description: Zosterops intermedia periplecta Hartert Zosterops intermedia periplecta Hartert, 1920: 434 (Lombok, 1500 feet). Now Zosterops chloris maxi Finsch, 1907. See Mees, 1961a: 43–48, White and Bruce, 1986: 414, and van Balen, 2008: 453–454. LECTOTYPE: AMNH 700349, adult male, collected on Lombok Island, 1500 ft, 08.45S, 116.30E (White and Bruce, 1986: 490), Lesser Sunda Islands, Indonesia, in May 1896, by Alfred Everett. From the Rothschild Collection. COMMENTS: Hartert (1920: 434) described this subspecies within his list of types in the Rothschild Collection. The Rothschild type label is tied on the above specimen, and it is without doubt the intended type; however, there are two specimens bearing the same data. By listing AMNH 700349 as the type, Mees (1961a: 46) designated it the lectotype. Hartert (1920: 434) said that he had three specimens of periplecta collected by Everett and five by Doherty, all from Lombok. The seven paralectotypes are: AMNH 700350, male, May 1896, Everett; AMNH 700351, AMNH 700352, males, AMNH 700353– 700355, females, June 1896, Doherty; AMNH 700356, female, June 1896, native collectors for Everett. AMNH 295136 is also a male collected on Lombok in May 1896 by Everett, but this specimen has no type standing; it was purchased from W.F.H. Rosenberg, a dealer, by Leonard C. Sanford for AMNH and was not part of Hartert’s type series.

description: We consider a mechanical resonator made of diamond, which contains a nitrogen-vacancy center (NV center) locating at the end of the oscillator. A second order magnetic gradient is applied and inducing coupling between mechanical modes and the NV center. By applying proper external magnetic field, the energy difference between NV center electron spin levels can be tuned to match the energy difference between two mechanical modes $a$ and $b$. A laser is used for continuously initializing the NV center electron spin. The mode $a$ with lower frequency is driven by a thermal bath. We find that the temperature of the mode $b$ is significantly cooled when the heating bath temperature is increased. We discuss the conditions that quantum regime cooling requires, and confirm the results by numerical simulation. Finally we give the intuitive physical explanation on this unusual effect.

description: Stabilised electric performance data are necessary to compare different types of modules in the
emerging thin film PV market and as basic information for energy yield calculations. The problems with accurate
power measurements of thin film modules are well known. The module test standard IEC 61646 ed. 2 tries to take
these into account by demanding light soaking and repeated STC measurements.
Various types of CdTe, CIS and a-Si modules were installed on a outdoor test facility in Freiburg, Germany,
facing south in 45° inclination. IV-Curves of all these modules are measured every ten minutes. Between the
measurements of IV-curves the modules are held in MPP conditions by electronic loads. Isc, Voc, efficiency and
filling factor are determined automatically.
Measured irradiation, module temperature and air mass are used for analysis and comparison of the IV-curves.
The influence of the respective air mass was higher than expected and therefore regarded more intensely. Measured
data were corrected to 1000 W/m² irradiation and to 25°C module temperature according to standard IEC 60891 in
order to make them comparable.
Different procedures of filtering and correction have been compared. The results show that the best results are
achieved when the data are selected in a small range of air mass and module temperature and corrected to the same
irradiation. An additional correction to air mass was carried out.
Some modules of the same types like the outdoor exposed modules were stored without irradiation for some
years. Afterwards, they were exposed at the test site side by side with the other modules. Comparison of the module
data of the same type allows the investigation of the stabilisation behaviour of the modules directly.

description: In supersymmetric models where the superpotential mu term is generated with mu<< m_{soft} (e.g. from radiative Peccei-Quinn symmetry breaking or compactified string models with sequestration and stabilized moduli), and where the string landscape 1. favors soft supersymmetry (SUSY) breaking terms as large as possible and 2. where the anthropic condition that electroweak symmetry is properly broken with a weak scale m_{W,Z,h}~100 GeV ({\it i.e.} not too weak of weak interactions), then these combined landscape/anthropic requirements act as an attractor pulling the soft SUSY breaking terms towards values required by models with radiatively-driven naturalness: near the line of criticality where electroweak symmetry is barely broken and the Higgs mass is ~125 GeV. The pull on the soft terms serves to ameliorate the SUSY flavor and CP problems. The resulting sparticle mass spectrum may barely be accessible at high-luminosity LHC while the required light higgsinos should be visible at a linear e^+e^- collider with \sqrt{s}>2m(higgsino).

description: Silicon based hetero-junction solar cells have the potential of combining advantages of both crystal
silicon and thin film solar cells with the best example HIT solar cells from Sanyo. The chalcopyrite semiconductors,
with the compounds composition I(B)-III(A)-VI(A)2, have been reported as the highest light absorption
semiconductor and a similar lattice to silicon with the mismatch -0.7% ~0.8%. This document studied the
feasibility of silicon wafer based chalcopyrite semiconductor hetero-junction solar cell, and fabricated NPP+ and
PNN+ hetero-junction solar cell structures based on p- or n- type wafers. By the means of numerical analysis with
AMPS-1D simulation on PNN+ structure, the influence of front contact barrier, chalcopyrite emitter band-gap,
acceptor density, carrier mobility and its thickness, wafer thickness, as well as back surface field doping level, were
studied. In order to obtain high efficiency, the minimum p-chalcopyrite band-gap and thickness is 1.3eV and 2μm,
respectively. The best chalcopyrite acceptor density is 7×1016/cm3, and the carrier mobility should be as large as
possible. As for wafer, its minimum thickness is 150μm, with an optimized back surface doping ~1019/cm3. The most
important impact to cell performance is a high work function TCO layer to obtain high front contact barrier. If the
barrier reaches 1.4eV, 26.6% efficient PNN+ Si-chalcopyrite hetero-junction solar cell is predicted.

description: Statistical properties of the one-dimensional spring-block (Burridge-Knopoff) model of earthquakes obeying the rate and state dependent friction law are studied by extensive computer simulations. The quantities computed include the magnitude distribution, the rupture-length distribution, the mainshock recurrence-time distribution, the seismic time correlations before and after the mainshock, the mean slip amount, and the mean stress drop at the mainshock, etc. Events of the model can be classified into two distinct categories. One tends to be unilateral with its epicenter located at the rim of the rupture zone of the preceding event, while the other tends to be bilateral with enhanced "characteristic" features resembling the so-called "asperity". For both types events, the distribution of the rupture length $L_r$ exhibits an exponential behavior at larger sizes, $\approx \exp[-L_r/L_0]$ with a characteristic "seismic correlation length" $L_0$. The mean slip as well as the mean stress drop tends to be rupture-length independent for larger events. The continuum limit of the model is examined, where the model is found to exhibit pronounced characteristic features. In the continuum limit, the characteristic rupture length $L_0$ is estimated to be $\sim $100 [km]. This means that, even in a hypothetical homogenous infinite fault, events cannot be indefinitely large in the exponential sense, the upper limit being of order $\sim 10^3$ kilometers. Implications to real seismicity are discussed.

description: In this paper, 4 types of photovoltaic modules were selected to compare the electrical characteristics by
changing light pulse duration time and voltage scan direction. Light pulse duration time was varied from 10msec to
800msec. For high efficiency solar cell and HIT solar cell module need 50~60msec to have stable Pmax. But for
normal crystalline solar cell and amorphous silicon thin film module, maximum power can be measured even in 10

description: The spectral function of the $Λ$ hyperon in finite nuclei is calculated from the corresponding $Λ$ self-energy, which is constructed within a perturbative many-body approach using some of the hyperon-nucleon interactions of the Jülich and Nijmegen groups. Binding energies, wave functions and disoccupation numbers of different single-particle states are obtained for various hypernuclei from $^5_Λ$He to $^{209}_{\,\,\,\,\,Λ}$Pb. The agreement between the calculated binding energies and experimental data is qualitatively good. The small spin-orbit splitting of the $p-, d-, f-$ and $g-$wave states is confirmed. The discrete and the continuum contributions of the single-$Λ$ spectral function are computed. Their appearance is qualitatively similar to that of the nucleons. The $Z$-factor, that measures the importance of correlations, is also calculated. Our results show that its value is relatively large, indicating that the $Λ$ hyperon is less correlated than nucleons. This is in agreement with the results obtained by other authors for the correlations of the $Λ$ in infinite nuclear matter. The disoccupation numbers are obtained by integrating the spectral function over the energy. Our results show that the discrete contribution to the disoccupation number decreases when increasing the momentum of the $Λ$. This indicates that, in the production reactions of hypernuclei, the $Λ$ hyperon is mostly formed in a quasi-free state.

description: Background: The COVID-19 pandemic and accompanying restrictions are associated with substantial psychological distress. However, it is unclear how this increased strain translates into help-seeking behavior. Here, we aim to characterize those individuals who seek help for COVID-19 related psychological distress, and examine which factors are associated with their levels of distress in order to better characterize vulnerable groups. Methods: We report data from 1269 help-seeking participants subscribing to a stepped-care program targeted at mental health problems due to the COVID-19 pandemic. Sample characteristics were compared to population data, and linear regression analyses were used to examine which risk factors and stressors were associated with current symptom levels. Results: Seeking for help for COVID-19 related psychological distress was characterized by female gender, younger age, and better education compared to the general population. The majority reported mental health problems already before the pandemic. 74.5% of this help-seeking sample also exceeded clinical thresholds for depression, anxiety, or somatization. Higher individual symptom levels were associated with higher overall levels of pandemic stress, younger age, and pre-existing mental health problems, but were buffered by functional emotion regulation strategies. Conclusions: Results suggest a considerable increase in demand for mental-healthcare in the pandemic aftermath. Comparisons with the general population indicate diverging patterns in help-seeking behavior: while some individuals seek help themselves, others should be addressed directly. Individuals that are young, have pre-existing mental health problems and experience a high level of pandemic stress are particularly at-risk for considerable symptom load. Mental-healthcare providers should use these results to prepare for the significant increase in demand during the broader aftermath of the COVID-19 pandemic as well as allocate limited resources more effectively.
INVESTIGATION OF ROLLING ELEMENT BEARING LUBRICATION AND FRICTION
Creators: name: Peterson, Wyatt L
Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Tribology

description: Lubrication and friction of modern rolling element bearings were investigated to develop a physics-based bearing friction model. A test rig was designed and developed to measure the frictional torque of radially loaded rolling element bearings with oil bath lubrication. Deep groove ball bearings and radial needle roller bearings were studied at various loads, speeds and lubrication conditions. Experimental results indicate that bearing friction models currently used in industry can be inaccurate, especially when predicting bearing fluid drag losses. A separate test rig was designed and developed to investigate the lubrication and friction of rolling element bearing cage pockets, as new cage pocket designs could improve bearing efficiency. Cage pocket oil starvation was observed for certain operating conditions, and the starvation was found to correlate strongly with cage pocket friction. In order to better understand friction and lubrication characteristics of bearings, computational fluid dynamics (CFD) models were developed to compare with the experimental results. Fluid motion inside the rolling element bearings was investigated using CFD to determine fluid drag torque of bearing components. Fluid drag torque obtained from CFD and experimental measurements are in good agreement. Results from the CFD models also included pressure distributions over bearing surfaces and fluid velocity near rolling elements, but were limited to global length scales. At the micro-scale, rolling element bearing lubrication and friction is dictated by elastohydrodynamic lubrication (EHL). The radial needle roller bearings and deep groove ball bearings used in this investigation are characterized by line and elliptical contacts, respectively. EHL modeling was therefore developed for line contacts with a strongly coupled fluid solid interaction (FSI) solver. Solid bodies were modeled with finite element (FE) software to incorporate inhomogeneities such as inclusions and surface features which affect EHL pressure, film thickness and friction. Results were used to investigate lubricant film thickness at lubricated line contacts under various operating conditions. This work was further extended to model EHL circular contacts with an FSI approach, combining CFD and FE software. The newly developed FSI EHL model provided critical insights regarding fluid behavior in and around EHL point contacts and fluid properties within the lubricant film. Given the modeling results at the micro and macro scale within the rolling element bearings, a better understanding of bearing friction and lubrication is developed, and supported by experimental data.
Abusive comments in student evaluations of courses and teaching: the attacks women and marginalised academics endure

description: This paper examines the volume and type of anonymous comments academics receive in student evaluations of courses and teaching (SETs) at the 16,000 higher education institutions that collect this data at the end of each teaching period. Existing research has increasingly pointed to the negative issues of student surveys, but very little research has focused on the volume, type, and impact of anonymous student comments on academics. This paper analyses the survey results of 674 academics to inform higher education leaders and the sector more widely of the amount and type of abusive comments academics are receiving. The work also demonstrates that the highest volume, most derogatory, and most threatening abuse is directed towards women academics and those academics from marginalised groups. The paper finds that previous estimates of the rate and severity of abusive comments that academics receive, and the impact to academics’ wellbeing, mental health, and career progression, have underestimated what is taking place. The paper argues that many universities are failing to protect their staff from this abuse, and the prejudice nature of SET results, which will continue to have a negative impact on the career progression of marginalised academics - a major flaw in a sector that prides itself on diversity and inclusion.
Non-Gaussian operations on bosonic modes of light: Photon-added Gaussian channels

description: We present a framework for studying bosonic non-Gaussian channels of continuous-variable systems. Our emphasis is on a class of channels that we call photon-added Gaussian channels, which are experimentally viable with current quantum-optical technologies. A strong motivation for considering these channels is the fact that it is compulsory to go beyond the Gaussian domain for numerous tasks in continuous-variable quantum information processing such as entanglement distillation from Gaussian states and universal quantum computation. The single-mode photon-added channels we consider are obtained by using two-mode beam splitters and squeezing operators with photon addition applied to the ancilla ports giving rise to families of non-Gaussian channels. For each such channel, we derive its operator-sum representation, indispensable in the present context. We observe that these channels are Fock preserving (coherence nongenerating). We then report two examples of activation using our scheme of photon addition, that of quantum-optical nonclassicality at outputs of channels that would otherwise output only classical states and of both the quantum and private communication capacities, hinting at far-reaching applications for quantum-optical communication. Further, we see that noisy Gaussian channels can be expressed as a convex mixture of these non-Gaussian channels. We also present other physical and information-theoretic properties of these channels.

description: Silicon nanocrystals are promising objects for quantum and photovoltaic devices. However, there are
open questions concerning the influence of the embedding amorphous SiO2 matrix and the nanocrystal-matrix
interface. In contrast to the planar Si/SiO2 interfaces with defined crystallographic orientation in layered
heterostructures, the nanocrystals are surrounded by almost spherical interfaces with various facets. Here we study
the interfacial electronic and bonding properties of Si nanocrystals embedded in SiO2 by large-scale first-principles
calculations. They are based on the density functional theory. In our simulations Si nanocrystals with nominal
diameters up to 1.6 nm, i.e. systems with more than 1000 atoms, are treated. The atomic geometries are optimized
within full quantum-mechanical calculations. The fundamental gap of the nanocrystal depends significantly on the
matrix. We compute the spatial variation of the electronic structure. The local band edge profiles exhibit different
band gaps in the Si nanocrystals and in the matrix region. Significant differences are found comparing embedded Si
nanocrystals and planar Si/SiO2 interfaces.

description: It has been reported in experiments that capping layers which enhance the perpendicular magnetic anisotropy (PMA) of magnetic tunnel junctions (MTJs) induce great impact on the tunnel magnetoresistance (TMR). To explore the essential influence caused by capping layers, we carry out ab initio calculations on TMR in the X(001)|CoFe(001)|MgO(001)|CoFe(001)|X(001) MTJ, where X represents the capping layer material which can be tungsten, tantalum or hafnium. We report TMR in different MTJs and demonstrate that tungsten is an ideal candidate for a giant TMR ratio. The transmission spectrum in Brillouin zone is presented. It can be seen that in the parallel condition of MTJ, sharp transmission peaks appear in the minority-spin channel. This phenomenon is attributed to the resonant tunnel transmission effect and we explained it by the layer-resolved density of states (DOS). In order to explore transport properties in MTJs, the density of scattering states (DOSS) was studied from the point of band symmetry. It has been found that CoFe|tungsten interface blocks scattering states transmission in the anti-parallel condition. This work reports TMR and transport properties in MTJs with different capping layers, and proves that tungsten is a proper capping layer material, which would benefit the design and optimization of MTJs.

description: Amorphous silicon based alloys, as for example Silicon Carbide (SiC) or Silicon Nitride (SiN), has
started to play important role in the semiconductor industry, also in photovoltaics. Amorphous silicon carbide (a –
SiC) films were prepared by PECVD technology in capacitive parallel plate plasma reactor. A gas mixture of SiH4
and CH4 was directly introduced into the reaction chamber through a shower head. Properties of thus produced films
were studied by electrical and dielectrical measurement. Forward (FW) and reverse (RV) current-voltage (I-V)
characteristics (Al – SiC/Si–Al structures) are shown in this paper. Parameters as factor ideality and saturation current
were measured and calculated. To more complex characterization of prepared structures data from capacitance
voltage (C-V), conductance voltages (G-V) are presented. The bonds at surface of amorphous layers were identified
by FTIR.

description: The ability to contact p-type (boron doped) emitters effectively is becoming increasingly important for
the realisation of industrially feasible high-efficiency solar cell concepts (i.e. phosphorus diffused Si substrates,
heterojunction devices etc). To date p-type emitter contacts have utilised aluminium particulate as the dopant source
to improve the conductor’s contact characteristics, however aluminium doping can itself introduce new design
challenges, including the degradation of solderability, adhesion and grid resistance of the conductor during or after
firing. This paper demonstrates novel thick-film metallizations designed to etch through SiNx: H/SiO2 passivation
stacks during firing whilst providing good ohmic contact to boron (BBr3) diffused emitters. Corescan data and
normalised transfer length measurement (TLM) data is reported together with good line resistivity and solder
adhesion strengths of >2N. Pastes using a range of doping additives are discussed, and contrasts drawn between ptype
and n-type contact mechanism. An initial investigation of the p-type conductor-semiconductor interface is
undertaken using scanning electron microscopy, and the results discussed.

description: In conventional metals, electronic transport in a magnetic field is characterized by the motion of electrons along orbits on the Fermi surface, which usually causes an increase in the resistivity through averaging over velocities. Here we show that large deviations from this behavior can arise in density-wave systems close to their ordering temperature. Specifically, enhanced scattering off collective fluctuations can lead to a change of direction of the orbital motion on reconstructed pockets. In weak magnetic fields, this leads to linear magnetoconductivity, the sign of which depends on the electric-field direction. At a critical magnetic field, the conductivity crosses zero for certain directions, signifying a thermodynamic instability of the density-wave state.

description: Electroluminescence (EL) and photoluminescence (PL) cartographies of solar cells are powerful
characterization methods allowing to access material properties, such as transport mechanisms and open-circuit
voltage (VOC). We present here results obtained from a hyperspectral imager coupled to a microscope. This
original characterization tool allows fast acquisition of the luminescence signal on a large area with an absolute
measurement possibility. We recorded PL spatial variations of CuInS2 samples, and compare the results to data
acquired from a confocal microscope. EL absolute signal was acquired from GaAs samples, allowing to directly
determine external quantum efficiency (EQE) using reciprocity relations. This operation needs a careful analysis
of resistive loss. We therefore show that the hyperspectral imager system is a powerful tool to use the reciprocity
relations.

Koszul duality and homotopy theory of curved Lie algebras

description: This paper introduces the category of marked curved Lie algebras with curved morphisms, equipping it with a closed model category structure. This model structure is---when working over an algebraically closed field of characteristic zero---Quillen equivalent to a model category of pseudo-compact unital commutative differential graded algebras; this extends known results regarding the Koszul duality of unital commutative differential graded algebras and differential graded Lie algebras. As an application of the theory developed within this paper, algebraic deformation theory is extended to functors on pseudo-compact, not necessarily local, commutative differential graded algebras.

description: The voltage of the distribution line in the district where the PV systems are clustered will be raised by reversal power flow from the PVs. Then active power control of the PV systems depresses the output. As a solution to this problem, we investigate the PV system with the storage battery in this paper. It is necessary for advantages and disadvantages of the battery operating methods to be clarified so that the person who uses the battery can properly design its operation depending on his purpose or the situation. In this paper, we investigate several characteristic battery operations by computational simulation and perform the multidirectional evaluation on the operations by means of seven kinds of indices.

description: Background: Non-invasive biochemical markers are needed to support the diagnosis of ulcerative colitis (UC), an incurable disease of unknown pathology. Midkine is an angiogenic cytokine, chemotactic towards neutrophils and macrophages, and a T-regulatory cell suppressor. Methods: Serum midkine was measured immunoenzymatically in 93 UC patients and 108 healthy subjects, and evaluated with respect to disease status, endoscopic, inflammatory and angiogenic activity. The diagnostic value of midkine was compared to C-reactive protein (CRP) using receiver operating characteristics (ROC) analysis. Results: Midkine was higher (p<0.0001) in inactive (199 ng/L) and active UC (351 ng/L) compared with controls (93 ng/L), and reflected disease activity (r=0.427, p<0.001). Midkine was correlated with CRP, erythrocyte sedimentation rate (ESR), leukocytes, platelets, interleukin-6, paraoxonase-1, albumin, transferrin, iron, hemoglobin, and hematocrit. Midkine correlated with angiogenic factors: vascular endothelial growth factor-A and platelet-derived growth factor-BB. As a marker of UC, midkine showed a diagnostic accuracy of 85%, sensitivity of 72%, specificity of 82%, whereas CRP showed 83%, 65% and 91%, respectively. As a marker of active UC, midkine showed a diagnostic accuracy of 87%, sensitivity of 84%, specificity of 75%, whereas CRP showed 75%, 63% and 83%, respectively. Combined assessment of midkine and CRP improved sensitivity but substantially decreased specificity. Conclusions: UC is associated with increased circulating midkine, which corresponds with clinical, endoscopic, inflammatory and angiogenic activity, and anemia. Performance of midkine as a marker of UC or active UC was comparable to that of CRP. Clin Chem Lab Med 2009;47:1085–90.

description: This work reports on the possibility of regeneration of light degraded efficiency of triple junction
amorphous silicon solar modules in an outdoor environment. Regeneration occurs by annealing at modules working
conditions. Modules were annealed by heating to the temperature 30 °C higher than their functional worksite
temperature. Small flat heaters were attached underneath the modules. Depending on conditions recovery of up to 85
% of degraded efficiency was possible. Regenerated modules were thermally insulated. The process of annealing
required small amount of electric energy when combined with solar radiation. During warm sunny conditions
regeneration occurred under Sun exposure alone without external heating, however longer solar radiation exposure
times were required. The proposed method of regeneration could be applied successfully in warm Mediterranean
climates or during summer in moderate climates.

description: Let $A=\frac{\mathbb{F}[x]}{\langle f(x)\rangle }$, where $f(x)$ is a monic polynomial over a finite field $\mathbb{F}$. In this paper, we study the relation between $A$-codes and their duals. In particular, we state a counterexample and a correction to a theorem of Berger and El Amrani (Codes over finite quotients of polynomial rings, \emph{Finite Fields Appl.} \textbf{25} (2014), 165--181) and present an efficient algorithm to find a system of generators for the dual of a given $A$-code. Also we characterize self-dual $A$-codes of length 2 and investigate when the $\mathbb{F}$-dual of $A$-codes are $A$-codes.

Extending the scope of holographic mutual information and chaotic behavior

description: We extend the use of holography to investigate the scrambling properties of various physical systems. Specifically, we consider: (i) non-conformal backgrounds of black $Dp$ branes, (ii) asymptotically Lifshitz black holes, and (iii) black $AdS$ solutions of Gauss-Bonnet gravity. We use the disruption of the entanglement entropy as a probe of the chaotic features of such systems. Our analysis shows that these theories share the same type of behavior as conformal theories as they undergo chaos; however, in the case of Gauss-Bonnet gravity, we find a stark difference in the evolution of the mutual information for negative Gauss-Bonnet coupling. This may signal an inconsistency of the latter.

description: We have improved the emitter formation process by manipulating the phosphorus doping profile
without increasing the total process time or adding any extra steps, but by just implementing a simple steam
generator into the POCl3 diffusion furnace. An average efficiency gain of 0.3% absolute was achieved with
multicrystalline silicon solar cells. In this study, we statistically clarify which direction the doping profile should be
manipulated. Merely characterizing the emitter by “high sheet resistance” or “shallow emitter” is revealed to be no
longer indicative for high efficiency. We also demonstrate the sophistication of the doping profile manipulation with
numerical analysis.
