Automated Intrusion Detection Methods Using NFR (1999)

There is often the need to update an installed Intrusion Detection System (IDS) due to new attack methods or upgraded computing environments. Since many current IDSs are constructed by manual encoding of expert security knowledge, changes to IDSs are expensive and require a large amount of programming and debugging. We describe a data mining framework for adaptively building Intrusion Detection (ID) models specifically for use with Network Flight Recorder (NFR). The central idea is to utilize auditing programs to extract an extensive set of features that describe each network connection or host session, and apply data mining programs to learn rules that accurately capture the behavior of intrusions and normal activities. These rules can be used for misuse detection and anomaly detection. Detection models are then incorporated into NFR through a machine translator, which produces a working detection model in the form of N-Code, NFR's powerful filtering language.
Stroke Volume with Dynamic Cardiomyoplasty during Ventricular Fibrillation in the Acute Dog. (1994)

The objective of this study was to determine the pumping capability of dynamic cardiomyoplasty during induced ventricular fibrillation. In this acute study of 6 dogs, the pumping capability of the unconditioned left latissimus dorsi (LD) muscle (141 to 292 gm), wrapped around both ventricles, was investigated during induced ventricular fibrillation. Left-ventricular and femoral artery pressure, the ECG and aortic root flow velocity were monitored. Prior to inducing ventricular fibrillation, the ability of the unconditioned LD muscle to augment stroke volume (SV), was quantified as the area under the aortic flow-velocity record. The ventricles were then fibrillated and, after 10 sec, rhythmic 250 msec trains (1/sec) of stimuli (40/sec) were delivered to the thoracodorsal nerve to contract the LD muscle tetanically. In no case could dynamic cardiomyoplasty produce the same SV as when the ventricles were beating normally. In one animal, the SV attained two percent of the normal SV by 5 contractions; in another, the SV reached one percent by 25 contractions. In the remaining animals, the SV varied around 20% of the prefibrillation SV. By 90 contractions, the stroke volume was 10% of the prefibrillation value. The progressive decrease in SV was likely a consequence of LD muscle ischemia and fatigue, since the latissimus dorsi muscle provided low blood flow during the period of fibrillation.
Correlation of migration behavior in free‐flow zone electrophoresis and electrophoretic titration curve (1990)

The correlation of electrophoretic migration behavior in free-flow zone electrophoresis (FFZE) and electrophoretic titration curve (ETC) has been explored. It is shown that the ETC of a protein or a mixture of proteins can be used to predict the fraction numbers at which those proteins elute in a preparative scale FFZE experiment. The ETC is a quick and effective way to choose optimal buffer conditions in FFZE. FFZE is employed to determine the isoelectric points (pI) of proteins whose pIs lie beyond the range of IEF 3-9 gels. It is found that separations in FFZE are governed by the net surface charge of the proteins.
High-voltage vertical multijunction solar cell (1976)

The vertical multijunction solar cell with covering lens is a photovoltaic device which promises efficiencies greater than that predicted under ideal conditions for any other structure. The mathematical analysis presented here illustrates this statement. In addition the structure described here is capable of a high-voltage output for small solar cell dimensions, a feature which makes this device attractive for many applications where other designs are impractical. The analysis predicts the output short-circuit current, open-circuit voltage, maximum power, and an efficiency of 21% for a silicon homojunction solar cell.
Vasopressin and Oxytocin Receptors in the Central Nervous System (1996)

This review concentrates on the pharmacological properties and the regional distribution of the arginine vasopressin (AVP) and oxytocin (OT) receptors that are present in the central nervous system. Of particular interest are the kinetics and the pharmacological profiles of these receptors that resemble those present at the periphery. However, their transduction mechanisms need to be further investigated. This should be rendered easier by molecular biology technology. The current knowledge of the anatomical distribution of AVP and OT receptors in the brain is reviewed. Also of great interest for double labeling studies will be the receptor antibodies, now being developed. The existence of additional receptors (AVP4-9) is examined, and aspects of the regulation of the receptors' expression in relation to the age, the species, and the hormonal status or following injury are also discussed.

Tracheal Ring Herniation (2010)

Inspection bronchoscopy during percutaneous dilational tracheostomy has become the standard of care to reduce complications of the procedure. During bronchoscopy, anatomic defects can be visualized before performing the procedure. We describe a case of discovering herniated tracheal rings in preprocedure bronchoscopy and subsequent treatment of this rare finding.
Pharmacokinetics of Nicotine Tartrate after Single‐Dose Liquid Enema, Oral, and Intravenous Administration (1997)

Ulcerative colitis is predominantly a disease of nonsmokers, and transdermal nicotine is therapeutic but often results in adverse reactions. Colonic administration of nicotine tartrate as a liquid enema could decrease systemic nicotine absorption and adverse reactions. The purpose of the current study was to determine the bioavailability and pharmacokinetic parameters of nicotine after administration by hydrophilic liquid enema (acidic and basic), hydrophobic liquid enema (acidic and basic), and by oral and intravenous routes. Thirty healthy volunteers received 45 micrograms nicotine base/kg (as nicotine tartrate) in one of five formulations (each n = 6): hydrophilic acidic liquid enema, hydrophilic basic liquid enema, hydrophobic acidic liquid enema, hydrophobic basic liquid enema, and oral solution. All participants also received 15 micrograms nicotine base/kg (as nicotine tartrate) intravenously during a separate study period. Serum concentrations of nicotine were determined by gas chromatography with mass spectrometry. The mean (+/-SD) bioavailabilities of nicotine after administration in the liquid enema formulations (hydrophilic acidic 17 +/- 18%, hydrophilic basic 16 +/- 16%, hydrophobic acidic 25 +/- 17%, hydrophobic basic 15 +/- 12%) were similar to the bioavailability of nicotine after administration by oral solution (20 +/- 25%). The bioavailabilities of nicotine for all five nonintravenous formulations were significantly less than for intravenous nicotine (100%). Serum concentrations of nicotine did not predict adverse reactions. Nicotine tartrate administered as either a liquid enema or as an oral solution had low bioavailability and was well tolerated. The therapeutic potential of nicotine tartrate liquid enemas, which can potentially limit toxicity by local (colonic) delivery of high doses of nicotine should be investigated in patients with left-sided ulcerative colitis.
Origins and Properties of Dental, Thymic, and Bone Marrow Mesenchymal Cells and Their Stem Cells (2012)

Mesenchymal cells arise from the neural crest (NC) or mesoderm. However, it is difficult to distinguish NC-derived cells from mesoderm-derived cells. Using double-transgenic mouse systems encoding P0-Cre, Wnt1-Cre, Mesp1-Cre, and Rosa26EYFP, which enabled us to trace NC-derived or mesoderm-derived cells as YFP-expressing cells, we demonstrated for the first time that both NC-derived (P0- or Wnt1-labeled) and mesoderm-derived (Mesp1-labeled) cells contribute to the development of dental, thymic, and bone marrow (BM) mesenchyme from the fetal stage to the adult stage. Irrespective of the tissues involved, NC-derived and mesoderm-derived cells contributed mainly to perivascular cells and endothelial cells, respectively. Dental and thymic mesenchyme were composed of either NC-derived or mesoderm-derived cells, whereas half of the BM mesenchyme was composed of cells that were not derived from the NC or mesoderm. However, a colony-forming unit-fibroblast (CFU-F) assay indicated that CFU-Fs in the dental pulp, thymus, and BM were composed of NC-derived and mesoderm-derived cells. Secondary CFU-F assays were used to estimate the self-renewal potential, which showed that CFU-Fs in the teeth, thymus, and BM were entirely NC-derived cells, entirely mesoderm-derived cells, and mostly NC-derived cells, respectively. Colony formation was inhibited drastically by the addition of anti-platelet-derived growth factor receptor-β antibody, regardless of the tissue and its origin. Furthermore, dental mesenchyme expressed genes encoding critical hematopoietic factors, such as interleukin-7, stem cell factor, and cysteine-X-cysteine (CXC) chemokine ligand 12, which supports the differentiation of B lymphocytes and osteoclasts. Therefore, the mesenchymal stem cells found in these tissues had different origins, but similar properties in each organ.
Absorption of Acyclic Oxygen Compounds in the Vacuum Ultraviolet. II. Ethers (1959)

A fluorite prism vacuum spectrograph and a hydrogen lamp have been used to determine the 45 000- to 65 000-cm—1 absorption spectra of dimethyl ether, diethyl ether, divinyl ether, and 1,4-pentadiene in the vapor phase at 22°C.
Turkey, the Caspian Region, & the Clash of Civilizations (2006)

This paper argues that Turkey's contemporary role in the Caspian Sea region directly challenges Samuel P. Huntington's civilizational paradigm. While his work Clash of Civilizations and the Remaking of World Order (1996) is now a rather dated contribution to International Relations Theory, Huntington's ideas have continued to reverberate in the post-9/11 world. As the conflict between the US and the Islamic world drags on in Iraq and the Middle East, the allure of Huntingtonesque arguments may be all the stronger. 1 The civilization that most conforms to Huntington's paradigm is the Islamic civilization. Within the geographical area of this civilization, the Caspian Sea presents an ideal region for study. Historically, this region has been an arena for the struggles of major global powers. In the nineteenth century, this pattern of conflict was dubbed The Great Game. Russia, China, and the US constitute the global powers now engaged in this pattern of competition. Therefore, the region provides possible support for those who endorse a clash of civilizations paradigm. However, analysis of Turkey's interaction in this region undermines this case. Turkey is an historically integral part of the Islamic world and cannot easily be dismissed by Huntington as an anomaly. This paper employs historical event data analysis across global, regional, and state levels. The conclusion of this research is that Turkey's international relationships do not reflect a growing trend toward a clash of civilizations. This examination, then, may be a timely reminder that the civilization approach lacks utility in International Relations Theory.
Supramolecular Gel Control of Cisplatin Crystallization: Identification of a New Solvate Form Using a Cisplatin-Mimetic Gelator (2015)

A series of platinum based low-molecular-weight urea-based gelators C1, C2, and C3, mimicking the structure of the anticancer drug cisplatin has been synthesized, as part of the development of a targeted, supramolecular gel phase crystallization and polymorphism screening strategy. Morphological and rheological studies established that inclusion of a longer spacer between the urea and cisplatin-mimetic regions of the gelator (C3) resulted in optimal gelation performance. Interfacial crystallization of cisplatin in a gel–sol biphasic system has been employed to address the insolubility of the drug molecule in organic solvents. A new N,N-dimethylacetamide (DMA) solvate of cisplatin has been identified and a crystal habit modification of the known N,N-dimethylformamide (DMF) solvate form of cisplatin has been observed on crystallization of cisplatin in C3 gels prepared in xylenes. While both targeted and nontargeted gels resulted in the formation of the new DMA solvate, only the targeted C3 gel resulted in high-quality single crystal suitable for characterization by single crystal crystallography. The high crystal quality is attributed to a close match between the core geometry of C3 with that of cisplatin together with local order in the gel fibers of C3.
Style Transfer in Text: Exploration and Evaluation (2017)

Style transfer is an important problem in natural language processing (NLP). However, the progress in language style transfer is lagged behind other domains, such as computer vision, mainly because of the lack of parallel data and principle evaluation metrics. In this paper, we propose to learn style transfer with non-parallel data. We explore two models to achieve this goal, and the key idea behind the proposed models is to learn separate content representations and style representations using adversarial networks. We also propose novel evaluation metrics which measure two aspects of style transfer: transfer strength and content preservation. We access our models and the evaluation metrics on two tasks: paper-news title transfer, and positive-negative review transfer. Results show that the proposed content preservation metric is highly correlate to human judgments, and the proposed models are able to generate sentences with higher style transfer strength and similar content preservation score comparing to auto-encoder.

Abstract P4-04-01: Combination of intratumoral CpG with systemic anti-OX40 and anti-CTLA4 mAbs eradicates established triple negative breast tumors in mice (2012)

Abstract Background: Evidence is mounting across diverse datasets and scientific techniques implicating immune dysregulation in poor outcomes of high grade and/or triple negative breast cancers. A multimodal strategy to stimulate the immune system could be an effective therapeutic approach for breast cancer. CpG oligodeoxynucleotides are single-stranded DNA that stimulate dendritic cells and B cells by binding to Toll-like receptor 9 (TLR9). OX40 (CD134) is predominantly expressed on activated T cells and the binding of OX40 with an agonistic antibody (anti-OX40) leads to the proliferation and survival of T cells. Agonistic anti-OX40 antibodies can also reverse the suppressive effects of Treg cells. A third avenue is to target Cytotoxic T lymphocyte associated antigen (CTLA4), which plays a negative regulatory role in T cell activation and is also constitutively expressed on Treg cells. Blocking CTLA4 with an antagonistic antibody (anti-CTLA4) has been shown to enhance anti-tumor responses. In this study, we tested the combination of intratumoral (IT) CpG with systemic anti-OX40 plus anti-CTLA4 in a mouse model of triple negative breast cancer. Methods: 4T1, an aggressive, triple-negative mammary carcinoma, was implanted orthotopically into syngeneic BALB/C mice. Treatment was initiated when tumors were ∼0.5 cm in the largest dimension. Mice were divided into 8 groups. Various combinations of PBS control, CpG, taxol, and anti-OX40+anti-CTLA4 mAbs were tested (Tables 1 and 2). CpG, 100 µg, was injected IT for 5 consecutive days (days 1–5); Taxol, 16 mg/kg, was administered IP on day 1; anti-OX40 (400 µg) and anti-CTLA4 (100 µg) were given IP on days 1 and 5. Mice were sacrificed once tumors became ulcerated or reached a diameter &gt;2 cm. Results: As shown in Table 1, CpG alone, taxol alone, or the anti-OX40 + anti-CTLA4 combination each delayed the growth of established 4T1 tumors when compared to the untreated control group. However, the majority of the mice (except one in CpG treated group) died from tumor progression. The combination of CpG + anti-OX40 + anti-CTLA4 had the best anti-tumor effects, with 4 out of 5 mice having demonstrated complete regression of their tumors (Table 2). The addition of taxol to the combination of CpG + anti-OX40 + anti-CTLA4 did not improve the anti-tumor effect, and while there was a substantial delay in growth, only one animal achieved a complete regression. Conclusion: Our study demonstrated that the combination of IT CpG with systemic anti-OX40 + anti-CTLA4 mAbs can cure mice with established triple negative breast tumors, supporting the possibilities of applying immune modulation approach in human triple negative tumors. Studies are on-going to further dissect the immunological mechanisms involved. Citation Information: Cancer Res 2012;72(24 Suppl):Abstract nr P4-04-01.
Cell Therapy of Peripheral Arterial Disease (2013)

The age-adjusted prevalence of peripheral arterial disease in the US population was estimated to approach 12% in 1985, and as the population ages, the overall population having peripheral arterial disease is predicted to rise. The clinical consequences of occlusive peripheral arterial disease include intermittent claudication, that is, pain with walking, and critical limb ischemia (CLI), which includes pain at rest and loss of tissue integrity in the distal limbs, which may ultimately lead to amputation of a portion of the lower extremity. The risk factors for CLI are similar to those linked to coronary artery disease and include advanced age, smoking, diabetes mellitus, hyperlipidemia, and hypertension. The worldwide incidence of CLI was estimated to be 500 to 1000 cases per million people per year in 1991. The prognosis is poor for CLI subjects with advanced limb disease. One study of >400 such subjects in the United Kingdom found that 25% required amputation and 20% (including some subjects who had required amputation) died within 1 year. In the United States, ≈280 lower-limb amputations for ischemic disease are performed per million people each year. The first objective in treating CLI is to increase blood circulation to the affected limb. Theoretically, increased blood flow could be achieved by increasing the number of vessels that supply the ischemic tissue with blood. The use of pharmacological agents to induce new blood vessel growth for the treatment or prevention of pathological clinical conditions has been called therapeutic angiogenesis. Since the identification of the endothelial progenitor cell in 1997 by Asahara and Isner, the field of cell-based therapies for peripheral arterial disease has been in a state of continuous evolution. Here, we review the current state of that field.
Human papillomavirus 16 immortalization of normal human ectocervical epithelial cells alters retinoic acid regulation of cell growth and epidermal growth factor receptor expression. (1993)

Retinoids are potent regulators of epithelial cell growth and differentiation. Recently, they have been demonstrated to be effective in the treatment of preneoplastic cervical lesions in which human papillomavirus (HPV) is expressed. To better understand the mechanism of the antineoplastic effect of retinoic acid on HPV-positive cells, the effects of retinoic acid on both normal and HPV-immortalized human ectocervical epithelial cell growth, epidermal growth factor (EGF) receptor level, and EGF receptor function were investigated. Both HPV-immortalized cells (ECE16-1) and normal ectocervical cells (ECE cells) are growth stimulated by EGF. ECE16-1 but not normal ectocervical epithelial cells are growth inhibited by trans-retinoic acid which attenuates the stimulatory effect of EGF on ECE16-1 cell growth. Retinoic acid reduces both EGF binding and EGF receptor protein levels in ECE16-1 cells but not in normal ectocervical cells. The reduction in EGF receptor binding and receptor protein levels in ECE16-1 cells is not associated with the induced secretion of a soluble EGF receptor ligand, altered EGF receptor affinity, receptor internalization, or decreased receptor stability. Interestingly, the level of EGF receptors is consistently elevated in the ECE16-1 cell line as compared to normal ectocervical epithelial cells. Investigation of a second HPV-immortalized cell line (ECE16-D1) and two other HPV-positive cervical carcinoma cell lines revealed similar elevated EGF-binding capacity and regulation by retinoic acid. In contrast, two HPV-negative cervical carcinoma cell lines demonstrated various EGF-binding levels but demonstrated no significant loss of EGF binding following retinoic acid treatment. Other normal cells and an SV40 large T-antigen-immortalized foreskin keratinocyte cell line, KER-1, had EGF receptor levels similar to the normal ectocervical epithelial cells, and no regulation by retinoic acid was observed. These data indicate that HPV immortalization may increase EGF receptor levels in ectocervical cells, elevating their sensitivity to growth stimulation by EGF, and that retinoic acid can possibly attenuate this increased responsiveness to EGF.
Metals and free radicals in neurodegeneration (1994)

Substantial evidence has accumulated implicating metals and free radicals in the pathogenesis of the major neurodegenerative disorders (Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis). Metal-induced oxidant stress can damage critical biological molecules and initiate a cascade of events including mitochondrial dysfunction, excitotoxicity, and a rise in cytosolic free calcium, leading to cell death. In Parkinson's disease and Alzheimer's disease there is evidence of oxidative stress in affected brain regions, as indicated by increased metal accumulation (which promotes free radical formation), decreased antioxidant levels (which protect against free radical formation), and oxidative damage. Recently, studies of the familial form of amyotrophic lateral sclerosis have detected mutations in the gene that encodes superoxide dismutase, which is one of the body's primary oxidant defense mechanisms. Mice that are transfected with the human mutant superoxide dismutase gene develop an amyotrophic lateral sclerosis syndrome. These studies demonstrate that oxidant stress can initiate the development of a chronic progressive neurodegenerative disorder.
