Al-Jabar, 2021 The higher-order thinking ability of students in Indonesia is still in the low category. This research aims to see the effect of the application of a problem-based learning model on higher-order mathematical thinking skills in terms of student's initial ...

A rewriting calculus for cyclic higher-order term graphs [PDF]
Mathematical Structures in Computer Science, 2005 The Rewriting Calculus (ρ-calculus, for short) was introduced at the end of the 1990s and fully integrates term-rewriting and λ-calculus. The rewrite rules, acting as elaborated abstractions, their application and the structured results obtained are first class objects of the calculus.

The Effects of Higher-Order Ionospheric Terms on GPS Tropospheric Delay and Gradient Estimates
Remote Sensing, 2018 Atmospheric delays, e.g., ionospheric delay and tropospheric delay, are the dominant error sources for the Global Navigation Satellite System (GNSS), especially for Precise Point Positioning (PPP).

Origin tracking for higher-order term rewriting systems [PDF]
, 1994 Origin Tracking is a technique which, in the framework of first-order term rewriting systems, establishes relations between each subterm t of a normal form and a set of subterms, the origins of t, in the initial term. Origin tracking is based on the notion of residuals.

Impact of higher‐order ionospheric terms on GPS estimates [PDF]
Geophysical Research Letters, 2005 Dual frequency GPS observables only allow the elimination of the 1st–order ionospheric term. Although higher–order ionospheric terms may cause a range bias of several centimeters, accounting for such effects is not yet a common strategy for GPS data analysis.

Multiparametric presentation of the crack-tip fields in the vicinity of longitudinal shear crack
Вестник Самарского университета: Естественнонаучная серияThe article is devoted to the study of the stress field at the tip of a longitudinal shear crack based on a multiparametric asymptotic representation of the stress field at the crack tip in a linearly elastic isotropic material.

Advances in Difference Equations, 2018 In this paper we consider the existence of positive solutions of nth-order Sturm–Liouville boundary value problems with fully nonlinear terms, in which the nonlinear term f involves all of the derivatives u′,…,u(n−1) $u',\ldots, u^{(n-1)}$ of the unknown

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Quantification and parametrization of non-linearity effects by higher-order sensitivity terms in scattered light differential optical absorption spectroscopy [PDF]
Atmospheric Measurement Techniques, 2016 We address the application of differential optical absorption spectroscopy (DOAS) of scattered light observations in the presence of strong absorbers (in particular ozone), for which the absorption optical depth is a non-linear function of the trace gas ...
