Real-time simultaneous localization and dense mapping is very helpful for providing virtual reality augmented surgeons or even surgical robots. In this letter, we propose MIS-SLAM: A complete real-time large-scale deformable SLAM system with stereoscope in minimal invasive surgery (MIS) based on heterogeneous computing by making full use of CPU GPU. Idled used to perform ORB-SLAM robust global pose. Strategies are taken integrate modules from We solved the key problem raised previous work,...
Hypoxia is a common feature of solid tumors and an important contributor to anti-tumor drug resistance. inducible factor-1 (HIF-1) one the key mediators hypoxia signaling pathway, was recently proven be required for sorafenib resistance in hepatocarcinoma (HCC). MicroRNAs have emerged as posttranslational regulators HCC. It reported that miR-338-3p levels are associated with clinical aggressiveness However, roles HCC disease its therapeutic drugs unknown. In this study, we found frequently...
Recently RGB-D sensors have become very popular in the area of Simultaneous Localisation and Mapping (SLAM). The major advantage these is that they provide a rich source 3D information at relatively low cost. Unfortunately, their current forms only range accuracy up to 4 metres. Many techniques which perform SLAM using cameras rely heavily on depth are restrained office type geometrically structured environments. In this paper, switching based algorithm proposed heuristically choose between...
Human-AI interactivity is a critical aspect that reflects the usability of Multimodal Large Language Models (MLLMs). However, existing end-to-end MLLMs only allow users to interact with them through language instructions, leading limitation interactive accuracy and efficiency. In this study, we present precise referring instructions utilize diverse reference representations such as points boxes prompts refer special region. This enables focus on region interest achieve finer-grained...
This paper presents a strategy for large-scale SLAM through solving sequence of linear least squares problems. The algorithm is based on submap joining where submaps are built using any existing technique. It demonstrated that if coordinate frames judiciously selected, the objective function two becomes quadratic state vector. Therefore, solution to requires number local either sequentially or in more efficient Divide and Conquer manner, can be obtained. proposed Linear technique applicable...
The main contribution of this paper is a novel feature parametrization based on parallax angles for bundle adjustment (BA) in structure and motion estimation from monocular images. It demonstrated that under certain conditions, describing locations using their Euclidean XYZ coordinates or inverse depth BA leads to ill-conditioned normal equations as well objective functions have very small gradients with respect some the parameters locations. proposed angle (ParallaxBA) avoids both above...
The long non‐coding RNA segment cancer susceptibility candidate 2 (CASC2) has been shown to suppress tumor growth in a variety of cancers, including hepatocellular carcinoma (HCC). However, the mechanism by which CASC2 exerts control over HCC yet be established. In present study, we first demonstrated that is downregulated human tissues and cell lines as compared adjacent non‐tumor (NTTs) liver line, respectively. After finding knockdown significantly promotes cells migration invasion well...
Purpose Automated technologies have been applied to facility management (FM) practices address labour demands of, and time consumed by, inputting processing manual data. Less attention has focussed on automation of visual information, such as images, when improving timely maintenance decisions. This study aims develop image classification algorithms improve information flow in the inspection-repair process through building modelling (BIM). Design/methodology/approach To automate process,...
This article presents a framework for 3D reconstruction of colonic surface using stereo colonoscopic images. Due to the limited overlaps between consecutive frames and nonexistence large loop closures during normal screening colonoscopy, state-of-art simultaneous localization mapping (SLAM) algorithms cannot be directly applied this scenario, thus colon model segmented from CT scans is used together with colonosocopic images achieve high accuracy. The proposed includes scan (point cloud RGB...
Two-dimensional (2-D)/3-D pose-graph simultaneous localization and mapping (SLAM) is a problem of estimating set poses based on noisy measurements relative rotations translations. This article focuses the relation between graphical structure SLAM Fisher information matrix (FIM), Cramér-Rao lower bounds (CRLB), its optimal design metrics (T-optimality D-optimality). As main contribution, assumption isotropic Langevin noise for rotation block-isotropic Gaussian translation, FIM CRLB are...
The sedimentary successions around the Carboniferous–Permian boundary (CPB) in Ordos Basin were investigated using extensive outcrop, borehole, well logging, thin section, and geochemistry data to study sequence stratigraphic responses glaciation volcanism paleotropical transitional strata. Within studied interval, five distinct lithofacies have been identified, including bauxite, coal, carbonaceous shale (No. 8 + 9 coal seams), sandstone (Qiaotou), limestone (Baode), mudstone, which can be...

Additionally, cell line HepG2 was purchased...
Joint optimization of poses and features has been extensively studied demonstrated to yield more accurate results in feature-based SLAM problems. However, research on jointly optimizing non-feature-based maps remains limited. Occupancy are widely used environment representations because they effectively classify spaces into obstacles, free areas, unknown regions, providing robots with spatial information for various tasks. In this paper, we propose Occupancy-SLAM, a novel optimization-based...

People living with HIV (PLWH) exhibit accelerated aging, characterized by systemic inflammation, termed "inflammaging." While T-cell expansion is prevalent in PLWH, its connection to inflammaging remains unclear. In this study, we analyzed the TCRβ repertoire of 257 healthy controls (HC) and 228 revealing pronounced T cell clonal PLWH.
