Target detection and tracking algorithms are one of the key technologies in the field of autonomous driving in intelligent transportation, providing important sensing capabilities for vehicle localization and path planning. Siamese network-based trackers formulate the visual tracking mission as an image-matching process by regression and classification branches, which simplifies the network structure and improves the tracking accuracy. However, there remain many problems, as described below.

Materials And Methods: Nineteen healthy Chinese volunteers participated in this study, which utilized a block design with four language tasks: auditory naming (AN), picture naming (PN), verbal fluency-character (VFC), and verbal fluency-letter (VFL). All functional images were preprocessed by SPM 8, followed by first- and second-level analyses and lateralization index calculation.
Objective: To evaluate the epidemiological and morphological characteristics of coronary plaque in diabetic patients with symptomatic coronary heart disease (CHD) by dual-source computed tomography (DSCT).
Materials And Methods: From June 2013 to December 2014, 267 consecutive patients with type 2 diabetes mellitus were examined by DSCT. Plaque type, distribution, as well as extent and obstructive characteristics were determined for each segment.
Injuries sustained by earthquake relief workers: a retrospective analysis of 207 relief workers during Nepal earthquake.
Scand J Trauma Resusc Emerg Med
July 2016
Background: This study aimed to analyse the injuries sustained by rescue workers in earthquake relief efforts in high altitude areas for improving the ways of how to effectively prevent the injuries.
Methods: The clinical data of 207 relief workers from four military hospitals in Tibet, who were injured in the Tibetan disaster areas of China during '4.25' Nepal earthquake rescue period, was retrospectively analyzed.
Aims: The cardiovascular risk factors and diabetic complications are related to coronary atherosclerosis. However, the evaluation of the prevalence of coronary atherosclerosis based on their accumulation remains to be determined.
Methods: 247 consecutive Chinese subjects with type 2 diabetes but without history of coronary heart disease (CHD) underwent 320-slice computed tomographic coronary angiography, including no coronary atherosclerosis, non-obstructive atherosclerosis (<50% stenosis) and obstructive atherosclerosis (≥50% stenosis).
Primary Objective: To investigate the epidemiology of TBI in Chinese inpatients.
Research Design: Civilian inpatients of Chinese military hospitals diagnosed with TBI between 2001-2007 were identified using ICD-9-CM codes.
Methods And Procedures: Demographic characteristics, admission time, injury cause, injury severity, length of stay and outcomes were compared between ICD-9-CM diagnosis groups.
T2 mapping outperforms normalised FLAIR in identifying hippocampal sclerosis.
Neuroimage Clin
January 2016
Rationale: Qualitatively, FLAIR MR imaging is sensitive to the detection of hippocampal sclerosis (HS). Quantitative analysis of T2 maps provides a useful objective measure and increased sensitivity over visual inspection of T2-weighted scans. We aimed to determine whether quantification of normalised FLAIR is as sensitive as T2 mapping in detection of HS.

Materials And Methods: Sixty-four patients with HCC underwent CT perfusion scanning with a 320-detector row CT before and after TACE. With the help of built-in dual-source CT perfusion software, color perfusion images of hepatic arterial perfusion (HAP), portal vein perfusion (PVP) and hepatic arterial perfusion index (HAPI) of all HCC lesions were obtained, and the above perfusion parameters were measured on the color images.
Purpose: The role of spot sign on computed tomography angiography (CTA) for predicting hematoma expansion (HE) after primary intracerebral hemorrhage (ICH) has been the focus of many studies. Our study sought to evaluate the predictive accuracy of spot signs for HE in a meta-analytic approach.
Materials And Methods: The database of Pubmed, Embase, and the Cochrane Library were searched for eligible studies.
Purpose: Differentiation of high-grade gliomas and solitary brain metastases is an important clinical issue because the treatment strategies differ greatly. Our study aimed to investigate the potential value of diffusion tensor imaging (DTI) in differentiating high-grade gliomas from brain metastases using a meta-analytic approach.
Materials And Methods: We searched Pubmed, Embase and the Cochrane Library for relevant articles published in English.
Background: Lower extremity atherosclerosis (LEA) is among the most serious diabetic complications and leads to non-traumatic amputations. The recently developed dual-source CT (DSCT) and 320- multidetector computed tomography (MDCT) may help to detect plaques more precisely. The aim of our study was to evaluate the differences in LEA between diabetic and non-diabetic patients using MDCT angiography.

We evaluated the prevalence and morphology of carotid and cerebrovascular atherosclerotic plaques in T2DM patients with transient ischemic attack (TIA) or stroke using multidetector CT (MDCT).
Methods: 64-MDCT and dual-source CT (DSCT) angiographies were performed in 195 T2DM patients with TIA or stroke (mean age 65.
Purpose: To clarify the differences of the carotid and cerebrovascular disease between patients with and without type 2 diabetes using dual-source CT angiography.
Materials And Methods: Dual-source CT angiography of the carotid and cerebrovascular arteries was performed in 79 type 2 diabetic patients and 207 non-diabetic patients. The type, extent and distribution of plaques, and luminal stenosis were compared.
Background: Plaque morphology directly correlates with risk of embolism and the recently developed dual-source computed tomography angiography (DSCTA) may help to detect plaques more precisely. The aim of our study was to evaluate the prevalence and morphology of carotid and cerebrovascular atherosclerotic plaques in patients with symptomatic type 2 diabetes mellitus (DM) by DSCTA.
Methods: From July 2009 to August 2010, DSCTA was prospectively performed in 125 consecutive patients with symptomatic type 2 DM.
Article Synopsis
- Coronary artery disease (CAD) is a serious complication in patients with type 2 diabetes mellitus (DM), and this study aims to analyze its characteristics using coronary CT angiography (CTA).
- Among 113 diabetic patients, the study found that multi-vessel disease was more prevalent than single vessel disease, with the left anterior descending artery being the most affected area.
- The majority of plaques were calcified and mild narrowing of vessels was the most common, though there was no significant difference in the severity of stenosis between genders.
