Currently, no reliable noninvasive methods exist for monitoring the severity of in vivo cyanide (CN) toxicity, treatment, and resulting physiological changes. We developed a broadband diffuse optical spectroscopy (DOS) system to measure bulk tissue absorption and scattering. DOS was used to optically monitor CN toxicity and treatment with sodium nitrite (NaNO2). To perform experiments, the DOS ...

Wireless sensors are very small embedded devices with low memory, low computing power and low battery life. Various applications such as continuous connectivity, weather monitoring, industry and instantly -deployable communication for first responders and armed. These networks already consider environmental conditions, factory performance, and troop deployment, to name some applications. Wirele...

Denial of Service (DoS) attacks are an increasing problem for network connected systems. Key establishment protocols are applications that are particularly vulnerable to DoS attack as they are typically required to perform computationally expensive cryptographic operations in order to authenticate the protocol initiator and to generate the cryptographic keying material that will subsequently be...

|Key-agreement protocol will play an important role as an entrance to secure communication over the Internet. Speci cally, ISAKMP(Internet Security Association and Key Management Protocol)/Oakley key-agreement is currently a leading approach for communication between two parties. Basic idea of ISAKMP/Oakley is an authenticated Di eHellman (DH) key-agreement protocol. This authentication owes a ...

PURPOSE Diffuse optical spectroscopy (DOS) has the potential to enable monitoring of tumor response during chemotherapy, particularly in the early stages of treatment. This study aims to assess feasibility of DOS for monitoring treatment response in HER2-negative breast cancer patients receiving neoadjuvant chemotherapy (NAC) and compare DOS with tumor response assessment by MRI. EXPERIMENTAL...

Denial-of-service (DoS) attacks have become a major threat to current systems and networks in the Internet. Yet the existing infrastructure is rarely tested for potential damage caused by (D)DoS attacks because no method exist to audit a productive system without flooding and thus risking system outages and resulting losses. Having a method that does (D)DoS attack auditing without requiring the...

INTRODUCTION Destructive ocular surgery (DOS) means eye loss. An audit of its indications would be useful in reducing its incidence. OBJECTIVE To determine indications for destructive ocular surgeries. MATERIALS AND METHODS The case records (files) of all the patients who had DOS in a tertiary health facility in Nigeria from January 2004 to December 2011 were reviewed retrospectively. The i...

OBJECTIVE To better characterize cumulus-oocyte interactions during oocyte maturation and fertilization in the cat model. DESIGN Experimental in vitro study. SETTING Smithsonian Institution. ANIMAL(S) Domestic shorthair cats. INTERVENTION(S) Groups of denuded oocytes (DOs) and cumulus-oocyte complexes (COCs) were subjected to in vitro maturation (with or without FSH and LH, with or with...

Resumo: Muitas anomalias e doenças genéticas podem ser descobertas através da análise da forma e das características morfológicas dos cromossomos. Para alcançar este objetivo, geralmente constrói-se o cariótipo, a partir de uma fotografia obtida através de um microscópio, através da organização e ordenação dos cromossomos de uma célula humana de acordo com o seu tamanho. Apesar dos grandes avan...
