1. Diurnal variations in multi-sensor wearable-derived sleep characteristics in morning- and evening-type shift workers under naturalistic conditions 

   Clark, Ian; Stucky, Benjamin; Azza, Yasmine; et al. (2021)

   Chronobiology international

   Consumer-grade, multi-sensor, rest-activity trackers may be powerful tools, to help optimize rest-activity management in shiftwork populations undergoing circadian misalignment. Nevertheless, performance testing of such devices under field conditions is scarce. We previously validated Fitbit Charge 2 against home polysomnography and now evaluated the potential of this device to document differences in rest-activity behavior, including ...

2. Kinetics and Pathways of the Aqueous Photolysis of Pharmaceutical Pollutants: A Versatile Laboratory or Remote Learning Investigation 

   Buth, Jeffrey M.; Ossola, Rachele; Partanen, Sarah B.; et al. (2021)

   Journal of Chemical Education

   In this laboratory experiment, students explore the aquatic photochemical fate of ranitidine and cimetidine, two common pharmaceutical pollutants found in wastewater. It provides an engaging environmental context for students to develop knowledge of reaction kinetics and photochemistry as well as skill in using analytical instrumentation. This versatile experiment consists of two basic modules, three optional advanced modules, and additional ...

3. Structure of the cytoplasmic domain of SctV (SsaV) from the Salmonella SPI-2 injectisome and implications for a pH sensing mechanism 

   Matthews-Palmer, Teige R. S.; Gonzalez-Rodriguez, Nayim; Calcraft, Thomas; et al. (2021)

   JOURNAL OF STRUCTURAL BIOLOGY

   Bacterial type III secretion systems assemble the axial structures of both injectisomes and flagella. Injectisome type III secretion systems subsequently secrete effector proteins through their hollow needle into a host, requiring co-ordination. In the Salmonella enterica serovar Typhimurium SPI-2 injectisome, this switch is triggered by sensing the neutral pH of the host cytoplasm. Central to specificity switching is a nonameric SctV ...

4. Physical modelling of large wood (LW) processes relevant for river management: Perspectives from New Zealand and Switzerland 

   Friedrich, Heide; Ravazzolo, Diego; Ruiz-Villanueva, Virginia; et al. (2021)

   Earth Surface Processes and Landforms

   In the last 30 years, work on large wood (LW) has expanded and matured considerably, and river scientists, managers and practitioners now have a better appreciation of the role of LW in maintaining ecosystems, forming or stabilizing riverine landforms, and interacting with river morphodynamics. We have gained a better understanding of the hazards posed by the recruitment and transport of LW in the river channel and associated infrastructure. ...

5. Deep Learning Based Digital Backpropagation Enabling SNR Gain at Low Complexity 

   Bitachon, Bertold Ian; Ghazisaeidi, Amirhossein; Eppenberger, Marco; et al. (2021)

   NEXT-GENERATION OPTICAL COMMUNICATION: COMPONENTS, SUB-SYSTEMS, AND SYSTEMS X

   A computationally efficient deep learning based digital backpropagation (DL-DBP) algorithm providing a 1.9 dB SNR over a conventional linear compensation (chromatic dispersion compensation algorithm) and a 1 dB gain over a conventional back-propagation algorithm of the same complexity is presented. The algorithm has been tested in a 1200km transmission experiment. Also, if the algorithm is tested against a conventional digital backpropagation ...
