Separable arrowhead microneedles.
Hypodermic needles cause pain and bleeding, produce biohazardous sharp waste and require trained personnel. To address these issues, we introduce separable arrowhead microneedles that rapidly and painlessly deliver drugs and vaccines to the skin. These needles are featured by micron-size sharp tips mounted on blunt shafts. Upon insertion in the skin, the sharp-tipped polymer arrowheads encapsul...
متن کاملArrowhead detection in biomedical images
Medical images in biomedical documents tend to be complex by nature and often contain several regions that are annotated using arrows. Arrowhead detection is a critical precursor to regionof-interest (ROI) labeling and image content analysis. To detect arrowheads, images are first binarized using fuzzy binarization technique to segment a set of candidates based on connected component principle....
متن کاملBroadcasting in the Arrowhead Torus
The \arrowhead torus" is a broadcast graph that we deene on the 6-valent grid as a Cayley graph. A 3-port wormhole broadcasting protocol is derived rst from construction, then improved by using edge-disjoint forests. A store-and-forward broadcasting protocol is derived afterwards, then improved by mixing pipelining and arc-disjoint spanning trees. Costs are given in constant and linear time and...
متن کاملEigenvectors of Arrowhead Matrices via the Adjugate
where r̄i is the complex conjugate of ri. Arrowhead matrices, named for their south-easterly pointing structure, occur in several physics problems including radiationless transitions in isolated molecules [1] and oscillators vibrationally coupled with a Fermi liquid [2]. While we were able to find two additional papers [3, 12] that use general arrowhead matrices for applications, the remaining m...
متن کاملMicroneedles-Mediated Transdermal Delivery
The objective of the present study was to evaluate the potential of hollow microneedles for enhancing the transdermal delivery of Bovine Serum Albumin (MW~66,000 Da)-Fluorescein Isothiocyanate (BSA-FITC) conjugate, a hydrophilic large molecular compound. Moreover, the effect of different formulations was evaluated. The series of binary mixtures composed of propylene glycol (PG) and pH 7.4 phosp...
