DeeperThings: Fully Distributed CNN Inference on Resource-Constrained Edge Devices
Authors: Stahl Rafael , Hoffman Alexander , Mueller-Gritschneder Daniel , Gerstlauer Andreas , Schlichtmann Ulf 
Published: April 2021

AbstractPerforming inference of Convolutional Neural Networks (CNNs) on Internet of Things (IoT) edge devices ensures both privacy of input data and possible run time reductions when compared to a cloud solution. As most edge devices are memory- and compute-constrained, they cannot store and execute complex CNNs. Partitioning and distributing layer information across multiple edge devices to reduce the amount of computation and data on each device presents a solution to this problem. In this article, we propose DeeperThings, an approach that supports a full distribution of CNN inference tasks by partitioning fully-connected as well as both feature- and weight-intensive convolutional layers. Additionally, we jointly optimize memory, computation and communication demands. This is achieved using techniques to combine both feature and weight partitioning with a communication-aware layer fusion method, enabling holistic optimization across layers. For a given number of edge devices, the schemes are applied jointly using Integer Linear Programming (ILP) formulations to minimize data exchanged between devices, to optimize run times and to find the entire model’s minimal memory footprint. Experimental results from a real-world hardware setup running four different CNN models confirm that the scheme is able to evenly balance the memory footprint between devices. For six devices on 100 Mbit/s connections the integration of layer fusion additionally leads to a reduction of communication demands by up to 28.8%. This results in run time speed-up of the inference task by up to 1.52x compared to layer partitioning without fusing.
Risk Sharing in a Politically Divided Monetary Union
Authors: Parsley David , Popper Helen 
Published: April 2021

AbstractWe document stark asynchronicity across U.S. states, particularly across groups of states whose populations have voted consistently Democrat or consistently Republican in national elections; and we show that the risk-sharing channels of these groups of states differ substantially. However, we find that these groups of states–even swing states, where the role of fiscal flows is small (on par with Europe’s)–do share risk. Indeed, we halve previous estimates of states’ residual risk by using new data to account for sharing risk through changes in population, prices, and durable goods consumption. These findings indicate that political differences alone do not themselves preclude macroeconomic risk sharing within a monetary union.
Watermelon rinds as cost-efficient adsorbent for acridine orange: a response surface methodological approach

Published: April 2021

AbstractIn the current investigation, watermelon rinds (WMR) have been utilized as an eco-friendly and cost-efficient adsorbent for acridine orange (AO) from contaminated water samples. Adsorption of AO onto raw (RWM) and thermally treated rinds (TTWM250 and TTWM500) has been studied. The adsorption efficiency of the three adsorbents was evaluated by measuring the % removal (%R) of AO and the adsorption capacity (qe, mg/g). Dependent variables (%R and qe) were optimized as a function of four factors: pH, sorbent dosage (AD), the concentration of AO (DC), and contact time (ST). Box–Behnken (BB) design has been utilized to obtain the optimum adsorption conditions. Prepared adsorbents have been characterized using scanning electron microscopy (SEM), Fourier-transform infrared (FT-IR), and Raman spectroscopies. The surface area of RWM, TTWM250, and TTWM500, as per the Brunauer-Emmett-Teller (BET) analysis, was 2.66, 2.93, and 5.03 m2/g, respectively. Equilibrium investigations suggest that Freundlich model was perfectly fit for adsorption of AO onto TTWM500. Maximum adsorption capacity (qmax) of 69.44 mg/g was obtained using the Langmuir equation. Adsorption kinetics could be best described by the pseudo-second-order (PSO) model. The multi-cycle sorption-desorption study showed that TTWM500 could be regenerated with the adsorption efficiency being preserved up to 87% after six cycles.
Towards a Unitary Case for Russellian Panpsychism
Authors: Dondoni Luca 
Published: April 2021

AbstractOne of the most pressing challenges that occupy the Russellian panpsychist’s agenda is to come up with a way to reconcile the traditional argument from categorical properties (Seager Journal of Consciousness Studies, 13(10–11), 129–145, 2006; Alter & Nagasawa, 2015) with H. H. Mørch’s dispositionalism-friendly argument from the experience of causation (2014, Topoi, 39, 1073–1088, 2018, 2020) — on the way to a unitary, all-encompassing case for the view. In this regard, Mørch claims that, via the commitment to the Identity theory of properties, one can consistently hold both panpsychist arguments without contradiction (2020: 281) — I shall refer to such proposal as Reconciliation. In my paper, I shall argue that this is not the case. To this extent, I will first consider H. Taylor’s argument that the Identity theorists have the exact same resources as the dispositionalists (as, after careful enquiry, their views on the metaphysics of properties turn out to coincide (Philosophical Studies, 175, 1423–1440, 2018: 1438)), and thus contend that Reconciliation fails to obtain. Then, I will suggest that one can avoid the problem and reconcile the arguments by adopting a different version of the powerful qualities view, namely the Compound view — and thus advance a reformulated version of the claim, i.e. Reconciliation*. Finally, even though pursuing my proposed solution might expose Russellian panpsychism to the risk of epiphenomenalism, I shall conclude that such specific form of epiphenomenalism is a rather benign one, and thus that, via Reconciliation*, the constitution of a unitary case for panpsychism as a positive proposal (and not as a mere alternative to dualism and physicalism) can be achieved.
GABAergic Mechanisms Can Redress the Tilted Balance between Excitation and Inhibition in Damaged Spinal Networks

Published: April 2021

AbstractCorrect operation of neuronal networks depends on the interplay between synaptic excitation and inhibition processes leading to a dynamic state termed balanced network. In the spinal cord, balanced network activity is fundamental for the expression of locomotor patterns necessary for rhythmic activation of limb extensor and flexor muscles. After spinal cord lesion, paralysis ensues often followed by spasticity. These conditions imply that, below the damaged site, the state of balanced networks has been disrupted and that restoration might be attempted by modulating the excitability of sublesional spinal neurons. Because of the widespread expression of inhibitory GABAergic neurons in the spinal cord, their role in the early and late phases of spinal cord injury deserves full attention. Thus, an early surge in extracellular GABA might be involved in the onset of spinal shock while a relative deficit of GABAergic mechanisms may be a contributor to spasticity. We discuss the role of GABA A receptors at synaptic and extrasynaptic level to modulate network excitability and to offer a pharmacological target for symptom control. In particular, it is proposed that activation of GABA A receptors with synthetic GABA agonists may downregulate motoneuron hyperexcitability (due to enhanced persistent ionic currents) and, therefore, diminish spasticity. This approach might constitute a complementary strategy to regulate network excitability after injury so that reconstruction of damaged spinal networks with new materials or cell transplants might proceed more successfully.
Impact of a motorcycle on cyclist aerodynamic drag in parallel and staggered arrangements

Published: April 2021

AbstractCycling races contain a multitude of motorcycles for various activities including television broadcasting. During parts of the race, these motorcycles can ride in close proximity of cyclists. Earlier studies focused on the impact of a nearby motorcycle on cyclist drag for in-line arrangements. It was shown that not only a motorcycle in front of a cyclist but also a motorcycle closely behind a cyclist can substantially reduce cyclist drag. However, there appears to be no information in the scientific literature about the impact of the motorcycle on cyclist drag for parallel and staggered arrangements. This paper presents wind tunnel measurements of cyclist drag for 32 different parallel and staggered cyclist-motorcycle arrangements. It is shown that the parallel arrangement leads to a drag increase for the cyclist, in the range of 5 to about 10% for a lateral distance of 2 to 1 m. The staggered arrangement can lead to either a drag increase or a drag decrease, where the latter is about 2% for most positions analyzed. For one of the parallel arrangements, computational fluid dynamics simulations were performed to provide insight into the reasons for the drag increase. A cyclist power model was used to convert the drag changes into potential time gains or losses. Compared to a lone cyclist riding at a speed of 46.8 km/h (13 m/s) on level road in calm weather, the time loss by a drag increase of 10%, 4% and − 2% was 2.16, 0.76 s and − 0.80 s per km, respectively. These time differences are large enough to influence the outcome of cycling races.

AbstractBased on Morse theory for the energy functional on path spaces we develop a deformation theory for mapping spaces of spheres into orthogonal groups. This is used to show that these mapping spaces are weakly homotopy equivalent, in a stable range, to mapping spaces associated to orthogonal Clifford representations. Given an oriented Euclidean bundle $$V \rightarrow X$$

Published: April 2021

AbstractRecent meta-analyses and meta-analytic reviews of most common approaches to cognitive training broadly converge on describing a lack of transfer effects past the trained task. This also extends to the more recent attempts at using video games to improve cognitive abilities, bringing into question if they have any true effects on cognitive functioning at all. Despite this, video game training studies are slowly beginning to accumulate and provide evidence of replicable improvements. Our study aimed to train non-video game playing individuals in the real-time strategy video game StarCraft II in order to observe any subsequent changes to perceptual, attentional, and executive functioning. Thirty hours of StarCraft II training resulted in improvements to perceptual and attentional abilities, but not executive functioning. This pattern of results is in line with previous research on the more frequently investigated “action” video games. By splitting the StarCraft II training group into two conditions of “fixed” and “variable” training, we were also able to demonstrate that manipulating the video game environment produces measurable differences in the amount of cognitive improvement. Lastly, by extracting in-game behavior features from recordings of each participant’s gameplay, we were able to show a direct correlation between in-game behavior change and cognitive performance change after training. These findings highlight and support the growing trend of more finely detailed and methodologically rigorous approaches to studying the relationship between video games and cognitive functioning.
Photon attenuation parameters of non-essential amino acids using EPICS2017 library interpolations

Published: April 2021

AbstractMass attenuation coefficients, effective atomic numbers, electron densities and energy absorption and exposure buildup factors for the non-essential and conditionally non-essential amino acids including alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine have been acquired using the latest evaluated photoatomic library of EPICS2017. The library was used by constructing an interpolation script that calculates for all photon attenuation parameters. Comparisons were made using alternative Monte Carlo simulation results for 15 energy points from 59.5 to 1333 keV, and in contrast with experimental works in literature. Good agreements for the mass attenuation coefficients were observed between EPICS2017-based values compared with Monte Carlo code and experimental results. Similar trends for the effective atomic numbers and electron densities were observed from EPICS2017 interpolation and from results found in literature. Conversely, buildup factors acquired by Geometric-Progression fitting parameters were reported in this work preliminarily for most of these biomolecules at different penetration depths. Overall, cysteine showed the most significant deviation among the other non-essential amino acids due to the presence of sulfur in its molecular structure.
Thermal imaging based maximum power point tracking for solar modules in variable ambient temperature
Authors: Khan Irshad , Khan Shaheen 
Published: April 2021

AbstractIn this study, a thermography based modified perturb & observe maximum power point tracking (P&O MPPT) technique is proposed and implemented to overcome challenges due to unstable environmental temperature and radiance. A temperature based empirical model of PV module is used to approximate the peak power parameters. The objective of using temperature based model is to minimize the difference voltage (∆V) signal which in turn decreases the time to reach maximum power point and hence increases the speed of the MPPT system. Less number of iterations to achieve maximum power point also improves the output signal quality by reducing the number of fluctuations in the signal. Although the temperature based MPPT methods have already been suggested in literature but the novelty of the proposed method lies in using infrared (IR) images to monitor the instant temperature of photovoltaic (PV) module, which give its advantage in the form of fast and stable steady-state output. Results of the proposed scheme are found better when compared to the conventional P&O MPPT.

Published: April 2021

AbstractPorous carbons were prepared from the biomass waste rambutan peels using hydrothermal carbonization followed by the KOH activation process. Rambutan peel derived porous carbons (RPC) with high surface area of 2104 m2 g−1 and large pore volume of 1.2 cm3 g−1 were obtained at KOH/carbon ratio of 4 and activation temperature of 900 °C. The as-obtained porous carbons were capable of encapsulating sulfur with a high loading of 68.2 wt% to form RPC/S composite cathode for lithium sulfur (Li–S) battery. High specific discharge capacities of about 1275 mAh g−1 were demonstrated by the RPC/S composites at 0.1 C. After 200 cycles at 0.1 C, a high specific capacity of 936 mAh g−1 was maintained, showing an excellent capacity retention of about 73%.

AbstractBackgroundDietary interventions did not prevent depression onset nor reduced depressive symptoms in a large multi-center randomized controlled depression prevention study (MooDFOOD) involving overweight adults with subsyndromal depressive symptoms. We conducted follow-up analyses to investigate whether dietary interventions differ in their effects on depressive symptom profiles (mood/cognition; somatic; atypical, energy-related).MethodsBaseline, 3-, 6-, and 12-month follow-up data from MooDFOOD were used (n= 933). Participants received (1) placebo supplements, (2) food-related behavioral activation (F-BA) therapy with placebo supplements, (3) multi-nutrient supplements (omega-3 fatty acids and a multi-vitamin), or (4) F-BA therapy with multi-nutrient supplements. Depressive symptom profiles were based on the Inventory of Depressive Symptomatology.ResultsF-BA therapy was significantly associated with decreased severity of the somatic (B= −0.03,p= 0.014,d= −0.10) and energy-related (B= −0.08,p= 0.001,d= −0.13), but not with the mood/cognition symptom profile, whereas multi-nutrient supplementation was significantly associated with increased severity of the mood/cognition (B= 0.05,p= 0.022,d= 0.09) and the energy-related (B= 0.07,p= 0.002,d= 0.12) but not with the somatic symptom profile.ConclusionsDifferentiating depressive symptom profiles indicated that food-related behavioral interventions are most beneficial to alleviate somatic symptoms and symptoms of the atypical, energy-related profile linked to an immuno-metabolic form of depression, although effect sizes were small. Multi-nutrient supplements are not indicated to reduce depressive symptom profiles. These findings show that attention to clinical heterogeneity in depression is of importance when studying dietary interventions.
Whose Landscape Is It? Remapping Memory and History in Interwar Central Europe
Authors: Veszprémi Nóra 
Published: April 2021

AbstractAfter the collapse of the Habsburg Empire and the sanctioning of new national borders in 1920, the successor states faced the controversial task of reconceptualizing the idea of national territory. Images of historically significant landscapes played a crucial role in this process. Employing the concept of mental maps, this article explores how such images shaped the connections between place, memory, and landscape in Hungary and Czechoslovakia. Hungarian revisionist publications demonstrate how Hungarian nationalists visualized the organic integrity of “Greater Hungary,” while also implicitly adapting historical memory to the new geopolitical situation. As a counterpoint, images of the Váh region produced in interwar Czechoslovakia reveal how an opposing political agenda gave rise to a different imagery, while drawing on shared cultural traditions from the imperial past. Finally, the case study of Dévény/Devín/Theben shows how the idea of being positioned “between East and West” lived on in overlapping but politically opposed mental maps in the interwar period. By examining the cracks and continuities in the picturesque landscape tradition after 1918, the article offers new insight into the similarities and differences of nation-building processes from the perspective of visual culture.

SummaryThis study aimed to compare the expression of genes regulating follicles development, survival and steroid hormones secretion in oocytes and granulosa cells (GCs) and study the correlation between their expression and follicular fluid (FF) levels of progesterone (P4) in pregnant and non-pregnant camels. In total, 138 ovarian pairs from slaughtered camels were used. Gene expression and hormonal assay were determined using real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA), respectively. The obtained results revealed that the number of follicles (3–8 mm) was significantly (P < 0.05) lower in pregnant, compared with non-pregnant, camels. P4 level in the FF was significantly (P < 0.05) higher in pregnant, compared with non-pregnant, camels. However, no significant (P > 0.05) difference was noticed in the oestradiol (E2) level. STAR, PTEN, IGF1 and BCL2 mRNA levels were significantly higher in GCs and significantly lower in oocytes of pregnant, compared with non-pregnant, camels. However, follicle-stimulating hormone receptor (FSHR) mRNA level was significantly lower in GCs and oocytes, and the BMP15 mRNA level was significantly lower in oocytes of pregnant, compared with non-pregnant, camels. P4 level in FF was positively correlated with STAR, PTEN, IGF1 and BCL2 mRNA levels in GCs and negatively correlated with BMP15 mRNA levels in oocytes and FSHR mRNA levels in GCs and oocytes of pregnant camels. It could be concluded that pregnancy-induced variations in oocytes and GC expression of BMP15, IGF1, FSHR, STAR, BCL2, and PTEN genes might be associated with a decrease in the number of follicles and an increase in the FF level of P4.

Published: April 2021

AbstractStudying the mechanisms of interaction between rift segments is key to understanding the kinematics of plate boundaries in continental rifts. However, the spatial and temporal evolution of deformation at rift linkage zones is rarely observed directly. Here, we combine InSAR data spanning 2005–2010 and 2014–2019 from ENVISAT and Sentinel‐1 satellites, respectively, with local seismicity from the Afar rift to investigate the plate‐boundary kinematics of the Afrera linkage zone, the junction between the Erta Ale and Tat Ali magmatic segments in Northern Afar (Ethiopia). We obtain time‐series of cumulative InSAR Line‐Of‐Sight (LOS) displacements that show deformation is accommodated by a series of active en‐echelon faults striking ∼NS and characterized by normal slip associated with a left‐lateral strike‐slip component. Additionally, we observe spatial variation in fault behavior with stick‐slip and creep. The faults in the center of the linkage zone behave primarily in a stick‐slip mode (with abrupt fault displacements up to ∼40 mm) and fault motions are associated with earthquakes of ML > 5. Conversely, faults at the edge of the linkage zone, near the magmatic segments, show creep and some stick‐slip behavior (with cumulative LOS displacement up to ∼30–40 mm over a ∼5‐year period) accompanied by low‐level seismicity. Some of the creeping faults are also spatially associated with hydrothermal springs. We interpret that the temporal behavior of the faults in the linkage zone is controlled by the interplay between tectonic extension, high heat flows, and fluid circulation near the magmatic segments where creeping of some faults is favored.
