Integration of micro-contact enhanced thermoelectric cooler with a FEEDS manifold-microchannel system for cooling of high flux electronics (2017)

Two-phase microchannel cooling has demonstrated substantial performance enhancement for thermal management of high-power electronics, offering remarkable heat removal capability without imposing high pumping power penalties. However, similar to other bulk cooling methods, this method alone too has difficulty in addressing remediation of local hotspots. Thermoelectric coolers, on the other hand, are scalable and perfectly suited for localized cooling. Thus in this paper, we report our work on integration of a micro-contact enhanced TEC with FEEDS (thin-Film Evaporation and Enhanced fluid Delivery System) manifold-micro channel system. Combining these two thermal management schemes into a single system can provide effective heat removal over the entire electronic chip surface. Integration of these two methods, however, poses several challenges, including hermetic sealing, wiring of the TEC, excessive joule heating in electrical traces, and thermal/electrical short-circuits. Thus, the aim of this study was to integrate an optimized, 3 mm x 0.8 mm TEC into a FEEDS manifold-microchannel system to create a reliable high flux cooling mechanism on a silicon or silicon carbide chip for cooling of 5kW/cm2 hotspot and 1kW/cm2 background heat fluxes. The manufacturing, integration configuration, and assembly of the system are discussed in this paper. A numerical model of the system is built and simulated using the commercial finite-element analysis software ANSYS. Preliminary numerical results demonstrated that with 30 °C temperature rise at the SiC chip's background surface, less than 35 °C hotspot temperature rise with respect to the coolant fluid temperature (110 °C) can be achieved.
Hot Isostatic Pressed Gd<sub>2</sub>O<sub>2</sub>S:Pr, Ce, F Translucent Scintillator Ceramics for X-Ray Computed Tomography Detectors (1988)

Translucent scintillator ceramics of Gd 2 O 2 S:Pr, Ce, F were fabricated using a hot isostatic pressing (HIP) technique. The optical transmission is about 60% of the incident light and the X-ray stopping power is also quite high. Owing to the enhancement of these properties by the HIP densification process, the highest light output from a 1 mm thick specimen combined with a silicon photodiode, when excited by 120 kV X-rays, has reached 1.8 times that of CdWO 4 single crystals. The present ceramics are very promising candidates for scintillator materials in X-ray computed tomography (CT) detector applications.
Optimal Cross Slice Orchestration for 5G Mobile Services (2018)

5G mobile networks encompass the capabilities of hosting a variety of services such as mobile social networks, multimedia delivery, healthcare, transportation, and public safety. Therefore, the major challenge in designing the 5G networks is how to support different types of users and applications with different quality-of-service requirements under a single physical network infrastructure. Recently, network slicing has been introduced as a promising solution to address this challenge. Network slicing allows programmable network instances which match the service requirements by using network virtualization technologies. However, how to efficiently allocate resources across network slices has not been well studied in the literature. Therefore, in this paper, we first introduce a model for orchestrating network slices based on the service requirements and available resources. Then, we propose a Markov decision process framework to formulate and determine the optimal policy that manages cross-slice admission control and resource allocation for the 5G networks. Through simulation results, we show that the proposed solution is efficient not only in providing slice-as-a-service based on service requirements, but also in maximizing the provider's revenue.

Neural Models for Information Retrieval (2017)

Neural ranking models for information retrieval (IR) use shallow or deep neural networks to rank search results in response to a query. Traditional learning to rank models employ machine learning techniques over hand-crafted IR features. By contrast, neural models learn representations of language from raw text that can bridge the gap between query and document vocabulary. Unlike classical IR models, these new machine learning based approaches are data-hungry, requiring large scale training data before they can be deployed. This tutorial introduces basic concepts and intuitions behind neural IR models, and places them in the context of traditional retrieval models. We begin by introducing fundamental concepts of IR and different neural and non-neural approaches to learning vector representations of text. We then review shallow neural IR methods that employ pre-trained neural term embeddings without learning the IR task end-to-end. We introduce deep neural networks next, discussing popular deep architectures. Finally, we review the current DNN models for information retrieval. We conclude with a discussion on potential future directions for neural IR.

Attention deficit hyperactivity disorder : successful programs and approaches : an honors thesis (HONRS 499) (1998)

Today more and more children are being diagnosed with attention deficit hyperactivity disorder than ever before. It is estimated that one child in every classroom will have attention deficit hyperactivity disorder. With the increasing numbers of children being diagnosed it is extremely important that educators be well informed on the subject matter. This discussion of attention deficit hyperactivity disorder gives an in-depth look at successful programs, strategies, techniques, and treatments for a child with attention deficit hyperactivity disorder. It also briefly discusses common symptoms and causes of the disorder. Finally, there is a brief look at how attention deficit hyperactivity disorder effects adolescents and adults in our society.
HER2-Positive Circulating Tumor Cells in Breast Cancer (2011)

HER2-positive CTCs were detected in DCIS/LCIS or M0 BC irrespective of the primary tumor HER2 status. Nevertheless, their presence was more common in women with HER2-positive disease. Monitoring of HER2 expression on CTCs might be useful in trials with anti-HER2 therapies.
Line edge roughness frequency analysis for SAQP process (2016)

The line edge roughness (LER) and line width roughness (LWR) transfer in a self-aligned quadruple patterning (SAQP) process is shown for the first time. Three LER characterization methods, including conventional standard deviation method, power spectral density (PSD) method and frequency domain 3-sigma method, are used in the analysis. The wiggling is also quantitatively characterized for each SAQP step with a wiggling factor. This work will benefit both process optimization and process monitoring.
Wireless Network Emulation System (WiNE) (2005)

Abstract : Costly decisions about which wireless networking technologies to develop are currently being based largely on results from high-level simulation tools. The FCS-C program, for instance, used high-level simulation tools to select the network and radio software for final development and demonstration. To mitigate risk, there needs to be lab-based tools that provide more accurate assessment than simulation but at far less cost than field testing. Our approach to this problem is to develop a tool that emulates a field-test environment in the lab, so technologies under consideration can migrate from coarse simulation models to actual code and tested live, in real-time, over a high-fidelity virtual wireless channel environment. Our current solution is the Wireless Network Emulator (WiNE). This report summarizes the development and testing that was conducted under this program. Notable achievements include the development of the first integrated prototype of the embedded distributed simulation engine, accompanied by a wonderful graphical user interface; and the development of detailed network, traffic, mobility, and environment models patterned after the FCS-C baseline field tests conducted at the Naval base in Lakehurst, NJ. Future work under consideration includes improvements in platform stability, support for HLA, new simulation models (specifically underwater and hybrid sensor networks), expanding the library of propagation, radio, and MAC models, and the development of a diverse set of virtual worlds.
Isolation and identification of human hair ceramides (1995)

Synopsis The analysis of the lipids extracted from human hair by silica-gel-column liquid chromatography permitted an isolation of the fraction enriched in free ceramides. These were identified by GC/MS and are related to ceramide classes 2 and 5 in which the long-chain base was predominantly sphinganine. This differs from that observed in the free ceramides found within the stratum corenum.
The Corrosion Inhibition of Mild Steel in Sulphuric Acid Solution by Flavonoid (Catechin) Separated from Nypa Fruticans Wurmb Leaves Extract (2014)

The corrosion inhibition of mild steel in sulphuric acid by flavonoids, separated from Nypa fruticans Wurmb leaves extract was studied using weight loss technique at 303K, 313K, 323K, 333K and 353K,. The constituents were separated by fractionation using Soxhlet apparatus after room temperature extraction with 70% acetone. The constituents were identified using standard functional group analysis (phytochemical screening) methods. The inhibitor concentrations of 0.1 g/L, 0.2 g/L, 0.3 g/L, 0.4 g/L and 0.5 g/L were used in 0.1M, 0.5M, 1M and 2M concentrations of acid solutions. Inhibition efficiency increased with increase in temperature and inhibitor concentration. Thus, maximum inhibition efficiency of 74.48% was obtained at the optimum temperature (323K) and concentration (0.5 g/L) for the flavonoid constituent. The flavonoid (catechin) separated from Nypa fruticans Wurmb leaves extract were used separately as efficient corrosion inhibitor of mild steel in H2SO4.
Legalizing a Placement with Minimum Total Movement (2004)

Most tools for the placement of very large scale integrated chips work in two steps. First, the cells that have to be placed are roughly spread out over the chip area, ignoring disjointness (global placement). Then, in a second step, the cells are moved to their final position such that all overlaps are removed and all additional constraints are met (detailed placement or legalization). In this paper, we describe new ideas for legalization. We divide the task into appropriate subproblems that can be solved optimality in polynomial time. For the most important parts, even a linear running time can be shown. Together, the solutions of the subproblems can be combined to an algorithm that legalizes a placement minimizing the total (linear or squared) movement of cells. The algorithm is tested on a set of recent application specific integrated circuits and the results are compared to lower bounds showing that it computes provably good solutions (within a few percent of the optimum) even on very large industrial chips. By introducing significantly fewer violations, our legalization helps in overall design closure.
Altered Gene Expression Pattern in Peripheral Blood Mononuclear Cells in Patients with Acute Myocardial Infarction (2012)

In the acute phase of STEMI, dozens of genes from several pathways linked with lipid/glucose metabolism, platelet function and atherosclerotic plaque stability show altered expression. Up-regulation of SOCS3 and FAM20 genes in the first days of myocardial infarction is observed in the vast majority of patients.
Processing of Thermoplastic Polymers Using Reactive Solvents (1996)

The use of reactive solvents offers an interesting and flexible route to extend the processing characteristics of thermoplastic polymers beyond their existing limits. This holds for both intractable and tractable polymers. The first mainly applies for amorphous high- T g polymers where processing may be limited due to the high temperatures required which can cause problems related to degradation and where the solvent helps to decrease the processing temperature considerably. A prime example here can be found in the system poly(phenelyne–ether) PPE/epoxy. The second mainly holds for semicrystalline polymers and the attention here is focused on obtaining low viscosities in order to be able to apply alternative processing routes, like pouring or casting, for those polymers which are generally easy to process by more conventional techniques like injection moulding or extrusion. In this paper the model system poly(ethylene) PE/styrene is investigated. In both cases, based on intractable and tractable polymers, the solvent is polymerized after moulding, thus converting into a non-solvent, and becomes, after the concurrent phase separation and phase inversion, an integral and often structural part of the final product. Interestingly, specific morphologies, in terms of the size of the dispersed (previous solvent) phase formed or the position and thickness of in situ formed interlayers when polymerization occurs in the presence of a polar surface, can be obtained which can otherwise extremely difficult, or not at all, be realized. Moreover, flexibility of the choice of the reactive solvent creates tuneable mechanical (and, if requested, other) properties of those phases, varying from glassy, with a T g of typically 200°C, to complete rubbery, with a T g far below room temperature. Of course a disadvantage of the technique is that a polymerization step must occur after the shaping process. Compared to more standard reactive processing techniques, however, clear advantages can exist with respect to the occurrence of early vitrification—yielding a fast demoulding possibility—induced by the reaction induced phase separation, and the fact that the continuous thermoplast phase ultimately determines the main product properties, including the possibility of second-stage deformability and reprocessability.
Identical mutations in unrelated families with generalized resistance to thyroid hormone occur in cytosine-guanine-rich areas of the thyroid hormone receptor beta gene. Analysis of 15 families. (1993)

Generalized resistance to thyroid hormone (GRTH) is a syndrome of variable reduction of tissue responsiveness to thyroid hormone. 28 different point mutations in the human thyroid hormone receptor beta (TR beta) gene have been associated with GRTH. These mutations are clustered in two regions of the T3 binding domain of the TR beta (codons 310-347 and 417-453). We now report point mutations in the TR beta gene of six additional families with GRTH and show that three mutations occurred each in three families with GRTH, and that three other mutations were each present in two families. In 11 of these 15 families, lack of a common ancestor could be confirmed by genetic analysis. 28 of the 38 point mutations so far identified, including all those occurring in more than one family, are located in cytosine-guanine-rich areas of the TR beta gene. Differences in clinical and laboratory findings in unrelated families harboring the same TR beta mutation suggest that genetic variability of other factors modulate the expression of thyroid hormone action.
Interaction of profilin‐1 and F‐actin via a β‐arrestin‐1/JNK signaling pathway involved in prostaglandin E<sub>2</sub>‐induced human mesenchymal stem cells migration and proliferation (2010)

Although many previous reports have examined the function of prostaglandin E(2) (PGE(2)) in the migration and proliferation of various cell types, the role of the actin cytoskeleton in human mesenchymal stem cells (hMSCs) migration and proliferation has not been reported. The present study examined the involvement of profilin-1 (Pfn-1) and filamentous-actin (F-actin) in PGE(2)-induced hMSC migration and proliferation and its related signal pathways. PGE(2) (10(-6) M) increased both cell migration and proliferation, and also increased E-type prostaglandin receptor 2 (EP2) mRNA expression, β-arrestin-1 phosphorylation, and c-Jun N-terminal kinase (JNK) phosphorylation. Small interfering RNA (siRNA)-mediated knockdown of β-arrestin-1 and JNK (-1, -2, -3) inhibited PGE(2)-induced growth of hMSCs. PGE(2) also activated Pfn-1, which was blocked by JNK siRNA, and induced F-actin level and organization. Downregulation of Pfn-1 by siRNA decreased the level and organization of F-actin. In addition, specific siRNA for TRIO and F-actin-binding protein (TRIOBP) reduced the PGE(2)-induced increase in hMSC migration and proliferation. Together, these experimental data demonstrate that PGE(2) partially stimulates hMSCs migration and proliferation by interaction of Pfn-1 and F-actin via EP2 receptor-dependent β-arrestin-1/JNK signaling pathways.
Estimation of attraction domains in wheeled robot control (2006)

Considered is the control design problem for planar motion of a wheeled robot. The mathematical model of the robot accounts for kinematic relationships between the velocity of a given point of chassis referred to as the reference point, orientation of the chassis, and control. Among the kinematic relations is the requirement that each of the four wheels perform a slip-free motion. The rear wheels are assumed to be driving while the front wheels are responsible for the rotation of the chassis. The control objective is to place the reference point in the prespecified trajectory and to stabilize the motion of the reference point along the prespecified trajectory. The trajectory consists of line segments and circular arcs. In the mathematical model under consideration, the current curvature of the trajectory of the reference point is taken as control; it is related to the steering angle of the front wheels by a simple algebraic expression. The control is subject to two-sided constraints due to limitations on the steering angle of the front wheels. For the control law proposed, the attraction domain in the space “distance to the trajectory—orientation” is analyzed. For the initial conditions from this domain, the system is guaranteed to hit a trajectory with given index of exponential stability.
Absorption of Oligodeoxynucleotide by Suppository from Rat Rectal Route. (1997)

Rectal absorption of 32-mer phosphorothioate deoxynucleotides (S-Oligo) in the rat was attempted with the aid of a suppository containing oleic acid and a surfactant. Although, the suppository without adjuvant did not show detectable blood levels, that containing over 10% oleic acid enabled the absorption of S-Oligo with tmax at 2 h postdosing.
Central Pre-proglucagon Derived Peptides: Opportunities for Treatment of Obesity (2003)

Modern societies have moved from famine to feast and obesity and its co-morbidities now sweep the world as a global epidemic. Numerous scientific laboratories and pharmaceutical companies have taken the challenge and are now exploiting novel molecular targets for treatment of obesity. The pre-proglucagon system constitutes interesting candidates as potential targets for new anti-obesity drugs. In the periphery, pre-proglucagon derived peptides, Glucagon-Like Peptide-1 (GLP-1), Glucagon-Like Peptide-2 (GLP-2) and oxyntomodulin (OXM) are involved in a wide variety of physiological functions, including glucose homeostasis, gastric emptying, intestinal growth, insulin secretion as well as the regulation of food intake. Peripheral administration of GLP-1 derivatives and analogues to both rodents and man have shown promising effects on food intake and body weight suggesting that such therapies constitute potential anti-obesity treatment. In the central nervous system, pre-proglucagon and hence GLP-1, GLP-2 and OXM are exclusively found in a small population of nerve cells in the nucleus of the solitary tract. These constitute a neural pathway linking the "viscero-sensory" brainstem to hypothalamic nuclei involved in energy homeostasis. Intracerebroventricular administration of all of the three derived peptides robustly decrease food intake. It is evident that central GLP-1 agonism probably in combination with GLP-2 and/or OXM agonism constitute a potential pharmacological tool to reduce food intake and maybe also enhance energy expenditure. This and other aspects of the current state of the role of central pre-proglucagon in energy homeostasis are reviewed.
