Synthesis And Charge Transport Characterization Of 9,9'-Bifluorenylidene-Based Conjugated Molecules For Single-Molecule Conductance, Zach Moughamian, Jahnavi Badiganti, Jinjia Xu

Undergraduate Research Symposium

Molecular electronics explores the use of individual molecules as functional components in nanoscale electronic devices. In this project, fluorenone-based π-conjugated molecules including 9,9'-bifluorenylidene-S and triphenylamine-substituted derivatives were synthesized to investigate structure-property relationships relevant to molecular charge transport. The synthesized compounds were obtained in 13% and 27% yield respectively. ¹H NMR spectroscopy confirms characteristic aromatic resonances in the 7-9 ppm region consistent with the conjugated framework. UV–Vis spectroscopy reveals absorption maxima at 459 nm and 470 nm, indicating extended π-conjugation and donor-acceptor effects. Single-crystal X-ray diffraction confirms the structure of 9,9'-bifluorenylidene-S, which crystallizes in the monoclinic system (space group P2₁/c). In …

Black Mothers' Stress And Harsh Parenting Moderated By Child Age: A Longitudinal Secondary Analysis, Mandiryn M. Diffee, Theresa A. Moore, Hannah White

Undergraduate Research Symposium

Black mothers from lower socioeconomic status experience the highest stress levels in the United States due to structural and societal disadvantage, and one study shows parenting stress for Black mothers increases as children age from 5 to 8 years old. Stress is a well‑established risk factor for maladaptive parenting practices, including harsh parenting, and can influence these behaviors in ways that extend beyond parents’ conscious control. However, no studies have investigated Black mothers’ parenting stress trajectories from toddlerhood to adolescence, nor whether these trajectories relate to harsh parenting. To address this discrepancy, the present study conducted a multilevel analysis using …

Are You In Control? How Timing And Severity Of Trauma Shape Perceived Self-Agency, Kinsey L. Henrichsen, Caleb A. Sanders, Carissa L. Philippi

Undergraduate Research Symposium

Exposure to trauma may alter self-agency, or the sense that one can influence outcomes and exert control over life circumstances. The present study examined whether the timing and severity of traumatic experiences are associated with perceived self-agency across development. Based on prior research, we tested whether trauma occurring earlier in life would be associated with lower self-agency than trauma occurring later, and whether greater trauma severity would be associated with further reductions in perceived control. Participants were 116 trauma-exposed adults (38 male; 78 female) who reported trauma exposure using the Life Stressor Checklist. Trauma variables included age at earliest trauma, …

Enantioselectivity Of The Photochemical Continuous-Flow Isomerization Of Humulones, Gregory M. Giovine, Trevor Smith, Bruce Hamper

Undergraduate Research Symposium

Humulones, the primary natural product present in the historically significant hop flower, represent a largely unexplored candidate for structure-based pharmaceutical design.  Showing promising biological activity as an anti-bacterial and anti-inflammatory agent, humulones are of interest both for their bioactive properties and for their long-established tolerability and natural abundance.  Humulones undergo a characteristic isomerization reaction, where the six-membered substituted phloroglucinol ring contracts to a five-membered ring isohumulone, under a variety of conditions, including those enabled by brewing conditions (thermal, metal-catalyzed) and by exposure to UV light.  Optimization of the photocatalyzed isomerization of n-humulone to n-isohumulone in flow conditions resulted in a …

System For Controlled Debonding Of A Component Using Software Arming And Enclosure Sensing, Alex Pelosi

Defensive Publications Series

A system for controlled debonding can utilize a multi-stage, software-assisted process. For example, a release procedure may be initiated through a software interface, which can arm a subordinate control module and may start a security timer. The system can then utilize one or more integrated sensors to detect an event, such as the physical opening of the device's enclosure. Upon detection, the control module can actuate a circuit to deliver a controlled electrical current to an electrically-releasable adhesive layer, which can weaken its bond. This approach may simplify component removal and can reduce the risk of damage associated with some …

Routing Ml Inference Requests To Specialized Nodes Based On Prefill-Decode Classification, Satish Kondalam, Muninder Sambi, Rohan Grover, Aman Ahuja

Defensive Publications Series

Traditional hardware-based routing for machine learning (ML) inference requests can be inefficient in resource-constrained environments, such as air-gapped or sovereign deployments, potentially leading to system bottlenecks and suboptimal resource utilization. A disclosed technology relates to a system where a gateway component can classify incoming ML inference requests based on their computational profile, for example, as either prefill (dominant) or decode (dominant). The gateway can then route each request to a specialized node within a disaggregated hardware cluster, such as dedicated prefill nodes optimized for computation or decode nodes optimized for memory bandwidth. This application-aware routing method, which may be combined …

Dynamic Forecasting Of Sovereign Wealth Fund Effects On State-Owned Firm Stocks Using Hybrid Arima–Garch Models, Ananta Hagabean Nasution, Teguh Yudo Wicaksono, Donny Oktavian Syah, Randhy Nugroho

BISNIS & BIROKRASI: Jurnal Ilmu Administrasi dan Organisasi

This study examines the forecasting dynamics of Indonesia's Sovereign Wealth Fund, DANANTARA, on the BUMN-20 Index using a hybrid ARIMA-GARCH model. The establishment of DANANTARA in February 2025 generated mixed reactions among capital market participants, with the Indonesian Stock Exchange suspended trading after share prices declined by more than five percent. Using daily time-series data from June 2018 to August 2026, this study employs a hybrid ARIMA(1,1,3)-GARCH(1,1) framework processed through E-Views 12. The results indicate that the BUMN-20 Index is predominantly driven by broader market movements, as evidenced by the highly significant IHSG return coefficient (β =1.237, p < 0.001). In the mean equation, the DANANTARA announcement and launch events do not produce statistically significant shifts in average returns. However, in the variance equation, the announcement significantly elevated conditional volatility (γ = 0.025, p = 0.009), suggesting heightened market uncertainty. The volatility persistence measure (α + β = 0.952) indicates that shocks to the BUMN-20 Index decay slowly, with a half-life of approximately 14 trading days. The forecasting results suggest a gradually declining trajectory for the index, though this does not imply a causal relationship with DANANTARA. These findings contribute to the literature by demonstrating that the primary channel through which a nascent SWF affects domestic equity markets is volatility rather than returns. The policy implications highlight the importance of for transparent governance and consistent communication in mitigating market uncertainty surrounding DANANTARA's operations.
