Maximal Speed of Glucose Change Significantly Distinguishes Prediabetes from Diabetes
Rapid changes in blood glucose levels can have severe and immediate health consequences, leading to the need to develop indices for assessing these rapid changes based on continuous glucose monitoring (CGM) data. We proposed a CGM index, maxSpeed, that represents the maximum of speed of glucose change (SGC) in a subject, respectively, and conducted a clinical study to investigate this index along with SGC mean (meanSpeed) and SGC standard deviation (sdSpeed), coefficient of variation (CV), stan…

If you're writing a library, you should really avoid #CMake. CMake is designed to lock you in. As in, once you release a #FreeSoftware project using CMake, you can't switch to another build system with causing real trouble to your users. And if you support multiple build systems, as soon as you start supporting CMake, some of your users are going to start locking everyone else in.
That's because CMake uses a custom package discovery mechanism that's hardly compatible with anything else, and that is so complex that it's very hard to reimplement it with any other build system. So when others start relying on the CMake config files being installed (and they naturally will, since that's how CMake does things), you can't stop installing them without actually breaking stuff. And if you want to preserve them without actually using CMake, well, good luck with that.
And if CMake is one of the options you support, then some of your consumers will accidentally start relying on it anyway. And this will be much worse for everyone, because now their projects won't work for people who build your project with any other build system. Which in turn will force more projects to use CMake anyway. Which in turn will make more people rely on CMake being used…
Use #Meson as the build system, it's clean and not designed to lock you in. Use pkg-config for library data; it's simple and portable.

Performance Portable Gradient Computations Using Source Transformation
Derivative computation is a key component of optimization, sensitivity analysis, uncertainty quantification, and nonlinear solvers. Automatic differentiation (AD) is a powerful technique for evaluating such derivatives, and in recent years, has been integrated into programming environments such as Jax, PyTorch, and TensorFlow to support derivative computations needed for training of machine learning models, resulting in widespread use of these technologies. The C++ language has become the de fa…

DBNets2.0: simulation-based inference for planet-induced dust substructures in protoplanetary discs
Dust substructures in protoplanetary discs can be signatures of embedded young planets whose detection and characterisation would provide a better understanding of planet formation. Traditional techniques used to link substructures' morphology to the properties of putative embedded planets present several limitations that the use of deep learning methods has partly overcome. In our previous work, we developed DBNets, a tool exploiting an ensemble of Convolutional Neural Networks (CNNs) to estim…

Choquet rating criteria, risk measures, and risk consistency
Credit ratings are widely used by investors as a screening device. We introduce and study several natural notions of risk consistency that promote prudent investment decisions in the framework of Choquet rating criteria. Three closely related notions of risk consistency are considered: with respect to risk aversion, the asset pooling effect, and the benefit of portfolio diversification. These notions are formulated either under a single probability measure or multiple probability measures. We s…

Data Synchronization at High Frequencies
Asynchronous trading in high-frequency financial markets introduces significant biases into econometric analysis, distorting risk estimates and leading to suboptimal portfolio decisions. Existing synchronization methods, such as the previous-tick approach, suffer from information loss and create artificial price staleness. We introduce a novel framework that recasts the data synchronization challenge as a constrained matrix completion problem. Our approach recovers the potential matrix of high-…

Multivariate Time-series Transformer Embeddings for Light Curves
Astronomical surveys produce time-series data by observing stellar objects across multiple wavelength bands. Foundational transformer-based models, such as Astromer, encode each time-series as a sequence of embeddings of uniform dimensions. However, such models operate independently on each band at a single time and do not natively leverage information across telescope filters. We extend this framework by introducing a fusion mechanism that maps the collection of single-band embeddings to a uni…

Variations in Dominant Wave Period in the Solar Atmosphere
Waves are an integral part of the solar atmosphere, and their characteristics (e.g., dominant period, range of periods, power, and phase angle) change on a diverse spatio-temporal scale. It is well well-established observationally that the dominant periods of solar oscillations are 5-min and 3-min in the photosphere and chromosphere, respectively. This shows that the wave spectra and their dominant periods evolve between these two layers. We present observational results that demonstrate variat…

Direct imaging discovery of a young giant planet orbiting on Solar System scales
HD 135344 AB is a young visual binary system that is best known for the protoplanetary disk around the secondary star. The circumstellar environment of the A0-type primary star, on the other hand, is already depleted. HD 135344 A is therefore an ideal target for the exploration of recently formed giant planets because it is not obscured by dust. We searched for and characterized substellar companions to HD 135344 A down to separations of about 10 au. We observed HD 135344 A with VLT/SPHERE in t…
