Analysis of the Expression and Clinical Significance of VIPR1 in Lung Adenocarcinoma Based on TCGA Database

Background: The expression of VIPR1 is associated with the prognosis of many malignant tumors. To analyze the expression and clinical significance of vasoactive intestinal peptide Types I (VIPR1) in lung adenocarcinoma based on The Cancer Genome Atlas (TCGA)database. Methods and results：The RNASeq data, clinical data and prognosis data of lung adenocarcinoma and normal lung tissue were downloaded from TCGA database. The expression difference of VIPR1 mRNA in lung adenocarcinoma and normal lung tissue（p<0.05）, and the correlations of the expression levels of VIPR1 in lung adenocarcinoma with clinical pathological characteristics and prognosis were analyzed. The possible regulatory signaling pathways of VIPR1 were predicted by the gene set enrichment analysis (GSEA). CIBERSORT was used to analyze the expression of immune cells in tumor tissues and normal tissues. TIMER was used to analyze the relationship between VIPR1 and immune cell expression. The expression levels of VIPR1 mRNA in lung adenocarcinoma tissues were significantly lower than that in normal lung tissues. The expression levels of VIPR1 mRNA were significantly correlated with gender, T staging，N staging and pathological grade（p<0.05）but not with age, M staging and survival status. Survival analysis showed that the survival time of patients with low expression of VIPR1 was significantly lower than that of patients with high expression. In addition, the expression level of VIPR1 in lung adenocarcinoma was negatively correlated with the infiltration level of myeloid inhibitory cells (r = -0.448, p < 0.01). Through GSEA functional enrichment analysis, it was found that VIPR1 was mainly related to cell cycle pathway, p53 signal pathway, DNA replication pathway, RNA degradation pathway and so on.Conclusions：VIPR1 gene may be a new target for the clinical prognosis and targeted therapy of lung adenocarcinoma.
Simulation of MEMS Cantilever Biosensor and Analysis of Readout Methods for Tuberculosis Detection

This paper deals with designing a MEMS cantilever which can function as biosensor for tuberculosis detection. In this study we investigate the MEMS based biosensor to detect Tuberculosis based on capacitive sensing, peizoresistive and resonant frequency methods. We also examine which method has enhanced performance. Early detection and treatment of diseases can facilitated only if we are able to detect pathogenic and physiologically relevant molecules in the body with high sensitivity and specificity.Early detection of diseases reduce the risk of patients being pushed to advanced stages of many diseases.This sensor is used for early detection of Tuberculosis using the antigen antibody reaction.Tuberculosis can be detected by monitoring the presence of disease causing antigen in the blood stream.The presence of disease causing antigen in the blood can be monitered by using this microcantilever based diagnostic device. The sensing principle varies according to the device, the nature of the analyte molecules, and the precision required. Capacitance, piezoresistance and resonance frequency are among the read out methods depending upon the mechanical properties of the device. The biosensor structure is designed and simulated using Coventorware, Intellisuit and HFSS software. This microcantilever based biosensor can detect tuberculosis by immobilizing specific antibodies on the microcantilever.These antibodies are specific to TB antigen 85 complex.When the patient sample containing TB antigen 85 complex is placed on the cantilever biomolecular interactions take place between TB antigens and the antibodies immobilized on the upper surface of the microcantilever.This causes microcantilever to bend and facilitates to detect the presence of Tuberculosis.Bending of the cantilever can be measured by capacitive sensing, peizoresistive and resonant frequency shift methods.
The Application of Lean Methods in Corporate Sustainability—A Systematic Literature Review

This paper reviews the application of lean methods for corporate sustainability and highlights demands for future research. With the help of a systematic literature review, papers at the interface of lean and sustainability were identified and matched to a standardized list of lean methods to assess their frequency in the context of sustainability. In a further step, papers containing actual case studies were analyzed in more detail regarding specific application settings, sustainability dimensions, measurability of sustainability impact, and other criteria. The quantitative analysis of 363 publications shows frequent use of lean methods such as just in time and value stream mapping in the context of sustainability, and a surprisingly low use of other approaches such as karakuri, milk run, or chaku chaku. The in-depth analysis of 81 case studies reveals the primacy of intra-company and ecological assessments in the lean context, while social and inter-company aspects remain rather underexposed. This study complements existing research on lean and sustainability by systematically analyzing specific lean methods in the context of sustainability and by further exploring the sustainability characteristics of such lean applications.
THE COLOUR BLIND DRIVER

An analysis is made of the handicap suffered by drivers with defective colour vision, and laboratory and field investigations concerning their ability to safely recognise signal lights is reviewed. On the basis of a cost-effectiveness analysis it is argued that the imposition of a colour vision standard on drivers could well yield returns comparable to those from traffic engineering measures such as improvement of street lighting. Since a colour vision standard would be hardship to a significant number of people who wish to drive the alternative of improving signal and warning lights is preferred although it will be some time before sufficient improvement can be made to make the road system safe for colour vision defectives. In the meantime there should be a colour vision standard, if not for all drivers, certainly for drivers of commercial vehicles. Language: en
Interrelated Effects of Pitch Rate and Pivot Point on Airfoil Dynamic Stall

Abstract : Experimental investigations were conducted to study energetic dynamic stall vortices and the associated unsteady aerodynamics generated by a pitching NACA 0015 airfoil. The airfoil model was pitched from zero degrees to 60 degrees at constant pitch rates of 460 deg/sec, 920 deg/sec, and 1380 deg/sec about its quarter-chord, half-chord, and three quarter-chord positions. Extensive 35mm still photographs and 16mm high-speed movies, both employing smoke wire flow visualization, visually documented the initiation and development of the time dependent dynamic stall phenomena. Hot-wire anemometry measurements were also made which provided for more quantitative analysis of the unsteady separated flowfields. Pitch rate and pivot point were shown to have interrelated effects on the development of the dynamic stall flowfield. In many cases similar 'looking' flowfields were generated by different combinations of pitch rate and pivot point. However, significant differences were observed in the near-surface velocity profiles. (edc)
Bio-inspired tactile sensing arrays

This work presents the development of tactile sensing arrays, inspired by cutaneous sensing in humans, for the fingertips of a humanoid robot. The tactile sensing arrays have been developed in two phases. Microelectrode arrays (MEA), having 32 sensing elements - each epoxy adhered with 25μm thick piezoelectric polymer (PVDF-TrFE) film, were fabricated in the first phase. When connected to the gate of FET devices (external to the chip), each element on MEA acts like an extended gate; thereby facilitating modulation of charge in the induced channel by the charge generated in PVDF-TrFE film - as a result of applied force. Thus, each sensing element converts force into voltage. The tactile sensing arrays developed in second phase work on the same principle but are free from any extended gate. These arrays (having 25 sensing elements) use POSFET (Piezoelectric Oxide Semiconductor Field Effect Transistors) touch sensing elements - in which, piezoelectric polymer film is directly spin coated on the gate area of the FET devices. Thus, a POSFET touch sensing element 'senses and partially processes at same site' - as is done by receptors in human skin. The spatial-temporal performance of these chips is similar to that of skin in the human fingertips.
LAMA2 Nonsense Variant in an Italian Greyhound with Congenital Muscular Dystrophy

A 4-month-old, male Italian Greyhound with clinical signs of a neuromuscular disease was investigated. The affected dog presented with an abnormal short-strided gait, generalized muscle atrophy, and poor growth since 2-months of age. Serum biochemistry revealed a marked elevation in creatine kinase activity. Electrodiagnostic testing supported a myopathy. Histopathology of muscle biopsies confirmed a dystrophic phenotype with excessive variability in myofiber size, degenerating fibers, and endomysial fibrosis. A heritable form of congenital muscular dystrophy (CMD) was suspected, and a genetic analysis initiated. We sequenced the genome of the affected dog and compared the data to that of 795 control genomes. This search revealed a private homozygous nonsense variant in LAMA2, XM_022419950. 1:c.3285G>A, predicted to truncate 65% of the open reading frame of the wild type laminin α2 protein, XP_022275658. 1:p.(Trp1095*). Immunofluorescent staining performed on muscle cryosections from the affected dog confirmed the complete absence of laminin α2 in skeletal muscle. LAMA2 loss of function variants were shown to cause severe laminin α2-related CMD in humans, mouse models, and in one previously described dog. Our data together with current knowledge on other species suggest the LAMA2 nonsense variant as cause for the CMD phenotype in the investigated dog.
Shielded Electronic Current Transformer

A current transformer with nominal ratio 10 A to 10 mA, intended for low frequencies applications, was developed. It includes an electronic device to reduce the magnetizing current, and a continuos shield in the secondary winding in order to eliminate the effect of stray capacitances. These lead to high accuracy results (ratio errors and phase-displacements in the order of 10-6). It is proposed to leave the cable-shield potential floating
Propulsive performance from oscillating propulsors with spanwise flexibility

The propulsive performance of oscillating foils with spanwise flexibility was studied using a time-domain panel method. The work was done to assess the effects of spanwise flexibility on the propulsive efficiency of these propulsors, especially those employed by relatively fast swimming marine animals. The method is valid for three-dimensional attached flows around the actual planforms found on these animals and was used in the study reported here to assess the performance of the flukes of an immature fin whale (Balaenoptera physalus). It is shown that passive spanwise flexibility reduces propulsive efficiency, but that propulsive efficiency of these planforms can be increased, over the value for an equivalent rigid foil, by careful control of the phase of the spanwise flexibility relative to other motion parameters.
Classical T Tauri stars: accretion, wind, dust

Classical T Tauri stars (CTTS) are at the early evolutionary stage when the processes of planet formation take place in the surrounding accretion disks. Most of the observed activity in CTTS is due to magnetospheric accretion and wind flows. Observations of the accreting gas flows and appearance of the line-dependent veiling of the photospheric spectrum in CTTS are considered. Evidence for the dusty wind causing the observed irregular variability of CTTS is presented. Photometric and spectroscopic monitoring of two CTTS, RY Tau and SU Aur, has been carried out atthe Crimean Astrophysical Observatory since 2013 aimed at studying the dynamics of accretion and wind flows on time scales from days to years. The observed variations in the dynamical parameters may be caused by changes in the accretion rate and in the global magnetic fields of CTTS.
Überwachung und Modellierung der geologischen CO2‐Speicherung – Erfahrungen vom Pilotstandort Ketzin, Brandenburg (Deutschland)

Der Pilotstandort Ketzin in Brandenburg ist das erste und bisher einzige aktive CO2‐Speicherprojekt in Deutschland. Seit Beginn der Einspeicherung von Kohlenstoffdioxid (CO2) im Juni 2008 wurden bis Dezember 2011 mehr als 56.000 t CO2 erfolgreich in Sandsteinhorizonte in einer Tiefe von 630 bis 650 m injiziert. Die Injektion von CO2 wird von einem der weltweit umfangreichsten wissenschaftlichen Forschungs‐ und Entwicklungsprogramme begleitet. Die Ergebnisse zeigen, dass (i) die geologische Speicherung von CO2 am Pilotstandort Ketzin sicher, verlässlich und ohne Gefährdung von Mensch und Umwelt verläuft, (ii) eine sinnvoll eingesetzte Kombination verschiedener geochemischer und geophysikalischer Überwachungsmethoden in der Lage ist, bereits geringe Mengen CO2 zu detektieren und ihre räumliche Ausdehnung abzubilden, (iii) die durch das injizierte CO2 induzierten Wechselwirkungen zwischen Fluid und Gestein am Standort Ketzin keine signifikanten Auswirkungen haben und die Integrität der Speicher‐ und Deckgesteine nicht beeinflussen, und (iv) numerische Simulationen das zeitliche und räumliche Verhalten des injizierten CO2 wiedergeben können.
Guidance law switching logic considering the seeker's field-of-view limits

Abstract The impact time control guidance (ITCG) method, which has been proposed recently, can be applied successfully to a salvo attack of multiple missiles. Compared to the proportional navigation guidance law, this guidance method makes additional manoeuvres to synchronize the impact times. However, such manoeuvres do not consider the manoeuvrability and the seeker's field-of-view (FOV) of a missile and may cause the target to move out of the missile seeker's FOV; maintaining the seeker lock-on condition during the engagement is critical for missile guidance. To solve this problem, two methods are presented in this article: one is based on the calculation of minimum and maximum flight times considering the missile's manoeuvring limit and the seeker's FOV limit to check the available impact time. The other is based on guidance law switching logic that keeps the target look angle of the seeker constant. These methods can provide the boundary limit of the impact time of the salvo attack and prevent the lock-on failure because of the seeker's FOV limit of the missile during the homing phase when the ITCG is used. This method was applied to the case of a time critical salvo-attack of multiple missiles, which have manoeuvring limit and the seeker's FOV limit, and desired results were obtained.
SOA based C4I common-view interoperability model

Message oriented communication using platform dependent techniques and middle-wares are a traditional approach. Difficulty begins when dissimilar platforms are communicating together having different interfaces. Military organizations are also pursuing towards interoperability solutions. The goal to achieve is to interoperate interrelated mission critical systems running under the hood of one system called System of Systems (SoS) or often termed as Command Control Computer Communication and Intelligence (C4I) System. To achieve maximum interoperability we have introduced a common platform middleware that communicate on the bases of messaging, routing, invocation and mediation services. This paper covers and discussed a Service Oriented Architecture (SOA) based common view interoperability approach by integrating different dispersed applications together under a common-view. We will discuss the functionality, integration and implementation by adopter configuration and coupling.
The Important Role of TMPRSS2 Gene in Covid-19 and Prostate Cancer: In Silico Approach

Some studies have discovered a connection between prostate cancer and COVID-19. In this study, we evaluated the link between prostate cancer and COVID-19, contributing to elucidate the connection between TMPRSS2 and ACE2. We discovered 209 number of variants in TMPRSS2 gene, and 110 variants represent EA populations and 99 of them represent AA populations. Moreover, we found 23 suspected missense and 3 unknown variants. Then, linked genes to TMPRSS2 and ACE2 were found in our study. We investigated the expression level of TMPRSS2 and the results showed that it was very high in the prostate, colon, lung, kidney, and saliva-secreting gland. Also, the important role of the AR gene was revealed in addition to other oncogenes and tumor suppressor genes for prostate cancer by KEGG Pathway analysis. In conclusion, these results can highlight several molecular mechanisms of SARS-CoV-2, and also TMPRSS2, ACE2, and AR connection explains the high expression level of AR gene found in the male lung.
How to Effectively Collect and Process Network Data for Intrusion Detection?

The number of security breaches in the cyberspace is on the rise. This threat is met with intensive work in the intrusion detection research community. To keep the defensive mechanisms up to date and relevant, realistic network traffic datasets are needed. The use of flow-based data for machine-learning-based network intrusion detection is a promising direction for intrusion detection systems. However, many contemporary benchmark datasets do not contain features that are usable in the wild. The main contribution of this work is to cover the research gap related to identifying and investigating valuable features in the NetFlow schema that allow for effective, machine-learning-based network intrusion detection in the real world. To achieve this goal, several feature selection techniques have been applied on five flow-based network intrusion detection datasets, establishing an informative flow-based feature set. The authors’ experience with the deployment of this kind of system shows that to close the research-to-market gap, and to perform actual real-world application of machine-learning-based intrusion detection, a set of labeled data from the end-user has to be collected. This research aims at establishing the appropriate, minimal amount of data that is sufficient to effectively train machine learning algorithms in intrusion detection. The results show that a set of 10 features and a small amount of data is enough for the final model to perform very well.
Verification of dC(1) Parameter for Measuring the Effectiveness of a Personalized Ventilation System

An analysis of the ventilation effectiveness of a prototype personalized ventilation system of working places named PERMICS-LOS1 (Personal Microclimate System) was made, based on measurements of the air velocity field and of tracer gas concentrations using the decay method. The emphasis of the analysis was mainly on an experimental verification of a parameter based on the relative decrease of tracer gas concentration in the first minute of system operation dC(1) and on local ventilation efficiency using the local air-change index ∊L. A system analysis was made for several different operating regimes of personalized ventilation, where changes in air quantity and the direction of supplied air in the breathing zone were applied. The results of the experimental analysis were statistically evaluated, compared, and included in the existing database of previous research for use as supplementary values. The performed analysis has confirmed previous findings as well as the connection between the dC(1) parameter and ventilation effectiveness parameters, especially with the local air-change index.
Two-Signal Interaction in a Logarithmic IF Amplifier

For a suitable mathematical model of a logarithmic IF amplifier the signal suppression and intermodulation due to a second signal are found in closed form for a variety of cases. When at least one of the inputs is very strong the results agree with those for ideal limiting. In an appendix the assumptions underlying the mathematical model are examined. The approach presented is applicable to any bandpass nonlinearity.
Metrics Analysis Framework of Control and Management System for Resilient Connected Community Microgrids

This paper proposes a novel metrics analysis of the control and management system for an efficient and resilient post-hurricane integrated recovery framework. To enhance the resiliency of networked-microgrids (MGs), resources such as mobile emergency resources (MERs), electric vehicles (EVs), and energy storage systems (ESSs) associated with the reconfiguration strategy are utilized to decrease blackouts to a minimum time. In the proposed method, the local power-flow path is actively altered by the network reconfiguration. This capability allows restoring critical loads and minimizing the energy not supplied (ENS) to the local consumers. Islanded loads that need truck-mounted MERs are simultaneously determined through optimal scheduling. The role of MERs is to deliver power to the islanded load regarding optimal routes. To produce optimal routes and to avoid out-of-service roads, the well-known Dijkstra's algorithm is used in this study. The proposed method aims to maximize system resiliency through the integrated single-objective optimization problem, associated with evaluating the metrics, to assess the control system performance from a resiliency index perspective. Simulation results on a 69-bus test system indicate satisfactory performance and effectiveness of the proposed method.
