Bacterial meningitis and brain abscess
No full textBacterial meningitis and brain abscess continue to cause significant morbidity and mortality in children and adults. This article reviews recent changes in the epidemiology caused by new immunisations; the clinical manifestations at different ages; advances in the understanding of the pathophysiology; and current treatment strategies including the use of adjunctive therapies such as corticosteroids
Correlation problems in evolutionary stochastic processess
No full textIn a previous contribution to these Proceedings (Ramakrishnan(1)) the concept of product density was introduced to describe the statistical distribution of a discrete number of particles in a continuous space E, corresponding to a single point t, where t is the parameter with respect to which the stochastic process evolves. This is extended to densities corresponding to n points on the t axis and correlation problems associated with these density functions are studied with particular reference to electron-photon cascades
Scientometric Portrait of Nobel Laureate Venkatraman Ramakrishnan
No full textThe study presents an analysis of 165 research papers by Nobel Laureate Venkatraman Ramakrishnan published during 1977 to 2019 in the diverse field of science such as Biochemistry, Genetics and Molecular Biology, Medicine, Chemistry, Neuroscience, Immunology and Microbiology, Physics and Astronomy, Engineering and Materials Science. The highest number of publications contributed during the 2nd and 4th decade with 49 (29.70%) papers each. His paper entitles “Structure of the 30s ribosomal subunit” got maximum 1560 citations. Kelley, A. C. Was the most collaborative author and Europe was the most dominant continent collaborating with 132 papers whereas the United States was the top collaborated country with 100 (60.61%) papers. In the context of authorship pattern Triple authored papers were dominated with 34 (20.61%) papers. Among the most funding Sponsored body Agouron Institute topped the list with 23 (13.94%) papers, on the other hand, The Medical Research Council Laboratory of Molecular Biology, United Kingdom was the most contributed affiliation with 91 (55.15%) papers. In term of most preferred source and the most preferred subject of publications were Science with 23 (13.94%) and Biochemistry, Genetics and Molecular Biology with 97 (58.79%) papers respectively
The Bloch-Wigner-Ramakrishnan polylogarithm function
No full textThe dilogarithm function Li\\sb 2(z)=\\sum\\sp∞\\sbn=1z\\sp n/n\\sp 2 (\\vert z\\vert lt;1) has many beautiful properties and plays a role in connection with problems in many parts of mathematics, most recently K-theory. This function cannot be extended in a one-valued way to the entire complex plane, but the modified function D(z)=\\cal I(Li\\sb 2(z)+\\log (1-z)\\log \\vert z\\vert) introduced by D. Wigner and S. Bloch can be extended as a continuous real-valued function on \\Bbb C which is real-analytic except at 0 and 1. For the higher polylogarithm functions Li\\sb m(z)=\\sum\\sp∞\\sbn=1z\\sp n/n\\sp m a similar one-valued modification D\\sb m(z) was defined in principle, but not written down in closed form or studied in detail, by D. Ramakrishnan. \\par In the present paper the function D\\sb m(z) is given explicitly and some of its properties are studied. It turns out that values of certain Kronecker double series related to special values of Hecke L-series for imaginary quadratic fields can be given in terms of the functions D\\sb m(z) (generalizing a result of S. Bloch involving D\\sb 2=D) and that the function D\\sb m is related to a certain Green's function for the quotient of the upper half-plane by the group of translations τ \\mapsto τ +n, n\\in \\Bbb Z. Most interestingly, a conjecture is presented according to which the value of the Dedekind zeta-function ζ\\sb F(s) as s=m for an arbitrary number field F and integer mgt;1 can be expressed in closed form in terms of finitely many values of D\\sb m(z) at arguments z\\in F

Transverse upper gracilis flap with implant in postmastectomy breast reconstruction: a case report.
No full textAutologous flaps can be used in combination with prosthesis in postmastectomy breast reconstruction. The deep inferior epigastric perforator
(DIEP) flap is considered the preferred choice among autologous tissue transfer techniques. However, in patients with a peculiar figure
(moderately large breasts and large thighs with flat stomach), who cannot use their abdominal tissue, the transverse upper gracilis
(TUG) flap with implant is investigated as a further option for breast reconstruction. This report presents a patient who underwent the
TUG flap plus implant reconstruction. A bilateral skin-sparing mastectomy was performed removing 340 g for each breast. The volume of
the TUG flaps was 225 g (left) and 250 g (right). Preoperative volumes were restored by placing under the TUG muscle a round textured
implant. No complications occurred during the postoperative period both in the recipient and donor site and the outcomes of the procedure
were good. In cases where the use of the DIEP flap is not possible because of past laparotomies or inadequate abdominal volume,
the TUG flap plus implant may be considered as a valid alternative
Internames: A name-to-name principle for the future Internet
No full textInformation Centric Networking (ICN), a novel network paradigm, places the focus on the content instead of the end-hosts. ICN addresses content by names instead of locations and can ease content retrieval and improve network efficiency. Ongoing work attempts to extend the use of ICN to scenarios such as real time communication, group communication, push services, and addresses the issue of migration from the current network and coexistence of different network paradigms. In this work, we argue that by extending the current design of ICN from a 'host-to-name' to a 'name-to-name' architecture, the utility and efficiency of ICN could be further increased. We propose Internames, an architectural framework in which names are used to identify all entities involved in communication: content, users, devices, logical points, and services. Internames is envisioned to be an overarching name-to-name communication primitive that is fully compatible with ICN principles, accommodates the coexistence (or gradual migration) of different network realms (e.g., IP, ICN, VANET) and is suitable for application scenarios where ICN is somehow limited by its reliance on a 'host-to-name' approach. In this paper, we provide early insights into the Internames architecture by leveraging on the work done by the research community and identify components and challenges that require more detailed investigation
