description: Over the course of our lifetimes, we accumulate extensive experience associating the things that we see with the words we have learned to describe them. As a result, adults engaged in a visual search task will often look at items with labels that share phonological features with the target object, demonstrating that language can become activated even in non-linguistic contexts. This highly interactive cognitive system is the culmination of our linguistic and visual experiences—and yet, our understanding of how the relationship between language and vision develops remains limited. The present study explores the developmental trajectory of language-mediated visual search by examining whether children can be distracted by linguistic competitors during a non-linguistic visual search task. Though less robust compared to what has been previously observed with adults, we find evidence of phonological competition in children as young as 8 years old. Furthermore, the extent of language activation is predicted by individual differences in linguistic, visual, and domain-general cognitive abilities, with the greatest phonological competition observed among children with strong language abilities combined with weaker visual memory and inhibitory control. We propose that linguistic expertise is fundamental to the development of language-mediated visual search, but that the rate and degree of automatic language activation depends on interactions among a broader network of cognitive abilities.Other Information Published in: Cognitive Research: Principles and Implications

description: We prove that statistical information theoretic quantities, such as information entropy, cannot generally be interrelated with the lower limit of energy dissipation during information erasure. We also point out that, in deterministic and error-free computers, the information entropy of memories does not change during erasure because its value is always zero. On the other hand, for information-theoretic erasure - i.e., "thermalization" / randomization of the memory - the originally zero information entropy (with deterministic data in the memory) changes after erasure to its maximum value, 1 bit / memory bit, while the energy dissipation is still positive, even at parameters for which the thermodynamic entropy within the memory cell does not change. Information entropy does not convert to thermodynamic entropy and to the related energy dissipation; they are quantities of different physical nature. Possible specific observations (if any) indicating convertibility are at most fortuitous and due to the disregard of additional processes that are present.

description: Using wave optics approach, we have studied the light-trapping ability of a combination of grating and distributed-Bragg-reflectors (GDBR) in the rear face of a conventional thick, flat solar cell. We have analyzed structures that not only can provide reflectivity close to 100%, but that can also increase the path-length enhancement of internal confined rays for a certain wavelength range. Thus, the amount of energy absorbed in the active layer of the cell can also be increased.

description: We study the effect of the white rear sheet located around photocells in photovoltaic modules. This white sheet reflects part of the incident light back to the photocell by means of internal reflections, thus increasing the production of electrical current with a low additional cost. We have developed a software program that simulates a simple module with once cell in order to obtain the improvement of electrical current production as a function of the width of the white strip surrounding the cell. We find that the wider the white sheet around the photocell, the greater the increase of electrical current generated in it. These results will help to the optimization of the design of solar panels. We obtain a good agreement when comparing our simulation results with measurements carried out in a real prototype.
Introduction of the Kifilideen's Extermination and Determinant of Matrix (KEDM)  Method for Resolving Multivariable Linear Systems with Two, Three and Four Unknowns
Creators: name: Osanyinpeju, Kifilideen
Publisher: name: Zenodo

description: The Gaussian extermination technique poses significant challenges when applied to systems of linear equations with three or four unknowns, as it involves multiple steps and requires a high number of arithmetic operations, making the method less efficient and more complex to implement and understand. Furthermore, the Jacobian and Gauss-Seidel methods produce approximate solutions that may not accurately represent the true solution. Additionally, LU decomposition method can introduce round – off errors, leading to inaccurate solutions. The graphical method is also impractical for systems with more than two unknowns, as visualization and interpretation become increasingly difficult. Cramer’s rule, used for resolving large systems of linear equations, is computationally complex and inefficient due to complexity of determinant calculations. Therefore, a simpler and more efficient technique is needed for resolving linear systems of simultaneous equations with two, three, and four unknowns. This study introducesKifilideen’s Extermination and Determinant of Matrix (KEDM) Method for resolving multivariable linear systems with two, three, and four unknowns. The KEDM method employs a progressive extermination technique to narrow down the number of unknowns of a system of simultaneous equations using a determinant of matrix layout. This method was developed to efficiently determine the solution of linear systems of simultaneous equations. The KEDMmethod was tested on linear systems of simultaneous equations with two, three and four unknowns to evaluate its effectiveness and simplicity. The results show that the KEDM methodinvolves only 2 × 2 determinant of matrix calculations, making it simpler, easier, more intuitive, less computationally expensive and more efficient to implement and understand.

description: Background This article presents examples of how to utilize the research output, to initiate academia-industry interaction, with the ultimate task of launching a new product: a smart heart valve prosthesis for pediatric patients. The article summarizes our efforts in a way that may also be informative to researchers working in fields other than medical devices development. Our task is not to provide a step-by-step guide, but rather to create inspiration, also by describing differences in expectations of business and academic entities. Methods We analyzed market reports, surveyed the scientific literature and conducted interviews with the key players in the field of medical devices. We also obtained a feedback from clinicians, academia and industry-related researchers, technology transfer centres, representatives of public organization and the creators of legislation. Results We have obtained and reported the definitive answers that together constitute a critical review of strategies that should be used by researchers who seek to commercialize the outputs of their research. Conclusion As a result of our investigation, we discovered that the commercialization of research is a complex process, which in some critical aspects does not depend solely on the researcher himself. The most promising ideas, supported by strong experimental evidence, can simply be overlooked by industry representatives, without the proper support of institutions such as a technology transfer centre. Besides, the involvement of scientists in a business project takes them, at least temporarily, outside the regular academic environment, which may cause discomfort and pose a risk to the career path. The limitation to be addressed is the reluctance to report the unsuccessful attempts, which should be considered a legitimate educational experience that ultimately leads to improvement.Other Information Published in: Translational Medicine Communications

description: This sheet deals with detection of generation and behavior of microplasma in solar cell. The generation of microplasma is influenced by several factors. The first of them is defected silicon crystal-grid causing nonhomogeneity
of parameters that, in turn, creates visible defect. The second is dislocation of PN junction. At places where junction is thinner or mechanically damaged, the microplasma discharge and emission of light is present. Another sign of observed microplasma is noise, which has random spectrum in frequency range. Microplasma noise is measurable even before the creation of light emissions. That provides a way to obtain information about microplasma creation with exiguous reverse voltage. Voltage needed for observation of microplasma highly depends on solar cell area and reverse voltage. The whole process is observed with a special CCD camera in a dark special cryogenic box. CCD camera G2-3200 with low noise Kodak chip KAF-3200ME is used for measuring.
Description of electromagnetic and favored $α$-transitions in heavy odd-mass nuclei

description: We describe electromagnetic and favored α-transitions to rotational bands in odd-mass nuclei built upon a single particle state with angular momentum projection $Ω=\frac{1}{2}$ in the region $88 \le Z \le 98$. We use the particle coupled to an even-even core approach described by the Coherent State Model (CSM) and the coupled channels method to estimate partial $α$-decay widths. We reproduce the energy levels of the rotational band where favored $α$-transitions occur for 26 nuclei and predict B (E2) values for electromagnetic transitions to the bandhead using a deformation parameter and a Hamiltonian strength parameter for each nucleus, together with an effective collective charge depending linearly on the deformation parameter. Where experimental data is available, the contribution of the single particle effective charge to the total B (E2) value is calculated. The Hamiltonian describing the $α$- nucleus interaction contains two terms, a spherically symmetric potential given by the double-folding of the M3Y nucleon-nucleon interaction plus a repulsive core simulating the Pauli principle and a quadrupole-quadrupole (QQ) interaction. The $α$-decaying state is identified as a narrow outgoing resonance in this potential. The intensity of the transition to the first excited state is reproduced by the QQ coupling strength. It depends linearly both on the nuclear deformation and the square of the reduced width for the decay to the bandhead, respectively. Predicted intensities for transitions to higher excited states are in a reasonable agreement with experimental data. This formalism offers a unified description of energy levels, electromagnetic and favored $α$-transitions for known heavy odd-mass $α$-emitters.

description: How do product designers apply photovoltaic solar technology in consumer products? Photovoltaic (PV) solar energy powered consumer products can play an important role in enhancing the diffusion of PV solar energy application in general, creating awareness and providing access to energy in both developed and developing countries. The design of PV powered products is however, still immature. In this paper six design projects are
analysed for the application of guidelines from the Delft Design Approach. This is a generic design approach for the design of renewable energy powered products, based on a phase model for product design, the Energy Matching Model and a Design for Sustainability benchmark. In the analysis, the design processes of the projects are mapped on the basic cycle of product design. Thereby insight is created in the tools applied and how design choices were made. That question is addressed in this paper. Six design projects were analysed for the application of guidelines from the Delft Design Approach. This is a generic design approach for the design of renewable energy powered products, based on a phase model for product design, the Energy Matching Model and a Design for Sustainability benchmark. The analysis indicates that structural application of the guidelines facilitates the design process, and makes it more transparent. Further research and development for the Delft Design Approach is desirable in order to improve the development of PV powered products.

description: In modern-day medicine, nanotechnology and nanoparticles are some of the indispensable tools in disease monitoring and therapy. The term “nanomaterials” describes materials with nanoscale dimensions (< 100 nm) and are broadly classified into natural and synthetic nanomaterials. However, “engineered” nanomaterials have received significant attention due to their versatility. Although enormous strides have been made in research and development in the field of nanotechnology, it is often confusing for beginners to make an informed choice regarding the nanocarrier system and its potential applications. Hence, in this review, we have endeavored to briefly explain the most commonly used nanomaterials, their core properties and how surface functionalization would facilitate competent delivery of drugs or therapeutic molecules. Similarly, the suitability of carbon-based nanomaterials like CNT and QD has been discussed for targeted drug delivery and siRNA therapy. One of the biggest challenges in the formulation of drug delivery systems is fulfilling targeted/specific drug delivery, controlling drug release and preventing opsonization. Thus, a different mechanism of drug targeting, the role of suitable drug-laden nanocarrier fabrication and methods to augment drug solubility and bioavailability are discussed. Additionally, different routes of nanocarrier administration are discussed to provide greater understanding of the biological and other barriers and their impact on drug transport. The overall aim of this article is to facilitate straightforward perception of nanocarrier design, routes of various nanoparticle administration and the challenges associated with each drug delivery method.Other Information Published in: Biomaterials Research

description: The assessment of PV devices is a key issue at development and production level. The latest generation of Pasan solar simulators, based on Xenon single flash lamps, demonstrates one of the best uniformities and stabilities available today on the market. A new step has been achieved with advanced control of the spectrum: Pasan has developed custom-made interferential filters for optimal AM1.5 spectral matching. Resulting spectra are assessed with a customised spectrometer, designed for precise measurement of such a flasher. Results show that the spectrum of Pasan simulators (based on flash tubes with high current density plus interferential filters) demonstrates a spectral match of ± 12.5 %. Combined with already achieved high level of uniformity (< 1%) and stability (< 1%), the performances of Pasan solar simulators are two times better than IEC class AAA specifications. Moreover, the spectral content is very stable throughout the 10 ms pulse, as well as during the whole lifetime of the flash tubes, and remains well within class A tolerances for irradiance ± 30% around the nominal level. Such a tight control of the spectral match is a key factor to reduce spectral mismatch errors and leads to high accuracy IV-measurements, particularly crucial for thin-film or multijunction devices.

description: The analysis of the early star formation history (SFH) of nearby galaxies, obtained from their resolved stellar populations is relevant as a test for cosmological models. However, the early time resolution of observationally derived SFHs is limited by several factors. Thus, direct comparison of observationally derived SFHs with those derived from theoretical models of galaxy formation is potentially biased. Here we investigate and quantify this effect. For this purpose, we analyze the duration of the early star formation activity in a sample of four Local Group dwarf galaxies and test whether they are consistent with being true fossils of the pre-reionization era; i.e., if the quenching of their star formation occurred before cosmic reionization by UV photons was completed. Two classical dSph (Cetus and Tucana) and two dTrans (LGS-3 and Phoenix) isolated galaxies with total stellar masses between $1.3\times 10^6$ to $7.2\times 10^6$ M$_\odot$ have been studied. Accounting for time resolution effects, the SFHs peak as much as 1.25 Gyr earlier than the optimal solutions. Thus, this effect is important for a proper comparison of model and observed SFHs. It is also shown that none of the analyzed galaxies can be considered a true-fossil of the pre-reionization era, although it is possible that the {\it outer regions} of Cetus and Tucana are consistent with quenching by reionization.

description: This paper treats heterojunction solar cells where the energy conversion efficiency is limited by interface recombination due to incomplete absorber inversion. We discuss cases of incomplete absorber inversion due to: (1) voltage drop in the emitter, (2) negative conduction band offset and (3) Fermi level pinning. The aim is to discriminate these cases by the activation energy, Ea, of the saturation current density, J0. We calculate Ea from Shockley-Read-Hall theory for the 3 cases. Voltage drop in the emitter (1) is characterised by Ea=Eg,a where Eg,a is the band gap of the absorber. A negative conduction band offset (2) shows up as Ea=Eg,i where Eg,i is the band gap at the interface. Case (3) of Fermi level pinning can be diagnosed by Ea=bp,0 where bp,0 is the pinning position of the Fermi level at the interface. Thus, if the experimental value of Ea is smaller than Eg,a, it does not only indicate that the cell is in the limit of interface recombination but it also rules out case (1) as the source for interface recombination. On the other hand, if Ea equals Eg,a, interface recombination may still limit the diode current. A fact that is often overlooked.

description: A systematic investigation of octupole deformed nuclei is presented for even-even systems with $Z\leq 106$ located between the two-proton and two-neutron drip lines. For this study we use five most up-to-date covariant energy density functionals of different types, with a non-linear meson coupling, with density dependent meson couplings, and with density-dependent zero-range interactions. Pairing correlations are treated within relativistic Hartree-Bogoliubov (RHB) theory based on an effective separable particle-particle interaction of finite range. This allows us to assess theoretical uncertainties within the present covariant models for the prediction of physical observables relevant for octupole deformed nuclei. In addition, a detailed comparison with the predictions of non-relativistic models is performed. A new region of octupole deformation, centered around $Z\sim 98, N\sim 196$ is predicted for the first time. In terms of its size in the $(Z,N)$ plane and the impact of octupole deformation on binding energies this region is similar to the best known region of octupole deformed nuclei centered at $Z\sim 90, N\sim 136$. For the later island of octupole deformed nuclei, the calculations suggest substantial increase of its size as compared with available experimental data.

description: Background Monitoring athletes’ external load during a soccer match may be useful to predict post-match acute and residual fatigue. This estimation would allow individual adjustments to training programs to minimize injury risk, improve well-being, and restore players’ physical performance and inform the recovery process. Methods Using a systematic review and meta-analysis of the literature, the aim is to determine which monitoring variables would be the strongest predictors of acute (immediately) and residual (up to 72 h) fatigue states in soccer. PubMed, SPORTDiscus, and Web of Science databases were searched (until September 2018). Studies concurrently examining soccer match-related external load metrics and subjective and/or objective measures were selected to determine pooled correlations ($$ \overline{r} $$r¯) with confidence intervals (CI). The quality and strength of the findings of each study were evaluated to identify overall levels of evidence. Results Eleven studies were included (n = 165 athletes). Acute ($$ \overline{r} $$r¯ = 0.67; 95% CI = [0.40, 0.94]) and residual (24 h post-match, $$ \overline{r} $$r¯ = 0.54; 95% CI = [0.35, 0.65]) changes in muscle damage markers and countermovement jump peak power output (CMJPPO) were, with moderate to strong evidence, largely correlated with running distance above 5.5 m s−1. No other external load metric was largely correlated with both biochemical and neuromuscular markers. For every 100-m run above 5.5 m·s−1, CK activity measured 24 h post-match increased by 30% and CMJPPO decreased by 0.5%. Conversely, the total distance covered did not present any evidence of a clear relationship with any fatigue-related marker at any time-point. Conclusions Running distance above 5.5 m·s−1 represents the most sensitive monitoring variable characterizing biochemical and neuromuscular responses, at least when assessed during the initial 24 h (not at 48 h/72 h) post-match recovery period. In addition, total distance covered is not sensitive enough to inform decision-making during the fatigue monitoring process.Other Information Published in: Sports Medicine - Open

description: We propose a Self-supervised Anomaly Detection technique, called SeMAnD, to detect geometric anomalies in Multimodal geospatial datasets. Geospatial data comprises of acquired and derived heterogeneous data modalities that we transform to semantically meaningful, image-like tensors to address the challenges of representation, alignment, and fusion of multimodal data. SeMAnD is comprised of (i) a simple data augmentation strategy, called RandPolyAugment, capable of generating diverse augmentations of vector geometries, and (ii) a self-supervised training objective with three components that incentivize learning representations of multimodal data that are discriminative to local changes in one modality which are not corroborated by the other modalities. Detecting local defects is crucial for geospatial anomaly detection where even small anomalies (e.g., shifted, incorrectly connected, malformed, or missing polygonal vector geometries like roads, buildings, landcover, etc.) are detrimental to the experience and safety of users of geospatial applications like mapping, routing, search, and recommendation systems. Our empirical study on test sets of different types of real-world geometric geospatial anomalies across 3 diverse geographical regions demonstrates that SeMAnD is able to detect real-world defects and outperforms domain-agnostic anomaly detection strategies by 4.8-19.7% as measured using anomaly classification AUC. We also show that model performance increases (i) up to 20.4% as the number of input modalities increase and (ii) up to 22.9% as the diversity and strength of training data augmentations increase.

description: Grid independency, silent electrical energy generation without emissions, harmless low-DC-power, mobility and new materials with new aesthetics are key characteristics of photovoltaic technologies. Combined with new scientific tropes that are emerging in this highly vibrating multidisciplinary field of photovoltaics, they have attracted a first generation of 'early adapters' in the arts. It allows them further dynamic exploration of the complex relation between light, electrical energy and the media that can be used to represent it. Their practices and works bring to life -in their turn- new artistic tropes originating from unexpected set ups, combinations of materials and contexts of use that might lead to new scientific questions that might benefit the improvement of the PV-technologies. moreover, in an era in which the ways of organizing the access to energy have to be reshaped, it is important that the worlds of the arts play an active role in the crucial debate.

description: Exercise frequency is important for maintaining health; however, its effects on postprandial responses remain largely unknown. Better understanding this during popular sports activities such as football may influence exercise habits. Therefore, the aim of the present study was to examine the effects of playing one single versus three consecutive days of 60-min small-sided football matches on postprandial lipemia. Fifteen males performed either one (1FOOT; n = 7) or three 60-min football (3FOOT; n = 8) sessions across an 8-day trial period. On day 1, a blood sample was collected at fasted (0 min) and 0.75, 2, 4, 6 h after a high-fat meal. Participants were then randomly allocated to the 1FOOT (day 7) or 3FOOT (days 5, 6, 7) condition. On day 8, they repeated the high-fat meal and blood sampling for 6 h following the meal. Postprandial total and incremental area under the curve (AUC, iAUC, respectively) were calculated. The postprandial triglyceride iAUC was 41% lower from pre- to post-measures for the 1FOOT (p < 0.05; ES = 1.02) and 15.7% lower for the 3FOOT (ns; ES = 0.41). Total triglyceride AUC was lower (26%) post-football matches in the 3FOOT group only (p < 0.01; ES = 1.23). In 3FOOT, insulin concentration was lower for post- compared to pre-measures at 0.75 and 2 h, respectively (p < 0.001). One single 60-min small-sided football match lowered postprandial TG incremental area under the curve while performing three consecutive days of football matches did not result in a greater attenuation.

description: Purpose We aimed to assess the utility of shock index (SI) to predict the need for massive transfusion protocol (MTP) in patients with solid organ injury (SOI) in a Level 1 Trauma center. Methods We conducted a retrospective analysis for patients with SOI between 2011 and 2014. Patients were categorized according to on-admission SI into low (< 0.8) and high SI (≥0.8) group. Results A total of 4500 patients were admitted with trauma, of them 572 sustained SOIs (289 patients had SI ≥0.8). In comparison to low SI, patients with high SI were younger, had higher injury severity scores (ISS) and lower Trauma and Injury Severity Score (TRISS); (p < 0.001). The proportion of exploratory laparotomy (EXLap), blood transfusion (BT), MTP activation, sepsis and hospital mortality were significantly higher in patients with high SI. Serum lactate (r = 0.34), hematocrit (r = − 0.34), ABC score (r = 0.62), ISS (r = 0.35), and amount of transfused blood (r = 0.22) were significantly correlated with SI. On multivariable regression analysis using 9 relevant variables (age, sex, ISS, ED GCS, serum lactate, hematocrit, Abdomen AIS and Focused assessment with sonography in trauma (FAST) and SI), SI ≥ 0.8 was an independent predictor of BT (OR 2.80; 95%CI 1.56–4.95) and MTP (OR 2.81;95% CI 1.09–7.21) . Conclusions In patients with SOI, SI is a simple bedside predictor for BT and MTP activation. Further prospective studies are needed to support our findings.Other Information Published in: Injury Epidemiology

description: We report on recent results showing that the geometric phase can be used as a tool in the analysis of many different physical systems, as mixed boson systems, CPT and CP violations, Unruh effects and thermal states. We show that the geometric phases appearing in the time evolution of mixed meson systems like $B_{s}^{0}-\bar{B}_{s}^{0}$ and the $K^{0}-\bar{K}^{0}$ are linked to the parameter $z$ describing the $CPT$ violation. A non zero phase difference between particle and antiparticle arises only in the presence of $CPT$ symmetry breaking. Then the geometric phase can represent a completely new test for the $CPT$ invariance. Moreover, we study the geometric phase of systems represented by mixed state and undergoing a nonunitary evolution and propose the realization of interferometers which can prove the existence of the Unruh effect and can allow very precise measurements of temperature. We are glad to dedicate this paper to Professor Gaetano Vilasi in the occasion of his 70th birthday.

description: Elastic pion-nucleon scattering is analyzed in the framework of chiral perturbation theory up to fourth order within the heavy-baryon expansion and a covariant approach based on an extended on-mass-shell renormalization scheme. We discuss in detail the renormalization of the various low-energy constants and provide explicit expressions for the relevant $β$-functions and the finite subtractions of the power-counting breaking terms within the covariant formulation. To estimate the theoretical uncertainty from the truncation of the chiral expansion, we employ an approach which has been successfully applied in the most recent analysis of the nuclear forces. This allows us to reliably extract the relevant low-energy constants from the available scattering data at low energy. The obtained results provide a clear evidence that the breakdown scale of the chiral expansion for this reaction is related to the $Δ$-resonance. The explicit inclusion of the leading contributions of the $Δ$-isobar is demonstrated to substantially increase the range of applicability of the effective field theory. The resulting predictions for the phase shifts are in an excellent agreement with the ones from the recent Roy-Steiner-equation analysis of pion-nucleon scattering.

description: Using the China Spallation Neutron Source (CSNS) linac as the injector, a 500 MeV proton synchrotron is proposed for multidisciplinary application, such as biology, material and proton therapy. The synchrotron will deliver proton beam with energy from 80 MeV to 500 MeV. A compact lattice design was worked out, and all the important beam dynamics issues were investigated. The 80 MeV H- beam is stripped and injected into the synchrotron by using multi-turn injection. In order to continuously extraction the proton with small beam loss, the achromatic structure is proposed and slow extraction method with RF knock-out is adopted and optimized.

description: Thermodynamics provides a powerful tool for estimating ultimate efficiency limits of photovoltaic and photochemical energy conversion. This paper presents a thermodynamic analysis of the photo-generated voltage based on a rigorous treatment of the energy and entropy fluxes which allow for the quantised nature of the interaction between radiation and matter. It is shown that the voltage V produced by the solar cell is equal to the energy of the incident solar photon multiplied by the appropriate Carnot factor, less irreversible losses. The various losses are associated with entropy generation through kinetic losses, photon cooling and étendue expansion of the incident beam. Simple expressions for the voltage are obtained using an approximation where the energy and entropy changes are modelled by the corresponding expressions for a two-dimensional ideal photon gas. We show that this method also provides an indication how solar cell efficiency can be increased by making use of the free carrier heat generated in the cell upon photo-excitation.

description: Detection and removal of outliers in a dataset is a fundamental preprocessing task without which the analysis of the data can be misleading. Furthermore, the existence of anomalies in the data can heavily degrade the performance of machine learning algorithms. In order to detect the anomalies in a dataset in an unsupervised manner, some novel statistical techniques are proposed in this paper. The proposed techniques are based on statistical methods considering data compactness and other properties. The newly proposed ideas are found efficient in terms of performance, ease of implementation, and computational complexity. Furthermore, two proposed techniques presented in this paper use transformation of data to a unidimensional distance space to detect the outliers, so irrespective of the data’s high dimensions, the techniques remain computationally inexpensive and feasible. Comprehensive performance analysis of the proposed anomaly detection schemes is presented in the paper, and the newly proposed schemes are found better than the state-of-the-art methods when tested on several benchmark datasets.Other Information Published in: Journal of Big Data

description: Neighbor discovery is a fundamental service for initialization and managing network dynamics in wireless sensor networks and mobile sensing applications. In this paper, we present a novel design principle named Talk More Listen Less (TMLL) to reduce idle-listening in neighbor discovery protocols by learning the fact that more beacons lead to fewer wakeups. We propose an extended neighbor discovery model for analyzing wakeup schedules in which beacons are not necessarily placed in the wakeup slots. Furthermore, we are the first to consider channel occupancy rate in discovery protocols by introducing a new metric to trade off among duty-cycle, latency and channel occupancy rate. Guided by the TMLL principle, we have designed Nihao, a family of energy-efficient asynchronous neighbor discovery protocols for symmetric and asymmetric cases. We compared Nihao with existing state of the art protocols via analysis and real-world testbed experiments. The result shows that Nihao significantly outperforms the others both in theory and practice.

description: There is an immediate need to identify alternative sources of high-nutrient feedstocks for domestic livestock production and poultry, not only to support growing food demands but also to produce microalgae-source functional foods with multiple health benefits. Various species of microalgae and cyanobacteria are used to supplement existing feedstocks. In this review, microalgae have been defined as a potential feedstock for domestic animals due to their abundance of proteins, carbohydrates, lipids, minerals, vitamins, and other high-value products. Additionally, the positive physiological effects on products of animals fed with microalgal biomass have been compiled and recommendations are listed to enhance the assimilation of biomolecules in ruminant and nonruminant animals, which possess differing digestive systems. Furthermore, the role of microalgae as prebiotics is also discussed. With regards to large scale cultivation of microalgae for use as feed, many economic trade-offs must be considered such as the selection of strains with desired nutritional properties, cultivation systems, and steps for downstream processing. These factors are highlighted with further investigations needed to reduce the overall costs of cultivation. Finally, this review outlines the pros and cons of utilizing microalgae as a supplementary feedstock for poultry and cattle, existing cultivation strategies, and the economics of large-scale microalgal production.Other Information Published in: Journal of Animal Science and Biotechnology

description: We simulate the conception parameters of a model of a silicon multilayer solar cell. The cell is composed by four layers of opposite conductivities forming three junctions inside the cell. The electric contacts are tailored vertically to collect the minority carrier generated under illumination. We developed the equations giving the output power, the fill factor and the efficiency of the cell, taking into account the series resistances of each layer. We optimized, using Matlab software, the thicknesses of the layers, the impurity concentration level and the distance between the electric contacts. We showed that the optimized photovoltaic structure, with the silicon properties published at the Ioffe institute
website, gives an efficiency of 20.66 %. The n-p-n-p silicon cell deliver a short circuit current Icc = 45.3 mA/cm², an open circuit voltage Voc = 0.746 V and an output power of 28.5 mW/cm². The corresponding fill factor is FF = 84.29 %.
