One-dimensional compression of a crushable sand in dry and wet conditions [PDF]

, 2015
This paper presents the results of a series of dry and wet one-dimenional compression tests on a calcareous sand from the Persian Gulf. Calcareous grains crush more easily compared to silica grains, a fact that is mainly attributed to their angular shape

Insights into the sand fly saliva: Blood-feeding and immune interactions between sand flies, hosts, and Leishmania

PLoS Neglected Tropical Diseases, 2017
Background Leishmaniases are parasitic diseases present worldwide that are transmitted to the vertebrate host by the bite of an infected sand fly during a blood feeding.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Radio Frequency Properties of a 3D Printed Klystron Circuit

Instruments
The manufacturing of active RF devices like klystrons is dominated by expensive and time-consuming cycles of machining and brazing. In this article, we characterize the RF properties of X-band klystron cavities and an integrated circuit manufactured with

Risk factors of chronic pain after inguinal hernia repair: a systematic review

Innovative Surgical Sciences, 2017
Chronic postoperative inguinal pain (CPIP) is the most common complication after inguinal hernia operation. Eighteen percent (range, 0.7%–75%) of patients suffered from CPIP after open inguinal hernia repair and 6% (range, 1%–16%) reported CPIP after ...

A hybrid neural architecture: Online attosecond x-ray characterization [PDF]

APL Machine Learning
The emergence of high-repetition-rate x-ray free-electron lasers (XFELs), such as SLAC’s LCLS-II, serves as our canonical example for autonomous controls that necessitate high-throughput diagnostics paired with streaming computational pipelines capable ...

Modelling Washboard Road: from experimental measurements to linear stability analysis

, 2013
When submitted to the repeated passages of vehicles unpaved roads made of sand or gravel can develop a ripply pattern known as washboard or corrugated road. We propose a stability analysis based on experimental measurements of the force acting on a blade

Laboratory colonization and mass rearing of phlebotomine sand flies (Diptera, Psychodidae)

Parasite, 2017
Laboratory colonies of phlebotomine sand flies are necessary for experimental study of their biology, behaviour and mutual relations with disease agents and for testing new methods of vector control.
