Representation Of Time

This chapter presents a metaphysics-first treatment of time and temporal concepts and language, opposed to all forms of subjectivism about time. It defends phenomenal externalism about time, and also aims to explain away temptations to subjectivism about time. It argues that we cannot explain the distinction between mere sensitivity to time and representation of time in terms of perceptual constancies. Nor can we explain it in terms of mere sensitivity to time that is coordinated with other genuinely representational states and capacities. A different theory of the distinction is developed, labelled representational preservation, which has to do with the preservation and updating of representations over time. An account of three different kinds of present-tense content in experience is developed. The correct characterization of the kinds can explain away some metaphysical illusions about time and the experience of temporal passage.

AbstractIncreasing numbers of COVID-19 patients, continue to experience symptoms months after recovering from mild cases of COVID-19. Amongst these symptoms, several are related to neurological manifestations, including fatigue, anosmia, hypogeusia, headaches and hypoxia. However, the involvement of the autonomic nervous system, expressed by a dysautonomia, which can aggregate all these neurological symptoms has not been prominently reported. Here, we hypothesize that dysautonomia, could occur in secondary COVID-19 infection, also referred to as “long COVID” infection. 39 participants were included from December 2020 to January 2021 for assessment by the Department of physical medicine to enhance their physical capabilities: 12 participants with COVID-19 diagnosis and fatigue, 15 participants with COVID-19 diagnosis without fatigue and 12 control participants without COVID-19 diagnosis and without fatigue. Heart rate variability (HRV) during a change in position is commonly measured to diagnose autonomic dysregulation. In this cohort, to reflect HRV, parasympathetic/sympathetic balance was estimated using the NOL index, a multiparameter artificial intelligence-driven index calculated from extracted physiological signals by the PMD-200 pain monitoring system. Repeated-measures mixed-models testing group effect were performed to analyze NOL index changes over time between groups. A significant NOL index dissociation over time between long COVID-19 participants with fatigue and control participants was observed (p = 0.046). A trend towards significant NOL index dissociation over time was observed between long COVID-19 participants without fatigue and control participants (p = 0.109). No difference over time was observed between the two groups of long COVID-19 participants (p = 0.904). Long COVID-19 participants with fatigue may exhibit a dysautonomia characterized by dysregulation of the HRV, that is reflected by the NOL index measurements, compared to control participants. Dysautonomia may explain the persistent symptoms observed in long COVID-19 patients, such as fatigue and hypoxia. Trial registration: The study was approved by the Foch IRB: IRB00012437 (Approval Number: 20-12-02) on December 16, 2020.

Dominant Frequencies

Ciliary beating frequency in tissue culture from frog palate and isolated lung was optically examined using instrumentation that was adjusted to measure a fraction of the surface area of a single ciliary cell. Consecutive 1-s segments of the analogue signal were fast Fourier transformed (FFT) to obtain a power spectrum. At room temperature, these power spectra changed over time from 1 s to the next. Each spectrum contained several dominant frequencies of similar intensities. Cooling the preparation resulted in a single-peak spectrum that was constant over time. A mathematical model is proposed to simulate these findings. The results and the mathematical model support the hypothesis that ciliary beating frequency fluctuates over short periods of time.

Abstrak Kesenian tradisional memegang peranan dalam pencirian dan menjadi kekhasan suatu daerah. Bagi wilayah administratif yang menjadi cikal bakal suatu kesenian daerah tentu saja tidak sulit untuk menyebut istilah kesenian khas dan menjadi milik daerah tersebut. Lain halnya dengan wilayah administratif yang tidak memiliki kesenian daerah sehingga akan berusaha menciptakan sebuah kesenian untuk dijadikan sebagai kesenian khas bagi daerahnya. Beruntunglah bagi Kabupaten Subang yang menjadi cikal bakal beberapa kesenian yang terlahir dan besar di daerahnya. Tidak hanya sampai disitu, Pelestarian dan pengembangan kesenian tradisional tampak serius dilakukan. Hal tersebut terlihat dari papan nama berbagai kesenian (tradisional) di beberapa ruas jalan dalam wilayah Kabupaten Subang. Seiring berjalannya waktu tampak jelas terlihat adanya perubahan dalam pernak pernik atau tahapan pertunjukan pada beberapa seni pertunjukan tradisional. Kondisi tersebut pada akhirnya mengundang keingintahuan mengenai strategi kolaborasi apa yang membuat seni pertunjukan tradisional masih tetap diminati masyarakat Subang. Penelitian ini dilakukan dengan menggunakan metode deskriptif analisis yang didukung dengan data lintas waktu baik dari sumber sekunder maupun dari pernyataan informan mengenai seni pertunjukan tradisional di Kabupaten Subang. Dari hasil penelitian diperoleh bahwa kolaborasi yang dilakukan meliputi kolaborasi lintas waktu dan lintas ruang yang masih dibatasi oleh seperangkat aturan agar kolaborasi tidak melenceng dari identitas ketradisionalannya.AbstractTraditional arts play a role in the characterization of a region. The Regency of Subang became the pioneer for inventing and creating some traditional arts. They were born and grew in the area, and their preservation and development are seriously taken into consideration. It is evident that some changes occurred over time, for example in the accessories or phase of performances at several traditional performing arts. ThisNaskah Diterima: 28 Februari 2013Naskah Disetujui: 2 April 2013condition makes the author curious about the strategy of collaboration that makes the people of Subang interested in traditional performing art. The author conducted descriptive analytical method supported by cross-time data either from primary or secondary sources.

“Pacharán” is an aniseed liquor-based beverage made with sloe berry ( Prunus spinosa L.) that has been produced in northern Spain. On the other hand, maqui berry ( Aristotelia chilensis) is a common edible berry from Chile, and currently under study because of its multiple beneficial effects on health. The aim of this work was to design a new aniseed liquor-based beverage with maqui berry, as an industrial alternative to a traditional alcoholic product with bioactive berries. The characterization of its composition, compared with the traditional “Pacharán”, and its evolution during maceration (6 and 12 months) showed that the new maqui liquor had significantly-higher anthocyanin retention over time. More studies on the organoleptic properties and bioactivity are underway.

A Au-Si eutectic vacuum packaging process was evaluated using high sensitivity poly-Si Pirani vacuum sensors. Encapsulation of devices was achieved by bonding a silicon cap wafer to a device wafer using a Au-Si eutectic solder at above 390°C in a vacuum bonder. The Au-Si eutectic solder encircled the devices, providing an airtight seal. The Pirani gauges were encapsulated and tested over a period of several months in order to determine base pressures and leak/outgassing rates of the micro-cavities. Packaged devices without getters showed initial pressures from 2 to 12 Torr with initial leak/outgassing rates of −0.073 to 80 Torr/year. Using getters, pressures as low as 5 mTorr have been achieved with leak/outgassing rates of <10 mTorr/year. Trends in pressure over time seem to indicate outgassing (desorption of atoms from inside of the microcavity) as the primary mechanism for pressure change over time.

Abstract Standard Reference Material (SRM) 1849 Infant/Adult Nutritional Formula has been issued by the National Institute of Standards and Technology (NIST) as a replacement for SRM 1846 Infant Formula, issued in 1996. Extraction characteristics of SRM 1846 have changed over time, as have NIST's analytical capabilities. While certified mass fraction values were provided for five constituents in SRM 1846 (four vitamins plus iodine), certified mass fraction values for 43 constituents are provided in SRM 1849 (fatty acids, elements, and vitamins) and reference mass fraction values are provided for an additional 43 constituents including amino acids and nucleotides, making it the most extensively characterized food-matrix SRM available from NIST.

Abstract Our perceptual experiences as of change over time seem to be accompanied by the sense that time flows. The sense of flow is widely regarded as one of the most elusive aspects of temporal experience. In this paper, I develop a novel account of its nature. I give an initial characterization of the sense of flow as the sense that the present changes—in short, as the sense of replacement. Further, I specify the type of account of the sense of replacement to be developed: since the sense that the present changes will be assumed to be grounded in the perceptual representation that the present changes, my focus will be to explain the perceptual representation that the present changes. I develop an account of the synchronic perceptual representation of the present. Finally, I develop an account of the diachronic perceptual representation of the present as changing.
