Low gas-saturation reservoirs are gas bearing intervals whose gas saturation is less than 47%. They are common in the Quaternary of the Sanhu area in the Qaidam *** to the complex genesis mechanisms and special geological characteristics,the logging curves of low gas-saturation reservoirs are characterized by ambiguity and diversity,namely without significant log response characteristics. Therefore,it is particularly difficult to identify the low gas-saturation reservoirs in the study *** addition,the traditional methods such as using the relations among lithology,electrical property,physical property and gas bearing property,as well as their threshold values,can not effectively identify low gas-saturation *** solve this problem,we adopt the decision tree,support vector machine and rough set methods to establish a predictive model of low gas-saturation reservoirs,which is capable of classifying a mass of multi-dimensional and fuzzy *** to the transparency of learning processes and the understandability of learning results,the predictive model was also revised by absorbing the actual reservoir *** applications indicate that the predictive model is effective in identifying low gas-saturation reservoirs in the study area.

This paper addressed the international transferring t endency of manufacturing industry one by one as follows: (1. The developed count ries realize manufacturing industry structure upgrade reling on worldwide tr ansference not only domestic transference. On one hand, the TNCs make cross-inv estments, transnational merger & acquisition so as to achieve the optimum colloc ation of R&D resources, and obtain innovation in knowledge and technology. On th e other hand, the developed countries transfer labor and resource intensive indu stry as well as the labor-intensive link of the production chain in highly tech nology industry to the developing countries, to make their industrial structure escalation. (2) The adjustment and upgrade of manufacturing industry presents "m ulti-step type". First, the object of international transference substitutes th e capital-intensive industry and maturing industry with complicate technique fo r the industry with labor-intensive, simple technique or higher pollution, or s ubstitutes non-core complex technological procedure and parts and components fo r assembly in manufacturing process. Secondly, technology transference forms "br ain-hand and foot" pattern, i.e. the developed countries are increasingly p aying more and more attention to the research and control of core technology, th us transferring simple technique and labor-intensive procedure in higher scienc e and technology. Thirdly, the developed countries begins to transfer both capit al and technology intensive production, as well as transfer certain procedures i n higher technology production process to a few developing countries, even t o transfer parts of R & D to developing countries. (3) TNCs promote the global m anufacturing network (GMN) by recombination and transfer. TNCs organize producti on, trade, technological research and transference through foreign direct invest ment (FDI) all over the world, as a result, GMN makes the national competence no longer depend on absolu

●AIM:To introduce the macular hole(MH)hydromassage technique as a potentially beneficial approach for the treatment of large or persistent MH.●METHODS:This retrospective observational case series comprised 1. consecutive patients(1. eyes)diagnosed with *** criteria involved a hole aperture diameter larger than 600μm or the presence of an unclosed MH larger than 600μm following the previous *** MH repair procedures were administered in all cases,involving the manipulation and aspiration of the hole margin through the application of water flow with a soft-tip flute needle.A comprehensive assessment was conducted for each case before and after surgery,and optical coherence tomography(OCT)images were captured at every follow-up point.●RESULTS:The mean preoperative aperture diameter was 747±1.6μm(range 61.-1.80μm),with a mean base diameter of 1.90±435μm(range 578-2220μm).Following surgery,all cases achieved complete anatomical closure of MH,with 1. cases(76.5%)exhibiting type 1.closure and 4 cases(23.5%)demonstrating type 2 *** significant differences were observed in the preoperative OCT variables between the two closure *** with type 1.closure showed a significantly improved visual acuity(0.70±0.1.,range 0.50-0.80)compared to those with type 2 closure(0.90±0.1.,range 0.80-1.00,P=0.01.).●CONCLUSION:The MH hydromassage technique demonstrates promising results,achieving acceptable closure rates in cases of large or persistent *** technique may serve as an effective adjunctive maneuver during challenging MH surgery.

There is a long existing "unicorn" problem in Finsler geometry: whether or not any Landsberg metric is a Berwald metric? Some classes of metrics were studied in the past and no regular non-Berwaldian Landsberg metric was found. However, if the metric is almost regular(allowed to be singular in some directions),some non-Berwaldian Landsberg metrics were found in the past years. All of them are composed by Riemannian metrics and 1.forms. This motivates us to ?nd more almost regular non-Berwaldian Landsberg metrics in the class of general(α, β)-metrics. In this paper, we ?rst classify almost regular Landsberg general(α, β)-metrics into three cases and prove that those regular metrics must be Berwald metrics. By solving some nonlinear PDEs,some new almost regular Landsberg metrics are constructed which have not been described before.

Dear Editor,The growing demand for transportation energy has brought increasing challenges to reducing greenhouse gas ***,many countries or regions have proposed solutions to achieve carbon-neutral transportation such as the rapid expansion of the global electric vehicle(EV)***,these benefits are not *** the goal of decarbonization in electricity is achieved,the“pseudo net zero emissions”effect of the transportation sector will inevitably be accompanied by a quiet shifting of carbon responsibility.1.This shift is undoubtedly fatal for both net zero emissions at the national level and carbon responsibility at the industry level;however,the corresponding effects have not yet been clarified.
