Observation of electromagnetic Dalitz decays J/psi -> Pe(+)e(-)

Based on a sample of (225.3 +/- 2.8) x 10(6) J/psi events collected with the BESIII detector, the electromagnetic Dalitz decays of J/psi -> Pe(+)e(-)(P = eta'/eta/pi(0)) are studied. By reconstructing the pseudoscalar mesons in various decay modes, the decays J/psi -> eta'e(+)e(-), J/psi -> eta e(+)e(-), and J/psi -> pi(0)e(+)e(-) are observed for the first time. The branching fractions are determined to be B(J/psi -> eta'e(+)e(-)) = (5.81 +/- 0.16 +/- 0.31) x 10(-5), B(J/psi -> eta e(+)e(-)) = (1.16 +/- 0.07 +/- 0.06) x 10(-5), and B(J/psi -> pi(0)e(+)e(-)) = (7.56 +/- 1.32 +/- 0.50) x 10(-7), where the first errors are statistical and the second ones systematic.
Hydra: An Optimized Data System for Large Multi-Model Deep Learning [Information System Architectures]

In many deep learning (DL) applications, the desire for ever higher accuracy and the new ubiquity of transfer learning has led to a marked increase in the size and depth of model architectures. Thus, the memory capacity of GPUs is often a bottleneck for DL practitioners. Existing techniques that rely on partitioning the model architecture across a network of GPUs suffer from substantial un-derutilization and busy waiting due to sequential dependencies in most large-scale model architectures (Transformers, CNNs). We observe that almost all such prior large-model systems focus on training only one model at a time, but in reality DL practitioners often train many models in bulk due to model selection needs, e.g., hyper-parameter tuning, architecture finetuning, etc. This gap leads to significant system inefficiency. We approach this problem from first principles and propose a new information system architecture for scalable multi-model training that adapts and blends ideas from classical RDBMS design with task parallelism from the ML world. We propose a suite of techniques to optimize system efficiency holistically, including a highly general parameter-spilling design that enables large models to be trained even with a single GPU, a novel multi-query optimization scheme that blends model execution schedules efficiently and maximizes GPU utilization, and a double buffering idea to hide latency. We prototype our ideas on top of PyTorch to build a system we call Hydra. Experiments with real benchmark large-scale multi-model DL workloads show that Hydra is over 7x faster than regular model parallelism and 1.8-4.5X faster than state-of-the-art industrial tools for large-scale model training.
Language-Family Adapters for Multilingual Neural Machine Translation

Massively multilingual models, pretrained on 001 monolingual data, yield state-of-the-art results 002 in a wide range of natural language process-003 ing tasks. In machine translation, multilingual 004 pretrained models are often fine-tuned on par-005 allel data from one or multiple language pairs. 006 Multilingual fine-tuning improves performance 007 on medium-and low-resource languages but 008 requires modifying the entire model and can 009 be prohibitively expensive. Training a new set 010 of adapters on each language pair or training 011 a single set of adapters on all language pairs 012 ( language-pair or language-agnostic adapters) 013 while keeping the pretrained model’s parame-014 ters frozen has been proposed as a parameter-015 efficient alternative. However, the former do 016 not learn cross-lingual representations, while 017 the latter share parameters for all languages 018 and potentially have to deal with negative in-019 terference. In this paper, we propose train-020 ing language-family adapters on top of a pre-021 trained multilingual model to facilitate cross-022 lingual transfer. Our model consistently out-023 performs other adapter-based approaches. We 024 also demonstrate that language-family adapters 025 provide an effective method to translate to lan-026 guages unseen during pretraining. 1 027
von Neumann algebra preduals satisfy the linear biholomorphic property

We prove that for every JBW$^*$-triple $E$ of rank $>1$, the symmetric part of its predual reduces to zero. Consequently, the predual of every infinite dimensional von Neumann algebra $A$ satisfies the linear biholomorphic property, that is, the symmetric part of $A_*$ is zero. This solves a problem posed by M. Neal and B. Russo in [Mathematica Scandinavica, to appear]

MARKETING INNOVATION STRATEGY AND MARKETING PERFORMANCE: A CONCEPTUAL FRAMEWORK

In the globalization era, business firms face rapid changes in both the needs of customers and the nature of markets. Firms, in order to gain competitive advantage and improve performance, need to develop new strategies and practices to attract more customers. This paper offers marketing innovation strategy as one effective method to deal with environment dynamism. Marketing innovation strategy, in this research, refers to new methods in executing variety of marketing strategies to improve marketing outcomes and to increase marketing performance. In corresponding with marketing mix, five dimensions of marketing innovation strategy are presented, namely internet marketing focus (Place/Promotion), relationship marketing concentration (Promotion), customer co-creation orientation (Product/Price), alternative marketing awareness (Product/Price), and alliance marketing concern (Place/ Promotion). As marketing innovation strategy is related to innovation capability and considered a dynamic capability, dynamic capabilities theory is employed to explain the relationships between marketing innovation strategy and its consequence variables, namely brand trust, customer fulfillment, marketing image, and marketing performance. This paper concludes that marketing innovation strategy is likely to positively assist business firms to increase marketing outcomes and performance, and this matter should be confirmed empirically. Finally, a conceptual model presenting relationships among marketing innovation strategy and related constructs is provided.
MULTI-FOCUS IMAGE FUSION METHOD WITH QSHIFTN-DTCWT AND MODIFIED PCA IN FREQUENCY PARTITION DOMAIN

Multi-focus imaging fusion is a technique that puts together a fully focused object from the partly focused regions of several objects from the same scene. For producing a high quality fused image, directional selectivity and invariance characteristics are important. The ringed artifacts, however, were inserted into a fused image because of a lack of invariance and misdirection. A multi-focus image fusion algorithm is proposed to resolve these issues, in conjunction with qshiftN dual-tree complex wavelet transform and modified principal component analysis. First, the source images are translated into the FP domain. It helps in the obtaining of the row frequency components and column frequency components. Then the row-frequency elements and column-frequency elements are combined with a dual tree-complex wavelet qshiftN to transform the origin frames. Dual tree complex wavelet transforms with qshiftN has demonstrated that it provides an effective transformation for multi-resolution imaging fusion with its directional and shift-invariant characteristics. To enlarge the effectiveness of the qshiftN dual-tree complex wavelet transform in frequency partition-based method, the modified principal component analysis (MPCA) algorithm is used. The proposed fusion approach has been tested on a numeral of multi-focus images and compared to various popular methods of imaging fusion. The experimental results indicate that in subjective performance and objective assessment, the proposed fusion approach could deliver better fusion results.
How Does Investor’s Interactive Attention Affect the Stock Market? Some Empirical Evidence

Investor attention has been proved as an important factor affecting stock market variables. Unlike previous studies focusing on search-engine based investor attention, this paper investigates the effect of interactive investor attention based on social media platform. Notably, we extract our proxy via Weibo Hot-word Trends produced by Sina Weibo—the most popular social media platform in China. As a result, we mainly find that interactive investor attention decreases future short-term returns and there is no price reversal. Also, we find significant positive relationships between interactive investor attention and idiosyncratic volatility, breadth of ownership as well as liquidity, indicating that interactive investor attention conveys firm-specific information. Moreover, our results remain unchanged when we conducting different sub-sample analysis.
1.65 Micron (H Band) Surface Photometry of Galaxies. VI. The History of Star Formation in Normal Late-Type Galaxies

We have collected a large body of near-IR (H band), UV (2000 Å), and Hα measurements of late-type galaxies. These are used jointly with spectral evolutionary synthesis models to study the initial mass function (IMF) in the mass range m > 2 M⊙. For spirals (Sa–Sd), Magellanic irregulars (Im), and blue compact dwarfs, our determination is consistent with a Salpeter IMF with an upper mass cutoff Mup ∼ 80 M⊙. The history of star formation and the amount of total gas (per unit mass) of galaxies are found to depend primarily on their total masses (as traced by the H-band luminosities) and, only secondarily, on morphological type. The present star formation activity of massive spirals is up to 100 times smaller than that averaged over their lifetime, while in low-mass galaxies it is comparable to or higher than that at earlier epochs. Dwarf galaxies presently have larger gas reservoirs per unit mass than massive spirals. The efficiency in transforming gas into stars and the timescale for gas depletion (∼10 Gyr) are independent of the luminosity and morphological type. This evidence is consistent with the idea that galaxies are coeval systems, that they evolved as closed boxes, forming stars following a simple, universal star formation law whose characteristic timescale is small (τ ∼ 1 Gyr) in massive spirals and large (τ > 10 Gyr) in low-mass galaxies. A similar conclusion was drawn by Gavazzi & Scodeggio in 1996 to explain the color-magnitude relation of late-type galaxies. The consequences of this interpretation on the evolution of the star formation rate and the gas density per comoving volume of the universe with look-back time are discussed.
Support for teacher candidates and the edTPA

Equipping new teachers in today’s society is a noble and challenging task. Of late, many additional licensing standards for teachers create additional responsibilities for universities that provide pedagogy, knowledge, and content for teacher candidates. Identification of best practices that support teacher candidates on the Educative Teacher Performance Assessment (edTPA) is of interest to many teacher education programs. The purpose of this research was to analyze whether incorporating a mock edTPA had beneficial results on the passage of the edTPA. This study spanned fourteen ten-week quarters and included 688 teacher candidates who were preparing to become certificated teachers at a university in Washington State. The questions that were posited were: a) Does a capstone class requiring a mock edTPA benefit students? b) Which edTPA rubrics are the most challenging, and why are they challenging? This research study found that adding a mock edTPA prior to the student teaching experience did not produce a statistically significant difference in scores when compared to the group who received an embedded curriculum. When comparing the two different time periods, the passing rate was not significantly different and there was little difference in the mean scores of both groups.
Relative adjoint transcendental classes and Albanese maps of compact Kaehler manifolds with nef Ricci curvature

Given a surjective holomorphic map between two compact Kaehler manifolds, we investigate the positivity properties of relative adjoint transcendental classes which are inherited from similar fiberwise properties. As a consequence, we solve a problem proposed by J.-P. Demailly, T. Peternell and M. Schneider concerning the Albanese morphism of Kaehler manifolds with nef anticanonical class.
Shot gun eye injuries: Senegalese experience Journal of Clinical Images and Medical Case Reports

Purpose: To describe the cases of eye trauma caused by the use of home-made and to highlight the difficulties of their manage ment. Observations: We admitted five patients (0.16%) with firearm-relat ed eye injuries during the period from January 01, 2010 to January 01, 2022. All our patients were male. The average age was 33.2 years with extremes between 21 and 55 years. The circumstances of occurrence were dominated by attacks with lead as the main traumatic agent in all our patients. The consultation time ranged from one week to three months with a starting visual acuity not exceeding the light perception. The lesions were bilateral in three patients. There was a loss of eyeball function in all patients. Intraocular foreign bodies were found in 80% of cases. All our patients received medical treatment. Two of our patients had received surgical treatment such as extra capsular extraction and anterior vitrectomy. Discussion and conclusion: Shot-gun eye injuries have increased in recent years. Facial screening makes all the severity of these traumas involving the functional prognosis of the eye. Young people in full em ployment are mainly affected, hence the importance of prevention.
MEAN AND EXTREME RADIO PROPERTIES OF QUASARS AND THE ORIGIN OF RADIO EMISSION

We investigate the evolution of both the radio-loud fraction (RLF) and (using stacking analysis) the mean radio loudness of quasars. We consider how these properties evolve as a function of redshift and luminosity, black hole (BH) mass and accretion rate, and parameters related to the dominance of a wind in the broad emission-line region. We match the FIRST source catalog to samples of luminous quasars (both spectroscopic and photometric), primarily from the Sloan Digital Sky Survey. After accounting for catastrophic errors in BH mass estimates at high redshift, we find that both the RLF and the mean radio luminosity increase for increasing BH mass and decreasing accretion rate. Similarly, both the RLF and mean radio loudness increase for quasars that are argued to have weaker radiation line driven wind components of the broad emission-line region. In agreement with past work, we find that the RLF increases with increasing optical/UV luminosity and decreasing redshift, while the mean radio loudness evolves in the exact opposite manner. This difference in behavior between the mean radio loudness and the RLF in L − z ? > may indicate selection effects that bias our understanding of the evolution of the RLF; deeper surveys in the optical and radio are needed to resolve this discrepancy. Finally, we argue that radio-loud (RL) and radio-quiet (RQ) quasars may be parallel sequences, but where only RQ quasars at one extreme of the distribution are likely to become RL, possibly through slight differences in spin and/or merger history.

International Journal of Instruction

The mental state of teachers is important not only because it affects their own health, but also because it has an impact on the development of the children they teach. In this especially stressful job, resources like social support and mental health help them cope. Our aim is to examine teachers’ mental health, social support, and their interrelationships and whether these are influenced by sociodemographic indicators or harmful addiction. In our descriptive crosssectional, quantitative research, we measured the mental health and social support of secondary school teachers in Szeged (n = 200). It included validated questionnaires used in international surveys. Social support was weaker in our sample, but mental health outcomes were stronger. The social support from smaller settlements was significantly stronger. Respondents with stronger social support were less affected by depression and had a stronger sense of coherence. The research confirmed the relatively good mental health of teachers, which was strengthened by social support, and the latter also correlated with a sense of coherence. The significance of this lies in the fact that the mental health of teachers has an impact on the mental health of their students, and on their own role in health education.
Small-slope approximation for electromagnetic wave scattering at a rough interface of two dielectric

A corona discharge device for use in electrophotography and electrostatic printing apparatuses is provided having a corona discharge electrode, a shielding back plate with a corona discharge aperture and one or more conductive plates. Each of the conductive plates is insulated from the remainder of the apparatus and positioned adjacent to the aperture. A potential is impressed on each of these plates during corona discharge to prevent dust and other foreign particles from entering through the aperture and adhering to the electrode.
THE ECLIPSING SYSTEM EP ANDROMEDAE AND ITS CIRCUMBINARY COMPANIONS

We present new long-term CCD photometry for EP And acquired during the period 2007–2012. The light curves display total eclipses at primary minima and season-to-season light variability. Our synthesis for all available light curves indicates that the eclipsing pair is a W-type overcontact binary with parameters of q = 2.578, i = 83. °3, ΔT = 27 K, f = 28%, and l3 = 2%–3%. The asymmetric light curves in 2007 were satisfactorily modeled by a cool spot on either of the eclipsing components from a magnetic dynamo. Including our 95 timing measurements, a total of 414 times of minimum light spanning about 82 yr was used for a period study. A detailed analysis of the eclipse timing diagram revealed that the orbital period of EP And has varied as a combination of an upward-opening parabola and two periodic variations, with cycle lengths of P3 = 44.6 yr and P4 = 1.834 yr and semi-amplitudes of K3 = 0.0100 days and K4 = 0.0039 days, respectively. The observed period increase at a fractional rate of +1.39 × 10−10 is in excellent agreement with that calculated from the W-D code and can be plausibly explained by some combination of mass transfer from the primary to the secondary star and angular momentum loss due to magnetic braking. The most reasonable explanation for both cycles is a pair of light-travel-time effects driven by the possible existence of a third and fourth component with projected masses of M3 = 0.25 M☉ and M4 = 0.90 M☉. The more massive companion could be revealed using high-resolution spectroscopic data extending over the course of a few years and could also be a binary itself. It is possible that the circumbinary objects may have played an important role in the formation and evolution of the eclipsing pair, which would cause it to have a short initial orbital period and thus evolve into an overcontact configuration by angular momentum loss.
Mitotic Checkpoints and the Role of WEE1 Inhibition in Head and Neck Squamous Cell Carcinoma

Abstract The WEE1 kinase family plays a crucial role in cell cycle regulation and DNA damage response pathways in malignant cells. Inhibition of WEE1 effectively overrides G2 cell cycle arrest and results in the accumulation of extensive DNA damage within dividing cells, potentiating mitotic catastrophe and cell death. As such, the development of WEE1 inhibitors as antineoplastic therapeutics has gained increasing interest in recent years. In particular, the role of WEE1 inhibitors for treatment of head and neck squamous cell carcinomas remains an area of active research with both preclinical and clinical studies investigating their use as both single-agent therapy and chemosensitizers when used in tandem with traditional chemotherapy, particularly in the context of TP53-mutant tumors. Here, we review the relevant available preclinical and clinical data on hand investigating the efficacy of WEE1 inhibitors for the treatment of head and neck cancers.
GROWTH ASPECTS, YIELD AND RUSTS INFECTION FOR SOM WHEAT CULTIVARS AS AFFECTED BY SOWING DATES

A two-year field experiment (1997 and 1998) was carried out to study rusts infection and growth aspects for wheat cultivars (Giza 157 and 161, Gemmiza 1 and Sakha 8 and 69) as affected by sowing dates (5 and 20 November in addition to 5 December). Sowing date resulted in significant effects for all studied characters, except for leaf rust, in 1997, spike length and number of grains / spike over the two seasons. Rusts infection had the lowest records with the earlier sowing date (5/11) in both seasons. The intermediate date of sowing (20/11) exhibited the highest grain yield/ha. , number of spikes m -2 and 100-kernel weight (averaged out 0.14 and 0.44g compared to early and late sowing, respectively). Differences among cultivars were significant for all studied characters, except for 100-kernel weight. Giza 161 cv. highly responded to rusts (29.52 and 51.82% for leaf and stem rusts, respectively) and produced the lowest grain yield/ha (4.47 t). Gemmiza 1 was exposed to lesser leaf and moderate stem rusts infection (5.1 and 19.2% for leaf and stem rusts, respectively as averages of both seasons) and gave the maximum records for spike length and number of grains/spike. Sakha 8 suprassed all cultivars in grain yield/ha. (7.29 t) and number of spikes m -2 (408.74) as averages of both seasons. stem rust in addition to grain yield/ha. over the two seasons. Giza 161 was highly reacted to leaf (58.33%) and stem (64.54%) rusts for early sowing dates, respectively. On the other hand, Sakha 8 produced the highest grain yield (7.93 t/ha.) with the intermediate (20/11) sowing date.
