Complete solo piano works of Zhou Long
No full textAccess to thesis restricted until 07/2023.Zhou Long is a contemporary composer of Chinese American descent, who
belongs to a generation of Chinese composers that began introducing traditional
Chinese music to western audiences. He gained international recognition after
receiving the 2011 Pulitzer Prize for his opera, Madame White Snake (2011). Very
few performances, recordings, and publications currently exist on Zhou’s piano
music, and this doctoral lecture recital is the first time an artist has performed the
complete collection of Zhou’s solo piano pieces. The pieces include: Mongolian Folk-
Tune Variations, Wu Kui, Pianogongs, and Pianobells. In his piano music, Zhou
makes use of unconventional extended piano techniques, imitates and evokes Chinese
traditional instruments, and likes to make connections with other art genres. Also, the
prominence of percussive elements in Zhou’s music is of a great importance. In this
lecture recital, the author has mainly focused on 1) the background information of
Zhou Long and his solo piano works; 2) the influence of Chinese traditional
instruments, ancient literatures and aesthetic concepts, in addition to folk elements on
his piano music; 3) how the composer combined those elements with western music
and compositional skills; and 4) the exploration of the percussive usage of the piano
along with various sound effect. Much of the discussion were from the author’s own
observations; it also include insights from an interview the author conducted with the
composer. Through the combined presentation of the lecture and performance of Zhou
Long’s four piano pieces, the author intended to help bring exposure to his piano
works, and to serve as a guide for piano students and teachers interested in exploring
Zhou’s piano music.Thesis (D.A.

Application of particle swarm optimization in adaptive self-interference cancellation
No full textThis thesis investigates the application of particle swarm optimization in self-interference cancellation. To achieve cancellation, the receiver has to differentiate between the transmit and receive signal. The transmit signal is already known at the transmitting side but it undergoes some distortion before it reaches the receiving end. An adaptive filter proves to be useful in estimating the distortion, but its weight remains an unknown factor. This thesis uses the particle swarm optimization algorithm to dynamically adjust the weights of the filter.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2022-08-01The student, Jingchao Zhou, accepted the attached license on 2020-07-07 at 14:08.The student, Jingchao Zhou, submitted this Thesis for approval on 2020-07-07 at 14:14.This Thesis was approved for publication on 2020-07-07 at 17:20.DSpace SAF Submission Ingestion Package generated from Vireo submission #15513 on 2020-10-02 at 15:31:36Made available in DSpace on 2020-10-07T22:44:25Z (GMT).

Angiotensin II induces soluble fms-Like tyrosine kinase-1 release via calcineurin signaling pathway in pregnancy
No full textMaternal endothelial dysfunction in preeclampsia is associated with increased soluble fms-like tyrosine kinase-1 (sFlt-1), a circulating antagonist of vascular endothelial growth factor and placental growth factor. Angiotensin II (Ang II) is a potent vasoconstrictor that increases concomitant with sFlt-1 during pregnancy. Therefore, we speculated that Ang II may promote the expression of sFlt-1 in pregnancy. Here we report that infusion of Ang II significantly increases circulating levels of sFlt-1 in pregnant mice, thereby demonstrating that Ang II is a regulator of sFlt-1 secretion in vivo. Furthermore, Ang II stimulated sFlt-1 production in a dose- and time-dependent manner from human villous explants and cultured trophoblasts but not from endothelial cells, suggesting that trophoblasts are the primary source of sFlt-1 during pregnancy. As expected, Ang II-induced sFlt-1 secretion resulted in the inhibition of endothelial cell migration and in vitro tube formation. In vitro and in vivo studies with losartan, small interfering RNA specific for calcineurin and FK506 demonstrated that Ang II-mediated sFlt-1 release was via Ang II type 1 receptor activation and calcineurin signaling, respectively. These findings reveal a previously unrecognized regulatory role for Ang II on sFlt-1 expression in murine and human pregnancy and suggest that elevated sFlt-1 levels in preeclampsia may be caused by a dysregulation of the local renin/angiotensin system
Enhanced lattice boltzmann modelling of axisymmetric flows
No full textAn enhanced axisymmetric Lattice Boltzmann fluid simulation model developed by the second author involves no calculation for velocity gradients and has the feature that all external force terms can simply be added to the model. In this paper, the model is extended and applied to investigate the characteristics of two complex axisymmetric flows for further assessment of its capability. First of all, Taylor-Couette flow for Newtonian and non-Newtonian fluids is considered. The combined effects of the Reynolds number, the radius ratio and the power-law index n on the flow characteristics are analysed for an annular space of finite aspect ratio. Different forced axisymmetric laminar coldflow jets are then taken into account with different values of forcing amplitudes in the jets. The numerical results are compared with existing numerical results and experimental data reported in the literature to demonstrate the accuracy of the model

REALIZING EFFICIENT USE AND CONSERVATION OF LAND UNDER PRIVATE OWNERSHIP: A REBUTMENT TO NOBEL ECONOMICS LAUREATE THEODORE W. SCHULTZ
No full textRebutting Theodore W. Schultz's assertions that small farmers are rational, low income countries saddled with traditional agriculture have not the problem of many farmers leaving agriculture for nonfarm jobs, part-time farming is efficient, and economies of scale have no logical basis and not stood the test of time, this paper presents that in (1) the low income countries still saddled with traditional agriculture, (2) the low income countries developing towards the high income economy, and (3) the high income countries, numerous able-bodied part-time and absent farmers earning higher off-farm income tend to under-utilize or idle small (and often fragmented) farms without selling or leasing them to full-time farmers to achieve economies of scale which do have logical basis and stood the test of empirical findings; and indicates that this is a global problem unresolved under private land ownership in both developing and developed countries. Thus small farmers in so doing are not so rational to the societal and their own fundamental interests. The paper also shows that in Central-Eastern Europe and Central Asia under private land ownership or possession many farmers voluntarily remain in collective land operation which perpetuates the low individual incentives. The paper further analyses the dilemmas the EU has been facing in resolving food overproduction, reducing trade-distorting agricultural subsidies and tariffs, keeping self-sufficiency, retaining small farmers in agriculture while strengthening large farmers, and efficient land use; and the crucial imperfections in the EU enlargement process. The paper thus proposes possible solutions on how to protect private land ownership, while transferring under-utilized land to full-time farmers; prevent the high costs of the traditional land consolidation, but still reaching its aims; keep part-time small farmers in agriculture, meanwhile bolstering full-time large farmers; avoid collective land operation, in the meantime benefiting from collective services; boosting EU enlargement but not adding burdens on the EU; retain non-cereal agriculture on ecologically sensitive land, at the same time improving the environment and precluding food overproduction; reduce trade-distorting agricultural subsidies and high tariffs, whereas making full-time farmers viable and competitive; and promote off-farm activities, for the meantime reinforcing agriculture.Land Economics/Use,
