Thermomechanical stress generation on a silicon chip in an embedded-die package (EDP) was investigated. Change thermomechanical the with temperature evaluated using piezo-resistance gauges fabricated chip. To investigate impact of redistribution layer (RDL) generation, EDP where filling materials facing top and bottom sides periphery embedded die were entirely removed fabricated. The removal ca...

The reciprocal distance Laplacian matrix of a connected graph G is defined as RDL(G)=RT(G)−RD(G), where RT(G) the diagonal degrees and RD(G) Harary matrix. Clearly, RDL(G) real symmetric matrix, we denote its eigenvalues λ1(RDL(G))≥λ2(RDL(G))≥…≥λn(RDL(G)). largest eigenvalue λ1(RDL(G)) RDL(G), denoted by λ(G), called spectral radius. In this paper, obtain several upper bounds for sum k in terms...

ecently, water regulatory agencies and providers have shown considerable interest in determining the lowest quantifiable level that is suitable for regulatory purposes.1–8 Allowable concentration levels for a contaminant in a particular environmental medium (e.g., soil, air, or water) are often based on health-related risk assessments and are sometimes lower than levels that can be quantitated ...

  ABSTRACT   Background: While the benefits of Computed Tomography (CT) are well known in accurate diagnosis, those benefits are not risk free. CT is a device with higher patient dose in comparison with other conventional radiological procedures. Is the reduction of exposures by requiring optimization of CT procedures [a principle concern in radiological protection]? In this study, the radiatio...

OBJECTIVE To analyse the benefit of cochlear implantation in young deaf children with Waardenburg syndrome (WS) compared to a reference group of young deaf children without additional disabilities. METHOD A retrospective study was conducted on children with WS who underwent cochlear implantation at the age of 2 years or younger. The post-operative results for speech perception (phonetically b...

Microgrids can significantly improve the utilization of distributed generation (DG) and the reliability of the power supply. However, in the grid-tied operational mode, the interaction between the microgrid and the distribution network cannot be ignored. The paper proposes an equivalent modeling method for the microgrid under grid-tied mode based on a characteristic model. It can simplify the m...

Spatially and temporally resolved observations of near-surface air temperatures (Ta, 1.5–2 m above ground) are essential for understanding hydrothermal circulation at the land–atmosphere interface. However, the uneven spatial distribution of meteorological stations may not effectively capture the true nature of the overall climate pattern. Several studies have attempted to retrieve spatially co...

OBJECTIVE To study the efficacy, safety, and compliance of short-term electro-acupuncture for children with autism spectrum disorder (ASD). DESIGN Randomized, double-blind, sham-controlled, clinical trial. SUBJECTS AND METHODS Children with ASD were randomly assigned to an electro-acupuncture (EA) group (n=30) or a sham electro-acupuncture (SEA) group (n=25) matched by age and severity of a...
