Semi-supervised learning (SSL) methods augment standard machine learning (ML) techniques to leverage unlabeled data. SSL techniques are often effective in text classification, where labeled data is scarce but large unlabeled corpora are readily available. However, existing SSL techniques typically require multiple passes over the entirety of the unlabeled data, meaning the techniques are not ap...

Skin surface lipid (SSL) film is a mixture of sebum and keratinocyte membrane lipids, protecting skin from environment. Its composition is unique for the high percentage of long chain fatty acids, and of the polyterpenoid squalene, absent in other human tissues, and in non-human Primates sebum. Here, the still incomplete body of information on SSL as mediators of external chemical, physical, an...

Our proposed method combines semi supervised learning (SSL) and active learning (AL) for automatic detection and segmentation of Crohn's disease (CD) from abdominal magnetic resonance (MR) images. Random forest (RF) classifiers are used due to fast SSL classification and capacity to interpret learned knowledge. Query samples for AL are selected by a novel information density weighted approach u...

Zusammenfassung: Die Akzeptanz und Verbreitung von PKI-Lösungen (Public Key Infrastructure) nimmt in den letzten Jahren zwar zu, ein Durchbruch ist jedoch bisher nicht gelungen. Ein Grund dafür ist das aufwändige und für den Endanwender schwer zu durchschauende Verfahren, um an ein SSL-Zertifikat zu gelangen. Die hohen Sicherheitsanforderungen einer qualifizierten Zertifizierung stehen derzeit ...

As SSL/TLS has become the de facto standard Internet protocol for secure communication in recent years, its security issues have also been intensively studied. Even though several tools have been introduced to help administrators know which SSL/TLS vulnerabilities exist in their network hosts, it is still unclear whether the best security practices are effectively adopted to fix those vulnerabi...

The last couple of years has seen a growing momentum towards using the Internet for conducting business. One of the key enablers for business applications is the ability to setup secure channels across the internet. The Secure Sockets Layer (SSL) protocol provides this capability and it is the most widely used transport layer security protocol. In this paper we investigate the performance of SS...

UNLABELLED The study aimed to identify endogenous lipid mediators of metabolic and inflammatory responses of human keratinocytes to solar UV irradiation. Physiologically relevant doses of solar simulated UVA+UVB were applied to human skin surface lipids (SSL) or to primary cultures of normal human epidermal keratinocytes (NHEK). The decay of photo-sensitive lipid-soluble components, alpha-tocop...

Two genes in an organism have a Synthetic Sickness Lethality (SSL) interaction, if their joint deletion leads to a lower than expected fitness. Synthetic Gene Array (SGA) is a technique that helps in identifying SSL values for pairs of genes in a given set of genes. SSL interactions are useful to discover the co-expressed gene groups in the regulatory and signaling networks. Also, they are used...

M an in the middle attacks are a significant threat to modern e-commerce and online communications, even when such transactions are protected by TLS. We intend to show that it is possible to detect man-in-the-middle attacks on SSL and TLS by detecting timing differences between a standard SSL session and an attack we created.
