Understanding surface and bulk behaviour of surfactants using experimental and machine learning techniques
Creators: name: Seddon, Dale
Publisher: name: Imperial College London
Year: 2022

description: Surfactants are a unique category of amphiphilic molecules present all around us, in industrial and commercial products, as well as in the biological world. Surfactant molecules reside at the interface to reduce the free energy of the system; which consequentially reduces the surface tension (SFT) or interfacial tension (IFT). Despite surfactant formulations being ubiquitous in many areas, there still lacks a fundamental understanding of how these surfactant molecules and their interactions affect the macroscopic solution properties. A critical review on the use of microfluidics for interfacial tensiometry is conducted; the literature spanning approximately two decades is collated and categorised into eleven unique categories. The measurement principal for each category is described, and a comprehensive comparison of the categories given. The bulk behaviour of surfactant solutions is explored using SANS and rheology measurements; surfactant self-assembly is greatly influenced by environmental factors, such as surfactant concentration, the addition of any salt, and the temperature. The complete micellar phase map of sodium dodecyl sulphate (SDS) and sodium chloride (NaCl) is investigated at 25°C, and the low concentration SDS, high concentration NaCl region is further explored at higher temperatures up to 85°C to investigate the transition from elongated micelles to worm-like micelles. The mesoscopic micellar properties are then related to the macroscopic viscosity. The molecular properties and interactions of surfactants and surfactant mixtures are then explored using the macroscopic surface property of SFT. The surface and micellar interaction parameters are determined for surfactant mixtures of SDS and dodecyl dimethyl amine oxide (DDAO) with differing ratios to find the mixture with the most synergy. Machine learning techniques are implemented in conjunction with the Szyszkowski isotherm and critical micelle concentration to predict the complete SFT isotherm for hydrocarbon surfactants; the most influential descriptors for the SFT isotherm prediction are discussed in greater detail.

description: Dissipative dark matter, such as mirror dark matter and related hidden sector dark matter candidates, requires an energy source to stabilize dark matter halos in spiral galaxies. It has been proposed previously that supernovae could be the source of this energy. Recently, it has been argued that this mechanism might explain two galactic scaling relations inferred from observations of spiral galaxies. One of which is that $ρ_0 r_0$ is roughly constant, and another relates the galactic luminosity to $r_0$. [$ρ_0$ is the dark matter central density and $r_0$ is the core radius.] Here we derive equations for the heating of the halo via supernova energy, and the cooling of the halo via thermal bremsstrahlung. These equations are numerically solved to obtain constraints on the $ρ_0, \ r_0$ parameters appropriate for spiral galaxies. These constraints are in remarkable agreement with the aforementioned scaling relations.

description: We present DarkCLR, a novel framework for detecting semi-visible jets at the LHC. DarkCLR uses a self-supervised contrastive-learning approach to create observables that are approximately invariant under relevant transformations. We use background-enhanced data to create a sensitive representation and evaluate the representations using a CLR-inspired anomaly score and a normalized autoencoder as density estimators. Our results show a remarkable sensitivity for a wide range of semi-visible jets and are more robust than a supervised classifier trained on a specific signal.

description: Meeting Ann Ulanov in 2009 forever changed the course of my path. Though, another way of seeing it might be that my path was headed toward this particular course and toward meeting Dr. Ulanov as a mentor and guide who would help me discern that which was already discerning itself within. This is the mystery to which I have learned to respond and be curious about from the years of working with and learning from Dr. Ulanov. In particular she has helped me discern the mercurial path toward holding the tension between the two disparate and diverse fields of Hebrew Bible and Depth Psychology. She continually encourages not to dismiss one or the other, a temptation given the demands of each field and the very different aspects of the Self each field calls upon to wrestle with, engage, and work through. What follows is an example of the kind of work her mentorship has inspired over the years. Using the rich imagery of food Ulanov always encourages to seek out the intellectual protein for good nutrition and she herself delights in eating a rainbow of color for dinner. In light of her mentorship I have sought to engage that which is both personally sustaining and nutritious through its protein and vibrant colors and trust that, in turn, it is has meaning for others along the journey.

description: Using first-principles calculations, we show that the (001) surface of the ferromagnet La$_{1-x}$Sr$_{x}$MnO$_{3}$ under epitaxial compression favors antiferromagnetic ordering in the first few surface layers, coexisting with ferromagnetic bulk order. The change in magnetic order is accompanied by a marked surface-related spectral pseudogap, signaling a metal-insulator near-transition at the surface. All surfaces exhibit huge outward relaxations an rumpling of the MnO$_{2}$ and LaO surface planes, causing a distinct shift in work function. The AF phase is an extreme surface-assisted case of the combination of in-plane AF super-exchange and vertical FM double-exchange couplings that rules magnetism in manganites under in-plane compression.

description: The U.S. Bureau of Reclamation (Reclamation) reported a violation of the Archaeological Resources Protection Act (ARPA) in April 2003 when a petroglyph boulder was removed from Reclamation land. The boulder was located on a terrace edge overlooking the Agua Fria River north of Lake Pleasant, within archaeological site AZ T:4:157(ASM). A criminal investigation followed. The petroglyph boulder was recovered in September 2003. Subsequent to the investigation, Mr. Jon Czaplicki, Reclamation Archaeologist, requested that Archaeological Consulting Services, Ltd. (ACS) relocate the petroglyphs that were originally mapped when the site was recorded in 1996, remap their locations using a Global Positioning System (GPS) unit, and assess whether additional petroglyph boulders had been removed from AZ T:4:157(ASM) and/or adjacent site AZ T:4:156(ASM). The project also included relocation and mapping of the original datum stakes; mapping of natural and modern features such as terrace edges, drainages, and fences; and mapping of other selected archaeological features indicated as landmarks on CAD maps of the sites that were created in 1999. This letter report describes ACS' work to mitigate the damage to the site(s) and to protect the existing cultural resources. It also includes updated site maps.

description: The paeans we sing about Ann Ulanov on the occasion of her retirement after forty-seven years of teaching at Union Theological Seminary in New York are both plentiful and deserving. Those of us whose lives have been altered for the better, in big and small ways, by her writing, teaching, lecturing, and mentoring can easily testify to her extraordinary gift of being able to lucidly convey how the realities of the human psyche and the inner workings of the Divine Spirit interface with one another. Over the course of retirement celebration, portrait unveiling, and honorary festschrift, we laud her for the myriad contributions she has made on this front to the psychotherapeutic, religious, and academic communities of which she has been a part throughout her distinguished career. In the midst of such praise, we also readily find ourselves extolling her virtues of deep wisdom, sharp intellect, penetrative insight, and close attentiveness to even the smallest of details, which demonstrate her passionate love affair with life and soulful engagement with the wider world around her. As psychoanalyst, scholar, and teacher, she has long served, and continues to serve, as a guiding light for many who look to her in the hopes of finding and cultivating an inner light that is all their own.
Low-lying quasiparticle excitations in strongly-correlated superconductors: An ansatz from BCS quasiparticle excitations?

description: The question about the existence of Bogoliubov's quasiparticles in the BCS wave functions underneath Gutzwiller's projection is of importance to strongly correlated systems. We develop a method to examine the two-particle excitations of Gutzwiller-projected BCS wave functions by using the variational Monte Carlo approach. We find that the exact Gutzwiller-projected quasiparticle (GQP) dispersions are quantitatively reproduced by the Gutzwiller-projected Bogoliubov quasiparticles (GBQP) except the regions where d-wave Cooper pairing is strong. Since GQP still shows higher energy than GBQP near the antinodes, we believe GBQP provides a reasonable description to the low-energy excitations in strongly correlated superconducting systems. In addition, the intimate connection between Gutzwiller's projection and d-wave Cooper pairing may also imply that strong correlations play a significant role in the nodal-antinodal dichotomy seen by photoemission experiments in cuprates.

description: The elections of Ronald Reagan in the United States and Margaret Thatcher in England were important markers for the rise of a conceptual framework that continues to dominate economic policy today in the United States and around the world. Neoliberalism, defined by the anthropologist David Harvey as an attitude that advocates dismantling of the welfare state, deregulation, and weakening of trade unions in the name of a free market society (2005), has grown from a set of somewhat obscure economic principles into a hegemonic force. A far cry from its somewhat obscure origins, it is now incorporated into the “common-sense” of many of the world’s leaders and thinkers to the point that its basic assumptions are taken for granted and unquestioned.

description: In 2007, I opened a book that had been recommended to me called "Religion and the Spiritual in Carl Jung" by Ann Belford Ulanov and read the first sentence: “Jung looked for the Spirit in all things, even in neurosis or psychosis.”1 “What an extraordinary thought,” I said to myself with great curiosity, especially since a common predilection for religious folk is to quickly want to rid God from anything remotely dark or bleak such as we find in the experiences of neurosis and psychosis. I kept reading: numinous, meaning, archetype, psychoanalysis, object relations, Freud, primordial, psyche, the cross, Tillich, God. Though Jung and the basics of psychology were somewhat familiar to me, as was the exploration of religious categories even more so, I quickly noticed that I was not only responding to the ideas being put forth on the page, but I was connecting just as much to the way this person was synthesizing and expressing them. It was a fluid back and forth between psyche and spirit, the psychological and the religious, a testimony of faith in the capacities of both mind and God to show us the way forward, a perennial concern for the “so what?” factor of it all. I turned to the back cover: “Ann Belford Ulanov is the Christiane Brooks Johnson Professor of Psychiatry and Religion at Union Theological Seminary in New York. She has written extensively on Carl Jung and other issues that arise from the worlds of psychiatry and the spiritual.” From my religious and theological training, I knew well of Union Theological Seminary, but I was less familiar with Ann Ulanov. Who was this person and why had I not previously encountered her work in my graduate studies thus far? Despite this “extensive” writing on Jung and other subjects—a writing corpus which includes monographs, book chapters, and journal articles written over the course of such a distinguished career—why had this material on psyche and spirit not been introduced to me?

description: Studying under Ann Ulanov in the Department of Psychiatry and Religion at Union Theological Seminary was an opportunity to bring depth psychology and theology together in a way that fed my soul for eight years. Dr. Ulanov’s interdisciplinary methods as a teacher left room for the world of religion and the world of psychoanalysis to be explored and appreciated separately, and each for their own strengths. Yet there was always a powerful discovery to be made when psychological insight met theological wisdom. Her vast and still growing body of written work testifies to the many ways Dr. Ulanov has brought the two fields together. As a teacher, Ann has seemed to revel in the unique ways her students find and explore connections between the two disciplines. In my particular case, studies with Ann have nurtured a passion for conversation between psychoanalytic theory, Catholic faith, and the Hebrew Bible.

But the sheer number of people I know who have been deeply influenced by her, who have such glowing and remarkable things to say both about her work and her ability to make people feel heard, appreciated, and even loved (even alongside what has sometimes been characterized as a searing wit), reveals a person of irresistible creativity, intelligence, and personal dynamism. The essays found in this issue speak to all of these qualities of Dr. Ulanov, from the perspectives of generations of her students, colleagues, and students-become-colleagues.

There is Freud conversing with Tillich, here is Jung in an exchange with Simone Weil and Mondrian, over there Theresa of Avila and Winnicott, chatting with W.E.B. DuBois and Augustine. Now imagine that this whole party is for you, that every one of these people wants to interact with you, to know you, to dance with you. It’s exciting. It’s a whirlwind. Truth be told, it is sometimes a bit scary, and often quite serious, but mostly thrilling. At the end of the party you will be asked, “how have you changed, and how will you now change the world?” Now you have a picture of what it’s like to study with Ann Ulanov.

description: The performance of hybrid superconducting electronic coolers is usually limited by the accumulation of hot quasi-particles in the superconducting leads. This issue is all the more stringent in large-scale and high-power devices, as required by applications. Introducing a metallic drain connected to the superconducting electrodes via a fine-tuned tunnel barrier, we efficiently remove quasi-particles and obtain electronic cooling from 300 mK down to 130 mK with a 400 pW cooling power. A simple thermal model accounts for the experimental observations.

The effect of wheel unbalance on vehicle dynamics
Creators: name: Srinivasan, Prabandam
Publisher: name: California Institute of Technology
Year: 1956
Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: Some unbalance either inherent or induced is always to be expected in automobile wheels. It may be inherent due to imperfect balancing of the wheel or it may be induced by the uneven wear of the tires. While in motion this unbalance simultaneously sets up two vibrations in the wheel, one a linear vibration normal to the road and the other an angular vibration about the king pin. The frequency of these vibrations depends on the forward speed of the vehicle and when it coincides with the natural frequency of vibration of the wheels the well known phenomenon of resonance occurs.

The research reported in this thesis is a systematic investigation of this phenomenon in one front wheel of an automobile with the other three wheels in true balance. Known amounts of unbalance (both static and dynamic) were introduced into the left front wheel and road tests were conducted over a range of speeds covering resonance. Vibration pickups on the wheels recorded both vertical and angular displacement as a function of speed. Response curves have been plotted with the amount and type of unbalance as parameters. Also an attempt has been made to establish some bounds for the amount of unbalance that are noticeable to the passengers while traveling through the range of resonance.

description: The recently discovered low-density "super-Earths" Kepler-11b, Kepler-11f, Kepler-11d, Kepler-11e, and planets such as GJ 1214b represent most likely planets which are surrounded by dense H/He envelopes or contain deep H2O oceans also surrounded by dense hydrogen envelopes. Although these "super-Earths" are orbiting relatively close to their host stars, they have not lost their captured nebula-based hydrogen-rich or degassed volatile-rich steam protoatmospheres. Thus it is interesting to estimate the maximum possible amount of atmospheric hydrogen loss from a terrestrial planet orbiting within the habitable zone of late main sequence host stars. For studying the thermosphere structure and escape we apply a 1-D hydrodynamic upper atmosphere model which solves the equations of mass, momentum and energy conservation for a planet with the mass and size of the Earth and for a "super-Earth" with a size of 2 R_Earth and a mass of 10 M_Earth. We calculate volume heating rates by the stellar soft X-ray and EUV radiation and expansion of the upper atmosphere, its temperature, density and velocity structure and related thermal escape rates during planet's life time. Moreover, we investigate under which conditions both planets enter the blow-off escape regime and may therefore experience loss rates which are close to the energy-limited escape. Finally we discuss the results in the context of atmospheric evolution and implications for habitability of terrestrial planets in general.

MILQ optimizes the total execution time of a batch of circuits scheduled on multiple quantum devices. It leverages state-of-the-art circuit-cutting techniques to fit circuits onto the devices and schedules them based on a mixed-integer linear program. Our results show a total improvement of up to 26 % compared to a baseline approach.

description: The first day of classes for my Ph.D. in Psychiatry and Religion dawned spectacularly. It was a beautiful Tuesday morning, in early September. I packed my backpack with books for my first class with Dr. Ulanov. Having not studied with her since the first semester of doing an S.T.M. three years earlier, I was excited to begin academic studies with Dr. Ulanov again. I already had a full case load of psychotherapy clients at the Blanton-Peale Graduate Institute of Religion and Health, which was one of the clinical partners in this Ph.D. program at Union, but was looking forward to getting back to the demands, challenges, and delights of sitting in class and reading the way-too-long lists of books and articles Dr. Ulanov would assign. I left my apartment in Diocesan House at the Cathedral of St. John the Divine, where I was an Assistant Priest, grabbing my backpack, full of books for the first class—‘Aggression.’ Racing down the pathway to a staff meeting in Cathedral House, that would precede my 10 a.m. class, a colleague shared the news.
An investigation of forced flexural torsional oscillations of a wing and the phenomenon of flutter

Publisher: name: California Institute of Technology
Year: 1939
Subjects: Aeronautics

description: In this thesis the torsional-flexural response of a two-dimensional airfoil to forced oscillations of various frequencies and at various airspeeds is investigated.  The airfoil chosen has characteristics which are typical of modern American transport wings, and the speeds cover the range from zero airspeed up through the speeds for torsional-flexural flutter and torsional divergence.

In the latter part of this thesis, curves are plotted showing the effects which changes in the assumed wing parameters have on the torsional-flexural flutter speed and the torsional divergence speed.

description: We present a quark model calculation of the charmonium spectrum with self energy corrections due to the coupling to the meson-meson continuum. The bare masses used in the calculation are computed within the relativized quark model by Godfrey and Isgur. The strong decay widths of 3S, 2P, 1D and 2D $c \bar c$ states are also calculated, in order to set the values of the $^3P_0$ pair-creation model's parameters we use to compute the vertex functions of the loop integrals. Finally, the nature of the X(3872) resonance is analyzed and the main possibilities ($c \bar c$ state or $D \bar D^*$ molecule) are discussed. According to our results, the X(3872) is compatible with the meson $χ_{c1}(2P)$, with $J^{PC} = 1^{++}$, and is thus interpreted as a $c \bar c$ core plus higher Fock components due to the coupling to the meson-meson continuum. These $J^{PC} = 1^{++}$ quantum numbers are in agreement with the experimental results found by the LHCb collaboration. In our view, the X(3872)'s mass is lower than the quark model's predictions because of self energy shifts.

description: The U.S. Bureau of Reclamation (Reclamation) reported a violation of the Archaeological Resources Protection Act (ARPA) in April 2003 when a petroglyph boulder was removed from Reclamation land. The boulder was located on a terrace edge overlooking the Agua Fria River north of Lake Pleasant, within archaeological site AZ T:4:157(ASM). A criminal investigation followed. The petroglyph boulder was recovered in September 2003. Subsequent to the investigation, Mr. Jon Czaplicki, Reclamation Archaeologist, requested that Archaeological Consulting Services, Ltd. (ACS) relocate the petroglyphs that were originally mapped when the site was recorded in 1996, remap their locations using a Global Positioning System (GPS) unit, and assess whether additional petroglyph boulders had been removed from AZ T:4:157(ASM) and/or adjacent site AZ T:4:156(ASM). The project also included relocation and mapping of the original datum stakes; mapping of natural and modern features such as terrace edges, drainages, and fences; and mapping of other selected archaeological features indicated as landmarks on CAD maps of the sites that were created in 1999. This document is the photo log for a set of representative images taken during ACS' work at AZ T:4:157(ASM) and AZ T:4:156(ASM).

description: Traumatic brain injury (TBI) is a leading cause of death and disability worldwide. Due to major lacks in diagnostic and treatment measures, there is a need to identify biomarkers of TBI that could aid in improving TBI management. The main goal of this thesis was to characterise the metabolic profiles of rodent TBI to improve knowledge of the metabolic responses of TBI and treatment with xenon, ultimately aiding in biomarker identification. Using a rat model of blunt TBI and untargeted metabolomics, the thesis first looked at identifying plasma metabolic changes related to multiple TBI severity in the acute phase (15 minutes and 24 hours post-injury). Second, the thesis investigated the acute plasma metabolic responses of severe TBI and treatment with xenon gas, to identify biomarkers of severe TBI and xenon’s neuroprotective effect. To conclude, integration of metabolic profiles of severe TBI and TBI-related motor (i.e., gait) and histological outcomes (i.e., neuronal density) was conducted to identify the specificity of TBI metabolic responses with brain injury deficits. The thesis first identified an association between N-acetyl glycoproteins with TBI injury severity at 24 hours post-injury (pFDR = 0.024). Additionally, a plasma metabolic signature comprising of purine and pyrimidine metabolites were identified to be altered in severe TBI, particularly the alteration in plasma urate compared to sham animals (pFDR = 0.064). Multivariate modelling of the overall TBI-related metabolome also identified a trend in xenon’s ability to positively affect the TBI-related metabolome (p = 0.0082). Finally, an association between the identified metabolic profiles of severe TBI, neuronal density (pFDR < 0.1) and gait impairment (pFDR < 0.1) was identified. These findings, alongside the analytical pipeline applied, serve as the basis for future studies towards the identification of diagnostic, prognostic and therapeutic TBI biomarkers.
Nonlinear uncertainty propagation in space trajectories

description: This thesis addresses the problem of nonlinear uncertainty propagation in space trajectories. This problem can be specifically stated as follows: Given the initial orbital state of a spacecraft trajectory as random variables, what is the orbital state at some later time?

This problem is currently encountered by mission designers at institutions such as the Jet Propulsion Laboratory. Before an expensive space probe is irretrievably launched, extensive trajectory analyses are conducted to determine the amount of fuel needed to correct for trajectory errors. This involves propagation of uncertainties in the trajectories.

The current method for uncertainty propagation involves linearizing about the nominal trajectory to obtain a state transition matrix used to map the covariance matrix to a later orbital state. This method neglects nonlinear effects.

Two new algorithms were developed to account for nonlinear effects in the propagation of uncertainties in space trajectories. The first utilized simplifying assumptions to obtain analytic expressions for the probabilistic quantities describing the final orbital state. This algorithm provided good trend information but lacked precision. The second algorithm utilized Gaussian quadrature techniques to numerically compute the desired quantities. While requiring significant computational effort, this algorithm provided high precision.

Example trajectories were analyzed to compare the results from the new algorithms to those from the current method. Nonlinear effects were shown to influence both the mean and the variance results.
A new vertebrate fossil-bearing layer in the Rhætelv Formation (Kap Stewart Group) of central East Greenland: evidence of a Hettangian marine incursion into the continental Jameson Land Basin

description: The Kap Stewart Group (Rhaetian-Sinemurian, Triassic–Early Jurassic) of the Jameson Land Basin in central East Greenland has traditionally been regarded as a strictly continental unit with delta and perennial lake sediments. New finds of plesiosaur bone remain in a thin storm deposited sandstone bed in the middle part of the Rhætelv Formation of the Kap Stewart Group, however, indicates a likely period of marine influence. At the study area at the eastern margin of the basin, the Rhætelv Formation is 300-m thick and overlies unconformably the Norian Fleming Fjord Group. The bone-bearing sandstone occurs 190 m above the base of the group and is closely associated with black laminated mudstones; palynological investigation of three samples from these mudstones indicates that they are of a younger Hettangian age. The Hettangian was a relatively short stage (201.3–199.5 Ma) and elsewhere characterized by two episodes of sea-level highstands. Assuming that the marine incursion in the Jameson land Basin evidenced by the plesiosaur fossil remains took place during the youngest of these sea-level highstands, the bone-bearing bed of the Rhætelv Formation can be dated to 200 Ma and thereby gives the first numerical age constraint of this hitherto poorly dated succession.
Latitudinal land–sea distributions and global surface albedo since the Cretaceous

description: We estimate global surface albedo from the areal proportion of land to sea in climatically-significant latitudinal belts at ten million-year intervals for the Late Cretaceous and Cenozoic (120 million years ago to Present) using modern plate tectonic reconstructions and a composite apparent polar path designed to minimize known biases in the determination of paleolatitude. We find that global surface albedo stayed almost constant until it shifted 30% higher to the modern value of around 0.15 with the inception of the Late Cenozoic Ice Age 34 million years ago, reflecting polar ice-albedo amplification of global cooling resulting from the reduction of greenhouse gases below a critical threshold, most probably as the culmination of enhanced CO2 weathering consumption of continental mafic rocks in the tropical humid belt. The contribution from cloud cover toward a planetary albedo is unclear in the absence of measurable proxies but might eventually be gauged from the role cloudiness evidently plays in maintaining radiative balance with the increasing land bias between northern and southern hemispheres over the Cenozoic.

description: The stacking of intrinsically magnetic van der Waals materials provides a fertile platform to explore tunable transport effects of magnons, presenting significant prospects for spintronic applications. The possibility of having topologically nontrivial magnons in these systems can further expand the scope of exploration. In this work, we consider a bilayer system with intralayer ferromagnetic exchange and a weak interlayer antiferromagnetic exchange, and study the topological magnon-polaron excitations induced by magnetoelastic couplings. Under an applied magnetic field, the system features a metamagnetic transition, where the magnetic ground state changes from antiparallel layers to parallel. We show that the metamagnetic transition is accompanied by a transition of the topological structure of the magnon polarons, which results in discernible changes in the topology induced transport effects. The magnetic-field dependence of the thermal Hall conductivity and spin Nernst coefficient is analyzed with linear response theories.

description: Standard methods, standard test conditions and the use of good sensory practices are key elements of sensory testing. However, while compliance assessment by trained and expert assessors is well developed, few information is available on testing consumer consistency. Therefore, we aim to answer the following research questions: What type of metrics can be used to characterise (in)consistent evaluation? How to rank assessors and attributes' evaluations based on (in)consistency? Who can be considered an (in)consistent assessor? What is the difference between consistent and inconsistent assessors' evaluations and use of scale? What is the impact of consistent and inconsistent assessors' evaluations on the overall liking estimate? The proposed detection of (in)consistency requires evaluations on two connected scales. We reveal how assessors and attributes can be ranked according to the level of inconsistency, as well as how inconsistent assessors can be identified. The suggested approach is illustrated by data from sensory tests of biscuits enriched with three pollens at different levels. Future consumer tests are recommended to account for possible inconsistent evaluations.
