Giant magnetocaloric effect for (Mn, Fe, V)2(P, Si) alloys with low hysteresis

Lai, J. (author), Huang, B. (author), You, X. (author), Maschek, M. (author), Zhou, Guofu (author), van Dijk, N.H. (author), Brück, E.H. (author)

The Fe₂P type Mn–Fe–P–Si alloys exhibit a giant magneto-elastic first-order transition, but the large hysteresis limits their performance. Crystal structure evolution and magnetocaloric performance were investigated by varying the Mn and Fe contents at a constant V substitution of 0.02 in Fe₂P-type (Mn_1.17-xFe...

Using sky-classification to improve the short-term prediction of irradiance with sky images and convolutional neural networks

Martinez Lopez, V.A. (author), van Urk, G.A. (author), Doodkorte, P.J.F. (author), Zeman, M. (author), Isabella, O. (author), Ziar, H. (author)

Clouds moving in front or away from the sun are the leading cause of irradiance variability. These variations have a repercussion on the electricity production of photovoltaic systems. Predicting such changes is essential for proper control of these systems and for maintaining grid stability. Images from the sky have proven to help with short...

Multiplayer boycotts in convex games

Fokkink, R.J. (author), de Munnik, J.C. (author)

We extend the notion of boycotts between players in cooperative games to boycotts between coalitions. We prove that convex games offer a proper setting for studying these games. Boycotts have a heterogeneous effect. Individual players that are targeted by many-on-one boycotts suffer most, while non-participating players may actually benefit...

Optimal parameter estimation of shaped phase objects

Villegas, Arturo (author), Passos, M. H.M. (author), Pereira, S.F. (author), Torres, J. (author)

We show a general method to estimate with optimum precision, i.e., the best precision determined by the light-matter interaction process, a set of parameters that characterize a phase object. The method is derived from ideas presented by Pezze et al. [Phys. Rev. Lett. 119, 130504 (2017)0031-900710.1103/PhysRevLett.119.130504]. Our goal is to...

Mo, J. (author), LI, J. (author), Zhang, Y. (author), Romijn, J. (author), May, Alexander (author), Erlbacher, Tobias (author), Zhang, Kouchi (author), Vollebregt, S. (author)

In this work, a highly linear temperature sensor based on a silicon carbide (SiC) p-n diode is presented. Under a constant current biasing, the diode has an excellent linear response to the temperature (from room temperature to 600°C). The best linearity (coefficient of determination ${R}^{{2}}$ = 99.98%) is achieved when the current density...

van der Werf, I. (author), Dol, H. S. (author), Blom, K. (author), Heusdens, R. (author), Hendriks, R.C. (author), Leus, G.J.T. (author)

In this paper, we show the mathematical equivalence of two popular modulation schemes: OSDM and OTFS. The former is mainly used in underwater acoustic communications, while the latter scheme is a promising modulation technique in radio-frequency communications. Although literature suggests a link between the two modulation schemes by connecting...

Silicon heterojunction (SHJ) solar cells have achieved a record efficiency of 26.81% in a front/back-contacted (FBC) configuration. Moreover, thanks to their advantageous high V_OC and good infrared response, SHJ solar cells can be further combined with wide bandgap perovskite cells forming tandem devices to enable efficiencies well...

This paper proposes two modulation schemes for Dual Active Bridge (DAB) converters, with the aim of maximizing Zero Voltage Switching (ZVS) operation over a wide operational range. The first is a ZVS-optimized constant frequency modulation scheme, constructed based on the boundary conditions of ZVS operation. This scheme maximizes the number...

Copper Nanoparticle Sintering Enabled Hermetic Packaging With Fine Sealing Ring for MEMS Application

Hu, D. (author), Shah, M.B. (author), Fan, J. (author), Vollebregt, S. (author), Zhang, Kouchi (author)

Driving by the increased demand for hermetic packaging in the more than Moore (MtM) roadmap, a Cu nanoparticle sintering-enabled hermetic sealing solution was developed with a small-size sealing ring. The developed technology simplifies microfabrication and requires less surface roughness using a sinterable Cu nanoparticle paste. A 50μm size...

HAT: haplotype assembly tool using short and error-prone long reads

Shirali Hossein Zade, R. (author), Urhan, A. (author), Assis de Souza, A. (author), Singh, A. (author), Abeel, T.E.P.M.F. (author)

Motivation: Haplotypes are the set of alleles co-occurring on a single chromosome and inherited together to the next generation. Because a monoploid reference genome loses this co-occurrence information, it has limited use in associating phenotypes with allelic combinations of genotypes. Therefore, methods to reconstruct the complete...

Characterization of low-loss hydrogenated amorphous silicon films for superconducting resonators

Buijtendorp, Bruno T. (author), Bueno, Juan (author), Thoen, David (author), Murugesan, Vignesh (author), Sberna, P.M. (author), Baselmans, J.J.A. (author), Vollebregt, S. (author), Endo, A. (author)

Superconducting circuit elements used in millimeter-submillimeter (mm-submm) astronomy would greatly benefit from deposited dielectrics with small dielectric loss and noise. This will enable the use of multilayer circuit elements and thereby increase the efficiency of mm-submm filters and allow for a miniaturization of microwave kinetic...

Aims. Future actively cooled space-borne observatories for the far-infrared, loosely defined as a 1-10 THz band, can potentially reach a sensitivity limited only by background radiation from the Universe. This will result in an increase in observing speed of many orders of magnitude. A spectroscopic instrument on such an observatory requires...

An algorithm for reconstructing level-2 phylogenetic networks from trinets

van Iersel, L.J.J. (author), Kole, Sjors (author), Moulton, Vincent (author), Nipius, L. (author)

Evolutionary histories for species that cross with one another or exchange genetic material can be represented by leaf-labelled, directed graphs called phylogenetic networks. A major challenge in the burgeoning area of phylogenetic networks is to develop algorithms for building such networks by amalgamating small networks into a single large...
