Lemniscate-like constants and infinite series
Authors: Campbell John M. , Chu Wenchang 
Published: August 2021

AbstractWe introduce lemniscate-like constants by “twisting” the standard series expansions of the classical lemniscate constants via harmonic-type factors in the summand. Closed-form evaluations for these constants are established, and are then utilized to construct alternate proofs of summation formulae obtained recently via coefficient-extraction techniques applied to Kummer’s classical hypergeometric identity.
De la Vallée Poussin inequality for impulsive differential equations
Authors: Akgöl Sibel Doğru , Özbekler Abdullah 
Published: August 2021

Abstract
The de la Vallée Poussin inequality is a handy tool for the investigation of disconjugacy, and hence, for the oscillation/nonoscillation of differential equations. The results in this paper are extensions of former those of Hartman and Wintner [Quart. Appl. Math. 13 (1955), 330–332] to the impulsive differential equations. Although the inequality first appeared in such an early date for ordinary differential equations, its improved version for differential equations under impulse effect never has been occurred in the literature.
In the present study, first, we state and prove a de la Vallée Poussin inequality for impulsive differential equations, then we give some corollaries on disconjugacy. We also mention some open problems and finally, present some examples that support our findings.
Effect of nanoscale dielectric environments on concentration quenching

Published: August 2021

Abstract
We have studied the dependence of concentration quenching of luminescence (donor–acceptor energy transfer) on the thickness d of dye-doped polymeric films (HITC:PMMA) and found its strong inhibition at small values of d. This phenomenon is tentatively explained by a limited number of acceptors, which donors’ excitation can reach in thin samples, if the film’s thickness is comparable to the diffusion length of the energy transfer. The latter mechanism, along with effective reduction of the dye concentration, is responsible for an inhibition of the concentration quenching of dye molecules impregnating porous alumina membranes. The elongation of emission kinetics in thick (≥3 μm) HITC:PMMA films is cautiously attributed to the samples’ crystallinity.

Abstract
Nanobody-targeted photodynamic therapy (NB-PDT) has been developed as a potent and tumor-selective treatment, using nanobodies (NBs) to deliver a photosensitizer (PS) specifically to cancer cells. Upon local light application, reactive oxygen species are formed and consequent cell death occurs. NB-PDT has preclinically shown evident success and we next aim to treat cats with oral squamous cell carcinoma (OSCC), which has very limited therapeutic options and is regarded as a natural model of human head and neck SCC. Immunohistochemistry of feline OSCC tissue confirmed that the epidermal growth factor receptor (EGFR) is a relevant target with expression in cancer cells and not in the surrounding stroma. Three feline OSCC cell lines were employed together with a well-characterized human cancer cell line (HeLa), all with similar EGFR expression, and a low EGFR-expressing human cell line (MCF7), mirroring the EGFR expression level in the surrounding mucosal stroma. NBA was identified as a NB binding human and feline EGFR with comparable high affinity. This NB was developed into NiBh, a NB-PS conjugate with high PS payload able to effectively kill feline OSCC and HeLa cell lines, after illumination. Importantly, the specificity of NB-PDT was confirmed in co-cultures where only the feline OSCC cells were killed while surrounding MCF7 cells were unaffected. Altogether, NiBh can be used for NB-PDT to treat feline OSCC and further advance NB-PDT towards the human clinic.
Non-orthogonal polarization multiplexed metasurfaces for tri-channel polychromatic image displays and information encryption

Published: August 2021

Abstract
Interference usually occurs between two non-orthogonally polarized light beams. Hence, metasurface enabled polarization multiplexing is generally conducted under two orthogonal polarization states to realize independent intensity and/or phase modulations. Herein, we show that polarization multiplexed metasurfaces can work under three non-orthogonal polarization states to realize tri-channel image displays with independent information encoding. Specifically, enabled by orientation degeneracy, each nanostructure of the metasurface operates with triple-manipulations of light, i.e., two channels for independent intensity manipulation under π/4 and 3π/8 linearly polarized (LP) light, respectively, and one channel for phase manipulation without polarization control. We experimentally demonstrate this concept by recording one continuous-brightness polychromatic image and one binary-brightness polychromatic image right at the metasurface plane, while a continuous-brightness polychromatic image is reconstructed in the far field, corresponding to three independent channels, respectively. More interestingly, in another design strategy with separated image encoding of two wavelengths, up to six independent image-display channels can be established and information delivery becomes safer by utilizing encryption algorithms. With the features of high information capacity and high security, the proposed meta-devices can empower advanced research and applications in multi-channel image displays, orbital angular momentum multiplexing communication, information encryption, anti-counterfeiting, multifunctional integrated nano-optoelectronics, etc.

Abstract
Strong-field photoemission from nanostructures and the associated temporally modulated currents play a key role in the development of ultrafast vacuum optoelectronics. Optical light fields could push their operation bandwidth into the petahertz domain. A critical aspect of their functionality in the context of applications is the impact of charge interaction effects. Here, we investigated the photoemission and photocurrents from nanometric tungsten needle tips exposed to carrier-envelope phase (CEP)-controlled few-cycle laser fields. We report a characteristic rapid increase in the intensity-rescaled cutoff energies of emitted electrons beyond a certain intensity value. By comparison with simulations, we identify this feature as the onset of charge-interaction dominated photoemission dynamics. Our results are anticipated to be relevant also for the strong-field photoemission from other nanostructures, including photoemission from plasmonic nanobowtie antennas used in CEP-detection and for PHz-scale devices.

Tailoring the physical characteristics of solution blown cellulosic nonwovens by various post-treatments
Authors: Jedvert Kerstin , Viklund Linnea , Alkhagen Mårten , Köhnke Tobias , Theliander Hans 
Published: August 2021

Abstract
Nonwovens are increasing in demand due to their versatility which enables use in a broad range of applications. Most nonwovens are still produced from fossil-based resources and there is thus a need to develop competitive materials from renewable feedstock. In this work, nonwovens are produced from cellulose via a direct solution blowing method. Cellulose was dissolved using the ionic liquid 1-ethyl-3-methylimidazolium acetate (EMIMAc) and was regenerated into nonwovens by coagulation in water. The properties of such nonwovens were previously rather stiff and papery-like and the aim of this work was to improve the softness and feel of the materials by simple adjustments of the post-processing steps, i. e. washing and drying. It was shown that by primarily changing the drying method, it was possible to create a much softer and bulkier material using the same solution blowing parameters.
Early Neolithic Settlement Patterns in Northern Dalmatia
Authors: Horvat Kristina 
Published: August 2021

Abstract
This article focuses on the early Neolithic settlement patterns in northern Dalmatia, located in the middle of the eastern Adriatic. At the present state of research, a total of 35 Neolithic sites have been known in this region, 26 of which belong to the Early Neolithic. Observing the type and character of the early Neolithic sites, their micro-topographic features, proximity and availability of resources, organization of life in relation to environment requirements, continuity of life at a particular location, and economic strategies, we come to the conclusion that the early Neolithic settlement patterns in northern Dalmatia were determined by natural landscape and its resources. They are the postulate and basis for the development of different aspects of social life and economy, as well as the starting point for the interpretation of the character and dynamics of the development of the early Neolithic communities in this area. The site locations, stratigraphic relations, and radiocarbon dating also suggest movements of the early Neolithic communities. The movements seem to have taken place exclusively within the fields. Discussion whether it was one or several simultaneous communities/settlements remains limited, since the state of research does not allow precise attribution of the site to certain chronological segments of the Early Neolithic.
Gender-based violence in higher education and research: a European perspective
Authors: Bosco Damous Licia , Guillopé Colette 
Published: August 2021

Abstract
The gender gap in science is intrinsically linked to gender-based violence in academia. Gender-based violence is a form of discrimination against women that occurs in an academic environment, and it often takes the form of sexual harassment. Some European countries, such as France, Italy, and Ireland, have solid legal systems in place to address sexual harassment in academia. However, as the report of the European Research Area and Innovation Committee Standing Working Group on sexual harassment points out, not all European countries have legislation in this area, or if they do, it is often ineffective. While national surveys generally show that it is difficult to prevent or combat sexual harassment in universities, practices related to corporate social responsibility could be used to start the conversation about the social responsibility of universities to fight against sexual harassment, which is reflected in this article.
Electrospinning of chitosan-based nanofibers: from design to prospective applications
Authors: Anisiei Alexandru , Oancea Florin , Marin Luminita 
Published: August 2021

Abstract
Chitosan is a biopolymer originating from renewable resources, with great properties which make it an attractive candidate for plenty of applications of contemporary interest. By manufacturing chitosan into nanofibers using the electrospinning method, its potential is amplified due to the enhancement of the active surface and the low preparation cost. Many attempts were made with the aim of preparing chitosan-based nanofibers with controlled morphology targeting their use for tissue engineering, wound healing, food packaging, drug delivery, air and water purification filters. This was a challenging task, which resulted in a high amount of data, sometimes with apparent contradictory results. In this light, the goal of the paper is to present the main routes reported in the literature for chitosan electrospinning, stressing the advantages and disadvantages of each of them. Special emphasis is placed on the influence of various electrospinning parameters on the morphological characteristics of the fibers and their suitability for distinct applications.

This paper is an extension of
[S. Liang,
A mechanical model of Brownian motion for one massive particle including slow light particles,
J. Stat. Phys. 170 2018, 2, 286–350].
Precisely, we consider a system of one massive particle interacting with an ideal gas,
evolved according to non-random Newton mechanical principles, via interaction potentials,
without any assumption requiring that the initial energies of the environmental particles should be
restricted to be “high enough”.
We prove that, as in the high-dimensional case,
the position/velocity process of the massive particle converges to a diffusion process
when the mass of the environmental particles converges to 0,
while the density and the velocities of them go to infinity.
Delamination properties and in situ damage monitoring of z-pinned carbon fiber/epoxy composites
Authors: Che Zhe , Wang Han , Wang Shaokai , Gu Yizhuo , Li Min 
Published: August 2021

Abstract
Carbon-fiber-reinforced composites with layer stacking structures are sensitive to delamination crack. To improve the interlaminar properties and further explore the capability of in situ damage monitoring of the laminate, CCF300 and CCF800 carbon fiber pins were selected to fabricate the z-pinned composites. Compared with the control sample, the G
IC values of CCF300 and CCF800 z-pinned composites are increased by 398 and 378%, respectively. This indicates that the delamination resistance improvement of the laminates is dominated by the z-pin debonding and pull-outs. The electrical resistance of the laminates was utilized to in situ monitor the crack propagation within the composite laminate. The results show that the presence of the z-pins enhances the sensitivity of damage detection. The ΔR/R
0 of CCF800 z-pinned composite is nearly three times that of the control sample at the moment the crack length reaches 110 mm. Crack length–displacement curves were obtained according to the relationship between ΔR and Δa, which clearly displayed the steady or stick-slip crack growth of the laminates with or without z-pins, respectively. Visualization of the crack growth process can provide a novel method for the delamination failure analysis of the composite.
Guided self-determination in treatment of chronic pain – a randomized, controlled trial
Authors: Pickering Anne Paarup , Bache Nina Jeanette , Estrup Stine 
Published: August 2021

Abstract

Objectives
To test whether Guided Self-Determination (GSD) used in chronic pain management could improve the health-related quality of life, patient activation and sense of coherence (SoC) as a measurement of life skills in patients with chronic pain. The method has been shown to be effective in other chronic conditions, but has not been tested in chronic pain.

Methods
A three-site randomised, controlled trial at three major multidisciplinary pain centres in Denmark. 200 patients were included and randomised. In the intervention period, both groups had regular visits to the pain centre with both doctors and nurses. The intervention group additionally received the GSD intervention with weekly sessions for eight weeks. Data were collected from February 2013 to July 2016 and consisted of three questionnaires answered before and after the 8-week intervention period, and after six months. The primary outcome was self-reported health related quality of life. Secondary outcomes included self-reported activation and SoC.

Results
We found no clinically relevant difference between the groups for health-related quality of life, patient activation or SoC at either baseline, at three months or at six months. We also analysed data for trends over time using mixed model analysis, and this did not show any significant differences between groups.

Conclusions
GSD did not improve health-related quality of life, patient activation or SoC when administered to patients with chronic pain treated in a multidisciplinary pain centre. New research is recommended using a combination of self-reported and objective measures and longer follow-up.
Is this really trigeminal neuralgia? Diagnostic re-evaluation of patients referred for neurosurgery
Authors: Slettebø Haldor 
Published: August 2021

Abstract

Objectives
Patients with facial pain are sometimes referred for neurosurgical treatment with a poorly documented diagnosis of trigeminal neuralgia. In such cases, neurosurgery will usually not be helpful. We conducted a re-evaluation of the diagnosis in patients referred for neurosurgical treatment of presumed trigeminal neuralgia. Our objective was to find out why and how often misdiagnosis occurred.

Methods
A retrospective study was done in consecutive first-time patients referred for trigeminal neuralgia to our outpatient clinic in 2019. We used five ICHD-3-based clinical criteria to verify or exclude the diagnosis. In patients where trigeminal neuralgia was excluded, we established a diagnosis for their facial pain based upon medical history and a physical examination by a neurosurgeon – often supplemented with examination by an oral surgeon.

Results
Thirty-eight patients were referred for presumed trigeminal neuralgia. Only 17 of them fulfilled the five criteria and were diagnosed with trigeminal neuralgia. In 20 of the remaining 21 patients trigeminal neuralgia could be clearly excluded, while one of the patients had a periodontitis closely mimicking trigeminal neuralgia. In 14 of the 21 patients we diagnosed temporomandibular dysfunction or dental conditions. MRI scans had detected low-grade neurovascular contacts in 13 of the 21 patients, a finding that was clearly overestimated by the referring neurologists in seven patients.

Conclusions
Overdiagnosis of trigeminal neuralgia was common in patients referred for neurosurgery, mostly due to insufficient clinical evaluation combined with an overestimation of MRI-detected NVCs. The clinical diagnosis should be critically re-evaluated before recommending neurosurgery to patients referred for presumed trigeminal neuralgia.
Disentangling ‘sciatica’ to understand and characterise somatosensory profiles and potential pain mechanisms
Authors: Tampin Brigitte , Lind Christopher , Jacques Angela , Slater Helen 
Published: August 2021

Abstract

Objectives
The study aimed to investigate if patients with lumbar radicular pain only and those with combined lumbar radicular pain + radiculopathy differ in their somatosensory profiles and pain experiences.

Methods
Quantitative sensory testing (QST) was performed in 26 patients (mean age 47 ± 10 years, 10 females) with unilateral leg pain in the L5 or S1 distribution in their main pain area (MPA) and contralateral mirror side, in the relevant foot dermatome on the symptomatic side and in the hand dorsum. Pain experience was captured on the painDETECT.

Results
Eight patients presented with lumbar radicular pain only and 18 patients with combined radicular pain + radiculopathy. Patients with radicular pain only demonstrated widespread loss of function (mechanical detection) bilaterally in the MPA (p<0.003) and hand (p=0.002), increased heat sensitivity in both legs (p<0.019) and cold/heat sensitivity in the hand (p<0.024). QST measurements in the dermatome did not differ compared to HCs and patients with radiculopathy. Patients with lumbar radiculopathy were characterised by a localised loss of function in the symptomatic leg in the MPA (warm, mechanical, vibration detection, mechanical pain threshold, mechanical pain sensitivity p<0.031) and dermatome (mechanical, vibration detection p<0.001), consistent with a nerve root lesion. Pain descriptors did not differ between the two groups with the exception of numbness (p<0.001). Patients with radicular pain did not report symptoms of numbness, while 78% of patients with radiculopathy did.

Conclusions
Distinct differences in somatosensory profiles and pain experiences were demonstrated for each patient group, suggesting differing underlying pain mechanisms.
