Subjects: subject: 530

description: We investigate the effect of quenched bond disorder on the anisotropic antiferromagnetic spin-1/2 (XXZ) chain as a model for disorder-induced quantum phase transitions. We find nonuniversal behavior of the average correlation functions for weak disorder, followed by a quantum phase transition into a strongly disordered phase with only short-range xy correlations. We find no evidence for the universal strong-disorder fixed point predicted by the real-space renormalization group, suggesting a qualitatively different view of the relationship between quantum fluctuations and disorder.

description: We report on the ion beam fabrication of all-carbon multi electrode arrays (MEAs) based on 16 graphitic micro-channels embedded in single-crystal diamond (SCD) substrates. The fabricated SCD-MEAs are systematically employed for the in vitro simultaneous amperometric detection of the secretory activity from populations of chromaffin cells, demonstrating a new sensing approach with respect to standard techniques. The biochemical stability and biocompatibility of the SCD-based device combined with the parallel recording of multi-electrodes array allow: i) a significant time saving in data collection during drug screening and/or pharmacological tests over a large number of cells, ii) the possibility of comparing altered cell functionality among cell populations, and iii) the repeatition of acquisition runs over many cycles with a fully non-toxic and chemically robust bio-sensitive substrate.

description: Pluripotent embryonic stem cells have a unique and characteristic epigenetic profile, which is critical for differentiation to all embryonic germ lineages. When stem cells exit the pluripotent state and commit to lineage-specific identities during the process of gastrulation in early embryogenesis, extensive epigenetic remodelling mediates both the switch in cellular programme and the loss of potential to adopt alternative lineage programmes. However, it remains to be understood how the stem cell epigenetic profile encodes pluripotency, or how dynamic epigenetic regulation helps to direct cell fate specification. Recent advances in stem cell culture techniques, cellular reprogramming, and single-cell technologies that can quantitatively profile epigenetic marks have led to significant insights into these questions, which are important for understanding both embryonic development and cell fate engineering. This review provides an overview of key concepts and highlights exciting new advances in the field.

description: In the course of the past several years holography has emerged as an ab initio tool in exploring strongly-time-dependent phenomena in gauge theories. These lecture notes overview recent developments in this area driven by phenomenological questions concerning applicability of hydrodynamics (hydrodynamization) under extreme conditions occurring in ultrarelativistic heavy-ion collisions at RHIC and LHC. The topics include hydrodynamization time scale, holographic collisions, as well as hydrodynamization from the point of view of the asymptotic character of the hydrodynamic gradient expansion. The emphasis is put on concepts rather than calculational techniques and a particular attention is devoted to present these developments in the context of the most recent advances and some of the open problems.

description: In this work we study the issue of gauge anomalies in Lorentz-violating QED. To do so, we opt to use the Becchi-Rouet-Stora-Tyutin formalism within the algebraic renormalization approach, reducing our study to a cohomology problem. Since this approach is independent of the renormalization scheme, the results obtained here are expected to be general. We find that the Lorentz-violating QED is free of gauge anomalies to all orders in perturbation theory.

description: Kidney cancer is a severe disease which can be treated non-invasively using high-intensity focused ultrasound (HIFU) therapy. However, tissue in front of the transducer and the deep location of kidney can cause significant losses to the efficiency of the treatment. The effect of attenuation, refraction and reflection due to different tissue types on HIFU therapy of the kidney was studied using a nonlinear ultrasound simulation model. The geometry of the tissue was derived from a computed tomography (CT) dataset of a patient which had been segmented for water, bone, soft tissue, fat and kidney. The combined effect of inhomogeneous attenuation and sound-speed was found to result in an 11.0 dB drop in spatial peak-temporal average (SPTA) intensity in the kidney compared to pure water. The simulation without refraction effects showed a 6.3 dB decrease indicating that both attenuation and refraction contribute to the loss in focal intensity. The losses due to reflections at soft tissue interfaces were less than 0.1 dB. Focal point shifting due to refraction effects resulted in -1.3, 2.6 and 1.3 mm displacements in x-, y- and z-directions respectively. Furthermore, focal point splitting into several smaller subvolumes was observed. The total volume of the secondary focal points was approximately 46% of the largest primary focal point. This could potentially lead to undesired heating outside the target location and longer therapy times.

description: Using deuteron NMR, we have studied molecular reorientation rates and rate exchange processes in supercooled ortho-terphenyl. We monitor the re-equilibration of differently selected subensembles through four-time stimulated echo experiments. A comparison of the two-time with the four-time echoes suggests that the characteristic time scales for reorientation and dynamical exchange are relatively similar. The four-time correlation functions were described using various multi-state rate exchange models.

Corrosion is one of the most important issues in the aerospace industry and the production of the components of an aircraft. Therefore, certain components of an aircraft are coated in order to provide adequate corrosion protection in service. One of those components is the landing gear of an  aircraft which can be protected using either Cadmium or Zn- Ni electroplating. However, one of the major issues associated  with this process is the possibility of hydrogen embrittlement (HE) of the base metal. Zn-Ni brush plating is commonly used in aerospace industry for on-site repair of localized coating damage. Thus, in order to evaluate the HE of base metal (SAE 4340 steel) after Zn-Ni brush plating, a 200-hour sustained load test as per ASTM F519 of plated notched specimens was conducted. The results indicate considerable hydrogen embrittlement in the case of non-baked samples while baking even at a temperature of 100°C, which is a significantly lower temperature than the industry standard of 190°C, alleviated the embrittlement. Sand blasting before plating was also found to have a considerable influence in the results of the embrittlement test.

description: We consider the leading and subleading UV divergences for the four-point on-shell scattering amplitudes in D=6,8,10 supersymmetric Yang-Mills theories in the planar limit. These theories belong to the class of maximally supersymmetric gauge theories and presumably possess distinguished properties beyond perturbation theory. In the previous works, we obtained the recursive relations that allow one to get the leading and subleading divergences in all loops in a pure algebraic way. The all loop summation of the leading divergences is performed with the help of the differential equations which are the generalization of the RG equations for non-renormalizable theories. Here we mainly focus on solving and analyzing these equations. We discuss the properties of the obtained solutions and interpretation of the results.

description: The Discontinuous Galerkin (DG) electronic structure method employs an adaptive local basis (ALB) set to solve the Kohn-Sham equations of density functional theory (DFT) in a discontinuous Galerkin framework. The adaptive local basis is generated on-the-fly to capture the local material physics, and can systematically attain chemical accuracy with only a few tens of degrees of freedom per atom. A central issue for large-scale calculations, however, is the computation of the electron density (and subsequently, ground state properties) from the discretized Hamiltonian in an efficient and scalable manner. We show in this work how Chebyshev polynomial filtered subspace iteration (CheFSI) can be used to address this issue and push the envelope in large-scale materials simulations in a discontinuous Galerkin framework. We describe how the subspace filtering steps can be performed in an efficient and scalable manner using a two-dimensional parallelization scheme, thanks to the orthogonality of the DG basis set and block-sparse structure of the DG Hamiltonian matrix. The on-the-fly nature of the ALBs requires additional care in carrying out the subspace iterations. We demonstrate the parallel scalability of the DG-CheFSI approach in calculations of large-scale two-dimensional graphene sheets and bulk three-dimensional lithium-ion electrolyte systems. Employing 55,296 computational cores, the time per self-consistent field iteration for a sample of the bulk 3D electrolyte containing 8,586 atoms is 90 seconds, and the time for a graphene sheet containing 11,520 atoms is 75 seconds.

description: Within one-dimensional disordered models of interacting fermions we perform a numerical study of several dynamical density correlations, which can serve as hallmarks of the transition to the many-body localized state. Results confirm that density-wave correlations exhibit quite abrupt change with the increasing disorder, with nonvanishing long-time value characteristic for nonergodic phase. In addition, our results reveal in a wide time-window a logarithmic variation of correlations in time, which we can bring in connection with the anomalous behavior of the dynamical conductivity near the transition. Our result support the view that transition to many-body localization can be characterized by universal dynamical exponents.

description: In most glass-forming materials external perturbations are relaxed in a non-exponential fashion. It is shown that the degree of non-exponentiality is phenomenologically correlated with the departure from simple thermally activated behavior as measured by the fragility index m. In model glass formers such as the Ge-As-Se ternary alloy, and to some degree for amorphous materials in general, the correlations with these properties are observed also for other characteristic features. These include the specific heat step and the aging kinetics in the glass transformation range. While phenomenological correlations have proven very useful for rationalizing the properties of many glass formers, they have provided little direct insight into the nature of the non-exponential relaxation itself. In this respect the invention of spectrally selective techniques, allowing to manipulate the observable primary response, has yielded evidence for its heterogeneous character. As an example of these developments the implications of some recent reduced 4D deuteron magnetic resonance experiments on a supercooled liquid are discussed.

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: This work aims at exploring the scaling relations among rocky exoplanets. With the assumption of internal gravity increasing linearly in the core, and staying constant in the mantle, and tested against numerical simulations, a simple model is constructed, applicable to rocky exoplanets of core mass fraction (CMF) $\in 0.1\sim0.4$ and mass $\in 0.1 \sim 10 M_{\oplus}$. Various scaling relations are derived: (1) core radius fraction $\rm CRF \approx \sqrt{CMF}$, (2) Typical interior pressure $P_{\text{typical}} \sim g_{\rm{s}}^2$ (surface gravity squared), (3) core formation energy $E_{\rm diff} \sim \frac{1}{10} E_{\rm grav}$ (the total gravitational energy), (4) effective heat capacity of the mantle $C_{\rm p}\approx \left( \frac{M_{\rm{p}}}{M_{\oplus}} \right) \cdot 7 \cdot 10^{27}$ J K$^{-1}$, and (5) the moment of inertia $I\approx \frac{1}{3} \cdot M_{\rm{p}} \cdot R_{\rm{p}}^2$. These scaling relations, though approximate, are handy for quick use owing to their simplicity and lucidity, and provide insights into the interior structures of rocky exoplanets. As examples, this model is applied to several planets including Earth, GJ 1132b, Kepler-93b, and Kepler-20b, and made comparison with the numerical method.

Aging, rejuvenation, and memory phenomena in a lead-based relaxor ferroelectric
Creators: name: Böhmer, Roland
name: Kircher, O.
Publisher: name: Springer
Year: 2002
Subjects: subject: 530

description: Isothermal aging and temperature cycle experiments were done on the relaxor ferroelectric lead magnesium niobate mixed with 10% lead titanate (PMN-10PT) around and below the diffuse maximum of the dielectric loss. With increasing aging time tw the isothermal evolution of the linear susceptibility follows a power law and does not show frequency scaling. The non-linear susceptibility, however, obeys nearly perfect ωt w-scaling. After aging the sample at a single temperature we observed both rejuvenation and memory effects in temperature cycle experiments. This observation indicates symmetric behavior in the sense that it shows up irrespective of whether cooling with subsequent re-heating or heating with subsequent re-cooling was performed. The memory effect is absent if subsequent to aging the temperature is increased significantly above that corresponding to the maximum in the dielectric loss. The symmetric behavior within negative and positive temperature cycles under these conditions can be rationalized by the notion of movable domain walls. These become fixed in their configuration on a large spatial scale while more flexible wall segments still show re-conformation processes when cooling or heating the sample after aging.

description: We present a new method of constructing a fully robust qubit in a three-level system. By the application of continuous driving fields, robustness to both external and controller noise is achieved. Specifically, magnetic noise and power fluctuations do not operate within the robust qubit subspace. Whereas all the continuous driving based constructions of such a fully robust qubit considered so far have required at least four levels, we show that in fact only three levels are necessary. This paves the way for simple constructions of a fully robust qubit in many atomic and solid state systems that are controlled by either microwave or optical fields. We focus on the NV-center in diamond and analyze the implementation of the scheme, by utilizing the electronic spin sub-levels of its ground state. In current state-of-the-art experimental setups the scheme leads to improvement of more than two orders of magnitude in coherence time, pushing it towards the lifetime limit. We show how the fully robust qubit can be used to implement quantum sensing, and in particular, the sensing of high frequency signals.

description: Deliverable 6.3 reports on the education and training activities, including data on users participation and involvement. In D6.1 we had proposed our structured Education and Training plan, aimed at bridging the skills gap between HPC development and computational materials science. This plan is being effectively implemented through different actions, which in the first 18 months include: a. Eight training initiatives --schools, tutorials, workshops-- directly designed, organized and co-funded by MaX (sometimes in cooperation with others). The emphasis was on hands-on-activities based on MaX flagship codes and frontier HPC developments, and on the involvement of young participants. The overall assessment of these initiatives by the participants (approx 400 in total) was extremely positive. b. A few lectures / modules offered by MaX within schools organized by other institutions. c. Major contributions to innovative education pilots within three University MSci courses, plus one MOOC course under development. These initiatives have resulted in the production of valuable training material, that have been handed out to students in preliminary form and will be made available to the broader community in the next months, once refined. Most partners have been heavily involved in the activities: Juelich, CNR, SISSA, ICN2, EPFL, CINECA, BSC, ETH Zürich, KTH, CloudWeavers, and UNESCO. Importantly, a significant number of activities have combined synergic contributions from different MaX partners with complementary expertise. Finally, MaX is maintaining an on-line repository of training initiatives of interest to the computational materials research community, which is useful to potential participants and also helps organizers in coordinating, identifying needs and avoiding overlaps.

description: Single-photon devices at microwave frequencies are important for applications in quantum information processing and communication in the microwave regime. In this work, we describe a proposal of a multi-output single-photon device. We consider two superconducting resonators coupled to a gap-tunable qubit via both its longitudinal and transverse degrees of freedom. Thus, this qubit-resonator coupling differs from the coupling in standard circuit quantum-electrodynamic systems described by the Jaynes-Cummings model. We demonstrate that an effective quadratic coupling between one of the normal modes and the qubit can be induced, and this induced second-order nonlinearity is much larger than that for conventional Kerr-type systems exhibiting photon blockade. Assuming that a coupled normal mode is resonantly driven, we observe that the output fields from the resonators exhibit strong sub-Poissonian photon-number statistics and photon antibunching. Contrary to previous studies on resonant photon blockade, the first-excited state of our device is a pure single-photon Fock state rather than a polariton state, i.e., a highly hybridized qubit-photon state. In addition, it is found that the optical state truncation caused by the strong qubit-induced nonlinearity can lead to an entanglement between the two resonators, even in their steady state under the Markov approximation.

STDP allows close-to-optimal spatiotemporal spike pattern detection by single coincidence detector neurons

description: By recording multiple cells simultaneously, electrophysiologists have found evidence for repeating spatiotemporal spike patterns, which can carry information. How this information is extracted by downstream neurons is unclear. In this theoretical paper, we investigate to what extent a single cell could detect a given spike pattern and what the optimal parameters to do so are, in particular the membrane time constant $τ$. Using a leaky integrate-and-fire (LIF) neuron with instantaneous synapses and homogeneous Poisson input, we were able to compute this optimum analytically. Our results indicate that a relatively small $τ$ (at most a few tens of ms) is usually optimal, even when the pattern is much longer. This is somewhat counter intuitive as the resulting detector ignores most of the pattern, due to its fast memory decay. Next, we wondered if spike-timing-dependent plasticity (STDP) could enable a neuron to reach the theoretical optimum. We simulated a LIF neuron equipped with additive spike-timing-dependent potentiation and homeostatic rate-based depression, and repeatedly exposed it to a given input spike pattern. As in previous studies, the LIF progressively became selective to the repeating pattern with no supervision, even when the pattern was embedded in Poisson activity. Here we show that, using certain STDP parameters, the resulting pattern detector can be optimal. Taken together, these results may explain how humans can learn repeating visual or auditory sequences. Long sequences could be recognized thanks to coincidence detectors working at a much shorter timescale. This is consistent with the fact that recognition is still possible if a sound sequence is compressed, played backward, or scrambled using 10ms bins. Coincidence detection is a simple yet powerful mechanism, which could be the main function of neurons in the brain.

To prevent and control PEDV infections, the availability of upgraded and rapid virus detection techniques is crucial. The clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein (Cas)13a system, namely, programmability of CRISPR RNA (crRNA) and “collateral” promiscuous RNase activity of Cas13a after target RNA identification. In this study, we aimed to develop a recombinase polymerase amplification (RPA)-based CRISPR-Cas13a approach for PEDV diagnosis for the first time. The results showed that up to 10 copies of the target PEDV DNA standard/µL were detected after 40 min at 37 °C. PEDV detection exhibited remarkable specificity compared to that of other selected pathogens. Additionally, this RPA-based CRISPR-Cas13a approach could be used to clinical samples, with similar performance to that of reverse transcription-quantitative polymerase chain reaction (RT–qPCR). The results of our proposed approach were visualized using either lateral flow strips or fluorescence for field-deployable viral diagnostics, thereby facilitating its use in endemic regions. Overall, our proposed approach showed good reliability, sensitivity, and specificity, suggesting that it is applicable for detecting other viruses in diagnosing diseases and inspecting food safety.

description: Laser cutting of carbon fibre-reinforced plastics (CFRP) is a promising alternative to traditional manufacturing methods due to its non-contact nature and high automation potential. To establish the process for an industrial application, it is necessary to predict the temperature fields arising as a result of the laser energy input. Elevated temperatures during the cutting process can lead to damage in the composite’s matrix material, resulting in local changes in the structural properties and reduced material strength. To address this, a three-dimensional finite element model is developed to predict the temporal and spatial temperature evolution during laser cutting. Experimental values are compared with simulated temperatures, and the cutting kerf geometry is examined. Experiments are conducted at 45° and 90° cutting angles relative to the main fibre orientation using a 1.1 mm thick epoxy-based laminate. The simulation accurately captures the overall temperature field expansion caused by multiple laser beam passes over the workpiece. The influence of fibre orientation is evident, with deviations in specific temperature data indicating differences between the estimated and real material properties. The model tends to overestimate the ablation rate in the kerf geometry, attributed to mesh resolution limitations. Within the parameters investigated, hardly any expansion of a heat affected zone (HAZ) is visible, which is confirmed by the simulation results.

description: A large variety of interacting complex systems are characterized by interactions occurring between more than two nodes. These systems are described by simplicial complexes. Simplicial complexes are formed by simplices (nodes, links, triangles, tetrahedra etc.) that have a natural geometric interpretation. As such simplicial complexes are widely used in quantum gravity approaches that involve a discretization of spacetime. Here, by extending our knowledge of growing complex networks to growing simplicial complexes we investigate the nature of the emergent geometry of complex networks and explore whether this geometry is hyperbolic. Specifically we show that an hyperbolic network geometry emerges spontaneously from models of growing simplicial complexes that are purely combinatorial. The statistical and geometrical properties of the growing simplicial complexes strongly depend on their dimensionality and display the major universal properties of real complex networks (scale-free degree distribution, small-world and communities) at the same time. Interestingly, when the network dynamics includes an heterogeneous fitness of the faces, the growing simplicial complex can undergo phase transitions that are reflected by relevant changes in the network geometry.

description: Ο τομέας της ηλεκτροκίνησης γνωρίζει τα τελευταία χρόνια αλματώδη ανάπτυξη σε παγκόσμιο επίπεδο. Η μείωση της διαθεσιμότητας των συμβατικών καυσίμων (πετρέλαιο, φυσικό αέριο), μαζί με την προσπάθεια για μικρότερο ενεργειακό αποτύπωμα οδήγησαν στην αναβίωση της ιδέας των ηλεκτρικών οχημάτων, ιδέα που όπως φαίνεται και από την ανάλυση που πραγματοποιείται στην αρχή της παρούσας διπλωματικής εργασίας, υπήρχε από τις αρχές του 20ου αιώνα και δεν είχε εγκαταλειφθεί ποτέ εντελώς. Στον αντίποδα της ηλεκτροκίνησης βέβαια στέκονται οι μηχανές εσωτερικής καύσεως με υδρογόνο ως καύσιμο, αλλά η τεχνολογία τους δεν είναι ακόμα τόσο ώριμη.
Η βασική τεχνολογία των ηλεκτρικών οχημάτων (μετατροπείς ηλεκτρικής ενέργειας) ήταν έτοιμη εδώ και δεκαετίες και έχει ενσωματωθεί χωρίς δυσκολία στα ηλεκτρικά οχήματα. Τα πρότυπα φόρτισης δημιουργήθηκαν σε αρκετά σύντομο χρονικό διάστημα αν και εν υπάρχει ακόμα πλήρης συμβατότητα σε παγκόσμιο επίπεδο. Η έρευνα αυτή την στιγμή έχει επικεντρωθεί στην αύξηση της αυτονομίας μέσω της βελτίωσης των συσσωρευτών και στην μείωση του χρόνου φόρτισης. Συνεχής είναι η έρευνα προς αυτήν την κατεύθυνση και τα αποτελέσματα είναι ενθαρρυντικά.
Ένα άλλο ζήτημα που απασχολεί την επιστημονική κοινότητα είναι αυτό της ετοιμότητας του ηλεκτρικού δικτύου να δεχθεί και να υποστηρίξει τον όγκο της ζητούμενης ηλεκτρικής ενέργειας από τα ηλεκτρικά οχήματα. Το πρόβλημα αυτό αντιμετωπίζεται με επιτυχία με την ένταξη των μικροδικτύων ή αλλιώς έξυπνων δικτύων στη λειτουργία του ηλεκτρικού δικτύου. Η ιδέα των μικροδικτύων οδηγεί στην αποκέντρωση των λειτουργιών με στόχο την καλύτερη εκμετάλλευση και τον αρτιότερο έλεγχο των λειτουργιών του ηλεκτρικού δικτύου.
Όλα τα παραπάνω παρουσιάζονται στην παρούσα διπλωματική εργασία, στην οποία πραγματοποιείται και μια οικονομική ανάλυση ενός σταθμού φόρτισης ηλεκτρικών αυτοκινήτων.

description: Background: Lactose intolerance (LI) is a pathological condition characterized by the inability to digest a sugar, lactose, due to absence or insufficient activity of lactase enzyme (β-galactosidase). The prevalence of LI varies mainly with age, ethnicity, dose of lactose administered, and the laboratory method used for its diagnosis. Currently, LI treatment is based on empirical diagnosis. Laboratory diagnostic procedures for LI are poorly practiced in Ethiopia. Thus, it is difficult to discuss exactly about LI situation in Ethiopia. Objective: To determine the magnitude and associated factors of lactose intolerance among malnourished under five children in Yekatit 12 Hospital Medical College, Addis Ababa, Ethiopia from March – July, 2018. Method: A cross-sectional study was conducted among malnourished under five children admitted in pediatric unit, Yekatit 12 Hospital Medical College. By using convenient sampling technique structured questionnaire was administered to gather information on the socio-demographic characteristics of study participants and associated risk factors of LI. Moreover, fresh stool sample was collected from the study participants to measure stool pH by use of pH papers, reducing substances by use of Benedict's solution and microscopy examination for intestinal parasites. Data analysis was done using the Statistical Package for Social Sciences (SPSS 21) software. Results: The study included 169 malnourished under five children. Among those 90 (53.3%) were male with median age of 12 months. The magnitude of LI was 18.3%. Among the study participants highest numbers of LI cases were in age group of less than 12 month 17(10.1%) followed by 13-24 month 13(7.7%). The factors that show significant association with lactose intolerance on bi-variate logistic analysis were family history of lactose intolerance (P=0.043) and diarrhea (P=0.000). In addition; problem after taking milk (P=0.007), type of therapeutic milk formula (P=0.000) and frequency of stool/24hr (P=0.023) were found to be the independent predictor factors of lactose intolerance in the study population. Conclusion: The magnitude of LI was high in the study setting. Thus it necessary to give more attention on the proper diagnosis of LI. In addition, similar large scale studies at molecular level is required to strengthen the present findings about LI in Ethiopia.

description: The glass transition is the most enduring grand-challenge problem in contemporary condensed matter physics. Here, we review the contribution of colloid experiments to our understanding of this problem. First, we briefly outline the success of colloidal systems in yielding microscopic insights into a wide range of condensed matter phenomena. In the context of the glass transition, we demonstrate their utility in revealing the nature of spatial and temporal dynamical heterogeneity. We then discuss the evidence from colloid experiments in favor of various theories of glass formation that has accumulated over the last two decades. In the next section, we expound on the recent paradigm shift in colloid experiments from an exploratory approach to a critical one aimed at distinguishing between predictions of competing frameworks. We demonstrate how this critical approach is aided by the discovery of novel dynamical crossovers within the range accessible to colloid experiments. We also highlight the impact of alternate routes to glass formation such as random pinning, trajectory space phase transitions and replica coupling on current and future research on the glass transition. We conclude our review by listing some key open challenges in glass physics such as the comparison of growing static lengthscales and the preparation of ultrastable glasses, that can be addressed using colloid experiments.
