Including the effects of the O(& 1 GeV) masses of the charm quark, τ lepton and target nucleon in DIS phenomenology is discussed with applications to CC neutrino DIS: Neutrino data for F2 are revisited within the global analysis framework. A fully differential calculation refines the CC charm production process as a gate to extract {s(x), s̄(x)}. New results are presented for a ”heavy quark” ver...

Any rational pricing phenomenon in the cross section of equity returns must also show up in the corresponding corporate bond returns. We use this powerful insight to investigate whether the equity and corporate bond markets are integrated with respect to risk premia associated with anomalies. We find that the two markets are not integrated through factors suggested by structural credit risk mod...

This paper details our work towards designing a system for crowd-sourcing responses on thermal comfort in naturally ventilated office buildings. We provide preliminary qualitative findings on the deployment of this system. Specifically, we explore the different human factors that led to our system being used as something akin to a digital complaints box and how we intend to adapt and leverage t...

The voting rule considered in this paper belongs to a large class of voting systems, called “range voting” or “utilitarian voting”, where each voter rates each candidate with the help of a given evaluation scale and the winner is the candidate with the highest total score. In approval voting the evaluation scale only consists of two levels: 1 (approval) and 0 (non approval). However non approva...

A brief review of the modern QCD theory of diffractive DIS is given. The recent progress has been remarkably rapid, all the principal predictions from the color dipole approach to diffraction-the (Q 2 +m 2 V) scaling, the pattern of SCHNC, shrinkage of the diffraction cone in hard diffractive DIS, the strong impact of longitudinal gluons in inclusive J/Ψ production at Tevatron-, have been confi...

We consider possible mechanisms for single spin asymmetries in inclusive Deep Inelastic Scattering (DIS) processes with unpolarized leptons and transversely polarized nucleons. Tests for the effects of non-zero intrinsic k⊥, for the properties of spin dependent quark fragmentations and for quark helicity conservation are suggested. Single spin asymmetries in large pT inclusive hadronic reaction...

I review new results on s-channel helicity nonconservation (SCHNC) in diffractive DIS. I discuss how by virtue of unitarity diffractive DIS gives rise to spin structure functions which were believed to vanish at x ≪ 1. These include tensor polarization of sea quarks in the deuteron, strong breaking of the Wandzura-Wilczek relation and demise of the Burkhardt-Cottingham sum rule. The invited tal...

The motto of high energy QCD is the quark helicity conservation which is often believed to entail the s-channel helicity conservation (SCHC) at small x. Here I review the recent work ([ 1, 2, 3, 4, 5], which shows this belief is groundless and there is an extremely rich helicity-flip physics at small x. The backbone of DIS is the Compton scattering (CS) γ μp → γ ∗ ′ ν p , which at small-x can b...

Theobroma cacao (cacao) is cultivated in tropical climates and is exposed to drought stress. The impact of the endophytic fungus Trichoderma hamatum isolate DIS 219b on cacao's response to drought was studied. Colonization by DIS 219b delayed drought-induced changes in stomatal conductance, net photosynthesis, and green fluorescence emissions. The altered expression of 19 expressed sequence tag...
