A bstract In the context of the gauge coupling unification, we present a comprehensive analysis of the extensions of the Standard Model with vector-like fermions and scalars. We find 145 models that satisfy the unification condition, which are distinguishable by the number of new particles in the spectrum and by their transformation properties unde...

A bstract In light of null results from New Physics searches at the LHC, we look at unification of the gauge couplings as a model-building principle. As a first step, we consider extensions of the Standard Model with vector-like fermions. We present a comprehensive list of spectra that feature fermions in two distinct SU(3) C × SU(2) L× U(1) Y repr...

In light of null results from New Physics searches at the LHC, we look at unification of the gauge couplings as a model-building principle. As a first step, we consider extensions of the Standard Model with vector-like fermions. We present a comprehensive list of spectra that feature fermions in two distinct $SU(3)_C\times SU(2)_L\times U(1)_Y$ rep...

We present a Bayesian analysis of the implications for new physics in semileptonic \(b\rightarrow s\) transitions after including new measurements of \(R_K\) at LHCb and new determinations of \(R_{K^*}\) and \(R_{K^{*+}}\) at Belle. We perform global fits with 1, 2, 4, and 8 input Wilson coefficients, plus one CKM nuisance parameter to take into ac...

The recent measurement of $R_K$ at LHCb continues to support the hint of violation of lepton flavor universality. We perform a global fit for new physics in semileptonic $b\to s$ transitions using all the relevant data with a Bayesian analysis technique. We include new measurements of $R_K$ at LHCb and new determinations of $R_{K^*}$ and $R_{K^{*+}...

(Abstracted from J Perinatol 2018;38:233–239) The hippocampus region of the brain plays an important role in memory and learning and appears to show particular response to iron deficiency. In this study, the researchers evaluated brain-derived neurotrophic factor (BDNF) concentrations found in cord blood as well as the intracranial volumes of 70 si...

Objective: Perinatal iron deficiency may have deleterious consequences on fetal neural development. The present study was conducted to determine the effect of maternal iron deficiency anemia (IDA) on fetal hippocampal morphogenesis and production of brain-derived neurotrophic factor (BDNF). Study design: Seventy term, singleton neonates born to...

In previous chapters we laid out the framework to capture the body of knowledge for (a) determining the required risk resilience level for the business using the business engagement model; (b) identifying and developing a road map of secured business capabilities with the secured business model; and (c) assessing, planning, and enabling people, pro...

No organization wants to take unnecessary risk. No business leader wants to do anything intentionally that would negatively harm the organization or themselves. Every business leader is accountable for something specific that eventually contributes to desired business outcomes. Business leaders set the framework and direction for the team to do the...

Regardless of the industry and size of the organization, there is a fundamental shift within every business and operating model. Organizations are dependent on each other, requiring a much tighter, integrated, and timely flow of information. The type of information and with whom they share information will only expand with time. In the online world...

Seamless connectivity, personalized products and services, real-time collaboration and transactions, automation, predictive insight and actions, use of public or shared infrastructure – these are some of the transformations many organizations are exploiting or exploring to be competitive, productive, and responsive. No doubt, these transformations...

Considering that Information Security is, at best, a governance topic in the boardroom and the accountability is assigned to the IT department, the metrics for measuring security effectiveness, if any, are IT-centric and operational in nature in most organizations. Many of these metrics can be categorized into the following.

The objectives, the requirements, the plans – help us create a desire for change and define a direction, but they are not sufficient to ensure we get to our intended destination. Both the business engagement and secured business models are designed to guide business management in defining and justifying the outcomes, that is, what and why the organ...

There is hardly a day when information security is not occupying one of the top slots in the newswire. Each time there is a piece of bad news or a security outbreak, organizations are quick to announce initiatives related to information security, cybersecurity, hacking, malware, data loss prevention (DLP), personal data, identity, and access manage...

Proactively plan and manage innovation in your business while keeping operations safe and secure. This book provides a framework and practices to help you safeguard customer information, prevent unauthorized access, and protect your brand and assets. Securing company operations is a board-level discussion. Across all industries, companies are pour...
