Published: January 2020

Objective:
To evaluate the usefulness of histogram analysis of stretched exponential model (SEM) on diffusion-weighted imaging in evaluating clinically significant prostate cancer (CSC).

Methods:
A total of 85 patients with prostate cancer underwent 3 T multiparametric MRI, followed by radical prostatectomy. Histogram parameters of the tumor from the SEM [distributed diffusion coefficient (DDC) and α] and the monoexponential model [MEM; apparent diffusion coefficient (ADC)] were evaluated. The associations between parameters and Gleason score or Prostate Imaging Reporting and Data System v. 2 were evaluated. The area under the receiver operating characteristics curve was calculated to evaluate diagnostic performance of parameters in predicting CSC.

Results:
The values of histogram parameters of DDC and ADC were significantly lower in patients with CSC than in patients without CSC (p &lt; 0.05), except for skewness and kurtosis. The value of the 25th percentile of α was significantly lower in patients with CSC than in patients without CSC (p = 0.014). Histogram parameters of ADC and DDC had significant weak to moderate negative associations with Gleason score or Prostate Imaging Reporting and Data System v. 2 (p &lt; 0.001), except for skewness and kurtosis. For predicting CSC, the area under the curves of mean ADC (0.856), 50th percentile DDC (0.852), and 25th percentile α (0.707) yielded the highest values compared to other histogram parameters from each group.

Conclusion:
Histogram analysis of the SEM on diffusion-weighted imaging may be a useful quantitative tool for evaluating CSC. However, the SEM did not outperform the MEM.

Advances in knowledge:
Histogram parameters of SEM may be useful for evaluating CSC.
Anticipatory Consumptions
Authors: Guo Liang 
Published: January 2020

Mental simulations such as anticipatory and/or retrospective emotions can yield higher weight for a delayed consequence than for current well-being (i.e., negative devaluing). In this research, we investigate the behavioral and welfare implications of negative devaluing for intertemporal consumptions in an intrapersonal game. Our general framework accounts for two distinctions: desired versus undesired consumptions, and naive versus sophisticated beliefs about future selves’ preferences. Naive people procrastinate desired consumptions and preproperate undesired ones. The behavior of sophisticated people generally exhibits a cyclical pattern. Sophistication may either mitigate or exacerbate the time-inconsistency problem, and hence may improve or undermine long-run welfare, depending on the valence and the units of consumptions and on whether consumptions are tied consecutively. In addition, our comparative statics analysis generates surprising results with respect to the impacts of decision parameters (e.g., deadline, consumption units). We also discuss implications for targeted pricing, product design, promotion strategies, and savings. This paper was accepted by Matthew Shum, marketing.
Integrating the PV-Diesel Hybrid System for Reliability Improvement in Distribution System
Authors: Myint Cho Cho , Lin Ohn Zin , Ei Aung Soe Soe 
Published: January 2020

In Myanmar, as the main power generation is hydro power generation. the utility cannot supply sufficient power to customers during the dry season. Besides interruptions occur frequently due to aging system and lack of prospered protection. Therefore, reliability is an urgent issue in Myanmar. As a result of unbalance between generation and load, the distribution system is getting poor voltage profile, instability and high power losses in high load condition. According to network characteristics, the failure of a component always leads to consequence interruption in a radial distribution system. Therefore, it is a must consideration to mitigate these challenges to enhance the system reliability. There are many techniques to solve the reliability problems such as reclosers, switching devices (manual and automated switches), system reconfiguration, feeder re-conducting and integration of distributed generation (DG). In this paper, system reliability assessment is evaluated in detail with the integration of the distributed generation such as PV-Diesel Hybrid System. The location of DG is chosen according to the expected energy not supply (EENS) and the voltage drop in proposed system. Next, the optimal sizing of DG is chosen depends on the penetration level of generator. Reliability indices can be evaluated depending on the failure rate(λ), repair time(r) and annual outage time(U) in Electrical Transient and Analysis Program (ETAP) software. The case study of this thesis is carried out in 33/11 kV network which is connected Kyatminton Substation, Kyaukse, Middle Myanmar.
Intraoperative neuromonitoring in spine deformity surgery: modalities, advantages, limitations, medicolegal issues – surgeons’ views
Authors: Biscevic Mirza , Sehic Aida , Krupic Ferid 
Published: January 2020

In spine deformity surgery, iatrogenic neurologic injuries might occur due to the mechanical force applied to the spinal cord from implants, instruments, and bony structures, or due to ischemic changes from vessel ligation during exposure and cord distraction/compression during corrective manoeuvres. Prompt reaction within the reversible phase (reducing of compressive/distractive forces) usually restores functionality of the spinal cord, but if those forces continue to persist, a permanent neurological deficit might be expected. With monitoring of sensory pathways (dorsal column–medial lemniscus) by somatosensory-evoked potentials (SSEPs), such events are detected with a sensitivity of up to 92%, and a specificity of up to 100%. The monitoring of motor pathways by transcranial electric motor-evoked potentials (TceMEPs) has a sensitivity and a specificity of up to 100%, but it requires avoidance of halogenated anaesthetics and neuromuscular blockades. Different modalities of intraoperative neuromonitoring (IONM: SSEP, TceMEP, or combined) can be performed by the neurophysiologist, the technician or the surgeon. Combined SSEP/TceMEP performed by the neurophysiologist in the operating room is the preferable method of IONM, but it might be impractical or unaffordable in many institutions. Still, many spine deformity surgeries worldwide are performed without any type of IONM. Medicolegal aspects of IONM are different worldwide and in many cases some vagueness remains. The type of IONM that a spinal surgeon employs should be reliable, affordable, practical, and recognized by the medicolegal guidelines.Cite this article: EFORT Open Rev 2020;5:9-16.

Numerically stable formulation of Mie theory for an emitter close to a sphere
Authors: Majic Matt , Le Ru Eric C. 
Published: January 2020

Numerical implementations of Mie theory make extensive use of spherical Bessel functions. These functions are, however, known to overflow/underflow (grow too large/small for floating point precision) for orders much larger than the argument. This is not a problem in applications such as plane wave excitation, as the Mie series converge before these numerical problems arise. However, for an emitter close to the surface of a sphere, the scattered field in the vicinity of the sphere is expressed as slowly converging series, with multipoles up to order 1000 required in some cases. These series may be used to calculate experimentally relevant quantities such as the decay rate of an emitter near a sphere. In these cases, overflow/underflow prevents any calculation in double precision using Mie theory, and alternatives are either computationally intensive (e.g., arbitrary precision calculations) or not accurate enough (e.g., the electrostatics approximation). We present here a formulation of Mie theory that overcomes these limitations. Using normalized Bessel functions where the large growth/decay is extracted as a prefactor, we re-express the Mie coefficients for scattering by spheres in a normalized form. These normalized expressions are used to accurately compute the series for the electric field and decay rate of a dipole emitter near a spherical surface, in cases where the Mie coefficients would normally overflow before any degree of accuracy can be obtained.

Published: January 2020

We present two kinds of mode-selective-coupler-based ultrafast radially polarized lasers delivering switchable wavelengths and pulsewidths. One is a linear-cavity fiber laser mode locked in the 1.5 µm region, which produces not only wavelength-agile radially polarized pulses in the spatial domain, but also switchable femtosecond and picosecond pulses in the temporal domain. The other one is a nonlinear-polarization-rotation-technique-assisted passively mode-locked fiber ring laser in the 1.0 µm region, presenting an ideal broadband spectral switching with picosecond radially polarized pulses output. The presented fiber lasers offer a type of compact laser source, enabling a flexible option for radially polarized beams in spectral and temporal domains.

Abstract
The objective of the present study was to compare the effect of rhamnolipids on the microbial biomass content and the activity of dehydrogenases (DHA), acid phosphatase (ACP), alkaline phosphatase (ALP), and urease (URE) in soil contaminated with two types of coal tar creosote: type C and type GX-Plus. The experiment was carried out on samples of sandy clay loam under laboratory conditions. Coal tar creosote was added to soil samples at a dose of 0 and 10 g·kg−1 DM, along with rhamnolipids at a dose of 0, 10, 100, and 1000 mg·kg−1 DM. The humidity of the samples was brought to 60% maximum water holding capacity, and the samples were incubated at 20°C. Microbial and biochemical parameters were determined on days 1, 7, 21, and 63. The obtained results demonstrated that the addition of rhamnolipids did not result in any significant changes in the activity of the determined parameters in the uncontaminated soil. However, it was observed that the application of these biosurfactants, particularly at the dose of 1000 mg·kg−1 DM, largely decreased the effect of coal tar creosote on the determined parameters. Moreover, the microbial biomass and the activity of ALP and URE were found to be the best indicator of bioremediation of soil contaminated with coal tar creosote.
Effects of foliar trichomes on the accumulation of atmospheric particulates in Tillandsia brachycaulos
Authors: Zhang Ruiwen , Zheng Guiling , Li Peng 
Published: January 2020

AbstractFoliar trichomes are specialized structures that have first contact with atmospheric particulate matter (PM), while their effects on PM accumulation are rarely investigated. In this study, epiphytic Tillandsia brachycaulos with foliar trichomes was investigated. Trichomes were removed artificially to investigate PM adsorption and resuspension. The results showed that the maximum PM (13.94±0.20 g•m-2) and natural PM content (10.65±1.10 g•m-2) on T. brachycaulos samples with foliar trichomes was significantly higher than those without foliar trichomes. After PM deposition on the leaf surface, more than 85% of PM was dispersed by wind in plants without trichomes, significantly higher than those with trichomes (30.2%). Therefore, the effects of foliar trichomes on PM were reflected not only on PM adsorption, but on PM resuspension. Foliar trichomes can decrease PM resuspension falling on the leaf surface and promote the accumulation of these particles.
On the singular value decomposition of (skew-)involutory and (skew-)coninvolutory matrices
Authors: Faßbender Heike , Halwaß Martin 
Published: January 2020

AbstractThe singular values σ > 1 of an n × n involutory matrix A appear in pairs (σ, {1 \over \sigma }). Their left and right singular vectors are closely connected. The case of singular values σ = 1 is discussed in detail. These singular values may appear in pairs (1,1) with closely connected left and right singular vectors or by themselves. The link between the left and right singular vectors is used to reformulate the singular value decomposition (SVD) of an involutory matrix as an eigendecomposition. This displays an interesting relation between the singular values of an involutory matrix and its eigenvalues. Similar observations hold for the SVD, the singular values and the coneigenvalues of (skew-)coninvolutory matrices.
The unwanted past and urban regeneration of Communist heritage cities. Case study: European Capitals of Culture (ECoC) Riga 2014, Pilsen 2015 and Wroclaw 2016
Authors: Turșie Corina 
Published: January 2020

Within the ECoC programme, it has been argued that the European dimension is most visible when the candidates reflect their own history as a part of European history, particularly when hinting at their involvement with the major ideologies of twentieth century, such as National Socialism or Communism. ECoC is about cities re-inventing their identities, re-narrating their history in a European context. But how should ex-communist cities deal with their unwanted past and narrate it in order to fit into the European dimension of the project? The focus of this investigation is on three ex-ECOCs from ex-Communist Europe, chosen for several reasons: geographical position (Central, Eastern/Northern European countries, ex-communist past, new membership of the European Union (since 2004), the year of holding the title (the two ECoC selection criteria exist since 2010). Using qualitative content analysis on a set of documents (application books, official web pages and ex-post evaluations) the study will offer an analysis of cities’ politics of memory and urban regeneration strategies.
A argumentação contrária aos Direitos Humanos em comentários em portais de informação: um olhar sobre a questão prisional
Authors: Brito Clebson Luiz de 
Published: January 2020

RESUMO:Parte de um trabalho mais amplo dedicado às representações discursivas sobre os Direitos Humanos, o presente artigo examina a argumentação contrária a esses direitos em comentários relativos a notícias sobre a questão prisional em portais de informação. Para isso, diferentes comentários foram coletados nos portais: G1, UOl e Terra, que são considerados os mais abrangentes, e posteriormente foram analisados a partir de uma abordagem teórica derivada da interação entre os estudos do discurso e os estudos da argumentação. O exame realizado revela, em última análise, procedimentos argumentativos que configuram uma espécie de retórica duplamente desumanizante, na medida em que os textos, atribuindo em geral ao outro uma condição não humana, se valem disso para sustentar ideias e incentivar ações típicas de pessoas embrutecidas por relações sociais violentas.
PALAVRAS-CHAVE: Direitos Humanos; argumentação; questão prisional; comentários em portais de informação.

ABSTRACT:Part of a broader work dedicated to the discursive representations about Human Rights, this article examines the argumentation contrary to these rights in comments, related to news about the prison issue, in news websites. To do that, different comments were collected in the websites: G1, UOl and Terra, which are considered the most comprehensive ones, and these texts were subsequently analyzed based on a theoretical framework derived from the interaction between discourse studies and argumentation studies. The examination reveals, ultimately, argumentative procedures that constitute a double dehumanizing rhetoric, since the texts, generally attributing to the other a non-human condition, use this to support ideas and encourageactions typical of people brutalized by violent social relations.

ABSTRACT: Researching the insertion of digital information and communication technologies in the formative contexts involves problematizing teachers and students’ perceptions, appropriations and meanings about the issue. This text sought to identify the Brazilian scientific productions (theses and dissertations) regarding digital literacy in teacher education, between the years 2010 to 2018. We used the systematic review as a methodological procedure, with the help of the Parsifal software. We scored the following equations to verify the work: which research objectives do these productions reveal? What perspectives of digital literacy and what procedures and methodological instruments did the researchers adopt? What results of the digital literacy processes worked on in the training of teachers were revealed? As results, we validated 37 works, which point out the settings of training proposals with uses of digital technologies that seek to respond to the new social dynamics that student-teachers need to be able to. According to the research works found, the initial or continued training courses have lent themselves to insert the digital technologies, but the possibilities of uses are still many.
