تجليات الواقع الاجتماعي والسياسي في الخطاب السينمائي الفلسطيني: فيلم "عيد ميلاد ليلى" نموذجاً
Authors: الراعي غادة حمدي
Published: July 2023

السينما من أهم الأدوات الثقافية التي يستخدمها صناع الأفلام الفلسطينيون لتوثيق انتهاكات قوات الاحتلال الإسرائيلي ضد شعبهم ورصد التغيرات الاجتماعية والسياسية في الأراضي الفلسطينية المحتلة وتسليط الضوء على المشاكل التي تواجه الناس أثناء ممارستهم للحياة اليومية. وفي ظل غياب الوحدة الوطنية الفلسطينية وتشديد الحصار الإسرائيلي المفروض على قطاع غزة والضفة الغربية، ظهرت أفلام تنتقد الوضع الفلسطيني الداخلي. تتناول هذه الدراسة فيلم "عيد ميلاد ليلى" للمخرج رشيد مشهراوي لتناقش تجليات الواقع الاجتماعي والسياسي في الخطاب السينمائي الفلسطيني. اعتمدت الدراسة على المنهج الوصفي، وفي إطاره تم تحليل هذا الفيلم الذي رَكَّز على تراجع منظومة القيم الاجتماعية في فلسطين. وقد توصلت الدراسة إلى أن فيلم "عيد ميلاد ليلى" كسر الصورة النمطية التي تقدم المجتمع الفلسطيني على أنه مجتمع ثوري، متماسك، وقوي، وأبرز تداعيات الانقسام الداخلي والحصار الإسرائيلي على الأوضاع الاجتماعية والاقتصادية، وسلط الضوء على الفوضى التي تسود المجتمع. وقد قدم الفيلم تفاصيل دقيقة عن الواقع اليومي الذي يعيشه المواطن الفلسطيني في الضفة الغربية في قالب فني بسيط وسلس يبرهن على جمالية لغة السينما الفلسطينية الجديدة وجودة أساليبها في معالجة مشاكل المواطنين والتعبير عن معاناتهم، بعيداً عن الشعارات الوطنية الخطابية.

Published: July 2023

Free energy perturbation (FEP) remains an indispensable method for computationally assaying prospective compounds in advance of synthesis. But before FEP can be deployed prospectively, it must demonstrate retrospective recapitulation of known experimental data where the subtle details of the atomic ligand-receptor model are consequential. An open question is whether AlphaFold models can serve as useful initial models for FEP in the regime where there exists a congeneric series of known chemical matter but where no experimental structures are available either of the target or of close homologues. As AlphaFold structures are provided without a ligand bound, we employ induced-fit docking to refine the AlphaFold models in the presence of one or more congeneric ligands. In this work, we first validate the performance of our latest induced-fit docking technology, IFD-MD on a retrospective set of public experimental GPCR structures with 95% of crossdocks produc-ing a pose with a ligand RMSD ≤ 2.5 Å in the top 2 predictions. We then apply IFD-MD and FEP on AlphaFold models of the somatostatin receptor family of GPCRs. We use AlphaFold models produced prior to the availability of any experi-mental structure from within this family. We arrive at FEP-validated models for SSTR2, SSTR4, and SSTR5, with RMSE around 1 kcal/mol and explore the challenges of model validation under scenarios of limited ligand-data, ample ligand data, and categorical data.
Functionalizing DNA Origami by Triplex-Directed Site-Specific Photo- Crosslinking

Published: July 2023

Here we present a universal method to introduce functionality and improve the structural integrity of DNA origami in a one-pot reaction. Our strategy involves adding nucleotide sequences to adjacent staple strands so that, upon origami assembly, the add-on sequences form short hairpin duplexes targetable by psoralen-labelled triplex-forming oligonucleotides (pso-TFOs) bearing other functionality. Subsequent irradiation with UVA light generates psoralen adducts with one or both hairpin staples leading to site-specific attachment of the pso-TFO to the origami with >80% efficiency. Bis-adduct formation between strands in proximal hairpins further tethers the TFO to the structure and generates ‘super-staples’ that improve the structural integrity of the complex. We also show that crosslinking reduces the sensitivity of the functionalized origami to thermal denaturation and disassembly by T7 RNA polymerase. Our strategy is scalable and cost-effective as it works with existing DNA origami structures, does not require scaffold redesign, and can be achieved with just one psoralen- modified oligonucleotide. It is also non-damaging to the origami scaffold, as well as to introduced fluorescent functionalities.
Novel Computational Chemistry Infrastructure for Simulating Astatide in Water: From Basis Sets to Force Fields Using Particle Swarm Optimization
Authors: Espinosa Kennet , Kananenka Alexei , Rusakov Alexander
Published: July 2023

Using the example of astatine, the heaviest naturally occurring halogen whose isotope At-211 has promising medical applications, we propose a new infrastructure for large-scale computational models of heavy elements with strong relativistic effects. In particular, we focus on developing an accurate force field for At– in water based on reliable relativistic DFT calculations. To ensure such calculations’ reliability, we design novel basis sets for relativistic DFT via the polarization-consistent basis set idea’s extension to heavy elements, thus eliminating the basis-set error from DFT calculations. The resulting basis sets enable the well-grounded evaluation of relativistic DFT against “gold-standard” CCSD(T) results. We employ the evolutionary algorithm called particle swarm optimization for the force field and basis set efficient optimization. Accounting for strong relativistic effects, including spin-orbit interaction, via our redesigned infrastructure, we elucidate a noticeable dissimilarity between At– and I– in halide–water force field parameters, radial distribution functions, diffusion coefficients, and hydration energies. This works establishes the framework for the systematic development of polarization-consistent basis sets for relativistic DFT and accurate force fields for molecular dynamics simulations to be used in large-scale models of complex molecular systems with the elements from the bottom of the periodic table, including actinides and even superheavy elements.

Published: July 2023

Indolines, characterized by their diverse biological activities and structural significance, have garnered considerable attention in the realms of natural product synthesis and drug discovery. Concurrently, the incorporation of fluorine atoms into organic molecules has emerged as a powerful strategy to enhance their pharmacological properties. Herein, we report a robust and diastereoselective approach for the synthesis of 2,3-difluorinated indolines through the iodine(I/III)-catalyzed dearomatization of readily available indoles. The protocol operates under mild conditions, displaying excellent functional group tolerance and remarkable diastereoselectivity. By employing this developed protocol, vicinal-difluorinated analogues of indole-containing drugs can be efficiently accessed. Theoretical calculations have shed light on the underlying reaction mechanism, proposing the formation of a β-fluorine-substituted carbocation intermediate. It is postulated that the observed high diastereoselectivity can be attributed to the dipole-dipole interactions facilitated by the C-F bond. Crystallographic analysis has revealed the profound impact of fluorine atom introduction on the conformational preferences of the indoline core. Given the unique structural characteristics and pharmacological significance of 2,3-difluorinated indolines, we anticipate their widespread application in medicinal chemistry and drug discovery endeavors.

To learn about the strain/stress distribution in a material is essential to achieving its mechanical stability and proper functionality. Conventional techniques such as universal testing machines only applies to static samples with standardized geometry in laboratory environment. Soft mechanical sensors based on stretchable conductors, carbon-filled composites or conductive gels possess better adaptability, but still face challenges from complicated fabrication process, dependence on extra readout device and limited strain/stress mapping ability. Inspired by the camouflage mechanism of cuttlefish and chameleons, here we developed an innovative strain/stress responsive hydrogel containing ‘mechano-iridophores’. Force induced reversible phase separation manipulated the dynamic generation of mechano-iridophores, serving as indicators of local deformation. Patch-shaped mechanical sensors made from the responsive hydrogel featured fast response time (<0.4 s), high spatial resolution (~100 μm) and wide dynamic ranges (e.g. 10%-150% strain). The intrinsic adhesiveness and self-healing capability of sensing patches also ensured their excellent applicability and robustness. Importantly, the optical readout allowed strain/stress distributions to be directly identified by naked eyes or smartphone apps, which had not yet been achieved before. The great advantages above are ideal for developing the next-generation mechanical sensors towards material studies, damage diagnosis, risk prediction and smart devices.
Predicting the Solubility of Gases, Vapors, and Supercritical Fluids in Amorphous Polymers from Electron Density using Convolutional Neural Networks
Authors: Gromov Oleg
Published: July 2023

A twin convolutional neural network is proposed to predict the pressure and temperature-dependent sorption of gases, vapors, and supercritical fluids in amorphous polymers based solely on spatial electron density distribution. Quantum chemical data as 3D tensors (3D images) is derived from DFT calculations. A dataset of almost 15000 experimentally measured uptakes (0.01-50 wt%) of 79 gases in 102 different polymers under pressures from 1E-3 – 7E+2 bar range and temperatures from 233-508 K range is collected from over 250 literature sources. The dataset includes measurements on almost 500 solvent-polymer systems spanning from typical low-pressure sorption in membrane glassy polymers to high-pressure solubility of supercritical fluids in molten polymers. Irreducible mean absolute percentage error (MAPE) is approximately estimated to be ~20%. The sources of inherent data variability are briefly discussed. In 150 epochs, the model achieved 31% MAPE on a test set of 1600 experimental measurements concerning 22 polymers previously unseen by the model.
On the thermodynamic stability of polycations
Authors: Tikhonov Denis S. , Lee Jason W.L. , Schnell Melanie
Published: July 2023

We present a simple approximation to estimate the largest charge that a given molecule can hold until fragmentation into smaller charged species becomes more energetically favorable. This approximation solely relies on the ionization potentials, electron affinities of the parent and fragment species, and also on the neutral parent's dissociation energy. By parametrizing these quantities, it is possible to obtain analytical phase diagrams of polycationic stability. We demonstrate the applicability of this approach by discussing maximal charge dependence on the size of the molecular system. A numerical demonstration for linear polyenes, monocyclic annulenes, and helium clusters is provided.

In transitional countries with arid climates, water stress is rising as the demand for water rises with population, economic growth, and intensive development of agriculture and energy and change in climate environment. In this regard, transitional nations plan in national programmes and policies alternative energy sources, sustainable food development, and circular water resource usage. However, these nations frequently approach current water, energy, and food planning without taking interactions of these resources and their impact on each other into account. This paper intends to demonstrate the significance of the water, energy, and food nexus approach for Central Asian countries in transition. Kazakhstan is used as an example of a resource-rich, transitional economy in Central Asia. Kazakhstan has set a goal of reaching a 50% share of renewable and alternative energy sources in electricity generation by the year 2050 to reduce water and energy poverty, improve water and energy efficiency, achieve carbon neutrality, and rank among the top 30 developed nations. To meet the water and renewable energy goal, bioenergy plantation is anticipated to develop between 2030 and 2050. The findings of paper show that total withdrawals for bioenergy increase from the reported data of 15503.68 m3 in 2020 to 32182.16 m3 in 2050 under a bioenergy-intensive scenario. The average total increase, or 75.5%, would be 16678.48 m3. As such, policymakers and stakeholders in Central Asian region and Kazakhstan needs to carefully design its national energy goals given its future increase of water withdrawals, and shortage environment.

Authors: Nicole A Bailey , Khalifah A Aldawsari , Carlo M Zeidenweber , Danyal M Khan*
Published: July 2023

Introduction: Congenital heart disease is a leading cause of neonatal mortality linked to birth defects. Despite the widespread availability of prenatal screenings, detection rates remain low. Accurate early detection of these lesions is pivotal to reducing neonatal morbidity and mortality. Methods: In this case, we present a neonate who experienced sudden cardiac death due to a rare, undiagnosed congenital cardiac anomaly - the bilateral absence of coronary artery ostium.  Discussion: This case highlights the importance of prenatal detection of congenital cardiac anomalies. While fetal echocardiography is frequently utilized, it only identifies CHD in 36-50% of cases. This is attributed to inadequate imaging procedures, varied operator skills, and regional discrepancies. Early detection of severe CHD is essential for specialized treatment, thereby mitigating neonatal health risks and improving survival rates. Conclusion: Prenatal detection of CHD, especially coronary anomalies, continues to pose significant challenges. There is a pressing need to establish and enforce standardized protocols for fetal echocardiography aimed at these anomalies. To enhance care and improve outcomes, a joint effort between academic institutions and community centers is encouraged. Learning Objectives: • Congenital coronary artery anomalies are a significant cause of sudden cardiac death in children. • The absence of a coronary artery ostium is known to be associated with other congenital heart diseases, particularly pulmonary atresia with an intact ventricular septum. However, isolated coronary disease has also been reported in this case. • Prenatal echocardiography is a valuable tool for diagnosing congenital heart disease. However, certain limitations may be encountered when diagnosing coronary artery anomalies.

One of the key benefits of understanding regional electricity consumption and its response to policy changes is enhancing the decision-making process. In Saudi Arabia, energy policies are set at the national level, and assessing their impacts at the regional level provides valuable insights for assessing the impact of previous and future policies. The regions of Saudi Arabia have unique social and economic characteristics (Mikayilov et al. 2020b) and are expected to react differently to changing policies.

Published: July 2023

Çalışmada kullanılan teorik model cari işlemler dengesi analizlerinde temel referans olarak kabul gören Obstfeld and Rogoff (1994, 1996)’un geliştirdiği zamanlara arası yaklaşıma (intertemporal approach) dayanmaktadır. Bu zamanlar arası yaklaşıma göre cari işlemler dengesi, ileriye dönük dinamik tasarruf ve yatırım kararlarının bir sonucudur. Bu çalışmada, Türkiye’de tasarruf ve yatırım dengesinin cari açık üzerindeki etkisi, 1975-2019 dönemi için çeşitli eşbütünleşme yöntemleri kullanılarak analiz edilmiştir. Eşbütünleşme testlerinde karşılaştırma sağlamak için Engle-Granger ve Johansen eşbütünleşme testleri kullanılmıştır. Yapılan analiz sonucunda cari açığın Gayri Safi Yurtiçi Hasıla’ya oranı ile yatırımların Gayri Safi Yurtiçi Hasıla’ya oranı ve tasarrufların Gayri Safi Yurtiçi Hasıla’ya oranı arasında uzun dönemli bir ilişki bulunmuştur. Buna ek olarak eşbütünleşme tahmincileri olan FMOLS, DOLS ve CCR kullanılmış, elde edilen bulgulara bakıldığında tasarruf yatırım dengesi ile cari açık arasında negatif bir ilişki olduğu belirlemiştir.

Egg quality maintaining with high egg production is actual problem. This research task has been to analyze quail egg morphologic and biochemical composition in Omskaya quail breed in groups that are divergent in egg production (±1.5 ÷2σ from average). Eggs of quails with high egg production intensity had greater egg shell mass (by 0.19 g, P<0.001) and less white mass (by 0.47 g, P<0.05). Outer layers proportion has changed with egg production increasing. Protein content in quail egg white and yolk have been 10.64 and 16.71% in quails with high egg production that is less than in quails with low egg production by 0.1 and 0.23% respectively.
Messiha and Stokes (2023). A Qualitative Study on the Contemporary Perspectives and Experiences of Co-residence during Covid-19 among ‘Boomeranging’ Young Adults and their Mothers in England. (Preprint)
Authors: Messiha Katrina , Stokes Gillian
Published: July 2023

Abstract:

The ‘Boomerang Effect’ (BE) is a contemporary phenomenon in England and wider Europe, referencing young adults who move out of their parents' home to live independently but eventually return to live with their parents again. Despite concerns about residential independence and the intensification of BE due to the Covid-19 pandemic, there is limited qualitative data investigating it. This qualitative study utilises diary methods to elicit the perspectives and experiences from six mother-young adult child dyads in England for 21 days to enable holistic and dynamic insights on the day-to-day exposures to the BE phenomenon. Findings resulted in several salient themes: (1) prime concerns shaping living arrangements, (2) framing of [participant] role, (3) conceptualisation of [participant] identity, (4) nature of family relations, (5) depiction of independence, and (6) perceived situational input of Government. This work underscores the interdependent and complex relationship between structure and agency manifest in the BE context.

-

This preprint contributes valuable knowledge to the existing literature on the Boomerang Effect and offers nuanced insights into the experiences of both young adults and their mothers as they navigate the challenges and opportunities presented by this contemporary trend during the Covid-19 pandemic. The implications of these findings may inform policies and support systems to better address the needs of young adults and families in the changing landscape of living arrangements.

In recent years, despite the strict "zero tolerance" crackdown on the financial fraud and violation behavior of listed companies, the cases of financial fraud, revenue and profit overstatement, and suspected fraud have continued to be exposed. This study first established a financial fraud index system and used the XGBoost algorithm to construct a prediction model for financial fraud and violations of listed companies. The indicators were selected and input into the model. A dataset was obtained for experiments. The XGBoost algorithm was compared with two other algorithms. The receiver operator characteristic (ROC) curves showed that the XGBoost algorithm had the best prediction performance among the three algorithms. It was found that the precision of the XGBoost algorithm was 93.17%, the recall rate was 92.23%, the value was 0.9270, and the area under the curve was 0.90, indicating a better performance than the prediction models based on the Gradient Boosted Decision Tree (GBDT) algorithm and the Logistics algorithm. Considering the data of various evaluation indicators, it is found that the predictive effect of the financial fraud and violation prediction model built by the XGBoost algorithm is the best.
Enthusiastic and Grounded, Avoidant and Cautious: Understanding Public Receptivity to Data and Visualizations
Authors: He Helen Ai , Walny Jagoda , Thoma Sonja , Carpendale Sheelagh , Willett Wesley
Published: July 2023

Despite an abundance of open data initiatives aimed to inform and empower “general” audiences, we still know little about the ways people outside of traditional data analysis communities experience and engage with public data and visualizations. To investigate this gap, we present results from an in-depth qualitative interview study with 19 participants from diverse ethnic, occupational, and demographic backgrounds. Our findings characterize a set of lived experiences with open data and visualizations in the domain of energy consumption, production, and transmission. This work exposes information receptivity — an individual’s transient state of willingness or openness to receive information — as a blind spot for the data visualization community, complementary to but distinct from previous notions of data visualization literacy and engagement. We observed four clusters of receptivity responses to data- and visualization-based rhetoric: Information-Avoidant, Data-Cautious, Data-Enthusiastic, and Domain-Grounded. Based on our findings, we highlight research opportunities for the visualization community. This exploratory work identifies the existence of diverse receptivity responses, highlighting the need to consider audiences with varying levels of openness to new information. Our findings also suggest new approaches for improving the accessibility and inclusivity of open data and visualization initiatives targeted at broad audiences.
