Bifurcation Analysis of a Stochastically Driven Limit Cycle

We establish the existence of a bifurcation from an attractive random equilibrium to shear-induced chaos for a stochastically driven limit cycle, indicated by a change of sign of the first Lyapunov exponent. This addresses an open problem posed by Kevin Lin and Lai-Sang Young, extending results by Qiudong Wang and Lai-Sang Young on periodically kicked limit cycles to the stochastic context

ANALISIS PENGALAMAN PENGGUNA PADA APLIKASI SANG KURIR DENGAN MENGGUNAKAN USABILITY TESTING DAN USER EXPERIENCE QUESTIONNAIRE (UEQ)

Sang Kurir merupakan aplikasi lokal yang dikembangkan di Desa Pesanggaran Kabupaten Banyuwangi. Aplikasi ini menyediakan jasa pelayanan seperti delivery makanan , layanan ojek dan jasa lainya yang memudahkan masyarakat Pesanggaran. Satu satu keberhasilan aplikasi mampu memberikan pengalaman yang baik dan respon positif dari para pengguna, sehingga untuk mengetahui pengalaman pengguna pada Sang Kurir perlu adanya analisis User Experience Questionnaire Experience dengan melakukan pengujian Usability Testing Testing menggunakan metode Scenario Task dan pengukuran User Experience Questionnaire Experience Questionnaire (UEQ). Pada pengujian Scenario Task terdapat 5 tugas yang harus dikerjakan oleh 10 responden sesuai dengan 4 parameter Scenario Task (Number of Click During Task Completion, Task Succes Rate, Error During Task Perfomance dan Time Per Completed Task). Pada pengukuran UEQ terdapat 6 skala (AttractivenessDaya Tarik, Efficiency, Percpicuit, Dependability, Stimulation, dan Novelty) dengan 26 item pertanyaan dan 85 responden . Dari hasil pengujian Scenario Task pada Number of Click During Task Completion rata-rata 5.18, parameter Task Succes Rate mendapatkan 96% keberhasilan, hasil Error During Task Perfomance mendapatkan persentase 13.75%. Dan hasil rata-rata Time Per Completed Task 22.04. Kemudian untuk pengukuran User Experience Questionnaire Experience Questionnaire berada pada level Benchmark mendapatkan level Above (Diatas Rata-rata) untuk semua skalanya. Sehingga pada hasil analisis aplikasi Sang Kurir mendapatkan respon yang baik bagi para pengguna

Somya Rupa (Babak 1)

Deskripsi karya : Dikisahkan Dewi Uma diiringi oleh para bidadari sedang mengasuh putranya yang bernama Sang Hyang Rare Kumara, didampingi oleh Sang Hyang Siwa di sorga (Siwaloka). Tiba-tiba Sang Hyang Rare Kumara terjatuh dari pangkuan ibundanya, yang mengakibatkan kepalanya pecah dan mengeluarkan darah segar. Seketika Dewi Uma merangkul kembali putranya yang masih bayi itu, namun anehnya darah Sang Hyang Rare Kumara berbau harum. Sertamerta dicicipinya darah tersebut oleh Dewi Uma. Melihat gelagat tak wajar itu Sang Hyang Siwa marah, beliau mengutuk Dewi Uma menjadi Dewi Durga, seorang raksasi yang sangat mengerikan, kemudian menyuruh Dewi Durga turun ke bumi menghuni kuburan (Setra Gandamayu). Pada suatu saat Sang Hyang Siwa sangat merindukan Dewi Uma. Karena rindunya yang tak tertahankan, maka beliau merubah wujutnya menjadi Sang Hyang Kala Rudra, seorang raksasa yang besar yang menakutkan. Sang Hyang Kala Rudra kemudian turun ke Marcapada (dunia) menemui istrinya, Dewi Durga. Pertemuan antara Sang Hyang Kala Rudra dan Dewi Durga mengakibatkan guncangan yang sangat luar biasa. Wabah penyakit menyebar ke mana-mana, banyak terjadi pembunuhan, kebakaran hutan, banjir, maupun gempa bumi. Sang Hyang Tri Semaya, yaitu Sang Hyang Brahma, Sang Hyang Wisnu, dan Sang Hyang Iswara, turun ke dunia untuk menetralisir keadaan tersebut dengan menyelenggarakan berbagai bentuk kesenian, yakni Sang Hyang Brahma menjadi Telek (peret), Sang Hyang Wisnu menjadi Topeng (tekes), Sang Hyang Iswara menjadi Barong (iswari) dan dalang (redep). Berkat peran Sang Hyang Trisemaya, maka keadaan dunia menjadiberangsur-angsur pulih kembali. Sang Hyang Kala Rudra dan Dewi Durga kembali ke wujud semula, yakni Sang Hyang Siwa dan Dewi Uma, yang berwajah lemah lembut (somya rupa). Selanjutnya kesenian dijadikan salah satu unsur tuntunan sekaligus tontonan

Influence of Quaternary Benzophenantridine and Protopine Alkaloids on Growth Performance, Dietary Energy, Carcass Traits, Visceral Mass, and Rumen Health in Finishing Ewes under Conditions of Severe Temperature-humidity Index.

Twenty Pelibuey×Katahdin ewes (35±2.3 kg) were used to determine the effects of the consumption of standardized plant extract containing a mixture of quaternary benzophenanthridine alkaloids and protopine alkaloids (QBA+PA) on growth performance, dietary energetics, visceral mass, and ruminal epithelial health in heat-stressed ewes fed with a high-energy corn-based diet. The basal diet (13.9% crude protein and 2.09 Mcal of net energy [NE] of maintenance/kg of dry matter) contained 49.7% starch and 15.3% neutral detergent fiber. Source of QBA+PA was Sangrovit RS (SANG) which contains 3 g of quaternary benzophenathridine and protopine alkaloids per kg of product. Treatments consisted of a daily consumption of 0 or 0.5 g SANG/ewe. Ewes were grouped by weight and assigned to 10 pens (5 pens/treatment), with two ewes per pen. The experimental period lasted 70 days. The mean temperature humidity index during the course of this experiment was 81.7±1.0 (severe heat stress). There were no treatment effects on water intake. Dry matter intake was not affected (p = 0.70) by treatments, but the group fed SANG had a numerically (11.2%) higher gain in comparison to the control group, SANG improved gain efficiency (8.3%, p = 0.04), dietary NE (5.2%, p<0.01) and the observed-to-expected NE (5.9%, p<0.01). Supplemental SANG did not affect (p≥0.12) carcass characteristics, chemical composition of shoulder, and organ weights (g/kg empty body weight) of stomach complex, intestines, and heart/lung. Supplemental SANG decreased liver weight (10.3%, p = 0.02) and increased visceral fat (16.9%, p = 0.02). Rumen epithelium of ewes fed SANG had lower scores for cellular dropsical degeneration (2.08 vs 2.34, p = 0.02), parakeratosis (1.30 vs 1.82, p = 0.03) and neutrophil infiltration (2.08 vs 2.86, p = 0.05) than controls. It is concluded that SANG supplementation helped ameliorate the negative effects of severe heat on growth performance of feedlot ewes fed high-energy corn-based diets. Improvement in energetic efficiency may have been mediated, in part, by anti-inflammatory effects of supplemental SANG and corresponding enhancement of nutrient uptake

Testosterone affects song modulation during simulated territorial intrusions in male black redstarts (Phoenicurus ochruros)

Although it has been suggested that testosterone plays an important role in resource allocation for competitive behavior, details of the interplay between testosterone, territorial aggression and signal plasticity are largely unknown. Therefore, we investigated if testosterone acts specifically on signals that communicate the motivation or ability of individuals to engage in competitive situations in a natural context. We studied the black redstart, a territorial songbird species, during two different life-cycle stages, the early breeding phase in spring and the non-breeding phase in fall. Male territory holders were implanted with the androgen receptor blocker flutamide (Flut) and the aromatase inhibitor letrozole (Let) to inhibit the action of testosterone and its estrogenic metabolites. Controls received a placebo treatment. Three days after implantation birds were challenged with a simulated territorial intrusion (STI). Song was recorded before, during and after the challenge. In spring, both treatment groups increased the number of elements sung in parts of their song in response to the STI. However, Flut/Let-implanted males reacted to the STI with a decreased maximum acoustic frequency of one song part, while placebo-implanted males did not. Instead, placebo-implanted males sang the atonal part of their song with a broader frequency range. Furthermore, placebo-, but not Flut/Let-implanted males, sang shorter songs with shorter pauses between parts in the STIs. During simulated intrusions in fall, when testosterone levels are naturally low in this species, males of both treatment groups sang similar to Flut/Let-implanted males during breeding. The results suggest that song sung during a territorial encounter is of higher competitive value than song sung in an undisturbed situation and may, therefore, convey information about the motivation or quality of the territory holder. We conclude that testosterone facilitates context-dependent changes in song structures that may be honest signals of male quality in black redstarts
