Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

open access: yesAdvanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Strawberry fertilizer trial: Tests in new strawberry planting on old potassium deficient apricot land indicated no response to potash or phosphate

open access: yesCalifornia Agriculture, 1957
Lassen variety strawberries replacing an Alameda County apricot orchard—pulled because of severe potassium deficiency symptoms—provided an opportunity to work with low potassium strawberries on Dublin clay soil.

Displacive In‐Plane Ferroelectricity with Domain‐Specific Curie Temperature in Van der Waals Semiconductors

open access: yesAdvanced Science, EarlyView.
Temperature‐dependent electron diffraction on tin monochalcogenides demonstrates a gradual displacive transformation between ferroelectric and paraelectric phases with significant variability in lattice constants and Curie temperature (TC). Periodic variations exist even between domains in individual crystals, implying a domain‐specific Curie ...

Current recommendations and standards governing the use of potassium iodide for pregnant and lactating women (clinical lecture)

open access: yesГинекология, 2013
A critical consequence of chronic iodine deficiency during fetal development and early childhood is a violation of intellectual development. The need and the order of iodine prophylaxis in pregnant and lactating women identified the World Health ...

Developmentally Inspired Bioprinting of Nascent Multicellular Human Heart Tissue Through in Situ Differentiation and Morphogenesis of iPSCs

open access: yesAdvanced Science, EarlyView.
A developmentally inspired bioprinting approach enables the fabrication of pluripotent tissues that undergo shape‐morphing and in situ cardiac lineage specification. This method employs embedded bioprinting to deposit iPSCs within soft granular hydrogels to create pluripotent tissue constructs that undergo cell‐mediated shape morphogenesis.

Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants

open access: yesAdvanced Science, EarlyView.
This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...

VDAC1 Upregulation Induces Hyperexcitability of Nociceptive Sensory Neurons Via Enhanced Mitochondrial Atp Efflux in Neuropathic Pain

open access: yesAdvanced Science, EarlyView.
The mechanism diagram of VDAC1 mediating neuronal excitability and neuropathic pain. Briefly, VDAC1 is expressed in DRG neurons and is upregulated following CCI‐induced neuropathic pain. This upregulation enhances ATP transport from mitochondria to the cytoplasm in sensory neurons, leading to increased neuronal excitability and pain behavior.

Need for potassium fertilizer on cotton determined by leaf and soil analyses

open access: yesCalifornia Agriculture, 1960
Fertilizer trials and field studies in 1957, 1958, and 1959 indicated that the soil in some cotton fields in the San Joaquin Valley was deficient in available potassium, and the application of potassium fertilizers significantly increased cotton yields ...
