Detuned surface plasmon resonance scattering of gold nanorods for continuous wave multilayered optical recording and readout

description: In a multilayered structure of absorptive optical recording media, continuous-wave laser operation is highly disadvantageous due to heavy beam extinction. For a gold nanorod based recording medium, the narrow surface plasmon resonance (SPR) profile of gold nanorods enables the variation of extinction through mulilayers by a simple detuning of the readout wavelength from the SPR peak. The level of signal extinction through the layers can then be greatly reduced, resulting more efficient readout at deeper layers. The scattering signal strength may be decreased at the detuned wavelength, but balancing these two factors results an optimal scattering peak wavelength that is specific to each layer. In this paper, we propose to use detuned SPR scattering from gold nanorods as a new mechanism for continuous-wave readout scheme on gold nanorod based multilayered optical storage. Using this detuned scattering method, readout using continuous-wave laser is demonstrated on a 16 layer optical recording medium doped with heavily distributed, randomly oriented gold nanorods. Compared to SPR on-resonant readout, this method reduced the required readout power more than one order of magnitude, with only 60 nm detuning from SPR peak. The proposed method will be highly beneficial to multilayered optical storage applications as well as applications using a continuous medium doped heavily with plasmonic nanoparticles.
Sistemi Combinatori. L'ordine nel comportamento collettivo

description: Questo studio si propone di presentare la Combinatory Systems Theory, una semplice teoria che è in grado di descrivere, interpretare e spiegare molti fenomeni collettivi e loro effetti osservabili. La Teoria dei Sistemi Combinatori è stata recentemente formalizzata dal mio volume Combinatory Systems Theory, edito da Sprin- ger nel 2017. Ad esso mi sono in parte ispirato nello svolgimento di questo paper. Un “Sistema Combinatorio” è una "collettività" (pluralità, popolazione, specie, gruppo ecc) di agenti relativamente simili (uomini, animali, batteri e così via) che producono micro comportamenti e micro effetti relativamente analoghi (dinamiche dei loro micro-stati) osservabili (o definibili). Considerati insieme, i micro comportamenti /effetti producono un macro comportamento emergente (dinamica del macro-stato collettivo), che non è incluso in anticipo nel pro- gramma operativo del comportamento degli agenti, ma è invece attribuibile alla "collettività" nel suo comples- so, considerata come un sistema unitario. Il macro comportamento collettivo, a sua volta, condiziona o dirige i successivi micro comportamenti degli agenti. Questo rapporto reciproco agenti-collettività è definito “micro- macro feedback” e rappresenta una condizione necessaria e sufficiente per l’esistenza di un sistema combinato- rio in quanto garantisce il mantenimento nel tempo del macro comportamento del sistema e aggiorna costante- mente i micro comportamenti; quando il sistema si avvia "per caso", "di necessità esso sviluppa e mantiene nel tempo le sue dinamiche, come se una "mano invisibile", una “Autorità Suprema” regolasse tali dinamiche e producesse gli effetti osservabili e i modelli di comportamento. Di fatto, i Sistemi Combinatori sono in grado di produrre molti fenomeni osservabili quattro dei quali sono: l'accumulo di oggetti, la diffusione oggetti, caratteri e funzionalità, il perseguimento o superamento di un limite e il raggiungimento ed il mantenimento di un ordine tra i micro comportamenti degli agenti. Un quinto rilevante effetto, che comprende gli altri, è la dinamica inter- dipendente tra il miglioramento individuale perseguito dagli agenti e il progresso collettivo nello stato generale di una collettività (definito in modi opportuni).

description: Excerpts from the report: The Basin has a total area of 3,980 square miles--2,547,000 acres--and includes all or parts of 15 counties. The average rainfall is 39 inches and the growing season is about 200 days. Elevations range from 400 to 1,400 feet mean sea level. The Meramec River is a tributary of the Mississippi River; the confluence is about 11 miles south of the city limits of St. Louis. Woodlands make up about three-fifths of the Basin. About one-fifth of the land is cropland, one-fifth is in pasture or other uses. Almost 15 percent, including Clark National Forest, State forests, parks, recreation areas, and wildlife areas, is in public ownership. This report by the U.S. Department of Agriculture is part of a comprehensive plan for development of the water and related-land resources in the Meramec River Basin in Missouri. Included in this report are the analyses of current and future water-management needs affecting erosion control, flood prevention, water supply, fish and wildlife, and outdoor recreation. The relationship of agricultural water problems and the need for economic development was also appraised. An inventory of the land resources for present and potential use is included. This report considers the immediate and projected needs for land and water resources and also the needs of food and fiber for the population within and surrounding the Basin. The use of natural resources by agricultural and forest industries, and their contribution to the present and prospective economy, is included.

description: Aluminium honeycomb is a type of cellular material which has high strength to weigh ratio and is a good energy absorber. They are used as structural components in various engineering applications. Comprehensive study has been conducted on the compressive behavior of aluminium honeycombs. However, the research of aluminium honeycombs subjected to other type of loading, such as indentation, is still limited. In this paper, quasi-static and dynamic indentation tests were conducted to study the deformation and energy absorption of three types of HEXCELL (R) aluminium honeycombs with different cell sizes and cell wall thicknesses. Quasi-static tests were conducted by using a universal MTS machine at velocities of 0.05 mm/s, 0.5 mm/s and 5 mm/s, respectively. Dynamic tests were conducted by using a high speed INSTRON machine at a velocity of 5 m/s. Force-displacement curves were plotted in which the total energy absorbed was calculated. The deformation of aluminium honeycombs in indentation tests includes the compression of honeycomb cells under the indenter and tearing of honeycomb cell walls along the indenter edges. The energy dissipated in compression and tearing were calculated and discussed. The effects of cell size, cell wall thickness and loading velocity or strain rate on the plateau stress and energy absorption were analyzed.

During transport to critical care centres, neonatal patients can be exposed to elevated levels of vibration which may pose a risk to the patients’ health. In Ontario, a standardized Neonatal Patient Transport System (NPTS) has been implemented in ground and air ambulances, and studies to characterize the vibration environment within these vehicles are underway. The development of a dynamic model of the NPTS is intended to support the study of emergency vehicle vibration environments and strategies to mitigate vibration amplification. This paper outlines the derivations of equations of motion for a planar model of the NPTS. This derivation uses the Lagrangian approach to develop equations governing motion in the pitch plane. Stiffness and damping coefficients were optimized to drive the frequency response of the developed dynamic model towards data recorded during on-road testing. Future development of the model will involve deriving the equations for the roll plane, and further optimization of stiffness and damping parameters to ensure they adequately represent the response for various transport conditions.

description: Lasioglossum (Dialictus) sheffieldi Gibbs 2010 (perdifficile group) (New state record)
County records: Alger.
Notes. Lasioglossum sheffieldi is a sand dune specialist, originally described from coastal areas of the Canadian Maritime Provinces and the western bank of the St. Lawrence River in Quebec (Gibbs 2010b). Two additional specimens, one from a Manitoba dune system and the other from the west coast of Lake Michigan in Wisconsin, were examined but not included as paratypes due to their disjunct localities (Gibbs 2010b). A long series of males and females were recently examined from Pictured Rocks National Lakeshore, which fills an important gap in the known distribution of this species, and points to the likelihood of additional unknown localities in other dune and lakeshore habitats, which may connect the inland populations to the populations on the Atlantic Coast.

description: The Internet has the potential to be an effective medium for delivering health care knowledge to consumers. While computer usability research makes recommendations about how to present Web-based information generally, there remains no clear guidance on how to present specific forms of health care research evidence online in a way that facilitates understanding and good health care decision making. The two goals of this study were to describe the Cochrane Musculoskeletal Group's (CMSG's) process for developing online patient-focused summaries of systematic reviews and to evaluate the impressions of these summaries formed by users. A process for summarizing the results of systematic reviews via consumer summaries has evolved over 15 years. An evaluation of this approach took the form of Internet surveys on the Arthritis Society of Canada website and surveys of members of the Canadian Arthritis Patient Alliance (CAPA). Respondents provided information on background, relationship to the decision, their satisfaction with and preparation for decision making, and suggestions for improvements to the summaries. Survey data were collected between August 1, 2005, and February 28, 2006. A total of 261 respondents completed the survey. The majority (226/261 or 87%) of respondents reported having an arthritis-related condition. The consumer summary approach was generally reviewed favorably by respondents, with most agreeing that the summary provided appropriate information (177/261 or 68%), would be useful to others (160/261 or 61%), was well laid out (159/261 or 61%), was easy to learn from (157/261 or 60%), and was useful to the reader (153/261 or 59%). Areas of potential improvement were indicated by relatively fewer respondents agreeing that they could easily find all the information they wanted (118/261 or 45%), by a substantial proportion being unable to judge whether the providers of the information are reliable (80/261 or 31%), and by a similar proportion being unable to determine whether the information presented was the best available (68/261 or 26%). The CMSG has developed an approach to summarizing the results of often-technical systematic reviews into public-friendly consumer summaries. Our online survey showed that this approach was generally well liked but identified specific areas for improvement. Feedback from this survey will help to reshape and improve the current template for consumer summaries used by the CMSG.

Pulses of ocean primary productivity during the fall season are frequent in the mid-latitudes when ocean cooling and wind-driven turbulence erode the surface stratification and allow the injection of nutrients into the euphotic zone. This  phenomenon is often referred to as a phytoplankton fall bloom, and can play an essential role in the survival of marine species during winter. In Hudson Bay, we found that pelagic fall blooms are triggered when the convective mixing, forced mainly by atmospheric cooling and to a lesser extent to wind-driven turbulence, expands the mixed layer, ventilates the pycnocline, and likely erodes the nitracline. Ocean color observations were used to assess the seasonal variability of phytoplankton photoacclimation state from the ratio of phytoplankton carbon (Cphy) to chlorophyll-a concentration ([chla]). Cphy was estimated using the satellite-derived particulate backscattering coefficient (bbp)aftersubtractionofthe non-algal backscattering background.We found a systematic increase in Cphy and Cphy:[chla] from mid-summer to fall season indicating that fall blooms are potentially productive in term of organic carbon fixation.

Composite materials are widely used in the defense and aerospace industry because of their light weight and high strength properties. Ultra-high molecular weight polyethylene (UHMW-PE) is commonly used in the design of various types of armor from vehicle applications to personal protective clothing. Understanding the ballistic characteristics of this material is essential to designing safe armor systems. A numerical analysis of the ballistic impact of fragment simulating projectiles (FSPs) on UHMW-PE is presented in this paper using the IMPETUS Afea Solver Suite. The material model for UHMW-PE under high strain rates has not been discussed in the available literature. In this study, the IMPETUS fabric material model is used to define the UHMW-PE properties, along with a cohesive failure criteria to capture delamination. Several simulations were conducted with projectile impact velocities ranging from 464 m/sec to 1058 m/sec, and thickness variations of UHMW-PE of 10 mm, 20 mm, and 36.2 mm. The numerical results, which include ballistic limit and residual velocity, are verified against experimental data present in the literature. The collective findings can be applied to future work to accelerate the design process by minimizing the time and cost of performing experiments.

description: The epidermal growth factor receptor (EGFR) kinase is generally considered to be activated by either ligand-induced dimerisation or a ligand-induced conformational change within pre-formed dimers. Ligand-induced higher-order EGFR oligomerisation or clustering has been reported but it is not clear how EGFR oligomers, as distinct from EGFR dimers, influence signaling outputs. To address this question, we combined measures of receptor clustering (microscopy; image correlation spectroscopy) and phosphorylation (Western blots) with modelling of mass-action chemical kinetics. A stable BaF/3 cell-line that contains a high proportion (>90%) of inactive dimers of EGFR-eGFP but no secreted ligand and no other detectable ErbB receptors was used as the model cell system. EGF at concentrations of greater than 1 nM was found to cluster EGFR-eGFP dimers into higher-order complexes and cause parallel increases in EGFR phosphorylation. The kinetics of EGFR clustering and phosphorylation were both rapid, plateauing within 2 minutes after stimulation with 30 nM EGF. A rule-based model was formulated to interpret the data. This model took into account ligand binding, ligand-induced conformational changes in the cytosolic tail, monomer-dimer-trimer-tetramer transitions via ectodomain- and kinase-mediated interactions, and phosphorylation. The model predicts that cyclic EGFR tetramers are the predominant phosphorylated species, in which activated receptor dimers adopt a cyclic side-by-side orientation, and that receptor kinase activation is stabilised by the intramolecular interactions responsible for cyclic tetramerization.

The oceanic heat available in Greenland’s troughs is dependent on the geographic location of the trough, the water origin, and how the water is impacted by local processes along the pathway to the trough. This study investigates the spatial pattern and quantity of the warm water (with a temperature greater −1.5◦C) brought to the shelf and into the troughs abutting the Greenland Ice Sheet (GrIS). An increase in ocean heat in these troughs may drive a retreat of the GrIS. Warm water that is exchanged from the trough into the fjord may influence the melt on the marine-terminating glaciers. Several regional ocean model experiments were used to study regional differences in heat transport through troughs. Results showed that warm water extends north into Baffin Bay, reaching as far north as the Melville Bay troughs. Melville Bay troughs experienced warming following 2009. From 2004 to 2006, model experiments captured an increase in onshore heat flux in the Disko Bay trough, coinciding with the timing of the disintegration of Jakobshavn Isbrae’s floating tongue and observed ocean heat increase in Disko Bay. The seasonality of the maximum onshore heat flux differs due to distance away from the Irminger Sea. Ocean temperatures near the northwestern coast and southeastern coast respond differently to changes in meltwater from Greenland and high-frequency atmospheric phenomena. With a doubling of the GrIS meltwater, Baffin Bay troughs transported ∼ 20 % more heat towards the coast. Fewer storms resulted in a doubling of onshore heat through Helheim Glacier’s trough. These results demonstrate the regional variability of onshore heat transport through troughs and its potential implications to the GrIS.

description: Excerpts from the report: The Tombigbee River Basin is part of a sub-region of the South Atlantic-Gulf Region. The basin is located in Western Alabama and Northeastern Mississippi. It comprises all or part of 16 counties in Alabama and 19 counties in Mississippi. The boundary encompasses 8.8 million acres of land and water, with 4.9 million acres in Alabama and 3.9 million acres in Mississippi. It is approximately 85 miles wide and 260 miles long. The basin consists of the drainage area of the Tombigbee River above the confluence with the Alabama River, except for the drainage area of the Black Warrior River that flows into the Tombigbee River near Demopolis, Alabama. The eastern boundary is the divide of the Alabama and Black Warrior Rivers. The Tennessee and Hatchie River Systems make up the northern boundary. The western boundary consists of the divides of the Tallahatchie, Yalobusha, Big Black, Pearl, Chickasawhay, and Escatawpa Rivers. The purpose of the study was to formulate alternative plans and suggest an alternative for use in facilitating the coordinated and orderly conservation, development, utilization, and management of the water and related land resources of the basin. Achievement of this purpose required an assessment of the water and related land resource problems, needs, and development potentials of the basin.

description: We previously reported observations of quasar spectra from the Keck telescope suggesting a smaller value of the fine structure constant, alpha, at high redshift. A new sample of 153 measurements from the ESO Very Large Telescope (VLT), probing a different direction in the universe, also depends on redshift, but in the opposite sense, that is, alpha appears on average to be larger in the past. The combined dataset is well represented by a spatial dipole, significant at the 4.1 sigma level, in the direction right ascension 17.3 +/- 0.6 hours, declination -61 +/- 9 degrees. A detailed analysis for systematics, using observations duplicated at both telescopes, reveals none which are likely to emulate this result.

description: By comparing the widths of absorption lines from O i, Si ii and Fe ii in the redshift zabs= 2.076 single-component damped Lyα system in the spectrum of Q2206−199 we establish that these absorption lines arise in warm neutral medium (WNM) gas at ∼12 000 ± 3000 K. This is consistent with thermal equilibrium model estimates of ∼8000 K for the WNM in galaxies, but not with the presence of a significant cold component. It is also consistent with, but not required by, the absence of C ii fine structure absorption in this system. Some possible implications concerning abundance estimates in narrow-line WNM absorbers are discussed.
Atomistic measurement of the effect of interface tuning on the toughening and failure mechanisms of polypropylene nanocomposites toughened with nanofibrillated rubber

In the present study, we investigate the roles of interface and interfiber interactions on the toughening and failure mechanisms of nanofibrillated rubber-toughened thermoplastic-based nanocomposites. Emphasis is placed on establishing a comprehensive theoretical and atomistic descriptions of the nanocomposite systems subjected to pull-out and uniaxial tests. Using the framework of molecular dynamics, the annealed melt-drawn nanofibers were spontaneously formed via the proposed four-step methodology. The generated nanofibers were then crosslinked using the proposed robust topology-matching algorithm, through which the chemical reactions arising in the crosslinking were closely assimilated. The interfiber interactions were also examined with respect to separation distances and nanofiber radius via nanofiber pair atomistic scheme and the obtained results were subsequently incorporated into the pull-out and uniaxial tests simulations. The results indicate that the compatibilizer grafting results in enhanced interfacial shear strength by introducing extra chemical interactions at the interface. In particular, it was found that the compatibilizer restricts the formation and coalescence of nanovoids, resulting in enhanced toughening effects. Together, we have shown that the presence of a small amount of well-dispersed rubber nanofibrillar network whose surfaces are grafted with maleic anhydride compatibilizer can dramatically increase the toughness and alter the failure mechanisms of the nanocomposites without deteriorating stiffness which is also consistent with the recent experimental observations. The interfacial failure mechanism was also investigated by monitoring of the changes in the atomic concentration profiles, mean square displacement and fractional free volume.

Year: 2018

Sea ice thickness evolution within the Canadian Arctic Archipelago (CAA) is of great interest to science, as well as local communities and their economy. In this study, based on the NEMO numerical framework including the LIM2 sea ice module, simulations at both 1/4 and 1/12◦ horizontal resolution were conducted from 2002 to 2016. The model captures well the general spatial distribution of ice thickness in the CAA region, with very thick sea ice (∼ 4 m and thicker) in the northern CAA, thick sea ice (2.5 to 3 m) in the west-central Parry Channel and M’Clintock Channel, and thin (< 2 m) ice (in winter months) on the east side of CAA (e.g., eastern Parry Channel, Baffin Island coast) and in the channels in southern areas. Even though the configurations still have resolution limitations in resolving the exact observation sites, simulated ice thickness compares reasonably (seasonal cycle and amplitudes) with weekly Environment and Climate Change Canada (ECCC) New Ice Thickness Program data at first-year landfast ice sites except at the northern sites with high concentration of old ice. At 1/4 to

1/12◦ scale, model resolution does not play a significant role in the sea ice simulation except to improve local dynamics

because of better coastline representation. Sea ice growth is decomposed into thermodynamic and dynamic (including all

non-thermodynamic processes in the model) contributions to study the ice thickness evolution. Relatively smaller thermodynamic contribution to ice growth between December and the following April is found in the thick and very thick ice

regions, with larger contributions in the thin ice-covered region. No significant trend in winter maximum ice volume is found in the northern CAA and Baffin Bay while a decline (r2 ≈ 0.6, p < 0.01) is simulated in Parry Channel region. The two main contributors (thermodynamic growth and lateral transport) have high interannual variabilities which largely balance each other, so that maximum ice volume can vary interannually by ±12 % in the northern CAA, ±15 % in Parry Channel, and ±9 % in Baffin Bay. Further quantitative evaluation is required.

description: Aims. We aim at analysing systematically the distribution and physical properties of neutral and mildly ionised gas in the Milky Way halo, based on a large absorption-selected data set. Methods. Multi-wavelength studies were performed combining optical absorption line data of Ca ii and Na i with follow-up H i 21-cm emission line observations along 408 sight lines towards low- and high-redshift QSOs. We made use of archival optical spectra obtained with UVES/VLT. H i data were extracted from the Effelsberg-Bonn H i survey and the Galactic All-Sky survey. For selected sight lines we obtained deeper follow-up observations using the Effelsberg 100-m telescope. Results. Ca ii (Na i) halo absorbers at intermediate and high radial velocities are present in 40–55% (20–35%) of the sightlines, depending on the column density threshold chosen. Many halo absorbers show multi-component absorption lines, indicating the presence of sub-structure. In 65% of the cases, absorption is associated with H i 21-cm emission. The Ca ii (Na i) column density distribution function follows a power-law with a slope of β ≈ −2.2 (−1.4). Conclusions. Our absorption-selected survey confirms our previous results that the Milky Way halo is filled with a large number of neutral gas structures whose high column density tail represents the population of common H i high- and intermediate-velocity clouds seen in 21-cm observations. We find that Na i/Ca ii column density ratios in the halo absorbers are typically smaller than those in the Milky Way disc, in the gas in the Magellanic Clouds, and in damped Lyman α systems. The small ratios (prominent in particular in high-velocity components) indicate a lower level of Ca depletion onto dust grains in Milky Way halo absorbers compared to gas in discs and inner regions of galaxies.

description: Lasioglossum (Dialictus) subversans (Mitchell 1960)
Dialictus subversans Mitchell, 1960: 419. (Michigan holotype)
Holotype. ♀ USA: Michigan: Otsego Co.: 26.iv.1944, R.R. Dreisbach (NMNH).
County records: Dickinson, Ontonagon, Otsego, Van Buren.
Notes. Lasioglossum subversans was poorly documented in the literature until revisionary studies by Gibbs (2010 b, 2011) who treated it as synonymous with Dialictus perpunctatulus Knerer & Atwood. Lasioglossum subversans appears to have a northern distribution, extending across Canada but only reaching south into the USA in northern Michigan and Maine.

description: Test case generation is a vital procedure in the engineering of test harnesses. In particular, the choice relation framework and the category-partition method play an important role, by requiring software testers to identify categories (intuitively equivalent to input parameters or environment conditions) and choices (intuitively equivalent to ranges of values) from a specification and to systematically work on the identified choices to generate test cases. Other specification-based test case generation methods (such as the classification-tree method, cause-effect graphing, and combinatorial testing) also have similar requirements, although different terminology such as classifications and classes is used in place of categories and choices. For a large and complex specification that contains many specification components, categories and choices may be identified separately from various kinds of components. We call this practice an incremental identification approach. In this paper, we discuss our study involving 16 experienced software practitioners and three commercial specifications. Our objectives are to determine, from the opinions of the practitioners, (a) the popularity of an incremental identification approach, (b) the usefulness of identifying categories and choices from various kinds of specification components, and (c) possible ways to improve the effectiveness of the identification process.

description: Test case selection is a prime process in the engineering of test harnesses. In particular, test case diversity is an important concept. In order to achieve an even spread of test cases across the input domain, Adaptive Random Testing (ART) was proposed such that the history of previously executed test cases are taken into consideration when selecting the next test case. This was achieved through various means such as best candidate selection, exclusion, partitioning, and diversity metrics. Empirical studies showed that ART algorithms make good use of the concept of even spreading and achieve 40 to 50% improvement in test effectiveness over random testing in revealing the first failure, which is close to the theoretical limit. However, the computational complexity of ART algorithms may be quadratic or higher, and hence efficiency is an issue when a large number of previously executed test cases are involved. This paper proposes an innovative divide-and-conquer approach to improve the efficiency of ART algorithms while maintaining their performance in effectiveness. Simulation studies have been conducted to gauge its efficiency against two most commonly used ART algorithms, namely, fixed size candidate set and restricted random testing. Initial experimental results show that the divide-and-conquer technique can provide much better efficiency while maintaining similar, or even better, effectiveness.

description: The extended Navier-Stokes theory accounts for the coupling between the translational and rotational molecular degrees of freedom. In this paper, we generalize this theory to non-zero frequencies and wavevectors, which enables a new study of spatio-temporal correlation phenomena present in molecular fluids. To discuss these phenomena in detail, molecular dynamics simulations of molecular chlorine are performed for three different state points. In general, the theory captures the behavior for small wavevector and frequencies as expected. For example, in the hydrodynamic regime and for molecular fluids with small moment of inertia like chlorine, the theory predicts that the longitudinal and transverse intrinsic angular velocity correlation functions are almost identical, which is also seen in the molecular dynamics simulations. However, the theory fails at large wavevector and frequencies. To account for the correlations at these scales, we derive a phenomenological expression for the frequency dependent rotational viscosity and wavevector and frequency dependent longitudinal spin viscosity. From this we observe a significant coupling enhancement between the molecular angular velocity and translational velocity for large frequencies in the gas phase; this is not observed for the supercritical fluid and liquid state points.

description: Abstract

Umar Kayam's novel Para Priyayi explores ethics education by ngenger ways in Javanese tradition. The ngenger culture is an effort by the poor to gain the greatest and most equitable access to education. This novel show that the ngenger culture is used to gain access to formal education and get informal education in the Javanese tradition. Ngenger ways that to do by the actors would instill ethical educational values that help people achieve life goals and achieve success. The ngenger culture emphasizes ethics education, which is internalized through habituation, teaching, behavior, and outward and inner experiences.
