Monitoring of water freeze-thaw cycle by means of an etched single-mode - multimode - single-mode fiber-optic refractometer
As an alternative to the different technologies that permit the detection of in-situ ice formation on different surfaces, this contribution proposes the design of an etched single-mode – multimode – single-mode (E-SMS) ... -
Mrna vaccines against sars-cov-2: advantages and caveats
The application of BNT162b2 and mRNA-1273 vaccines against SARS-CoV-2 infection has constituted a determinant resource to control the COVID-19 pandemic. Since the beginning of 2021, millions of doses have been administered ... -
A multi-object grasp technique for placement of objects in virtual reality
Some daily tasks involve grasping multiple objects in one hand and releasing them in a determined order, for example laying out a surgical table or distributing items on shelves. For training these tasks in Virtual Reality ... -
Multi-scale approach to forest functioning of Pinus sylvestris L. and Fagus sylvatica L. mixtures of the Pyrenees under global change
Hoy en día, los bosques mixtos son cada vez más reconocidos como superiores a los bosques puros en cuanto a la provisión de una completa gama de bienes y servicios ecosistémicos. La gestión de los bosques en una condición ... -
Multigrid solvers for multipoint flux approximations of the Darcy problem on rough quadrilateral grids
In this work, an efficient blackbox-type multigrid method is proposed for solving multipoint flux approximations of the Darcy problem on logically rectangular grids. The approach is based on a cell-centered multigrid ... -
Multipactor breakdown analysis of Ku-band meandered low-pass filter
In this work, a very compact rectangular waveguide low-pass filter with meandered topology based on commensurate lines for Ku-band satellite applications is analysed for high-power handling capabilities. The device consists ... -
Multiparameter sensor based on a multiinterferometric serial configuration for temperature and strain measurements
In this work, a multi-parameter point sensor based on the combination of Fabry-Perot (FP) and the anti-resonant (AR) reflecting guidance in cascade configuration is proposed and experimentally demonstrated. This structure, ... -
Multiplexing optical fiber Fabry-Perot interferometers based on air-microcavities
In this work we demonstrate the multiplexing capability of new optical fiber Fabry-Perot interferometers based on airmicrocavities using a commercial FBG interrogator. Three optimized air-microcavity interferometer sensors ... -
Multivariate statistical analysis and odor taste network to reveal odor taste associations
Odor−taste association has been successfully applied to enhance taste perception in foods with low sugar or lowsalt content. Nevertheless, selecting odor descriptors with a given associated taste remains a challenge. In ... -
Mutual-coupling reduction in metamaterial substrate integrated waveguide slotted antenna arrays using metal fence isolators for SAR and MIMO applications
A new type of mutual coupling reduction technique is applied to metamaterial substrate integrated waveguide (SIW) slotted antenna array. The circular shaped reference SIW antenna array is constructed from Alumina substrate ... -
Nature-based strategies to regenerate the functioning and biodiversity of vineyards
Grapevine is one of the most important perennial fruit crops worldwide. Historically, vineyards were compatible with soil conservation practices and multitrophic biodiversity, but vineyards are now generally eroded and ... -
New approach to suppress mutual coupling between longitudinal-slotted arrays based on SIW antenna loaded with metal-fences working on VHF/UHF frequency-bands: study, investigation, and principle
In this work it is demonstrated that substrate integrated waveguide longitudinal slotted array antenna (SIWLSAA) which is loaded with metal fences exhibits high-isolation across VHF/UHF bands. A reference SIWLSAA used for ... -
New challenges in organic fertilization: soil quality indicators under long-term sewage sludge application
(2023) Tesis doctoral / Doktoretza tesiaSoils represent a fundamental part of life on Earth and represent a crucial player on climate change action, for their capacity to sequester atmospheric carbon (C) through organic matter stabilization, constituting one of ... -
New functions for Cyt proteins and sporulation determinants in Bacillus thuringiensis

New horizons in near-zero refractive index photonics and hyperbolic metamaterials
The engineering of the spatial and temporal properties of both the electric permittivity and the refractive index of materials is at the core of photonics. When vanishing to zero, those two variables provide efficient knobs ... -
A new role for aldosterone/mineralocorticoid receptor pathway in the development of mitral valve prolapse
La hipótesis de trabajo es que la vía Aldosterona/Receptor Mineralocorticoide (Aldo/RM) podría jugar un papel en el desarrollo del prolapso de la válvula mitral (PVM), modulando la activación de las células intersticiales ... -
A new study to suppress mutual-coupling between waveguide slot array antennas based on metasurface bulkhead for MIMO systems
In this paper, a new method is proposed to reduce mutual coupling between waveguide slot array (WSA) antennas based on metasurface technology. This is achieved by placing a metasurface bulkhead between the two WSA antennas. ... -
A new waveguide slot array antenna with high isolation and high antenna bandwidth operation on Ku- and K- Bands for radar and MIMO systems
In this paper a novel technique is proposed to reduce the mutual coupling between the radiating elements of a waveguide slot array antenna. This is achieved by inserting slots between the waveguide oval shaped slots. The ... -
Nodule carbohydrate catabolism is enhanced in the Medicago truncatula A17-Sinorhizobium medicae WSM419 symbiosis
