What is common may be as important as what is different: examining the general factor shared by dispositional shame and guilt using bi-factor models
No full textPrevious research on shame and guilt has tended to focus on their unique associations with other variables. It has become commonplace to eliminate the substantial shared variance with shame when examining guilt, and to eliminate shared variance with guilt when examining shame. What previous research has typically not done is to examine the variance shared by shame and guilt. In a series of three studies, we addressed this issue by employing bi-factor models to examine the general factor shared by shame and guilt, and its relationship to several important personality traits and two broad liability factors of psychopathology (i.e., externalizing and internalizing psychopathology). As hypothesized, the general factor shared by shame and guilt was strongly and positively associated with personality traits associated with moral emotions (empathy, agreeableness and conscientiousness), and strongly but inversely associated with both self-reported and informant-reported externalizing psychopathology. The general factor was also associated with self-consciousness, but not with self-criticism, vulnerable narcissism or neuroticism. The implications of these findings are discussed regarding the conceptualization of shame and guilt.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2020-08-01The student, Wenting Mu, accepted the attached license on 2018-04-13 at 09:14.The student, Wenting Mu, submitted this Dissertation for approval on 2018-04-13 at 09:24.This Dissertation was approved for publication on 2018-04-17 at 17:21.DSpace SAF Submission Ingestion Package generated from Vireo submission #12229 on 2018-09-27 at 11:15:30Made available in DSpace on 2018-09-27T16:27:59Z (GMT).

Efficient checkpoint and recovery scheme in a fast in-memory database
No full textThesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2014.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 61-62).Multicore in-memory databases for modern machines can support extraordinarily high transaction rates for online transaction processing workloads. A potential weakness of such databases, however, is recovery from crash failures. We show that techniques for disk-based persistence can be ecient enough to keep up with current systems' huge memory sizes and fast transaction rates, be smart enough to avoid additional contention, and provide fast recovery. This thesis presents SiloR, a persistence system built for a very fast multicore database system called Silo. We show that naive logging and checkpoints make normal-case execution slower, but that careful design of the persistence system allows us to keep up with many workloads without negative impact on runtime performance. We design the checkpoint and logging system to utilize multicore's resources to its fullest extent, both during runtime and during recovery. Parallelism allows the system to recover fast. Experiments show that a large database (~~ 50 GB) can be recovered in under five minutes.by Wenting Zheng.M. Eng
Precipitation of nesquehonite from homogeneous supersaturated solutions
No full textThe homogeneous (unseeded) precipitation of nesquehonite (MgCO(3)center dot 3H(2)O) was studied over the temperature range of 10-40 degrees C. Precipitation was triggered by the supersaturation created by mixing MgCl(2) solution (0.5-1.5 M) with Na(2)CO(3) solution in the same concentration range. The Meissner's method was adopted in the calculation of supersaturations during the MgCl(2)-Na(2)CO(3) reaction to monitor the precipitation. Solids were identified using X-ray diffraction (XRD) analysis and scanning electron microscope (SEM) images. In the temperature range of 10-40 degrees C, MgCO(3)center dot 3H(2)O with needle-like or gel-like morphology was precipitated. It was seen that the length, width and surface smoothness of the particles changed with reaction temperature and supersaturation. The supersaturation (S) was in the range of 1.09-58.68 during titration of Na(2)CO(3) solution. The dimension of the crystals increased with longer addition time (or lower initial concentration of reactant) at the same temperature. Slower addition via titration of 2 h followed by 2 h of equilibration at 40 degrees C proved successful in producing well developed needle-like MgCO(3)center dot 3H(2)O crystals of 30-50 mu m long and 3-6 mu m wide. MgCO(3)center dot 3H(2)O obtained were calcined to produce highly pure magnesium oxide (MgO) at 800 degrees C. The morphology of MgO was similar to that of their corresponding precursors.

Track model for predicting dynamic responses of railroad bridge approaches
No full textThis research study focused on the development of a novel train-track-bridge model that can analytically tackle the difficult problem of a railway track transition zone and effectively simulate the dynamic response of a bridge approach subjected to moving train loads. The scope of the research encompassed statistical field data analysis, analytical model derivation, algorithmic developments, as well as experimental validation for the track model to provide improved design and maintenance practices. The objective was to better understand governing mechanisms of bridge approach problems that occur near bridge abutments using a field validated train-track-bridge model, study problems associated with differential settlement, hanging ties, impact loads and various lack of support conditions, select mitigation methods for existing deficiencies, and as a result, formulate improved bridge approach designs. The first task in this PhD study involved identification of problematic track bridge approach locations that experienced recurring differential movements for field instrumentation, performance monitoring, and conducting field data collection and interpretation along the US Amtrak Northeast Corridor lines near Chester, Pennsylvania. Multidepth Deflectometers (MDDs) were installed at the selected bridge approaches to monitor individual layer deformations of track substructure layers. Besides MDDs, strain gauges were also mounted on the rail at the instrumented sites to measure vertical wheel loads applied during the passage of a train. Statistical analyses were conducted on the collected field data to quantify track transient response and performance trends at the studied bridge approaches. Field collected data indicated one significant problem occurring at the instrumented bridge approaches, also known as the “hanging crosstie” problem, which is caused by several sequential crossties near the bridge abutment experiencing lack-of-support. These crossties with gaps formed underneath undergo oscillatory motion as the dynamic loading from moving wheels push and pull these crossties through rail deformations. As a result, the nonuniform support conditions of the track substructure worsen drastically and can result in extremely high deformations including heave condition due to train passage.
This dissertation developed a ballasted train-track-bridge model and an analytical solution scheme for both open track (regular track) and near bridge (with severe “hanging crosstie” problem) locations. The simulation results from the developed ballasted train-track-bridge model matched well with the deformation data collected from the field instrumentation to properly validate the analytical solution scheme. Then, using the field validated track model, various mitigation methods, including changing rail pad stiffness, ballast stiffness, subgrade stiffness, and crosstie spacing, applicable to track bridge approaches were studied and discussed. Furthermore, details on two successfully applied mitigation methods, namely, (i) converting an open deck bridge to ballasted deck bridge and (ii) installation of a new track panel consisting of approximately 30 concrete ties with Under Tie Pads (UTPs) at a bridge entrance on Amtrak’s Northeast Corridor high speed passenger lines, were presented.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2022-08-01The student, Wenting Hou, accepted the attached license on 2020-06-08 at 13:37.The student, Wenting Hou, submitted this Dissertation for approval on 2020-06-08 at 13:56.This Dissertation was approved for publication on 2020-06-11 at 11:14.DSpace SAF Submission Ingestion Package generated from Vireo submission #15439 on 2020-10-02 at 15:49:14Made available in DSpace on 2020-10-07T22:48:05Z (GMT).

A study of lipid-mediated clustering of oncogenic Ras proteins on cell membrane using nanotopography engineering
No full textDysregulation of Ras, a dominant oncogenic protein, in cell proliferation, differentiation, and survival contributes to ~20% of human cancers. Despite great efforts paid in identifying anti-Ras therapeutics for the past decades, it remains a challenging task to provide effective anti-Ras drugs for clinical use, with only 1 FDA-approved inhibitor last year over thousands of candidates. To tackle the problem, one promising anti-Ras strategy is to target the lateral segregation of Ras on the plasma membrane (PM) that partitions Ras into guanine nucleotide- dependent dimers and higher-order clusters, the localization of which ensures the fidelity of isoform-specific signaling. Recently, membrane curvature has been identified to be a key membrane property to regulate Ras recruitment and nanoclustering by coordinating with lipids and Ras binding partners. However, due to the limited techniques to manipulate the curvature of the PM effectively, the live-cell characterization of the curvature effect on Ras clustering remains elusive.
Here, a nanotopography-based approach to generate nanoscale membrane curvature for the direct visualization of Ras clustering changes in live cells was established. Using vertically aligned nanobar arrays, Ras clusters were guided into quantifiable patterns along the contour of the nanobars. Enriching Ras clusters at the curved nanobar ends validates that membrane curvature acts as a common modulator of Ras sorting on the PM regardless of Ras isoforms. Within the Ras structure itself, the lipidated membrane anchors of Ras at the C-terminus were shown to be the dominant region causing the curvature-guided Ras clustering. Furthermore, the lipidation-based modification of the palmitoyl tail at Cysteine 181 instead of at Cysteine 184 was found to be essential in H-Ras curvature sensing. Beyond Ras, the nanotopography further demonstrated its capability in reorganizing the membrane microenvironment to mediate curvature-guided Ras clustering. Various lipid species were found to be accumulated to the curved membranes, including phosphatidylinositol 4,5-bisphosphate (PIP2), cholesterol, phosphatidylserine (PS), and phosphatidic acid (PA). Specifically, PIP2 depletion abolished the curvature sensing behaviors of H-Ras and tK. Together, these results suggest lipids to be a key coregulator of Ras curvature sensing. Overall, with the help of surface nanotopography, membrane curvature was validated as a significant modulator of Ras spatial localizations through lipidation-based membrane anchoring and reorganizing the local lipid microenvironment in live cells.It can be envisioned that the nanotopography-induced membrane curvature provides a promising venue for the fundamental investigations and the drug development related to Ras clustering.Doctor of Philosoph
