Constraints on Higgs Properties and SUSY Partners in the pMSSM
Direct searches for superpartners and precision measurements of the
properties of the GeV Higgs boson lead to important inter-dependent
constraints on the underlying parameter space of the MSSM. The 19/20-parameter
p(henomenological)MSSM offers a flexible framework for the study of a wide
variety of both Higgs and SUSY phenomena at the LHC and elsewhere. Within this
scenario we address the following questions: `What will potentially null
searches for SUSY at the LHC tell us about the possible properties of the Higgs
boson?' and, conversely, `What do precision measurements of the properties of
the Higgs tell us about the possible properties of the various superpartners?'
Clearly the answers to such questions will be functions of both the collision
energy of the LHC as well as the accumulated integrated luminosity. We address
these questions employing several sets of pMSSM models having either neutralino
or gravitino LSPs, making use of the ATLAS SUSY analyses at the 7/8 TeV LHC as
well as planned SUSY and Higgs analyses at the 14 TeV LHC and the ILC. Except
for theoretical uncertainties that remain to be accounted for in the ratios of
SUSY and SM couplings, we demonstrate that Higgs coupling measurements at the
14 TeV LHC, and particularly at the 500 GeV ILC, will be sensitive to regions
of the pMSSM model space that are not accessible to direct SUSY searches.Comment: 23 pages, 9 figures. Contributed to the Community Summer Study 2013,

UVM Tobacco Use and Attitudes After Implementation of a Tobacco-Free Policy
Introduction: Widespread public health initiatives have led to falling smoking rates. Currently, 1,620 U.S. colleges have adopted smoke-free policies. In August 2015, the University of Vermont (UVM) adopted a tobacco-free policy that bans all forms of tobacco use on university property. The purpose of this study was to compare tobacco use and attitudes before and after policy implementation.https://scholarworks.uvm.edu/comphp_gallery/1230/thumbnail.jp
Altered expression of maize PLASTOCHRON1 enhances biomass and seed yield by extending cell division duration
Maize is the highest yielding cereal crop grown worldwide for grain or silage. Here, we show that modulating the expression of the maize PLASTOCHRON1 (ZmPLA1) gene, encoding a cytochrome P450 (CYP78A1), results in increased organ growth, seedling vigour, stover biomass and seed yield. The engineered trait is robust as it improves yield in an inbred as well as in a panel of hybrids, at several locations and over multiple seasons in the field. Transcriptome studies, hormone measurements and the expression of the auxin responsive DR5(rev): mRFPer marker suggest that PLA1 may function through an increase in auxin. Detailed analysis of growth over time demonstrates that PLA1 stimulates the duration of leaf elongation by maintaining dividing cells in a proliferative, undifferentiated state for a longer period of time. The prolonged duration of growth also compensates for growth rate reduction caused by abiotic stresses
Dark Matter in the Coming Decade: Complementary Paths to Discovery and Beyond
In this report we summarize the many dark matter searches currently being
pursued through four complementary approaches: direct detection, indirect
detection, collider experiments, and astrophysical probes. The essential
features of broad classes of experiments are described, each with their own
strengths and weaknesses. The complementarity of the different dark matter
searches is discussed qualitatively and illustrated quantitatively in two
simple theoretical frameworks. Our primary conclusion is that the diversity of
possible dark matter candidates requires a balanced program drawing from all
four approaches.Comment: Report prepared for the Community Summer Study (Snowmass) 2013, on

STEAM Approaches Handbook
For those unfamiliar with the term, STEAM is an acronym for Sciences, Technology, Engineering, Arts and Mathematics. For the STEAM.INC project, Arts encompasses artistic, cultural and creative practices, including design. Also the Sciences includes, not only the traditional natural sciences, but also more contemporary topics such as social and environmental sciences.
This handbook addresses points of intersection across current European Higher Education STEAM approaches and presents a collaborative definition of how STEAM applies in Higher Education. For the project partnership, STEAM in Higher Education includes the customary teaching and curriculum as well as academic research. It also incorporates internal Higher Education policies and governance as well as external engagement with stakeholders and the public. These often become mutually supportive. For example, a university that embraces STEAM, is likely to embed the concept in its curriculum, support STEAM research and innovation and adjust its policies and facilities accordingly.
This publication presents a collection of STEAM approaches as well as the themes and intersections that link them. The handbook shows some of the many different expressions of STEAM from individual, institutional and national perspectives. It aims to provide a shared understanding of what might be achieved by STEAM in Higher Education through identifying foundational competencies and perspectives as well as establishing a baseline of STEAM knowledge.
The project draws a distinction between a ‘STEAM approach’ and a ‘STEAM method’. In general, the former can be considered the wider expression, covering strategies, programmes, fields, and philosophies, whereas the latter more clearly relates to specific techniques. Therefore, this handbook’s perspective is that STEAM methods sit within STEAM approaches.
This is the first comprehensive attempt to collect and codify European approaches to STEAM in Higher Education and, as such, the work is exploratory and should not be considered exhaustive. The handbook is intended to stimulate dialogue about the perceived nature of STEAM, its principles and parameters while providing inspiration for those looking to develop and introduce STEAM approaches of their own
