Quantitative morphometric analysis of a deep-water channel in the Taranaki Basin, New Zealand

The morphological changes of deep-water channels have an important influence on the distributions of channel sand reservoirs,so it is important to explore the morphological change process of deep-water channel for the exploration and development of deep-water oil and gas.Based on a typical sinuous Quaternary channel(Channel I)in the Taranaki Basin,New Zealand,a variety of seismic interpretation techniques were applied to quantitatively characterize the morphological characteristics of the Channel I,and the relationships between the quantitative parameters and the morphological changes of the Channel I,as well as the controlling factors affecting those morphological changes,were discussed.The results are as follows:(1)in the quantitative analysis,six parameters were selected:the channel depth,width,sinuosity,and aspect ratio(width/depth),the channel swing amplitude(λ)and the channel bend frequency(ω);(2)according to the quantitative morphological parameters of the channel(mainly including three parameters such as channel sinuosity,ωandλ),the Channel I was divided into three types:the low-sinuous channel(LSC),the high-sinuous channel(HSC),the moderate-sinuous channel(MSC).U-shaped channel cross-sections developed in the LSC,V-shaped channel cross-sections developed in the HSC,including inclined-V and symmetric-V cross-sections,and dish-shaped channel cross-sections developed in the MSC;(3)the morphological characteristics of the LSC and MSC were related to their widths and depths,while the morphology of the HSC was greatly affected by the channel width,a change in depth did not affect the HSC morphology;(4)the morphological changes of the Channel I were controlled mainly by the slope gradient,the restricted capacity of the channel and the differential in fluid properties.

In the trend of globalization,digitization,and economic integration,human resources are the core competitiveness of enterprises,and cultivating and developing them is crucial for enhancing competitive advantages.This article delves into how human resource development drives enterprise innovation,promotes team collaboration,and optimizes performance management.Currently,although many enterprises are beginning to attach importance to human resource development,they still face problems such as insufficient investment,weak targeted training,and insufficient exploration of employee potential.Therefore,it is proposed that in the new situation,enterprises need to strengthen diversified training strategies,use digital tools to improve training efficiency,build a fair performance evaluation system,stimulate employee potential,and promote internal talent mobility.The implementation of these strategies will effectively enhance the efficiency of enterprise human resource management and consolidate market position.

The New “Waterways and Sea Canals” Strategy in the “Continent of Asia” and Its Implications on the Global Map

This paper reviews a strategic scientific proposal to dig and construct three navigable sea lanes linking isolated inland seas and blocked side bays and linking it with the open seas, to facilitate the movement of free trade and international navigation, and to break the captivity of geographically isolated environments, and to give a strategic advantage to some areas and sectors that are neglected politically, socially, economically and environmentally, and to adopt the strategy of establishing a marine channel between the “Caspian Sea” and the “Black Sea” through the “lands belonging to Russia”. On digging a navigational canal at the lowest cost in a plain area within the territory of Russia, with a length of approximately 600 kilometers (616 km), starting from the nearest bay in the Caspian Sea, passing near the city of “Pyatigorsk” to the city of “Sochi” on the Black Sea, while it comes: -The strategy of the waterway and the sea channel between the “Caspian Sea” and the “Arabian Gulf” through the “lands belonging to Iran” by digging and cutting a path in the rocks with a width of 100 meters and a length of about 700 kilometers, and at a time rate of less than 10 years, and this project will liberate all countries in the Caspian Sea, and the study concludes with the strategy of the navigational channel between the “Arabian Gulf” and the “Mediterranean Sea” through the two countries of “Iraq-Syria”, with a length of about 1350 km, and the world will benefit in the security, commercial and political fields.

The analysis on reservoir sediment deposition and downstream river channel scouring after impoundment and operation of TGP

According to the measured data after impoundment and operation of the Three Gorges Reservoir,the reservoir sediment deposition and downstream river channel scouring are described briefly and compared with the research results achieved in the demonstration stage.It is indicated through analysis that the reservoir sediment deposition and downstream river channel scouring during 8-year impoundment and operation are still within the original forecast,so the original forecasting results are feasible.The further observation and comparison should be conducted because the comparison between the observed data and the original forecast is not so sufficient in time and the prototype observation and related research work should be strengthened in the future.

Responses of river bed evolution to flow-sediment process changes after Three Gorges Project in middle Yangtze River:A case study of Yaojian reach

The Three Gorges Project(TGP)has changed the flow-sediment process in the middle Yangtze River.For navigation purposes,there is an urgent need to study the changes of the river regime over a long-term period and the shoal-channel evolution over different seasons since the completion of the TGP.Based on analysis of the measured data and the results of a two-dimensional mathematical model,the changes of the river regime and river bed evolution in the Yaojian reach downstream of the TGP were studied.Results show that a high sediment transport flux helps to keep the main flow in the North Branch,while a low sediment transport flux helps to keep the main flow in the South Branch.Thus,the main branch will not change in the near future because of the low sediment transport load.In this study,the flow-sediment process adjusted by the TGP was restored to the conditions before the TGP,and the river bed evolution under the adjusted and non-adjusted flow-sediment conditions was calculated.After the completion of the TGP,the reservoir storage accelerated the flood recession process and decreased the erosion by 11.9%under the flow-sediment conditions in 2010,and the deposition in the flood season decreased by 56.4%.

A Statistical Theory of Language Translation Based on Communication Theory

We propose the first statistical theory of language translation based on communication theory. The theory is based on New Testament translations from Greek to Latin and to other 35 modern languages. In a text translated into another language, all linguistic variables do numerically change. To study the chaotic data that emerge, we model any translation as a complex communication channel affected by “noise”, studied according to Communication Theory applied for the first time to this channel. This theory deals with aspects of languages more complex than those currently considered in machine translations. The input language is the “signal”, the output language is a “replica” of the input language, but largely perturbed by noise, indispensable, however, for conveying the meaning of the input language to its readers. We have defined a noise-to-signal power ratio and found that channels are differently affected by translation noise. Communication channels are also characterized by channel capacity. The translation of novels has more constraints than the New Testament translations. We propose a global readability formula for alphabetical languages, not available for most of them, and conclude with a general theory of language translation which shows that direct and reverse channels are not symmetric. The general theory can also be applied to channels of texts belonging to the same language both to study how texts of the same author may have changed over time, or to compare texts of different authors. In conclusion, a common underlying mathematical structure governing human textual/verbal communication channels seems to emerge. Language does not play the only role in translation;this role is shared with reader’s reading ability and short-term memory capacity. Different versions of New Testament within the same language can even seem, mathematically, to belong to different languages. These conclusions are everlasting because valid also for ancient Roman and Greek readers.

Classification of River Reaches on the Little Disturbed East Alligator River, Northern Australia

The East Alligator River drains a 7000 km2 catchment in northern Australia comprised largely of Aboriginal land and has a very low average population density of about 0.15 persons per km2. River reaches were classified according to geomorphic features on both the East Alligator River and its major tributary, Magela Creek, next to which is located the Ranger uranium mine. Sixteen reaches were described for the 241.4 km of the East Alligator River and ten reaches were described for the 118.8 km of Magela Creek. The dominant river types on the East Alligator River were various types of anabranching rivers, sandstone gorges and cuspate tidal meanders. On Magela Creek the dominant river types were wetlands and channel billabongs, island anabranching and sandstone gorges. It is unusual for anabranching rivers and gorges to be so dominant. Current river classification schemes could not accommodate all the various river types and need to be modified so that tidal channels are covered in more detail and so that the classification of anabranching rivers recognises that sand-bed varieties occur in partly confined valley settings.

Theory of Byuon and Pharmaceuticals of the Future

The article considers the quantum information channel (QIC) described by the byuon theory (BT)—the theory of the appearance of the world around us: physical space, the world of ultimate particles, living matter etc., based on the interaction of non-observable objects (the byuons) nature. The information transporter in the QIC is object 4b (four contact interaction of the four vacuum states of the byuon), carrying information about the information image of the object in physical space—a quantum medium formed by objects 4b. The article proposes a hypothetical model explaining the effects of ultra-high dilutions of chemical and biological substances (UHDS), the search for the physical nature of the action of which is currently underway. UHDS could be the base of the pharmaceutical industry of the future.

基于复数生成对抗网络的5G OFDM信道估计方法

准确的信道估计能够显著地降低误码率(bit error rate,BER),提高无线通信效率和质量,是5G OFDM通信系统接收机设计的关键环节之一。基于最小二乘(least square,LS)法和基于最小均方差(minimum mean square error,MMSE)的信道估计方法利用系统稀疏性计算信道响应矩阵,但LS算法计算精度较低,而MMSE算法计算量过大。为提升估计精度,业界设计了基于深度学习的信道估计方法。然而,现有的深度学习方法将复数矩阵拆分成实部和虚部,没有充分提取信道中的复数特征,造成估计的信道响应矩阵出现失真。为此,设计了一种基于复数的生成对抗网络模型,充分提取信号的复数特征,从而更准确地估计5G新空口(new radio,NR)标准的物理下行链路共享信道(physical downlink shared channel,PDSCH)的信道响应矩阵。为了验证所提方法的有效性,将所提方法分别与LS算法、实际信道估计、超分辨率神经网络、残差神经网络信道估计算法进行了对比分析。结果表明,当估计的信道响应矩阵与真实矩阵之间的均方差达到0.01时,采用所提方法实现的无线通信系统的信噪比高于现有方法5 dB左右。

Channel evolution under changing hydrological regimes in anabranching reaches downstream of the Three Gorges Dam

Elucidating the influence of dams on fluvial processes can benefit river protection and basin management. Based on hydrological and topographical data, we analyzed channel evolution in anabranching reaches under changing hydrological regimes influenced by the Three Gorges Dam. The main conclusions are as follows： 1） the channels of specific anabranching reaches were defined as flood trend channels or low-flow trend channels according to the distribution of their flow characteristics. The anabranching reaches were classified as T1 or T2. The former is characterized by the correspondence between the flood trend and branch channels, and the latter is characterized by the correspondence between the flood trend and main channels; 2） on the basis of the new classification, the discrepant patterns of channel evolution seen in anabranching reaches were unified into a pattem that showed flood trend channels shrinking and low-flow trend channels expanding; 3） flood abatement and the increased duration of moderate flow discharges are the main factors that affect channel adjustments in anabranching reaches after dam construction; and 4） in the next few decades, the pattern of channel evolution will remain the same as that of the Three Gorges Dam operation. That is, the morphology will fully adapt to a flow with a low coefficient of variation. Our results are of interest in the management of the Yangtze River and other rivers influenced by dams.

Flow resistance adjustments of channel and bars in the middle reaches of the Yangtze River in response to the operation of the Three Gorges Dam

Since the Three Gorges Dam(TGD)was put into operation,the flood water level at an identical discharge rate has not displayed a decreasing trend along the middle reaches of the Yangtze River(MYR).The flow resistance variations of the channel and bars in response to the operation of the TGD remain poorly understood,despite the importance of understanding these for water disaster mitigation and water environment regulation.Herein,the impacts of the TGD on the downstream flow resistance of the channel and bars in the MYR were analyzed using systematic surveys of hydrological datasets,cross-sectional profiles,sediment datasets,and remote sensing images,during different periods.Under the actual natural conditions in the MYR,a modified semi-empirical formula,which considered the grain,dune resistance,as well as the topographic features of the riverbed,was proposed to predict the channel resistance.Furthermore,the effect of various dam-control flow and sediment elements on the variation in different flow resistance components,and the corresponding relationships among them were investigated.Results showed a decline in the comprehensive,channel,and bar resistances as the discharge increased,whereas there was a slight increase when reaching the bank-full discharges.Notably,the bar resistance occupied 65%,while the channel resistance,in which dune resistance was much larger than grain resistance,contributed 35%to the comprehensive resistance.In addition,while flow resistance rose over time,there was a decline as the distance from the TGD increased.In conclusion,the increased dune and bar resistances,interpreted by the fluctuated channel longitudinal profile and growing vegetated area on bars,were the dominant factors preventing the flood water level from dropping.

Development of E-banking channels and market share in developing countries

There is fierce global competition within the banking industry.Therefore,banks endeavor to grow and strive to increase their market share.We analyzed the effect of developing innovative channels of presenting bank services on banks’market share.The statistical population of this research was Shahr bank’s central headquarter and its branches in Tehran,Iran.We developed questionnaires for gathering the data.The validity and reliability of the scales were tested by EFA,CFA,experts’opinion,and Cronbach’s alpha.We used linear regression to assess the impact of innovative channels,including internet banking,automatic teller machines(ATMs),mobile banking,telephone banking(TB),and point of sales(POS)on banks’market share.The results indicated that some of these channels,including internet banking,POS,and TB,positively affect a bank’s market share.The effect of two other platforms,including mobile banking and ATM development,on banks’market share was rejected.The findings of this study expand our understanding of how bank managers can improve their market share by developing innovative e-banking channels.

The Relationship Between New Ion Channels and Ectopic Discharges From a Region of Nerve Injury

Changes in ectopic discharges from axons in an injured nerve were examined while agents that interact with ion channels were applied to the site of the nerve injury. Tetraethylammonium (TEA) greatly facilitated spontaneous ectopic discharges or evoked ectopic firing in previously silent axons.Tetrodotoxin, an Na^+ channel blocker,completely blocked spontaneous discharges.Verapamil, La3^+, and Mn2^+, agents that interact with Ca2^+ channels,blocked spontaneous discharges and depressed the responses evoked by TEA, noradrenaline and high concentration of K^+.Increasing Ca2^+ levels facilitated ectopic discharges and this effect was blocked by La3^+ and Mn2^+. Normal axons (from uninjured nerves) were insensitive to all the effects seen in the axons from the injured nerve.These results suggest that following nerve injury the membrane of the regenerating sprout contains new ion channels, particularly Ca2^+ channels, anti that these channels are responsible for the generation of ectopic discharges.

体验经济背景下新零售供应链渠道选择策略研究——以BOPS全渠道参与者的博弈视角

近年来,随着体验经济的兴起以及消费者需求多样化和碎片化等特点,零售企业为提升运作效率积极探索新的转型方向,开通了多种新零售模式。其中,“线上下单,线下取货”(BOPS)模式作为新零售渠道融合的经典模式,能够实现电商平台和线下实体店之间用户流量转化、库存信息共享,以及满足消费者在不同场景下的一站式购物需求。文章通过梳理新零售理论与发展趋势,阐述新零售相关概念及供应链运作过程中存在的问题,分析传统零售与新零售之间的差异性。在新零售实践背景下,基于顾客体验效应构建双渠道和全渠道供应链博弈模型,重点探究供应链成员渠道选择策略,以及不同情形下最优定价与体验投资决策。研究发现:与传统双渠道相比,实施全渠道策略并不总是有利的,决策者要清楚消费者选择全渠道模式的真正动机。在满足参数约束的情形下,全渠道策略的开通有利于供应链参与者挖掘新的消费市场,并通过差异化定价方式提升系统利润。研究提出了新零售运营管理方面的政策建议,零售企业应打破线上线下的界限,构建无缝的用户体验,加强数字化技术的投入,与供应商建立长期稳定的合作关系,共同优化供应链流程,实现供应链协同效应。

冲刷及整治工程叠加作用下武汉河段滩槽调整特征与成因

大型水库的修建引起了坝下游的滩槽调整,进而对河势、航运、防洪及生态等产生显著影响。为探究滩槽调整的驱动机制,采用1952—2022年水沙和1959—2021年地形观测资料,以长江武汉河段为例,分析了床沙组成、来水来沙及整治工程等因素的影响。研究表明:①武汉河段枯水河槽冲刷量占全河槽冲刷量的90.4%,断面趋向窄深化,河相系数减小。不同江心洲及汊道冲淤出现差异性调整,2001—2021年,铁板洲和白沙洲洲体面积分别减少了63.1%和61.5%,潜洲和天兴洲洲体面积分别增大了212.3%和14.5%;2013年后,铁板洲左右汊均冲,天兴洲汊道左淤右冲。②来沙量锐减,河床以0.125 mm≤d<0.25 mm的细沙居多,抗冲性较弱,是冲刷加剧的先决条件;三峡水库的削峰补枯作用加剧了枯水倾向汊河的冲刷幅度;整治工程改变了滩槽冲淤的横向分布,是江心洲差异性调整的主导因素,也是天兴洲保持左淤右冲的重要原因。③三峡水库蓄水前,洲滩之间演变联动性强;三峡水库蓄水后,来沙减少和中水期时间延长导致洲滩冲刷萎缩,洲滩之间演变联动性变弱;整治工程实施后,工程保持了心滩稳定且其缓流滞沙效应提高了抗冲性,心滩淤长的同时限制了边滩发育,叠加来沙进一步减少,边滩之间、心滩之间演变联动性进一步变弱,边滩与心滩之间演变联动性再次增强。
