In this paper, we consider Markov branching processes with killing and resurrection. We first show that the Markov branching process with killing and stable resurrection is just the Feller minimum process which is honest and thus unique. We then further show that this honest Feller minimum process is not only positive recurrent but also strongly ergodic. The generating function of the important stationary distribution is explicitly expressed. For the interest of comparison and completeness, the results of the Markov branching processes with killing and instantaneous resurrection are also briefly stated. A new result regarding strong ergodicity of this difficult case is presented. The birth and death process with killing and resurrection together with another example is also analyzed.

文章于非采暖期(2022年6月1日-8月31日)和采暖期(2022年11月1日-2023年1月31日)在兰州市城关区采集了121个PM_(2.5)样品,并对其中14种重金属元素的污染特征、来源及健康风险进行了研究。结果表明,兰州市采暖期的PM_(2.5)平均浓度((44.1±12.2)μg/m^(3))约为非采暖期PM_(2.5)平均浓度((20.8±3.05)μg/m^(3))的2倍,PM_(2.5)中14种重金属元素的平均浓度在采暖期((4 443±953) ng/m^(3))远高于非采暖期((2 854±426) ng/m^(3)),其中Al、Ca、Fe、Cu和K是兰州市PM_(2.5)中主要的重金属元素。富集因子分析结果表明,受人为活动影响较大的Zn、Se、Cd和Cu在采暖期的EFs值要远远大于非采暖期。正定矩因子分析的结果显示兰州市PM_(2.5)中14种重金属元素主要来源于土壤扬尘、生物质燃烧和工业生产混合排放(39.1%),其次为工业排放(23.3%)、交通排放(20.2%)和燃煤排放(17.4%)。健康风险评价结果显示,所有致癌元素中Cr的致癌风险最高,且在非采暖期和采暖期对成年男性、成年女性和儿童均存在致癌风险,Mn在采暖期对成年男性、成年女性和儿童均存在非致癌风险。因此,兰州市PM_(2.5)中的Cr和Mn的排放需要引起相关部门的高度关注,对于产生这2种元素的煤炭燃烧排放和电镀、冶金、制革和建筑施工等工业生产应该采取一定的措施进行减排监管。总致癌风险和总非致癌风险呈现儿童>成年男性>成年女性的特点。

This paper examines the privatization, implemented by the effects of state-owned enterprises （SOE） Chinese government in the 1990s, on enterprise efficiency for a sample of non-privatized SOEs and privatized ex-SOEs. The study calculates input-oriented DEA meta-frontier efficiency scores, after accounting for heterogeneity in technology across groups. These scores are used to test whether or not one group＇s technology dominates the other. A measure of additional input saving is also provided if these enterprises have access to unrestricted rneta-technology. The analysis of the Chinese pharmaceutical industry reveals that privatization has not improved enterprise efficiency, at least in the short run. Almost 56% of inputs could be proportionally saved if these privatized ex-SOEs had been efficient, relative to the recta-production technology while non-privatized SOEs could proportionally save only 51%. Privatized ex-SOEs had less ability to access to meta-technology. This finding could be explained by subsequent observations that China, at the time of our analysis, did not have well-established intellectual property rights and formal drug approval procedures; these two factors are important driving forces for developing joint ventures with foreign investors to gain additional capital funding and technology transfer. Broadly speaking, our results are consistent with the subsequent shakeup in the Chinese pharmaceutical industry.

Efficient, scalable, bufferless, and compact Ⅲ–V lasers directly grown on(001)-oriented silicon-on-insulators(SOIs) are preferred light sources in Si-photonics. In this article, we present the design and operation of Ⅲ–V telecom nanolaser arrays with integrated distributed Bragg reflectors(DBRs) epitaxially grown on industry-standard(001) SOI wafers. We simulated the mirror reflectance of different guided modes under various mirror architectures, and accordingly devised nanoscale DBR gratings to support high reflectivity around1500 nm for the doughnut-shaped TE01 mode. Building from InP/IngaAs nanoridges grown on SOI, we fabricated subwavelength DBR mirrors at both ends of the nanoridge laser cavities and thus demonstrated room-temperature low-threshold InP/IngaAs nanolasers with a 0.28 μm^2 cross-section and a 20 μm effective cavity length. The direct growth of these bufferless nanoscale Ⅲ–V light emitters on Si-photonics standard(001) SOI wafers opens future options of fully integrated Si-based nanophotonic integrated circuits in the telecom wavelength regime.

Photodynamic therapy(PDT)is a promising approach to treat cancer.1 It involves the use of three individually nontoxic substances to produce a toxic effect.A photosensitizer,when illuminated with light of an appropriate wavelength,will be activated and convert molecular oxygen into reactive oxygen species(ROS),which can then kill tumor *** success of PDT depends on its potency as well as the targeting of the photosensitizer to the tumor site.2 For example,in photoimmunotherapy,the photosensitizer is conjugated to monoclonal antibodies that direct the photosensitizer to tumor cells that express the specific antigen recognized by the antibodies,and the tumor cells are killed upon light irradiation of the tumor site.3 This direct cytotoxicity is useful in treating localized tumor;however,it has limited applicability when metastasis *** this regard,the activation of antitumor immunity appears to be more promising because most cancer patients die,not from localized tumor,but from cancer metastasis and relapse.
