IET Radar, Sonar &Navigation, Volume 18, Issue 9, Page 1391-1408, September 2024.This model is an end‐to‐end ATR scheme, which has been experimentally validated on the MSTAR and OpenSARship datasets. Compared to other methods, the proposed method exhibits strong robustness in dealing with various imbalanced scenarios and significant generalisation capability across different datasets.

Chirotope Concept in Various Scenarios of Physics [PDF]
Rev.Mex.Fis. E51 (2005) 5-12, 2004 We argue that the chirotope concept of oriented matroid theory may be found in different scenarios of physics, including classical mechanics, quantum mechanics, gauge field theory, p-branes formalism, two time physics and Matrix theory. Our observations may motivate the interest of possible applications of matroid theory in physics.

On the Energy-Time Uncertainty Relations: A didactical note for undergraduate students [PDF]
Rev.Mex.Fis. E51 (2005) 23-30, 2005 The purpose of this brief note is that of discussing the meaning of the uncertainty relations involving energy and time in quantum mechanics by means of a reading of the classical works on the subject. This was written for undergraduate students attending to an introductory course in quantum mechanics.

Optical photometry and spectroscopy of the low-luminosity, broad-lined Ic supernova iPTF15dld [PDF]
, 2016 Core-collapse stripped-envelope supernova (SN) explosions reflect the diversity of physical parameters and evolutionary paths of their massive star progenitors. We have observed the type Ic SN iPTF15dld (z = 0.047), reported by the Palomar Transient Factory.

Nursing &Health Sciences, Volume 26, Issue 3, September 2024.Abstract Nursing preceptors play a crucial role in supporting and educating clinical students. Understanding the perceptions and needs of nurse preceptors is essential to enhance their role as preceptors and to improve their teaching practices. This study aimed to explore preceptorship in diverse settings and specific contexts.

Modelling the Type Ic SN 2004aw: a Moderately Energetic Explosion of a Massive C+O Star without a GRB [PDF]
, 2017 An analysis of the Type Ic supernova (SN) 2004aw is performed by means of models of the photospheric and nebular spectra and of the bolometric light curve. SN2004aw is shown not to be ``broad-lined'', contrary to previous claims, but rather a ``fast-lined'' SN Ic.

Small, Volume 20, Issue 31, August 1, 2024.A multifunctional additive (G@SiO2@FeHP) is fabricated by in situ immobilization of silica (SiO2) and iron phenylphosphinate (FeHP) onto the graphene (G) surface. The results demonstrate that the as‐designed G@SiO2@FeHP is a multifunctional, high‐efficiency additive, and 1.0 wt% of it can simultaneously improve the fire retardancy, mechanical ...

Veterinary Dermatology, Volume 35, Issue 4, Page 408-417, August 2024.Background – Supplementation of polyunsaturated fatty acids (PUFA) enables dose reduction of prednisolone and ciclosporin in canine atopic dermatitis (cAD). Objective – To determine if oral administration of PUFA can reduce the dose of oclacitinib for cAD. Conclusion – Oral supplementation of PUFA allowed dose reduction of oclacitinib and improved pVAS,
