PREDIKSI CURAH HUJAN WILAYAH MENGGUNAKAN METODE JARINGAN SARAF TIRUAN (JST) BACKPROPAGATION DI DAS RONGKONG

Hidrologi merupakan salah satu faktor yang diperlukan untuk penyelesaian suatu permasalahan sumber daya air. Analisa curah hujan sangatlah diperlukan sebelum melakukan suatu prediksi. DAS Rongkong seluas 1728,034 Km²yang terletak di Kabupaten Luwu Utara mengalami permasalahan tentang peralihan tata guna lahan yang menyebabkan kemampuan infiltrasinya menjadi berkurang. Tujuan dari penelitian ini adalah untuk prediksi curah hujan di DAS Rongkong dan mengetahui perbandingan antara data lapangan dengan data hasil prediksi menggunakan Metode Jaringan Syaraf Tiruan (JST) Back Propagation. Berdasarkan hasil penelitian diperoleh hasil pada tahun 2022 bulan Januari: 66 mm, Februari : 25 mm, Maret : 22 mm, April : 19 mm, Mei : 22 mm, Juni : 40 mm, Juli : 18 mm, Agustus : 18 mm, September : 66 mm, Oktober : 18 mm, November : 30 mm, Desember : 67 mm. Berdasarkan Grafik data lapangan dengan data hasil prediksi Metode JST Pada bulan Januari, September dan Desember curah hujan wilayah yang dihasilkam mengalami kenaikan ,Sedangkan Pada bulan Februari, Maret, April, Mei, Juni, Juli, Agustus dan November curah hujan wilayah yang dihasuilkan mengalami penurunan. Sehingga Rata-rata selisih yang dihasilkan sebesar 13,83 mm

NK4, a four-kringle antagonist of HGF, inhibits spreading and invasion of human pancreatic cancer cells

Because of the highly aggressive behaviour, i.e. invasive, disseminative and metastatic properties, the outcome for patients with pancreatic cancer is morbid. A better understanding and interference with the malignant behaviour of pancreatic cancer may provide new directions for treatment. We report here the induction of highly motile and invasive properties in human pancreatic cancer cells by hepatocyte growth factor (HGF) and blockage of these properties by NK4, a newly identified antagonist for HGF. In all of eight human pancreatic cancer cell lines we used (AsPC-1, BxPC-3, H-48N, KP-1N, KP-2, KP-3, MIA PaCa-2 and SUIT-2 cells), the c-Met/HGF receptor was expressed at varying levels. Although weak mitogenic activity of HGF was seen only in SUIT-2 and KP-3 cells, HGF strongly stimulated migration and invasion of these pancreatic cancer cells, except for BxPC-3 and MIA PaCa-2 cells. In contrast, migration and invasion potently induced by HGF in KP-1N, KP-3 and SUIT-2 cells were inhibited by NK4. The invasion of SUIT-2 cells was also potently stimulated with the influence of cocultured pancreatic fibroblasts and by ascitic fluid obtained after pancreatic cancer resection, however, invasiveness of the cancer cells in such conditions was practically abolished by NK4. Consistently, the ascitic fluid in patients who had undergone pancreatic cancer surgery contained high levels of HGF. These findings mean that HGF is probably involved in invasion, dissemination, and metastasis of pancreatic cancer, particularly through tumour-stromal interaction and after resection of the pancreatic cancer. NK4, an effective antagonist of HGF, may prove to have the potential for anti-invasion/metastasis. © 2001 Cancer Research Campaign http://www.bjcancer.co

Recording electrical activity from the brain of behaving octopus

: Octopuses, which are among the most intelligent invertebrates,1,2,3,4 have no skeleton and eight flexible arms whose sensory and motor activities are at once autonomous and coordinated by a complex central nervous system.5,6,7,8 The octopus brain contains a very large number of neurons, organized into numerous distinct lobes, the functions of which have been proposed based largely on the results of lesioning experiments.9,10,11,12,13 In other species, linking brain activity to behavior is done by implanting electrodes and directly correlating electrical activity with observed animal behavior. However, because the octopus lacks any hard structure to which recording equipment can be anchored, and because it uses its eight flexible arms to remove any foreign object attached to the outside of its body, in vivo recording of electrical activity from untethered, behaving octopuses has thus far not been possible. Here, we describe a novel technique for inserting a portable data logger into the octopus and implanting electrodes into the vertical lobe system, such that brain activity can be recorded for up to 12 h from unanesthetized, untethered octopuses and can be synchronized with simultaneous video recordings of behavior. In the brain activity, we identified several distinct patterns that appeared consistently in all animals. While some resemble activity patterns in mammalian neural tissue, others, such as episodes of 2 Hz, large amplitude oscillations, have not been reported. By providing an experimental platform for recording brain activity in behaving octopuses, our study is a critical step toward understanding how the brain controls behavior in these remarkable animals
