Published: October 2024

AbstractDuring the process of external work, the energy of the negative oxygen balanced 5,5′‐Bi‐tetrazolium‐1,1′dioxyhydroxylammonium salt (TKX‐50) is not fully released, resulting in low energy utilization efficiency and the generation of harmful gases that pollute the environment. Based on this, in order to adjust the oxygen balance of TKX‐50, nano TKX‐50/AP composites with positive, zero and negative oxygen balance were prepared by emulsion method. The morphology of nano TKX‐50/AP composite was similar to that of hedgehog‐like spherical‐like particles, with many dense pores formed on the surface, and the average particle size was about 30 μm. During the composite process, part of TKX‐50 reacted with AP to form 5,5′‐bistetrazole‐1,1′dioxidamide (ABTOX). The first thermal decomposition peak temperature of zero‐oxygen balance TKX‐50/AP composite was 236.0°C, which was slightly reduced compared with that of TKX‐50. The second thermal decomposition peak temperature was 275.1°C, which was 22.2°C higher than that of TKX‐50. The heat release of zero‐oxygen balance TKX‐50/AP composite reached 2206 J g−1, which increased by 35.9% compared to TKX‐50, and the energy utilization efficiency was also greatly improved. The drop height of 50% explosion probability (H50) of zero‐oxygen balance TKX‐50/AP composite was 63.5 cm, and the explosion probability of friction sensitivity was 72%. Compared with TKX‐50, it increased by 15.1 cm and decreased by 28%, respectively. The results showed that the mechanical safety performance of TKX‐50 had been improved.

Published: October 2024

AbstractThroughout the entire operational lifespan of a solid rocket motor, the propellant grain experiences creep due to gravitational forces, potentially influencing the motor′s reliability. To enhance the efficiency of creep tests for solid propellants, short‐term (3000 seconds) creep tests were conducted on nitrate ester plasticized polyether (NEPE) propellant at stress levels of 0.15 MPa, 0.20 MPa, 0.25 MPa, and 0.30 MPa using both the step stress method (SSM) and the conventional constant creep test (CCT). Furthermore, mid‐term (10000 seconds) and long‐term (7 days) creep tests were conducted. Based on the traditional generalized Kelvin model, the Saint‐Venant body was incorporated to derive a visco‐elastic‐plastic model with overstress considered, and constitutive model parameters were determined through data fitting. The findings demonstrate the efficacy of the constitutive model in well characterizing propellant creep behavior. According to the model, the yield stress of NEPE propellant was determined to be 0.2302 MPa, representing a significant 64.03% reduction compared to its design strength. This insight holds relevance for structural integrity analysis and the evaluation of solid motor storage life.

AbstractBackgroundTo evaluate how prostate‐specific antigen (PSA) levels decrease after removal of isolated prostate cancer (PCa) nodal metastases in relation to their diameter/volume (“PSA‐density of PCa‐metastases”) and maximum standardized uptake value (SUVmax).MethodsA total of 83 consecutive patients with solitary nodal recurrence after radical prostatectomy who underwent prostate‐specific membrane antigen‐radioguided salvage surgery were retrospectively analyzed. Using multivariable linear regression models, the PSA‐decrease after removal of each PCa‐metastases (=PSA‐contribution of each PCa‐metastases) was correlated with the long axis diameter/estimated volume and the SUVmax of each removed metastasis. Sizes were measured by imaging and histopathologic examination.ResultsA total of 83 patients were included with a median (interquartile range [IQR]) PSA‐decrease of 0.56 [0.22, 1.31] ng/mL after salvage surgery. The median [IQR] long axis diameters in imaging and histopathological examination were 8.0 [6.0, 11.0] mm and 8.4 [5.5, 11.1] mm, respectively. The median [IQR] estimated volumes were 0.13 [0.05, 0.32] cc (imaging) and 0.05 [0.02, 0.17] cc (pathology). In multivariable linear regression analyses, the estimated PSA‐contribution ([95% confidence interval [CI]) of each millimeter of long axis diameter was 0.09 [0.03, 0.14] ng/mL (imaging) or 0.08 [0.03, 0.12] ng/mL (histology). The minimum diameter for biochemical recurrence (PSA ≥ 0.2 ng/mL) was >2.2 mm (imaging) or >2.5 mm (histology). The estimated PSA‐contribution [95% CI] of each cc cancer volume was 1.23 [0.51, 1.94] ng/mL (imaging) or 1.46 [0.40, 2.52] ng/mL (histology). SUVmax as surrogate parameter for tissue composition was associated with increased PSA‐contribution of PCa‐metastases (+0.03–0.05 ng/mL per unit increase).ConclusionsThe diameter/volume and SUVmax of metastatic tissue correlate with its contribution to PSA levels. Therefore, very small metastases may produce too little PSA for biochemical recurrence.
Disturbance observer based adaptive predefined‐time sliding mode control for robot manipulators with uncertainties and disturbances
Authors: Sun Guofa , Liu Qingxi , Pan Fengyang , Zheng Jiaxin 
Published: October 2024

AbstractThis article develops a predefined‐time sliding mode control approach for systems with external disturbances and uncertainties through a nonlinear disturbance observer (DO). For addressing predefined‐time stabilization problem of robotic manipulator system, a predefined‐time sliding mode surface is proposed, ensuring system states converge to origin within a predefined‐time once sliding mode surface is attained. Compared to conventional fixed‐time and finite‐time control strategies, a distinctive advantage of this scheme is that system settling time can be explicitly chosen in advance and independent of system states. To achieve predefined‐time performance, a disturbance observer is introduced to generate the disturbance estimate, which can be incorporated into controller to counteract disturbance. To address the systems uncertainty, an adaptive law is employed to estimate the unknown upper boundary of system uncertainties. Finally, the effectiveness and performance of the proposed scheme are illustrated by simulation and experiment.
‘Where else can they go?’: Violence, resistance and the socio‐cultural trajectories of Kashmiri women in Freny Manecksha's Behold I Shine: Narratives of Kashmir's Women and Children
Authors: Pal Payel , Karmakar Goutam 
Published: October 2024

AbstractIn the armed conflict between Kashmiri militancy and the Indian state forces, Kashmiri women have been relentless victims of abduction, rape, molestation, and cruel objectification by the militaristic patriarchs of both sides. In the context of the state's unaccountability, the rebuttal of justice is horrific in Kashmir. Consequently, due to predominant masculine, state‐centric, absolutist, and neo‐realist perceptions, the majority of atrocities against Kashmiri women have gone unregistered and unreported, failing to reach the pan‐Indian masses through the dominant media and literary narratives. This article explicates Freny Manecksha's book Behold I Shine: Narratives of Kashmir's Women and Children (2017) as a unique retelling of Kashmiri women's physical violence, fears, trauma, and, most importantly, their fortitude and recuperation. Drawing on feminist views on rape and repression, it exposes how rape in Kashmir incessantly functions as a weapon of suppression, relegating women to the most precarious position. Simultaneously, the discussion demonstrates how rape and oppression render Kashmiri women docile and vulnerable to cultural and collective trauma by employing the Foucauldian notion of docility. The article further addresses how Kashmiri women repudiate the traditional divides of private and public, overturn the social expectations of womanhood, contest the patriarchal excesses of militaristic Kashmir vis‐à‐vis their resilience, and protest against state‐sponsored violence. Thus, the article posits Manecksha's writing as a counter‐historiographic narrative for the marginalized voices of Kashmiri women, whose ways of redressing their grievances constitute subversive modes of resistance.

Published: October 2024

AbstractNowadays, retrofitting and rehabilitation of deteriorated reinforced concrete structures are becoming a growing need of the construction industry instead of demolishing aged structures. The application of fabric‐reinforced cementitious matrix (FRCM) on the existing concrete structures is one of the sustainable solutions to retrofit the concrete structures. This study used machine learning (ML) models such as linear regression (LR), support vector machines (SVM), and adaptive neuro‐fuzzy inference systems (ANFIS) to estimate the compressive strength (CS) of columns wrapped with FRCM. The experimental dataset of 301 column specimens was collected including input parameters such as cross‐sectional properties, mechanical properties of concrete and steel, and characteristics of FRCM material. Apart from ML models, seven analytical models were also used to compare the accuracy and precision of ML models. The results illustrate that the ANFIS model outperformed other ML models and established itself as a dependable and precise model. The R‐value of the ANFIS model was 0.9816, whereas R‐values of 0.9269 and 0.9572 were achieved by LR and SVM models, respectively. In addition, the MAPE value acquired by the ANFIS model was 1.52% which was lower than those of the LR model by 73.24%, and the SVM model by 60.60%, respectively. As the precision of the ANFIS model was higher as compared with SVM and LR models, so, the developed ANFIS‐based mathematical model can be easily used to predict the CS of FRCM‐strengthened concrete columns. The developed model is accurate, economical, and fast; and can be utilized by FRCM applicators and structural designers.

Published: October 2024

AbstractAs aging infrastructures raise public concerns, evaluating their performance is crucial for maintaining structural integrity, especially for corroding prestressed concrete members. These structures may experience substantial tendon cross‐sectional area loss before any visible deterioration becomes detectable. While various non‐destructive techniques (NDT) have proven effective in labs, correlating corrosion‐induced damage in field members remains a challenge. Establishing these correlations is key for understanding the overall performance of aging structural concrete elements and ensuring their continued safe operation through non‐invasive means. This paper investigates various NDTs on a concrete bridge deck, aiming to correlate results. Visual inspection, Schmidt rebound hammer, Ultrasonic Pulse Velocity (UPV), corrosion detection techniques, Ground Penetrating Radar (GPR), Ultrasonic Pulse Echo (UPE), and Impact Echo (IE) methods are evaluated for detecting concrete deck damage. Results show the methods' capabilities in detecting defects to a certain extent, highlighting their potential in assessing aging concrete infrastructures.
Analysis of wind vibration characteristics of a slab‐type high‐rise residential building

Published: October 2024

AbstractA slab‐type high‐rise residential building with a depth‐to‐width ratio exceeding 6 was studied. Multi‐point surface pressure measurements and high‐frequency force balance (HFFB) wind tunnel tests were conducted to investigate the wind‐induced dynamic characteristics of the building. The dynamic responses, especially accelerations closely related to serviceability performance, were determined and examined in both time and frequency domains. The spectral properties of the time‐history acceleration responses were compared with frequency‐domain results. Analyses showed acceleration responses were amplified when along‐wind or across‐wind directions aligned with the shorter building axis. The slab‐type cross‐section reduced vortex shedding in the across‐wind direction. As a result, peak accelerations were often dominated by along‐wind excitations. Torsional accelerations approached those induced by along‐wind winds, likely due to both fundamental and higher modes.
Exploring Preservice Teachers' Translanguaging Practices and Perceptions in Teacher Training: A Global Englishes Perspective
Authors: Li Hongqin , Pan Lin , Seargeant Philip , Block David 
Published: October 2024

AbstractThis study explores how preservice English teachers in China perceive and leverage their Chinese and English linguistic repertoires in ELT methodology training, and how a reflective understanding of their use of these repertoires can contribute to their development as teachers. To understand how their practices and conceptualizations of language and teaching are in accord with an orientation toward or away from principles of Global Englishes Language Teaching (GELT), we drew on theories of translanguaging space and stance (García, Ibarra Johnson, & Seltzer, 2017; Li, 2011) and the GELT framework (Rose & Galloway, 2019) to examine preservice teachers' experiences in teacher training. Through multimodal conversational analysis of lesson recordings, we found that preservice teachers created translanguaging spaces to utilize different languages in the critical negotiation of pedagogies. In addition, they displayed traslanguaging stance by strategically incorporating multimodal and multicultural resources in microteachings. We also carried out semistructured interviews in which the preservice teachers, influenced by factors such as language ideologies and curriculum design, displayed mixed views toward translanguaging practices in teacher training, and the ELT classroom. By investigating the feasibility of GELT in TESOL teacher training in China, this study emphasizes the need to empower preservice teachers as critical agents in terms of assessment design and curriculum delivery for sustainable Global Englishes‐oriented innovations to occur.
Brane-like solutions and other non-supersymmetric vacua
Authors: Mourad J. , Raucci S. , Sagnotti A. 
Published: October 2024

Abstract
After recasting the standard charged and uncharged brane profiles in the harmonic gauge, we explore solutions with the same isometries where the potentials V = T eγ ϕ of ten-dimensional non-supersymmetric strings are taken into account. Combining a detailed catalog of the possible asymptotics with some numerical results suggests that these spherically symmetric backgrounds terminate at singularities within finite proper distances.
Low and moderate x gluon contribution to exclusive Compton scattering processes
Authors: Boussarie R. , Mehtar-Tani Y. 
Published: October 2024

Abstract
We revisit the high energy semi-classical description of the exclusive processes DVCS, TCS, and Double DVCS by explicitly keeping track of the Feynman x dependence in both the hard and the hadronic matrix elements. This is achieved by a modification of the standard shock wave approximation to derive the effective Feynman rules, which leads to a generic expression on which we then perform a partial twist expansion to get rid of quantities suppressed by the proper physical scales. We obtain a compact factorized master formula that can be used to investigate the Bjorken limit at leading twist. In particular, we recover the full one-loop result in the collinear limit for pure gluon exchange with the target. Finally, we discuss the subtleties in taking the simultaneous collinear and small x limit.

Published: October 2024

Abstract
We study the stabilization of a twisted modulus in Type IIB flux compactifications on a mirror of the rigid Calabi-Yau threefold. By analyzing the effective action of twisted and untwisted moduli, we find that three-form fluxes satisfying the tadpole cancellation conditions lead to supersymmetric AdS vacua. We also investigate swampland conjectures on this non-geometric background.
Classes of holographic Mott gaps

Published: October 2024

Abstract
The fermion gaps are classified into order gap or Mott gap depending on the presence/absence of the order parameter. We construct the holographic model of the Mott gap using the field that is supported by the density only without introducing any order parameter. We then classify the Mott gap, depending on the shape of the gap in the density of states and whether the Fermi surface is touching the valence bond or not, into three classes: i) Symmetric gap, ii) Asymmetric gap with isolated Fermi sea. iii) Asymmetric gap with Fermi sea touching the valence band. Finally, we identify possible non-minimal gauge interactions that produce a flatband without symmetry breaking.
CFT duals of Kerr-Taub-NUT and beyond
Authors: Perry Malcolm J. , Rodriguez Maria J. 
Published: October 2024

Abstract
The duality relating the four-dimensional Kerr-Taub-NUT black hole to a thermal two-dimensional CFT with central charges cL = cR = 12J0 is analyzed in detail, generalizing an argument given recently for Kerr within the soft-hair approach. The hidden conformal symmetry is realized in the form of V irL × V irR diffeomorphisms which act non-trivially on the black hole horizon. Semiclassical formulae are derived for the temperature and central charges of the dual CFT. Assuming the applicability of the Cardy formula, these CFT quantities precisely reproduce the macroscopic Bekenstein-Hawking area law. Various further generalizations including the complete family of black holes in four dimensions are discussed.

AbstractToday, more than 90% of inpatients hospitalized with Major Depression or Schizophrenia are treated with psychotropic drugs. Since none of the treatment options is causal, response rates are modest and the course of recovery is very heterogeneous. Genetic studies on the etiology and pathogenesis of major psychiatric disorders over the past decades have been largely unsuccessful. Likewise, genetic studies to predict response to psychopharmacological treatment have also not been particularly successful. In this project we have recruited 902 inpatients with ICD-10 diagnoses of schizophrenic (“F2 patients”) or depressive disorders (“F3 patients”). The study assessed today’s acute inpatient treatment regimens with up to 8 repeated measurements regarding the time course of recovery and adverse side effects. The genotyping included 100 candidate genes with genotypic patterns computed from 549 Single Nucleotide Polymorphisms (SNPs). To predict response to psychopharmacological treatment, we relied on a multidimensional approach to analyzing genetic diversity in combination with multilayer Neural Nets (NNs). Central to this new method were the “gene vectors” that (1) assessed the multidimensional genotypic patterns observed with genes; and (2) evaluated the correlations between genes. By means of these methods, we searched for combinations of multidimensional genotypic patterns that were characteristic of treatment responders while being rare among non-responders. The chosen method of approach provided a powerful technique to detail the complex structures of SNP data that are not detectable by conventional association methods. Molecular-genetic NNs enabled correct classification of 100% “non-responders”, along with 94.7% correctly classified “responders” among the F2 patients, and 82.6% correctly classified “responders” among the F3 patients. The F2 and F3 classifiers were not disjoint but showed an overlap of 29.6% and 35.7% between the diagnostic groups, thus indicating that clinical diagnoses may not constitute etiologic entities. Our results suggested that patients may have an unspecific physical-genetic disposition that enables, facilitates, impedes or prevents recovery from major psychiatric disorders by setting various thresholds for exogenous triggers that initiate improvement (“recovery disposition”). Even though this disposition is not causally linked to recovery, it can nonetheless be clinically used in the sense of a “surrogate”. Indeed, clinicians are also interested in reliable tools that can “do the job”, despite the fact that etiology and pathogenesis of the treated disorders remain unknown.
Postoperative recovery in peroral versus intravenous antibiotic treatment following laparoscopic appendectomy for complicated appendicitis: a substudy of a cluster randomized cluster crossover non-inferiority study

Published: October 2024

Abstract
Background
Acute appendicitis is the most common cause of abdominal pain requiring surgery, usually managed with laparoscopic appendectomy. In Denmark, the standard postoperative treatment for complicated cases involves intravenous antibiotics. This study compares peroral versus intravenous antibiotics in the context of fast-track surgery and Enhanced Recovery After Surgery (ERAS) protocols. Our objective is to evaluate the impact of peroral versus intravenous antibiotics on patient-reported outcomes following laparoscopic appendectomy for complicated appendicitis.

Methods
This was a sub-study within a broader Danish cluster-randomized non-inferiority trial conducted at Zealand University Hospital, focusing on adult patients undergoing laparoscopic appendectomy for complicated appendicitis. Participants were randomized into two groups: one receiving a three-day course of peroral antibiotics and the other intravenous antibiotics after surgery. Recovery quality was assessed on the third postoperative day using the Quality of Recovery-15 (QoR-15) questionnaire.

Results
The study included 54 patients, 23 in the peroral and 31 in the intravenous groups. The peroral group reported significantly better recovery outcomes, with higher QoR-15 scores (mean difference of 12 points, p < 0.001). They also experienced shorter hospital stays, averaging 47 h less than the intravenous group (p < 0.001). No significant differences between the groups were observed in readmissions or severe postoperative complications.

Conclusions
Peroral antibiotic administration after laparoscopic appendectomy for complicated appendicitis significantly improves patient recovery and reduces hospital stay compared to intravenous antibiotics. These results advocate a potential shift towards peroral antibiotic use in postoperative care, aligning with ERAS principles.
