Second Sister
by Chan Ho-KeiA reclusive Hong Kong PI and hacker investigates a teenager’s mysterious death in this technological thriller by the author of The Borrowed.A schoolgirl—Siu-Man—has committed suicide, leaping from her twenty-second floor window to the pavement below. Siu-Man is an orphan and the librarian older sister who’s been raising her refuses to believe there was no foul play—nothing seemed amiss. She contacts a man known only as N.—a hacker, and an expert in cybersecurity and manipulating human behavior. But can Nga-Yee interest him sufficiently to take her case, and can she afford it if he says yes?What follows is a cat and mouse game through the city of Hong Kong and its digital underground, especially an online gossip platform, where someone has been slandering Siu-Man. The novel is also populated by a man harassing girls on mass transit; high school kids, with their competing agendas and social dramas; a Hong Kong digital company courting an American venture capitalist; and the Triads, market women and noodle shop proprietors who frequent N.’s neighborhood of Sai Wan. In the end it all comes together to tell us who caused Siu-Man’s death and why, and to ask, in a world where online and offline dialogue has increasingly forgotten about the real people on the other end, what the proper punishment is.“Readers will savor every twist and turn of Chan Ho-Kei’s tour de force. . . . Second Sister is a masterclass on the vagaries of our digital age.” —Criminal Element“[A] clever, twisty novel. . . .

Second-Order Photogalvanic Photocurrents in 2D Materials (SpringerBriefs in Applied Sciences and Technology)
by Ting Yu Mustafa EginligilThis book highlights the photogalvanic effects at low dimensions, surfaces, and interfaces, more specifically 2D materials, such as graphene and monolayer transition metal dichalcogenides. Although the phenomenology of the photogalvanic effects, which can be simply seen as photoresponse nonlinear-in-electric field, have been well-established, the microscopic understanding in each material system may vary. This book is a quick reference and a detailed roadmap starting from phenomenology and continuing with the ultimate low dimensional materials, in which the photogalvanic effects can offer a rich platform at the second-order response to an electric field. A general phenomenology of photogalvanic effect is provided in the first chapter, together with the photon drag effect which also generates a photocurrent like the photogalvanic effect, but with some distinct features, as well as somewhat puzzling similarities. Next two chapters explain these effects in graphene, starting with a necessary related background on graphene, then a particular focus on its specific phenomenology, microscopic theory, and experimental results. In a similar fashion, in chapters four and five, a necessary background for the photogalvanic effects in monolayer transition metal dichalcogenides, with symmetry analysis, microscopic theory, and experimental results is presented, along with the Berry curvature dependent photocurrent, which can also play an important role in 2D semiconductors. The second-order photogalvanic effects that have been covered so far in graphene and monolayer transition metal chalcogenides have already excited the 2D semiconductor optoelectronic research community by several means. It seems that the interests on the photogalvanic effects will continue to escalate in near future.

Secondary Agriculture: Sustainability and Livelihood in India
by Syed Sheraz Mahdi F. A. Bahar M. Anwar BhatThis book on ‘Secondary Agriculture’ discusses the goal of doubling farmers’ incomes. The term ‘secondary’ has a bearing on climate change adaptation and its mitigation, small farm viability and profitability, food security, nutrition, sustainable utilization of natural resources, and optimal usage of produce from primary agriculture and farm incomes. Promoting secondary agriculture has implications on attaining sustainable development goals, which aim to connect primary, secondary and tertiary sectors by using slack/idle factors of production, such as land and labour, contributing to primary agriculture production, capturing ‘value’ in primary agricultural activities, and generating additional income at the enterprise level. In context to same, the chapters of this book have been designed to promote secondary agriculture through low-cost skills and technology applications in agriculture and by upscaling knowledge via integrating primary, secondary and tertiary sectors of agriculture. The motivation behind this book is to address the challenges of biotic and abiotic stresses facing the farming community; to increase farmers income through low-cost skills and technology applications in agriculture; to upscale knowledge by integrating primary, secondary and tertiary sectors of agriculture. The food processing sector in India is still in a nascent stage with only 8 per cent of the produce being processed as against 80-98 per cent in case of high-income countries (Government of India, 2008, 2010). The food processing sector is now receiving the boost with the annual growth of 13.2 per cent in registered food processing units during 2004-10 (Government of India, 2011). Against this backdrop, there is a strong need to strategically handle the situation in order to facilitate a self-sustainable and long-run growth of the sector, which is felt possible by focusing on Secondary Agriculture. Though not a panacea for all ailments of the primary sector, but it can definitely drive the growth.
Secondary Agriculture: Upgrading Agriculture for Jobs and Income
by Ashok Dalwai Ritambhara SinghA first of its kind, this authored book marshals data and logic that necessitate the agriculture sector to transcend beyond its conventional role of securing food, fodder, and feed. It examines India's growing working population and juxtaposes it with the declining labour demand in the secondary and tertiary sectors of the economy, on account of the deployment of disruptive suite of labour-substituting technologies. Therefore, the conventional developmental models that hypothesize the shifting of surplus manpower from agriculture to non-agricultural sectors may not stand the test of scrutiny in the twenty-first century. Hence, the need for remandating the agricultural sector to generate gainful jobs and supplementary incomes in an ecologically synchronous manner for sustainability. The book draws the readers' attention to the importance of bioeconomy and circular economy. To enhance the biologically dependent cumulative agri-output, it recommends the adoption of supplementary and complementary activities. These interventions, along with processing (food and non-food), aid in minimizing food loss, enhancing value capture in favour of the farmers and other value chain stakeholders, and creating gainful jobs and linked incomes resulting in higher enterprise-profits. This progresses the agricultural sector into a bioeconomy anchored around secondary agriculture. Agri-processing being integral to secondary agriculture can be practiced at various scales beginning from micro to small to medium to large. The book highlights both the scope for such enterprises in India and the challenges they are vulnerable to. In the context of sub-par levels of jobs and income in the farm sector, the book emphasizes on micro-enterprises, and suggests the clusterization of entrepreneurs and digitalization along the value chain to achieve competitiveness. The book also deliberates on market-led production matrix, and value chain-based extension services to meet the feedstock demands of secondary agriculture. This book is of relevance to a range of individuals and organizations concerned with agriculture. They include academics, researchers, professionals, universities, domestic & international organizations, bankers & financial institutions, FPOs, entrepreneurs, policymakers, and students.
Secondary Instabilities of Görtler Vortices in High-Speed Boundary Layers
by Jie RenThis thesis first reveals the mechanism of Görtler instabilities and then demonstrates how transitions at hypersonic flows can be effectively controlled (either promoted or suppressed) with Görtler or Klebanoff modes. It focuses on understanding and controlling flow transitions from mild laminar to fully turbulent flows at high speeds—aspects that have become crucial at the dawn of an incredible era, in which hypersonic vehicles are becoming available. Once this occurs, it will be possible to travel from Beijing to Los Angeles within just 2 hours, and we will all live in a genuinely global village—and not just virtually, but physically.Görtler instabilities have often been used to promote flow transition in hypersonic vehicles. However, how Görtler instabilities are excited and how they evolve in hypersonic flows are questions that have yet to be answered.
Secondary Metabolites Based Green Synthesis of Nanomaterials and Their Applications (Smart Nanomaterials Technology)
by Azamal HusenNanotechnology is gaining importance in every field of science and technology. Green synthesis of nanomaterials involves the use of microorganisms such as bacteria, fungi, viruses; and different lower and higher plants. Green synthesis of nanomaterials from plant extracts becoming popular in comparison to synthesis using microorganisms. Plant based-nanomaterials synthesis is easy, have no need to bring back from the culture medium, and is safe. Additionally, plant-based nanomaterials are eco-friendly, in comparison to physical and chemical modes of synthesis. Several lower and higher plants are rich in terms of secondary metabolites. These metabolites have been used as medicine in crude extract form or with some other formulations. They have been also used to isolate the bioactive compounds in modern medicine as well as in herbal medicine systems. Thus, phytochemicals present in the plant and their parts play an important role in nanomaterials synthesis, mainly due to the presence of a significant number of secondary metabolites, for instance, alkaloids, flavonoids, saponins, steroids, tannins, etc. Further, essential and aromatic oils have been also explored for nanomaterials synthesis, and they are also equally useful in terms of their various biological applications. These organic ingredients come from a wide range of plant components, such as leaves, stems, roots, shoots, flowers, bark, and seeds. Globally, the presence of different plants has shown a capability to produce huge and diverse groups of secondary metabolites. The functional groups present in the plant extract acts as capping and stabilizing agent. Most of the time, pure isolated bioactive compounds are more biologically active; hence scholars are focusing their research on the synthesis of nanomaterials using some particular class of secondary metabolites. Investigations have shown that the green synthesized nanomaterials were found to be more biologically active in comparison to chemically synthesized nanomaterials. These nanomaterials and or nanocomposites found different applications especially in drug delivery, detection and cure of cancer cells, diagnosis of a genetic disorder, photoimaging, and angiogenesis detection. They have also shown several applications in agricultural, horticultural as well as forestry sectors. The book in hand covers a wide range of topics as mentioned above. It incorporates chapters that the authors have skilfully crafted with clarity and precision, reviewing up-to-date literature with lucid illustrations. The book would cater to the need of graduate students as a textbook and simultaneously be useful for both novices and experienced scientists and or researchers working in the discipline of nanotechnology, nanomedicine, medicinal plants, plant science, economic botany, chemistry, biotechnology, pharmacognosy, pharmaceuticals, industrial chemistry, and many other interdisciplinary subjects. It should also inspire industrialists and policy makers associated with plant-based nano products.
Secondary Metabolites and Volatiles of PGPR in Plant-Growth Promotion
by R. Z. Sayyed Virgilio Gavicho UarrotaThis contributed volume explores how plant growth-promoting rhizobacterias (PGPR) provide a wide range of benefits to the plant. Further, it discusses the key roles PGPR play in nutrient acquisition and assimilation, improved soil texture, secreting, and modulating extracellular molecules. The book outlines how plant secondary metabolites are natural sources of biologically active compounds used in a wide range of applications, and surveys the significant role of volatile organic compounds (VOCs) in plant communication by mediating above- and below-ground interactions between plants and the surrounding organisms.This volume compiles research from leading scientists from across the globe, linking the translation of basic knowledge to innovative applied research. The book focuses on the following three categories: 1) understanding the secondary metabolites produced by PGPR, the signaling mechanisms and how they affect plant growth, 2) the plausible role of volatile organic compounds produced by PGPR, their role and the signaling mechanism for plant growth promotion, and 3) Applications of VOCs and secondary metabolites of PGPR for seed germination, plant growth promotion; stress tolerance and in-plant health and immunity.

Secondary Metabolites of Plant Growth Promoting Rhizomicroorganisms: Discovery and Applications
by Harikesh Bahadur Singh Estibaliz Sansinenea Carlos García-Estrada Chetan Keswani M. S. ReddyRecent changes in the pattern of agricultural practices from use of hazardous pesticides to natural (organic) cultivation has brought into focus the use of agriculturally important microorganisms for carrying out analogous functions. The reputation of plant growth promoting rhizomicroorganisms (PGPRs) is due to their antagonistic mechanisms against most of the fungal and bacterial phytopathogens. The biocontrol potential of agriculturally important microorganisms is mostly attributed to their bioactive secondary metabolites. However, low shelf life of many potential agriculturally important microorganisms impairs their use in agriculture and adoption by farmers. The focal theme of this book is to highlight the potential of employing biosynthesized secondary metabolites (SMs) from agriculturally important microorganisms for management of notorious phytopathogens, as a substitute of the currently available whole organism formulations and also as alternatives to hazardous synthetic pesticides. Accordingly, we have incorporated a comprehensive rundown of sections which particularly examine the SMs synthesized, secreted and induced by various agriculturally important microorganisms and their applications in agriculture. Section 1 includes discussion on biosynthesized antimicrobial secondary metabolites from fungal biocontrol agents. This section will cover the various issues such as development of formulation of secondary metabolites, genomic basis of metabolic diversity, metabolomic profiling of fungal biocontrol agents, novel classes of antimicrobial peptides. The section 1 will also cover the role of these secondary metabolites in antagonist-host interaction and application of biosynthesized antimicrobial secondary metabolites for management of plant diseases. Section 2 will discuss the biosynthesized secondary metabolites from bacterial PGPRs, strain dependent effects on plant metabolome profile, bio-prospecting various isolates of bacterial PGPRs for potential secondary metabolites and non-target effects of PGPR on microbial community structure and functions. Section 3 encompasses synthesis of antimicrobial secondary metabolites from beneficial endophytes, bio-prospecting medicinal and aromatic hosts and effect of endophytic SMs on plants under biotic and biotic stress conditions.

Secrecy and Science: A Historical Sociology of Biological and Chemical Warfare
by Brian BalmerIt is no secret that twentieth-century Britain was governed through a culture of secrecy, and secrecy was particularly endemic in military research and defence policy surrounding biological and chemical warfare. More generally, it is hard to exaggerate the role of secrecy in all past biological and chemical warfare programmes and several recent historical surveys of biological and chemical warfare research have emphasised that all state sponsored programmes, together with sub-state organised activities, were cloaked in utmost secrecy. Of these research programmes, Britain carried out one of the most significant in scale and scope in the twentieth century. Yet, partly because of the secrecy surrounding the programme, there is still little academic literature on its historical development. Equally, and despite secrecy being a pervasive feature of past and contemporary societies, social scientists and historians have paid relatively little scholarly attention to the nature, mechanics and effects of secrecy, particularly with regard to secrecy in relation to the production and governance of science and technology. Drawing on classical sociological writing on secrecy by Simmel, Merton and Shils this groundbreaking book by Brian Balmer draws on recently declassified documents to investigate significant episodes in the history of biological and chemical warfare. At the same time, it draws on more contemporary perspectives in science and technology studies that understand knowledge and social order as co-produced within heterogeneous networks of 'things and people' in order to develop a theoretical set of arguments about how the relationship between secrecy and science might be understood.
Secrecy, Covertness and Authentication in Wireless Communications: Physical Layer Security Approach (Wireless Networks)
by Xiaohong Jiang Yulong Shen Yuanyu ZhangThis book introduces the fundamentals of physical layer security (PLS) and demonstrates how a variety of PLS techniques can be applied to improve the security of wireless communication systems. In particular, this book covers three security aspects of wireless communications. It includes secrecy, i.e., preventing eavesdroppers from intercepting information from transmitted wireless signals, covertness, i.e., hiding the transmitted signals themselves from malicious wardens and authentication, i.e., authenticating the identities of communicating entities. When discussing the secrecy of wireless communication systems, this book covers physical layer secure communication in multiple-input multiple-out (MIMO) systems based on beamforming and precoding techniques, in relay systems based on link/relay selection and in large-scale random networks based on cooperative jamming. Regarding the covertness of wireless communication systems, this book introduces physical layer covert communication in relaying systems and MIMO systems. Also, when discussing authentication in wireless communication systems, this book introduces the implementation of physical layer authentication in MIMO systems based on channel features and/or radiometric features of transceivers. In addition, this book presents security-aware routing in wireless networks based on physical layer secure communication techniques.This book targets researchers in the fields of physical layer security and wireless communications security. Advanced-level students in electronic engineering or computer science studying these security topics will also want to purchase this book as a secondary textbook.
Secret Agent 666: Aleister Crowley, British Intelligence and the Occult
by Richard B. SpenceAleister Crowley is best known today as a founding father of modern occultism. His wide, hypnotic eyes peer at us from the cover of The Beatles' Sgt. Pepper's Lonely Hearts Club Band, and his influence can be found everywhere in popular culture.Crowley, also known as the Great Beast, has been the subject of several biographies, some painting him as a misunderstood genius, others as a manipulative charlatan. None of them have looked seriously at his career as an agent of British Intelligence.Using documents gleaned from British, American, French, and Italian archives, Secret Agent 666 sensationally reveals that Crowley played a major role in the sinking of the Lusitania, a plot to overthrow the government of Spain, the thwarting of Irish and Indian nationalist conspiracies, and the 1941 flight of Rudolf Hess.Author Richard B. Spence argues that Crowley--in his own unconventional way--was a patriotic Englishman who endured years of public vilification in part to mask his role as a secret agent.The verification of the Great Beast's participation in the twentieth century's most astounding government plots will likely blow the minds of history buff s and occult aficionados alike.Author Richard B. Spence can be seen on various documentaries on the History Channel and is a consultant for Washington, DC's International Spy Museum. He is also the author of Trust No One: The Secret World of Sidney Reilly (Feral House).
