Singing Voice Detection: A Survey

Singing voice detection or vocal detection is a classification task that determines whether there is a singing voice in a given audio segment. This process is a crucial preprocessing step that can be used to improve the performance of other tasks such as automatic lyrics alignment, singing melody transcription, singing voice separation, vocal melody extraction, and many more. This paper presents a survey on the techniques of singing voice detection with a deep focus on state-of-the-art algorithms such as convolutional LSTM and GRU-RNN. It illustrates a comparison between existing methods for singing voice detection, mainly based on the Jamendo and RWC datasets. Long-term recurrent convolutional networks have reached impressive results on public datasets. The main goal of the present paper is to investigate both classical and state-of-the-art approaches to singing voice detection.

Portraying Rare and Misdiagnosed Diseases in Movies

This chapter examines the portrayal of rare and misdiagnosed diseases in 9 movies from 1980 to 2018. The analysis embodies the representation of rare diseases and the suggested audiovisual strategies to comprehend the message conveyed. Most of the movies introduced the disease by highlighting its symptoms. The binomial culture of cure and care often emerges, as well as the patient's desire for the mundane pleasures in life and over dependence in a health system. The high hopes in research advances and lack of information are majorly covered in the caregivers' attempts to seek tests and drug trials and their mediator's role in patient-physician interactions. The audiovisual strategies adopted vary between the accelerated montage to communicate the contrast between the frenetic side of everyday life and the patient's process of coping with the disease, deep focus from patients to parents, and close-ups to show the individual's reactions and perspectives.

SEISMICITY of the AMUR and PRIMORYE, SAKHALIN, and the KURIL-OKHOTSK REGION in 2015

A review of the Amur and Primorye, Sakhalin, and the Kuril-Okhotsk region seismicity for 2015 is presented on the basis of data from the regional network of stationary seismic stations of the Sakhalin branch of the Geophysical Survey RAS with the involvement of data from adjacent seismological Russian and foreign agencies, as well as ten stations of the local network operating in the south Sakhalin. Parameters of 1643 seismic events have been determined, 126 of them are explosions. Focal mechanisms were calculated for 62 earthquakes. 48 earthquakes have shown a macroseismic effect. A map of the epicenters is presented, the distribution of the number N of crustal and deep-focus earthquakes by a magnitude, a total seismic energy ∑E for seismically active regions of three regions are given, in comparison with the average parameters N and ∑E for 20012014. For each region, an analysis of the parameters of the seismic regime in 2015 is given in comparison with long-term averages, the maximum and significant seismic events are described. The seismicity of the Priamurye and Primorye, Sakhalin, and the Kuril-Okhotsk region in 2015 can be characterized as a moderate one.

The Global Electric Circuit and Global Seismicity

Basing on the catalogue of earthquakes with a magnitude of M ≥ 4.5 for the period 1973–2017, a UT variation with an amplitude of ~10% in the number of earthquakes is revealed and compared with a UT variation in the ionospheric potential (IP) with an amplitude of ~18%. We demonstrate that the amplitude of the UT variation in the number of deep-focus earthquakes is greater compared with that of crustal earthquakes, reaching 19%. The UT of the primary maxima of both the IP (according to modern calculations) and of earthquake incidence coincides (near 17:00 UT) and is, by 2 h, ahead of the classical Carnegie curve representing the UT variation in the atmospheric electric field on the ground surface. The linear regression equation between these UT variations in the number of deep-focus earthquakes and the ionospheric potential is obtained, with a correlation coefficient of R = 0.97. The results support the idea that the processes of earthquake preparation are coupled to the functional processes of the global electric circuit and the generation of atmospheric electric fields. In particular, the observed increase in thunderstorm activity over earthquake preparation areas, provided by air ionization due to radon emanation, yields a clue as to why the global thunderstorm distribution is primarily continental. Another important conclusion is that, in observing the longitudinal distributions of earthquakes against the IP distribution, we automatically observe that all such events occur in local nighttime hours. Considering that the majority of earthquake precursors have their maximums at local night and demonstrating the positive deviation from the undisturbed value, we obtain a clue as to its positive correlation with variations in the ionospheric potential.

Contact of the Samoan Plume with the Tonga Subduction from Intermediate and Deep-Focus Earthquakes

The Tonga subduction zone in the south-west Pacific is the fastest convergent plate boundary in the world with the most active mantle seismicity. This zone shows unique tectonic features including Samoan volcanic lineament of plume-driven origin near the northern rim of the Tonga subducting slab. The proximity of the Samoa hotspot to the slab is enigmatic and invokes debates on interactions between the Samoa plume and the Tonga subduction. Based on long-term observations of intermediate and deep-focus Tonga earthquakes reported in the Global Centroid Moment Tensor (CMT) catalog, we provide novel detailed imaging of this region. Accurate traveltime residua of the P- and S-waves recorded at two nearby seismic stations of the Global Seismographic Network are inverted for the P- and S-wave velocities and their ratio and reveal their pronounced lateral variations. In particular, they differ for the southern and northern parts of the Tonga subduction region. While no distinct anomalies are detected in the southern Tonga segment, striking low-velocity anomalies associated with a high Vp/Vs ratio are observed in the northern Tonga segment close to the Samoa plume. These anomalies spread through the whole upper mantle down to depths of ~ 600 km. Together with the fast extension of the northern back-arc Lau Basin, slab deformation and geochemical enrichment in the northern Tonga region, they trace deep-seated magmatic processes and evidence an interaction of the Tonga subduction with the Samoa plume.

ANALISIS ASPEK PERPAJAKAN ATAS JASA SEWA KANTOR VIRTUAL

This study aims to analyze the taxation aspects of virtual office rental services. With the issuance of PMK-147/PMK.03/2017, it is hoped that taxpayers will find it easier to carry out their tax obligations related to virtual office rental services. Using a descriptive study approach, this qualitative research is expected to describe and understand the phenomenon of virtual office rental services with a deep focus. The study results indicate that there are still differences in the definition of a virtual office between taxpayers and the DGT, giving rise to the practice of imposing different virtual office rental taxes between taxpayers. Income from virtual office rental services is subject to Income Tax Article 4 paragraph (2), Income Tax Article 23, and Income Tax Article 4 paragraph (1). Thus, regulatory certainty is needed on the taxation of virtual office rental services.

Plan Across Borders

This chapter looks at promising regional cooperation efforts to de-escalate tensions heightened by climate change. Tackling problems like pandemics or climate change within the framework of traditional jurisdictional boundaries means that policymakers continue to treat these challenges like matters of domestic or local concern, rather than the transboundary threats that they are. Breaking down these barriers requires deep focus on cross-border solutions. For example, the climate change problem of “too little and too much water” demands transboundary consideration of evolving conditions in river basins and ocean fisheries. Risk reduction efforts that stretch across regions also offer good avenues for building disaster preparedness, including stockpiling, creating insurance risk pools, setting up systems for regional climate forecasting and early warning, and re-energizing multilateralism. Likewise, the most urgent transborder challenge of all, climate-induced migration, calls for ever greater global cooperation—not less.

Interpretation of military power in the context of realism paradigm

The article seeks to reveal the possibilities of a theoretical interpretation of power in the broad sense and military power in the narrow sense in the context of the realism paradigm, with a deep focus on including intangible resources in the interpretation of power. In the article, the interpretation of power is consciously grounded on the synthesis of power as resources and power as relation perspectives meanwhile applying this synthesis to the analysis of military power. Thus, military power is perceived as covering not only material but also non-material resources and as being contextual in nature. The article forms assumptions that the interpretation of military power depends on the security environment perception of the political and military elite: by changing warfare concepts and force employment methods they introduce military innovations, while military doctrines are an instrument of power conversion – through them the security environment perception is imparted and the structure of military power is changed. Such an interpretation of military power, combining different insights based on the paradigm of realism, allows the formation of an alternative approach to the interpretation of military power.

Unexpected Shallow Earthquake of August 1st, 2020 in the North of Indramayu, West Java, Indonesia

During the last one hundred years, there are no shallow seismicity in the north of Java. This area is dominated by intermediate and deep focus earthquakes due to the subducted Indo-Australian slab. An earthquake with magnitude ML 4.5 struck Indramayu, north of West Java on August 1, 2020. According to the Agency for Meteorology, Climatology, and Geophysics (BMKG), the earthquake was felt III MMI scale in Indramayu and its vicinity. We used waveform data from BMKG seismic station in West Java, then we picked P-and S-waves arrival times from each station and hypocenter location was determined by Geiger method. We have detected Pn before Pg phase on four BMKG seismic stations, indicating a shallow crustal earthquake. Our inversion show that the earthquake occurred in 6.1805° S, 108.2612° E with 5 km focus depth at 16:24:38 GMT+7. Our focal mechanism solution was determined by using moment tensor inversion shows a strike-slip faulting, which corresponds to the active fault in the north of Indramayu.

Clinical Scholars: Making Equity, Diversity and Inclusion Learning an Integral Part of Leadership Development

The plethora of persistent and pervasive health inequities in the United States is a Wicked Problem which threatens the health and wellbeing of all people. To dismantle them is no easy task, and requires a health care workforce practiced in leadership skill sets embracing a deep focus on areas of equity, diversity and inclusion (EDI). This chapter describes how the core competencies and curriculum of the Clinical Scholars Program have been designed to offer this set of skills. To start, the program’s foundational set of 25 competencies cover four domains (Personal, Interpersonal, Organizational, and Community & Systems) and include both more traditional leadership competencies as well as contemporary competencies focused on equity, diversity, and inclusion. The curriculum takes the set of 25 leadership and EDI competencies and breaks them down into learning sessions where participants listen, practice, and apply the ideas, behaviors, and mindsets. The leadership core and the EDI core of the curriculum exist both in tandem and in unison to provide the full Clinical Scholars experience. At times, sessions focus on one core or the other, and at times, both leadership and EDI are present in the learning of a session. Example learning sessions for each core and the weaving of the cores together are provided. Four challenges to creating an equity-centered leadership program are identified: 1. The personalized nature of the journey of self-development; 2. Shifting Mindsets and Skill Sets; 3. Piloting an evidence-based curriculum on EDI; and 4. Maintaining engagement with participants over time and across distance. A set of top recommendations for weaving EDI and Leadership learning are also offered. The chapter details the importance of meaningfully focusing on EDI when tackling modern, wicked problems.
