Estimating a model of dynamic activity generation based on one-day observations: Method and results

The article deals with the requirements and needs for long-term digital preservation in different areas of scholarly work. The concept of long-term digital preservation is introduced by comparing it to digitization and archiving concepts and defined with the emphasis on dynamic activity within a certain time line. The structure of digital preservation is presented with regard to the elements of the activity as understood in Activity Theory. The life-cycle of digitization processes forms the basis of the main processing of preserved data in preservation archival system.The author draws on the differences between humanities and social sciences on one hand and natural and technological science on the other. The empirical data characterizing the needs for digital preservation within different areas of scholarship are presented and show the difference in approaches to long-term digital preservation, as well as differences in selecting the items and implementing the projects of digital preservation. Institutions and organizations can also develop different understanding of preservation requirements for digital documents and other objects.The final part of the paper is devoted to some general problems pertaining to the longterm digital preservation with the emphasis of the responsibility for the whole process of safe-guarding the cultural and scholarly heritage for the re-use of the posterior generations. It is suggested that the longevity of the libraries in comparison with much shorter life-span of private companies strengthens the claim of memory institutions to playing the central role in the long-term digital preservation.

Choroidal Perfusion

Optical coherence tomography angiography (OCTA) is a non-invasive tool for imaging and quantifying the retinal and choroidal perfusion state in vivo. This study aimed to evaluate the acute effects of isometric and dynamic exercise on retinal and choroidal sublayer perfusion using OCTA. A pilot study was conducted on young, healthy participants, each of whom performed a specific isometric exercise on the first day and a dynamic exercise the day after. At baseline and immediately after the exercise, heart rate (HR), mean arterial pressure (MAP), superficial capillary plexus perfusion (SCPP), deep capillary plexus perfusion (DCPP), choriocapillaris perfusion (CCP), Sattlers’s layer perfusion (SLP), and Haller’s layer perfusion (HLP) were recorded. A total of 34 eyes of 34 subjects with a mean age of 32.35 ± 7.87 years were included. HR as well as MAP increased significantly after both types of exercise. Both SCPP and DCPP did not show any significant alteration due to isometric or dynamic exercise. After performing dynamic exercise, CCP, SLP, as well as HLP significantly increased. Changes in MAP correlated significantly with changes in HLP after the dynamic activity. OCTA-based analysis in healthy adults following physical activity demonstrated a constant retinal perfusion, supporting the theory of autoregulatory mechanisms. Dynamic exercise, as opposed to isometric activity, significantly changed choroidal perfusion. OCTA imaging may represent a novel and sensitive tool to expand the diagnostic spectrum in the field of sports medicine.

Shed Light

This article examines early modern learning through Ashkenazic responsa. Beyond explicit evidence from published responsa collections, implicit insights dwell in what these publications lack. These missing features shed light on sixteenth-century scholarly practices. The works’ organizational inconsistencies must be understood in context of learned archives. Such an adjustment offers a corrective to the regnant narrative, which views the introduction of print as a sharp rupture from earlier modes of transmission. This article suggests instead that the culture of printed books coexisted with older approaches, and that print was complemented by more disorderly and unconstrained forms of transmission. Comparing rabbinic “paper-ware” with contemporaneous humanist practices highlights the rabbi's working papers, focusing on a culture's dynamic activity rather than its stable output. This shift in perspective allows us to see rabbinic writings not merely as a collection of books but as a mode of scholarship.

Electric Shocks

The selection of reward-seeking and aversive behaviors is controlled by two distinct D1 and D2 receptor-expressing striatal medium spiny neurons, namely the direct pathway MSNs (dMSNs) and the indirect pathway MSNs (iMSNs), but the dynamic modulation of signaling cascades of dMSNs and iMSNs in behaving animals remains largely elusive. We developed an in vivo methodology to monitor Förster resonance energy transfer (FRET) of the activities of PKA and ERK in either dMSNs or iMSNs by microendoscopy in freely moving mice. PKA and ERK were coordinately but oppositely regulated between dMSNs and iMSNs by rewarding cocaine administration and aversive electric shocks. Notably, the activities of PKA and ERK rapidly shifted when male mice became active or indifferent toward female mice during mating behavior. Importantly, manipulation of PKA cascades by the Designer Receptor recapitulated active and indifferent mating behaviors, indicating a causal linkage of a dynamic activity shift of PKA and ERK between dMSNs and iMSNs in action selection.
