We introduce a particle-hole-symmetric metallic state of bosons in a magnetic field at odd-integer filling. This state hosts composite fermions whose energy dispersion features a quadratic band touching and corresponding 2π Berry flux protected by particle-hole and discrete rotation symmetries. We also construct an alternative particle-hole symmetric state-distinct in the presence of inversion ...

BACKGROUND 3D ultrasound volume reconstruction from B-model ultrasound slices can provide more clearly and intuitive structure of tissue and lesion for the clinician. METHODS This paper proposes a novel Global Path Matching method for the 3D reconstruction of freehand ultrasound images. The proposed method composes of two main steps: bin-filling scheme and hole-filling strategy. For the bin-f...

This paper presents systematic investigations on complete through hole filling for cores using a Cu electroplating process as an alternative to the common paste plugging process [1]. This technology is targeting at both HDI production and also at the packaging level [2]. This electro plating process consists of two steps, a first process to merge both centers of the through hole walls (X-platin...

A new technique for filling narrow and high-aspect ratio nanoscale via holes by laser-assisted direct imprint has been proposed and developed. In the process, the filling material (e.g., metals or Si) is first deposited onto the nano-via holes by a deposition method that has a poor step coverage and hence fills the holes partially with voids. Then a mirror-flat transparent plate (mold) is press...

 In conventional photonic crystal fibers (PCF’s),the cladding structure is usually formed by air holes with the same diameter arrayed in regular triangular lattice. However, in index guiding PCF’s means in Hole Assisted Fiber, the periodicity in the cladding region is not essential to confine the guiding light in to the high-index core region. Hole Assisted Fiber (HAF) technology is investigat...

We study an Anderson impurity in a semiconducting host using the density matrix renormalization group technique. We use the U = 0 one–dimensional Anderson Hamiltonian at half filling as the semiconducting host since it has a hybridization gap. By varying the hybridization of the host, we can control the size of the semiconducting gap. We consider chains with 25 sites and we place the Anderson i...

Depth-image-based rendering (DIBR) oriented view synthesis has been widely employed in the current depth-based 3D video systems by synthesizing a virtual view from an arbitrary viewpoint. However, holes may appear in the synthesized view due to disocclusion, thus significantly degrading the quality. Consequently, efforts have been made on developing effective and efficient hole filling algorith...
