Stack Sorting with Increasing and Decreasing Stacks [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2020
We introduce a sorting machine consisting of $k+1$ stacks in series: the first $k$ stacks can only contain elements in decreasing order from top to bottom, while the last one has the opposite restriction. This device generalizes the $\mathfrak{DI}$ machine introduced by Rebecca Smith, which studies the case $k=1$.

A Comparison Study of Roseolumiflavin Solvates: Structural and Energetic Perspective on Their Stability

open access: yesCrystals, 2023
Roseolumiflavin is a deep red microcrystalline derivative of isoalloxazine that exhibits a weak photophysical activity in the solid state. In aqueous as well as in acidic solution of formic or acetic acid, respectively, it tends to form solvates. Herein,

Dynamic Mechanical Strength Prediction of BFRC Based on Stacking Ensemble Learning and Genetic Algorithm Optimization

open access: yesBuildings, 2023
Split Hopkinson pressure bar (SHPB) tests are usually used to determine the dynamic mechanical strength of basalt-fiber-reinforced concrete (BFRC), but this test method is time-consuming and expensive.

Stacking-symmetry governed second harmonic generation in graphene trilayers [PDF]

open access: yes, 2018
Crystal symmetry plays a central role in governing a wide range of fundamental physical phenomena. One example is the nonlinear optical second harmonic generation (SHG), which requires inversion symmetry breaking. Here we report a unique stacking-induced

Adjectives in Heritage Spanish

open access: yesIsogloss, 2021
Ordering of predicative adjectives within the Noun Phrase varies cross linguistically in systematic ways (Cinque 2010). In Spanish adjectival ordering exhibits more flexibility than in English.

Predicting cervical cancer biopsy results using demographic and epidemiological parameters: a custom stacked ensemble machine learning approach

open access: yesCogent Engineering, 2022
The human papillomavirus (HPV) is responsible for most cervical cancer cases worldwide. This gynecological carcinoma causes many deaths, even though it can be treated by removing malignant tissues at a preliminary stage.

Interpreting uninterpretable predictors: kernel methods, Shtarkov solutions, and random forests

open access: yesStatistical Theory and Related Fields, 2022
Many of the best predictors for complex problems are typically regarded as hard to interpret physically. These include kernel methods, Shtarkov solutions, and random forests.
