The impact of organizational support on work spirituality, organizational citizenship behaviour and job performance: The case of Zimbabwe’s small and medium enterprises (SME) sector

Notwithstanding the increasing alertness of the importance of organizational support on employees’ job performance in large firms, research efforts on the same and the mediating influence of workplace spirituality and organizational citizenship behaviour focused on the SMEs sector context have largely been scarce particularly in developing countries of Southern Africa. Therefore, the principal objective of this study is to fill this void. Five research hypotheses are posited and a sample data of 320 collected from the SME employees in Zimbabwe is used to empirically test the hypotheses. The results of this study show that, organizational support positively influences SME employees’ workplace spirituality, citizenship behaviour and consequently their job performance in a significant way. Managerial implications of the findings are discussed and limitations and future research directions are indicated.

Important research progress in clinical practice for advanced breast cancer in 2023

The comprehensive diagnosis and treatment of advanced breast cancer has entered the era of "accurate classification and precise stratification", and is moving towards the road of personalized precision medicine. In 2023, significant breakthroughs have been achieved in the research on different molecular classifications of advanced breast cancer, influencing clinical guidelines and transforming clinical practice. The primary focus of research for hormone receptor positive advanced breast cancer lies in selecting appropriate treatments for patients who have failed cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors. Advanced breast cancer with low human epidermal growth factor receptor 2 (HER2) expression has emerged as a promising treatment direction, with T-DXd being an important therapeutic option. With the release of results from the PHILA study, a new era has begun for first-line treatment of HER2-positive advanced breast cancer. Simultaneously, T-DXd has become the preferred choice in clinical practice following tyrosine kinase inhibitor failure. Research related to immune and targeted therapy for advanced triple-negative breast cancer (TNBC) is also progressing rapidly, yielding positive outcomes in studies such as TORCHILIGHT and BEGONIA. Additionally, ongoing clinical studies on precision treatment based on the "Fudan classification" for TNBC are expected to revolutionize current treatment approaches. This paper summarized major advancements in clinical research on advanced breast cancer in 2023 according to various molecular classifications, aiming to provide improved reference and guidance for clinical management.

Pilot allocation in downlink for cell-free communication systems

In Cell-Free massive Multiple-Input-Multiple-Output (Cell-Free massive MIMO) systems, we distribute in a coverage area a massive number of access points, mastered by central processing units (CPUs), to simultaneously serve much smaller number of user equipments (UEs) over the same time/frequency resources. In contrast to the centralized massive MIMO, cell-free massive MIMO is characterized by a channel hardening not sufficiently accentuated, thus, it will be appropriate to include downlink (DL) pilots to estimate the DL channel. This thesis considers a DL pilot assignment for the cell-free massive MIMO systems by defining a metric, involving the inter-user interference (IUI). This metric gives insights about DL pilot contamination. A threshold is then defined to optimize the number of DL pilots, which maximizes the minimum per-user DL throughput. This approach gives a conflict graph, where each UE is regarded as a vertex of the graph. It consists in a combinatorial optimization problem that can be approximated using a graph coloring algorithm. It is a greedy algorithm whose steps are described as follows. By fixing the adequate threshold, maximizing the minimum per-user DL throughput, a conflict or interference graph is constructed. It models the potential interference among interfering UEs, the UEs between which there is an edge are in conflict, i.e., present a high IUI. Then, the proposed scheme mitigates the potential IUI by appointing different DL pilots to connected UEs with high IUI and same DL pilots to UEs with low IUI in the conflict graph in accordance with some coloring rules. The simulation results validate that the minimum per-user DL throughput based on the proposed approach outperforms the conventional methods, i.e., statistical channel state information, the orthogonal and the random pilot assignment in the DL training. Our analysis underlines also the reduction of the DL pilot overhead ratio using the DL pilot assignment based on our proposed scheme, compared to the conventional methods aforementioned.

Gridsat: a distributed large scale satisfiability solver for the computational grid

Grid Computing is an emerging field in computer science. Research in this area aims at aggregating distributed, heterogenous and federated resources and make it available to Grid applications. In the past two types of applications have been deployed with varying degrees of success. The first type of applications is embarrassingly parallel (a bag of independent tasks). This category adapts well to a computational grid environment. The second category of applications includes mainly scientific code which is tightly coupled in nature. This type of applications is very hard to deploy in a grid environment. 
In this thesis we present GridSAT, a new grid application. GridSAT is a distributed complete Boolean satisfiability sower based on the sequential solver Chaff [70]. In addition to its theoretical significance, the satisfiability problem has numerous practical applications. SAT solvers are used in many engineering and scientific fields including circuit design and model checking. 
GridSAT is able to achieve new results by solving faster those problems that were previously solved by other solvers. Moreover, it was able to solve problems which were left unsolved by other solvers. GridSAT accomplishes these results by achieving two goals. The first is parallelizing the sequential solver in a manner which allows it to run efficiently on a large collection of resources. GridSAT also uses techniques to enable information sharing between the parallel components to avoid redundant work. The second goal is to design and implement the application so that it can adapt to the dynamic conditions of a computational grid environment. The techniques and design used to realize GridSAT can be deployed with other application to achieve new results. 
In addition, we show how multiple GridSAT instances can cooperate to run efficiently on a common set of resources without explicit synchronization. These experiments represent realistic scenarios where many grid applications share a common resource pool. 
We have also developed a web portal which accepts problem instances through a standard web browser and returns status and results while shielding users from complexities of running the application manually.

A comparative study of atorvastatin and rosuvastatin on lipid lowering efficacy in hyperlipidemic patients

The aim of the present study was to compare the lipid lowering effect of atorvastatin and rosuvastatin in patients (n=52) with hyperlipidemia. Patients were assigned to atorvastatin 10 mg or rosuvastatin 5 mg daily for 8 weeks. The blood was collected at baseline and after intervention to measure serum lipid profile. The level of serum total cholesterol in both atorvastatin and rosuvastatin groups was significantly reduced after intervention (p<0.00001 and p<0.00001 respectively) but no statistically significant difference (p=0.503) was observed between the two statin-treated groups. The reduction of serum triglyceride level was also significant (p=0.046 in atorvastatin group and p=0.0006 in rosuvastatin group). No significant difference was observed between the two groups (p=0.312). The serum LDL-C level was reduced significantly in both atorvastatin group (p<0.00001) and rosuvastatin group (p<0.00001). Again no statistically significant difference (p= 0.749) was observed between the two groups. No significant change was observed in the serum HDL level. Intergroup difference was not significant (p= 0.721). The present study indicates that, both atorvastatin and rosuvastatin improve the lipid profile but no significant change was observed between the two groups.

Genetic control of resistance to the aphid <i>Brevicoryne brassicae</i> in the wild species <i>Brassica fruticulosa</i>

Abstract Initial studies have shown variable resistance in Brassica fruticulosa to the aphid Brevicoryne brassicae The aim of this work was to fix high levels of resistance to B. brassicae in true breeding lines of B. fruticulosa and obtain data on the genetic control of resistance. Plants from initially variable B. fruticulosa accessions were selfed to produce inbred resistant and susceptible lines that were studied in three separate experiments to determine the extent to which resistance to B. brassicae had been fixed. Results from three experiments using successive generations of resistant and susceptible inbred lines showed that continued selection resulted in resistant inbred lines that supported an average of three aphids per plant compared with an average of 96 aphids per plant for susceptible inbred lines. Data collected from an experiment determining the resistant phenotype of lines including the selfed progenies and the F 1 and F 2 progeny of a cross between resistant and susceptible individual plants indicated that the resistance was not controlled by a single gene.

On using the adaptive delay filter in sparse identification and extensions to sparse deconvolution and sinusoid detection

The drawbacks of using the adaptive delay filter for plant identification are discussed. These drawbacks are due to regression and gain estimation errors and the filter's limitations under colored excitation hypotheses. After proposing simple solutions for both drawbacks, the authors show how the limitations can be solved by using different known techniques, such as dynamic programming or by applying adaptively thresholded gradient-type algorithms. The direct use of the latter algorithms is also presented as an alternative. Some simulation results illustrate the behaviour of the proposed modifications and extensions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Two-Step Identification of Instantaneous Cutting Force Coefficients and Cutter Runout

Cutting force coefficients and cutter runout parameters are the key factors for accurate prediction of instantaneous milling forces. A new two-step identification method is presented to calibrate them in end milling. Based on analyzing effects of cutter runout on milling forces, a method of extracting nominal milling forces from measured milling forces is proposed. By calibrating average cutting force coefficients and corresponding average chip thickness, an approach to evaluate the instantaneous cutting force coefficients is proposed. Then, an iterative method is presented to identify cutter runout, and the procedure is also given in detail. Milling tests are performed to test the proposed method, and validity of the identification approach is proved by a good agreement between predicted results and experimental results.

Supporting learning through tagging systems

With the advent of Web 2.0, new kinds of tools became available, which are not seen as novel anymore but are widely used. For instance, according to Eurostat data, in 2010 32% of individuals aged 16 to 74 used the Internet to post messages to social media sites or instant messaging tools, ranging from 17% in Romania to 46% in Sweden (Eurostat, 2012). Web 2.0 applications have been used in technology-enhanced learning environments. Learning 2.0 is a concept that has been used to describe the use of social media for learning. Many Learning 2.0 initiatives have been launched by educational and training institutions in Europe. Web 2.0 applications have also been used for informal learning. Web 2.0 tools can be used in classrooms, virtual or not, not only to engage students but also to support collaborative activities. Many of these tools allow users to use tags to organize resources and facilitate their retrieval at a later date or time. The aim of this chapter is to describe how tagging has been used in systems that support formal or informal learning and to summarize the functionalities that are common to these systems. In addition, common and unusual tagging applications that have been used in some Learning Objects Repositories are analysed.

Understanding solid nitrogen through machine learning simulation

We construct a fast, transferable, general purpose, machine-learning interatomic potential suitable for large-scale simulations of $N_2$. The potential is trained only on high quality quantum chemical molecule-molecule interactions, no condensed phase information is used. The potential reproduces the experimental phase diagram including the melt curve and the molecular solid phases of nitrogen up to 10 GPa. This demonstrates that many-molecule interactions are unnecessary to explain the condensed phases of $N_2$. With increased pressure, transitions are observed from cubic ($α-N_2$), which optimises quadrupole-quadrupole interactions, through tetragonal ($γ-N_2$) which allows more efficient packing, through to monoclinic ($λ-N_2$) which packs still more efficiently. On heating, we obtain the hcp 3D rotor phase ($β-N_2$) and, at pressure, the cubic $δ-N_2$ phase which contains both 3D and 2D rotors, tetragonal $δ^\star-N_2$ phase with 2D rotors and the rhombohedral $ε-N_2$. Molecular dynamics demonstrates where these phases are indeed rotors, rather than frustrated order. The model does not support the existence of the wide range of bondlengths reported for the complex $ι-N_2$ phase. The thermodynamic transitions involve both shifts of molecular centres and rotations of molecules. We simulate these phase transitions between finding that the onset of rotation is rapid whereas motion of molecular centres is inhibited and the cause of the observed sluggishness of transitions. Routine density functional theory calculations give a similar picture to the potential.

A novel biological function of alginate in Pseudomonas aeruginosa and its mucoid mutants: stimulation of exolipase

Treatment of Pseudomonas aeruginosa ATCC9027 with various commercial alginates from brown algae enhanced extracellular lipase activities in a time- and concentration-dependent manner (“exolipase stimulation”). Alginate isolated from Azotobacter vinelandii and mucoid mutants of P. aeruginosa was similarly effective. Several independently isolated mucoid (alginate-producing) mutants of P. aeruginosa showed higher spontaneous exolipase activities than the nonmucoid wild type. Alginate was chemically modified by (i) reduction of carboxyl groups (removal of charge), (ii) oxidation of pyranoid rings (destruction of tertiary structure), and (iii) reduction of reducing end groups. None of the chemical modifications resulted in total loss of the exolipase-stimulating ability of the alginate derivatives.

Branch prediction related Optimizations for Multithreaded Processors

Major chip manufacturers have all introduced Multithreaded processors. These processors are used for running a variety of workloads. Efficient resource utilization is an important design aspect in such processors. Depending on the workload, mis-speculated execution can severely impact resource utilization and power utilization. In general, compared to a uniprocessor, a multithreaded processor may have better tolerance towards mis-speculation. However there can still be phases where even a multi-threaded processor performance may get impacted by branch induced mis-speculation. In this paper I propose monitoring the branch predictor behavior of various hardware threads running on the multi-threaded processor and use that information as a feedback to the thread arbiter/picker which schedules the next thread to fetch instructions from. If I find that a particular thread is going through a phase where it is consistently mis-predicting its branches and its average branch misprediction stall is above a specific threshold then I temporarily reduce the priority for picking that thread. I do a qualitative comparison of various solutions to the problem of resource inefficiency caused due to mis-speculated branches in multithreaded processors. This work can be extended by doing a quantitative evaluation.

Critical Light Intensities for<i>Microcystis aeruginosa, Scenedesmus quadricauda</i>and<i>Cyclotella</i>sp. and Competitive Growth Patterns under Different Light:N:P Ratios

ABSTRACT ABSTRACT Critical light intensities for Microcystis aeruginosa, Scenedesmus quadricauda, and Cyclotella sp. were calculated, and patterns of growth and competition were analyzed under different light:N:P conditions in the laboratory. The growth of all three species was limited at a light intensity of 14 μmol.m−2.s-1, M. aeruginosa was in general the dominant competitor. At a light intensity of 54 μmol.m−2.s-1, N:P was the key factor controlling the competitive outcome. When light intensity was 108 μmol.m−2.s-1, light controlled the competitive outcome. Under constant light intensity conditions, S. quadricauda attained dominance only at low N:P ratios and moderate light intensity conditions. M. aeruginosa dominated under critical light intensity, moderate or high N:P ratio, or high light intensity. Under conditions of fluctuating light intensity, the densities of M. aeruginosa, S. quadricauda, and Cyclotella sp. in monoculture and mixed culture were lower than those under conditions of constant light intensity.
