Advancing the Recognition of Women in African Philosophy
Authors: Maponya Dimpho Takane 
Published: December 2024

Abstract
In this article, I examine the marginalisation of women, specifically in African philosophy, with the aim of cautioning and inspiring a reconfiguration of African philosophy that takes seriously the discourse of gender as it does the discourse of race. I employ Charles Taylor's notion of recognition to understand some of the effects of a lack of recognition, which I then extend to the lack of recognition of women in African philosophy. I present this understanding against the background of the ongoing debates and efforts of decolonisation by illustrating how the marginalisation of women in African philosophy places the discipline at odds with decolonisation and its emancipatory objective. African philosophy, in the process of legitimising its existence, has adopted a male-centred framework which has not only undermined the existence of women but also failed to recognise their contributions. This has influenced the practice and discourse of African philosophy, resulting in the underrepresentation of women therein.
Creolising the State?
Authors: Gordon Jane Anna 
Published: December 2024

Abstract
While the Euromodern model of the nation-state has been the subject of unremitting, exhaustive and merited political criticism, this article advances an anti-anti-statism. Oriented by warnings of theorists who have advanced plurinational states, creolising the nation, separating states from nations and abolishing the state, I turn to Fanon's insistence that states be re-envisioned beyond Cold War alternatives and narrowing nationalisms; Cabral's modelling of political unity on an effective football team; and Gyekye's suggestion of deliberately forging meta-national states. I argue that we need the institutional rejection of states reliant on racialised enslavement and colonialism as the exclusive custodians of bestowing and withholding political recognition. We must also premise rightful belonging not only on historical group identities but on how these are expressed in records of political activities demonstrating commitment to the cultivation and extension of national consciousness or the meta-state as the basis of political legitimacy.
Treatment of occult radiculopathy in complex regional pain syndrome by anterior cervical discectomy and fusion following localization by [18F]fluorodeoxyglucose radioligand and PET/MRI: illustrative case
Authors: Schonfeld Ethan , Haider Ghani , Tawfik Vivianne , Jin Michael C. , Yoo Kelly , Marianayagam Neelan J. , Biswal Sandip , Veeravagu Anand 
Published: December 2024

BACKGROUND
The inability to localize pain generators often results in failed back surgery syndrome (FBSS). Structural imaging can identify multiple and/or noncausative abnormalities. Molecular imaging of glucose transporters offers the opportunity to localize metabolically active sites. Using the radiotracer [18F]fluorodeoxyglucose (FDG) with positron emission tomography/magnetic resonance imaging (PET/MRI) has enabled the localization of malignant lesions and pain generators via regions of high inflammation.

OBSERVATIONS
A 61-year-old woman was diagnosed with complex regional pain syndrome (CRPS) and experienced right greater than left upper-extremity pain. Following PET/MRI with the FDG radioligand for GLUT, increased radiotracer uptake was seen in the right C6 nerve root and dorsal root ganglion, providing additional information to the structural MRI findings of narrowing of the right C5–6 neural foramina. Together with pain relief following a transforaminal steroid injection to the area, these results prompted the authors to perform a C5–6 anterior cervical discectomy and fusion procedure, which resulted in significant symptom relief.

LESSONS
The authors present a case of worsening upper-extremity CRPS with an occult radiculopathy that improved following surgery to address a pain generator identified by FDG PET/MRI. Localization of inflammatory sites can reduce FBSS and nonspecific management of pain believed to be resulting from spinal pain generators in a wide array of chronic pain syndromes.

Visual impairment associated with direct compression of the visual cortex due to subdural hematoma following foramen magnum decompression: illustrative case
Authors: Nakayama Yosuke , Yamana Satoshi , Nogami Ryo , Fuga Michiyasu , Sano Tohru , Kawamura Daichi , Murayama Yuichi , Ohashi Hiroki 
Published: December 2024

BACKGROUND
Postoperative subdural hematoma (SDH) typically presents with headache, impaired consciousness, hemiplegia, gait disturbance, and aphasia but can also present with visual impairment.

OBSERVATIONS
A 52-year-old woman diagnosed with Chiari malformation type I and syringomyelia underwent foramen magnum decompression. Cerebrospinal fluid was lost due to arachnoid injury during the procedure. Postoperatively, a small acute SDH was apparent in the posterior convexity on head computed tomography but was managed conservatively because no neurological deficits were present. Visual impairment developed 2 weeks postoperatively. Ophthalmological examination showed right lower quadrantanopia with normal anterior ocular segment and fundoscopic findings. Magnetic resonance imaging demonstrated SDH in the left posterior convexity with direct compression of the visual cortex. Conservative treatment reduced the hematoma and improved visual impairment.

LESSONS
SDH in the posterior convexity can cause visual impairment via direct compression of the visual cortex. SDH should be included in the differential diagnosis for patients presenting with visual impairment following craniotomy.

Brown-Séquard syndrome after blunt cervical spine trauma in a patient with preinjury multilevel hemilaminectomies and OPLL: illustrative case
Authors: Torres Jose , Kim Kevin T. , Yarmoska Steven K. , Serra Riccardo , Crandall Kenneth M. 
Published: December 2024

BACKGROUND
Brown-Séquard syndrome (BSS) is a rare neurological condition characterized by injury to one-half of the spinal cord. In the context of trauma, BSS is typically seen with penetrating injuries. Here, the authors present the unique case of a patient presenting with BSS after blunt trauma.

OBSERVATIONS
A 70-year-old male with a history of right cervical hemilaminectomies from C4 to C6 and ossification of the posterior longitudinal ligament (OPLL) presented after a motor vehicle collision. He had left-sided weakness (American Spinal Injury Association [ASIA] grade C with a motor score of 45 and a neurological level of C4), left-sided sensory loss, and right-sided loss of sensation to painful stimulation. Magnetic resonance imaging revealed significant spinal cord compression from C2 to C6, with intramedullary signal from C2 to C5. The patient underwent urgent C2–6 laminectomies with C2–5 instrumented fusion. Intraoperative ultrasound confirmed complete decompression as well as visualized a hyperechoic signal, particularly in the left C3–4 hemicord, evident of spinal cord injury. Postoperatively, his ASIA motor score improved to 56 at the 6-week follow-up.

LESSONS
This case highlights a unique scenario in which prior decompressive surgeries could have provided a protective effect on the spinal cord at the levels with concomitant OPLL and hemilaminectomies, potentially preventing complete tetraplegia.

A rare case of cervical myelopathy due to a bipartite atlas: degenerative complications and surgical outcome. Illustrative case
Authors: Otsuka Munehiro , Miyamoto Takanobu , Ohara Jiro , Hoshimaru Minoru , Ueda Shigeo 
Published: December 2024

BACKGROUND
A bipartite atlas is a rare congenital anomaly characterized by incomplete fusion of the anterior and posterior arches of the first cervical vertebra (C1). While typically asymptomatic, this condition can result in cervical myelopathy when accompanied by degenerative changes. This report presents a rare case of cervical myelopathy caused by a bipartite atlas in an older patient that required surgical intervention.

OBSERVATIONS
A 63-year-old male presented with progressive neurological symptoms, including impaired fine motor skills, pain, and paresthesias in both the upper and lower extremities. Imaging revealed a bipartite atlas accompanied by degenerative changes, resulting in significant spinal cord compression. The patient underwent a posterior decompression via C1 laminectomy and duraplasty, resulting in significant clinical improvement and a resolution of symptoms.

LESSONS
This case highlights the importance of recognizing a bipartite atlas as a potential cause of cervical myelopathy, particularly in older patients with degenerative changes. This is a rare case in which congenital and degenerative factors are intertwined, underscoring the importance of a comprehensive pathological analysis and the development of a personalized treatment strategy. Prompt diagnosis and appropriate surgical intervention are essential for favorable outcomes.

Diagnostic challenges of diffuse leptomeningeal glioneuronal tumor in an adult female: illustrative case
Authors: Ma Lichao , Meng GuoLu , Tang Jie , Hou Yuanzheng 
Published: December 2024

BACKGROUND
Diffuse leptomeningeal glioneuronal tumor (DLGNT) is a rare central nervous system tumor, especially in adult females. Typically, it presents with leptomeningeal enhancements in the basal cisterns and spinal cord. However, varied radiological and pathological features can complicate the diagnosis, as the present case illustrates.

OBSERVATIONS
An adult female presented with severe headache, blurred vision, and cognitive impairment. Elevated intracranial pressure (ICP) was detected via lumbar puncture. Brain magnetic resonance imaging (MRI) revealed atypical unilateral basal cistern enhancement, differing from the usual symmetrical DLGNT presentation. Despite high ICP, only mild ventricular enlargement was observed. Noncontrast spine MRI failed to demonstrate spinal leptomeningeal enhancement. A stereotactic biopsy of an occipital lesion was inconclusive. These atypical findings led to misdiagnoses of viral encephalitis or inflammation at two hospitals. Significant symptom relief occurred only after ventriculoperitoneal (VP) shunt surgery. Over 2.5 years, intraparenchymal lesions in the parahippocampal gyrus grew, necessitating surgical intervention. Pathological examination finally confirmed DLGNT. Postsurgery, the patient underwent chemotherapy with temozolomide and remains symptom free.

LESSONS
This case underscores the critical importance of comprehensive initial imaging, strategic biopsy planning, and timely placement of a VP shunt in patients with DLGNT. It contributes to the literature by revealing atypical imaging features and long-term progression patterns of DLGNT.

Macromolecules with crown ether groups represent a fundamentally new type of sorbents whose active centers are ligands that retain electroneutrality during simultaneous binding of cations, anions or organic compounds. The aim of this work is to study the conditions for the preparation of polymeric sorbents containing diaminodicyclohexyl crown-ethers and to investigate the activity of these sorbents with respect to the extraction of alkali metal cations. Chemical grafting of cycloaliphatic crown ethers onto a macroporous chloromethylated copolymer of styrene and divinylbenzene was carried out. Under selected conditions, diaminodicyclohexyl-18-crown-6 produced polycrown- ethers with a content of crown-ether groups of 1.42 mmol/g, while diaminodicyclohexyl-24-crown-8 produced a content of macrocyclic groups of 1.24 mmol/g. The recovery of alkali metals under static conditions by grafted type sorbents based on different macrocycles has been investigated. High values of distribution coefficients of alkali metals (Na+, K+, Cs+) by synthesized sorbents in acidic medium are shown. The following selectivity series were found for the sorbent with diaminodicyclohexyl-18-crown-6 fragments: К+ ˃ Cs+ ˃ Na+, and for the sorbent with diaminodicyclohexyl-24-crown-8 fragments: Cs+ ˃ K+ ˃ Na+. The efficiency of the obtained sorbent for the extraction of alkali metal cations was shown.

This study investigates the potential of ion-plated aluminum technology for modern industrial applications by applying a protective coating to 20# steel and evaluates the macroscopic and microscopic morphology, thickness (8∼13μm), bonding strength, and performance of the coating in highly corrosive environments. Experimental results indicate that ion-plated aluminum technology significantly improves the surface properties of the untreated material, with the corrosion current decreasing from 10-0.77A/cm2 to 10-2.75A/cm2. Additionally, after a neutral salt spray test, the samples exhibited no white corrosion products after 96 h and resisted red rust formation for up to 360 h. This analysis demonstrates that ion-plated aluminum technology enhances the service life and reliability of materials, offering an environmentally friendly alternative to conventional metal coatings and showing significant potential for broad industrial applications.
An efficient algorithm for reducing the number of Add‐Drop Multiplexers in SONET/WDM rings
Authors: Li Guangzhi , Simha Rahul 
Published: December 2024

This paper considers a network design problem introduced by Gerstel, Lin and Sasaki (INFOCOM'98) in which resource allocation is performed within a Wavelength Division Multiplexing (WDM) optical ring network to reduce overall equipment cost. The problem can be summarized as follows. The Add‐Drop Multiplexers (ADM's) that are used to terminate lightpaths in an optical (SONET/SDH) ring are expensive. A naive implementation would require ADM's for each wavelength at each node. However, by carefully assigning connections to wavelengths and routing the resulting lightpaths, one may avoid terminating all wavelengths at every node, and thereby reduce the number of ADM's needed. While Gerstel et al. consider wavelength assignment with respect to this problem, they do not consider the additional complication of routing. In this paper, we consider joint routing and wavelength assignment, and show that the number of ADM's required is significantly less than the number resulting from applying the heuristics in Gerstel et al. Our algorithm analyzes connection requirements and, using a decomposition based on Euler paths, performs routing and wavelength assignment.
Approaches to Neutronic Calculations to Justify the Lifetime Extension for VVER-1000 Control Rods
Authors: Mazurok O. , Ivanov V. , Godun O. , Zuyok V. , Makarenko A. 
Published: December 2024

The uninterrupted operation of Ukrainian NPPs depends not only on timely delivery of fresh fuel, but also on the supply of a number of other critical core elements. One of these critical elements is control rods, which have their own lifetime and need to be replaced on a regular basis. If the diversification of nuclear fuel suppliers has been ongoing since the early 2000s [1], the diversification of control rods was at the initial stage at the beginning of the full-scale invasion and its completion requires some time to conduct the relevant tests and trial operation in the reactor core.
For temporary meeting the NPP need for control rods, it was decided to justify lifetime extension for them by determining the residual lifetime. Control rod lifetime extension is based on the determination of the residual lifetime using an approach that takes into account control rod actual position during all fuel campaigns in which the control rods were operated. Excessive conservatism was laid due to the assumption that the immersion of the 10th working group in the core during all fuel campaigns is 70 %, but the actual position is 85–90 %. To reduce conservatism, it is necessary to take into account the actual position of the emergency control groups during all fuel campaigns in which the control rods were part of the control group that requires a large number of neutronic calculations to determine the neutron fluence and absorbing element burnup (boron-10).
The obvious approach to determining the fluence of fast neutrons and boron burnup in absorbing elements is currently the use of the Monte Carlo method, which allows modeling neutron transport without any serious assumptions and approximations of the computational model, and, accordingly, present the most accurate results. The main disadvantage of Monte Carlo codes is that the simulation of complex systems is a long-term computational process, which can become a limiting factor. Considering the need to take into account the actual operation schedule of each control rod, the application of the Monte Carlo method to justify the operability in the lifetime extension for control rods is extremely problematic.
The approach to neutronic calculations using the HELIOS code is proposed in the paper in terms of determining the fluence of fast neutrons and burnup of the boron-10 isotope in absorbing elements. The approach is based on the application of the neutron transport solution in two-dimensional geometry based on the method of the first collision probability and the subsequent synthesis of two- and one-dimensional neutron flux density distributions. The implemented approach is characterized by an accuracy comparable to the Monte Carlo method but is much more efficient in terms of computer time spent for calculations, which allows a large amount of calculations to be performed to justify the lifetime extension for each individual control rod, taking into account the real history of operation.
