On the Role of the Vocal Teacher’s Capability of Singing Played at Vocal Music Teaching
Vocal music is an art of seeing, hearing and sensation and vocal music teaching is not as audio visual as that of the other types. Students learn only through the teacher’s correct demonstration singing and teaching language to comprehend and experience conscientiously. In my years of teaching practice, I realized deeply how important the teaching quality is for students. This paper expounds the roles and importance of the vocal teacher reaching a certain level in singing capability in terms of the distinctiveness of vocal music teaching. Key words: Improve, the capability of singing, vocal music teaching, role Résumé: La musique vocale est un art de perception audio-visuelle. L’enseignement-apprentissage(E/A) de la musique vocale n’est pas aussi direct que celui des autres disciplines. Les élèves n’apprennent qu’en percevant par l’intelligence à travers la démonstration correcte du professeur et son langage d’enseignement. Durant l’enseignement de longue date, l’auteur éprouve profondément l’importance de la qualité d’enseignement de la musique vocale. Commençant par les particularités de l’E/A de la musique vocale, le présent article expose le rôle et l’importance de la capacité de chanter des professeurs dans l’E/A de la musique vocale.

Majorana Fermion Induced Non-local Current Correlations in Spin-orbit Coupled Superconducting Wires
Recent observation of zero bias conductance peaks in semiconductor
wire/superconductor heterostructures has generated great interest, and there is
a hot debate on whether the observation is associated with Majorana fermions
(MFs). Here we study the local and crossed Andreev reflections in a junction of
two normal leads and a sandwiched superconductor-semiconductor wire with two
spatially separated but strongly coupled MF end states. The conductance and
Fano factors of such a device are sharply different from the topologically
trivial case even in the presence of disorder, and can hence be used to
identify MFs unambiguously.Comment: 7+ pages, 10 figure
Mandarin speech perception in combined electric and acoustic stimulation.
For deaf individuals with residual low-frequency acoustic hearing, combined use of a cochlear implant (CI) and hearing aid (HA) typically provides better speech understanding than with either device alone. Because of coarse spectral resolution, CIs do not provide fundamental frequency (F0) information that contributes to understanding of tonal languages such as Mandarin Chinese. The HA can provide good representation of F0 and, depending on the range of aided acoustic hearing, first and second formant (F1 and F2) information. In this study, Mandarin tone, vowel, and consonant recognition in quiet and noise was measured in 12 adult Mandarin-speaking bimodal listeners with the CI-only and with the CI+HA. Tone recognition was significantly better with the CI+HA in noise, but not in quiet. Vowel recognition was significantly better with the CI+HA in quiet, but not in noise. There was no significant difference in consonant recognition between the CI-only and the CI+HA in quiet or in noise. There was a wide range in bimodal benefit, with improvements often greater than 20 percentage points in some tests and conditions. The bimodal benefit was compared to CI subjects' HA-aided pure-tone average (PTA) thresholds between 250 and 2000 Hz; subjects were divided into two groups: "better" PTA (<50 dB HL) or "poorer" PTA (>50 dB HL). The bimodal benefit differed significantly between groups only for consonant recognition. The bimodal benefit for tone recognition in quiet was significantly correlated with CI experience, suggesting that bimodal CI users learn to better combine low-frequency spectro-temporal information from acoustic hearing with temporal envelope information from electric hearing. Given the small number of subjects in this study (n = 12), further research with Chinese bimodal listeners may provide more information regarding the contribution of acoustic and electric hearing to tonal language perception
Revision in Continuous Space: Unsupervised Text Style Transfer without Adversarial Learning
Typical methods for unsupervised text style transfer often rely on two key
ingredients: 1) seeking the explicit disentanglement of the content and the
attributes, and 2) troublesome adversarial learning. In this paper, we show
that neither of these components is indispensable. We propose a new framework
that utilizes the gradients to revise the sentence in a continuous space during
inference to achieve text style transfer. Our method consists of three key
components: a variational auto-encoder (VAE), some attribute predictors (one
for each attribute), and a content predictor. The VAE and the two types of
predictors enable us to perform gradient-based optimization in the continuous
space, which is mapped from sentences in a discrete space, to find the
representation of a target sentence with the desired attributes and preserved
content. Moreover, the proposed method naturally has the ability to
simultaneously manipulate multiple fine-grained attributes, such as sentence
length and the presence of specific words, when performing text style transfer
tasks. Compared with previous adversarial learning based methods, the proposed
method is more interpretable, controllable and easier to train. Extensive
experimental studies on three popular text style transfer tasks show that the
proposed method significantly outperforms five state-of-the-art methods.Comment: Association for the Advancement of Artificial Intelligence. AAAI 202
Entropic destruction of heavy quarkonium from a deformed model
In this paper, we study the destruction of heavy quarkonium due to the
entropic force in a deformed model. The effects of the deformation
parameter on the inter-distance and the entropic force are investigated. The
influence of the deformation parameter on the quarkonium dissociation is
analyzed. It is shown that the inter-distance increases in the presence of the
deformation parameter. In addition, the deformation parameter has the effect of
decreasing the entropic force. This results imply that the quarkonium
dissociates harder in a deformed AdS background than that in an usual AdS
background, in agreement with earlier findings.Comment: 6 pages, 2 figures. Accepted by Advances in High Energy Physic
