Hawkmoths regulate flight torques with their abdomen for yaw control
Authors: Le Viet , Cellini Benjamin , Schilder Rudolf , Mongeau Jean-Michel 
Published: March 2023

ABSTRACT
Many animals use body parts such as tails to stabilize posture while moving at high speed. In flying insects, leg or abdominal inertia can influence flight posture. In the hawkmoth Manduca sexta, the abdomen contributes ∼50% of the total body weight and it can therefore serve to inertially redirect flight forces. How do torques generated by the wings and abdomen interact for flight control? We studied the yaw optomotor response of M. sexta by using a torque sensor attached to their thorax. In response to yaw visual motion, the abdomen moved antiphase with the stimulus, head and total torque. By studying moths with ablated wings and a fixed abdomen, we resolved abdomen and wing torques and revealed their individual contribution to total yaw torque production. Frequency-domain analysis revealed that the abdomen torque is overall smaller than wing torque, although the abdomen torque is ∼80% of the wing torque at higher visual stimulus temporal frequency. Experimental data and modeling revealed that the wing and abdomen torque are transmitted linearly to the thorax. By modeling the thorax and abdomen as a two-link system, we show that abdomen flexion can inertially redirect the thorax to add constructively to wing steering efforts. Our work argues for considering the role of the abdomen in tethered insect flight experiments that use force/torque sensors. Taken together, the hawkmoth abdomen can regulate wing torques in free flight, which could modulate flight trajectories and increase maneuverability.
Nowe stanowiska Evernia divaricata (L.) Ach. w zachodniej Polsce

Published: March 2023

A new locality of a rare fruticose lichen species Evernia divaricata in the western part of Poland was found in the vicinity of two cities: Gubin and Twardogóra. Single specimens of this epiphytic lichen, grew on larch and birch. The thalli were healthy and well developed. Evernia divaricata is under strict legal protection and considered an endangered species in Poland (the CR category in the „Red List of Polish Lichens”). In the last dozen or so years, over a dozen new localities of E. divaricata have been found in the country, which usually grew in the company of other lichens very sensitive to air pollution, e.g. from the genus Usnea. These taxa are a testimony to the increasing process of recolonization.
RSOME in Python: An Open-Source Package for Robust Stochastic Optimization Made Easy
Authors: Chen Zhi , Xiong Peng 
Published: March 2023

We introduce a Python package called RSOME for modeling a wide spectrum of robust and distributionally robust optimization problems. RSOME serves as an open-source framework for modeling various optimization problems subject to distributional ambiguity in a highly readable and mathematically intuitive manner. It is versatile and fits well in the open-source software community in the sense that (i) it is consistent with NumPy arrays in indexing and slicing and; (ii) together with the rich Python libraries for machine learning, data analysis, and visualization, it is easy to implement data-driven models; and (iii) it provides convenient interfaces for users to switch and tune parameters among different solvers.

COPD: what GPNs need to know from the latest GOLD update
Authors: Bostock Beverley 
Published: March 2023

Every year, the Global Initiative for Obstructive Lung Disease publishes its update on COPD. Beverley Bostock provides an overview of what the latest publication means for general practice nurses The latest guidance from the Global Initiative for Obstructive Lung Disease (GOLD) on chronic obstructive pulmonary disease (COPD) will have an impact on the management of patients in general practice. The definition of COPD has been updated as well as the recommended approach to diagnosis. Updated treatment recommendations act as an important reminder for primary care clinicians to implement interventions that are relevant in the community setting and to refer on for more specialised interventions in secondary care as appropriate. The replacement of the ABCD assessment tool with the ABE approach underlines the significant impact that exacerbations can have in the management of COPD, independent of the symptom burden. Updated sections on exacerbations remind clinicians of the importance of considering comorbid or new diagnoses as the cause of any symptoms.
Applicants to a Special Education Advocacy Training Program: “Insiders” in the Disability Advocacy World
Authors: Goscicki Brittney L. , Goldman Samantha E. , Burke Meghan M. , Hodapp Robert M. 
Published: March 2023

Abstract
Although social groups have “insiders,” this construct has not been measured within the disability advocacy community. Examining 405 individuals who applied for an advocacy training program, this study examined the nature of insiderness within the disability advocacy community and ties to individual roles. Participants showed differences in mean ratings across 10 insider items. A principal components analysis revealed two distinct factors: Organizational Involvement and Social Connectedness. Non-school providers scored highest on Organizational Involvement; family members/self-advocates highest on Social Connectedness. Themes from open-ended responses supported the factors and showed differences in motivation and information sources across insiderness levels and roles. Qualitative analysis revealed two additional aspects of insiderness not addressed in the scale. Implications are discussed for future practice and research.
A Tale of Two Adaptations of a Special Education Advocacy Program
Authors: Burke Meghan M. , Goldman Samantha E. , Li Chak 
Published: March 2023

Abstract
Special education advocacy programs support families to secure services for their children with intellectual and developmental disabilities. Although research demonstrates the efficacy of one such program (the Volunteer Advocacy Project), its effectiveness when replicated by others is unknown. Replication research is critical to ensure that programs can remain effective. The purpose of this study was to explore the adaptation process for two agencies that replicated an advocacy program. Quantitative and qualitative data were collected to examine feasibility, acceptability, and effectiveness. Although it took resources to replicate the advocacy program, agencies reported ongoing implementation would be easier once adaptations were completed. The adapted programs were effective in increasing participants' knowledge, empowerment, advocacy, and insiderness. Implications for research and practice are discussed.
Chronic cough in post-COVID syndrome: Laryngeal electromyography findings in vagus nerve neuropathy
Authors: García-Vicente Patricia , Rodríguez-Valiente Antonio , Górriz Gil Carmen , Márquez Altemir Reyes , Martínez-Pérez Francisco , López-Pajaro Luis Fernando , García-Berrocal Jose Ramón 
Published: March 2023

Background
Despite being a new entity, there is a large amount of information on the characteristics of SARS-CoV-2 infection and the symptoms of the acute phase; however, there are still many unknowns about the clinical features and pathophysiology of post-COVID syndrome. Refractory chronic cough is one of the most prevalent symptoms and carries both a medical problem and a social stigma. Many recent studies have highlighted the role of SARS-CoV-2 neurotropism, but no studies have demonstrated vagus nerve neuropathy as a cause of persistent chronic cough or other COVID-19 long-term effects.

Objective
The main objective was to assess the involvement of the vagus nerve neuropathy as a cause of chronic cough and other post-COVID syndrome symptoms.

Material and methods
This was a single-center observational study with prospective clinical data collected from 38 patients with chronic cough and post-COVID-19 syndrome. Clinical characteristics and laryngeal electromyographic findings were analyzed.

Results
Clinical data from 38 patients with chronic cough after 12 weeks of the acute phase of COVID-19 infection were analyzed. Of these patients, 81.6% suffered from other post-COVID conditions and, 73.6% reported fluctuating evolution of symptoms. Laryngeal electromyography (LEMG) of the thyroarytenoid (TA) muscles and cricothyroid (CT) muscles was pathological in 76.3% of the patients. Of the patients with abnormal LEMG, chronic denervation was the most frequent finding (82.8%), 10.3% presented acute denervation signs, and 6.9% presented myopathic pattern in LEMG.

Conclusions
LEMG studies suggest the existence of postviral vagus nerve neuropathy after SARS-CoV-2 infection that could explain chronic cough in post-COVID syndrome.

Published: March 2023

A 48-year-old female, known to be diabetic and hypertensive presented with chronic intermittent abdominal pain in the left upper quadrant for 2 years. The ache was dull and colicky, which was on and off in nature. It has been worsened in the previous 2 months and sometimes associated with nausea and diarrhoea during the onset. She also reported that pain increases during food intake and sometimes it was radiating to the left lumbar region. There was no history of other associated symptoms and no history of any abdominal surgeries. Family history were unremarkable.
On examination patient was alert, conscious and oriented with normal vitals. Per abdomen was soft and distended, mild tenderness over epigastrium and left hypochondrium. There was no guarding or rigidity, no mass palpable or organomegaly. Other systems were within normal limits and laboratory tests showed normal findings.
Patient had taken USG abdomen initially and it was found to be normal. Later CECT abdomen taken which showed cluster of bowel loops seen in continuation with proximal jejunal loops in the region of anterior pararenal space on left side, which was suggestive of paraduodenal hernia. Small bowel barium study also done which showed cluster of jejunal loops on the left side of upper abdomen.
The Impact of Marketing Mix Elements on Tourist's Satisfaction towards Five Stars Hotel Services in Dubai during COVID-19
Authors: JAHMANI Ashraf , JAWABREH Omar , ABOKHOZA Reneh , ALRABEI Ali Mahmoud 
Published: March 2023

Purpose: Tourist satisfaction measures the prosperity of a business and tourism sector. If there are many satisfied tourists, the tourism sector will profit, but if there are many less satisfied tourists, the tourism sector will lose money. Therefore, it is necessary to know the factors that affect tourist satisfaction. This study aims to develop and implement a method for five-star hotels to identify attributes that will increase tourists' satisfaction during the pandemic.
Method: The study used 100 tourists in Dubai as respondents who were selected randomly at five-star hotels. The results showed no impact of all marketing mix elements on tourist satisfaction except the physical evidence of the COVID-19 pandemic.
Outcomes: The results of this study indicated that the COVID-19 pandemic influenced five-star hotel services in Dubai and that the marketing mix elements used by the hotels are an important factor in tourist satisfaction. In conclusion, Dubai must understand the importance of a marketing mix to fulfil tourist satisfaction and improve the service that makes it more significant in the tourism industry.
Originality: Numerous modifying variables impacting the management process have been examined in the literature on complaint management. It is the first study investigating the five-star hotel in Dubai to check the operative services on how to work on tourist satisfaction and determine the impact of marketing mix elements on tourism during the pandemic.

Published: March 2023

Abstract
In this study, a diffusion operator is investigated on a star graph with
nonhomogeneous edges. First, the behaviors of sufficiently large eigenvalues
are learned, and then the solution of the inverse problem is given to determine
the potential functions and parameters of the boundary condition on the star
graph with the help of a dense set of nodal points and
to obtain a constructive solution to the inverse problems of this class.
TMT-based comprehensive proteomic profiling identifies serum prognostic signatures of acute myeloid leukemia
Authors: Zhang Wei , Liu Bei , Wu Shiwen , Zhao Li 
Published: March 2023

Abstract
Acute myeloid leukemia (AML) is classified into favorable-risk, intermediate-risk, and poor-risk subtypes. This study aimed to compare the serum proteomic signatures of the three AML subtypes and identify prognostic biomarkers for AML. Serum samples from patients with favorable-risk (n = 14), intermediate-risk (n = 19), and poor-risk AMLs (n = 18) were used for the analysis of tandem mass tag (TMT) labeling-based quantitative proteomics. Comparative analysis was performed to identify differentially expressed proteins (DEPs) between groups. Prognostic proteins were screened using binary logistics regression analysis. TMT-MS/MS proteomics analysis identified 138 DEPs. Fumarate hydratase (FH), isocitrate dehydrogenase 2 (IDH2), and enolase 1 (ENO1) were significantly upregulated in poor-risk patients compared with favorable-risk patients. ELISA assay confirmed that patients with poor-risk AMLs had higher levels of IDH2, ENO1, and FH compared with intermediate-risk AML patients. Logistics analysis identified that proteins 3-hydroxyacyl-CoA dehydrogenase type-2 (HADH, odds ratio (OR) = 1.035, p = 0.010), glutamine synthetase (GLUL, OR = 1.022, p = 0.039), and lactotransferrin (LTF, OR = 1.1224, p = 0.016) were associated with poor prognosis, and proteins ENO1 (OR = 1.154, p = 0.053), FH (OR = 1.043, p = 0.059), and IDH2 (OR = 3.350, p = 0.055) were associated with AML prognosis. This study showed that AML patients had elevated levels of FH, IDH2, ENO1, LTF, and GLUL proteins and might be at high risk of poor prognosis.

Published: March 2023

Objetivo: caracterizar o conhecimento e a prática acerca da utilização de preservativos por parte de adolescentes do sexo feminino, estudantes do ensino médio de uma escola da rede estadual do interior de Sergipe, Brasil.
Materiais e método: pesquisa de corte transversal, realizada em uma escola da rede pública localizada no interior do Estado de Sergipe, Região Nordeste do Brasil. A coleta de dados ocorreu em fevereiro e março de 2017, na escola com o maior número de adolescentes matriculados do Estado.
Resultados: entre as 94 participantes do estudo, a média de idade foi de 17,3 anos (DP = 1,2); a maioria das adolescentes referiu renda familiar mensal de até um salário-mínimo (61,3 %). A religião predominante foi a católica (74,5 %). Apenas 4,3 % das adolescentes afirmaram ter filho e uma delas encontrava-se gestante (1,1 %). Quanto à iniciação sexual, 51,1 % das adolescentes participantes referiram não ter tido as primeiras relações sexuais, enquanto 48,9 % apresentavam vida sexual ativa. A maior frequência de relações sexuais e uso de preservativo entre as adolescentes foi encontrada entre aquelas que referiram a ingesta de bebidas alcoólicas (40 [42,5 %]; p < 0,05). Sobre preservativos, 92,6 % das adolescentes conheciam e já haviam tido contato com o preservativo masculino, enquanto apenas 62,8 % conheciam e tinham visualizado o feminino.
Conclusões: as adolescentes apresentam conhecimento frágil sobre preservativos e adotam prática sexual insegura; portanto, é fundamental o desenvolvimento de estratégias de educação sexual que visem melhorar o conhecimento e as habilidades das adolescentes sobre o tema.
Long-term performance of simultaneous measurement of stable isotopes of oxygen and carbon in cellulose with a high-temperature pyrolysis/gas chromatography/isotope ratio mass spectrometry system at the Institute for Geological and Geochemical Research
Authors: Kern Zoltán , Llanos Campana Daniela Maria , Hegyi István Norbert 
Published: March 2023

AbstractA high-temperature pyrolysis/gas chromatography/isotope ratio mass spectrometry system was established at the Institute for Geological and Geochemical Research in 2013. A dedicated field of application of the system is the simultaneous measurement of stable carbon and oxygen isotope ratios in the cellulose of modern, relict and subfossil plant tissues and sediments. The measurement protocol was fine-tuned during the first year of operation and documented in detail in this report. To quantify the long-term reproducibility of the simultaneous measurement of stable isotopes of oxygen and carbon in cellulose, a 2σ range inferred from repeated measurements of a Quality Assurance standard can be recommended: 0.16 and 0.20‰, for δ13C and δ18O, respectively. An extensive set of samples with known pyrolysis-based δ13C data was analyzed in combustion mode and the paired results were used to assess the necessity of adjustment of the pyrolysis-based δ13C measurements. The variances of the two datasets were not significantly different; the slope (intercept) of the regression was indistinguishable from unity (zero), suggesting that probably owing to the relatively frequent cleaning of the pyrolysis furnace, pyrolysis-based δ13C data neither suffer from a variance bias nor require a specific adjustment.
