Cathodic protection of precast, prestressed multistory car park slabs, using a surface applied galvanic zinc layer anode
Authors: Giorgini Roberto , Souchal Frédéric , Grill Michel , Michaux Christophe , Thyes Leon 
Published: June 2022

A surface applied galvanic Zinc Layer Anode (ZLA) system was installed on a multistory carpark structure to provide cathodic protection to the soffits of the prestressed hollow concrete slabs, which were suffering from chloride induced corrosion deterioration. This paper evaluates the cathodic protection system performance against the international standard for Cathodic Protection of Steel in Concrete, ISO 12696 [13], 17 months after commissioning.
A surface applied galvanic Zinc Layer Anode was selected to provide cathodic protection, as this offered a low risk of exceeding the hydrogen embrittlement potential and provided a unique application approach, which was compatible with the hollow slab construction.
During the pilot phase, a total of 40 m2 of ZLA was applied into two anode zones and monitored for a month, to prove concept and system performance. Following the pilot phase the remainder of the cathodic protection works were completed, extending to a total concrete area of 320 m2. The installed system was provided with embedded reference electrodes and wired to enable full performance evaluation as per the requirements of ISO 12696. Three battery powered web-based monitoring devices were used for remote system monitoring and performance assessment.
The initial performance data following 17 months of operation, identified that all 12 reference electrodes installed across the 6 anode zones all met the 100mV depolarization criteria within a 24-hour period, as per the requirements of clause 8.6b of ISO 12696. The anode to cathode current was also recorded continuously over this operational period and used to evaluate environmental effects and predicted actual anode service life.

AbstractCyclophosphamide (CYP) is a potent DNA-interactive anticancer drug; however, its
clinical drawbacks are chiefly associated with induction of oxidative
multi-organ toxicity. Sitagliptin (STG) is an antidiabetic dipeptidyl
peptidase-4 inhibitor drug with antioxidant efficacy. Herein, we have explored
whether STG could abrogate the CYP-induced oxidative stress-mediated cardiac and
hepatorenal toxicities in male rats. Sitagliptin (20 mg/kg, o.p)
was administered to rats for 5 consecutive days against organ toxicities induced
by CYP (200 mg/kg, i.p) on day 5 only. CYP induced marked
injuries in the liver, kidney and heart underscored by prominent increases in
serum activities of ALT, AST, LDH, creatine kinase and levels of urea, uric acid
and creatinine, while albumin level significantly decreased compared to normal
control rats. Further, CYP considerably reduced the activities of SOD, CAT, GPx,
and levels of GSH, whereas MDA level increased significantly in comparison to
control rats. These biochemical alterations were confirmed by multiple
histopathological lesions in the tissues. Interestingly, the STG pretreatment
abrogated the biochemical and histopathological changes induced by CYP. These
results provide first evidence that repurposing STG may protect the liver,
kidney and heart from the oxidative deterioration associated with CYP
chemotherapy.

Authors: Gejoe G. , Yadev I.P. , Kumaran Amrutha , Swasthik K.S. , Chisthi Meer M. 
Published: June 2022

Abstract
Background Hashimoto's thyroiditis (HT) is the commonest autoimmune thyroid pathology. It has been reported in increased numbers recently, probably due to the increase in autoimmune diseases across many parts of the world. It is sometimes found associated with other diseases as well as other diseases of the thyroid. There is an unproven association of this condition with thyroid cancer, particularly papillary thyroid carcinoma (PTC).
Methods This was a retrospective study performed over a period of 5 years. The objectives of this study were to find out the prevalence of histopathologically proven HT in surgically resected thyroid glands for various indications and its association with other thyroid disorders, especially thyroid malignancies. Total 4,630 patients who underwent thyroidectomy during the study period and met the criteria for inclusion were considered for analysis.
Results Histopathologically proven features of HT were present in 1,295 (28%) of the cases. Among these, 445 (34.36%) had only HT while 850 (65.66%) had HT along with other thyroid diseases. The most common disease associated with HT was multinodular goiter (44.2%), followed by PTC (15.2%). Patients with HT exhibited a higher rate of papillary cancer (16.7%) compared with patients without this pathology (13.8%). Statistically significant association between papillary cancer and HT was found among the female patients.
Conclusion The prevalence of HT in patients undergoing thyroidectomy is high in the studied population. A statistically significant association exists between papillary thyroid cancer and thyroiditis among female patients. This could form the basis for further research along these lines.

Abstract
Presence of the artery of Desproges-Gotteron is extremely rare. It has seldom been mentioned in the literature as well. The authors have dealt with a case of a dural arteriovenous malformation (AVM) of conus medullaris fed by the artery of Desproges-Gotteron in a young female of 19 years. The patient presented with a tingling sensation of lower limbs, progressive difficulty walking, and incontinence of the bladder. There was weakness in all groups of muscle of both lower limbs and definite sensory level on examination. Magnetic resonance imaging revealed multiple flow voids at the level of conus medullaris. Spinal digital subtraction angiography (DSA) revealed dural AVM at the level of conus. The patient underwent transarterial embolization with 30% Endocryl(n-butyl cyanoacrylate) in two stages, and repeated spinal DSA revealed no evidence of residual AVM. Patient's neurology gradually improved. Almost 2 years down the line, the follow-up revealed gradual but complete motor and sensory deficits recovery except for occasional burning pain in lower limbs. Spinal AVM supplied by the artery of Desproges-Gotteron is a unique variation. Moreover, the authors believe that it is the first reported case in Bangladesh.
Umbilical Nodule Metastasis from Unknown Primary: Diagnostic and Therapeutic Dilemma
Authors: Gupta Sweety , Sharma Gaurav , Sharma Nidhi , Mandal Shreyosi , Gupta Amit , Gupta Manoj 
Published: June 2022

AbstractUmbilical nodule metastasis is not a common presentation of carcinoma of unknown primary. It may be the presenting symptom of a primary malignancy or as metastatic site of previously diagnosed cancer and is considered to be a poor prognostic finding. We here report a case of young male who presented with umbilical mass, but the primary could not be localized even after thorough investigations and work up. Also, there existed therapeutic dilemma because immunohistochemistry did not favor one site, and so he was considered for combination chemotherapy in view of unresectable disease.

Published: June 2022

Abstract
Background Mediastinal cysts are benign lesions that may be seen in adulthood as well as in childhood. Mostly congenital lesions constitute 20 to 32% of lesions located in the mediastinum. The main cystic masses are congenital benign cysts (bronchogenic, esophageal replications, neuroenteric, pericardial and thymic cysts), meningocele, mature cystic teratoma, and lymphangioma. In this study, we aimed to analyze the mediastinal cysts operated in our clinic according to the histopathological type, surgical type, morbidity rates and to contribute to the literature on these rare lesions.
Methods The records of patients with mediastinal cysts who were operated in Gazi University Faculty of Medicine Department of Thoracic Surgery, between January 2013 and June 2021, were reviewed retrospectively.
Results A total of 32 patients were included the study. Thirteen (40.6%) of the patients were male and 19 (59.4%) were female. The mean age was 45 (range: 12–71). The most common symptom in patients was chest pain with 12 patients. Histopathologically, the most common subtype was thymic cyst. Video-assisted thoracic surgery was applied in 19 patients (59.3%), thoracotomy in 8 patients (25%), and sternotomy in 5 patients (15.63%). There was no mortality.
Conclusion In patients with mediastinal cysts, the prognosis after complete excision is excellent and rates of morbidity and mortality associated with surgery are low.
‘Arm’s length’ phraseology?
Authors: Rojas Díaz José Luis 
Published: June 2022

AbstractIn the last decades, the study of phraseology within general and specialized lexicographic resources has been of interest to scholars. However, phraseology has not been studied in language for specific purposes (LSP) as much as in language for general purposes (LGP). Therefore, this study (i) offers an overview of the definitions regarding LSP phraseology, (ii) provides a series of linguistic analyses of specialized phraseological units (SPUs) extracted from a specialized bilingual dictionary, and (iii) draws a comparative line between LGP and LSP phraseology. To do so, 11,086 entries were extracted to build the analysis database. This study provides 1,054 morphosyntactic and 4,369 semantic patterns, a definition and a taxonomy of SPUs based on the data analysis and revision of LGP phraseology notions, and a hybrid lexicographic indexation method for SPUs. The contributions of this paper answer the question ‘what is a SPU?’; while highlighting similarities and differences with LGP phraseology.
Yukawa black holes from interacting vacuum
Authors: Maier Rodrigo 
Published: June 2022

Abstract
In this paper we obtain an exact solution of Einstein field equations assuming an interaction between a vacuum component and the Maxwell field. The key feature of such interaction refers to a simple stress exchange so that the electromagnetic field naturally incorporates the Yukawa potential. It is shown that the resulting spacetime thus obtained can either be a naked singularity or a black hole with an inner Cauchy horizon R
− and an exterior event horizon R
+. For this latter configuration we examine the group velocity of test photons in the region R > R
+. Beyond a lower bound for the frequency we show that superluminal velocities arise in a neighbourhood of the event horizon and that the coupling parameter of the interaction is actually connected to a nonvanishing rest mass for the photon.
Benchmark of few-level quantum theory vs ab initio numerical solutions for the strong-field Autler–Townes effect in photoionization of hydrogen
Authors: Younis D , Eberly J H 
Published: June 2022

Abstract
The temporal and spectral consequences of an intermediate resonance en route to photoionization are investigated theoretically in two ways: by solving few-level model equations and by ab initio numerical solution of the time-dependent Schrödinger equation, in both cases for hydrogen in three dimensions. The model consists of atomic states resonantly field-dressed in a three-level reduction of the hydrogen atom that consists of the 2p–3d (Balmer) transition and one energetically-distant continuum state. The model’s level occupation probabilities are derived from three Schrödinger amplitude equations and are benchmarked against an ab initio numerical solution for the hydrogen electron’s wavefunction under the same field. We examine contrasts between the results of the two approaches with a particular focus on Autler–Townes doublets that appear in the photoelectron spectrum.
Atomistic origin of nano-silver paracrystalline structure: molecular dynamics and x-ray diffraction studies
Authors: Jurkiewicz Karolina , Kamiński Michał , Bródka Aleksander , Burian Andrzej 
Published: June 2022

Abstract
Classical molecular dynamics (MD) and x-ray diffraction (XRD) have been used to establish the origin of the paracrystalline structure of silver nanoparticles at the atomic scale. Models based on the face-centred cubic structure have been computer generated and their atomic arrangements have been optimized by the MD with the embedded-atom model (EAM) potential and its modified version (MEAM). The simulation results are compared with the experimental XRD data in reciprocal and real spaces, i.e. the structure factor and the pair distribution function. The applied approach returns the structural models, defined by the Cartesian coordinates of the constituent atoms. It has been found that most of the structural features of Ag nanoparticles are better reproduced by the MEAM. The presence of vacancy defects in the structure of the Ag nanoparticles has been considered and the average concentration of vacancies is estimated to be 3 at.%. The average nearest-neighbour Ag–Ag distances and the coordination numbers are determined and compared with the values predicted for the bulk Ag, demonstrating a different degree of structural disorder on the surface and in the core, compared to the bulk crystalline counterpart. It has been shown that the paracrystalline structure of the Ag nanoparticles has origin in the surface disorder and the disorder generated by the presence of the vacancy defects. Both sources lead to network distortion that propagates proportionally to the square root of the interatomic distances.
Feed-forward neural network based variational wave function for the fermionic Hubbard model in one dimension
Authors: Sarder Md Tahir Hossain , Medhi Amal 
Published: June 2022

Abstract
We explore the suitability of a feed-forward neural network (FNN) to represent the ground state of the fermionic Hubbard model in one dimension (1D). We consider the model at half-filling, represent the ground state wave function in terms of an FNN and optimize it using the variational Monte Carlo (VMC) method. The results are compared with the exact Bethe Ansatz solution. We find that for lattice sizes which give a ‘filled-shell’ condition for the non-interacting Fermi sea wave function, a simple FNN performs very well at all values of Hubbard interaction U. For lattice sizes where this condition is not obtained, the simple FNN fails and we find a modified network with a ‘sign’ component (sFNN) to work in such cases. On the flip side, though we find the FNN to be successful in providing an unbiased variational wave function for the fermionic many-body system in 1D, the computational cost for the wave function scales up rapidly with lattice size which limits its applicability.
A hybrid shape memory polymer filled metallic foam composite: shape restoring, strain sensing, Joule heating, strengthening, and toughening
Authors: Abedin Rubaiyet , Konlan John , Feng Xiaming , Mensah Patrick , Li Guoqiang 
Published: June 2022

Abstract
In this paper, an open-cell metallic foam was filled in by a tough shape memory polymer (SMP), to form a hybrid metal/polymer composite with multifunctionalities and enhanced mechanical properties. This work aims to study the positive composite actions between the metallic skeleton and the SMP filler. Mechanical, thermal, and conductive properties of the resulting hybrid composite were evaluated and compared to the individual components. Uniaxial compression tests and shape memory effect tests were conducted. Results demonstrated an improvement in the compressive strength and toughness. The hybrid composite also exhibited excellent shape recovery and high recovery stress of 1.76 MPa. Infrared thermography has been used to verify the free shape recovery by Joule heating. Sandwich structures with the hybrid composite as the core were studied through low velocity impact test and three-point bending test. The sandwich structures with the composite foam core showed significant performance improvement in both tests. Electrical resistivity study during the three-point bending test validates the possible application of this multifunctional polymer-aluminum open cell foam composite as strain sensor. This type of hybrid composites can be beneficial in many industrial sectors that search for an ideal combination of high strength, high toughness, low weight, damage sensing, and excellent energy absorption capabilities.
Electron–phonon coupling constant and BCS ratios in LaH10−y
doped with magnetic rare-earth element
Authors: Talantsev Evgeny F 
Published: June 2022

Abstract
Stoichiometric near-room-temperature superconductors (NRTS) (for instance, H3S and LaH10) exhibit a high ground-state upper critical field, B
c2(0) ⩾ 100 T, so that the magnetic phase diagram in these materials cannot be measured in non-destructive experiments. However, (Semenok et al 2022 Adv. Mater.) proposed the idea of exploring the full magnetic phase diagram in NRTS samples, in which the superconducting order parameter is suppressed by magnetic element doping. If the elements areuniformly distributed in the material, then the theory of electron–phonon mediated superconductivity predicts the suppression of the order parameter in a 3D s-wave superconductor. (Semenok et al 2022 Adv. Mater.) experimentally proved this idea by substituting lanthanum with the magnetic rare-earth neodymium in (La1−x

Photocatalytic degradation of anionic dye using well-crystalline SnWO4 polyoxometalate
Authors: Alharthi Fahad A , AlFawaz Amal , Ahmad Naushad 
Published: June 2022

Abstract
Rose Bengal (RB) is well known anionic dye and considered as one of the major water pollutants. It can be hazardous to human and aquatic life. Polyoxometalates play major role for the decomposition of such type of pollutants. In this study, cubic tin tungsten oxide nanoparticles (β-SnWO4-NPs), a polyoxometalate, had been synthesized by sol-gel method and physically characterized by XRD, FT-IR, Raman, UV-DRS, PL, XPS, and SEM. Photocatalytic performance was evaluated by photodegradation of RB under visible light irradiation, and corresponding photodegradation mechanism was also proposed. The role of various reaction parameters such as catalyst amount, dye concentration and solution pH were investigated. Under given parameters the degradation percentage of RB was found to ∼94.6% after 150 min. The cubic crystal structure and honeycomb morphology of the β-SnWO4-NPs endows excellent photocatalytic properties. The radical scavenger investigations showed that photogenerated h+, O2
•−, and •OH radicals were responsible for RB degradation. The obtained results can be effectively used in future for the wastewater treatment.
Probing cosmic strings by reconstructing polarization rotation of the cosmic microwave background
Authors: Yin Weichen Winston , Dai Liang , Ferraro Simone 
Published: June 2022

Abstract
Cosmic birefringence — the rotation of the polarization of the cosmic microwave background (CMB) photons as they travel to the Earth — is a smoking gun for axion-like particles (ALPs) that interact with the photon. It has recently been suggested that topological defects in the ALP field called cosmic strings can cause polarization rotation in quantized amounts that are proportional to the electromagnetic chiral anomaly coefficient 𝒜, which holds direct information about physics at very high energies. In this work, we study the detectability of a random network of cosmic strings through estimating rotation using quadratic estimators (QEs). We show that the QE derived from the maximum likelihood estimator is equivalent to the recently proposed global-minimum-variance QE; the classic Hu-Okamoto QE equals the global-minimum-variance QE under special conditions, but is otherwise still nearly globally optimal. We calculate the sensitivity of QEs to cosmic birefringence from string networks, for the Planck satellite mission, as well as for third- and fourth-generation ground-based CMB experiments. Using published binned rotation power spectrum derived from the Planck 2015 polarization data, we obtain a constraint 𝒜2 ξ0 < 0.93 at the 95% confidence level, where ξ0 is the total length of strings in units of the Hubble scale per Hubble volume, for a phenomenological but reasonable string network model describing a continuous distribution of string sizes. Looking forward, experiments such as the Simons Observatory and CMB-S4 will either discover or falsify the existence of an ALP string network for the theoretically plausible parameter space 𝒜 ξ0 ≳ 0.01.
Discovery of new characterizations of parameter distributions in a semi- empirical mass model: an investigation by dividing an overdetermined system into numerous balanced subsystems*
Authors: Meng Hai-Yan , Wang Hua-Lei , Zhang Zhen-Zhen , Liu Min-Liang 
Published: June 2022

Abstract
We propose and test a new method of estimating the model parameters of the phenomenological Bethe-Weizsäcker mass formula. Based on the Monte Carlo sampling of a large dataset, we obtain, for the first time, a Cauchy-type parameter distribution formed by the exact solutions of linear equation systems. Using the maximum likelihood estimation, the location and scale parameters are evaluated. The estimated results are compared with those obtained by solving overdetermined systems, e.g., the solutions of the traditional least-squares method. Parameter correlations and uncertainty propagation are briefly discussed. As expected, it is also found that improvements in theoretical modeling (e.g., considering microscopic corrections) decrease the parameter and propagation uncertainties.
