In distributed systems, the smart card based password authentication, as one of the most convenient and efficient two-factor authentication mechanisms, is widely used to ensure that the protected services are not available to unauthorized users. Recently, Li et al. demonstrated that the smart card based password authentication scheme proposed by Chen et al. cannot provide perfect forward secrec...

Objectives: Among a subgroup of participants in the Strategies for Management of Antiretroviral Therapy (SMART) Trial that were naı̈ve to antiretroviral therapy (ART) or off ART (6 months or longer) at study entry, risk of AIDS and serious non-AIDS events were increased for participants who deferred ART compared with those randomized to (re)initiate ART immediately. Our objective was to determin...

For diagnosing radiation optic neuropathy (RON) ophthalmological and imaging data were evaluated from 63 acromegalic patients, irradiated between 1967 and 1998. Two patients developed RON: one patient in one optic nerve 10 years and another patient in both optic nerves 5 months after radiation therapy. RON is a rare complication after external beam radiation therapy for acromegaly, which can oc...

PURPOSE To evaluate the influence of timing of salvage and adjuvant radiation therapy on outcomes after prostatectomy for prostate cancer. METHODS Using the Surveillance, Epidemiology, and End Results-Medicare linked database, we identified prostate cancer patients diagnosed during 1995-2007 who had one or more adverse pathological features after prostatectomy. The final cohort of 6,137 eligi...

For a safe and reliable operation of the smart grid, timely detection of cyber-attacks is of critical importance. Moreover, considering smarter and more capable attackers, robust detection mechanisms are needed against a diverse range of cyber-attacks. With these purposes, we propose a robust online detection algorithm for (possibly combined) false data injection (FDI) and jamming attacks, that...

In 2004 and 2005, Tsaur et al. proposed a smart card based password authentication schemes for multi-server environments, respectively. They claimed that their protocols are safe and can withstand various kinds of attacks. However, after analysis, we found their schemes each have some secure loopholes. In this article, we will show the security flaws in these two protocols.

BACKGROUND Radiation maculopathy is a phenomenon that occurs after radiation exposure. The rapid onset of unilateral macular atrophy without peripheral retinopathy after radiation has rarely been described. METHODS A case report and literature review. RESULTS We report a case of stage 4 non-small cell lung cancer under targeted therapy using Gefitinib who presented with severely impaired vi...

On Crypto ’88, Matsumoto, Kato, and Imai presented protocols to speed up secret computations with insecure auxiliary devices. The two most important protocols enable a smart card to compute the secret RSA operation faster with the help of a server that is not necessarily trusted by the card holder. It was stated that if RSA is secure, the protocols could only be broken by exhaustive search in c...

AIM To evaluate the use of scatter laser photocoagulation to prevent radiation related retinopathy, maculopathy, and loss of vision. METHODS This was an interventional case series. 66 eyes with posterior choroidal melanomas treated by ophthalmic plaque radiation therapy were reported. Of these patients, 50 were selected because they developed radiation retinopathy; 45 of these were treated wi...

Extra renal extra cranial malignant rhobdoid tumors (MRT) are rare, frequently lethal and affect mostly children. No definite treatment has been made and the role of radiation therapy is poorly defined. This report explains a 14 year old girl with MRT in her neck soft tissue. She is alive with no evidence of disease 18 months after diagnosis. Through the experience with this case, we suggested...
