Although most patients who undergo transforaminal lumbar interbody fusion (TLIF) show favorable surgical results, some still have unfavorable results for various reasons. This study aimed to investigate the influence of differences in lumbar lordosis (LL) between the standing and supine positions (DiLL: supine LL–standing LL) on minimum 5-year surgical outcomes after short-segment TLIF. Ninety-one patients with lumbar degenerative disease who underwent short-segment TLIF (1–2 levels) were categorized based on preoperative differences in LL as DiLL (+) and DiLL (−). Comparison and correlation analyses were performed. The incidence of adjacent segment disease (ASD) by radiology (R-ASD) and symptomatic ASD (S-ASD), bony fusion rates, and pre- and postoperative clinical scores (visual analog scale [VAS]; Japanese Orthopaedic Association [JOA] score; Oswestry disability index (ODI); and Nakai’s score) were evaluated. Postoperatively, VAS for low back pain (LBP) in the sitting position, JOA scores for LBP, lower leg pain, intermittent claudication, ODI, and Nakai’s score were significantly worse in the DiLL (+) group than in the DiLL (−) group. DiLL values were significantly correlated with VAS for LBP, ODI, and Nakai’s score, postoperatively. Positive DiLL values were associated with poorer postoperative outcomes. DiLL is a simple and useful method for predicting mid-term outcomes after TLIF.

Published: August 2022

We aimed to evaluate the radiographic and clinical outcomes after gamma knife radiosurgery (GKRS) for trigeminal schwannomas (TSs). A total of 87 patients who underwent GKRS for TSs between 1990 and 2020 were enrolled. The mean tumor volume was 4.3 cm3. The median prescribed dose for the margins of the tumor was 13 Gy. The median follow-up duration was 64.3 months (range 12.0–311.5 months). The overall local tumor control rate was 90%, and the symptom response rate was 93%. The response rate for each symptom was 88% for facial pain, 97% for facial sensory change, and 86% for cranial nerve deficits. Nineteen (22%) patients showed transient swelling, which had regressed at the time of the last follow-up. Cystic tumors were associated with transient swelling (p = 0.04). A tumor volume of < 2.7 cm3 was associated with local tumor control in univariable analysis. Transient swelling was associated with symptom control failure in both univariable and multivariable analyses (p = 0.04, odds ratio 14.538). GKRS is an effective treatment for TSs, both for local control and symptom control.

Published: August 2022

The release of unspent dyes from industries constitutes hazard and environmental challenges. For rapid and efficient removal of Congo red from aqueous solutions, a composite was prepared from coconut husk, raw clay, Fe(II) and Fe(II) compounds. Adsorption variables (initial pH of the solution, contact time, temperature and initial concentration of Congo red) were varied to understand the characteristics and mechanisms of the adsorption process. The composite was characterised using Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM)–Energy dispersive X-ray (EDX) spectroscopy, nitrogen adsorption–desorption isotherm, X-ray Diffraction (XRD) spectroscopy and pH of the point zero charge (pHpzc). The optimal values of the pH, equilibrium time and temperature for adsorption of Congo red by the composite are 2, 40 min and 50 °C, respectively. The kinetic and equilibrium data followed Avrami fractional order and Langmuir models, respectively. A 1.0 g of the composite could maximally take up 1649.3 mg of Congo red at 50 °C. The values of ΔG° are in the range of − 27.901 to − 24.492 kJ mol–1 while the value of ΔH° is − 72.239 kJ mol–1. Hence, the removal of the Congo red by the composite was spontaneous, feasible and exothermic. The adsorption process was biphasic and followed physisorption process. Electrostatic interaction played a significant role in the removal of Congo red by the composite. The combine data in this study have proven that the clay composite, a cheap adsorbent, can be used for remediation of water contaminated with Congo red.

Magnetocardiography is a contactless imaging modality for electric current propagation in the cardiovascular system. Although conventional sensors provide sufficiently high sensitivity, their spatial resolution is limited to a centimetre-scale, which is inadequate for revealing the intra-cardiac electrodynamics such as rotational waves associated with ventricular arrhythmias. Here, we demonstrate invasive magnetocardiography of living rats at a millimetre-scale using a quantum sensor based on nitrogen-vacancy centres in diamond. The acquired magnetic images indicate that the cardiac signal source is well explained by vertically distributed current dipoles, pointing from the right atrium base via the Purkinje fibre bundle to the left ventricular apex. We also find that this observation is consistent with and complementary to an alternative picture of electric current density distribution calculated with a stream function method. Our technique will enable the study of the origin and progression of various cardiac arrhythmias, including flutter, fibrillation, and tachycardia.

Anomaly recognition method of perception system for autonomous vehicles based on distance metric
Authors: Shao Cuiping , Chen Beizhang , Miao Zujia , Cui Yunduan , Li Huiyun
Published: August 2022

Environmental perception system is the premise of the safety and stability of the autonomous vehicle system. However, studies have shown that the on‐board sensors included in the perception system are extremely vulnerable to external attacks and interference, leading to incorrect driving strategies and bringing great security threats. Aiming at the problem, this paper divides the vehicle‐mounted sensors into a positioning group and an identification group according to their role in the perception system. Then, based on the information correlation between sensors in the same group and the information correlation of a single sensor on adjacent time series, the distance metric model between sensors in a group and the distance metric model for each sensor of this group on time series is established. And the normal distance intervals corresponding to the confidence interval are calculated respectively. According to the distance metric model between sensors, the authors can detect anomalies in the perception system in real time. Further, according to the distance metric model for each sensor on adjacent time series, the authors can identify anomaly sensors. The authors’ experimental results quantitatively show that the method achieves real‐time anomaly recognition, and demonstrate the effectiveness and robustness of the method on the open‐source Karlsruhe institute of technology and toyota technological institute (KITTI) dataset.
Evaluation of patella height in native knees and arthroplasty: an instructional review
Authors: Konrads Christian , Schreiner Anna J. , Cober Simone , Schüll Daniel , Ahmad Sufian S. , Alshrouf Mohammad A.
Published: August 2022

Total knee arthroplasty (TKA) is the gold standard for treating advanced knee osteoarthritis. Among the postoperative complications of TKA are true patella infera (TPI) and pseudo patella infera (PPI), which should be differentiated since TPI exhibits significantly worse clinical outcomes. Multiple radiological patella height indices (PHI) exist; some were modified or originally designed for knees with implanted endoprostheses. However, there is no consensus on measuring and comparing patella height. Due to the lack of established, simple, reliable, and reproducible concepts for assessing patella height for arthroplasty, measuring patella height and the change of patella height by or after TKA have been challenging tasks for clinicians and researchers. This is a review of the current literature on methods for measuring patella height, with special attention to the ability to differentiate between the TPI and PPI after TKA. All literature on the topic was retrieved, and references from relevant articles were investigated until the end of April 2022.

Audit on Sepsis Management
Authors: Varghese Jerin Mathew
Published: August 2022

Aim

The aim of this study was to assess the compliance of sepsis management as per standard guidelines and intervention as per surviving sepsis criteria hour bundle and to assess bedside screening for sepsis by comparative analysis of two standard methods (systemic inflammatory response syndrome [SIRS] and quick sequential organ failure assessment [qSOFA]).

Methodology

A single-center review on 53 patients conceded through emergency department (ED) with sepsis as a finding during the period from July 2020 to December 2020. A benchmark group was utilized for relative investigation. Significant information was collected for examination from the electronic records and from the clinical records.

Results

ED showed great consistency in triaging septic patients and in starting time-basic administration of patients whenever sepsis is perceived. The SIRS rules ordered 39 patients as septic with 73.5% affectability and particularity of 66%, while qSOFA characterized just five patients as septic with 9.3% affectability and explicitness of 92%.

Conclusion

The ED had great consistency in triaging patients by recording their vitals and mental status.

Intercession of patients with sepsis acknowledgment, for example, estimating introductory lactate levels, getting blood culture and sensitivity, administrating intravenous (IV) antimicrobials, IV liquids, and vasopressors when required and once again estimating lactate showed consistency according to standard rules

In view of the review investigation of septic patients, qSOFA performs ineffectively in contrast with SIRS as an underlying indicative instrument for patients introduced to ED who might have sepsis.

In this article, we report the case of a child with a rectourethral prostatic fistula, who had a Peña's descending colostomy with distal mucous fistula in the neonatal period and a posterior sagittal anorectoplasty at 6 months of life. The ARM repair was guided by indocyanine green (ICG), which was intravenously administered to evaluate the blood flow of the intestinal pull-through using the EleVision IR system (Medtronic Ltd, U.K.). ICG-based fluorescence-guided surgery helped to define the proximal resection margin, impacting intraoperative decision making, and no postoperative complications occurred.

We envisage that this technology will become part of the armory of pediatric surgeons soon, by reducing the risk of intra- and postoperative complications.

Published: August 2022

Background The global population is being plagued by several diseases and health conditions, and this calls for the need to adopt a strategy to enable people from all socioeconomic backgrounds to have the freedom and choice to opt for a medical profession as their career. The purpose of the current review is to explore the reasons which make medical education expensive and identify the strategies by which the cost of medical education can be minimized.

Methods An extensive search of all materials related to the topic was performed on the PubMed search engine and web site of the National Medical Commission. Relevant research articles focusing on costs in medical education published in the period 2005 to 2021 were included in the review. A total of 37 articles were selected based on their suitability with the current review objectives and analyzed. Keywords used in the search include medical education and cost in the title alone only.

Results We have to accept the fact that medical education is quite expensive and that's not the case with one nation but the trend is worldwide. It is the need of the hour to plan and implement strategies that make medical training accessible and available to people from all socioeconomic classes and regardless of other variables.

Conclusion In conclusion, the process of training medical students is expensive and accounts for a wide range of impacts on the medical aspirants. Thus, there is an indispensable need for the policy makers and the concerned stakeholders to join their hands together and take appropriate steps to minimize the overall cost of medical training, and thereby making it affordable to everyone.
Imaging Features of Soft Tissue Tumor Mimickers: A Pictorial Essay
Authors: Bhangle Devanshi S. , Sun Kevin , Wu Jim S.
Published: August 2022

Soft tissue lesions are commonly encountered and imaging is an important diagnostic step in the diagnosis and management of these lesions. While some of these lesions are true neoplasms, others are not. These soft tissue tumor mimickers can be due to a variety of conditions including traumatic, iatrogenic, inflammatory/reactive, infection, vascular, and variant anatomy. It is important for the radiologist and clinician to be aware of these common soft tissue tumor mimickers and their characteristic imaging features to avoid unnecessary workup and provide the best treatment outcome.

Predicting and modeling the behavior of experiments with radiation waves propagating through low-density foams require a detailed quantification of the numerous uncertainties present. In regimes where a prominent radiative shock is produced, key dynamical features include the shock position, temperature, and curvature and the spatial distribution and temperature of the corresponding supersonic radiation wave. The COAX experimental platform is designed to constrain numerical models of such a radiative shock propagating through a low-density foam by employing radiography for spatial and shock information, Dante for characterizing the x-ray flux from the indirectly driven target, and a novel spectral diagnostic designed to probe the temperature profile of the wave. In this work, we model COAX with parameterized 2D simulations and a Hohlraum-laser modeling package to study uncertainties in diagnosing the experiment. The inferred temperature profile of the COAX radiation transport experiments has been shown to differ from simulations more than expected from drive uncertainties that have been constrained by simultaneous soft x-ray flux and radiography measurements.
Understanding indium incorporation of InGaN grown on polar, semi-polar, and non-polar orientation by metal–organic vapor phase epitaxy
Authors: Hu Nan , Avit Geoffrey , Pristovsek Markus , Honda Yoshio , Amano Hiroshi
Published: August 2022

We studied indium incorporation into InGaN/GaN quantum wells grown by metal–organic vapor phase epitaxy by systematically varying of gallium and indium precursor flows on (0001), (101¯3), (112¯2), and (101¯0) orientations. The layer thickness and indium composition obtained from x-ray diffraction analysis were correlated with a model based on indium and gallium incorporation efficiencies. In the model, the indium incorporation efficiency is reproduced by the Langmuir surface coverage of gallium, indicating that indium atoms close to gallium atoms can be incorporated preferably.
Hierarchical foliation of one-dimensional Vlasov–Poisson system
Authors: Maekaku K. , Yoshida Z.
Published: August 2022

We elucidate the intermediate of the macroscopic fluid model and the microscopic kinetic model by studying the Poisson algebraic structure of the one-dimensional Vlasov–Poisson system. The water-bag model helps formulating the hierarchy of sub-algebras, which interpolates the gap between the fluid and kinetic models. By analyzing the embedding of the sub-manifold of an intermediate hierarchy in a more microscopic hierarchy, we characterize the microscopic effect as the symmetry breaking pertinent to a macroscopic invariant.

Published: August 2022

An approach to numerically modeling relativistic magnetrons, in which the electrons are represented with a relativistic fluid, is described. A principal effect in the operation of a magnetron is space-charge-limited (SCL) emission of electrons from the cathode. We have developed an approximate SCL emission boundary condition for the fluid electron model. This boundary condition prescribes the flux of electrons as a function of the normal component of the electric field on the boundary. We show the results of a benchmarking activity that applies the fluid SCL boundary condition to the one-dimensional Child–Langmuir diode problem and a canonical two-dimensional diode problem. Simulation results for a two-dimensional A6 magnetron are then presented. Computed bunching of the electron cloud occurs and coincides with significant microwave power generation. Numerical convergence of the solution is considered. Sharp gradients in the solution quantities at the diocotron resonance, spanning an interval of three to four grid cells in the most well-resolved case, are present and likely affect convergence.
Digital single-photon-avalanche-diode arrays for time-of-flight Thomson scattering diagnostics
Authors: Salzmann Hans , Nielsen Per , Gowers Chris
Published: August 2022

The collection optics of Thomson scattering systems for plasma devices are designed with maximum possible étendue to keep the required laser energy low. If the spatial resolution along the laser beam is performed by a time-of-flight method, then the detectors, in addition to a large sensitive area, must offer a high frequency bandwidth. Up until now, only microchannel-plate photomultipliers meet these requirements. Here, we investigate the potential use of digital avalanche photodiode arrays operated in the Geiger mode as alternative detectors. In this mode of operation, each array will serve as a fast, sensitive detector. The use of these detectors will lead to significant improvements of the Thomson scattering diagnostic. Most important of these will be a better spatial resolution, down to about 2 cm without deconvolution. Furthermore, the lifetime of the detectors will be increased; the detectors will cover the whole blue wing of the scattered spectrum when using a single wavelength laser, and this will enable measurements of electron temperature and density profiles at kHz repetition rates.

We report on the behavior of an acoustic phonon spectral linewidth of bulk single-crystalline Si1−xGex alloy with the x of 0.16, 0.32, and 0.45 in the phonon dispersion relation along the Γ–X ([00q]) direction. Broadening of both transverse acoustic (TA) and longitudinal acoustic (LA) modes of the bulk Si1−xGex alloy was directly observed using inelastic x-ray scattering (IXS) with increasing momentum (from Γ to X points in the Brillouin zone), which cannot be observed in pure Si or pure Ge. The IXS spectral linewidth of the TA mode indicated Ge dependence, which suggests the overlapping of a low-energy local vibration mode (LVM) caused by Ge clusters surrounded by Si atoms around the X point. Although the behavior of the IXS spectral linewidth of the LA mode showed almost no dependence on Ge fraction, the IXS spectra of the LA mode indicated broadening after crossing with a low-energy LVM with increasing momentum. The results obtained by molecular dynamics showed almost the same behavior of the acoustic phonon spectral linewidth. These results suggest that a change in the acoustic phonon spectral linewidth between the Γ and X points indicates a reduction in the acoustic phonon lifetime caused by the appearance of a localized mode originated from a random atom position in the alloy structure, leading to suppression of the thermal transport in the SiGe alloy.
Two-step seeding strategy in multiplex networks with inter-layer conversion cost of influence
Authors: Ni Chengzhang , Yang Jun
Published: August 2022

In this paper, we investigate the problem of influence seeding strategy in multilayer networks. In consideration of the fact that there exist inter-layer conversion costs associated with influence diffusion between layers in multiplex networks, a novel two-step seeding strategy is proposed to identify influential individuals in multiplex networks. The first step is to determine the target layer, and the second step is to identify the target seeds. Specifically, we first propose two comparable layer selection strategies, namely, multiplex betweenness centrality and multi-hop multiplex neighbors (MMNs), to determine the target layer of seeding diffusion and then construct a multiplex gravity centrality (MGC) in the manner of the gravity model to identify the influential seeds in the target layer. Subsequently, we employ a redefined independent cascade model to evaluate the effectiveness of our proposed seeding strategy by comparing it with other commonly used centrality indicators, which is validated on both synthetic and real-world network datasets. The experimental results indicate that our proposed seeding strategy can obtain greater influence coverage. In addition, parameter analysis of a neighborhood range demonstrates that MMN-based target layer selection is relatively robust, and a smaller value of a neighborhood range can enable MGC to achieve better influence performance.

Published: August 2022

As catechol (CC) is an industrial pollutant causing a health hazard, it is important to design for an efficient sensing device. Here, we investigate the possibility of using 2D VSe2 with transition metal (TM) decoration (TM = Pd, Ag, and Au) for effective sensing of CC by employing first principles simulations. The bonding mechanism of TM on VSe2 and interactions between CC and TM-decorated VSe2 have been investigated by the density of states, Bader charge, and the charge density distribution analysis. The TMs bind on VSe2 with the flow of charge from TM valence orbitals toward vacant orbitals of Se 4p, with significant binding energy. The binding of CC is due to the charge flow from O 2p orbitals of CC to TM-decorated VSe2. The clustering issues of TM have been addressed from diffusion energy barrier studies. The structural stability of substrate materials at ambient temperatures has been verified by ab-initio molecular dynamics simulations. CC binds with a binding energy of −0.949 eV to Pd-decorated VSe2 with a charge transfer of 0.0832 e from CC toward Pd. We strongly believe that Pd-decorated VSe2 is a highly promising material for CC sensing, and it may inspire experimental researchers to fabricate VSe2-based CC sensor devices.
