Mid-infrared (~2.8 μm to ~7.1 μm) interband cascade lasers (2015)

20 years after their first reference interband cascade lasers (ICLs) have become a mature and competitive semiconductor laser source in the mid-infrared region. The carrier rebalancing concept that was introduced in 2011 drastically improved the performance. As a consequence the wavelength window that is accessible for ICLs operating at ambient temperatures could be extended. For GaSb based ICLs continuous wave (cw) emission at room temperature could be achieved up to a wavelength of 5.6 μm. As the need for thicker claddings at longer wavelengths makes the growth of the superlattice claddings increasingly difficult and limits the heat dissipation, a plasmon waveguide structure with highly doped InAslayers grown on InAs-substrates is typically used for ICLs emitting up to ~7 μm in pulsed mode at room temperature. With regard to the short wavelength limit of ICLs, we present cw emission of a GaSb based ICL emitting at 2.8 μm and with regard to the long wavelength limit we present room temperature pulsed operation of an InAs based plasmonic waveguide ICL up to 7.1 μm. Furthermore, we show single mode emitting ICLs with distributed feedback gratings emitting between 2.8 and 5.2 μm.

Regulation of insulin receptor substrate-1 in liver and muscle of animal models of insulin resistance. (1992)

Insulin rapidly stimulates tyrosine phosphorylation of a protein of approximately 185 kD in most cell types. This protein, termed insulin receptor substrate-1 (IRS-1), has been implicated in insulin signal transmission based on studies with insulin receptor mutants. In the present study we have examined the levels of IRS-1 and the phosphorylation state of insulin receptor and IRS-1 in liver and muscle after insulin stimulation in vivo in two rat models of insulin resistance, i.e., insulinopenic diabetes and fasting, and a mouse model of non-insulin-dependent diabetes mellitus (ob/ob) by immunoblotting with anti-peptide antibodies to IRS-1 and anti-phosphotyrosine antibodies. As previously described, there was an increase in insulin binding and a parallel increase in insulin-stimulated receptor phosphorylation in muscle of fasting and streptozotocin-induced (STZ) diabetic rats. There was also a modest increase in overall receptor phosphorylation in liver in these two models, but when normalized for the increase in binding, receptor phosphorylation was decreased, in liver and muscle of STZ diabetes and in liver of 72 h fasted rats. In the hyperinsulinemic ob/ob mouse there was a decrease in insulin binding and receptor phosphorylation in both liver and muscle. The tyrosyl phosphorylation of IRS-1 after insulin stimulation reflected an amplification of the receptor phosphorylation in liver and muscle of hypoinsulinemic animals (fasting and STZ diabetes) with a twofold increase, and showed a significant reduction (approximately 50%) in liver and muscle of ob/ob mouse. By contrast, the levels of IRS-1 protein showed a tissue specific regulation with a decreased level in muscle and an increased level in liver in hypoinsulinemic states of insulin resistance, and decreased levels in liver in the hyperinsulinemic ob/ob mouse. These data indicate that: (a) IRS-1 protein levels are differentially regulated in liver and muscle; (b) insulin levels may play a role in this differential regulation of IRS-1; (c) IRS-1 phosphorylation depends more on insulin receptor kinase activity than IRS-1 protein levels; and (d) reduced IRS-1 phosphorylation in liver and muscle may play a role in insulin-resistant states, especially of the ob/ob mice.

Effect of ethacrynate sodium on transmesothelial transfer of solutes. (1984)

The effect of ethacrynate sodium on transmesothelial fluxes of solutes was studied in vitro. Ethacrynate sodium increased the mesothelial permeability to urea, chloride and sodium. The increase was transient, reproducible and not dependent on cellular metabolism.
Catecholamine content of the cat nicitating membrane following procedures sensitizing it to norepinephrine. (1962)

The effect of denervation, decentralization and reserpinization on the catecholamine content (norepinephrine and epinephrine) and sensitivity of the smooth muscles of the nictitating membrane of the cat was Studied. Catecholamine content of superior cervical ganglia was also determined following decentralization and reserpinization. The predominant catecholamine in nictitating membrane and superior cervical ganglion was norepinephrine. Epinephrine concentration was only a few per cent of that of norepinephrine in both tissues. A precipitous fall of about 95% in catecholamine content of the nictitating membrane occurred between the twenty-fourth and thirty-sixth hour after removal of time superior cervical ganglion. Two weeks after denervation the content was essentially zero and no recovery was observed up to 105 days. Denervation increased sensitivity of the membrane to exogenous norepinephrine 200- to 300-fold. Reserpine (1 mg/kg intraperitoneally) reduced norepinephrine content of the nictitating membrane by about 98% within 24 hours after injection and increased sensitivity to norepinephrine only about 2-fold. Essentially full recovery of norepinephrine content was observed 21 days after treatment. Decentralization did not affect the norepinephrime content of nictitating membranes but increased sensitivity to norepinephrine 10- to 15-fold. Decentralization appeared to increase the norepinephrine content of superior cervical ganglia. Decentralization did not appreciably interfere with either the depletion of catecholamine stores by reserpine in membranes or ganglia, or the time for recovery of such stores following treatment with reserpine. Certain current hypotheses concerning the cause of supersensitivity in the nictitating membrane are discussed in relation to the data obtained in this study, and none appears to be completely satisfactory. An hypothesis is put forward based on the concept that normal post-ganglionic adrenergic nerve terminals possess a very efficient mechanism for removing norepinephrine, and thus limit the concentration of this substance reaching adrenergic receptors of effector cells. It is proposed that binding of norepinephrine at specific sites is tile initial step in this removal mechanism.
Central muscarinic activation elicits compulsive drinking behaviour in the rat (1987)

Injection of bethanechol into the lateral cerebral ventricle of the rat induces a marked increase in drinking, within 30 min from administration. The response is dose-related, maximal water intake (6.1 +/- 0.55 mL; mean +/- s.e.) occurring at 10 micrograms of bethanechol. Peripheral administration of the agonist (up to 3 mg kg-1 i.p.) fails to elicit drinking. Among several specific antagonists only antimuscarinic drugs produced a significant inhibition of the response, suggesting that the compulsive drinking behaviour in the rat is caused by activation of central muscarinic receptors. The drinking behaviour emerges as a reliable test to assess central muscarinic activity of both agonists and antagonists.
Phylogenetic position of the spirochetal genus Cristispira (1996)

Comparative sequence analysis of 16S rRNA genes was used to determine the phylogenetic relationship of the genus Cristispira to other spirochetes. Since Cristispira organisms cannot presently be grown in vitro, 16S rRNA genes were amplified directly from bacterial DNA isolated from Cristispira cell-laden crystalline styles of the oyster Crassostrea virginica. The amplified products were then cloned into Escherichia coli plasmids. Sequence comparisons of the gene coding for 16S rRNA (rDNA) insert of one clone, designated CP1, indicated that it was spirochetal. The sequence of the 16S rDNA insert of another clone was mycoplasmal. The CP1 sequence possessed most of the individual base signatures that are unique to 16S rRNA (or rDNA) sequences of known spirochetes. CP1 branched deeply among other spirochetal genera within the family Spirochaetaceae, and accordingly, it represents a separate genus within this family. A fluorescently labeled DNA probe designed from the CP1 sequence was used for in situ hybridization experiments to verify that the sequence obtained was derived from the observed Cristispira cells.
The Protein Interaction Network of the Human Transcription Machinery Reveals a Role for the Conserved GTPase RPAP4/GPN1 and Microtubule Assembly in Nuclear Import and Biogenesis of RNA Polymerase II (2010)

RNA polymerase II (RNAPII), the 12-subunit enzyme that synthesizes all mRNAs and several non-coding RNAs in eukaryotes, plays a central role in cell function. Although multiple proteins are known to regulate the activity of RNAPII during transcription, little is known about the machinery that controls the fate of the enzyme before or after transcription. We used systematic protein affinity purification coupled to mass spectrometry (AP-MS) to characterize the high resolution network of protein interactions of RNAPII in the soluble fraction of human cell extracts. Our analysis revealed that many components of this network participate in RNAPII biogenesis. We show here that RNAPII-associated protein 4 (RPAP4/GPN1) shuttles between the nucleus and the cytoplasm and regulates nuclear import of POLR2A/RPB1 and POLR2B/RPB2, the two largest subunits of RNAPII. RPAP4/GPN1 is a member of a newly discovered GTPase family that contains a unique and highly conserved GPN loop motif that we show is essential, in conjunction with its GTP-binding motifs, for nuclear localization of POLR2A/RPB1 in a process that also requires microtubule assembly. A model for RNAPII biogenesis is presented.
Geologically constrained migration velocity analysis (2000)

In the treatment of patients with cheilognathouranoschisis, rhinoplasty is a great challenge, since the cleft lip and palate will also produce nasal deformation requiring surgical correction. Unilateral cleft lip and palate is usually associated with a pronounced septal deformity resulting in "crooked nose" as well as typical asymmetry of the apex of the nose and of the nasal vestibule. The anterior part of the septum is dislocated in the direction of the unaffected side and the lower border of the septum is at the same time subluxated to the opposite side. The dorsal part of the septum presents with a convex deformity towards the cleft side extending in horizontal and vertical direction. Severe septal deformities cannot usually be adequately corrected on the spot, i.e. loco, but since septal correction is of paramount importance for the appearance and functioning of the nose we performed an extracorporeal correction of the septum in 191 cleft patients during the period from January 1980 through May 1993. Another characteristic feature of the cleft nose is the oblique modiolus, or columella cochleae, which is shortened on the cleft side, and the S-shaped deformity of the lateral alar cartilage, which presents with a cranial dislocation in the dome, caudal deviation in the lateral part, and an overhanging ala. After correction of the entire cartilaginous nasal framework the surgeon is usually confronted with asymmetry of the soft tissue. Satisfactory correction can be achieved by means of a three-flap technique in the region of the modiolus, nasal ala and vestibular skin: A modiolus-based transpositional flap results in a symmetrical height of the modiolus.(ABSTRACT TRUNCATED AT 250 WORDS)

Validation study of the questionnaire assessing level of knowledge in the rescue personnel regarding warning signs installed on the heavy machines road transporting dangerous materials (2017)

Introduction: Given the increase of road transportation of dangerous materials, if an accident occurs, the first groups that present at the scene are rescue groups (emergency، red crescent and firefighters). The aim of this study was to investigate the validity and reliability of the questionnaire assessing level of knowledge in the rescue personnel regarding warning signs mounted on the road heavy machinery. Material and Method: Firstly, a multiple-choice questionnaire was designed using the literature and material safety data sheets (MSDS). Validity of the questionnaire was examined using the viewpoints of 10 experts. The reliability of the questionnaire was assessed using test-retest in 20 subjects of the rescue groups in two-week intervals. The cut point of the questionnaire was determined by the Receiver Operating Characteristic (ROC). Result: The mean of age and work experience of the participants was 32.42 ± 2.57 and 7.75 ± 2.70. The results of correlation between the questions of the test showed that Cronbach’s alpha is 0.708. Also, the stability and reliability of test scores over time showed that the correlation between the questions in the first and second series was significance at acceptable level (r=0.698 with P-value=0.012(. The best value of cut point in the questionnaire of knowledge in the rescue personnel as obtained 18.5, with the sensitivity of 60% and specificity of 50%. Conclusion: The validity and reliability of the knowledge assessment questionnaire in the rescue personnel were confirmed regarding the warning signs mounted on the road heavy machines; therefore, it can be used in the future studies.
Milliwatt power UV-A LEDs developed by using n-AlGaN superlattice buffer layers grown on AlN templates (2018)

Ultraviolet (UV)-A light-emitting diode (LED) light sources are strongly demanded for both medical and photochemical applications. In our previous report, we investigated the conventional n-AlGaN buffer layer (BL)-based UV-A LED devices and a very low output power was achieved. In this work, we aim for the suppression of vertically propagating threading dislocation densities (TDDs) in the n-AlGaN BL including the current spreading layer (CSL) by introducing Si-doped n-Al0.37Ga0.63N/n-Al0.27Ga0.73N superlattices (SLs) between the AlN template and n-AlGaN BL for the demonstration of 341 nm UV-A LEDs. When the conventional n-AlGaN BLs were replaced with n-AlGaN SL-based BLs (with a suitable number of periods up to ~70) in the UV-A multi-quantum wells, then the full width at half maximum of the x-ray rocking curves in the n-AlGaN CSL for the (0 0 0 2) and (10–12) planes, respectively, were reduced to 346 and 431 arcsec and the total TDDs were suppressed to approximately ~1 × 109 cm−2. Finally, when the conventional Ni (20 nm)/Au (150 nm) p-electrodes were replaced with new Ni (1 nm)/Mg (200 nm) p-electrodes in the n-AlGaN SL-based UV-A LEDs, the maximum output power was improved from 2.1 to 2.5 mW.

Numerisches Rechnen – wie es ist und wie es sein könnte<sup>*</sup> (Computer artihmetic – what it is and what it could be) (2008)

Die nachfolgende Abhandlung weist anhand einiger Beispiele auf offensichtliche Schwächen der heutigen Rechnerarithmetik und Programmiersprachen hin und zeigt deren Auswirkungen in der Numerik auf. Es wird dann ein Konzept angegeben, welches es erlaubt, diese Schwächen zu vermeiden. Dieses beruht auf einer neuen Definition der Rechnerarithmetik. Die neue Arithmetik wurde systematisch auf einem Kleinrechnersystem implementiert. Der Rechner verfügt über Programmpakete zur Lösung zahlreicher Probleme aus der numerischen Mathematik. Bei 12-stelliger Dezimalrechnung wird dabei die Lösung jeweils auf mindestens 11 Stellen genau in Schranken eingeschlossen. Der Rechner beweist zudem die Existenz und Eindeutigkeit der Lösung innerhalb der berechneten Schranken. Ist diese nicht gegeben, so stellt er dies fest.
Reliable State Feedback Control Synthesis For Uncertain Linear Systems (2003)

ABSTRACT This paper is concerned with the problem of designing reliable state‐ feedback control for a class of uncertain linear systems with norm bounded uncertainty. A procedure for designing reliable state‐feedback control is presented for the case of actuator faults that can be modeled by a scaling factor. In the design, the performance of the normal system (without fault) is optimized, as the considered system operates under the normal condition most of the time. In addition, when actuator faults occur, the closed‐loop system retains robust stability and satisfies a known quadratic performance bound. A numerical example is provided to illustrate the effectiveness of the proposed design method.

<title>Modal Noise In Multimode Optical Fibers</title> (1983)

A changing speckle pattern exists at the output of a multimode optical fiber if the optical source is sufficiently coherent. When spatial filtration (for example, at a misaligned connector) or polarization filtration (for example, in certain access couplers) occurs in the presence of such speckle, the optical signal power fluctuates; such fluctuations are called "modal noise." This paper reviews modal noise theory and experiment, including the prediction and measurement of the modal noise signal-to-noise ratio in the presence of spatial filtration and constrained total guided power. It also presents new results relating to modal noise effects in fiber branching devices such as star couplers, access couplers, and power dividers.
From information visualization to direct manipulation (2006)

Today's generic data management applications such as accounting, CRM or logging and tracking software, rely on form and menu based interfaces. These applications take only marginal advantage of current graphical user interfaces. This is because the data they handle does not have intrinsic visual representations upon which direct manipulation principles can be used. This article presents how we have extended an Information Visualization framework with generic data manipulation functions. These new data editing capabilities are tuned to take advantage of the characteristics of each view. They enable us to generalize the direct manipulation mechanisms to address many abstract data manipulation needs. In this article we present five uses of the features we have implemented and deduce a general workflow applicable to a variety of contexts. The workflow comprises three steps and five editing actions. The steps are: adjust view, select, and edit. The editing actions are: edit a value or group of values, clone objects, remove objects, add attributes, and remove attributes. The workflow provides complete editing access to table and hierarchical data structures using particularly terse interaction methods. It defines a general data editing model that enables powerful data manipulation tasks without requiring end-user programming or scripting.
The Role of Aryne Distortions, Steric Effects, and Charges in Regioselectivities of Aryne Reactions (2014)

The distortion/interaction model has been used to explain and predict reactivity in a variety of reactions where more common explanations, such as steric and electronic factors, do not suffice. This model has also provided new fundamental insight into regioselectivity trends in reactions of unsymmetrical arynes, which in turn has fueled advances in aryne methodology and natural product synthesis. This article describes a systematic experimental and computational study of one particularly important class of arynes, 3-halobenzynes. 3-Halobenzynes are useful synthetic building blocks whose regioselectivities have been explained by several different models over the past few decades. Our efforts show that aryne distortion, rather than steric factors or charge distribution, are responsible for the regioselectivities observed in 3-haloaryne trapping experiments. We also demonstrate the synthetic utility of 3-halobenzynes for the efficient synthesis of functionalized heterocycles, using a tandem aryne-trapping/cross-coupling sequence involving 3-chlorobenzyne.
A study of transfer switching for the purpose of fault detection in FRIENDS (2004)

Abstract The authors have proposed a new concept of a distribution system “Flexible, Reliable and Intelligent ENergy Delivery System (FRIENDS)” with intent to solve imminent operating problems faced by utilities in providing their customers with reliable supply of power at several levels of quality. The main idea of FRIENDS is to introduce new facilities, so‐called Quality Control Centers (QCCs), which are installed very close to the customers for the purpose of implementing multiple functions, such as Customized Power Quality Service. In addition, these QCCs form a network for energy and information transmission at a level below distribution substations. QCCs make it possible to frequently change configuration of the network depending on the system and load conditions. These frequent reconfigurations of the network require fast and reliable Transfer Switching in the QCCs to ease an effect on customers. The reconfiguration for the purpose of fault area isolation also requires a fast Fault Detection feature. This paper presents a new method for controlling Transfer Switching and a method of Fault Detection in order to realize a fast and reliable reconfiguration of QCC network in a normal state, as well as under fault conditions. This paper also analyzes the methods in terms of instantaneous values calculated by PSCAD/EMTDC. © 2004 Wiley Periodicals, Inc.
