Celeste Ng’s novel Everything I Never Told You (2014) has been said to combine some stock ingredients of literary thrillers with other less customary features that complicate its classification in that genre. Although we learn from page one that the protagonist of the novel, sixteen-year-old Lydia Lee, is dead, discovering who is behind the possible murder of this Chinese American girl proves to be one of the lesser mysteries in the story. While the reader remains intrigued by the forces/people that may have driven Lydia to her demise, other enigmas—related to the other members of the Lee family—keep cropping up and turn out to be closely linked to the protagonist’s fate. This article explores the secret-saturated structure of the novel, which moves back and forth between the Lees’ speculations about Lydia’s death, the impact that the event has on their lives and the protagonist’s own version of the story. Ng delves deep into the issues of gender, race and other types of otherness that spawn most of the secrets driving the story. Assisted by theories expounded by Frank Kermode, Derek Attridge and other scholars, the article highlights the centrality of family secrets as a structuring principle in Ng’s novel.

AbstractWe study amenability of definable groups and topological groups, and prove various results, briefly described below. Among our main technical tools, of interest in its own right, is an elaboration on and strengthening of the Massicot-Wagner version (Massicot and Wagner in J Ec Polytech Math 2:55–63, 2015) of the stabilizer theorem (Hrushovski in J Am Math Soc 25:189–243, 2012), and also some results about measures and measure-like functions (which we call means and pre-means). As an application we show that if G is an amenable topological group, then the Bohr compactification of G coincides with a certain “weak Bohr compactification” introduced in Krupiński and Pillay (Adv Math 345:1253–1299, 2019). In other words, the conclusion says that certain connected components of G coincide: $$G^{00}_{{{\,\mathrm{{top}}\,}}} = G^{000}_{{{\,\mathrm{{top}}\,}}}$$ G top 00 = G top 000 . We also prove wide generalizations of this result, implying in particular its extension to a “definable-topological” context, confirming the main conjectures from Krupiński and Pillay (2019). We also introduce $$\bigvee $$ ⋁ -definable group topologies on a given $$\emptyset $$ ∅ -definable group G (including group topologies induced by type-definable subgroups as well as uniformly definable group topologies), and prove that the existence of a mean on the lattice of closed, type-definable subsets of G implies (under some assumption) that $${{\,\mathrm{{cl}}\,}}(G^{00}_M) = {{\,\mathrm{{cl}}\,}}(G^{000}_M)$$ cl ( G M 00 ) = cl ( G M 000 ) for any model M. Secondly, we study the relationship between (separate) definability of an action of a definable group on a compact space [in the sense of Gismatullin et al. (Ann Pure Appl Log 165:552–562, 2014)], weakly almost periodic (wap) actions of G [in the sense of Ellis and Nerurkar (Trans Am Math Soc 313:103–119, 1989)], and stability. We conclude that any group G definable in a sufficiently saturated structure is “weakly definably amenable” in the sense of Krupiński and Pillay (2019), namely any definable action of G on a compact space supports a G-invariant probability measure. This gives negative solutions to some questions and conjectures raised in Krupiński (J Symb Log 82:1080–1105, 2017) and Krupiński and Pillay (2019). Stability in continuous logic will play a role in some proofs in this part of the paper. Thirdly, we give an example of a $$\emptyset $$ ∅ -definable approximate subgroup X in a saturated extension of the group $${{\mathbb {F}}}_2 \times {{\mathbb {Z}}}$$ F 2 × Z in a suitable language (where $${{\mathbb {F}}}_2$$ F 2 is the free group in 2-generators) for which the $$\bigvee $$ ⋁ -definable group $$H:=\langle X \rangle $$ H : = ⟨ X ⟩ contains no type-definable subgroup of bounded index. This refutes a conjecture by Wagner and shows that the Massicot-Wagner approach to prove that a locally compact (and in consequence also Lie) “model” exists for each approximate subgroup does not work in general (they proved in (Massicot and Wagner 2015) that it works for definably amenable approximate subgroups).

Nanocomposite formulation is still in its evolving state. However due to its significant therapeutic applications it has grabbed the attention of many researchers. Isoflavonewhich is widely found in soy products have tremendous medicinal propertieswhen it interacts with nanoparticles can become a boon. Hence in this study, we are reporting the interaction properties/patterns of two ubiquitous flavones namelyGlycitein and Genistein forming a nanocomposite model with 12 different metals such as Gold, Silver, Palladium, Platinum, Ruthenium, Rhodium, Cadmium, Iron, Nickel, Zinc, Copper and Antimony based ontheir potency to form nanoparticles. To mimic the Nanocomposite, model the formulation was conducted in Avogadro Software for windows. Glycitein and Genistein create a possibility of selecting the most suitable -OH position that would serve as the binding site. On selection of the appropriate binding site the interaction amid two molecules of glycitein and genistein placed sidewise held together by above-mentioned metals also surrounded by the same metal on another vacant -OH position forming a close saturated structure subjected for interaction. Based on predominantly energy levels the least energy obtained model was Cadmium and the peak procured by Antimony making it least stable and unfavorable for the perceived result.

The analysis of mechanic-electromagnetic effects of the Earth’s crust made it possible to distinguish the relation of rock induced polarization with its deformation. On the basis of these relations, their generalized description is made. It is shown that, although the Earth’s crust is an energy-saturated structure in a critical state, but owing to electromagnetic properties, it is not a medium in which electromagnetic oscillations can be generated in the low-frequency region. At the same time, the Earth’s crust is favourable environment for the occurrences of seismo-acoustic oscillations. It is shown that the mechanisms of mechanic-electromagnetic transformations of the crust generate electromagnetic waves accompanying seismic-acoustic disturbances. Examples of these waves manifestations in electric currents and in electromagnetic radiation are given.

The performance of sulfonamide and macrolide antibiotics in a spiked water removed by O3and O3/H2O2was evaluated uder different conditions such as ozone dosage, pH and H2O2/O3mole ratio. The results showed that O3and O3/H2O2were proved to be effective to oxdize sulfamethoxazole of sulfonamides containing the aromatic ring and erythromycin of macrolides, which were built of mostly saturated hydrocarbon structure, and O3was preferentially to oxidize sulfamethoxazole. With the reaction time of 30 min, when the ozone cocentrations were 2mg/L and 3mg/L, sulfamethoxazole and erythromycin removal efficiency was 93% and 91%, respectively. The sulfamethoxazole and erythromycin were removed completely within 30 min with ozone 6 mg/L. Degradation of sulfamethoxazole containing unsaturated C-C bonds occured easier at low pH only by O3. Degradation of erythromycin with fully saturated structure was difficult, but the improved removal efficiency could be obtained at higher pH. The high concentratins of H2O2to ozonation was favor to remove those antibiotics. At the 0.5 mole ratio of H2O2/O3,the highest removal efficiency could be reached for all the antibiotics .

AbstractIn this paper we answer the following well-known open question in computable model theory. Does there exist a computable not ℵ0-categorical saturated structure with a unique computable isomor-phism type? Our answer is affirmative and uses a construction based on Kolmogorov complexity. With a variation of this construction, we also provide an example of an ℵ1-categorical but not ℵ0-categorical saturated -structure with a unique computable isomorphism type. In addition, using the construction we give an example of an ℵ1-categorical but not ℵ0-categorical theory whose only non-computable model is the prime one.

AbstractIn the early eighties, answering a question of A. Macintyre, J. H. Schmerl ([13]) proved that every countable recursively saturated structure, equipped with a function β encoding the finite functions, is the β-closure of an infinite indiscernible sequence. This result implies that every countably saturated structure, in a countable but not necessarily recursive language, is an Ehrenfeucht-Mostowski model, by which we mean that the structure expands, in a countable language, to the Skolem hull of an infinite indiscernible sequence (in the new language).More recently, D. Lascar ([5]) showed that the saturated model of cardinality ℵ1 of an ω-stable theory is also an Ehrenfeucht-Mostowski model.These results naturally raise the following problem: which (countable) complete theories have an uncountably saturated Ehrenfeucht-Mostowski model. We study a generalization of this question. Namely, we call ACI-model a structure which can be expanded, in a countable language L′, to the algebraic closure (in L′) of an infinite indiscernible sequence (in L′). And we try to characterize the λ-saturated structures which are ACI-models.The main results are the following. First it is enough to restrict ourselves to ℵ1-saturated structures: if T has an ℵ1-saturated ACI-model then, for every infinite λ, T has a λ-saturated ACI-model. We obtain a complete answer in the case of stable theories: if T is stable then the three following properties are equivalent: (a) T is ω-stable, (b) T has an ℵ1-saturated ACI-model, (c) every saturated model of T is an Ehrenfeucht-Mostowski model. The unstable case is more complicated, however we show that if T has an ℵ1-saturated ACI-model then T doesn't have the independence property.

AbstractDiamond is a metastable phase, while graphite is a stable phase in low pressure equilibrium phase diagrams of carbon. However, diamond with saturated structure of π bonds is more stable than graphite with unsaturated structure of n bonds during the existence of activated particles generated by plasma. That provides an excellent explanation for the plasma and other activated CVD diamond growth under low pressure taking place with simultaneous graphite etching.
