AI-empowered IoT Security for Smart Cities

Smart cities fully utilize the new generation of Internet of Things (IoT) technology in the process of urban informatization to optimize the urban management and service. However, in the IoT system, while information exchange and communication, wireless sensor network devices may not be able to resist all forms of attacks, which may lead to security issues such as user data disclosure. Aiming at the information security risks in smart city, the typical technologies in IoT is analyzed from the perspective of IoT perception layer and provides corresponding security solutions for the existing security threats. Regarding the communication security, the emerging wireless technology, long range (LoRa), is discussed, and the performance of wireless communication protocol is analyzed through simulation experiments, to verify that the IoT technology based on LoRa communication technology can improve the security of the system in the construction of smart city. The results show that REBEB, a new backoff algorithm, is similar to the binary exponential backoff algorithm in terms of throughput performance. REBEB focuses more on fairness, which is up to 0.985, and to a certain extent, its security is significantly improved. The fairness of REBEB algorithm is more than 0.4 in different nodes and competing windows, and the fairness of the system is better when the number of nodes is small. To sum up, the IoT system based on LoRa communication can effectively improve the security performance of the system in the construction of smart city and avoid the security threats in the IoT signal transmission.
Navel orange fine root nutrient content and rhizosphere effects varied with tree ages and soil depths in a hilly red soil region of China

ABSTRACT Root nutrients are required for the growth and development of roots and shoots, which are closely related to soil quality and fruit productivity. In this study, trees of contrasting stand ages, including young, middle-aged, and old trees, were selected in field sites with common management practices in the navel orange (Citrus sinensis) orchards of Southern China. The fine root N decreased with soil depth and the fine root P was higher of old trees (1.82 g kg-1) than young (1.57 g.kg-1) and middle-aged trees (1.37 g. kg-1). Soil organic C, total N, and P generally increased with plant age in the rhizosphere and bulk soils, while reverse trend was found for sucrase and urease activities. Interestingly, acid phosphatase activity was much higher at a lower depth (202 and 82 g.kg-1 OC d-1 for rhizosphere and bulk soils, respectively) than at an upper depth (46 and 43 g.kg-1 OC d-1 for rhizosphere and bulk soils, respectively). In conclusion, root and soil nutrients generally increased with plant growth. Fine root N decreased while fine root P remained unchanged with soil depth due to the content and rhizosphere effect of index at different soil layers related to N and P, respectively.
Optimizing the Spectral Efficiency in mmWave Massive SU-MIMO Systems Using Hybrid Processing

In this letter, a methodology to optimize the spectral efficiency in downlink massive single-user multiple-input multiple-output (SU-MIMO) millimeter-wave (mmWave) systems is proposed. Making use of a hierarchical strategy, four optimization sub-problems are formulated, whose solutions and derivations are strongly related to each other. This fact produces efficient coordination between the parties involved such that higher spectral efficiency is achieved. Therefore, the main feature of the proposed methodology relies on the coordination of the proposed RF and passband beamformer of both the transmitter and the receiver. This fact produced that the proposed hybrid processing surpasses the considered hybrid processings and even the considered fully-digital technique in the simulated scenarios.

Has Digital Financial Inclusion Narrowed the Urban-Rural Income Gap: The Role of Entrepreneurship in China

The combination of digital technology and finance has brought about a new development model for financial inclusion. What impact will it have on the current imbalance in the distribution of financial resources and the urban-rural income gap in China? To answer this question, this paper uses relevant data from 2014–2018 to study the impact of digital inclusive finance on the urban-rural income gap from the theory of financial exclusion, and analyzes the transmission of digital inclusive finance through alleviating financial exclusion, widening financing channels and helping residents with entrepreneurial spirit to start their own businesses, thus increasing jobs, raising the income of rural residents and reducing the urban-rural income gap. The conclusions are as follows: (1) digital inclusive finance can significantly converge the urban-rural income gap; (2) among the dimensions of digital inclusive finance, only the breadth of coverage can significantly reduce the urban-rural income gap, while the effects of depth of use and digitalization are not significant; (3) digital inclusive finance can alleviate the urban-rural income gap through the transmission mechanism of promoting residents’ entrepreneurship; (4) the worse the regional economic development and education, the better the effect of digital inclusive finance on the urban-rural income gap. This paper combines the above results to propose corresponding policy recommendations.
Psychometric properties of quantitative sensory testing focusing on healthy and patients with shoulder pain: a systematic review protocol

Background: Quantitative sensory testing (QST) is a battery of non-invasive psychophysical methods to assess the function of somatosensory system. Although the use of QST is widespread and several studies in patients with chronic shoulder pain have used it, the level of evidence for the psychometric properties has not been established. The aim of this protocol is to investigate, through a systematic review, the level of evidence for the psychometric properties of QST in the shoulder.Methods: For conducting and reporting this review the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines and the consensus-based standards for the selection of health measurement instruments (COSMIN) guidelines will be used. Nine databases including PubMed, Medline, AMED (via EBSCO), PEDRO, Embase, Web of Science, Scopus, SportDiscus, Google Scholar and Cochrane Library will be searched for the period from their inception until September 2021. Two reviewers (BP and SK) will independently evaluate the retrieved articles (titles and abstracts) and the psychometric characteristics checklist based on the standards from the COSMIN. The modified grading of recommendations assessment, development, and evaluation (GRADE) approach will be used to assess the overall quality of the evidence.Conclusions: Evaluation of the level of evidence for the psychometric properties of QST in the shoulder is an essential step for evidence-based assessment in clinical practice.Trial registration: PROSPERO registration number is CRD42021232778.
The role of science advice in recovery potential assessments in freshwater fish listing decisions under the Canadian Species at Risk Act

Fishes assessed as Threatened or Endangered by the Committee on the Status of Endangered Wildlife in Canada are disproportionately less likely to be listed under the federal Species at Risk Act (SARA) compared to other taxa. We examined the extent to which the amount and type of science advice in a Recovery Potential Assessment (RPA) contributes to SARA-listing decisions for 34 wildlife species of freshwater fishes in Canada. We used a generalized linear mixed model to describe SARA listing status as a function of RPA completeness. Principal coordinates analyses were conducted to assess similarity in answers to RPA questions among listed and nonlisted species. The amount and type of science advice within an RPA were weakly related to SARA status. RPA completeness accounted for only 7.4% of model variation when family was included as a random effect, likely because nine species not listed under SARA (64%) belong to the sturgeon family. Our results suggest that, while potentially useful for informing recovery strategies, RPAs do not appear to be driving listing status for freshwater fishes in Canada. Factors beyond scientific advice likely contribute to nonlisted species and delays in listing decisions.
BER analysis of truncated SVD‐based MU‐MIMO ZF detection scheme under correlated Rayleigh fading channel

In multi‐user multiple input multiple output (MU‐MIMO) uplink, the bit error rate (BER) of linear detection schemes, namely, zero forcing (ZF) and minimum mean square error (MMSE) under correlated Rayleigh fading channel deteriorates with increase in spatial correlation and load factor due to the increase in the condition number of the channel matrix. Moreover, the performance gap between ZF and MMSE increases with increase in the antenna number for large load factors. To address this issue, in this paper, truncated singular value decomposition (TSVD), which is a popular method for solving ill‐posed problem, is used in the ZF detection process through proper selection of hard threshold. However, the pseudo‐inverse computed using TSVD is an approximate inverse, which results in interference at the output of the detection process. Therefore, a mathematical expression for the post‐processing signal‐to‐interference‐plus‐noise ratio (SINR) of the substream is derived and subsequently BER is evaluated. Further, the analytical BER is analyzed with respect to the parameters namely, average signal‐to‐noise ratio (SNR) ( EsN0 ), correlation coefficient ( ρU,ρB ), load factor ( β ), and number of singular values considered to compute the hard threshold ( n ) and also validated by Monte Carlo trails. From the simulation results, it is observed that for higher order MU‐MIMO systems and at lower values of EsN0 , the performance of TSVD‐based scheme is comparable with that of MMSE by decreasing the truncation parameter ( k ). Moreover, as the complexity of TSVD‐based ZF using randomized schemes is O(NU2NB+NU2log(k)+NUk2 ), therefore, the complexity of detection significantly decreases with decrease in k .
TEI-DTA: Optimizing a Vehicular Sensor Network Operating with Ultra-Low Power System-on-Chips

In the era of the Internet of Things (IoT), the interest and demand for embedded systems have been explosively increasing. In particular, vehicular sensor networks are one of the fields where IoT-oriented embedded devices (also known as IoT devices) are being actively used. These IoT devices are widely deployed in and out of the vehicle to check vehicle conditions, prevent accidents, and support autonomous driving, forming a vehicular sensor network. In particular, such sensor networks mainly consist of third-party devices that operate independently of the vehicle and run on their own batteries. After all, like all battery-powered embedded devices, the IoT devices for the vehicular sensor network also suffer from limited power sources, and thus research on how to design/operate them energy-efficiently is drawing attention from both academia and industry. This paper notes that the vehicular sensor network may be the best application for ultra-low power system on-chips (ULP SoCs). The ULP SoCs are mainly designed based on ultra-low voltage operating (ULV) circuits, and this paper aims to realize the energy-optimized driving of the network by applying state of the art (SoA) low-power techniques exploiting the unique characteristics of ULV circuits to the IoT devices in the vehicular sensor network. To this end, this paper proposes an optimal task assignment algorithm that can achieve the best energy-efficient drive of the target network by fully utilizing the SoA low power techniques for ULV circuits. Along with a detailed description of the proposed algorithm, this paper demonstrates the effectiveness of the proposed method by providing an in-depth evaluation process and experimental results for the proposed algorithm.
Effect of Hemadsorption in Critically Ill Patients with COVID-19 (CYTOCOV-19): A Prospective Randomized Controlled Pilot Trial

Purpose: Immunomodulatory therapies have shown beneficial effects in patients with severe COVID-19. Patients with hypercytokinemia might benefit from removal of inflammatory mediators via hemadsorption.Methods: Single-center prospective randomized trial at the University Medical Center Hamburg-Eppendorf (Germany). Patients with confirmed COVID-19, refractory shock (norepinephrine ≥0.2 μg/kg/min to maintain a mean arterial pressure ≥ 65 mmHg), IL-6≥500 ng/l and an indication for renal replacement therapy (RRT) or extracorporeal membrane oxygenation (ECMO) were included. Patients received either hemadsorption therapy (HT) or standard medical therapy (SMT). For HT, a CytoSorb® adsorber was used for up to 5 days and was replaced every 18–24 hours. The primary endpoint was sustained hemodynamic improvement (norepinephrine ≤0.05 µg/kg/min≥24h). Secondary endpoints included 28-day mortality, SOFA, and reduction of IL-6, PCT, and MR-proADM. Results: Of 242 screened patients, 24 were randomized and assigned to either HT (N=12) or SMT (N=12). Both groups had similar severity as assessed by SAPS II (median 75 points HT group vs. 79 SMT group, p=0.590) and SOFA (17 vs. 16, p=0.551). At randomization, 22 (92%) patients were on RRT and 11 (46%) had vv-ECMO. Median IL-6 levels were 2269 (IQR 948–3679) and 3747 (1301–5415) ng/l in the HT and SMT group at baseline, respectively (p=0.378). Serum IL-6 reduction in the first 24h of treatment compared between both groups was 83% vs. 46% (p=0.235). Shock resolution (primary endpoint) was reached in 33% (4/12) vs. 17% (2/12) in the HT and SMT group, respectively (p=0.640). 28-day mortality was 58% (7/12) in the HT compared to 67% (8/12) in the SMT group (p=1.0). Conclusion: HT was associated with a non-significant trend towards clinical improvement within the intervention period including reduction of IL-6 levels and shock resolution. In selected patients, HT might therefore be an option for stabilization and bridge to transfer and decision.

‘Watson’ the Wellness Dog: Impact of a Wellness Dog on Emotional Wellbeing in Undergraduate Paramedicine Students

Introduction University life can be daunting, especially for those transferring directly from high school. Previous research has found higher education students are at increased risk of mental health issues than the general population. Paramedic students have the usual concerns regarding study, in addition to the potential to be exposed to confronting emergency medical situations during clinical placements. The study aim was to examine whether the presence of a wellness dog had any impact on paramedicine undergraduate students self-reported emotional wellbeing. Methods A wellness dog (named ‘Watson’) was available on alternating weeks for 15 minutes at the beginning of lectures for three individual units. Each unit corresponded to a different year group of paramedic undergraduate students. A brief emotional experience scale was completed at the beginning of each lecture. Comparisons were made between Watson being present versus absent to gauge differences in students’ emotional wellness. Focus groups were run at the end of semester to further explore perceptions of Watson's impact on emotional wellbeing. Results A total of 89 participants were included in the study. Participant emotional wellbeing was found to be higher on ‘Watson present’ weeks compared to ‘Watson absent’ weeks (p<0.001). Focus group data strongly supported Watson's presence in clinical and non-clinical classes, improving self-reported wellbeing and cohort connectivity. Conclusion The presence of a wellness dog appears to have a beneficial impact on undergraduate paramedic students’ emotional wellbeing. Further research is required to explore whether the presence of a wellness dog affects physiological indicators of stress, attrition rates and class attendance.
Habitat-Related Differences in Winter Presence and Spring–Summer Activity of Roe Deer in Warsaw

Preliminary research conducted in Warsaw in the 1970s and 2000s showed that roe deer (Capreolus capreolus) stayed in forest habitat and avoided anthropogenic areas. Activity and exploration patterns of animals are shaped by indices of anthropogenic disturbances, elevated in large cities. The aims of the study were (1) to compare the presence of roe deer in natural and anthropogenic habitats of Warsaw during three periods: 1976–1978, 2005–2008 and 2017–2021, based on snow tracking on transect routes (681.2 km in total), and (2) to describe the presence and activity of roe deer in relation to human disturbances in selected urban forests in its reproductive period (March–August), based on camera trap survey (2019–2020, 859 observations, 5317 trap-days in total). The number of tracks was higher in natural habitat during all three periods, with the highest value in 2017–2021 (9.85/km/24h). The peak of roe deer activity was recorded at dusk, and it changed with moon phases between spring and summer. Landscape connectivity and level of light pollution did not affect the activity pattern of roe deer. Our research showed that roe deer inhabiting urban areas avoided human presence by using well-covered habitats and being active in periods when the level of human disturbance was lower.
Psychological Well-Being of Intellectually and Academically Gifted Students in Self-Contained and Pull-Out Gifted Programs

This study examined the psychological well-being of students enrolled in two gifted programs with different service delivery models. Participants were 292 fifth- and sixth-grade students (Mage = 11.70, SDage = 0.65) enrolled in a gifted math pull-out program (n = 103), a self-contained gifted program (n = 90), or a program providing no gifted services, which served as a control group (n = 99). Multiple differences in psychological well-being across programs were revealed in Hierarchical Linear Models, particularly in terms of math self-concept, loneliness, and maladaptive perfectionism. Students in the two gifted programs reported different patterns of psychological well-being when compared with students in the no gifted services control group. These differences suggest distinct social phenomena underlying the two different service delivery models.
‘When he turns his back to me, I give him the finger’: sexual violations in work environments and women’s world-making capacities

ABSTRACT In this article, we draw on 604 anonymous MeToo testimonies published in Iceland by women in different work sectors. Our main analytical focus is on women’s embodied experiences of sexual violations in the workplace, with an aim to explore how they tackle those violations. We use reflexive thematic analysis, and our first theme demonstrates how the women’s world and world-making capacities are perceived as shrinking as a result of harassment. This affects both their bodies and minds to the extent that they doubt their own judgment and grasp of reality. The violent acts become part of their psyche and leave them trapped in time and place. The second theme, workaround tactics for protecting their world-making capacities, describes how women seize opportunities to flag their agency even when they cannot change patriarchal strategies. The testimonies show how common and widespread women’s experiences of sexual violations are and thus call for a changed world order where men’s entitlement to women’s bodies and time in the work environment is removed.
Changes in the Vietnamese Timber Processing Industry: A Case of Quang Tri Province, North Central Region

Vietnam’s forestry policies have expanded the area of planted forests in order to meet the supply of raw materials for the timber processing industry. However, the diversity and volume of demand in the industry have also increased, and a shortage of raw materials can be assumed. For clarifying the correspondence of stakeholders, we explore changes in the resource supply behavior of forestry companies and procurement strategies of companies that manufacture lumber for glued laminated timber, medium density fiberboard (MDF) and wood pellets. Next, we discuss issues and future developments surrounding the supply and demand for timber from planted forests. According to a survey of Quang Tri Province, both industrial and on-farm tree planting play an important role in Vietnam’s wood industry. The origin of the supply has been categorized according to its purpose (products). On the other hand, with the declining supply of imported timber and natural forest timber, inquiries from sawmills and glued laminated timber factories for timber from planted forests have increased, and wood pellet manufacturers are facing competition for raw material procurement with MDF manufacturers, and the supply of timber from planted forests is becoming scarce. The key to the solution lies in improving the low productivity of current on-farm tree planting. To this end, forming farmer groups upon the acquisition of forest certification will help achieve economies of scale and bargaining power.
