Experimental study towards the development of highly sensitive opto-mechanical sensors based on FSBS in telecom optical fibers.

The development of applications based on forward-stimulated Brillouin scattering (FSBS) in optical fibers has experienced a considerable increase in recent years, particularly in the area of fiber optic sensors. In this work, we present an experimental investigation to explore the limits of this physical mechanism in telecom optical fibers, whose results we think are of interest for the design of sensors in different areas. Specifically, we studied on the capability of the conventional probing method to detect FSBS in very short optical fibers, and the potential of FSBS to detect tiny diameter changes in the optical fiber.

Decorated Electrode Surfaces with Nanostructures and Metal-Organic Frameworks as Transducers for Sensing.

In this study, several materials are presented as modifiers of the screen-printed carbon electrodes with the aim of developing new sensing platforms for the voltammetric analysis of drugs. Specifically, Clotiapine and Sulfamethoxazole were selected as models for antipsychotics and antibiotics, respectively. Different nanostructures were studied as modifiers, including both transition metals and carbon-based materials.

Salmon-IgM Functionalized-PLGA Nanosystem for Florfenicol Delivery as an Antimicrobial Strategy against .

Salmonid rickettsial septicemia (SRS), caused by , has been the most severe health concern for the Chilean salmon industry. The efforts to control infections have focused on using antibiotics and vaccines. However, infected salmonids exhibit limited responses to the treatments.

Corollary discharge and anomalous self-experiences in schizophrenia and bipolar disorder: A specificity analysis.

Objective: The Corollary Discharge (CD) mechanism inhibits self-generated speech sound perception, appearing disrupted in schizophrenia and potentially contributing to Anomalous Self-Experiences (ASEs). However, it remains unclear if this alteration and its correlation with ASEs extend to other psychotic disorders.

Methods: Electroencephalography was used to study the N1 Event-Related Potential (ERP) as an index of CD-mediated suppression in the auditory cortex across thirty-five participants with schizophrenia, twenty-six with bipolar disorder, and thirty healthy controls.
