Passives and impersonals [PDF]

Journal of Linguistics, 2003
This paper argues that the term ‘passive’ has been systematically misapplied to a class of impersonal constructions that suppress the realization of a syntactic subject. The reclassification of these constructions highlights a typological contrast between two types of verbal diathesis and clarifies the status of putative ‘passives of unaccusatives’ and

Data-Driven Robust Passivity-Based Controller Design for Grid-Connected Converters

, 2023
Due to the integration of renewable-based Distributed Generation Units (DGUs), Energy Storage Systems (ESSs) and electric car charging stations, more and more power electronic converters are connected to the grid. In grids with a high penetration rate of

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Nonfragile Observer-Based Control With Passivity and H_∞ Performance for a Class of Power-Line Inspection Robots With Input Time-Delay

IEEE Access
This study introduces a nonfragile observer-based control strategy for power-line inspection robots (PILRs) that adeptly tackles input time delays while integrating passivity and $H_{\infty }$ performance. The research commences with the development of

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

On ϱ-passivity

IFAC-PapersOnLine, 2023
We discuss passivity beyond continuous-time systems by highlighting several inconsistencies of the definition currently in use, for instance when applied to discrete-time systems, and by motivating the need for a new and more consistent notion. Hence, we propose a new definition, ϱ-passivity, that addresses the raised issues and that, as a result, is ...

Bilateral Energy Transfer for high fidelity haptic telemanipulation

, 2009
Among the methods to grant the stability of a telemanipulation system, the bilateral time domain passivity framework has the appealing characteristic to consider both, force and velocity signals exchanged between master and slave systems, and the power ...

Passivity-based posture control of a humanoid robot using a power-conserved transformation

, 2021
This paper proposes a passivity-based regulator for the balance of a humanoid robot. This regulator can dynamically stabilize internal motions as well as the configuration of a floating base. Using a unique transformation that conserves the power, we can

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Pose Synchronization for Quadrotor Networks under Fixed General Interconnection Topology: A Passivity Approach

SICE Journal of Control, Measurement, and System Integration, 2018
In this paper, a distributed 3-D pose synchronization law is proposed for a group of networked quadrotors. The quadrotor network consisting of multiple quadrotors with dynamics and interconnection topology between them is first defined, and then, the ...
