description: S-matrix amplitudes for the electron-electron scattering are calculated in order to verify the quantum equivalence of dual models. We used an extended Quantum Electrodynamics with CPT-even Lorentz-violating kinetic and mass terms, which was used in a process of gauge embedding, known as Noether dualizationn method (NDM), in order to generate its gauge-invariant dual model. The physical equivalence was established at tree-level and the cross section was calculated to second order in the Lorentz-violating parameter.

description: We present the formation of uniform thick mesoporous layers in Ge produced by means of electrochemical
etching in highly concentrated HF electrolytes. The process is demonstrated on Ge wafers with 4 inch diameter, resulting in
spatially homogenous porous layers. The formation of mesoporous Ge always takes place simultaneously with a constant
dissolution of the already formed porous layer. The growth rate lies in the range of 0.071 to 2.7 nm/minute for etching
current densities in a range of 0.1 to 80 mA/cm2, while both etch and dissolution rates lie in the range of several μm/min. We
define the substrate usage as the ratio of growth rate and etch rate. It is used to determine the porous layer growth efficiency
and lies in the 0.2-2% range for anodic etching experiments. If the etching bias is alternated from anodic to cathodic
periodically, substrate thinning is avoided and usage increases up to 98%.

description: Angle-independent, narrowband emission is required for many optoelectronic devices, ranging from high-definition displays to sensors. However, emerging materials for electroluminescent devices, such as organics and perovskites, show spectrally broad emission due to intrinsic disorder. Coupling this emission to an optical resonance reduces the linewidth, but at the cost of inheriting the severe angular dispersion of the resonator. Strongly coupling a dispersionless exciton state to a narrowband optical microcavity could overcome this issue; however, electrically pumped emission from the resulting polaritons has been hampered by poor efficiencies. Here, we present a universal concept for polariton-based emission from state-of-the-art organic LEDs (OLEDs) by introducing an assistant strong coupling layer, thus avoiding quenching-induced efficiency losses. We realize red- and green-emitting, narrowband (FWHM <20 nm) and spectrally tuneable polaritonic OLEDs with up to 10% external quantum efficiency and high luminance (>20,000 cd m$^{-2}$ at 5 V). Optimizing cavity detuning and coupling strength allows to achieve emission with ultralow-dispersion (<10 nm spectral shift at 60° tilt). These results have significant implications for on-demand polariton emission and demonstrate the practical relevance of strong light-matter coupling for next-generation optoelectronics, particularly display technology.

description: The German joint project ‘Flexible Cu(In,Ga)Se2 (CIGSe) Thin Film Solar Cells for Space Applications’ is a national
initiative that aims at the development of a flexible, CIGSe based solar cell technology on polyimide foil with the
potential to realize extremely light generator concepts. For CIGSe absorber fabrication three types of technological
approaches have been taken into account: batch type multi-stage co-evaporation, in-line single-stage co-evaporation
and roll-to-roll co-evaporation. So far, interconnection of individual devices is achieved merely by a rivet based
method and is - in part - to be supplemented by monolithic and/or pseudo-monolithic integration. The current
maximum total area solar cell efficiency for a lab scale device is 15.9 % (0.95 cm2, AM1.5, with AR) and has been
certified by ISE, Freiburg. On a large area, standardized single device the maximum total area efficiency is 10.6 %
(31.2 cm2, AM 1.5, no AR) and is based on the industrial roll-to-roll process.

description: We propose new five-dimensional gauge theory descriptions of six-dimensional $\mathcal{N}=(1,0)$ superconformal field theories arising from type IIA brane configurations including an $ON^0$-plane. The new five-dimensional gauge theories may have $SO$, $Sp$, and $SU$ gauge groups and further broaden the landscape of ultraviolet complete five-dimensional $\mathcal{N}=1$ supersymmetric gauge theories. When we include an $O8^-$-plane in addition to an $ON^0$-plane, T-duality yields two $O7^-$-planes at the intersections of an $ON^0$-plane and two $O5^0$-planes. We propose a novel resolution of the $O7^-$-plane with four D7-branes in such a configuration, which enables us to obtain three different types of five-dimensional gauge theories, depending on whether we resolve either none or one or two $O7^-$-planes. Such different possibilities yield a new five-dimensional duality between a D-type $SU$ quiver and an $SO-Sp$ quiver theories. We also claim that a twisted circle compactification of a six-dimensional superconformal field theory may lead to a five-dimensional gauge theory different from those obtained by a simple circle compactification.

HOLOTYPE: AMNH 692459, adult male, collected at Inkerman, 19.45S, 147.29E (USBGN, 1957), Queensland, Australia, on 19 April 1907, by Wilfred Stalker. From the Mathews Collection (no. 3106) via the Rothschild Collection. COMMENTS: Mathews cited his catalog number of the holotype in the original description and gave the range as ‘‘ Queensland.’’ The holotype bears, in addition to Stalker’s original label and Mathews and Rothschild type labels, a ‘‘Figured’’ label, indicating that it was illustrated in Mathews (1924: pl. 523, top fig., opp. p. 388, text p. 392), where it is confirmed as the type of queenslandicus. The number ‘‘762’’ on the reverse of Stalker’s label refers to the number of this species in Mathews (1908). Ingram (1908: 476) reported on Stalker’s collection and listed this single specimen. No other Queensland specimens in AMNH from the Mathews Collection were collected before the 31 January 1912 publication date of queenslandicus.

description: Large-area (125x125 mm2) solar cells using standard CZ material and a close-to-industry front structure including a diffused POCl3 emitter, a SiNx:H anti-reflection coating and screen-printed contacts which were fine-line printed and thickened by light-induced silver plating were manufactured applying a dielectrically passivated and locally contacted rear structure. The rear passivation was achieved by a PECVD stack of SiOxNy:H and SiNx:H. The rear Al layer on top of the dielectric was screen-printed and co-fired with the front contacts. The local rear contacts were subsequently prepared by laser-firing.
The best dielectrically passivated LFC (Al-BSF reference) cell showed VOC=622 mV (614 mV), JSC=36.2 mA/cm2 (35.6 mA/cm2), FF=78 % (79 %) which ends up in an energy conversion efficiency of 17.5 % (17.4 %). The passivated LFC cell clearly outperforms the Al-BSF reference when looking at IQE data. Light microscope images and surface topography measurements of the front contacts are presented.

description: We propose a simple and generic construction of the variational tensor network operators to study the quantum spin systems by the synergy of ideas from the imaginary-time evolution and variational optimization of trial wave functions. By applying these operators to simple initial states, accurate variational ground state wave functions with extremely few parameters can be obtained. Furthermore, the framework can be applied to study spontaneously symmetry breaking, symmetry protected topological, and intrinsic topologically ordered phases, and we show that symmetries of the local tensors associated with these phases can emerge directly after the optimization without any gauge fixing. This provides a universal way to identify quantum phase transitions without prior knowledge of the system.

project where such standards will be defined together with the main European networks of renewable energies plant
industries. To achieve what the art.14 of the EU Directive requires education, training and dissemination efforts should be
carried out in all European countries following the example of the “QualiCert” partners. Some and small adjustments are
possible in order to take into account the different conditions in each EU countries considering just as the different typologies
of the application, the growth of market and its perspectives for long term (power to be installed, architectural needs of

tracking machine are identified. A practical process for learning the values of these variable parameters is described. The
results of practical on-going machine trials are presented. Using these techniques it is possible for an open loop tracking
system to achieve sub-degree accuracy without external feedback devices, accurate initial alignment or any physical
measurements.

description: The one- and two-photon scattering matrix S is obtained analytically for a one-dimensional waveguide and a point-like scatterer with N excited levels (generalized V -type atom). We argue that the two-photon scattering matrix contains sufficient information to distinguish between different level structures which are equivalent for single-photon scattering, such as a V -atom with N = 2 excited levels and two two-level systems. In particular, we show that the scattering with the V -type atom exhibits a destructive interference effect leading to two-photon Coupled-Resonator-Induced Transparency, where the nonlinear part of the two-photon scattering matrix vanishes when each incident photon fulfills a single-photon condition for transparency.

description: Life Cycle Assessment (LCA) studies on photovoltaic (PV) systems conducted so far primarily
investigated energy demands in PV manufacture, as with carbon fuels assumed in the ‘background’ high energy
consumption represents large emissions. Despite the relatively high energy demands of PV manufacture and the
assumption that this demand is served by mainly carbon fuels, however, a large number of previous LCA proved
emissions of PV to be as low as 30-60 g CO2-eq/kWh nonetheless. The larger the share of renewable energy systems in
the market, however, the less important also the energy-input related emissions become. In this case, the emissions that
occur solely during PV manufacture gain relevance. In this paper, we differentiate these so-called direct CO2-eq
emissions (related to only PV manufacture) from the indirect emission (related to the “background” energy supply) using
the ecoinvent database. Therefore, emissions associated to electricity consumed in PV manufacture are varied in our
analysis. Focussing exclusively on crystalline silicon PV we find a reduced carbon footprint of PV systems by about 50%
for assuming solely ‘green’ electricity (i.e., hydro-, wind- or PV electricity) is used in the entire PV manufacture chain.
In addition, we find that the eco-invent LCA data suggests transport related emissions to be of almost no relevance.
Differentiations concerning process-heat demand could not yet be investigated and should be matter of future
investigations, amongst which e.g. process-heat substitutable by electricity.

description: We show that any $n\times m$ matrix $A$ can be approximated in operator norm by a submatrix with a number of columns of order the stable rank of $A$. This improves on existing results by removing an extra logarithmic factor in the size of the extracted matrix. Our proof uses the recent solution of the Kadison-Singer problem. We also develop a sort of tensorization technique to deal with constraint approximation problems. As an application, we provide a sparsification result with equal weights and an optimal approximate John's decomposition for non-symmetric convex bodies. This enables us to show that any convex body in $\mathbb{R}^n$ is arbitrary close to another one having $O(n)$ contact points and fills the gap left in the literature after the results of Rudelson and Srivastava by completely answering the problem. As a consequence, we also show that the method developed by Guédon, Gordon and Meyer to establish the isomorphic Dvoretzky theorem yields to the best known result once we inject our improvements.

description: Past EUPVSEC, we presented our results concerning electron beam crystallized silicon thin film solar
cells on glass. The liquid phase crystallization process lead to grain sizes between several 100μm up to cm in length.
To provide necessary absorber doping, an amorphous intermediate layer of amorphous, boron doped silicon carbide is
deposited by sputtering on top of the pre-cleaned glass substrates. This layer full fills the function of a diffusion
barrier against the incorporation of residual impurities of the glass as well as a wetting agent for the liquid silicon to
prevent balling up. A higher purity of the used SiC-Target together with a reduced level of dopands, an absorber
Doping level NA of about 1016cm-3 could be realised, marking an ideal value for the given cell geometry. By
combining these polycrystalline silicon absorbers with an n-type amorphous hydrogenated silicon emitter, current
cells achieved open circuit voltages of up to 545mV as well as fill factors of 74% without any H2-passivation steps
nor defect annealing. This corresponds to an increase of Voc of 58mV compared to earlier cells with an absorber
dopant level NA of 1018 cm-3. The comparable short circuit current density of -12mA cm-2 indicates the need of an
effective light management concept for these cells, of which first results are presented.

description: We give a new definition of the semigroup C*-algebra of a left cancellative semigroup, which resolves problems of the construction by X. Li. Namely, the new construction is functorial, and the independence of ideals in the semigroup does not influence the independence of the generators. It has a group C*-algebra as a natural quotient. The C*-algebra of the old construction is a quotient of the new one. All this applies both to the full and reduced C*-algebras. The construction is based on the universal inverse semigroup generated by a left cancellative semigroup. We apply this approach to connect amenability of a semigroup to nuclearity of its C*-algebra. Large classes of actions of these semigroups are in one-to-one correspondence, and the crossed products are isomorphic. A crossed product of a left Ore semigroup is isomorphic to the partial crossed product of the generated group.

Neurophysiology of Mental Imagery and Reality Monitoring
Creators: name: Thomas, Pietruszewski
Publisher: name: Georgia State University
Year: 2022

description:
People with vivid imaginations are less accurate at identifying whether memories originated from experience or imagination than people with less vivid imaginations. This can be modeled as a similarity between the memory traces created during vivid imagination and perception, which causes source confusion during recall. The role of visual imagery in this process has been well established, but the role of auditory imagery remains unclear. fMRI data collected from an auditory/visual imagination task was analyzed to determine the relationship between imagery ability, subjective ratings of imagery vividness, neurophysiology, and reality monitoring errors. I predicted that individuals with higher scores on measures of mental imagery would have a greater propensity for reality monitoring errors in both sensory domains. The studys goal was to increase our understanding of the brain areas involved in reality monitoring and how individual differences in imagery ability contribute to misremembering imagined events as having occurred in reality.

description: We consider implications of the diphoton excess recently observed at the LHC on the anomalous magnetic dipole moment of the muon $(g-2)_μ= 2 a_μ$, hypothesizing that the possible 750 GeV resonance is a (pseudo)scalar particle. The (pseudo)scalar-$γ$-$γ$ interaction implied by the diphoton events might generically contribute to $a_μ$ via 2-loop Barr-Zee type diagrams in a broad class of models. If the scalar is an $SU(2)_L$ singlet, the new contribution to $a_μ$ is much smaller than the current anomaly, $Δa_μ\equiv a_μ^{\rm exp}-a_μ^{\rm SM} \approx (30 \pm 10) \times 10^{-10}$, since the scalar can complete the Barr-Zee diagrams only through its mixing with the Standard Model Higgs boson. If the (pseudo)scalar belongs to an $SU(2)_L$ doublet in an extended Higgs sector, then by contrast, $Δa_μ$ can be easily accommodated with the aid of an enhanced Yukawa coupling of the (pseudo)scalar to the muon such as in the Type-II or -X two Higgs doublet model.

Non-Markovian effects in stochastic resonance in a two level system

description: Stochastic resonance is a phenomenon where the response signal to external driving is enhanced by environment noise. In quantum regime, the effect of environment is often intrinsically non-Markovian. Due to the combination of such non-Markovian quantum noise and external driving force, it is difficult to evaluate the correlation function and hence the power spectrum. Nevertheless, a recently developed algorithm, which is called time-evolving matrix product operators (TEMPO), and its extensions provide an efficient and numerically exact approach for this task. Using TEMPO we investigate non-Markovian effects in quantum stochastic resonance in a two level system. The periodic signal and the time-averaged asymptotic correlation function, along with the power spectrum, are calculated. From the power spectrum the signal-to-noise ratio is evaluated. It is shown that both signal strength and signal-to-noise ratio are enhanced by non-Markovian effects, which indicates the importance of non-Markovian effects in quantum stochastic resonance. In addition, we show that the non-Markovian effects can shift the peak position of the background noise power spectrum.

Childrens Physiological Regulation as a Predictor of Adaptive and Maladaptive Guilt
Creators: name: Arden, Cooper
Publisher: name: Georgia State University
Year: 2022

description:
The present study examined associations between both childrens physiological regulation capacity and regulation when discussing disappointing a parent and childrens trait-like adaptive and maladaptive guilt. High-frequency heart rate variability (HF-HRV) was calculated from electrocardiograms of children (N = 104, Age Mean = 9.12, SD = 1.10 years) at rest (regulation capacity) and during the parent-child disappointed discussion. Childrens trait-like maladaptive (child-report) and adaptive (parent-report) guilt were measured with behavioral rating scales. Childrens regulation capacity was unrelated to guilt. Childrens discussion regulation had a significant negative accelerating quadratic relationship with childrens maladaptive guilt wherein for children with below average HF-HRV there was no significant association between HF-HRV and guilt, and for children with above average HF-HRV higher levels of HF-HRV were associated with lower maladaptive guilt. Children with high regulated engagement may have lower levels of maladaptive guilt as they can flexibly engage with others emotions without becoming over-aroused or withdrawing.

description: The prospect of quantum simulating lattice gauge theories opens exciting possibilities for understanding fundamental forms of matter. Here, we show that trapped ions represent a promising platform in this context when simultaneously exploiting internal pseudo-spins and external phonon vibrations. We illustrate our ideas with two complementary proposals for simulating lattice-regularized quantum electrodynamics (QED) in (1+1) space-time dimensions. The first scheme replaces the gauge fields by local vibrations with a high occupation number. By numerical finite-size scaling, we demonstrate that this model recovers Wilson's lattice gauge theory in a controlled way. Its implementation can be scaled up to tens of ions in an array of micro-traps. The second scheme represents the gauge fields by spins 1/2, and thus simulates a quantum link model. As we show, this allows the fermionic matter to be replaced by bosonic degrees of freedom, permitting small-scale implementations in a linear Paul trap. Both schemes work on energy scales significantly larger than typical decoherence rates in experiments, thus enabling the investigation of phenomena such as string breaking, Coleman's quantum phase transition, and false-vacuum decay. The underlying ideas of the proposed analog simulation schemes may also be adapted to other platforms, such as superconducting qubits.

Enablers for PV Development and Benefits of PV

description: 24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 4530-4533
description: Detailed studies and reasonable estimates indicate that in South Asian Countries like India, Pakistan,
Bangladesh, Sri Lanka, Nepal, and Bhutan, the availability of solar radiation averages about 800 watt per square meter
for an average duration of five hours in a day, and the skies remain sunny for about 300 days in a year. Thus, PV
technology for electric power generation projected big potential to these countries. Consequently, the potential for the
PV energy development is huge, not only for homes, hospitals, and other buildings, but also for generating electricity
for providing backup to the conventional grid. Implementation of PV energy not only reduces poverty, but also helps in
enhancing the human development index (HDI) by bringing energy security.
Although PV technologies have been demonstrated successfully; however, few examples are available wherein the
provision of alternative energy has directly resulted in tangible and measurable improvements in the income generation
of the poor communities on any significant scale. Some of the apparent reasons for this are:
i. High initial costs of technology, which the poor cannot afford;
ii. Limited number of locally relevant productive applications suitable for alternative energy;
iii. Poor communities’ limited or no access to supply markets;
iv. Absence of efficient technology service providers and of suitable projects in remote areas that could be bankable
through financial institutions; and
v. Lack of support from the public agencies, because their mandate is energy provision and not income generation for
the poor.
Studies conducted in an Indian tribal village to overcome the above constrains. Details of the studies are presented in
following sections of the paper.
Nonlinear magnetohydrodynamic modeling of current-drive-induced sawtooth-like crashes in the W7-X stellarator

description: Sawtooth-like core electron temperature crashes have been observed in W7-X experiments with electron cyclotron current drive. We present nonlinear single-fluid magnetohydrodynamic simulations of this phenomenon using the newly developed stellarator modeling capability of the M3D-$C^1$ code. The near-axis current drive gives rise to two $ι=1$ resonances in the equilibrium rotational transform profile so that two consecutive $(1,1)$ internal kink modes are seen in the simulations. A small-amplitude crash at the inner resonance occurs first, which may correspond to the sawtooth precursors observed in the experiments. A bigger crash at the outer resonance then flattens the core temperature profile, which shows semi-quantitative agreements with experimental measurements on certain metrics such as the crash amplitude and the inversion radius of the temperature change. These results illustrate a likely mechanism of the current-drive-induced sawtooth-like crashes in W7-X and, to some extent, validate the stellarator modeling capability of M3D-$C^1$.

description: CIGS photovoltaic material has the highest demonstrated thin film material conversion efficiency of close to 20% (1).
Various technologies have been used to grow this material. In the present study, a low cost electrodeposition method
is used to grow the precursor layers followed by the crystallization step to form the CIGS absorber material. Roll to
roll processing tools have been used to fabricate the solar grade CIGS material on flexible metal substrates. The
results show well controlled properties over 1000 feet rolls with large area cells with 12.5% efficiency. Composition
analysis show tight control of Cu/Ga+In and Ga/Ga+In ratios over full rolls demonstrating the suitability of
electrodeposition technique as a low cost CIGS precursor deposition method. Large area solar cells were used to
fabricate flexible panels with aperture efficiency of 11.82%. The panels have total surface area ranging from about
0.87 to 2.6 m2. These panels show excellent stability under damp heat and other standard test conditions and are the
first to receive the UL certification for flexible CIGS panels.

description: We propose an algorithm to determine Maximally Localized Wannier Functions (MLWFs). This algorithm, based on recent theoretical developments, does not require any physical input such as initial guesses for the Wannier functions, unlike popular schemes based on the projection method. We discuss how the projection method can fail on fine grids when the initial guesses are too far from MLWFs. We demonstrate that our algorithm is able to find localized Wannier functions through tests on two-dimensional systems, simplified models of semiconductors, and realistic DFT systems by interfacing with the Wannier90 code. We also test our algorithm on the Haldane and Kane-Mele models to examine how it fails in the presence of topological obstructions.
Identifying Neural Correlates of Positive and Negative Empathy in Middle Childhood
Creators: name: Erin, McDonald
Publisher: name: Georgia State University
Year: 2022

description: 

This study identified if key neural regions associated with empathy in adults showed significant activity while children (N=38) completed a neuroimaging task wherein they won and lost a game for themselves and for peers and witnessed peers subsequent happiness and sadness, which is inferred to elicit empathic happiness and sadness. Regions associated with affective sharing (anterior insula, dorsal anterior cingulate cortex, and amygdala), mentalizing (medial prefrontal cortex and dorsal medial prefrontal cortex), and emotion regulation (anterior cingulate cortex) showed significant activity, relative to a baseline, when children won and lost the game for themselves and for peers. There were not distinctions in degree of activity when sharing others positive compared to negative emotions, nor was there a significant effect of condition on activity in these regions. These results provide support at a neural level that empathic happiness and sadness during middle childhood involves affective sharing, mentalizing, and emotion regulation.

description: Weyl fermions have recently been observed in several time-reversal-invariant semimetals and photonics materials with broken inversion symmetry. These systems are expected to have exotic transport properties such as the chiral anomaly. However, most discovered Weyl materials possess a substantial number of Weyl nodes close to the Fermi level that give rise to complicated transport properties. Here we predict, for the first time, a new family of Weyl systems defined by broken time-reversal symmetry, namely, Co-based magnetic Heusler materials XCo2Z (X = IVB or VB; Z = IVA or IIIA). To search for Weyl fermions in the centrosymmetric magnetic systems, we recall an easy and practical inversion invariant, which has been calculated to be -1, guaranteeing the existence of an odd number of pairs of Weyl fermions. These materials exhibit, when alloyed, only two Weyl nodes at the Fermi level - the minimum number possible in a condensed matter system. The Weyl nodes are protected by the rotational symmetry along the magnetic axis and separated by a large distance (of order 2$π$) in the Brillouin zone. The corresponding Fermi arcs have been calculated as well. This discovery provides a realistic and promising platform for manipulating and studying the magnetic Weyl physics in experiments.

Parental Emotion Socialization and Self-Criticism in Emerging Adulthood: The Roles of Emotion Regulation and Mindfulness
Creators: name: Jena, Michel
Publisher: name: Georgia State University
Year: 2022

description:
Parental emotion socialization (ES) facilitates emotion regulation (ER) in youth, and in turn, impacts risk for psychopathology from childhood through adulthood. While these links are well-documented, self-criticism has received limited attention in relation to ES or ER, despite its transdiagnostic nature. Moreover, no studies have examined how mindfulness may serve to moderate the association between unsupportive ES and ER. Structural equation modeling was used to explore relationships among recalled ES (happiness and sadness) and current ER, self-criticism, and mindfulness in a sample of emerging adults. Final model fit was good across all four models. Supportive ES (happiness and sadness) and unsupportive ES (sadness) predicted self-criticism in the expected directions. ES predicted ER in happiness and sadness models. Specifically, supportive and unsupportive ES predicted expressive suppression, and supportive ES predicted cognitive reappraisal. ES was indirectly associated with self-criticism through ER. Mindfulness did not moderate the link between unsupportive ES and ER.

description: Modeling the non-equilibrium dissipative dynamics of strongly interacting quantized degrees of freedom is a fundamental problem in several branches of physics and chemistry. We implement a quantum state trajectory scheme for solving Lindblad quantum master equations that describe coherent and dissipative processes for a set of strongly-coupled quantized oscillators. The scheme involves a sequence of stochastic quantum jumps with transition probabilities determined the system state and the system-reservoir dynamics. Between consecutive jumps, the wavefunction is propagated in coordinate space using the multi-configuration time-dependent Hartree (MCTDH) method. We compare this hybrid propagation methodology with exact Liouville space solutions for physical systems of interest in cavity quantum electrodynamics, demonstrating accurate results for experimentally relevant observables using a tractable number of quantum trajectories. We show the potential for solving the dissipative dynamics of finite size arrays of strongly interacting quantized oscillators with high excitation densities, a scenario that is challenging for conventional density matrix propagators due to the large dimensionality of the underlying Hilbert space.

Enablers for PV Development and Benefits of PV

description: 24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 4540-4542
description: The Danish municipality of Skive (Skive) has a long track record in energy conservation and use of
renewable energy technologies – from low energy demonstration houses in 1977, 1979 and 1984 to being selected in
2007 as both the Energy Conservation Municipality of the Year, the Energy Optimal Municipality of the Year and
the CO2 Minimal Municipality of the Year followed in 2008 by being nominated “Energy City”.
In the project “PhotoSkive”, 1 MWp of Photovoltaic (PV) generating capacity will be installed on a broad selection
of municipal buildings from nurseries to schools, hospitals and technical/administrative facilities. For each group of
buildings an awareness and information campaign will be developed and implemented, and results will be monitored.
The total annual net electricity production is estimated to 850.000 kWh.
The PV installations will be implemented as a public-private-partnership (PPP), where the energy utility EnergiMidt
and the Municipality of Skive will develop PPP models which will install approx. 1 MWp of PV as BIPV, and which
can be used as models for other municipalities.
Do Monkeys Save the Best for Last? Examining Sequence Order Preference in Capuchin Monkeys
Creators: name: Jhonatan, Saldana
Publisher: name: Georgia State University
Year: 2022

description:
Primate decision-making is often underlined by cognitive biases and how sequences are evaluated is no different. Human research shows the most salient parts of sequences are the peak and end affect experienced within them along with a preference for sequences with increasing value. However, inconsistent results from non-human primate studies deny the ability to determine if these biases are a primate-wide cognitive shorthand to quickly evaluate experiences, or if these primarily impact humans. This experiment builds on previous works and tests if tufted capuchin monkeys experience an end bias using a dichotomous manual task which allows them to choose between receiving a high reward sooner or later. Overall, capuchin monkeys preferred a higher reward at the start of a sequence, this effect only was strengthened when accounting for delay discounting. Rank and exposure to sequences were most often the best predictors for sequence preference, while sex never impacted choice.
