Abstract
Purpose To report the prevalence of late postoperative opacification of a hydrophilic and hydrophobic acrylic intraocular lens (IOL) and to assess the risk factors in a subset of 212
eyes of patients referred to the University Eye Department in Basel, Switzerland.
Design Retrospective case series.
Methods A survey was performed at all large ophthalmological clinics in Switzerland regarding exchanged Lentis LS-502-1 lenses, and the number of affected eyes was counted. Moreover,
consecutive patients who were referred to a tertiary clinic between September 2015 and November 2016 with Lentis LS-502-1 opacification were investigated. Peri- and postoperative charts,
medical history, and topical and systemic medications were assessed.
Results A total of 674 opacified Lentis LS-502-1 lenses have been reported in Switzerland, and 212 consecutive eyes of 182 patients were included in the study. All IOLs had a similar
pattern of opacification with a yellowish, diffuse appearance, and most of them showed a small, paracentral, roundish area that was less affected or not at all. Arterial hypertension (73%),
hypercholesterolemia (34%), and diabetes (21%) were the main associated systemic diseases, and statins (34%) and betablockers (34%) were the main treatments used.
Conclusions The prevalence of IOL opacification was 9.9%. No associated systemic eye disease or medications could be detected, which was implicated in the opacification process. The
reason for opacification remains unclear, but it seems to be unrelated to the patientʼs state; therefore, it is attributed to primary calcification.

Authors: Eppenberger Leila Sara , Sturm Veit 
Published: April 2023

Abstract
Purpose Assessment of diagnostic and therapeutic strategies currently used in routine practice for myopia management in Europe.
Methods Online survey study including 11 main questions. The questionnaire was sent to members of the European Paediatric Ophthalmology Society (EPOS). The following items and
questions were surveyed: I. Profession and workplace of the survey participants. II. Preventive measures and recommendations for myopia management, a) regarding reading distance and near
work, b) optical tools, i.e., application of Defocus Incorporated Multiple Segments (DIMS) glasses, near additions, or contact lenses, and c) the application of atropine eye drops. III.
Application of additional diagnostic tools.
Results Forty-eight individuals completed the survey. Of the respondents, 88% (n = 42) affirmed that they generally gave advice on strategies for myopia prevention and management
strategies. Almost all study participants (n = 41; 85%) recommend outdoor time as a preventive measure. The recommendation on near distance is given less frequently, with 28 (58%)
participants confirming that they do recommend a “safe” reading distance, and 15 (31%) negating this. Eight (17%) survey participants recommend using near addition glasses, while 36 (75%) do
not. Similarly, 35 (73%) respondents do not apply DIMS glasses and 8 (17%) apply them. Fourteen (29%) participants recommend myopia-reducing contact lenses while 30 (63%) do not, and 29
(60%) confirmed that they applied atropine eye drops to slow myopia progression while 14 (29%) do not prescribe these eye drops. The majority of respondents (n = 25; 86%) who prescribe
atropine eye drops use atropine 0.01% eye drops.
Conclusions Prevention and therapeutic management of childhood myopia is an essential part in the daily routine of pediatric ophthalmologists. Substantial agreement was found for the
protective role of outdoor time (85%). The only common therapeutic approach is the administration of atropine eye drops (60%).

Published: April 2023

Abstract
Purpose The goal of this study was to investigate the use of spectacles in everyday life after bilateral cataract surgery with a preoperative refractive target of emmetropia in both
eyes. In addition, we analyzed the total cost of spectacles and the patientʼs visual satisfaction at least 6 months after surgery.
Methods Patients after bilateral cataract surgery with implantation of an aspheric monofocal IOL (Tecnis 1, Johnson & Johnson) with a preoperative refractive target of emmetropia
in both eyes and a documented refractive outcome were included in this prospective observational study. In a phone interview ≥ 6 months after surgery, the following items were assessed: type
of spectacles purchased and overall cost, type of activity with and duration of spectacle wear, and satisfaction with the visual situation.
Results Seventy patients were included in this study. Depending on their postoperative refraction, patients were divided into group A (n = 27) with perfect emmetropia in both eyes
(i.e., spherical equivalent [SE] of ≥ − 0.25 D to ≤ + 0.25 D), group B (n = 21) with achieved emmetropia in one eye (i.e., SE of ≥ − 0.25 D to ≤ + 0.25 D) and a myopic refraction in the
other eye (< − 0.25 D), and group C (n = 22) with bilateral myopic results (SE of < − 0.25 D). Overall, 84% of patients had purchased new spectacles, mostly varifocals (59%) or reading
glasses (24%) at the median cost of 980 Swiss Francs (mean: CHF 912 ± 746). Despite patientsʼ initial reasoning for their lens choice to require reading glasses only, varifocal glasses were
worn for more than 50% or all of awake time by 48% of patients in group A, 43% in group B, and 68% in group C. Despite their regular spectacles use, patientsʼ visual satisfaction was very
high in all three groups.
Conclusions Most patients who achieve perfect bilateral emmetropia after implantation of monofocal aspheric lenses buy varifocal spectacles within 6 months, and more than half of all
patients use their varifocal spectacles for more than 50% of their awakening time. The costs for such spectacles are high.

Abstract
Background and study aims Up to 80 % of patients with pancreatic adenocarcinoma develop locoregional recurrence after primary resection. However, the detection of recurrent pancreatic ductal adenocarcinoma (RPDAC) after pancreatic surgery can be challenging because of difficulty distinguishing locoregional recurrence from normal postoperative or post-radiation changes. We sought to evaluate the utility of endoscopic ultrasound (EUS), in detecting pancreatic adenocarcinoma recurrence after surgical resection and its impact on the clinical management of patients.
Patients and methods This was a retrospective study of all pancreatic cancer patients who underwent EUS post-resection at two tertiary care centers between January 2004 and June 2019.
Results Sixty-seven patients were identified. Of these, 57 (85 %) were diagnosed with RPDAC, resulting in change in clinical management of 46 (72 %) patients. EUS identified masses not seen on computed tomography, magnetic resonance imaging, or positron emission tomography in seven (14 %).
Conclusions EUS is useful in detecting RPDAC after pancreatic surgery and can lead to significant impact on clinical management.
Non-nucleophilic Grignard Synthesis of Bridged Pyridine–Oxazoline Ligands and Evaluation in Palladium-Catalysed Allylic Alkylation
Authors: O’Leary Patrick , Sutton Grace 
Published: April 2023

AbstractThe synthesis of eight pyridine-oxazoline ligands, five of which have never been reported previously, is described. The ligands were prepared in two efficient steps, initially preparing 2-pyridyl alkylnitriles, followed by their conversion into oxazolines ligands using chiral amino alcohols and zinc chloride. The 2-pyridyl nitriles are prepared via a novel SNAr alkylation reaction of 2-bromopyridine with alkyl nitriles using methylmagnesium chloride as a non-nucleophilic base in conjunction with an amine mediator. This methodology allows preparation of the existing gem-dimethyl motif and its elaboration beyond previously prepared ligands in fewer steps with simplicity and scalability. The toleration of variation in the nitrile, halopyridine, and amino alcohol starting materials allows for other novel bridging substitution which gives new ligands with enhanced reactivity. The library of bridging ligands was applied to the Pd-catalysed allylic alkylation of 1,3-diphenylprop-2-enyl acetate with dimethyl malonate and afforded conversions of up to 100% and enantioselectivities of up to 68%.

Daily and annual changes in light are processed by central clock circuits that control the timing of behavior and physiology. The suprachiasmatic nucleus (SCN) in the anterior hypothalamus processes daily photic inputs and encodes changes in day length (i.e., photoperiod), but the SCN circuits that regulate circadian and photoperiodic responses to light remain unclear. Somatostatin (SST) expression in the hypothalamus is modulated by photoperiod, but the role of SST in SCN responses to light has not been examined. Our results indicate that SST signaling regulates daily rhythms in behavior and SCN function in a manner influenced by sex. First, we use cell-fate mapping to provide evidence that SST in the SCN is regulated by light via de novo
Sst
activation. Next, we demonstrate that

Sst
-/-

mice display enhanced circadian responses to light, with increased behavioral plasticity to photoperiod, jetlag, and constant light conditions. Notably, lack of

Sst
-/-

eliminated sex differences in photic responses due to increased plasticity in males, suggesting that SST interacts with clock circuits that process light differently in each sex.

Sst
-/-

mice also displayed an increase in the number of retinorecipient neurons in the SCN core, which express a type of SST receptor capable of resetting the molecular clock. Last, we show that lack of SST signaling modulates central clock function by influencing SCN photoperiodic encoding, network after-effects, and intercellular synchrony in a sex-specific manner. Collectively, these results provide insight into peptide signaling mechanisms that regulate central clock function and its response to light.
Optimization of temperature stability and sensitivity of the giant magnetoimpedance effect in meander shaped Co-based amorphous ribbon using DC-biased current for sensor application
Authors: Pan Lizi , Ma Lei , Wu Huiliang , Li Xiaolei , Ye Yuchen , Wang Jianbo , Liu Qingfang 
Published: April 2023

Abstract
The influence of DC-biased current (I
DC) on the longitudinal giant magnetoimpedance (GMI) effect in Co-based amorphous ribbon with a meander structure, taken from room temperature to 120 °C, has been investigated. The results show that I
DC increases the temperature stability of the impedance of amorphous ribbon at 20 MHz. By deriving the expression of the transverse permeability according to a magnetization rotation model, we attributed the improved temperature stability to the combined effect of temperature and bias field H
DC generated by I
DC on the transverse permeability. It is also shown that I
DC not only effectively inhibits the weakening of the GMI ratio at high temperature, but also significantly improves the GMI sensitivity. This will help to achieve sensitive low magnetic field measurement under large temperature fluctuation.
Association of oppositely charged polyelectrolyte and surfactant in solution: equilibrium and nonequilibrium features
Authors: Guzmán Eduardo , Maestro Armando , Ortega Francisco , Rubio Ramón G 
Published: April 2023

Abstract
The association of polyelectrolytes and surfactants bearing charges of opposite signs has been for long time considered under an equilibrium framework. However, this is far to provide a true description of the physico-chemical rules of the association process when kinetically arrested nonequilibrium states are formed. This is the result of specific interaction pathways between the polyelectrolyte chains and the surfactant molecules determined by the mixing procedure and the mixture composition. In fact, the specific characteristics of the method used for the mixture can induce local inhomogeneities in the mixture composition which can govern the properties of the obtained supramolecular aggregates, driving to the systems to a situation far from the true equilibrium. This topical review tries to provide to the reader a general perspective of the role of the nonequilibrium aspects in the control of the polyelectrolyte-surfactant association process, and how these impact on the obtained supramolecular nanoassemblies, and their properties.

Abstract
This work demonstrates a facile and efficient methodology to synthesize a composite material of zeolitic imidazolate frameworks (ZIFs) and laser-induced graphene (LIG). This ZIF-67 loaded LIG composite (ZIF-67/LIG) has been adequately characterized for its morphology and structure, and its electrochemical performance has been specifically examined. As supercapacitors (SCs) electrode material, the ZIF-67/LIG composite exhibits superb electrochemical performance, owing to the inherent high porosity, abundant active sites, large specific surface area of ZIF-67, and the excellent conductive three-dimensional hierarchical porous network structure provided by LIG. In three-electrode system, ZIF-67/LIG composite electrode displays outstanding areal specific capacitance (C
A) of 135.6 mF cm−2 at a current density of 1 mA cm−2 with 1 M Na2SO4 aqueous electrolyte, which is far greater than that of pristine LIG (7.7 mF cm−2). Furthermore, the ZIF-67/LIG composite has been fabricated into an all-solid-state planar micro-supercapacitor (MSC). This ZIF-67/LIG MSC exhibits an impressive C
A of 38.1 mF cm−2 at a current density of 0.20 mA cm−2, a good cycling stability of 80.3% capacitance retention after 3000 cycles, and a high energy density of 5.29 μWh cm−2 at a power density of 0.1 mW cm−2. All electrochemical results clearly manifest that as-prepared ZIF-67/LIG composite can be a candidate in energy storage field with exciting possibilities.

Abstract
Preparing high quality non-polar aluminum nitride (AlN) templates is the key to improving the performance of non-polar deep-ultraviolet light-emitting diodes. In this study, we investigated the effect of buffer layer on the crystallinity and surface morphology of a-plane AlN films regrown by pulsed-flow mode (PM) metal-organic vapor phase epitaxy (MOVPE). Three buffer layers were compared including low-temperature AlN buffer layer grown by MOVPE (MO-buffer), sputtered AlN buffer layer (SP-buffer), and high-temperature annealed sputtered AlN buffer layer (HTA-buffer). It is found that the (11-20) plane x-ray rocking curve-full width at half maximum (XRC-FWHM) values of a-plane AlN films are significantly reduced after the regrowth process. Thanks to the high crystalline quality of HTA-buffer, AlN regrown on HTA-buffer exhibits the smallest (11-20) plane XRC-FWHM values of 1260/1440 arcsec along the [0001]/[1-100] direction. The mosaic tilt and basal plane stacking fault density are estimated to be 0.41° and 1.76

×

106 cm−1, respectively. The surface shows a uniform stripe-like pattern with the lowest root mean square value of 0.82 nm. Furthermore, the a-plane AlN epilayer regrown on HTA-buffer displays a weak in-plane stress anisotropy and high optical transmittance in the ultraviolet-visible region. Our work suggests that combining the PM regrowth with HTA-AlN buffer layer is a promising route to prepare high-quality a-plane AlN templates for efficient non-polar deep-ultraviolet light emitters.

Published: April 2023

Abstract
The density functional theory (DFT) levels B3LYP, B3PW91 and CAM-B3LYP/6–31+G(d) were used to systematically evaluate the reactivity, electronic, linear and non-linear optical (NLO) properties of the titanium dioxide, boron and nitrogen-doping C45H15-like carbon nanocone. Due to this doping, the |HOMO-LUMO| energy gap of the initial carbon nanocone (CO) has narrowed considerably and some values of the |HOMO-LUMO| gap energy of the derivatives formed are lower than 1 eV. This result shows that some of the derivatives may be used as suitable semiconductor materials and others as highly demanded-superconducting materials in the electronics industry. In addition, all these studied derivatives showed a red-shifted absorption maximum, however only the obtained derivative by substituting both five carbon atoms with five nitrogen atoms and ten carbon atoms with ten boron atoms (N5B10) exhibits the highest absorption capacity in the visible range, implying that the latter could be a promising candidate in photovoltaic devices. Finally, the first-order hyperpolarizability values of all the formed derivatives are largely superior to that of the pure carbon nanocone (CO) and also to that of the reference compound para-nitroaniline (p-NA), which leads us to say that these formed derivatives may be suitable candidates for NLO applications. Also, according to our investigations, the boron and nitrogen atom arrangements established within our studied carbon nanocone predict exothermic reactions in contrast to the data collected in the literature that predict endothermic reactions. Furthermore, with respect to dopant enhancements to our studied carbon nanocone, it should be noted that the simultaneous manipulation of the boron and nitrogen heteroatoms with a higher probability of boron presence than nitrogen offers new opportunities to improve the overall C5n
2H5n carbon nanocone properties with n ≥ 3.

Published: April 2023

Abstract
Based on the optical properties of waveguide-coupled surface plasmon resonance, a sensor of surface plasmon coupled waveguide resonance with double discrete states generated by the upper and lower waveguide structures combined with prisms and Au films, respectively, is proposed. In this paper, the sensing structure is studied numerically and analytically, and the transmission characteristics of surface equipartition excitations are analyzed and elaborated in-depth in combination with the reflection angle spectrum, as well as the generation and evolution mechanism of dual Fano resonance at different incidence angles at fixed wavelengths. The structural model of Fano resonance sensing based on angle modulation is established, and the sensing characteristics are analyzed to produce electromagnetic field enhancement at low-angle Fano. The mathematical model between structural parameters and spectral performance is established using back propagation (BP) neural network, and the particle swarm optimization (PSO) algorithm is used to find the input structural parameters corresponding to the optimal performance, The results show that the quality factor of resonance (FOM) and sensitivity is significantly improved; When it is used in the field of biosensing, the response curves of Fano with different angles of high and low to concentration are quite different, thus realizing high precision detection of different concentrations of solutions and reflecting excellent sensing performance.
Entanglement based six-state quantum cryptography protocol: exact proof of security
Authors: Kulik S P , Molotkov S N 
Published: April 2023

Abstract
A novel quantum key distribution (QKD) protocol is proposed, which uses six states of three states in two bases. The protocol provides a greater range of key distribution compared to known QKD protocols. The protocol has an accurate proof of secrecy based on fundamental entropy uncertainty relations, the use of which is possible with the entanglement version of the protocol. The implementation of the protocol does not require adjustment of the polarization state at the output of the communication line, since the receiving side does not use active polarization-sensitive elements—phase modulators, which virtually excludes active probing of the active elements of the system.
