There is increasing pressure to protect computer networks against unauthorized intrusion, and some work in this area is concerned with engineering systems that are robust to attack. However, no system can be made invulnerable. Data Analysis for Network Cyber-Security focuses on monitoring and analyzing network traffic data, with the intention of preventing, or quickly identifying, malicious activity.Such work involves the intersection of statistics, data mining and computer science. Fundamentally, network traffic is relational, embodying a link between devices. As such, graph analysis approaches are a natural candidate. However, such methods do not scale well to the demands of real problems,...
From the mega-bestselling creator of Heartstopper, a must-have novella in which Heartstopper's lead characters, Nick and Charlie, face one of their biggest challenges yet. Absence makes the heart grow fonder... right? Everyone knows that Nick and Charlie love their nearly inseparable life together. But soon Nick will be leaving for university, and Charlie, a year younger, will be left behind.

What will it take for Nick and Charlie to defy the odds?
Everyone is shocked when Catherine, a pregnant surrogate, goes missing—from the gay couple whose child she was carrying, to her estranged sister Eva-Sue, to her college friend Marcus Agaston, now a Dallas reporter. When Catherine’s body appears on the shoreline of Lake Ray Hubbard seven days later, Marcus vows to find the killer. However, Marcus has a dark past—one that his husband Sam, a successful lawyer, knows nothing about. And the more clues Marcus uncovers about the killer’s identity, the more connections he discovers between a history he’d rather forget and Catherine’s mysterious murder. Someone will stop at nothing to keep their secrets buried, and as Marcus gets closer to finding the killer, a shocking revelation proves you can’t trust anyone.

Now he has an active role in the Presence, a Tracer trapped in the Plexus, where he is charged with dispatching evil souls to hell without actually falling to the dark side himself. The two groups in the Plexus, Tracers and Hailites, are in charge of balancing the power of good. However, the peace between them is waning. Will that end in disaster? To make matters worse, a new partner is introduced to the Plexus. Bonnie, a Hailite, may be all that Nicholas needs to survive his past and future. Will his interest in Bonnie cause the Presence to fall to the demons? Or will Bonnie be exactly what Nicholas needs-a Soul Mate? In this fast-paced, thought-proving book, you'll follow along as the unseen battle rages on...

Prior to the stock market crash in 1929, Holland was a prosperous country where its people enjoyed secure futures-or so they thought. After the world's economic collapse, millions were forced into a poverty-stricken existence where every day was a struggle to survive. A Lousy Start shares one family's vivid impressions of living in Holland during the Great Depression and the lasting impact those experiences had on their lives. At the beginning of the twentieth century, Arie Demerwe worked hard and was paid very little, but still managed to put food on his table. Sent to fight in the war of 1918, Arie finally returned to his hometown where he began working again-only to see everything change again after the end of World War I. As the people of Holland enjoyed wealth they assumed would last forever, dark changes loomed ahead. When the sun rose on October 23, 1929, no one had a clue that tragedy would strike by day's end. For the next ten years, a hostile world would transform even the most religious people into thieves and liars. As one family fought to stay alive in a bleak existence, each of them learned valuable life lessons they would carry with them forever.

Cyber-security is a matter of rapidly growing importance in industry and government. This book provides insight into a range of data science techniques for addressing these pressing concerns.The application of statistical and broader data science techniques provides an exciting growth area in the design of cyber defences. Networks of connected devices, such as enterprise computer networks or the wider so-called Internet of Things, are all vulnerable to misuse and attack, and data science methods offer the promise to detect such behaviours from the vast collections of cyber traffic data sources that can be obtained. In many cases, this is achieved through anomaly detection of unusual behaviour against understood statistical models of normality.This volume presents contributed papers from an international conference of the same name held at Imperial College. Experts from the field have provided their latest discoveries and review state of the art technologies.
"T'was the night before Christmas, when all through the house Not a creature was stirring-not even a mouse." This timeless poem is so well known to children and so often recited by adults it is virtually a part of our common heritage. Written on Christmas Eve in 1822-in a horse-drawn sleigh with jingling bells according to legend-it evokes the excitement and good cheer of Christmas Eve like no other work of American literature. Paired with Thomas Nast's drawings of St. Nicholas, from which we derive the classic image of Santa Claus, this lovely edition may well become the quintessential American Christmas book for children of all ages.
