The legendary overland silk road was not the only way to reach Asia for ancient travelers from the Mediterranean. During the Roman Empire’s heyday, equally important maritime routes reached from the ...Egyptian Red Sea across the Indian Ocean. The ancient city of Berenike, located approximately 500 miles south of today’s Suez Canal, was a significant port among these conduits. In this book, Steven E. Sidebotham, the archaeologist who excavated Berenike, uncovers the role the city played in the regional, local, and “global” economies during the eight centuries of its existence. Sidebotham analyzes many of the artifacts, botanical and faunal remains, and hundreds of the texts he and his team found in excavations, providing a profoundly intimate glimpse of the people who lived, worked, and died in this emporium between the classical Mediterranean world and Asia.
This paper is concerned about sparse, continuous frequency estimation in line spectral estimation, and focused on developing gridless sparse methods which overcome grid mismatches and correspond to ...limiting scenarios of existing grid-based approaches, e.g., ℓ 1 optimization and SPICE, with an infinitely dense grid. We generalize AST (atomic-norm soft thresholding) to the case of nonconsecutively sampled data (incomplete data) inspired by recent atomic norm based techniques. We present a gridless version of SPICE (gridless SPICE, or GLS), which is applicable to both complete and incomplete data without the knowledge of noise level. We further prove the equivalence between GLS and atomic norm-based techniques under different assumptions of noise. Moreover, we extend GLS to a systematic framework consisting of model order selection and robust frequency estimation, and present feasible algorithms for AST and GLS. Numerical simulations are provided to validate our theoretical analysis and demonstrate performance of our methods compared to existing ones.
Gary Paul Nabhan takes the reader on a vivid and far-ranging journey across time and space in this fascinating look at the relationship between the spice trade and culinary imperialism. Drawing on ...his own family’s history as spice traders, as well as travel narratives, historical accounts, and his expertise as an ethnobotanist, Nabhan describes the critical roles that Semitic peoples and desert floras had in setting the stage for globalized spice trade. Traveling along four prominent trade routes—the Silk Road, the Frankincense Trail, the Spice Route, and the Camino Real (for chiles and chocolate)—Nabhan follows the caravans of itinerant spice merchants from the frankincense-gathering grounds and ancient harbors of the Arabian Peninsula to the port of Zayton on the China Sea to Santa Fe in the southwest United States. His stories, recipes, and linguistic analyses of cultural diffusion routes reveal the extent to which aromatics such as cumin, cinnamon, saffron, and peppers became adopted worldwide as signature ingredients of diverse cuisines. Cumin, Camels, and Caravans demonstrates that two particular desert cultures often depicted in constant conflict—Arabs and Jews—have spent much of their history collaborating in the spice trade and suggests how a more virtuous multicultural globalized society may be achieved in the future.
Since its inception over two millennia ago, the spice trade has connected and transformed the environments, politics, cultures, and cuisines of vastly different societies around the world. The ...‘magical’ qualities of spices mean they offer more than a mere food flavoring, often evoking memories of childhood events or specific festivals. Although spices are frequently found in our kitchen cupboards, how they get there has something of a mythical allure. In this ethnographically rich and insightful study, the authors embark on a journey of demystification that starts in the Sino-Vietnamese uplands with three spices – star anise, black cardamom, and cassia (cinnamon) – and ends on dining tables across the globe. This book foregrounds the experiences of ethnic minority farmers cultivating these spices, highlighting nuanced entanglements among livelihoods, environment, ethnic identity, and external pressures, as well as other factors at play. It then investigates the complex commodity chains that move and transform these spices from upland smallholdings and forests in this frontier to global markets, mapping the flows of spices, identifying the numerous actors involved, and teasing out critical power imbalances. Finally, it focuses on value-creation and the commoditization of these spices across a spectrum of people and places. This rich and carefully integrated volume offers new insights into upland frontier livelihoods and the ongoing implications of the contemporary agrarian transition. Moreover, it bridges the gap in our knowledge regarding how these specific spices, cultivated for centuries in the mountainous Sino-Vietnamese uplands, become everyday ingredients in Global North food, cosmetics, and medicines. Links to online resources, including story maps, provide further insights and visual highlights.
Forensic investigation is very crucial for identifying quality and safety issues related to food and its product. GC- MS has been used extensively in food analysis, and in the present study, it was ...used to identify the active constituents of some household spices as well as to detect the adulterants and contaminants which might be present in the samples. Spices used in the present study are black pepper, cumin, fennel, coriander and turmeric. The spice extracts were found to be useful in authenticating the spices by identifying various active constituents of the spices, like piperine, caryophyllene and 3- carene in black pepper; cuminaldehyde and 1, 3- methadien- 7- al in cumin; anethole and fenchone in fennel; linalool, and geranyl vinyl ether in coriander and turmerone and zingiberene in turmeric. The adulterants detected qualitatively were plant- based adulterants. GC- MS is proved to be an effective tool in detecting plant- based adulterants, microbial contaminants, and agro chemical residues as well as industrial and manufacturing waste.
The generalized sparse iterative covariance-based estimation (<inline-formula> <tex-math notation="LaTeX">q </tex-math></inline-formula>-SPICE) algorithm was recently introduced for scanning radar ...applications, resulting in substantial improvements in the angular resolution and quality of the processed images. Regrettably, the computational complexity and storage cost are high and quickly increase with growing data size, limiting the applicability of the estimator. In this letter, we strive to alleviate this problem, deriving a beam-updating <inline-formula> <tex-math notation="LaTeX">q </tex-math></inline-formula>-SPICE algorithm, allowing for efficiently updating of the sparse reconstruction result for each online radar measurement along the scanned beam. The resulting method is a regularized extension of the current online <inline-formula> <tex-math notation="LaTeX">q </tex-math></inline-formula>-SPICE implementation, which not only offers constant computational and storage cost, independent of the data size, but also provides enhanced robustness over the current online <inline-formula> <tex-math notation="LaTeX">q </tex-math></inline-formula>-SPICE. Our experimental assessment, conducted using both simulated and real data, demonstrates the advantage of the beam-updating <inline-formula> <tex-math notation="LaTeX">q </tex-math></inline-formula>-SPICE method in the task of sparse reconstruction for scanning radar.
