Geometric reasoning in motion planning [PDF]

open access: yes, 1989
Automating the programming of assembly robots necessitates to develop methods for planning robot motions. In this paper we describe the geometric models and the reasoning techniques we have implemented as part of the SHARP system (SHARP is an automatic robot programming system currently under development at the LIFIA laboratory). We first present which

Preface to the special issue on geometric reasoning [PDF]

open access: yesAnnals of Mathematics and Artificial Intelligence, 2015
While much of geometry was done with pencil and paper in the past, we are now fortunate to have the computer as an additional tool that can help us investigate its formal representation and semantics, and apply appropriate reasoning procedures. This special issue, with a selection of six papers that combine both theory and practice, demonstrates that ...

Characterization of therapeutic antibodies targeting lymphatic and vascular resistance factor for the treatment of hypervascularized and highly metastatic cancers

open access: yesMolecular Oncology, EarlyView.
LVRF (lymphatic and vascular resistance factor) is a VEGFA splice variant upregulated in response to anti‐angiogenic therapy that fosters tumor adaptation through enhanced vascularization, lymphangiogenesis, and metastatic dissemination. Targeting LVRF with fully human neutralizing antibodies disrupts these processes and limits resistant tumor growth ...

Analysis of spatial reasoning ability in solving geometric transformation problems

open access: yesJurnal Math Educator Nusantara: Wahana Publikasi Karya Tulis Ilmiah di Bidang Pendidikan Matematika
Spatial reasoning ability significantly affects mathematics learning in the area of geometric transformations. However, students’ spatial reasoning ability is still underdeveloped. This study focused on analyzing students’ spatial reasoning ability while

Reasoning, Representing, and Generalizing in Geometric Proof Problems among 8th Grade Talented Students

open access: yesMathematics, 2022
Proof, a key topic in advanced mathematics, also forms an essential part of the formal learning experience at all levels of education. The reason is that the argumentation involved calls for pondering ideas in depth, organizing knowledge, and comparing ...

Recent Advances in Real Geometric Reasoning [PDF]

open access: yes, 2015
In the 1930s Tarski showed that real quantifier elimination was possible, and in 1975 Collins gave a remotely practicable method, albeit with doubly-exponential complexity, which was later shown to be inherent. We discuss some of the recent major advances in Collins method: such as an alternative approach based on passing via the complexes, and ...

An outer membrane vesicle‐associated two‐track model for enterotoxigenic Bacteroides fragilis oncogenesis

open access: yesMolecular Oncology, EarlyView.
Enterotoxigenic Bacteroides fragilis is a gut bacterium linked to bowel cancer. We propose that its toxin acts along two routes: at the cell surface, cutting the adhesion protein E‐cadherin and triggering inflammation; and inside the cell, delivered by bacterial vesicles, switching on NOD1 and cancer stem cell programs.

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

open access: yesFEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly

Pre-service Elementary Mathematics Teachers’ Views About Geometric Construction

open access: yesKuramsal Eğitimbilim Dergisi, 2014
Geometrical reasoning involves three kinds of cognitive process: visualization process, construction process and reasoning process. Although many studies about the visualization and reasoning process in the learning geometry found in the literature ...

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

open access: yesFEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.
