Foi realizado um levantamento bibliográfico sobre o mindset dos orientais, bem como uma análise acerca da utilização deste tipo de mentalidade na sociedade a qual estão inseridos, assim como uma observação de como esta mentalidade pode ser replicada e benéfica a outros. Conclui-se que são diversos os benefícios do mindset oriental e que pode até mesmo ser utilizado no âmbito emocional, psicológico e trabalhista, a fim de trazer  às pessoas um melhor estado físico e mental nas mais diversas áreas da vida e ajudar a combater dificuldades por elas enfrentadas.
PAPR Reduction in Cyclic Prefix OFDM (5G) System using Group Codeword Shifting Technique
Authors: Azlan Yusof  , Ezmin Abdullah  , Azlina Idris  , Wan Azani Mustafa
Published: September 2023

Cyclic Prefix Orthogonal Frequency Division Multiplexing (CPOFDM) is a 5G multicarrier waveform that enables high data rates and spectrum efficiency improvements. The primary drawback of CPOFDM is that it has a high peak to average power ratio (PAPR), which is a characteristic of all multicarrier modulation techniques. We study the application of a Group Codeword Shift (GCS) approach to reduce the peak to average power ratio (PAPR) in a CPOFDM system in this article. Additionally, we compared the results of peak to average power ratio (PAPR) reduction with low complexity in CPOFDM using a Group Codeword Shift (GCS) approach, Selective Codeword Shift (SCS), Median Codeword and Conventional CPOFDM.

The paper presents a continuation of the previously obtained author’s results. The dependence of the analytical approximate solution of one class of nonlinear differential equations on the perturbation of the initial data is established. A numerical experiment was carried out, confirming the theoretical results, and a variant of optimizing a priori estimates using a posteriori ones was also given. The presented results are the final stage in the substantiation of an analytical approximate solution for nonlinear differential equations that are generally not solvable in quadratures.

В работе представлено продолжение ранее полученных авторских результатов. Доказано влияние возмущения исходных данных на аналитическое приближенное решение одного класса нелинейных дифференциальных уравнений. Представлены результаты численного эксперимента, подтверждающие теоретические результаты, а также дан вариант оптимизации априорных оценок с помощью апостериорных. Представленные результаты являются завершающим этапом обоснования аналитического приближенного метода решения для дифференциальных уравнений, в общем случае не разрешимых в квадратурах.

Using the classical kinematic hypotheses of Kirchhoff, the problems of the maximum permissible states of deformation of hybrid polymetallic plates under conditions of quasi-static loading by distributed transverse pressure are considered. Plates with lenticular forms of a fixed contour are considered when they are pinched and hinged. The topology of the arrangement of phase materials corresponds to layers of constant thickness that are pairwise symmetrical with respect to the median plane. A general resolving system of differential equations for various modifications of contours has been obtained and the corresponding procedures for numerical and analytical solutions have been developed for two main permissible states of limiting deformation: 1 - limiting elastic and 2 - pre-fracture states with various modifications of the forms of fixing the contour.

При использовании классических кинематических гипотез Кирхгофа рассмотрены задачи о предельно допустимых состояниях деформирования гибридных полиметаллических пластин в условиях квазистатического нагружения распределенным поперечным давлением. Рассматриваются пластинки с чечевидцеподобными формами закрепленного контура при их защемлениях и шарнирном опирании. Топология расположения фазовых материалов соответствует попарно-симметричным относительно срединной плоскости слоям постоянной толщины. Получено общее разрешающие системы дифференциальных уравнений для различных модификаций контуров и разработаны соответствующие процедуры численного и аналитического решения для двух основных допускаемых состояний предельного деформирования: 1 – предельно-упругого и 2 – состояни предразрушения при различных модификациях форм закрепления контура.

The paper is devoted to some problems concerning modeling semi-isotropic elastic media. Several quadratic energy forms of a thermodynamic state potential are introduced in terms of pseudotensors. These energy forms are assumed to be absolute invariants with respect to arbitrary transformations of the three-dimensional Euclidean space (including mirror reflections). As a result of applying special coordinate representations of semi-isotropic (semi-isotropic) pseudotensors of the fourth rank, it is possible to determine 9 covariantly constant constitutive pseudoscalars characterizing a semi-isotropic elastic medium. The Neuber’s, conventional, first and second base natural energy forms are compared and equations are derived for constitutive scalars and pseudoscalars, including the conventional semi-isotropic pseudoscalars: shear modulus, Poisson’s ratio, characteristic microlength (a pseudoscalar of negative weight, sensitive to reflections of three-dimensional space), and six dimensionless pseudoscalars.

В работе обсуждаются некоторые вопросы моделирования полуизотропных упругих сред. Вводятся квадратичные энергетические формы термодинамического потенциала состояния. Исследуемые энергетические формы полагаются абсолютными инвариантами по отношению к произвольным преобразованиям трехмерного Евклидова пространства (в том числе, при зеркальных отражениях). В результате применения специальных координатных представлений полуизотропных псевдотензоров четвертого ранга можно определить все 9 ковариантно постоянных определяющих псевдоскаляров, характеризующих полуизотропную упругую среду. Выполнено сравнение и получены соотношения, связывающие определяющие скаляры и псевдоскаляры нейберовской, конвенциональной, первой и второй основных естественных энергетических форм, в том числе, с конвенционально используемыми полуизотропными псевдоскалярами: модулем сдвига, коэффициентом Пуассона, характерной микродлиной (являющейся псевдоскаляром отрицательного веса, чувствительным к отражениям трехмерного пространства), и шестью безразмерными псевдоскалярами.
RESEARCH OF METHODS FOR IMPROVING ENERGY EFFICIENCY AND EMISSIONS REDUCTION IN DISTRIBUTION STATION OF NATURAL GAS TRANSMISSION NETWORK
Authors: Tučkus Rapolas , Rogoža Artur
Published: September 2023

The global energy crisis, rising energy demand and climate warming make it imperative to find ways to recover energy that is not being put to beneficial use, to reduce primary and final energy consumption, and to reduce emissions. An important part of Lithuania’s energy sector is the natural gas sector and its transmission network, including the gas distribution stations (GDS). It is the GDS that has an unexploited potential for energy recovery, as the gas pressure is reduced through the use of gas pressure regulators, where the potential energy in the highpressure gas is not utilized in a useful way, and the necessary heating of natural gas is carried out through the use of natural gas boilers, with additional environmental pollution. The aim of the study is to analyse the gas distribution station, to find the areas of the station where potential energy is not being used and the environment is being polluted, and to propose reasonable solutions. Following a literature review, alternative technical solutions are selected: turbine-expander, conversion of the gas preheating system from gas boilers to a geothermal heat pump, use of solar collectors, photovoltaic solar cells. In order to assess the potential of technological solutions to improve the efficiency of the DSS and reduce emissions, a multi-criteria analysis of the proposed solutions is carried out, where the measures under evaluation are analysed in energy, economic and environmental terms. The energy assessment analyses the energy consumption, the economic assessment calculates the net present value (NPV) of the investment for each solution and the environmental assessment examines the environmental impact of the proposed measures over their life cycle. Based on the results of the multicriteria analysis, the systems best suited to the object of study (GDS) are recommended.
Capturing Statistical Isotropy Violation with Generalized Isotropic Angular Correlation Functions of Cosmic Microwave Background Anisotropy
Authors: Dipanshu  , Souradeep Tarun , Hirve Shriya
Published: September 2023

The exquisitely measured maps of fluctuations in the cosmic microwave background (CMB) present the possibility of systematically testing the principle of statistical isotropy of the Universe. A systematic approach based on strong mathematical formulation allows any nonstatistical isotropic (nSI) feature to be traced to the nature of physical effects or observational artifacts. Bipolar spherical harmonics (BipoSH) representation has emerged as an overarching general formalism for quantifying the departures from statistical isotropy for a field on a 2D sphere. We adopt a little-known reduction of the BipoSH functions, dubbed minimal harmonics in the original paper by Manakov et al. We demonstrate that this reduction technique of BipoSH leads to a new generalized set of isotropic angular correlation functions referred to here as minimal BipoSH functions that are observable quantifications of nSI features in a sky map. This paper presents a novel observable quantification of deviation from statistical isotropy in terms of generalized angular correlation functions that are compact and complementary to the BipoSH spectra that generalize the angular power spectrum of CMB fluctuations.

Published: September 2023

Cet article étudie le couple formé par Albert et Madeleine Thomas. En retrait dans l’espace public, Madeleine exerce pourtant une intense activité politique aux côtés de son mari. L’engagement politique d’Albert s’appuie ainsi sur une véritable entreprise familiale et conjugale qui repose néanmoins sur une répartition des tâches asymétriques. Après le décès d’Albert en 1932, Madeleine cherche à perpétuer la mémoire de son défunt mari. Ce parcours conjugal original invite à réévaluer l’importance du travail politique effectué par Madeleine Thomas ainsi que son rôle d’infatigable passeuse de mémoire qui l’insère dans les cercles politiques et intellectuels français et internationaux.

Cet article revient sur une expérimentation de développement syndical originale issue d’un partenariat entre un syndicat non représentatif, mais fortement implanté dans le secteur du nettoyage, et une association issue du community organizing . À travers une enquête empirique, ce travail revient sur l’intérêt qu’il y a pour les organisations syndicales à recourir à un acteur proposant des « solutions » clés en main et a priori efficaces pour susciter de nouvelles adhésions dans des secteurs fortement précarisés. Ce faisant, il révèle les décalages et les tensions suscités par les diverses traditions militantes et souligne l’existence d’une véritable concurrence sur le terrain des luttes syndicales des précaires en France.
Restless Mind: Hu Shi and Sinified Liberalism in Modern Chinese Intellectual History
Authors: Lu Xia
Published: September 2023

Impossible de considérer la promotion, l’essor et le développement des idées libérales en Chine au xx e  siècle sans prendre en compte la figure de Hu Shi (1891-1962) et l’influence que son œuvre exerça. Pendant toute sa vie intellectuelle, Hu Shi se tint au premier rang des intellectuels chinois désireux de moderniser leur pays. Parti se former aux États-Unis très tôt, il concentra ses recherches sur les (r)évolutions littéraires et entreprit d’analyser l’histoire de la philosophie chinoise avec les méthodes scientifiques occidentales. Il entendait non seulement changer les façons de parler et d’écrire dans le monde académique, mais encore les styles de pensée et de vie au sein de la population chinoise. Il devint l’un des plus prestigieux intellectuels de la Chine moderne, en s’engageant activement dans la vie politique. Il poursuivitl’idéal d’une « bonne gouvernance », même en régime de parti unique. L’invasion par le Japon interrompit ses efforts et la guerre civile le mit en difficulté, quoiqu’il ait aidé dans une certaine mesure à restaurer l’autorité d’une administration centrale indispensable à un pays en voie de développement au territoire immense et à la population énorme : les efforts à déployer pour le moderniser vite et fort sont à cette mesure. Hu Shi dut quitter la Chine continentale. Dans les dernières années de sa vie, il fut un symbole de la relation entre les États-Unis et le régime du Kuomintang à Taïwan, mais nombre de ceux qu’il avait formés et qui étaient restés en Chine continentale critiquaient sa position, au sein de la communauté académique. Or Hu Shi prit lui-même ses distances avec le Kuomintang (KMT dans cet article), en levant toujours haut la bannière du libéralisme et d’une « Chine libre ». Classification JEL  : B13, B31, N25, P26
Patient-Reported Outcomes and Computed Tomography Review After Minimally Invasive Fusion of the Sacroiliac Joint With Aggressive Joint Decortication and Joint Compression
Authors: Cross William W. , Tomov Marko N. , Hung Michelle Y. , Muir Jeffrey M.
Published: September 2023

The sacroiliac joint (SIJ) is a common, underrecognized source of low back pain. We evaluated outcomes in patients undergoing sacroiliac joint fusion (SIJF) using a novel, minimally invasive SIJF system emphasizing compressive forces across an aggressively debrided SIJ. We retrospectively reviewed data from a continuous set of patients presenting to a large, tertiary care hospital from September 2017 to August 2019. All patients received the novel SIJF device. Outcomes were assessed at 8 weeks, 6 months, and 12 months using the Oswestry Disability Index (ODI) score, Numerical Rating Scale (NRS) score, Single Assessment Numerical Evaluation (SANE) score, and Patient-Reported Outcomes Measurement Information System (PROMIS) measures, plus radiographic evaluation of fusion status. Data from 75 patients were analyzed. At 8 weeks, 6 months, and 12 months, the ODI score improved by 10.5 points (
P
=.002), 17.4 points (
P
<.0001), and 23.6 points (
P
<.0001), respectively, while the NRS score improved by 4.6 points (
P
<.0001), 4.4 points (
P
<.0001), and 4.6 points (
P
<.0001), respectively. SANE scores indicated high levels of patient satisfaction (81.0%, 92.18%, and 89.2%, respectively). PROMIS physical function scores improved by 2.65 points, 3.30 points, and 3.63 points, respectively, while PROMIS mental health scores showed changes of −1.93 points, 1.57 points, and −0.47 points, respectively. A review of computed tomography scans demonstrated grade 3 fusion (complete) in 81% of cases at a mean of 371 days postoperatively. There was one revision case for a malpositioned implant. The use of a novel SIJF device emphasizing compressive forces provided early, durable improvements in patient-reported outcomes and extremely high patient satisfaction. [

Standardized Nursing Examination Remediation: A Program Evaluation
Authors: Olsen Jeanette M. , Mota Dalete , Wildenberg Catherine , Donahue Rita J. , Thomas Regan , Willmus Nicole
Published: September 2023

Background:

Nurse educators at a public university expanded their standardized examination program in Spring 2020 to include more specialty examinations, required remediation, and retesting for students who did not attain benchmark scores. This study conducted a remediation-focused program evaluation.

Method:

A mixed-methods design was used. Aggregated deidentified Health Education Systems, Inc. (HESI) specialty examination scores (
n
= 907) were analyzed. Feedback from nursing students and recent alumni (
n
= 70) was collected using a Qualtrics survey.

Results:

For students scoring under benchmark, higher remediation time requirements led to greater increases in second-attempt specialty examination scores. More alumni than current students reported remediation was helpful (
p
= .029). Participants' perspectives regarding remediation barriers, helpful strategies, and motivating policies were identified. Five themes emerged from open-ended survey comments, adding depth to the quantitative findings.

Conclusion:

Recommendations for standardized examination remediation strategies and policies are offered.

A preliminary study of porous ceramics with carbon black contents
Authors: Jalaluddin Mohamed Lokman , Azlan Umar Al-Amani , Rashid Mohd Warikh Abd
Published: September 2023

This paper is a study of porous ceramics from a mixture of clay (kaolinite), silica (silicon dioxide), and feldspar by adding the carbon black (CB) with different contents. The results were presented in terms of apparent porosity, relative density, microstructure and porous characteristic, flexural strength and phase formation. As observed, the sintering at 1200 ℃ is the optimum temperature in this work. In comparison to the samples without CB content, the apparent porosity and relative density of ceramics are highly dependent on the CB contents. This might be attributed to the presence of porous structure as seen in SEM images on the fracture surface of ceramics. It also revealed that the addition of CB resulted in smaller pore sizes and a more uniform pore distribution. The creation of pores in porous ceramics was mainly attributed to the loss of shape of CB microspheres at high temperatures, as observed from SEM. The flexural strength of the sintered samples exhibited an average decrease from 60 to 55 MPa due to the presence of CB, which is typically known to reduce the mechanical properties with high porosity. In XRD results, the muscovite phase is represented by a few of peaks with significant intensities, while the rest peaks are of undetermined phase. The strongest peak at a 26° of 2θ angle, suggesting the presence of potassium and aluminium in the form of silicate minerals.
A Synechistic Conceptualization of Othering: Social Ontological Questions in Service Learning
Authors: Bernasconi Claudia , Blume Libby Balter
Published: September 2023

Expanded conceptions of I-Other relationships in critical service learning impact ideas of self, ways in which self is understood to be autonomous or relational, and holistic concepts of self and other/s. This manuscript engages core ontological questions in contemporary service learning: Can social epistemological and ontological approaches assist in questioning oppositional framings of us and them that are both the cause and the consequence of exclusion and individualism, such as “us doing for them” or “us thinking of them”? Two distinct conceptions of self+other emerged from a recurrent service-learning course offered to graduate architecture students:  a “dichotomic conceptualization” of self/other, and a “synechistic conceptualization” of self-in-other. Architecture students interrogated their roles as designers and community members and their own lived experience as they intersect issues of racial identity, education, and socio-economic status. We conclude that a synechistic service learning approach counteracts narcissistic and competitive approaches in architecture and design education.
The Impact of ERP Systems on Organizational Performance
Authors: Nour Mohamed Abdalla
Published: September 2023

Research on the link between investments in ERP systems and organizational performance has often led to mixed results. Besides internal organizational factors, many external contextual factors come into play. This study examined the role of firm size, industry, and duration of ERP system's use in influencing the performance impact of ERP systems through moderating the relationships between antecedent variables, ERP-induced benefits, and improvement in overall organizational performance. Using a sample of 200 participant firms, and structural equation modeling (SEM) analysis, the author confirmed the significant role of business process re-engineering and organizational fit and alignment as antecedents to ERP-induced benefits in information quality, and coordination/integration. Data and information quality was in turn confirmed as a significant predictor of organizational performance. Furthermore, the roles of industry, firm size, and time elapsed were also confirmed as significant moderators to the influence of the antecedent variables on ERP benefits and organizational performance.
On PDF/A Conformance and Font Usage in PDF Documents Provided by Public Sector Organizations
Authors: Fischer Thomas , Lundell Björn , Gamalielsson Jonas
Published: September 2023

The use of appropriate fonts and file formats for long-term maintenance of digital assets is a challenge for organizations in the public sector. The article reports from a study which investigated the PDF/A conformance and font usage in PDF files provided by Swedish public sector organizations (PSOs). This article presents an analysis of the PDF files' properties and font usage including a categorization of fonts' licenses. This study is motivated by the PDF/A-1 standard's requirement that ‘only fonts that are legally embeddable in a file for unlimited, universal rendering shall be used.' Analyzing PDF sets from three PSOs, the finding shows that the proportion of files that claim or succeed at conforming to PDF/A greatly varies among the sets despite similar backgrounds. Although the most popular way to make use of fonts is by embedding a subset of the font data, for some fonts expected to be ‘always available,' a considerable proportion of PDF files does not include any font data. This puts the onus of locating this data on the PDF reader which is problematic for long-term archival.
Parametric Modelling of Rousselier ́s Damage Model Parameters with Instrumented Charpy Tests
Authors: Cuamatzi-Melendez Ruben
Published: September 2023

This work presents Rousselier´s damage model parameters effect and their physical meaning on Charpy fracture propagation curves. Therefore, instrumented Charpy tests were performed at room test temperature to measure the load-displacement curve. The parameters were measured from a Grade A ship plate steel, employed for the construction of merchant ships. The effect of Rousselier´s model parameter was done by performing cellular automata finite element (CAFE) modelling, where Rousselier’s damage model was coded, and therefore Rousselier´s model parameters were incorporated using random number generators in the ductile arrays of cells, using Weibull distributions. Consequently, in each CAFE simulation, the model evaluates random values of Rousselier´s damage model parameters performing a more physically based modelling. The results showed that the present CAFE modelling was able to reproduce the hardening and fracture propagation regions of instrumented Charpy data. Furthermore, the present work showed a suitable Rousselier´s damage model parameters calibration procedure with Charpy data, and how each Rousselier´s model parameter can affect the hardening and fracture propagations regions when they are not properly calibrated, producing unrealistic results. Additionally, it can be observed that the present results can be used as a template for a better calibration of Rousselier´s damage model parameters in CAFE modelling.
A Novel Methodology for Fault Sensing in Presence of Power Swing for Transmission Line with Thyristor Controlled Series Compensator
Authors: Akolkar Sonali , Jariwala Hitesh
Published: September 2023

Digital distance relaying is implemented in extra high voltage (EHV) transmission network for speedy and reliable fault detection. But it should not activate in case of slow transients known as power swings. However, for occurrence of any type of fault during power swing, the relay should sense the faulty condition and send trip command to concerned circuit breaker. The detection of fault in a transmission line network with TCSC during the power swing condition has become further complex due to transients generated by series capacitor and the metal–oxide varistor (MOV) protecting it. This paper firstly presents effect of TCSC on distance relay operation for varied TCSC degree of compensation and firing angle values. Further, a discrete wavelet transform-based fast acting fault and swing classification algorithm is proposed which can sense all types of faults during slow as well as fast power swing in first decomposition level and within 0.001 sec. The proposed utilizes optimized threshold values both for swing and fault sensing by using Honey Bee Optimization Algorithm (HBOA). The proposed novel algorithm is coded in MATLAB software and the test system comprising of 400kV, 50Hz parallel transmission line network along with TCSC is built using MATLAB Simulink environment with sim power systems toolbox. It is tested for high/low resistance faults, symmetrical/asymmetrical faults and close-in/far end faults by changing TCSC compensation level and firing angle value. The simulation results prove the accuracy of proposed methodology for swing and fault classification.

The rete ovarii is the counterpart of the male rete testis that develops from the primary sex cords of female animals. Pathological conditions of the rete ovarii are rarely reported in dogs. This communication describes a cystadenofibroma of a rete ovarii in a 2-year-old, intact, crossbred bitch presented to the Veterinary Teaching Hospital, University of Peradeniya. The bitch was presented with complaints of hyporexia, constipation, purulent vaginal discharges and progressive abdominal distension for three weeks. A tentative diagnosis of pyometra with concurrent uterine cyst/neoplasia was arrived based on the clinical examination and imaging findings. An exploratory laparotomy revealed that the space of the right ovary is occupied by a large, 14 cm x 16 cm, smooth surfaced, spherical mass and ovariohysterectomy was performed. Histopathology findings of the cyst suggested a cystadenofibroma of rete ovarii. To the authors’ knowledge, this is the first report of canine cystadenofibroma in rete ovarii in Sri Lanka.
The Eotaxin-1/CCR3 Axis and Matrix Metalloproteinase-9 Are Critical in Anti-NC16A IgE-Induced Bullous Pemphigoid

Published: September 2023

Bullous pemphigoid (BP) is the most common autoimmune bullous skin disease of humans and is characterized by eosinophilic inflammation and circulating and tissue-bound IgG and IgE autoantibodies directed against two hemidesmosomal proteins: BP180 and BP230. The noncollagenous 16A domain (NC16A) of BP180 has been found to contain major epitopes recognized by autoantibodies in BP. We recently established the pathogenicity of anti-NC16A IgE through passive transfer of patient-derived autoantibodies to double-humanized mice that express the human high-affinity IgE receptor, FcεRI, and human NC16A domain (FcεRI/NC16A). In this model, anti-NC16A IgEs recruit eosinophils to mediate tissue injury and clinical disease in FcεRI/NC16A mice. The objective of this study was to characterize the molecular and cellular events that underlie eosinophil recruitment and eosinophil-dependent tissue injury in anti-NC16A IgE-induced BP. We show that anti-NC16A IgEs significantly increase levels of key eosinophil chemoattractants, eotaxin-1 and eotaxin-2, as well as the proteolytic enzyme matrix metalloproteinase-9 (MMP-9) in the lesional skin of FcεRI/NC16A mice. Importantly, neutralization of eotaxin-1, but not eotaxin-2, and blockade of the main eotaxin receptor, CCR3, drastically reduce anti-NC16A IgE-induced disease activity. We further show that anti-NC16A IgE/NC16A immune complexes induce the release of MMP-9 from eosinophils, and that MMP-9–deficient mice are resistant to anti-NC16A IgE-induced BP. Lastly, we find significantly increased levels of eotaxin-1, eotaxin-2, and MMP-9 in blister fluids of BP patients. Taken together, this study establishes the eotaxin-1/CCR3 axis and MMP-9 as key players in anti-NC16A IgE-induced BP and candidate therapeutic targets for future drug development and testing.
Importance of assessment of carotid plaques in the managementof acute ischemic stroke: floating intracarotid plaque
Authors: Eltemamy Marwa , Namushi Robert , Saravanan Narayanamoorthi
Published: September 2023

Mobile atheromatous plaques affecting large arteries are a major risk factor for embolic strokes. We report a case of extensive embolic cerebral infarction secondary to a vulnerable internal carotid artery plaque. A 67-year-old female was admitted with sudden left-sided weakness. A computed tomography brain scan revealed early ischemic changes in the right middle cerebral territory. The ultrasound Doppler showed soft mobile plaque with thrombus in the right internal carotid artery causing 90% stenosis. Magnetic resonance imaging brain scan performed later showed extensive right cerebral infarction. A computed tomography angiogram revealed ulcerated non-occlusive soft tissue plaque in the right internal carotid artery. She was also diagnosed with bladder cancer during this admission and was managed medically due to her performance status. Unstable vulnerable plaques can be symptomatic even in the absence of significant carotid stenosis. Hence, early identification of the plaque vulnerability, using new imaging modalities, and its medical stabilization can help to reduce the risk of cerebrovascular insults. The etiopathogenesis of inflammation within unstable vulnerable plaques and its concordance with inflammatory markers is still unclear. It is feasible in our case the malignantprocess could also be contributing to the inflammation within the blood vessels promoting vulnerability of the plaques.
Dalla montagna al topolino: commento a ‘Consensus conference sulle terapie psicologiche per ansia e depressione’
Authors: Papini Silvia Paola , Vanni Fabio
Published: September 2023

Il presente lavoro vuole costituire una lettura critica della Consensus conference sulle terapie psicologiche per ansia e depressione che è oggi un documento ufficialmente assunto dal Ministero della Salute e dunque fa da riferimento per gli operatori del settore. Questa autorevolezza formale rende opportuno che il documento venga conosciuto e valutato in modo approfondito. Vengono qui analizzati i principali ambiti trattati distinguendo fra la relazione per la giuria e le raccomandazioni assunte dalla giuria stessa. Come vedremo vi è grande distanza fra le due parti come i giudici stessi hanno colto. Ma altri aspetti riteniamo meritino attenzione: l’insufficiente approfondimento sull’infanzia e l’adolescenza, la prospettiva ristretta assunta rispetto al tipo di studi ritenuti utili, le raccomandazioni sulla formazione. Limiti che definiamo gravi e che rendono il documento, pur animato dalle migliori intenzioni, almeno in apparenza, un testo scarsamente convincente che necessita di ampie revisioni per raggiungere standard accettabili.

Attraverso questo commento al caso clinico vorrei provare ad ampliare lo sguardo rispetto a questa ricerca di Lia e definire un bisogno più generale di riconoscimento dei propri vissuti e delle proprie scelte. Sotto questo cappello possiamo certamente inserire la figura paterna, ma possiamo allargarci fino a comprendere anche un più ampio autorizzarsi che sembra passare per il riconoscimento da parte dell’altro.

Authors: Qibi Leqaa H. , Hasan Lamiaa A. , Dewachi Zaid
Published: September 2023

OBJECTIVES:

In order to assess the changes in tooth orthodontic adhesive interface microleakage after applying a caries resin penetrated to the sound enamel tooth surface in different storage media.

MATERIALS AND METHODS:

A total of 60 human maxillary first premolars (orthodontic extraction) were collected by random separation of the teeth into two equal groups. The control group was classified into three subgroups (n = 10) (control in deionized water, control in milk, and control in energy drink), while the experimental one (treated with ICON) was categorized into three subgroups (n = 10) (ICON in deionized water, ICON in milk, and ICON in energy drink) incubation phase lasted three weeks in total.

RESULTS:

A one-way analysis of variance (ANOVA) yielded a significant difference between all experimental subgroups (ICON in deionized water, ICON in milk, and ICON in energy drink) and control subgroups (control in deionized water, control in milk, and control in energy drink). The control group in the energy drink subgroup had the highest mean microleakage value when compared to the other subgroups, whereas the resin-infiltrated group in deionized water had the lowest mean value. According to the results of the T-test, ICON pre-treatment tooth samples had significantly lower mean values of microleakage than non-ICON tooth samples.

CONCLUSIONS:

The adhesive system (control group) revealed that a resin infiltrate on a sound enamel surface prior to orthodontic bracket bonding reduced bracket tooth interface microleakage in all examined samples. The ICON-infiltrated surface was discovered to provide a secondary preventive strategy against white spot lesion development by reducing microleakage under brackets.

AIMS:

To evaluate the effect of adding vanillin nanoparticles on the antimicrobial and mechanical properties of the orthodontic adhesive.

MATERIALS AND METHODS:

Transbond XT orthodontic adhesive (3M Unitek, Monrovia, California, USA) was modified with 1% and 2% vanillin nanoparticles. The chemical composition and degree of chemical conversion in orthodontic adhesive before and after adding vanillin nanoparticles to orthodontic adhesive were measured using Fourier transformation infrared spectroscopy (FTIR). Mechanical properties of unmodified orthodontic adhesive (UMOA) and 1% and 2% vanillin-modified orthodontic adhesive (VMOA) were assessed in shear bond strength (SBS) and tensile bond strength (TBS). The antimicrobial properties were evaluated using a Mueller–Hinton plate swapped with streptococcus mutans. The zone of bacterial inhibition for UMOA, 1% VMOA, and 2% VMOA was measured. Descriptive statistics, multiple comparisons, one-way ANOVA, and post hoc Duncan's test were used to compare among the results.

RESULTS:

FTIR showed no chemical conversion of 1% VMOA and 2% VMOA. There was significant streptococcus mutans growth inhibition in 1% VMOA and 2% VMOA compared to UMOA. No significant difference in streptococcus mutans growth inhibition in 1% VMOA and 2% VMOA. The SBS decreased significantly in 1% VMOA compared to UMOA. In addition, SBS decreased insignificantly when comparing 1% VMOA and 2% VMOA. TBS significantly reduced in 2% VMOA compared with UMOA. In addition, there was no significant difference in TBS between UMOA and 1% VMOA, and 1% VMOA and 2% VMOA, respectively.

CONCLUSIONS:

The 1% VMOA has improved antimicrobial properties and kept mechanical properties of orthodontic adhesive within the acceptable level.
Chronodentistry through orthodontic perspective: A literature reviews
Authors: Gauthami K , Soans Crystal R. , Krishnamurthy Shamyuktha , Ravi MS
Published: September 2023

The human body possesses a unique set of machinery called the molecular/biological clocks that function on a regular 24-h basis forming a circadian rhythm (CR). This aids in coordinating the human biological system with ever-changing environmental conditions, thereby maintaining a balance in its functioning. The central/core component of this system is known to be in the suprachiasmatic nucleus of the hypothalamus with a few aides in the periphery. The periodontal ligament in humans, being one of the dynamic oral tissues, has been shown to exhibit this self-sustained, innate oscillatory behavior that has gained significant attention from dental surgeons. Though substantial evidence regarding its precise role in maintaining circadian periodicity is still unclear, its indispensable role in dentofacial functioning cannot be denied. This review is an attempt in bringing to light the possible role of circadian periodicity in the functioning of oral tissues in the field of orthodontics with a special focus on its role in bone remodeling, orthodontic tooth movement, orthopedic and functional appliances, pain management, and their clinical implications. This could provide a better understanding of the various physiologic and pathologic processes and help us refine our approach toward orthodontic diagnosis and therapeutics. This review would therefore serve as an overview, opening more avenues for further research on this topic that can greatly help the orthodontic fraternity.
Photographic Frankfort plane subnasale pogonion (FSA) angle for assessment of anteroposterior discrepancies in malocclusion subjects: A prospective study
Authors: Rebekah R , Jain Ravindra Kumar , Balasubramaniam Arthi , Sreenivasagan Swapna
Published: September 2023

INTRODUCTION:

Anterior-posterior discrepancy assessment is a crucial component of orthodontic diagnosis and is often carried out using hard tissue cephalometric analysis. The purpose of this study was to compare the photographic Frankfort plane subnasale pogonion (FSA) angle with established cephalometric parameters to determine the accuracy of the angle in determining maxillomandibular anteroposterior discrepancies.

MATERIALS AND METHODS:

In this prospective study, a total of 60 subjects, 20 in each skeletal sagittal malocclusion, were included in the final sample based on the selection criteria. Both photographic and cephalometric records were taken, and the parameters assessed were the beta angle, Steiner's analysis, the ANB (A point- Nasion- B point) angle in the cephalograms, and the FSA angle in the profile photographs. Statistical analysis was done with SPSS software. The correlation between the measured parameters was assessed using Pearson's correlation test.

RESULTS:

A high positive and significant correlation between the FSA angle and beta angle (r = 0.793) was noted, and a high negative and significant correlation between the FSA angle and ANB angle (r = -0.848) was noted.

CONCLUSION:

The photographic FSA angle can be used as a reliable parameter to diagnose anteroposterior discrepancies.
EEG Emotion Recognition based on Multi scale Self Attention Convolutional Networks
Authors: Chao Hao , Yuan Fang
Published: September 2023

A multi-view self-attention module is proposed and paired with a multi-scale convolutional model to builda multi-view self-attention convolutional network for multi-channel EEG emotion recognition. First, timeand frequency domain characteristics are extracted from multi-channel EEG signals, and a three-dimensionalfeature matrix is built using spatial mapping connections. Then, a multi-scale convolutional network extractsthe high-level abstract features from the feature matrix, and a multi-view self-attention network strengthensthe features. Finally, use the multilayer perceptron for sentiment classification. The experimental results revealthat the multi-view self-attention convolutional network can effectively integrate the time domain, frequencydomain, and spatial domain elements of EEG signals using the DEAP public emotion dataset. The multi-viewself-attention module can eliminate superfluous data, apply attention weight to the network to hasten networkconvergence, and enhance model recognition precision.
Implementation and Outcomes of an Empiric Ivermectin Strongyloides Treatment Protocol for Patients Receiving High-Dose Corticosteroids for Severe COVID-19

Published: September 2023

Strongyloides stercoralis is a parasitic roundworm that is present worldwide and can cause lifelong, often asymptomatic, infection. Immunosuppression, particularly by corticosteroids, is a risk factor for hyperinfection syndrome and disseminated strongyloidiasis—severe disease states that can lead to septic shock and death. Our institution implemented a strongyloidiasis screening and empiric ivermectin treatment protocol for inpatients receiving high-dose corticosteroids for severe COVID-19. Among 487 COVID-19 admissions treated with high-dose corticosteroids from June 10, 2020 to March 31, 2021, 61% of those with demographics at risk for Strongyloides exposure were screened for Strongyloides and treated empirically with ivermectin. Adherence to the protocol declined over time during the study period. The empiric ivermectin protocol appeared safe, but more research is needed to determine the effect on hyperinfection and/or disseminated strongyloidiasis risk and mortality rate, as well as to improve institutional adherence to the protocol.
Analysis and Testing of Optimal Power Control Strategy for NASA Moon Base Interconnected DC Microgrid System

Published: September 2023

As a part of NASA’s efforts in space, options are being examined for an Artemis moon base project to be deployed. This project requires a system of interconnected, but separate, DC microgrids for habitation, mining, and fuel processing. This in-place use of power resources is called in-situ resource utilization (ISRU). These microgrids are to be separated by 9-12 km and each contains a photovoltaic (PV) source, energy storage systems (ESS), and a variety of loads, separated by level of criticality in operation. The separate microgrids need to be able to transfer power between themselves in cases where there are generation shortfall, faults, or other failures in order to keep more critical loads running and ensure safety of personnel and the success of mission goals. In this work, a 2 grid microgrid system is analyzed involving a habitation unit and a mining unit separated by a tie line. A set of optimal controls that has been developed, including power flow controls on the tie line, dispatch of PV generation, and dispatch of non-critical loads, is analyzed, and validated in hardware on the Secure Scalable Microgrid Testbed (SSMTB). This testbed includes hardware emulators for a variety of energy sources, energy storage devices, pulsed loads, and other loads.
