Autologous Cancellous Bone Interposition to Enhance Tendon‐Bone Integration in Hamstring Tendon Anterior Cruciate Ligament Reconstruction: A Surgical Technique

Arthroscopy Techniques, EarlyView.
Abstract Hamstring tendon autografts remain a popular choice for anterior cruciate ligament reconstruction due to their favorable biomechanical properties and reduced donor‐site morbidity; however, delayed tendon‐to–bone integration and tunnel widening continue to limit outcomes when compared with bone–patellar tendon–bone grafts.

TreeMig framework ver. 1.0: an R package with GUI to simulate spatio‐temporal forest dynamics

Ecography, EarlyView.
Spatio‐temporal vegetation models are essential for simulating dynamics and shifts in species distributions over large areas, particularly under global change. One such model is the dynamic forest landscape model TreeMig. We have developed a framework that makes the model more user‐friendly, improves its functionality, and expands its possibilities ...

MIMO free-space optical communication employing subcarrier intensity modulation in atmospheric turbulence channels

, 2009
In this paper, we analyse the error performance of transmitter/receiver array free-space optical (FSO) communication system employing binary phase shift keying (BPSK) subcarrier intensity modulation (SIM) in clear but turbulent atmospheric channel ...

Liquid Crystal Polymers as Intrinsically Magnetic and Programmable Soft Materials for Microrobotics

Small, EarlyView.
Liquid crystal polymers (LCPs) are proposed as intrinsically magnetic, programmable, soft materials for microrobotics. Magnetic torque‐driven manipulation of LCP microobjects is achieved and characterized in terms of the step‐out frequency, reaching ∼0.6 Hz in a ∼250 mT magnetic field. The orientation of LCP microobjects in the magnetic field and their

St John's Wort (Hypericum perforatum) Oil on Immune Response, Growth Performance and Bacterial Resistance Against Lactococcus garvieae Pathogen in Rainbow Trout (Oncorhynchus mykiss)

Journal of Fish Diseases, EarlyView.
ABSTRACT In this study, we investigated the immunomodulatory effects of St. John's Wort (Hypericum perforatum) oil on the growth performance, immune responses and resistance against Lactococcus garvieae in rainbow trout (Oncorhynchus mykiss). The plant oil was incorporated into feeds at concentrations of 1, 3, and 5 g kg−1, designated as K1, K3, and K5,
