Research progress on wireless sensor network (WSN) security technology

Wireless sensor network (WSN) has been a frontier technology field that integrates a variety of technologies and has a wide range of applications in the military. Network security is of great significance in military warfare. First, this paper outlines the technical advantages of the application of military based on the technical characteristics of WSN. In military applications, WSN has been used in modern military combat while WSN features easy and fast deployment, high concealment, good fault tolerance, high accuracy and other obvious advantages. Moreover, from the perspective of network security, this paper reviews the research progress of network security technology at the network level and data level. The network level includes security protocols, key management, and secure routing technology, and key management includes pre-shared key mode and random key pre-distribution mode. At the data level, error control and fault-tolerant algorithms are mainly included. Automatic retransmission and forward error correction techniques are traditional error control methods, which should be combined with the specific situation of WSN to propose the corresponding fault-tolerant mechanism. Finally, this paper summarizes the practical applications of WSN in the military. From battlefield reconnaissance and target localization monitoring to destruction effect control and anti-terrorism equipment research, network security has been a top priority. Against the background of practical military applications, this paper summarizes the research significance of network security technology.
Work costs and operating regimes for different manners of system-reservoir interactions via collision model

In this work, we study effects of different types of system-reservoir interactions on work costs and operating regimes of thermal machines by considering a quantum system consisting of two subsystems embedded in both independent and common reservoirs. The model allows us to make a contrast between three configurations of system-reservoir interactions, namely, the three-body one, the two-body one with and without intrasystem interaction between two subsystems. After establishing general formulations of thermodynamics quantities, we derive specific forms of heat and work with respect to these three configurations based on a model with two coupled qubits. It is shown that both the amount and sign of work are closely related to ways of system-reservoir interactions, by which six types of operating regimes of machines are constructed for a given setting. We find that different modes of system-reservoir interactions lead to different numbers of operating regimes of machines on the one hand, and on the other hand machines of the same kinds can appear in different scenarios of system-reservoir interactions, but which one is superior over others relies on intervals of parameters. A possible implementation of the setup based on the platform of circuit quantum electrodynamics is discussed briefly. We then generalize the bipartite model to multipartite case and derive the corresponding formulations of thermodynamics quantities. Our results indicate that interacting manners of system-reservoir play an important role in modifying thermodynamics process and can thus be utilized in designing quantum thermal machines with requisite functions.
Investigations on the Requirements of Distributed Engineering Group Work

The aim of this thesis is to examine the use of the groupware system cAR/PE! , which is based on Mixed Reality technology. cAR/PE! was developed at the DaimlerChrylser Research Center in Ulm dedicated to distributed engineering group work and subsequently tested in two studies at various plants of DaimlerChrysler AG. Interviews and observations of engineer meetings in distributed project groups provided the basis for the conception of the two empirical studies. In the first study the first cAR/PE! prototype was tested. The study confirmed that less complex tasks could be solved equally well in both a conventional meeting room and in cAR/PE! meetings. However, when solving a complex task, the conventional meeting was more favorable than cAR/PE! These results were exploited for further developments of cAR/PE! resulting in cAR/PE! 2. In the second study, the modifications were evaluated under two conditions to solve the complex design task amphibious car. Under the first condition, groups were still better at solving a complex task under the conventional meeting2 condition compared with cAR/PE! 2, even the problem-solving processes were comparable and no longer structurally different than in the first study. The differences in the group results were caused by the software when using cAR/PE! 2. Under the second condition, the influence of the meeting workspace was tested; this had a direct influence on the problem-solving processes of the groups, but the result was not significant. However, from this outcome it was deduced that only the relevant information for the tasks and the physical placement of the speaker leads to a successful conversation. On the theoretical level, the enhancement of the framework developed by Vertegaal et al. (1997) introducing the concept of task awareness and the appropriateness of the Model for the elements of distributed group work were confirmed. On the practical level, cAR/PE! 2 was improved based on the results of both studies, then implemented and established as a permanent running groupware system between DaimlerChrysler’s plants in Sindelfingen and Bremen.
A high‐isolation linear folded mixer for ISM band in UMC 180NM CMOS technology

This paper presents an integrated radio frequency (RF) downconversion folded mixer that operates in the 2.4 GHz industrial, scientific, and medical (ISM) band by using UMC 180 nm RF CMOS. It is implemented by using a double‐balanced transconductance switch (GmSw) configuration. The proposed mixer converts the incoming signal to a small signal RF current followed by a PMOS current mirror structure. The circuit can operate with a power supply of less than 1.8 V. A superior isolation is achieved by incorporating a novel folded structure with a CMOS local oscillator (LO) stage. The proposed folded mixer achieves 7 dB of conversion gain and 8.5 dBm of the third order input intermodulation product. The highest measured isolation between the LO‐IF, RF‐IF, and LO‐RF ports is 50, 45, and 65 dB, respectively. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2461–2466, 2016

A Methodology for Translating Detonation Wave Effects between One and Two Dimensions

SUSI, BRYAN. A Methodology for Translating Detonation Wave Effects between One and Two Dimensions. (Under the direction of Dr. Kevin Lyons.) This research focuses on evaluating empirical methods and implementing a prototype Transitional Airblast Model (TRAM) for facilitating communication between onedimensional and two-dimensional airblast models. An overview of detonation phenomena is presented, especially concerning detonation waves and accompanying airblast effects. Two existing airblast models are discussed that were designed to predict the effects of a detonation in two separate types of geometries, one-dimensional and two-dimensional. The functionality and behavior of each airblast model will be scrutinized giving particular insight into their performance in applications with both one-dimensional and two-dimensional components. The strengths and deficiencies of the different airblast models will offer motivation for the development of the TRAM prototype. The TRAM prototype consists of two separate methodologies, one for translating one-dimensional airblast propagation to two dimensions, and another for translating two-dimensional airblast propagation to one dimension. The selection of those two methodologies will be presented, along with results of detonation scenarios using both existing airblast models as well as the TRAM prototype. The TRAM prototype performed well for both types of detonation scenarios and is recommended for further development.

Parameterized Vietoris-Rips Filtrations via Covers

A challenge in computational topology is to deal with large filtered geometric complexes built from point cloud data such as Vietoris-Rips filtrations. This has led to the development of schemes for parallel computation and compression which restrict simplices to lie in open sets in a cover of the data. We extend the method of acyclic carriers to the setting of persistent homology to give detailed bounds on the relationship between Vietoris-Rips filtrations restricted to covers and the full construction. We show how these complexes can be used to study data over a base space and use our results to guide the selection of covers of data. We demonstrate these techniques on a variety of covers, and show the utility of this construction in investigating higher-order homology of a model of high-dimensional image patches.
Regretful pleasure: Toward an understanding of flow cost in media use

Flow (state of intense focus) during media use has been largely considered a desirable experience, with technologies developed to maximize the chance of encountering flow in computer-mediated environments. However, the total absorption of attention due to flow could be problematic in contexts where the user has multiple predetermined goals, and engaging with the flow-inducing media could cost them resources that may be otherwise devoted to other goals. When flow imposes a cost on the user’s goal performance, it may also reduce their post-experience gratification with the flow-inducing media. The present study proposes a novel theoretical framework to begin understanding the potential cost of flow in media use with supporting evidence from two survey and vignette studies (N = 235 and N = 245). Its findings will extend human-computer interaction research by highlighting the double-edged impact that flow might have on media users’ larger goal performance and downstream well-being.
Disability, physical activity, and health-related quality of life in Australian adults: An investigation using 19 waves of a longitudinal cohort

Background Any form of long-term physical or mental impairment might negatively influence health-related quality of life (HRQoL). HRQoL, as an independent concept, covers a wide range of characteristics that includes physical, mental, social, and spiritual functions. People with disabilities are continuously exposed to multiple barriers that deteriorate their HRQoL. It also creates impairment in performing physical activities. However, experts opine regular physical exercise as an intervention to help disabled people. This research aims to investigate the association between disability and physical activity with HRQoL among the adult population in Australia. Design A retrospective cohort study. Methods This study utilized the most recent 19 waves of data (2002–2020) from the nationally representative Household, Income and Labour Dynamics in Australia (HILDA) survey. Component summary scores such as physical component summary (PCS) and mental component summary (MCS), and SF-6D utility scores were utilized to measure HRQoL. Random-effects GLS regression technique was fitted to estimate the association between disability and physical activity with HRQoL, after adjusting for a range of socio-demographic and health-related characteristics. Results Disability was negatively associated with the PCS (-5.95), MCS (-2.70) and SF-6D (-0.060) compared with non-disabled counterparts. However, respondents engaged in the recommended level of physical activity had substantial gain in PCS (b = 0.96), MCS (1.57), and SF-6D (0.021) scores. Besides, the results showed that performing the recommended level of physical activity in the presence of disability has lessen the negative effect of disability/ positive moderating effect of physical activity on PCS, MCS, and SF-6D scores by 1.84 points, 0.82 points, and 0.013 percentage points, respectively. Conclusion This study found an inverse association between disability and HRQoL among Australian adults. However, physical activity was associated with improved HRQoL. Therefore, public health interventions, such as the orientation of physical activities, have a higher potential to dwindle the burden regarding HRQoL.
Dynamic physical examination indicators of cardiovascular health: A single-center study in Shanghai, China

Dynamic physical examination data can provide both cross-sectional and time-series characteristics of cardiovascular health. However, most physical examination databases containing health and disease information have not been fully utilized in China. Hence, this study aimed to analyze dynamic physical examination indicators for cardiovascular health to provide evidence for precise prevention and control of cardiovascular diseases in the primary prevention domain among healthy population with different demographic characteristics in Shanghai. Three-year continuous data were collected from the physical examination center of a hospital in Shanghai from 2018 to 2020, which included a total of 14,044 participants with an average age of 46.51±15.57 years. The cardiovascular status of overall healthy individuals may have a decreasing trend, which is manifested as a significant year-on-year decrease in high-density lipoprotein cholesterol; a significant year-on-year increase in total cholesterol, low-density lipoprotein cholesterol, and blood glucose levels; and a possible increasing trend of diastolic blood pressure, body mass index, and triglycerides. Healthy population with different sex and age groups have various sensitives to cardiovascular physical examination indicators. To conduct more accurate cardiovascular health management and health promotion for key populations in primary prevention, focusing on the dynamic trends of blood pressure, blood lipids, blood glucose, and body mass index in men and changes in total cholesterol in women over time is especially important. The age group of 50–69 years is key for better prevention and control of cardiovascular health.
Overview of Existing Routing Protocols for Low Power and Lossy Networks

Low-power wireless devices, such as sensors, actuators and smart objects, present difficult constraints: very limited memory, little processing power, and long sleep periods. As most of these devices are battery-powered, energy efficiency is critically important. Wireless link qualities can vary significantly over time, requiring protocols to make agile decisions yet minimize topology change energy costs. Routing over such low power and lossy networks introduces requirements that existing routing protocols may not fully address. Using existing application requirements documents, this document derives a minimal and not exhaustive set of criteria for routing in low-power and lossy networks. It provides a brief survey of the strengths and weaknesses of existing protocols with respect to these criteria. From this survey it examines whether existing and mature IETF protocols can be used without modification in these networks, or whether further work is necessary. It concludes that no existing IETF protocol meets the requirements of this domain.
Organophosphate and Carbamate Residual Levels in Vegetables of Trang Municipality

This experimental research design aimed to study residual levels of organophosphate and carbamate in 360 samples of a vegetable widely consumed in Trang Municipality, located in southern province of Thailand. Three kinds of vegetables were most eaten vegetables, organic vegetables and locally grown vegetables. 190 samples of the most eaten vegetables included cilantro, kale, Chinese cabbage, cabbage, cauliflower, chili, spring onion, celery, yard long bean, cucumber, tomato, lettuce, egg plant, Thai egg plant, Chinese morning glory, white radish, devil? s fig, asparagus, lemon. 50 samples of the organic vegetables included Chinese morning glory, Chinese cabbage, kale, cabbage and yard long bean. 120 samples of the locally grown vegetables included morning glory, curry leaf, Liang vegetable, star gooseberry, Thai basil, chili, Gotu kola, bird lettuce, bitter bean, fresh pod color (red yard long bean). The most eaten vegetables were collected from 3 wholesale markets and 200 grams for each vegetable was randomly collected from 3 areas (top, bottom and middle). The organic and locally grown vegetables were collected from 3 retail sale markets and 200 gram for each vegetable was randomly collected from 3 areas (top, bottom and middle). The residual level of organophosphate and carbamate was examined with GPO-M kit of Medical Science Department, Ministry of Public Health. The samples were collected during April ? July 2015.The results revealed that unsafe level (cholinesterase inhibitor level of 50-70%) of organophosphate and carbamate were found in most eat eaten vegetables 79 samples (41.58%) from 190 samples. Kinds of vegetables found pesticide residuals included cilantro, kale, Chinese cabbage, cabbage, cauliflower, chili, celery, spring onion, yard long bean, cucumber, tomato, Thai egg plant, white radish and lemon. All organic and locally grown vegetables were found safe residual level of organophosphate and carbamate. Based on the results of this study, public health authorities should encourage consumer to eat organic or locally grown vegetables and should properly wash vegetable before cooking. In addition, gardeners should be aware of the dangers of chemical pesticides for good quality and food safety of Thai vegetables. Meanwhile, authorities should work proactively to advise the use of chemical pesticides correctly and monitored continuously among gardeners throughout the country.
Enrichment of TP53 alterations within GCB-like DNA subclassifications of diffuse large B-cell lymphoma after transition from de-novo to relapsed or refractory disease

quent expression of CD20 and a less-frequent expression of CD56 [4, 5]. Several myeloma studies have shown that CD20 expression is associated with small-cell-type neoplastic PCs and t(11;14) in PCM [6, 7]. As CD56 is an adhesion molecule, PCs with no CD56 expression may reduce cell-to-cell interactions, easily escape from the bone marrow, invade extramedullary organs, including the peripheral blood, and proliferate abnormally beyond immune surveillance [4, 5]. To date, only 5 cases of small-cell-type PCL (Table 1) have been reported, while clonal PCs of the small-cell-type are found only in 3.4% of PCM [7-10]. The median age of the 6 cases including ours was 70.2 years with no demographic preponderance. The 6 cases of small-cell-type PCL demonstrated a variable expression of CD20 and loss of CD56. t(11;14) (IGH/CCND1 rearrangement), and overexpression of CCND1 or CCND2 was detected in 5 cases. Their secreting components were IgG or IgA with lambda or kappa light chains, including only one kappa light chain. The amount of M protein was not associated with the tumor burden. Two patients died within a year of starting chemotherapy. In summary, we report a rare case of pPCL with t(11;14) presenting as the small-cell type. When diagnosing PCL of an atypical plasma cell type, it is mandatory to use FCM immunophenotyping for the bone marrow and peripheral blood specimens with morphology and IFE.
Impact of Tween 80 on Fatty Acid Composition in Two Bacterial Species.

Tween 80 is a well-known non-ionic emulsifier which is used in pharmaceutical and food industries. Due to its widespread applications it is needed to understand how it affects bacteria. The current study aimed to investigate the effect of Tween 80 on the fatty acid content of bacteria. Three bacterial isolates were used in this study: two isolates of Serratia marcescens and one isolate of Acinetobacter baumannii. The analysis of fatty acid components of bacterial lipids was performed, followed by the assessment of the effect of Tween 80 on fatty acid content by adding it to the culture medium in three concentrations: 0.1%, 0.5% , and 1.0 % . The results indicated that the Tween 80 has the ability to change the fatty acid content present in these bacteria by the appearance and disappearance of three fatty acids, including Elaidic acid 18.1 trance 9, Oleic acid 18.1 cis 9, and erucic acid 22.1, which belong to Mono-Unsaturated Fatty Acids (MUFA), in the presence of different concentrations of Tween 80. The results also demonstrated that the p-value was significant in two situations, the first belonged to S. marcescens at 0.5 % concentration for all groups of FAs (Saturated fatty acids, Monounsaturated fatty acids, and polyunsaturated fatty acids), and the second was for S. marcescens just in MUFA in all concentrations of Tween 80.
Probiotics as an adjuvant for management of gastrointestinal cancers through their anti-inflammatory effects: a mechanistic review.

The immune system's role in maintaining the health of the gastrointestinal (GI) system is like a double-edged sword. Simultaneously, it could reduce the risk of pathogen invasion by the inflammatory response. But, if regulated improperly, it could also propagate oncogenic signaling that transfers a normal cell into the malignant counterpart. Thus far, several mechanisms have been proposed, such as the immune system could disturb the GI homeostasis and increase the survival and proliferative capacity of cells leading to the formation of a wide range of malignancies. Among the endless list of these mechanisms, inflammatory responses are currently fascinating research areas, as this response regulation is with the gut microbiota. Given this, the manipulation of microbiota might be a convenient and efficient way to prevent GI cancers. Probiotics could potentially achieve this by overturning the milieu in favor of normal gut homeostasis. In addition to the safety of use of probiotics, along with their potential ability to interact with immune system responses, led these bacteria to be viewed differently from dietary supplements. In the present review, we aimed to look into the mechanisms through which probiotics modulate the immune responses to stimulate anti-inflammatory responses and promote immune surveillance against neoplastic cells.
