The APS-index and the spectral flow

An equality between the spectral flow of a family $A$ of self-adjoint Fredholm operators and the index of the associated differential operator $\frac{d}{dt}-iA$ with Atiyah-Patodi-Singer-style boundary conditions is shown. This generalizes a result by C.Bar and A. Strohmaier used to show their Lorentzian version of the Atiyah-Patodi-Singer Index Theorem.
Network2Vec: Learning Node Representation Based on Space Mapping in Networks

Complex networks represented as node adjacency matrices constrains the application of machine learning and parallel algorithms. To address this limitation, network embedding (i.e., graph representation) has been intensively studied to learn a fixed-length vector for each node in an embedding space, where the node properties in the original graph are preserved. Existing methods mainly focus on learning embedding vectors to preserve nodes proximity, i.e., nodes next to each other in the graph space should also be closed in the embedding space, but do not enforce algebraic statistical properties to be shared between the embedding space and graph space. In this work, we propose a lightweight model, entitled Network2Vec, to learn network embedding on the base of semantic distance mapping between the graph space and embedding space. The model builds a bridge between the two spaces leveraging the property of group homomorphism. Experiments on different learning tasks, including node classification, link prediction, and community visualization, demonstrate the effectiveness and efficiency of the new embedding method, which improves the state-of-the-art model by 19% in node classification and 7% in link prediction tasks at most. In addition, our method is significantly faster, consuming only a fraction of the time used by some famous methods.
EdgeAI: A Vision for Deep Learning in IoT Era

The significant computational requirements of deep learning present a major bottleneck for its large-scale adoption on hardware-constrained IoT-devices. Here, we envision a new paradigm called EdgeAI to address major impediments associated with deploying deep networks at the edge. Specifically, we discuss the existing directions in computation-aware deep learning and describe two new challenges in the IoT era: (1) Data-independent deployment of learning, and (2) Communication-aware distributed inference. We further present new directions from our recent research to alleviate the latter two challenges. Overcoming these challenges is crucial for rapid adoption of learning on IoT-devices in order to truly enable EdgeAI.
Stable limit theorems on the Poisson space

We prove limit theorems for functionals of a Poisson point process using the Malliavin calculus on the Poisson space. The target distribution is either a conditional Gaussian vector or a conditional Poisson random variable. The convergence is stable and our conditions are expressed in terms of the Malliavin operators. For conditionally Gaussian limits, we also obtain quantitative bounds, given for the Monge-Kantorovich transport distance in the univariate case; and for an other probabilistic variational distance in higher dimension. Our work generalizes several limit theorems on the Poisson space, including the seminal works by Peccati, Sole, Taqqu & Utzet [31] for Gaussian approximation; and by Peccati [32] for Poisson approximations, as well as the recently established fourth-moment theorems on the Poisson space of Dobler & Peccati [7]. Applications to stochastic processes are given.
Retrieve and Refine: Exemplar-Based Neural Comment Generation

Code comment generation is a crucial task in the field of automatic software development. Most previous neural comment generation systems used an encoder-decoder neural network and encoded only information from source code as input. Software reuse is common in software development. However, this feature has not been introduced to existing systems. Inspired by the traditional IR-based approaches, we propose to use the existing comments of similar source code as exemplars to guide the comment generation process. Based on an open source search engine, we first retrieve a similar code and treat its comment as an exemplar. Then we applied a seq2seq neural network to conduct an exemplar-based comment generation. We evaluate our approach on a large-scale Java corpus, and experimental results demonstrate that our model significantly outperforms the state-of-the-art methods.
Testing Cosmic Opacity with the Combination of Strongly Lensed and Unlensed Supernova Ia

In this paper, we present a scheme to investigate the opacity of the universe in a cosmological-model-independent way, with the combination of current and future measurements of an SN Ia sample and galactic-scale strong gravitational lensing systems with SNe Ia acting as background sources. The observational data include the current newly compiled SNe Ia data (Pantheon sample) and a simulated sample of SNe Ia observed by the forthcoming Large Synoptic Survey Telescope (LSST), which are taken for luminosity distances (DL) possibly affected by the cosmic opacity, as well as strongly lensed SNe Ia observed by the LSST, which are responsible for providing the observed time-delay distance unaffected by the cosmic opacity. Focusing on only one specific type of standard cosmological probe, this provides an original method to measure cosmic opacity at high precision. Working on the simulated sample of strongly lensed SNe Ia observed by the LSST in the 10 yr z-band search, our results show that, with the combination of the current newly compiled SNe Ia data (Pantheon sample), there is no significant deviation from the transparency of the universe at the current observational data level. Moreover, strongly lensed SNe Ia in a 10 yr LSST z-band search would produce more robust constraints on the validity of cosmic transparency, with a larger sample of unlensed SNe Ia detected in the future LSST survey. We have also discussed the ways in which our methodology could be improved, with the combination of current and future available data in the gravitational wave and electromagnetic domain.
Coupling 1D stellar evolution with 3D-hydrodynamical simulations on-the-fly II: stellar evolution and asteroseismic applications

Models of stellar structure and evolution are an indispensable tool in astrophysics, yet they are known to incorrectly reproduce the outer convective layers of stars. In the first paper of this series, we presented a novel procedure to include the mean structure of 3D hydrodynamical simulations on-the-fly in stellar models, and found it to significantly improve the outer stratification and oscillation frequencies of a standard solar model. In this work, we extend the analysis of the method; specifically how the transition point between envelope and interior affects the models. We confirm the versatility of our method by successfully repeating the entire procedure for a different grid of 3D hydrosimulations. Furthermore, the applicability of the procedure was investigated across the HR diagram and an accuracy comparable to the solar case was found. Moreover, we explored the implications on stellar evolution and find that the red-giant branch is shifted about $40\, \mathrm{K}$ to higher effective temperatures. Finally, we present for the first time an asteroseismic analysis based on stellar models fully utilizing the stratification of 3D simulations on-the-fly. These new models significantly reduce the asteroseismic surface term for the two selected stars in the Kepler field. We extend the analysis to red giants and characterize the shape of the surface effect in this regime. Lastly, we stress that the interpolation required by our method would benefit from new 3D simulations, resulting in a finer sampling of the grid.
Is the Trotterized UCCSD Ansatz Chemically Well-Defined?

The variational quantum eigensolver (VQE) has emerged as one of the most promising near-term quantum algorithms that can be used to simulate many-body systems such as molecular electronic structures. Serving as an attractive ansatz in the VQE algorithm, unitary coupled cluster (UCC) theory has seen a renewed interest in recent literature. However, unlike the original classical UCC theory, implementation on a quantum computer requires a finite-order Suzuki-Trotter decomposition to separate the exponentials of the large sum of Pauli operators. While previous literature has recognized the non-uniqueness of different orderings of the operators in the Trotterized form of UCC methods, the question of whether or not different orderings matter at the chemical scale has not been addressed. In this letter, we explore the effect of operator ordering on the Trotterized UCCSD ansatz, as well as the much more compact k-UpCCGSD ansatz recently proposed by Lee et al [J. Chem. Theory Comput. , 2019, 15, 311; arXiv, 2019, quant-ph:1909.09114]. We observe a significant, system-dependent variation in the energies of Trotterizations with different operator orderings. The energy variations occur on a chemical scale, sometimes on the order of hundreds of kcal/mol. This letter establishes the need to define not only the operators present in the ansatz, but also the order in which they appear. This is necessary for adhering to the quantum chemical notion of a "model chemistry", in addition to the general importance of scientific reproducibility. As a final note, we suggest a useful strategy to select out of the combinatorial number of possibilities, a single well-defined and effective ordering of the operators.
Prevalence and Correlates of Late-Onset Hypogonadism Among Korean Men Aged 40 Years or Older in Primary Care

Abstract Background: As the population ages, the frequency of late-onset hypogonadism (LOH) has been increasing in primary care. However, there are few data available on the prevalence of LOH among patients of primary care in Asia, particularly in Korea. Methods: To assess the prevalence and associated factors for LOH in primary care, a cross-sectional study was undertaken. A total of 1,235 men aged ≥40 years were consecutively enrolled in this study by 18 family physicians from August 2010 to May 2011. An electrochemiluminescence immunoassay was used to measure the total testosterone levels in morning blood samples. Via a structured self-administered questionnaire, subjects were asked about demographic characteristics and lifestyle. Investigating physicians checked concurrent illnesses and measured patient body mass index and abdominal circumference. Results: The crude prevalence rate of LOH was 16.8% (95% confidence interval [95% CI], 14.7–18.9), which increased with age (p<0.001). It was significantly .
Administration of vitamin D to ameliorate dyspnea of chronic obstructive pulmonary disease patients: a randomized controlled trial

Introduction: As one of the most common causes of human morbidity and mortality, chronic obstructive pulmonary disease (COPD) affects millions around the world. Some evidences have already considered about association between serum levels of vitamin D and COPD. Objectives: This study was aimed to evaluate the effects of vitamin D supplementation on COPD improvement. Patients and Methods: This study was designed as a randomized controlled trial. Forty COPD patients with vitamin D deficiency were enrolled into two groups; cases group who administered vitamin D and control group who received placebo. The severity of dyspnea and spirometric indices were analyzed in both groups. Values were presented as mean and standard deviation (SD) and differences were considered significant at the level of P<0.05. Results: Spirometric indices did not show significant differences before and after vitamin D administration (P>0.05). Dyspnea severity was significantly improved after receiving vitamin D supplementation in comparison with placebo consumption (P=0.03). Conclusion: Spirometric indices were not affected during vitamin D supplementation therapy but it showed a significantly positive effect on the curing of dyspnea. Therefore, adjuvant therapy of COPD using vitamin D supplementation is recommended to better handling of dyspnea in COPD cases.
THE POTENTIAL APPLICATION OF Origanum dubium Boiss. ESSENTIAL OIL AS A SEED PROTECTANT AGAINST BEAN AND TOMATO SEED-BORNE BACTERIAL PATHOGENS

Origanum dubium is a valuable wild oregano species of the natural flora of Antalya, Turkey. In this study, we extracted essential oil (EO) by hydro-distillation of the aerial parts of selected O. dubium chemotype with highest EO content, and analyzed by gas chromatography/mass spectrometry. Carvacrol was the pri- mary component (85.9%) among 24 different compounds in the EO. The volatile test showed minimum inhibitory effect of the EO against Xanthomonas axonopodis pv. vesicatoria, Clavibacter michiganen- sis subsp. michiganensis, Xanthomonas axonopodis pv. phaseoli, Xanthomonas axonopodis pv. phaseoli var. fuscans, and Pseudomonas syringae pv. tomato, at 309, 303, 318, 254, and 901 µL/mL, respectively. A 1-hour treatment of bean and tomato seeds in the volatile phase of the EO effectively sterilized the seeds from bacterial pathogens without inhibiting their germination. To the best of our knowledge, this is the first study on the potential for the use of O. dubium EO as a seed protectant against bean and tomato seed-borne bacterial pathogens.

In Vitro Effect of Temperature on Dentin Bond Strength of Universal Adhesive Systems

The aim of this study was to evaluate the shear bond strength (SBS) of two universal adhesives (Universal Single Bond and All Bond Universal) and a two-step self-etch adhesive system (Clearfil SE Bond) to dentine at various temperatures. Materials and Methods: One hundred and twenty dentin specimens were divided randomly to 12 groups, according to adhesive systems (Universal Single Bond and All Bond Universal, Clearfil SE Bond) and temperature ( 4ºC, 20 ºC, 36ºC, 55ºC) used. Dentin specimens were prepared (n :10, adhesives were applied, and composite cylinders were polymerized. Statistical analysis of the SBS data was performed using Two-way analysis of variance (ANOVA) and Tukey’s Honestly Significant Differences post-hoc test. Results: The Clearfil SE Bond was shown to have higher SBS than the universal adhesives at all temperatures; however, there was no statistically significant difference (P>0.05). In both groups, the lowest SBS values were observed in the samples at 4°C while the highest SBS values were observed in the samples at 55°C. In this case, there was a statistically significant difference (P<0.05). Conclusions: The results suggest that the effectiveness of an adhesive may increase if it is preheated at 36°C or above before use instead of being used immediately after removal from the refrigerator or at room temperature.
STORAGE MEDIA FOR AVULSED TEETH : A REVIEW

Dental avulsion is a common type of trauma that results in the complete displacement of tooth from the alveolar socket. Although the ideal treatment would be the immediate re-implantation of the tooth at the site where the trauma took place, this may not be practically possible in every case. Hence, the avulsed tooth may have to be placed in an appropriate storage or transport medium until it is re-implanted. The biological properties of the storage medium have significant impact on the success of re-implantation, as it must be capable of preserving the vitality, clonogenic and mitogenic ability of the PDL cells for successful re-implantation.

Laparoscopic surgical treatment for ulcerative colitis

Objectives. Laparoscopy is used more widely for the surgery of ulcerative colitis. The objective of this study was a comparison of the surgical and 3-year follow-up results of patients treated with conventional and minimally invasive methods. Materials and methods. A total of 45 patients received surgery for ulcerative colitis, 16 as emergency and 29 as elective cases. Laparoscopy was used in 23 and a conventional method in 22 cases. No difference was found between the two groups from the aspects of American Society of Anesthesiologists physical status (ASA) class, mean body mass index (BMI) and age. There were 4 emergency cases in the laparoscopy group, and 12 in the open group. Nineteen elective surgeries were performed in the laparoscopy group, and 10 in the open group.Results. There was no significant difference between the groups as concerns the length of hospital or intensive care unit (ICU) stay, the time to bowel function recovery, but the duration of open surgery was significantly shorter. There was no difference between the groups in the rate of early postoperative complications, whereas among potential late complications, the rates of intestinal obstruction (8.7% vs. 45%) and a septic condition (0% vs. 27%) were significantly lower in the laparoscopy group. There was a significant improvement in the quality of life after surgery in both groups, and better cosmetic results were observed in the laparoscopy group. Conclusion. Laparoscopy can be used for ulcerative colitis both emergency and elective cases, it provides a good quality of life and the mid-term rate of complications is lower as compared with open surgery.
orporate governance effect on financial distress likelihood : vidence from Spain

The paper explores some mechanisms of corporate governance (ownership and board characteristics) in Spanish listed companies and their impact on the likelihood of financial distress. An empirical study was conducted between 2007 and 2012 using a matched-pairs research design with 308 observations, with half of them classified as distressed and non-distressed. Based on the previous study by Pindado, Rodrigues, and De la Torre (2008), a broader concept of bankruptcy is used to define business failure. Employing several conditional logistic models, as well as to other previous studies on bankruptcy, the results confirm that in difficult situations prior to bankruptcy, the impact of board ownership and proportion of independent directors on business failure likelihood are similar to those exerted in more extreme situations. These results go one step further, to offer a negative relationship between board size and the likelihood of financial distress. This result is interpreted as a form of creating diversity and to improve the access to the information and resources, especially in contexts where the ownership is highly concentrated and large shareholders have a great power to influence the board structure. However, the results confirm that ownership concentration does not have a significant impact on financial distress likelihood in the Spanish context. It is argued that large shareholders are passive as regards an enhanced monitoring of management and, alternatively, they do not have enough incentives to hold back the financial distress. These findings have important implications in the Spanish context, where several changes in the regulatory listing requirements have been carried out with respect to corporate governance, and where there is no empirical evidence regarding this respect. © 2015 ASEPUC.

Application of blue-green algae and mineral fertilizers to direct seeding lowland rice

Fertilizer treatments consisting of cyanobacteria blue-green algae (BGA, Anabaena sp.) combined with nitrogen, phosphorus, and potassium were compared with untreated control rice variety Chainat 1 in greenhouse and field experiments from December 2011 to March 2012. In the greenhouse experiment, application of BGA resulted in significantly higher phosphorus and potassium in seeds compared with the untreated control. BGA significantly increased seed weight, and the difference was 16% compared to 47% between application of NPK 16-16-8+NPK 460-0 (125 kg/ha) of chemical fertilizer and untreated control. In field experiments, the differences between BGA and untreated control for nitrogen, phosphorus, and potassium in seeds and straws were not significant, and application of NPK 16-16-8+NPK 46-0-0 of chemical fertilizer was highest for nitrogen, phosphorus, and potassium in seeds and straws. Application of NPK 16-16-8+NPK 46-0-0 of chemical fertilizer gave the highest straw dry weight, total dry weight, and seed weight, but the treatments gave similar 1000-seed weight. Application of BGA clearly increased growth and yield of rice in a greenhouse, but the effects were not clear in the field. This information is useful for organic rice production.
RESONANT COUPLING OF THE ELECTRON CLOUD WITH THE NUCLEUS IN HEAVY ATOMS

The paper envisages the interaction of the laser radiation with the atomic nucleus in heavy atoms. Within a linearized Thomas-Fermi theory we show that the electron cloud in heavy atoms exhibits giant dipolar vibrations as eigenmodes with a frequency in the range 15ZeV , where Z is the atomic number. These eigenmodes screen to a large extent the electric field of the optical-laser radiation (within the dipolar approximation). At the same time, there may appear a resonant coupling of these modes with the nucleus, which increases considerably the strength of the internal electric field acting upon the electrons and the nucleus. We estimate the effect of this electric field on the atom ionization and the emission rate of nucleons from nucleus and find that, although the nucleon emission rate may be enhanced appreciably, the nucleon emission process is, in fact, stopped by the faster ionization rate, which spoils the resonance regime.
