Transmission characteristics of linearly polarized light in altostratus help explain “UV-sky-pol” paradox
Authors: Xiangwei Zeng  , Yan Zhang  , Xueye Chen  , Xindong Sun
Published: September 2024

The perception of skylight polarization in the ultraviolet (UV) by some species is surprising, because the degree of polarization (DoP) of light from the clear sky is considerably lower in the UV than in the visible spectral range. This is the so-called “ultraviolet paradox of the perception of skylight polarization (UV-sky-pol paradox)”. To explain the “UV-sky-pol” paradox, we analyzed the polarization retention characteristics of parallel polarized light transmits in altostratus at multiple wavelengths. According to the polarization sensitive bands of flies, honeybee, scarab beetles and spider, the study wavelength was set at 350 nm, and the wavelength of control group was set at 400, 450, 500, 550 and 600 nm, respectively. Then, we used the polarized light Monte Carlo method to simulate the forward transmission of 100 000 parallel polarization photons in altostratus. Calculation results show that the polarization retention characteristics are excellent at the 350 nm wavelength. Finally, we analyzed the transmission characteristics of parallel polarized light passes through a droplet at 0°–15° forward scattering angle. The analysis results show that there have been significant polarization retention channels in the UV band around 350 nm. This study can help to elucidate the “UV-sky-pol” paradox.
EDFA based adaptive RZ-OOK transmission for FSO communication
Authors: Peng-Fei Lv  , Yan-Qing Hong
Published: September 2024

This paper proposes an erbium-doped fiber amplifier (EDFA) based adaptive return-to-zero on-off keying (RZ-OOK) transmission for free-space optical (FSO) communication. EDFA has the characteristics of average power limitation. Therefore, the transmitted RZ-OOK duty cycle is varied for accomplishing pulse power variations relying on determined average signal-to-noise ratio of received signal. Thus, the atmospheric turbulent effects can be compensated by this type of adaptive RZ-OOK transmission. The channel models with different turbulence effects are established, and the proposed technique is validated in simulation. The simulation results illustrate that the communication quality of system is considerably enhanced by the proposed technique compared with fixed threshold decision and adaptive threshold decision.
Cantilever-based biaxial FBG inclinometer with low cross-axis sensitivity
Authors: Ramalingam Nimalrajh , Hangting Yang  , Kok-Sing Lim  , Ahmad Harith
Published: September 2024

This work proposes and demonstrates a biaxial sensing inclinometer based on two FBGs surface-mounted on two separate thin cantilevers with a diminishable cross-axis sensitivity. The measured sensitivities for the inclination angles in the x-z plane and y-z plane are 34.87 and 33.49 pm/deg, respectively. To enhance the protection of the delicate FBGs and minimize axis-to-axis cross-sensitivity, the carbon-steel cantilevers are strategically arranged in a perpendicular configuration, resulting in an impressively low cross-sensitivity value of just 0.9275%. This alignment not only offers mechanical shielding but also ensures optimal performance and accuracy for the FBGs.
An ultra-wideband plasmonic reflector based on local resonant bandgap and Bragg bandgap
Authors: San Chen  , Liang Fang  , Jianqiang Liu  , Shan Wu
Published: September 2024

Unlike previous reports that utilized periodic modulation of insulation layer thickness or dielectrics, we propose the use of split ring resonators (SRRs) and their arrays to modulate the propagation characteristics of MIM plasmon waveguides. Due to the strong resonance backscattering of SRR, resonance transmission valleys appear in the transmission spectra of MIM waveguides. Changing the size of SRR can achieve continuously adjustable positions of resonance transmission valleys. The introduction of SRRs periodic arrays will result in two bands (bandgaps) with transmission minimum in the transmission spectra. Combining the dependence of the two bandgaps on the array period and the field distribution, the two bandgaps are Bragg bandgaps and local resonance bandgaps, respectively. By modulating the local resonance bandgap, the Bragg bandgap can be tuned. The introduction of local bandgap increases the degree of freedom to modulate the transmission characteristics of MIM waveguides. Combining local resonant bandgap and Bragg bandgap can significantly increase the reflection bandwidth, achieve broadband filtering, and facilitate the miniaturization of waveguide devices.

Authors: Seçkin Tuğçe , Kuş Beyza
Published: September 2024

Bitkiler antimikrobiyal ve antioksidan özelliklerinden dolayı yüzyıllardır birçok hastalığın tedavisinde kullanılan temel kaynaklar olmuşlardır. Özellikle geleneksel tıpta yaraları iyileştirici ve enfeksiyon giderici etkilerinden dolayı kullanımları yaygındır. Son yıllarda antibiyotiklerin bağırsak mikrobiyotası üzerindeki yan etkileri ve mikroorganizmaların antibiyotiklere karşı oluşturdukları direnç sebebiyle de araştırmalarda bitkilerin kullanımı ön plana çıkmaktadır. Bu çalışmada İzmir bölgesinden toplanan Plantago lanceolata (P. lanceolata) bitkisinin antibakteriyel ve antifungal aktivitesi incelendi. Bitki yaprağından metanol, etil asetat ve n-hekzan ekstraktı olmak üzere 3 farklı ekstrakt elde edildi. Farklı konsantrasyonlardaki bitki ekstraktlarının antimikrobiyal aktivitesi, patojen mikroorganizmalar Candida albicans, Enterococcus faecium, Escherichia coli, Proteus mirabilis, Pseudemonas aeruginosa ve Staphylococcus aureus üzerinde disk difüzyon yöntemi kullanılarak incelendi. Elde edilen bulgulara göre bitkinin metanol ve etil asetat ekstraktına karşı en duyarlı bakterinin 28mm ve 23mm inhibisyon zonu ile E. faecium olduğu sonrasında sırasıyla S. aureus, P. mirabilis P. aeruginosa ve E.coli’ e karşı farklı düzeylerde zon çapı oluşturduğu C. albicans’a karşı ise inhibisyon zonu oluşturmadığı belirlendi. Hiçbir mikroorganizmanın n-hekzan ekstraktına karşı antimikrobiyal aktivite göstermediği tespit edildi. Ayrıca P.lanceolata’ a ait hiçbir ekstrakt bağırsak mikrobiyatasında yer alan probiyotik özellikteki Lactobacillius plantarum üzerinde inhibisyon zonu oluşturmadı. Sonuç olarak, bu çalışmadan elde edilen verilerden yola çıkılarak İzmir bölgesinde yetişen P. lanceolata’nın mikrobiyota dengesine zarar vermeden gram (+) ve gram (-) bakterilere karşı önemli bir antimikrobiyal potansiyele sahip olduğu söylenebilir. Elde edilen bu sonuçların ileri çalışmalar için temel oluşturması beklenmektedir.

The presence of spiritual and religious landmarks significantly benefits the tourism industry. Jamek Mosque in Kuala Lumpur, Malaysia, is a culturally rich iconic mosque established in 1909, serving both as a place of worship and a tourist attraction. However, it is unclear if its location in the bustling city environment supports positive user experience despite officer surveillance and facilities. The study employs qualitative methodologies to evaluate the experiences of individuals in the vicinity of the historic mosque. Semi-structured interviews and structured observations of user activities were conducted. Interviews used prompt guides and video recordings to understand the mosque site officers' and users' perspectives. Structured observations were conducted using the 'Path-Portal-Place' concept, with twelve hours of on-site observation and five potential users interviewed.  Data analysis involved transcribing field notes and audio recordings into protocols and transcripts, followed by coding and expert verification. Interviews revealed 40 sub-themes under path-portal-place activity, path-portal-place experience, and path-portal-place experience. The primary activities observed within the domain of path-portal-place experiences include walking, taking self-photos, sitting, relaxing, standing, and resting. Users frequently express that the ambiance of the place is remarkably peaceful, and they deem the historical significance of the location as the key factor making it worthwhile to visit. Recommendations include maintaining functional and heritage preservation aspects to ensures that the mosque becomes a multifunctional and culturally significant space that respects its heritage to serves as a supportive spiritual tourism destination.

Integrating Scientific and Everyday Concepts: Student Leadership in a Language Learning Community
Authors: Hooper Daniel
Published: September 2024

This study examines the role of everyday and scientific concepts in developing student leadership in a self-access learning center (SALC) in Japan. For this purpose, data from three student learning community leaders and one SALC faculty member participating in an 18-month ethnographic case study of the Learning Group (LG), a student-led learning community within a university-based SALC in central Japan, was reexamined according to a framework informed by concept-based learning. Data was first coded inductively utilizing reflective thematic analysis (Braun & Clarke, 2006) and subsequently deductively using communities of practice theory and the themes of scientific and everyday knowledge. This data highlights numerous ways three leaders of the LG had internalized concepts introduced to them through a SALC-based leadership course administered by a learning advisor (LA) and how this influenced not only their individual learning trajectories, but also the path of their community. Furthermore, the LG leaders were able to develop coherent management/facilitation guidelines for themselves and for future generations of leaders from the social mediation that collaborative group reflection and intentional reflective dialogue afforded. The implications of this study highlight the potential value within SALCs of learning advisors engaging in concept-based instructional approaches where explicit instruction is internalized through dialogic and communicative verbalization and through finding avenues for learners to apply scientific concepts to everyday practice.
Tales of Online Learner Autonomy: Highlights and Challenges in the Disruptive Age
Authors: Olobia Leoncio P.
Published: September 2024

When the new normal learning mode capitalized on technologically mediated communication, it created a high learner-content interaction while honing critical thinking and collaborative skills to achieve optimal learning. The disruption brought about by the Covid-19 pandemic instilled a sense of independence and flexibility in learning. The aim of this autoethnography is to consider the accounts of the author’s independent learning throughout the pandemic in an online course. The author’s comments, insights, and observations, which formed dense descriptions of the lived realities and were interpreted and analyzed through an autoethnographic lens, constituted a significant portion of the data. The findings show that students who engage in online learner autonomy assume complete accountability and exercise control over the learning process, thereby strengthening their capacity for independent and cooperative learning. Students face difficulties when they are overly flexible and independent, which leads to uncritical assessment of the material covered. The problem can be solved by applying critical thinking.
Approximate and Exact Solutions of Some Nonlinear Differential Equations Using the Novel Coupling Approach in the Sense of Conformable Fractional Derivative
Authors: Liaqat Muhammad Imran , Akgül Ali
Published: September 2024

Several scientific fields utilize fractional nonlinear partial differential equations to model various phenomena. However, most of these equations lack exact solutions. Consequently, techniques for obtaining approximate solutions, which sometimes yield exact solutions, are essential. In this research, we develop a new approach by combining the homotopy perturbation method (HPM) and the conformable natural transform to solve the gas-dynamic equation (GDE), the Fokker-Planck equation (FPE), and the Swift-Hohenberg equation (SHE) in the context of conformable derivatives. The proposed approach is called the conformable natural homotopy perturbation method (CNHPM). This approach has the advantage of not requiring assumptions about significant or minor physical factors. Consequently, it eliminates some of the constraints associated with conventional perturbation methods and can solve both weak and highly nonlinear problems. We consider the absolute, relative, and residual errors numerically and graphically to assess the correctness of our approach. The results show that our approach serves as a suitable alternative to the approximate methods in the literature for solving fractional differential equations.

Além do modelo tradicional: a resistência do patriarcado no reconhecimento das famílias paralelas
Authors: Nunes Souza Bárbara Aparecida
Published: September 2024

A evolução da concepção de família está intrinsecamente vinculada às transformações culturais e sociais, especialmente refletida na legislação brasileira desde a promulgação da Constituição de 1988, onde o princípio da dignidade da pessoa humana tornou-se central. No entanto, apesar do reconhecimento da crescente diversidade familiar, incluindo arranjos simultâneos ou paralelos, a estrutura patriarcal ainda exerce influência, muitas vezes implícita, nas decisões judiciais, moldando normas e expectativas. A pesquisa objetiva analisar, sob uma perspectiva de gênero, como o patriarcado influencia o não reconhecimento das famílias paralelas. Inicialmente, será examinada a relação histórica entre o patriarcado e a monogamia. Em seguida, serão identificadas as características das famílias paralelas, bem como as normas legais pertinentes à união estável e o entendimento dos Tribunais Superiores sobre o tema. Posteriormente, serão discutidos os desafios da imparcialidade judicial em um contexto social marcado por vieses patriarcais. Por fim, serão apresentadas as conclusões decorrentes da pesquisa. Utilizando o método dedutivo e análise bibliográfica e jurisprudencial, esta pesquisa busca contribuir para uma compreensão mais ampla das dinâmicas de resistência do patriarcado no sistema jurídico brasileiro, promovendo uma abordagem mais inclusiva e igualitária em relação às famílias simultâneas.

Introducción
Los medios de comunicación son claves en la configuración de la imagen social de las enfermeras. La difusión de una imagen de enfermería incoherente con su identidad profesional tiene consecuencias adversas para las enfermeras, para el conjunto del sistema sanitario y para la sociedad.
Objetivo
Comparar la imagen de las enfermeras y su papel como fuentes informativas en 2019-2020 tomando como marco para el análisis la identidad profesional consensuada por ISPIN. Estudiar si durante la pandemia COVID-19 la imagen de las enfermeras en los medios fue más completa y si se les dio mayor protagonismo como fuentes informativas.
Metodología
Análisis cuantitativo con un instrumento que evalúa la coherencia entre la imagen publicada y la identidad profesional enfermera definida por ISPIN en las 468 noticias publicadas en El País y El Mundo en 2019-2020, que incluían la palabra enfermera/s, enfermeros/s o enfermería.
Resultados
La presencia mediática de las enfermeras aumentó en 2020. Las temáticas principales en las que se las mencionó durante los dos años estuvieron relacionadas con cuestiones problemáticas del ejercicio de la profesión. El número de informaciones publicadas en las que se describe su trabajo diario aumentó en 2020. El rol más difundido siguió siendo el asistencial, pero la visibilidad de su función como gestoras aumentó notablemente durante la pandemia. Los estereotipos para representarlas se redujeron y la presencia de hombres enfermeros aumentó. Aunque se incrementó la presencia de las enfermeras y de sus asociaciones como fuentes informativas, no fueron fuentes principales en la mayoría de las noticias.
Discourse on Consumer Legal Protection on The Inclusion of Exoneration Clauses (Standardised Contract) In An Agreement
Authors: Tunggati Melki T. , Ibrahim Arif M. , Moha Sri Wahyuni S.
Published: September 2024

The purpose of this study is to find out whether the standard agreement reflects the principle of freedom of contract in an agreement and the form of legal protection against the inclusion of the standard clause in an agreement. The results of this study indicate that the application of the standard clause in an agreement does not reflect and does not realize the principle of full freedom of contract, because the consumer has only the freedom to decide whether he makes a contract or not and the freedom to vote with whom he will make the agreement. While the debtor has absolutely no freedom to make agreements on the substance of the treaty, the contents of the agreement, the form of agreement and the manner of making the agreement and the protection of the law in the inclusion of the standard clause is set forth in article 18 of the consumer protection legislation regarding the ban on the inclusion of the standard clause. However, if in the implementation of the standard agreement there is a difference of interpretation of the standard contract formulation made by the parties then one of the legal efforts that can be done to become a defense fortress or legal protection to the consumer so that in the implementation of the standard agreement does not incriminate one party in contract, especially the consumer Then the standard contract formulation shall use the interpretation of an impartial agreement to the standard contractor.

Realizing active targeting in cancer nanomedicine with ultrasmall nanoparticles
Authors: Lima André F , Justo Giselle Z , Sousa Alioscka A
Published: September 2024

Ultrasmall nanoparticles (usNPs) have emerged as promising theranostic tools in cancer nanomedicine. With sizes comparable to globular proteins, usNPs exhibit unique physicochemical properties and physiological behavior distinct from larger particles, including lack of protein corona formation, efficient renal clearance, and reduced recognition and sequestration by the reticuloendothelial system. In cancer treatment, usNPs demonstrate favorable tumor penetration and intratumoral diffusion. Active targeting strategies, incorporating ligands for specific tumor receptor binding, serve to further enhance usNP tumor selectivity and therapeutic performance. Numerous preclinical studies have already demonstrated the potential of actively targeted usNPs, revealing increased tumor accumulation and retention compared to non-targeted counterparts. In this review, we explore actively targeted inorganic usNPs, highlighting their biological properties and behavior, along with applications in both preclinical and clinical settings.

Authors: Butt Smaher E , Kepski Konrad , Sotiropoulos Jean-Marc , Moran Wesley J
Published: September 2024

A change in mechanism was observed in the hypervalent iodine-mediated cyclization of N-alkenylamides when the carbon chain between the alkene and the amide increased from two to three atoms. In the latter case, cyclization at the amide nitrogen to form the pyrrolidine ring was favored over cyclization at the amide oxygen. A DFT study was undertaken to rationalize the change in mechanism of this cyclization process. In addition, reaction conditions were developed, and the scope of this cyclization studied.

Concluyendo que, pese a la débil cultura organizacional encontrada, el compromiso organizacional de los trabajadores es alto, esto se mantiene gracias a factores económicos como utilidades y bonos de productividad, además de las facilidades como permisos de estudio y horarios estables.

La investigación tuvo como objetivo identificar árboles semilleros de Myrsine oligophylla Zahlbr, aplicando criterios de selección, en poblaciones naturales de los caseríos de Quilagán y El Guayo, distrito de Querocotillo, provincia de Cutervo, departamento Cajamarca, Perú. En los últimos años el ecosistema se ha visto afectado por intervención antrópica, especialmente agricultura migratoria, sobrepastoreo e incendios. Se busca con este estudio caracterizar árboles con buenas características morfológicas que permitan disponer de semillas para futuros trabajos de propagación y conservación en un banco de semillas, para ello se utilizó el método de valoración individual, valorizando las características fenotípicas y dasométricas (DAP (Diámetro a la altura del pecho) y HT (Altura Total)) de los árboles semilleros. Se identificaron 12 árboles semilleros en el caserío Quilagán y 15 árboles semilleros en el caserío El Guayo y se elaboró un mapa de distribución de los árboles semilleros Myrsine oligophylla Zahlbr. Los 27 árboles cumplen con características sobresalientes para ser considerados árboles padres o semilleros.

La investigación evaluó el desempeño sísmico del edificio de la Universidad Alas Peruanas, Jaén, Perú, conformado por dos módulos y una escalera. Empleando la Norma VISION2000, se determinaron los niveles de peligrosidad sísmica, se incorporaron patrones de cargas para obtener la curva de capacidad bilineal y mediante el método de los coeficientes modificados se obtuvo el nivel de desempeño. El modelado 3D se realizó con el software Etabs v.18.1.0 versión académica. Según la Norma ASCE 41-17, la evaluación incluyó el nivel 1 que comprendió una inspección in – situ para el llenado de listas de verificación rápida en los componentes estructurales y no estructurales. Y, el nivel 3 que comprendió un análisis estático no lineal – pushover, considerando los niveles de peligrosidad sísmica e incorporándose un patrón de carga de distribución vertical proporcional a valores de Cvx. A través de una curva bilineal y por el método de los coeficientes modificados se obtuvo el desplazamiento objetivo y junto con la Norma VISION2000, ambos módulos mostraron un nivel desempeño sísmico de colapso, es decir; no presenta una adecuada capacidad para soportar deformaciones inelásticas. Por lo tanto, requieren reforzamiento estructural para mejorar su resistencia ante eventos sísmicos.

Background and objectives. Sudden cardiac deaths (SCDs) have a significant impact worldwide. Its distribution trends may vary across different communities globally. Consequently, investigating sudden cardiac deaths necessitates a regional, multi-faceted approach. This study aims to ascertain the pathological background of the patients who died in the context of sudden cardiac death and analyze it statistically to generate some trends and define the occurrence of disease. Materials and methods. We conducted a retrospective analysis of the causes of death for cases from the Legal-Medicine Department of Maramures County, Romania, between 2021 and 2023. From this cohort, we identified and selected cases of SCD and conducted a statistical analysis of the number of cases, gender distribution, age group distribution, and the underlying cardiac pathology that led to this outcome. Results. 276 sudden cardiac deaths (SCD) were identified from 1,186 autopsies. Males accounted for 75% of SCD cases, with a mean age of 58.8 years. Advanced myocardial fibrosis (41.6%) was the most frequent cause, followed by coronary artery disease (18.12%) and acute myocardial infarction (17.4%). Males had significantly more AMI cases (p = 0.045), while females had more coronary artery disease and advanced myocardial fibrosis, though not statistically significant. Conclusions. Sudden cardiac death predominantly affects males, particularly those aged 51–60, with advanced myocardial fibrosis being the most common cause. The gender difference in AMI prevalence was significant, highlighting the need for targeted prevention and diagnostic improvements. Further research in liaison with experts in all fields is required.
