Authors: Giti Rashin , Mosallanezhad Sina 
Published: November 2024

Background and aim
Achieving the aesthetic standards in tooth-colored restorative materials requires close attention to their color, translucency, and resistance to discoloration. This study aimed to evaluate the effect of sintering temperature on color stability and translucency in zirconia systems with low, high, and ultra-high translucencies.

Methods
This experimental study was conducted on 60 zirconia disks with low, high and ultra-high translucencies (n = 20 per group), each group divided into subgroups to be sintered at either 1450°C or 1550°C (n = 10 per subgroup). Baseline color and translucency parameters were measured, the specimens were then immersed in coffee solution for 30 days, and the measurements were repeated post-immersion. Changes in color (ΔE) and translucency (ΔTP) were calculated via CIELAB formula and compared by using two-way ANOVA and Tukey’s post hoc test (α = 0.05).

Results
Results of two-way ANOVA showed that the ΔE was significantly different among the three zirconia translucencies (P<0.001), but no significant difference was found between the two sintering temperatures (P = 0.712). Additionally, the interaction between zirconia type and sintering temperature was not statistically significant for ΔE (P = 0.264). The low-translucency group showed significantly greater ΔE than the high-translucency and ultra-high-translucency groups (P<0.05), while the high- and ultra-high-translucency groups were not significantly different in this regard (P>0.05). Regarding the ΔTP, two-way ANOVA showed that the difference was not statistically significant either among the three zirconia types (P = 0.4430) or between the two sintering temperatures (P = 0.4544). Nor was the interaction between zirconia type and sintering temperature statistically significant (P = 0.5505).

Conclusion
It was concluded that sintering temperature had no effect on color and translucency changes after immersion in coffee. Whereas zirconia type significantly affected the color changes after immersion in coffee; with the higher-translucency zirconia types being significantly more color-stable than the low-translucency zirconia.

Joseph Jacob Gumprecht, ein jüdischer Mediziner im Zeitalter der Aufklärung: blockierte Universitätskarriere, geöffnete Zivilgesellschaft
Authors: Schlumbohm Jürgen 
Published: November 2024

Abstract
Joseph Jacob Gumprecht, MD, 1772–1838, is the first Jew known as a university lecturer (Privatdozent) at a German university. This biographical article analyses the network of family, friends and colleagues, in which his life course was embedded. It shows his achievements, failures and partial successes. When his career at the University of Göttingen was blocked, he moved to Hamburg, practised as a physician and man-midwife. He was not successful economically, and his family broke up. But he made noteworthy contributions to the emergent discipline of obstetrics, both as an author and editor of periodicals. Moreover, he was active in establishing associations in several fields: for the profession of medical men, and in the context of the Jewish reform movement. Gumprecht’s example shows that German Jews not just integrated themselves into the middle class, but that they actively contributed to shaping civil society and the culture of the middle class.
Hokhmat ha-Nefesh
: Soul and Dream, from Eleazar of Worms to Renaissance Italy
Authors: Abate Emma 
Published: November 2024

Abstract
This article examines the traditions of copying and reading a medieval Ashkenazi treatise, Hokhmat ha-Nefesh (»Wisdom of the Soul«) by Eleazar of Worms (1176–1238) in Renaissance Rome. It delves into a manuscript copied in 1515 by Jewish scholar Elias Levita (1469–1549), commissioned by Levita’s patron, Neoplatonist and Hermetic scholar Egidio da Viterbo (1469–1532). In addition to copying the text, Egidio had Jewish interpreters translate Hokhmat ha-Nefesh into vernacular Italian. The treatise discusses the heavenly nature of the soul, its connections with the angelic world, its prophetic abilities, and its fate and retribution in the afterlife. What role did this Ashkenazi text play in the early modern tradition? How can this text be seen as a testament to kabbalistic perspectives in Renaissance Italy? How did Egidio’s collaborators handle their scribal and translation tasks, and the relationship between the Hebrew original and the vernacular translation of Hokhmat ha-Nefesh? This essay addresses these questions.
Exploring the properties of multivariable Hermite polynomials in relation to Apostol-type Frobenius–Genocchi polynomials
Authors: Wani Shahid Ahmad , Shah Tafaz Ul Rahman , Ramírez William , Cesarano Clemente 
Published: November 2024

Abstract
This work presents a general framework that innovates and explores different mathematical aspects associated with special functions by utilizing the mathematical physics-based idea of monomiality. This study presents a unique family of multivariable Hermite polynomials that are closely related to Frobenius–Genocchi polynomials of Apostol type. The study’s deductions address the differential equation, generating expression, operational formalism, and other characteristics that define these polynomials. The affirmation of the controlling monomiality principle further confirms their mathematical foundations. In addition, the work proves recurrence relations, fractional operators, summation formulae, series representations, operational and symmetric identities, and so on, all of which contribute to our knowledge of these complex polynomials.

The Evaluation System of Global Cinematic Strength and the Advancement of Chinese Films
Authors: Tan Zheng , Zhang Yan 
Published: November 2024

Abstract
The goal of transforming China into a country with leading cinematic strength has long been proposed, yet the criteria for defining a country with leading cinematic strength have remained unclear. Drawing from the current global film industry structure and evaluation systems for strength in other fields, the evaluation system of global cinematic strength should encompass the two primary indicators of domestic and international influence, six secondary indicators, such as industry base and scale, and twenty tertiary indicators, such as the number of cinemas and screens and film production. Under this evaluation system, only the United States currently qualifies as a country with leading cinematic strength, while China and India show a potential for development. China should enhance support for young filmmakers, increase overseas promotion, and position itself as a key target market for films from developing countries to facilitate its transformation from a major film country to a country with leading cinematic strength.

Authors: Bredtmann Julia , Höckel Lisa Sofie 
Published: November 2024

Zusammenfassung
In der bestehenden Literatur werden langfristig positive Effekte von Maßnahmen der beruflichen Weiterbildung auf verschiedene Arbeitsmarktindikatoren beschrieben. Unklar ist bislang jedoch, inwiefern die Förderung der beruflichen Weiterbildung zur Arbeitsmarktintegration von Geflüchteten beitragen kann. Julia Bredtmann und Lisa Sofie Höckel untersuchen daher anhand der Sondersituation der Fluchtmigration seit 2015 mit Hilfe administrativer Daten und einer Propensity-Score-Methode die kurz- und mittelfristigen Effekte von Weiterbildungsmaßnahmen auf die Arbeitsmarktintegration von Geflüchteten. Es zeigt sich, dass sich die Teilnahme an einer Weiterbildungsmaßnahme positiv auf die Beschäftigungswahrscheinlichkeit und die Höhe des erzielten Lohns auswirkt. Dabei variieren die Effekte für verschiedene Personengruppen, beispielsweise in Bezug auf das Geschlecht sowie das Alter der Geflüchteten.

Authors: Wzorek Anna 
Published: November 2024

The article analyses „The Ants" by Maria Pawlikowska-Jasnorzewska, reckoned, apart from ,,A Woman of Wonder", one of the best, and at the same time the most popular dramas of this interwar poetess. In the analysis conducted in terms of the history of literature, attention was paid to (as indicated by the title of the drama) social issues present in this literary work. The social issues are present in the two parallel plots - the metaphorical one (in Act l and Act III) and the realistic one (in Act II). In closing conclusions, the attention was drawn to the fact that Pawlikowska, introducing the reader to the world of insects and the reality of humans, extended the scope of the addressed issues. The playwright tackled the question of the totalitarianism - a system constraining the individual, encroaching on the most intimate areas of life and degrading the existing values. In addition, the author expressed her opinion on love and maternity.

Authors: Hooker Roderick S. , Bruza-Augatis Mirela , Puckett Kasey , Kozikowski Andrzej 
Published: November 2024

Background:
For over half a century, physician assistants/associates (PAs) in orthopedics have been a source of specialized medical and surgical labor. Given the increasing demand for orthopedic surgeons and the concurrent growth of PAs, we analyzed the characteristics of PAs in orthopedics to understand how they compare with PAs across all other medical and surgical roles in the United States.

Methods:
In this national cross-sectional study, we used 2022 PA workforce data from the National Commission on the Certification of Physician Assistants. Our investigation included descriptive and bivariate data assessing PAs in orthopedics versus all other medical fields on various factors related to demographics, education/training, practice characteristics, and other important traits.

Results:
In this analysis, 12,599 (10.7%) of 117,748 board certified PAs who responded working in a clinical specialty indicated participating in orthopedics in 2022. The proportion of PAs practicing in orthopedics increased by nearly 39% from 2015 to 2022. Slightly more than half of PAs in orthopedics were female (52.9%), and the average age was 38 years. Most (55.3%) PAs in orthopedics work in offices and clinics, and a third (37.0%) are hospital based. PAs in orthopedics earn about 9% more than all other PAs; over half (50.5%) report working more than a 40-hour week. PAs in orthopedics report less burnout than their counterparts and are less likely to leave their principal clinical position.

Conclusions:
Orthopedics ranks as the third largest specialty for PAs in the United States. Furthermore, the number of PAs selecting to practice in orthopedics has escalated during orthopedic surgeon shortages. The economics and diverse roles emerging among PAs in orthopedics suggest that this specialty may be expanding.
Research on Damage Characterization of Rock-filled Concrete with Defects Using Super Absorbent Polymer
Authors: Liu Yunke , Wang Guoji , Yang Tao , Qiao Haoyang , Yu Lei , Ren Tao 
Published: November 2024

Abstract

Rock-filled concrete (RFC) construction technology is to construct a force-transferring skeleton with large-size rocks, and to use self-compacting concrete (SCC) as the filling and bonding material, in which the defects with different distributions and sizes contained in SCC are often the key factors determining the mechanical properties and damage behaviors of RFC. In this research, by utilizing the excellent properties of super absorbent polymer (SAP), such as water absorption and expansion and dehydration shrinkage, non-introduction of impurities, and not easy suspension or settlement in concrete, RFC and SCC specimens with different numbers and sizes of defects were precisely prepared and subjected to unconfined uniaxial compression physical tests. The effects of porosity and pore aperture on the compressive strength and damage pattern of the specimens were studied. The mechanical behavior of the defective concrete specimens under compressive loading was analyzed from a microscopic perspective by using a combination of physical tests and numerical simulation using the Realistic Failure Process Analysis (RFPA) method to reveal the internal damage phenomenon and damage destabilization mechanism of RFC and SCC. The results show that: SAP material can accurately construct concrete specimens with stable and uniform defects; under the same porosity and aperture, the compressive strength of RFC is greater than that of SCC; the compressive strength of the specimen decreases linearly with the growth of porosity for the same aperture, the compressive strength of the specimen decreases with the increase of aperture for the same porosity and the trend tends to be flat, and the sensitivity of the compressive strength to porosity is higher than that of aperture. In addition, it was found that the internal penetrating shear damage during the fracturing process of SCC was the core cause of the overall damage. For RFC, the tensile fracture that penetrated through the force transmission skeleton of the stacked rock was the key factor causing the overall instability.

Published: November 2024

Abstract

A full-control design can significantly improve drug release and cell proliferation for tissue engineering applications in medicine. The present investigation encompassed a molecular docking study which was performed to investigate the interaction of selected active ligand (coumarin) with the L929 mouse fibroblast cell line protein as the receptor. After that, the coumarin was extracted from the roots of p.ferulacea and its subsequent nanoencapsulation with polycaprolactone, employing the coacervation technique to achieve a narrow distribution of nano particle sizes. Subsequently, the electrospinning technique was utilized to apply a second coating to the nano-encapsulated coumarin. Polyvinyl alcohol and gelatin compounds were used to produce electrospun nanofibrous scaffolds for their similarity to the extracellular matrix (ECM). This coordinated nano platform aimed to assess its effectiveness in regulating drug release, evaluate its biocompatibility, and examine its impact on L929 cell proliferation according to the Lag and Log phases of their growth. In silico analyses demonstrated significant interactions and high binding energy values between the coumarin ligand and essential residues of the L929 mouse fibroblast proteins. The results of the experiments were checked using analyses of 1H NMR, FTIR, UV, SEM, mechanical properties, DSC, HRTEM, and HPLC. The biological effects and cell proliferation were conducted employing the MTT method (up to 5 days). Notably, no cytotoxicity was detected throughout the assessment. In this way, it is feasible to create a synergistic nano delivery system by delaying the release of the drug into account the timing of distinct cell lines' development phases.

Published: November 2024

Abstract

The progesterone receptor (PR) is a steroid-responsive nuclear receptor with two isoforms: PR-A and PR-B. Disruption of PR-A:PR-B signaling is associated with breast cancer through interactions with oncogenic co-regulatory proteins (CoRs). However, molecular details of isoform-specific PR-CoR interactions remain poorly understood. Using structural mass spectrometry, we investigate the sequential binding mechanism of purified full-length PR and intact CoRs, steroid receptor coactivator 3 (SRC3) and p300, as complexes on target DNA. Our findings reveal selective CoR NR-box binding by PR and unique interaction surfaces between PR and CoRs during complex assembly, providing a structural basis for CoR sequential binding on PR. Antagonist-bound PR showed persistent CoR interactions, challenging the classical model of nuclear receptor activation and repression. Collectively, we offer a peptide-level perspective on the organization of the PR transcriptional complex and infer the mechanisms behind the interactions of these proteins, both in active and inactive conformations.

Published: November 2024

Abstract

Vibration welding is a common industrial technique used to join thermoplastic components. One of its drawbacks is the generation of small particulate debris during welding. Preheating the weld interface is currently the primary technique that minimizes debris formation; however, it incurs a cycle time penalty. This study is the first to examine the effect of vibration welding conditions on the formation of debris using a wide range of unreinforced and glass-fiber-reinforced polypropylene polymers and compounds. The work shows that all materials form small, twisted strand-like debris particles. Generally, brittle grades form more debris than ductile materials. Surprisingly, higher weld pressures decrease the quantity of debris. The volume of debris is not greatly affected by the meltdown suggesting that debris is formed in the initial stage of the welding. The work then focused on the formation of relatively long strands, referred to as fibrils, very early in the process. The shape and texture of the fibrils are very similar to those of the debris particles suggesting that debris is related to the formation and rupture of the fibrils. A mechanism is proposed that explains how fibrils are created during welding and their relation to debris.

Published: November 2024

Abstract

In large-scale multiple-input-multiple-output (mMIMO) networks, effective power control (PC) mechanisms play a pivotal role. Various algorithms, such as the weighted mean square error (WMMSE) algorithm, are utilized to estimate PCs, demanding considerable computational resources. This study examines the performance of PC in mMIMO systems, emphasizing the aggregate spectral efficiency (sum SE) and the cumulative distribution function (CDF) constrained by SE per user equipment (UE). This investigation explores the impact of different factors, including the number of UEs, access points/base stations (APs/BSs), and the implementation of deep neural network (DNN)-based PCs, within both cellular (CL) and cell-free (CF) architectures. Through empirical analysis, the study elucidates the influence of parameter 'g' on the DNN versus WMMSE comparison curve, underscoring the importance of accounting for the quantity of APs/BSs and antennas to attain optimal PC performance.
