On $\ell$-torsion in class groups of number fields

open access: yes, 2017
For each integer $\ell \geq 1$, we prove an unconditional upper bound on the size of the $\ell$-torsion subgroup of the class group, which holds for all but a zero-density set of field extensions of $\mathbb{Q}$ of degree $d$, for any fixed $d \in \{2,3 ...

Fabrication of Superinsulating Poly(Urethane‐Isocyanurate) Aerogels Derived from Upcycled Polycarbonate

open access: yesAdvanced Sustainable Systems, EarlyView.
Bisphenol‐A polycarbonate is upcycled via a simple one‐pot reaction into an aromatic Mannich polyol, which serves as a precursor for fabricating poly(urethane‐isocyanurate) (PUR‐PIR) aerogels. PUR‐PIR aerogels, prepared with different isocyanate indices, exhibit high porosities, high specific surface areas, ultralow thermal conductivity, and excellent ...

Recent advances of privacy-preserving machine learning based on (Fully) Homomorphic Encryption

open access: yesSecurity and Safety
Fully Homomorphic Encryption (FHE), known for its ability to process encrypted data without decryption, is a promising technique for solving privacy concerns in the machine learning era. However, there are many kinds of available FHE schemes and way more

Neuropile organization in the brain of Acromyrmex (Hymenoptera, Formicidae) during the post-embryonic development

open access: yesBrazilian Archives of Biology and Technology, 2004
Neuropile is the region of the central nervous system where the synapses and neurons branching occur. During the development of an holometabolous insect can occurs break of the neurons fibers forming new axon and dendrites and their distribution in brain

Multivariate Screening and Automated Clustering of Macrophage Immunoreactome to Nanoparticles and Photothermal Therapy

open access: yesAdvanced Science, EarlyView.
Predicting immune responses to treatments, including nanomedicines, with high throughput test is challenging due to the immunoreactome's complexity and plasticity. A predictive screening platform integrating pathway activation and gene profiling in macrophages has been developed as a versatile tool for designing effective immunotherapies.

Evolution of thorax architecture in ant castes highlights trade-off between flight and ground behaviors

open access: yeseLife, 2014
The concerted evolution of morphological and behavioral specializations has compelling examples in ant castes. Unique to ants is a marked divergence between winged queens and wingless workers, but morphological specializations for behaviors on the ground

Ant groups optimally amplify the effect of transiently informed individuals

open access: yesNature Communications, 2015
To cooperatively transport a large load, it is important that carriers conform in their efforts and align their forces. A downside of behavioural conformism is that it may decrease the group’s responsiveness to external information.

Stereotyped Subclones Revealed by High‐Density Single‐Cell Lineage Tracing Support Robust Development

open access: yesAdvanced Science, EarlyView.
Based on a well‐established in vitro directed differentiation model and an integrated analysis of high‐density cell lineage trees (CLTs) and single‐cell transcriptomes, it is demonstrated that many subclones are formed by sub‐CLTs resembling each other in terms of both cell type compositions and topological structures.

Accidental consumption of Atta cephalotes (Hymenoptera: Formicidae) by Artibeus lituratus (Chiroptera: Phyllostomidae)

open access: yesMammalogy Notes, 2017
During a 6-months research carried out in the Robles village (Jamundí municipality, Valle del Cauca Department, Colombia) in 2014, bat feces were collected to determine the diet of fruit-eating bats. This study area included farms and tropical dry forest

Kummer Theory for Drinfeld Modules

open access: yes, 2012
Let {\phi} be a Drinfeld A-module of characteristic p0 over a finitely generated field K. Previous articles determined the image of the absolute Galois group of K up to commensurability in its action on all prime-to-p0 torsion points of {\phi}, or ...
