Ternary Mg–Y–Zn alloys have attracted considerable attention due to their excellent mechanical properties and unique microstructures. Microstructural variation and the resulting mechanical properties can be affected by various processing routes, particularly those involving severe plastic deformation of a cast billet. The following approach was used in this work to perform a comparative study: ...

Sir, Progressive image technologies are improving the accuracy for determining the localization of enlarged parathyroid glands (PTGs) in hyperparathyroidism (HPT). However, the identification of an unusually located cervical nodule as an ectopic PTG remains uncertain. The measurement of parathyroid hormone (PTH) in the aspirated material with a fine needle has shed light on this diagnostic diff...

The study of the fundamentals ? ? ? and ? phase transformations induced by high-pressure torsion (HPT) in Ti–Nb-based alloys is presented current work. Prior to HPT, three with 5, 10, 20 wt% Nb were annealed temperature range 700–540°C order obtain (? + ?)-phase state a different amount ?-phase. samples for long time reach equilibrium content ?-solid solution. Scanning electron microscope (SEM)...

An important aspect of machine learning (ML) involves controlling the process for ML method in question to maximize its performance. Hyperparameter tuning (HPT) selecting suitable parameters that control process. Given HPT can be conceptualized as a black box optimization problem subject stochasticity, simulation (SO) methods appear well suited this purpose. Therefore, we conceptualize discrete...

The Hybrid Phenomena Theory (HPT) is a framework for formalizing how dynamic state space models of physical systems are built from first principles. The HPT descends from the Qualitative Process Theory (QPT), [Forb us, 1984], from which it inherits basic concepts like views, phenomena and influences. However, the HPT redefines some of these concepts in a more strict manner in order to represent...

A cortical lesion of the tibial diaphysis in a young patient poses a diagnostic challenge to the clinician. Brown tumors, although not very common, may mimic malignancies on radiographs. Brown tumors are destructive lytic lesions of the bone due to increased osteoclastic activity and fibroblastic proliferation in patients with uncontrolled hyperparathyroidism (HPT). They occur after primary or ...

Obesity is a major public health issue worldwide. Current pharmacological treatments are largely unsuccessful. Determining the complex pathways that regulate food intake may aid the development of new treatments. The hypothalamic-pituitary-thyroid (HPT) axis has well-known effects on energy expenditure, but its role in the regulation of food intake is less well characterised. Evidence suggests ...

Although nano/microsatellites have great potential as remote sensing platforms, the spatial and spectral resolutions of an optical payload instrument are limited. In this study, a high spatial resolution multispectral sensor, the High-Precision Telescope (HPT), was developed for the RISING-2 microsatellite. The HPT has four image sensors: three in the visible region of the spectrum used for the...

The hypercalcemia of hyperparathyroidism (HPT) can cause devastating effects to the patient and only surgical removal of the hyperfunctioning parathyroid tissue can definitely cure the disease. Radionuclide parathyroid imaging has no role in the diagnosis of hyperparathyroidism or in the selection of the type of treatment. However, once surgery is decided (99m)Tc-sestamibi scanning can localize...
