By irrigating plants using water labeled with deuterium, xylem velocity and dynamic water distribution can be measured. Information on xylem flow can also be obtained with sap flow meters that are placed around stems and which function using a variety of heat pulse-based methods. Non-invasive ...
Adolescent depression is becoming one of the major public health concerns, because of its increased prevalence and risk of significant functional impairment and suicidality. Clinical depression commonly emerges in adolescence; therefore, the prevention a
During the measurements, the AFM cantilever and the sample were fully immersed in the aqueous ionic solution of interest. The thermal spectrum of the AFM cantilever was used to perform the flexural calibration of the AFM cantilevers. The AFM probes were found to have a flexural spring constant ...
e, Accuracies of decoding transitions to different behaviors versus control epochs using a combination of phase signatures related to individual behaviors in each SVM. Each element of the matrix represents the accuracy (mean of 1,000 cross-validations) in an individual phase bin, labeled according...

microscope. Line plot showing methane production by two strains under different nutrients, substrates, pH, and temperature.DComparison of the levels of functional modules (COGs, KOs, and CAZymes) of the two strains. The right bar charts show the categories of the functional modules in the ...
The activity, expressed in cpm/μl, was measured by using a scintillation counter (Beckman Coulter, Brea, California, USA). The assay was carried out by incubating 3.5 × 104 cpm of 5′-32P-labeled oligoribonucleotide P1 with 250 and 500 ng of each protein in 5 mM MnCl2, 50 mM NaCl...
Bernal bilayer graphene (BLG) offers a highly flexible platform for tuning the band structure, featuring two distinct regimes. One is a tunable band gap induced by large displacement fields. Another is a gapless metallic band occurring at low fields, featuring rich fine structure consisting of four...
Since the development of the first microscope by the pioneer Zacharias Jansen (16th century), Robert Hooke (17th century) and later by Anton van Leeuwenhoek (18th century), it has become evident that biological entities have optical properties. The field of imaging methodologies now focuses on vis...
