Heavy Quark Production in Deep-Inelastic Scattering at HERA
We discuss two topics in the production of heavy quarks in deep-inelastic
scattering: the next-to-leading order Monte-Carlo HVQDIS and the
next-to-leading logarithmic resummation of soft gluon effects, including
estimates of next-to-next-to-leading order corrections therefrom.Comment: 10 pages, 10 figures, To appear in Proceedings of Monte Carlo

Jet Structure Studies at LEP and HERA
A summary of some recent studies in jet physics is given. Topics include
leading particle production in light flavor events in e+e- annihilations, an
analytical treatment of gluon and quark jets at the
next-to-next-to-next-to-leading order (3NLO), and various studies performed at
LEP and HERA involving separated gluon and quark jets.Comment: 7 pages including 8 figure
Cochrane acute respiratory infections group's stakeholder engagement project identified systematic review priority areas
Objective: Cochrane acute respiratory infections (ARIs) group conducts systematic reviews of the evidence for treatment and prevention of ARIs. We report the results of a prioritization project, aiming to identify highest priority systematic review topics. Study Design/Setting: The project consisted of two phases. Phase 1 analyzed the gap between existing randomized controlled trials and Cochrane systematic reviews (reported previously). Phase 2 (reported here) consisted of a two-round survey. In round 1, respondents prioritized 68 topics and suggested up to 10 additional topics; in round 2, respondents prioritized top 25 topics from round 1. Results: Respondents included clinicians, researchers, systematic reviewers, allied health, patients, and carers, from 33 different countries. In round 1, 154 respondents identified 20 priority topics, most commonly selecting topics in nonspecific ARIs, influenza, and common cold. Fifty respondents also collectively suggested 134 additional topics. In round 2, 78 respondents prioritized top 25 topics, most commonly in the areas of nonspecific ARIs, pneumonia, and influenza. Conclusion: We generated a list of priority systematic review topics to guide the Cochrane ARI group's systematic review work for the next 24 months. Stakeholder involvement enhanced the transparency of the process and will increase the usability and relevance of the group's work to stakeholders
The triangulation of manifolds
A mostly expository account of old questions about the relationship between
polyhedra and topological manifolds. Topics are old topological results, new
gauge theory results (with speculations about next directions), and history of
the questions.Comment: 26 pages, 2 figures. version 2: spellings corrected, analytic

In Solidarity
This edition of Next Page is a departure from our usual question and answer format with a featured campus reader. Instead, we asked speakers who participated in the College’s recent Student Solidarity Rally (March 1, 2017) to recommend readings that might further our understanding of the topics on which they spoke
Design and operational control of an AGV system
In this paper we first deal with the design and operational control of Automated Guided Vehicle (AGV) systems, starting from the literature on these topics. Three main issues emerge: track layout, the number of AGVs required and operational transportation control. An hierarchical queueing network approach to determine the number of AGVs is decribed. Also basic concepts are presented for the transportation control of both a job-shop and a flow-shop. Next we report on the results of a case study, in which track layout and transportation control are the main issues. Finally we suggest some topics for further research
Extreme Star Formation
Extreme star formation includes star formation in starbursts and regions
forming super star clusters. We survey the current problems in our
understanding of the star formation process in starbursts and super star
clusters - initial mass functions, cluster mass functions, star formation
efficiencies, and radiative feedback into molecular clouds - that are critical
to our understanding of the formation and survival of large star clusters,
topics that will be the drivers of the observations of the next decade.Comment: appeared in "Astrophysics in the Next Decade: JWST and Concurrent
