Do Financial Incentives Affect Fertility? [PDF]

This paper investigates how fertility responds to changes in the price of a marginal child and in household income. We construct a large, individual-level panel data set of married Israeli women during the period 1999–2005 that contains fertility ...

Equivalent outcomes of human oocytes after vitrification or slow freezing with a modified rehydration protocol

Reproductive Biology and Endocrinology
Background According to data from numerous research studies and reviews, the efficiency of the oocyte slow-freezing method is believed to be compromised.

Orientation‐Engineered Insulator‐Metal Transition in Vanadium Dioxide

Advanced Science, EarlyView.
Crystallographic orientation engineering in VO2/TiO2 heterostructures enables tunable insulator‐metal transitions. The high‐Miller‐index (102) orientation breaks in‐plane mirror symmetry, inducing anisotropic transport, while its inclined oxygen channels accelerate protonation kinetics.

Double versus single blastocyst biopsy and vitrification in preimplantation genetic testing (PGT) cycles: protocol for a systematic review and meta-analysis of clinical and neonatal outcomes

Systematic Reviews
Background The number of re-biopsied blastocysts is widely increasing in IVF cycles and concerns regarding retesting, which involves double biopsy and vitrification-warming, have been raised.

BOULE is Essential for the Dynamic Disassembly of Heat Shock Granules in Male Germ Cells

Advanced Science, EarlyView.
BOULE orchestrates stress granule disassembly in germ cells via a two‐pronged mechanism: it promotes G3BP1 ubiquitination by upregulating TRIM27, generating a signal for VCP/FAF2 recruitment, and it maintains G3BP1 and FAF2 protein levels. BOULE deficiency disrupts disassembly complex formation, leading to impaired heat shock granule clearance ...

Fertility Transition in Pakistan: Evidence from Census [PDF]

In the absence of an accurate and complete registration system, efforts were made to estimate the levels of vital statistics through sample surveys. The first such effort was made through the Population Growth Estimation (PGE) project conducted from ...

Giant Magneto‐Optical Effects in Two‐Dimensional Flat‐Band Antiferromagnets

Advanced Science, EarlyView.
RuOCl2${\rm RuOCl}{_2}$, a two‐dimensional antiferromagnet, hosts energy bands with pronounced directional flatness. This study demonstrates that the flat‐band‐induced optical transitions yield strongly anisotropic absorption and a record‐large magneto‐optical Schafer–Hubert effect, alongside exceptional linear dichroism exceeding 50%.

Patterns of lowest-low fertility in Europe [PDF]

In this paper we conduct descriptive aggregate analyses to revisit the relation between low and lowest-low period fertility on the one, and cohort fertility and key fertility-related behaviors---such as leaving the parental home, marriage and female ...
