Aims Appropriate acetabular component placement has been proposed for prevention of postoperative dislocation in total hip arthroplasty (THA). Manual placements often cause outliers in spite of attempts to insert the component within the intended safe zone; therefore, some surgeons routinely evaluate intraoperative pelvic radiographs to exclude excessive acetabular component malposition. However, their evaluation is often ambiguous in case of the tilted or rotated pelvic position. The purpose of this study was to develop the computational analysis to digitalize the acetabular component orientation regardless of the pelvic tilt or rotation. Methods Intraoperative pelvic radiographs of 50 patients who underwent THA were collected retrospectively. The 3D pelvic bone model and the acetabular component were image-matched to the intraoperative pelvic radiograph. The radiological anteversion (RA) and radiological inclination (RI) of the acetabular component were calculated and those measurement errors from the postoperative CT data were compared relative to those of the 2D measurements. In addition, the intra- and interobserver differences of the image-matching analysis were evaluated. Results Mean measurement errors of the image-matching analyses were significantly small (2.5° (SD 1.4°) and 0.1° (SD 0.9°) in the RA and RI, respectively) relative to those of the 2D measurements. Intra- and interobserver differences were similarly small from the clinical perspective. Conclusion We have developed a computational analysis of acetabular component orientation using an image-matching technique with small measurement errors compared to visual evaluations regardless of the pelvic tilt or rotation.

Published: July 2020

We describe an improved synthetic wavelength method for high-precision
long-distance measurement with a repetition-rate-locked femtosecond
laser modulated by a fiber Mach–Zehnder electro-optic intensity
modulator. Harmonics of the repetition rate accompanied with
modulating sidebands will be generated via intermode beating, which
will be utilized for high-precision ranging. The nonambiguity range is
significantly extended with a relatively low modulation frequency, and
the ambiguous distance is unwrapped by synchronous phase-shift
measurements of a synthetic wavelength chain without any auxiliary
measurement operation. Our experiment shows a precision better than
20 µm at 46 m range, and a high-precision translation stage is applied
for preliminary test and proof-of-principle demonstration. The
demonstrated system is simple and can be easily integrated, and it
will find widespread applications in large-scale metrology such as
large-volume manufacturing and precision formation flying.

Published: July 2020

A semi-classical seven-wave model is developed to investigate the noise performances of a degenerate dual-pump phase-sensitive amplifier. This approach takes into account the transfer to the signal, through multiple four-wave mixing processes, of the vacuum fluctuations injected into high-order waves. This effect leads to a degradation of the noise figure of the amplifier with respect to the 0 dB value predicted by the usual three-wave model. However, it is proved that a careful choice of the fiber dispersion allows us to use high-order waves to enhance the signal gain without degrading the noise figure above 1 dB.

Authors: Anugwom Chimaobi , Leventhal Thomas 
Published: July 2020

ABSTRACT
Cancer treatment has taken giant strides in recent years with the advent of immunotherapy, including checkpoint inhibitors. The use of these medications in liver transplant recipients has been debated, and the added effect of previous hepatitis C infection on the immune system in this setting, is poorly understood. We present a case of cholestatic hepatitis after the treatment of recurrent hepatocellular carcinoma with nivolumab in the post-transplant period. Understanding the pathophysiology is relevant to improving the management of this type of liver injury and expanding our knowledge of programmed death-1 inhibitors in liver transplant recipients.

Published: July 2020

INTRODUCTION:
Endoscopic submucosal dissection (ESD) is a preferred treatment option for superficial esophageal squamous cell carcinoma (SESCC). However, only few studies compared long-term survival outcomes of ESD with surgery. This study compared the overall survival (OS), recurrence-free survival, and complication rates of ESD with those of surgery.

METHODS:
We reviewed patients who underwent ESD (n = 70) or surgery (n = 114) for SESCC at Seoul National University Hospital from 2011 to 2017. A propensity score-matched analysis was used to reduce selection bias. To increase the precision of our results interpretation, subgroups were analyzed according to the depth of tumor invasion.

RESULTS:
In the matching study, the ESD group (n = 34) showed comparable survival outcomes with the surgery group (n = 34). The 5-year OS rates were 89.4% vs 87.8% for the ESD and the surgery groups, respectively; similarly, the 5-year recurrence-free survival rates were 90.9% and 91.6%, respectively. The ESD group showed a lower early major complication rate (2.9% [1 of 34] vs 23.5% [8 of 34], P < 0.001) and shorter hospital stay (median, 3.0 days vs 16.5 days, P < 0.001) than the surgery group. In the tumor in situ (Tis)-subgroup, ESD showed better OS than esophagectomy (P = 0.030). Between-group comparisons of survival outcomes in the T1a and T1b subgroups revealed no significant differences.

DISCUSSION:
Long-term outcomes of ESD are comparable with surgery for patients with SESCC. For early major complications and duration of hospital stay, ESD was associated with better outcomes than radical surgery. These results support ESD as the preferred treatment option for SESCC.
Displacement and deformation study of engineering structures with the use of modern laser technologies
Authors: Sztubecki Jacek , Bujarkiewicz Adam , Derejczyk Karol , Przytuła Michał 
Published: July 2020

Abstract
Modern measuring technologies give the means to perform tasks previously impossible with conventional methods. Their main advantages include reduced time consumption and higher measurement precision. Contemporary displacement and deformation studies of engineering structures often involve application of laser technologies, which are characterised by high precision of measurements. This article presents an analysis of results obtained from measurements of changes in the geometry of an engineering structure in which two complementary measuring technologies were used, i.e. tachymetric measurement with a Leica TDRA6000 laser station and laser scanning with a 3D FARO Focus S150 scanner. The utilised laser station enabled determination of 3D displacements in the local control point network installed on the studied structure as well as transfer of point clouds obtained from laser scans into a uniform coordinate system. The hybrid technology employed and the measurement method used ensured that the accuracy of the determined displacements and deformations of the structural components of the structure was high. The described measurement and result processing technology makes it possible to comprehensively analyse the geometric performance of structures, which consequently leads to the development of more complete conclusions concerning prevention of adverse effects of displacements and deformations in engineering structures.
Virtual resolution enhancement: A new enhancement tool for seismic data
Authors: A. Rashed Mohamed , Atef Ali H. 
Published: July 2020

Abstract
Virtual resolution enhancement (VRE) is a new poststack cosmetic tool that can be applied to different types of seismic data. VRE emphasizes major reflections, enhances temporal resolution of seismic events, and suppresses reverberation noise, leading to better visualization of the entire seismic data. VRE is based on simple mathematical rule, and its parameters can be tweaked to suite the vast variety of seismic data available today. Although VRE does not reveal new or hidden features on seismic section, it significantly enhances the existing ones, which improves the interpretation and assists automatic horizon picking process. The only disadvantage of VRE is the long computational time. However, given the giant advances in the computational power and speed expected in the near future, this problem should be negligible. Tests conducted on seismic sections, collected from different regions in the world and went through different data acquisition and processing routines, prove the effectiveness of the VRE procedure.
Thermodynamic Theory of Diffusion and Thermodiffusion Coefficients in Multicomponent Mixtures
Authors: Shapiro Alexander A. 
Published: July 2020

Abstract
Transport coefficients (like diffusion and thermodiffusion) are the key parameters to be studied in non-equilibrium thermodynamics. For practical applications, it is important to predict them based on the thermodynamic parameters of a mixture under study: pressure, temperature, composition, and thermodynamic functions, like enthalpies or chemical potentials. The current study develops a thermodynamic framework for such prediction. The theory is based on a system of physically interpretable postulates; in this respect, it is better grounded theoretically than the previously suggested models for diffusion and thermodiffusion coefficients. In fact, it translates onto the thermodynamic language of the previously developed model for the transport properties based on the statistical fluctuation theory. Many statements of the previously developed model are simplified and amplified, and the derivation is made transparent and ready for further applications. The

determining parameters: the emission functions and the penetration lengths. The transport coefficients are expressed in terms of these parameters. These expressions are much simplified based on the Onsager symmetry property for the phenomenological coefficients. The model is verified by comparison with the known expressions for the diffusion coefficients that were previously considered in the literature.

The Dramatization of Emotions inIliad24.552–658
Authors: Xian Ruobing 
Published: July 2020

AbstractThis article argues that the episode inIl. 24.552–658 involving Achilles and Priam brings out the hero’s ability to control his emotions – even if he did lose them momentarily – by means of his calculation of what will come next. This interpretation fits the compositional structure of the epic, whose closure is highlighted by the hero’s dramatized emotions in his encounter with the Trojan king.

Authors: Teixeira Paulo E. P. , Zehry Hanan I. , Chaudhari Swapnali , Dipietro Laura , Fregni Felipe 
Published: July 2020

Abstract

Background and aims
Pain is a disabling symptom in knee osteoarthritis (KOA) and its underlying mechanism remains poorly understood. Dysfunction of descending pain modulatory pathways and reduced pain inhibition enhance pain facilitation in many chronic pain syndromes but do not fully explain pain levels in chronic musculoskeletal conditions. The objective of this study is to explore the association of clinical variables with pain intensity perception in KOA individuals with varying levels of Conditioned Pain Modulation (CPM) response.

Methods
This is a cross-sectional, exploratory analysis using baseline data of a randomized clinical trial investigating the effects of a non-invasive brain stimulation treatment on the perception of pain and functional limitations due to KOA. Sixty-three subjects with KOA were included in this study. Data on pain perception, mood perception, self-reported depression, physical function, quality of life, and quantitative sensory testing was collected. Multiple linear regression analysis was performed to explore the association between the clinical variables with pain perception for individuals with different levels of CPM response.

Results
For KOA patients with limited CPM response, perception of limitations at work/other activities due to emotional problems and stress scores were statistically significantly associated with pain scores, F(2, 37) = 7.02, p < 0.01. R-squared = 0.275. For KOA patients with normal CPM response, general health perception scores were statistically significantly associated with pain scores, F(1, 21) = 5.60, p < 0.05. R-squared = 0.2104. Limitations of this study include methodology details, small sample size and study design characteristics.

Conclusions
Pain intensity perception is associated differently with clinical variables according to the individual CPM response. Mechanistic models to explain pain perception in these two subgroups of KOA subjects are discussed.
Disclosure of Medical Confidentiality in Criminal Proceedings and Criminal Liability of a Doctor
Authors: Plebanek Ewa 
Published: July 2020

Abstract
The paper is devoted to the conflict between the duty to protect medical confidentiality and the interests of justice in criminal proceedings and substantive criminal law. The article contains considerations on medical confidentiality in relation to the legal and social obligation to notify authorities on the commission of a criminal act, as well as the maintenance of medical confidentiality in evidence proceedings in a situation where a doctor acts as a witness (taking into account the issues of protection of the so-called psychiatric secrecy and the secrecy of the doctor assisting the accused as regards the patient’s statements concerning the commission of a criminal act). A situation in which the obligation to keep medical secrecy limits the possibility for the depositary to exercise the right of defence is also analysed. In addition to proposals for resolving the presented conflict-of-law situations, the issue of attributing criminal liability to a doctor for the offence of not informing law enforcement authorities about the commission of a prohibited act (Article 240 paragraph 1 of the Penal Code) and the offence of disclosing professional secrecy against the provisions of the Act (Article 266 paragraph 1 of the Penal Code) in the presented conflict-of-law situations is considered.
The Professional Secrets of a Sexologist from the Perspective of Ethical and Legal Dilemmas: A Case Study
Authors: Kmieciak Błażej 
Published: July 2020

AbstractOver the past few years, the topic of sexual violence has repeatedly returned in social discussions. This is an issue that on one hand is shocking. On the other hand, however, this topic is associated with the emergence of interest, which causes the emergence of numerous dilemmas, questions and doubts. Analyzing the problem of sexual violence, very often (rightly) we focus on the victim. We wonder how we can give him/her advice, support and help. Securing the rights of victims is key here. The emergence of appropriate procedures is particularly important in a situation where there is information about a paedophilia crime.The protection of children’s rights has recently been a key area of interest in Poland: media, journalists, social activists and scientists. Emerging information on the sexual exploitation of children by public trust professionals is a constant challenge that aims to increase the level of safety of the smallest citizens. In the contexts discussed here, information about the perpetrator of a sexual crime appears from time to time. Inevitably, we may encounter a question about the past of a person suspected of sexual violence. Sometimes, public opinion gets information according to which the person has undergone therapy or treatment.This situation causes the inevitable conflict to arise in these situations. On the one hand, we have the priceless and especially well-placed child’s right to protection against violence. On the other hand, however, we can see the emerging problem of the protection of the secrecy of the therapeutic relationship, in which the participant was a person suspected of committing a paedophilia crime. This topic is of particular importance in the context of sexologists’ profession. From a legal and medical perspective, this is a special profession. Are its representatives obliged to maintain special confidentiality? Can they give up the principle of therapeutic confidentiality in certain situations? Perhaps there are situations in which they are legally obliged to the above exemptions. What should the scenario of the sexologist’s activities be like when ethical and legal norms collide?The proposed article will attempt to answer these questions. This action will be based on a case study.

Authors: Dwivedi Aparna , Maru Kavita , Sharma Aakash 
Published: July 2020

Introduction. The interocclusal registration materials record the occlusal relationship between the natural and /or artificial teeth for planning an occlusal rehabilitation in removable and fixed partial dentures.
Aim and objectives. The aim of this in vitro study was to evaluate and compare the accuracy and the three dimensional stability offered by three different types of interocclusal recording materials at storage time intervals of 1 hour and 24 hours.
Methods. Three commercially available interocclusal recording materials were used - Group I - Polyether bite registration paste (Ramitec), Group II- Polyvinylsiloxane bite registration material (Imprint), Group III- Bite registration wax (Maarc).The test was carried out using an epoxy resin model. A total of 30 samples were made with each group consisting of ten samples. Three dimensional measurements were carried out by using 3D-Coordinate measuring machine (CMM) at time intervals of 0-1 hour and 0-24 hours in X, Y and Z- axis.
Results. Twelve readings were obtained for three axes (4 readings for each sample at 1 axis) and the averages of these four values were noted for a particular axis (X/Y/Z). Statistical analysis was performed using analysis of variance (ANOVA) for comparison among the groups and then Tukey’s honestly significant difference (HSD) tests was performed for comparison among groups at the 0.05 level of significance.
Conclusion. Polyvinylsiloxane was dimensionally the most stable material followed by polyether and finally bite registration wax. Dimensional accuracy and stability is influenced by both “material” and “time” factors.
