OBJECTIVE Complete sellar floor reconstruction is critical to avoid postoperative cerebrospinal fluid (CSF) leakage during transsphenoidal surgery. Recently, the pedicled nasoseptal flap has undergone many modifications and eventually proved to be valuable and efficient. However, using these nasoseptal flaps in all patients who undergo transsphenoidal surgery, including those who had none or on...

At CT-RSA 2014, Whitnall, Oswald and Standaert gave the impossibility result that no generic DPA strategies (i.e., without any a priori knowledge about the leakage characteristics) can recover secret information from a physical device by considering an injective target function (e.g., AES and PRESENT S-boxes), and as a remedy, they proposed a slightly relaxed strategy “generic-emulating DPAs” f...

Endoluminal vacuum-assisted closure (E-VAC) is a promising therapy to treat anastomotic leakages of the oesophagus and bowel which are associated with high morbidity and mortality rates. An open-pore polyurethane foam is introduced into the leakage cavity and connected to a device that applies a suction pressure to accelerate the closure of the defect. Computational analysis of this healing pro...

In a recent work from Eurocrypt 2011, Renauld et al. discussed the impact of the increased variability in nanoscale CMOS devices on their evaluation against side-channel attacks. In this paper, we complement this work by analyzing an implementation of the AES S-box, in the DDSLL dual-rail logic style, using the same 65-nanometer technology. For this purpose, we first compare the performance res...

The competitiveness of companies increasingly depends upon whether they possess the cutting-edge or core technology. The technology should be protected from industrial espionage or leakage. A special attention needs to be given to SMB (small and medium business), furthermore, because SMB occupies most of the companies but has serious problems in terms of industrial security. The technology leak...

  The development of transcatheter techniques for treatment of severe mitral valve regurgitation in the beating heart is focus of recent research. An off-pump treatment technique poses great benefits, particularly for multimorbid patients, often being non-compliant to the gold standard treatment, being open heart surgery with use of a cardiopulmonary bypass. Thereto, two approaches are being fo...

BACKGROUND Compared with open esophagectomy (OE), minimally invasive esophagectomy (MIE) proves to have clear benefits in reducing the risk of pulmonary complications for patients with resectable esophageal cancer. The objectives of our study were to explore the superiority of MIE in reducing the occurrence of anastomotic leakages (ALs) when compared to OE. METHODS A systematic review and met...

Side-channel attacks are an important class of attacks against cryptographic devices and profiled side-channel attacks are the most powerful type of side-channel attacks. In this scenario, an adversary first uses a device under his control in order to build a good leakage model. Then, he takes advantage of this leakage model to exploit the actual leakages of a similar target device and perform ...

BACKGROUND Various materials have been added to mineral trioxide aggregate to enhance its properties. This study was aimed to compare the sealing efficacy of MTA with and without nanosilver using bacterial leakage approach. MATERIAL AND METHODS Seventy canine teeth were prepared and obturated. Then, after apical resection, the root-end cavities were prepared by ultrasonic retrotips. Teeth wer...

Motivated by the development of Side-Channel Analysis (SCA) countermeasures which can provide security up to a certain order, defeating higher-order attacks has become amongst the most challenging issues. For instance, Threshold Implementation (TI) which nicely solves the problem of glitches in masked hardware designs is able to avoid firstorder leakages. Hence, its extension to higher orders a...
