Year: 2001

description: A new Nerillidae, Xenonerilla bactericola, new genus and species, is described from the dysoxic Santa Barbara
 Basin, off southern California, USA. Common occurrence of the species is restricted to sediments laden with mats of
 filamentous sulphide-oxidizing bacteria. The body comprises a small prostomium and nine segments; the last is fused with
 the pygidium. The head has two large, ventrolateral palps, antennae are absent. The first segment (buccal segment) has
 neither parapodia nor chaetae. Segments II to IX possess parapodial cirri of similar size. Thin capillary chaetae are restricted
 to posterior segments, only one-two ventral chaetae exist per parapodium. Two pear-shaped anal cirri are present. Distinct
 characters that separate the new taxon from all hitherto known nerillids are: (1) most specimens completely lack chaetae,
 while others have only very few chaetae, (2) in the pharyngeal organ, the bulbous muscle is covered anteriorly by an
 eversible epithelial part. This ventrally located tongue contains intracellular buccal pieces. A brief summary of the 16 known
 genera of Nerillidae is presented in a tabular form.

description: Chromosomes move toward mitotic spindle poles by a Pacman-flux mechanism linked to microtubule depolymerization: chromosomes actively depolymerize attached microtubule plus ends (Pacman) while being reeled in to spindle poles by the continual poleward flow of tubulin subunits driven by minus-end depolymerization (flux). We report that Pacman-flux in Drosophila melanogaster incorporates the activities of three different microtubule severing enzymes, Spastin, Fidgetin, and Katanin. Spastin and Fidgetin are utilized to stimulate microtubule minus-end depolymerization and flux. Both proteins concentrate at centrosomes, where they catalyze the turnover of γ-tubulin, consistent with the hypothesis that they exert their influence by releasing stabilizing γ-tubulin ring complexes from minus ends. In contrast, Katanin appears to function primarily on anaphase chromosomes, where it stimulates microtubule plus-end depolymerization and Pacman-based chromatid motility. Collectively, these findings reveal novel and significant roles for microtubule severing within the spindle and broaden our understanding of the molecular machinery used to move chromosomes.

On the genus Coelocalypta (Porifera: Demospongiae) and other related fistulose halichondrid genera.
Creators: name: CARBALLO, José Luis

Year: 2001

description: Coelocalypta is a fistulose halichondrid genus very close to others like Ciocalypta and Collocalypta. The genus
 has been synonymyzed and the species hitherto known as Coelocalypta porrecta, C. aderma and C. hyaline were transferred
 to other genera by some authors. However, after examination of several specimens of Coelocalypta porrecta from the Gulf
 of Cadiz and type material from the species Coelocalypta porrecta, Coelocalypta aderma, Ciocalypta penicillus, Ciocalypta
 microstrongylata and Collocalypta digitata, we propose the validity of these genera based on 1.- the ectosomal skeleton of
 the fistule: tangential in Ciocalypta, palisade-like in Coelocalypta, and absent in Collocalypta; 2.- the skeletal arrangement
 in the basal mass of the body: halichondroid-confused in Ciocalypta/Coelocalypta and plumose in Collocalypta; 3.- the
 presence of a tangential ectosomal skeleton in the basal mass in Ciocalypta, absent in Coelocalypta/Collocalypta. In this
 way, the genus Coelocalypta would include the species Coelocalypta porrecta which is here redescribed on the basis of SEM
 observation of new material, as well as Coelocalypta microstrongylata n. comb. Moreover, the new genus
 Pseudohymeniacidon is proposed to include the species Coelocalypta aderma.

In dem rechtlich kodifizierten und strukturell-funktionellen Rahmen innerhalb des Systems der beruflichen Bildung stellen formale Abstimmungen zur Sicherstellung organisatorisch-administrativer Abläufe durchaus den "Normalfall" dar. "Nicht-Kooperation" zumindest zwischen den Institutionen unterschiedlichen institutionellen Typus kann daher gerade als Zeichen des "reibungslos" funktionierenden Systems der beruflichen Bildung in Deutschland betrachtet werden.

description: Blood vessel formation requires the integrated regulation of endothelial cell proliferation and branching morphogenesis, but how this coordinated regulation is achieved is not well understood. Flt-1 (vascular endothelial growth factor [VEGF] receptor 1) is a high affinity VEGF-A receptor whose loss leads to vessel overgrowth and dysmorphogenesis. We examined the ability of Flt-1 isoform transgenes to rescue the vascular development of embryonic stem cell–derived flt-1−/− mutant vessels. Endothelial proliferation was equivalently rescued by both soluble (sFlt-1) and membrane-tethered (mFlt-1) isoforms, but only sFlt-1 rescued vessel branching. Flk-1 Tyr-1173 phosphorylation was increased in flt-1−/− mutant vessels and partially rescued by the Flt-1 isoform transgenes. sFlt-1–rescued vessels exhibited more heterogeneous levels of pFlk than did mFlt-1–rescued vessels, and reporter gene expression from the flt-1 locus was also heterogeneous in developing vessels. Our data support a model whereby sFlt-1 protein is more efficient than mFlt-1 at amplifying initial expression differences, and these amplified differences set up local discontinuities in VEGF-A ligand availability that are important for proper vessel branching.
Dynamic Health System Performance Forecasting through Cross-Platform Business Analytics and Federated Clinical Data Integration

description: Health systems worldwide are under increasing pressure to deliver efficient, high-quality care in an environment marked by operational complexity and fragmented data infrastructures. At a macro level, the integration of business intelligence (BI) platforms with federated clinical data offers an innovative pathway to dynamically forecast healthcare system performance. By connecting disparate sources across hospitals, outpatient centers, and digital health tools, organizations can move toward a unified, predictive model for evaluating capacity, care quality, and financial health. This paper examines how dynamic forecasting models powered by cross-platform BI and federated data architectures enhance decision-making and operational resilience. Using a combination of time-series analytics, machine learning algorithms, and real-time performance dashboards, these systems provide insights into patient flow, staff utilization, treatment outcomes, and reimbursement efficiency. Federated learning ensures data privacy by enabling model training without centralized data aggregation, thereby protecting sensitive clinical information while still enabling robust analytics. Narrowing the focus, the paper investigates use cases such as predicting ICU demand, surgical throughput, and emergency department congestion. It highlights how these forecasting tools can identify early signs of system strain, allowing health administrators to implement timely corrective actions and reallocate resources. Furthermore, this approach supports strategic planning, contract negotiations with payers, and compliance with regulatory benchmarks. The study concludes with a roadmap for implementing performance forecasting systems across institutions, emphasizing interoperability, data governance, and staff training. This integration represents a paradigm shift toward anticipatory governance in healthcare, where performance metrics evolve in real-time to guide both clinical and administrative strategies.

description: We explore the Rényi entanglement entropies of a one-dimensional (line) subsystem of length $L$ embedded in two-dimensional $L\times L$ square lattice for quantum spin models whose ground-state breaks a continuous symmetry in the thermodynamic limit. Using quantum Monte Carlo simulations, we first study the $J_1 - J_2$ Heisenberg model with antiferromagnetic nearest-neighbor $J_1>0$ and ferromagnetic second-neighbor couplings $J_2\le 0$. The signature of SU(2) symmetry breaking on finite size systems, ranging from $L=4$ up to $L=40$ clearly appears as a universal additive logarithmic correction to the Rényi entanglement entropies: $l_q \ln L$ with $l_q\simeq 1$, independent of the Rényi index and values of $J_2$. We confirm this result using a high precision spin-wave analysis (with restored spin rotational symmetry) on finite lattices up to $10^5\times 10^5$ sites, allowing to explore further non-universal finite size corrections and study in addition the case of U(1) symmetry breaking. Our results fully agree with the prediction $l_q=n_G/2$ where $n_G$ is the number of Goldstone modes, by Metlitski and Grover [arXiv:1112.5166].

description: Bmper, which is orthologous to Drosophila melanogaster crossveinless 2, is a secreted factor that regulates Bmp activity in a tissue- and stage-dependent manner. Both pro- and anti-Bmp activities have been postulated for Bmper, although the molecular mechanisms through which Bmper affects Bmp signaling are unclear. In this paper, we demonstrate that as molar concentrations of Bmper exceed Bmp4, Bmper dynamically switches from an activator to an inhibitor of Bmp4 signaling. Inhibition of Bmp4 through a novel endocytic trap-and-sink mechanism leads to the efficient degradation of Bmper and Bmp4 by the lysosome. Bmper-mediated internalization of Bmp4 reduces the duration and magnitude of Bmp4-dependent Smad signaling. We also determined that Noggin and Gremlin, but not Chordin, trigger endocytosis of Bmps. This endocytic transport pathway expands the extracellular roles of selective Bmp modulators to include intracellular regulation. This dosage-dependent molecular switch resolves discordances among studies that examine how Bmper regulates Bmp activity and has broad implications for Bmp signal regulation by secreted mediators.

description: We investigated the diet of the yellowtail surgeonfish Prionurus punctatus (Gill, 1862), determined from the stomach contents of 120 individuals, caught monthly from November 2004 to October 2005 on the Los Frailes reef, B.C.S., Mexico. Of all organisms caught, 86 had food in their stomachs, and 34 were empty. In order to characterize the diet by sex, by size and by season, the frequency of occurrence and gravimetric methods were used in the combined index of relative importance (IRI). We determined that the yellowtail surgeonfish P. punctatus is a strict herbivore; overall, we identified 25 food items, of which 15 algae belonged to the Class Rhodophyceae, 7 to the Chlorophyceae, and 3 to the Phaeophyceae. According to the IRI, the most important algae in the diet were: Rhodophyta (20.48%), Gracilaria sp. (15.98%), unidentified organic matter UOM (12.56%), Chlorophyta (9.75%), Hypnea musciformis (9.15%), Jania mexicana (6.17%), Sphacelaria sp. (4.29%) and Dictyota flabellata (4.05%). The diversity of the diet was intermediate (H´ = 2.48); the diet also varied according to size and season. This could be due in part to size segregation in yellowtail surgeonfish; with smaller sizes feeding in shallower areas, and medium and large sizes feeding in deeper areas. The availability of algae on the reef on which P. punctatus feed varies spatially as well as with the season.
Lebenslanges Lernen als Schulalptraum? Ikonographische, ikonologische und ikonische Aspekte einer Debatte

description: Dieser Beitrag widmet sich, vor dem Hintergrund der anhaltenden bildungspolitischen Diskussion um lebenslanges Lernen, der bildhaften Darstellung dieses Diskurses. Es wird die These vertreten, dass in der Ikonographie des lebenslangen Lernens ikonologisch analysierbare Wissens- und Orientierungsgehalte aufgehoben sind, die in den zumeist programmatischen Debatten zum lebenslangen Lernen nicht oder nur wenig Berücksichtigung finden, diesen aber implizit stark beeinflussen. Zu diesen Gehalten gehören zentral überlieferte Alter(n)sbilder, die nach wie vor an eine Dreiteilung des Lebenslaufs in Vorerwerbs, Erwerbs- und Nacherwerbsphase anschließen, wobei gerade im mittleren Lebensalter kein Platz für Weiterbildungsaktivitäten vorgesehen ist. Anhand der Analyse einer als Karikatur angelegten Illustration innerhalb eines Artikels zum lebenslangen Lernen wird diese These exemplarisch herausgearbeitet. Einer einleitenden Differenzierung zwischen bildhaften und schriftlichen Diskursen zum lebenslangen Lernen (1) folgt eine kurze quantitative Charakterisierung der Bebilderung des Weiterbildungsdiskurses im Internet (2), die als Vorbereitung für eine exemplarische dokumentarische Bildanalyse einer Weiterbildungskarikatur dient (3).Im Anschluss daran wird die These von der Korrespondenz von Bildern lebenslangen Lernens mit Alter(n)sbildern etwas abstrakter weiterentwickelt (4) und einige Hinweise auf ein daran anschließendes laufendes Forschungsprojekt zu Weiterbildungsbeteiligung und Altersbilder der Babyboomer (WAB) gegeben (5). In diesem stellt die im Beitrag dargestellte Abbildanalyse einen Teil eines umfassenderen Forschungsdesigns dar, das bildanalytische Verfahren mit anderen qualitativen Verfahren trianguliert.

This study was based mainly on frequency of occurrence (F%), numeric percentage (Cn%), percentage by weight (Cw%), and the evolution of the index of relative importance (IRI) with respect to fish size, season and sex. Of the total number of stomachs examined, 1150 were empty (%VI = 81.85). This percentage varied significant- ly with season and among fish size. This sparid principally fed on Molluscs (%IRI = 37.2) and Teleosts (%IRI = 29.77), while plants (%IRI = 15.96) and crustaceans (%IRI = 14.47) were the also important food categories consumed. There were no significant differences neither in the diet between males and females nor among size-classes but significant differences were found with season.

description: Inducing magnetism onto a topological crystalline insulator (TCI) has been predicted to result in several novel quantum electromagnetic effects. This is a consequence of the highly strain-sensitive band topology of such symmetry-protected systems. We thus show that placing the TCI surface of SnTe in proximity to EuS, a ferromagnetic insulator, induces magnetism at the interface between SnTe and EuS and thus breaks time-reversal-symmetry in the TCI. Magnetotransport experiments on SnTe-EuS-SnTe trilayer devices reveal a hysteretic lowering of the resistance at the TCI surface that coincides with an increase in the density of magnetic domain walls. This additional conduction could be a signature of topologically-protected surface states within domain walls. Additionally, a hysteretic anomalous Hall effect reveals that the usual in-plane magnetic moment of the EuS layer is canted towards a perpendicular direction at the interface. These results are evidence of induced magnetism at the SnTe-EuS interfaces resulting in broken time-reversal symmetry in the TCI.

description: Resource sharing models directly address the allocation of a remaining global budget among countries. This paper shines the spotlight on the mathematical formulae of resource sharing models. Models for determining national emission pathways are described in detail. These models are based on the allocation of a global emission pathway (e. g. convergence models) and the direct allocation of a global budget (models within the Extended Smooth Pathway Model). Thus, this paper contributes to greater transparency and comparability through a uniform mathematical representation, by showing generalisations as well as relations, similarities, and differences between the models. It also contains mathematical proofs for specified properties of the models.

description: Histone H2B monoubiquitination by Rad6/Bre1 is required for the trimethylation of both histone H3K4 and H3K79 by COMPASS and Dot1 methyltransferases, respectively. The dependency of methylation at H3K4 and H3K79 on the monoubiquitination of H2BK123 was recently challenged, and extragenic mutations in the strain background used for previous studies or epitope-tagged proteins were suggested to be the sources of this discrepancy. In this study, we show that H3K4 and H3K79 methylation is solely dependent on H2B monoubiquitination regardless of any additional alteration to the H2B sequence or genome. Furthermore, we report that Y131, one of the yeast histone H2A/H2B shuffle strains widely used for the last decade in the field of chromatin and transcription biology, carries a wild-type copy of each of the HTA2 and HTB2 genes under the GAL1/10 promoter on chromosome II. Therefore, we generated the entire histone H2A and H2B alanine-scanning mutant strains in another background, which does not express wild-type histones.

description: In early 2014 an outbreak of a slightly mutated Zaire Ebola subtype appeared in West Africa which is less virulent than 1976 and 1994 strains. The numbers of cases per year appear to be ~ 1000 times larger than the earlier strains, suggesting a greatly enhanced transmissibility. Although the fraction of the 2014 spike glycoprotein mutations is very small (~3%), the mortality is significantly reduced, while the transmission appears to have increased strongly. Bioinformatic scaling had previously shown similar inversely correlated trends in virulence and transmission in N1 (H1N1) and N2 (H3N2) influenza spike glycoprotein mutations. These trends appear to be related to various external factors (migration, availability of pure water, and vaccination programs). The molecular mechanisms for Ebola's mutational response involve mainly changes in the disordered mucin-like domain (MLD) of its spike glycoprotein amino acids. The MLD has been observed to form the tip of an oligomeric amphiphilic wedge that selectively pries apart cell-cell interfaces via an oxidative mechanism.

description: Chibby (Cby) is a conserved component of the Wnt–β-catenin pathway. Cby physically interacts with β-catenin to repress its activation of transcription. To elucidate the function of Cby in vertebrates, we generated Cby−/− mice and found that after 2–3 d of weight loss, the majority of mice die before or around weaning. All Cby−/− mice develop rhinitis and sinusitis. When challenged with Pseudomonas aeruginosa isolates, Cby−/− mice are unable to clear the bacteria from the nasal cavity. Notably, Cby−/− mice exhibit a complete absence of mucociliary transport caused by a marked paucity of motile cilia in the nasal epithelium. Moreover, ultrastructural experiments reveal impaired basal body docking to the apical surface of multiciliated cells. In support of these phenotypes, endogenous Cby protein is localized at the base of cilia. As the phenotypes of Cby−/− mice bear striking similarities to primary ciliary dyskinesia, Cby−/− mice may prove to be a useful model for this condition.
Intrakinetochore stretch is associated with changes in kinetochore phosphorylation and spindle assembly checkpoint activity

description: Cells have evolved a signaling pathway called the spindle assembly checkpoint (SAC) to increase the fidelity of chromosome segregation by generating a “wait anaphase” signal until all chromosomes are properly aligned within the mitotic spindle. It has been proposed that tension generated by the stretch of the centromeric chromatin of bioriented chromosomes stabilizes kinetochore microtubule attachments and turns off SAC activity. Although biorientation clearly causes stretching of the centromeric chromatin, it is unclear whether the kinetochore is also stretched. To test whether intrakinetochore stretch occurs and is involved in SAC regulation, we developed a Drosophila melanogaster S2 cell line expressing centromere identifier–mCherry and Ndc80–green fluorescent protein to mark the inner and outer kinetochore domains, respectively. We observed stretching within kinetochores of bioriented chromosomes by monitoring both inter- and intrakinetochore distances in live cell assays. This intrakinetochore stretch is largely independent of a 30-fold variation in centromere stretch. Furthermore, loss of intrakinetochore stretch is associated with enhancement of 3F3/2 phosphorylation and SAC activation.

description: We develop a frame and dyad gauge-independent formalism for the calculus of variations of functionals involving spinorial objects. As part of this formalism we define a modified variation operator which absorbs frame and spin dyad gauge terms. This formalism is applicable to both the standard spacetime (i.e. SL(2,C)) 2-spinors as well as to space (i.e. SU(2,C)) 2-spinors. We compute expressions for the variations of the connection and the curvature spinors.

description: Obwohl angesichts aktueller Entwicklungen die Bedeutung der Friedenspädagogik außer Frage steht, ist ihre theoretische Grundlegung noch weitgehend in Diskussion. Da diese Problematik eng mit dem Konstitutivelement „Frieden“ verbunden ist, werden zunächst in einem Umblick Strukturen der Thematisierung von Frieden aus historischer Sicht vorgestellt und anschließend in einem Einblick Aspekte der Systematisierung von Frieden analysiert. In Form eines Ausblicks werden schließlich Möglichkeiten aufgezeigt, Friedenspädagogik theoretisch zu begründen und methodisch zu reflektieren.

description: The LMNA gene encodes lamins A and C, two intermediate filament-type proteins that are important determinants of interphase nuclear architecture. Mutations in LMNA lead to a wide spectrum of human diseases including autosomal dominant Emery-Dreifuss muscular dystrophy (AD-EDMD), which affects skeletal and cardiac muscle. The cellular mechanisms by which mutations in LMNA cause disease have been elusive. Here, we demonstrate that defects in neuromuscular junctions (NMJs) are part of the disease mechanism in AD-EDMD. Two AD-EDMD mouse models show innervation defects including misexpression of electrical activity–dependent genes and altered epigenetic chromatin modifications. Synaptic nuclei are not properly recruited to the NMJ because of mislocalization of nuclear envelope components. AD-EDMD patients with LMNA mutations show the same cellular defects as the AD-EDMD mouse models. These results suggest that lamin A/C–mediated NMJ defects contribute to the AD-EDMD disease phenotype and provide insights into the cellular and molecular mechanisms for the muscle-specific phenotype of AD-EDMD.

description: Despite having the simplest atomic structure, bulk FeSe has an observed electronic structure with the largest deviation from the band theory predictions among all Fe-based superconductors and exhibits a low temperature nematic electronic state without intervening magnetic order. We show that the Fe-Fe interatomic Coulomb repulsion $V$ offers a natural explanation for the puzzling electron correlation effects in FeSe superconductors. It produces a strongly renormalized low-energy band structure where the van Hove singularity sits remarkably close to Fermi level in the high-temperature electron liquid phase as observed experimentally. This proximity enables the quantum fluctuations in $V$ to induce a rotational symmetry breaking electronic bond order in the $d$-wave channel. We argue that this emergent low-temperature $d$-wave bond nematic state, different from the commonly discussed ferro-orbital order and spin-nematicity, has been observed recently by several angle resolved photoemission experiments detecting the lifting of the band degeneracies at high symmetry points in the Brillouin zone. We present a symmetry analysis of the space group and identify the hidden antiunitary $T$-symmetry that protects the band degeneracy and the electronic order/interaction that can break the symmetry and lift the degeneracy. We show that the $d$-wave nematic bond order, together with the spin-orbit coupling, provide a unique explanation of the temperature dependence, momentum space anisotropy, and domain effects observed experimentally. We discuss the implications of our findings on the structural transition, the absence of magnetic order, and the intricate competition between nematicity and superconductivity in FeSe superconductors.

description: Various applications in signal processing and machine learning give rise to highly structured spectral optimization problems characterized by low-rank solutions. Two important examples that motivate this work are optimization problems from phase retrieval and from blind deconvolution, which are designed to yield rank-1 solutions. An algorithm is described that is based on solving a certain constrained eigenvalue optimization problem that corresponds to the gauge dual which, unlike the more typical Lagrange dual, has an especially simple constraint. The dominant cost at each iteration is the computation of rightmost eigenpairs of a Hermitian operator. A range of numerical examples illustrate the scalability of the approach.
