Identification of candidate anti-obesity targets
No full textOver the past decade, obesity has become a major health issue in the western world, and is very rapidly becoming a concern for eastern countries as well. In the most basic sense, obesity results from an imbalance between energy intake and energy expenditure. However, the complex disease that is obesity arises as a result of the insufficient energy consumption, resulting in adiposity, the increase of triglyceride storage in adipocytes, body weight gain, and an increased risk of obesity co-morbidities. As the prevalence of obesity is expected to increase over the next 20 years, the identification of novel anti-obesity targets has become paramount in the search for an efficacious and compliance-friendly obesity therapy. In an effort to identify and classify potential anti-obesity targets as experimental candidates for obesity therapy, WAT (white adipose tissue) from Hmga2-/-, Lepob.Lepob double knockout mice, Hmga2+/+ mice, Hmga2-/- mice, and Lepob/Lepob mice were run on microarray to determine gene expression profiles for each genotype. Exclusion criteria were added, and a list of 138 adipocyte-specific genes remained. The genes were then characterized through bioinformatics according to 6 parameters: 1) chromosomal location in mouse genome; 2) chromosomal location in human genome; 3) subcellular localization; 4) function; 5) knockout phenotype in mice; 6) obesity-related QTLs in human genome. After characterization, each gene was evaluated in greater detail and filtered to form a list of candidates for experimental analysis to evaluate anti-obesity effectiveness. The list of 138 genes was finally narrowed to 10 genes, 6 of which were present in the top 25 most highly expressed genes in adipocyte-rich WAT. Preliminary experimental analysis reveals diminished weight gain and overall decreased body weight in mice upon peptide inhibition for one gene from the filtered list. While we have only begun evaluating one gene, thus far, the results are encouraging in that the method used to develop and filter such a list of genes is proving to be validated. Further experimental research is required in order to fully validate each potential candidate; however such an approach, to determine solid candidates, appears promising.M.S.Includes bibliographical referencesby Ahmed Hussain RizviIncludes abstrac
High-Q(2) deep inelastic scattering at HERA
No full textHigh-Q(2) NC and CC cross sections as measured at HERA can give information on two distinct areas of current interest. Firstly, supposing that all the electroweak parameters are well known, these cross sections may be used to give information on parton distribution functions (PDFs) in the new kinematic regime at high x and high Q(2). Secondly, supposing that PDFs are well known after evolution in Q(2) from the kinematic regime where they are already measured, these cross sections may be used to give information on electroweak parameters in a process where the exchanged boson is 'spacelike' rather than 'timelike'. WG1 addressed itself to clarifying the limits of our present and possible future knowledge on both these points
How Can We Make Scientific Events More Inclusive? Insights From Q&A Sessions and Surveys From an International Conference
No full textChen R, Rizvi T, Berthelsen AL, et al. How Can We Make Scientific Events More Inclusive? Insights From Q&A Sessions and Surveys From an International Conference. Ecology and Evolution. 2025;15(7): e71588.**ABSTRACT**
Despite growing awareness of the importance of researcher diversity, barriers to inclusion and equity persist in science and at academic conferences. As hosts of the 37th International Ethological Congress, “Behaviour 2023”, we studied gender disparities that unfold during question‐and‐answer (Q&A) sessions using observational and experimental behavioural data and surveys. We further used the surveys to investigate broader equity, diversity and inclusivity (EDI) issues at conferences in general. Attendees perceived as women asked fewer questions than those perceived as men because they raised their hands less often to ask questions, and not because they were chosen less often by the session host. Self‐reports indicated that self‐identified women felt more comfortable asking questions when their own gender was represented (in the audience, by the speaker, and/or by the host) and when the setting was smaller. However, this pattern was not reflected in the observational data as perceived women asked fewer questions regardless of the situation. We report potential reasons why women asked fewer questions using survey data, and experimentally tested whether we could reduce gender disparity in question‐asking. Our results indicate that session hosts cannot mitigate the gender disparity in question‐asking by actively selecting perceived women to start the Q&A session. We addressed further inclusivity barriers of underrepresented minorities beyond gender in a post‐congress survey, which showed that underrepresented minorities did not have a more positive or negative congress experience but did perceive EDI issues as more severe. We conclude by providing recommendations for organising more inclusive scientific events
Energy Conservation of Cooperative Communication over Composite Channels
No full textThe studies about the effects of multipath fading and shadowing for wireless cooperative networks are insufficient. Almost all real wireless networks can be modeled by changing the parameters of the composite distribution which models both multipath and shadow fading. This composite distribution makes the analytical calculation of bit error rate (BER) difficult. In this thesis report, an approximation for this composite distribution has been introduced. A cooperative method, based on decode and forward (DF) for forwarding, is studied. For a required BER, for instance 10?2, the gain in terms of power with using the cooperation with one relay is 4 dB in comparison to a case with same amount of energy to send a same message for a non cooperative network. The impact of parameters of composite distribution on the gain of cooperative communications (CC) in terms of power is discussed. In this work, the optimum value for power allocation in the relay and sender for a cooperative network is found in the simulations. The different position of a relay in a parallel line with respect to the line of sight (LOS) of the sender and the receiver; and its impact on the BER is investigated. The random deployment of the relays in the network is also investigated.Masters in Electrical EngineeringDepartment of Telecommunication, Wireless and Mobile Communications (WMC) GroupElectrical Engineering, Mathematics and Computer Scienc
Impact of RF Imperfections on 60 GHz Wireless Communication Systems
No full textOver the last couple of decades, wireless communication has proved to be a phenomenal success and has generated a booming industry with over 5 billion mobile handsets in use worldwide. This has on one end eased the life of its users while on the other end has introduced new challenges for wireless system designers. The varying nature of the wireless communication channel results in large differences in the instantaneous received signal strength. Since most mobile terminals are battery powered and operate in a network, simply increasing the transmission power is not an attractive solution, as it reduces the battery life and increases interference. Thus a major challenge in wireless communication is to increase the communication rate and link reliability by utilizing low power, low cost and spectrally efficient systems. Even with the advent of efficient signal processing techniques and miniaturized low power signal processing hardware, the physical bottleneck still remains the available system bandwidth. This has led to the introduction of the 60 GHz band as an attractive alternative. Among other benefits, the 60 GHz band is unlicensed and can provide system bandwidths up to 7 GHz, which is ideally suited for short range indoor wireless services such as wireless local area networks. There are, however, certain challenges that need to be overcome before full potential of 60 GHz band can be harnessed. These challenges include the design of hardware components such as antennas, amplifier and mixers, identification and utilization of suitable base band processing algorithms and efficient communication protocols for wireless networks operating in the 60 GHz domain. This dissertation deals with the design and development of baseband processing techniques for communication devices operating at a carrier frequency around 60 GHz. Firstly, two practical candidates for baseband implementation are identified. The performance of these two alternatives namely single-carrier and multi-carrier is analyzed under various radio frequency circuit imperfections such as phase noise and amplifier non-linearity because low cost radio frequency circuits operating in the 60 GHz band are expected to have less than ideal performance. For both schemes, the performance degradation in terms of operating parameters such as the required number of bits in digital-to-analog converter/analog-to-digital converter and input back-off requirements for the power amplifier as a function of bit error probability, is determined. It is shown that the single-carrier schemes suffer a lower degradation in system performance for a given set of circuit parameters. The single-carrier scheme is therefore, identified as a suitable candidate for 60 GHz baseband implementation. Secondly, we investigate the possibility of using low cost and complexity RF level diversity combining schemes to boost the system performance. Three low complexity diversity combining schemes namely equal gain combining, selection combining and switched combining are considered. An analytical framework for system performance evaluation of different diversity combining schemes by using low complexity RF level quantized phase combining is developed. Analytical expressions for the bit and symbol error rate of multi-level phase shift keying modulated symbols over Rayleigh fading channels are derived. The derived expressions are then utilized to compare the performance with non-coherent schemes under diversity reception. It is shown that the number of quantization levels required to achieve near ideal performance are dependent on the number of the receive antennas and the modulation level. The analysis is also utilized to investigate the impact of phase quantization on the switching threshold for switched combining schemes. It is shown that the switching threshold is not severely affected by phase quantization. The ability to perform various system level trade-offs is also demonstrated. Lastly, a low cost audio demonstrator is proposed. The acoustic channels investigated in this thesis are seen to provide a multi-path rich environment typical of 60 GHz channels. This offers a practical way of verifying the performance of various baseband processing algorithms in a cost effective manner.TelecommunicatieElectrical Engineering, Mathematics and Computer Scienc
