Analysis of quad-band polarization- and incident-angle independent low profile metamaterial absorber
Authors: Kaur Manpreet , Singh Hari Shankar 
Published: October 2022

Abstract
In this paper, a quad-band polarization- and incident-angle independent low-profile metamaterial absorber is proposed. The design consists of three square rings one into another and one plus-shaped slot structure. The size of the unit cell is 11 × 11 mm2 and is printed on an FR-4 substrate having a thickness of 1 mm. It provides 99.2%, 97.6%, 99.3%, and 99.9% absorption at 3.55 GHz, 5.27 GHz, 7.57 GHz, and 11.57 GHz, respectively, thus covering the S, C, and X bands. The surface current distribution of the proposed absorber is also shown at the four resonating frequencies to get a better insight into the design. Moreover, the stability of the proposed design is also validated with different incident angles (for both TE and TM modes) and polarization angles. In addition, a prototype of the proposed absorber structure is also fabricated and then verified experimentally.
Interlocked life cycles of counterfactual mood forms from Archaic to Classical Greek
Authors: Roi Ezra la 
Published: October 2022

Abstract
Based on a corpus study of 2074 occurrences in Archaic (424) and Classical (1650) Greek, I offer a unified explanation for the temporal reference extensions of counterfactual mood forms in declarative, interrogative, wish and de-activated illocutions (i.e. subordinate clauses). I propose a diachronic trajectory (life cycle) for counterfactual mood forms from past to present and future reference. Extensions are constrained diachronically by grammatical aspect (e.g. imperfect facilitating extensions to present reference more than the aorist or pluperfect), and actionality of the state of affairs in clausal context (atelic states of affairs enabling temporal extensions), as well as synchronically by illocutionary usage, collocations with temporal adverbs and common ground knowledge (i.e. temporal location known or not). This trajectory explains the replacements of the inherited counterfactual optative by the counterfactual indicative, because their life cycles are interlocked: in Archaic Greek the counterfactual optative had already extended from its original past to present and future reference and is losing its counterfactuality, whereas the counterfactual indicative referred only to the past and sometimes the present. In Classical Greek, temporal extensions of the counterfactual indicative are continued across different aspects, clause types and illocutions at different rates of change and the counterfactual optative is filtered out of the system.
Linguistic evidence for Kuṣāṇa trade routes
Authors: Schoubben Niels 
Published: October 2022

Abstract
Late Sanskrit lardayati ‘to load’ is probably not inherited from a PIE root *lerd-, as has recently been argued by Kaczyńska (2020), but can be explained as a denominative of *larda- ‘load, cargo’. This noun *larda- could be a borrowing from Bactrian *λιρτο /lirtə/ ‘load, cargo’ < Old Iranian *dr̥šta-. This etymology fits well with the fact that lardayati is phrased together with sthora- ‘pack-animal’, likely another instantiation of the Iranian collocation of *staura- ‘animal’ and *√darz- ‘to load’, for which I discuss evidence from Niya Prakrit, Parthian and Khotanese. In addition, further support is drawn from the independent historical evidence for the domination of the main trade routes of Central and South Asia by the Kuṣāṇa dynasty in the first centuries of our era.
Chebyshev wavelet-Picard technique for solving fractional nonlinear differential equations
Authors: Xu Xiaoyong , Zhou Fengying 
Published: October 2022

Abstract
In the present paper, an efficient method based on a new kind of Chebyshev wavelet together with Picard technique is developed for solving fractional nonlinear differential equations with initial and boundary conditions. The new orthonormal Chebyshev wavelet basis is constructed from a class of orthogonal polynomials called the fifth-kind Chebyshev polynomials. The convergence analysis and error estimation of the proposed Chebyshev wavelet expansion are studied. An exact formula for the Riemann-Liouville fractional integral of the Chebyshev wavelet is derived. Picard iteration is used to convert the fractional nonlinear differential equations into a fractional recurrence relation and then the proposed Chebyshev wavelet collocation method is applied on the converted problem. Several test problems are given to illustrate the performance and effectiveness of the proposed method and compared with the existing work in the literature.
A new numerical formulation for the generalized time-fractional Benjamin Bona Mohany Burgers’ equation
Authors: Chawla Reetika , Deswal Komal , Kumar Devendra 
Published: October 2022

Abstract
In this article, we present a novel numerical formulation for the generalized time-fractional Benjamin Bona Mohany Burgers’ (BBMB) equation using Atangana Baleanu Caputo (ABC) derivative. First, we apply a linearization technique to deal with the generalized non-linear expression, and then the Crank–Nicolson finite difference formula is used in the temporal direction. A reliable numerical technique is applied to discretize the time-fractional ABC derivative, and the central difference formulae are used to approximate the derivatives in the spatial direction. The method is shown unconditionally stable and second-order convergent in both directions through the Fourier analysis. The numerical results of two test problems are analyzed to validate the theoretical results.

Published: October 2022

Abstract

Objectives
The purpose of this study was to investigate the value of PET/CT in the preoperative staging of non-small cell lung cancer in predicting long-term survival and diagnostic performance, validated by histopathology following surgical resection.

Methods
Between 02/2009 and 08/2011, 255 patients with non-small cell lung cancer were included in this single-center prospective study. All underwent 18F FDG-PET/CT for pre-operative staging, and in 243 patients complete surgical resection was possible. Regarding lymph node involvement and extrathoracic metastases, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated using the histopathological staging as reference. Median follow-up for censored patients was 9.1 years.

Results
Overall 5-year survival rate of all patients was 55.6%, and of patients who had complete surgical resection it was 58.2%. In multivariate analysis of all surgically resected patients lymph node involvement (p=0.029) and age >61 years (p=<0.001) were significant independent prognostic factors. SUVmax and SUVmean cut-offs between SUV 2 and 11, however, were not associated with better or ;worse survival. The PET-CT sensitivity, specificity, positive predictive value and negative predictive value for predicting lymph node involvement were 57, 95, 88, and 76%, respectively. Furthermore, sensitivity, specificity, positive predictive value, and negative predictive value for detecting extrathoracic metastases were 100, 58, 98, and 100%, respectively.

Conclusions
In this study, tumor 18F FDG-uptake values did not provide additional prognostic information. Age>61 years and lymph node metastasis were associated with worse long-term survival in surgically resected patients. 18F FDG-PET/CT scans allow for improved patient selection. However, in staging mediastinal lymph nodes, there is a high rate of false positives and false negatives, suggesting that tissue biopsy is still indicated in many cases.

Published: October 2022

Abstract

Objectives
To assess the predictive value of pre-discharge heart rate variability (HRV) parameters in patients with acute coronary syndrome (ACS) treated by percutaneous coronary intervention (PCI).

Methods
145 consecutive male patients with ACS (aged 57.12 ± 10.81 years) were included in this study. Fifteen minutes electrocardiogram recording was done to measure time-domain [standard deviation of N–N intervals (SDNN), root-mean square differences of successive R–R intervals (rMSSD)] and frequency-domain [low-frequency (LF) power, high-frequency (HF) power and total power (TP)] HRV parameters before and after PCI. The primary end point was the occurrence of major clinical events (MCE) defined as death, sudden death or re-acute myocardial infarction at the end of 3 months follow-up.

Results
At a follow-up of 3 months, MCE occurred in 06 patients (4.14%) (Cardiac death was 3.01%, while that of sudden death was 1.13%). Out of six-MCE, four deaths and two re-AMIs occurred. Pre-discharge HRV values (SDNN, rMSSD, TP, LF and HF) were significantly lower in patients with ACS without MCE. Only total power HRV index (AUC=0.748; p=0.040) showed greater prognostic accuracy.

Conclusions
In conclusion, study showed an increase in SDNN, rMSSD, LF, HF and TP after successful revascularization with PCI in patients who had MCE. The resultant sensitivity, specificity of HRV is still limited in the present study. Particularly, its sensitivity is higher (33–83%) with a modest specificity (61–72%).

Published: October 2022

Abstract
This paper describes the design philosophy for our cloud-based virtual reality (VR) co-creation environment (CCE) for molecular modeling. Using interactive VR simulation can provide enhanced perspectives in molecular modeling for intuitive live demonstration and experimentation in the CCE. Then the use of the CCE can enhance knowledge creation by bringing people together to share and create ideas or knowledge that may not emerge otherwise. Our prototype CCE discussed here, which was developed to demonstrate our design philosophy, has already enabled multiple members to log in and touch virtual molecules running on a cloud server with no noticeable network latency via real-time artificial intelligence techniques. The CCE plays an essential role in the rational design of molecular robot parts, which consist of bio-molecules such as DNA and protein molecules.

Published: October 2022

Abstract
In this manuscript the plasmonic flower shaped silver nano dipole antenna is investigated on the silicon dioxide substrate for the optical wireless communication. The nano-circuit modeling of the proposed flower shaped nano dipole antenna is discussed which will enable the design of nano-photonic chips. The resonance tuning of the proposed flower shaped nano antenna is exhibited through end-to-end stacking of the flower cells over a petal of the nanostructure. The various possible structures were designed to tune the frequency in the range from 170 to 271 THz which covers 1550 nm window of the optical communication. The gap tuned flower shaped nano dipole antenna is designed by controlling the optical coupling of the waves in between two dipole arms of the nano-antenna. Further the detailed investigation on the performance of the flower shaped nano dipole antenna is executed through the design parameters such as gap of the nano dipole antenna feed G and radius of the flower cell R. The optimum nano-antenna characteristics which are suitable for the optical wireless communication are observed at the resonance frequencies such as 270, 284.5, 260.5, 226.5 and 209 THz with reflection coefficients −42.17, −42.42, −42.17, −45.20 and −50.33 dB respectively.

Published: October 2022

Abstract
Most Americans believe that higher education is heading in the wrong direction. In Lewis Carroll’s Alice’s Adventures in Wonderland, the eponymous heroine’s tumble into a rabbit hole immerses her in a bizarre, surreal, disorienting universe. Has higher education fallen down the rabbit hole? This paper will examine the many ways that academe has become a peculiar, illogical, and topsy-turvy world where things are often the opposite of what we call them and of what we expect them to be. To restore the credibility of our education system and make it of value to most students, it must be completely reimagined and, in fact, totally rebuilt from the ground up.

Published: October 2022

Abstract
The traditional method of deep pine in soda saline-alkali soil has great resistance, so the structure of the deep pine shovel is optimized to reduce the resistance. The deep pine shovel structure model was constructed with bionic technology, and the 3-D bionic model was built with Unigraphics software to imitate the appearance of the paw and toe of the Daurian typhus. The tip of the deep loose shovel imitates the surface structure of the lip base of the head of a dung beetle, which makes the tip of the shovel have good nonstick and wear resistance characteristics. The structural parameters, manufacturing materials, and technology of the spatula tip were determined, and the connection and fixation of the spatula tip and handle were completed by force analysis of the spatula tip and handle. In order to verify the drag reduction effect of the proposed method, a comparative experiment was designed. The experimental results show that the resistance of the designed deep pine shovel is 5,592.8 N when the tillage depth is 25 cm and 7,129 N when the tillage depth is 30 cm. When the tillage speed is 0.2 m/s, the resistance to the deep pine shovel of the drag reduction method in this paper is 521 N. When the tillage speed increases to 1.0 m/s, the resistance of the deep pine shovel in this paper is only 1,035 N. The method in this paper has good drag reduction effect and high application value.

Authors: Lu Chunting , Yang Zheng , Zheng Lei , Liu Zonghui 
Published: October 2022

Abstract
To improve the stability of the lightweight steel structure of super high-rise buildings, the wind-resistance reliability of the structure is analyzed in this paper. Based on the stress model of the lightweight steel structure of super high-rise buildings, the additional internal forces of the lightweight steel structure under strong wind are calculated, and the stress analysis is completed. Then, the data of the lightweight steel structure node of super high-rise buildings are divided into topographic data and ground object data, and part of the data noise is eliminated by filtering calculation, so as to complete the processing of the measurement data of lightweight steel structure by laser scanning. On this basis, combined with the data obtained, the wind-induced internal pressure and surface net wind pressure of the lightweight steel structure of super high-rise buildings are calculated after the wind-induced failure criterion is defined, and the wind-induced internal pressure and surface net wind pressure of the lightweight steel structure are calculated. Additionally, the wind-resistance reliability analysis is completed by combining the stiffness equation. The experimental results show that the method has high reliability and a short analysis time, which fully proves the effectiveness of the method.
The role of steroidogenic factor 1 (SF-1) in steroidogenic cell function of the testes and ovaries of mature mice
Authors: Smith Olivia E , Morin Fanny , Roussel Vickie , Bertucci Micka C , Boyer Alexandre , Murphy Bruce D 
Published: October 2022

In brief
The nuclear receptor steroidogenic factor 1 (SF-1) is essential for mature mouse gonad steroidogenic gene expression, for Leydig and Sertoli cell function, and depletion of SF-1 in steroidogenic cells of the testis compromises steroidogenesis, spermatogenesis and male fertility.

Abstract
Steroidogenic factor 1 (SF-1 or NR5A1) plays an essential role in the development of fetal gonads and regulates genes involved in steroid biosynthesis. Since SF-1 is expressed in multiple cell types in mouse gonads, we developed three novel conditional knockout (cKO) mouse models employing Cre-recombinase and floxed alleles of SF-1 (Nr5a1f/f) to identify its role in testes and ovaries of mature mice: Cytochrome P450 17α-hydroxylase (Cyp17Cre/+;Nr5a1f/f, Leydig and theca cell-specific), aromatase (Cyp19Cre/+;Nr5a1f/f, Sertoli and granulosa cell-specific), as well as a combination of both (Cyp17+Cyp19-Cre;Nr5a1f/f). Compared to control animals, Cyp19-Cre;Nr5a1f/f cKO males showed normal fertility and testicular function. The Cyp17Cre/+;Nr5a1f/f cKO males had smaller testis, with drastically reduced Leydig cell volumes and impaired steroidogenesis, though their reproductive performance remained comparable to controls. Some 50% of Cyp17Cre/++Cyp19Cre/+;Nr5a1f/f double-cKO (dKO) males were infertile, while the remaining 50% showed significantly reduced fertility. These dKO males also had smaller testis with degenerative seminiferous tubules, abnormal Leydig cell morphology and lower levels of intra-testicular testosterone. Abnormal Sertoli cell localization was noted in dKO testes, with increased Sox9, p27 and inhibin subunit ßb and decreased androgen receptor expression. Female mice from all genotypes showed normal reproductive capacity, though steroidogenic gene expression levels were significantly decreased in both Cyp17Cre/+;Nr5a1f/f cKO and dKO females. These results show the essential role of SF-1 in mature mouse gonad steroidogenic gene expression, for Leydig and Sertoli cell function, and that depletion SF-1 in all steroidogenic cells of the testis compromises steroidogenesis, spermatogenesis and male fertility.
David frente a Goliat: el superior interés del menor y el derecho a la tutela judicial efectiva en tela de juicio
Authors: Mayordomo Rodrigo Virginia Victoria 
Published: October 2022

El asesinato de una niña a manos de su padre, al haberle sido retirada contra la voluntad de su madre la vigilancia en las visitas, lleva a cuestionar si prima realmente el superior interés del menor. Doce años de batalla judicial por parte de aquélla dieron como resultado que el Comité de Naciones Unidas para la Eliminación de la Discriminación contra la Mujer condenara al Estado español por negligencia en la protección de la menor. España se negó a admitir la resolución negándole valor ejecutivo y, en consecuencia, a indemnizar a la madre por anómalo funcionamiento de la Administración de Justicia.

BACKGROUND AND OBJECTIVES
Acute illness with malnutrition is a common indication for hospitalization among children in low- and middle-income countries. We investigated the association between wasting recovery trajectories and neurodevelopmental outcomes in young children 6 months after hospitalization for an acute illness.

METHODS
Children aged 2 to 23 months were enrolled in a prospective observational cohort of the Childhood Acute Illness & Nutrition Network, in Uganda, Malawi, and Pakistan between January 2017 and January 2019. We grouped children on the basis of their wasting recovery trajectories using change in mid–upper arm circumference for age z-score. Neurodevelopment was assessed with the Malawi Developmental Assessment Tool (MDAT development-for-age z-score [DAZ]) at hospital discharge and after 6 months.

RESULTS
We included 645 children at hospital discharge (mean age 12.3 months ± 5.5; 55% male); 262 (41%) with severe wasting, 134 (21%) with moderate wasting, and 249 (39%) without wasting. Four recovery trajectories were identified: high–stable, n = 112; wasted–improved, n = 404; severely wasted–greatly improved, n = 48; and severely wasted–not improved, n = 28. The children in the severely wasted–greatly improved group demonstrated a steep positive MDAT-DAZ recovery slope. This effect was most evident in children with both wasting and stunting (interaction wasted–improved × time × stunting: P &lt; .001). After 6 months, the MDAT DAZ in children with wasting recovery did not differ from community children. In children who never recovered from wasting, there remained a significant delay in MDAT DAZ scores.

CONCLUSIONS
Neurodevelopment recovery occurred in parallel with wasting recovery in children convalescing from acute illness and was influenced by stunting.
Effect of scanning strategy on microstructure and mechanical properties of a biocompatible Ti–35Nb–7Zr–5Ta alloy processed by laser-powder bed fusion

AbstractThe influence of scanning strategy (SS) on microstructure and mechanical properties of a Ti–35Nb–7Zr–5Ta alloy processed by laser-powder bed fusion (L-PBF) is investigated for the first time. Three SSs are considered: unidirectional-Y; bi-directional with 79° rotation (R79); and chessboard (CHB). The SSs affect the type and distribution of pores. The highest relative densities and more homogeneous distribution of pores are obtained with R79 and CHB scanning strategies, whereas aligned pores are formed in the unidirectional-Y. The SSs show direct influence on the crystallographic texture with unidirectional-Y strategy showing fiber texture. The R79 strategy results in a weak texture and the CHB scanning strategy forms a randomly oriented heterogeneous grain structure. The lowest Young modulus is obtained with the unidirectional-Y strategy, whereas the R79 strategy results in the highest yield strength. It is shown that the SSs may be used for tuning the microstructure of a beta-Ti alloy in L-PBF.
