Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

Small, EarlyView.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Long period nodal motion of sun synchronous orbits [PDF]

An approximative model is formulated for assessing these perturbations that significantly affect long term modal motion of sun synchronous orbits. Computer simulations with several independent computer programs consider zonal and tesseral gravitational ...

Filling a Gap in Materials Mechanics: Nanoindentation at High Constant Strain Rates up to 105 s−1

Small, EarlyView.
A piezoelectric nanoindentation platform enables constant strain‐rate testing up to 105 s−1, extending experimental capabilities to extreme deformation regimes. Distinct hardness upturns are revealed across crystalline and amorphous materials, verified as intrinsic responses through quasi‐static reloading.

Accuracy of Stanton’s Formula Used for the Data Processing of a Pendulum Friction Test

Tribology Online
Pendulum friction-tester is specifically useful for experiments in biotribological field because that is good at the measure on circular sliding surfaces, like as synovial joints, joint prostheses, eye balls, or contact lenses. Stanton’s formula has been

Posidonia oceanica Leaves as a Natural Filler for Poly(Butylene Succinate‐Co‐Adipate) Composites: Characterization and Biodegradation Assessment in Seawater

Journal of Vinyl and Additive Technology, EarlyView.
This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.

Estimating crippling loss from hunting with multistate models: a case study on northern bobwhites

Wildlife Biology, EarlyView.
Hunting as a recreational pursuit provides an important ecosystem service worldwide. Harvest management plays a vital role in regulating wildlife take to ensure long‐term population sustainability and meet value‐based objectives (e.g. hunter satisfaction). However, managers rarely have complete control or observability of harvest mortality.

Dynamic Resource Allocation Optimisation and Security‐Resilient Control for Bandwidth‐Limited Network Control Systems With Data Conflicts

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Networked control systems (NCSs) often suffer from performance degradation due to limited communication bandwidth, which can cause data transmission conflicts and packet loss. Existing scheduling strategies may fail to simultaneously meet the real‐time requirements and the importance of multisensor data, and they are particularly vulnerable ...

The unintended consequences of the blended workforce in the Australian Public Service: Effects on middle manager well‐being

Australian Journal of Public Administration, EarlyView.
Abstract The adoption of a blended workforce model, comprising both ongoing and non‐ongoing employees, has become increasingly common in public sector organisations. Despite known challenges, including high turnover and knowledge gaps, its impact on middle managers’ well‐being remains understudied.
