Published: December 2023

AbstractIt has been suggested that conscious experience is linked to the richness of brain state repertories, which change in response to environmental and internal stimuli. High-level sensory stimulation has been shown to alter local brain activity and induce neural synchrony across participants. However, the dynamic interplay of cognitive processes underlying moment-to-moment information processing remains poorly understood. Using naturalistic movies as an ecological laboratory model of the real world, here we investigate how the processing of complex naturalistic stimuli alters the dynamics of brain network interactions and how these in turn support information processing. Participants underwent fMRI recordings during movie watching, scrambled movie watching, and resting. By measuring the phase-synchrony between different brain networks, we analyzed whole-brain connectivity patterns. Our finding revealed distinct connectivity patterns associated with each experimental condition. We found higher synchronization of brain patterns across participants during movie watching compared to rest and scrambled movie conditions. Furthermore, synchronization levels increased during the most engaging parts of the movie. The synchronization dynamics among participants were associated with suspense; scenes with higher levels of suspense induced greater synchronization. These results suggest that processing the same high-level information elicits common neural dynamics across individuals, and that whole-brain functional connectivity tracks variations in processed information and subjective experience.

Published: December 2023

AbstractThe segmentation and extraction on color features can provide useful information for many different application domains. However, most of the existing image processing algorithms on feature extraction are gray image-based and consider only one-dimensional parameters. In order to carry out a fast and accurate color feature extraction, this paper proposes a color extraction algorithm by segmentation that is called a color extraction algorithm This algorithm is compared under different color distribution situations, and the extraction effect on color is also shown by the combination of the segmentation and feature extraction algorithms. Experimental results show that such segmentation algorithm has some advantages for color segmentation. In the fuzzy color image preprocessing, this paper gives the location method of region of interest. Moreover, compared with other existing extraction algorithms, the presented segmentation extraction algorithm in this paper not only has higher accuracy, shorter extraction time and stronger anti-interference ability, but also has better effect on more divergent color edge. Experimental evaluation of the proposed color extraction algorithm demonstrates dominance over existing algorithms for feature extraction. These researches in this paper provide a new way of thinking for color feature extraction by segmentation, which has an important theoretical references and practical significance.

Published: December 2023

AbstractTo address the problem of excessive local secondary stripping between adjacent mining areas in open pit mines caused by internal row raising, a multivariate function was fitted to the model of the main mining seam of Zhundong open pit coal mine in Xinjiang, and the different locations of the end gang of the second mining area were divided into multiple sections at certain step sizes and calculated by integration, resulting in stripping ratios for each section, which were fitted to a stripping ratio curve. The optimal location of the mining area boundary was found to be 55 m westward offset from the mining area boundary in the inner row of the raised section, and numerical simulations based on the strength reduction method were applied to analyse the slope stability of the end gang at this location. The results of the study show that the analysed slope meets the stability requirements and the optimised new boundary avoids the stripping of approximately 65,837,376 m3 of economically unreasonable section.

AbstractThis study was the first-ever attempt to apply MIL-68 (Ga) in developing an analytical method. The method extracts and preconcentrates some parabens from mouthwash and hydrating gel samples. The variable extraction parameters were optimized, and the figures of merit were documented. Avogadro software was used besides discussing intermolecular interactions to clarify the absorption process. ComplexGAPI software was also exploited to assess the greenness of the method. After the derivatization of the parabens using acetic anhydride in the presence of sodium carbonate, sodium chloride was added to the solution and vortexed to dissolve. A few milligrams of MIL-68 (Ga) were added into the solution and vortexed. Centrifugation separated the analyte-loaded absorbent, which was treated with mL volume of methanol through vortexing for desorption aim. A few microliters of 1,2-dibromoethane were merged with the methanolic phase and injected into a sodium chloride solution. One microliter of the extracted phase was injected into a gas chromatograph equipped with a flame ionization detector. High enrichment factors (200–330), reasonable extraction recoveries (40–66%), wide linear ranges (265–30,000 µg L−1), and appreciable coefficients of determination (0.996–0.999) were documented. The applicability of dispersive solid phase extraction for extracting polar analytes, imposing no additional step for performing derivatization, the capability of MIL-68 (Ga) for the absorption of both derivatized and non-derivatized parabens, the use of only 10 mg absorbent, and one-pot synthesis besides no high temperature or long reaction time in the sorbent provision are the highlights of the method.

Die Therapie von Angststörungen um 1900. Hermann Oppenheim
(1858–1919) und seine frühen Innovationen
Authors: Moenikes Nina C. , Steinberg Holger 
Published: December 2023

ZusammenfassungAls nervenärztlicher Lehrer und Lehrbuchautor erfuhr Oppenheim
zunächst große Anerkennung. Mit seiner Monografie zur
traumatischen Neurose (1892), die er als Folge organischer bzw. molekularer
Veränderungen ansah, geriet er immer mehr in Kritik und Ablehnung
vorwiegend seitens deutscher Kollegen. Seine jüdische Herkunft spielte
hierbei eine Rolle. Kaum historische Beachtung hingegen findet bislang
Oppenheims Auseinandersetzung mit dem Phänomen der Angst, welches sich
zu seiner Zeit noch als ein wenig definiertes pathologisches
Störungsbild darstellt. Oppenheim betrachtet in seinen Arbeiten
v. a. der Jahre nach 1900 Angststörungen als ätiologisch
multifaktoriell bedingte Krankheitserscheinung und gesteht ihnen einen
syndromalen Charakter zu. Therapeutisch orientiert er sich nicht nur an
gängigen Behandlungsmethoden wie der Diätetik oder der
Psychoanalyse, sondern sieht den Patienten als zu respektierendes,
wertzuschätzendes Individuum. Daraus leitet er selbstentwickelte
psychotherapeutische Behandlungsmethoden ab, die Ähnlichkeit mit
heutigen Verfahren der kognitiven Verhaltenstherapie aufweisen, wie die
Ablenkung von angstauslösenden Gedanken, die Orientierung auf
persönliche Ressourcen des Patienten oder die Konfrontation mit der
Angstsituation. Oppenheims Beiträge zu den Angststörungen
erweisen sich als für ihre Zeit innovativ.

AbstractFew studies demonstrated a percentage decrease in the estimated glomerular
filtration rate (eGFR) at a single time and the rate of hypoaldosteronism after
adrenalectomy for primary aldosteronism (PA). Our aim was to investigate the
evolution of renal function and the hypoaldosteronism risk after adrenalectomy
for PA. Aldosterone, renin, eGFR, and electrolyte levels were determined before
and at 1 week, 1, 3 and 6 months after unilateral adrenalectomy in 94 PA
patients (40 men and 54 women). The main outcome was the postoperative eGFR
decline using analysis of covariance with the preoperative eGFR as a covariate.
eGFR decreased during first postoperative week compared to 3 months before
surgery. During the first 6 months, eGFR remained stable at similar levels to
the first week after surgery. Age (p=0.001), aldosterone levels
(p=0.021) and eGFR 3 months before surgery
(p+<+0.0001) had a significant correlation with eGFR
during first postoperative week. High aldosterone levels at diagnosis were
correlated with decline in renal function in the univariate model
(p=0.033). In the multivariate analysis, aldosterone levels at diagnosis
had a tendency to be an independent predictor of renal function after surgery
(p=0.059). Postoperative biochemical hypoaldosteronism was diagnosed in
48% of the cases after adrenalectomy, but prolonged hyperkalemia
occurred in only 4 cases (4.5%). Our findings showed a decrease of eGFR
after unilateral adrenalectomy for PA. Additionally, aldosterone levels at
diagnosis correlated with postoperative renal function. Postoperative
biochemical hypoaldosteronism occurred in almost half of the patients, but
prolonged hyperkalemia with fludrocortisone replacement was less frequent.

Authors: Elizabath Ansana , Varathan Kalidasan 
Published: December 2023

Abstract
Objective Hemiparesis occurs when a stroke causes paresis on the body, contralateral to the lesioned brain. In poststroke patients, upper limb impairments induce functional restrictions. Arm ability training is a unilateral treatment for mild arm paresis. We evaluated the effectiveness of arm ability training on functional mobility and dexterity in hemiparetic subjects
Materials and Methods Forty-two hemiparetic subjects were selected by convenient sampling technique. The subjects were given 40 minutes of arm ability training and 20 minutes of conventional physiotherapy daily, five sessions a week extending for 4 weeks. Functional mobility was assessed through wolf motor function test (WMFT) and dexterity by box and block test (BBT).
Results The pre- and post-test scores were evaluated by paired t-test using SPSS software after 4 weeks of training period subjects showed much improvement for the BBT (mean ± standard deviation [SD]: 20.31 ± 4.075 vs. 23.79 ± 4.291), functional ability of WMFT (mean ± SD: 45.38 ± 3.615 vs. 54.07 ± 3.790), time of WMFT (mean ± SD: 479.29 ± 117.79 vs. 434.4 ± 116.455), the strength of WMFT was (mean ± SD: 2.95 ± 0.731 vs. 3.9 ± 0.759), and grip strength of WMFT (mean ± SD: 2.9 ± 1.559 vs. 4.21 ± 1.539), all variables indicating statistical significance (p < 0.05).
Conclusion Arm ability training proved effective in improving functional mobility and dexterity in hemiparetic subjects.
Retroperitoneal Colon Perforation with Review of Retroperitoneal Anatomic Relationships: Case Series with Review of Literature
Authors: Satoh Shina , Hwang Albert , Berliner Leonard 
Published: December 2023

AbstractWe present two cases of iatrogenic retroperitoneal perforation involving the ascending and descending colon. The unique imaging findings in these two cases demonstrate potential routes of communication for air originating in the retroperitoneum. In context of these cases, we review the clinical presentation, management, and anatomic features of retroperitoneal perforation. Along with clinical history, an understanding of retroperitoneal anatomic relationships can aid radiologists in identifying the origin of perforation.
HybridDenseU-Net: learning a multi-scale convolution and dense connectivity CNN for inverse imaging problems
Authors: Zhang Baojie , Wang Zichen , Chen Xiaoyan , Wang Qian , Xie Na , Liu Lili 
Published: December 2023

Abstract
Inverse imaging problems (IIPs) is a cutting-edge technology which is part of the nonlinear inverse problem, the solution approaches to which have placedattention on deep learning recently. This paper proposes a unique learning-based framework for IIPs, referred to as HybridDenseU-Net, which takes U-Net as the backbone and optimizes the encoder as a two-branch feature extraction module. Compared to the direct skip-connection in conventional U-Net, dense connections are introduced to merge features between feature maps with the same dimension and construct multi-scale content in the decoder. The validation of HybridDenseU-Net is carried out by a case study of electrical impedance tomography, which is of typical nonlinear IIP. The results illustrate that HybridDenseU-Net has root mean square error of 3.0867 and structural similarity of 0.9846, which are significantly better than some state-of-the-art deep learning-based frameworks. It has been proven that this work could provide a promising idea for future research on learning-based image reconstruction methods.

Published: December 2023

Abstract

Objective. X-ray spectral computed tomography (CT) allows for material decomposition (MD). This study compared a one-step material decomposition MD algorithm with a two-step reconstruction MD algorithm using acquisitions of a prototype CT scanner with a photon-counting detector (PCD). Approach. MD and CT reconstruction may be done in two successive steps, i.e. decompose the data in material sinograms which are then reconstructed in material CT images, or jointly in a one-step algorithm. The one-step algorithm reconstructed material CT images by maximizing their Poisson log-likelihood in the projection domain with a spatial regularization in the image domain. The two-step algorithm maximized first the Poisson log-likelihood without regularization to decompose the data in material sinograms. These sinograms were then reconstructed into material CT images by least squares minimization, with the same spatial regularization as the one step algorithm. A phantom simulating the CT angiography clinical task was scanned and the data used to measure noise and spatial resolution properties. Low dose carotid CT angiographies of 4 patients were also reconstructed with both algorithms and analyzed by a radiologist. The image quality and diagnostic clinical task were evaluated with a clinical score. Main results. The phantom data processing demonstrated that the one-step algorithm had a better spatial resolution at the same noise level or a decreased noise value at matching spatial resolution. Regularization parameters leading to a fair comparison were selected for the patient data reconstruction. On the patient images, the one-step images received higher scores compared to the two-step algorithm for image quality and diagnostic. Significance. Both phantom and patient data demonstrated how a one-step algorithm improves spectral CT image quality over the implemented two-step algorithm but requires a longer computation time. At a low radiation dose, the one-step algorithm presented good to excellent clinical scores for all the spectral CT images.
Research perspectives on the structure-property relationship of polyaromatic pyrene-based chalcone derivatives as dye-sensitizers in DSSC applications

Published: December 2023

Abstract
Photovoltaic studies in DSSC have continued to be fascinated by chalcone derivatives because of their straightforward synthesis, green synthetic process and low toxicity properties using Claisen-Schmidt condensation method. In this report, the implementation of the newly synthesized pyrenyl chalcone derivatives, Py1 and Py2 as dye-sensitizers and the characterization studies are further discussed. The grown crystals are characterized via several spectroscopic analyses such as ATR, 1H and 13C NMR and UV–vis analyses. The UV–vis analysis shows a lower energy gap in Py1 (2.79 eV) in comparison to Py2 (2.90 eV) which further indicates better flow of charge transfer. The analysis of crystal packing reveals the arrangement of head-to-head by intermolecular π—π contacts and head-to-tail via intermolecular C–H···O interactions in Py1 and Py2, respectively. The intermolecular interactions act to stabilize the crystal structure and further improve the charge transfer within the dyes and enhancement of DSSC efficiency. In electrochemical analysis using cyclic voltammetry (CV), Py1 and Py2 are found in the suitable HOMO and LUMO energy levels which confirms their applicability as photosensitizer materials. After the fabrication process, DSSC layers are continued for FESEM and EDX analyses before proceeding for the performance study. The Py1 with D-π-A architecture has significantly revealed a higher efficiency than D-π-D structure of Py2.
The digitalisation, dematerialisation and decarbonisation of the global economy in historical perspective: the relationship between energy and information since 1850
Authors: Fouquet Roger 
Published: December 2023

Abstract
To better understand the processes of digitalisation, dematerialisation and decarbonisation, this paper examines the relationship between energy and information for the global economy since 1850. It presents the long run trends in energy intensity and communication intensity, as a proxy for total information intensity. The evidence suggests that, relative to GDP, global economic production has been reducing energy and increasing information use since 1913. The analysis indicates that it initially required little information to replace energy in production and that the ability to substitute away from energy and towards information has been declining. The result implies that the global economy is now reducing energy and increasing information at a substitution rate of 0.2 kB per kWh of conserved energy or 0.8 GB per tonne of carbon dioxide mitigated. As the price ratio of energy to information is currently higher than this marginal rate of substitution, there are incentives to further substitute information for energy. However, one conclusion is that (without the long run escalation of carbon prices) substitution away from energy and towards information is likely to cease within the next few decades and, beyond that, digitalisation will play a declining role in the decarbonisation process.
Transition to chaos in extended systems and their quantum impurity models
Authors: Prasad Mahaveer , Yadalam Hari Kumar , Kulkarni Manas , Aron Camille 
Published: December 2023

Abstract
Chaos sets a fundamental limit to quantum-information processing schemes. We study the onset of chaos in spatially extended quantum many-body systems that are relevant to quantum optical devices. We consider an extended version of the Tavis–Cummings model on a finite chain. By studying level-spacing statistics, adjacent gap ratios, and spectral form factors, we observe the transition from integrability to chaos as the hopping between the Tavis–Cummings sites is increased above a finite value. The results are obtained by means of exact numerical diagonalization which becomes notoriously hard for extended lattice geometries. In an attempt to circumvent these difficulties, we identify a minimal single-site quantum impurity model that successfully captures the spectral properties of the lattice model. This approach is intended to be adaptable to other lattice models with large local Hilbert spaces.
The Influence of Game-Enhanced Communication on EFL Learners’ Pragmatic Competence in Compliment Responses
Authors: Zhang Ying 
Published: December 2023

Abstract
A small number of studies have explored the effects of digital gaming on second/foreign language (L2) pragmatic competence. However, the effectiveness of massively multiplayer online role-playing games (MMORPGs) germane to L2 pragmatic development remains unclear because most game-mediated pragmatics studies have focused on educational games. Adopting the interactionist approach, this pretest-immediate-posttest-delayed-posttest study investigated the influence of an MMORPG on L2 learners’ pragmatic competence in compliment responses. Specifically, 105 English-as-a-foreign-language learners from a university in China interacted with L1-English-speaking players in World of Warcraft for four weeks. Unlike most studies that have conducted discourse completion tasks for data collection, compliment responses were gathered through computer-mediated communication with L1-English-speaking interlocutors on WeChat. Results showed that the learners tended to deny compliments on the pretest, whereas they preferred to accept praise on the immediate and delayed posttests. Implications for language policy-making and teaching are discussed regarding the usefulness of MMORPGs for learners who are not immersed in the environment of the target language or have few opportunities to go abroad to experience various social contexts in an L2.
