Scalability of non-adiabatic effects in lithium-decorated graphene superconductor
Authors: Szcze¸śniak Dominik 
Published: April 2023

Abstract
The analysis is conducted to unveil how the non-adiabatic effects scale within the superconducting phase of lithium-decorated graphene

. Based on the Eliashberg formalism it is shown that the non-adiabatic effects notably reduce essential superconducting parameters in

and arise as a significant oppressor of the discussed phase. Moreover, non-adiabaticity is found to scale with the strength of superconductivity, proportionally to the phonon energy scale and inversely with respect to the electron-phonon coupling. These findings are partially in contrast to other theoretical studies and show that superconductivity in

is more peculiar than previously anticipated. In this context, the guidelines for enhancing superconducting phase in

and sibling materials are also proposed.

Published: April 2023

Abstract

Context
The level of evidence is low for the treatment of patients with dysthyroid optic neuropathy (DON) and there is no consensus on the treatment of DON with intravenous high-dose glucocorticoids (ivGC) or direct surgical decompression.

Objective
To compare the efficacy of glucocorticoid treatment and orbital decompression (OD) in DON.

Data Sources
PubMed, EMBASE, and Cochrane Library were searched along with other sources.

Study Selection
A total of 17 studies met the inclusion criteria.

Data Extraction
Standard methodological guidance of the Cochrane Handbook was used and data were independently extracted by multiple observers. The primary outcomes were the improvement of best corrected visual acuity (ΔBCVA). Secondary outcomes were proptosis reduction, change in diplopia, visual field defects, and intraocular pressure (IOP).

Data Synthesis
The ΔBCVA in the ivGC + OD group was improved 0.26 LogMAR more than in the ivGC group (P = .007). The ΔBCVA in the OD group was better than in the ivGC group (P = .008). Posttreatment proptosis in the ivGC + OD and OD groups were improved further by 3.54 mm and 3.00 mm, respectively, than in the ivGC group (P &lt; .01). The mean deviation (MD) in the ivGC + OD group was improved by an additional 5.33 dB than in the ivGC group (P = .002). The IOP in the ivGC + OD group was improved further than in the ivGC group (P = .03).

Conclusions
Based on the results of the present meta-analysis, OD or ivGC + OD may be more effective in improving BCVA and MD and reducing proptosis compared with ivGC. Compared with ivGC alone, ivGC + OD is more effective in improving IOP than ivGC. Although this study improves the hierarchy of evidence in the treatment of DON, additional randomized controlled trials are needed to confirm this conclusion.

BACKGROUND:
Ambulatory surgery centers (ASCs) have emerged as an alternative setting for surgical care as part of the national effort to lower health care costs. The literature regarding the safety of minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) in the ASC setting is limited to few small case series.

OBJECTIVE:
To assess the safety and efficacy of MIS TLIF performed in the ASC vs inpatient hospital setting.

METHODS:
A total of 775 patients prospectively enrolled in the Quality Outcomes Database undergoing single-level MIS TLIF at a single ASC (100) or the inpatient hospital setting (675) were compared. Propensity matching generated 200 patients for analysis (100 per cohort). Demographic data, resource utilization, patient-reported outcome measures (PROMs), and patient satisfaction were assessed.

RESULTS:
There were no significant differences regarding baseline demographic data, clinical history, or comorbidities after propensity matching. Only 1 patient required inpatient transfer from the ASC because of intractable pain. All other patients were discharged home within 23 hours of surgery. The rates of 90-day readmission (2.0%) and reoperation (0%) were equivalent between groups. Both groups experienced significant improvements in all PROMs (Oswestry Disability Index, EuroQol-5D, back pain, and leg pain) at 3 months that were maintained at 1 year. PROMs did not differ between groups at any time point. Patient satisfaction was similar between groups at 3 and 12 months after surgery.

CONCLUSION:
In carefully selected patients, MIS TLIF may be performed safely in the ASC setting with no statistically significant difference in safety or efficacy in comparison with the inpatient setting.

Published: April 2023

Objectives: To determine whether radiomics data can predict local tumor progression (LTP) following radiofrequency ablation (RFA) of colorectal cancer (CRC) lung metastases on the first revaluation chest CT. Methods: This case–control single-center retrospective study included 95 distinct lung metastases treated by RFA (in 39 patients, median age: 63.1 years) with a contrast-enhanced CT-scan performed 3 months after RFA. Forty-eight radiomics features (RFs) were extracted from the 3D-segmentation of the ablation zone. Several supervised machine-learning algorithms were trained in 10-fold cross-validation on reproducible RFs to predict LTP, with/without denoising CT-scans. An unsupervised classification based on reproducible RFs was built with k-means algorithm. Results: There were 20/95 (26.7%) relapses within a median delay of 10 months. The best model was a stepwise logistic regression on raw CT-scans. Its cross-validated performances were: AUROC = 0.72 (0.58–0.86), area under the Precision-Recall curve (AUPRC) = 0.44. Cross-validated balanced-accuracy, sensitivity and specificity were 0.59, 0.25 and 0.93, respectively, using p = 0.5 to dichotomize the model predicted probabilities (vs 0.71, 0.70 and 0.72, respectively using p = 0.188 according to Youden index). The unsupervised approach identified two clusters, which were not associated with LTP (p = 0.8211) but with the occurrence of per-RFA intra-alveolar hemorrhage, post-RFA cavitations and fistulizations (p = 0.0150). Conclusion: Predictive models using RFs from the post-RFA ablation zone on the first revaluation CT-scan of CRC lung metastases seemed moderately informative regarding the occurrence of LTP. Advances in knowledge: Radiomics approach on interventional radiology data is feasible. However, patterns of heterogeneity detected with RFs on early re-evaluation CT-scans seem biased by different healing processes following benign RFA complications.

Objective: To evaluate correlation between contrast-enhanced ultrasonography Liver Imaging Reporting and Data System (CEUS LI-RADS; v. 2017) categories (LR 3–5 vs LR-M) and outcomes in patients with early-stage hepatocellular carcinoma (HCC) after initial therapy. Methods: In this retrospective study, 272 patients with high risks for HCC and solitary clinically or pathologically confirmed HCC were identified between January 2010 and December 2015. Patients were initially treated by resection and radiofrequency ablation (RFA) according to the Barcelona Clinic Liver Cancer staging system and were followed up until December 31, 2018. Recurrence-free survival (RFS) and overall survival (OS) were compared between nodules assigned as LR 3–5 or LR M according to CEUS LI-RADS v. 2017 by using the Kaplan-Meier curve, log-rank test, and Cox proportional hazard model. Results: Early washout is the key determinating whether a nodule is classed as LR-M. Treatment procedures and LI-RADS category showed an independent correlation with OS and RFS (p < 0.05). LR 3–5 category were more correlated with better OS (88.6 months and 74.2 months, respectively; p = 0.017) compared with LR-M. Surgical resection demonstrated longer OS and RFS than RFA in LR-M patients and longer OS in LR 3–5 patients (p < 0.05). Besides, there was no significantly difference in OS and RFS between two categories in resection (p > 0.05), while for patients treated with RFA, LR 3–5 patients showed significant longer OS and RFS than LR-M patients (p < 0.05). Conclusion: Patients with HCC assigned as LR-M showed worse RFS and OS and surgical resection tended to be a more effective treatment for these patients. Advances in knowledge: Putting forward a theory that CEUS LI-RADS categories could independently predict the outcome for patients with solitary HCC at early-stage after initial treatment.

Published: April 2023

Objective: To evaluate the diagnostic accuracy of MRI-hysterosalpingogram (HSG) with semiquantitative dynamic contrast‐enhanced perfusion, against the virtual multislice CT hysterosalpingogram (VHSG) as a reference standard. Methods and Materials: In this prospective study, 26 women (age >18 years) searching for infertility causes and with VHSG physician request. Thereafter, the assessment performance of both techniques was determined by two reader analyses. k statistics were used for the assessment of tubal patency. Receiver operating characteristic (ROC) analysis was used to compare the capability for tubal patency assessment between both exams on a per-patient and per-tube basis. The McNemar test was used to compare the diagnostic accuracy measures. Results: Tubal patency, uterine morphological, ovarian, and extrauterine abnormalities were evaluated through both exams in all 26 women. There was no significant difference between diagnostic performance measurements between the methods. The ROC curve of VHSG was 0.852 for both per-patient and per-tube analyses, and one and 0.938 for MRI-HSG. Sensitivity and specificity for per-patient and per-tube for VHSG were 95.2 and 97.7, 80 and 87.5%, and for MRI-HSG 100% for both analyses and 100 and 87.5%, respectively. Conclusion: This study demonstrates the feasibility of diagnosing tubal patency through MRI, using a semi-quantitative dynamic contrast‐enhanced perfusion sequence, and the satisfactory diagnosing of the uterine morphology, ovarian abnormalities, and ovarian and deep endometriosis. Advances in knowledge: Multiparametric MRI with a perfusion real-time sequence as a HSG method can be used in the evaluation not only for uterine and ovarian abnormilities but also tubal patency.
Sample-Driven Optimal Stopping: From the Secretary Problem to the i.i.d. Prophet Inequality
Authors: Correa José , Cristi Andrés , Epstein Boris , Soto José A. 
Published: April 2023

We take a unifying approach to single selection optimal stopping problems with random arrival order and independent sampling of items. In the problem we consider, a decision maker (DM) initially gets to sample each of N items independently with probability p, and can observe the relative rankings of these sampled items. Then, the DM faces the remaining items in an online fashion, observing the relative rankings of all revealed items. While scanning the sequence the DM makes irrevocable stop/continue decisions and her reward for stopping the sequence facing the item with rank i is Yi. The goal of the DM is to maximize her reward. We start by studying the case in which the values Yi are known to the DM, and then move to the case in which these values are adversarial. For the former case we are able to recover several classic results in the area, thus giving a unifying framework for single selection optimal stopping. For the latter, we pin down the optimal algorithm, obtaining the optimal competitive ratios for all values of p.

Published: April 2023

AimsThe goal was to evaluate tibiofemoral knee joint kinematics during stair descent, by simulating the full stair descent motion in vitro. The knee joint kinematics were evaluated for two types of knee implants: bi-cruciate retaining and bi-cruciate stabilized. It was hypothesized that the bi-cruciate retaining implant better approximates native kinematics.MethodsThe in vitro study included 20 specimens which were tested during a full stair descent with physiological muscle forces in a dynamic knee rig. Laxity envelopes were measured by applying external loading conditions in varus/valgus and internal/external direction.ResultsThe laxity results show that both implants are capable of mimicking the native internal/external-laxity during the controlled lowering phase. The kinematic results show that the bi-cruciate retaining implant tends to approximate the native condition better compared to bi-cruciate stabilized implant. This is valid for the internal/external rotation and the anteroposterior translation during all phases of the stair descent, and for the compression-distraction of the knee joint during swing and controlled lowering phase.ConclusionThe results show a better approximation of the native kinematics by the bi-cruciate retaining knee implant compared to the bi-cruciate stabilized knee implant for internal/external rotation and anteroposterior translation. Whether this will result in better patient outcomes remains to be investigated.Cite this article: Bone Joint Res 2023;12(4):285–293.
Broadband adiabatic mode division (de)multiplexer in thin film lithium niobate

Published: April 2023

We report a broadband adiabatic mode division (de)multiplexer in a thin film lithium niobate (TFLN) waveguide based on the stimulated Raman adiabatic passage scheme. This particular adiabatic tunneling process is implemented in a three-waveguide structure, in which the intermediate waveguide is tilted relative to the outer waveguides. The excitation of the intermediate waveguide is negligible during the mode (de)multiplexing. A taper structure is included in the intermediate waveguide to ensure efficient mode conversion. The proposed (de)multiplexer can realize multiplexing or demultiplexing of the modes TE0, TE1, and TE2. The structural parameters are determined by simulation, and the results show that conversion efficiencies of 96.3% and 94.6% can be obtained for TE2 and TE1, while the 1-dB operation bandwidth is around 420 nm. The cross talks of TE2, TE1, and TE0 are lower than −13.4dB, −16.4dB, and −34.2dB. The designed (de)multiplexer has relatively good fabrication tolerance. Therefore, it is suitable in TFLN integrated chips.

AbstractThe purpose of this study was to investigate the effects of loading conditions and left ventricular (LV) contractility on mitral annular dynamics. In 10 anesthetized pigs, eight piezoelectric transducers were implanted equidistantly around the mitral annulus. High‐fidelity catheters measured left ventricular pressures and the slope of the end‐systolic pressure‐volume relationship (Ees) determined LV contractility. Adjustments of pre‐ and afterload were done by constriction of the inferior caval vein and occlusion of the descending aorta. Mitral annulus area indexed to body surface area (MAAi), annular circularity index (ACI), and non‐planarity angle (NPA) were calculated by computational analysis. MAAi was more dynamic in response to loading interventions than ACI and NPA. However, MAAi maximal cyclical reduction (−Δr) and average deformational velocity (−) did not change accordingly (p = 0.31 and p = 0.22). Reduced Ees was associated to attenuation in MAAi‐Δr and MAAi‐ (r2 = 0.744; p = 0.001 and r2 = 0.467; p = 0.029). In conclusion, increased cardiac load and reduced LV contractility may cause deterioration of mitral annular dynamics, likely impairing coaptation and increasing susceptibility to valvular incompetence.
Love-Hate and War: Perfectionism and Self-Overcoming in Thus Spoke Zarathustra
Authors: Siemens Herman W. 
Published: April 2023

Abstract
This essay investigates the thought of self-overcoming (Selbst-Überwindung, sich überwinden) in Thus Spoke Zarathustra, and its relation to Nietzsche’s Emersonian perfectionism in Schopenhauer as Educator. It is a conceptual study focused on key passages on self-overcoming in Zarathustra and related problems – most notably how to combine the demand for boundless affirmation with the demand for total critique in Nietzsche’s project of critical transvaluation. The main thesis is that Zarathustra’s response depends on his addressees: with regard to the mob, the rabble or Gesindel, he advocates a limit in negation under the sign of mildness (Milde); with regard to others engaged in self-overcoming, he advocates a limited negation in the form of love-hate. Connections with the perfectionism of Schopenhauer as Educator are made throughout the essay, which then draws them together in a comparative analysis of self-overcoming in Zarathustra and Nietzsche’s untimely perfectionism. The essay closes with some methodological reflections on the risks and benefits of its “prismatic” approach, focused on key passages in relation to other works in abstraction from the overall composition and narrative of the book.
Does the patellar tendon reflex affect the postural stability in stroke patients with blocked vision?
Authors: Zhou Ziyou , Hu Zhen , Bao Wei , Yang Ying , Chen Kai 
Published: April 2023

Abstract

Background
Stroke patients often show postural instability. The patellar tendon reflex is a basic physical examination for stroke patients. This study aimed to explore the correlation between patellar tendon reflex grade and postural stability among stroke patients.

Methods
A total of 37 elderly stroke patients, each with the same quadriceps muscle strength but different patellar tendon reflex levels, were tested on a force platform under eyes-open (EO) and eyes-closed (EC) conditions. Parametric analysis, detrended fluctuation analysis (DFA), and power spectral density (PSD) analysis were used in centre of pressure (COP) signal processing. The correlation between the results of measured data processing and the level of patellar tendon reflex was analysed.

Results
All three parameters of COP (the length of the sway trajectory, the mean range of the sway trajectory in the mediolateral [ML] direction [R

x
], and the mean range of the sway trajectory in the anterior–posterior [AP] directions [R

y
]) were negatively correlated with the patient’s patellar tendon reflex grade under the EC condition. The DFA results showed that a higher grade of patellar tendon reflex was associated with a smaller value of the crossover point in the AP direction. Only the PSD values of each frequency band in the AP direction were negatively correlated with patellar tendon reflex grade with EO and became negatively correlated in both AP and ML directions with EC. Overall, the results showed a strong correlation between patellar tendon reflex and postural stability in stroke patients when vision was blocked.

Significance
The strong correlation with EC may provide insights into clinic evaluation and treatment for rehabilitation or fall risks of stroke patients.
Exfoliated g-C3N4 as efficient sorbent for Pb ions removal from synthetic wastewaters
Authors: Modwi Abueliz 
Published: April 2023

Abstract
A successful exfoliation of g-C3N4 was achieved via ultrasonic power and ethanol as a solvent. The untreated (CN1) and treated (CN2) samples were characterized using various techniques. The X-ray diffraction (XRD) ascertained the formation of a typical nitride entity with less intense peaks for the ultra-sonicated sample. The FTIR, EDX, and XPS data have jointly confirmed the formation of the target compound. By virtue of its enhanced BET surface area (277 m2 g−1) the treated samples could effectively adsorb 278 mg g−1 of Pb (II) in a considerably short time of 47 min. The adsorption phenomenon was found to abide with the second‵ order kinetics and adopt a Langmuir isotherm behavior. Lead (II) elimination showed high removal efficiency after up to four cycles of effective recycling. This study demonstrated that CN2 nanosheets might be approved as an effective and stable candidate for eliminating dangerous heavy metal pollutants.

Abstract
Für diesen Beitrag werden Eisen-Graphit-Verbundwerkstoffe (EGr) mit verschiedenen Graphitgehalten (zwischen 0 und 80 %) durch pulvermetallurgische Verfahren hergestellt und charakterisiert. Diese Proben kommen als Beilagen in einer Vorschubachse mit Linearführung zum Einsatz, und die resultierende Dämpfungswirkung wird in der Maschinenbaugruppe durch Kurzzeit-Fourier-Transformation (SFTF) und Fast-Fourier-Transformation (FFT) analysiert. Mit steigendem Graphitgehalt erhöht sich die Materialdämpfung des EGr. Das Gesamtsystem zeigt jedoch beim Einsatz eines EGr mit 20 Prozent Graphit das beste Dämpfungsverhalten.
