Deep Remix: Remixing Musical Mixtures Using a Convolutional Deep Neural Network
Audio source separation is a difficult machine learning problem and
performance is measured by comparing extracted signals with the component
source signals. However, if separation is motivated by the ultimate goal of
re-mixing then complete separation is not necessary and hence separation
difficulty and separation quality are dependent on the nature of the re-mix.
Here, we use a convolutional deep neural network (DNN), trained to estimate
'ideal' binary masks for separating voice from music, to perform re-mixing of
the vocal balance by operating directly on the individual magnitude components
of the musical mixture spectrogram. Our results demonstrate that small changes
in vocal gain may be applied with very little distortion to the ultimate
re-mix. Our method may be useful for re-mixing existing mixes

Skripsi. Surakarta: Fakultas Keguruan dan Ilmu Pendidikan. Universitas Sebelas Maret. Mei 2015.Penelitian ini bertujuan untuk mengetahui: (1) pengaruh penggunaan metode Student Teams Achievement Divission (STAD) terhadap hasil belajar siswa (2) pengaruh penggunaan metode Numbered Head Together (NHT) terhadap hasil belajar siswa (3) perbedaan pengaruh penggunaan metode Student Teams Achievement Divission (STAD) dan metode Numbered Head Together (NHT) terhadap hasil belajar siswa. Adapun penelitian ini dilakukan pada kelas XI IPS di SMA Negeri 1 Sambungmacan. Penelitian ini bersifat eksperimental. Populasi penelitian ini adalah seluruh siswa SMA Negeri 1 Sambungmacan Tahun Pelajaran 2014/2015. Sampel penelitian sebanyak tiga kelas diambil dengan teknik multistage cluster random sampling. Teknik pengumpulan data menggunakan dokumentasi, tes, dan angket. Teknik analisis data menggunakan analisis uji dua pihak.Hasil penelitian menunjukkan: (1) Ada perbedaan penggunaan metode STAD dan metode NHT terhadap hasil belajar sosiologi siswa kelas XI IPS SMA Negeri 1 Sambungmacan. Hal ini dapat dilihat dari hasil analisis data yang menunjukkan rata-rata metode STAD sebesar 13,57 dan rata-rata metode NHT sebesar 15,80 dengan ρ= 0.065 (cukup signifikan). (2) Ada pengaruh penggunaan metode STAD dan metode NHT terhadap hasil belajar sosiologi siswa kelas XI IPS SMA Negeri 1 Sambungmacan. Hal ini dapat dilihat dari hasil analisis data yang menunjukkan harga F= 3.441; ρ= 0.065 (cukup signifikan). (3) Besar pengaruh penggunaan metode STAD dan metode NHT terhadap hasil belajar sosiologi siswa kelas XI IPS SMA Negeri 1 Sambungmacan sebesar 22%.Kesimpulan penelitian adalah ada perbedaan penggunaan metode STADdan metode NHT terhadap hasil belajar siswa kelas XI IPS SMA Negeri 1 Sambungmacan. Nilai rata-rata kelas NHT lebih tinggi daripada nilai rata-rata pada kelas STAD. Metode belajar memberikan pengaruh terhadap hasil belajar sosiologi siswa yaitu sebesar 22% sedangkan 78% dipengaruhi oleh faktor lain
Angiotensin type-2 (AT-2)-receptor activation reduces renal fibrosis in cyclosporine nephropathy: evidence for blood-pressure independent effect
Compound 21 (C21), selective agonist of AT2 receptors, shows antinflammatory effects in hypertension and nephroprotection in diabetes. The aim of this study was to evaluate the effects of C21 in cyclosporine nephropathy, which is characterized mainly by tubulo-interstitial fibrosis. Ten days before and during the experimental periods, low-salt diet was administered to Sprague Dawley rats. Cyclosporine-A (15mg/kg/day, i.p.) and cyclosporine-A plus C21 (0.3 mg/kg /day, i.p) were administered for 1 and 4 weeks. Control groups was left without any treatment. Blood pressure (plethysmographic method) and 24 hour albuminuria were measured once a week. At the end of the experiments, the kidneys were excised for histomorphometric analysis of renal fibrosis and for immunohistochemical evaluation of inflammatory infiltrates and type I and IV collagen expression.After 1 and 4 weeks, the rats treated with cyclosporine showed a significant increase (p <0.01) in blood pressure, no significant changes in albuminuria, a significant increase (p <0.01) in glomerular and tubulo-interstitial fibrosis and inflammatory infiltrates as compared to the control rats. Treatment with C21 did not modify the cyclosporine dependent increase of blood pressure, which was higher than in control rats, but after 4 weeks of treatment significantly reduced (p <0.01) glomerular and tubulo-interstitial fibrosis, type 1 collagen expression and macrophage infiltration, as compared to rats treated with cyclosporine.The administration of C21 showed a protective effect on cyclosporine nephropathy, decreasing renal fibrosis and macrophage infiltration. These data suggest that C21 may counteract tubulo-interstitial fibrosis, the most potent predictor of the progression of renal diseases
Comorbid depressive disorders in ADHD. the role of ADHD severity, subtypes and familial psychiatric disorders
ObjectiveaaTo evaluate the presence of Major Depressive Disorder (MDD) and Dysthymic Disorder (DD) in a sample of Italian children with Attention Deficit Hyperactivity Disorder (ADHD) and to explore specific features of comorbid depressive disorders in ADHD. MethodsaaThree hundred and sixty-six consecutive, drug-naïve Caucasian Italian outpatients with ADHD were recruited and comorbid disorders were evaluated using DSM-IV-TR criteria. To evaluate ADHD severity, parents of all children filled out the ADHD Rating Scale. Thirty-seven children with comorbid MDD or DD were compared with 118 children with comorbid conduct disorder and 122 without comorbidity for age, sex, IQ level, family psychiatric history, and ADHD subtypes and severity. Resultsaa42 of the ADHD children displayed comorbid depressive disorders: 16 exhibited MDD, 21 DD, and 5 both MDD and DD. The frequency of hyperactive-impulsive subtypes was significantly lower in ADHD children with depressive disorders, than in those without any comorbidity. ADHD children with depressive disorders showed a higher number of familial psychiatric disorders and higher score in the Inattentive scale of the ADHD Rating Scale, than children without any comorbidity. No differences were found for age, sex and IQ level between the three groups. Conclusions: Consistent with previous studies in other countries, depressive disorders affect a significant proportion of ADHD children in Italy. Patient assessment and subsequent treatment should take into consideration the possible presence of this comorbidity, which could specifically increase the severity of ADHD attention problems
