Quantum Approximate Optimization Algorithms for Maximum Cut on Low-Girth Graphs
Authors: Li Tongyang , Su Yuexin , Yang Ziyi , Zhang Shengyu 
Published: February 2025

Abstract

Maximum cut (MaxCut) on graphs is a classic NP-hard problem. In quantum computing, Farhi, Gutmann, and Goldstone proposed the Quantum Approximate Optimization Algorithm (QAOA) for solving the MaxCut problem. Its guarantee on cut fraction (the fraction of edges in the output cut over all edges) was mainly studied for high-girth graphs, i.e., graphs with only long cycles. On the other hand, low-girth graphs are ubiquitous in theoretical computer science, including expander graphs being outstanding examples with wide applications in theory and beyond. In this paper, we apply QAOA to MaxCut on a set of expander graphs proposed by Mohanty and O'Donnell known as additive product graphs. Additionally, we apply multi-angle QAOA (ma-QAOA) to better utilize the graph structure of additive product graphs in ansatz design. In theory, we derive an iterative formula to calculate the expected cut fraction of such graphs. This formula also extends to the quantum MaxCut problem. On the other hand, we conduct numerical experiments to compare between best-known classical local algorithms and QAOA with constant depth. Our results demonstrate that QAOA outperforms the best-known classical algorithms by 0.3% to 5.2% on several additive product graphs, while ma-QAOA further enhances this advantage by an additional 0.6% to 2.5%. In particular, we observe cases that ma-QAOA exhibits superiority over best-known classical algorithms but QAOA does not. Furthermore, we extend our experiments to planar graphs such as tiling grid graphs, where QAOA also demonstrates an advantage.
A content analysis of how biology textbook tasks address system thinking skills in the context of the carbon cycle
Authors: Düsing Katharina 
Published: February 2025

Abstract

Understanding the global cycling of carbon is critical to participate in the current public discussion on climate change in an informed manner. Fostering system thinking is key to reach this goal. Of the various influences on students' development of system thinking in relation to the carbon cycle, the present study focuses on the influence of textbooks – both their explanatory text and the activities they provide for students. Research-based information pertaining to ways students work on acquiring system thinking skills when solving textbook tasks on the carbon cycle is scarce. Therefore, this study investigates two research questions: (1) Which system thinking skills are addressed in German biology textbook tasks on the carbon cycle? and (2) Which entities and activities from different levels of biological organization do students deal with when working on the tasks? The second research question relates to the argument that the multi-level character of the carbon cycle causes particular learning difficulties for students. Following a qualitative content analysis, two coding schemes are developed and applied. The main results: the system thinking skills “identifying system organization” and “analyzing system behavior” are more frequently addressed than “system modeling”. The selection of entities and activities of the carbon cycle in the tasks depicts a variety of individual aspects but often does not allow a continuous tracing of dynamics in the carbon cycle along carbon flows. We suggest a greater emphasis on systems modeling in carbon cycle tasks and that the selection of entities and activities should support knowledge integration.

Abstract

Flash floods in the Haor regions of Bangladesh frequently destroy Boro rice crops at maturity or near maturity, leading to farmers' reluctance to invest adequately in cultivation, resulting in poor crop management and reduced productivity. However, adopting improved agricultural practices, such as selecting suitable rice varieties and optimizing planting schedules, can significantly enhance Boro rice yields and mitigate the impact of flash floods. An on-farm experiment was conducted from December 2021 to May 2022 in the flood-prone region of Sunamganj, Bangladesh, using a three-factor split-split plot design with three replications. The study evaluated the effects of sowing dates (15 December and 30 December), rice varieties (BRRI dhan28, a short-duration variety; and BRRI dhan92, a long-duration variety), and management practices (poor, moderate, and good) on Boro rice production. Results indicated that good management practices led to significant yield increases of 22.2% and 55%, along with gross margin improvements of 23.8% and 64.5%, compared to moderate and poor management. The long-duration variety (BRRI dhan92) performed best with early planting, while the short-duration variety (BRRI dhan28) excelled with later planting. Despite the high yield potential of BRRI dhan92, early planting posed a higher risk of flash flood damage at maturity. These findings highlight the importance of strategic cultivar selection, optimized planting times, and improved management practices to maximize Boro rice productivity in flood-prone regions and reduce the risk of crop loss due to flash floods.

Authors: Dongre Amol , Sood Karan , Dongare Trupti , Arora Brijesh 
Published: February 2025

Abstract

Background
Hodgkin’s Lymphoma (HL) is one of the most curable malignancies of childhood, with chemotherapy alone or in combination with radiotherapy (RT) being the preferred treatment modality, albeit associated with significant acute and late toxicities. Therefore, this retrospective study aims to comprehend clinical-biological differences from the west, analyse local prognostic factors, and evaluate outcomes and toxicity with current therapy.
Methods
This retrospective study included 355 treatment-naive patients with classical HL. All patients received 4–8 cycles of upfront ABVD-based chemotherapy followed by involved field radiotherapy (IFRT) to the bulky/residual sites. Relapsed patients received one of the commonly used salvage regimens (GDP, ICE, or MINE). Analyses were conducted for interim response assessment and end-of-treatment response.
Results
Out of the 355 patients evaluated, 167 presented with advanced-HL (Stage IIBX, III & IV), and 15 of these 167 were ineligible for the final analysis due to various reasons. The median age was 9.7 years, and the male-to-female ratio was 5.9:1. The primary histologic subtype was mixed cellularity. The majority (73%) had stage III disease, with 80 out of 152 (53%) presenting 'B' symptoms and 69 out of 152 (45%) having bulky disease. Extranodal involvement was observed in 26% of patients. The first-line treatment regimen was ABVD for all patients, with IFRT in 68 (44.7%) cases. At the end of therapy, 83% of patients achieved complete remission (CR), while 32 (21%) progressed or relapsed. The median follow-up was 37 months, and the overall survival (OS) and event-free survival (EFS) rates were 83.6% and 78% at three years, respectively. These survival rates were lower than those reported in studies from the west. The CHIPS score was a prognostic factor that evaluated four of the mentioned factors (Stage IV, bulky mediastinal disease, serum albumin, and fever). The event-free survival rate was 83% for patients with a CHIPS score of 0 or 1, 70% for those with a CHIPS score of 2, and 61% for those with a CHIPS score of 3 or 4.
Conclusion
The CHIPS score can predict the outcome of children with advanced HL treated with ABVD-based therapy but requires prospective validation.
Predicting current and future distributions of wild medicinal shrubs Ephedra alata Decne (Ephedraceae) under climate change in Tunisia
Authors: Wibowo Andrio 
Published: February 2025

Abstract

Ephedra alata is a common wild medicinal plant species in Tunisia. The ongoing utilization of E. alata for medicinal applications and uses is threatened by the changing climate, and this can lead to the potential decline of E. alata's geographic distribution range in Tunisia. In this study, we use species distribution modeling to estimate both the current and future potential distribution of E. alata, providing a basis for E. alata suitable habitats across Tunisia. Herein, the future climate model was based on two future representative concentration pathways representing optimistic scenarios (RCP 2.6) and pessimistic scenarios (RCP 8.5) in the years 2070. The mean temperature of the coldest quarter, the temperature seasonality, and the precipitation of the driest quarter, known as bioclimatic variables, contribute significantly to the E. alata distributions. Under an optimistic scenario, the distribution ranges of E. alata remained stable. On the contrary, under a pessimistic scenario in 2070, the distribution ranges of E. alata across governorates in Tunisia will decline, with ranges of 44.17–95.35%, or climate change will cause the disapearance of E. alata. In the future, E. alata will only be available in the western region, where it was previously common in the central and eastern regions.

Published: February 2025

Dazomet is a fumigant commonly used to control soil seedbanks and plant tissues of weed species in highly infested turfgrass areas. This fumigant reacts with water in the soil when in the presence of oxygen and releases methyl isothiocyanate (MITC) gas that kills seeds and plant tissues within the soil. Previous studies have reported varying levels of weed control by dazomet. As MITC is highly water soluble, mobile in soil, and volatile, inconsistencies in dazomet efficacy may be related to post-application practices of tilling, rolling, irrigation, and tarping. Therefore, the objective of this study was to analyze the effect of two practices commonly performed following dazomet application: tarp treatment (tilling, rolling, irrigation, and tarping), and water-seal treatment (post-irrigation at 0, 1, 2, and 3 days after application) on MITC concentration, distribution, and persistence in sandy soil. Field studies were conducted at Sandhills Research Station in Jackson Springs, NC, USA, in 2022 and 2023. MITC concentration and persistence varied between treatments and years. In 2022, MITC concentrations were notably higher in the tarp treatment compared with the water-seal treatment, whereas in 2023, the difference between treatments was less pronounced and more soil depth– and sample timing–dependent. Both treatments presented longer persistence, up to 168 hours after application (HAA), in 2023 compared with 120 HAA in 2022. In addition, MITC was highly concentrated in the top 15 cm of the soil and was detected as deep as 31 cm down from the soil surface in both treatments across both years.

Tea (Camellia sinensis)
Authors: Kaur Prabhjot , Deswal Geeta , Chopra Bhawna , Kriplani Priyanka , Grewal Ajmer Singh , Dhingra Ashwani K. 
Published: February 2025

Background:
Camellia sinensis has an extensive variety of pharmacological properties,
including neuroprotection, photo-aging resistance, stress resistance, antioxidant, anti-tumour, hypoglycemic, antibacterial, and antiviral effects tracing a good potential in addressing illness and
preventing disease. Challenges with conventional dosage forms include patient incompatibility,
improper dosing, the inclusion of microplastics, etc.

Objective:
The present work aims to deliver a novel formulation devoid of microplastics and with
improved consumer compliance

Methods:
Wet granulation was used to formulate 500 mg Camellia sinensis effervescent tablets,
with improved effervescent time and rapid release. Citric acid and sodium bicarbonate's impacts on
disintegration time and pH were examined using a factorial design. Pre-compression variables were
assessed for the granule mixture. Post-compression criteria were employed to assess effervescent
tablets. The optimum formulation was selected using a central composite response surface and assessment criteria

Results:
The physicochemical characteristics of the developed formulations were significantly influenced by the independent factors. Low concentrations of sodium bicarbonate have positive impact on pH whereas high concentrations of sodium bicarbonate as well as citric acid enhance disintegration time. The design outcomes showed that the optimized effervescent tablets (F10) prepared
with 697.5 mg and 448.38 mg of citric acid and sodium bicarbonate respectively had good physicochemical properties.

Conclusion:
In compliance with present quality standards, factorial design was efficiently utilized
for the development of Camellia sinensis effervescent tablets. It was concluded that green tea effervescent tablet (F10) would function as a substitute for conventional green tea powder along with
green tea bags as a means of administration.
The Psychosocial Account of the Social Added Value of Nonprofit and Voluntary Organizations: A Participatory Study
Authors: Tommasi Francesco , Meneghini Anna Maria , Pistoni Carlo , de Cordova Federica 
Published: February 2025

Background
The psychosocial perspective of the Social Added Value (SAV) is a valuable account of the social impact of Nonprofit and Voluntary Organizations (NPVOs). This is because it recognizes the economic impacts of NPVOs. However, the existing top-down operationalization of SAV still needs the integration of a bottom-up perspective (i.e., NPVOs’ members' perspective).

Objectives
Following a participatory research approach, the study seeks to complement the existing psychosocial perspective with bottom-up perspectives on SAV.

Methods
The study uses concept mapping, a participatory stakeholder-driven process, to generate a framework of SAV on a sample of NPVO managers (N = 105).

Results
The results of the participatory study reveal that the elements characterizing NPVOs’ SAV act in a circuit of benefits comprising the contextualization of the individual in the community and contributing to the lives of people in and around the community. This bottom-up operationalization of NPVOs’ SAV comprises six main benefits, namely (a) state and territory, (b) care and awareness, (c) create and valorize relationships, (d) community and social promotion, (e) well-being and (f) self-determination, and local activation.

Conclusion
The findings of the study provide indications to complement the psychosocial perspective of SAV and its implications for theory and practice. Notably, these findings appear to reflect the ecological perspective of community psychology. As such, they offer a starting point for tailoring interventions to support and promote communities and NPVOs.

ABSTRACT

Objectives
To evaluate the effects of rs1799750 1G/2G polymorphism of the MMP1 gene and rs1800470 T/C polymorphism of the TGF-ß1 gene on temporomandibular disk displacement and vertical facial development.

Materials and Methods
Sixty-six individuals were examined radiographically prior to evaluation of the signs/symptoms of temporomandibular disorders according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Class II, hyperdivergent individuals with TMD (+) were assigned to Group 1, and individuals with TMD (−) were included in Group 2; while Class I, normodivergent individuals with TMD (−) were included in Group 3. For genetic analysis, oral mucosa swab samples were collected, and genotype analysis was performed.

Results
The incidence of 2G alleles in Group 2 (72.7%) was significantly higher than the other groups (P &lt; .05). ANB angle and mean Wits of the 1G/1G genotype of the MMP1 gene were significantly lower than 1G/2G and 2G/2G. Mean Go-Gn of the 1G/1G genotype was significantly higher than that of 1G/2G. The mean SNB of the TGF-β1 TT genotype was significantly higher than TC. The mean Co-Gn of TT was significantly higher than CC.

Conclusions
A relationship was found between the 2G allele of rs1799750 1G/2G polymorphisms of the MMP1 gene and the risk of individuals developing disk displacement. Also, it was found that TGF-ß1 gene rs1800470 29 T/C polymorphisms had a detrimental effect on mandibular development.

Published: February 2025

Differences in views regarding the originality of the Qur’an between classical and contemporary orientalists are increasingly problematic. Library research data collection techniques. The collected data are classified and analyzed using Emmanuel Kant’s epistimological theory. The data sources used consisted of primary sources obtained from several orientalists and secondary sources obtained from several previous studies. The result of this studi, first, teh differences in the view of the orientalists were influenced by three things, namely the main source, methodology, and the validity of the truth used to measure originality of the Qur’an. Second, classical orientalists in their studies tend to be theological in nature, while contemporary orientalists tend to be sociological, anthropological, and do not involve the realm of theology, so the results are more objective. Thrid, the similarity of some contents of the Qur’an is considered normal because the Qur’an is affirmative and complements existing books.
