MRI has relatively low sensitivity and specificity in detecting lymph node metastases. This study aimed to develop validate an radiomics-based model for predicting lateral pelvic (LPLN) metastasis rectal cancer patients who underwent LPLN dissection, compare its performance with that of radiologists. multicenter retrospective included 336 (199 men; mean age, 58.9 years ± 11.1 [standard deviation]) dissection. Patients were divided into development (n = 190) validation 146) cohorts. Radiomics...
One of the main challenges in excavating roadways is implementing temporary supports that are powered by hydraulics and have high strength. The current support system lacks active often causes separation between top plate layer below. It crucial to control initial roadway roof for stability surrounding rock, especially on with loose soft rock. This research focuses A4027 return airway Sail Six Mine. issues this been identified. concept principle using hydraulically driven, high-strength...
A hydroxyapatite/titania composite material was coated onto a titanium (pure Ti) substrate by the sol–gel method. HA (hydroxyapatite) and TiO2 (titania) sols were made from precursors separately mixed together. The sol Ti spin coating samples dried heat-treated at certain temperature. XRD data show that there is an improvement in crystallization growth of grain size as temperature increases. addition delayed accelerated its decomposition. has porous structure. also improved corrosion...
Bonded joints are very common in many pipeline systems, which the bond behavior of joint interface is crucial importance. This paper presents two analytical solutions for debonding process a pipe under torsion, assuming that follows either an exponential softening bond-slip law or simplified bilinear model. The general, applicable to composites and metallic indeed other pipes. Based on solutions, influences length stiffness torque-displacement curve ultimate load investigated. can be used...
To summarize the value of multislice spiral CT (MSCT) in differential diagnosis thick - wall gallbladder carcinoma (TWGC) and chronic cholecystitis (CC), clinical data 36 patients with TWGC 60 who were treated our hospital from January 2017 to May 2021 retrospectively analyzed, image features diagnostic accuracy summarized. Compared CC group, proportions disruption mucosa line, blurred outline, high obstruction biliary tract, lymphomegaly, adjacent invasion, peritoneal effusion, nodules,...
In order to better understand, describe and design the interfacial properties of pipe joints for pipeline structures in actual projects, this paper theoretically investigated mechanical adhesively bonded joint interface under simultaneous actions axial tensile loading temperature changes based on bilinear rigid-softening constitutive model.
