Tracing the geographical origin of Argentinean lemon juices based on trace element profiles using advanced chemometric techniques [PDF]
This study examines the application of chemometric techniques associated with trace element concentrations for origin evaluation of lemon juice samples. Seventy-four lemon juice samples from three different provinces of Argentina were evaluated according

Graph-based calibration transfer [PDF]
The problem of transferring calibrations from a primary to a secondary instrument, i.e. calibration transfer (CT), has been a matter of considerable research in chemometrics over the past decades. Current state-of-the-art (SoA) methods like (piecewise) direct standardization perform well when suitable transfer standards are available.

Plants rely on strigolactones (SLs) to regulate their development and form symbiotic relationships with microbes as part of the adaptive phosphorus (P) efficiency strategies. However, the impact of SLs on root-associated microbial communities in response

The Degrees of Freedom of Partial Least Squares Regression [PDF]
The derivation of statistical properties for Partial Least Squares regression can be a challenging task. The reason is that the construction of latent components from the predictor variables also depends on the response variable.

Engineering an asymmetric rhodamine dye suitable for developing ratiometric fluorescent probe
Fluorescent probes based on rhodamine skeleton are extensively used in biological imaging. However, the construction of ratiometric fluorescent probes based on the rhodamine skeleton without introducing additional fluorophores is still challenging ...

Detecting single molecules on large interfaces is challenging due to minimal perturbations on the sensing surface. Some biological systems achieve this feat using amplification mechanisms, but their molecular foundations remain unclear. To investigate, a Design of Experiments (DoE) approach examines how pH and ionic strength in conditioning solutions ...

Approximate Rank-Detecting Factorization of Low-Rank Tensors
We present an algorithm, AROFAC2, which detects the (CP-)rank of a degree 3 tensor and calculates its factorization into rank-one components. We provide generative conditions for the algorithm to work and demonstrate on both synthetic and real world data

Laser‐Induced Plasma Effects on Bond Breaking in High‐Density Polyethylene Pyrolysis
This study introduces a novel application of Laser‐Induced Breakdown Spectroscopy (LIBS) for bond breaking in high‐density polyethylene (HDPE), an area previously unexplored in laser‐plastic interactions. For the first time, a numerical model has been developed to differentiate between photon‐induced and laser field‐induced plasma, demonstrating the ...
