Feeding the world's largest fish: highly variable whale shark residency patterns at a provisioning site in the Philippines.

Royal Society open science

Thomson JA, Araujo G, Labaja J, McCoy E, Murray R, Ponzo A.
PMID: 28989750
R Soc Open Sci. 2017 Sep 27;4(9):170394. doi: 10.1098/rsos.170394. eCollection 2017 Sep.

Provisioning wildlife for tourism is a controversial yet widespread practice. We analysed the residency patterns of juvenile whale sharks (

Polydopamine Films from the Forgotten Air/Water Interface.

The journal of physical chemistry letters

Ponzio F, Payamyar P, Schneider A, Winterhalter M, Bour J, Addiego F, Krafft MP, Hemmerle J, Ball V.
PMID: 26278460
J Phys Chem Lett. 2014 Oct 02;5(19):3436-40. doi: 10.1021/jz501842r. Epub 2014 Sep 24.

The formation of polydopamine under mild oxidation conditions from dopamine solutions with mechanical agitation leads to the formation of films that can functionalize all kinds of materials. In the absence of stirring of the solution, we report the formation...

Market reaction to a bid-ask spread change: a power-law relaxation dynamics.

Physical review. E, Statistical, nonlinear, and soft matter physics

Ponzi A, Lillo F, Mantegna RN.
PMID: 19658779
Phys Rev E Stat Nonlin Soft Matter Phys. 2009 Jul;80(1):016112. doi: 10.1103/PhysRevE.80.016112. Epub 2009 Jul 16.

We study the relaxation dynamics of the bid-ask spread and of the midprice after a sudden variation of the spread in a double auction financial market. We find that the spread decays as a power law to its normal...

Comparison of isolated sarcoplasmic reticulum from bovine and rabbit muscle.

Meat science

Kanda T, Pearson AM, Porzio MA, Cornforth DP.
PMID: 22054766
Meat Sci. 1977 Oct;1(4):253-62. doi: 10.1016/0309-1740(77)90020-1.

Comparison of the ultrastructure of purified bovine sarcoplasmic reticulum (SR) vesicles isolated from bovine sternomandibularis muscle before and following cold shortening indicates that the decreased Ca(2+)-accumulating ability and increased release of Ca(2+) in cold shortened muscle are not associated...

Scaling theorems for zero crossings.

IEEE transactions on pattern analysis and machine intelligence

Yuille AL, Poggio TA.
PMID: 21869319
IEEE Trans Pattern Anal Mach Intell. 1986 Jan;8(1):15-25. doi: 10.1109/tpami.1986.4767748.

We characterize some properties of the zero crossings of the Laplacian of signals¿in particular images¿filtered with linear filters, as a function of the scale of the filter (extending recent work by Witkin [16]). We prove that in any dimension...

On edge detection.

IEEE transactions on pattern analysis and machine intelligence

Torre V, Poggio TA.
PMID: 21869334
IEEE Trans Pattern Anal Mach Intell. 1986 Feb;8(2):147-63. doi: 10.1109/tpami.1986.4767769.

Edge detection is the process that attempts to characterize the intensity changes in the image in terms of the physical processes that have originated them. A critical, intermediate goal of edge detection is the detection and characterization of significant...

Squibb RJ, Sapunar M, Ponzi A, Richter R, Kivimäki A, Plekan O, Finetti P, Sisourat N, Zhaunerchyk V, Marchenko T, Journel L, Guillemin R, Cucini R, Coreno M, Grazioli C, Di Fraia M, Callegari C, Prince KC, Decleva P, Simon M, Eland JHD, Došlić N, Feifel R, Piancastelli MN.
PMID: 29302026
Nat Commun. 2018 Jan 04;9(1):63. doi: 10.1038/s41467-017-02478-0.

The first steps in photochemical processes, such as photosynthesis or animal vision, involve changes in electronic and geometric structure on extremely short time scales. Time-resolved photoelectron spectroscopy is a natural way to measure such changes, but has been hindered...

The salivary gland as a target for enhancing immunization response.

Tropical diseases, travel medicine and vaccines

Ponzio TA, Sanders JW.
PMID: 28883974
Trop Dis Travel Med Vaccines. 2017 Feb 17;3:4. doi: 10.1186/s40794-017-0047-z. eCollection 2017.

BACKGROUND: An organism's immune response to a vaccine is dependent on a number of factors, including the site of immunization. While muscle is the most common site for vaccine administration, other sites, including the salivary gland, are poised to...
