Two-dimensional covalent organic frameworks are promising low-density porous materials for lightweight thermal management, yet comprehensive thermal conductivity measurements remain scarce. Particularly, direct in-plane thermal conductivity data for large-area, fully suspended covalent organic framework thin films has not been reported previously. This study addresses this gap by measuring in-plane and cross-plane thermal conductivities of two-dimensional covalent organic frameworks with varying pore sizes using laser-based pump-probe techniques. Transient thermal grating spectroscopy revealed a high in-plane thermal conductivity of 1.18 ± 0.21 W/(m⋅K) for a sample with a 1.4 nm pore size, highlighting a notable pore size effect. Cross-plane thermal conductivity measured via frequency-domain thermoreflectance indicated weak thermal anisotropy for samples with larger pores. Grazing-incident wide-angle X-ray scattering provided structural insights and clarified heat conduction mechanisms. These direct in-plane thermal conductivity measurements enhance understanding of thermal transport behaviors in covalent organic frameworks, supporting their development as advanced thermal management materials. The few options available for the measurement of in-plane and cross-plane thermal conductivity of covalent organic frameworks films limit their application for lightweight thermal management. Here, the authors measure both, the in-plane and cross-plane thermal conductivity of two dimensional covalent organic frameworks with different pore sizes using laser-based pump-probe techniques.

Nitric oxide (NO) has been recently implicated as a powerful inhibitor of immune responses during allograft rejection, and some autoimmune and infectious diseases. We previously showed that one potential regulatory effect of NO is inhibition of IFN gamma -stimulated expression of Class II MHC on macrophages. Activation of this gene is mediated by the \"Class II TransActivator\" (CIITA). We now ask whether NO inhibits CIITA and thus the family of genes regulated by CIITA - Class II MHC, Ii, and H-2M. The latter two genes participate in antigen processing and formation of the cell-surface peptide-Class II MHC complex. Murine macrophages - both peritoneal macrophages and the RAW264.7 macrophage line - were stimulated in vitro with IFN gamma . NO production was measured by the Greiss reagent. Transcription of Class II MHC was measured by nuclear run-on assay. mRNA abundance of Class II MHC, Ii, H-2M, and CIITA was measured by Northern blotting and RT-PCR. NO inhibits IFN gamma -induced increases in the abundance and transcription of the Class II MHC Ab gene. The increases in mRNA abundance of CIITA, Ii, and H-2M are also inhibited. As a control, we found that NO did not inhibit LPS-induce increases in TNF alpha mRNA abundance. NO inhibits IFN gamma -induced increases in CIITA, and thus inhibits the CIITA-regulated genes: Class II MHC, Ii, and H-2M. Early during rejection, NO production by macrophages may result after stimulation by IFN gamma produced by CD4+ T cells, and be an effector of allograft damage. High concentrations of NO may then act as a feedback inhibitor which decreases antigen presentation by macrophages and thus decreases CD4 T cell activation.

As libraries continue to evolve to meet growing patron expectations, employees are challenged with ways to search for information, engage students through technology, and manage libraries. This mixed methods research study investigated the individual, departmental, and organizational impacts of an internally administered staff development program within the Purdue University Libraries system designed to assist employees in meeting many of these skills challenges. Data collected through focus groups, anonymous surveys, employee interviews, and organizational archival information spanned a ten month period. Of the 185 employees within the organization, 91 individuals participated in at least one data collection phase of the study. Results of the study revealed that the staff development program had significantly impacted individual employees and the organization as a whole. Limited results were discovered at the departmental level, which was interpreted as a result of a concentrated organizational effort to increase a system-wide perspective among staff. Further, an exploration of the factors beyond training programs and their effectiveness that seemed to contribute in substantive ways to the impact of training was conducted. An individual's motivation to learn and improve oneself despite age, employee classification, or educational status was a significant finding throughout each data collection phase. Finally, information was obtained on barriers of transferability of training to the workplace, as well as the identification of new training courses. Barriers uncovered included communication practices between supervisors, employees, departments/units, and the physically separated nature of the Purdue Libraries system. New programs identified were a need for supervisory training, interpersonal skills, team building, conflict management and customer service skills. Beyond these descriptive results, the study found that training played a significant, if not the only consistent, link in the tangled weave of individual, departmental/unit, organizational, and team performance. It is this crucial finding demonstrates that training serves a crucial role within the organization.

Dense human flow has been a concern for the safety of public events for a long time. Macroscopic pedestrian models, which are mainly based on fluid dynamics, are often used to simulate huge crowds due to their low computational costs (Columbo & Rosini 2005). Similar approaches are used in the field of traffic simulations (Lighthill & Whitham 1955). A combined macroscopic simulation of vehicles and pedestrians is extremely helpful for all-encompassing traffic control. Therefore, we developed a hybrid model that contains networks for vehicular traffic and human flow. This comprehensive model supports concurrent multi-modal simulations of traffic and pedestrians.
