description: In the soil surrounding the plant root, or rhizosphere, many beneficial microbes reside and are classified as plant growth promoting bacteria (PGPB) (Mendes et al., 2013). Erodium cicutarium is invasive and tends to thrive after ecological disturbances, though the microbial impact on the plant’s survival is unknown (Howard, 1992). In December 2017, the Skirball Fire ravaged Los Angeles. At one site affected by the fire, a soil sample was collected from E. cicutarium, or the common stork’s-bill. This study aimed to show that microorganisms in the rhizosphere of the stork’s-bill had plant growth properties one-year postfire and that the composition of these bacteria had been altered in such a way that allowed the plant to survive in non-native environments. Biochemical and functional assays demonstrated that microorganisms from the soil sample had plant growth promoting properties. Out of 10 eighteen isolates tested, 22% could fix nitrogen, 44% could solubilize phosphate, and 39% could produce siderophores. From environmental DNA sequencing of the 16S rDNA, there were not many differences between native and invasive samples that were biologically and statistically significant (p>0.05). However, there were statistically more nitrogen fixing Burkholderia in native soil samples compared to invasive samples (p=0.006). Since microorganisms from the soil near the invasive stork’s bill one-year post fire had plant growth promoting properties, they may have played a role in enhancing plant growth and aiding in recovery after environmental stressors (Bockman, 1985).

description: Before we dive into the accessibility stream of nowadays indicatory applications of octonions to computer and other sciences and to quantum physics let us focus for a while on the crucially relevant events for todays revival on interest to nonassociativity. Our reflections keep wandering back to the $Brahmagupta$ $Fibonacc$ two square identity and then via the $Euler$ four square identity up to the $Degen$ $Ggraves$ $Cayley$ eight square identity. These glimpses of history incline and invite us to retell the story on how about one month after quaternions have been carved on the $Broughamian$ bridge octonions were discovered by $John$ $Thomas$ $Ggraves$, jurist and mathematician, a friend of $William$ $Rowan$ $Hamilton$. As for today we just mention en passant quaternionic and octonionic quantum mechanics, generalization of $Cauchy$ $Riemann$ equations for octonions and triality principle and $G_2$ group in spinor language in a descriptive way in order not to daunt non specialists. Relation to finite geometries is recalled and the links to the 7stones of seven sphere, seven imaginary octonions units in out of the $Plato$ cave reality applications are appointed . This way we are welcomed back to primary ideas of $Heisenberg$, $Wheeler$ and other distinguished fathers of quantum mechanics and quantum gravity foundations.

description: We investigated the magnetotransport properties of high-mobility InAs/GaSb antidot lattices. For samples with large antidot diameter, we found a broad maximum of classical origin around 2.5 T in addition to the usual commensurability features at low magnetic fields. The broad maximum can be ascribed to a class of orbits involving multiple reflections on a single antidot. This is shown by both a simple transport calculation based on a classical Kubo formula and an analysis of the Poincaré sections at different magnetic-field values. At low temperatures we observe weak 1/B- periodic oscillations superimposed on the classical maximum.

description: One of the biggest concerns with phage therapy is the potential inflammatory response produced by lytic phages when lysing antibiotic resistant bacteria. To address this, temperate phages could be used as genetic vectors to deliver genes that turn off bacterial pathogenicity islands, which contain virulence factors. Although there have been studies about using temperate phages as vectors, not many specifically addressed their use in phage therapy. Since a temperate bacteriophage in its lysogenic phase may undergo horizontal gene transfer with its host’s genome, if optimal temperature and pH conditions for lysogenic growth are established for a temperate phage and its genome is analyzed, then environmental and genetic influences on temperate phages’ life cycle decisions can be determined and utilized to improve the use of temperate phages as genetic vectors. The individual and simultaneous effects of changing temperature and pH were tested on the growth of phage OmegaMRC (grown on Mycobacterium smegmatis). Plaque morphologies were used to assess the life cycle choice of the phage. There was a trend towards lysogeny at higher temperatures and pH (p< 0.05). The genome of a separate temperate phage, SgtBeansprout, was analyzed, and genes indicating lysogeny and potential traces of horizontal gene transfer were annotated. Overall, discovery of optimal lysogenic conditions for phage OmegaMRC and genomic analysis of a similar temperate phage, SgtBeansprout, showed life cycle-specific genes that may be controlled by external conditions or may enable genetic recombination with other microbes’ genomes. This knowledge could contribute to the future use of temperate phages for therapeutic purposes.

description: We discuss several aspects of astroparticle physics pertaining to a new model with MeV cold dark matter particles, which annihilate to electron-positron pairs in a manner yielding the correct CDM density required today, and explaining the enhanced electron-positron annihilation line from the center of the Galaxy. We note that the mass of the vector meson mediating the annihilations, should exceed the mass of CDM particle, and comment on possible enhancement due to CDM clustering, on the detectability of the new CDM, and on particle physics models incorporating this scenario.

description: Plants and soil bacteria have dynamic relationships, and may interact symbiotically to aid their growth and survival (Tas et al., 2013). Disruptions to the soil such as wildfires have been shown to change the soil microbial composition by increasing plant growth-promoting bacteria and nitrogen-fixing bacteria (DeBano 1990). This study explores the effect of the 2017 Skirball Fire on the Getty View Park soil microbiome to examine whether shifts in the endogenous soil composition favor plant growth-promoting factors to help restore pre-fire conditions. If novel plant growth-promoting bacteria from the soil are identified, the agricultural dependency on chemical fertilizers can be reduced. Testing cultivated isolates identified the presence of nitrogen fixing (50%) and phosphate solubilizing bacteria (97%) 6 with some having overlapping functions. Species testing positive for one or more factors were subject to genomic collection and amplification in order to examine the 16S rRNA gene to assign hypothesized identity. To examine the microbial community and view functional shifts, the metagenome of the soil was sequenced. Comparisons between one month and one year post-fire showed that the abundance of the nifA gene used in nitrogen fixation decreased (p=.049) as time passed. Plant growth-promoting bacteria, Proteobacteria and Actinobacteria were not significantly increased (p>0.05), contrasting appA, a gene important in phosphorus solubilization, increasing (p=4.70e-6). Thus, when given time to recuperate after wildfires, the microbial community changes to meet the changing environment. If the factors that caused these shifts are identified, microbial communities in other environments can be altered to aid restoration after drastic environmental changes.

description: The properties of Mn-doped GaAs are studied at several doping levels and hole compensations, using a real-space Hamiltonian on an fcc lattice that reproduces the valence bands of undoped GaAs. Large-scale Monte Carlo (MC) simulations on a Cray XT3 supercomputer, using up to a thousand nodes, were needed to make this effort possible. Our analysis considers both the spin-orbit interaction and the random distribution of the Mn ions. The hopping amplitudes are functions of the GaAs Luttinger parameters. At the coupling J~1.2eV deduced from photoemission experiments, the MC Curie temperature and the shape of the magnetization curves are in agreement with experimental results for annealed samples. Although there are sizable differences with mean-field predictions, the system is found to be closer to a hole-fluid regime than to localized carriers.

description: Introduction: Mental health policies have encouraged removals of psychiatric beds in many countries. It is under debate whether to continue those trends. We conducted a systematic review of expert arguments for trends of psychiatric bed numbers. Methods: We searched seven electronic databases and screened 15,479 papers to identify expert opinions, arguments and recommendations for trends of psychiatric bed numbers, published until December 2020. Data were synthesized using thematic analysis and classified into arguments to maintain or increase numbers and to reduce numbers. Results: One hundred six publications from 25 countries were included. The most common themes arguing for reductions of psychiatric bed numbers were inadequate use of inpatient care, better integration of care and better use of community care. Arguments to maintain or increase bed numbers included high demand of psychiatric beds, high occupancy rates, increasing admission rates, criminalization of mentally ill, lack of community care and inadequately short length of stay. Cost effectiveness and quality of care were used as arguments for increase or decrease. Conclusions: The expert arguments presented here may guide and focus future debate on the required psychiatric bed numbers. The recommendations may help policymakers to define targets for psychiatric bed numbers. Arguments need careful local evaluation, especially when supporting opposite directions of trends in different contexts.

description: Background and Objectives: Despite the long-standing consensus on the importance of tumor size, tumor number and carcinoembryonic antigen (CEA) levels as predictors of long-term outcomes among patients with colorectal liver metastases (CRLM), optimal prognostic cut-offs for these variables have not been established. Methods: Patients who underwent curative-intent resection of CRLM and had available data on at least one of the three variables of interest above were selected from a multi-institutional dataset of patients with known KRAS mutational status. The resulting cohort was randomly split into training and testing datasets and recursive partitioning analysis was employed to determine optimal cut-offs. The concordance probability estimates (CPEs) for these optimal cut offs were calculated and compared to CPEs for the most widely used cut-offs in the surgical literature. Results: A total of 1643 patients who met eligibility criteria were identified. Following recursive partitioning analysis in the training dataset, the following cut-offs were identified: 2.95 cm for tumor size, 1.5 for tumor number and 6.15 ng/ml for CEA levels. In the entire dataset, the calculated CPEs for the new tumor size (0.52), tumor number (0.56) and CEA (0.53) cut offs exceeded CPEs for other commonly employed cut-offs. Conclusion: The current study was able to identify optimal cut-offs for the three most commonly employed prognostic factors in CRLM. While the per variable gains in discriminatory power are modest, these novel cut-offs may help produce appreciable increases in prognostic performance when combined in the context of future risk scores.

description: The results of Brownian dynamics simulations of a single DNA molecule in shear flow are presented taking into account the effect of internal viscosity. The dissipative mechanism of internal viscosity is proved necessary in the research of DNA dynamics. A stochastic model is derived on the basis of the balance equation for forces acting on the chain. The Euler method is applied to the solution of the model. The extensions of DNA molecules for different Weissenberg numbers are analyzed. Comparison with the experimental results available in the literature is carried out to estimate the contribution of the effect of internal viscosity.

description: SYNTAX score is one of the risk assessment systems to predict cardiac events in acute coronary syndrome patients. Despite the large number of SYNTAX score benefits, invasive methods such as coronary angiography are necessary to perform the scoring. We hypothesized that ECG parameters could predict the SYNTAX score in unstable angina patients. During the retrospective cohort study, a total number of 876 patients were diagnosed with unstable angina. After applying the exclusion criteria, 600 patients were divided into tertiles based on the SYNTAX scores as low (0–22), intermediate (23–32), and high (≥ 33). The association between ECG parameters and SYNTAX score was investigated. The study included 65% men and 35% women with a mean age of 62.4 ± 9.97 years.

A search for faint variable stars in the globular cluster M71

description: A 67" x 104" area of the metal-rich globular cluster M71 was searched for variable stars using 73 CCD frames. Using mean B and V values a colour-magnitude diagram down to V ≈ 22 is constructed. Four variables were discovered, with two more stars classed as possible candidates for variability. Phase diagrams and real time light curves are presented for all variables. One variable blue straggler (or SX Phe star) has been discovered with a period of 0.d05181. Values for the mass depend on the pulsation mode assumed for this star - (0.90 ± 0.13)M. for the first overtone mode, and (1.57 ± 0.22)M. for the fundamental mode. A second variable, of similar period (0.d06053), but with a magnitude l.m75 below the main sequence turn off was also found but it may be a field star. Two candidate eclipsing binary systems were found. The most likely period of one is 0.d37244. This value, and the shape of the light curve, suggest it may be a W UMa type variable. Its position on the CMD suggests that it too may be a field star. No period was obtainable for the other candidate binary due to a lack of phase coverage. Further data is needed to confirm and strengthen these claims.

Nosomma monstrosum

description: Nosomma monstrosum (Nuttall and Warburton, 1908)
 Nosomma monstrosum is an unusual species which was originally classified, with reservations, as a Hyalomma, although it also shows certain characteristics of the genus Dermacentor (Nuttall and Warburton 1908; Warburton 1918). It does not possess the elongate mouthparts and beady eyes of Hyalomma but does possess enamelling and male ventral shields (Schulze 1920). Adult N. monstrosum are most commonly found on buffalo, although they have also been recorded from cattle, horses, pigs and dogs (Hoogstraal 1985b; Petney and Keirans 1996b). Immatures occur mainly on rodents. This species is found in Lao PDR, Myanmar, Thailand, and Vietnam (Toumanoff 1944; Tanskul et al. 1983; Hoogstraal 1985b; Kolonin 1992, 2009), as well as India, Nepal, Sri Lanka and Bangladesh (Kolonin 2009). The life cycle has been determined for a Sri Lankan population of this species (Bandaranayaka et al. 2016).
Descriptions of adults are found in Arthur and Chaudhuri (1965) and immatures in Singh (1968).

description: This study explores the impact of targeted activities on improving the peace quotient of teacher trainees. Using an experimental single-group pre-test and post-test design, the study identified 31 out of 107 B.Ed. students with low peace quotient scores, characterized by belligerent, pugnacious, or passive-aggressive tendencies. Intervention activities aimed at fostering emotional harmony were implemented and evaluated using the Peace Quotient Quiz by Cait Johnson. The results revealed a significant increase in peace-promoting behaviours post-intervention, highlighting the effectiveness of the planned activities in addressing emotional and behavioural challenges. The findings emphasize the importance of integrating peace-building and emotional intelligence programs into teacher education curricula to cultivate harmonious educators and create positive classroom environments. Recommendations for scalability and future research are provided to enhance the study’s impact.

description: One approach to future high energy particle accelerators is based on the wakefield principle: a leading high-charge drive bunch is used to excite fields in an accelerating structure or plasma that in turn accelerates a trailing low-charge witness bunch. The transformer ratio R is defined as the ratio of the maximum energy gain of the witness bunch to the maximum energy loss of the drive bunch. In general, for configurations in which the two beams traverse the accelerator along the same trajectory (collinear wakefield acceleration). A number of techniques have been proposed to overcome the transformer ratio limitation. We report here the first experimental study of the ramped bunch train (RBT) technique in which a dielectric loaded waveguide was used as the accelerating structure. A single drive bunch was replaced by two bunches with charge ratio of 1:2.5 and a separation of 10.5 wavelengths of the fundamental mode. An average measured transformer ratio enhancement by a factor of 1.31 over the single drive bunch case was obtained in this experiment.

LTB universes as alternatives to dark energy: does positive averaged acceleration imply positive cosmic acceleration?

description: We show that positive averaged acceleration obtained in LTB models through spatial averaging can require integration over a region beyond the event horizon of the central observer. We provide an example of a LTB model with positive averaged acceleration in which the luminosity distance does not contain information about the entire spatially averaged region, making the averaged acceleration unobservable. Since the cosmic acceleration is obtained from fitting the observed luminosity distance to a FRW model we conclude that in general a positive averaged acceleration in LTB models does not imply a positive FRW cosmic acceleration.

description: Using homogeneous CCD photometric data from the 105-cm Kiso Schmidt telescope covering a 50' x 50' field, we study the mass functions (MFs) of nine open clusters. The ages and Galactocentric distances of the target clusters vary from 16 - 2000 Myr and 9-10.8 kpc, respectively. The values of MF slopes vary from -1.1 to -2.1. The classical value derived by Salpeter (1955) for the slope of the IMF is Γ= -1.35. The MFs in the outer regions of the clusters are found to be steeper than in the inner regions, indicating the presence of mass segregation in the clusters.The MF slopes (in the outer region as well as the whole cluster) undergo an exponential decay with the evolutionary parameter τ(= age/ relaxation time). It seems that the evaporation of low-mass members from outer regions of the clusters is not significant at larger Galactocentric distances. It is concluded that the initial mass function (IMF) in the anticentre direction of the Galaxy might have been steeper than the IMF in the opposite direction. A comparison of the observed CMDs of the clusters with synthetic CMDs gives a photometric binary content of ~40%.

description: We investigate the evolution over the last 6.3 Gyr of cosmic time (i.e., since z ~ 0.7) of the average X-ray properties of early-type galaxies within the Extended Chandra Deep Field-South (E-CDF-S). Our early-type galaxy sample includes 539 objects with red-sequence colors and Sersic indices larger than n = 2.5, which were selected jointly from the COMBO-17 (Classifying Objects by Medium-Band Observations in 17 Filters) and GEMS (Galaxy Evolution from Morphologies and SEDs) surveys. We utilize the deep Chandra observations over the E-CDF-S and X-ray stacking analyses to constrain primarily the average X-ray emission from "normal" early-type galaxies (i.e., those that are not dominated by luminous active galactic nuclei [AGNs]). In our analyses, we study separately optically luminous (L_B ~ 10^[10-11] L_B,sol) and faint (L_B ~ 10^[9.3-10] L_B,sol) galaxy samples, which we expect to have soft (0.5-2.0 keV) X-ray emission dominated by hot (~1 keV) interstellar gas and low mass X-ray binary (LMXB) populations, respectively. We detect individually 49 (~9%) of our galaxies in the X-ray band, and classify these sources as either normal early-type galaxies (17 galaxies) or AGN candidates (32 galaxies). The AGN fraction of our optically luminous samples evolves with redshift in a manner consistent with the (1+z)^3 evolution observed in other investigations of X-ray-selected AGNs. After removing potential AGNs from our samples, we find that the X-ray-to-B-band mean luminosity ratio (L_X/L_B) for optically luminous early-type galaxies does not evolve significantly over the redshift range z~0.0-0.7. This lack of X-ray evolution implies a general balance between the heating and cooling of the hot interstellar gas [Abridged].

description: Portale delle antiche scritture del Mediterraneo (dalle origini al VI secolo d.C.)
Mnamon intende fornire informazioni su quanto di utile e di meglio si trova sul web per lo studio e la ricerca nell'ambito delle scritture antiche del Mediterraneo: archivi di documenti, centri di ricerca, strumenti bibliografici, materiali didattici.
Le informazioni sono selezionate e recensite criticamente da specialisti. Di ogni scrittura è fornita una breve presentazione che indica luoghi e tempi di attestazione, caratteristiche della scrittura e lingue che la utilizzano.
La redazione procede attraverso il lavoro individuale o di piccoli gruppi di specialisti di ogni singola scrittura ed è integrato parallelamente da una regolare attività seminariale collettiva che coinvolge tutti i collaboratori.
Il Portale è perciò rivolto a un’utenza che va dagli studenti ai ricercatori specialisti.

Geometric torsions and invariants of manifolds with triangulated boundary

Publisher: name: arXiv

Subjects: subject: Geometric Topology (math.GT)
subject: Algebraic Topology (math.AT)

subject: FOS: Mathematics

description: Geometric torsions are torsions of acyclic complexes of vector spaces which consist of differentials of geometric quantities assigned to the elements of a manifold triangulation. We use geometric torsions to construct invariants for a manifold with a triangulated boundary. These invariants can be naturally united in a vector, and a change of the boundary triangulation corresponds to a linear transformation of this vector. Moreover, when two manifolds are glued by their common boundary, these vectors undergo scalar multiplication, i.e., they work according to M. Atiyah's axioms for a topological quantum field theory.

Strangeness-Conserving Hadronic Parity Violation at Low Energies
Creators: name: Liu, C. -P.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The parity-violating nucleon-nucleon interaction is the key to understanding the strangeness-conserving hadronic weak interaction at low energies. In this brief talk, I review the past accomplishments in and current status of this subject, and outline a new joint effort between experiment and theory that tries to address the potential problems in the past by focusing on parity violation in few-nucleon systems and using the language of effective field theory.

subject: 60F10

description: In this paper we consider the Anderson Hamiltonian with white noise potential on the box $[0,L]^2$ with Dirichlet  boundary conditions.  We show that all the eigenvalues divided by $log L$ converge as $Lrightarrow infty$ almost surely to the same  deterministic constant, which is given by a variational formula.
Crystalline electric fields and the ground state of Ce$_{3}$Rh$_{4}$Pb$_{13}$

description: We have succeeded in synthesizing of single crystals of a new intermetallic compound, Ce$_{3}$Rh$_{4}$Pb$_{13}$. Magnetic susceptibility measurements indicate that the Ce moments are highly localized, despite the metallic character of the electrical resistivity. Heat capacity measurements reveal that the cubic crystal electric field lifts the six-fold degeneracy of the Ce$^{3+}$ ground state, with the quartet state separated by approximately 60 K from the doublet ground state. The magnetic field dependence of the heat capacity at low temperature indicates a further splitting of the doublet, but no sign of magnetic order was found above 0.35 K.

Neuroinflammation: 2022 update
Creators: name: Lassmann, Hans
Publisher: name: Free Neuropathology
Year: 2022

description: Besides important progress in the understanding of the pathological substrate of COVID-19-associated brain disease, major insights into mechanisms of neurodegeneration in human disease have been provided in neuropathological studies published in 2021. Recently developed techniques, which allow the simultaneous detection of a large battery of different molecules within single cells, have proven useful in the analysis of disease mechanisms in experimental and human neuroinflammatory conditions. They have elucidated protective and detrimental effects of activated microglia, which act in a stage and context-dependent manner in the induction and propagation of neurodegeneration. In addition, they emphasize the importance of synaptic damage and of selective neuronal vulnerability in the respective diseases. The results provide important new insights with high clinical relevance.

инвариант Лапласа

description: Исследована динамика перемещений частиц в рамках релятивистской модели, представляющей собой евклидово пространство с тремя вещественными пространственными осями и одной, соответствующей местному (собственному) времени. Выдвинуто предположение об изотропности данного тетрамерного пространства при малых скоростях объектов как следствие положения о равноценности пространственных и собственных временных координат. В результате расчетов найдены уравнения траекторий, которые классифицированы как движение по инерции. В трехмерном пространственном базисе, помимо тривиальных решений, в их число входят ускоренные движения под действием сил гармонического и гравитационного поля. В последнем случае реализация движений возможна при допущении двухмерности или комплексности собственного времени частиц. Инвариант Лапласа образован вещественными компонентами координат и скоростей.

D2.1: Requirements of the Facility
Creators: name: 5Genesis
Publisher: name: Zenodo
Year: 2021

description: The main purpose of this deliverable is to summarise the outcome of the first technical task of 5GENESIS, Task 2.1, targeting at the definition of the requirements of the envisaged 5G Facility. However, being the first technical deliverable of the 5GENESIS project, the document also presents a distilled view of the project’s scope and objectives, and highlights the innovations and ambitions that are set to be fulfilled. It delves into the technological solutions that are part of 5GENESIS, aiming at clarifying how the project will build on the existing technologies and go beyond them. In this context, the deliverable is expected to serve as a fundamental reference guide for specifying the 5GENESIS Facility and determining the subsequent implementation work.

Rhipicephalus annulatus

description: Rhipicephalus annulatus (Say, 1821)
 This species is included as a parasite of cattle from northern Vietnam in Chien et al. (2016); however, it does not occur in surrounding countries (Chen et al. 2010; Lao PDR-Vongphayloth et al. 2016). The nearest populations are possibly those in southern India although these require confirmation (Ghosh et al. 2007). This should be investigated in more detail, as R. microplus found in Southeast Asia (Petney and Keirans 1996a) may represent a species group with new species awaiting identification (Burger et al. 2014). Alternatively, R. annulatus may have been introduced on cattle sometime in the past.
