description: We give a Las Vegas algorithm which computes the shifted Popov form of an $m \times m$ nonsingular polynomial matrix of degree $d$ in expected $\widetilde{\mathcal{O}}(m^ωd)$ field operations, where $ω$ is the exponent of matrix multiplication and $\widetilde{\mathcal{O}}(\cdot)$ indicates that logarithmic factors are omitted. This is the first algorithm in $\widetilde{\mathcal{O}}(m^ωd)$ for shifted row reduction with arbitrary shifts. Using partial linearization, we reduce the problem to the case $d \le \lceil σ/m \rceil$ where $σ$ is the generic determinant bound, with $σ/ m$ bounded from above by both the average row degree and the average column degree of the matrix. The cost above becomes $\widetilde{\mathcal{O}}(m^ω\lceil σ/m \rceil)$, improving upon the cost of the fastest previously known algorithm for row reduction, which is deterministic. Our algorithm first builds a system of modular equations whose solution set is the row space of the input matrix, and then finds the basis in shifted Popov form of this set. We give a deterministic algorithm for this second step supporting arbitrary moduli in $\widetilde{\mathcal{O}}(m^{ω-1} σ)$ field operations, where $m$ is the number of unknowns and $σ$ is the sum of the degrees of the moduli. This extends previous results with the same cost bound in the specific cases of order basis computation and M-Padé approximation, in which the moduli are products of known linear factors.

title: Investigations into the application of engineered bamboo for future hybrid beams

description: Over the late decade, sustainability has become mainstream in the built environment due to the widespread awareness of global warming. This has led to the creation and optimisation of engineered wood and bamboo products. Engineered bamboo products possess superior environmental and mechanical characteristics which situate them as appealing candidates in aiding other natural building materials in the path toward sustainability. Whilst many of the studies in this ﬁeld have only focused on characterising engineered bamboo products, this study aimed to develop engineered bamboo-based composite beams. A prototyping study was conducted to gain a detailed understanding of the proposed hybrid/engineered materials, with a focus on enhancing the strength and retaining the environmental and mechanical characteristics of both materials. A series of destructive experiments were conducted to evaluate the mechanical properties of the constituent materials and a simpliﬁed stress-strain relationship was proposed. A tailor-made and multi-point measurement system based on photogrammetry was developed to acquire three-dimensional information. Using this information, the suitability of the timber-based testing standards for laminated bamboo were examined and the limitations were identiﬁed. Three different composite prototypes were fabricated and tested in three stages in the laboratory environment at Edinburgh Napier University. These composites are: I-bone laminated bamboo and timber hybrid beam (IBHB), laminated bamboo I beam (BIB) and laminated bamboo double I-beam (BDIB).Throughout the different stages of this study, engineered bamboo-based composite beams have shown promising potential to be used in the construction industry. Because of their rapid renewability, great strength and higher ductility, these composites are efﬁcient in terms of material use and comprise more than three times higher strength to weight ratio compared to the control samples. Mathematical models to predict the deﬂection and bending moment were developed based on the linear and non-linear behaviour of laminated bamboo. The I-bone laminated bamboo provided higher load-bearing capacity while the side timbers contributed toward shear resistance and cross-sectional stability. IBHB exhibited higher ﬂexural strength when compared to the conventional engineered wood materials. The bending modulus of IBHB was also doubled when compared to the control samples. The laminated bamboo I-beam and double I-beam also demonstrated great ﬂexural properties, however, with signs of vulnerability to the horizontal shear failure. Laminated bamboo double I-beam exhibited similar mechanical properties to those of IBHB. The ﬁndings of this study add to the rapidly expanding ﬁeld of engineered bamboo applications within the future built environment. It has done so by providing an innovative approach to developing new engineered bamboo composites for construction and provides a strong foundation for future research.

COMMENTS: Rand cited the AMNH number of the holotype in the original description and listed two males (including the type) and four females from Mafulu, one male from the Aroa River, and one immature female from the Hydrographer Range. Paratypes in AMNH are: Mafulu, females, AMNH 421093, collected 24 October 1933; AMNH 421348, collected 8 October 1933; AMNH 421349, collected 1 November 1933; head of Aroa River, male, AMNH 695829, collected 15 May 1905; Hydrographer Range, female, AMNH 695830, collected 25 February 1918. Rand did not give AMNH catalog numbers for specimens other than the type, and I have not found, in either the collection or the catalog, one male and one female paratype listed for this subspecies from Mafulu.

description: Photovoltaic is becoming more and more important in Italy. Promoting tariffs, introduced
with the “Conto energia” Programme have provided the basis for the expansion of PV market that today
correspond to a cumulative capacity of about 1500 MW, with an increase of 150% as respect to the
previous year.
Such growth has been also been driven by a consistent system price decreased of both large free standing
applications and small rooftop systems. On the contrary, the growth of the market has not been
accompanied by an adequate growth of the national photovoltaic industry that has produce only a small
share of the installed products. Also public and private budget for research and demonstration initiatives
remain flat with respect to the previous years and very small compared to the budget allocated for
promoting tariffs.

description: The freezeout conditions in proton-proton collisions at $\sqrt{s_{\textrm{NN}}}= 200$, $900$ and $7000$ GeV have been extracted by fits to the mean hadron yields at mid-rapidity within the framework of the statistical model of an ideal gas of hadrons and resonances in the grand canonical ensemble. The variation of the extracted freezeout thermal parameters and the goodness of the fits with $\sqrt{s_{\textrm{NN}}}$ are discussed. We find the extracted temperature and baryon chemical potential of the freezeout surface to be similar in p+p and heavy ion collisions. On the other hand, the thermal behaviour of the strange hadrons is qualitatively different in p+p as compared to A+A. We find an additional parameter accounting for non-equilibrium strangeness production is essential for describing the p+p data. This is in contrast to A+A where the non-equilibrium framework could be successfully replaced by a sequential and complete equilibrium model with an early freezeout of the strange hadrons.

description: How extracellular electric fields, as generated endogenously or through transcranial brain stimulation, affect the dynamics of large neuronal populations is of great interest but not well understood. To study the collective dynamics of large populations single-compartment (point) model neurons have been proven very successful. These models, however, lack the dendritic morphology to biophysically account for the effects of electric fields, and for changes in synaptic integration due to morphology alone. Here we (i) characterize the response of a canonical spatial (ball-and-stick) model neuron to fluctuating synaptic input as well as an oscillatory, weak electric field, and (ii) analytically derive an extension for popular integrate-and-fire point neuron models to accurately reproduce these responses. We obtain distinct filters mediated by the dendrite for inputs at the soma (high-pass filter) or at the distal dendritic site (low-pass filter), and find that the electric field induces spike rate resonance in the beta and gamma frequency bands or even higher frequencies, depending on the location of synaptic background input. Due to their computational efficiency the extended point models are well suited for application in large populations of coupled neurons with different morphology, exposed to extracellular electric fields.

title: A feasibility study of development and implementation of smart energy system for 100% renewable energy and transport solutions in Sri Lanka
Creators: name: Fernando, Wattala P. R. S. S.

description: Sri Lanka as a developing country is facing existential energy challenges. Total electricity consumption was 12.79 TWh in 2016 and is projected to increase about 6 times to 71.97 TWh by 2050. The projected energy demand will exceed supply in a few years. A transition to 100% renewable energy (100RE) supply will address fuel security, and environmental concerns. This study investigates the potential quantity of renewable energy sources in Sri Lanka for a transition to a 100RE future. This thesis reports a detailed feasibility study framework and case studies for the development and implementation of 100% renewable energy supplied Smart Energy Systems and Transport future for Sri Lanka. The feasibility study framework and the case study analyses are based on a long-term energy system model of Sri Lanka using the EnergyPLAN model. Sri Lanka should have a potential install capacity of grid-connected wind, solar photovoltaic, dammed hydro, river hydro and biomass to achieve 100% renewable energy solution, and the estimated values are 14430 MW, 15600 MW, 1576 MW, 753 MW and 394 MW, respectively. Different development scenarios towards 100RE are used to study the pathway towards 100RE. These scenarios are based on a staged increase of renewable energy such as biomass. The scenarios also include conversions to electrical vehicles, waste to energy, H2 usage and dump charge system for transport. The results prove that a pathway for 100RE is possible. The 100RE pathway ensures energy security and mitigates environmental impacts. The pathway includes improvements in industrial energy intensity and utilising efficiency and conservation potentials. Fuel demand for the industry will be supplied through a high share of biomass usage. Bioenergy and electrification integration are key to the solution, all remaining fuel consumption is converted to solid biomass. The results show that there are technically feasible pathways to achieve 100RE solutions for Sri Lanka with the present and predicted renewable energy technologies. Sri Lanka can meet the future energy demand without importing energy with the complementary socio-economic and socio-political approaches.

description: A solar cell format of 156 x 39 mm is proposed and tested for multicrystalline silicon solar cells. These
so called “QuarterCells” are made from standard wafers of 156 x156 mm, but with a modified front and back
metallization pattern. The rectangular format allows an interconnection of the cells with short, thin pieces of wire.
This results in lower shading of active silicon area and in much lower resistive losses between the cells, such that a
total gain in power output of 4.4% is expected. Simultaneously the copper needed for the interconnection of cells is
reduced by more than 50%. First tests on real modules confirm the expected advantages.

description: Aims: To study circulating levels and distribution of adiponectin multimers [low molecular weight (LMW)-, medium molecular weight (MMW)- and high molecular weight (HMW)-adiponectin] in preterm and full-term infants. Methods: Total serum adiponectin and its multimers were measured in 40 healthy infants at the age of one month and associations with anthropometric parameters [body weight and length, body mass index (BMI)], weight gain and metabolic indices (glucose, insulin) were examined. Twenty of the infants were born preterm (gestational age 33.2±1.6 weeks). Results: LMW-adiponectin level and its fractional ratio to total adiponectin were significantly higher in full-term than in preterm infants (P<0.001 and P<0.01, respectively), whereas, MMW-adiponectin level and its ratio were significantly lower (P=0.03 and P=0.01, respectively). HMW-adiponectin did not differ significantly between full-term and preterm infants and accounted for almost 60% of total adiponectin levels in both groups. HMW-adiponectin, but not MMW adiponectin or LMW adiponectin, correlated significantly with anthropometric measurements, similarly to total adiponectin; in addition, HMW adiponectin correlated significantly with weight gain. Conclusions: HMW adiponectin is the most prevalent form in infants. Circulating levels and distribution of MMW- and LMW-adiponectin differ between full-term and preterm infants, but the role of these adiponectin multimers needs to be studied further.
title: New approaches to studying the GPI biosynthesis pathway in T. brucei: uncovering the missing links
titleType: Other
Creators: name: Ji, Zhe
Publisher: name: University of Dundee
Year: 2021

description: Trypanosoma brucei is a protozoan that causes Human African Trypanosomiasis and nagana in cattle. The bloodstream form (BSF) of T. brucei has a dense surface-coat of variant surface glycoprotein (VSG) that acts as the first line of defence against the host immune system while the main cell surface glycoproteins of the procyclic form (PCF) are the procyclins. VSGs and procyclins are attached to the cell membrane through glycosylphosphatidylinositol (GPI) anchors. Despite its importance, the  GPI biosynthetic pathway in T. brucei is not fully elucidated.

In this thesis, we have applied epitope tagging, chemical crosslinking and quantitative proteomics methods to look for new components of protein complexes of the GPI pathway. Three components of the pathway were tagged and immunoprecipitated with or without chemical crosslinking and the results were as follows:

For TbGPI12, the GlcNAc-PI de-N-acetylase, we discovered that, contrary to expectations, it is not complexed with TbMTI but with a different potential partner protein. We also optimised methodologies in this part of the study.

For the TbGPI3 component of GPI GnT, we identified its expected partner proteins TbGPI15, TbGPI19, TbGPI2, TbGPI1 and TbERI1 and also identified two new components of the complex, namely an Arv1-like protein (TbArv1) and a putative E2-ligase.

For the GPI inositol deacylase (TbdeAc2) that catalyses inositol deacylation of GPI intermediates, we showed that it is present in  a ~240 kDa complex and, using both crosslinking and stable isotope in cell culture (SILAC) methodology, identified partner protein(s) encoded by genes Tb927.11.11740 and/or Tb927.11.11750. Individual reverse pull-down experiments showed that only Tb927.11.11750 was directly associated with TbdeAc2. Our attempts to generate a null and conditional null mutant for Tb927.11.11750 were not successful. However, we considered the possibility that Tb927.11.11750 (which contains a lipase motif) encodes a GPI PLA2 enzyme; an activity adjacent to TbdeAc2 in the pathway. We therefore used immunoprecipitated Tb927.11.11750 in an in vitro assay for GPI PLA2 activity using a radiolabelled and purified glycolipid A’ substrate. However, no GPI-PLA2 activity could be detected under the conditions used. Taken together, we postulate that Tb927.11.11750 encodes an essential product for the survival of BSF T. brucei and hypothesise that the Tb927.11.11750 protein may be required for stabilisation and/or regulation of TbdeAc2.

description: Neutral long-lived particles (LLPs) are highly motivated by many BSM scenarios, such as theories of supersymmetry, baryogenesis, and neutral naturalness, and present both tremendous discovery opportunities and experimental challenges for the LHC. A major bottleneck for current LLP searches is the prediction of SM backgrounds, which are often impossible to simulate accurately. In this paper, we propose a general strategy for obtaining differential, data-driven background estimates in LLP searches, thereby notably extending the range of LLP masses and lifetimes that can be discovered at the LHC. We focus on LLPs decaying in the ATLAS Muon System, where triggers providing both signal and control samples are available at the LHC Run-2. While many existing searches require two displaced decays, a detailed knowledge of backgrounds will allow for very inclusive searches that require just one detected LLP decay. As we demonstrate for the $h \to X X$ signal model of LLP pair production in exotic Higgs decays, this results in dramatic sensitivity improvements for proper lifetimes $\gtrsim 10$ m. In theories of Neutral Naturalness, this extends reach to glueball masses far below the $\bar b b$ threshold. Our strategy readily generalizes to other signal models, and other detector subsystems. This framework therefore lends itself to the development of a systematic, model-independent LLP search program, in analogy to the highly successful simplified-model framework of prompt searches.

description: A novel type of system for the deposition of ALD Al2O3 films is described. Wafers are transported in a
linear track, floating on gas bearings without any physical contact with the track walls. During transport the wafers
pass segments in which they come in contact with sequentially TMA, N2, H2O and N2. The system is made up of a
large quantity of such ALD cells, each of which has a typical length of 12cm; in each of these cells 0.12nm Al2O3 is
deposited. The dimensions of the pre-cursor injection lines and the pressures and flows are selected such that no
mixing of the precursors take place inside the system. This results in a system that operates under atmospheric
conditions with a throughput of 3600 wafers per hour, with easy automation, no moving parts (except the wafers) and
no deposition on the track walls.
Al2O3 films with thicknesses in the range 5-24nm were deposited with the following electrical performance: effective
lifetimes on 200 μm thick FZ wafers in the range 1.5-2.5ms, dropping to 0.6-0.8ms after a firing-type anneal and on
CZ wafers 0.2-0.7ms after firing.

description: The separation of wafers after the sawing process is still a challenge for automation. In recent years,
numerous equipment suppliers have invested considerable efforts to meet the customer needs in terms of throughput,
uninterrupted processing and high yield. Additionally, some wafer manufacturers have developed their own
proprietary solutions. However, the mechanical stress on the wafer still needs to be reduced. Furthermore, a greater
flexibility is required to cope with different wafer thicknesses. Recent work therefore focused on a new solution in
which the separation process is solely based on water-jets separating and transporting the single wafer. This method
was chosen to reduce the mechanical stress on the wafer and at the same time to enable the work with different
thicknesses of wafers.

description: We study the masses of open charm and bottom tetraquark states within the diquark-antidiquark scenario in the relativized quark model proposed by Godfrey and Isgur. The diquark and antidiquark masses are firstly solved by relativized quark potential, and then treated as the usual antiquark and quark, respectively. The masses of tetraquark states are obtained by solving the Schrödinger-type equation between the new diquark and antidiquark. We find the masses of $sq\bar b\bar q$ tetraquark configuration are much higher than that of $X(5568)$. This conclusion disfavors the possibility of $X(5568)$ as a tetraquark state within the diquark-antidiquark scenario. Further experimental searches are needed to clarify the nature of the signal observed by D0 collaboration.

See Diamond, 1972: 367–370, Dickinson, 2003: 433, and Higgins et al., 2008: 593. HOLOTYPE: AMNH 448977, adult male, collected on Hunstein Peak (5 Huntsteinspitze), 04.30S, 142.40E (USBGN, 1943), Hunstein Mountains, East Sepik Province, Papua New Guinea, on 2 March 1913, by Joseph Bürgers (no. 1364). From the Rothschild Collection. COMMENTS: Rand gave the AMNH number of the holotype in the original description and noted that he based his description on eight males and three females from Hunstein Peak. The holotype came to AMNH via the Rothschild Collection but was cataloged separately as Rand named this form before the Rothschild specimens of Meliphagidae were cataloged. However, no other Hunstein Peak specimens of this form came to AMNH. Perhaps Rand borrowed specimens from ZMB, where the bulk of the Bürgers Collection is housed. Stresemann (1923: 58) reported that one specimen of Meliphaga montana was collected at Maeanderberg and 22 specimens on Hunstein Peak. The holotype of sepik is also a paratype of germanorum, see below.

description: The objective of this work has been to identify the root cause of the reduced etch rate of fixed abrasive
sawing (FAS) cut wafers during damage etching. The etch rate in alkaline solutions was measured as a function of
time, temperature and different pre-cleaning processes, both for FAS and standard slurry wafers. The results showed
a maximum etch rate for KOH concentrations around 20-30 wt%. The etch rate of FAS wafers was lower compared
to slurry wafers during the initial 5-10 minutes of etching, dependent upon KOH concentration and temperature. In
order to characterize the wafer surface, scanning electron microscopy (SEM), transmission electron microscopy
(TEM), atomic force microscopy (AFM), as well as reflectance measurements were used. By comparing the cross
sections of the surface structure of as cut slurry and as cut FAS wafers, both an amorphous silicon layer and a defect
layer were observed, but is concluded to not limiting initial higher etch rate. Furthermore during the initial stage of
damage etching inverted square pillars were always formed. The walls of the pillars were constructed by the fast
etching {110} planes. The depth of the pillars is found to be shallower for FAS cut wafers due to initially lower
surface roughness. Therefore, the surface area exposed for the damage etch solution is larger for the slurry cut wafers,
which explains the larger etching rate for the slurry cut wafers during the initial stage of the etching.

title: An investigation of university and employer perceptions of barriers and enablers of work based learning (WBL) partnerships in the tourism sector in Scotland
Creators: name: Waterston, Lynn
Publisher: name: Edinburgh Napier University
Year: 2020

description: The purpose of this study is to enhance understanding of how universities and employers in the Scottish tourism sector collaborate when developing work based learning (WBL) partnerships and the associated barriers and enablers. The findings aim to inform practice on how collaboration in this area can be enhanced.
The impetus for the research arose from the requirement for universities to develop and enhance links with industry, in line with government policies linked to driving graduate employability. WBL is identified as having a key influence on how well graduates are prepared for the world of work. Consequently, effective university/industry WBL partnerships are essential in providing opportunities for university students to develop their employability skills in order to enhance their future graduate employment prospects. The issue of university/industry partnerships is documented in academic literature; however, there is a lack of research with a focus on the particular and complex characteristics of WBL partnerships. Furthermore, this issue in relation to the tourism sector is not well represented in the literature.
The study adopted an interpretivist ontology and an epistemology of phenomenology. A purposive sampling approach was undertaken to identify employees with responsibility for industry liaison in Scottish universities who offer Tourism and Hospitality degree programmes with a WBL offering. This approach was also adopted to select employers from the Scottish tourism sector with experience of developing WBL linkages with Scottish universities.
In-depth semi-structured interviews enabled respondents to provide detailed accounts of their experiences of how WBL partnerships are developed and managed around the themes drawn from the literature: characteristics of successful university-employer partnerships; employer engagement in the WBL relationship; barriers to achieving effective employer/university partnerships; expectations; enablers of positive university/employer relationships and best practice in university/employer relationships.
The main output from this research is a practice- based framework which outlines key elements for effective relationship management of WBL. The framework provides universities and employers with valuable guidelines on how their practice in this area may be enhanced. Key findings indicate the need for an increased level of priority for developing WBL partnerships with clear aims and objectives to be established at the outset; enhanced communication between universities and employers; additional resources for universities in terms of staffing and funding and more flexible WBL opportunities to meet the needs of employers. For employers in the tourism sector, it was found that a more proactive approach to WBL partnerships may be beneficial as part of their recruitment and retention strategies.

description: The Helianthos roll-to-roll technology makes use of a temporary Al substrate to deposit high quality
SnO2:F and a-Si:H and μc-Si:H layers. The unique characteristics of the roll-to–roll process allow making a series of
solar cell modules with continuous variable Si-layer thickness in the roll. When this is done for the i-layer – while
keeping the adjacent doped layers at normal thickness – the solar cells performance as function of thickness can be
studied in great detail. In that way the thickness influence of μc-Si:H bottom cell in a tandem device is elucidated. As
is expected the p/i interface plays an important role.
By understanding the limiting factors and optimizing the device by striving for a constant material quality over the
thickness of the device an 8.9% aperture area stabilized completely roll-to-roll produced module of 840 cm2
corresponding with a 9.4% active area stabilized efficiency was achieved.

description: Sensitive detection of weak magnetic moments is an essential capability in many areas of nanoscale science and technology, including nanomagnetism, quantum readout of spins, and nanoscale magnetic resonance imaging. Here, we show that the write head of a commercial hard drive may enable significant advances in nanoscale spin detection. By approaching a sharp diamond tip to within 5 nm from the pole and measuring the induced diamagnetic moment with a nanomechanical force transducer, we demonstrate a spin sensitivity of 0.032 Bohr magnetons per root Hz, equivalent to 21 proton magnetic moments. The high sensitivity is enabled in part by the pole's strong magnetic gradient of up to 28 million Tesla per meter and in part by the absence of non-contact friction due to the extremely flat writer surface. In addition, we demonstrate quantitative imaging of the pole field with about 10 nm spatial resolution. We foresee diverse applications for write heads in experimental condensed matter physics, especially in spintronics, ultrafast spin manipulation, and mesoscopic physics.

description: a-SiCx films are used for the electrical passivation of the rear surface of high-efficiency PERC silicon
solar cells. The films comprise intrinsic as well as n- and p-doped SiCx layers prepared by adding PH3 or B2H6 to the
precursor gases during the Plasma Enhanced Chemical Vapor Deposition (PECVD) process. Two different rear
contacting approaches, Laser Fired Contacts (LFC) and plasma etched rear openings with subsequent aluminium
evaporation, are used to reveal the impact of the different rear passivation schemes on the solar cell performance.
The results indicate that intrinsic and lightly n-doped SiCx layers are well suited for the passivation of highefficiency
silicon solar cells, yielding cell efficiencies of up to 20.7%. Furthermore the floating junction behavior of
the n-SiCx passivation scheme could be verified, leading to a complete depassivation of the rear side in the case of
the LFC approach due to shunting of the rear diode by the aluminium contacts.

description: The tremendous expansion of the photovoltaic technology and its relative avidity for silicon is
producing a dramatic change in the polysilicon industry structure, increasing the efforts to produce a low cost, high
quality Solar Silicon. In this context, the Centro de Tecnología del Silicio Solar (CENTESIL) was founded in 2006
as a private-public partnership venture, and is currently building a 50 t/a pilot plant for silicon purification following
the chlorosilane route. Although an advanced state of the art technology has been selected as first choice, the purpose
is to be able to undertake developments in any topic that has the potential to reduce the cost effectively. Additionally,
the project includes facilities for monocrystalline growth and wafering, and also the solar cell processing line of the
Instituto de Energía Solar, so that it will cover the whole value chain from feedstock to solar cell.

description: The 1D Vlasov-Poisson system is the simplest kinetic model for describing an electrostatic collisonless plasma, and the BGK waves are its famous exact steady solutions. They play an important role on the long time dynamics of a collisionless plasma as potential "final states" or "attractors", thanks to many numerical simulations and observations. Despite their importance, the existence of stable BGK waves has been an open problem since their discovery in 1958. In this paper, first linearly stable BGK waves are constructed near homogeneous states.
