We present limiting shape results for a non-abelian variant of the abelian sandpile growth model (ASGM), some of which have no parallel in the ASGM. One of our limiting shapes is an octagon. In our model, mass spreads from the origin by the toppling rule in Zhang’s sandpile model. Previously, several limiting shape results have been obtained for the ASGM using abelianness and monotonicity as ma...

Flexural toppling is typically observed in anti-dip bedding rock slopes with a set of steeply dipping parallel joints against the slope face. This failure occurs due to bending strata, similar cantilever beams. However, exact surface usually unknown, which leads an assumption regarding location and shape that must be made theoretical analysis. serves as basis for stability analysis but may lead...

The slide attack is applicable to ciphers that can be represented as an iterative application of the same keyed permutation. The slide attack leverages simple attacks on the keyed permutation to more complicated (and time consuming) attacks on the entire cipher. In this paper we extend the slide attack by examining the cycle structures of the entire cipher and of the underlying keyed permutatio...

OBJECTIVE To describe our experience with cervical slide tracheoplasty (CST) in managing complex laryngotracheal disorders. DESIGN Retrospective analysis. SETTING Quaternary care pediatric institution. PATIENTS The study included 29 patients who underwent CST without cardiopulmonary bypass at our institution from January 2003 to January 2011. MAIN OUTCOME MEASURE Surgery-specific and ov...

We present limiting shape results for a non-abelian variant of the abelian sandpile growth model (ASGM), some of which have no analog in the ASGM. One of our limiting shapes is an octagon. In our model, mass spreads from the origin by the toppling rule in Zhang’s sandpile model. Previously, several limiting shape results have been obtained for the ASGM using abelianness and monotonicity as main...

This work tackles the automatic fine-grained slide quality assessment problem for digitized direct smears test using the Gram staining protocol. Automatic quality assessment can provide useful information for the pathologists and the whole digital pathology workflow. For instance, if the system found a slide to have a low staining quality, it could send a request to the automatic slide preparat...
