Abstract

The large amount of data collected by LiDAR sensors brings the issue of LiDAR point cloud compression (PCC). Previous works on LiDAR PCC have used range image representations and followed the predictive coding paradigm to create a basic prototype of a coding framework. However, their prediction methods give an inaccurate result due to the negligence of invalid pixels in range images and the omission of future frames in the time step. Moreover, their handcrafted design of residual coding methods could not fully exploit spatial redundancy. To remedy this, we propose a coding framework BIRD-PCC. Our prediction module is aware of the coordinates of invalid pixels in range images and takes a bidirectional scheme. Also, we introduce a deep-learned residual coding module that can further exploit spatial redundancy within a residual frame. Experiments conducted on SemanticKITTI and KITTI-360 datasets show that BIRD-PCC outperforms other methods in most bitrate conditions and generalizes well to unseen environments.

G6PD IManKang (517 T→C; 173 Phe→Leu): A New Chinese G6PD Variant Associated with Neonatal Jaundice

“…Of these, the 1376 mutation is the most common allele, accounting for nearly 55% of deficiency cases in the Chinese population of Taiwan [2,3,6]. In contrast, the 493 and 592 mutations are two major mutant alleles for the Saisiat and the Ami, respectively [4], In this communication, we report a novel G6PD mutation (517 T->C; 173 Phe->Leu) found in a Chinese infant with neonatal jaun- with modification [17], Briefly, the whole-blood sam ple or pre-extractcd patient's DNA was subjected to PCR amplification using G6PD-specific primer sets that covered the entire coding region of the G6PD gene [15,17], The PCR amplification procedure was per formed as previously described [ 15 . 17], The amplified PCR-SSCP products were analysed in a mini-gel sys tem and by ethidium bromide staining.…”

“…The F8C/G6PD haplotype, constructed from four polymorphic sites -(1) a ///« d ill site in the F8C gene, (2) the 1311 C ->T mutation in the G6PD gene, (3) a M alll site in the G6PD gene, and (4) an /fcoRI site located 20 kb downstream of the G6PD gene -was examined as previously described [ 18] with some mod ification [17].…”

Intermetallic compounds formed during diffusion soldering of Au/Cu/Al2O3 and Cu/Ti/Si with Sn/In interlayer

“…The intermetallic compounds formed at the diffusion-soldered interfaces between Cu/Ti/Si and Au/Cu/Al 2 O 3 with pure Sn and pure In interlayers have been investigated by Liang et al 5 and Tsao et al, 6 respectively. In the wake of published studies on intermetallic reactions of liquid In-49Sn solder with solid Au and Cu substrates, 7,8 this present paper is concerned with thin-film diffusion soldering between Cu/Ti/Si and Au/Cu/Al 2 O 3 using a near-eutectic In/Sn interlayer.…”

Interfacial Reaction and Wetting Behavior Between Pt and Molten Solder

“…At all other temperatures and times used in this study, only Ni 3 Sn 4 formed, which is consistent with the literature results. [8][9][10][11][12] These Ni 3 Sn 4 grains had an aspect ratio close to 1, as shown in Fig. 1d.…”
