description: Systems with artificial intelligence components, so-called AI-based systems, have gained considerable attention recently. However, many organizations have issues with achieving production readiness with such systems. As a means to improve certain software quality attributes and to address frequently occurring problems, design patterns represent proven solution blueprints. While new patterns for AI-based systems are emerging, existing patterns have also been adapted to this new context.
 The goal of this study is to provide an overview of design patterns for AI-based systems, both new and adapted ones. We want to collect and categorize patterns, and make them accessible for researchers and practitioners. To this end, we first performed a multivocal literature review (MLR) to collect design patterns used with AI-based systems. We then integrated the created pattern collection into a web-based pattern repository to make the patterns browsable and easy to find.
 As a result, we selected 51 resources (35 white and 16 gray ones), from which we extracted 70 unique patterns used for AI-based systems. Among these are 34 new patterns and 36 traditional ones that have been adapted to this context. Popular pattern categories include "architecture" (25 patterns), "deployment" (16), "implementation" (9), or "security & safety" (9). While some patterns with four or more mentions already seem established, the majority of patterns have only been mentioned once or twice (51 patterns). Our results in this emerging field can be used by researchers as a foundation for follow-up studies and by practitioners to discover relevant patterns for informing the design of AI-based systems.

description: If forthcoming measurements of cosmic photon polarization restrict the primordial tensor-to-scalar ratio to $r < 0.01$, small field inflation will be a principal candidate for the origin of the universe. Here we show that small multifield inflation, without the hybrid mechanism, typically results in large squeezed nongaussianity. Small multifield potentials contain multiple flat field directions, often identified with the gauge invariant field directions in supersymmetric potentials. We find that unless these field directions have equal slopes, large nongaussianity arises. After identifying relevant differences between large and small two-field potentials, we demonstrate that the latter naturally fulfill the Byrnes-Choi-Hall large nongaussianity conditions. Computations of the primordial power spectrum, spectral index, and squeezed bispectrum, reveal that small two-field models which otherwise match observed primordial perturbations, produce excludably large nongaussianity if the inflatons' field directions have unequal slopes.

description: † Rovnoscydmus sp. specimen 4
(Figs 17, 135–138)
Material studied. Late Eocene of Europe, Rovno amber: sex unknown; inclusion in elongate, trapezoidal prism of amber 12 mm long (Fig. 17), collection number K-8970 (SIZK).
Description. Body (Figs 135–138) elongate, slender and relatively strongly convex, light brown; BL 0.93 mm.
Head (Figs 135–138) broadest at eyes, HL 0.18 mm, HW 0.18 mm; vertex and frons confluent, together subtrapezoidal and moderately transverse; supraantennal tubercles indistinct; compound eyes large, strongly convex, bean-shaped; tempora slightly longer than eyes. Punctures on frons and vertex (Fig. 138) fine and unremarkable, separated by spaces 3–4 × as wide as diameters of punctures; setae (Fig. 138) sparse, short and suberect. Antennae (Figs 135–138) much shorter than half BL, AnL 0.36 mm, antennal club relatively well demarcated; antennomeres I–II strongly elongate, III–VI seems to be slightly elongate, VII about as long as broad, VIII–X transverse, XI much shorter than IX–X combined, about 1.3 × as long as broad, with rounded apex.
Pronotum (Figs 136, 138) elongate, broadest site not possible to define; PL 0.23 mm, PW 0.20 mm; punctures on disc (Fig. 138) small but distinct, separated by spaces 3–4 × as wide as diameters of punctures; setae (Fig. 138) short and sparse, nearly recumbent.
Elytra (Figs 136–138) elongate oval, strongly convex, broadest in front of middle, EL 0.53 mm, EW 0.35 mm, EI 1.50; punctures and setae on elytra poorly visible.

description: Today, many systems use artificial intelligence (AI) to solve complex problems. While this often increases system effectiveness, developing a production-ready AI-based system is a difficult task. Thus, solid AI engineering practices are required to ensure the quality of the resulting system and to improve the development process. While several practices have already been proposed for the development of AI-based systems, detailed practical experiences of applying these practices are rare.
 In this paper, we aim to address this gap by collecting such experiences during a case study, namely the development of an autonomous stock trading system that uses machine learning functionality to invest in stocks. We selected 10 AI engineering practices from the literature and systematically applied them during development, with the goal to collect evidence about their applicability and effectiveness. Using structured field notes, we documented our experiences. Furthermore, we also used field notes to document challenges that occurred during the development, and the solutions we applied to overcome them. Afterwards, we analyzed the collected field notes, and evaluated how each practice improved the development. Lastly, we compared our evidence with existing literature.
 Most applied practices improved our system, albeit to varying extent, and we were able to overcome all major challenges. The qualitative results provide detailed accounts about 10 AI engineering practices, as well as challenges and solutions associated with such a project. Our experiences therefore enrich the emerging body of evidence in this field, which may be especially helpful for practitioner teams new to AI engineering.

description: In this manuscript we present a method for the quantitative comparison of two surfaces, applicable to temporal and/or spatial extent in one or two dimensions. Often surface comparisons are simply overlaid graphs of results from different methodologies that are qualitative at best; it is the purpose of this work to facilitate quantitative evaluation. The surfaces can be analytical, numerical, and/or experimental, and the result returned by the method, termed surface similarity parameter or normalized error, has been normalized so that its value lies between zero and one. When the parameter has a value of zero, the surfaces are in perfect agreement, whereas a value of one is indicative of perfect disagreement. To provide insight regarding the magnitude of the parameter, several canonical cases are presented, followed by results from breaking water wave experimental measurements with numerical simulations, and by a comparison of a prescribed, periodic, square-wave surface profile and the subsequent manufactured surface.

description: An amperometric fluorinated xerogel-derived nitric oxide (NO) microelectrode is described. A range of fluorine-modified xerogel polymers were synthesized via the co-hydrolysis and condensation of alkylalkoxy- and fluoroalkoxysilanes. Such polymers were evaluated as NO sensor membranes to identify the optimum composition for maximizing NO permeability while providing sufficient selectivity for NO in the presence of common interfering species. By taking advantage of both the versatility of sol–gel chemistry and the “poly(tetrafluoroethylene) (PTFE)-like” high NO permselective properties of the xerogels, the performance of the fluorinated xerogel-derived sensors was excellent, surpassing all miniaturized NO sensors reported to date. In contrast to previous electrochemical NO sensor designs, xerogel-based NO microsensors were fabricated using a simple, reliable dip-coating procedure. An optimal permselective membrane was achieved by synthesizing xerogels of methyltrimethoxysilane (MTMOS) and 20% (heptadecafluoro-1,1,2,2-tetrahydrodecyl)trimethoxysilane (17FTMS, balance MTMOS) under acid-catalyzed conditions. The resulting NO microelectrode had a conical tip of ~20 μm in diameter and ~55 mm in length, and exhibited sensitivities of 7.91 pA·nM−1 from 0.2 to 3.0 nM (R2 = 0.9947) and 7.60 nA·mM−1 from 0.5 to 4.0 μM (R2 = 0.9999), detection limit of 83 pM (S/N = 3), response time (t95%) of <3 sec, and selectivity (logKNO,jamp) of −5.74, <−6, <−6, <−6, <−6, −5.84, and −1.33 for j = nitrite, ascorbic acid, uric acid, acetaminophen, dopamine, ammonia/ammonium, and carbon monoxide. In addition, the sensor proved functional up to 20 d, maintaining ≥90% of the sensor's initial sensitivity without serious deterioration in selectivity.

description: Several groups have identified an extended excess of gamma rays over the modeled foreground and background emissions towards the Galactic center (GC) based on observations with the Fermi Large Area Telescope. This excess emission is compatible in morphology and spectrum with a telltale sign from dark matter (DM) annihilation. Here, we present a critical reassessment of DM interpretations of the GC signal in light of the foreground and background uncertainties that some of us recently outlaid in Calore et al. 2014. We find that a much larger number of DM models fits the gamma-ray data than previously noted. In particular: (1) In the case of DM annihilation into $\bar{b}b$, we find that even large DM masses up to $m_χ\simeq$ 74 GeV are allowed with a $p$-value $> 0.05$. (2) Surprisingly, annihilation into non-relativistic hh gives a good fit to the data. (3) The inverse Compton emission from $μ^+μ^-$ with $m_χ\sim$ 60-70 GeV can also account for the excess at higher latitudes, $|b|>2^\circ$, both in its spectrum and morphology. We also present novel constraints on a large number of mixed annihilation channels, including cascade annihilation involving hidden sector mediators. Finally, we show that the current limits from dwarf spheroidal observations are not in tension with a DM interpretation when uncertainties on the DM halo profile are accounted for.

description: We establish a lower bound for the eigenvalues of the Dirac operator defined on a compact Kähler-Einstein manifold of positive scalar curvature and endowed with particular ${\rm spin}^c$ structures. The limiting case is characterized by the existence of Kählerian Killing ${\rm spin}^c$ spinors in a certain subbundle of the spinor bundle. Moreover, we show that the Clifford multiplication between an effective harmonic form and a Kählerian Killing ${\rm spin}^c$ spinor field vanishes. This extends to the ${\rm spin}^c$ case the result of A. Moroianu stating that, on a compact Kähler-Einstein manifold of complex dimension $4\ell+3$ carrying a complex contact structure, the Clifford multiplication between an effective harmonic form and a Kählerian Killing spinor is zero.

description: A microfabricated device has been developed in which electrospray ionization is performed directly from the corner of a rectangular glass microchip. The device allows highly efficient electrokinetically driven separations to be coupled directly to a mass spectrometer (MS) without the use of external pressure sources or the insertion of capillary spray tips. An electrokinetic-based hydraulic pump is integrated on the chip that directs eluting materials to the monolithically integrated spray tip. A positively charged surface coating, PolyE-323, is used to prevent surface interactions with peptides and proteins and to reverse the electroosmotic flow in the separation channel. The device has been used to perform microchip CE-MS analysis of peptides and proteins with efficiencies over 200 000 theoretical plates (1 000 000 plates/m). The sensitivity and stability of the microfabricated ESI source were found to be comparable to that of commercial pulled fused-silica capillary nanospray sources.

Description. Body (Figs 139–144) elongate, relatively stout and strongly convex, brown; BL 1.05 mm.
Head (Figs 139–144) broadest at eyes, HL 0.15 mm, HW 0.20 mm; poorly visible; supraantennal tubercles indistinct; compound eyes large, strongly convex, oval; tempora slightly shorter than eyes. Antennae (Figs 139– 143) distinctly shorter than half BL, AnL about 0.38 mm, antennal club indistinctly demarcated; antennomeres I–II elongate, III–IV seem to be slightly transverse, V slightly elongate, VI–VII about as long as broad, VIII transverse or about as long as broad, IX and X about as long as broad, XI much shorter than IX–X combined, about 1.2 × as long as broad, with rounded apex.
Pronotum (Figs 139, 142) round, broadest site not possible to define; PL 0.25 mm, PW 0.25 mm; punctures on disc (Fig. 142) small but distinct, separated by spaces 2–3 times as wide as diameters of punctures; setae (Fig. 142) short and sparse, nearly recumbent, on anterior portions of hypomera replaced by distinct thick bristles (Fig. 143).
Elytra (Figs 139, 142) elongate oval, strongly convex, broadest site not possible to define, EL 0.65 mm, EW about 0.48 mm, EI about 1.37; punctures similar to those on pronotum but slightly sparser; setae poorly visible (Fig. 142).

Remarks. This specimen seems to be stouter than remaining inclusions of Rovnoscydmus and may represent a separate species, but the state of preservation and orientation in amber make comparisons difficult. Alternatively, it may be conspecific with Rovnoscydmus specimens 4, 8 and? Rovnoscydmus specimen 10, as they were all found in one piece of amber.

description: We investigate the role played by particular field representations of an intermediate massive spin-1 boson in the context of spin-dependent interparticle potentials between fermionic sources in the limit of low momentum transfer. The comparison between the well-known case of the Proca field and that of an exchanged spin-1 boson (with gauge-invariant mass) described by a 2-form potential mixed with a 4-vector gauge field is established in order to pursue an analysis of spin- as well as velocity-dependent profiles of the interparticle potentials. We discuss possible applications and derive an upper bound on the product of vector and pseudo-tensor coupling constants.

They showed that a set of measurements is incompatible (i.e., not jointly measurable) if and only if it can be used for the demonstration of steering. In this paper, we prove the temporal analog of this result viz., a set of measurements are incompatible if and only if it exhibits temporal steering.

On the Concentration of the Minimizers of Empirical Risks

description: Obtaining guarantees on the convergence of the minimizers of empirical risks to the ones of the true risk is a fundamental matter in statistical learning. Instead of deriving guarantees on the usual estimation error, the goal of this paper is to provide concentration inequalities on the distance between the sets of minimizers of the risks for a broad spectrum of estimation problems. In particular, the risks are defined on metric spaces through probability measures that are also supported on metric spaces. A particular attention will therefore be given to include unbounded spaces and non-convex cost functions that might also be unbounded. This work identifies a set of assumptions allowing to describe a regime that seem to govern the concentration in many estimation problems, where the empirical minimizers are stable. This stability can then be leveraged to prove parametric concentration rates in probability and in expectation. The assumptions are verified, and the bounds showcased, on a selection of estimation problems such as barycenters on metric space with positive or negative curvature, subspaces of covariance matrices, regression problems and entropic-Wasserstein barycenters.
Blood oxygen level dependent functional magnetic resonance imaging of hippocampal subfields and cortical brain areas during cued recall associative memory

description: The use of functional magnetic resonance imaging (fMRI) presents a trade-off between spatial resolution and whole-brain analysis in current literature. The current study aims to address this compromise by utilizing Blood Oxygen Level Dependent (BOLD) fMRI on an ultrahigh resolution 7T scanner. The current study involves an associative memory task adapted from De Shetler and Rissman (2017), which was conducted on 22 healthy young adults. The analysis includes measuring whole-brain activation and percent signal change from regions of interest, including dentate gyrus, CA1, CA3, and subiculum. The findings indicate multiple regions in the cortex are involved in successful retrieval, but hippocampal subfield activity does not differ according to retrieval condition.
Mechanisms of Pulsed Laser Microbeam Release of SU-8 Polymer “Micropallets” for the Collection and Separation of Adherent Cells

description: The release of individual polymer micropallets from glass substrates using highly focused laser pulses has been demonstrated for the efficient separation, collection, and expansion of single, adherent cells from a heterogeneous cell population. Here, we use fast-frame photography to examine the mechanism and dynamics of micropallet release produced by pulsed laser microbeam irradiation at λ = 532 nm using pulse durations ranging between 240 ps and 6 ns. The time-resolved images show the laser microbeam irradiation to result in plasma formation at the interface between the glass coverslip and the polymer micropallet. The plasma formation results in the emission of a shock wave and the ablation of material within the focal volume. Ablation products are generated at high pressure due to the confinement offered by the polymer adhesion to the glass substrate. The ablation products expand underneath the micropallet on a time scale of several hundred nanoseconds. This expansion disrupts the polymer–glass interface and accomplishes the release of the pallet from its glass substrate on the microsecond time scale (∼1.5 μs). Our experimental investigation demonstrates that the threshold energy for pallet release is constant (∼2 μJ) over a 25-fold range of pulse duration spanning the picosecond to nanosecond domain. Taken together, these results implicate that pallet release accomplished via pulsed laser microbeam irradiation is an energy-driven plasma-mediated ablation process.

description: The searches for heavy Higgs bosons and supersymmetric (SUSY) particles at the LHC have left the minimal supersymmetric standard model (MSSM) with an unusual spectrum of SUSY particles, namely, all squarks are beyond a few TeV while the Higgs bosons other than the one observed at 125 GeV could be relatively light. In light of this, we study a scenario characterized by two scales: the SUSY breaking scale or the squark-mass scale $(M_S)$ and the heavy Higgs-boson mass scale $(M_A)$.We perform a survey of the MSSM parameter space with $M_S < 10^{10}$ GeV and $M_A < 10^4$ GeV such that the lightest Higgs boson mass is within the range of the observed Higgs boson as well as satisfying a number of constraints. The set of constraints include the invisible decay width of the $Z$ boson and that of the Higgs boson, the chargino-mass limit, dark matter relic abundance from Planck, the spin-independent cross section of direct detection by LUX, and gamma-ray flux from dwarf spheroidal galaxies and gamma-ray line constraints measured by Fermi LAT. Survived regions of parameter space feature the dark matter with correct relic abundance, which is achieved through either coannihilation with charginos, $A/H$ funnels, or both. We show that future measurements, e.g., XENON1T and LZ, of spin-independent cross sections can further squeeze the parameter space.

description: We study the nonequilibrium Keldysh Green's function for an N-orbital Anderson model at high bias voltages, extending a previous work, which for the case only with the spin degrees of freedom N=2, to arbitrary N. Our approach uses an effective non-Hermitian Hamiltonian that is defined with respect to a Liouville-Fock space in the context of a thermal field theory. The result correctly captures the relaxation processes at high energies, and is asymptotically exact not only in the high-bias limit but also in the high-temperature limit at thermal equilibrium. We also present an explicit continued-fraction representation of the Green's function. It clearly shows that the imaginary part is recursively determined by the decay rate of intermediate states with at most N-1 particle-hole-pair excitations. These high-bias properties follow from the conservations of a generalized charge and current in the Liouville-Fock space. We also examine temperature dependence of the spectral function in equilibrium, comparing the exact results with both the finite-T and infinite-T results of the non-crossing approximation (NCA).

description: Hybrid microchannels composed of poly(dimethylsiloxane) and glass were coated with supported bilayer membranes (SBMs) by the process of vesicle fusion. The electroosmotic mobility (µeo) of zwitterionic, positively charged, and negatively charged phospholipid membranes was measured over a 4-hour time to evaluate the stability of the coatings in an electric field. Coated microchips with a simple cross design were used to separate the fluorescent dyes fluorescein and Oregon Green. Migration time reproducibility was better than 5% RSD over 70 min of continuous separations. Separation of Oregon Green and fluorescein in channels coated with zwitterionic phosphatidylcholine (PC) membranes yielded efficiencies of 611,000 and 499,000 plates/m and a resolution of 2.4 within 2 s. Both zwitterionic and negatively charged membranes were used to separate peptide substrates from their phosphorylated analogs with efficiencies of 200,000–400,000 plates/m. Notably, separations of fluorescently labeled ABL substrate peptide from its phosphorylated counterpart were achieved using a high-salt physiological buffer with near-baseline resolution in 10 s. PC-coated devices were used to successfully separate enhanced green fluorescent protein (eGFP) from a fusion protein (eGFP-Crakl) with an efficiency of 358,000 and 278,000 plates/m respectively in less than 12 s. These SBM-based coatings may enable the separation of a broad range of analytes and may be ideal in biological applications for microfluidics.

description: Numerous theories have stressed the importance of parenting in the development of child psychopathology. Despite the well-established concurrent associations between parenting and child psychological disorders, the longitudinal relationships, especially cross-stage ones, are still inconclusive. In addition, research has shown that parental influences are amplified for children with adversity experiences. On top of that, recently, the Dimensional Model of Adversity and Psychopathology illustrates the importance of identifying distinct dimensions of adversity (threat & deprivation). Therefore, the current study investigated the longitudinal impacts of preschool parenting on adolescent psychopathology and the moderating role of different types of adversity exposure. At baseline when children were 2-5 years, multi-method measures were used to measure children’s overall psychopathology, parenting behaviors, and exposure to adversity. After 14 years, the participants, now in late adolescence, were re-contacted and 133 adolescents completed self-report measures of psychopathology by the time of data analysis. The results showed that neither negative nor positive preschool parenting behaviors were not significantly associated with adolescent internalizing, externalizing, or overall psychopathology. Exposure to threat, deprivation, or other adversities did not significantly moderate the associations examined above. Limitations were discussed in detail. Our study adds to the limited literature on cross-stage parental influences by further questioning whether parents play a crucial role in the development of adolescent psychopathology. It implies that future studies should consider the significance of parenting with caution and identify other factors contributing to psychopathology risk in adolescents.

description: We present a microscopic theory of magnon transport in ferromagnetic insulators (FIs). Using magnon injection through microwave pumping, we propose a way to generate magnon dc currents and show how to enhance their amplitudes in hybrid ferromagnetic insulating junctions. To this end focusing on a single FI, we first revisit microwave pumping at finite (room) temperature from the microscopic viewpoint of magnon injection. Next, we apply it to two kinds of hybrid ferromagnetic insulating junctions. The first is the junction between a quasi-equilibrium magnon condensate and magnons being pumped by microwave, while the second is the junction between such pumped magnons and noncondensed magnons. We show that quasi-equilibrium magnon condensates generate ac and dc magnon currents, while noncondensed magnons produce essentially a dc magnon current. The ferromagnetic resonance (FMR) drastically increases the density of the pumped magnons and enhances such magnon currents. Lastly, using microwave pumping in a single FI, we discuss the possibility that a magnon current through an Aharonov-Casher phase flows persistently even at finite temperature. We show that such a magnon current arises even at finite temperature in the presence of magnon-magnon interactions. Due to FMR, its amplitude becomes much larger than the condensed magnon current.

description: In lumped-element electrical circuit theory, the problem of solving Maxwell's equations in the presence of media is reduced to two sets of equations, the constitutive equations encapsulating local geometry and dynamics of a confined energy density, and the Kirchhoff equations enforcing conservation of charge and energy in a larger, topological, scale. We develop a new geometric and systematic description of the dynamics of general lumped-element electrical circuits as first order differential equations, derivable from a Lagrangian and a Rayleigh dissipation function. Through the Faddeev-Jackiw method we identify and classify the singularities that arise in the search for Hamiltonian descriptions of general networks. The core of our solution relies on the correct identification of the reduced manifold in which the circuit state is expressible, e.g., a mix of flux and charge degrees of freedom, including the presence of compact ones. We apply our fully programmable method to obtain (canonically quantizable) Hamiltonian descriptions of nonlinear and nonreciprocal circuits which would be cumbersome/singular if pure node-flux or loop-charge variables were used as a starting configuration space. We also propose a specific assignment of topology for the branch variables of energetic elements, that when used as input to the procedure gives results consistent with classical descriptions as well as with spectra of more involved quantum circuits. This work unifies diverse existent geometrical pictures of electrical network theory, and will prove useful, for instance, to automatize the computation of exact Hamiltonian descriptions of superconducting quantum chips.

description: Smart Information Systems (SIS), which are a combination of big data analytics and Artificial Intelligence (AI), constitute an integral part of our lives. From Google search, Amazon’s Alexa, surgery robots, digital libraries, location-based devices, affective computing, and human machine symbiosis, almost everybody in high-income regions is affected by SIS on daily basis. Meanwhile, human rights and ethics discussions about SIS are taking place whilst the technologies are already omnipresent. The UK House of Lords, the UNESCO, the European Commission and the Pope, are only a few examples of those working on the human rights and ethics aspects of SIS.
The Agreement of SphygmoCor XCEL and VICORDER Measures of Central Hemodynamics

description: Cardiovascular disease (CVD) is the number one cause of death in the United States and among the leading causes of mortality globally. Several studies have suggested that CVD risk can be predicted by an increase in aortic wave reflection. Thus, assessment of central hemodynamics could be an important clinical tool for not only predicting cardiovascular risk but also determining vascular health. Pulse Wave Analysis (PWA) is a common non-invasive measurement technique that can be used to evaluate aortic wave reflections. The SphygmoCor XCEL and VICORDER are two widely used devices that have a PWA function, but whether both devices generate comparable PWA outcomes is still unknown. The SphygmoCor XCEL is the current gold-standard device for PWA, but it is also expensive and requires extensive operator training, while the VICORDER is more cost-effective and easier to use. The agreement between the two devices would provide clinicians and researchers with multiple options to assess aortic wave reflection using PWA. In addition, since both devices are widely used, future researchers will be able to harmonize PWA data between the two devices across multiple studies. Therefore, the objective of this study is to compare and determine the agreement of PWA outcomes between the SphygmoCor XCEL and the VICORDER devices. Based on our results, we found that there is no meaningful agreement between the devices for PWA. The overall intraclass correlation (ICC) between devices for PWA outcomes were significantly below 0.9, which is our aim for a meaningful agreement. We suggest that future researchers and clinicians utilize the SphygmoCor XCEL as it is the current gold standard and most widely used device across multiple studies, rather than the VICORDER to assess aortic wave reflection indices and predict cardiovascular disease and health.

description: A $d$-dimensional framework is a pair $(G,p)$, where $G$ is a graph and $p$ maps the vertices of $G$ to points in $\mathbb{R}^d$. The edges of $G$ are mapped to the corresponding line segments. A graph $G$ is said to be globally rigid in $\mathbb{R}^d$ if every generic $d$-dimensional framework $(G,p)$ is determined, up to congruence, by its edge lengths. A finer property is global linkedness: we say that a vertex pair $\{u,v\}$ of $G$ is globally linked in $G$ in $\mathbb{R}^d$ if in every generic $d$-dimensional framework $(G,p)$ the distance of $u$ and $v$ is uniquely determined by the edge lengths.
 In this paper we investigate globally linked pairs in graphs in $\mathbb{R}^d$. We give several characterizations of those rigid graphs $G$ in which a pair $\{u,v\}$ is globally linked if and only if there exist $d+1$ internally disjoint paths from $u$ to $v$ in $G$. We call these graphs $d$-joined. Among others, we show that $G$ is $d$-joined if and only if for each pair of generic frameworks of $G$ with the same edge lengths, one can be obtained from the other by a sequence of partial reflections along hyperplanes determined by $d$-separators of $G$. We also show that the family of $d$-joined graphs is closed under edge addition, as well as under gluing along $d$ or more vertices. As a key ingredient to our main results, we prove that rigid graphs in $\mathbb{R}^d$ contain no crossing $d$-separators.
 Our results give rise to new families of graphs for which global linkedness (and global rigidity) in $\mathbb{R}^d$ can be tested in polynomial time.

description: We investigate a number of semantically defined fragments of Tarski's algebra of binary relations, including the function-preserving fragment. We address the question whether they are generated by a finite set of operations. We obtain several positive and negative results along these lines. Specifically, the homomorphism-safe fragment is finitely generated (both over finite and over arbitrary structures). The function-preserving fragment is not finitely generated (and, in fact, not expressible by any finite set of guarded second-order definable function-preserving operations). Similarly, the total-function-preserving fragment is not finitely generated (and, in fact, not expressible by any finite set of guarded second-order definable total-function-preserving operations). In contrast, the forward-looking function-preserving fragment is finitely generated by composition, intersection, antidomain, and preferential union. Similarly, the forward-and-backward-looking injective-function-preserving fragment is finitely generated by composition, intersection, antidomain, inverse, and an `injective union' operation.

description: Xerogel films were synthesized via sol-gel chemistry to fabricate optical nitroxyl (HNO) sensors. Selective detection of HNO in solution was achieved by monitoring the rates of manganese(III) meso-tetrakis(4-sulfonatophenyl) porphyrinate (MnIIITPPS) reductive nitrosylation in the anaerobic interior of aminoalkoxysilane-derived xerogel films. Nitroxyl permeability in sensor films deposited in round-bottom 96-well plates was enhanced via incorporation of trimethoxysilyl-terminated poly(amidoamine-organosilicon) (PAMAMOS) dendrimers in the xerogel network. The selectivity of MnIIITPPS for HNO, the overall sensitivity, and the working dynamic range of the resulting sensors were characterized. The HNO-sensing microtitre plates were used to quantify pH-dependent HNO generation by the recently described HNO-donor sodium-1-(isopropylamino)diazene-1-ium-1,2-diolate (IPA/NO), and compare HNO-production efficiency between IPA/NO and Angeli’s salt, a traditional HNO-donor.

description: This paper addresses structured normwise, mixed, and componentwise condition numbers (CNs) for a linear function of the solution to the generalized saddle point problem (GSPP). We present a general framework that enables us to measure the structured CNs of the individual components of the solution. Then, we derive their explicit formulae when the input matrices have symmetric, Toeplitz, or some general linear structures. In addition, compact formulae for the unstructured CNs are obtained, which recover previous results on CNs for GSPPs for specific choices of the linear function. Furthermore, applications of the derived structured CNs are provided to determine the structured CNs for the weighted Toeplitz regularized least-squares problems and Tikhonov regularization problems, which retrieves some previous studies in the literature.
