Mobile phone sensing provides a promising paradigm for collecting data and has been receiving increasing attention in recent years. Different from most existing works, which protect participants' privacy by hiding the content of their allow aggregator to compute some simple aggregation functions, we propose new approach delinking its sources. This allows get exact distribution and, therefore, enables efficiently arbitrary/complicated functions. In particular, first present an efficient...

Triple-negative breast cancers (TNBCs), devoid of hormone receptors and human epidermal growth-factor receptor-2/Neu expression, bring about poor prognosis induce a high rate systematic metastases. The ineffectiveness current therapies on TNBCs could be attributed to the lack efficient targeted therapy. Paclitaxel (PTX) is considered one first-line chemotherapeutics for TNBC treatment but, due its low aqueous solubility nonspecific accumulation, results in antitumor efficacy. present study...

Protecting the privacy of mobile phone user participants is extremely important for sensing applications. In this paper, we study how an aggregator can expeditiously compute minimum value or kth all users' data without knowing them. We construct two secure protocols using probabilistic coding schemes and a cipher system that allows homomorphic bitwise XOR computations our problems. Following standard cryptographic security definition in semi-honest model, formally prove protocols' security....

In microservice systems, the identification of root causes anomalies is imperative for service reliability and business impact. This process typically divided into two phases: (i)constructing a dependency graph that outlines sequence structure system components are invoked, (ii) localizing cause using graph, traces, logs, Key Performance Indicators (KPIs) such as latency. However, both phases not straightforward due to highly dynamic complex nature system, particularly in large-scale...

Today's large-scale enterprise networks, data center and wide area networks can be decomposed into multiple administrative or geographical domains. Domains may owned by different units organizations. Hence protecting domain information is an important concern. Existing general-purpose Secure Multi-Party Computation (SMPC) methods that preserves privacy for domains are extremely slow cross-domain routing problems. In this paper we present PYCRO, a cryptographic protocol specifically designed...

The 4-dose Essen intramuscular (IM) regimen for rabies post-exposure prophylaxis (PEP) has been recommended by Advisory Committee on Immunization Practices (ACIP) and World Health Organization (WHO), but the large-sample clinical evidence is still limited. Rabies virus neutralizing antibodies of 11,752 patients were detected from 409 prevention clinics in 27 provinces China. Patients with serum collected before or no later than 1 h after injection day fifth dose (day 28) 5-dose included...

Rabies is a fatal zoonotic infectious disease primarily caused by the rabies virus. Anti-rabies monoclonal antibody (mAb) developed using modern genetic engineering technology. However, no bibliometric assessment has been conducted to evaluate scientific progress in this area. A search of articles Web Science (WoS) from January 1, 1991, November 17, 2024, yielded 455 papers that were analyzed various online analysis tools. The cumulative publications 1991 2023 followed linear distribution....
