信号源功率不一致对MUSIC算法分辨性能的影响

该文首先定义了用以度量MUSIC算法分辨性能的平均信噪比分辨门限,并给出它的表达式。然后通过数据模拟得知,功率不一致会降低MUSIC算法的分辨能力;在一定条件下,功率不一致对MUSIC算法分辨性能的相对影响与其他参量无关。该文还讨论了功率不一致对阵元数、快拍数和两信号源方位参数绝对差的影响。

基于改进MUSIC算法的宽带信号DOA估计

现有的波达方向(DOA)估计算法在估计被动探测系统中的宽带信号方位时,存在DOA估计结果偏差大、运算复杂度高等问题,难以满足信号实时处理的要求。为提高多源信号DOA估计的空间分辨率,提出一种基于S变换且不需要预估信号源个数的多重信号分类改进算法。根据宽带信号的频域特征,利用S变换处理阵列接收信号,得到多分辨的时频谱矩阵,同时构建时频域的阵列信号数据模型,结合信号功率谱矩阵呈联合对角化结构的特点,设计基于S变换的子空间谱估计公式。在此基础上,通过谱峰搜索进行DOA估计,实现多源宽带信号的声源定位。仿真结果表明,在信噪比范围为-15~10 dB的条件下,该算法的估计成功率始终保持在90%以上,相比TCT、CS_TCT、CWT_MUSIC算法,其具有较优的估计性能,并且无需预估信号源数。

Individualized music for dementia:Evolution and application of evidence-based protocol

The theory-based intervention of individualized music has been evaluated clinically and empirically leading to advancement and refinement of an evidence-based protocol, currently in its 5th edition. An expanded version of the protocol was written for professional health care providers with a consumer version tailored for family caregivers. The underlying mid-range theory is presented along with a seminal study that was followed by further research in the United States, Canada, Great Britain, France, Sweden, Norway, Japan and Taiwan. Key studies are summarized. Given its efficacy when implemented by research staff, studies have advanced to testing the intervention under real-life conditions when implemented and evaluated by trained nursing assistants in long-term care facilities and visiting family members. In addition, one study evaluated the implementation of music by family members in the home setting. Initial research focused on agitation as the dependent variable with subsequent research indicating a more holistic response such as positive affect, expressed satisfaction, and meaningful interaction with others. The article advances by describing on-line programs designed to train health care professionals in the assessment, implementation and evaluation of individualized music. In addition, Gerdner has written a story for apicture book intended for children and their families(in press). The story models principles of individualized music to elicit positive memories, reduce anxiety and agitation, and promote communication. The article concludes with implications for future research.

EEG Analysis of the Contribution of Music Therapy and Virtual Reality to the Improvement of Cognition in Alzheimer’s Disease

Alzheimer’s disease is the most common form of dementia, affecting nearly 9.9 million new people every year. The disease provokes important memory and cognitive impairment, eventually causing individuals to forget their loved ones and rendering them completely dependent on their caretakers. Alzheimer’s patients typically experience more negative emotions, such as frustration and apathy, than healthy older adults. There is currently no cure for the disease. Our research group explores how the integration of virtual reality (VR) and an EEG-based intelligent agent in music therapy can alleviate psychological and cognitive symptoms of the disease. We propose a theory explaining how, through activation of the brain reward system, music can reduce negative emotions, increase positive emotions and as a result increase performance on cognitive tasks. The results of our experimental study concord with our theory: emotional states of participants are improved, as per recorded through EEG, and performances on memory tasks show improvement following the intervention. We believe that the combination of EEG brain assessment, VR and music therapy is a promising method for emotional states and cognitive symptoms of Alzheimer’s disease.

Musical Urbanism between Radicalism and Tradition： A Reflection on the Architectural Discourse of the 1920s

In the aftermath of the First World War, various compositions emerged that explored the phenomenon of the modem city by translating the clamorous sounds of urban environments and reflecting them artistically in the medium of music. With the rendering of poetic and esoteric moods unrelated to practical life considered outdated, musical preoccupation with modem architecture mostly concemed social aspects, such as people＇s circumstances, their emotional rootedness to bygone conditions and the search for orientation in an environment characterized by technology. There is a parallel here with contemporary architectural debates in which tension between modernism and traditionalism also played a key role.

The Effect of Music Therapy for Patients With Huntington＇s Disease： A Systematic Literature Review

Huntington＇s disease is a progressive, neurodegenerative, and autosomal dominant disease characterized by motor- and psychiatric disturbances, and cognitive decline. Since there is no cure, all treatment is aimed at improving quality of life. One form of non-drug therapy which is barely recognized, is music therapy. The literature on its use and effect in patients with Huntington＇s disease is limited. We therefore performed a detailed literature survey in order to delineate the different types of music therapy interventions and their aims. Music therapy studies were included when targeting： （1） motor disturbances; （2） cognitive disturbances; （3） psychiatric disturbances; and （4） emotional/social disturbances. A total of eight studies that met these criteria were analyzed. We found that music therapy interventions vary throughout the different stages of the disease and are not yet applied optimally. Not the stage of the disease but the individual treatment goals seem to be more determinative for the music therapy indications. In conclusion, precise aims and methods in relation to the stage of the disease are not well determined. There is a need for systematic study of this treatment option.

The Reception of Anton Bruckner's Music in China

In the early days after China opened to the outside world in the 1980s,numerous works by well-known European composers were frequently performed on Chinese stages and were well received by audiences.Anton Bruckner’s symphonic works,however,were not performed as frequently as some others during that era,due to length,complex musical structure,and difficulties.This paper discusses the reception of Anton Briclner’s Music in China.

Effectiveness of music intervention on cognitive function and neuropsychiatric symptoms in the elderly with dementia:a meta-analysis

Dementia is increasing dramatically with an increasing elderly population.Pharmacological interventions are proven to have limited efficacy to treat many of the features of dementia.In such a situation,non-pharmacological means become important to help people with dementia,especially music therapy.The efficacy of music intervention on cognition has been barely explored in the literature,and the few studies that are available present inconsistent results.The aim of this systematic review is to have a meta-analysis on the effect of music therapy for improvements in cognitive functions as well as neuropsychiatric symptoms in the elderly with dementia.

Jordan＇s King Hussein＇s Peace Initiative and the Treaty with Israel： Overcoming Domestic and Foreign Pressures

The Wadi ＇Araba peace treaty which Jordan＇s King Hussein signed with Israel on October 26, 1994 became a target of criticism ever since it became known to the Jordanian public. Intense pressure was exerted on the Jordanian government to revoke the treaty even before its signature. The opposition to it reached its peak in the following year, when the tension in the holy sites in Jerusalem mounted. Given the persistence of the Arab-Israeli conflict and the fact that the Palestinian issue remained unresolved, it was clear that the King was aware of the potential danger of signing a peace accord with Israel, and that he was prepared to face criticism not only from the Arab states but also from nationalists, Islamists and Leftists all of whom disapproved of his decision. Yet the King remained undeterred and boldly carried on the discussions that culminated in the peace treaty＇s signature. Bearing in mind the fact the Egypt was the first country to sign a peace treaty with Israel it seemed as if there was little risk involved in the normalization process, and that the opposition to the treaty would soon subside. As it turned out, however, the pressure to abrogate it continues to mount.

＂From a Utopia to a Dystopia＂ On Mark Twain＇s Compliance with and Deviation from Heterotopology in A Connecticut Yankee in King Arthur＇s Court

In this paper, the author intends to parallelize Mark Twain＇s A Connecticut Yankee in King Arthur＇s Court with Foucault＇s theorizations about heterotopia, or heterotopology. For Foucault, heterotopia is a paradox because it is paces that are both real and placeless. Twain＇s novel is a time travel story, which juxtaposes the temporalities of the 6th and 19th centuries. In the story, Hank, the hero, is allowed access to Camelot, King Arthur＇s court. Above all, he has introduced to it quite a few elements of modem technology and civilization. So far Twain seems to have complied with Foucault＇s heterotopology. That is, there is a textual heterotopia created in his novel. However, the last principle of Foucault＇s heterotopology states that a heterotopia can be comparable to a utopia because of its contrastive function. A typical time travel story has the same contrastive function as well. That is, in either case there should be a utopia, a dystopia, or a mixture of them. However, Twain＇s novel fails to contrast the 6th century with the 19th century simply because the heterotopia Hank has created leaps from a utopia to a dystopia. It is at this point where Twain has deviated from heterotopology. The shifting nature of this heterotopia not only disables its contrastive mechanism but also jeopardizes its thematic clarity. Most of all, it indicates that Twain has a considerably ambivalent attitude towards the industrial civilization, and that as a consequence, he is indecisive about the direction of this novel.

Re-Formulation of Mean King’s Problem Using Shannon’s Entropy

Mean King’s problem is formulated as a retrodiction problem among noncommutative observables. In this paper, we reformulate Mean King’s problem using Shannon’s entropy as a first step of introducing quantum uncertainty relation with delayed classical information. As a result, we give informational and statistical meanings to the estimation on Mean King problem. As its application, we give an alternative proof of nonexistence of solutions of Mean King’s problem for qubit system without using entanglement.

Effects of Physical Exercise and Music Therapy on Cognitive Aspects in Tunisian Patients with Mild Alzheimer’s Type Dementia

Aim: The objective of this research is to highlight the effectiveness of physical exercise and music therapy in older patients with Alzheimer’s disease (AD). Methods: Patients with a mild level of AD were included in this study, divided into the therapy group (TG;N = 30, aged 68 ± 3.2 years) and the control group (CG;N=30, aged 65 ± 2.6 years). The therapy group was enrolled in an exercise-training program (walking, resistance and balance exercises) combined with musical therapy for 10 weeks (three sessions of 60 minutes per week). The Control group was instructed to follow their daily rhythm of life (e.g., rest, reading) under the same conditions. The intervention program was enrolled under the supervision of;one psychologist;a neurologist;two music therapists, and two physiotherapists, all belonging to the same hospital unit. After 10 weeks of participation in the combined program, cognitive parameters were improved in the therapy group measured with the Behavior Pathology in Alzheimer Disease (BEHAVE-AD), (p < 0.05) for activity disturbance, diurnal rhythm disturbances, anxieties and phobias, affective disturbance. The percentage range of improvements is 1.07% to 2.96%. Results: Our results demonstrate that physical exercise combined with music therapy improves cognitive function in patients with Alzheimer’s disease. Conclusions: Physical exercise and music therapy are beneficial combined treatments for improving life quality in older patients. This approach may be useful to help patients with a mild level of Alzheimer’s disease improve their behavioral and psychological parameters.
