Restructuring the interfacial active sites to generalize the volcano curves for platinum-cobalt synergistic catalysis

Computationally derived volcano curve has become the gold standard in catalysis, whose practical application usually relies on empirical interpretations of composition or size effects by the identical active site assumption. Here, we present a proof-of-concept study on disclosing both the support- and adsorbate-induced restructuring of Pt-Co bimetallic catalysts, and the related interplays among different interfacial sites to propose the synergy-dependent volcano curves. Multiple characterizations, isotopic kinetic investigations, and multiscale simulations unravel that the progressive incorporation of Co into Pt catalysts, driven by strong Pt-C bonding (metal-support interfaces) and Co-O bonding (metal-adsorbate interfaces), initiates the formation of Pt-rich alloys accompanied by isolated Co species, then Co segregation to epitaxial CoOx overlayers and adjacent Co3O4 clusters, and ultimately structural collapse into amorphous alloys. Accordingly, three distinct synergies, involving lattice oxygen redox from Pt-Co alloy/Co3O4 clusters, dual-active sites engineering via Pt-rich alloy/CoOx overlayer, and electron coupling within exposed alloy, are identified and quantified for CO oxidation (gas-phase), ammonia borane hydrolysis (liquid-phase), and hydrogen evolution reaction (electrocatalysis), respectively. The resultant synergy-dependent volcano curves represent an advancement over traditional composition-/size-dependent ones, serving as a bridge between theoretical models and experimental observations in bimetallic catalysis.

Deformation Mechanisms During the Syn‐Orogenic Extrusion of the High‐Pressure Phyllites‐Quartzites Unit in the Central and Northern Peloponnese, Greece

AbstractThe High‐Pressure Phyllites‐Quartzites (PQ) unit of the External Hellenides is exposed in tectonic windows in the central and northern Peloponnese (Greece). Understanding the deformation history of this unit is essential to interpreting the Oligo‐Miocene evolution of the External Hellenides belt and its associated exhumation events. This study integrates new field observations and microtectonic analyses with previous studies to offer a comprehensive deformation model of the PQ unit since the Late Oligocene. The first deformation phase (D1), captures the progressive incorporation of the PQ into an orogenic wedge. This phase is largely overprinted and only preserved as relict features. The second phase (D2) displays coeval top‐to‐the‐ENE and top‐to‐the‐WSW localized ductile shear. A transition is observed from top‐to‐the‐ENE non‐coaxial deformation at the upper parts of the nappe to intense isoclinal folding (refolding S1) at the lower structural levels. We associate D2 with the ductile syn‐orogenic exhumation of the PQ within an extrusion wedge, accompanied by greenschist‐facies retrogression. In the third phase (D3), semi‐brittle to brittle extensional fault planes cut through the previous ductile structures. D3 faults exhibit extensional kinematics in all directions on the flanks of exhumation domes. This phase correlates with a late‐orogenic doming event, marking the final exhumation stage of the PQ unit in the upper crust. The exhumation of high‐pressure units results from the interplay between ductile syn‐orogenic extrusion and continuous underplating within the subduction zone. This underplating maintains vertical movements and uplift of the units, initiating a 3D upper‐crustal extensional collapse along low‐angle normal faults.

Nietzsche’s holy jest: the ambivalence of laughter in thus spoke zarathustra

ABSTRACT This paper offers an interpretation of Thus Spoke Zarathustra as Nietzsche’s attempt to write a ‘holy book’ that sanctifies laughter. I compare two important scenes, that of the jester and ropedancer from the Prologue, and that of the ‘ass festival’ from part IV, to show the progressive incorporation of laughter into Zarathustra’s teaching. Throughout, I show that laughter in Zarathustra is ambivalent, possessing both critical and constructive elements. As such, the laughter that is celebrated by the end of the Fourth Part is not merely ironic and self-parodying, but also constitutes a teaching with positive content. In other words, laughter itself represents the heart of Nietzsche’s new revelation of ‘holiness,’ one that challenges regnant expressions of religion and piety while resisting serious, doctrinal formulation. I defend this interpretation against readings that recruit laughter toward a modest philosophical ideal of self-ironization. While laughter does parody and destabilize Zarathustra’s own teachings, it also animates a teaching of holiness that can be helpfully illuminated by Bakhtin’s theory of the carnivalesque. In closing, I suggest that scholars should respect the ‘religion-like’ ambitions of Nietzsche’s work rather than assimilating them to the more modest projects typical of modern scholarship.

Architecture Competitions as an Opportunity for Young Women Architects. The Case of the Competition for Rural Subsidised Housing and the Canarian Magüi González, 1981-85

The Spanish democratic transition (1975-1982) was a time when architecture competitions with open and anonymous participation gradually began to appear, a phenomenon that coincided with the progressive incorporation of women architects into the discipline. The first part of this article analyses the situation of these competitions by studying their repercussions in 16 Spanish professional architectural journals belonging to both consolidated and emerging Spanish Architects’ Associations. The participation of women architects is also analysed in order to assess whether these competitions were a source of professional opportunities for them. In the second section, the article studies the Competition for Architectural Solutions for Officially Subsidised Single-Family Housing in Rural Areas (1981-83), a nationwide call with the most significant participation of architecture professionals (more than 1.000) and with a notable number of selected proposals by women architects. This study shows that women architects working in peripheral areas of the Spanish territory had a special presence in this competition, with the Canary Islands being the most remarkable case, for both the good results of its female participants and its ultra-peripheral location. Among the participating women architects, Magüi González stands out for the quality of her proposal and for being the only female professional who eventually obtained a commission from this competition. Finally, the investigation focuses, from a compositional, constructive and design culture perspective, on González’s final built project: 30 dwellings in Juan Grande in Las Palmas de Gran Canaria (1983-85), which was, indeed, her opera prima and was eventually awarded an important regional architecture prize.

Measuring population health using health expectancy estimates from morbidity and mortality databases.

The progressive incorporation of quality of life indicators in health planning meets a critical need: The evaluation of the performance of health services, which are under stress by multiple causes, but in particular by an ageing population. In general, national health plans rely on health expectancies obtained using the Sullivan method. The Sullivan health expectancy index combines age-specific mortality rates and age-specific prevalence of healthy life, obtained from health surveys. The objective of this work is to investigate an equivalent estimation, using available information from morbidity and mortality datasets. Mortality and morbidity information, corresponding to years 2016 and 2017, was obtained for the population of the county of Baix Empordà (Catalonia), N = 91,130. Anonymized individual information on diagnoses, procedures and pharmacy consumption contained in the individual clinical record (ICD and ATC codes), were classified into health states. Based on the observed health transitions and mortality, life expectancies by health state were obtained from a multistate microsimulation model. Healthy life expectancies at birth and 65 years for females and males were respectively HLE0female = 39.94, HLE0male = 42.87, HLE65female = 2.43, HLE65male = 2.17. These results differed considerably from the Sullivan equivalents, e.g., 8.25 years less for HLE65female, 9.26 less for HLE65male. Point estimates for global life expectancies at birth and 65 years of age: LE0female = 85.82, LE0male = 80.58, LE65female = 22.31, LE65male = 18.86. Health indicators can be efficiently obtained from multistate models based on mortality and morbidity information, without the use of health surveys. This alternative method could be used for monitoring populations in the context of health planning. Life Expectancy results were consistent with the standard government reports. Due to the different approximation to the concept of health (data-based versus self-perception), healthy life expectancies obtained from multistate micro simulation are consistently lower than those calculated with the standard Sullivan method.

Ferroelectric-assisted enhancement of the photocatalytic activity of g-C3N4/TiO2 nanotubes heterojunctions through the addition of strontium

The effect of adding strontium to nanocomposites formed of g-C3N4/TiO2 nanotubes (TiNT) (g-C3N4: 4.0 wt%) on the photocatalytic activity was herein investigated using formic acid as a model target pollutant. g-C3N4 material was prepared by a solvothermal method using a mixture of urea and cyanuric chloride as precursors and acetonitrile as a solvent at 220 °C for 15 h, while TiNT material was obtained by the alkaline hydrothermal method of P25 at 130 °C for 20 h. A series of xSr-gC3N4/TiNT nanocomposites were then synthesized through progressive incorporation of strontium (from 0.2 to 1.0 wt%) at the surface of the composites. Samples were then characterized mainly using N2 adsorption–desorption measurements, X-ray diffraction, UV–vis diffuse reflectance, Raman and photoluminescence (PL) spectroscopies, and scanning and transmission electron microscopy (with energy-dispersive X-ray spectroscopy and Z-mapping). The Sr-containing g-C3N4/TiNT composites were then also fully characterized by electrochemical impedance spectroscopy (EIS) for their dielectric properties, while a deep kinetics analysis was also performed. Such an approach allowed us to establish a correlation between photocatalytic performance and the material's propensity to be polarized. Results emphasize the beneficial role of ferroelectricity induced by adding strontium. Indeed, enhancement of the photocatalytic activity by 2.3 times compared to a Sr-free counterpart was related to the material's ability to be polarized for Sr loadings ≤ 0.6 wt%. At higher Sr loadings, supplementary factors (decrease of the anatase crystallinity, formation of TiO2(B), disruption of the g-C3N4/TiO2 interaction, or lower mobility of photogenerated charges) negatively impact the activity, counterbalancing partly the beneficial ferroelectric effect. In this way, this study emphasizes the role played by ferroelectric effects in enhancing the photocatalytic ability of a given semiconductor.

Visualizing chaperone-mediated multistep assembly of the human 20S proteasome

Dedicated assembly factors orchestrate the stepwise production of many molecular machines, including the 28-subunit proteasome core particle (CP) that mediates protein degradation. Here we report cryo-electron microscopy reconstructions of seven recombinant human subcomplexes that visualize all five chaperones and the three active site propeptides across a wide swath of the assembly pathway. Comparison of these chaperone-bound intermediates and a matching mature CP reveals molecular mechanisms determining the order of successive subunit additions, as well as how proteasome subcomplexes and assembly factors structurally adapt upon progressive subunit incorporation to stabilize intermediates, facilitate the formation of subsequent intermediates and ultimately rearrange to coordinate proteolytic activation with gated access to active sites. This work establishes a methodologic approach for structural analysis of multiprotein complex assembly intermediates, illuminates specific functions of assembly factors and reveals conceptual principles underlying human proteasome biogenesis, thus providing an explanation for many previous biochemical and genetic observations.

Synthesis, optical, and spectroscopic studies of bismuth boro-tellurite glass system containing BaO and V2O5

A melt quenching technique was used for the preparation of xBaO–(30-x)TeO2–35Bi2O3–33B2O3–2V2O5 (5 ≤ x ≤ 25 mol%) glasses. The structural modifications are studied by X-ray diffraction, DSC, optical, infrared spectroscopy, and Raman as a function of BaO mol%. The progressive incorporation of BaO mol% in the BTBiBV glasses decreases the optical band gap values as the number of free electrons increases with the creation of additional NBOs. The FTIR spectra of the prepared glasses consist of BO3 trigonal and BO4 tetrahedral units while TeO2 changes to TeO3 andTeO4 structural units. The Raman spectra shows that the replacement of BaO with TeO2 decreases the concentration of Te–O–Te linkages within the volume of host glass, which increases the concentration of Ba–O–Te linkages along with BO3 units. Due to this, the overall glass formers connectivity decreases which intern to the creation of NBOs. Moreover, the research highlighted that BTBiBV-5 glasses have exceptional optical properties making them promising materials for photonics, optoelectronics, and optical communication device applications.

How does Coloured Lighting Influence the Affective Processes of Pupils?

Nowadays, the progressive incorporation of technological elements in classrooms adds new possibilities to be explored in the field of colour and environment. In this sense, LED lighting as a source of “coloured light” is a resource that has not yet been analysed. The present quasi-experimental design had a pre-test and was carried out for a single group in a primary school for two months, focusing on the dependent variables “energy level”, “enjoyment level” and “feeling”, whose values were collected by means of a self-perception survey. The results obtained are significant in the post hoc analysis of variance for some scenarios of the variable “feelings”, but less so for the others. The disparity of results according to the colour analysed, with violet sometimes having a greater impact than orange at other times, also leads us to consider the need for dynamism positively.

Metal-Free, Bio-Triboelectric Nanogenerator Based on a Single Electrode of Bacterial Cellulose Modified with Carbon Black

Developing metal-free electrodes for prototypes of bio-based devices is an essential step in producing non-toxic components for implantable devices and wearables. In particular, the advancement in self-powered devices is a hot topic for several applications due to the possibility of creating free-battery devices and sensors. In this paper, the modification of bacterial cellulose by the progressive incorporation of carbon black (a conductive filler) was explored as a prototype for bio-based electrodes for triboelectric nanogenerators. This process was controlled by the percolation pathways’ activation through the contact of carbon black grains with the bacterial cellulose membrane, which represents a critical step in the overall process of optimization in the power output performance, reaching an open circuit voltage value of 102.3 V, short circuit current of 2 μA, and power density of 4.89 μW/cm2.

It underscores the transformative potential of RGB-D and LSD-SLAM systems, underscores the significance of interaction interfaces, and underscores the evolving trajectory towards a more inclusive and efficient navigation solution for the visually impaired.

Quantitative in situ synchrotron X-ray analysis of the ALD/MLD growth of transition metal dichalcogenide TiS2 ultrathin films.

We present the results of a full quantitative analysis of X-ray absorption spectroscopy (XAS) performed in situ during the growth of ultrathin titanium disulfide (TiS2) films via an innovative two-step process, i.e. atomic layer deposition/molecular layer deposition (ALD/MLD) followed by annealing. This growth strategy aims at separating the growth process from the crystallization process by first creating an amorphous Ti-thiolate that is converted later to crystalline TiS2via thermal annealing. The simultaneous analysis of Ti and S K-edge XAS spectra, exploiting the insights from density functional theory calculations, allows us to shed light on the chemical and structural mechanisms underlying the main steps of growth. The nature of the bonding at the base of the interface creation with the SiO2 substrate is disclosed in this study. Evidence of a progressive incorporation of S in the amorphous Ti-thiolate is given. Finally, it is shown that the annealing step plays a critical role since the transformation of the Ti-thiolate into nanocrystalline TiS2 and the loss of S are simultaneously induced, validating the two-step synthesis approach, which entails distinct growth and crystallization steps. These observations contribute to a deeper understanding of the bonding mechanism at the interface and provide insights for future research in this field and the generation of ultra-thin layered materials.

Information from 2040 patients was analyzed. Results: 604 patients (29.6%) received novel agents in both intensive and non-intensive setting. Comorbidities were not a barrier for the use of novel agents. The presence of tumor mutations was observed to be an important element for treatment decision. Conclusion: There is a progressive incorporation of novel agents for newly diagnosed acute myeloid leukemia patients.

Short-Term Evaluation of Bone-ACL-Bone Complex Allograft in ACL Reconstruction in a Rabbit Model.

The study is to evaluate incorporation of a bone-anterior cruciate ligament-bone (B-ACL-B) allograft in anterior cruciate ligament (ACL) reconstruction in a rabbit model. A total of 61 New Zealand white rabbits were used, with 23 donor rabbits for harvesting B-ACL-B allografts and 38 recipient rabbits undergoing unilateral ACL reconstruction with B-ACL-B allograft. Animals were euthanized for biomechanical testing, micro-computed tomography examination, histological analysis, multi-photon microscopy and transmission electron microscopy testing at 2, 4 and 8 weeks after surgery. Gross inspection and radiographs confirmed the intact ACL allograft in the proper anatomic position. Progressive healing occurred between the bone block and the bone tunnel as demonstrated by a gradual increase in average bone volume fraction and total mineral density at 4 and 8 weeks. Histological analysis showed new bone formation at the bone block-tunnel interface, with maintenance of the native ACL enthesis. Ultrastructural analysis demonstrated the maintenance of overall collagen matrix alignment, while there was repopulation with smaller diameter collagen fibrils. There was no significant difference between 4 and 8 weeks in mean failure force (p = 0.39) or stiffness (p = 0.15) for the B-ACL-B allografts. This study demonstrates the restoration of the normal anatomy of the ACL and progressive graft incorporation and remodeling using a B-ACL-B allograft for ACL reconstruction in the rabbit knee.

The nickel output to abyssal pelagic manganese oxides: A balanced elemental and isotope budget for the oceans

The development of nickel isotopes as a chemical tracer of past ocean environments requires a sound understanding of the modern oceanic budget. Our current understanding of this budget implies a large elemental and isotope imbalance between inputs to and outputs from the dissolved pool of the ocean. This imbalance is mainly caused by the dominant oxic sink of Ni to Mn oxide-rich sediments. Though the Ni isotope composition of Fe-Mn crusts has previously been used as proxy for the Ni isotope composition of these sediments, crusts and nodules represent a very small part of the total Mn oxide output. Instead, Mn oxide microparticle supply to pelagic and hemi-pelagic sediments dominates the removal of Mn to sediments, but there are very few isotope data for such samples. Here we present the first extensive Ni concentration and isotope dataset from fully oxic Mn-rich pelagic sediments, from 6 different sites across the open Pacific and 10 closely-spaced sites in the Indian Ocean. We also present data for one hemi-pelagic site representing a suboxic setting on the California Margin. Abyssal Pacific and Indian Ocean sediments have a Ni/Mn ratio of 0.02 (similar to Fe-Mn crusts) and their authigenic Ni is isotopically lighter (δ60Ni = +0.26 to +1.08‰) than seawater (+1.33‰) and crusts (+1.55±0.38‰). Data presented here for organic carbon-rich suboxic sediments of the Californian margin have lower Ni/Mn ratios (0.004 to 0.014 for the oxic top of the core, where Mn oxide is present in abundance) and even lighter authigenic Ni isotope compositions (δ60Ni = -0.08±0.11‰).We show that the Ni isotopes of nearly all Mn-rich sediments and deposits analysed to date, including the new data presented here, are correlated with Co/Mn ratios, suggesting that both are controlled by accumulation rate, progressive incorporation of Ni into the metal oxide structure and isotopic re-equilibration between the solid and aqueous phase. At sites where sediments are diagenetically processed, such as the California Margin, differential diagenetic remobilisation of Mn, Ni and Co cause deviations from this correlation. We present a new mass balance calculation that recognises the importance of scavenging of oceanic Ni to Mn oxide-rich proximal hydrothermal sediments, with low Ni/Mn and light isotope compositions. The mass balance produces a budget that can be simultaneously balanced for both amounts and isotope compositions of Ni. This result provides a strong basis for the application of Ni isotopes as records of the evolution of the metal sink from the oxic oceans through Earth history.

Space Sex-Machines: trans-planetary ethics and the mediatization of things

The progressive incorporation of devices, infrastructures, and interfaces in the communications ecosystems has provoked a transformation in the research fields too. Mediatization research for instance has started to incorporate data infrastructures, deep mediatization, and robots in the theoretical discussion. This paper roots in this trend by suggesting a field on mediatization of things that encompasses three areas: the considerations on human-machine assemblages, the entanglements at planetary scale of the material and environmental costs of connection, and the discussion about care and humanity as fundamental kin relational values. These three dimensions overlap, interact, and activate profound and critical ethical debates necessary to contribute to the discussions on long-duration space exploration, affective relations with machines, and for inter-species planet reproduction. Sex-machines are at the centre of these human-caring-beings and inter-planetary-networks; in this research we study the six types of sex-machines against the space-travelling conditions. This contribution reveals the urgency of establishing the field of Space Robot Ethics, including the discussion of Mediatized Intimacies and sexuality in space. This paper illustrates that robots and sex-machines are complex multi-agent networks of distributed responsibility; and reviewing the governance of their designs, and threat modelling their ethical and safety and security features not only anticipates more pleasant outer space travels, but also helps preparing for an earthy life with robots.

Real-world genomic profiling of acute myeloid leukemia and the impact of European LeukemiaNet risk stratification 2022 update.

Acute myeloid leukemia (AML) is a myeloid neoplasm associated with a high morbidity and mortality. The diagnosis, risk stratification and therapy selection in AML have changed substantially in the last decade with the progressive incorporation of clinically relevant molecular markers. In this work, our aim was to describe a real-world genomic profiling experience in AML and to demonstrate the impact of the European Leukemia Net 2022 update on risk stratification in AML. One hundred and forty-one patients were evaluated with an amplicon-based multi-gene next-generation sequencing (NGS) panel. The most commonly mutated genes were FLT3, DNMT3A, RUNX1, IDH2, NPM1, ASXL1, SRSF2, NRAS, TP53 and TET2. Detection of FLT3 ITD with NGS had a sensitivity of 96.3% when compared to capillary electrophoresis. According to ELN 2017, 26.6%, 20.1%, and 53.3% of patients were classified as having a good, moderate, or unfavorable risk. When ELN 2022 was used, 15.6%, 27.8%, and 56.6% of patients were classified as favorable, moderate, or unfavorable risk, respectively. When ELN 2022 was compared to ELN 2017, thirteen patients (14.4%) exhibited a different risk classification, with a significant decrease in the number of favorable risk patients, what has immediate clinical impact. In conclusion, we have described a real-world genomic profiling experience in AML and the impact of the 2022 ELN update on risk stratification.

Effect of Composition and Freeze-Thaw on the Network Structure, Porosity and Mechanical Properties of Polyvinyl-Alcohol/Chitosan Hydrogels.

We report the synthesis and characterization of poly (vinyl alcohol) (PVA)/Chitosan (CT) cryogels for applications involving the uptake and entrapment of particulate and bacterial colonies. In particular, we systematically investigated the network and pore structures of the gels as a function of CT content and for different freeze-thaw times, combining Small Angle X-Ray Scattering (SAXS), Scanning Electron Microscopy (SEM), and confocal microscopy. The nanoscale analysis obtained from SAXS shows that while the characteristic correlation length of the network is poorly affected by composition and freeze-thaw time, the characteristic size of heterogeneities associated with PVA crystallites decreases with CT content. SEM investigation evidences a transition to a more homogeneous network structure induced by the incorporation of CT that progressively builds a secondary network around the one formed by PVA. A detailed analysis of confocal microscopy image stacks allows to characterize the 3D porosity of the samples, revealing a significantly asymmetric shape of the pores. While the average volume of single pores increases with increasing CT content, the overall porosity remains almost unchanged as a result of the suppression of smaller pores in the PVA network with the progressive incorporation of the more homogeneous CT network. Increasing the freezing time in the FT cycles also results in a decrease of porosity, which can be associated with a growth in the crosslinking of the network due to PVA crystallization. The linear viscoelastic moduli measured by oscillatory rheology show a qualitatively comparable frequency-dependent response in all cases, with a moderate reduction with increasing CT content. This is attributed to changes in the structure of the strands of the PVA network.

Bayesian inference of the dense matter equation of state built upon covariant density functionals

A modified version of the density dependent covariant density functional model proposed in [T. Malik, M. Ferreira, B. K. Agrawal and C. Provid\^encia, ApJ 930, 17 (2022)] is employed in a Bayesian analysis to determine the equation of state (EOS) of dense matter with nucleonic degrees of freedom. Various constraints from nuclear physics and microscopic calculations of pure neutron matter (PNM) along with a lower bound on the maximum mass of neutron stars (NSs) are imposed on the EOS models to investigate the effectiveness of progressive incorporation of the constraints, their compatibility as well as correlations among parameters of nuclear matter and properties of NSs. Our results include the different roles played by pressure and energy per particle of PNM in constraining the isovector behavior of nuclear matter; tension with the values of Dirac effective mass extracted from spin-orbit splitting; correlations between the radius of the canonical mass NS and second and third order coefficients in the Taylor expansion of energy per particle as a function of density; correlation between the central pressure of the maximum mass configuration and Dirac effective mass of the nucleon at saturation. For some of our models the tail of the NS maximum mass reaches $2.7~\mathrm{M}_{\odot}$, which means that the secondary object in GW190814 could have been a NS.

Sustainable development in agriculture: Definition, barriers and consequences for Ukrainian agricultural producers

The paper aims to identify the views of Ukrainian agricultural producers and scientists on sustainable development in agriculture, its consequences and barriers faced by Ukrainian producers. Two surveys were done in 2021–2022. The exploratory (qualitative) study was conducted through a semi-structured interview carried out with 19 agricultural producers, who relate their businesses to sustainable practices and represent different Ukrainian regions. Based on the content analysis, we have found out how sustainable development is defined by actual producers operating in Ukrainian agriculture, barriers to the implementation of relevant practices, and consequences for the sector. Almost all statements of farmers are correlated with existing theoretical developments. In a second step, we conducted a survey with 142 scientists in the field of agriculture, who assessed on a 5-point scale whether certain sustainable practices, barriers and consequences are inherent to agriculture in Ukraine. The research has identified the dimensions of sustainable business development that suggest progressive changes and incorporation of a balanced approach to achieving goals into companies’ operating strategies. It means balancing growth in demand and limited consumption, high profits and necessary investments in sustainability (safety, working conditions), experimental science and farmers' on-the-ground knowledge.
