A Survey on Application Specific Processor Architectures for Digital Hearing Aids
Authors: Gerlach Lukas , Payá-Vayá Guillermo , Blume Holger 
Published: March 2021

AbstractOn the one hand, processors for hearing aids are highly specialized for audio processing, on the other hand they have to meet challenging hardware restrictions. This paper aims to provide an overview of the requirements, architectures, and implementations of these processors. Special attention is given to the increasingly common application-specific instruction-set processors (ASIPs). The main focus of this paper lies on hardware-related aspects such as the processor architecture, the interfaces, the application specific integrated circuit (ASIC) technology, and the operating conditions. The different hearing aid implementations are compared in terms of power consumption, silicon area, and computing performance for the algorithms used. Challenges for the design of future hearing aid processors are discussed based on current trends and developments.
On the Possibility of Presentism with Occurrents
Authors: Marabello Marco 
Published: March 2021

AbstractThis paper defends the possibility of admitting occurrents in a presentist ontology. Two ways of doing so are proposed, the first one involves Meinongian presentism. By using the notion of non-existent object and coherently modifying some mereological principle, it is argued, the presentist can allow for occurrents. The second proposal involves ex-concrete objects. Ex-concrete objects, i.e. objects that are contingently not concrete, have been used by Linsky and Zalta (Philosophical Perspectives, 8(Logic and Language), 431-458, 1994), Williamson (2002) in the modal metaphysics debate, by Orilia (Philosophical Studies, 173(3), 589-607, 2016) in the presentism-eternalism debate, and by Longenecker (Synthese 195(11), 5091-5111, 2018) in the debate about material constitution. I argue that, just by admitting ex-concrete objects, it is possible to have occurrents even for the presentist. Of course, in order to do so we must modify our definitions of occurrent and continuant. Nevertheless, I argue that my theory is metaphysically sound, at least for the presentist persuaded by the intuitive claim that there are occurrents, which otherwise she must reject.
Effects of ontogenetic stage and leaf age on leaf functional traits and the relationships between traits in Pinus koraiensis

Published: March 2021

AbstractInvestigating the effects of ontogenetic stage and leaf age on leaf traits is important for understanding the utilization and distribution of resources in the process of plant growth. However, few studies have been conducted to show how traits and trait-trait relationships change across a range of ontogenetic stage and leaf age for evergreen coniferous species. We divided 67Pinus koraiensisSieb. et Zucc. of various sizes (0.3–100 cm diameter at breast height, DBH) into four ontogenetic stages, i.e., young trees, middle-aged trees, mature trees and over-mature trees, and measured the leaf mass per area (LMA), leaf dry matter content (LDMC), and mass-based leaf nitrogen content (N) and phosphorus content (P) of each leaf age group for each sampled tree. One-way analysis of variance (ANOVA) was used to describe the variation in leaf traits by ontogenetic stage and leaf age. The standardized major axis method was used to explore the effects of ontogenetic stage and leaf age on trait-trait relationships. We found that LMA and LDMC increased significantly and N and P decreased significantly with increases in the ontogenetic stage and leaf age. Most trait-trait relationships were consistent with the leaf economic spectrum (LES) at a global scale. Among them, leaf N content and LDMC showed a significant negative correlation, leaf N and P contents showed a significant positive correlation, and the absolute value of the slopes of the trait-trait relationships showed a gradually increasing trend with an increasing ontogenetic stage. LMA and LDMC showed a significant positive correlation, and the slopes of the trait-trait relationships showed a gradually decreasing trend with leaf age. Additionally, there were no significant relationships between leaf N content and LMA in most groups, which is contrary to the expectation of the LES. Overall, in the early ontogenetic stages and leaf ages, the leaf traits tend to be related to a "low investment-quick returns" resource strategy. In contrast, in the late ontogenetic stages and leaf ages, they tend to be related to a "high investment-slow returns" resource strategy. Our results reflect the optimal allocation of resources inPinus koraiensisaccording to its functional needs during tree and leaf ontogeny.
Exogenous application of growth stimulators improves the condition of maize exposed to soil drought
Authors: Ostrowska Agnieszka , Grzesiak Maciej T. , Hura Tomasz 
Published: March 2021

AbstractSoil drought is a major problem in plant cultivation. This is particularly true for thermophilic plants, such as maize, which grow in areas often affected by precipitation shortage. The problem may be alleviated using plant growth and development stimulators. Therefore, the aim of the study was to analyze the effects of 5-aminolevulinic acid (5-ALA), zearalenone (ZEN), triacontanol (TRIA) and silicon (Si) on water management and photosynthetic activity of maize under soil drought. The experiments covered three developmental stages: three leaves, stem elongation and heading. The impact of these substances applied during drought stress depended on the plant development stage. 5-ALA affected chlorophyll levels, gas exchange and photochemical activity of PSII. Similar effects were observed for ZEN, which additionally induced stem elongation and limited dehydration. Beneficial effects of TRIA were visible at the stage of three leaves and involved leaf hydration and plant growth. A silicon preparation applied at the same developmental stage triggered similar effects and additionally induced changes in chlorophyll levels. All the stimulators significantly affected transpiration intensity at the heading stage.

Published: March 2021

AbstractAtrial fibrillation (AF), the commonest sustained cardiac arrhythmia affecting the adult population, is often casually discovered among hospitalized people. AF onset is indeed triggered by several clinical conditions such as acute inflammatory states, infections, and electrolyte disturbance, frequently occurring during the hospitalization. We aimed to evaluate whether systematic AF screening, performed through an automated oscillometric blood pressure (BP) device (Microlife WatchBP Office AFIB, Microlife AG, Switzerland), is effective for detecting AF episodes in subjects admitted to an Internal Medicine ward. 163 patients consecutively hospitalized at the Unit of Internal Medicine of the “Santa Maria” Terni University Hospital between November 2019 and January 2020 (mean age ± standard deviation: 77 ± 14 years, men proportion: 40%) were examined. Simultaneously with BP measurement and AF screening, a standard 12-lead electrocardiogram (ECG) was performed in all subjects. AF was diagnosed by ECG in 29 patients (18%). AF screening showed overall 86% sensitivity and 96% specificity. False negatives (n = 4) had RR-interval coefficient of variation lower than true positives (n = 25, p < 0.01), suggesting a regular ventricular rhythm during AF. The repeated evaluation substantially confirmed the same level of agreement. AF screening was positive in all patients with new-onset AF (n = 6, 100%). Systematic AF screening in patients admitted to Internal Medicine wards, performed using the Microlife WatchBP Office AFIB, is feasible and effective. The opportunity to implement such technology in daily routine clinical practice to prevent undiagnosed AF episodes in hospitalized patients should be the subject of further research.
Employees, Advisees, and Emerging Scholars: A Qualitative Analysis of Graduate Students' Roles and Experiences of Sexual Violence and Sexual Harassment on College Campuses
Authors: Bloom Brittnie E. , Sorin Cierra Raine , Wagman Jennifer A. , Oaks Laury 
Published: March 2021

AbstractSexual violence and sexual harassment (SVSH) are pervasive across university campuses. SVSH research rarely focuses on graduate students, who occupy unique positions within university settings due to their multiple responsibilities (e.g., teaching, research, mentoring), including managing unequal power dynamics with mentors and advisors. As part of a larger qualitative study, we sought to better understand SVSH generally and, when applicable, experiences of SVSH among graduate students on three campuses. Our primary research questions were: (a) How graduate students understand SVSH on their campus and whether they are at risk, (b) How graduate students navigate power dynamics that position them to experience SVSH, and (c) What graduate student-centered solutions and improvements can make campuses safer, more equitable spaces for all students. To answer these questions, we conducted 21 in-depth interviews and 8 focus group discussions with a diverse group of graduate students across various graduate programs. Using grounded theory and implementing student-centered approaches to data collection and analysis, we identified multiple themes, including graduate students’ uncertainty regarding SVSH on campus; and how power relations with faculty, combined with distrust of university processes, keep many graduate students silent about SVSH. Finally, employing graduate students’ suggestions, we offer recommendations for how universities can improve campus climate and SVSH resources for graduate students.
Typical emotional expression in children’s drawings of the human face
Authors: Cannoni Eleonora , Pinto Giuliana , Bombi Anna Silvia 
Published: March 2021

AbstractThis study was aimed at verifying if children introduce emotional expressions in their drawings of human faces, and if a preferential expression exists; we also wanted to verify if children’s pictorial choices change with increasing age. To this end we examined the human figure drawings made by 160 boys and 160 girls, equally divided in 4 age groups: 6–7; 8–9; 10–11; 12–13 years; mean ages (SD in parentheses) were: 83,30 (6,54); 106,14 (7,16) 130,49 (8,26); 155,40 (6,66). Drawings were collected with the Draw-a-Man test instructions, i.e. without mentioning an emotional characterization. In the light of data from previous studies of emotion drawing on request, and the literature about preferred emotional expressions, we expected that an emotion would be portrayed even by the younger participants, and that the preferred emotion would be happiness. We also expected that with the improving ability to keep into account both mouth and eyes appearance, other expressions would be found besides the smiling face. Data were submitted to non-parametric tests to compare the frequencies of expressions (absolute and by age) and the frequencies of visual cues (absolute and by age and expressions). The results confirmed that only a small number of faces were expressionless, and that the most frequent emotion was happiness. However, with increasing age this representation gave way to a variety of basic emotions (sadness, fear, anger, surprise), whose representation may depend from the ability to modify the shapes of both eyes and mouth and changing communicative aims of the child.
Anonymous birth: Biographical knowledge and dyadic coping in adoptive mothers and fathers

Published: March 2021

AbstractResearch on adoptive parents of anonymously born children is still scarce. Open issues are (1) examining how much biographical information is available to adoptive parents, (2) considering differences between adoptive mothers and fathers, and (3) understanding what affects their dyadic coping. Hence, this study set out to compare adoptive mothers’ and fathers’ mental health, attachment styles, dyadic coping, and biographical knowledge, and to identify predictors of dyadic coping. 62 mothers and 40 fathers (mean age: 46 years) raising an anonymously born adoptee answered online or paper-pencil versions of the Brief Symptom Inventory, Vulnerable Attachment Style Questionnaire, Dyadic Coping Inventory, Child Behavior Checklist, and a checklist of biographical data. Descriptive analyses showed that biographical knowledge was generally low in adoptive parents. More information was available on the birth mother than the birth father, with letters being the most common memorial. Furthermore, student t-tests revealed few differences: adoptive mothers reported to be more anxious and rated their ability to communicate stress and common dyadic coping as higher than did adoptive fathers. Finally, a hierarchical linear regression identified knowledge of more biographical data, parents’ older age as well as child’s younger age and higher psychopathology scores as predictors of better adoptive parents’ dyadic coping. These findings highlight the difficult task of gathering biographical information whilst maintaining the birth mother’s anonymity. They also stress the need of further research which may inform policies tailored to the specific needs of adoptive parents in the context of anonymous birth.
Why Doesn't the Decriminalisation of Same-Sex Sexuality and Sex Work Ensure Rights? The Legality and Social Acceptance of Transgressive Sexualities in Urban Mozambique
Authors: Aantjes Carolien J. , Munguambe Khátia , Muchanga Vasco , Capurchande Rehana , Poku Nana K. 
Published: March 2021

Abstract
Background
The dependence on the law to direct people’s behaviour is known for its imperfections, yet it has become a mainstream response to social problems in modern day society. It is also the pathway through which internationally-recognised rights obligations, including sexual rights, are anticipated to diffuse across distinctly different societies. We studied the introduction of new legal standards in Mozambique, with an interest in their ability to promote the rights of lesbian, gay, bisexual, transgender, intersex (LGBTI) people and sex workers.

Methods
Between 2019 and 2020, we conducted sixteen key informant interviews with jurists, policymakers, and civil society advocates at national level and seventy-eight interviews with opinion leaders from local communities in three urban sites situated across Northern, Central, and Southern Mozambique.

Results
The new legal standards, in which same-sex sexuality and sex work are no longer criminalised, found little resonance with intersecting religious, sexual, gender, and socio-cultural norms. Whilst there was a consensus not to discriminate, sensitisation and rehabilitation of LGBTI people and sex workers were considered imperative. This stance, coupled with a continued presence of ambiguous language in and incongruences between legislative pieces, attenuates the country’s commitment to internationally recognised rights obligations.

Conclusions
In a context of weak civilian awareness and support, the legal reforms are not likely to make a profound positive impact on the lives of LGBTI people and sex workers. Policy action should extend beyond health and law enforcement institutions and draw in community leaders to mediate the social processes that undercut the universality of rights.
Evaluation of water quality and eutrophication status of Hawassa Lake based on different water quality indices
Authors: Menberu Zemed , Mogesse Beshah , Reddythota Daniel 
Published: March 2021

AbstractLake Hawassa is one of the major Ethiopian Rift Valley Lakes having an endorheic basin system. The surrounding community makes use of the lake water for the multiple purposes of irrigation, domestic water supply, recreation and fish harvesting. The aim of the present study was to ascertain the water quality of the lake in terms of water quality indices (WQI) and its health over a period of three months covering both dry and wet seasons. Overall, the water quality of Lake was unfit and bad as per the weighted arithmetic method (120.06–228.29) and modified Bascarón water quality index (MBWQI) methods (26.81–33.89), respectively. However, the quality was indicated as marginal, as per the Canadian Council of Ministers of the Environment (CCME) water quality index method (44.2–51.1). On average, the lake was under the hypertrophic stage as per the standard based on the results of Secchi depth and nutrient concentration. The current study showed the lake being unfit for all-purposes as per WAWQI range (> 100). According to the physicochemical and biological parameters, of the lake, it requires mitigation measures to control Eutrophication and pollutants inflow.

Published: March 2021

Abstract
Background
This paper aims to investigate the occurrence and removal characteristics of phthalate esters from bottled drinking water using silver modified roasted date pits. Three adsorbents, namely roasted date pits (RODP), silver-modified roasted date pits (S-RODP), and activated carbon (AC) were used to investigate their adsorption characterizations in removing dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), butyl benzyl phthalate (BBP), di-2-ethylhexyl phthalate (DEHP), and di-n-octyl phthalate (DNOP) from the collected bottle water samples.

Methods
The occurrences of the phthalate esters in the collected bottled water samples were carried out at different temperatures (30, 50, and 60 °C), and analyzed using gas chromatography-mass spectrometry analysis - selected ion monitoring. Batch adsorption isotherms were used to study and establish the efficiency of such adsorbents in removing phthalate esters, in which they describe the adsorbent-adsorbate interaction systems. Adsorption efficiency of the various adsorbents was investigated by using different adsorbent masses (0.05 g, 0.10 g, and 0.15 g) and temperature (30 °C, 50 °C, and 60 °C). Different physical and chemical characterizations were studied using scanning electron microscopy (SEM), Fourier transform infrared (FTIR), Brunauer-Emmett-Teller (BET) surface area, pore radius, and pore volume.

Results
The results indicated that the most abundant phthalate esters were DMP followed by DEP under 30 °C; however, DNOP was not detected in any of the tested water samples, except for one sample under 30 °C with a concentration of 0.031 μg/mL. The obtained results showed that phthalate esters leaching to the bottled drinking water were affected by storage temperature. The phthalate esters levels were increased with increasing the temperature to 60 °C. It was concluded that the ability of S-RODP for the adsorption of phthalate esters was better than the removal percentage obtained by AC and RODP. The removal percentage was increased from 90 to 99% by increasing the temperature from 30 to 50 °C and then decreased to 92.3% at 60 °C.

Conclusion
RODP was successfully used as an effective adsorbent for phthalate esters removal from drinking water. However, S-RODP has the highest removal abilities than other adsorbents due to the newly formed functional groups on its surface.
Selective network discovery via deep reinforcement learning on embedded spaces
Authors: Morales Peter , Caceres Rajmonda Sulo , Eliassi-Rad Tina 
Published: March 2021

AbstractComplex networks are often either too large for full exploration, partially accessible, or partially observed. Downstream learning tasks on these incomplete networks can produce low quality results. In addition, reducing the incompleteness of the network can be costly and nontrivial. As a result, network discovery algorithms optimized for specific downstream learning tasks given resource collection constraints are of great interest. In this paper, we formulate the task-specific network discovery problem as a sequential decision-making problem. Our downstream task is selective harvesting, the optimal collection of vertices with a particular attribute. We propose a framework, called network actor critic (NAC), which learns a policy and notion of future reward in an offline setting via a deep reinforcement learning algorithm. The NAC paradigm utilizes a task-specific network embedding to reduce the state space complexity. A detailed comparative analysis of popular network embeddings is presented with respect to their role in supporting offline planning. Furthermore, a quantitative study is presented on various synthetic and real benchmarks using NAC and several baselines. We show that offline models of reward and network discovery policies lead to significantly improved performance when compared to competitive online discovery algorithms. Finally, we outline learning regimes where planning is critical in addressing sparse and changing reward signals.
Neural Concomitants of Remote Memory in a Comedian with Exceptional Verbal Memory
Authors: Mella Nathalie , Grouiller Frédéric , Mouthon Michael , Picard Fabienne 
Published: March 2021

AbstractMost studies exploring how remote memory is represented in the brain are based on strong episodic self-related components. Because of methodological reasons, much less is known about how the information concerning the semantic part of autobiographical memory is retrieved, and whether the brain correlates differ according to the autobiographical moment of the memory formation. In the present study, we explored the neural concomitants of the retrieval of texts learnt at different periods of life, in a comedian with exceptional verbal memory skills. This 49-year-old comedian was instructed to recite aloud a total of 30 texts he learnt during three different epochs: before the age of 15 years (E1), between the age of 15 and 25 years (E2), and after the age of 25 years (E3). The most salient activation was observed for memory from the farthest period, with a preponderance of the medial rostral prefrontal cortex (PFC) and of the precuneus. There was no hippocampal activation during text retrieval by comparison to a control condition, whatever the learning period. This study supports the assumption that the recall of remote semantic memories can occur without hippocampal activation. We discussed the activation of the rostral PFC during retrieval of the oldest (and best consolidated) memories as the possible involvement of control meta-memory processes rather than memory processes per se.
