Методом численного моделирования изучаются отличия и особенности распространения в вертикальном канале волн гетерогенной детонации в капельно-воздушных газовзвесях н-гексадекана и изо-октана - горючих жидкостей с сильно различающейся летучестью паров при нормальных условиях. Различие в летучести паров приводит к тому, что условия существования гетерогенной детонации в капельно-воздушных газовзвесях н-гексадекана и изо-октана сильно различаются. Если в капельно-воздушных газовзвесях изо-октана гетерогенную детонацию в канале можно инициировать без принятия каких-либо специальных мер, то инициировать гетерогенную детонацию, например в стехиометрической капельно-воздушной газовзвеси н-гексадекана, можно только при степени предыспарения жидкости выше некоторого критического значения (около 40%). При степени предыспарения жидкости ниже этого критического значения химическое энерговыделение за лидирующей ударной волной не обеспечивает самоподдерживающийся характер распространения волны реакции. При переходе через критическое значение степени предыспарения жидкости происходит смена режима энерговыделения в волне реакции: в ней появляется период быстрого (кинетически лимитированного) самовоспламенения паровоздушной смеси за лидирующей ударной волной со значительным повышением температуры, которое ускоряет последующие процессы смесеобразования и (диффузионно-лимитированного) энерговыделения. При докритическом значении степени предыспарения этот период выражен слабо.

Published: December 2024

This research compares e-procurement applications in Indonesia and Malaysia, which are the applications of e-procurement as a renewal of the goods/services procurement system. Malaysia and Indonesia have implemented e-procurement, and the presence of corrupt practices has made both countries focus on increasing transparency. The number of procurement transactions in Indonesia increased significantly from 2008 to 2017, with total spending reaching more than 1000 trillion Rupiah in 2020. The number of online e-procurement transactions in Malaysia has decreased from 2014-2015, with an overall decrease in transactions from 1,577,740 to 1,540,314. The results showed that Malaysia and Indonesia conducted Peer Exchange activities to exchange experiences and knowledge about Ecolabeling and GPP.  Green procurement can use e-procurement as one of the methods to ensure transparency and efficiency in the procurement process. E-procurement can help control inventory, reduce costs, and improve agreement conformity with suppliers. Therefore, the author would like to compare the implementation of the system in Indonesia and Malaysia in terms of the procurement of goods/services.

Grammatical unidirectionality is not reflected in individual preferences when performing artificial semantic extension
Authors: Kapron-King Anna , Kirby Simon , Trousdale Graeme , Smith Kenny
Published: December 2024

Grammaticalization is when lexical items (e.g., nouns) change to be used as grammatical items (e.g., prepositions). This kind of change is widespread throughout the world's languages. Change in the opposite direction, from more to less grammatical, is far less common and systematic. We ran two artificial language experiments to test whether this unidirectional tendency originates with an individual preference for extending lexical meanings to grammatical ones rather than extending grammatical meanings to lexical ones. We focus on the extension of body parts to spatial relations. In our first experiment, participants were told the English meaning of an artificial word and asked to rate how likely it is that that word can also be used to refer to a second meaning -- one meaning was a body part and the other was a preposition. We expected lower ratings when the first meaning was a preposition compared to when it was a body part, but we found no difference. For the second experiment, participants were paired up to perform semantic extension in a communication task. We varied whether they were extending words for body parts to spatial prepositions or vice versa. Again, we found no evidence of an asymmetric bias. Finally, we used a computational model of the second experiment to show that participants would have behaved asymmetrically if they had more words to use than meanings to express, indicating that having a larger number of lexical items than grammatical concepts could be an alternative source of unidirectionality.
The motivational component of the cognitive model
Authors: Halkin Oleksandr
Published: December 2024

The theoretical basis of cognitive therapy, the cognitive model, explains the emotional reactions of individuals by the peculiarities of their perception. An individual perceives the world through the prism of personal experience, presented in the form of a certain structure, that influences the formation of internal reactions in response to stimuli. To designate this structure, in addition to the term "personal construct" introduced by G. Kelly, others are also used, such as cognitive patterns, schemes, cognitive habits, perception characteristics, etc. The vagueness of terminology reflects the insufficiently studied depth and complexity of the processes of perception, which negatively affects the effectiveness of cognitive therapy. An attempt to clarify was made by A. Beck in the Generic cognitive model, which mentions the cognitive, affective, motivational, and behavioral components of perception patterns. The role of motives is undoubtedly important in the process of perception. It is no exaggeration to say that the influence of motives can be traced in everything that a person does. Core beliefs, the main element of the scheme and the goal of cognitive therapy, are formed under the influence of motives, rely on motives, and their transformation cannot but affect the motivational sphere. With this approach, the motive appears as the basis, the foundation of the scheme.
Growth and Changing Landscape of the Cost-Utility Literature: An Australian Perspective, 1992-2022

Published: December 2024

Objectives: To provide a comprehensive overview of the volume, trends, and characteristics of the use of cost utility analysis (CUA) in healthcare decision making in Australia.Design and setting: Bibliometric analysis of published studies on CUA identified from the Cost-Effectiveness Analysis Registry, a comprehensive source of CUA data, between 1992-2022. Main outcome measures: Australian-based CUAs using cost-per-quality adjusted life years (QALYs) or cost-per-disability adjusted life years (DALYs) as the outcome, as well as the trends and relevant characteristics of the CUAs.Data synthesis: A total of 488 unique Australian-based CUAs were analysed (cost-per-QALY: n=398; cost-per-DALY: n=90). Over the last three decades, the volume and quality of CUAs in Australia have steadily increased. Interventions that were frequently evaluated were on pharmaceuticals (21.7%), health education/behaviour (18.0%), and models of care (16.7%), while diseases of the circulatory system, cancers, and metabolic diseases were the most studies health conditions. Most CUAs (72.7%) were conducted from a healthcare payer perspective, with only 19.0% adopting a broader societal perspective. A 5% discount rate applied in about half of studies. Half (50.6%) of the studies used a $50,000 WTP threshold, followed distantly by thresholds between $28,001-$49,999 (5.3%) or $28,000 (3.9%). Most studies were funded by academic/government sources (61.7%), while 14.5% were supported by the pharmaceutical or medical device industry. Overall, 60.2% of QALY studies reported an ICER less than $28,000, and 71.5% less than $50,000, resulting in a 11.3% gap. For DALY studies, there was a 12.3% gap (74.1% - 61.8%) in the proportions reporting ICERS between threshold of $28,000 and $50,000. Conclusions: The increasing volume of CUAs underscores the importance of efficient allocation of scare resources in the Australian health system. However, gaps remain in standardised reporting and reevaluating the alignment of discount rates and WTP thresholds with international standards, which require further research for more equitable healthcare resource allocation.
Systematic need-led design to develop low-cost solutions to healthcare challenges remotely
Authors: Venkatramani Aishwarya , Kulkarni Manali , Hamed Radhwa
Published: December 2024

In light of the COVID-19 pandemic and the concurrent expansion of health facilities globally, it has become increasingly apparent that addressing health innovation and the delivery of healthcare services requires a focus on remote solutions and the remote transfer of knowledge. Traditional frameworks like Human-Centred Design (HCD) are often challenged when adapted to remote environments, particularly in healthcare settings that differ culturally, politically, and infrastructurally from the location of their development. This paper proposes a systematic, need-led design pipeline tailored for the remote creation of cost-effective healthcare solutions. By incorporating a series of sequential stages and adapting existing HCD frameworks, we aim to effectively address specific medical requirements in remote locations. We focus on the challenges, considerations, and necessary adaptations for successful implementation across diverse healthcare environments. Through empirical evidence from a healthcare project in Ghana, we illustrate how HCD can be effectively applied in remote settings to develop user-centred solutions with sensitivity to their broader socio-cultural dynamics. This study contributes to the discourse on HCD's applicability in remote healthcare innovation, advocating for a more nuanced approach that integrates cultural, ethical, and systemic considerations to enhance the efficacy and relevance of health interventions globally.
Predictive vs. Prospective Control: Clarifying the Terms of the Debate
Authors: Wilson Andrew D , Buckingham Gavin , Dessing Joost C. , Lappi Otto , Friston Karl , Hipolito Inês , Ramstead Maxwell James , Mansell Warren , Gray Rob
Published: December 2024

A central question in motor control is whether that control is predictive or prospective. However, these terms are used widely and inconsistently throughout the literature, which makes it hard for research to reliably build or be challenged. Our goal is to clearly identify the ways in which these terms get used, and to identify what each approach commits to as a theory of motor control. We have identified three notions of predictive control (Perception-Action, Predictive Processing, and the Free Energy Principle) and two of prospective control (Perceptual Control Theory, and Ecological Psychology), and here we briefly discuss what each entails, with reference to key literature and examples. We hope that this guide will help researchers be clear about exactly which approach they are taking, and how they have engaged with the key elements of their chosen approach.
Unraveling the reciprocal effects and micro-development of metacognitive monitoring strategies and monitoring judgments: A micro-genetic diary study
Authors: Händel Marion , Nett Ulrike , Bryce Donna , Dresel Markus
Published: December 2024

Metacognitive monitoring plays a central role in models focusing either on monitoring strategies (models of self-regulated learning) or on monitoring judgments and their accuracy (models of metacognition). Although strategies and judgments are both concerned with monitoring one’s learning progress, they have been analyzed only independently, so far. To combine these two research perspectives, an integrative model is proposed. Two studies empirically tested the structure of metacognitive monitoring and investigated the influence of metacognitive knowledge and motivational components. The studies focused on general (Study 1, N = 396) and situation-specific (Study 2, N = 225) monitoring as well as on quantitative and qualitative aspects of monitoring (both studies). Across the two studies, monitoring one’s own learning was characterized by three separate but correlated factors: use of monitoring strategies, quality of monitoring strategies, and accuracy of monitoring judgments. Furthermore, common (metacognitive knowledge, expectancy) and specific (value) predictors of metacognitive monitoring were identified.
RECOGNITION OF HIRAGANA JAPANESE HANDWRITING CHARACTERS USING SUPPORT VECTOR MACHINE AND SCALE INVARIANT FEATURE TRANSFORM
Authors: Chintia Wardhani Putu Raditha , Florestiyanto Mangaras Yanu
Published: December 2024

The abundance of characters in Japanese Hiragana, the similarity in character shapes, and the lack of familiarity among the public with Hiragana in daily life make it difficult to learn. People tend to be more accustomed to romanized writing (alphabet) than specific characters, leading to difficulties in understanding Hiragana with its various sizes and shapes. This research aims to develop an effective and systematic Japanese Hiragana handwritten recognition system using Support Vector Machine (SVM) and Scale Invariant Feature Transform (SIFT) methods. The research methodology includes problem identification, literature review, data collection, data preprocessing, system design, implementation, and evaluation. The obtained data undergo augmentation and image preprocessing processes to create a larger variety and amount of data. Furthermore, feature extraction is performed on the data using the SIFT method before training the model using SVM. The research results show that the SVM-SIFT model achieves an accuracy of 0.928261, which is superior to the SVM model without SIFT with an accuracy of 0.389130. The best CV score for the SVM model without SIFT is 0.7746709410609622. Testing proves that the use of SVM SIFT is effective for classifying handwriting that varies in shape and size.

RECONCILIATION AND ISLAMISATION: A ROADMAP FOR AN ISLAMIC INTELLECTUAL REVIVAL
Authors: Syeed Safiyyah Sabreen , El-Muhammady Ahmad
Published: December 2024

The Muslim world produced one of the greatest intellectual
revolutions in history. Since the Colonial Period, the effort to bring
about a global Islamic Revival has been a much sought after project
for Muslim intellectuals worldwide. This paper studies the core
principles that were instrumental in building the Islamic Intellectual
Revolution (8th-18th Century CE). These core principles are
identified as the centrality of the Qur’an in all intellectual discourse,
a broad epistemological landscape and the unity of the sacred and
secular sciences. This paper explores how returning to the same
methodology can lead to an Islamic intellectual revival. The Qur’an
identifies eight valid epistemic sources apart from itself while
declaring itself as the Furqan (Criterion) to judge their validity.
These include Sunnah, human intellect (‘Aql and Qiyas), Ijma’
(consensus), intuition (Basira), the physical universe, history, and
certain knowledge from other civilisations. It is the duty of the
scholars to work towards an integration of knowledge derived from
these different sources and thus ‘Islamise’ them. This paper identifies
the core reasons for the present intellectual crisis to as being rooted
in an ignorance of the broad epistemological landscape of Islam.
The Qur’an anticipates how a better understanding of the self
and the cosmos will lead to a validation of the truth of the Qur’an in
the future (41:53). Contemporary scientific discourse has uncovered
important perspectives related to these two domains, presenting a
good opportunity for Muslim intellectuals to study them in the light of
Islamic thought. It is argued that science today needs a new
philosophical paradigm as breakthroughs in physics and cosmology
have made the current mechanistic and deterministic philosophy of
science obsolete. This paper discusses how a new Islamic philosophy
of science that rests on the Kalām and Sufi view of the universe and
consciousness is one of the best contenders for this change in
paradigm. Developments in Quantum Physics, Fine Tuned
Cosmology, and the Hard Problem of Consciousness are taken as
case studies to propose solutions from Islamic thought to
conundrums related to them. Thus, a practical guide to the
Islamisation of the fields of cosmology, physics, biology, and
neuropsychology is proposed and it is argued that this approach will
inevitably revitalise Muslim thought, reconcile physical sciences with
it and thus has the potential to bring about an intellectual revival in
the Ummah.
IBN SINA’S CONTRIBUTIONS TO MODERNITY: INTEGRATING MEDIEVAL PHILOSOPHY, NEUROPHILOSOPHY, AND EDUCATIONAL REFORM IN ISLAMIC THOUGHT AND CIVILISATION
Authors: Norman Nurul Ain , Ruhullah Mohammad Eisa
Published: December 2024

This study explores the enduring legacy of Ibn Sina, a seminal figure
in Islamic medieval philosophy, focusing on his theory of the soul
and its implications for modern neurophilosophy, educational
reform, and the renewal of Islamic thought and civilisation. By
bridging the intellectual heritage of Ibn Sina with contemporary
discussions in neurophilosophy, this paper highlights his
contributions to understanding the nature of consciousness,
perception, and the human mind. Furthermore, it examines how Ibn
Sina's insights can inform modern educational practices, advocating
for an integration of classical wisdom and scientific advancements
within the curriculum of Islamic studies. This integration not only
pays homage to the rich intellectual tradition of Islamic civilisation
but also fosters a dialogue between the medieval and the modern,
contributing to the ongoing process of renewal and reform in Islamic
thought. By applying Ibn Sina’s philosophical principles to
contemporary challenges in education and society, this research
underscores the potential for medieval Islamic philosophy to
contribute to modernity, offering innovative pathways for navigating
the complexities of the 21st century.
Cardiovascular Medication Saving Activity during Dispensing Process at Specialist Clinic Pharmacy in Malaysia
Authors: V Mohamed Koya Saiful Nizam M
Published: December 2024

Background: Medication saving activity via reduction of medication supply due to medication refusal by patients during dispensing process is a vital activity that can be led by the pharmacists. However, there is a lack of evidence on how to conduct this activity especially at specialist or outpatient pharmacy for those patients diagnosed with cardiovascular disease (CVD). Thus, this study aimed to determine prevalence, factors and cost associated with patients’ refusal to the CVD medication supply during dispensing process by pharmacist at specialist clinic pharmacy. Methods: Patients prescribed with CVD medications were invited to participate in this cross-sectional survey after medication dispensing process was completed. This process involved assessing participants’ refusal to the dispensed CVD medication and issues related to their treatment. Data regarding cost was obtained from Pharmacy Information System (PhIS) at the current facility. Results: A total of 270 patients participated in this survey. Prevalence of participants refusing medication prescribed was 33.7%. Participants receiving care from primary and secondary healthcare simultaneously, experiencing side effects and self-modified treatment were 4.88 (P = 0.027), 5.01 (P < 0.05) and 2.98 (P = 0.018) times more likely to refuse medications dispensed. Those who participated in ‘Medication Therapy Adherence and Counselling’ (MTAC) program however were 0.43 times less likely to refuse medication during dispensing process, (P = 0.012). A saving of 4.8% was achieved from this activity. Conclusion: Cost-saved achieved during this study was minimal and factors associated with medication refusal was rather concerning.
Delayed percutaneous intradiscal hydrogel herniation causing neurological injury after minor trauma: illustrative case
Authors: Gopalakrishnan Sowmya , Far Rena , Veilleux Catherine , Swamy Ganesh , Yang Michael M. H.
Published: December 2024

BACKGROUND

Percutaneous intradiscal hydrogel injection has been used to treat low-back pain (LBP) due to degenerative disc disease with or without mild radicular pain. Complications from these procedures are underreported. In this case lesson, the authors present a rare case of a patient with herniated intradiscal hydrogel following a minor trauma leading to neurological injury.

OBSERVATIONS

A 36-year-old female who had been previously treated with L4–5 and L5–S1 intradiscal hydrogel injections for LBP presented with painful, progressive right-sided lower-extremity weakness after experiencing a twisting trauma. Cross-sectional imaging results revealed a herniated hydrogel-based disc implant in the spinal canal. She underwent an urgent L4–5 laminectomy for decompression and removal of the herniated implant. A large annular defect was noted. Postoperatively, she had resolution of her right leg pain but experienced persistent right foot drop requiring an ankle-foot orthosis.

LESSONS

Herniated intradiscal hydrogel implants can lead to permanent neurological injury. While the risk factors for hydrogel herniation have not been elucidated, they can be related to pre-existing disruptions to the annulus and/or posterior longitudinal ligament, excess volume of hydrogel injection, and insufficient fixation time. Further research is needed to determine the safety and efficacy of this technology.

Management of atraumatic chin-on-chest deformity in newly diagnosed multiple myeloma: illustrative case
Authors: Karimi Helen , Sastry Rahul A. , Shao Belinda , Abdulrazeq Hael , Li Xun , Niu Tianyi
Published: December 2024

BACKGROUND

Patients with multiple myeloma (MM) are commonly managed by multidisciplinary oncology teams in concordance with the neurological, oncological, mechanical, and systematic decision framework. Surgery is indicated for mechanical instability and/or neurological deficits. In neurologically intact and mechanically stable patients, chemo- and radiotherapy alone are often the mainstay treatment.

OBSERVATIONS

A 66-year-old male patient presented with a kyphotic chin-on-chest deformity due to undiagnosed spinal MM. He experienced progressive neck pain and difficulty with activities of daily living (ADLs). Imaging revealed systematic bony element destruction and burst deformities at T1–2 with cervicothoracic central canal stenosis. Due to his disease burden and neurological preservation, spinal alignment was initially achieved via halo traction and immobilization, allowing him to begin systemic therapy almost immediately after diagnosis and improving vertebral bone density and construct integrity prior to surgery. He underwent C2–T10 decompression and instrumented fusion with cement augmentation. At 12 months postoperatively, the patient reported improvement in symptomology and ADLs without radiographic evidence of hardware failure or spinal instability.

LESSONS

Spinal MM with instability can be successfully managed with gradual deformity realignment and external orthosis before surgery in a neurologically intact patient with a significant disease burden.

Management of severe traumatic brain injury in a rivaroxaban overdose: illustrative case
Authors: Foertsch Madeline J. , Beckett Henry T. , Dehne Lauren M. , Janusz Stephanie , Ferioli Simona , Ngwenya Laura B. , Droege Molly E.
Published: December 2024

BACKGROUND

The management of rivaroxaban overdose in severe traumatic brain injury (sTBI) is undocumented. Reversal with andexanet alfa (AA) and prothrombin complex concentrates (PCCs) in cases of supratherapeutic doses remains unproven. Management is further complicated by the absence of real-time serum rivaroxaban concentration assays and drug-specific coagulation assays. This report details the use of plasma exchange (PLEX) in combination with PCC and AA to manage rivaroxaban overdose in sTBI.

OBSERVATIONS

A 36-year-old female presented with sTBI. Her admission international normalized ratio was 4.8 and thromboelastography reaction time was 85 seconds. Chromogenic low-molecular-weight heparin anti-Xa (AXA) concentration was < 0.1 units/mL. PCC and vitamin K were administered but failed to improve coagulopathy. Further history revealed a possible rivaroxaban overdose, and AA was administered. The second AXA prior to AA was > 1.8 units/mL. AXA remained > 1.8 units/mL 3 hours after AA. PLEX was urgently initiated prior to surgery for drug removal. Serum rivaroxaban concentrations pre- and post-PLEX were 534.6 and 256.8 ng/mL, respectively. A hemicraniectomy was performed without intraoperative or postoperative bleeding complications.

LESSONS

Routine reversal strategies may be insufficient in achieving hemostasis in rivaroxaban overdose. PLEX reduced serum rivaroxaban concentration by 52%. PLEX can be an important adjunct to consider for medical and perioperative management of rivaroxaban overdose.

Intrathecal baclofen pump for severe hypertonia in a patient with juvenile Huntington’s disease: illustrative case
Authors: Winston Graham M. , Nilchian Parsa , Greenfield Jeffrey P. , Jones Dara
Published: December 2024

BACKGROUND

While the symptoms of Huntington’s disease (HD) typically first appear around the age of 40 years, 5%–10% of patients experience symptoms before the age of 21 years, in which case it is classified as juvenile Huntington’s disease (JHD). JHD poses a unique clinical problem, as affected patients experience rapid deterioration in their quality of life as the motor manifestations of the disease become overwhelming. Medical treatment options for HD are sparse, and the only Food and Drug Administration–approved medication for the treatment of HD is the VMAT-2 inhibitor tetrabenazine. Unfortunately, treatments for JHD are even more limited, as investigational new drugs for HD oftentimes exclude patients with JHD from trials.

OBSERVATIONS

Here, the authors present the case of a 15-year-old male with severe hypertonia and dystonic events secondary to JHD that was successfully treated with an intrathecal baclofen (ITB) pump. The patient experienced an improvement in hypertonia and a reduction in the frequency of dystonic events after ITB pump implantation, resulting in overall improved patient comfort.

LESSONS

This case highlights the potential benefits of ITB therapy in managing debilitating hypertonia-type symptoms in patients with JHD. Given the limited treatment options for JHD, this intervention has the potential to profoundly enhance the quality of life for affected individuals.

Transient cerebral ischemia in pituitary apoplexy–induced internal carotid artery occlusion: illustrative case
Authors: Xue Stanley , Li Ching Ng Angela , Chen Nicholas , Khong Peter
Published: December 2024

BACKGROUND

Cerebral ischemia secondary to occlusion or vasospasm of adjacent large vessels is a rare but significant complication of pituitary apoplexy. Misdiagnosis can lead to delays in management and devastating neurological outcomes. This case is the first reported instance of an initial presentation with transient cerebral ischemic symptoms, in addition to a classic pituitary apoplexy syndrome, for this clinical entity of pituitary apoplexy with adjacent large vessel occlusion.

OBSERVATIONS

A 49-year-old man presented with a classic pituitary apoplexy syndrome of headache, vomiting, and hemianopia, with transient preceding expressive dysphasia and right-hand numbness. Computed tomography (CT) and CT angiography of the brain demonstrated a large apoplectic pituitary tumor and associated occlusion of the left internal carotid artery. Subsequent CT perfusion studies revealed a threatening large ischemic penumbra in the left middle cerebral artery territory. He underwent urgent transsphenoidal resection of the pituitary tumor, resulting in symptom resolution and the prevention of cerebral infarction.

LESSONS

The recognition of transient cerebral ischemic symptoms in pituitary apoplexy should encourage the exclusion of any large-vessel complications and resultant cerebral ischemia. Early assessment, particularly with angiography and perfusion studies, can assist in guiding management, which is usually surgical decompression, distinct from traditional treatment for cerebrovascular events.
