Rapid Crystallization of All-Inorganic CsPbBr3 Perovskite for High-Brightness Light-Emitting Diodes (2017)

Research into perovskite-based light-emitting diodes (PeLEDs) has been rapidly gaining momentum since the initial reports of green-emitting methylammonium lead bromide (CH<sub>3</sub>NH<sub>3</sub>PbBr<sub>3</sub>)-based devices were published. However, issues pertaining to its stability and morphological control still hamper progress toward high performing devices. Solvent engineering, a technique typically employed to modulate film crystallization, offers little opportunity for scale-up due to the tendency for inhomogeneous film growth and low degree of reproducibility. Here, we propose and show a simple gas-facilitated process to deposit a stable, all-inorganic perovskite CsPbBr<sub>3</sub> film. The formation of smaller and less percolated grains, which gives rise to enhanced optical properties, highlights the importance of spatial charge confinement in the film. Consequently, the performance of our PeLEDs shows great improvement, with luminance as high as 8218 cd m<sup>-2</sup> and turn-on voltage as low as 2.4 V. Concomitantly, the current efficiency and EQE of our device were increased to 0.72 cd A<sup>-1</sup> and 0.088%, respectively. High reproducibility in the performance of PeLEDs fabricated using this process opens the path for large-area devices.
Human milk lactoferrin inactivates two putative colonization factors expressed by Haemophilus influenzae (1998)

Haemophilus influenzae is a major cause of otitis media and other respiratory tract disease in children. The pathogenesis of disease begins with colonization of the upper respiratory mucosa, a process that involves evasion of local immune mechanisms and adherence to epithelial cells. Several studies have demonstrated that human milk is protective against H. influenzae colonization and disease. In the present study, we examined the effect of human milk on the H. influenzae IgA1 protease and Hap adhesin, two autotransported proteins that are presumed to facilitate colonization. Our results demonstrated that human milk lactoferrin efficiently extracted the IgA1 protease preprotein from the bacterial outer membrane. In addition, lactoferrin specifically degraded the Hap adhesin and abolished Hap-mediated adherence. Extraction of IgA1 protease and degradation of Hap were localized to the N-lobe of the bilobed lactoferrin molecule and were inhibited by serine protease inhibitors, suggesting that the lactoferrin N-lobe may contain serine protease activity. Additional experiments revealed no effect of lactoferrin on the H. influenzae P2, P5, and P6 outer-membrane proteins, which are distinguished from IgA1 protease and Hap by the lack of an N-terminal passenger domain or an extracellular linker region. These results suggest that human milk lactoferrin may attenuate the pathogenic potential of H. influenzae by selectively inactivating IgA1 protease and Hap, thereby interfering with colonization. Future studies should examine the therapeutic potential of lactoferrin, perhaps as a supplement in infant formulas.
Cathelicidin-OA1, a novel antioxidant peptide identified from an amphibian, accelerates skin wound healing (2018)

Cathelicidins play pivotal roles in host defense. The discovery of novel cathelicidins is important research; however, despite the identification of many cathelicidins in vertebrates, few have been reported in amphibians. Here we identified a novel cathelicidin (named cathelicidin-OA1) from the skin of an amphibian species, Odorrana andersonii. Produced by posttranslational processing of a 198-residue prepropeptide, cathelicidin-OA1 presented an amino acid sequence of 'IGRDPTWSHLAASCLKCIFDDLPKTHN' and a molecular mass of 3038.5 Da. Functional analysis showed that, unlike other cathelicidins, cathelicidin-OA1 demonstrated no direct microbe-killing, acute toxicity and hemolytic activity, but did exhibit antioxidant activity. Importantly, cathelicidin-OA1 accelerated wound healing against human keratinocytes (HaCaT) and skin fibroblasts (HSF) in both time- and dose-dependent manners. Notably, cathelicidin-OA1 also showed wound-healing promotion in a mouse model with full-thickness skin wounds, accelerating re-epithelialization and granulation tissue formation by enhancing the recruitment of macrophages to the wound site, inducing HaCaT cell proliferation and HSF cell migration. This is the first cathelicidin identified from an amphibian that shows potent wound-healing activity. These results will help in the development of new types of wound-healing agents and in our understanding of the biological functions of cathelicidins.
Mapping Biological Current Densities With Ultrafast Acoustoelectric Imaging: Application to the Beating Rat Heart (2019)

Ultrafast acoustoelectric imaging (UAI) is a novel method for the mapping of biological current densities, which may improve the diagnosis and monitoring of cardiac activation diseases such as arrhythmias. This paper evaluates the feasibility of performing UAI in beating rat hearts. A previously described system based on a 256-channel ultrasound research platform fitted with a 5-MHz linear array was used for simultaneous UAI, ultrafast B-mode, and electrocardiogram (ECG) recordings. In this paper, rat hearts (n = 4) were retroperfused within a Langendorff isolated heart system. A pair of Ag/Cl electrodes were positioned on the epicardium to simultaneously record ECG and UAI signals for imaging frame rates of up to 1000 Hz and a mechanical index of 1.3. To account for the potential effect of motion on the UAI maps, acquisitions for n = 3 hearts were performed with and without suppression of the mechanical contraction using 2,3-butanedione monoxime. Current densities were detected for all four rats in the region of the atrio-ventricular node, with an average contrast-to-noise ratios of 12. The UAI signals' frequency matched the sinus rhythm, even without mechanical contraction, suggesting that the signals measured correspond to physiological electrical activation. UAI signals appeared at the apex and within the ventricular walls with a delay estimated at 29 ms. Finally, the signals from different electrode positions along the myocardium wall showed the possibility of mapping the electrical activation throughout the heart. These results show the potential of UAI for cardiac activation mapping in vivo and in real time.
Methodology for Complete Decorrelation of Power Supply EM Side-Channel Signal and Sensitive Data (2022)

Electro-magnetic (EM) side channel attacks have become a serious threat to security of Internet-of-Things (IoT) devices. Power supply generated by voltage regulators is one of the most common attack targets due to its strong EM emanations. In this brief we derive analytical conditions for complete theoretical decorrelation of the power supply EM side-channel signal and the sensitive data. The output of the power supply converter is modelled as amplitude modulation (AM) of the load signal by the converter capacitance that acts as a carrier. By applying Price theorem (Papoulis and Pillai, 2002), we obtain the exact theoretical conditions that converter capacitance needs to fulfil in order to prevent EM side-channel attacks. The conditions are further adapted for practical implementation. When the proposed methodology is applied to AES measured traces, the correlation coefficient between the leaked signal and the sensitive data is 0.05. Such low correlation indicates the proposed methodology is a promising candidate against the attacks that exploit AM signals to extract sensitive data, such as, TEMPEST and active EM attacks.

The lncRNA LOC102549805 (U1) modulates neurotoxicity of HIV-1 Tat protein (2020)

HIV-1 Tat is a potent neurotoxic protein that is released by HIV-1 infected cells in the brain and perturbs neuronal homeostasis, causing a broad range of neurological disorders in people living with HIV-1. Furthermore, the effects of Tat have been addressed in numerous studies to investigate the molecular events associated with neuronal cells survival and death. Here, we discovered that exposure of rat primary neurons to Tat resulted in the up-regulation of an uncharacterized long non-coding RNA (lncRNA), LOC102549805 (lncRNA-U1). Our observations showed that increased expression of lncRNA-U1 in neurons disrupts bioenergetic pathways by dysregulating homeostasis of Ca<sup>2+</sup>, mitigating mitochondrial oxygen reduction, and decreasing ATP production, all of which point mitochondrial impairment in neurons via the Tat-mediated lncRNA-U1 induction. These changes were associated with imbalances in autophagy and apoptosis pathways. Additionally, this study showed the ability of Tat to modulate expression of the neuropeptide B/W receptor 1 (NPBWR1) gene via up-regulation of lncRNA-U1. Collectively, our results identified Tat-mediated lncRNA-U1 upregulation resulting in disruption of neuronal homeostasis.
Evaluation of microencapsulation of a Bifidobacterium strain with starch as an approach to prolonging viability during storage (2001)

The production of small, uniformly coated microspheres containing viable bifidobacteria using an affordable and industrially convenient process, such as spray drying, has commercial implications for the production of probiotic products. Although popular for use as a coating polymer by the food industry, this study indicated that modified starches might not be suitable for use as an encapsulating material for probiotic strains.

Measured phase noise of the oscillator is -98 dBc at an offset frequency of 1 MHz.
Changes in blood lymphocyte populations in experimental bowel allograft rejection (1996)

Abstract The aim of this study is to measure percentages of lymphocyte populations and IL-2R cellular expression in peripheral blood during the rejection of a small bowel allograft (SBA) in the rat. Thirty rats were allotted to three groups: A, control, no transplantation (Tx); B, rats receiving an orthotopic SBA; C, similar SBA but with thymostimulin (TP-1) administered before Tx, aimed at increasing the intensity of and accelerating rejection. The percentages of CD19, CD5, CD4 and CD8 cells and of IL-2R were determined when rejection was present. Rejection appeared in rats in group B between days 11 and 26 post-Tx and in group C between days 6 and 7 post-Tx (P < 0.001). In both B and C groups, CD.5 and CD4 cells decreased (P < 0.005) and CD8 cells increased (P < 0.001). A correlation between CD8 and IL-2R content was found (P < 0.05). In group C, earliness of rejection correlated with the percentage of CD8 cells (P < 0.05) and the intensity of rejection with numbers of CD8 and CD19 cells (P< 0.05).
Relationship Between Staff Nurse Motivation Level and Patient Satisfaction In Selected Hospital and the Appreiviation are Staff Nurse Motivation and Patient Satisfaction (2023)

Background Nursing is a core job in the healthcare system; nursing staff constitutes the largest human resource element in healthcare organizations and therefore they seem to have a great impact on the quality of care, patient outcome, and satisfaction. The study aimed to investigate the relationship between staff nurse motivation and patient satisfaction. Design A descriptive correlational design was used to achieve the aim of the current study. Setting The study was conducted at Soad Kafafy Private University Hospital. Sample Two groups of samples were selected: the staff nurses sample consisted of (100 staff nurses) and the patient sample consisted of 100 patients. Tools Two tools were used in the study the first: the patient satisfaction questionnaire assesses patient satisfaction; it contains seven dimensions with a total of 51 items and the second: the staff nurses’ motivation questionnaire developed by the researchers to assess the nurses’ motivational factors. It contains seven dimensions with a total of 48 items. Result The results showed that there is a positive correlation between patient's satisfaction and nurse's motivation. Conclusion There was a significant relationship between staff nurses’ motivation and patient satisfaction. Recommendations The study recommended that hospitals should adopt motivation strategy for their nurses to motivate them, ensure nurses’ participation in decision-making processes that will enhance the clinical and organizational outcome, availability of motivation and incentive policies and procedures at every unit in the hospital, and further research should be done concentrating on adherences to motivational strategy.

Experimental Validation of Swarm Array Results using Mars Cube One (MarCO) A/B Downlink Signals (2020)

In this paper, we investigate the feasibility of calibrating an orbiting phased array composed of CubeSat class spacecraft together with a larger reference (or “chief”) spacecraft, comprising an overall Swarm Array. Considered as an analog to the Deep Space Network (DSN) Uplink Arraying problem [1], [2], a spaceborne Swarm Array can potentially deliver comparable or even greater operational performance than large monolithic spacecraft (such as increased datarates for telecommunications, or greater baselines for improved spatial resolution), thus increasing future mission capability but with significantly enhanced flexibility, evolvability and robustness.
Design of an OPAC database to permit different subject searching accesses in a multi-disciplines universities library catalogue database (1992)

This paper presents searching approaches and user interface capabilities of DUO, an Online Public Access Catalogue (OPAC) designed to permit the users of three Universities of the Northeast of Italy different subject searching accesses to the co-operative multi-disciplines library catalogue database.The co-operative catalogue database is managed by one of the software systems developed under the italian national project for library automation: the SBN project. Since the SBN database has not been designed to be efficiently accessed for end-user searches, the DUO database has been designed to avoid duplication of the SBN database data and to be usable for making efficient subjects accesses to the catalogue documents. The DUO design choices are presented, in particular the main choice of designing a “virtual” document that corresponds to each SBN document and that has unstructured data usable for subject search purposes.The paper presents a new kind of user-OPAC dialogue that makes available to the user different search approaches and on-line dictionaries. In particular the user during the interaction with the search tool can represent his information needs with the support of interface capabilities that are based on retrieval path history, and words and codes on-line dictionaries.DUO is the first Italian OPAC that has been made openly available to users of universities and research institutions. For this reason, it is also the first time that OPAC log data is going to be collected in Italy. This work mainly intends to make a modern OPAC available to the users of a SBN catalogue database, but it is going to permit also to build up a knowledge on OPAC usage in Italy.
Fabry–Perot based strain insensitive photonic crystal fiber modal interferometer for inline sensing of refractive index and temperature (2015)

We report a highly stable, compact, strain insensitive inline microcavity-based solid-core photonic crystal fiber (SCPCF) modal interferometer for the determination of the refractive index (RI) of an analyte and its temperature. The interferometer is fabricated by splicing one end of SCPCF with single-mode fiber (SMF) and the other end with hollow-core PCF. This is followed by cleaving the part of the solid glass portion possibly present after the microcavity. The formation of the cavities at the end faces of the SCPCF results in reduction of the period of the interference pattern that helps in achieving distinctiveness in the measurement. Three sensor heads have been fabricated, and each has a different length of the collapsed region formed by splicing SMF with SCPCF. The response of the sensors is found to be sensitive to the length of this collapsed region between SMF and SCPCF with a sensitivity of 53 nm/RI unit (RIU) and resolution of 1.8×10(-4) RIU. The temperature response of the sensor is found to be linear, having a temperature sensitivity of 12 pm/°C. In addition to these findings, the effect of strain on the proposed structure is analyzed in both wavelength and intensity interrogation.

Rho kinase mediates serum-induced contraction in fibroblast fibers independent of myosin LC20 phosphorylation (2003)

Fibroblasts form fibers when grown in culture medium containing native type 1 collagen. The contractile forces generated can be precisely quantified and used to analyze the signal transduction pathways regulating fibroblast contraction. Calf serum (30%) induces a sustained contraction that is accompanied by a transient increase in intracellular calcium ([Ca(2+)](i)). W-7, a calmodulin inhibitor, KN-62, an inhibitor of calcium/calmodulin-dependent protein kinase, and ML-7, a myosin light-chain kinase inhibitor, had no effects on either the contraction or the [Ca(2+)](i) responses. Neither genistein, a tyrosine kinase inhibitor, nor calphostin C, a protein kinase C inhibitor, had major effects on force or [Ca(2+)](i). In contrast, the Rho kinase inhibitors (R)-(+)-trans-N-(4-pyridyl)-4-(1-aminoethyl)-cyclohexanecarboxamide (Y-27632) and HA1077 depressed the contraction in a dose-dependent manner without affecting the [Ca(2+)](i) response. Stress fiber formation was also suppressed by Y-27632. Surprisingly, calf serum, Y-27632, and calf serum plus Y-27632 did not alter mono- or diphosphorylation of the myosin regulatory light chain (MRLC) compared with control untreated fibers. These results suggest that the sustained contraction of NIH 3T3 fibroblast fibers induced by calf serum is mediated by Rho kinase but is independent of a sustained increase in [Ca(2+)](i), calcium/calmodulin- or protein kinase C-dependent pathways, or increases in MRLC phosphorylation.
Seasonal endocrine changes in Baltic salmon, Salmo salar, immature parr and mature male parr. I. Plasma levels of five androgens, 17α-hydroxy-20β-dihydroprogesterone, and 17β-estradiol (1990)

Plasma levels of the androgens testosterone (T) and 11-ketotestosterone (OT), the progestin 17α-hydroxy-20β-dihydroprogesterone (17,20-P), and the estrogen 17β-estradiol (E 2 ) were measured by radioimmunoassay in monthly samples from immature parr (mostly females) and mature male parr of Baltic salmon, Salmo salar. The parr belonged to the Umeälven stock, northern Sweden, and were kept at ambient photoperiod and temperature throughout their rearing period. The sampling began in February at the end of their 2nd year and continued until December. 11β-Hydroxytestosterone (OHT), 11β-hydroxyandrostenedione (OHA), and 11-ketoandrostenedione (OA) were measured at selected times only. The levels of OT, T, and 17,20-P were low in mature and immature fish from February until the summer; in the immature fish they remained low for the entire period. There were only minor differences in steroid levels between mature and immature fish before and during the first half of smoltification (May). This was also the case for OHT, OHA, and OA. In the mature fish, the levels of T and OT started to rise in June. T peaked in August–October, and OT in September–October. Both androgens dropped to a very low level in December. OT displayed the highest levels of all androgens in the reproductive season. 17,20-P rose to a high level in October, peaked in November, and was still high in December. E 2 levels were relatively high in winter, declined during spring in both groups, and rose again in autumn. The poorer adaptability to seawater that has been observed in mature vs. immature fish could not be explained by differences in steroid levels at the time of smoltification.
The Effect of Soluble Lubricant on Surface Imprinting in Temper Rolling by 4 Hi Rolling Mill (2009)

The surface roughness of carbon steel sheets is controlled by dull roll surface imprinting by temper rolling. In most cases, temper rolling is performed using a lubricant or under a dry condition. However, the oil film of the lubricant and its lubricating ability have not been clarified. In this study, the effect of a lubricant on surface imprinting by temper rolling was investigated under the following three lubrication states: a dry condition (no lubricant), with a water-soluble lubricant and with a mineral oil. Temper rolling experiments for as-annealed low-carbon steel strips and as-annealed high-carbon steel strips were conducted in the reduction range of 1 to 3%, using the 4-high rolling mill. A shot-dull roll and an electric-discharged dull roll were employed as work rolls. The surface texture of temper rolled strips was observed directly, and surface textures in terms of the mean roughness (Ra), three-dimensional texture, cross-sectional profile, material ratio curve and probability density in order to compare the effect of the lubrication states. As a result, for high-carbon steel, the use of the water-soluble lubricant leads to better surface imprinting than the dry condition and the use of the mineral oil. The use of the mineral oil results in the least surface imprinting. For the low-carbon steel, the use of the water-soluble lubricant and the dry condition lead to better surface imprinting than the use of the mineral oil.
Electrical model of a thin dielectric film with a bottom electrode of non-negligible distributed resistance (2016)

Thin films are appealing objects of scientific studies due to attractive functionalities and novel physical phenomena. However, choice of the lower electrode (which is between the film and the substrate) is often limited for various reasons, and it might not be suitable for radiofrequency investigations of the film due to comparable impedances of the film and the contact. This paper presents a new theoretical model for complex heterostucture, which could describe impedance fairly well and would allow extracting dielectric permittivity of the functional ferroelectric layer even in the case of distributed resistance of the bottom electrode. The effectiveness of the presented theoretical model was proved by approximation of experimental data. The model has several disadvantages, such as complexity, suitability for linear systems only, potential failure in presence of electric DC bias. Despite the drawbacks, the model describes the experimental data in a physically proper way, unlike equivalent circuit model. Furthermore, an algorithm to find static resistivity and dielectric permittivity of the film in a simple way is also proposed.
