Quality Enhancement of Highly Degraded Music Using Deep Learning-Based Prediction Models for Lost Frequencies
Audio quality degradation can have many causes. For musical applications, this fragmentation may lead to highly unpleasant experiences. Restoration algorithms may be employed to reconstruct missing parts of the audio in a similar way as for image reconstruction-in an approach called audio inpainting. Current state-of-The art methods for audio inpainting cover limited scenarios, with well-defined gap windows and little variety of musical genres. In this work, we propose a Deep-Learning-based (DL-based) method for audio inpainting accompanied by a dataset with random fragmentation conditions that approximate real impairment situations. The dataset was collected using tracks from different music genres to provide a good signal variability. Our best model improved the quality of all musical genres, obtaining an average of 12.9 dB of PSNR, although it worked better for musical genres in which acoustic instruments are predominant
A Cluster-Based Method for Action Segmentation Using Spatio-Temporal and Positional Encoded Embeddings
A crucial task to overall video understanding is the recognition and localisation in time of different actions or events that are present along the scenes. To address this problem, action segmentation must be achieved. Action segmentation consists of temporally segmenting a video by labeling each frame with a specific action. In this work, we propose a novel action segmentation method that requires no prior video analysis and no annotated data. Our method involves extracting spatio-Temporal features from videos in samples of 0.5s using a pre-Trained deep network. Data is then transformed using a positional encoder and finally a clustering algorithm is applied with the use of a silhouette score to find the optimal number of clusters where each cluster presumably corresponds to a different single and distinguishable action. In experiments, we show that our method produces competitive results on Breakfast and Inria Instructional Videos dataset benchmarks
A Guide to Noxious Plants as an Educational Resource of Veterinary Medicine Students
The School of Veterinary UNRN is located in the town of Choele Choel (39° 17\u27S, 65° 39\u27W), in Northern Patagonia, Argentina. The climate is semi-arid with a historical average annual continental rainfall of 303 mm, with marked daily and seasonal temperature ranges. However, the type of vegetation that can be found in the area ranges fromxerophytic shrubs to hydrophytic vegetation because the arid plateau is crossed by the broad valley of RĂo Negro. Due to the topographic distribution of agricultural and livestock farms, the toxic plants for livestock may be found in the irrigated valleys or arid shrubby camps
Estrogenic and Anti-Inflammatory Activities of a Steroidal Indoxyl
The estrogenic and anti-inflammatory activities of 3-methoxy-16, 17-seco-16-norestra-1,3,5-trien-15-(2'-indoxyliden)-17-oic acid is reported. After intraperitoneal administration, the dose of this compound required to reduce swelling of the rat paw by 50% (ED50) was 14.1 mg/kg using the carrageenan-induced rat paw oedema anti-inflammatory assay method. Indomethacin had an ED50 of 3.2 mg/kg in this assay while dexamethasone had an ED50 of 1.7 mg/kg. The estrogenic activity of the compound after intramuscular administration in rats was 0.72 relative to diethylstilbestrol, when the two compounds were assayed at three dose levels of 1.0, 0.3 and 0.1 mg/kg.

A Cluster-Matching-Based Method for Video Face Recognition
Face recognition systems are present in many modern solutions and thousands
of applications in our daily lives. However, current solutions are not easily
scalable, especially when it comes to the addition of new targeted people. We
propose a cluster-matching-based approach for face recognition in video. In our
approach, we use unsupervised learning to cluster the faces present in both the
dataset and targeted videos selected for face recognition. Moreover, we design
a cluster matching heuristic to associate clusters in both sets that is also
capable of identifying when a face belongs to a non-registered person. Our
method has achieved a recall of 99.435% and a precision of 99.131% in the task
of video face recognition. Besides performing face recognition, it can also be
used to determine the video segments where each person is present.Comment: 13 page
