The nuts and bolts of supersymmetric gauge theories on biaxially squashed three-spheres

We present the gravity dual to a class of three-dimensional N = 2 supersymmetric gauge theories on a biaxially squashed three-sphere, with a non-trivial background gauge field. This is described by a 1/2 BPS Euclidean solution of four-dimensional N = 2 gauged supergravity, consisting of a Taub-NUT-AdS metric with a non-trivial instanton for the graviphoton field. The holographic free energy of this solution agrees precisely with the large N limit of the free energy obtained from the localized partition function of a class of Chern-Simons quiver gauge theories. We also discuss a different supersymmetric solution, whose boundary is a biaxially squashed Lens space S 3 /Z2 with a topologically nontrivial background gauge field. This metric is of Eguchi-Hanson-AdS type, although it is not Einstein, and has a single unit of gauge field flux through the S 2 cycle.
Neural Tracking Measures of Speech Intelligibility: Manipulating Intelligibility while Keeping Acoustics Unchanged

Neural speech tracking has advanced our understanding of how our brains rapidly map an acoustic speech signal onto linguistic representations and ultimately meaning. It remains unclear, however, how speech intelligibility is related to the corresponding neural responses. Many studies addressing this question vary the level of intelligibility by manipulating the acoustic waveform, but this makes it difficult to cleanly disentangle effects of intelligibility from underlying acoustical confounds. Here, using magnetoencephalography (MEG) recordings, we study neural measures of speech intelligibility by manipulating intelligibility while keeping the acoustics strictly unchanged. Acoustically identical degraded speech stimuli (three-band noise vocoded, ∼20 s duration) are presented twice, but the second presentation is preceded by the original (non-degraded) version of the speech. This intermediate priming, which generates a ‘pop-out’ percept, substantially improves the intelligibility of the second degraded speech passage. We investigate how intelligibility and acoustical structure affects acoustic and linguistic neural representations using multivariate Temporal Response Functions (mTRFs). As expected, behavioral results confirm that perceived speech clarity is improved by priming. TRF analysis reveals that auditory (speech envelope and envelope onset) neural representations are not affected by priming, but only by the acoustics of the stimuli (bottom-up driven). Critically, our findings suggest that segmentation of sounds into words emerges with better speech intelligibility, and most strongly at the later (∼400 ms latency) word processing stage, in prefrontal cortex (PFC), in line with engagement of top-down mechanisms associated with priming. Taken together, our results show that word representations may provide some objective measures of speech comprehension. Significance Statement Electrophysiological studies have shown that brain tracks different speech features. How these neural tracking measures are modulated by speech intelligibility, however, remained elusive. Using noise-vocoded speech and a priming paradigm, we disentangled the neural effects of intelligibility from the underlying acoustical confounds. Neural intelligibility effects are analyzed at both acoustic and linguistic level using multivariate Temporal Response Functions. Here, we find evidence for an effect of intelligibility and engagement of top-down mechanisms, but only in responses to lexical structure of the stimuli, suggesting that lexical responses are strong candidates for objective measures of intelligibility. Auditory responses are not influenced by intelligibility but only by the underlying acoustic structure of the stimuli.

27 Cephalopods are emerging animal models and iconic species to study the link between genomic 28 innovations and physiological and behavioral complexities. Coleoid cephalopods possess the largest 29 nervous system among invertebrates, both for cell counts and body-to-brain ratio. Octopus vulgaris has 30 been at the center of a long-standing tradition of research into diverse aspects of cephalopod biology, 31 including behavioral and neural plasticity, learning and memory recall, regeneration
A uniform quantificational logic for algebraic notions ofcontext

A quantificational framework of formal reasoning is proposed, which emphasises the pattern of entering and exiting context. Contexts are modelled by an algebraic structure which reflects the order and manner in which context is entered into and exited from. The equations of the algebra partitions context terms into equivalence classes. A formal semantics is defined, containing models that map equivalence classes of certain context terms to sets of first order structures. The corresponding Hilbert system incorporates the algebraic equations as axioms asserted in context. In this way a uniform logic for arbitrary algebras of context is obtained. Soundness and completeness are proved. In semigroups of contexts, where combination of contexts is associative, finite ground algebraic equations correspond to contingent equivalence between certain logical formulas. Systems for sets and multisets of contexts are obtained by presenting their respective algebras as associativity plus finite ground equations. Some contextual reasoning systems in the literature are inherently associative, and we present those as special cases.
Cough Effectiveness, Functional Independence and Quality of Life of Stroke Survivors: A Cross-sectional Survey

Background: Stroke is associated with clinical spectrum of respiratory impairments, a significant one being aspiration pneumonia owing to failure to safeguard and clear the airway through coughing. Objectives: This research evaluated the correlation among cough effectiveness, functional independence, and quality of life of stroke survivors. Methods: This study involved 33 stroke survivors (13 males and 20 females) aged between 39-80 years. They were recruited from a teaching hospital in Nigeria. The participants were recruited between April and October, 2018. Cough effectiveness, functional independence (FI) and perception of quality of life (QoL) were assessed using Peak flow meter, Functional Independence Measure (FIM) and Stroke Specific Quality of Life Scale (SS-QoL) respectively. Spearman rank correlation coefficient was used to obtain the relationship between measured parameters. Level of significance was set at p<0.05. Results: The mean peak cough flow (PCF) was 195.75±51.90 L/min for all the study participants. There was a positive significant correlation between cough effectiveness and motor subunit of FIM (rs=0.530, p=0.002) and overall FIM (rs=0.484, p=0.004). There was also a positive significant correlation between cough effectiveness and overall QoL score (rs=0.517, p=0.002). Five domains of QoL showed positive significant correlation to cough effectiveness; these include Mobility (rs=0.524, p=0.002), Self-care (rs=0.448, p=0.009), Social role (rs=0.487, p=0.004), Upper-limb function (rs=0.535, p=0.001), and Work and productivity (rs=0.556, p=0.001). Conclusion: Cough effectiveness is significantly positively correlated to functional independence and the QoL of stroke survivors.
Urban–Rural Disparities in Case Fatality of Community-Acquired Sepsis in Germany: A Retrospective Cohort Study

Background: We aimed to examine urban–rural disparities in sepsis case fatality rates among patients with community-acquired sepsis in Germany. Methods: Retrospective cohort study using de-identified data of the nationwide statutory health insurance AOK, covering approx. 30% of the German population. We compared in-hospital- and 12-month case fatality between rural and urban sepsis patients. We calculated odds ratios (OR) with 95% confidence intervals and the estimated adjusted odds ratio (ORadj) using logistic regression models to account for potential differences in the distribution of age, comorbidities, and sepsis characteristics between rural and urban citizens. Results: We identified 118,893 hospitalized patients with community-acquired sepsis in 2013–2014 with direct hospital admittance. Sepsis patients from rural areas had lower in-hospital case fatality rates compared to their urban counterparts (23.7% vs. 25.5%, p < 0.001, Odds Ratio (OR) = 0.91 (95% CI 0.88, 0.94), ORadj = 0.89 (95% CI 0.86, 0.92)). Similar differences were observable for 12-month case fatalities (45.8% rural vs. 47.0% urban 12-month case fatality, p < 0.001, OR = 0.95 (95% CI 0.93, 0.98), ORadj = 0.92 (95% CI 0.89, 0.94)). Survival benefits were also observable in rural patients with severe community-acquired sepsis or patients admitted as emergencies. Rural patients of <40 years had half the odds of dying in hospital compared to urban patients in this age bracket (ORadj = 0.49 (95% CI 0.23, 0.75), p = 0.002). Conclusion: Rural residence is associated with short- and long-term survival benefits in patients with community-acquired sepsis. Further research on patient, community, and health-care system factors is needed to understand the causative mechanisms of these disparities.
Differences between Novice and Expert Raters Assessing Trunk Control Using the Trunk Control Measurement Scale Spanish Version (TCMS-S) in Children with Cerebral Palsy

The Trunk Control Measurement Scale (TCMS) is a valid and reliable tool to assess static and dynamic trunk control in cerebral palsy. However, there is no evidence informing about differences between novice and expert raters. A cross-sectional study was conducted with participants between the ages of 6 and 18 years with a CP diagnosis. The TCMS Spanish version (TCMS-S) was administered in-person by an expert rater, and video recordings were taken for later scoring by the expert and three other raters with varying levels of clinical experience. The intraclass correlation coefficient (ICC) was used to evaluate reliability between raters for the total and subscales of the TCMS-S scores. Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC) were also calculated. There was a high level of agreement between expert raters (ICC ≥ 0.93), while novice raters demonstrated good agreement (ICC > 0.72). Additionally, it was observed that novice raters had a slightly higher SEM and MDC than expert raters. The Selective Movement Control subscale exhibited slightly higher SEM and MDC values compared to the TCMS-S total and other subscales, irrespective of the rater’s level of expertise. Overall, the study showed that the TCMS-S is a reliable tool for evaluating trunk control in the Spanish pediatric population with cerebral palsy, regardless of the rater’s experience level.
“I Feel Like I Work Full-Time for Parkinson’s”: A Longitudinal Interpretative Phenomenological Analysis of the Experiences of Parkinson’s Informal Caregivers during COVID-19 in England

While the direct effects of COVID-19 caused widespread global suffering and death, the indirect impacts—via public health preventative measures and a reduction in health and social care services—were also devastating for many. More recently, it has also become increasingly apparent that such measures have had disproportionate effects, exacerbating existing health inequalities. For caregivers of individuals with chronic illness, the effects have been marked and particularly so for informal caregivers of individuals with complex neurodegenerative conditions such as Parkinson’s. Nine informal caregivers (all partners: three men and six women) of individuals with Parkinson’s in England took part in individual semi-structured interviews on two occasions (December 2021/January 2022 and May 2022). The interviews focused on their experiences of supporting their partner, their own challenges, and how these evolved and changed post-lockdown. Interpretative phenomenological analysis was used to inform the methodology and analysis. Four themes were identified: (i) lockdown-induced revolution and evolution of the relationship dynamic with partner; (ii) fighting to be seen, heard, and understood in healthcare encounters; (iii) making sense of, and adapting to, risk in a time of COVID-19; and (iv) managing isolation and need for support during and after lockdown. The negative effects from both the lockdowns and the depletion of usual health and support services were apparent for all participants. Existing vulnerabilities from being a carer of an individual with complex needs were also exacerbated. As caregivers worked hard to mitigate these effects for their partners as much as possible, the long-term impact of such intense psychological and practical effort was often considerable. Ultimately, a simple restoration of pre-lockdown support levels may be insufficient to facilitate a successful return to optimal levels of support and wellbeing.
Pharmacotherapeutic follow-up of patients on warfarin in primary care: randomized clinical trial

Aim: To evaluate the impact of pharmacotherapeutic follow-up on bleeding, time in therapeutic range (TTR), thrombotic events, general adverse events, hospitalizations, drug interactions and average number of medications used in patients taking warfarin in the Brazilian public healthcare system. Methods: A randomized clinical trial was conducted with individuals divided into two groups (intervention group [pharmacotherapeutic follow-up] and control group) who received at-home visits over an eight-month period. Results: 38individuals (21 in the intervention group and 17 in the control group) concluded the study. Fewer number of cases of bleeding was found in the group that received pharmacotherapeutic follow-up, but no significant association was found between these variables. No significant association was found between pharmacotherapeutic follow-up and TTR. The intervention group had a greater frequency in the therapeutic range for capillary INR but not for laboratory INR. Reductions were found in the intervention group with regards to general adverse events, the use of medications and drug interactions, whereas no reduction was found in hospitalizations. Conclusions: Based on the findings of the present study, pharmacotherapeutic follow-up did not exert an influence on bleeding or TTR. However, reductions were found in adverse events and drug interactions, which can contribute to the rational use of medicines and could result in lower care costs for patients requiring blood thinners
Detecting Relevant Interactions in High Dimensional Data Analysis

In high dimensional data, relevant interactions can be difficult to identify due to the extremely large number of possible interactions among variables. Conventional methods use a screening stage to vastly reduce the dimension of the variable space before examining the interaction effect. However, this type of screening relies on the assumption that the relevant variables of interactions also have significantly strong marginal effects, which may not be the case in many applications. Hence we propose a multi-stage screening method that considers interaction effects to ensure that variables with weak marginal effect can still be identified if their interactions are strong. The proposed screening method can achieve the same reduction of dimensionality in linear computational time using a random sampling scheme. Experimental studies on three simulated scenarios, a financial news dataset and a biostatistics dataset show that the proposed approach can effectively identify variables that are of weak marginal effect but relevant interaction effect.
Single-Dose Treatment with Rapamycin Preserves Post-Ischemic Cardiac Function through Attenuation of Fibrosis and Inflammation in Diabetic Rabbit

Robust activation of mTOR (mammalian target of rapamycin) signaling in diabetes exacerbates myocardial injury following lethal ischemia due to accelerated cardiomyocyte death with cardiac remodeling and inflammatory responses. We examined the effect of rapamycin (RAPA, mTOR inhibitor) on cardiac remodeling and inflammation following myocardial ischemia/reperfusion (I/R) injury in diabetic rabbits. Diabetic rabbits (DM) were subjected to 45 min of ischemia and 10 days of reperfusion by inflating/deflating a previously implanted hydraulic balloon occluder. RAPA (0.25 mg/kg, i.v.) or DMSO (vehicle) was infused 5 min before the onset of reperfusion. Post-I/R left ventricular (LV) function was assessed by echocardiography and fibrosis was evaluated by picrosirius red staining. Treatment with RAPA preserved LV ejection fraction and reduced fibrosis. Immunoblot and real-time PCR revealed that RAPA treatment inhibited several fibrosis markers (TGF-β, Galectin-3, MYH, p-SMAD). Furthermore, immunofluorescence staining revealed the attenuation of post-I/R NLRP3-inflammasome formation with RAPA treatment as shown by reduced aggregation of apoptosis speck-like protein with a caspase recruitment domain and active-form of caspase-1 in cardiomyocytes. In conclusion, our study suggests that acute reperfusion therapy with RAPA may be a viable strategy to preserve cardiac function with the alleviation of adverse post-infarct myocardial remodeling and inflammation in diabetic patients.
On the Thermomechanical Behavior of 3D-Printed Specimens of Shape Memory R-PETG

From commercial pellets of recycled polyethylene terephthalate glycol (R-PETG), 1.75 mm diameter filaments for 3D printing were produced. By varying the filament’s deposition direction between 10° and 40° to the transversal axis, parallelepiped specimens were fabricated by additive manufacturing. When bent at room temperature (RT), both the filaments and the 3D-printed specimens recovered their shape during heating, either without any constraint or while lifting a load over a certain distance. In this way, free-recovery and work-generating shape memory effects (SMEs) were developed. The former could be repeated without any visible fatigue marks for as much as 20 heating (to 90 °C)-RT cooling–bending cycles, while the latter enabled the lifting of loads over 50 times heavier than the active specimens. Tensile static failure tests revealed the superiority of the specimens printed at larger angles over those printed at 10°, since the specimens printed at 40° had tensile failure stresses and strains over 35 MPa and 8.5%, respectively. Scanning electron microscopy (SEM) fractographs displayed the structure of the successively deposited layers and a shredding tendency enhanced by the increase in the deposition angle. Differential scanning calorimetry (DSC) analysis enabled the identification of the glass transition between 67.5 and 77.3 °C, which might explain the occurrence of SMEs in both the filament and 3D-printed specimens. Dynamic mechanical analysis (DMA) emphasized a local increase in storage modulus of 0.87–1.66 GPa that occurred during heating, which might explain the development of work-generating SME in both filament and 3D-printed specimens. These properties recommend 3D-printed parts made of R-PETG as active elements in low-price lightweight actuators operating between RT and 63 °C.
Engineered apoptotic bodies hitchhiking across the blood-brain barrier achieved a combined photothermal-chemotherapeutic effect against glioma

Background: Glioma as a highly lethal tumor is difficult to treat since the blood-brain barrier (BBB) restricts drug delivery into the brain. It remains a huge need for developing strategies allowing drug passage across the BBB with high efficacy. Methods: Herein, we engineered drug-loaded apoptotic bodies (Abs) loaded with doxorubicin (Dox) and indocyanine green (ICG) to cross the BBB for the treatment of glioma. The confocal laser scanning microscopy was used to characterize the structure and evaluate the hitchhiking effect of the Abs. The in vivo BBB-crossing ability and photothermal-chemotherapeutic effect of the drug-loaded Abs were investigated in mice orthotopic glioma model. Results: Engineered Abs loaded with Dox and ICG were successfully prepared. The Abs were phagocytized by macrophages, actively penetrate the BBB in vitro and in vivo utilizing the hitchhiking effect. The whole in vivo process was visualized by near-infrared fluorescence signal with a signal-to-background ratio of 7 in a mouse model of orthotopic glioma. The engineered Abs achieved a combined photothermal-chemotherapeutic effect, leading to a median survival time of 33 days in glioma-bearing mice compared to 22 days in the control group. Conclusions: This study presents engineered drug carriers with the ability to hitchhike across the BBB, providing new opportunities for the treatment of glioma.
Extracorporeal shock wave treatment for post‑surgical fracture nonunion: Insight into its mechanism, efficacy, safety and prognostic factors (Review)

Post-surgical fracture nonunion (PSFN) represents the failure to achieve cortical continuity at radiological examination after an orthopedic operation, which causes a considerable disease burden in patients with fractures. As one of the traditional treatment modalities, surgical therapy is associated with a high fracture union rate; however, post-surgical complications are not negligible. Therefore, less invasive therapies are needed to improve the prognosis of patients with PSFN. Extracorporeal shock wave treatment (ESWT) is a noninvasive method that presents a similar efficacy profile and favorable safety profile compared with surgical treatment. However, the application and detailed mechanism of ESWT in patients with PSFN remain unclear. The present review focuses on the mechanism, efficacy, safety and prognostic factors of ESWT in patients with PSFN, aiming to provide a theoretical basis for its application and improve the prognosis of these patients.
Unexpected recovery from complete deafness to normal hearing post surgical excision of a cerebellopontine angle meningioma: A case report

Background: Cerebellopontine angle (CPA) meningioma presents a significant management challenge due to its intricate relationship with the brainstem neurovascular bundles. The emphasis in the past has been on facial nerve preservation, but the current management standard is hearing preservation in patients with serviceable hearing; however, hearing restoration after complete loss is rare. We report an elderly man who had restoration of hearing in the right ear after complete loss following tumor resection through the retrosigmoid route. Case Description: A 73-year-old male patient presented with progressive hearing impairment in the right ear, culminating in hearing loss for about 2 months (the American Academy of Otolaryngology-Head and Neck Surgery [AAO-HNS] class D). He also had mild cerebellar symptoms, but other cranial nerves and long tracts were normal. Brain magnetic resonance imaging confirmed a right CPA meningioma, and he had tumor resection through the retrosigmoid route using meticulous microsurgical technique with vestibulocochlear nerve preservation, facial nerve monitoring, and intraoperative video angiography. He had restoration of hearing on follow-up (the American Academy of Otolaryngology-Head and Neck Surgery class A). Histology confirmed World Health Organization central nervous system grade 1 meningioma. Conclusion: This case illustrates that hearing restoration is possible after complete loss in patients with CPA meningioma. We advocate hearing preservation surgery even in patients with non-serviceable hearing, as the chance of hearing recovery is possible.
