AbstractWith increasing global interest in molecular hydrogen to replace fossil fuels, more attention is being paid to potential leakages of hydrogen into the atmosphere and its environmental consequences. Hydrogen is not directly a greenhouse gas, but its chemical reactions change the abundances of the greenhouse gases methane, ozone, and stratospheric water vapor, as well as aerosols. Here, we use a model ensemble of five global atmospheric chemistry models to estimate the 100-year time-horizon Global Warming Potential (GWP100) of hydrogen. We estimate a hydrogen GWP100 of 11.6 ± 2.8 (one standard deviation). The uncertainty range covers soil uptake, photochemical production of hydrogen, the lifetimes of hydrogen and methane, and the hydroxyl radical feedback on methane and hydrogen. The hydrogen-induced changes are robust across the different models. It will be important to keep hydrogen leakages at a minimum to accomplish the benefits of switching to a hydrogen economy.

Authors: Power-deFur Lissa A. 
Published: June 2023

Purpose:This review of federal statutes, regulations, administrative directions, and case law related to special education, disabilities, and school nutrition is designed to provide speech-language pathologists (SLPs) with information essential for determining eligibility children with pediatric feeding disorder (PFD). Despite the absence of mention of dysphagia or PFD in federal statutes and regulations, special education, disability, and school food service requirements provide direction for serving children with health care needs, which include children with dysphagia. The federal requirements, court cases, and policy interpretations are detailed to provide guidance to SLPs and their school teams when working with children with PFDs.Method:Federal statutes and regulations, administrative directions, and case law were reviewed. This review details the application of federal statutes and regulations for children with PFDs. Furthermore, administrative direction and case law identify the importance of attending to the safety of children with dysphagia.Results:As a result of this review, sections of the various federal statutes and regulations that support provision of services to children with PFD are identified. In addition, information from case law and administrative reviews further highlights the importance of attending to the rights and needs of children with PFD.Conclusions:The rights of all children with disabilities are established through statutes, regulations, and case law, and children with PFDs benefit from these rights. These requirements can guide SLPs in working with school teams, so that children with dysphagia can be found eligible for and receive school-based services for dysphagia.

Published: June 2023

Purpose:
Speech-language pathologists (SLPs) are tasked with integrating the principles of evidence-based practice (EBP) to provide effective and efficient assessment and intervention services that best support clients and their families. As new research, technologies, and perspectives emerge, SLPs are required to adapt their clinical practices to meet these changes while maintaining high-quality evidence-based services. Through an illustrative case study, we aim to demonstrate the process of applying EBP principles—including research evidence, client and family perspectives, and clinical expertise—to a complexity-based speech sound intervention delivered via telepractice.

Conclusions:
Results of the case study suggest that utilizing the principles of EBP to transition an evidence-based complexity intervention to telepractice was successful. Additionally, the EBP framework provided opportunities for reflection and continued adaptation throughout the intervention. The process of applying an EBP framework to a quickly evolving clinical practice environment provides SLPs with essential tools that ensure their services meet the needs of the clients they serve.

ZusammenfassungKrebspatienten erkranken häufiger und schwerer an einer
SARS-CoV-2-Infektion. Schwarzkümmel und seine Leitsubstanz Thymochinon
wirken u.a. antiviral. Der Wirkungsmechanismus der antiviralen Wirkung gegen
SARS-CoV-2 ist weitgehend aufgeklärt. Beide stimulieren und modulieren
darüber hinaus auch die humorale und zelluläre Immunantwort. Die
Signalwege der COVID-19-Komplikationen werden gehemmt und so wird einer
pulmonalen Hypertonie und Lungenfibrose sowie einem Lungenödem und
akutem Lungenversagen vorgebeugt.Fünf explorative Studien weisen auf eine Wirksamkeit bei der
COVID-19-Erkrankung hin. Die im Internet veröffentlichte Meta-Analyse
mit 10 Studien ist von inakzeptabler Qualität und erlaubt keine Angabe
zur Wirkgröße des Schwarzkümmels. Konfirmatorische
Studien müssen die Ergebnisse zur Wirksamkeit
überprüfen. Es wird vermutet, dass mit einer optimalen
Kombination verschiedener Pflanzenwirkstoffe die effektivste
Behandlungsstrategie gegen eine SARS-CoV-2-Infektion erzielt werden kann.Eine Tagesdosis mit bis zu 50 mg Thymochinon kann ohne
Sicherheitsbedenken oral eingenommen werden. Eigene Untersuchungen zeigen, dass
kommerzielle Schwarzkümmelpräparate nur wenig Thymochinon
enthalten. Ein wirkstoffkontrolliertes Präparat ist Voraussetzung
für eine erfolgreiche Behandlung.

Concise Total Synthesis of Complanadine A Enabled by Pyrrole-to-Pyridine Molecular Editing

Published: June 2023

AbstractThe Lycopodium alkaloid complanadine A, isolated in 2000, is a complex and unsymmetrical dimer of lycodine. Biologically, it is a novel and promising lead compound for the development of new treatments for neurodegenerative disorders and persistent pain management. Herein, we report a concise synthesis of complanadine A using a pyrrole-to-pyridine molecular editing strategy. The use of a nucleophilic pyrrole as the precursor of the desired pyridine enabled an efficient and one-pot construction of the tetracyclic core skeleton of complanadine A and lycodine. The pyrrole group was converted into a 3-chloropyridine via Ciamician–Dennstedt one-carbon ring expansion. A subsequent C–H arylation between the 3-chloropyridine and a pyridine N-oxide formed the unsymmetrical dimer, which was then advanced to complanadine A. Overall, from a readily available known compound, the total synthesis of complanadine A was achieved in 11 steps. The pyrrole-to-pyridine molecular editing strategy enabled us to significantly enhance the overall synthetic efficiency. Additionally, as demonstrated by Suzuki–Miyaura cross-coupling, the 3-chloropyridine product from the Ciamician–Dennstedt rearrangement is amenable for further derivatization, offering an opportunity for simplified analogue synthesis.
p-TSA·H2O-Catalyzed Synthesis of 2,3-Diarylquinoline Derivatives via One-Pot Three-Component Reaction
Authors: Khan Abu Taleb , Faraz Simra 
Published: June 2023

AbstractAn environmentally benign synthesis of 2,3-diarylquinolines is reported via a one-pot three-component reaction from arylamines, benzaldehyde, and styrene oxide in the presence of 20 mol% p-TSA·H2O at 120 °C. This protocol does not require metal catalysts, additives, and extra oxidants. Mechanistic studies confirm the crucial role of p-TSA·H2O and the use of air as the sole oxidant makes this transformation very attractive. The salient feature of this protocol is easy handling, broad substrates scope, shorter reaction time, high atom economy, regioselectivity, and good yields; and the formation of one C–N and two C–C bonds takes place in a single step.
A Case of Malignant Melanotic Schwannoma of the Trigeminal Nerve: A Case Report and Review of Literature
Authors: Dandekar Anurag Chandrakant , Mehta Nirav A. 
Published: June 2023

AbstractIntracranial melanotic schwannoma is quite rare, and involvement of the trigeminal nerve is even rarer. Early diagnosis and surgical excision are the mainstays of management. These tumors have a high tendency to recur and there is high possibility of metastasis. Adjuvant radiotherapy should be considered since the prognosis is uncertain. A 23-year-old man started developing numbness over the left side of the forehead 9 months ago that progressed to involve the ipsilateral cheek. The patient started having diplopia on looking to the left side 8 months ago. His relatives noticed a change in his voice 1 month ago and he developed weakness in the right upper and lower limbs, which was gradually progressive. The patient had slight difficulty swallowing. After examination, we found involvement of multiple cranial nerves with pyramidal signs. Magnetic resonance imaging (MRI) was suggestive of an extra-axial lesion in the left cerebellopontine angle extending into the middle cranial fossa, which was having high T1 and T2 signal loss with contrast enhancement. We achieved near-total excision of the tumor via a subtemporal extradural approach. Trigeminal melanotic schwannoma is a rare occurrence constituting melanin-producing cells and Schwann cells. Rapid progression of symptoms and signs should prompt the suspicion of the possible malignant nature of the pathology. Extradural skull base approaches reduce the risk of postoperative deficits. Differentiating melanotic schwannoma from malignant melanoma is of utmost importance in planning of management.
Isolated Cerebral Cyst Hydatid Removal with Dowling's Technique in a 6-Year-Old Pediatric Patient: Case Report

Published: June 2023

AbstractHydatid disease, caused by the Echinococcus parasite, is a worldwide zoonosis produced by the larval stage of the tapeworm. In urban living patients with cerebral abscesses, hydatid cysts should not be excluded from the differential diagnosis. We report an exceptional primary cerebral hydatid cyst in which imaging showed a large, round, contrast-enhancing lesion with a mass effect. The patient presented with a dull headache for over a year and progressively worsened left hemiparesis. The magnetic resonance imaging showed a huge intracranial mass, and the pathology was corrected with cyst hydatid. Surgery was performed via Dowling's technique, and the patient recovered without neurologic deficits. Echinococcosis should be considered a differential diagnosis for single or multiple cerebral abscesses, even in the absence of liver infections. The history of living in rural areas does not exclude cerebral hydatid cysts and Echinococcus.
Ipsilateral Visual Loss Caused by Optic Nerve Compression between a Tuberculum Sellae Meningioma and the Internal Carotid Artery

Published: June 2023

AbstractWe report a rare case of ipsilateral visual loss caused by compression of the optic nerve between a tuberculum sellae meningioma (TSM) and the internal carotid artery (ICA). The patient was a 70-year-old female who presented with a 2-year history of left visual disturbance with a TSM on magnetic resonance imaging. No tumor infiltration to the optic canal was identified in the preoperative images. Extended endoscopic transsphenoidal surgery was performed and showed no infiltration to the optic canal. The tumor was removed completely, and optic nerve compression was found between the TSM and atherosclerotic ICA. This report shows an atypical case in which compression of the optic nerve between a TSM and the ICA caused ipsilateral visual loss despite no infiltration to the optic canal.

Published: June 2023

Abstract
Purpose Reconstruction and stabilization of ulnar stump after distal ulna tumor resection is still a matter of debate. We present the outcomes of ulnar buttress arthroplasty without stabilization of the ulna stump in giant cell tumor of bone (GCTB) of the distal ulna.
Methods Evaluation of functional outcome was performed using Musculoskeletal Tumor Society 93 (MSTS93) score, Modified Mayo Wrist score (MMWS), and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. We also assessed the hand grip strength, range of motion at the wrist, and ulnar carpal translation.
Results The study included 8 patients with Campanacci grade 3 GCTB of the distal ulna with a mean follow-up of 35.5 ± 9.1 months. The mean resection length was 7.7 ± 1.3 cm. The mean hand grip strength on the operated side was noted to be 90 ± 0.04% of the contralateral side. Mean MSTS93 score was 27.9 ± 1.25, mean MMWS was 86.9 ± 4.58%, and the mean DASH score was 4.9 ± 1.67, depicting a good to excellent functional outcome with low degree of disability. No radiocarpal instability, ulnar carpal translation, prominence, or instability of the proximal ulnar stump was noted in any patient.
Conclusion Reconstruction of the distal radioulnar joint using iliac crest bone graft for ulnar buttress without stabilization of the ulnar stump after resection of the distal ulna is an effective reconstruction option with good functional outcome and preservation of good hand grip strength.

Neutrons generated in Inertial Confinement Fusion (ICF) experiments provide valuable information to interpret the conditions reached in the plasma. The neutron time-of-flight (nToF) technique is well suited for measuring the neutron energy spectrum due to the short time (100 ps) over which neutrons are typically emitted in ICF experiments. By locating detectors 10s of meters from the source, the neutron energy spectrum can be measured to high precision. We present a contextual review of the current state of the art in nToF detectors at ICF facilities in the United States, outlining the physics that can be measured, the detector technologies currently deployed and analysis techniques used.

Today, the use of wind energy by wind turbines has grown significantly, and this development is due to the production of required energy and tourism attraction of wind turbines. But according to the standard technologies used in this industry, the operating costs are very high. For this reason, before the construction of wind farms, potential measurements should be done along with economic analysis. Therefore, in this research, a statistical analysis of wind farms has been done. In the statistical analysis, Weibull and Rayleigh distribution functions were used to predict the wind speed of the studied area. MATLAB software is used to model prediction functions. Among the important results of wind speed prediction by the Weibull distribution function, it can be mentioned that the wind speed is variable between 0.6 and 7 m/s in the studied area. The total power density and wind energy in the 10 years are equivalent to 28 W/m2 and 810/0534 kWh/m2 at the height of 10 m calculated.
A comparative study of superconductivity at LaAlO3/SrTiO3 and BaTiO3/LaAlO3/SrTiO3 heterointerfaces
Authors: Yan Qiaohong , Gao Haobin , Peng Wei , Zhu Xiaohong 
Published: June 2023

Lead-free BaTiO3 (BTO) film was fabricated by pulsed laser deposition on LaAlO3/SrTiO3 (LAO/STO) heterostructure in oxygen pressure of 2 × 10−3 Pa, which is experimentally required for ensuring the two-dimensional electron gas at LAO/STO heterointerface. Modulation of back-gate voltage on the superconductivity of LAO/STO and BTO/LAO/STO heterointerfaces was studied. The results indicate that the back-gate voltage can adjust the resistance at high temperatures around 300 mK, while it does not modulate the superconducting transition temperature of LAO/STO, which occurs at 160 mK. As for BTO/LAO/STO, it still shows a superconducting transition-like behavior at 110 mK. However, when a negative back-gate voltage is applied, the superconducting transition-like behavior disappears, and after removing the voltage, unlike what was observed for LAO/STO, the superconductivity cannot be recovered. Given this, some underlying mechanisms are proposed.
New topological rainbow trapping approach for phononic beam-foundation systems

Published: June 2023

Abstract
Rainbow trapping is of great significance for frequency-based wave splitting and broadband wave attenuation. By recognizing the deficiency of prevailing gradient rainbow reflection devices in terms of energy concentration and broadband vibration isolation, we design a new topological rainbow trapping device by introducing a topological protected interface mode (TPIM) into the prevailing gradient rainbow device. Therefore, a topological rainbow trapping beam composed of a homogenous beam rested on an alternate and gradient foundation is constructed. Using theoretical and numerical analysis, we perform a unit-cell band structure analysis. The dependence of bandgap region and group velocity on the reference foundation stiffness is investigated. With the help of the topological phase transition and Zak phase analysis, we successfully predict and demonstrate TPIM. A quantitative evaluation of the advancement of topological rainbow devices upon the prevailing gradient device in vibration amplification and broadband wave attenuation is also presented. We believe that the robust one-dimensional topological rainbow trapping beam will be useful in many applications, such as energy harvesting, wave splitting, and vibration control.

Abstract
In this work, we investigate the intrinsic as well as modulated optical properties of the AB-stacking bilayer armchair graphene ribbons in the absence and presence of external electric fields. Single-layer ribbons are also considered for comparison. By using a tight-binding model in combination with the gradient approximation, we examine the energy bands, the density of states and the absorption spectra of the studied structures. Our results demonstrate that when external fields are not present, the low-frequency optical absorption spectra display numerous peaks and they vanish at the zero point. In addition, the number, the position, and the intensity of the absorption peaks are strongly associated with the ribbon width. With the wider ribbon width, more absorption peaks are present and a lower threshold absorption frequency is observed. Interestingly, in the presence of electric fields, bilayer armchair ribbons exhibit a lower threshold absorption frequency, more absorption peaks, and weaker spectral intensity. When increasing the strength of the electric field, the prominent peaks of the edge-dependent selection rules are lowered, and the sub-peaks satisfying the extra selection rules come to exist. The obtained results certainly provide a more comprehensive understanding of the correlation between the energy band transition and the optical absorption, in both single-layer and bilayer graphene armchair ribbons, and could provide new insights into developments of optoelectronic device applications based on graphene bilayer ribbons.
On the 1-prevalent continuous functions on compact sets and dimensions

The main goal of this paper is to consider the generic properties of continuous functions in C(K) in terms of upper box dimension and packing dimension in the sense of prevalence. Precisely, we show that, the function
