description: In recent years, there have been quite a few attempts to apply intelligent techniques to financial trading, i.e., constructing automatic and intelligent trading framework based on historical stock price. Due to the unpredictable, uncertainty and volatile nature of financial market, researchers have also resorted to deep learning to construct the intelligent trading framework. In this paper, we propose to use CNN as the core functionality of such framework, because it is able to learn the spatial dependency (i.e., between rows and columns) of the input data. However, different with existing deep learning-based trading frameworks, we develop novel normalization process to prepare the stock data. In particular, we first empirically observe that the stock data is intrinsically heterogeneous and bursty, and then validate the heterogeneity and burst nature of stock data from a statistical perspective. Next, we design the data normalization method in a way such that the data heterogeneity is preserved and bursty events are suppressed. We verify out developed CNN-based trading framework plus our new normalization method on 29 stocks. Experiment results show that our approach can outperform other comparing approaches.

description: Thin film solar cells made from the directly absorbing chalcopyrite semiconductor Cu(In,Ga)(S,Se)2
(CIGSSe) have a high absorption capacity in a broad spectral range of the solar spectrum. Volume production of
CIGSSe modules has started because of their favorable attributes, e.g. low cost and good efficiency. We characterize
these solar cells cut to a lab scale via admittance spectroscopy (AS) to obtain a better understanding of electronic bulk
effects and the nature of defect states. With AS we can determine the trap parameters (activation energy, capture
cross section and defect concentration) in the active layer of the solar cells. An energetic profile of the defects was
identified by varying the level of the reverse voltage. In addition it is possible to distinguish between bulk and surface
defects.

description: Spectral manipulation has increasingly established as a common method in audio editing. Based on the analytical visualization of audio material as a spectrogram, it offers interactive methods that are visually comprehensible. Consequently, it can be used to extend methods of music production by discovering novel techniques or by revisiting known ones. Thereby, granular synthesis has high potential in gaining functionality when thought and used in a spectral domain interface. Here, granular spectral synthesis is proposed and how it takes advantage is discussed.

description: The metastable current-voltage characteristics on Cu(In,Ga)Se2 (CIGS) solar cells with controlled
conduction band offset (CBO) values of window/CIGS layers were investigated. The CBO value was controlled by
changing the band gap of a (Zn,Mg)O (ZMO) window layer. The metastable behaviors were observed in the CIGS
solar cells when the conduction band of ZMO is higher than that of CIGS. The metastability becomes severe with
increasing the CBO value. The quantum efficiency measurement revealed that the metastability in current-voltage
curves were due to the metastable change of the photocurrent collection. The model of the metastability is discussed
with simulated energy band diagrams.

description: The correlation function between two Polyakov loops encodes the free-energy shift due to a pair of separated colour conjugated sources in the hot QCD medium. This is analyzed in terms of a novel Källén-Lehmann spectral representation for the separating distance, implying an increasing and concave free-energy at all temperatures. We express the heavy $\bar{Q} Q$ free-energy shift below the phase transition in QCD in terms of colour neutral purely hadronic states with no explicit reference to quarks and gluons. Good agreement with lattice data is achieved when considering the avoided crossing mechanism underlying string breaking and with standard quenched values of the string tension known from charmonium and bottomonium phenomenology. We also address the role of the corresponding entropy shift and its renormalization group properties.

description: Abstract:
 Mental abuse can have devastating effects on a person’s mental health, self-esteem, and confidence. It can cause a person to feel scared, worthless, and helpless. It can also leave victims feeling isolated, alone and vulnerable. Mental abuse can take many forms such as shaming, bullying or humiliation. It is often more difficult to recognize than physical abuse because it is less visible and may not have the same physical consequences. Victims of mental abuse may experience feelings of worthlessness, inferiority complex and other forms of mental trauma due to the psychological torture they are subjected to by their abuser. The environmental impact of mental abuse should not be taken lightly as it often has a lasting effect on victims who may struggle to cope with their feelings for years afterwards. Mental abuse should be addressed swiftly in order to prevent long-term damage from occurring. The effects of mental abuse are far worse than physical abuse as it can lead to long-term psychological damage and trauma. It is important to recognize the signs of mental abuse and seek help from professionals if needed. People who are struggling with mental trauma should never feel ashamed to ask for help. Therapy can help victims to heal from the effects of mental abuse and learn coping strategies. Through therapy sessions, victims are able to explore their feelings and build healthier relationships with others. Therapists also help victims understand how their environment affects them emotionally and teach them how to take control of their lives again by developing healthy habits. With help from these therapies, victims can slowly but surely regain a sense of worth and empowerment.

description: High-quality single crystals of CuInSe2 with near-stoichiometric elemental compositions, grown
by the Bridgman method, were irradiated by 6 MeV electrons with doses from 51015 to 1018 cm-2. The crystals
were studied before and after irradiation using photoluminescence (PL) at a temperature of 4.2 K. The PL
spectra, measured before the irradiation, reveal a number of sharp and well resolved lines associated with freeand
bound-excitons. The lower energy region of the spectra also reveals broader peaks related to band-impurity,
donor-acceptor pair recombination and their phonon replicas. The irradiation resulted in a reduction of the
intensity of the free- and bound-excitons observed in the non-implanted material. Such a reduction is observed
for quite low doses of 51015 cm-2. Irradiation also induces new sharp PL lines W1 at 1.03, W2 at 1.01 eV and W3
eV at 0.99 eV below the free-exciton emission. Two deeper broad bands, associated earlier with the acceptortype
defects, interstitial selenium (Sei) and copper on indium site (CuIn), have become more intense suggesting
an increase in the concentration of these defects due to irradiation.

description: In this work, we study the localization of the vector gauge field in two five-dimensional braneworlds generated by scalar fields coupled to gravity. The sine-Gordon like potentials are employed to produce different thick brane setups. A zero mode localized is obtained, and we show the existence of reverberations with the wave solutions indicating a quasi-localized massive mode. More interesting results are achieved when we propose a double sine-Gordon potential to the scalar field. The resulting thick brane shows a more detailed topology with the presence of an internal structure composed by two kinks. The massive spectrum of the gauge field is revalued on this scenario revealing the existence of various resonant modes. Furthermore, we compute the corrections to Coulomb law coming from these massive KK vector modes in these thick scenarios, where is concluded that the dilaton parameter regulates these corrections.

description: A novel and advanced photovoltaic concentrator optic is presented comprising a Fresnel lens and a
dielectric solid RXI as a secondary optical element, both with free-form surfaces (i.e. neither rotational nor linear
symmetry). The RXI secondary is designed with the Simultaneous Multiple Surface (SMS) design method of
Nonimaging Optics. In the secondary optics rays undergo refraction (R), reflection (X) and total internal reflection
(I), so SMS nomenclature [2] for the device is RXI assigning letters to each surface that deflects rays. This is the first
time the RXI-type geometry has been applied to design a photovoltaic secondary element. The LPI patented Fresnel-
RXI Köhler concentrator [1] produces both the desired light concentration with high tolerance (high acceptance
angle) as well as high irradiance uniformity on the solar cell achieved by Köhler integration method. The optical
performance of the FRXI device (F denotes a Fresnel lens surface) will be presented as well as comparison with other
conventional Fresnel-based CPV concentrators and application of the designed system.

description: Numerical simulation of devices plays a crucial role in their design, performance prediction, and
comprehension of the fundamental phenomena ruling their operation. Here, we present results obtained using the
code D-AMPS-1D, that was conveniently modified to consider the particularities of III-V solar cell devices. This
work, that is a continuation of a previous paper regarding solar cells for space applications, is focused on solar
cells structures than find application for terrestrial use under concentrated solar illumination. The devices were
fabricated at the Solar Energy Institute of the Technical University of Madrid (UPM). The first simulations
results on InGaP cells are presented. The influence of band offsets and band bending at the window-emitter
interface on the quantum efficiency was studied. A remarkable match of the experimental quantum efficiency
was obtained. Finally, numerical simulation of single junction n-p InGaP-Ge solar cells was performed.

description: Rate-limiting oxidation steps of acidic silicon etching processes were successfully simulated by reactions of
hydrogen terminated silicon surfaces with solvents (H2SO4), relevant oxidants (HNO3, NO+) and their reduction intermediates
(NO). Oxidation is initiated by generation of defect electrons in the silicon valence band (h+
VB) in order to break Si-Si
backbonds (DR/FT-IR-spectroscopy measurements). Oxidizing agents are quickly reduced one or two oxidation states,
analyzed by FT-IR- and 14N-NMR-spectroscopic investigations. DR/FT-IR analysis indicated that Si-H bonds are successively
attacked by protons (divalent electrochemical mechanism: H2, Raman-spectroscopy)) or oxidants
(FT-IR-spectroscopy). 1H-NMR- and 14N-NMR-spectroscopic measurements demonstrated general absence of quantitative
ammonium ion formation.

description: The “Restriction of Hazardous Substances in Electronics and Electrical Equipments” (RoHS) is regulating the use of
hazardous substances such as heavy metals and others in electronics. At the moment the compliance of crystalline silicon
solar cells to RoHS is not required by law. However, a revision of the RoHS regulation is intended and the PV branch will
probably be included. Up to now, lead is a compound of cell metallization and a main content of the interconnection solder.
It curtails the environmentally-friendly image of the photovoltaic industry as a driving factor in the renewable energy world.
In fact, parts of the RoHS goal have already been achieved: heavy metal free compositions are already available for example
cadmium free pastes and lead-free solders. Due to the difficulties in soldering applications a widespread usage is not in sight.
In the paper an overview of different efforts and approaches to achieve RoHS-compatible cell metallization by wet-chemical
processes with and without seed layers as well as interconnects is given.
A comparison of these possibilities of cell metallization will be presented considering of RoHS requirements, high volume
production, enhancement of efficiency and solderability as well as he cost and potential shortage of certain resources. CiS
developments referring to the discussed conditions will be analyzed. Recommendations for the RoHS-compatible cell
metallization will be made.
Compared to cell metallization effects of interconnection solutions on RoHS compliance seem to be more significant.
Currently, different solutions for cell metallization by plating can be offered, however the soldering process itself seems to be
optimized only for the utilization of tin-lead soldered ribbons. Of course, the soldering of thin wafers of 160 μm and less is a
challenge. When using lead-free solders, overcoming this challenge it seems to be almost impossible. First recommendations
for lead-free soldering were presented at the 22nd PVSEC in Milano. Meanwhile, our research continued and recent results
will be presented primarily concerning ribbon quality. A new ribbon type with enhanced quality and fitting accuracy will be
introduced and soldering results will be presented.

description: Current density-voltage (J-V) characteristics of homogeneous CuIn(Se1-y,Sy)2/CdS/ZnO devices were evaluated under standard test conditions (STC). The two-diode model was used to analyse the J-V characteristics of devices. Devices manufactured from homogeneous CuIn(Se1-y,Sy)2-based chalcopyrite alloys, 0 ≤ y ≤ 0.7, and incorporating the standard window layer, demonstrated average open-circuit voltages (Voc) and short-circuit current densities (Jsc) values of 480 and 600 mV, and 15 and 32 mA.cm-2, respectively. A plot of the open-circuit voltage as function of the band-gap revealed an experimental relationship of: Voc = (Eg/q–0.6) mV for Eg < 1.3 eV. The fill factor (FF) values varied between 30 and 59% and device efficiencies between 3 and 10%, depending on the S/Se anion ratio. Series and shunt resistance for the devices as function of the S/Se anion ratio varied for series resistance between 0.4 and 1.0  and shunt resistance between 40 and 350 . The diode quality factors of the devices varied between 1.5 and 3 depending on the S/Se anion ratio. The high diode quality factors (n > 1.5) indicate that the current transport mechanism in the devices was dominated by recombination in the depletion layer. Keywords: CuIn(Se,S)2, homogeneous, chalcopyrite, open-circuit voltage, short-circuit current density, two-diode model.

description: We study the signatures of reionization and ionizing properties of the early galaxies in the cross-correlations between the 21cm emission from the spin-flip transition of neutral hydrogen (HI) and the underlying galaxy population, in particular a sub-population of galaxies visible as Lyman Alpha Emitters (LAEs). With both observables simultaneously derived from a $z\simeq6.6$ hydrodynamical simulation (GADGET-2) snapshot post-processed with a radiative transfer code (pCRASH) and a dust model, we perform a parameter study and aim to constrain both the average intergalactic medium (IGM) ionization state ($1-\langle χ_{HI} \rangle$) and the reionization topology (outside-in versus inside-out). We find that in our model LAEs occupy the densest and most-ionized regions resulting in a very strong anti-correlation between the LAEs and the 21cm emission. A 1000h SKA-LOW1 - Subaru Hyper Suprime Cam experiment can provide constraints on $\langle χ_{HI} \rangle$, allowing us to distinguish between IGM ionization levels of 50%, 25%, 10% and fully ionized at scales $r<10$ comoving Mpc (assuming foreground avoidance for SKA). Our results support the inside-out reionization scenario where the densest knots (under-dense voids) are ionized first (last) for $\langle χ_{HI} \rangle >= 0.1$. Further, 1000h SKA-LOW1 observations should be able to confirm the inside-out scenario by detecting a lower 21cm brightness temperature (by about 2-10 mK) in the densest regions ($> 2$ arcminute scales) hosting LAEs compared to lower-density regions devoid of them.

description: Imec has developed a new technology concept to integrate and interconnect back-contact solar cells
into modules, based on embedding cells in silicone on top of a glass substrate. This so-called i-module (interconnect
module) technology aims at an improved optical performance and reliability, combined with an increased
throughput for module manufacturing, through the use of silicones and a module-level interconnection that
eliminates string handling. One of the additional advantages is that the technology could therefore be suitable for
integrating very thin cells into modules.
The paper will first elaborate on the process flow, its background and motivation. A lot of options are still open for
consideration, but technical feasibility is demonstrated for two distinct implementations. Materials and processing
are discussed for these cases, as well as the resulting module measurements. Then the methodology behind the
followed reliability approach is discussed on a general level and some first results on accelerated reliability testing
and outdoor weathering are shown. Finally, a view on future developments is given as an outlook.
Uplink FBMC/OQAM-based Multiple Access Channel: Distortion Analysis under Strong Frequency Selectivity

Year: 2016
Subjects: subject: Information Theory (cs.IT)

description: This paper computes the distortion power at the receiver side of an FBMC/OQAM-based OFDMA uplink channel under strong frequency selectivity and/or user timing errors. More precisely, it provides a distortion expression that is valid for a wide class of prototype pulses (not necessarily perfect-reconstruction ones) when the number of subcarriers is sufficiently large. This result is a valuable instrument for analyzing how users interfere to one another and to justify, formally, the common choice of placing an empty guard band between adjacent users. Interestingly, the number of out-band subcarriers contaminated by each user only depends on the prototype pulses and not on the channel nor on the equalizer. To conclude, the distortion analysis presented in this paper, together with some simulation results for a realistic scenario, also provide convincing evidence that FBMC/OQAM-based OFDMA is superior to classic circular-prefix OFDMA in the case of asynchronous users.

description: Suppose $j_N(τ)$ and $j_N^{*}(τ)$ are the Hauptmoduln of the congruence subgroup $Γ_0(N)$ and the Fricke group $Γ^{*}_0(N)$, respectively. In [7], the authors predicted that, like Klein's $j$-function, the Fourier coefficients of $j_N(τ)$ and $j_{N}^{*}(τ)$ in some arithmetic progression are both even and odd with density $\frac{1}{2}$. In this article, we can find some arithmetic progression of $n$ where the Fourier coefficients of $j_6(τ)$ (resp. $j_6^{*}(τ)$ and $j_{10}(τ)$) are almost always even. Furthermore, using Hecke eigenforms and Rogers-Ramanujan continued fraction, we obtain infinite families of congruences for $j_6(τ)$, $j_6^{*}(τ)$, $j_{10}(τ),$ and $j_{10}^{*}(τ)$.

description: Silicon solar cells for concentrator applications tend to be small in size due to the use of light focusing
optics and minimization of material usage. As cells become smaller, isolation of cells at their edges therefore
becomes relatively more important in terms of both accuracy and cell performance. A novel isolation technique
designed to address these issues is presented, and demonstrated with LGBC cells (Laser Grooved Buried Contacts)
manufactured in the Narec pilot production line. As concentration is increased, cells with our Front Dicing
Technique (FDT) increasingly outperform cells having our standard isolation thanks to gains in VOC and FF. Internal
Quantum Efficiency (IQE) remains high at short wavelengths and is improved in the long wavelength region. There
is no net increase in the number of processing steps and no additional resource consumption, therefore providing an
easily implemented route to reducing cost per Watt.

Moreover, since we are able to construct symmetric solutions to the problem, when $N=2$ with prescribed growth arbitrarily close to the critical one, we can conclude that the asymptotic bound found is optimal. Finally, we prove existence of genuinely higher dimensional solutions, when $N\geq 3$.

description: Control rooms are facilities of central importance in many safetycritical domains (e.g., rescue services, traffic management, power supply). At the same time, they are characterized by a complex IT infrastructure that can only be integrated and adapted to a limited extent for research activities in the area of human-computer interaction. Previous work has already shown that virtual reality simulators of control rooms can be a suitable tool for these purposes. However, the solutions to date are very domain-specific, which makes it difficult to transfer knowledge and also to test aspects that are not primarily domain-specific (e.g., multimodal forms of interaction). This paper presents the concept of a domainindependent control room simulator and the development status regarding two use cases (build mode, simulation mode). Finally, further development and use of this approach are discussed.

In this work we explore the use of Signed Distance Fields (SDF) for representing and visualising 3D wavetables. SDF representations allow intuitive interactive sculpting and animation of 3D forms. We demonstrate different methods for transforming these forms into sound in real-time, by intersecting arbitrary 2D surfaces with the 3D forms and interpreting the results as sound, in both time and frequency domains. This extends the concept of wavetable synthesizers, and as SDFs lend themselves to real-time, immersive display and interaction through motion and gesture, the technique can be used to construct novel interfaces for musical expression.

description: The new generations of space satellites need more power and have more mass constraints with respect to
the past. High efficiency solar cells based on III-V compounds are the best approach to increase specific power and
lifetime of the solar arrays. InGaP/InGaAs/Ge triple junction(CTJ) solar cells with a size of 26.5 cm2, thickness of 140
μm and AM0 efficiency class 28%(CTJ28%), were utilized by Kvant on semi-rigid substrates for the manufacturing of
several solar arrays. (1), (3) These solar cells are manufactured by CESI with a large MOCVD epitaxial reactor, VEECO
E450 type, suitable to hold up to thirteen, 4 inch wafers, per run. More recently the solar cell structure has been
optimised by a fine tuning of the electrical field inside the active regions (patent pending design) and conversion
efficiency above 30% has been achieved. The improved TJ cell, thanks to the optimised structure, shows a higher
hardness to electron irradiation with 1 MeV electrons in comparison to the CTJ28% .This paper summarizes the results
of the manufacturing and tests campaign performed at bare cell level and provides details on the future application of
improved solar cells in the solar array manufacturing for the next generation of the Russian spacecraft. This report
summarises the most recent results concerning the development of SA panels based on the CTJ28% solar cells and the
semi-rigid (mesh and string) frame technology for use on spacecrafts operating in LEO and MEO. The results of the Solar
arrays (SA) ground workout, the ground tests, as well as the results of final electrical characterization are discussed.

description: In this paper, we present an innovative texturing method to form uniform porous textures on multicrystalline
silicon wafers in alklaine solutions by anodic polarization. As-cut boron doped multicrystalline silicon wafers were exposed
to strong KOH solution and polarised anodically to potentials above the stability potential of water. The etching parameters
such as concentration, temperature, applied potential and exposure time are changed in a systematic way in order to obtain a
uniformly textured surface. The textured surfaces were analysed by SEM and reflectance measurements. It is shown that after
polarization, a macroporous layer containing nano size pores is formed on all the grains. This texture resemblences the
texutures formed by isotropic etchants. Reflectance of the textured surfaces was measured in the 350-1100 nm wavelength
range, and the average reflectance on an uniformly textured surface is around 50% lower than the reflectance measured on
the texures formed by conventional wet chemical etching.

description: With modernizing traffic, a rise of automated vehicles (AVs) is expected. As AVs potentially need to communicate their intentions, external human-machine interfaces (eHMIs) seem to be an appropriate solution. While automotive research progresses quickly, people with special needs (PSN) are vastly underrepresented. With an aging population due to demographic changes and advances in medical treatments and with the stride towards equality and accessibility, the needs of these groups also have to be considered in the automotive domain. We provide an inclusive platform for interdisciplinary exchange on current and future topics, especially for academia, industry, and politics. This enables different perspectives with particular (but not exclusive) regard to user experience (UX) and psychology, product design, legislative concerns and, thus, support the communication and potentially founding of new topic streams. The aim is to create new interdisciplinary networks and collaborations to make future developments on vehicle-to-human (V2H) communication more inclusive.

description: Supermassive black holes observed at high redshift $z\gtrsim6$ could grow from direct collapse black holes (DCBHs) with mass $\sim10^5\,M_{\odot}$, which result from the collapse of supermassive stars (SMSs). If a relativistic jet is launched from a DCBH, it can break out of the collapsing SMS and produce a gamma-ray burst (GRB). Although most of the GRB jets are off-axis from our line of sight, we show that the energy injected from the jet into a cocoon is huge $\sim10^{55-56}\,{\rm{erg}}$, so that the cocoon fireball is observed as ultra-luminous supernovae of $\sim10^{45-46}\rm{\,erg\,s^{-1}}$ for $\sim5000 [(1+z)/16] \rm{\,days}$. They are detectable by the future telescopes with near infrared bands, such as, $Euclid$, $WFIRST$, $WISH$, and $JWST$ up to $z\sim20$ and $\sim 100$ events per year, providing a direct evidence of the DCBH scenario.

description: Glass has long been used for photovoltaic (PV) module covers and thin-film (TF) module substrates
and superstrates. These applications typically use float glass of soda-lime-silica composition and thickness > 3.2
mm. Thin specialty glass is being considered as a replacement for substrates and superstrates for dual-glass
laminated TF PV modules. This study focuses on module in-service stresses and their impact on mechanical
reliability when using thin specialty glass. Substrate and superstrate thicknesses as low as 0.7 mm were analyzed
using various support conditions. Hail impact tests were conducted according to IEC 61646 with standard ice balls
(25mm diameter at 23 m/sec). Wind loads as described in IEC 61646 were studied by finite element analysis.
Reliability analyses were performed using experimental results, modeled stress levels, initial glass strength, and
strength decrease over time (fatigue). This study concludes that thin specialty glass is reliable in a variety of
configurations. Wind load stresses increased systematically as glass thickness decreased. However, support
structure configuration showed a greater influence on stress and reliability levels than glass thickness. High speed
wind tests on full sized laminates with complete support structures provided validation of performance under
realistic conditions. Thin specialty glasses are shown to be a reliable option for TF PV module substrates and
superstrates.

description: Das Forschungsgebiet der Innovativen Computerbasierten Musikinterfaces umfasst inzwischen und mit Zunahme der Miniaturisierung und vereinfachten Integration von Sensorik und Aktorik eine Vielfalt von Themengebieten. Dazu gehören u.a. neuartige Musikinstrumente, interaktive und teils kooperative Multitouch Anwendungen, 3-D-Sound, Audio-Video-Installationen und Performances. Es finden sich vielfältige Möglichkeiten in konkreten Anwendungsgebieten, wie auch im rein künstlerischen Ausdruck. Im ICMI-Workshop 2022 möchten wir gern den gesamten Bereich »Musikalischer Interaktion« betrachten und sprechen die unterschiedlichsten Zielgruppen in diesem spannenden Gebiet an. In der Regelmäßigkeit unserer Workshops möchten wir gern ein Forum bieten, um neue Ansätze und Forschungsvorhaben zur Music Interaction vorzustellen und zu diskutieren. Dabei ist es das primäre Ziel, die unterschiedlichen Expertengruppen, die sich meist unabhängig voneinander mit dieser Thematik befassen, einander näher zu bringen und in einer gemeinsamen Veranstaltung Ideen, Experimente und Entwicklungen kennen zu lernen und sich auszutauschen. Der ICMI-Workshop wurde auf der MuC seit 2008 sieben Mal durchgeführt und war dort stark nachgefragt. Eine Übersicht der Vorträge / Papers der vergangenenWorkshops findet man unter www.icmi-workshop.org. Das Konzept des ICMI-Workshops beinhaltet einen Vortrag einer herausragenden Person des Forschungsund Anwendungsfelds als Keynotespeaker.

description: Serious searches for the weakly interacting massive particle (WIMP) have now begun. In this context, the most important questions that need to be addressed are: "To what extent can we constrain the WIMP models in the future?" and "What will then be the remaining unexplored regions in the WIMP parameter space for each of these models?" In our quest to answer these questions, we classify WIMP in terms of quantum number and study each case adopting minimality as a guiding principle. As a first step, we study one of the simple cases of the minimal composition in the well-tempered fermionic WIMP regime, namely the singlet-doublets WIMP model. We consider all available constraints from direct and indirect searches and also the predicted constraints coming from the near future and the future experiments. We thus obtain the current status, the near future prospects and the future prospects of this model in all its generality. We find that in the future, this model will be constrained almost solely by the future direct dark matter detection experiments (as compared to the weaker indirect and collider constraints) and the cosmological (relic density) constraints and will hence be gradually pushed to the corner of the coannihilation region, if no WIMP signal is detected. Future lepton colliders will then be useful in exploring this region not constrained by any other experiments.

description: The purpose of this study is to investigate the effects of wind loads on the structural deformation in a
high concentrated photovoltaic (HCPV) system by means of finite element analysis (FEA). A prototypical HCPV
system design being developed at National Central University was applied in the current study to analyze the
structural deformation under two different wind loading conditions, namely wind speeds of 6 and 17.2 m/s. The sun
tracking misalignment caused by structural deformation in the solar tracker and Fresnel lenses is also calculated. The
calculated maximum values of misalignment are 0.19o and 0.48o for wind speeds of 6 and 17.2 m/s, respectively.
These values are less than the acceptance angle 0.5o for a highly efficient HCPV system.

description: Die immer stärker digitalisierten Berufspraktiken, auch in kreativer Hinsicht, stellen für professionelle Musiker*innen und Instrumentalpädagog* innen weiterhin große Herausforderungen dar. Insbesondere neue MusikmachDinge nehmen bestehende musikalische Praktiken und Techniken auf und entwickeln sie spezifisch weiter. Dieser Prozess ist nicht störungsfrei und kann in der musikalischen Praxis zu Irritationen führen. Der Artikel fasst einige wichtige Konsequenzen zusammen, die die Autoren auf den Ebenen von Gendereffekten, Instrumentalmetaphern, Demokratisierungsversprechen und Problemlösestrategien bei Aneignungsprozessen identifiziert haben. Davon ausgehend plädieren sie für eine stärkere Berücksichtigung intersektionaler Aspekte bereits beim Herstellungsprozess von MusikmachDingen.
