In this paper, we address the problem of approximating the atoms of a parametric dictionary A = {a(θ) : θ ∈ Θ}, commonly encountered in the context of sparse representations in "continuous" dictionaries. We focus on the case of translation-invariant dictionaries, where the inner product between a(θ) and a(θ) only depends on the difference θ − θ. We...

Circulating tumor DNA (ctDNA) has become an attractive biomarker in human oncology, and its use may be informative in canine cancer. Thus, we used droplet digital PCR or PCR for antigen receptor rearrangement, to explore tumor-specific point mutations, copy number alterations, and chromosomal rearrangements in the plasma of cancer-affected dogs. We...

Third-generation sequencing technologies allow to sequence long reads of tens of kbp, that are expected to solve various problems. However, they display high error rates, currently capped around 10%. Self-correction is thus regularly used in long reads analysis projects. We introduce CONSENT, a new self-correction method that relies both on multipl...

A low-cost, compact, and high gain Fabry–Perot cavity (FPC) antenna which operates at 300 GHz is presented. The antenna is fabricated using laser-cutting brass technology. The proposed antenna consists of seven metallic layers; a ground layer, an integrated stepped horn element (three-layers), a coupling layer, a cavity layer, and an aperture-frequ...

Uniaxial strain is a powerful approach to tune material properties and select between nearly degenerate phases. Here, uniaxial strain is used to stabilize the elusive 6×1 charge ordered ground state of IrTe2, revealing insights into its electronic structure and type-II topological Dirac states.
Collinearly placed patch antenna arrays, printed on high permittivity dielectric substrates, suffer from an unwanted inter element coupling due to strong surface waves. A new shaped Defected Ground Structure (DGS) is proposed to suppress such waves in between elements. A low dimensional μ shaped DGS is carved out in between two E-plane patch antenn...
Silicon Carbide (SiC) power transistors are more and more used in electric energy conversion systems. SiC power semiconductors devices, such as SiC metal-oxide-semiconductor field-effect transistor (MOSFET) can operate at higher frequency and higher temperature compared to Silicon power MOSFET or insulated-gate bipolar transistor. However, the matu...
U-Th-Pb geochronology of REE-bearing minerals such as monazite and other phosphates has become a precise tool to date mineralization events through geological time. In the E-Colombian Guainía department, from 3 colluvial sites over western Guiana Shield Mesoproterozoic rocks Nb-Ta, U-Th and REE bearing minerals probably of pegmatitic origin were sa...
Examination of Hkamti and Tanai Burmese ambers reveals two new genera and species of †Lancepyrinae: Protopyris myanmarensis Jouault & Nel gen. et sp. nov. and Burmapyris azevedoi Jouault, Perrichot & Nel gen. et sp. nov. Protopyris Jouault & Nel gen. nov. is the first Bethylidae described from amber of the Hkamti deposit (lower Albian, mid-Cretaceo...
Few global syntheses of oxygen and carbon isotope composition of pedogenic carbonates have been attempted, unlike marine carbonates. Pedogenic carbonates represent in-situ indicators of the climate conditions prevailing on land. The δ18O and δ13C values of pedogenic carbonates are controlled by local and global factors, many of them not affecting t...
