Why we measure period fertility

open access: yes, 2007
Four reasons for measuring period fertility are distinguished: to explain fertility time trends, to anticipate future fertility, to construct theoretical models and to communicate with non-specialist audiences.

Customizable Fabrication of 2D and Conformal Multielectrode Arrays for 3D Printed Organotypic Bioelectronic Interfaces

open access: yesAdvanced Healthcare Materials, EarlyView.
Aerosol jet printing enables rapid, customizable fabrication of flexible, fully gold multi‐electrode arrays (MEAs) for organotypic bioelectronic interfaces. The printed MEAs exhibit stable electrochemical performance, cytocompatibility, and functionality in recording and stimulation, including integration with 3D‐printed constructs.

A diminishing population whose every cohort more than replaces itself [PDF]

open access: yes
We observe that a dynamic population model can have period fertility that is always below replacement and cohort fertility that is always above replacement.

Soil fungal assemblage complexity is dependent on soil fertility and dominated by deterministic processes.

open access: yesNew Phytologist, 2019
In the processes controlling ecosystem fertility, fungi are increasingly acknowledged as key drivers. However, the understanding of the rules of fungal community assembly regarding the effect of soil fertility level is still limited.

Covalent Organic Frameworks for Photocatalysis

open access: yesAdvanced Materials, EarlyView.
This review provides an overview of recent advances in covalent organic frameworks (COFs) for photocatalysis, focusing on sustainable energy applications like water splitting, hydrogen peroxide generation, and CO2 and N2 reduction. It discusses design principles, structure‐function relationships, challenges in COF photocatalysis, and strategies to ...

The Fertility Transition Around the World - 1950-2005 [PDF]

open access: yes
In this paper we analyze the distribution of fertility rates across the world using parametric mixture models. We demonstrate the existence of twin peaks and the division of the world's countries in two distinct components: a high-fertility regime and a ...

Smoke, alcohol and drug addiction and male fertility

open access: yesReproductive Biology and Endocrinology, 2018
In recent decades, the decline in human fertility has become increasingly more worrying: while therapeutic interventions might help, they are vexing for the couple and often burdened with high failure rates and costs.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

open access: yesAdvanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Environmental effects on progesterone profile measures of dairy cow fertility [PDF]

open access: yes, 2006
Environmental effects on fertility measures early in lactation, such as the interval from calving to first luteal activity (CLA), proportion of samples with luteal activity during the first 60 days after calving (PLA) and interval to first ovulatory ...

Systematic review of fertility‐related psychological distress in cancer patients: Informing on an improved model of care

open access: yesPsycho-Oncology, 2018
Cancer patients experience reproductive concerns from diagnosis through to survivorship. However, research has yet to investigate the degree of fertility‐related psychological distress at different treatment time points: diagnosis, treatment, and ...
