Investigation of the Impact of Thionine Functionalization on Magnetoelastic Sensor Performance.

This study investigates the functionalization of gold-coated magnetoelastic sensors with thionine molecules, focusing on resonance frequency shifts. The functionalization process was characterized by using Raman spectroscopy and analyzed via scanning electron microscopy and atomic force microscopy, revealing the progressive formation of molecular clusters over time. Our results demonstrate that longer functionalization time leads to saturation of surface coverage and cluster formation, impacting the sensor's resonance frequency shifts.

Structural transitions of ionic microgel solutions driven by circularly polarized electric fields.

In this work, a theoretical approach is developed to investigate the structural properties of ionic microgels induced by a circularly polarized (CP) electric field. Following a similar study on chain formation in the presence of linearly polarized fields [T. Colla , , 2018, , 4321-4337], we propose an effective potential between microgels which incorporates the field-induced interactions a static, time averaged polarizing charge at the particle surface.

Quantum-State Texture and Gate Identification.

We introduce and explore the notion of texture of an arbitrary quantum state, in a selected basis. In the first part of this Letter we develop a resource theory and show that state texture is adequately described by an easily computable monotone, which is also directly measurable. It is shown that textures are useful in the characterization of unknown quantum gates in universal circuit layers.

Exceptional Point and Hysteresis in Perturbations of Kerr Black Holes.

We employ the isomonodromic method to study linear scalar massive perturbations of Kerr black holes for generic scalar masses Mμ and generic black hole spins a/M. We find that the longest-living quasinormal mode and the first overtone coincide for (Mμ)_{c}≃0.370 4981 and (a/M)_{c}≃0.

Simultaneous Unbinned Differential Cross-Section Measurement of Twenty-Four Z+jets Kinematic Observables with the ATLAS Detector.

Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Measurement of Λ_{b}^{0}, Λ_{c}^{+}, and Λ Decay Parameters Using Λ_{b}^{0}→Λ_{c}^{+}h^{-} Decays.

A comprehensive study of the angular distributions in the bottom-baryon decays Λ_{b}^{0}→Λ_{c}^{+}h^{-}(h=π,K), followed by Λ_{c}^{+}→Λh^{+} with Λ→pπ^{-} or Λ_{c}^{+}→pK_{S}^{0} decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 9  fb^{-1} collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, the Λ_{b}^{0}→Λ_{c}^{+}h^{-} decay parameters are measured.

Biofilm formation by the plant growth promoting bacterium Bacillus cereus (EB-40).

The objective of this work was to investigate the biofilm production capacity of the isolate EB-40 (Bacillus cereus) in a culture medium for the multiplication of microorganisms and in roots of in vitro grown banana explants. It was observed that the isolate was able to produce biofilms in tryptone, soy and agar (TSA) culture medium and in the roots of explants. The format, architecture and location of the biofilms in TSA culture medium presented an exopolymer matrix formed by EB-40 presented coccoid bacillary cells and fibrillar structures.

Biogenic silver nanoparticle as an adjuvant in an S1 subunit recombinant vaccine.

Adjuvants are crucial for maintaining specific, protective, and long-lasting immunity. Here, we aimed to evaluate the antigenic and immunogenic activity of a recombinant form of the S1 domain of the Spike protein, associated with biogenic silver nanoparticles (bio-AgNP) and Alhydrogel as an alternative and conventional adjuvant, respectively, for a SARS-CoV-2 subunit vaccine. We produced and evaluated the antigenicity of the recombinant S1 (rS1) protein by testing its recognition by antibodies present in SARS-CoV-2 positive human serum.

An assessment of plant growth and physiological responses in annual crops grown in P deficient soils inoculated with indigenous arbuscular mycorrhizal fungi.

The influence of arbuscular mycorrhizal fungi (AMF) inoculation on the growth and physiology of Phaseolus vulgaris L. and Zea mays L. in the Brazilian tropical seasonal dry forest is not well known.

New insight on the acute CCl-induced hepatotoxicity model in rats.

The CCl-induced hepatotoxicity model is a traditional preclinical assay applied to evaluate potential hepatoprotective compounds. However, several studies have used it with inappropriate dose and exposure time, generating both weak response or irreversible liver injury, as well as lack of representative liver and plasma biomarkers. Therefore, this study aims to determine the best dose and exposure time of CCl in Wistar rats, permitting a proper evaluation of potential hepatoprotective effect.

Prioritizing questions and topics for the development of guidelines and consensus-based recommendations supported by ILAE: A scoping review and proposal of prioritization criteria.

Clinical practice guidelines (CPGs) and consensus-based recommendations (CBRs) require considerable effort, collaboration, and time-all within the constraints of finite resources. Professional societies, such as the International League Against Epilepsy (ILAE), must prioritize what topics and questions to address. Implementing evidence-based care remains a crucial challenge in clinical practice.

Transfusion Practices in Traumatic Brain Injury: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Data Sources: Electronic databases were searched from inception to October 2024.

The photochemical inheritance of Eduardo Lissi and Juan Grotewold and the intersystem crossings with other inheritances.

In 1963, Eduardo Lissi and Juan Grotewold started a chemical kinetics and photochemistry group at the School of Sciences at the University of Buenos Aires (Facultad de Ciencias Exactas y Naturales, FCEN, UBA). Political circumstances in Argentina and in Chile were a great determinant of the evolution, dispersion, and re-encounters of the group members. The initial graduate students in the group developed their own research groups working in various Countries and on a variety of projects.

TccP4: a novel effector identified in the strain 1551-2 required for attaching and effacing lesion formation on infected Nck-null cells.

is a pathogen that causes sporadic cases and outbreaks of diarrhea. The main virulence feature of this bacterium is the attaching and effacing (AE) lesion formation on infected intestinal epithelial cells, which is characterized by the formation of pedestal-like structures that are rich in F-actin. The Brazilian 1551-2 strain can recruit F-actin using both the Nck-dependent and the Nck-independent pathways, the latter of which uses an adaptor protein named Tir-cytoskeleton coupling protein (TccP/EspF).

Riga-Fede disease (RFD) is a rare, benign condition marked by traumatic ulceration on the tongue's ventral side in infants. It arises from friction between the tongue and lower incisors during sucking, potentially worsening into a keratinized lesion if the cause is not addressed. This report details the case of a 1-year-6-month-old male with hydrocephalus, cleft palate, corpus callosum dysgenesis, neuropsychomotor developmental delay, and tracheostomy and gastrostomy needs.
