Integrating artificial intelligence into venous thromboembolism care: Predictive models, implementation challenges, and future directions

Oscar Moreno · Ruoliu Zhang · Andrew Huang · Yanqing Zhao · y 7 más

Artificial intelligence (AI) has the potential to support personalized, multidisciplinary, data-driven care for venous thromboembolism (VTE) prevention, detection, imaging, management, and follow-up. We reviewed 23 studies: 20 prediction or detection studies were assessed with PROBAST+AI, while 3 evaluated clinical-imp...

Life of early mammals: a new, exceptionally preserved fossil mammal from the Early Cretaceous of NE China

Yan ZHAO · Michael BENTON · Elis NEWHAM · Vincent FERNANDEZ

We propose a propagation phase contrast synchrotron radiation X-ray micro computed tomography (PPC-SRµCT) study of an unreported Early Cretaceous mammaliaform fossil which is a new docodontan species. This fossil is superbly preserved with articulated cheek teeth and skeleton, and soft tissues including fur, whiskers,...

Comprehensive comparison of six optimization algorithms for automated population pharmacokinetic model selection via two simulation studies and eleven real case studies

Pierre, Matthias · Mihaljevic, Frano · Celliere, Geraldine · Bertrand, Julie

Background and objectives: Prior efforts to automate population pharmacokinetic structural and statistical model selection have explored various algorithms with mixed results. This study is conducting a comprehensive comparison of six distinct optimization algorithms for selecting pharmacokinetic and target-mediated dr...

Surface modifications of nanomaterials used for surface-enhanced Raman scattering measurements

Jan, Krajczewski · Andrzej, Kudelski

The efficiency of generating a Raman signal from molecules adsorbed on certain surfaces can be increased by many orders of magnitude - an effect known as surface-enhanced Raman scattering (SERS). Substrates for SERS measurements are often coated with layers of other materials. This increases the distance between the mo...

Weighted partial sums of a random multiplicative function and their positivity

Shuming Liu · Bing He

In this paper, we study the probability that some weighted partial sums of a random multiplicative function $f$ are positive. Applying the characteristic decomposition, we obtain that if $S$ is a non-empty subset of the multiplicative residue class group $(\mathbb{Z}/m\mathbb{Z})^{\times}$ with $m$ being a fixed positi...

An estimate for incomplete mixed character sums and applications

Arpan Chandra Mazumder · Giorgos Kapetanakis · Sushant Kala · Dhiren Kumar Basnet

Let $q$ be a prime power and $m>1$ be any integer. Let $\mathbb F_{q^m}$ be the finite field of order $q^m$ and $θ\in\mathbb F_{q^m}$ be such that $\mathbb F_{q^m} = \mathbb F(θ)$. We obtain a nontrivial bound for the mixed character sum $\sum_{x \in\mathbb F}χ(θ+x)ψ(x)$, where $χ$ and $ψ$ are multiplicative and additi...

A human-in-the-loop label error detection framework applied to Arabic-script HTR datasets

Sana Sabah Al-azzawi · Elisa Barney · György Kovács · Marcus Liwicki

Despite recent advances, Handwritten Text Recognition (HTR) for Arabic-script languages still lags behind Latin-script HTR. Part of the problem is dataset quality. To help closing this gap, we propose a two-stage framework (CER-HV) for detecting label errors. Stage 1 (CER) is a Character-Error-Rate-based noise detector...

Rubidium and Cesium Nitrides at Megabar Pressures

Umbertoluca RANIERI · AKUN LIANG · James SPENDER · Lourenço CUNHA CARIANO FERNANDES TAVARES · y 4 más

In our recent investigations, we discovered a plethora of new rubidium–nitrogen and cesium–nitrogen compounds—i.e. a staggering 11 new solids—at pressures up to 50 GPa. However, no investigation on alkali metals–N systems beyond 60 GPa has been reported in the literature, and there is no doubt that many more new alkali...

Learning ultra-compressible hyperelasticity with splines: Constitutive asymmetries and non-unique representations

Miguel Angel Moreno-Mateos · Simon Wiesheier · Paul Steinmann · Ellen Kuhl

Highly compressible solids, such as foams, exhibit complex responses, including pronounced tension-compression asymmetry. Capturing such behaviors within unified hyperelastic frameworks remains challenging. Invariant-based hyperelastic models are commonly identified from standard tests such as homogeneous uniaxial tens...
