Processed vs unprocessed collection--what's the difference?
A processed collection has gone through several steps to become a cataloged record, thus available to the researching public. Those steps include a thorough vetting of copyright and restrictions, a verbatim transcription or thorough indexing of the interview including time-stamped calibration, the opportunity for the interviewee to review the transcription, the creation of a finding aid that includes important metadata about the collection, the preservation and optimization of audio files, the creation of user-copies, and cataloging. This process requires the efforts of several LSU Libraries staff members and it has been calculated that for every hour of recording, it takes 35-50 hours to fully process. For a detailed breakdown of the stages and fees associated with archiving oral histories, please see The Oral History Budget. All processed collections are found in the catalog record and many are available on the Louisiana Digital Library. An unprocessed collection is one that has not reached the final stage of completion and is not yet ready to be cataloged. Depending on the stage of processing, more or less of the interview will be available to patrons. See below for the availability of unprocessed collections. An unprocessed collection is not in the catalog record nor the Louisiana Digital Library.

What are Special Collections?
Special collections refer to unique materials that provide both primary and secondary sources to people conducting original research. Our collections are special due to their scarcity or rarity, historical value, monetary value, or research value. Archives are collections of original records created throughout the lifespan of a person, family, organization, or business. These materials essentially provide evidence of the activities, events, functions, and/or responsibilities of the creator(s). Archives and special collections differ from libraries in the types of materials collected and the ways in which they are acquired, organized, described, and made publicly accessible. These differences prompt us to create specific policies and procedures to ensure that our collections can continue to be used for decades or even centuries to come.

Assessment of "weak hook" effects on fish catches and sizes in a pelagic longline fishery Free.
Objective We sought to evaluate the effectiveness of "weak hooks" in reducing the bycatch of Bluefin Tuna Thunnus thynnus in the U.S. Gulf of America (also known as Gulf of Mexico) pelagic longline fishery while maintaining catch rates and size distributions of the primary target species, Yellowfin Tuna T. albacares. Methods A total of 416 experimental pelagic longline sets were conducted aboard commercial vessels in the Gulf of America. Two treatments were compared: a 4.00-mm-diameter circle hook (control) and a custom-made 3.65-mm-diameter circle hook (weak), which were deployed in an alternating fashion. Fish catches and sizes were recorded for each hook type, and catch rates and size distributions were compared statistically. A hook straightening metric was paired with fish fork length for 888 control hooks and 863 weak hooks that caught Yellowfin Tuna. Hook time recorders and time depth recorders were used to estimate escape times for animals that bent weak hooks. Results No significant differences were observed in catch rates between hook types for any of the captured species except Bluefin Tuna, whose catch rates were 46% lower on weak hooks. No differences in size frequency distributions were observed for Yellowfin Tuna between hook types, but larger Bluefin Tuna were caught less frequently on weak hooks. Hook gap widening increased with fish size and was over twice as pronounced for weak hooks compared to control hooks. Approximately 50% of escaped animals that bent weak hooks escaped within 5 min. Conclusions Weak hooks effectively reduced the bycatch of large Bluefin Tuna without significantly affecting the catch rates or size distributions of the primary target species or other encountered species. The increased likelihood of hook straightening on weak hooks suggests a mechanism for selective release of larger Bluefin Tuna, and escape data indicate rapid release for many animals. These results support the use of weak hooks as a tool for reducing bycatch of large Bluefin Tuna and promoting more sustainable fisheries. [ABSTRACT FROM AUTHOR]
Cord Blood Exosomal miRNAs from Small-for-Gestational-Age Newborns: Association with Measures of Postnatal Catch-Up Growth and Insulin Resistance.
Small-for-gestational-age (SGA) infants who experience a marked postnatal catch-up, mainly in weight, are at risk for developing metabolic disorders; however, the underlying mechanisms are imprecise. Exosomes and their cargo (including miRNAs) mediate intercellular communication and may contribute to altered crosstalk among tissues. We assessed the miRNA profile in cord blood-derived exosomes from 10 appropriate-for-gestational-age (AGA) and 10 SGA infants by small RNA sequencing; differentially expressed miRNAs with a fold change ≥2.4 were validated by RT-qPCR in 40 AGA and 35 SGA infants and correlated with anthropometric, body composition (DXA) and endocrine–metabolic parameters at 4 and 12 mo. miR-1-3p, miR-133a-3p and miR-206 were down-regulated, whereas miR-372-3p, miR-519d-3p and miR-1299 were up-regulated in SGA infants. The target genes of these miRNAs related to insulin, RAP1, TGF beta and neurotrophin signaling. Receiver operating characteristic analysis disclosed that these miRNAs predicted with accuracy the 0–12 mo changes in body mass index and in total and abdominal fat and lean mass. In conclusion, the exosomal miRNA profile at birth differs between AGA and SGA infants and associates with measures of catch-up growth, insulin resistance and body composition through late infancy. Further follow-up of this population will disclose whether these associations persist into childhood, puberty and adolescence. [ABSTRACT FROM AUTHOR]
Ground testing and calibration of focal plane detector flight model on board the first pathfinder of CATCH
CATCH-1, as the first satellite of Chasing All Transients Constellation Hunters (CATCH) space mission, was successfully launched into its expected orbit on June 22, 2024. The flight model underwent environmental tests before launch, including thermal cycling, thermal vacuum, and mechanical evaluations. The CATCH-1 detector system is equipped with a 4-pixel Silicon Drift Detector (SDD) array. To ensure the reliability and redundancy of the CATCH-1 detector system, two sets of data acquisition systems were independently designed and calibrated. Our focus is on presenting the ground calibration results of CATCH-1, which demonstrate a strong linear correlation between energy and channel. The main data acquisition system achieves an energy resolution of ∼≤∼4μs≤10μs 120 eV@4 keV, while the backup data acquisition system has a slightly lower energy resolution of around 150 eV@4 keV, both meeting the design requirement of ∼≤∼4μs≤10μs 160 eV@4 keV. Additionally, the time resolution is ∼≤∼4μs≤10μs, complying with the design requirement of ∼≤∼4μs≤10μs. The calibration database now includes the ground calibration results of CATCH-1, establishing a dependable basis for future data analysis. The development experience, calibration, and test results of this detector system will also provide a solid foundation for subsequent tasks such as CATCH-2.
