Spinodal decomposition in the inverse cascade of two-dimensional, binary-fluid turbulence
No full textWe study spinodal decomposition in the inverse-cascade regime of two dimensional turbulence in symmetric, binary fluid mixtures. We show that turbulence leads to break up of domains whose size, in the inverse cascade regime, is proportional to the Hinze scale. Even more strikingly, we show that the inverse cascade of energy is blocked by the formation of domains
New genera, a new species, and a key to the genera of Ashieldophyinae (Acari, Eriophyoidea) from India
No full textTwo new genera, Brevishieldophyes Chakrabarti & Pandit, gen. n. and Mesoshieldophyes Chakrabarti & Pandit, gen. n., and a new species Mesoshieldophyes varecae Chakrabarti & Pandit, sp. n. are described. These mites are leaf vagrants. The morphological characters of the afore-mentioned genera and those of Ashieldophyes Mohanasundaram are compared. A key for separating the genera within the subfamily Ashieldophyinae is provided. The diagnostic characters of the subfamily Ashieldophyinae are also revised
Multifractal Droplet Dynamics in Two-Dimensional, binary-fluid turbulence
No full textWe present the most extensive direct numerical simulations, attempted so far, of statistically steady, homogeneous, isotropic turbulence in two-dimensional, binary-fluid mixtures with air-drag-induced friction. We model this mixture by using the Cahn-Hilliard-Navier-Stokes equations and choose parameters, e.g., the surface tension, such that we have a droplet of the minority phase moving inside a turbulent background of the majority phase. Our study reveals that a single droplet, whose mean radius lies in the inertial range of scales, (a) enhances the the forward-cascade part of the energy spectrum of two-dimensional turbulence and (b) stretches the tails of the PDF of the Okubo-Weiss parameter . We show that the dynamics of the droplet is affected significantly by the turbulence in the fluid. In particular, the PDFs of the components of the acceleration shows wide, non-Guassian tails. We characterize the time dependence of the deformation of the droplet and show that it exhibits multifractality

Thananchai Pandit Chadok: The Cultural Transmission Of A Jataka Tale
No full textThe Thananchai Pandit Chadok (TPC) is a long Buddhist birth story existing in Pali and Thai versions that circulated in palm leaf texts in central Thailand, perhaps as early as the 14th century. After a discussion of the nature and diversity of the Buddhist jātakas and their place in Thai art and literature, a summary and partial translation of the Thai version of TPC is presented. Its bodhisatta hero is a royal pandit who answers numerous riddles posed by the king, in this way exemplifying the perfection of wisdom. His answers, drawing on a variety of sources of Buddhist doctrine, including other jātakas and nīti aphorisms, constitute a series of discourses on moral topics, including the nature of the ideal Buddhist polity. As a result the tale has a compartmentalized structure and, given the premodern context, may have served as a kind of practical compendium or handbook for moral teaching or religious oratory. The thesis also examines the relationship of TPC to two better-known texts with a similar protagonist, the Mahosot jātaka (MJ) in the Pali Canon, and the Thai trickster legend Sri Thanonchai (ST). MJ clearly served as a model for the authors of TPC, who expanded certain sections (on the sage's marriage) and added others (his conversion of a yakkha.) By contrast, ST is an irreverent antitext, its hero an ambitious and amoral royal servant who subverts authority through puns and taking orders literally, all for personal gain. The story is well-known in Thailand, and in the modern Thai public sphere, where Buddhist moralizing plays a normative role, it has taken on added political meanings. Juxtaposition of the two texts can help us understand the interplay between didactic and satirical modes which is a salient feature of contemporary Thai public discourse

No full textNovel PET Imaging Techniques in the Management of Hematologic Malignancies
No full textHematology is probably the most relevant application field of PET since the widespread adoption of PET in the 1990s. Currently, the use of PET is indispensable in the natural history of almost all onco-hematologic diseases. With the advent of innovative therapies, such as CAR-T, the use of PET has gained further clinical diagnostic value. Significant innovations are also seen in the therapeutic and theranostic fields, and greater developments are anticipated in the future. Ultimately, the clinical applications of PET in onco-hematology likely represent the largest portion of the daily workload in most PET centers, and clinical hematologists have long relied on these molecular imaging techniques.
In the current issue, we have asked leading international experts in onco-hematology imaging and therapy to contribute their insights on the state-of-the-art applications of PET and therapeutic techniques in major hematologic diseases and to provide perspectives on potential future diagnostic and therapeutic applications in this field. Despite the necessarily limited space, we have endeavored to cover all relevant topics. Contributions have come from top experts in both established application fields, which constitute the daily practice, such as in the article “[18F]FDG PET Imaging for Therapy Assessment in Hodgkin and Non-Hodgkin Lymphomas" by the group led by Prof Roland Hustinx, and in new diagnostic possibilities in the article "New PET Tracers for Lymphoma." Therapeutic applications also have an important focus: the past and future of therapeutic applications in lymphomas have been brightly reported by a leading expert, such as Prof Elba Etchebehere, and collaborators. We have given ample space to current and future diagnostic applications in Multiple Myeloma, including a comparison of PET imaging with whole-body MR imaging. This issue would not be complete without mentioning the contribution of new PET machines with long axial fields of view, with an interesting article by Prof Nardo from the University of California, Davis, or the applications of PET in Chimeric Antigen Receptor T-Cell Trafficking, radiomics, or new quantitative PET methods in onco-hematology.
In conclusion, the use of PET and radioligand therapies in onco-hematology constitutes the present of our daily activities, but innovations in new theranostic radiopharmaceuticals and technological advancements ensure an increasingly bright future and an ever-greater significance of molecular imaging in onco-hematology.
We want to thank all the authors and collaborators for their spontaneous, free, and enthusiastic contributions to this project, which will undoubtedly be a valuable resource for both clinicians and imaging experts
Iron-Catalyzed C−H Alkylation/Ring Opening with Vinylbenzofurans Enabled by Triazoles
No full textWe report an unprecedented iron-catalyzed C−H annulation using readily available 2-vinylbenzofurans as the reaction pattern. The redox-neutral strategy, based on cheap, non-toxic, and earth-abundant iron catalysts, exploits triazole assistance to promote a cascade C−H alkylation, benzofuran ring-opening and insertion into a Fe−N bond, to form highly functionalized isoquinolones. Detailed mechanistic studies supported by DFT calculations fully disclosed the manifold of the iron catalysis
