Published: September 2024

Abstract
Background The cervical spine is prone to various conditions necessitating early detection. Morphometric analysis through computed tomography (CT) scans plays a pivotal role in diagnosing and preventing severe diseases. This study focuses on understanding the morphometric details of the cervical canal in the West Indian population, addressing a geographical gap in existing literature. The primary objective of this study was to perform a morphometric analysis of the cervical spine to study the implications it can have on cervical canal stenosis in the West Indian population.
Materials and Methods This study utilizes imaging data from the CT database of 100 individuals (73 men and 27 women). Measurements such as transverse canal diameter, sagittal canal diameter, cross-sectional canal surface area (CSA), and vertebral body diameter (VBD) were collected and the Pavlov-Torg ratio (PTR) was calculated from C2 to C7.
Results Notable findings include significant differences in CSA and VBD between genders, while PTR indicated cervical damage in 40% of participants. Multinomial regression was applied which signified an association between weakness and PTR.
Conclusion This study can be used to highlight the CT scan's importance in studying bony structures and the call for more region-specific morphometric studies. The variations in morphometric parameters could provide insights into understanding the vulnerabilities of a population belonging to a particular geographic area, in our case, the West Indian population.

Published: September 2024

AbstractDengue virus is an arbovirus transmitted through the bite of infected Aedes mosquitoes. Many unusual clinical features are being reported in dengue. Dengue complicated with hemophagocytic lymphohistiocytosis (HLH) is a rare but potentially fatal condition. Here, we report an 18-year-old otherwise healthy female with dengue fever complicated with HLH. The diagnosis was made by fulfilling the clinical and laboratory criteria of HLH. She was managed successfully with a methylprednisolone pulse regimen. Our case highlights the importance of early recognition of complications and prompt treatment for a better outcome.

Published: September 2024

AbstractThe use of adjuvants in brain surgery has increased. Artificial adjuncts are being used in neurosurgery frequently. These foreign materials may result in a foreign body reaction inside the normal brain tissue surrounding the areas of pathology. This material may mimic an abscess or tumor in their presentation and masquerade the magnetic resonance (MR) or computed tomography (CT) image as recurrence, abscess, or granuloma. We present a case of a 42-year-old woman with a history of hypertensive basal ganglia bleeding who was operated on in an emergency. Decompressive craniectomy and clot evacuation were carried out. A thin layer of Gelfoam was applied in the operated area. After 4 weeks, she was planned for cranioplasty where an oval soft to firm yellowish lesion was found at the site of the previous cavity of the evacuated clot, which was sent for biopsy and it was confirmed as a Gelfoam granuloma. Meticulous use of hemostatic agents in the form of small surgical or thin waferlike gelatin sponges should be used intraoperatively. Large-size Gelfoam and artificial agents can lead to foreign body–like granulation tissue formation in normal brain tissue and several complications like hydrocephalous, meningitis, and seizures. Peculiarities in this case include the following: Gelfoam granuloma is a very rare complication following cranial surgery, it was mimicking like an abscess, and the size of Gelfoam used intraoperatively should be a thin wafer coating the raw surface or in the cavity.
An Unusual Presentation of Chronic Subdural Hematoma—“Subdural Mud”
Authors: R. Arvind K. 
Published: September 2024

AbstractChronic subdural hematoma (SDH) is widely seen in neurosurgical practice, however, the incidence of calcification or ossification in chronic SDH is a rare finding with an incidence of 0.3 to 2.7%. We report a case of an 85-year-old male after having undergone a parietal burr hole craniectomy for left-sided chronic SDH at a hospital in his locality, presented with a drop in conscious level, Glasgow Coma Scale of 9/15 (E3V1M5) with left-sided hemiparesis. A computed tomography scan revealed a thick left subdural collection with multiple densities along with a right capsuloganglionic bleed with intraventricular extension, which was successfully and completely removed, with progressive clinical improvement. Intraoperatively, as the SDH had the consistency and color, like that of mud/clay with thick membranes, it is referred to as “subdural mud.” In our case, surgical intervention did improve the neurological and functional outcome of the patient which supports the fact that surgery is indicated in patients with calcified chronic SDH with acute or progressive neurological deterioration.
Immunoglobulin D-Lambda Multiple Myeloma Initially Presenting in the Sphenoid Sinus, Orbital Apex, and Skull Base: A Systematic Review with a Case Report
Authors: Chen Yihan , Liu Jianfeng , Zhao Jianhui 
Published: September 2024

Abstract
Objectives Multiple myeloma (MM) with initial manifestations in the sphenoid sinus, orbital apex, and skull base is exceedingly rare. A systematic review was conducted to investigate the epidemiology and advancements.

Methods Relevant cases were identified by searching CNKI, WanFang Data, CQVIP databases, PubMed, Embase, and Web of Science. Additionally, we present a case of IgD-λ (immunoglobulin D-lambda) MM with initial symptoms of dizziness, unilateral pain, blindness, and ophthalmoplegia, leading to a 4-month overall survival. Strictly based on PRISMA standards, we included and summarized existing cases and reflected our case.
Results Our systematic review includes 34 case reports, revealing 67.6% of patients initially presented with diplopia and 44.1% underwent endoscopic procedures, notably with only two cases of IgD-λ subtype. In our case, we performed an endoscopic wide trans-ethmoidal sphenoidotomy and biopsy of the skull base and orbital apex lesion. Postoperative pathology confirmed a highly active plasmacytoma, clinically diagnosed as IgD-λ MM with a TP53 deletion mutation and multiple extramedullary metastases. A range of diagnostic tools was employed, including hemoglobin, immunoglobulin, urinary protein analysis, positron emission tomography-computed tomography (CT), bone marrow cytology, and gene detection.
Conclusion The subtle clinical manifestations of IgD-λ MM in the paranasal sinuses and skull base hinder early diagnosis. There is a paucity of literature describing MM initially presenting in these locations. CT/magnetic resonance scans are necessary to identify characteristic bone destruction. An endoscopic approach is popular for tissue biopsy. Bone marrow biopsy with a smear, serum or urine protein electrophoresis, and immunofixation electrophoresis are crucial upon the appearance of target organ damage.

Published: September 2024

Abstract
Objectives The study aimed to investigate the clinical and radiological characteristics of acute leukoencephalopathy with restricted diffusion (ALERD) among pediatric patients presenting with acute encephalopathy, seizures, and fever.
Methods A retrospective analysis was conducted on 48 pediatric patients who underwent magnetic resonance imaging (MRI) between April 2022 and August 2023 at Bapuji Hospital, J.J.M. Medical College, Davanagere, Karnataka, India. Inclusion criteria comprised acute-onset encephalopathy, fever, seizures, and MRI evidence of acute subcortical white matter involvement. Clinical and radiological data were collected and analyzed to delineate ALERD characteristics.
Results Among the study cohort, 18.7% of cases met the diagnostic criteria for ALERD, predominantly affecting male children with a mean age of 32 months. Clinical presentations varied, including biphasic and monophasic courses. Two distinct patterns of brain involvement, diffuse and central-sparing, were identified. Laboratory abnormalities and differential diagnoses were elucidated, providing insights into distinguishing ALERD from other conditions. MRI, particularly diffusion-weighted imaging, emerged as a crucial tool for ALERD diagnosis, revealing characteristic restricted diffusion patterns.
Conclusion The study underscores the importance of recognizing ALERD as a distinct clinical-radiological syndrome associated with infections, aiding in timely diagnosis and management. Understanding the varied clinical presentations and radiological patterns enhances diagnostic accuracy, emphasizing the role of MRI in ALERD diagnosis. These findings contribute to a comprehensive understanding of ALERD, facilitating improved patient outcomes and prognosis.
A sociolinguistic study of the palatal fricative in Venezuelan Spanish
Authors: Díaz-Campos Manuel , Pollock Matthew 
Published: September 2024

Abstract
The Spanish palatal fricative /ʝ/, a site of considerable social variation, is examined in Caracas,
Venezuela, comparing productions across a 20-year period. Based on spectrographic and acoustic analyses, we identify
four allophones of the palatal fricative. While approximant use in Caracas has fallen from 1987–2013, it is still the
dominant allophone, and young speakers from the 2010s show increased use. Several linguistic factors, including
previous context, tonicity, and segment duration predict allophone production; however, social factors including
gender, corpus year, and speech rate suggest that stratification exists. Through a diachronic analysis, this study
provides insight into allophonic variation and social meaning in Caracas across two generations during a time of
sociopolitical change.
The present progressive as a future marker in Spanish, English, and Spanish in contact with English
Authors: Zahler Sara L. , Tolentino Rocío Leguisamon 
Published: September 2024

Abstract
We examined the acceptance of the present progressive (e.g., I am traveling) with
future meaning (PPF) by 82 monolingual English, monolingual Spanish, and heritage Spanish speakers. Participants
evaluated on a scale of 1–5 the acceptability of the PPF in 20 contexts that were embedded in a narrative in which we
manipulated the surrounding discourse for temporal reference, event certainty, and presence of a locative marker.
Results indicate that heritage Spanish speakers evaluated the PPF differently in English and Spanish, and differently
from both monolingual groups. These findings indicate that the effects of language contact in U.S. Spanish-English
bilinguals is bidirectional and that heritage Spanish speakers maintain two distinct systems for the PPF in Spanish
and English.
Ven, Vení, Venga
Authors: Vaughn Stevi , Ronquest Rebecca , Michnowicz Jim 
Published: September 2024

Abstract
The present investigation contributes to our understanding of the evolving linguistic communities
in the Southeastern U.S. by examining the factors that drive speakers’ choice of second person singular pronouns
(e.g., tú, vos, usted). Results indicate that context and origin are the most influential factors:
Argentines maintain their use of vos in familiar contexts, while Central Americans increase their use
of tú and usted over time. However, although Argentines maintain a higher use of
vos than Central Americans overall, they show evidence of accommodation to both
tú and usted in contexts where they interact with speakers of other Spanish
varieties. Qualitative analyses revealed an avoidance of voseo despite its strong ties to identity,
indicating a complex interplay between pronoun choice.

Abstract
This study investigates electron emission from copper broad-area emitters (CBAEs) and copper broad-area composite emitters (CBACEs) based on the principles of trapping and conductive pathways. Emission current measurements were conducted on two CBACEs, which consisted of copper coated with a 300–400 μm epoxy resin and subjected to high voltages up to 15 kV. The research specifically examines the ‘switch-on’ and collapse phenomena occurring within the epoxy layer. Field emission microscopy (FEM) was utilized in a high-vacuum environment (

mbar) to observe these effects. A comprehensive model is developed to explain the formation of conductive pathways within the epoxy layer, allowing electrons transfer from traps to the surface. This model treats the composite emitter as a trap-rich capacitor. The study also clarifies the effects of trap density and epoxy layer thickness on the collapse process. To gain a deeper understanding of the model, changes in the I-V curve were examined. Simulations, scanning electron microscopy-energy dispersive x-ray spectroscopy (SEM-EDX) images, and Fourier transform infrared spectroscopy (FTIR) analysis were employed to understand the collapse mechanism of the epoxy collapse. Additionally, Nyquist and Cole–Cole plots were analyzed across frequencies ranging from 1 to

A comparative study of total and partial ionization cross sections, branching ratios and fragmentation patterns of XH4 (X = C, Si, Ge, Sn, Pb)
Authors: Song Yunliang , Ma Yuwei , Li Bowen , Chen Ximeng 
Published: September 2024

Abstract
The formation and decomposition of SnH4 has been recently reported using electron ionization mass spectrometry (J. Am. Soc. Mass Spectrom. 35 (2024) 1523 and J. Vac. Sci. Technol. A 41 (2023) 063209) due to its importance in tin contamination cleaning in extreme ultraviolet lithography. A comprehensive understanding of the fragment patterns of SnH4 requires total and partial ionization cross sections of SnH4. However, there is limited availability of experimental and theoretical ionization data for SnH4. We report the electron-impact ionization fragmentation patterns of XH4 (X = C, Si, Ge, Sn, Pb) and should provide missing data, especially for SnH4 and PbH4. Total ionization cross sections are calculated using the Binary Encounter Bethe (BEB) method. Partial ionization cross sections and branching ratios are determined using mass spectrum data (MSD) and Huber et al’s method. Finally, we compare the calculated percentage abundances for the fragments of XH4 with experimental measurements.
Fano mode based plasmonic sensor for temperature and chemical pollutant detection
Authors: Yadav Gaurav Kumar , Metya Sanjeev Kumar 
Published: September 2024

Abstract
Plasmonic sensors provide great sensitivity to minute quantities of analytes and provide excellent detection. In present context of environmental monitoring, plasmonic sensor can prove to be an excellent choice in chemical pollutant and temperature detection. Plasmonic sensors can provide immediate results, allowing for monitoring temperature changes in ecosystems or climate studies and quick decision-making in emergency situations related chemical pollution incidents. They are compact and can be integrated into portable devices for on-site analysis. In this investigation, a plasmonic refractive index sensor based on key ring shaped resonator consisting of a microring resonator and two rectangular resonator is proposed. Finite-Difference Time-Domain (FDTD) method is used to study the transmittance characteristics of the sensor. The device exhibits quadruple Fano resonance with highest sensitivity of 2521.7 nm/RIU. Other performance parameters such as figure of Merit (FOM), Quality (Q) factor and Detection limit (DL) are also been calculated, with values 98.8 RIU−1, 99.6 and 0.01 respectively. Additionally, the effects of different geometrical configurations is also studied, providing insights into the design principles in context of potential fabrication complexities. Further, the simulated Fano characteristic is validated against the theoretical value. The application of the proposed sensor is investigated for different types of analyte such as chemical pollutants and temperature sensing.
Glimmers from the axiverse
Authors: Gendler Naomi , Marsh David J.E. , McAllister Liam , Moritz Jakob 
Published: September 2024

Abstract
We study axion-photon couplings in compactifications of type IIB string theory. We find
that these couplings are systematically suppressed compared to the inverse axion periodicity, as a
result of two effects. First, couplings to the QED theta angle are suppressed for axion mass
eigenstates that are light compared to the mass scale set by stringy instantons on the cycle
supporting QED. Second, in compactifications with many axions the intersection matrix is sparse,
making kinetic mixing weak. We study the resulting phenomenology in an ensemble of 200,000
toy models constructed from the Kreuzer-Skarke database up to the maximum Hodge number
h1,1 = 491. We examine freeze-in production and decay of thermal axions, birefringence of the
cosmic microwave background, X-ray spectrum oscillations, and constraints on the QCD axion from
supernovae. We conclude that compactifications in this corner of the landscape involve many
invisible axions, as well as a handful that may be detectable via photon couplings.
On the Riemann–Hilbert problem for the reverse space-time nonlocal Hirota equation with step-like initial data
Authors: Hu Bei-Bei , Zhang Ling , Shen Zu-Yi , Lin Ji 
Published: September 2024

Abstract
In this paper, we use the Riemann–Hilbert (RH) method to investigate the Cauchy problem of the reverse space-time nonlocal Hirota equation with step-like initial data: q(z, 0) = o(1) as z → −∞ and q(z, 0) = δ + o(1) as z → ∞, where δ is an arbitrary positive constant. We show that the solution of the Cauchy problem can be determined by the solution of the corresponding matrix RH problem established on the plane of complex spectral parameter λ. As an example, we construct an exact solution of the reverse space-time nonlocal Hirota equation in a special case via this RH problem.
Phase space analysis of interacting and non-interacting models in f(Q, C) gravity
Authors: Samaddar Amit , Singh Dr. Sanasam Surendra 
Published: September 2024

Abstract
Using a dynamical system method, we have studied a Friedmann-Robertson-Walker (FRW) cosmological model within the context of $f(Q,C)$ gravity, where $Q$ is the non-metricity scalar and $C$ represents the boundary term, considering both interacting and non-interacting models. A set of autonomous equations is derived, and solutions are calculated accordingly. We assessed the critical points obtained from these equations, identified their characteristic values, and explored the physical interpretation of the phase space for this system. Two types of $f(Q,C)$ are assumed to be $(i)$ $f(Q,C)=Q+\alpha Q+\beta C logC$ and $(ii)$ $f(Q,C)=Q+\alpha Q+\frac{\beta}{C}$, where $\alpha$ and $\beta$ are the parameters. In Model I, we obtain two stable critical points, while in Model II, we identified three stable critical points for both interacting and non-interacting models. We look into how the phase space trajectories behave at every critical points. We calculate the values of the physical parameters for both systems at each critical point, indicating the Universe's accelerated expansion.
