In this paper, a multi-vehicle multi-task non-orthogonal multiple access (NOMA) assisted mobile edge computing (MEC) system with passive eavesdropping vehicles is investigated. To heighten the performances of vehicles, we propose vehicle grouping pairing method, which utilizes near MEC to assist as full-duplex relays. For promoting transmission security, employ artificial noise interrupt vehicles. Furthermore, derive approximate expression secrecy outage probability system. The combined...

Abstract Gastric cancer (GC) stands as one of the most formidable malignancies worldwide. It is well-established that miRNAs play a crucial role in initiation and progression various human cancers. Among these, miR-99a-3p has been implicated pathogenesis GC. In context our study, we embarked on comprehensive examination expression GC cells. Additionally, sought to establish correlation between levels overall survival (OS) patients, findings hinted at its potential predicting an unfavorable...

Background: It has been well-recognized that the polysaccharides from Atractylodes macrocephala (PAM) are immune system enhancers, which can facilitate proliferation of lymphocytes and stimulate cells. Nevertheless, antitumor effects PAM their molecular mechanisms remain unclear. Aim: Our research aimed to evaluate anti-cancer on colorectal cancer (CRC). Methods: We tested growth CRC cells macrophages by MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The...

Neuropathy target esterase (NTE) is an endoplasmic reticulum (ER)-localized phospholipase that deacylates phosphatidylcholine (PC) and lysophosphatidylcholine (LPC). Loss-of-function mutations in the human NTE gene have been associated with a spectrum of neurodegenerative disorders such as hereditary spastic paraplegia, ataxia chorioretinal dystrophy. Despite this, little known about structure–function relationships between protein domains, enzymatic activity interaction cellular organelles....

Background The performance of artificial intelligence (AI) in the prediction lymph node (LN) metastasis patients with oral squamous cell carcinoma (OSCC) has not been quantitatively evaluated. purpose this study was to conduct a systematic review and meta-analysis published data on diagnostic CT MRI based AI algorithms for predicting LN metastases OSCC. Methods We searched Embase, PubMed (Medline), Web Science, Cochrane databases studies use Binary accuracy were extracted obtain outcomes...

Wireless Mesh Network (WMN) is a new kind of broadband Network, mainly used for different application scenarios wireless access. Hybrid Protocol (HWMP) default routing protocol provided WMN by IEEE 802.11s. However, problems exist in this protocol, such as large overhead, low efficiency and so on. This paper propose mechanism, Source Node Compute Routing (SNCR) solving above problems, the source node to quickly calculate best-metric route any destination intra-mesh. The proposed also...

Applications of the digital image correlation method (DIC) for determination opening mode stress intensity factor (SIF) is investigated using an edge cracked aluminum plate in this paper. Standard compact tension test specimen was tested under tensile loading and full-field displacement fields sample were recorded DIC. The SIF associated with unavoidable rigid-body translation calculated simultaneously from experimental data by fitting theoretical field least-squares. Selection convergence...

The low and medium speed bird-strike impact damage of sandwich composite structure drone radome during takeoff landing is examined by numerical simulations, using nonlinear dynamic finite element analysis software LS-DYNA. For different velocities, the aircraft radome’s responses are obtained in panel clearly demonstrated. relations energy, maximum force state analyzed. simulation results can provide some references for design.

Objective:To explore the value of computed tomography angiography （CTA） combined with digital technology in vascular anatomy anterior thigh flap patients operative defects after head, neck and maxillofacial tumor operation, design preoperative intraoperative flaps. Methods:Twenty-five cases postoperative defect surgery admitted to our hospital from April 2018 2019 were selected. Preoperative CTA used clarify other related conditions, operation was carried out. Consistency analysis applied...

In this paper, we investigate a multi-vehicle multi-task non-orthogonal multiple access (NOMA) based mobile edge computing (MEC) system with passive eavesdropping vehicles. To enhance the performance of vehicles, propose vehicle grouping and pairing method (GPM) to employ near MEC acting as full-duplex (FD) relay assist order improve transmission security, artificial noise (AN) is used interfere The approximate expression secrecy outage probability (SOPS) derived in closed form. This paper...

An old woman presented with a hematoma in the right frontal gyrus rectus, hematocele ventricles and subarachnoid space on Computed tomography imagings(CT). Three-dimensional bone subtraction computed (3DBSCTA) was performed 16 slices multidetector-row CT scanner applying volume rendering technique saccular aneurysm located A2 segment of cerebral anterior artery revealed. The clipped pterional craniotomy. Another fusiform orbital found accidently surgery. not shown three-dimensional (3DCTA)...

The ectopic thyroid gland is a rare disease in which abnormal migration of the embryonic germ thought to be basis for formation gland. A 37 year old female sought medical attention due feeling sensation swallowing foreign objects, without any other positive symptoms such as pain or difficulty breathing. Preoperative examination revealed nodule left lobe and behind lobe. patient ultimately underwent non-inflatable endoscopic surgery under axilla completely remove tumor located suprasternal...

头颈部鳞癌包括口腔颌面部肿瘤、喉癌、甲状腺癌、鼻咽癌等，是世界上常见恶性肿瘤之一。迄今确切的病因尚不清楚，可能是吸烟、饮酒、病毒感染等多种因素综合所致。尽管目前诊断手段、手术治疗及化疗水平比过去几十年都有提高，但头颈肿瘤5年的生存率仍然在50%左右。有文献报道，MicroRNA（miRNA）在多种人类肿瘤细胞中异常表达，并且参与调节肿瘤细胞的增殖、分化及凋亡等多个生物学过程，其突变、缺失或表达水平的异常与人类肿瘤的发生、发展密切相关。

Abstract Background: Yolk sac tumor also known as endodermal sinus tumor, is a rare intracranial germ cell tumor. We reported case of yolk in cerebellar hemisphere, and reviewed associated literatures. The majority locations are near the midline. On review literature, very few reports have been published, there only one report has described arising from cerebellum. Case presentation: A two years old boy admitted to our hospital due headache unsteady gait for six days. CT MRI demonstrated...
