The purpose of this study is to compare the different short-term interest rate models, and to identify the better model within multiple countries. We selected three different types of data from the United States, the United Kingdom, and New Zealand. We compare the models with the historical data within these three countries, and figure out whether different countries could have their own best mode
Statistical arbitrage is widely used in the quantitative based trading strategies. In this paper, we mainly use Ornstein-Uhlenbeck (O-U) process model and the GARCH model to estimate the parameters and verify trading signals for the statistical arbitrage. In addition, a new model is created through the combination of O-U model and GARCH model. To estimate the models, HuangXia Bank and Industrial B
Several problems concern about energy are frequently discussed in recent decades, such as the shortage of traditional energy resource, the increase of energy price and the destruction of living environment by energy conversion. To solve these problems, sustainable development of energy become a preferential task all around the world. Under current circumstances, applying energy saving measures and
In today’s society people are influenced by technological developments. Technology changed the consumer’s behavior, but also the way companies evolved over time. Nowadays, technology is accessible for everyone, which leads to fast changing environments with a lot of competition. There are limited studies that focus on teams of new ventures in comparison to the lone entrepreneur. However, there are
Menstruation is a normal body function and a sign of reproductive health. Although it is a fundamental human right for girls and women to have the ability to properly manage their menstruation, it is a long-neglected issue in low-income countries. Pilot studies have provided optimism for the menstrual cup’s potential to improve the quality of life for Ugandan girls and women. Several actors are in
The increasing prevalence of Tick-Borne Encephalitis (TBE) in Sweden is a cause of concern to both individuals and the public health service. The disease is spread via bites from the vector Ixodes ricinus and causes long-term neurological damage in 46% of cases. To date, research in this field has focussed on the relationship between climate and TBE incidence and there is little to no available re
In this thesis, the information loss from the modified Mass-Drop tagging of a Z to qqbar jet is studied for a pp collision at LHC centre-of-mass energies in PYTHIA 8 using FastJet 3. The jet created by the Z has minimum transverse momentum of 200 GeV. This is then searched for subjets via two methods: a Cambridge/Aachen algorithm and a modified Mass-Drop Tagger with different z-cut values. The sub
Social innovation and social entrepreneurship receive rapidly growing attention today, due to the inability of current structures and policies to meet the most pressing social problems facing the world. This has concentrated attention on the significance scaling social impact can have on social change. This thesis adds to the literature on scaling up in social entrepreneurship, where the main focu
Plate-like particles of SBA-15 form from smaller units (primary particles) that aggregate in an oriented manner. In this report we influence this aggregation by adding salt to the ongoing synthesis, generating well-ordered hexagonal p6m structure (SBA-15), with varying particle diameters. The additions, with either NaCl or NaI, were made at a time corresponding to the onset of oriented aggregation
Effects of land use changes are starting to be included in estimates of life-cycle greenhouse gas (GHG) emissions, so-called carbon footprints (CFs), from food production. Their omission can lead to serious underestimates, particularly for meat. Here we estimate emissions from the conversion of forest to pasture in the Legal Amazon Region (LAR) of Brazil and present a model to distribute the emiss
The degradation of live plant biomass in fungus gardens of leaf-cutting ants is poorly characterised but fundamental for understanding the mutual advantages and efficiency of this obligate nutritional symbiosis. Controversies about the extent to which the garden-symbiont Leucocoprinus gongylophorus degrades cellulose have hampered our understanding of the selection forces that induced large scale
The authors address the dichotomy around 'proximate' and 'distant' learning processes by looking specifically at the characteristics of the knowledge-creation process. By way of suggesting an alternative conceptualization to the well-known tacit-codified knowledge dichotomy, they propose a distinction between 'analytical' and 'synthetic' modes of knowledge creation. Analytical knowledge creation r
Introduction: Patients with Alzheimer's disease (AD) are currently treated with cholinesterase inhibitors, such as galantamine, without actual knowledge of its concentration in plasma. Our objective was to analyse potential relationships between galantamine concentration, galantamine dose, socio-demographic characteristics, body weight, body mass index (BMI), and treatment response. Methods: Eight
This paper describes the history of Swedish medical radiation physics education and gives details of the core curriculum of today’s 5-year specialised medical radiation physicist programme, which fulfils the need to educate clinical physicists with versatile basic knowledge and skills who are well prepared for professional life in all sub-areas of medical radiation physics and radiation protection
This paper investigates the relationship between history and national identity, specifically how “golden ages” in a nation’s past are used for nationalist ends. Using discourse analysis, it examines how two types of popular historical venues, museums and textbooks, present Japan’s Heian period (794-1185) and explores what this reveals about Japanese national identity formation. The Heian era has a
The mystacocarid crustacean Derocheilocaris typica Pennak and Zinn, 1943 lives in sand interstices and is less than one mm long. It is unique among Arthropoda. It has sensory cells in the mandible, which lack cilia. The function as mechano- and/or chemo-receptors has been replaced by dendrites, the sensory cell protrusions carrying cilia. The dendrites swell, flatten, and fill the endite- a medial
Many plants are adapted to an eroded landscape with a large proportion of virgin soil. Open and disturbed soils are today almost only restricted to agricultural fields with high loads of fertilizers. We conducted a pot experiment in order to investigate growth and nutritional constraints of one calcicole species, Anisantha (syn. Bromus) tectorum, and one calcifuge species, Rumex acetosella, in dec
Glioblastoma multiforme (GBM) is the most common and aggressive form of primary brain tumor. In spite of surgical resection, combined radiation therapy and chemotherapy, the mean survival is less than 15 months following diagnosis. Using the established N29 and N32 animal models of glioma, shown to have many similarities with the human tumor, we are able to study and develop therapeutic strategies
Background: Air pollution, mainly from combustion, is one of the leading global health risk factors. A susceptible group is the more than 200 million people worldwide suffering from chronic obstructive pulmonary disease (COPD). There are few data on lung deposition of airborne particles in patients with COPD and none for combustion particles. Objectives: To determine respiratory tract deposition o
High malignancy and early metastasis are hallmarks of melanoma. Here, we report that the transcription factor Snail1 inhibits expression of the tumor suppressor CYLD in melanoma. As a direct consequence of CYLD repression, the protooncogene BCL-3 translocates into the nucleus and activates Cyclin D1 and N-cadherin promoters, resulting in proliferation and invasion of melanoma cells. Rescue of CYLD
