Published: February 2020

A thermally tuned multi-channel interference widely tunable semiconductor laser is designed and demonstrated, for the first time to our knowledge, that realizes a tuning range of more than 45 nm, side-mode suppression ratios up to 56 dB, and Lorentzian linewidth below 160 kHz. AlGaInAs multiple quantum wells (MQWs) were used to reduce linewidth, which have a lower linewidth enhancement factor compared with InGaAsP MQWs. To decrease the power consumption of micro-heaters, air gaps were fabricated below the arm phase sections. For a 75 μm long suspended thermal tuning waveguide, about 6.3 mW micro-heater tuning power is needed for a

round-trip phase change. Total micro-heater tuning power required is less than 50 mW across the whole tuning range, which is lower than that of the reported thermally tuned tunable semiconductor lasers.

Gallium nitride (GaN)-based light-emitting diodes (LEDs) are important for lighting and display applications. In this paper, we demonstrate green-emission (512 nm) InGaN quantum dot (QD) LEDs grown on a c-plane sapphire substrate by metal-organic chemical vapor deposition. A radiative lifetime of 707 ps for the uniform InGaN self-assembled QDs is obtained by time-resolved photoluminescence measurement at 18 K. The screening of the built-in fields in the QDs effectively improves the performance of QD LEDs. These high quantum efficiency and high temperature stability green QD LEDs are able to operate with negligible efficiency droop and with current density up to

Expanding comics theory to account for interactivity: A preliminary study
Authors: Neo Tiffany , Mitchell Alex 
Published: February 2020

Abstract
Comics are a medium distinct from and yet tied to other forms of storytelling. A rich body of theory exists on the nature of the medium, its narrative techniques and the visual language unique to it. In light of the increasing interest in digital interactive technologies, however, there is a need to examine how the current theoretical understanding of comics is complicated by interactivity, as has been studied for other media such as text-based stories and games. This article outlines an exploratory study that introduced interactions, reminiscent of the Quick-Time Events found in games, into a four-panel comic. The results of this study, based on exposure to experimental prototypes, followed by retrospective protocol analysis and qualitative interviews, begin to shed light on various theoretical implications of including interactivity. These include empirical support that the notion of comics as an interconnected multiframe remains valid in the context of interactivity; the relative hierarchy between the iconic image and interactive elements; functions of interactivity within the comic form; the role of challenge; and the role of fluency and learning. These findings highlight possible ways in which the inclusion of interactivity expands current theory regarding the comic form, serving as openings for future theory-building.
On polysemiotic interactions, visual paratexts and image-specific translation in comics: The case of Rodolfo Santullo and Matías Bergara's Dengue
Authors: Fraser Benjamin 
Published: February 2020

Abstract
The practice of translation in comics has received relatively little scholarly attention. This article focuses on translation decisions as they are carried out in the medium-specific interplay of words and images that constitutes the comics text. Using the case of Dengue (Santullo and Bergara) in both its Spanish (2012) and English (2015) versions, analysis explores how polysemiotic interactions, visual paratexts and image-specific translation inform the resulting graphic novel. Discussion centres on how the English version effects a significant thematic shift that is consistent across the cover art, frontmatter, chapter title pages, and individual panel rewordings.

Authors: Klaehn Jeffery 
Published: February 2020

Abstract
Norm Breyfogle (27 February 1960–24 September 2018) is widely recognized for his six years (1987–93) spent illustrating various Batman titles for DC Comics, most notably Detective Comics, Batman and Batman: Shadow of the Bat. He also illustrated several prestige edition one-shots set within the Batman narrative universe, including Batman: Birth of the Demon (1992), which he hand-painted, and the 'Elseworlds' stories, Batman: Holy Terror (1991), Batman: The Abduction (1998) and Batman: Dreamland (2000). In this interview, undertaken in 2007, he discusses his approach to cover design and interior art; the comic industry; how he came to work on Batman; his collaborations with writer Alan Grant; reflections on the character of Anarky; details on an unpublished three issue Anarky storyline involving East Timor and US arms sales to Indonesia; how Batman has changed over the decades; as well as his thoughts on how Jim Aparo, Marshall Rogers and Frank Miller drew Batman.
Meta models for intralogistics

Published: February 2020

Abstract
In industrial automation, adaptability is a key feature that can enhance the degree of autonomy in a plant sparing engineering months and costs. With the introduction of the service oriented architecture in control automation, a topology model is required to identify the vicinity relationships between the devices. Nowadays, due to the absence of the coupling between logistic aspects and control logic, the topology models are manually constructed which consequently affects the autonomy of the procedures generation. In this contribution, we introduce a concept to couple the logistics model with the devices abilities to generate product flow paths and procedures considering adaptable conditions.
Lessons Learned from an ACT-Based Physician-Delivered Weight Loss Intervention: A Pilot RCT Demonstrates Limits to Feasibility
Authors: Frayn Mallory , Carrière Kimberly , Knäuper Bärbel 
Published: February 2020

AbstractBackground: Acceptance and Commitment Therapy (ACT) interventions have shown to be effective in facilitating weight loss for emotional eaters, however, the lack of accessibility of these interventions limits their impact. The present study aimed to increase the accessibility of an ACT intervention for emotional eaters through delivery by physicians.Methods: This two-arm pilot randomized controlled trial tested the effectiveness and feasibility of a brief ACT intervention for emotional eaters compared with standard care at a weight loss clinic in Toronto, Canada. Primary outcomes were changes in weight and emotional eating. Treatment satisfaction was also assessed.Results: Participants in neither condition lost weight. Both conditions displayed decreases in emotional eating, but no condition interaction was found. Both patients and physicians reported high treatment satisfaction with the ACT intervention. However, there were high attrition rates and variability in intervention completion times.Conclusion: The ACT intervention led to reductions in emotional eating and was well received by patients and physicians alike. However, the present study identified high attrition as a limitation to the feasibility of this mode of intervention delivery. Future interventions may be more effectively delivered in primary care settings by encouraging further brevity and exploring delivery by other health professionals.

Published: February 2020

Objectives: The aim of this study was to perform morphometric analysis of arterial conduits harvested by harmonic scalpel in coronary artery bypass grafting (CABG) patients.
Methods: From 100 CABG patients, 200 arterial conduits—100 radial arteries (RAs) and 100 left internal thoracic artery (LITAs)—were harvested. The patients had similar characteristics (mean age, sex ratio, comorbidities, etc.). We divided the patients into 2 groups according to harvesting technique. In group 1, a harmonic scalpel was used in 50 patients for harvesting arterial conduits (50 LITA and 50 RA). In group 2, conduits were harvested using low-voltage electrocautery. To prevent side effects of clipping, all conduits in both groups remained in perfused condition until anastomosis. A 10-mm length of conduit was cut for transmission electron microscopy investigation. We calculated duration of harvesting, blood flow changes, and histopathologic changes of the conduits according to a vessel scoring system.
Results: In the harmonic scalpel group, we detected pathologic findings—corruption of endothelial integrity, subendothelial damage, and endothelial pathology—in 5 specimens (10%) (3 LITA [6%] and 2 RA [4%]). In group 2, pathologic findings were detected in 16 conduits (32%; 11 LITA, 22%, and 5 RA, 10%). Endothelial dissection, subendothelial disarrangement, cellular separation due to intercellular edema, and subadventitial hematoma were the main pathologic changes in the classic harvesting method. There was a significant difference between the groups (P = .001). Harvesting time of LITA was nearly similar in both groups: 26.9 ± 11.1 min (range 25-38) in group 1 and 21.3 ± 8.6 min (range 21-25) in group 2 (P = .049). RA harvesting time was significantly shorter with the harmonic scalpel technique (20.3 ± 3.9 versus 27.6 ± 5.4 min, P = .022). The blood flow of the conduits was similar, with no statistical difference for the 2 arterial conduits (LITA, P = .76; RA, P = .55).
Conclusion: In the learning curve period, the use of a harmonic scalpel is time consuming and presents some difficulties during the harvesting of conduits. According to our study results, however, the harmonic scalpel technique may be useful because of decreased pathology, including spasm. In our opinion, graft occlusion or thrombus as a life-threatening condition and endothelial dysfunction may decrease with the use of this alternative harvesting technique.
Functional Evolution of the Kernavė Hillforts in the Iron Age: New Intepretations of Old Data
Authors: Vengalis Rokas , Vėlius Gintautas 
Published: February 2020

This article explores the finds and post-excavation reports of earlier archaeological investigations in the five Kernavė hillforts. The detailed analysis of the assembled finds, discovered features and structures made it possible to revise and improve the prieviously suggested evolution model for the Kernavė hillforts. It reveals the evolution of the hillforts to have been much more complicated and that, over time, their function has changed rather significantly more than once. The finds recovered during earlier excavations were not classified into primary, secondary and de facto refuse. New examination of refuse – in this case, of pottery sherds, allowed for identification of single events, short-term activities and long-term settlement on the hillforts as well as distinct functional areas. The authors discuss whether the term “hillfortˮ is appropriate for use in scientific historiography. The issue of actual contemporaneity of the hilfforts in hilffort complexes is also raised.
Image copywriting : genres and methods of creating the image texts
Authors: Blynova N. , Polishko N. , Mykhailova A. 
Published: February 2020

The specificity of image copywriting, the features of storytelling as a method of writing image materials are considered. Image copywriting involves the creation of texts that shape and enshrine the image of the brand, the person and the service in the consumer’s mind. Historically, in Ukraine image texts were first circulated through the traditional and electronic media, and with the development of network communication an active functioning of such texts started on Internet, which proved its extraordinary effectiveness precisely when reaching the network audience.
At the same time, the text does not only emphasize the positive aspects of the institution, product or service, does not call for something to buy or order. This is its key difference from the Direct-Response copywriting materials. Image copywriting has much in common with such journalistic genres as: review, press release, interview, biography, invitation, expert opinion, media statement. In the web space, the most prominent examples of the implementation of the image copywriting is the section "About Us", which is mandatory for many companies' sites, and is obligatory for any resource “Home” page.Today, the most commercially viable way of writing image texts is storytelling. It was first approached in the early 2010s in the New York Times. Simply and unobtrusively speaking about yourself, the company and the product is the best way to establish a connection with the consumer and the market is. A professionally created story not only create big interest but also arouse empathy in the readers, who begin to agree with the author. The unobtrusive presentation of information leads to the goal set by marketers: it is up to the individual to decide how to treat the material. Today, special storytelling techniques are being developed and actively operating to help copywriters to create image text of high quality.Such materials increase the trust of the target audience to the object of the image campaign, have lasting effect and remarkable commercial results.
Site Effects of Onna during the 2009 L’Aquila (Central Italy) Seismic Sequence: Constraints on Bedrock Depth and 1D Local Velocity Structure from Aftershock Seismograms
Authors: Mele Giuliana , Rovelli Antonio , Fodarella Antonio , Mancini Marco 
Published: February 2020

ABSTRACTAfter the 2009 L’Aquila Mw 6.1 earthquake, particular attention was paid to the large difference of Mercalli–Cancani–Sieberg (MCS) macroseismic intensity between the nearby villages of Onna (9.5 MCS) and Monticchio (6 MCS). Several authors estimated that in Onna, settled in the Aterno river valley, ground motions were amplified at 2–3 Hz by up to a factor of 5 with respect to Monticchio, settled on more competent rocks. Although there was a general agreement that the spectral peak was caused by the resonance of the uppermost 40 m layer, a satisfactory fit of the amplitudes was not provided. Here, we apply spectral ratio techniques to 1437 aftershock seismograms (magnitude between 1.8 and 3.9) to compare ground motions within Onna and between Onna and Monticchio. Spectral amplitudes at stations located outside and inside the “red zone” of Onna show that the seismic response was uniform, confirming that vulnerability was crucial for the heavier damage of the ancient part of the village. We have also estimated the empirical transfer function of Onna through the spectral ratios between Onna and Monticchio. Although in a 1D simplification, a model with a further velocity contrast of ∼2 at 200 m of depth produces a more accurate fit of observations. Using the new velocity profile, we modeled the mainshock ground motion at Onna in an equivalent-linear approach. Accelerations are amplified by a factor of 2 and spectral ordinates increase from 0.7g at 0.2 s to 1g at 0.5 s, a shaking level that can be destructive for nonductile ancient buildings. This study shows that accurate estimates of empirical transfer functions, even in a simplified 1D approach, provide useful constraints to the deeper velocity structure where measurements are shallow or lacking.

Published: February 2020

Background: The fixed dose drug combinations (FDCs) of drugs is defined as product of two or more active ingredients in a defined composition. There is a need to study the pattern of prescription from time to time to evaluate their rationality. In this context we undertook this study to know the prescription pattern of FDC in our setting. To study the rationality of different prescribed FDCs.Methods: This is a prospective study which is carried out in NIMRA Institute of medical sciences which is a tertiary care teaching private hospital. For this study we have collected one thousand prescriptions of patients for 3 months that is from 10th March 2017 to 25th of June 2017 including both in-patients as well as outpatients. Selection criteria of patients mainly basing on their willingness to give prescriptions. Institutional ethical committee permission was taken for the study. The prescribed FDCs were compared with the essential drug list of FDCs approved by Drugs Controller General of India, July 2018. we have used descriptive statistics to analyze data. The percentage of FDCs used in each class and their contribution to overall FDCs were calculated.Results: In a total of 2952 drugs were prescribed, of this 747 were FDCs and 2205 were non FDCs. In the prescribed FDCs 89.2% drugs were rational and 10.8% drugs were irrational.Conclusions: From this study, we can conclude that 10.8% of irrational prescription of fixed dose drug combinations are prescribed in Nimra Institute of Medical Sciences which is a tertiary care teaching private hospital.

Background: Knee osteoarthritis is an important cause for morbidity in elderly people. Therapy is largely symptomatic with nonsteroidal anti-inflammatory drugs which pose risk in the elderly. Methionine is natural body constituent with novel property of blunting S-adenosylmethionine (SAMe) inflammatory process and cartilage degradation. The aim of this study was to compare effectiveness of SAMe, with standard etoricoxib therapy in newly diagnosed knee osteoarthritis cases.Methods: 127 newly diagnosed knee osteoarthritis patients were randomized into two groups. 55 participants received treatment of etoricoxib 600 mg extended release once daily for 90 days (group 1) and 72 received etoricoxib 600 mg extended release once daily and SAMe 400 mg twice daily for initial 15 days followed by SAMe once daily 400 mg as maintenance dose for next 75 days (group 2). The outcomes were measured by knee injury and osteoarthritis outcome score (KOOS). Pre and post treatment KOOS scores of all cases were separately pooled to define the median for whole as well as components of KOOS parameters. Relative frequencies of cases with values around respective medians were compared by MOODS median test. Patient characteristics, disease characteristics were also examined for bearing on outcomes besides the treatment.Results: SAMe treatment was associated with significantly greater improvement in symptoms, activities of daily life, spontaneous recreational activities and the quality of life compared to etoricoxib therapy. The therapy was well-tolerated.Conclusions: The study confirms SAMe as superior therapeutic option in osteoarthritis. SAMe indeed has been reported to have specific anti-arthritic effects and promotive to general well-being.
A study of clinical profile of intractable epilepsy in children
Authors: Sree C. Bhanu , Belavadi Gangadhar B. 
Published: February 2020

Background: This study was undertaken to find out the prevalence and clinical features of intractable epilepsy (IE) in a tertiary referral center.Methods: Study was conducted in a tertiary care hospital on 60 children with intractable epilepsy. Cases includes intractable epilepsy is when seizures continue to occur despite maximally tolerated doses of more than two antiepileptics, occurrence of an average of one seizure per month for 18 months with no more than a 3 month seizure free period during these 18 months. Controls: epileptic children who had good control of seizures for the previous 18 months.Results: The prevalence of intractable seizures was 10% with maximum number of children 25 (41.6%) belonged to the 5-12 years. 15 (50%) children had daily seizures. Myoclonic seizures proved to be an important predictor of intractability. 4 children among the cases had history of family seizures, 6 children in cases had history febrile seizure, whereas, 6 children among the controls had history of family seizures, 8 children in controls had history febrile seizure. 23.3% of children presented with Status epilepticus in the cases and 16.6% of the children in the controls. Remote symptomatic etiology 12(40%) is the commonest cause of seizure. 13 (43.3%) children in cases and 3 (10%) children among the controls had a history suggestive of birth asphyxia. EEG was abnormal in 17 (56.6%) cases when compared to 11 (36.6%) children in the controls. CT scan was abnormal in 14 (46.6%) cases and 10 (33.3%) controls. MRI was abnormal in 16 (53.3%) children of the cases and 8 (26.6%) children of the controls.Conclusions: The commonest cause of intractable epilepsy was perinatal asphyxia. Perinatal asphyxia can be prevented by good nutrition during pregnancy, regular antenatal check ups with detection of high risk pregnancy, promoting hospital deliveries and prompt resuscitation of newborn when required.
