Leadership Styles in India- An empirical Study of Indian Entrepreneurs/Leaders
The word Leader simply means a person who leads. A leader should necessarily possess the characteristics of organizing, staffing, training, motivating, recognizing the special capabilities and talents, setting standards, correcting deviations, achieving objectives etc. or by guiding his subordinates and showing the way to be followed in order to reach the organizational goal. Each and every person has to either lead or follow. This is decided on the basis of aptitude, potential and determination.Very few are daring and courageous enough to risk unpopularity by depending from the herd. The ability to make a spot decision is what differentiates the executive or leader from the clerk. A leader always exerts a positive influence on the life of others, as a member of team or the head of a small department. The role of an effective leader is value addition. Leadership is a multi-dimensional, multi-faceted, multi-situational and multi-role concept."Management is doing things right; leadership is doing the right things." There are nine key qualities that research shows people seek in a successful leader:Passion; Decisiveness; Conviction; Integrity; Adaptability; Emotional Toughness; Emotional Resonance; Self Knowledge; Humility This study intends to study various approaches to leadership adopted by entrepreneurs and leaders in India, specifically those in cities selected for the study. Effectively, the data were analysed and conclusions were drawn
Implementing and Characterizing Real-time Broadband RFI Excision for the GMRT Wideband Backend
The Giant Metrewave Radio Telescope (GMRT) is being upgraded to increase the
receiver sensitivity. This makes the receiver more susceptible to man-made
Radio Frequency Interference (RFI). To improve the receiver performance in
presence of RFI, real-time RFI excision (filtering) is incorporated in the GMRT
wideband backend (GWB). The RFI filtering system is implemented on FPGA and
CPU-GPU platforms to detect and remove broadband and narrowband RFI. The RFI is
detected using a threshold-based technique where the threshold is computed
using Median Absolute Deviation (MAD) estimator. The filtering is carried out
by replacing the RFI samples by either noise samples or constant value or
threshold. This paper describes the status of the real-time broadband RFI
excision system in the wideband receiver chain of the upgraded GMRT (uGMRT).
The test methodology for carrying out various tests to demonstrate the
performance of broadband RFI excision at the system level and on radio
astronomical imaging experiments are also described.Comment: 7 pages, 7 figure

The microbiome in patients with atopic dermatitis.
As an interface with the environment, the skin is a complex ecosystem colonized by many microorganisms that coexist in an established balance. The cutaneous microbiome inhibits colonization with pathogens, such as Staphylococcus aureus, and is a crucial component for function of the epidermal barrier. Moreover, crosstalk between commensals and the immune system is now recognized because microorganisms can modulate both innate and adaptive immune responses. Host-commensal interactions also have an effect on the developing immune system in infants and, subsequently, the occurrence of diseases, such as asthma and atopic dermatitis (AD). Later in life, the cutaneous microbiome contributes to the development and course of skin disease. Accordingly, in patients with AD, a decrease in microbiome diversity correlates with disease severity and increased colonization with pathogenic bacteria, such as S aureus. Early clinical studies suggest that topical application of commensal organisms (eg, Staphylococcus hominis or Roseomonas mucosa) reduces AD severity, which supports an important role for commensals in decreasing S aureus colonization in patients with AD. Advancing knowledge of the cutaneous microbiome and its function in modulating the course of skin disorders, such as AD, might result in novel therapeutic strategies
Evaluation of three different agents for in-office treatment of dentinal hypersensitivity: A controlled clinical study
Context: Dentin desensitizers are used for in-office treatment of dentinal hypersensitivity. They block the open tubules and bring about a reduction in hypersensitivity.
Aim: The aim was to evaluate and compare the clinical effectiveness of a dentin desensitizer, a combination of a dentin desensitizer + adhesive and one-bottle self-etching adhesive for in-office treatment of dentin hypersensitivity.
Settings and Design: Institutional, prospective double-blind parallel clinical design.
Subjects and Methods: A total of 54 teeth in 20 patients were randomly allocated to one of the three study groups, with 18 teeth in each group as follows: Group A-Gluma Desensitizer (GD), Group B-Gluma Comfort Bond + Desensitizer (GCBD), Group C-Single Bond Universal (SBU). The patients′ dentinal hypersensitivity scores for tactile (hand-held scratch device), thermal (cold), and evaporative (dental unit air syringe) stimuli were recorded on a visual analog scale. The parameters were recorded at baseline, immediately after application of the agent, 3- and 6-week posttreatment.
Statistical Analysis Used: The data were analyzed with Friedman′s test, Wilcoxon signed ranks test, Kruskal-Wallis test, and Mann-Whitney-U-test (P < 0.05).
Results: All three groups showed a significant reduction in dentinal hypersensitivity (P < 0.05) compared to baseline at all time intervals. Statistically, significant differences were noted between GD and SBU; between GCBD and SBU in all testing parameters. Between GD and GCBD no significant difference was noted.
Conclusions: GD and GCBD showed a greater reduction in dentin hypersensitivity than SB

Translation from unconventional 5′ start sites drives tumour initiation
We are just beginning to understand how translational control affects tumour initiation and malignancy. Here we use an
epidermis-specific, in vivo ribosome profiling strategy to investigate the translational landscape during the transition from
normal homeostasis to malignancy. Using a mouse model of inducible SOX2, which is broadly expressed in oncogenic
RAS-associated cancers, we show that despite widespread reductions in translation and protein synthesis, certain
oncogenic mRNAs are spared. During tumour initiation, the translational apparatus is redirected towards unconventional
upstream initiation sites, enhancing the translational efficiency of oncogenic mRNAs. An in vivo RNA interference screen
of translational regulators revealed that depletion of conventional eIF2 complexes has adverse effects on normal but not
oncogenic growth. Conversely, the alternative initiation factor eIF2A is essential for cancer progression, during which
it mediates initiation at these upstream sites, differentially skewing translation and protein expression. Our findings
unveil a role for the translation of 5′ untranslated regions in cancer, and expose new targets for therapeutic intervention
