description: We have used numerical modeling and a semi-analytical calculation method to find the low frequency value S_{I}(0) of the spectral density of fluctuations of current through 1D arrays of small tunnel junctions, using the ``orthodox theory'' of single-electron tunneling. In all three array types studied, at low temperature (kT << eV), increasing current induces a crossover from the Schottky value S_{I}(0)=2e to the ``reduced Schottky value'' S_{I}(0)=2e/N (where N is the array length) at some crossover current I_{c}. In uniform arrays over a ground plane, I_{c} is proportional to exp(-λN), where 1/λis the single-electron soliton length. In arrays without a ground plane, I_{c} decreases slowly with both N and λ. Finally, we have calculated the statistics of I_{c} for ensembles of arrays with random background charges. The standard deviation of I_{c} from the ensemble average is quite large, typically between 0.5 and 0.7 of , while the dependence of on N or λis so weak that it is hidden within the random fluctuations of the crossover current.

description: Language plays an important role in modern society. Nowadays verbal communication is necessary in almost every social and vocational environment. Hence, impairment of language has serious effects on an individual´s life. Language impairments, such as aphasia, are very often the result of a stroke. Despite the relevance of aphasia in society, there is only a small amount of data concerning the long term effects of different types of aphasia and their impact on social and vocational rehabilitation after stroke. Therefore the purpose of this study was to investigate the long term effects of aphasia after the occurrence of a stroke in relation to the social and vocational rehabilitation of such patients. The secondary goal was the investigation of prognostic factors indicative of social and vocational reintegration. 127 stroke patients with aphasia (target group) and 80 patients without aphasia (control group) were compared at time of admission to neurological rehabilitation and 12 months after discharge. An aphasia-test as well as rating scales to describe motor, cognitive and psychosocial status were administered. Findings indicate that aphasia after stroke has negative effect on vocational outcome. Language comprehension, which was a subscore of the administered aphasia-test, seemed to be a good prognostic factor for vocational outcome. Furthermore, there was no statistical difference between the groups with regard to social reintegration.

description: We report on the optical properties of undoped single crystal LaMnO_3, the parent compound of the colossal magneto-resistive manganites. Near-Normal incidence reflectance measurements are reported in the frequency range of 20-50,000 cm-1 and in the temperature range 10-300 K. The optical conductivity, s_1(w), is derived by performing a Kramers-Kronig analysis of the reflectance data. The far-infrared spectrum of s_1(w) displays the infrared active optical phonons. We observe a shift of several of the phonon to high frequencies as the temperature is lowered through the Neel temperature of the sample (T_N = 137 K). The high-frequency s_1(w) is characterized by the onset of absorption near 1.5 eV. This energy has been identified as the threshold for optical transitions across the Jahn-Teller split e_g levels. The spectral weight of this feature increases in the low-temperature state. This implies a transfer of spectral weight from the UV to the visible associated with the paramagnetic to antiferromagnetic state. We discuss the results in terms of the double exchange processes that affect the optical processes in this magnetic material.

Toutefois, bien que ce modèle de coordination de réseaux complexes se soit doté de capacités de résilience et de configurations adaptatives quant au pilotage des SC en temps de crises, il se heurte à des mécanismes sous-jacents qui influencent son développement. Pour recenser les barrières auxquels le 4PL fait face, nous avons engagé un double appareillage méthodologique qui a révélé, à travers les représentations sociales des décideurs, un ancrage de pratiques réelles et complexes de ce mode de prestation. L’analyse de contenu thématique de discours par le biais de l’analyse automatique sous IRaMuTeQ (interface de r pour les analyses multidimensionnelles de textes et de questionnaires) consolidée par le codage manuel des données selon la méthode de Gioia, ont structuré les barrières au développement des 4PL en trois éléments interdépendants à savoir : un problème de la demande, un problème de neutralité et l’étendu et complexité de la prestation 4PL.

description: Eukaryotic genomes contain thousands of genes organized into complex and interconnected genetic interaction networks. Most of our understanding of how genetic variation affects these networks comes from quantitative-trait loci mapping and from the systematic analysis of double deletion (or knockdown) mutants, primarily in the yeast Saccharomyces cerevisiae. Evolve and re-sequence experiments are an alternative approach for identifying novel functional variants and genetic interactions, particularly between non-loss of function mutations. These experiments leverage natural selection to obtain genotypes with functionally important variants and positive genetic interactions. However, no systematic methods for detecting genetic interactions in these data are yet available. Here, we introduce a computational method based on the idea that variants in genes that interact will co-occur in evolved genotypes more often than expected by chance. We apply this method to a previously published yeast experimental evolution dataset. We find that genetic targets of selection are distributed non-uniformly among evolved genotypes, indicating that genetic interactions had a significant effect on evolutionary trajectories. We identify individual gene pairs with a statistically significant genetic interaction score. The strongest interaction is between genes TRK1 and PHO84, genes that have not been reported to interact in previous systematic studies. Our work demonstrates that leveraging parallelism in experimental evolution is useful for identifying genetic interactions that have escaped detection by other methods.This article is part of the theme issue ‘Convergent evolution in the genomics era: new insights and directions’.

description: Pressure traverse in multiphase flow differs from single phase flow due to the differential flow rates of the different phases. Correlations developed to predict multiphase flow pressure traverse are mostly for vertical wells but Beggs and Brill model is one of the few models that is used for inclined pipes. The work seeks to show the improvement in the modification of the model. This project is based on studies carried out on multiphase fluid flow in pipes of any inclination using the Beggs and Brill flow model as the focus. Two cases were considered, the liquid holdup correction and Gas Liquid Ratio (GLR) variations in which the Beggs and Brill and Beggs and Brill Traverse models were compared. Due to the empirical nature of the Beggs and Brill model, pressure gradient predictions are far from accurate when compared with measured data in the field. This project seeks to reduce the error margin between predicted pressure gradient values and measured data. It was observed that for the same reservoir, fluid, and pipe properties, the Beggs and Brill Traverse Model is a better prediction tool than the Beggs and Brill model. Prediction errors were seen to increase with increase in length for GLR above 400 scf/stb while they were more accurate for pipes between 12,000 and 17,000 ft and pressures between 3,000 and 4,500 psi. However, the Beggs and Brill Traverse Model, is limited by the choice of correlations used in the computation of fluid properties. It is necessary to predict pressure drop in vertical multiphase flow in order to effectively design tubing and optimum production strategies.

description: Perfluoroalkyl compounds (PFCs) have attracted massive attention in recent years for their endocrine-disrupting potential. This review summarizes the underlying evidence on the primary fate and in vitro/vivo toxic effects of PFCs and their interactions and relationships with thyroid dysfunction and cancer induction in exposed groups, including the general population, occupationally exposed groups, highly exposed individuals, and prone subjects (pregnant women and neonates). The potential endocrine-disrupting mechanism of PFCs may include multiple processes of thyroid malfunction or hormonal imbalance. The increased level of thyroid stimulating hormone (TSH) was observed as the most consistent outcome of PFC exposure among generally exposed populations. Specifically, the levels of perfluorooctane sulfonate (PFOS) and TSH were significantly correlated among pregnant women. In some instances, the maternal PFC level was negatively correlated with the neonatal thyroxine (T4) level in serum. The PFCs and thyroid malfunction or thyroid hormone (TH) levels also revealed a potential association among the population under high-level environmental exposure, albeit not always following a strict exposure-response relationship. Moreover, occupational exposure to perfluorooctanoic acid (PFOA) showed a probable link with TH (excluding TSH) alterations in serum. Importantly, no concrete and statistically significant evidence highlighted the risk of thyroid cancer in humans exposed to PFCs. HighlightsThe first robust review describing the effects of PFCs on thyroid dysfunctions.PFC exposure induces sex- and age-specific responses in the human thyroid system.Serum PFOS exposure is positively correlated with TSH in pregnant women.Maternal serum PFC levels are negatively correlated with the neonate’s T4 levels.No statistical evidence supported a concrete association between PFCs and thyroid cancer.

description: The radiative evolution of the relative orientations of the spin and orbital angular momentum vectors ${\bf S}_{\bf 1}, {\bf S}_{\bf 2}$ and ${\bf L}$, characterizing a binary system on eccentric orbit is studied up to the second post-Newtonian order. As an intermediate result, all Burke-Thorne type instantaneous radiative changes in the spins are shown to average out over a radial period. It is proved that spin-orbit and spin-spin terms contribute to the radiative angular evolution equations, while Newtonian, first and second post-Newtonian terms together with the leading order tail terms do not. In complement to the spin-orbit contribution, given earlier, the spin-spin contribution is computed and split into two-body and self-interaction parts. The latter provide the second post-Newtonian order corrections to the 3/2 order Lense-Thirring description.

Writting the equations of motion and the constraints resulting from Hamilton's principle, three classes of exact solutions are presented, for a closed string, encircling the black hole. They all depend on two arbitrary integration functions and two constants. A process of extracting energy is examined for the case of one of the three families of solutions. This is the analog of the Penrose process for the case of a particle.

description: The concept of localization in Fock space is extended to the study of the many particle excitation statistics of interacting electrons in a two dimensional quantum dot. In addition, a finite size scaling hypothesis for Fock space localization, in which the excitation energy replaces the system size, is developed and tested by analyzing the spectral properties of the quantum dot. This scaling hypothesis, modeled after the usual Anderson transition scaling, fits the numerical data obtained for the interacting states in the dot. It therefore attests to the relevance of the Fock space localization scenario to the description of many particle excitation properties.

Single-crystal X-ray diffraction analyses show that Cd-MOF and Zn-MOF possess different two-dimensional (2D) networks and form three-dimensional (3D) frameworks with different stacking modes. Their fluorescence sensing ability for dopamine was studied and it was found that both Cd-MOF and Zn-MOF show fluorescence enhancement in DMF. The turn-on effect may be attributed to the absorbance-caused enhancement (ACE). The results indicate that Cd-MOF and Zn-MOF have potential as fluorescent sensors for dopamine.

description: The kinetics of oxidation catalysis by TAML activators of peroxides [LFeIII(OH2)]− (TAML = tetraamido macrocyclic ligand) in water can be typically quantified by a mechanism comprised of two key steps: catalyst activation to the reactive state with rate constant kI, followed by substrate oxidation with rate constant kII. Usually, kI ≪ kII and the overall catalytic activity is limited by the first step. The second-order rate constant kI can be enhanced by changing structural features in the TAML macrocycle that make the iron site more electrophilic. Chemical interventions beyond changes at the catalyst itself should also be able to change kI. In examining potentially useful interventions, the effect of chloride on kI was explored and an intriguing fact was found. For the NewTAML catalyst, [FeIII{4-NO2C6H3-1,2-(NCOCMe2NSO2)2CHMe}(OH2)]−, increasing chloride concentration reduces the rate constant kI when the pH is below the pKa of the catalyst ([LFeIII(OH2)]− ⇄ [LFeIII(OH)]2− + H+), but increases kI when the pH > pKa. Mechanisms of the observed deceleration/acceleration effects are discussed. A linear dependence between KCl and pKa for iron(III) TAMLs is established: logKCl = 16 ± 2 – (1.6 ± 0.2) × pKa.

description: The search for appropriate structural correlations in molecule-based crystalline salts is of paramount importance to obtain new advanced multifuctional materials with higher performance in nanoscience and nanotechnology. In this article, we focus on the structural features and bonding interactions in the related family of optical- and electroactive molecular salts of anionic mononuclear bis(dithiooxalato)nickel(II), palladium(II), platinum(II), copper(II), copper(III), and zinc(II) complexes with several uni- and divalent, either inorganic or organic countercations. Steric and/or electronic effects of the metal ion and the inorganic or organic countercation determine the molecular structure and conformation of the resulting bis(dithiooxalato)metalate complex anion in the solid state, concerning both the metal coordination environment and the ligand skeleton, twisting and folding along this family of molecular salts.

description: Abstract

This study explores the evolving dynamics in organizational management at the intersection of artificial intelligence (AI), employee empowerment, and leadership dynamics. The infusion of AI into workplaces represents a paradigm shift, challenging traditional roles and redefining work dynamics. To navigate this transformative era, organizations are strategically turning to employee empowerment, aiming to preserve human agency while capitalizing on the benefits of AI. This involves granting individuals greater autonomy and responsibility in response to the evolving nature of work catalyzed by AI technologies. Within this context, transformational leadership emerges as a crucial mediator in the intricate relationship between AI, employee empowerment, and enhanced employee performance. Transformational leaders, renowned for their ability to inspire and motivate, play a pivotal role in fostering a collaborative environment where AI and empowered employees synergize. The confluence of AI and employee empowerment is a pivotal concern in the contemporary business landscape, where AI technologies promise to reshape work processes and extract actionable insights from vast datasets. Simultaneously, employee empowerment strategies aim to boost engagement and performance, emphasizing the complementary nature of human capabilities in the age of AI. Recognizing the significance of these interconnected factors, this study employs a comprehensive literature review approach to shed light on the complex dynamics in modern workplaces. Building on recent research insights, the study provides valuable guidance for organizations, leadership development, and policymakers navigating the evolving landscape of AI adoption and its impact on employee performance.

description: A zinc(II)-porphyrin-cobalt(III) heterodinuclear complex has been designed and synthesized as part of investigating a new approach to selective cancer treatment. Photoinduced electron transfer from a π-π* zinc(II)-porphyrin excited state leads to the release of ligands from the cobalt center. The new, less symmetric meso-functionalized porphyrin, [Zn(L1)] (donor) obtained via reductive amination, was successfully isolated as crystals and characterized by single crystal X-ray crystallography. The cobalt(III) center, with ethane-1,2-diamine (en) ligands (which model the planned nitrogen mustard cytotoxic ligands), is subsequently linked to [Zn(L1)], and the resulting assembly was characterized by NMR spectroscopy.The resulting heterodinuclear complex ([Zn(L1)-Co(en)2]3+) in DMSO-d6 was exposed to ambient light, and ligand release was monitored by 1H NMR spectroscopy. Upon excitation of [Zn(L1)] by visible light, electron transfer to the cobalt(III) center results in reduction to cobalt(II), and release of the ethane-1,2-diamine ligands within 30 min. These findings validate the concept and support further investigations into the synthesis of heterodinuclear complexes with cytotoxic ligands. Our synthetic zinc(II)-porphyrin-cobalt(III) heterodinuclear system shows potential as a model anti-cancer prodrug. It can be used to modify further and explore practical applications in chemotherapy to minimize the side effects of anti-cancer drugs.

description: Figure S5. All isolates containing a TRK1 or a PHO84 mutation. Phylogeny is a ML tree based on 3,835 variable sites. Sequence data was obtained for 2 clones in all populations except C12. The only population in which a pho84 mutation is not accompanied by a mutant trk1, E03, also contains the only synonymous pho84 allele. The only population polymorphic for TRK1, H03, indicates that the PHO84 mutation arose first.

description: Text analytics based on supervised machine learning classifiers has shown great promise in a multitude of domains, but has yet to be applied to Seismology. We test various standard models (Naive Bayes, k-Nearest Neighbors, Support Vector Machines, and Random Forests) on a seismological corpus of 100 articles related to the topic of precursory accelerating seismicity, spanning from 1988 to 2010. This corpus was labelled in Mignan (2011) with the precursor whether explained by critical processes (i.e., cascade triggering) or by other processes (such as signature of main fault loading). We investigate rather the classification process can be automatized to help analyze larger corpora in order to better understand trends in earthquake predictability research. We find that the Naive Bayes model performs best, in agreement with the machine learning literature for the case of small datasets, with cross-validation accuracies of 86% for binary classification. For a refined multiclass classification ('non-critical process' < 'agnostic' < 'critical process assumed' < 'critical process demonstrated'), we obtain up to 78% accuracy. Prediction on a dozen of articles published since 2011 shows however a weak generalization with a F1-score of 60%, only slightly better than a random classifier, which can be explained by a change of authorship and use of different terminologies. Yet, the model shows F1-scores greater than 80% for the two multiclass extremes ('non-critical process' versus 'critical process demonstrated') while it falls to random classifier results (around 25%) for papers labelled 'agnostic' or 'critical process assumed'. Those results are encouraging in view of the small size of the corpus and of the high degree of abstraction of the labelling. Domain knowledge engineering remains essential but can be made transparent by an investigation of Naive Bayes keyword posterior probabilities.

description: An electronic phase separation model provides a natural explanation for a large variety of experimental results in the cuprates, including evidence for both stripes and larger domains, and a termination of the phase separation in the slightly overdoped regime, when the average hole density equals that on the charged stripes. Several models are presented for charged stripes, showing how density waves, superconductivity, and strong correlations compete with quantum size effects (QSEs) in narrow stripes. The energy bands associated with the charged stripes develop in the middle of the Mott gap, and the splitting of these bands can be understood by considering the QSE on a single ladder.

description: Carbon-fibre-reinforced polymer/titanium stack components possess outstanding mechanical properties such as excellent strength-to-weight ratio, high corrosion resistance, stiffness, low density and excellent fatigue properties. These mechanical advantages translate to better fuel efficiency and energy saving. These hybrid materials are not only popular but also a substitute for metals in many structural applications.Recently, a novel machining technique - ultrasonically assisted drilling (UAD) - was introduced to machine hard-to-cut materials, in which vibrations with a low amplitude, low energy and high frequency was superimposed on the drilling tool in the axial direction during the conventional drilling process. This hybrid machining technique brings along several advantages, including multi-fold reduction in forces, required to drill in difficult-to-cut materials such as glass, ceramics, CFRP or hard alloys, hence improving machinability, associated with high-quality surface finish, and meeting standards required for modern materials.Finally, a novel control system is designed and manufactured for UAD machining technique, capable of switching between vibratory parameters for each material constituent in the CFRP/Ti stack was implemented. The development of the control system in UAD resulted in a significant reduction in the average drilling forces, both in the composite and metal phase - 33% – 88%. The developed process appeared to improve drilling in the CFRP/Ti stack, with enhanced surface quality observed, reducing (or, in some cases, eliminating) damages induced during the drilling process in comparison to CD, with a two-to-three-fold reduction in the surface roughness.

description: Social status, a multifaceted construct that encompasses economic, cultural, and symbolic dimensions, plays a crucial role in shaping individual identities and social interactions. The term "social status" describes a person's position in a group or community. By analyzing a group based on the social status of its members, the intra-group dynamics can be better understood.

description: The discovery of unusual negative thermal expansion (NTE) provides the opportunity to control the common but much desired property of thermal expansion, which is valuable not only in scientific interests but also in practical applications. However, most of the available NTE materials are limited to a narrow temperature range, and the NTE effect is generally weakened by means of various modifications. Here, we report an enhanced NTE effect that occurs over a wide temperature range (αV = -5.24 * 10-5 °C^-1, 25-575 ° C), and this NTE effect is accompanied by an abnormal enhanced tetragonality, a large spontaneous polarization, and a G-type antiferromagnetic ordering in the present perovskite-type ferroelectric of (1-x)PbTiO3-xBiCoO3. Specifically, for the composition of 0.5PbTiO3-0.5BiCoO3, an extensive volumetric contraction of ~4.8 % has been observed near the Curie temperature of 700 °C, which represents the highest level in PbTiO3-based ferroelectrics. According to our experimental and theoretical results, the giant NTE originates from a synergistic effect of the ferroelectrostriction and spin-crossover of cobalt on the crystal lattice. The actual NTE mechanism is contrasted with previous functional NTE materials, in which the NTE is simply coupled with one ordering such as electronic, magnetic, or ferroelectric ordering. The present study sheds light on the understanding of NTE mechanisms and it attests that NTE could be simultaneouslycoupled with different orderings, which will pave a new way toward the design of large NTE materials.

title: Pervasive Anxieties about Islam and Muslims in Post-9/11 Hollywood and Bollywood Film Industries
Creators: name: Ftici, Sara
Publisher: name: University of Kent
Year: 2024

description: Popular media since 9/11, particularly films, have played an important role in the conception and circulation of provocative views about Muslims. Following 9/11, disturbing images of Arabs and Muslims became predominant in Hollywood and Bollywood cinema. The Muslim community worldwide was highly affected by the way films portrayed them in a constant demeaning manner. This thesis investigates the stereotyped Muslim depictions in the Hollywood and Bollywood film industries and reveals how the 9/11 attacks shaped these portrayals on the screen in selected movies: The Kingdom (2007) and Kurbaan (2009). It traces the history of Muslim representations pre- and post-9/11 and highlights the major stereotypes that were associated with Muslims. Scholars have investigated the nature of these portrayals, but little research on how these representations affected audiences was conducted in the area of reception studies. The thesis will examine how Muslims are portrayed in these films in order to identify representational trends that promote deteriorating images of Muslims and how these images shaped audiences’ perceptions. It explores the social, historical, and political contexts to understand the way the process of representation began and how images and meanings about Muslims were interpreted by audiences. This thesis contends that post-9/11 Hollywood and Bollywood representations of Muslims were highly stereotyped, with Muslim characters being portrayed as terrorists. Topics of Islamophobia, terrorism, and Western perceptions of Muslim women, particularly within the context of the war on terror, are discussed to provide a better understanding of how misconceptions about Muslims gained prominence in the film industry. The research comprises two case studies, each of which analyses a film produced post-9/11. These films have in common the fact that they both evoke the context of the war on terror and illustrate the way both film industries cast Muslims in a degrading manner. For this, the research uses a reception study to trace audiences’ interpretation and engagement with representations in films. The study combines critics’ and users’ reviews collected on Metacritic and IMDB, respectively, to identify how films frame audiences’ opinions about Muslims. This thesis demonstrates that both the Hollywood and Bollywood film industries contributed to the conception, promotion and circulation of stereotypes and misconceptions about Muslims. In the post-9/11 context, the industries’ depictions have Othered this group and shaped audiences’ perceptions of Muslims as terrorists. This research has attempted to identify and challenge the existing and recurring generalisations in two of the world’s biggest cinematic industries and reveals that Muslim depictions are mostly unbalanced despite the industries’ efforts to enhance these portrayals.

description: We present a method for computing the flux of energy through a closed surface containing a gravitating system. This method, which is based on the quasilocal formalism of Brown and York, is illustrated by two applications: a calculation of (i) the energy flux, via gravitational waves, through a surface near infinity and (ii) the tidal heating in the local asymptotic frame of a body interacting with an external tidal field. The second application represents the first use of the quasilocal formalism to study a non-stationary spacetime and shows how such methods can be used to study tidal effects in isolated gravitating systems.
