Employees' support strategies for mental wellbeing during and beyond the COVID-19 pandemic: Recommendations for employers in the UK workforce.

Throughout the COVID-19 pandemic, and beyond for many businesses, employees have had to adapt to new ways of working due to disruptions in traditional practices. It is therefore crucial to understand the new challenges that employees are facing when it comes to taking care of their mental wellbeing at work. To that end, we distributed a survey to full-time UK employees (N = 451) to explore how supported they felt throughout the pandemic, and to identify whether there are any additional types of support they would like to receive.

Multicomponent odd-parity superconductivity in UAu at high pressure.

We report that high-quality single crystals of the hexagonal heavy fermion material uranium diauride (UAu) become superconducting at pressures above 3.2 GPa, the pressure at which an unusual antiferromagnetic state is suppressed. The antiferromagnetic state hosts a marginal fermi liquid and the pressure evolution of the resistivity within this state is found to be very different from that approaching a standard quantum phase transition.

New sustainable ternary copper phosphide thermoelectrics.

The thermoelectric performance of ACuP (A = Mg and Ca) with abundant elements and low gravimetric density is reported. Both systems are p-type doped by intrinsic Cu vacancy defects, have large power factors and promising figures of merit, reaching = 0.5 at 800 K.

Non-Fermi liquid behavior below the Néel temperature in the frustrated heavy fermion magnet UAu.

The term Fermi liquid is almost synonymous with the metallic state. The association is known to break down at quantum critical points (QCPs), but these require precise values of tuning parameters, such as pressure and applied magnetic field, to exactly suppress a continuous phase transition temperature to the absolute zero. Three-dimensional non-Fermi liquid states, apart from superconductivity, that are unshackled from a QCP are much rarer and are not currently well understood.

Rational design, synthesis and testing of novel tricyclic topoisomerase inhibitors for the treatment of bacterial infections part 2.

Building on our previously-reported novel tricyclic topoisomerase inhibitors (NTTIs), we disclose the discovery of REDX07965, which has an MIC of 0.5 μg mL against , favourable pharmacokinetic properties, selectivity human topoisomerase II and an acceptable toxicity profile. The results herein validate a rational design approach to address the urgent unmet medical need for novel antibiotics.

Rational design, synthesis and testing of novel tricyclic topoisomerase inhibitors for the treatment of bacterial infections part 1.

The alarming reduction in drug effectiveness against bacterial infections has created an urgent need for the development of new antibacterial agents that circumvent bacterial resistance mechanisms. We report here a series of DNA gyrase and topoisomerase IV inhibitors that demonstrate potent activity against a range of Gram-positive and selected Gram-negative organisms, including clinically-relevant and drug-resistant strains. In part 1, we present a detailed structure activity relationship (SAR) analysis that led to the discovery of our previously disclosed compound, REDX05931, which has a minimum inhibitory concentration (MIC) of 0.

Field-Induced Modulated State in the Ferromagnet PrPtAl.

The theory of quantum order-by-disorder (QOBD) explains the formation of modulated magnetic states at the boundary between ferromagnetism and paramagnetism in zero field. PrPtAl has been argued to provide an archetype for this. Here, we report the phase diagram in magnetic field, applied along both the easy a axis and hard b axis.

Novel C-7 carbon substituted fourth generation fluoroquinolones targeting N. Gonorrhoeae infections.

Delafloxacin, a fourth-generation anionic fluoroquinolone (FQ) was approved in 2019 for community acquired bacterial pneumonia (CARP). It has broad spectrum activity and an improved class-related toxicity profile. However, it has recently failed a Phase 3 clinical trial for treatment of N.

Composition dependence of the superconducting properties of UTe.

A better understanding of the synthesis conditions, composition and physical properties of UTeare required to interpret previously reported unconventional superconductivity. Here we report how the superconducting properties of single crystals depend on the ratio of elements present in their synthesis by chemical vapour transport. We have obtained crystals with the highest reported ambient pressureand a larger superconducting heat capacity jump from a growth with a U:Te ratio different from that widely used in the literature.

The effectiveness of health behavior change interventions in managing physical health in people with a psychotic illness: A systematic review.

Purpose: People living with psychotic illness disproportionately experience more comorbidities and have a markedly shorter life expectancy compared to the general population. This review evaluates the effectiveness of health behavior change interventions in improving health outcomes in this group.

Design And Methods: All studies included objective physical health measures or health behaviors as the main outcome measures and experimental design with baseline and follow-up quantitative data.

Molecular memory with downstream logic processing exemplified by switchable and self-indicating guest capture and release.

Molecular-logic based computation (MLBC) has grown by accumulating many examples of combinational logic gates and a few sequential variants. In spite of many inspirations being available in biology, there are virtually no examples of MLBC in chemistry where sequential and combinational operations are integrated. Here we report a simple alcohol-ketone redox interconversion which switches a macrocycle between a large or small cavity, with erect aromatic walls which create a deep hydrophobic space or with collapsed walls respectively.

Composition-tuning in a solid-state electrotransport furnace with active thermal expansion compensation.

A new solid-state electrotransport (SSE) apparatus for refining ultra-pure single crystals of metallic compounds under ultra-high vacuum is described. The setup employs a novel thermal expansion compensation mechanism to minimize mechanical stress on the sample during refinement with cold clamps for contamination-less purification at elevated temperatures. The apparatus is designed to tune the composition of initially slightly off-stoichiometric samples.

Piston cylinder cell for high pressure ultrasonic pulse echo measurements.

Ultrasonic techniques such as pulse echo, vibrating reed, or resonant ultrasound spectroscopy are powerful probes not only for studying elasticity but also for investigating electronic and magnetic properties. Here, we report on the design of a high pressure ultrasonic pulse echo apparatus, based on a piston cylinder cell, with a simplified electronic setup that operates with a single coaxial cable and requires sample lengths of mm only. The design allows simultaneous measurements of ultrasonic velocities and attenuation coefficients up to a pressure of 1.

Efficacy of a Novel Tricyclic Topoisomerase Inhibitor in a Murine Model of Neisseria gonorrhoeae Infection.

There is an urgent need for new antibiotics to treat multidrug-resistant Neisseria gonorrhoeae In this report, the microbiology, in vivo pharmacokinetics, and efficacy of REDX05931, a representative novel tricyclic topoisomerase inhibitor, were evaluated. REDX05931 demonstrated high oral bioavailability in mice and reduced N. gonorrhoeae infection after a single dose in a mouse model of gonorrhea.

Biological profiling of novel tricyclic inhibitors of bacterial DNA gyrase and topoisomerase IV.

Objectives: The objective of this study was to characterize the in vitro and in vivo biological properties of a novel series of small-molecule bacterial type IIA topoisomerase inhibitors.

Methods: Bacterial susceptibility testing was performed by broth microdilution. Resistance frequencies were determined by plating bacteria onto agar containing test compound and enumerating mutants.

A laboratory-based Laue X-ray diffraction system for enhanced imaging range and surface grain mapping.

Although CCD X-ray detectors can be faster to use, their large-area versions can be much more expensive than similarly sized photographic plate detectors. When indexing X-ray diffraction patterns, large-area detectors can prove very advantageous as they provide more spots, which makes fitting an orientation easier. On the other hand, when looking for single crystals in a polycrystalline sample, the speed of CCD detectors is more useful.

Modification of fluorescent photoinduced electron transfer (PET) sensors/switches to produce molecular photo-ionic triode action.

The fluorophore-spacer1-receptor1-spacer2-receptor2 system (where receptor2 alone is photoredox-inactive) shows ionically tunable proton-induced fluorescence off-on switching, which is reminiscent of thermionic triode behavior. This also represents a new extension to modular switch systems based on photoinduced electron transfer (PET) towards the emulation of analogue electronic devices.

The relationship between anhedonia and positive, negative, and general symptomatology in patients with schizophrenia.

An inability to experience pleasure or a reduction in the ability to do so is a prominent feature of schizophrenia that is often included among the negative symptoms of the disorder. As a whole, dysfunction in the affective experience of pleasure in patients with schizophrenia is poorly understood and is mediated by a number of cognitive and emotional processes. Whilst there is evidence that patients with schizophrenia have an impaired ability to derive and experience pleasure from non-current tasks, there is some evidence that they report current pleasurable experiences similar to non-clinical control participants.

Global assessment of psychosocial functioning and predictors of outcome in schizophrenia.

Objective: This study identified predictors of psychosocial outcome in schizophrenia.

Method: A mixed group of patients diagnosed with schizophrenia were assessed as part of a routine clinical evaluation. A linear regression analysis was conducted in order to examine the effect of duration of untreated illness, number of previous hospitalisations, history of psychotic episodes and age at illness onset on patients' functioning, as assessed with the Global Assessment of Functioning (GAF) scale.

Anisotropic critical magnetic fluctuations in the ferromagnetic superconductor UCoGe.

We report neutron scattering measurements of critical magnetic excitations in the weakly ferromagnetic superconductor UCoGe. The strong non-Landau damping of the excitations we observe, although unusual, has been found in another related ferromagnet, UGe(2) at zero pressure. However, we also find that there is a significant anisotropy of the magnetic correlation length in UCoGe that contrasts with an almost isotropic length for UGe(2).

Large volume high-pressure cell for inelastic neutron scattering.

Inelastic neutron scattering measurements typically require two orders of magnitude longer data collection times and larger sample sizes than neutron diffraction studies. Inelastic neutron scattering measurements on pressurised samples are particularly challenging since standard high-pressure apparatus restricts sample volume, attenuates the incident and scattered beams, and contributes background scattering. Here, we present the design of a large volume two-layered piston-cylinder pressure cell with optimised transmission for inelastic neutron scattering experiments.

Turnbuckle diamond anvil cell for high-pressure measurements in a superconducting quantum interference device magnetometer.

We have developed a miniature diamond anvil cell for magnetization measurements in a widely used magnetic property measurement system commercial magnetometer built around a superconducting quantum interference device. The design of the pressure cell is based on the turnbuckle principle in which force can be created and maintained by rotating the body of the device while restricting the counterthreaded end-nuts to translational movement. The load on the opposed diamond anvils and the sample between them is generated using a hydraulic press.

Insight, global functioning and psychopathology amongst in-patient clients with schizophrenia.

To explore whether cognitive impairment and global functioning can predict the degree of insight into illness as well as whether insight is mediated by specific symptom dimensions of psychopathology in schizophrenia. A dimensional/cross sectional approach was used. A mixed group of clients (n = 36) were assessed as part of a routine clinical evaluation.

Coexistence and interplay of superconductivity and ferromagnetism in URhGe.

As ferromagnetism and superconductivity are usually considered to be antagonistic, the discovery of their coexistence in UGe(2), URhGe, UIr and UCoGe has attracted a lot of interest. The mechanism to explain such a state has, however, not yet been fully elucidated. In these compounds superconductivity may be unconventional: Cooper pairs could be formed by electrons with parallel spins and magnetic fluctuations might be involved in the pairing mechanism.

High pressure synthesis of late rare earth RFeAs(O,F) superconductors; R = Tb and Dy.

New TbFeAs(O,F) and DyFeAs(O,F) superconductors with critical temperatures T(c) = 46 and 45 K and very high critical fields, >or=100 T, have been prepared at 1100-1150 degrees C and 10-12 GPa, demonstrating that high pressure may be used to synthesise late rare earth derivatives of the recently reported RFeAs(O,F) (R = La-Nd, Sm, Gd) high temperature superconductors.
