Event Reconstruction with MarlinReco at the ILC

After an overview of the modular analysis and reconstruction framework Marlin an introduction on the functionality of the Marlin-based reconstruction package MarlinReco is given. This package includes a full set of modules for event reconstruction based on the Particle Flow approach. The status of the software is reviewed and recent results using this software package for event reconstruction are presented.Comment: 6 pages, 2 .eps figures, to appear in Proc.

Cross-cultural medical education: Using narratives to reflect on experience

Introduction. Educating students in a multi-cultural society is a challenge as teachers, students and the community they serve all tend to representvarious social groups. Skills alone are not adequate for competency in understanding cultural aspects of consultations. A combination of knowledge, skills and attitude is the most widely accepted current approach to teaching culturally competent communication to medical students. Collaborative reflection on narratives of experienced clinicians’ cultural encounters served to construct an understanding of how to develop these attributes.Process. An interest group of medical teachers met to address the specific needs of teaching a relevant cross-cultural curriculum. Participants offerednarratives from their professional life and reflected on these encounters to understand how to improve the current curriculum to better address theneeds of the students and patients they serve.Results. Through narratives, participants were able to reflect on how their experience had allowed them to develop cultural awareness. All storiesrepresented how attitudes of respect, curiosity and unconditional positive regard were held above all else. The process of collaborative reflection withpeers unpacked the complexity and potential in the stories and different learning opportunities were discovered. Learning was personalised becausethe stories were based on real experiences.Conclusion. The use of collaborative reflection on narratives of clinical encounters could facilitate insights about cultural aspects of medical practice. Elements such as curiosity, respect and unconditional positive regard are illustrated in a unique way that allows students to appreciate the real-life aspects of cross-cultural clinical encounters

Testing the Higgs Mechanism in the Lepton Sector with multi-TeV e+e- Collisions

Multi-TeV e+e- collisions provide with a large enough sample of Higgs bosons to enable measurements of its suppressed decays. Results of a detailed study of the determination of the muon Yukawa coupling at 3 TeV, based on full detector simulation and event reconstruction, are presented. The muon Yukawa coupling can be determined with a relative accuracy of 0.04 to 0.08 for Higgs bosons masses from 120 GeV to 150 GeV, with an integrated luminosity of 5 inverse-ab. The result is not affected by overlapping two-photon background.Comment: 6 pages, 2 figures, submitted to J Phys G.: Nucl. Phy

Calomplification — the power of generative calorimeter models

Motivated by the high computational costs of classical simulations, machine-learned generative models can be extremely useful in particle physics and elsewhere. They become especially attractive when surrogate models can efficiently learn the underlying distribution, such that a generated sample outperforms a training sample of limited size. This kind of GANplification has been observed for simple Gaussian models. We show the same effect for a physics simulation, specifically photon showers in an electromagnetic calorimeter

(2E)-1-[2-Hydr­oxy-4-(2-methyl­prop­oxy)phen­yl]-3-(4-methyl­phen­yl)prop-2-en-1-one

The benzene rings in the title compound, C20H22O3, form a dihedral angle of 10.39 (8)°. Overall, the mol­ecule is approximately planar with the exception of one of the terminal methyl groups; excluding this group, the r.m.s. deviation for the remaining 22 non-H atoms is 0.0968 Å. The conformation about the C=C bond is E, and an intra­molecular O—H⋯O hydrogen bond leads to the formation of an S(6) motif. In the crystal, linear supra­molecular chains are formed along the a axis via C—H⋯O contacts, and these are connected into double chains via C—H⋯π inter­actions

Beneficial Effects of Insulin on Glycemic Control and β-Cell Function in Newly Diagnosed Type 2 Diabetes With Severe Hyperglycemia After Short-Term Intensive Insulin Therapy

OBJECTIVE—To evaluate whether treatment with insulin is advantageous compared with oral antidiabetes agents in newly diagnosed type 2 diabetes with severe hyperglycemia after short-term intensive insulin therapy

Membranes by the Numbers

Many of the most important processes in cells take place on and across membranes. With the rise of an impressive array of powerful quantitative methods for characterizing these membranes, it is an opportune time to reflect on the structure and function of membranes from the point of view of biological numeracy. To that end, in this article, I review the quantitative parameters that characterize the mechanical, electrical and transport properties of membranes and carry out a number of corresponding order of magnitude estimates that help us understand the values of those parameters.Comment: 27 pages, 12 figure
