Abstract Introduction: Half of men aged > 60 years will develop benign prostatic hyperplasia (BPH) with 40% of these men having moderate-to-severe lower urinary tract symptoms (LUTS). There is limited knowledge on a head-to-head comparison of prostatic urethral lift (UroLift) and convective water vapor ablation (Rezum) for the treatment of LUTS secondary to BPH. We sought to compare randomized controlled trials with 3-year clinical outcome data.
Materials and methods: After a thorough literature search, two multicenter sham-controlled double-blind randomized trials for UroLift and Rezum were identified and compared. Both studies had similar designs, baseline characteristics, reported outcomes, and… More >

Abstract Research on the population in western world showed that, MSE (muscle-strengthening exercise) is beneficial to the treatment of mental disorders. However, the situation in Chinese adults is little known. For this reason, the study is performed to understand the connection between depression and MSE among college and university students in China aged between 18 to 24.1793 college students have been recruited, and their average age is 20.67. A questionnaire has been developed and it is self-reported and designed to collect information about MSE and participants, including body mass index and sex and so on. Sleep… More >

Abstract Reducing drag during take-off and nominal (cruise) conditions is a problem of fundamental importance in aeronautical engineering. Existing studies have demonstrated that v-shaped symmetrical riblets can effectively be used for turbulence control, with those with dimensionless depth h⁺ = 15 and dimensionless width s⁺ = 15 having the best drag reduction effect. In the present study, experimental tests have been conducted considering two models of the same size, one with smooth surface, the other with v-shaped riblets of the h⁺ = 15 and s⁺ = 15 type. The results show that for an angle of attack in More >

Abstract In this study, we investigated warpage and corner lifting minimization for three-dimensional printed parts generated by macro-size fused deposition modeling (FDM). First, the reasons for warpage were theoretically elucidated. This approach revealed that the thermal deformation and differential volumetric shrinkage of the extruded molten plastic resulted in warpage of FDM parts. In addition, low adhesion between the deposited model and the heated or non-heated printing bed may intensify warpage further. As a next step, initial small-size and medium-size models were used to identify parameters to manage and minimize warpage in a way that would reduce… More >

Abstract Steganography has been used to prevent unauthorized access to private information during transmission. It is the scheme of securing sensitive information by concealing it within carriers such as digital images, videos, audio, or text. Current steganography methods are working by assigning a cover file then embed the payload within it by making some modifications, creating the stego-file. However, the left traces that are caused by these modifications will make steganalysis algorithms easily detect the hidden payload. Aiming to solve this issue, a novel, highly robust steganography method based on hacking anti-shoplifting systems has proposed to… More >

Abstract Introduction: To report the early postoperative patient experience, including symptom response, catheterization, recovery and satisfaction, following treatment with two minimally invasive surgical therapies (MIST) for benign prostatic hyperplasia (BPH): mechanical disobstruction with UroLift prostatic urethral lift (PUL) and tissue ablation with steam injection (Rezum).
Materials and methods: Patient reported outcomes of 53 non-retention patients from two U.S. sites who underwent PUL (n = 30) or Rezum (n = 23) were collected within 2 months post-treatment. There were no exclusion criteria for baseline symptoms, prostate size, or BPH medical therapy. Patients completed questionnaires which assessed postoperative BPH symptoms… More >

Abstract With the increasing number of horizontal wells with low pressure, low yield, and water production, the phenomenon of water and liquid accumulation in gas wells is becoming progressively more serious. In order to fix these issues, it is necessary to improve existing drainage and gas recovery technologies, increase the fluid carrying capacity of these wells, and ensure that the bottom-hole airflow has enough energy to transport the liquid to the wellhead. Among the many techniques of drainage and gas recovery, the gas lift has recently become a popular method. In the present study, through the… More >

Abstract The buoyancy of groundwater can reduce the foundation bearing capacity and cause the metro tunnels to float as a whole, which threatens the safety of structures seriously. Therefore, uplift piles are set up to improve the structural stability. In this paper, FLAC3D software is used to establish the calculation models of pile foundation. The bearing failure process of uplift piles was simulated to study the influencing factors on single pile load bearing capacity as well as the cooperative work laws of pile groups. The load-displacement curves of pile top under different length-diameter ratios, pile-soil interface… More >
