A wavelet method for unfolding sphere size distributions

The authors consider the problem of estimating the density of the radii of spheres in a medium, based on their observed random cross‐sections. This problem is known as Wicksell's corpuscle problem. The authors first convert Wicksell's integral equation to a form suitable for the application of thresholding wavelet methods to solve ill‐posed integral equations, given noisy data. They then derive the asymptotic properties of their estimators and compare them with other methods available via a Monte Carlo simulation study. They also illustrate their approach with some real data.     

《Coapproxi mationin Locally Convex Spaces》一文的两点注记

一类非线性方程的研究

在一类推广型非线性方程中,应用Leary-Schauder固定点定律建立了通常Sobolev空间Hs和某个权重Sobolev空间。构建一个方程初值。证明了这类推广型非线性方程的求解问题可简化为求解一个完整性连续图形上固定点j。应用Leray-Schauder定理来证明图形上所有固定点j严格在Bx[0,1]组内部存在,且在Bx[0,1]上的每一点是完全连续。其结果表明,该类推广型方程的解能收敛成初值问题的解,即得到了该类推广型非线性方程唯一光滑解。     

邱华栋都市小说中的空间形式

小说是语言的艺术，也是时空的艺术，时空构造制约着人物的塑造和主题的表达。本文将从亨利·勒菲弗的“呈现的空间”和“空间呈现”角度入手，以邱华栋都市小说中的空间形式为个案进行研究，探究邱华栋都市小说中的现代都市空间形式和都市空间的呈现方式，从空间理论的角度揭示其作为真正意义上的都市小说所具有的特质。     

任意Banach空间强伪压缩映射不动点的迭代逼近

利用正规对偶映射的定义，给出了任意Banach空间Lipschitz强伪压缩映射不动点的Ishikawa迭代收敛定理。该定理不仅推广了已知结果，而且还简化了目前相应结果的证明。     

Orlicz-Lorentz模序列空间(Ⅰ)

我们在文[1]中建立了 Orlicz—Lorentz 序列空间并得到了一系列结果.本文用 Orlicz函数列{M■(x)}■=1,代替 Orlicz 函数 M(x),给出了更广泛的一类 Orlicz—Lorentz 模序列空间,并证明了这类空间具有有界完备对称基.     

亚强S—闭空间

本文由强半开渠引进亚强S-闭空间，讨论了亚强S-闭空间的性质，亚强S-闭空间与其它空间之间的联系，它的半正则化空间及亚强S-间空间的强半连续象．     

You Can't Get There From Here: Reaching the Outdoors in Senior Housing

By providing access to outdoor environments, exterior doors can enhance the sense of freedom in residential environments for aging. However, doorways may also present barriers to outdoor access. Using environmental audits, this study examined doorway problems at 68 assisted living facilities in three geographic regions. Results were compared with resident surveys (n = 1,128), staff surveys (n = 432), and resident focus groups (n = 76). Specific doorway issues were found to be associated with residents’ weekly minutes of walking, outdoor usage, and perceived ease of reaching outdoor areas. The main problems were door opening/closing, thresholds and landings, and self-locking doors. The findings indicate that exterior doorways often present barriers to assisted living residents, resulting in lower levels of walking and outdoor use. By discouraging these health-related behaviors, doorway problems may negatively affect residents’ health and well-being. Practice implications suggest that many existing doorway problems, such as high thresholds or excessive opening force, are easily remedied.     

Agentive Spaces,the “Background”, and Other Not Well Articulated Influences in Shaping our Lives

What is special about all our living exchanges with our surroundings is that they occur within the ceaseless, intertwined flow of many unfolding strands of spontaneously responsive, living activity. This requires us to adopt a kind of fluid, process thinking, a shift from thinking of events as occurring between things and beings existing as separate entities prior to their inter‐action, to events occurring within a continuously unfolding, holistic but stranded flow of events, with no clear, already existing boundaries to be found anywhere (Mol & Law, 1994)—a flow of events within which we ourselves are also immersed. We thus become involved in activities within which we find things happening to us, as much as we make things happen in our surroundings—in other words, our surroundings are also agentive in that they can exert “calls” upon us to respond within them in appropriate ways. Consequently, what we can learn in such encounters is not just new facts or bits of information, but new ways of relating or orienting ourselves bodily to the others and othernesses in the world around us—although much can “stand in the way” of our doing this. My concern below is to explore events happening on the (inter)‐subjective side of the Cartesian subject/object divide which “shape” our spontaneous ways of acting in, and reflecting on, the “worlds” within which we live out our lives.     

意象、诗学与认知

意象是人类思维活动中基本而又无处不在的构成要素之一,是象征和思维的认知先决条件。对意象的诗学功能进行研究为了解具有想象能力的心智的认知语义打开了一扇窗。意象是诗歌意义产生中普遍而核心的维度。然而,认知诗学迄今为止在阐释语义及符号机制方面尝试甚微。为深化认知语义符号框架内的诗学意象研究,需在单纯诗学解读和认知研究间建立直接关联,从而关注并探究诗学语篇中意义的产生,而非只是将诗歌作为对认知语义学中某些概念的佐证。
