A time-dependent momentum-resolved scattering approach to core-level spectroscopies
Authors: Feiguin Adrian , Nocera Alberto , Zawadzki Krissia 
Published: October 2022

Abstract
While new light sources allow for unprecedented resolution in experiments with X-rays, a theoretical understanding of the scattering cross-section is lacking. In the particular case of strongly correlated electron systems, numerical techniques are quite limited, since conventional approaches rely on calculating a response functon(Kramers-Heisenberg formula) that is obtained from a perturbative analysis of scattering processes in the frequency domain. This requires a knowledge of a full set of eigenstates in order to account for all intermediate processes away from equilibrium, limiting the applicability to small tractable systems. In this work, we present an alternative paradigm, recasting the problem in the time domain and explicitly solving the time-dependent Schr\"odinger equation without the limitations of perturbation theory: a faithful simulation of the scattering processes taking place in actual experiments, including photons and core electrons. We show how this approach can yield the full time and momentum resolved Resonant Inelastic X-Ray Scattering (RIXS) spectrum of strongly interacting many-body systems. We demonstrate the formalism with an application to Mott insulating Hubbard chains using the time-dependent density matrix renormalization group method, which does not require a priory knowledge of the eigenstates and can solve very large systems with dozens of orbitals. This approach can readily be applied to systems out of equilibrium without modification and generalized to other spectroscopies.

Abstract
Chemical solidification of construction mud is usually used to resolve environmental problems and problematic geotechnical engineering properties. This study investigated the feasibility of solidifying waste mud with fly ash (FA) based geopolymer, which was activated by calcium carbide residue (CCR) and sodium silicate solution (NS). The unconfined compressive strength (UCS) tests were carried out to optimize the CCR/NS ratio at various curing time, in addition, the tests involving water content, pH, X-ray diffractometry (XRD), scanning electron microscopy (SEM), and natural dehydration were also performed. The UCS results show that, when the CCR/NS ratio is 6:4, the optimal 28-day strength reaches 2.2MPa with the ratio of the activator CCR-NS to FA at 1:1. The binder can reduce the water content of the mud in the short term, with the best effect at pH value of 12. The microscopic compositions showed that calcium silicate hydrate (CSH) and aluminosilicate-Na hydrate (NASH) dominated cementitious products filled the pores and bonded with particles for strength development. The dehydrating cracking process of solidified mud and untreated mud was quantitatively analyzed using image processing method. The variation of cracks area ratio and water content during dehydration was studied. The solidified mud is suitable in subgrade projects, which may facilitate the diversion of large amounts of waste mud, industrial by-products CCR and FA from landfills.
Investigation of the reduction pattern of aftershocks in the Iranian plateau
Authors: Rostam Ghasem Ghorbani 
Published: October 2022

Abstract
The Iranian plateau is one of the most active and seismic areas, which is located in the Alpine-Himalayan seismic belt. This area has experienced many devastating earthquakes. The study of seismic behavior and the occurrence pattern of aftershocks of medium to large earthquakes can be important for this region. Twenty six earthquakes larger than 5 have been selected on the Iranian plateau in the last ten years to investigate their aftershocks behaviour. First the seismic parameters Mc, a and b-value were estimated by drawing the Gutenberg-Richter diagram using the maximum likelihood estimation method in ZMAP software. Then, events less than Mc were removed from the catalog. The remaining catalog was used to determine the parameters of modified Omori law for each event separately. The average value of p in Zagros and Alborz is 1.07, while this value is 0.99 for Central Iran and Kope Dagh. This can be caused by high seismic activity and rapid energy discharge by small earthquakes. Furthermore, in this study, a model for the distribution of the probability function of the waiting time of aftershock sequences of the Iranian plateau has been determined.

Authors: Hajtovic Sabastian , Samsonov Alan P. , Schmuter Gabriella , Matthews Kiran 
Published: October 2022

Abstract
Purpose
To report previously undocumented variants of the neurovascular course of the profunda brachii artery.
Methods
During routine cadaveric dissection, a unique combination of variations in the neurovascular course of the profunda brachii artery was noted in the right upper extremity of a 67-year-old female cadaver.
Results
The brachial artery was observed entirely anterior to the median nerve and its roots. The median nerve received an additional contribution from a branch of the lateral cord that communicates with the medial cord. The profunda brachii artery also took abnormal origin from the subscapular artery, rather than the brachial artery, in the same limb.
Conclusion
This report presents a unique combination of three neurovascular variations in the right upper limb of a single cadaver. Understanding variability in the course and continuation of the profunda brachii artery may assist surgeons and other interventionists in safely and effectively operating within the upper extremity.

Abstract

The aim of this study was to obtain of chan seeds oil by supercritical fluids, and to evaluate its physicochemical properties and its quality. The optimal extraction conditions were 450 bar, 80°C, and 193 min with an extraction yield of 9.21% and 62.36% recovery. The viscosity of the oil was 104.13 mPa s, and the activation energy was 2.104 KJ/mol; primary and secondary oxidation was 1.681 and 0.662. The quality of the oils was evaluated with saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), and unsaturated fatty acids (UFAs). They were also determined the atherogenicity (AI), (6.70–8.27) and thrombogenicity indices (TI), (0.075–0.094); and the hypocholesterolemic/hypercholesterolemic (HH) ratio, (19.12–33.84). The oils presented high content of fatty acids ω 3, 6, and 9, and the oxidizability was from 6.70 to 8.27, indicating good stability. The characteristics of the oil extracted were compared with the oil obtained conventionally.

Published: October 2022

Abstract
This study presented a simple and eco-friendly method to load copper nanoparticles on the surface of bacterial cellulose produced via the fermentation of coconut water by Acetobacter xylinum (Nata de coco). The Cu modification of BC surface was based on the reduction of copper (II) acetate by hydrazine under ambient conditions in a dispersion system of Nata de coco in water, which was followed by freeze-drying, affording lightweight Cu-containing cellulose aerogels. The structural features of the obtained aerogels were investigated by scanning electron microscopy with energy dispersive X-ray analysis (SEM/EDX), thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD), and nitrogen physisorption, indicating the high cellulose crystallinity, three-dimensional matrix and homogenous dispersion of Cu species on the cellulose bundles. The Cu-modified aerogel exhibited a significantly improved adsorption capacity of cyclohexane (66.4 g/g) as compared to that of pure cellulose (45 g/g). The excellent performances of 65.1-109.6 g/g were also observed for other non-polar solvents including n-hexane, toluene, ethyl acetate, dichloromethane, and chloroform depending their density.

Published: October 2022

Abstract
The neurovascular unit (NVU) is involved in the pathological changes in Alzheimer’s disease (AD). The NVU is a structural and functional complex that maintains microenvironmental homeostasis and metabolic balance in the central nervous system (CNS). As one of the most important components of the NVU, microglia not only induce BBB breakdown by neuroinflammation, the infiltration of peripheral WBCs and oxidative stress but also mediate neurovascular uncoupling by damage neurons, abnormal contraction of cerebral vessels and pericyte loss in AD. In addition, microglia-mediated dysfunction of cellular components in the NVU, such as astrocytes and pericytes, can destroy the integrity of the NVU and lead to NVU dysfunction. Therefore, we examined microglia to clarify the mechanism of NVU dysfunction in AD. Furthermore, existing medication advancements aimed at restoring the function of microglia and the NVU in AD are discussed.

Abstract

Oncogenic activation of PI3K/AKT signaling pathway, together with epigenetic aberrations is the characters of castration-resistant prostate cancer(CRPC). UHRF1 as a key epigenetic regulator, plays a critical role in prostate cancer (PCa) development, and its expression is closely associated with tumor malignancy. This present study investigated the potential regulatory relationship between AKT1 and UHRF1, and further validated thein vitroandin vivoanti-PCa efficacy of AKT phosphorylation inhibitor MK2206 in combination with abiraterone. Both UHRF1 and p-AKT aberrantly overexpressed in the abiraterone-resistant PCa cells. Further studies revealed that AKT1 protein interacts UHRF1, and AKT1 directly phosphorylates UHRF1 via the site Thr 210. MK2206 induced UHRF1 protein degradation by disrupting AKT1-induced UHRF1 phosphorylation, and then reduced the interaction between UHRF1 anddeubiquitinatingenzyme USP7, while promoted the interaction between UHRF and E3 ubiquitin protein ligase (BTRC). MK2206 significantly promoted the sensitivity of abiraterone-refractory PCa cells and xenografts to abiraterone by downregulating the levels of UHRF1, and reversed the transdifferentiation of NEPC (SYP and NCAM1), even activated cell senescence (p21 upregulation) and cell apoptosis (cleaved-PARP). Altogether, our present study for the first time revealed a novel molecular mechanism of abiraterone resistance through PI3/AKT-UHRF1 pathway, and provided a novel therapeutic modality by targeting PI3/AKT1 to promote the drug sensitivity of abiraterone in PCa patients.

Abstract

ObjectiveCombined transcranial magnetic stimulation and electroencephalography (TMS-EEG) is an effective way to evaluate neurophysiological processes at the level of the cortex. To further characterize the TMS-evoked potential (TEP) generated with TMS-EEG, beyond the motor cortex, we aimed to distinguish between cortical reactivity to TMS versus non-specific somatosensory and auditory co-activations using both single-pulse and paired-pulse protocols at suprathreshold stimulation intensities over the left dorsolateral prefrontal cortex (DLPFC).MethodFifteen right-handed healthy participants received six blocks of stimulation including single and paired TMS delivered as active-masked (i.e., TMS-EEG with auditory masking and foam spacing), active-unmasked (TMS-EEG without auditory masking and foam spacing) and sham (sham TMS coil). We evaluated cortical excitability following single-pulse TMS, and cortical inhibition following a paired-pulse paradigm (long-interval cortical inhibition (LICI)).ResultsRepeated measure ANOVAs revealed significant differences in mean cortical evoked activity (CEA) of active-masked, active-unmasked, and sham conditions for both the single-pulse (F(1.76, 24.63)=21.88 , p<0.001, η2=0.61) and LICI (F(1.68, 23.49)=10.09 , p<0.001, η2=0.42) protocols. Furthermore, global mean field amplitude (GMFA) differed significantly across the three conditions for both single-pulse (F(1.85, 25.89)=24.68 , p<0.001, η2=0.64) and LICI (F(1.8, 25.16)=14.29 , p<0.001, η2=0.5). Finally, only active LICI protocols but not sham stimulation ([active-masked (0.78±0.16, P<0.0001)], [active-unmasked (0.83±0.25, P<0.01)]) resulted in significant signal inhibition.ConclusionWhile previous findings of a significant somatosensory and auditory contribution to the evoked EEG signal is replicated by our study, an artifact attenuated cortical reactivity can reliably be measured in TMS-EEG signal with suprathreshold stimulation of DLPFC. Artifact attenuation can be accomplished using standard procedures and even when masked, the level of cortical reactivity is still far above what is produced by sham stimulation.SignificanceOur study illustrates that TMS-EEG of DLPFC remains a valid investigational tool.

Abstract

Two new species of Monogenoidea (Telethecium tiquira n. sp. and Guamacotyle forficata n. gen. n. sp.) from the nasal cavities of Bryconops melanurus (Bloch) are described from the Brazilian Eastern Amazon. Telethecium tiquira n. sp. is characterized by possessing a male copulatory organ (MCO) with two circular sclerotized brims on the base, a coiled tubular shaft having 1 ½ counterclockwise rings; an accessory piece with enlarged base, pincer-shaped at the distal portion; asclerotized calyx-shaped vaginal vestibule; and hooks with proximal shank dilatation comprising 3/4 of the shank length. The new species also differs from the congeners by lacking the protruding bag located at level of the terminal male genitalia.The monotypic Guamacotyle n. gen. is characterized by having a MCO with counterclockwise rings; an accessory piece non articulated to MCO, clamp-shaped; a sclerotized vagina with sinistrolateral aperture; ventral anchors larger than dorsal anchors; and hooks with similar sizes. The proposal of the new genus is also supported by phylogenetic analysis based on 28S rDNA, which supports the close relationship of Guamacotyle n. gen. with Cacatuocotyle papilionis and Diaphorocleidus spp., all parasites of Neotropical fishes.
Study of the photovoltaic properties of Cs and Cl co-doped FAPbI 3 based on first principles

Published: October 2022

Abstract

Formamidine lead iodide chalcogenide (FAPbI3) is often used as a light-absorbing layer in solar cells to alleviate the energy crisis because of its own good photovoltaic properties.however, the lack of stability is also an obstacle to the current development. It has been found that doping with different kinds of elements at different sites can enhance its stability and improve the photoelectric conversion efficiency of solar cells. In this paper, the geometry, electronic structure and optical properties of FA1 − xCsxPbI3−yCly were calculated using Cs and Cl co-doped with FAPbI3 using the first nature principle. The analysis revealed that the Goldschmidt factors of the doped system were between 0.962 and 0.974, indicating that the system could maintain a stable chalcogenide structure, and the doped system had lower energy and more stable structure. By calculating the energy bands, it is found that the doped ions have a more pronounced effect on the increase of the dispersion at the bottom of the conduction band than the decrease of the dispersion at the top of the valence band of the system, and the reduction of the effective mass of carriers is more favorable for transport. As for the optical properties, the right amount of doping is favorable to the improvement of light absorption, while the excess doping shortens the light absorption range and weakens the light absorption effect, in which FA0.875Cs0.125PbI2.958Cl0.125 has the largest light absorption coefficient. It is shown that the photoelectric properties of chalcogenide FAPbI3 can be effectively modulated by the co-doping of Cs and Cl, which can provide theoretical reference for the precise preparation of more efficient solar cells experimentally.
Threats to the thermal mineralized waters used for therapeutic purposes in Jordan
Authors: Salameh Elias 
Published: October 2022

Abstract
Although Jordan is a country with very limited water resources, the country is rich in its thermal mineralized water possessing curative properties, historically used for the therapy of a variety of ailments. Due to the country’s increasing water demand resulting from population growth, urbanization, and industrialization, extractions from the groundwater sources feeding the thermal mineralized springs has started to affect negatively the discharged quantities from the springs. In addition, urbanization, mining activities, over-exploited groundwater resources in general and severe drop in the level of the Dead Sea is leading to declining discharge of springs in general, and thermal mineralized in special, deteriorating water quality and contamination by human activities. In this article, the current quantitative and qualitative situation of the thermal mineralized springs is given and the threats to their discharges and quantities are discussed. In addition, some water policy changes and measures are suggested to conserve these therapeutic waters for the use of generations to come and to alleviate their depletion and quality deterioration on the social and economic state of Jordan.

Published: October 2022

Abstract

Background
The P300 wave shows a prolonged latency and reduced amplitude in patients with cognitive deficits. However, no study correlated P300 wave changes with the cognitive performance of patients with cerebellar lesions. We aimed to determine if the cognitive status of these patients is associated with P300 wave alterations.
Methods
We recruited 30 patients with cerebellar lesions from the wards of the N.R.S. Medical College, Kolkata, in West Bengal (India). The Kolkata Cognitive Screening Battery tasks and the Frontal Assessment Battery were used to assess the cognitive status and the International Cooperative Ataxia Rating Scale for cerebellar signs. We compared the results with the normative data of the Indian population.
Results
Patients had P300 wave alterations, with a significant increase in latency and a non-significant trend in amplitude. In a multivariate model, P300 wave latency was positively associated with the ICARS kinetic subscale (p = 0.005) and age (p = 0.009), regardless of sex and years of education. In the model that included cognitive variables, P300 wave latency was negatively associated with performance in phonemic fluency (p = 0.035) and construction (p = 0.009). Furthermore, P300 wave amplitude was positively associated with the FAB total score (p < 0.001).
Conclusion
Patients with cerebellar damage had an increase in latency and a decrease in the amplitude of the P300 wave. These P300 wave alterations were also associated with worse cognitive performance and some of the subscales of ICARS, reinforcing that the cerebellum has both motor and cognitive and affective functions.
WITHDRAWN: Serum metabolomics probes the molecular mechanism of action of acupuncture on metabolic pathways related to glucose metabolism in obese PCOS: a randomized controlled trial

Published: October 2022

Abstract
Background & aims:
Polycystic ovary syndrome (PCOS) is a common endocrine syndrome, and obesity is the most common clinical manifestation of PCOS. Acupuncture therapy has shown great success in the treatment of PCOS, but the mechanism of acupuncture therapy in the treatment of patients with PCOS remains unclear. The biological mechanism of acupuncture therapy is vastly different from western drugs; thus, we aimed to compare the key metabolic pathways, including citric acid and glucose metabolism in acupuncture therapy.
Methods
Sixty patients with obese polycystic ovary syndrome were randomly distributed into three groups; patients receiving (1) acupuncture treatment alone, (2) conventional western medicine treatment, and (3) acupuncture combined with western medicine treatment. A targeted metabolomics approach was used to identify small molecules and metabolites related to glucose metabolism in the serum of each group, and ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) was used to analyze different metabolic fractions.
Results
Acupuncture treatment reduced mitochondrial dysfunction and oxidative damage in the liver, and decreased insulin resistance in PCOS patients by reducing the production of many metabolites involved in the tricarboxylic acid cycle (TCA cycle), such as citric acid and succinic acid. Acupuncture therapy also regulated glycolysis and gluconeogenesis pathways upstream of the TCA cycle. Activating the enzymes involved in the key glycolytic pathways and reducing the production of lactate improved the pathological conditions (impaired energy metabolism, insulin resistance, and obesity) in patients with PCOS.
Conclusions
Acupuncture treatment improved the levels of sex hormones and energy metabolism by downregulating the TCA cycle activity and modulating glycolytic and gluconeogenic pathways. However, the intervention effects on the metabolic pathways were different between patients receiving combination therapy and patients receiving acupuncture therapy alone, suggesting that the dominant modulatory effect of western drugs may largely conceal the efficacy of acupuncture intervention.
