Logic Controller-Based Discontinuous Reception (DRX) System for NR

In Long Term Evolution (LTE) system, discontinuous reception (DRX) mechanism is widely used as a reliable and effective means of reducing energy consumption. Moving to 5G New Radio, the application scenarios of massive Machine Type of Communication (mMTC) have become increasingly clear, which will support ultra-large-scale device accessing into the network. Therefore, the need for energy efficiency improvement of terminal equipment is becoming more and more urgent under 5G NR. In this paper, a logic controller-based DRX system was proposed to make original DRX more efficient. With logic controller, DRX parameters can be adaptively adjusted by learning the information of historical delay time and packets arrival rate. And then, a better performance of energy conservation will be achieved. Simulation results show the performance improvement of the proposed DRX system.

Dynamic Perception Framework for Fine-Grained Recognition

Fine-grained recognition poses the challenge of discriminating categories with only small subtle visual differences, which can be easily overwhelmed by diverse appearance within categories. Conventional approaches generally locate discriminative parts and then recognize the part-based features. However, we find that tuning the effective receptive field (ERF) of the network to the task plays the key role, which enables significant regions to contribute more to the output. Inspired by the receptive field stimulation mechanism of the visual cortex, we propose a Dynamic Perception framework as a solution. Our framework adapts the ERF by considering the image space and the kernel space simultaneously. In the image space, the Spatial Selective Sampling module is adopted to enlarge informative regions locally. In the kernel space, Spatial Selective Kernel convolution is introduced to adapt different kernel sizes for regions of interest and backgrounds by embedding spatial attention in the multi-path convolution. Extensive experiments on challenging benchmarks, including CUB-200-2011, FGVC-Aircraft, and Stanford Cars, demonstrate that our method yields a performance boost over the state-of-the-art methods.

From the barbecue to the sauna: A comparative account of the folding of media reception into the everyday life

How and why do people still get print newspapers in an era dominated by mobile and social media communication? In this article, we answer this question about the permanence of traditional media in a digital media ecosystem by analyzing 488 semi-structured interviews conducted in Argentina, Finland, Israel, Japan, and the United States. We focus on three mechanisms of media reception: access, sociality, and ritualization. Our findings show that these mechanisms are decisively shaped by patterns of everyday life that are not captured by the scholarly foci on either content- or technology-influences on media use. Thus, we argue that a non-media centric approach improves descriptive fit and adds heuristic power by bringing a wider lens into crucial mechanisms of media reception in ways that expand the conceptual toolkit that scholars can utilize to analyze the role of media in everyday life.

Transcriptome Characterization and Expression Analysis of Chemosensory Genes in Chilo sacchariphagus (Lepidoptera Crambidae), a Key Pest of Sugarcane.

Insect chemoreception involves many families of genes, including odourant/pheromone binding proteins (OBP/PBPs), chemosensory proteins (CSPs), odourant receptors (ORs), ionotropic receptors (IRs), and sensory neuron membrane proteins (SNMPs), which play irreplaceable roles in mediating insect behaviors such as host location, foraging, mating, oviposition, and avoidance of danger. However, little is known about the molecular mechanism of olfactory reception in Chilo sacchariphagus, which is a major pest of sugarcane. A set of 72 candidate chemosensory genes, including 31 OBPs/PBPs, 15 CSPs, 11 ORs, 13 IRs, and two SNMPs, were identified in four transcriptomes from different tissues and genders of C. sacchariphagus. Phylogenetic analysis was conducted on gene families and paralogs from other model insect species. Quantitative real-time PCR (qRT-PCR) showed that most of these chemosensory genes exhibited antennae-biased expression, but some had high expression in bodies. Most of the identified chemosensory genes were likely involved in chemoreception. This study provides a molecular foundation for the function of chemosensory proteins, and an opportunity for understanding how C. sacchariphagus behaviors are mediated via chemical cues. This research might facilitate the discovery of novel strategies for pest management in agricultural ecosystems.

Effects of Hydrosalpinx on Endometrial Implantation Failures: Evaluating Salpingectomy in Women Undergoing in vitro fertilization.

Hydrosalpinx is a disease characterized by the obstruction of the salpinx, with progressive accumulation in the shape of a fluid-filled sac at the distal part of the tuba uterina, and closed to the ovary. Women with hydrosalpinges have lower implantation and pregnancy rates due to a combination of mechanical and chemical factors thought to disrupt the endometrial environment. Evidence suggests that the presence of hydrosalpinx reduces the rate of pregnancy with assisted reproductive technology. The main aim of the present is review to make an overview of the possible effects of hydrosalpinx on in vitro fertilization (IVF). We conducted a literature search on the PubMed, Ovid MEDLINE, and Google Scholar data bases regarding hydrosalpinx and IVF outcomes. Hydrosalpinx probably has a direct toxic effect on sperm motility and on the embryos. In addition, the increasing liquid inside the salpinges could alter the mechanisms of endometrial receptivity. The window of endometrial receptivity is essential in the implantation of blastocysts, and it triggers multiple reactions arising from the endometrium as well as the blastocysts. Hydrosalpinx could influence the expression of homeobox A10 (HOXA10) gene, which plays an essential role in directing embryonic development and implantation. Salpingectomy restores the endometrial expression of HOXA10; therefore, it may be one mechanism by which tubal removal could result in improved implantation rates in IVF. In addition, salpingectomy does not affect the ovarian response, nor reduces the antral follicle count. Further studies are needed to establish the therapeutic value of fluid aspiration under ultrasonographic guidance, during or after oocyte retrieval, in terms of pregnancy rate and ongoing pregnancy.

A New Design and Analysis of Power Saving for IoT Gateway

Internet of Things (IoT) enables the connection of physical objects to the internet for exchanging information. Due to the massive number of IoT devices, cellular traffic is increasing exponentially in wireless networks. IoT devices require low latency, high reliability and massive connectivity. Fifth Generation (5G) networks are expected to provide promising solutions to meet these demands and improve the performance of IoT systems. 5G offers low latency, high reliability, and efficient data transmissions for large number of connected IoT devices. IoT systems employ gateways for efficient connectivity of various devices. Gateways have capabilities of integrating various protocols, handling data storage temporarily, analyzing the data, and transmitting that data between edge devices and cloud. IoT devices transmit data in frequent intervals, causing the gateway to be active all the time, leading to the increase in power consumption of the gateways. In this article, we focus on applying Discontinuous Reception (DRX) mechanism to IoT gateways. The proposed DRX at IoT gateways reduces the power consumption and improves the energy efficiency of IoT gateways. Our proposed work improves the energy efficiency of gateways by almost 30% compared to Relay Energy Efficiency (REE) based scheme.

Receptivity and transition in a solitary wave boundary layer over random bottom topography

Abstract

Hypersonic boundary layer receptivity on flat plate with blunt leading edge due to acoustic disturbance

In the process of hypersonic boundary layer transition, the leading edge receptivity due to free-stream acoustic disturbance provides unstable perturbations in boundary layer with initial amplitudes, which is one of hot issues in the study about transition mechanism. The receptivity of leading edge is influenced by many factors, involving geometry parameters, disturbance types, etc., among which the bluntness plays a key role for generating disturbances. In order to reveal the mechanism of bluntness influence on the boundary layer transition, investigations into the acoustic receptivity on flat plates with sharp and blunt leading edge are carried out. The flow conditions are as follows: Mach number 6, Reynolds number 1e7/m, adiabatic wall. By introducing two-dimensional plane fast and slow acoustic waves into the free-stream, the whole receptivity process of free-stream disturbances passing through shock wave into boundary layer is simulated with high-order accuracy DNS method. With sharp leading edge as a reference, the generation mechanism of the perturbations near blunt leading edge and its influence on the boundary layer downstream are analyzed. Some conclusions are obtained: for acoustic disturbances in hypersonic free-streams, the receptivity mechanism of blunt leading edge is different from that of sharp leading edge; both the fast and the slow mode can be produced respectively near the sharp leading edge by the fast and the slow acoustic wave, while only fast mode appears near the blunt leading edge; the receptivity of blunt leading edge due to the fast acoustic is stronger than that due to slow acoustic, and is also stronger than that of the sharp leading edge in a certain region of boundary layer downstream.

Epigenetic regulator Stuxnet modulates octopamine effect on sleep through a Stuxnet-Polycomb-Octβ2R cascade.

Sleep homeostasis is crucial for sleep regulation. The role of epigenetic regulation in sleep homeostasis is unestablished. Previous studies showed that octopamine is important for sleep homeostasis. However, the regulatory mechanism of octopamine reception in sleep is unknown. In this study, we identify an epigenetic regulatory cascade (Stuxnet-Polycomb-Octβ2R) that modulates the octopamine receptor in Drosophila. We demonstrate that stuxnet positively regulates Octβ2R through repression of Polycomb in the ellipsoid body of the adult fly brain and that Octβ2R is one of the major receptors mediating octopamine function in sleep homeostasis. In response to octopamine, Octβ2R transcription is inhibited as a result of stuxnet downregulation. This feedback through the Stuxnet-Polycomb-Octβ2R cascade is crucial for sleep homeostasis regulation. This study demonstrates a Stuxnet-Polycomb-Octβ2R-mediated epigenetic regulatory mechanism for octopamine reception, thus providing an example of epigenetic regulation of sleep homeostasis.

Thermal Performance Enhancement With DRX in 5G Millimeter Wave Communication System

The evolution of the communication and computation systems enables the user equipment (UE) to handle tremendous transmission data. However, the high-speed data processing also makes UEs release heat and might burn the chips inside the devices. The thermal issue would be more critical in millimeter-wave communications. The massive antenna arrays and the radio frequency modules not only drain the UE battery but also heat the devices. 3GPP also identified the thermal issue and suppressed heat generation by temporarily reducing UE capability in Release 15. In this work, instead of reducing the UE capability, we propose to apply the beam-aware Discontinuous Reception (DRX) mechanism to manage the power consumption and temperature of UEs simultaneously. We are the first to analyze the temperature for UEs with DRX configured. A semi-Markov model is provided, and we employ it to estimate the sleep ratio, packet delay, and steady temperature. We use a simulation program to verify the proposed analytical model. When comparing the beam-aware DRX with the baseline 5G NR DRX operation, we find that the beam-aware scheme reduces the steady temperature from $38.2^\circ C$ to $26.7^\circ C$ . The results show that Beam-Aware DRX could solve the thermal issue without sacrificing much performance of packet delivery latency.

Даниил Хармс в Китае

Daniil Kharms — a distinguished representative of the post-revolutionary avant- garde — was rediscovered in Russia in the 1990s. Chinese scholars began the study of his literary heritage in 2010 after a number of Kharms’ works had been translated into Chinese. Today, Kharms studies have become one of the most relevant trends within Chinese Slavic studies. This paper aims to examine Chinese interpretation of the core philosophical and aesthetic features of Kharms’ poetics in comparison with Russian scholarly interpretations and to analyze the mechanisms of reception of Kharms’s poetry and philosophy in China. Chinese scholars relate Kharms’ artistic techniques to the idea of the helplessness of a human being in the face of ontological problems. In general, Chinese scholars share an opinion that the originality of Kharms’ poetics meets the requirement of the new artistic style characterized by deconstruction of causality and the shift of the space-time continuum. The new state of art corresponds to the logic of human knowledge: within the process of renunciation (negating the negation itself), the new knowledge develops out of the opposite side of the old knowledge, which explains why the avant-garde is eternal.

Когнитивные аспекты восприятия жанров популярной литературы и их историческая изменчивость

In the article, the author investigates connections between historical variability of literary genres and readers’ ability to recognize them. Following J.-M. Schaeffer, the author understands genre as a semiotic sign constituted of a “generic name” and “generic notion.” The author interprets Schaeffer’s theory from the perspective of cognitive poetics and treats genres as “prototypes.” Their nature is both individual and collective—it derives from a person’s individual experience and skills of aesthetic reception, but also from social imaginary and stereotypes. The author focuses on a noncanonical genre of popular literature—science fiction—and argues that social and receptive aspects of the genre are interconnected. In the final part, the author analyses the image of “generation starship” in science fiction and concludes that changes of poetic techniques used to create fictional space of science-fictional starships—which has no correlation with readers’ empirical surroundings—formed a new “reading paradigm”, i.e., addressed mechanisms of reception that were not relevant previously in the history of the genre.

The Image of The Second World War as a Factor in the Formation of Contemporary European Identity

The image of the Second world war is one of the most significant images of the past for the European identity. The purpose of this study is to analyze its potential for the formation of the modern European identity as a supranational construct. The results of the study showed the ambivalent nature of this potential. On the one hand, the image of the Second world war retains a sufficiently powerful unifying impulse. It is determined by the uniting role of the colossal tragedy, the common misfortune that befell Europe in the middle of the past century, its integrational significance for the beginning of joint efforts to build a single European community in order to prevent the recurrence of these events. Today, this momentum is realized through the preservation of European memory, the institutionalization of anniversaries, the broadcast of the memory of the war in the process of intergenerational communication in the functioning of the institutions of education and cultural environment as a whole, the articulation of traumatic memories in the political discourse. On the other hand, the image of World War Two has a serious deconsolidating charge for the common European identity. It is caused by contradictions in the European collective memory, which are more and more clearly manifested in the conditions of modern political conjuncture. The new technological revolution that has engulfed Europe, accompanied by a steady shift of communication practices into cyberspace and the emergence of the phenomenon of cyber-memory, changes the mechanisms of representation and reception of the image of the Second World War. In the presence of the Global Network, we observe a steady increase of not only the arsenal of means for the representation and visualization of the image of the past, making it more interactive, multimodal, multifaceted and simplified, but also of the number of actors of memory politics, taking part in the formation of the European identity, or rather — an unlimited set of identities.

Joint use of DSRC and C‐V2X for V2X communications in the 5.9 GHz ITS band

Vehicular communications networks form the backbone of cooperative intelligent transport systems to support road safety and infotainment applications amongst users. IEEE 802.11p of the Dedicated Short-Range Communications protocol stack has been the technology of choice for Vehicle-to-Everything communications within the United States and Japan and has been extensively trailed in other countries such as Australia. With the advent of cellular technologies, a new, competing cellular-based Device-to-Device technology, known as Cellular Vehicle-to-Everything Sidelink, has emerged. Considering both technologies suffer from performance limitations, there is a current debate as to which of these technologies will eventually dominate the cooperative intelligent transport systems landscape if they cannot coexist. To investigate mechanisms of spectrum sharing between Dedicated Short-Range Communications and Cellular Vehicle-to-Everything for deployment in a common region, this paper initially reviews the background and technicalities of both technologies. The paper subsequently sets forth Vehicle-to-Everything platform models that allow not only spectrum sharing at the ITS band but also concurrent and simultaneous propagations of Dedicated Short-Range Communications and Cellular Vehicle-to-Everything messages. The transmission and reception mechanisms of hybrid Vehicle-to-Everything platforms are verified through a describing function model.

Cultural connotations of the image of perception of emigrants in Chinese ethnic consciousness of the 20-40s of the 20th century based on the material of Chinese literature and publicism

The relevance of the study is determined by the interest of modern humanitarian knowledge in the study of the image of the alien, the study of the mechanisms of reception of the foreign and other ethnic world in the process of interethnic and intercultural interaction of the 20th century. The novelty is due to the involvement of the material of journalistic and artistic texts of the Chinese authors of the left and right wing in their correlation with the historical, political and linguocultural realities of the 20-40s of the 20th century. The research problem consists in the correlation of ethnocultural, ethnopsychological and socio-political connotations of the image of the perception of an emigrant in the Chinese ethnic consciousness. The aim of the research is to study the lexical and semantic transformations of the concept of emigrant in the context of Chinese ideology and Chinese literature of the 20-40s of the 20th century, as well as to identify the individual features of the artistic perception of an emigrant by Chinese writers. The research methodology is based on an imagological approach to the study of literature with the involvement of ethnopsychological observations. The work uses historical-literary, comparative-historical, lexical-semantic methods, as well as techniques of translation studies. It is discovered that in the Chinese fiction and journalistic texts of the 20-40s of the 20th century the negative artistic image of the perception of emigrants - white emigrants prevails. Thus, in the Chinese ethnic consciousness of the 1920s and 1940s, the cultural connotation of the concept of emigrant had negative semantics. On the one hand, it reflects the real situation of emigrant life and emigrant consciousness; on the other hand, it captures the complex socio-political and ethno psychological processes that have taken place in Chinese society, affecting the foundation of Chinese culture and Chinese ethnicity.
