Working Papers of the Cornell Phonetics Lab No. 6, Oct 1991 - The Tonal Phonology of Llogoori: A Study of Llogoori Verbs

description: This issue of the Working Papers consists of a single study: Elizabeth Leung's 1986 M.A. thesis, a phonological study of the
 Llogoori language of Kenya. The reader may ask why this work is being made available to a wider public after a delay of five years. Elizabeth Leung's study constitutes the first extensive linguistic description of a language whose basic structural features are still unfamiliar to Bantuists and other linguists. Thus, any information that can be made available on this language is of importance to Bantu studies. Beyond this, however, Leung's study goes well beyond the requirements of rudimentary description, consisting not only of a clear and well-exemplified presentation of major phonological (and morphological) features of the language, but of a carefully worked out and internally consistent analysis, one of the first comprehensive. treatments of a Bantu language within the framework of an early 1980's model of nonlinear phonology. In addition to its descriptive interest, this work provides new evidence for the nature of tonal representation in Bantu languages.
 It is known that the languages of this group vary along a scale from pure tonal systems with an underlying contrast between H (high) tone, L (low) tone, and zero tone, to "tonal accent" systems contrasting H tone with its absence. Llogoori appears to lie on a mid-point on this scale.

description: The introduction of new solar cell structures as e.g. PERC or HIP-MWT into industrial fabrication increases the cell
production complexity considerably to the still widely produced H-pattern Al-BSF solar cell. But due to the higher
efficiency of the new cell structures, their increased production costs can pay off within the following module
production or on system level, as area-proportional costs are used more efficiently. We present a cost calculation
model for the economic comparison of different silicon solar cell production technologies with respect to the impact
of a cell efficiency improvement on the cost of ownership of each subsequent stage of the PV value chain. Following
the presentation of our approach, we show an exemplary cost-of-ownership calculation, demonstrating that the
industrial production of a PERC or a HIP-MWT cell structure can be economically feasible. The roughly 30 % higher
cell production costs are already amortized on module level, on system level the advanced cell structures show a cost
advantage compared to the Al-BSF cell structure.

description: Background: Trace elements are essential substances for the proper physiological and biochemical functioning of the organism. Hemodialysis patients are potentially at risk of deficiency or excess of these elements. The application of inductively coupled plasma mass spectrometry (ICP-MS) allows the simultaneous quantification of very small amounts of multiple trace elements. The aim was to measure the serum concentration of copper (Cu), zinc (Zn), selenium (Se), and nickel (Ni), and the whole blood concentration of arsenic (As), lead (Pb), and manganese (Mn), in patients undergoing hemodialysis as well as in controls. Methods: The study was carried out in 57 hemodialysis patients compared with 57 controls with normal renal function. Serum and whole blood samples from the dialysis group were collected before and after hemodialysis sessions and Cu, Zn, Se, Ni, As, Pb and Mn levels were determined using ICP-MS. Results: Hemodialysis patients showed significantly lower blood levels of Cu, Zn and Se than controls (p p p p Conclusion: Hemodialysis patients are at increased risk of trace elements deficiency (especially for Zn and Se) or excess (Ni) in respect to healthy subjects. Monitoring of blood levels and supplementation of some trace elements may be indicated in patients undergoing hemodialysis.

description: Photoluminescence images of the side faces of a multi-crystalline silicon brick yield valuable information
of the electric quality of the material. However, the signal originates from only the first millimeters of the surface
and thus contains no bulk information. If consecutive PL-images of wafers sliced from a whole brick are taken
and combined, a tomographic reconstruction of the brick is possible. This approach opens a new insight into the silicon
crystallization process and its influence on solar cell parameters. By means of image processing crystal growth,
impurities, grain boundaries and defect clusters can be reconstructed three dimensionally helping to identify the
origin of certain defects and to further optimize the crystallization process.

description: The ability of thick film, screen-printable silver pastes to contact crystalline solar cells with
homogeneous, low surface dopant phosphorus concentration (surface [P] < 5E20 atoms/cm³) emitters has been elusive
for current industry-standard commercial pastes due to poor contact resistivity (c) and damage to the emitter layer
(i.e., high J02 and low shunt resistivity). This paper discusses a unique silver conductor metallization that can contact
emitters with diffusion profiles having low surface phosphorus concentration. Contact to the emitter surface is
established via conductor line–silicon interface films that are highly uniform and have nanometer-scale thicknesses
where electron conduction occurs via tunneling mechanisms through the interfacial films. The ultra-thin, uniform
interfacial films result in improved conductor line contact resistivity and reduced emitter/junction damage enabling a
mean efficiency of 18.9% on industrially processed mono-c Si solar cells with low surface phosphorus concentration
diffusion profiles (surface [P] = 2.4E20 atoms/cm³) and low J0e (130 fA/cm2). This is a 0.4% to 0.5% absolute
efficiency gain compared to heavily phosphorous doped emitters (surface [P] = 8.2E20 atoms/cm3) with industry
standard screen-printable silver pastes.

description: The major challenge of multiple quantum wells (MQWs) solar cells is to sufficiently extract photoexcited
carriers to the external circuit at the operation voltage through MQWs regions. The present study reports the
effectiveness of compensation doping of the i-region, which includes MQWs, for more efficient transport of both
electrons and holes. P-type unintentional doping exists in GaAs by inevitable carbon incorporation during MOVPE,
causing undesired bending of the band-lineup in the i-region. By cancelling this out with n-type dopants, sulfur, we
have achieved much high carrier collection efficiency of >90% at the operation bias voltage regardless of the
excitation wavelength, compared to <50% without compensation doping treatment. As a result, the cell performance
was greatly improved, especially showing an enhanced FF from 0.54 to 0.77, and the degradation-free QE within
GaAs absorption wavelength range. The bias dependent PL analysis showed that PL intensity increased as the CCE
decreases at a large forward bias, and that the radiative recombination loss was significantly suppressed by
compensation doping. Furthermore, time-resolved PL study indicated much faster speed of carrier escape from the
wells, showing a quicker PL decay time of 7 ns at 0.6 V, compared to 18-51 ns without compensation doping.

description: At imec a small area (4 cm2) baseline process for interdigitated back contact (IBC) silicon solar cells
based on n-type float-zone (FZ) and Czochralski (CZ) wafers has been developed. We obtained best cell conversion
efficiencies of 23.3 % and 22.8 % on n-type 100 mm FZ and 125 mm CZ silicon substrates, respectively. Performing
an identical process on one particular set of 156 mm n-type CZ substrates resulted in a large distribution of cell
efficiencies within one wafer, likely to be related to the formation of oxygen precipitates during the high temperature
process steps leading to degradation of the bulk lifetime. Further investigation will be done to make the process more
tolerant to be applied on a variety of CZ substrates with different oxygen concentration. This IBC baseline serves as a
test vehicle to innovate the integration sequence and is a starting point to upscale the IBC process to large-area IBC
cells and explore new finger grid designs on 156 mm CZ silicon wafers. The final goal is to realize a simplified and
cost effective IBC process flow reaching cell efficiencies above 22%.

description: This thesis navigates the evolving landscape of truck platooning, a transformative technology reshaping the transportation sector. Comprising three interconnected chapters, the research delves into critical aspects of platooning dynamics, stability, and the implications of introducing matching platforms. The first chapter explores the stability of two-truck platooning, considering time constraints and the flexibility of truck drivers in deviating from centrally designed plans. Utilizing novel mathematical models, the study expands on individual drivers' knowledge and preferences, shedding light on the dynamics of truck platooning in network settings. The second chapter extends the investigation to multi-company platoon formations, emphasizing not only fuel savings but also stability, truthfulness, and efficiency in information sharing. A stable, efficient, and fair scheme and truthful mechanisms are introduced to address the challenges of forming stable and efficient platoons among trucks from different companies. The third chapter adopts a system dynamic approach, qualitatively and quantitatively examining the industry's adoption of platooning technology. It introduces a matching platform and investigates its impact on technology diffusion, revealing insights that indicate a significant acceleration in technology adoption. Collectively, these contributions provide a comprehensive framework for understanding, implementing, and optimizing truck platooning in the evolving landscape of the freight industry.

description: We are pursuing an experiment to measure the electric dipole moment of the electron using the molecule PbO. This measurement requires the ability to prepare quantum states with orientation of the molecular axis and, simultaneously, alignment of the electron spin perpendicular to this axis. It also requires efficient detection of the evolution of the spin alignment direction within such a state. We describe a series of experiments that have achieved these goals, and the features and limitations of the techniques. We also discuss possible new approaches for improved efficiency in this and similar systems.

description: Multiwavelength studies of the seven identified X-ray dim isolated neutron stars (XDINSs) offer a unique opportunity to investigate their surface thermal and magnetic structure and the matter-radiation interaction in presence of strong gravitational and magnetic fields. As a part of an ongoing campaign aimed at a complete identification and spectral characterization of XDINSs in the optical band, we performed deep imaging with the ESO Very Large Telescope (VLT) of the field of the XDINS RBS1774 (1RXS J214303.7 +065419). The recently upgraded FORS1 instrument mounted on the VLT provided the very first detection of a candidate optical counterpart in the B band. The identification is based on a very good positional coincidence with the X-ray source (chance probability ~2E-3). The source has B=27.4 +/- 0.2 (1 sigma confidence level), and the optical flux exceeds the extrapolation of the X-ray blackbody at optical wavelengths by a factor ~35 (+/- 20 at 3sigma confidence level). This is barely compatible with thermal emission from the neutron star surface, unless the source distance is d~200-300 pc, and the star is an almost aligned rotator or its spin axis is nearly aligned with the line of sight. At the same time, such a large optical excess appears difficult to reconcile with rotation-powered magnetospheric emission, unless the source has an extremely large optical emission efficiency. The implications and possible similarities with the optical spectra of other isolated NSs are discussed.

description: To optimize the last high temperature step of a standard solar cell fabrication process (the contact cofiring
step), the aluminium gettering is incorporated in the Impurity-to-Efficiency simulation tool, so that it models
the phosphorus and aluminium co-gettering effect on iron impurities. The impact of iron on the cell efficiency will
depend on the balance between precipitate dissolution and gettering. Gettering efficiency is similar in a wide range of
peak temperatures (600-850 ºC), so that this peak temperature can be optimized favoring other parameters (e.g. ohmic
contact). An industrial co-firing step can enhance the co-gettering effect by adding a temperature plateau after the
peak of temperature. For highly contaminated materials, a short plateau (< 2 min) at low temperature (600 ºC) is
shown to reduce the dissolved iron.
Exploring mutual information between IRIS spectral lines. I. Correlations between spectral lines during solar flares and within the quiet Sun

description: Spectral lines allow us to probe the thermodynamics of the solar atmosphere, but the shape of a single spectral line may be similar for different thermodynamic solutions. Multiline analyses are therefore crucial, but computationally cumbersome. We investigate correlations between several chromospheric and transition region lines to restrain the thermodynamic solutions of the solar atmosphere during flares. We used machine-learning methods to capture the statistical dependencies between 6 spectral lines sourced from 21 large solar flares observed by NASA's Interface Region Imaging Spectrograph (IRIS). The techniques are based on an information-theoretic quantity called mutual information (MI), which captures both linear and nonlinear correlations between spectral lines. The MI is estimated using both a categorical and numeric method, and performed separately for a collection of quiet Sun and flaring observations. Both approaches return consistent results, indicating weak correlations between spectral lines under quiet Sun conditions, and substantially enhanced correlations under flaring conditions, with some line-pairs such as Mg II and C II having a normalized MI score as high as 0.5. We find that certain spectral lines couple more readily than others, indicating a coherence in the solar atmosphere over many scale heights during flares, and that all line-pairs are correlated to the GOES derivative, indicating a positive relationship between correlation strength and energy input. Our methods provide a highly stable and flexible framework for quantifying dependencies between the physical quantities of the solar atmosphere, allowing us to obtain a three-dimensional picture of its state.

description: By using electrochemical etching, we fabricated conductive ultrathin SrVO3 (SVO) films that exhibited metallic behavior down to 3 monolayers (ML). From an observed systematic change in transport properties with decreasing film thickness, it was found that the disorder in the films remained nearly unchanged during etching, and only the thickness was reduced. This is in contrast to the insulating behavior found for as-deposited SVO ultrathin films. For the etched films, the electron mobility at 200 K decreased with decreasing film thickness below 10 ML, originating from an increased scattering rate and electron effective mass near the metal-insulator transition. A slight upturn in the resistivity and a positive magnetoresistance at low temperatures were typically observed for the etched films down to 3 ML, which was explained by weak anti-localization of electrons in a weakly disordered metal.

description: The Hubble constant estimated from the combined analysis of the Sunyaev-Zel'dovich effect and X-ray observations of galaxy clusters is systematically lower than those from other methods by 10-15 percent. We examine the origin of the systematic underestimate using an analytic model of the intracluster medium (ICM), and compare the prediction with idealistic triaxial models and with clusters extracted from cosmological hydrodynamical simulations. We identify three important sources for the systematic errors; density and temperature inhomogeneities in the ICM, departures from isothermality, and asphericity. In particular, the combination of the first two leads to the systematic underestimate of the ICM spectroscopic temperature relative to its emission-weighed one. We find that these three systematics well reproduce both the observed bias and the intrinsic dispersions of the Hubble constant estimated from the Sunyaev-Zel'dovich effect.

description: In order to improve the efficiency of multi-crystalline silicon (mc-Si) solar cells, ablation by laser
radiation has been adopted as a non-contact tool for various processes. With ultra-short pulsed laser radiation the
reflectivity of silicon is decreased by altering the surface topology and increases the efficiency of the solar cells. The
formation of structures in the μm-range on the surface of silicon is investigated with respect to the focal diameters at
constant laser parameters. The most promising laser parameters reducing the reflectivity of the solar cells are
identified. Multicrystalline silicon solar wafers with an edge length of 5 inch and a laser generated μm-scale surface
structures, so called “Black Silicon”, were finally processed into cells. The achieved absolute efficiency gain has been
measured to  = 0.21 %.

description: We examine the behavior of the Ramond ground states in the D1-D5 CFT after a deformation of the free-orbifold sigma model on target space $({\mathbb T}^4)^N / S_N$ by a marginal interaction operator. These states are compositions of Ramond ground states of the twisted and untwisted sectors. They are characterized by a conjugacy class of $S_N$ and by the set of their "spins", including both R-charge and "internal" SU(2) charge. We compute the four-point functions of an arbitrary Ramond ground state with its conjugate and two interaction operators, for genus-zero covering surfaces representing the leading orders in the large-$N$ expansion. We examine short distance limits of these four-point functions, shedding light on the dynamics of the interacting theory. We find the OPEs and a collection of structure constants of the ground states with the interaction operators and a set of resulting non-BPS twisted operators. We also calculate the integrals of the four-point functions over the positions of the interaction operators and show that they vanish. This provides an explicit demonstration that the Ramond ground states remain protected against deformations away of the free orbifold point, as expected from algebraic considerations using the spectral flow of the ${\mathcal N} = (4,4)$ superconformal algebra with central charge $c = 6N$.

description: The performance of photovoltaic (PV) modules is generally rated by the power output under standard
test conditions (STC). However, the indoor performance does not necessarily reflect the energy yield under actual
outdoor conditions, because STC is not the representative conditions in most regions. Therefore, it is important to
compare the indoor performance of PV modules under STC with the energy yield at various locations. Research
Center for Photovoltaic Technology (RCPVT) in the National Institute of Advanced Industrial Science and
Technology (AIST) has conducted the outdoor measurements of seven kinds (10 types) of PV modules in AIST
Tsukuba center and AIST Kyushu center. In this study, we estimate the monthly energy yield [kWh] from the initial
power output [kW] and meteorological parameters, which is compared with the monthly energy yield measured by IV
curve tracer. The results indicate that the high-efficiency modules show that the measured energy is several percent
higher than the estimated energy. The measured energy of the conventional silicon modules is almost equivalent to
the estimated energy. The measured energy of the CIGS modules tends to be higher than the estimated energy. The
estimation of thin-film silicon modules is difficult, because of thermal annealing and light soaking effects.

description: Listing dense subgraphs in large graphs plays a key task in varieties of network analysis applications like community detection. Clique, as the densest model, has been widely investigated. However, in practice, communities rarely form as cliques for various reasons, e.g., data noise. Therefore, $k$-plex, -- graph with each vertex adjacent to all but at most $k$ vertices, is introduced as a relaxed version of clique. Often, to better simulate cohesive communities, an emphasis is placed on connected $k$-plexes with small $k$. In this paper, we continue the research line of listing all maximal $k$-plexes and maximal $k$-plexes of prescribed size. Our first contribution is algorithm ListPlex that lists all maximal $k$-plexes in $O^*(γ^D)$ time for each constant $k$, where $γ$ is a value related to $k$ but strictly smaller than 2, and $D$ is the degeneracy of the graph that is far less than the vertex number $n$ in real-word graphs. Compared to the trivial bound of $2^n$, the improvement is significant, and our bound is better than all previously known results. In practice, we further use several techniques to accelerate listing $k$-plexes of a given size, such as structural-based prune rules, cache-efficient data structures, and parallel techniques. All these together result in a very practical algorithm. Empirical results show that our approach outperforms the state-of-the-art solutions by up to orders of magnitude.

Characterization of an antigen-specific T helper cell clone and its products
Creators: name: Kwong, Pearl Chu
Publisher: name: University of British Columbia
Year: 2010

description: A T helper cell clone, referred to as clone 9, was derived from an allogeneic mixed lymphocyte culture. Clone 9, as well as supernatant factor(s) derived from it, could help the cytotoxic T lymphocyte (CTL) responses of H-2 Db (Db) responder cells to alloantigens, or they could help the CTL responses of non- Db responder cells to Db alloantigens. Clone 9 cells or their factor(s) were active only when added during the first 24 hours of a five-day culture period. Clone 9 or its factor(s) could also synergize with interleukin-2 (IL-2)-containing medium in mounting cytotoxic responses to alloantigens. The helper activity in clone 9 supernatant was not due to IL-2 and it was specifically absorbed out by Db -spleen cells. The characterization of the Db -specific helper factor(ASHF) was facilitated by the isolation of a T hybridoma clone (clone 25), obtained from fusion of clone 9 cells with the T cell lymphoma, BW5147, and a B cell hybridoma that produced an IgM monoclonal antibody (clone 30 IgM) which bound ASHF. An additional monoclonal antibody (F23.1), which recognizes a determinant of the Vβ8 family of the T cell receptor, was also particularly useful for the characterization of ASHF. Analysis with these reagents showed that both clone 30 IgM and F23.1 immunoadsorbents could retain ASHF activity. Preabsorption of the ASHF with Db spleen cells prior to affinity purification over a clone 30 IgM column resulted in the absorption of Db-specific helper activity as well as the loss of a 50,000 molecular weight (MW) band on SDS-PAGE under reducing conditions. Furthermore, affinity purification of ASHF over the F23.1 immunoadsorbent, but not an irrelevant monoclonal antibody (mAb) column, also yielded a 50,000 MW molecule. Taken together, these findings suggest that the 50,000 MW molecule is a component of the ASHF and it is intimately related to the B chain of the T-cell receptor. The mode of action of clone 9 and its products in the induction bfCTL responses was also investigated. It was found that clone 9 and ASHF could help CTL responses by inducing IL-2 production in B6-stimulated cultures. In addition to ASHF, clone 9 cells also produced an additional factor(s) which participated in the induction of CTL responses. This additional factor(s) was referred to as IL-X. IL-X synergized with excess human recombinant IL-2 in the activation of CTL precursors (CTL-P) in the absence of antigenic stimulation. A model which involves the participation of ASHF, T helper cells, IL-2 and IL-X in the induction of CTL responses is proposed.

description: The increased sensitivity of future radio telescopes will result in requirements for higher dynamic range within the image as well as better resolution and immunity to interference. In this paper we propose a new matrix formulation of the imaging equation in the cases of non co-planar arrays and polarimetric measurements. Then we improve our parametric imaging techniques in terms of resolution and estimation accuracy. This is done by enhancing both the MVDR parametric imaging, introducing alternative dirty images and by introducing better power estimates based on least squares, with positive semi-definite constraints. We also discuss the use of robust Capon beamforming and semi-definite programming for solving the self-calibration problem. Additionally we provide statistical analysis of the bias of the MVDR beamformer for the case of moving array, which serves as a first step in analyzing iterative approaches such as CLEAN and the techniques proposed in this paper. Finally we demonstrate a full deconvolution process based on the parametric imaging techniques and show its improved resolution and sensitivity compared to the CLEAN method.

description: We solve exactly the Schrödinger equation for the free-particle, the pseudo-harmonic oscillator and the Mie-type potential in three dimensions with the Dunkl derivative. The equations for the radial and angular parts are obtained by using spherical coordinates and separation of variables. The wave functions and the energy spectrum for these potentials are derived in an analytical way and it is shown that our results are adequately reduced to those previously reported when we remove the Dunkl derivative parameters.

description: It has been analyzed that the local strain fields and the intermixing around Ge quantum dots (QDs) in
the Si spacer by electron microscopy. HAADF-STEM images clearly show the intermixing between Ge and Si as
well as the surface segregation of Ge become advanced. The average composition of the QDs is Geo.43Si0.57, which is
almost constnt in a row of vertically aligned QDs. The local strain analysis obtained from the high-resolution TEM
images shows that the strain state is remained after the elastic relaxation of QDs, however, most of the strain state has
relaxed.

description: Homomorphic secret sharing (HSS) allows multiple input clients to secret-share their data among multiple servers such that each server is able to locally compute a function on its shares to obtain a partial result and all partial results enable the reconstruction of the function's value on the outsourced data by an output client. The existing HSS schemes for {\em high-degree} polynomials either {\em require a large number of servers} or {\em lack verifiability}, which is essential for ensuring the correctness of the outsourced computations. In this paper, we propose a two-server verifiable HSS (VHSS) model and construct a scheme that supports the computation of high-degree polynomials. The degree of the outsourced polynomials can be as high as a polynomial in the system's security parameter. Despite of using only 2 servers, our VHSS ensures that each single server learns no information about the outsourced data and no single server is able to persuade the client to output a wrong function value. Our VHSS is significantly more efficient. When computing degree-7 polynomials, our scheme could be 3-10 times faster than the previously best construction.

description: Several roadmaps e.g. the ITRPV forecast an increasing demand of automation in asking for higher
outputs in combination with close to 100% yield [1]. Twice the output of today’s production lines will affect the
construction and performance of the actual process equipment as well as the handling and transportation solutions
within a factory.
During the transport of substrates, especially on conveyor belt systems, a misalignment cannot completely be
prevented. The passive alignment of wafers and cells is the most cost effective one in terms of investment. Active
alignment systems nevertheless replaced such simple systems more often due to the fear of breakage and the
complexity of adjustments.
The choice of the right combination of materials and geometry of the passive alignment elements is of upmost
priority for the resulting system and its functionality. Therefore, several materials as well as different design and
construction approaches were investigated.

description: The multi-scale flow mechanism is crucial for force and heat loaded on near-space and reentry vehicles, the control of spacecraft by thrusters, the propelling and cooling of MEMS, etc. Since the continuum flow and rarefied flow often exist simultaneously, the modeling and prediction for such a multi-scale flow field is very complicated. One important and efficient way of predicting the multi-scale flow is constructing numerical methods by adapting the multi-scale properties of the temporal integral solutions (or equivalent characteristic line solutions) for the model equations in the gas-kinetic theory. The model equations can be classified into FP-type and BGK-type, and the numerical methods can have deterministic form or stochastic particle form. Since these numerical methods are strictly based on model equations, they are also restricted by the model equations. The difficulty and complexity in constructing model equation that has complete asymptotic preserving property for gas mixture with non-equilibrium internal energy will prevent the further extension of these methods. Therefore, this paper addresses the question whether a multi-scale numerical method can be established not on the model equations, but directly adapts the relaxation rates of macroscopic variables such as stress and heat flux. Since the algorithm of multi-scale particle method based on BGK-type equation is clear and simple, its collision step is modified in this work, where the macroscopic variables firstly evolve according to their relaxation rates, and then the molecules that participate in inter-molecular collisions get their after-collision velocities from the after-evolution macroscopic variables. Therefore, this direct relaxation process does not depend on the model equations anymore. Finally, the validity and accuracy of the particle method with direct relaxation process are examined with five test cases.

Environmental performance of shared micromobility and personal alternatives using integrated modal LCA

description: The environmental performance of shared micromobility services compared to private alternatives has never been assessed using an integrated modal Life Cycle Assessment (LCA) relying on field data. Such an LCA is conducted on three shared micromobility services in Paris - bikes, second-generation e-scooters, and e-mopeds - and their private alternatives. Global warming potential, primary energy consumption, and the three endpoint damages are calculated. Sensitivity analyses on vehicle lifespan, shipping, servicing distance, and electricity mix are conducted. Electric micromobility ranks between active modes and personal ICE modes. Its impacts are globally driven by vehicle manufacturing. Ownership does not affect directly the environmental performance: the vehicle lifetime mileage does. Assessing the sole carbon footprint leads to biased environmental decision-making, as it is not correlated to the three damages: multicriteria LCA is mandatory to preserve the planet. Finally, a major change of paradigm is needed to eco-design modern transportation policies.

description: This paper presents the design, fabrication, and experimental characterization of a peristaltic micropump. The micropump is composed of two layers fabricated from polydimethylsiloxane (PDMS) material. The first layer has a rectangular channel and two valve seals. Three rectangular mini lightweight piezo-composite actuators are integrated in the second layer, and used as actuation parts. Two layers are bonded, and covered by two polymethyl methacrylate (PMMA) plates, which help increase the stiffness of the micropump. A maximum flow rate of 900 mokroliter per min and a maximum backpressure of 1.8 kPa are recorded when water is used as pump liquid. We measured the power consumption of the micropump. The micropump is found to be a promising candidate for bio-medical application due to its bio-compatibility, portability, bidirectionality, and simple effective design.

description: In many classical e-commerce platforms, personalized recommendation has been proven to be of great business value, which can improve user satisfaction and increase the revenue of platforms. In this paper, we present a new recommendation problem, Trigger-Induced Recommendation (TIR), where users' instant interest can be explicitly induced with a trigger item and follow-up related target items are recommended accordingly. TIR has become ubiquitous and popular in e-commerce platforms. In this paper, we figure out that although existing recommendation models are effective in traditional recommendation scenarios by mining users' interests based on their massive historical behaviors, they are struggling in discovering users' instant interests in the TIR scenario due to the discrepancy between these scenarios, resulting in inferior performance. To tackle the problem, we propose a novel recommendation method named Deep Interest Highlight Network (DIHN) for Click-Through Rate (CTR) prediction in TIR scenarios. It has three main components including 1) User Intent Network (UIN), which responds to generate a precise probability score to predict user's intent on the trigger item; 2) Fusion Embedding Module (FEM), which adaptively fuses trigger item and target item embeddings based on the prediction from UIN; and (3) Hybrid Interest Extracting Module (HIEM), which can effectively highlight users' instant interest from their behaviors based on the result of FEM. Extensive offline and online evaluations on a real-world e-commerce platform demonstrate the superiority of DIHN over state-of-the-art methods.

description: Recently, Giraitis et al. (2003, [10]) proposed the $V/S$ statistic for testing long memory in random sequences. We generalize this statistic to the setting of random fields. The null hypothesis is concerned with short memory random fields while the alternative contains a very large family of long memory random fields. Contrary to most of the previous works dealing with long-range dependence, no assumption is made about the isotropy of the strong dependence. Some simulations are presented in order to assess the power of the test according to the kind of long memory in presence.
