Particle-level pileup subtraction for jets and jet shapes

We present an extension to the jet area-based pileup subtraction for both jet kinematics and jet shapes. A particle-level approach is explored whereby the jet constituents are corrected or removed using an extension of the methods currently being employed by the LHC experiments. Several jet shapes and nominal jet radii are used to assess the performance in simulated events with pileup levels equivalent to approximately 30 and 100 interactions per bunch crossing, which are characteristic of both the LHC Run I and Run II conditions. An improved performance in removing the pileup contributions is found when using the new subtraction method. The performance of the new procedure is also compared to other existing methods

Dynamic regulation of RAS and RAS signaling

RAS proteins regulate most aspects of cellular physiology. They are mutated in 30% of human cancers and 4% of developmental disorders termed Rasopathies. They cycle between active GTP-bound and inactive GDP-bound states. When active, they can interact with a wide range of effectors that control fundamental biochemical and biological processes. Emerging evidence suggests that RAS proteins are not simple on/off switches but sophisticated information processing devices that compute cell fate decisions by integrating external and internal cues. A critical component of this compute function is the dynamic regulation of RAS activation and downstream signaling that allows RAS to produce a rich and nuanced spectrum of biological outputs. We discuss recent findings how the dynamics of RAS and its downstream signaling is regulated. Starting from the structural and biochemical properties of wild-type and mutant RAS proteins and their activation cycle, we examine higher molecular assemblies, effector interactions and downstream signaling outputs, all under the aspect of dynamic regulation. We also consider how computational and mathematical modeling approaches contribute to analyze and understand the pleiotropic functions of RAS in health and disease

Pengaruh Metil Metsulfuron terhadap Sel Darah Merah Ikan Patin Siam (Pangasius Hypopthalmus)

Penggunaan herbisida yang tidak efektif berpotensi menjadi racun pada ikan yang dibudidayakan di area persawahan. Herbisida berbahan aktif metil metsulfuron merupakan herbisida sistemik dan selektif untuk tanaman padi. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi metil metsulfuron 0; 15,6 dan 39 ppm terhadap kerusakan sel darah merah dan persentase hematokrit patin siam (Pangasius hypopthalmus). Hasil penelitian menunjukkan sel darah merah patin siam yang terpapar metil metsulfuron pada konsentrasi 15,6 ppm dan 39 ppm, membentuk lipofuscin pada inti sel, seroid pada permukaan sitoplasma dan nilai hematokrit 19,76 dan 14,80 % sebagai indikasi terjadinya anemia

Neochamberlainia, a new name for Chamberlainia Artabe, Zamuner & D. W. Stev. (Zamiaceae) non Chamberlainia Grout (Brachytheciaceae)

Artabe et al. (2005) described a new fossil cycad genus, Chamberlainia, from the Allen Formation (Late Cretaceous) of Baja de Santa Rosa, Río Negro Province, Argentina. Unfortunately, this name is preoccupied by a moss genus in the Brachytheciaceae, described by Grout (1928). Thus, Chamberlainia Artabe, Zamuner & D. W. Stev. is a later homonym (Art. 53.1, ICBN Vienna) and a new name is required.Facultad de Ciencias Naturales y Muse

Efektifitas Ampas Tebu Yang Difermentasi Sebagai Media Budidaya Cacing Sutra (Tubifex SP.)

The utilization of bagasse for additional culture medium of sludge worm (Tubifex sp.) was suppossed to examine the effect of the addition of fermented bagasse in the culture medium on the sludge worm biomass. This research used completely randomized design with 5 treatments and 3 replications. The treatments were 100% bagasse (A); 75% bagasse & 25% mud fields (B); 50% bagasse & 50% mud fields (C); 25% bagasse & 75% mud fields (D); and 100% mud fields (E). Data were analyzed using analysis of variance (ANOVA) test and then continued with Least Significant Difference (LSD) test. The result showed that the best treatment was D treatment (25% bagasse fermented and 75% field mud) with the population 167,618 ind/m2 dan biomass 380.94 gr/m2. Water quality of cultured were temperature of 27°C, pH of 6,9-7,2, dissolved oxygen of 3,6-4,7 ppm, and ammonia of 0,06-2,37 ppm

The Quantum Reverse Shannon Theorem based on One-Shot Information Theory

The Quantum Reverse Shannon Theorem states that any quantum channel can be simulated by an unlimited amount of shared entanglement and an amount of classical communication equal to the channel's entanglement assisted classical capacity. In this paper, we provide a new proof of this theorem, which has previously been proved by Bennett, Devetak, Harrow, Shor, and Winter. Our proof has a clear structure being based on two recent information-theoretic results: one-shot Quantum State Merging and the Post-Selection Technique for quantum channels.Comment: 30 pages, 4 figures, published versio
