Abstract
Introduction Neurenteric cysts (NECs) are rare, congenital lesions lined by endodermal cell-derived columnar or cuboidal epithelium. Based on previous studies, gross total removal of the capsule has been presumed to be the ideal surgical goal.
Objective This series was undertaken to further understand the risk of recurrence based on the extent of capsule resection.
Methods Records were retrospectively reviewed for all patients with radiographic or pathological evidence of intracranial NEC from 1996 to 2021.
Results A total of eight patients were identified; four of eight (50%) presented with headache, and four had signs of one or more cranial nerve syndromes. One patient (13%) presented with third nerve palsy, one (13%) had sixth nerve palsy, and two (25%) with hemifacial spasm. One patient (13%) presented with signs of obstructive hydrocephalus. Magnetic resonance imaging demonstrated T2 hyper- or isointense lesions. Diffusion-weighted imaging was negative in all patients (100%) and T1 contrast-enhanced imaging demonstrated minimal rim enhancement in two patients (25%). In three of eight (38%), a gross total resection (GTR) was achieved, while in four (50%), a near-total resection, and in one (13%), a decompression was performed. Recurrences occurred in two (25%) patients, one with decompression and another with near-total resection, among these 1/2 required repeat surgery after a mean follow-up of 77 months.
Conclusion In this series, none from GTR group demonstrated recurrence, while 40% of those receiving less than GTR recurred, underpinning the importance of maximally safe resection in these patients. Overall patients did well without major morbidity from surgery.

Published: February 2022

AbstractBrainstem cavernoma is a challenging neurosurgical pathology and microsurgery remains the only treatment option. Although the decision-making between interventional and conservative approach to this disease may be complex, malformations presenting multiple bleedings are usually good candidates for surgery.1 On the other hand, microsurgical resection of cavernomas can offer an effective resolution with acceptable morbidity.In this video, we present a case of pontine cavernoma with multiple hemorrhages in a young patient. The anatomical characteristic of the lesion defines the best suitable craniotomy for surgery. In this case, an anterior petrosal approach2
3
4 was used to access the peritrigeminal area and safely perform the resection. Anatomical considerations are described on this skull base approach along with the rationale and benefits of this exposure. Electrophysiological neuromonitoring is essential for this kind of procedure and preoperative tractography also enabled the best understanding of the disease. Finally, we also discuss alternative managements and potential complications.5
With the patient's consent, we also show the excellent clinical evolution after few weeks of recovery and the restoration of the corticospinal tract, previously displaced by the cavernoma, to its original position.

Abstract
Objectives The objectives of this study were to compare the long-term shear bond strength of conventional adhesive on metal brackets with that of adhesive precoated brackets in vitro and to evaluate the amount of adhesive remnant on the tooth surface after debonding.
Materials and Methods A total of 90 maxillary permanent premolars were randomly divided into two groups. The samples in the first group were bonded with metal brackets using Transbond PLUS Color Change Adhesive (TP), and the samples in the second group were bonded with Flash-Free adhesive precoated brackets (APC FF). The bonding techniques were performed, according to the manufacturer's instructions. The samples from each group were randomly divided into three subgroups with different thermal cycles (n = 15). The shear bond strength (SBS) and adhesive remnant index (ARI) were measured and calculated.
Statistical Analysis Two-way ANOVA and Chi-square test were used to analyze the differences in the SBS and ARI between the groups, respectively.
Results The means of the SBS of the APC FF subgroups were significantly lower than those of the TP subgroups, except in the 10,000 thermocycle subgroups. Chi-square test showed no statistically significant differences between the groups and subgroups. An ARI score of 1 was the predominant score in both groups.
Conclusions This study found that the SBS of APC FF gradually increased with time and thermal aging did not affect the failure pattern.

Authors: Tabriz David M. , Arslan Bulent 
Published: February 2022

AbstractCentral venous occlusions (CVOs) of the major intrathoracic veins (jugular, subclavian, brachiocephalic, superior vena cava) can cause debilitating symptoms, negatively impact arteriovenous fistula/graft function, or limit potential access creation options in end-stage kidney disease (ESKD) utilizing hemodialysis (HD). This review summarizes the incidence, pathophysiology, indications/contraindications, and management options of CVOs in the ESKD on HD population and concludes with considerations and examples when planning endovascular central recanalization procedures, which have risen as the first-line management when appropriate.
HeRO Graft: Indications, Technique, Outcomes, and Secondary Intervention
Authors: Tabriz David M. , Arslan Bulent 
Published: February 2022

AbstractThe Hemodialysis Reliable Outflow (HeRO) graft is a nontraditional, surgical, and endovascularly placed access that offers options in failing arteriovenous fistula/arteriovenous graft or catheter-dependent patients. The HeRO graft provides a unique option and is specifically referred to in the 2019 Kidney Disease Outcomes Quality Initiative (KDOQI) vascular access update. The interventional radiologist has a role and opportunity to work collaboratively with surgeons in assisting with (1) the identification, selection, preparation for, and placement of HeRO grafts and (2) providing post-placement maintenance to ensure long-term patency.

Published: February 2022

AbstractHuman immunodeficiency virus (HIV) infection among women predisposes them to human papillomavirus (HPV) infection, the causative agent for cervical cancer. The study retrospectively analyzed the data of 291 women living with HIV AIDS (Acquired immunodeficiency syndrome) to assess the prevalence and determinants of the HPV infection and cervical intraepithelial neoplasia (CIN). The study found a high prevalence of cervical HPV infection (34.4%), CIN I (6.2%), and CIN II+ (8.6%). Participants with HPV DNA positivity are significantly more likely to be aged younger than 35 years (odds ratio [OR] = 1.64, 95% confidence interval [CI] = 1.01–2.69), housewives (OR = 2.29, 95% CI = 1.31–3.99), married at <20 years of age (OR = 2.02, 95% CI = 1.13–3.58), and have been pregnant more than two times (OR = 1.76, 95% CI = 1.08–2.87). Participants with CIN II+ are significantly more likely to be not married (OR = 3.363, 95% CI = 1.302–8.686). Considering the high prevalence of HPV and CIN observed among HIV women, it is worthwhile to integrate cervical cancer awareness programs and screening with routine follow-up of HIV patients at antiretroviral therapy clinic. This susceptible population needs attention to reduce the burden of cervical cancer in the country.
Island Stories: Mapping the (im)mobility trends of slow onset environmental processes in three island groups of the Philippines
Authors: Ayeb-Karlsson Sonja , Uy Noralene 
Published: February 2022

AbstractThere is an immediate lack of people-centred empirical evidence investigating how slow onset events influence human (im)mobility across the globe. This represents an important knowledge gap that makes it difficult for climate policy to safeguard vulnerable populations (whether on the move or left behind). In this study, 48 qualitative focus group discussions in the Philippines elaborated around people’s (im)mobility pathways in the context of slow onset events. The selected collective storytelling approach effectively mapped out the (im)mobility trends of 12 different origin- and destination locations involving the perceptions of 414 women and men across six provinces on Luzon, the Visayas and Mindanao islands. The research findings delicately outlined people’s translocality and its interlinkage with their personal (im)mobility experiences. People described how slow onset events such as longer-term soil and water degradation often contributed to reduced livelihood sustainability that influenced their decisions to move or stay. At the very core of people’s narratives were the ways that the environmental changes and (im)mobility experiences influenced people’s wellbeing. Some people described how temporary migration could increase their social status and boost wellbeing after returning home. Others described adverse impacts on their mental health during their migration experiences due to loss of place, identity, food, and social networks. The research findings show how policy can better support those moving, hosting, or identifying as immobile, as well as where (geographically and socially) more assistance is needed.
Energy spectrum and energy budget of superfluid turbulence using two-fluid shell model
Authors: Bhadra Abhiroop , Mishra Pankaj Kumar 
Published: February 2022

Using a two-fluid shell model, we numerically investigate the energy spectrum and the scale by scale energy budget for superfluid turbulence in the temperature range of T = 0.9–2.175 K. Both the normal and superfluid components exhibit the Kolmogorov-like spectrum (Ek ∼ k−5/3) in the inertial range for all the temperatures. The scale to scale energy budget analysis in the wavenumber space indicates a strong coupling between the normal and superfluid components at low temperature (T = 0.9 K), which is quite evident from the observation of balancing between the viscous dissipation and the energy transfer due to the mutual friction between the components at low temperature for the normal component. We also compute the temporal probability distribution function of the energy induced by the mutual friction to a particular component, which indicates the positive energy supply at low temperature (T = 0.9 K) and negative energy supply at high temperature (T = 1.9 K) for the normal component. The results are consistent with the previous numerical and experimental studies.
A systematic review of international students’ sexual health knowledge, behaviours, and attitudes

Published: February 2022

The demand for higher education has increased student mobility across the world. Studying abroad provides an opportunity for young adults to engage in sexual behaviours, some of which may be risky. Yet, little is known about international students’ current sexual health knowledge or practices. The aim of this review was to identify their sexual health knowledge, behaviours, and attitudes. A search of five databases yielded 21 studies that met inclusion criteria. These studies used quantitative (n = 13), qualitative (n = 7) and mixed methods (n = 1) and included a total of 4666 international and exchange students from diverse cultural backgrounds. Findings were grouped into three themes: sexual health knowledge, sexual behaviours, and sexual health attitudes. Asian international students had poorer levels of knowledge, suggesting a need for culturally appropriate sex education. They were less sexually experienced and were older than domestic students at first age of sex. Fewer engaged in risky sexual behaviours when compared to domestic students. They also reported fewer sexual partners and higher condom usage. However, culture influenced the sexual behaviours and attitudes of international students; in particular, Asian female international students, who tested risk-taking behaviours, such as casual sex, in more liberal Western countries. Appropriate intervention and further education are needed to decrease international students’ sexual health risks.
Ultrafast dynamical charge-lattice coupling in rare-earth nickelate thin films studied by time-resolved terahertz spectroscopy

Published: February 2022

Abstract
Rare-earth nickelates exhibit a rich phase diagram formed by the complex interplay of intertwined and competing energetics of fundamental entities. To unwind the coupling and interaction mechanisms of fundamental entities underneath, time-resolved terahertz (THz) spectroscopy was implemented to understand non-equilibrium carrier and lattice dynamics of epitaxial thin films of La
x
Eu1−x
NiO3 (x = 0, 0.25, 0.50, 1) systems, where x = 0 is insulating while remaining are metallic at room temperature. The THz transmittance of the insulating and metallic phases exhibit contrasting photo-induced phases associated with bi-exponential and mono-exponential relaxation mechanisms, respectively. A pronounced oscillatory feature superimposed on the mono-exponential relaxation manifests only in the metallic phase. As ascribed to the acoustic phonons, the ‘x’ dependent behavior of this feature reveals an inverse relation between the strength of electron–phonon coupling and the magnitude of conductivity. In the insulating state, in contrast, the relaxation time constants are associated with the recovery of charge-ordering and electron–phonon thermalization. This dynamical lattice–charge interaction study demonstrates use of this ultrafast phenomena in nickelate thin films in new generation ultrafast photo-acoustic devices as an alternate to conventional surface acoustic wave device.

Abstract
Partially depleted silicon-on-insulator (PDSOI) MOSFETs are widely used in 225 °C high-temperature electronic system applications with integrated circuits. But the process node stays at 0.5 µm for a long time and no further breakthrough can be achieved. This paper reports the high-temperature characteristics of 28 nm ultra-thin body and box fully depleted SOI (FDSOI) CMOS transistors with low threshold voltage (LVT) structure. Experimental results demonstrate that V
t shift changes with temperature as low as 0.59 mV °C−1, the subthreshold slope (SS) is 145.35 mV dec−1 at 300 °C, and the related parameters are optimized by 3.7 times and 2.2 times respectively compared with 0.13 µm PDSOI. Combined with theoretical analysis, it is proved that the ultra-body FDSOI has an LVT drift rate and better SS than 0.13 µm PDSOI at high temperature. The advantage of this performance is mainly due to the difference between

VT and β
VT coefficients related to the back gate effect. Under negative back-gate bias, the I

off ratio can be increased by two orders of magnitude without affecting V

Superconducting pancake coil FEM analysis for very low frequency levitated gravity accelerometers

Published: February 2022

Abstract
State-of-the-art detectors are necessary to measure very tiny variations of gravity produced by spiraling neutron stars, merging black holes and moving tectonic plates. We are developing a superconducting gravity gradiometer and aim to achieve 0.1 mE Hz−1/2 (1 E ≡ 10–9 s–2) in the frequency band of 0.1 mHz to 0.1 Hz. The superconducting test masses are levitated by a superconducting current-carrying monolayer pancake coil, which is one of the key components of the instrument. However, the nonlinear aspect of the pancake coil inductance with respect to the coil to test mass separation imposes one of the main constraints to achieve such sensitivity at low frequencies. In this paper, we investigate the causes of that nonlinearity by finite element method using COMSOL Multiphysics® simulation software. Inductances were measured with an experimental setup where a gap spacing, created by a pancake coil and a niobium plate, could be adjusted. The inductances computed with a 2D axis-symmetric model satisfactorily agreed with the experimental data. We extensively studied several mechanisms for cancelling the nonlinearity of the inductance. A solenoid next to the pancake coil is possibly the most effective and practical way to mitigate it. Our approach may also be useful for obtaining a simple and effective model to study magnetostatic problems in a superconductor.
Towards the establishment of the light J

Published: February 2022

Abstract
The observation of the light hybrid candidate

by the BESIII Collaboration offers great opportunities for advancing our knowledge on exotic hadrons in terms of flavor sector. We demonstrate that this observation provides a crucial clue for establishing the

hybrid nonet. Based on the flux tube model picture, the production and decay mechanisms for the

hybrid nonet in the

radiative decays into two pseudoscalar mesons are investigated. In the

sector, we deduce that the SU(3) flavor octet and singlet mixing is non-negligible and apparently deviates from the flavor ideal mixing. Because only signals for one isoscalar

are observed in the

channel, we investigate two schemes of the nonet structure in which

can either be the higher or lower mass state that strongly couples to

. Possible channels for detecting the multiplets are suggested. In particular, a combined analysis of the hybrid production in

, where

and

denote the light vector mesons and

hybrid states, respectively, may provide further evidence for this nonet structure and ultimately establish these mysterious exotic species in the experiment.
The Response of the Earth’s Lower Ionosphere to Gamma-Ray Solar Flares and their Associated X-ray
Authors: Mohery Mahmoud , Farid Hussein M. , Ali Alaa 
Published: February 2022

Abstract
The present work aims to explore the impact of solar gamma-ray flares (GRFs), detected by the Fermi-Large Area Telescope (LAT), and their associated X-ray flares (XRFs) on the Earth’s lower ionosphere. The data of ionospheric parameter fmin were collected from the Yamagawa mid-latitude ionosonde station in Japan. Because most of the GRFs used in this study are associated with soft X-ray (SXR) emissions, detected by the Geostationary Operational Environmental Satellite (GOES), we classified them into three types: simultaneous (S), delayed (D) and not associated (N), reflecting the phase occurrence of the solar flares. Generally, the ionospheric D layer responds strongly to XRFs more than GRFs. The temporal profiles of the ionospheric parameter fmin show distinct behaviors as a response to the various GRF types. In the case of the S-type, a single strong peak, with an average value of 5.2 MHz, emanates in the fmin profile within an average interval of time of less than half an hour. In the case of the D-type, two successive peaks appear in the fmin profile, with an average value of 6.0 MHz for the second peak through a time interval of one hour after the onset of gamma-ray (GR) emissions. The response of the fmin parameter to the N-type flares appears as a single peak with an average value of 4.8 MHz within about an hour. We notice that the difference between the fmin peak values and the corresponding reference ones (dfmin) is more convenient and representative than the fmin values, where the median GR flux of the S-, D- and N-types tends to increase as the average dfmin increases.
An energetic approach to model the relationship between tire rolling friction and road surface macrotexture
Authors: Riahi Ebrahim , Do Minh-Tan , Kane Malal 
Published: February 2022

Abstract
To investigate the relationship between tire rolling friction and road surface texture, a model based on the energy dissipated by a rubber block when it is deformed cyclically by road surface asperities is proposed. The effects of speed and temperature are considered using time-temperature superposition and the Williams-Landel-Ferry equations. The model is applied to texture profiles, measured using a laser profilometer, and filtered to simulate the envelopment of road surfaces by a tire, to estimate the dissipated energy and deduce the coefficient of rolling friction. The comparison between the model and the experiments, obtained by measurements performed on road samples in the laboratory, shows a fair correlation between the predicted and measured coefficients of rolling friction, this depending on the type of surface studied. Discussions are made to explain the gap between the model and the experiments and identify perspectives for future investigations.
Synthesis of a Zn/Fe–N–C electrocatalyst towards efficient oxygen reduction reaction via a facile one-pot method
Authors: Zhang Xiangkun , Li Yun , Ren Jingru , Huang Yongmin 
Published: February 2022

Abstract
The high price and unsatisfactory stability of Pt-based catalysts for the sluggish oxygen reduction reaction (ORR) severely limit the development of fuel cells and metal-air batteries. Therefore, developing Pt-free electrocatalysts with excellent activities and stabilities is significant. Herein, an efficient Zn/Fe–N–C electrocatalyst is synthesized via a facile one-pot method. Owing to its curved nanosheet structure, appropriate microporous and mesoporous specific surface areas, abundant defects and high Fe–Nx content, Zn/Fe–N–C exhibits remarkable ORR activity and stability in alkaline electrolyte. Its half-wave potential is 0.843 V, which is 10 mV higher than that of Pt/C. Moreover, Zn/Fe–N–C also manifests satisfactory performance in a practical Zn-air battery. Its maximum output power density is 108.5 mW cm−2, which is equivalent to that of Pt/C. In this work, a simple synthesis method for highly active ORR electrocatalyst is provided, which can be implemented for the future design and synthesis of electrocatalysts used in fuel cells and metal-air batteries.
