description: One major objective of software testing is to reveal software failures such that program bugs can be removed. Random testing is a basic and simple software testing technique, but its failure-detection effectiveness is often controversial. Based on the common observation that program inputs causing software failures tend to cluster into contiguous regions, some researchers have proposed that an even spread of test cases should enhance the failure-detection effectiveness of random testing. Adaptive random testing refers to a family of algorithms to evenly spread random test cases based on various notions. Restricted random testing, an algorithm to implement adaptive random testing by the notion of exclusion, defines an exclusion region around each previously executed test case, and selects test cases only from outside all exclusion regions. Although having a high failure-detection effectiveness, restricted random testing has a very high computation overhead, and it rigidly discards all test cases inside any exclusion region, some of which may reveal software failures. In this paper, we propose a new method to implement adaptive random testing by exclusion, where test cases are simply selected based on a welldesigned test profile. The new method has a low computation overhead and it does not omit any possible program inputs that can detect failures. Our experimental results show that the new method not only spreads test cases more evenly but also brings a higher failure-detection effectiveness than random testing.

description: The non-catalytic high-temperature oxidation of hexafluoropropene (HFP) by gaseous oxygen was carried out isothermally in a long tubular reactor (length 114.3 m, 1/8 inch nominal diameter). The process was investigated at a total pressure of 450 kPa and over the temperature range of 453 to 503 K. Feed mixtures comprising 20 to 67% HFP in oxygen were used at total flowrates between 150 and 550 cm3 · min−1, resulting in space times from 80 to 160 s. 2,2,3-Trifluoro-3-(trifluoromethyl)-oxirane (hexafluoropropene oxide, HFPO), trifluoroacetyl fluoride and carbonyl fluoride were identified as major oxidation products. In addition, tetrafluoroethene and hexafluorocyclopropane were found in the exit gas as well. The reactor operating conditions were optimized independently for HFPO selectivity and yield using a quadratic response surface technique. A maximum HFPO selectivity of 55.81% was found at conditions of 478.2 K, a HFP/O2 molar feed ratio of 1.34 mol · mol−1 and a space time of 113 s. An optimum HFPO yield of 40.1% was identified at conditions of 483.2 K, a HFP/O2 molar feed ratio of 1.16 mol · mol−1 and a space time of 121 s. Using a multi-response optimization technique, a combined optimum HFPO selectivity and yield of 56% and 40%, respectively, was obtained at conditions of 480 K, a HFP/O2 molar feed ratio of 1.21 mol · mol−1 and a space time of 118 s. This represented the best trade-off between these two performance criteria. A parallel scale-up strategy was suggested for increasing throughput for industrial application.

Isolating Suspiciousness from Spectrum-Based Fault Localization Techniques

description: Spectrum-based fault localization (SBFL) is one of the most promising fault localization approaches, which normally uses the failed and passed program spectrum to evaluate the risks for all program entities. However, it does not explicitly distinguish the different degree in definiteness between the information associated with the failed spectrum and the passed spectrum, which may result in an unreliable location of faults. Thus in this paper, we propose a refinement method to improve the accuracy of the predication by SBFL, through eliminating the indefinite information. Our method categorizes all statements into two groups according to their different suspiciousness, and then uses different evaluation schemes for these two groups. In this way, we can reduce the use of the unreliable information in the ranking list, and finally provide a more precise result. Experimental study shows that for some SBFL techniques, our method can significantly improve their performance in some situations, and in other cases, it can still remain the techniques' original performance.

description: Terrain rendering is a crucial part of many real-time applications. The easiest way to process and visualize terrain data in real time is to constrain the terrain model in several ways. This decreases the amount of data to be processed and the amount of processing power needed, but at the cost of expressivity and the ability to create complex terrains. The most popular terrain representation is a regular 2D grid, where the vertices are displaced in a third dimension by a displacement map, called a heightmap. This is the simplest way to represent terrain, and although it allows fast processing, it cannot model terrains with volumetric features. Volumetric approaches sample the 3D space by subdividing it into a 3D grid and represent the terrain as occupied voxels. They can represent volumetric features but they require computationally intensive algorithms for rendering, and their memory requirements are high. We propose a novel representation that combines the voxel and heightmap approaches, and is expressive enough to allow creating terrains with caves, overhangs, cliffs, and arches, and efficient enough to allow terrain editing, deformations, and rendering in real time.
Trade liberalization and poverty reduction in the WAEMU area

description: The objective of this paper is to examine the impact of trade openness on poverty based on data from a panel of eight countries of the West African Economic and Monetary Union between 1993 and 2021. The adopted methodological approachis mainly based on the analysis of panel data. Our results indicate that trade openness contributes significantly to poverty reduction. However, it is important to note that the growth channel, often discussed in the theoretical literature, remains insignificant in the relationship between trade openness and poverty. This finding is partly explained by the fact that the benefits of openness are spread across the economy and cannot be attributed simply to improvements in growth.

description: Background: Subacute sclerosing panencephalitis (SSPE) is a disease of childhood and adolescence, but can affect adults. Rapidly progressive cognitive decline, seizures including myoclonic jerks, spasticity, ataxia, visual disturbances, and incontinence are typical manifestations. Case report: A 62-year-old woman who presented with rapidly progressive dementia and myoclonus was diagnosed with SSPE. There was resolution of the movement disorder with clonazepam and valproic acid treatment and some amelioration of cognitive decline after 3 months of therapy with interferon alfa and isoprinosine. Discussion: With the recent rise in measles cases worldwide, any increased incidence of SSPE would require vigilance for early interventions.

description: The cholesteryl ester transfer protein (CETP), inhibition of which assists in maintaining a high level of high-density lipoprotein cholesterol in the blood, is a target for anti-atherosclerosis treatments. Orange monascus pigment was produced by a Monascus species in a 5 L jar fermenter and various derivative compounds were synthesised by incorporating 19 different l-amino acids into the orange pigment. Among them, the l-Thr and l-Tyr derivatives exhibited high inhibitory activities against the CETP reaction. The inhibitory activities of the l-Thr and l-Tyr derivatives increased in a dose-dependent manner, resulting in IC50 values of 1.0 and 2.3 μM, respectively. When CETP reactions in the presence of the derivatives were performed, the inhibition modes of the l-Thr and l-Tyr derivatives were non-competitive with inhibition constant (Ki) values of 2.7 and 4.3 μM, respectively.

description: Simplified molecular input line entry system (SMILES) notations of 116 π-conjugated organic compounds have been used in three random splits to develop single optimal descriptor based quantitative structure–property relationships (QSPR) models for the prediction of dielectric constants by CORAL (CORrelation And Logic). Four kinds of optimal descriptors were obtained based on SMILES, hydrogen suppressed graph (HSG), graph of atomic orbitals (GAO) and hybrid descriptors. The Monte Carlo optimization was carried out for each random split by three different methods: (i) classic scheme; (ii) balance of correlations; and (iii) balance of correlations with ideal slopes. The QSPR models gave reliable and accurate values of dielectric constant for all the π-conjugated organic compounds. SMILES and the hybrid-based QSPR model provided the best accuracy for the prediction of dielectric constants. Statistical characteristics of the QSPR model-1 based on classic scheme method are n = 110, r2 = 0.860, Q2 = 0.860, s = 1.84, MAE = 1.30 and F = 696 (training set), n = 6, r2 = 0.947, Q2 = 0.876, s = 0.955, MAE = 0.647 and F = 71 (test set). These QSPR models are further validated by an external validation set of 25 molecules and the robustness is checked by parameters like k, kk, rm2, r*m2, average rm2, ∆rm2and randomization technique ().

description: A recent study has classified faults in Boolean expressions into ten classes and has proved that there are five key fault classes, namely CCF, CDF, ORF, ENF and ASF, such that if a test suite can kill all faulty versions of these five core fault classes, if can kill all faulty versions of all fault classes. In order to generate more effective test suites, we should prioritize these five fault classes further, such that test cases with stronger fault detection capability could be generated as early as possible. Such a process is referred to as the fault class prioritization. Based on the observation in the fault class hierarchy, we divide the five fault classes into two groups {CCF, CDF} and {ORF, ENF, ASF}. Two strategies of fault class prioritization are proposed to generate test cases efficiently. We design experiments using TCAS Boolean expressions and some randomly generated Boolean expressions. The experimental results suggest that if we generate test cases for CCF and CDF firstly, the final test suite always have a higher efficiency of killing faults.

Year: 2022

description: Background: CYP4V2 polymorphisms were related to with venous thromboembolism. However, it is unclear on the influence of CYP4V2 polymorphisms on the susceptibility of ischemic stroke (IS). Methods: We selected and genotyped five polymorphisms in CYP4V2 to test whether CYP4V2 variants confer to the risk for IS in a Chinese Han population with 575 cases and 575 controls. Genotyping of CYP4V2 polymorphisms was performed using the Agena MassARRAY platform. Logistic regression analysis was used for the association by calculating odds ratios (ORs) and 95% confidence interval (CI). False-positive report probability (FPRP) analysis was applied to assess the noteworthy relationship of the significant findings. Results: Rs1398007 might be a risk factor for IS occurrence (OR = 1.34, 95% CI: 1.05–1.71, p = 0.009). Specially, confounding factors (age, gender, smoking and drinking status) might contribute to the relationship of rs1398007 with IS susceptibility. Moreover, rs1053094 and rs56413992 were associated with IS risk in the male population. Multifactor dimension reduction (MDR) analysis showed a combination of rs13146272 and rs3736455 with the strongest interaction effect (information gain values of 0.40%). Furthermore, the genotypes of rs1398007 (p = 0.006) and rs1053094 (p = 0.044) were associated with the levels of HDL-C among healthy controls. Conclusions: Our results firstly provided evidence that CYP4V2 rs1398007 might be a risk factor for IS occurrence, which might provide instructive clues for CYP4V2 to the pathogenesis of IS.

description: We extend the subtractive imaging method to label-free second harmonic generation (SHG) microscopy to enhance the spatial resolution and contrast. This method is based on the intensity difference between two images obtained with circularly polarized Gaussian and doughnut-shaped beams, respectively. By characterizing the intensity and polarization distributions of the two focused beams, we verify the feasibility of the subtractive imaging method in polarization dependent SHG microscopy. The resolution and contrast enhancement in different biological samples is demonstrated. This work will open a new avenue for the applications of SHG microscopy in biomedical research.

description: This study reports the production and biochemical characterisation of a thermostable alkaline halophilic protease from Natronolimnobius innermongolicus WN18 (HQ658997), isolated from soda Lake of Wadi An-Natrun, Egypt. The enzyme was concentrated by spinning through a centriplus, centrifugal ultrafiltration Millipore membrane with a total yield of 25%. The relative molecular mass of this protease determined by sodium dodecyl sulfate–polyacrylamide gel electrophoresis ranged from 67 to 43 kDa. The extracellular protease of N. innermongolicus WN18 was dependent on high salt concentrations for activity and stability, and it had an optimum temperature of 60°C in the presence of 2.5 M NaCl. This enzyme was stable in a broad pH range (6–12) with an optimum pH of 9–10 for azocasein hydrolysis. This extracellular protease, therefore, could be defined as thermostable and haloalkaliphilic with distinct properties that make the enzyme applicable for different industrial purposes.

description: Lehrer*innen und Schulleitungen sehen sich in der Organisation Schule vielfältigen Herausforderungen gegenübergestellt. Dazu zählen u.a. der gesellschaftliche Wandel, der Umgang mit Heterogenität, die fortschreitende Digitalisierung oder die COVID-19-Pandemie. Das Fundament für einen situationsadäquaten Umgang mit derartigen Herausforderungen im Lehrberuf legt dabei die Lehrer*innenbildung. Sie ist gefordert, bei Studierenden ein professions- und schulbezogenes Entwicklungswissen grundzulegen. Dieser Beitrag geht deshalb der Frage nach, wie ein professionstheoretisches Wissensmodell aussehen könnte, in dem Wissensfacetten für den Bereich Schulentwicklung berücksichtigt werden. Empirisch gründet dieses Modell auf einer qualitativen Untersuchung, die sich der Fragestellung methodisch mittels Curriculumsanalysen und Expert*innen-Interviews annähert. Das Modell hält zentrale Facetten eines Schulentwicklungswissens – als Teil des (allgemein-)pädagogischen Wissens von Lehrer*innen – fest und zeigt im Ergebnis, dass sich Grundlagenwissen für den Bereich Schulentwicklung aus Wissen über die Lehrer*innen-Profession (Professionsverständnis), das Schulsystem und die Schule als Arbeitsplatz sowie Schulentwicklungsinstrumente zusammensetzt und dass für den Erwerb von Schulentwicklungswissen auch in Praktika und der Berufseingangsphase Möglichkeiten bereitgestellt werden sollten.

description: Accurately tuning the macroscopic properties of biopolymer‐based hydrogels remains challenging due to the ill‐defined molecular architecture of the natural building blocks. Here, we report a biohybrid coacervate hydrogel, combining the biocompatibility and biodegradability of naturally occurring hyaluronic acid (HA) with the tunability of a synthetic polyethylene oxide (PEO) ‐based ABA‐triblock copolymer. Coacervation of the cationic ammonium or guanidinium‐functionalized copolymer A‐blocks with the anionic HA leads to hydrogel formation. Both mechanical properties and water content of the self‐healing hydrogels can be controlled independently by altering the copolymer structure. By controlling the strength of the interaction between the polymer network and small‐molecule cargo, both release rate and maximum release are controlled. Finally, we show that coacervation of HA and the triblock copolymer leads to increased biostability upon exposure to hyaluronidase. We envision that noncovalent crosslinking of HA hydrogels through coacervation is an attractive strategy for the facile synthesis of tunable hydrogels for biomedical applications.

Konkobo et Issaka Sawadogo Le Burkina Faso des années 2000 a connu un véritable boom du secteur minier, aussi bien dans l’exploitation industrielle que celle artisanale. L’orpaillage traditionnelle présente une caractéristique clé de l’exploitation de l’or au Burkina Faso. Malgré ses effets environnementaux et sociaux indésirables, l’orpaillage constitue une source de revenue et de développement importante en milieu rural. En 2017, l’Agence Nationale d’Encadrement de l’Exploitation Minière Artisanale et Semi-mécanisée (ANEEMAS) a été suscitée comme nouvelle structure par l’Etat du Burkina Faso et ses partenaires pour promouvoir la formalisation de l’exploitation artisanale. Cependant, elle rencontre aussi des réactions et sentiments ambivalents du côté des acteurs de l’exploitation minière artisanale. C’est dans ce contexte qu’intervient la présente étude par la description du secteur, des acteurs de la chaîne opératoire de l’exploitation artisanale et leur vécu quotidien. Elle présente, en outre, une analyse de la politique d’encadrement de l’exploitation minière artisanale à travers l’ANEEMAS, la perception des acteurs impliqués dans la chaîne opératoire sur le terrain et propose des amélioraitions d'accompagnement des mineur.euse.s.

description: Finding new ways to control and slow down the group velocity of light in media remains a major challenge in the field of optics. For the design of plasmonic slow light structures, graphene represents an attractive alternative to metals due to its strong field confinement, comparably low ohmic loss and versatile tunability. Here we propose a novel nanostructure consisting of a monolayer graphene on a silicon based graded grating structure. An external gate voltage is applied to graphene and silicon, which are separated by a spacer layer of silica. Theoretical and numerical results demonstrate that the structure exhibits an ultra-high slowdown factor above 450 for the propagation of surface plasmon polaritons (SPPs) excited in graphene, which also enables the spatially resolved trapping of light. Slowdown and trapping occur in the mid-infrared wavelength region within a bandwidth of ~2.1 μm and on a length scale less than 1/6 of the operating wavelength. The slowdown factor can be precisely tuned simply by adjusting the external gate voltage, offering a dynamic pathway for the release of trapped SPPs at room temperature. The presented results will enable the development of highly tunable optoelectronic devices such as plasmonic switches and buffers.

description: While some pronouncements of expert treaty bodies have been considered ‘key catalysts’ for the development of international human rights law, others are only selectively referred to in legal practice. This article argues that the varying normative impact is due to the informal character of pronouncements. In the absence of treaty provisions specifying their legal effect, practitioners tend to rely on different factors and arguments when either drawing on or rejecting certain pronouncements. Scholars in turn face difficulties when trying to identify explanatory patterns within this diverging practice as the informal character confronts both international lawyers and international relations scholars with their respective methodological ‘blind spots’. In light of these intradisciplinary challenges, this article explores the extent as to which an interdisciplinary approach helps to assess the reasons for the varying impact of pronouncements. After analysing the factors determining their legal significance on the basis of State practice and the academic debate, this article identifies the drafting process as a factor which promises to be particularly insightful when explored from an interdisciplinary perspective and sketches out a framework for future research.

description: The guarantee of judicial independence is undoubtedly one of the most important institutional design features of international courts and tribunals. An independence deficit can adversely impact a court’s authority, create a crisis of legitimacy, and undermine the very effectiveness of an international court or tribunal. It can hardly be denied that for an international court to be considered legitimate, a basic degree of independence is a must. An independent judiciary is a precondition to the fair and just resolution of legal disputes. In the context of interstate dispute settlement where the jurisdiction of courts is based on the principle of consent, in the absence of a basic degree of judicial independence, states may not be willing to submit to the jurisdiction of international courts. Comparing and contrasting the International Court of Justice and the Appellate Body of the World Trade Organisation, I assess whether those international judicial mechanisms possess the basic degree of independence required for a court to be able to maintain its credibility so that it can continue to perform its core function of adjudicating interstate disputes. With both those interstate adjudicative bodies constituting the two leading international courts in terms of participation and the sheer number of cases decided, much may be learned from comparing them. I argue there is a case for bolstering the independence of the ICJ; and without immediate reforms to the Appellate Body’s institutional design, its recent demise may become permanent. I conclude that if a basic degree of judicial independence cannot be guaranteed, it is preferable to let a court vanish for a while than to maintain a significantly deficient one.

description: Two volatile samples of the bryozoan Hyalinella punctata (seasonally collected from the same locality) were isolated (hydrodistillation, Clevenger apparatus), identified (GC and GC–MS) and screened in vitro (EPR) for anti-hydroxyl radical activity. The main components of sample 1 (2-ethyl-1-hexanol 37.00%, dodecanol 21.40% and hexanal 8.40%) and sample 2 (2-ethyl-1-hexanol 30.50%, 7-tridecanol 24.60% and 1-hexadecanol 11.80%) were relatively similar. However, more components were present in the sample 2 (17 and 25, respectively). EPR measurements indicated significant anti-hydroxyl radical activity of the both samples (75.00 ± 6.00% and 87.00 ± 8.00%, respectively) whereas the generation of other types of free radicals in reaction with hydroxyl radicals was not observed. According to the best of our knowledge, this is the first report of 31 organic compounds from the phylum Bryozoa. Alcohols, aldehydes, ketones, esters and ethers of lower molecular mass appear to be characteristic for the volatiles of these organisms commonly known as moss animals.

description: For the United States the ‘international law of global security’ is, in a unique sense, synonymous with the entire project of constructing global legal order. Uniquely preponderant power enjoyed since the end of the Second World War has allowed US preferences to manifest not merely in specific rules and regimes, but in purposive development of the entire structure of global legal order to favour American security interests. Perceptions of a recent decline in this order now find expression in advocacy for a ‘liberal’ or ‘rules-based’ international order, as the claimed foundation for global prosperity and security. This working paper seeks to map out the parameters of US contributions to the global security order by uncovering the strategic and political foundations of its engagement with the international law of global security. The paper begins by reflecting on competing US conceptions of the relationship between national security and global order as they evolved across the twentieth century. The focus then turns to three significant trends defining the contemporary field. First are US attitudes toward multilateral institutions and global security, and the ongoing contest between beliefs that they are mutually reinforcing versus beliefs that US security and global institutions sit in zero-sum opposition. Second is the impact of the generational ‘War on Terror’, which has yielded more permissive interpretation and development of laws governing the global use of violence. The final trend is that towards competitive geopolitical interests restructuring international law, which are evident across diverse areas ranging from global economics, to cybersecurity, to the fragmentation of global order into spheres of influence. Looking ahead, a confluence of rising geopolitical competitors with divergent legal conceptions, and conflicted domestic support for the legitimacy and desirability of US global leadership, emerge as leading forces already reshaping the global security order.
Towards genre classification in anglophone West Africa video films: the case of Scorned as a woman’s film

description: This paper explores the woman’s film within the context of Africa and African cinematography by examining the Ghanaian video film Scorned (2008), written and directed by Shirley Frimpong-Manso. It examines the themes, narrative structure, and cinematic style employed in the Ghanaian video film Scorned (2008), comparing it to the key elements of the 1930s – 1950s woman’s film genre of Hollywood. We argue that Scorned follows the traditional genre of the woman’s Hollywood movie while simultaneously subverting some of the ingrained conventions and expectations of that genre. The film merges and renegotiates the generic elements of the woman’s film as represented in the Hollywood woman’s film genre and melodrama by focusing on the underpinning ideologies, plot, and aesthetics in making visible the Ghanaian woman’s experience and constructing a female consciousness. Such engagements can contribute to teasing out some of the generic elements, which could constitute the African woman’s film.

description: Saccadic suppression - the reduction of visual sensitivity during rapid eye movements - has previously been proposed to reflect a specific suppression of the magnocellular visual system, with the initial neural site of that suppression at or prior to afferent visual information reaching striate cortex. Dysfunction in the magnocellular visual pathway has also been associated with perceptual and physiological anomalies in individuals with autism spectrum disorder or high autistic tendency, leading us to question whether saccadic suppression is altered in the broader autism phenotype. Here we show that individuals with high autistic tendency show greater saccadic suppression of low versus high spatial frequency gratings while those with low autistic tendency do not. In addition, those with high but not low autism spectrum quotient (AQ) demonstrated pre-cortical (35-45 ms) evoked potential differences (saccade versus fixation) to a large, low contrast, pseudo-randomly flashing bar. Both AQ groups showed similar differential visual evoked potential effects in later epochs (80–160 ms) at high contrast. Thus, the magnocellular theory of saccadic suppression appears untenable as a general description for the typically developing population. Our results also suggest that the bias towards local perceptual style reported in autism may be due to selective suppression of low spatial frequency information accompanying every saccadic eye movement.

description: We outline an approach for eliciting, understanding, and representing the cultural aspects of the domestic environment for the purpose of system design. We use agent models as shared artefacts to represent the everyday cultural life of the home. These representations build an understanding between the people that own this culture and the people responsible for technology development. We argue the necessity of knowing about a formal representation of these cultural aspects to inform design decisions and develop technologies that truly satisfy and support the everyday life of families. Our aim is to express socially-oriented requirements for technology. We show the usefulness of this approach on a case study that investigates interactions between grandparents and grandchildren who are geographically separated.
Breaking the diffraction-limited resolution barrier in fiber-optical two-photon fluorescence endoscopy by an azimuthally-polarized beam

description: Although fiber-optical two-photon endoscopy has been recognized as a potential high-resolution diagnostic and therapeutic procedure in vivo, its resolution is limited by the optical diffraction nature to a few micrometers due to the low numerical aperture of an endoscopic objective. On the other hand, stimulated emission depletion (STED) achieved by a circularly-polarized vortex beam has been used to break the diffraction-limited resolution barrier in a bulky microscope. It has been a challenge to apply the STED principle to a fiber-optical two-photon endoscope as a circular polarization state cannot be maintained due to the birefringence of a fiber. Here, we demonstrate the first fiber-optical STED two-photon endoscope using an azimuthally-polarized beam directly generated from a double-clad fiber. As such, the diffraction-limited resolution barrier of fiber-optical two-photon endoscopy can be broken by a factor of three. Our new accomplishment has paved a robust way for high-resolution in vivo biomedical studies.

description: This study reports the production and biochemical characterisation of a thermostable alkaline halophilic protease from Natronolimnobius innermongolicus WN18 (HQ658997), isolated from soda Lake of Wadi An-Natrun, Egypt. The enzyme was concentrated by spinning through a centriplus, centrifugal ultrafiltration Millipore membrane with a total yield of 25%. The relative molecular mass of this protease determined by sodium dodecyl sulfate–polyacrylamide gel electrophoresis ranged from 67 to 43 kDa. The extracellular protease of N. innermongolicus WN18 was dependent on high salt concentrations for activity and stability, and it had an optimum temperature of 60°C in the presence of 2.5 M NaCl. This enzyme was stable in a broad pH range (6–12) with an optimum pH of 9–10 for azocasein hydrolysis. This extracellular protease, therefore, could be defined as thermostable and haloalkaliphilic with distinct properties that make the enzyme applicable for different industrial purposes.
