Economic Policy Uncertainty and Long-Run Stock Market Volatility and Correlation

We use Baker, Bloom, and Davis’s (2016) economic policy uncertainty indices in combination with the mixed data sampling (MIDAS) approach to investigate long-run stock market volatility and correlation, primarily for the US and UK. Long-run US–UK stock market correlation depends positively on US economic policy uncertainty shocks. The dependence is asymmetric, with only positive shocks - increasing

Nutrition and colorectal cancer - The role of BMI, sex, biomarkers and dietary index

Colorectal cancer (CRC) is one of the most common forms of cancer. The cause of CRC is multifactorial, and lifestyle factors are thought to be a major contributor to the development of CRC. It can be hypothesised that the association between food intake and the risk of developing CRC depends not only on the food consumed, but what it is consumed in combination with. The associations between food a

Capacitance Measurements in Vertical III-V Nanowire TFETs

By measuring scattering parameters over a wide range of bias points, we study the intrinsic gate capacitance as well as the charge partitioning of vertical nanowire tunnel field-effect transistors (TFETs). The gate-to-drain capacitance Cgd is found to largely dominate the on-state of TFETs, whereas the gate-to-source capacitance Cgs is sufficiently small to be completely dominated by parasitic com

Knowledge shocks diffusion and the resilience of regional inequality

This paper provides a simplified method of exploring the geographical limits of a knowledge shock over the long run. Using a geographically decomposable distance weighed sum of world GDPs by county, differences in differences regression analysis shows that a new university will not only have a positive impact on the local economy, but also on the GDP of nearby counties. Furthermore, challenging th

Returning Chernivtsi to the cultural map of Europe : The Meridian Czernowitz International Poetry Festival

Drawing on tropes, stories, and symbols emanating from lost layers of urban cultural diversity has been an important resource in post-socialist city branding in many cities in Eastern and Central Europe that saw significant ethno-demographic changes in connection with World War II. In Chernivtsi, this is usually framed by narratives emphasizing tolerance, cultural diversity, and Europeanness, noti

First Measurements of Pulse Picking by Resonant Excitation (PPRE) at the MAX IV 3 GeV Storage Ring

At synchrotron light storage rings there is demand for serving high-brilliance users requesting multibunch operation while simultaneously serving timing users who require single-bunch operation. One method to accomplish this is PPRE developed and currently in user operation at BESSYII. In the method, the transverse emittance of one of the bunches in the bunch train is increased by an incoherent beAt synchrotron light storage rings there is demand for serving high-brilliance users requesting multibunch operation while simultaneously serving timing users who require single-bunch operation.

Pseudo-single-bunch mode for a 100 MHz storage ring serving soft X-ray timing experiments

At many storage rings for synchrotron light production there is demand for serving both high-flux and timing users simultaneously. Today this is most commonly achieved by operating inhomogeneous fill patterns, but this is not preferable for rings that employ passive harmonic cavities to damp instabilities and increase Touschek lifetime. For these rings, inhomogeneous fill patterns could severely r

Timing Modes for the MAX IV Storage Rings

MAX IV-laboratoriet är en anläggning med syfte att producerasynkrotronljus till forskning. När laddade partiklar accelereras skickar de ut energi i form av strålning kallad synkrotronljus. Synkrotronljus är intensivt ljus med många olika våglängder och är därför väldigt användbart för att studera strukturer och processer inom många olika fält såsom materialforskning, medicin, geologi och arkeologiThe MAX IV facility includes two storage rings, operated at 1.5 and 3 GeV energy, for the purpose of producing high-brilliance synchrotron radiation for users. The 1.5 GeV ring replaces the previous MAX II and MAX III storage rings as a source of UV and soft X-rays, whereas the 3 GeV ring is optimized for hard X-rays. The 3 GeV ring is the first of a new generation of synchrotron light storagering

Model Predictive Control (MPC) of an Advanced Multi-Cylinder Engine for Transient Operations

The transportation sector is one of the main contributors to greenhouse gas CO2 and emission of toxic gas. In this sector, advanced technologies and innovations to increase engine efficiency is an important research topic. Low-Temperature Combustion (LTC) concepts are effective approaches for high-efficiency engines. Partially Premixed Combustion (PPC) is one type of low-temperature combustion whi

Visual configuration of two species of Falconidae with different foraging ecologies

Significant interspecific differences in avian vision occur, even in congeneric species, and these have been correlated with differences in the perceptual challenges associated with foraging. Although diurnal raptors are assumed to be mainly visually guided in their foraging, they differ markedly in their foraging tactics and this may result in different visual demands. Among the Falconidae (Falco

From waste to high-value products: Impact of galactoglucomannan purity on selected hydrogel properties

Hydrogels are a hydrophilic network of polymers (usually cross-linked polysaccharides) that are natural or synthetic. Applications of hydrogels are many in the biomedical field. Because of the high water absorption (10 to 200 grams of water per gram of hydrogel), hydrogels have a high degree of flexibility similar to natural human tissue. Human cells can be incorporated into the hydrogel, which in

Techno-economic evaluation for the process optimization of galactoglucomannan and lignin recovery by ultrafiltration

Galactoglucomannans (GGM) can be used as a precursor for the production of surfactants, plastics, hydrogels etc. However, separation of galactoglucomannan (GGM) from lignin and lignin-carbohydrate-complexes using membrane filtration is difficult. Precipitation of GGM with anti-solvents is an approach that has been previously studied. A membrane filtration step prior to precipitation is economicall

Integrated process for sequential extraction of saponins, xylan and cellulose from quinoa stalks (Chenopodium quinoa Willd.)

World quinoa production is increasing due its high nutritional value. As a consequence, large quantities of stalks accumulate as unused byproducts. Here, we verify the presence of saponins in the stalks and present a biorefinery approach with quinoa stalks as feedstock, using an integrated processing scheme to separate saponins, xylan and cellulose. Saponins were extracted using pressurized hot wa
