The research on the damage effectiveness assessment of anti-ship missiles involves system science and weapon science, and has essential strategic research significance. With comprehensive analysis of the specific process of the damage assessment process of anti-missile against ships, a synthetic damage effectiveness assessment process is proposed based on the double hierarchy linguistic term set and the evidence theory. In order to improve the accuracy of the expert ’s assessment information, double hierarchy linguistic terms are used to describe the assessment opinions of experts. In order to avoid the loss of experts ’ original information caused by information fusion rules, the evidence theory is used to fuse the assessment information of various experts on each case. Good stability of the assessment process can be reflected through sensitivity analysis, and the fluctuation of a certain parameter does not have an excessive influence on the assessment results. The assessment process is accurate enough to be reflected through comparative analysis and it has a good advantage in damage effectiveness assessment.

发展新质生产力是中共二十届三中全会的重要议题之一,是推动经济高质量发展的关键。新质生产力的本源概念产生于社会转型时期现实问题的需要,经过“酝酿、出场、应用”三个阶段的动态演进,展现出强烈的实践性和时代性。培育新质生产力的关键机理在于以科技创新引领产业创新、以技术创新推动技术应用,构成“劳动者+基础创新+应用创新”的三维实践理路。广阔的国土空间决定了发展新质生产力具体路径的多元性,有必要从抽象走向具体,考察相对微观层面的经验做法。基于新疆尉犁的案例分析表明,推动农业农村领域的新质生产力发展,可以通过数智技术、生物技术来革新农业劳动资料,通过激活乡村土地资源、文化资源、数据资源和生态资源来拓展劳动对象,积极培育和引进优质个体劳动者与协作劳动组织,充分发挥区域资源禀赋。

Urinary incontinence （UI） and erectile dysfunction （ED） are both very prevalent conditions. Insertion of an artificial urinary sphincter （AUS） and penile prosthesis （PP） is an effective and proven method of treatment for both conditions. With advancing age, as well as with increasing populations of patients radically treated for prostate cancer, the occurrence of both conditions found in the same patient is increasing. The purpose of this article was to analyze the available evidence for simultaneous surgical management of male ED and UI using prosthetic devices. The existing literature pertaining to dual implantation of AUS and PP was reviewed. The concomitant insertion of the PP with the male perineal sling was also considered. Concurrent ED and UI are increasingly seen in the post radical prostatectomy population, who are often younger and less willing to suffer with these conditions. Insertion of an AUS and PP, either simultaneously or as a two-stage procedure, appears to be a safe, efficacious and long-lasting method of treatment. The improvements in design of both the AUS and PP as well as the development of the single transverse scrotal incision have made simultaneous insertion of these prostheses possible. Dual implantation of the PP and male sling looks promising in a selected population. In conclusion, the insertion of the AUS and PP for the treatment of concurrent UI and ED is safe and effective. Simultaneous insertion of these prostheses in the same patient offers potential advantages in operative and recovery time and is associated with high patient satisfaction. Combination therapy should therefore be included in the arsenal of treatment of these conditions.

The Scandinavian Prostate Cancer Group- 4 recently reported the long-term survival benefit in men who were randomized to radical prostatectomy versus men watchful waiting for localized prostate cancer.1 The authors have now presented the companion article that updates the long-term quality of life evaluation in these men.2 Given the excellent prognosis of patients with early stage prostate cancer, the impact of therapy on patient＇s quality of life is a significant factor in the optimal management of this disease.

Let H be a Hilbert space with dimH ≥2 and Z ∈ B（H） be an arbitrary but fixed operator. In this paper we show that an additive map （I）： B（H）→ B（H） satisfies Ф（AB） = Ф（A）B = AФ（B） for any A, B ∈ B（H） with AB = Z if and only if Ф（AB） = Ф（A）B = AФ（B）, A, B ∈ B（H）, that is, （I） is a centralizer. Similar results are obtained for Hilbert space nest algebras. In addition, we show that Ф（A2） = AФ（A） = Ф（A）A for any A ∈ B（H） with A2 = 0 if and only if Ф（A） = AФ（I） = Ф（I）A, A ∈ B（H）, and generalize main results in Linear Algebra and its Application, 450, 243-249 （2014） to infinite dimensional case. New equivalent characterization of centralizers on B（H） is obtained.
