Authors: Ülgey Ayşe , Pehlivan Sibel Seçkin , Demir Ömer Faruk 
Published: October 2020

AbstractBackground Thoracic surgery is one of the most painful surgeries. Effective analgesia is important in postoperative pain management. In this study, we aimed to compare the two new fascial block techniques.Methods A total of 107 patients who underwent thoracic surgery between October 2018 and November 2019 were retrospectively evaluated. The study included 59 patients in the serratus anterior plane block (SAPB) group and 48 patients in the erector spinae plane block (ESPB) group. Both groups were administered 30 mL of 0.25% bupivacaine and their morphine consumption was evaluated by a patient-controlled analgesia (PCA) method during the 2nd, 6th, 12th, 24th, and 48th postoperative hours. Pain was measured with the visual analog scale (VAS). Intraoperative mean arterial pressure (MAP) and heart rate (HR) were recorded.Results During the first 24 hours, VAS values were significantly lower in the ESPB group (p < 0.05). Moreover, morphine consumption was significantly lower in the ESPB group in the 24th and 48th hours (p < 0.05). Intraoperative remifentanil consumption was also significantly lower in the ESPB group (p < 0.05). Intraoperative MAP in the ESPB group was found to be significantly lower after the 4th hour. HR was similar in both groups.Conclusion ESPB was more effective compared with SAPB in postoperative thoracic pain management.

Published: October 2020

AbstractThe anterior tibial artery (ATA) is the most critical anatomical structure at risk at the distal border of the posterolateral approach to the tibial plateau. This study aimed to use available lower extremity digital subtraction angiography (DSA) images to determine the distal safe limit of this approach by measuring the distance from the tibial joint line to the ATA where it pierces the interosseous membrane. Tibial plateau mediolateral width (TP-ML-W) and the perpendicular distances from the ATA to the tibial joint line and fibular head were measured on DSA images in 219 lower extremities. To normalize the distances according to the tibial dimensions, each distance was divided by the TP-ML-W, and a ratio was obtained. Popliteal artery branching pattern was categorized according to the classification proposed by Kim et al. Comparative analysis between right and left extremities, genders, and anatomical variations were performed. There were 102 male and 26 female subjects with a mean age of 60.7 ± 15.7 years (range, 17–92 years). Ninety-one subjects had bilateral lower extremity DSA; thus, a total of 219 extremities were analyzed. The TP-ML-W was wider in male (78.3 ± 7.0) than female (70.5 ± 7.3) subjects (p = 0.001). The ATA coursed through the interosseous membrane at 50.9 ± 6.9 mm (range, 37.4–70.2 mm) distal to the tibial plateau joint line, and it was 66.5 ± 7.2% of the TP-ML-W. The ATA coursed through the interosseous membrane at 36.5 ± 6.0 mm (range, 21.9–53.8 mm) distal to the fibular head, and it was 47.7 ± 6.6% of the TP-ML-W. All measured variables were similar between the regular branching pattern of the popliteal artery (type 1A) and other observed variations among male subjects. The safe length of dissection in the posterolateral approach is average 66.5% (range, 45.7–86.7%) of the TP-ML-W. This ratio is valid for both genders. The use of a ratio instead of a distance, which is subject to personal variations, seems to be more logical and practical for planning this surgery, but the wide range should still not be ignored.

Abstract
Background Rapid deployment aortic valve replacement (RDAVR) has emerged as an alternative to conventional aortic valve replacement. This single-center study retrospectively analyzed clinical outcomes and hemodynamic performance of the Perceval S (LivaNova) and Intuity Elite (Edwards LifeSciences) rapid deployment valves (RDVs) in a propensity score matched patient cohort.
Methods A total of 372 consecutive patients with symptomatic aortic valve stenosis underwent RDAVR between 2012 and 2018 at our institution. The Intuity Elite (INT group) and Perceval S (PER group) were implanted in 251 and 121 patients, respectively. After 1:1 propensity score matching for relevant preoperative comorbidities, 107 patient pairs were compared with respect to relevant perioperative data including hemodynamic parameter, postoperative pacemaker implantation, and 30-day all-cause mortality.
Results Propensity score matching resulted in balanced characteristics between groups. Cardiopulmonary bypass and aortic cross-clamp time did not differ between groups, but more patients in the INT group received coronary artery bypass grafting compared with the PER group (56 vs. 42%; p = 0.055). Thirty-day mortality (4.7 vs. 2.2%) and need for permanent pacemaker implantation (7 versus 4.4%) were comparable between the INT and PER groups for isolated AVR and also for combined procedures, respectively. Cerebrovascular events showed comparable low rates for both RDVs (INT group [1.9%] vs. PER group [2.8%]). Indexed effective orifice area was higher in the INT group (0.90 vs. 0.82 cm2/m2) and coupled to a lower peak (17 ± 7 vs. 22 ± 8) and mean (10 ± 5 vs. 12 ± 4) pressure gradients compared with the PER group.
Conclusions Our propensity score analysis in AVR patients showed good hemodynamic characteristics with comparable 30-day mortality rate and complications rates for both investigated RDVs.

Published: October 2020

AbstractThis review deals with the emerging coronavirus disease 2019 (COVID-19) epidemic summarizing current and evolving medical management in India, and also indicating future directions in the light of possible resurgence of this disease as pandemic as well as prospective biological threats resulting from acts of bioterrorism. Clinical accounts both in published or prepublication reports from the frontline epicenters were used, incorporating the evolving flux in guidelines and current controversies, expressed not only in Print media but also video-webinars and conferences constantly in progress. Rather than presenting hard conclusions from the few randomized controlled trials, less formal clinical impressions have been incorporated in the review as it is felt that at this stage of the COVID-19 battle, such data are relevant! Periodic rewriting on this subject is in our opinion, therefore, eminently desirable (Box format used to allow this). Apart from the respiratory crisis aggravated by cytokine storms, reference is made to the cardiovascular, neurological, renal, gastrointestinal, and cutaneous features, these generalized manifestations being related to the widespread distribution of angiotensin-converting enzyme-2 receptors in the body as well as to the acute inflammatory hypercoagulopathy and disseminated intravascular coagulation typified by hyperacute levels of acute phase reactants as well as the effects of hypoxia-overt or silent!

Authors: Vital Luísa , Vidinha Vitor , Neves Nuno , Negrão Pedro 
Published: October 2020

ResumoA apófise supracondilar (ASC) é uma proeminência óssea que tem origem na face anteromedial do úmero distal com projeção inferior e que, apesar de habitualmente assintomática, pela relação com as estruturas adjacentes pode causar sintomatologia. Descrevemos o caso de uma mulher de 42 anos, com queixas álgicas irradiadas do cotovelo à mão, com 6 meses de evolução. Ao exame objetivo, a paciente apresentava um déficit sensorial no território do nervo mediano e diminuição da força de preensão. Foram realizadas radiografias do úmero distal nas quais era visível uma espícula óssea, e na ressonância magnética era evidente o espessamento do epineuro do nervo mediano. A eletromiografia apresentou uma desmielinização axonal grave do nervo mediano proximal ao cotovelo. Foi diagnosticada uma compressão do nervo mediano por uma ASC. A paciente foi submetida à cirurgia e 1 ano pós-operatório apresentou recuperação clínica total. A ASC é uma causa rara, mas possível e tratável da compressão alta do nervo mediano.
Paralinguistic resources in persuasive business communication in
English and Spanish

Published: October 2020

Abstract
This study presents the results of research
carried out to unveil how nonverbal paralinguistic signs are used in
persuasive business communication in two parallel Spanish/British
English corpora of TV entrepreneurial pitches. A specific analytic
method has been developed to identify discrete nonverbal signs
together with their function in the communicative acts studied, to
ascertain frequency of sign use and the influence L1 and gender may
exert on the quantity, type, and function of such devices. Results
show that of all devices (i.e., volume, tone, speed,
sound-lengthening, emotional reactions, quasi-lexical elements, and
pauses), pauses are the most profusely used (65% of the cases),
although both variables (L1 and gender) have a bearing on the
socio-communicative variations of paralinguistic devices among
different subjects.
Co-regulating algorithmic disclosure for digital platforms
Authors: Di Porto Fabiana , Zuppetta Marialuisa 
Published: October 2020

ABSTRACTWith digital platforms gaining dominant intermediating role and exerting regulatory functions vis-à-vis small and medium-sized enterprises (SMEs) through algorithms, EU institutions have started considering to rely on their analytical capacity to regulate the myriads of market transactions occurring within and through them (so-called platform-to-business, or P2B transactions). Most of the time, the EU suggests recurring to light-tough disclosure duties. Hence, the European model falls short in rebalancing information asymmetry and unequal bargaining power plaguing the SMEs. In practice, the EU model consists either in pure delegation of self-regulatory powers (codes of conduct) or non-enforceable co-regulatory schemes (with technical standards established by the platforms themselves). Other models have been suggested that rely on the regulator's access to the platform's data (so called savvy and data-delegated options). These governance models present several limitations, making the platforms' role as regulatory intermediators little credible. In this scenario, the paper purports that a third option should be considered. In particular, to tackle the multifaceted risks associated with algorithmic decisions by digital platforms, while at the same time avoiding stifling innovation, it makes three suggestions: (1) also information disclosures should be done by an algorithm; (2) that is pre-tested in a co-regulatory process, that involves the regulator and stakeholders; and (3) enforced through legal and other empowerment tools, rather than sole fines.

This report describes the first CCM key comparison of realizations of the kilogram definition based on the fixed numerical value of the Planck constant, which came into force on 20 May 2019. The objectives were to determine the level of agreement between realizations of the kilogram using Kibble and joule balances and the X-ray crystal density (XRCD) method and to provide input for the calculation of the first "consensus value" of the kilogram. The consensus value will serve as the basis for an internationally coordinated dissemination of the kilogram which will continue until sufficient agreement between realization experiments has been achieved.
The comparison was organized by the BIPM and had seven participants. The BIPM, KRISS, NIST and NRC operated Kibble balances, the NIM used a joule balance and the NMIJ and the PTB participated using 28Si spheres, the masses of which were determined with the XRCD method. These realization methods were used to calibrate 1 kg mass standards under vacuum. The standards were sent (in air) to the BIPM where they were compared under vacuum with each other and with BIPM Pt-Ir working standards. The latter were calibrated (in air) traceable to the International Prototype of the Kilogram (IPK), the mass of which served as the definition of the kilogram until 20 May 2019.
The results of the weighings at the BIPM together with the measurement results communicated by the participants allowed comparison of the values attributed to mass standards of 1 kg using the participating realization experiments. The level of agreement between mass determinations with the realization experiments and the BIPM as-maintained mass unit, traceable to the Planck constant through the mass of the International Prototype of the Kilogram can also be deduced.

Published: October 2020

Abstract
Solution-processed photodetectors have emerged as the next generation of sensing technology owing to their ease of integration with electron devices and of tuning photodetector performance. Currently, novel self-powered photodetectors without an external power source, for use in sensing, imaging and communication, are in high demand. Herein, we successfully developed a self-powered photodetector based on a novel solution-processed p-NiO/n-CdS:Al heterojunction, which shows an excellent current rectification characteristic ratio of up to three orders in the dark and distinctive photovoltaic behavior under light illumination. The complete solution synthesis route followed the development of CdS:Al thin films on ITO substrates by chemical bath deposition and NiO thin films by the sol-gel route. Optical absorption data revealed that NiO is more active in the UV region and CdS:Al has a majority of absorption in the visible region; so, upon light illumination, the effective separation of photogenerated carriers produces fast photodetection in the UV–visible region. The photoresponsivity values of the fabricated device were calculated to be 55 mA W−1 and 30 mA W−1 for UV and visible illumination, respectively. Also, the device has a fast rise and decay photoresponse speed at zero bias voltage, due to the self-driven photovoltaic effect which makes this heterojunction a self-powered device. This complete solution and new method of fabrication make it possible to combine different materials and flexible substrates, enhancing its potential applications in photodetectors, optoelectronic devices and sensors.

Published: October 2020

Abstract

Objective: Our objective is to study how to obtain features which can reflect the continuity and internal dynamic changes of electroencephalography (EEG) signals and study an effective method for fatigued driving state recognition based on the obtained features. Approach: A method of EEG signalfeature extraction based on functional data analysis is proposed. Combined with kernel principal component analysis method, the obtained features are applied to the recognition of driver fatigue state, and a corresponding recognition model of fatigued driving state is constructed. Main results: The recognition model is tested on the real collected driver fatigue EEG signals by selecting a suitable classifier. The test results show that the proposed driver fatigue state recognition method has good recognition effect, especially on the classifier based on decision tree, with an average accuracy of 99.50%. Significance: The extracted features well reflect the continuityand internal dynamic changes of the EEG signals, and it is of great significance and application value to study an effective method of fatigued driver state recognition based on the features.

Published: October 2020

Abstract
In this paper, a 3D force feedback system featuring a 2D-gimbal mechanism incorporated with two bidirectional magneto-rheological actuators (BMRAs) and a linear magnetorheological brake (LMRB) is designed, manufactured and experimentally tested. Firstly, a configuration of the 3D force feedback system is introduced, and then the BMRAs and the LMRB for force feedback are proposed and experimentally evaluated. Based on experimental results, experiment-based models of the BMRAs and LMRB are identified. A controller is then proposed for the 3D force feedback system. In order to evaluate performance of the proposed 3D force feedback system, a prototype of the proposed force feedback system is manufactured and experimental apparatus for force feedback testing is set up. Experimental works on performance testing of the force feedback system is then conducted and the results are presented and evaluated.

Published: October 2020

Abstract
A compact all optical 4-bit digital-to-analog converter (DAC) based on 2D photonic crystals is proposed to operate in the III transmission window 1550 nm of optical communication systems. The DAC consists of a photonic crystal ring resonator whose operation is based on the nonlinear Kerr effect. The overall operation of the proposed DAC is analyzed using the finite difference time domain method and plane wave expansion method. The total footprint of the proposed structure is 1150 µm2 with silicon rods of refractive index equal to 3.4641 placed in an air substrate with a 2D square lattice, exhibiting an insertion loss of −11 dB and absolute error of 2.79% which is suitable for photonic integrated circuits.
The bar and spiral arms in the Milky Way: structure and kinematics
Authors: Shen Juntai , Zheng Xing-Wu 
Published: October 2020

Abstract
The Milky Way is a spiral galaxy with the Schechter characteristic luminosity L
*, thus an important anchor point of the Hubble sequence of all spiral galaxies. Yet the true appearance of the Milky Way has remained elusive for centuries. We review the current best understanding of the structure and kinematics of our home galaxy, and present an updated scientifically accurate visualization of the Milky Way structure with almost all components of the spiral arms, along with the COBE image in the solar perspective. The Milky Way contains a strong bar, four major spiral arms, and an additional arm segment (the Local arm) that may be longer than previously thought. The Galactic boxy bulge that we observe is mostly the peanut-shaped central bar viewed nearly end-on with a bar angle of ∼ 25° – 30° from the Sun-Galactic center line. The bar transitions smoothly from a central peanut-shaped structure to an extended thin part that ends around R ∼ 5 kpc. The Galactic bulge/bar contains ∼ 30% – 40% of the total stellar mass in the Galaxy. Dynamical modelling of both the stellar and gas kinematics yields a bar pattern rotation speed of ∼ 35 – 40 km s−1kpc −1, corresponding to a bar rotation period of ∼ 160 – 180 Myr. From a galaxy formation point of view, our Milky Way is probably a pure-disk galaxy with little room for a significant merger-made, “classical” spheroidal bulge, and we give a number of reasons why this is the case.
A tale of planet formation: from dust to planets
Authors: Liu Beibei , Ji Jianghui 
Published: October 2020

AbstractThe characterization of exoplanets and their birth protoplanetary disks has enormously advanced in the last decade. Benefitting from that, our global understanding of the planet formation processes has been substantially improved. In this review, we first summarize the cutting-edge states of the exoplanet and disk observations. We further present a comprehensive panoptic view of modern core accretion planet formation scenarios, including dust growth and radial drift, planetesimal formation by the streaming instability, core growth by planetesimal accretion and pebble accretion. We discuss the key concepts and physical processes in each growth stage and elaborate on the connections between theoretical studies and observational revelations. Finally, we point out the critical questions and future directions of planet formation studies.

Abstract
We investigate the clustering transition undergone by an exemplary random constraint satisfaction problem, the bicoloring of k-uniform random hypergraphs, when its solutions are weighted non-uniformly, with a soft interaction between variables belonging to distinct hyperedges. We show that the threshold α
d(k) for the transition can be further increased with respect to a restricted interaction within the hyperedges, and perform an asymptotic expansion of α
d(k) in the large k limit. We find that
