A study about the use of Musicomovigrams in musical education

Since the turn of the twenty-first century, information and communication technology (ICT) have definitely changed the way people express learning and interact with each other in the activities of science and arts, with a particular impact in musical education. In this article, the authors treat the concept of musicomovigrams, an interactive audiovisual resource, similar to video games that can work as software tools for the development of sound perception and musical structure. This concept is based on the previous concept of musicogram, created by the musical pedagogue Jos Wuytack along with his concept of Active Listening (Wuytack and Boal Palheiros, 2009). The authors consider an important element of learning the concepts of Musical Forms defined by the musical educator Keith Swanwick (Swanwick, 2003). This work presents the development of the musicomovigram concept, a videogame created through the free software eAdventure. We also intend to investigate how music teachers and students, who work and interact in musical education classrooms, are actually accepting and using ICT in their classes

Angular momentum effects in weak gravitational fields

It is shown that, contrary to what is normally expected, it is possible to have angular momentum effects on the geometry of space time at the laboratory scale, much bigger than the purely Newtonian effects. This is due to the fact that the ratio between the angular momentum of a body and its mass, expressed as a length, is easily greater than the mass itself, again expressed as a length.Comment: LATEX, 8 page

Measuring Performances of a White-Box Approach in the IoT Context

The internet of things (IoT) refers to all the smart objects that are connected to other objects, devices or servers and that are able to collect and share data, in order to "learn" and improve their functionalities. Smart objects suffer from lack of memory and computational power, since they are usually lightweight. Moreover, their security is weakened by the fact that smart objects can be placed in unprotected environments, where adversaries are able to play with the symmetric-key algorithm used and the device on which the cryptographic operations are executed. In this paper, we focus on a family of white-box symmetric ciphers substitution-permutation network (SPN)box, extending and improving our previous paper on the topic presented at WIDECOM2019. We highlight the importance of white-box cryptography in the IoT context, but also the need to have a fast black-box implementation (server-side) of the cipher. We show that, modifying an internal layer of SPNbox, we are able to increase the key length and to improve the performance of the implementation. We measure these improvements (a) on 32/64-bit architectures and (b) in the IoT context by encrypting/decrypting 10,000 payloads of lightweight messaging protocol Message Queuing Telemetry Transport (MQTT)

Efeito de formulações de dimetoato no controle de larvas de Anastrepha fraterculus (Wiedemann, 1830) (Diptera: Tephritidae) em laboratório.

O diometato é um dos inseticidas mais utilizados para o controle de Anastrepha fraterculus (Wied.) devido à eficiência, baixo custo e reduzida carência. Entretanto, é frequente o questionamento dos técnicos e produtores quanto à eficácia biológica do produto em função da formulação comercial. Neste trabalho foi avaliado o efeito das formulações comerciais de dimetoato disponiveis no mercado brasileiro para o controle de larvas de A. frateroulus em laboratório. O experimento foi realizado com insetos provenientes da criação mantida no Laboratório de Entomologia da Embrapa Uva e Vinho (temperatura de 23 ± 3°C, umidade relativa de 70 +/- 10% e fotoperíodo de 14 horas).Resumo

Robust thalamic nuclei segmentation method based on local diffusion magnetic resonance properties.

The thalamus is an essential relay station in the cortical-subcortical connections. It is characterized by a complex anatomical architecture composed of numerous small nuclei, which mediate the involvement of the thalamus in a wide range of neurological functions. We present a novel framework for segmenting the thalamic nuclei, which explores the orientation distribution functions (ODFs) from diffusion magnetic resonance images at 3 T. The differentiation of the complex intra-thalamic microstructure is improved by using the spherical harmonic (SH) representation of the ODFs, which provides full angular characterization of the diffusion process in each voxel. The clustering was performed using the k-means algorithm initialized in a data-driven manner. The method was tested on 35 healthy volunteers and our results show a robust, reproducible and accurate segmentation of the thalamus in seven nuclei groups. Six of them closely matched the anatomy and were labeled as anterior, ventral anterior, medio-dorsal, ventral latero-ventral, ventral latero-dorsal and pulvinar, while the seventh cluster included the centro-lateral and the latero-posterior nuclei. Results were evaluated both qualitatively, by comparing the segmented nuclei to the histological atlas of Morel, and quantitatively, by measuring the clusters' extent and the clusters' spatial distribution across subjects and hemispheres. We also showed the robustness of our approach across different sequences and scanners, as well as intra-subject reproducibility of the segmented clusters using additional two scan-rescan datasets. We also observed an overlap between the path of the main long-connection tracts passing through the thalamus and the spatial distribution of the nuclei identified with our clustering algorithm. Our approach, based on SH representations of the ODFs, outperforms the one based on angular differences between the principle diffusion directions, which is considered so far as state-of-the-art method. Our findings show an anatomically reliable segmentation of the main groups of thalamic nuclei that could be of potential use in many clinical applications

On the suitability of high vacuum electrospray deposition for the fabrication of molecular electronic devices

We present a series of three studies investigating the potential application of high vacuum electrospray deposition to construct molecular electronic devices. Through the use of time of flight secondary ion mass spectrometry we explore the use of this novel deposition technique to fabricating multilayer structures using materials that are compatible with the same solvents and films containing a mixture of molecules from orthogonal solvents. Using x-ray photoelectron spectroscopy we study the deposition of a polymer blend using electrospray and find evidence of preferential deposition of one of the components
