A rapidly retreating, marine-terminating glacier's modeled response to perturbations in basal traction

Abstract Upernavik Isstrøm, a marine glacier undergoing rapid retreat, is simulated by forcing a numerical model with ocean-driven melt. A review of processes driving retreat led us to hypothesize that a glacier undergoing rapid retreat may be less sensitive to perturbations in the balance of forces than a glacier that is undergoing moderate changes or a glacier in steady state. Numerical experiments suggest this is not the case, and that a system in rapid retreat is as sensitive to basal traction perturbations as a system that is near to steady state. This result is important when considering other glacier systems experiencing marine-forced retreat. While the ice–ocean interface is of primary importance, additional perturbations from meltwater-forced decoupling of the glacier from its bed continue to feature in glacier dynamics.
Research on Optimal Route of Road Transport Network with Restrictive Conditions

According to the basic principles of the shortest route algorithm in Graphic Theory, an algorithm on the question of the optimal route for the network with restrictive path is brought forward. Firstly, the road network is transformed into the one without any restrictive conditions. Then the model for optimizing the route on the road network is built taking least traveling time as the objective. Finally, the traditional Dijkstra algorithm is used to solve the problem. The result of computer simulation shows that this method is practical and feasible. The model and its algorithm could be used to get the optimal route on the road transport network with restrictive conditions in a very short time and to realize the function of guiding drivers to the optimal route in an inducement system.
Reinforcing Communication on the Internet of Aerial Vehicles

The increasing demand for green Unmanned Aerial Vehicles (UAVs) in civil and military applications has been noticed in the last few decades. As a result, Flying Ad-hoc Networks (FANETs) caught the attention of industries and academia. Due to its exceptional features, it has replaced other traditional networks deployed in all circumstances. However, UAVs have limited resources, and efficient use of these resources is critical for maximizing network lifetime and Quality of Experience (QoE). In this paper, Fisheye State Routing (FSR) protocol is exploited for communication between several UAVs in a topology changing network employing a 3x3 Manhattan grid mobility model. Several network parameters, i.e., packet delivery and drop ratios, end-to-end delay, channel utilization, dropped packet ratio behavior, throughput, jitter, are employed to validate FSR’s effectiveness in FANETs. Results analysis is carried out in two different network scenarios with twenty and thirty nodes, respectively. The proposed routing protocol has effectively utilized UAV resources with 46% and 53% packet delivery ratios with maximum channel utilization and throughput over time in both scenarios. Moreover, FSR has 0.010 and 0.253 seconds delay and minimum jitter in twenty and thirty nodes comparatively influential among other routing protocols in end-to-end delay. The proposed approach provides excellent results compared to several other topology-based routing protocols and efficiently utilizes onboard resources.
Méthode de recherche qualitative utilisant les sites de rencontre par Internet : expérimentation d’une recherche portant sur les sexualités entre hommes

Résumé Cet article s’interroge sur la compatibilité d’Internet à des fins de recherche qualitative lorsque la thématique touche à l’intimité. Dans le cadre de la lutte contre le sida, les comportements sexuels ont suscité de nombreuses enquêtes quantitatives à visée épidémiologique. L’étude des aspects sociaux du sida a, pour sa part, érigé l’intime en objet de recherche. En matière de relations à caractère homosexuel, l’émergence d’Internet a créé, en précédant la rencontre physique, une extension de l’espace de socialisation regroupant de manière virtuelle des hommes désirant avoir des relations sexuelles avec d’autres hommes. De ce fait, Internet présente un intérêt heuristique à être employé pour mener des recherches qualitatives. En outre, il présente de nombreux avantages en termes d’anonymat, accessibilité et commodité d’emploi. Toutefois, les inconvénients de la méthode ne sont pas à négliger. Les questions d’ordre éthique sont notamment à évaluer. Mots clés MÉTHODE DE RECUEIL D’INFORMATIONS, SITES DE RENCONTRE SUR INTERNET, BISEXUALITÉ, COMPORTEMENTS À RISQUE
Land policy by other means: democracy and the military in contemporary urban Brazil

This paper explores the relationship between the Armed Forces and the land market in Brazilian metropolises. Highlighting the important of the urban dimensions of this relationship, this research sheds light on agents usually invisibilized by the literature in an attempt to understand their role in land policy. The practices, meanings, and outcomes of the Armed Forces’ involvement is reflectedin the decision-making conditions that characterize Brazilian democracy. By establishing a dialogue with a well-known aphorism from Prussian strategist Carl von Clausewitz, that war is the continuation of politics by other means, we present and analyze land policies as continued by war operators. As we analyze military management practices and the commodification of public spaces, we find the city’s production dynamics are galvanized by Army generals. Beyond security, surveillance, and population control, the Armed Forces have carried out a complex set of strategies regarding the occupation of cities, fueling debates around the nature of democracy underway in contemporary Brazil.
Investigating the Emission of Hazardous Chemical Substances from Mashrabiya Used for Indoor Air Quality in Hot Desert Climate

Dubai has the reputation of a continuously growing city, with skyscrapers and mega residential projects. Many new residential projects with poor choices of material and ventilation have led to a faster rise in sick building syndrome (SBS) in Dubai than in any other country, and the IAQ (indoor air quality) has become more critical. Volatile organic compounds (VOCs) and formaldehyde (HCHO) affect the health of residents, producing the phenomenon known as SBS (sick building syndrome). It has been reported that wood materials used for furniture and wooden windows and doors are a significant source of indoor air pollution in new houses. This paper aims to identify the factor elements emitting harmful chemical substances, such as VOCs and HCHO, from wooden mashrabiya (traditional Arabic window) by examining the characteristics of the raw and surface materials through test pieces. As a methodology, a small chamber system was used to test the amount of hazardous chemicals generated for each test piece. For Total volatile organic compounds (TVOC) and HCHO, the blank concentration before the injection and the generation after seven days were measured. The results showed that to reduce TVOC, it is necessary to secure six months or more as a retention period for raw materials and surface materials. The longer the retention period, the smaller the TVOC emission amount. In the case of mashrabiya, an HCHO low-emitting adhesive and maintenance for one month or more are essential influencing factors. It was proven that using raw materials with a three-month or more retention period and surface materials with a one-month or more retention period is safe for indoor mashrabiya. This study is the first study in the Middle East to identify factors and characteristics that affect the emission of hazardous chemicals from wood composite materials, such as wood mashrabiya, that affect indoor air quality in residential projects in Dubai. It analyzes the correlation between emission levels and the retention period of raw and surface materials, in order to provide a new standard for indoor air pollutants.
FRAMEWORK FOR GAP ANALYSIS BASED ON PRIORITY OF SOFTWARE DEPLOYMENT REQUIREMENTS

Software deployment is an important phase of the software development life cycle because it makes software available for the customers. This process needs collaboration between developers and customers. Usually, there are many particular requirements requested from customer aspect. However, software deployment is not directly related to the development of software main functions. Many developers, therefore, tend to underinvest in this process. The critical consequence of a deployment failure is that software may be not available on the targeted environment. This paper presents a framework for gap analysis based on software deployment requirements prioritization. It supports an analysis of a large volume of requirements in order for developer to perform deployment process. The framework is consisted of five related procedures; Project Establishment Phase, Software Deployment Requirements Prioritization Phase, Software Deployment Reference Process Prioritization Phase, Gap Analysis Phase, and Gap Evaluation Phase. Each organization can apply this framework to evaluate gaps between the software deployment requirements and the deployment process according to what the customers really need and improve deployment process to satisfy user need.
A 1.15-mW Low-Power Low-Complexity Reconfigurable FM-UWB Transmitter

A 1.15-mW 3.75–4.25-GHz frequency-modulated ultrawideband (FM-UWB) transmitter (TX) is fabricated in 65-nm CMOS, with digitally reconfigurable subcarrier frequencies, UWB bandwidth, and radio frequency (RF) frequency band. Low-complexity submodules are utilized with significant power savings. An ultralow-current hybrid module is for bandgap reference (BGR) and power-ON reset (POR), and a single-ended crystal oscillator (XO) generates a 12-MHz clock reference. A dual-path ring voltage-controlled oscillator (VCO) conducts linear RF FM, followed by a push–pull power amplifier (PA) for 100-kb/s wireless data transmission. A differential relaxation oscillator (OSC) is for subcarrier generation, and an intermittent dual-mode frequency calibration loop ensures system robustness. Experimental results show that the presented FM-UWB TX successfully generates an Federal Communications Commission (FCC)-compliant UWB signal, with an energy efficiency of 11.5 nJ/bit and an active area of 0.21 mm<sup>2</sup> from a 1-V supply. The 2.25-<inline-formula> <tex-math notation="LaTeX">$\mu \text{A}$ </tex-math></inline-formula> hybrid BGR and POR achieves a temperature coefficient of 32 ppm/°C, a line regulation of 2.3%/V, a supply-ramp-rate-tolerant power-ON, and brown-out function. The 40-<inline-formula> <tex-math notation="LaTeX">$\mu \text{W}$ </tex-math></inline-formula> XO features a low-frequency inaccuracy of 4 ppm/V. The 40-<inline-formula> <tex-math notation="LaTeX">$\mu \text{A}$ </tex-math></inline-formula> relaxation OSC provides the reconfigured two-frequency shift keying (FSK) triangular amplitude and frequency. The 2.79–5.18-GHz 0.6-mW ring VCO is capable of providing the phase noise performance of −77 dBc/Hz at the 1-MHz offset, followed by the 0.45-mW PA having the output power higher than −14 dBm and the peak power-added efficiency (PAE) of 29.6%. All these benefit low-power low-cost TX implementation, where the carrier and subcarrier frequencies are calibrated by an intermittent digital loop with omitted power dissipation.
A Two-Branch CNN Fusing Temporal and Frequency Features for Motor Imagery EEG Decoding

With the development of technology and the rise of the meta-universe concept, the brain-computer interface (BCI) has become a hotspot in the research field, and the BCI based on motor imagery (MI) EEG has been widely concerned. However, in the process of MI-EEG decoding, the performance of the decoding model needs to be improved. At present, most MI-EEG decoding methods based on deep learning cannot make full use of the temporal and frequency features of EEG data, which leads to a low accuracy of MI-EEG decoding. To address this issue, this paper proposes a two-branch convolutional neural network (TBTF-CNN) that can simultaneously learn the temporal and frequency features of EEG data. The structure of EEG data is reconstructed to simplify the spatio-temporal convolution process of CNN, and continuous wavelet transform is used to express the time-frequency features of EEG data. TBTF-CNN fuses the features learned from the two branches and then inputs them into the classifier to decode the MI-EEG. The experimental results on the BCI competition IV 2b dataset show that the proposed model achieves an average classification accuracy of 81.3% and a kappa value of 0.63. Compared with other methods, TBTF-CNN achieves a better performance in MI-EEG decoding. The proposed method can make full use of the temporal and frequency features of EEG data and can improve the decoding accuracy of MI-EEG.
Aboveground biomass accumulation and tree size distribution in seasonal Atlantic Forest restoration sites

Tropical forests undergoing restoration can present high biomass accumulation rates, especially in the first 20 years. However, native species reforestations often present a bias toward fast growth, low wood density, and small maximum adult size species, contrasting with most mature forest species. Since tree species adult size and wood density are key traits that influence biomass accumulation, these induce uncertainty regarding carbon uptake capabilities of restoration projects in the long term. We compared the density of individuals (DI), basal area (BA), aboveground biomass (AGB), and weighted average wood density (WDW) in 13–14‐year‐old restoration sites and in mature seasonal Atlantic Forest fragments. We also assessed the contribution of pioneer and non‐pioneer and planted and non‐planted species on these variables at restoration sites. Furthermore, we investigated the DI and WDW for saplings and seedlings, in order to foresee changes in forest structure that may result from natural recruitment of dense‐wood mature species. The BA and WDW at restoration sites were similar to forest fragments, except for large trees (DBH ≥50 cm). Restoration sites recovered AGB to the level of forest fragments only for the smaller size class (DBH 5–19.9 cm). Planted pioneer and non‐pioneer species accumulated the greatest AGB (93%), BA (94%), and DI (90%) at restoration sites. The DI of non‐planted non‐pioneer species with higher WDW increased among saplings and seedlings at restoration sites. The presence of species with a larger adult size and higher WD may indicate long‐term increase in biomass accumulation at restoration sites.
Ultrasound Image under Artificial Intelligence Algorithm to Evaluate the Intervention Effect of Accelerated Rehabilitation Surgery Nursing on Laparoscopic Hysterectomy

To explore the application value of accelerated rehabilitation surgery (ERAS) nursing in laparoscopic total hysterectomy, 120 patients who underwent laparoscopic total hysterectomy for benign uterine diseases in the hospital were selected as the research object. According to different nursing schemes, they were divided into 60 cases in the experimental group (ERAS nursing program) and 60 cases in the control group (traditional perioperative nursing). All patients underwent postoperative ultrasonography, and the intraoperative and postoperative rehabilitation indexes of the two groups were analyzed. Moreover, an improved standard Capon beamforming (ISCB) algorithm is proposed, which is compared with SCB algorithm, sequential regression algorithm (SER), and recursive least square (RLS) algorithm. The results showed that the center average power and background average power (−46.92, −33.85) of the ISCB algorithm were significantly lower than those of SCB algorithm (−36.18, −23.64), SER algorithm (−39.02, −27.31), and RLS algorithm (−34.88, −24.66), while the contrast and resolution (19.11, 15.57) were significantly higher than those of SCB algorithm (12.74, 9.01), SER algorithm (13.86, 7.89), and RLS algorithm (13.26, 8.26) (P < 0.05). The anal exhaust time (11.84 ± 2.15 hours), analgesic effect score (3.37 ± 1.03 points), hospitalization days (3.72 ± 0.74 days), and hospitalization expenses (11859.03 ± 735.24 ¥) in the experimental group were significantly lower than those in the control group (20.95 ± 3.44 hours, 6.12 ± 1.46 points, 5.48 ± 0.91 days, 16135.22 ± 680.55 ¥) (P < 0.05). The score of NRS evaluation scale in the experimental group (2.28 ± 0.37) was significantly better than that in the control group (4.09 ± 0.65) (P < 0.05). The proportion of patients in the experimental group (very satisfied + satisfied + generally satisfied) (100%) was significantly better than that in the control group (71%), and the difference was statistically significant (P < 0.05). In the experimental group, there were 2 cases of postoperative fever, 1 case of nausea and vomiting, and 2 cases of lower extremity venous thrombosis. In the control group, there were 4 cases of postoperative fever, 4 cases of nausea and vomiting, and 2 cases of lower extremity venous thrombosis. In summary, ultrasound imaging based on the ISCB algorithm can display the pelvic floor structure of patients undergoing laparoscopic total hysterectomy with high quality and improve the diagnostic rate of doctors. ERAS nursing can accelerate patients' postoperative rehabilitation, reduce postoperative pain, and improve patients' satisfaction. It was worthy to be popularized and applied in the clinic.
Speaking Silence: Abusive Supervision, Subordinates’ Citizenship Behavior, and Whistleblowing Intention

This study investigated the relationship between abusive supervision and subordinates’ citizenship behavior, as well as subordinates’ whistleblowing intention as a reactionary outcome of supervisory abuse. Data was collected from 180 Nigerian healthcare assistants using a structured questionnaire. Additionally, 20 semi-structured interviews were conducted. The study found a negative relationship between abusive supervision and subordinates’ citizenship behavior. Also, the relationship between abusive supervision and subordinates’ whistleblowing intention was not significant. Theoretical and practical implications are discussed in the light of contextual peculiarities. Recommendations advocate the urgency of cultural re-engineering to mitigate the vicious cycle of supervisory abuse and encourage the emergence of abusive supervisors from the toxic dark side into the light of inspirational leadership.
Price Transmission Effect of Establishing FTA with African Countries from the Perspective of Trade Facilitation

The present article introduces the price transmission effect of establishing free trade areas with African countries from the perspective of trade facilitation. Studies on China-Africa economic cooperation, tariff reduction effects, trade facilitation effects, and price transmission effects in free trade areas were reviewed. The existing literature rarely incorporates tariffs, trade facilitation, and price transmission mechanisms into the research when studying the effects of free trade areas. The present article introduces trade facilitation into the research field of China-Africa cooperation. Taking the China-Mauritius free trade area as an example, the Global Trade Analysis Project model is used to study the price transmission effect after the establishment of the China-African free trade area. Create a model and motivation for other countries to establish free trade areas with African countries. The main conclusions are as follows: China-Mauritian free trade area has improved not only the terms of trade, GDP, and social welfare of the two countries, but also other African countries. This improvement effect mainly comes from the improvement of trade facilitation, and the contribution of zero tariff policy is relatively small. The domestic price changes in many industrial sectors of the two countries showed a significant increase, while the import prices generally showed a downward trend. Therefore, countries should actively participate in the process of global economic integration, and, in the negotiation of trade liberalization, both sides should adopt differentiated negotiation strategies and improve the weak aspects of trade facilitation, respectively, to achieve a win-win situation.
Lime Peel Oil–Incorporated Rosin-Based Antimicrobial In Situ Forming Gel

Localized intra-periodontal pocket drug delivery using an injectable in situ forming gel is an effective periodontitis treatment. The aqueous insoluble property of rosin is suitable for preparing a solvent exchange-induced in situ forming gel. This study aims to investigate the role of incorporating lime peel oil (LO) on the physicochemical properties of injectable in situ forming gels based on rosin loaded with 5% w/w doxycycline hyclate (DH) in dimethyl sulfoxide (DMSO) and N-methyl pyrrolidone (NMP). Their gel formation, viscosity, injectability, mechanical properties, wettability, drug release, and antimicrobial activities were evaluated. The presence of LO slowed gel formation due to the loose precipitate formation of gel with a high LO content. The viscosity and injectability were slightly increased with higher LO content for the DH-loaded rosin-based in situ forming gel. The addition of 10% LO lowered gel hardness with higher adhesion. LO incorporation promoted a higher drug release pattern than the no oil-added formulation over 10 days and the gel formation rate related to burst drug release. The drug release kinetics followed the non-Fickian diffusion mechanism for oil-added formulations. LO exhibited high antimicrobial activity against Porphyromonas gingivalis and Staphylococcus aureus. The DH-loaded rosin in situ forming gel with an addition of LO (0, 2.5, 5, and 10% w/w) inhibited all tested microorganisms. Adding 10% LO to rosin-based in situ forming gel improved the antimicrobial activities, especially for the P. gingivalis and S. aureus. As a result, the study demonstrates the possibility of using an LO amount of less than 10% loading into a rosin-based in situ forming gel for efficient periodontitis treatment.
