Clinical decision support tools (DSTs), powered by Artificial Intelligence (AI), promise to improve clinicians' diagnostic and treatment decision-making. However, no AI model is always correct. DSTs must enable clinicians validate each suggestion, convincing them take the correct suggestions while rejecting its errors. While prior work often tried do so explaining AI's inner workings or performance, we chose a different approach: We investigated how validated other's in practice (often...
Abstract High‐quality single‐crystal AB‐stacked bilayer graphene (AB‐BLG) is highly desired because of its unique electronic properties and potential applications. However, growth still unsatisfactory owing to the coexistence BLG and/or multilayer graphene. Here, high‐quality AB‐BLG single crystals synthesized with size ≈30 µm on liquid Cu by chemical vapor deposition. The morphology uniformity are characterized optical micrographs Raman spectroscopy. crystal quality evaluated transmission...
Professional designers often construct and explore conceptual representations (e.g.: design spaces) to help them reason about complex situations consider potential pitfalls. However, it is challenging, even for professional designers, exhaustively the many pitfalls that might result from activity. We present CausalMapper, a mixed-initiative system, leverages large language model (LLM) causal map representation teach students how relationships between problems solutions. Where creativity...
Problem framing—the process of defining a problem—has been described by many researchers and designers as the crux design process. However, novice struggle with problem framing. To better understand this potential for scaffolding, we conducted two studies. In first study, analyzed 41 statements from an introductory course found that novices often omit key information, like primary stakeholder or obstacles they face. get to reflect on include necessary created tool called ProbLib cues...
Making sense of large unstructured problem spaces is cognitively demanding. Structure can help, but adding structure to a space also takes significant effort. ProbMap novel application for automatically constructing design gallery from text input. Given list statements, extracts and semantically groups the stakeholders construct hierarchical search facets which enables designers more efficiently navigate statements. We contribute feature extraction algorithm using natural language processing...
By making the hohlraum wall more opaque to driver energy, efficiency of X-ray conversion is improved with addition depleted uranium (DU) a gold-only [see T. J. Orzechowski et al., Phys. Rev. Lett., Vol. 77, p. 3545 (1996)]. The National Ignition Facility (NIF) point design for ignition requires DU hohlraum, which manufactured by General Atomics. process creating multiple layers presents manufacturing challenges. To produce these components many steps are required. processes an Au-lined...
Possible designs for future direct- and indirect-drive targets required the National Ignition Facility (NIF) include resorcinol formaldehyde (R/F) foam shells. Depending on experiment type, shell dimensional specifications can range from 1.5- to 3.5-mm diameter with a 100- 200-μm wall. This paper will discuss adjustments modifications of process developed smaller-diameter (˜900-μm) OMEGA-scale R/F shells that were used fabricate these higher-aspect-ratio NIF-scale
Resorcinol formaldehyde (RF) foam shells are needed for direct-drive inertial confinement laser fusion experiments at the University of Rochester OMEGA facility. As previously reported, addition long-chained polymers to fabrication process has improved shell wall uniformity, but this change led a lower yield (from ~40 ~15%) that gas retentive after application glow discharge polymer (GDP) using standard deposition technique. We have by modifying coating conditions GDP overcoating background...
Depleted uranium (DU) hohlraums consist of a sputter-deposited DU layer sandwiched between two layers gold and overcoated with thick electrodeposited layer. Production multilayered system dissimilar materials to tight tolerances requires complex set process steps. Process drift in production resulted increased failures led unacceptably low yields. Characterization this failure mechanism indicated poor adhesion layers. Failure one could be traced the preceding Ultimately, were pretreatment...
Brain training techniques are commonly used to enhance an individuals learning and memory, especially in classroom teaching self-directed contexts. Among a range of techniques, the item-level methods that focus on boosting memory for specific item most well-known widely applied ones. In this work, mechanisms underlying two brain spaced repetition retrieval practice, investigated. Studies have proved learners who trained according schedule prone show better acquisition language science...
Single and double sapphire spheres have been precisely suspended in 300 mg/cm3 RF aerogels without a supporting stalk by modifying parameters such as gelation time stability of the aerogel precursor solution use vacuum holder for sphere placement. A process fabricating single-sphere target was also developed using spider silk support (approximately) 100 times thinner than earlier work on similar targets. Characterization ball placement done radiography. Data from characterization these...
AbstractLithographed wire targets have recently been fabricated for use as backlighter experimental campaigns at the OMEGA laser facility. These experiments required with 10-μm gold wires lithographed onto plastic. A process was developed using lithography to make these via sputter coating and liquid solution removal of resist. One challenges overcome in developing this target depositing so that it would strongly adhere The quality much better than made by other methods, such gluing or...
