Timer options are relatively new exotic options with the feature that they expire as soon as the accumulated realized variance exceeds a predefined level. This construction leads to a random time to maturity instead of having a fixed exercise day. As shown by Bernard an Cui [7], Timer options can be priced by solving a partial differential equation or by time-changing the stock price process and t
Popular Abstract in English Airborne particulate matter is well known because of its adverse impacts on human health and its role in climate processes. In order to understand completely the role of aerosols in atmosphere, their chemical composition is of basic importance. Chemical analysis of aerosols involves broadly two steps, extraction step and detection/quantification of chemical constituentsAirborne particulate matter is well known because of its adverse impacts on human health and its role in climate processes.

In the 20th century, Sweden distinguished itself as one of the most organized and participatory democracies in the world. But in the late 19th century the situation was much the opposite – Sweden had for Western Europe a low degree of suffrage, and low political participation. To explain the turnaround, this paper explores the evolution of a democratic political culture in the final third of the 1
This article argues that, as individuals are already applying for refugee status in the context of disasters and climate change, a robust understanding of why disasters happen and how different groups are affected, combined with a principled methodology for determining such claims, are critical aspects of the anxious scrutiny that each claim should receive. The limitations of the “hazards” paradig
Popular Abstract in English Among the forms of life found in extreme environments (e.g. high temperatures ‘thermo’ and oxygen deficient ‘anaerobe’), the thermoanaerobic bacteria emerge as a highly evolved and interesting subject of study. Bacteria living as microbial mats in decaying plant material possess a great potential not only to degrade complex biomass but also to produce special chemicals.A novel ethanol-producing thermoanaerobe Caloramator boliviensis 45BT (=DSM 22065T, =CCUG 57396T) was isolated from a hot spring of the Bolivian highlands. C. boliviensis possesses the ability to utilize a wide range of substrates and can efficiently convert hexoses and pentoses into ethanol with concomitant production of acetate, carbon dioxide and hydrogen as by-products of fermentation. However
I den offentlege debatten om høgare utdanning er undervisarane påfallande fråverande. Dei sterkaste stemmene tilhøyrar politikarane, studentane, institusjonsleiarane og pedagogane. Når undervisarane melder seg på er det oftast i ein klagesong over høgt arbeidspress, krevjande studentar og mangel på tid og ressursar til forsking. Kvifor oppfattar brorparten av undervisarar i hI den offentlege debatten om høgare utdanning er undervisarane påfallande fråverande.

Background Increased postoperative cardiac troponin (cTn) independently predicts short-term mortality. Previous studies suggest that preoperative cTn also predicts major adverse cardiovascular events (MACE) and mortality after noncardiac surgery. The value of preoperative and perioperative changes in cTn as a prognostic tool for adverse outcomes has been sparsely investigated. Methods and findings
It is important to study the factors affecting estimates of wetness since wetness is crucial in climate change studies. The availability of digital elevation models (DEMs) generated with high resolution data is increasing, and their use is expanding. LIDAR earth elevation data have been used to create several DEMs with different resolutions, using various interpolation parameters, in order to comp
In a community effort to combat sample mislabeling in multi-omic studies, computational solutions received show a wide range of accuracy. The final collaborative product, COSMO, achieves high performance. Applying COSMO to published datasets demonstrates biological impact of the tool.Sample mislabeling or misannotation has been a long-standing problem in scientific research, particularly prevalent in large-scale, multi-omic studies due to the complexity of multi-omic workflows. There exists an urgent need for implementing quality controls to automatically screen for and correct sample mislabels or misannotations in multi-omic studies. Here, we describe a crowdsourced precision
Today’s scientific texts are complex and multimodal. Due to new technology, the number of images is increasing, as is their diversity and complexity. Interaction with complex texts and visualisations becomes a challenge. How can we help readers and learners achieve multimodal literacy?

Background: Acute myeloid leukemia (AML) patients have limited effect from T-cell-based therapies, such as PD-1 and CTLA-4 blockade. However, recent data indicate that AML patients with TP53 mutation have higher immune infiltration and other immunomodulatory therapies could thus potentially be effective. Here, we performed the transcriptional analysis of distinct T-cell subpopulations from TP53-mu
During the last two decades, molecular methods to study mitochondrial DNA sequence variation have become an important part in the studies of avian haemosporidians. Up until recently, these methods have primarily been used for identification of the parasites and for tentative phylogenetic reconstructions, allowing researchers not trained in traditional parasitology to compare data across the globe.
The Arctic is exposed to even faster temperature changes than most other areas on Earth. Constantly increasing temperature will lead to thawing permafrost and changes in the methane (CH4) emissions from wetlands. One of the places exposed to those changes is the Abisko-Stordalen Mire in northern Sweden, where climate and vegetation studies have been conducted since the 1970s. In our study, we anal
Purpose The purpose of this thesis is to study if and how institutional investors have any impact on shareholder value and operating performance on the Swedish market. The tested explanatory variables are institutional investors grouped in different ways depending on their attributes, firm size, board size and board structure, leverage, firm size, share turnover and stock volatility. Theoretical
Business angels play a crucial role in stimulating the growth of early-stage ventures. They are key players in the venture financing market, providing both financial support and experience from their own entrepreneurial experiences. As the entrepreneurial landscape has historically advantaged males, leading to its male-predominance, previous studies raise awareness of how business angels, particul
