Crashed! Why Drone Delivery Is Another Tech Idea not Ready to Take Off

The objective of this study was to examine why drone delivery is another tech idea not ready to take off. Qualitative methods, which involved inductive, exploratory and interpretivism approaches, were used in this conceptual study. The inductive approach was used to generate propositions based on secondary data obtained from journal articles, authorized website contents, and books. On the other hand, exploratory and interpretivism approaches were used to undertake in-depth analysis and to have a complete description and understanding of the factors that shape consumers’ behavioural intentions to use drone food delivery services, respectively. Based on research findings and news related to consumers’ behavioural intentions to use drone delivery services, conceptual frameworks have been proposed to show the four main independent variables, which are functions, hedonic motivation, cognition, and social factors, that affect the dependent variable, which is behavioural intentions of consumers to use drone for food delivery services. Overall, factors that were hindering consumers’ behavioural intentions to use drone food delivery services were consumers’ unfamiliarity and negative perceptions toward drone delivery in that it is unregulated, dangerous, risky, lack of quantified risk assessments, intimidating, related to military and defence, and lengthy in the process to obtain authority’s permission to operate food delivery services by drones. Nevertheless, they may be influenced to use drone delivery if their friends and family were using it.
QRS Complex Wavelet Analysis Can Distinguish Patients with and without Heart Failure, in the Presence of Left Bundle Branch Block

Background: Left bundle branch block (LBBB) in heart failure (HF) patients is a negative predictor of survival. This pattern is occasionally recorded in individuals without structural heart disease. The LBBB morphology has not been previously analyzed in a time-frequency domain using wavelet analysis), and thus the factors distinguish LBBB patients from individuals without structural heart disease remain unexplored. The purpose of this analysis was to investigate the variations and the differences in LBBB morphology between healthy individuals with LBBB and patients with HF and LBBB. Methods: HF patients with LBBB and individuals with LBBB were included in this study. Signal-averaged 90-second Holter monitor recordings were extracted from each subject in orthogonal leads. QRS decomposition in 9 time-frequency bands (TFB) was performed using Complex Morlet wavelets transformation, while the mean and maximum energies of the QRS complexes were calculated for each of the 9 TFBs. The wavelet parameters of HF patients were compared with those of healthy controls. Results: Wavelet analysis was performed on ECG recordings of 69 HF patients and 17 individuals without cardiac disease. The mean and max wavelet energies of the QRS complex in all TFBs were higher for heart failure patients with LBBB, as compared to healthy individuals with LBBB. Differences were statistically significant in TFB4 and TFB7 (max energy, axis X), TFB4 and TFB7 (max energy, axis Y) and TFB4 and TFB7 (mean energy, axis Y). A multivariate logistic regression model, comprising of the aforementioned wavelet parameters, proved reasonably capable of distinguishing between HF patients and healthy controls with LBBB (AUC=0.854, 80.2% sensitivity and 80.3% specificity). Conclusion: QRS wavelet analysis revealed differences in the template of the QRS complex between healthy individuals with LBBB and heart failure patients with LBBB. This feature could be used as part of the diagnostic algorithm, a possibility that should be investigated further.
Strengthening of the Efferent Olivocochlear System Leads to Synaptic Dysfunction and Tonotopy Disruption of a Central Auditory Nucleus

The auditory system in many mammals is immature at birth but precisely organized in adults. Spontaneous activity in the inner ear plays a critical role in guiding this maturation process. This is shaped by an efferent pathway that descends from the brainstem and makes transient direct synaptic contacts with inner hair cells. In this work, we used an α9 cholinergic nicotinic receptor knock-in mouse model (of either sex) with enhanced medial efferent activity (Chrna9L9′T, L9′T) to further understand the role of the olivocochlear system in the correct establishment of auditory circuits. Wave III of auditory brainstem responses (which represents synchronized activity of synapses within the superior olivary complex) was smaller in L9′T mice, suggesting a central dysfunction. The mechanism underlying this functional alteration was analyzed in brain slices containing the medial nucleus of the trapezoid body (MNTB), where neurons are topographically organized along a mediolateral (ML) axis. The topographic organization of MNTB physiological properties observed in wildtype (WT) was abolished in L9′T mice. Additionally, electrophysiological recordings in slices indicated MNTB synaptic alterations. In vivo multielectrode recordings showed that the overall level of MNTB activity was reduced in the L9′T. The present results indicate that the transient cochlear efferent innervation to inner hair cells during the critical period before the onset of hearing is involved in the refinement of topographic maps as well as in setting the properties of synaptic transmission at a central auditory nucleus. SIGNIFICANCE STATEMENT Cochlear inner hair cells of altricial mammals display spontaneous electrical activity before hearing onset. The pattern and firing rate of these cells are crucial for the correct maturation of the central auditory pathway. A descending efferent innervation from the CNS contacts the hair cells during this developmental window. The present work shows that genetic enhancement of efferent function disrupts the orderly topographic distribution of biophysical and synaptic properties in the auditory brainstem and causes severe synaptic dysfunction. This work adds to the notion that the transient efferent innervation to the cochlea is necessary for the correct establishment of the central auditory circuitry.
Power-Angle Modulation Controller to Support Transient Stability of Power Systems Dominated by Power Electronic Interfaced Wind Generation

During the last few years, electric power systems have undergone a widespread shift from conventional fossil-based generation toward renewable energy-based generation. Variable speed wind generators utilizing full-scale power electronics converters are becoming the preferred technology among other types of renewable-based generation, due to the high flexibility to implement different control functions that can support the stabilization of electrical power systems. This paper presents a fundamental study on the enhancement of transient stability in electrical power systems with increasing high share (i.e., above 50%) of power electronic interfaced generation. The wind generator type IV is taken as a representative form of power electronic interfaced generation, and the goal is to investigate how to mitigate the magnitude of the first swing while enhancing the damping of rotor angle oscillations triggered by major electrical disturbances. To perform such mitigation, this paper proposes a power-angle modulation (PAM) controller to adjust the post-fault active power response of the wind generator type IV, after a large disturbance occurs in the system. Based on a small size system, the PAM concept is introduced. The study is performed upon time-domain simulations and analytical formulations of the power transfer equations. Additionally, the IEEE 9 BUS system and the test model of Great Britain’s system are used to further investigate the performance of the PAM controller in a multi-machine context, as well as to perform a comparative assessment of the effect of different fault locations, and the necessary wind generators that should be equipped with PAM controllers.

Food habits of the Cougar Puma concolor (Carnivora: Felidae) in the Central Andes of the Colombian Coffee Region

The feeding habits of the cougar have been scarcely studied in Colombia, despite its importance in the ecosystems it inhabits. In this study, we analysed the diet of the cougar using 53 feces samples collected from several sites in the Central Andes of Colombia’s Coffee Growing Region. To identify prey species, we examined and compared bone fragments and hairs found in each sample with descriptions published in relevant literature and with specimens from the Natural History Museum of the Universidad de Caldas, Colombia. We found that rabbits (Sylvilagus sp.) provided half of the relative biomass consumed by the cougar (50%). Other preys identified belong to representatives of medium and large mammals such as marsupials (Didelphis: 10%), sloths (Choloepus: 9%), rodents (Coendou: 10%, Cuniculus: 9%), and deer (Mazama: 9%). Of the preys, Coendou rufescens has not, to our knowledge, been previously included in cougar diet literature. The curve of accumulation of species indicated that the number of samples obtained in this work fully describe the diet of this feline. Neither domestic species were recorded in this work, nor were there any relationships between the dry or rainy seasons and the consumption of prey species. The comparison of the information reported in this study and others carried out in the Andes may indicate the general nature of this feline’s diet and its adaptability to the prey species found in each area, since these vary in each one of them. It is probable that the obtained trophic niche value (0.33) is due to the abundance of rabbits present in the study area. It is also probable that the cougar has not consumed domestic species since, although it is close to cattle ranches, it has enough of wild prey in the area to supply its needs. The results of this study may help to improve our understanding of the feeding habits of this predator and its interaction with other species in this important region of Colombia. This will, in turn, promote major comprehension of the role of cougars in the Colombian Cordilleras and lead actions for their conservation.
of Birmingham Comparative study of solid oxide fuel cell coupled absorption refrigeration system for green and sustainable refrigerated transportation

: A vapour absorption refrigeration system (VARS) coupled with a solid oxide fuel cell (SOFC) is proposed for different types of refrigerated trucks (large, medium and small) as a favourable alternative to conventional diesel engine driven vapour compression refrigeration systems. An SOFC-supported VARS has the novel attributes of negligible environmental impact and the ability to keep the refrigeration system running while the vehicle engine is switched off, In addition, the SOFC system produces electricity which can be utilised for other operations on the vehicle. This in turn reduces the load on the main diesel engine of the vehicle. This research paper presents a comprehensive thermo-economic study for two different SOFC system configurations namely; series and parallel to optimise the SOFC sub-system layout. Moreover, a benefit function to optimise the SOFC stack size and operating conditions has been identified considering four performance parameters, namely; thermodynamic efficiency, weight of the system, greenhouse gas (GHG) emissions, and cost of cogeneration. The analysis was conducted on various categories of refrigerated trucks. The results show that a parallel configuration has an enhanced thermo-economic performance and requires a 45-65% lower number of SOFC cells to obtain the required refrigeration load in comparison to the series configuration. Simulation results indicated that the proposed SOFC-VARS for large, medium and small refrigerated trucks can output 3.3 kW, 12.8 kW and 18.7 kW of electric power and 1 kW, 4 kW and 6 kW of refrigeration power respectively. It was also found that the SOFC-coupled VARS is able to cater to the required refrigeration load with negligible emissions of GHGs and zero emissions of particulate matter and NOx compared to other refrigerated transportation technologies.

Atoms in strong light-fields: photon antibunching in single atom fluorescence

Some general remarks and suggestions concerning photon antibunching in single atom fluorescence are presented. The close connection between this antibunching effect and the ‘ reduction of the wave packet ’ due to the detection process is made explicit. It is pointed out that polarization effects could considerably change the shape of the signals. A dressed atom approach to these problems reveals analogies with quantum beats and suggests the use of frequency filters at the detection, selecting one component of the fluorescence spectrum and leading to new types of photon correlation signals.
Alkali Pretreatment and Enzyme Hydrolysis to Enhance the Digestibility of Rice Straw Cellulose for Microbial Oil Production

The alkali and alkali ethanolysis were used for pretreatment and delignification of rice straw. The combined hydrothermal- alkali method presented the high efficiency for removing the lignin. The pretreatment condition was optimized and achieved the highest of delignification (92.5%) under 30% (w/v) NaOH at a ratio of rice straw to alkali solution of 1 : 10 (w/v) at 121°C for 20 min. The highest yield of the remaining cellulose was 81.5% (w/w). The enzymatic hydrolysis of the rice straw cellulose was optimized for enhancement the digestibility via Response Surface Methodology (RSM). The cellulase activity, buffer solution, and hydrolysis time were evaluated. The optimum condition was cellulase activity at 935.18 U, 10 mL of buffer solution 10% (w/v) with hydrolysis time for 120 h, represented the maximum sugar yield with 136.6 g/L (0.54 g/g rice straw). The rice straw hydrolysate was further used as carbon source for microbial oil production by oleaginous yeasts.
Structural Analysis of Lexical-Bundles in Uncontrolled Environment of Spoken Discourse : The Same Heritage Language Groups*

This study explores the lexical bundles in the speech of Korean English language users who share the same heritage language and culture, Korean, but with different proficiency in English: Korean-Americans whose first language is English (2nd-generation Korean-Americans; G2KAs), bilingual Korean-Americans who started to learn English at an early age (1.5-generation Korean-Americans; G1.5KAs), and Koreans who learned English in Korea (L2Ks). One of the big differences between native (NSs) and non-native speakers (NNSs) is that NNSs use verb-related lexical bundles dominantly unlike NSs. Thus, the structural patterns of lexical bundle uses in addition to verb uses were examined. The results were consistent to previous studies showing increasing use of lexical bundles with increase in English proficiency; NSs (G2KAs) used the lexical bundles more than G1.5KAs and L2Ks. However, in contrast to previous studies, G2KAs mostly used VP-related lexical bundles, G1.5KAs used lexical bundles in the widest range, and L2Ks used the most lexical verbs. The paper elaborates the details of the results and suggests further studies including the new group of English users, G1.5KAs, to help understand a possible influence of their heritage language and culture on English speaking.
From Troublemakers to Pobrecitos: Honoring the Complexities of Survivorship of Latino Youth in a Suburban High School

ABSTRACT Despite the recognition to improve the schooling experiences of Latino youth, they continue to be targets of control. While much of the research on Latino youth takes place in urban schools, this qualitative, interview-based study examines the experiences of three Latino youth who attend a suburban high school in the Midwest. Latino youth in suburbia are not only subject to disciplinary measures that fuel their disconnection with school but must also wrestle with being told that they are not taking advantage of their school’s resources. This different sort of policing around resources problematically holds Latino youth accountable for their supposed “shortcomings. ” This project considers what Latino youth’s experiences can teach schools about how to enact asset-driven responses that empower rather than marginalize them.
