1. 1. Performance Analysis of Cognitive Radio Networks with Interference Constraints

   Författare :Hung Tran; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio Networks; Spectrum Underlay Access; Interference Constraints; Cognitive Cooperative Radio Networks;

   Sammanfattning : To support the rapidly increasing number of mobile users and mobile multimedia services, and the related demands for bandwidth, wireless communication technology is facing a potentially scarcity of radio spectrum resources. However, spectrum measurement campaigns have shown that the shortage of radio spectrum is due to inefficient usage and inflexible spectrum allocation policies. LÄS MER

3. 2. Acute poisoning in northern Vietnam: epidemiologic, diagnostic and therapeutic aspects

   Författare :Tran Hung Ha; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :acute poisoning;

   Sammanfattning : Poisoning is a major health problem in northern Vietnam. The aims of these studies were to improve prevention, differential diagnosis and treatment of this threat to the public. LÄS MER

4. 3. Counting rational points on genus one curves

   Författare :Manh Hung Tran; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diophantine equations; rational points; Elliptic curves; genus; descent; determinant method; cubic and quartic curves; genus;

   Sammanfattning : This thesis contains two papers dealing with counting problems for curves of genus one. We obtain uniform upper bounds for the number of rational points of bounded height on such curves. The main tools to study these problems are descent and various refined versions of Heath-Brown’s p-adic determinant method. LÄS MER

5. 4. The density of rational points and invariants of genus one curves

   Författare :Manh Hung Tran; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; genus one; discriminant; modular form; Elliptic curve; height; descent; determinantal representation; invariant; rational point; theta function.; determinant method;

   Sammanfattning : The present thesis contains three papers dealing with two arithmetic problems on curves of genus one, which are closely related to elliptic curves. The first problem is to study the density of rational points presented in Papers I and II. LÄS MER

7. 5. Characterizing important flavivirus-host interactions : Replication, assembly, restriction factors and vaccine development

   Författare :Pham Tue Hung Tran; Magnus Johansson; Wessam Melik; Naveed Asghar; Sören Andersson; Laurent Chatel-Chaix; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Flaviviruses; virus-host cell interaction; lunapark; ESCRT; ALIX; CHMP4A; ISG15; TRIMs; replicon virus-like particles; vaccine;

   Sammanfattning : The genus Flavivirus (family Flaviviridae) consists of important zoonotic viruses that cause morbidity and mortality worldwide. These viruses are enveloped and have a positive-sense single-stranded RNA genome encoding a polyprotein. LÄS MER
