The rapid increase in new malware necessitates effective detection methods. While machine learning techniques have shown promise for malware detection, most research focuses on identifying malware through the content of executable files or full behavior logs collected from process start to finish. However, detecting threats like ransomware via full logs is redundant, as this malware type openly informs users of the infection.

Organizations prepare against cyber attacks by creating Cyber Security Incident Response Teams (CSIRTs) that use various technologies to monitor and detect threats and to help perform forensics on machines and networks. Testing the limits of defense technologies and the skill of a CSIRT can be performed through adversary emulation performed by so-called "red teams".

Malicious processes may try to hide by changing the behavior of other benign processes to achieve their goals. We showcase how Component Object Model (COM) and Windows Management Instrumentation (WMI) can be used to create such spoofing attacks.

A key feature of this metric is its ability to ensure network resilience against disruptions by effectively utilizing redundant paths in the network. This makes the metric an indispensable tool for field engineers in both the design and deployment of wireless sensor networks.

Artificial intelligence (AI) might provide an efficient solution for the automatic diagnosis of EMD by improving the subjective interpretation of HREM images. The aim of our study was to develop an AI-based system, using neural networks, for the automatic diagnosis of HREM images, based on one wet swallow raw image.

Methods: A prospective, investigational, real-world study was performed from April 2020 to April 2021 at our center. COVID-19 severity was classified by World Health Organization criteria, and cytokine storm was documented along predefined criteria.
The goal of this paper is to provide a Machine Learning-based solution that can be utilized to automate the Chicago Classification algorithm, the state-of-the-art scheme for esophageal motility disease identification. First, the photos were preprocessed by locating the area of interest-the precise instant of swallowing. After resizing and rescaling the photos, they were utilized as input for the Deep Learning models.

Color pressure topography plots are generated and analyzed and using the Chicago algorithm a final diagnosis is established. One of the main parameters in this algorithm is integrated relaxation pressure (IRP).

The identification of functional networks involved in complex brain functions, including visuospatial abilities (VSAs), is usually difficult. We report our preliminary experience using a preoperative planning based on the combination of navigated transcranial magnetic stimulation (nTMS) and DTI tractography to provide the preoperative 3D reconstruction of the visuospatial (VS) cortico-subcortical network in patients with right parietal lobe tumors.

Our case is a proven right-handed, 30-year-old female patient with a low-grade glioma, which was located in the temporo-opercular region and also in the superior temporal gyrus of the right hemisphere. Upon presurgical planning, the motor, language, and visuospatial functions were mapped.

There is an urgent need to look for alternative strategies for COVID-19 treatment especially in the case of severe and/or critically ill patients with cytokine release syndrome (CRS).
Aim: Convalescent plasma proved to increase survival rates in other severe viral infections.
The rapidly evolving field of repetitive transcranial magnetic stimulation as a neuromodulational technique may mean a safe, alternative approach to the management of several mental disorders, especially treatment-resistant major depressive disorder. Our aim is to describe the current role of transcranial magnetic stimulation in research and routine clinical practice, based on the literature and clinical protocols. Since the discovery, that an outer magnetic source can depolarize neurons, both neurology and psychiatry seek the method's possible clinical utility.

Methods: A 23-item questionnaire was administered to 66 interns before and after watching ECT.
Background: The diagnostic distribution of patients treated with electroconvulsive therapy (ECT) in Hungary is significantly different from that in Western Europe or the USA. In Hungary most of the treated patients are diagnosed with schizophrenia.
Aim: To analyze the practice of referring patients for ECT in Hungary.
"Avemar pulvis" is a powder consisting of an aqueous extract of fermented wheat germ, with the drying aids maltodextrin and silicon dioxide, standardized to contain approximately 200 microg/g of the natural constituent 2,6-dimethoxy-p-benzoquinone. The results of toxicological and clinical studies of this product demonstrate its safety for its intended use as a dietary supplement ingredient in the United States. Avemar pulvis has been used in Hungary since 1998 and is approved in that country, as well as in the Czech Republic, Bulgaria, and Romania, as a "medical nutriment for cancer patients.

Lack of cooperation can cause difficulties in the examinations, during the invasive interventions following the diagnostic process, and also in the pharmacological treatment. Among the reasons leading to noncompliance, psychiatric disorders concomitant with somatic disturbances play a major role.

Several studies have shown that comorbid dementia increases the length of stay (LOS) in hospitals. The literature is more contradictory in the case of anxiety disorders, substance-related disorders, mood disorders and delirium.

Unlabelled: The most effective way for the diagnosing and the treatment of psychopathological symptoms appearing in non-psychiatric hospitalized patients is the utilization of consultation-liaison psychiatry. With the increasing number of the elderly patients, number of appearing gerontopsychiatric problems in consultation work is also growing.
Aim: We have studied among the patients of a consultation-liaison service the problems which led to the psychiatric consultations, the diagnoses which were set up, the concomitant somatic disorders and the treatment recommendations.

The design enabled us to record the brain activity engaged during spatial shifts of covert attention that was independent from the physical characteristics of the cueing stimulus using event-related potentials (ERPs). ERPs elicited by foveal cues differed according to the predicted target location starting ca.

Epidural event related potentials (ERPs) were recorded from four squirrel monkeys (Saimiri sciureus) during the presentation of pictoral stimuli that comprised real human and monkey faces. Subjects viewed tachistoscopically presented stimuli belonging to four different categories: familiar and unfamiliar human faces, and familiar and unfamiliar monkey faces. Familiar faces were subcategorized into top, middle and bottom according to the perceived individual's dominance ranking in a social hierarchy, as rated by human judges observing the group's social behavior.
