Exertional Dizziness And Syncope Caused By Anomalous Left Coronary Artery Origin From The Right Sinus Of Valsalva, Walid S. Hassan, Walid A. Al-Habeeb, Fayez E. El-Shaer, Zohair Y. Al-Halees

Saudi Medical Journal

Coronary anomalies are generally rare, but has fascinating congenital cardiac disease entities, recognized in less than 1.3% of all coronary angiograms. Left coronary artery arising from right sinus of valsalva RSOV represents an extremely uncommon subtype. Initial presentations include chest pain, myocardial infarction, arrhythmias, sudden death, and rarely exertional syncope. We report a case of exertional dizziness and syncope, diagnosed to have anomalous origin of left main coronary artery from RSOV. Surgical intervention was curative.

How Cellular Movement Determines The Collective Force Generated By The Dictyostelium Discoideum Slug, J. C. Dallon, H. G. Othmer

Faculty Publications

How the collective motion of cells in a biological tissue originates in the behavior of a collection of individuals, each of which responds to the chemical and mechanical signals it receives from neighbors, is still poorly understood. Here we study this question for a particular system, the slug stage of the cellular slime mold Dictyostelium discoideum. We investigate how cells in the interior of a migrating slug can effectively transmit stress to the substrate and thereby contribute to the overall motive force. Theoretical analysis suggests necessary conditions on the behavior of individual cells, and computational results shed light on experimental …

A Review Of Antennas And Propagation For Mimo Wireless Communications, Michael A. Jensen, Jon W. Wallace

Faculty Publications

Multiple-input-multiple-output (MIMO) wireless systems use multiple antenna elements at transmit and receive to offer improved capacity over single antenna topologies in multipath channels. In such systems, the antenna properties as well as the multipath channel characteristics play a key role in determining communication performance. This paper reviews recent research findings concerning antennas and propagation in MIMO systems. Issues considered include channel capacity computation, channel measurement and modeling approaches, and the impact of antenna element properties and array configuration on system performance. Throughout the discussion, outstanding research questions in these areas are highlighted.

Role Of Tuberculosis Laboratories In Saudi Arabia. A Call To Implement Standardized Procedures, Sahal A. Al-Hajoj, Fahad A. Alrabiah

Saudi Medical Journal

There is no doubt that the laboratory is the backbone for the diagnosis of tuberculosis (TB). Only through testing in the laboratory can the physician confirm suspicion of TB despite any previous clinical and x-ray findings. Recent visits to several laboratories in the Kingdom of Saudi Arabia showed that some need considerable improvement. Unless there are standardized procedures to diagnose TB, and safety measures are implemented in all laboratories, it will be impossible to diagnose accurately and control TB. The laboratories should be redesigned to conform to international TB Diagnostic Centers, with well trained staff and proper safety procedures.

True Believers Or Moral Absolutists, Seow Hon Tan

Research Collection Yong Pung How School Of Law

The recent American presidential elections brought to the fore the question of what place moral values have in public decision-making when traditional moral values are not espoused by all in a pluralist society. Even if traditional values - seen as absolutist - are imposed on others through a democratic electoral process, that imposition, particularly in hot button issues like abortion and same-sex marriage, remains difficult to accept.

Sensory Hypoinnervation In Club Foot, M Ahmed, N Ahmed, K. M. Khan, Masood Umer, H. Rashid,, Pervaiz Hashmi

Department of Surgery Docs

Abstract

We have compared the density of nerve fibres in the synovium in club foot with that of specimens obtained from the synovium of the hip at operations for developmental dysplasia. The study focused on the sensory neuropeptides substance P; calcitonin gene-related peptide; protein gene product 9.5, a general marker for mature peripheral nerve fibres; and growth associated protein 43, a neuronal marker for new or regenerating nerve fibres. In order to establish whether there might be any inherent difference we analysed the density of calcitonin gene-related peptide-positive nerve fibres in the hip and ankle joints in young rats. Semi-quantitative …

Watching The Shop From The Front Seat: Determinants Of Venture Capitalists' Representation On The Board, Reddi Kotha, Eli Talmor

Research Collection Lee Kong Chian School Of Business

Oversight and involvement are essential for a venture capital firm to influence the destiny of the portfolio company. This paper focuses primarily on the venture capital firm’s decision to take a formal responsibility through joining the board. Our study uses a large sample of private British companies that received institutional investment between 1999 and 2002. We examine the determinants of board composition and board size. Contrary to common belief, only 30 % of the companies have any institutional investor (a “VC”) on board. The decision to take a formal board seat is based on the ability to make a contribution: …

Bankruptcy Law And Inefficient Entitlements, Irit Haviv-Segal

ExpressO

The question as to the justification of bankruptcy law remains unanswered. The literature tends to emphasize the conflict and inability to compromise between the different normative outlooks of the insolvency law system. A deeper reflection on the existing theories of bankruptcy law reveals, however, that all theories share the same starting point: All theories share the understanding that efficiency considerations justify the enforcement of contractual bankruptcy arrangements. When the social theories call for increased levels of coercion and redistribution, these theories rely on normative considerations of distributive justice and rehabilitation values. They by no means rely on efficiency grounds. This …

Seasonality Of Tuberculosis In India: Is It Real And What Does It Tell Us?, Lorna E. Thorpe, Thomas R. Frieden, Kayla F. Laserson, Charles Wells, Gulshan Khatri

Michigan Bovine Tuberculosis Bibliography and Database

India has a third of the world’s tuberculosis cases. Large-scale expansion of a national program in 1998 has allowed for population-based analyses of data from tuberculosis registries. We assessed seasonal trends using quarterly reports from districts with stable tuberculosis control programs (population 115 million). In northern India, tuberculosis diagnoses peaked between April and June, and reached a nadir between October and December, whereas no seasonality was reported in the south. Overall, rates of new smear-positive tuberculosis cases were 57 per 100 000 population in peak seasons versus 46 per 100 000 in trough seasons. General health-seeking behavior artifact was ruled …

The Yeast Rrna Biosynthesis Factor Ebp2p Is Also Required For Efficient Nuclear Division, Costin N. Ionescu, Sofia Origanti, Michael A. Mcalear

Biological Sciences Faculty Research and Publications

Molecular genetic analysis of the yeast Ebp2 protein has revealed that it is an essential, nucleolar protein that functions in the rRNA biosynthesis pathway. Temperature-sensitive ebp2-1 mutants are defective in the processing of the 27 SA precursor rRNA, and the point substitutions that disrupt this activity cluster towards the central, more highly conserved region of the Ebp2 protein. We report here that other ebp2 mutants exhibit deficiencies associated with defects in chromosome segregation. Yeast cells bearing a 50 amino acid C-terminal truncation allele (ebp2ΔC50) display a slow-growth phenotype and exhibit an increased percentage of cells with …

Valley Splitting In Low-Density Quantum-Confined Heterostructures Studied Using Tight-Binding Models, Timothy B. Boykin, Gerhard Klimeck, Mark Friesen, S. N. Coppersmith, Paul Von Allmen, Seungwon Lee, Fabiano Oyafuso

Other Nanotechnology Publications

A detailed study of reduced-basis tight-binding models of electrons in semiconducting quantum wells is presented. The focus is on systems with degenerate valleys, such as silicon in silicon germanium heterostructures, in the low-density limit, relevant to proposed quantum computing architectures. Analytic results for the bound states of systems with hard-wall boundaries are presented and used to characterize the valley splitting in silicon quantum wells. The analytic solution in a no-spin-orbit model agrees well with larger tight-binding calculations that do include spin-orbit coupling. Numerical investigations of the valley splitting for finite band offsets are presented that indicate that the hard-wall results …

Probe-Level Correction In Analysis Of Affymetrix Data, Fenghai Duan

Probability & Statistics Seminar

For some of Affymetrix GeneChips, it is necessary to correct the texture effect on the images before doing the common background subtraction and normalization. In this study, we explore a way to assess and correct the texture effect. Without this correction, we found that the texture effect affected the performance of the conventional approach in identification of significantly expressed genes. Furthermore, we found that treating probes as "subjects" in the same probe set and using repeated measures analysis can help remove the local artifacts from the residual images, which are commonly associated with conventional approaches. Finally, we also tried to …

Problems With The Dartmouth Wireless Snmp Data Collection, Tristan Henderson, David Kotz

Computer Science Technical Reports

The original Dartmouth wireless network study used SNMP to query the college's Cisco 802.11b access points. The perl scripts that performed the SNMP queries suffered from some problems, in that they queried inappropriate SNMP values, or misunderstood the meaning of other values. This data was also used in a subsequent analysis. The same scripts were used to collect data for a subsequent study of another wireless network. This document outlines these problems and indicates which of the data collected by the original scripts may be invalid.
