    Spectral Difference Equations Satisfied by KP Soliton Wavefunctions

    Full text link
    The Baker-Akhiezer (wave) functions corresponding to soliton solutions of the KP hierarchy are shown to satisfy eigenvalue equations for a commutative ring of translational operators in the spectral parameter. In the rational limit, these translational operators converge to the differential operators in the spectral parameter previously discussed as part of the theory of "bispectrality". Consequently, these translational operators can be seen as demonstrating a form of bispectrality for the non-rational solitons as well.Comment: to appear in "Inverse Problems

    Spin Calogero Particles and Bispectral Solutions of the Matrix KP Hierarchy

    Full text link
    Pairs of n×nn\times n matrices whose commutator differ from the identity by a matrix of rank rr are used to construct bispectral differential operators with r×rr\times r matrix coefficients satisfying the Lax equations of the Matrix KP hierarchy. Moreover, the bispectral involution on these operators has dynamical significance for the spin Calogero particles system whose phase space such pairs represent. In the case r=1r=1, this reproduces well-known results of Wilson and others from the 1990's relating (spinless) Calogero-Moser systems to the bispectrality of (scalar) differential operators. This new class of pairs (L,Λ)(L, \Lambda) of bispectral matrix differential operators is different than those previously studied in that LL acts from the left, but Λ\Lambda from the right on a common r×rr\times r eigenmatrix.Comment: 16 page

    Analisis Isi Harian Tribun Timur dalam Pemberitaan Terkait Jurnalistik Islam

    Pokok permasalahan yang di bahas dalam skripsi ini adalah Bagaimana format pemberitaan harian Tribun Timur dan apa saja pegangan yang diberikan kepada setiap jurnalisnya. Bagaimana pemberitaan harian Tribun Timur dalam menyikapi kasus yang menyangkut umat muslim serta bagaimana mekanisme harian Tribun Timur dalam mengangkat berita-berita yang mengandung nilai-nilai Islam. Berdasarkan pokok permasalahan tersebut, maka tujuan penulisan skripsi ini adalah untuk mengetahui apa sebenarnya jurnalistik Islam itu dan yang membedakannya dengan jurnalistik umum. Mengetahui pemberitaan harian Tribun Timur akan sikapnya dalam menanggapi kasus dan kegiatan yang menyangkut umat muslim. Di samping itu yang paling penting memahami mekanisme yang dibentuk Tribun Timur dalam mengangkat berita-berita yang mengandung nilai-nilai Islam. Untuk memecahkan beberapa masalah tersebut, maka penulis menggunakan metode pengumpulan data dengan mengambil sampel Koran yang sesuai dengan yang diteliti, teknik wawancara (dengan mewawancarai narasumber yang memang berkompoten dalam masalah ini). Untuk menguatkan referensi dan pemahaman akan maksud dari penelitian yang hendak dilakukan, penulis melakukan kajian pustaka pada buku-buku tertentu dan sesekali mencari bahan tambahan di Internet. Berdasarkan hasil pengamatan penulis di beberapa edisi Koran selama ini dengan dibantu hasil wawancara ternyata tidak serta merta semua media umum itu memiliki sistem kerja penerbitan berita yang hanya bersifat umum saja. Ada juga media umum yang nyatanya secara tidak langsung lewat pemberitaannya dengan isuisu yang diangkat memberikan informasi secara meluas dan berbobot tentang aktivitas dan ritunitas umat muslim. Memang ternyata jurnalistik umum dan jurnalistik Islam itu tidak jauh berbeda, cuma yang membedakan hanya kebijakan redaksional yang dibangun dan sistem yang digunakan dalam menarik minat pembaca untuk mau membaca hasil dari media tersebu

    Determinan Pemberian Asi Eksklusif di Kabupaten Barito Kuala Kalimantan Selatan

    Full text link
    Pemberian ASI di Indonesia saat ini masih memprihatinkan. Hal ini disebabkan presentasi bayi yang menyusu eksklusif sampai dengan 6 bulan hanya 15,3%. Tujuan penelitian adalah mengetahui faktor-faktor yang berhubungan dengan pemberian ASI Eksklusif di Desa Tanjung Harapan Kecamatan Alalak tahun 2015. Metode penelitian ini menggunakan jenis penelitin analitik, dengan pendekatan cross sectional. Populasi penelitin adalah seluruh ibu-ibu yang memiliki bayi umur 7-24 bulan di Desa Tanjung Harapan sebanyak 55 orang dan data dikumpulkan menggunakan kuesioner. Analisis data menggunakan uji statistik chi-squere dengan taraf signifikan 0,05. Hasil penelitian ini menunjukan ada hubungan antara pengetahuan dan tingkat pendidikan dengan pemberian ASI Eksklusif. Tidak ada hubungan antara tempat persalinan dengan pemberian ASI Eksklusif. Disarankan agar petugas meningkatkan penyuluhan tentang pemberian ASI Ekslusif pada masyarakat, keluarga dan para ibu hamil dan menyusui untuk meningkatkan pengetahuan agar ibu dapat memberikan ASI Eksklusif kepada bayinya

    Bispectrality of N-Component KP Wave Functions: A Study in Non-Commutativity

    No full text
    A wave function of the N-component KP Hierarchy with continuous flows determined by an invertible matrix H is constructed from the choice of an MN-dimensional space of finitely-supported vector distributions. This wave function is shown to be an eigenfunction for a ring of matrix differential operators in x having eigenvalues that are matrix functions of the spectral parameter z. If the space of distributions is invariant under left multiplication by H, then a matrix coefficient differential-translation operator in z is shown to share this eigenfunction and have an eigenvalue that is a matrix function of x. This paper not only generates new examples of bispectral operators, it also explores the consequences of non-commutativity for techniques and objects used in previous investigations

    Responsive, Integrity, Morality and Fairness Law Enforcement as Social Change Instrument

    Full text link
    This article reviews the essence of law enforcement as social change instrument. Law in the context of Indonesia that embrace democratic system is upholding the justice values in it that fairness principles for all Indonesian people. As positive law in a legal state, law enforcement is required to be professional, proportional, good, fair, and wisely so in accordance with the rules of expediency, kindness and equality in the law itself. The outcomes of the research indicate that law and community cannot be separated, for law the community is a resource that gives life (to nature) and move the law. The communities live the law with the values, ideas, concepts. And also contribute the community to implement the law

    Biobanking of Endangered Mammalian Gametes and Embryos: A Review

    Get PDF
    The wealth of fauna resources has a strategic role in realizing the sovereignty and independence of the nation, so it needs to be preserved. Mammals contribute various ecological functions essential to human welfare, including sustaining energy flows and productivity and producing a different kind of biodiversity that is currently approaching extinction yet still exists. Animal biobanking is mostly focused on spermatozoa, oocytes, and embryos in various faunas, which is very relevant and an essential idea for producing healthy and sustainable populations. The quality of reproduction of local fauna with substantial economic value has also been increasingly degraded in recent years, so an accelerated effort in the field of conservation is needed, including integrating the latest technology with conservation efforts. However, the development of biobanking technology for endangered mammals still needs to be improved in its studies and innovations. The authors examine this issue since there is still information that has to be enhanced on the use of reproductive biotechnology techniques that center on the biobanking of animal gametes and embryos, particularly those of endangered mammals. This article provides information on the biobanking of sperm, oocytes, and embryos in endangered mammals
