A review of the methods for studying biotic interactions in phenological analyses

Phenological events play a key role modulating ecosystem services; however, the complex and interlinked nature of ecosystems indicates that interactions among different taxa during phenological events can have consequences for the entire ecosystem. Currently, there is a lack of a unified criteria on the methodologies studying phenology and biotic interactions. We performed an extensive integrative review of works evaluating phenology and biotic interactions. We identified four broad categories of studies that have explored biotic interactions within phenology research: (a) spatial and temporal asynchronies, (b) biotic factors as covariates, (c) simulation studies and (d) interaction indices. We found that spring phenology has received much more attention than any other season, while mutualistic and obligated interactions, as well as trophic interactions and networks have been explored more routinely than facilitation or competition. Authors tend to interpret coexistence among species as biotic interactions without any direct measurement, particularly in spatial and temporal asynchrony studies, but this also occurs to a certain extent in all categories. We also found a lack of formal examination in most studies exploring phenological mismatches in response to climate change. We propose a conceptual framework for the inclusion of phenology in the study of biotic interactions that apportions research into the conceptualisation and modelling of biotic interactions. Conceptualisation explores phenological data, types of interactions and the spatiotemporal dimensions, which all determine the representation for biotic interactions within the modelling framework, and the type of models that are applicable. Finally, we identify emerging opportunities to investigate biotic interactions in phenology research, including spatially and temporally explicit species distribution models as proxies for phenological events and the combination of novel technologies (e.g. acoustic recorders, telemetry data) to quantify interactions

Cómo guardar granos húmedos sin perder calidad

El temporal de lluvia, que comenzó a finales de abril y se extendió hasta comienzos de mayo en algunas regiones, provocó la interrupción de las labores de trilla y la aparición de serios problemas vinculados con alta humedad de granos como la presencia de brotado, dehiscencia, enfermedades y disminuciones en el peso específico. Dado este panorama, y sobre todo las complicaciones derivadas de los granos húmedos que aumentan el riesgo de deterioro en la poscosecha, técnicos del INTA Pergamino y Balcarce -Buenos Aires- brindan recomendaciones para conservar el mayor tiempo posible la calidad de la producción almacenada en silobolsas y silos convencionales.EEA PergaminoFil: Roskopf, Ruben.

Atomic-Scale Variations of the Mechanical Response of 2D Materials Detected by Noncontact Atomic Force Microscopy

We show that noncontact atomic force microscopy (AFM) is sensitive to the local stiffness in the atomicscale limit on weakly coupled 2D materials, as graphene on metals. Our large amplitude AFM topography and dissipation images under ultrahigh vacuum and low temperature resolve the atomic and moiré patterns in graphene on Pt (111), despite its extremely low geometric corrugation. The imaging mechanisms are identified with a multiscale model based on density-functional theory calculations, where the energy cost of global and local deformations of graphene competes with short-range chemical and long-range van der Waals interactions. Atomic contrast is related with short-range tip-sample interactions, while the dissipation can be understood in terms of global deformations in the weakly coupled graphene layer. Remarkably, the observed moiré modulation is linked with the subtle variations of the local interplanar graphene-substrate interaction, opening a new route to explore the local mechanical properties of 2D materials at the atomic scaleWe thank the Marie Curie ITN Network “ACRITAS” (Grant No. FP7-PEOPLE-2012-ITN-317348) funded by the European Commission under the FP7 Marie Curie PEOPLE programme and the Spanish MINECO (Projects No. CSD2010-00024, No. MAT2011-23627, No. MAT2013-41636-P, and No. MAT2014-54484-P) for financial support.

Robot-Aided Systems for Improving the Assessment of Upper Limb Spasticity: A Systematic Review

This article belongs to the Special Issue Sensors Technology for Medical Robotics.Spasticity is a motor disorder that causes stiffness or tightness of the muscles and can interfere with normal movement, speech, and gait. Traditionally, the spasticity assessment is carried out by clinicians using standardized procedures for objective evaluation. However, these procedures are manually performed and, thereby, they could be influenced by the clinician’s subjectivity or expertise. The automation of such traditional methods for spasticity evaluation is an interesting and emerging field in neurorehabilitation. One of the most promising approaches is the use of robot-aided systems. In this paper, a systematic review of systems focused on the assessment of upper limb (UL) spasticity using robotic technology is presented. A systematic search and review of related articles in the literature were conducted. The chosen works were analyzed according to the morphology of devices, the data acquisition systems, the outcome generation method, and the focus of intervention (assessment and/or training). Finally, a series of guidelines and challenges that must be considered when designing and implementing fully-automated robot-aided systems for the assessment of UL spasticity are summarized

The photoelectric effect and study of the diffraction of light: Two new experiments in UNILabs virtual and remote laboratories network

This work describes two experiments: “study of the diffraction of light: Fraunhofer approximation” and “the photoelectric effect”. Both of them count with a virtual, simulated, version of the experiment as well as with a real one which can be operated remotely. The two previous virtual and remote labs (built using Easy Java(script) Simulations) are integrated in UNILabs, a network of online interactive laboratories based on the free Learning Management System Moodle. In this web environment, students can find not only the virtual and remote labs but also manuals with related theory, the user interface description for each application, and so on

Nitrene-carbene-carbene rearrangement. photolysis and thermolysis of tetrazolo[5,1- a ]phthalazine with formation of 1-phthalazinylnitrene, o-cyanophenylcarbene, and phenylcyanocarbene

1-Azidophthalazine 9A is generated in trace amount by mild FVT of tetrazolo[5,1-a]phthalazine 9T and is observable by its absorption at 2121 cm-1 in the Ar matrix IR spectrum. Ar matrix photolysis of 9T/9A at 254 nm causes ring opening to generate two conformers of (o-cyanophenyl) diazomethane 11 (2079 and 2075 cm-1), followed by (o-cyanophenyl)carbene 312, cyanocycloheptatetraene 13, and finally cyano(phenyl)carbene 314 as evaluated by IR spectroscopy. The two carbenes 312 and 314 were observed by ESR spectroscopy (D|hc = 0.5078, E|hc = 0.0236 and D|hc = 0.6488, E|hc = 0.0195 cm-1, respectively). The rearrangement of 12 â., 13 â., 14 constitutes a carbene-carbene rearrangement. 1-Phthalazinylnitrene 310 is observed by means of its UV-vis spectrum in Ar matrix following FVT of 9 above 550 C. Rearrangement to cyanophenylcarbenes also takes place on FVT of 9 as evidenced by observation of the products of ring contraction, viz., fulvenallenes and ethynylcyclopentadienes 16-18. Thus the overall rearrangement 10 → 11 → 12 â., 13 â., 14 can be formulated

Production of antigens and development of candidates for vaccines against porcine circovirus 2 (PCV2)

Porcine circovirus (PCV2)-associated disease is one of the most worrisome diseases affecting the porcine sector, causing significant economic losses. Although the currently available vaccines reduce infections and virulence, they are not effective in eradicating the virus. In addition, the high rate of mutation of the virus together with the selective pressure exerted by these vaccines have favoured the appearance of new strains and changes in the dominant genotype of the virus. Recombinant vaccines emerge as a viable alternative to the use of attenuated viruses. However, they are not capable of inducing a potent cellular immune response capable of neutralizing the virus. ADL BIONATUR SOLUTIONS is developing recombinant vaccines based on the expression of neutralizing epitopes of the PCV2 capsid protein fused to sequences for inducing specific cellular immunity. This project has been focused on the production of antigens/candidates for vaccines against PCV2. The antigens could be also used to develop technical tools in order to analyze the in vivo efficacy of the vaccines in raising the humoral and cellular components of the immune response.Methods: The production of the antigens was performed in the FLYLIFE platform, based on the use of insect cells as biofactories for the production of proteins of interest. The expression of the protein was driven by a baculovirus vector infecting larvae of the insect Trichoplusia ni. In addition, a protocol was designed to obtain the antigens under the requirements of concentration and purity for immunity tests.Results: After the expression of the antigens in the larvae of the insect, different conditions of solubilization and purification were analyzed, which allowed obtaining the antigens with a 60-78% of purity. Currently, immunity assays are being carried out in mice to verify an improvement in the immune response of the vaccine candidate against PCV2

Joint Ultra-wideband Characterization of Azimuth, Elevation and Time of Arrival with Toric Arrays

In this paper, we present an analytical framework for the joint characterization of the 3D direction of arrival (DoA), i.e., azimuth and elevation components, and time of arrival (ToA) in multipath environments. The analytical framework is based on the use of nearly frequency-invariant beamformers (FIB) formed by toric arrays. The frequency response of the toric array is expanded as a series of phase modes, which leads to azimuth–time and elevation–time diagrams from which the 3D DoA and the ToA of the incoming waves can be extracted over a wide bandwidth. Firstly, we discuss some practical considerations, advantages and limitations of using the analytical method. Subsequently, we perform a parametric study to analyze the influence of the method parameters on the quality of the estimation. The method is tested in single-path and multipath mm-wave environments over a large bandwidth. The results show that the proposed method improves the quality of the estimation, i.e., decreases the level of the artifacts, compared to other state-of-art FIB approaches based on the use of single/concentric circular and elliptical arrays.PID2020-112545RB-C54 funded by MCIN/AEI/10.13039/501100011033PDC2022-133900-I00, PDC2023-145862-I00, TED2021-129938B-I00 and TED2021-131699B-I00 funded by MCIN/AEI/10.13039/501100011033European Union NextGenerationEU/PRTRUniversidad de Granada through grant PPJIB2022-05Predoctoral Grant FPU19/01251 and FPU19/04085.
