The Flash 2016 68

The Flash has arrived back in his home of Central City to discover somethingÉoff. The people are all acting strangely, including his friends and colleaguesÑbut before Barry can figure out why, the entire Central City PD attacks! At last the great trick is revealed: the Trickster now rules supreme! With Iron Heights as his fun-house base of operations, Trickster plunges the entire city into madnessÑand the Flash is powerless to save them!

Flash! presents a fascinating cultural history of flash photography, from its mid-nineteenth century beginnings to the present day. All photography requires light, but the light of flash photography is quite distinctive: artificial, sudden, shocking, intrusive, and extraordinarily bright. Associated with revelation and wonder, it has been linked to the sublimity of lightning. Yet it has also been reviled: it's inseparable from anxieties about intrusion and violence, it creates a visual disturbance, and its effects are often harsh and create exaggerated contrasts. Flash! explores flash's power to reveal shocking social conditions, its impact on the representation of race, its illumination of what would otherwise remain hidden in darkness, and its capacity to put on display the most mundane corners of everyday life. It looks at flash's distinct aesthetics, examines how paparazzi chase celebrities, how flash is intimately linked to crime, how flash has been used to light up - and interrupt - countless family gatherings, how flash can 'stop time' allowing one to photograph rapidly moving objects or freeze in a strobe, and it considers the biggest flash of all, the atomic bomb. Examining the work of professionals and amateurs, news hounds and art photographers, photographers of crime and of wildlife, the volume builds a picture of flash's place in popular culture, and its role in literature and film. Generously illustrated throughout, Flash! brings out the central role of this medium to the history of photography and challenges some commonly held ideas about the nature of photography itself.

This book presents the basics of both NAND flash storage and machine learning, detailing the storage problems the latter can help to solve. At a first sight, machine learning and non-volatile memories seem very far away from each other. Machine learning implies mathematics, algorithms and a lot of computation; non-volatile memories are solid-state devices used to store information, having the amazing capability of retaining the information even without power supply. This book will help the reader understand how these two worlds can work together, bringing a lot of value to each other. In particular, the book covers two main fields of application: analog neural networks (NNs) and solid-state drives (SSDs). After reviewing the basics of machine learning in Chapter 1, Chapter 2 shows how neural networks can mimic the human brain; to accomplish this result, neural networks have to perform a specific computation called vector-by-matrix (VbM) multiplication, which is particularly power hungry. In the digital domain, VbM is implemented by means of logic gates which dictate both the area occupation and the power consumption; the combination of the two poses serious challenges to the hardware scalability, thus limiting the size of the neural network itself, especially in terms of the number of processable inputs and outputs. Non-volatile memories (phase change memories in Chapter 3, resistive memories in Chapter 4, and 3D flash memories in Chapter 5 and Chapter 6) enable the analog implementation of the VbM (also called “neuromorphic architecture”), which can easily beat the equivalent digital implementation in terms of both speed and energy consumption. SSDs and flash memories are strictly coupled together; as 3D flash scales, there is a significant amount of work that has to be done in order to optimize the overall performances of SSDs. Machine learning has emerged as a viable solution in many stages of this process. After introducing the main flash reliability issues, Chapter 7 shows both supervised and un-supervised machine learning techniques that can be applied to NAND. In addition, Chapter 7 deals with algorithms and techniques for a pro-active reliability management of SSDs. Last but not least, the last section of Chapter 7 discusses the next challenge for machine learning in the context of the so-called computational storage. No doubt that machine learning and non-volatile memories can help each other, but we are just at the beginning of the journey; this book helps researchers understand the basics of each field by providing real application examples, hopefully, providing a good starting point for the next level of development.

Beginning: “The Flash Age”! The story we’ve been building toward since issue #50 comes to a head! While a supercharged Speed Force wreaks havoc on Barry Allen’s life, a new threat appears on the horizon in the form of the deadly Paradox. Destined to destroy the Flash’s legacy, Paradox sends his herald, Godspeed, to trap the Flash family! Plus, in this special anniversary issue: tales from across the generations of super-speedsters by an all-star lineup of writers and artists!

“LIGHTNING STRIKES TWICE” part seven! Still reeling from Godspeed’s devastating attack, the beleaguered Flash realizes that to defeat this menacing new foe he must take away the Speed Force power from Central City’s new citizen speedsters. There’s only one problem: they don’t want to give it back.

“The Flash Year One” finale! This oversize anniversary issue marks the end of Barry Allen’s journey to become the Flash—but at what cost? The Turtle’s final play will challenge our hero in every way possible, and by the end of the battle, a Flash will be born—and a Flash will die! Also in this issue, witness Lex Luthor’s offer to Captain Cold, whose icy vengeance waits for the Flash just around the corner…“The Flash Year One” finale!

As the dust settles in the wake of ÒFLASH WAR,Ó the Flash and his family of speedsters try to pick up the pieces of whatÕs left. But bad blood can run deep. This is the one race the Flash Family canÕt win!

“DATE NIGHT”! It’s holiday season in Central City and Barry Allen goes on a date with a brand new sweetheart. But things never go as planned for The Flash, who finds himself saddled with an unexpected wingman.
