows, Linux, and MacOS. PHP is free to download and use.
- Basic PHP syntax involves wrapping code within <?php ?> tags. It uses

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
2. What is PHP ?

12. • written in the C programming language
• Rasmus Lerdorf in 1994
• for use in monitoring his online resume and related personal
information.
• For this reason, PHP originally stood for
• "Personal Home Page"
• Because php libraries are already compiled and processed.
• Person request any php page in browser address bar that
request first go to server for example Apache is running on that
server.
• Server interpret php files and return back response in form of
HTML
13. Most software we use have been compiled. This means that its computer code has been
put through an application that translates it into a form your computer can understand.
After a program has been compiled, it's nearly impossible to modify it or see exactly how
it was created.
Open source software includes the source code along with the compiled code. People
who write open source software actually encourage others to customize it
Cross-platform software can run on most or all systems with little or no modification
14. Not limited to output HTML.
Abilities includes outputting images
PDF files and
even Flash movies
You can also output easily any text, such as XHTML and any other
XML file.
OUTPUT
17. In PHP, a variable starts with the $ sign,
followed by the name of the variable.
PHP has three different variable scopes:
local
global
Static
PHP Variables
<!DOCTYPE html>
<html>
<body>
<?php
$txt = "W3Schools.com";
echo "I love " . $txt . "!";
?>
</body>
</html>
18. echo and print are more or less the
same. They are both used to output
data to the screen.
The differences are small: echo has no
return value while print has a return
value of 1 so it can be used in
expressions. echo can take multiple
parameters (although such usage is
rare) while print can take one
argument. echo is marginally faster
than print.
PHP echo & Print Statements
<?php
echo "<h2>PHP is Fun!</h2>";
echo "Hello world!<br>";
echo "I'm about to learn
PHP!<br>";
echo "This ", "string ", "was
", "made ", "with multiple
parameters.";
?>
19. PHP supports the following data types:
String
Integer
Float (floating point numbers - also called double)
Boolean
Array
Object
NULL
Resource
PHP Data Types
20. Operators are used to perform operations on variables and values.
PHP divides the operators in the following groups:
Arithmetic operators
Assignment operators
Comparison operators
Increment/Decrement operators
Logical operators
String operators
Array operators
PHP Operators
21.
22. A function name can start with
a letter or underscore (not a
number).
PHP Functions
<?php
function familyName($fname) {
echo "$fname Refsnes.<br>";
}
familyName("Jani");
familyName("Hege");
familyName("Stale");
familyName("Kai Jim");
familyName("Borge");
?>
23. The PHP superglobals $_GET and $_POST are used to collect
form-data.
PHP Form Handling
<html>
<body>
Welcome <?php echo $_GET["name"]; ?><br>
Your email address is: <?php echo
$_GET["email"]; ?>
</body>
</html>
<html>
<body>
Welcome <?php echo $_POST["name"];
?><br>
Your email address is: <?php echo
$_POST["email"]; ?>
</body>
</html>
24. Both GET and POST create an array
$_GET is an array of variables passed to the current script via the URL
parameters.
$_POST is an array of variables passed to the current script via the HTTP
POST method.
Information sent from a form with the GET method is visible to everyone.
Information sent from a form with the POST method is invisible to others.
GET VS POST
25. to open files is with the fopen() function.
The fread() function reads from an open
file.
The fclose() function is used to close an
open file.
The fgets() function is used to read a single
line from a file.
The feof() function checks if the "end-of-
file" (EOF) has been reached.
The fgetc() function is used to read a single
character from a file.
PHP File Open/Read/Close
<?php
$myfile =
fopen("webdictionary.txt",
"r");
// some code to be
executed....
fclose($myfile);
?>
26. The fopen() function is also used to create a file.
The fwrite() function is used to write to a file.
The first parameter of fwrite() contains the name of the file to
write to and the second parameter is the string to be written.
PHP File Create/Write
27. Several predefined variables in PHP are "superglobals", which means that they are always accessible,
regardless of scope - and you can access them from any function, class or file without having to do
anything special.
The PHP superglobal variables are:
$GLOBALS
$_SERVER
$_REQUEST
$_POST
$_GET
$_FILES
$_ENV
$_COOKIE
$_SESSION
PHP Superglobal
28. A cookie is often used to identify a user. A
cookie is a small file that the server
embeds on the user's computer. Each
time the same computer requests a page
with a browser, it will send the cookie too.
With PHP, you can both create and
retrieve cookie values.
A cookie is created with the setcookie()
function.
PHP Cookie
<?php
$cookie_name = "user";
$cookie_value = "John Doe";
setcookie($cookie_name,
$cookie_value, time() +
(86400 * 30),"/"); // 86400 = 1 day
?>
<html>
<body>
<?php
if(!isset($_COOKIE[$cookie_name])) {
echo "Cookie named '" .
$cookie_name . "' is not set!";
} else {
echo "Cookie '" . $cookie_name
. "' is set!<br>";
echo "Value is:
" . $_COOKIE[$cookie_name];
}
?>
</body>
</html>
29. A session is a way to store
information (in variables) to be
used across multiple pages
A session is started with the
session_start() function.
Session variables are set with the
PHP global variable: $_SESSION.
PHP Sessions
<?php
// Start the session
session_start();
?>
<!DOCTYPE html>
<html>
<body>
<?php
// Set session variables
$_SESSION["favcolor"] = "green";
$_SESSION["favanimal"] = "cat";
echo "Session variables are set.";
?>
</body>
</html>
30. PHP 5 and later can work with a MySQL database using:
MySQLi extension (the "i" stands for improved)
PDO (PHP Data Objects)
PDO will work on 12 different database systems, where as
MySQLi will only work with MySQL databases.
