The wreckfish individual transferable quota (ITQ) program started in 1992 and is the oldest finfish ITQ program in the United States. Initially, the program appeared to be a success, bringing order to the previous years’ derbies. Ex-vessel prices rose, harvest stabilized, and there was an orderly shrinking of the fleet to an economically appropriate size. The subsequent history of the fishery i...
Iterative Quantization (ITQ) is one of the most successful hashing based nearest-neighbor search methods for large-scale information retrieval in the past a few years due to its simplicity and superior performance. However, the performance of this algorithm degrades significantly when dealing with noisy data. Additionally, it can barely facilitate a wide range of applications as the distortion ...
The synthesis of crystalline microporous materials containing large pores is in high demand by industry, especially for the use of these materials as catalysts in chemical processes involving bulky molecules. An extra-large-pore silicoaluminophosphate with 16-ring openings, ITQ-51, has been synthesized by the use of bulky aromatic proton sponges as organic structure-directing agents. Proton spo...
Market-based approaches to environmental regulation (such as tradable permits or transferable quotas) are frequently offered as innovative solutions to many environmental problems. Globally, one of the most well-established forms of this approach is individual transferable quotas (or ITQs) in fisheries management. Within the natural resource management community, there is considerable debate ov...
The aim of this work is to exploit the pyrolysis characteristics microalgae Botryococcus braunii (BB) with a medium pore framework zeolite (MCM-22) and its delaminated counterpart higher external surface area (ITQ-2) using pyrolysis-gas-chromatography-mass-spectrometry (Py-GC/MS) fixed-bed reactor. study evaluates effect synthesized zeolites that possess different size, shape acidity on promoti...
INTRODUCTION Using the Indian and rest of world (ROW) injection technique questionnaire (ITQ) data, we address key insulin injection complications. METHODS In 2015 we conducted an ITQ survey throughout India involving 1011 patients. Indian values were compared with those from 41 other countries participating in the ITQ, known here as ROW. RESULTS More than a quarter of Indian insulin users ...
ITQ-69 has been synthesized, characterized, and its application as selective adsorbent for light olefins/paraffins tested.
This work fulfills sublinear time Nearest Neighbor Search (NNS) in massivescale document collections. The primary contribution is to propose a two-stage unsupervised hashing framework which harmoniously integrates two state-of-theart hashing algorithms Locality Sensitive Hashing (LSH) and Iterative Quantization (ITQ). LSH accounts for neighbor candidate pruning, while ITQ provides an efficient ...
The new synthetic form of microporous crystalline silica, denoted as ITQ-12, shows a high potential for the separation of propane and propene from its mixtures.
