    Demam Berdarah Dengue (DBD) disebabkan oleh virus dan disebarkan oleh nyamuk. Penyakit ini adalah salah satu masalah bagi kesehatan masyarakat Indonesia yang cenderung terus menyebar dengan meningkatnya mobilitas dan kepadatan populasi. Dari tahun 2009 sampai dengan 2011 kasus DBD selalu ditemukan di wilayah kerja Puskesmas Martapura. Jika dilihat dari stratifikasi kasus DBD per kelurahan/desa tahun 2012, terdapat 1 kelurahan dan 3 desa yang termasuk dalam kategori daerah endemis DBD serta 7 desa yang termasuk dalam kategori daerah sporadis DBD. Belum pernah dilakukan pemeriksaan House Indeks (HI) oleh petugas P2DBD Puskesmas Martapura dan Dinas Kesehatan Kabupaten Banjar di wilayah kerja Puskesmas Martapura. Penelitian ini merupakan penelitian observasional analitik untuk mengetahui perbedaan HI daerah endemis DBD dengan daerah sporadis DBD di wilayah kerja UPT Puskesmas Martapura. Subjek penelitian adalah HI daerah endemis dan sporadis yang diuji dengan uji statistik Independent 2-samples t-test. Hasil menunjukkan bahwa tidak ada perbedaan HI antara daerah endemik dan sporadis dengue di wilayah kerja Puskesmas Martapura pada tahun 2012

    Correlation Between Gender, Age, Education Level, and Working Status with Anti-tuberculosis Drug Uses (OATS) in Patients with Lung Tb in Indonesia 2013

    Lung TB is still being a public health problem in the world. Lung TB disease many attack age group productive. Most of who are from the group socio-economic and low levels of education that low. The low coverage recovery rates have had a negative impact on public health program achievement and success because it still gives an opportunity for transmitting Lung TB to other members of the family and community around it. To achieve recovery required order or loyalty treatment for every patient. Loyalty patients in medication dose without consultation OATS influenced by many factors. This research aims to analyze factors which affect the (OATS) Anti Tuberculosis uses in patients with Lung TB in Indonesia (The 33 provinces at the consecutive Indonesia Fundamental Health Research Survey in 2013).  This research used a non-interference study with cross-sectional approach. A sample of research is household\u27s members at the age of 15 consecutive that was diagnosed with Lung TB through inspection sputum and/or photo Lung by health workers through an interview. This research showed that most of pulmonary tuberculosis patients in the male gender (52.7%), the range of the largest age group of 35-44 years (21.3%), the highest educational level in the low educational level (73.9%), work status many in the working group (60.1%), and pulmonary tuberculosis patients more do not use OATS 60.4%. Logistic regression analysis test result shows, there is a significant correlation between genders, age, levels of education with the use of OATS. No significant relationship between working status in patients with Lungs TB and the use of OATS (p-value= 0.454). The characteristics patients with Lung TB (gender, age, levels of education) are the factors that influence significantly to this research and statistic, while status work is not significantly influenced in patients with Lung TB in Indonesia

    Data-driven image color theme enhancement

    Proceedings of the 3rd ACM SIGGRAPH Asia 2010, Seoul, South Korea, 15-18 December 2010It is often important for designers and photographers to convey or enhance desired color themes in their work. A color theme is typically defined as a template of colors and an associated verbal description. This paper presents a data-driven method for enhancing a desired color theme in an image. We formulate our goal as a unified optimization that simultaneously considers a desired color theme, texture-color relationships as well as automatic or user-specified color constraints. Quantifying the difference between an image and a color theme is made possible by color mood spaces and a generalization of an additivity relationship for two-color combinations. We incorporate prior knowledge, such as texture-color relationships, extracted from a database of photographs to maintain a natural look of the edited images. Experiments and a user study have confirmed the effectiveness of our method. © 2010 ACM.postprin

    Nonlinear Response of a Kondo system: Direct and Alternating Tunneling Currents

    Full text link
    Non - equilibrium tunneling current of an Anderson impurity system subject to both constant and alternating electric fields is studied. A time - dependent Schrieffer - Wolff transformation maps the time - dependent Anderson Hamiltonian onto a Kondo one. Perturbation expansion in powers of the Kondo coupling strength is carried out up to third order, yielding a remarkably simple analytical expression for the tunneling current. It is found that the zero - bias anomaly is suppressed by an ac - field. Both dc and the first harmonic are equally enhanced by the Kondo effect, while the higher harmonics are relatively small. These results are shown to be valid also below the Kondo temperature.Comment: 7 pages, RevTeX, 3 PS figures attached, the article has been significantly developed: time - dependent Schrieffer - Wolff transformation is presented in the full form, the results are applied to the change in the direct current induced by an alternating field (2 figures are new

    Unconventional Superconductivity in Heavy Fermion Systems

    Full text link
    We review the studies on the emergent phases of superconductvity and magnetism in the ff-electron derived heavy-fermion (HF) systems by means of the nuclear-quadrupole-resonance (NQR) under pressure. These studies have unraveled a rich variety of the phenomena in the ground state of HF systems. In this article, we highlight the novel phase diagrams of magnetism and unconventional superconductivity (SC) in CeCu2_2Si2_2, HF antiferromagnets CeRhIn5_5, and CeIn3_3. A new light is shed on the difference and common features on the interplay between magnetism and SC on the magnetic criticality.Comment: 15 pages, 13 figures, to appear in J. Phys. Soc.

    Suppression of Kondo effect in a quantum dot by external irradiation

    Full text link
    We demonstrate that the external irradiation brings decoherence in the spin states of the quantum dot. This effect cuts off the Kondo anomaly in conductance even at zero temperature. We evaluate the dependence of the DC conductance in the Kondo regime on the power of irradiation, this dependence being determined by the decoherence.Comment: 4 pages, 1 figur

    Strong-field terahertz-optical mixing in excitons

    Get PDF
    Driving a double-quantum-well excitonic intersubband resonance with a terahertz (THz) electric field of frequency \omega_{THz} generated terahertz optical sidebands \omega=\omega_{THz}+\omega_{NIR} on a weak NIR probe. At high THz intensities, the intersubband dipole energy which coupled two excitons was comparable to the THz photon energy. In this strong-field regime the sideband intensity displayed a non-monotonic dependence on the THz field strength. The oscillating refractive index which gives rise to the sidebands may be understood by the formation of Floquet states, which oscillate with the same periodicity as the driving THz field.Comment: 4 pages, 6 figure

    The Anderson Model out of equilibrium: Time dependent perturbations

    Full text link
    The influence of high-frequency fields on quantum transport through a quantum dot is studied in the low-temperature regime. We generalize the non crossing approximation for the infinite-U Anderson model to the time-dependent case. The dc spectral density shows asymmetric Kondo side peaks due to photon-assisted resonant tunneling. As a consequence we predict an electron-photon pump at zero bias which is purely based on the Kondo effect. In contrast to the resonant level model and the time-independent case we observe asymmetric peak amplitudes in the Coulomb oscillations and the differential conductance versus bias voltage shows resonant side peaks with a width much smaller than the tunneling rate. All the effects might be used to clarify the question whether quantum dots indeed show the Kondo effect.Comment: 13 pages, REVTEX 3.0, 5 figure
