A priori estimates for Donaldson's equation over compact Hermitian manifolds

In this paper we prove a priori estimates for Donaldson's equation $\omega\wedge(\chi+\sqrt{-1}\partial\bar{\partial}\varphi)^{n-1}=e^{F}(\chi+\sqrt{-1}\partial\bar{\partial}\varphi)^{n}$ over a compact Hermitian manifold X of complex dimension n, where $\omega$ and $\chi$ are arbitrary Hermitian metrics. Our estimates answer a question of Tosatti-Weinkove.Comment: 16 pages. Calculus of Variations and Partial Differential Equations, 201

Patterns of fecal progestagens, estrogens, and androgens associated with reproduction in blue-throated piping guans (Pipile cumanensis)

While fecal hormone analyses are routinely employed to monitor reproduction in mammals, few studies have used these techniques for monitoring reproductive events in birds. This study describes the endocrine patterns associated with reproduction in the blue-throated piping guan (Pipile cumanensis), a less threatened relative of the critically endangered Trinidad piping guan (P. pipile). Fecal samples were collected approximately once a week for 3 years from seven female guans and six male guans at the Saint Louis Zoo. Concentrations of fecal progestagens, estrogens, and androgens were quantified using commercially available enzyme immunoassays. Baseline progestagen concentrations for females ranged from 1.2–1,007.1 ng/g (average ± S.E. = 51.2 ± 3.3 ng/g) and baseline estrogen concentrations ranged from 1.9–3,041.3 ng/g (average ± S.E. = 121.2 ± 7.6 ng/g). Concentrations of both hormones consistently increased prior to egg-laying days, with peak concentrations ranging from 249.7–1,007.1 ng/g for progestagens and 230.2–3041.3 ng/g for estrogens. Fecal androgen levels in males were substantially higher than females and ranged from 10.1–13,326.2 ng/g (average ± S.E. = 709.5 ± 39.2 ng/g. This study is the first one that documents the reproductive physiology of the blue-throated piping guan, and it is one of the few to use non-invasive fecal hormone analyses for monitoring reproduction in birds. The methods outlined here may assist ex situ breeding programs for horned guans and other endangered Cracidae species in the future

Entire solutions to the Monge–Ampère equation

AbstractWe consider the Monge–Ampère equation det(D2u)=Ψ(x,u,Du) in Rn, n⩾3, where Ψ is a positive function in C2(Rn×R×Rn). We prove the existence of convex solutions, provided there exist a subsolution of the form u̲=a|x|2 and a superharmonic bounded positive function φ satisfying: Ψ>(2a+Δφn)n

Status report of CPHS and neutron activities at Tsinghua University

The Compact Pulsed Hadron Source (CPHS) project that was launched in September 2009 at Tsinghua University has reached a first commissioning stage in conjunction with ongoing activities to fulfill the eventual design goal of a ∼1013 n/s epithermal-to-cold neutron yield for education, instrumentation development, and industrial applications. Here, we report the latest progress on the commissioning and applications of 3MeV proton and neutron beam lines in the last one and half years, and the design, fabrication, engineering of the 13 MeV/16kW proton accelerator system

Attentive Aspect Modeling for Review-aware Recommendation

In recent years, many studies extract aspects from user reviews and integrate them with ratings for improving the recommendation performance. The common aspects mentioned in a user's reviews and a product's reviews indicate indirect connections between the user and product. However, these aspect-based methods suffer from two problems. First, the common aspects are usually very sparse, which is caused by the sparsity of user-product interactions and the diversity of individual users' vocabularies. Second, a user's interests on aspects could be different with respect to different products, which are usually assumed to be static in existing methods. In this paper, we propose an Attentive Aspect-based Recommendation Model (AARM) to tackle these challenges. For the first problem, to enrich the aspect connections between user and product, besides common aspects, AARM also models the interactions between synonymous and similar aspects. For the second problem, a neural attention network which simultaneously considers user, product and aspect information is constructed to capture a user's attention towards aspects when examining different products. Extensive quantitative and qualitative experiments show that AARM can effectively alleviate the two aforementioned problems and significantly outperforms several state-of-the-art recommendation methods on top-N recommendation task.Comment: Camera-ready manuscript for TOI
