DisCnet: Pixel segmentation based on discrete features
Authors: Li Zhihui , Jia Xiaoshuo
Published: September 2022

In the process of pixel-level semantic segmentation tasks, traditional image processing algorithms will suffer from the working mechanism of convolutional layers and pooling layers, resulting in the loss of some features, which now leads to inaccurate semantic segmentation accuracy. For such problems, we design a discrete pooling layer by analyzing the distribution and statistical properties of discrete data. Compared with the traditional pooling layer, the discrete pooling layer can not only preserve the spatial information of features, avoid the loss of features, but also can efficiently improve the accurate segmentation of instance images. Then, based on the discrete pooling layer, we design DisCnet in combination with the convolutional layer. Finally, DisCnet is compared with some state-of-the-art algorithms under the Cityscapes dataset. Experiments demonstrate that DisCnet achieves excellent results in both accuracy and speed.

Research on The Similarities and Differences Between Graduation Exhibition and Art Exhibition
Authors: Chen Qiuhong
Published: September 2022

A complete work of art is composed of three parts: the artist's conception, the work and the viewer's perception. The absence of either side will make it impossible for the author and the audience to empathize and communicate. Graduation exhibition is a sacrifice of self and pursuit of idealism. Art exhibition is an internal exploration and social criticism. What both have in common is that they both give art educational and social significance. The difference is that the graduation exhibition is a formal, highly targeted exhibition of achievements that paves the way for future choices. The art exhibition is an open, crystallization of an art period, and a summary made by artists for themselves.

Published: September 2022

The U.S. continues to be a major player on the world stage. It is also a country whose religion continues to play a role in both politics and society. Because of this, it is important to understand the trends and changes going on with American religion in order to better understand the changes a major world player is experiencing. After the Immigration and Nationality Act of 1965, the number and categories of immigrants changed enormously. Based on the data of immigrants, I analyzed their nationality and numbers and found that Christianity believers decreased, the religiously unaffiliated people increased and the new religions’ believers, Islam, Hinduism etc., continually increased. I also found that the number and the characteristics of Christianity changed simultaneously in US. Finally, I used the generation change in American itself to explain why the number of religiously unaffiliated people increased so quickly.

Published: September 2022

This meta-analysis assessed the efficacy and safety of iclaprim compared with those of vancomycin in the treatment of acute bacterial skin and skin structure infection (ABSSSI). Only randomized controlled trials (RCTs) comparing the effect of iclaprim with vancomycin on adult patients with ABSSSIs were included. A total of 3 RCTs involving 1260 adult patients with ABSSSIs were enrolled. Iclaprim had a non-inferior clinical response rate compared with vancomycin. Similar trend was observed in the following subgroups: major cutaneous abscesses, cellulitis/erysipelas, wound infections, MRSA, MSSA, Streptococcus pyogenes infections. Finally, no differences were observed between iclaprim and vancomycin regarding the risks of any AE, drug-related AE, severe AE, discontinuation of study drug due to AE, and mortality. In conclusion, iclaprim exhibits non-inferior efficacy compared with vancomycin in the treatment of ABSSSI. Additionally, iclaprim was generally as well tolerated as vancomycin.

Published: September 2022

BACKGROUND:The heterogeneity of ejaculate indicates that fertility is still variable among bulls and that more stringent evaluation methods are needed to identify the ejaculates suitable for AI.OBJECTIVE:To identify and characterize the sperm subpopulations (SP) in thawed semen doses of Nelore and Angus bulls and to evaluate the influence of these sperm subpopulations on pregnancy rate in cows submitted to fixed-time AI (FTAI).MATERIALS AND METHODS:A dose of postthawed semen from each bull (n=18; consisting of Angusn= 9 and Neloren= 9) was analyzed for: sperm kinetics; morphology and plasma membrane integrity; and the determination of the sperm subpopulations. Differences between the groups were estimated with the t-test considering a significance level of <5%.RESULTS:There was no influence between breeding bulls for sperm morphology, plasma membrane integrity, and pregnancy rate (P> 0.05). Regarding the kinetic parameters evaluated by the CASA system, Nelore had greater values, for cells with slow velocity (Angus: 16.4 %; Nelore: 21.74%;P= 0.028). In contrast, ANGUS bulls had more static cells (Angus: 27.2%; Nelore: 9.3%;P= 0.048). Based on CASA system data and clustering procedures, four sperm subpopulations were statistically established. In Angus bulls, a higher level of fast and nonlinear spermatozoa were found in SP3 (33.3%), followed by SP1 (32.7%) with fast and progressive spermatozoa. Whereas, SP1 of Nelore bulls had 33.8% fast and progressive spermatozoa, followed by 32.2% of SP3 with fast and nonlinear spermatozoa.CONCLUSION:Both breeds of bulls presented similar proportions of sperm SP. Consequently, no influence on the pregnancy rates was shown in cows submitted to the IATF programs on a large scale.

BACKGROUND: Dissolved oxygen (DO) in semen dilutor may lead to the production of reactive oxygen species (ROS) and buffalo sperm may become more prone to deleterious effects of ROS due to the presence of high amounts of polyunsaturated fatty acids (PUFAs) in their membranes.
OBJECTIVE: To study the correlation between dissolved oxygen level, antioxidants and oxidants in semen diluted with partially deoxygenated extender at various stages of cryopreservation. MATERIALS AND METHODS: Each semen sample was split into two aliquots viz., Aliquot I
[diluted with Extender I (control: without deoxygenation)] and Aliquot II [diluted with Extender II: partially deoxygenated by liquid nitrogen (LN) flushing], which were diluted, filled in straws, cryopreserved and evaluated post-thaw. RESULTS: The DO levels ( P < 0.05) decreased
significantly after LN flushing of the extender and they increased significantly ( P < 0.05) in post-thaw semen. The progressive motility, viability, hypo-osmotic swelling response, acrosomal integrity, glutathione peroxidase (GPx), total antioxidant capacity (TAC) and superoxide
dismutase (SOD) decreased significantly ( P < 0.05) in both control and treated semen after thawing. SOD and TAC were positively correlated in semen treated with normal extender at the pre-freeze stage; however, in semen treated with partially deoxygenated extender, no correlation
was found between SOD and TAC at the pre-freeze stage. ROS and total TAC were negatively correlated in semen treated with partially deoxygenated extender at the pre-freeze stage; however, no correlation was found between ROS and TAC in control semen. CONCLUSION: The partial deoxygenation
of extender affects the correlation between sperm quality parameters, antioxidants, and oxidants during different stages of semen cryopreservation.

Applicability of limitative water-free production rate as case of field “B”
Authors: Sarybayev M. A. , Kurbanova A. R.
Published: September 2022

Developing a field underlayed by bottom water still remains one of the main issues in petroleum industry. Numerous articles have been devoted to this issue offering methods for calculating the maximum water-free production rate on such fields. The paper shows such production rate calculated for the field B. In this paper we also calculated maximum waterfree production rate with different initial reservoir parameters and identified the dependence of the maximum water-free production rate from formation exposure, permeability and viscosity. Based on these dependences we selected criteria that allow potential application of maximum water-free production rate.

Features of the structural and tectonic development of the Alakol region in connection with the prospect of its oil and gas potential
Authors: Sanatbekov M. E.
Published: September 2022

The article provides a brief analysis of the tectonic structure of the Alakol depression, which suggests a thrust overlap of oil and gas source strata in the ancient Alakol depression by the modern mountain system and expands the promising area for oil and gas exploration. The tectonic structure of the Alakol depression is characterized based on the Paleozoic surface map compiled from seismic data. Due to the poor knowledge of the oil and gas potential of sedimentary complexes of the Alakol depression, one can judge with some degree of conditionality about the prospects of their oil and gas potential. The high intensity of the tectonic regime that affected the structural and formation complexes is associated with horsts and grabens, which affected the lithological and paleogeographic conditions of rock formation.

Therefore, the scale of their oil potential is different and is determined by the type and concentration of organic matter. The scale of sea penetration and the existing lake-bog conditions of rock formation influencing the accumulated strata of the geological section with humic organic matter testifies to their prospects of oil and gas potential.

Authors: Pivovarov K. N. , Streletskaya V. V. , Zolotukhin A. B.
Published: September 2022

The article describes a unified approach to the assessment of resources and business planning. As an example, the paper considers oil and gas resources of the Pechora Sea. Based on the specifics of the problem (the quantity and quality of the available data and their nature), the methods of multicriteria fuzzy clusterization are used. The assessment of the prospects for the development of oil and gas fields was carried out using 3 criteria, namely: availability of resources (natural and climatic conditions of the region); hydrocarbon resources and their degree of exploration; economic assessment of the development. The results of such an analysis are presented in the form of maps of the Pechora Sea area, illustrating the most important and accessible areas and the sequence of their development. Such a stepwise development based on minimizing the risk and maximizing the benefits can be the basis for the successful and troublefree development of the resources of the entire region.

Authors: Edwards W.N.
Published: September 2022

Stem impressions of Lycopodiopsis (here taken to include Cyclodendron) are figured from the Permian of Western Australia, and the distribution of the genus is discussed. The stem impressions from the Permian of South Africa and Brazil hitherto recorded as "Sigillaria brardi" are considered to be older stems of Lycopodiopsis pedroanus. There are no satisfactory records of northern hemisphere lepidophytes in the Glossopteris flora of the southern hemisphere.
Fossil plants from the K'uanshanch'ang coal series of North-Eastern Yunnan, China
Authors: Hsu Jen
Published: September 2022

A collection of 34 species of plants from K'uangshanch'ang of the K'uangshanch'ang Coal Series of Huiche (formerly Tungchuan) district, north-eastern Yunnan, China, has been studied. It is a flora represented by Equisetales, Sphenophyllales, Pteridospermae (or Filicales), Cordaitales, and other groups. The majority of the fossils are fronds of Sphenopteris and Pecopteris and a large number of seeds.

Nine species are identical with or closely comparable to those from the Lower Shillhotze Series of central Shansi (which, according to Professor Halle, is of early Permian age); five are identical with or closely comparable to those from the Upper Shihhotze Series of the same province; seven are related to the Late Carboniferous flora of Sumatra; and four either identical or related to the Permian flora of Korea. This shows that the plants most probably belong to the earliest Permian age.

Five species are described as new: Pecopteris huichensis, P. Sahnii, P. yunnanensis, Tobleria minor and Cornucarpus huichensis.

The last-named species has a seed in organic connection with a sphenopteroid pinnule. Both geographically and in its palaeobotanical composition the Yunnan flora serves as a link between the Gigantopteris flora of China and Korea on the one side and that of Sumatra on the other. It suggests that the geological age of the K'uangshanch'ang Coal Series is earliest Permian.The specimens do not contain even a single species in common with the Indian Gondwana flora, a fact suggesting that there was no land bridge between Cathaysia and Gondwanaland in the early Permian age.
Spiroxylon Indicum sp. nov., a Taxinean wood from the Lower Gondwanas of India
Authors: Mehta K.R.
Published: September 2022

Spiroxylon indicum is the first record of Taxinean wood from the Lower Gondwanas of India and establishes the existence of plants showing Taxoidean anatomy in the Lower Permian strata. It is described from small fragments obtained from some carbonaceous shales and is characterized by the presence of Taxinean spirals in addition to the bordered pits on the walls of its tracheides. It is closely allied to Spiroxylon africanum described by Walton (1925) from South Africa, but differs from that species in certain important details. It is, therefore, described here as a new species. The structure of Spiroxylon indicum lends support to the view that the Taxads may possibly have originated from some Cordaitean ancestors.

The notes and photographs given here were left uncompleted by Professor Sahni. He believed that they were of great potential importance and had consulted many people about them during his tour of America and Europe. At the same time, he appears to have doubted the plant nature of some of the specimens. He left the photographs given here. together with some others. and a general introduction to the paper in note form. This I have freely edited and take responsibility for any mistakes that may have been made.

He left no full description of the specimens, but merely pencil notes written around some of the figures. In describing the specimens, I have availed myself of these notes but again I must assume responsibility for any mistakes.
