Optimizing system resilience is concerned with the development of strategies to restore a system to normal operations as quickly and efficiently as possible following potential disruption. To this end, we present in this article a bilevel mixed integer linear program for protecting an uncapacitated median type facility network against worstcase losses, taking into account the role of facility r...

OBJECTIVE This in vitro study aimed to analyse the protective effect of differently concentrated titanium (TiF(4)), zirconium (ZrF(4)) and hafnium (HfF(4)) tetrafluoride on enamel erosion. METHODS Polished enamel surfaces of 36 bovine crowns were covered with tape leaving 4 enamel windows each 3mm in diameter exposed. The crowns were randomly assigned to six groups (each n=6) and pretreated w...

this paper is concerned with development of a technique for performance prediction of current transformers (ct), accurately. in this technique, a new optimized model from view-point of both computation time and memory is introduced in order to simulate the current transformers on digital computers. the introduced software in this paper in combination with relay tester equipments can be used ins...

Sulfadoxine-pyrimethamine (SP) has been one of the most widely used antimalarial treatments world-wide, and is also used prophylactically in vulnerable populations. In this paper, we develop a mathematical model which allows us to infer the time distribution of SP protection from drug-trial data. Fitting our model to data from a controlled field study in Mali, we find that SP provided protectio...

A DTW-based biometric user authentication system needs a DTW template to set up a warping function for a query biometric. In addition, a matching template is required to examine similarity. In this paper, we present a hardened template to protect the DTW template. For the matching template, it is protected by cryptographic framework. We compare our scheme with a transformation approach and an u...

We present five studies supporting our strategic memory protection theory. When people make decisions about experiences to consume over time, they treat their memories of previous experiences as assets to be protected. The first two studies demonstrate that people tend to avoid situations that they believe will threaten their ability to retrieve special (rather than merely pleasant) memories. T...

Ransomware is a form of extortion-based attack that locks the victim’s digital resources and requests money to release them. The recent resurgence of high-profile ransomware attacks, particularly in critical sectors such as the health care industry, has highlighted the pressing need for effective defenses. While users are always advised to have a reliable backup strategy, the growing number of ...

Recent studies have indicated that type 2 cannabinoid receptor (CB2R) agonists reduce neurodegeneration after brain injury through anti-inflammatory activity. The purpose of this study was to examine the time-dependent interaction of CB2R and inflammation in stroke brain. Adult male rats were subjected to right middle cerebral artery occlusion (MCAo). CB2R mRNA expression was significantly elev...

The aim of this study was to determine the most optimal heating time in protection of protein rich feedstuff on digestibility and in vitro ruminal fermentation profile. Proteinous feedstuffs used in this study is soybean meal (Glycine max). This study is designed using one way ANOVA, with five treatments of heating time (T0 (control)= unheated, T1= 10 min, T2= 20 min, T3= 30 m...
