description: Toxoplasma gondii, a worldwide prevalent parasite is responsible for causing toxoplasmosis in almost all warm-blooded animals, including humans. Golgi-resident T. gondii aspartic protease 5 (TgASP5) plays an essential role in the maturation and export of the effector proteins those modulate the host immune system to establish a successful infection. Hence, inhibiting this enzyme can be a possible therapeutic strategy against toxoplasmosis. This is the first report of the detailed structural investigations of the TgASP5 mature enzyme using molecular modeling and an all-atom simulation approach which provide in-depth knowledge of the active site architecture of TgASP5. The analysis of the binding mode of the TEXEL (Toxoplasma EXport Element) substrate to TgASP5 highlighted the importance of the active site residues. Ser505, Ala776 and Tyr689 in the S2 binding pocket are responsible for the specificity towards Arg at the P2 position of TEXEL substrate. The molecular basis of inhibition by the only known inhibitor RRLStatine has been identified, and our results show that it blocks the active site by forming a hydrogen bond with a catalytic aspartate. Besides that, known aspartic protease inhibitors were screened against TgASP5 using docking, MD simulations and MM-PBSA binding energy calculations. The top-ranked inhibitors (SC6, ZY1, QBH) showed higher binding energy than RRLStatine. Understanding the structural basis of substrate recognition and the binding mode of these inhibitors will help to develop potent mechanistic inhibitors against TgASP5. This study will also provide insights into the structural features of pepsin-like aspartic proteases from other apicomplexan parasites for developing antiparasitic agents.

description: In this study, monobrominated coumarins (5–6) and bis-coumarins (7–9) were synthesized from 3-carboxylic coumarin and 7-hydroxy-4-methyl coumarin using 1,4-dibromobutane as a binding agent, according to the synthesis procedures described in the literature. Amongst these coumarins, three are new compounds: monobrominated coumarin 5 and bis-coumarins 7 and 9. The structures of the synthesized coumarins were confirmed by FTIR, NMR and HRMS-ESI. In vitro antimicrobial evaluation of these coumarins against strains of twelve bacteria and four fungi revealed their bactericidal and fungicidal properties, with increased antibacterial activity for monocoumarins and improved antifungal activity for bis-coumarins. It was also found that the antibacterial activity was enhanced by the etheric bond, Br atom and alkyl chain and reduced by the ester bonds at position 3 of the pyrone ring or an additional coumarin unit, while the antifungal activity was reinforced by ester bonds and deactivated by the Br atom. For the first time, the in silico investigations of such coumarins were carried out and it was observed that they are less toxic, suitable for oral administration with good permeability through cell membrane, are able to circulate freely in the bloodstream and cross Blood-Brain-Barriers. Moreover, their molecular docking in DNA indicated stable coumarin-DNA complexes with good scores. The results of molecular dynamics simulations performed for 200 ns revealed the rigidity and stability of bis-coumarins (7–9) in the DNA binding pocket and predict that they are potent binders.

description: Collective Rydberg excitations provide promising applications ranging from quantum information processing, and quantum computing to ultra-sensitive electrometry. However, their short lifetime is an immense obstacle in real-life scenarios. The state-of-the-art methods of prolonging the lifetime were mainly implemented for ground-state quantum memories and would require a redesign to effectively work on different atomic transitions. We propose a protocol for extending the Rydberg excitation lifetime, which in principle can freeze the spin-wave and completely cancel the effects of thermal dephasing. The protocol employs off-resonant ac-Stark lattice modulation of spin waves by interfering two laser beams on the atomic medium. Our implementation showed that the excitation lifetime can be extended by an order of magnitude, paving the way towards more complex protocols for collective Rydberg excitations.

description: Iron acquisition is critical to the virulence of Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis. To acquire iron within the host, Mtb secretes siderophores that chelate iron with high affinity. Siderophores scavenge iron from host cells using TonB-dependent transporters like FecA. We investigated molecular mechanisms of FecA-mediated ferric-siderophore transport in Mtb. Molecular docking and molecular dynamics simulations revealed a series of interactions between ferric siderophores and FecA. The initial binding occurs at a pocket located on the extracellular surface of FecA. The ligand then migrates deeper through the transport tunnel to a subsequent binding site, aided by conformational changes in FecA that expand the tunnel diameter. We observed the key roles of precise positioning of extracellular loops in the outer membrane barrel and plug domains in the optimal ligand binding and transport. Transport of ferric–siderophore complex into Mtb follows an induced fit model, with ligand interaction eliciting 2–10 Å shifts in the barrel and plug regions. By revealing the conformational dynamics enabling iron import, these findings provide molecular-level insights into a metal ion uptake mechanism in Mtb. Iron acquisition is essential for Mtb pathogenesis, so this work may inform novel therapeutic strategies that disrupt siderophore uptake pathways.

description: Looking at how social values are represented in fairy tales can give insights about the variations in communication of values across cultures. We study how values are communicated in fairy tales from Portugal, Italy and Germany using a technique called word embedding with a compass to quantify vocabulary differences and commonalities. We study how these three national traditions differ in their explicit references to values. To do this, we specify a list of value-charged tokens, consider their word stems and analyse the distance between these in a bespoke pre-trained Word2Vec model. We triangulate and critically discuss the validity of the resulting hypotheses emerging from this quantitative model. Our claim is that this is a reusable and reproducible method for the study of the values explicitly referenced in historical corpora. Finally, our preliminary findings hint at a shared cultural understanding and the expression of values such as Benevolence, Conformity, and Universalism across the studied cultures, suggesting the potential existence of a pan-European cultural memory.

description: Abietatrien-3β-ol (ATO) was isolated from the aerial part of the Nepeta italica subsp. italica methanol-chloroform extract and studied antioxidant, enzyme inhibition, and DNA protection activities. The plant extract was fractionated by silica gel column chromatography using four different solvents. After the active chloroform fraction was divided into six subfractions under the guidance of bioactivity, ATO was isolated from the fourth active subfraction. The molecular structure of ATO was determined by the NMR techniques and confirmed with literature data. In the antioxidant test, ATO showed excellent DPPH˙ (IC50-1.18 ± 0.11 µg/mL), ABTS˙+ (IC50-1.82 ± 0.00 µg/mL), metal chelating (IC50-2.90 ± 0.05 µg/mL), superoxide anion scavenging (IC50-11.59 ± 0.27 µg/mL), reducing power (A0.5-21.09 ± 1.42 µg/mL), H2O2 (A0.5-57.81 ± 4.54 µg/mL), and phosphomolybdenum reducing (A0.5-124.23 ± 0.69 µg/mL) activities when compared to standards. The DNA protection potential was also found to be strong in Form I (47.89%) and Form II (4.56%) formations. ATO had high inhibitions in AChE (IC50-1.25 ± 0.04 µg/mL), BChE (IC50-1.26 ± 0.03 µg/mL), lipase (IC50-7.58 ± 0.27 µg/mL), and tyrosinase (IC50-9.60 ± 0.03 µg/mL). In molecular docking studies, ATO had a high binding affinity with α-amylase (−8.80 kcal/mol), tyrosinase (−8.10 kcal/mol), and urease (−8.10 kcal/mol) enzymes. In addition, by detailing the interaction of ATO with key enzymes that give the best interactions through molecular docking studies, with molecular dynamics studies, and by performing ADMET and DFT calculations, it was tried to explain that it could be a suitable drug candidate. In light of these studies, ATO is thought to be an effective enzyme inhibitor and a protective molecule against oxidation with its active antioxidant properties.

description: A combination of fifteen top quark mass measurements performed by the ATLAS and CMS experiments at the LHC is presented. The data sets used correspond to an integrated luminosity of up to 5 and 20$^{-1}$ of proton-proton collisions at center-of-mass energies of 7 and 8 TeV, respectively. The combination includes measurements in top quark pair events that exploit both the semileptonic and hadronic decays of the top quark, and a measurement using events enriched in single top quark production via the electroweak $t$-channel. The combination accounts for the correlations between measurements and achieves an improvement in the total uncertainty of 31% relative to the most precise input measurement. The result is $m_\mathrm{t}$ = 172.52 $\pm$ 0.14 (stat) $\pm$ 0.30 (syst) GeV, with a total uncertainty of 0.33 GeV.

description: The determination of network related risks for transport infrastructure systems, such as road or railway networks, is a challenging task. Due to such complex systems, it is generally impossible to abstract the global behavior from the analysis of single components, especially under conditions such as failures or damages. People who manage infrastructure have to handle these risks. The proposed overarching risk assessment process is constructed in a way so that computational support can be constructed in modules. This allows to couple the process with detailed sub-processes to achieve varying levels of detail in the risk assessment. The use of the overarching risk assessment process is demonstrated by using it to evaluate infrastructure related risk due to natural hazards for an example region in Switzerland.

description: We investigate the first-order phase transition catalyzed by primordial black holes~(PBHs) in the early Universe. We find that super-horizon curvature perturbations generated in this scenario lead to the production of gravitational waves when the scalar modes re-enter the horizon. If PBHs with masses about $10^{-13}M_{\odot}$ constitute all dark matter, the first-order electroweak phase transition catalyzed by PBHs can explain the gravitational wave signal observed by pulsar timing array collaborations without the overproduction of PBHs.

description: Recent work has highlighted the utility of methods for early warning signal detection in dynamic systems approaching critical tipping thresholds. Often these tipping points resemble local bifurcations, whose low dimensional dynamics can play out on a manifold embedded in a much higher dimensional state space. In many cases of practical relevance, the form of this embedding is poorly understood or entirely unknown. This paper explores how measurement of the critical phenomena that generically precede such bifurcations can be used to make inferences about the properties of their embeddings, and, conversely, how prior knowledge about the mechanism of bifurcation can robustify predictions of an oncoming tipping event. These modes of analysis are first demonstrated on a simple fluid flow system undergoing a Hopf bifurcation. The same approach is then applied to data associated with the West African monsoon shift, with results corroborated by existing models of the same system. This example highlights the effectiveness of the methodology even when applied to complex climate data, and demonstrates how a well-resolved spatial structure associated with the onset of atmospheric instability can be inferred purely from time series measurements.

Challenges and obstacles facing tenderers adopting e-tendering in the public sector of the construction industry in Egypt
Creators: name: Khalil, Cherif A.
name: Waly, Ahmed F.
Publisher: name: The University of British Columbia
Year: 2015

description: The construction public sector in Egypt, like most countries in the world, is tendering its projects through the traditional paper-based tendering procedure, which has many weaknesses including bureaucracy and lack of transparency. Due to the considerable volume of projects tendered each year, it was essential to study the possibility of implementing another more efficient mechanism “E-Tendering” that overcomes the drawbacks of the paper-based tendering procedure. This on-going research examines the readiness of the construction industry in Egypt to adopt E-Tendering for public tenders and provides recommendations to improve its uptake. This paper provides a model of the barriers, challenges and concerns of the Egyptian tenderers towards accepting and adopting E-Tendering. This is accomplished through extensive review of the literature together with expert identification and analysis. 19 challenges are highlighted and categorized into 4 categories: security challenges, user acceptance and staff resistance, accessibility issues and legal barriers. These challenges are then examined and ranked with respect to their importance by a panel of academic and industry experts to reflect the Egyptian public tendering context. The most important highlighted barriers are the SMEs access difficulties, the expected technical malfunctioning of the portal, the reluctance/resistance to change and the breach of confidentiality of information. These findings present a cornerstone in the development of a framework that presents practical solutions to the success of E-Tendering for the construction public projects in Egypt.

description: Due to excess of resource consumption, circular economy (CE) aims to return products to the production life cycle in an economically and ecologically reasonable way. Yet, few approaches focus on the strategic and network level of CE. First, existing approaches regarding the configuration of CE networks and the development of appropriate business models are reviewed. Second, an approach on how to integrate both aspects is presented. By integrating these aspects, implementation strategies for CE in global production networks shall be developed facilitating strategic decisions. The approach is planned to be demonstrated in a German company supplying the automotive sector.

description: For a finite-dimensional vector space $V$, the common basis complex of $V$ is the simplicial complex whose vertices are the proper non-zero subspaces of $V$, and $σ$ is a simplex if and only if there exists a basis $B$ of $V$ that contains a basis of $S$ for all $S\in σ$. This complex was introduced by Rognes in 1992 in connection with stable buildings. In this article, we prove that the common basis complex is homotopy equivalent to the proper part of the poset of partial direct sum decompositions of $V$. Moreover, we establish this result in a more general combinatorial context, including the case of free groups, matroids, vector spaces with non-degenerate sesquilinear forms, and free modules over commutative Hermite rings, such as local rings or Dedekind domains.

On some dynamical features of the complete Moran model for neutral evolution in the presence of mutations
Creators: name: Gaeta, Giuseppe
Publisher: name: arXiv
Year: 2024
Subjects: subject: Populations and Evolution (q-bio.PE)
subject: Probability (math.PR)
subject: FOS: Biological sciences
subject: FOS: Mathematics

description: We present a version of the classical Moran model, in which mutations are taken into account; the possibility of mutations was introduced by Moran in his seminal paper, but it is more often overlooked in discussing the Moran model. For this model, fixation is prevented by mutation, and we have an ergodic Markov process; the equilibrium distribution for such a process was determined by Moran. The problems we consider in this paper are those of first hitting either one of the ``pure'' (uniform population) states, depending on the initial state; and that of first hitting times. The presence of mutations leads to a nonlinear dependence of the hitting probabilities on the initial state, and to a larger mean hitting time compared to the mutation-free process (in which case hitting corresponds to fixation of one of the alleles).

description: In this paper, we mainly predict the rates of $M$1 radiative and spin-nonflip $ππ$ transitions of the $B_{c}$-meson under the nonrelativistic Cornell potential model with a screening potential effect. We employ the numerical wave function to determine the $M$1 radiative transition widths of $B_c$ excited states and utilize the Kuang-Yan proposed method for the spin-nonflip $ππ$ transitions among $B_c$ states. Our theoretical results are valuable for studying the $M$1 radiative and spin-nonflip $ππ$ transition processes of $B_c$ states in experiments.

description: In February 2005 the USAF initiated project-related Section 106 consultation with SHPD, Hui Malama, and the office of Hawaiian Affairs (OHA), recommending a project related archaeological monitoring program based on the project's potential to encounter significant cultural resources including human burials and buried cultural layers related to traditional Native Hawaiian land use. CSH prepared the project's monitoring plan (Hammatt et al. 2005), which SHPD accepted (Log No 2005 .2A9Y Doc No 0509NM39). The monitoring plan called for on-site monitoring of all project related ground disturbance. No significant cultural resources were documented during the monitoring fieldwork.
Make Interaction Situated: Designing User Acceptable Interaction for Situated Visualization in Public Environments

description: Situated visualization blends data into the real world to fulfill individuals' contextual information needs. However, interacting with situated visualization in public environments faces challenges posed by user acceptance and contextual constraints. To explore appropriate interaction design, we first conduct a formative study to identify user needs for data and interaction. Informed by the findings, we summarize appropriate interaction modalities with eye-based, hand-based and spatially-aware object interaction for situated visualization in public environments. Then, through an iterative design process with six users, we explore and implement interactive techniques for activating and analyzing with situated visualization. To assess the effectiveness and acceptance of these interactions, we integrate them into an AR prototype and conduct a within-subjects study in public scenarios using conventional hand-only interactions as the baseline. The results show that participants preferred our prototype over the baseline, attributing their preference to the interactions being more acceptable, flexible, and practical in public.

description: The Portuguese School of Extremes and Applications is nowadays well recognised by the international scientific community, and in my opinion, the organisation of a NATO Advanced Study Institute on Statistical Extremes and Applications, which took place at Vimeiro in the summer of 1983, was a landmark for the international recognition of the group. The dynamic of publication has been very high and the topics under investigation in the area of Extremes have been quite diverse. In this article, attention will be paid essentially to some of the scientific achievements of the author in this field.
