Wage Cyclicality under Different Regimes of Industrial Relations
2010
Since there is scant evidence on the role of industrial relations in wage cyclicality, this paper analyzes the effect of collective wage contracts and of works councils on real wage growth. Using linked employer-employee data for western Germany, we find that works councils affect wage growth only in combination with collective bargaining. Wage adjustments to positive and negative economic shocks are not always symmetric. Only under sectoral bargaining there is a (nearly symmetric) reaction to rising and falling unemployment. In contrast, wage growth in establishments without collective bargaining adjusts only to falling unemployment and is unaffected by rising unemployment.
MCC1019, a selective inhibitor of the Polo-box domain of Polo-like kinase 1 as novel, potent anticancer candidate
2019
Polo-like kinase (PLK1) has been identified as a potential target for cancer treatment. Although a number of small molecules have been investigated as PLK1 inhibitors, many of which showed limited selectivity. PLK1 harbors a regulatory domain, the Polo box domain (PBD), which has a key regulatory function for kinase activity and substrate recognition. We report on 3-bromomethyl-benzofuran-2-carboxylic acid ethyl ester (designated: MCC1019) as selective PLK1 inhibitor targeting PLK1 PBD. Cytotoxicity and fluorescence polarization-based screening were applied to a library of 1162 drug-like compounds to identify potential inhibitors of PLK1 PBD. The activity of compound MC1019 against the PLK1…
Traditional Chinese herbal medicine at the forefront battle against COVID-19: Clinical experience and scientific basis.
2020
Abstract Background Throughout the 5000-year history of China, more than 300 epidemics were recorded. Traditional Chinese herbal medicine (TCM) has been used effectively to combat each of these epidemics’ infections, and saved many lives. To date, there are hundreds of herbal TCM formulae developed for the purpose of prevention and treatment during epidemic infections. When COVID-19 ravaged the Wuhan district in China in early January 2020, without a deep understanding about the nature of COVID-19, patients admitted to the TCM Hospital in Wuhan were immediately treated with TCM and reported later with >90% efficacy. Approach We conducted conduct a systematic survey of various TCM herbal pre…
Simulation and experimental validation of multicarrier PWM techniques for three-phase five-level cascaded H-bridge with FPGA controller
2017
The FPGA represents a valid solution for the design and implementation of control systems for inverters adopted in many fields of power electronics because of its high flexibility of use. This paper presents an overview and an experimental validation of the MC SPWM techniques for a three-phase, five-level, cascaded H-Bridge inverter with FPGA controller-based. Several control algorithms are here implemented by means of the VHDL programming language and the output voltage waveforms obtained from the main PWM techniques are compared in terms of THD%. Simulation and experimental results are analyzed, compared and discussed.
Classifier Optimized for Resource-constrained Pervasive Systems and Energy-efficiency
2017
Computational intelligence is often used in smart environment applications in order to determine a user’scontext. Many computational intelligence algorithms are complex and resource-consuming which can beproblematic for implementation devices such as FPGA:s, ASIC:s and low-level microcontrollers. Thesetypes of devices are, however, highly useful in pervasive and mobile computing due to their small size,energy-efficiency and ability to provide fast real-time responses. In this paper, we propose a classi-fier, CORPSE, specifically targeted for implementation in FPGA:s, ASIC:s or low-level microcontrollers.CORPSE has a small memory footprint, is computationally inexpensive, and is suitable for…
An Embedded Biometric Sensor for Ubiquitous Authentication
2013
Communication networks and distributed technologies move people towards the era of ubiquitous computing. An ubiquitous environment needs many authentication sensors for users recognition, in order to provide a secure infrastructure for both user access to resources and services and information management. Today the security requirements must ensure secure and trusted user information to protect sensitive data resource access and they could be used for user traceability inside the platform. Conventional authentication systems, based on username and password, are in crisis since they are not able to guarantee a suitable security level for several applications. Biometric authentication systems…

Iekļaujošās izglītības īstenošana Valdorfa bērnudārzā
2019
Diplomdarba mērķis ir izpētīt iekļaujošās izglītības īstenošanu valdorfa pirmsskolas izglītības iestādē. Mērķa sasniegšanai tiek pētīta iekļaujošās izglītības būtība, tās formas un metodes, pētīta Valdorfpedagoģijas būtība un bērna loma tajā. Noslēgumā pētīti iekļaujošās izglītības indikatori un izzināti nosacījumi, lai iekļaujošās izglītības īstenošana Valdorfa bērnudārzā noritētu sekmīgi. Savā diplomdarbā autore apskata iekļaujošās izglītības iespējas tieši Valdorfpedagoģijā, kā tā īstenojas un cik lielas izredzes paveras uz pozitīvu rezultātu. Vai katram bērnam tā der un kas ir jāņem vērā gan pedagogiem, gan vecākiem. Autore apskata iekļaujošās izglītības būtību, kā tā īstenojas bērnudār…
Ritma nozīme pirmsskolas izglītības iestādes pedagoģiskajā procesā: Valdorfpedagoģijas pieeja

A new control system prototype for the energy production maximization of a unequally irradiated PV system
2011
This paper deals with the mismatch effect due to a unequally irradiation on a PV (PhotoVoltaic) system. The mismatch effect due to the partial shading of a PV module can be limited thanks to the installation of both bypass and block diodes. Unfortunately, this solution cannot fully solve the disvantages related to the mismatch effect. The Authors, in previous papers [1, 2], have theoretically demonstrated that the mismatch effect can be solved by changing the parallel/series connections of the modules of a PV system, taking into account each module radiating condition. This paper represents a first step of the experimental development of the above mentioned theoretical result. Specifically,…
