Published: August 2024

Natural ventilation can be a suitable alternative to mechanical ventilation as it is cost-effective and environmentally friendly. Therefore, an effective design of the natural ventilation system is very crucial. In this work, an attempt has been made to investigate the impact of opening positions and roof pitch on the performance of wind-induced cross-ventilation in a gable roof building. Numerical simulations were carried out using the computational fluid dynamics (CFD) technique based on the steady Reynolds averaged Navier-Stokes equations (RANS) model. Six configurations with asymmetric openings on opposite facades were considered to evaluate the effect of opening positions. Further, for studying the influence of roof pitch on the flow properties, three roof pitches, viz. 3:10, 5:10 and 7.5:10 were considered. It is found that the configuration with a windward opening in the middle and a leeward opening at the bottom (Configuration D) has the highest flow rate. The configuration with a windward opening at the top and a leeward opening at the bottom (Configuration B) has the lowest flow rate. Furthermore, the investigation with different roof pitches reveals that buildings with lower roof pitches are more vulnerable to wind loading due to higher flow separation at the windward eave. The investigation concludes that the opening position and roof pitch significantly influences the indoor airflow characteristics thereby affecting the ventilation performance.

A ring frame is a machine used for yarn production in the textile industry. Continuous use of the machine results in wear on the shaft timing pulley on the ring frame machine. To improve this condition, repairs are needed, one of which uses the hardfacing method. This study aims to determine the effect of hardfacing on the microstructure and hardness of the shaft timing pulley made from AISI 1045. The hardfacing process used the shielded metal arc welding (SMAW) method with welding current variations of 115 A, 125 A, 135 A, 145 A, and 155 A. In this study, the electrode used was AWS A5.1 E7018 with a diameter of 3.2 mm. The hardfacing product obtained was then finished with a lathe to produce a shaft with a final diameter of 30 mm. In this study, microstructure and hardness tests were carried out on specimens before and after finishing. The results of this study showed that an increase in current caused an increase in the number of pearlite phases in the weld metal and HAZ (heat-affected zone) areas. While in the base metal, the increase in current increased the number of ferrite phases. The highest hardness value was found in specimens that were hardfaced with a current of 145 A. However, the hardness of the hardfacing layer will decrease with the use of currents greater than 145 A. The hardness of the specimens with hardfacing treatment at a current of 145 A resulted in hardness in the weld metal, HAZ, and base metal of 225 HV, 209 HV, and 203 HV, respectively. After the finishing process, the weld metal, HAZ, and base metal in this specimen produced a hardness of 225 HV, 217 HV, and 208 HV, respectively.

The widespread method of relative phase modulation has disadvantages compared to absolute phase modulation: the need to transmit a pilot signal at the beginning of a communication session, less noise immunity, and more complex hardware implementation. In addition, during a random jump, not only the current symbol is distorted, but also the next one. And correcting a double error requires the use of a correcting code with greater correcting ability. However, absolute phase modulation, despite its advantages, is almost never used due to switching to the “reverse operation” mode when the phase of the reference signal jumps. A solution to the problem of using absolute modulation is provided by considering the phenomenon of “backward work” in terms of error-correcting coding, from the point of view of which “backward work” is a set of burst errors, the number of which can reach 100% of the length of the transmitted code word. For most error-correcting codes, correcting more than 50% of burst errors is an impossible task, but the holographic positional code gives the same decoding result for both the forward and inverted data blocks. A soft holographic code decoder is described that provides error-free decoding of a signal with absolute phase modulation without using a reference signal with phase jumps up to two times during the reception of one data block.

Evaluating Kolmogorov–Arnold Networks for Scientific Discovery: A Simple Yet Effective Approach
Authors: Sun Josh Qixuan
Published: August 2024

Kolmogorov–Arnold Network (KAN) is an emerging interpretable neural network compared to fully black-box MLPs. Recently, emerging works focus on comprehensive and fair comparisons between KAN and MLP in various tasks. However, these works didn't focus on the strongest advantage of KAN: generating symbolic outputs. The ability of KAN to provide scientific insights or even discover new science is under-examined.In this work, we propose several novel metrics to measure how well a KAN performs on symbolic function fitting: R^2-Mean, weighted R^2-complexity loss, and ranking metrics. We also propose a metric to determine mathematical complexity of a target function and evaluate KAN with several functions of different mathematical complexity.Additionally, we also tried inputs with different ranges to find the effect of normalization.
The turbulent dynamics of anticyclonic submesoscale headland wakes
Authors: Chor Tomas , Wenegrat Jacob
Published: August 2024

Flow interacting with bathymetry has been posited to be important for dissipation and mixing in the global ocean. Despite this, there are large uncertainties regarding mixing in these environments, particularly as it pertains to the role of submesoscale structures in the dynamics and energetics. In this work we study such flows with a series of Large-Eddy simulations of a submesoscale flow past a headland where the turbulence is resolved, allowing us to probe into the small-scale processes responsible for the energy cascade. One key finding is that the kinetic energy (KE) dissipation rate, buoyancy mixing rate, and eddy diffusivity of the flow organize as linear functions of the bulk Rossby and Froude numbers across all simulations, despite very different dynamical regimes. The slope Burger number (Rossby over Froude number) was found to be particularly useful as it can organize aspects of both the dynamics and energetics. Moreover, comparison of KE dissipation rates with previous works suggests an underestimation of dissipation rates by regional models of up to an order of magnitude, with potential implications for global energy budgets. Consistent with hypotheses from previous studies, but resolved here for the first time up to small scales, we find evidence of submesoscale centrifugal-symmetric instabilities (CSIs) in the wake leading to a forward energy cascade. However, given that dissipation and mixing rates seem to follow the same scaling across regimes with and without CSIs, their effect on flow energetics here differs from what has been observed in the upper ocean, where CSI turbulence seems to follow a different scaling from their non-CSI counterparts.
How Consumer Lay Theories Shape Valuation of AI Creativity
Authors: Caprioli Sara , Granulo Armin , Castelo Noah
Published: August 2024

Recent advances in artificial intelligence (AI) have empowered algorithms to produce creative content across various domains, including artistic fields such as music and design, and scientific fields such as biology and chemistry. Despite these advancements, consumers remain skeptical about AI’s role in creative tasks. This research proposes that consumers’ aversion to the use of AI for creative tasks is rooted partly in misconceptions about the nature of creativity itself. According to the dual-path model of creativity, creativity involves two critical pathways: flexibility and persistence. We show that consumers often undervalue the persistence path (e.g., systematic exploration) compared to the flexibility path (e.g., distal associations). Since consumers believe that AI can excel at tasks requiring persistence but not at tasks requiring flexibility, they undervalue AI-generated creative output. We show however that highlighting the persistence path increases consumer acceptance of AI and human-AI collaboration in creative tasks. Through six experimental studies (N = 880), this research informs the consumer psychology of AI creativity, helping firms understand when AI use enhances or diminishes value in consumers’ eyes.

Published: August 2024

Background: Cognitively able autistic adults demonstrate low rates of employment due to social and vocational challenges. The current study aimed to examine changes in various areas among autistic young adults who participated in the 'Roim Rachok' ('Looking Ahead' in Hebrew) Training Course (RRTC). The course prepares young autistic adults for integration into military service as vocational soldiers. Methods: The study included 49 autistic participants who completed the RRTC in one of three vocational fields: Digital (n = 19), Technical (n = 9), and Visual (n = 21). Evaluations at the beginning and end of the course included adaptive behavior (Adaptive Behavior Assessment Scale 2nd Edition [ABAS-II]), autism symptom severity (Social Responsiveness Scale 2nd Edition [SRS-II]), and communication skills (Faux Pas; Empathy Quotient [EQ]; Friendship Quality Scale; Conversation task based on Yale in vivo Pragmatic Protocol [YiPP]).Results: The results revealed a significant Time effect for the self-reported ABAS-II conceptual, social, and practical subdomains, EQ empathy quotient subdomain, Faux Pas, and SRS-II social communication interaction scores. Accordingly, participants reported increasing their adaptive skills, emotional empathy, and the ability to detect and interpret awkward statements, and decreased in their social communication interaction symptoms, following the RRTC. No significant Time x Group interaction was found for any of the examined measures, meaning similar trends were observed in all three vocational groups. Conclusion: Following the RRTC, participants reported significant improvements in areas essential for their future integration as soldiers in the military and as employees in the vocational world. Implications of the study findings are discussed.

Most people with mental health needs cannot access treatment; among those who do, many access services only once. Accordingly, single-session interventions (SSIs) may help bridge the treatment gap. We conducted the first umbrella review synthesizing research on SSIs for mental health problems and service engagement in youth and adults. Our search yielded 24 systematic reviews of SSIs including 415 unique trials. Twenty reviews (83.33%) reported significant, positive effects of SSIs for >1 outcomes (anxiety; depression; externalizing problems; eating problems; substance use; treatment engagement or uptake). Across 12 reviews that meta-analytically examined SSIs’ effectiveness relative to controls, SSIs showed a positive effect across outcomes and age groups, SMD=-0.25, I2 = 43.17%. Per AMSTAR-2, some methodological concerns emerged across reviews, such low rates of pre-registration. Overall, findings support the clinical utility of SSIs for certain psychological problems and populations. Implementation research is needed to integrate effective SSIs into systems of care.

Published: August 2024

The demographic explosion of Algerian cities by a positive natural balance and population migration movements transforms urban landscapes and leads them to growing environmental pressure.
The resulting spatial increase is more or less planned. It does not only characterize large cities or capitals. The so-called medium-sized cities are also affected, if not more, because they rarely have the assets of large cities to exercise planning and control.
The growth of these urban centers has several effects: densification of the fabric, change of urban areas preserved or associated with specific functions, and progress towards agricultural or natural areas.
Because it leads to increasing needs for housing and services, growth is reflected in the anarchic extension of the urban area on one hand, and in the appearance of unprompted urban houses on the surroundings of cities.
Based on the general hypothesis that urban spatial forms can be analysed using available and supposedly reliable divisions, we attempted to analyse some divisions of Khenchela Province. Our analysis focused on identifying the forms that favour the indications (organizations, directions, temporality, etc.) they provide and the constitution of forms of these divisions.
The objectives of the delimitation of urbanization zones (sectors, districts, boroughs) aim to ensure the achievement of the spatial planning orientations from which the objectives are significant. Spatial organization must contribute to the quality of life of the inhabitants, including future generations. (Christophe, 1998)
The reaction concerning the organization of the different functions (housing, economic activities, shops, leisure facilities, transport infrastructures, etc.) indeed affects everyone's living environment. It can have considerable consequences in many areas directly related to Khenchela Province inhabitants.

The article presents a new regional mechanism for supporting and developing local production - local production development areas, which will operate on the territory of the Republic of Sakha (Yakutia). These territories are territories of preferential treatment, such as special economic zones and priority social and economic development area. They can be created on the territory of one or several settlements within one municipal district. Residence in these territories allows you to apply for benefits on regional and local taxes, reimbursement of part of the costs of paying insurance contributions to state extra-budgetary funds and other types of government support provided at the federal, regional and municipal levels. Local production development areas will be provided with state support in the creation and modernization of infrastructure facilities, in the form of capital investments in transport, energy, and engineering infrastructure. The decision to create territories is approved by a decree of the regional government. The first resolutions on the creation of such territories were adopted at the end of 2023. According to the research, the next areas where preferential regime territories can be created are the areas of the Zarechnaya agricultural zone of the republic, which includes 5 uluses (districts). In the Arctic zone of Yakutia, a pilot territory can be created in the Verkhoyansk ulus.

Addressing Patron’s Increasing Psychosocial Needs in the Public Library: Responsive Community Care Through Improved Education, Training, and Partnerships
Authors: Sebastiano Jessica
Published: August 2024

The public library remains perhaps the only truly free public space, one that vulnerable community members can easily and safely access. Consequently, public libraries’ physical spaces are being used to meet patrons’ complex physical, psychological, and social needs. Public library staff are increasingly encountering patrons experiencing mental health issues, housing precarity, and substance use issues (such as opioid poisoning and overdoses), as well as a rise in security incidents. Unfortunately, public library staff are often not adequately trained to navigate these challenging situations before encountering them. As front-line workers, public library staff must be supported by library organizations and institutions to provide the best service for their patrons and protect themselves from burnout, traumatization, and compassion fatigue. This must include clear, consistent policies and procedures and appropriate training that support staff’s physical and mental health. Creating more social work-aligned programs in Library and Information Science (LIS) education, partnering with community organizations to address gaps in service and knowledge, and introducing trauma-informed practices to the public library would work to empower and protect staff and strengthen equitable library service.

OBJECTIVE

In 10% of patients undergoing carotid endarterectomy (CEA), the cognitive function declines postoperatively, primarily in association with postoperative cerebral hyperperfusion. In contrast, in the majority of patients undergoing CEA, long-term cognitive outcomes remain unclear. Furthermore, it is not known whether the decline in cognition due to cerebral hyperperfusion recovers on a long-term basis. This study aimed to understand how postoperative cerebral hyperperfusion affects the cognitive outcomes of patients who undergo CEA.

METHODS

The participants in this prospective observational study were patients with internal carotid artery stenosis who underwent CEA. Cerebral hyperperfusion syndrome or asymptomatic cerebral hyperperfusion following CEA was determined based on brain perfusion SPECT scans and symptomatology before and after surgery. Neuropsychological testing was performed preoperatively, at 1–2 months postoperatively, and at 2 years postoperatively to investigate cognitive decline.

RESULTS

A logistic regression analysis revealed that asymptomatic cerebral hyperperfusion (95% CI 13.0–84.5, p < 0.0001) and cerebral hyperperfusion syndrome (95% CI 449.7–14,237.4, p < 0.0001) were significantly associated with cognitive decline at 1–2 months postoperatively. The incidence of cognitive decline was significantly decreased at 2 years postoperatively (7%) in comparison to 1–2 months postoperatively (11%) (p = 0.0461). A logistic regression analysis also revealed that asymptomatic cerebral hyperperfusion (95% CI 3.7–36.7, p < 0.0001), cerebral hyperperfusion syndrome (95% CI 128.0–6183.6, p < 0.0001), and further strokes during the 2-year follow-up period (95% CI 1.5–78.7, p = 0.0167) were significantly associated with cognitive decline at 2 years postoperatively. The incidence of cognitive decline at 1–2 months postoperatively was significantly higher in patients with cerebral hyperperfusion syndrome (100%) than in those with asymptomatic cerebral hyperperfusion (44%) (p < 0.0001). No significant difference in incidence was observed in the former patients at 2 years postoperatively (88%), but significant reduction was found in patients with asymptomatic cerebral hyperperfusion and cognitive decline between the timepoints of 1–2 months postoperatively (100%) and 2 years postoperatively (39%) (p = 0.0001).

CONCLUSIONS

Postoperative cerebral hyperperfusion causes prolonged cognitive decline at 2 years postoperatively in patients undergoing CEA.

OBJECTIVE

A superficial temporal artery–middle cerebral artery (STA-MCA) bypass is classically considered a low-flow bypass. It is known that the flow in the flow augmentation STA-MCA bypass is influenced by flow demand of the revascularized territory and can reach significantly higher values. The authors report their intraoperative flow measurement data in a consecutive series of 100 STA-MCA bypasses performed at their institution. Moreover, in a subanalysis, they show the postoperative bypass flow measured with quantitative MR angiography (qMRA) noninvasive optimal vessel analysis (NOVA).

METHODS

Between January 2013 and October 2023, 100 patients with acute, subacute, or chronic large-vessel occlusion (LVO) or moyamoya disease underwent a flow augmentation STA-MCA bypass revascularization at the authors’ department with intraoperative bypass flow measurement. Patients with atherosclerotic LVO who underwent bypass surgery within a 6-week period following the onset of ischemic stroke symptoms were categorized into the acute bypass group, encompassing both acute and subacute LVO cases. Conversely, those who underwent bypass surgery > 6 weeks after the last occurrence of ischemic stroke were classified as the chronic group. Since May 2019, a consecutive subgroup of 37 patients received a postoperative (before discharge) bypass flow measurement with the qMRA-NOVA imaging tool.

RESULTS

The mean ± SD intraoperative bypass flow in this consecutive series of 100 STA-MCA bypasses was 53.5 ± 28.8 ml/min (range 14–145 ml/min). In the subanalysis, there was no difference in the intraoperative flow capacity between the acute and chronic groups and between the moyamoya and acute groups. Patients in the moyamoya group showed a significantly higher flow rate in the STA-MCA bypass compared with the chronic group (63.0 ± 30.2 ml/min vs 48.4 ± 26.5 ml/min, p = 0.03). In a consecutive subanalysis of 37 STA-MCA bypass cases, postoperative flow measurements were also performed using qMRA-NOVA, showing a significant increase in the flow of STA-MCA bypasses after surgery compared with intraoperative flow measurements (mean intraoperative bypass flow rate vs qMRA-NOVA postoperative bypass flow rate: 73.4 ± 29.9 ml/min vs 111.3 ± 51.4 ml/min, p = 0.005).

CONCLUSIONS

Using intraoperative and postoperative quantitative flow measurements of the STA, the data confirm that the flow in the flow augmentation STA-MCA bypass is influenced by the flow demand of the revascularized territory and can reach high values if needed. Moreover, the significant flow increase in the postoperative flow measurement using qMRA-NOVA demonstrates that the bypass can increase its flow over time.
Optimizing indirect targeting of the centromedian nucleus for deep brain stimulation by incorporating third ventricular anatomy

OBJECTIVE

Deep brain stimulation (DBS) of the centromedian nucleus (CM) is used to treat diverse brain diseases including epilepsy, Tourette syndrome, and disorders of consciousness. However, the CM is challenging to visualize on routine MRI. Many surgeons use an indirect targeting method based on established stereotactic coordinates. The authors aimed to quantify how often a DBS electrode’s contacts were positioned within the CM using this approach, and to identify alternative indirect coordinates that are more accurate.

METHODS

Indirect targeting of the CM was performed on 100 MR images obtained in healthy adults, and the resulting coordinates were warped to a common brain template. To estimate positions of DBS contacts along this trajectory, the authors developed a probable electrode location (PEL) mask, modeled on trajectory angles obtained from prior clinical cases. Euclidean and x, y, and z distances between the centroids of the PEL mask and an atlas-based CM mask were measured and defined as error. The percentage of overlaps between the PEL mask and nearby thalamic nuclei was determined. To assess the clinical utility of this methodology, the analysis was validated using 20 MR images obtained in patients with generalized epilepsy, a common clinical indication for CM-DBS.

RESULTS

Using standard indirect coordinates, the authors found the average Euclidean error to be 4.40 ± 1.05 mm, and the x, y, and z errors were 4.19 ± 0.97 mm, 0.73 ± 0.65 mm, and 0.66 ± 0.69 mm, respectively. The PEL mask overlap was 52% with the CM and 65% with the ventral posteromedial nucleus. Variation in third ventricular width was the dominant contributor to these errors (r = −0.71). To overcome this variation, the authors developed alternative indirect coordinates: 4.5 mm lateral to the posterolateral corner of the third ventricle at the level of the posterior commissure. With this refinement, the average Euclidean error was reduced to 1.24 ± 0.5 mm, with 84% of the PEL mask within the CM.

CONCLUSIONS

The unavailability of advanced MRI for direct targeting limits access to CM-DBS in resource-constrained neurosurgical programs. Standard indirect coordinates do not provide optimal targeting of the CM, with most contacts laterally placed in the sensory thalamus. The proposed indirect approach may therefore increase the accuracy and availability of CM-DBS, while reducing side effects.
Anterior choroidal artery aneurysms: a systematic review and meta-analysis of outcomes and ischemic complications following surgical and endovascular treatment

OBJECTIVE

Anterior choroidal artery (AChA) aneurysms account for 2%–5% of all intracranial aneurysms. Treatment considerations include microsurgical clipping, flow diversion, or coiling with or without adjunctive devices. AChA aneurysms pose challenges in treatment due to the origination of the aneurysm from the origin or proximal segment of the AChA. The AChA is particularly susceptible to vasospasm and occlusion during treatment with devastating neurological deficits, including hemiparesis, hemianesthesia, lethargy, neglect, and hemianopia. In this study, the authors performed a meta-analysis to quantify the outcomes and complication rates across treatment modalities for AChA aneurysms and to identify risk factors reported in the literature.

METHODS

The authors performed a systematic review of AChA aneurysms treated with surgical clipping, endovascular coiling, or flow diversion and reported in the PubMed, Embase, Scopus, and Cochrane search databases. Single-arm meta-analyses of the selected outcomes were performed in RStudio.

RESULTS

Literature review yielded 25 studies that met the inclusion criteria. In total, 1627 patients were included in the analysis, with 554 males, 1009 females, and 64 unspecified. The rate of any complication in the full cohort was 11.6%, with a rate of ischemic complications of 5.5% and a favorable recovery rate of 90.3% of all patients treated. In total, 1064 patients underwent surgical clipping, 443 were treated with coiling, and 120 patients with flow diversion. In clipped patients, the rate of total surgical complications was 17.6%, with an ischemic complication rate of 9.4%. The rate of good functional recovery, defined on the basis of a Glasgow Outcome Scale score of 4–5 or modified Rankin Scale score of 0–2, was 88.0%, and complete obliteration was achieved in 84.5% of surgically clipped aneurysms. The complication rate in coiled patients was 10.3%, with an ischemic complication rate of 3.0%. Good functional recovery was achieved in 88.6% of coiled patients and complete aneurysm obliteration in 74.1%. Flow diversion resulted in a complication rate of 1.3%, with 0.7% rate of ischemic complications. Good functional recovery was achieved in 98.4% of patients and complete aneurysm obliteration in 79.0% in the flow diversion group. Aneurysm morphological features that impacted the complication rate were also identified to augment quantitative data and to help guide treatment selection for AChA aneurysms.

CONCLUSIONS

Flow diversion showed significantly lower total and ischemic complications and improved outcomes compared to clipping and coiling. There may be differences in outcomes between treatment types, especially when considering the varied patient presentations that guide treatment selection.
