The Effect of the Gem‐Dimethyl Unit in the Gold‐Catalyzed Cycloisomerization of Aliphatic 1‐Bromoalkynes

European Journal of Organic Chemistry, EarlyView.
The conformational effect of the gem‐dimethyl motif and its isostere cyclopropane unit in the gold‐catalyzed cycloisomerization of aliphatic 1‐bromoalkynes has been studied. An unexpected inhibitory effect of the cyclopropane ring has been observed.

The Reluctance of Some Irregular Magnetic Fields

Transactions of the American Institute of Electrical Engineers, 1915
The development of the idea of magnetic reluctance is sketched, and the mathematical and experimental methods of determining it are first discussed. On the theoretical side it is the theory of complex quantities which leads to numerical results. The electric field of an electric generator is next analyzed and made to depend approximately upon the ...

Pseudoaneurysms as a complication of stereoelectroencephalography: Case series and clinical recommendations

Epilepsia, EarlyView.
Abstract Objective Stereoelectroencephalography (sEEG) is commonly employed in the workup for epilepsy surgery in patients with focal drug‐resistant epilepsy (DRE). Intracranial hemorrhage is a known complication, with reported incidence rates ranging from .9% to 19.1%. Rarely, pseudoaneurysms have been reported in literature as a potential cause. This

Optimization of Energy Efficiency in Photovoltaic Water Pumping Systems Using Neural Networks

Energy Science &Engineering, EarlyView.
This study investigates an optimal control strategy for a photovoltaic (PV) water pumping system aimed at improving efficiency and autonomy in off‐grid applications. The system uses an induction motor with direct torque control and compares three maximum power point tracking (MPPT) techniques: neural network–based MPPT, Incremental Conductance (IC ...

Approaches to Computed Tomography Education for Radiography Students

Journal of Medical Radiation Sciences, EarlyView.
The aim of this narrative review was to explore the current published literature relating to CT teaching methods and assessment of diagnostic radiography students during university training. Existing CT education evaluations focus on student satisfaction and usability of tools, with post‐lesson knowledge gains reported. Future work should shift towards
