No full textThis paper deals with a marriage ritual of the Dayak Barai tribe, known as Tikah Kawitn. The purpose of this paper is to explore the local wisdom and values behind the marriage customs of the Dayak Barai tribe and to find their relevance for appreciating and living the values of Catholic marriage. This paper uses the Interpretative Phenomenological Analysis (IPA) method. The author finds that the Dayak Barai tribe values the nobility of traditional marriages. It can be seen in pre-wedding rituals and marriage ceremonies designed with symbolic actions. The Tikah Kawitn ritual also contains the essential values of marriage as taught by the Catholic Church, namely monogamy, not being divorced, directed at heredity, and the welfare of the household. The author concludes that the values of the traditional marriage of the Dayak Barai tribe, tikah kawitn, can contribute to the process of deepening and appreciating the nobility of the Catholic Church's marriage, especially for the Dayak Barai tribe who are Catholic
The traitors
No full textIn this political essay the author analyses who and when were the traitors in Russia since the collapse of the Soviet Union. The essay is influenced by the documentary film
made by Maria Pevcik who claimed that the path to Kremlin for Putin was paved by the surroundings of Boris Jelcin in the 1990s. The author also wonders who would be the traitors of liberal Lithuania today. At last the essay provides the perspective of Putin and how he sees traitors today in the context of the war in Ukraine.Vytauto Didžiojo universitetas / Vytautas Magnus UniversitySocialinės ir politinės kritikos centras / Centre for Social and Political CriticismPolitikos mokslų ir diplomatijos fakult. / Faculty of Political Science and Diplomac

Creep resistance and strain-rate sensitivity of nanocrystalline materials
No full textA micromechanics-based continuum model is developed to determine the creep resistance and strain-rate sensitivity of the nanocrystalline materials. The solid is idealized as a two (or three) phase composite, where the grains were treated as spherical inclusions, the grain boundary as the matrix and the pores/voids as the third phase (if present in the solid) of the composite. The strain of an individual phase is taken to be the sum of elastic and creep/viscoplastic components. Within the elastic context the homogenization scheme is developed based on the Eshelby-Mori-Tanaka approach. The Laplace transform was used to convert the linear elastic homogenization
method to a linear viscoelastic one, and then to convert the viscoelastic response to viscoplastic one, during which the Maxwell viscosity of the viscoelastic phases is replaced by the secant viscosity of the viscoplastic phases. A nonlinear-rate dependent constitutive equation is assumed for both the grain interior and grain boundary to calculate the secant viscosity of the individual phase at a given stage of deformation. The drag stress of the grain interior is assumed to follow the Hall-Petch effect, but that of the grain boundary phase is taken to be size-independent. By using the field-fluctuation method, the effective stress (or effective strain rate) of the constitutive phase is derived in terms of the applied stress (or applied strain rate). The change in porosity under different loading conditions is also incorporated within the model.
The validity of the model was verified by comparing the predicted stress-strain results with the experimental data of Sanders et al. [42], Wang et al. [43] and Wang et al. [44] for the creep response, and Khan et al. [48] and Khan and Zhang [49] for the constant strain-rate loading. The model is capable of capturing both hardening and softening of material as grain size decreases from coarse grain to the nanometer range. The latter characteristic is also known as the inverse Hall-Petch effect and this occurs in both creep and constant strain-rate response. As a result, the critical grain size at which the solid has maximum strength can be estimated using this method. With the presence of porosity, the developed model is also able to capture the nonlinearity in the stress-strain plot under hydrostatic loading.M.S.Includes bibliographical references (p. 94-98)
Empirical relations for the propagation characteristics of diffused channel waveguides
No full textEmpirical relations for the propagation constant and the field profile parameters of integrated optical diffused channel waveguides have been developed. The field profile used is the evanescent secant-hyperbolic field, which has been shown earlier to be a very good approximation for diffused channel-waveguide modes. Least-square fitting has been used to obtain the empirical relations. The results show that the error in empirical relations for the propagation constant is within 2% for a broad range of waveguide parameters. The obtained empirical relations for the field profile and the propagation constant have been used, as an example, to calculate the coupling length of diffused channel-waveguide-based directional couplers
Wavelet-Galerkin solver for the analysis of optical waveguides
No full textA new set of basis functions based on truncated Gaussian wavelets is proposed for optical waveguide analysis using the well-known Galerkin method. A spatially limited Gaussian wavelet train is formed by judiciously truncating the tails of Gaussian functions. The proposed set of basis functions produces a sparse eigenvalue equation when the wave equation is solved by the Galerkin method. The limited span of the basis functions makes the computation of integrals associated with matrix elements very fast with lower memory requirements. The effectiveness of the proposed basis functions is tested by comparing the results with those obtained by other methods and other basis functions for diffused and step index planar and channel waveguides. The results show a significant reduction in computation time while maintaining good accuracy
Improved optimal variational method to analyze optical rib waveguides
No full textWe present an improved optimal variational method (Vopt) to overcome the assumption of field separability in the two orthogonal directions. The improved Vopt method is shown to give accurate results with less computational effort. The method is applied to rib waveguides and the results are compared with those obtained using the computationally intensive finite-element method

Abstract:
Objective: The objective of this scoping review is to describe and explore the breadth and extent of the evidence for ultrasound-guided arthrocentesis (UGA) in the Emergency Department (ED).
Introduction: Joint aspiration or arthrocentesis procedures are commonly performed in the ED for diagnosis and management of painful joints. The integration of ultrasound technology to arthrocentesis has ensured improved patient care and reduced complications.
Inclusion criteria: This scoping review will examine all articles in the English language published between January 2013 and December 2023. We will include human studies in peer reviewed journals and grey literature.
Inclusion criteria:
To define key elements required for our scoping review, including the population, concept, and context (PCC) related to the purpose of the review, we have drawn on guidance within the JBI Manual for Evidence Synthesis (Aromataris and Munn, 2020) when defining our inclusion criteria. Items to be included will meet the following criteria:
1. Population: Adult and paediatric patients who attended ED with joint pain or effusion
2. Concept: The use of ultrasound technology for arthrocentesis.
3. Context: ED.
4. Studies reporting on at least one of the following outcomes:
Clinical indications and feasibility of UGA in the ED.
Procedural success rates of UGA compared to traditional approaches.
Safety outcomes associated with UGA in the ED.
Resource implications of implementing UGA in the ED.
5. Evidence: Peer-reviewed articles including original theoretical or empirical research, randomized controlled trials, non-randomized controlled trials, observational studies, case series, or other quantitative, qualitative, mixed-methods, and experimental research. This will be supplemented by available relevant grey literature.
6. Articles are published in an identifiable academic or scholarly journal while grey articles will be collected from relevant governments and institutions and policymakers;
7. Language: We will include English publications only due to the language fluency of the researchers and lack of funding for language translation.
8. Time-frame 11 years since January 2013. If necessary, we may extend the timeframe to expand search results.
Exclusion criteria:
1. Those studies performed outside ED e.g. in the operating theatre, outpatient clinics, and inpatient wards.
2. Studies where ultrasound was not used for arthrocentesis
3. Secondary articles such as review articles
4. Non-empirical and non-peer-reviewed works, and works situated as opinion-based commentaries, viewpoints, editorials, and perspective pieces, letter to the editor etc.
5. Books, book reviews, and book chapters including government reports, dissertations/theses, conference abstracts, websites, environmental scans, etc.;
6. Studies not reporting on at least one of the specified outcomes
7. Language: Published in a language other than English;
8. Articles published prior to January 1st 2013. This is to ensure that only contemporary literature is considered for analysis.
9. Regarding the inclusion of grey literature, the research team understands the potential to reduce the risk of bias, and acknowledges that including grey literature is usually desired or required for evidence syntheses for highlighting a broader picture of evidence.
Methods: We will apply PRISMA ScR guidelines and Joanna Briggs Institute (JBI) guidelines for this scoping review. A medical librarian will construct a robust and replicable search strategy of contemporary literature in key clinical databases. We will register the protocol in the Open Science Framework (OSF). In addition, we will perform literature review and analysis through rayyan.ai with collaboration of all authors. We will present the qualitative data in charts, tables and figures including the PRISMA ScR flow chart. Two reviewers will perform review independently in a predesigned data charting form, with any discordance to be reviewed by a third investigator.
Conclusion: This scoping review will provide an overview of recent advances in ultrasound-guided arthrocentesis, highlighting their various techniques, efficacy, safety, and potential applications in ED. In addition, it will identify gaps in the literature and highlight areas for future research to improve patient care
Process Model Accuracy Enhancement Using Cluster Based Approach
No full textFull chip resist simulation is a critical step in the lithography simulation of advanced CMOS technology nodes. The semi-empirical compact models (such as compact model 1, also known as CM1) are generally used in the semiconductor industries for resist simulation since the physical models are computationally expensive. The CM1 model considers physical effects of the resist process and uses a constant threshold on a two dimensional resist surface to extract the critical dimension (CD). However, the required threshold for different samples may vary over a range and therefore a constant threshold value may not hit an optimal solution for all the samples. In this paper, we propose a clustering based approach to enhance the accuracy of CM1 model and resist simulation. In this proposed approach, various attributes of the lithographic samples such as aerial image and pattern density are used to bin the samples into different groups (clusters). The CM1 model is then used to calibrate parameters individually for each group. This approach is verified by doing the resist simulation on one of the layers of 14nm CMOS technology and the results show good improvement in model accuracy

No full textAtlikdama polichromijos tyrimus Lietuvos architektūros objektuose, susiduriu su visuomenei menkai žinomais, paveldo institucijų nelabai vertinamais, bet unikaliais pastatais ir dekoru. Net kartotinis straipsnis publikuotas žurnale „Kultūros barai“, 2020 m. Nr. 10 projektas gali Lietuvos kontekste sužibėti kaip išskirtinis epochos atspindys, kurį verta išsaugoti. Vienas iš tokių - Palangos kino teatras „Naglis“. Pastatytas 1959 m., niekada nebuvo rimčiau tvarkomas, renovuojamas. Išlaikė ne tik originalų suplanavimą ir dekorą, vestibiulyje išliko senoji grindų danga (teracas), sienų, lubų karnizai ir svarbiausias interjero akcentas - dekoratyvinis pano. Remiantis ikonografine medžiaga ir atlikus interjero polichromijos tyrimus, pavyko rasti ir nustatyti pirmąjį dekoravimo sluoksnį: sgrafito technika atliktą pano, kuriame vaizduojamos Neringos ir Naglio figūros, stilizuotos bangos, kūrinio centre - slibinas, trys buriniai žvejų laiveliai ir į dangų kylančios žuvėdros. Autorius - dailininkas Jonas Jukonis.The Author of the article is a restorer architect, an expert of tangible fixed cultural heritage, and a mural paintings conservator-restorer of the highest rank. This article presents the panel found in the cinema of the Palanga named “Naglis”. This panel was created by an artist Jonas Jukonis with the Sgraffito technique. This text describes other works of an artist Jonas Jukonis and the history of cinema in postwar Lithuania. It is also noticed that many examples of Lithuanian postwar cultural heritage (architectural as well as art) are not protected by the law and are already destroyed by new owners
