Authors: Türten Burak , Tayınmak İlknur
Published: October 2024

Belgesel film, sinema tarihi boyunca gerçekliği kendine özne edinen yapısı ile güçlü bir anlatım aracı olmuştur. Bu yönü ile belgesel filmler, izleyicilerin tutum ve davranışlarında etkili olabilmektedir. Bu çalışmada, tarihsel süreç içerisinde farklı gruplar tarafından kitleleri etkileme amacı ile kullanılan belgesel filmlerin, önyargılı tutumlar üzerindeki etkisini test etmek amaçlanmaktadır. Bu amaçla belediye çöplüklerinde çalışan insanların yaşamını konu alan Çöp belgesel filminin, çöplükte çalışan bireylere yönelik tutumları değiştirme gücü incelenmiştir. Mevcut araştırmanının örneklemini 103 üniversite öğrencisi ve personeli (yaş ort.= 22,43, SS= 6,39) oluşturmaktadır. Bu araştırmada Kişisel Bilgi Formu, Sosyal Mesafe Ölçeği, Empatik Eğilim Ölçeği ve Önyargısal Tutum Ölçeği’nden oluşan bir anket formu kullanılmıştır. Ek olarak katılımcıların, çöp toplayanlara yönelik kalıpyargılarını ve duygularını değerlendirmek amacıyla cümle tamamlama ifadeleri sunulmuştur. Bu araştırmada deney ve kontrol grubu katılımcılarından ön test ve son test aşaması kapsamında iki farklı zamanda ölçüm alınmıştır. Deney grubunda yer alan katılımcılar Çöp belgeselini izlerken, kontrol grubundaki katılımcılar Bademler belgesel filmini izlemiştir. Elde edilen verilerin analizi sonucunda, deney grubunda yer alan katılımcıların ön test ve son test pozitif duygu ve negatif duygu puanlarının beklenen yönde değiştiği belirlenmiştir. Deney grubu ve kontrol grubu katılımcılarının, sosyal mesafe düzeylerinde ise beklenenin tersi yönde anlamlı bir etki görülmüştür. Cümle tamamlamaya ilişkin yanıtlar incelendiğinde ise deney grubu katılımcılarının, kontrol grubuna kıyasla, çöplükte çalışanlara yönelik olumlu ifadelerinin arttığı tespit edilmiştir. Buna ek olarak, deney grubunda yer alan katılımcıların, belgeseli izledikten sonra çöplükte çalışanlara yönelik empatik ifadelerinin yoğun olduğu belirlenmiştir. Elde edilen bu bulgular, adil dünya inancı ve hazırlayıcı etki kavramları çerçevesinde tartışılmıştır. Bu araştırmanın, belgesel sinema ve önyargı konusundaki bilgi birikimine ve önyargıların azaltılması konusunda geliştirilecek programlara katkı sağlayacağı düşünülmektedir. Bunun yanı sıra araştırmanın, iletişim çalışmalarındaki etki alanlarının genişlemesi ve sinemanın toplumsal katkısının artması gibi durumlara temel oluşturacağı ön görülmektedir.
Aspectos teóricos e práticos da espectroscopia de emissão em chama
Authors: Andrade João Carlos de , Baccan Nivaldo
Published: October 2024

Quando excitados por uma fonte de energia externa, como uma chama, um arco elétrico ou uma faísca, os elétrons dos átomos em seus estados fundamentais são excitados para outros estados mais energéticos e, quando retornam aos seus estados de energia mais baixos, emitem fótons. O uso desse processo físico para fins analíticos quantitativos é conhecido como espectroscopia de emissão atômica e, se uma chama for usada como fonte de energia, é chamado de espectroscopia de emissão atômica de chama, ou simplesmente fotometria de chama. Os processos físicos envolvidos são muito rápidos porque os tempos de vida dos estados excitados são curtos. No entanto, eles ainda podem ser usados ​​em experimentos didáticos em laboratórios de ensino de Química Geral e Química Analítica. Atualmente equipamentos modernos de espectroscopia de emissão são amplamente utilizados em geoquímica e mineralogia, análise de água e minerais, análise de solo, planta e fertilizantes, bioquímica e medicina. Na indústria, é rotineiramente empregado para o controle de qualidade de reagentes e de outros produtos, como ligas metálicas, vidro, cimento e cerâmica. Neste artigo, as características, usos e limitações da espectroscopia de emissão atômica de chama como uma técnica analítica são apresentadas de forma simples e direta, e experimentos educacionais bem conhecidos são usados ​​para ilustrar a teoria. Ao longo do texto, algumas questões destacadas são apresentadas para encorajar o leitor a buscar respostas na literatura.

Efficient selective hydrogenation of phenylacetylene over Pd-based rare earth dual-atomic catalysts
Authors: Che Leisheng , Zhong Ziyun , Cui Peng , Du Yaping , Zhang Hongbo
Published: October 2024

Selective hydrogenation of phenylacetylene to styrene plays a vital role in fine chemical synthesis with palladium (Pd)-based catalysts as the active components and usually suffered from low selectivity due to over-hydrogenation and low stability through polymerization (c.a. green oil generation). In this work, we found that by confining the Pd atom within a Pd-Ln (Ln: rare earth elements, such as Y, Lu, etc. ) diatomic structure [diatomic catalyst (DAC)], the reaction performance of selective hydrogenation of phenylacetylene has been greatly promoted, in which 92% styrene selectivity has been determined at 100% phenylacetylene conversion. This would be attributed to the diatomic structure established, which was achieved by introducing Pd-Ln precursors and confirmed by high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) and X-ray adsorption fine structure (XAFS) characterizations and it was demonstrated that slight electron transfer from Ln to the adjacent isolated Pd makes it slightly negatively charged and facilitated the styrene formation. Besides, a Langmuir-Hinshelwood model was established to describe the whole reaction mechanism. After a systematic kinetic investigation, it suggests that the C8H6* + H* elementary step is probably the kinetically relevant for the whole reaction and the surface of the catalyst is mainly covered by C8H6*. The energy relationship of each step along phenylacetylene hydrogenation was quantitatively described by means of parity fitting and gas isothermal adsorption, providing insights into the selective hydrogenation of phenylacetylene over 0.02%Pd-Ln/C (Ln = Y/Lu) catalysts and pave the way of catalytic design at the atomic level.

War in foreign lands, hunger at home
Authors: Yingi Edwin
Published: October 2024

The war between Russia and Ukraine pitted two major agricultural countries and threatened the African continent with food insecurity and hunger. The war came at a time when the world was emerging from another global challenge of the COVID-19 pandemic and its attendant effects of distorted food prices and disruptions of the food supply chain. Informed by the analysis of the literature available on the Web of Science, Scopus, Google Scholar databases and grey literature from United Nations (UN) agencies, this study explores the challenges that emanated from the global problem of conflict and its implications on food security and the fight against hunger in Africa. The study found that the Russo-Ukrainian war exposed the lack of progress in Africa towards the fight to eliminate hunger. The consequences of the war have been aggravated by this lack of progress towards achieving zero hunger in many African countries. The war disrupted the global supply chain and threatened Africa with hunger as the continent experienced food shortages, food inflation and general commodity price volatility.
Engineering modelling requirements for integration of assistive technology as a pathway for inclusive education in the disability unit
Authors: Macheque Vhutshilo , Kadyamatimba Armstrong , Ochara Nixon
Published: October 2024

The phenomenon of 'massification in higher education ', which refers to the significant increase in the number of students enrolling in universities, has made it difficult for inclusive education to be attainable owing to unknown reasons that are encumbering the students living with disability from having a sense of belonging. Hence, this study aims to evaluate the relationship between students living with disability and social justice through inclusivity in higher education with the aid of Assistive Technology (AT) to conceptualise a framework. The researchers employed a mixed methods approach to collect and analyse data statistically and descriptively. The requirements for integrating the model to ease the lack of consideration of students living with disability in the digital age were evaluated and critically reviewed regarding its impact on students’ sense of belonging in the digital age. The major findings from this study elucidate the factors perceived as the central requirements for mitigating the lack of inclusivity and social justice in higher education. The procurement of ATs was topical as most respondents (83%) categorically opined the need to improve this process by making timely purchases of the proper ATs from reliable service providers.  The successful implementation of this framework could significantly enhance the educational experience of students with disabilities at the University of Venda, making it a more inclusive and supportive learning environment. The findings on the appropriateness of ATs for students overwhelmingly indicated that many of the available devices and technologies meant to assist learners were not fit for the tasks they were intended for. The university should establish a procurement committee and a high-level action plan outlining the requirements for delivering assistive products & services.

Published: October 2024

The South African construction sector is confronted by significant obstacles, particularly concerning cost overruns and project delays within the road construction sphere. This research sought to investigate the factors impacting cost and duration in road construction projects under the purview of a KwaZulu-Natal municipality. A qualitative research approach was adopted to explore this phenomenon. A sample size of 27 participants was selected from a population of 171 for in-depth semi-structured interviews. Critical determinants of cost overruns and delays were identified as ineffective communication, suboptimal procurement processes, deficient stakeholder management, and shortcomings in project execution and personnel capabilities. This study offers valuable insights into the relationship between cost, time, and the successful delivery of road projects within the local government context. By illuminating these factors, the research contributes to a deeper theoretical understanding, informs evidence-based policy development, and provides actionable recommendations for enhancing project management practices.
Exploring the influence of ‘Korean Wave’ on brand loyalty: The moderating role of product type
Authors: Lady Lady , Meilani Lara , Cuandra Fendy , Na Bai
Published: October 2024

The ‘Korean Wave’ has significantly impacted the global economy, especially in Indonesia. However, there is a gap in understanding how Korean celebrities, as brand ambassadors, influence local consumer behavior and purchase intentions. This study aims to clarify this impact using the theory of planned behavior (TPB) framework. The roles of brand attachment, brand love, and brand loyalty, moderated by product type, were examined with 194 survey respondents, and data was analyzed using SmartPLS software. Key findings indicate that brand personality significantly influences brand attachment. Customer brand engagement positively affects brand love. Brand attachment impacts both brand loyalty and brand love, while brand love strongly influences brand loyalty. Brand loyalty significantly affects purchase intentions, confirming that loyal customers are more likely to make repeat purchases. Product type only moderates the influence of brand attachment on brand loyalty, not the influence of brand love on brand loyalty. The implications for marketers are significant. Businesses should leverage Korean celebrities as brand ambassadors to enhance brand visibility and loyalty. Aligning brand personality with ambassadors can deepen consumer attachment. Creating engaging content and focusing on emotional branding can foster stronger connections. Tailoring marketing strategies to different product types and monitoring brand loyalty feedback can enhance market performance. Despite its contributions, the study acknowledges limitations, including potential demographic biases and the need for broader cultural and product category exploration in future research.

Published: October 2024

Energy management strategy (EMS) is a decision-making algorithm for effective power allocation between storage devices in a hybrid energy storage system (HESS). Source voltages, state-of-charge (SOC), terminal voltage of load, and rate of change of battery current must be considered while implementing EMS and hence they are termed as performance indicators. This paper presents the development of an EMS designed to manage the performance indicators of the sources and ensure efficient power distribution through a shared bus topology. A shared bus topology employs individual converters for each source, offering efficient control over these sources. Rule-based fuzzy logic control ensures efficient power distribution between batteries and ultracapacitors. Additionally, hardware has been developed to validate the power-allocation strategy and regulate the DC-link voltage in the Energy Management System (EMS). The dSPACE MicroLabBox is utilized for the implementation of real-time control strategies. A battery and an ultracapacitor bank are utilized in a Hybrid Energy Storage System. The simulation outcomes have been corroborated by experimental data, affirming the efficacy of the proposed energy management strategy.
Unveiling Complex Breakup Dynamics in the Transitional Regime of Entrapped Air within High-Density Media
Authors: Osama Muhammad
Published: October 2024

The dynamics of a quiescent finite-size air filament in a static liquid is investigated through axisymmetric numerical simulations. Due to surface tension, the two ends of the air filament retract and form bulges. We categorize the observed breakup behavior into four distinct regimes on a phase diagram, labeled I, II, III, and IV, each with its appropriate scaling. For Ohnesorge number, Oh ≤ Oh lim = 0.1, the mass of the detached bubble is approximately more than 2.1 times the size of the initial radius of the filament. Using this assumption, a first-order approximate mathematical model is reported for Oh ≤ Oh lim that shows if the aspect ratio (Γ) of the filament is greater than 11, the filament will always breakup. In the neck-reopening regime, the jump distance from the neck to the center of the filament exhibits an increasing trend with an increase in Γ and decreases when Oh is increased. For the same regime, a recirculating flow generated around the stagnation point at the center of the filament induces the reopening of the neck, ultimately resulting in a breakup at the center of the filament.

Published: October 2024

Grass pea (Lathyrus sativus L.) is a nutritious legume crop well-adapted to fragile agro-ecosystems that can survive under challenging climatic conditions. The cultivation of grass pea faces stigma primarily due to the presence of β-N-Oxalyl-l-α, β-diaminopropionic Acid (β-ODAP), which is associated with a risk of inducing neurolathyrism upon prolonged consumption of its grains as a staple diet. The grass pea improvement program of International Center for Agricultural Research in the Dry Areas (ICARDA) aims to reduce β-ODAP content to a safe level along with improving yield potential and nutritional quality of grass pea. In this study, 183 germplasm accessions representing 13 different Lathyrus species and 11 L. sativus breeding lines were evaluated for β-ODAP content based on Rao protocol and mineral concentration using ICP-OES. Significant variability was observed among the accessions for the studied traits. The results showed low β-ODAP content and high mineral concentration in 25 accessions of crop wild relatives (CWR) which included L. cicera, L. ochrus and L. cassius with one accession IG65277 of L. cassius, in addition to two lines IG117034 and ACC1335 of L. sativus having very low ODAP content. Furthermore, some accessions of L. pseudocicera, L. aphaca, L. cicera, L. marmoratus, L. gorgoni and L. tingitanus also showed low β-ODAP content. The results showed significant positive correlations between different trait combinations viz., K and P (r =0.193***), K and Fe (r =0.177***), Mn and Fe (r = 0.210***), Mn and Se (r = 0.137***), ODAP and Mg (r = 0.158**), and ODAP and Ca (r = 0.140**). L. cicera, L. ochrus, and L. cassius were identified as a great source for improving the mineral concentration and reducing ODAP content in the cultivated grass pea.

Authors: Hafil Ach. Shodiqil
Published: October 2024

Madurese people who are synonymous with hard character and tend to be rude, are also known to be very religious so not a few are active in a tariqa, among which the popular one is Tarekat Qadiriyah Naqsyabandiyah (TQN). This article aims to examine the meaning of anthropological symbols in the practices and meanings of Madurese people towards the teachings of TQN, as well as how its implications in the personality and life of the Madurese. The methodology used is descriptive qualitative using Clifford Geertz's symbolic anthropology theory. This article concludes that symbolically anthropological TQN has a religious symbol system manifested in hybrid dhikr, zikr jahr (vocalised) and zikr khafiy (hidden). It also shows the existence of Madurese as spiritual subjects who know actively. The implications of dhikr in the lives of TQN pilgrims can be empirical, mystical and meta-empirical. Therefore, it is not uncommon for them to have magical experiences due to the energy of the practised zikr.

Significance. To date, the need for blood donors in Russia is not fully satisfied, which actualizes the demand for new young donors. At the same time there is a lack of comprehensive research on motivation of young people to donate in our country. The purpose of the study was to explore motivation of young people to donate blood and to develop practical recommendations for involving young people in blood donation. Material and methods. All-Russian sociological research was conducted in July 2022 among young people aged 16-23. 1030 people were interviewed online. The sex and age distribution of the sample corresponds to the Rosstat data on the number of representatives of the target group. The “Brand Analytics” software product was used to upload posts from social media, with the help of which 64,083 publications were uploaded. Results. Only 18% of the surveyed young people have experience in blood donation, and every 10th was disappointed in it. Motivation of young people to donate blood at the level of declarations is mainly guided by humanistic motives, with monetary rewards ranking second. Every third responded that a lack of financial incentives would reduce their desire to be a donor. Notification that the donated blood has been given to another person is a key non-material incentive, influencing the desire to donate among young people. Monetary rewards and the opportunity to check health are key tangible incentives. Half of the young people surveyed noted the influence of their environment on their involvement in blood donation, and there is also a link between participation in charitable activities and donation. We see reference groups as an important source of young people's involvement in donation. The role of social media in involving young people in donation is significant. The analysis of social media messages shows that the following two topics dominate the information field of donation: humanistic motives and general medical discussions. Motives of urgency and danger contribute to initial reactions, but do not always result in reposts. Conclusion. The motivation of young people to donate blood generally corresponds to the motivations of donors of older groups, with humanistic and material motivation coexisting. The study offers a number of practical recommendations. Scope of application. The results can be used to develop information policy on youth motivation in order to involve and retain in blood donation.
THE SPATIAL LINKAGES BETWEEN INTERNATIONAL MIGRATION AND SECURITY: THE EMPIRICAL FINDINGS FROM TURKEY HOSTING MOST REFUGEE IN THE WORLD
Authors: Tabak Osman , Zorlu Merve , Çelik Necmettin , Kaya Ayten Ayşen
Published: October 2024

The increasing international migration in the world, especially due to the conflict, have potential negative impacts in immigrant countries. An increase in crime rates caused by unemployed immigrants who cannot meet their food and housing needs is one of them. Accordingly, the study investigates the effects of international immigrants, whose numbers reached about 3,9 million in Turkey, on violent and financial crime rates. The Spatial Error Panel Model with Fixed Effects covering Turkey’s 26 NUTS-II regions and 2016-2019 period indicate that there are positive and statistically significant relationships between immigrants and these crime rates. However, the negative impacts of international migration on security are mainly observed in financial crimes rather than violent crimes. Furthermore, the most important determinants of these crimes are high food and housing costs. And also, there is a negative relationship between uneducated employment and financial crimes rather than violent crimes. On the other hand, the findings indicate that regions have spatial dependency positively in terms of violent crimes. It means that as average violent crimes increase in the neighbors of a region, the violent crimes of that region also increase.
A novel approach for Plant disease Classification through Neural Network-Based Color Feature Analysis
Authors: KS Archana , S Arun
Published: October 2024

plant disease identification using machine vision, which is a challenge in terms of maximizing both the quality and quantity of plant growth. The infection makes plants susceptible to disease. This needs continuous monitoring by experts, which is prohibitively expensive in large farms, but in some instances, erroneous observations by farmers culminate in poor diagnoses. Consequently, we need a fast and accurate plant disease diagnosis predicted to increase the area under cultivation, eliminate heavy losses, and ensure high accuracy. The focus must be on identifying early symptoms of plant disease using computer vision. In order to solve this problem, deep learning can combine machine learning and pattern recognition, two hottest topics in this field. We propose a novel method to identify different plant diseases using deep convolutional neural networks (CNNs). In this study, we propose an image-based classification approach for rice plant diseases, focusing solely on color features. We investigated 12 distinct color spaces and derived 4 features from each color channel, resulting in a total of 48 features. The accuracy of this model is much higher than that of traditional machine learning models. Using the best-performing model, we achieved a classification accuracy of 96.03%. The simulation results show that the proposed method for identifying plant diseases is effective and feasible.

Disrupted cytokine networks and autoantibodies play an important role in the pathogenesis of systemic lupus erythematosus. However, conflicting reports and non-reproducibility have hindered progress regarding the translational potential of cytokines in SLE. This study attempts to address the existing knowledge gap using multiplex cytokine assay and machine learning. 67 SLE patients fulfilling SLICC criteria were recruited after informed consent, and circulating cytokines were measured by multiplex cytokine assay kit. We observed a positive association between actual disease activity scores (SLEDAI) and predicted scores from a partial least squares regression (PLSR) analysis of multivariate cytokine response data, with MIP-1α having a strong contribution towards disease activity. Our analysis also highlights increased IL-17 as a potential biomarker in nephritis and elevated MIP-1α as a signature of NPSLE. Using a k-Modes clustering algorithm to stratify patients based on patterns of co-occurrence of circulating autoantibodies, we identified 4 distinct clusters of patients. Our analysis revealed a striking difference in the distribution of lupus nephritis between the clusters, with all patients in cluster 3 presenting with nephritis with significantly low levels of housekeeping and homeostatic cytokines and the presence of anti-Ro antibodies, which is a novel observation. Thus, we demonstrate that cytokines can be a surrogate to predict disease activity and organ involvement in SLE. Moreover, we show the utility of unsupervised machine learning algorithms combining specific autoantibody and cytokine signatures to predict renal involvement in SLE.
TERT mutations in Malignant Melanoma-Survival Meta-Analysis
Authors: Hahn Hyung Jin , Kim Hyun Ji
Published: October 2024

It has long been speculated that the TERT promoter mutation is linked to poor patient survival in malignant melanoma. However, this notion is still in contention, as evidenced by conflicting study results. Therefore, the authors took on a quantitative synthesis in order to gain a better grasp of the role of TERT mutation in melanoma and to further assess the feasibility of taking advantage of the defect as a prospective target in molecular targeted therapy PubMed, EMBASE, Cochrane, MEDLINE, Google Scholar, and other databases were searched with keywords such as "malignant melanoma". "TERT promoter mutation", and "survival". Hazard ratios, in disease‑specific and overall survival, were calculated for each survival-determining variable. Overall, MM patients with mutated TERT promoters were roughly 60% more likely to experience death compared to non-mutated individuals (pooled HR = 1.64). In subgroup analysis, age did not play much role in survival, but male sex, ulceration, acrally located lesions, high Breslow thickness, presence of mitosis, and higher clinical stages were notable factors in poor prognosis. When the TERT promoter is mutated concurrently with other common mutations, such as B-raf, N-ras, and c-kit, the hazard of death is much greater (pooled HR = 2.75). In conclusion, targeting TERT mutation may be one of the missing puzzles for effective targeted therapy in MM, as it influences and interacts with other common mutations.

Methods
From January 2022 to December 2022, elderly individuals who underwent physical examinations at Qingling Community Health Service Center were selected. Based on inclusion and exclusion criteria, a total of 4865 participants were eligible. According to walking speed results, participants were divided into two groups: the qualified group (≤ 8 seconds) with 3889 people (73.8%) and the unqualified group (> 8 seconds) with 1276 people (26.2%). Additional information on the participants was obtained through the electronic information system. A comparison of relevant information between the two groups was conducted to summarize the influencing factors of walking speed, with P < 0.05 indicating statistical significance.
Results
Age, marital status, caregiving situation, weekly exercise routine, drinking habits, height, weight, BMI, blood urea nitrogen, low-density lipoprotein, Chinese visceral adiposity index, cardiometabolic index, and systemic immune-inflammation index are all risk factors for decreased walking speed. ROC curve analysis showed that the systemic immune-inflammation index had the best predictive efficiency.
Conclusion
Marital status, caregiving situation, weekly exercise routine, and drinking habits are all correlated with decreased walking speed. Age, weight, waist circumference, and the systemic immune-inflammation index (SII) are positively correlated with decreased walking speed. In contrast, height, BMI, blood urea nitrogen, LDL-C, Chinese visceral adiposity index (CVAI), and cardiometabolic index (CMI) are negatively correlated with decreased walking speed. Among these factors, SII has the strongest predictive efficiency for decreased walking speed.

A 4-year-old male axis deer (Axis axis) died after several weeks of progressive weight loss and severe respiratory distress. A field necropsy was performed, and lung tissue was submitted for histopathology. Microscopically, there was severe, subacute to chronic, diffuse, suppurative bronchopneumonia with multiple caseonecrotic foci and bronchiectasis. Immunohistochemical (IHC) analysis using polyclonal antibodies for Mycoplasma bovis revealed positive immunoreactivity. The histopathological, and IHC findings observed in this deer are remarkably similar to pulmonary mycoplasmosis of cattle. These findings represent the first report of M. bovis-associated pneumonia in the axis deer and suggest that deer develop pulmonary disease and lung lesions like mycoplasmosis in domestic cattle.

Background: Patients with essential thrombocythemia (ET) can develop systemic thrombotic and hemorrhagic vascular complications due to increased and dysfunctional platelets.
Case presentation: We encountered a 49-year-old Japanese woman with a history of essential ET, cerebral infarction, hypertension, and hyperlipidemia. She had been taking anagrelide (2.5 mg/day) and aspirin (100 mg/day) and had vomited at home. At the time of admission to our hospital she was in a deep stupor. Head computed tomography showed severe subarachnoid hemorrhage (SAH) at the interhemispheric fissure, hematoma at the corpus callosum, and intraventricular hemorrhages. Digital subtraction angiography demonstrated multiple dilated, stenotic, tortuous intracranial arteries, and a dissecting aneurysm at the right anterior cerebral artery (ACA). The dissecting aneurysm measured 7.7 × 15.5 mm and a bleb was observed. Our diagnosis was ruptured ACA dissecting aneurysm and diffuse intracranial arterial dolichoectasia (DIADE). We performed stent-assisted coil embolization of the aneurysm. She remained apathetic and manifested unilateral apraxia and alien limb syndrome due to a partial callosal disconnection. Two months thereafter her symptoms gradually improved, her consciousness level and limb function improved and her modified Rankin scale (mRS) score was 2. However, when we tapered her antiplatelet therapy she again developed an acute cerebral infarct.
Conclusions: This is the first presentation of a patient with ET complicated by DIADE, both of which can result in ischemic and hemorrhagic vascular complications including SAH. As antithrombotic therapy in patients with DIADE and ET may be associated with higher hemorrhage rates, its effects must be monitored carefully.

Purpose
We aimed to evaluate the utility of surveillance contrast-enhanced chest computed tomography (CT) in detecting second primary breast cancer among breast cancer survivors, focusing on imaging and clinicopathological features contributing to tumor visibility. Additionally, we sought to provide insights into which patient populations benefit from contrast-enhanced chest CT.
Methods
We retrospectively analyzed records of patients diagnosed with in-breast recurrence through biopsy during surveillance follow-up after curative breast cancer surgery between January 2016 and August 2022. Patients who underwent contrast-enhanced chest CT within 1 month of diagnosis were included. Two radiologists reviewed chest CT scans for breast cancer lesions by consensus, and their findings were validated by two other radiologists blinded to tumor locations. Statistical analyses were performed to evaluate associations among clinicopathological factors, image features, and visibility.
Results
Eighty-nine recurrent tumors in 85 patients were included. Of these, 58 recurrent tumors were identified by the unblinded radiologists. The blinded radiologists independently identified 50 and 56 recurrences, with substantial inter-observer agreement. The visible group had a higher rate of invasive ductal carcinoma (IDC) and larger tumor sizes than those of the non-visible group. Tumors in fatty backgrounds exhibited greater visibility on chest CT than those in glandular tissues. Logistic regression analysis revealed that mastectomy patients had significantly increased visibility of recurrent tumors on chest CT.
Conclusion
Contrast-enhanced chest CT is valuable for detecting recurrent breast cancer, especially in mastectomy patients. Tumors in fatty backgrounds, larger tumors, mass-type tumors, and IDC are better visible on chest CT.

Purpose
The aim of this study was to compare stem revision and ORIF for the treatment of Vancouver B2 periprosthetic fractures of the femur.
Methods
From June 2012 to May 2022, 56 consecutive patients were studied at our institution. Four patients were lost to follow-up, four had incomplete data. Thus, 48 cases were included in the analysis. The patients were divided into a stem revision group (SR, group 1 with 25 patients) and an open reduction and internal fixation group (ORIF, group 2 with 23 patients). The surgical complications, perioperative parameters, and 1-year mortality rates were assessed, the functional outcomes were assessed with the Harris Hip Score, and the radiographic outcomes were assessed in accordance with the Beals and Tower criteria.
Results
In group 1, the mean follow-up time was 41.2 months, 40% of patients experienced complications, the mean HHS was 75.27, and 92% of the patients had “excellent–good” radiographic outcomes. In group 2, 21.7% of patients experienced complications, the mean HHS was 73.56, and 91.3% of the patients had “excellent–good” radiographic outcomes. The total number of postoperative complications, dislocation rate, blood loss volume, operation time and transfusion rate were lower in group 1 (ORIF), and two patients in group 2 (SR) experienced hip dislocation. There were no significant differences in the 1-year mortality rate, bone healing time or reoperation rate between the two groups. However, the time to total weight-bearing in the SR group was shorter than that in the ORIF group, and the radio subsidence rate in the SR group was lower than that in the ORIF group, especially for patients with poor compliance. The postoperative quality of life of the patients in the two groups was worse than their original quality of life before fracture.
Conclusions
Stem revision and ORIF are effective treatments for Vancouver B2 fractures. However, ORIF can be an option for elderly patients with several medical disorders, while stem revision is advantageous in terms of earlier weight bearing.

Pixelated approaches to wavefront sensing and generation are commonplace, but inefficient and present core challenges for development of effective phase array antenna due to the physical limitation in grating coupler placement and 2D Nyquist sampling limits. A major challenge in the use of pixelated PICs for free-space applications is that arrays of grating couplers commonly have low fill factor due to manufacturing constraints and waveguide cross-coupling, that lead to significant loss of power to grating lobes. We present a new programmable approach for free-space optical mode sorting that combines a re-configurable photonic integrated circuit (PIC) with a passive Optical Mode Selective Interface (OMSI) that eliminates grating lobes and fill factor losses. This approach can reduce the number of required on-chip optical inputs by a factor of more than 4, and sort spatial modes in four different orthogonal mode groups with a mean inter-channel cross-talk for sorting of approximately 22dB without any change to the physical optical system. This approach could alleviate many of the issues related to scaling of PIC technologies, reducing both optical losses and complexity for future systems that incorporate PIC devices.
