Sentiment classification for insider threat identification using metaheuristic optimized machine learning classifiers.

This study examines the formidable and complex challenge of insider threats to organizational security, addressing risks such as ransomware incidents, data breaches, and extortion attempts. The research involves six experiments utilizing email, HTTP, and file content data. To combat insider threats, emerging Natural Language Processing techniques are employed in conjunction with powerful Machine Learning classifiers, specifically XGBoost and AdaBoost.

The most common deviations in the development of hand motoricity in children from birth to one year of age.

The early child development, from birth until the age of one year is, amongst other changes, characterized by intense motor learning. During that period, the voluntary learning patterns evolve from reflexive patterns to coordinated voluntary patterns. All of the child's voluntary movements present active forms in which the child communicates with the environment.

Overview of 100 patients with voice prosthesis after total laryngectomy--experience of single institution.

Surgical procedures, especially total laryngectomy, used for treatment of advanced laryngeal carcinoma, have a profound adverse effect on the patient's physical, functional, and emotional health, and almost always decrease quality of life. There are three main types of voice rehabilitation after surgery. They are: esophageal speech techniques, the use of artificial larynx devices and tracheoesophageal puncture with the insertion of various types of voice prostheses.

[Parathyroid carcinoma].

Background: Parathyroid carcinoma is the least frequent malignancy among endocrine tumors. In the most reported series of patients with primary hyperparathyroidism the incidence of carcinoma is less than 1%. Racognition by a surgeon that the parathyroid tumor is malignant, and the performance of an adequate en bloc removal of primary lesion, with histologic diagnosis offer the best treatment of a patient with this unusual malignancy.
