Complementary therapies for depression: an overview

Depression is one of the most common reasons for using complementary and alternative therapies. The aim of this article is to provide an overview of the evidence available on the treatment of depression with complementary therapies. Systematic literature searches were performed using several databases, reference list searching, and inquiry to colleagues. Data extraction followed a predefined protocol. The amount of rigorous scientific data to support the efficacy of complementary therapies in the treatment of depression is extremely limited. The areas with the most evidence for beneficial effects are exercise, herbal therapy (Hypericum perforatum), and, to a lesser extent, acupuncture and relaxation therapies. There is a need for further research involving randomized controlled trials into the efficacy of complementary and alternative therapies in the treatment of depression.     

Revitalization of the Warren G. Magnuson Clinical Center at the National Institutes of Health

This article is based on research into patients' perceptions of being in hospital. Time, ordinarily taken for granted, becomes a significant problem for people in hospital. Patients seek control over time that they do not seem to have during their stay in hospital. They try to keep track of time and find ways of passing it, while believing that precious personal time is lost to them. The insight gained into differing perceptions of time and how patients coped with these can be used to reduce some of the tensions and negative aspects of the way time is experienced in hospital.     

Stability analysis for discrete linear systems with state saturation by a saturation-dependent Lyapunov functional

This paper concerns the stability analysis problem of discrete linear systems with state saturation using a saturation-dependent Lyapunov functional.We introduce a free matrix characterized by the sum of the absolute value of each elements for each row less than 1,which makes the state with saturation constraint reside in a convex polyhedron.A saturation-dependent Lyapunov functional is then designed to obtain a sufficient condition for such systems to be globally asymptotically stable.Based on this stability criterion,the state feedback control law synthesis problem is also studied.The obtained results are formulated in terms of bilinear matrix inequalities that can be solved by the presented iterative linear matrix inequality algorithm.Two numerical examples are used to demonstrate the effectiveness of the proposed method.

磁场信号检测误差分析及补偿算法

针对载体自身磁场特性及三轴磁传感器误差特性建立了地磁导航干扰误差补偿模型,通过对模型进行简化变形,利用系统辨识的最小二乘估计算法(LS)求取误差特性参数.数据分析表明:该方法简单易实现,简化了复杂的求解过程,基本达到了误差补偿的要求.     

一种保护标价的多属性反向拍卖模型

多属性反向拍卖作为一种电子采购方式已被广泛应用于电子商务中.在大多数拍卖模型中,投标者的标价信息对于拍卖者来说完全公开,在拍卖者和个别投标者共谋情况下,会造成投标者之间的地位不平等,给其他投标者造成经济损失.文中在逼近理想解评标方法和安全多方计算基础上,提出一种保护标价的多属性反向拍卖模型,该模型采用了安全逼近理想解协议,实现标价保密和投标者地位公平,抵御拍卖者与个别投标者的共谋.

基于像素拓展的图形分割与合成的方法研究

提出了一种新的图像分割与合成方法。对于图像的分割,提出了新的分割算法,先是手工将一些明显属于物体和明显属于背景的像素分割出来,然后创建一个小矩形区域进行像素拓展迭代,迭代到图像边界为止。对于图像的合成,采用平均法,设计了新的算法,使物体的基本颜色保持不变的同时,降低了合成图像中从源图像分割的物体与新背景的差异,并使得其饱和度、色度、强度更加自然真实。
