Investigation on the structural, magnetic, magnetocaloric and magnetotransport behaviour of LaSrMnO manganites synthesised by different routes.

In the present investigation, we present the comparison of the structural, magnetic, magnetocaloric and magnetoresistance behavior of solid state and sol-gel derived LaSrMnO. X-ray diffraction together with Rietveld refinement confirms the rhombohedral structure of the synthesised samples with the 3̄ space group. The ferromagnetic-to-paramagnetic transition temperature decreases from 360 K to 346 K for the nanocrystalline sample.

Evaluation of the efficacy of TruNatomy, ProTaper retreatment, and RaCe file systems in retreatment of moderately curved mandibular molars: An study.

Context: Endodontic retreatment is the first line of treatment in cases of failed primary endodontic treatment. Although associated with challenges such as incomplete removal of obturating material, increased clinical time, and extrusion of apical debris, endodontic retreatment still has considerable success rate in the general population.

Aims: The aim of this study was to evaluate and compare the efficacy of TruNatomy, ProTaper retreatment, and RaCe file systems to remove the obturating material, time taken to remove the obturating material, and apical extrusion of debris using cone-beam computed tomography (CBCT).

Management of Non-union Distal Femur Fractures With Augmentation Nail Plate Construct.

Background and objective A non-union distal femur fracture is a challenging fracture to treat. Common treatment modalities for non-union distal femur fractures include dual plating, intramedullary nails, ilizarov, and hybrid fixators. Despite the availability of a wide armamentarium of constructs, the clinical and functional outcome of these modalities is often complicated by significant morbidity, joint stiffness, and delayed union.

Buttress Plate Assisted Fixation for Bicondylar Hoffa Fracture: A Missed Fracture-case Report with Review of Literature.

Introduction: Bicondylar Hoffa fractures are extremely uncommon injuries and there have only been a very small number of cases documented in the literature.

Case Report: A 28-year-old male presented to emergency department with injury to right knee and leg. X-ray was taken; however, they were not sufficient to determine the precise fracture pattern, so computed tomography scan was done for establishing diagnosis.

Reachability Deficits in Quantum Approximate Optimization.

The quantum approximate optimization algorithm (QAOA) has rapidly become a cornerstone of contemporary quantum algorithm development. Despite a growing range of applications, only a few results have been developed towards understanding the algorithm's ultimate limitations. Here we report that QAOA exhibits a strong dependence on a problem instances constraint to variable ratio-this problem density places a limiting restriction on the algorithms capacity to minimize a corresponding objective function (and hence solve optimization problem instances).
