description: We report enhanced amplified spontaneous emission (ASE) and optical gain performance in a conjugated polymer (CP)-based thin film waveguide (WG) Si(100)/SiO2/poly[2-methoxy-5-(2′-ethylhexyloxy)-p-phenylene vinylene] (MEH-PPV) by encapsulating the active layer with a transparent dielectric film of poly(methyl methacrylate) (PMMA). With index matched SiO2 and PMMA claddings, symmetric WGs are formed that exhibit increased mode confinement and reduced propagation loss enabling lower ASE threshold (40%) and higher optical gain (50%) compared to Si(100)/SiO2/MEH-PPV/air asymmetric WGs. An extremely large net gain coefficient of 500 cm−1 is achieved under picosecond pulse excitation, which is >4× larger than values previously reported in the literature. Fabrication of symmetric WGs requires no complex processing techniques, thus offering a simple, low-cost approach for effectively controlling the ASE behavior of CP-based WGs and related optical devices.

description: The surface passivation of semiconductors on different surface orientations results in vastly disparate effects. Experiments of GaAs/poly(3,4-ethylenedioxythiophene/indium tin oxide solar cells show that sulfur passivation results in threefold conversion efficiency improvements for the GaAs (100) surface. In contrast, no improvements are observed after passivation of the GaAs (111B) surface, which achieves 4% conversion efficiency. This is explained by density-functional theory calculations, which find a surprisingly stable (100) surface reconstruction with As defects that contains midgap surface states. Band structure calculations with hybrid functionals of the defect surface show a surface state on the undimerized As atoms and its disappearance after passivation.

Gauge Invariance of Non-Abelian Field Strength Correlators: the Axial Gauge Puzzle

description: Many transport coefficients of the quark-gluon plasma and nuclear structure functions can be written as gauge invariant correlation functions of non-Abelian field strengths dressed with Wilson lines. We discuss the applicability of axial gauge $n\cdot A=0$ to calculate them. In particular, we address issues that appear when one attempts to trivialize the Wilson lines in the correlation functions by gauge-fixing. We find it is always impossible to completely remove the gauge fields $n\cdot A$ in Wilson lines that extend to infinity in the $n$-direction by means of gauge transformations. We show how the obstruction appears in an explicit example of a perturbative calculation, and we also explain it more generally from the perspective of the path integral that defines the theory. Our results explain why the two correlators that define the heavy quark and quarkonium transport coefficients, which are seemingly equal in axial gauge, are actually different physical quantities of the quark-gluon plasma and have different values. Furthermore, our findings provide insights into the difference between two inequivalent gluon parton distribution functions.

description: This paper is devoted to investigate the dynamics of the self gravitating adiabatic and anisotropic source in $5D$ Einstein Gauss-Bonnet gravity. To this end, the source has been taken as Tolman-Bondi model which preserve inhomogeneity in nature. The field equations, Misner-Sharp mass and dynamical equations have formulated in Einstein Gauss-Bonnet gravity in $5D$. The junction conditions have been explored between the anisotropic source and vacuum solution in Gauss-Bonnet gravity in detail. The Misner and Sharp approach has been applied to define the proper time and radial derivatives. Further, these helps to formulate general dynamical equations. The equations show that the mass of the collapsing system increases with the same amount as the effective radial pressure increases. The dynamical system preserve retardation which implies that system under-consideration goes to gravitational collapse.

description: At present, the planet faces a change in the composition and bioavailability of nutrients. Zinc deficiency is a widespread problem throughout the world. It is imperative to understand the mechanisms that organisms use to adapt to the deficiency of this micronutrient. In the Ascomycetes fungi, the ZIP family of proteins is one of the most important for zinc transport and includes high affinity Zrt1p and low zinc affinity Zrt2p transporters. After identification and characterization of ZRT1/ZRT2-like genes in Ustilago maydis we conclude that they encode for high and low zinc affinity transporters, with no apparent iron transport activity. These conclusions were supported by the gene deletion in Ustilago and the functional characterization of ZRT1/ZRT2-like genes by measuring the intracellular zinc content over a range of zinc availability. The functional complementation of the S. cerevisiae ZRT1Δ ZRT2Δ mutant with U. maydis genes supports this as well. U. maydis ZRT2 gene, was found to be regulated by pH through Rim101 pathway, thus providing novel insights into how this Basidiomycota fungus can adapt to different levels of Zn availability.

description: Austrothurgus cognatus (Smith), new combination
(Figs. 6–10)
 Lithurgus cognatus Smith, 1868: 255. Lectotype (new designation): NHML No. 17.a.2099; ♀, Champion Bay (Geraldton), Western Australia, Australia.
 DIAGNOSIS: The female of this species is similar to that of A. rubricatus in the sternal scopa and fifth and sixth terga with distal margins entirely covered with yellowish to light reddish brown setae (Fig. 6). It can be distinguished from that species by the following combination of characters: large bees (head width 4.8‒5.1 mm, body length 16‒17 mm); clypeus smooth, shiny, distinctly swollen laterally along epistomal sulcus (Figs. 6–8); vertex with large impunctate areas (Fig. 9); facial prominence with deep median emargination, appearing bilobed in dorsal view, projecting about 0.7 times width of compound eye in profile (Figs. 6–8); and mesoscutum and mesoscutellum smooth and shiny, with distinct transverse, irregular rugulae. The male also resembles that of A. rubricatus in the distal terga with light reddish brown setae on their discs contrasting with the remaining terga covered by dark brown to black setae. However, in A. cognatus the metabasitarsal carina is long, about as long as the distance from its superior margin to the base of the metabasitarsus (Fig. 10), whereas in A. rubricatus the metabasitarsal carina is much shorter than the distance between its superior margin and the base of the metabasitarsus (Fig. 5).
COMMENTS: This species was described based on both sexes. The female is more distinctive than the male and herein is designated as lectotype to stabilize the name. The label data for this specimen are as follow: Type // BM. TYPE HYM. 17.a.2099// Lithurgus cognatus Smith [handwritten, blue label] // W. Australia // Lectotype, Lithurgus cognatus Smith des. V.H.

On the universality of the Epstein zeta function

description: We study universality properties of the Epstein zeta function $E_n(L,s)$ for lattices $L$ of large dimension $n$ and suitable regions of complex numbers $s$. Our main result is that, as $n\to\infty$, $E_n(L,s)$ is universal in the right half of the critical strip as $L$ varies over all $n$-dimensional lattices $L$. The proof uses an approximation result for Dirichlet polynomials together with a recent result on the distribution of lengths of lattice vectors in a random lattice of large dimension and a strong uniform estimate for the error term in the generalized circle problem. Using the same approach we also prove that, as $n\to\infty$, $E_n(L_1,s)-E_n(L_2,s)$ is universal in the full half-plane to the right of the critical line as $(L_1,L_2)$ varies over all pairs of $n$-dimensional lattices. Finally, we prove a more classical universality result for $E_n(L,s)$ in the $s$-variable valid for almost all lattices $L$ of dimension $n$. As part of the proof we obtain a strong bound of $E_n(L,s)$ on the critical line that is subconvex for $n\geq 5$ and almost all $n$-dimensional lattices $L$.

description: We study the time evolution processes of non-Hermitian systems under the open boundary condition and confirm that the dynamical skin effect exists in non-Hermitian systems analytically, and unveil the mechanism of its formation, which is caused by both the non-Hermitian skin effect and the Hermitian wave packet spreading. Furthermore, we find that in contrast to the uniform speed motion in Hermitian situations, the Gaussian wave packet can be accelerated and amplified during its time evolution in non-Hermitian systems. This additional motion is found to be responsible for the dynamic skin effect.

On Lovelock analogues of the Riemann tensor

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: It is possible to define an analogue of the Riemann tensor for $N$th order Lovelock gravity, its characterizing property being that the trace of its Bianchi derivative yields the corresponding analogue of the Einstein tensor. Interestingly there exist two parallel but distinct such analogues and the main purpose of this note is to reconcile both these formulations. In addition we will show that any pure Lovelock vacuum in odd $d = 2N + 1$ dimensions is Lovelock flat, i.e. any vacuum solution of the theory has vanishing Lovelock-Riemann tensor. Further, in presence of cosmological constant it is the Lovelock-Weyl tensor that vanishes.

description: Microbial communities growing on the surfaces of standing dead stems of salt marsh grasses contribute to fixation of atmospheric nitrogen (N-2) in these N-limited intertidal systems. Salt marshes in North Carolina, USA, have been shown to exhibit N-2 fixation throughout the growth season, but the composition of these diazotrophic communities is poorly known. This study investigated the diversity of the epiphytic N-2-fixing microbial community on the surfaces of dead stems (shoots) of the cord grass Spartina alterniflora in a salt marsh in North Carolina. Sequencing of the nifH gene and microscopy showed that a diverse diazotrophic community consisting of at least 8 diazotrophic cyanobacterial taxa, as well as an assemblage of alpha-, gamma-, and delta-proteobacteria, was present. Half of the recovered unique nifH sequences fell into the cluster with anaerobes. N-2-fixation rates under natural irradiance ranged from 0.001 to 2.58 nmol C2H4 mu g chl a(-1) h(-1) (0.07 to 206 nmol C2H4 cm(-2) h(-1)) and decreased from spring to fall. Nitrogen-fixation rates had a positive relationship with chlorophyll a, suggesting phototrophs contributed to N-2 fixation. The dominant diazotrophs in this study differed from epiphytic communities described elsewhere in the southeast United States, suggesting regional differences are present in the diversity of these communities.
Probing sign structure using measurement-induced entanglement

description: The sign structure of quantum states is closely connected to quantum phases of matter, yet detecting such fine-grained properties of amplitudes is subtle. Here we employ as a diagnostic measurement-induced entanglement (MIE): the average entanglement generated between two parties after measuring the rest of the system. We propose that for a sign-free state, the MIE upon measuring in the sign-free basis decays no slower than correlations in the state before measurement. Concretely, we prove that MIE is upper bounded by mutual information for sign-free stabilizer states (essentially CSS codes), which establishes a bound between scaling dimensions of conformal field theories describing measurement-induced critical points in stabilizer systems. We also show that for sign-free qubit wavefunctions, MIE between two qubits is upper bounded by a simple two-point correlation function, and we verify our proposal in several critical ground states of one-dimensional systems, including the transverse field and tri-critical Ising models. In contrast, for states with sign structure, such bounds can be violated, as we illustrate in critical hybrid circuits involving both Haar or Clifford random unitaries and measurements, and gapless symmetry-protected topological states.

Microbial dynamics in autotrophic and heterotrophic seawater mesocosms. I. Effect of phytoplankton on the microbial loop

description: The effect of phytoplankton on the other compartments of a simple microbial loop consisting of dissolved matter, bacteria and nanoflagellates was investigated in three 1000 1 mesocosms. These mesocosms were inoculated with a natural bacterial community and (1) no other additions (No Addition tank), (2) Phaeocystis globosa (Phaeocystis tank), or (3) 2 diatom species (Diatom tank). During the 20 d experiment, autotrophic activity was negligible in the No Addition tank. In contrast a small P. globosa bloom developed in the Phaeocystis tank and a large diatom bloom dominated the Diatom tank. In this paper we describe the experiment, the changes in chlorophyll a and heterotrophic nanoflagellate concentrations, as well as the cycling of nitrogen, phosphorus, and silica. Then we provide a synthesis of the structure and functioning of the microbial loops in these 3 systems using cluster analysis, a statistical pattern recognition tool. The goal was to test the hypothesis that differences in the resident phytoplankton populations would be reflected in (1) the composition and concentration of dissolved organic matter, (2) the composition of the bacterial community, (3) the food web, and (4) the cycling of elements and organic matter. In all 3 mesocosms, nitrate and silicic acid remained abundant. Orthophosphate was preferred by diatoms, whereas Phaeocystis appeared to prefer dissolved organic phosphorus. The hypothesis that phytoplankton composition shapes the structure and functioning of the microbial loop was partially supported: 6 d after inoculation each mesocosm exhibited a distinct organic matter signature. After 10 to 12 d, concentrations of heterotrophic nanoflagellates were high enough to exert significant grazing pressure in all 3 mesocosms. A parallel shift in bacterial community composition was visible in all mesocosms at this time, possibly reflecting grazing pressure. The food-web structure developed divergently in the 3 mesocosms during the second half of the experiment. Differences in biochemical cycling between mesocosms were predominantly driven by the large quantitative differences in autotrophs.

description: A 20 d seawater mesocosm experiment was conducted to study microbial loop and carbon cycling dynamics in 3 experimental systems of different trophic status. Two mesocosms were supplemented with phytoplankton (Phaeocystis in one mesocosm and diatoms in another). This report details the variations in bacterial community composition and in carbon utilization potential investigated via assays measuring the hydrolysis of complex polysaccharides and a simple peptide compound. The first half of the study period was dominated by bacterial growth and large shifts in community composition coinciding with utilization of the organic carbon present at the beginning of the experiment, as shown by hydrolysis of specific polysaccharides and drawdown of labile dissolved organic carbon. During the second half of the experiment, bacterioplankton abundance, composition, and enzymatic activities changed in response to the experimental treatments. Multiple correlation analyses implicated co-variation between rRNA gene DGGE phylotypes (e.g. Alphaproteobacteria, Gammaproteobacteria, and Bacteroidetes) and specific combinations of environmental parameters and carbon resources, indicating phylotypic specialization to the experimental mesocosm conditions. Similarly, hydrolysis of 3 polysaccharides (xylan, chondroitin, and Isochrysis extract) correlated significantly with particular phylotypes, providing evidence of species-specific influences on carbon utilization that varied temporally over the experiment period. Aminopeptidase activity mirrored biomass accumulation, as indicated by positive correlations (>0.80) with most biomass indicators determined. These results illustrate that combined molecular and biochemical analysis of active microbial communities can illuminate linkages between specific organisms and important ecosystem processes such as carbon utilization. Additionally, our findings show that trophic status was reflected in community composition and carbon utilization activities.

Also, we prove a Lions and Lieb type results for $W^{s,G}\left(\mathbb{R}^{N}\right)$ that works together in a particular way to get a sequence whose the weak limit is nontrivial. As an application, we study the existence of solutions to Quasilinear elliptic problems in the whole space $\mathbb{R}^N$ involving the fractional $g-$Laplacian operator, where the conjugated function $\widetilde{G}$ of $G$ doesn't satisfy the $Δ_2$-condition.

description: The existence of barren plateaus has recently revealed new training challenges in quantum machine learning (QML). Uncovering the mechanisms behind barren plateaus is essential in understanding the scope of problems that QML can efficiently tackle. Barren plateaus have recently been shown to exist when learning global properties of random unitaries, which is relevant when learning black hole dynamics. Establishing whether local cost functions can circumvent these barren plateaus is pertinent if we hope to apply QML to quantum many-body systems. We prove a no-go theorem showing that local cost functions encounter barren plateaus in learning random unitary properties.

description: To investigate the evolution of syntax, we need to ascertain the evolutionary rôle of syntax and, before that, the very nature of syntax. Here, we will assume that syntax is computing. And then, since we are computationally Turing complete, we meet an evolutionary anomaly, the anomaly of sytax: we are syntactically too competent for syntax. Assuming that problem solving is computing, and realizing that the evolutionary advantage of Turing completeness is full problem solving and not syntactic proficiency, we explain the anomaly of syntax by postulating that syntax and problem solving co-evolved in humans towards Turing completeness. Examining the requirements that full problem solving impose on language, we find firstly that semantics is not sufficient and that syntax is necessary to represent problems. Our final conclusion is that full problem solving requires a functional semantics on an infinite tree-structured syntax. Besides these results, the introduction of Turing completeness and problem solving to explain the evolution of syntax should help us to fit the evolution of language within the evolution of cognition, giving us some new clues to understand the elusive relation between language and thinking.

Microbial dynamics in autotrophic and heterotrophic seawater mesocosms. III. Organic matter fluxes

description: We monitored the dynamics of extracellular organic matter in 3 mesocosms: one dominated by a heterotrophic (microbial) community with negligible autotrophic activity (net heterotrophic system), a second where a small Phaeocystis bloom developed (production and loss almost balanced), and a third harboring a large diatom bloom (net autotrophic system). In all mesocosms, meso- and macroscopic heterotrophic organisms were excluded to primarily study extracellular organic matter production and turnover by specific algae and microbial loop organisms, respectively. Concentration and composition of dissolved organic matter (DOM), i.e. dissolved organic carbon (DOC), monosaccharides and total carbohydrates (MCHO and TCHO), free and combined neutral carbohydrates (DFCHO and DCCHO), as well as free and combined amino acids (DFAA and DCAA) were measured. In addition, net and gross community production rates were determined to calculate C-budgets. Whereas concentrations and composition of MCHO differed very little among the 3 mesocosms, dynamics of TCHO, DFCHO, and DCCHO differed significantly. Concentrations of DFAA were higher in both algal mesocosms compared to the heterotrophic system, and composition of DFAA was significantly different in the Phaeocystis and Diatom tanks. The composition and concentration of DCAA, however, were similar in all 3 mesocosms. Total dissolved carbohydrates and amino acids comprised a substantial fraction of the DOC pool. Dynamics of these DOC fractions, however, could only partly explain those of DOC, implying either that other dissolved compounds were important for overall C-cycling, or that microbial degradation of DOM affects the detection of carbohydrates and protein components.

description: Open cloze questions have been attracting attention for both measuring the ability and facilitating the learning of L2 English learners. In spite of its benefits, the open cloze test has been introduced only sporadically on the educational front, largely because it is burdensome for teachers to manually create the questions. Unlike the more commonly used multiple choice questions (MCQ), open cloze questions are in free form and thus teachers have to ensure that only a ground truth answer and no additional words will be accepted in the blank. To help ease this burden, we developed CLOZER, an automatic open cloze question generator. In this work, we evaluate CLOZER through quantitative experiments on 1,600 answers and show statistically that it can successfully generate open cloze questions that only accept the ground truth answer. A comparative experiment with human-generated questions also reveals that CLOZER can generate OCQs better than the average non-native English teacher. Additionally, we conduct a field study at a local high school to clarify the benefits and hurdles when introducing CLOZER. The results demonstrate that while students found the application useful for their language learning. Finally, on the basis of our findings, we proposed several design improvements.

Planning healthy cities for immigrant populations

description: Austin is a rapidly growing city and an emerging gateway for immigrants. While Mexico is still the largest contributor of immigrants, there has been a gradual increase of immigrants from Asia and Africa as well. Austin is part of the welcoming communities movement that “seek to have long-time residents and recent immigrants work together to create stronger communities” (Wasem et al, 2021). The concept of healthy cities has existed for some time now – it attracts people to settle down in a place that provides for their wellbeing. However, what challenges arise for cities that are experiencing rapid demographic changes? In this report, the primary focus is the needs of a growing immigrant population in Austin. By examining the intersection of planning for healthy cities and the growing number of immigrants with specific needs, this report will explore the following research question: How do healthy city initiatives in Austin and in other cities consider and incorporate the specific needs of migrant communities? This population needs specific considerations at the beginning of their journey in a foreign land and even the years to come. We have yet to see this be a common topic discussed, although it has made headway in city departments. This report will investigate Austin’s healthy city initiatives and how they integrate the immigrant community. Austin falls into the category of developing cities with major population increases, including immigrants. I will include context on other cities’ experiences implementing healthy city initiatives to understand the lessons learned for Austin and vice versa. The purpose of this report is to recommend ways to incorporate the specific needs of immigrants into Austin’s healthy cities initiatives.
Trends in total Vibrio spp. and Vibrio vulnificus concentrations in the eutrophic Neuse River Estuary, North Carolina, during storm events

description: Vibrio spp. are ubiquitous members of aquatic microbial food webs that can be pathogenic to humans and a range of other organisms. Previously published predictive models for Vibrio spp. concentrations in estuarine and coastal waters, based only on salinity and temperature, are 70 to 75% accurate during 'normal' conditions (e.g. not during storms or drought). We have conducted a preliminary comparison of the output from this type of model to the natural concentrations of both total Vibrio spp. and the potentially pathogenic Vibrio vulnificus when measured during tropical storms. Water samples were collected in situ from a deployed platform in the Neuse River Estuary (NRE), North Carolina, USA, during 2 storm events: Hurricane Ophelia and Tropical Storm Ernesto. Total Vibrio spp. concentrations were measured using culture-based methods and V vulnificus levels were determined using a newly developed, rapid quantitative polymerase chain reaction (QPCR) assay. Results were analyzed in relation to environmental parameters and to concentrations of the fecal indicator bacteria Escherichia coli (EC) and Enterococcus spp. (ENT). Total concentrations of Vibrio spp. in the NRE were often orders of magnitude higher than those predicted by a previously published model. These large deviations from model predictions may indicate contributions from storm forcing (e.g. resuspension, surges) that are missing from the calm weather observations used to build these models.
Enhanced Li capacity in functionalized graphene: A first principle study with van der Waals correction

description: We have investigated the adsorption of Li on graphene oxide using density functional theory. We show a novel and simple approach to achieve a positive lithiation potential on epoxy and hydroxyl functionalized graphene, compared to the negative lithiation potential that has been found on prestine graphene. We included the van der Waals correction into the calculation so as to get better picture of weak interactions. A positive lithiation potential suggests a favorable adsorption of Li on graphene oxide sheets that can lead to an increase in the specific capacity, which in turn can be used as an anode material in Li-batteries. We find a high specific capacity of ~860 mAh/g by functionalizing the graphene sheet. This capacity is higher than the previously reported capacities that were achieved on graphene with high concentration of Stone-Wales (75%) and divacancy (16%) defects. Creating such high density of defects can make the entire system energetically unstable, whereas graphene oxide is a naturally occurring substance.
