Chameleonic Color‐Variable Microbead Emitters for Multilevel Spectroscopic Encryption from Visible to Infrared Wavelengths

Advanced Optical Materials, EarlyView.
Whispering‐gallery‐mode microresonators with sharp resonant peaks enable photonic barcoding. Similar to a chameleon, a rare‐earth‐free microcavity with π‐conjugated PAHs enables visibleto‐near infrared color generation from a single microbead. The unique resonat emission (spectral barcode) can be dynamically transformed via excitation wavelength change,

Continual Learning for Multimodal Data Fusion of a Soft Gripper

Advanced Robotics Research, EarlyView.
Models trained on a single data modality often struggle to generalize when exposed to a different modality. This work introduces a continual learning algorithm capable of incrementally learning different data modalities by leveraging both class‐incremental and domain‐incremental learning scenarios in an artificial environment where labeled data is ...

Language Acquisition and L2 Language: A Literature Review

Majapahit Journal of English Studies
Language acquisition, particularly second language (L2) learning, has been a central focus of linguistic and educational research. This literature review synthesizes recent studies (2020–2024) to explore key theories, factors, and methodologies in L2 ...

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

Advanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

When L1 takes precedence: revisiting semantic acquisition in diverse L2 learners

Frontiers in Education
This paper investigates the interaction between the Semantic Subset Principle (SSP) and first language (L1) influence in second language (L2) acquisition, focusing on ambiguous linguistic structures that involve subset-superset readings.

N-Drop and Determiners in Native and Non-Native Spanish: More on the Role of Morphology in the Acquisition of Syntactic Knowledge

Círculo de Lingüística Aplicada a la Comunicación, 2023
In order to investigate whether the acquisition of N-drop (null nouns) is related to the acquisition of the agreement system of Spanish determiners this paper analyzes L1 longitudinal Spanish data from two children and L2 longitudinal data from two ...

Variation in motion events: Theory and applications [PDF]

, 2012
This chapter analyses the role of intratypological and dialectal variation in the lexicalisation of motion events (Talmy 1991, 2000) and its application to second language acquisition.

Constructing a second language: some final thoughts [PDF]

, 2009
All the papers in this special section address issues central to cognitive linguistics research: usage-based models with their focus on frequency; multi-word units and the relationship between lexical and grammatical knowledge; and the nature of lexical ...

CDK4/6 Inhibition Induces CD8+ T Cell Antitumor Immunity via MIF‐Induced Functional Orchestration of Tumor‐Associated Macrophages

Advanced Science, EarlyView.
CDK4/6 inhibition promotes CD8+ T cell expansion through tumor‐macrophage crosstalk by activating HIF‐1α and enhancing MIF‐CD44/CD74 signaling. This reprograms TAMs to boost MHC‐I antigen presentation, and CDK4/6 inhibitor‐trained M1 TAM supernatant therapy synergizes with low‐dose PD‐1 blockade to restore antitumor immunity.
