description: This article proposes a topological method that extracts hierarchical structures of various amorphous solids. The method is based on the persistence diagram (PD), a mathematical tool for capturing shapes of multiscale data. The input to the PDs is given by an atomic configuration and the output is expressed as 2D histograms. Then, specific distributions such as curves and islands in the PDs identify meaningful shape characteristics of the atomic configuration. Although the method can be applied to a wide variety of disordered systems, it is applied here to silica glass, the Lennard-Jones system, and Cu-Zr metallic glass as standard examples of continuous random network and random packing structures. In silica glass, the method classified the atomic rings as short-range and medium-range orders and unveiled hierarchical ring structures among them. These detailed geometric characterizations clarified a real space origin of the first sharp diffraction peak and also indicated that PDs contain information on elastic response. Even in the Lennard-Jones system and Cu-Zr metallic glass, the hierarchical structures in the atomic configurations were derived in a similar way using PDs, although the glass structures and properties substantially differ from silica glass. These results suggest that the PDs provide a unified method that extracts greater depth of geometric information in amorphous solids than conventional methods.

description: We present status of the 3-3-1 models and their implications to cosmological evolution such as inflation, phase transitions and sphalerons. The models can deal not only with the issues such as neutrino physics, dark matter, etc, but they are also able to provide quite good agreement with the Standard Cosmology: the inflation happens at the GUT scale, while phase transition has two sequences corresponding two steps of symmetry breaking in the models, namely: SU(3) --> SU(2) and SU(2) --> U(1). Some bounds on the model parameters are obtained: in the RM331, the mass of the heavy neutral Higgs boson is fixed in the range: 285.56 GeV

description: We investigate spt-crank-type functions arising from Bailey pairs. We recall four spt-type functions corresponding to the Bailey pairs $A1$, $A3$, $A5$, and $A7$ of Slater and given four new spt-type functions corresponding to Bailey pairs $C1$, $C5$, $E2$, and $E4$. Each of these functions can be thought of as a count on the number of appearances of the smallest part in certain integer partitions. We prove simple Ramanujan type congruences for these functions that are explained by a spt-crank-type function. The spt-crank-type functions are two variable $q$-series determined by a Bailey pair, that when $z=1$ reduce to the spt-type functions. We find the spt-crank-type functions to have interesting representations as either infinite products or as Hecke-Rogers-type double series. These series reduce nicely when $z$ is a certain root of unity and allow us to deduce the congruences. Additionally we find dissections when $z$ is a certain root of unity to give another proof of the congruences. Our double sum and product formulas require Bailey's Lemma and conjugate Bailey pairs. Our dissection formulas follow from Bailey's Lemma and dissections of known ranks and cranks.

description: SOX5 encodes a transcription factor involved in the regulation of chondrogenesis and the development of the nervous system. Despite its important developmental roles, SOX5 disruption has yet to be associated with human disease. We report one individual with a reciprocal translocation breakpoint within SOX5, eight individuals with intragenic SOX5 deletions (four are apparently de novo and one inherited from an affected parent), and seven individuals with larger 12p12 deletions encompassing SOX5. Common features in these subjects include prominent speech delay, intellectual disability, behavior abnormalities, and dysmorphic features. The phenotypic impact of the deletions may depend on the location of the deletion and consequently which of the three major SOX5 protein isoforms are affected. One intragenic deletion involving only untranslated exons was present in a more mildly affected subject, was inherited from a healthy parent and grandparent, and is similar to a deletion found in a control cohort. Therefore, some intragenic SOX5 deletions may have minimal phenotypic effect. Based on the location of the deletions in the subjects compared to the controls, the de novo nature of most of these deletions, and the phenotypic similarities among cases, SOX5 appears to be a dosage-sensitive, developmentally important gene.

description: Many techniques for measuring neutron star radii rely on absolute flux measurements in the X-rays. As a result, one of the fundamental uncertainties in these spectroscopic measurements arises from the absolute flux calibrations of the detectors being used. Using the stable X-ray burster, GS 1826-238, and its simultaneous observations by Chandra HETG/ACIS-S and RXTE/PCA as well as by XMM-Newton EPIC-pn and RXTE/PCA, we quantify the degree of uncertainty in the flux calibration by assessing the differences between the measured fluxes during bursts. We find that the RXTE/PCA and the Chandra gratings measurements agree with each other within their formal uncertainties, increasing our confidence in these flux measurements. In contrast, XMM-Newton EPIC-pn measures 14.0$\pm$0.3 % less flux than the RXTE/PCA. This is consistent with the previously reported discrepancy with the flux measurements of EPIC-pn, compared to EPIC-MOS1, MOS2 and ACIS-S detectors. We also show that any intrinsic time dependent systematic uncertainty that may exist in the calibration of the satellites has already been implicity taken into account in the neutron star radius measurements.

description: Neurofibromatosis type 1 (NF1) is one of the most frequent genetic disorders, affecting 1:3,000 worldwide. Identification of genotype–phenotype correlations is challenging because of the wide range clinical variability, the progressive nature of the disorder, and extreme diversity of the mutational spectrum. We report 136 individuals with a distinct phenotype carrying one of five different NF1 missense mutations affecting p.Arg1809. Patients presented with multiple café‐au‐lait macules (CALM) with or without freckling and Lisch nodules, but no externally visible plexiform neurofibromas or clear cutaneous neurofibromas were found. About 25% of the individuals had Noonan‐like features. Pulmonic stenosis and short stature were significantly more prevalent compared with classic cohorts (P < 0.0001). Developmental delays and/or learning disabilities were reported in over 50% of patients. Melanocytes cultured from a CALM in a segmental NF1‐patient showed two different somatic NF1 mutations, p.Arg1809Cys and a multi‐exon deletion, providing genetic evidence that p.Arg1809Cys is a loss‐of‐function mutation in the melanocytes and causes a pigmentary phenotype. Constitutional missense mutations at p.Arg1809 affect 1.23% of unrelated NF1 probands in the UAB cohort, therefore this specific NF1 genotype–phenotype correlation will affect counseling and management of a significant number of patients.

description: We investigate how material rigidity acts as a key control parameter for the failure of solids under stress. In both experiments and simulations, we demonstrate that material failure can be continuously tuned by varying the underlying rigidity of the material while holding the amount of disorder constant. As the rigidity transition is approached, failure due to the application of uniaxial stress evolves from brittle cracking to system-spanning diffuse breaking. This evolution in failure behavior can be parameterized by the width of the crack. As a system becomes more and more floppy, this crack width increases until it saturates at the system size. Thus, the spatial extent of the failure zone can be used as a direct probe for material rigidity.

Food-Sharing Networks in Lamalera, Indonesia: Reciprocity, Kinship, and Distance

Year: 2010

description: Exponential random graph modeling (ERGM) is used here to test hypotheses derived from human behavioral ecology about the adaptive nature of human food sharing. Respondents in all (n=317) households in the fishing and sea-hunting village of Lamalera, Indonesia were asked to name those households to whom they had more frequently given (and from whom they had more frequently received) food during the preceding sea-hunting season. The responses were used to construct a social network of between-household food-sharing relationships in the village. The results show that kinship, proximity, and reciprocal sharing all strongly increase the probability of giving food to a household. The effects of kinship and distance are relatively independent of each other, while reciprocity is more common among residentially and genealogically close households. The results show support for reciprocal altruism as a motivation for food sharing while kinship and distance appear to be important partner-choice criteria.

description: The drivers of insect radiation in mountain ecosystems are poorly understood compared to birds and plants. We studied the rapid radiation of the butterfly genus Colias, which has diversified in mountain ecosystems in Eurasia, Africa, and the Americas. Based on a dataset of 150 nuclear protein-coding genetic loci and whole mitochondrial genomes, we constructed a time-calibrated tree of the genus Colias with broad taxon sampling. We then inferred historical characteristics of this genus, including ancestral range reconstruction, historical diversification rates, and the evolution of host plant use. Coupled with historical climatic and geological events, we investigated the factors that influenced rapid diversification of the genus Colias. The initial burst of Colias diversification originated in South America at ~2.75 Ma, followed by a gradual decline in the diversification rate to the present. We found that rapid diversification was driven by several factors including favorably warm climates in the mid-Pliocene that promoted the population expansion, and the formation of the Isthmus of Panama and the Bering Land Bridge, which led to intercontinental dispersals that opened new ecological opportunities. These two extrinsic factors may simultaneously be the main extrinsic drivers of the genus' rapid diversification. Introgression may have improved the ecological adaptability of the genus Colias, and we propose that this is the primary intrinsic driver of diversification. Expansion of host plant breadth enabling population expansion was a secondary driving factor. We suggest that mountain uplift had little effect on the diversity of Colias after the initial split from the common ancestor shared with its sister taxon Zerene and emphasize the importance of historical climatic and geological events for studies of rapid radiations of montane species.

Kin Preference and Partner Choice: Patrilineal Descent and Biological Kinship in Lamaleran Cooperative Relationships
Creators: name: Nolin, David A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: This paper presents a comparison of social kinship (patrilineage) and biological kinship (genetic relatedness) in predicting cooperative relationships in two different economic contexts in the fishing and whaling village of Lamalera, Indonesia. A previous analysis of boat crew affiliation data collected in the village in 1999 found that social kinship (patrilineage) was a better predictor of crew affiliation than was genetic kinship. A replication of this analysis using similar data collected in 2006 finds the same pattern: lineage is a better predictor than genetic kinship of crew affiliation, and the two together explain little additional variance over that explained by lineage alone. However, an analogous test on food-sharing relationships finds the opposite pattern: biological kinship is a better predictor of food-sharing relationships than is social kinship. The difference between these two cooperative contexts is interpreted in terms of kin preferences that shape partner choice, and the relative autonomy with which individuals can seek to satisfy those preferences. Drawing on stable matching theory, it is suggested that unilineal descent may serve as a stable compromise among multiple individuals’ incongruent partner preferences, with patriliny favored over matriliny in the crew-formation context because it leads to higher mean degrees of relatedness among male cooperators. In the context of food-sharing, kin preferences can be pursued relatively autonomously, without the necessity of coordinating preferences with those of other households through the institution of lineage.

description: This paper brings together over two decades of research concerning the patterns and processes of livelihood diversification through migration among Maasai pastoralists and agro-pastoralists of northern Tanzania. Two case studies, one from the Ngorongoro Conservation Area and the other from the Simanjiro plains, jointly demonstrate the complexity of migration within a single ethnic group. We analyze the relationship between wealth and migration and examine some of the consequences of migration for building herds, expanding cultivation, and influencing political leadership. We further argue that migration in Maasai communities is becoming a cultural norm and not only a response to economic conditions.

description: In this work, we describe a method to realize 3D Weyl semimetal by coupling multilayers of honeycomb optical lattice in the presence of a pair of Raman lasers. The Raman lasers render each isolated honeycomb layer a Chern insulator. With finite interlayer coupling, the bulk gap of the system closes at certain out-of-plane momenta due to Raman assisted tunnelling and result in the Weyl semimetal phase. Using experimentally relevant parameters, we show that both one and two pairs of Weyl points can be realized by tuning the interlayer coupling strength. We suggest that Landau-Zener tunnelling can be used to detect Weyl points and show that the transition probability increases dramatically when Weyl point emerges. The realization of chiral anomaly by using a magnetic field gradient is also discussed.

description: Mantle cell lymphoma (MCL) and chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) share many features and both arise from CD5+ B-cells, their distinction is critical as MCL is a much more aggressive neoplasm. Rarely, composite MCL and CLL/SLL have been reported. Little is known, about the nature of these cases and in particular the clonal relationship of the two lymphomas. Eleven composite MCL and CLL/SLL cases were identified. The clinical, morphologic and immunophenotypic features of the MCL and CLL/SLL were characterized. Immunoglobulin heavy chain (IGH) gene analysis was performed on microdissected MCL and CLL/SLL components to assess their clonal relationship. Ten patients had lymphadenopathy, and 7 patients had bone marrow involvement. The MCL component had the following growth patterns: in situ (n=1), mantle zone (n=3), nodular and diffuse (n=3), diffuse (n=3), and interstitial in the bone marrow (the only patient without lymphadenopathy) (n=1); 6 MCL had blastoid or pleomorphic and 5 classical cytologic features. The CLL/SLL component was internodular (n=9) or diffuse (n=2). All MCL were CD5+ and cyclin D1+ with t(11;14) translocation. All CLL/SLL were CD5+, CD23+ and negative for cyclin D1 or t(11;14). IGH gene analysis showed that the MCL and CLL/SLL components displayed different sized fragments, indicating that the MCL and CLL/SLL are likely derived from different neoplastic B-cell clones. The lack of a clonal relationship between the MCL and CLL/SLL components suggests that the MCL and CLL/SLL represent distinct disease processes and do not share a common progenitor B-cell.

description: Significance of signet ring cells in mucinous adenocarcinoma of the peritoneum from appendiceal origin has never been specifically studied. We retrospectively reviewed cases of mucinous adenocarcinoma of the peritoneum from appendiceal origin (n = 55) and collected clinical follow-up data. Signet ring cells were identified in 29 of 55 cases. No low-grade mucinous adenocarcinoma case (n = 11) had signet ring cells, whereas 29 of 44 high-grade mucinous adenocarcinoma cases did. Cases of high-grade mucinous adenocarcinoma were subdivided into 3 groups: (1) high-grade mucinous adenocarcinoma without signet ring cells (n = 15), (2) high-grade mucinous adenocarcinoma with signet ring cells only within mucin pools (n = 20), and (3) high-grade mucinous adenocarcinoma with signet ring cells invading tissue (n = 9). Overall survival (OS) and progression-free survival were subsequently evaluated. Five-year OS for cases of high-grade mucinous adenocarcinoma without signet ring cells and high-grade mucinous adenocarcinoma with signet ring cells within mucin pools were similar at 31.8% (SE, 14.4%) and 35.8% (SE, 13.9%), respectively. A significant survival difference was seen for cases of high-grade mucinous adenocarcinoma with signet ring cells invading tissue with a median OS of 0.5 years versus 2.9 and 2.4 years (P = .04 and P = .03), respectively, for cases of high-grade mucinous adenocarcinoma without signet ring cells and high-grade mucinous adenocarcinoma with signet ring cells within mucin pools. Finding signet ring cells floating in extracellular mucin pools made no prognostic difference when compared with cases of high-grade mucinous adenocarcinoma without signet ring cells. In contrast, high-grade mucinous adenocarcinoma with signet ring cells invading tissue was significant for worse survival, and thus, we propose reporting signet ring cell tissue invasion particularly when extensive.

Given a faithful Galois extension $A \to B$ of ring spectra, we consider whether the map $THH(A) \otimes_A B \to THH(B)$ is an equivalence. We reprove and extend positive results of Weibel-Geller and McCarthy-Minasian and offer new examples of Galois extensions for which base-change holds. We also provide a counterexample where base-change fails.

description: The androgen receptor (AR) is a ligand-activated transcription factor of the male and female reproductive tracts whose activity is modulated by coregulator binding. We recently identified melanoma antigen gene protein-11 (MAGE-11) of the MAGEA gene family that functions as an AR coregulator by binding the AR N-terminal FXXLF motif. Here we report that MAGE-11 is expressed in a temporal fashion in endometrium of normally cycling women. Highest levels of MAGE-11 mRNA and protein occur in the mid-secretory stage, coincident with the window of uterine receptivity to embryo implantation. Studies in human endometrial cell lines together with the hormone profile of the menstrual cycle and pattern of estrogen receptor-α expression in cycling endometrium suggest the rise in MAGE-11 mRNA results from down-regulation by estradiol during the proliferative phase and up-regulation by cyclic AMP signaling in the early and mid-secretory stage. In agreement with its coregulatory function, MAGE-11 localizes with AR in glandular epithelial cell nuclei in the mid-secretory stage. The increase in AR protein in the mid-secretory endometrium without an increase in AR mRNA suggests MAGE-11 stabilizes AR in glandular epithelial cell nuclei. This was supported by expression studies at low androgen levels indicating AR stabilization by MAGE-11 dependent on the AR N-terminal transactivation domain. The results suggest that MAGE-11 functions as a coregulator that increases AR transcriptional activity during the establishment of uterine receptivity in the human female.

In contrast to previous such results, it is not assumed that the underlying process has absolutely continuous laws. Moreover, governing equations in the backward variables are derived. Three examples of anomalous diffusion processes illustrate the theory.

description: We describe experiments and simulations demonstrating the propulsion of a neutrally-buoyant swimmer that consists of a pair of spheres attached by a spring, immersed in a vibrating fluid. The vibration of the fluid induces relative motion of the spheres which, for sufficiently large amplitudes, can lead to motion of the center of mass of the two spheres. We find that the swimming speed obtained from both experiment and simulation agree and collapse onto a single curve if plotted as a function of the streaming Reynolds number, suggesting that the propulsion is related to streaming flows. There appears to be a critical onset value of the streaming Reynolds number for swimming to occur. We observe a change in the streaming flows as the Reynolds number increases, from that generated by two independent oscillating spheres to a collective flow pattern around the swimmer as a whole. The mechanism for swimming is traced to a strengthening of a jet of fluid in the wake of the swimmer.

title: Using a choice experiment with insights from laddering technique to reveal consumer preferences towards the acceptance of functional foods
Creators: name: Bitzios, Michail
Publisher: name: University of Kent
Year: 2022

description: This research brings together, into one powerful analytical tool, two methodologies, Laddering Technique (L.T.) and Choice Experiment (C.E.), which complement each other nicely, in an 'attempt to examine consumers buying motives in relation to bread. The incentive to explore consumers' "black box" was given by the fact that changes in relation to nutritional issues have become apparent. The case of bread, particularly, attracts the attention of research as a product widely consumed that, however, has not been given much attention by researchers. L.T. approaches the subject from the psychological point of view and explores how people relate products with their personal values. L.T. was implemented so as to gain richer understanding as to how people translate product's characteristics into indicative connotation with respect to themselves. It has also created the basis for the second part of research by informing the attributes used in the C.E. The data was generated with the use of questionnaire that was completed by a small sample of individuals. The results revealed that bread type and the perceived bread healthiness are among the most important aspects consumers consider when buying bread. C.E. was used to examine how the inclusion of a functional ingredient affects consumer attitudes towards bread. An important feature of the C;E. design was the inclusion of the Dutch Eating Behavioural Ouestionnaire (D.E.B.O.) to collect information on participants underlying eating behaviours. The survey instrument employed a single postal mail shot. The results showed - again - that bread type is a major factor in determining choice and that the inclusion of a functional ingredient returned relatively small measures of value. The estimation of a Latent Class Model (L.C.M.) revealed differences in W.T.P. between segments. Also, segment membership can be partly explained by the D.E.B.O. Finally, an important finding is that respondents hold a stronger preference for a simple health statement compared or in addition to the benefits resulting from consuming a product that includes functional ingredients.

description: Rosacea is a chronic inflammatory dermatosis characterized by erythema, papules, pustules, and telangiectasia in the central facial region, without comedones. Its etiology is unknown, although alterations in vascular structure, connective tissue, and immune response to microorganisms such as Demodex folliculorum or Helicobacter pylori have been implicated as key pathogenic mechanisms. Therapeutic options do not target the underlying pathogenic mechanisms and are not curative due to the ongoing uncertainty surrounding the exact pathophysiology. Treatment is based on the use of topical or systemic antibiotics, anti-inflammatory agents, and retinoids.

description: The latest Gaia data releases (EDR3 and, soon, DR3) have greatly facilitated the identification and investigation of members of nearby young moving groups (NYMGs), here defined as groups of stars of age <150 Myr within ~120 pc. Among the known NYMGs, the youngest and closest is the \(\epsilon\) Chameleonis Association (eCA), with an age ~5 Myr and distance of ~100 pc (D. Annie Dickson-Vandervelde et al. 2021, AJ, 161, 87). Thanks to its age and proximity, the eCA represents a prime subject for the study of pre-main sequence stellar evolution and evolved protoplanetary disks. Using EDR3, we have amassed over 90 new eCA candidates. We analyze the spatio-kinematics of the new members, showing consistency with the eCA's ~50+ previously known bona fide and candidate members. We fit Gaia, 2MASS, and WISE photometry for the new candidates, to model atmospheres to determine effective temperatures and luminosities. This spectral typing exercise reveals that the new candidates are mainly cool M-type stars; we also identify a handful of candidate (proto) brown dwarfs. Isochronal fitting yields age estimates that are also generally consistent with eCA membership. Future work will incorporate radial velocities from DR3 as well as ground-based spectroscopy to determine radial velocities and Li absorption line equivalent widths, so as to further bolster eCA membership and understand the spatio-kinematic relationship between the eCA and the Lower Centaurus Crux, its (somewhat older) neighbor NYMG.

description: We have used time-of-flight inelastic neutron scattering to measure the spin wave spectrum of the canonical half-doped manganite Pr$_{0.5}$Ca$_{0.5}$MnO$_{3}$, in its magnetic and orbitally ordered phase. The data, which cover multiple Brillouin zones and the entire energy range of the excitations, are compared with several different models that are all consistent with the CE-type magnetic order, but arise through different exchange coupling schemes. The Goodenough model, i.e. an ordered state comprising strong nearest neighbor ferromagnetic interactions along zig-zag chains with antiferromagnetic inter-chain coupling, provides the best description of the data, provided that further neighbor interactions along the chains are included. We are able to rule out a coupling scheme involving formation of strongly bound ferromagnetic dimers, i.e. Zener polarons, on the basis of gross features of the observed spin wave spectrum. A model with weaker dimerization reproduces the observed dispersion but can be ruled out on the basis of discrepancies between the calculated and observed structure factors at certain positions in reciprocal space. Adding further neighbor interactions results in almost no dimerization, i.e. recovery of the Goodenough model. These results are consistent with theoretical analysis of the degenerate double exchange model for half-doping, and provide a recipe for how to interpret future measurements away from half-doping, where degenerate double exchange models predict more complex ground states.

description: To a natural number $n$, a finite partially ordered set $P$ and a poset ideal ${\mathcal J}$ in the poset $Hom(P,[n])$ of isotonian maps from $P$ to the chain on $n$ elements, we associate two monomial ideals, the letterplace ideal $L(n,P;{\mathcal J})$ and the co-letterplace ideal $L(P,n;{\mathcal J})$. These ideals give a unified understanding of a number of ideals studied in monomial ideal theory in recent years. By cutting down these ideals by regular sequences of variable differences we obtain: multichain ideals and generalized Hibi type ideals, initial ideals of determinantal ideals, strongly stable ideals, $d$-partite $d$-uniform ideals, Ferrers ideals, edge ideals of cointerval $d$-hypergraphs, and uniform face ideals.

Occurrence rates of terrestrial planets orbiting mid-to-late M dwarfs from TESS Sectors 1-42

description: We analyze a volume-complete sample of 365 mid-to-late M dwarfs within 15 pc with masses between 0.1 and 0.3 MSun observed by TESS within Sectors 1 to 42. The median mass of the stars in this sample is 0.17 MSun. We search the TESS 2-minute cadence light curves for transiting planets with orbital periods below 7 days using a modified Box-Least Squares algorithm and recover all 6 known planets as well as a likely planet candidate orbiting LHS 475. We further perform a transit injection and recovery analysis to characterize the sensitivity as a function of planet radius, insolation, and orbital period. We find a median sensitivity above 70% for transiting planets with orbital periods below 1 day and radii above 0.6 REarth; we also find a median sensitivity near unity for any planet with a radius of at least 1 REarth up to an orbital period of 7 days. We estimate an occurrence rate of 0.61 [0.42, 0.85] planets per M dwarf for periods below 7 days. We find that in contrast to heavier stars, the close-in planet population around the smallest M dwarfs is heavily lopsided towards terrestrial planets, which outnumber sub-Neptunes at a ratio of 14 to 1. This discrepancy persists even when accounting for the total incident flux the planets receive from the host star.

Average-Value Tverberg Partitions via Finite Fourier Analysis

description: The long-standing topological Tverberg conjecture claimed, for any continuous map from the boundary of an $N(q,d):=(q-1)(d+1)$-simplex to $d$-dimensional Euclidian space, the existence of $q$ pairwise disjoint subfaces whose images have non-empty $q$-fold intersection. The affine cases, true for all $q$, constitute Tverberg's famous 1966 generalization of the classical Radon's Theorem. Although established for all prime powers in 1987 by Özaydin, counterexamples to the conjecture, relying on 2014 work of Mabillard and Wagner, were first shown to exist for all non-prime-powers in 2015 by Frick. Starting with a reformulation of the topological Tverberg conjecture in terms of harmonic analysis on finite groups, we show that despite the failure of the conjecture, continuous maps \textit{below} the tight dimension $N(q,d)$ are nonetheless guaranteed $q$ pairwise disjoint subfaces -- including when $q$ is not a prime power -- which satisfy a variety of "average value" coincidences, the latter obtained as the vanishing of prescribed Fourier transforms.

description: Pregnancy is dependent upon the endometrium acquiring a receptive phenotype that facilitates apposition, adhesion and invasion of a developmentally competent embryo. Surface-enhanced laser desorption/ionization time-of-flight mass spectrometry of mid-secretory endometrial biopsies revealed a 28 kDa protein peak that discriminated highly between samples obtained from women with recurrent implantation failure and fertile controls. Subsequent tandem mass spectroscopy unambiguously identified this peak as apolipoprotein A-I (apoA-I), a potent anti-inflammatory molecule. Total endometrial apoA-I levels were, however, comparable between the study and control group. Moreover, endometrial apoA-I mRNA expression was not cycle-dependent although there was partial loss of apoA-I immunoreactivity in luminal and glandular epithelium in mid-secretory compared with proliferative endometrial samples. Because of its putative anti-implantation properties, we examined whether endometrial apoA-I expression is regulated by embryonic signals. Human chorionic gonadotrophin (hCG) strongly inhibited apoA-I expression in differentiating explant cultures but not when established from eutopic endometrium from patients with endometriosis. Pelvic endometriosis was associated with elevated apoA-I mRNA levels, increased secretion by differentiating eutopic endometrial explant cultures and lack of hCG-dependent down-regulation. To corroborate these observations, we examined endometrial apoA-I expression and its regulation by hCG in a non-human primate model of endometriosis. As in humans, hCG strongly inhibited endometrial apoA-I mRNA expression in disease-free baboons, but this response was entirely lost upon induction of pelvic endometriosis. Together, these observations indicate that perturbations in endometrial apoA-I expression, modification or regulation by paracrine embryonic signals play a major role in implantation failure and infertility.
Reducibility of Matrix Weights

description: In this paper we discuss the notion of reducibility for matrix weights and introduce a real vector space $\mathcal C_\mathbb{R}$ which encodes all information about the reducibility of $W$. In particular a weight $W$ reduces if and only if there is a non-scalar matrix $T$ such that $TW=WT^*$. Also, we prove that reducibility can be studied by looking at the commutant of the monic orthogonal polynomials or by looking at the coefficients of the corresponding three term recursion relation. A matrix weight may not be expressible as direct sum of irreducible weights, but it is always equivalent to a direct sum of irreducible weights. We also establish that the decompositions of two equivalent weights as sums of irreducible weights have the same number of terms and that, up to a permutation, they are equivalent. We consider the algebra of right-hand-side matrix differential operators $\mathcal D(W)$ of a reducible weight $W$, giving its general structure. Finally, we make a change of emphasis by considering reducibility of polynomials, instead of reducibility of matrix weights.
