Gender Asymmetries in Cross‐National Couples
Population and Development Review, 2023 AbstractWe use census microdata for Spain and the United States to examine gender differences in cross‐national heterosexual couples (marriages and cohabitating unions involving natives and immigrant spouses). We examine whether native men and native women in cross‐national couples exhibit similar patterns regarding the country of birth, age, and ...

Synthesis of chiral germanium center enabled by poly-deborylative alkylation and desymmetrization
Nature CommunicationsChiral germanium centers are historically undervalued due to their extremely limited synthetic accessibility. Although germanium shares similar chemical properties with silicon, synthesizing chiral germanium centers proves significantly more challenging.

New efficient ligand for sub-mol % copper-catalyzed C–N cross-coupling reactions running under air
Beilstein Journal of Organic Chemistry, 2012 A new efficient ligand, N,N’’-dimethyldiethylene triamine (DMDETA), has been synthesized and evaluated for sub-mol % copper-catalyzed C–N cross-coupling reactions. The efficiency of the ligand was determined by kinetic methods.

Load-Isolation Wireless Power Transfer With K-Inverter for Multiple-Receiver Applications
IEEE Access, 2018 Disturbances among the receivers caused by irrelevant circuit topology and inductive cross couplings among the receiving coils are particularly problematic aspects of multi-receiver wireless power transfer (WPT) systems.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Synthesis of Cross-Coupled Filters With Frequency-Dependent Couplings [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2017 This paper presents a novel synthesis technique for coupled-resonator filters with frequency-dependent couplings. Unlike the works so far appeared in the literature, the proposed technique is not based on the optimization of a network with assigned topology, but it consists in the explicit synthesis of a folded prototype with frequency-dependent ...
