Fish Scales: A Multifunctional Biomaterial from Nature

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Performance of RSMA-Based UOWC Systems Over Oceanic Turbulence Channel With Pointing Errors

IEEE Open Journal of the Communications Society
Underwater optical wireless communication (UOWC) systems face significant challenges due to oceanic turbulence and pointing errors (PE), which can degrade system performance. Moreover, interference is another challenge in UOWC, considering the consistent

Setting the Record Straight: The Intellectual Legacy of H. Igor Ansoff (1918–2002)

Strategic Change, EarlyView.
ABSTRACT This study presents a comprehensive annotated bibliography of H. Igor Ansoff's intellectual contributions, addressing significant gaps in existing citation databases such as Scopus and Web of Science, which capture only 9 to 15 percent of his work.

Wake sorting, selective predation and biogenic mixing: potential reasons for high turbulence in fish schools [PDF]

PeerJ, 2013
There has been debate about animals’ contribution to ocean circulation, called biomixing, or biogenic mixing. The energy input of schooling fish is significant but the eddies may be too small; so energy is dissipated as heat before impacting oceanic ...

Unveiling the Dual Role of Intellectual Capital in Value Creation and Financial Distress: Underlying Critical Moderators

Knowledge and Process Management, EarlyView.
ABSTRACT This study examines the extent to which intellectual capital (IC) supports firms' value generation and financial resilience, and how these effects are conditioned by profitability. IC is quantified using the “modified value‐added intellectual coefficient (MVAIC)” for a panel of 103 manufacturing firms listed on the Pakistan Stock Exchange over

An autonomous and economical benthic incubation chamber for measuring dissolved oxygen fluxes in shallow, low‐flow environments

Limnology and Oceanography: Methods, EarlyView.
Abstract Benthic incubation chambers enclose a known volume of water overlying a known area to measure water chemistry changes and are typically used to quantify the metabolic activity of benthic organisms or communities. Here we present an economical benthic incubation chamber for shallow, low‐flow environments, built using off‐the‐shelf components ...

Simulation of transmission characteristics of oceanic wireless optical communication systems based on orbital angular momentum multiplexing with space-time coding

Tongxin xuebao, 2020
In order to mitigate the crosstalk caused by oceanic turbulence in the underwater wireless orbital angular momentum multiplexing optical communication system, the application of space-time coding technology in the system was studied.Based on Rytov ...

Numerical Insights Into the Resistance Reduction Mechanisms of Forward Tapered Transoms in High‐Speed Catamaran: A Computational Fluid Dynamics‐Based Study

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study investigates the hydrodynamic influence of forward transom tapering on a displacement catamaran hull using computational fluid dynamics (CFD) simulations. Five taper configurations ranging from a vertical transom base design to a fully tapered stern (1.00B) were evaluated over a wide Froude number range (Fr = .3 to 1.0).

Permafrost Mass Wasting in Ice‐Rich Landscapes: Recent Advances (2013 to 2024) on Mechanisms, Dynamics and Impacts

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...
