New estimates of the hybrid US Phillips curve

This paper examines the validity of Rudd and Whelan’s (2006) critiques of Gali and Gertler’s (1999) hybrid Phillips curve (HYPC) by re-estimating the HYPC using full information maximum likelihood (FIML). We also estimate HYPC with the constraint that the weights for the sum of forward looking and backward looking expectations should be unity. Our results support Rudd and Whelan’s conclusion that the weight for forward looking expectations is insignificant.New Keynesian Phillips Curve, Price Rigidities, FIML Estimation

The Unsolved Pathogenesis of Idiopathic Ketotic Hypoglycemia:Involvement of the Pyruvate Dehydrogenase Kinase Isoenzyme 4 Gene?

Background and aim Ketotic hypoglycemia (KH) is the most common cause of hypoglycemia in childhood, among non-diabetic children. KH is defined by episodes of hypoglycemia with high ketone levels in plasma and urine, provoked by periods of fasting, often in combination with an intercurrent illness. KH usually begins at 2 or 3 of age and it typically spontaneously remits by the age of 8 or 9. The pathophysiology of KH has not been fully understood. However, studies have suggested that the glycogenolytic and gluconeogenic pathways are intact. Some even postulate that KH is not a true disease but represents the lower tail of the Gaussian distribution of fasting tolerance in children. The hypothesis of this masters project is that polymorphic variations of a gene involved in the glucose homeostasis could be the cause of KH. In this master project, we have a particular interest for the PDK4 (pyruvate dehydrogenase kinase isoenzym 4) gene, located on the chromosome 7. The mitochondrial pyruvate dehydrogenase complex (PDC) catalyses the conversion of pyruvate to acetyl-CoA. Its activity is regulated by the pyruvate dehydrogenase kinases (PDKs), which phosphorylate and inactivate the PDC, and the pyruvate dehydrogenase phosphatases (PDPs), which dephosphorylate and activate the PDC. In the starved state, the PDC is inactivated to maintain glucose levels by conserving substrate for gluconeogenesis. Studies have identified four PDK isoforms: PDK1, PDK2, PDK3 and PDK4. PDK4 is found in heart, skeletal muscle, liver, kidney and the pancreatic islet. All these tissues ar involved in glucose homeostasis: high rates of glucose utilization, glucose production or production of glucoregulatory hormones. The expression of PDK4 is increased in response to starvation. Moreover, studies have shown that blood glucose levels are lower in PDK4 ¯/¯ mice than in wild type, suggesting that PDK4 is important for glucose homeostasis. That is why PDK4 gene has been chosen to be sequenced to look for any polymorphic variations that could be the basis of KH. Methods To study the PDK4 gene, we have collected DNA samples from ten patients with previous episodes of KH. Written informed consent was obtained from all participating individuals. The study has been approved by the ethics committee of the CHUV. We will perform PCR amplification of all 11 exons and sequence the whole open reading frame. Depending on the results, we will have to evaluate possible polymorphisms versus pathogenic changes

THE EVACUATION PROBLEM IN MULTI-STORY BUILDINGS

The pressure from high population density leads to the creation of high-rise structures within urban areas. Consequently, the design of facilities which confront the challenges of emergency evacuation from high-rise buildings become a complex concern. This paper proposes an embedded program which combines a deterministic (GMAFLAD) and stochastic model (M/G/C/C State Dependent Queueing model) into one program, GMAF_MGCC, to solve an evacuation problem. An evacuation problem belongs to Quadratic Assignment Problem (QAP) class which will be formulated as a Quadratic Set Packing model (QSP) including the random flow out of the building and the random pairwise traffic flow among activities. The procedure starts with solving the QSP model to find all potential optimal layouts for the problem. Then, the stochastic model calculates an evacuation time of each solution which is the primary decision variable to figure the best design for the building. Here we also discuss relevant topics to the new program including the computational accuracy and the correlation between a successful rate of solving and problems’ scale. This thesis examines the relationship of independent variables including arrival rate, population and a number of stories with the dependent variable, evacuation time. Finally, the study also analyzes the probability distribution of an evacuation time for a wide range of problem scale

Gross Domestic Product and Foreign Direct Investment: Empirical Evidence from Vietnam

Foreign direct investment contributes to stimulating sustainable economic growth of each country, but economic growth plays an important role in attracting foreign direct investment. The empirical method was employed on a secondary time series data set during the period 2003-2018 to determine the impact of gross domestic product at current prices on foreign direct investment in Vietnam using a linear approach. The empirical results find that the relationship between gross domestic product and foreign direct investment is a positive sign at 1% significant level. Moreover, the study also shows that business freedom index and investment freedom index has a positive effect on foreign direct investment at 5% significant level. Based on the findings, the article recommends that Vietnam continues to seek positive solutions to enhance the economic growth rate, continuation in investment and business liberalization

비-멕스웰 분포함수를 가지는 BF3 방전의 이온 분율 계산

학위논문(석사) -- 서울대학교대학원 : 공과대학 에너지시스템공학부, 2021.8. 정경재.The 0th-dimensional global model of BF3 plasma discharge has been developed in the low-pressure regime to calculate ion species fractions. The simple model considers equations of the particle balance, the charge conservation, and the particle number conservation. Especially, to reflect the nature of non-Maxwellian electron energy distribution in low-pressure discharges, the electrons are divided into two groups and their proportion is adjusted to see the change of ion species fraction. The main purpose of the thesis is considering the change in ion species fraction when including the high-energy electrons group while fixing the low-energy electrons group and the recombination coefficient is not mentioned. The important contribution in the thesis is using the non-Maxwellian electron energy distribution function to calculate the rate constant. Calculations using only low energy electron groups showed remarkably high sensitivity of the ion beam fraction to electron temperature, and the sensitivity could be mitigated by adding the high energy electron ratio. Furthermore, the recombination coefficient and the high-energy electrons fraction values also played the major role in the model. These parameters can be changed to produce the desired ion species fractions in the model.저압 영역대 BF3 플라즈마의 이온 종 비율을 도출하기 위한 글로벌 0차원 계 산 모델을 개발하였다. 본 단순 모델은 입자 평형, 전하량 보존 및 입자 총량 보존을 고려하여 작성되었으며, 그 중 이온종 비율을 계산하기 위해 제일 중 요하게 고려한 요소는 전자 밀도, 유효 전자 온도, 그리고 이온 재결합 계수 이다. 특히, 저압 방전 영역대의 비 맥스웰 분포를 가진 전자의 거동을 반영 하기 위하여, 전자는 크게 두 가지 종으로 구분되어 각각의 비율을 조정하여 이온종이 그 두 종류 전자의 비율에 대해 어떻게 변화하는지 관측하였다. 본 주제의 주 목적은 재결합 계수가 주어지지 않았을 때, 저 에너지 전자 그 룹을 고정시키고 고 에너지 전자 그룹을 포함하여 이온종의 변화를 관측하는 것이다. 그리고 본 주제에 가장 기여도가 큰 부분은 비 맥스웰 분포를 가지는 전자 모델을 이용하여 계수를 구한 것이다. 저 에너지 전자만을 이용한 계산 은 전자 온도가 이온 빔 비율에 높은 감도를 가진다는 것을 알 수 있었으며, 이는 고 에너지 전자를 계산에 추가하여 낮출 수 있었다. 또한, 재결합 계수 가 해당 모델에 큰 영향을 미친다는 것도 확인할 수 있었다. 재결합 계수가 0 에 가까워야 원하는 이온 종의 생산이 가능하다는 것을 알 수 있었는데, 이는 중성 입자들의 상태가 챔버 벽의 경계면과 상호작용할 때 거의 변화하지 않 는다는 것을 의미한다.Chapter 1.

Neutrino interactions with a weak slowly varying electromagnetic field

We derive the effective action for processes involving two neutrinos and two photons at energies much below the electron mass. We discuss several applications in which one or both photons are replaced by external fields. In particular, Cherenkov radiation and neutrino pair production in weak external fields are investigated for massive Dirac neutrinos.Comment: 7 pages, no figure
