Frame-Assisted Reduction of a B-Type Pilon Fracture Dislocation: Talar Body Incarceration on an Intact Fibula
Authors: Campbell Sean T. , DeBaun Malcolm R. , Githens Michael F. 
Published: February 2021

Case:
We describe an irreducible anterolateral tibiotalar dislocation with an AO/OTA (Arbeitsgemeinschaft fur Osteosynthesefragen/Orthopaedic Trauma Association) B-type pilon fracture. The injury was initially treated with closed reduction, using a medializing force achieved with an external fixator to unhinge the talar body from the fibula, followed by temporary stabilization. Definitive fixation was performed once the soft tissues had recovered.

Conclusion:
This unique irreducible pilon fracture dislocation pattern is important to recognize to prevent iatrogenic complications associated with multiple failed closed reduction attempts. Frame-assisted, percutaneous, or open maneuvers may be required to facilitate a reduction. Staged treatment with temporization in an external fixator may be required.

Published: February 2021

Abstract
Without hindering the taste, making a cigarette less harmful by reducing the percentage of toxic and carcinogenic compounds in the smoke of the cigarette is the challenging task for the current generation researchers. In the current work, by implementing mechanical and chemical modification techniques, the above stated is tried to mitigate. In addition to the above, the optimized suction pressure, burning time and the number of puffing are determined. Then, at the optimized conditions, the modifications are implemented. Mechanical modification technique considers filter to cigarette ratio and filter design. The mathematical calculation reveals that puffing stops when the cigarette length reaches 0.15 times of its original length. Furthermore, it also identified that the concentration of suspended solids and droplets in the smoke decreases significantly (separation efficiency = 56.81%) if the cigarette to filter ratio is 2.32. In the case of chemical modification, various adsorbents such as charcoal and Zeolite 13X used to reduce the harmful effect in the output. These processes depict reduction in harmful effect (separation efficiency up to 62.1%) by showing decrement in the suspended solids and droplets in the smoke due to the adsorption on the active sites of charcoal and Zeolite 13X. In the case of combined modifications, the achieved separation efficiency is 66.51%. For the experimentation, an experimental setup fitted with artificial lungs. Characterization methods such as XRD, SEM, and EDX of cigarette filter, burnt charcoal part, ash, raw tobacco and mathematical calculation approve the improvement due to the modification of cigarette.

Abstract
In this paper, we have investigated the transport of topological edge states in 2D Zigzag edge Tungsten Ditelluride Nanoribbon (ZTDNR).We have found that zigzag edge nanoribbon (NR) of Tungsten Ditelluride develops topological edge states in the presence of intrinsic spin orbit interaction (SOC). We have used three band tight binding model for the electrons of dz2 , dxy, and dx2 - y2 orbitals with SOC for calculating band structure of NR and Non Equilibrium Greens Function (NEGF) formalism for transport in the NR. We have investigated transport in a pristine device, transport in the presence of a finite potential barrier, transport with constriction within the device and transport with edge imperfections.

Abstract
To further explore the development of construction waste recycling enterprises and promote the recycling of construction waste resources in China, a system dynamics model of the economic benefits of construction waste recycling enterprises is established using the system dynamics method and taking the tax incentive of the Guangzhou Municipal Government as an example. The economic benefits of construction waste recycling enterprises are analyzed from the perspective of the total cost, total revenue, and total recycling amount. The results of the MATLAB simulation and numerical analysis show that: (1) By simulating the effects of different taxes such as value-added tax (VAT), education surcharge, urban construction tax, and enterprise income tax on the economic benefits of construction waste recycling enterprises, it is found that when tax incentives reach 70%, the VAT favorable policies bring the highest gains, followed by enterprise income tax, whereas favorable education surcharge policies and urban construction tax have the least impact on economic benefits. (2) Taking the monetary subsidy of the Guangzhou municipal government as an example, it is estimated that the total revenue of construction waste recycling enterprises will increase by 33.56% annually in 2030. When the new production technology is adopted, the Return On Investment (ROI) will reach 46.8% in 2030 compared to previous technological improvement. In the simulation scenario, the ROI will be 42.2%, which has a good incentive effect on the cost control of enterprises. (3) Increasing the available power to VAT and corporate income tax can improve the profitability of construction waste recycling enterprises in China; however, tax incentive policy will no longer be the main factor affecting the benefits of enterprises when a certain time is reached. (4) It is suggested that the government improves the relevant tax laws incentive policies, increase tax incentives, and add equipment tax incentive policies, actively change the tax mode, and increase indirect tax models to improve the economic benefits of enterprises. The research results provide a decision-making reference for the government to formulate laws and policies related to the economic benefits of construction waste recycling, promote the development of the construction waste recycling industry, the development of new industries, such as waste recycling and treatment, and the formation of industrial chains, to achieve the strategic goal of sustainable development.

Abstract
This study fabricated polylactic acid (PLA)/kenaf cellulose fiber biocomposite filaments via melt-extrusion process. Kenaf cellulose fibers (KF) were chemically extracted from locally grown kenaf plants and used as reinforcement. Moreover, the KF was then treated with tetraethyl orthosilicate (TEOS), so-called KFs, to improve the compatibility between the fibers and PLA matrix. Also, the plasticizers (polyethylene glycol) were incorporated to enhance the flowability and processability of the biocomposites. The melt viscosities of the biocomposites increased as the solid KF and KFs were loaded. However, they were significantly decreased with the addition of plasticizers. The combined use of the plasticizers and TEOS treatment improved tensile strength, Young’s modulus and elongation of the biocomposites compared to the neat PLA. The obtained PLA/KFs biocomposite materials are proved to be a mechanical-improved material, which offers the opportunity for customized and rapid prototyping of biocomposite products.
Compensation method for complex hysteresis characteristics on piezoelectric actuator based on Separated Level-loop Prandtl–Ishlinskii model

Published: February 2021

Abstract
Piezoelectric ceramic actuators exhibit nonlinear hysteresis characteristics owing to their material properties. To modify the inverse piezoelectric effect as an ideal linear execution, the classical Prandtl–Ishlinskii (PI) model is usually used for compensation by feedforward control. The PI model compensates well on simple hysteresis characteristics. However, when the output requirements are complex, the PI model demonstrates uneven compensation accuracy on the complex hysteresis characteristics and cannot achieve an accuracy similar to that of simple hysteresis. This paper proposes a simplification of complex hysteresis: Separated Level-loop PI (SLPI) model. First, we use a loop-separation logic algorithm to simplify the complex hysteresis characteristics to obtain hysteresis in the form of single loops with loop levels and vertexes. Second, the hysteresis characteristics of each loop are independently modeled using the PI model. Finally, the inverse model is reconstructed using a rollback method to restore a positive sequence of the feedforward voltage; then, the feedforward voltage is input as a compensation value to achieve higher and more uniform accuracy. Experiments and discussions show that the SLPI model can effectively improve the compensation results of complex hysteresis characteristics; moreover, the average compensation accuracy difference between single hysteresis loops was reduced.

Abstract
Background: Lung cancer is the most common neoplasm among all cancers worldwide. Early diagnosis with minimal invasive procedures is ideal for lowering the patients’ burden and increasing survival rates. The value of serum tumor biomarkers used in lung cancer screening is still controversial in clinical practice.Methods: Serum levels of ProGRP, NSE, SCC-Ag, CEA, CYFRA21-1, and HE4 were measured using the chemiluminescence immunoassay in apparently healthy Chinese individuals, as well as in those with benign non-cancerous diseases, lung cancer patients, and those suffering other types of malignancies. Data was analyzed utilizing the SPSS version 18.0 statistical software. Results: All 6 serum biomarkers in lung cancers were significantly higher than in benign non-cancerous diseases and healthy controls. HE4 levels in benign diseases were significantly higher than in healthy controls. SCC-Ag, CEA, and CYFRA21-1 levels in lung cancers were significantly higher than in other malignancies. ProGRP and NSE levels in SCLC were significantly higher than in other histologic types; SCC-Ag and CYFRA21-1 levels in SCC were significantly higher than in other histologic types; the HE4 level in SCLC was also significantly higher than in SCC and adenocarcinoma, while adenocarcinoma had the highest serum CEA level comparing to SCC and SCLC. Serum ProGRP, NSE, and HE4 in SCLC were significantly higher than in NSCLC, SCC-Ag level in NSCLC was significantly higher than in SCLC. All biomarkers in advanced stages were significantly higher than in lower stages. NSE, HE4, and ProGRP presented relative high performance in SCLC. CYFRA21-1, HE4, and SCC-Ag indicated relative high performance in SCC. All biomarkers had relatively low performance on adenocarcinoma histologic type. The best performance of 2-marker combination was SCC-Ag+CYFRA21-1 for SCC, ProGRP+NSE for SCLC, CEA+CYFRA21-1 for adenocarcinoma. A combination of SCC+CEA+CYFRA21-1 gained highest performance for NSCLC.Conclusions: A 6-biomarker panel had capability on characterizing lung cancer and presented high performance individually and combinatorically on different histologic types of the neoplasm. HE4 showed high sensitivity to all histologic types of the malignancy; however, one should be cautious since its level also increased in benign non-cancerous diseases.
