It has long been recognized that it can be tedious and even infeasible for system administrators to figure out critical security problems residing in full attack graphs, even for small-sized enterprise networks. Therefore a trade-off between analysis accuracy and efficiency needs to be made to achieve a reasonable balance between completeness of the attack(More)
Because it is not hard to reverse engineer the Dalvik bytecode used in the Dalvik virtual machine, Android application repackaging has become a serious problem. With repackaging, a plagiarist can simply steal others' code violating the intellectual property of the developers. More seriously, after repack-aging, popular apps can become the carriers of(More)
In recent years, as mobile smart device sales grow quickly, the development of mobile applications (apps) keeps accelerating, so does mobile app repackaging. Attackers can easily repackage an app under their own names or embed advertisements to earn pecuniary profits. They can also modify a popular app by inserting malicious payloads into the original app(More)
An app market's vetting process is expected to be scal-able and effective. However, today's vetting mechanisms are slow and less capable of catching new threats. In our research, we found that a more powerful solution can be found by exploiting the way Android malware is constructed and disseminated, which is typically through repackaging legitimate apps(More)
Malignant gliomas represent one of the most aggressive types of cancers and their recurrence is closely linked to acquired therapeutic resistance. A combination of chemotherapy is considered a promising therapeutic model in overcoming therapeutic resistance and enhancing treatment efficacy. Herein, we show by colony formation, Hochest 33342 and TUNEL(More)
In its latest comparison of Android Virus Detectors (AVDs), the independent lab AV-TEST reports that they have around 95% malware detection rate. This only indicates that current AVDs on Android have good malware signature databases. When the AVDs are deployed on the fast-evolving mobile system, their effectiveness should also be measured on their runtime(More)
Autophagy is a genetically programmed, evolutionarily conserved intracellular degradation pathway involved in the trafficking of long-lived proteins and cellular organelles to the lysosome for degradation to maintain cellular homeostasis. Alcohol consumption leads to injury in various tissues and organs including liver, pancreas, heart, brain, and muscle.(More)
The accumulation of glomerular extracellular matrix (ECM) is one of the critical pathological characteristics of diabetic renal fibrosis. Fibronectin (FN) is an important constituent of ECM. Our previous studies indicate that the activation of the sphingosine kinase 1 (SphK1)-sphingosine 1- phosphate (S1P) signaling pathway plays a key regulatory role in FN(More)
The Android OS not only dominates 78.6% of the worldwide smartphone market in 2014, but importantly has been widely used for mission critical tasks (e.g., medical devices, auto/aircraft navigators, embedded in satellite project). The core of Android, System Server (SS), is a multi-threaded process that contains most of the system services and provides the(More)
Alzheimer's disease (AD) is characterized by the dysfunction or loss of a vulnerable group of neurons. At present, only a few options exist for treating neurodegenerative diseases effectively. Advances in stem cell research have raised the hope and possibility for therapy in neurodegenerative diseases. In AD transgenic animal models, stem cell(More)
