Several off-the-shelf products enable network operators to enforce usage restrictions by actively terminating connections when deemed undesirable. While the spectrum of their application is large—from ISPs limiting the usage of P2P applications to the “Great Firewall of China”—many of these systems implement the same approach to disrupt the communication: they inject artificial TCP Reset (RST) ...

Image manipulation is not a new trend and it exists from the time when photography was innovated. In the recent years, many forgery detection methods and techniques are proposed. Photo image forgery may include Copy-Move Forgery or Cloning and Copy-Create Image Forgery. There are few methods for forgery detection. Though many image forgery detections previously exist, with the change in algorit...

In 2003, Shen et al. proposed an improvement on YangShieh’s timestamp-based password authentication scheme using smart cards. Then they claimed that their scheme cannot withstand a forged login attack, but also eliminate a problem of Yang-Shieh’s. However, their scheme is still susceptible to forged login attack. In this letter, we show how the forged login attack can be worked out on Shen et a...

The email system is the central battleground against phishing and social engineering attacks, and yet email providers still face key challenges to authenticate incoming emails. As a result, attackers can apply spoofing techniques to impersonate a trusted entity to conduct highly deceptive phishing attacks. In this work, we study email spoofing to answer three key questions: (1) How do email pro...

Accurate prediction of neurological outcome in survivors of cardiac arrest may be difficult. We report the case of a 44-year-old survivor of a hypoxic cardiac arrest who repeatedly developed relentless myoclonic jerks on attempted discontinuation of his propofol infusion. These were initially thought to represent myoclonic status epilepticus before the correct diagnosis of Lance-Adams syndrome ...

OBJECTIVES To determine whether skin-to-skin contact between mothers and their newborns will reduce the pain experienced by the infant during heel lance. DESIGN A prospective, randomized, controlled trial. SETTING Boston Medical Center, Boston, Massachusetts. PARTICIPANTS A total of 30 newborn infants were studied. INTERVENTIONS Infants were assigned randomly to either being held by the...

The acoustic lance is an instrument developed to obtain in situ compressional wave velocity and attenuation ~Q! profiles for a sedimentary layer of several meters thickness at the sediment– seawater interface. The self-contained instrument consists of ten independent recording channels with a linear array of receivers embedded in the seafloor below a broadband acoustic source. It provides in si...
