Spectral Clustering with Jensen-type kernels and their multi-point extensions

Motivated by multi-distribution divergences, which originate in information theory, we propose a notion of `multi-point' kernels, and study their applications. We study a class of kernels based on Jensen type divergences and show that these can be extended to measure similarity among multiple points. We study tensor flattening methods and develop a multi-point (kernel) spectral clustering (MSC) method. We further emphasize on a special case of the proposed kernels, which is a multi-point extension of the linear (dot-product) kernel and show the existence of cubic time tensor flattening algorithm in this case. Finally, we illustrate the usefulness of our contributions using standard data sets and image segmentation tasks.Comment: To appear in IEEE Computer Society Conference on Computer Vision and Pattern Recognitio

LGBTQ+ cancer: priority or lip service? A qualitative content analysis of LGBTQ+ considerations in U.S. state, jurisdiction, and tribal comprehensive cancer control plans

The National Comprehensive Cancer Control Program, a Centers for Disease Control and Prevention funded program, supports cancer coalitions across the United States (US) in efforts to prevent and control cancer including development of comprehensive cancer control (CCC) plans. CCC plans often focus health equity within their priorities, but it is unclear to what extent lesbian, gay, bisexual, transgender, queer/questioning, plus (LGBTQ+) populations are considered in CCC plans. We qualitatively examined to what extent LGBTQ+ populations were referenced in 64 U.S. state, jurisdiction, tribes, and tribal organization CCC plans. A total of 55% of CCC plans mentioned LGBTQ+ populations, however, only one in three CCC plans mentioned any kind of LGBTQ+ inequity or LGBTQ+ specific recommendations. Even fewer plans included mention of LGBTQ+ specific resources, organizations, or citations. At the same time almost three fourths of plans conflated sex and gender throughout their CCC plans. The findings of this study highlight the lack of prioritization of LGBTQ+ populations in CCC plans broadly while highlighting exemplar plans that can serve as a roadmap to more inclusive future CCC plans. Comprehensive cancer control plans can serve as a key policy and advocacy structure to promote a focus on LGBTQ+ cancer prevention and control

Effects of biofertilizer containing N-fixer, P and K solubilizers and AM fungi on maize growth: A greenhouse trial.

An in vitro study was undertaken to evaluate the compatibility of indigenous plant growth promoting rhizobacteria (PGPR) with commonly used inorganic and organic sources of fertilizers in tea plantations. The nitrogenous, phosphatic and potash fertilizers used for this study were urea, rock phosphate and muriate of potash, respectively. The organic sources of fertilizers neem cake, composted coir pith and vermicompost were also used. PGPRs such as nitrogen fixer; Azospirillum lipoferum, Phosphate Solubilizing Bacteria (PSB); Pseudomonas putida, Potassium Solubilizing Bacteria (KSB); Burkholderia cepacia and Pseudomonas putida were used for compatibility study. Results were indicated that PGPRs preferred the coir pith and they proved their higher colony establishment in the formulation except Azospirillum spp. that preferred vermicompost for their establishment. The optimum dose of neem cake powder

Coaxial Electrospun Cellulose-Core Fluoropolymer-Shell Fibrous Membrane from Recycled Cigarette Filter as Separator for High Performance Lithium-Ion Battery

This paper reports an eco-friendly approach for extracting cellulose acetate (CA) from waste cigarette filter to construct a cellulose-based membrane separator for a high-performance lithium-ion battery. A cellulose/poly(vinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) nanofiber membrane was prepared by coaxial electrospinning of a cellulose acetate core and PVDF-HFP shell, then hydrolyzed by LiOH. The cellulose-core/PVD-HFP-shell fibrous membrane shows good tensile strength (34.1 MPa), high porosity (66%), excellent thermal stability (to 200 °C), and super electrolyte compatibility (355% electrolyte uptake). It has a lower interfacial resistance (98.5 Ω) and higher ionic conductivity (6.16 mS cm-1) than those of commercial separators (280.0 Ω and 0.88 mS cm-1). In addition, the rate capability (138 mAh·g-1) and cycling performance (75.4% after 100 cycles) are also superior to those of the commercial separators, demonstrating the cellulose-core fibrous membrane to be a promising separator for a high-power and more secure lithium-ion battery
