Coannihilation Scenarios and Particle Spectroscopy in SU(4)_c x SU(2)_L x SU(2)_R
, 2009 We identify a variety of coannihilation scenarios in a supersymmetric SU(4)_c x SU(2)_L x SU(2)_R model with discrete left-right symmetry. Non-universal gaugino masses, compatible with the gauge symmetry, play an essential role in realizing gluino and ...

Supersymmetric Inflation With Constraints on Superheavy Neutrino Masses [PDF]
, 1996 We consider a supersymmetric model of inflation in which the primordial density fluctuations are nearly scale invariant (the spectral index n is approximately 0.98) with amplitude proportional to (M/M_{Planck})^2, where M ~ 10^{16} GeV denotes the scale ...

From dilemmas to paradoxes: A complex systems view of sustainability management in UK universities
European Management Review, EarlyView.Abstract Recently, universities have transformed from passive contributors to active participants in the global sustainability movement. However, the absence of robust theoretical frameworks and larger‐scale samples has limited the progress that universities can make towards becoming sustainable.

From New to Large Field Inflation: Comparison with WMAP3
, 2006 We briefly summarize and update a class of inflationary models from the early eighties based on a quartic (Coleman-Weinberg) potential for a gauge singlet scalar (inflaton) field.

Weather‐Induced Positive Sentiment and Insider Trading
European Financial Management, EarlyView.ABSTRACT Exploiting variations in sunshine exposure near insiders' locations, we find that weather‐induced positive sentiment leads to higher insider purchases, albeit with lower performance. Overoptimism induced by abnormally good weather serves as the underlying mechanism. The effect is more pronounced when insiders' purchase decisions are fuelled by

Smooth Hybrid Inflation and Non-Thermal Type II Leptogenesis
, 2012 We consider a smooth hybrid inflation scenario based on a supersymmetric SU(2)_L x SU(2)_R x U(1)_B-L model. The Higgs triplets involved in the model play a key role in inflation as well as in explaining the observed baryon asymmetry of the universe.

Hairy Roadblock: Stem Trichomes Impede Herbivore Movement in a Species and Instar‐Dependent Manner
Journal of Applied Entomology, EarlyView.ABSTRACT Plants have evolved to deploy a vast set of defence mechanisms against insect herbivores, including physical barriers like leaf trichomes with pre and post ingestive effects. Yet, the role of stem trichomes in plant‐herbivore interactions, particularly mobility dynamics, is poorly understood.

Journal of Fish Biology, EarlyView.Abstract A specimen of rosy barb Pethia conchonius of 51 mm standard length, encountered in an urban pond in London, is reported. This small cyprinid is native to lakes and streams in subtropical regions of southern Asia and is commonly sold as an ornamental fish.

Ripples in the Pond: Product Portfolio Reconfiguration and Dynamism in the Competitive Environment
Journal of Management Studies, EarlyView.Abstract The management literature often overlooks how firms can alter the competitive landscape without introducing groundbreaking changes or innovations. Applying the awareness, motivation, and capability framework from competitive dynamics, we posit that as a firm intensifies its product portfolio reconfiguration, its rivals become increasingly ...

Hybrid inflation followed by modular inflation
, 2007 Inflationary models with a superheavy scale F-term hybrid inflation followed by an intermediate scale modular inflation are considered. The restrictions on the power spectrum P_R of curvature perturbation and the spectral index n_s from the recent data ...
