Digital Dividend: Potentia ls and Limitations of Mobile Broadband Access

Zusammenfassung: Diese Arbeit zeigt Potenziale und Grenzen heutiger und kunftiger Mobilfunksysteme zur flachendeckenden Versorgung mit breitbandigen Datenzugangen auf. Der Fokus liegt dabei auf der aktuellen Version (Release 8) des UMTS-LTE-Mobilfunk-Standards mit je einer Sende- und Empfangsantenne. Es wird gezeigt, dass dieser bei Nutzung von 20 MHz Frequenzbandbreite und mit den gegebenen Parametern zu Kanalkodierung und Modulation einem einzelnen Nutzer Spitzennutzerraten zwischen 2,8 Mbit/s am Zellrand und ca. 80 Mbit/s in der Nahe der Sendeantenne zur Verfugung stellen kann. Der durchschnittliche Zelldurchsatz gemittelt uber gleichmasig uber die Flache der Funkzelle verteilte Nutzer betragt bis zu 39 Mbit/s. Diese Werte skalieren linear mit der zur Verfugung stehenden Frequenzbandbreite. Durch Mehr-Antennensysteme und intelligente Interferenz-Managementalgorithmen lassen sich diese Werte noch steigern. Mithilfe der abgeleiteten Grenzen lasst sich zeigen, dass theoretische kapazitatserreichende Systeme mit 4 × 4-Antennenkonfiguration und idealer Interferenzausloschung durchschnittliche Zelldurchsatze > 1 Gbit/s erreichen konnen. Summary: This work highlights potentials and limitations of current and future mobile radio systems for area-wide mobile broadband access. The focus is on the current Release 8 of the UMTS LTE mobile radio standard implemented as single-antenna system. It is shown that, for the given parameters, user peak rates between 2.8 Mbit/s at the cell edge and approx. 80 Mbit/s near the base station can be achieved by single users utilizing 20 MHz frequency bandwidth. The average cell goodput of an arbitrary number of uniformly distributed users in a radio cell reaches up to 39 Mbit/s. These figures scale linearly with the available frequency bandwidth and can be increased using multiple-antenna systems and intelligent interference management algorithms. With the derived bounds it is shown that theoretical capacity achieving4×4 multiple-antenna systems with ideal interference cancellation could achieve an average cell goodput > 1 Gbit/s.
Active Flow Control on a UCAV Planform Using Synthetic Jets

This paper deals with experimental investigation of active flow control via synthetic jets using an unmanned combat air vehicle (UCAV) planform. Fourteen arrays of synthetic jets, mounted along both leading edges, were fully or partially activated to increase aerodynamic efficiency and reduce pitch-up moment. The measurements were carried out using a six-component external balance, a pressure scanner, and tuft flow visualization. It was observed that aerodynamic efficiency (L/D) and pitching moment were clearly affected by the location of jets. In particular, inboard and outboard actuation could effectively increase L/D. Moreover, inboard actuation showed a reduction in the pitch-up, even more than that generated by the full actuation. These results suggest that inboard actuation not only effectively increases L/D but also reduces the pitch-up using only a few actuators.
Effects of Natural Ageing on Mechanical Properties of PVDF-Coated Fabrics

Abstract This paper investigates the effects of natural ageing on the properties of a polyvinylidene fluoride PVDF-coated fabric, Ferrari 1302T, taken from the Qingdao Etsong Stadium. Contrast experiments between ageing and newly coated fabrics were carried out in terms of coating, uniaxial force at failure, tearing strength, Young’s modulus and bonding strength. Results show that the aged coating on the sunny side has several cracks, with bulges and pulverization, and the coating on the shaded side has some bulges, but there are no cracks and pulverization. Brightness decreases at different degrees on the sunny side and the shaded side. Force at failure and tearing strength also decrease. Degradation of tearing strength was found to be more obvious. Non-linear behaviour of coated fabrics under tensile tests can be described by using a piecewise linear relation and experiments show that both the uniaxial Young’s modulus and biaxial Young’s modulus of ageing Ferrari 1302T fabric decrease. Bonding strength of ageing fabrics decreases, but the failure mode indicates that the bonding still meets the required conditions.

“Treat me like a fellow human”: how young adults who blog about self-harm describe positive encounters with health care workers

Abstract Self-harm is a major problem among young adults, and many do not seek help from health care services. Little is known about how patients who harm themselves experience positive encounters with health care workers. Blogs are a way of communicating personal experiences to a broader public and may provide an immediate expression of such experiences. We conducted a thematic analysis of blog entries written by ten patients who carry out self-harm, in order to answer the question: How do young adults who blog about their self-harming describe positive encounters with health care workers? The analysis revealed four meta-themes: 1) I feel cared for, 2) I am treated like a fellow human, 3) I can talk about everything, and 4) I feel that the helper takes charge. Emotion regulation skills emerged as the most valued specific therapeutic ingredient. These findings are relevant for making young adults who self-harm feel understood and cared for.

A global drought dataset of standardized moisture anomaly index incorporating snow dynamics (SZI<sub>snow</sub>) and its application in identifying large-scale drought events

Abstract. Drought indices are hard to balance in terms of versatility (effectiveness for multiple types of drought), flexibility of timescales, and inclusivity (to what extent they include all physical processes). A lack of consistent source data increases the difficulty of quantifying drought. Here, we present a global monthly drought dataset with a spatial resolution of 0.25∘ from 1948 to 2010 based on a multitype and multiscalar drought index, the standardized moisture anomaly index incorporating snow dynamics (SZIsnow), driven by systematic fields from an advanced data assimilation system. The proposed SZIsnow dataset includes different physical water–energy processes, especially snow processes. Our evaluation of the dataset demonstrates its ability to distinguish different types of drought across different timescales. Our assessment also indicates that the dataset adequately captures droughts across different spatial scales. The consideration of snow processes improved the capability of SZIsnow, and the improvement is particularly evident over snow-covered high-latitude (e.g., Arctic region) and high-altitude areas (e.g., Tibetan Plateau). We found that 59.66 % of Earth's land area exhibited a drying trend between 1948 and 2010, and the remaining 40.34 % exhibited a wetting trend. Our results also indicate that the SZIsnow dataset can be employed to capture the large-scale drought events that occurred across the world. Our analysis shows there were 525 drought events with an area larger than 500 000 km2 globally during the study period, of which 68.38 % had a duration longer than 6 months. Therefore, this new drought dataset is well suited to monitoring, assessing, and characterizing drought and can serve as a valuable resource for future drought studies. The database is available at http://doi.org/10.5281/zenodo.5627369 (Wu et al., 2021).

Offline tourism: digital and screen ambivalence in Norwegian mountain huts with no internet access

ABSTRACT Digitalisation is a major transformative factor in tourism, yet studies show that holidaymakers are ambivalent about smartphone and Internet use. This study explores screen and digital ambivalence in nature-based tourism in and around the huts and routes of the Norwegian Trekking Association. While digital ambivalence describes ambiguous sentiments over being constantly connected, screen ambivalence covers mixed feelings regarding the presence of smartphones and screens. Methodologically, this qualitative study combined observations at 3 offline sites with an analysis of 30 field dialogues. The study found that hikers were highly aware of the positive and negative functions of digital media. Offline tourism may intensify the experience of taking a break, realising what tourists perceive to be the true nature of friluftsliv [outdoor life], heighten the sense of adventure and self-reliance. However, tensions concerning safety, missing social communication, and obstacles to posting on social media were also evident. This study contributes to the limited research on digital disconnection and offers new insights into the experiential qualities of offline holidays. Few studies have mapped tourist experiences in specific offline sites, and this study contributes to nature-based tourism research by showing how local norms mitigate tensions and nudge hikers towards positive interpretations of being digital-free.
Conventional Soybean Meal as Fishmeal Alternative in Diets of Japanese Seabass (Lateolabrax japonicus): Effects of Functional Additives on Growth, Immunity, Antioxidant Capacity and Disease Resistance

Aiming to optimize soymeal-based diets for Japanese seabass (Lateolabrax japonicas), a 105-day feeding trial was conducted to evaluate the effects of functional additives, including antioxidants (ethoxyquin, thymol and carvacrol) and chelated trace elements (Cu, Mn and Zn), on the growth, immunity, antioxidant capacity and disease resistance of fish fed diets with conventional soybean meal replacing 50% of fishmeal. Three isonitrogenous (45%) and isolipidic (11%) diets were formulated: (1) standard reference diet (FM, 42% fishmeal); (2) soymeal-based diet (SBM, 21% fishmeal and 30% conventional soybean meal); (3) SBM diet supplemented 0.0665% functional additives (FAS). Each experimental diet was randomly fed to quadruplicate groups of forty feed-trained Japanese seabass (initial average body weight = 125.6 ± 0.6 g) stocked in a saltwater floating cage. Upon the conclusion of the feeding trial, lower feed intake was observed in fish fed SBM compared to those fed FM and FAS. Fish fed FM showed the highest growth performance, estimated as the weight gain rate. Notably, FAS supported faster growth of fish than those fed SBM, indicating the optimal growth performance of dietary functional additives. The feed conversion rate showed the opposite trend among dietary treatments, with the highest value in fish fed SBM. Regarding immunity, fish fed soymeal-based diets suppressed the serum alternative complement pathway activities compared to FM, whereas the respiratory burst activity in macrophages of head kidneys showed a similar picture, but no statistical differences were observed. Further, fish fed soymeal-based diets had lower serum Cu-Zn SOD, CAT and GPx activities as well as liver vitamin E levels and scavenging rates of hydroxyl radical but higher liver MDA contents compared to the FM-fed group. Fish fed FAS had higher serum Cu-Zn SOD and GPx activities and liver vitamin E levels than those fed SBM, suggesting the enhancement of antioxidant capacity of dietary functional additives. For the disease resistance against Vibrio harveyi infection, fish fed SBM had the highest cumulative mortality, followed by the FAS and FM groups. Additionally, the biomarkers related to the immune and antioxidant capacities had a positive correlation with the relative abundance of Paracoccus and Pseudomonas, while liver MDA levels had a negative correlation with the relative abundance of Pseudomonas and Psychrobacter. Collectively, soymeal replacing 50% of fishmeal suppressed the growth, immunity, antioxidant capacity and disease resistance of Japanese seabass, while dietary supplementation of antioxidants and chelated trace elements could mitigate soymeal-induced adverse effects on growth and disease resistance through the improvement in antioxidant capacity and regulation of gut microbiota.
Multi-Strain and -Species Investigation of Volatile Metabolites Emitted from Planktonic and Biofilm Candida Cultures

Candida parapsiliosis is a prevalent neonatal pathogen that attains its virulence through its strain-specific ability to form biofilms. The use of volatilomics, the profiling of volatile metabolites from microbes is a non-invasive, simple way to identify and classify microbes; it has shown great potential for pathogen identification. Although C. parapsiliosis is one of the most common clinical fungal pathogens, its volatilome has never been characterised. In this study, planktonic volatilomes of ten clinical strains of C. parapsilosis were analysed, along with a single strain of Candida albicans. Headspace-solid-phase microextraction coupled with gas chromatography-mass spectrometry were employed to analyse the samples. Species-, strain-, and media- influences on the fungal volatilomes were investigated. Twenty-four unique metabolites from the examined Candida spp. (22 from C. albicans; 18 from C. parapsilosis) were included in this study. Chemical classes detected across the samples included alcohols, fatty acid esters, acetates, thiols, sesquiterpenes, and nitrogen-containing compounds. C. albicans volatilomes were most clearly discriminated from C. parapsilosis based on the detection of unique sesquiterpene compounds. The effect of biofilm formation on the C. parapsilosis volatilomes was investigated for the first time by comparing volatilomes of a biofilm-positive strain and a biofilm-negative strain over time (0–48 h) using a novel sampling approach. Volatilomic shifts in the profiles of alcohols, ketones, acids, and acetates were observed specifically in the biofilm-forming samples and attributed to biofilm maturation. This study highlights species-specificity of Candida volatilomes, and also marks the clinical potential for volatilomics for non-invasively detecting fungal pathogens. Additionally, the range of biofilm-specificity across microbial volatilomes is potentially far-reaching, and therefore characterising these volatilomic changes in pathogenic fungal and bacterial biofilms could lead to novel opportunities for detecting severe infections early.
Measuring Knowledge with Patent Data: an Application to Low Carbon Energy Technologies

We estimate a latent factor model (LFM) to compute an index that measures the quality of an extensive data set of inventions related to Low Carbon Energy Technologies (LCETs) and patented by seven countries during 1980-2010. We use the quality index to compute the stock of knowledge accumulated in the fifteen analyzed LCETs. We investigate the composition of the stock of knowledge and find that important substitutions between technologies have taken place: technologies such as solar thermal and nuclear have been progressively replaced by wind power, solar photovoltaic and to a less extent by few other technologies. This substitution effect can be decomposed into quantity (the number of inventions) and quality (the quality of inventions). Investigating the latter, the quality of nuclear-related inventions has decreased whereas it has increased for solar photovoltaic (PV), wind power and energy storage inventions. Few newer technologies, i.e. hydrogen and sea energy, also show signs of an increase of their average quality of inventions over the last years of the data set. We go further and investigate the inventions distribution in terms of quality and conclude that the potential for signifcant inventions related to nuclear technology has decreased over time whereas higher levels of quality have been reached in newer technological areas. A cross-country comparison is conducted to assess the innovation performance of the seven countries covered by our study. We conclude that technology policies are less efficient when demand-pull and supply-push approaches are not coupled.
Testing mechanisms for weight support distribution during inverted quadrupedalism in primates.

A key characteristic of primate above-branch arboreal locomotion is hindlimb-biased weight support, subverting the typical mammalian condition in which the majority of the body weight is supported by the forelimb. This shift is thought to reflect an adaptation toward the arboreal niches exploited by early primates. However, above-branch quadrupedalism represents only one locomotor mode employed by primates in arboreal contexts. Inverted quadrupedal gaits, in which primates are suspended beneath branches by their hands and feet, have been documented in more than 50 primate taxa. This gait is characterized by a return to forelimb-biased weight distributions and a transition from peak vertical forces being greatest in the hindlimb to being greatest in the forelimb, which may occur to protect the hindlimb from high magnitudes of tensile loading when inverted. In this study, we compare kinetic and kinematic data during upright and inverted quadrupedalism in Lemur catta, Varecia variegata, Cebus capucinus, and Saimiri sciureus. These data are referenced against a classical inverted quadrupedal model: the two-toed sloth (Choloepus didactylus). Our findings show that inverted quadrupedalism in primates is differentiated from above-branch quadrupedalism by increases in forelimb weight support, forelimb contact times, and both forelimb and hindlimb joint excursions. Previously postulated biomechanical models outlining mechanisms relating to the control of weight support during upright walking do not translate well to inverted quadrupedal walking. We suggest that inverted primates may simply be adopting basal neuromuscular gait characteristics and applying them facultatively to this infrequent locomotor behavior.
The Development and Validation Prospective Mathematics Teachers Holistic Assessment Tools

This study aims to explain the stages of developing a Holistic assessment instrument for the competence of prospective mathematics teachers based on constructs from several literature reviews to measure the competence/ability of prospective mathematics teachers. This development goes through 8 steps of developing non-test instruments. Validity and reliability of instrument traced from 101 students. The initial instrument design carries out initially, then validated with the Aiken formula by 14 experts. The series of initial stages obtained 30 instruments ready to be tested from the original 40 items. The second stage is to perform a confirmatory factor analysis (EFA) followed by testing the construct and convergent validity and looking for the reliability coefficient with confirmatory factor analysis (CFA). The results of the EFA produced 28 items become into four factors, namely pedagogic content knowledge, mathematical content knowledge, positive behavior and respect, teacher enthusiasm (passion). The results of the CFA indicate that the constructs built have construct validity in the good category, convergent validity fulfilled because all AVE values are more than the minimum limit (0.5). Internal reliability (Cronbach's Alpha) = 0.96, Composite Reliability (CR) is in the range 0.88-0.92, and Average Variance Extracted (AVE) is in the range 0.55-0.58. The results of the CFA produced 27 items. Based on the measurement, it can say that the instrument of Holistic Assessment of Prospective Mathematics Teachers is suitable for use at the research.
