Experienced faculty members share their journey of teaching new classes

Natural Sciences Education, Volume 55, Issue 1, June 2026.
Abstract This study examined whether experience in the classroom changed the experience of teaching a new class in higher education. Weekly journals were maintained by three experienced teachers as they taught new courses at a land‐grant university.

Experimental Investigations on the Energy Absorption of Aluminum TPMS Structures Under Dynamic Loading

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Triply periodic minimal surfaces (TPMS) constitute a prominent class of cellular structures and have gained considerable attention in current research. These structures are genus‐infinite surfaces with zero mean curvature, which prevents self‐intersection. They also exhibit periodicity in all three spatial directions and exhibit enhanced multi‐

Map and Archival Evidence of the Historical Avulsion of the Brahmaputra River

The Geographical Journal, Volume 192, Issue 2, June 2026.
Short Abstract One of the world's great rivers, the Brahmaputra, avulsed—changed course—significantly sometime between the dates of 1765 and 1830. These are the dates of surveys by James Rennell (grey) and Richard Wilcox (black), both under the direction of the East India Company; no other surveys between these dates can refine the estimate of the ...

PID‐Like Robust Control of Non‐Minimum Phase Robotic Manipulators

International Journal of Robust and Nonlinear Control, Volume 36, Issue 8, Page 4490-4503, 25 May 2026.
ABSTRACT This paper proposes an output‐feedback tracking controller for non‐minimum phase nonlinear systems with unknown uncertainties and external disturbances, where not all states are measurable, and the zero dynamics are unstable. The approach combines a backstepping‐based stabilizing state‐feedback law with a cascade extended high‐gain observer ...

Jacobsthal Trigonometric Functions

Journal of the Indonesian Mathematical Society
Jacobsthal numbers satisfy a second order homogeneous recurrence relation $J_{n}=J_{n-1}+2J_{n-2}$ where $J_{n}$ denotes the $n^{th}$ Jacobsthal number. In this paper, the Jacobsthal sine, cosine, tangent and cotangent are defined, and some identities of Jacobsthal trigonometric functions are provided.

Photovoltaic Modelling Within the Pan‐European Climate Database v4.2: Capturing PV Diversity for a Climate‐Resilient European Grid

Advanced Energy and Sustainability Research, Volume 7, Issue 5, May 2026.
Pan‐European Climate Database v4.2 was released in 2025 and the methodology behind the new detailed photovoltaic capacity factor timeseries is here described. It highlights typology‐based profiles, with distinctive performance patterns across rooftop and utility‐scale systems, their validation with real TSO data, and their growing role in grid planning,

Moderate Deviation Principles for Lacunary Trigonometric Sums

Mathematische Nachrichten, Volume 299, Issue 5, Page 1028-1044, May 2026.
ABSTRACT Classical works of Kac, Salem, and Zygmund, and Erdős and Gál have shown that lacunary trigonometric sums despite their dependency structure behave in various ways like sums of independent and identically distributed random variables. For instance, they satisfy a central limit theorem (CLT) and a law of the iterated logarithm.

Electrothermal Twisted and Coiled Polymer Artificial Muscles and Their Applications in Soft Robotics

Small Structures, Volume 7, Issue 5, May 2026.
Researchers develop a PE@SPN electrothermal polymer artificial muscle with a parallel‐stranded spiral structure. A temperature self‐sensing‐driven hierarchical closed‐loop fractional order PID (FOPID) control scheme is adopted. A rehabilitation manipulator was designed, and subsequently, a series of experiments are conducted to test the performance of ...

An Engineering Model for Static Yawed Wind Turbines Based on Actuator Line Simulations and Symbolic Regression

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT Yaw engineering models are commonly used as add‐ons to the industrial blade element momentum (BEM) framework to improve load and power predictions by accounting for the skewed wake effect. However, existing yaw engineering models show noticeable limitations in accurately predicting the induced velocity distribution across the blade span.

Wind Turbine Model Validation Is Improved by High‐Resolution, Measurement‐Derived Inflows

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT There is an increased need for accurate validation of turbine models used by original equipment manufacturers to fine‐tune prototypes and predict power performance and maintenance needs while avoiding costly warranty payouts. Perhaps the most substantial source of uncertainty in typical wind turbine model validation procedures is the use of ...
