A review of the impact of sensory processing sensitivity on mental health in university students
Authors: Mac Allison , Kim Myo-Kyoung , Sevak Rajkumar J. 
Published: August 2024

Abstract

Introduction
The concept of sensory processing sensitivity (SPS) was first introduced by Aron and Aron (1996) as an innate trait characterized by heightened processing of sensory, emotional, and physical stimuli. Since the concept’s introduction in 1996, high SPS has been shown to be associated with poor physical and mental health. It is possible that this is especially true in university students, who are frequently faced with numerous stressors, such as intense workloads and test anxiety.

Methods
This article is a systematic literature review conducted through EBSCOHost using the following databases: Academic Search Complete, APA PsycArticles, APA PsycInfo, Education Research Complete, ERIC, MEDLINE Complete, and SocINDEX. Search terms included terms regarding high sensory processing sensitivity, university or professional students, and mental health.

Results
A total of 6 studies were included. University students with high SPS experienced heightened reactions to sensory, emotional, and physical stimuli. The studies demonstrate correlations of high SPS with outcomes such as depressive tendencies and difficulty adjusting to college.

Discussion
These findings highlight that SPS is associated with poor mental health outcomes. The results underscore the importance of developing support methods for students with high SPS. Future studies should further explore SPS in university students to develop targeted support methods and programs.

AbstractGPS data reveal that the Brahmaputra Valley has broken from the Indian Plate and rotates clockwise relative to India about a point a few hundred kilometers west of the Shillong Plateau. The GPS velocity vectors define two distinct blocks separated by the Kopili fault upon which 2–3 mm/yr of dextral slip is observed: the Shillong block between longitudes 89 and 93°E rotating clockwise at 1.15°/Myr and the Assam block from 93.5°E to 97°E rotating at ≈1.13°/Myr. These two blocks are more than 120 km wide in a north‐south sense, but they extend locally a similar distance beneath the Himalaya and Tibet. A result of these rotations is that convergence across the Himalaya east of Sikkim decreases in velocity eastward from 18 to ≈12 mm/yr and convergence between the Shillong Plateau and Bangladesh across the Dauki fault increases from 3 mm/yr in the west to >8 mm/yr in the east. This fast convergence rate is inconsistent with inferred geological uplift rates on the plateau (if a 45°N dip is assumed for the Dauki fault) unless clockwise rotation of the Shillong block has increased substantially in the past 4–8 Myr. Such acceleration is consistent with the reported recent slowing in the convergence rate across the Bhutan Himalaya. The current slip potential near Bhutan, based on present‐day convergence rates and assuming no great earthquake since 1713 A.D., is now ~5.4 m, similar to the slip reported from alluvial terraces that offsets across the Main Himalayan Thrust and sufficient to sustain a Mw ≥ 8.0 earthquake in this area.
A blocking view of the stratosphere‐troposphere coupling

Published: July 2014

AbstractDynamical influence from the stratosphere is known to play a role in shaping the wintertime tropospheric circulation patterns. Observations suggest that this influence is strongest following weak and strong polar vortex events, termed sudden stratospheric warmings (SSWs) and vortex intensification (VI) events, respectively. In this work, stratosphere‐troposphere coupling is studied through the modulation by extreme vortex events of the Northern Hemispheric tropospheric blocking frequency and eddy‐driven jet displacements. This is done using three reanalysis data sets and the Centro Euro‐Mediterraneo sui Cambiamenti Climatici Climate Model with a resolved Stratosphere (CMCC‐CMS) coupled model control run. Reanalysis results suggest the existence of distinct patterns of blocking activity following extreme vortex events. Over the Atlantic basin, SSWs are shown to lead by about 20–50 days the occurrence of increased/reduced blocking frequency on the poleward/equatorward side of the Atlantic jet stream. Anomalies of the opposite sense, with poleward reduction and equatorward enhancement of the blocking frequency, occur following VI events. The response over the Pacific sector is less clear. Compared to reanalyses, CMCC‐CMS shows a similar but weaker response, especially over the Atlantic: a possible explanation is identified in the different structure of the polar vortex and weaker wind shear anomalies with respect to reanalysis. We finally highlight that patterns identified following vortex extremes show similarities with the Northern Annular Mode over the Atlantic but not over the Pacific. This suggests that the stratosphere‐troposphere coupling is more a regional than annular feature.
Impact of EOS MLS ozone data on medium‐extended range ensemble weather forecasts
Authors: Cheung J. C. H. , Haigh J. D. , Jackson D. R. 
Published: July 2014

AbstractAs the stratosphere is largely characterized by its ozone abundance, the quality of the ozone field is important for a realistic representation of the stratosphere in weather and climate models. While the stratosphere is directly affected by radiative heating from ozone photodissociation, ozone abundance might also impact the representation of the troposphere since the stratosphere and troposphere are dynamically linked. In this paper, we examine the potential benefits of using ozone data from the Earth Observing System (EOS) Microwave Limb Sounder (MLS) for medium‐extended range tropospheric forecasts in a current numerical weather prediction system. The global component of the Met Office Global and Regional Ensemble Prediction System is used, which is run at a resolution of N216 L85 with 24 ensemble members. We compare two scenarios of 31 day forecasts covering the same period, one with the current operational ozone climatology and the other with a monthly mean zonally averaged ozone field computed from the MLS data set. In the extreme case of the Arctic “ozone hole” of March 2011, our results show a general reduction in stratospheric forecast errors in the tropics and Southern Hemisphere as a result of the improved representation of ozone. However, even in such a scenario, where the MLS ozone field is much superior to that of the control, we find that tropospheric forecast errors in the medium‐extended range are dominated by the spread of ensemble members and no significant reduction in the root‐mean‐square forecast errors.

Published: July 2014

ABSTRACTThis article describes the development of new carbon black material from agricultural waste (wood apple shells) by using pyrolysis method at various carbonization temperatures (400, 600, and 800°C) and used as reinforcement in polymer composites. The wood apple shell carbon black (WAS‐CB) particulates are characterized by proximate analysis, energy dispersive spectroscopy (EDS), and scanning electron microscope (SEM). Results showed that due to increases in carbonization temperature the percentage of carbon improved in the carbon black particles. Furthermore, various tests were performed to determine the effect of new carbon black material on the mechanical properties of composite at different filler loading. The results indicated that mechanical properties like tensile strength, tensile modulus, flexural strength, and flexural modulus are improved as the increase in the carbonization temperature and filler loading. The filler‐matrix bonding was analyzed by SEM. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41211.
Lean forward: Genetic analysis of temperature‐sensitive mutants unfolds the secrets of oligomeric protein complex assembly
Authors: McMurray Michael 
Published: July 2014

Multisubunit protein complexes are essential for cellular function. Genetic analysis of essential processes requires special tools, among which temperature‐sensitive (Ts) mutants have historically been crucial. Many researchers assume that the effect of temperature on such mutants is to drive their proteolytic destruction. In fact, degradation‐mediated elimination of mutant proteins likely explains only a fraction of the phenotypes associated with Ts mutants. Here I discuss insights gained from analysis of Ts mutants in oligomeric proteins, with particular focus on the study of septins, GTP‐binding subunits of cytoskeletal filaments whose structures and functions are the subject of current investigation in my and many other labs. I argue that the kinds of unbiased forward genetic approaches that generate Ts mutants provide information that is largely inaccessible to modern reverse genetic methodologies, and will continue to drive our understanding of higher‐order assembly by septins and other oligomeric proteins.Also watch the Video Abstract.
Distinctive Potential Behavior at the Oxidized Surface of a Semiconductor Device in a Concentrated Aqueous Salt Solution
Authors: Maekawa Yuki , Shibuta Yasushi , Sakata Toshiya 
Published: July 2014

AbstractConventional electric double layer (EDL) models do not necessarily apply to concentrated solutions such as those found in physiological environments. In this study, we investigated the effect of changing the concentration of a concentrated NaCl solution on the EDL structure formed at the SiO2 surface of a semiconductor‐based ion sensor and backed up the study by using a classical molecular dynamics (MD) simulation. The interfacial potential in the concentrated NaCl solution measured by using the ion sensor showed behavior that differed from that in the dilute solution, which was supported by the calculated potential profile based on the MD simulation. The simulated potential behavior at the SiO2/NaCl solution interface depended strongly on the electrical charge distribution caused by the dipole structure of water molecules and the spatial separation of hydrated ions against the surface charge, unlike that in the bulk solution. Characterization of the solid/liquid interface in concentrated solutions is expected to aid the detection of biomolecular recognition events under biological conditions.

AbstractA novel method for the fabrication of a charge‐transfer complex crystal was developed. Photoirradiation of a solution of TPP[Co(tbp)(CN)2] and TPP[Co(Pc)(CN)2] (tbp=tetrabenzoporphyrin, Pc=phthalocyanine, TPP=tetraphenylphosphonium) gave a molecular conducting crystal of a charge‐transfer complex TPP[Co(tbp)(CN)2]2, which was produced by the process in which the photoexcited electron in tbp was transferred from the LUMO of tbp to that of Pc.

Published: July 2014

AbstractNatural L‐α‐amino acids and L‐norleucine were transformed to the corresponding α‐hydroxy acids by formal biocatalytic inversion or retention of absolute configuration. The one‐pot transformation was achieved by a concurrent oxidation reduction cascade in aqueous media. A representative panel of enantiopure (R)‐ and (S)‐2‐hydroxy acids possessing aliphatic, aromatic and heteroaromatic moieties were isolated in high yield (67–85 %) and enantiopure form (>99 % ee) without requiring chromatographic purification.

AbstractThe actin filament‐binding and filament‐severing activities of the aplyronine, kabiramide, and reidispongiolide families of marine macrolides are located within the hydrophobic tail region of the molecule. Two synthetic tail analogues of aplyronine C (SF‐01 and GC‐04) are shown to bind to G‐actin with dissociation constants of (285±33) and (132±13) nM, respectively. The crystal structures of actin complexes with GC‐04, SF‐01, and kabiramide C reveal a conserved mode of tail binding within the cleft that forms between subdomains (SD) 1 and 3. Our studies support the view that filament severing is brought about by specific binding of the tail region to the SD1/SD3 cleft on the upper protomer, which displaces loop‐D from the lower protomer on the same half‐filament. With previous studies showing that the GC‐04 analogue can sever actin filaments, it is argued that the shorter complex lifetime of tail analogues with F‐actin would make them more effective at severing filaments compared with plasma gelsolin. Structure‐based analyses are used to suggest more reactive or targetable forms of GC‐04 and SF‐01, which may serve to boost the capacity of the serum actin scavenging system, to generate antibody conjugates against tumor cell antigens, and to decrease sputum viscosity in children with cystic fibrosis.

Published: July 2014

AbstractThe nitroxyl radical 3‐oxo‐9‐azabicyclo [3.3.1]nonane‐N‐oxyl (3‐oxo‐ABNO) has been prepared using a simple protocol. This organocatalyst is found to be an efficient catalyst for the aerobic oxidation of a wide variety of alcohols under metal‐free conditions. In addition, the preparation and characterization of a supported version of 3‐oxo‐ABNO on ordered mesoporous silica SBA‐15 (SABNO) is described for the first time. The catalyst has been characterized using several techniques including simultaneous thermal analysis (STA), transmission electron microscopy (TEM), and nitrogen sorption analysis. This catalyst exhibits catalytic performance comparable to its homogeneous analogue and much superior catalytic activity in comparison with (2,2,6,6‐tetramethylpiperidin‐1‐yl)oxy (TEMPO) for the aerobic oxidation of almost the same range of alcohols under identical reaction conditions. It is also found that SABNO can be conveniently recovered and reused at least 12 times without significant effect on its catalytic efficiency.

AbstractAn efficient microwave‐assisted synthesis of tertiary propargylamines has been developed by copper(I)‐catalyzed decarboxylative A3‐coupling reaction of an alkynylcarboxylic acid with a secondary amine and an aldehyde. A wide range of diversely substituted propargylamines could be synthesized in high yields. The optimal reaction conditions are also effective for 3‐alkylpropiolic acids and for terminal propiolic acid.
How and Why Do Cluster Size, Charge State, and Ligands Affect the Course of Metal‐Mediated Gas‐Phase Activation of Methane?
Authors: Schwarz Helmut 
Published: July 2014

AbstractRecent progress in the gas‐phase activation of methane is discussed. We demonstrate that cluster size, charge state, and ligands crucially affect both the reactivity and selectivity of metal‐mediated bond activation processes. We outline the important role that relativistic effects and spin densities play and discuss the paradigm of two‐state reactivity in thermal reactions. State‐of‐the‐art mass‐spectrometry based experiments, in conjunction with electronic structure calculations, permit identification of the elementary steps at a strictly molecular level and thus allow to uncover mechanistic features for four types of reactions: (i) metal‐mediated dehydrogenation of methane, (ii) ligand‐switch processes of the type ML + CH4→ M(CH3) + HL, (iii) hydrogen‐atom abstraction as the crucial step in the oxidative coupling of methane, and (iv) the mechanism of the challenging CH4→CH3OH conversion.
Performance of diffusion distillation column for production of fuel grade ethanol
Authors: Singh Neetu , Prasad Ram 
Published: July 2014

AbstractBACKGROUNDDiffusion distillation process was used for separation of ethanol–water mixtures of azeotropic composition. Experimental results were compared with a Stefan–Maxwell equations based mathematical model by assuming point behavior of the process.RESULTSThe performance of a diffusion distillation column for anhydrous ethanol production has been investigated by extending the point behavior to an integral column under process relevant operating conditions. New modeling results are in better agreement with the experimental data than old modeling results. The maximum variation in selectivity is obtained at lowest flow rate (0.05 mol m‐1 s‐1).CONCLUSIONSThe diffusion distillation column should be operated at the lowest possible feed rate and the highest possible vaporization temperature to minimize the column length requirement for anhydrous ethanol production. The effect of selectivity on enrichment of ethanol is negligible in long diffusion distillation columns and flux to flow ratio is more important for determination of enrichment. © 2014 Society of Chemical Industry
The dominant synoptic‐scale modes of North American monsoon precipitation
Authors: Seastrand Simona , Serra Yolande , Castro Christopher , Ritchie Elizabeth 
Published: July 2014

ABSTRACTIn this study, we explore the mechanisms of synoptic rainfall variability using observations from the Tropical Rainfall Measuring Mission satellite. Although previously shown to have an important impact on North American monsoon rainfall, tropical cyclones are excluded from this analysis, in order to focus on more frequent synoptic disturbances within the region. A rotated empirical orthogonal function (EOF) analysis of North American monsoon rainfall during June to September 2002–2009 suggests that low‐level tropical disturbances contribute to the leading two modes of precipitation variability within this region. These disturbances result in gulf surges or low‐level surges of moisture up the Gulf of California, and provide a key moisture source to facilitate the development of organized convection. In the first mode, the low‐level trough brings precipitation to lower elevations along the western slopes of the Sierra Madre Occidental south of Hermosillo, Mexico and over the southern Baja Peninsula. In the second mode, the low‐level trough interacts with an upper‐level inverted trough enhancing precipitation into the southwestern United States and northwest Mexico. In particular, the upper‐level trough contributes to the easterly to northeasterly shear across the region, favouring mesoscale convective organization and enhanced deep convection over the Sierra Madre Occidental and higher elevations in southeast Arizona. The EOF methodology offers an objective approach for determining the dominant modes of precipitation for the monsoon region useful for identifying past and monitoring future low‐frequency impacts on these modes.

Fan‐shaped antenna with triband‐notched characteristic for UWB applications
Authors: Ojaroudi N. , Mehranpour M. , Ghadimi N. 
Published: July 2014

ABSTRACTIn this article, a novel design of ultrawideband (UWB) microstrip monopole antenna with enhanced bandwidth and triple band‐notched characteristics has been presented. The antenna consists of fan‐shaped radiating patch with a pair of L‐shaped parasitic structure, a feed‐line with an S‐shaped step‐impedance resonator (SIR) slot and modified ground plane with pairs of T‐shaped strips protruded inside the rectangular slots. In the proposed design, by cutting two rectangular slots with pairs of protruded T‐shaped strips in the ground plane, additional resonances are excited and much wider impedance bandwidth can be produced. Using these modified structures, the usable upper frequency of the antenna is extended from 10.3 to 17.4 GHz. To generate a single band‐notched function, we add a pair of L‐shaped parasitic structures to the fan‐shaped radiating patch. Also, by cutting the S‐shaped SIR at the feed line, dual and triple band‐notched properties are achieved. The measured results reveal that the presented dual band‐notched antenna offers a very wide bandwidth from 2.8 to 17.4 GHz, with three notched bands around of 5–6 GHz wireless local area network, 7.25–7.75 GHz downlink of X‐band satellite communication system, and 8.02–8.4 GHz International Telecommunication Union bands. The antenna configuration is simple, easy to fabricate and can be integrated into UWB systems. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2426–2430, 2014
