Cross-domain few-shot learning for hyperspectral image classification based on mixup foundation model

Naeem Paeedeh · Mahardhika Pratama · Ary Shiddiqi · Zehong Cao · y 2 más

Although cross-domain few-shot learning (CDFSL) for hyper-spectral image (HSI) classification has attracted significant research interest, existing works often rely on an unrealistic data augmentation procedure in the form of external noise to enlarge the sample size, thus greatly simplifying the issue of data scarcity...

Study the ship engine speed limiter effect with testbed experiment and on-board measurement, and comparative analysis with testbed propeller cycle responses

Mojibul Sajjad · Thuy Chu-Van · GM Hasan Shahariar · Kabir Adewale Suara · y 3 más

Transient ship manoeuvring introduces coupled speed-load dynamics that are inadequately represented by conventional propeller-law-based load models. This study examines the impact of engine speed-slope limiters (r min⁻1s⁻1) on transient load tracking, fuel consumption, and emissions using a combined experimental and an...

Wireless mobile charging for emergency electric vehicle routing: A mixed-integer and metaheuristic framework for in-motion energy transfer

Jingyi Zhao · Haoxiang Yang · Youxuan Pan · Yang Liu

As electric vehicles (EVs) become central to decarbonization efforts, the need for uninterrupted power supply in time-critical logistics, particularly in medical transportation, poses unique challenges for power systems integration. Conventional fixed or mobile charging infrastructure requires vehicle downtime, which m...

On a problem on a generalization of Euler's totient function

Campbell, John M.

Büyükaşik et al. [Publ. Math. Debrecen, 2024] introduced a family of generalizations of Euler's totient function $φ(n)$, by setting $φ_k(n) = \sum_{a} a^k$ for $a \in [1, n]$ such that $(a, n) = 1$, with $φ_0(n) = φ(n)$. Letting $\mathcal{D}_{s} = \{ k \geq s : \forall n \geq 1 \ φ_s(n) \mid φ_k(n) \}$, Büyükaşik et al...

SegRAG: Retrieval augmented spatial prompting for open vocabulary semantic segmentation

Abderrahmene Boudiaf · Irfan Hussain · Sajid Javed

Frozen segmentation foundation models often fail when the target class appears in a form that is weakly represented during pretraining. To address this problem, we introduce SegRAG, a retrieval-augmented inference-time spatial prompting pipeline for open-vocabulary semantic segmentation that uses frozen models without...

Johnson's determinantal identity for contiguous minors of Toeplitz matrices, with an accretive extension

Teng Zhang

Let $A$ be an $n\times n$ real Toeplitz matrix satisfying $A+A^{\top}=2\mathbb J_n$, where $\mathbb J_n$ is the all-ones matrix.If $A_r(i,j)$ denotes the $r\times r$ contiguous submatrix of $A$ consisting of rows $i,i+1,\dots,i+r-1$ and columns $j,j+1,\dots,j+r-1$, then for every $n\ge 2$ one has $$\det A_{n-1}(1,2)+\d...

Music as a form of art: Current findings and challenges of music neuroaesthetics research

E. Brattico · D. Marzano · G. Carraturo

In recent decades, empirical research on music, often grouped under the label of cognitive neuroscience of music, has approached music primarily as a biological, cognitive faculty, focusing on audiomotor predictive and reward mechanisms. More recently, the neuroaesthetics of music has expanded this focus to musical exp...

When trauma turns septic: Associated factors and focus-specific mortality in 61,399 patients from the TraumaRegister DGU®

O, Cruciger · T A, Schildhauer · C, Ull · J, Stein · y 3 más

Sepsis is a critical complication after severe trauma. This study aimed to identify factors associated with sepsis, to characterise sepsis foci in relation to injury pattern, and to evaluate the association of sepsis with multiple organ failure (MOF) and in-hospital mortality.This retrospective cohort study analysed Tr...

Multi-wavelength behaviour and lepto-hadronic modeling of PKS 0215+015 around the epoch of IceCube-220225A

Athira M. Bharathan · Markus Böttcher

The detection of high-energy astrophysical neutrinos has opened a new avenue for identifying cosmic particle accelerators. Blazars, active galactic nuclei (AGN) with relativistic jets oriented close to the observer's line of sight, are promising sites of hadronic interactions capable of producing PeV-scale neutrinos. W...

Mapping the science of aesthetic emotions

Valentin Wagner · Thomas Jacobsen

In this review, we trace the current state of research on aesthetic emotion in empirical aesthetics. Taking several theoretical contributions as a starting point, we highlight empirical studies that recently added to our knowledge in the field. Furthermore, we also highlight where the majority of recent work has been d...
