Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte

Journal of Integrative Plant Biology, EarlyView.
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

Interest Rate Pegs and the Reversal Puzzle: On the Role of Anticipation

Journal of Money, Credit and Banking, EarlyView.
Abstract We revisit the reversal puzzle: a counterintuitive contraction of inflation in response to an interest rate peg. We show that its occurrence is intimately related to the degree of agents' anticipation. If agents perfectly anticipate the peg, reversals occur depending on the duration of the peg.

A Mixture Transition Distribution Modeling for Higher‐Order Circular Markov Processes

Journal of Time Series Analysis, EarlyView.
ABSTRACT This study considers the stationary higher‐order Markov process for circular data by employing the mixture transition distribution modeling. The underlying circular transition distribution is based on Wehrly and Johnson's bivariate joint circular models.

A PLETHORA3/7 transcription factor shapes cucumber shoot architecture

New Phytologist, EarlyView.
Summary PLETHORA transcription factors (PLTs) are master regulators of plant development. Loss of shoot meristematic PLTs leads to reduced phyllotactic regularity and robustness in Arabidopsis and increased inflorescence branching in tomato. Whether these factors have similar functions in other species is not known.

Cosine of angle and center of mass of an operator

, 2010
We consider the notion of real center of mass and total center of mass of a bounded linear operator relative to another bounded linear operator and explore their relation with cosine and total cosine of a bounded linear operator acting on a complex ...

Image of mathematics: A case study of two women's early mathematics experiences

School Science and Mathematics, EarlyView.
Abstract People often view mathematics as abstract, cold, and irrelevant to real life, and their school experiences likely influence such views. In this case study, we investigated the mathematics experiences of two women who participated in an afterschool girls‐only STEM club 30 years ago when they were in fifth and sixth grades.

The Impacts of Problem‐Posing Intervention on the Mathematical Proficiency of Undergraduate Developmental Mathematics Students' Developmental Mathematics

School Science and Mathematics, EarlyView.
ABSTRACT This study investigates the impact of problem‐posing on the mathematical proficiency and engagement of 56 Developmental Mathematics (DM) students enrolled in a noncredit college mathematics course. Using a quasi‐experimental design, one of two existing classes was selected as the experimental group and received a 5‐week intervention focused on

Function Art: Linking Mathematics, Technology, and Visual Arts

School Science and Mathematics, EarlyView.
ABSTRACT This study investigated students' understanding of mathematical functions and strategies to create artwork using GeoGebra. It was framed by the principles of constructionism and examined how students use functions in creating artworks. We gathered data from students' artworks using the Algebra view and the Construction Protocol in the GeoGebra

Disarticulations in Naples: Cultural political ecology, the green transition, and labour unrest at a Whirlpool factory

Transactions of the Institute of British Geographers, EarlyView.
Abstract This article develops a cultural political ecology approach to disarticulations and labour unrest. The reference point for analysis is a struggle at a Whirlpool factory in Naples that the company announced would close in 2019, six months after signing an agreement with the Italian government, including a multi‐million investment plan.
