Resonator-free tunable sub-MHz spectral dip in the Brillouin gain using spun birefringent fibers
Authors: Choksi Neel , Liu Yi , Ghasemi Rojina , Qian Li 
Published: April 2021

Abstract
Ultra-narrow spectral features are desirable for a broad range of applications, and they are conventionally realized using ultrahigh Q resonant structures. These structures typically require precision fabrication processes, and moreover, since they are passive, they suffer from signal loss. Here, we demonstrate a novel way to achieve sub-MHz tunable spectral dip in the Brillouin gain spectrum of a spun birefringent fiber (SBF) without loss, and without using a resonator. We show that this dip is unique to SBF, where its polarization eigenmodes are elliptical and frequency-dependent, and the dip only occurs when these orthogonal polarization eigenmodes of the SBF (at the respective pump and signal frequencies) are launched in counter-propagating directions. We experimentally demonstrate a 0.72 MHz spectral dip in the Brillouin gain spectrum of a commercial SBF which is to our knowledge, the narrowest SBS spectral feature ever reported. Furthermore, the linewidth, depth, and spectral location of this dip are tunable on demand by controlling the pump frequency, pump power, and the input polarization of the signal. Its simplicity in implementation, its ultra-narrow linewidth, and its tunability can have a wide range of potential applications, from slow-light to microwave photonics.
How to really help bees: nutrient demand and supply in a changing environment
Authors: Filipiak Zuzanna , Denisow Bozena , Stawiarz Ernest , Filipiak Michał 
Published: April 2021

Abstract
Local and global changes affect which pollen varieties are available to bees in the environment. Therefore, wild bees cannot always access the optimally balanced diet required for their survival. Our feeding experiment showed that the nutritional quality of the pollen diet eaten by bee larvae is shaped not by pollen diversity but by a specific pollen species composition that results in specific nutrients being scarce or sufficient; this species composition influences bee survivability, development and mass. We proposed that the functioning of bee populations and communities may depend on the floral diversity of the local habitat, which determines whether a nutritionally balanced pollen diet obtained from specific species can be provided to bee larvae. Holistically considering wild bee fitness and health and the different characteristics of the food base at both the ecosystem and bee biology levels can provide new, important knowledge for conserving bees and their critical ecological roles.

Abstract
Purpose: This paper is intended to report the ultrastructural and biological features of VisionGraft®, a commercially available acellular gamma-irradiated sterile cornea. This is the first known ultrastructural examination of the VisionGraft® with electron microscopy after in-vivo explanation. Observations: This graft was initially placed for tectonic purposes in a non-responsive culture positive Aspergillus keratitis in a 50 year-old diabetic male, unresponsive to maximal medical therapy. Five months later, a second penetrating keratoplasty with fresh tissue was performed and the Visiongraft® was submitted for histopathologic evaluation. This study reports that there is minimal regrowth of nerves and endothelial cells into the graft, and corneal clarity appears to be preserved even in the absence of endothelium. Conclusions and Importance: Examination of the acellular cornea showed no significant epithelial regrowth, no nerve regeneration, no infiltration by leukocytes or antigen presenting cells, no significant endothelial regrowth, and yet, surprisingly, no interstitial edema. We offer some hypotheses for these observations based on the histopathologic evaluation and offer some suggestions for future avenues of research.
Deep learning in geodesy
Authors: Sorkhabi Omid Memarian 
Published: April 2021

Abstract
Deep learning (DL) can be a way to automate the analysis of predictions. DL algorithms are in the hierarchy of increasing complexity and abstraction while traditional machine learning is linear. In this study, the downscaling of the GRACE-FO satellite was investigated using a convolutional neural network (CNN). Three solutions were used for downscaling with CNN. Down-scaling accuracy is estimated to be 0.1 degree and its absolute error is 1 mm. The results show that this method can improve the GRACE-FO spatial resolution problem with higher efficiency and make it easier to analyze the results. Also, DL can solve many geodesy problems.
Unconventional reconciliation path for quantum mechanics and general relativity
Authors: Yuguru Samuel 
Published: April 2021

Abstract
Physics in general is successfully governed by quantum mechanics at the microscale and principles of relativity at the macroscale. Any attempts to unify them using conventional methods have somewhat remained elusive for nearly a century up to the present stage. Here in this study, a classical gedanken experiment of electron-wave diffraction of a single slit is intuitively examined for its quantized states. A unidirectional monopole field as quanta of the electric field is pictorially conceptualized. Its application towards quantum mechanics and general relativity in accordance with existing knowledge in physics paves an alternative path towards their reconciliation process. This assumes a multiverse at a hierarchy of scales with gravity localized to a body into space. Such an outcome provides an approximate intuitive guide to examine physics in general from alternative perspectives using conventional methods.

Published: April 2021

Modern paradigm of society digitalization, based on the introduction of digital economy and management, on new information and computer technologies is considered. The example of the European Union and Morocco in the context of cross-cultural analysis shows how to form a similar paradigm in order to bring the country to the level of an advanced one. At the heart of the digital economy and digital management is the introduction of innovations in various sectors of national economy. The European Union has focused on four key areas: 1) skills; 2) infrastructure; 3) public services; 4) digitalization of business, which contributes to the digital revolution. By increasing their capacity, countries have been able to steer the digital transformation of the world for the better by expanding international technological cooperation. At the same time, three main principles should be followed: 1) equal“playing field” in digital markets; 2) security in cyberspace; 3) freedom online. The example of Morocco as a developing country shows that the country has chosen a scenario for the development of digital technologies and this logic has led to the current development of modern ICT and to the absence of a gap in the mentioned sector. In order to remain competitive in 10 years (as Morocco does), it is necessary to begin digital transformation today and change must affect not only the IT system, but also the people and leaders, their consciousness and culture, the formation of algorithmic thinking in the organization, for which the state should regulate this sector and develop the infrastructure of organizations and advanced innovative thinking.
Rare Pulmonary Tumors and Carcinoma Mimickers; Experience from an Interventional Radiology Unit with Radiologic-pathologic Correlation- A Pictoral Essay
Authors: Ünal Emre , Arslan Sevtap , Aghayeva Gulnar , Sarıkaya Yasin , Çifti Türkmen , Önder Sevgen , Akıncı Devrim , Akhan Okan 
Published: April 2021

Background:
Although imaging findings along with patients’ clinical history may give
a clue for the etiology of a pulmonary lesion, the differentiation of benign pulmonary lesions from
lung cancer could be challenging.

Objective:
The aim of this review article was to increase the awareness of carcinoma mimicking
lung lesions.

Methods:
This paper was designed to illustrate rare pulmonary tumors and carcinoma mimickers
with emphasis on radiologic-pathologic correlation. Pitfalls encountered on CT images and also
false positivity of PET-CT scans were also presented.

Conclusion:
Several benign pulmonary lesions may grow in size on follow-up and some may
show pathologic FDG (18F-fluorodeoxyglucose) uptake, which makes them indistinguishable from
lung carcinoma by imaging. In addition, some slow-growing malignant lesions, such as carcinoid,
may be false-negative on PET/CT scans.
Effect of Visual Cognition on the Measurement of Particle Size Using ImageJ Software
Authors: Debut Alexis , Vizuete Karla , Pazmiño Katherine , Calderón Janyna , Gallegos Camila , Gaona Vanessa 
Published: April 2021

Background:
Nanoparticles are structures up to 100 nm in size. Estimation of their
size is usually determined by assessing of images obtained from scanning electron microscopy
(SEM) and/or transmission electron microscopy (TEM) techniques. Studies on the effect of visual
cognition on the analysis of these types of images are limited.

Objective:
The aim of the research was to determine whether students’ visual cognition influences
the identification, analysis, and measurement of nanoparticle size through SEM and TEM
imaging using ImageJ software.

Methods:
The visual cognition of each participant was evaluated by recognizing individual nanoparticles
and measuring their diameter using ImageJ software. Finally, the Kruskal Wallis test
was performed for statistical analysis.

Results:
Participants applied or not four main identification criteria in order to identify individual
nanoparticles: shape, high contrast, defined edges, and presence/absence of agglomerates,
being “shape” the predominant parameter taken into account to measure the diameter using ImageJ.
Average diameters, number of measured nanoparticles, and standard errors of measurements
varied between groups in all analyzed images, evidencing the influence of visual cognition
on the measurements.

Conclusion:
We conclude that there is an effect of visual cognition in the identification of nanoparticles
and their diameter estimation. The user’s training, background, experience, perspective,
and operational conditions of SEM/TEM play a fundamental role in estimating the size of
nanoparticles measured in microphotographs using ImageJ.
Shared Decision-Making With a Virtual Patient in Medical Education: Mixed Methods Evaluation Study
Authors: Jacklin Simon , Maskrey Neal , Chapman Stephen 
Published: April 2021

Background
Shared decision-making (SDM) is a process in which clinicians and patients work together to select tests, treatments, management, or support packages based on clinical evidence and the patient’s informed preferences. Similar to any skill, SDM requires practice to improve. Virtual patients (VPs) are simulations that allow one to practice a variety of clinical skills, including communication. VPs can be used to help professionals and students practice communication skills required to engage in SDM; however, this specific focus has not received much attention within the literature. A multiple-choice VP was developed to allow students the opportunity to practice SDM. To interact with the VP, users chose what they wanted to say to the VP by choosing from multiple predefined options, rather than typing in what they wanted to say.

Objective
This study aims to evaluate a VP workshop for medical students aimed at developing the communication skills required for SDM.

Methods
Preintervention and postintervention questionnaires were administered, followed by semistructured interviews. The questionnaires provided cohort-level data on the participants’ views of the VP and helped to inform the interview guide; the interviews were used to explore some of the data from the questionnaire in more depth, including the participants’ experience of using the VP.

Results
The interviews and questionnaires suggested that the VP was enjoyable and easy to use. When the participants were asked to rank their priorities in both pre- and post-VP consultations, there was a change in the rank position of respecting patient choices, with the median rank changing from second to first. Owing to the small sample size, this was not analyzed for statistical significance. The VP allowed the participants to explore a consultation in a way that they could not with simulated or real patients, which may be part of the reason that the VP was suggested as a useful intervention for bridging from the early, theory-focused years of the curriculum to the more patient-focused ones later.

Conclusions
The VP was well accepted by the participants. The multiple-choice system of interaction was reported to be both useful and restrictive. Future work should look at further developing the mode of interaction and explore whether the VP results in any changes in observed behavior or practice.
Social Media Content of Idiopathic Pulmonary Fibrosis Groups and Pages on Facebook: Cross-sectional Analysis
Authors: Kochan Andrew , Ong Shaun , Guler Sabina , Johannson Kerri A , Ryerson Christopher J , Goobie Gillian C 
Published: April 2021

Background
Patients use Facebook as a resource for medical information. We analyzed posts on idiopathic pulmonary fibrosis (IPF)-related Facebook groups and pages for the presence of guideline content, user engagement, and usefulness.

Objective
The objective of this study was to describe and analyze posts from Facebook groups and pages that primarily focus on IPF-related content.

Methods
Cross-sectional analysis was performed on a single date, identifying Facebook groups and pages resulting from separately searching “IPF” and “idiopathic pulmonary fibrosis.” For inclusion, groups and pages needed to meet either search term and be in English, publicly available, and relevant to IPF. Every 10th post was assessed for general characteristics, source, focus, and user engagement metrics. Posts were analyzed for presence of IPF guideline content, useful scientific information (eg, scientific publications), useful support information (eg, information about support groups), and potentially harmful information.

Results
Eligibility criteria were met by 12 groups and 27 pages, leading to analysis of 523 posts. Of these, 42% contained guideline content, 24% provided useful support, 20% provided useful scientific information, and 5% contained potentially harmful information. The most common post source was nonmedical users (85%). Posts most frequently focused on IPF-related news (29%). Posts containing any guideline content had fewer likes or comments and a higher likelihood of containing potentially harmful content. Posts containing useful supportive information had more likes, shares, and comments.

Conclusions
Facebook contains useful information about IPF, but posts with misinformation and less guideline content have higher user engagement, making them more visible. Identifying ways to help patients with IPF discriminate between useful and harmful information on Facebook and other social media platforms is an important task for health care professionals.
