We have measured the mass of metals in the molecular gas in 13 submillimetre
galaxies at z~4 in which the gas, based on previous observations, lies in a
cold rotating disk. We measured the metal masses using either the submillimetre
line or...

Many planning and decision activities in logistics and supply chain
management are based on forecasts of multiple time dependent factors.
Therefore, the quality of planning depends on the quality of the forecasts. We
compare various forecas...

Quantum Physics
Matter-wave jets are ejected from a Bose-Einstein condensate subjected to a
modulation of the interaction strength. For sufficiently strong modulation
additional higher harmonic matter-wave jets emerge. Here we report the first
experimental...

In recent years, the Generalised Quasilinear (GQL) approximation has been
developed and its efficacy tested against purely quasilinear (QL)
approximations. GQL systematically interpolates between QL and fully non-linear
dynamics by employin...

Spectroscopy detected in the time domain entails many techniques, such as
FTIR, pump-probe, FT-Raman, and 2DES, and applications, such as molecule
characterization, excited state dynamics studies, or spectra classifications.
Surprisingly, a...
Homological mirror symmetry for complete intersections in algebraic tori

We prove one direction of homological mirror symmetry for complete
intersections in algebraic tori, in all dimensions. The mirror geometry is not
a space but a LG model, i.e. a pair given by a space and a regular function. We
show that the ...

Mathematics
Commutative Algebra
Let K be a field, V a finite dimensional K-vector space and E the
exterior algebra of V. We analyze iterated mapping cone over E. If I is a
monomial ideal of E with linear quotients, we show that the mapping cone
constructio...

Label distribution learning (LDL) is an effective method to predict the label
description degree (a.k.a. label distribution) of a sample. However, annotating
label distribution (LD) for training samples is extremely costly. So recent

the exception. However, literature suggests that the longer a questionnaire
takes, the hi...
