Abstract INTRODUCTION Among the strategic lines of EECTI document (Spanish Strategy for Science, Technology and Innovation 2021-2027) related with health, there is a subline that refers to: New diagnostic therapeutic techniques. The objective to analyze patents medical-surgical devices in field Minimally Invasive Surgery (MIS) Spain. MATERIAL AND METHODS Data surgical MIS Laparoscopic are colle...

Behavioural flexibility is considered a key factor in the ability to adapt to changing environments. A traditional way of characterizing behavioural flexibility is to determine whether individuals invent solutions to novel problems, termed innovativeness. Great-tailed grackles are behaviourally flexible in that they can change their preferences when a task changes using existing behaviours; how...

Invention as Preparation for Learning (IPL) is a teaching strategy in which students attempt to develop novel solutions prior to receiving instruction (Schwartz & Taylor, 2004). This method was previously shown to prepare students to learn independently from future learning opportunities that build upon the materials learned in class. We began unpacking the IPL process by identifying its compon...

We use the polynomial ring C[x1,1, . . . , xn,n] to modify the Kazhdan-Lusztig construction of irreducible Snmodules. This modified construction produces exactly the same matrices as the original construction in [Invent. Math 53 (1979)], but does not employ the Kazhdan-Lusztig preorders. We also show that our modules are related by unitriangular transition matrices to those constructed by Claus...

LetG be a reductive group over an algebraically closed field of characteristic p, and let u ∈ G be a unipotent element of order p. Suppose that p is a good prime for G. We show in this paper that there is a homomorphism φ : SL2/k → G whose image contains u. This result was first obtained by D. Testerman (J. Algebra, 1995) using case considerations for each type of simple group (and using, in so...

Abstract This study on technology education in preschool aims to explore how activities are enacted and what knowledge, related the five dimensions of nature technology, is made possible for children learn when intersubjectivity established interaction between participants. The empirical data encompass three video-documented activities, involving one teacher. Drawing by DiGironimo, participants...

We inconvexity) of star-shaped toric domains in [Formula: see text]. In particular, based on the criterion from Chaidez–Edtmair [Invent. Math. 229(1) (2022) 243–301] via Ruelle invariant and systolic ratio boundary domains, we provide elementary operations that can kill symplectic convexity. These only result small perturbations terms domains’ volume. Moreover, one is a systematic way to produc...

This paper starts out with the discussion of two metaphysical assumptions on which IS research can be based, namely positivism and constructionism. While positivism believes in the existence of an objective and measurable world, constructionism holds that the world is a social construct. Depending on the metaphysical basis, the IS researcher chooses a methodological approach. Traditionally, pos...

Depending on the subpopulation, obstructive sleep apnea (OSA) can affect more than 75% of surgical patients. An increasing body of evidence supports the association between OSA  and perioperative complications, but some data indicate important perioperative outcomes do not differ between patients with and without OSA. In this review we will provide an overview of the pathophysiology of sleep ap...
