Preaspiration in Sienese Italian & Its Interaction with Stress in /VC:/ Sequences

This paper reports some initial results from our investigation into effects of stress in /VC:/ sequences in Sienese Italian. Our spontaneous speech data show preaspiration in /VC:/ sequences, not previously reported for any variety of Italian. We investigate preaspiration in /VC:/ sequences, and more specifically whether it should be considered a correlate of stress in Sienese Italian, as has been suggested for other languages. In addition we investigate how preaspiration interacts with vowel type, and vowel and consonant duration. We then seek to explain the patterns uncovered

Ghost Connect-Net: A Connectivity-Based Companion Network to Enhance Pruning Methods

Deep neural network (DNN) approaches excel in various real-world applications like robotics and computer vision, yet their computational demands and memory requirements hinder usability on advanced devices. Also, larger models heighten overparameterization risks, making networks more vulnerable to input disturbances. Recent studies aim to boost DNN efficiency by trimming redundant neurons or filters based on task relevance. Instead of introducing a new pruning method, this project aims to enhance existing techniques by introducing a companion network, Ghost Connect-Net (GC-Net), to monitor the connections in the original network. The initial weights of GC- Net are equal to the connectivity measurements of the consecutive layers in the original network. Once the connectivity-weights in GC-Net have been created and loaded, a pruning method is then applied to GC-Net. The pruned weights are mapped back to the original network determining pruned connections. This method allows for the combination of both magnitude and connectivity based pruning methods by applying magnitude based pruning approaches to the connectivity-weight values of GC-Net. Experimental results using the CIFAR-10 dataset and common CNN architectures, ResNet-18 and VGG16, show promising results for hybridizing the method, and using GC-Net for later layers of a network and direct pruning on earlier layers

A search for star-forming galaxies at high redshift

This thesis describes the first search for star formation in primeval galaxies (PGs) at redshifts z ≥ 7. Our method was to undertake deep near- infrared imaging in the J window (~ 1.0 - 1.5μm) using four narrowband filters of 2% FWHM. Over an area of sky of 3.0□¹, no emission line object was found to a sensitivity limit of ≈10⁻¹⁸ Wm⁻². Interpreting this limit in terms of a limit on Lya emission, it has been possible to place the first constraints on star formation at redshifts 7 ≤ z ≤ 9. The search is also sensitive to other emission lines at lower redshifts, of particular interest are the constraints placed on Hα emission. This line is a direct tracer of star formation (Kennicutt et al., 1987) and, at the wavelengths of the narrowband filters, it probes redshifts 0.5 ≤ z ≤ 0.9. Constraints on the star formation rate at these redshifts are of great interest in the interpretation of the excess of faint blue objects seen in number counts (Tyson 1988, Lilly et al. 1991, Metcalfe et al. 1991, Jones et al., 1991).By assuming that there is no evolution in the comoving number density of galaxies out to z = 9, and that the luminosity function of objects at these redshifts can be represented by a Schechter function, it is possible to use the limits of the IRCAM search to place constraints on the characteristic Lya luminosity L*(Lyα) of PGs. Two extremes for the bright phase Δtbright of each galaxy are considered. In Case 1, Δtbright spans the four narrowband filters (~10⁸ years). In Case 2, the bright period is much shorter, and the specific case of the Partridge & Peebles (1966) model is considered (Atbright = 3 x 10⁷ years). The 95% confidence limits for Case 1 models constrain L*(Lyα) to less than 1.6 x 10³⁷ W - 4.2 x 10³⁷ W, depending on the cosmological model. These limits are consistent with the Case 1 predictions for Lyα luminosity. For the model of Partridge & Peebles (Case 2), the predicted PG luminosity is L*(Lyα) = 2 x 10³⁸ W. Assuming that at least some galaxies are in their luminous phase in each filter then, for high values of H□, this luminosity is inconsistent with the IRCAM limits. For Ho = 75kms- 1Mpc -1, luminosities greater than r 1 x 10³⁸W are ruled out at the 95% confidence level. For low values of H₀ however, the predicted PG luminosity is consistent with the limits. Greater areal coverage would enable the models to be more severely constrained, particularly as the effects of dust would further weaken the constraints.Using the Hα limits it is possible to constrain star formation rates in the merging model of Broadhurst et al. (1992). Assuming a constant star formation rate over the redshift range 0.52 ≤ z ≤ 0.92 then, for their best fit model, characteristic star formation rates greater than 12 M⨀ yr⁻¹ (q₀ = 0.5, h₅₀ = 1.0) can be ruled out at the 95% confidence level. This constraint tightens for lower values of qo and for higher values of H₀. These are very powerful constraints, since the local star formation rate is typically 3 -10 M⨀ yr⁻¹ for normal spirals, rising to 20 M⨀ yr⁻¹ in the more active spiral galaxies. If galaxy formation follows a merging scenario to z = 0.9 then the galaxies at these redshifts cannot be forming stars at a rate any greater than that observed locally

Women Family Members’ Experiences of Involvement in Adult Inpatient Traumatic Brain Injury Rehabilitation

Background: Traumatic Brain Injury (TBI) rehabilitation is an intensive process aimed at reducing disability. The experience of care is lived not only by the patient with TBI, but by the family as well. Methods: Five women family members of patients with TBI were interviewed. Based on a descriptive qualitative approach informed by phenomenology, thematic analysis was completed to draw a general sense of family members’ description of their involvement. Results: Two themes were identified: Wearing different hats and a balancing act, that highlight the many roles undertaken by the women family members as well as the difficulties they encountered. Conclusion: Occupational therapists may assist the health care team in an attempt to identify strategies to lessen the burden on the family

L'impératif en français et en anglais contemporains

As a deontic mode of enunciation, the imperative excludes any operation which implies a certain degree of agreement between speaker and addressee - presupposition, referential construction, etc. In order to make up for this fundamental disjunction, the speaker resorts to a range of compensatory devices such as the use of person desinences, the ethical dative, the position of clitic pronouns or the function of the first person plural. Yet an imperative utterance is also related to the declarative context in which it occurs, and this sometimes causes co-locution to give way to co-enunciation - witness the problem of negative imperatives, or markers of discourse consistency such as voyons in French. This twofold theoretical approach is here presented as applying to the French language, and then put to the test of the English language

Sustainable MSD prevention: Management for continuous improvement between prevention and production. Ergonomic intervention in two assembly line companies

International audienceTo increase output and meet customers' needs, companies have turned to the development of production management systems: Kaizen, one piece flow, Kanban, etc. The aim of such systems is to accelerate decisions, react to environmental issues and manage various productions. In the main, this type of management system has led to the continuous improvement of production performance. Consequently, such production management systems can have unexpected negative effects on operators' health and safety. Conversely, regulation and control systems focusing on work-related risks have obliged firms to implement health and safety management systems such as OHSAS 18001. The purpose of this type of system, also based on continuous improvement, is to reduce risks, facilitate work-related activities and identify solutions in terms of equipment and tools. However, the prevention actions introduced through health and safety systems often result in other unexpected and unwanted effects on production. This paper shows how companies can improve the way they are run by taking into account both types of management system

Diel rhythmicity in amino acid uptake by Prochlorococcus

The marine cyanobacterium Prochlorococcus, the most abundant phototrophic organism on Earth, numerically dominates the phytoplankton in nitrogen (N)-depleted oceanic gyres. Alongside inorganic N sources such as nitrite and ammonium, natural populations of this genus also acquire organic N, specifically amino acids. Here, we investigated using isotopic tracer and flow cytometric cell sorting techniques whether amino acid uptake by Prochlorococcus is subject to a diel rhythmicity, and if so, whether this was linked to a specific cell cycle stage. We observed, in contrast to diurnally similar methionine uptake rates by Synechococcus cells, obvious diurnal rhythms in methionine uptake by Prochlorococcus cells in the tropical Atlantic. These rhythms were confirmed using reproducible cyclostat experiments with a light synchronised axenic Prochlorococcus (PCC9511 strain) culture and 35S-methionine and 3H-leucine tracers. Cells acquired the tracers at lower rates around dawn and higher rates around dusk despite >104 times higher concentration of ammonium in the medium, presumably because amino acids can be directly incorporated into protein. Leucine uptake rates by cells in the S+G2 cell cycle stage were consistently 2.2 times higher than those of cells at the G1 stage. Furthermore, S+G2 cells up-regulated amino acid uptake 3.5 times from dawn to dusk to boost protein synthesis prior to cell division. Because Prochlorococcus populations can account from 13% at midday, and up to 42% at dusk, of total microbial uptake of methionine and probably of other amino acids in N-depleted oceanic waters, this genus exerts diurnally variable, strong competitive pressure on other bacterioplankton populations
