Telling Time: A Rhetorical Approach to Narrative Order
Authors: Bancroft Corinne
Published: December 2024

Critics of Nicole Krauss's Great House (2010) find the novel “downbeat,” “tragic,” and “bleak.” Such interpretations rely on what Peter J. Rabinowitz has called “the rule of conclusive endings” by privileging the narrator of the final chapter. However, as a braided narrative, Great House weaves together five characters who narrate different stories that lead to more hopeful interpretations. The following article proposes that Krauss invites readers to simultaneously privilege multiple, conflicting interpretations by emphasizing the occasions on which her character-narrators speak. Although occasion is the central term in the rhetorical definition of narrative according to James Phelan and Rabinowitz, it has not received as much theoretical attention as the other components. Each narrator's occasion has clear temporal dimensions that cannot be reduced to one side of the story/discourse binary. Although many postclassical schools of narratology have moved away from the story/discourse distinction as central to the definition of narrative, theorists still use this binary when describing narrative order. This pair of terms fails to capture a crucial dimension of narrative time: telling time, the story moments from which a narrator speaks that contain every word of their text. While the Great House's text order ending leads to a depressing conclusion, the novel's telling order and simultaneous telling times illuminate more optimistic interpretations. Attending to the dimension of telling time in Great House illuminates an intersubjective field that not only makes the novel's tragic themes bearable but also imbues the novel with a sense of vitality and hope.
Bireysel Dindarlığın Ontolojisi: Modernlik Ufkunda Statik Dindarlık Anlayışının Eleştirel Bir Değerlendirmesi
Authors: Dedemoğlu Gonca
Published: December 2024

Modernliğin insanlık-kutsal ilişkisinin vasfını sekülerleştirdiği yahut yeni dindarlık biçimlerinin nedeni olduğu söylemleri, dindarlığın ontolojisini örten yaklaşımlardır. Bu yöndeki argümanlar, nihayetinde modernliğin normatif-epistemolojik kategorizasyonunu esas alan ve tekil din-tekil modernleşme karşıtlığına uzanan bir dindarlık fikrine dayanmaktadırlar. Buradaki sorun, dindarlığı sabit bir forma indirgeyip müntesiplerinin kendi inanç, tutum ve eylemlerini niçin ve nasıl benimsediklerinden yalıtılmış bir dinin, araştırma nesnesi olarak ele alınmasıdır. Nitekim bireysel dindarlık kuramları, birçok halde iktisadi akılcılık ilkesine ve/veya bireye dışsal etkenlere isnatla fakat birey nezdinde dindarlığın nasıl kurulduğunu göz ardı ederek bireysel dindarlığı anlama ve açıklamaya yönelmektedir. Bu minvalde bu çalışmada, modernlik-dindarlık ikiliğine atıfla ulaşılan sonuçların dindarlığın serüveni hakkında nedensel bir şey söylemediği gibi ontolojisini de örtük kıldığı iddia edilmekte ve buradan hareketle bir sınama alanı olarak bireysel dindarlık teorileri ile olgusal gerçeklik arasındaki mesafeyi müzakereye açmaya hakemlik edebilecek ampirik bir araştırmanın kılavuz sorularının neler olabileceği ve bunların gerekçeleri tartışılmaktadır. Bu amaçla tasarlanacak bir araştırmanın, faillerin dindarlıklarını nasıl anlamlandırdıkları, inşa ve icra süreçlerindeki süreklilik ve kopuşlar ile bunların gerekçelerini tespit etmeye yönelmesi nedeniyle niteliksel olması ve amaçlı örneklem tekniğiyle yürütülmesi önerilmektedir.
Kentsel Dönüşümü Duygular Üzerinden Yeniden Düşünmek: Diyarbakır Suriçi Örneği
Authors: Gürhan Nazife
Published: December 2024

Kentsel dönüşüm; mekansal, ekonomik ve sosyal değişimlerden ötürü sakinlerine kaliteli yaşam alanları sunamayan bölgelerin yaşam kalitesini artırmak ve sosyal hizmetlere ulaşımı sağlamak amacıyla belirlenen yere müdahale edilerek bölgenin dönüştürülmesidir. Kentsel mekanı değiştirip dönüştüren kentsel dönüşüm uygulamaları mekansal, toplumsal, kültürel, ekonomik ve duygusal sonuçlar ortaya çıkarmaktadır. Bu çalışma, Diyarbakır’ın Suriçi bölgesinde 2016 sonrasında uygulanan kentsel dönüşüm projesinin mekansal sonuçlarının ortaya çıkardığı duygusal boyutları ele almaktadır. Çalışmanın amacı, Diyarbakır Suriçi örneğinde kentsel dönüşüm sürecini duygular üzerinden yeniden düşünmek ve bu süreci anlamaya çalışmaktır. Çalışmada nitel araştırma yöntemlerinden fenomenolojik desen kullanılmıştır. Veri toplama tekniği ise derinlemesine görüşmedir. Örneklemi ise Diyarbakır’ın Suriçi bölgesinde ikamet ederken 2015 yılında bölgede gerçekleşen terör eylemleri ve çatışma süreci sonrasında bölgeyi terk etmek zorunda kalmış ve mahalleleri kentsel dönüşüme uğramış 23 ile 60 yaş arası farklı yaşta 8 kadın ve 4 erkekten oluşan toplam 12 kişidir. Çaresizlik, üzüntü, mutsuzluk, kaybetme ve geçmişe özlem duyguları, çalışmada öne çıkan temalardır.
Neokolonyal Hafıza İnşası ve Abd el-Kader Müzeciliği
Authors: Karaarslan Faruk , Topal Said
Published: December 2024

Hafıza inşası, kolonyal süreçlerin ve yeni kolonyal formların işleyişinin ayrılmaz bir parçasını teşkil eder. Mekanın, ritüelin, bedensel pratiklerin ve tarih anlatısının şekillendirilmesi suretiyle, kolonyal toplumların kolektif hafızasını biçimlendirmeye devam eder. Bu noktada, sosyal bilimlerin iki farklı alanı; hafıza inşası ve neokolonyalizm ilişkisi, yeni bir tartışma alanı açmaktadır. Bu ilişki, çalışmamız bağlamında karşılığını, neokolonyal hafıza kavramsallaştırmasında bulmaktadır. Bu çalışmanın konusunu, Fransa ve Cezayir’in ortak kolonyal dönem tarihinin ve direnişin sembol şahsiyetinin konu edildiği Abd el-Kader müze sergisi oluşturmaktadır. 2022 yılında Fransa’nın Marsilya şehrinde, Avrupa ve Akdeniz Medeniyetler Müzesi’nde düzenlenen Abd el-Kader Sergisi, çalışmanın katılımcı gözlem ile gerçekleştirilen sahasını oluşturmaktadır. Çalışmanın amacı, Abd el-Kader müze sergisi üzerinden okuyarak, başta dönemselleştirme olmak üzere tarih yazımı, anlatı inşası, seçici hatırlatma ve unutturma gibi çarpıtma dinamiklerini içeren hafıza inşasının neokolonyal süreçler ile ilişkisine dair bir tartışma yürütmektir. Bu bağlamda, neokolonyal hafıza inşasının, bir taraftan kolonyal dönemin sorunlu geçmişini yatıştırma çabalarının bir parçası, diğer taraftan kolonyal mirasın ve güç eşitsizliklerinin sürdürülmesini içeren kültürel etki mekanizmasının aracı olduğu iddia edilmektedir. Abd el-Kader’in hayat serüvenini; direniş, tutsaklık, sürgün ve mirası olarak dönemselleştiren sergi, onun monografisini mağlup, tutsak, pasif; aynı zamanda lider, uyumlu, barış insanı, din adamı olarak sunmaktadır.
Adopting Social Justice as Nothing More than an Academic Jargon: Conceptualisation of Social Justice in Social Work and Social Policy Disciplines
Authors: Arun M. Onur , Özdemir Caner
Published: December 2024

A just society is not one where everyone is absolutely equal on all terms, nor scholarly literature on social justice is constrained by such a conception of the just. As observed from the broad scholarly literature of social justice, most theories in this field are competing and contending normative political perspectives informed by a sociological conception of inequalities and aiming to identify social, economic as well as institutional conditions under which resulting inequalities are morally necessary and desired, rather than proposing absolute equality. This work primarily aims to explore to what extent this foundational quality of social justice theories is adopted by peer-reviewed scholarly articles published in Türkiye within disciplines of social work and social policy whose identifying characteristic is to serve the establishment of the just society. Departing from this purpose, it methodologically employed a double-layered systematic literature review (n=184) and qualitative content analysis (n=62) to critically scrutinise peer-reviewed journal articles involving the concept of social justice. In addition to some complementary findings, these analyses resulted in three major findings based on which we argue that social justice in Türkiye is (1) primarily addressed as a part of the popular academic jargon along with some generic concepts such as human rights and welfare; (2) interchangeably used with the concept of equality although there are substantial distinctions between them; and (3) stressed in a way that there is a unified/homogenous conception of the just society that overlooks competing and contending normative perspectives in the relevant literature.

Published: December 2024

Background This study investigates the incidence and predictive factors of Hyperventilation Syndrome (HVS) in patients after COVID 19 pneumonia, addressing the clinical overlap between these conditions. Methods A one-month prospective study was conducted, tracking survivors of COVID-19 pneumonia. Patients were evaluated for ongoing clinical status, including HVS and post-traumatic syndrome disorder (PTSD), using clinical questionnaires, mMRC, Post-COVID-19 Functional Status (PCFS) Score, Nijmegen score, and PTSD Checklist for DSM-5 questionnaire. Results Our study included 222 patients (median age: 57 years, male predominance 62.6%). Somatic comorbidities, primarily metabolic disorders, were reported in 71.2% of cases. The majority had severe or critical infection forms (78.4%), and 91.9% experienced acute symptoms, with 86.5% having three or more symptom clusters. At one month follow-up, dyspnea (52.9%) and asthenia (21.7%) persisted. Functional limitations (PCFS Grade > 2) were observed in 19.6% of patients. The overall incidence of HVS was 158 per 1000 patients, and PTSD was 445 per 1000 patients. Multivariate logistic regression identified cognitive impairment (acute phase), persistent weight loss (post-COVID-19 phase), PCFS grade > 2, and PTSD as independent factors for developing HVS, with relative risks (RRs) of 3.47 (95%CI [1.48-8.31]; p = 0.004), 11.87 (95%CI [1.25-112.88]; p = 0.031), 3.24 (95%CI [1.34-7.86]; p = 0.009), and 5.98 (95%CI [2.27-15.77]; p < 0.001), respectively. Conclusion HVS is prevalent in the post-COVID-19 phase, affecting 15.6 % of survivors. Identified predictive factors suggest the convergence of psychosomatic pathophysiological mechanisms. Further research is crucial for a detailed understanding of these mechanisms in long COVID-19 patients.

Postantropocentryczny demos i porządek obywatelski
Authors: Pietrzak Edyta B.
Published: December 2024

THE POST-ANTHROPOCENTRIC DEMOS AND CIVIC ORDER
The aim of this article is to hermeneutically analyse the narratives associated with the post-anthropocentric turn and their implications for the transformation of political and civic order. These issues can be situated within a framework of broad political thought and theory based on the work of Rosi Braidotti, Karen Barad, Donna Haraway, Bruno Latour, or Michel Serres. Emphasising multispecies justice, the demands of post-humanist positions and adjustments to social theory refer to a concern for a stable future of human and non-human collectivities. They concern the expansion of the public sphere and the political emancipation of hitherto marginalised peripheral actors, reclaiming as they do their voice. This non-anthropocentric point of view refers to elements of nature as well as the technological world gaining legal status. This raises the question of its political consequences for society and the civil order. It involves the restoration or granting of legal and moral subjectivity to non-human entities. Will the next step, therefore, also be to give them political subjectivity and a revolution to match the new social contract? The structure of the text addresses issues such as the evolution of civil society, the possibilities and consequences of moving beyond the category of anthropos, the proposal of monism as ontological egalitarianism, the presentation of examples of non-human actors in the public sphere and Latour’s project of a parliament of things – the pluriversum.
Does access to ICTs equally matter for men and women in terms of academic exam performance? The case of middle education in Colombia
Authors: Rodríguez Arenas Jorge Leonardo , Gamboa Luis Fernando
Published: December 2024

This paper analyzes the impact of Information and Communication Technologies (ICT) on the academic performance of students in Colombia, specifically in mathematics and reading. Using data from secondary school students between 2017 and 2019, ICT access is measured through the availability of computers and Internet. The results indicate that access to ict improves mathematics scores by 0.068 standard deviations, while no significant effect is observed in reading. Additionally, having a computer without Internet access does not affect scores. These findings provide relevant insights for policies aimed at reducing the digital divide. No differential effects are found between males and females.

Published: December 2024

We have considered the conformal β – change of Finsler metric L given by L ̅ = e^σ f(L,β ), where f is any positively homogeneous function of degree one in L and 1-form β. We have obtained that due to this change of Finsler metric, the imbedding class of their tangent Riemannian space is increased at most by two.
Functional alignment minimizes changes to joint line obliquity in robotic-assisted total knee arthroplasty: a CT analysis of functional versus kinematic alignment in 2,116 knees using the Coronal Plane Alignment of the Knee (CPAK) classification
Authors: van de Graaf Victor A. , Clark Gavin W. , Collopy Dermot , Wood Jil A. , Chen Darren B. , MacDessi Samuel J.
Published: December 2024

Aims

Functional alignment (FA) in total knee arthroplasty (TKA) aims to achieve balanced gaps by adjusting implant positioning while minimizing changes to constitutional joint line obliquity (JLO). Although FA uses kinematic alignment (KA) as a starting point, the final implant positions can vary significantly between these two approaches. This study used the Coronal Plane Alignment of the Knee (CPAK) classification to compare differences between KA and final FA positions.

Methods

A retrospective analysis compared pre-resection and post-implantation alignments in 2,116 robotic-assisted FA TKAs. The lateral distal femoral angle (LDFA) and medial proximal tibial angle (MPTA) were measured to determine the arithmetic hip-knee-ankle angle (aHKA = MPTA – LDFA), JLO (JLO = MPTA + LDFA), and CPAK type. The primary outcome was the proportion of knees that varied ≤ 2° for aHKA and ≤ 3° for JLO from their KA to FA positions, and direction and magnitude of those changes per CPAK phenotype. Secondary outcomes included proportion of knees that maintained their CPAK phenotype, and differences between sexes.

Results

Overall, 71.6% had an aHKA change ≤ 2°, and 87.0% a JLO change ≤ 3°. Mean aHKA changed from -1.1° (SD 2.8°) in KA to -1.9° (SD 2.3°) in FA (mean difference (MD) -0.83 (SD 2.0); p < 0.001). Mean JLO changed from 173.9° (SD 3.0°) in KA to 174.2° (SD 2.6°) in FA (MD 0.38 (SD 2.3); p < 0.001). CPAK type was maintained in 58.1% of knees, with the proportion highest for Types I (73.9%), II (61.1%), and IV (51.2%). In valgus knees, 67.5% of Type III and 71.7% of Type VI were shifted to neutral phenotypes. There was minimal change to constitutional JLO across all CPAK types (MDs -2.0° to 1.2°).

Conclusion

Functional alignment may alter CPAK type, but does not significantly change JLO. A kinematic starting point minimizes changes to native anatomy, while final position with FA provides an optimally balanced TKA.

Artificial intelligence (AI) is revolutionizing various sectors, including health care, with orthopedics being no exception. Orthopedic practice, already familiar with technological advancements such as robotic surgery, is rapidly integrating AI into clinical workflows, enhancing precision in surgical planning, diagnostics, and patient care. However, this evolution raises critical questions, particularly regarding liability when AI systems fail and cause harm. This article delves into the role of AI in orthopedics, exploring its current applications and the potential legal implications that come with its adoption. It examines the global landscape, highlighting the lack of clear regulations around AI liability, especially in India, where the topic remains underexplored in medical literature. With insights into how AI is transforming orthopedic practice, the article addresses the pressing concern of who bears responsibility when AI errors occur. This timely discussion serves as an exploration of a unique and recent topic, urging Indian orthopedic surgeons to balance the benefits of AI with the responsibility they hold, as the legal framework surrounding AI in health care continues to evolve.

Introduction: Carpal tunnel syndrome (CTS) is the most common compressive neuropathy, often leading to significant impairment, especially in patients with bilateral involvement. When conservative trials fail, surgical options such as open, mini-open, and endoscopic carpal tunnel release are considered. This report highlights the use of single-stage bilateral mini-open carpal tunnel release, emphasizing its efficiency, reduced recovery time, and cost-effectiveness.

Case Report: A 58-year-old female with hypothyroidism presented with a history of numbness and tingling in the thumb, index, and middle fingers of both hands. Despite conservative management, symptoms persisted. The patient opted for a single-stage bilateral mini-open carpal tunnel release to save time and costs. The patient resumed daily activities within 2 weeks, showing significant improvement in disabilities of the arm, shoulder, and hand and Boston CTS questionnaire scores.

Conclusion: The mini-open technique for single-stage bilateral carpal tunnel release is an effective and efficient option for managing bilateral CTS. It provides adequate exposure and meticulous decompression, offering the benefits of both open and endoscopic methods while minimizing their drawbacks. This approach significantly improves patient outcomes and satisfaction.

Introduction: Prompt diagnosis and management of septic arthritis are pivotal for early infection eradication, joint preservation, and prevention of quality-of-life impact consequences. Total hip arthroplasty has been introduced for the management of severe destructive septic arthritis with the aims to eradicate infection while preserving hip function. Few case studies have been done on two-stage exchange total hip arthroplasty for treatment of native hip septic arthritis using prosthesis with antibiotic-loaded acrylic cement articulating spacer with generally good outcomes. However, a small percentage of patients electively chose not to proceed with the second-stage exchange arthroplasty. Therefore, 1.5-stage total hip arthroplasty was considered a viable option; however, it has only been established in periprosthetic infection management, but not in native hip septic arthritis. Custom-made articulating spacers are considered an ideal option as has no constraints, are more readily available, and were designed to be a functional single-stage spacer that can remain permanent yet not preclude the possibility of a second-stage exchange surgery if required. Overall, this led to the consideration of 1.5-stage total hip arthroplasty using custom-made articulating spacers for the management of chronic destructive hip septic arthritis.

Case report: We report a 67-year-old patient with functional decline from fully independent without aids to chairbound over 8 months. Work-up revealed raised inflammatory markers and bilateral destructive hip septic arthritis. He underwent bilateral 1.5-stage total hip arthroplasty with antibiotic-loaded custom-made articulating spacers. One-year post-operation, he remains infection-free and is progressing well with rehabilitation – ambulating independently with walking frame.

Conclusion: Management of septic arthritis varies largely depending on infection duration, activity level, and extent of joint destruction. In significantly destructed hip septic arthritis, 1.5-stage total hip arthroplasty using antibiotic-loaded custom-made articulating spacer is a viable option with the benefits of effective infection eradication, good functional outcomes, cost-effectiveness, reduced physical and psychological burden in avoiding a second operation, all whilst not precluding the possibility of a second-stage exchange arthroplasty if required with ease.

Introduction: Metacarpophalangeal (MCP) joint dislocation and its pathoanatomy was first discussed in detail in an article written by Kaplan et al . ,in 1957. They had identified certain features of complex, that is irreducible MCP joint dislocation through closed method to differentiate from a simple MCP joint dislocation, that is MCP joint dislocation that can be reduced by closed method. The complex MCP joint dislocations (mostly involving the index finger) are called Kaplan dislocations. Here, we describe two cases of MCP joint dislocations to highlight the differences between complex and simple MCP joint dislocation in their clinical appearances, X-rays, and management protocol.

Case Report: In the first case, the injured patient was a 17-year-old young cricketer, who sustained the injury while playing the game. After careful clinical examination and studying the X-rays, we assured the patient and treated his injury by closed reduction method. After undergoing the post-reduction splinting and physiotherapy, the patient has recovered completely and he is back to playing cricket. In the second case, the patient was an elderly lady; she got her left index finger dislocated while trying to forcefully hold a moving object. After careful clinical examination and studying the X-rays, we counselled her and treated her injury through open reduction method. After following the post-operative splinting and physiotherapy, the patient is doing well but her index finger extension is restricted in the terminal ranges.

Conclusion: The MCP joint dislocations have distinctive clinico - pathological patterns and we should carefully study them. We should not hesitate to adopt open reduction techniques in appropriately indicated patients.

Introduction: Aneurysmal bone cysts (ABCs) are benign, locally destructive, blood-filled reactive lesions of the bone most commonly presenting as pain or mass effect. Most are frequently located in the proximal humerus, distal femur, proximal tibia, spine, uncommonly the sacrum, and rarely the sacroiliac (SI) joint. We present a rare case of ABC in the SI joint and its recurrence treated with percutaneous intralesional doxycycline ablation and the corresponding outcome.

Case Report: A 29-year-old female presented with persistent gluteal pain and radiculopathy and was subsequently diagnosed with ABC in the left SI joint. She underwent intralesional extended curettage with the application of synthetic bone graft substitute over the defect. One year postoperatively, local recurrence of the mass was noted after presenting with similar symptoms of radiculopathy. She then underwent six sessions of CT-guided percutaneous intralesional doxycycline ablation at 2–3-month intervals. Serial monitoring through plain CT scan showed interval development of intralesional osseous formation and decreased lytic spaces. At the latest follow-up of 3½ years after treatment cessation, the patient remained asymptomatic with no recurrence.

Conclusion: This reports the only known local experience using non-invasive treatment for the recurrence of ABC in the SI joint through CT-guided intralesional ablation of doxycycline resulting in relief of symptoms and absence of recurrence at 3½ years post-treatment. This supports previous studies showing doxycycline administration as an effective alternative in the treatment of ABCs in recurrent cases, in challenging cases due to its location, or when located in non-expendable areas such as the SI joint and sacrum. More extensive studies with longer follow-ups are needed to validate these findings.

Integration and Design of Cryogenic Hydrogen Fuel Systems for Sustainable Commercial Aviation
Authors: DIACONU Tea-Maria
Published: December 2024

The transition to hydrogen-powered aircraft offers an opportunity to significantly reduce carbon emissions in commercial aviation. The use of renewable hydrogen in commercial aviation has the potential to significantly reduce the carbon footprint of the industry. Aviation currently accounts for around 3% of global carbon emissions, a figure that is projected to grow without the adoption of sustainable fuels like hydrogen [1]. Hydrogen can be stored as a compressed gas at high pressure and as a liquid at cryogenic temperatures. However, the unique properties of hydrogen, particularly its low density and cryogenic storage requirements need a complete redesign of aircraft fuel systems. The low density of hydrogen necessitates larger storage volumes compared to conventional fuels, and cryogenic storage requires maintaining extremely low temperatures to prevent boil-off, which can lead to significant fuel loss [2]. This research aims to develop innovative fuel system designs that can efficiently store and deliver cryogenic liquid hydrogen.
Numerous tank designs including cylindrical, spherical, and double-walled configurations will be explored. Cylindrical tanks are commonly used for high-pressure gas storage and must be designed to withstand pressure loads effectively. Spherical tanks offer a lower surface area-to-volume ratio, which is advantageous for reducing heat transfer and boil-off. Double-walled configurations provide additional insulation and structural integrity, essential for maintaining cryogenic temperatures [3]. Additionally, effective heat management is crucial in hydrogen fuel systems. The research will explore strategies to recover waste heat from fuel cells or combustion processes, which can be utilized to improve overall system efficiency. This is particularly important in preventing excessive boil-off in cryogenic tanks, which can lead to increased pressure and potential safety issues. By conceiving aircraft designs optimized for either direct liquid hydrogen combustion or fuel cell propulsion, this research aims to create sustainable aviation solutions.
Furthermore, this study will develop a detailed thermodynamic model to simulate the behaviour of cryogenic hydrogen fuel systems under various operating conditions, including heat transfer, phase changes and boil-off effects. The goal is to optimize the design and operation of hydrogen fuel systems to achieve maximum efficiency and safety. The findings from this research aim to provide a comprehensive framework for the future of hydrogen-powered commercial aviation. By addressing the unique challenges of hydrogen storage and fuel system design, the study seeks to contribute to the development of sustainable aviation solutions that can significantly reduce the carbon footprint of the airline industry.

This study presents light metal alloys used in the aeronautical industry, specifically focusing on their suitability for Friction Stir Welding (FSW) and Friction Stir Processing (FSP). These innovative techniques play an important role in improving the mechanical properties and performance of aluminum, magnesium, and titanium alloys, which are extensively utilized in aerospace applications due to their superior strength-to-weight ratios. FSW and FSP offer significant advantages in joining and processing materials, including enhanced weld integrity, defect reduction, and refined microstructural properties.

The thermal/ sensory gravity “S.O.S.” the last phase (40°–50° C) of global warming
Authors: DUMITRESCU Horia , CARDOS Vladimir , BOGATEANU Radu
Published: December 2024

The gravitational buckling is an ice hole or black hole in the frozen quantum binary space penetrated by the light ignition, the backscattering of radiant thermal energy, where the quantum light barrier (cs = 1010 m/s) breaks together with the thermal field polarisation (conventional positive and negative charges) in an internal gravitational field. The light ignition triggers off the quantum recurrent autocatalytic reactions, whose metastable phase equilibrium is controlled by gravity to hold dawn fixed warming thresholds levels inside/ within the solar system. In the out-order working function, a limit and critical gravity switches the thermal regime until the catalytic equilibrium is restored. The π – quantum automorphism of light functions as NTC thermistors or gravity protective shield neutralizing PTC thermistors (e – quantum automorphism) when their reaction rate will increase rapidly with overheating of their products. Physically, the role of NTC thermistor or thermal gravity is played by the mixture of C12 and C14 carbon isotopes of critical solar mass found in satellites (terrestrial and Galilean moons), concentrated in two gravitational metastable equilibrium centres: one warm centre, 𝑔𝑔0, (the Earth, 2730 K – temperature and another cold centre, 𝑔𝑔𝑡𝑡ℎ=𝑔𝑔024 (the Jupiter, 1730 K – temperature). The terrestrial, warm metastable catalytic climate is given by the warm focus (𝑔𝑔0) with the seawater temperatures (15-200 C) and the equinox-solstice temperatures (25-400 C), where the solar reactive mass is at the limit of the C12 – carbon isotope, with the light flux 𝛷𝛷𝐿𝐿=𝑒𝑒3𝜋𝜋3𝑐𝑐𝑠𝑠=6×1012𝑚𝑚2𝑠𝑠3 (𝑐𝑐𝑠𝑠=1010𝑚𝑚𝑠𝑠, the self-ignition velocity). The equilibrium catalyst of the dual quantum automorphism for frozen chemistry is considered to be the so-called the Lesser Bear or UMI asterism. The Jovian cold non-equilibrium critical climate is the result of the thermal/cold focus (𝑔𝑔𝑡𝑡ℎ=𝑔𝑔024=25𝑚𝑚𝑠𝑠2) with the equinox temperature (20–250 C) and the summer-solstice temperature (42–500 C). When the cold focus exceeds 𝑔𝑔𝑡𝑡ℎ,𝑙𝑙𝑙𝑙𝑙 =𝑒𝑒𝑔𝑔0 𝑚𝑚/𝑠𝑠2, the last phase of global warming is produced, i.e. the thermal radiation displacement of the solar mass from the C12 – carbon isotope to the C14 – carbon isotope is achieved, along with the light flux limit: 𝛷𝛷𝐿𝐿,𝑙𝑙𝑙𝑙𝑙 =𝑒𝑒4𝜋𝜋3𝑐𝑐𝑠𝑠=3/2×1013𝑚𝑚2𝑠𝑠3, beyond the solar reaction products results in a thermo-nuclear explosion.The Jovian critical climate is associated with thermo-gravity waves, felt as intense thermal circulation with worse predictions (less three days), strong winds/vortices and abnormal temperature increases (towards red spectrum). These severe warming effects will continue without interruption until their cause is understood and eliminated: the tendency of such self-contained system to exceed its limits in relation to the overpopulated human habitat and its restoration by severe effects of global warming.
Controlling directional propagation in driven two-dimensional photonic lattices

Published: December 2024

Controlling light propagation in photonic systems fosters fundamental research and practical application. Particularly, photonic lattices allow engineering band dispersions and tailor transport features through their geometry. However, complete controllability requires external manipulation of the propagating light. Here, we present a resonant excitation scheme to observe quasi-1D and uni-directional propagation of light through the bulk of two-dimensional lattices. To this end, we use the highly anisotropic light propagation exhibited at the energy of saddle points in photonic bands. When multiple drives with judicious amplitudes and phases are tuned to such energy, interference effects between these drives and photonic modes result in controllable directional propagation through the bulk. Similarly, one can form localized states with controllable localization degrees. We illustrate these effects by simulating driven photonic lattices composed of dissipative resonators. Our theoretical work highlights the importance of external drives for dynamically controlling directional light transport in lattices, a relevant feature for all-optical routing and processing in photonics.

Published: December 2024

In this study, three distinct hydrogen bonding (HB) states of tetrahydrofuran (THF)-aqueous solutions at varying concentrations were characterized and analyzed using Raman spectroscopy coupled with two-dimensional correlation Raman (2D-COS) analysis. Specifically, in the range of 10%≤NTHF ≤ 30%, the solution exhibits cluster structures characterized by free THF-5H2O and THF-4H2O tetrahedral configurations; in the range of 40%≤NTHF ≤ 70%, the cluster structures within the solution consisted of THF·2H2O and THF·H2O configurations, following the fragmentation of tetrahedral structures; in 80%≤NTHF, the disruption of the tetrahedral structure of water enters the second stage, resulting in the formation of 2THF·H2O and low-dimensional self-aggregated structures of THF. Combined with density functional theory, a further discussion on the changes in bond lengths and bond angles was conducted. The results indicate that with the increase of NTHF, the HB length initially shortens and then elongates, the dihedral angle first increases and then decreases, and the corresponding bond energy increases initially and then decreases.

Published: December 2024

The characterization of the complex spectral amplitude, that is, the spectrum and spectral phase, of single-photon-level light fields is a crucial capability for modern photonic quantum technologies. Since established pulse characterization techniques are not applicable at low intensities, alternative approaches are required. Here, we demonstrate the retrieval of the complex spectral amplitude of single-photon-level light pulses through measuring their chronocyclic Q −function. Our approach draws inspiration from quantum state tomography by exploiting the analogy between quadrature phase space and time-frequency phase space. In the experiment, we perform time-frequency projections with a quantum pulse gate (QPG), which directly yield the chronocyclic Q −function. We evaluate the complex spectral amplitude from the measured chronocyclic Q −function data with maximum likelihood estimation (MLE), which is the established technique for quantum state tomography. The MLE yields not only an unambigious estimate of the complex spectral amplitude of the state under test that does not require any a priori information, but also allows for, in principle, estimating the spectral-temporal coherence properties of the state. Our method accurately recovers features such as jumps in the spectral phase and is resistant against regions with zero spectral intensity, which makes it immediately beneficial for classical pulse characterization problems.

Published: December 2024

We present a dual focus wavefront tilting metalens, a lens of a few micrometers thick that compensates for incidence angles of ±5° and focuses them to the same target. The metalens comprises an array of Si3N4 nanopillars. We manufactured the metalens using 193 nm deep-ultraviolet scanner lithography, suitable for high-volume manufacturing. Using this metalens, we demonstrate a proof-of-concept for chip-to-free-space coupling by directing light from one fibre collimator at +5° towards a mirror and recoupling this light into another fibre collimator at -5°. The metalens achieved a focusing efficiency of 9.4%. This efficiency has the potential to be improved to 64%. The metalens can be integrated into photonic circuits for enhanced coupling with distant objects. This work paves the way for further miniaturization of gas and metrology sensors.
Enhancing plasmonic structured illumination microscopy with surface plasmon coupled emission
Authors: Huang Ming , Jiang Kaiwen , Shen Zhe
Published: December 2024

Plasmonic structured illumination microscopy (PSIM) is a super-resolution technique that utilizes surface plasmon polaritons (SPPs) with higher frequency as the structured light; thus, it is able to break the diffraction limit with a 3–4 times resolution enhancement. However, the low efficiency of near-field fluorescence collection results in a low imaging signal-to-noise ratio (SNR) of PSIM. In this paper, we propose a method to enhance the performance of PSIM with surface plasmon coupled emission (SPCE). Compared to conventional fluorescence detection, it achieves a 5-fold enhancement in fluorescence collection efficiency by collecting SPCE signals, which facilitates better collection of near-field information of targets. In our PSIM, samples with different fluorescence excitation wavelengths are distinguished by adjusting the collection angle, since SPCE has high wavelength sensitivity. Especially, the technique of fluorescence emission difference (FED) for SPCE was used to obtain a 5.7-fold resolution enhancement, which further enhanced the super-resolution capability of PSIM. This method improves the SNR and resolution of PSIM and facilitates more detailed observation of biological cells.
