Lungfish‐like antero‐labial tooth addition and amphibian‐like enameloid‐enamel transition in the coronoid of a Devonian stem actinopterygian

Journal of Anatomy, EarlyView.
The tooth patterning logic, which cannot be inferred from surface morphology, is revealed by visualizing buried tooth remnants in 3D. The primary teeth are added labially, initially organized in radial rows, which transition into linear rows where the coronoid becomes slender.

How much are we willing to pay for quality wine? A meta‐analysis and meta‐regression analysis

Journal of Economic Surveys, EarlyView.
Abstract This paper performs a meta‐analysis and a meta‐regression analysis on the price semi‐elasticity of wine quality ratings in the context of estimating hedonic price functions. To do so, we thoroughly search for publications that have estimated hedonic functions in this market, resulting in 223 articles estimating 1595 functions, although not all

Martin Luther's Critique of Supererogation

Journal of Religious Ethics, EarlyView.
ABSTRACT Recent decades have witnessed a surge of philosophical interest in the concept of supererogation. Although Martin Luther figures prominently in the historiography as a critic of supererogation, the particular nature of his critique and its place within his broader moral theology has been underexplored.

Fibers beyond structure: do they contribute to embolism reversal after drought relief in poplar?

New Phytologist, EarlyView.
Summary Short‐term recovery from drought‐induced vessel embolism is an energy‐dependent biological process that requires a water source and solutes, both likely supplied by parenchyma cells. Despite fibers primarily providing structural support, their functional role as a reservoir of unbound water during and after stress remains unclear. In this study,

Engineering Rubisco condensation in chloroplasts to manipulate plant photosynthesis

Plant Biotechnology Journal, EarlyView.
Summary Although Rubisco is the most abundant enzyme globally, it is inefficient for carbon fixation because of its low turnover rate and limited ability to distinguish CO2 and O2, especially under high O2 conditions. To address these limitations, phytoplankton, including cyanobacteria and algae, have evolved CO2‐concentrating mechanisms (CCM) that ...

HB52‐PUT2 Module‐Mediated Polyamine Shoot‐to‐Root Movement Regulates Salt Stress Tolerance in Tomato

Plant, Cell &Environment, EarlyView.
ABSTRACT Soil salinity severely restricts crop quality and yields. Plants have developed various strategies to alleviate salinity stress's negative effects, including polyamine redistribution by polyamine uptake transporters (PUTs). However, the mechanisms by which PUTs alter polyamine translocation processes during salt stress have not been fully ...

Characteristics of Scintillation Counters [PDF]

Proceedings of the Physical Society. Section B, 1952
Experimental studies have been made of the distribution in size of output pulses from a scintillation counter detecting monoenergetic alpha-particles. Separate investigations have been made of contributions to the pulse size spread by the photomultiplier and by the scintillating crystal It is shown that the main effect is due to statistical ...

Thin-Crystal Scintillation Counter

Radiology, 1959
The preoperative detection and identification of many types of lesions such as mediastinal tumors (1) have depended upon the use of the Geiger-Muller counter. The conventional scintillation counter has been generally inapplicable due to its size and weight.

Timing with Scintillation Counters

IEEE Transactions on Nuclear Science, 1981
A minimum time-resolution expression is considered for leading-edge timing in which the rise time T1 of SER and its decay time T2 are inserted. Correlation with the parameters involved in other theories indicates the scintillator contribution to T1, which is shown to be the rms time jitter of the photomultiplier at small thickness of scintillator ...

Filament Scintillation Counter

Review of Scientific Instruments, 1957
As a part of a program to develop a solid scintillation chamber, filaments of plastic scintillator material were prepared and formed into a scintillation counter. The filaments can be prepated in lengths of many feet. Care must be taken to avoid surface crazing. The diameter was chosen between 0.5 and l.0 mm in view of the proposed application.
