Software Engineering Research: The Need to Strengthen and Broaden the Classical Scientific Method

The classical scientific method has been settled through the last centuries as a cyclic, iterative process of observation, hypothesis formulation, and confirmation/refutation of hypothesis through experimentation. This “experimental scientific method” was mainly developed in the context of natural sciences dealing with the physical world, such as Mechanics, Thermodynamics, Electromagnetism, Chemistry and so on. But when we try to apply this classical view of the scientific method to the various branches of Computer Science and Computer Engineering, among which Software Engineering, we find two kinds of obstacles. First, Computer Science is rooted both in formal sciences such as Mathematics and experimental sciences such as Physics, therefore an excessive emphasis on the experimental side is not appropriate to give a full account of this kind of scientific activity. Second, the production of software systems has to deal not only with the behavior of complex physical systems such as computers, but also with the behavior of complex human systems (developers interacting with stakeholders, for instance, or users interacting with machines) where educational, cultural, sociological and economical factors are essential. Therefore, empirical methods in their narrow sense, even though valuable in some respects, are rather limited to understand a reality that exceeds the mere physical world. Moreover, neither formal nor empirical methods can provide a full account of scientific activity, which relies on something that is beyond any established method. Qualitative (i.e. meta-methodical) reasoning plays the directive role in scientific activity. In this chapter we claim that acknowledging a plurality of research methods in software engineering will benefit the advancement of this branch of science.
CA 125 - ein Tumormarker in der Inneren Medizin?

Bei der retrospektiven Analyse von 1.407 CA 125Bestiinmungen im Serum für die Medizinische Kliniken wiesen 27 % einen erhöhten CA 125-Wert auf. Für die Beurteilung der klinischen Wertigkeit standen die Daten von 200 Patienten mit pathologischen CA 125-Resultateii zur Verfügung. Dieses Patientenkollektiv ließ sich in zwei gleich große Gruppen mit maligner und nicht-maligner Grunderkrankung aufteilen. CA 125-Werte von > 350 U/ml waren nur bei Patienten mit Malignomen und bei Patienten mit Leberzirrhose zu finden. Met äs tarierende Carcinomc wiesen Werte > 1000 U/ml auf. Andere nichtmaligne Erkrankungen waren mit CA-125-Aktivitäten von < 350 U/ml verbunden. Körperhöhlenergüsse (Pleura, Peritoneum, Perikarcl) zeigten sich bei 35% der untersuchten Patienten mit erhöhten CA 125-Werten. Dabei waren 53 % dieser Ergüsse zytopathologisch maligne. Summary
Performance Analysis of a Non-Orthogonal Multiple Access based Cooperative Relaying System over Rician Fading Channels

Non-orthogonal multiple access (NOMA) is the key to the multiple access technique for the fifth generation (5G) wireless communications. In order to improve the performance gains of NOMA systems, a relay assisted cooperative NOMA scheme is investigated in this paper considering the achievable rate of signals as the performance metric. In this technique, by exploiting the concept of NOMA, the second time slot is utilized for the realization of information sent from the transmitter end. In conventional cooperative relaying systems, the receiver is only able to receive a single bit of information, while the receiver can reliably bring in two data symbols in two time slots. In this regard, this scheme is able to acquire higher achievable rate performance than existing cooperative relaying schemes. Furthermore, the requirement of the complex power allocation algorithm is no longer needed, which alleviate the complexity of cooperative NOMA systems. We derive the exact expressions for the average achievable rate for the signals for the two time slots. Additionally, asymptotic results are presented in order to achieve less complex and more accurate results. The results are verified through Monte-Carlo simulations which validate the accuracy and consistency of the derived analytical results. \end{abstract}
Influence of the method of whole wheat inclusion on performance and caecal microbiota profile of broiler chickens

A study was conducted to investigate the effect of method of whole wheat inclusion on performance and caecal microbiota profile of broiler chickens. Fluorescencein situhybridisation analysis was used to characterise the microbiota by using genus-specific probes. Three treatments, namely, ground wheat (GW) or 200 g/kg whole wheat (WW) replacing GW before or after pelleting were evaluated. A total of 144, one-day-old male broilers (Ross 308) were allocated to 18 cages (eight broilers per cage) based on body weight and six cages were randomly assigned to each treatment. The diets were offeredad libitumfrom day 11 to 35 post-hatch. The WW fed birds, regardless of the method of inclusion, resulted in poorer weight gain (P < 0.05) and reduced feed intake (P < 0.001), but a similar feed per gain (P > 0.05) compared to those fed the GW diet. The WW diet, regardless to the method of inclusion, had no effect (P > 0.05) on the populations ofLactobacillusandBacteroides spp.compared with the GW diet. TheBifidobacterium spp.population was higher (P < 0.05) in birds fed the GW diet compared with WW feeding, regardless of the method of inclusion. A reduction (P < 0.05) in the numbers of pathogenicClostridiumandCampylobacter spp.were observed in caecal samples from birds fed WW diets, regardless of method of inclusion, compared with those fed the GW diet, which was attributed to increased gizzard activity. Birds fed WW diets, regardless to the method of inclusion, showed a reduction in gizzard pH (P < 0.05), microbial gas production (P < 0.05), and an increase in gizzard weight (P < 0.05) relative to the GW treatment. The results indicated that the gizzard has an important function as a barrier organ, one that prevents pathogenic bacteria from entering the distal digestive tract.

La politique de mobilite internationale encourage aujourd’hui toutes les formations universitaires du secteur LANSAD a integrer la creation d’un CV dans leur formation en langue.La redaction d’un CV, deja complexe en langue maternelle, reclame pour d’autres langues la maitrise de savoir-faire specifiques a la culture consideree et de contenus linguistiques hautement specialises.L’application web « CV multilingue automatise » decrite dans cet article propose une approche innovante de cette tâche, en fonction des principes cles suivants : l’automatisation de la creation du CV, la specialisation des contenus, l’enrichis-sement de la base de donnees par travail collaboratif, la moderation des contenus par un groupe d’experts et la promotion du plurilinguisme.
Svalbard reindeer (Rangifer tarandus platyrhynchus) antler characteristics reflecting the local environmental conditions

Abstract A new non-invasive method based on picture analysis was used to estimate the conditions in Svalbard reindeer populations. The well-being of an individual subject is often expressed through visual indices. Two distinct reindeer populations were compared based on their antler parameters. Relative antler size and number of tines are variables supposed to reflect correspondingly the environmental conditions of sedentary populations within the growing season. The occurrence areas of two studied populations are distinctly isolated – separated with high mountain ridges, glaciers and fjords. The population in Petuniabukta occupies a sparsely vegetated region with harsh climatic conditions, whereas Skansbukta represents an area with continuous tundra vegetation cover, milder climatic conditions and, consequently, also a longer vegetation season. These environmental factors probably caused significant differences in the relative antler size and number of tines in the studied species. The Skansbukta population exhibited a larger relative antler size and higher number of tines than the population in Petuniabukta (both parameters differed significantly, p < 0.01). This difference reflects concisely the different environmental conditions of both locations. A comparison of Skansbukta population antler characteristics between years 2017 and 2018 did not reveal significant changes, most probably due to very similar atmospheric conditions in these two years (in terms of air temperature).
EFFORT TO GET SAFE RICE FOR CONSUMPTION THROUGH BIOREMEDIATION TECHNOLOGY IN PADDY FIELD CONTAMINATED BY LEAD

Textile industry that has less optimal waste management due to the absence of a wastewater treatment plant (WWTP) tends to dispose the waste directly into the water or river. Most farmers near industrial area use liquid waste for irrigation water. This generates negative impacts of complicated problems in the agricultural sector, especially heavy metals contamination in paddy soils. In such case, bioremediation can be done to handle the contaminated soils by heavy metals to create a healthy farming environment. The purpose of this study was to determine the effectiveness of the chelating agents ( Agrobacterium sp. I 37 or compost) to the characteristic of soil and the level of Pb in rice plant. This study was conducted between June - September 2017 in Tasikmadu, Karanganyar, Indonesia. The experimental design was factorial using randomized completely block design (RCBD) as the based design. There are two factors in this research: a) inorganic fertilizer (P): without inorganic fertilizer (P0) with inorganic fertilizer (P1); b) chelator (B): without chelator (B0), with chelator Agrobacterium sp I 37 (B1), with chelator compost (B2). There were six treatment combinations then replicated 3 times for each treatment, so there were 18 unit treatments. The results showed that Agrobacterium sp. I 37 or compost can decrease soil Pb. The best treatment in decreasing soil Pb was treatment using Agrobacterium sp. I 37 , which soil Pb decreased of 42.91% from 8.04 mg/kgto 4.59 mg/kg; could enhance accumulation of Pb in the roots of 69, 63% and decrease Pb levels in rice grains around 55.67% higher than control treatment.
Simulation-Based Prototyping of Stability Control Concepts For High-Speed Teleoperation of Heavy Vehicles

Teleoperated ground vehicles are an integral part of the U.S. Army and Marine Corps long range vision and a key transition technology for fully autonomous vehicles. However, the combination of marginally-stable vehicle dynamics and limited perception are a key challenge facing teleoperation of such platforms at higher speeds. New technologies for enhancing operator perception and automatically detecting and mitigating rollover risk are needed to realize sufficient safety and performance in these applications. This paper presents three rollover mitigation concepts for high speed teleoperation of heavy tactical vehicles, including model-predictive warning, negative obstacle avoidance, and reactive brake controls. A modeling and simulation approach was used to evaluate these concepts within the Autonomous Navigation Virtual Environment Laboratory (ANVEL). Vehicle models for both the M1078 cargo truck and RG-31 MRAP were used throughout concept evaluation over terrain ranging from urban highway to off-road conditions with more complex topography.
On Using the t-Ratio as a Diagnostic

The t-ratio has not one but two uses in econometrics, which should be carefully distinguished. It is used as a test and also as a diagnostic. I emphasize that the commonly-used estimators are in fact pretest estimators, and argue in favor of an improved (continuous) version of pretesting, called model averaging.
Dynamique spatialement et temporellement hétérogène dans la relaxation lente de la matière molle vitreuse

Ce travail est consacre a l'etude des heterogeneites dynamiques dans la relaxation lente de la matiere molle vitreuse par des techniques originales de diffusion de la lumiere multispeckle, developpees au cours de cette these. La premiere technique, appelee « Correlation Resolue dans le Temps » (TRC), permet de caracteriser les heterogeneites temporelles de la dynamique. Elle a ete optimisee en considerant un systeme modele, les mousses. Nous avons propose diverses methodes pour supprimer la contribution du bruit de la mesure, due au nombre limite de pixels de la camera CCD, dans des objets statistiques caracterisant les fluctuations de la dynamique (variance, fonction densite de probabilite et autocorrelation). La deuxieme technique, appelee « Correlation Resolue dans le Temps et dans l'Espace » (STRC), permet de caracteriser les heterogeneites spatiales de la dynamique. Grâce a la STRC, nous avons montre que la dynamique d'un gel concentre de vesicules lamellaires et celle d'un gel colloidal fortement attractif sont, de facon surprenante, correlees sur des distances tres longues. Des mesures complementaires sur le gel colloidal, effectuees a plusieurs vecteurs de diffusion, ont mis en evidence la dependance de la dynamique moyenne et de ses fluctuations temporelles avec la longueur sondee. Nous avons etabli un modele simple, base sur une serie de rearrangements correles spatialement et aleatoires dans le temps, qui est en accord avec les resultats experimentaux.
Termination of pre-mRNA splicing requires that the ATPase and RNA unwindase Prp43p acts on the catalytic snRNA U6

The termination of pre-mRNA splicing functions to discard suboptimal substrates, thereby enhancing fidelity, and to release excised introns in a manner coupled to spliceosome disassembly, thereby allowing recycling. The mechanism of termination, including the RNA target of the DEAH-box ATPase Prp43, remains ambiguous. We discovered a critical role for nucleotides at the 3’-end of the catalytic U6 small nuclear RNA in splicing termination. Though conserved sequence at the 3’-end is not required, 2’ hydroxyls are, paralleling requirements for Prp43 biochemical activities. While the 3’-end of U6 is not required for recruiting Prp43 to the spliceosome, the 3’ end crosslinks directly to Prp43 in an RNA-dependent manner. Our data indicate a mechanism of splicing termination in which Prp43 translocates along U6 from the 3’ end to disassemble the spliceosome and thereby release suboptimal substrates or excised introns. This mechanism reveals that the spliceosome becomes primed for termination at the same stage it becomes activated for catalysis, implying a requirement for stringent control of spliceosome activity within the cell.
Life Café. A Co-Designed Method of Engagement

The last decade has witnessed a demographic change on unprecedented scale - people are living longer and with more complex, long term conditions. This paper presents a programme which seeks to rethink how palliative and end of life care can be provided equitably, efficiently and sustainably for future generations. It explores the methodological approach undertaken by university researchers, to engage communities in conversations around a topic often seen as taboo. The community engagement focuses on understanding what is important to individuals in life, care, and end of life. A methodology, named the Life Cafe, has been developed to gather research in an informal manner within community groups and familiar environments. The Life Cafe comprises critical artefacts, activities and resources, co-developed with community members developed to answer the research questions. The Life Cafe has become a product that can be used across different services to establish what matters to individuals and enable difficult conversations.
Local and global Hopf bifurcation in a neutral population model with age structure

In this paper, an age‐structured population model with the form of neutral functional differential equation is studied. We discuss the stability of the positive equilibrium by analyzing the characteristic equation. Local Hopf bifurcation results are also obtained by choosing the mature delay as bifurcation parameter. On the center manifold, the normal form of the Hopf bifurcation is derived, and explicit formulae for determining the criticality of bifurcation are theoretically given. Moreover, the global continuation of Hopf bifurcating periodic solutions is investigated by using the global Hopf bifurcation theory of neutral equations. Finally, some numerical examples are carried out to support the main results.
Application of Extension Neural Network with Discrete Wavelet Transform and Parseval’s Theorem for Power Quality Analysis

The development of renewable energy and the increase of intermittent fluctuating loads have affected the power quality of power systems, and in the long run, damage the power equipment. In order to effectively analyze the quality of power signals, this paper proposes a method of signal feature capture and fault identification, as based on the extension neural network (ENN) algorithm combined with discrete wavelet transform (DWT) and Parseval’s theorem. First, the original power quality disturbance (PQD) transient signal was subjected to DWT, and its spectrum energy was calculated for each order of wavelet coefficients through Parseval’s theorem, in order to effectively intercept the eigenvalues of the original signal. Based on the features, the extension neural algorithm was used to establish a matter-element model of power quality disturbance identification. In addition, the correlation degree between the identification data and disturbance types was calculated to accurately identify the types of power failure. To verify the accuracy of the proposed method, five common power quality disturbances were analyzed, including voltage sag, voltage swell, power interruption, voltage flicker, and power harmonics. The results were then compared with those obtained from the back-propagation network (BPN), probabilistic neural network (PNN), extension method and a learning vector quantization network (LVQ). The results showed that the proposed method has shorter computation time (0.06 s), as well as higher identification accuracy at 99.62%, which is higher than the accuracy rates of the other four types.

Change in physiological parameters of calves of various breeds under the transport and pre-slaughter stress

Levakhin VI, Gorlov IF, Azhmuldinov EA, Levakhin YI, Duskaev GK, Zlobina EY, Karpenko EV. 2017. Change in physiological parameters of calves of various breeds under the transport and pre-slaughter stress. Nusantara Bioscience 9: 1-5. The purpose of the research was to study the effect of the animal breed on the stress resistance of young cattle during the motor transportation. Six groups of animals were chosen for the experiment. The first group consisted of calves crossbred from dairy Black and White cows with Hereford bulls, the second â€“ of calves crossbred from dairy cows of Bestuscheff breed with Hereford bulls, the third â€“ of calves purebred of Simmental, the fourth â€“ of calves purebred of Hereford, the fifth â€“ of calves purebred of Aberdeen-Angus, and the sixth â€“ of calves purebred of Limousine breed. The total length of transport was 180 km of highways and local roads. The route consisted of a 5-hour trip without a rest period. The greatest loss in the body weight was determined in the Limousine calves. The calves purebred of Hereford and Simmental breeds are more stress-resistant during the transporting and the pre-slaughter treatment.
Improvement of the Time Resolution of Radiation Detectors Based on Gd3Al2Ga3O12 Scintillators With SiPM Readout

Coincidence time resolution (CTR) of scintillation detectors based on Ce- and Mg-codoped Gd3Al2Ga3O12 (GAGG) scintillation crystals and high-density silicon photomultipliers (SiPMs) is shown to be 165 ps (full width at half maximum) for 511-keV $\gamma $ -quanta, approaching that achieved by using LSO scintillators. To study the prospective for further improvement of the time resolution, the population of the emitting Ce centers was investigated by optical pump and probe technique using selective photoexcitation and probing by a white light continuum with subpicosecond time resolution. The importance of free electron trapping for excitation transfer to emitting Ce ions was revealed. The influence of transfer delay on the scintillation response time is described, and the dynamics of electron relaxation to the lowest excited level of Ce ion is studied experimentally and analyzed by taking into account intracenter relaxation and relaxation via conduction band. The influence of electron diffusivity on the rise time of the population of the emitting level is described. It is shown that codoping of GAGG:Ce by magnesium even at the level as low as 10 ppm efficiently decreases the scintillator response time by enhancing the electron diffusivity.
