On Quasi-thin Association Schemes
Journal of Combinatorial Theory, Series A, 2002 An association scheme is called quasi-thin if each of its basic relations has valency 1 or 2. In this paper three sufficient conditions for a quasi-thin scheme \((X,R)\) to have an automorphism group acting transitively on \(X\) are obtained: (i) \(O^\theta(R)\cap O_\theta(R)=\{1\}\) (Lemma 4.1), (ii) \(n_{O^\theta(R)}=2\) (Theorem 4.4), and (iii) \(R\)

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

Pediatric Blood &Cancer, EarlyView.ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...

Fog-aided identity privacy protection scheme for sensing users in mobile crowd sensing
网络与信息安全学报, 2019 In mobile crowd sensing(MCS), attackers can reconstruct the social circle among sensing users, who use the social association information among sensing users and the correlation between the sensing user’s identity and sensing data to further attack a ...

Millimeter-Wave Interference Avoidance via Building-Aware Associations
IEEE Access, 2018 Signal occlusion by building blockages is a double-edged sword for the performance of millimeter-wave (mmW) communication networks. Buildings may dominantly attenuate the useful signals, especially when mmW base stations (BSs) are sparsely deployed ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with

Multilevel Association Rule Mining for Bridge Resource Management Based on Immune Genetic Algorithm
Abstract and Applied Analysis, 2014 This paper is concerned with the problem of multilevel association rule mining for bridge resource management (BRM) which is announced by IMO in 2010. The goal of this paper is to mine the association rules among the items of BRM and the vessel accidents.
