Coronal loop hydrodynamics. The solar flare observedon November 12 1980 revisited: the UV line emission

We revisit a well-studied solar flare whose X-ray emission originating from a simple loop structure was observed by most of the instruments on board SMM on November 12 1980. The X-ray emission of this flare, as observed with the XRP, was successfully modeled previously. Here we include a detailed modeling of the transition region and we compare the hydrodynamic results with the UVSP observations in two EUV lines, measured in areas smaller than the XRP rasters, covering only some portions of the flaring loop (the top and the foot-points). The single loop hydrodynamic model, which fits well the evolution of coronal lines (those observed with the XRP and the \FeXXI 1354.1 \AA line observed with the UVSP) fails to model the flux level and evolution of the \OV 1371.3 \AA line.Comment: A&A, in press, 6 pages, 5 figure

Unified processing of constraints for interactive simulation

International audienceThis paper introduces a generic way of dealing with a set of different constraints (bilateral, unilateral, dry friction) in the context of interactive simulation. We show that all the mentioned constraints can be handled within a unified framework: we define the notion of generalized constraints, which can be derived into most classical constraints types. The solving method is based on an implicit treatment of constraints that provides good stability for interactive applications using deformable models and rigid bodies. Each constraint law is expressed in constraint subspace, making constraint evaluation much easier. A global solution is calculated using an iterative process that takes into account the mechanical coupling between the constraints. Various examples, from basic to more complex, show the practical advantage of using generalized constraints, as a way of creating heterogeneously constrained systems, as well as the scalability of the proposed method

P2A0 Post Seksio Sesarea Transperitoneal Profunda Dengan Sindrom Sheehan Et Causa Perdarahan Pasca Persalinan Dini Et Causa Atonia Uteri

Sindrom Sheehan (SS) adalah hypopituitarism pasca persalinan akibat nekrosis iskemik yang menghasilkan hipotensi akibat perdarahan masif saat atau sesudah persalinan. Riwayat perdarahan pasca persalinan (PPP), gagal menyusui, dan amenore sekunder penting sebagai penunjuk diagnosis. Sindrom Sheehan sering berkembang dan terdiagnosis lambat. Diagnosis dini dan pengobatan yang sesuai sangatlah penting untuk menurunkan morbiditas dan mortalitas pasien. Laporan kasus ini menjelaskan seorang wanita usia 28 tahun, dengan PPP 5 jam post seksio sesarea transperitoneal profunda (SSTP) di luar atas indikasi (ai) gawat janin. Pemeriksaan fisik didapatkan keadaan umum buruk, kesadaran somnolen, tekanan darah 100/70 mmHg, nadi 120 kali/menit, pernapasan 24 kali/menit, suhu 36,8 0C, dan konjungtiva palpebra anemis. Pemeriksaan obstetrik didapatkan tinggi fundus uteri (TFU) tidak teraba, tidak ada kontraksi, dan tidak ada perdarahan aktif. Hasil laboratorium menunjukkan Hemoglobin 3,5 g/dL. Dilakukan observasi tanda-tanda vital, pemberian O2 10 L sungkup, intravena fluid drip (IVFD) dua jalur berupa guyur ringer laktat (RL) dan RL + oksitosin 20 IU 10 tetes/menit, pemasangan kateter urin menetap dengan evaluasi input dan output cairan, dan laparatomi cito berupa histerektomi subtotal. Pasca operasi pasien dirawat di Intensive Care Unit (ICU) 19 hari lalu dilanjutkan perawatan di bangsal selama 3 hari. Hingga akhir perawatan pasien komposmentis, air susu ibu (ASI) tidak keluar, dan tidak ditemukan adanya perdarahan pervaginam

The three-body recombination of a condensed Bose gas near a Feshbach resonance

In this paper, we study the three-body recombination rate of a homogeneous dilute Bose gas with a Feshbach resonance at zero temperature. The ground state and excitations of this system are obtained. The three-body recombination in the ground state is due to the break-up of an atom pair in the quantum depletion and the formation of a molecule by an atom from the broken pair and an atom from the condensate. The rate of this process is in good agreement with the experiment on $^{23}$Na in a wide range of magnetic fields.Comment: 10 pages, 2 figures, to be published in Phys. Rev.

We report on the development of Silicon PhotoMultipliers (SiPM) at the Fondazione Bruno Kessler (FBK)-irst (Trento, Italy) in the framework of a collaboration with INFN. Device geometry and technology are resumed, and selected results from the characterization of SiPM prototypes from three production batches are reported, including static, dynamic, and noise properties, as well as photodetection efficiency

The INFN-FBK "Phase-2" R&D program

We report on the 3-year INFN ATLAS-CMS joint research activity in collaboration with FBK, started in 2014, and aimed at the development of new thin pixel detectors for the High Luminosity LHC Phase-2 upgrades. The program is concerned with both 3D and planar active-edge pixel sensors to be made on 6" p-type wafers. The technology and the design will be optimized and qualified for extreme radiation hardness (2×1016 neq cm-2). Pixel layouts compatible with present (for testing) and future (RD53 65nm) front-end chips of ATLAS and CMS are considered. The paper covers the main aspects of the research program, from the sensor design and fabrication technology, to the results of initial tests performed on the first prototypes. © 2015 Elsevier B.V

Testbeam and Laboratory Characterization of CMS 3D Pixel Sensors

The pixel detector is the innermost tracking device in CMS, reconstructing interaction vertices and charged particle trajectories. The sensors located in the innermost layers of the pixel detector must be upgraded for the ten-fold increase in luminosity expected with the High- Luminosity LHC (HL-LHC) phase. As a possible replacement for planar sensors, 3D silicon technology is under consideration due to its good performance after high radiation fluence. In this paper, we report on pre- and post- irradiation measurements for CMS 3D pixel sensors with different electrode configurations. The effects of irradiation on electrical properties, charge collection efficiency, and position resolution of 3D sensors are discussed. Measurements of various test structures for monitoring the fabrication process and studying the bulk and surface properties, such as MOS capacitors, planar and gate-controlled diodes are also presented.Comment: 14 page
