Bringing regularized optimal transport to lightspeed: a splitting method adapted for GPUs

We present an efficient algorithm for regularized optimal transport. In contrast to previous methods, we use the Douglas-Rachford splitting technique to develop an efficient solver that can handle a broad class of regularizers. The algorithm has strong global convergence guarantees, low per-iteration cost, and can exploit GPU parallelization, making it considerably faster than the state-of-the-art for many problems. We illustrate its competitiveness in several applications, including domain adaptation and learning of generative models.Comment: 9 pages, 4 figure

Why Swedes Don’t Wear Face Masks During the Pandemic – A Consequence of Blindly Trusting the Government

Government trust is generally helpful for societies, especially in crisis situations, such as during the COVID-19 pandemic, because governments rely on citizens to follow directives. Worldwide, with supporting evidence accumulating, a key directive has been to wear face masks. However, in Sweden, the government has questioned their usefulness. On other behavioral recommendations, such as handwashing, the government has taken a conventional path. We rely on this non-recommendation of face masks to examine the causal impact of government trust on behavior. Based on a large Swedish survey fielded during the pandemic, we find that higher government trust reduces the likelihood of wearing face masks. In contrast, higher trust increases the likelihood of handwashing. The findings qualify the conclusion about the beneficial consequences of trust

Crossover from time-correlated single-electron tunneling to that of Cooper pairs

We have studied charge transport in a one-dimensional chain of small Josephson junctions using a single-electron transistor. We observe a crossover from time-correlated tunneling of single electrons to that of Cooper pairs as a function of both magnetic field and current. At relatively high magnetic field, single-electron transport dominates and the tunneling frequency is given by f=I/e, where I is the current through the chain and e is the electron's charge. As the magnetic field is lowered, the frequency gradually shifts to f=I/2e for I>200 fA, indicating Cooper-pair transport. For the parameters of the measured sample, we expect the Cooper-pair transport to be incoherent.Comment: 5 pages, 4 figures; v2: minor changes, clarifications, addition

Betongpålars miljöpåverkan

The need to perform basic construction reinforcements is growing all the time because in our larger cities they have already built in most places. The untouched land where there is no settlement is due to poor geological conditions. This makes piling more common today, and in the future the usage will grow even more. Concrete is now and has long been one of Sweden's most common construction materials. The material has outstanding traits with a good durability that has made the material valuable in comparison with many others. This report aims to examine and compare the impact of two different types of concrete piles. The reason for this is that environmental issues are becoming increasingly more important in society and the realization that the earth's limited resources clearly shows that humans must take responsibility and act to take care of the environment. The construction sector is today one of the major environmental pressures in society. Today's standard piles consist of cement, reinforcement additives and aggregates of various sizes. The most common concrete pile has a dimension of 275x275 mm. The new fiber pole with dimension 235x235 mm has a halved amount of reinforcement and where steel fiber is added to provide a greater load carrying capacity. This new fiber pole can directly replace a 275x275 mm pole as it has the same load capacity. This leads to a direct reduction of concrete resulting in less material usage and reduced transportations, which means a reduced CO2 emission. The size of the decrease is due to a number of different parameters. The main factors for the decline of the carbon footprint is reduced material consumption due to the fiber pile is of a smaller cross section. The smaller cross section also leads to lower transport emissions upon delivery to the customer when trucks can carry more of the smaller piles. This case study is based on carbon dioxide equivalents to investigate any impact on the climate for the production of concrete. The results show that if one replaces all standard piles for fiber concrete piles for a year in Sweden, The gain is roughly 2600 tons of carbon dioxide that are reduced and is not released into the atmosphere. The results of the report are a direct figure of piles climate impact in terms of greenhouse gas emissions. It should be mentioned that there are other environmental benefits such as reduced emissions of acid gases and a reduced use of gravel
