Approaching Lower Bound Of Lattice Thermal Conductivity By Simultaneously Suppressing Diagonal And Off-Diagonal Phonon Contributions, Alejandro David Rodriguez, Riccardo Rurali, Changpeng Lin, Joshua Ojih, Mohammed Al-Fahdi, G. Jeffrey Snyder, Ming Hu

Faculty Publications

Pushing the intrinsic lattice thermal conductivity (LTC) in crystalline materials to lower bounds is crucial for fundamental materials research towards emerging technologies including thermoelectric energy conversion and thermal management in both hypersonic aircraft and next-generation turbine systems. However, in the ultralow LTC regime ( <  1 Wm-1K-1), the competition between propagative (particle-like) and coherent phonons—arising from off-diagonal components—poses a significant challenge in further reducing LTC. We perform quantitative analysis of 4700 materials using density functional theory (DFT), spanning all crystallographic groups, to elucidate the interplay between diagonal and off-diagonal phonon contributions. We identify a critical balance between these transport mechanisms, where intermediate phonon lifetimes ( ~ 1 ps) and slow group velocities ( ~ 1 km/s) collectively suppress both contributions, enabling ultralow LTC. Results from a large dataset of 31,058 structures by machine learning models strongly resemble the DFT trends of two-channel phonon transport. Leveraging these models, we screen 25,882 additional materials and confirm their properties with DFT, identifying 12 candidates with ultralow room-temperature LTC—including a record-low value of 0.132 Wm-1K-1. Our large-scale analysis reveals fundamental insights into dual-channel phonon transport, enabling rational design of ultralow LTC materials and accelerating the discovery of advanced phononic crystals with tailored thermal transport properties.

A Holistic Modelling Framework For Functionally Safe Software Architectures In Embedded Control Systems, Thomas Barth

Doctoral

Embedded control systems are integral to most modern electrified products and an essential backbone of ongoing digitalisation [1]. In this context, these systems increasingly perform safety-critical functions where failures can lead to severe personal injury, environmental damage, or significant economic loss [2]. Consequently, they fall more often within the scope of regulation such as IEC 61508 and its derivatives [3]. At the same time, driven by hardware evolution and market demands, embedded control systems continue to grow in both integration density and functional complexity [4]. These demands necessitate structured development methods that balance compliance with cost-efficiency and development agility. A …

Journey To A Heart Safe Community, Mary Mccormack, Carole Zarcone, Kendra Hoepper, Dorothy Veron

Creating Healthy Work Environments (CHWE)

The sudden loss of life is a traumatic event inflicting devastating and lasting impacts on families and communities. It has been estimated that more than 350,000 episodes of out-of-hospital cardiac arrest (OHCA) occur annually in the United States (Virani et al., 2021); however, being that there is no nationwide mandatory reporting system, this number may be a gross underrepresentation of reality. The majority of OHCA occur residential homes and in the community setting. Survival rates are heavily dependent upon provision of immediate cardiopulmonary resuscitation (CPR) and defibrillation with neurologic damage occurring within 5 minutes (Brooks et al., 2022).

Enhancing Risk Governance In Agile Settings: Toward An Integrated Agile Framework For Strategic Risk Alignment, Mohammed Shaik

Harrisburg University Dissertations and Theses

Agile project management is widely used in dynamic and regulated environments because of its adaptability and iterative delivery (Beck et al., 2001). However, Agile teams often rely on informal risk practices that may limit visibility into enterprise-level risks (Stare, 2014). In contrast, Enterprise Risk Management (ERM) frameworks provide structured oversight aligned with strategic objectives (Committee of Sponsoring Organizations of the Treadway Commission [COSO], 2017), yet they are frequently viewed as fast-paced project settings. This misalignment creates governance challenges for organizations operating in complex environments.

This study examined how Agile practices can be integrated with ERM frameworks to strengthen strategic risk …
