Structural Heterogeneity Shapes Segmentation of Megathrust Earthquakes and Volcanism in Central America

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The mechanisms underlying the patchy distribution of forearc megathrust earthquakes and arc volcanoes in subduction zones remain poorly understood. Here we present a high‐resolution seismic tomographic model of the Central American subduction zone, derived from a joint inversion of local body‐wave and teleseismic Rayleigh‐wave data.

Simplified placement and management of cutting setons in the treatment of transsphincteric anal fistula: technical note [PDF]

open access: yesInternational Journal of Colorectal Disease, 2004
We report one safe and standardized technique of seton placement and management.A simplified way to manage cutting setons helps to minimize manipulation and may reduce pain. In most patients our technique can be used with no additional anesthesia and in an outpatient setting.

Long-term outcomes of (Gore) fistula plug versus ligation of intersphincteric fistula tract for anal fistula

open access: yesJournal of Coloproctology, 2018
Background: The surgical treatment of anal fistula is complex due to the possibility of fecal incontinence. Fistulotomy and cutting Setons have the same incidence of fecal incontinence depending on the complexity of the fistula.

Decadal Bowhead Whale Baleen Stable Isotope and Hormone Chronologies (1985–2010) Provide Insight Into Arctic Ecosystem Change

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Long‐term chronologies constructed from individual bowhead baleen plates reveal stable isotope declines consistent with regional Arctic food web or productivity changes superimposed on global anthropogenic C and N inputs, while relatively stable hormone concentrations over the same period provide no evidence of a concomitant increase in physiological ...

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

open access: yesWildlife Monographs, Volume 226, Issue 1, September 2026.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Combined Partial Fistulotomy and Cutting Seton Procedure for Complex Anal Fistula

open access: yesJournal of Current and Advance Medical Research, 2020
Background: Fistula in ano of complex variety has been a common surgical problem. Varieties of surgical procedures are encountered for management of this disease but recurrence is a notorious complication of this disease. Objective: The purpose of the present study was to assess outcomes of complex fistula in ano after fistulotomy with seton procedure.

Anal fistula plug versus surgeon’s preference for surgery for trans-sphincteric anal fistula: the FIAT RCT

open access: yesHealth Technology Assessment, 2019
Background: The aim of fistula surgery is to eradicate the disease while preserving anal sphincter function. The efficacy of the Surgisis® anal fistula plug (Cook Medical, Bloomington, IN, USA) in the treatment of trans-sphincteric fistula-in-ano has ...

Multi‐Stage Evolution of Subducted Oceanic Mantle: The Marlborough Ultramafic Suite (New England Orogen, Australia)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Oceanic lithosphere is continuously destroyed by subduction, challenging our ability to develop tectonic reconstructions. One way to tackle this problem is to examine relics of once‐consumed oceanic domains preserved along convergent margins. In the New England Orogen (eastern Australia), disrupted exposures of ultramafic rocks loosely define ...

Thermal and Structural Signatures Associated With Subducted Seamounts in Hyuga‐nada and Off Cape Muroto, Southwest Japan

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We present heat flow estimates beneath the forearc slopes off Hyuga‐nada and Cape Muroto in the Nankai Trough, where the Philippine Sea plate subducts beneath the southwestern Japan. Using seismic reflection data, we identified Bottom Simulating Reflectors and derived heat flow ranging from 20 to >140 mW/m2.
