Automatic Mapping of Physical Urban Problems Using Remotely Sensed Imagery
Nikolaos Lempesis
Jan 01, 2023
While big cities are expected to exercise cost-effective, evidence-based planning, many are under reactive management, facing simultaneous problems and limited resources. This project develops a proof-of-concept workflow for the...

A Framework to Identify Influences of Environmental Legislation on Corporate Green Intellectual Capital, Innovation, and Environmental Performance
The aim of this paper is to examine the Porter hypothesis which defines that environmental regulations, under certain circumstances, could have positive effects on corporate environmental and economic performance. The majority...

Top quark production at the Tevatron at NNLO.
We present results for top quark production at the Tevatron including next-to-nextto-
leading order (NNLO) soft-gluon corrections. We show the stability of the cross section
with respect to kinematics choice and scale when the...

Charged Higgs production with a top quark at the LHC.
Nikolaos Kidonakis
Feb 08, 2010
I discuss charged Higgs production via the process bg ! tH− at the LHC. I
show that the cross section is dominated by soft-gluon corrections and I provide
results for its dependence on the charged Higgs mass and on the scale...

Forecasts combinations for intermittent demand
Intermittent demand is characterised by infrequent demand arrivals, where many periods have zero demand, coupled with varied demand sizes. The dual source of variation renders forecasting for intermittent demand a very...

Nominal rigidities equilibria in a non-Ricardian economy
Nikolaos Kokonas
Dec 01, 2016
I consider a cash-in-advance economy with nominal price rigidities. Nominal interest rates are the cost of liquidity and fiscal policy sets nominal transfers that affect the distribution of wealth. Under a fiscal policy...
Next-to-next-to-leading order soft and virtual corrections for QCD, Higgs and SUSY processes.
Nikolaos Kidonakis
Feb 08, 2010
I review recent advances in the calculation of higher-order soft-gluon corrections for
a variety of QCD, Higgs, and SUSY processes in hadron colliders. A unified approach
and master formulas for next-to-next-to-leading order...

Two loop and N loop eikonal vertex corrections.
Nikolaos Kidonakis
Feb 15, 2010
I present calculations of two-loop vertex corrections with massive and
massless partons in the eikonal approximation. I show that the n-loop
result for the UV poles can be given in terms of the one-loop calculation.

Next-to-next-to-leading order soft gluon corrections in direct photon production.
Previous work on soft-gluon resummation for direct photon production is extended to include additional
subleading logarithmic terms through O(
3s
) and some representative comparisons are made
to experimental results from the...

Covid-19
In a recent article, we introduced two novel mathematical expressions and a deep learning algorithm for characterizing the dynamics of the number of reported infected cases with SARS-CoV-2. Here, we show that such formulae can...
NNLO soft and virtual corrections for electroweak, Higgs, and SUSY processes.
Nikolaos Kidonakis
Feb 15, 2010
I present applications of a master formula for next-to-next-to-leading order
soft and virtual QCD corrections to various electroweak, Higgs, and
supersymmetric processes. They include Drell-Yan and charged Higgs
production...

A Unified approach to NNLO soft and virtual corrections in electroweak, Higgs, QCD, and SUSY processes.
Nikolaos Kidonakis
Feb 15, 2010
I present a unified approach to calculating the next-to-next-to-leading order (NNLO)
soft and virtual QCD corrections to cross sections for electroweak, Higgs, QCD, and
SUSY processes. I derive master formulas that can be used...

A Master formula for NNLO soft and virtual QCD corrections.
Nikolaos Kidonakis
Feb 15, 2010
I present a master formula for the next-to-next-to-leading order (NNLO)
soft and virtual QCD corrections for any process in hadron-hadron and
lepton-hadron colliders. The formula is derived from a unified threshold
resummation...

A note on the unemployment volatility puzzle
Nikolaos Kokonas
Jan 01, 2023
This paper features an economy with frictional labour markets, Nash bargaining, cyclical opportunity cost of employment and demand-determined output. I show that the model generates big responses of unemployment to productivity...

Threshold corrections in bottom and charm quark hadroproduction at next-to-next-to-leading order.
We calculate threshold soft-gluon corrections to total cross sections and transverse momentum
distributions for bottom and charm quark production in fixed-target experiments,
considering both pp and −p interactions. We...

Debt and welfare in economies with land
In a stochastic economy of overlapping generations subject to uninsurable risks, debt can implement Pareto improvements in welfare. This is the case even in the presence of long-lived assets and no short sales.

Aggregation in economies with search frictions
We derive an aggregation result in economies with indivisible labor supply choices and frictional labor markets, obtaining a tractable model of gross worker flows in aggregate labor markets with search frictions. Our result...
