Authors:   National Economics University, Thuy Linh LE
Published: September 2022

It cannot be denied that collaborative learning is regarded as a common approach in foreign language acquisition. However, it might be challenging to encourage all group members to equally and actively get involved in all group discussions and assignments. Therefore, this research proposes the application of monitoring sheet to deal with the problem of free-riding in collaborative activities in writing classes (when there are members hardly participating in group work). The research context was carried out in writing class of Business English majors at National Economics University. To begin with, the researcher clarified the integration of group work attached with its great advantages in teaching writing. Also, the arising phenomenon happening when group members not getting actively involved in the mutual tasks was emphasized. The evaluation methods for the innovation were comprised of interview, documentary analysis, observation and diaries which were developed with qualitative data. Responses from students in a writing class revealed that monitoring sheet should be considered as a solution to motivate students to work more interactively and make them feel more responsible for the mutual assignments.

Published: September 2022

Background: Distinguishing between seizure and neurally mediated syncope is challenging because of similar consequences and medical history. A head-up tilt test (HUTT) is a non-invasive, simple, and easy test to distinguish between epilepsy and syncope besides detailed history taking. Objectives: This study aimed to differentiate between epileptic events and reflex syncope (any different type of syncope) using the head-upright tilt test. Methods: We studied 59 patients (37 boys and 22 girls) between 4 to 18 years old (mean age, 10.5 ± 3.7 years) with a previous diagnosis of seizure who did not respond well to treatment. All patients underwent HUTT, and the test was positive in 26 patients. There were no significant differences in sex, age, provocative factors, associated syndrome, and family history between negative and positive groups. Results: There was a history of actual syncope in 26.9% of the positive tilt test group compared to 15.15% of the negative test group. Also, there was a positive family history of syncope in the positive tilt test group. Among 26 patients with a positive tilt test, 17 were diagnosed with vasovagal syncope (VVS) vasodepressor type and 9 with mixed type. Antiepileptic drugs were tapered for patients diagnosed with VVS, and they did not show any seizures after 18 ± 6 months of follow-up. Overemphasizing positive family history and inattention to history taking are 2 crucial factors leading to the misdiagnosis of epilepsy. Conclusions: Our study showed that HUTT is a non-invasive test that can be useful, especially for early and proper diagnosis in children with refractory epilepsy.
Time, Eternity, Relativity, and History
Authors: Mirus Christopher V. ,   Philosophy Documentation Center
Published: September 2022

What picture of reality emerges from the attempt to hold together the following three claims? (1) For temporal beings only the present, not the past or the future, exists. (2) For God, all times are present. (3) For temporal beings, what counts as present varies from individual to individual, as described in the theory of relativity. These claims jointly suggest that reality is always reality for—for God, or for this or that creature. This is neither relativism nor anti-metaphysical phenomenology; instead, it looks more like a modest but insistent development of the Thomistic doctrine of participation in being. Being is not a neutral and amorphous glop spread out before just any observer; rather, it belongs to and is measured by particular beings. Created being as a whole belongs to God (and, eventually, to the saints in God), whereas the share in being assigned to any creature is limited.

Background Although psoriasis burden and treatment have been well characterized in developed countries, there are scarce in-depth epidemiological studies in Latin American countries. Objectives To describe the sociodemographic and clinical features and the economic burden of psoriasis among children and adult patients from Colombia. Methods This cross-sectional study included patients from dermatology private practice offices, health provider institutions and hospitals in seven Colombian cities. We collected data on disease distribution, weight, height, body mass index, waist-hip ratio, disease severity, therapy, personal history of comorbidities, and direct costs. Multiple logistic regression analyses were conducted to assess the associations between severity scales and sociodemographic and clinical variables. Results Two-hundred-three patients (43.8% women, 56.2% men) with an age range between 7 to 89 years old were included. The main subtype was psoriasis vulgaris and mean age of diagnosis was 37.1 years. The most common comorbidities were obesity, hypertension, psoriatic arthritis, dyslipidemia and diabetes. Women had a significant increased odds of presenting with psoriatic arthritis. Body-mass-index and hypertension were significantly associated with a higher psoriasis severity, whereas being female and non-obese was associated with a lower risk. A third of the patients had a family history of psoriasis and sleeping disorders. Forty-one percent of participants either had no income or had an income below 224 US dollars per month and >20% of their income was spent on their disease. Conclusions This study is supported by robust scientific data and contributes to understanding the burden of psoriasis in Latin America. This study adds well-supported data through an in-depth clinical and economical characterization of Colombian children and adult patients with psoriasis and shows the high impact and burden of the disease on patients and their families.
Investigating Relationships Among Interoceptive Awareness, Emotional Susceptibility, and Fatigue in Persons With Multiple Sclerosis
Authors: Ware Megan , O’Connor Patrick , Bub Kristen , Backus Deborah , McCully Kevin
Published: September 2022

BACKGROUND

Fatigue is a particularly debilitating symptom for people with multiple sclerosis (MS). Although personality traits and MS have been studied, interoception and emotional susceptibility and their links to fatigue have not yet been explored.

METHODS

Study participants provided demographic information and completed standardized patient-reported outcomes of walking function, physical activity, subjective fatigue, interoceptive awareness, and emotional susceptibility. A subset of participants participated in semistructured interviews discussing fatigue, body sensations, emotions, and their effects on exercise. Quantitative data were analyzed using multiple regression. Qualitative data were analyzed using thematic analysis.

RESULTS

Mean ± SD Fatigue Severity Scale scores (5.0 ± 1.3) indicated that fatigue was a problematic symptom. Mean ± SD Multidimensional Assessment of Interoceptive Awareness, Version 2 (2.8 ± 0.6) and Emotional Susceptibility Scale (3.0 ± 1.0) scores indicated lower levels of interoceptive awareness and emotional susceptibility. Quantitative data indicated no relationship between fatigue and interoceptive awareness (β = −0.20; P = .88) and emotional susceptibility (β = 0.03; P = .83), and neither were these related to physical activity (β = −0.07; P = .64). Qualitative themes indicated strong fatigue experiences involving the whole body and individual limbs, anger and frustration, and effects on physical activity.

CONCLUSIONS

Physically active people with MS report strong sensations of fatigue closely linked to frustration and helplessness. There was agreement between qualitative and quantitative assessments of fatigue but dissonance regarding interoceptive awareness and physical activity. The practice of clinicians, particularly those involved with facilitating or planning physical activity for persons with MS, would benefit from these findings about fatigue.
The Effectiveness of Mexico's Humanitarian Diplomacy to Address the Challenges of a Pandemic
Authors: Dmitrieva Valentina Andreevna
Published: September 2022

The article proposes to consider the humanitarian diplomacy of Mexico during the SARS-CoV-2 pandemic, which the author sees as one of the tools of the state's foreign policy. Within the framework of the article, humanitarian diplomacy is studied for effectiveness in resolving socio-economic and political challenges that have arisen or worsened against the background of the pandemic, such as racism, poverty, lack of equipment, vaccines and personal protective equipment, the vulnerable situation of women, the deteriorating situation of the indigenous population, and the decline in the authority of the government. To assess the effectiveness, the author proposed a formula that allows calculating as a percentage how much humanitarian diplomacy has helped to cope with challenges. The scientific novelty of the study is an attempt to assess the effectiveness of humanitarian diplomacy in the context of resolving specific internal socio-economic challenges posed to the state. As a result of the study, it was revealed that humanitarian diplomacy is an effective auxiliary tool that can contribute to solving the problems that have arisen against the background of a humanitarian crisis. Nevertheless, the author notes that a number of deep problems require a comprehensive approach of the government and the use of various tools in addition to humanitarian activities. It is noted that the assessment of effectiveness in solving social challenges is complicated by the inability to obtain results immediately after the end of the project. Thus, the author denies the universality of humanitarian diplomacy as a tool for solving socio-economic challenges.
Camilo Castelo Branco: sátira, paródia e ceticismo
Authors: Motta Oliveira Paulo
Published: September 2022

The writer Camilo Castelo Branco is not particularly well known outside of the Portuguese or Spanish-speaking countries. In this article, following a brief consideration of the way in which his work was analyzed in the last century, the focus turns to the importance of satire in his work, and in particular parody he made of naturalist aesthetics in the late 1870s and early 1880s. Finally, the article seeks to evaluate how a parodic reading may establish a more accurate perspective on some of the characteristics present in his narrative work as a whole.
“Ó cóleras sagradas!/ Dai-me versos febris, agudos como espadas”: a sátira na poesia de Guerra Junqueiro
Authors: Nogueira Carlos
Published: September 2022

The aim of this paper is to determine and understand the ideas and poetics of the Portuguese writer Guerra Junqueiro’s (1850-1923) satire in verse. the article analyzes the literary content, form and stylistic strategies and takes into account Junqueiro’s historical, cultural and literary contexts. the idea of homeland fuels his satire to ridicule and punish both the internal agents that the poet considers responsible for the civilizational backwardness of his country (monarchists, King D. Carlos, the Church, the literati, etc.), and the external ones (England and its Portugal-related policies). the article demonstrates that Junqueiro’s satire is aimed to produce psychological and physical pain, which is metaphorized in the images of defense and punishment. Finally, it proves that this kind of fi gurative violence, in the context of a country in dire need of activism, paradoxically took the form of a nihilistic perspective expressed through a satirical verbalization that can, nonetheless, be considered as “active pessimism”.
O herói romântico parodiado por Camilo Castelo Branco
Authors: Pavanelo Luciene Marie
Published: September 2022

The image of Camilo Castelo Branco in literary historiography was shaped by a sentimental idealism and the tragedy of his impossible love relationships. However, the analysis of the male characters in novels such as Coração, Cabeça e Estômago and O Que Fazem Mulheres, proves that they share the same comic gaze of the Camilian narrator, who portrays them as a parody of the Romantic hero.
Pleasure vs. Desire: Towards the Feminist Road of Catherine Malabou
Authors: Košinaga Jelena
Published: September 2022

This paper considers the male-dominated philosophical traditions that have failed to adequately explicate the philosophical concept of desire. From psychoanalysis to Deleuze and Guattari, these traditions conceptualized desire as lack, loss, or a formless force. However, the feminist viewpoint proves these theories were inconsistent with and unaware of feminist interests. Therefore, the paper will posit that Catherine Malabou’s philosophy of pleasure has the capacity to dismantle the phallic economy and propose novel, plastic ways of perceiving femininity.
Raceless or Race-inflicted? Insecure and Anxious White Masculinities in Ann Petry’s Country Place
Authors: Abdullah Hogar
Published: September 2022

Ann Petry’s second novel, Country Place (1947), is classifi ed as a “white life novel” and serves as a medium to reflect on her interest in going beyond the usual “negro problem” in the African American protest novels of the 1940s to tackle the white peoples’ problems with other whites. This paper underlines the ways Petry challenges assumptions about whiteness as a universal convention and aims at making race visible by representing destabilized white (male) characters. By excavating issues of masculine anxiety and insecurity in a number of white characters, Petry endorses the progressive politics of her works in exposing racial prejudice and widening the defi nitions of racism.
Three-band plasmon induced transparency effect based on four-disk resonator coupled waveguide system

In order to reduce power consumption and realize ultrafast response time and dynamic tunability, a plasmonic waveguide system based on four disk resonators is designed. A plasmon induced transparency effect is theoretically analyzed by using two different methods: one is the direct destructive interference between bright mode resonator and dark mode resonator, and the other is the indirect coupling through a plasmonic waveguide. Owing to the giant effective nonlinear Kerr coefficient of the graphene-Ag composite material structure and the enhancement characteristics of slow light response to optical Kerr effect, the pump intensity of PIT system for changing the phase shift of transmission spectrum is greatly reduced. An ultrafast response time of 1 ps is achieved, and 0.4π, 0.8π, 1.2π, 1.6π and 2π-phase shift of the transmission spectrum in the plasmon induced transparency system are achieved with the intensity of the pump light as low as 2.34, 4.68, 7.02, 9.36, 11.7 MW/cm–2, respectively. In this work, a plasmonic waveguide coupled directly by two small disk resonators is employed, because two small disk resonators play a role of the slit between the waveguide and the resonators, and also act as two separate resonators side-coupled with a plasmonic waveguide, which leads to the more efficient coupling of electromagnetic energy in the waveguide into the big disk resonators to form resonance and easier storage of light in the resonator. The triple-band plasmon induced transparency (PIT) effect and slow light properties of the model are analyzed by the expression of the deduced theoretical transmittance based on the coupled mode theory, indicating that they are very consistent with the finite-difference time-domain simulations. The results show that the transmission peak of the system is over 80% and the maximum group index is as high as 368. Furthermore, the disk resonators are easy to fabricate and the size of the entire PIT structure is < 0.5 μm2, which is beneficial to the design of optoelectronic device on-chip integration. The research results have important application prospects in highly integrating optical circuits and networks, and also provide the ideas for the design and fabrication of multi-channel optical filter and light storage devices with low power consumption, ultrafast nonlinear response, ultracompact and dynamical tunability.
Input-output characteristics of single-mode cavity with multiple coherently coupled artificial atoms

Published: September 2022

In previous cavity quantum electrodynamics (QED) systems, atomic gas is usually treated as single atoms, thereby resulting in phenomena such as Rabi splitting, and single-photon blocking. Benefiting from the development of superconducting circuit QED, the superconducting quantum interference devices (SQUIDs) can be regarded as artificial atoms, and the detuned coupling of them through LC harmonic oscillators will constitute an equivalent coherent coupling between artificial atoms. According to this, we study the effect of multiple artificial atoms with coherent coupling on the input and output of a single-mode cavity, and analyze the transmission spectrum from the perspective of decorated state. We find that single-mode cavities containing multiple artificial atoms with coherent coupling have significantly different transmittances from cavities containing single atoms, the transmission spectra of which are correlated with the coherent coupling coefficients between the artificial atoms, and the coupling coefficients between the cavity modes and the artificial atoms, and we also find that both the cavity mode leakage rate and the artificial atom decay rate are related to each other. And as the number of artificial atoms increases, the number of transmission peaks does not increase, and there are only three transmission peaks at most. In order to explain the law of this transmission spectrum, we quantize both artificial atoms and cavity modes, and calculate the eigenvalues and eigenstates of the whole in a single quantum case. In principle, if there are several particles, they will form several decorative states, and there will theoretically appear several transmission peaks. However, we find that there are some decorated states that do not contain the photonic component and thus do not contribute to the transmission peak. From the specific form of these decorated states, many of them have the property of many-body entanglement. Therefore, using such a single-mode cavity containing multiple coherently coupled artificial atoms, we can construct the required many-body entangled state by simply inputting weak monochromatic light, and at the same time, we can sense the forms of multi-body entanglement states in the cavity through the change of transmittance.

Authors: Reddi Neerajakshi , Sanapala Sobharani , Budumuru Radhika
Published: September 2022

Introduction: The irrational and inappropriate use of beta lactam antimicrobial drugs has led to the advent of Extended Spectrum Beta-Lactamase (ESBL) resistant strains. ESBL producing Enterobacteriaceae strains are frequent causative agents both in community and in acquired nosocomial infections and Urinary Tract Infections (UTI). The phenotypic confirmatory tests rarely identify all ESBLs. Chrom ID (Chromogenic identification Media) ESBL – Bx (bioMerieux) is a completely new and innovative chromogenic medium designed specifically for the screening of ESBL producing Enterobacteria directly from urine samples. It is a ready to use selective media which is sensitive and specific for rapid and presumptive identification of ESBL producing Enterobacteriaceae. Aim: Early detection of ESBL producing Enterobacteriaceae directly from urine samples on chromogenic medium (Chrom ID- ESBL- Bx) and confirmation of ESBL producing Enterobacteria using Disc Potentiation Test (DPT). Materials and Methods: The present cross-sectional study was conducted in the Department of Microbiology, Rangaraya Medical College, Kakinada, Andhra Pradesh, India from November 2019 to March 2020 (five months duration). The study was done on 70 urine samples from patients with UTI. All samples were subjected to wet mount, inoculated directly for culture on Chrom ID ESBL- Bx agar and MacConkey agar. Antibiotic Susceptibility testing of ceftazidime and cefotaxime was done by Kirby-Bauer disc diffusion method and conformation of ESBL production by DPT using Clinical and Laboratory Standards Institute (CLSI) method. The Statistical Package for the Social Sciences (SPSS) Statistical package version (18.0) was used. Results: A total of 56 (80%) isolates were obtained from 70 urine samples, out of them 28 (50%) were Escherichia coli, 21 (37.5%) were Klebsiella spp., 7 (12.5%) were Proteus spp., 23 (82.14%) isolates of Escherichia coli, 15 (71.43%) of Klebsiella spp., 6 (85.71%) of Proteus spp., isolated were screened positive using Chrom ID ESBL-Bx agar. About 44 (78.57%) of total Enterobacteria (56) were screened for ESBL production. 20 (86.96%) of Escherichia coli, 11 (73.33%) of Klebsiella spp., and 5 (83.33%) of Proteus spp., that were screened positive using Chrom ID ESBL agar were confirmed (by DPT) as ESBL producers and 2 (16.6%) of total (12) isolates that were screened negative by Chrom ID ESBL agar were confirmed as ESBL producers when screened and confirmed by DPT. So sensitivity and specificity CHRO Magar was 94.73% and 55.5%. Conclusion: ESBL continues to become a serious public health threat. Results from present study showed that CHROMagar ESBL has a high sensitivity and a convenient method for making provisional diagnosis of drug resistant Enterobacterial infections in 24 hours. Chrom ID ESBL- Bx agar medium allows easy differentiation of different bacteria based on colony colouration.

The study examined various perspectives on Voluntary Savings and Loans Association (VSLA) activities and household food security in Uganda. Specifically, the study examined the effect of VSLA on household food Availability, established the contribution of VSLA on household food Access, and determined the effects of VSLA on household food Stability. The study adopted a literature review approach to collect information. The results suggest a positive relationship between VSLA activities and household food security in Uganda. It further reveals that VSLA activities affect food availability, food accessibility and food stability. It is concluded that if the government of Uganda can improve on the quality of VSLA activities, the level of household food security will improve. This study contributes to the understanding of the association between VSLA activities and household food security in the country. Therefore, for improved household food security, it is encouraged that the leadership of Local Governments focus more attention on mobilising local communities to join VSLA groups so that they can access affordable capital to increase their level of production, which can translate  into sustainable household food security in the long run.

Substance abuse is a global public health problem with physical, social, psychological, economic, and health implications. Adolescent age is an important transitional period and comes with a high level of vulnerability, curiosity, experimentation, and making choices that may be detrimental to them in the long run. The problem of substance abuse has become very popular among adolescents, several researchers from different parts of the world have reported a high prevalence rate of substance abuse among teenagers and its resultant health and social problems. This study identified four different levels of factors that influence substance abuse among teenagers which includes family-related problems, and individual, psychological and social factors. Different preventive measures have also been identified, highlighting roles that should be played by family, the community, schools, as well as the government. These measures will have a great impact on curbing the menace of substance abuse among young people in societies, they will be able to avoid risky behaviors, function effectively, and achieve their dreams.

Background

There is scattered evidence of the impact of workplace interventions in improving employees' physical activity. This systematic review was performed to evaluate the strategies of workplace interventions and their effectiveness, as reported in primary studies.

Method

Primary experimental trials, both randomized controlled trials (RCTs) and non-RCTs, which examined interventions to increase healthy adult employees' physical activity were included in this review. Studies in English or Persian published between 2009 and 2019 with access to full text of resources were considered. Google Scholar, PubMed, Web of Science, Scopus and Cochrane Library, ProQuest (Thesis) and World Health Organization Clinical Trial Registration Databases and Persian databases such as SID, Magiran, IranMedex, Irandoc were searched. All the stages of review were conducted based on PRISMA. RoB and ROBINS-I were used to assess the risk of bias of the primary studies.

Results

Thirty-nine studies, with a total of 18 494 participants, met the inclusion criteria. Of these, 22 were RCTs, 17 were non-RCTs. Effective interventions were reported in 15 RCTs and 14 non-RCTs. Four main strategies of interventions were identified, consisting of motivation and support; monitoring and feedback; information and education; and activity. Thirteen different behavior change techniques (BCT) were identified with self-determination theory (SDT) being the most frequent behavior change theory used.

Conclusion

It seems that a multi-strategy intervention that one of the strategies of which is physical activity in the workplace (Activity), the use of behavioral change theories, especially SDT, may be indicative of a more effective intervention. It is recommended that BCTs be considered when designing physical activity interventions.

Loss of the histone demethylase KDM5D (lysine‐specific demethylase 5D) leads to in vitro resistance of prostate cancer cells to androgen deprivation therapy (ADT) with and without docetaxel. We aimed to define downstream drivers of the KDM5D effect. Using chromatin immunoprecipitation sequencing (ChIP‐seq) of the LNCaP cell line (androgen‐sensitive human prostate adenocarcinoma) with and without silenced KDM5D, MYBL2‐binding sites were analyzed. Associations between MYBL2 mRNA expression and clinical outcomes were assessed in cohorts of men with localized and metastatic hormone‐sensitive prostate cancer. In vitro assays with silencing and overexpression of MYBL2 and KDM5D in androgen receptor (AR)‐positive hormone‐sensitive prostate cancer cell lines, LNCaP and LAPC4, were used to assess their influence on cellular proliferation, apoptosis, and cell cycle distribution, as well as sensitivity to androgen deprivation, docetaxel, and cabazitaxel. We found that silencing KDM5D increased histone H3 lysine K4 (H3K4) trimethylation and increased MYBL2 expression. KDM5D and MYBL2 were negatively correlated with some but not all clinical samples. Higher MYBL2 expression was associated with a higher rate of relapse in localized disease and poorer overall survival in men with metastatic disease in the CHAARTED trial. Lower MYBL2 levels enhanced LNCaP and LAPC4 sensitivity to androgen deprivation and taxanes. In vitro, modifications of KDM5D and MYBL2 altered cell cycle distribution and apoptosis in a cell line‐specific manner. These results show that the transcription factor MYBL2 impacts in vitro hormone‐sensitive prostate cancer sensitivity to androgen deprivation and taxanes, and lower levels are associated with better clinical outcomes in men with hormone‐sensitive prostate cancer.

Purpose

To estimate the clinical impact of differences between delivered and planned dose using dose metrics and normal tissue complication probability (NTCP) modeling.

Methods

Forty‐six consecutive patients with prostate adenocarcinoma between 2010 and 2015 treated with intensity‐modulated radiation therapy (IMRT) and who had undergone computed tomography on rails imaging were included. Delivered doses to bladder and rectum were estimated using a contour‐based deformable image registration method. The bladder and rectum NTCP were calculated using dose–response parameters applied to planned and delivered dose distributions. Seven urinary and gastrointestinal symptoms were prospectively collected using the validated prostate cancer symptom indices patient reported outcome (PRO) at pre‐treatment, weekly treatment, and post‐treatment follow‐up visits. Correlations between planned and delivered doses against PRO were evaluated in this study.

Results

Planned mean doses to bladder and rectum were 44.9 ± 13.6 Gy and 42.8 ± 7.3 Gy, while delivered doses were 46.1 ± 13.4 Gy and 41.3 ± 8.7 Gy, respectively. D10cc for rectum was 64.1 ± 7.6 Gy for planned and 60.1 ± 9.3 Gy for delivered doses. NTCP values of treatment plan were 22.3% ± 8.4% and 12.6% ± 5.9%, while those for delivered doses were 23.2% ± 8.4% and 9.9% ± 8.3% for bladder and rectum, respectively. Seven of 25 patients with follow‐up data showed urinary complications (28%) and three had rectal complications (12%). Correlations of NTCP values of planned and delivered doses with PRO follow‐up data were random for bladder and moderate for rectum (0.68 and 0.67, respectively).

Conclusion

Sensitivity of bladder to clinical variations of dose accumulation indicates that an automated solution based on a DIR that considers inter‐fractional organ deformation could recommend intervention. This is intended to achieve additional rectum sparing in cases that indicate higher than expected dose accumulation early during patient treatment in order to prevent acute severity of bowel symptoms.
Adaptive cooperative control for air‐ground systems with actuator saturation under disturbances
Authors: Yang Hongjiu , Wang Jin , Li Hongbo , Zuo Zhiqiang
Published: September 2022

In this article, an adaptive cooperative control strategy is proposed for an air‐ground system with actuator saturation. The air‐ground system with actuator saturation includes a ground vehicle with road bumps and a quadrotor with gust winds. The adaptive cooperative control strategy is composed of four tracking differentiators, four adaptive extended state observers and two adaptive integral SMC laws. Based on Silverman canonical transformation and pole placement, the adaptive extended state observers are designed to estimate disturbances from the road bumps and gust winds. The adaptive integral SMC laws are proposed to achieve cooperation between the ground vehicle and the quadrotor in the air‐ground system with actuator saturation. Simulation results are provided to show effectiveness of the adaptive cooperative control strategy by a ground vehicle and a quadrotor.
