CESNET-QUIC22: A large one-month QUIC network traffic dataset from backbone lines.

The QUIC (Quick UDP Internet Connection) protocol has the potential to replace TLS over TCP, which is the standard choice for reliable and secure Internet communication. Due to its design that makes the inspection of QUIC handshakes challenging and its usage in HTTP/3, there is an increasing demand for research in QUIC traffic analysis. This dataset contains one month of QUIC traffic collected in an ISP backbone network, which connects 500 large institutions and serves around half a million people. The data are delivered as enriched flows that can be useful for various network monitoring tasks. The provided server names and packet-level information allow research in the encrypted traffic classification area. Moreover, included QUIC versions and user agents (smartphone, web browser, and operating system identifiers) provide information for large-scale QUIC deployment studies.

Collection of datasets with DNS over HTTPS traffic.

Recently, the Internet has adopted the DNS over HTTPS (DoH) resolution mechanism for privacy-aware network applications. As DoH becomes more disseminated, it has also become a network monitoring research topic. For comprehensive evaluation and comparison of developed classifiers, real-world datasets are needed, motivating this contribution. We created a new large-scale collection of datasets consisting of two classes of traffic: i) DoH HTTPS communication and ii) non-DoH HTTPS connections. The DoH traffic is captured for multiple DoH providers and clients to include nuances of various DoH implementations and configurations. The non-DoH HTTPS connections complement the DoH communication aiming to include a wide range of existing network applications. The dataset collection consists of network traffic generated in a controlled environment and traffic captured from a real ISP network. The resulting datasets thus provide real-world network traffic data suitable for evaluating existing classifiers and the development of new methods.

Depression, prolactin and dissociated mind.

OBJECTIVES: Usual neuroendocrinological manifestation of traumatic stress and dissociation is dysregulation of the hypothalamus-pituitary-adrenal (HPA) axis. The aim of the present study is to perform examination of HPA axis as indexed by basal serum prolactin and test its relationship to dissociative symptoms and symptoms of traumatic stress. PATIENTS AND METHODS: 25 inpatients treated at the university hospital with diagnosis of unipolar depression mean age 41.23 (SD=11.53) were assessed using psychometric measures of dissociation (DES) and traumatic symptoms (TSC-40), and using standard biochemical analytical methods basal serum prolactin levels were investigated. RESULTS: Data show that prolactin manifests significant relationship to dissociative symptoms (r=0.52, p=0.004). Significant correlation was not found between prolactin and traumatic symptoms measured by TSC-40 (r=0.31, p=0.07). CONCLUSIONS: The present data suggest that serum prolactin levels in unipolar depressive patients are related to dissociative symptoms that is likely caused by passive coping mechanisms leading to dissociation.

Depression, traumatic dissociation and epileptic-like phenomena.

OBJECTIVES: According to recent findings trauma and stress are important etiological factors in pathogenesis of depression. As characteristic features of depressive cognition have been reported intrusive thoughts and memory disturbances similar to posttraumatic symptoms known in patients with posttraumatic stress disorder or dissociative disorders. Hypothetically is also suggested a close relationship of traumatic dissociation and epileptic-like phenomena. SETTINGS AND DESIGN: In the clinical study were assessed 70 adult people with a diagnosis of depression and 50 healthy controls. In the assessment were used 6 measures for symptoms of dissociation, depression, traumatic stress and psychosenzoric symptoms of epileptic origin (the so-called complex partial seizure-like symptoms). RESULTS: Reported data show that a great number of depressive patients who met the cut-off score for dissociative disorders (34.2%, N=24) had significantly higher traumatization, depression, subjectively experienced stress and complex partial seizure-like symptoms than the whole group of patients and the controls. Most significant traumatization has been found in patients who met the cut-off score of psychosenzoric epileptic-like symptoms which is characteristic for the epilepsy spectrum disorder (5.7%, N=4). MAIN FINDINGS: Significant correlations of these assessed symptoms suggest close relationship between traumatic stress and dissociation in depression. This close relationship of dissociative symptomatology and traumatic stress also implicates an important role of dissociative processes in depression as a typical manifestation of depressive cognition. Assessed relationship between traumatic distress and complex partial seizure-like symptoms suggests a possible role of epileptic-like phenomena in dissociative states related to depression. CONCLUSIONS: Assessed relationship between traumatization, depression and epileptic-like phenomena in the patients who met cut-off score for epilepsy spectrum disorder can contribute to the problem of indication of several depressive patients to anticonvulsant therapy because of reported evidence that a clear majority of patients with epilepsy spectrum disorder respond well to anticonvulsant treatment. Careful assessment of this test battery thus may be useful also for anticonvulsant treatment strategy.
