Background
COVID-19 is an ongoing pandemic leading to exhaustion of the hospital care system. Our health care system has to deal with a high level of sick leave of health care workers (HCWs) with COVID-19 related complaints, in whom an infection with SARS-CoV-2 has to be ruled out before they can return back to work. The aim of the present study is to investigate if the recently described CoLab-algorithm can be used to exclude COVID-19 in a screening setting of HCWs.

Methods
In the period from January 2021 till March 2021, HCWs with COVID-19-related complaints were prospectively collected and included in this study. Next to the routinely performed SARS-CoV-2 RT-PCR, using a set of naso- and oropharyngeal swab samples, two blood tubes (one EDTA- and one heparin-tube) were drawn for analysing the 10 laboratory parameters required for running the CoLab-algorithm.

Results
In total, 726 HCWs with a complete CoLab-laboratory panel were included in this study. In this group, 684 HCWs were tested SARS-CoV-2 RT-PCR negative and 42 cases RT-PCR positive. ROC curve analysis showed an area under the curve (AUC) of 0.853 (95% CI: 0.801–0.904). At a safe cut-off value for excluding COVID-19 of -6.525, the sensitivity was 100% with a specificity of 34% (95% CI: 21 to 49%). No SARS-CoV-2 RT-PCR cases were missed with this cut-off and COVID-19 could be safely ruled out in more than one third of HCWs.

Conclusion
The CoLab-score is an easy and reliable algorithm that can be used for screening HCWs with COVID-19 related complaints. A major advantage of this approach is that the results of the score are available within 1 hour after collecting the samples. This results in a faster return to labour process of a large part of the COVID-19 negative HCWs (34%), next to a reduction in RT-PCR tests (reagents and labour costs) that can be saved.
Cetuximab-Induced Small Intestine Stricture in Metastatic Squamous Cell Carcinoma of the Oral Cavity
Authors: Eisa Mohamed , Omer Endashaw 
Published: June 2022

ABSTRACT
Cetuximab is an epidermal growth factor receptor (EGFR) inhibitor, which is used to treat patients with metastatic head and neck cancer. Dermatological reactions are the most serious adverse events associated with cetuximab treatment including an acne-like rash, xerosis, and pruritus. Other adverse effects include infections, hypomagnesemia, mucositis, conjunctivitis, nausea, and diarrhea. Mucositis is not only restricted to the oral mucosa, however, can affect any part of the gastrointestinal tract. The duration of treatment-related mucositis has been associated with stricture formation. We describe a case of chronic duodenal and jejunal strictures attributed to cetuximab use.
Fungus and Feathers: Combatting a Mold Outbreak in an Ornithological Collection
Authors: Trail Pepper W. , Woodward Ariel M. , French Johnnie H. 
Published: June 2022

Abstract
The ornithological collection of the National Fish and Wildlife Forensic Laboratory in Ashland, Oregon includes over 6,800 bird skin and loose feather specimens. These are essential reference material for the morphological identification of avian evidence in wildlife crime investigations by the U.S. Fish and Wildlife Service. In the summer of 2020, these specimens were moved from several locations and installed in a new building dedicated to the laboratory's bird, mammal, and herpetological collections. Following installation in the new building, a severe outbreak of mold was discovered in many of the cabinets containing bird specimens. This paper reports on the likely cause of the mold outbreak and the actions taken to control it, preserve the specimens, and prevent future outbreaks.
Fatal Autonomic Dysfunction Due to Guillain-Barré Syndrome After Cardiac Surgery
Authors: Selcuk Emre , Koksal Cengiz 
Published: June 2022

Guillain-Barré syndrome, a rare peripheral neuropathy, appears to occur more often in patients who have recently undergone surgery than in the general population. However, the pathophysiologic relationship between surgery and Guillain-Barré syndrome is elusive. Few cases of Guillain-Barré syndrome after cardiac surgery have been reported. Autonomic dysfunction, a serious complication of Guillain-Barré syndrome, has not been previously reported after cardiac surgery.
We describe the case of a 71-year-old woman in whom the acute motor axonal neuropathic subtype of Guillain-Barré syndrome developed after mitral valve replacement. Despite plasmapheresis and intravenous immunoglobulin therapy, she died of complications from severe autonomic dysfunction 25 days postoperatively. Recognizing the potential cardiovascular involvement of Guillain-Barré syndrome is important, because patients who undergo cardiac surgery can be vulnerable to autonomic dysfunction in the early postoperative period.

Intelligent terminal security technology of power grid sensing layer based upon information entropy data mining
Authors: Ren Shuai , Chen Defeng , Tao Yaodong , Xu Shuheng , Wang Gang , Yang Zhibin 
Published: June 2022

Abstract
The power grid is an important connection between power sources and users, responsible for supplying and distributing electric energy to users. Modern power grids are widely distributed and large in scale, and their security faces new problems and challenges. Information entropy theory is an objective weighting method that compares the information order of each evaluation index to judge the weight value. With the wide application of entropy theory in various disciplines, the subject of introducing entropy into the power system has been gradually concerned. This article aims to study the smart terminal security technology of the power grid perception layer based on information entropy data mining. This article analyzes its related methods and designs a smart terminal for the power grid. On this basis, a data analysis platform is built and a safety plan is designed. The result is that the average absolute error, root mean square error, average absolute percentage error, and mean square error of the platform's power load forecast are 1.58, 1.96, 8.2%, and 3.93, respectively. These error values are within the ideal range, and the data processing ability is strong. The packet loss rate of the adversary's eavesdropping was tested, and the average packet loss rates at locations a, b, c, and d were 1.05, 1.2, 1.81, and 2.2%, respectively. Data packets will be definitely lost, so the platform is highly secure.
Chirality-modulated photonic spin Hall effect in PT-symmetry
Authors: Liang Chengkang , Liu Dongxue , Liu Rao , Deng Dongmei , Wang Guanghui 
Published: June 2022

Abstract
The photonic spin Hall effect (PSHE), featured by a spin-dependent shift driven by its polarization handedness, is proposed to facilitate the applications in precision metrology and quantum information processing. Here, due to the magnetoelectric coupling of the chirality, the PSHE is accompanied with Goos–Hänchen and Imbert–Fedorov effects. Taking advantage of this superiority, the transverse shift (TS) and longitudinal shift (LS) can be applied simultaneously. Rearranging the PT-symmetric scattering matrix, the responsive PSHE near the exceptional points and their basic physical mechanisms are discussed in detail in the case of complex chirality κ. Re[κ] and Im[κ] regulated the rich (at multi-angle), gaint (reach upper limit) and tunable (magnitude and direction) TS and LS, respectively. Based on the chirality-modulated PSHE, the novel applications in binary code conversion and barcode encryption are proposed systematically. By incorporating the quantum weak measurement technology, our applications provide new mechanisms to realize optoelectronic communication.
The Effect of Children’s Exposure to the YouTube Platform Moshaya Family Channel on Socialization of the Saudi Child Regarding Life Satisfaction
Authors: Qutub Afnan A. , Muhammad Alaa A. 
Published: June 2022

Abstract
This study aims to measure the effects of exposure to a YouTube platform, the Moshaya Family Channel, on the socialization of children. We monitored the content provided by the channel and how children are affected by it in terms of moral and behavioral aspects, specifically the impacts of their repeated exposure to the programs on their life satisfaction. This needed to be studied due to the increase in views and subscriptions to the channel, and children’s level of attachment to the presented content. This research uses the survey method. An online questionnaire was used to obtain information from a study sample of 338 Saudi mothers whose children are watching “The Moshaya Family Channel.” Children’s ages ranged from 5 to 13 years old. The most important result is that a big proportion of children have the awareness of terms like subscribe, share, like and views. The reason for that is due to their being influenced by the idea of popularity and their desire to make their own YouTube channel. The research also found that a big proportion of children preferred prank content in the channel and described it as interesting, which pushed them to imitate these pranks in their lives. The research found that most mothers don’t like their children to watch the channel because it incites the child to prank others and prompts buying behavior in children. This confirms the role played by new media platforms, especially YouTube, which result in children acquiring values not only for entertainment, but also a tool for learning, communication and entertainment.
A semiotic analysis of images of Saudi Women’s rights in caricatures in light of Saudi Women’s empowerment
Authors: Al-Ghamdi Naimah Ahmed , Alqahtani Abeer , Alshahrani Lama , Elyas Tariq 
Published: June 2022

AbstractMany caricaturists get the idea for their caricature from current issues of society. The philosophy of the caricature lies in the opinion it presents, which discusses society’s goals, culture, and crises, and it is represented in an ironic way to deliver its visual message. The fight for women’s rights, inequality, and discrimination are examples of issues concerning Saudi women that have been represented by several caricaturists. Hence, the aim of this paper is to investigate female and male caricaturists’ linguistic and semiotic representation of Saudi women’s challenging issues. Following (Kress and Van Leeuwen. 2006.Reading images: The grammar of visual design, 2nd edn. London: Routledge), a social semiotic multimodal approach to the analysis is adopted in this study, which is drawn from Halliday’s social semiotic theory. Twenty caricatures were carefully selected based on the content and the issues that are being discussed in the caricatures with a consideration of their relation to the aim of the study. The present study contributes to enriching Saudi women’s rights in relation to Saudi Vision 2030. The research is significant in that, in examining women/male caricaturists’ representations of the challenges and opportunities of Saudi women empowerment prior/after Saudi Vision 2030 in the workplace, social life, it contributes to understanding the supportive caricature discourse, basic social values for Saudi women, the pressures they undergo, and the success they have achieved so far in attaining their rights. The study findings show that both the semiotic and verbal elements of the caricatures were significant in delivering the messages for women’s rights in the new Saudi.
Electromechanical properties of housed piezoelectric CTGS resonators at high temperatures – Modeling of housing influence
Authors: Schulz Michal , Ghanavati Rezvan , Kohler Fabian , Wilde Jürgen , Fritze Holger 
Published: June 2022

Abstract
The use of piezoelectric sensors in harsh environments requires their protection by housing. Therefore, it is essential to select materials used for the housing carefully. They should not only withstand the same conditions as the active element while providing protection for it, but also influence the piezoelectric component as little as possible. Mechanical stress or electric short-cut of the signals must be avoided as it leads to strong damping and to reduction of e. g. mass or temperature resolution. Therefore, understanding of housing impact on the piezoelectric sensor plays an important role in research and development.
Housed as well as unhoused CTGS resonators are analyzed at temperatures up to 1000 °C. The electrical impedance in the vicinity of the resonance frequency is acquired and modeled by electric equivalent circuits that are fitted to the data. The circuit models describing unhoused and housed CTGS resonators are an extension of the Butterworth-van Dyke equivalent circuit. Analysis of the data reveals that the realized housing impacts the behavior of the CTGS resonators only slightly above ca. 600 °C, whereas this influence is negligible for typical applications.
