Dick Effect in a Microwave Frequency Standard Based on Laser-Cooled 113Cd+ Ions

The Dick effect is one of the main limits to the frequency stability of a passive frequency standard, especially for the fountain clock and ion dock operated in pulsed mode which require unavoidable dead time during interrogation. Here we measure the phase noise of the interrogation oscillator applied in the microwave frequency standard based on laser-cooled 113^Cd＋ ions, and analyze the Allan deviation limited by the Dick effect. The results indicate that the Dick effect is one of the key issues for the cadmium ion dock to reach expected frequency stability. This problem can be resolved by interrogating the local oscillator continuously with two ion traps.

New Insights into the Depositional Environments of Ordovician Carbonate Formations in the Yubei Area of Tarim Basin Based on Standard Microfacies Types

Objective The Yubei area is located in the mid-east Maigaiti slope of southwestern Tarim Basin, China, with an exploration history of several years. Recent exploration has preliminarily indicated that the Ordovician carbonate formations in this area have some oil and gas potential. Carbonate microfacies provides material basis for reservoir development, seal formation and hydrocarbon generation. Therefore, this work utilized the standard microfacies （SMF） types to study the microfacies of the Ordovician formations in the Yubei area in order to provide theoretical basis for the next exploration.

Pollutant emission reduction effect through effluent tax,concentration-based effluent standard,or both

There are numerous studies comparing different kinds of environmental taxes and standards.However,forms of environmental standards focused by former researchers are usually quantitybased limits/standards(e.g.pounds per day or pounds per unit of output).Concentration-based emission standard(e.g.milligrams per liter of wastewater) as one important form of environmental standard has not been given much attention.In this article,comparable estimates of their probable effect on enterprise pollution reduction will be developed for concentrationbased effluent standards,effluent taxes,and a combination of both.A linear simulation model is used to clearly and obviously compare the effects of effluent taxes and concentration-based standards within the same figure.With one detailed application to the paper industry,some enlightenment and conclusions-as well as the general applicability of these principles-are then provided:Under the same effluent tax rate,enterprises,groups,and industries that are cleaner will reduce more pollutants than those that have higher pollutant abatement costs.It is recommended that effluent taxes are set by avoiding cutting it even at one stroke and considering the feasibility of pollution-reducing technology in various industries.It is necessary to reduce MAC of enterprises to better stimulate enterprises' or industries' emission reduction by preferential measures,such as high tax rate coordinated by speeding up the depreciation of environmental protection equipment.

Attribute-Based Re-Encryption Scheme in the Standard Model

In this paper, we propose a new attribute-based proxy re-encryption scheme, where a semi-trusted proxy, with some additional information, can transform a ciphertext under a set of attributes into a new ciphertext under another set of attributes on the same message, but not vice versa, furthermore, its security was proved in the standard model based on decisional bilinear Diffie-Hellman assumption. This scheme can be used to realize fine-grained selectively sharing of encrypted data, but the general proxy rencryption scheme severely can not do it, so the proposed schemecan be thought as an improvement of general traditional proxy re-encryption scheme.

Development of an Ontology-Based Knowledge Network by Interconnecting Soil/Water Concepts/Properties, Derived from Standards Methods and Published Scientific References Outlining Infiltration/Percolation Process of Contaminated Water

The present work deals with the development of an Ontology-Based Knowledge Network of soil/water physicochemical & biological properties (soil/water concepts), derived from ASTM Standard Methods (ASTMi,n) and relevant scientific/applicable references (published papers—PPi,n) to fill up/bridge the gap of the information science between cited Standards and infiltration discipline conceptual vocabulary providing accordingly a dedicated/internal Knowledge Base (KB). This attempt constitutes an innovative approach, since it is based on externalizing domain knowledge in the form of Ontology-Based Knowledge Networks, incorporating standardized methodology in soil engineering. The ontology soil/water concepts (semantics) of the developed network correspond to soil/water physicochemical & biological properties, classified in seven different generations that are distinguished/located in infiltration/percolation process of contaminated water through soil porous media. The interconnections with arcs between corresponding concepts/properties among the consecutive generations are defined by the relationship of dependent and independent variables. All these interconnections are documented according to the below three ways: 1) dependent and independent variables interconnected by using the logical operator “depends on” quoting existent explicit functions and equations;2) dependent and independent variables interconnected by using the logical operator “depends on” quoting produced implicit functions, according to Rayleigh’s method of indices;3) dependent and independent variables interconnected by using the logical operator “related to” based on a logical dependence among the examined nodes-concepts-variables. The aforementioned approach provides significant advantages to semantic web developers and web users by means of prompt knowledge navigation, tracking, retrieval and usage.

脑卒中全周期康复的思考与策略

脑卒中后患者常会遗留不同程度功能障碍,从医疗机构返回至社区家庭过程中,需要各级医疗机构配合互动、上下转介,形成良好的全周期康复闭环。目前,脑卒中全周期康复的落地应用正逐步推进,但仍存在一些阻力。本文以脑卒中全周期康复理念为基础,结合脑卒中社区康复发展现状,思考脑卒中全周期康复-社区康复环节的发展,强调“社区拐点康复”的重要意义以及基层社区康复标准建立的必要性,重视脑卒中患者康复的全周期阶段,探讨社区基层康复的发展策略,切实提高脑卒中患者社区及家庭生存质量。

The design, development and evaluation of a self-instructional module for nursing practice standards

The purpose of this research was to improve nursing professionals’ understanding of the important link to safe, competent, and ethical practices that Nursing Practice Standards (NPS) serve. This research on NPS may improve the scope and comprehensiveness by which the Standards are integrated with clinical, educational, administrative, and research-based nursing practices. This research was unique in that it includes nurses in developing NPS. The method by which this study was done involved sixteen practicing nurses and seven instructional design experts from Alberta, Canada participating in designing, developing, and evaluating a NPS module. Nursing practice standards are a vital aspect of performing safe, efficient and effective patient care. The manner in which Nursing Standard Practices are presented and taught will directly influence a nurse’s ability to understand the value of NPS and successfully incorporate NPS into practice.

坚持和发展民主集中制原则推进新时代中国刑事诉讼制度现代化

全国人大已将《刑事诉讼法》的修改列入本届人大的工作规划之中。作为规范刑事诉讼程序、约束诉讼主体行为的基本法律,应该明确刑事诉讼中公权力机关之间职能分工的工作原则。民主集中制是我国《宪法》规定的国家机构组织和活动原则,同时也是我国现行刑事诉讼确立的公权力机关之间职能分工的指导原则,具体表现为公检法等机关在刑事诉讼中“分工负责、互相配合、互相制约”的工作原则。民主集中制决定了我国刑事诉讼中权力的集中本位及其分工的相对性。新时代应该发展刑事诉讼中的民主集中制原则,顺应权力本位向权利本位转变的时代潮流,以实现民主集中制原则与刑事诉讼制度的根本自洽,推进刑事诉讼现代化。
