Effect of tilt angle on the performance of a thin-film photovoltaic system (2022)

Solar energy is among the cleanest and most sustainable ways to enhance electrical supply's resiliency and reliability for domestic and industrial use. A Photovoltaic (PV) system is the most effective way of capturing solar energy. Long-term warranty, low-cost maintenance, and vast resource availability, solar power generation has an advantage over other approaches. Thin-film technology PV cells are a new kind of solar cell that offers an efficient technique of generating electricity from sunlight. The thin-film PV technology (FFMAT-10, Renovagen, UK) used in this study can supply 0.9 to 1.6 kW of energy to the fast-fold energy hub. The hub’s system status and configuration display battery power input, battery’s state of charge, thin-film PV power and AC power output. Two fast-fold mats (with a surface area of 25.3 m2) were connected to the energy hub. Increasing energy demand coupled with frequent power outages, and inaccessibility of electricity in rural areas necessitates the usage of PV systems at their best performance level. The study objective, therefore, sought to assess the effect of tilt angle on the performance of the thin-film PV system. The study was conducted at Kimicha in Kirinyaga County Kenya, and Juja, Kenya at tilt angles between 0o to 30o. The results indicated that the mean peak PV power for Kimicha was 347.8±231.9 W at 5o and 517.7± 131.3 W at 15ofor Juja. The maximum solar radiation during the study period was 1086.4 ±211.4 W/m2 for Juja and 973.5±219.93 W/m2 for Kimicha. From the study, it was realized that an optimal tilt angle yields optimum solar radiation that translates to maximum power production. Even though the study was conducted in two different regions, it may be applied to any other geographical location. The outcome of the study aids in acquiring self-sustaining power in the most remote locations where electricity is scarce as well as improving energy security.
Augmenting MulVAL with automated extraction of vulnerabilities descriptions (2017)

Network attack graphs are a type of analysis tool that can be used to determine the impact that security vulnerabilities have on the network. It is important, then, for attack graphs to be able to represent enough information to aid this analysis. Moreover, they must be able to handle and integrate new vulnerabilities that are being discovered by the security community. We developed a prototype tool that can parse vulnerability descriptions, as provided in the CVE, to retrieve relevant information for generating interaction rules that can be incorporated into an attack graph generation software. The tool is able to parse correctly about 88.15% of sampled CVEs. Such a tool allows for the attack graphs generated to be up-to-date with any recently discovered vulnerabilities. Furthermore, the additional information provided by the generated rules enable more information to be used and represented in attack graphs in a simpler fashion, facilitating smoother analyses.
Peri‐implant health around screw‐shaped c.p. titanium machined implants in partially edentulous patients with or without ongoing periodontitis (2001)

The relationship between periodontitis and peri-implantitis remains a matter of debate. The present study compared, "within" randomly chosen partially edentulous patients (n=84 subjects, 97 jaws), the marginal bone loss around teeth and implants during 5 years (range 3 to 11 years) following the first year of bone remodelling. The patients had all been rehabilitated by means of screw-shape c.p. titanium implants with a machined surface (Brånemark system). During the 5 years observation interval, periodontal parameters (marginal bone and attachment loss, the latter for teeth only) were collected together with data on confounding factors (smoking, oral hygiene, tooth loss). Marginal bone loss was measured through long-cone intra-oral radiographs. The mean "interval" bone loss was significantly (P=0.0001) higher around teeth (0.48+/-0.95 mm) than around implants (0.09+/-0.28 mm). The corresponding data for the "worst" performing tooth (0.99+/-1.25 mm) and implant (0.19+/-0.32 mm) per subject showed the same tendency. Neither attachment nor bone loss around teeth correlated with marginal bone loss around implants. This study indicated that the rate of bone loss around screw-shape c.p. titanium implants with a machined surface (Brånemark system implants) was not influenced by the progression rate of periodontal destruction around the remaining teeth within the same jaw.

Telecom power planning for natural and man-made disasters (2007)

This paper discusses a planning framework to reduce telecommunication network power supply vulnerability during natural and man-made disasters. The analysis proposes a three-part structure for a plan. The first part is an assessment of risk. Risk assessment involves identifying potential disasters at each site as well as evaluating the probability of occurrence and its impact. Impact evaluation focuses on electric grid, roads, and natural gas distribution infrastructure. The second part is an evaluation of resources and logistics. Use of alternative technologies to diversify energy supply, such as distributed generation power units, is discussed. The last part of the plan is its execution. The importance of record keeping and control of the plan outcome during this phase is emphasized, as well as conducting periodic drills to test and improve the plan.
Effects of Acidic Fog Containing H2O2 on the Sensitivity of Agricultural Crops to Important Fungal Diseases (1987)

During the recent years acidic fog and its effects on agricultural plants and forest trees have been more and more the subject of investigations, especially because fog is much more acidic than acid rain. Analyses of fog and cloud water have shown that it may contain a considerable amount of H2O2 with a concentration of 100 to 5000 ppb (1,2). H2O2 is an oxidant well soluble in water. After it has been proved that H2O2 plays an important role in forest decline, we now want to present first results about its influence on certain agricultural plants especially under the aspect of host-parasite interactions.

High-Q RF MEMS capacitor with digital/analog tuning capabilities (2008)

This paper presents an RF MEMS switchedcapacitor suitable for tunable filters and reconfigurable matching networks. The switched-capacitor contains design features that result in a tunable capacitance ratio of 5–7, a high-Q (≫ 100) at C to X-band frequencies, and excellent reliability performance. The switched-capacitor has been temperature cycled to 120° C with only a 3–4 V change in the pull-down voltage. The design also features a digital switched-capacitor mode and an analog tuning mode, making it ideal for precision tuning.
Generation and validation of a highly sensitive bioluminescent HIV-1 reporter vector that simplifies measurement of virus release (2020)

Abstract Background The continued persistence of HIV-1 as a public health concern due to the lack of a cure calls for the development of new tools for studying replication of the virus. Here, we used NanoLuc, a small and extremely bright luciferase protein, to develop an HIV-1 bioluminescent reporter virus that simplifies functional measurement of virus particle production. Results The reporter virus encodes a Gag protein containing NanoLuc inserted between the matrix (MA) and capsid (CA) domains of Gag, thereby generating virus particles that package high levels of the NanoLuc reporter. We observe that inserting the NanoLuc protein within HIV-1 Gag has minimal impact on Gag expression and virus particle release. We show that the reporter virus recapitulates inhibition of HIV-1 particle release by Gag mutations, the restriction factor tetherin, and the small-molecule inhibitor amphotericin-B methyl ester. Conclusion These results demonstrate that this vector will provide a simple and rapid tool for functional studies of virus particle assembly and release and high-throughput screening for cellular factors and small-molecules that promote or inhibit HIV-1 particle production.

These findings suggest a possible role of chronic hepatitis B infection in the pathogenesis of carotid arteriosclerosis.
Linear LLR approximation for iterative decoding on wireless channels (2009)

On a fading channel with no channel state information at the receiver, true log-likelihood ratios (LLR) are complicated functions of the channel output. It is assumed in the literature that the power of the additive noise is known and the expected value of the fading gain is used in a linear function of the channel output to find approximate LLRs. This approach, however, is not optimal in the sense of bit error rate performance. In this paper, we introduce a measure of accuracy for the approximate LLRs based on their probability density function and we show that this measure provides a very convenient tool for finding good approximate LLRs. Assuming that the power of the additive noise is known, and using the proposed measure, we find a linear LLR approximation whose performance is extremely close to that of the true LLR calculation on an uncorrelated Rayleigh fading channel. These results are then extended to the case that the noise power is also unknown and a performance almost identical to the previous case is obtained.
50 Gb/s Transmission over Uncompensated Link up to 20 km Exploiting DSP-Free Direct-Detection (2018)

We experimentally transmit 50Gb/s over 20km uncompensated SMF with a conventional DSP-free OOK direct detection receiver, exploiting combined amplitude phase shift codes. A simplified implementation based on analog electronics is also validated at 50Gb/s.
Recent developments in high power 2.3-2.4 μm diode lasers (2007)

Mid-infrared light emitters capable of room temperature continuous-wave (CW) operation are in demand for variety of applications ranging from medical diagnostics to missile countermeasures. Room temperature type-I quantum-well (QW) GaSb-based lasers, laser arrays and light emitting diodes operating in the spectral range from below 2 to over 3&mgr;m have been reported. The maximum CW output power from 1cm-wide 2.35&mgr;m linear laser array was 10 W, in quasi-CW operation (30 &mgr;s pulse, 300 Hz pulse repetition frequency) the maximum measured power is 18.5 W. In short pulse operation heating is negligible, and the light-current characteristics remains linear to beyond 20 W at 100 A.
Evaluating ELISA, Immunofluorescence, and Lateral Flow Assay for SARS-CoV-2 Serologic Assays (2020)

Comparison of five systems for SARS-CoV-2 IgG and IgM antibodies showed limited sensitivity and overall concordance. The place and indications of serological status assessment with currently available tools in the CoVID-19 pandemic need further evaluations.
[A Case of Laparoscopic Low Anterior Dissection for Rectal Carcinoma with Left-Sided Inferior Vena Cava]. (2017)

A 43-year old-male was admitted to the hospital for the treatment of rectal carcinoma. Preoperative abdominal computed tomography(CT)revealed a left inferior vena cava. There is no report of the patient with left inferior vena cava which focused on an anatomical feature of autonomic nerves. We report a case of rectal cancer patient with left inferior vena cava who underwent autonomic nerve-sparing laparoscopic low anterior resection, and review the relevant literature here.
Unexpected Viability of Pyridyl Methanimine-Based Ligands for Transition-Metal-Mediated Living Radical Polymerization in Aqueous Media at Ambient Temperature (2000)

Pyridyl methanimine-based ligands are used in aqueous media at neutral pH for the efficient living radical polymerization of hydrophilic monomers. High conversions (>90%), good molecular weight control, and low polydispersities (Mw/Mn < 1.20) were obtained for the polymerization of monomethoxy-capped oligo(ethylene glycol) methacrylate at 20 °C; faster rates, reduced control, and higher polydispersities were obtained at elevated temperatures.
P53 mutations in human adrenocortical neoplasms (1994)

The mechanisms of tumorigenesis of adrenocortical neoplasms have not been elucidated as yet. However, loss of heterozygosity at chromosomal locus 17p has been consistently observed in adrenocortical cancer. p53 is a recessive tumor suppressor gene located on chromosome 17p. Mutations in the p53 gene play an important role in the tumorigenesis of diverse types of human neoplasms including breast and colon cancers. More than 90% of all mutations discovered in such tumors have been detected in 4 hot spot areas that lie between exons 5 and 8. In contrast to wild-type p53, mutant p53 accumulates intracellularly and can be easily detected by immunohistochemistry. We therefore investigated the frequency of p53 mutations in human adrenocortical neoplasms using molecular biology and immunohistochemistry techniques. Five patients with adrenocortical adenomas (5 female; ages 39-72 yr), 11 patients with adrenocortical carcinomas (8 female, 3 male; ages 15- 50 yr), and two adrenocortical tumor cell lines were studied. After DNA extraction from frozen tumor tissue or paraffin-embedded material, exons 5 through 8 were amplified using the polymerase chain reaction and directly sequenced by the dideoxy termination method. Immunohistochemistry was performed on paraffin-embedded tumor specimens obtained during adrenalectomy using a monoclonal antibody reacting with both wild-type and mutant p53. Prevalence of mutations was adenomas, 0/5, carcinomas, 3/11, and adrenocortical cell lines, 2/2. Single point mutations were detected in 3 cases (exons 5, 6, and 7, respectively), and rearrangements of exon 7/8 and 8 were found in 2 cases. Immunohistochemistry detected strong nuclear and/or cytoplasmic p53 immunoreactivity in all adrenocortical carcinomas with point mutations of the p53 gene but not in adenomas and carcinomas with the wild-type sequence or with deletion/rearrangement of the p53 gene. We conclude that p53 plays a role in the tumorigenesis of adrenocortical carcinomas but is of less importance to benign adenomas.

Risk Factors for Serious Adverse Effects of Thiopurines in Patients with Crohn&amp;#8217;s Disease (2013)

Active smoking and GSTM1-null genotype appear to be risk factors for thiopurine induced SAEs (i.e. myelosuppression, hepatotoxicity and pancreatitis) in patients with CD. Corroboration of these associations in larger cohorts is warranted.
Biotemplated synthesis of highly divided MoS2 catalysts (2012)

Cellulose fibres can be topotactically transformed to highly divided molybdenum sulfide by means of reflux in ethylene glycol in the presence of ammonium heptamolybdate and elemental sulfur. The product partially replicates the morphology features of the initial organic fibres and possesses high specific surface area and developed mesoporosity. As established by characterizations including EXAFS and TEM, during the solvothermal reaction, molybdenum sulfide with composition close to MoS3 is formed simultaneously with the reductive degradation of cellulose. Further heating in hydrogen yields carbon-stabilised MoS2 dispersions. Promotion with cobalt leads to a highly active unsupported hydrodesulfurization catalyst.
356428 ANALYSIS OF BRAKING BEHAVIOR FOR TRAIN DRIVER'S TO DETECT UNUSUAL DRIVING(Human Factor,Technical Session) (2009)

Methods for detecting any unusual conditions affecting a driver, based on driving behavior, are proposed in this paper. This study analyses driving behavior of train drivers using a train driving simulator that simulates train operation. We focus on braking behavior when approaching a station. The method of detecting unusual braking operation is examined by giving drivers mental calculation problems as a mental workload. The variance of the brake-handle operation was significantly larger when a mental workload was imposed, indicating the possibility of determining the driving characteristics of individuals. We examined the possibility of detecting unusual driving by evaluating the deceleration trajectory.
Hydrodenitrogenation of quinoline and coal using transition metal sulfides (1988)

This study investigates the effectiveness of unsupported, precipitated transition metal sulfides as HYD and HDN catalysts in both a quinoline system and a coal liquefaction system. The transition metal sulfides of moderate surface areas were produced by a method developed by Chianelli and Dines in the late 1970's. These materials crystallize in weakly interacting layers which allow for ready intercalation of appropriate species. A number of different transition metal sulfides have been tested for HDS activity using dibenzothiophene and are good candidates for hydrodenitrogenation (HDN) studies. The degree of HYD and HDN of quinoline and the reaction products from coal liquefaction were determined using precipitated transition metal sulfides and compared to commercial transition metal sulfides, commercial hydrotreating catalysts such as CoMo/Al/sub 2/O/sub 3/ and NiMo/Al/sub 2/O/sub 3/, and platinum containing catalysts such as Pt/SiO/sub 2/ and PtS/sub 2/.
An Integral Face Formulation for Thin Non-Conductive Magnetic Regions (2019)

This paper deals with the use of the volume integral method to compute the magnetic anomaly created by a non-conductive ferromagnetic thin shell placed in a static inductor field. An original facet integral formulation considering the magnetic induction as unknowns is presented. The use of thin shell element assumption leads to a surface mesh decreasing highly the number of elements so the computation cost. The method is very performing in terms of speed and accuracy.
Alignment Between Heart Rate Variability From Fitness Trackers and Perceived Stress: Perspectives From a Large-Scale In Situ Longitudinal Study of Information Workers (2022)

A significant but small relationship between perceived stress and HRV was found. Thus, although HRV is associated with perceived stress in laboratory settings, the strength of that association diminishes in real-life settings. HRV might be more reflective of perceived stress in the presence of specific and isolated stressors and research-grade sensing. Relying on wearable-derived HRV alone might not be sufficient to detect stress in naturalistic settings and should not be considered a proxy for perceived stress but rather a component of a complex phenomenon.
Single exposures to antiproliferatives: long-term effects on ocular fibroblast wound-healing behavior. (1997)

Fibroblasts whose growth was arrested using single, short exposures to 5FU or MMC appear to be capable of performing several crucial aspects of wound healing, including the expression of growth factors and receptors and ECM molecules and the ability to migrate. These findings may help explain why in some patients treated with antiproliferatives, glaucoma filtration surgery fails because of scarring.
In vitro evaluation of cerebrospinal fluid velocity measurement in type I Chiari malformation: repeatability, reproducibility, and agreement using 2D phase contrast and 4D flow MRI (2021)

Agreement, repeatability, and reproducibility of 2D PC MRI and 4D Flow detection of peak CSF velocities was quantified using a patient-specific in vitro model of Chiari malformation. In combination, the greatest factor leading to measurement inconsistency was determined to be a lack of reproducibility between different MRI centers. Overall, these findings may help lead to better understanding for application of 2D PC MRI and 4D Flow techniques as diagnostic tools for CSF dynamics quantification in Chiari malformation and related diseases.

Multi-visit TAMs to Reduce the Post-Bond Test Length of 2.5D-SICs with a Passive Silicon Interposer Base (2011)

2.5D Stacked ICs (2.5D-SICs) consist of multiple active dies (or 3D towers of active dies), which are placed side-by-side on top of and interconnected through a passive silicon interposer base which contains Through-Silicon Vias (TSVs). A previously presented post-bond test and Design-for-Test(DfT) strategy for such 2.5D-SICs implements a serial Test Access Mechanism (TAM) for interposer and micro-bump testing. In addition, it tries to identify an as-wide-as-possible set of functional interposer interconnects that can be reused as parallel TAMs to the various dies. In this paper, we extend that approach with the concept of Multi-Visit TAMs, i.e., parallel TAMs which are allowed to visit the same die more than once. For minimal additional hardware costs, the Multi-Visit TAMs succeed significantly more often in identifying a valid parallel TAM and achieve significantly lower test lengths.
