Time-series domain adaptation via sparse associative structure alignment: Learning invariance and variance.

Domain adaptation on time-series data, which is often encountered in the field of industry, like anomaly detection and sensor data forecasting, but received limited attention in academia, is an important but challenging task in real-world scenarios. Most of the existing methods for time-series data use the covariate shift assumption for non-time-series data to extract the domain-invariant representation, but this assumption is hard to meet in practice due to the complex dependence among variables and a small change of the time lags may lead to a huge change of future values. To address this challenge, we leverage the stableness of causal structures among different domains.

Objective: To evaluate the effectiveness of medial buttress plate augmented hollow lag screws fixation in combination with sartorius pedicled iliac flap for the treatment of femoral neck fractures in young adults.

Methods: The clinical data of 11 young adult patients with femoral neck fractures between February 2013 and February 2019 were analyzed retrospectively. There were 7 males and 4 females with a mean age of 45 years (range, 32-58 years).

Clinical outcomes of doubled-suture Nice knot augmented plate fixation in the treatment of comminuted midshaft clavicle fracture.

Background: Free bone fragments were difficult to be fixed in many comminuted midshaft clavicle fractures, and the absence of cortical alignment in comminuted fractures had direct influence on the stability of fixation. This survey was performed to assess the efficacy of doubled-suture Nice knot augmented plate fixation in the treatment of comminuted midshaft clavicle fractures.

Methods: Between 2013 and 2018, all patients with comminuted midshaft clavicle fractures treated with doubled-suture Nice knot augmented plate fixation were retrospectively reviewed and included in this research.

Measurement of the sound velocity of shock compressed water.

The sound velocities of water in the Hugoniot states are investigated by laser shock compression of precompressed water in a diamond anvil cell. The obtained sound velocities in the off-Hugoniot region of liquid water at precompressed conditions are used to test the predictions of quantum molecular dynamics (QMD) simulations and the SESAME equation-of-state (EOS) library. It is found that the prediction of QMD simulations agrees with the experimental data while the prediction of SESAME EOS library underestimates the sound velocities probably due to its improper accounting for the ionization processes.

Adjacent two-level anterior cervical discectomy and fusion versus one-level corpectomy and fusion in cervical spondylotic myelopathy: Analysis of perioperative parameters and sagittal balance.

Objectives: The optimal surgical strategy for cervical spondylotic myelopathy (CSM) remains controversial; thus, the current study was designed to compare the outcomes of two different anterior approach surgeries for two-level CSM, namely, adjacent two-level anterior cervical discectomy and fusion (ACDF) and one-level anterior cervical corpectomy and fusion (ACCF).

Patients And Methods: A total of 53 patients who underwent adjacent two-level ACDF and 68 patients who underwent one-level ACCF in the Spinal Surgery Department from January 2010 to October 2017 were retrospectively analyzed. Independent sample t tests and chi-square tests were used to compare perioperative parameters (hospital stays, bleeding amounts and operation times), clinical parameters (Neck Disability Index scores and Visual Analog Scale scores for neck and arm pain), and radiologic parameters (difference in segmental height, T1 slope, C2-7 sagittal vertical axis, C2-7 lordosis, segmental angle, and fusion rate).

[Effect of screw blade position on proximal femoral nail anti-rotation internal fixation for unstable intertrochanteric fractures in the elderly].

Objective: To investigate the effect of the screw blade position on the effectiveness of proximal femoral nail anti-rotation (PFNA) internal fixation for unstable intertrochanteric fractures in the elderly.

Methods: A clinical data of 131 elderly patients with unstable intertrochanteric fractures who were treated with PFNA internal fixation between January 2010 and January 2017 was retrospectively analyzed. According to the anteroposterior X-ray films, the screw blades were placed in the middle of the femoral neck in 72 patients (group A) and at one-third of the femoral neck in 59 patients (group B).

Adsorption of Cu(II) by phosphogypsum modified with sodium dodecyl benzene sulfonate.

Phosphogypsum (PG) is a solid waste generated during the wet production of phosphoric acid, and stockpiling PG causes serious pollution to the environment. Therefore, we prepared an adsorption material modified with sodium dodecyl benzene sulfonate (SDBS) based on PG (SDBS@PG). SDBS@PG can be regenerated and used in several adsorption-desorption cycles.

The modified anterior ellipsoidal cap titanium cable tension band for comminuted patellar fractures.

Purpose: The purpose of this study was to assess the outcomes in a series of patients, who underwent cerclage and figure-of-eight tension band wiring using a single titanium cable for comminuted patellar fractures.

Methods: We describe a modified tension band technique using a single titanium cable to create an ellipsoidal cap structure that combines the circumferential and figure-of-eight wrapping in the fixation of closed Association for the Study of Internal Fixation/Orthopaedic Trauma Association 34C2 and 34C3 patellar fractures. We retrospectively reviewed 25 patients (16 males and 9 females, mean age 54 years) who underwent the described fixation technique between 2015 and 2017.

Metformin alleviates hyperglycemia-induced apoptosis and differentiation suppression in osteoblasts through inhibiting the TLR4 signaling pathway.

Aims: Metformin was found to protect against hyperglycemia-induced injury in osteoblasts, but the cellular mechanisms involved remain unclear.
