description: We reexamine generation of the primordial magnetic fields, at temperature $T>80$TeV, by applying a consistent kinetic theory framework which is suitably modified to take the quantum anomaly into account. The modified kinetic equation can reproduce the known quantum field theoretic results upto the leading orders. We show that our results qualitatively matches with the earlier results obtained using heuristic arguments. The modified kinetic theory can give the instabilities responsible for generation of the magnetic field due to chiral imbalance in two distinct regimes: a) when the collisions play a dominant role and b) when the primordial plasma can be regarded as collisionless. We argue that the instability developing in the collisional regime can dominate over the instability in the collisionless regime.

description: We show that the stable cohomology of automorphism groups of free groups with coefficients obtained by applying Hom(-,-) to tensor powers of the abelianization, is equipped with the structure of a wheeled PROP H. We define another wheeled PROP E by Ext-groups in the category of functors from the category of finitely generated free groups to k-modules. The main result of this paper is the construction of a morphism of wheeled PROPs $ϕ: E \to H$ such that $ϕ(E)$ is the wheeled PROP generated by the cohomology class h_1 constructed by the first author.

Technology architecture: the discipline for the future definition of a manifesto
Creators: name: Peretti, Gabriella
Publisher: name: TECHNE - Journal of Technology for Architecture and Environment
Year: 2011

description: The author proposes a reflection on the evolution and possible future developments of Architectural Technology as an academic discipline, in light of its historical roots, through a path that sees it divided into different areas of specialized knowledge, all heavily characterized by attention to the methodological aspects in the project. Faced with potential developments, the author identifies two alternatives: one aimed at consolidating specialized aspects according to a plural vision of technologies, the other aimed at reconstructing a uni- que integrated discipline. The author takes the second direction, proposing to guide Archi- tectural Technology, in research and training, towards the construction of generalized skills, albeit with controlled specificities, that support the project’s capacity to direct.

description: The current study analyzed 212 college students’ decisions to express or suppress negative feelings about the extent to which others enact recommended COVID-19 precaution behaviors. Using a phronetic iterative analysis, participant experiences were examined in terms of (a) choices to express or suppress their negative feelings and (b) the reasons underlying their disclosure decisions. Significant themes emerged with both response categories. The themes and study findings are discussed in relation to privacy management, subjective norms, and bystander intervention work. Further implications of these findings are also discussed in their extension of and relevance to existing work on compliance-centered interventions and disclosure decisions in health-related contexts.

description: Abstract: Background: In 2011, seven decentralized Public Health Regional Surveillance Teams (PHRSTs) were restructured into four centralized Public Health Preparedness and Response (PHP&R) regional offices to realign preparedness priorities and essential services with appropriate infrastructure; field-based staff was reduced, saving approximately $1 million. The objective of this study was to understand the impact that restructuring had on services provided to local health departments (LHDs) throughout North Carolina. Methods: A survey to document services that regional offices provide to LHDs in North Carolina was administered by the North Carolina Preparedness and Emergency Response Research Center in 2013. The results were compared to a similar survey from 2009, which identified services provided by regional teams prior to restructuring. Results: Of 69 types of assistance, 14 (20%) were received by 50% or more LHDs in 2012. Compared to 2009, there was a significant decrease in the proportion of LHDs receiving 67% (n = 47) of services. The size of the region served by regional offices was shown to inversely impact the proportion of LHDs receiving services for 25% of services. There was a slight significant decline in perceived quality of the services provided by regional teams in 2012 as comparison to 2009. Conclusions: Following a system-wide review of preparedness in North Carolina, the state’s regional teams were reorganized to refine their focus to planning, exercises, and training. Some services, most notably under the functions of epidemiology and surveillance and public health event response, are now provided by other state offices. However, the study results indicate that several services that are still under the domain of the regional offices were received by fewer LHDs in 2012 than 2009. This decrease may be due to the larger number of counties now served by the four regional offices.

description: Determination of major specialization is important to lead the student to focus on areas of study that are of interest as well as in accordance with its academic credentials. Currently, the determination of major specialization is done by asking directly to students, regardless of academic outcomes that have been achieved in the previo us semester. This study discusses the development of a hybrid model from fuzzy Mamdani and C4.5 algorithm to analyze the determination of major specialization in informatics engineering courses of Universities Raya Serang, where C4.5 algorithm is used as a shaper rule (rule) which is used in the inference stage. Establishment of rules (decision tree) performed using Weka applications, while for the determination of the decision support analysis specialization majors using Mamdani fuzzy concept, the application is done using the help of MATLAB. The results showed that 17 of the 126 students who either choose according to variable concentrations used in this study.

Simple Systems - Complex Capacities. Integrative Processes of Computational Morphogenesis in Architecture
Creators: name: Menges, Achim
Publisher: name: TECHNE - Journal of Technology for Architecture and Environment
Year: 2011

description: The complexity of the cultural, social, economical and particularly ecological context in which architecture is practised today necessitates design strategies and tactics that achieve a high level of integration of seemingly opposed demands and criteria within the material and construction systems we design. One possibility of unfolding novel synergies in such extreme conditions is to utilize the capacity of computers in the design process in an alternative way, one that foregrounds and instrumentalizes the innate capacities of materials, manufacturing and construction processes rather than merely elaborating form in the digital realm. The computational approach that will be presented here questions the nature of current design processes, but it is not a call for the replacement of the architect by computer driven design. Rather, under this approach, architects, instead of creating exuberant shapes subsequently rationalised for constructability and superimposed functions, are able to define specific material and construction systems by the combined logics of formation and materialisation encoded in generative processes of computational morphogenesis.

description: To monitor the acidity of rain water in real time, a rain water sampling system was developed. The rain sampler detects the initial rain after a dry spell and collects a water sample. Before performing the measurements, the pH probe is calibrated using a standard buffer solution whereas the conductivity probe is calibrated using deionized water. After calibrating the probes the pH and the conductivity of the collected rain water sample are measured using the pH and the conductivity probe. Weather parameters such as air temperature, humidity and pressure are also recorded simultaneously. The pH and conductivity measurement data including weather parameters are transmitted to central station using a GSM modem for further analysis. The collected rain water sample is preserved at the remote monitoring station for post chemical analysis. A programmable logic controller controls the entire process.

description: The topic of project as product of research for the Area of Architecture can be considered therefore central for tradition, for the recognized value on social, economic and environmental effects of the works of architecture and, finally, for the declared accreditation from scientific bodies and evaluation structures of Athenaeums. As it is not reasonable to imagine an automatic correspondence between project and its research value, such value is clearly verifiable when for it are underlined specific qualifications in base to genetic peculiarity, to particular operational developments, to exemplary modes of production, to evident cultural, social, economic and environmen- tal effects. Within the various components of the design introduced recently by the CUN (National University Council), the reference of technological design to the problem solving field, in which it is possible to organize decision-making abilities and manage information for the project success, refers to the knowledge fields and to the activities that interact with the know-how, with the method and with the simultaneity of theoretical and prac- tical knowledge.

description: X-ray photoelectron spectra provide a wealth of information on the electronic structure. The extraction of molecular details requires adequate theoretical methods, which in case of transition metal complexes has to account for effects due to the multi-configurational and spin-mixed nature of the many-electron wave function. Here, the Restricted Active Space Self-Consistent Field method including spin-orbit coupling is used to cope with this challenge and to calculate valence and core photoelectron spectra. The intensities are estimated within the frameworks of the Dyson orbital formalism and the sudden approximation. Thereby, we utilize an efficient computational algorithm that is based on a biorthonormal basis transformation. The approach is applied to the valence photoionization of the gas phase water molecule and to the core ionization spectrum of the $\text{[Fe(H}_2\text{O)}_6\text{]}^{2+}$ complex. The results show good agreement with the experimental data obtained in this work, whereas the sudden approximation demonstrates distinct deviations from experiments.

description: This paper is a continuation of our Dwork crystals series. Here we exploit the Cartier operation to prove supercongruences for expansion coefficients of rational functions. In the process it appears that excellent Frobenius lifts are a driving force behind supercongruences. Originally introduced by Dwork, these excellent lifts have occurred rather infrequently in the literature, and only in the context of families of elliptic curves and abelian varieties. In the final sections of this paper we present a list of examples that occur in the case of families of Calabi-Yau varieties.

title: Advancing liquid MALDI ion source designs and applications in modern biological mass spectrometry
Creators: name: Krenkel, Henriette
Publisher: name: University of Reading
Year: 2024

description: Mass spectrometry (MS) is a sensitive and specific analytical method often used for
biological samples and assays. Its widespread application for screening is restrained by
the limited sample throughput compared to traditional photometric assay readouts. In
this work, the suitability of mass spectrometry using liquid atmospheric pressure matrix-assisted laser desorption/ionisation (LAP-MALDI) as an ionisation technique for high
speed MS analysis and screening of biochemical assays was investigated.
In a first step, a substrate and product of an enzymatic assay were detected at 5 samples/s without prior sample clean-up. More complex samples (milk) were analysed at
1 samples/s. After further improvements in hardware and software, the analysis of a
second enzymatic assay was accelerated to 16 samples/s and peptide standards were
analysed at 40 samples/s. This is faster than other MS-based methods reported in the
literature and also highly competitive with photometric readouts.
Additionally, a systematic study of various components often used in biochemical screening assays and generally biological mass spectrometry on the ion signal of a peptide
mixture was carried out. Although pronounced ion suppression was observed with some
additives, compounds such as the surfactant octyl-β-D-glucopyranoside and the buffer
tricine were found suitable with LAP-MALDI MS analysis.
In summary, LAP-MALDI allows for rapid MS sample analysis, the fast readout of
biochemical assays and shows great potential for high-throughput screening. Possible
improvements by enhanced automation are also discussed.

description: We analyze 134 ks Chandra ACIS-I observations of the Galactic Centre (GC) performed in July 2011. The X-ray image with the field of view $17' \times 17'$ contains the hot plasma surrounding the Sgr~A*. The obtained surface brightness map allow us to fit Bondi hot accretion flow to the innermost hot plasma around the GC. We have fitted spectra from region up to $5"$ from Sgr~A* using a thermal bremsstrahlung model and four Gaussian profiles responsible for K$_α$ emission lines of Fe, S, Ar, and Ca. The X-ray surface brightness profile up to $3"$ from Sgr~A* found in our data image, was successfully fitted with the dynamical model of Bondi spherical accretion. By modelling the surface brightness profile, we derived the temperature and number density profiles in the vicinity of the black hole. The best fitted model of spherical Bondi accretion shows that this type of flow works only up to $3"$ and implies outer plasma density and temperature to be: $n_{\rm e}^{\rm out}=18.3 \pm {0.1}$ cm$^{-3}$ and $T_{\rm e}^{\rm out}= 3.5 \pm {0.3}$ keV respectively. We show that the Bondi flow can reproduce observed surface brightness profile up to $3"$ from Sgr~A* in the Galactic Center. This result strongly suggests the position of stagnation radius in the complicated dynamics around GC. The Faraday rotation computed from our model towards the pulsar PSR J1745-2900 near the GC agrees with the observed one, recently reported.

description: Abstract
                Background
                Few children consume sufficient servings of fruits and vegetables. Interventions aiming to improve children’s dietary intake often target parent level factors, but limited research has examined the mediating role of parental factors on children’s dietary intake. This study examined 10-month follow up data from the Entre Familia: Reflejos de Salud (Within the Family: Reflections of Health) trial to investigate (1) intervention effects on children’s dietary intake, both sustained and new changes, and (2) whether changes in mothers’ dietary intake, her parenting strategies, and behavioral strategies to promoting healthy eating in the home mediated changes in children’s dietary intake.
                Methods
                Participants were 361 Mexican-origin families living in Imperial County, California. Families were randomly assigned to a 4-month dietary intervention or a delayed treatment control group. The intervention was delivered by promotoras (community health workers) via home visits and telephone calls. Assessments occurred at baseline, and 4- and 10-months post-baseline.
                Results
                At 10-months post-baseline, sustained intervention effects were observed on children’s reported intake of varieties of vegetables, with differences getting larger over time. However, differential intervention effects on fast food were not sustained due to significant reductions in the control group compared with smaller changes in the intervention group. New intervention effects were observed on servings of sugar-sweetened beverages. However, the intervention continued to have no effect on children’s reported fruit and vegetable servings, and varieties of fruits consumed. Mother-reported behavioral strategies to increase fiber and lower fat mediated the relationship between the intervention and children’s intake of varieties of vegetables. Mothers’ percent energy from fat and behavioral strategies to lower fat were mediators of children’s daily servings of sugar-sweetened beverages.
                Conclusions
                This study suggests that a promotora-led family based intervention can provide mothers with skills to promote modest changes in children’s diet. Examining the parent related mechanisms of change will inform future interventions on important targets for improving children’s diet.

description: Rebel victors of civil war face existential threats both internally and externally. In consolidating territorial control, how do rebel victors respond to domestic armed challengers? Do such decisions determine civil war recurrence? This paper argues that rebel victors can manage domestic risk and consolidate state power by either repressing or coopting challengers. Cooption strategies can range from the less inclusive, such as unilateral changes to the constitution and elite power-sharing arrangements, to the more inclusive, such as signing peace agreements and negotiated constitutional reform. While repression and non-inclusive cooption strategies increase chances of civil recurrence, consensus-based strategies of state consolidation, such as negotiated constitutional reform, reduce repeat civil wars. Evidence is found for our argument in newly configured data on cases of rebel victory since the end of the Cold War (1989–2015).

description: The soybean aphid, Aphis glycines (Hemiptera: Aphididae), is an invasive pest that can cause severe yield loss to soybeans in the northcentral United States. A tactic to counter this pest is the use of aphid-resistant soybean varieties. However, the occurrence of virulent biotypes can alter plant physiology and impair the use of this management strategy. Soybean aphids can alter soybean physiology primarily by two mechanisms, feeding facilitation and the obviation of resistance, favoring subsequent colonization by additional conspecifics. We developed a non-local, differential equation population model, to explore the dynamics of these biological mechanisms on soybean plants co-infested with virulent and avirulent aphids. We then use demographic parameters from laboratory experiments to perform numerical simulations via the model. These simulations successfully mimic various aphid dynamics observed in the field. Our model showed an increase in colonization of virulent aphids increases the likelihood that aphid-resistance is suppressed, subsequently increasing the survival of avirulent aphids, producing an indirect, positive interaction between the biotypes. These results suggest the potential for a "within plant" refuge that could contribute to the sustainable use of aphid resistant soybeans.

description: Background: HIV-1 Nef is a multifunctional protein required for full pathogenicity of the virus. As Nef has no
known enzymatic activity, it necessarily functions through protein-protein interaction interfaces. A critical Nef
protein interaction interface is centered on its polyproline segment (P69VRPQVPLRP78) which contains the helical
SH3 domain binding protein motif, PXXPXR. We hypothesized that any Nef-SH3 domain interactions would be lost
upon mutation of the prolines or arginine of PXXPXR. Further, mutation of the non-motif “X” residues, (Q73, V74,
and L75) would give altered patterns of inhibition for different Nef/SH3 domain protein interactions.
Results: We found that mutations of either of the prolines or the arginine of PXXPXR are defective for Nef-Hck
binding, Nef/activated PAK2 complex formation and enhancement of virion infectivity (EVI). Mutation of the
non-motif “X” residues (Q, V and L) gave similar patterns of inhibition for Nef/activated PAK2 complex formation
and EVI which were distinct from the pattern for Hck binding. These results implicate an SH3 domain containing
protein other than Hck for Nef/activated PAK2 complex formation and EVI. We have also mutated Nef residues at
the N-and C-terminal ends of the polyproline segment to explore interactions outside of PXXPXR. We discovered a
new locus GFP/F (G67, F68, P69 and F90) that is required for Nef/activated PAK2 complex formation and EVI.
MHC Class I (MHCI) downregulation was only partially inhibited by mutating the PXXPXR motif residues, but was
fully inhibited by mutating the C-terminal P78. Further, we observed that MHCI downregulation strictly requires G67
and F68. Our mutational analysis confirms the recently reported structure of the complex between Nef, AP-1 μ1 and
the cytoplasmic tail of MHCI, but does not support involvement of an SH3 domain protein in MHCI
downregulation.
Conclusion: Nef has evolved to be dependent on interactions with multiple SH3 domain proteins. To the N- and
C- terminal sides of the polyproline helix are multifunctional protein interaction sites. The polyproline segment is
also adapted to downregulate MHCI with a non-canonical binding surface. Our results demonstrate that Nef
polyproline helix is highly adapted to directly interact with multiple host cell proteins.

description: We prove a big monodromy result for a smooth family of complex algebraic surfaces of general type, with invariants p_g=q=1 and K^2=3, that has been introduced by Catanese and Ciliberto. This is accomplished via a careful study of degenerations. As corollaries, when a surface in this family is defined over a finitely generated extension of Q, we verify the semisimplicity and Tate conjectures for the Galois representation on the middle \ell-adic cohomology of the surface.

description: Two-spirit, lesbian, gay, bisexual, transgender, queer, and questioning (2SLGBTQ+) youth are overrepresented among youth experiencing homelessness and constitute 20-40% of the homeless youth population in North America. 2SLGBTQ+ youth experiencing homelessness are an understudied population and little is known about their needs or the facilitators and barriers for accessing support services and housing programs. The objective of this review is to systematically map a broad range of information on 2SLGBTQ+ youth homelessness, including what is currently known about 2SLGBTQ+ youth homelessness globally and to identify gaps in literature that could inform future research. This review will expand our understanding of 2SLGBTQ+ youth homelessness and inform policy and service delivery.

description: As the bit rates of routed data streams exceed the throughput of single wavelength-division multiplexing channels, spectral traffic aggregation becomes essential for optical network scaling. Here we propose a scheme for all-optical aggregation of several low bitrate channels to fewer channels with higher spectral efficiency. The method is based on optical vector summation facilitated by coherent spectral superposition. Thereby it does not need any optical nonlinearities and is based on linear signal processing with an electro-optic modulator. Furthermore, optical phase tuning required for vector addition can be easily achieved by a phase tuning of the radio frequency signal driving the modulator. We experimentally demonstrate the aggregation of two 10 Gbaud BPSK signals into one 10 Gbaud QPSK and one 10 Gbaud PAM-4 signal, the aggregation of two 10 Gbaud QPSK signals into 10 Gbaud QAM-16, as well as the aggregation of sinc-shaped Nyquist signals. The presented concept of in-line all-optical aggregation demonstrates considerable improvement in network spectrum utilization and can significantly enhance the operational capacity with reduced complexity. It provides a new way for realizing the flexible optical transmission of advanced modulation format signals, and suits for future dynamically reconfigurable optical networks. Since the method is based on linear signal processing with electro-optic modulator, integration into any integrated photonic platform is straightforward.
Operads in Unstable Global Homotopy Theory

description: We study operads in unstable global homotopy theory, which is the homotopy theory of spaces with compatible actions by all compact Lie groups. We show that the theory of these operads works remarkably well, as for example it is possible to give a model structure for the category of algebras over any such operad. We define global $E_\infty$-operads, a good generalization of $E_\infty$-operads to the global setting, and we give a rectification result for algebras over them.

description: In this paper, we introduce a structure-based neural network architecture, namely RC-Struct, for MIMO-OFDM symbol detection. The RC-Struct exploits the temporal structure of the MIMO-OFDM signals through reservoir computing (RC). A binary classifier leverages the repetitive constellation structure in the system to perform multi-class detection. The incorporation of RC allows the RC-Struct to be learned in a purely online fashion with extremely limited pilot symbols in each OFDM subframe. The binary classifier enables the efficient utilization of the precious online training symbols and allows an easy extension to high-order modulations without a substantial increase in complexity. Experiments show that the introduced RC-Struct outperforms both the conventional model-based symbol detection approaches and the state-of-the-art learning-based strategies in terms of bit error rate (BER). The advantages of RC-Struct over existing methods become more significant when rank and link adaptation are adopted. The introduced RC-Struct sheds light on combining communication domain knowledge and learning-based receive processing for 5G/5G-Advanced and Beyond.

description: We consider an information update system consisting of $N$ sources sending status packets at random instances according to a Poisson process to a remote monitor through a single server. We assume a heteregeneous server with exponentially distributed service times which is equipped with a waiting room holding the freshest packet from each source referred to as Single Buffer Per-Source Queueing (SBPSQ). The sources are assumed to be equally important, i.e., non-weighted average AoI is used as the information freshness metric, and subsequently two symmetric scheduling policies are studied in this paper, namely First Source First Serve (FSFS) and the Earliest Served First Serve (ESFS) policies, the latter policy being proposed the first time in the current paper to the best of our knowledge. By employing the theory of Markov Fluid Queues (MFQ), an analytical model is proposed to obtain the exact distribution of the Age of Information (AoI) for each source when the FSFS and ESFS policies are employed at the server. Subsequently, a benchmark scheduling-free scheme named as Single Buffer with Replacement (SBR) that uses a single one-packet buffer shared by all sources is also studied with a similar but less complex analytical model. We comparatively study the performance of the three schemes through numerical examples and show that the proposed ESFS policy outperforms the other two schemes in terms of the average AoI and the age violation probability averaged across all sources, in a scenario of sources possessing different traffic intensities but sharing a common service time.

description: Calcium silicate hydrates (C-S-H), the main components of hydrated cement, are known for being responsible of its cohesion. In this respect, they act as "glue" for the other solid components of mortar or concrete and thus strongly influence the mechanical properties of the outcoming material. Given the scarce knowledge about the influence of polymers on the growth and nucleation of C-S-H, this work focuses on the investigation of ongoing processes in the pre- and postnucleation stage of C-S-H precipitation. With the help of titration in combination with ion selective electrodes, effects of additives on the formation of C-S-H can be monitored and quantified resulting in new insights into the C-S-H formation in the presence of additives. Thus, this work can be regarded as a step towards a facilitated design of tailor-made C-S-H, which might result in superior cementitious materials on the long term.
