In this paper, we have compared the performance of joint network channel coding （JNCC） for multicast relay network using low density parity check （LDPC） codes and Convolutional codes as channel codes while exclusive or （XOR） network coding used at the intermediate relay nodes. Multicast relay transmission is a type of transmission scheme in which two fixed relay nodes contribute in the second hop of end-to-end transmission between base transceiver station （BTS） and a pair of mobile stations. We have considered one way and two way multicast scenarios to evaluate the bit error rate （BER） and throughput performance. It has been shown that when using XOR network coding at the intermediate relay nodes, the same transmission becomes possible in less time slots hence throughput performance can be improved. Moreover we have also discussed two possible scenarios in the proposed system model, in which both diversity and multiplexing gain has been considered. It is worth notifying that BER and throughput achieved for LDPC codes is better than Convolutional codes for all the schemes discussed.

The Songliao Basin in northeast China is one of the largest petroliferous basins worldwide， and features the T2 fault system， consisting of numerous minor extensional normal faults. This study combines high-resolution 3D seismic datasets to detail the characteristics of the T2 fault system， contributing two key findings: (1) The T2 faults are confirmed as polygonal fault systems， characterized by closely spaced， layer-bounded faults with small throws， high dip angles， and random orientations， forming intricate polygonal networks. (2) The study reveals the influence of tectonic stresses on the fault system， showing spatial variations across different tectonic units. In depressions， T2 faults exhibit short lengths， small throws， high density， and multiple directions. In contrast， in inverted anticline belts， they have longer lengths， bigger throws， higher density， and concordant orientations. These variations demonstrate the impact of tectonic inversion on the development of T2 faults. The significance of this research lies in presenting a typical polygonal fault system developed in a deep lake succession and was superposed the influence by regional tectonic stress coeval with its development. The new insights facilitate a reevaluation of the T2 fault system's role in hydrocarbon migration and accumulation within the Songliao Basin.

在当今时代,社会迫切需要设计具有改进的晶体结构、改进的表面形态、孔径和表面积的多功能多孔纳米材料,以满足日益增长的全球能源消耗。为了达到预期的目标,人们对新材料进行了大量的探索。在这方面,层状双氢氧化物(LDHs)和金属有机骨架(MOFs)由于其多样性而受到了社会的广泛关注。不同的方法可以被用来研究晶体和被修饰催化剂的表面性质,如X射线粉末衍射(PXRD)、扫描电子显微镜(SEM)、高分辨率透射电子显微镜、傅立叶变换红外光谱(FT-IR)、X射线光电子能谱分析以及热重分析(TGA)。在这项研究中,通过水热合成的方法得到了泡沫镍(NF)基片上三金属超薄NiCoV层状双氢氧化物(LDHs)纳米片,这是一种非常有效的电极,它能在碱性环境下进行水的有效全分解。纳米片的横向长度约为数百纳米,宽度约为10纳米。从整个摩尔比例来看,摩尔比例为NiCoV-LDHs/NF(6:1:1)电极的效率最高。在1.0 M KOH电解质中,498 mV的中等电位下的OER(析氧反应)和-1.1 V电位下的HER(析氢反应)能达到最佳的催化性能。其短塔菲尔斜率为160和79.0 mV dec-1,进一步体现了该材料优良的性能。值得注意的是,该材料体现出来了优良的持久性和稳定性。碱性条件下,NiCoV-LDHs/NF(6:1:1)电极需要1.55 V的电压能达到10 mA cm-2的电流密度。该优良性能基本上归因于三金属系统的协同作用,并且催化性能会随着工作表面积的增加而提高。本研究提出了一种获得最大经济效益的镍基氢氧化物电催化剂用于全解水的好方法。我们将硝酸镍六水合物与1,3,5-三羧酸连接体和供氮体4,4-联吡啶配体结合,并与氧化石墨烯(GO)配位,制备了基于金属镍的MOF和GO的杂化物(Ni-MOFGO),并将不同含量的GO生长到NF上制备了 Ni-MOFGO/NF杂化物。上述制备的Ni-MOFGO/NF杂化物是一种高活性、高效、稳定的双功能催化剂,对OER和HER具有较高的选择性。Ni-MOFGO/NF杂化碱性介质的电催化性能提高,稳定性高,这是因为其具有大的多孔支架结构,对于电荷载体的输送更为有效。Ni-MOFG06%/NF在析氧反应(OER)的电流密度为0.25mAcm-2,电势为581mV,塔菲尔斜率为51 mV dec-1和析氢反应(HER)的电流密度为50mAcm-2,电势为-1.26V,塔菲尔斜率为72 mVdec-1的条件下,能表现出最佳的催化性能。本研究是以地球丰富的物质为基础,为建立经济、稳健的电催化体系打开了新的大门。

Background: South Asian populations are vulnerable to poor health outcomes associated with climate due to the region’s complex topography, poverty, lack of education, and population density. Physicians, being highly trusted members of society, can help mitigate climate change effects in their countries. Objectives: The present study assessed perceptions of physicians from four South Asian countries (Bangladesh, Bhutan, India, and Pakistan). We hypothesized that physicians from these countries will be aware and knowledgeable about health effects of climate change. Methods: We conducted a cross-sectional online survey of physicians between March and July 2022. Data of 201 physicians was analyzed using the Kruskal-Wallis test and Dunn’s post hoc method. Results: Physicians from four South Asian countries were attuned to the health risks associated with climate change. A majority of physicians (86.6%) believed that climate change would make health conditions in their countries more severe or frequent (Bangladesh 83.3%;Bhutan 70%;India 91% and Pakistan 90.8%). The most common health effect related to climate change was illnesses related to reduced outdoor air quality (54.3%). Common barriers to discuss climate change with patients from all four countries were physicians’ lack of knowledge (strongly agree, 13.8%;agree 47.7%) in how to approach the issue with patients, lack of time (strongly agree, 12%;agree, 48%) and their perception that patients were not interested in knowing about climate change (strongly agree, 8.6%;agree, 42.6%). More than half (56.2%) of the physicians reported no training (Bangladesh, 51.7%;Bhutan, 80%;India, 44.6%;Pakistan, 63.1%) and approximately 30% reported less than 20 hours of training (Bangladesh, 28.3%;Bhutan, 15.0%;India, 39.3%;Pakistan, 27.7%) in climate-change-related health effects. Conclusion: While additional large-scale research is needed to understand the trends observed in our pilot study, our findings identify the need to introdu

Calcium(Ca2+) is an essential nutrient and a cellular signal in plants. The level of free Ca2+in the apoplast is ～10,000-fold higher than that in the cytoplasm at the resting state. This large Ca2+level gradient across the membrane between the interior and exterior can cause Ca2+overload and toxicity. Plants have evolved mechanisms to export Ca2+out of the cytoplasm or store it in intracellular organelles, such as endoplasmic reticulum（ER）, mitochondria, and vacuole.
